Description

Technical Field

[0001] This utility model relates to the field of intelligent electronic control equipment manufacturing technology, and more specifically, to an electronic control module assembly and testing line. Background Technology

[0002] The CAN module is an intelligent electronic control device that enables communication data forwarding between various electronic control units in a vehicle, thereby realizing a regional network control system for the vehicle's onboard electronic control devices. The CAN module's housing mainly consists of an interlocking bottom shell and a top shell, with a PCBA installed inside. During production, after assembling the bottom shell, top shell, and PCBA, the assembled product needs to undergo corresponding functional tests to ensure the quality and reliability of the final product.

[0003] Currently, the assembly and testing of modular products require the use of jigs. These jigs are transported via conveyor belts. After assembly and testing are completed, the jigs are unloaded and collected at the end of the conveyor belt. Then, the jigs are manually transferred back to the beginning of the conveyor belt and reloaded. This method is time-consuming and inefficient. Furthermore, since different jigs are required for assembly and testing, the loading and unloading of jigs becomes more complicated, requiring more manpower and resources, and significantly increasing the operating costs of the equipment. Utility Model Content

[0004] In view of this, the present invention provides an electronic control module assembly and testing line that can solve the above problems.

[0005] An electronic control module assembly and testing line includes a machine base and, on the machine base: a circulating conveying unit, including a fixture conveying mechanism and a circulating lifting mechanism, wherein the circulating lifting mechanism is located on both sides of the fixture conveying mechanism; the fixture conveying mechanism includes a first fixture conveying device and a second fixture conveying device arranged in parallel vertically, the first fixture conveying device and the second fixture conveying device having opposite conveying directions; a plurality of lifting drive components are spaced apart on the first fixture conveying device; clamping drive components are located on both sides of each lifting drive component; and a fixture clamping block is connected to the output end of each clamping drive component; and a loading assembly unit, including a bottom shell loading mechanism, a PCBA loading mechanism and a top shell loading mechanism arranged sequentially along the conveying direction of the first fixture conveying device. Each side is equipped with a tray conveying mechanism; a pressing unit, located on the side of the loading assembly unit away from the circulating conveying unit, includes a first conveying mechanism, a pressing worktable, and a pressing mechanism. The first conveying mechanism is used to transport the products in the assembly fixture to the pressing worktable; a functional testing unit includes a conveying robot and multiple sets of testing mechanisms, each set of testing mechanisms including multiple testing devices; a detection unit includes a rotary conveyor and a detection component, the detection component including multiple detection cameras, and multiple detection fixtures on the rotary conveyor, the rotary conveyor used to circulate the detection fixtures through the detection component; a unloading unit, located on one side of the detection unit, includes an unloading robot and a receiving mechanism, the unloading robot being used to transport the products in the detection fixture to the receiving mechanism.

[0006] In the above technical solution, this automated assembly and testing line is used to assemble and test electronic control modules. The electronic control module mainly consists of a bottom shell, a PCBA, and a top shell. The top shell covers the bottom shell, and the PCBA is located within the cavity formed after the bottom shell and top shell are closed. When this production line is in operation, a dedicated assembly fixture for the module product is placed on a fixture conveying mechanism. Driven by the fixture conveying mechanism, the assembly fixture sequentially passes through the loading assembly unit and the pressing unit. The bottom shell, PCBA, and top shell are all placed in their respective material trays and conveyed by the material tray conveying mechanism to the bottom shell loading mechanism, PCBA loading mechanism, and top shell loading mechanism, respectively. When the assembly fixture reaches the loading assembly unit, it sequentially passes through the bottom shell loading mechanism, PCBA loading mechanism, and top shell loading mechanism. The bottom shell loading mechanism, PCBA loading mechanism, and top shell loading mechanism respectively process the bottom shell, PCBA, and top shell. The modules are initially assembled within the assembly fixture. The fixture then moves to the pressing unit, where a first transport mechanism moves the product to the pressing table. The pressing mechanism presses the product together, connecting the bottom and top shells. Next, a transport robot in the functional testing unit moves the connected product to the testing device for functional testing. After the functional test, the robot moves the product to a testing fixture on a rotary conveyor. Driven by the rotary conveyor, the testing fixture passes a testing camera, which takes pictures of the product to check its quality. Finally, a robot in the unloading unit removes the tested product from the testing fixture and moves it to a receiving mechanism. The receiving mechanism has a tray for storing finished electronic control modules. The unloading robot places the product into the tray, completing the unloading process.

