[0042] Example 1

[0043] See also Figures 1 to 5As shown, the battery cell carrying robot provided in the present application includes a mounting seat 101, a first supporting mechanism and a second supporting mechanism.

[0044] The first supporting mechanism is connected to the mounting base 101, and the first supporting mechanism includes two first supporting assemblies 102 arranged opposite to each other. The two first supporting assemblies 102 can move closer to or farther away from each other to support or release the battery cell 103 at both ends in the first direction. Specifically, the first direction is the length direction of the battery cell 103, and the two curved side edges of the battery cell 103 are arranged opposite to each other along the length direction of the battery cell 103. When the battery cell 103 is transported, the two first supporting assemblies 102 can move closer to each other to support the battery cell 103 at both ends in the length direction. When the battery cell 103 is transported to its place, the two first supporting assemblies 102 can move away from each other to release the battery cell 103.

[0045] When the length of the battery cell 103 is large, for example, when the length of the battery cell 103 exceeds 250 mm, the middle part of the battery cell 103 in the length direction will collapse, which will have an adverse effect on the subsequent positioning of the battery cell 103 and may cause the battery cell 103 to be bruised, crushed, etc. In order to solve the above problems, the present application provides a second supporting mechanism. Specifically, the second supporting mechanism is connected to the mounting seat 101, and the second supporting mechanism includes a second supporting assembly 104. The second supporting assembly 104 is located between the two first supporting assemblies 102, and the second supporting assembly 104 can be close to or away from the battery cell 103. When the battery cell 103 is transported, the second supporting assembly 104 can be close to the battery cell 103 to support the battery cell 103 at one position along the length direction, thereby preventing the battery cell 103 from collapsing. When the battery cell 103 is transported to its place, the second supporting assembly 104 can be away from the battery cell 103 to release the battery cell 103.

[0046] In an optional solution of this embodiment, the second supporting assembly 104 includes a second driving mechanism and a supporting member 108 ; the second driving mechanism includes a first driving device 105 , a connecting bracket 106 and a second driving device 107 .

[0047] The supporting member 108 is located at one end of the battery cell 103 in the second direction and is used to support the middle part of the battery cell 103 in the first direction; the second driving device 107 is installed on the connecting bracket 106, and the driving end of the second driving device 107 is connected to the supporting member 108 to drive the supporting member 108 to approach or move away from the battery cell 103 along the second direction, and the first direction and the second direction are both located in the horizontal plane and intersect with each other; the first driving device 105 is installed on the mounting base 101, and the driving end of the first driving device 105 is connected to the connecting bracket 106 to drive the connecting bracket 106 to move along the third direction. Any two of the first direction, the second direction and the third direction are perpendicular to each other.

[0048] In this embodiment, Figure 1 and Figure 2 As shown, when the first and second supporting mechanisms support the battery cell 103, the large surface of the battery cell 103 (formed by the length and width of the battery cell 103) is placed horizontally. The second direction is the width direction of the battery cell 103, and the second direction and the first direction are located in a horizontal plane. The third direction is the thickness direction of the battery cell 103, and the third direction is the vertical direction.

[0049] When the second supporting mechanism supports the battery cell 103, the supporting member 108 can support the middle portion of the battery cell 103 in the longitudinal direction to achieve a better supporting effect. Specifically, the second driving mechanism includes a first driving device 105, a connecting bracket 106, and a second driving device 107. The first driving device 105 is specifically a cylinder and is used to drive the supporting member 108 to move up and down. The second driving device 107 is specifically a cylinder and is used to drive the supporting member 108 to move horizontally. The supporting member 108 can move in two vertical directions to support or release the battery cell 103.

[0050] In an optional solution of this embodiment, the second supporting assembly 104 further includes a first guide rail 109 and a second guide rail 110 .

[0051] The first guide rail 109 guides in the third direction and is used to guide the lifting movement of the supporting member 108. Specifically, the first guide rail 109 includes a first slide rail and a first slider slidably mounted on the first slide rail. The first slide rail is mounted on the mounting base 101, and the first slider is connected to the connecting bracket 106 to guide the movement of the connecting bracket 106.

[0052] The second guide rail 110 guides in a second direction and is used to guide the translational movement of the support member 108. The second guide rail 110 includes a second slide rail and a second slider slidably mounted on the second slide rail. The second slide rail is mounted on the connecting bracket 106, and the second slider is connected to the support member 108 to guide the movement of the support member 108.

[0053] In an optional solution of this embodiment, the support member 108 includes an adjustable beam 111 and a tab pressing roller 123. The drive end of the second drive device 107 is connected to the adjustable beam 111, and the tab pressing roller 123 is connected to the adjustable beam 111, allowing the tab pressing roller 123 to rise and fall and translate. The tab pressing roller 123 is primarily used to flatten and then press the tab 115 of the battery cell 103 to prevent the tab 115 from folding during movement.

