Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of pole group installation, and particularly relates to a storage battery pole group plug side plate compacting device. BACKGROUND

[0002] With the rapid development of the new energy automobile industry, unprecedented high requirements are put forward for the performance, consistency and safety reliability of the core component, i.e. the power battery. In the manufacturing of lead-acid or specific configuration lithium ion power batteries, accurately and firmly pressing the pole group and the pole group plug side plate into the multiple parallel narrow installation slots in the battery shell is a key core process which determines the energy density, cycle life and safety of the battery. The new energy automobile battery is usually designed with multiple high-precision installation slots, and each slot needs to tightly accommodate the compressed pole group and the plug side plates on both sides thereof.

[0003] In the prior art, a common process method is to use step-by-step operation: first, the pole group (usually containing a separator) is manually or with the aid of a simple positioning tool placed into the installation slot of the battery shell; then, the two pole group plug side plates are respectively pressed into the installation slot from both sides and tightly adhere to both ends of the pole group, such as a storage battery pole group plug side plate compacting device disclosed in CN222867757U.

[0004] However, the above prior art has significant disadvantages: first, the step-by-step operation is inefficient, and the first pole group and the second plug side plate need to be positioned and operated twice, which prolongs the production cycle and is difficult to meet the needs of large-scale production of new energy automobiles. Manual operation cannot guarantee that multiple plug side plates and pole groups are accurately positioned and uniformly stressed in multiple installation slots at the same time, which may cause the pole group to be skewed in the slot, the plug side plate to be pressed to different depths, and even damage the pole plate or the separator, thereby causing safety hazards. SUMMARY

[0005] The purpose of the embodiment of the application is to provide a storage battery pole group plug side plate compacting device, which aims to solve the problems proposed in the background art.

[0006] This invention is implemented as follows: a battery terminal block edge compaction device includes a frame and further includes: a guide groove first disposed on the frame, wherein five guide blocks are sequentially disposed along the length of the guide groove first, the guide block near one end of the guide groove first is fixed to the frame, and the other four guide blocks are slidably connected within the guide groove first; a telescopic component second is fixed to the side wall of the frame, and the telescopic end of the telescopic component second is connected to the guide block near the other end of the guide groove first; each pair of adjacent guide blocks is connected by a linear coupling assembly, the linear coupling assembly including a connecting rod, one end of which is fixed with a sliding block. The other end of the connecting rod is fixed to one end of one of the two adjacent guide blocks. One end of the other guide block is provided with a sliding groove, and the sliding block is slidably connected in the sliding groove. A pressing plate is fixed to the top of the two guide blocks near one end of the guide groove, and two pressing plates are fixed to the top of the other three guide blocks. The two pressing plates at the top of the other three guide blocks form a clearance space, which is used to avoid the partition. The two pressing plates that are close to each other on each pair of adjacent guide blocks form a pressing space, which is used to press the electrode group edge plate and the electrode group.

[0007] A further technical solution is that the bottom of the fixed guide block and the three middle guide blocks are all fixed with concave fixing frames, and the bottom of the four concave fixing frames are all fixed with telescopic components. The telescopic ends of the four telescopic components extend upward through the concave fixing frames and are connected to the top material frame. The four top material frames are slidably connected to the fixed guide block and the three middle guide blocks respectively.

[0008] In a further technical solution, a pressing mechanism is provided on the top of the frame, which is used to press down on the battery casing.

[0009] In a further technical solution, the pressing mechanism includes a guide frame fixed to the top of the frame, a telescopic member three fixed to the top of the guide frame, the telescopic end of the telescopic member three extending downward through the guide frame and connected to a pressing plate, and the pressing plate slidingly connected vertically to the guide frame.

[0010] A further technical solution includes an auxiliary support mechanism on the guide frame, comprising a sliding frame vertically slidably connected to the guide frame, the sliding frame being located below the pressing plate, and guide grooves 2 on two opposing inner walls of the sliding frame, with three I-shaped support slide rods 1 and one I-shaped support slide rod 2 slidably connected sequentially within the guide grooves 2. A telescopic component 4 is fixedly mounted on the side wall of the sliding frame, the telescopic end of the telescopic component 4 penetrating the side wall of the sliding frame and connecting to the I-shaped support slide rod 2. A support rod is fixedly mounted on the inner wall of the sliding frame away from the telescopic component 4. A telescopic component 5 is fixedly mounted at the bottom of the frame, the telescopic end of the telescopic component 5 penetrating upward through the frame and connecting to the sliding frame.

[0011] Further technical solutions, the support rod top is fixed with a concave alignment plate, and the H-shaped support sliding rod is fixed with a movable alignment plate at two top parts.

