Description

Technical Field

[0001] This invention relates to the field of automatic polishing technology, specifically to a battery casing polishing device with dust removal function. Background Technology

[0002] The battery casing is one of the important components of a battery. It contains the electrode fluid and plates and is mostly made of acid-resistant and heat-resistant materials. The quality requirements for the battery casing are also relatively high during the production process.

[0003] To ensure the lifespan of the battery casing, it needs to be polished during production. This removes surface imperfections such as scratches and improves the casing's appearance. However, due to the varying surface quality of battery casings, conventional polishing equipment can only perform constant-power polishing, meaning the polishing speed and time remain fixed. It cannot automatically adjust the polishing time based on the depth of protrusions on the battery casing surface. This results in inconsistent polishing quality for areas with large protrusions, while wasting energy on areas with small protrusions, thus reducing polishing efficiency.

[0004] In addition, due to the varying heat dissipation power required by different parts of the battery casing during the polishing process, local heat accumulation can easily occur, affecting the polishing quality. Summary of the Invention

[0005] The purpose of this invention is to provide a battery casing polishing device with dust removal function to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a battery casing polishing device with dust removal function.

[0007] A battery casing polishing device with dust removal function includes a support device, a drive device, a dust collection device, a temperature control device, and a conveyor belt. The conveyor belt is connected to the support device, and a plurality of platforms are provided on the outer ring of the conveyor belt for mounting the battery casing. The drive device is connected to the support device, the drive device is connected to the dust collection device, and the temperature control device is connected to the dust collection device.

[0008] The support device serves as the main support foundation for installing and fixing other devices. The drive device serves as the main power source, providing power for the grinding process. During the grinding of the battery casing, the dust collection device automatically collects the debris to prevent it from dispersing into the air. When grinding uneven surfaces of the battery casing, the amount of debris generated varies. The temperature control device provides localized controlled heat dissipation to keep the grinding process stable. The conveyor belt uses a rotary mechanism, driven by a drive motor that drives the rollers, thereby causing the conveyor belt to rotate. The platform transports the battery casing to the grinding station for grinding.

[0009] Furthermore, the support device includes a base, a truss, and a support frame. The base is provided with a cross module, which provides horizontal "+" linear displacement. The output end of the cross module is connected to the truss via a drive. The truss is provided with a drive cavity, and a vertical module is provided inside the drive cavity. The output end of the vertical module is fastened to the support frame, and the support frame is connected to the drive device via a drive.

[0010] The cross module is a combination of two modules arranged together. Like the vertical module, it adopts the existing module form and provides linear displacement. The cross module provides two linear positions in the horizontal direction, while the vertical module provides linear displacement in the vertical direction, thereby providing a spatial displacement state for the drive device. This allows it to adapt to the grinding of battery casings of different specifications. In order to ensure the grinding efficiency of the battery casing, a robotic arm is installed on one side of the conveyor belt to flip the battery casing so that the surface to be ground always faces the grinding device.

[0011] Furthermore, the drive device includes a grinding motor and a grinding head. The grinding motor is fastened to the truss. The output end of the grinding motor is inserted into the drive cavity. A transmission shaft is provided between the grinding motor and the grinding head. The transmission shaft is rotatably connected to the drive cavity. The transmission shaft includes a base shaft and a movable shaft. The grinding motor is drivenly connected to the base shaft. The upper end of the base shaft is rotatably connected to the transmission cavity. A limiting groove is provided on the base shaft. The upper end of the movable shaft is engaged with the limiting groove. The movable shaft is rotatably connected to the support frame. The lower end of the movable shaft is drivenly connected to the grinding head. The grinding surface of the grinding head is arranged vertically.

[0012] During vertical movement: the movable shaft and the limiting groove are slidably connected.

