Abstract
Description
Technical Field
[0001] The utility model belongs to the field of lithium battery module manufacturing, and particularly relates to a module anti-drop clamping mechanism. Background Art
[0002] With the continuous increase in consumers' demand for large battery capacity, there are a large number of long modules or multi-column modules in the process of processing and assembling lithium-ion batteries. When it is necessary to transfer long modules or multi-column modules on the production line, a clamping and transferring process is required. Since only an adhesive pasting method is used to paste adjacent battery cells in the existing module, when the existing clamping mechanism performs the clamping and transferring process, only a clamping force is applied to the side of the long module or multi-column module, so there is a risk of displacement or drop of the long module or multi-column module in the vertical direction. Summary of the Utility Model
[0003] In view of the above problems, the utility model provides a module anti-drop clamping mechanism, which can effectively prevent the long module or multi-column module from having displacement or drop in the vertical direction and has higher safety performance.
[0004] In order to achieve the above technical purpose and reach the above technical effect, the utility model is realized by the following technical solutions:
[0005] A module anti-drop clamping mechanism, comprising:
[0006] A tray for placing the module;
[0007] A power component;
[0008] A clamping jaw mechanism located above the tray, comprising a mounting plate connected to the power component, and a power telescopic component is arranged on the mounting plate; a plurality of clamping jaws are arranged at both ends of the power telescopic component; the clamping jaw mechanism is used to cooperate with the power component, so that the clamping jaws at both ends thereof extend into the bottom of the corresponding battery cells in the module, and only one clamping jaw holds up one battery cell, and the module is clamped.
[0009] In the above technical solution, the module is placed on the tray; the power telescopic component in the clamping jaw mechanism drives the clamping jaws at both ends thereof to move, adjusts the opening distance between the clamping jaws at both ends thereof to a suitable value, reaches the specified insertion position, so that the end of the clamping jaw far from the power telescopic component is located outside the module; the power component drives the clamping jaw mechanism to move to the specified clamping position; finally, the power telescopic component drives the clamping jaws at both ends thereof to move, so that the clamping jaws at both ends thereof extend into the bottom of the corresponding battery cells in the module, perform a holding-up action on each battery cell, and clamp the module, which can effectively prevent the long module or multi-column module from having displacement or drop in the vertical direction and has higher safety performance.
[0010] Optionally, a plurality of notches are provided on opposite sides of the tray along the arrangement direction of the battery cells in the module, and the notches on both sides are staggered. The clamping jaws at both ends of the power telescopic member are staggered. The notches are used for the clamping jaws to extend into the bottom of the corresponding battery cells.
[0011] Since during the production of battery cells, adhesive is usually used to paste adjacent battery cells. Therefore, in the above technical solution, by providing staggered notches on both sides of the tray, one clamping jaw can support the bottom of one battery cell in the module, greatly reducing the number of clamping jaws. On the premise of effectively preventing displacement or dropping of a long module or a multi-column module in the vertical direction, the production cost of the anti-drop clamping mechanism for the entire module is reduced.
[0012] Optionally, connecting plates are provided at both ends of the power telescopic member. The connecting plates are perpendicularly connected to the clamping jaws, and the clamping jaws are linear; filling blocks are provided on each clamping jaw. When the clamping jaw extends into the corresponding notch, there is a clearance fit between the filling block and the notch, and the filling block contacts the corresponding battery cell.
[0013] In the above technical solution, when each clamping jaw extends into the bottom of the corresponding battery cell in the module, the filling block is located between the connecting plate and the module, and is closely attached to the side wall of the connecting plate and the module respectively, and can greatly improve the clamping force on the module.
[0014] Optionally, the ratio of the height of the filling block to the height of the corresponding battery cell in the module is greater than a set threshold.
[0015] In the above technical solution, by setting the height of the filling block, the contact area between the filling block and the corresponding battery cell is increased, and finally the clamping force on the module is improved, thereby reducing the requirement for the length of the clamping jaw.
[0016] Optionally, connecting rods are provided at both ends of the power telescopic member. The connecting rods are connected to the clamping jaws, and the clamping jaws are L-shaped.
[0017] In the above technical solution, the L-shaped clamping jaws are used to simultaneously support the bottom of the battery cells in the module and closely fit the side walls of the battery cells, so as to improve the clamping force on the module.
