[0002] The battery module is composed of many battery cells combined together, plus a protective circuit and a protective shell. The production process from a simple battery cell to a battery pack is quite complicated, which includes a gluing station for applying glue to the surface of the battery cell. The gluing of the battery cell surface before assembly not only serves the purpose of mutual connection and fixation, but also may serve the purpose of insulation and heat dissipation. Although the existing gluing mechanism can apply glue to the battery cell, in order to improve the bonding effect of the battery cell during the gluing process, the glue is usually applied evenly, and the glue needs to be applied by moving the glue spray gun. During this process, the glue spray gun will slide back and forth on the outer surface of the battery cell, which is easy to cause damage to the battery cell. Utility Model Content

[0026] The utility model is further described below in conjunction with the accompanying drawings.

[0027] like Figures 1 to 3 The utility model provides an embodiment: a battery cell gluing mechanism, comprising a conveyor belt 1 for conveying battery cells 100, a gluing assembly 2 is arranged at the rear of the conveyor belt 1, and the battery cells 100 can be glued by the gluing assembly 2. The gluing assembly 2 comprises a base 21 fixed at the rear of the conveyor belt 1, a fixed frame 25 driven by a moving assembly is arranged on the base 21, and a gluing spray gun 27 can be easily moved by the moving assembly; the bottom of the fixed frame 25 is connected to a fixed plate 26 via a spring 211, the upper end of the spring 211 is fixed to the fixed frame 25, and the lower end is fixed to the fixed plate 26. A gluing spray gun 27 is fixed to the bottom of the fixed plate 26. The spring 211 can play a buffering role when the gluing spray gun 27 slides back and forth on the outer surface of the battery cell 100, thereby reducing damage to the battery cell.

[0028] In an embodiment of the utility model, the number of the springs 211 can be two, and the springs 211 are embedded with a guide rod 210; the lower end of the guide rod 210 is fixed to the top of the fixing plate 26, and the upper end penetrates the fixing frame 25. The fixing frame 25 is provided with a through hole for the guide rod 210 to move, so that when the spring 210 is squeezed, the guide rod 210 can move up and down in the through hole.

[0029] In one embodiment of the utility model, the mobile assembly includes an X-axis linear module 22 fixed on a base 21, a Y-axis linear module 23 is fixed on a slide of the X-axis linear module 22, a Z-axis linear module 24 is fixed on a slide of the Y-axis linear module 23, and a glue spray gun 27 can be driven to move left and right through the X-axis linear module 22, the glue spray gun 27 can be driven to move forward and backward through the Y-axis linear module 23, and the glue spray gun 27 can be driven to move up and down through the Z-axis linear module 24, which is convenient for subsequent glue coating. A fixed frame 25 is fixed on the slide of the Z-axis linear module 24.

[0030] like Figure 3In one embodiment of the utility model, a U-shaped block 28 is fixed to the bottom of the fixing plate 26, and a glue spray gun 27 is fixed to the U-shaped block 28 via bolts 29, and the glue spray gun 27 can be easily disassembled and replaced by the bolts 29. The fixing plate 26 and the U-shaped block 28 are both provided with through holes for the glue spray gun 27 to pass through, and the glue spray gun 27 is passed through the through holes, and then the glue spray gun 27 is pressed against by two bolts 29, so that the glue spray gun 27 is fixed.

[0031] like Figure 4 In one embodiment of the utility model, a plurality of groups of limiting components are arranged on the conveyor belt 1, and the battery cell 100 can be limited by the limiting components, so that the gluing position can be accurate when the glue spray gun 27 glues the battery cell 100; the limiting components include four limiting blocks 3 fixed on the conveyor belt 1, and when the battery cell 100 is placed on the limiting blocks 3, the four limiting blocks 3 are located at the four corners of the battery cell 100, so that the battery cell 100 can be better limited; the top of the limiting block 3 has a placement groove 31 for placing the battery cell 100.

[0032] The limiting block 3 has a first inclined surface 32 above the placement groove 31. When the battery cell 100 is placed in the placement groove 31, the first inclined surface 32 can play a guiding role, making it easier for the battery cell 100 to slide into the placement groove 31.

