Description

Technical Field

[0001] This invention patent relates to radar controller assembly, specifically to a controller assembly system. Background Technology

[0002] Vehicle radar typically consists of sensors, a controller, and wiring harnesses. The sensors are mounted on the front or rear bumper of the vehicle, while the controller is mounted on the vehicle body. The sensors emit and receive ultrasonic waves, while the controller receives the signals emitted by the sensors and performs calculations to allow the driver to monitor the situation in front of and behind the vehicle, thus preventing collisions with obstacles.

[0003] The patent document entitled "Vehicle Controller" (document number CN218352873U) discloses a technical solution including a housing, a side cover, and a circuit board; the housing and side cover are detachably installed together, and the circuit board is located inside the housing; a second slot is provided on each of the two opposite inner side walls of the housing, and the end of the circuit board is located in the mating groove of the second slot, the groove width of the second slot being slightly larger than the thickness of the circuit board. The vehicle controller has a second slot on the inside of the housing, and the circuit board is assembled into the housing through the second slot.

[0004] The patent document entitled "Main Controller for Radar Probe" (document number CN212723312U) discloses a technical solution including a housing having a cavity and an opening at one end, a circuit board assembled in the cavity of the housing, and an electrical connector that is inserted into the cavity from the opening of the housing and connected to the circuit board.

[0005] like Figure 1 As shown in Figure 2, the controller S mainly consists of a controller housing B, a controller circuit board A, and a cover C. During production, the controller circuit board A is first programmed. After programming, the circuit board A is inserted into the controller housing B through its opening, and the cover C is placed on top. Finally, the electrical connection of the terminals D on the controller S connected to the controller circuit board A is tested to check if the controller S functions correctly. In existing technologies, controller assembly processes are typically set up independently, and some assembly operations are still performed manually. The loading, unloading, assembly, and even transportation between these processes consume significant labor costs, and production efficiency is also affected by the efficiency of manual operation, hindering the improvement of controller assembly efficiency. Currently, there is a lack of a complete assembly line for radar controllers to solve these problems. Summary of the Invention

[0006] This invention provides a controller assembly system that can automatically assemble controller circuit boards, controller housings, and housing covers, improving controller assembly efficiency, and simultaneously performing electrical connection tests on the assembled controller.

[0007] To achieve the above objectives, the technical solution adopted is as follows: a controller assembly system, wherein a horizontally placed conveyor belt is provided on the workbench, and a programming unit, an insertion unit, a capping unit, and a testing unit are arranged sequentially from upstream to downstream of the conveyor belt on the workbench. A tray for supporting the controller circuit board and the controller housing is provided on the conveyor belt, wherein:

[0008] The programming unit is used to program the controller circuit board.

[0009] Insertion unit, used to place the controller circuit board into the controller housing;

[0010] A cover unit is used to cover the opening of a controller housing containing a controller circuit board.

[0011] The test unit is used to perform electrical connection tests on the terminals on the controller. The controller is composed of a controller circuit board, a controller housing, and a housing cover.

[0012] Compared with the prior art, the technical advantages of this invention are as follows: the burning unit, insertion unit, capping unit and testing unit are arranged sequentially from upstream to downstream of the conveyor belt on the workbench. The controller circuit board, controller box and box cover that constitute the controller can be conveyed to the corresponding unit by the conveyor belt for burning, insertion, capping and testing in sequence. The system can complete a whole set of assembly and testing operations of the controller, greatly reducing the steps that require manual operation. At the same time, the various processes are closely connected to each other and are orderly, making product transfer more convenient and helping to improve the assembly efficiency of the controller.

