DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Figure 1 A schematic structural diagram of a compressor rotor loading device in an embodiment of the present invention is shown; the rotor loading device 100 comprises: a loading portion 11 and a detection portion 12, the loading portion 11 is located on the left side of the detection portion 12, the loading portion 11 is used to transport the rotor from the feed end to the detection portion 12, and the detection portion 12 is used to detect the rotor model and appearance.

[0039] Figure 2 The schematic diagram of the structure of the feeding part in the embodiment of the present invention is shown, and the feeding part 11 comprises: a feeding track group 111, a lifting V-shaped groove 113 and a feeding mechanism, wherein the lifting V-shaped groove 113 is located at the discharge end of the feeding track group 111, and the feeding mechanism is located above the lifting V-shaped groove 113. The feeding track group 111 is used to transport the rotor from the feeding end to the lifting V-shaped groove 113, and the lifting V-shaped groove 113 is used to move the rotor along the Z-axis direction to the bottom of the feeding push plate 114, and the feeding mechanism is used to move the rotors in the lifting V-shaped groove 113 to the detection part 12 one by one.

[0040] Furthermore, the feeding part 11 is also provided with a base 110, and the base 110 is provided with a first fixing frame 1101 supporting the lifting V-shaped groove 113 and a second fixing frame 1102 supporting the feeding push plate 114. The first fixing frame 1101 is located on a side of the second fixing frame 1102 close to the feeding track group, ensuring that the lifting V-shaped groove 113 is located at the discharge end of the feeding track group.

[0041] Figure 3 The schematic diagram of the structure of the feeding track group in the embodiment of the present invention is shown, the feeding track group 11 includes a support frame and a plurality of feeding tracks located on the support frame, the feeding track group 111 is used to slide the rotors from the feeding end into the lifting V-shaped groove 113, and the rotors on each sub-feeding track are neatly arranged along the X-axis. In this embodiment, the plurality of feeding tracks are five feeding tracks. The number of rotors sliding from the feeding track group to the lifting V-shaped groove 113 each time is five, that is, each sub-feeding track slides off a rotor, which can meet the simultaneous feeding and conveying of multiple rotors, so that the entire feeding progress can meet the beat of the entire production line. The loading rail group 111 includes a support frame and a plurality of loading rails located on the support frame, the support frame can fix the plurality of loading rails and make the plurality of loading rails have a certain operating height, each loading rail in the loading rail group 111 includes: a left rail plate 1111 and a right rail plate 1112, the left rail plate 1111 and the right rail plate 1112 are placed at a preset interval; the interval between the left rail plate 1111 and the right rail plate 1112 is less than the thickness of a rotor, so that the sub-loading rail can support the rotor above the sub-loading rail. The top of the left track plate 1111 extends obliquely upward to the left side to form a left inclined surface, and the top of the right track plate 1112 extends obliquely upward to the right side to form a right inclined surface. A sliding groove 1113 is formed between the left inclined surface and the right inclined surface. The sliding groove 1113 facilitates the rotor to slide smoothly directly from the feed end of the loading track to the discharge end of the sliding groove 1113, and provides better support and guidance for the rotor during the sliding process, ensuring that the rotor slides more smoothly and accurately in the sliding groove 1113 to the specified position.

[0042] Furthermore, a height adjustment mechanism 112 is provided at the bottom of the feed end of the loading track group 111, and the height adjustment mechanism 112 is fixed on the support frame. The height adjustment mechanism 112 is used to adjust the height of the feed end of the loading track group 111 so that there is a certain sliding height between the feed end and the discharge end. The sliding height allows the rotor to slide freely from the feed end to the discharge end according to its own gravity. The height adjustment mechanism 112 is provided with an adjusting screw and an adjusting valve, and the adjusting valve is inserted on the adjusting screw. The height adjustment mechanism 112 can realize the height adjustment of the feed end. When the height adjustment mechanism 112 needs to be raised, the regulating valve rotates clockwise to move the regulating screw rod upward, thereby adjusting the height of the feed end of the plurality of feeding tracks, so that the height difference between the feed end of the plurality of feeding tracks and the discharge end of the plurality of feeding tracks becomes larger; when the height adjustment mechanism 112 needs to be lowered, the regulating valve rotates counterclockwise to move the regulating screw rod downward, thereby adjusting the height of the feed end of the plurality of feeding tracks, so that the height difference between the feed end of the plurality of feeding tracks and the discharge end of the plurality of feeding tracks becomes smaller. The height adjustment mechanism 112 forms a height difference between the feed end of the plurality of feeding tracks and the discharge end of the plurality of feeding tracks, which is conducive to the rotor being able to use its own gravity to slide along the sliding groove 1113 from the input end of the sliding groove 1113 to the output end of the sliding groove 1113 spontaneously.

