Description

Technical Field

[0001] This utility model relates to the field of battery swapping cabinet back panel processing technology, and in particular to a device for punching heat dissipation holes in the back panel of a battery swapping cabinet. Background Technology

[0002] The back panel of the battery swapping cabinet is a key plate-shaped structural component that is fixedly connected to the back of the cabinet and the frame, forming a closed support system. It provides an installation base for internal components such as the battery compartment through its own rigidity and enhances the cabinet's resistance to deformation. It also blocks dust and rainwater, reduces electromagnetic radiation, and often has pre-set cable trays and wiring holes to facilitate neat wiring. It is usually made of cold-rolled steel plate, aluminum alloy plate or composite material, and its size matches the cabinet frame. The material should be selected based on the usage scenario, load-bearing and protection requirements. It is an important part of ensuring the structural stability and safe operation of the battery swapping cabinet.

[0003] During production, the back panel of a battery swapping cabinet typically requires ventilation holes to ensure effective heat dissipation. However, traditional punching devices on the market require the back panel to be installed below the punching head to achieve the punching effect. This process necessitates manual installation of the back panel into the punching area during loading and unloading. This process requires the installer's hands to be close to the punching area. Although some devices are equipped with simple protective railings, there is still a risk of pinching and scratching, reducing safety during use. Furthermore, the waste generated during punching usually falls directly below the punching area, requiring regular manual cleaning to prevent clogging of the mold's through holes. This process can also easily injure cleaning personnel, and stopping the machine for cleaning reduces punching efficiency.

[0004] Therefore, this application provides a punching device for heat dissipation holes on the back panel of a battery swapping cabinet to meet the requirements. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose a punching device for heat dissipation holes on the back panel of a battery swapping cabinet.

[0006] The technical problem to be solved by this utility model is to provide a punching device for heat dissipation holes on the back panel of a battery swapping cabinet to solve the existing problems.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: It includes a stamping table, a stamping frame, a hydraulic cylinder, a stamping head, and a forming mold. Adjustment grooves are provided on both sides of the upper surface of the stamping table. A support frame for safe material feeding is slidably provided on the upper surface of the adjustment grooves. The stamping table is located inside the support frame, and a fixing seat for fixing the forming mold is fixedly connected to its upper surface. A feeding channel is provided laterally inside the inner cavity of the stamping table below the fixing seat. A pusher plate for pushing waste material is slidably provided on one side of the inner cavity of the feeding channel. A driving assembly for synchronously moving the support frame and the pusher plate is provided on one side of the stamping table. A waste collection assembly for waste material recycling is slidably provided inside the stamping table below the feeding channel.

[0008] Preferably, the drive assembly includes a motor base, a servo motor, a pulley, an adjusting screw, an adjusting groove, and a transmission screw. The adjusting groove has adjusting screws rotatably mounted on both sides of its inner cavity. The stamping table has motor bases fixedly connected to both sides of the stamping table at positions corresponding to the adjusting screws. The servo motor is fixedly connected to the outer wall of the motor base, and the power output end of the servo motor is fixedly connected to one end of the adjusting screw at the corresponding position.

[0009] Preferably, the inner cavity of the feeding channel is provided with a transmission screw that rotates laterally, and the pusher plate is threadedly connected to the surface of the transmission screw through a threaded hole provided in the main body. A pulley is provided on the surface of the stamping table at one end of the transmission screw and on the same side as the servo motor. A transmission belt is fitted on the surface of the pulley, and the other side of the transmission belt is fitted into the inner cavity of the belt groove provided in the power output end of the servo motor.

[0010] Preferably, the waste collection assembly includes a nested frame, a collection frame, a gravity sensor, and a carrying slot. The nested frame is slidably disposed on one side inside the stamping table. The collection frame is nested inside the nested frame. The gravity sensor is detachably connected to the surface of the nested frame below the collection frame. Carrying slots are provided on the upper ends of both sides of the inner cavity of the collection frame.

[0011] Preferably, the stamping frame is fixedly connected to the upper surface of the stamping platform, and the stamping frame is located above the fixed base. A warning light is provided on one side of the top of the stamping frame, and the warning light is electrically connected to the gravity sensor through a wire.

[0012] Preferably, the upper surface of the support frame is provided with a grid-type vacuum suction cup for fixing when punching holes in the back panel of the battery swapping cabinet, and a connecting pipe is interconnected on one side of the grid-type vacuum suction cup.

[0013] Preferably, the stamping table has negative pressure chambers on both sides of one end, and the end of the connecting pipe is interconnected with a vacuum pump installed in the cavity of the negative pressure chamber.

[0014] Preferably, a hydraulic cylinder is detachably fixed at the center of the upper surface of the stamping frame, and a stamping head is detachably fixed at the power output end of the hydraulic cylinder, with the stamping head located directly above the fixed seat. The forming mold is detachably nested inside the upper part of the fixed seat, and the bottom end of the fixed seat is interconnected with the feeding channel.