[0039] The following is in conjunction with the appendix Figure 1-24 The present invention will be further described in detail below, including related content:

[0040] A controller assembly system includes a workbench 100 with a horizontally positioned conveyor belt 200. A programming unit 300, an insertion unit 400, a capping unit 500, and a testing unit 600 are sequentially arranged on the workbench 100 from upstream to downstream of the conveyor belt 200. The conveyor belt 200 has a tray 700 for supporting a controller circuit board A and a controller housing B. Specifically: the programming unit 300 programs the controller circuit board A; the insertion unit 400 inserts the controller circuit board A into the controller housing B; the capping unit 500 covers the opening of the controller housing B containing the controller circuit board A with a cover C; and the testing unit 600 performs electrical connection tests on the terminals D of the controller S. The controller S is composed of the controller circuit board A, the controller housing B, and the cover C.

[0041] In the above scheme, the workbench 100 is arranged with the burning unit 300, the insertion unit 400, the capping unit 500, and the testing unit 600 arranged sequentially from upstream to downstream of the conveyor belt 200. The controller circuit board A, controller box B, and box cover C that constitute the controller S are transported sequentially by the conveyor belt 200 to the corresponding units for burning, insertion, capping, and testing, thereby completing a complete set of assembly and testing operations for the controller S. The various workstations are closely connected to each other and proceed in an orderly manner, making product transfer more convenient and improving the assembly efficiency of the controller S.

[0042] It should be noted that the purpose of tray 700 is to support the controller circuit board A and controller housing B as they move to their respective assembly stations. The housing cover C does not need to be supported by tray 700 when it enters the capping unit 500. This is because the assembly operation between controller housing B and housing cover C is the final step before testing. Before capping, tray 700 does not need to support housing cover C; a separate loading structure for housing cover C can be provided at the capping unit 600. Alternatively, the controller circuit board A, controller housing B, and housing cover C can all be placed directly on tray 700 upstream of the programming unit 300.

[0043] Combination Figure 5-8As shown, as a preferred embodiment, the programming unit 300 includes a stage 310, on which a placement area for carrying the controller circuit board A is provided, and the placement area is provided with a programming probe 320 for abutting the programming contacts at the bottom of the controller circuit board A. A clamping unit 330 is provided above the placement area of ​​the controller circuit board A. A first driving unit 340 drives the clamping unit 330 to move down to a limiting position on the upper surface of the controller circuit board A, or drives the clamping unit 330 to move up and to a clearance position where the clamping unit 330 is misaligned with the area above the upper surface of the controller circuit board A.

[0044] In this scheme, during the programming of controller circuit board A, controller circuit board A is placed in the placement area on the stage 310 (the programming probe 320 set in the placement area abuts against the programming contacts on the lower surface of controller circuit board A to program the controller circuit board A). The first drive unit 340 can drive the clamping unit 330 to move downward, so that the clamping unit 330 presses the controller circuit board A on the stage 310 to ensure the stability of controller circuit board A during the programming process. Conversely, the first drive unit 340 can drive the press unit 330 to move upward, so as to release the clamping effect on controller circuit board A, so that the programmed controller circuit board A can be removed from the stage 310.

[0045] Furthermore, the first drive unit 340 can also drive the clamping unit 330 to rotate to a misaligned position with the area above the controller circuit board A on the platform 310, ensuring that the area above the controller circuit board A is unobstructed, thus facilitating the placement and removal of the controller circuit board A on the platform 310. Because the clamping unit 330 is misaligned with the area above the controller circuit board A on the platform 310, this arrangement facilitates the placement of a robotic arm for loading or unloading the controller circuit board A in the platform 310. The clamping unit 330 will not interfere with the movement of the robotic arm, and it also helps simplify the robotic arm's movement path, improving the overall operating efficiency of the equipment.

[0046] In detail, in the prior art, the controller circuit board A needs to be placed flat on the stage 310 during the programming process. The controller circuit board A is generally small and thin. The robot usually uses a suction cup to pick up the controller circuit board A. Therefore, if the clamping unit 330 is always kept above the surface of the controller circuit board A on the stage 310, it is necessary to consider whether the robot component located above the surface of the controller circuit board A will interfere with the clamping unit 330.

