[0002] PCBA is one of the key components of electrical equipment. PCBA is a circuit board obtained by surface mount technology (SMT) on a bare PCB and then through DIP insertion, which means assembling various electronic components onto the PCB using surface mount technology. The charging current, operating voltage, and power consumption of LED switch circuit boards directly affect the subsequent performance and yield of LED switches. Therefore, testing the various performance characteristics of LED switch circuit boards before handover is an essential and very important step.

[0003] In the current technology, the testing of LED switch PCBA is mainly carried out manually. That is, after the PCB has gone through processes such as insertion and soldering to obtain the PCBA, technicians use testing tools such as multimeters and oscilloscopes to test the various performance of the PCBA. However, manual testing has drawbacks such as low testing efficiency and high labor intensity. Therefore, developing a set of equipment that can replace manual testing has been a long-standing issue in the field of PCBA testing. Utility Model Content

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Please see Figures 1 to 6 An LED switch circuit board performance testing device includes a main control box 100, a support base 200, a testing base plate 300, a driving unit 400, a testing unit 500, and a marking unit 600. The testing base plate 300 is mounted on the main control box 100 and has several testing slots 310 formed on it. The support base 200 is mounted on the main control box 100, and the driving unit 400 is mounted on the support base 200. The testing unit 500 and the marking unit 600 are respectively connected to the driving unit 400 and are located above the testing base plate 300. The driving unit 400 drives the testing unit 500 and the marking unit 600 to move away from or closer to the testing base plate 300.

[0034] Specifically, in this embodiment, multiple detection slots 310 are formed on the detection base plate 300, and PCBAs to be tested are placed in each of the multiple detection slots 310. During testing, the drive unit 400 is activated, which drives the detection unit 500 and the marking unit 600 to move downwards. When they reach the set position, the detection unit 500 contacts the PCBA to be tested in the detection slot 310. Through contact, the charging current, operating voltage, power consumption, and other performance parameters of the PCBA are tested. If the PCBA is found to be defective during the testing process, the marking unit 600 will mark the defective PCBA for subsequent operations. Finally, the drive unit 400, the detection unit 500, and the marking unit 600 achieve automated detection and marking, thereby reducing manual operation and labor intensity. In addition, since the detection unit 500 can detect PCBAs in multiple detection slots 310 simultaneously, the detection efficiency of PCBAs can be improved and the detection quality can be ensured.

[0035] To improve the safety of LED switch PCBA during testing, in this embodiment, an emergency stop switch 110 is provided in the middle of the operating surface of the main control box 100, and start switches 120 are provided on both sides of the operating surface. When testing is required, the operator must simultaneously turn on the start switches 120 on both sides to enable the testing equipment to run, thereby improving the safety of the operator. In case of an emergency during testing, the emergency stop switch 110 can be turned on to ensure safe testing and improve safety performance.

[0036] In addition, during the testing process, the operator needs to place the PCBA to be tested into the test slot 310, and the drive unit 400 needs to drive the test unit 500 to move downward. In order to ensure the safety of the operator, safety light curtains 210 are respectively provided on both sides of the support base 200. The operating space is monitored through the safety light curtains 210, thereby improving the safety of the operator.

[0037] In order to facilitate the use of the testing equipment, a handle 130 is provided on the side of the main control box 100. The testing equipment can be easily picked up and moved through the handle 130, so as to facilitate the use of the testing equipment in different places, thereby improving the portability of the testing equipment.

[0038] Please see Figure 3 In this embodiment, to drive the detection unit 500 and the marking unit 600, the driving unit 400 includes a driving component 410, a guide rod 420, and a lifting plate 430. The driving component 410 is mounted on the support base 200, and the guide rods 420 are respectively provided on both sides of the support base 200. The lifting plate 430 is connected to the driving component 410 and the guide rods 420 respectively. The driving component 410 drives the lifting plate 430 to move up and down along the guide rods 420. When driving, the driving component 410 is activated. The driving component 410 is a cylinder. When the driving component 410 is working, it drives the lifting plate 430 to move. The lifting plate 430 slides up and down along the guide rods 420. During the up and down movement of the lifting plate 430, it moves the detection unit 500 and the marking unit 600 connected to it, thereby driving the detection unit 500 and the marking unit 600, realizing automated detection, thereby improving detection efficiency and reducing manual labor intensity.

