Description

Technical Field

[0001] The present invention relates to the technical field of intelligent electric control equipment production, and in particular to an automatic assembly and testing line for intelligent electric control modules. Background Art

[0002] The CAN module is an intelligent electronic control device that forwards communication data between the electronic control devices of the vehicle, thereby realizing a regional network control system for the on-board electronic control devices of the vehicle. The shell of the CAN module is mainly composed of a bottom shell and a top shell that fit together, with a PCBA installed inside. During production, after the bottom shell, top shell and PCBA are assembled, the assembled product needs to be subjected to corresponding functional tests to ensure the quality and reliability of the final product.

[0003] At present, the assembly and testing of module products require the use of jigs, which are transported by conveyor belts. After the assembly and testing work is completed, the jig reaches the end of the conveyor belt for unloading and collection, and then the jig is manually transferred to the starting point of the conveyor belt and then loaded back onto the conveyor belt.

Among them, the circulating conveying unit 2 includes a jig conveying mechanism and a circulating lifting mechanism 23, the circulating lifting mechanism 23 is arranged 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 up and down, and the conveying directions of the first jig conveying device 21 and the second jig conveying device 22 are opposite; the feeding assembly unit 3 includes a bottom shell feeding mechanism 31, a PCBA feeding mechanism 32 and a surface shell feeding mechanism 33 which are arranged in sequence along the conveying direction of the first jig conveying device 21, and a tray conveying mechanism 37 is separately provided on one side of the bottom shell feeding mechanism 31, the PCBA feeding mechanism 32 and the surface shell feeding mechanism 33; the pressing unit 4 includes a first conveying mechanism 41, a pressing workbench 42 and a pressing mechanism 43, the first A conveying mechanism 41 is used to convey the product in the assembly jig 26 to the pressing workbench 42; the functional testing unit 5 includes a conveying robot 51 and multiple groups of testing mechanisms 52, each group of testing mechanisms 52 includes multiple testing devices 521; the detection unit 6 includes a rotary conveyor 61 and a detection component, the rotary conveyor 61 is provided with multiple detection jigs 611, the detection component includes multiple detection cameras 62, the rotary conveyor 61 is used to cyclically convey the detection jig 611 through the detection component, and the detection camera 62 takes pictures of the products in the passing detection jig 611 for visual inspection; the unloading unit 7 includes a unloading robot 71 and a receiving mechanism 72, the unloading robot 71 is used to convey the products in the detection jig 611 to the receiving mechanism 72.

[0046] It should be noted that the CAN module is mainly composed of a base shell, a PCBA and a face shell. The face shell is buckled on the base shell, and the PCBA is located in a cavity formed after the base shell and the face shell are assembled. Therefore, when assembling, it is necessary to assemble the base shell, the PCBA and the face shell in this order. In addition, the base shell and the face shell are provided with matching snap-on structures. By applying a certain pressure to the face shell, the base shell and the face shell can be buckled together (for demonstration purposes, the assembly jig 26 in the figure has been installed with a complete CAN module product 8, which does not represent the actual installation situation).

[0047] Specifically, when the production line is working, the assembly jig 26 dedicated to the CAN module is placed on the first jig conveying device 21, the bottom shell, PCBA and face shell are all placed in corresponding material trays, and are respectively conveyed by the material tray conveying mechanisms 37 at the respective positions of the bottom shell feeding mechanism 31, the PCBA feeding mechanism 32 and the face shell feeding mechanism 33. Driven by the first jig conveying device 21, the combined jig passes through the bottom shell feeding mechanism 31, the PCBA feeding mechanism 32 and the face shell feeding mechanism 33 in turn. The bottom shell feeding mechanism 31, the PCBA feeding mechanism 32 and the face shell feeding mechanism 33 take materials from their respective material tray conveying mechanisms 37, and place the bottom shell, PCBA and face shell in the assembly jig 26 in turn, thereby completing the preliminary assembly of the product in the assembly jig 26, and then the assembly The assembly jig 26 arrives at the pressing unit 4, and the first conveying mechanism 41 conveys the product in the assembly jig 26 to the pressing workbench 42.

