Technical Field
[0001] This invention relates to the field of intelligent manufacturing and industrial automation technology, and more specifically, to a novel battery cover assembly method. Background Technology
[0002] In the production and manufacturing of battery covers, the bare plate is the basic metal substrate of the battery cover. It is a semi-finished substrate that has not yet been assembled with core components such as explosion-proof valves, sealing rings, and terminals. It is the starting point and core carrier of the entire battery cover assembly process. The bare plate is usually made of high-strength, corrosion-resistant metal materials, with aluminum alloy or stainless steel being the mainstream materials. The specific choice needs to match the battery's safety requirements and lightweight requirements.
[0003] The inherent quality of the blank sheet directly determines the stability of subsequent processes. In the traditional process, the pre-treated metal substrate is first fed into the feeding station of the stamping machine and fixed on the reference surface of the lower die by the positioning mechanism. When the upper and lower dies of the stamping machine are closed, the die shape cutting module separates the sheet material from the waste material by the shearing force of the cutting edge, forming the outer frame of the blank sheet. At the same time, the punch of the hole punching module punches out the injection hole, explosion-proof valve hole and pole hole, forming the blank sheet in one stamping process. However, traditional stamping equipment molds are prone to wear after long-term use, leading to burrs on the walls of the blank plate holes. This has multiple adverse effects on subsequent processes. For example, burrs on the inner walls of the blank plate terminal hole hinder the precise fit between the terminal and the hole wall, causing weak riveting and localized overheating during charging and discharging. Burrs on the inner walls of elliptical explosion-proof holes damage the welding seal and the normal pressure relief function of the explosion-proof valve, adversely affecting subsequent processes and battery safety. Therefore, it is necessary to grind the walls of the blank plate holes to remove burrs. Traditional grinding methods have significant limitations for different hole shapes in the blank plate. Elliptical explosion-proof holes require multi-axis linkage equipment to adapt to the hole shape, which is costly and complex to operate. Manually adjusting the grinding path is inefficient and inconsistent. Grinding of circular terminal holes is mostly done one hole at a time, resulting in low processing efficiency. Furthermore, the blank plate positioning stability is insufficient during grinding, and the metal debris generated during grinding is prone to accumulation and contamination, further affecting grinding accuracy and the production environment. In view of this, we propose a new battery cover assembly method. Summary of the Invention

A plurality of balls are movably arranged on the top of the sliding ring plate, and a plurality of balls with the same structure as the top are arranged on the bottom of the sliding ring plate.

[0012] Preferably, the top of the control frame is also rotatably arranged with multiple gears four, which mesh with gears three.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention designs a grinding assembly that relies on the synchronous drive of gear three to rotate gear four, enabling the round hole grinding machine and the elliptical hole grinding machine to be driven by the same motor two, without the need for an additional power source. The control frame in the grinding assembly can drive the elliptical hole grinding machine and multiple round hole grinding machines to move synchronously. Moreover, the two types of grinding machines can move along elliptical and circular paths respectively, which can specifically grind the inner walls of the elliptical explosion-proof holes and circular positive and negative terminal hole holes of the bare plate body, achieving precise matching grinding of different hole shapes, thoroughly cleaning the hole wall burrs, and avoiding the adverse effects of burrs on the subsequent battery cover assembly process. This solves the problem that traditional grinding equipment is difficult to grind simultaneously for different hole shapes of bare plates.
[0015] 2. This invention designs an arc-shaped protrusion plate one on the side wall of the support column and an arc-shaped protrusion plate two on the side wall of the support frame. The two are arranged at opposite angles in the grinding station of the base frame. When the material rack enters the grinding station with the rotating frame, the arc-shaped protrusion plate one makes contact with the arc block of one of the clamping components, pushing the pressure plate to move into the positioning groove and insert into the top of the polished plate body. Combined with the positioning groove, it forms a stable clamping of the polished plate body. The arc-shaped protrusion plate two cooperates with the arc block of another clamping component in the same principle to enhance the clamping effect on the polished plate body and ensure that the polished plate body will not shift during subsequent grinding operations. When the material rack leaves the grinding station with the rotating frame, it automatically resets, which is convenient for unloading. The whole process does not require additional power to drive the clamping action. The natural displacement of the material rack entering the grinding station triggers the compression cooperation between the arc-shaped protrusion plate and the arc block, which simplifies the structure and reduces energy consumption.