[0033] In one embodiment of the utility model, battery cells 100 are placed on each set of limiting components. When the conveyor belt 1 drives the battery cells 100 to move to the glue coating component 2, the conveyor belt 1 pauses, and the glue coating spray gun 27 is driven by the Z-axis linear module 24 to move downward to the battery cells 100 for gluing. After the gluing is completed, the conveyor belt 1 starts and pauses when the next battery cell 100 moves to the glue coating component 2, and so on.

[0034] Alternatively, a battery cell 100 is placed every two sets of limit assemblies. When the conveyor belt 1 drives the battery cell 100 to move to the glue coating assembly 2, the Z-axis linear module 24 drives the glue coating spray gun 27 to move downward, so that when the battery cell 100 moves below the glue coating spray gun 27, the glue coating spray gun 27 can just touch the battery cell 100, and the conveyor belt 1 does not stop, but continues to drive the battery cell 100 to move. At the same time, the X-axis linear module 22 drives the glue coating spray gun 27 to move, so that the battery cell 100 is coated with glue during the movement; after the gluing is completed, the Z-axis linear module 24 drives the glue coating spray gun 27 to move upward, and the X-axis linear module 22 drives the glue coating spray gun 27 to return, and continues to coat the next battery cell 100 with glue.

[0035] In order to improve the accuracy, a through-beam sensor can be set on the conveyor belt 1. When the through-beam sensor senses the battery cell 100, the Z-axis linear module 24 drives the glue spray gun 27 to move downward, so that when the battery cell 100 moves below the glue spray gun 27, the glue spray gun 27 can just touch the battery cell 100.

[0036] In an embodiment of the present invention, the bottom of the placement groove 31 is made of rubber material, so as to buffer the battery cell 100 and avoid damage to the battery cell 100.

[0037] like Figure 5 In one embodiment of the utility model, a storage component 4 for storing the battery cell 100 is arranged on the left side of the glue coating component 2; the storage component 4 includes a placement table 41, and a plurality of positioning components are arranged on the placement table 41 for positioning the battery cell 100. The positioning component includes three positioning blocks 42 fixed on the placement table 41, and the top of the positioning block 42 has a storage groove 43 for storing the battery cell 100. When the battery cell 100 is placed on the positioning block 42, two of the positioning blocks 42 are located at the two corners on the same side of the battery cell 100, and the other positioning block 42 is located in the middle of the other side of the battery cell 100, so that the battery cell 100 can be better positioned.

[0038] In one embodiment of the utility model, two positioning blocks 42 have a second inclined surface 44 above the storage slot 43 . When the battery cell 100 is placed in the storage slot 43 , the second inclined surface 44 can play a guiding role, making it easier for the battery cell 100 to slide into the storage slot 43 .

[0039] In an embodiment of the present invention, the bottom of the storage slot 43 is made of rubber material, so as to buffer the battery cell 100 and avoid damage to the battery cell 100 .

[0040] like Figure 6 In one embodiment of the utility model, the bottom of the placement table 41 is located below each group of positioning components and is fixed with a diffuse reflection sensor 6 through a mounting frame 5, which is used to sense whether the battery cell 100 is on the placement table 41, so as to facilitate the subsequent replenishment of the battery cell 100 on the placement table 41. The model of the diffuse reflection sensor 6 can be GTB6, but is not limited thereto. A channel 7 for the laser of the diffuse reflection sensor 6 to pass through is opened at the bottom of the placement table 41.

[0041] like Figure 1 In one embodiment of the utility model, a six-axis robot 8 for grabbing the battery cell 100 is arranged between the storage component 4 and the glue coating component 2. The six-axis robot 8 can grab the battery cell 100 from the storage component 4 to the limiting component, which is convenient for loading the battery cell 100.

[0042] The X-axis linear module, Y-axis linear module, Z-axis linear module, glue spray gun, diffuse reflection sensor, and six-axis robot in the utility model are all prior arts, which can be clearly understood by those skilled in the art and will not be described in detail here. The utility model protects the structural features of a battery cell glue coating mechanism.
