Description

Technical Field

[0001] This utility model is a PCB lamination board thickness detection device, belonging to the field of printed circuit board inspection technology. Background Technology

[0002] Printed circuit boards (PCBs), as core components of electronic devices, are widely used in various fields. With the rapid development of electronic technology, electronic products are constantly moving towards miniaturization and high performance, which places extremely stringent requirements on the manufacturing precision and quality of PCBs. The lamination process is a crucial step in PCB manufacturing, and the quality of the laminate directly affects the electrical, mechanical, and reliability of the PCB. Among these factors, board thickness accuracy is one of the important indicators for measuring the quality of the laminate. In the current market environment, consumers have increasingly higher expectations for the performance and stability of electronic products. To meet this demand, electronic equipment manufacturers are constantly pursuing higher density and more complex PCB designs, which makes the requirements for the thickness precision of laminates increasingly stringent, in order to ensure the stability of signal transmission and the overall performance of the equipment.

[0003] Therefore, developing a device for detecting the thickness of PCB laminates has significant practical implications and market value. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a PCB lamination board thickness detection device.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A PCB laminate thickness detection device includes a detection base. A detection groove is formed on one side of the top of the detection base. A positioning mechanism that mates with the PCB laminate is disposed inside the detection groove. A fixing plate is disposed on the other side of the top of the detection base. The fixing plate is provided with the detection mechanism that mates with the PCB laminate. A marking component is disposed at the end of the outer surface of the fixing plate near the detection groove. The marking component is adapted to the detection mechanism. The marking component includes a vertically formed sliding groove at the edge of the fixing plate. A sliding block with a T-shaped structure is slidably connected within the sliding groove. The end of the sliding block passes through the opening of the sliding groove to the outside of the fixing plate and is connected and fixed to the marking plate. One side of the marking plate presses against the detection mechanism, and the other side of the marking plate is adapted to a vertically set scale line. The scale line is located on the outer surface of the fixing plate and on the side of the sliding groove.

[0006] Furthermore, the positioning mechanism includes a sliding groove vertically formed on the inner walls of adjacent sides of the detection groove, a slider slidably connected in the sliding groove, a positioning frame fixed in the middle of the slider near the opening of the sliding groove, the positioning frames on both sides stacked alternately, a sliding column slidably connected between the two positioning frames, a plug-in block vertically inserted in the middle of the sliding column, and a plurality of plug-in slots that cooperate with the plug-in blocks in the inner bottom of the detection groove.

[0007] Furthermore, guide rail grooves are provided in the middle of both positioning frames, and a U-shaped groove is provided in the middle of the sliding column. The U-shaped groove is adapted to the upper and lower guide rail grooves, and the inner walls of the upper and lower sides of the U-shaped groove are respectively attached to the top outer surface of the upper positioning frame and the bottom outer surface of the lower positioning frame.

[0008] Furthermore, a through hole is provided in the middle of the sliding column, the plug block is slidably connected in the through hole, and a damping layer that cooperates with the plug block is provided on the inner wall of the through hole.

[0009] Furthermore, a positioning block is inserted into the inner wall of the detection groove and between two adjacent insertion grooves, and a positioning slot that cooperates with the positioning block is provided at the bottom center of the insertion block.

[0010] Furthermore, the detection mechanism includes several vertically opened sliding holes in the middle of the fixed plate, and a sliding member is slidably connected in the sliding hole. One end of the sliding member is connected and fixed to the detection plate through a connecting plate, and several detection plates are stacked together vertically.

[0011] The beneficial effects of this utility model are: The design of the positioning and detection mechanisms allows it to be adapted to various PCB lamination boards, and the detection work can be completed with a single push action and a single scale reading, making the operation simple and quick.

[0012] Through the design of the positioning mechanism, during use, the PCB laminating plate is placed inside the detection slot at the corner near the fixed plate and the detection plate. Then, the positioning frames on both sides are moved by manual pulling, so that the positioning frames on both sides are pressed together with the sides of the PCB laminating plate. Next, by pressing the plug on the sliding post, the plug moves downward on the sliding post. The bottom end of the plug will insert into the plug slot or positioning block in the detection slot, thereby limiting the sliding post located in the positioning frames on both sides, achieving the purpose of positioning the positioning frames on both sides.