[0007] The fixture conveying device includes a first fixture conveying device and a second fixture conveying device. The first fixture conveying device is located on the machine base, and the second fixture conveying device is located inside the machine base. Circulating lifting mechanisms are provided on both sides of the fixture conveying devices. The first fixture conveying device is used to allow the assembly fixture to pass sequentially through the feeding assembly unit and the pressing unit, so that the product is assembled. After the product in the assembly fixture is removed by the first conveying mechanism, the empty assembly fixture continues to move to the circulating lifting mechanism under the conveying of the first fixture conveying device. After receiving the assembly fixture, the circulating lifting mechanism drives the assembly fixture to move downwards. Subsequently, the assembly fixture reaches the circulating lifting mechanism on the other side under the conveying of the second fixture conveying device, and then moves upwards under the drive of the circulating lifting mechanism, returning to the first fixture conveying device, realizing the cyclical use of the assembly fixture. In addition, the rotary conveying device is a closed conveying structure with the ends connected, allowing the testing fixture to move cyclically along a fixed path.

[0008] It should be noted that the lifting drive is provided on one side of the bottom shell feeding mechanism, the PCBA feeding mechanism, and the top shell feeding mechanism. When the assembly fixture reaches the above-mentioned mechanism, the lifting drive lifts the assembly fixture to a certain height. Then, the clamping drive drives the fixture clamping block to move, clamping the assembly fixture and completing the positioning, so that the feeding mechanism can carry out the feeding and assembly work. By setting the clamping drive, the accuracy of feeding can be effectively improved.

[0009] Furthermore, the first fixture conveying device includes two sets of conveyor belts arranged in parallel, and the lifting drive is located between the two sets of conveyor belts.

[0010] In the above technical solution, the two sides of the assembly fixture are placed on two sets of conveyor belts for conveying, and the lifting drive is located between the two sets of conveyor belts, which makes it easy to directly lift the assembly fixture.

[0011] Furthermore, the circulating lifting mechanism includes a circulating lifting drive device and a fixture placement platform connected to the circulating lifting drive device, with conveyor belts on both sides of the fixture placement platform.

[0012] In the above technical solution, the conveyor belt on the fixture placement platform is used to receive and send out the assembly fixture, and the lifting drive device drives the fixture placement platform to lift and lower, so that the assembly fixture can be transferred between the first fixture conveying device and the second fixture conveying device.

[0013] Furthermore, the tray conveying mechanism includes a tray lifting drive device, a tray receiving device, and a tray feeding assembly disposed between the tray lifting drive device and the tray receiving device. The tray lifting drive device is connected to a tray placement platform. The tray feeding assembly includes a first tray conveying device and a second tray conveying device arranged in parallel vertically. A tray clamping assembly is installed on the first tray conveying device.

[0014] In the above technical solution, the material tray loaded with material is sent to the material tray placement platform by the second material tray conveying device. Then, the material tray lifting drive device drives the material tray placement platform to move up. The material tray clamping assembly clamps the conveyed material tray. After the material in the material tray is removed, the material tray clamping assembly moves to the material tray receiving device under the drive of the first material tray conveying device. Then, the material tray clamping assembly releases the material tray, and the empty material tray is collected by the material tray receiving device.

[0015] Furthermore, the tray clamping assembly includes two tray clamping drive members, which are disposed opposite to each other on both sides of the first tray conveying device, and the output end of each tray clamping drive member is connected to a tray clamping block.

[0016] In the above technical solution, the material tray clamping drive unit clamps the material tray by driving the material tray clamping block to move toward the material tray on the material tray placement table.

[0017] Furthermore, the bottom shell feeding mechanism, the PCBA feeding mechanism, and the top shell feeding mechanism are each provided with a first feeding drive module, a second feeding drive module, and a material picking component. The second feeding drive module is connected to the output end of the first feeding drive module, and the material picking component is connected to the output end of the second feeding drive module.

[0018] In the above technical solution, the material picking component is used to pick up the bottom shell, PCBA and top shell in the material tray. The material picking component can move freely in the horizontal plane under the drive of the first feeding drive module and the second feeding drive module to complete the material picking and placing work.

