Description

Technical Field

[0001] This application relates to the technical field of copper busbar processing equipment, specifically a combined copper busbar processing gripping device. Background Technology

[0002] Copper busbars are large-section rectangular copper conductors primarily used for the efficient transmission of high currents ranging from hundreds to tens of thousands of amperes, providing low-impedance, high-reliability conductive connections between electrical equipment. Leveraging their pure copper material, current carrying capacity per unit cross-sectional area more than 1.5 times that of cables, and excellent heat dissipation due to their flat structure, they are widely used in high-current scenarios such as substations, industrial equipment, and new energy systems. They are particularly useful in space-constrained, high-frequency current, or high-safety-requirement electrical systems, replacing cables and significantly reducing energy consumption and failure risks.

[0003] When processing copper busbars, multiple copper plates need to be welded together. The traditional method is for the user to hold the copper plates and fix them on the fixture, then adjust the position of each copper plate before welding. This method of processing copper busbars is inefficient. Therefore, there is an urgent need for a combined copper busbar processing gripping device to solve the above problems. Utility Model Content

[0004] This application provides a gripping device for processing modular copper busbars, which can realize the automatic gripping and placement of copper plates, effectively improving the processing efficiency of modular copper busbars and effectively solving the problems in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a combined copper busbar processing gripping device, including a mounting frame, on the upper surface of which a geared motor is mounted; the mounting frame is rotatably connected to a main shaft via a bearing disposed on its outer side, and the output shaft of the geared motor drives the main shaft to rotate via a gear transmission mechanism.

[0006] A rotary table is mounted on the lower end face of the spindle. A fixed plate is provided on the right end of the lower surface of the rotary table. An electrically controlled telescopic rod II is mounted on the outer side of the rotary table. A movable plate is mounted on the telescopic end of the electrically controlled telescopic rod II. An installation plate is mounted on the lower surface of the movable plate. An electrically controlled telescopic rod I is mounted on the outer side of both the installation plate and the fixed plate. A movable clamping plate is mounted on the telescopic end of the electrically controlled telescopic rod I.

[0007] Both the mounting plate and the fixed plate have rotating clamps connected to their front sides via a flipping mechanism. The outer side of the rotating clamp is provided with a mounting groove facing the moving clamp. An electrically controlled telescopic rod three is installed inside the mounting groove, and a negative pressure suction nozzle is installed at the telescopic end of the electrically controlled telescopic rod three.

[0008] Preferably, the gear transmission mechanism includes a driving gear and a driven gear, which mesh with each other. The driving gear is mounted on the output shaft of the geared motor, and the driven gear is mounted on the main shaft via a spline.

[0009] Preferably, the rotating clamp rotates only between 0 and 90 degrees.

[0010] Preferably, the flipping mechanism includes an adjusting shaft and a stepper motor. The two stepper motors are respectively fixedly installed on the outer sides of the mounting plate and the fixed plate. The output shaft of the stepper motor is connected to the end of the adjusting shaft, and the adjusting shaft is fixedly connected to the rotating clamp.

[0011] Preferably, the rotating clamp and the moving clamp are configured to engage in a corresponding manner.

[0012] Preferably, the negative pressure nozzle is connected to an external vacuum pump via a conduit.

[0013] Compared with the prior art, the beneficial effects of this application are:

[0014] 1. This application completely replaces manual operation by coordinating the control of the electric telescopic rod assembly, the stepper motor flipping mechanism and the rotary table, realizing automatic gripping, multi-angle flipping and precise positioning of copper busbars, significantly improving processing accuracy and consistency, and solving the problems of low efficiency and easy deviation of traditional manual placement;

[0015] 2. The mechanical clamping plate and negative pressure adsorption complement each other, which can stably grip regular copper busbars and adsorb irregular or thin-walled copper busbars without damage; combined with the multi-angle flipping function, it can meet the needs of multiple processes such as welding and bending, while avoiding damage to the surface of the copper busbar.

[0016] 3. The modular design supports quick switching between different specifications of copper busbars, greatly shortening the changeover time; the integrated structure with gripping, positioning and flipping functions reduces equipment transfer links, significantly improves production efficiency, and at the same time reduces the inventory of special fixtures and the cost of multi-equipment collaboration.