[0047] Furthermore, the lower end of the platform 310 is provided with a stand 350, on which a first telescopic cylinder 341 is provided. The piston rod of the first telescopic cylinder 341 is located in the vertical direction and the rod end is connected to a mounting plate 342. A rotary cylinder 343 is provided on the mounting plate 342. The rotation shaft of the rotary cylinder 343 is located in the vertical direction and the shaft end is connected to a clamping unit 330. In this scheme, the first telescopic cylinder 341 can drive the mounting plate 342 and the rotary cylinder 343 thereon to move up and down together, thereby causing the clamping unit 330 connected to the shaft end of the rotary cylinder 343 to move up and down to clamp the controller circuit board A placed on the platform 310; while the rotary cylinder 343 can drive the clamping unit 330 to rotate around the rotation axis of the rotary cylinder 343, thereby causing the clamping unit 330 to rotate to a clearance position that is misaligned with the area above the surface of the controller circuit board A, so that the robot arm can pick up the burned controller circuit board A from the platform 310 or pick up the controller circuit board A to be burned and place it on the platform 310.

[0048] The rotary cylinder 343 has a connecting arm 344 that extends radially to its rotating shaft end, and the clamping unit 330 is connected to the extended end of the connecting arm 344. The connecting arm 344 serves as a transitional connector between the clamping unit 330 and the rotary cylinder 343, ensuring that the cylinder body of the rotary cylinder 343 avoids reasonable clearance from the controller circuit board A, while allowing the clamping unit 330 to press against the controller circuit board A.

[0049] Additionally, it should be noted that the programming unit 300 also includes a first feeding and conveying unit 360. A first gripping unit 370 grips the controller circuit board A to be programmed from the first feeding and conveying unit 360 and moves it to the placement area on the platform 310, or grips a already programmed controller circuit board A from the placement area and moves it to the tray 700 on the conveyor belt 200. The first feeding and conveying unit 360 can transport the controller circuit board A to be programmed, and the first gripping unit 370 enables the loading and unloading of materials from the platform 310.

[0050] Combination Figure 9 and Figure 10As shown, in a preferred embodiment, the insertion unit 400 includes a pushing unit 410. A flat tray 700 is provided with a guide groove 710 for accommodating the controller circuit board A and a receiving groove 720 for accommodating the controller box B. The controller circuit board A, placed in the guide groove 710, is horizontally arranged. The controller box B is a flat rectangular box with an opening on one side. The large top and bottom surfaces of the controller box B are horizontally arranged on the receiving groove 720. The opening of the controller box B is located at one end of the guide groove 710, and the depth direction of the controller box B cavity is consistent with the extension direction of the guide groove 710. The controller circuit board A and the opening of the controller box B are arranged opposite each other in the length direction of the guide groove 710. The pushing unit 410 pushes the controller circuit board A placed on the guide groove 710 and moves it along the length direction of the guide groove 710 into the controller box B.

[0051] In this design, the controller circuit board A, programmed by the programming unit 300, is placed in the guide groove 710 on the tray 700, while the controller housing B is placed in the receiving groove 720 on the tray 700. The openings of the controller circuit board A and the controller housing B are arranged opposite each other along the length of the guide groove 710. The push unit 410 pushes the controller circuit board A, placed on the guide groove 710, to move it along the length of the guide groove 710 into the controller housing B, thereby quickly completing the insertion operation between the controller circuit board A and the controller housing B. After assembly, the push unit 410 can be reversed and reset.

[0052] It should be noted that the guide groove 710 has a guiding and limiting function for the controller circuit board A placed therein. When the pushing unit 410 pushes the controller circuit board A placed on the guide groove 710, the controller circuit board A moves along the length of the guide groove 710 under the guiding and limiting function of the guide groove 710.

[0053] Furthermore, the pushing unit 410 includes a push plate 411, which is located at the end of the guide groove 710 away from the receiving groove 720. The surface of the push plate 411 is perpendicular to the length direction of the guide groove 710, and the moving path of the push plate 411 is within the cavity of the guide groove 710. The second driving unit 412 drives the push plate 411 to push the controller circuit board A into the controller housing B along the length direction of the guide groove 710 or drives the push plate 411 to reset to the initial position that avoids the placement area of ​​the controller circuit board A on the guide groove 710.

