Description

Technical Field

[0001] This utility model relates to the technical field of bare plate testing devices for vehicles, specifically a flying needle type bare plate testing device for vehicles. Background Technology

[0002] In the manufacturing process of electronic devices, the quality inspection of bare circuit boards is crucial. Probes are used to contact test points on the bare board, applying electrical signals and detecting the feedback signals to determine the electrical connectivity, short circuits, open circuits, and whether basic electrical parameters meet design standards. Current methods for inspecting bare boards often involve conveying them to the inspection position via a conveyor belt and then using a flying probe-type bare board testing device. During inspection, clamps are typically used to hold and fix the side walls of the bare board. However, existing clamping structures generally only compress the side panels, failing to simultaneously clamp the top and bottom outer walls. This leads to board misalignment during inspection, introducing inspection errors and hindering the improvement of inspection accuracy. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] Example 1: As Figure 1 and 2 The system includes a feeding platform, which includes a side plate 100. A clamping assembly, including a clamping plate 350, is fixedly installed on the inner wall of the side plate 100. The feeding platform includes a conveyor roller 200 and a conveyor belt 210 rotatably connected to the outer wall of the conveyor roller 200. Two conveyor belts 210 are symmetrically arranged on the left and right sides. The inner wall of the conveyor belt 210 has a first sink 220 and a second sink 230. The clamping plates 350 are slidably connected to the inner walls of the first sink 220 and the second sink 230. There are two clamping plates 350 symmetrically arranged on the left and right sides. The two clamping plates 350 are used to clamp and fix the bare plate on both sides of the carrier. A flying probe type bare plate testing device is fixedly installed on the top of the side plate 100. The flying probe type bare plate testing device is located above the clamping assembly.

[0025] The specific application scenario of this embodiment is as follows: By setting up a feeding platform for conveying bare plates of the carrier for continuous testing, and by setting up clamping plates 350 for clamping and fixing both sides of the bare plates of the carrier, the practicality of the equipment can be improved when testing the bare plates of the carrier. By setting up a first sink trough 220 and a second sink trough 230 for use together, the clamping plates 350 can be slidably connected to the top of the conveyor belt 210, so that the clamping plates 350 can be adapted to the side walls of the bare plates of the carrier, and the bare plates of the carrier can be clamped and fixed stably.

[0026] Example 2: Figure 1 and Figure 2 A servo motor for driving the conveyor roller 200 is fixedly installed on the inner wall of the side plate 100. Adjacent conveyor rollers 200 are connected in sequence by a synchronous pulley and a synchronous belt. The outer wall of the conveyor roller 200 is connected to the outer wall of the output shaft of the servo motor by a synchronous pulley and a synchronous belt. The bottom outer wall of the side plate 100 is welded to the support leg 110.

[0027] The specific application scenario of this embodiment is as follows: by setting a conveyor roller 200 for mounting the conveyor belt 210, and by setting a synchronous pulley, a synchronous belt and a servo motor to work together to drive the conveyor belt 210 to rotate, so that the bare plate of the carrier is transported through the conveyor belt 210 for inspection and use.

[0028] Example 3: As Figure 3 and Figure 4 A support frame 341 is welded to the outer wall of the clamping plate 350. A slide block 340 is connected to the end of the support frame 341. A slide groove 120 is provided on the inner wall of the side plate 100. The outer wall of the support frame 341 extends through the slide groove 120 to the bottom of the conveyor belt 210. The clamping assembly includes a base plate 300, which is fixedly installed on the inner wall of the two side plates 100 by bolts. A bearing seat 320 is installed on the top of the base plate 300. Two bearing seats 320 are symmetrically arranged on the left and right sides, and there is a passage between the two bearing seats 320. The positive and negative threaded screws 330 are rotatably connected via bearings. The outer walls of the positive and negative threaded screws 330 on both sides are threadedly connected to the inner walls of the slide block 340. The servo motor 360 is fixedly installed on the top outer wall of the base plate 300. The outer wall of the output shaft of the servo motor 360 is connected to the outer wall of the positive and negative threaded screws 330 through gear 361 meshing. Limiting ribs 310 are fixedly connected on the outer walls of both sides of the base plate 300. The outer wall of the slide block 340 is slidably limited by the inner walls of the two limiting ribs 310.

[0029] The specific application scenario of this embodiment is as follows: by turning on the servo motor 360, the servo motor 360 drives the positive and negative threaded rods 330 to rotate, which causes the positive and negative threaded rods 330 to drive the two left and right slides 340 to move towards each other, thereby causing the two slides 340 to push the two clamping plates 350 to move towards each other, and clamping and fixing the outer walls of the left and right sides of the bare plate of the carrier.

[0030] Example 4: Figure 3 and Figure 4 The clamping plate 350 has a groove 351 at the bottom of the side away from the side plate 100. The groove 351 is slidably connected to the top outer wall of the first sink 220. The bottom outer wall of the clamping plate 350 is slidably connected to the inner wall of the second sink 230. The inner wall of the clamping plate 350 has a slot 352, which is clamped to the side wall of the bare plate of the vehicle.

[0031] The specific application scenario of this embodiment is as follows: By setting clamping plates 350 to clamp and fix the outer walls of the left and right sides of the bare plate, the bare plate can be positioned during flying probe testing, improving the stability of the structure during flying probe testing and preventing the bare plate from moving. By setting groove 351 to slide and connect with the top outer wall of the first sink 220, the bottom outer wall of the slot 352 is flush with the surface of the conveyor belt 210, which facilitates the stable clamping of the bare plate on the top of the conveyor belt 210 and improves the stability of clamping the bare plate.

[0032] The working principle of this utility model is as follows: When used by those skilled in the art, the bare plate to be tested is placed on top of two conveyor belts 210, so that the left and right sides of the bare plate overlap the first sink 220 on the top of the conveyor belts 210. By turning on the servo motor to drive the conveyor rollers 200 and the conveyor belts 210 to rotate, the bare plate is transported to the underside of the flying needle type bare plate testing device (not shown in the figure). Then, by turning on the servo motor 360, the servo motor 360 drives the positive and negative threaded screws 330 to rotate, so that the positive and negative threaded screws 330 drive the two left and right slides 340 to move towards each other, thereby causing the two slides 340 to push the two clamping plates 350 respectively. The device moves in the direction of movement, clamping and fixing the outer walls of the left and right sides of the bare vehicle plate. Then, the electronic components on the surface of the bare vehicle plate are tested by activating the flying probe type bare vehicle plate testing device. After the test is completed, the servo motor 360 drives the forward and reverse threaded screws 330 to rotate in the opposite direction, causing the two slides 340 and clamping plates 350 to move in the opposite direction, so that the bare vehicle plate is separated from the clamping plates 350. Then, the servo motor is activated again to drive the conveyor rollers 200 and the conveyor belt 210 to rotate, moving the tested bare vehicle plate out of the flying probe type bare vehicle plate testing device. The next bare vehicle plate to be tested is then moved to the flying probe type bare vehicle plate testing device for contact testing.

[0033] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