[0013] The grinding motor is fixed on the truss. The displacement output by the cross module is transmitted to the support frame through the truss transmission. The vertical module is placed in the drive cavity of the truss, and its output end drives the support frame to move vertically, thereby moving the grinding head. The torque output by the grinding motor is transmitted to the drive shaft through transmission. The transmission method can be a pulley or conveyor belt transmission, which is existing technology and will not be described in detail. The drive shaft adopts a split structure design, with the base shaft located at the upper end and rotated and supported by the drive cavity. The limiting groove of the base shaft can be arranged in the form of a keyway. During the rotation of the base shaft, it can drive the movable shaft to rotate without restricting the axial displacement of the movable shaft. This ensures that it can automatically adjust when grinding different heights of the side surface of the battery casing, adapting to the grinding of battery casings of various sizes.

[0014] Furthermore, the dust collection device is connected to the support frame. The dust collection device includes an exhaust pipe and a cover. The cover is provided with a dust suction chamber. The grinding head is placed in the dust suction chamber. The cover and the support frame are fastened together. The cover is opened on the side facing the battery casing. A dust collection channel is provided on one side of the dust suction chamber. One end of the exhaust pipe is connected to a negative pressure air source, and the other end is connected to the dust collection channel pipe.

[0015] The dust collection channel is arranged along the direction of the flying debris from the grinding head.

[0016] The dust collection device is mounted on a support frame for easy movement along with the grinding head. The exhaust pipe is connected to the negative pressure air source, thereby creating negative pressure in the dust collection channel. The dust collection channel is connected to the dust suction chamber and is arranged along the direction of the grinding debris splashing from the grinding head, improving the debris collection efficiency. At the same time, the air flow cools the local area of ​​the battery casing being ground, ensuring grinding quality. Through pressure difference diversion, the grinding debris is diverted through the dust suction chamber into the dust collection channel. The dust suction chamber on the cover is mainly used to provide working space for grinding and prevent debris from flying out and affecting the safety of the operator.

[0017] Furthermore, the temperature control device includes a temperature sensing component. A detection chamber is provided on one side of the dust collection channel. The temperature sensing component is placed in the detection chamber. The temperature sensing component includes a transmission plate, a magnetic rod, and a coil. The transmission plate and the detection chamber are rotatably connected. One end of the transmission plate extends into the dust collection channel. The rotation axis of the transmission plate is arranged vertically. One side of the transmission plate is fastened to the magnetic rod. The coil is placed in the detection chamber.

[0018] The transmission plate includes a rotating plate and a sliding plate. The rotating plate is rotatably connected to the detection chamber. The end of the rotating plate is fastened to the magnetic rod. A slope is provided on one side of the detection chamber. The slope is located on the side close to the dust collection channel inlet. A sliding groove is provided on the rotating plate. The upper end of the sliding plate is slidably connected to the sliding groove of the rotating plate, and the lower end of the sliding plate is slidably connected to the slope.

[0019] The heat generated instantaneously during polishing is indirectly measured by a built-in temperature sensing component in the detection chamber. During polishing, polishing debris is carried by airflow into the dust collection channel and impacts the transmission plate, causing it to rotate. As the transmission plate rotates, a magnetic rod is inserted into the coil. The magnetic rod is made of magnet material, and the coil cuts magnetic field lines, generating an induced current. When the thickness of the battery casing to be polished increases in a certain area, more debris particles enter the dust collection channel, increasing the amount of gas entrainment and thus increasing the rotation angle of the transmission plate, resulting in a larger induced current. The transmission plate is a split design. When the plate rotates, it causes a sliding plate to move up the slope of the detection chamber. The sliding plate slides upward within a groove on the plate. As polishing progresses, the surface of the battery casing gradually reaches the standard, reducing the amount of debris entering the dust collection channel. The sliding plate then slides down the slope under gravity, causing the plate to rotate and automatically reset, thus enabling real-time detection of the polishing quality of the battery casing surface. The side of the dust collection channel closest to the battery casing is the inner side, and the detection chamber is located on the outer side of the dust collection channel.

[0020] Furthermore, the temperature control device also includes an adjustment component. The cover is provided with an adjustment groove, and the adjustment component is placed in the adjustment groove. The dust collection channel divides the adjustment groove into two sections. The adjustment component includes a current-raising plate and a current-raising electromagnet. The current-raising electromagnet is placed in the lower section of the adjustment groove, and the current-raising plate is placed in the upper section of the adjustment groove. The current-raising plate is made of magnetic material, and the opposite ends of the current-raising plate and the current-raising electromagnet are the same magnetic poles.

