Description

Technical Field

[0001] This invention relates to the field of motor assembly technology, and in particular to an automated assembly line for motor frames. Background Technology

[0002] Claw-pole stepper motors are a type of micro-motor widely used in smart home applications such as household appliances. A claw-pole motor mainly consists of: a housing assembly, rotor assembly, frame assembly, upper pole plate assembly, gear assembly, output shaft assembly, and cover plate assembly. For example... Figure 1 The diagram shows a split-type frame assembly 13. The frame assembly 13 includes an upper middle electrode plate 133, a lower middle electrode plate 134, an upper frame 131, and a lower frame 132. Both the upper middle electrode plate 133 and the lower middle electrode plate 134 are provided with a plurality of electrode claws 1301 arranged in a ring array. During the assembly process of the frame assembly 13, the upper middle electrode plate 133 and the lower middle electrode plate 134 need to be stacked to form a middle electrode plate assembly. Then, the upper frame 131 and the lower frame 132 are stacked to install the middle electrode plate assembly between the upper frame 131 and the lower frame 132. For this purpose, it is necessary to perform processes such as picking and placing materials, alignment, pressing, and gauge inspection of each component. It is also necessary to install terminals 1302 on the upper frame 131 and the lower frame 132 and guide and inspect them. Under normal circumstances, these processes need to be completed at different workstations, each with its own equipment and operators. The assembly of the frame components requires each part of the frame components to move between different workstations, which is time-consuming and affects the assembly efficiency of the motor frame. In addition, the intervention of manual operation may lead to poor product consistency, which is not conducive to mass production. Summary of the Invention

[0012] Compared with the prior art, the beneficial effects of the present invention are: Each tooling table on the transport platform reciprocates along a circular transport path. As it slides along this path, it sequentially passes through a skeleton feeding device, a pin feeding device, a pin shaping device, a pin detection device, two intermediate electrode plate feeding devices, a skeleton handling device, and a material handling and detection device. The skeleton feeding device places the upper and lower skeletons onto the first and second positioning posts on the tooling platform, respectively. Then, the tooling platform sequentially passes through the pin feeding device, pin shaping device, and pin detection device, performing pin feeding, pin shaping, and pin detection operations on the upper and lower skeletons. This avoids product quality instability caused by manual intervention and ensures that the terminals of the upper and lower skeletons meet standards. Afterward, the tooling platform sequentially passes through the two intermediate electrode plate feeding devices. Utilizing the alignment space on the first positioning post, the intermediate electrode plate feeding devices can accurately place the upper and lower intermediate electrode plates onto the first positioning post, ensuring the upper... The precise alignment of the middle and lower electrode plates avoids misalignment issues that may occur during manual assembly. After the upper and lower electrode plates are loaded, the tooling table passes through the skeleton transport device, which transfers the lower skeleton and fits it onto the first positioning post, allowing the upper and lower skeletons to overlap and form a skeleton assembly. Finally, the skeleton assembly is removed from the tooling table by the material handling and inspection device and subjected to gauge testing. After passing the gauge test, the material handling and inspection device places the skeleton assembly onto the working surface of the good product transport device for discharge. This automated assembly line, through the circular transport path and various devices on the transport table, enables the skeleton loading, pin loading, pin shaping, pin inspection, middle electrode plate loading, skeleton assembly, skeleton assembly material handling, and gauge testing to be performed on the same tooling table. This reduces manual intervention, has a high degree of automation, improves the assembly efficiency of the skeleton assembly, and ensures product quality consistency, meeting the needs of mass production.

Detailed Implementation

[0015] The present invention will be further described below with reference to the embodiments and accompanying drawings.

The automatic assembly line is used to automatically assemble a split frame assembly 13. The frame assembly 13 includes an upper middle electrode plate 133, a lower middle electrode plate 134, an upper frame 131, and a lower frame 132. The upper middle electrode plate 133 and the lower middle electrode plate 134 are each provided with a plurality of pole claws 1301 arranged in a ring array. The upper middle electrode plate 133 and the lower middle electrode plate 134 are stacked to form a middle electrode plate assembly. The upper frame 131 and the lower frame 132 are stacked to install the middle electrode plate assembly between the upper frame 131 and the lower frame 132.

[0017] The automated assembly line includes a transport platform 1, on which a circular transport path is provided, and several tooling tables 2 that slide along the circular transport path. The tooling tables 2 are provided with first positioning posts 201 and second positioning posts 202 arranged at intervals. The outer wall of the first positioning post 201 is provided with several partitions 204 arranged in a circular array. An alignment space 205 for the insertion of the pole claw 1301 is formed between two adjacent partitions 204.

