Description

Technical Field

[0001] This utility model relates to a device used in lithium battery production processes, and in particular to a solvent tank inner and outer lid opening mechanism. Background Technology

[0002] In lithium battery production workshops, the level of automation is getting higher and higher, and automation and unmanned operation have been gradually realized, especially in the upstream pulping process. From the batching, powder is automatically added, the powder is automatically weighed, the powder is automatically transported to the mixer, the solvent formula is automatically added to the mixer, the mixer is stirred to make slurry, and the slurry is automatically transported to the transfer tanks at the head and tail of the coating machine for coating. This completes the process connection from pulping to sheet making of lithium battery cells.

[0003] However, the front-end feeding of the solvent dispensing system still requires manual suction to feed the solvent into the metering tank of the automatic solvent dispensing system. Then the automatic solvent dispensing system delivers the solvent to the mixer according to the ratio. To solve the automatic suction problem, the automatic cap opening problem must be solved first.

[0004] The 200L solvent container has two lids. The inner lid is a sealed lid with a threaded lock and a sealing ring. It has a cross-shaped groove on the back for easy unscrewing and is reusable. The outer lid is a dustproof and waterproof lid with a snap-on design. Once locked, it cannot be easily opened and requires destructive opening, which will damage the outer lid in the process. Therefore, it is a single-use lid and cannot be reused. The outer lid of the 200L solvent container has two grooves and a small tail. To open the outer lid manually, you first need to cut the two grooves with a knife, then pull the small tail between the two grooves to open the outer lid into a V-shape. The snap on the outer lid will then easily disengage, allowing you to open the outer lid. Then, you need to use a special tool to unscrew the inner lid. This process is not only tedious and laborious, but also easily injures the hands of the person opening the inner and outer lids.

[0005] The applicant's prior application, a solvent feeding and suction device (publication number CN221296088U), includes a solvent tank opening mechanism that can remove the inner lid, but cannot open the solvent tank with both inner and outer lids. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a solvent tank opening mechanism that can easily open the outer and inner lids of the solvent tank, realizing unmanned opening of the inner and outer lids of the solvent tank.

[0007] The present invention relates to a solvent tank inner and outer lid opening mechanism, characterized in that: it includes an inner and outer lid opening mechanism mounting base, an inner and outer lid opening mechanism lifting motor fixedly mounted on the inner and outer lid opening mechanism mounting base, and an inner and outer lid opening mechanism driven by the inner and outer lid opening mechanism lifting motor and slidably connected to the inner and outer lid opening mechanism mounting base. The inner and outer lid opening mechanism is fixedly provided with a lid opening motor and a lid opening motor reducer connected in sequence. The output end of the lid opening motor reducer is connected to a discharge block and two lid opening cylinders fixed on the discharge block and arranged in opposite directions. The extension and retraction ends of the two lid opening cylinders are equipped with claws that can penetrate the outer lid.

[0008] Preferably, the sliding plate of the inner and outer cover opening mechanism is slidably installed on the mounting base of the inner and outer cover opening mechanism, the inner and outer cover opening mechanism is provided on the sliding plate of the inner and outer cover opening mechanism, and the output end of the lifting motor of the inner and outer cover opening mechanism is connected to the lifting screw nut mechanism to drive the sliding plate of the inner and outer cover opening mechanism to slide.

[0009] Preferably, the slide plate of the above-mentioned inner and outer cover opening mechanism is provided with a first end plate and a second end plate. The nut of the lifting screw nut mechanism is fixedly installed on the first end plate. The cover opening spring buffer mechanism is installed between the first end plate and the second end plate. The cover opening spring buffer mechanism is equipped with a movable plate that can be lifted and moved. The cover opening motor and the cover opening motor reducer are fixedly installed on the movable plate. The output end of the cover opening motor reducer passes through the second end plate and is connected to the unloading block.

[0010] Preferably, the unloading block is slidably connected to an unloading cover plate, which includes two side portions and a middle connecting portion connecting the two side portions, the middle connecting portion passing between two cutting claws.

[0011] Preferably, the unloading block is provided with a slide rail, through which a slide rod is connected at its lower end to the unloading cover plate, the upper end of the slide rod is connected to the unloading cover push plate, and an unloading cover spring is sleeved on the slide rod between the unloading cover push plate and the unloading block.

[0012] Preferably, the above-mentioned unloading push plate has a through hole in the center, and a rotating shaft is inserted through the through hole. The lower end of the rotating shaft is fixedly connected to the unloading block, and the upper end of the rotating shaft is connected to the output end of the unloading motor reducer through a coupling.

