Description

Technical Field

[0001] This utility model relates to the field of PCB board manufacturing technology, specifically to a PCB board bending pin shaping device. Background Technology

[0002] PCB stands for Printed Circuit Board. Before the advent of printed circuit boards, electronic components were interconnected by direct wire connections to form complete circuits. In modern times, circuit boards exist primarily as effective experimental tools, while printed circuit boards have become indispensable in the electronics industry.

[0003] Existing technologies, such as the PCB board bending pin shaping device disclosed in patent (publication number: CNC223182422 U), can achieve the following by setting a shaping component: when the pins are inserted into the gap between the toothed plates, a precise alignment process is not required, making the operation simple enough, and the arrangement of multiple pins can be quickly determined after the insertion is completed. In this application, after the pins are bent, they are located in the gap between two adjacent sets of toothed plates. The bent pins need to be manually removed one by one from the gap, which takes a certain amount of time. At the same time, the device needs to stop and wait for a certain period of time before the next bending of the pins can be performed, which indirectly reduces the work efficiency of bending pins. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a PCB board bending pin shaping device, which can improve the efficiency of bending pin rows to meet the diverse bending needs of pin rows.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a PCB board bending pin shaping device, comprising a frame, wherein multiple sets of positioning grids are arranged along the width direction of the frame, the multiple sets of positioning grids are equidistantly distributed and capable of supporting the pin row, the top of the frame is slidably provided with positioning grids capable of squeezing and bending the pin row, and the top of the frame is provided with an arc edge strip near the front surface. The positioning grid assembly includes multiple sets of grid plates fixed to the inner walls of the front and rear of the frame. Each set of grid plates has a support strip fixed on one side that is close to each other. The two sets of support strips form a pin row placement area. Each set of grid plates has a clearance groove on both sides at the end of the support strip. The inner wall of the frame that fits against the end face of the support strip has a storage groove. The storage groove has a driven plate that can move towards the center of the frame with the bending strip.

[0006] According to some embodiments of the present invention, a track frame is fixed at the top of the frame near the two side walls, a T-block that slides within the track frame is fixed at the bottom of the bent strip, and an abutment strip that fits against the top of the positioning grid group is fixed at the bottom of the bent strip, with the abutment strip positioned between the two sets of T-blocks.

[0007] According to some embodiments of this utility model, the two ends of the arc edge strip are fixed to the top of the frame with screws, and the arc edge strip has an arc edge at the external corner position in the length direction on both sides, and the two sets of arc edges have different angles.

[0008] According to some embodiments of the present invention, the bottom of the bending strip is provided with two sets of trapezoidal blocks. The trapezoidal blocks are located on the side of the abutment strip close to the driven plate. The side wall of the trapezoidal blocks is fixed with a constraint rod that slides on the inner wall of the frame. The outer wall of the driven plate is fixed with a card seat at the position corresponding to the trapezoidal blocks.

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] The embodiments of this utility model will be described below based on its overall structure.

[0017] A PCB board bending pin shaping device, such as Figures 1 to 6 As shown, the frame includes a frame 100, and multiple sets of positioning grids 130 are provided inside the frame 100 along its width direction. The multiple sets of positioning grids 130 are equidistantly distributed and can support the needle row. The top of the frame 100 is slidably provided with positioning grids 130 that can compress and bend the needle row. The top of the frame 100 is provided with an arc edge strip 160 near the front surface. The positioning grid assembly 130 includes multiple grid plates 133 fixed to the inner walls of the front and rear of the frame 100. Each pair of adjacent grid plates 133 has a support strip 132 fixed on one side that is close to each other. The two pairs of support strips 132 form a pin rack placement area 131. Each grid plate 133 has a clearance groove 134 on both sides at the end of the support strip 132. The inner wall of the frame 100 that fits against the end face of the support strip 132 has a storage groove 104. The storage groove 104 has a driven plate strip 150 that can move towards the center of the frame 100 with the bending strip 140.