[0043] Furthermore, a fixed plate 1114 is provided above the feeding track group 111, and the fixed plate 1114 spans the five feeding tracks. A plurality of induction switches are provided on the fixed plate 1114, and the plurality of induction switches are provided at the bottom of the fixed plate 1114. One of the plurality of induction switches corresponds to one of the plurality of feeding tracks, and the output end of the induction switch is aligned with the discharge end of the feeding track. The induction switch is used to detect whether there is a rotor on the corresponding feeding track. When the induction switch detects that there is no rotor on the feeding track, an alarm will be issued to remind the staff that materials need to be provided to the feeding part 11, which is conducive to reducing breakpoints on the production line and improving the production efficiency of the production line.

[0044] Figure 4The schematic diagram of the structure of the lifting V-shaped groove in the embodiment of the present invention is shown, and the lifting V-shaped groove 113 is used to move the rotor entering the lifting V-shaped groove 113 to the feeding mechanism along the Z-axis direction. The lifting V-shaped groove 113 includes: a movable inclined plate 1131, a fixed inclined plate 1132 and a driving mechanism, the fixed inclined plate 1132 is located on the first fixed frame 1101, and the fixed inclined plate 1132 is fixedly arranged below the feeding push plate 114, the movable inclined plate 1131 is located on one side of the fixed inclined plate 1132, and the movable inclined plate 1131 is driven by the driving mechanism to move between the bottom of the feeding track group 111 and the top of the feeding track group 111 along the Z-axis direction, thereby pushing the rotor that slides from the feeding track group 111 to the lifting V-shaped groove 113 to move in the positive direction of the Z-axis.

[0045] Specifically, the driving mechanism includes: a first driving cylinder 1133, a driving rod driven by the first driving cylinder 1133, the input end of the driving rod is inserted into the output end of the first driving cylinder 1133, and the output end of the driving rod is fixedly connected to the bottom of the movable inclined plate 1131. When the first driving cylinder 1133 pushes the input end of the driving rod to move along the positive direction of the Z axis, the movable inclined plate 1131 is pushed to move along the positive direction of the Z axis, so that the movable inclined plate 1131 moves from the bottom of the feeding track group 111 along the positive direction of the Z axis to the position where the top of the movable inclined plate 1131 is flush with the top of the feeding track group 111. When the first driving cylinder 1133 pulls the driving input end to move along the negative direction of the Z axis, the movable inclined plate 1131 is then pulled to move along the negative direction of the Z axis, so that the movable inclined plate 1131 moves from the top of the feeding track along the negative direction of the Z axis to a position where the top of the movable inclined plate 1131 is flush with the bottom of the feeding track. Furthermore, a preset interval is formed between the movable inclined plate 1131 and the fixed inclined plate 1132, and the preset interval can reduce the wear of the movable inclined plate 1131 and the fixed inclined plate 1132 when they slide relative to each other, thereby extending the service life of the movable inclined plate 1131 and the fixed inclined plate 1132.

