Description

Technical Field

[0001] The invention patent relates to radar controller assembly, and specifically to a controller assembly system. Background Art

[0002] Vehicle-mounted radar usually consists of sensors, controllers and wiring harnesses, where the sensors are installed on the front or rear bumper of the vehicle, and the controllers are installed on the vehicle body. The sensors emit and receive ultrasonic waves, while the controllers receive the signals from the sensors and perform calculations, allowing the driver to understand the conditions in front of and behind the vehicle and avoid collisions between the vehicle and obstacles.

[0003] The technical solution disclosed in the patent document named "Vehicle Controller" (document number CN218352873U) includes a housing, a side cover and a circuit board; the housing and the side cover are detachably mounted together, and the circuit board is located inside the housing; a second card slot is provided on two opposite inner side walls of the housing, and the end of the circuit board is located in the matching slot of the second card slot, and the slot width of the second card slot is slightly larger than the thickness of the circuit board. The vehicle controller is provided with a second card slot on the inner side of the housing, and the circuit board is assembled in the housing through the second card slot.

[0004] The technical solution disclosed in the patent document entitled "Host Controller of Radar Probe" (document number CN212723312U) includes a shell having a accommodating cavity and an opening at one end, a circuit board assembled in the accommodating cavity of the shell, and an electrical connector with one end inserted into the accommodating cavity from the opening of the shell and connected to the circuit board.

[0005] like Figure 1 As shown in Figure 2, the controller S is mainly composed of a controller box body B, a controller circuit board A and a box cover C. During the production process, the controller circuit board A must first be programmed. After programming, the controller circuit board A is placed into the controller box body B through the box opening of the controller box body B and the box cover C is placed on the box opening. Finally, the wiring terminal D on the controller S connected to the controller circuit board A is electrically connected to test whether the controller S can be used normally. In the prior art, for the assembly of the controller, each process is usually set independently, and the assembly of some processes is still done manually. The loading, unloading, assembly and even transportation of each process and each other require a large amount of manpower costs. At the same time, the production efficiency will also be affected by the efficiency of manual operation, which is not conducive to improving the assembly efficiency of the controller. At present, there is still a lack of a complete assembly line for the assembly of radar controllers to solve the above problems. Summary of the invention

[0006] The present invention provides a controller assembly system, which can automatically assemble a controller circuit board, a controller box body, and a box cover, thereby improving the controller assembly efficiency, and simultaneously performing an electrical connection test on the assembled controller.

[0007] In order to achieve the above purpose, the technical solution adopted is: a controller assembly system, a flat conveyor belt is set on the workbench, and the burning unit, the insertion unit, the capping unit and the testing unit are arranged on the workbench from the upstream to the downstream of the conveyor belt. A tray for carrying the controller circuit board and the controller box body is set on the conveyor belt, wherein:

[0008] A burning unit, used for burning the program to the controller circuit board;

[0009] A plug-in unit, used to place the controller circuit board into the controller box;

[0010] A cover pressing unit, used for placing a cover on the box opening of a controller box body having a controller circuit board inside;

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

[0012] Compared with the prior art, the technical effect of the present invention is as follows: the burning unit, the insertion unit, the capping unit and the testing unit are arranged on the workbench in sequence from the upstream to the downstream of the conveyor belt. The controller circuit board, the controller box body and the box cover constituting the controller can be conveyed by the conveyor belt to the corresponding units in sequence for burning, insertion, capping and testing. The system can complete a complete set of assembly and testing operations of the controller, and the steps requiring manual operation are greatly reduced. At the same time, the various processes are closely connected with each other and have an orderly sequence, making product transportation more convenient, which helps to improve the assembly efficiency of the controller.

[0039] The following is combined with Figure 1-24 And related contents, the present invention is further described in detail:

[0040] A controller assembly system is provided. A flat conveyor belt 200 is arranged on a workbench 100. A burning unit 300, an insertion unit 400, a capping unit 500 and a testing unit 600 are arranged on the workbench 100 in sequence from upstream to downstream of the conveyor belt 200. A tray 700 for carrying a controller circuit board A and a controller box body B is provided on the conveyor belt 200, wherein: the burning unit 300 is used to program the controller circuit board A; the insertion unit 400 is used to place the controller circuit board A into the controller box body B; the capping unit 500 is used to place a box cover C on the box cover of the controller box body B with the controller circuit board A inside; and the testing unit 600 is used to perform an electrical connection test on a terminal D on a controller S. The controller S is composed of the controller circuit board A, the controller box body B and the box cover C.

