[0041] See also Figure 1 as well as Figure 2As shown, the present application proposes a meson assembly device, including a frame 1, a turntable assembly 2 rotatably arranged on the frame 1, and a rotor loading device 3, a first meson pressing device 4, a copper ring pressing device 5, a second meson pressing device 6, a rotor turning device 15, a third meson pressing device 7, a fourth meson pressing device 8, a rotor unloading device 10 and a loading and unloading conveying device 11 which are sequentially arranged on the frame 1 around the turntable assembly 2.

[0042] The turntable assembly 2 includes a turntable body 21 and a plurality of dies 22 for magnetically attracting the rotor, which are movably arranged on the circumferential side of the turntable body 21; the rotation of the turntable assembly 2 can drive the dies 22 to pass through the rotor loading device 3, the first meson pressing device 4, the copper ring pressing device 5, the second meson pressing device 6, the third meson pressing device 7, the fourth meson pressing device 8 and the rotor unloading device 10 in sequence; the loading and unloading conveying device 11 is connected to the rotor loading device 3 and the rotor unloading device 10, and is used for conveying the rotor during loading and unloading.

[0043] The technical solution of the present application, such as the rotor feeding device 3, the copper ring pressing device 5, the first meson pressing device 4, etc., which are arranged around the turntable assembly 2, are a corresponding processing station, wherein the first meson pressing device 4 corresponds to the installation of the first meson on the rotor, the second meson pressing device 6 corresponds to the installation of the second meson on the rotor, the third meson pressing device 7 corresponds to the installation of the third meson on the rotor, and the fourth meson pressing device 8 corresponds to the installation of the fourth meson on the rotor. The types of the first meson, the second meson, the third meson and the fourth meson can be partially the same or completely different, and the user can install different mesons on the rotor based on actual needs. Among them, the meson types include adjustment mesons, insulating mesons and oil-stopping mesons. If more than four mesons need to be installed, the fifth and sixth meson pressing devices can also be arranged around the turntable assembly 2 on the frame 1.

[0044] Based on the above structural setting, after the rotor is loaded onto the mold 22, it can follow the turntable body 21 to move to the workstation corresponding to each device, and each device cooperates with the mold 22 to realize the assembly of copper rings and various mesons; the automation integration is high, no manual transfer is required, the production efficiency is high and it is not easy to make mistakes.

[0045] See also Figure 3 as well as Figure 4As shown, in some embodiments, the loading and unloading conveying device 11 includes a loading conveying mechanism 12, a unloading conveying mechanism 13 and a jig line changing mechanism 14; the loading conveying mechanism 12 includes a loading conveying belt 121 arranged below the rotor loading device 3, and the head end of the loading conveying belt 121 is connected to the previous processing equipment for feeding and conveying the rotor; the unloading conveying mechanism 13 includes a unloading conveying belt 131 parallel to the loading conveying belt 121 and arranged below the rotor unloading device 10, and the unloading conveying belt 131 is used for unloading and conveying the rotor; the jig line changing mechanism 14 is arranged between the tail end of the loading conveying belt 121 and the head end of the unloading conveying belt 131; wherein, the loading conveying belt 121 and the unloading conveying belt 131 carry the rotor for conveying by placing a jig 60 thereon, and the jig line changing mechanism 14 is used to transfer the placed jig 60 on the loading conveying belt 121 to the unloading conveying belt 131 for transportation.

[0046] In this embodiment, based on the position correspondence between the loading conveyor belt 121, the unloading conveyor belt 131 and the fixture line changing mechanism 14, as well as the position correspondence between the loading conveyor belt 121 and the rotor loading device 3 and the position correspondence between the unloading conveyor belt 131 and the rotor unloading device 10, it can be achieved that:

[0047] When the loading conveyor belt 121 transports the placement jig 60 with the rotor placed on it to the bottom of the rotor loading device 3, the rotor on the placement jig 60 can be grabbed by the rotor loading device 3 and transferred to the backing mold 22 to complete the loading of the rotor, so as to follow the movement of the backing mold 22 to realize the installation of the copper ring and the meson; and after all the rotors on the placement jig 60 are grabbed, the empty placement jig 60 can continue to be transported along the loading conveyor belt 121 to the corresponding position of the jig line changing mechanism 14, and the jig line changing mechanism 14 transfers the empty placement jig 60 to the unloading conveyor belt 131 for further transportation, and when the empty placement jig 60 is transported to the bottom of the corresponding rotor unloading device 10, the rotor unloading device 10 transfers the rotor with the copper ring and the meson installed from the backing mold 22 to the empty placement jig 60 for unloading.