[0019] Furthermore, the first conveying mechanism includes a first conveying drive module and a first conveying component, and the pressing mechanism includes a first positioning drive module, a second positioning drive module and a pressing component. The second positioning drive module is connected to the output end of the first positioning drive module, and the pressing component is connected to the output end of the second positioning drive module. The pressing component includes a pressing drive component and a pressure plate connected to the pressing drive component. A pressing detection sensor is provided on one side of the pressure plate.

[0020] In the above technical solution, the first conveying component can grasp the product that has been preliminarily assembled in the assembly fixture, and under the drive of the first conveying drive module, place the product on the pressing worktable. The pressing component can be accurately moved above the product on the pressing worktable under the drive of the first positioning drive module and the second positioning drive module. Then, the pressing drive component drives the pressure plate to press down and press the product, so that the bottom shell and the top shell are fastened together. During the pressing process, the pressing detection sensor on one side of the pressure plate performs mechanical monitoring of the pressing process to detect the pressing effect.

[0021] Furthermore, the pressing unit also includes a first transfer conveyor line, one end of which extends to the functional testing unit.

[0022] In the above technical solution, after the pressing mechanism presses the product, the first handling mechanism transports the pressed product to the first transfer conveyor line, and the first transfer conveyor line transports the product to the functional testing unit for the handling robot to pick up.

[0023] Furthermore, the detection unit also includes a second transfer conveyor line and a second handling mechanism, one end of the second transfer conveyor line extending to the functional testing unit, and the second handling mechanism including a second handling drive module and a second handling component.

[0024] In the above technical solution, after the product completes the functional test in the testing device, it is transported to the second transfer conveyor line by the handling robot. The second transfer conveyor line transports the product to the side of the second handling mechanism. Then, the second handling component grabs the product and moves it to the rotary conveyor under the drive of the second handling drive module. The product is placed in the testing fixture on the rotary conveyor for subsequent testing.

[0025] Furthermore, the functional testing unit also includes a sliding drive module, and the handling robot is connected to the output end of the sliding drive module.

[0026] In the above technical solution, the sliding drive module can drive the handling robot to move, making it easier for the handling robot to perform handling work.

[0027] The beneficial effects of this utility model are as follows:

[0028] This invention, through its cyclic conveying unit, feeding and assembly unit, pressing unit, functional testing unit, and detection unit, can automatically complete the assembly, testing, and inspection of the electronic control module, achieving high work efficiency. The cyclic conveying unit enables automatic loading and unloading of the assembly fixture, achieving self-circulation. Simultaneously, the rotary conveyor in the detection unit is a connected conveying structure, allowing the detection fixture to move repeatedly along a fixed path. This invention eliminates the need for additional manpower and resources for loading and unloading various fixtures, resulting in a high degree of automation, effectively saving operating costs and improving economic efficiency. Furthermore, the lifting and clamping drive components on the first fixture conveying device clamp and position the assembly fixture during loading, effectively improving the accuracy and reliability of the loading and assembly process.

[0054] The assembly and testing line for the electronic control module of this utility model will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0055] Please refer to Figures 1 to 16This embodiment provides an automated assembly and testing line for electronic control modules, used for assembling and functional testing of CAN modules. It includes a machine base 1, on which are provided a circulating conveying unit 2, a feeding assembly unit 3, a pressing unit 4, a functional testing unit 5, a detection unit 6, and a unloading unit 7. The feeding assembly unit 3 and the pressing unit 4 are located on one side of the circulating conveying unit 2, and the functional testing unit 5, the detection unit 6, and the unloading unit 7 are sequentially located on the side of the pressing unit 4 away from the feeding assembly unit 3. The circulating conveying unit 2 includes a jig conveying mechanism and a circulating lifting mechanism 23. The circulating lifting mechanism 23 is located on both sides of the jig conveying mechanism. The jig conveying mechanism includes a first jig conveying device 21 and a second jig conveying device 22 arranged in parallel, with opposite conveying directions. The loading and assembly unit 3 includes a bottom shell loading mechanism 31, a PCBA loading mechanism 32, and a top shell loading mechanism 33 arranged sequentially along the conveying direction of the first jig conveying device 21. Each of the bottom shell loading mechanism 31, PCBA loading mechanism 32, and top shell loading mechanism 33 has a separate tray conveying mechanism 37 on one side. The pressing unit 4 includes a first conveying mechanism 41, a pressing worktable 42, and a pressing mechanism 43. A conveying mechanism 41 is used to transport the products in the assembly fixture 26 to the pressing worktable 42; the functional testing unit 5 includes a conveying robot 51 and multiple sets of testing mechanisms 52, each set of testing mechanisms 52 including multiple testing devices 521; the detection unit 6 includes a rotary conveyor 61 and a detection component, the rotary conveyor 61 is equipped with multiple detection fixtures 611, the detection component includes multiple detection cameras 62, the rotary conveyor 61 is used to cyclically transport the detection fixtures 611 through the detection component, and the detection cameras 62 take pictures of the products in the passing detection fixtures 611 for visual inspection; the unloading unit 7 includes an unloading robot 71 and a receiving mechanism 72, the unloading robot 71 is used to transport the products in the detection fixtures 611 to the receiving mechanism 72.