[0012] Further technical solutions, the rear side alignment plate is fixed on the rear side inner wall of the sliding frame, and the front side alignment plate is fixed on the front side inner wall of the sliding frame, and the distance between the rear side alignment plate and the front side alignment plate is equal to the length of the long side of the installation groove.

[0013] Compared with the prior art, the beneficial effects of the present application are:

[0014] 1. By driving five linkage guide blocks through the telescopic part two, multiple groups of extrusion plates are synchronized to shrink, and the compaction of the pole group blocking plate and the pole group in multiple installation grooves is completed at one time, which greatly shortens the production rhythm and meets the demand of large-scale manufacturing;

[0015] 2. The extrusion space of the extrusion plate is matched with the pole group assembly structure, and the H-shaped support sliding rod (driven by the telescopic part four) and the alignment plate (concave alignment plate, movable alignment plate, etc.) of the auxiliary support mechanism are combined to ensure that the assembly is not skewed and the pressing depth is consistent during the compaction process;

[0016] 3. The width design of the jacking frame (greater than the inner side distance of the pole group blocking plate and less than the outer side distance) avoids damage to the pole group under stress during jacking. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0028] The specific implementation of the present application is described in detail below in combination with specific examples.

[0029] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , and Figure 9As shown, the battery pole group plug edge plate compaction device provided by the embodiment of the application comprises a rack 101, further comprises a guide groove one 102 arranged on the rack 101, five guide blocks 103 are sequentially arranged in the guide groove one 102 along the length direction of the guide groove one 102, the guide block 103 close to one end of the guide groove one 102 is fixed on the rack 101, and the remaining four guide blocks 103 are all slidingly connected in the guide groove one 102, a telescopic part two 108 is fixed on the side wall of the rack 101, and the telescopic end of the telescopic part two 108 is connected with the guide block 103 close to the other end of the guide groove one 102; every two adjacent guide blocks 103 are connected through a linear coupling assembly 3, the linear coupling assembly 3 comprises a connecting rod 301, one end of the connecting rod 301 is fixedly provided with a sliding block 302, the other end of the connecting rod 301 is fixedly arranged on one end of one of the two adjacent guide blocks 103, one end of the other guide block 103 of the two adjacent guide blocks 103 is provided with a sliding groove 303, and the sliding block 302 is slidingly connected in the sliding groove 303; one extrusion plate 104 is fixedly arranged on the top of the two guide blocks 103 close to the two ends of the guide groove one 102, two extrusion plates 104 are fixedly arranged on the top of the remaining three guide blocks 103, the two extrusion plates 104 on the top of the remaining three guide blocks 103 all form an avoiding space, the avoiding space is used for avoiding the baffle 61, and the extrusion space is formed between the two extrusion plates 104 on the two adjacent guide blocks 103 and close to each other, and the extrusion space is used for extruding the pole group plug edge plate and the pole group.

[0030] In the embodiment of the application, the telescopic part one 107 and the telescopic part two 108 can adopt air cylinders, electric telescopic rods and hydraulic cylinders and the like, in use, the telescopic part two 108 is in a retracted state, the five guide blocks 103 are away from each other, and the extrusion space is in an open state (as shown in the state of the five guide blocks 103 in Figure 1 、 Figure 3 and Figure 4 ), that is, the distance between the two extrusion plates 104 on the two adjacent guide blocks 103 and close to each other is maximum, the pole group plug edge plate and the pole group can be conveniently placed in the extrusion space, the telescopic part one 107 is in a retracted state, the material pushing frame 106 is located in the extrusion plate 104, and the top of the extrusion plate 104 is horizontal.

