[0002] With the rapid development of the lithium battery industry, the market demand for lithium battery capacity and performance is increasing. The capacity of lithium battery factories is rapidly increasing, while the production cycle is shortening. When batteries undergo negative pressure formation, the accuracy of the alignment between the negative pressure nozzle and the battery needs to be more precisely guaranteed. Usually, the accuracy of the relative position between the battery and the negative pressure nozzle is achieved through the pin hole positioning structure in the battery carrier and storage space. However, in actual production, there are machining accuracy errors in the processed parts, which can lead to a lack of guarantee for the vacuum degree on the negative pressure nozzle.

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0025] refer to Figures 1 to 4 , Figure 1 A perspective view of a battery pressing module 1 provided in an embodiment of the present invention is shown; Figure 2 This diagram shows a partial structural schematic of a battery pressing module 1 provided in an embodiment of the present invention; Figure 3 This diagram shows a schematic diagram of the liquid injection unit 30 of a battery pressing module 1 provided in an embodiment of the present invention; Figure 4 The diagram shows a bottom view of a battery pressing module 1 provided in an embodiment of the present invention.

[0026] like Figures 1 to 4 As shown, the technical solution provided in this application is a battery pressing module 1, characterized in that it includes:

[0027] Material carrier 2, along the first direction ( Figure 1 Extending in the middle X direction, it is used to place multiple batteries 9, the multiple batteries 9 along the second direction (shown in the X direction). Figure 1 (As shown in the Y direction) Interval settings.

[0028] The first pressing assembly 3, located on one side of the material carrier assembly along the first direction, includes multiple liquid injection units 30. Each of the multiple liquid injection units 30 corresponds to one of the multiple batteries 9 along the first direction, and each battery 9 has an injection hole 90 on the side facing the liquid injection unit 30. Each liquid injection unit 30 includes a negative pressure suction nozzle 31 and a bending plate 4. The negative pressure suction nozzle 31 extends along the first direction, passes through the bending plate 4, and corresponds to the injection hole 90. Along the second direction, the bending plate 4 is sized to fit the battery 9.

[0029] The second pressing component 8 is located on the other side of the material loading component along the first direction, and includes a pushing device for pushing the battery 9 along the first direction to the negative pressure suction nozzle 31 and the liquid injection hole 90 for insertion, and the bending plate 4 is inserted into and limited by the battery 9.

[0030] This application provides a battery pressing module 1, which, by setting a bending retaining plate 4, first performs secondary positioning of the battery 9 before the negative pressure suction nozzle 31 is positioned to engage with the battery 9, thus avoiding the failure of the negative pressure of the battery 9 due to misalignment of the negative pressure suction nozzle 31. The bending retaining plate 4 is adapted to the size of the battery 9 along the second direction, i.e., the width direction of the battery 9, so that the first positioning plate 41 and the second positioning plate 42 can abut and limit the battery 9 against both sides. In addition, the bending retaining plate 4 is independently installed on the negative pressure suction nozzle 31, which facilitates quick disassembly and replacement. For different models of batteries 9, quick-change parts can be used to avoid the inefficiency of manual screw installation and removal.

[0031] In some embodiments, reference Figures 1 to 4The bending plate 4 includes a connecting plate 40, a first positioning plate 41, and a second positioning plate 42. The connecting plate 40 extends along a second direction and has a first through hole 43 corresponding to the negative pressure suction nozzle 31. The first positioning plate 41 and the second positioning plate 42 are located on the side of the connecting end facing the material loading assembly 2 along the first direction, and are respectively located at both ends of the connecting plate 40 along the second direction, for abutting and limiting the battery 9 on both sides along the second direction through the first positioning plate 41 and the second positioning plate 42. The first positioning plate 41 and the second positioning plate 42 have corresponding positioning grooves 44 on their opposing sides along the second direction.

[0032] For example, the first positioning plate 41 and the second positioning plate 42 are respectively disposed at both ends of the connecting plate 40, forming a U-shaped structure with an opening facing the battery 9, and are positioned by the first positioning plate 41 and the second positioning plate 42 abutting against both sides of the battery 9 along the second direction.

