[0061] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0062] 1) The present invention provides an automated production line for a coreless motor rotor. An assembly mechanism can assemble the parts of the coreless motor rotor together. A wire winding mechanism can press a circle of wire ends standing on the wire cup onto a circle of commutator segments of the commutator. A welding mechanism can weld a circle of wire ends on the wire cup to a circle of commutator segments on the commutator. A transport mechanism can transport the wire cup, rotor frame, commutator and their assembly structure. This can maximize production efficiency and has a high degree of automation.

[0063] 2) The present invention provides an automated production line for coreless motor rotors, and the carrier is reasonably designed. The mold core can be easily loaded into the base, and the first positioning plane on the base matches the second positioning plane on the mold core, so that the base can move and rotate with the mold core, thereby facilitating the various parts of the coreless motor rotors carried on the carrier to be moved together to the various processing stations for processing and rotated at the stations for processing, thereby facilitating the realization of automated production on the production line.

Then the sliding sleeve moves upward, and the lower end of the clamp releases the clamping force on the commutator, releasing the commutator and allowing the commutator to be placed on the rotor frame, making it convenient for the subsequent pressing tools on the production line to continue to press the commutator into the rotor frame, thereby helping to realize production automation and improve production efficiency.

[0066] 5) In the automated production line for hollow cup motor rotors of the present invention, the clamping claws of the pneumatic clamps of the press-fitting device can clamp the wire cup, and the die above the clamping claws can move downward to press down the rotor frame pre-placed on the upper end of the inner wall of the wire cup together with the rotor shaft on the rotor frame. The pressing force and stroke of the cylinder are easy to control, so that the rotor frame can be pressed to a suitable depth, with a high degree of automation and a reduced defective product rate.

[0067] 6) In an automated production line for coreless motor rotors of the present invention, the motor of the wire winding mechanism can drive the rotating shaft and the carrier positioning block on the rotating shaft to rotate, thereby rotating the carrier mounted on the carrier positioning block and the coreless motor rotor carried on the carrier, so that the wire pressing device arranged next to the rotating base can automatically press the wire ends on the wire cup of the coreless motor rotor, thereby helping to realize the automation of wire pressing.

[0068] 7) In the automated production line of a coreless motor rotor of the present invention, the fixture can receive the rotor frame, and the motor and the rotating shaft can drive the tooling to rotate, thereby driving the rotor frame of the coreless motor rotor positioned on the tooling to rotate, making it convenient to perform gluing, spot welding and assembling the commutator on the rotor frame of the coreless motor rotor on the production line, thereby facilitating production automation; in addition, since the positioning pin has pre-positioned the rotor frame, the commutator can be easily installed on the rotor frame BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0116] Referring to the accompanying drawings, an automated production line for a coreless motor rotor is provided.

The automated production line includes an assembly mechanism, a winding mechanism, a welding mechanism and a transfer mechanism. The assembly mechanism includes a rotary pressing device 20 and a pressing device 40. The rotary pressing device 20 is used to assemble the commutator 10103 and the rotor frame 10102. The pressing device 40 can continue to press the commutator 10103 into the set position of the rotor frame 10102. After the commutator 10103 and the rotor frame 10102 are assembled, the rotor frame 10102 is pressed into the wire cup 10104.

[0117] The assembly mechanism is used to assemble the commutator on the rotor frame and to assemble the rotor frame equipped with the commutator on the wire cup, wherein the commutator has a circle of commutator segments, and a circle of wire ends of the wire cup is in an upright state.

[0118] The wire winding mechanism 60 is used to press a circle of wire ends standing on the wire cup onto a circle of commutator segments of the commutator.

[0119] The welding mechanism is used to weld a circle of wire ends on the wire cup with a circle of commutator segments on the commutator, wherein one wire end is welded on each commutator segment. The first welding mechanism 30 can firstly spot weld the commutator segments, and then the second welding mechanism 70 can be used to weld the wire ends to the commutator segments.

[0123] The baking mechanism 50 is used to dry the glue on the rotor shaft and the glue on the outer side of the rotor frame. The baking mechanism 50 can be set at multiple locations to dry the glue and transfer the hollow cup motor rotor at multiple locations.

[0124] The glue dispensing mechanism is also used for dispensing glue at the end of the joint between the wire cup and the commutator (realized by the second glue dispensing mechanism 80) and at the joint between the wire end and the commutator segment (realized by the second glue dispensing mechanism 80) after a circle of wire ends on the wire cup are welded to a circle of commutator segments on the commutator;

[0125] The baking mechanism is also used to dry the glue applied at the end of the joint between the wire cup and the commutator and the glue applied at the joint between the wire head and the commutator segment.

[0126] The transfer mechanism of the present invention includes a carrier, which can carry a coreless motor rotor 10100, and moves on a track driven by a manipulator or a material-dispensing device of the transfer mechanism. The coreless motor rotor 10100 includes a wire cup 10104, a rotor frame 10102, a rotor shaft 10101 and a commutator 10103.

When the mold core 10102 is installed on the base 101, the first positioning plane 1013 and the second positioning plane 1022 should be aligned, and then the lower end of the mold core 10102 is inserted into the mounting hole of the base 101. The second positioning plane 1022 is set so that the mold core 10102 forms a second flat position (axial flat position) at the position of the second positioning plane 1022.

[0133] The rotor frame 10102 is generally a plastic part, which mainly plays a supporting role, and serves as the installation base of the commutator 10103, the rotor shaft 10101 and the wire cup 10104, and is used to install and support the commutator 10103. The rotor frame 10102 limits the rotational freedom of the commutator 10103. In the preferred solution, a plurality of positioning grooves are arranged circumferentially on the rotor frame 10102, and the commutator 10103 is arranged with positioning bosses at positions corresponding to the positioning grooves, and the positioning bosses are inserted into the positioning grooves, so that the rotor frame 10102 and the commutator 10103 can rotate together, and prevent the commutator 10103 from rotating misaligned during rotation, which affects the normal welding of the commutator 10103 and the wire cup 10104. The commutator 10103 is installed on the rotor frame 10102, and the wire cup 10104 is sleeved on the rotor frame 10102, and the wire ends on the wire cup 10104 are welded to the commutator 10103. During welding, in order to protect the commutator 10103, a sleeve 10105 is provided on the outer side of the rotor shaft 10101 to protect the commutator 10103, so that during high-temperature welding, tin beads and rosin will not splash into the slots of the commutator 10103, thereby preventing the production of defective products.

[0134] The rotor frame 10102 has positioning holes at positions corresponding to the positioning pins 1021. The positioning holes are blind holes, and one positioning pin 1021 can be inserted into one positioning hole, thereby positioning the rotor frame 10102 to prevent the rotor frame 10102 from rotating. After the positioning holes of the rotor frame 10102 are aligned with the positioning pins 1021 and placed on the positioning pins 1021, multiple positioning pins 1021 can support the rotor frame 10102 together.

[0135] The top of the mold core 10102 is provided with an axial hole 1012 for inserting the rotor shaft 10101 of the hollow cup motor rotor. After the positioning hole of the rotor frame 10102 is aligned with the positioning pin 1021 and installed in place, the rotor shaft 10101 can also be inserted into the axial hole 1012, and the axial hole 1012 is preferably a through hole.

[0136] The base 101 is provided with two pin pre-reserved holes 1015 for inserting an inverted U-shaped pin 1016 so that the pin 1016 applies elastic force to press the outer wall of the wire cup 10104 of the hollow cup motor rotor. The wire cup 10104 is sleeved on the outer side of the rotor frame 10102, and the pin 1016 presses on the outer wall of the wire cup 10104 through elastic force to prevent the wire cup 10104 from rotating freely. However, due to the elastic force applied, the rotation of the wire cup 10104 cannot be completely restricted, and the wire cup 10104 is allowed to have a relatively small degree of rotation freedom.

[0137] During operation, first align the second positioning plane 1022 at the lower end of the mold core 10102 with the first positioning plane 1013 in the mounting hole of the base 101, insert the lower end of the mold core 10102 into the mounting hole, and then fix the base 101 and the mold core 10102. Then align the positioning hole on the rotor frame 10102 with the positioning pin 1021 on the mold core 10102, place the rotor frame 10102 on the positioning pin 1021, and at the same time, the rotor shaft 10101 of the rotor frame 10102 also extends into the shaft hole 1012 of the mold core 10102.

[0138] The base 101 of the present invention is provided with a threaded hole connected to the mounting hole, and a bolt is installed at the threaded hole. The bolt rests on the outer wall of the part of the mold core 10102 extending into the mounting hole, thereby fixing the base 101 and the mold core 10102 together.

[0139] Furthermore, a plurality of blind holes are arranged circumferentially on the mold core 10102 , and each of the positioning pins 1021 is inserted into one of the blind holes, so that it is convenient to install the positioning pins 1021 into the blind holes.

[0140] It should be noted that the structures of all carriers on the production line should be consistent, especially the distribution of the positioning pins 1021 on the mold core 10102 should be consistent, and the relative position relationship between the second positioning plane 1022 of each mold core 10102 and the positioning pin 1021 should be consistent, so that it is convenient for the positioning hole at the bottom of the rotor frame 10102 to fall into the positioning pin 1021, so that the rotor frame 10102 can be accurately placed on the positioning pin 1021. In addition to being convenient for installation on the base 101, the second positioning plane 1022 of the mold core 10102 is also used for positioning. The positioning pin 1021 on each mold core 10102 on the production line must be in the same relative position relative to the second positioning plane 1022, and the relative position of the positioning pin 1021 and the second positioning plane 1022 on each mold core 10102 must be consistent to ensure the consistency of the carrier and the consistency of hollow cup production on the production line.

[0141] Furthermore, the mounting hole is provided with an avoidance groove 1014 at each side edge corresponding to the second positioning plane 1022 to avoid the sharp corners on both sides of the first positioning plane 1013. In this way, when the lower end of the mold core 10102 is inserted into the mounting hole, it can effectively prevent the friction between the hole wall of the mounting hole and the sharp corners on both sides of the first positioning plane 1013 from affecting the normal installation of the lower end of the mold core 10102.

[0144] The rotating base includes a mounting platform 2035, a first motor 2037, a carrier positioning block 2042 and a rotating shaft 2054. The first motor 2037 and the carrier positioning block 2042 are respectively mounted on the mounting platform 2035. The rotating shaft 2054 is vertically arranged and rotatably mounted on the mounting platform 2035. The first motor 2037 is connected to the rotating shaft 2054 to drive the rotating shaft 2054 to rotate. The carrier positioning block 2042 is fixedly mounted on the top of the rotating shaft 2054, and the carrier positioning block 2042 is located below the solder gun 209 to drive the carrier fixed on the carrier positioning block 2042 and used to carry the hollow cup motor rotor to rotate, so that the solder gun 209 can weld the commutator and a circle of wire ends of the wire cup of the hollow cup motor rotor together.

[0145] The soldering device further comprises a second motor 202, a screw mechanism, a lifting platform, a cylinder A207, a fixture 2010, a bracket 2011 and a connector 2012, wherein the cylinder A207, the solder gun 209, the fixture 2010, the bracket 2011 and the connector 2012 together constitute a soldering unit, wherein:

[0146] The second motor 202 and the tin-breaking machine 203 are respectively installed on the support seat, and the output shaft of the second motor 202 is connected to the screw 26 of the screw mechanism. The output shaft of the second motor 202 is preferably connected to the screw 26 of the screw mechanism through a coupling 204, which is convenient for disassembly and assembly. The transmission nut 2027 of the screw mechanism is installed on the screw 26 to convert the spiral motion of the screw 26 into linear motion. The transmission nut 2027 of the screw mechanism is connected to the lifting platform to drive the lifting platform to move up and down; the output shaft of the second motor 202 is connected to an encoder 201, which can accurately control the rotation of the screw 26 and the up and down movement of the transmission nut 2027. The tin-breaking machine 203 can press out small holes on the tin wire to improve the welding environment, so that the flux is vaporized when heated and overflows from the hole, thereby enhancing the solderability and fluidity of the solder and preventing the occurrence of the "tin explosion" phenomenon. After the pay-off reel with the tin wire wound around it is placed on the tin breaking machine 203, the tin wire can come out of the tin breaking machine 203 to realize automatic tin wire feeding.

[0147] The cylinder A207 is installed on the lifting platform, and the solder gun 209 is installed on the output shaft of the cylinder A207, and the head of the solder gun 209 is facing downward; the head of the solder gun 209 is preferably tilted relative to the horizontal plane. The up and down movement of the lifting platform can drive the solder gun 209 to move up and down. The cylinder A207 is preferably a slide cylinder, and the solder gun 209 is installed on its slide 208. The slide cylinder can achieve high precision and high stability in the movement of the solder gun 209.