[0013] Preferably, a pneumatic slip ring is connected to the second end plate. The fixed ring of the pneumatic slip ring is fixed to the lower surface of the second end plate. The movable ring of the pneumatic slip ring rotates relative to the fixed ring. The fixed ring of the pneumatic slip ring is provided with a first interface for an external air source pipeline to enter. The movable ring of the pneumatic slip ring is provided with a second interface for connecting the air supply pipeline of the cover-opening cylinder. The rotating shaft is a non-circular cross-section shaft. The center of the fixed ring of the pneumatic slip ring has a channel for the rotating shaft to pass through (so that the rotation of the rotating shaft will not drive the fixed ring of the pneumatic slip ring to rotate). The center of the movable ring of the pneumatic slip ring has a through hole that rotates synchronously with the rotating shaft (so that the rotation of the rotating shaft can drive the movable ring of the pneumatic slip ring to rotate).

[0014] Preferably, a cap removal cylinder is installed on the first end plate. The free end of the cap removal cylinder connecting rod connected to the output end of the cap removal cylinder is connected to the movable plate so as to drive the cap opening motor reducer, rotating shaft, unloading block and cap removal push plate to rise when the cap removal cylinder retracts. During the rising process, the cap removal push plate is blocked by the pneumatic slip ring, which forces the cap removal plate to fall off the unloading block to remove the outer cap stuck on the cutter claw.

[0015] Preferably, the initial distance between the two cutting claws is less than the length of the straight groove in the cross groove of the inner cover, and the two cutting claws are relatively far apart under the drive of the opening cylinder so that the two cutting claws press against the wall of the straight groove in the cross groove of the inner cover.

[0016] Preferably, the above-mentioned cover-opening spring buffer mechanism includes a cover-opening motor guide shaft, a cover-opening motor guide bearing and a spring that are slidably connected to the cover-opening motor guide shaft. The cover-opening motor guide bearing is fixed on a movable plate, and the spring is sleeved on the cover-opening motor guide shaft with one end abutting against the first end plate and the other end abutting against the cover-opening motor guide bearing.

[0017] The working principle of the solvent container inner and outer lid opening mechanism of this utility model is as follows:

[0018] In operation, machine vision is used to photograph and locate the position of the 200L solvent tank's outer lid. Then, the XY module of the automatic suction device moves to directly above the 200L solvent tank's outer lid (this is existing technology and will not be elaborated upon here). At this point, the inner and outer lid opening mechanism moves downwards under the drive of the outer lid opening mechanism's lifting motor and lifting screw nut mechanism. Simultaneously, the lid opening motor starts working, and the cutting claw pierces into the 200L solvent tank's outer lid and rotates into the inner lid. At this time, the two lid opening cylinders open and press against the inner wall of the cross groove, cooperating with the gravity of the 200L solvent tank (heavier solvent tanks will not rotate). The operation of the lid opening motor, through the lid opening motor reducer, coupling, rotating shaft, unloading block, lid opening cylinder, and cutting claw, drives the inner lid to rotate, causing the inner and outer lids to spiral in the same direction. The barrel lid is opened, and then the inner and outer lid opening mechanism moves upward under the drive of the lifting motor and lifting screw nut mechanism of the outer lid opening mechanism, so that the inner and outer lids of the 200L solvent barrel can be removed; wait for the suction device to suck up the material (the existing technology will not be described in detail here), and move again to the top of the barrel opening to rotate the inner lid back (by the opposite rotation direction of the aforementioned lid opening motor); then, under the action of the XY module of the automatic suction device, move to the cap removal position (i.e. above the waste outer lid storage area). The cap removal cylinder drives the rotating shaft, cap removal push plate and unloading block to move upward through the cap removal cylinder connecting rod. The cap removal push plate is blocked by the pneumatic slip ring, and drives the cap removal plate downward to push the outer lid through the sliding rod, so that the outer lid is disengaged from the cutter and falls off, thus completing one complete inner and outer lid opening action.

[0019] This utility model's solvent container opening mechanism allows for easy opening of both the outer and inner lids of the solvent container, enabling unmanned operation and simplifying the process. Attached Figure Description

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be pointed out that the following detailed description is exemplary and intended to provide further explanation of the present application; unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] The solvent tank inner and outer lid opening mechanism of this utility model includes an inner and outer lid opening mechanism mounting base 2, which is installed on an automatic feeding device (such as the applicant's prior application: Solvent Feeding and Feeding Device - CN221296088U). In use, the position of the outer lid of the 200L solvent tank is located by taking pictures through machine vision, and then the XY module of the automatic feeding device is used to move it to the top of the outer lid of the 200L solvent tank (the movement of the automatic feeding device through the XY module is a conventional technology, and its mechanism and working principle will not be described in detail here).