[0018] One side of the circular transport path of the transport platform 1 is the processing side, and the other side of the circular transport path of the transport platform 1 is the circulation side. The processing side of the transport platform 1 is provided with a processing linear guide rail 101 for the tooling table 2 to slide, and a processing transport belt 102 for driving the tooling table 2 to slide along the processing linear guide rail 101. The circulation side of the transport platform 1 is provided with a circulation linear guide rail 103 for the tooling table 2 to slide, and a circulation transport belt 104 for driving the tooling table 2 to slide along the circulation linear guide rail 103. The transport direction of the processing transport belt 102 is opposite to the transport direction of the circulation transport belt 104.

[0019] A processing translation mechanism 105 and a circulation translation mechanism 106 are symmetrically arranged between the processing side and the circulation side of the transport table 1. Both the processing translation mechanism 105 and the circulation translation mechanism 106 are electric slides or electric push rods. The translation ends of the processing translation mechanism 105 and the circulation translation mechanism 106 are provided with switching linear guides 107 for the tooling table 2 to slide. The switching linear guides 107, the processing linear guides 101 and the circulation linear guides 103 are compatible.

The processing transport belt 102, the circulation transport belt 104, the processing translation mechanism 105 and the circulation translation mechanism 106 cooperate with each other to form a circular transport path of the transport table 1.

[0020] Both sides of the tooling table 2 are equipped with transmission blocks 203. The bottom surface of one transmission block 203 is in contact with the working surface of the processing conveyor belt 102, so that the processing conveyor belt 102 can drive the tooling table 2 to slide along the processing linear guide rail 101 through friction transmission. The bottom surface of the other transmission block 203 is in contact with the working surface of the circulating conveyor belt 104, so that the circulating conveyor belt 104 can drive the tooling table 2 to slide along the circulating linear guide rail 103 through friction transmission.

[0021] When the translation end of the machining translation mechanism 105 moves to the circulating linear guide 103, under the traction of the circulating conveyor belt 104, the tooling table 2 disengages from the circulating linear guide 103 and slides onto the switching linear guide 107 on the translation end of the machining translation mechanism 105. Then, the translation end of the machining translation mechanism 105 moves to the machining linear guide 101. Under the traction of the machining conveyor belt 102, the tooling table 2 disengages from the switching linear guide 107 on the translation end of the machining translation mechanism 105 and slides along the machining linear guide 101.

[0022] When the translation end of the cyclic translation mechanism 106 moves to the machining linear guide 101, under the traction of the machining conveyor belt 102, the tooling table 2 disengages from the machining linear guide 101 and slides onto the switching linear guide 107 on the translation end of the cyclic translation mechanism 106. Then, the translation end of the cyclic translation mechanism 106 moves to the cyclic linear guide 103. Under the traction of the cyclic conveyor belt 104, the tooling table 2 disengages from the switching linear guide 107 on the translation end of the cyclic translation mechanism 106 and slides along the cyclic linear guide 103.

Preferably, a plurality of stop telescopic mechanisms 10 are arranged along the length of the transport table 1 at the position between the processing transport belt 102 and the circulating transport belt 104. The skeleton feeding device 3, the pin feeding device 4, the pin shaping device 5, the pin detection device 6, the two middle electrode plate feeding devices 7, and the skeleton handling device 8 correspond to each stop telescopic device. The stop telescopic mechanism 10 is a telescopic cylinder or an electric push rod. The translation end of the stop telescopic mechanism 10 is provided with a stop head 11. Each stop head 11 is set towards the processing side of the transport table 1. The tooling table 2 is provided with a stop groove 206 for the stop head 11 to be inserted. When the tooling table 2 slides on the processing linear guide 101 to the corresponding device, the corresponding stop telescopic mechanism 10 drives the stop head 11 to extend and insert it into the stop groove 206 of the tooling table 2, thereby positioning the tooling table 2 to the corresponding device for operation. The transport platform 1 is also equipped with a controller 12, a skeleton feeding device 3, a pin feeding device 4, a pin shaping device 5, a pin detection device 6, two middle electrode plate feeding devices 7, a skeleton handling device 8, and a material picking and detection device 9, all of which are electrically connected to and controlled by the controller 12.

