Description

Technical Field

[0001] This utility model relates to the field of product screw assembly technology, specifically a multi-station automatic screw assembly machine. Background Technology

[0002] Multi-station automatic screw assembly machines are highly efficient automated equipment that achieves automatic screw feeding, positioning, tightening, and inspection throughout the entire process through multi-station collaborative operation. Its core components include a feeding mechanism, a multi-station turntable, an assembly line, a tightening module, a vision positioning system, and a control system. The equipment uses an indexing plate or conveyor belt to facilitate the flow of workpieces between different stations. Each station has a clearly defined function, such as feeding, positioning, screw conveying, tightening, torque detection, and defective product sorting. Through programming, it can adapt to different screw and workpiece specifications, supporting flexible production. Compared to manual assembly, it significantly improves production efficiency, reduces labor costs, and ensures tightening accuracy and consistency, making it widely used in large-scale production scenarios in the electronics, automotive, and home appliance manufacturing industries.

[0003] In existing technologies, when installing screws, simple pneumatic screwdrivers are used to assemble and fix the screws, eliminating the need for manual tightening by workers. This reduces the workload and improves efficiency to some extent. However, when using a simple pneumatic screwdriver, only a single screw can be tightened, resulting in low efficiency and repetitive work for workers. This makes it difficult to promote and use, leading to poor practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a multi-station automatic screw assembly machine, which can effectively solve the problem that the existing technology can only tighten a single screw, resulting in low work efficiency and repetitive work for the workers, which makes it difficult to promote and use and has poor practicality.

[0005] The technical solution adopted by this utility model is: a multi-station automatic screw assembly machine, including a workbench and four columns fixedly installed on the top of the workbench. A top plate is fixedly installed on the end of the column away from the workbench. A cylinder is fixedly installed on the side of the top plate away from the column. A moving plate is fixedly installed on the output end of the cylinder. A fixed plate is fixedly installed on the end of the column away from the top plate. A drive assembly is provided on the outer wall of the moving plate.

[0006] Preferably, the movable plate is slidably connected to the column, and the movable plate is located above the fixed plate.

[0007] Through the above technical solution, during assembly, the cooperation between the movable plate and the column guides the movable plate, thereby improving the overall stability.

[0008] Preferably, the drive assembly includes a first mounting plate, a motor, a fixed rod, a second mounting plate, a cylinder, a slide groove, a screw, a spring, a screwdriver bit, a positioner, and a coupling. The motor is fixedly mounted on the outer wall of the first mounting plate. A coupling is fixedly mounted on the output end of the motor. A fixed rod is fixedly mounted on the end of the coupling away from the motor. The second mounting plate is fixedly mounted on the end of the first mounting plate near the moving plate. A cylinder is fixedly mounted on the end of the second mounting plate away from the first mounting plate. A slide groove is fixedly mounted on the end of the cylinder near the fixed rod.

A screwdriver bit is fixedly mounted on the end of the fixed rod away from the motor. A positioner is fixedly mounted on the end of the cylinder away from the fixed rod.

[0009] Using the above technical solution, the operator starts the cylinder, causing the drive component to move downwards. When the positioner comes into contact with the screw to be installed, the motor is started. The output shaft of the motor rotates and drives the fixed rod to rotate through the coupling, thereby driving the screwdriver head to rotate, which can realize the rapid assembly of the screw.

[0010] Preferably, the screw is slidably connected to the slide groove, the slide groove has a "waist hole" shaped cross-section, and the screw extends through the fixing rod and the slide groove to the outside of the cylinder.

[0011] The above technical solution, through the cooperation of the screw and the slide, guides the fixing rod during assembly and also limits its movement, preventing the fixing rod from moving too far downward and damaging the screwdriver head. It is highly practical.

[0012] Preferably, one end of the spring abuts against the coupling, and the other end of the spring abuts against the cylinder.

[0013] The above technical solution, through the design of the spring, allows the screwdriver head to quickly return to its original position after assembly, facilitating the next assembly and demonstrating high practicality.

[0014] Preferably, there are six identical drive components, which are distributed at equal intervals.

[0015] The above technical solution, through the design of six drive components, enables the simultaneous assembly of six screws, further improving the overall assembly efficiency.

[0016] Preferably, both the movable plate and the fixed plate adopt a hollow design, and the center lines of the movable plate and the fixed plate are located on the same setting line.