[0148] The clamp 2010 is sleeved on the outside of the solder gun 209. The clamp 2010 is preferably a clamp sleeved on the outside of the solder gun 209, so that the clamp 2010 is conveniently installed on the outside of the solder gun 209. The clamp 2010 and the connector 2012 are connected together through the bracket 2011. The bracket 2011 and the connector 2012 are respectively provided with through holes, so that the tin wire coming out of the tin breaking machine 203 passes through the through hole of the bracket 2011 and the through hole of the connector 2012 in turn. The two supporting points formed by the two through holes can keep the tin wire passing through relatively stable and not easy to shake. The connector 2012 is arranged corresponding to the position of the gun head of the solder gun 209, so that the gun head of the solder gun 209 melts the tin wire passing through the through hole of the connector 2012, and the tin wire can be automatically fed through the tin breaking machine 203. The solder gun 209 melts the tin wire while the tin breaking machine 203 feeds the tin wire through the through hole of the bracket 2011 and the through hole of the connector 2012, so that automatic welding can be realized. The welding speed of the solder gun 209 matches the feeding speed of the tin wire by the tin breaking machine 203. The wire head of the wire cup has been bonded to the commutator after the previous process. The solder gun 209 melts the tin wire at high temperature and welds a circle of wire head of the wire cup to the commutator.

[0149] Furthermore, a vertical slide rail 205 is installed on the support seat, and the lifting platform is installed on the slide rail 205 to maintain the stability of the lifting platform.

[0150] Furthermore, an induction sheet 2028 is installed on the lifting platform, and a photoelectric sensor 2024 is installed on the support seat.

[0151] Furthermore, the soldering units have two groups and they are symmetrically installed on the lifting platform. Correspondingly, the soldering machines 203 also have two groups and they are installed on the support seat. Since there is a circle of wire ends on the wire cup that needs to be welded to the commutator, the efficiency of soldering can be improved by using two sets of soldering units and soldering machines 203. Two sets of soldering guns 209 can be welded at the same time to improve work efficiency.

[0152] Furthermore, the second motor 202 is a reduction motor having a gearbox 2025 structure, and the lead screw 26 is coaxially connected to the output shaft of the gearbox 2025 of the second motor 202 through a coupling 204 .

[0153] The support seat includes a fixed seat 2033, a fixed platform 2032 installed on the fixed seat 2033, and a mounting bracket 2058 installed on the fixed platform 2032.

The sensing sheet 2028 and the photoelectric sensor 2024 mounted on the mounting bracket 2058 of the support seat work together to feedback the current position of the transmission nut 2027. The first mounting block 2029 and the second mounting block 2030 clamp the guide rail, the third mounting block 2031 is fixedly mounted with the mounting block 30, the mounting plate 206 is fixedly mounted on the third mounting block 2031, and the cylinder A207 is fixedly mounted on the mounting plate 206. Two cylinders A207 are arranged on the transmission nut 2027 in a left-right symmetrical manner. Two sets of solder guns 209, brackets 2011 and connectors 2012 stacked on the left and right are respectively mounted on the slides of the cylinders A207, and the solder guns 209 and the brackets 2011 and connectors 2012 on the solder guns 209 are driven by the cylinders A207 to move up and down.

[0154] The rotating base further includes a guide rail 2048, a cylinder B2018, a rotating shaft 2054, a push rod 2056 and a material-dispensing device, wherein:

[0155] The guide rail 2048 is horizontally mounted on the mounting platform 2035, preferably mounted on the mounting platform 2035 via a mounting seat 2049, and a blocking strip 2047 is provided along the length direction of the guide rail 2048 to block the carrier 2015 for carrying the hollow cup motor rotor that is transported to the guide rail 2048 by a conveying mechanism; the conveying mechanism can be a conveyor belt or a robot. If it is a conveyor belt, the conveyor belt is perpendicular to the guide rail 2048, and the front carrier 2015 is transported to the guide rail 2048 in a direction perpendicular to the guide rail 2048. Since the front carrier 2015 is blocked by the blocking strip 2047, the following carriers 2015 are queued on the conveying mechanism and have to wait for the front carrier 2015 to be sent away before they can be transported to the guide rail 2048 in order.

[0156] The cylinder B2018 is installed on the mounting platform 2035 , the rotating shaft 2054 is vertically arranged and rotatably installed on the mounting platform 2035 , and the first motor 2037 is connected to the rotating shaft 2054 .

[0157] The carrier positioning block 2042 has an inner cavity, and includes a top plate 20421, a side connection block 80422 and a bottom plate 20423 for receiving the carrier 2015. The side connection block 80422 connects the top plate 20421 and the bottom plate 20423. The bottom plate 20423 is provided with a through hole as a moving channel for the top rod. The top plate 20421, the side connection block 80422 and the bottom plate 422 are preferably integrally formed.

[0158] The material shifting device includes a material shifting block 2023 and a multi-axis motion platform, the material shifting block 2023 is installed on the multi-axis motion platform, and a material shifting groove is provided on the material shifting block 2023 so as to shift the carrier 2015 on the guide rail 2048, so that the carrier 2015 can extend into the inner cavity of the carrier positioning block 2042 and be received by the bottom plate 20423 of the carrier positioning block 2042, then the carrier 2015 can be placed on the bottom plate 20423 of the carrier positioning block 2042, and preferably the base 2044 of the carrier 2015 enters the inner cavity of the carrier positioning block 2042.

[0159] The carrier 2015 can have many structural forms, as long as it can carry the hollow cup motor rotor. After the hollow cup motor rotor composed of the coil, rotor frame and commutator 2045 is placed on the carrier 2015, the soldering device above the rotating base can perform welding operations on the hollow cup motor rotor.

[0160] The rotating shaft 2054 has a through hole that passes through from top to bottom. The rotating shaft 2054 and the push rod 2056 are coaxially arranged, and the push rod 2056 is movably installed inside the rotating shaft 2054, that is, the rotating shaft 2054 and the push rod 2056 are not fixed, and the two can have relative movement. The cylinder B2018 is fixedly connected to the lower end of the push rod 2056 to drive the push rod 2056 to move up and down, so that when the push rod 2056 moves upward, the top end of the push rod 2056 cooperates with the top plate 20421 of the carrier positioning block 2042 to clamp the carrier 2015, and when the push rod 2056 moves downward, the clamping of the carrier 2015 is released. The lower end of the push rod 2056 preferably exceeds the lower end of the rotating shaft 2054, so that the cylinder B2018 is connected to the push rod 2056. When the top rod 2056 moves upward, the carrier 2015 is pressed against the top plate 20421, so that the carrier 2015 cannot move. In this way, when the rotating shaft 2054 drives the carrier positioning block 2042 and the carrier 2015 to rotate together, the carrier 2015 will not shift, thereby not affecting the soldering work of the soldering device above the rotating base on the hollow cup motor rotor.

[0161] Cylinder B2018 has a push rod 2019, which is connected to the push rod 2056 through a push rod connector 2057. The push rod 2019 is pushed upward to drive the push rod 2056 to move upward. Cylinder B2018 is fixedly mounted on the mounting platform 2035 through a mounting block.

[0162] Furthermore, the top plate 20421 is provided with a guide groove 204211, and the guide groove 204211 is parallel to the guide rail 2048, so that the carrier 2015 moves along the guide groove 204211 to the carrier positioning block 2042. If a portion of the carrier 2015 extends upward beyond the top plate 20421, the guide groove 204211 can well adapt to the shape of the carrier 2015, so that the carrier 2015 can still enter the inner cavity of the carrier positioning block 2042.

[0163] Furthermore, the carrier 2015 is provided with two mutually parallel first guide surfaces, and correspondingly, the inner wall of the carrier positioning block 2042 is also provided with two mutually parallel second guide surfaces, and each of the second guide surfaces is respectively fitted with one of the first guide surfaces. If both the carrier 2015 and the carrier positioning block 2042 have cylindrical structures, the first guide surface and the second guide surface are respectively formed into flat positions, and the two guide surfaces can make the flat positions fit together well, and can also prevent the carrier 2015 from having rotational displacement when the carrier positioning block 2042 drives the carrier 2015 to rotate, thereby affecting the normal welding of the hollow cup motor rotor by the soldering device.

[0164] Further, the first motor 2037 is connected to the rotating shaft 2054 through a gear mechanism, and the gear mechanism includes a driving gear 2016 and a driven gear 2017, and the driving gear 2016 and the driven gear 2017 are meshed with each other, so the driving gear 2016 is installed on the output shaft of the first motor 2037, and the driven gear 2017 is fixedly installed on the rotating shaft 2054. The driven gear 2017 drives the rotating shaft 2054 to rotate, and the rotating shaft 2054 drives the carrier positioning block 2042 to rotate, and the carrier positioning block 2042 drives the carrier 2015 to rotate, and the carrier 2015 drives the spool 2014 on the carrier 2015 and the hollow cup motor rotor to rotate. The induction sheet 2039 is arranged above the driven gear 2017. The spool 2014 has a spool head 20141.

[0165] Furthermore, the multi-axis mobile platform is an XY-axis motion platform, which is used to drive the material shifting block 2023 to move horizontally, wherein one axis is parallel to the guide rail 2048 and the other axis is perpendicular to the guide rail 2048. When the material shifting block 2023 moves in a direction perpendicular to the guide rail 2048, the material shifting groove can be stuck on the carrier 2015. When it moves in a direction parallel to the guide rail 2048, the carrier 2015 can be moved, so that the carrier 2015 moves along the length direction of the guide rail 2048 to extend into the inner cavity of the carrier positioning block 2042.

[0166] The XY axis motion platform includes a cylinder C2038, a slider, a mounting frame 2022, a second slider 802020 and a cylinder D2021. The material shifting block 2023 is fixedly mounted on the mounting frame 2022, the mounting frame 2022 is fixedly mounted on the first slider 20381, the first slider 20381 is pushed by the cylinder C2038, the cylinder C2038 pushes the first slider 20381 to move forward and backward, the forward and backward movement of the first slider 20381 drives the mounting frame 2022 fixedly connected to the first slider 20381 to move forward and backward, and the forward and backward movement of the mounting frame 2022 drives the forward and backward movement of the material shifting block 2023. At the same time, the cylinder C2038 is fixedly installed on the second slider 802020, and the second slider 802020 is pushed by the cylinder D2021. The cylinder D2021 is fixedly installed on the mounting platform 2035. The cylinder D2021 pushes the second slider 802020 to move left and right, and the cylinder C2038 fixedly installed with the second slider 802020 moves left and right. At the same time, it drives the material shifting block 2023 to move left and right, so that the material shifting block 2023 can achieve the functions of moving forward, right, backward, and left, and move the carrier 2015 carrying the wire cup 2014 and the rotor frame that have not yet undergone the welding process to the bottom of the soldering gun for welding operations.

[0167] Furthermore, the present invention further comprises an encoder, a photoelectric sensor 2040 and a sensing block, wherein the encoder is connected to the output shaft of the first motor 2037, and the photoelectric sensor 2040 and the sensing block are respectively mounted on the mounting platform 2035 and the rotating shaft 2054, so as to obtain the rotation information of the rotating shaft 2054. The encoder can obtain the rotation angle of the rotating shaft 2054, and the photoelectric sensor 2040 and the sensing block can cooperate to obtain the initial position of the rotating shaft 2054, and the encoder, the photoelectric sensor 2040 and the sensing block can cooperate to obtain the rotation position of the rotating shaft 2054.

[0168] Furthermore, the rotating shaft 2054 is mounted on the mounting platform 2035 via a bearing, an outer wall of the rotating shaft 2054 is provided with an external thread, and a locking nut 2053 is connected to the external thread of the rotating shaft 2054, thereby locking the rotating shaft 2054 on the inner ring of the bearing to prevent axial shaking when the rotating shaft 2054 rotates. The rotating shaft 2054 is relatively long and is mounted on the mounting platform 2035 via two bearings, namely a first bearing 2051 and a second bearing 2055. The first bearing 2051 is above the second bearing 2055, and the locking nut 2053 locks the rotating shaft 2054 on the inner ring of the first bearing 2051.

[0169] Furthermore, a receiving hole is provided on the guide rail 2048, and the carrier positioning block 2042 is located at the receiving hole. Then, the carrier positioning block 2042 divides the guide rail 2048 into two sections, one section is used to allow the carrier 2015 to enter the carrier positioning block 2042, and the other section is used to allow the carrier 2015 that has completed the welding process to leave the carrier positioning block 2042 and move to the next process.

[0170] Furthermore, the plane of the bottom plate 20423 used to support the carrier 2015 is coplanar with the plane of the guide rail 2048 used to support the carrier 2015 , which facilitates the carrier 2015 on the guide rail 2048 to enter and exit the carrier positioning block 2042 .

[0171] Furthermore, the guide groove 204211 on the top plate 20421 is arranged throughout the length, and there are two material shifting grooves on the material shifting block 2023, and the two material shifting grooves are arranged along the length direction of the guide rail 2048, so as to be used to shift one of the carriers 2015 into the carrier positioning block 2042 and shift the other carrier 2015 out of the carrier positioning block 2042 at the same time.

[0172] The base rotating device is integrally arranged below the soldering gun of the soldering device. The first motor 2037 is preferably a reduction first motor 2037, which has a gear box 2036. The driving gear 2016 is fixedly mounted on the output shaft of the gear box 2036. The first motor 2037 is connected to an encoder to form a closed-loop control. The gear box 2036 is fixedly mounted on the flange 2041 and fixedly mounted with the mounting platform 2035 through the flange 2041. The rotating shaft 2054 is fixedly mounted on the mounting platform 2035 through a bearing. A plurality of support columns 2034 are respectively arranged around the mounting platform 2035 for mounting with the table of the production line.

