Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a die head adjustment mechanism and a coating machine. Background Technology

[0002] Wet coating is one of the main production processes for lithium-ion batteries. Typically, wet coating equipment includes a coating die and a coating roller. The coating die sprays an active material slurry onto a foil material on the coating roller. As the coating roller rotates, the slurry is applied to different positions on the foil. The coated foil is then conveyed to an oven via the roller and downstream mechanisms. After drying, the battery electrode is obtained. In existing technologies, the foil is usually transported via rollers. Differences in the transport speed and tension between the various transport rollers or pressure rollers can cause a shift in the transport direction of the foil, leading to a shift in the position of the slurry coating on the foil.

[0003] To avoid this problem, the position of the coating machine's die head needs to be adjusted to ensure precise application of the slurry onto the foil. For example, the coating die head disclosed in patent 202322807287.6 uses a horizontal moving mechanism to drive the die head body to move along the width of the electrode sheet; the direction of movement of the die head body is also its length. The coating machine is relatively large in this direction, and adding a horizontal moving mechanism along the length of the die head body would further increase the installation space required, leading to more stringent requirements for the coating machine's installation and operation, making it difficult to meet various production conditions.

[0004] Therefore, there is an urgent need for a die head adjustment mechanism and a coating machine to solve the above problems. Utility Model Content

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] like Figures 1 to 2 As shown, this embodiment provides a die head adjustment mechanism for driving the die head 100 of a coating machine to move along the length direction of the die head 100, which is also the first direction in this embodiment. The die head adjustment mechanism includes a drive assembly 1, a transmission assembly 2, and a guide assembly 3. The drive assembly 1 is located on one side of the die head 100 in a second direction, which is perpendicular to the first direction. The transmission assembly 2 includes a drive connector 21, a slider 22, and a die head mounting component 23. The drive connector 21 is connected to the slider 22 and the output end of the drive assembly 1, respectively. The die head mounting component 23 is disposed on the slider 22 and is used to mount the die head 100. The guide assembly 3 includes a base plate 31 and a guide rail 32. The guide rail 32 extends along the first direction and is disposed on the base plate 31. The slider 22 is slidably connected to the guide rail 32.

[0041] In specific implementation, the output end of the drive assembly 1 drives the drive connector 21 to move. Since the slider 22 is also connected to the drive connector 21, and the slider 22 will move along the first direction, the slider 22 is connected to one side of the drive connector 21 in the second direction. The slider 22 and the drive connector 21 are arranged sequentially in the second direction. The overall structure of the drive connector 21 is L-shaped. The drive connector 21 has a first end extending in the third direction and a second end extending in the second direction. The first end is connected to the output end of the drive assembly 1, while the second end extends to the slider 22. The slider 22 is connected to the die head mounting component 23 and the die head 100. By adding the drive connector 21, the drive assembly 1 can still drive the die head 100 to move in the first direction when it is on one side of the die head 100 in the second direction, thereby reducing the size of the coating machine in the length direction of the die head 100. This die head adjustment mechanism can solve the problem of the large installation space occupied by the adjustment mechanism in the prior art, so as to meet various production conditions.

[0042] like Figure 1 and Figure 2 As shown in this embodiment, the third direction is the vertical direction, and the first direction and the second direction are both horizontal directions. Among them, oa is the first direction, ob is the second direction, and oc is the third direction. The first direction, the second direction, and the third direction are all perpendicular to each other.

[0043] Optionally, the drive assembly 1 includes a motor 11 and a lead screw 12. The lead screw 12 is coaxially connected to the output shaft of the motor 11, extends along a first direction, and is threadedly connected to the drive connector 21. The drive connector 21 has an L-shaped overall structure, with a first end extending in a third direction and a second end extending in a second direction. The first end has a threaded hole, and the lead screw 12 passes through the threaded hole of the drive connector 21. In a specific implementation, the output shaft of the motor 11 rotates to drive the lead screw 12 to rotate around the first direction. The connection between the drive connector 21 and the slider 22 ensures that the movement trajectories of the drive connector 21 and the slider 22 are consistent, that is, both are limited by the extension direction of the guide rail 32 and can only move in the first direction. This allows the drive connector 21 to move along the extension direction of the lead screw 12 when the lead screw 12 rotates.

[0044] In this embodiment, the motor 11 is a servo motor. The servo motor can rotate forward or backward by a preset angle as needed, thereby adjusting the rotation direction and rotation angle of the lead screw 12, and thus adjusting the moving direction and moving distance of the drive connector 21 in the first direction.

[0045] Optionally, the die head adjustment mechanism further includes a detection component 4, which is signal-connected to the motor 11. The detection component 4 is used to detect the moving distance of the drive connector 21. In specific implementations, the detection component 4 can be a radar rangefinder. The detection component 4 is set on either the die head 100 or the transmission component 2. By measuring the distance between it and a fixed position on the coating machine, the moving distance and direction of the die head 100 can be determined, and the motor 11 can be controlled based on the detection results.

