Description

Technical Field

[0001] This invention belongs to the technical field of copper busbar processing equipment, specifically relating to copper busbar machining apparatus and machining methods. Background Technology

[0002] Copper busbars, also known as copper busbars or copper busbars, are conductive components used in power systems to transmit large currents. They are widely used in high and low voltage electrical appliances, switch contacts, and power distribution equipment. Before leaving the factory, copper busbars undergo a series of machining processes such as drilling, chamfering, and polishing to meet installation, connection, and usage requirements.

[0003] Currently, the machining of copper busbars is typically completed in a multi-stage, multi-equipment manner. This involves drilling on one machine, then transferring the workpiece to another for chamfering, and finally to a polishing machine for surface treatment. This method has the following drawbacks: First, the workpiece is transferred between different machines multiple times, and the positioning reference changes repeatedly, making it difficult to guarantee machining accuracy. Second, multiple clamping operations lead to low production efficiency and high labor intensity. Third, for longer copper busbars, bending deformation due to cutting forces during machining can easily occur, affecting the quality of the finished product. Fourth, after drilling, stress concentration easily occurs around the hole wall, making the hole opening prone to plastic deformation during subsequent bending processes, resulting in out-of-tolerance hole diameter or out-of-round hole shape.

[0004] To address the aforementioned issues, there are some integrated processing equipment in the existing technology, but most of them are complex in structure and expensive. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a copper busbar processing device, including a movable platform, a clamping and positioning mechanism, and a processing mechanism. The mobile platform is slidably mounted on the transverse slide rail, and the mobile platform is driven to move laterally on the transverse slide rail by the transverse drive mechanism; The clamping and positioning mechanism includes several clamping plates disposed above the movable platform. The clamping plates are located on both sides or around the movable platform, and the clamping plates are moved toward the center of the movable platform by the moving drive mechanism. The processing mechanism includes a chuck, a rotary drive mechanism for driving the chuck to rotate, a lifting drive mechanism for driving the chuck to move up and down, and a longitudinal drive mechanism for driving the chuck to move longitudinally. The chuck is used to hold the machining tool.

[0006] As a preferred embodiment of the above technical solution, a horizontal slider is installed on the horizontal slide rail, and a horizontal slide plate is provided below the movable platform. The horizontal slider is fixedly connected to the horizontal slide plate. The lower end of the movable platform is rotatably connected to the horizontal slide plate through a longitudinal rotating shaft. A left eccentric shaft is provided on one side of the longitudinal rotating shaft, and a right eccentric shaft is provided on the other side. The left and right eccentric shafts are rotatably connected to the horizontal slide plate, and the left and right eccentric shafts support the lower surface of the movable platform. The left and right eccentric shafts are driven to rotate by motors.

[0007] As a preferred embodiment of the above technical solution, the clamp is mounted on the longitudinal slide plate, a longitudinal slider is fixedly connected to the longitudinal slide plate, the longitudinal slider is slidably mounted on the longitudinal slide rail, and the longitudinal movement drive mechanism drives the longitudinal slider to move longitudinally on the longitudinal slide rail.

[0008] As a preferred embodiment of the above technical solution, a mechanical gripper is installed on the longitudinal slide plate. The mechanical gripper is driven to move up and down by a second lifting drive mechanism and to rotate by a second rotating drive mechanism.

[0009] As a preferred embodiment of the above technical solution, the machining tool includes a drilling bit, a chamfering tool, or a polishing disc.

[0010] The copper busbar machining method, using the aforementioned copper busbar machining device, includes the following steps: 1) Place a copper plate of a certain size on the moving platform, and use the moving drive mechanism to drive the clamping plate to move and clamp the copper plate. 2) The transverse drive mechanism drives the moving stage to move laterally to the designated position, and the longitudinal drive mechanism drives the chuck to move longitudinally to the designated position, so that the machining tool on the chuck points to the designated position on the copper plate. 3) The rotary drive mechanism drives the chuck to rotate, which in turn drives the machining tool to rotate; the lifting drive mechanism drives the chuck to move downward, which in turn drives the machining tool to descend. The machining tool contacts the copper plate for machining. At this time, according to the machining process requirements, the moving stage moves laterally or remains stationary, the chuck moves longitudinally or remains stationary, and the left and right eccentric shafts rotate to drive the moving stage to rotate at a certain angle or the moving stage remains stationary. 4) Repeat steps 2) and 3) to complete the machining of one side of the copper plate. Then, the clamping plate is released from the copper plate, and the copper plate is turned over to machine the other side until the copper busbar is machined. 5) Take out the machined copper busbar and transfer it to the bending equipment for bending and shaping to obtain the finished copper busbar.

