[0048] The following embodiments, in conjunction with the accompanying drawings, further illustrate specific implementations of the terminal block assembly device of the present invention. The terminal block assembly device of the present invention is not limited to the descriptions in the following embodiments.

[0049] The terminal block assembly equipment in this embodiment is mainly for assembling the relay housing and the terminal block. This terminal block assembly equipment enables automated assembly of the housing and the terminal block.

[0050] like Figure 1 The image shows the relay assembly equipment in the embodiment. Figure 2 The diagram shows the terminal block assembly equipment of this invention, including: a housing transmission line 1, a terminal block feeding module 2, a terminal block screw removal module 3, and a terminal block pushing module 4. In the figure, the direction indicated by the triangular arrow is the housing transmission direction of the housing transmission line 1.

[0051] In this embodiment, the housing transmission line 1 is used to transport housings (the housings of the terminal blocks). The housing transmission line 1 is provided with a terminal block assembly position, and a housing positioning device 11 is provided at the terminal block assembly position. The housing positioning device 11 is used to position the housings to facilitate the assembly of the terminal blocks. The housings on the housing transmission line 1 can be manually placed and fed.

[0052] In this embodiment, the terminal block feeding module 2 includes a feeding guide rail 21, through which the terminal blocks are sequentially fed. In one embodiment, the feeding guide rail 21 can be fed manually, or it can be fed through the terminal block hopper 25 and the terminal block feeding elevator 22. The feeding connection between the feeding elevator 22 and the feeding guide rail 21 can be achieved by the terminal block transfer module 23, which can be a robotic arm structure.

[0053] In this embodiment, the terminal block screw removal module 3 includes a screwdriver 31, a screwdriver tip pushing device 32, and a screwdriver tip drive motor 33, which is used to remove the screws from the terminal block.

[0054] In this embodiment, the terminal block pushing module 4 includes a terminal block positioning unit 40 and a terminal block pushing unit 41. The terminal block positioning unit 40 is used to dock with the feeding guide rail 21 and position the terminal block to the assembly position. The terminal block pushing unit 41 is used to push the terminal block at the assembly position into the housing.

[0055] In this embodiment, as Figure 2 and Figure 3 As shown, the terminal block positioning unit 40 includes a screw removal positioning component 401 and a terminal block discharge component 402. The screw removal positioning component 401 is connected to the feeding guide rail 21 and is used to position the transmitted terminal block. The terminal block discharge component 402 is used to discharge the terminal block after the screw removal is completed and send it to the terminal block push-in unit 41.

[0056] Furthermore, the screw removal positioning assembly 401 includes: a push block 4011, a push block driving device 4012, and a push block base 4013. The push block base 4013 has a retaining wall 4014 at one end corresponding to the feeding guide rail 21. The retaining wall 4014 has a screw removal positioning groove 4015 corresponding to the direction of the screwdriver 31. The shape of the screw removal positioning groove 4015 is adapted to the shape of the terminal block, which can limit the terminal block in multiple directions to prevent rotation during screw removal. The screw removal positioning groove 4015 is connected to the feeding guide rail 21. The push block 4011 is located on the discharge side of the screw removal positioning groove 4015 to block the continuous feeding of the terminal block 01, thereby limiting the position of the terminal block and facilitating the screw removal process. The push block 4011 is tractively connected to the push block drive device 4012. It is used to push the push block 4011 out so that it is misaligned with the screw-removing positioning groove 4015, or to retract the push block 4011 to close the discharge side of the screw-removing positioning groove 4015 and push the terminal block to the terminal block discharge assembly 402. In other words, besides positioning the terminal block 01, the push block 401, after being pushed out, leaves a space where a terminal block 01 can be pushed in. After retracting, it pushes the terminal block to the position of the terminal block discharge assembly 402. In this embodiment, the push block drive device 4012 can be cylinder-driven.

[0057] In this embodiment, the terminal block discharge assembly 402 includes: a discharge groove 4021 disposed on the push block base 4013 corresponding to the pushing direction of the push block 4011; discharge positioning blocks 4022 spaced apart from the discharge side of the screw unscrew positioning groove 4015; a discharge push rod (not shown in the figure); and a discharge driving device 4024. The terminal blocks in the discharge groove 4021 are pushed in one at a time when the push block 4011 retracts, and then discharged sequentially by the discharge push rod. In this embodiment, the discharge driving device 4024 can also be driven by a cylinder.

[0058] Furthermore, the retaining wall 4014 extends to one side of the discharge chute 4021, and the retaining wall 4014 is provided with a through hole through which the discharge push rod passes. The discharge driving device 4024 is disposed on the retaining wall 4014. The retaining wall 4014 can simultaneously assemble the discharge driving device 4024 and position one side of the discharge chute 4021.