The skeleton feeding device 3 includes two skeleton vibrating plates 31 arranged at intervals, a skeleton feeding table 32, a skeleton feeding translation mechanism 33, a skeleton feeding lifting mechanism 34, and two skeleton clamping mechanisms 35 arranged at intervals. The two skeleton vibrating plates 31 vibrate to feed the upper skeleton 131 and the lower skeleton 132 respectively. A skeleton linear feeder 301 is provided between the skeleton vibrating plate 31 and the skeleton feeding table 32. The skeleton vibrating plate 31 and the skeleton linear feeder 301 are existing technologies and will not be described in detail here.

[0025] The skeleton feeding platform 32 is equipped with a skeleton distribution plate 302 and a skeleton distribution translation mechanism 304. The skeleton distribution plate 302 is provided with two skeleton feeding positions 303 arranged at intervals. The skeleton feeding positions 303 are groove structures. The two skeleton feeding positions 303 correspond to and are connected to the discharge ends of the two skeleton linear feeders 301, so that the upper skeleton 131 and lower skeleton 132 output from the discharge ends of the two skeleton linear feeders 301 enter the two skeleton feeding positions 303 respectively. The skeleton material distribution and translation mechanism 304 is a telescopic cylinder or an electric push rod. The translation end of the skeleton material distribution and translation mechanism 304 is connected to the skeleton material distribution plate 302, so that the skeleton material distribution and translation mechanism 304 drives the skeleton material distribution plate 302 to slide so that it corresponds to or is offset from the two skeleton linear feeders 301. When the skeleton material distribution plate 302 corresponds to the two skeleton linear feeders 301, the two skeleton linear feeders 301 respectively send the upper skeleton 131 and the lower skeleton 132 to the two skeleton loading positions 303 of the skeleton material distribution plate 302. After that, the skeleton The material distribution and translation mechanism 304 drives the skeleton material distribution plate 302 to translate so that it is offset from the two skeleton linear feeders 301. The skeleton loading and translation mechanism 33 and the skeleton loading and lifting mechanism 34 cooperate to adjust the position of the two skeleton clamping mechanisms 35, so that the two skeleton clamping mechanisms 35 move between the skeleton material distribution plate 302 and the corresponding tooling table 2. The two skeleton clamping mechanisms 35 respectively send the upper skeleton 131 and the lower skeleton 132 from the skeleton material distribution plate 302 to the first positioning post 201 and the second positioning post 202 of the corresponding tooling table 2.

The pin loading positions 403 include three groove structures arranged side by side. The number of groove structures in the pin loading positions 403 corresponds to the number of pin positions to be inserted in the upper frame 131 and the lower frame 132. The pin pushing and translating mechanism 43 is provided on the transport table 1. The translation end of the pin pushing and translating mechanism 43 is provided with two pusher members 404 arranged at intervals.

When the two pin feeding positions 403 of the pin feeding top plate 402 correspond to the discharge side of the pin linear feeder 401, the pin linear feeder 401 sends several terminals 1302 to the two pin feeding positions 403 respectively. The pin feeding lifting mechanism 44 drives the pin feeding top plate 402 to move upward so that the two pin feeding positions 403 correspond to the upper frame 131 and the lower frame 132 placed on the tooling table 2 respectively. The pin pushing translation mechanism 43 drives the two pushing parts 404 to move forward so that each terminal 1302 at the two pin feeding positions 403 is pressed into the pin-to-pin position of the upper frame 131 and the pin-to-pin position of the lower frame 132. Preferably, the pusher 404 is provided with two U-shaped pusher positioning frames 405. The two pusher positioning frames 405 move with the pusher 404 so that the two pusher positioning frames 405 respectively engage with the upper frame 131 and the lower frame 132, thereby positioning the upper frame 131 and the lower frame 132.

An inclined driving surface 502 is formed on the opposite side of 01. Three pin shaping slots 503 are also provided on the opposite side of the two shaping heads 501. The gap between the shaping lifting block 52 and the pin shaping table 51 allows the shaping head 501 to be inserted. A shaping roller 504 that abuts against the driving surface 502 is rotatably provided on the side of the shaping lifting block 52 away from the shaping head 501. When the pin shaping translation mechanism 53 drives the two shaping heads 501 forward, the driving surface 502 abuts against the corresponding shaping lifting block 52, so that the two shaping lifting blocks 52 move closer to each other and apply pressure to shape each pair of terminals 1302 located between them, ensuring that each terminal 1302 is straight.

