Description

Technical Field

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

[0002] A circuit board, or printed circuit board (PCB), is the core carrier that holds and connects electronic components in electronic devices. It uses an insulating substrate (such as epoxy resin) to isolate the conductive copper foil layer on the surface, guiding current to flow between components along a designed path to achieve signal transmission and functional operations (such as amplification and modulation). It is the "neural network skeleton" of electronic devices. Circuit board processing, as a core link in electronic manufacturing, involves multiple processes such as soldering, drilling, and visual inspection, placing stringent requirements on the angular flexibility, dimensional adaptability, clamping efficiency, and automation compatibility of fixtures.

[0003] However, existing technologies have significant bottlenecks: traditional fixtures are mostly designed with fixed angles, which cannot meet the needs of complex processing scenarios. For example, when soldering components on the edge of a circuit board, angle obstruction requires manual placement of wedges for assistance, resulting in poor accuracy and time-consuming adjustments. When visual inspection requires specific observation angles, the fixtures cannot be flexibly adapted, leading to a high risk of missed inspections. Furthermore, different circuit board models require customized fixtures, resulting in high costs, slow changeover times, and significant inventory pressure. Therefore, those skilled in the art have provided a circuit board processing fixture device with an adjustable rotatable angle to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a rotatable and adjustable circuit board processing fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A rotatable and adjustable circuit board processing fixture includes a base, a servo motor, a rotating seat, a first movable plate, and a second movable plate. The rotating seat is positioned above the base, and the first and second movable plates are positioned above the rotating seat. A first interlocking plate is fixedly connected to the bottom of one side of the first movable plate, and a second interlocking plate is fixedly connected to the bottom of one side of the second movable plate. The first and second interlocking plates are interlocked together. Each of the first and second movable plates has a lifting groove on one side, and a threaded post is installed within each lifting groove. The threaded post is rotatably connected to the movable plate, and a lifting block is threaded onto each threaded post. A lifting plate is fixedly connected to one side of each lifting block. A rubber layer is provided at the lower end of each lifting plate, and the rubber layer is adhered to the lifting plate. A rotating disk is fixedly connected to the threaded post at the upper end of each threaded post.

[0006] As a further embodiment of this utility model: a first sliding groove is provided on one side of the rotating seat, and a second sliding groove is provided on the other side of the rotating seat. A double-headed motor is provided in the second sliding groove, wherein the double-headed motor is fixedly installed in the second sliding groove, and a lead screw is provided at both ends of the double-headed motor, wherein the lead screw is rotatably connected to the rotating seat. A sliding rod is provided in the first sliding groove, wherein both ends of the sliding rod are fixedly connected to the rotating seat.

[0007] As a further embodiment of this utility model: a first slider is fixedly connected to the lower end of one side of each of the two movable plates, and a second slider is fixedly connected to the lower end of the other side of each of the two movable plates. The first sliders are all locked in the first slide groove and are slidably connected to the slide rod. The second sliders are all locked in the second slide groove and are threadedly connected to the lead screw.

[0008] As a further embodiment of this utility model: a rotating shaft is fixedly connected to one side of the rotating seat, wherein the rotating shaft is rotatably connected to the base, and a rotating shaft is fixedly connected to the other side of the rotating seat, wherein the rotating shaft is rotatably connected to the base, and a worm gear is provided on the outer wall of the rotating shaft, wherein the worm gear is fixedly connected to the rotating shaft.

[0009] As a further embodiment of this utility model: a controller is fixedly installed on the left side of the base, and a support plate is fixedly connected to the right side of the base. A servo motor is installed on the support plate, and the servo motor is bolted to the support plate. A worm gear is fixedly connected to the power output end of the servo motor, and the worm gear meshes with a worm wheel. Two support blocks are fixedly connected to the support plate, and the worm gear is rotatably connected to the support blocks.

[0010] Compared with the prior art, the beneficial effects of this utility model are: Full-size adaptive design, eliminating reliance on customization: By splicing interlocking plates and adjusting the spacing of moving plates, interlocking plate one and interlocking plate two can be spliced ​​to create bearing surfaces of different lengths. With the help of a dual-head motor-driven lead screw to adjust the spacing of moving plates, it can adapt to circuit boards of different sizes. There is no need to customize fixtures for different board types, which directly reduces fixture costs and changeover time, and meets the needs of multi-variety small-batch production.

[0011] Elastic buffer clamping, non-destructive protection of circuit boards: The rubber layer at the bottom of the lifting plate provides elastic buffering when pressing the circuit board, avoiding scratches to copper foil and circuits by hard claws (especially suitable for flexible circuit boards); In addition, the manual rotating disc adjusts the threaded column, which can flexibly control the pressing force to adapt to boards of different thicknesses, ensuring clamping stability and achieving "flexible fixation" to reduce yield loss.

[0012] Servo-driven angle adjustment for precise adaptation of multiple processes: Starting the servo motor causes the worm gear to rotate, which in turn drives the second rotating shaft to rotate. The second rotating shaft then drives the rotating seat to rotate, which in turn drives the first and second moving plates to rotate. These moving plates then drive the circuit board to rotate. This allows for precise control of the circuit board's tilt angle, covering the needs of multiple processes such as welding (without obstruction of edge components) and visual inspection (at specific observation angles). It replaces the crude operation of manually using inclined blocks, significantly improving processing accuracy and efficiency. Attached Figure Description

Moving plate one 14 and moving plate two 25 are in contact with the left and right sides of the circuit board, limiting their movement. Manually rotate the rotating disk 17, which drives the threaded column 18 to rotate. The threaded column 18 drives the lifting block 20 to move downward, and the lifting block 20 drives the lifting plate 21 to move downward. The lifting plate 21 can press the edge of the circuit board, fixing it on the first interlocking plate 23 and the second interlocking plate 24. The rubber layer 22 at the lower end of the lifting plate 21 acts as a buffer to prevent damage to the circuit board when the lifting plate 21 presses down. Then, when it is necessary to adjust the tilt angle of the circuit board, start the servo motor 4 to drive the worm gear 5 to rotate. The worm gear 5 drives the worm wheel 6 to rotate, and the worm wheel 6 drives the second rotating shaft 27 to rotate. The second rotating shaft 27 drives the rotating seat 8 to rotate, and the second rotating seat 8 drives the first moving plate 14 and the second moving plate 25 to rotate. The first moving plate 14 and the second moving plate 25 drive the circuit board to rotate, thus adjusting the tilt angle of the circuit board.