[0016] 3. This invention also designs an elliptical groove and an elliptical block. When the rotating cylinder rotates on the outer wall of the fixed column, the drive plate rotates circumferentially with it. The drive groove generates a circumferential thrust on the drive column, while the annular guide channel restricts the drive column to slide only along an elliptical path. The two work together to drive the elliptical hole grinder as a whole to move along an elliptical path. Ultimately, the grinding head of the elliptical hole grinder precisely fits the inner wall of the elliptical explosion-proof hole of the main body of the polished plate, achieving comprehensive and uniform grinding of the inner wall of the explosion-proof hole and thoroughly cleaning the burrs on the hole wall. It can achieve precise matching between the grinding head and the inner wall of the elliptical explosion-proof hole without the need for a complex multi-axis drive system or programming control. This solves the technical problems of traditional grinding methods, which require multi-axis linkage equipment to match the hole shape for elliptical explosion-proof holes, resulting in high equipment costs and complex operation, as well as low efficiency and poor consistency of manual adjustment of the grinding path.
[0017] 4. This invention also designs inner and outer guide blocks. During the movement of the elliptical hole grinder along the elliptical path, the inner guide block at the bottom of the elliptical block and the outer guide block at the bottom of the control frame form a double-layer guide structure. The elliptical sliding groove one on the outer side wall of the inner guide block and the elliptical sliding groove two on the inner side wall of the outer guide block together limit the sliding ring plate on the outer circumference of the drive column, ensuring that the sliding ring plate always slides within the gap between the inner and outer guide blocks. At the same time, multiple balls at the top and bottom of the sliding ring plate form a rolling fit with the inner walls of sliding groove one and sliding groove two, respectively. When the drive column moves along the elliptical path under the thrust of the drive groove and the limiting action of the annular guide channel, the sliding ring plate moves synchronously with the drive column. The ball converts the sliding friction between the sliding ring plate and the guide block into rolling friction, which greatly reduces the motion resistance. Moreover, the cooperation between the double-layer guide groove and the sliding ring plate can effectively counteract the radial shaking generated during the grinding of the elliptical hole grinder, ensuring that the drive column always moves smoothly along the preset elliptical path. This ensures the fitting accuracy between the grinding head of the elliptical hole grinder and the inner wall of the elliptical explosion-proof hole of the main body of the polished plate, and avoids the problem of uneven grinding of the hole wall caused by the offset of the grinding head.
[0018] 5. During the polishing of the main body of the plate, as the control frame moves down with the lifting platform, the inserts on the side wall of the control frame will be inserted into the corresponding holes on the top of the material rack. The frustum-shaped opening structure at the entrance of the hole guides the inserts to be inserted accurately. When the insert is fully inserted into the hole, the sealing gasket at the bottom of the outer circumferential cover plate will tightly fit the edge of the hole entrance, forming a seal and preventing air leakage during dust collection. At this time, the inclined plates symmetrically arranged in opposite directions in the inner cavity of the material rack can guide the metal debris generated by polishing to concentrate in the inner cavity of the material rack, making it convenient for the dust collection holes to suck it up. After the external dust collection equipment is started, it will form a negative pressure dust collection channel through the suction pipe, flexible pipe, inserts, holes and dust collection holes, quickly sucking in and expelling the metal debris accumulated in the material rack. This design can clean up the debris generated by polishing in real time and avoid debris contaminating the equipment or endangering the operators.
[0019] 6. This invention also designs a plug-in structure for the plug and the socket. When the main body of the polished plate is being polished, as the control frame moves down with the lifting platform, the plugs on the side wall of the control frame will plug into the corresponding sockets on the top of the material rack, automatically establishing a rigid alignment relationship between the control frame and the material rack. This achieves precise calibration of their relative positions, providing a positional reference for precise polishing. At the same time, it fixes the four corners of the control frame, preventing the control frame from shaking violently due to equipment vibration or polishing impact when the control frame drives the elliptical hole polisher or the round hole polisher for polishing operations. This ensures that the polishing head always keeps stable contact with the hole wall for polishing, effectively avoiding problems such as uneven polishing of the hole wall and dimensional deviations caused by vibration.