[0029] The pin shaping strip is also equipped with a pin shaping pre-compression mechanism 505. The pin shaping pre-compression mechanism 505 is a telescopic cylinder or an electric push rod. The lifting end of the pin shaping pre-compression mechanism 505 is provided with two second skeleton positioning sleeves 506 at intervals. The two second skeleton positioning sleeves 506 are respectively sleeved and cooperated with the first positioning post 201 and the second positioning post 202. The two second skeleton positioning sleeves 506 press down on the upper skeleton 131 and the lower skeleton 132 respectively to prevent the upper skeleton 131 and the lower skeleton 132 from shaking during the pin insertion process.

[0030] refer to Figure 10 , Figure 11The pin detection device 6 is used to detect whether each terminal 1302 of the upper frame 131 and each terminal 1302 of the lower frame 132 is straight. The pin detection device 6 includes a pin detection platform 61, a pin detection translation mechanism 62, and a pin detection plate 63. The pin detection platform 61 is set on the transport platform 1, and the pin detection translation mechanism 62 is set on the pin detection platform 61. The pin detection translation mechanism 62 is a telescopic cylinder or an electric push rod. The pin detection plate 63 is set on the translation end of the pin detection translation mechanism 62. The pin detection plate 63 is provided with two pin detection ends 601 arranged at intervals. The two pin detection ends 601 correspond to the pin side of the upper frame 131 and the pin side of the lower frame 132, respectively. The pin detection end 601 includes four displacement sensors arranged in parallel. The space between two adjacent displacement sensors is the detection space for the terminal 1302 to be inserted so as to detect whether the terminal 1302 is leveled. When terminal 1302 is inserted into the inspection space, it can be determined whether terminal 1302 is straight by whether the displacement sensor is subjected to pressure displacement.

[0031] refer to Figure 12 The two middle electrode plate feeding devices 7 are used to feed the upper middle electrode plate 133 and the lower middle electrode plate 134 in sequence and put the upper middle electrode plate 133 and the lower middle electrode plate 134 into the first positioning post 201 of the tooling table 2 in sequence, so that the lower middle electrode plate 134 and the upper middle electrode plate 133 are stacked to form a middle electrode plate assembly. The intermediate plate feeding device 7 includes an intermediate plate vibratory plate 71, an intermediate plate feeding platform 72, an intermediate plate feeding translation mechanism 73, an intermediate plate feeding lifting mechanism 74, and an intermediate plate clamping mechanism 75. In one intermediate plate feeding device 7, the intermediate plate vibratory plate 71 vibrates to feed the upper intermediate plate 133, and in the other intermediate plate feeding device 7, the intermediate plate vibratory plate 71 vibrates to feed the lower intermediate plate 134. A linear feeder 701 is provided between the intermediate plate vibratory plate 71 and the intermediate plate feeding platform 72. Both the intermediate plate vibratory plate 71 and the linear feeder 701 are existing technologies and will not be described in detail here. The intermediate electrode plate loading platform 72 is set on the processing side of the transport platform 1. The intermediate electrode plate loading translation mechanism 73 is set on the intermediate electrode plate loading platform 72. The intermediate electrode plate loading lifting mechanism 74 is set on the translation end of the intermediate electrode plate loading translation mechanism 73. The intermediate electrode plate clamping mechanism 75 is set on the lifting end of the intermediate electrode plate loading lifting mechanism 74. Both the intermediate electrode plate loading translation mechanism 73 and the intermediate electrode plate loading lifting mechanism 74 are telescopic cylinders or electric push rods. The intermediate electrode plate clamping mechanism 75 is a pneumatic gripper. The intermediate electrode plate clamping mechanism 75 of one intermediate electrode plate loading device 7 clamps or releases the upper intermediate electrode plate 133, and the intermediate electrode plate clamping mechanism 75 of the other intermediate electrode plate loading device 7 clamps or releases the lower intermediate electrode plate 134.

[0032] The intermediate plate feeding platform 72 is equipped with an intermediate plate distribution plate 702 and an intermediate plate distribution and translation mechanism 703. The intermediate plate distribution plate 702 has an intermediate plate feeding position 704, which is a groove structure. The intermediate plate feeding position 704 corresponds to and is connected to the discharge end of the intermediate plate linear feeder 701, so that the upper intermediate plate 133 or lower intermediate plate 134 output by the intermediate plate linear feeder 701 enters the intermediate plate feeding position 704. The intermediate plate distribution and translation mechanism 703 is a telescopic cylinder or an electric push rod. The translation end of the intermediate plate distribution and translation mechanism 703 is connected to the intermediate plate distribution plate 702, so that the intermediate plate distribution and translation mechanism 703 drives the intermediate plate distribution plate 702 to slide so that it corresponds to or is offset from the intermediate plate linear feeder 701.

