[0046] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model. In addition, it should be understood that the specific embodiments described herein are only used for illustrating and explaining the utility model, and are not used for limiting the utility model. In the utility model, the orientation words such as 'up' and 'down' are usually used for indicating the up and down in the actual use or working state of the device, and the specific is the drawing direction in the drawings; and 'inner' and 'outer' are used for the contour of the device.

[0047] The liquid injection sleeve cup 400 of the battery is a key tool for injecting electrolyte in the battery manufacturing process, and the liquid injection sleeve cup 400 usually comprises a cup body with an inner cavity, a soft sealing body is fixed at the bottom of the cup body and is used for sealing with the top of the battery. The cup body is also provided with a liquid injection needle tube, the liquid injection needle tube penetrates through the soft sealing body, the upper end of the liquid injection needle tube is communicated with the inner cavity of the cup body, and the lower end of the liquid injection needle tube extends out of the soft sealing body, so that the liquid injection needle tube can extend into the winding core of the battery during liquid injection.

[0048] In the present application, the nozzle 400a of the liquid injection sleeve cup 400 can only comprise the soft sealing body, the nozzle 400a can only comprise the liquid injection needle tube, and the liquid injection can comprise the soft sealing body and the liquid injection needle tube, and the specific structure of the nozzle 400a is not limited herein. Because in part of the sleeve cups, the soft sealing body and the liquid injection needle tube are detachable and can be cleaned separately. Therefore, when the nozzle 400a only comprises the soft sealing body, the cleaning mechanism of the present application only cleans the soft sealing body. When the nozzle 400a comprises the liquid injection needle tube, the cleaning mechanism of the present application only cleans the liquid injection needle tube. When the nozzle 400a comprises the soft sealing body and the liquid injection needle tube, the cleaning mechanism of the present application simultaneously cleans the liquid injection needle tube and the soft sealing body.

[0049] The present application provides a battery production equipment for producing a battery. In the process of producing the battery, a cleaning process of the injection cup 400 is included. The battery production equipment includes a cleaning device 1000, which plays a cleaning role of cleaning the nozzle 400a of the injection cup 400 in the cleaning process of the injection cup 400.

[0050] Referring to Figure 1 The present application provides a cleaning device 1000 for cleaning the nozzle 400a of the injection cup 400. The cleaning device 1000 includes a nozzle cleaning mechanism 100, a first clamping mechanism 200, and a second clamping mechanism 300.

[0051] Referring to Figure 2 The transmission path of the first clamping mechanism 200 sequentially passes through the incoming material station K1 and the cleaning station K2, and is used to transport the uncleaned injection cup 400 from the incoming material station K1 to the cleaning station K2.

[0052] The transmission path of the second clamping mechanism 300 sequentially passes through the cleaning station K2 and the feeding station K3, and is used to transport the cleaned injection cup 400 from the cleaning station K2 to the feeding station K3.

[0053] The nozzle cleaning mechanism 100 is arranged at the cleaning station K2, and is used to clean the nozzle 400a of the injection cup 400.

[0054] In the present embodiment, after the uncleaned injection cup 400 is transported to the incoming material station K1, the first clamping mechanism 200 is lowered from above the incoming material station K1 to the incoming material station K1, clamps the uncleaned injection cup 400, and then is raised to above the incoming material station K1 and moved to above the cleaning station K2. The first clamping mechanism 200 is lowered to the cleaning station K2, and the nozzle cleaning mechanism 100 cleans and dries the nozzle 400a of the injection cup 400. After the drying of the nozzle 400a of the injection cup 400 is completed, the first clamping mechanism 200 releases the injection cup 400 and is raised to above the cleaning station K2, and then is moved from above the cleaning station K2 to above the incoming material station K1.

[0055] After the first clamping mechanism 200 releases the liquid injection sleeve cup 400, the second clamping mechanism 300 moves from above the feeding station K3 to above the cleaning station K2, and then descends to the cleaning station K2 to clamp the liquid injection sleeve cup 400 released by the first clamping mechanism 200. After clamping the liquid injection sleeve cup 400, the second clamping mechanism 300 ascends from the cleaning station K2 to above the cleaning station K2, and then moves to above the feeding station K3. The second clamping mechanism 300 descends from above the feeding station K3 to the feeding station K3, and then releases the clamped liquid injection sleeve cup 400. The liquid injection sleeve cup 400 is transported from the feeding station K3 to the next process. Please refer to Figure 3 , Figure 3 The schematic diagram of the liquid injection sleeve cup 400 required by the present application.

[0056] Specifically, the first clamping mechanism 200 includes a first vertical driving member, a first clamping member, and a first horizontal driving member.