[0018] It is worth mentioning that, as shown in the instruction manual... Figure 1 and Figure 2As shown, the front surface of the frame 100 has a pre-reserved discharge port 110, and a guide plate 120 fixed to the inner wall of the frame 100 is provided inside the discharge port 110. The guide plate 120 is set in an inclined position. The top of the trapezoidal block 144 is provided with a blind hole, and the positioning rod 145 extends into the blind hole and is fixed with a spring 146. As per the instruction manual Figure 4 As shown, one end of the guide groove 101 is an inclined area 102, and the other end is provided with a clearance area 103; When the constraint rod 143 moves, the inclined area 102 gradually rises, which in turn drives the trapezoidal block 144 to rise linearly along the axis of the positioning rod 145, thereby engaging with the card seat 151. When the trapezoidal block 144 is about to engage with the card seat 151, the constraint rod 143 can rise in the clearance area 103 to achieve the purpose of engaging the trapezoidal block 144 with the card seat 151. When the guide groove 101 of the constraint rod 143 moves in the horizontal area, the spring 146 is in the normal state (not compressed or stretched). A track frame 142 is fixed at the top of the frame 100 near the two side walls. A T-block that slides within the track frame 142 is fixed at the bottom of the bent strip 140. An abutment strip 141 that fits against the top of the positioning grid group 130 is fixed at the bottom of the bent strip 140. The abutment strip 141 is located between the two T-blocks.

[0019] Two sets of trapezoidal blocks 144 are provided at the bottom of the bending strip 140. The trapezoidal blocks 144 are located on the side of the abutment strip 141 close to the driven strip 150. The side wall of the trapezoidal blocks 144 is fixed with a constraint rod 143 that slides on the inner wall of the frame 100. The outer wall of the driven strip 150 is fixed with a card seat 151 at the position corresponding to the trapezoidal blocks 144.

[0020] The top of the trapezoidal block 144 is provided with a positioning rod 145 connected to the bottom of the bending strip 140, and a guide groove 101 is provided at the position where the inner wall of the frame 100 contacts the constraint rod 143.

[0021] The outer wall of the card holder 151 is provided with a telescopic rod 152 that abuts against the inner wall of the frame 100 at the position below the trapezoidal card block 144. The outer wall of the telescopic rod 152 is provided with a clamp connected to the frame 100.

[0022] Place the needle array to be processed in the needle array placement area 131, ensuring that the bottom of the needle array is on the support strip 132. Operate the bending strip 140 to slide along the track frame 142. The T-block moves smoothly within the track frame 142, driving the bending strip 140 to advance towards the needle array. At this time, the abutment strip 141 slides against the top of the positioning grid group 130, the constraint rod 143 moves along the guide groove 101, and the abutment strip 141 presses tightly against one side of the needle array to fix the needle array. The bending strip 140 will squeeze the needle body of the needle array to bend to one side, and cooperate with the arc edge of the arc edge strip 160 to bend the needle body on the needle array into shape. At the same time, the trapezoidal locking block 144 and the locking seat 151 are engaged, and then the bending strip 140 is pulled to restore its original shape. This can pull the driven strip 150 to move towards the middle of the frame 100. The driven strip 150 slides out from the storage slot 104 and moves linearly under the constraint of the two sets of telescopic rods 152 (the telescopic rods 152 are equipped with a return spring to provide power for the subsequent restoration of the driven strip 150). This pushes the bent needle pack away from the needle pack placement area 131 and slides down through the clearance slot 134. Finally, the needle pack, which has been bent for a long time, automatically slides out of the frame 100 along the inclined surface of the guide plate 120, completing the shaping process.

[0023] Please refer to this carefully. Figure 1 and Figure 2 The two ends of the arc edge strip 160 are fixed to the top of the frame 100 with screws. The arc edge strip 160 has arc edges at the external corners on both sides along its length, and the two sets of arc edges have different angles. The 160mm curved edge strip can be adjusted and replaced according to the required bending radius of the needle bar, thus satisfying the bending and shaping needs of various needle bars.

[0024] Please refer to this carefully. Figure 1 Ear plates are welded to the left and right outer sides of the frame 100, and the ear plates are fixed to the external support platform with bolts.

[0025] The bolts are passed through the holes in the ear plate and rotated to fix it to the external support platform, so as to facilitate the stable bending of the pin array.
