[0040] See also Figure 1 and Figure 2 , the clamp provided by the embodiment of the present application is now described. The clamp provided by the embodiment of the present application includes a bracket 5, a first clamping assembly 1, a second clamping assembly 2, a first driving member 3 and a supporting anti-drop assembly 4. The bracket 5 is provided with a first welding hole, the first clamping assembly 1 and the second clamping assembly 2 are relatively arranged on the upper surface of the bracket 5 along the first direction, the first clamping assembly 1 and the second clamping assembly 2 are relatively located on the side of the first welding hole for clamping the workpiece in the first welding hole, the first driving member 3 is connected to the second clamping assembly 2 in a transmission manner, the first driving member 3 is used to drive the second clamping assembly 2 to approach or move away from the first clamping assembly 1 along the first direction, the supporting anti-drop assembly 4 includes a first supporting member 41 and a second supporting member 42, the first supporting member 41 and the second supporting member 42 are relatively arranged in the first welding hole of the bracket 5 along the first direction, the first supporting member 41 is arranged below the first clamping assembly 1, the second supporting member 42 is arranged below the second clamping assembly 2, and the first supporting member 41 and the second supporting member 42 are used to support the falling workpiece.

[0041] The workpiece in the embodiment of the present application can be a battery, a battery cell or other workpiece. The fixture of the present application is mainly used for positioning during pre-welding of the battery top cover, and is generally arranged below the upper positioning plate. When the carrier carrying the battery is transported to the bottom of the fixture, the lifting device lifts the carrier and passes through the first welding hole of the bracket 5 so that the battery in the carrier contacts the upper positioning plate above the fixture to achieve the upper surface positioning of the battery. The first clamping assembly 1 and the second clamping assembly 2 located below the upper positioning plate clamp the battery to achieve the side positioning of the battery. The support anti-drop assembly 4 is located below the first clamping assembly 1 and the second clamping assembly 2 to receive batteries that may fall.

[0042] The first clamping assembly 1 in the embodiment of the present application may include a fixing member and a clamping member. The clamping member is used to abut against one side of the workpiece, and the clamping member is installed on the fixing member.

[0043] The second clamping assembly 2 can adopt the same structure as the first clamping assembly 1, and the fixing member of the second clamping assembly 2 is transmission-connected with the driving assembly. The driving assembly can drive the clamping member on the second clamping assembly 2 to move along the first direction, approaching or moving away from the first clamping assembly 1. The first direction is the horizontal direction.

[0044] The first supporting member 41 supporting the anti-drop assembly 4 may include a supporting portion and a supporting portion, wherein the supporting portion is connected to the supporting portion, and the supporting portion is used to support the falling workpiece, and the supporting portion may be fixedly connected or rotatably connected to the fixing member of the first clamping assembly 1 .

[0045] The second supporting member 42 supporting the anti-drop assembly 4 can adopt the same structure as the first supporting member 41 , and the supporting portion of the second supporting member 42 can be fixedly connected or rotatably connected to the fixing member of the second clamping assembly 2 .

[0046] The first driving member 3 can be one of a cylinder, an electric cylinder or a linear motor. Taking the cylinder as an example, the driving shaft of the cylinder is connected to the second clamping assembly 2, and the cylinder drives the second clamping assembly 2 to approach or move away from the first clamping assembly 1 along the first direction through the driving shaft.

[0047] The supporting anti-drop assembly 4 , the first clamping assembly 1 , the second clamping assembly 2 and the first driving member 3 are all installed on the bracket 5 .

[0048] The supporting anti-drop assembly 4 may also include a second driving member 43, which is installed on the side of the first welding hole. The second driving member 43 is transmission-connected to the first supporting member 41, and the second driving member 43 is used to drive the first supporting member 41 to approach or move away from the second supporting member 42 along the first direction.

[0049] Since the first clamping assembly 1 is not connected to a driving member, the first clamping assembly 1 is used as a reference member in battery positioning. When the carrier carrying the battery is transported to the bottom of the clamp, the lifting device lifts the carrier, passes through the supporting anti-drop assembly 4 and the first clamping assembly 1 and the second clamping assembly 2, and makes the battery in the carrier contact the upper positioning plate above the clamp. Since the first clamping assembly 1 is a reference member, in order to improve positioning efficiency and save time, the position where the lifting device lifts the carrier is close to the first clamping assembly 1. If the position of the first supporting member 41 below the displaced first clamping assembly 1 is fixed, the battery in the carrier is prone to collide with the first supporting member 41 during the rising process of the carrier, resulting in battery damage. The second driving member 43 can make the first supporting member 41 move away from the second supporting member 42 along the first direction when the carrier rises, so that the first supporting member 41 avoids the rising battery to prevent collision with the battery. When the first clamping assembly 1 and the second clamping assembly 2 clamp the battery, the second driving member 43 can make the first supporting member 41 approach the second supporting member 42 along the first direction to prevent the battery from falling.

[0050] The second driving member 43 can be one of a cylinder, an electric cylinder or a linear motor. Taking the cylinder as an example, the driving shaft of the cylinder is connected to the first supporting member 41, and the cylinder drives the first supporting member 41 to approach or move away from the second supporting member 42 along the first direction through the driving shaft.

[0051] Preferably, the first supporting member 41 includes a first connecting portion 411 and a first supporting portion 412 which are vertically connected, the first connecting portion 411 is detachably connected to the second driving member 43, and the first supporting portion 412 is used for supporting a falling workpiece.

