To this end, this invention proposes an electrode coating device with a detachable die head, which can detach the coating die head from the coating station, enabling maintenance and cleaning of the coating die head outside the coating station, thus improving the convenience of maintenance and cleaning of the coating die head.

[0006] This utility model also proposes a coating machine with a detachable electrode coating device as described above.

[0007] A detachable electrode coating device according to a first aspect embodiment of the present invention includes: The die head assembly is equipped with a coating die head; The first connecting plate is used to position the die head assembly at the coating station; The second connecting plate is detachably connected to the first connecting plate; The die head assembly is slidably connected to the first connecting plate and the second connecting plate, and the die head assembly slides from the first connecting plate to the second connecting plate so that the first connecting plate can drive the disassembly of the coating die head.

[0008] The detachable electrode coating device according to the embodiments of the present invention has at least the following beneficial effects: This invention, by providing a detachably connected first and second connecting plate, and a die head seat assembly slidably connected to the first and second connecting plates, allows the die head seat assembly to be slid from the first connecting plate to the second connecting plate when maintenance and cleaning of the coating die head are required. The second connecting plate is then removed from the first connecting plate, thereby causing the first connecting plate to simultaneously disassemble the coating die head, allowing it to detach from the coating station. This enables maintenance and cleaning of the coating die head outside the coating station, improving the convenience of coating die head maintenance and cleaning.

[0009] According to some embodiments of the present invention, the first connecting plate has a horizontally arranged first slide rail, and the second connecting plate has a horizontally arranged second slide rail. The first slide rail and the second slide rail are respectively used to guide the sliding of the mold head assembly on the first connecting plate and the second connecting plate.

[0010] The advantages of this invention are: by setting a first slide rail on the first connecting plate to guide the sliding of the mold head assembly, and setting a second slide rail on the second connecting plate to guide the sliding of the mold head assembly, the sliding of the mold head assembly on the first connecting plate and the second connecting plate is ensured to be stable and accurate. At the same time, it ensures smooth transfer of the mold head assembly between the first connecting plate and the second connecting plate, prevents the mold head assembly from shifting or getting stuck during the transfer between the first connecting plate and the second connecting plate, and improves the accuracy and reliability of the disassembly and installation of the mold head assembly.

[0011] According to some embodiments of the present invention, one of the first connecting plate and the second connecting plate is provided with a pin, and the other of the first connecting plate and the second connecting plate is provided with a socket.

Thus, when the first connecting plate adjusts its vertical position on the third slide rail, the first drive module drives the first connecting plate to slide up and down, thereby automating the vertical position adjustment of the coating die head, reducing manual operation, and improving adjustment efficiency and accuracy. In addition, the first drive module can be integrated with a control system to achieve rapid response to changes in production parameters, such as fluctuations in electrode thickness, thereby improving coating quality and production efficiency. When the second connecting plate adjusts its vertical position on the third slide rail, the first drive module drives the second connecting plate to slide up and down, thereby automating the vertical position adjustment of the second connecting plate, reducing manual operation, and improving adjustment efficiency and accuracy.

It can be understood that when the mobile frame 250 needs to be moved, the lifting feet can be moved upward so that the lifting feet are off the ground and the casters are in contact with the ground, thereby avoiding interference between the lifting feet and the ground when the mobile frame 250 moves; when the mobile frame 250 does not need to be moved, the lifting feet can be moved downward so that the lifting feet are in contact with the ground and the entire mobile frame 250 is lifted upward so that the casters are off the ground, thereby avoiding contact between the casters and the ground and causing the mobile frame 250 to easily shift.

[0076] Furthermore, the lifting outriggers can be equipped with threaded rods that are threadedly connected to the movable frame 250. By rotating the threaded rods, the height of the lifting outriggers can be adjusted.

[0077] The coating machine according to a second aspect of this utility model includes an electrode coating device with a detachable die head as described in any of the above embodiments. The coating machine includes the electrode coating device with a detachable die head as described in the first aspect. The electrode coating device includes a die head seat assembly 100, a first connecting plate 120, and a second connecting plate 130. The die head seat assembly 100 is equipped with a coating die head 110, with the extrusion port of the coating die head 110 facing downwards. The first connecting plate 120 is used to position the die head seat assembly 100 at the coating station. The second connecting plate 130 is detachably connected to the first connecting plate 120. The die head seat assembly 100 is slidably connected to the first connecting plate 120 and the second connecting plate 130. The die head seat assembly 100 slides from the first connecting plate 120 to the second connecting plate 130 so that the first connecting plate 120 drives the detachment of the coating die head 110.

[0078] It is understandable that this embodiment can adapt to the coating process of double-sided coating of electrode sheets by facing the extrusion port of the coating die 110 downward. Considering that the extrusion port of the coating die 110 faces downward, it is necessary to maintain and clean the extrusion port from the bottom of the coating die 110, which is difficult to operate. In addition, there are other structures blocking the bottom of the coating die 110 at the coating station, making it difficult for operators to maintain and clean the coating die 110 from the bottom at the coating station. To address the difficulty of maintaining and cleaning the coating die 110 due to its downward-facing extrusion port at the coating station, this embodiment provides a detachably connected first connecting plate 120 and second connecting plate 130, as well as a die holder assembly 100 slidably connected to the first connecting plate 120 and second connecting plate 130, in the electrode coating apparatus. When maintenance and cleaning of the coating die 110 are required, the die holder assembly 100 can be slid from the first connecting plate 120 to the second connecting plate 130, and then the second connecting plate 130 can be removed from the first connecting plate 120. This allows the first connecting plate 120 to simultaneously disassemble the coating die 110, enabling it to detach from the coating station and allowing maintenance and cleaning of the coating die 110 outside the coating station, thus improving the convenience of maintenance and cleaning of the coating die 110.