[0031] Two pole group plug-in side plates are placed in the extrusion space, and a pole group is placed between the two pole group plug-in side plates. After the pole group plug-in side plates and the pole group are placed in the four extrusion spaces, the telescopic member two 108 is elongated, and the telescopic member two 108 drives the guide block 103 close to the other end of the guide groove one 102 to move. This guide block 103 sequentially pushes the remaining four guide blocks 103 to move, until the five guide blocks 103 are sequentially connected at the head and tail (such as Figure 6 , the state of the five guide blocks 103). At this time, every two adjacent guide blocks 103 on the two extrusion plates 104 close to each other extrude the pole group plug-in side plates and the pole group in the opposite extrusion space, thereby reducing the thickness of the pole group plug-in side plates and the pole group. Then, the battery shell 6 is inverted and placed above the plurality of extrusion plates 104, so that the pole group plug-in side plates and the pole group in the four extrusion spaces, and the two extrusion plates 104 adjacent to the four pole group plug-in side plates and the pole group are located directly below the four mounting grooves 62 of the battery shell 6. Then, the battery shell 6 is pressed downward, and the two extrusion plates 104, the two pole group plug-in side plates and the pole group in the mounting groove 62 are pressed into the four mounting grooves 62 of the battery shell 6. At this time, the mounting groove 62 has two extrusion plates 104, two pole group plug-in side plates and a pole group. The telescopic member one 107 is elongated, and the telescopic member one 107 drives the material lifting frame 106 to move upward. At this time, the width of the material lifting frame 106 is less than the distance between the two outer sides of the pole group plug-in side plates, and the width of the material lifting frame 106 is greater than the distance between the two inner sides of the pole group plug-in side plates. Therefore, the material lifting frame 106 acts on the two pole group plug-in side plates when it moves upward, so as to avoid excessive force on the pole group. At this time, the pole group plug-in side plates, the battery shell 6 and the pole group move upward. Since the extrusion plate 104 cannot move upward, the extrusion plate 104 is separated from the battery shell 6. The pole group naturally expands, and the extrusion plate 104 contacts the side wall of the mounting groove 62. Through the expansion force of the pole group, the pole group and the pole group plug-in side plate are fixed in the mounting groove 62. At this time, the material lifting frame 106 supports the pole group plug-in side plates, the battery shell 6 and the pole group, which facilitates the removal of the battery shell 6 with the installed pole group and the pole group plug-in side plate.

[0032] As shown in Figure 1 and Figure 2 , as a preferred embodiment of the present application, the rack 101 is provided with a pressing mechanism 2 at the top, which is used to press the battery shell 6 downward. The pressing mechanism 2 includes a guide frame 201 fixed on the top of the rack 101, a telescopic member three 202 fixed on the top of the guide frame 201, and a pressing plate 203 connected to the telescopic end of the telescopic member three 202 and penetrating downward through the guide frame 201.

[0033] In this embodiment of the invention, the telescopic component 202 can be a cylinder, an electric telescopic rod, or a hydraulic cylinder. In the initial state, the telescopic component 202 is in a retracted state, and the space between the top of the pressing plate 203 and the extrusion plate 104 is greater than the height of the battery housing 6. The battery housing 6 is placed upside down on top of multiple extrusion plates 104, so that the electrode group edge plates and electrode groups in the four extrusion spaces, as well as the two adjacent extrusion plates 104 of the four electrode group edge plates and electrode groups, are respectively located directly below the four mounting slots 62 of the battery housing 6. Then, the telescopic component 202 extends, and under the guidance of the guide frame 201, the telescopic component 202 drives the pressing plate 203 to move downward. The pressing plate 203 presses down on the battery housing 6, pressing the four electrode group edge plates and electrode groups, as well as the two adjacent extrusion plates 104 of the four electrode group edge plates and electrode groups, into the four mounting slots 62 of the battery housing 6. Then, the telescopic component 202 retracts, and the telescopic component 202 drives the pressing plate 203 to move upward and reset.

[0034] The extrusion plate 104 is a thin plate. When the extrusion plate 104 compresses the electrode group edge plate and the electrode group, the top of the extrusion plate 104 is not supported. After long-term use, the extrusion plate 104 is prone to deformation, causing the extrusion plates 104 on both sides of the extrusion space to form a flared mouth, which in turn affects the compression effect of the electrode group edge plate and the electrode group, making it impossible for the electrode group edge plate and the electrode group to be pressed into the mounting groove 62.

[0035] like Figure 1 , Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, in a preferred embodiment of the present invention, an auxiliary support mechanism 4 is provided on the guide frame 201. The auxiliary support mechanism 4 includes a sliding frame 401 vertically slidably connected to the guide frame 201. The sliding frame 401 is located below the press-in plate 203. Guide grooves 402 are provided on two opposing inner walls of the sliding frame 401. Three I-shaped support slide rods 404 and one I-shaped support slide rod 405 are slidably connected in sequence in the guide grooves 402. A telescopic member 406 is fixed on the side wall of the sliding frame 401. The telescopic end of the telescopic member 406 penetrates the side wall of the sliding frame 401 and is connected to the I-shaped support slide rod 405. A support rod 403 is fixed on the inner wall of the sliding frame 401 away from the telescopic member 406. A telescopic member 407 is fixed at the bottom of the frame 101. The telescopic end of the telescopic member 407 penetrates the frame 101 upward and is connected to the sliding frame 401.

[0036] In this embodiment of the invention, telescopic components 406 and 407 can be made of cylinders, electric telescopic rods and hydraulic cylinders, etc. The three I-shaped support slide rods 404 are respectively located in the three clearance spaces. The width of the I-shaped support slide rods 404 is equal to or slightly greater than the thickness of the partition 61. When the five guide blocks 103 are connected end to end, the three I-shaped support slide rods 404 are respectively located directly below the three partitions 61. The support rod 403 and the I-shaped support slide rod 405 are located on both sides of the multiple extrusion plates 104. The support rod 403 and the I-shaped support slide rod 405 support the two extrusion plates 104 on both sides respectively.