[0054] The second drive unit 412 can be a telescopic cylinder, with the piston rod core direction parallel to the groove length direction of the guide groove 710 and the rod end connected to the push plate 411. The telescopic cylinder can be used to extend and retract to make the push plate 411 move along the groove length direction of the guide groove 710, thereby pushing the controller circuit board A placed in the guide groove 710 to move.

[0055] The push plate 411 is perpendicular to the length of the guide groove 710. This is to ensure that the force distribution on the controller circuit board A is uniform when the push plate 411 pushes against it, thus guaranteeing that the controller circuit board A slides stably within the guide groove 710 without tilting. Furthermore, the movement path of the push plate 411 is located within the cavity of the guide groove 710. This design also ensures that when the push plate 411 pushes against the controller circuit board A, its body can move within the cavity of the guide groove 710 without interfering with the groove wall or bottom.

[0056] A guide seat 710A is connected to the upper surface of the pallet 700. A guide groove 710 is formed on the upper surface of the guide seat 710A, with the groove opening facing upwards and the groove length direction located horizontally. The two ends of the guide groove 710 in the groove length direction pass through the opposite side surfaces of the guide seat 710A. This design further restricts the arrangement of the guide groove 710, placing it on the guide seat 710A on the pallet 700 instead of directly on the pallet body, resulting in a more rational structural design.

[0057] Additionally, the insertion unit 400 also includes a second feeding and conveying unit 420. When the conveyor belt 200 conveys the tray 700 to the insertion unit 400, the second gripping unit 430 grips the controller housing B on the second feeding and conveying unit 420 and moves it into the receiving groove 720, or grips the pre-programmed controller circuit board A and moves it into the guide groove 710. The second feeding and conveying unit 420 is used to convey the controller housing B to be assembled, and the second gripping unit 430 is used to grip the controller housing B and move it into the receiving groove 720 so that it can be inserted into the pre-programmed controller circuit board A located in the guide groove 710.

[0058] Combination Figure 11-18 As shown, as a preferred embodiment, the cover unit 500 includes a cover clamping mechanism 510. A positioning groove 730 for accommodating the controller box B is provided on the flat tray 700. The controller box B contains a controller circuit board A. The controller box B is a flat rectangular box with an opening on one side and a circuit board inside. The controller box B placed in the vertical positioning groove 730 has its opening facing upwards.

[0059] When the conveyor belt 200 conveys the pallet 700 to the position of the capping unit 500, the lid clamping mechanism 510 is located above the pallet 700. The lid clamping mechanism 510 clamps the flat lid C, and the lid C and the opening of the controller box B in the positioning groove 730 are arranged vertically opposite each other. The lower end edge of the lid C is connected to a claw C1 extending into the cavity of the controller box B. The drive mechanism drives the lid clamping mechanism 510 to move down along the depth direction of the cavity of the controller box B to the termination position where the claw C1 and the snap-fit ​​hole B11 on the controller box B snap-fit ​​each other, or releases the clamping effect on the lid C and drives the lid clamping mechanism 510 to move upward and reset to the initial position.

[0060] In this solution, during the assembly of the controller box B and the cover C, the insertion unit 400 inserts the controller circuit board A into the controller box B, and then places the controller box B in the positioning groove 730 on the tray 700 with the opening facing upwards to position the controller box B. The cover C, held by the cover clamping mechanism 510, is in a flat state. Subsequently, the drive mechanism drives the cover clamping mechanism 510 to move along the depth direction of the controller box B cavity towards the opening of the controller box B placed on the tray 700 until the claw C1 on the cover C engages with the snap-fit ​​hole B11 on the controller box B, thus realizing the automatic assembly operation between the cover C and the controller box B.