[0017] The above technical solution, with both the moving plate and the fixed plate adopting a hollow structure design, will not interfere with the normal operation of the drive components during assembly, making assembly convenient and highly practical.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: like Figure 1-6 As shown, the present invention provides a multi-station automatic screw assembly machine, including a workbench 1 and four columns 2 fixedly installed on the top of the workbench 1. A top plate 3 is fixedly installed on the end of the column 2 away from the workbench 1. A cylinder 4 is fixedly installed on the side of the top plate 3 away from the column 2. A movable plate 5 is fixedly installed on the output end of the cylinder 4. A fixed plate 6 is fixedly installed on the end of the column 2 away from the top plate 3. A drive assembly 7 is provided on the outer wall of the movable plate 5.

[0023] Specifically, the movable plate 5 is slidably connected to the column 2, and the movable plate 5 is located above the fixed plate 6. The advantage is that during assembly, the cooperation between the movable plate 5 and the column 2 guides the movable plate 5, improving overall stability.

[0024] Specifically, the drive assembly 7 includes a mounting plate 701, a motor 702, a fixing rod 703, a mounting plate 704, a cylinder 705, a slide 706, a screw 707, a spring 708, a screwdriver head 709, a positioner 710, and a coupling 711. The motor 702 is fixedly mounted on the outer wall of the mounting plate 701. The coupling 711 is fixedly mounted on the output end of the motor 702. The fixing rod 703 is fixedly mounted on the end of the coupling 711 away from the motor 702. The fixed plate 6 is located near the moving plate 5. A mounting plate 704 is fixedly installed. A cylinder 705 is fixedly installed at the end of the mounting plate 704 furthest from the fixed plate 6. A sliding groove 706 is fixedly installed at the end of the cylinder 705 closest to the fixed rod 703. A screw 707 is inserted into the end of the fixed rod 703 furthest from the motor 702. A spring 708 is provided on the outer wall of the fixed rod 703. A screwdriver head 709 is fixedly installed at the end of the fixed rod 703 furthest from the motor 702. A positioner 710 is fixedly installed at the end of the cylinder 705 furthest from the fixed rod 703. The advantage is that when the operator starts the cylinder 4, the drive assembly 7 moves downward. When the positioner 710 comes into contact with the screw to be installed, the motor 702 is started. The output shaft of the motor 702 rotates, driving the fixed rod 703 to rotate via the coupling 711, thereby driving the screwdriver head 709 to rotate, enabling rapid screw assembly.

[0025] Specifically, the screw 707 is slidably connected to the slide groove 706. The slide groove 706 has a "waist hole" shaped cross-section. The screw 707 extends through the fixed rod 703 and the slide groove 706 to the outside of the cylinder 705. The advantage is that the screw 707, through the cooperation of the slide groove 706, guides the fixed rod 703 during assembly and also limits its movement, preventing excessive downward movement of the fixed rod 703 and damage to the screwdriver head 709. This design is highly practical.

[0026] Example 2: like Figure 2-6 As shown, as an improvement on the previous embodiment, to further improve work efficiency, specifically, six identical drive components 7 are provided, and the six drive components 7 are distributed at equal intervals. The advantage is that, through the design of six drive components 7, six screws can be assembled simultaneously, further improving overall assembly efficiency.

[0027] Specifically, one end of spring 708 abuts against coupling 711, and the other end of spring 708 abuts against cylinder 705. The advantage is that, through the design of spring 708, the screwdriver head 709 can quickly return to its original position after assembly, facilitating the next assembly and making it highly practical.

[0028] Specifically, both the movable plate 5 and the fixed plate 6 adopt a hollow design, and their center lines are located on the simultaneous setting line. The advantage is that, by using a hollow structure for both the movable plate 5 and the fixed plate 6, the normal operation of the drive component 7 will not be interfered with during assembly, making assembly convenient and highly practical.

[0029] Working Principle: Before assembly, the operator connects the external power supply. Then, the operator places the screws to be assembled on the assembly area of ​​the workbench. During assembly, the operator activates cylinder 4, causing drive assembly 7 to move downwards. When the positioner 710 contacts the screws, motor 702 is activated. The output shaft of motor 702 rotates, driving the fixed rod 703 to rotate via coupling 711, thereby rotating the screwdriver head 709. This enables rapid screw assembly. The screw 707, in conjunction with the sliding groove 706, guides and limits the movement of the fixed rod 703 during assembly. To prevent excessive downward movement of the fixing rod 703 and damage to the screwdriver head 709, the design of the spring 708 ensures that the screwdriver head 709 can quickly return to its original position after assembly, facilitating the next assembly. The cooperation between the moving plate 5 and the column 2 guides the moving plate 5 during assembly, improving overall stability. The hollow structure design of both the moving plate 5 and the fixing plate 6 prevents interference with the normal operation of the drive assembly 7 during assembly, facilitating assembly and enhancing practicality. The design of six drive assemblies 7 allows for the simultaneous assembly of six screws, further improving overall assembly efficiency.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