[0018] Optionally, the distance between adjacent clamping jaws is equal to the distance between adjacent notches.
[0019] In the above technical solution, when each clamping jaw extends into the bottom of the corresponding battery cell in the module, there is a clearance fit between the clamping jaw and the corresponding notch, which is beneficial for the clamping jaw to extend in or withdraw, and to increase the area for supporting the bottom of the battery cell.
[0020] Optionally, the total number of clamping jaws at both ends of the power telescopic member is equal to the number of battery cells in the module.
[0021] In the above technical solution, since adjacent battery cells are usually pasted together by means of adhesive tape during the production process of the battery cells, therefore, in the above technical solution, by providing staggered notches on both sides of the tray, a clamping jaw can support the bottom of one battery cell in the module, while greatly reducing the number of clamping jaws, and effectively preventing the long module or multi-column module from having displacement or falling in the vertical direction.
[0022] Optionally, the power telescopic member is a cylinder.
[0023] In the above technical solution, the cylinder can be directly purchased on the market, and the cost is low.
[0024] Optionally, the number of cylinders is greater than or equal to 1. When the number of cylinders is greater than 1, the cylinders are parallel to each other.
[0025] In the above technical solution, it is possible to determine the number of cylinders to be activated according to the actual length of the module, so as to reduce the overall power consumption of the anti-falling clamping mechanism of the module and save electric energy.
[0026] Optionally, the power member includes an X-axis linear drive unit, a Y-axis linear drive unit, a Z-axis linear drive unit, and a rotation unit; the X-axis linear drive unit, the Y-axis linear drive unit, and the Z-axis linear drive unit are connected to each other to form a motion module that can move in the X, Y, and Z axis directions, and the rotation unit is connected to the motion module to drive the motion module to rotate.
[0027] In the above technical solution, through the design of the power member, the clamping jaw mechanism can perform actions such as moving and rotating in the X, Y, and Z directions, so as to complete the clamping and transfer process of the module with multiple degrees of freedom.
[0028] Compared with the prior art, the beneficial effects of the present utility model are:
[0029] The present utility model places the module on the tray; uses the power telescopic member in the clamping jaw mechanism to drive the clamping jaws at both ends to move, adjusts the opening distance between the clamping jaws at both ends to a suitable value, and reaches the specified insertion position, so that the end of the clamping jaw far from the power telescopic member is located outside the module; uses the power member to drive the clamping jaw mechanism to move to the specified clamping position; finally, uses the power telescopic member to drive the clamping jaws at both ends to move, so that each clamping jaw at both ends extends into the bottom of the corresponding battery cell in the module, performs a bottom-supporting action on each battery cell, and clamps the module, which can effectively prevent the long module or multi-column module from having displacement or falling in the vertical direction, and has higher safety performance.

[0040] The following will describe the application principle of the present utility model in detail with reference to the accompanying drawings. Embodiment
[0041] As Figure 1 shown, in this embodiment, a module anti-drop clamping mechanism is provided, including: a tray 3, a power member 1, and a jaw mechanism 2;
[0042] The tray 3 is used to place the module; in the specific implementation process, the module can be a long battery cell module or a multi-column module;
[0043] The jaw mechanism 2 is located above the tray 3 and includes a mounting plate 21 connected to the power member 1. A power telescopic member 22 is provided on the mounting plate 21; a plurality of jaws 23 are provided at both ends of the power telescopic member 22; the jaw mechanism 2 is used to cooperate with the power member 1 so that the jaws 23 at both ends thereof extend into the bottom of the corresponding battery cell 4 in the module. Only one jaw 23 supports the bottom of one battery cell 4, and the module is clamped. In the specific implementation process, the mounting plate 21 of the jaw mechanism 2 is fixedly or movably connected to the power member 1.
