Universal edge strip for preventing plate edge from clamping film in automobile circuit board processing

Abstract

A universal edge strip for preventing a board edge from clamping a film in automobile circuit board processing comprises an edge strip A and an edge strip B. The edge strip A and the edge strip B are both of a long-strip-shaped structure, the two ends of the edge strip A protrude and the middle of the edge strip A is concave downwards, and the two ends of the edge strip B protrude and the middle of the edge strip B is concave downwards. The ball edge strip A and the edge strip B are arranged and matched with each other, the edge strips can be stretched and shortened by controlling opening and closing of the ball head assembly, and meanwhile under the emergency condition, due to the fact that a ball head of the ball head assembly is of a round structure, the edge strips can be stretched and shortened. And during extension, the extension of the edge strip can be realized without controlling the ejector rod only by increasing the strength, and the ejector rod can be controlled more smoothly.

The patent's beneficial effects mention that the device can be adapted to different PCB sizes. As can be seen from the accompanying drawings, the patent requires adjustment by screwing bolts, which are large in size and the screwing process is time-consuming and labor-intensive.

[0004] Based on this, in order to facilitate the edge strips to adapt to the sizes of different PCB boards, this design proposes a universal edge strip for automotive circuit board processing to prevent board edge clamping film. Utility Model Content

[0007] Preferably, the edge strip A includes: a strip plate A, a clamping strip, a top rod, a telescopic rod, and a ball head assembly. The cross-sectional structure of the strip plate A is a "concave"-shaped structure. The clamping strips are fixed to the protrusions at both ends of the strip plate A. The front end of the strip plate A is installed with a ball head assembly. The right side of the ball head assembly is installed with a telescopic rod. The top of the telescopic rod is installed with a top rod, and the front end of the top rod is provided with a slope.

[0012] 1. By providing the spherical edge strip A and the edge strip B, and through their mutual cooperation, the elongation and shortening of the edge strip can be realized by controlling the opening and closing of the spherical head assembly.

DETAILED DESCRIPTION OF THE INVENTION <(

[0019] The present invention will be further clearly and completely described below with reference to the accompanying drawings of the specification, but the protection scope of the present invention is not limited thereto.

[0020] According to Figure 1 and Figure 3 as shown, a universal edge strip for preventing film clamping at the edge of an automotive circuit board during processing includes: an edge strip A 1 and an edge strip B 2. The structures of the edge strip A 1 and the edge strip B 2 are both long strip shapes. Among them, both ends of the edge strip A 1 protrude and the middle is concave, and both ends of the edge strip B 2 protrude and the middle is concave.

[0021] According to Figure 2As shown, specifically, the side strip A1 includes: a strip plate A10, a clamping strip 11, a top rod 12, a telescopic rod 13, and a ball head assembly 14. The cross-sectional structure of the strip plate A10 is a "concave" shape. Clamping strips 11 are fixed at the raised parts at both ends of the strip plate A10. A ball head assembly 14 is installed at the front end of the strip plate A10. A telescopic rod 13 is installed on the right side of the ball head assembly 14, and the telescopic rod 13 can automatically pop up. A top rod 12 is installed at the top of the telescopic rod 13. A slope is provided at the front end of the top rod 12, and the slope is provided to enable the top rod 12 to smoothly push against the pressure rod 145, preventing the device from getting stuck.

[0022] According to Figure 5 As shown, specifically, the ball head assembly 14 includes: a ball head 141, a support rod 142, a front rod 143, a rotating shaft 144, and a pressure rod 145. The top of the ball head 141 is flat. A spring 15 is connected to the top of the ball head 141. A front rod 143 is fixed on the right side of the ball head 141. A rotating shaft 144 is installed on the right side of the front rod 143. A support rod 142 is installed on the upper part of the rotating shaft 144, and the other end of the support rod 142 is fixed on the strip plate A10. A pressure rod 145 is installed on the right side of the rotating shaft 144.

[0023] According to Figure 4 As shown, specifically, the side strip B2 includes: a strip plate B21, a groove 22, and a clamping block 23. The cross-sectional structure of the strip plate B21 is a "concave" shape. Grooves 22 are provided at the raised parts at both ends of the strip plate B21. A clamping block 23 is provided in the middle of the strip plate B21.

[0024] According to Figure 5 As shown, specifically, the structure of the clamping block 23 is a water droplet shape, and the clamping blocks 23 are evenly distributed in the middle position of the strip plate B21.

[0025] Working principle: When performing electroplating work, when the size of the electroplated circuit board is too large, the top rod 12 can be pressed as shown in Figure 2 As shown, when the top rod 12 is pressed down, the telescopic rod 13 will be compressed. At this time, the top rod 12 will push against the pressure rod 145 as shown in Figure 5 As shown, as the top rod 12 continuously extends, the pressure rod 145 drives the rotating shaft 144 to rotate clockwise downward, and the front rod 143 will also rotate clockwise. At this time, the ball head 141 will lift up and compress the spring 15, and the strip plate A10 and the strip plate B21 can move relative to each other, realizing the change in the length of the side strip;

[0026] Since the structure of the clamping block 23 is water droplet-shaped and the ball head structure is circular, in the case of an abnormal top rod, by applying a greater force, the relative movement between the strip plate A10 and the strip plate B21 can also be realized, improving the service life of the side strip and reducing the failure rate of the side strip.