[0041] In the above scheme, the burning unit 300, the insertion unit 400, the capping unit 500 and the testing unit 600 are arranged on the workbench 100 in sequence from the upstream to the downstream of the conveyor belt 200. The controller circuit board A, the controller box body B and the box cover C constituting the controller S are sequentially conveyed 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 of the controller S. The various workstations are closely connected with each other and arranged in order, so that the product transportation is more convenient and the assembly efficiency of the controller S is improved.

[0042] It should be noted that the purpose of the tray 700 is to support the controller circuit board A and the controller box body B to move to the corresponding workstation for assembly, and the box cover C does not need to be supported by the tray 700 to enter the position of the cover pressing unit 600. This is because the assembly operation between the controller box body B and the box cover C is the last step before the test. Before the cover pressing, the tray 700 does not need to support the box cover C, and a separate loading structure for the box cover C can be set at the cover pressing unit 600. Of course, the controller circuit board A, the controller box body B and the box cover C can also be directly placed on the tray 700 upstream of the burning unit 300.

[0043] Combination Figure 5-8As shown, as a preferred embodiment, the burning unit 300 includes a carrier 310, on which a placement area for carrying the controller circuit board A is provided, and a burning probe 320 for abutting against the burning contacts at the bottom of the controller circuit board A is provided on the placement area, and a clamping unit 330 is provided above the placement area of ​​the controller circuit board A. The first driving unit 340 drives the clamping unit 330 to move downward to a limiting position where the clamping unit 330 presses against the upper surface of the control circuit board A or drives the clamping unit 330 to move upward and move to an avoidance position where the clamping unit 330 and the upper area of ​​the board surface of the controller circuit board A are staggered.

[0044] In this solution, during the process of programming the controller circuit board A, the controller circuit board A is placed in the placement area on the stage 310 (the programming probe 320 disposed in the placement area will abut against the programming contact on the lower board surface of the controller circuit board A to program the controller circuit board A), and the first driving unit 340 can drive the pressing unit 330 to move downward, so that the pressing unit 330 presses the controller circuit board A on the stage 310 to ensure the stability of the controller circuit board A during the programming process. Conversely, the first driving unit 340 can drive the pressing unit 330 to move upward to cancel the pressing effect on the controller circuit board A, so as to remove the controller circuit board A after programming from the stage 310.

[0045] In addition, the first driving unit 340 can also drive the pressing unit 330 to rotate to an avoidance position that is arranged offset from the area above the surface of the controller circuit board A on the carrier 310, so that the area above the surface of the controller circuit board A is not blocked, thereby facilitating the placement of the controller circuit board A on the carrier 310. Since the pressing unit 330 is offset from the area above the surface of the controller circuit board A on the carrier 310, this setting facilitates the arrangement of the manipulator to load or unload materials in the controller circuit board A placement area on the carrier 310, and the pressing unit 330 will not interfere with the movement of the manipulator, which helps to simplify the movement path of the manipulator and improve the overall operation efficiency of the equipment.

[0046] In detail, in the prior art, the controller circuit board A needs to be placed flat on the carrier 310 during the burning process, and the controller circuit board A is generally small and thin. The robot usually grabs the controller circuit board A by adsorbing the upper surface of the controller circuit board A with a suction cup. Therefore, if the clamping unit 330 is always maintained in the area above the surface of the controller circuit board A on the carrier 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, a stand 350 is provided at the lower end of the carrier 310, and a first telescopic cylinder 341 is provided on the stand 350. The rod core of the piston rod of the first telescopic cylinder 341 is located in the plumb direction and the rod end is connected to a mounting plate 342. A rotating cylinder 343 is provided on the mounting plate 342. The axis core of the rotating axis of the rotating cylinder 343 is located in the plumb direction and the axis end is connected to the clamping unit 330. In this solution, the first telescopic cylinder 341 can drive the mounting plate 342 to move up and down together with the rotating cylinder 343 thereon, so that the clamping unit 330 connected to the axial end of the rotating cylinder 343 can move up and down to press the controller circuit board A placed on the carrier 310; and the rotating cylinder 343 can drive the clamping unit 330 to rotate with the rotating axis of the rotating cylinder 343 as the rotating axis core, so that the clamping unit 330 can be transferred to an avoidance position that is staggered with the area above the board surface of the controller circuit board A, so that the robot arm can grab the burned controller circuit board A from the carrier 310 or grab the controller circuit board A to be burned and place it on the carrier 310.