[0021] In the initial state, there is a flow channel between the current booster plate and the current booster electromagnet. The size of the flow channel is designed according to the required wind force. When the thickness of the battery casing to be polished increases, the instantaneous heat generated increases. By adjusting the current input to the current booster electromagnet, the current booster plate moves upward along the adjustment groove under the action of repulsion, expanding the cross-sectional area of ​​the flow channel, thereby increasing the airflow velocity near the polishing head. The heat dissipation effect is automatically adjusted according to different battery casing thicknesses, thereby ensuring polishing efficiency.

[0022] As an optimization, the roughness of the upper section of the adjustment groove gradually increases from bottom to top. The vertical force on the riser plate is its own gravity, the repulsive force of the riser electromagnet, and the frictional resistance of the adjustment groove wall. Based on the current signal detected by the coil, the riser plate is controlled to move upward. As grinding progresses, the number of incoming debris particles decreases. When the current on the coil decreases, the magnetic pole repulsive force provided by the riser electromagnet decreases, and the riser plate moves downward under the action of gravity, thus automatically resetting.

[0023] As an optimization, the coil and the current-raising electromagnet are electrically connected. The current signal generated on the coil is sent to the controller, which controls the magnitude of the current input to the current-raising electromagnet, facilitating real-time adjustment.

[0024] As an optimization, a dust collection trough is provided on the lower side of the dust collection duct, located below the rotation stroke of the rotating plate within the dust collection duct. Because the dust collection trough is located below the rotation stroke of the rotating plate, when debris impacts the rotating plate, its kinetic energy is reduced through energy conversion, and it falls into the dust collection trough under the influence of gravity, thus automatically collecting the debris.

[0025] Compared with the prior art, the beneficial effects achieved by this invention are as follows: The dust collection channel and the dust suction chamber are connected and arranged along the direction of the grinding debris splashing from the grinding head, improving debris collection efficiency. Simultaneously, the airflow cools the localized area being ground on the battery casing, ensuring grinding quality. During grinding, the grinding debris is carried by the airflow into the dust collection channel and impacts the transmission plate, causing it to rotate. During this rotation, the magnetic rod, made of magnetic material, inserts into the coil, causing the coil to cut magnetic field lines and generate an induced current. When the battery... As the thickness of the battery casing to be ground increases in certain areas, more debris particles enter the dust collection channel, leading to increased gas entrainment. This causes the transmission plate to rotate at a larger angle, resulting in a greater induced current. The transmission plate is a split design; when the rotating plate rotates, it drives the sliding plate to move up the slope of the detection chamber. The sliding plate slides upward within the groove of the rotating plate. As grinding progresses, the surface of the battery casing gradually reaches the standard, reducing the amount of debris entering the dust collection channel. Under gravity, the sliding plate slides down the slope and drives the rotating plate to rotate, automatically resetting. This allows for real-time detection of the grinding quality of the battery casing surface. The side of the dust collection channel closest to the battery casing is the inner side, and the detection chamber is located on the outer side of the dust collection channel. When the thickness of the battery casing to be ground in certain areas increases, the instantaneous heat generated increases. By adjusting the current input to the current-lifting electromagnet, the current-lifting plate moves upward along the adjustment groove under the action of repulsion, expanding the cross-sectional area of ​​the flow channel and increasing the airflow velocity near the grinding head. The heat dissipation effect is automatically adjusted according to the different thicknesses of the battery casing, thus ensuring grinding efficiency. Attached Figure Description

[0034] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0035] The present invention provides the following technical solution:

[0036] like Figures 1-2 As shown, a battery casing polishing device with dust removal function is disclosed. The polishing device includes a support device 1, a drive device 2, a dust collection device 3, a temperature control device 4, and a conveyor belt 5. The conveyor belt 5 is connected to the support device 1. The outer ring of the conveyor belt 5 is provided with a plurality of platforms 6 for mounting the battery casing. The drive device 2 is connected to the support device 1, the drive device 2 is connected to the dust collection device 3 by transmission, and the temperature control device 4 is connected to the dust collection device 3.