[0061] After the claw C1 on the cover C engages with the snap-fit ​​hole B11 on the controller body B, the drive mechanism releases the clamping action of the cover clamping mechanism 510 on the cover C and drives the cover clamping mechanism 510 to move upward and reset to the initial position, so that the above assembly operation can be repeated for the controller body B and the cover C.

[0062] Furthermore, the lid clamping mechanism 510 includes a support frame 511 with its frame surface flat. When the support frame 511 is in the initial position, it supports the edge of the lid C, and the claw C1 and the support frame 511 are in a position of mutual avoidance. When the pressing mechanism 512 above the support frame 511 moves downward and presses against the upper surface of the lid C on the support frame 511, the pressing mechanism 512 and the support frame 511 move downward synchronously along the depth direction of the controller box B until the claw C1 is inserted into the controller. The guide groove B1, vertically arranged on the inner wall of box B, stops at the stop position; when the support frame 511 is in the stop position, the frame area of ​​the support frame 511 expands and separates from the box cover C, and the pressing mechanism 512 presses the box cover C down to the termination position where the claw C1 and the locking hole B11 at the lower end of the guide groove B1 are engaged with each other; after the claw C1 and the locking hole B11 are engaged with each other, the support frame 511 and the pressing mechanism 512 move up and reset, and the frame area of ​​the support frame 511 shrinks back to the initial size of the support box cover C.

[0063] In this design, initially, the lid C is placed on the support frame 511, which supports the edge of the lid C, with the claw C1 positioned within the frame area of ​​the support frame 511. Subsequently, the pressing mechanism 512 above the support frame 511 moves downwards and presses against the upper surface of the lid C on the support frame 511. The pressing mechanism 512 and the support frame 511 cooperate to clamp the lid C. As the pressing mechanism 512 and the support frame 511 move downwards synchronously along the depth direction of the controller housing B, they carry the lid C towards the opening of the controller housing B until the claw C1 on the lid C inserts into the vertically arranged guide groove B1 on the inner wall of the controller housing B. At this point, the support frame 511 expands, thus separating from the cover C (because the claw C1 has been inserted into the guide groove B1 on the inner wall of the controller housing B. Under the constraint of the guide groove B1 on the claw C1, even without the support of the support frame 511, the cover C can maintain a flat posture and move along the length of the guide groove B1 without tilting), preventing the support frame 511 from interfering with the closing of the cover C and the opening of the controller housing B. After the support frame 511 separates from the cover C, the holding mechanism 512 continues to move downward, thereby pushing the cover C to close on the opening of the controller housing B. At the same time, the claw C1 will also engage with the snap-fit ​​hole B11 at the lower end of the guide groove B1, realizing the assembly operation between the cover C and the controller housing B.

[0064] After the above operations are completed, the support frame 511 and the pressing mechanism 512 move upward and reset, and the frame area of ​​the support frame 511 retracts to the initial size of supporting the edge of the lid C. The size of the frame area of ​​the support frame 511 determines whether the support frame 511 can support the lid C. When the frame area of ​​the support frame 511 is in the tightened state, the support frame 511 surrounds the outer periphery of the lid C and supports the edge of the lid C to prevent the lid C from falling downward. When the frame area of ​​the support frame 511 is in the expanded state, the frame of the support frame 511 cannot be maintained below the edge of the lid C. There is no interference between the lid C and the support frame 511 when they move up and down relative to each other, so as not to affect the pressing mechanism 512 from continuing to push the lid C downward to close the opening of the controller box B.