[0059] In this embodiment, as Figure 4As shown, the connector pushing unit 41 includes: a pushing base 410, a pushing groove 413 disposed on the pushing base 410, a pre-pushing device 411 disposed on the upper part of one end of the pushing base 410, and a full-pushing device 415 disposed on the lower part of one end of the pushing base 410. The pushing groove 413 is connected to the discharge groove 4021 and is used to arrange and buffer the connectors. After three connectors are arranged, the pushing operation is performed. The use of the pre-pushing device 411 and the full-pushing device 415 in combination can reduce the possibility of connector jamming (such as misalignment) and damage to the machine. The pushing groove 413 can also be equipped with a sensor to detect whether the connector is in place. Once in place, a signal is sent to the pushing device to execute the pushing process.

[0060] In one specific implementation, a guide groove 412 is provided between the push-in groove 414 and the housing, and a guide push-in device 417 is provided at the bottom of the full push-in device 415. Since the terminal mounting grooves of the housing 02 are spaced apart, while the terminal blocks of the push-in groove 413 are tightly packed, direct pushing may cause jamming. Therefore, the guide groove 412 can smoothly and accurately guide the terminal blocks into the mounting grooves.

[0061] Furthermore, the full-push-in device 415 includes: a full-push-in drive device 4151, a full-push-in rod 4152, a push-in guide slider 4153, a push-in guide slide rail 4154, and a buffer spring 4155. The push-in guide slider 4153 is connected to the output shaft of the full-push-in drive device 4151, and the full-push-in rod 4152 is drivenly connected to the push-in guide slider 4153 through the buffer spring 4155. The push-in guide slider 4153 can keep the push-in process stable, while the buffer spring 4155 can prevent damage caused by hard push-in.

[0062] In this embodiment, combined with Figure 2 and Figure 4 As shown, the housing positioning device 11 includes: a housing positioning drive device 111 and a housing positioning block 112. The housing positioning block 112 is connected to the housing positioning drive device 111 in a transmission manner. The housing positioning block 112 is provided with positioning feet 113 corresponding to the inner cavity shape of the housing.

[0063] Furthermore, the housing positioning device 11 includes: a housing lower positioning drive device 115 and a housing lower positioning block 116, the housing lower positioning block 116 being connected to the housing lower positioning drive device 115 in a transmission manner, and the housing lower positioning block 116 being provided with a positioning support column 117 corresponding to the external shape of the housing.

[0064] Furthermore, in combination Figure 1As shown, the position of the housing can be detected by a first sensor 15 located near the housing positioning device 11. When the housing reaches the terminal assembly position, the sensor can detect its position, and then the housing positioning cylinder 111 can be controlled to drive the housing positioning block 112 to descend according to the sensor detection, thereby limiting the housing at the current position. The first sensor 15 can be an infrared, fiber optic, or vision sensor, etc.

[0065] In this embodiment, as Figure 5 As shown, the terminal block screw removal module 3 is also equipped with a proximity sensor 35 to detect the screw removal distance. When the screw removal reaches a suitable distance, the cutter head drive motor 33 stops working.

[0066] Furthermore, in this embodiment, after the circuit breaker housing is automatically assembled with the terminal block, the assembly of the lower guide plate can also be automated.

[0067] Specifically, such as Figure 1 As shown, the lower guide plate assembly follows the same housing transmission line 1 as the terminal block assembly, and the lower guide plate assembly position is located after the terminal block assembly position. The lower guide plate mounting module 5 includes: a lower guide plate vibratory plate 51, a lower guide plate conveying mechanism 52, a lower guide plate mounting mechanism 53, and a lower guide plate positioning device 54.

[0068] Furthermore, in this embodiment, after the circuit breaker housing is assembled with the terminal block and the lower guide plate, a product scanning module 6 is provided on the housing transmission line 1 after the lower guide plate assembly position to scan the product.

[0069] Furthermore, in this embodiment, after the circuit breaker housing is assembled with the terminal block and the lower guide plate, the assembly of the thermal element can also be automated.

[0070] Specifically, such as Figure 1 , Figure 6 and Figure 7 As shown, the basic modules for assembling thermal elements include: a housing transmission line 1, a thermal element handling module 7, and a thermal element assembly module 8. The housing transmission line 1 shares the same housing transmission line with the terminal block assembly and the thermal element assembly. The thermal element assembly position is located after the lower guide plate assembly position. Figure 6 The direction of the middle arrow indicates the housing transmission direction of housing transmission line 1.