[0033] In some embodiments, reference Figures 1 to 4 The injection unit 30 also includes an auxiliary clamping plate 5, which includes a limiting plate 50, a first clamping plate 51, and a second clamping plate 52. The limiting plate 50 is located on the side of the connecting plate 40 facing the injection hole 90 along the first direction, and has a second through hole 53 corresponding to the first through hole 43. The first clamping plate 51 is located on the side of the first positioning plate 41 facing the second positioning plate 42 along the second direction, and has a positioning protrusion 54 corresponding to the positioning groove 44. The second clamping plate 52 is located on the side of the second positioning plate 42 facing the first positioning plate 83 along the second direction, and has a positioning protrusion 54 corresponding to the positioning groove 44. The two ends of the limiting plate 50 along the two directions are respectively connected to the first clamping plate 51 and the second clamping plate 52.

[0034] For example, the auxiliary clamping plate 5 can further reduce the distance between the first positioning plate 41 and the second positioning plate 42, thereby adapting a smaller battery 9 through the first clamping plate 51 and the second clamping plate 52. The second through hole 53 on the limiting plate 50 corresponds to the first through hole 43 on the connecting plate 40, ensuring the precise alignment of the negative pressure suction nozzle 31. The positioning protrusions 54 on the first clamping plate 51 and the second clamping plate 52 correspond to the positioning grooves 44, further improving the positioning accuracy of the battery 9.

[0035] In some embodiments, reference Figures 1 to 4 Along the third direction ( Figure 1 (As shown in the Z direction), the height of the first clamping plate 51 is greater than the height of the first positioning plate 41, and the height of the second clamping plate 52 is greater than the height of the second positioning plate 42. Limiting protrusions 55 are provided at both ends of the first clamping plate 51 facing the first positioning plate 41 along the third direction, and at both ends of the second clamping plate 52 facing the second positioning plate 42 along the third direction, extending along the first direction for engaging and fixing with the first positioning plate 41 and the second positioning plate 42.

[0036] For example, the height of the first card plate 51 and the second card plate 52 is greater than the height of the corresponding positioning plate 83, forming a stepped structure. The limiting protrusion 55 extends along the first direction and is engaged and fixed with the positioning plate 83 to increase the stability of the connection between the auxiliary card plate 5 and the bent card plate 4.

[0037] In some embodiments, reference Figures 1 to 4 The first positioning plate 41 and the second positioning plate 42 are both inclined towards the end of the battery 9 along the first direction and closer to the negative pressure suction nozzle 31. The first clamping plate 51 and the second clamping plate 52 are both inclined towards the end of the battery 9 along the first direction and closer to the negative pressure suction nozzle 31. The bending clamping plate 4 and the auxiliary clamping plate 5 are both made of polyoxymethylene (POM).

[0038] For example, the positioning plate 83 and the clamping plate, which are inclined inward, can form a "trumpet-shaped" guide structure that can tolerate greater initial positional deviations. When the battery 9 is inserted, even if the battery 9 is not perfectly positioned initially, the inclined surface can guide the battery 9 to automatically adjust to the correct position. The polyoxymethylene (POM) material has excellent electrical insulation, solvent resistance, and processability, while not causing stress scratches or dents to the aluminum casing surface of the battery 9, thus reducing defects in the appearance of the battery 9.

[0039] In some embodiments, reference Figures 1 to 4 The battery pressing module 1 also includes a base plate 7, and a first pressing assembly 3, a material loading assembly 2, and a second pressing assembly 8 are spaced apart on the top of the base plate 7 along a first direction. The first pressing assembly 3 also includes a first frame 71, a fixing plate 72, and a leakage guide 73. The first frame 71 is located on the side of the negative pressure suction nozzle 31 away from the liquid injection hole 90 along the first direction. The first frame 71 extends along a third direction and its bottom passes through the base plate 7. The fixing plate 72 is fixedly connected to the base plate 7 and the first frame 71 respectively. One end of the leakage guide 73 along the first direction is connected to the first frame 71, and a leakage collection box 74 is provided on its top. The leakage collection box 74 extends along a second direction and is correspondingly located below the negative pressure suction nozzle.

[0040] For example, one end of the leakage guide 73 along the first direction is connected to the first frame 71, and a leakage collection box 74 is provided on the top. The leakage collection box 74 extends along the second direction and is correspondingly located below the negative pressure suction nozzle, which can effectively collect the leaked electrolyte and prevent contamination.