[0037] Support device 1 serves as the main support foundation for installing and fixing other devices. Drive device 2 serves as the main power source for providing power to the grinding process. During the grinding of the battery casing, dust collection device 3 automatically collects debris to prevent it from dispersing in the air. When grinding uneven surfaces of the battery casing, the amount of debris generated varies. Temperature control device 4 provides localized controlled heat dissipation to keep the grinding process stable. Conveyor belt 5 uses a rotary mechanism, driven by a drive motor to rotate the rollers. The battery casing is then transported to the grinding station via platform 6 for grinding.

[0038] like Figures 1-2As shown, the support device 1 includes a base 11, a truss 14, and a support frame 15. A cross module 12 is provided on the base 11. The cross module 12 provides horizontal "+" linear displacement. The output end of the cross module 12 is connected to the truss 14. A drive cavity is provided on the truss 14. A vertical module 13 is provided in the drive cavity. The output end of the vertical module 13 is fastened to the support frame 15. The support frame 15 is connected to the drive device 2.

[0039] The cross module 12 is a combination of two modules arranged together. Like the vertical module 13, it adopts the form of existing modules and provides linear displacement. The cross module 12 provides two linear positions in the horizontal direction, and the vertical module 13 provides linear displacement in the vertical direction, thereby providing a spatial displacement state for the drive device 2, so as to adapt to the grinding of battery shells of different specifications. In order to ensure the grinding efficiency of the battery shell, a robot is installed on one side of the conveyor belt 5 to flip the battery shell so that the surface to be ground always faces the grinding device.

[0040] like Figures 2-3 As shown, the drive device 2 includes a grinding motor 21 and a grinding head 23. The grinding motor 21 is fastened to the truss 14. The output end of the grinding motor 21 is inserted into the drive cavity. A transmission shaft 22 is provided between the grinding motor 21 and the grinding head 23. The transmission shaft 22 is rotatably connected to the drive cavity. The transmission shaft 22 includes a base shaft 221 and a movable shaft 222. The grinding motor 21 is drivenly connected to the base shaft 221. The upper end of the base shaft 221 is rotatably connected to the transmission cavity. A limiting groove is provided on the base shaft 221. The upper end of the movable shaft 222 is engaged with the limiting groove. The movable shaft 222 is rotatably connected to the support frame 15. The lower end of the movable shaft 222 is drivenly connected to the grinding head 23. The grinding surface of the grinding head 23 is arranged vertically.

[0041] During vertical movement: the movable shaft 222 and the limiting groove are slidably connected.

[0042] The grinding motor 21 is fixed on the truss 14. The displacement output by the cross module 12 is transmitted to the support frame 15 through the truss 14. The vertical module 13 is placed in the drive cavity of the truss 14, and its output end drives the support frame 15 to move vertically, thereby driving the grinding head 23 to move. The torque output by the grinding motor 21 is transmitted to the drive shaft 22 through the drive. The transmission method can be a pulley or conveyor belt transmission, which is existing technology and will not be described in detail. The drive shaft 22 adopts a split structure design, with the base shaft 221 located at the upper end and rotated and supported by the drive cavity. The limiting groove of the base shaft 221 can adopt a keyway arrangement. During the rotation of the base shaft 221, it can drive the movable shaft 222 to rotate without restricting the axial displacement of the movable shaft 222. This ensures that it can automatically adjust when grinding different heights of the side surface of the battery casing, adapting to the grinding of battery casings of various specifications.

[0043] like Figures 1-3 As shown, the dust collection device 3 and the support frame 15 are connected. The dust collection device 3 includes an air duct 31 and a cover 32. The cover 32 is provided with a dust suction chamber 321. The grinding head 23 is placed in the dust suction chamber 321. The cover 32 and the support frame 15 are fastened together. The cover 32 is opened on the side facing the battery casing. The dust suction chamber 321 is provided with a dust collection channel 322 on one side. One end of the air duct 31 is connected to a negative pressure air source, and the other end is connected to the dust collection channel 322.