[0048] The end of the rotating shaft of the rotating cylinder 343 is connected to a connecting arm 344 that is cantilevered in the radial direction, and the pressing unit 330 is connected to the cantilevered end of the connecting arm 344. The connecting arm 344 serves as a transitional connection between the pressing unit 330 and the rotating cylinder 343, ensuring that the cylinder body of the rotating cylinder 343 and the controller circuit board A are reasonably avoided, while enabling the pressing unit 330 to press the controller circuit board A.

[0049] In addition, it should be supplemented that: the burning unit 300 also includes a first loading and conveying unit 360, and the first grabbing unit 370 grabs the controller circuit board A to be burned on the first loading and conveying unit 360 and moves it to the placement area on the carrier 310, or grabs the controller circuit board A that has been burned on the placement area and moves it to the tray 700 on the conveyor belt 200. The first loading and conveying unit 360 can convey the controller circuit board A to be burned, and the first grabbing unit 370 can be used to realize the loading or unloading of the carrier 310.

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

[0051] In this solution, the controller circuit board A burned by the burning unit 300 is specifically placed in the guide groove 710 on the tray 700, and the controller box body B is placed in the accommodating groove 720 on the tray 700, and the box openings of the controller circuit board A and the controller box body B are arranged opposite to each other in the groove length direction of the guide groove 710. The pushing unit 410 is used to push the controller circuit board A placed on the guide groove 710 to move along the groove length direction of the guide groove 710 into the controller box body B, thereby quickly completing the insertion operation between the controller circuit board A and the controller box body B. After the assembly is completed, the pushing 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 is displaced along the groove length direction of the guide groove 710 under the guiding limit of the guide groove 710.

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

[0054] The second driving unit 412 can be a telescopic cylinder, the rod core direction of its piston rod is parallel to the groove length direction of the guide groove 710 and the rod end is connected to the push plate 411. The push plate 411 can be displaced along the groove length direction of the guide groove 710 by the extension and contraction of the telescopic cylinder to push the controller circuit board A placed in the guide groove 710 to move.

[0055] The surface of the push plate 411 is perpendicular to the groove length direction of the guide groove 710, so that when the push plate 411 pushes the controller circuit board A, the force points of the controller circuit board A are evenly distributed, ensuring that the controller circuit board A slides stably in the guide groove 710 without being skewed. In addition, the moving path of the push plate 411 is within the groove cavity range of the guide groove 710, and this setting is also to ensure that when the push plate 411 pushes the controller circuit board A, the plate body of the push plate 411 can move in the groove cavity of the guide groove 710 without interfering with the groove wall or groove bottom of the guide groove 710.

[0056] The upper plate surface of the tray 700 is connected with a guide seat 710A, and the guide groove 710 is provided on the upper end surface of the guide seat 710A, and the notch of the guide groove 710 faces upward, and the groove length direction is in the horizontal direction, and the two ends of the guide groove 710 in the groove length direction pass through the opposite side seat surface of the guide seat 710A. This scheme further limits the arrangement of the guide groove 710, and the guide groove 710 is arranged on the guide seat 710A on the tray 700 instead of directly on the plate body of the tray 700, and the structural design is more reasonable.

[0057] In addition, the insertion unit 400 further includes a second loading and conveying unit 420. When the conveyor belt 200 conveys the tray 700 to the insertion unit 400, the second grabbing unit 430 grabs the controller box body B on the second loading and conveying unit 420 and moves it into the receiving groove 720 or grabs the burned controller circuit board A and moves it into the guide groove 710. The second loading and conveying unit 420 is used to convey the controller box body B to be assembled, and the second grabbing unit 430 is used to grab the controller box body B and move it into the receiving groove 720 so as to be inserted with the burned controller circuit board A located in the guide groove 710.