[0023] Example 2, as Figures 1 to 15 As shown, this embodiment provides a grinding device, which includes a device frame 1. A monitoring mechanism 2, a feeding assembly 3, a grinding assembly 4, and a feeding robotic arm 5 are arranged on the top of the device frame 1. The feeding assembly 3 includes a base frame 31, a rotating frame 32 rotatably arranged on the top of the base frame 31, and multiple material racks 33 arranged on the top of the rotating frame 32. Each material rack 33 has a positioning groove 3301 on its top, used for positioning the polished plate body 6. A clamping assembly 34 is arranged on the side wall of the material rack 33. When the material rack 33 rotates to the grinding area of the grinding assembly 4, the clamping assembly 34 automatically clamps the polished plate body 6 in the positioning groove 3301. The monitoring mechanism 2 is arranged above the monitoring station of the base frame 31. The monitoring mechanism 2 is a conventional device that monitors using sensors. When the material rack 33 enters the monitoring station, the monitoring mechanism 2 can monitor the position accuracy of the polished plate body 6 in the positioning groove 3301, and can pre-screen for positioning anomalies. The main body 6 of the polished plate reduces subsequent ineffective polishing operations and lowers material loss. The polishing assembly 4 is arranged above the polishing station of the base frame 31, and the unloading robotic arm 5 is arranged to the side of the unloading station of the base frame 31, enabling automatic unloading. The polishing assembly 4 includes a control frame 41, under which are arranged an elliptical hole polishing machine 42 and multiple round hole polishing machines 43. The control frame 41 can drive the elliptical hole polishing machine 42 and the round hole polishing machines 43 to move up and down. Hole grinder 42 and round hole grinder 43 can move along different paths simultaneously; when the feed rack 33 of the feeding assembly 3 transports the smooth plate body 6 into the grinding area, the grinding head of the elliptical hole grinder 42 can move along an elliptical path to perform specialized grinding on the inner wall of the explosion-proof hole of the smooth plate body 6, and the grinding heads of multiple round hole grinders 43 can move along a circular path simultaneously to perform specialized grinding on the inner wall of the positive and negative electrode holes of the smooth plate body 6.
[0024] This invention designs a grinding component 4 in which a control frame 41 can drive an elliptical hole grinding machine 42 and multiple circular hole grinding machines 43 to move synchronously. The two types of grinding machines can move along elliptical and circular paths respectively, which can specifically grind the inner walls of the elliptical explosion-proof holes and circular positive and negative terminal holes of the bare plate body 6. This achieves precise matching grinding of different hole shapes, thoroughly cleans the burrs on the hole walls, avoids the burrs from adversely affecting the subsequent battery cover assembly process, and thus improves the sealing performance, structural robustness and safety of the finished battery cover.
[0025] In another embodiment of the present invention, a support column 35 and a support frame 36 are connected to the top of the base frame 31. An annular wheel rail 3101 is also arranged on the top of the base frame 31. Multiple rollers are connected to the bottom of the rotating frame 32. The rotating frame 32 is rotatably arranged on the outer circumference of the support column 35, and the multiple rollers at the bottom form a rolling engagement with the annular wheel rail 3101. A motor 37 is arranged on the inner side wall of the equipment frame 1. A gear 38 is connected to the output end of the motor 37. The gear 38 is rotatably arranged on the top of the base frame 31. A toothed edge is arranged on the outer circumference of the rotating frame 32. The toothed edge meshes with the gear 38. The motor 37 drives the gear 38 to rotate, which in turn drives the rotating frame 32 to rotate around the support column 35. At the same time, multiple rollers at the bottom of the rotating frame 32 and the annular wheel rail 3101 at the top of the base frame 31 form a rolling engagement, which not only guides the rotation of the rotating frame 32, but also reduces the friction during the rotation process. This allows the rotating frame 32 to smoothly and steadily drive the multiple material racks 33 at the top to the monitoring station, the grinding station and the unloading station in sequence, realizing the continuous conveying of the bare plate body 6.
