[0036] Embodiment one
[0037] The gripping assembly 102 provided by the present application is used to place the workpiece in the shell piece 105, and can be specifically applied to the production process of cylindrical batteries. The gripping assembly 102 is used to place the busbar 104 into the cylindrical battery shell.
[0038] Referring to Figures 1 to 6 The gripping assembly 102 provided by the present application includes:
[0039] The suction accessory 108 is used to pick up or release the workpiece, so as to realize the transportation and transfer of the workpiece.
[0040] The positioning piece 103 is circumferentially arranged around the suction accessory 108. The positioning piece 103 has a containing cavity 121, and the picked-up workpiece is located in the containing cavity 121. The containing cavity 121 is matched with the workpiece to position the picked-up workpiece during movement.
[0041] Specifically, when the workpiece is the busbar 104 and the shell piece 105 is a battery shell, the positioning piece 103 is provided in a structure similar to a "sleeve cup", and the shape and size of the accommodation cavity 121 inside the positioning piece 103 are designed in a shape similar to the shape and size of the busbar 104. When the grabbing assembly 102 picks up the busbar 104, the suction accessory 108 adsorbs and picks up the busbar 104, and at this time, the positioning piece 103 is arranged around the circumference of the busbar 104 to position the busbar 104. During the movement of the busbar 104 by the grabbing assembly 102, the busbar 104 is positioned by being adsorbed by the suction accessory 108, and the busbar 104 is always inside the accommodation cavity 121, so that the positioning state of the busbar 104 is not easy to loosen and deviate.
[0042] Optionally, the difference between the radius of the accommodation cavity 121 and the radius of the busbar 104 is greater than or equal to 0.12 mm and less than or equal to 0.17 mm. In this way, the positioning effect of the positioning piece 103 on the busbar 104 can be avoided, and the busbar 104 can be prevented from being difficult to enter the accommodation cavity 121. Specifically, the difference between the radius of the accommodation cavity 121 and the radius of the busbar 104 can be 0.12 mm, 0.122 mm, 0.124 mm, 0.125 mm, 0.126 mm, 0.128 mm, 0.13 mm, 0.135 mm, 0.14 mm, 0.146 mm, 0.15 mm, 0.158 mm, 0.16 mm, 0.165 mm, 0.167 mm or 0.17 mm, but is not limited to the listed values, and other values not listed in the value range are also applicable.
[0043] The grabbing assembly 102 provided by the application can position the busbar 104 by arranging the positioning piece 103 around the circumference of the suction accessory 108, so that the positioning piece 103 can position the busbar 104 during the adsorption and movement of the busbar 104 by the suction accessory 108, to ensure that the busbar 104 does not deviate during movement.
[0044] In the optional scheme of this embodiment, as shown in Figure 2 and Figure 3 The positioning piece 103 has a bottom wall 119 and a side wall 120, and the bottom wall 119 and the side wall 120 jointly define an accommodation cavity 121, and the side wall 120 is arranged around the circumference of the suction accessory 108; the accommodation cavity 121 is adapted to the shell piece 105, so that the positioning piece 103 can be sleeved around the circumference of the shell piece 105.
[0045] In this embodiment, when the grabbing assembly 102 moves the busbar 104 to the shell piece 105, the positioning piece 103 can be sleeved around the shell piece 105, so that the busbar 104 can be concentric with the shell piece 105 during the movement of the busbar 104 into the shell, to facilitate the entry of the busbar 104 into the shell piece 105.
[0046] Optionally, the difference between the radius of the accommodating cavity 121 and the radius of the outer wall of the shell member 105 is greater than or equal to 0.08 mm and less than or equal to 0.1 mm. In this way, the difference is avoided from being too large to affect the concentric positioning of the positioning member 103 and the shell member 105, and the difference is also avoided from being too small to cause the positioning member 103 to be difficult to be sleeved on the circumference of the shell member 105. Specifically, the difference between the radius of the accommodating cavity 121 and the radius of the outer wall of the shell member 105 can be 0.08 mm, 0.082 mm, 0.085 mm, 0.087 mm, 0.09 mm, 0.092 mm, 0.094 mm, 0.096 mm, 0.098 mm or 0.1 mm, but is not limited to the listed values, and other unlisted values within the value range are also applicable.