[0052] Since different battery specifications will result in different lengths, widths and heights of the batteries, the first supporting member 41 and the second supporting member 42 need to be replaced according to the battery specifications. The detachable connection between the first connecting portion 411 and the second driving member 43 facilitates the replacement of the first supporting member 41. The first connecting portion 411 can be mounted on the driving shaft of the second driving member 43 by bolts.

[0053] A pad 4121 is disposed on a surface of the first supporting portion 412 that is in contact with the workpiece.

[0054] Since the battery will collide with the first supporting part 412 when it falls, in order to prevent the battery from being damaged by the collision, a cushion block 4121 is provided to mitigate the impact of the battery falling, thereby protecting the battery. The cushion block 4121 can be made of elastic materials such as silicone or sponge.

[0055] The end of the first supporting portion 412 close to the second supporting member 42 is provided with a first inclined surface 4122 for facilitating the workpiece to enter the first welding hole.

[0056] Since the pre-welded battery passes between the first supporting member 41 and the second supporting member 42 and moves toward between the first clamping assembly 1 and the second clamping assembly 2, a first inclined surface 4122 is provided on the first supporting portion 412 for guiding and also to prevent the end of the first supporting portion 412 from colliding with the battery.

[0057] Preferably, the second supporting member 42 includes a second connecting portion 421 and a second supporting portion 422 which are vertically connected, the second connecting portion 421 is detachably connected to the second clamping assembly 2, and the second supporting portion 422 is used for supporting a falling workpiece.

[0058] Since different specifications of the battery will result in different lengths, widths and heights of the battery, the first supporting member 41 and the second supporting member 42 need to be replaced according to the specifications of the battery. The second connecting portion 421 is detachably connected to the second clamping assembly 2, which can facilitate the replacement of the second supporting member 42. The second connecting portion 421 can be mounted on the second clamping assembly 2 by bolts. Moreover, since the second clamping assembly 2 is transmission-connected to the first driving member 3, the first supporting member 41 is arranged below the first clamping assembly 1. When the first driving member 3 drives the second clamping assembly 2 to approach or move away from the first clamping assembly 1 along the first direction, the second supporting member 42 can also move along the first direction with the second clamping assembly 2 to approach or move away from the first supporting member 41. When the second supporting member 42 approaches the first supporting member 41 along the first direction, the second supporting member 42 can support the falling battery, and when the second supporting member 42 moves away from the first supporting member 41 along the first direction, the second supporting member 42 can avoid the moving battery.

[0059] The second supporting part 422 is also provided with a pad 4121 on one side thereof for contacting the workpiece, and a first inclined surface 4122 is also provided on the end of the second supporting part 422 close to the first supporting member 41. The structure of the second supporting part 422 is the same as that of the first supporting part 412, so its beneficial effects are not repeated here.

[0061] The material of the first abutment member 13 in the embodiment of the present application can be an elastic material such as silicone or sponge to prevent damage to the battery when clamping the battery. At the same time, since the first abutment member 13 is a consumable part, the detachable connection with the first connecting member 12 can facilitate the replacement of the first abutment member 13. The first abutment member 13 is connected to the first connecting member 12 by bolts. The mounting seat 11 is installed on the bracket 5.

[0062] The first clamping assembly 1 also includes a mounting screw, the mounting seat 11 is provided with a mounting hole for threaded connection with the mounting screw, the first connecting member 12 is provided with a waist-shaped hole, the mounting screw is inserted into the waist-shaped hole and threadedly connected with the mounting hole to install the first connecting member 12 on the mounting seat 11.

[0063] Since the first clamping assembly 1 is a reference member for positioning the battery, the reference position for positioning batteries of different specifications may be slightly adjusted.

[0064] The length direction of the waist-shaped hole on the first connecting member 12 in the embodiment of the present application is the first direction. The first connecting member 12 adjusts the distance between the first abutting member 13 and the second clamping assembly 2 along the first direction to adjust the reference position of the battery positioning. The mounting bolt is threadedly connected to the mounting hole, and the head of the mounting bolt abuts against the edge of the waist-shaped hole of the first connecting member 12, which can fix the position of the first connecting member 12 on the mounting seat 11. Loosen the mounting bolt so that the head of the mounting bolt does not abut against the edge of the waist-shaped hole on the first connecting member 12, and the position of the first connecting member 12 on the mounting seat 11 can be adjusted to adjust the reference position of the battery positioning.

[0065] The mounting seat 11 is provided with a mounting groove 111 for accommodating the first connecting member 12 .

[0066] The mounting hole in the embodiment of the present application is disposed in the mounting groove 111 , the length direction of the mounting groove 111 is the first direction, and the first connecting member 12 can adjust the reference position of the battery positioning along the length direction of the mounting groove 111 .

[0067] A second inclined surface 131 is provided on the end of the first abutment member 13 close to the second clamping assembly 2 to facilitate the workpiece to enter the first welding hole.

[0068] Since the pre-welded battery passes between the first supporting member 41 and the second supporting member 42 and moves toward between the first clamping assembly 1 and the second clamping assembly 2, a second inclined surface 131 is provided on the first abutting member 13 for guiding and also to prevent the end of the first abutting member 13 from colliding with the battery.

[0069] Preferably, the second clamping assembly 2 includes a second connecting member and a second abutting member, the second connecting member is mounted on the first driving member 3, the second connecting member and the second abutting member are detachably connected, and the second abutting member is used to abut against the workpiece. The second connecting portion 421 of the second supporting member 42 is detachably connected to the second connecting member of the second clamping assembly 2.