[0028] The inner and outer cover opening mechanism mounting base 2 is fixedly installed with an inner and outer cover opening mechanism lifting motor 1 and an inner and outer cover opening mechanism 4 driven by the inner and outer cover opening mechanism lifting motor 1 and slidably connected to the inner and outer cover opening mechanism mounting base 2. Specifically, an inner and outer cover opening mechanism slide plate 41 is slidably installed on the inner and outer cover opening mechanism mounting base 2, and the inner and outer cover opening mechanism 4 is located on the inner and outer cover opening mechanism slide plate 41. The output end of the inner and outer cover opening mechanism lifting motor 1 is connected to the lifting screw nut mechanism 3 to drive the inner and outer cover opening mechanism slide plate 41 to slide.

[0029] The inner and outer cover opening mechanism 4 is fixedly equipped with an opening motor 6 and an opening motor reducer 10 connected in sequence. The output end of the opening motor reducer 10 is connected to a discharge block 18 and two opening cylinders 17 fixed on the discharge block 18 and arranged in opposite directions. The telescopic ends of the two opening cylinders 17 are equipped with claws 21 that can penetrate the outer cover A1. The outer cover A1 is made of thin plastic or aluminum alloy and other materials. The tips of the claws 21 have blades. After being pierced by the external force applied by the lifting motor 1 and the lifting screw nut mechanism 3 of the inner and outer cover opening mechanism, the two claws 21 open and press against the inner wall of the straight groove of the cross groove of the inner cover, so that the inner cover rotates under the action of the opening motor 6 and the opening motor reducer 10, so that the inner and outer covers spiral upward to open the barrel lid.

[0030] The initial distance between the two claws 21 is less than the length of a straight groove in the cross groove of the inner cover (the width of the two claws 21 is less than the width of the straight groove in the cross groove of the inner cover). The two claws 21 are relatively far apart under the drive of the opening cylinder 17 so that the two claws 21 press against the inner wall of the straight groove in the cross groove of the inner cover. After the claws 21 press against the inner cover, the rotation of the opening motor 6 can drive the claws 21 and the inner cover A2 to rotate synchronously. The opening motor reducer 10 drives the claws 21 to rotate at a speed of 0.1-1 revolution / second. The rotation speed is slow so as not to damage the inner cover. Similarly, the lifting motor 1 of the inner and outer cover opening mechanism drives the sliding plate 41 of the inner and outer cover opening mechanism to lift at a speed of 10-50 mm / second, which will not damage the inner cover.

[0031] Specifically, the sliding plate 41 of the inner and outer cover opening mechanism is provided with a first end plate 42 and a second end plate 43. The nut of the lifting screw nut mechanism 3 is fixedly installed on the first end plate. Driven by the lifting motor 1 of the inner and outer cover opening mechanism, the screw of the lifting screw nut mechanism 3 rotates, causing the first end plate 42 and the inner and outer cover opening mechanism on it to slide. The cover opening spring buffer mechanism 7 is installed between the first end plate 42 and the second end plate 43. The cover opening spring buffer mechanism 7 is equipped with a movable plate 44 that can be lifted and moved. The cover opening motor 6 and the cover opening motor reducer 10 are fixedly installed on the movable plate 44. The output end of the cover opening motor reducer 10 passes through the second end plate and is connected to the unloading block 18.

[0032] The cover-opening spring buffer mechanism 7 includes a cover-opening motor guide shaft 9, a cover-opening motor guide bearing 11 and a spring 71 that are slidably connected to the cover-opening motor guide shaft 9. The cover-opening motor guide bearing 11 is fixed on the movable plate 44, and the spring 71 is sleeved on the cover-opening motor guide shaft 9. One end of the spring 71 abuts against the first end plate 42, and the other end abuts against the cover-opening motor guide bearing 11. The motor guide bearing 11 makes the movement of the movable plate 44 smoother. The spring 71 plays a buffering and yielding role after the blade 21 presses against the inner cover.

[0033] The unloading block 18 is slidably connected to an unloading cover plate 20. The unloading cover plate 20 includes two side parts 201 and a middle connecting part 202 connecting the two side parts. The middle connecting part 202 passes between two cutting claws 21. When the unloading cover plate 20 is disengaged from the unloading block 18, the outer cover stuck on the cutting claws 21 can be disengaged through the middle connecting part 202, etc.

[0034] The specific structure of the lifting and sliding of the unloading plate 20 relative to the unloading block 18 is as follows: The unloading block 18 is provided with a slide rail 181, and a slide rod 182 connected to the unloading plate 20 at its lower end passes through the slide rail. The upper end of the slide rod is connected to the unloading push plate 16. An unloading spring 19 is sleeved on the slide rod between the unloading push plate 16 and the unloading block 18. When the rotating shaft 22, the unloading push plate 16 and the unloading block 18 are pulled up, and the unloading push plate 16 is blocked by the pneumatic slip ring 15, the unloading push plate 16 pushes the unloading plate 20 through the slide rod 182, so that the unloading plate 20 is disengaged from the unloading block 18.