[0071] In this embodiment, the housing transmission line 1 is used to transport the housing. The housing transmission line 1 is provided with a thermal element assembly position. A second housing positioning device 12 is provided at the thermal element assembly position. The thermal element assembly process can only be carried out after the housing is positioned by the second housing positioning device 12.

[0072] In this embodiment, the thermal element handling module 7 includes a handling guide rail 71 and a feeding drive device 78. The thermal element is mounted on the handling guide rail 71 by a carrier 70 and is sequentially transferred by the feeding drive device 78. The feeding drive device 78 can be cylinder driven. Each time the cylinder rod extends, the carrier 70 moves one position. Of course, depending on the amount assembled at one time, each time the cylinder rod extends, it can also move two or more positions.

[0073] Furthermore, the feeding of the transport guide rail 71 can be achieved through the hot element transfer unit 77 and the hot element feeder 75, with the hot element feeder supplying materials through the tray 751. Specifically, the tray 751 has a limiting groove structure designed for the shape of the hot element. The hot element is manually placed on the tray, oriented in a specific direction. The hot element transfer unit 77 typically employs a robotic arm structure to grip the hot element on the tray, thus transferring the hot element to the feeding end of the transport guide rail 71.

[0074] In this embodiment, the thermal element assembly module 8 includes a thermal element clamping unit 81 and a thermal element transfer unit 82. The thermal element clamping unit 81 is connected to the thermal element transfer unit 82 in a transmission manner. The thermal element clamping unit 81 is used to clamp the thermal element on the transport guide rail 71, and the thermal element transfer unit 82 is used to move the thermal element to the thermal element assembly position.

[0075] Furthermore, such as Figure 8 As shown, the heat element clamping unit 81 includes a heat element clamping claw 811, a clamping cylinder 812, and a heat element lifting cylinder 813. The clamping cylinder 812 is operatively connected to the heat element lifting cylinder 813, and the heat element lifting cylinder 813 is operatively connected to the heat element transfer unit 82.

[0076] Furthermore, the heat element transfer unit 82 includes a linear slide rail 821 corresponding to the heat element assembly position and a slider 822 disposed on the linear slide rail 821, and the heat element upper and lower cylinders 813 are fixedly disposed on the slider 822.

[0077] In this embodiment, if material is fed manually directly onto the transport guide rail 71, both the carrier and the heating element must be fed simultaneously, making it difficult to control the efficiency and accuracy of material feeding. In this embodiment, if... Figure 1 As shown, the thermal element handling module 7 also includes a carrier feeding unit 73 disposed at the feeding end of the handling guide rail 71, through which carrier feeding is performed.

[0078] As a specific implementation method, such as Figure 9As shown, the carrier feeding unit 73 includes: a carrier feeding transmission rail 730, a transmission rail driving device 732, and a carrier lifting device 733. The carrier feeding transmission rail 730 can be belt driven or roller driven. In this embodiment, a belt pulley structure is preferred, which has a relatively flat transmission surface to ensure that the positional accuracy of the carrier is controllable. The discharge end of the carrier feeding and transmission rail 730 is located below the feed end of the transport guide rail 71. The feeding drive device 78 is spaced apart from the feed end of the transport guide rail 71 to leave space for the carrier to load materials. The carrier lifting device 733 includes a carrier lifting drive device 7331 and a carrier lifting bracket 7332. The carrier lifting bracket 7332 is located corresponding to the discharge end of the carrier feeding and transmission rail 730 and is used to lift the carrier to the track plane of the transport guide rail 71. Then, the feeding drive device 78 pushes the carrier to move one body position, pushing the carrier out of the carrier lifting bracket 7332 to the track surface of the transport guide rail 71. The carrier lifting bracket 7332 then descends back to its original position.

[0079] Furthermore, the inlet end of the carrier feeding conveyor rail 730 is located below the outlet end of the conveying guide rail 71. The thermal element conveying module 7 also includes a carrier return unit 74 located at the outlet end of the conveying guide rail 71, used to return the carrier to the inlet end of the carrier feeding conveyor rail 730. By returning the carrier to the inlet end of the carrier feeding conveyor rail 730 through the carrier return unit 74, the carrier can be reused cyclically, eliminating the need for a separate carrier hopper and recycling hopper, thus reducing device cost and the number of carriers required.

[0080] Furthermore, the carrier return unit 74 includes a return bracket 741 disposed at the discharge end of the transport guide rail 71 and a return drive device 742 pulverizedly connected to the return bracket 741. The return bracket 741 has a U-shaped structure. After the carrier reaches the discharge end of the transport guide rail 71, both ends of the carrier enter the return bracket 741. At this time, the carrier disengages from the track surface of the transport guide rail 71. The return bracket 741 is driven to descend by the return drive device 742, placing the carrier at the inlet end of the carrier feeding transmission rail 730. The carrier is then transported to the discharge end through the carrier feeding transmission rail 730, thus forming a cycle of carrier use.