[0057] A plurality of liquid injection sleeve cups 400 are loaded in the sleeve cup tray and transported to the incoming material station K1.

[0058] The first vertical driving member drives the first clamping member to descend. When the buckle of the first clamping member is aligned with the clamping groove on both sides of the sleeve cup tray, two air cylinders are arranged on the left and right sides of the first clamping member to drive the first clamping member to clamp the sleeve cup tray inward from the left and right sides. The clamping part of the first clamping member is also provided with a buffer and polypropylene plastic to avoid clamping damage to the sleeve cup tray. After clamping, the first vertical driving member drives the first clamping member to ascend to above the incoming material station K1.

[0059] After the first horizontal driving member drives the first clamping member to move to above the cleaning station K2 in the horizontal direction, the first vertical driving member drives the first clamping member to descend to the cleaning station K2.

[0060] The second clamping mechanism 300 includes a second vertical driving member, a second clamping member, and a second horizontal driving member. The clamping process of the second clamping mechanism 300 is similar to that of the first clamping mechanism 200, and will not be described here.

[0061] Please refer to Figure 4 The present application provides a nozzle cleaning mechanism 100, which includes a cleaning assembly 10 and a drying assembly 20.

[0062] The cleaning assembly 10 is configured to clean the nozzle 400a of the liquid injection sleeve cup 400. The drying assembly 20 is formed with a drying cavity 21a. The drying cavity 21a is configured to accommodate the nozzle 400a of the liquid injection sleeve cup 400, and is used to access an external negative pressure mechanism to form a negative pressure environment in the drying cavity 21a.

[0063] In the embodiment of the utility model, through setting the drying assembly 20 which forms drying cavity 21a inside, after the nozzle 400a of the liquid injection sleeve cup 400 is cleaned, the nozzle 400a of the liquid injection sleeve cup 400 can be dried quickly in the negative pressure environment by connecting the external negative pressure mechanism through the drying cavity 21a, the residual electrolyte attached to the nozzle 400a can be separated by negative pressure, the cleaning effect of the nozzle cleaning mechanism 100 can be improved, thereby improving the technical problem that the nozzle cleaning mechanism 100 has poor cleaning effect on the liquid injection sleeve cup 400.

[0064] Please refer to Figure 5 Optionally, the cleaning assembly 10 comprises a second communication unit 11 and a sensor 12.

[0065] The top of the second communication unit 11 is formed with a cleaning tank 11a. The cleaning tank 11a extends along the first direction D1. The cleaning tank 11a is configured to accommodate cleaning liquid to soak the nozzle 400a of the liquid injection sleeve cup 400. The sensor 12 is used to detect the liquid level of the cleaning liquid in the cleaning tank 11a.

[0066] In the embodiment, the cleaning tank 11a is used to accommodate cleaning liquid. The cleaning liquid is used to soak the nozzle 400a of the liquid injection sleeve cup 400, thereby playing a cleaning role on the nozzle 400a of the liquid injection sleeve cup 400. The cleaning liquid can be an organic solvent such as ethanol, acetone, ethyl acetate, dimethyl carbonate (DMC), or an inorganic solvent, which is not limited here.

[0067] In the embodiment, since the first clamping mechanism 200 clamps multiple liquid injection sleeve cups 400 at a time. Therefore, the cleaning tank 11a extends along the first direction D1. The first clamping mechanism 200 soaks the nozzles 400a of the multiple liquid injection sleeve cups 400 arranged in a column along the first direction D1 in the cleaning tank 11a, thereby realizing the one-time cleaning of the nozzles 400a of the multiple liquid injection sleeve cups 400 and improving the cleaning efficiency.

[0068] In the embodiment, after the liquid injection sleeve cups 400 are soaked, part of the cleaning liquid will adhere to the outer surface of the nozzle 400a of the liquid injection sleeve cup 400. After multiple cleanings, the liquid level of the cleaning liquid in the cleaning tank 11a will decrease. If the cleaning liquid is not replenished in time, the liquid level of the cleaning liquid in the cleaning tank 11a will be insufficient to immerse the nozzle 400a, resulting in a decrease in cleaning effect.

[0069] Therefore, the cleaning assembly 10 of the embodiment further comprises a sensor 12. The sensor 12 is used to detect the liquid level of the cleaning liquid in the cleaning tank 11a. When the liquid level of the cleaning liquid is lower than a preset value, the sensor 12 can obtain this information. The staff can replenish the cleaning liquid according to the information, or automatically replenish the cleaning liquid by program control, which is not limited here.

[0070] Optionally, the sensor 12 can be a non-contact sensor 12, such as an ultrasonic liquid level sensor 12, a radar liquid level sensor 12, or a photoelectric liquid level sensor 12.