[0173] A locking nut 2053 is arranged above the induction sheet 2039, and a bearing and a bearing support ring 2050 are arranged at the upper end of the locking nut 2053. The bearing and the bearing support ring 2050 are arranged inside the bearing seat 2052, and the bearing seat 2052 is installed on the mounting platform 2035. The carrier positioning block 2042 is arranged at the upper end of the rotating shaft 2054 and is fixedly installed with the rotating shaft 2054. The wire cup 2014 and the rotor of the hollow cup first motor 2037 are arranged on the carrier 2015 at the same time. The outer side of the rotor shaft 2043 of the hollow cup first motor 2037 is sleeved with a sleeve 2013. The sleeve 2013 is used to protect the commutator 2045. In the case of high-temperature welding, the tin beads and rosin will not splash into the slots of the commutator 2045 to prevent the generation of defective products.

[0174] The working process of the present invention is as follows:

[0175] The second motor 202 rotates after being energized, driving the lead screw 26 to rotate. The rotation of the lead screw 26 drives the transmission nut 2027 meshing therewith to move downward, thereby driving the soldering gun 209 fixedly mounted on the transmission nut 2027 to move downward. The position of the transmission nut 2027 is determined by the induction sheet 2028 and the photoelectric sensor 2024. When the transmission nut 2027 drops to the set position, the second motor 202 is powered off, and the transmission nut 2027 is stopped at the current position through the self-locking mode of the lead screw 26 and the transmission nut 2027.

[0176] The cylinder C2038 pushes the first slider 20381 forward, driving the material-dispensing block 2023 installed with the first slider 20381 to move forward, and the material-dispensing groove on the material-dispensing block 2023 is stuck on the carrier 2015. Then, the cylinder D2021 pushes the second slider 802020 to move rightward, and the movement of the second slider 802020 drives the material-dispensing block 2023 to move rightward. The material-dispensing block 2023 drives the carrier 2015 to move rightward under the push of the cylinder D2021. The flat part of the carrier 2015 is loaded into the carrier positioning block 2042, and at the same time, the cylinder B2018 pushes the push rod 2019 upward, and the push rod 2019 pushes the push rod 2056 through the connector 2057, so that the push rod 2056 moves upward, supports the mold core of the carrier 2015, and fixes the carrier 2015 between the carrier positioning blocks 2042. At the same time, the material shifting block 2023 retreats backward, then moves to the left and returns to the initial position.

[0177] After the rotating base 2020 under the soldering device sends the carrier to the bottom of the solder gun 209, the cylinder A207 distributed on both sides of the lead screw 26 pushes the slide 208 to move downward, and the solder gun 209 installed on the slide 208 and the bracket 2011 and the connector 2012 for loading the solder wire all move downward. After the pair of solder guns 209 are powered on, the two wire ends in the wire cup 2014 are welded together with the commutator 2045 (the wire ends are initially upright, and are first pressed to a roughly horizontal position by the horizontally moving external pressure head before welding). After welding, the pair of solder guns 209 are withdrawn.

[0178] The first motor 2037 drives the driving gear 2016 to rotate, and then drives the driven gear 2017 meshing with the driving gear 2016 to rotate. The rotation of the driven gear 2017 drives the rotating shaft 2054 fixedly mounted with the driven gear 2017 to rotate. The rotation of the rotating shaft 2054 drives the induction sheet 2039 installed on the rotating shaft 2054 to rotate, and drives the carrier positioning block 2042 to rotate. The carrier positioning block 2042 drives the carrier 2015 to rotate. The rotation angle of the rotating shaft 2054 is determined by the induction sheet 2039 and the photoelectric sensor 2040. Since the position of the thread end is generally odd, when there is only one thread end left that has not been welded, the solder gun will be on one side next time, so that each thread end of the wire cup 2014 is welded to the commutator 2045.

[0179] After welding is completed, the push rod 2019 falls back, pulling the ejector rod 2056 back, and the ejector rod 2056 releases the clamping of the carrier 2015, so that the material shifting block 2023 of the next process can smoothly shift the carrier 2015 away from the carrier positioning block 2042.

[0180] The baking mechanism of the present invention comprises a heat-insulating shell, an electric heating device and a carrier conveying mechanism, wherein:

[0181] The electric heating device is installed on the heat-insulating shell, and the electric heating device includes an electric heating tube 3018 located inside the heat-insulating shell; a through hole 3044 is provided on the heat-insulating shell for outlet of electric wires for energizing the electric heating tube 3018.

The first motor 301 is connected to the chain 3038 through a gear transmission mechanism to drive the chain-plate conveyor belt 3015 to move to transport the carrier equipped with the hollow cup motor rotor.

[0183] The heat-insulating housing preferably includes three shells connected in sequence from top to bottom, namely a top shell, a middle shell and a bottom shell, and the three shells are assembled together.

[0184] Each shell includes an inner insulation layer, a middle insulation layer and an outer insulation layer arranged from the inside to the outside, and the inner insulation layer and the outer insulation layer are fixedly connected so that the inner insulation layer and the outer insulation layer cooperate to wrap the middle insulation layer.

[0185] The electric heating device is preferably mounted on the top shell of the heat-insulating housing, and the electric heating device further comprises a second motor 3010, a wind wheel 3017 and a mounting frame 3029, wherein:

[0186] The top shell includes an inner insulation layer 3028, a middle insulation layer and an outer insulation layer 309 arranged from the inside to the outside. The inner insulation layer 3028 and the outer insulation layer 309 are fixedly connected, so that the inner insulation layer 3028 and the outer insulation layer 309 cooperate to wrap the middle insulation layer; in order to reduce the transfer and dissipation of heat, the outer insulation layer 309 and the inner insulation layer 3028 are preferably made of metal materials and fixed by welding, so that the middle insulation layer is sealed in the space between the outer insulation layer 309 and the inner insulation layer 3028, so that the outer insulation layer 309 and the inner insulation layer 3028 wrap the middle insulation layer as a whole. The middle insulation layer is preferably made of insulation cotton. The insulation cotton has the characteristics of high temperature resistance, non-flammability, low thermal conductivity, and good insulation effect. A plurality of handles 3026 are arranged on the outer insulation layer 309 of the top shell, and the handles 3026 are convenient for moving the top shell of the insulation shell as a whole.

[0187] The motor housing of the second motor 3010 is located outside the outer heat insulation layer 309, and the motor housing of the second motor 3010 is fixedly mounted on the outer heat insulation layer 309. The outer heat insulation layer 309 is preferably fixed with a flange 3016, and the flange 3016 is located outside the outer heat insulation layer 309, and the motor housing of the second motor 3010 is mounted on the outer heat insulation layer 309 through the flange 3016. The flange 3016 can also play a certain heat insulation effect.

[0188] The output shaft of the second motor 3010 is connected to the heat-insulating sleeve, which is rotatably mounted on the heat-insulating outer shell, and the heat-insulating sleeve extends into the heat-insulating outer shell and is connected to the wind wheel 3017. A gap is left between the wind wheel 3017 and the inner heat-insulating layer 3028, and the two are not in contact, and the inner heat-insulating layer 3028 will not affect the normal rotation of the wind wheel 3017. The wind wheel 3017 can circulate the heat in the oven to keep the temperature in the oven within ±10°C of the set value.

[0189] The mounting frame 3029 is mounted on the inner wall of the heat-insulating inner layer of the top shell of the heat-insulating shell. The mounting frame 3029 is preferably fixedly mounted on the heat-insulating inner layer by screws, and the electric heating tube 3018 is fixedly mounted on the mounting frame 3029. The electric heating tube 3018 is a serpentine tube. The electric heating tube 3018 is connected with an electric wire, and the electric wire passes through the heat-insulating shell and is sealed and connected to the heat-insulating shell. The heat-insulating shell is provided with an electric wire outlet for energizing the electric heating tube 3018. The electric heating tube 3018 is energized and heated by the electric wire, thereby heating the air inside the heat-insulating shell. If a conveyor belt is set in the heat-insulating shell, the rotor of the hollow cup second motor 3010 carried by the carrier can be baked in the heat-insulating shell during the process of conveying the carrier by the conveyor belt. The electric heating tube 3018 is preferably fixed to the mounting frame 3029 by a pipe clamp, which is convenient for disassembling and assembling the electric heating tube 3018.

[0190] Furthermore, two electric heating tubes 3018 are arranged, and the wind wheel 3017 is located between the two electric heating tubes 3018. The electric heating tubes 3018 are heated symmetrically, so that the temperature can be quickly raised to the set temperature, and combined with the wind wheel 3017 between the two, the air temperature in the heat-insulating shell can be distributed more evenly.

[0191] Furthermore, the top shell of the heat-insulating shell is a cover body with an open lower end, and the open end of the top shell of the heat-insulating shell can cover the middle shell below it, the middle shell is a shell that penetrates from top to bottom, and the lower shell is a shell with an open upper end. The top shell, the middle shell and the bottom shell are assembled together to form a heat-insulating shell with a relatively large internal space, and a conveyor chain or the like can be installed in this large heat-insulating shell to transport the carrier.

[0192] Furthermore, the heat insulating shell is a rectangular parallelepiped structure as a whole, and limit blocks 3025 are respectively installed at the four corners of the outer side of the top shell of the heat insulating shell, and the bottom surfaces of these limit blocks 3025 are on the same plane, which is convenient for placing the top shell on the middle shell.

[0193] When the electric heating device is working, the two electric heating tubes 3018 can generate heat at the same time to heat the air in the inner cavity of the heat-insulating shell. At the same time, the wind wheel 3017 rotates to allow the air in the inner cavity of the heat-insulating shell to flow and the temperature distribution to be more even. In this way, when the conveyor chain transports the carrier and the hollow cup second motor 3010 rotor on the carrier, the heating temperature of the hollow cup second motor 3010 rotor can be consistent, which helps to unify the heating time of the hollow cup second motor 3010 rotor and allow the glue on a batch of hollow cup second motor 3010 rotors to be cured after being heated by the electric heating device.

[0194] The carrier conveying mechanism is preferably mounted on the bottom shell of the heat-insulating housing, the middle shell surrounds the carrier conveying mechanism, and the carrier conveying mechanism also includes a carrier entry and exit seat and a gear transmission mechanism, wherein:

[0195] The chain plate conveyor belt 3015 is located inside the heat insulating shell, and includes a chain 3038 and a chain plate 3022. The chain 3038 is movably mounted on the heat insulating shell, and the chain plate 3022 is mounted on the chain 3038. A number of chain plates 3022 are fixedly mounted on the chain 3038. The chain plates 3022 are intended to keep the chain plate conveyor belt 3015 flat, so that when the chain plate conveyor belt 3015 is running, the carrier will not be violently shaken, causing the hollow cup motor rotor that needs to be baked to fall from the carrier.

[0196] The first motor 301 is preferably installed on the bottom shell of the thermal insulation shell, and the first motor shell of the first motor 301 is located outside the bottom shell of the thermal insulation shell, and the first motor 301 is connected to the chain 3038 through the gear transmission mechanism to drive the chain 3038 to move; the first motor 301 is preferably a deceleration first motor 301, and the first motor 301 is installed with an encoder 302 for obtaining the rotational speed of the first motor 301.

[0197] There are two carrier access seats, each of which is installed on the side wall of the heat-insulating shell, preferably on the side wall of the middle shell, and each of which is provided with a carrier access channel, and each of which is located above the chain plate conveyor belt 3015; if a carrier enters the heat-insulating shell from one of the carrier access channels, it will exit the heat-insulating shell from the other carrier access channel. The two carrier access channels are the first carrier access channel and the second carrier access channel.

[0198] Each of the carrier access channels is arc-shaped to guide the movement of the carrier. The carrier moves along the arc-shaped carrier access channel to the chain 3038 and leaves the chain 3038.

[0199] One end of each of the carrier entrance and exit channels is close to the chain-type conveyor belt 3015 and the other end is away from the chain-type conveyor belt 3015. The end of each of the carrier entrance and exit channels away from the chain-type conveyor belt 3015 is respectively arranged with a slideway 3045 for receiving the carrier so that the carrier can slide on the slideway 3045. The slideway 3045 is relatively smooth, which is necessary for facilitating the carrier to slide up and down. The end of each of the carrier entrance and exit channels close to the chain-type conveyor belt 3015 is through-connected from top to bottom, so that the carrier can slide onto the chain-type conveyor belt 3015 through the slideway 3045 of one of the carrier entrance and exit channels for transportation, and the carrier transported on the chain-type conveyor belt 3015 can leave the chain 3038 through the slideway 3045 of another of the carrier entrance and exit channels. Therefore, the arc-shaped carrier access channel has two arc-shaped inner side walls for guidance, and a part of the bottom wall has a slide 3045 to receive the carrier, and a part close to the chain plate conveyor belt 3015 is empty and through-through, and the inner side wall extends to the through-through part for guidance, so as to facilitate the carrier to move onto the chain plate conveyor belt 3015. Each carrier access channel can have at most two carriers at a time, one of which is on the slide 3045 of the carrier access channel, and the other is on the through-through part of the carrier access channel (the carrier at the through-through part has also fallen onto the chain plate conveyor belt 3015), so that it is convenient to squeeze the carriers one by one onto the chain plate conveyor belt 3015, or squeeze out of the slide of the carrier access channel to be transported away.