[0026] In another embodiment of the present invention, the side wall of the support column 35 is connected to an arc-shaped protrusion 3501, and the side wall of the support frame 36 is connected to an arc-shaped protrusion 3601. The arc-shaped protrusion 3501 and the arc-shaped protrusion 3601 are arranged at opposite angles in the grinding station of the base frame 31. There are two clamping components 34 on the material rack 33, and the two clamping components 34 are arranged symmetrically. One of the clamping components 34 includes a pressure plate 3401 that moves through the side wall of the material rack 33. The side wall of the pressure plate 3401 is integrally formed with a fixing plate 3402, and the side wall of the fixing plate 3402 is connected to an arc block 3403. The side wall of the material rack 33 is provided with multiple slots, and the inner side wall of the slots is connected to a guide rod 3302. A spring 3303 is fitted on the outer circumference of the 302 guide rod 3302, and a limiting plate 3304 is connected to the end of the guide rod 3302. The guide rod 3302 moves through the side wall of the fixed plate 3402, and the limiting plate 3304 is arranged on the side of the fixed plate 3402. The spring 3303 is arranged on the other side of the fixed plate 3402 between the spring and the slot. When the material rack 33 enters the grinding station, the arc-shaped protrusion 3501 can form a pressing contact with the arc block 3403 of one of the clamping components 34, and push the pressure plate 3401 to insert into the top of the smooth plate body 6 in the positioning groove 3301, and form a clamping state for the smooth plate body 6 with the positioning groove 3301. The arc-shaped protrusion 3601 is the same as the arc-shaped protrusion 3501.
[0027] This invention features an arc-shaped protrusion 3501 on the side wall of the support column 35 and an arc-shaped protrusion 3601 on the side wall of the support frame 36. These two protrusions are arranged at opposing angles within the grinding station of the base frame 31. When the material rack 33 enters the grinding station along with the rotating frame 32, the arc-shaped protrusion 3501 presses against the arc block 3403 of one of the clamping components 34, pushing the pressure plate 3401 into the positioning groove 3301 and inserting it into the top of the polished plate body 6. This, combined with the positioning groove 3301, creates a stable surface for the polished plate body 6. Clamping; the arc-shaped convex plate 3601 will cooperate with the arc block 3403 of another clamping component 34 in the same principle to enhance the clamping effect on the smooth plate body 6, ensuring that the smooth plate body 6 will not shift during subsequent grinding operations. When the material rack 33 leaves the grinding station with the rotating frame 32, it will automatically reset, which is convenient for unloading. The whole process does not require additional power to drive the clamping action. The natural displacement of the material rack 33 entering the grinding station triggers the squeezing cooperation between the arc-shaped convex plate and the arc block 3403, which simplifies the structure and reduces energy consumption.
[0028] In an embodiment of the present invention, the grinding assembly 4 further includes a frame 44 arranged on the top of the support column 35 and the support frame 36. A cylinder 45 is arranged on the top of the frame 44, and a lifting platform 46 is slidably arranged in the inner cavity of the frame 44. The output end of the cylinder 45 is connected to the top of the lifting platform 46, and a control frame 41 is connected to the bottom of the lifting platform 46. When grinding is required, the output end of cylinder 45 extends and retracts, driving the connected lifting platform 46 to slide vertically within the inner cavity of frame 44. The lifting of the lifting platform 46 simultaneously drives the control frame 41 and the oval hole grinding machine 42 and round hole grinding machine 43 below the control frame 41 to rise and fall together, thereby precisely adjusting the distance between the grinding machine and the polished plate body 6 on the material rack 33. During grinding, cylinder 45 pushes the lifting platform 46 downward, causing the grinding heads of the oval hole grinding machine 42 and round hole grinding machine 43 to descend to the wall of the hole to be ground that is in contact with the polished plate body 6. After grinding is completed, cylinder 45 pulls the lifting platform 46 upward, causing the grinding machine to detach from the polished plate body 6, facilitating the material rack 33 to flow to the next work station, thus achieving an orderly connection between grinding operations and work station flow.
