[0002] During the welding of the battery top cover, to prevent welding fumes or spatter from contaminating the battery terminals and explosion-proof valve, a battery protective cover is typically placed on the top cover to cover the battery terminals and explosion-proof valve. This protective cover is then removed after welding is complete. Related technologies usually use a pick-and-place device to remove and place the battery protective cover; however, these devices often have low positioning accuracy, failing to guarantee the accurate assembly of the battery protective cover.

[0009] The first direction is set at an angle to the vertical direction.

[0010] Furthermore, the elastic clamping mechanism includes a mounting plate, a pressure plate, and a first elastic member. The mounting plate is disposed on the clamping mechanism and located on the side of the battery protective cover away from the abutment member. One end of the first elastic member abuts against the mounting plate, and the other end abuts against the pressure plate, for providing elastic force to push the pressure plate to elastically abut against the other side of the battery protective cover along the vertical direction.

[0011] Furthermore, the elastic clamping mechanism also includes a first guide member, one end of which is connected to the pressure plate, and the other end of which can be movably mounted on the mounting plate along the second vertical direction.

[0012] Furthermore, the clamping mechanism includes:

[0013] A clamping drive assembly is disposed on the lifting motion mechanism; and

[0014] Two clamping components are spaced apart on the clamping drive component along the first direction. The clamping drive component drives the two clamping components to move along the first direction to clamp the battery cover on both sides along the first direction.

[0015] The abutment is disposed on at least one of the clamping components;

[0016] The elastic clamping mechanism is disposed on the clamping drive assembly and is located on the side of the battery protective cover away from the abutment.

[0017] Furthermore, the clamping assembly includes:

[0018] A mounting base is disposed on the clamping drive assembly; and

[0019] A gripper is disposed on the mounting base, the gripper including a clamping portion for abutting against the side edge of the battery cover along the first direction;

[0020] The abutment is disposed on the gripper, and the free end of the abutment protrudes from the gripping portion along the first direction.

[0021] Furthermore, the battery protective cover has grooves on both sides along the first direction that abut against the clamping part, and the outer contour shape of the clamping part is adapted to the inner contour shape of the groove.

[0022] Furthermore, the lifting mechanism includes:

[0023] Lifting drive mechanism; and,

[0024] The lifting frame is connected to the lifting drive mechanism, which drives the lifting frame to move up and down along the vertical direction.

[0025] The clamping mechanism is mounted on the lifting frame.

[0026] Furthermore, the pick-and-place device also includes:

[0027] A second guide member, one end of which is connected to the clamping mechanism, and the other end which is movably mounted on the lifting frame along the vertical direction; and...

[0028] The second elastic element is sleeved outside the second guide element, with one end of the second elastic element abutting against the lifting frame and the other end abutting against the clamping mechanism, for providing elastic force to buffer the impact force of the clamping mechanism on the battery protection cover.

[0029] Furthermore, the clamping mechanism includes at least two clamping mechanism components, which are spaced apart on the lifting frame along the first direction.

[0030] The pick-and-place device further includes an adjustment mechanism, and at least one of the clamping mechanisms is disposed on the adjustment mechanism to adjust the displacement of the clamping mechanism along the first direction.

[0031] Furthermore, the adjustment mechanism includes:

[0032] An adjusting frame, wherein the adjusting frame has a connecting hole, and the lifting frame has an adjusting groove extending along the first direction; and,

[0033] An adjusting member that passes through any position of the adjusting groove and connects to the connecting hole;

[0034] At least one of the clamping mechanisms is disposed on the adjusting frame.

[0035] The beneficial effects of the pick-and-place device provided in this application embodiment are as follows: When it is necessary to remove the battery cover, the lifting motion mechanism drives the clamping mechanism to descend vertically so that the clamping mechanism clamps the battery cover on both sides along the first direction. Then, the lifting motion mechanism drives the clamping mechanism to rise vertically. At this time, under the action of the elastic force of the elastic pressing mechanism, the battery cover elastically abuts against the abutment. When it is necessary to place the battery cover, the lifting motion mechanism drives the clamping mechanism holding the battery cover to descend vertically and releases the battery cover.

[0036] By setting a clamping mechanism on the lifting motion mechanism to clamp the battery cover on both sides along the first direction, the battery cover can be clamped and fixed along the first direction. In addition, an abutment and an elastic pressing mechanism are set on the clamping mechanism. The abutment abuts against one side of the battery cover in the vertical direction. The elastic pressing mechanism elastically presses the battery cover onto the abutment, thereby achieving the vertical positioning of the battery cover, improving the positioning accuracy, and thus improving the assembly accuracy of the battery cover.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0050] Please see Figure 1 and Figure 5 The following describes the pick-and-place device provided in the embodiments of this application. The pick-and-place device provided in the embodiments of this application is used for picking up and placing the battery protective cover 100, that is, for placing the battery protective cover 100 on the battery top cover, or for removing the battery protective cover 100 from the battery top cover.

