Description

Technical Field

[0001] The present invention relates to the technical field of lithium batteries, and in particular to a mounting device for lithium batteries. Background Art

[0002] Lithium batteries have the advantages of high energy, long service life, high rated voltage, high power tolerance, very low self-discharge rate, and strong adaptability to high and low temperatures. They are one of the most widely used batteries. During the installation of lithium batteries, the arrangement and assembly of the battery cells is of utmost importance. For the convenience of packaging, the battery cells are often stacked on the battery tray or in the packaging box with the positive pole facing up. During the assembly of the battery cells, after the staff takes out the battery cells stored in the battery tray, they need to arrange multiple rows of battery cells in the form of alternating positive and negative in the mounting frame for spot welding connection.

[0003] A battery cell mounting rack is disclosed in the patent document with the authorization announcement number CN220138586U, comprising: a base, the base comprising a substrate and side panels; the side panels are connected to the substrate and are arranged oppositely on both sides of the substrate; a slot is arranged on the substrate; a top seat, the top seat comprising a top plate and a vertical plate; the vertical plate is connected to the top plate and is arranged oppositely on both sides of the top plate, the vertical plate and the side plates are respectively extended from the top plate and the substrate towards each other; the top plate is provided with mounting grooves, the mounting grooves are configured to be arranged in pairs corresponding to the slots one by one, so as to be used for power supply The two ends of the core are inserted and fixed; an anti-foolproof component, which is arranged in one of the paired slots and the mounting slots, and the anti-foolproof component is inserted into the groove of the positive cap of the battery cell in a convex shape to control the installation direction of the battery cell. By arranging a convex anti-foolproof component in one of the paired slots and the mounting slots, when the battery cell is reversed, the anti-foolproof component cannot be inserted into the groove of the positive cap, thereby making it impossible to close the base and the top seat, thereby realizing physical anti-reverse installation, with a simple structure and low application cost, and no false detection or missed detection, thereby avoiding product damage and scrapping and ensuring the product yield.

[0004] However, the solution still has the following problems: although the anti-foolproof component can be used to prevent the staff from installing the battery cells upside down during placement, the battery cell assembly requires the staff to take the battery cells out of the battery tray and place them one by one in the mounting rack, and the amount of battery cells used in lithium batteries is often large, and some battery cells need to be turned over during placement, which results in high labor intensity and low assembly efficiency for the staff, especially after the anti-foolproof component detects that the battery cell is placed upside down, the staff needs to spend time picking up the battery cell and placing it again, which further slows down the assembly rhythm of the battery cell and affects the installation efficiency of the lithium battery. Summary of the invention

[0005] The present invention provides an installation device for lithium batteries, aiming to solve the problem in the related art that workers need to take out battery cells from a battery cell tray and place them one by one in an installation frame, resulting in high labor intensity and low assembly efficiency.

[0006] The mounting device for lithium batteries of the present invention comprises a mounting frame, which is composed of an upper support and a lower support, wherein multiple rows of positive electrode slots and negative electrode slots are provided on the upper support and the lower support, and the positive electrode slots and the negative electrode slots are staggered, and a positioning cylinder connected to the positive electrode slots is fixedly installed on the upper support and the lower support, and a grasping mechanism is provided on one side of the positioning cylinder for grasping and fixing the battery cell inserted into the positioning cylinder, and a through groove is provided on the side wall of the positioning cylinder;

The clamping block is arranged on the wedge block and can slide in the through groove as the wedge block moves to fix or release the battery cell.

[0008] The effect is that after the upper support and the lower support are buckled onto the battery cell tray, the grabbing mechanism can grab the battery cells inserted into the positive electrode slots of the upper support and the lower support, and then buckle the upper support and the lower support up and down to complement the battery cells, and quickly complete the alternating arrangement of the battery cells in the forward and reverse directions, eliminating the trouble of the staff taking and placing the battery cells one by one, reducing the labor intensity of the staff and improving the efficiency of battery cell assembly, and can effectively reduce the probability of errors in the placement of the battery cells.