[0046] Specifically, when the top of the movable inclined plate 1131 is level with the bottom of the feeding track set 111, the five rotors slide from the feeding track set 111 to the top of the movable inclined plate 1131 along the sliding groove 1113, and the outer surface of the rotor abuts against the top of the movable inclined plate 1131 and the fixed inclined plate 1132 at the same time, and the lifting V-shaped groove 113 clamps the rotor at the angle between the movable inclined plate 1131 and the fixed inclined plate 1132. The output end of the first driving cylinder 1133 moves forward along the Z-axis direction, driving the movable inclined plate 1131 to move forward along the Z-axis direction until the top of the movable inclined plate 1131 is level with the top of the feeding track set 111. During this process, the rotor on the sliding groove 1113 has no contact with the rotor in the lifting V-shaped groove 113, and the rotor on the sliding groove 1113 abuts against the vertical surface of the movable inclined plate 1131, and the vertical surface of the movable inclined plate 1131 prevents other rotors from sliding from the sliding groove 1113 to the inclined surface of the movable inclined plate 1131. When the rotors on the movable inclined plate 1131 are transported to the next process, the output end of the first driving cylinder 1133 moves negatively along the Z-axis direction, driving the movable inclined plate 1131 to move negatively along the Z-axis direction until the top of the movable inclined plate 1131 is flush with the bottom of the feeding track group 111. When the top of the movable inclined plate 1131 is flush with the bottom of the feeding track, the other five rotors slide from the feeding track group 111 to the top of the movable inclined plate 1131 along the sliding groove 1113.

[0047] Figure 5 The schematic diagram of the structure of the feeding mechanism in the embodiment of the present invention is shown. Figure 6 The enlarged structural schematic diagram of point A in the present invention is shown, and the feeding mechanism is used to move the rotors in the lifting V-shaped groove 113 to the detection part 12 one by one, that is, when the feeding track group 11 slides a batch of five rotors into the lifting V-shaped groove 113 at the same time, the feeding mechanism pushes the five sliding rotors into the detection part 12 one by one, ensuring that the feeding mechanism can push one or more rotors each time it operates, which is beneficial to speed up the feeding and detection speed and improve the efficiency of the production line.

[0048] The loading mechanism is located on the second fixed frame 1102, and the loading mechanism includes a Z-axis moving mechanism 115, a Y-axis moving mechanism 116 and a loading push plate 114. The Z-axis moving mechanism 115 is used to drive the loading push plate 114 to move along the positive and negative directions of the Z-axis, and the Y-axis moving mechanism 116 is used to drive the loading push plate 114 and the Z-axis moving mechanism 115 to move along the positive and negative directions of the Y-axis. The loading push plate 114 is used to change the position of the rotor so that the rotor can move to the corresponding position each time it changes its position.

[0049] Furthermore, five partitions 1141 are provided at the bottom of the loading push plate 114, and a rotor accommodating area is formed between any two adjacent partitions. A total of four rotor accommodating areas are formed at the bottom of the loading push plate 114, and one rotor accommodating area corresponds to one loading track and is located at the discharge end of the corresponding loading track, and the rotor accommodating area accommodates one rotor at a time. The five partitions 1141 are distinguished according to the distance from the detection part, wherein the partition 1141 closest to the detection part is the first partition, and the partition farthest from the detection part is the fifth partition, and the five partitions are located on one side of the left track plate 1111 corresponding to the loading track. The first baffle is used to push the first rotor close to the detection part 12 on the lifting V-shaped groove 113 to the corresponding position of the detection part 12, the second baffle is used to push the second rotor close to the detection part to the original position of the rotor close to the detection part, the third baffle is used to push the third rotor close to the detection part to the original position of the rotor close to the detection part, the fourth baffle is used to push the fourth rotor close to the detection part to the original position of the rotor close to the detection part, and the fifth baffle is used to push the fifth rotor close to the detection part to the original position of the fourth rotor close to the detection part.