[0200] Before a carrier carrying a coreless motor rotor enters the heat-insulating housing, it can be placed on the track, and the carrier on the track can be moved to one of the slideways 3045 by a material-moving device, wherein the material-moving device includes a two-dimensional motion platform and a material-moving hand driven by the two-dimensional motion platform, and the two-dimensional motion platform drives the material-moving hand to move horizontally to move the frontmost carrier on the track to one of the slideways 3045; thereafter, the material-moving hand moves another carrier on the track to the slideway 3045, thereby squeezing the previous carrier on the slideway 3045 to the vertically connected part of the carrier access channel, and the vertically connected part corresponds to the chain plate conveyor belt 3015, and the carrier will just fall on the chain plate conveyor belt 3015. Since each of the carrier access channels is arc-shaped, the carrier can be guided along the arc-shaped carrier access channel, move to the vertically connected part of the carrier access channel, and just slide onto the chain plate conveyor belt 3015. The carrier also slides along the arc-shaped carrier access channel when leaving the chain plate conveyor belt 3015, and slides onto the slideway 3045 after leaving the chain plate conveyor belt 3015, and then can be taken away by the robot, or moved by the next carrier under inertia from the slideway 3045 and squeezed onto the conveyor belt for transportation. The electric heating device 30100 is arranged in the heat-insulating shell, so that the hollow cup motor rotor carried by the carrier can be heated when the carrier is transported.

[0201] Furthermore, the chain 3038 has a serpentine section, a rounded transition section and a straight connecting section, and the straight connecting section is connected to each end of the serpentine section through a rounded transition section. The serpentine section greatly expands the path of carrier baking, so that the glue of the hollow cup motor rotor carried on the carrier can be fully baked.

[0202] Further, the gear transmission mechanism includes a driving gear 305, a rotating shaft 3037, a driven gear 3012 and a transmission gear 3034, wherein the driving gear 305 is mounted on the output shaft of the first motor 301, the driven gear 3012 is meshed with the driving gear 305, the driven gear 3012 is mounted on the rotating shaft 3037, the rotating shaft 3037 is vertically arranged and rotatably mounted on the heat-insulating shell, the transmission gear 3034 is fixedly mounted on the rotating shaft 3037, and the transmission gear 3034 is meshed with one of the circular arc transition sections of the chain 3038. Therefore, by using a first motor 301 as a power source, in conjunction with a gear transmission mechanism, the entire plate chain conveyor belt can be driven to move to transport the carrier. Preferably, the present invention also includes a driven gear 3019 rotatably mounted on the heat-insulating shell and meshed with another circular arc transition section. The passive gear 3019 is driven by no power source and rotates by meshing with the chain 3038. The passive gear 3019 and the transmission gear 3034 are respectively meshed with a circular arc transition section. The circular arc transition section is equivalent to the transition point of the chain plate conveyor belt 3015. The transmission gear 3034 and the passive gear are arranged at the turning part. The transmission gear 3034 and the passive gear have the functions of supporting the chain plate conveyor belt 3015 and tightening the chain 3038. Preferably, the first motor 301 is a reduction first motor 301, with a gear box 303 at the front end and an encoder 302 at the rear end. The gear box 303 is fixedly installed with the mounting plate 304 through a flange, and the driving gear 305 is fixedly installed with the output shaft of the gear box 303. The mounting plate 304 is installed on the heat-insulating housing through the mounting column 3011.

[0203] After the first motor 301 is powered on, it drives the driving gear 305 to rotate. The rotation of the driving gear 305 drives the driven gear 3012 meshing with the driving gear 305 to rotate. The rotation of the driven gear 3012 drives the rotating shaft 3037 and the transmission gear 3034 to rotate. The rotation of the transmission gear 3034 drives the chain 3038 to move. The movement of the chain 3038 drives the entire chain conveyor belt 3015 to move.

[0204] Furthermore, it also includes a bearing mounting seat 3035 and a bearing 3033. The bearing mounting seat 3035 is fixedly mounted on the heat-insulating shell. The rotating shaft 3037 is mounted on the bearing mounting seat 3035 through the bearing 3033. The rotating shaft 3037 is provided with an external thread. The locking nut is connected to the external thread of the rotating shaft 3037 and locks the rotating shaft 3037 on the inner ring of the bearing 3033. The bearing 3033 ensures the normal rotation of the rotating shaft 3037.

[0205] Furthermore, there are multiple bearings 3033, and they are distributed along the vertical direction. The upper and lower ends of the bearing mounting seat 3035 are respectively provided with gaskets 3036. Each gasket 3036 is respectively fixed to the bearing mounting seat 3035 and abuts against one of the bearings 3033 to limit the position of the bearing 3033 at the upper end of the bearing 3033 seat and the bearing 3033 at the lower end of the bearing 3033 seat. Multiple bearings 3033 cooperate with the gaskets 3036 to ensure the reliability of the rotation of the rotating shaft 3037.

[0206] The rotating shaft 3037 , the transmission gear 3034 , the driven gear 3012 , the bearing 3033 , and the bearing mounting seat 3035 are coaxially mounted.

[0207] Furthermore, the heat-insulating shell is provided with limit bars 3023 at positions corresponding to both sides of the straight connecting section, and the limit bars 3023 are fixed to the heat-insulating shell through connecting blocks 3024 .

[0208] Furthermore, the heat-insulating outer shell is provided with inner limit blocks 3040 and outer limit blocks 3039 inside and outside each turning part of the serpentine section, respectively. The inner limit blocks 3040 and outer limit blocks 3039 are supported by first support blocks 3041 and second support blocks 3042, respectively. The first support blocks 3041 and the second support blocks 3042 are respectively fixedly mounted on the heat-insulating outer shell. The inner limit blocks 3040 and the outer limit blocks 3039 can make the chain 3038 bend into a serpentine shape and ensure the stability of the serpentine section, so that the chain 3038 can reliably transport the carrier.

[0209] The heat-insulating shell is provided with a mounting surface 3020 as a mounting base, for example, it can be used as a mounting base for parts such as a chain plate conveyor belt and a gear transmission mechanism.

[0210] The mounting surface 3020 is disposed as a whole inside the inner insulation layer 3032 of the bottom shell, and a temperature sensor 3014 is disposed at the center of the inner insulation layer 3032 of the bottom shell. The temperature sensor 3014 is fixedly mounted with the outer insulation layer 306 of the bottom shell through the mounting block 43. The temperature sensor 3014 can sense the temperature inside the present invention and display it through an external temperature display screen, so that the temperature inside the heat-insulating shell of the present invention can always be within the set temperature range. A plurality of second mounting columns 3047 are disposed on the reserved mounting plate 3013, and the second mounting columns 3047 pass through the bottom shell and are fixedly mounted on the mounting surface 3020. The plurality of second mounting columns 3047 are used to prop up the mounting surface 3020 so that the mounting surface 3020 will not press on the bottom shell. The reserved mounting plate 3013 is used to fix the bottom shell as a whole on other countertops.

[0211] Two notches 308 are provided on the side wall of the middle shell, corresponding to the first carrier access channel and the second carrier access channel, so as to facilitate the access of the carrier. The middle shell is arranged on the upper layer of the bottom shell, and the inner insulation layer 3032 of the bottom shell is slightly higher than the outer insulation layer 306 of the bottom shell, so that the middle shell and the bottom shell are conveniently sealed as a whole, and the insulation effect is better. A plurality of arc-shaped reserved mounting holes 3046 are provided on the outer insulation layer 307 of the middle shell, which are used to fix the middle shell to the table. The top shell is arranged as a whole above the middle shell and is fixed by a plurality of limit blocks 3025. The limit blocks 3025 can limit the top shell from horizontal movement and facilitate the overall opening.

[0212] Further, the chain tensioning mechanism includes a base, a moving block 30212, a cushion block 30211, a chain adjusting wheel 3021 and an adjusting bolt, wherein:

[0213] The base 30213 is provided with a horizontal slide groove 30218, and the bottom of the base 30213 is provided with a connection block, preferably the base 30213 and the connection block are integrally formed.

It has a first part 302121 and a second part 302122 that are integrally formed. Each end of the first part 302121 along the width direction of the slide groove 30218 respectively extends beyond the slide groove 30218, so that the first part 302121 of the movable block 30212 is placed on the top of the base; the second part 302122 of the movable block 30212 extends into the slide groove 30218 of the base so as to slide along the slide groove 30218. The slide groove 30218 serves as a guide groove for the movement of the movable block 30212, which can guide the movement of the second part 302122. A movable rod 30215 is provided at the bottom of the movable block 30212, and the movable block 30212 and the movable rod 30215 are preferably integrally formed.

[0215] The cushion block 30211 is installed on the first part 302121 of the moving block 30212 .

[0216] The center line of the chain adjusting wheel 3021 is vertically arranged, and the chain adjusting wheel 3021 is rotatably mounted on the cushion block 30211. The chain adjusting wheel 3021 is preferably located above the cushion block 30211. The chain adjusting wheel 3021 has external teeth evenly arranged circumferentially for fitting into the gap of the chain 3038. Then, the chain adjusting wheel 3021 is meshed with the chain 3038 and does not affect the normal movement of the chain 3038.

[0217] The adjusting bolt 30216 includes an integrally formed bolt head and a bolt rod 30214, the bolt rod 30214 includes a threaded portion 30217 and a cylindrical portion (the cylindrical portion is divided into a non-threaded portion 30217, that is, this portion is smooth), and the thread of the threaded portion 30217 protrudes relative to the cylindrical portion, the threaded portion 30217 is threadedly connected to the connecting block, and the cylindrical surface of the cylindrical portion is attached to the moving rod 30215. By turning the adjusting bolt 30216, the position of the chain adjusting wheel 3021 can be adjusted, so that the chain adjusting wheel 3021 is pressed on the chain 3038 to tighten the chain 3038, prevent the chain 3038 from becoming loose, and ensure the normal conveying work of the chain 3038.

[0218] Furthermore, the bolt rod 30214 is provided with at least two threaded portions 30217, and a cylindrical portion is provided between the two threaded portions 30217. Then, the adjusting bolt can drive the moving rod 30215 to move regardless of forward or reverse rotation, thereby adjusting the tightness of the chain 3038.

[0219] Further, the cushion block 30211 includes a fixed block and a connecting rod mounted on the fixed block, and the chain adjusting wheel 3021 is mounted on the connecting rod through a bearing 30219, so that the chain adjusting wheel 3021 can rotate. The cushion block 30211 keeps the chain adjusting wheel 3021 and the chain 3038 at the same height.

[0221] Furthermore, a hollow hole is provided on the first portion 302121 of the moving block 30212 , which can reduce the weight of the moving block 30212 and make it easier to turn the adjusting bolt to adjust the position of the chain adjusting wheel 3021 .

[0222] Furthermore, the moving rods 30215 are arranged in pairs and are arranged symmetrically front and back, and the pair of moving rods 30215 clamp the cylindrical portion, so that the contact between the thread and the moving rod 30215 is more reliable, preventing one moving rod 30215 from being unable to be pushed by the adjustment bolt after being worn, thereby affecting the normal adjustment of the chain adjustment wheel 3021. The pair of moving rods 30215 is arranged on the boss, so that the pair of moving rods 30215 and the boss together form an inverted U-shaped block.

[0223] By turning the adjusting bolt, the threaded portion 30217 of the bolt rod 30214 pushes the moving rod 30215 and the moving block 30212 to move forward and backward. The forward and backward movement of the moving block 30212 drives the chain adjusting wheel 3021 to move forward and backward, which is used to tighten or loosen the chain so that the chain is neither too tight nor too loose.

[0224] When the carrier conveying mechanism is working:

[0225] After the first motor 301 is powered on, it drives the driving gear 305 to rotate. The rotation of the driving gear 305 drives the driven gear 3012 meshing with the driving gear 305 to rotate. The rotation of the driven gear 3012 drives the rotating shaft 3037 and the transmission gear 3034 to rotate. The rotation of the transmission gear 3034 drives the chain 3038 to move. The movement of the chain 3038 drives the entire chain conveyor belt 3015 to move.

[0226] After the electric heating device in the heat-insulating shell works, the heat is isolated in the heat-insulating shell.

[0227] The carrier carrying the coreless motor rotor to be baked flows in from one of the carrier access channels and flows out from the other carrier access channel after being baked. The temperature sensor 3014 installed in the heat-insulating shell senses the real-time temperature in the oven and displays it on a display screen outside the heat-insulating shell. If the temperature is higher or lower than the required temperature, the desired baking effect can be achieved by adjusting the electric heating device or by adjusting the running speed of the chain plate conveyor belt 3015.

[0228] The present invention also includes an automatic sleeve discharging device, including a base frame 408, a vibration plate 401, a feed pipe 402, a mounting block 403, a rotary cylinder 407 and a rotating body 406, wherein:

[0229] The vibration plate 401 can be installed on the support frame, and the vibration plate 401 is used to transport the internal sleeve 405 out in an orderly manner.

[0230] The mounting block 403 and the rotary cylinder 407 are respectively mounted on the base frame 408, and the output shaft of the rotary cylinder 407 is arranged horizontally.