[0013] By designing a damping layer, the friction between the sliding column and the through hole is increased, thereby improving the stability of the sliding column's movement.

[0014] By designing positioning blocks and positioning slots, the positioning frames on both sides can be locked and fixed by the snap-fit ​​of the positioning blocks and positioning slots when the position of the plug-in block does not match the position of the plug-in slot.

[0015] Through the design of the testing mechanism, after the PCB lamination board is stably confined within the testing slot, several vertically stacked testing boards are manually pushed from the right side to move horizontally to the left. During the movement, testing boards at the same height as the PCB lamination board will be stopped by the PCB lamination board and will not move, while testing boards higher than the PCB lamination board will not be affected and will move normally. After the higher testing boards have moved past, the height of the stationary testing board is the thickness of the PCB lamination board. The marking board is also firmly pressed onto the top testing board under the action of gravity, and one edge of the marking board is firmly aligned with the scale line to indicate the thickness. The staff can then read the thickness.

[0016] By setting sliding parts at different positions on the same side of several detection plates, the stability of the detection plates can be ensured while maintaining the requirement of low plate thickness, and the lateral movement of several detection plates can be unaffected.

[0017] The design of the sliding component and connecting plate ensures that the detection plate, being relatively thin and only intended to meet detection requirements without bearing weight, is lightweight. Therefore, the combined support of the sliding component and connecting plate can meet the support requirements of the detection plate.

[0018] Through the design of the marking component, after the detection plate, which is higher than the PCB lamination plate on the detection mechanism, moves, the marking plate is also steadily pressed down among several stationary detection plates under the action of gravity. The top of the top plate and one edge of the marking plate are steadily aligned with the scale line to indicate the thickness. The staff can then read the thickness. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-7This utility model provides a technical solution for a PCB lamination board thickness detection device, including a detection base 1. A detection groove 2 is formed on one side of the top of the detection base 1. A positioning mechanism that cooperates with the PCB lamination board is disposed inside the detection groove 2. A fixing plate 8 is disposed on the other side of the top of the detection base 1. The fixing plate 8 is provided with a detection mechanism that cooperates with the PCB lamination board. An marking component is disposed at the end of the outer surface of the fixing plate 8 near the detection groove 2. The marking component is adapted to the detection mechanism. The marking component includes a sliding groove vertically formed at the edge of the fixing plate 8. A sliding block 13 is slidably connected in the sliding groove. The sliding block 13 has a T-shaped structure. The end of the plate passes through the opening of the sliding groove and extends to the outside of the fixing plate 8, where it is connected and fixed to the marking plate 14. One side of the marking plate 14 is pressed against the detection mechanism, and the other side of the marking plate 14 is adapted to the vertically set scale line 15. The scale line 15 is set on the outer surface of the fixing plate 8 and located on the side of the sliding groove. Through the design of the marking component, after the detection plate 12, which is higher than the PCB bonding plate, moves on the detection mechanism, the marking plate 14 is also steadily pressed against several stationary detection plates 12 under the action of gravity. The top of the uppermost plate and one edge of the marking plate 14 are steadily connected to the scale line 15 to indicate the thickness. The operator can then take the reading.

[0024] See Figures 1-4 The positioning mechanism includes a sliding groove vertically formed on the inner walls of adjacent sides of the detection groove 2. A slider 3 is slidably connected within the sliding groove. A positioning frame 4 is fixed to the middle of the slider 3 near the opening of the sliding groove. The positioning frames 4 on both sides are stacked alternately. A sliding post 5 is slidably connected between two positioning frames 4. A plug-in block 6 is vertically inserted into the middle of the sliding post 5. Several plug-in slots 7 that cooperate with the plug-in blocks 6 are formed in the inner bottom of the detection groove 2. Through the design of the positioning mechanism, the PCB laminating board is positioned during use. Placed inside the detection slot 2 at the corner near the fixed plate 8 and the detection plate 12, the positioning frames 4 on both sides are then moved by manual pulling, causing the positioning frames 4 on both sides to be pressed together with the sides of the PCB bonding plate. Then, by pressing the insertion block 6 on the sliding post 5, the insertion block 6 is inserted and moved downward on the sliding post 5. The bottom end of the insertion block 6 will be inserted into the insertion slot 7 or the positioning block in the detection slot 2, thereby limiting the sliding post 5 located in the positioning frames 4 on both sides, achieving the purpose of positioning the positioning frames 4 on both sides.