[0048] In this way, the loading and unloading conveying device 11 designed in this embodiment can achieve seamless connection between the placement jig 60 for loading and unloading the rotor, reduce the manual transportation of the placement jig 60, improve efficiency and save costs.

[0049] See also Figure 3 As shown, in some embodiments, a limiting guide plate 123 is provided on both sides of the loading conveyor belt 121 and the unloading conveyor belt 131; the limiting guide plate 123 can guide and limit the movement of the placement fixture 60 and the conveyor belt to achieve precise transportation.

[0050] For further information, see Figure 4As shown, the placement jig 60 is provided with a plurality of accommodating holes 61 along the conveying direction of the conveyor belt, and one placement jig 60 simultaneously transports a plurality of rotors; wherein, slots 62 are provided on both sides of the placement jig 60 corresponding to the accommodating holes 61, and a first clamping block 122 is movably provided on one side of the loading conveyor belt 121 corresponding to the rotor loading device 3, and a second clamping block 132 is movably provided on one side of the unloading conveyor belt 131 corresponding to the rotor unloading device 10, and both the first clamping block 122 and the second clamping block 132 can be inserted into the clamping slot 62 on the placement jig 60.

[0051] In this embodiment, the function of the first clamping block 122 is to cooperate with the clamping slot 62 on the placement jig 60 so that the placement jig 60 is limited to the bottom of the rotor loading device 3, which facilitates the rotor loading device 3 to grab the rotor from the placement jig 60; the function of the second clamping block 132 is to cooperate with the clamping slot 62 on the placement jig 60 so that the placement jig 60 is limited to the bottom of the rotor unloading device 10, which facilitates the rotor unloading device 10 to transfer the rotor to the placement jig 60.

[0052] It can be understood that the slots 62 are opened corresponding to the receiving holes 61 , and during the rotor feeding process, when the first block 122 is inserted into the corresponding slot 62 , the rotor in the receiving hole 61 corresponding to the slot 62 is positioned below the rotor feeding device 3 . Exemplarily, the placement jig 60 is provided with a first receiving hole, a second receiving hole, a third receiving hole and a fourth receiving hole, and the first card slot and the fourth card slot are respectively provided on the side of the placement jig 60 corresponding to the first receiving hole-the fourth receiving hole. When the first card block 122 is driven to be inserted into the first card slot during the rotor loading process, the first receiving hole corresponds to the rotor loading device 3 arranged above, and the rotor loading device 3 can grab the rotor of the first receiving hole for transfer loading; after completing the transfer of the rotor in the first receiving hole, the first card block 122 can withdraw from the first card slot, and the placement jig 60 continues to move, and further the first card block 122 can be inserted into the second card slot so that the second receiving hole corresponds to the rotor loading device 3 arranged above, and the rotor loading device 3 can grab the rotor of the second receiving hole for transfer loading. Therefore, based on the cooperation between the first card block 122 and the card slot 62, the receiving hole 61 on the placement jig 60 can be sequentially made to correspond to the rotor loading device 3 above, and the rotor transfer loading is completed based on the rotor loading device 3.

[0053] Similarly, during the rotor unloading process, based on the cooperation between the second clamping block 132 and each clamping slot 62 , the receiving holes 61 on the placement fixture 60 can correspond to the rotor unloading device 10 above in sequence, and the rotor unloading is completed based on the rotor unloading device 10 .

[0054] In some embodiments, the corresponding rotor loading device 3 is provided with a first sensor detector (not shown in the drawings) on the side of the loading conveyor belt 121, and the first sensor detector is used to detect whether the rotor is transported into place and whether the rotor is transferred; the corresponding rotor unloading device 10 is provided with a second sensor detector (not shown in the drawings) on the side of the unloading conveyor belt 131, and the second sensor detector is used to detect whether the unloading and placement of the rotor in the accommodating hole 61 is completed.

[0055] The first sensor detector and the second sensor detector may both be infrared grating sensors. The rotor loading device 3 and the rotor unloading device 10 are a combination of a conventional manipulator and a mobile module, which will not be described in detail here.

[0056] See also Figure 4 As shown, in some embodiments, the jig line changing mechanism 14 includes a docking plate 141, a push plate 142 and a position sensor 143; one end of the docking plate 141 is docked with the tail end of the loading conveyor belt 121, and the other end is docked with the head end of the unloading conveyor belt 131; the push plate 142 is movably arranged on the side of the loading conveyor belt 121 away from the unloading conveyor belt 131, and is used to push the placement jig 60 from the tail end of the loading conveyor belt 121 to the head end of the unloading conveyor belt 131; the detection path of the position sensor 143 covers the tail end of the loading conveyor belt 121 and the head end of the unloading conveyor belt 131, and is used to detect whether the placement jig 60 is delivered to the right place.