[0058] Combination Figure 11-18 As shown, as a preferred solution, the cover pressing unit 500 includes a cover clamping mechanism 510, and a positioning groove 730 for accommodating a controller box body B is provided on a flat tray 700, and a controller circuit board A is provided inside the controller box body B. The controller box body B is a flat square box body with a box opening on one side and a circuit board inside. The box opening of the controller box body B placed in the vertical positioning groove 730 is arranged upward;

[0059] When the conveyor belt 200 transports the tray 700 to the position of the cover pressing unit 500, the box cover clamping mechanism 510 is located above the tray 700, and the box cover clamping mechanism 510 clamps the flat box cover C, and the box cover C and the box opening of the controller box body B in the positioning groove 730 are arranged opposite to each other up and down; the edge of the lower end surface of the box cover C is connected to a claw C1 extending into the box cavity of the controller box body B, and the driving mechanism drives the box cover clamping mechanism 510 to move downward along the depth direction of the box cavity of the controller box body B to the end position where the claw C1 and the clamping hole B11 on the controller box body B are mutually clamped, or the clamping effect on the box cover C is released and the box cover clamping mechanism 510 is driven to move upward and reset to the initial position.

[0060] In this solution, when assembling the controller box body B and the box cover C, after the controller circuit board A and the controller box body B are inserted by the insertion unit 500, the controller box body B is placed in the positioning groove 730 on the tray 700 with the box opening facing upward to position the controller box body B. The box cover C clamped by the box cover clamping mechanism 510 is in a flat state, and then the driving mechanism drives the box cover clamping mechanism 510 to move toward the box opening of the controller box body B placed on the tray 700 along the box cavity depth direction of the controller box body B until the claw C1 on the box cover C and the clamping hole B11 on the controller box body B are mutually engaged, that is, the automatic assembly operation between the box cover C and the controller box body B is realized.

[0061] After the claw C1 on the box cover C and the engaging hole B11 on the controller box body B are engaged with each other, the driving mechanism releases the clamping effect of the box cover clamping mechanism 510 on the box cover C and drives the box cover clamping mechanism 510 to move upward and reset to the initial position, so as to repeat the above assembly operation for the subsequent controller box body B and box cover C.

[0062] Furthermore, the box cover clamping mechanism 510 includes a support frame 511 with a flat frame surface. When the support frame 511 is in the initial position, the support frame 511 supports the cover edge of the box cover C and the claw C1 and the support frame 511 are in a position of avoiding each other. When the pressing mechanism 512 above the support frame 511 moves downward and presses the upper cover surface of the box cover C on the support frame 511, the pressing mechanism 512 and the support frame 511 move downward synchronously along the box cavity depth direction of the controller box body B until the claw C1 is inserted into the controller. The stop position of the guide groove B1 vertically arranged on the inner box wall of the box body B; 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 and moves down to the end position where the claw C1 and the clamping hole B11 at the lower end of the guide groove B1 are engaged with each other; after the claw C1 and the clamping 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 retracts to the initial size of the cover edge of the support box cover C.

[0063] In this solution, in the initial state, the box cover C is placed on the supporting frame 511, and the supporting frame 511 is used to support the cover edge of the box cover C, and the claw C1 is in the frame area of ​​the supporting frame 511. Subsequently, the pressing mechanism 512 above the supporting frame 511 moves downward and presses the upper cover surface of the box cover C on the supporting frame 511, and the pressing mechanism 512 cooperates with the supporting frame 511 to clamp the box cover C. When the pressing mechanism 512 and the supporting frame 511 move downward synchronously along the depth direction of the box cavity of the controller box body B, the box cover C will be carried and displaced toward the box opening of the controller box body B until the claw C1 on the box cover C is inserted into the guide groove B1 arranged vertically on the inner box wall of the controller box body B. At this time, the frame area of ​​the support frame 511 expands, thereby separating from the box cover C (because the claw C1 has been inserted into the guide groove B1 on the inner wall of the controller box body B. Under the constraint of the claw C1 by the guide groove B1, even without the support of the support frame 511, the box cover C can maintain a flat posture and move along the groove length direction of the guide groove B1 without tilting), avoiding the interference of the support frame 511 on the closing of the box cover C and the box opening of the controller box body B. After the support frame 511 is separated from the box cover C, the holding mechanism 512 continues to move downward, thereby pushing the box cover C to close on the box opening of the controller box body B, and the claw C1 will also interlock with the clamping hole B11 at the lower end of the guide groove B1 to achieve the assembly operation between the box cover C and the controller box body B.