[0039] Please see Figure 4In order to test the PCBA in the test slot 310, the test unit 500 in this embodiment includes a connecting post 510 and a test pin plate 520. One end of the connecting post 510 is connected to the lifting plate 430, and the other end of the connecting post 510 is connected to the test pin plate 520. Thus, the test pin plate 520 can be moved by the movement of the lifting plate 430. At the same time, the test pin plate 520 is provided with a probe group 530 corresponding to the number of test slots 310. When the test pin plate 520 moves, it will bring the probe group 530 to contact the PCBA in the corresponding test slot 310. Through the contact of the probe group 530, the charging current, working voltage, power consumption and other performance of the PCBA can be tested, realizing automated testing.

[0040] In addition, to ensure testing accuracy, it is necessary to prevent the PCBA in the test slot 310 from shaking or shifting during the testing process. Therefore, in this embodiment, a pressure bar group 540 corresponding to the number of test slots 310 is also provided on the bottom surface of the test pin plate 520. When the lifting plate 430 moves the test pin plate 520 downward, the pressure bar group 540 will press the PCBA in the corresponding test slot 310 to prevent the PCBA from shaking or shifting during the testing process, which would cause poor contact with the probe group 530 and ensure the accuracy of the PCBA during testing.

[0041] Please see Figures 4 to 6 During testing of LED switch PCBAs, defective products may be detected. To facilitate subsequent differentiation of defective products, they need to be marked. Therefore, the marking unit 600 in this embodiment includes a lateral movement module 610, a connecting plate 620, a marking driver 630, a fixing plate 640, a dotting pen 650, and a fastening handle 660. The lateral movement module 610 is connected to the lifting plate 430, and the connecting plate 620 is connected to the lateral movement module 610. The marking driver 630 is mounted on the connecting plate 620, and the fixing plate 640 is connected to the marking driver 630. The dotting pen 650 is set on the fixing plate 640 and fixed by the fastening handle 660.

[0042] When the drive unit 400 drives the detection unit 500 and the marking unit 600 to move to the set position, and the detection unit 500 detects that the PCBA is defective, the lateral movement module 610 will drive the dotting pen 650 to move above the corresponding PCBA, and then the marking drive unit 630 will drive the dotting pen 650 to move downward. The marking drive unit 630 is a cylinder. When the dotting pen 650 moves to the set position, it will cooperate with the PCBA and apply a mark to the PCBA, thereby marking the defective PCBA and facilitating the subsequent differentiation of defective products.

[0043] In order to facilitate the movement of the horizontal moving module 610 to drive the dotting pen 650 to move back and forth between the detection slots 310, a movable slot 550 is also provided on the detection pin plate 520. The dotting pen 650 will pass through the movable slot 550, so that the dotting pen 650 can cooperate with the PCBA in the multiple detection slots 310.

[0044] Furthermore, when the dot pen 650 needs to be replaced after a period of use, the fastening handle 660 can be turned to remove the dot pen 650 from the fixing plate 640, and a new dot pen 650 can be replaced. Then, the fastening handle 660 can be tightened to facilitate the replacement of the dot pen 650 and make it easier to mark defective products.

[0045] Finally, to ensure that the dot pen 650 does not exceed the range of the movable slot 550 when moving, sensors 670 are respectively provided at both ends of the lateral movement module 610, and the connecting plate 620 is connected to the sensing element 680 that cooperates with the sensor 670. Through the sensing between the sensing element 680 and the sensor 670, the moving position of the dot pen 650 is monitored, thereby ensuring that the lateral movement module 610 does not exceed the range of the movable slot 310 when driving the dot pen 650 to move, making the overall design of the testing equipment more reasonable.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
