Description

Technical Field

[0001] This utility model belongs to the field of circuit board manufacturing technology, and in particular relates to a rapid positioning and fixing device for circuit board production. Background Technology

[0002] Circuit board manufacturing technology has advanced with the development of the electronics industry. In order to adapt to the miniaturization and high performance of electronic products, it is necessary to improve the integration of circuit boards, optimize heat dissipation and signal transmission, cope with environmental pressures, develop green processes, and at the same time meet the alignment requirements of multilayer boards and the special needs of flexible circuit boards.

[0003] In the circuit board manufacturing process, the circuit boards need to be positioned and fixed to ensure the accuracy and quality of subsequent processing steps. Existing positioning and fixing devices usually require operators to manually adjust and operate multiple positioning and fixing components separately. The operation steps are cumbersome and it is difficult to quickly and accurately fix the circuit board in the predetermined position. Furthermore, during the fixing process, the circuit board is prone to uneven force due to the uncoordinated operation of various components, resulting in positional displacement or damage, which affects production efficiency and product quality.

[0004] Therefore, this utility model provides a rapid positioning and fixing device for circuit board production to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a rapid positioning and fixing device for circuit board production. By combining the composite drive clamping plate assembly and the lifting assembly, it solves the problem in the prior art that the circuit board production process cannot be quickly positioned and fixed, which affects the work efficiency of the circuit board production process.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a rapid positioning and fixing device for circuit board production, comprising a worktable, a composite drive clamping plate assembly, and a lifting assembly. The bottom of the worktable is fixedly connected to the lifting assembly. The composite drive clamping plate assembly includes two first cylinders, the bottom of which is fixedly connected to the worktable via a bracket. Push plates are fixedly connected to the output ends of the two first cylinders on opposite sides, and adjustment mechanisms are fixedly connected to the opposite sides of the two push plates. Mounting brackets are fixedly connected to the front and rear sides of the output ends of the adjustment mechanisms, and pulley shafts are fixedly connected to both sides of the inner wall of the mounting brackets. Pulleys are slidably connected to the surfaces of the pulley shafts. The lifting assembly includes a second motor, the top of which is fixedly connected to the worktable. A gear is fixedly connected to the left side of the output end of the second motor, and a rack is meshed with the rear side of the gear. A bearing plate is fixedly connected to the top of the rack. A suction mechanism is connected to both sides of the bottom of the bearing plate, and a limit mechanism is fixedly connected to both sides of the bottom of the worktable.

[0008] The present invention is further configured such that the adjustment mechanism includes two first motors, the left side of the first motors is fixedly connected to the push plate, the front side of the output end of the first motors is fixedly connected to a screw, the surface of the screw is threaded with a nut, the right side of the nut is fixedly connected to the mounting bracket, the two first motors are fixed to the right side of the mounting bracket to provide power, and their output ends drive the screw to rotate. The screw and the nut fixed to the mounting bracket on the right side are threadedly engaged, converting the rotational motion into linear motion, thereby driving the relevant components to move to achieve precise positioning and fixation of the circuit board.

[0009] The present invention is further configured such that a top plate is fixedly connected to the top of the inner cavity of the mounting bracket, and a buffer pad is installed on the surface of the pulley. The top plate serves as a shield and protection to prevent foreign objects from falling into the inner cavity and affecting the operation of the component. The buffer pad installed on the surface of the pulley can reduce the impact of collision when in contact with the circuit board, avoid damage to the surface of the circuit board, and enhance the fit when in contact.

[0010] The present invention is further configured such that a sliding rod is fixedly connected to the top of the mounting bracket, and a slider is slidably connected to the surface of the sliding rod. One side of the slider is fixedly connected to the top of the mounting bracket. When the slider slides on the surface of the sliding rod, it can assist the mounting bracket in adjusting its position. Furthermore, the fact that one side of the slider is fixed to the top of the mounting bracket can enhance the stability of the mounting bracket during movement and reduce shaking to ensure the smooth operation of the overall structure.

[0011] The present invention is further configured such that the limiting mechanism includes two electric push rods, the top of which is fixedly connected to the worktable, and the output ends of the two electric push rods on opposite sides are fixedly connected to limiting blocks. The two electric push rods are fixed to the top of the support plate to provide driving force, and their output ends drive the limiting blocks at the top to move. The limiting blocks block the rack column by adjusting their position to prevent deviation during lifting or moving, and ensure its position is stable.

[0012] The present invention is further configured such that the air extraction mechanism includes an air extraction barrel, the top of which extends through to the top of the support plate. A piston is movably connected to the inner cavity of the air extraction barrel, and a second cylinder is fixedly connected to the bottom of the piston. A support plate is fixedly connected to the bottom of the second cylinder. The top of the air extraction barrel extends through to the top of the support plate, providing a channel for air extraction. The piston in its inner cavity can move under the drive of the second cylinder. The second cylinder provides power to drive the piston to move. By changing the air pressure inside the air extraction barrel through the movement of the piston, the circuit board on the support plate can be adsorbed and fixed.

[0013] The present invention is further configured such that support frames are fixedly connected to both sides of the bottom of the workbench, and the bottom of the support frame is fixedly connected to a support plate. The support plate increases the contact area with the ground, enhances the stability of the overall structure, and prevents the device from shaking or tipping over during operation.

[0014] The present invention is further configured such that a central control screen is fixedly connected to the front side of the support frame, and both sides of the central control screen are fixedly connected to the support frame by quick-release screws. The central control screen is used to centrally control and monitor the operating status of each component of the device. The two sides are fixed to the support frame by quick-release screws, which facilitates quick disassembly and installation of the central control screen for maintenance or replacement.

It can be adapted to circuit boards of different specifications, enhance the applicability of the device, and at the same time, the connection of each component is firm, reducing the shaking during operation and ensuring safe and efficient operation.

[0017] 2. This utility model uses a lifting assembly. The second motor in the lifting assembly is fixedly to the worktable. Its output end drives the gear and rack to mesh and transmit power, which can stably adjust the height of the support plate to adapt to different operating needs. The limiting mechanism on the surface of the rack ensures that the lifting process is smooth and does not deviate. The air extraction mechanism at the bottom of the support plate can enhance the fixing effect on the object. The overall structure is tightly fitted, which improves the reliability and ease of operation of the device. At the same time, the reasonable connection of each component helps to improve the overall work efficiency. Attached Figure Description