[0057] In this embodiment, the docking plate 141 is arranged between the feeding conveyor belt 121 and the unloading conveyor belt 131. When the push plate 142 pushes the placement jig 60, the placement jig 60 moves on the docking plate 141 to be transferred to the unloading conveyor belt 131. Among them, the push plate 142 is an "L"-shaped plate, and its initial position is docked at the tail end of the feeding conveyor belt 121. When the placement jig 60 is transported along the feeding conveyor belt 121, the placement jig 60 can be limited in the space formed by the angle of the "L"-shaped plate. In this way, on the one hand, the placement jig 60 is prevented from being separated from the feeding conveyor belt 121, and on the other hand, the stability of the placement jig 60 when the push plate 142 pushes the placement jig 60 can be improved.

[0058] See also Figure 2 As shown, in some embodiments, the mold 22 includes a fixed seat 221, a magnetic portion 222 and an elastic return member 223; the fixed seat 221 is installed on the turntable body 21; the magnetic portion 222 is slidably connected to the fixed seat 221 in the vertical direction, and an arc-shaped fitting groove that fits the outer periphery of the rotor is formed on the magnetic portion 222; one end of the elastic return member 223 is connected to the fixed seat 221, and the other end is connected to the magnetic portion 222.

[0059] In this embodiment, the magnetic attraction part 222 is slidably arranged in the vertical direction, and its purpose is to cooperate with the device in the subsequent workstation to realize the installation of the copper ring or each meson, that is, when installing the copper ring or each meson, it is necessary to press down the rotor to move the magnetic attraction part 222 downward. Among them, the arc-shaped fitting groove formed by the magnetic attraction part 222 can facilitate the installation of the rotor and the subsequent removal and placement of the rotor. When the magnetic attraction part 222 moves downward, it can drive the elastic return part 223 to undergo elastic deformation, and after the installation of the copper ring or each meson is completed, the elastic return part 223 will drive the magnetic attraction part 222 to reset under the action of its own elastic force.

[0060] The elastic restoring member 223 may be a telescopic spring. Two groups of the telescopic springs are provided on both sides of the magnetic attraction portion 222 to form a stable elastic restoring force.

[0061] See also Figure 5-Figure 8 As shown, in some embodiments, the copper ring pressing device 5 includes a copper ring pre-pressing assembly and a copper ring precision pressing assembly; the copper ring pre-pressing assembly includes a vibrating feeding mechanism 52, a pre-pressing fixing seat 51 and a pre-pressing ram 53, the vibrating feeding mechanism 52 is used to sequentially convey the copper rings to the pre-pressing fixing seat 51, the pre-pressing ram 53 is arranged above the pre-pressing fixing seat 51, the pre-pressing ram 53 is used to press down and cooperate with the pre-pressing fixing seat 51 to pre-load the copper ring onto the rotor; the copper ring precision pressing assembly includes a precision pressing lower die column 54 and a precision pressing ram 55, the precision pressing ram 55 is arranged above the precision pressing lower die column 54, the precision pressing ram 55 is used to press down and cooperate with the precision pressing lower die column 54 to precision press the copper ring into place.

[0062] In this embodiment, the copper ring pressing includes two steps: pre-assembly and fine assembly.

[0063] The copper ring preloading assembly is used to preliminarily position the copper ring on the rotor, specifically, on the rotating shaft of the rotor. During the preloading process of the copper ring, a vibrating feeding mechanism 52 is used for feeding. The vibrating feeding mechanism 52 includes a vibrating plate mechanism and a direct vibration mechanism connected to the output end of the vibrating plate mechanism. The vibrating plate mechanism is used to screen and convey the copper ring to the direct vibration mechanism, and the direct vibration mechanism can vibrate and convey the copper ring to the preloading fixed seat 51. Among them, a preloading station 511 is formed on the preloading fixed seat 51, and the direct vibration mechanism conveys the copper ring to the preloading station 511. Further, the preloading ram 53 is arranged corresponding to the preloading station 511. When the rotor fixed on the backing mold 22 is transferred to the top of the preloading station 511, the preloading ram 53 moves downward to drive the rotor to move downward until the rotating shaft on the rotor passes through the copper ring. After the preloading ram 53 is reset, the elastic recovery member 223 in the backing mold 22 drives the rotor to reset and can simultaneously drive the copper ring in the preloading station 511 to move.