Figure 2 The orientations or positional relationships shown are for the convenience of describing this application and simplifying the description only, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0023] Please see Figure 1-3 This application provides the following technical solution: a combined copper busbar processing gripping device, including a mounting frame 9, on the upper surface of the mounting frame 9 is a geared motor 1; the mounting frame 9 is rotatably connected to a main shaft 11 through a bearing set on its outer side, and the output shaft of the geared motor 1 drives the main shaft 11 to rotate through a gear transmission mechanism 10.

[0024] A rotary table 2 is mounted on the lower end face of the spindle 11. A fixed plate 8 is provided on the right end of the lower surface of the rotary table 2. An electrically controlled telescopic rod 12 is mounted on the outer side of the rotary table 2. A movable plate 3 is mounted on the telescopic end of the electrically controlled telescopic rod 12. An installation plate 4 is mounted on the lower surface of the movable plate 3. An electrically controlled telescopic rod 5 is mounted on the outer side of both the installation plate 4 and the fixed plate 8. A movable clamping plate 6 is mounted on the telescopic end of the electrically controlled telescopic rod 5.

[0025] The front sides of both the mounting plate 4 and the fixed plate 8 are rotatably connected to a rotating clamping plate 7 via a flipping mechanism 13. The outer side of the rotating clamping plate 7 facing the moving clamping plate 6 is provided with a mounting groove 14. An electrically controlled telescopic rod 15 is installed inside the mounting groove 14. A negative pressure suction nozzle 16 is installed at the telescopic end of the electrically controlled telescopic rod 15.

[0026] Specifically, the geared motor 1 drives the main shaft 11 to rotate, providing a 360° working range without blind spots in the horizontal plane; the electrically controlled telescopic rod 12 drives the moving plate 3 to extend and retract laterally, flexibly adapting to copper busbars of different widths. The system integrates mechanical clamping and negative pressure adsorption modes, ensuring non-destructive gripping of both conventional copper busbars and irregularly shaped thin-walled parts.

[0027] Furthermore, the gear transmission mechanism 10 includes a driving gear and a driven gear, which mesh with each other. The driving gear is mounted on the output shaft of the reduction motor 1, and the driven gear is mounted on the main shaft 11 via a spline.

[0028] Specifically, the spline connection design enables zero-backlash power transmission.

[0029] Furthermore, the rotating clamp 7 rotates only between 0 and 90 degrees.

[0030] Specifically, the 0° position allows for horizontal gripping of copper busbars, suitable for handling, punching, and other processes; the 90° position provides vertical positioning, meeting the vertical assembly requirements during welding and bending.

[0031] Furthermore, the flipping mechanism 13 includes an adjustment shaft 131 and a stepper motor 132. The two stepper motors 132 are respectively fixedly installed on the outer sides of the mounting plate 4 and the fixing plate 8. The output shaft of the stepper motor 132 is connected to the end of the adjustment shaft 131, and the adjustment shaft 131 is fixedly connected to the rotating clamp 7.

[0032] Furthermore, the rotating clamp 7 and the movable clamp 6 are configured to engage and correspond to each other.

[0033] Specifically, the interlocking clamping design provides double locking protection.

[0034] Furthermore, the negative pressure suction nozzle 16 is connected to an external vacuum pump via a conduit.

[0035] In use: stack the copper plates to be processed together. When grabbing the copper plates, the stepper motor 132 drives the rotating clamp 7 to rotate 90 degrees clockwise, so that the negative pressure suction nozzle 16 faces the direction. Then the electric telescopic rod 3 15 pushes out the negative pressure suction nozzle 16. The external lifting mechanism drives the device to move down until the negative pressure suction nozzle 16 contacts the surface of the copper plate.

[0036] The external vacuum pump is started, allowing the negative pressure suction nozzle 16 to lift the top copper plate. After the copper plate rises a certain distance with the device, the stepper motor 132 drives the rotating clamping plate 7 to rotate counterclockwise by 90 degrees. Simultaneously, the electrically controlled telescopic rod 15 pushes the moving clamping plate 6 towards the rotating clamping plate 7 until the moving clamping plate 6 presses the copper plate tightly against the outer surface of the rotating clamping plate 7. At this time, the electrically controlled telescopic rod 35 retracts to retract the negative pressure suction nozzle 16. The position of the copper plate can be adjusted by rotating the reduction motor 1, so that the copper plate can be accurately connected with other copper plates, which facilitates the subsequent welding of copper plates.

[0037] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
