Description

Technical Field

[0001] This application relates to the field of copper busbar processing equipment technology, and in particular to a punching device for integrated copper busbar processing. Background Technology

[0002] Copper busbars, as an important conductive material, are widely used in the power and electrical industries. Punching, cutting, and polishing are common processes in the production and processing of copper busbars. While integrated punching and cutting machines exist, polishing still requires manual operation.

[0003] Therefore, in actual use, the operator needs to place the copper strip on the feed end of the punching and cutting machine (also known as a CNC idle punching and shearing machine), and use the punching and cutting machine to automatically punch and cut the copper strip to form several copper bars. Finally, the operator uses a handheld polishing machine to polish the edges of each formed copper bar to remove burrs, surface stains and other effects.

[0004] When using this method, one worker is generally needed for each piece of equipment. However, after each copper bar is processed, the worker needs to polish each copper bar before a new copper bar can be loaded, which restricts the production efficiency of copper bars.

[0005] Alternatively, one staff member can be responsible for feeding and handling the cut and shaped copper busbars, while multiple staff members can be responsible for the subsequent polishing work. However, this would result in excessively high labor costs.

[0006] With the continuous development of industrial automation technology, the demand for improving production efficiency, reducing labor costs, and ensuring processing quality is becoming increasingly urgent. Therefore, it is particularly important to develop an automated copper busbar processing device that integrates punching, cutting, and polishing functions. Summary of the Invention

[0007] The purpose of this application is to provide a punching device for integrated processing of copper busbars, which integrates punching, cutting and polishing functions to achieve the beneficial effect of cost reduction and efficiency improvement.

[0008] The punching device for integrated processing of copper busbars provided in this application adopts the following technical solution: An integrated punching device includes a punching and cutting integrated machine body. The punching and cutting integrated machine body has a feeding end and a discharging end on both sides, and also includes two polishing mechanisms. The two polishing mechanisms are located on the upper and lower sides of the discharging end, respectively. Each polishing mechanism includes a lifting mechanism, a drive component, and a polishing belt. The drive component is mounted on the lifting mechanism, and the lifting mechanism is used to drive the working height of the drive component. One end of the polishing belt is sleeved on the drive component, and the other end of the polishing belt can be sleeved on a copper busbar. The drive component can control the high-speed transmission of the polishing belt.

[0009] By adopting the above technical solution, during use, the operator only needs to place the copper strip into the punching and cutting integrated machine body through the feeding end. Then, the punching and cutting machine body punches and cuts the copper strip. When the initially cut copper busbar is output from the discharge end, two polishing mechanisms are used to grind and polish the upper and lower sides of the copper busbar respectively to remove burrs. When polishing the copper busbar, the lifting mechanism drives the drive component to move away from the copper busbar, so that the two ends of the polishing belt are tightly connected to the drive component and the copper busbar respectively. Then, the drive component drives the polishing belt to achieve the effect of controlling the polishing belt to polish the surface of the copper busbar.

[0010] Optionally, the lifting mechanism is configured as a first rodless cylinder, the slide of the rodless cylinder is fixed with a mounting base, and the drive assembly is mounted on the mounting base.

[0011] By adopting the above technical solution, the rodless cylinder is low in cost and easy to use. The mounting base set on the rodless cylinder can be used to support the drive components.

[0012] Optionally, the drive assembly includes a motor, a drive wheel, and a clamping wheel. The motor is mounted on a mounting base, the drive wheel is mounted on the output shaft of the motor, and two clamping wheels are provided, each located on one side of the drive wheel. Both clamping wheels are rotatably connected to the mounting base. The polishing belt is sleeved on the drive wheel, and the outer side of the polishing belt is in contact with the two clamping wheels.

[0013] By adopting the above technical solution, the motor drives the drive wheel to rotate, which can achieve the traction of the tensioned polishing belt. The pressure wheel cooperates with the drive wheel to clamp the polishing belt.

[0014] Optionally, two annular limiting parts are provided on the outer surface of the drive wheel, and the two annular limiting parts are respectively provided on both sides of the drive wheel. When the polishing sand belt is sleeved on the drive wheel, the polishing sand belt is located between the two annular limiting parts.

