The fixture falls on the lifting plate due to gravity and is not directly fixed. The area of ​​the lifting plate is much smaller than the bottom plate of the fixture, and there is a risk of the bottom plate of the fixture hanging in the air, causing it to tilt and overturn.

[0026] Figure 1 , is a schematic diagram of the structure of a workpiece shifting device in one embodiment.

[0027] In this embodiment, if Figure 1 As shown, the workpiece shifting device is used to lift the battery cell to the top cover pre-processing fixture to remove the battery cell after the top cover pre-welding is completed. The workpiece shifting device includes a clamping mechanism 10 and a lifting mechanism 20.

[0028] like Figure 2 As shown, the clamping mechanism 10 includes a clamping assembly 120 and a supporting and limiting assembly 140. The clamping assembly 120 is disposed on the supporting and limiting assembly 140, and the clamping assembly 120 can clamp a workpiece.

[0029] The clamping mechanism 10 may be a functional structure that is arranged between the top cover pre-processing fixture and the lifting mechanism 20 in the vertical direction, and can clamp the battery cell after the top cover pre-processing fixture is released and is clamped to the lifting mechanism 20. The clamping assembly 120 may be a functional component that is arranged below the top cover pre-processing fixture in the vertical direction, and can clamp the battery cell after the top cover pre-processing fixture is released. The supporting and limiting assembly 140 may be a functional component that is arranged above the lifting mechanism 20 in the vertical direction, and can carry the clamping assembly 120 and is clamped to the lifting mechanism 20.

[0030] The lifting mechanism 20 can be engaged with the supporting and limiting assembly 140 .

[0031] The lifting mechanism 20 can be a functional structure arranged below the clamping mechanism 10 in the vertical direction, and can be close to and clamped to the side of the supporting and limiting component 140 in the clamping mechanism 10 away from the clamping component 120 or clamped to the middle of the supporting and limiting component 140.

[0032] Optionally, the lifting mechanism 20 includes a lifting limit assembly 220 and a lifting drive assembly 240, the supporting limit assembly 140 includes a clamping supporting member 1420 and a transverse locking member 1440, the transverse locking member 1440 is arranged on a side of the clamping supporting member 1420 close to the lifting limit assembly 220, and the lifting drive assembly 240 can drive the lifting limit assembly 220 to approach and clamp on the transverse locking member 1440.

[0033] The lifting limit assembly 220 may be a functional assembly that is arranged opposite to the supporting limit assembly 140 in the clamping mechanism 10 and can be close to and clamped to the supporting limit assembly 140. The lifting drive assembly 240 may be a functional assembly that is arranged in the vertical direction in the direction of the lifting limit assembly 220 and can drive the lifting limit assembly 220 to lift or lower. The clamping support 1420 may be a support member that is arranged opposite to the lifting limit assembly 220 and can carry the clamping assembly. The transverse clamping member 1440 may be a transverse limit member that is arranged opposite to the lifting limit assembly 220 and can be clamped to the lifting limit assembly 220.

[0034] The lifting limit assembly 220 includes a lifting bearing member 2220 , and the lifting bearing member 2220 is provided with a transverse offset limit hole. The transverse clamping member 1440 can extend into and be clamped in the transverse offset limit hole under the action of the lifting drive assembly 240 .

[0035] The lifting bearing member 2220 may be a bearing member arranged opposite to the clamping bearing member 1420 in the supporting and limiting assembly 140, and may be close to and abut against the clamping bearing member 1420. The lateral offset limiting hole may be a lateral limiting hole arranged in the middle of the lifting bearing member 2220, and may be accommodated and clamped to the lateral clamping member 1440.

