Description

Technical Field

[0001] This utility model relates to the field of lithium battery production equipment technology, specifically to a uniform coating mechanism for a lithium battery coating machine. Background Technology

[0002] Currently, lithium batteries, as an emerging energy source, are widely used, especially in mobile communication digital products and new energy vehicles. Lithium battery manufacturing equipment is constantly being improved and updated, and the coating process for lithium battery electrodes is a crucial step in lithium battery production; the quality of the coating greatly affects battery safety.

[0003] Existing lithium battery coating machines have the following drawbacks during use: In conventional coating mechanisms, slurry is injected through individual orifices. When the slurry accumulates in the accumulation chamber, there is more slurry in the middle and less on the sides, resulting in higher internal pressure during coating in the middle, affecting the volume ratio of the slurry. The slurry flow rate also differs between the middle and the sides, leading to uneven coating. In addition, when the ambient temperature is low, the surface temperature of the substrate is low, affecting the adhesion of the coating and also causing uneven coating. Therefore, there is room for improvement. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows: a uniform coating mechanism for a lithium battery coating machine, comprising: a main body mechanism and a temperature control mechanism. The main body mechanism includes a material accumulation frame, a guide roller rotatably mounted on the inner wall of the material accumulation frame, a coating roller rotatably mounted on the inner wall of the material accumulation roller, a guide rail fixed to the top of the material accumulation frame, a sliding seat slidably mounted on the guide rail, a driving component mounted on the guide rail and passing through the sliding seat, a storage cylinder fixed to the top of the sliding seat, and a feeding component mounted on one side of the storage cylinder.

[0006] The temperature control mechanism includes a V-shaped seat with its ends fixed to the inner sides of the material accumulation frame, a first guide roller installed on one side of the V-shaped seat, a second guide roller installed on one side of the V-shaped seat, and multiple sets of electric heating tubes fixed on the V-shaped seat.

[0007] In a preferred embodiment, the present invention can be further configured as follows: the guide rail includes a rectangular seat symmetrically fixed to the top of the material accumulation frame and a round rod symmetrically arranged and connected to the opposite rectangular seat; the sliding seat has symmetrically opened round holes, and the round holes are slidably fitted into the round rods.

[0008] In a preferred embodiment, the present invention can be further configured such that: the driving component includes a reciprocating screw rotatably mounted between opposing rectangular seats and a motor fixed on one side of the rectangular seat with its shaft fixedly connected to the end of the reciprocating screw; the sliding seat has a threaded hole, and the reciprocating screw meshes with the threaded hole.

[0009] In a preferred embodiment, the present invention can be further configured such that the feeding component includes a discharge pipe whose end communicates with the inner cavity of the storage cylinder and an electric valve installed on the discharge pipe.

[0010] In a preferred embodiment, the present invention can be further configured such that: multiple rectangular grooves are opened on the outer side of the V-shaped seat, and the heating tubes are fixed in an array on the inner wall of the rectangular grooves.

[0011] In a preferred embodiment, the present invention can be further configured such that a sealing cap is installed at the top of the storage cylinder via a threaded connection.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. In this utility model, a guide rail is fixed at the top of the material accumulation frame, and a sliding seat is slidably installed on the guide rail. The sliding seat is driven to reciprocate by a driving component. A storage cylinder is fixed at the top of the sliding seat to store the coating material, and a feeding component is installed on one side of the storage cylinder.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example 1: Combination Figure 1-4 As shown, this embodiment provides a uniform coating mechanism for a lithium battery coating machine, including: a main body mechanism 100 and a temperature control mechanism 200.

[0018] The main body 100 includes a material collection frame 110, a guide roller 120 rotatably mounted on the inner wall of the material collection frame 110, a coating roller 130 rotatably mounted on the inner wall of the material collection roller, a guide rail 140 fixed to the top of the material collection frame 110, a sliding seat 150 slidably mounted on the guide rail 140, a drive member 160 mounted on the guide rail 140 and passing through the sliding seat 150, a storage cylinder 170 fixed to the top of the sliding seat 150, and a delivery member 180 mounted on one side of the storage cylinder 170.