[0231] The mounting block 403 is provided with a horizontal through hole 4031, and the through hole 4031 is connected to the discharge port of the vibration plate 401 through the feed pipe 402, so that the sleeve 405 coming out of the vibration plate 401 can enter the through hole 4031 on the mounting block 403. The vibration plate 401 can adopt a conventional structure, which has a spiral slide, allowing the sleeve 405 to come out of the discharge port after passing through the spiral slide, and then enter the feed pipe 402 and the through hole 4031 on the mounting block 403.

[0232] The rotating body 406 is mounted on the output shaft of the rotating cylinder 407 to drive the rotating body 406 to rotate, and the rotation centerline of the rotating body 406 is perpendicular to the centerline of the through hole 4031 on the mounting block 403. The rotating cylinder 407 is preferably connected to the rotating body 406 via a rotating disk 4061, and the diameter of the rotating disk 4061 is larger than the diameter of the rotating body 406, so that the rotating disk 4061 is conveniently mounted on the output shaft of the rotating cylinder 407. The rotating disk 4061 is integrally formed with the rotating body 406, which is convenient for processing and manufacturing.

[0233] The rotating body 406 is provided with a blind hole 4062 at a position corresponding to the through hole 4031 of the mounting block 403, so that the sleeve 405 coming out of the through hole 4031 can enter the blind hole 4062. The inner diameter of the blind hole 4062 can be slightly larger than the inner diameter of the through hole 4031, so that the sleeve 405 can enter the blind hole 4062 conveniently. The blind hole 4062 is preferably coaxial with the through hole 4031 when in a horizontal position, so that the sleeve 405 can enter the blind hole 4062 conveniently from the through hole 4031. There is also a gap between the rotating body 406 and the mounting block 403, so that the sleeve 405 can be separated from the mounting block 403 after entering the blind hole 4062. The distance between the rotating body 406 and the mounting block 403 should be appropriate, and the depth of the blind hole 4062 should be appropriate and not too shallow to prevent the sleeve 405 from falling out of the blind hole 4062 when the rotating body 406 drives the sleeve 405 from horizontal to vertical. The depth of the blind hole 4062 should be smaller than the axial length of the sleeve 405, so that one end of the sleeve 405 is exposed in the blind hole 4062, which is convenient for the sleeve 405 to be clamped away by the robot.

[0234] Furthermore, a plurality of through holes are evenly arranged circumferentially on the rotating disk 4061 , and a bolt passes through each of the through holes so as to fix the rotating disk 4061 on the rotating cylinder 407 , thereby facilitating the disassembly and assembly of the rotating disk 4061 .

[0235] Furthermore, a flattening position 4063 is provided on the output shaft of the rotating body 406, and the blind hole 4062 is provided at the flattening position 4063 of the rotating body 406. Due to the existence of the flattening position 4063, the side surface of the rotating body 406 is composed of a plane and an outer cylindrical surface. The plane at the flattening position 4063 is preferably parallel to the center line of the blind hole 4062. When the rotating body 406 rotates to the horizontal state of the blind hole 4062, the flattening position 4063 can increase the distance between the rotating body 406 and the mounting block 403, so as to facilitate the frontmost sleeve 405 in the through hole 4031 to enter the blind hole 4062 of the rotating body 406. Then, when the rotating body 406 rotates again to allow the sleeve 405 to be vertical, the outer cylindrical surface of the rotating body 406 can shorten the distance between the rotating body 406 and the mounting block 403, thereby blocking the sleeve 405 in the through hole 4031 and preventing the sleeve 405 in the through hole 4031 from falling. Then, after the vertical sleeve 405 is taken away by the robot, the rotating body 406 rotates to a horizontal state of the blind hole 4062. At this time, due to the setting of the flat position 4063, the distance between the rotating body 406 and the mounting block 403 suddenly increases, so that the front end sleeve 405 has more time to maintain a relatively stable state to enter the blind hole 4062, and the sleeve 405 will not be unable to enter the blind hole 4062 due to the sudden alignment of the sleeve 405 and the blind hole 4062 and the alignment deviation caused by the sleeve 405 being in contact with the rotating body 406 all the time.

[0236] Furthermore, a detection hole connected to the blind hole 4062 is provided on the rotating body 406, and a laser sensor 404 is installed on the detection hole for detecting whether there is a sleeve 405 in the blind hole 4062. After the sleeve 405 is detected, the rotating cylinder 407 drives the rotating body 406 to rotate so that the sleeve 405 reaches a vertical position.

[0237] Furthermore, the center line of the blind hole 4062 is coplanar with the center line of the outer cylindrical surface of the rotating body 406 , so that the sleeve 405 is not easy to fall off during the rotation of the rotating body 406 , and the rotation angle of the rotating body 406 is easy to control.

[0238] The sleeve 405 of the utility model is transported to the discharge port through the spiral slide of the vibrating plate 401, flows out from the conveying pipe 402 in an orderly manner, passes through the through hole 4031 of the mounting block 403, and then enters the blind hole 4062 of the rotating body 406. The rotating cylinder 407 drives the rotating plate 4061 to rotate, and then drives the rotating body 406 to rotate. The rotation of the rotating body 406 drives the sleeve 405 to rotate, so that the sleeve 405 is changed from a horizontal placement to a vertical placement, which is convenient for the robot to grab, so that it can be applied to the production line, which helps to realize automated production and improve production efficiency.

The second driving cylinder is arranged on the slider of the cylinder 5092. The second clamping jaw 5091 is controlled to move up and down by the cylinder 5092, and the opening and closing are controlled by the second driving cylinder. Therefore, the second clamping jaw 5091 and the first clamping jaw 5081 can move relative to each other. After the first clamping jaw 5081 clamps the hollow cup motor rotor, the second clamping jaw 5091 can clamp the sleeve on the hollow cup motor rotor and then move upward relative to the first clamping jaw 5081, so that the sleeve on the hollow cup motor rotor can be pulled out and then placed on another plate.

[0241] The output shaft of the cylinder 5092 is parallel to the Z axis, and the second pneumatic clamp 509 is installed on the output shaft of the cylinder 5092, so the cylinder 5092 can drive the second pneumatic clamp 509 to move up and down.

The X-axis motion platform is a single-axis motion platform. The X-axis extends in the left-right direction, and the X-axis motion platform can drive the finished product placement plate 50102 to move in the left-right direction. The hollow cup motor rotor with the sleeve removed is transferred by the first pneumatic clamp 508 and placed on the finished product placement plate 50102.

[0243] The X-axis motion platform is arranged on the desktop through a mounting frame 5011, and the installation is flexible.

[0244] The X-axis, Y-axis and Z-axis are three axes of a Cartesian coordinate system.

[0245] Furthermore, a track 111 for arranging materials is included so that the first pneumatic gripper can grip the materials on the track 111. The materials (hollow cup motor rotor with a sleeve on the rotor shaft) are arranged on the track 111 and can be gripped and taken away by the first pneumatic gripper 508.

[0246] Furthermore, a finished product placement plate placement block 5010 is installed on the X-axis motion platform, and the finished product placement plate placement block 5010 is installed with the finished product placement plate 50102 through a fixing block 50101.

The Y-axis motor 502 is connected to the Y-axis lead screw, and the Y-axis transmission nut is installed on the Y-axis lead screw, and the Y-axis transmission nut is mounted on the Y-axis slide rail 5031. The Y-axis motor 502 is a reduction motor with a Y-axis reduction box, and a Y-axis encoder 5021 is connected to the motor shaft of the Y-axis motor 502 to realize closed-loop control. The Y-axis gear box 5022 is fixedly mounted with the Y-axis bracket 503 through the Y-axis flange.

[0248] Further, the Z-axis motion platform includes a Z-axis bracket, a Z-axis motor, a Z-axis lead screw 504 and a Z-axis transmission nut 5041, wherein the Z-axis bracket is mounted on the Y-axis transmission nut, the Z-axis motor and the Z-axis lead screw 504 are respectively mounted on the Z-axis bracket, the Z-axis motor is connected to the Z-axis lead screw 504, the Z-axis transmission nut 5041 is worn on the Z-axis lead screw 504, and the Z-axis transmission nut 5041 is mounted on the cylinder 5092 and the first pneumatic clamp 508 through a mounting plate 507.

[0249] Furthermore, a sensing sheet 506 is installed on the Z-axis transmission nut 5041, and a photoelectric sensor 505 for obtaining the position of the sensing sheet 506 is provided on the support frame 501. The position of the Z-axis transmission nut 5041 can be known through the sensing sheet 506. Since there are many parts installed on the Z-axis transmission nut 5041, it is necessary to monitor the position to facilitate debugging and control, and prevent the movement stroke from being too large to cause damage to the instrument.

[0250] The photoelectric sensors 505 are arranged in three positions from top to bottom, respectively, for obtaining the upper limit position, the initial position and the lower limit position of the sensing sheet 506. The three photoelectric sensors 505 can better ensure the installation, because if only one photoelectric sensor 505 is provided, in case of machine parameter setting error or failure, the Z-axis transmission nut 5041 may move to the limit position as a whole, and a collision may occur, resulting in damage to the instrument.

[0252] The working process of the utility model is as follows:

[0253] The Y-axis transmission nut of the Y-axis motion platform drives the Z-axis motion platform to move horizontally back and forth, and at the same time, the first pneumatic clamp 508 and the second pneumatic clamp 509 also move horizontally.

[0256] The cylinder 5092 controls the second pneumatic gripper 509 to move up and return to the previous position.

There is a circle of positioning pins 6010 on the tooling 608, and there is also a circle of positioning holes at the bottom of the rotor frame 609 of the coreless motor rotor. The size and position distribution of the positioning pins 6010 should correspond to the positioning holes at the bottom of the rotor frame 609 of the coreless motor rotor. In this way, after the rotor frame 609 is placed on the positioning pins 6010, it is convenient to accurately align and position the rotor frame 609, and prevent the rotor frame 609 from rotating and shaking in the circumferential direction and affecting normal production and processing.

[0264] The tooling 608 is provided with a vertical channel for positioning the rotor shaft of the coreless motor rotor. After the rotor shaft is positioned, a circle of positioning holes at the bottom of the rotor frame and a circle of positioning pins 6010 on the tooling 608 are on the same distribution circle, which facilitates the insertion of the positioning pins 6010 into the positioning holes after the rotor frame is rotated. The rotor frame 609 is mounted on the rotor shaft, and a section of the rotor shaft is provided above and below the rotor frame 609. A section of the rotor shaft below the rotor frame 609 is first extended into the channel, and then the rotor frame 609 is placed on the positioning pins 6010. The channel is preferably a V-shaped groove, and the two groove walls of the V-shaped groove can clamp the rotor shaft of the coreless motor, which is convenient for centering the rotor shaft and aligning the rotor frame 609.

[0265] Furthermore, there are multiple bearings and they are arranged on the inner wall of the fixed sleeve 6014 from top to bottom, which can make the rotation of the rotating shaft 604 more stable.

[0266] Furthermore, the utility model also includes a rotating shaft locking nut 6011;

[0267] The rotating shaft 604 is provided with an external thread, and the rotating shaft locking nut 6011 is threadedly connected to the external thread of the rotating shaft 604 and locks the rotating shaft 604 on the inner ring of the bearing to prevent the rotating shaft 604 from shaking up and down.

[0268] Furthermore, the output shaft of the motor 601 is connected to an encoder, and the rotation angle of the output shaft of the motor 601 can be accurately known through the encoder.

[0269] The rotating shaft 604 is provided with a sensing sheet 606, and the mounting frame is provided with a photoelectric sensor 607 for detecting the position of the sensing sheet 606.

[0271] When installing the rotor frame 609 on the tooling 608, an automated device can be used. The automated device includes a lifting mechanism and a pneumatic clamp and a rotating mechanism installed on the lifting mechanism. The pneumatic clamp clamps the rotor frame 609. The clamping force on the rotor frame 609 should be appropriate, not too large or too small. The rotating mechanism drives the pneumatic clamp to rotate, and the lifting mechanism drives the rotating mechanism and the pneumatic clamp to rise and fall together. The pneumatic clamp moves the rotor frame 609 downward while rotating to allow the positioning pin 6010 to be inserted into the positioning hole at the bottom of the rotor frame 609 to achieve alignment. After that, the pneumatic clamp will have relative rotation and relative sliding with the rotor frame 609, and the installation of the rotor frame 609 is completed.

[0272] The motor 601 rotates after being energized, driving the rotating shaft 604 to rotate. The rotating shaft 604 rotates with the induction sheet 606 and the tooling 608, which drives the rotor frame 609 to rotate, making it convenient for other automated equipment to apply a circle of glue on the rotor frame 609, install a commutator on the rotor frame 609, and spot weld multiple tin points circumferentially on the commutator on the rotor frame 609 to form a circle of tin points.

[0276] The pneumatic clamp includes a drive cylinder 7052 and a clamping claw 705 installed on the drive cylinder 7052, which is used to clamp the vertical wire cup; the drive cylinder 7052 is used to drive the clamping claw 705 to open and close, and can clamp the wire cup when closed, and can release the wire cup when opened, so that other manipulators can take away the wire cup pressed into the rotor frame.

[0277] The slide rail 7041 is vertically mounted on the base 706 .

[0278] The slider 7033 is installed on the slide rail 7041, and the slider 7033 can move up and down along the slide rail 7041 to maintain stability.