[0035] The unloading push plate 16 has a through hole in the center, through which a rotating shaft 22 (the diameter of the through hole is larger than the diameter of the rotating shaft) is inserted. The lower end of the rotating shaft 22 is fixedly connected to the unloading block 18, and the upper end of the rotating shaft 22 is connected to the output end of the unloading motor reducer 10 via a coupling 12. An unloading cylinder 5 is installed on the first end plate 42. The output end of the unloading cylinder 5 is connected to the unloading cylinder connecting rod 8. The free end of the unloading cylinder connecting rod 8 is connected to the movable plate 44. When the unloading cylinder 5 retracts, it drives the unloading motor reducer 10, the rotating shaft 22, the unloading block 18, and the unloading push plate 16 to rise. During the rise of the unloading push plate 16, it is blocked by the pneumatic slip ring 15, which forces the unloading plate 20 to detach downward from the unloading block 18 to remove the outer cover stuck on the cutter claw 21.

[0036] A pneumatic slip ring 15 is connected to the second end plate 43. The pneumatic slip ring 15 is a commercially available part. The fixed ring 151 of the pneumatic slip ring 15 is fixed to the lower surface of the second end plate 43. The movable ring 152 of the pneumatic slip ring 15 rotates relative to the fixed ring. The fixed ring of the pneumatic slip ring 15 is provided with a first interface 153 for the external air source pipeline to enter. The movable ring of the pneumatic slip ring 15 is provided with a second interface 154 for the air supply pipeline to the cover opening cylinder 17. One end of the pipeline supplying air to the cover opening cylinder 17 is connected to the second interface 154, and the other end is connected to the air inlet end of the cover opening cylinder 17. The fixed ring of the pneumatic slip ring 15 can supply air to the movable ring of the pneumatic slip ring 15 from the internal channel when the movable ring of the pneumatic slip ring 15 rotates (this is prior art and will not be described in detail here), so that the air supply pipeline will not get tangled during the rotation of the cover opening cylinder 17.

[0037] The rotating shaft 22 is a non-circular cross-section shaft (such as a hexagonal or rectangular cross-section). The fixed ring of the pneumatic slip ring 15 has a channel 155 (the diameter of the channel is larger than the diameter of the cross-section of the rotating shaft 22) at its center, so that the rotation of the rotating shaft 22 will not drive the fixed ring of the pneumatic slip ring 15 to rotate. The movable ring of the pneumatic slip ring 15 has a through hole 156 (the size of the through hole is equivalent to the cross-sectional size of the rotating shaft 22) at its center, so that the rotation of the rotating shaft 22 can drive the movable ring of the pneumatic slip ring 15 to rotate synchronously.

[0038] The working principle of the solvent container inner and outer lid opening mechanism of this utility model is as follows:

[0039] In use, machine vision is used to photograph and locate the position of the 200L solvent tank's outer cover. Then, the XY module of the automatic suction device moves to directly above the 200L solvent tank's outer cover (this is existing technology and will not be elaborated here). At this time, the inner and outer cover opening mechanism 4 moves downward under the drive of the outer cover opening mechanism lifting motor 1 and the lifting screw nut mechanism 3. Simultaneously, the cover opening motor 6 starts working, and the cutter 21 pierces into the outer cover of the 200L solvent tank and rotates into the inner cover. At this time, the two cover opening cylinders 17 open and press against the inner wall of the cross groove, cooperating with the gravity of the 200L solvent tank (heavier solvent tanks will not rotate). At this time, the operation of the cover opening motor 6 drives the inner cover to rotate through the cover opening motor reducer 10, coupling 12, rotating shaft 22, unloading block 18, cover opening cylinder 17, and cutter 21, causing the inner and outer covers to spiral upward. Open the barrel lid, and then the inner and outer lid opening mechanism 4 moves upward under the drive of the outer lid opening mechanism lifting motor 1 and the lifting screw nut mechanism 3, so that the inner and outer lids of the 200L solvent barrel can be removed; wait for the suction device to suck up the material (the existing technology will not be described in detail here), and move again to the top of the barrel opening to rotate the inner lid back (by the opposite rotation direction of the aforementioned lid opening motor 6); then, under the action of the XY module of the automatic suction device, move to the cap removal position (i.e. above the waste outer lid storage area), and the cap removal cylinder 5 drives the rotating shaft 22, cap removal push plate 16 and unloading block 18 to move upward through the cap removal cylinder connecting rod 8. The cap removal push plate 16 is blocked by the pneumatic slip ring 15, and drives the cap removal plate 20 to push the outer lid downward through the slide rod 182, so that the outer lid is disengaged from the cutter claw 21 and falls down, thus completing one complete inner and outer lid opening action.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
