The mounting base is disposed on the support member, the pressure plate is rotatably connected to the mounting base, and the lifting plate is height-adjustable disposed on the mounting base and rotatably connected to the end of the pressure plate away from the material. The lifting plate can drive the pressure plate to rotate so that the side of the pressure plate away from the lifting plate presses against or releases the material.
[0010] Optionally, it also includes a drive assembly, which includes a drive member and a gripper. The fixed end of the drive member is disposed on the support member, and the gripper is connected to the output end of the drive member. The gripper is connected to the lifting plate, and the output end of the drive member can drive the gripper to move and drive the lifting plate to move up and down.
[0011] Optionally, the gripper includes a mounting portion and a clamping portion, with two clamping portions arranged in parallel.

[0013] Optionally, the mounting base is provided with two parallel mounting plates, and each of the two mounting plates has a sliding hole facing each other. The length direction of the sliding hole forms an angle with the moving direction of the lifting plate.

[0020] The beneficial effects of this utility model are:
[0021] The fixing device provided by this utility model can be used to fix materials (such as battery cells). It is set on a conveying device and can move under the drive of the conveying device, thereby ensuring stable transportation of materials. Specifically, the fixing device includes a support member and a pressure plate assembly.

[0043] The embodiments of this utility model are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0044] This embodiment provides a fixing device, as shown in Figures 1 and 2, which can be used to fix material 100 (such as battery cell). The fixing device is set on the conveying device 10 and can move under the drive of the conveying device 10, thereby ensuring the stable transportation of material 100.
[0045] Specifically, referring to Figures 1, 2, and 4, the fixing device includes a support member 1 and a pressure plate assembly 2. The support member 1 is configured to carry material 100, and it provides initial fixation and support for the material 100. The pressure plate assembly 2 includes a mounting base 21, a pressure plate 22, and a lifting plate 23. The mounting base 21 is disposed on the support member 1, the pressure plate 22 is rotatably connected to the mounting base 21, and the lifting plate 23 is height-adjustably disposed on the mounting base 21 and rotatably connected to the end of the pressure plate 22 away from the material 100. The lifting plate 23 can drive the pressure plate 22 to rotate, so that the side of the pressure plate 22 away from the lifting plate 23 presses against or releases the material 100. In this embodiment, the material 100 may be a lithium-ion battery cell or other items that need to be transferred.
[0046] In other words, by simply controlling the lifting plate 23, the pressure plate 22 can press against or release the material 100. When the pressure plate 22 releases the material 100, the operator can load or unload the material 100; when the pressure plate 22 presses against the material 100, the material 100 can be transferred via the conveying device 10. Due to the pressing action of the pressure plate 22 on the material 100, the pressure plate 22 and the support member 1 together clamp the material 100, further fixing the position of the material 100, effectively preventing the material 100 from sliding relative to each other during transportation and scratching its surface, thus effectively ensuring the stability of transportation.
[0047] Optionally, as shown in Figures 2 and 4, the pressure plate assembly 2 further includes a mating shaft 25, through which the lifting plate 23 is rotatably connected to the pressure plate 22. Specifically, a first through hole is formed in the lifting plate 23, and a second through hole is formed at the end of the pressure plate 22 away from the material 100. The mating shaft 25 passes through the first and second through holes in sequence, thereby realizing the rotatable connection between the lifting plate 23 and the pressure plate 22.
[0048] Continuing, the pressure plate assembly 2 further includes a connecting shaft 24, through which the pressure plate 22 is rotatably connected to the mounting base 21. In one embodiment, a third through hole is formed in the pressure plate 22, the connecting shaft 24 passes through the third through hole, and both ends of the connecting shaft 24 protrude from both sides of the pressure plate 22 and are rotatably connected to the mounting base 21. In another embodiment, the connecting shaft 24 and the pressure plate 22 are integral structures, with the connecting shaft 24 protruding from both sides of the pressure plate 22, and both ends of the connecting shaft 24 rotatably connected to the mounting base 21, both of which enable the rotatable connection between the pressure plate 22 and the mounting base 21.