[0064] After the above operation is completed, the support frame 511 and the pressing mechanism 512 move upward and reset, and the frame area of ​​the support frame 511 shrinks to the initial size of supporting the cover edge of the box cover C. The size of the frame area of ​​the support frame 511 determines whether the support frame 511 can support the box cover C. When the frame area of ​​the support frame 511 is in a tightened state, the support frame 511 is placed at the outer peripheral position of the box cover C and supports the cover edge of the box cover C to prevent the box cover C from falling downward; when the frame area of ​​the support frame 511 is in an expanded state, the frame body of the support frame 511 cannot be maintained under the cover edge of the box cover C, and there will be no interference between the box cover 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 to continue to push the box cover C to move downward to cover the box opening of the controller box body B.

[0065] Furthermore, the support frame 511 is a square frame structure composed of two U-shaped support rods 5111 with openings arranged opposite to each other. The rod bodies of the two support rods 5111 are located in a horizontal plane and the rod ends are butted against each other. The area enclosed by the inner rod surfaces of the two support rods 5111 constitutes a cavity 5112 for accommodating the box cover C. The opposite side rod surfaces between the two support rods 5111 are provided with a platform edge 5113 protruding toward the middle of the cavity 5112, and the platform edge 5113 is arranged along the cover edge of the box cover C. The cover edge of the box cover C located in the cavity 5112 is placed on the upper end surface of the platform edge 5113. When the support frame 511 is in the stop position, the driving mechanism drives the two support rods 5111 to move away from each other and the platform edge 5113 is in a separation position to avoid each other from the moving path of the box cover C. In this solution, the support frame 511 is composed of two support rods 5111, and the box cover C located on the support frame 511 is placed in the cavity 5112 formed by the inner rod surfaces of the two support rods 5111. The inner side of the support rods 5111 is provided with a platform edge 5113, so that the cover edge of the box cover C located in the cavity 5112 is supported by the platform edge 5113. When it is necessary to control the expansion of the frame domain of the support frame 511 to cancel the supporting effect on the box cover C, the two support rods 5111 are driven away from each other by the corresponding driving mechanism, so that the platform edge 5113 is moved away from the lower area of ​​the box cover C. On the contrary, after the support frame 511 is moved up and reset, the two support rods 5111 are closed and docked again to shrink the size of the cavity 5112 to a size that matches the size of the box cover C.

[0066] The claw C1 is a claw pair c1 composed of two symmetrically arranged claw units c11, and the claw pair c1 is in an "eight" shape as a whole. The lower end of the claw unit c11 is provided with a wedge-shaped non-return claw c12 that is engaged with the engaging hole B11. In order to prevent the claw C1 from deforming and tilting outward, which may cause the claw C1 to be unable to be inserted into the guide groove B1 on the inner wall of the controller box body B when the box cover C and the controller box body B are assembled, through holes 51111 are provided on the rod bodies of the two supporting rods 5111. The through holes 51111 are arranged at the spacing missing part 51131 of the table edge 5113 (the setting of the spacing missing part 51131 avoids the position interference between the push rod 514 and the claw unit c11 when the box cover C is placed in the cavity 5112). The hole core of the through hole 51111 is located in the horizontal direction and is coaxial with the claw unit c11 on the claw pair c1. Hammer surface, the two push rods 514 are respectively inserted through the two through holes 51111 and form a sliding fit therewith, when the box cover C is placed on the table edge 5113 in the cavity 5112, the hole area of ​​the through hole 51111 is arranged relatively to the middle and upper part of the claw unit c11, and the third driving unit 513 located on the outside of the support frame 511 drives the two opposite push rods 514 on the two support rods 5111 to move toward each other along the hole core direction of the through hole 51111 and respectively push the two claw units c11 of the claw pair c1 or drive the two push rods 514 to move back to the adjacent rod ends and separate from the two claw units c11 of the claw pair c1.

[0067] After the box cover C is placed into the cavity 5112 formed by the support rods 5111, the third driving unit 513 located outside the support frame 511 drives the two push rods 514 arranged opposite to each other on the two support rods 5111 to move toward each other along the core direction of the through hole 51111, and 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 are close to each other and gathered to the range opposite to the box opening area of ​​the controller box body B, so that when the box cover C is pressed down, the box cover C will not be unable to be assembled with the controller box body B due to the deformation of the claw units c11. After the third driving unit 513 drives the two opposite push rods 514 to move in the opposite direction and reset, when the box cover C is subsequently inserted into the cavity 5112, the inner rod ends of the push rods 514 will not interfere with the claws C1 on the box cover C.

