Description

Technical Field

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

[0002] Circuit boards, also known as PCBs, aluminum-based boards, high-frequency boards, ultra-thin circuit boards, printed circuit boards, etc., are mainly composed of pads, vias, mounting holes, wires, components, connectors, fillers, and electrical boundaries. Common board layer structures include single-layer boards, double-layer boards, and multi-layer boards. In the process of circuit board production, a clamping device is often needed to hold the circuit board. In the current technology, the fixed circuit board cannot be slidably adjusted, which limits the observation and inspection of the circuit board and makes it impossible to adjust.

[0003] For example, the authorized patent document CN202322012163.9 discloses a circuit board positioning support fixture, which relates to the field of support device technology. It includes a horizontally arranged guide rail, with supports sliding side-by-side on the guide rail. Clamping seats with horizontally aligned axes are rotatably mounted on opposite end faces of the supports. The clamping seats are also slidably mounted horizontally via adaptive clamping components. The height of the two clamping seats is vertically adjustable. Single-board clamping grooves are longitudinally formed on the opposite end faces of the two clamping seats, and several multi-board clamping grooves are parallelly formed between the opposite sidewalls of the clamping seats. This invention solves the problem that traditional devices are limited by their support structure, easily obscuring a large area of ​​the circuit board. This necessitates repositioning and fixing the circuit board when it needs to be re-welded, affecting the circuit board welding efficiency.

[0004] The aforementioned patent has limitations, namely that the fixed circuit board cannot be slidably adjusted. Therefore, we need to provide a clamping device for circuit board processing with adjustment function. Utility Model Content

[0005] The purpose of this invention is to provide a clamping device for circuit board processing with adjustable function. By placing the circuit board on a placement frame, a motor is started to rotate a threaded rod. The surface of the threaded rod is threaded into the inside of a lifting plate, causing the lifting plate to move downwards. The descending lifting plate drags the push plates on both sides, causing them to swing and pull the two clamping plates on both sides of the lifting plate closer together, thus limiting and fixing the circuit board. Rotating the handwheel rotates an adjusting rod, which is threaded into a magnifying glass assembly, allowing for height adjustment of the magnifying glass assembly. This facilitates observation and inspection of the fixed circuit board surface. Simultaneously, a movable swing frame allows the swaying of the swing frame to cause the balls inside the ball cage to roll on the top of the slide table, adjusting the observation position more flexibly. When limiting the swing frame, four cylinders are activated, all of which are synchronous cylinders. These cylinders push rubber blocks to squeeze the balls inside the ball cage, thus limiting the placement frame and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for circuit board processing with an adjustable function, comprising: Display frame; and the four slots formed at the top of the placement frame; The placement frame is equipped with clamps for fixing the circuit board. The bottom of the placement frame is provided with a sliding platform, and the bottom of the placement frame is equipped with a sliding component for adjusting the sliding of the placement frame. The sliding component includes four cylinders fixedly installed at the bottom of the placement frame. The bottom of each of the four cylinders is connected to a ball cage. Rolling balls are rolled inside each of the four ball cages, and the cylinders are provided with abutment members for limiting the movement of the rolling balls.

[0007] Preferably, the abutting element includes a cylinder disposed inside the cylinder, the top of the cylinder being fixedly installed at the bottom of the placement frame, and a rubber block for abutting the limiting ball being fixedly installed at the lower end of the cylinder.

The top of the clamping plate passes through the top of the slot and extends therefrom. A driving member for moving the push rod is installed inside the placement frame, and a sliding plate that slides inside the clamping plate is fixedly installed inside each of the four slots.

[0009] Preferably, the driving component includes a threaded rod rotatably mounted within the placement frame, and a motor is mounted on the lower end of the threaded rod.

[0010] Preferably, two support rods are fixedly installed inside the placement frame, and the surfaces of the two support rods are slidably installed inside the lifting plate.

[0011] Preferably, an adjustment frame is rotatably mounted inside the slide, an adjustment rod is rotatably mounted inside the adjustment frame, a magnifying glass assembly is threaded onto the surface of the adjustment rod, and a handwheel is mounted on the top of the adjustment rod, which passes through the top of the adjustment frame.