[0036] Optionally, the transverse retaining member 1440 and the transverse offset limiting hole are arranged in parallel, the geometric center line of the lifting supporting member 2220 is parallel to the geometric center line of the clamping supporting member 1420, the size of the lifting supporting member 2220 is smaller than the size of the clamping supporting member 1420, and the size of the transverse retaining member 1440 is smaller than the size of the transverse offset limiting hole. By constraining the relative positions of the lifting supporting member 2220 and the clamping supporting member 1420 and the relative sizes of the transverse retaining member 1440 and the transverse offset limiting hole, the matching stability of the lifting supporting member 2220 and the clamping supporting member 1420 can be improved while ensuring that the transverse retaining member 1440 can smoothly extend into the transverse offset limiting hole.

[0037] It should be noted that when the lifting support member 2220 is in contact with the clamping support member 1420, the two side surfaces of the transverse clamping member 1440 are directly opposite to the inner wall of the transverse offset limiting hole, that is, there is a gap between the two side surfaces of the transverse clamping member 1440 and the inner wall of the transverse offset limiting hole; when the clamping support member 1420 shakes, the two side surfaces of the transverse clamping member 1440 can be clamped to the inner wall of the transverse offset limiting hole; for example, when the clamping support member 1420 drives the transverse clamping member 1440 to shake to the left relative to the transverse offset limiting hole, at this time The left side surface of the transverse locking member 1440 moves toward the inner wall of the transverse offset limiting hole, and the gap between the two gradually disappears until the transverse locking member 1440 is engaged with the inner wall of the transverse offset limiting hole, providing support and restraint for the transverse locking member 1440 and the clamping supporting member 1420, and effectively improving the lateral shaking amplitude of the clamping supporting member 1420 and the transverse locking member 1440, thereby improving the matching stability of the jacking supporting member 2220 and the clamping supporting member 1420, and further ensuring the matching stability of the clamping mechanism 10 and the jacking mechanism 20.

[0038] Optionally, there are multiple transverse clamping members 1440, and any transverse clamping members 1440 are spaced apart and distributed on both sides of the clamping supporting member 1420, and any transverse clamping members 1440 are arranged in parallel; any transverse clamping member 1440 can be a convex chamfered bracket, and when the clamping supporting member 1420 shakes, one side of the convex chamfered bracket is chamfered close to and clamps one side inner wall of the transverse offset limiting hole, and the other side of the convex chamfered bracket is chamfered away from the opposite side inner wall of any transverse offset limiting hole; by increasing the number of transverse clamping members 1440 and limiting the shape of the transverse clamping members 1440, it is possible to further improve the stability of the clamping action between the transverse clamping members 1440 and the transverse offset limiting holes while improving the degree of smoothness with which the transverse clamping members 1440 extend into the transverse offset limiting holes.

[0039] The supporting limit assembly 140 also includes a vertical clamping limit member 1460, which is arranged in a direction perpendicular to the clamping supporting member 1420. The lifting limit assembly 220 also includes a vertical lifting limit member 2240, which is arranged in a direction perpendicular to the lifting supporting member 2220. The vertical lifting limit member 2240 is arranged around the lateral offset limiting hole, and the vertical lifting limit member 2240 can be plugged into the vertical clamping limit member 1460 under the action of the lifting drive assembly 240.

[0040] The vertical clamping limiter 1460 can be a vertical limiter vertically arranged on the clamping support 1420 and can be plugged into the vertical lifting limiter 2240 in the lifting limiter assembly 220. The vertical lifting limiter 2240 can be a vertical limiter vertically arranged on the lifting support 2220 and can be close to and plugged into the vertical clamping limiter 1460.

[0041] It should be noted that, when the lifting supporting member 2220 abuts against the clamping supporting member 1420, the vertical lifting limit member 2240 on the lifting supporting member 2220 approaches and is inserted into the vertical clamping limit member 1460 in the clamping supporting member 1420. When the clamping supporting member 1420 drives the vertical clamping limit member 1460 to shake, due to the plug-in matching relationship between the vertical lifting limit member 2240 and the vertical clamping limit member 1460, the vertical lifting limit member 2240 provides support and restraint for the vertical clamping limit member 1460 in the vertical direction, which can effectively reduce the vertical shaking amplitude of the vertical clamping limit member 1460 relative to the vertical lifting limit member 2240 in the vertical direction, and can improve the matching stability of the lifting supporting member 2220 and the clamping supporting member 1420, thereby ensuring the matching stability of the clamping mechanism 10 and the lifting mechanism 20.