[0033] The tooling table 2 passes through two intermediate electrode plate loading devices 7 in sequence. The first intermediate electrode plate loading device 7 puts the upper intermediate electrode plate 133 onto the first positioning post 201 of the tooling table 2. Then, the second intermediate electrode plate loading device 7 puts the lower intermediate electrode plate 134 onto the second positioning post 202 of the tooling table 2 so that the lower intermediate electrode plate 134 and the upper intermediate electrode plate 133 can be stacked and assembled into an intermediate electrode plate assembly in subsequent operations.

[0034] When the middle plate distribution plate 702 of the first middle plate feeding device 7 corresponds to the middle plate linear feeder 701, the middle plate linear feeder 701 sends the upper middle plate 133 to the middle plate feeding position 704 of the middle plate distribution plate 702. Then, the middle plate distribution translation mechanism 703 drives the middle plate distribution plate 702 to translate so that it is offset from the middle plate linear feeder 701. The middle plate feeding translation mechanism 73 and the middle plate feeding lifting mechanism 74 cooperate to adjust the position of the middle plate clamping mechanism 75, so that the middle plate clamping mechanism 75 moves between the middle plate distribution plate 702 and the corresponding tooling table 2. The middle plate clamping mechanism 75 sends the upper middle plate 133 from the middle plate distribution plate 702 to the first positioning column 201 of the corresponding tooling table 2. When the middle plate distribution plate 702 of the second middle plate feeding device 7 corresponds to the middle plate linear feeder 701, the middle plate linear feeder 701 sends the lower middle plate 134 to the middle plate feeding position 704 of the middle plate distribution plate 702. Then, the middle plate distribution translation mechanism 703 drives the middle plate distribution plate 702 to translate so that it is offset from the middle plate linear feeder 701. The middle plate feeding translation mechanism 73 and the middle plate feeding lifting mechanism 74 cooperate to adjust the position of the middle plate clamping mechanism 75, so that the middle plate clamping mechanism 75 moves between the middle plate distribution plate 702 and the corresponding tooling table 2. The middle plate clamping mechanism 75 sends the lower middle plate 134 from the middle plate distribution plate 702 to the first positioning column 201 of the corresponding tooling table 2.

[0035] refer to Figure 13The skeleton transport device 8 is used to transfer the lower skeleton 132, which is sleeved on the second positioning post 202, and sleeve it onto the first positioning post 201, so that the upper skeleton 131 and the lower skeleton 132 are superimposed to form the skeleton assembly 13. The skeleton transport device 8 includes a skeleton transport platform 81, a skeleton transport translation mechanism 82, a skeleton transport lifting mechanism 83, and a skeleton transport clamping mechanism 84. The skeleton transport platform 81 is set on the transport platform 1. The skeleton transport translation mechanism 82 and the skeleton transport lifting mechanism 83 are both telescopic cylinders or electric push rods. The skeleton transport translation mechanism 82 is set on the skeleton transport platform 81, the skeleton transport lifting mechanism 83 is set on the translation end of the skeleton transport translation mechanism 82, and the skeleton transport clamping mechanism 84 is set on the lifting end of the skeleton transport lifting mechanism 83. The skeleton transport clamping mechanism 84 is a pneumatic gripper, which clamps or releases the lower skeleton 132.

[0036] The skeleton transport platform 81 is equipped with a first positioning and translation mechanism 801, a second positioning and translation mechanism 802, and a skeleton positioning frame 803. Both the first positioning and translation mechanism 801 and the second positioning and translation mechanism 802 are telescopic cylinders or electric push rods. The translation end of the first positioning and translation mechanism 801 is connected to the second positioning and translation mechanism 802, and the translation end of the second positioning and translation mechanism 802 is connected to the skeleton positioning frame 803. The first positioning and translation mechanism 801 and the second positioning and translation mechanism 802 cooperate to adjust the position of the skeleton positioning frame 803. The skeleton positioning frame 803 is used to lock the upper skeleton 131 to position the upper skeleton 131, so as to prevent the upper skeleton 131 from shaking during the process of the lower skeleton 132 being fitted into the first positioning post 201.