[0050] Furthermore, the Z-axis moving mechanism 115 includes: a Z-axis moving slide rail 1151, a second driving cylinder 1152 and a connecting plate 1153, wherein the connecting plate 1153 is fixedly connected to the loading push plate 114; the loading push plate 114 is fixedly connected to the bottom of the connecting plate 1153 by bolts, which is conducive to adjusting the use length of the loading push plate 114 according to different types of rotors. The top of the connecting plate 1153 is connected to the output end of the second driving cylinder 1152, and the side of the connecting plate 1153 is movably connected to the Z-axis moving slide rail 1151. The connecting plate 1153 is driven by the second driving cylinder 1152 to move between the bottom of the Z-axis moving slide rail 1151 and the top of the Z-axis moving slide rail 1151. When the output end of the second driving cylinder 1152 moves along the negative direction of the Z-axis, it pushes the connecting plate 1153 to move along the negative direction of the Z-axis, thereby driving the loading push plate 114 to move along the negative direction of the Z-axis, so that the partition 1141 approaches the lifting V-shaped groove 113; when the output end of the second driving cylinder 1152 moves along the positive direction of the Z-axis, it pushes the connecting plate 1153 to move along the positive direction of the Z-axis, thereby driving the loading push plate 114 to move along the positive direction of the Z-axis, so that the partition 1141 is away from the lifting V-shaped groove 113, thereby preventing the loading structure from pushing the rotor back to its original position when resetting, thereby improving the loading efficiency of the loading mechanism.

[0051] Furthermore, the Y-axis moving mechanism 116 includes: a Y-axis moving rail 1161, a third driving cylinder 1162 and a slider, and the slider is connected to the Z-axis moving mechanism 115 based on bolts, which is conducive to the Z-axis moving mechanism 115 being disassembled for maintenance when a failure occurs. The slider is embedded in the Y-axis moving rail 1161, and one side of the slider is connected to the output end of the third driving cylinder 1162, and the third driving cylinder 1162 is located above the Y-axis moving rail 1161. The slider is driven by the third driving cylinder 1162 to move along the positive direction of the Y axis on the Y-axis moving rail or move along the negative direction of the Y axis on the Y-axis moving rail. When the output end of the third driving cylinder 1162 moves along the positive direction of the Y-axis, it pushes the slider to move along the positive direction of the Y-axis on the Y-axis moving rail 1161, thereby driving the Z-axis moving mechanism 115 to move along the positive direction of the Y-axis, so that the loading push plate 114 approaches the detection part 12; when the output end of the third driving cylinder 1162 moves along the negative direction of the Y-axis, it pushes the slider to move along the negative direction of the Y-axis on the Y-axis moving rail 1161, thereby driving the Z-axis moving mechanism 115 to move along the negative direction of the Y-axis, so that the loading push plate 114 is away from the detection part 12, making it convenient for the loading push plate 114 to push the next rotor into the detection part.

[0052] Furthermore, the bottom of the partition 1141 fits with the V-shaped groove to form a cone, and a preset gap is formed between the partition 1141 and the V-shaped groove, ensuring that the partition 1141 maintains a preset distance from the V-shaped groove during the driving process, reducing the wear between the partition 1141 and the V-shaped groove, and extending the service life of the partition 1141.

[0053] Figure 7 The schematic diagram of the structure of the detection unit in the embodiment of the present invention is shown, and the detection unit 12 includes: a steering mechanism 121, a grabbing manipulator 122 and a detection camera 123; the steering mechanism 121 is located at the end of the lifting V-shaped groove 113, the grabbing manipulator 122 is located on the right side of the steering mechanism 121, and the detection camera 123 is located on the right side of the grabbing manipulator 122. The grabbing manipulator 122 is used to grab the rotor on the steering mechanism 121, and then transport it to the top of the detection camera 123, and transport the rotor to the next process according to the instruction.

[0054] Furthermore, the steering mechanism 121 is provided with a steering tool 1211 and a fourth driving cylinder 1212, and a rack is provided at the output end of the fourth driving cylinder 1212; a rotating gear is provided on one side of the steering tool 1211, and the rotating gear is meshed with the rack, and the length of the rack is one quarter of the outer gear ring of the rotating gear, so as to ensure that the rack can only drive the rotating gear to rotate 90° per stroke. When the output end of the fourth driving cylinder 1212 moves upward along the Z axis, it drives the rack to move upward, and the rack further drives the rotating gear to rotate counterclockwise, and the rotating gear rotates counterclockwise to drive the steering tool 1211 to rotate counterclockwise. In the process of the output end of the fourth driving cylinder 1212 moving upward to the end, the driven gear moves from the top of the rack to the bottom of the rack, and the driven gear rotates 90° counterclockwise, thereby driving the steering tooling 1211 to rotate 90° counterclockwise, so that the steering tooling 1211 is transformed from a state perpendicular to the ground plane to a state parallel to the ground plane.