[0056] It should be noted that the CAN module mainly consists of a bottom shell, a PCBA, and a front shell. The front shell is fastened onto the bottom shell, and the PCBA is located in the cavity formed after the bottom shell and front shell are assembled. Therefore, during assembly, the bottom shell, PCBA, and front shell must be assembled in that order. In addition, the bottom shell and front shell are provided with matching snap-fit ​​structures. By applying a certain pressure to the front shell, the bottom shell and front shell can be fastened together (for demonstration purposes, the assembly fixture 26 in the figure has a complete CAN module product 8 installed on it, which does not represent the actual installation situation).

[0057] Specifically, during operation of this production line, the assembly fixture 26 dedicated to the CAN module is placed on the first fixture conveying device 21. The bottom shell, PCBA, and top shell are all placed in their respective trays and conveyed by the tray conveying mechanisms 37 at their respective positions: the bottom shell feeding mechanism 31, the PCBA feeding mechanism 32, and the top shell feeding mechanism 33. Driven by the first fixture conveying device 21, the assembly fixture passes sequentially through the bottom shell feeding mechanism 31, the PCBA feeding mechanism 32, and the top shell feeding mechanism 33. The bottom shell feeding mechanism 31, the PCBA feeding mechanism 32, and the top shell feeding mechanism 33 take materials from their respective tray conveying mechanisms 37 and place the bottom shell, PCBA, and top shell into the assembly fixture 26 in sequence. This completes the initial assembly of the product within the assembly fixture 26, and then the assembly... When the assembly fixture 26 arrives at the pressing unit 4, the first conveying mechanism 41 transports the product in the assembly fixture 26 to the pressing worktable 42. The pressing mechanism 43 presses the product to make the bottom shell and the top shell snap together. Then, the conveying robot 51 in the functional testing unit 5 transports the snapped product to the testing device 521 for functional testing. After the functional test is completed, the conveying robot 51 transports the product to the detection unit 6. The product falls into the detection fixture 611 on the rotary conveyor 61. Driven by the rotary conveyor 61, the detection fixture 611 passes through the detection camera 62. The detection camera 62 takes pictures of the product to detect its quality. Then, the unloading robot 71 puts the product that has completed the test in the detection fixture 611 into the receiving mechanism 72 for collection.

[0058] Among them, such as Figure 5 As shown, the first fixture conveying device 21 is located on the machine base 1, and the second fixture conveying device 22 is located inside the machine base 1. Circulating lifting mechanisms 23 are provided on both sides of the fixture conveying devices. After the products in the assembly fixture 26 are transported away by the first conveying mechanism 41, the empty assembly fixture 26 continues to move to the circulating lifting mechanism 23 under the conveying of the first fixture conveying device 21. After receiving the assembly fixture 26, the circulating lifting mechanism 23 drives the assembly fixture 26 to move downwards. Subsequently, the assembly fixture 26 reaches the circulating lifting mechanism 23 on the other side under the conveying of the second fixture conveying device 22, and then moves upwards under the drive of the circulating lifting mechanism 23, returning to the first fixture conveying device 21. This achieves the self-circulating use of the assembly fixture 26, eliminating the need for additional manpower and resources to load the assembly fixture 26. In addition, the rotary conveyor 61 is a conveying structure with the ends connected, allowing the inspection fixture 611 to move repeatedly along a fixed path. The inspection fixture 611 can be reused without the need for additional loading.

