Description

Technical Field

[0001] The utility model relates to a clamping device, in particular to a clamping device suitable for a narrow PCB. Background Art

[0002] At present, in the PCB manufacturing process, according to the requirements of different customers, the PCB boards produced have different shapes, some with board edges (broken edges), some without board edges or narrow edges. When processing and testing are required, suitable jigs or carriers are needed to position the PCB.

[0003] However, for existing narrow-edge PCBs, conventional limit blocks will pinch the board edges and block the solder joints or contacts on the side of the PCB, causing detection anomalies. For this reason, a support sheet is often needed to assist in applying pressure. However, this type of structure has high requirements for limit accuracy. If there is an assembly tolerance, it is easy to pinch other components on the PCB.

[0004] At the same time, the existing structure occupies a large splint area, and at least 6*3mm of space needs to be reserved. For this reason, it is often necessary to specially customize the corresponding bracket, resulting in an increase in the cost of use.

[0005] In view of the above-mentioned defects, the designers of the present invention have actively conducted research and innovation in order to create a clamping device suitable for narrow-board PCBs, making it more valuable for industrial use. Utility Model Content

[0008] Furthermore, in the above-mentioned clamping device suitable for narrow-board PCB, the bottom bearing block is located in the middle of the limiting convex strip to form a clamping area, and a silicone pad is arranged in the clamping area.

[0009] Furthermore, in the above-mentioned clamping device suitable for narrow-board PCB, the edge of the supporting convex strip is provided with a circular arc chamfer.

[0028] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] like Figures 1 to 3 The clamping device suitable for narrow board PCB includes a bottom bearing block 1, and its uniqueness lies in that an upper clamping block 2 is movably arranged on the bottom bearing block 1. In this way, through the cooperation of the bottom bearing block 1 and the upper clamping block 2, the side of the narrow board PCB 10 can be clamped and positioned with the cooperation of an external driving device. Considering that the edge of the narrow board PCB 10 is narrow and easy to get loose during the clamping period, the utility model has a supporting convex strip 3 extending inward from the bottom bearing block 1. In this way, the side bottom of the narrow board PCB 10 can be effectively supported. At the same time, the two sides of the bottom bearing block 1 have limit convex strips 4 extending upward in a mirror image. In this way, the upper clamping block 2 has a suitable lateral limit when moving up and down, ensuring that there is no lateral shift during the clamping period, avoiding the tearing of the combination. In addition, a clamping edge 5 is arranged at the position of the upper clamping block 2 facing the bottom bearing block 1. In this way, better force contact can be achieved. During implementation, the cross section of the clamping edge 5 is arc-shaped, so that the sharp corners can be prevented from causing edge clipping of the narrow PCB 10. In order to have better flexible contact, a silicone layer can be attached to the bottom of the clamping edge 5. Furthermore, in order to achieve stable and convenient connection with related drive equipment and loading brackets, a drive connection structure is provided on the upper clamping block 2, and a limit position structure is provided on the bottom bearing block 1.

[0030] In combination with a preferred embodiment of the utility model, the bottom bearing block 1 is located in the middle of the limiting convex strip 4 to form a clamping area, and a silicone pad is arranged in the clamping area. In this way, for some PCBs without board edges, the combined friction can be increased, and flexible contact can be provided to meet the requirements of lossless loading while preventing it from slipping. Similarly, for narrow board PCB10, better flexible bearing can also be achieved.

[0031] Further, the utility model is provided with an arc chamfer at the edge of the supporting convex strip 3. At the same time, an arc chamfer is provided at the edge of the limiting convex strip 4. In this way, the existence of sharp parts is avoided and the external period and the clamped PCB board will not be scratched.

[0032] In view of the actual implementation, considering the stable connection with the corresponding working end of the cylinder or electric cylinder, the drive connection structure includes a transverse threaded hole 6 set in the upper clamp block 2, which can be directly connected by screws. At the same time, in order to achieve effective back plug-in positioning during the installation of the upper clamp block 2 and avoid unnecessary shaking during operation, a limit card slot 7 is set on the back of the upper clamp block 2, and the bottom of the transverse threaded hole 6 passes through the limit card slot 7. In this way, a card block can be set at the working end of the cylinder or electric cylinder to achieve better auxiliary limiting. In addition, considering the convenience of subsequent installation and maintenance, the upper clamp block 2 is provided with a clearance slot 8 at the front end of the transverse threaded hole 6. In this way, the user can operate the tool machine screw connection more conveniently.

[0033] Further, the limiting structure adopted by the present invention is a vertical threaded hole 9. In this way, it can adapt to the bottom limiting rod of the clamping device and realize stable limiting of the bottom bearing block 1. During implementation, two vertical threaded holes 9 can be used to effectively bear the clamping stress during clamping, without skewing or causing undesirable wrinkles on the edge of the narrow board PCB 10.

[0034] The working principle of the utility model is as follows:

[0035] The external drive device drives the upper clamp block 2 to lift up, leaving a clamping area. After that, the feeding device places the narrow board PCB 10 on the clamping area corresponding to the bottom bearing block 1. Then, the external drive device drives the upper clamp block 2 to press down, just clamping the side of the narrow board PCB 10. In this way, stable transportation clamping can be achieved.

[0036] It can be seen from the above text description and the accompanying drawings that the following advantages are achieved after adopting the utility model:

[0037] 1. It can stably clamp narrow PCBs and PCBs without board edges without falling off, and has proper bottom support.

[0038] 2. The clamping edge has a certain curvature, which can achieve flexible contact and will not cause clamping damage.

[0039] 3. The overall structure is simple, can be installed with the current conventional clamping drive equipment, and is easy to use.

[0040] In addition, the indicated orientations or positional relationships described in the present invention are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or structure referred to must have a specific orientation or be operated with a specific orientation structure. Therefore, they cannot be understood as a limitation on the present invention.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