[0071] Optionally, the sensor 12 can be a contact sensor 12, such as a float ball liquid level sensor 12, a float cylinder liquid level sensor 12, a static pressure liquid level sensor 12, or a capacitive liquid level sensor 12. The type of the sensor 12 is not limited herein.

[0072] Optionally, the second communication unit 11 further comprises a liquid discharge port 11b at the bottom thereof. The liquid discharge port 11b is used to discharge the cleaning liquid when the cleaning liquid is replaced. The liquid discharge port 11b is in communication with the cleaning tank 11a.

[0073] Optionally, the drying cavity 21a of the present embodiment is formed by connecting an external negative pressure mechanism to form a negative pressure environment in the drying cavity 21a. The external negative pressure mechanism can be a structure such as an air extractor, an air pump, or a vacuum pump, and the type of the external negative pressure mechanism is not limited herein. It should be understood that the external negative pressure mechanism should not be understood as a part of the nozzle cleaning mechanism 100, and the external negative pressure mechanism only serves to provide an external negative pressure source.

[0074] Please refer to Figure 6 Optionally, the drying assembly 20 comprises a plurality of first accommodation units 21. The first accommodation unit 21 is formed with a drying cavity 21a.

[0075] In the present embodiment, one first accommodation unit 21 corresponds to one nozzle 400a. Because the drying nozzle 400a in the present embodiment is dried by forming a negative pressure environment in the drying cavity 21a to extract the cleaning liquid attached to the nozzle 400a, the design of one drying cavity 21a corresponding to one nozzle 400a can reduce the volume of each drying cavity 21a, so that the drying effect in the drying cavity 21a with a smaller volume is better when the negative pressure mechanism extracts the negative pressure, thereby realizing the rapid drying of the nozzle 400a in the negative pressure environment of the drying cavity 21a, and the residual electrolyte and cleaning liquid attached to the nozzle 400a are extracted by the negative pressure, thereby improving the cleaning effect of the nozzle cleaning mechanism 100 on the nozzle 400a.

[0076] During the process in which the first clamping mechanism 200 lowers the clamped plurality of liquid injection sleeve cups 400 to the cleaning station K2, the nozzle 400a of the liquid injection sleeve cup 400 first immerses into the cleaning tank 11a of the second communication unit 11 for a period of time. After the immersion is completed, the first clamping mechanism 200 drives the clamped plurality of liquid injection sleeve cups 400 to ascend by a distance.

[0077] The nozzle cleaning mechanism 100 further comprises a transfer assembly. The transfer assembly is configured to drive the cleaning assembly 10 and the drying assembly 20 to move in a second direction. The second direction and the first direction D1 are both horizontal directions, and the first direction D1 is perpendicular to the second direction.

[0078] After the soaking is completed, the first gripping mechanism 200 drives the gripped multiple liquid injection sleeves 400 to ascend by a distance. The transfer assembly drives the cleaning assembly 10 and the drying assembly 20 to move in the second direction, so that the cleaning assembly 10 is dislocated from the nozzles 400a of the multiple liquid injection sleeves 400, and the multiple first containing units 21 are respectively located below the nozzles 400a of the multiple liquid injection sleeves 400. At this time, the first gripping mechanism 200 drives the nozzles 400a of the cleaned liquid injection sleeves 400 to descend into the drying cavities 21a of the first containing units 21, and the nozzles 400a are dried in the negative pressure environment of the drying cavities 21a.

[0079] Optionally, referring to Figure 7 , the top of the first containing unit 21 is provided with a drying port 21b, which is in communication with the drying cavity 21a and is configured to insert the nozzle 400a of the liquid injection sleeve 400.

[0080] In the embodiment, the first gripping mechanism 200 drives the nozzle 400a of the liquid injection sleeve 400 to insert into the first containing unit 21 below from above the cleaning station K2, so that the drying port 21b is arranged at the top of the first containing unit 21 to facilitate the insertion of the nozzle 400a and improve the drying efficiency.

[0081] Optionally, referring to Figure 7 , the drying cavity 21a is configured to form a sealed space with the nozzle 400a of the accommodated liquid injection sleeve 400.

[0082] In the embodiment, when the first gripping mechanism 200 drives the gripped liquid injection sleeve 400 to descend into the drying cavity 21a of the first containing unit 21, the soft sealing body of the liquid injection sleeve 400 seals the drying port 21b. At this time, the top-opened drying cavity 21a forms a sealed space due to the sealing of the drying port 21b. When the external negative pressure mechanism extracts negative pressure, the moisture in the drying cavity 21a with limited volume and forming a sealed space is quickly extracted, so that the nozzle 400a is quickly dried.