[0051] The loading and unloading device includes a lifting mechanism 10, a clamping mechanism 20, an abutment member 30, and an elastic pressing mechanism 40. The clamping mechanism 20 is disposed on the lifting mechanism 10 and is driven by the lifting mechanism 10 to move up and down in the vertical direction. The clamping mechanism 20 is used to clamp the battery protection cover 100 on both sides along a first direction.

[0052] The abutment 30 is disposed on the clamping mechanism 20 and is used to abut against one side of the battery protection cover 100 in the vertical direction.

[0053] The elastic clamping mechanism 40 is disposed on the clamping mechanism 20 and located on the side of the battery cover 100 away from the abutment 30, and is used to provide elastic force to elastically hold the battery cover 100 against the abutment 30.

[0054] The first direction is set at an angle to the vertical direction; for example, the first direction can be set at 90° to the vertical direction. Please refer to [link / reference]. Figure 1 The "first direction" is represented by the X-axis, and the "vertical direction" is represented by the Y-axis.

[0055] The operation process of the pick-and-place device provided in this application embodiment is as follows:

[0056] When the battery protective cover 100 on the battery top cover needs to be removed, firstly, the lifting mechanism 10 drives the clamping mechanism 20 to descend vertically; when the clamping mechanism 20 descends to the first preset position, the elastic pressing mechanism 40 elastically abuts against the battery protective cover 100 on the side away from the abutment 30; then, the clamping mechanism 20 clamps the battery protective cover 100 on both sides along the first direction; then, the lifting mechanism 10 drives the clamping mechanism 20 to rise vertically, and at this time, under the action of the elastic force of the elastic pressing mechanism 40, the battery protective cover 100 is elastically abutted against the abutment 30, thereby improving the positioning accuracy of the battery protective cover 100.

[0057] When it is necessary to place the battery protection cover 100 on the battery top cover, firstly, the lifting mechanism 10 drives the clamping mechanism 20 holding the battery protection cover 100 to descend in the vertical direction; when the clamping mechanism 20 descends to the second preset position, the clamping mechanism 20 can release the battery protection cover 100.

[0058] The pick-and-place device provided in this application embodiment clamps the battery cover 100 on both sides along the first direction by setting a clamping mechanism 20 on the lifting motion mechanism 10, thereby achieving clamping and fixing of the battery cover 100 along the first direction. In addition, an abutment 30 and an elastic pressing mechanism 40 are set on the clamping mechanism 20. The abutment 30 abuts against one side of the battery cover 100 along the vertical direction. The elastic pressing mechanism 40 elastically presses the battery cover 100 onto the abutment 30, thereby achieving vertical positioning of the battery cover 100, improving positioning accuracy, and thus improving the assembly accuracy of the battery cover 100.

[0059] Please see Figure 2 and Figure 4 The elastic clamping mechanism 40 may include a mounting plate 41, a pressure plate 42, and a first elastic member 43. The mounting plate 41 is disposed on the clamping mechanism 20 and located on the side of the battery cover 100 away from the abutment 30. One end of the first elastic member 43 abuts against the mounting plate 41, and the other end abuts against the pressure plate 42, providing elastic force to push the pressure plate 42 elastically against the other side of the battery cover 100 in the vertical direction. Through the cooperation of the pressure plate 42 and the first elastic member 43, the pressure plate 42 elastically abuts against the other side of the battery cover 100 in the vertical direction, thereby elastically pressing the battery cover 100 against the abutment 30. Specifically, the first elastic member 43 may be a compression spring.

[0060] Please see Figure 4The elastic clamping mechanism 40 may further include a first guide member 44, one end of which is connected to the pressure plate 42, and the other end is movably mounted on the mounting plate 41 in the vertical direction. The first guide member 44 improves the movement accuracy of the pressure plate 42 and prevents deviation.

[0061] Please see Figure 2 The battery cover 100 has a positioning hole (not shown in the figure). The elastic pressing mechanism 40 may also include a positioning element 45, one end of which is mounted on the mounting plate 41 and the other end is inserted into the positioning hole. Through the cooperation between the positioning element 45 and the positioning hole, the positioning of the battery cover 100 can be better achieved.