[0049] Furthermore, the connecting shaft 24 is arranged parallel to the mating shaft 25, with the connecting shaft 24 located on the side of the mating shaft 25 away from the lifting plate 23. That is, the connecting shaft 24 is located in the middle of the pressure plate 22, the pressure plate 22 on one side of the connecting shaft 24 is used to press against the material 100, and the pressure plate 22 on the other side of the connecting shaft 24 is connected to the lifting plate 23 so that it can rotate around the axial direction of the connecting shaft 24 under the drive of the lifting plate 23.
[0050] Referring again to Figure 4, the mounting base 21 has two parallel mounting plates 211, each with a sliding hole 212 facing each other. The length direction of the sliding hole 212 forms an angle with the moving direction of the lifting plate 23. The two ends of the connecting shaft 24 are rotatably connected to the two sliding holes 212 and can slide along the length direction of the sliding holes 212. With this configuration, when the lifting plate 23 moves downward, it causes the end of the pressure plate 22 away from the material 100 to rotate downward. Simultaneously, the pressure plate 22 can also move away from the material 100 along the sliding hole 212, allowing the other end of the pressure plate 22 to rotate and open while simultaneously moving away from the material 100. This facilitates the operator in placing the material 100 on the support 1, effectively preventing collisions between the pressure plate 22 and the material 100. In this embodiment, the length direction of the sliding hole 212 is perpendicular to the moving direction of the lifting plate 23. Of course, in other embodiments, the height of the sliding hole 212 gradually decreases along the direction close to the lifting plate 23, which can also achieve the above-mentioned beneficial effects.
[0051] Optionally, the pressure plate assembly 2 also includes rolling bearings 28. Two rolling bearings 28 are provided, each located at one end of the connecting shaft 24 and rotatably mounted within a corresponding sliding hole 212. The rolling bearings 28 ensure smooth movement of the connecting shaft 24 along the sliding hole 212 and effectively reduce friction, thus minimizing energy loss such as heat generation.
[0052] Alternatively, as shown in Figure 4, a protective layer 27 is provided on the side of the pressure plate 22 facing the material 100. This protective layer 27 is a urethane layer. Urethane has the characteristics of buffering, noise reduction, shock absorption, wear resistance, and high temperature resistance. It can increase the friction and protect the outer surface of the material 100 when in contact with the material 100.
[0053] Referring again to Figures 2-4, the fixing device further includes a drive assembly 3, which includes a drive member 31 and a gripper 32. The fixed end of the drive member 31 is disposed on the support member 1, and the gripper 32 is connected to the output end of the drive member 31 and is connected to the lifting plate 23. The output end of the drive member 31 can drive the gripper 32 to move, thereby causing the lifting plate 23 to move up and down, and in turn causing the pressure plate 22 to rotate. Exemplarily, in this embodiment, the drive member 31 is a slide cylinder, which is fixed to the side of the support member 1. The telescopic part of the slide cylinder moves up and down, and the gripper 32 is disposed at the top of the telescopic part of the slide cylinder so as to move up and down under the drive of the telescopic part of the slide cylinder. Of course, in other embodiments, the drive member 31 can also be other structures that can drive the gripper 32 to move up and down, such as an electric push rod, etc. The specific choice can be made according to the actual situation, and there is no limitation here.
[0054] Specifically, as shown in Figure 3, the gripper 32 includes a mounting portion 321 and a clamping portion 322. The two clamping portions 322 are arranged in parallel, and the mounting portion 321 is connected between the two clamping portions 322 to form a clamping space. The mounting portion 321 is located at the output end of the drive member 31, and the lifting plate 23 is inserted into the clamping space. That is, the upper and lower end faces of the lifting plate 23 abut against the opposite side surfaces of the two clamping portions 322, respectively. When the output end of the drive member 31 drives the gripper 32 to move up and down, the lifting plate 23 can be driven to move up and down through the two clamping portions 322.
