[0032] As shown in FIG. 1 , FIG. 2 and FIG. 3 , in one embodiment, a loading and unloading machine 10 is provided, comprising a loading and unloading structure 100 and a transport mechanism 200.

When the battery cell processing equipment needs to be loaded, the conveying mechanism 200 conveys the battery cell material box 21 on the first pallet 22 in the loading area 110 to the target area (i.e., the loading station area of ​​the battery cell processing equipment), realizes automatic loading of the battery cell processing equipment, and improves the stability and processing efficiency of battery cell loading. When all the batteries in the battery cell material box 21 in the target area are loaded, the battery cell material box 21 becomes an empty material box 23, and the conveying mechanism 200 conveys the empty material box 23 in the target area to the second pallet 24 in the unloading area 120. Repeat the above actions until all the cell boxes 21 on the first pallet 22 of the loading area 110 are loaded, and the operator uses the pallet conveying mechanism to drag away the first pallet 22 of the loading area 110, and re-feed another first pallet 22 carrying full cell boxes 21 to the loading area 110. Similarly, when the second pallet 24 of the unloading area 120 carries full and empty boxes 23, the operator uses the pallet conveying mechanism to drag away the second pallet 24 of the unloading area 120, and re-feed another empty second pallet 24 to the unloading area 120. The loading and unloading machine 10 in the present application can realize automatic loading and unloading without stopping, is simple and convenient to operate, has a high degree of automation, reduces the labor intensity and operational safety risks of operators, reduces labor costs, and improves the processing efficiency of battery packs.

[0060] In order to further understand the working principle of the loading and unloading machine 10, one working process of the loading and unloading machine 10 will be described in detail below by taking one of the working processes of the loading and unloading machine 10 as an example.

[0061] 1. The operator controls the entire loading and unloading machine 10 to start through the control panel on the fence 300.

[0062] 2. The operator uses the pallet conveying mechanism to deliver the unloaded second pallet 24 to the unloading area 120, and then uses the pallet conveying mechanism to deliver the first pallet 22 stacked with battery cell boxes 21 to the loading area 110. The first in-place detection member 130 senses that the first pallet 22 is in place and feeds back the in-place signal to the operation panel, and the operation panel controls the operation of the robotic arm 220.

[0063] 3. The robot arm 220 moves to the loading area 110, and first uses the second position detection member 235 on the first clamp 233 and the second clamp 234 to detect whether there is a battery cell box 21 in the clamping space; when it is determined that there is a battery cell box 21 in the clamping space, the third position detection member 236 is used to locate the specific position of the battery cell box 21 in the clamping space. After the positioning is completed, the control panel controls the movement of the slider on the cylinder drive guide rail 237 according to the detection result of the third position detection member 236, thereby controlling the first clamp 233 and the second clamp 234 to move in a direction close to each other to clamp the battery cell box 21; after the clamping is completed, the battery cell box 21 is sent to the loading station area of ​​the battery cell processing equipment to complete the automatic loading.

[0064] 4. After the battery cell box 21 is loaded in the loading station area, it becomes an empty box 23. The robot arm 220 moves to the loading station area, and the cylinder drives the slider on the guide rail 237 to move, thereby controlling the first clamp 233 and the second clamp 234 to move in a direction close to each other to clamp the empty box 23, and send the empty box 23 to the second pallet 24 of the unloading area 120.

[0065] 5. Repeat the above actions until all the battery cell boxes 21 on the first pallet 22 of the loading area 110 are loaded, and all the empty boxes 23 are transported to the second pallet 24 of the unloading area 120; the operator uses the pallet conveying mechanism to drag away the first pallet 22 of the loading area 110, and re-input another first pallet 22 stacked with battery cell boxes 21 to the loading area 110; the operator uses the pallet conveying mechanism to drag away the second pallet 24 loaded with full and empty boxes 23 in the unloading area 120, and re-input another unloaded second pallet 24 to the unloading area 120, thereby realizing fully automatic loading of battery cells.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0069] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0070] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0071] It should also be understood that when explaining the connection relationship or positional relationship of elements, although not explicitly described, the connection relationship and positional relationship are interpreted as including an error range, which should be within the acceptable deviation range of a specific value determined by those skilled in the art. For example, "approximately", "approximately" or "substantially" may mean within one or more standard deviations, which are not limited here.

[0072] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