[0044] For the above technical solution, the module is placed on the tray 3; the power telescopic member 22 in the jaw mechanism 2 is used to drive the jaws 23 at both ends thereof to move, adjust the opening distance between the jaws 23 at both ends to a suitable position, reach the specified insertion position, so that the end of the jaw 23 far from the power telescopic member 22 is located outside the module; the power member 1 is used to drive the jaw mechanism 2 to move to the specified clamping position; finally, the power telescopic member 22 is used to drive the jaws 23 at both ends thereof to move, so that the jaws 23 at both ends thereof extend into the bottom of the corresponding battery cell 4 in the module, perform a bottom-supporting action on each battery cell 4, and clamp the module. For details, see Figure 4 , which can effectively prevent the long module or multi-column module from having displacement or falling in the vertical direction, and has higher safety performance.
[0045] In a specific implementation manner of this embodiment, a plurality of notches 33 are provided on both opposite sides of the tray 3 along the arrangement direction of the battery cells 4 in the module. For the convenience of manufacturing and to balance the force on each jaw, the notches 33 on both sides are arranged staggeredly, the jaws 23 at both ends of the power telescopic member 22 are arranged staggeredly, and the notches 33 are used for the jaws 23 to extend into the bottom of the corresponding battery cell 4. In the specific implementation process, as Figure 3As shown, the tray 3 includes a side plate 31 and a bottom plate 32; the notch 33 can be formed in the following way. Specifically: the two side walls of the tray 3 along the opposite sides in the arrangement direction of the battery cells 4 in the module are hollowed out, and thus a number of notches 33 are obtained. Preferably, the distance between adjacent notches 33 corresponds to the distance between adjacent battery cells 4, and also corresponds to the distance between adjacent jaws 23, which can ensure that the jaws 23 can smoothly enter or withdraw from the corresponding notches 33.
[0046] Since during the production of the battery cells 4, adjacent battery cells 4 are usually pasted together by gluing. Therefore, in the above technical solution, by arranging staggered notches 33 on both sides of the tray 3, one jaw 23 can support the bottom of one battery cell 4 in the module, greatly reducing the number of jaws 23. On the premise of effectively preventing the long module or multi-column module from having displacement or falling in the vertical direction, the production cost of the anti-falling clamping mechanism of the entire module is reduced.
[0047] In a specific implementation manner of this embodiment, as Figure 2 shown, both ends of the power telescopic member 22 are provided with connecting plates 25, and the connecting plates 25 are connected to the jaws 23; each jaw 23 is provided with a filling block 24. When the jaw 23 extends into the corresponding notch 33, there is a clearance fit between the filling block 24 and the notch 33, and it contacts the corresponding battery cell 4. In the specific implementation process, the connecting plate 25 is perpendicular to the jaw 23, and the jaw 23 is linear. The connecting plate 23 is connected to the power telescopic member 22 through an adapter, and the connection between it and the adapter can be a bolt connection, which is convenient for disassembly and maintenance.
[0048] In the above technical solution, when each jaw 23 extends into the bottom of the corresponding battery cell 4 in the module, the filling block 24 is located between the connecting plate 25 and the module, and is in close contact with the side walls of the connecting plate 25 and the module respectively, and can greatly improve the clamping force on the module.
[0049] In a specific implementation manner of this embodiment, the ratio of the height of the filling block 24 to the height of the corresponding battery cell 4 in the module is greater than a set threshold. For example: when the jaw 23 extends into the bottom of the corresponding battery cell 4 in the module, the top of the filling block 24 is higher than the top of the battery cell 4, or the top of the filling block 24 is flush with the top of the battery cell 4.
[0050] In the above technical solution, by setting the height of the filling block 24, the contact area between the filling block 24 and the corresponding battery cell 4 is increased, and finally the clamping force on the module is improved, thereby reducing the requirement for the length of the jaw 23.
[0051] In a specific implementation manner of this embodiment, the distance between adjacent jaws 23 is equal to the distance between adjacent notches 33.
[0052] In the above technical solution, after each gripper 23 extends into the bottom of the corresponding battery cell 4 in the module, there is a clearance fit between the gripper 23 and the corresponding notch 33, which is beneficial for the insertion or extraction of the gripper 23 and increases the area for supporting the battery cell 4 at the bottom.
[0053] In a specific implementation manner of this embodiment, the total number of grippers 23 at both ends of the power telescopic member 22 is equal to the number of battery cells 4 in the module.
