Description

Technical Field

[0001] This utility model relates to a solvent tank opening mechanism. Background Technology

[0002] In lithium battery production workshops, the level of automation is becoming increasingly high, gradually achieving automation and unmanned operation. In particular, the upstream pulping process is highly automated, from the initial batching, automatic powder feeding, automatic powder weighing, automatic powder conveying to the mixer, automatic addition of solvent formula to the mixer, mixing to form a slurry, and automatic conveying of the slurry to the transfer tank at the head and tail of the coating machine for coating. This completes the process connection from pulping to sheeting of lithium battery cells. However, the front-end supply 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 problem of automatic suction, the first step is to solve the problem of opening the cap. The existing method of opening the cap is to manually hold the cap opening tool and insert it into the cross groove of the solvent tank cap to manually rotate the solvent tank cap until it is unscrewed. This process is not only cumbersome but also laborious.

[0003] The currently retrieved Chinese patent "A Mechanism for Opening a Material Bucket in a Cleaning Station" (publication number CN218145772U) includes two cylinders connected to a support frame. A nylon block and a proximity switch are connected to the support frame between the two cylinders. The left end of the support frame is connected to the flipping end of a pneumatic actuator with a fork. The fixed end of the pneumatic actuator passes through a square tube and is connected to a stainless steel cover. The upper end of the square tube is connected to a mounting flange, and the side wall of the square tube is connected to the stainless steel cover. A mechanical stop is connected to the left side wall of the support frame. Although this mechanism overcomes the problem of requiring manual intervention for the upper lid of the IBC (Integrated Circuit) of existing cleaning material turnover buckets, its structure differs from that of this application. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a solvent tank opening mechanism to realize mechanized opening and avoid the harm to the health of operators caused by the odor and volatility of solvent materials.

[0005] The technical solution of this utility model:

[0006] This utility model's solvent tank opening mechanism includes a base plate fixed on a movable seat and a slide block slidably connected to the base plate. The slide block is driven to move by an up-and-down moving cylinder mounted on the base plate. A rotating rod is mounted on the slide block, and a solvent tank lid positioning cover is mounted on the free end of the rotating rod. The inner end of the rotating rod is connected to the output end of a rotary motor. The end face of the solvent tank lid positioning cover is provided with a Phillips screwdriver bit and a solvent tank lid suction cup. The negative pressure hole on the solvent tank lid suction cup is connected to a negative pressure pipeline and a vacuum pump.

[0007] Preferably, the rotating rod body is provided with a channel communicating with the negative pressure hole, and the rotating rod is provided with a vacuum inlet communicating with the channel.

[0008] Preferably, the slide block is equipped with a guide rod and a sliding sleeve fitted on the guide rod, and a push plate is installed on the sliding sleeve. The push plate is driven to move by a capping bit pressing cylinder installed on the slide block, and the housing of the rotary motor is fixed on the push plate.

[0009] Preferably, a support frame is installed on the slide block, and the support frame is provided with a hole for supporting the guide rotating rod. The rotating rod is connected to the output end of the rotary motor through a coupling.

[0010] Preferably, a limiting block is fixedly installed on the slide block, and a compression spring is installed between the limiting block and the push plate. The compression spring provides a pre-tightening pressure to the push plate, the rotating rod, and the solvent tank lid positioning cover towards the solvent tank lid.

[0011] The working method of the solvent tank opening mechanism of this utility model.

[0012] During operation, the up-and-down moving cylinder drives the slide, rotating rod, and solvent container lid suction cup to move downwards, so that the Phillips capping bit on the solvent container lid suction cup can be inserted into the Phillips groove of the solvent container lid. At this time, the rotary motor starts working, driving the rotating rod, solvent container lid suction cup, and Phillips capping bit to rotate, thus loosening the lid. Then, under the action of the vacuum pump, the negative pressure hole adsorbs the lid under negative pressure. Next, the up-and-down moving cylinder drives the slide, rotating rod, solvent container lid suction cup, and the adsorbed lid to move upwards, thus completing the entire opening process. When it is necessary to close the lid, the process is reversed as described above, thus completing the closing process. Attached Figure Description

[0016] 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.

[0017] In order to open the solvent tank lid, the solvent tank lid opening mechanism A of this application includes a base plate A1 and a slide block A2 slidably connected to the base plate. A slide rail is provided on the base plate, and a slide groove that slides and engages with the slide rail is provided on the bottom surface of the slide block A2. The slide block A2 is driven to move by an up-and-down moving cylinder A3 mounted on the base plate.

[0018] A rotating rod A4 is mounted on the slide A2. A solvent container cap positioning cover A5 is mounted on the free end of the rotating rod A4. The inner end of the rotating rod A4 (relative to the free end) is connected to the output end of the rotary motor A6. When the rotary motor A6 rotates, it drives the rotating rod A4 and the solvent container cap positioning cover A5 to rotate. The end face of the solvent container cap positioning cover A5 is provided with a Phillips screwdriver bit A7 and a solvent container cap suction cup A8. The negative pressure hole A9 on the solvent container cap suction cup A8 is connected to the negative pressure pipeline and the vacuum pump. During operation, the up-and-down moving cylinder A3 drives the slide A2, the rotating rod A4, and the solvent container cap suction cup A8 to move downwards, so that the solvent container cap suction cup A8... The Phillips head capping bit A7 is inserted into the Phillips head groove of the solvent container lid. At this time, the rotary motor A6 (which is a servo motor that provides power to the Phillips head capping bit A7 and can precisely control the number of rotations of the Phillips head capping bit) starts working, driving the rotating rod A4, the solvent container lid suction cup A8, and the Phillips head capping bit A7 to rotate, thus loosening the lid. Then, under the action of the vacuum pump, the negative pressure hole A9 performs negative pressure adsorption on the lid. Next, the up-and-down moving cylinder A3 drives the slide A2, the rotating rod A4, the solvent container lid suction cup A8, and the adsorbed lid to move upward, realizing the entire lid opening process. When it is necessary to close the lid, the process is reversed as described above, thus realizing the lid closing process.

[0019] For a reasonable design, the rotating rod A4 has a channel that communicates with the negative pressure hole A9. The rotating rod has a vacuum inlet A10 that communicates with the channel. The vacuum inlet A10 is connected to the vacuum pump through a negative pressure pipeline.

[0020] For stable and reliable installation, a guide rod A11 and a sleeve A12 fitted on the guide rod are installed on the slide A2. A push plate A13 is installed on the sleeve A12. The push plate A13 is driven to move by a capping bit pressing cylinder A19 installed on the slide. The housing of the rotary motor A6 is fixed on the push plate A13. A support frame A14 is installed on the slide A2. The support frame A14 is provided with a hole A15 for supporting the guide rotating rod. The rotating rod is connected to the output end of the rotary motor A6 through a coupling A16.

[0021] In addition, a limiting block A17 is fixedly installed on the slide block. A compression spring A18 is installed between the limiting block A17 and the push plate A13. The compression spring provides the push plate, the rotating rod and the solvent container lid positioning cover with pre-tightening pressure on the solvent container lid. The compression spring A18 realizes the spring buffer and pre-pressure function, so that the Phillips screwdriver bit and the solvent container lid can always be in contact.

[0022] The solvent container opening mechanism A of this application can automatically open and close the solvent container lid, realizing unmanned opening and closing of the solvent container lid, which not only saves manpower but also simplifies the process.

[0023] 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.