[0042] Optionally, the gap value between the vertical clamping limit member 1460 and the vertical jacking limit member 2240 is greater than the gap value between the transverse clamping member 1440 and the inner wall of the transverse offset limit hole; by limiting the gap value between the vertical clamping limit member 1460 and the vertical jacking limit member 2240, and the gap value between the transverse clamping member 1440 and the inner wall of the transverse offset limit hole, the problem of excess vibration of the transverse clamping member 1440 due to collision with the jacking support member 2220 during the process of the jacking support member 2220 approaching and abutting against the clamping support member 1420 can be improved, and the matching stability of the jacking support member 2220 and the clamping support member 1420 can be further improved.

[0043] Optionally, the vertical clamping limiter 1460 may be a pin sleeve, and the vertical lifting limiter 2240 may be a pin.

[0044] When the battery cell after the top cover welding is completed is taken out, the jacking drive component 240 (such as an electric cylinder) in the jacking mechanism 20 drives the jacking receiving member 2220 (such as a jacking receiving plate) in the jacking limit component 220 to move in the vertical direction toward the supporting limit component 140 in the clamping mechanism 10. First, the vertical jacking limit member 2240 (such as a pin) arranged on the jacking receiving member 2220 (such as a jacking receiving plate) approaches and is inserted into the vertical clamping limit member 1460 (such as a pin sleeve) on the clamping support member 1420 (such as a jacking fixture bottom plate) in the supporting limit component 140. (such as a pin) provides support and restraint for the vertical clamping limit member 1460 (such as a pin sleeve) in the vertical direction, thereby restraining the relative position relationship between the jacking supporting member 2220 (such as a jacking supporting plate) and the clamping supporting member 1420 (such as a jacking fixture bottom plate) in the vertical direction. The vertical jacking limit member 2240 (such as a pin) and the vertical auxiliary limit member (such as a pin sleeve) are both conical structures and there is a gap between the two. In addition, the jacking supporting member 2220 (such as a jacking supporting plate) and the supporting member (such as a clamping supporting bottom plate) have different areas, resulting in the risk of excess shaking of the supporting member (such as the clamping supporting bottom plate) due to more suspension after the jacking is in place.

[0045] At the same time, the lateral offset limiting hole arranged in the middle of the lifting supporting member 2220 (such as the lifting supporting plate) is close to and extends into the lateral clamping member 1440 in the middle of the clamping supporting member 1420 (such as the lifting clamp bottom plate), until the two side surfaces of the lateral clamping member 1440 are completely opposite to the inner wall of the lateral offset limiting hole, that is, there is a gap between the two side surfaces of the lateral clamping member 1440 and the inner wall of the lateral offset limiting hole. If the clamping supporting member 1420 shakes, one side of the lateral clamping member 1440 moves toward the inner wall of the lateral offset limiting hole, and the gap between the two gradually disappears until the lateral clamping member 1440 is clamped on the inner wall of the lateral offset limiting hole, 1420 provides support and restraint, effectively improving the lateral shaking amplitude of the clamping support member 1420 and the lateral locking member 1440, and can effectively improve the mechanism damage and equipment failure caused by the rollover of the clamping assembly 120 (such as the jacking clamp) in the clamping mechanism 10, and also reduce the safety hazards to the production of battery cells. In addition, the workpiece shifting device has the advantages of simple structure, space saving and low cost, and can solve the problem that the lifting supporting member 2220 (such as the jacking supporting plate) and the supporting member (such as the clamping supporting bottom plate) are tilted and overturned due to the small contact surface, which causes the supporting mechanism to be suspended more in the air.