[0015] In the above solution, during loading and unloading, the servo motor drives the adjusting screw to rotate counterclockwise, which in turn drives the bearing fixing frame to slide outward from the stamping area along the adjusting groove. During loading and unloading, the bearing fixing frame can be completely moved out of the punching area formed by the stamping head and the forming mold, avoiding the risk of pinching injuries when manually loading and unloading. At the same time, the servo motor drives the adjusting screw and the transmission screw to rotate synchronously through the pulley and the transmission belt, and then the pusher plate moves outward in the feeding channel. The pusher plate can automatically push the waste generated by punching into the waste collection component along the feeding channel, eliminating the need for manual cleaning of waste and realizing automatic waste collection. This avoids waste accumulation and blockage of the discharge hole, ensuring stable waste discharge during stamping, effectively improving the stability of stamping, and ensuring the quality of the punching of the heat dissipation holes on the battery swapping back panel. In the above solution, the weight of the waste in the collection box can be detected in real time by a gravity sensor installed at the bottom of the nested frame cavity. When the weight of the waste reaches the preset threshold, the gravity sensor triggers the warning light on the stamping frame through the wire, which intuitively prompts the staff to clean up the waste in time. There is no need for the staff to frequently check the overflow of the collection box. This avoids the interruption of processing due to the accumulation of waste blocking the feeding channel, and ensures that the waste collection process is orderly and efficient. It also ensures the continuity of the punching process of the battery swapping cabinet back panel, and improves the overall production efficiency and practical effect. Attached Figure Description

[0022] Please see Figure 1 - Figure 4A punching device for heat dissipation holes on the back panel of a battery swapping cabinet includes a punching table 1, a punching frame 6, a hydraulic cylinder 7, a punching head 9, and a forming mold 11. Adjustment grooves 125 are provided on both sides of the upper surface of the punching table 1. A support frame 2 for safe feeding is slidably mounted on the upper surface of the adjustment grooves 125. The punching table 1 is located inside the support frame 2, and a fixing seat 10 for fixing the forming mold 11 is fixedly connected to its upper surface. A feeding channel 128 is provided laterally in the inner cavity of the punching table 1 below the fixing seat 10. A pusher plate 127 for pushing waste material is slidably mounted on one side of the inner cavity of the feeding channel 128. A drive assembly 1 is provided on one side of the punching table 1 for driving the support frame 2 and the pusher plate 127 to move synchronously. 2. A waste collection component 13 for waste recycling is slidably installed inside the stamping table 1 located below one side of the feeding channel 128. The bearing fixing frame 2 is slidably set through the adjusting groove 125 of the stamping table 1. With the help of the drive component 12, the bearing fixing frame 2 and the push plate 127 can move synchronously. This can not only move the bearing fixing frame 2 out of the punching area to ensure operational safety when feeding, but also push the waste to the waste collection component 13 synchronously after processing. At the same time, the forming mold 11 is stably fixed by the fixed seat 10, and the hydraulic cylinder 7 drives the stamping head 9 to punch accurately. The overall structure realizes the integration of safe feeding, accurate forming and automatic waste collection in the punching process of the battery swapping cabinet back panel, effectively improving processing efficiency and operation convenience.

[0023] Please see Figure 2 and Figure 3 The drive assembly 12 includes a motor base 121, a servo motor 122, a pulley 123, an adjusting screw 124, an adjusting groove 125, and a transmission screw 126. Adjusting screws 124 are laterally rotatable on both sides of the inner cavity of the adjusting groove 125. Motor bases 121 are fixedly connected to both sides of the stamping table 1 at positions corresponding to the adjusting screws 124. A servo motor 122 is fixedly connected to the outer wall of the motor base 121, and the power output end of the servo motor 122 is fixedly connected to one end of the adjusting screw 124 at the corresponding position. A transmission screw 126 is laterally rotatable within the inner cavity of the feeding channel 128, and the pusher plate 127 is threadedly connected to the surface of the transmission screw 126 through a threaded hole provided in the main body. A pulley 123 is rotatably mounted on the surface of the stamping table 1 on one end of the 26 and the same side as the servo motor 122. A transmission belt 129 is fitted on the surface of the pulley 123, and the other side of the transmission belt 129 is fitted into the belt groove cavity that is matched with the power output end of the servo motor 122. The servo motor 122 synchronously drives the adjusting screw 124 and the transmission screw 126. The synchronous movement of the two is achieved by the transmission cooperation of the pulley 123 and the transmission belt 129. This ensures that the support frame 2 moves accurately and ensures the centering when punching the back panel of the battery swapping cabinet. It can also push the waste material synchronously when loading and unloading. No additional drive components are required. The operation is convenient, the processing efficiency is improved, and the equipment manufacturing cost and maintenance difficulty are reduced.

