Description

Technical Field

[0001] The utility model relates to the technical field of automated production lines, in particular to a semi-automatic restraint and release loading and unloading device and system. Background Art

[0002] With the increasing focus on battery cell safety, the latest battery cell production processes have incorporated restraint and de-restraint processes. This is to prevent cell expansion during charging and discharging, which increases the distance between the positive and negative electrode films, leading to increased internal resistance and ultimately heating and thermal runaway. Semi-automatic equipment demonstrates significant advantages in the compression and decompression of cells, as well as their lifting and lowering within the tray. Traditional semi-automatic compression and decompression devices have shortcomings in applying and releasing pressure on the cells within the tray, ensuring cell stability, and preventing deformation.

[0003] During their research, the inventors discovered that existing technologies primarily rely on manual operation or simple semi-automatic devices, resulting in low efficiency and safety risks. For example, during the process of pressurizing the battery cells, manual operation accuracy is difficult to ensure, which may cause uneven pressure on the battery cells, thereby affecting their performance. In addition, when relieving pressure on the tray, the tediousness and uncertainty of manual operation increase potential risks in the production process. Manual operation is inefficient and labor-intensive during the lifting and lowering of the battery cells, making it difficult to achieve precise synchronization, which affects overall production efficiency.

[0004] However, traditional manual restraint and release methods are complex, inefficient, and difficult to achieve precise control, failing to meet the automated production demands of Industry 4.0. Therefore, there is an urgent need to develop efficient, precise, and highly automated lithium battery restraint and release equipment to meet the needs of new processes and industrial development.

[0034] In an optional embodiment, the tray 100 further includes a pad 130 , which is disposed between the side wall of the tray 100 and the pressure plate 120 .

[0035] like Figure 2 As shown, the tray 100 includes a partition 110, a pressing plate 120 and a pad 130, wherein the partition 110 is used to isolate two adjacent battery cells 500, and protect the surface of the battery cell 500 to prevent the battery cell 500 from being damaged when the battery cell 500 is subjected to pressure.

The second sensor 330 monitors the pressure value applied by the push rod 340 to the tray 100 in real time. When the pressure value reaches the preset pressure value, the pad 130 is manually placed between the mounting plate 320 and the pressure plate 120, thereby completing the restraint of the tray 100.

[0048] Furthermore, a clamping assembly 350 is fixed to one end of the mounting plate 320 away from the first moving assembly 310. The clamping assembly 350 is used to hold the pressing plate 120 and drive the pressing plate 120 to move through the first moving assembly 310.

[0053] Further, the first lifting assembly 410 is actuated, so that the jacking assembly thereof is located above the conveying assembly.

[0079] 3. The control device controls the movement of the first movable component so that its push rod applies pressure to the pressure plate on the pallet. The second sensor sends a pressure signal to the control device in real time. When the applied pressure value reaches the preset pressure value, the control device sends a stop signal to the first movable component. Then, the pad is manually placed between the side wall of the pallet and the pressure plate. Finally, the control device controls the movement of the first movable component so that its push rod moves away from the pallet, and controls the movement of the third movable component so that its limit plate moves away from the pallet, thereby completing the restraint of the battery cell.

[0081] 4. The control device controls the movement of the first movable assembly so that its push rod applies pressure to the pressure plate on the pallet. The second sensor sends a pressure signal to the control device in real time. When the applied pressure reaches a preset pressure value, the control device sends a stop signal to the first movable assembly. Next, the backing plate in the pallet is manually removed. Then, the control device controls the movement of the second movable assembly so that its two clamping parts clamp the pressure plate. Finally, the control device controls the movement of the first movable assembly so that its pressure plate moves away from the battery cell, even if the gap between the partition and the battery cell is increased, thus completing the release of the battery cell.

[0082] 5. The control device controls the movement of the first lifting assembly so that its lifting assembly is located above the conveying assembly. At this time, the battery cells are located on the upper surface of the tray and are removed manually. Then, the control device controls the movement of the second moving assembly so that its two clamping parts release the pressure plate and controls the first moving assembly to reset. Finally, the tray is removed from the conveying assembly manually.
