Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically a clamping device for circuit board processing. Background Technology

[0002] Clamping devices for circuit board processing are specialized tools or mechanisms used to securely hold printed circuit boards during manufacturing or testing. Their core purpose is to prevent the circuit board from shifting, vibrating, or bending during processes such as drilling, milling, soldering, testing, and assembly, thereby ensuring processing accuracy, protecting the circuit board from physical damage, improving production efficiency, and ensuring operational safety.

[0003] A clamping and fixing device for circuit board processing disclosed in Chinese Patent Publication No. CN214757118U uses a dust cover to prevent external dust from accumulating on the circuit board and in the grooves. Simultaneously, an exhaust fan vents the equipment to prevent dust generated during circuit board processing from spreading. The exhaust fan removes the dust through the air outlet. A first pneumatic rod extends under the action of a pneumatic pump to accommodate circuit boards of different sizes. A turntable allows the angle of the mounting plate to be adjusted. A second pneumatic rod, in conjunction with a stop block, can fix the mounting plate to prevent it from shaking. However, the clamping device has certain limitations; it can only clamp the sides of the circuit board, which is not suitable for the sides of circuit boards of different specifications. Utility Model Content

[0004] The purpose of this invention is to provide a clamping device for circuit board processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for circuit board processing, including a base, a limiting groove formed at the center of the upper surface of the base, clamping mechanisms provided on the left and right sides inside the base, clamping plates provided on the left and right sides of the upper surface of the clamping mechanisms, support blocks provided on the inner sides of the two clamping plates, a turntable rotatably connected inside the limiting groove, and a positioning mechanism for fixing the position of the turntable after rotation.

[0006] A negative pressure machine is installed at the center of the turntable, and a suction cup located at the center of the upper surface of the turntable is fixed to the top of the negative pressure machine.

[0007] Preferably, the clamping mechanism includes first through slots on the left and right sides inside the base, first partitions fixedly connected to the left and right sides inside the first through slots, side plates fixedly connected to the left and right sides of the upper surface of the base, elastic ropes fixedly connected to the front and rear ends of the inner side of the side plates, a servo motor fixedly connected to the center of the bottom end inside the first through slot, a take-up shaft installed at the output shaft end of the servo motor, pull ropes fixedly connected to the left and right sides outside the take-up shaft, a first moving block fixedly connected to the outer side of the pull rope, the top end of the first moving block fixedly connected to the clamping plate, a first spring fixedly connected to the inner side of the first moving block, second through slots opened at the front and rear ends inside the clamping plate, second partitions fixedly connected to the inner sides of the two second through slots, a steering shaft rotatably connected to the inner side of the second through slots, a second spring fixedly connected to the outer side of the second partition, and a second moving block fixedly connected to the outer side of the second spring.

[0008] Preferably, the inner side of the second movable block is fixedly connected to the end of the elastic rope away from the side plate, and the inner side of the second movable block is fixedly connected to the support block.

[0009] Preferably, the positioning mechanism includes a slot opened inside the left side of the bottom of the turntable, a movable block slidably connected inside the slot, a third spring fixed to the top of the movable block, a positioning block fixed to the bottom of the movable block, and a positioning groove evenly and circumferentially opened at equal intervals inside the limiting groove.

[0010] Preferably, the positioning groove is provided in six sets of evenly spaced circumferences with the center point of the limiting groove as the axis, and one set of positioning grooves is inserted into the positioning block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This type of clamping device for circuit board processing has a servo motor installed in the base. When the servo motor is started, it drives the winding shaft to rotate. At this time, the winding shaft can pull the first moving block to move through the pull rope. The first moving block can drive the clamping plate to move inward and perform clamping and limiting work on the left and right ends of the circuit board. At the same time, when the clamping plate moves, the elastic rope on the side plate can pull the second moving block inside the clamping plate to move. At this time, the second moving block drives the support block to move, so that the support block on the clamping plate can quickly clamp the left and right sides of the front and rear ends of the circuit board, thereby performing clamping work on circuit boards of different sizes and specifications from all directions, effectively improving the overall applicability of the clamping device.

[0013] 2. This type of clamping device for circuit board processing allows for the rapid placement and lifting of circuit boards by a turntable positioned at the center of the upper surface of the base. A suction cup at the top of the turntable provides quick positioning of the circuit board. Simultaneously, a positioning mechanism is installed inside the bottom of the turntable. By engaging positioning blocks into positioning slots within the limiting grooves, the position of the turntable can be fixed. Furthermore, by engaging positioning blocks into different positioning slots within the limiting grooves, the position of the turntable and the circuit board after rotation can be quickly fixed. This facilitates rapid adjustment of the clamping angle of the circuit board and improves the overall functionality of the clamping device. Attached Figure Description

Detailed Implementation

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 As shown, the present invention has the following specific embodiment.