[0065] Furthermore, the support frame 511 is a square frame structure composed of two U-shaped support rods 5111 with their openings facing each other. The rod bodies of the two support rods 5111 are located on the horizontal plane and their ends are connected to each other. The area enclosed by the inner rod surfaces of the two support rods 5111 constitutes the cavity 5112 for accommodating the lid C. The opposite side rod surfaces between the two support rods 5111 are provided with a platform edge 5113 protruding towards the center of the cavity 5112 and the platform edge 5113 is arranged along the cover edge of the lid C. The cover edge of the lid C located in the cavity 5112 rests on the upper end surface of the platform edge 5113. When the support frame 511 is in the stop position, the drive mechanism drives the two support rods 5111 to move away from each other and the platform edge 5113 is in a separated position that avoids the movement path of the lid C. In this design, the support frame 511 consists of two support rods 5111. The lid C, located on the support frame 511, is placed within the cavity 5112 formed by the inner surfaces of the two support rods 5111. A platform 5113 is provided on the inner side of each support rod 5111, thus supporting the edge of the lid C within the cavity 5112. When it is necessary to control the expansion of the support frame 511 to cancel the supporting effect on the lid C, the corresponding drive mechanism drives the two support rods 5111 away from each other, causing the platform 5113 to move away from the area below the lid C. Conversely, after the support frame 5111 moves upward and resets, the two support rods 5111 close and reconnect, causing the size of the cavity 5112 to shrink back to a size suitable for the lid C.

[0066] The claw C1 is a pair of claws c1 consisting of two symmetrically arranged claw units c11, and the claw pair c1 is in the shape of an "eight". The lower end of the claw unit c11 is provided with a wedge-shaped check claw c12 that engages with the engagement hole B11. To prevent the claw C1 from deforming and flaring outward, which would prevent the claw C1 from being inserted into the guide groove B1 on the inner wall of the controller box B during assembly of the cover C and the controller box B, through holes 51111 are provided on the rods of the two support rods 5111. The through holes 51111 are located at the gap 51131 of the edge 5113 (the gap 51131 is provided to avoid positional interference between the top rod 514 and the claw unit c11 when the cover C is placed in the cavity 5112). The core of the through hole 51111 is located horizontally and is coaxial with the claw unit c11 on the claw pair c1. The hammer face, the two push rods 514 respectively pass through the two through holes 51111 and form a sliding fit with them. When the box cover C is placed on the platform edge 5113 in the cavity 5112, the hole area of ​​the through hole 51111 is arranged opposite to the middle and upper part of the claw unit c11. The third drive unit 513 located outside the support frame 511 drives the two push rods 5111 to move towards each other along the hole core direction of the through hole 51111 and push the two claw units c11 of the claw pair c1 respectively, or drive the two push rods 514 to move away from each other to the adjacent rod ends and separate from the two claw units c11 of the claw pair c1.

[0067] After the cover C is placed into the cavity 5112 formed by the support rods 5111, the third drive unit 513 located outside the support frame 511 drives the two opposing push rods 514 on the two support rods 5111 to move towards each other along the core direction of the through hole 51111. The two push rods 514 push the two claw units c11 in the claw pair c1 respectively, so that the free ends of the two claw units c11 move closer to each other and close to the area opposite to the opening area of ​​the controller box B. In this way, when the cover C is pressed down, the cover C will not be unable to be assembled with the controller box B due to the deformation of the claw units c11. After the third drive unit 513 drives the opposing push rods 514 to move in the opposite direction and reset, the inner rod end of the push rod 514 will not interfere with the claws C1 on the cover C when the cover C is subsequently inserted into the cavity 5112.

[0068] Furthermore, the pressing mechanism 512 includes a pressure plate 5121. The plate surface of the pressure plate 5121 and the cavity 5112 formed by the support rod 5111 are arranged vertically opposite each other. A telescopic cylinder 5122 is arranged above the pressure plate 5121. The piston rod of the telescopic cylinder 5122 is located in the plumb direction and its end is connected to the pressure plate 5121. The telescopic cylinder 5122 drives the pressure plate 5121 to move downward and press against the box cover C, moving it towards the controller box body B, or drives the pressure plate 5121 to move upward to the initial position spaced apart from the support frame 511. In this scheme, the pressing mechanism 512 specifically uses the pressure plate 5121 to press against the box cover C. By extending and retracting the telescopic cylinder 5122, the vertical displacement of the pressure plate 5121 is controlled, thereby realizing the pressure plate 5121 pressing against or moving upward to reset the box cover C.

