Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board manufacturing technology, and specifically to an inspection bracket for circuit board manufacturing. Background Technology
[0002] Printed circuit boards (PCBs), also known as circuit boards, are the core carriers for electronic components, designed, manufactured, and assembled. Their primary function is to miniaturize and visualize circuit layouts, and they are widely used in electronic equipment production and layout optimization. During PCB production, testing is required. An inspection stand is a device used to fix and support PCBs for testing purposes.
[0003] Currently, traditional testing brackets can only accommodate circuit boards of specific sizes. For circuit boards of different sizes and thicknesses, different brackets need to be replaced, which increases the complexity and cost of operation. Furthermore, when installing circuit boards on testing brackets, the lack of support at the bottom of the circuit boards requires manual support until the circuit boards are fixed in place, which is very inconvenient. Utility Model Content
[0004] The purpose of this invention is to provide an inspection bracket for circuit board production, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an inspection bracket for circuit board production, comprising:
[0006] A support plate, wherein a hollow support column is fixed to the upper middle part of the support plate, a bearing plate is fixed to the upper side of the hollow support column, and side plates are fixed to the upper front, rear, left and right edges of the support plate.
[0007] The front and rear limiting assembly includes two first screws, which are symmetrically arranged on the front and rear sides of the hollow support column. A first movable seat is sleeved on the first screw by a nut, and a first pressing block is provided on the upper side of the first movable seat.
[0008] The left and right limiting assembly includes two second screws, which are symmetrically arranged on the left and right sides of the hollow support column. A second movable seat is sleeved on the second screw by a nut, and a second pressing block is provided on the upper side of the second movable seat.
[0009] A lifting assembly is installed at the bottom of a support plate.
[0010] Furthermore, the ends of the two first screws that are close to each other extend into the hollow support column, the ends of the two first screws that are close to each other are connected, and the ends of the two first screws that are far apart from each other rotate through the corresponding side plates and are connected to the first rotating handles. When one of the first screws is rotated, the other first screw will be rotated simultaneously.
[0011] Furthermore, a first limiting rod is provided below the first screw, and the two ends of the first limiting rod are respectively connected to the hollow support column and the side plate. The lower part of the first movable seat is slidably sleeved on the first limiting rod, which ensures the smooth movement of the first movable seat and improves the accuracy of operation.
[0012] Furthermore, a first rubber pad is provided on the side of the first extrusion block near the support plate, and a first connecting block is connected between the first extrusion block and the first movable seat. The lower side of the first extrusion block is lower than the lower side of the support plate, and the upper side of the first extrusion block is higher than the upper side of the support plate. The first rubber pad can protect the surface of the circuit board from being scratched by the extrusion block. The height design of the first extrusion block enables it to effectively extrude and limit the circuit board.
[0013] Furthermore, the two second screws extend into the hollow support column at their close-to-each ends, and are connected at their close-to-each ends. The two second screws also rotate through the corresponding side plates and are connected to a second rotating handle. The height of the second screws is lower than that of the first screw, so that there is no interference between the left and right limiting components and the front and rear limiting components. At the same time, rotating one of the second screws will synchronously drive the other second screw to rotate.
[0014] Furthermore, a second limiting rod is provided below the second screw. The two ends of the second limiting rod are respectively connected to the hollow support column and the side plate. The lower part of the second movable seat is slidably sleeved on the second limiting rod, which ensures the smooth movement of the second movable seat and improves the accuracy of operation.
[0015] Furthermore, a second rubber pad is provided on the side of the second extrusion block near the support plate, and a second connecting block is connected between the second extrusion block and the second movable seat. The lower side of the second extrusion block is lower than the lower side of the support plate, and the upper side of the second extrusion block is higher than the upper side of the support plate. The second rubber pad can protect the surface of the circuit board from being scratched by the extrusion block. The height design of the second extrusion block enables it to effectively extrude and limit the circuit board.
[0016] Furthermore, the lifting assembly includes a base plate, a sleeve, and a support column. The sleeve is fixed to the upper middle part of the base plate, and the support column is slidably sleeved inside the sleeve. The upper end of the support column extends out of the sleeve and connects to the lower middle part of the support plate. A locking knob is threadedly nested on the upper outer side of the sleeve. The tail end of the locking knob extends into the sleeve and abuts against the side wall of the support column. By loosening the locking knob, the locking of the support column is released, allowing the support column to move up and down inside the sleeve, thereby achieving the adjustment of the overall height to adapt to different working heights and requirements. Tightening the locking knob locks the column in place.