[0037] When the width of the extrusion space needs to be increased, the telescopic component 406 retracts. The telescopic component 406 drives the I-shaped support slide rod 405 to move within the guide groove 402 and away from the multiple extrusion plates 104, thereby providing space for the movement of the multiple extrusion plates 104. The multiple extrusion plates 104 move, and the extrusion plates 104 drive the I-shaped support slide rod 405 and the three I-shaped support slide rods 404 to move within the guide groove 402, thereby enabling the I-shaped support slide rod 405 and the three I-shaped support slide rods 404 to adapt to the movement of the multiple extrusion plates 104.

[0038] Multiple extrusion plates 104 extruded electrode group edge plates and electrode groups (such as Figure 8 As shown), three I-shaped support slide rods 404 are connected end to end, and the three I-shaped support slide rods 404 are located at the end of the guide groove 402 away from the telescopic member 406. The telescopic member 406 extends and drives the I-shaped support slide rod 405 to move. The I-shaped support slide rod 405 contacts the adjacent I-shaped support slide rod 404. At this time, the I-shaped support slide rod 405, the three I-shaped support slide rods 404 and the support rod 403 limit the distance between the multiple extrusion plates 104, thereby preventing the multiple extrusion plates 104 from being deformed by the rebound force of the pole group edge plate and the pole group.

[0039] The battery casing 6 is placed upside down on top of the three I-shaped support slide bars 404. As the battery casing 6 moves downward, the telescopic component 407 retracts and moves synchronously with the battery casing 6 until the lower end of the sliding frame 401 contacts the top of the guide block 103. At this point, the battery casing 6 and the sliding frame 401 stop moving, and the telescopic component 107 extends. The telescopic component 107 drives the top material frame 106 to move upward. After the top of the top material frame 106 extends beyond the guide block 103, the top material frame 106 pushes the plug side plate and the electrode group upward until the plug side plate and the electrode group are completely pressed into the mounting groove 62. The battery casing 6 moves upward, and the battery casing 6 and the top material rack 106 move upward synchronously. At this time, the electrode group edge plate, the battery casing 6 and the electrode group move upward. Since the extrusion plate 104 cannot move upward, the extrusion plate 104 detaches from the battery casing 6. The electrode group naturally expands, extruding the electrode group edge plate into contact with the side wall of the mounting groove 62. Through the expansion force of the electrode group, the electrode group and the electrode group edge plate are fixed in the mounting groove 62. At this time, the top material rack 106 provides support for the electrode group edge plate, the battery casing 6 and the electrode group, making it easy to remove the battery casing 6 from the electrode group and the electrode group edge plate.

[0040] like Figure 1 , Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, in a preferred embodiment of the present invention, a concave straightening plate 501 is fixedly provided on the top of the support rod 403, and a movable straightening plate 502 is fixedly provided on the top of the I-shaped support slide rod 405.

[0041] In this embodiment of the invention, the internal width of the concave straightening plate 501 is the same as the width of the battery housing 6, and the internal length of the concave straightening plate 501 is less than the length of the battery housing 6. The battery housing 6 is placed upside down on the top of the I-shaped support slide bar 404, so that the battery housing 6 is located inside the concave straightening plate 501. When the moving I-shaped support slide bar 405 supports the extrusion plate 104, the I-shaped support slide bar 405 drives the movable straightening plate 502 to move. The movable straightening plate 502 pushes the battery housing 6 to straighten and clamp the battery housing 6, thereby playing a positioning role for the battery housing 6. After clamping the battery housing 6, the pressing accuracy of the electrode group and electrode group edge plate is avoided due to vibration and other reasons.

[0042] like Figure 1 , Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, in a preferred embodiment of the present invention, a rear alignment plate 503 is fixed on the rear inner wall of the sliding frame 401, and a front alignment plate 504 is fixed on the front inner wall of the sliding frame 401. The distance between the rear alignment plate 503 and the front alignment plate 504 is equal to the length of the long side of the mounting groove 62.

[0043] In this embodiment of the invention, when the pole group and the pole group edge plate are placed into the extrusion space, the sliding frame 401 moves downward. The sliding frame 401 drives the rear alignment plate 503 and the front alignment plate 504 to be located at the lower part of the extrusion plate 104. At this time, when the pole group and the pole group edge plate are placed into the extrusion space, the rear alignment plate 503 and the front alignment plate 504 play a positioning role for the front and rear positions of the pole group and the pole group edge plate, thereby improving the placement accuracy of the pole group and the pole group edge plate.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