[0069] In addition, the capping unit 500 also includes a third feeding and conveying unit 520, and a third gripping unit 530 gripping the box cap C located on the third feeding and conveying unit 520 and moving it into the cavity 5112 formed by the support rod 5111, or gripping the controller box body B containing the controller circuit board A and placing it in the positioning groove 730 on the tray 700 with the box opening facing upwards. In this solution, the third feeding and conveying unit 520 is used to convey the box cap C to be capped, and the third gripping unit 530 can grip the box cap C to be capped and place it into the cavity 5112 on the box cap clamping mechanism 510, or place the controller box body B containing the controller circuit board A after being processed by the insertion unit 400 upright in the positioning groove 730 on the tray 700 to perform the capping operation.

[0070] Combination Figure 20-25As shown, in a preferred embodiment, the test unit 600 includes a base 610. The base 610 has a limiting groove 611 for accommodating a controller S. The controller S, placed within the limiting groove 611, has a box-shaped terminal block D with its opening facing upwards. Pins D1 arranged in a matrix within the terminal block D extend from the bottom to the opening along the depth direction of the box cavity. A probe holder 620 is positioned above the terminal block D, opposite to its opening. A rod-shaped, retractable probe 621, corresponding one-to-one with each pin D1, is positioned on the lower surface of the probe holder 620. The probe 621 extends from the probe holder 620 into the box cavity of the terminal block D along the depth direction of the box cavity. A connector 622 is provided on the lower end face of the pin holder 620. A socket 6221 corresponding to the pin D1 is provided on the lower end face of the connector 6222. The diameter of the socket 6221 is larger than the diameter of the pin D1. The socket 6221 extends upward through the connector 622, and the probe 621 is arranged inside the socket 6221. The pin D1, the probe 621 and the core of the socket 6221 are parallel, and the tip 6211 of the probe 621 is arranged in close contact with the wall of the socket 6221. When the driving mechanism drives the probe holder 620 to descend, the connector 622 is inserted into the cavity of the terminal D when the tip 6211 of the probe 621 and the tip of the pin D1 press against each other.

[0071] In this scheme, when performing electrical connection tests on the assembled controller S, the conveyor belt 200 transports the tray 700 to the test unit 600. The controller S is placed in the limiting groove 611 on the base 610, with the box-shaped terminal block D on the controller S facing upwards. The probe holder 620 is driven downwards by the drive mechanism, causing the socket 622 to move downwards synchronously with the probe holder 620 and be inserted into the box cavity of the terminal block D. The pin D1 in the terminal block D enters the corresponding socket 6221 on the socket 622, thereby causing the pin D1 to abut against the probe tip 6211 of the probe 621 in the socket 6221, thus performing an electrical connection test on the controller S to test whether the controller S can be used normally.

[0072] The probe 621 and pin D1 are constrained by the cavity of the socket 6221, ensuring that the probe 621 itself will not be skewed. At the same time, since the tip 6211 of the probe 621 is arranged in close contact with the wall of the socket 6221, as long as the pin D1 of the terminal D enters the socket 6221, the tip of the pin D1 and the tip 6211 of the probe 621 will not be misaligned. The two can effectively make contact within the socket, ensuring that the test can proceed smoothly.

[0073] It should be noted that the telescopic structure of probe 621 is a conventional design in the prior art, and there are corresponding standard parts available. Therefore, the telescopic structure of probe 621 will not be described in detail in this application. Additionally, in this application, the diameter of the socket 6221 is larger than the diameter of pin D1. Figure 24 As shown, pin D1 and socket 6221 do not need to form a tight mating fit. This is so that pin D1, which may be slightly misaligned but does not affect normal use, can be inserted into socket 6221.

