[0036] like Figures 1 to 3 As shown, an embodiment of the utility model provides a side sliding device 3, which is used in a battery production system. The battery production system includes a frame 2 and a coating die 1; the side sliding device 3 includes: a mounting member 31, a sliding mechanism 32 and a driving mechanism 33; the mounting member 31 is used to install the coating die 1; the mounting member 31 is slidably mounted on the frame 2 through the sliding mechanism 32, and the driving mechanism 33 is transmission-connected with the mounting member 31; the mounting member 31 is driven to slide on the frame 2 by the driving mechanism 33, and the mounting member 31 can slide out of the frame 2 from the side of the frame 2.

[0037] The side sliding device 3 provided in this embodiment is applied to a battery production system, and the battery production system is used for lithium-ion battery production. The battery production system includes a coating die 1 and a frame 2, wherein the frame 2 is a steel structure frame, and the coating die 1 is arranged in the frame 2, and the coating die 1 is used to apply slurry on the surface of the current collector to obtain the pole piece of the lithium-ion battery. The frame 2 is in a strip shape, and the two sides along the length direction of the frame 2 are the sides of the frame 2. The current collector / pole piece is transported in the frame 2 along the length direction of the frame 2, and the frame 2 is also provided with structures such as detection equipment and a control unit.

[0038] The above-mentioned side sliding device 3 includes a mounting member 31, a side sliding mechanism and a driving mechanism 33. Among them, the mounting member 31 is used to install the coating die head 1, and the coating die head 1 can be installed on the mounting member 31 by means of structures such as bolts, screws, rivets or pins. The mounting member 31 is slidably mounted on the frame 2 through a sliding mechanism 32, so that the mounting member 31 can slide on the frame 2, and, by sliding the mounting member 31, the mounting member 31 can slide out of the frame 2 from the side of the frame 2. The driving mechanism 33 is transmission-connected with the mounting member 31, and is used to drive the mounting member 31 to slide on the frame 2.

[0039] During use, when the maintenance personnel need to inspect and repair the coating die head 1, the driving mechanism 33 drives the mounting member 31 to slide on the frame 2, and the mounting member 31 can slide out of the frame 2 from the side of the coating die head 1. Correspondingly, the coating die head 1 installed on the mounting member 31 can also slide out of the frame 2 with the mounting member 31, so that the maintenance personnel do not need to reach into the frame 2 to inspect and repair the coating die head 1.

[0040] It should be noted that the frame 2 is provided with a hole that enables the coating die head 1 to slide out. As mentioned above, the frame 2 is a steel structure frame. When manufacturing the frame 2, it is necessary to reserve a hole that enables the coating die head 1 to slide out when splicing steel parts.

[0041] The side sliding device 3 provided in this embodiment has a coating die head 1 installed on a mounting member 31, and the mounting member 31 slides out of the frame 2 from the side of the frame 2 under the cooperation of the driving mechanism 33 and the sliding mechanism 32. In this way, when the coating die head 1 is inspected and maintained, the coating die head 1 can be located outside the frame 2. Compared with the prior art, maintenance personnel do not need to go deep into the frame 2 to inspect and maintain the die head, which facilitates the operation of maintenance personnel, improves the inspection and maintenance efficiency, and ensures the safety of maintenance personnel.

[0042] The side sliding device 3 provided in the embodiment of the utility model is as follows: Figure 1 and Figure 2 As shown, the sliding mechanism 32 includes a slide rail 321 and a slider 322 matched with the slide rail 321 ; the slider 322 is arranged on the frame 2 , the slide rail 321 is arranged on the mounting member 31 , and the slide rail 321 is slidably connected to the slider 322 .

[0043] In this embodiment, the sliding mechanism 32 includes a slide rail 321 and a slider 322 matched with the slide rail 321, and has a simple structure, is easy to install, and has strong stability. The slider 322 is fixed on the frame 2, and the slide rail 321 is fixed on the mounting member 31. The slide rail 321 is a linear guide rail. The slide rail 321 and the slider 322 are slidably connected by a clamping method, thereby realizing the sliding of the mounting member 31 on the frame 2, so that the mounting member 31 can slide out of the frame 2 from the side of the frame 2.

[0044] It is understandable that in this embodiment, the slider 322 can also be arranged on the mounting member 31, and the slide rail 321 can be arranged on the rack 2, which can also achieve the purpose of sliding the mounting member 31 on the rack 2 through the sliding mechanism 32 in this embodiment.

[0045] It is understandable that, in this embodiment, the sliding mechanism 32 may also be a combination of a sliding groove and a sliding block 322 , which can also achieve the purpose of slidingly installing the mounting member 31 on the frame 2 through the sliding mechanism 32 in this embodiment.

[0046] Optionally, in this embodiment, in order to improve stability, multiple slide rails 321 are provided, all of the slide rails 321 are arranged in parallel, the sliders 322 correspond to the slide rails 321 one by one, and the slide rails 321 are slidably connected to the corresponding sliders 322 .

[0047] For example, in this embodiment, Figure 2 As shown, the sliding mechanism 32 includes two parallel sliding rails 321 , and the two sliding rails 321 are symmetrically arranged about the axis of the screw nut 342 , thereby ensuring the stability of the mounting member 31 .

[0048] Optionally, in this embodiment, in order to ensure the stability of the slide rail 321, a plurality of sliders 322 may be provided corresponding to one slide rail 321, for example, Figure 2 As shown, each slide rail 321 corresponds to two slide blocks 322 .

In addition, the slide rail 321 and the coating die head 1 are respectively mounted on two opposite surfaces of the mounting plate 311, which can avoid interference between the slide rail 321 and the coating die head 1. Since the slide rail 321 is connected to one surface of the mounting plate 311, the connection strength between the slide rail 321 and the mounting plate 311 can be improved, avoiding the problem of connection failure between the slide rail 321 and the mounting plate 311, and improving safety.

[0050] Optionally, in this embodiment, the mounting member 31 can also be a mounting frame, which can be formed by welding or bolting steel pipes, which can also support the coating die head 1 in this embodiment, and achieve the purpose of enabling the coating die head 1 to slide out of the frame 2 from the side of the frame 2 through the cooperation of the slide rail 321 and the slider 322.

When in use, the driving mechanism 33 drives the screw 341 to rotate, and the screw 341 is displaced along its axial direction. Since the screw 341 is rotatably connected to the mounting member 31, the screw 341 will drive the mounting member 31 to displace along its axial direction.

[0055] In this embodiment, since the screw rod 341 will also be displaced along its axial direction when rotating, the driving mechanism 33 also needs to be displaced synchronously with the screw rod 341, so as to ensure the transmission connection relationship between the two, and this can be achieved by arranging the driving mechanism 33 on the mounting member 31. In addition, by arranging the driving mechanism 33 on the mounting member 31, there is no need to arrange other structures for mounting the driving mechanism 33, which can simplify the structure of the side sliding device 3 and facilitate the arrangement of the side sliding device 3.

[0056] Furthermore, by arranging the driving mechanism 33 on the mounting member 31 , the driving mechanism 33 is also transmission-connected with the screw rod 341 , so that the purpose of rotating the screw rod 341 on the mounting member 31 can be achieved.

[0057] In this embodiment, the driving mechanism 33, the screw rod 341 and the slide rail 321 are all located on the same surface of the mounting plate 311. The driving mechanism 33 can also be fixed on the mounting plate 311 by means of bolts or screws.