[0041] In some embodiments, reference Figures 1 to 4The second pressing assembly 8 also includes a second frame 80, a first telescopic cylinder 81, and a second telescopic cylinder 82. The second frame 80 extends along a third direction and its bottom is inserted through the base plate 7. The first telescopic cylinder 81 is located above the material loading assembly 2 and its two ends along the first direction are respectively connected to the top of the first frame 71 and the top of the second frame 80. The second telescopic cylinder 82 is located at the bottom of the base plate 7 and its two ends along the first direction are respectively connected to the bottom of the first frame 71 and the bottom of the second frame 80. The base plate 7 has a guide hole 70 corresponding to the second frame 80. The guide hole 70 extends along the first direction and is used to drive the second frame 80 to move relative to the first frame 71 along the guide hole 70 via the first telescopic cylinder 81 and the second telescopic cylinder 82.

[0042] For example, the coordinated action of the upper first telescopic cylinder 81 and the lower second telescopic cylinder 82 forms a dual-pivot drive mode, reducing the swaying of the second frame 80 during movement and improving positioning accuracy. The base plate 7 is provided with guide holes 70 extending along a first direction, through which the second frame 80 moves, allowing for a wider range of stroke adjustment. The design of the guide holes 70 allows the range of motion of the second frame 80 to be changed by adjusting the cylinder stroke without replacing the hardware.

[0043] In some embodiments, reference Figures 1 to 4 The material loading assembly 2 includes a material loading basket 20 and a material loading plate 23. The material loading plate 23 extends along a second direction and is located on top of the base plate 7. The material loading basket 20 is located on top of the material loading plate 23 with its opening facing upwards. The material loading basket 20 has a first working area 21 and a second working area 22 at its two ends along a first direction, respectively. The first working area 21 is corresponding to the liquid injection unit 30, and the second working area 22 is corresponding to the material pushing device. The material loading plate 23 has a first stop 24 and a second stop 25 at its two ends along the first direction, respectively, for abutting and limiting the material loading basket 20 at its two ends along the first direction.

[0044] For example, the material plate ensures the precise positioning of the material basket 20 on the material plate 23 by the first stop 24 and the second stop 25 at both ends along the first direction, reducing positional deviation. The design of the material basket 20 and the material plate 23 can be adjusted according to the size and shape of the battery 9. By replacing the material basket 20 with a different size or adjusting the position of the stop, it can quickly adapt to different models of batteries 9 and facilitate disassembly and cleaning operations.

[0045] In some embodiments, reference Figures 1 to 4The feeding device includes a pusher block 60, a first connecting rod 61, a mounting plate 62, and a second connecting rod 63. The pusher block 60 extends along a second direction and is located between the first telescopic cylinder 81 and the second stop portion 25, and on the side of the second frame 80 facing the second working area 22 along a first direction. The first connecting rod 61 extends along the first direction, with both ends connected to the pusher block 60 and the second frame 80, respectively. The mounting plate 62 is located on the side of the second frame 80 away from the second stop portion 25 along the first direction. The second connecting rod 63 extends along the first direction, with both ends connected to the mounting plate 62 and the second stop portion 25, respectively.

[0046] For example, the design of the first connecting rod 61 and the second connecting rod 63 forms a stable frame structure, and the pusher block 60 is connected to the second frame 80 through the first connecting rod 61, ensuring rigidity and stability during the pushing process, effectively reducing shaking during the pushing process, and ensuring the stability of the pushing process. In addition, the design of the pusher block 60 and the connecting rod can be adjusted according to the size and shape of the battery 9. By replacing the pusher block 60 with a different size or adjusting the length of the connecting rod, it can be quickly adapted to different models of batteries 9.

[0047] In some embodiments, reference Figures 1 to 4 The second pressing assembly 8 also includes a positioning plate 83, a slide rod 84, and multiple sliders 85. The positioning plate 83 extends along a second direction and is located at the bottom of the base plate 7, correspondingly positioned below the negative pressure suction nozzle 31. The slide rod 84 extends along a first direction and is respectively located on both sides of the second telescopic cylinder 82 along a third direction, with its two ends along the first direction connected to the positioning plate 83 and the bottom of the second frame 80, respectively. The base plate 7 has slide rails 75 corresponding to the slide rod 84, and multiple sliders 85 are spaced apart at the bottom of the material carrier plate 23 and are slidably connected to the slide rod 84.

[0048] For example, the positioning plate 83 and the slide bar 84 cooperate to form a stable guide structure. Multiple sliders 85 are spaced apart at the bottom of the material carrier plate 23 and are slidably connected to the slide bar 84. The combination of the positioning plate 83, the slide bar 84 and the sliders 85 forms a stable guide system, which plays an auxiliary guiding role, so that the material carrier plate 23 and the material basket 20 are moved as a whole and pushed by the pushing device.

[0049] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