[0046] Optionally, the detection component 4 is a photoelectric switch. The detection component 4 includes a transmitter 42 and a receiver 41. One of the transmitter 42 or receiver 41 is disposed on the guide component 3, and the other of the transmitter 42 or receiver 41 is disposed on the drive connector 21. In this embodiment, the transmitter 42 is disposed on the guide component 3, and the receiver 41 is disposed on the drive connector 21. Two receivers 41 are disposed at intervals in the first direction. The receivers 41 move with the drive connector 21. When either receiver 41 receives the light signal from the transmitter 42, it indicates that the mold head 100 has moved into position. At this time, the detection component 4 feeds back a stop signal to the motor 11 so that the mold head 100 stops moving.

[0047] Optionally, the transmitter 42 may have multiple fixed positions in the first direction, and can be fixed at any position according to the required moving distance of the mold head 100. The receiver 41 may also have multiple fixed positions in the first direction, and can be fixed at any position according to the required moving distance of the mold head 100. The fixed positions of both receivers 41 are adjustable.

[0048] Optionally, such as Figure 2 As shown, the guide assembly 3 also includes a support base 33, which includes a top plate 332 extending along a first direction and two side plates 331 arranged opposite to each other in the first direction and connected to the two ends of the top plate 332. The two side plates 331 have mounting holes arranged opposite to each other. The two ends of the lead screw 12 rotatably pass through the mounting holes on both sides, while the drive connector 21 is sleeved on the lead screw 12 and located between the two side plates 331. The support base 33 provides support for the lead screw 12 in a third direction, while keeping the position of the drive connector 21 unchanged in the third direction. In a specific implementation, bearings are installed in the mounting holes, and both ends of the lead screw 12 pass through the inner rings of the bearings, thereby ensuring that the lead screw 12 can rotate relative to the support base 33. In this embodiment, the transmitter 42 is fixed to the top plate 332 of the support base 33.

[0049] Optionally, such as Figure 2As shown, the motor 11 includes a motor body and an output shaft. The motor body is mounted on the base plate 31. The guide assembly 3 also includes a connecting seat 34. The motor body, the connecting seat 34, and the support seat 33 are connected in sequence in the first direction. The connecting seat 34 has an inner cavity, and the two ends of the connecting seat 34 are through. The coupling 13 is disposed in the inner cavity. The output shaft of the motor 11 passes through one side of the connecting seat 34 and extends into the inner cavity to be coaxially connected with the coupling 13. The lead screw 12 passes through the other side of the support seat 33 and the connecting seat 34 and is also coaxially connected with the coupling 13.

[0050] Furthermore, multiple sliders 22 are configured, all of which are slidably mounted on the guide rail 32. One slider 22 is connected to both the drive connector 21 and the die head mounting component 23, while the other sliders 22 are only connected to the die head mounting component 23. By using only one slider 22 connected to the drive connector 21, the other sliders 22 can move accordingly when the die head mounting component 23 is driven. This reduces the assembly complexity of the transmission assembly 2 while providing support for the die head mounting component 23 with multiple sliders 22. In this embodiment, the multiple sliders 22 are spaced apart in the first direction.

[0051] Furthermore, the mold head mounting component 23 includes a mounting plate 231 and a base 232. The mounting plate 231 is disposed above the base 232, and the mold head 100 is disposed above the mounting plate 231. At least one of the mounting plate 231 and the base 232 is fixedly connected to the slider 22. The mounting plate 231 extends along a first direction, and its length is greater than that of the mold head 100, providing sufficient support surface for the installation of the mold head 100. The base 232 is disposed below the mounting plate 231. The base 232 supports the mounting plate 231, prevents the weight of the mold head 100 from being transmitted to the slider 22, and presses the slider 22 against the guide rail 32 to obstruct the movement of the slider 22 on the guide rail 32.

[0052] Optionally, the base support 232 includes two sets arranged opposite to each other along the first direction, with the two sets of base supports 232 spaced apart, and the guide rail 32 located between the two sets of base supports 232. The base supports 232 are used to provide support at both ends of the mounting plate 231 along its length, so as to ensure that the mounting plate 231 can always remain horizontal when moving in the first direction.

[0053] Optionally, the drive connector 21 and the slider 22 are detachably connected. The slider 22 and the die head mounting component 23 are detachably connected. The die head mounting component 23 and the die head 100 are detachably connected. Detachable connections facilitate the replacement or maintenance of the transmission assembly 2 and the drive assembly 1. The detachable connection can be achieved by using a fastening bolt and an internally threaded hole. For example, if the drive connector 21 and the slider 22 are detachably connected, a through hole can be provided on the drive connector 21, and an internally threaded hole can be provided on the slider 22. One end of the fastening bolt can be passed through the through hole and threaded into the internally threaded hole.

[0054] This embodiment also provides a coating machine, including a die head 100 and the aforementioned die head adjustment mechanism. The drive component 1 of the die head adjustment mechanism is connected to one side of the die head 100 in a second direction, and the drive component 1 is used to drive the die head 100 to move in a first direction. The drive component 1 of the die head adjustment mechanism of this coating machine is arranged perpendicular to the moving direction of the die head 100, which can effectively reduce the size of the coating machine in the length direction of the die head 100, thereby solving the problem that the adjustment mechanism in the prior art causes the coating machine to occupy a large installation space, so as to meet various production conditions.

[0055] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