[0059] Please refer to Figure 2 and Figure 3In this embodiment, both the first jig conveying device 21 and the second jig conveying device 22 include two sets of conveyor belts 27 arranged in parallel. A plurality of lifting drive members 24 are provided between the two sets of conveyor belts 27 of the first jig conveying device 21. Clamping drive members 25 are provided on both sides of the lifting drive members 24. The clamping drive members 25 are located on the outside of the two sets of conveyor belts 27. The output end of the clamping drive member 25 is connected to a jig clamping block 251.

[0060] Preferably, two lifting drive units 24 are provided at corresponding positions of the bottom shell feeding mechanism 31, PCBA feeding mechanism 32, and top shell feeding mechanism 33, which can perform feeding and assembly work of two products simultaneously. When the assembly fixture 26 reaches the above-mentioned mechanism, the lifting drive unit 24 lifts the assembly fixture 26 to the same height as the fixture clamping block 251. Then, the clamping drive units 25 on both sides drive the fixture clamping block 251 to move, clamping the assembly fixture 26 to complete the positioning, so that each feeding mechanism can feed materials, thereby improving the accuracy of feeding.

[0061] Please refer to Figure 6 In this embodiment, the circulating lifting mechanism 23 includes a circulating lifting drive device 231 and a fixture placement platform 232 connected to the circulating lifting drive device 231. The fixture placement platform 232 is also provided with two parallel conveyor belts 27, so that the assembly fixture 26 can be received and sent out. The lifting drive device drives the fixture placement platform 232 to move up and down, so that the assembly fixture 26 can be transferred between the first fixture conveying device 21 and the second fixture conveying device 22.

[0062] Please refer to Figure 3 , Figure 8 and Figure 9 In this embodiment, the bottom shell feeding mechanism 31, the PCBA feeding mechanism 32, and the top shell feeding mechanism 33 are each equipped with a first feeding drive module 34, a second feeding drive module 35, and a material picking component 36. The first feeding drive module 34 and the second feeding drive module 35 are arranged vertically. The second feeding drive module 35 is connected to the output end of the first feeding drive module 34. The material picking component 36 is connected to the output end of the second feeding drive module 35. The material picking component 36 is used to pick up the bottom shell, PCBA, and top shell in the material tray. The material picking component 36 can move freely in the horizontal plane under the action of the first feeding drive module 34 and the second feeding drive module 35 to complete the material picking and placing work.

[0063] It is worth mentioning that the material handling component 36 includes a suction nozzle (not specifically shown in the figure) for picking up materials, and a rotary motor (not specifically shown in the figure) connected to the suction nozzle. The rotary motor can drive the suction nozzle to rotate and adjust the picked-up materials (i.e., bottom shell, PCBA, and top shell) to a suitable position. The material handling component 36 is also connected to a lifting motor 361 to facilitate the lifting and lowering of the suction nozzle for easy material handling. In addition, the bottom shell feeding mechanism 31, PCBA feeding mechanism 32, and top shell feeding mechanism 33 are all equipped with CCD cameras 38. After picking up materials, the material handling component 36 moves above the CCD camera 38 to take pictures and detect the materials. The position and offset data of the materials are obtained through the pictures and transmitted to the control program to ensure the accuracy of material loading.

[0064] Please refer to Figure 7 Taking the tray conveying mechanism 37 corresponding to the bottom shell feeding mechanism 31 as an example, the tray conveying mechanism 37 includes a tray lifting drive device 371, a tray receiving device 372, and a tray feeding mechanism disposed between the tray lifting drive device 371 and the tray receiving device 372. The tray lifting drive device 371 is connected to a tray placement platform 3711. The tray feeding mechanism includes a first tray conveying device 373 and a second tray conveying device 374 arranged in parallel. The first tray conveying device 373 is equipped with... The tray clamping assembly includes two tray clamping drive units 3731, which are disposed opposite to each other on both sides of the first tray conveying device 373. The tray clamping drive units 3731 can move under the drive of the first tray conveying device 373. The output end of the tray clamping drive unit 3731 is connected to a tray clamping block 3732. The tray clamping drive unit 3731 clamps the tray by driving the tray clamping block 3732 to move toward the tray on the tray placement platform 3711.