[0029] In another embodiment of the present invention, a second motor 4101 is installed on the side wall of the control frame 41. The output end of the second motor 4101 is connected to a driving pulley 4102. The driving pulley 4102 is connected to a driven pulley 4103 via a transmission belt. The driven pulley 4103 is rotatably arranged on the top of the control frame 41, and a second gear 4104 is coaxially connected to the driven pulley 4103. An elliptical groove 4105 is formed from top to bottom on the control frame 41. An elliptical block 4106 is arranged in the inner cavity of the elliptical groove 4105. The top of the elliptical block 4106 is connected to the control frame 41 via a fixed column 4107. An annular guide channel is formed between the elliptical groove 4105 and the elliptical block 4106. The annular guide channel has an elliptical path structure. The circumference of the fixed column 4107 is... A rotating cylinder 4108 is rotatably arranged on the outer wall. A gear 3 4109 and a drive plate 4110 are connected to the outer circumference of the rotating cylinder 4108. The gear 3 4109 meshes with the gear 2 4104. The drive plate 4110 has a drive groove 4111 from top to bottom. The top of the elliptical hole grinder 42 is connected to a drive column 4201. The drive column 4201 is movably arranged in the annular guide channel and the drive groove 4111. When the rotating cylinder 4108 rotates, it can drive the drive column 4201 to slide in the annular guide channel through the drive groove 4111 of the drive plate 4110, so that the elliptical hole grinder 42 performs elliptical path movement. That is, the grinding head of the elliptical hole grinder 42 forms a state of grinding the inner wall of the elliptical explosion-proof hole of the smooth plate body 6.
[0030] This invention, through the design of elliptical groove 4105 and elliptical block 4106, allows the motor 4101 on the side wall of control frame 41 to rotate when it is started. Its output drives the drive pulley 4102 to rotate, which in turn drives the driven pulley 4103 to rotate synchronously via a transmission belt. The gear 4104, coaxially connected to the driven pulley 4103, rotates accordingly. Because gear 4104 meshes with gear 4109 on the outer wall of rotating drum 4108, rotating drum 4108 rotates synchronously on the outer circumference of fixed column 4107. Drive plate 4110 rotates circumferentially with it, and drive groove 4111 generates circumferential thrust on drive column 4201. Meanwhile, the annular guide channel restricts the drive... The moving column 4201 can only slide along an elliptical path. The two work together to drive the elliptical hole grinder 42 to move along an elliptical path. Ultimately, the grinding head of the elliptical hole grinder 42 precisely fits the inner wall of the elliptical explosion-proof hole of the main body 6 of the smooth plate, achieving comprehensive and uniform grinding of the inner wall of the explosion-proof hole and thoroughly cleaning the burrs on the hole wall. It can achieve precise matching between the grinding head and the inner wall of the elliptical explosion-proof hole without the need for a complex multi-axis drive system or programming control. It solves the technical problems of traditional grinding methods, which require multi-axis linkage equipment to match the hole shape for elliptical explosion-proof holes, resulting in high equipment costs and complex operation, as well as low efficiency and poor consistency of manual adjustment of the grinding path.
[0031] In another embodiment of the present invention, an inner guide block 47 is detachably connected to the bottom of the elliptical block 4106 by bolts, and an outer guide block 48 is detachably connected to the bottom of the control frame 41 by bolts. A sliding groove 1 is arranged on the outer side wall of the inner guide block 47, and the sliding groove 1 has an elliptical path structure. A sliding groove 2 is arranged on the inner side wall of the outer guide block 48, and the sliding groove 2 has an elliptical path structure. A sliding ring plate 4202 is rotatably arranged on the outer circumference of the drive column 4201. The sliding ring plate 4202 is arranged between the outer guide block 48 and the inner guide block 47, and the side wall of the sliding ring plate 4202 slides in cooperation with the sliding groove 1 and the sliding groove 2 respectively. A plurality of balls 4203 are movably arranged on the top of the sliding ring plate 4202, and a plurality of balls 4203 with the same structure as the top are arranged on the bottom of the sliding ring plate 4202. The balls 4203 roll in cooperation with the inner walls of the sliding groove 1 and the sliding groove 2 respectively.