[0047] In the optional scheme of this embodiment, the side wall 120 is provided with an avoiding groove 109 at the end away from the bottom wall, the avoiding groove 109 extends along the height direction of the positioning member 103 and penetrates the end face of the side wall 120; the suction member 108 can pass through the avoiding groove 109 and reciprocate along the radial direction of the positioning member 103, so that the outer edge of the suction member 108 abuts against the outer edge of the workpiece, to make the outer edge of the workpiece fit the inner wall of the shell member 105.
[0048] In this embodiment, due to the thin material of the busbar 104 itself, the busbar 104 is easily deformed during movement, resulting in a gap between the outer wall of the busbar 104 and the inner wall of the shell member 105 of the cylindrical battery cell, which affects the subsequent welding. Moreover, when the busbar 104 is put into the shell member 105, the busbar 104 is offset, which also causes a gap between the outer wall of the busbar 104 and the inner wall of the shell member 105 of the cylindrical battery cell, which affects the subsequent welding. The application sets that after the busbar 104 is pressed into the shell to be in place, the suction member 108 is disconnected in vacuum, and the suction member 108 moves along the radial direction, so that the outer edge profile of the suction member 108 can expand the busbar 104, to play a role of shaping the busbar 104, so that the outer edge (see Figure 4 of the busbar 104, i.e. the outer wall of the turned-up portion 124 of the busbar 104) is tightly fitted with the inner wall of the shell member 105, to ensure the quality and stability of the subsequent welding.
[0049] In addition, the avoiding groove 109 provided by the positioning member 103 can provide space for the movement of the suction member 108, so that the suction member 108 can expand the busbar 104.
[0050] Specifically as Figure 2 and Figure 3As shown, the number of suction accessories 108 is multiple, and is distributed in a circumferential direction, to collectively suction the busbar plate 104. The positioning member 103 is provided with parallel opening and closing cylinders 107, and after the busbar plate 104 is press-fitted in place, the parallel opening and closing cylinders 107 can drive the multiple suction accessories 108 to move close to or away from each other in the radial direction of the positioning member 103, so as to form a chuck structure in an opening and closing form, to support and reshape the busbar plate 104. The number of avoidance grooves 109 is multiple, and is distributed in a circumferential direction, one suction accessory 108 corresponds to one avoidance groove 109, and each suction accessory 108 can move through the corresponding avoidance groove 109, so as to support the busbar plate 104. During the transfer and assembly of the busbar plate 104 into the shell, the multiple circumferentially distributed suction accessories 108 can ensure that the entire busbar plate 104 is uniformly stressed, and the risk of deformation or deviation of the busbar plate 104 is reduced.
[0051] The grabbing assembly 102 of the embodiment can also be used to place other workpieces in other shell members 105, and the principle is the same, which will not be described herein.
[0052] Embodiment Two
[0053] The grabbing assembly 102 in the embodiment two is an improvement on the basis of the above-mentioned embodiment, and the technical content disclosed in the above-mentioned embodiment will not be described repeatedly, and the content disclosed in the above-mentioned embodiment also belongs to the content disclosed in the embodiment two.
[0054] In an optional scheme of the embodiment, the positioning member 103 is provided with a guide surface 122 at an end of the side wall 120 away from the bottom wall, one end of the guide surface 122 is connected to an end surface of the side wall 120, the other end is connected to an inner surface of the side wall 120, and the guide surface 122 is inclined with respect to the inner surface.
[0055] In the embodiment, referring to Figure 3 As shown, the inner side of the opening of the positioning member 103 is inversely beveled, so that a horn-shaped guide surface 122 structure is formed at this position, and when the positioning member 103 is sleeved on the shell member 105, the guide surface 122 can play a guiding role, so that the sleeving action is easier.
[0056] Embodiment Three
[0057] The embodiment three of the application provides a busbar plate assembly device for assembling a busbar plate 104 into a battery shell. The busbar plate assembly device comprises: the grabbing assembly 102 of any one of the above-mentioned embodiments, the workpiece is the busbar plate 104, the shell member 105 is the battery shell, and the battery shell contains a battery cell 123; and
[0058] The supporting member 106 is used for supporting the bus bar plate 104 which is not picked up, and is cylindrical and has the same outer diameter as the outer diameter of the shell member 105. The accommodating cavity 121 of the positioning member 103 is adapted to the supporting member 106, so that the positioning member 103 can be sleeved around the supporting member 106. In addition, the bus bar plate assembly device further comprises a positioning sleeve 125, and the shell member 105 can be arranged in the positioning sleeve 125, so that the positioning sleeve 125 positions the shell member 105.