[0065] Specifically, the material-filled tray is conveyed to the tray placement platform 3711 via the second tray conveyor 374. Then, the tray lifting drive 371 drives the tray placement platform 3711 upwards, and the tray clamping assembly clamps the conveyed tray. After the material in the tray is removed, the tray clamping assembly moves to the tray receiving device 372 under the drive of the first tray conveyor 373. The tray clamping assembly then releases the tray, and the empty trays are stacked and collected by the tray receiving device 372. In the diagram, the material tray receiving device 372 is a common stacking receiving mechanism in the prior art. Taking the diagram as an example, it usually has a receiving platform 3721 and a receiving rack 3722. After the material tray is conveyed by the first material tray conveying device 373, it falls onto the receiving platform 3721. The receiving platform 3721 drives the material basket to move to the bottom of the receiving rack 3722. Then, the lifting structure makes the material trays enter one by one from the bottom of the receiving rack 3722 to realize the stacking of material trays. Its specific structure and principle will not be described in detail here.

[0066] The first tray conveying device 373 and the second tray conveying device 374 are each equipped with two parallel conveyor belts 27, and the two tray clamping drive units 3731 are respectively installed on the two sets of conveyor belts 27 of the first tray conveying device 373.

[0067] It is worth mentioning that the above description of the tray conveying mechanism 37 is based on the tray conveying mechanism 37 at the bottom shell feeding mechanism 31. The tray conveying mechanisms 37 at the PCBA feeding mechanism 32 and the top shell feeding mechanism 33 have the same structure and principle as the tray conveying mechanism 37 described above, and will not be elaborated on here.

[0068] Please refer to Figures 10 to 12 In this embodiment, the first transport mechanism 41 includes a first transport drive module 411 and a first transport assembly 412. The pressing mechanism 43 includes a first positioning drive module 431, a second positioning drive module 432, and a pressing assembly 433. The second positioning drive module 432 is vertically connected to the first positioning drive module 431. The pressing assembly 433 is connected to the output end of the second positioning drive module 432. The pressing assembly 433 includes a pressing drive component 4331 and a pressure plate 4332 connected to the pressing drive component 4331. A pressing detection sensor 4333 is provided on one side of the pressure plate 4332. The first transport assembly... 412 can grasp the product that has completed preliminary assembly in the assembly fixture 26, and under the drive of the first transport drive module 411, place the product on the pressing worktable 42. The pressing component 433 can accurately move above the product on the pressing worktable 42 under the drive of the first positioning drive module 431 and the second positioning drive module 432. Then the pressing drive component 4331 drives the pressure plate 4332 to press down and press the product, so that the bottom shell and the top shell are fastened together. At the same time as pressing, the pressing detection sensor 4333 on one side of the pressure plate 4332 performs mechanical monitoring of the pressing process to detect the pressing effect.

[0069] In addition, a pressing NG conveyor belt 45 is provided on one side of the pressing worktable 42. When the pressing detection sensor 4333 detects poor pressing, the first handling mechanism 41 takes away the defective product and places it on the pressing NG conveyor belt 45 to screen out the defective product and prevent it from flowing into the next process.

[0070] It should be noted that in this embodiment, the first conveying component 412 uses a cylinder to drive the clamping block to grip the product. Since the product is not fully connected after initial assembly, it is easy for it to fall off when using a suction nozzle. Therefore, gripping the product by clamping both sides can effectively prevent the product from falling off.

[0071] Please refer to Figure 1 and Figure 13In this embodiment, the pressing unit 4 is provided with a first transfer conveyor line 44, and the testing unit 6 is provided with a second transfer conveyor line 65. Both the first transfer conveyor line 44 and the second transfer conveyor line 65 extend to the functional testing unit 5. After the product is pressed on the pressing workbench 42, the first handling mechanism 41 handles the qualified product to the first transfer conveyor line 44, and the first transfer conveyor line 44 transports the product to the functional testing unit 5. The handling robot 51 then places the delivered product into the testing device 521. After the product is tested in the testing device 521, the handling robot 51 places the product on the second transfer conveyor line 65, and the product is sent to the testing unit 6 through the second transfer conveyor line 65.

[0072] Specifically, the functional test unit 5 is also equipped with a sliding drive module 53. The handling robot 51 is installed on the sliding drive module 53. The sliding drive module 53 can drive the handling robot 51 to move horizontally so that the handling robot 51 can pick up and put down materials.

[0073] It is worth mentioning that, such as Figure 13 As shown, the testing mechanism 52 in this embodiment is provided in 4 groups, each group including 4 testing devices 521. The handling robot 51 is connected to the suction structure 511. The suction structure 511 can pick up 4 products at a time, so that the handling robot 51 can put 4 products into the 4 testing devices 521 of a set of testing mechanisms 52 at the same time, which effectively improves the handling efficiency.