[0055] Similarly, when the output end of the fourth driving cylinder 1212 moves along the negative direction of the Z axis, the rack is driven to move along the negative direction of the Z axis, and the rack further drives the rotating gear to rotate clockwise, and the rotating gear rotates counterclockwise to drive the steering fixture 1211 to rotate clockwise. In the process of the output end of the fourth driving cylinder 1212 moving downward to the end, the driven gear moves from the bottom of the rack to the top of the rack, and the driven gear rotates 90° clockwise, thereby driving the steering fixture 1211 to rotate 90° clockwise, so that the steering fixture 1211 is transformed from a state parallel to the ground plane to a state perpendicular to the ground plane.

[0056] Furthermore, the detection camera 123 is used to detect whether the rotor is the model currently being used on the production line and whether the appearance of the rotor meets the standards. When the detection camera 123 detects that the rotor is of the correct model and the appearance of the rotor meets the standards, it will send an electrical signal to the grasping robot 122, and the grasping robot 122 will transport the held rotor to the next process; on the contrary, when the detection camera 123 detects that the rotor is of the wrong model or detects that the appearance of the rotor does not meet the standards, it will send an electrical signal to the grasping robot 122, and the grasping robot 122 will transport the held rotor to the defective product area below the grasping robot 122.

[0057] The working principle of the rotor feeding device of the present invention is:

[0058] The height of the feed end of the loading track group 111 is adjusted by the height adjustment mechanism 112 so that there is a certain sliding height between the feed end and the discharge end. The deliveryman puts the rotor in from the feed end of the loading track group 111, and the rotors slide one by one along the sliding groove 1113 from the feed end of the loading track group 111 to the discharge end of the loading track group 111 under the action of gravity, and the first rotor at the discharge end of each loading track abuts against the vertical surface of the movable inclined plate. The induction switch detects that there is a rotor on the feeding rail and sends an electrical signal to the first driving cylinder 1133. The output end of the first driving cylinder 1133 moves along the negative direction of the Z axis, driving the movable inclined plate 1131 to move along the negative direction of the Z axis. When the movable inclined plate 1131 moves along the negative direction of the Z axis to be level with the bottom of the feeding rail group 111, the rotor located in the feeding rail group 111 moves from the sliding groove 1113 to the top of the movable inclined plate 1131, and only one rotor of each sub-feeding rail moves to the top of the movable inclined plate 1131. After the movable inclined plate 1131 pauses for a specified period of time at a position level with the bottom of the feeding rail group 111, the output end of the first driving cylinder 1133 moves in the positive direction along the Z-axis, driving the movable inclined plate 1131 and the five rotors located on the movable inclined plate 1131 to move upward. At the same time, the vertical surface of the movable inclined plate 1131 resists the rotor of the feeding rail group 111, so that the rotor of the feeding rail group 111 cannot slide onto the inclined surface of the movable inclined plate 1131. When the movable inclined plate 1131 moves in the positive direction along the Z axis until the top of the movable inclined plate 1131 is level with the top of the loading track, then the output end of the second driving cylinder 1152 moves in the negative direction along the Z axis, driving the loading push plate 114 to move in the negative direction of the Z axis on the Z-axis moving slide rail 1151, and then the output end of the third driving cylinder 1162 moves in the positive direction along the Y axis, thereby driving the Z-axis moving mechanism 115 and the loading push plate 114 to move in the positive direction along the Y axis. At the same time, the partition plate 1141 provided at the bottom of the loading push plate 114 abuts against the rotor, thereby pushing the rotor to move in the positive direction of the Y axis, so that the first rotor closest to the detection part enters the steering tooling 1211, and at the same time, the second rotor moves to the position of the original first rotor, the third rotor moves to the position of the original second rotor, the fourth rotor moves to the position of the original third rotor, and the fifth rotor moves to the position of the original fourth rotor. Then the output end of the fourth driving cylinder 1212 moves along the negative direction of the Z axis, driving the rack to move along the negative direction of the Z axis, thereby driving the rotating gear on the steering tooling 1211 to rotate 90° clockwise, thereby driving the steering tooling 1211 to rotate 90° clockwise, so that the steering tooling 1211 is perpendicular to the ground plane.The grabbing manipulator 122 moves to the steering fixture 1211 and grabs the rotor to the detection camera 123. After the detection camera 123 detects the rotor held by the grabbing manipulator 122, it sends an electrical signal to the grabbing manipulator 122, so that the grabbing manipulator 122 transports the rotor to the specified position. While the grabbing manipulator 122 transports the rotor, the output end of the fourth driving cylinder 1212 moves forward along the Z axis, driving the rack to move forward along the Z axis, and then driving the rotating gear on the steering fixture 1211 to rotate 90° counterclockwise, and then driving the steering fixture 1211 to rotate 90° counterclockwise to restore the steering fixture 1211 to its original position, that is, the steering fixture 1211 is parallel to the ground plane. Then, the output end of the second driving cylinder 1152 moves along the positive direction of the Z axis, driving the loading push plate 114 and the Z-axis moving mechanism 115 to move along the positive direction of the Z axis, and the output end of the third driving cylinder 1162 moves along the negative direction of the Y axis, thereby driving the Z-axis moving mechanism 115 and the loading push plate 114 to move along the negative direction of the Y axis. When the Z-axis moving mechanism 115 and the loading push plate 114 move to the head end of the Y-axis moving slide rail 1161, the output end of the second driving cylinder 1152 moves along the negative direction of the Z axis, driving the loading push plate 114 to move along the negative direction of the Y axis. The plate 114 moves in the negative direction along the Z axis, so that there are rotors in three of the four rotor accommodating areas close to the detection part, and then the output end of the third driving cylinder 1162 moves in the positive direction along the Y axis again, pushing the second rotor to the steering fixture 1211. At this time, the third rotor moves to the position of the original first rotor, the fourth rotor moves to the position of the original second rotor, and the fifth rotor moves to the position of the original third rotor. This cycle is repeated until the fifth rotor moves to the position of the original first rotor, and the fifth rotor is pushed to the steering fixture by the loading push plate 114. Then the output end of the second driving cylinder 1152 moves in the positive direction along the Z axis, driving the loading push plate 114 and the Z-axis moving mechanism 115 to move in the positive direction of the Z axis, and the output end of the third driving cylinder 1162 moves in the negative direction along the Y axis, thereby driving the Z-axis moving mechanism 115 and the loading push plate 114 to move in the negative direction along the Y axis and return to the original position. At this time, the output end of the first driving cylinder 1133 moves in the negative direction along the Z axis, driving the movable inclined plate 1131 to move in the negative direction along the Z axis until the top of the movable inclined plate 1131 is flush with the bottom of the feeding track group 11, so that the next batch of five rotors slide to the top of the movable inclined plate 1131.When the next batch of five rotors abut against the fixed inclined plate 1132, the output end of the first driving cylinder 1133 moves in the positive direction along the Z axis until the top of the movable inclined plate 1131 is flush with the top of the feeding track group 11, and then after the five rotors on the movable inclined plate 1131 are pushed to the steering tooling 1211 one by one, the output end of the first driving cylinder 1133 moves in the negative direction along the Z axis, driving the movable inclined plate 1131 to move in the negative direction of the Z axis, and then making the next batch of five rotors slide to the top of the movable inclined plate 1131, and this cycle continues until all the rotors are delivered to the steering tooling 1211.

