Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a PCB board processing and assembly fixture. Background Technology

[0002] Utility model patent CN209676623U discloses a PCB and fixture assembly device, including a PCB support plate. Two sets of rotating brackets are symmetrically welded to the bottom of the PCB support plate, and sliding connecting rods are inserted into the left and right sides of each rotating bracket. A torsion spring shaft is inserted through the sliding connecting rod and the rotating bracket, and a clamping sleeve is welded to the inner wall of the top of the sliding connecting rod. Four sets of negative pressure suction cups are evenly spaced on the upper surface of the PCB support plate, and a sliding column is inserted into the center of the bottom of the PCB support plate. The lower end of the sliding column is inserted into a base, and a buffer washer is fitted between the base and the PCB support plate and the sliding column. A limit plate is threadedly installed at the bottom of the sliding column. This device uses negative pressure suction cups to fix the PCB board with negative pressure, improving the positioning and installation efficiency, while avoiding the problem of the PCB board warping upwards due to excessive pressure from the clamping sleeve, which affects the welding quality. However, this device still has some shortcomings in use: the device is not convenient for adjusting the angle of the PCB board, making the installation of some electrical components inconvenient. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a PCB board processing and assembly fixture, which solves the problem that the device is not convenient to adjust the angle of the PCB board, making the installation of some electrical components inconvenient.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a PCB board processing and assembly fixture, comprising a base, a support shaft fixedly connected to the upper end of the base, a steel ball fixedly connected to the upper end of the support shaft, a support movably connected to the outer side of the steel ball, an end cap threadedly connected to the outer side of the support, the end cap contacting the steel ball, a tray fixedly connected to the upper end of the support, an adjustment mechanism provided on the base, a clamping mechanism provided on the tray, and a worktable provided on the clamping mechanism.

[0005] Preferably, the adjustment mechanism includes a support plate, with the support plate fixedly connected to the upper end of the base. A cylinder is fixedly installed on the right side of the support plate, with the cylinder rod passing through the support plate and slidably connected to it. A sliding plate is fixedly connected to the end of the cylinder rod, and the sliding plate is slidably connected to the base. A guide ball is also fixedly connected to the upper end of the sliding plate, and a conical ring is slidably connected to the lower end of the support plate. The conical ring and the guide ball are slidably connected. By rotating the support plate and driving the sliding plate to move via the cylinder, the guide ball slides within the conical ring, thereby changing the angle of the conical ring. This allows for adjustment of the angle of the worktable and the angle of the PCB board on the worktable, facilitating installation and use.

[0006] Preferably, a guide block is fixedly connected to the upper end of the conical ring, and the guide block and the support plate are slidably connected. By setting the guide block, the distance between the conical ring and the support plate is limited.

[0007] Preferably, the clamping mechanism includes a screw seat. The upper end of the support plate is fixedly connected to the screw seat, which is fixedly connected to the worktable. A motor is fixedly installed at the lower end of the worktable. A square rod is fixedly connected to the lower end of the motor's shaft. A turntable is slidably connected to the outer side of the square rod. The turntable and the screw seat are connected by a thread. A sliding rod is slidably connected to the upper end of the turntable. The sliding rod is slidably connected to the worktable. A screw is installed inside the sliding rod via a bearing. A connecting plate is slidably connected inside the worktable. A clamping block is fixedly connected to the upper end of the connecting plate. The motor drives the square rod to rotate, causing the turntable to rotate, which in turn causes the turntable and the screw seat to perform threaded movement. This locks the turntable after rotation. Furthermore, the rotation of the turntable moves the sliding rod, which in turn moves the clamping block, allowing for stable clamping of PCBs of different sizes.

[0008] Preferably, a sliding pin is fixedly connected to the lower end of the slide rod, and the sliding pin is slidably connected to the turntable. The sliding pin guides the movement of the slide rod.

[0009] Preferably, the screw and the worktable are movably connected, and the screw and the connecting plate are connected by threads. The movement of the connecting plate is controlled by the screw.

[0010] Preferably, a protrusion is fixedly connected to the lower end of the clamping block, and the protrusion is slidably connected to the worktable. The protrusion provides auxiliary support to the clamping block.

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

[0012] 1. This utility model uses a rotating tray and a cylinder to drive the sliding plate to move, which in turn causes the guide ball to slide inside the conical ring, thereby changing the angle of the conical ring. This allows for adjustment of the angle of the worktable and the angle of the PCB board on the worktable, making it convenient for installation and use.

[0013] 2. This utility model uses a motor to drive a square rod to rotate, which in turn drives a turntable to rotate. This causes the turntable and the screw seat to move in a threaded motion, which locks the turntable after it rotates. The rotation of the turntable also drives the slide rod to move, which in turn moves the clamping block. This allows for stable clamping of PCBs of different sizes. Attached Figure Description

By setting the guide block, the conical ring 75 and the support plate 6 are limited. The conical ring 75 and the guide ball 74 are slidably connected. By rotating the support plate 6 and driving the slide plate 73 to move through the cylinder 72, the guide ball 74 slides in the conical ring 75, thereby changing the angle of the conical ring 75. This can change the angle of the worktable 9 and adjust the angle of the PCB board on the worktable 9, which is convenient for installation and use.

[0022] Please see Figures 1-4 The clamping mechanism 8 includes a screw seat 81. The upper end of the support plate 6 is fixedly connected to the screw seat 81, which is fixedly connected to the worktable 9. The lower end of the worktable 9 is fixedly mounted with a motor 82.