[0074] Please refer to Figure 14 and Figure 15 In this embodiment, the functional testing unit 5 is provided with a second transport mechanism 64, which is located on one side of the second transfer conveyor line 65. The second transport mechanism 64 includes a second transport drive module 641 and a second transport component 642. After the product completes the functional test in the testing device 521, it is transported to the second transfer conveyor line 65 by the transport robot 51. The second transfer conveyor line 65 transports the product to the side of the second transport mechanism 64. Then, the second transport component 642 grabs the product and moves it above the rotary conveyor 61 under the drive of the second transport drive module 641. The product is placed in the testing fixture 611 on the rotary conveyor 61 for subsequent testing.

[0075] One side of the inspection component is also equipped with a laser engraving machine 63, which is used to mark the product. Specifically, according to... Figure 15The rotary conveyor 61 conveys products in a clockwise direction. After being marked by the laser engraving machine 63, the products arrive at the inspection camera 62 for inspection. Multiple inspection cameras 62 are provided to perform appearance inspection, pin inspection, etc. on the products. The second handling mechanism 64 is also equipped with an inspection NG conveyor belt 66. Defective products detected by the inspection camera 62 are transported to the inspection NG conveyor belt 66 by the second handling mechanism 64, while qualified products move with the rotary conveyor 61 to the side of the unloading robot 71 and are carried away by the unloading robot 71.

[0076] Specifically, the second conveying component 642 in this embodiment is provided with a suction nozzle (not shown in the figure). The suction nozzle is used to pick up the product to complete the picking and placing of materials. In addition, grippers, two clamping blocks or other structures can also be provided, as long as they can satisfy the function of gripping the product.

[0077] Please refer to Figure 16 In this embodiment, the receiving mechanism 72 is provided with a tray for receiving finished electronic control modules. The unloading robot 71 picks up the inspected products and puts them into the tray at the receiving mechanism 72 to complete the unloading and collection of finished products. The receiving mechanism 72 is the same in structure and principle as the tray conveying mechanism 37 described above, and will not be described in detail here.

[0078] The drive module mentioned above can be a linear motor or linear module, and the drive component can be a cylinder, etc. These are all common structures in the prior art, and can be flexibly selected according to actual needs.

[0079] Please refer to Figures 1 to 16 Taking the assembly and testing process of a CAN module product as an example, the main steps are as follows:

[0080] Under the conveying of the first fixture conveying device 21, the assembly fixture 26 reaches the bottom shell feeding mechanism 31, which places the bottom shell into the assembly fixture 26. Then, the assembly fixture 26 reaches the PCBA feeding mechanism 32, which places the PCBA on the bottom shell. Next, the assembly fixture 26 reaches the top shell feeding mechanism 33, which places the top shell on the bottom shell, thus closing the PCBA and obtaining a pre-assembled product. The assembly fixture 26 then reaches the pressing unit 4, where the first transport component 412 transports the product from the assembly fixture 26 to the pressing worktable 42. The pressing component 433 moves above the product and presses it. After pressing, the first transport component 412 transports the product to the first transfer conveyor line 44, where the transport robot 51 grasps the product from the first transfer conveyor line. The product on 44 is placed in the testing device 521. After the product completes the test, the handling robot 51 moves the product in the testing device 521 to the second transfer conveyor line 65. The second transfer conveyor line 65 transports the product to one side of the second handling component 642. The second handling component 642 transports the product to the inspection fixture 611 on the rotary conveyor 61. The inspection fixture 611 is transported by the rotary conveyor 61 and first reaches the laser engraving machine 63, which marks the product. Then the inspection fixture 611 reaches each inspection camera 62, which takes pictures of the product for inspection. After the inspection is completed, the inspection fixture 611 reaches the unloading robot 71, which moves the product in the inspection fixture 611 to the material tray of the receiving mechanism 72. Thus, the assembly and testing of a CAN module product is completed.

[0081] In some embodiments, a soldering mechanism (not shown in the figure) is also provided between the PCBA feeding mechanism 32 and the shell feeding mechanism 33. The soldering mechanism is equipped with a laser soldering head and is used to perform laser soldering on the placed PCBA before the shell is assembled.