[0011] As a preferred embodiment of the above technical solution, in step 3), after drilling the copper plate with a drill bit, a mechanical gripper is used to take the anti-deformation plug and insert it into the drill hole on the copper plate.

[0012] As a preferred embodiment of the above technical solution, a conveyor belt is provided on one side below the longitudinal slide rail, and several anti-deformation plugs are placed on the conveyor belt. A tool holder is provided on the other side below the longitudinal slide rail, and processing tools are placed on the tool holder.

[0013] The beneficial effects of this invention are: 1. This invention integrates lateral movement, longitudinal movement, lifting movement and rotational movement into one unit. Combined with the multi-directional movement of the moving platform, it can complete multiple processing steps such as drilling, chamfering and polishing on one machine, avoiding the loss of precision caused by multiple workpiece transfers and repeated clamping, and significantly improving processing efficiency and processing accuracy.

[0014] 2. The present invention uses clamping plates distributed on both sides or around the movable platform to clamp and position the copper plate. The clamping force is uniform and reliable, and it can adapt to copper plates of different specifications and sizes, effectively preventing the copper plate from shifting or vibrating during processing.

[0015] 3. The present invention simultaneously sets a chuck and a mechanical gripper on the longitudinal slide plate. After drilling is completed, the anti-deformation plug can be inserted into the drill hole immediately, which effectively prevents the copper busbar from deforming at the hole opening due to stress release in the subsequent bending process, and significantly improves the finished product qualification rate.

[0016] 4. By rotating the left and right eccentric shafts in coordination, the present invention enables the moving platform to deflect at a small angle around the longitudinal axis, thereby achieving fine adjustment of the copper plate processing angle, meeting the special requirements of inclined hole processing or inclined surface processing, and expanding the processing capabilities of the equipment.

[0017] 5. The present invention provides a conveyor belt and a tool holder on both sides of the longitudinal slide rail, which realizes the centralized placement and convenient access of processing tools and anti-deformation plugs, further improving the automation level and ease of operation of processing.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] like Figure 1-3 As shown, the copper busbar machining device and copper busbar machining method are described.

[0023] The copper busbar machining device includes a frame, a movable platform 3 mounted on the frame, a clamping and positioning mechanism, and a machining mechanism. The frame is welded from high-strength steel, providing a stable overall structure and a reliable mounting foundation for all components.

[0024] The movable platform 3 is a flat plate structure with a flat upper surface for placing the copper plate 11 to be processed. The movable platform 3 is slidably mounted on the transverse slide rail 2. Specifically, the transverse slide rail 2 consists of two parallel linear guide rails fixedly mounted on the upper surface of the frame. A transverse slider 21 is fitted onto the transverse slide rail 2, and the transverse slider 21 can slide freely along the length of the transverse slide rail 2. A transverse sliding plate 22 is located below the movable platform 3. The transverse sliding plate 22 is a metal plate, and the transverse slider 21 is fixedly connected to the transverse sliding plate 22 by bolts. The movable platform 3 is positioned above the transverse sliding plate 22 and is driven laterally on the transverse slide rail 2 by a transverse movement drive mechanism. The transverse drive mechanism adopts a servo motor and a ball screw pair. The servo motor is fixedly mounted on the frame, and the ball screw is connected to the output shaft of the servo motor through a coupling. The nut of the ball screw is fixedly connected to the transverse slide plate 22. When the servo motor rotates, it drives the screw to rotate, and the rotational motion is converted into linear motion of the transverse slide plate 22 and the moving platform 3 along the transverse slide rail 2 through the nut.

[0025] The lower end of the movable platform 3 is rotatably connected to the transverse slide plate 22 via a longitudinal rotating shaft 31. Specifically, the longitudinal rotating shaft 31 is rotatably connected to the bottom center of the movable platform 3 via a bearing, and both ends of the longitudinal rotating shaft 31 are fixedly connected to the transverse slide plate 22. The axis of the longitudinal rotating shaft 31 is set horizontally, so that the movable platform 3 can rotate relative to the transverse slide plate 22 around the longitudinal rotating shaft 31.