[0037] refer to Figure 14The material handling and inspection device 9 is used to remove the skeleton assembly 13 from the tooling table 2 and perform a gauge inspection. After the gauge inspection is qualified, the material handling and inspection device 9 places the skeleton assembly 13 onto the working surface of the good product handling device for discharge. The material handling and inspection device 9 includes a material handling and inspection table 91, a material handling translation mechanism 92, an inspection lifting mechanism 93, a gauge inspection column 94, a material handling lifting mechanism 95, a switching translation mechanism 96, a material handling rack 97, and a good product discharge mechanism 98. The material handling and inspection table 91 is set on the processing side of the transport table 1. The material handling translation mechanism 92 and the inspection lifting mechanism 93 are both telescopic cylinders or electric push rods. The material handling translation mechanism 92 is set on the material handling and inspection table 91. The inspection lifting mechanism 93 and the material handling lifting mechanism 95 are both set on the translation end of the material handling translation mechanism 92. The gauge inspection column 94 is set on the lifting end of the inspection lifting mechanism 93. The gauge inspection column 94 is used for gauge inspection of the skeleton assembly 13. The switching translation mechanism 96 is a telescopic cylinder or An electric push rod and a switching translation mechanism 96 are mounted on the lifting end of the material picking and lifting mechanism 95. A material picking rack 97 is mounted on the translation end of the switching translation mechanism 96. The material picking rack 97 is U-shaped and engages with the skeleton assembly 13, positioning or releasing the skeleton assembly 13 onto the gauge detection post 94. When the material picking rack 97 engages with the skeleton assembly 13, the gauge detection post 94 is inserted into the skeleton assembly 13. The material picking translation mechanism 92 moves the skeleton assembly 13 to a position above the good product discharge mechanism 98. The switching translation mechanism 96 then drives the material picking rack 97 to retract, allowing the skeleton assembly 13 to fall along the gauge detection post 94 onto the good product discharge mechanism 98 after release. The good product discharge mechanism 98 is a discharge hopper, which is existing technology and will not be described in detail here. For unqualified skeleton assemblies 13, they can be transferred to the circular transport path of the transport platform 1 for manual or mechanical recycling.

[0038] refer to Figures 1 to 14Each tooling table 2 on the transport platform 1 reciprocates along the circular transport path. As the tooling table 2 slides along the circular transport path, it passes sequentially through the skeleton feeding device 3, the pin feeding device 4, the pin shaping device 5, the pin detection device 6, the two middle electrode plate feeding devices 7, the skeleton handling device 8, the material picking and detection device 9, and the good product discharge mechanism 98. The skeleton feeding device 3 places the upper skeleton 131 and the lower skeleton 132 onto the first positioning post 201 and the second positioning post 202 on the tooling table 2, respectively. Then, the tooling table 2 passes sequentially through the pin feeding device 4, the pin shaping device 5, the two middle electrode plate feeding devices 7, the skeleton handling device 8, the material picking and detection device 9, and the good product discharge mechanism 98. The forming device 5 and the pin detection device 6 perform pin feeding, pin shaping, and pin detection operations on the upper frame 131 and lower frame 132, avoiding product quality instability caused by manual intervention and ensuring that each terminal 1302 of the upper frame 131 and each terminal 1302 of the lower frame 132 meets the standards. Afterwards, the tooling table 2 passes through two intermediate electrode plate feeding devices 7 in sequence. Utilizing the alignment spaces 205 on the first positioning post 201, the intermediate electrode plate feeding devices 7 can accurately feed the upper intermediate electrode plate 133 and the lower intermediate electrode plate 134. The upper and lower middle electrode plates 131 and 132 are fitted onto the first positioning post 201, ensuring the accuracy of the overlap between them and avoiding misalignment problems that may occur during manual assembly. After the upper and lower middle electrode plates 133 and 134 are loaded, the tooling table 2 passes through the skeleton transport device 8, which transfers the lower skeleton 132 and fits it onto the first positioning post 201, so that the upper skeleton 131 and the lower skeleton 132 overlap to form the skeleton assembly 13. Finally, the skeleton assembly 13 is removed from the tooling table 2 by the material removal and inspection device 9 and subjected to gauge inspection. After passing the test, the material handling and inspection device 9 places the skeleton assembly 13 onto the working surface of the good product handling device for discharge. This automatic assembly line, through the circular transport path on the transport table 1 and various devices, enables the skeleton feeding, pin feeding, pin shaping, pin inspection, middle electrode plate feeding, skeleton assembly, skeleton assembly 13 material handling and gauge inspection to be carried out on the same tooling table 2. This reduces manual intervention, has a high degree of automation, improves the assembly efficiency of the skeleton assembly 13, and also ensures the consistency of product quality, meeting the needs of mass production.

All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