[0054] Specifically, the second end face 114 of the battery cell 103 is located at one end in the width direction of the battery cell 103, and a tab 115 is extended from the second end face 114. A tab pressing roller 123 is located at the second end face 114. When the second drive device 107 drives the adjustment beam 111 to move, the pressing portion of the tab pressing roller 123 flattens and presses the tab 115, thereby preventing the tab 115 from folding.

[0055] In an optional solution of this embodiment, the tab pressing roller 123 includes a second connecting member 124 and a pressing roller member 125. The second connecting member 124 is movably connected to the adjustment beam 111 to adjust its installation position along the length of the adjustment beam 111. Preferably, the second connecting member 124 is provided on both sides of the adjustment beam 111. The pressing roller member 125 is rotatably mounted on the second connecting member 124 to form a pressure-applying portion.

[0056] In this embodiment, when the battery cell carrying robot picks up battery cells 103 of different sizes, the positions of the tabs 115 of battery cells 103 of different sizes are also different. The connection position of the second connecting member 124 and the adjusting beam 111 can be adjusted according to the position of the tab 115 of the battery cell 103, so that the pressure roller 125 can be opposite to the tab 115, so that the pressure roller 125 can flatten and pressurize the tab 115.

[0057] like Figure 5 As shown, the adjustment beam 111 is provided with a plurality of first positioning holes 117 and a plurality of first connection holes 118. The first connection holes 118 and the first positioning holes 117 are sequentially interspersed along the length of the adjustment beam 111. The second connecting member 124 is provided with a fourth positioning hole 126 and a fourth connection hole 127. The fourth positioning hole 126 and the fourth connection hole 127 are spaced apart in the horizontal direction. Depending on the position of the tab 115 of the battery cell 103, the fourth connection hole 127 of the second connecting member 124 can be connected to one of the first connection holes 118 of the adjustment beam 111 via a bolt, and the fourth positioning hole 126 can be connected to one of the first positioning holes 117 of the adjustment beam 111 via a bolt. This allows the position of the pressure roller 125 to be adjusted for different types of battery cells 103.

[0058] In an optional solution of this embodiment, the pressure roller member 125 includes a rotating shaft 128, a fixed portion 129 and an extended portion 130; the rotating shaft 128 is connected to the second connecting member 124, the fixed portion 129 is cylindrical and is sleeved on the rotating shaft 128; at least one of the two ends of the fixed portion 129 is provided with an extended portion 130; the extended portion 130 includes two splicing parts 131, the splicing parts 131 are semi-cylindrical, and the two splicing parts 131 are connected to form a cylindrical structure and are sleeved on the rotating shaft 128.

[0059] In this embodiment, in order to be compatible with more battery cell 103 blueprints, the pressing roller 125 is configured as a length-adjustable structure. Figure 5As shown, an extension portion 130 is provided at each end of the fixing portion 129. The extension portion 130 is formed by two semi-cylindrical spliced ​​pieces 131 connected by magnetic attraction. The extension portion 130 is also connected to the fixing portion 129 by magnetic attraction. The length of the fixing portion 129 can be set according to the length of the extended area of ​​the tab 115 of the smallest blueprint battery cell 103. When transporting large-sized blueprint battery cells 103, the length of the pressure roller 125 can be extended as needed. Specifically, the maximum length of the pressure roller 125 is 120 mm, which is compatible with all battery cells 103 with a tab 115 extended area length of less than 120 mm.

[0060] In an optional solution of this embodiment, the battery cell carrying robot further includes a withstand voltage tester, and a test probe of the withstand voltage tester is electrically connected to the tab pressing roller 123 .

[0061] In this embodiment, a HiPot tester can be installed behind the manipulator, and the two manipulators can share one HiPot tester, reducing the number of testers and lowering costs. Specifically, the test line length is ≤1.2m to reduce the proportion of false positives and improve the quality rate of battery cells 103. The detection probe of the HiPot tester is directly connected to the tab pressing roller 123. During the process of transporting the battery cells 103, the tab pressing roller 123 presses the tab 115 to perform the HiPot test.

[0065] In this embodiment, the first end face 113 is on the opposite side of the second end face 114 , that is, the second end face 114 is located at the other end in the width direction of the battery cell 103 , and the supporting claw 112 is located at the first end face 113 to support the battery cell 103 without interfering with other components.

[0066] In an optional solution of this embodiment, the supporting claw 112 is movably connected to the adjusting beam 111 to change its own installation position in the length direction of the adjusting beam 111; the length direction of the adjusting beam 111 is the second direction of the battery cell 103.