[0022] Example 1:

[0023] A clamping device for circuit board processing includes a base 1. A limiting groove 105 is formed at the center of the upper surface of the base 1. Clamping mechanisms 2 are arranged on the left and right sides inside the base 1. Clamping plates 3 are arranged on the left and right sides of the upper surface of the clamping mechanisms 2. Support blocks 4 are arranged on the inner sides of the two clamping plates 3. A turntable 5 is rotatably connected inside the limiting groove 105. The limiting groove 105 can provide rotation limit for the turntable 5.

[0024] A negative pressure machine is installed at the center of the turntable 5. A suction cup located at the center of the upper surface of the turntable 5 is fixed to the top of the negative pressure machine. When the negative pressure machine is started, it can generate negative pressure in the suction cup and stably perform the adsorption of the circuit board.

[0025] The clamping mechanism 2 includes first through slots 101 on the left and right sides inside the base 1. First partition plates 102 are fixedly connected to the left and right sides inside the first through slots 101. Side plates 103 are fixedly connected to the left and right sides of the upper surface of the base 1. Elastic ropes 104 are fixedly connected to the front and rear ends of the inner side of the side plates 103. A servo motor 201 is fixedly connected to the center of the bottom end inside the first through slots 101. A winding shaft 202 is installed on the output shaft end of the servo motor 201. Pull ropes 203 are fixedly connected to the left and right sides outside the winding shaft 202. A first moving block 204 is fixedly connected to the outer side of the pull rope 203. The top of the first moving block 204 is fixedly connected to the clamping plate 3. A first spring 205 is fixedly connected to the inner side of the first moving block 204. Second through slots 301 are opened at the front and rear ends inside the clamping plate 3. Second partition plates 302 are fixedly connected to the inner sides of the two second through slots 301. A steering shaft 303 is rotatably connected to the inner side of the second through slots 301. A second spring 304 is fixedly connected to the outer side of the second partition 302, and a second moving block 305 is fixedly connected to the outer side of the second spring 304. When the servo motor 201 is started, it can drive the winding shaft 202 to rotate. At this time, the winding shaft 202 pulls the pull ropes 203 on both sides to wind up. The pull ropes 203 can drive the clamping plate 3 to move through the first moving block 204. At the same time, the first moving block 204 can squeeze the first spring 205 on one side, and the clamping plate 3 moves. Then, the elastic rope 104 on the side plate 103 can pull the second moving block 305 to move. At this time, the second moving block 305 can squeeze the second spring 304 and drive the support block 4 to move, so that the support block 4 can clamp the left and right sides of the front and rear ends of the circuit board. When the servo motor 201 drives the winding shaft 202 to reset, the reaction force of the first spring 205 and the second spring 304 being squeezed can push the clamping plate 3 and the support block 4 to reset respectively.

[0026] The inner side of the second moving block 305 is fixedly connected to the end of the elastic rope 104 away from the side plate 103, and the inner side of the second moving block 305 is fixedly connected to the support block 4.

[0027] Example 2:

[0028] The difference from Embodiment 1 is that this embodiment discloses a positioning mechanism 6 for fixing the position of the turntable 5 after it rotates;

[0029] The positioning mechanism 6 includes a slot 601 inside the left side of the bottom of the turntable 5. A movable block 602 is slidably connected inside the slot 601. A third spring 603 is fixed to the top of the movable block 602, and a positioning block 604 is fixed to the bottom of the movable block 602. Positioning slots 106 are evenly spaced and circumferentially formed at the bottom of the limiting slot 105. When the positioning block 604 at the bottom of the turntable 5 is subjected to force, the movable block 602 can squeeze the third spring 603. At this time, the positioning block 604 can be retracted into the turntable 5. When the positioning block 604 is released from force, the reaction force of the squeezed third spring 603 can push the positioning block 604 to quickly reset through the movable block 602.

[0030] The positioning groove 106 is provided with six sets of evenly spaced circumferences around the center point of the limiting groove 105. One set of positioning grooves 106 is inserted into the positioning block 604. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] In this embodiment, the circuit board to be positioned is placed at the center of the top of the turntable 5. The negative pressure machine inside the turntable 5 is activated, which generates suction from the suction cups at the top of the turntable 5 and stably adsorbs the circuit board. By rotating the turntable 5, the circuit board can be rotated to a suitable angle. The servo motor 201 inside the base 1 is then activated, which drives the winding shaft 202 to rotate. The winding shaft 202 pulls the pull ropes 203 on both sides to wind up the circuit board. The pull ropes 203 can drive the clamping plate 3 to move through the first moving block 204. The clamping plate 3 can then clamp the left and right sides of the circuit board. As the clamping plate 3 moves, the elastic rope 104 on the side plate 103 can pull the second moving block 305 to move. The second moving block 305 can then compress the second spring 304 and drive the support block 4 to move, thereby allowing the support block 4 to clamp the left and right sides of the front and rear ends of the circuit board.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