[0032] This invention, through the design of an inner guide block 47 and an outer guide block 48, creates a double-layer guide structure during the movement of the elliptical hole grinder 42 along an elliptical path. The inner guide block 47 at the bottom of the elliptical block 4106 and the outer guide block 48 at the bottom of the control frame 41 form a double-layer guide structure. The elliptical sliding groove one on the outer wall of the inner guide block 47 and the elliptical sliding groove two on the inner wall of the outer guide block 48 together limit the sliding ring plate 4202 on the outer circumference of the drive column 4201, ensuring that the sliding ring plate 4202 always slides within the gap between the inner guide block 47 and the outer guide block 48. Simultaneously, multiple balls 4203 at the top and bottom of the sliding ring plate 4202 roll against the inner walls of the sliding groove one and sliding groove two, respectively. In conjunction with the driving column 4201, when it moves along the elliptical path under the thrust of the driving groove 4111 and the limiting action of the annular guide channel, the sliding ring plate 4202 moves synchronously with the driving column 4201. The ball bearing 4203 converts the sliding friction between the sliding ring plate 4202 and the guide block into rolling friction, greatly reducing the motion resistance. Moreover, the cooperation between the double-layer guide groove and the sliding ring plate 4202 can effectively counteract the radial shaking generated during the grinding of the elliptical hole grinder 42, ensuring that the driving column 4201 always moves smoothly along the preset elliptical path. This ensures the fitting accuracy between the grinding head of the elliptical hole grinder 42 and the inner wall of the elliptical explosion-proof hole of the main body 6, avoiding uneven grinding of the hole wall caused by the offset of the grinding head.
[0033] In another embodiment of the present invention, a plurality of gears 4112 are rotatably arranged on the top of the control frame 41. The gears 4112 mesh with gears 4109. The control frame 41 is also provided with a plurality of circular grooves 4113 from top to bottom. An annular sliding groove 4114 is provided on the inner sidewall of the circular groove 4113. A circular rotating plate 4115 is slidably arranged in the annular sliding groove 4114. A rotating column 4116 is connected to the top of the circular rotating plate 4115. The rotating column 4116 is rotatably arranged. A gear 4117 is connected to the outer circumference of the control frame 41 and the rotating column 4116. The gear 4117 meshes with the gear 4112. The circular hole grinder 43 is installed at the bottom eccentric position of the circular rotating plate 4115, so that when the circular rotating plate 4115 rotates, it can drive the circular hole grinder 43 to perform circular motion. The grinding head of the circular hole grinder 43 forms a state of grinding the inner side wall of the circular positive or negative terminal hole of the main body of the polished plate 6.
[0034] Multiple gears 4112 on the top of the control frame 41 mesh with gears 4109 on the outer wall of the rotating drum 4108. When gears 4109 rotate with the rotating drum 4108, they synchronously drive gears 4112 to rotate. Gears 4117 meshing with gears 4112 rotate accordingly, thereby driving the rotating column 4116 to rotate as well, causing the circular rotating plate 4115 to rotate within the circular groove 4113 of the control frame 41. The circular rotating plate 4115 also achieves sliding limit through the annular sliding groove 4114 to ensure stable rotation without deviation. Due to the offset of the circular hole grinding machine 43 installed at the bottom of the circular rotating plate 4115... At the center position, when the circular rotating plate 4115 rotates, the circular hole grinder 43 will move in a circular motion with the rotating plate. The movement trajectory of its grinding head is perfectly matched with the inner wall of the positive and negative terminal holes of the main body 6 of the polished plate, so as to accurately fit the hole wall for grinding operations and achieve comprehensive cleaning of burrs on the inner wall of the positive and negative terminal holes. At the same time, this design relies on gear three 4109 to synchronously drive gear four 4112, so that the circular hole grinder 43 and the elliptical hole grinder 42 can be driven by the same motor two 4101, without the need for an additional power source, simplifying the equipment structure, ensuring synchronous operation of the two types of grinders, and improving the overall processing efficiency of the polished plate.