[0055] Furthermore, in order to make the movement of the lifting plate 23 more stable and reliable, as shown in Figure 3, the pressure plate assembly 2 also includes a guide member 26, which is used to guide the up and down movement of the lifting plate 23.
[0056] Specifically, the guide member 26 is disposed on the mounting base 21, and the lifting plate 23 is connected to the guide member 26. In this embodiment, the guide member 26 includes a guide rod and a linear bearing. The guide rod is fixed on the mounting base 21 and extends vertically. The linear bearing is sleeved on the guide rod and can move up and down along the guide rod. The lifting plate 23 is connected to the linear bearing, which improves the smoothness of the lifting plate 23's up and down movement.
[0057] As shown in Figures 1 and 2, this embodiment also provides a conveying mechanism, which includes a conveying device 10, a driving device 20, and the aforementioned fixing device. The conveying device 10 includes a conveyor belt 101, a support member 1 disposed on the conveyor belt 101, and a driving device 20 connected to the conveyor belt 101. The driving device 20 can drive the conveyor belt 101 to rotate, thereby moving the support member 1 and the material 100 on the conveyor belt 101 to complete the transportation of the material 100. Exemplarily, the driving device 20 can be a servo motor.
[0058] Optionally, referring to Figures 1 and 2, the conveying device 10 further includes support rails 102, with two support rails 102 arranged parallel and spaced apart on both sides of the conveyor belt 101. The fixing device also includes multiple rollers 4, which are arranged on both sides of the support member 1 along a conveying direction perpendicular to the conveyor belt 101, with the axis of the rollers 4 perpendicular to the conveying direction. When the conveyor belt 101 moves the support member 1, the rollers 4 rotatably abut against the support rails 102. That is, the rollers 4 provide stable support for the support member 1 when it moves, thereby ensuring the smoothness of the material 100 during transportation.
[0059] The conveying process of the conveying mechanism provided in this embodiment is as follows (taking the conveyed material 100 as an example of a battery cell):
[0060] 1. When the conveying mechanism is working, the drive unit 20 is started first, and the conveyor belt 101 begins to rotate under the action of the drive unit 20. The left side of the conveying mechanism (left side in Figure 1) is the feeding end of the conveyor line, and the right side (right side in Figure 1) is the feeding end of the conveyor line. A fixing device is fixed on the conveyor belt 101, and the battery cell is placed on the fixing device. The support member 1 of the fixing device consists of three support plates, and four rollers 4 are set under each support plate to form a loading trolley. The three loading trolleys support one battery cell. When the conveyor belt 101 starts to rotate, the loading trolley begins to move to the right.
[0061] 2. As the conveyor belt 101 begins to move, the drive component 31 on the side of the support member 1 controls the gripper 32 to move downwards. When the gripper 32 moves downwards, it presses down the lifting plate 23 of the pressure plate assembly 2. Since the lifting plate 23 is fixed on a linear bearing that can move linearly, as the lifting plate 23 moves downwards, the rolling bearing 28 and the mating shaft 25 move relative to each other. The rolling bearing 28 rolls away from the battery cell in the sliding hole 212 of the mounting plate 211. Under the action of the prying force, the pressure plate 22 tilts upwards with the connecting shaft 24 as the center, that is, the pressure plate 22 is opened. At this time, the external robot can place the battery cell on the loading trolley.
[0062] 3. After the battery cell is placed, the drive unit 31 drives the gripper 32 to move upward, thereby raising the lifting plate 23. The rolling bearing 28 rolls in the sliding hole 212 of the mounting plate 211 towards the battery cell. Under the action of relative force, the pressure plate 22 rotates around the connecting shaft 24. The side of the pressure plate 22 away from the lifting plate 23 rotates down and presses against the surface of the battery cell to press the battery cell tightly.
[0063] 4. When the fixing device moves to the unloading end on the right side of the conveyor belt 101, the drive unit 31 repeats the movement in step 2 to lift the pressure plate 22 so that the external robot can unload the battery cell.
[0064] 5. After each device completes its operation, it should return to its initial state.
[0065] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