[0279] The lower end of the output shaft 7011 of the cylinder 701 is fixedly connected to the slider 7033 to drive the slider 7033 to move up and down.

[0280] The die 7032 is mounted on the slider 7033 and is located above the clamping claw 705, so as to press the rotor frame of the coreless motor into the wire cup clamped by the clamping claw 705. The rotor frame mounted on the rotor shaft can be placed on the wire cup in advance by other manipulators, and then the die 7032 moves downward to contact the rotor shaft, so that the rotor frame can be pressed into the wire cup. Since the cylinder 701 controls the movement of the die 7032, the force and stroke can be automatically controlled.

[0281] Further, the slider 7033 is fixedly connected to the output shaft 7011 of the cylinder 701 through the fixing block 703 and the connecting column. The fixing block 703 is installed on the slider 7033, and a vertical connecting column is installed on the fixing block 703, and the connecting column is installed on the output shaft of the cylinder.

A plurality of reinforcing ribs are arranged between the mounting plate 7031 and the slider 7033 to improve the installation strength of the slider 7033.

[0284] Furthermore, there are multiple slide rails 7041, and the slider 7033 is installed on these slide rails 7041, so that the slider 7033 can move more smoothly.

[0285] Furthermore, the base 706 is provided with a through opening 7042, and the pneumatic clamp is horizontally installed at the opening 7042. The setting of the opening 7042 can save installation space, so that the pneumatic clamp can move backward relative to the die 7032 as a whole, so that the clamping claw 705 and the die 7032 can maintain a relatively appropriate spatial position. The opening 7042 is preferably further provided with a horizontal connecting plate 7051, and the clamping claw 705 is provided on the driving cylinder 7052, and the driving cylinder 7052 is fixedly installed on the connecting plate 7051, and the connecting plate 7051 is installed at the opening 7042 of the base 706, and the clamping claw 705 extends from the opening 7042 to clamp the wire cup.

[0286] Furthermore, the pressing die 7032 can be detachably mounted on the slider 7033 , so that the pressing die 7032 can be replaced according to different pressing objects. For example, if the commutator needs to be pressed into the rotor frame, a different pressing die 7032 can be replaced.

[0287] During operation, the output shaft 7011 of the cylinder 701 moves downward, and the output shaft 7011 of the cylinder 701 pushes the connecting column, so that the slider 7033 moves downward on the slide rail 7041, and then drives the pressing die 7032 to move downward, pressing the rotor frame to be pressed into the wire cup.

[0288] The wire coiling mechanism of the present invention comprises a rotating base 80200 and a wire pressing device 80100, wherein:

The conveying mechanism can be a conveyor belt or a manipulator. If it is a conveyor belt, the conveyor belt is perpendicular to the guide rail 8048, and the front carrier 8015 is transported to the guide rail 8048 along a direction perpendicular to the guide rail 8048. Since the front carrier 8015 is blocked by the blocking strip 8047, the rear carriers 8015 are lined up on the conveying mechanism, waiting for the front carrier 8015 to be sent away before they can be transported to the guide rail 8048 in order.

[0291] The motor 8037 and the cylinder 8018 are respectively mounted on the mounting platform 8035 . The rotating shaft 8054 is vertically arranged and rotatably mounted on the mounting platform 8035 . The motor 8037 is connected to the rotating shaft 8054 .

[0292] The carrier positioning block 8042 is installed at the top end of the rotating shaft 8054, and the carrier positioning block 8042 has an inner cavity, and the carrier positioning block 8042 includes a photoelectric sensor 80421, a side connecting block 80422 and a bottom block 80423 for receiving the carrier 8015, the side connecting block 80422 connects the photoelectric sensor 80421 and the bottom block 80423, and the bottom block 80423 is provided with a through hole serving as a moving channel for the top rod.

[0293] The material shifting device includes a material shifting block 808 and a multi-axis motion platform, the material shifting block 808 is installed on the multi-axis motion platform, and a material shifting groove is provided on the material shifting block 808 so as to shift the carrier 8015 on the guide rail 8048, so that the carrier 8015 can extend into the inner cavity of the carrier positioning block 8042 and be received by the bottom block 80423 of the carrier positioning block 8042, then the carrier 8015 can be placed on the bottom block 80423 of the carrier positioning block 8042, and preferably the base 8044 of the carrier 8015 enters the inner cavity of the carrier positioning block 8042.

[0294] There are many structural forms of the carrier 8015, as long as it can carry the hollow cup motor rotor. After the hollow cup motor rotor composed of the coil, rotor frame and commutator 8045 is placed on the carrier 8015, the soldering device above the rotating base 80200 can perform welding operations on the hollow cup motor rotor.

[0295] The rotating shaft 8054 has a through hole that passes through from top to bottom. The rotating shaft 8054 and the push rod 8056 are coaxially arranged, and the push rod 8056 is movably installed inside the rotating shaft 8054, that is, the rotating shaft 8054 and the push rod 8056 are not fixed together, but are independent of each other, and the two can rotate and move relative to each other. The cylinder 8018 is fixedly connected to the lower end of the push rod 8056 to drive the push rod 8056 to move up and down, so that when the push rod 8056 moves upward, the top end of the push rod 8056 cooperates with the photoelectric sensor 80421 of the carrier positioning block 8042 to clamp the carrier 8015, and when the push rod 8056 moves downward, the clamping of the carrier 8015 is released. The lower end of the push rod 8056 preferably exceeds the lower end of the rotating shaft 8054, so that the cylinder 8018 is connected to the push rod 8056. When the push rod 8056 moves upward, the carrier 8015 is pressed against the photoelectric sensor 80421, so that the carrier 8015 cannot move. In this way, when the rotating shaft 8054 drives the carrier positioning block 8042 and the carrier 8015 to rotate together, the carrier 8015 will not shift, thereby not affecting the soldering work of the soldering device above the rotating base 80200 on the hollow cup motor rotor.

[0296] Furthermore, the cylinder 8018 has a push rod 8019, which is connected to the push rod 8056 through a push rod connector 8057. The push rod 8019 is pushed upward to drive the push rod 8056 to move upward. The cylinder 8018 is fixedly mounted on the mounting platform 8035 through a mounting block.

[0297] Furthermore, the photoelectric sensor 80421 is provided with a guide groove 204211, and the guide groove 204211 is parallel to the guide rail 8048, so that the carrier 8015 moves along the guide groove 204211 to the carrier positioning block 8042. If a portion of the carrier 8015 extends upward beyond the photoelectric sensor 80421, the guide groove 204211 can well adapt to the shape of the carrier 8015, so that the carrier 8015 can still enter the inner cavity of the carrier positioning block 8042.

[0298] Furthermore, the carrier 8015 is provided with two mutually parallel first guide surfaces, and correspondingly, the inner wall of the carrier positioning block 8042 is also provided with two mutually parallel second guide surfaces, and each of the second guide surfaces is respectively fitted with one of the first guide surfaces. If the carrier 8015 and the carrier positioning block 8042 have cylindrical structures, the first guide surface and the second guide surface are respectively formed into flat structures, and the two guide surfaces can make the flat positions fit together well, and can also prevent the carrier 8015 from having rotational displacement when the carrier positioning block 8042 drives the carrier 8015 to rotate, thereby affecting the normal welding of the hollow cup motor rotor by the soldering device.

[0299] Further, the motor 8037 is connected to the rotating shaft 8054 through a gear mechanism, and the gear mechanism includes a driving gear 8016 and a driven gear 8017, and the driving gear 8016 and the driven gear 8017 are meshed with each other, so the driving gear 8016 is installed on the output shaft of the motor 8037, and the driven gear 8017 is fixedly installed on the rotating shaft 8054. The driven gear 8017 drives the rotating shaft 8054 to rotate, and the rotating shaft 8054 drives the carrier positioning block 8042 to rotate, and the carrier positioning block 8042 drives the carrier 8015 to rotate, and the carrier 8015 drives the thread head 8014 on the carrier 8015 and the hollow cup motor rotor to rotate.

[0300] Furthermore, the multi-axis moving platform is an XY-axis motion platform, which is used to drive the material shifting block 808 to move horizontally in a direction parallel to the guide rail and in a direction perpendicular to the guide rail, wherein the X-axis of the XY-axis motion platform is parallel to the guide rail 8048, and the Y-axis is perpendicular to the guide rail 8048. When the material shifting block 808 moves in a direction perpendicular to the guide rail 8048, the material shifting groove can be stuck on the carrier 8015. When it moves in a direction parallel to the guide rail 8048, the carrier 8015 can be moved, so that the carrier 8015 can move along the length direction of the guide rail 8048 to extend into the inner cavity of the carrier positioning block 8042.

[0301] The multi-axis motion platform includes a first cylinder 806, a slider, a mounting frame 22, a second slider 8020, and a second cylinder 807.

At the same time, the first cylinder 806 is fixedly installed on the second slider 8020, and the second slider 8020 is pushed by the second cylinder 807, and the second cylinder 807 is fixedly installed on the mounting platform 8035. The second cylinder 807 pushes the second slider 8020 to move left and right, and the first cylinder 806 fixedly installed with the second slider 8020 moves left and right. At the same time, it drives the material shifting block 808 to move left and right, so that the material shifting block 808 can achieve the functions of moving forward, right, backward, and left, and the carrier 8015 carrying the wire head 8014 and the rotor frame that have not yet undergone the welding process is moved to the bottom of the soldering gun for welding operations.

[0302] Furthermore, the rotating base 80200 further includes an encoder, a photoelectric sensor 8040 and a sensing sheet 8039. The encoder is connected to the output shaft of the motor 8037. The photoelectric sensor 8040 and the sensing sheet 8039 are respectively mounted on the mounting platform 8035 and the rotating shaft 8054 to obtain the rotation information of the rotating shaft 8054. The rotation angle of the rotating shaft 8054 can be obtained through the encoder, and the initial position of the rotating shaft 8054 can be obtained by the cooperation of the photoelectric sensor 8040 and the sensing sheet 8039. The encoder, the photoelectric sensor 8040 and the sensing sheet 8039 can be used to obtain the rotation position of the rotating shaft 8054.

[0303] Furthermore, the rotating shaft 8054 is mounted on the mounting platform 8035 via a bearing, an outer wall of the rotating shaft 8054 is provided with an external thread, and a locking nut 8053 is connected to the external thread of the rotating shaft 8054, thereby locking the rotating shaft 8054 on the inner ring of the bearing to prevent axial shaking of the rotating shaft 8054 when rotating. The rotating shaft 8054 is mounted on the mounting platform 8035 via two bearings, the two bearings are a first bearing 8051 and a second bearing 8055, the first bearing 8051 is above the second bearing 8055, and the locking nut 8053 locks the rotating shaft 8054 on the inner ring of the first bearing 8051.

[0304] Furthermore, a receiving hole is provided on the guide rail 8048, and the carrier positioning block 8042 is located at the receiving hole. Then, the carrier positioning block 8042 divides the guide rail 8048 into two sections, one section is used to allow the carrier 8015 to enter the carrier positioning block 8042, and the other section is used to allow the carrier 8015 that has completed the welding process to leave the carrier positioning block 8042 and move to the next process.

[0305] Furthermore, the plane of the bottom block 80423 used to support the carrier 8015 is coplanar with the plane of the guide rail 8048 used to support the carrier 8015 , which facilitates the carrier 8015 on the guide rail 8048 to enter and exit the carrier positioning block 8042 .

[0306] Furthermore, the guide groove 204211 on the photoelectric sensor 80421 is arranged throughout the entire length, and there are two material shifting grooves on the material shifting block 808, and the two material shifting grooves are arranged along the length direction of the guide rail 8048, so as to be used to shift one of the carriers 8015 into the carrier positioning block 8042 and shift the other carrier 8015 out of the carrier positioning block 8042 at the same time.

[0307] The base rotating device is integrally arranged below the soldering gun of the soldering device. The motor 8037 is preferably a reduction motor 8037, which has a gear box 8036. The driving gear 8016 is fixedly mounted on the output shaft of the gear box 8036. The motor 8037 is connected to an encoder to form a closed-loop control. The gear box 8036 is fixedly mounted on the flange 8041 and fixedly mounted with the mounting platform 8035 through the flange 8041. The rotating shaft 8054 is fixedly mounted on the mounting platform 8035 through a bearing. A plurality of support columns 34 are respectively arranged around the mounting platform 8035 for mounting with the table of the production line.

[0308] A locking nut 8053 is arranged above the induction sheet 8039, and a bearing and a bearing support ring 8050 are arranged at the upper end of the locking nut 8053. The bearing and the bearing support ring 8050 are arranged inside the bearing mounting seat 8052, and the bearing mounting seat 8052 is installed on the mounting platform 8035. The carrier positioning block 8042 is arranged at the upper end of the rotating shaft 8054 and is fixedly installed with the rotating shaft 8054. The thread head 8014 and the rotor of the hollow cup motor 8037 are arranged on the carrier 8015 at the same time. The outer side of the rotor shaft 8043 of the hollow cup motor 8037 is sleeved with a sleeve 8013. The sleeve 8013 is used to protect the commutator 8045. In the case of high-temperature welding, the tin beads and rosin will not splash into the slots of the commutator 8045 to prevent the generation of defective products.