[0009] Preferably, the side of the wedge block close to the positioning cylinder is an inclined surface, and a sliding groove is opened on the inclined surface of the wedge block along its inclination direction. A connecting rod is fixedly mounted on the block, and the end of the connecting rod away from the block is slidably assembled in the sliding groove. The effect is that the position of the connecting rod in the sliding groove is changed, thereby driving the block to slide in the through groove.

[0010] Preferably, the gripping mechanism further comprises a support plate, which is slidably mounted on the outside of the positioning tube, and a driving assembly is provided on one side of the support plate for pushing the support plate to slide up and down outside the positioning tube.

The threaded column is threadedly connected in the threaded hole. The effect is that the threaded column is rotated to move in the threaded hole, so that the threaded column brings the support plate up and down outside the positioning cylinder, so that the wedge block can drive the card block to move laterally.

[0012] Preferably, a knob is fixedly mounted on the threaded column, and a stepped groove matching the knob is provided on the outer side of the threaded hole.

[0013] Preferably, a reset mechanism is provided on one side of the connecting rod for resetting the card block to release the fixation of the battery cell. The reset mechanism includes an L-shaped plate and an elastic member. The bottom end of the L-shaped plate is fixedly mounted on the side wall of the positioning cylinder. The elastic member is arranged between the L-shaped plate and the card block. The effect is that a pulling force is applied to the L-shaped plate by the elastic member, so that when the support plate is reset, it is easy to pull the card block to reset and release the fixation of the battery cell.

[0014] Preferably, a transverse groove is provided at the bottom of the connecting rod, and the top end of the L-shaped plate extends to one side of the through groove and is slidably assembled inside the transverse groove.

[0015] Preferably, guide columns are vertically installed on the upper support and the lower support, and the guide columns on the upper support and the lower support correspond to each other up and down, one end of the guide column is provided with a vertical groove along its axial direction, and the other end of the guide column is provided with a threaded groove along its axial direction, and the vertical groove and the threaded groove are connected to each other.

[0016] Preferably, an installation shaft is provided in the vertical groove on the upper support, and a screw rod is fixedly installed on the end of the installation shaft. The screw rod is threadedly connected in the threaded groove, and the bottom end of the screw rod extends to the outside of the guide column. The effect is that by rotating the screw rod into the threaded groove of the guide column on the lower support, the upper support and the lower support can be quickly fixed to facilitate spot welding operations on the battery cells.

[0017] Preferably, the outside of the installation shaft is provided with anti-slip grooves, and the top end of the installation shaft is provided with a wrench groove.

[0018] Beneficial effects:

[0019] When the present invention is in use, the upper support and the lower support fix the positive end of the battery cell, so as to conveniently and efficiently complete the grasping and fixing of the battery cells in the same row on the battery cell tray, and with the buckling between the upper support and the lower support, the battery cells are automatically arranged in a forward and reverse alternating manner, eliminating the trouble of staff members taking and placing the battery cells one by one. While reducing the labor intensity of the staff and improving the efficiency of battery cell assembly, it can effectively reduce the probability of errors in the placement and arrangement of the battery cells, and improve the qualified rate of lithium batteries after installation.

[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figures 1 to 8 As shown, the installation device for lithium batteries of the present invention includes a mounting frame 10, on which a gripping mechanism 20 and a driving assembly 30 are provided. The gripping mechanism 20 can be driven by the driving assembly 30 to operate to grip and fix the battery cell. A reset mechanism 40 is provided on one side of the gripping mechanism 20 to reset the gripping mechanism 20 to release the fixation of the battery cell.

[0032] refer to Figure 1The mounting frame 10 includes an upper support 11 and a lower support 12, and multiple rows of positive electrode slots 13 and negative electrode slots 14 are provided on the upper support 11 and the lower support 12, and the positive electrode slots 13 and the negative electrode slots 14 are staggered. The positive electrode slots 13 in the upper support 11 correspond to the negative electrode slots 14 in the lower support 12 up and down, and the negative electrode slots 14 in the upper support 11 correspond to the positive electrode slots 13 in the lower support 12 up and down. Then, multiple rows of battery cells can be arranged alternately in forward and reverse directions and installed in the mounting frame 10, and the spacing between adjacent positive electrode slots 13 and negative electrode slots 14 is adapted to the spacing between adjacent battery cells in the battery cell tray, so that after the upper support 11 or the lower support 12 is buckled on the battery cell tray, the battery cells can be accurately inserted into the positive electrode slots 13 and the negative electrode slots 14.