[0074] Furthermore, the insertion gap between the connector 622 and the terminal D is relatively large, and the pin D1 and the socket 6221 are not tightly inserted. Therefore, when the drive mechanism drives the probe seat 620 to move upward, it is not necessary to fix the controller S in the limiting groove 611, and the connector 622 can be moved out of the terminal D without moving the controller S upward synchronously. Of course, a pneumatic clamp can also be set on the base 610 to limit the upward displacement of the controller S and ensure the stability of the controller S's posture.

[0075] Furthermore, when the tray 700 carrying the controller S moves from the pressure cap unit 500 to the testing unit 600, the fourth gripping unit 630 grips the controller S to be tested placed on the tray 700 and transfers it into the limiting groove 611, or grips the controller S that has completed testing in the limiting groove 611 and transfers it into either the defective product placement area 640A or the qualified product placement area 640B. During testing, the fourth gripping unit 630 grips the controller S to be tested placed on the tray 700 and transfers it into the limiting groove 611 for testing. For the controller S that has completed testing, the fourth gripping unit 630 can remove it from the limiting groove 611. Defective controllers are transferred to the defective product placement area 640A by the fourth gripping unit 630, while undefective controllers are transferred to the qualified product placement area 640B, thus achieving classified storage for convenient subsequent processing.

[0076] like Figure 3 As shown, the conveyor belt 200 includes an upper conveyor belt 210 located on the workbench 100. A lower conveyor belt 220 is arranged below the workbench 100, vertically opposite to and parallel to the upper conveyor belt 210. The upper conveyor belt 210 and the lower conveyor belt 220 have opposite conveying directions, and a shifting mechanism 230 is provided at their ends. The shifting mechanism 230 includes a vertically positioned guide rail 231, on which a support platform 232 is provided to provide guidance and limiting. The horizontal support platform 232 has a section parallel to the conveying directions of the upper and lower conveyor belts 210 and 220. The indexing conveyor belt 2321 is driven by a drive mechanism to raise the support platform 232 along the guide rail 231 to a high position where the surface of the indexing conveyor belt 2321 is flush with the surface of the upper conveyor belt 210, or to a low position where the surface of the indexing conveyor belt 2321 is flush with the surface of the lower conveyor belt 220. When the support platform 232 is at a high position, the conveying direction of the indexing conveyor belt 2321 on the support platform 232 is the same as the conveying direction of the upper conveyor belt 210. When the support platform 232 is at a low position, the conveying direction of the indexing conveyor belt 2321 on the support platform 232 is the same as the conveying direction of the lower conveyor belt 220.

[0077] The upper conveyor belt 210 on the workbench 100 is used to transport the controller circuit board A and the controller box B or box cover C sequentially to various workstations for programming, insertion, capping, and testing. After all operations are completed, the products on the tray 700 are removed, and the empty tray 700 can be transported to the high-positioned support platform 232 on the indexing mechanism 230 at the end of the upper conveyor belt 210. Subsequently, the drive mechanism drives the support platform 232 to move down to a low position along the guide rail 231, and the indexing conveyor belt 2321 on the support platform 232 transports the empty tray 700 on it to the lower conveyor belt 220. Thus, the lower conveyor belt 220 transports the empty pallet 700 to the low-position support platform 232 of the indexing mechanism 230 located at the upstream end of the upper conveyor belt 210. The support platform 232 is then driven by the drive mechanism to rise to the high position, so as to transport the empty pallet 700 on it back to the upper conveyor belt 210, thereby forming a circular movement path for the pallet 700. The pallet 700 can be reused without the need to continuously add pallets 700 to the upper conveyor belt 210.

[0078] Furthermore, considering that the entire system still requires manual feeding or removal of the final product, and that the system requires manual provision of the controller circuit board A, controller housing B, or housing cover C, the programming unit 300, insertion unit 400, capping unit 500, and testing unit 600 are arranged on the same side of the conveyor belt 200, while the manual operation position is arranged on the other side of the conveyor belt 200. This avoids the safety hazards that could arise from the manual and mechanical operation positions coexisting on the same side.