[0019] The material collection frame 110 is used to place the paint required for coating. When the substrate passes through the paint, the paint adheres to the substrate, thus achieving coating. The guide roller 120 is used to guide the substrate so that it adheres tightly to the inner bottom wall of the material collection frame 110. The coating roller 130 is used to scrape off excess paint from the substrate, control the coating thickness, and ensure the flatness of the paint covering the substrate.

[0020] The guide rail 140 is used to mount the sliding seat 150 and limit the movement of the sliding seat 150. The guide rail 140 includes a rectangular seat 141 symmetrically fixed to the top of the material collection frame 110 and a round rod 142 symmetrically arranged and connected to the rectangular seat 141. Circular holes 151 are symmetrically opened on the sliding seat 150. The circular holes 151 are slidably fitted into the round rod 142, so that the sliding seat 150 can move stably.

[0021] The drive unit 160 includes a reciprocating screw 161 rotatably mounted between the opposite rectangular seats 141 and a motor 162 fixed on one side of the rectangular seat 141 with its shaft fixedly connected to the end of the reciprocating screw 161. A threaded hole 152 is opened on the sliding seat 150, and the reciprocating screw 161 meshes with the threaded hole 152. With this arrangement, when the motor 162 starts, it drives the reciprocating screw 161 to rotate. The reciprocating screw 161 rotates in the threaded hole 152, which drives the sliding seat 150 to reciprocate, thereby driving the storage and delivery unit 180 to reciprocate, and uniformly feeding the paint into the accumulation frame 110.

[0022] The storage cylinder 170 is fixed to the top of the sliding seat 150 and is used to store paint. The top of the storage cylinder 170 is fitted with a sealing cap by a threaded connection to seal the storage cylinder 170 and to facilitate the user to add paint to the storage cylinder 170.

[0023] The delivery unit 180 includes a discharge pipe 181 whose end communicates with the inner cavity of the storage cylinder 170 and an electric valve 182 installed on the discharge pipe 181. The discharge pipe 181 is used to deliver the paint in the storage cylinder 170, and the electric valve 182 is used to control the opening and closing of the discharge pipe 181.

[0024] The temperature control mechanism 200 includes a V-shaped seat 210 with its end fixed on the opposite inner side of the material collection frame 110, a first guide roller 220 installed on one side of the V-shaped seat 210, a second guide roller 230 installed on one side of the V-shaped seat 210, and multiple sets of electric heating tubes 240 fixed on the V-shaped seat 210.

[0025] The end of the V-shaped seat 210 is fixed to the inner wall of the material accumulation frame 110 to ensure the stability of the V-shaped seat 210. The first guide roller 220 and the second guide roller 230 are both used to guide the substrate. Multiple rectangular grooves are opened on the outer side of the V-shaped seat 210. The heating tubes 240 are fixed in an array on the inner wall of the rectangular grooves. Through this setting, the substrate can be preheated before the coating operation, thereby increasing the surface temperature of the substrate and ensuring the adhesion of the substrate during the coating process.

[0026] The working principle and usage process of this utility model are as follows: In use, the substrate is passed sequentially around the second guide roller 230 and the first guide roller 220, and along the bottom wall of the accumulation frame 110 through the coating roller 130 and the guide roller 120. The coating is poured into the storage cylinder 170. The electric valve 182 is opened. At this time, the coating in the storage cylinder 170 falls into the accumulation frame 110 through the discharge pipe 181 and accumulates on the surface of the substrate for coating. At the same time, the motor 162 is started, driving the reciprocating screw 161 to rotate. The rotation of the reciprocating screw 161 drives the sliding seat 150 to move back and forth. The movement of the sliding seat 150 drives the storage cylinder 170 and the discharge pipe 181 to move back and forth, so as to evenly feed the coating into the accumulation frame 110. In addition, the electric heating tube 240 is started to preheat the surface of the substrate before coating, thereby increasing the surface temperature of the substrate.

[0027] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