[0059] Figure 8 The rotor pre-processing equipment in the embodiment of the present invention is shown, and the rotor pre-processing equipment comprises: a rotor feeding device 100 and a heating device 200, and the heating device 200 is arranged on one side of the detection part 12. The input end of the heating device 200 is located on one side of the detection camera 123, which is conducive to directly transporting the rotor to the input end of the heating device 200 after the detection step of the detection camera 123, thereby reducing the transportation time of the rotor and improving the efficiency of the production line.

[0060] Fig. 9 A structural schematic diagram of the heating device 200 in the present invention is shown, and the heating device 200 includes: a plurality of rotor positioning fixtures 21, a chain belt line 22 and a heating mechanism 23; the plurality of rotor positioning fixtures 21 are installed on the chain belt line 22, and the heating mechanism 23 is located above the chain belt line 22, and the heating mechanism 23 is driven by a fifth driving cylinder to move between the top of the rotor positioning fixture 21 and the bottom of the rotor positioning fixture 21.

[0061] Furthermore, the chain belt line 22 is driven by a first drive motor, and the output end of the first drive motor is movably connected to the driven gear on the chain belt line 22. When the output end of the first drive motor rotates, the driven gear on the chain belt line 22 is driven to rotate, thereby driving the chain belt line 22 to move forward.

[0062] Furthermore, when the first drive motor starts working, the output end of the first drive motor rotates one circle every certain time interval, thereby driving the driven gear to rotate 9°, so that the chain belt line 22 moves once every certain time, and the distance moved each time is equal.

[0063] Furthermore, a plurality of tooling plates 221 are provided on the chain belt line 22, and two rotor positioning toolings 21 are provided on any of the tooling plates 221. The plurality of tooling plates 221 are driven by the chain belt line 22 to move back and forth in the heating device 200, thereby driving the plurality of rotor positioning toolings 21 to move back and forth in the heating device 200.

[0064] Further, the heating mechanism 23 includes a plurality of heating coil groups 231. In this embodiment, the plurality of heating coil groups 231 are six groups, and one heating coil group 231 among the six heating coil groups 231 corresponds to one tooling plate 221 of the tooling plates 221 located on the six heating coils. Any of the heating coil groups 231 includes two heating coils, and the two heating coils on any of the heating coil groups 231 correspond to the two rotor positioning tools 21 on any of the tooling plates 221.

[0065] The preheating temperature of the several heating coil groups 231 gradually increases from the input end of the heating mechanism 23 to the output end of the heating mechanism 23, that is, the temperatures of the six coil groups are different, the temperature of the heating coil group 231 close to the input end of the heating mechanism 23 is the lowest, the temperature of the heating coil close to the output end of the heating mechanism 23 is the highest, and the temperature of the four heating coils located in the middle gradually increases from the input end of the heating mechanism 23 to the output end of the heating mechanism 23, ensuring that the rotor carries heat in the heating mechanism 23 and reduces heat loss in the rotor, so that the temperature of the rotor is still within the specified temperature range when entering the next process.

[0066] In summary, the embodiment of the present invention can simultaneously put multiple rotors on line by using the feeding track group, so that the rotor can slide into the lifting V-shaped groove by its own gravity on the feeding track, and the lifting V-shaped groove lifts the rotor to a specified height, and the feeding push plate moves back and forth above the lifting V-shaped groove to send the rotors on the lifting V-shaped groove to the rotor fixture one by one, and then the rotor fixture rotates at an angle to facilitate the grasping manipulator to transport the rotor from the rotor fixture to the detection mechanism to detect the rotor model and appearance, and finally transfer it to the next process. This method can speed up the feeding process at the feeding end, and at the same time, combined with the detection part at the discharging end, multiple rotors are formed into a group. The rotors in this group are pushed to the detection part one by one in a directional manner to complete the rotor detection process, so that the overall detection efficiency is improved. While ensuring that each rotor on line is of the correct model, the feeding rhythm of the feeding part and the detection rhythm of the detection part are consistent with the production rhythm of the production line, which effectively improves the production efficiency of the production line.