[0309] The wire pressing device 80100 includes a pressure head driving cylinder 802 and a pressure head 805, wherein the pressure head driving cylinder 802 is installed on the mounting platform 8035 or the base 801, and the pressure head 805 is connected to the pressure head driving cylinder 802 to drive the pressure head 805 to move horizontally, so that the pressure head 805 presses down the standing wire head on the wire cup of the hollow cup motor rotor on the carrier (initially, part of the wire head on the wire cup is upright, and another part is relative to the upright position, with a certain deflection angle inward or outward, and needs to be pressed down to a roughly horizontal position, close to the commutator to achieve welding of the wire head and the commutator). The pressure head driving cylinder 802 is preferably a slider cylinder, and the slider 803 thereof is connected to a mounting block 804, and the pressure head 805 is preferably connected through the mounting block. Two wire pressing devices 80100 can be set at the same time, and are arranged symmetrically on both sides of the wire head 8014, which can improve work efficiency.

[0310] The end face of one end of the pressing head 805 used to contact the thread end is an arc surface 8052, and arc transition angles are respectively provided on the upper edge and the lower edge of the arc surface 8052, namely an upper arc transition angle 8053 and a lower arc transition angle 8051. The upper arc transition angle 8053 can contact the thread end 80141 that is standing and deflected outward at a certain angle, and the lower arc transition angle 8051 can contact the thread end 80141 that is standing and deflected inward at a certain angle. Then the pressing head 805 moves horizontally to press the thread end 80141 to a roughly horizontal state.

[0311] The working process of the winding mechanism is as follows:

[0312] 1) The first cylinder 806 pushes the first slider 80381 forward, driving the material-dispensing block 808 installed with the first slider 80381 to move to the left, and the material-dispensing groove on the material-dispensing block 808 is stuck on the carrier 8015. Then, the second cylinder 807 pushes the second slider 8020 forward, and the movement of the second slider 8020 drives the material-dispensing block 808 forward, driving the carrier 8015 to move forward as well. The flat part of the carrier 8015 is loaded into the carrier positioning block 8042, and at the same time, the cylinder pushes the push rod 8019 upward, and the push rod 8019 pushes the push rod 8056 through the connector 8057, so that the push rod 8056 moves upward and supports the carrier 8015. The push rod 8056 and the photoelectric sensor 80421 of the carrier positioning block 8042 clamp the carrier 8015 together, so that the carrier 8015 is fixed in the carrier positioning block 8042. At the same time, the material-selecting block 808 retreats to the right and then moves back to the initial position.

[0313] 2) The pressing heads 805 of the left and right wire pressing devices 80100 move horizontally at the same time, pressing the two wire ends 80141 on the wire end 8014 down to a position close to the commutator at the same time.

[0314] 3) A pair of soldering guns of the soldering device above the rotating base first move downwards, and after the soldering guns are powered on, two wire ends 80141 of the wire ends 8014 are welded together with the commutator 8045 (there are already solder joints on the commutator 8045). After welding, the pair of soldering guns of the soldering device above the rotating base 80200 are retracted upwards.

[0315] 4) The motor 8037 drives the driving gear 8016 to rotate, and then drives the driven gear 8017 meshing with the driving gear 8016 to rotate. The rotation of the driven gear 8017 drives the rotating shaft 8054 fixedly mounted on the driven gear 8017 to rotate. The rotation of the rotating shaft 8054 drives the sensing sheet 8039 mounted on the rotating shaft 8054 to rotate a set angle, and at the same time drives the carrier positioning block 8042 to rotate a set angle. The carrier positioning block 8042 drives the carrier 8015 to rotate a set angle. The set angle of rotation of the rotating shaft 8054 is determined by the sensing sheet 8039 and the photoelectric sensor 8040.

[0316] 5) If the number of wire ends 80141 is even, repeat the above steps 2), 3) and 4) until all wire ends 80141 are welded to the commutator 8045.

[0317] If the number of wire ends 80141 is odd, when there is only one unsoldered wire end 80141, the pressure head on one side moves next time, and the soldering gun on one side moves downward to weld the last wire end 80141 of the wire ends 8014 to the commutator 8045. In this way, the welding of all wire ends 80141 and the commutator 8045 is completed.

[0318] After welding is completed, the push rod 8019 falls back, pulling the push rod 8056 back, and the push rod 8056 releases the clamping of the carrier 8015, so that the material shifting block 808 can smoothly shift the carrier 8015 from the carrier positioning block 8042, allowing the carrier positioning block 8042 to enter the next process with the carrier and the hollow cup motor rotor carried on the carrier.

[0319] The rotary pressing device of the present invention comprises a mounting seat, a motor 901, a cylinder 907, a transfer block 9015, a first bearing 9016, a sliding sleeve 9017, a clamping jaw 9019 and a clamping jaw mounting frame 9018, wherein:

[0320] The cylinder 907 and the motor 901 are respectively mounted on the mounting seat, the adapter block 9015 is mounted on the output shaft of the cylinder 907 to drive the adapter block 9015 to move up and down, the output shaft 902 of the motor is connected to the vertically arranged rotating shaft 9021 to drive the rotating shaft 9021 to rotate, and the output shaft 902 of the motor is preferably connected to the rotating shaft 9021 through a coupling 903. The mounting seat includes a bracket 904 and a mounting plate 9013 fixedly connected to the bracket 904, the motor 901 is mounted on the bracket 904, and the bracket 904 and the cylinder 907 are fixedly mounted on the mounting plate 9013 through a first connecting block 9014 and a second connecting block 9027, respectively.

[0321] The sliding sleeve 9017 is installed on the adapter block 9015 through the first bearing 9016, and the center line of the sliding sleeve 9017 is vertical, so the sliding sleeve 9017 can rotate relative to the adapter block 9015 and move up and down under the drive of the cylinder 907 and the adapter block 9015. The sliding sleeve 9017 is movably sleeved on the rotating shaft 9021 so as to move up and down relative to the rotating shaft 9021.

[0322] The clamping jaw mounting frame 9018 is fixedly mounted on the rotating shaft 9021 , and the rotation of the rotating shaft 9021 can drive the clamping jaw mounting frame 9018 to rotate together.

[0323] The clamping jaw 9019 includes a pair of clamping fingers, each of which is hinged to the clamping jaw mounting frame 9018 via a horizontal hinge shaft. Each clamping finger can rotate around the corresponding hinge shaft, so that the two clamping fingers can close together to clamp an object when they are close to each other, or can release the object when they are away from each other.

[0324] The sliding sleeve 9017 is provided with notches at positions corresponding to each of the clamping fingers, and the upper end of each of the clamping fingers is respectively inserted into one of the notches, so that the sliding sleeve 9017 can also move on the clamping fingers when it moves downward along the axial direction of the rotating shaft 9021, thereby facilitating the lower ends of the two clamping fingers to approach each other to clamp the commutator 9026 of the hollow cup motor 901. The clamping force of the two clamping fingers should be appropriate and not too large, allowing the clamping jaws 9019 and the commutator 9026 to rotate relative to each other and slide up and down relative to each other, and facilitating the rotating shaft 9021 to drive the commutator 9026 clamped on the clamping jaws 9019 to rotate to align with the rotor frame 9025 for assembly. Since the notch groove and the clamping finger extend into the notch groove, and the rotor mounting frame is fixed on the rotating shaft 9021, the rotating shaft 9021 can drive the two clamping fingers to rotate when rotating, and the two clamping fingers can also drive the sliding sleeve 9017 to rotate together, and the setting of the sliding sleeve 9017 does not affect the normal rotation of the clamping jaw 9019. The clamping jaw 9019 can be clamped or opened by the linear motion of the sliding sleeve 9017 along the axial direction of the rotating shaft 9021, that is, the linear motion of the sliding sleeve 9017 can be converted into the rotational motion of the clamping finger around the hinge axis to realize the movement of the clamping jaw 9019. After the sliding sleeve 9017 moves upward, the clamping finger can return to its original position under its own gravity, or a return spring can be installed between the two clamping fingers, so that after the sliding sleeve 9017 enters the notch groove of the clamping finger, the clamping finger can always be attached to the sliding sleeve 9017.

[0325] The push rod 908 of the cylinder 907 is connected to the adapter block 9015 through the fixed block 909, the moving block 9010, etc. The push rod 908 of the cylinder 907 passes through the central hole of the second connecting block 9027 and is fixedly connected to the fixed block 909.

[0328] Furthermore, an encoder is connected to the output shaft 902 of the motor; a sensing sheet 906 is provided on the rotating shaft 9021, and a photoelectric sensor 905 for detecting the position of the sensing sheet 906 is fixedly installed on the mounting seat. The initial position of the sensing sheet 906 can be known through the photoelectric sensor 905, and then the rotation angle of the rotating shaft 9021 can be known in conjunction with the encoder, and then the rotation angle of the clamping jaw 9019 can be known, which is convenient for debugging and control.

[0329] Furthermore, a mounting block is fixed on the mounting seat, and a plurality of second bearings 9022 are sequentially mounted in the mounting block from top to bottom.

[0330] Furthermore, it also includes a rotating shaft locking nut 9023, and the rotating shaft 9021 is provided with an external thread. The rotating shaft locking nut 9023 is threadedly connected to the rotating shaft 9021 and locks the rotating shaft 9021 on the inner ring of the second bearing 9022, thereby effectively reducing the jitter of the rotating shaft 9021 during rotation.

[0331] Furthermore, it also includes a two-dimensional motion platform, on which the mounting seat is connected to drive the mounting seat to move up and down and in the horizontal direction.

[0332] Furthermore, it also includes a tool 9029 for placing the rotor frame 9025, and the tool 9029 is provided with a hole for accommodating the rotor shaft.

[0333] The output shaft of the cylinder 907 pushes the push rod 908 downward, driving the fixed block 909 downward, the fixed block 909 drives the moving block 9010 and the slider 9011 to move downward along the slide rail 9012, the moving block 9010 moves downward and drives the adapter block 9015 downward, the adapter block 9015 moves downward and drives the sliding sleeve 9017 to move downward, when the sliding sleeve 9017 moves downward, the notch moves downward along the clamping jaw 9019, so that the lower ends of the two clamping fingers are retracted to clamp the commutator 9026.

[0334] After the motor 901 is powered on, the output shaft drives the rotating shaft 9021 to rotate. The rotation of the rotating shaft 9021 drives the rotation of the clamp mounting frame 9018, the clamp 9019, the mold 9020 and the sliding sleeve 9017, so that a circle of side bosses 90261 of the commutator 9026 and a circle of grooves 90251 of the rotor frame 9025 can be aligned in place.

[0335] Specifically, the method for automatically assembling the commutator 9026 and the rotor frame 9025 of the coreless cup motor 901 rotor by using the rotary pressing device comprises the following steps:

[0337] 2) The two-dimensional motion platform drives the mounting seat and the clamping jaw 9019 to move, so that the clamping jaw 9019 moves to the commutator 9026, and the cylinder 907 drives the sliding sleeve 9017 to move downward, and the sliding sleeve 9017 drives the two clamping fingers of the clamping jaw 9019 to close to clamp the commutator 9026, wherein the clamping force of the two clamping fingers on the commutator 9026 allows the two clamping fingers to rotate relative to the commutator 9026 and move up and down relative to the steering gear;

[0338] 3) The two-dimensional motion platform drives the mounting seat, the clamping jaws 9019 and the commutator 9026 to move, so that the commutator 9026 moves to the top of the rotor frame 9025, and then the two-dimensional motion platform drives the commutator 9026 to move downward, so that the commutator 9026 is inserted into the rotor shaft 9028 and moves downward along the axial direction of the rotor shaft 9028; wherein, a plurality of grooves 90251 are evenly arranged on the top surface of the rotor seat in the circumferential direction, and the commutator 9026 has a plurality of side bosses 90261, and each side boss 90261 is used to enter one of the grooves 90251;

[0339] 4) When the commutator 9026 moves axially along the rotor shaft 9028 to a set distance from the rotor frame 9025 (since the length of the rotor shaft 9028 is known, the distance that the two-dimensional motion platform drives the commutator 9026 to move up and down can also be known, so the set distance between the commutator 9026 and the rotor frame 9025 can be accurately controlled, or other laser ranging sensors can be used to sense the position of the commutator 9026 so that the two reach the set distance), the motor 901 drives the clamping jaw 9019 to rotate, so that the clamping jaw 9019 moves downward with the commutator 9026 and also rotates with the commutator 9026. During the process of rotation and downward movement of the commutator 9026, the side boss 90261 of the commutator 9026 enters the groove 90251 of the rotor frame 9025.

[0340] 5) The motor 901 continues to rotate, so that the clamping jaws 9019 clamp the commutator 9026 and rotate, and the commutator 9026 rotates with the rotor frame 9025, so that the positioning hole at the bottom of the rotor frame 9025 is aligned with the positioning pin 90291 on the tooling 9029, and the positioning pin 90291 falls into the positioning hole, so that the rotor frame 9025 is positioned on the tooling 9029. Since the clamping force is appropriate and not too large, if the rotor frame 9025 falls on the positioning pin 90291, the motor 901 continues to rotate, and the clamping jaws 9019 will rotate relative to the commutator 9026, and the motor 901 will not be damaged. If the two-dimensional motion platform continues to move downward with the mounting seat, the clamping jaws 9019 will also move relative to the commutator 9026, and the two-dimensional motion platform will not be damaged.

