[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figure 1 As shown, the present invention provides a specific embodiment of a rotary battery tray bottom plate aluminum sheet grinding equipment, including a grinding platform 1, a grinding device 2, a driving mechanism 3, and a pressing mechanism.

[0042] The grinding platform 1 has a groove 11 on its top for placing a battery tray, and also has control buttons to control the relevant devices through the electrical control cabinet 15.

[0043] In this embodiment, the workpiece to be polished is a battery tray, the projected surface of the battery tray is rectangular, and the groove 12 is also rectangular.

[0044] The grinding device 2 is used to grind the polyurethane and electrophoretic layers at the insulation monitoring points of the battery tray bottom plate; the grinding device 2 is provided in multiple sets, with one set of grinding device 2 corresponding to each insulation monitoring point.

[0045] The drive mechanism 3 includes a telescopic device that drives the grinding device 2 to move in the vertical direction, and a first moving device that drives the telescopic device to move. The first moving device is disposed on the grinding platform 1. The first moving device is used to move the grinding device 2 between the inside of the groove 1 and the outside of the groove 11, so that the grinding device 2 can be located directly above the grinding position of the workpiece.

[0046] The first moving device drives the rotation of the telescopic device, so that the grinding device 2 can be positioned directly above the insulation monitoring point; the telescopic device drives the grinding device 2 to move downward to grind the polyurethane and electrophoretic layer at the insulation monitoring point.

[0047] When loading materials, rotate the device to the outside of the processing area for easy loading. When grinding, rotate the device to the top of the processing area to prepare for grinding operations.

[0048] The pressing mechanism includes a pressing plate 51 and a second moving device for driving the pressing plate 51 to move; the second moving device 52 is used to move the pressing plate 51 between the inside of the groove 11 and the outside of the grinding platform 1.

[0049] Under the action of the second moving device, the lower pressure plate 51 can apply pressure to the position of the non-insulated monitoring point on the bottom plate of the battery tray in the groove 11 to achieve the clamping and fixing of the battery tray.

[0050] The lower pressure plate 51 is provided with multiple sets of suction cup devices 511 on the surface that contacts the battery tray. The suction cup devices 511 can adsorb the battery tray. Under the action of the second moving device, the lower pressure plate 51 can be moved to the outside of the grinding platform 1, and the side of the lower pressure plate 51 with the suction cup devices 511 is facing down, so that the battery tray can be moved to the outside of the grinding platform to realize unloading.

[0051] In this embodiment, in order to facilitate material loading, a ball bearing 13 is provided on the surface of the grinding platform 1 between the groove 11 and the external feeding device. The external feeding device is at the same height as the grinding platform 1. The operator slides the battery tray along the ball bearing 11 into the groove 11.

[0052] In this embodiment, to facilitate material unloading, the external feeding device is positioned directly below the flipped lower pressure plate. After the lower pressure plate flips, the suction cup stops adsorbing the battery tray, and the battery tray falls onto the feeding device. To prevent the battery tray from falling and causing damage, the battery tray can come into contact with the conveyor belt after the lower pressure plate flips to its lowest position.

[0053] The following provides an embodiment of the pressing mechanism, such as... Figure 9 and Figure 10 As shown:

[0054] The pressing mechanism also includes a frame 517; the pressing plate 51 has symmetrical first rotating shafts 519 on both sides, the pressing plate 51 is set inside the frame 517 and is rotatably connected to the frame 517; the second moving device 52 drives the frame 517 to rotate relative to the grinding platform 1, and the rotating shaft of the frame 517 is parallel to the grinding platform 1; so that the pressing plate 51 remains horizontal during the rotation of the frame 517, and avoids the battery tray adsorbed by the pressing plate 51 from rotating with the frame 517 during the unloading process, thus avoiding safety hazards.

[0055] The frame 517 extends outward at both ends of its side located in the direction of its own rotation axis to form a connector 525. The end of the connector 525 is provided with a second rotating shaft 523. The grinding platform 1 is provided with a bearing seat 524. The second rotating shaft 523 and the bearing seat 524 are interference-fitted.

[0056] The second moving device 52 includes a drive motor 521 and a gear set 522. The drive motor 521 is mounted on the grinding platform 1, and the drive motor 521 drives the second rotating shaft 523 of the frame 517 to rotate through the gear set 522.