[0064] It is understandable that the diameter of the rotating shaft on the rotor should be slightly larger than the inner diameter of the copper ring, so that after the rotating shaft on the rotor is inserted into the copper ring, it can form a tight fit with the copper ring, and will not fall off the rotor after the rotor is reset. In the pre-pressing station 511 formed by the pre-pressing fixing seat 51, a first avoidance hole (not shown in the figure) is formed corresponding to the rotating shaft of the rotor, so that the rotating shaft can be inserted downward during the rotor pressing process, so that the rotating shaft moves downward through the copper ring.

[0065] A copper ring detection component 512 is further provided corresponding to the pre-pressing station 511 . The copper ring detection component 512 is an infrared grating sensor for detecting whether the copper ring transported by the direct vibration mechanism is in place, that is, whether there is a copper ring in the pre-pressing station 511 .

[0066] The copper ring coining assembly is used to coin-press the pre-pressed copper ring into place. Specifically, the coining head 55 cooperates with the coining lower die column 54 to coin-press the copper ring into place. The copper ring coining pressing process is similar to the copper ring pre-pressing pressing process. The copper ring coining pressing process includes: the rotor with the copper ring pre-pressed is transferred to between the coining lower die column 54 and the coining head 55 along with the backing die 22, and the coining head 55 moves downward to drive the rotor to move downward until the copper ring sleeved on the shaft is pressed into place.

[0067] See also Figure 7 as well as Figure 8 As shown, in some embodiments, the precision pressing lower mold column 54 includes a column and a wire package testing mechanism; wherein, the column is used to cooperate with the precision pressing head 55 to precision press the copper ring into place; the wire package testing mechanism includes a wire package testing plate 542, an elastic reset member 543 and a displacement sensor 544, the wire package testing plate 542 is movably arranged on the column and can be moved in the vertical direction, the elastic reset member 543 is arranged between the wire package testing plate 542 and the column, and the displacement sensor 544 is used to detect whether the wire package testing plate 542 moves.

[0068] In this embodiment, by providing a wire package testing mechanism in the coining lower die column 54, it is possible to detect wire package defects while achieving coining of the copper ring in place.

[0069] Specifically, the column in this embodiment includes a first column 540 and a second column 541, wherein the diameter of the second column 541 is smaller than the diameter of the first column 540, and the second column 541 is arranged at the top center of the first column 540; during the copper ring coining process, the second column 541 cooperates with the coining head 55 to coin the copper ring into place. A second avoidance hole 5411 is arranged at the top center of the second column 541 for the shaft in the rotor to be inserted downward. The second avoidance hole 5411 can extend into the first column 540.

[0070] The wire package test plate 542 is sleeved on the second column 541, the elastic reset member 543 is arranged between the wire package test plate 542 and the first column 540, and the displacement sensor 544 is fixed to the side of the first column 540. After the copper ring is precisely pressed in place, if the rotor wire package is defective, the wire package in the rotor will further press the wire package test plate 542 below, and the wire package test plate 542 overcomes the elastic force of the elastic reset member 543 to move and is detected by the displacement sensor 544, thereby detecting the defective wire package. After the precision pressing head 55 is reset, the wire package test plate 542 is also reset under the drive of the elastic reset member 543.

[0071] In some embodiments, a blind hole (not shown in the drawings) is provided on the second column 541, and a guide column 545 is arranged below the wire package test plate 542, the guide column 545 is inserted into the blind hole, and a waist-shaped hole 5401 passing through the blind hole and the outside is provided on the side wall of the second column 541, a limiting column 546 is inserted into the waist-shaped hole 5401 and connected to the guide column 545; wherein the elastic reset member 543 is a telescopic spring, which is sleeved on the guide column 545 between the wire package test plate 542 and the first column 540.

[0072] In this embodiment, by providing the guide column 545, the telescopic spring can be easily installed. After further providing the limit column 546, the upward movement of the wire package test plate 542 can be limited to prevent the wire package test plate 542 from being separated from the second column 541 under the drive of the elastic reset member 543, and the wire package test plate 542 can be prevented from rotating, thereby playing a role in structural stability.

[0073] There are two groups of blind holes and guide pillars 545 , which are arranged on two sides of the second pillar 541 opposite to each other.

[0074] The present application proposes the structure of a meson pressing device. Since the structural shapes of the first meson, the second meson, the third meson and the fourth meson are basically the same, the first meson pressing device 4, the second meson pressing device 6, the third meson pressing device 7 and the fourth meson pressing device 8 are all meson pressing devices of the same type. After knowing the structure of one of the meson pressing devices, the structural design of other meson pressing devices can be known.