[0068] Furthermore, the pressing mechanism 512 includes a pressing plate 5121, the plate surface of the pressing plate 5121 and the cavity 5112 surrounded by the supporting rod 5111 are arranged opposite to each other up and down, a telescopic cylinder 5122 is arranged above the pressing plate 5121, the rod core of the piston rod of the telescopic cylinder 5122 is located in the plumb direction and the rod end is connected to the pressing plate 5121, and the telescopic cylinder 5122 drives the pressing plate 5121 to move downward and press the box cover C to move toward the controller box body B or drives the pressing plate 5121 to move upward to the initial position spaced apart from the supporting frame 511. In this solution, the pressing mechanism 512 specifically uses the pressing plate 5121 to press the box cover C, and controls the upward and downward displacement of the pressing plate 5121 by the telescopic cylinder 5122, so as to achieve the pressing of the box cover C by the pressing plate 5121 or the upward resetting.

[0069] In addition, the capping unit 500 further includes a third loading and conveying unit 520, and a third grabbing unit 530 grabs the box cover C on the third loading and conveying unit 520 and moves it into the cavity 5112 surrounded by the support rod 5111, or grabs the controller box body B with the controller circuit board A inside and places it in the positioning groove 730 on the tray 700 with the box opening facing upward. In this solution, the third loading and conveying unit 520 is used to convey the box cover C to be pressed, and the third grabbing unit 530 can grab the box cover C to be pressed and place it in the cavity 5112 on the box cover clamping mechanism 510, or stand the controller box body B with the controller circuit board A inside processed by the insertion unit 400 in the positioning groove 730 on the tray 700, so as to implement the capping operation.

[0070] Combination Figure 20-25As shown, as a preferred embodiment, the test unit 600 includes a base 610, and a limiting groove 611 for accommodating a controller S is provided on the base 610. The controller S placed in the limiting groove 611 has a box-shaped terminal D with the box opening facing upward. The pins D1 arranged in a matrix in the terminal D extend from the bottom of the box to the box opening along the depth direction of the box cavity. A probe seat 620 is provided above the terminal D and is opposite to the box opening. A rod-shaped and retractable probe 621 corresponding to the pin D1 is provided on the lower end surface of the probe seat 620. The probe 621 extends from the probe seat 620 to the box cavity of the terminal D along the depth direction of the box cavity of the terminal D. The probe A socket 622 is provided on the lower end surface of the needle holder 620, and a socket 6221 corresponding to the pin D1 is provided on the lower end surface of the socket 622, and the hole 6221 has a larger diameter than the diameter of the pin D1. The hole 6221 passes through the socket 622 upward and the probe 621 is arranged in the socket 6221. The pin D1, the probe 621 and the hole core direction of the socket 6221 are parallel, and the needle head 6211 of the probe 621 is arranged in contact with the hole wall of the socket 6221. The driving mechanism drives the probe holder 620 to descend until the needle head 6211 of the probe 621 and the needle tip of the pin D1 are pressed against each other, and the socket 622 is inserted into the box cavity of the terminal D.

[0071] In this solution, when the assembled controller S is subjected to an electrical connection test, the conveyor belt 200 conveys the tray 700 to the position of the test unit 600. The controller S is placed in the limit groove 611 on the base 610, and the box opening of the box-shaped terminal D on the controller S is arranged upward. The driving mechanism drives the probe seat 620 to move downward, so that the socket 622 moves downward synchronously with the probe seat 620 and is plugged into the box cavity of the terminal D. The pin D1 in the terminal D enters the corresponding socket 6221 on the socket 622, so that the pin D1 abuts against the needle 6211 of the probe 621 in the socket 6221, and the controller S is powered on to test whether the controller S can be used normally.

[0072] Among them, the hole cavity of the socket 6221 is used to constrain the probe 621 and the pin D1, which ensures that the probe 621 itself will not be skewed. At the same time, since the needle head 6211 of the probe 621 is arranged in close contact with the hole wall of the socket 6221, as long as the pin D1 of the terminal D enters the socket 6221, the needle tip of the pin D1 and the needle head 6211 of the probe 621 will not be misaligned with each other, and the two can effectively achieve abutment in the socket to ensure smooth testing.