[0057] After the suction cup device 511 adsorbs the battery tray, the second moving device 52 is activated, causing the frame 11 to flip to the outside of the grinding platform 1. During this process, the lower pressure plate remains in a horizontal state, so that after the frame flips, the side of the lower pressure plate that adsorbs the battery tray always faces downwards, which can transfer the battery tray to the feeding device for unloading.

[0058] Furthermore, in this embodiment, during the process of the lower pressure plate 51 applying pressure to the workpiece inside the groove 11, the bottom of the frame 517 contacts the grinding platform 1; the grinding platform 1 is provided with an electromagnet module 14 at the position in contact with the frame 517, and the frame 517 is made of a material that can be magnetically attracted; the electromagnet module 14 can be magnetically attracted to the frame 517.

[0059] Furthermore, in this embodiment, the bottom of the lower pressure plate 51 is vertically downwardly provided with a first cylinder 515 and a second cylinder 518, and the suction cup device 511 is disposed at the end of the piston rod of the second cylinder 518.

[0060] The piston rod end of the first cylinder 515 is used to apply pressure to the battery tray located inside the groove 11. The piston rod end of the first cylinder 515 is provided with a rubber pad 516 to avoid indenting the battery tray.

[0061] When the pressure plate 51 applies pressure to the bottom plate of the battery tray, the insulation monitoring point is located between the first pressure plate 512 and the second pressure plate 513, and after the first cylinder 515 extends, the rubber pad 516 can act on the bottom plate of the battery tray to clamp and fix the battery tray.

[0062] After the grinding device 2 finishes grinding, the piston rod of the first cylinder 515 retracts, the second cylinder 518 extends, and the suction cup device 511 can adsorb the bottom plate of the battery tray, so that the battery tray can move with the movement of the lower pressure plate.

[0063] During the frame's flipping process, when it comes into contact with the horizontal surface, the frame's speed is relatively fast due to inertia, causing its flipping speed to exceed the output speed of the drive motor, thus affecting the motor's service life.

[0064] To avoid the above situation, an embodiment is provided, such as... Figure 11 As shown:

[0065] The grinding platform 1 is provided with a buffer device that acts on the frame 517 to slow down the rotation speed of the frame 517 toward the grinding platform 1.

[0066] The buffer device includes a base 71 and support rods 72 vertically arranged at both ends of the base 71. The grinding platform 1 has a U-shaped groove 73 in the vertical direction inside, and the U-shaped groove 73 is connected to the outside. The buffer device is arranged inside the U-shaped groove 73, and a compression spring 74 is provided between the base 71 and the bottom of the U-shaped groove 73. The connector 525 at the frame 517 and the U-shaped groove 73 are in a vertical plane, and the bend of the U-shaped groove 73 is located directly below the second rotating shaft 523.

[0067] Under normal conditions, the ends of the two support rods 72 are located outside the grinding platform 1. During the frame flipping process, when the frame is about to flip to the horizontal position, the support rods come into contact with the frame connectors, providing resistance and playing a buffering role, preventing the frame and grinding platform from coming into contact with each other and causing excessive impact.

[0068] The following provides one implementation of the drive mechanism, such as Figure 6 As shown:

[0069] The telescopic device uses a telescopic cylinder 31; the first moving device uses a rotary cylinder 32. The rotary cylinder 32 is set on the grinding platform 1, and the telescopic cylinder 31 is set at the end of the rotating arm 33 of the rotary cylinder 32. The telescopic cylinder 31 and the rotating arm 33 are vertically arranged in the vertical plane. The rotation angle of the rotating arm 33 is 90°, so that the rotating arm 33 rotates between a position perpendicular to the edge of the groove 11 and a position parallel to the edge of the groove 11.

[0070] In this embodiment, the telescopic device is equipped with a limiting device 4, which prevents the telescopic device from driving the grinding device 2 to continue moving downward after the grinding device 2 grinds away the polyurethane and electrophoretic layer at the insulation monitoring point, thereby controlling the grinding accuracy.

[0071] The limiting device 4 includes a cavity 41 with an open bottom and a first limiting plate 42 and a second limiting plate 43 disposed on the piston rod 311 of the telescopic cylinder 31. The cavity 41 encloses the grinding device 2 inside it. The top plate 44 of the cavity 41 is sleeved relative to the piston rod 311 of the telescopic cylinder 31, and the cavity 41 and the piston rod 311 are coaxially arranged. The first limiting plate 42 is located above the top plate 44, and the second limiting plate 43 is located below the top plate 44. The first limiting plate 42 and the second limiting plate 43 are arranged parallel to the top plate 44.

