Abstract
Description
Technical Field
[0001] The present application relates to the field of clamping devices, and in particular to a clamping device and a conveying device. Background Art
[0002] During the manufacturing process, battery cells are stacked into groups to form modules, which are then transported into the PACK box by a transport clamp. During the module placement process, the pressing mechanism pushes the module into the box, causing direct sliding and friction between the clamp's claws and the module end plates, which can cause some damage to the end plates. Since the claws are usually made of insulating materials to increase friction and ensure reliable clamping of the module, the design thrust of the pressing mechanism must be large enough, resulting in a high cost for the pressing mechanism and high friction loss of the claws. Furthermore, the friction between the two ends of the module and the clamp is large, making it easy for the module to collapse in the middle and bulge at both ends after being pressed down. This can cause misalignment of different battery cells in the module, and the contact between different battery cells and the box in a certain order, resulting in relatively poor flatness of the bottom of the module.

Obviously, the embodiments described are only part of the embodiments of this application, not all of them.

[0035] Example 1
[0036] See also Figures 1 to 4 As shown, the clamping device provided in this application can be used to transport battery modules into PACK boxes. The clamping device includes multiple clamping mechanisms 101 arranged opposite to each other. The clamping mechanisms 101 can be arranged in pairs, and the opposing clamping mechanisms 101 can approach each other to clamp the product 102.
[0037] The clamping mechanism 101 includes a first clamping component 103 and a second clamping component 104; the first clamping component 103 includes at least one rolling element 105, and the rolling element 105 can reciprocate relative to the second clamping component 104 so that one of the first clamping component 103 or the second clamping component 104 applies pressure to the product 102; the product 102 pressurized by the first clamping component 103 can move along the rolling direction of the rolling element 105 to disengage from the first clamping component 103.
[0038] Specifically, when the clamping device clamps the battery module, the rolling element 105 can move relative to the second clamping assembly 104 in a direction away from the battery module, so that the second clamping assembly 104 applies pressure to the battery module, thereby ensuring that the battery module is clamped tightly. At this time, the clamping device can move and transport the battery module. When the battery module moves to the entrance of the PACK box, the rolling element 105 can move relative to the second clamping assembly 104 in a direction close to the battery module, so that the rolling element 105 of the first clamping assembly 103 applies pressure to the battery module. When the battery module is subjected to downward pressure, the battery module can move downward along the rolling direction of the rolling element 105, and then enter the PACK box from the entrance.
[0039] In other words, during the rolling process of the battery module, the rolling friction between the battery module and the rolling element 105 is relatively low, thus preventing wear on the battery module and the rolling element 105. This low friction also reduces the need for a high downward force on the battery module, thereby reducing the cost of the downward pressure mechanism 117. Furthermore, after the battery module is pressed downward, it is less likely to collapse in the middle or bulge at the ends, thereby improving the quality of the product 102.
[0040] In an optional solution of this embodiment, the first clamping assembly 103 also includes a driving device 106; the driving device 106 is specifically a cylinder, and the driving end of the driving device 106 is connected to the rolling element 105 to drive the rolling element 105 to approach or move away from the product 102, so that the main force point of the battery module is on the rolling element 105 during the process of being pressed into the box.
[0041] In an optional solution of this embodiment, the first clamping assembly 103 also includes a fixed seat 107 and a limiting guide rail 108; the driving device 106 is installed on the fixed seat 107, and the fixed seat 107 is connected to the second clamping assembly 104; the driving end of the driving device 106 is connected to the limiting guide rail 108, and the limiting guide rail 108 is connected to the rolling element 105; the fixed seat 107 is provided with a limiting hole 109 to limit the limiting guide rail 108.
[0042] In this embodiment, specifically Figures 2 to 4 As shown, the second clamping assembly 104 includes a mounting plate 114 and an insulating pad 115. The insulating pad 115 is mounted on the mounting plate 114 and positioned corresponding to the rolling element 105 to apply pressure to the battery module. The fixing seat 107 includes a connecting post 120 and two fixing plates 119. The two fixing plates 119 are spaced apart on the side of the mounting plate 114 facing away from the battery module, and the drive device 106 is mounted between the two fixing plates 119. The fixing plate 119 near the mounting plate 114 has a through hole, and the connecting post 120 extends through the through hole to connect the mounting plate 114 and the drive device 106, thereby fixing the relative positions of the second clamping assembly 104, the fixing seat 107, and the drive device 106.