[0017] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0018] 1. By setting up a carrier plate, front and rear limit components and left and right limit components, the circuit board to be tested is placed on the carrier plate. The front and rear limit components limit and fix the front and rear sides of the circuit board, and the left and right limit components limit and fix the left and right sides of the circuit board. This can effectively limit and fix the circuit board, ensuring the stability and accuracy of the inspection process. At the same time, it can be applied to circuit boards of different sizes, increasing its versatility and flexibility.
[0019] 2. The overall height of this inspection stand can be adjusted by the lifting component to meet the inspection needs at different heights. Attached Figure Description

[0032] The two first screws 5 extend into the hollow support column 2 at their close ends and are connected at their close ends. The two first screws 5 also extend into the hollow support column 2 at their far ends and are connected to the first rotating handle 8 by passing through the corresponding side plate 4 at their far ends. When one of the first screws 5 is rotated, the other first screw 5 will be rotated simultaneously.
[0033] A first limiting rod 9 is provided below the first screw 5. The two ends of the first limiting rod 9 are connected to the hollow support column 2 and the side plate 4 respectively. The lower part of the first moving seat 6 is slidably sleeved on the first limiting rod 9, which ensures the smooth movement of the first moving seat 6 and improves the accuracy of operation.
[0034] The first extrusion block 7 is provided with a first rubber pad on the side near the support plate 3. A first connecting block 10 is connected between the first extrusion block 7 and the first movable seat 6. The lower side of the first extrusion block 7 is lower than the lower side of the support plate 3, and the upper side of the first extrusion block 7 is higher than the upper side of the support plate 3. The first rubber pad can protect the circuit board surface from being scratched by the extrusion block. The height design of the first extrusion block 7 enables it to effectively extrude and limit the circuit board.
[0035] The two second screws 11 extend into the hollow support column 2 at their close ends. The two second screws 11 are connected at their close ends. The two second screws 11 are connected to the corresponding side plate 4 at their far ends. The second screw 11 is at a lower height than the first screw 5, so that there is no interference between the left and right limiting components and the front and rear limiting components. When one of the second screws 11 is rotated, the other second screw 11 will be rotated synchronously.
[0036] A second limiting rod 15 is provided below the second screw 11. The two ends of the second limiting rod 15 are connected to the hollow support column 2 and the side plate 4 respectively. The lower part of the second moving seat 12 is slidably sleeved on the second limiting rod 15, which ensures the smooth movement of the second moving seat 12 and improves the accuracy of operation.
[0037] The second extrusion block 13 is provided with a second rubber pad on the side near the support plate 3. A second connecting block 16 is connected between the second extrusion block 13 and the second movable seat 12. The lower side of the second extrusion block 13 is lower than the lower side of the support plate 3, and the upper side of the second extrusion block 13 is higher than the upper side of the support plate 3. The second rubber pad can protect the circuit board surface from being scratched by the extrusion block. The height design of the second extrusion block 13 enables it to effectively extrude and limit the circuit board.
[0038] In this invention, the circuit board to be inspected is placed on the support plate 3. Then, rotating any one of the first rotating handles 8 on the front and rear limiting components can drive the two first screws 5 to rotate synchronously, causing the first moving seats 6 on the two first screws 5 to move closer to each other. This allows the two first pressing blocks 7 to approach the circuit board and press and limit the front and rear sides of the circuit board. Then, rotating any one of the second rotating handles 14 on the left and right limiting components can drive the two second screws 11 to rotate synchronously, causing the second moving seats 12 on the two second screws 11 to move closer to each other. This allows the two second pressing blocks 13 to approach the circuit board and press and limit the left and right sides of the circuit board. The operation is simple and convenient, and can effectively limit and fix the circuit board, ensuring the stability and accuracy during the inspection process. At the same time, it can be applied to circuit boards of different sizes, increasing its versatility and flexibility.
[0039] like Figure 2 As shown, the lifting assembly is installed at the bottom of the support plate 1. The lifting assembly includes a base plate 17, a sleeve 18, and a support column 19. The sleeve 18 is fixed to the upper middle part of the base plate 17. The support column 19 is slidably sleeved inside the sleeve 18. The upper end of the support column 19 extends out of the sleeve 18 and connects to the lower middle part of the support plate 1. A locking knob 20 is threadedly nested on the upper outer side of the sleeve 18. The tail end of the locking knob 20 extends into the sleeve 18 and abuts against the side wall of the support column 19.
[0040] In this utility model, when it is necessary to adjust the height of the circuit board, turn the locking knob 20 to release the lock on the support column 19, so that the support column 19 can move up and down within the sleeve 18, thereby realizing the adjustment of the overall height to adapt to different working heights and needs. Turn the locking knob 20 to lock it.
[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