[0044] The dust collection channel 322 is arranged along the direction of the flying debris from the grinding head 23.

[0045] The dust collection device 3 is installed on the support frame 15, which facilitates its movement along with the grinding head 23. The exhaust pipe 31 is connected to the negative pressure air source, thereby creating negative pressure in the dust collection channel 322. The dust collection channel 322 is connected to the dust suction chamber 321 and is arranged along the direction of the grinding debris splashed by the grinding head 23, which improves the debris collection efficiency. At the same time, the air flow cools the local area of ​​the battery casing being ground, ensuring the grinding quality. Through pressure difference diversion, the grinding debris is diverted into the dust collection channel 322 through the dust suction chamber 321. The dust suction chamber 321 set on the cover 32 is mainly used to provide working space for grinding and prevent debris from flying out and affecting the safety of the operator.

[0046] like Figures 3-5 As shown, the temperature control device 4 includes a temperature sensing component 41. A detection chamber 324 is provided on one side of the dust collection channel 322. The temperature sensing component 41 is placed in the detection chamber 324. The temperature sensing component 41 includes a transmission plate 411, a magnetic rod 412 and a coil 413. The transmission plate 411 and the detection chamber 324 are rotatably connected. One end of the transmission plate 411 extends into the dust collection channel 322. The rotation axis of the transmission plate 411 is arranged vertically. One side of the transmission plate 411 is fastened to the magnetic rod 412. The coil 413 is placed in the detection chamber 324.

[0047] The transmission plate 411 includes a rotating plate 4111 and a sliding plate 4112. The rotating plate 4111 is rotatably connected to the detection chamber 324. The end of the rotating plate 4111 is fastened to the magnetic rod 412. A slope is provided on one side of the detection chamber 324. The slope is located near the inlet of the dust collection channel 322. A groove is provided on the rotating plate 4111. The upper end of the sliding plate 4112 is slidably connected to the groove of the rotating plate 4111, and the lower end of the sliding plate 4112 is slidably connected to the slope.

[0048] The heat generated instantaneously during the polishing process is indirectly measured by the built-in temperature sensing component 41 in the detection chamber 324. During polishing, polishing debris is carried by the airflow into the dust collection channel 322 and impacts the transmission plate 411, thereby driving the transmission plate 411 to rotate. During the rotation of the transmission plate 411, the magnetic rod 412 is inserted into the inner side of the coil 413. The magnetic rod is made of magnetic material, and the coil 413 moves by cutting magnetic field lines, generating an induced current. When the thickness of the battery casing to be polished increases in a certain area, the number of debris particles entering the dust collection channel 322 increases, and the amount of debris carried by the gas also increases. This increases the rotation angle of the transmission plate 411, resulting in a greater induced current. The transmission plate 411 is a split design. When the rotating plate 4111 rotates, it drives the sliding plate 4112 to move up along the slope of the detection chamber 324. The sliding plate 4112 slides upward within the groove of the rotating plate 4111. As the grinding progresses, the surface of the battery casing gradually reaches the standard, reducing the amount of debris entering the dust collection channel 322. Under the influence of gravity, the sliding plate 4112 slides down the slope and drives the rotating plate 4111 to rotate, automatically resetting. This allows for real-time detection of the grinding quality of the battery casing surface. The side of the dust collection channel 322 closest to the battery casing is the inner side, and the detection chamber 324 is located on the outer side of the dust collection channel 322.

[0049] like Figure 6 As shown, the temperature control device 4 also includes an adjustment component 42. The cover 32 is provided with an adjustment groove 325. The adjustment component 42 is placed in the adjustment groove 325. The dust collection channel 322 divides the adjustment groove 325 into two sections. The adjustment component 42 includes a current-lifting plate 421 and a current-lifting electromagnet 422. The current-lifting electromagnet 422 is placed in the lower section of the adjustment groove 325, and the current-lifting plate 421 is placed in the upper section of the adjustment groove 325. The current-lifting plate 421 is made of magnetic material, and the opposite ends of the current-lifting plate 421 and the current-lifting electromagnet 422 are the same magnetic poles.