[0026] A left eccentric shaft 32 is provided on one side of the longitudinal rotating shaft 31, and a right eccentric shaft 33 is provided on the other side. The left eccentric shaft 32 and the right eccentric shaft 33 are rotatably connected to the transverse sliding plate 22 via bearings. The upper ends of the left eccentric shaft 32 and the right eccentric shaft 33 are respectively provided with support surfaces, which abut against the lower surface of the movable platform 3 to support the movable platform 3. The left eccentric shaft 32 is driven to rotate by a first motor, and the right eccentric shaft 33 is driven to rotate by a second motor. Both the first motor and the second motor are stepper motors, fixedly mounted on the transverse sliding plate 22, and their output shafts are connected to the lower ends of the left eccentric shaft 32 and the right eccentric shaft 33 via gear transmission or synchronous belt transmission, respectively. When the first motor and the second motor drive the left eccentric shaft 32 and the right eccentric shaft 33 to rotate respectively, the height of the upper support surfaces of the left eccentric shaft 32 and the right eccentric shaft 33 will change due to the eccentric effect of the eccentric shafts. The left eccentric shaft 32 and the right eccentric shaft 33 will cooperate with a certain rotation angle to form a support angle with one high and one low, so that the moving platform 3 will tilt at a certain angle. With this structure, the processing angle of the copper plate 11 placed on the moving platform 3 can be precisely adjusted to meet the processing requirements of inclined holes, chamfers on both sides, and bevels. Of course, it is also possible to install the longitudinal rotating shaft 31 on one side of the lower end of the moving platform 3, and install another eccentric shaft on the other side to support the moving platform 3. In this way, only one eccentric shaft needs to be driven to rotate to adjust the angle of the moving platform 3. However, the stability of the moving platform 3 is poor in this solution.

[0027] The clamping and positioning mechanism includes several clamping plates 4 disposed above the movable platform 3. In this embodiment, two clamping plates 4 are provided, located at opposite ends of the movable platform 3. The clamping plates 4 are made of steel, and their surfaces facing the center of the movable platform 3 have anti-slip textures to increase friction with the copper plate 11. Each clamping plate 4 is driven by a corresponding moving drive mechanism 41, enabling it to move either towards or away from the center of the movable platform 3. The moving drive mechanism 41 is a cylinder or hydraulic cylinder, fixedly installed at the edge of the movable platform 3, with its piston rod end fixedly connected to the corresponding clamping plate 4. When the piston rod of the moving drive mechanism 41 extends, it drives the clamping plate 4 to move towards the center of the movable platform 3, thereby clamping the copper plate 11 placed on the movable platform 3; when the piston rod retracts, the clamping plate 4 moves away from the center of the movable platform 3, thereby releasing the copper plate 11. The two clamping plates 4 can move synchronously or independently to accommodate copper plates 11 of different shapes and sizes, ensuring that the copper plates 11 are firmly clamped on the moving platform 3 and preventing displacement during processing.

[0028] The processing mechanism includes a chuck 6, a rotary drive mechanism 61, a lifting drive mechanism 62, and a longitudinal drive mechanism.

[0029] The collet 6 is a commonly used spring collet or hydraulic collet, used to securely mount the machining tool 8. The machining tool 8, depending on the machining needs, can be any of the traditional machining tools such as drill bits, chamfering tools, or polishing discs. All of these tools have standard tool holders that mate with the collet 6, allowing for quick clamping and replacement. The collet 6 is mounted on a longitudinal slide plate 52, which is a vertically oriented metal plate. A longitudinal slider is fixedly connected to the longitudinal slide plate 52, and the longitudinal slider is slidably mounted on a longitudinal guide rail 5. The longitudinal guide rail 5 is fixedly mounted on the machine frame. The fit between the longitudinal slider and the longitudinal guide rail 5 uses a precision linear guide pair to ensure smooth sliding and high accuracy.

[0030] The longitudinal drive mechanism drives the longitudinal slider to move longitudinally on the longitudinal slide rail 5. The longitudinal drive mechanism adopts a structure of servo motor and ball screw pair. The servo motor is fixedly mounted on the frame, the ball screw is connected to the output shaft of the servo motor, and the nut of the ball screw is fixedly connected to the longitudinal slide plate 52. When the servo motor rotates, it drives the longitudinal slide plate 52 and the chuck 6 on it to move longitudinally along the longitudinal slide rail 5 through the ball screw and nut pair.

[0031] The rotary drive mechanism 61 is a servo motor or a pneumatic motor. Its output shaft is connected to the chuck 6 via a synchronous belt drive or a direct connection. It is used to drive the chuck 6 to rotate around its own axis, thereby driving the machining tool 8 mounted on the chuck 6 to rotate, so as to realize cutting or grinding.

[0032] A lifting drive mechanism 62 is mounted on the longitudinal slide plate 52 and is used to drive the chuck 6 to move up and down. In this embodiment, the lifting drive mechanism 62 is a cylinder or a linear motor, with its fixed end mounted on the longitudinal slide plate 52 and its movable end fixedly connected to the rotary drive mechanism 61. When the lifting drive mechanism 62 is activated, it drives the chuck 6 to move up and down vertically, thereby controlling the contact and separation between the machining tool 8 and the surface of the copper plate 11, as well as the feed depth.