[0072] In the non-processing state, the top plate 44 of the cavity 41 is in contact with the second limiting plate 43, the distance between the top plate 44 and the first limiting plate 42 is d1, and the distance between the bottom of the grinding disc 22 and the plane where the bottom of the cavity 41 is located is d2; then, d1-d2=d, where d is the depth to which the grinding execution component grinds the surface of the workpiece.

[0073] In this embodiment, the polyurethane and electrophoretic layers are 0.8mm ± 0.1mm, therefore d is 1mm.

[0074] During the extension of the piston rod, the bottom of the cavity first contacts the bottom plate of the battery tray, then the piston rod continues to extend, the grinding disc contacts the polyurethane and electrophoretic layers, then the piston rod continues to extend, and then the top of the cavity contacts the second limiting plate, and the piston rod stops pressing down.

[0075] The 1mm thickness is slightly greater than the maximum process thickness of the polyurethane and electrophoretic layers. The polishing disc can completely polish the surface polyurethane and electrophoretic layers without excessive polishing of the aluminum sheet itself.

[0076] The cavity can also be made of transparent material, allowing workers to visually inspect the polishing process of the polishing disc. When the polyurethane and electrophoretic layers at the insulation monitoring point are polished away to expose the white aluminum sheet, it indicates that the polishing is complete. Workers can control the polishing disc to stop polishing via a control button. This method can be used as an alternative.

[0077] The piston rod 311 of the telescopic cylinder 31 is provided with a partition 45 above the first limiting plate 42. The partition 45 is horizontally arranged relative to the top plate 44 of the cavity 41. A spring 46 is provided between the partition 45 and the top plate 44 and is sleeved on the piston rod 311. The spring 46 wraps the first limiting plate 42 inside.

[0078] During the grinding process, the bottom of the cavity and the bottom plate of the battery tray remain sealed under the action of the spring, so that the powder generated during grinding is collected in the cavity, which can prevent powder pollution of the environment; at the same time, the elasticity of the spring plays a buffering role during the downward pressing of the cylinder, preventing the cylinder from pressing down too quickly, thereby improving the grinding quality.

[0079] In this embodiment, a dust removal device 6 is also included. The dust removal device 6 is an industrial vacuum cleaner, which is set below the grinding platform 1. The side wall of the cavity 41 is provided with a suction port 47. The industrial vacuum cleaner is connected to the suction port 47 through a hose 61, and the powder in the cavity is sucked away by the industrial vacuum cleaner.

[0080] The following provides an embodiment of the grinding device, such as Figure 7 and Figure 8 As shown:

[0081] The polishing device 2 includes a first motor 21 and a polishing disc 22 driven to rotate by the first motor 21; the first motor 21 is located at the end of the piston rod of the telescopic cylinder 31, and the two are coaxially arranged. When the battery tray is loaded, the rotating cylinder rotates the polishing device to the inside of the groove. After the battery tray is clamped and fixed by the lower pressure plate, the rotating cylinder rotates to move the polishing device directly above the insulation detection point, and then the surface of the bottom plate of the battery tray is polished.

[0082] The present invention also provides a specific embodiment of a rotary battery tray multi-point polishing system. The system is mainly used to polish multiple polishing points (insulation monitoring points) distributed on the parallel edges of the bottom plate of the battery tray at the same time, and can adjust the projection position of the polishing device on the horizontal plane according to the position changes of the polishing points (insulation monitoring points) on the battery tray.

[0083] The specific implementation method is as follows, including the rotary battery tray polishing equipment mentioned above. On this basis, each set of polishing points is provided with a polishing device 2 and a driving mechanism 3.

[0084] like Figure 5 As shown, multiple polishing devices 2 are respectively arranged on both sides of the rectangular groove 11, and the polishing devices 2 on the same side are distributed along a straight line.

[0085] To prevent the pressure plate from obstructing the grinding area of ​​the insulation monitoring points during the pressing process of the battery tray, a specific implementation method for the pressure plate is provided, such as... Figure 5 and Figure 9 As shown:

[0086] The lower pressure plate 51 has an I-shaped structure, including two sets of parallel first pressure plates 512 and second pressure plates 513, and a third pressure plate 514 that is perpendicularly connected to the first pressure plate 512 and the second pressure plate 513 respectively; wherein, the first pressure plate 512, the second pressure plate 513 and the third pressure plate 514 are used to apply pressure to the position of the non-insulated monitoring point on the battery tray.