[0054] In the above technical solution, during the production of the battery cell 4, the adjacent battery cells 4 are usually pasted together by means of adhesive tape. Therefore, in the above technical solution, by arranging the notches 33 in a staggered manner on both sides of the tray 3, one gripper 23 can support one battery cell 4 in the module. While greatly reducing the number of grippers 23, it can effectively prevent the long module or multi-column module from having displacement or falling in the vertical direction.
[0055] In a specific implementation manner of this embodiment, the power telescopic member 22 is a cylinder. In other implementation manners of the present invention, the power telescopic member 22 can also be selected from components other than the cylinder that can achieve the opposite movement of the grippers 23 at both ends thereof, and can be specifically selected according to the actual situation.
[0056] In the above technical solution, the cylinder can be directly purchased from the market, and the cost is low.
[0057] In a specific implementation manner of this embodiment, the number of cylinders is greater than or equal to 1. When the number of cylinders is greater than 1, the cylinders are in a parallel relationship.
[0058] In the above technical solution, it is possible to determine the number of cylinders to be activated according to the actual length of the module, so as to reduce the overall power consumption of the anti-falling clamping mechanism of the module and save electric energy.
[0059] In a specific implementation manner of this embodiment, the power member 1 includes an X-axis linear drive unit, a Y-axis linear drive unit, a Z-axis linear drive unit, and a rotation unit; the X-axis linear drive unit, the Y-axis linear drive unit, and the Z-axis linear drive unit are connected to each other to form a motion module that can move in the X, Y, and Z axis directions, and the rotation unit is connected to the motion module to drive the motion module to rotate. The specific structures of the X-axis linear drive unit, the Y-axis linear drive unit, the Z-axis linear drive unit, and the rotation unit are all prior arts, so they will not be described in detail in the present invention, and the X-axis linear drive unit, the Y-axis linear drive unit, the Z-axis linear drive unit, and the rotation unit can be directly purchased from the market.
[0060] In the above technical solution, through the design of the power component 1, the gripper mechanism 2 can move and rotate in the X, Y, and Z directions, so as to complete the clamping and transfer process of the module with multiple degrees of freedom.
[0061] The following will Figures 1 to 5 describe in detail the working process of a module anti-drop gripper mechanism in this embodiment:
[0062] First, after the tray 3 is transported to the designated position along the logistics line 5, the tray 3 is repositioned. The power component 1 drives the gripper mechanism 2 to reach the designated gripping position. At the same time, the power telescopic member 22 (i.e., the cylinder) in the gripper mechanism 2 acts to adjust the opening distance between the two ends of the gripper 23 to an appropriate value and reach the designated insertion position.
[0063] Then, the power telescopic member 21 in the gripper mechanism 2 reduces its stroke to insert the gripper 23 into the notch 33 on the tray 3 according to the spacing between adjacent battery cells 4, reaching the bottom 41 of each battery cell. Specifically, refer to Figure 5 to perform a bottom-supporting action on each battery cell 4. At this time, the battery cell 4 does not move in the vertical direction. This action aims to first perform a bottom-supporting action on the long battery cell module or multi-column module to protect the module, and then start the power telescopic member 22 to use the gripper mechanism 2 to grip the battery cell 4. Compared with the traditional method of first grasping and then bottom-supporting, the method of gripping the battery cell module in the present invention greatly increases the safety and reliability of grasping and can prevent the module from falling during the process of lifting the module and then bottom-supporting.
[0064] Finally, by cooperating the power component 1 with the gripper mechanism 2, the long module or multi-column module is grabbed from the logistics line 5 to complete the transfer of the long module or multi-column module. On the logistics line 5 where the long module or multi-column module is placed, the same type of tray 3 is also used, and the form is similar to the grasping process of the long module or multi-column module, which can ensure the whole-process transfer of the long battery cell module or multi-column module. First, use the gripper 23 to bottom-support, and then grab the long battery cell module or multi-column module, which greatly reduces the risk of the module falling during the transfer without bottom-supporting. Embodiment
[0065] Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is that connecting rods are provided at both ends of the power telescopic member 22, the connecting rods are connected to the gripper 23, and the gripper 23 is L-shaped.
[0066] In the above technical solution, the L-shaped gripper is used to simultaneously perform bottom-supporting for the battery cells 4 in the module and closely fit the side wall of the battery cell 4, so as to improve the clamping force on the module.