[0033] refer to Figure 1-Figure 3 A positioning cylinder 15 connected to the positive electrode slot 13 is fixedly installed on the upper support 11 and the lower support 12. A through groove 151 is opened on the side wall of the positioning cylinder 15. A sealing ring 152 is arranged on one side of the through groove 151 in the positioning cylinder 15, which can close the through groove 151 so that the grasping mechanism 20 will not directly clamp the battery cell, but clamp and fix the battery cell by squeezing the sealing ring 152, thereby avoiding direct force on the battery cell and causing damage.

[0034] refer to Figure 1-Figure 5 , threaded holes 16 are provided on the upper support 11 and the lower support 12 to facilitate the installation of the driving assembly 30 , and stepped grooves 17 are provided on the outer sides of the threaded holes 16 to facilitate the storage of the driving assembly 30 .

[0035] refer to Figure 1 and Figure 7 A guide column 18 is vertically mounted on both the upper support 11 and the lower support 12, and the guide columns 18 on the upper support 11 and the lower support 12 correspond to each other in the vertical direction. A vertical groove 181 is opened at one end of the guide column 18 along its axial direction, and a thread groove 182 is opened at the other end of the guide column 18 along its axial direction, and the vertical groove 181 and the thread groove 182 are connected to each other. A mounting shaft 183 is arranged in the vertical groove 181 on the upper support 11, and a screw rod 184 is fixedly mounted at the end of the mounting shaft 183. The screw rod 1 84 is threadedly connected in the thread groove 182, and the bottom end of the screw rod 184 extends to the outside of the guide column 18, and can make the screw rod 184 rise and fall along the thread groove 182 as the installation shaft 183 rotates in the vertical groove 181. When the upper support 11 and the lower support 12 are buckled up and down, the bottom end of the screw rod 184 can be screwed into the thread groove 182 of the guide column 18 in the lower support 12 during the descent, and then the upper support 11 and the lower support 12 are fixed to prevent the mounting frame 10 from spreading, so as to facilitate the subsequent spot welding operation of the battery cell.

[0036] The outside of the installation shaft 183 is provided with anti-slip grooves to facilitate the staff to rotate the installation shaft 183, and the top of the installation shaft 183 is provided with a wrench groove 185, so that the staff can use a wrench to insert the wrench groove 185 and completely screw the installation shaft 183 into the vertical groove 181 to avoid the installation shaft 183 protruding in the mounting frame 10 and affecting the subsequent assembly of the lithium battery.

[0037] refer to Figure 1 , Figure 4 and Figure 8 The grabbing mechanism 20 includes a support plate 21, a wedge block 22 and a clamping block 23. The support plate 21 is arranged outside the positioning cylinder 15 and can slide up and down relative to the positioning cylinder 15. The support plate 21 is slidably connected to the outside of the guide column 18. The wedge block 22 is fixedly installed on the support plate 21. The side of the wedge block 22 close to the positioning cylinder 15 is an inclined surface. The clamping block 23 is slidably assembled inside the through groove 151 and can slide in the through groove 151 as the wedge block 22 is raised and lowered, so as to clamp and fix the battery cell. A through hole adapted to the negative electrode slot 14 is also provided on the support plate 21, so that the battery cell can pass through the support plate 21 and be inserted into the negative electrode slot 14.

[0038] refer to Figure 6 A slide groove 221 is provided on the inclined surface of the wedge block 22 along its inclination direction, a connecting rod 231 is fixedly installed on the clamping block 23, and the end of the connecting rod 231 away from the clamping block 23 is slidably assembled in the slide groove 221, so that the wedge block 22 can push the connecting rod 231 to slide in the slide groove 221 during movement, and then drive the clamping block 23 to move to complete the clamping and fixing of the battery cell.