[0035] In an embodiment of the present invention, the top of the material rack 33 is provided with four insertion holes 3305, which are arranged in a four-corner orientation. The entrance of each insertion hole 3305 has a frustum-shaped opening. Multiple inclined plates 3306 are arranged inside the material rack 33, with two inclined plates 3306 arranged symmetrically and facing each other. Multiple dust suction holes 3307 are provided on the inner sidewall of the material rack 33, and the inner cavities of the insertion holes 3305 and the multiple dust suction holes 3307 are in communication. Multiple insertion posts 49 are connected to the sidewall of the control frame 41. The insertion posts 49 are connected to... The insertion hole 3305 can form a plug-in fit. The outer circumference of the insertion post 49 is provided with a cover plate 4901. The bottom of the cover plate 4901 is provided with a sealing gasket 4902. When the insertion post 49 is inserted into the inner cavity of the insertion hole 3305, the sealing gasket 4902 can form a sealing state at the entrance of the insertion hole 3305. The top of the insertion post 49 is connected to the suction pipe 410 through a flexible tube. The flexible tube connection method can be adapted to the lifting action of the control frame 41. The suction pipe 410 is arranged on the top of the frame 44, and one end of the suction pipe 410 is connected to the external vacuuming equipment.
[0036] This invention also designs a sealing structure for the insertion of the insert 49 and the insertion hole 3305, and a debris guiding structure for the inclined plate 3306. During the grinding operation of the main body 6, as the control frame 41 moves down with the lifting platform 46, the insert 49 on the side wall of the control frame 41 will correspondingly insert into the insertion hole 3305 on the top of the material rack 33. The frustum-shaped opening structure at the entrance of the insertion hole 3305 guides the insert 49 to be precisely inserted. After the insert 49 is fully inserted into the insertion hole 3305, the sealing gasket 4902 at the bottom of its circumferential outer wall cover plate 4901 will tightly fit against the edge of the entrance of the insertion hole 3305, forming a sealing structure. The system is sealed to prevent air leakage during dust collection. At this time, the inclined plates 3306, which are symmetrically and inclined in opposite directions inside the material rack 33, can guide the metal debris generated by grinding to concentrate in the inner cavity of the material rack 33, making it convenient for the dust collection hole 3307 to suck it up. After the external dust collection equipment is started, it will form a negative pressure dust collection channel through the suction pipe 410, flexible pipe, insertion post 49, insertion hole 3305 and dust collection hole 3307, which will quickly suck up and discharge the metal debris accumulated in the material rack 33. This design can clean up the debris generated by grinding in real time, and avoid debris contaminating the equipment or endangering the operators.
[0037] This invention also designs a plug-in structure between the insert post 49 and the insertion hole 3305. When the polishing operation of the main body 6 is carried out, as the control frame 41 moves down with the lifting platform 46, the insert post 49 on the side wall of the control frame 41 will be plugged into the insertion hole 3305 on the top of the material rack 33. This automatically establishes a rigid alignment relationship between the control frame 41 and the material rack 33, achieving precise calibration of their relative positions and providing a positional reference for precise polishing. At the same time, it forms a four-corner fixation of the control frame 41, preventing the control frame 41 from shaking violently due to equipment vibration or polishing impact when the control frame 41 drives the elliptical hole polishing machine 42 and the round hole polishing machine 43 to perform polishing operations. This ensures that the polishing head always keeps stable contact with the hole wall for polishing, effectively avoiding problems such as uneven polishing of the hole wall and dimensional deviation caused by vibration.