[0033] A mechanical gripper 7 is also installed on the longitudinal slide plate 52. The mechanical gripper 7 is a pneumatic or electric gripper with two openable fingers for gripping objects. The mechanical gripper 7 is driven to move up and down by a second lifting drive mechanism 71. The second lifting drive mechanism 71 is a cylinder, fixedly installed on the longitudinal slide plate 52, and its piston rod end is fixedly connected to the mounting base of the second rotary drive mechanism 72. The second rotary drive mechanism 72 is a stepper motor, installed between the movable end of the second lifting drive mechanism 71 and the mechanical gripper 7. The output shaft of the stepper motor is fixedly connected to the body of the mechanical gripper 7, and is used to drive the mechanical gripper 7 to rotate around the vertical axis to adjust the gripping angle and orientation of the mechanical gripper 7.

[0034] A conveyor belt 9 is located on one side below the longitudinal slide rail 5 (i.e., on the frame, to the left or right of the longitudinal slide rail 5). The conveyor belt 9 is a ring-shaped conveyor belt, consisting of a drive roller, a driven roller, and a belt sleeved on the two rollers. The drive roller is driven by a stepper motor, which drives the belt to move in a stepping motion. Several anti-deformation plugs 91 are placed on the conveyor belt 9. The anti-deformation plugs 91 are cylindrical plugs whose outer diameter is adapted to the inner diameter of the hole to be drilled on the copper plate 11 (preferably a transition fit or a slight interference fit), and are made of a material with a certain elasticity and strength, such as nylon, polyurethane, or engineering plastics. After drilling is completed, the mechanical gripper 7 can pick up the anti-deformation plugs 91 from the conveyor belt 9 and insert them into the drilled hole to support the hole wall and prevent the hole opening from deforming during the subsequent bending process.

[0035] On the other side below the longitudinal slide rail 5 (i.e., the opposite side of the frame located to the right or left of the longitudinal slide rail 5), there is a tool holder 10. The tool holder 10 is a frame with multiple slots or placement holes, and several different machining tools 8 are placed on the tool holder 10, including drilling bits, chamfering tools, and polishing discs. The machining tools 8 are arranged longitudinally on the tool holder 10. When it is necessary to change the tool, the chuck 6 moves to the position of the tool holder 10, and the current tool is unloaded and replaced with the required tool by automatic or manual means.

[0036] In addition, this device also includes a control unit (not shown in the figure). The control unit adopts a programmable logic controller (PLC) or an industrial computer, and is electrically connected to the transverse drive mechanism, the moving drive mechanism 41, the rotary drive mechanism 61, the lifting drive mechanism 62, the longitudinal drive mechanism, the first motor, the second motor, the second lifting drive mechanism 71, the second rotary drive mechanism 72, and the stepper motor of the conveyor belt 9, respectively. It is used to store the processing program and control the action sequence, movement speed, and movement position of the above-mentioned mechanisms according to the preset processing technology. The control unit is also equipped with a touch screen operation panel for operators to input processing parameters, select processing modes, and monitor processing status.

[0037] The copper busbar machining method provided by the present invention will be described in detail below with reference to the structure of the copper busbar machining apparatus described above. The method includes the following steps: Step 1): Place a copper plate 11 of a certain size on the upper surface of the movable platform 3. According to the size and shape of the copper plate 11, activate the corresponding moving drive mechanism 41 through the control unit. Drive the clamping plates 4 distributed on both sides of the movable platform 3 to move synchronously towards the center of the movable platform 3 until the inner sides of the clamping plates 4 are tightly pressed against both ends of the copper plate 11, firmly clamping the copper plate 11 onto the movable platform 3. The clamping force can be controlled by adjusting the air pressure or oil pressure of the moving drive mechanism 41 to avoid excessive clamping force damaging the surface of the copper plate 11 or insufficient clamping force causing the copper plate 11 to loosen.

[0038] Step 2): According to the preset machining program, the transverse drive mechanism drives the moving stage 3 to move laterally along the transverse slide rail 2 to the specified transverse position, while the longitudinal drive mechanism drives the longitudinal slide plate 52 to move longitudinally along the longitudinal slide rail 5 to the specified longitudinal position, so that the projection of the current machining tool 8 mounted on the chuck 6 on the horizontal plane points to the specified position to be machined on the copper plate 11. The transverse movement of the moving stage 3 and the longitudinal movement of the chuck 6 can be performed sequentially or simultaneously to improve positioning efficiency.