[0062] Please see Figure 2 and Figure 3 The clamping mechanism 20 may include a clamping drive assembly 21 and two clamping assemblies 22. The clamping drive assembly 21 is mounted on the lifting motion mechanism 10. The two clamping assemblies 22 are spaced apart on the clamping drive assembly 21 along a first direction. The clamping drive assembly 21 drives the two clamping assemblies 22 to move along the first direction to clamp the battery cover 100 on both sides of the battery cover 100 along the first direction. An abutment 30 is mounted on at least one of the clamping assemblies 22; that is, the abutment 30 may be mounted on one or both clamping assemblies 22. An elastic pressing mechanism 40 is mounted on the clamping drive assembly 21 and located on the side of the battery cover 100 away from the abutment 30. By driving the two clamping assemblies 22 to move along the first direction through the clamping drive assembly 21, the battery cover 100 can be clamped on both sides of the battery cover 100 along the first direction. Compared with using an electromagnet to attract the battery cover 100, the clamping is more stable and reliable. Specifically, the clamping drive assembly 21 may be a cylinder.

[0063] Please see Figure 2 and Figure 5 The clamping assembly 22 may include a mounting base 221 and a gripper 222. The mounting base 221 is disposed on the clamping drive assembly 21. The gripper 222 includes a clamping portion 2221 for abutting against the side edge of the battery cover 100 along a first direction. By using the clamping portion 2221 to abut against the side edge of the battery cover 100 along the first direction, the clamping is more secure and reliable. An abutment member 30 is disposed on the gripper 222, and the free end of the abutment member 30 protrudes from the clamping portion 2221 along the first direction, thereby facilitating abutment against one side of the battery cover 100 along the vertical direction. Specifically, the clamping member and the gripper 222 can be integrally formed, which simplifies the manufacturing process and effectively reduces costs.

[0064] Please see Figure 3 and Figure 5The battery cover 100 has grooves 110 on both sides along the first direction that abut against the clamping part 2221. The outer contour shape of the clamping part 2221 matches the inner contour shape of the groove 110, so that they can fit better and clamp more firmly. Specifically, the outer contour shape of the clamping part 2221 can be V-shaped, and the inner contour shape of the groove 110 can also be V-shaped.

[0065] Please see Figure 1 and Figure 6 The lifting mechanism 10 may include a lifting drive mechanism 11 and a lifting frame 12. The lifting frame 12 is connected to the lifting drive mechanism 11, and the lifting drive mechanism 11 drives the lifting frame 12 to move up and down in the vertical direction. The clamping mechanism 20 is mounted on the lifting frame 12. Specifically, the lifting drive mechanism 11 may be a cylinder or a motor. By driving the lifting frame 12 to move up and down through the lifting drive mechanism 11, the clamping mechanism 20 is also driven to move up and down, thereby allowing the height of the clamping mechanism 20 to be adjusted.

[0066] Please see Figure 6 The pick-and-place device may further include a second guide member 50 and a second elastic member 60. One end of the second guide member 50 is connected to the clamping mechanism 20, and the other end is movably mounted on the lifting frame 12 in the vertical direction. The second elastic member 60 is sleeved on the second guide member 50, with one end abutting against the lifting frame 12 and the other end abutting against the clamping mechanism 20, providing elastic force to buffer the impact force of the clamping mechanism 20 on the battery protection cover 100. When the clamping mechanism 20 descends too far, it will collide with the battery protection cover 100. Due to the arrangement of the second guide member 50 and the second elastic member 60, the clamping mechanism 20 will retract, thereby buffering the impact force on the battery protection cover 100.

[0067] Please see Figure 1 The clamping mechanism 20 may include at least two, which are spaced apart on the lifting frame 12 along a first direction. By providing at least two clamping mechanisms 20, multiple battery protection covers 100 can be picked up and put on simultaneously, thereby improving work efficiency. When there are two clamping mechanisms 20, two lifting frames 12 may also be provided, with each clamping mechanism 20 respectively provided on a corresponding lifting frame 12.

[0068] like Figure 6 As shown, the pick-and-place device may also include an adjustment mechanism, with at least one clamping mechanism 20 disposed on the adjustment mechanism to adjust the displacement of the clamping mechanism 20 along the first direction, thereby adjusting the spacing between different clamping mechanisms 20, and thus making it applicable to the pick-and-place of battery protection covers 100 of different sizes, with a wider range of applications.

[0069] Please see Figure 6The adjustment mechanism may include an adjustment frame 70 and an adjustment component (not shown in the figure). The adjustment frame 70 has a connecting hole (not shown in the figure), and the lifting frame 12 has an adjustment groove 121 extending along a first direction. The adjustment component passes through any position in the adjustment groove 121 and connects to the connecting hole. At least one clamping mechanism 20 is disposed on the adjustment frame 70. When it is necessary to adjust the displacement of the clamping mechanism 20 along the first direction, simply loosen the adjustment component, move it along the adjustment groove 121 to the appropriate position, and then connect the adjustment component to the connecting hole. The adjustment is very simple and convenient. Specifically, the adjustment component can be an adjustment screw, and the connecting hole can be a threaded hole.

[0070] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