[0015] By adopting the above technical solution, the annular limiting part can restrict the position of the polishing belt, prevent the polishing belt from detaching from the drive wheel when the drive wheel rotates at high speed, and ensure the safe use of the polishing belt.

[0016] Optionally, the mounting base is arranged in an "L" shape. The horizontal part of the mounting base is located on the side of the motor away from the copper discharge position. The motor is mounted on the horizontal part of the mounting base. A vertical groove is provided on the vertical part of the mounting base. A slider is slidably connected in the groove. The pressure wheel is mounted on the slider. A spring is provided between the slider and the horizontal part of the mounting base. The spring is used to apply a force to the slider to move it in the direction of the motor.

[0017] By adopting the above technical solution, the spring can always apply a force to the slider in the direction of the driving wheel, so that the slider can drive the clamping wheel to move in the direction of the driving wheel, ensuring that the clamping wheel can cooperate with the driving wheel to clamp the polishing sand belt.

[0018] Optionally, a protective cover is also included. The protective cover is installed on the discharge end by means of bolt fastening. The protective cover covers two polishing mechanisms. The protective cover is provided with an outlet for copper busbar output. The side of the protective cover connected to the storage end is open. A transparent observation port is provided on one side of the protective cover.

[0019] By adopting the above technical solution, some polishing dust will be generated when the polishing belt polishes the copper strip. The protective cover can intercept the polishing dust and prevent foreign objects from entering between the polishing belt and the copper strip, thus ensuring the safe use of the polishing belt. The transparent observation port set on the protective cover allows the staff to observe the real-time polishing status of the copper strip.

[0020] Optionally, a hooking mechanism is also included, which includes a slide rail, a second telescopic cylinder, and a hook rod. The slide rail is installed inside the protective cover. The upper end of the hook rod is slidably connected to the slide rail via a sliding seat. The second telescopic cylinder is installed inside the protective cover to drive the hook rod to rise and fall. The lower end of the hook rod is provided with a hook body, which is used to pull up the polishing sand belt that can press against the upper surface of the copper busbar.

[0021] By adopting the above technical solution, after a copper strip is polished, the upper end of the polishing abrasive belt used to polish the upper surface of the copper busbar lacks support and may fall directly, which is not conducive to the next polishing action. Therefore, by using the cooperation between the second telescopic cylinder and the slide rail, the hook rod can be driven to move up and down, thereby hooking the fallen polishing abrasive belt upward, so that the new copper strip can pass through the polishing abrasive belt for the next polishing process.

[0022] Optionally, the two polishing mechanisms are arranged along the moving direction of the copper busbar. The hook rod includes two parallel extension rods. The upper ends of the two extension rods are connected to the hook rod as a whole. The hook body is formed by horizontally bending the lower ends of the two extension rods toward the direction of the discharge end. The copper busbar can pass through the space between the two extension rods. When the polishing belt is tensioned in cooperation with the hook rod, the hook body is located within the enclosure of the polishing belt.

[0023] By adopting the above technical solution, the hook body is used to hook the polishing abrasive belt, and the extension rod is used to avoid the copper belt, so as to prevent interference with the copper belt when the hook rod is raised and lowered to adjust the top position of the polishing abrasive belt, thus ensuring the safety of the hook rod in use.

[0024] Optionally, the protective cover is also equipped with an exhaust fan, the air inlet of which is connected to the interior of the protective cover, and a dust filter is installed on the air outlet of the exhaust fan.

[0025] By adopting the above technical solution, the exhaust fan can effectively remove the polishing dust generated during the polishing process, preventing too much polishing dust from accumulating inside the protective cover and further ensuring safe use.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. It can automatically polish the punched and cut copper strips, achieving the beneficial effect of cost reduction and efficiency improvement; 2. It can be used to retrofit existing punching and cutting machines, avoiding excessive cost increases, while generating significant economic benefits. 3. It can be used for processing copper strips of different sizes, has a wide range of applications, and does not require repeated adjustments. Attached Figure Description