[0048] Among them, Figure 5As shown, the first jig conveying device 21 is arranged on the machine 1, the second jig conveying device 22 is arranged inside the machine 1, and circulating lifting mechanisms 23 are arranged on both sides of the jig conveying devices. After the product in the assembly jig 26 is transported away by the first transporting mechanism 41, the empty assembly jig 26 continues to move to the circulating lifting mechanism 23 under the transportation of the first jig conveying device 21. After the circulating lifting mechanism 23 receives the assembly jig 26, it drives the assembly jig 26 to move downward. Subsequently, the assembly jig 26 reaches the circulating lifting mechanism 23 on the other side under the transportation of the second jig conveying device 22, and then moves upward under the drive of the circulating lifting mechanism 23 and returns to the first jig conveying device 21, thereby realizing the self-circulation use of the assembly jig 26, without the need to consume additional manpower and material resources to load the assembly jig 26; in addition, the rotary conveying device 61 is a transmission structure connected end to end, so that the detection jig 611 can be repeatedly moved in a cycle along a fixed path, and the detection jig 611 can be reused without the need for additional loading of the detection jig 611.

[0049] Please refer to Figure 2 and Figure 3 In this embodiment, the first jig conveying device 21 and the second jig conveying device 22 both include two sets of conveyor belts 27 arranged in parallel, wherein a plurality of lifting driving members 24 are arranged between the two sets of conveyor belts 27 of the first jig conveying device 21, and clamping driving members 25 are arranged on both sides of the lifting driving members 24, and the clamping driving members 25 are located on the outside of the two sets of conveyor belts 27, and the output end of the clamping driving member 25 is connected to the jig clamping block 251.

[0050] Preferably, two lifting drive components 24 are provided at positions corresponding to the bottom shell feeding mechanism 31, the PCBA feeding mechanism 32 and the surface shell feeding mechanism 33, so that the feeding and assembly of two products can be carried out simultaneously. When the assembly jig 26 reaches the above-mentioned mechanism, the lifting drive component 24 lifts the assembly jig 26 to the same height as the jig clamp 251, and then the clamping drive components 25 on both sides drive the jig clamp 251 to move, clamping the assembly jig 26 to complete the positioning, so that each feeding mechanism can feed the materials, thereby improving the feeding accuracy.

[0051] Please refer to Figure 6 In this embodiment, the circulating lifting mechanism 23 includes a circulating lifting drive device 231 and a fixture placement table 232 connected to the circulating lifting drive device 231. The fixture placement table 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 table 232 to lift and lower so that the assembly fixture 26 can be transferred between the first fixture conveying device 21 and the second fixture conveying device 22.

[0052] Please refer to Figure 3 , Figure 8 and Fig. 9In this embodiment, the bottom shell feeding mechanism 31, the PCBA feeding mechanism 32 and the surface shell feeding mechanism 33 are all provided with a first feeding drive module 34, a second feeding drive module 35 and a picking component 36. The first feeding drive module 34 and the second feeding drive module 35 are vertically arranged, the second feeding drive module 35 is connected to the output end of the first feeding drive module 34, and the picking component 36 is connected to the output end of the second feeding drive module 35. The picking component 36 is used to suck the bottom shell, PCBA and surface shell in the material tray. The 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.

[0053] It is worth mentioning that the material picking component 36 includes a suction nozzle (not specifically shown in the figure) that can suck materials, and a rotating motor (not specifically shown in the figure) connected to the suction nozzle. The rotating motor can drive the suction nozzle to rotate and adjust the sucked material (i.e., the bottom shell, PCBA, and surface shell) to a suitable orientation. The material picking component 36 is also connected to a lifting motor 361 to facilitate the control of the lifting and lowering of the suction nozzle to facilitate the picking and placing of materials. In addition, the bottom shell feeding mechanism 31, the PCBA feeding mechanism 32, and the surface shell feeding mechanism 33 are all provided with a CCD camera 38. After picking up the material, the material picking component 36 first moves to the top of the CCD camera 38 for photo detection, and obtains the material's orientation and offset data through the photographed image, and transmits the data to the control program to ensure the accuracy of the material loading.