[0039] refer to Figure 1 , Figure 3 and Figure 5 The driving assembly 30 includes a rotating seat 31 and a threaded column 32. The rotating seat 31 is rotatably assembled on the support plate 21. The end of the threaded column 32 is coaxially fixed to the rotating seat 31, and the threaded column 32 is threadedly connected to the threaded hole 16. The threaded column 32 is rotated and lifted in the threaded hole 16 to drive the support plate 21 on one side of the corresponding upper support 11 or lower support 12 to move, and then the clamping block 23 clamps and fixes the battery cell. A knob 321 is fixedly installed on the threaded column 32, and the knob 321 is adapted to the size of the stepped groove 17. The knob 321 can facilitate the rotation of the threaded column 32, and after the battery cell is grasped and fixed as the threaded column 32 moves, the knob 321 can be stored in the stepped groove 17 to avoid increasing the volume of the equipment, so as to facilitate the subsequent assembly process.

[0040] refer to Figure 6The reset mechanism 40 includes an L-shaped plate 41 and an elastic member 42. The bottom end of the L-shaped plate 41 is fixedly mounted on the side wall of the positioning tube 15. A transverse groove 232 is provided at the bottom of the connecting rod 231. The top end of the L-shaped plate 41 extends to one side of the through groove 151 and is slidably assembled inside the transverse groove 232. The elastic member 42 is arranged between the L-shaped plate 41 and the block 23, and can be stretched when the block 23 moves to position the battery cell, and then exert a backward pulling force on the block 23. When the wedge block 22 moves and resets, the block 23 is pulled to move and reset to release the positioning of the battery cell. In this solution, the elastic member 42 is specifically an elastic rope, and in other solutions, the elastic member 42 can also be a spring.

[0041] Working principle: first, buckle the lower support 12 onto the top of the battery tray, so that the upper ends of the multiple rows of battery cells (i.e., the positive ends of the battery cells) are respectively inserted into the corresponding positive electrode slots 13 and negative electrode slots 14 in the lower support 12, and then rotate the threaded column 32 on the lower support 12 to make it descend along the threaded hole 16, push the support plate 21 with the wedge block 22 to descend relative to the positioning cylinder 15, push the block 23 to slide along the through groove 151 toward the central axis of the positioning cylinder 15, and then squeeze the sealing ring 152 to grab and fix the battery cell passing through the positioning cylinder 15, and then move the lower support 12 upward to drive the battery cell fixed in the positive electrode slot 13 to move and pull it out of the battery tray. The battery cell inserted into the negative electrode slot 14 is not fixed, so it still stays in the battery tray, so as to quickly complete the filling of the battery cell in the lower support 12;

[0042] After the lower support 12 is filled with battery cells, the upper support 11 is buckled onto the battery cell tray, so that the upper ends of the multiple rows of battery cells (i.e., the positive ends of the battery cells) are respectively inserted into the corresponding positive electrode slots 13 and negative electrode slots 14 in the upper support 11, and then the threaded column 32 on the upper support 11 is rotated to push the support plate 21 with the wedge block 22 to descend relative to the positioning cylinder 15, grab and fix the battery cells inserted into the positive electrode slots 13, and quickly complete the filling of the battery cells in the upper support 11;

[0043] Finally, the upper support 11 and the lower support 12 are buckled together, so that the negative end of the battery cell in the upper support 11 is inserted into the negative electrode slot 14 on the lower support 12, and the negative end of the battery cell in the lower support 12 is inserted into the negative electrode slot 14 on the upper support 11, and then the installation shaft 183 in the guide column 18 on the upper support 11 is rotated to make the screw rod 184 rotate and descend in the threaded groove 182, and the screw rod 184 is screwed into the threaded groove 182 in the guide column 18 on the lower support 12 during the descent, so as to complete the fixation between the upper support 11 and the lower support 12, so that the upper support 11 and the lower support 12 are not easily separated, and then the upper and lower ends of the battery cell are limited and fixed to complete the assembly of the battery cell.

[0044] In the present invention, the positive end of the battery cell is fixed by the upper support 11 and the lower support 12, so that the battery cells in the same row on the battery cell tray are grabbed and fixed conveniently and efficiently, and with the buckling between the upper support 11 and the lower support 12, the battery cells are automatically arranged in the forward and reverse directions alternately, which saves the trouble of the staff to take and place the battery cells one by one. While reducing the labor intensity of the staff and improving the efficiency of battery cell assembly, it can effectively reduce the probability of errors in the placement of the battery cells and improve the qualified rate of lithium batteries after installation.

[0045] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