[0039] Step 3): The rotary drive mechanism 61 drives the chuck 6 to rotate, causing the machining tool 8 mounted on the chuck 6 to rotate at a preset speed. Simultaneously, the lifting drive mechanism 62 drives the chuck 6 to move vertically downwards, causing the machining tool 8 to descend until it contacts the upper surface of the copper plate 11, at which point machining begins. During machining, according to the machining process requirements, the moving stage 3 moves laterally or remains stationary according to the machining trajectory, while the chuck 6 moves longitudinally or remains stationary according to the machining trajectory. Specifically, when machining straight grooves, the moving stage 3 moves laterally while the chuck 6 remains stationary longitudinally; when machining longitudinal grooves, the chuck 6 moves longitudinally while the moving stage 3 remains stationary laterally; when machining curves or oblique lines, the moving stage 3 and the chuck 6 work in conjunction. When it is necessary to process inclined holes or inclined surfaces, the first motor and / or the second motor are started to drive the left eccentric shaft 32 and / or the right eccentric shaft 33 to rotate, so that the moving stage 3 rotates around the longitudinal axis 31 at a certain angle (usually within ±5°), thereby making the copper plate 11 generate a predetermined angle relative to the feed direction of the processing tool 8, so as to realize the processing of inclined holes or inclined surfaces; when no angle adjustment is required, the left eccentric shaft 32 and the right eccentric shaft 33 remain stationary, and the moving stage 3 remains horizontal.

[0040] In step 3), if the currently used machining tool 8 is a drilling bit, after the drilling operation is completed, the chuck 6 is slightly raised under the drive of the lifting drive mechanism 62 to disengage the drilling bit from the hole. Then, the longitudinal drive mechanism drives the longitudinal slide plate 52 to move to the side where the conveyor belt 9 is located. The second lifting drive mechanism 71 drives the mechanical gripper 7 to descend. The mechanical gripper 7 picks up an anti-deformation plug 91 on the conveyor belt 9. After picking up, the second lifting drive mechanism 71 drives the mechanical gripper 7 to rise. The longitudinal drive mechanism then drives the longitudinal slide plate 52 to move back to the drilling position. The second lifting drive mechanism 71 drives the mechanical gripper 7 to descend and align the anti-deformation plug 91 with the drilling hole. The second rotation drive mechanism 72 drives the mechanical gripper 7 to rotate at an appropriate angle as needed to adjust the insertion direction. Finally, the anti-deformation plug 91 is pressed into the hole on the copper plate 11. After the anti-deformation plug 91 is inserted, its outer wall fits tightly against the inner wall of the drilling hole, thereby providing effective support for the hole wall.

[0041] Step 4): Repeat steps 2) and 3) above, and perform drilling, chamfering, polishing, and other machining operations on all the locations to be machined on the copper plate 11 according to the preset processing sequence. When it is necessary to change the tool, the chuck 6 moves to the tool holder 10 position, and the current tool is unloaded and replaced with the next required tool by manual or automatic means. After completing all the machining processes on the current upper surface of the copper plate 11, the control unit controls the moving drive mechanism 41 to drive the clamping plate 4 to release the copper plate 11, and the operator flips the copper plate 11 to the other side (i.e., the lower surface is facing up), and clamps and machines the other side of the copper plate 11 again in the manner of steps 1) to 3) until all sides of the copper plate 11 have completed the set machining operations, and a machined copper busbar semi-finished product is obtained. It should be noted that if the copper plate 11 only needs to be machined on one side, there is no need to perform the flipping operation.

[0042] Step 5): Remove the machined copper busbar semi-finished product from the movable platform 3 and transfer it to the bending equipment. Bend and shape it according to the preset bending angle and position. Since anti-deformation plugs 91 are inserted into the drilled holes on the copper busbar, the hole walls are effectively supported during the bending process, preventing shrinkage, out-of-roundness, or deformation due to bending stress. After bending, a finished copper busbar meeting the size and shape requirements is obtained. The anti-deformation plugs 91 can be removed from the drilled holes after bending, or they can be retained in the product, depending on customer requirements.

[0043] All motion parameters, position coordinates, feed rate, spindle speed, and machining sequence in the above machining process are pre-programmed and stored in the control unit. During machining, the control unit automatically calls and executes the program, and the operator only needs to start the machining process through the touch screen, which greatly reduces manual intervention and operation difficulty.

[0044] It is worth mentioning that the technical features such as motors and machining tools involved in this patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field, and should not be regarded as the inventive point of this patent. This patent will not be further elaborated in detail.

[0045] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