[0087] When the pressure plate 51 applies pressure to the bottom plate of the battery tray, the insulation monitoring point is located between the first pressure plate 512 and the second pressure plate 513 to avoid obstructing the insulation monitoring point.

[0088] To enable the lower pressure plate to flip outside the grinding platform for material unloading, this application provides a specific embodiment of the second moving device, such as... Figures 2-4 As shown:

[0089] The frame 517 is a ┍┑ shaped frame with its opening facing the direction of the rotation axis of the frame 517, so as to avoid the frame 517 rubbing against the grinding device 2 during the flipping process.

[0090] In actual production, the locations of insulation monitoring points on the base plate of different types of battery trays may vary. To address this issue, this application also provides another implementation method, such as... Figures 6-8 As shown:

[0091] The grinding platform 1 corresponds to the position of the insulation monitoring point on the battery tray. A slide groove 34 is provided at a position parallel to the edge of the groove 11. The rotary cylinder 32 is set on the slide block 35, and the slide block 35 slides along the slide groove 34. Before processing the battery trays of the same batch, the position of the slide block is adjusted so that it is perpendicular to the slide groove with the line connecting the corresponding insulation monitoring point.

[0092] Meanwhile, the rotating arm is a telescopic structure, and the telescopic length of the rotating arm can be determined by bolts. The sliding groove 34 is equipped with a locking device that acts on the sliding block 35. The position of the sliding block can be fixed by bolts or by an electromagnet module. An electromagnet module is provided at the bottom of the sliding groove 34. The sliding block 35 is made of a magnetically attractable material. After the position of the sliding block 35 is determined, the electromagnet module is activated to attract the sliding block, so that the sliding block is fixed relative to the sliding groove.

[0093] In this embodiment, the lower part of the grinding platform 1 is the cabinet 16, and the dust removal device 6 and the electrical control cabinet 14 are both located inside the cabinet 16.

[0094] The grinding platform is equipped with several control buttons. The drive components in this device are controlled via the electrical control cabinet below the grinding platform, as follows.

[0095] First, based on the position of the insulation monitoring point on the battery tray, adjust the position of the corresponding grinding device in the chute and the length of the rotating arm so that the grinding device and the insulation monitoring point correspond one-to-one; in the initial state, the projection surface of the rotating arm of the rotary cylinder is located inside the chute, and the frame is located outside the grinding platform.

[0096] The worker first slides the battery tray from the feeding device along the ball bearings on the grinding platform into the groove;

[0097] Press the flip button, and the drive motor will start working, flipping the frame so that the frame and the entire grinding platform come into contact.

[0098] Pressing the electromagnetic button energizes the electromagnet module, fixing the grinding device relative to the slide and the frame relative to the grinding platform.

[0099] Press the clamping button, and the first cylinder extends, with the rubber pad at the end of its piston rod contacting the bottom plate of the battery tray;

[0100] Press the grinding button, the rotary cylinder rotates 90°, so that the rotating arm is perpendicular to the slide, the grinding device is directly above the insulation monitoring point, the telescopic cylinder begins to extend, and the grinding device starts at the same time, and the grinding operation is completed.

[0101] Press the reset button, and the telescopic cylinder, rotary cylinder, and first cylinder will reset in sequence;

[0102] Press the suction button, the second cylinder extends, so that the suction cup device contacts the bottom plate of the battery tray, and at the same time the suction cup device is activated to suction the battery tray.

[0103] Press the electromagnetic button to de-energize the electromagnet module;

[0104] Press the unloading button, and the drive motor will drive the frame to flip, moving the frame to the outside of the grinding platform. Throughout the process, the lower pressure plate will continuously hold the battery tray by the suction cup and keep it in a horizontal position. When the frame flips to the predetermined position, the suction cup will be de-energized, and the battery tray will fall onto the unloading conveyor. At the same time, the second cylinder will reset, completing the unloading process.

[0105] Then repeat the above steps.

[0106] The execution logic of the entire control system can also be controlled by a PLC controller, reducing the number of control buttons and further improving automation.

[0107] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