[0059] In this embodiment, the supporting member 106 is used for supporting the bus bar plate 104 which is not picked up, and the grabbing assembly 102 can pick up the bus bar plate 104 from the supporting member 106 and move to the battery shell. When the grabbing assembly 102 picks up the bus bar plate 104 from the supporting member 106, the positioning member 103 can be sleeved around the supporting member 106, so that the grabbing assembly 102 can ensure that the bus bar plate 104 is concentric with the positioning member 103 during the picking process, so as to facilitate the bus bar plate 104 to enter the accommodating cavity 121. The shape and size of the supporting member 106 are designed according to the shape and size of the battery shell, so that the concentricity of the bus bar plate 104, the supporting member 106 and the shell member 105 is consistent during the picking and placing processes of the grabbing assembly 102, so that the bus bar plate 104 is not easy to deviate, and the accuracy of positioning is effectively ensured.
[0060] In the optional scheme of this embodiment, the supporting surface of the supporting member 106 for supporting the bus bar plate 104 and the end surface of the battery cell 123 for mounting the bus bar plate 104 are located at the same horizontal plane. During the picking and placing of the bus bar plate assembly device, the grabbing assembly 102 has the same movement distance in the height direction, and the same pressure is applied to the bus bar plate 104, so that the problem of crushing the bus bar plate 104 is not easy to occur, and the risk of deviation of the bus bar plate 104 is further reduced.
[0061] In the optional scheme of this embodiment, the bus bar plate assembly device further comprises a Z-axis driving member for driving the grabbing assembly 102 to reciprocate along the Z-axis, and a buffer member 116 connected between the Z-axis driving member and the grabbing assembly 102 and capable of reciprocating along the Z-axis to buffer the impact force of the grabbing assembly 102 on the supporting member 106 or the battery cell 123.
[0062] In this embodiment, as shown in Figure 5 and Figure 6 The bus bar plate assembly device comprises a driving part 101 and a grabbing assembly 102. The driving part 101 comprises an X-axis cylinder 110 and a Z-axis cylinder 113. The X-axis cylinder 110 can drive the grabbing assembly 102 to move in the X-axis direction, and the Z-axis cylinder 113 can drive the grabbing assembly 102 to move in the Z-axis direction.
[0063] Specifically, the movement process of the busbar assembly device is as follows: after the busbar 104 is placed in the support 106, the X-axis cylinder 110 is retracted, the grabbing assembly 102 is initially positioned by the X-axis limiting member 112 (hydraulic buffer) arranged on the right side, so that the positioning member 103 is in a state of close concentricity with the support 106. The Z-axis cylinder 113 (Z-axis driving member) is extended, the positioning member 103 is lowered to be sleeved on the periphery of the support 106, and the grabbing assembly 102 is guided by the Z-axis linear guide rail 114, so as to ensure that the positioning member 103 is concentric with the support 106. The lowering distance of the positioning member 103 is positioned by the Z-axis limiting member 115, so as to ensure the consistency of repeated lowering. The parallel opening and closing cylinder 107 in the positioning member 103 is in a closed state, the suction member 108 is opened under negative pressure, and the busbar 104 is adsorbed in the positioning member 103. The Z-axis cylinder 113 is retracted to take out the busbar 104 from the support 106. Then the X-axis cylinder 110 is extended to move the grabbing assembly 102, and the grabbing assembly 102 is guided by the X-axis linear guide rail 111 and is coarsely positioned by the X-axis limiting member 112 arranged on the left side, so that the positioning member 103 is in a state of close concentricity with the battery shell. The Z-axis cylinder 113 is extended to press the positioning member 103 to be sleeved with the battery shell, so as to ensure that the positioning member 103 is concentric with the battery shell. The lowering distance of the positioning member 103 is positioned by the Z-axis limiting member 115, so as to ensure the consistency of repeated lowering.
[0064] Further, when the grabbing assembly 102 is pressed down, in order to ensure that the suction member 108 in the positioning member 103 can completely suck the busbar 104, the positioning member 103 needs to have a certain interference amount when it is pressed down. In order to prevent the interference amount from damaging the busbar 104 when it is pressed down, the application is provided with a buffer member 116, which specifically includes a spring 117 arranged between the Z-axis driving member and the grabbing assembly 102. The compression spring 117 can absorb the interference amount when the positioning member 103 is pressed down, and the buffer member 116 further includes a buffer guide rail 118, which can guide the grabbing assembly 102 and avoid the movement direction of the grabbing assembly 102 from being skewed under the action of the spring 117.