In this embodiment, the circuit board is placed on the placement frame 1, and the motor 302 is started to drive the threaded rod 301 to rotate. The surface of the threaded rod 301 is threadedly installed with the inside of the lifting plate 31, thereby driving the lifting plate 31 to move down. The lowering of the lifting plate 31 drags the push plates 32 on both sides to swing, thereby pulling the two clamping plates 33 on both sides of the lifting plate 31 closer together, thus limiting and fixing the circuit board. By rotating the handwheel, the adjusting rod 8 is driven to rotate. The adjusting rod 8 is threadedly installed with the magnifying glass assembly 9, thereby driving the height adjustment of the magnifying glass assembly 9, which facilitates the observation and inspection of the fixed circuit board surface. At the same time, the swing frame can be moved. The swing frame can cause the rolling ball 53 in the ball cage 52 to roll on the top of the slide table 4, adjusting the observation position more flexibly. When it is necessary to limit the swing frame, four cylinders 501 are activated. The four cylinders 501 are synchronous cylinders 501. The cylinders 501 push the rubber block 502 to squeeze the rolling ball 53 in the ball cage 52, thereby achieving the purpose of limiting the placement frame 1.

[0019] The clamping component 3 includes a lifting plate 31 disposed inside the placement frame 1. Two push plates 32 are hinged to both sides of the lifting plate 31. A clamping plate 33 is hinged to the top of each of the two push plates 32. The top of the clamping plate 33 passes through the top of the slot 2 and extends thereto. A drive component 30 for moving the push rod is installed inside the placement frame 1. A sliding plate 34 that slides inside the clamping plate 33 is fixedly installed inside each of the four slots 2. Specifically, the circuit board is placed on the placement frame 1, and the motor 302 is started to drive the threaded rod 301 to rotate. The surface of the threaded rod 301 is threaded with the inside of the lifting plate 31, thereby driving the lifting plate 31 to move down. The lowering of the lifting plate 31 drags the push plates 32 on both sides to swing, thereby pulling the two clamping plates 33 on both sides of the lifting plate 31 closer together, thus playing a role in limiting and fixing the circuit board.

[0020] The driving component 30 includes a threaded rod 301 rotatably mounted in the placement frame 1, and a motor 302 is mounted on the lower end of the threaded rod 301; Furthermore, the starter motor 302 drives the threaded rod 301 to rotate, and the surface of the threaded rod 301 is threaded with the inside of the lifting plate 31, thereby driving the lifting plate 31 to move down. The lifting plate 31 descends and drags the push plates 32 on both sides to swing.

[0021] Two support rods 6 are fixedly installed inside the placement frame 1, and the surfaces of the two support rods 6 are slidably installed inside the lifting plate 31. The lifting plate 31 is moved by the driving component 30 and slides on the two support rods 6, thereby enhancing the stability of the height adjustment of the lifting plate 31.

[0022] An adjustment frame 7 is rotatably mounted inside the slide table 4. An adjustment rod 8 is rotatably mounted inside the adjustment frame 7. A magnifying glass assembly 9 is threaded onto the surface of the adjustment rod 8. The top of the adjustment rod 8 passes through the top of the adjustment frame 7 and is equipped with a handwheel. The adjustment rod 8 is rotated by turning the handwheel. The adjustment rod 8 is threadedly installed with the magnifying glass assembly 9, thereby adjusting the height of the magnifying glass assembly 9 to facilitate observation and inspection of the fixed circuit board surface.

[0023] In order to provide better lighting for the circuit board at the top of the placement frame 1 and facilitate the observation and inspection of the circuit board, a lighting plate 10 is fixedly installed on the front of the adjustment frame 7.

[0024] This device places the circuit board on the placement frame 1. The motor 302 is started, driving the threaded rod 301 to rotate. The threaded rod 301 is threadedly installed inside the lifting plate 31, causing the lifting plate 31 to move downwards. The descending lifting plate 31 drags the push plates 32 on both sides, causing them to swing and pull the two clamping plates 33 on both sides of the lifting plate 31 closer together, thus limiting and fixing the circuit board. The handwheel is rotated, driving the adjusting rod 8 to rotate. The adjusting rod 8 is threadedly installed with the magnifying glass assembly 9, allowing for height adjustment of the magnifying glass assembly 9, facilitating observation and inspection of the fixed circuit board surface. Simultaneously, the swing frame can be moved. The swing frame's movement causes the rolling ball 53 inside the ball cage 52 to roll on the top of the slide table 4, adjusting the observation position more flexibly. When the swing frame needs to be limited, four cylinders 501 are activated. These four cylinders 501 are synchronous cylinders. The cylinders 501 push the rubber block 502 to squeeze the rolling ball 53 inside the ball cage 52, thus limiting the placement frame 1.