[0024] Please see Figure 1 and Figure 4 The waste recycling assembly includes a nested frame 131, a collection frame 132, a gravity sensor 133, and a carrying slot 134. The nested frame 131 is slidably disposed inside one side of the stamping table 1. The collection frame 132 is nested inside the nested frame 131. The gravity sensor 133 is detachably connected to the surface of the nested frame 131 below the collection frame 132. Carrying slots 134 are provided on the upper ends of both sides of the inner cavity of the collection frame 132. The stamping frame 6 is fixedly connected to the upper surface of the stamping table 1, and the stamping frame 6 is located above the fixed base 10. A warning light 8 is provided on one side of the top of the pressing frame 6, and the warning light 8 is electrically connected to the gravity sensor 133 through a wire. The weight of the waste material can be monitored in real time by the gravity sensor 133 below the collection frame 132. When the weight reaches the preset threshold, the warning light 8 on the pressing frame 6 is triggered by the wire. There is no need for frequent manual checks on the collection status. This avoids the accumulation of waste material blocking the feeding channel 128 and causing processing interruption, and ensures timely and efficient waste material cleaning. It also ensures the continuity of the punching process of the battery swapping cabinet back panel and effectively improves the punching efficiency.

[0025] Please see Figure 1 The upper surface of the support frame 2 is equipped with a grid-type vacuum suction cup 3 for fixing the back panel of the battery swapping cabinet during punching. The grid-type vacuum suction cup 3 is connected to a connecting pipe 4 on one side. Negative pressure chambers 5 are provided on both sides of one end of the punching table 1, and the end of the connecting pipe 4 is connected to a vacuum pump installed in the inner cavity of the negative pressure chamber 5. The grid-type vacuum suction cup 3 on the upper surface of the support frame 2 is connected to the vacuum pump of the negative pressure chamber 5 of the punching table 1 through the connecting pipe 4, which can form a uniformly distributed negative pressure adsorption force, which can tightly fix the back panel of the battery swapping cabinet of different sizes and materials, and prevent the back panel from moving due to local stress during punching, thus ensuring the quality of punching.

[0026] Please see Figure 1 A hydraulic cylinder 7 is detachably fixed at the center of the upper surface of the stamping frame 6. A stamping head 9 is detachably fixed at the power output end of the hydraulic cylinder 7, and the stamping head 9 is located directly above the fixed base 10. The forming mold 11 is detachably nested inside the upper end of the fixed base 10, and the bottom end of the fixed base 10 is interconnected with the feeding channel 128. The hydraulic cylinder 7 drives the stamping head 9 to move up and down, and together with the forming mold 11 directly below, it can accurately and effectively punch holes in the back panel of the battery swapping cabinet. During punching, the design of the bottom end of the fixed base 10 being interconnected with the feeding channel 128 allows the punching waste to fall directly into the channel, avoiding the accumulation of waste that affects processing accuracy and efficiency.

[0027] Working principle: First, the servo motor 122 drives the adjusting screw 124 to rotate counterclockwise, so that the bearing fixing frame 2 slides outward along the adjusting groove 125 from the punching area formed by the punching head 9 and the forming mold 11, so that it is completely moved out of the dangerous work position. At this time, the worker places the back panel of the battery swapping cabinet to be processed on the upper surface of the bearing fixing frame 2, starts the vacuum pump of the negative pressure chamber 5, and uses the grid-type vacuum suction cup 3 to tightly adsorb and fix the back panel. Then, the servo motor 122 is controlled to rotate clockwise, driving the adjusting screw 124 to reset the bearing fixing frame 2 to the top of the fixing seat 10, so that the punching position of the heat dissipation hole of the back plate is aligned with the forming mold 11. At the same time, the servo motor 122 drives the transmission screw 126 in the feeding channel 128 to rotate synchronously through the pulley 123 and the transmission belt 129, so that the pusher plate 127 moves inward along the feeding channel 128 to the initial position. Hydraulic cylinder 7 is activated, and its power output end drives the punch head 9 to move downwards. This, in conjunction with the forming mold 11 inside the fixed base 10, punches ventilation holes in the back plate. The waste material generated during punching falls through the bottom of the fixed base 10 into the feeding channel 128. After processing, hydraulic cylinder 7 drives the punch head 9 to reset, and then controls the servo motor 122 to rotate counterclockwise. This moves the supporting frame 2 out of the punching area so that the worker can remove the processed back plate. Simultaneously, it drives the transmission screw 126 to move the pusher plate 127 outwards along the feeding channel 128, automatically pushing the waste material in the feeding channel 128 to the waste collection point. In the collection frame 132 of the assembly 13, the gravity sensor 133 on the surface of the nested frame 131 simultaneously detects the weight of the waste material inside the collection frame 132 in real time. When the weight reaches a preset threshold, the gravity sensor 133 triggers the warning light 8 on the stamping frame 6 through the wire, prompting the operator to pull out the collection frame 132 through the handle 134 to clean up the waste material. After cleaning, the collection frame 132 is nested back into the nested frame 131, the gravity sensor 133 is reset, the warning light 8 is turned off, and the device continues to enter the next processing cycle, ensuring that the entire punching process is safe, automated, continuous and efficient, effectively improving punching efficiency and quality.