[0054] Please refer to Figure 7 Taking the tray conveying mechanism 37 corresponding to the bottom shell loading mechanism 31 as an example, the tray conveying mechanism 37 includes a tray lifting driving device 371, a tray receiving device 372, and a tray feeding mechanism arranged between the tray lifting driving device 371 and the tray receiving device 372. The tray lifting driving device 371 is connected to a tray placing table 3711. The tray feeding mechanism includes a first tray conveying device 373 and a second tray conveying device 374 arranged in parallel up and down. The first tray conveying device 373 is installed There is a tray clamping assembly, which includes two tray clamping driving members 3731. The two tray clamping driving members 3731 are relatively arranged on both sides of the first tray conveying device 373. The tray clamping driving members 3731 can move under the drive of the first tray conveying device 373. The output end of the tray clamping driving member 3731 is connected to a tray clamping block 3732. The tray clamping driving member 3731 clamps the tray by driving the tray clamping block 3732 to move toward the tray on the tray placement table 3711.

[0055] Specifically, the tray loaded with materials is delivered to the tray placement table 3711 by the second tray conveying device 374, and then the tray lifting drive device 371 drives the tray placement table 3711 to move up, and the tray clamping assembly clamps the delivered tray, and after the material in the tray is taken out, the tray clamping assembly is driven by the first tray conveying device 373 to move to the tray collecting device 372, and then the tray clamping assembly releases the tray, and the empty trays are stacked and collected by the tray collecting device 372. In the figure, the material tray collecting device 372 is a common stacking material collecting mechanism in the prior art. Taking the figure as an example, it is usually provided with a material receiving platform 3721 and a material collecting rack 3722. The material tray falls on the material receiving platform 3721 after being transported by the first material tray conveying device 373. The material receiving platform 3721 drives the material basket to move to the bottom of the material collecting rack 3722, and then the material trays are allowed to enter one by one from the bottom of the material collecting rack 3722 through the lifting structure to realize the stacking of the material trays. Its specific structure and principle will not be introduced in detail here.

[0056] The first tray conveying device 373 and the second tray conveying device 374 are both provided with two parallel conveyor belts 27 , and the two tray clamping driving members 3731 are respectively installed on the two groups of conveyor belts 27 of the first tray conveying device 373 .

[0057] 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 loading mechanism 31 as an example. The tray conveying mechanism 37 at the PCBA loading mechanism 32 and the surface shell loading mechanism 33 have the same structure and principle as the above tray conveying mechanism 37, and will not be elaborated on here.

[0058] Please refer to Figures 10 to 12In 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 member 4331, and a pressing plate 4332 connected to the pressing drive member 4331, a pressing detection sensor 4333 is provided on one side of the pressing plate 4332, and the first transport assembly 412 can grab the product that has completed the preliminary assembly in the assembly fixture 26, and place the product on the pressing workbench 42 under the drive of the first transport drive module 411. The pressing component 433 can be accurately moved to the top of the product on the pressing workbench 42 under the drive of the first positioning drive module 431 and the second positioning drive module 432. Then the pressing drive member 4331 drives the pressing plate 4332 to press down to press the product so that the bottom shell and the front shell are snapped together. While pressing, the pressing detection sensor 4333 on one side of the pressing plate 4332 mechanically monitors the pressing process to detect the pressing effect.

[0059] In addition, a pressing NG conveyor belt 45 is provided on one side of the pressing workbench 42. When the pressing detection sensor 4333 detects poor pressing, the first transport mechanism 41 takes away the defective products and places them on the pressing NG conveyor belt 45 to screen out the defective products and prevent them from flowing into the next process.

[0060] It should be noted that the first transport component 412 in the present embodiment grabs the product by means of a cylinder-driven clamping block. Since the product is not fully connected after the initial assembly, it is easy for it to fall off when it is sucked by a suction nozzle. Therefore, grabbing the product by clamping both sides of the product can effectively avoid the occurrence of falling off.

[0061] Please refer to Figure 1 and Fig.13 In this embodiment, the laminating unit 4 is provided with a first transfer conveyor line 44, and the detection unit 6 is provided with a second transfer conveyor line 65. The first transfer conveyor line 44 and the second transfer conveyor line 65 both extend to the functional testing unit 5.