[0046] The workpiece displacement device provided in the present embodiment, when taking out the battery core after the top cover welding is completed, the clamping assembly 120 in the clamping mechanism 10 can clamp the workpiece and be set on the supporting limit assembly 140; the lifting mechanism 20 can be clamped on the supporting limit assembly 140, so as to realize the relative position constraint between the supporting limit assembly 140 in the clamping mechanism 10 and the lifting mechanism 20. Compared with the traditional limiting method which only relies on the pin sleeve in the clamping mechanism 10 and the pin in the lifting mechanism 20, the clamping mechanism 10 and the lifting mechanism 20 are effectively increased. The mechanism 20 has a position constraint effect in the horizontal direction, that is, position constraints are performed in the horizontal and vertical directions at the same time to limit the swing amplitude of the clamping mechanism 10 and the lifting mechanism 20, thereby ensuring the movement coordination of the clamping mechanism 10 and the lifting mechanism 20, and improving the problem of the supporting mechanism being suspended in the air due to the small contact surface of the supporting mechanism and the lifting mechanism 20 when only relying on the pin and pin assembly method, resulting in tilting and overturning. While improving the stability of the battery cell material extraction during the battery cell production process, it meets the higher requirements for battery cell production efficiency.

[0047] The present application also provides a processing equipment, which includes the workpiece shifting device in the above-mentioned embodiment; the processing equipment also includes a large equipment plate, a fixture auxiliary driving device and a fixture translational carrying device, the workpiece shifting device and the fixture translational carrying device are arranged on the large equipment plate, the fixture auxiliary driving device is arranged on the fixture translational carrying device, and the fixture auxiliary driving device can fine-tune the clamping state of the battery cell.

[0048] like Figure 2 As shown, when the battery cell after the top cover welding is completed is taken out, the clamping assembly in the supporting mechanism can clamp the battery cell and be set on the supporting limit assembly 140, and the jacking drive assembly 240 in the jacking mechanism 20 can drive the jacking limit assembly 220 to be clamped on the supporting limit assembly 140 in the clamping mechanism 10, so as to realize the relative position constraint between the supporting limit assembly 140 and the jacking limit assembly 220; then the jacking drive assembly 240 in the jacking mechanism 20 drives the battery cell in the clamped state to the fixture translation bearing device, and fine-tunes the clamping state of the battery cell under the driving action of the fixture auxiliary drive device.

[0049] The division of the various modules in the above-mentioned workpiece shifting device is only for illustration. In other embodiments, the workpiece shifting device can be divided into different modules as needed to complete all or part of the functions of the above-mentioned workpiece shifting device.

[0050] The workpiece shifting device and processing equipment provided in the above-mentioned embodiments can clamp the workpiece and be set on the supporting limit assembly when taking out the battery cell after the top cover welding is completed; the lifting mechanism can be clamped on the supporting limit assembly to realize the relative position constraint between the supporting limit assembly and the lifting mechanism in the clamping mechanism. Compared with the traditional limiting method that only relies on the pin sleeve in the clamping mechanism and the pin in the lifting mechanism, the position constraint effect of the clamping mechanism and the lifting mechanism in the horizontal direction is effectively increased, that is, the position constraint is performed in the horizontal direction and the vertical direction at the same time to limit the shaking amplitude of the clamping mechanism and the lifting mechanism, thereby ensuring the movement coordination of the clamping mechanism and the lifting mechanism, and improving the problem of the supporting mechanism being suspended more and tilting and overturning due to the small contact surface of the supporting mechanism and the lifting mechanism when only relying on the pin and pin sleeve assembly method. While improving the stability of battery cell taking out during battery cell production, it can meet the higher requirements of battery cell production efficiency, and has important economic value and promotion and practical value.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0052] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed 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.