[0083] Optionally, the drying assembly 20 further comprises a first communication unit 22, and a communication cavity 22a is formed in the first communication unit 22. The drying cavities 21a of the multiple first containing units 21 are in communication with one communication cavity 22a. The communication cavity 22a is configured to be connected to the external negative pressure mechanism.

[0084] In the embodiment, since each dry cavity 21a inside each first accommodating unit 21 is independent, if each dry cavity 21a is separately connected to an external negative pressure mechanism, the internal design of the drying assembly 20 and the external wiring design will be too complex. Therefore, the embodiment further provides a first communication unit 22. The first communication unit 22 is formed with a communication cavity 22a. The communication cavity 22a is in communication with the external negative pressure mechanism, and the dry cavities 21a of the plurality of first accommodating units 21 are respectively in communication with the same communication cavity 22a, so that one external negative pressure mechanism, through one first communication unit 22, realizes the negative pressure extraction of the plurality of first accommodating units 21, thereby reducing the complexity of the internal design of the drying assembly 20 and the complexity of the external wiring design. Since the plurality of first accommodating units 21 only need to be connected to one external negative pressure mechanism, the use cost of the nozzle cleaning mechanism 100 is reduced, and the cleaning cost of the liquid injection sleeve cup 400 is reduced.

[0085] Optionally, the surface of the first communication unit 22 is provided with a communication port 22b. The communication port 22b is in communication with the communication cavity 22a. The communication port 22b is configured to access the external negative pressure mechanism.

[0086] In the embodiment, the communication port 22b is in communication with the external negative pressure mechanism through a catheter or a trachea.

[0087] Optionally, the first communication unit 22 extends along a first direction D1. The plurality of first accommodating units 21 are arranged on the top of the same first communication unit 22 along the first direction D1.

[0088] In the embodiment, on the one hand, the residual electrolyte or cleaning liquid attached to the nozzle 400a inserted into the dry cavity 21a will be extracted by negative pressure, and the design of the plurality of first accommodating units 21 extending along the first direction can arrange more dry cavities 21a in a unit space to dry the nozzle 400a. On the other hand, since the first accommodating unit 21 is located on the top of the first communication unit 22, the residual electrolyte or cleaning liquid on the nozzle 400a will be affected by gravity and will be separated from the nozzle 400a faster during the drying process, thereby realizing the drying of the nozzle 400a and improving the drying efficiency.

[0089] Please refer to Figure 7 Optionally, the dry cavity 21a comprises a communication accommodating channel 21a1 and a dry channel 21a2. The accommodating channel 21a1 is in communication with the drying port 21b. The dry channel 21a2 is in communication with the communication cavity 22a. The accommodating channel 21a1 and the dry channel 21a2 extend along the thickness direction of the first accommodating unit 21. The inner diameter of the dry channel 21a2 is smaller than the inner diameter of the accommodating channel 21a1.

[0090] When the injection nozzle 400a to be cleaned includes a soft seal body and a liquid injection needle tube, the accommodation channel 21a1 is used to accommodate and dry the soft seal body, and the drying channel 21a2 is used to accommodate and dry the liquid injection needle tube, and since the outer diameter of the liquid injection needle tube is smaller than the outer diameter of the soft seal body, the inner diameter of the drying channel 21a2 is smaller than the inner diameter of the accommodation channel 21a1. Alternatively, the inner diameter of the drying channel 21a2 is greater than the outer diameter of the liquid injection needle tube to avoid the drying channel 21a2 being blocked, affecting the negative pressure extraction and reducing the drying efficiency.

[0091] When the injection nozzle 400a to be cleaned includes a soft seal body and a liquid injection needle tube, the accommodation channel 21a1 is used to accommodate and dry the soft seal body, and the drying channel 21a2 is used to accommodate and dry the liquid injection needle tube, and since the outer diameter of the liquid injection needle tube is smaller than the outer diameter of the soft seal body, the inner diameter of the drying channel 21a2 is smaller than the inner diameter of the accommodation channel 21a1. Alternatively, the inner diameter of the drying channel 21a2 is greater than the outer diameter of the liquid injection needle tube to avoid the drying channel 21a2 being blocked, affecting the negative pressure extraction and reducing the drying efficiency.

[0092] The above describes the embodiments of the present application in detail, and the principle and implementation mode of the present application are described by applying specific examples. The above embodiment is only used to help understand the method of the present application and its core idea. Meanwhile, for those skilled in the art, according to the principle of the present application, the specific implementation mode and application range will be changed, and the above description should not be understood as the limitation of the present application.