[0341] After the side boss 90261 of the commutator 9026 is aligned and installed in the groove 90251 of the rotor frame 9025, the side boss 90261 does not enter the groove 90251 to a great depth because the groove 90251 needs to clamp the side boss 90261 and the force of the clamping jaws 9019 to clamp the commutator 9026 is not strong. Subsequently, the commutator 9026 will be pressed downward by the die of the press-fitting device to further press the side boss 90261 of the commutator 9026 downward to the set position. After the rotor frame 9025 is initially positioned on the jig, the rotor frame 9025 and the commutator 9026 will not shift in the subsequent processing steps to affect normal production.

If the number of carriers 10023 on the first conveyor belt 10081 is relatively large and the first gate rod 10018 of the first gate is opened, the fixing column 10015 can block the carrier 10023 on the first conveyor belt 10081, and prevent the carrier positioning block 10022 from colliding with the hollow cup motor rotor on the carrier 10023 that opens the first gate rod 10018 when moving vertically, thereby damaging the product.

The tunnel 1008 can play a protective role, preventing other objects from entering the carrier positioning block 10022 and the moving path of the carrier 10023 in case of emergencies, thereby causing collision with other objects during movement.

[0358] The mounting seat of the present invention includes a bracket 11 and a second mounting plate 1004. Two parallel slideways 1001 are arranged on the bracket 11. The lead screw mechanism is in the middle of the two parallel slideways 1001 and is parallel to the two parallel slideways 1001. The upper end of the lead screw 10010 of the lead screw mechanism is fixedly mounted on the mounting seat through a bearing 10026, and the lower end is connected to a driven gear 1006. The motor 1003 is fixedly mounted on the bracket 11 through the second mounting plate 1004. Photoelectric sensors 10016 are arranged at both the upper and lower ends of the bracket 11 to detect the upper and lower limit positions of the sensor sheet 10017. A tunnel 1008 is arranged at the upper end of the base 10014, and a photoelectric sensor 10019 is installed at the bottom of the tunnel 1008. The exit 10021 of the tunnel 1008 is arranged on the table surface of the workbench. A slot is opened at the bottom entrance of the tunnel 1008, and the slot is used to facilitate the entry or output of the reflux carrier 10023.

[0359] The first vertical conveying mechanism and the second vertical conveying mechanism of the present invention work as follows: after the motor 1003 is energized, it drives the rotation of the driving gear 1005, and the rotation of the driving gear 1005 drives the rotation of the driven gear 1006. The rotation of the driven gear 1006 drives the rotation of the lead screw 10010. The rotation of the lead screw 10010 causes the transmission nut 10020 to move up and down. The up and down movement of the transmission nut 10020 drives the slider 12 fixedly mounted on the transmission nut 10020, so that the slider 12 moves up and down along the slideway 1001, and at the same time drives the lever 10024 to move up and down. The lever 10024 is fixedly connected to the carrier positioning block 10022. The up and down movement of the lever 10024 drives the carrier positioning block 10022 to move up and down.

[0360] The working process of the second vertical conveying mechanism is as follows: the carrier 10023 is conveyed to the carrier positioning block 10022 above the tunnel 1008 of the second vertical conveying mechanism through the second conveyor belt conveyor, and the first photoelectric sensing module senses the carrier 10023 on the carrier positioning block 10022. The second gate rod 10028 of the second gate machine blocks the carrier 10023 on the second conveyor belt 10082 behind from continuing to move. The motor 1003 of the second vertical conveying mechanism rotates, driving the transmission nut 10020 and the carrier positioning block 10022 to move downward to the lower limit position. The second photoelectric sensing module senses the carrier 10023 on the carrier positioning block 10022, and then the push rod 10030 of the carrier 10023 pushing mechanism pushes the carrier 10023 out of the gap in the tunnel 1008 to the first transmission belt for transmission. The second sensing module 10031 cannot sense that there is a carrier 10023 on the carrier positioning block 10022 in the tunnel 1008, and the motor 1003 drives the transmission nut 10020 to carry the carrier positioning block 10022 up to the top of the tunnel 1008, and the carrier 10023 then moves to the carrier positioning block 10022, and the previous process is repeated.

[0361] The working process of the first vertical conveying mechanism is as follows: when the carrier 10023 enters the tunnel 1008 from the gap at the bottom of the tunnel 1008 of the first vertical conveying mechanism, the carrier 10023 is above the carrier positioning block 10022, and is supported by the carrier positioning block 10022. The transmission nut 10020 drives the lever 10024 to move upward, and the lever 10024 pushes the carrier positioning block 10022, so that the carrier positioning block 10022 transports the carrier. 10023 moves upward in the tunnel 1008. At the same time, the first cylinder 1007 of the first gate machine pushes the first gate rod 10018 to prevent the vehicle 10023 behind from entering the vehicle positioning block 10022 in the tunnel 1008. After the vehicle positioning block 10022 moves upward, the fixed column 10015 moves upward under the elastic force of the compression spring. The fixed column 10015 is also used to prevent the entry of the vehicle 10023 behind, thereby playing a double insurance role. The vehicle positioning block 10022 transports the vehicle 10023 to the exit 10021 at the upper end of the tunnel 1008, the vehicle 10023 is taken away, the transmission nut 10020 drives the vehicle positioning block 10022 to move downward, depresses the fixed column 10015, and at the same time the push rod 10030 is recovered, the sensor 10019 cannot sense the presence of the vehicle 10023 in the tunnel 1008, and a new vehicle 10023 will enter the tunnel 1008, and the previous process is repeated.

[0362] Reference Fig.51 In the dispensing mechanism of the present invention, the vibration plate is fixedly mounted on the table, and the rotor frame and the rotor shaft fixed thereon are arranged in a line through the vibration plate 11 and flow into the rotor frame discharge track 12. The rotor frame discharge track 12 is provided with a groove that runs through from top to bottom. The rotor shaft on the rotor frame can fall from the groove under its own weight, so that the rotor shaft becomes vertical, and the rotor frame will not fall from the groove, and is still supported by the rotor frame discharge track 12. The rotor shaft manipulator moves forward to clamp the rotor frame and the rotor shaft from the rotor frame discharge track 12, and retreats, moves right to the dispensing station, moves forward, puts the rotor frame into the tooling 608, releases the manipulator, retreats, and moves left to return to the starting position. The hose mounting frame is used to install the dispensing hose, and the glue is evenly applied to the rotor frame through the dispensing needle tube. A rotating module is installed under the tooling, which can drive the tooling and the rotor frame to rotate. The present invention is provided with tooling in multiple places for placing the rotor frame, and some of the tooling can be driven to rotate by a motor.

[0363] After the first dispensing mechanism is completed, it enters the rotary pressing device of the assembly mechanism, where the rotary pressing device has three stations: commutator assembly, commutator pressing, and commutator height detection. After the commutator is pre-assembled, the robot takes the commutator and rotor frame and sends them to the tooling of the pressing device. The installed commutator is further pressed into the rotor frame through the pressing device so that the commutator and rotor frame can be tightly combined. The robot takes the pressed rotor frame and commutator and puts them into the tooling of the detection station. The height of the commutator to the shaft end is detected by the height detection device to determine whether the commutator is pressed in place.

[0364] After the inspection, the rotor frame and commutator enter the next station to install the sleeve. The robot takes the qualified products after the inspection and puts them into the tooling of the sleeve installation station. The sleeve of the vibration plate of the automatic sleeve discharging device flows out from the vibration plate of the sleeve outlet and is placed into the top of the rotor shaft by the robot. Further, the robot takes the rotor frame and the steering gear with the sleeve installed, and puts them into the tooling of the spot welding station. A tin spot is welded to each commutator segment of the commutator through the first welding mechanism. After that, the rotor frame and the commutator enter the press-fitting device of the next station to assemble the rotor frame and the wire cup. This process includes three stations: the second glue dispensing mechanism performs glue dispensing, the rotor frame is placed in the wire cup, and the rotor frame is pressed into the wire cup station. The robot takes the rotor frame after soldering and puts it into the tooling of the station where the second glue dispensing mechanism is located. The second glue dispensing mechanism evenly applies a layer of glue on the rotor frame. The mechanical material picker takes the rotor frame.

[0365] Among them, the seven manipulators of the transfer mechanism are all installed on the mounting plate through cylinders, and two cylinders control the forward and backward movement of the manipulators respectively, and the cylinder controls the left and right movement of the manipulators. And these seven manipulators move at the same time, taking out the rotor frame from the previous station and putting it into the next station.

[0366] The carrier carrying the wire cup is transported backwards through the conveyor belt. The shift fork is used to push the carrier from one conveyor belt to another vertical conveyor belt. After the carrier reaches the bottom of the conveyor belt, the material picking device rotates the rotor frame and places it into the inner wall of the wire cup and inserts it into the center hole of the carrier. The shift fork pushes the carrier with the rotor frame into the conveyor belt. The carrier carrying the rotor frame and wire cup that need to be pressed flows into the pressing station.

[0367] The material-dispensing hand moves forward, grabs the carrier on the conveyor belt through the arc part at the end of the material-dispensing hand, moves, and pushes the pressed carrier into the entrance of the baking mechanism through the other part, and at the same time pushes the carrier that has not been pressed to the bottom of the pressing station to press the rotor frame and the wire cup, and the material-dispensing hand moves back and moves left to return to its original position. The robot arm of the pressing station clamps the carrier at the same time, and the cylinder controls the die to move downward, pressing the rotor frame into the wire cup, so that the rotor frame and the wire cup can fit more closely to form a semi-finished rotor.

[0368] The semi-finished rotor flows into the wire coiling mechanism after being baked successively. The material handling handle dials the carrier flowing out of the baking mechanism into the wire coiling mechanism. The wire coiling mechanism is provided with a rotating module and a carrier positioning device. The carrier positioning device drives the carrier to rotate through the rotating module. The cylinder pushes the pressure head to press down the wire end of the wire cup, so that the wire end of the wire cup fits tightly with the tin point of the commutator, so that the next module can be carried out better.

[0369] Furthermore, after winding, the semi-finished rotor enters the welding mechanism, which includes an automatic welding device and a detection device. The material handling handle pushes the carrier directly under the automatic welding device, and the automatic welding device welds the wire cup thread end and the commutator together.

[0370] Furthermore, the semi-finished rotor after welding is conveyed to the welding spot detection station, the manipulator fixes the carrier, the welding spot identification device detects the welding spot, eliminates the situation of false welding and leaking welding, and at the same time, the material hand pulls the carrier that has been detected correctly into the next detection station, the manipulator clamps the carrier pulled by the material hand, the sleeve material taking device extends into the sleeve, and the sleeve is clamped and taken away by the manipulator, the commutator detection head clamps the commutator segment of the commutator, and the display screen displays the values ​​of the inter-turn resistance of the wire cup to determine that the wire cup and the commutator are in good contact and there are no problems such as short circuit. After the inspection, the qualified products are conveyed to the second glue dispensing mechanism, the material hand pulls the carrier to the bottom of the second glue dispensing mechanism, and the second glue dispensing mechanism of the automatic glue dispensing device dispenses the first flat glue to the semi-finished rotor, and at the same time, the semi-finished rotor after glue dispensing is pushed into the entrance of the baking mechanism by the material hand. The semi-finished rotor coming out of the baking mechanism repeats the process of applying flat glue and baking, and the finished rotor comes out of the baking mechanism.

[0371] During the entire production process, the first dispensing mechanism needs to dispense glue twice, the second dispensing mechanism needs to dispense flat glue twice, and the process needs to be baked three times to ensure that the rotor frame and the wire cup can fit tightly together, and that the wire cup and the rotor frame will not loosen during the high-speed rotation of the rotor.

[0372] After the finished rotor flows out, it enters the finished product swing plate mechanism and the carrier reflux mechanism. At the finished product swing plate mechanism, the robot takes the finished rotor and puts it into the finished product plate. The robot takes the sleeve and puts it into the remaining containers separately.

[0373] The carrier reflux mechanism drives the carrier and the carrier positioning device to rise to the table along the vertical track to complete the reflux.

[0374] All the above-mentioned mechanisms are equipped with control panels, three-color alarm lights and buzzers. When any workstation fails, the buzzer of the machine will sound and the three-color alarm light will flash in three colors, indicating an alarm. At the same time, the entire production line will stop urgently and can only operate after maintenance and troubleshooting to ensure safety.

[0375] It should be noted that since this production line includes many parts, such as motors, cylinders, carriers, rotating bases, tooling, mounting plates, mounting seats and other parts, and since multiple mechanisms on this production line contain parts with the same name and are set up in multiple places, if the present invention has different numbers for the same part, it can be considered that different mechanisms contain the part, but the part numbers are different, and the parts in different mechanisms are distinguished by the different numbers of the same part. For example, there are rotating bases in welding mechanisms and coiling mechanisms, but the numbers of the parts on the rotating bases in different mechanisms will be different, so that the numbers of the parts with the same name of the rotating bases in different mechanisms or workstations will be different, and the parts with the same name in different mechanisms can be distinguished by different numbers. Of course, the conventional method of adding "first", "second", "third"... etc. before the name can also be used to distinguish.

[0376] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