[0081] In this embodiment, due to the structural characteristics of the thermal element, although a carrier provides limiting, in order to achieve the thermal element clamping action, the carrier can only limit the bottom to a limited extent. Therefore, it is difficult for the carrier to achieve accurate posture uniformity during the movement and transmission process of the transport guide 71, which makes it difficult for the thermal element clamping unit 81 to accurately clamp the thermal element. Therefore, as Figure 9 and Figure 10As shown, in this embodiment, a thermal element attitude adjustment mechanism 76 is provided at the discharge end of the conveying guide rail 71 to adjust the attitude of the thermal element at the clamping position, so that the thermal element clamping unit 81 can clamp it smoothly.

[0082] In one specific implementation, the thermal element attitude adjustment mechanism 76 includes: a V-shaped guide block 761 corresponding to the first end of the thermal element, a guide block driving device 762 connected to the V-shaped guide block 761, an adjusting gripper 763 corresponding to the second end of the thermal element, an adjusting gripper driving device 764, and an adjusting gripper lifting driving device 765.

[0083] In this embodiment, the hot element loading machine 75 includes a loading conveyor line 750 and a material tray 751. As can be seen from the above, the structural characteristics of hot elements make it difficult to place them upright effectively. At the same time, the carrier cannot effectively limit their position. Therefore, in order to achieve rapid placement and transfer of hot elements, the material tray 751 adopts a method in which the hot elements are placed flat in the limiting groove of the material tray 751 to improve the speed of manual loading and the efficiency of feeding.

[0084] Please refer to Figure 6 and Figure 7 As shown, since the heat element is installed vertically onto the housing, the heat element clamping unit 81 also needs to clamp the upper part of the heat element to complete the installation process. Therefore, as... Figure 11 As shown, the thermal element transfer unit 77 of this embodiment includes: a transfer gripper assembly 771, a transfer gripper rotation drive device 772, and a transfer gripper lifting drive device 773. The thermal element is rotated 90° by the transfer gripper rotation drive device 742 before being placed in the carrier, which can facilitate the transportation and subsequent installation of the thermal element in the carrier.

[0085] like Figure 12 As shown, the second housing positioning device 12 includes a positioning clamp 121 disposed on one side of the housing transmission line 1 and a second positioning cylinder 122 that is pulsatorically connected to the positioning clamp 121.

[0086] Furthermore, the second housing positioning device 12 also includes a lifting chuck 123 disposed at the bottom of the housing transmission line 1 and a lifting cylinder 124 that is pulsatorically connected to the lifting chuck 123.

[0087] In this embodiment, after the thermal element assembly is completed, a thermal element pressing device 90, a quality inspection device 91, and a defective part sorting device 92 are also provided after the thermal element assembly position.

[0088] Based on the above-described terminal block assembly equipment, lower guide plate assembly equipment, and thermal element assembly equipment, the assembly process of the relay assembly equipment in this embodiment is as follows:

[0089] S1, Start

[0090] S2, the product casing is manually placed at the inlet of casing transmission line 1 and flows to the terminal block installation position. The terminal blocks are fed to the terminal block unscrew module by the feeding elevator 22. The terminal blocks with unscrewed screws are stored in the push-in material trough 413. When a certain number of terminal blocks are gathered, they are pushed into the product in groups of three. After the action is completed, the product flows to S3.

[0091] S3: The product flows to the lower guide plate assembly module for automatic assembly of the lower guide plate. After the action is completed, the product flows to S4.

[0092] S4, the product flows to the assembly position of the thermal element assembly equipment. The thermal elements are provided by the thermal element feeder 75 and are transferred and buffered by the carrier return flow. After reaching the picking position, the thermal element assembly module 8 loads the thermal elements into the housing. After loading 3 thermal elements in sequence, the product flows to S6.

[0093] As the S5 product flows to the thermal element assembly module 8, the product scanning module 6 simultaneously scans the product code.

[0094] S6 products flow to the heat element pressing device 90 and the quality inspection device 91 (CCD module). After the upper and lower pressing cylinders press the heat element, the assembly status of the internal components of the product is inspected by CCD vision and sent to the PLC. After the action is completed, the product flows to S7.

[0095] S7 products flow to the defective product discharge module. Based on the signal given by S6, defective products are rejected, and qualified products flow out via the conveyor belt.

[0096] S8 has ended.