[0043] Furthermore, the limiting guide rail 108 includes a connecting rod 121 and two limiting rods 122. A through-hole is defined in the fixed plate 119, which is located away from the mounting plate 114. The drive rod of the drive device 106 passes through the through-hole and connects to the connecting rod 121. The two limiting rods 122 are spaced apart, and one end of each limiting rod 122 is connected to the connecting rod 121. The two fixed plates 119 have limiting holes 109 defined therein. The other ends of the two limiting rods 122 pass through corresponding limiting holes 109 in the fixed plates 119 and connect to the rolling element 105. When the drive device 106 drives the rolling element 105 to reciprocate, the limiting rods 122 move along the limiting holes 109 to guide the movement of the rolling element 105.
[0044] In an optional solution of this embodiment, the rolling member 105 includes a connecting portion 110 and a rolling portion 111; the rolling portion 111 is used to apply pressure to the product 102; connecting portions 110 are provided at both ends of the rolling portion 111, and the rolling portion 111 can roll relative to the connecting portion 110; the connecting portion 110 is connected to the driving end of the driving device 106.
[0045] In this embodiment, Figure 3 As shown, the rolling portion 111 is cylindrical, and the connecting portion 110 includes a connecting block and a connecting shaft. The connecting shaft is connected to the connecting block, and the rolling portion 111 is sleeved on the connecting shaft and can rotate relative to the connecting shaft. The end of the limit rod 122 is provided with a connecting plate. The connecting block has a flat surface, so that it can be connected to the surface of the connecting plate.
[0046] In an optional solution of this embodiment, a guide rail structure is provided between the rolling element 105 and the second clamping assembly 104 to further guide the reciprocating motion of the rolling element 105 .
[0047] Specifically, the mounting plate 114 of the second clamping assembly 104 includes a plate body 123 and two stoppers 124. The two stoppers 124 are connected to the lower portion of the plate body 123 and are spaced apart. The guide rail structure comprises guide holes 112 defined in the two stoppers 124. The rolling portion 111 is positioned between the two stoppers 124. The connecting shaft of the connecting portion 110 extends through the guide holes 112 to connect to the rolling portion 111. The length of the guide holes 112 is perpendicular to the clamped surface of the product 102. When the driving device 106 drives the rolling element 105 to reciprocate, the rolling element 105 can reciprocate along the length of the guide holes 112, further guiding the movement of the rolling element 105.
[0048] In an optional solution of this embodiment, the first clamping assembly 103 includes a plurality of rolling elements 105, and the plurality of rolling elements 105 are arranged at intervals along the moving direction of the product 102. The plurality of rolling elements 105 can jointly form a flat clamping surface, thereby fitting with the surface of the battery module, so that the downward movement of the battery module along the plurality of rolling elements 105 is more stable.
[0049] Example 2
[0050] The clamping device in the second embodiment is an improvement on the above embodiment. The technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.
[0051] See also Figure 1 As shown, in an optional solution of this embodiment, the clamping device also includes a main body 113, and the clamping mechanism 101 is mounted on the main body 113. Specifically, the mounting plate 114 is connected to the main body 113. The main body 113 can drive the opposing clamping mechanisms 101 to move closer to or away from each other to clamp or release the battery module. Specifically, the main body 113 includes a clamping claw cylinder, and the driving ends of the clamping claw cylinder are respectively connected to the mounting plates 114 of the opposing clamping mechanisms 101 to drive the clamping mechanisms 101 to move closer to or away from each other.
[0052] Example 3
[0053] Embodiment 3 of the present application provides a transport device, including the clamping device of any of the above embodiments, and thus has all the beneficial technical effects of the clamping device of any of the above embodiments, which will not be repeated here.
[0054] In an optional solution of this embodiment, the conveying equipment also includes a pressing device 116; the pressing device 116 includes a pressing mechanism 117 and an adsorption member 118; the adsorption member 118 is used to adsorb or release the product 102; the pressing mechanism 117 can apply pressure to the product 102 along the moving direction of the product 102 to make the product 102 detach from the clamping device.
[0055] In this embodiment, Figure 1 As shown, the adsorption member 118 is specifically a suction cup, which can be arranged in a one-to-one correspondence with the battery cells of the battery module. In the process of moving the battery module, the second clamping assembly 104 can clamp the battery module from both sides, and the multiple suction cups of the pressing device 116 adsorb the corresponding battery cells from above to ensure that the battery module is securely fixed. When the second clamping assembly 104 clamps the battery module, a portion of the bottom of the battery module needs to be exposed to create conditions for subsequent boxing. When the battery module moves to the entrance of the box, the pressing device 116 presses down on the battery module. At this time, the suction cup breaks the vacuum to release the suction, thereby separating the suction cup from the battery module; the pressing mechanism 117 presses the battery module downward to press it into place, and the boxing is completed.