[0025] See Figure 3Both positioning frames 4 have guide rail grooves in their middle sections, and the sliding column 5 has a U-shaped groove in its middle section. The U-shaped groove is adapted to the upper and lower guide rail grooves. The inner walls of the upper and lower sides of the U-shaped groove are respectively attached to the top outer surface of the upper positioning frame 4 and the bottom outer surface of the lower positioning frame 4. Through the design of the U-shaped groove, when the horizontal positioning frame 4 moves, the horizontal positioning frame 4 will push the U-shaped groove through the inner wall of the guide rail groove, thereby driving the sliding column 5 to move. The sliding column 5 will move along the guide rail groove on the vertical positioning frame 4.

[0026] See Figure 5 The sliding column 5 has a through hole in the middle, and the plug block 6 is slidably connected in the through hole. The inner wall of the through hole is provided with a damping layer that cooperates with the plug block 6. The design of the damping layer improves the friction between the sliding column 5 and the through hole, thereby improving the stability of the sliding column 5.

[0027] A positioning block is inserted into the inner wall of the detection groove 2 and between two adjacent insertion grooves 7. A positioning slot is provided at the bottom center of the insertion block 6 to cooperate with the positioning block. Through the design of the positioning block and the positioning slot, when the position of the insertion block 6 does not match the insertion groove 7, the positioning frame 4 on both sides can be locked and fixed by the locking and fixing of the positioning block and the positioning slot.

[0028] See Figures 5-6 The detection mechanism includes several vertically opening sliding holes 9 in the middle of the fixed plate 8. A sliding member 10 is slidably connected in the sliding holes 9. One end of the sliding member 10 is connected and fixed to the detection plate 12 through the connecting plate 11. Several detection plates 12 are stacked vertically together. Through the design of the detection mechanism, after the PCB laminate is stably restricted in the detection groove 2, several vertically stacked detection plates 12 can be manually pushed from the right side to move horizontally to the left. During the movement, the detection plates 12 at the same height as the PCB laminate will be stopped by the PCB laminate and will not move, while the detection plates 12 higher than the PCB laminate will not be affected and will move normally. After the higher detection plates 12 have moved past, the height of the stationary detection plates 12 is the thickness of the PCB laminate.

[0029] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.

[0030] In use, the PCB laminating plate is placed inside the detection slot 2 at the corner near the fixed plate 8 and the detection plate 12. Then, the positioning frames 4 on both sides are moved manually, causing them to press together with the sides of the PCB laminating plate. Next, the insertion block 6 on the sliding post 5 is pressed down, causing it to insert downwards. The bottom end of the insertion block 6 inserts into the insertion slot 7 or positioning block in the detection slot 2, thus fixing the sliding post 5 within the positioning frames 4 and positioning the two sides. After the PCB laminating plate is stably fixed in the detection slot 2, several vertically stacked detection plates 12 are manually pushed horizontally to the left from the right side. During this movement, the PCB laminating plate is positioned in a way that... The detection plate 12 at the same height as the PCB laminator will be stopped by the PCB laminator and will not move. The detection plate 12 above the PCB laminator will not be affected and will move normally. After the higher detection plate 12 moves past, the height of the stationary detection plate 12 is the thickness of the PCB laminator. The marking plate 14 is also firmly pressed on the uppermost detection plate 12 under the action of gravity. One edge of the marking plate 14 is firmly connected with the scale line 15 to indicate the thickness. The staff can then read the thickness. For subsequent PCB laminators of the same specification, the two fixed positioning frames 4 do not need to be moved or adjusted. They can be used directly. Only when detecting PCB laminators of different sizes should the above operation be repeated for adjustment.

[0031] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