[0050] In the initial state, a flow channel is provided between the current booster plate 421 and the current booster electromagnet 422. The size of the flow channel is designed according to the required wind force. When the thickness of the battery casing to be polished increases, the instantaneous heat generated increases. By adjusting the current input to the current booster electromagnet 422, the current booster plate 421 moves upward along the adjustment groove 325 under the action of repulsion, expanding the cross-sectional area of ​​the flow channel, thereby increasing the air flow rate near the polishing head 23. The heat dissipation effect is automatically adjusted according to different battery casing thicknesses, thereby ensuring polishing efficiency.

[0051] As an optimization, the roughness of the upper section of the adjusting groove 325 gradually increases from bottom to top. The vertical force on the lifting plate 421 is its own gravity, the repulsive force of the lifting electromagnet 422, and the frictional resistance of the wall of the adjusting groove 325. Based on the current signal detected by the coil 413, the lifting plate 421 is controlled to move upward. As the grinding proceeds, the number of incoming debris particles decreases. When the current on the coil 413 decreases, the magnetic pole repulsive force provided by the lifting electromagnet 422 decreases, and the lifting plate 421 moves downward under the action of gravity, thus automatically resetting.

[0052] As an optimization, coil 413 and current-boosting electromagnet 422 are electrically connected. The current signal generated on coil 413 is sent to the controller, which controls the magnitude of the current input to current-boosting electromagnet 422 for real-time adjustment.

[0053] As an optimization, a dust collection trough 323 is provided on the lower side of the dust collection duct 322. The dust collection trough 323 is located below the rotation stroke of the rotating plate 4111 within the dust collection duct 322. Since the dust collection trough is located below the rotation stroke of the rotating plate 4111, when debris hits the rotating plate 4111, its kinetic energy is reduced through energy conversion, and it will fall into the dust collection trough 323 under the action of gravity, thereby automatically collecting the debris.

[0054] The working principle of this invention is as follows: The dust collection channel 322 and the dust suction chamber 321 are connected and arranged along the direction of the flying debris from the grinding head 23, improving the debris collection efficiency. Simultaneously, the airflow cools the area being ground on the battery casing, ensuring grinding quality. During grinding, the grinding debris is carried by the airflow into the dust collection channel 322 and impacts the transmission plate 411, causing it to rotate. During rotation, the transmission plate 411 drives the magnetic rod 412 to insert into the coil 413. The magnetic rod is made of magnetic material, and the coil 413 cuts magnetic lines of field, generating an induced current. When the thickness of the area to be ground on the battery casing increases... As the number of debris particles entering the dust collection channel 322 increases, the entrainment of gas also increases, causing the rotation angle of the transmission plate 411 to increase, resulting in a greater induced current. The transmission plate 411 is a split design. When the rotating plate 4111 rotates, it drives the sliding plate 4112 to move up along the slope of the detection chamber 324. The sliding plate 4112 slides upward in the groove of the rotating plate 4111. As the grinding progresses, the surface of the battery casing gradually reaches the standard, the amount of debris entering the dust collection channel 322 decreases, and the sliding plate 4112 slides down the slope under the action of gravity, driving the rotating plate 4111 to rotate and automatically reset, thereby enabling real-time detection of the grinding quality of the battery casing surface. The dust collection channel 322 is located on the side closest to the battery casing, while the detection chamber 324 is located on the outside of the dust collection channel 322. When the thickness of the battery casing to be polished increases, the instantaneous heat generated increases. By adjusting the current input to the current-raising electromagnet 422, the current-raising plate 421 moves upward along the adjustment groove 325 under the action of repulsion, expanding the cross-sectional area of ​​the flow channel and thereby increasing the airflow velocity near the polishing head 23. The heat dissipation effect is automatically adjusted according to the different thicknesses of the battery casing, thereby ensuring polishing efficiency.