[0038] Example 3: This example provides a method for using a grinding device, including the following steps: S1. Plate loading and monitoring operation: The stamped plate body 6 is placed into the top positioning groove 3301 of the material rack 33. The motor 37 is started. The motor 37 is driven by the gear 38 meshing with the tooth of the rotating frame 32, which drives the rotating frame 32 to rotate smoothly around the support column 35 along the annular wheel track 3101. The material rack 33 carrying the plate body 6 is moved to the monitoring station. The motor 37 stops and the monitoring mechanism 2 starts to detect the position of the plate body 6 in the positioning groove 3301. If the plate body 6 is not deviated or tilted, the motor 37 continues to run and the material rack 33 is moved to the grinding station. If the detection is not qualified, the equipment issues an alarm signal. The unqualified plate is removed by manual or auxiliary robot and reloaded or judged as scrap. S2. During the plate clamping and fixing operation, after the material rack 33 enters the grinding station, the motor 37 stops and the rotating frame 32 is locked in position. At this time, the arc-shaped protrusion 3501 of the support column 35 presses against the arc block 3403 of the clamping component 34 on one side of the material rack 33, pushing the pressure plate 3401 to move along the guide rod 3302 into the positioning groove 3301 and inserting it into the top of the plate body 6. At the same time, the arc-shaped protrusion 3601 of the support frame 36 presses against the arc block 3403 of the clamping component 34 on the other side, similarly pushing the corresponding pressure plate 3401 to press the plate body 6, forming a stable clamping with the positioning groove 3301, and the spring 3303 is compressed and stores energy. S3. Grinding components are aligned and debris is prepared. Cylinder 45 is started. The output end of cylinder 45 pushes the lifting platform 46 down along the inner cavity of the frame 44, driving the control frame 41 and the elliptical hole grinder 42 and round hole grinder 43 below to descend synchronously. During the descent, the insertion post 49 on the side wall of the control frame 41 is aligned with the insertion hole 3305 on the top of the material rack 33. Under the guidance of the frustum-shaped opening of the insertion hole 3305, it is accurately inserted. The sealing gasket 4902 at the bottom of the cover plate 4901 is tightly attached to the edge of the entrance of the insertion hole 3305 to form a seal. The external dust collection equipment is started, and a negative pressure dust collection channel is constructed through the suction pipe 410, flexible pipe, insertion post 49, insertion hole 3305 and dust collection hole 3307. S4. Hole wall burr grinding and metal shavings removal operation: When the grinding heads of the elliptical hole grinder 42 and the round hole grinder 43 descend to the position corresponding to the hole wall of the smooth plate body 6, the cylinder 45 stops moving, keeping the lifting platform 46 in a fixed position; the second motor 4101 is started, and the second motor 4101 drives the driving pulley 4102 to rotate, which drives the driven pulley 4103 and the coaxial gear 4104 to rotate through the transmission belt; the second gear 4104 meshes with the third gear 4109 of the rotating drum 4108, driving the rotating drum 4108 to rotate around the fixed column 4107, and the drive plate 4110 pushes the drive column 4201 along the annular guide channel to make an elliptical movement through the drive groove 4111. The circular path movement allows the grinding head of the elliptical hole grinder 42 to simultaneously perform specialized grinding on the inner wall of the elliptical explosion-proof hole; simultaneously, gear three 4109 drives the meshing gear four 4112 to rotate, and gear four 4112 drives gear five 4117 and rotating column 4116 to rotate, causing the circular rotating plate 4115 to rotate along the annular slide groove 4114. The eccentrically mounted circular hole grinder 43 moves in a circular motion with the circular rotating plate 4115, and the grinding heads of multiple circular hole grinders 43 simultaneously perform specialized grinding on the inner wall of the positive and negative pole hole; the metal chips generated by grinding are guided by the inclined plate 3306 to concentrate in the inner cavity of the material rack 33, and are quickly sucked in and discharged from the equipment by the negative pressure dust suction channel; S5. Grinding completion and component reset operation: After the grinding operation is completed, turn off motor 4101, and stop the movement of elliptical hole grinder 42 and round hole grinder 43; turn off the external dust collection equipment to stop debris adsorption; start cylinder 45 to drive the lifting platform 46, control frame 41 and grinder to move upward, insert post 49 is pulled out from insert hole 3305, and the sealing state is released; at the same time, material rack 33 starts to rotate with rotating frame 32, the arc block 3403 of clamping component 34 is released from the pressure of arc convex plate 1 3501 and arc convex plate 2 3601, spring 3303 resets and pushes fixed plate 3402 and pressure plate 3401 back to their original position, releasing the smooth plate body 6; S6. Unloading and transfer of the polished plate: Motor 37 continues to drive the rotating frame 32 to rotate, and the polished plate body 6 is transferred to the unloading station. The unloading robot arm 5 starts, grabs the polished plate body 6 in the positioning slot 3301, and transfers it to the assembly line carrier of the next process to complete a single polishing cycle. The steps are repeated in this way to realize the continuous automated polishing process of the polished plate body 6.