The feed part 421 is arranged above the screening part, and the feed part 421 is a feed funnel, which can facilitate the user to put in the mesons, and after the user puts the mesons into the feed funnel, the mesons can enter the screening part under the action of their own gravity to screen out the materials.

[0077] See also Fig.10 As shown, in some embodiments, the screening part includes a cylinder 422 and a toggle mechanism, wherein a material trough 4221 is arranged below the cylinder 422, and a discharge hole 4222 is opened at the bottom of the material trough 4221; the toggle mechanism includes a toggle shaft 423 arranged in the middle of the cylinder 422, and a plurality of toggle plates 424 are arranged on the circumference of the toggle shaft 423, and the plurality of toggle plates 424 are arranged close to the material trough 4221 below.

[0078] In this embodiment, the process of discharging the mesons through the screening part is: the rotating shaft 423 is rotated, thereby driving multiple toggle plates 424 to rotate, and the toggle plates 424 drive multiple mesons to move along the whole material trough 4221. When a meson moves to the discharge hole 4222, the meson can fall onto the pushing mechanism through the discharge hole 4222.

[0079] See also Fig. 9 As shown, in some embodiments, the pushing mechanism includes a pushing plate 431 and a pushing driving member 432, wherein the pushing plate 431 is slidably disposed on the pressing base 41, and a bearing hole 4311 is provided on the pushing plate 431. Driven by the pushing driving member 432, the pushing plate 431 can be driven to move so that the bearing hole 4311 on the pushing plate 431 corresponds to the discharge hole 4222 in the screening part, or the bearing hole 4311 on the pushing plate 431 is moved to the pressing station.

[0080] Therefore, the meson screened by the feed screening assembly 42 falls onto the bearing hole 4311 on the push plate 431, and driven by the push drive 432, the meson is transferred to the pressing station, and then with the cooperation of the meson press head 44, the meson is installed on the rotor. Similarly, the meson is installed on the rotating shaft in the rotor.

[0081] In some embodiments, the positioning head 441 and the upper mold column 442, and the upper mold column 442 and the upper mold mounting member 443 are locked by machine screws. By setting the positioning head 441 and the upper mold column 442, and the upper mold column 442 and the upper mold mounting member 443 as detachable connections, different positioning heads 441 can be replaced to adapt to different types of rotors or replace damaged components of the meson press head 44, thereby improving the replaceability of the meson press head 44 and reducing the replacement cost. Among them, a screw connection interface can also be provided between the positioning head 441 and the upper mold column 442, and between the upper mold column 442 and the upper mold mounting member 443, so as to be locked by the screw connection interface.

[0082] The positioning head 441 is provided with a plug hole 4411 for inserting the rotating shaft in the rotor, so as to form a stable force when pressing down. The port of the plug hole 4411 is a trumpet-shaped entrance, which can facilitate the insertion of the rotating shaft.

[0083] See also Fig. 9 As shown, in some embodiments, the meson press head 44 is connected with a guide member, and the guide member is used to guide and limit when the driving member drives the meson press head 44 to move. It can be understood that the meson pressing device is established based on the meson mounting seat 48, and the meson mounting seat 48 is provided with a support plate 47, and the meson press head 44 and the driving member are connected to the support plate 47. The guide member can be a guide rod 46 fixedly connected to the meson press head 44, and the guide rod 46 is arranged through the support plate 47 to perform guiding and limiting.

[0084] In some embodiments, the rotor flipping device 15 includes a reversing drive mechanism and a rotating grabbing member; the rotating grabbing member is connected to the reversing drive mechanism, and the rotating grabbing member is used to grab the rotor on the mold 22 and perform rotational reversal; wherein, the rotating grabbing member moves away from or close to the mold 22 under the drive of the reversing drive mechanism.

[0085] It can be understood that the rotating shaft in the rotor passes through the iron core, and the mesons need to be installed on the rotating shafts on both sides of the iron core. Therefore, after the mesons on one side are installed, the direction of the rotor needs to be adjusted to install the mesons on the other side. The rotor turning device 15 in this embodiment is used for the commutation of the rotor.

[0086] In some embodiments, the meson assembly equipment also includes a meson detection device 9 arranged between the fourth meson pressing device 8 and the rotor unloading device 10. The meson detection device 9 includes a detection pressure head and a detection base arranged below the detection pressure head. A detection plate and a detection sensor corresponding to the detection plate are movably arranged in the detection base. The detection sensor is used to detect whether the position of the detection plate changes after the meson is pressed down by the detection pressure head, and judge whether the meson is installed in place according to the position change.