[0073] It should be noted that the telescopic structure of the probe 621 is a conventional setting in the prior art and has corresponding standard parts, so the telescopic structure of the probe 621 is not elaborated in detail in this application. In addition, in this application, the diameter of the jack 6221 is larger than the diameter of the pin D1. Fig.24 As shown, the pin D1 and the socket 6221 do not need to form a tight plug-in fit, which is also to ensure that the pin D1 can be inserted into the socket 6221 even if it is slightly skewed but does not affect normal use.

[0074] In addition, the plug-in clearance between the socket 622 and the terminal D is relatively large, and the pin D1 and the socket 6221 are not tightly plugged, so when the driving mechanism drives the probe seat 620 to move upward, there is no need to fix the controller S in the limit groove 611, and the socket 622 can be moved out of the terminal D without synchronously moving the controller S upward. Of course, a pneumatic clamp can also be set on the base 610 to limit the upward displacement of the controller S to ensure the stability of the controller S.

[0075] Furthermore, when the tray 700 carrying the controller S moves from the cover unit 500 to the test unit 600, the fourth grabbing unit 630 grabs the controller S to be tested on the tray 700 and transfers it to the limiting groove 611, or grabs the controller S that has been tested in the limiting groove 611 and transfers it to one of the defective product placement area 640A and the qualified product placement area 640B. During the test, the fourth grabbing unit 630 grabs the controller S to be tested on the tray 700 and transfers it to the limiting groove 611 for testing. The controller S that has been tested can be taken out of the limiting groove 611 by the fourth grabbing unit 630, and the defective controller S is transferred to the defective product placement area 640A by the fourth grabbing unit 630, and the non-defective controller S is transferred to the qualified product placement area 640B, so as to achieve classified storage and facilitate subsequent processing.

[0076] like Figure 3 As shown, the conveyor belt 200 includes an upper conveyor belt 210 located on the surface of the workbench 100, and a lower conveyor belt 220 is arranged under the surface of the workbench 100, which is opposite to and parallel to the upper conveyor belt 210. The conveying directions of the upper conveyor belt 210 and the lower conveyor belt 220 are opposite, and a transfer mechanism 230 is arranged at the end position. The transfer mechanism 230 includes a vertical guide rail 231, and a support platform 232 is arranged on the guide rail 231 to form a guide limit cooperation with the guide rail 231. The surface of the flat support platform 232 is provided with a support parallel to the conveying direction of the upper and lower conveyor belts 210 and 220. The driving mechanism drives the support platform 232 to rise along the guide rail 231 to a high position where the belt surface of the transfer conveyor belt 2321 is flush with the belt surface of the upper conveyor belt 210, or to descend to a low position where the belt surface of the transfer conveyor belt 2321 is flush with the belt surface of the lower conveyor belt 220; when the support platform 232 is at a high position, the conveying direction of the transfer conveyor belt 2321 on the support platform 232 is consistent with the conveying direction of the upper conveyor belt 210; when the support platform 232 is at a low position, the conveying direction of the transfer conveyor belt 2321 on the support platform 232 is consistent with the conveying direction of the lower conveyor belt 220.

[0077] The upper conveyor belt 210 provided on the table of the workbench 100 is used to convey the controller circuit board A, the controller box body B or the box cover C to each workstation in turn for burning, plugging, capping and testing. After all operations are completed, the products on the tray 700 are removed, and the empty tray 700 can be conveyed to the support platform 232 at a high position on the transfer mechanism 230 at the end of the upper conveyor belt 210. Then the driving mechanism drives the support platform 232 to move down to a low position along the guide rail 231, and the transfer conveyor belt 2321 on the support platform 232 conveys the empty tray 700 on it to the lower conveyor belt 220. Thus, the lower conveyor belt 220 transports the empty pallets 700 to the low-position support platform 232 of the transfer mechanism 230 arranged at the upstream end of the upper conveyor belt 210, and the support platform 232 is then driven by the driving mechanism to rise to a high position to transport the empty pallets 700 thereon back to the upper conveyor belt 210, thereby forming a circulating moving path for the pallets 700, and the pallets 700 can be recycled 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 taking away of the final product, the system requires manual feeding of the controller circuit board A, the controller box body B or the box cover C, the burning unit 300, the insertion unit 400, the capping unit 500 and the testing unit 600 are arranged on the same side of the conveyor belt 200, and the manual operation position is arranged on the other side of the conveyor belt 200. This can avoid the situation where the manual operation position and the mechanical operation position coexist on the same side, which may cause safety hazards.
