Description

Technical Field

[0001] This utility model relates to the field of lithium battery manufacturing, specifically to a core pack feeding device. Background Technology

[0002] In existing designs, the feeding device of the assembly machine addresses the issue of how to feed battery cells. For example, the applicant previously submitted a utility model patent application number CN202321424585.0 to the China National Intellectual Property Administration, entitled "A Feeding Device for an Assembly Machine." This patent solved the feeding problem but did not address how to inject electrolyte and vacuum the battery after assembly. The current practice is to assemble the battery into a semi-finished product, then soak it in an electrolyte container for a period of time before removing it and vacuuming it. This method requires a long waiting time, which is not conducive to rapid production. Therefore, the applicant has improved the existing feeding device so that it can complete the injection of electrolyte and vacuuming during feeding. Utility Model Content

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0024] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] like Figures 1-4 As shown, a core package feeding device includes a fixed base 1, a slide rail 2, an upper clamping mechanism 3, a lower clamping mechanism 4, and a transverse movement mechanism 5. The slide rail 2 is installed in front of the fixed base 1 and is placed horizontally. The upper clamping mechanism 3 is slidably installed in front of the slide rail 2. The transverse movement mechanism 5 drives the upper clamping mechanism 3 to move horizontally left and right. The lower clamping mechanism 4 is located below the upper clamping mechanism 3. The upper clamping mechanism 3 is used to clamp the upper part of the product, and the lower clamping mechanism 4 is used to clamp the lower part of the product. The upper clamping mechanism 3 clamps the core package at the front end of the vibrator 9 to the lower clamping mechanism. The core package feeding device also includes at least one liquid injection module 6 and at least one vacuum module 7. The upper clamping mechanism 3 and the lower clamping mechanism 4 cooperate to allow the product to pass sequentially through the liquid injection module 6 and the vacuum module 7. An electrolyte injection module 6 is installed in front of the clamping mechanism 3. The electrolyte injection module 6 injects electrolyte into the core pack. The core pack with electrolyte injected enters the vacuum module 7. Specifically, the upper clamping mechanism 3, the lower clamping mechanism 4, and the transverse movement mechanism 5 cooperate to drive the product forward. When the upper clamping mechanism 3 clamps the product, the transverse movement mechanism 5 drives the upper clamping mechanism 3 to move forward one station. When the lower clamping mechanism 4 clamps the product, the upper clamping mechanism 3 releases the product. The transverse movement mechanism 5 drives the upper clamping mechanism 1 to move backward one station to prepare for sending the next product. In this way, the core pack can be moved forward station by station in a step-by-step manner. The core pack is a lithium-ion battery core pack. The transverse movement mechanism 5 is implemented by a swing arm and a cam mechanism. The cam mechanism drives the swing arm to swing, and the swing arm drives the upper slide plate 31 to move left and right along the slide rail.

[0027] like Figure 5-7As shown, the upper clamping mechanism 3 includes an upper slide plate 31, a lower cover plate 32, an upper clamping assembly, and an upper opening and closing drive assembly. The slide rail 2 is slidably connected to the upper slide plate 31. The lower cover plate 32 is installed below the upper slide plate 31. Multiple sets of upper clamping assemblies are installed in front of the upper slide plate 31. The upper clamping assembly includes a first clamp 34 and a second clamp 35. The first clamp 34 and the second clamp 35 are respectively provided with clamping grooves for clamping products. The upper opening and closing drive assembly drives the first clamp 34 and the second clamp 35 to open and close. The upper opening and closing drive assembly includes a first rack 36, a second rack 37, a first gear 38, an upper push block 39, an upper guide rod 310, an upper guide sleeve 311, an upper connecting plate 312, and a power element. The first rack 36 and the second rack 37 are slidably mounted between the upper slide plate 31 and the lower cover plate 32. The first rack 36 and the second rack 37 respectively mesh with the first gear 38, that is, when the first rack 36 moves, it also drives the second rack 37 to move through the first gear 38. A first chuck 34 is installed in front of the first rack 38, and the first rack 36 extends from the rear of the upper slide block. A second chuck 35 is installed in front of the second rack 37. The upper push block 39 is located behind the first rack 36, and the upper guide rod 310 is connected to the rear of the upper push block 39. The upper guide rod 310 is fitted inside the upper guide sleeve 311. The upper guide sleeve 311 is installed in the fixed seat 1. The upper guide rod 310 is connected to the upper connecting plate 312 at its rear end. The power element can be a cylinder, oil cylinder, servo motor, or cam mechanism to drive the upper connecting plate 312 to move forward. The upper connecting plate 312 drives the upper guide rod 310 to move forward. The upper guide rod 310 drives the upper push block 39 to move forward. The upper push block 39 moves forward and pushes against the first rack 36 to move forward. Since the first rack 36 and the second rack 37 respectively mesh with the first gear 38, the second rack 37 will retract, thereby opening the first chuck 34 and the second chuck 35. The first rack 37 is hooked by a screw at one end of the first return spring 313. The other end of the first return spring 313 hooks the lower cover plate 32. The first return spring 313 causes the first chuck 34 and the second chuck 35 to retract and close.

[0028] like Figure 8 and 9As shown, the lower clamping mechanism 4 includes a lower slide plate 41, an upper cover plate 42, a lower clamping assembly, and a lower opening and closing drive assembly. The upper cover plate 42 is installed above the lower slide plate 41. The lower clamping assembly includes a first clamping plate 43 and a second clamping plate 44. Multiple elastic clamping pins 45 are installed on the first clamping plate 43, and multiple movable clamps 46 are installed on the second clamping plate 44. The elastic clamping pins 45 and the movable clamps 46 are positioned correspondingly. The lower opening and closing drive assembly includes a third rack 47, a fourth rack 48, a second gear 49, a second return spring 410, and a power element. The third rack 47 and the fourth rack 48 are slidably installed between the lower slide plate 41 and the upper cover plate 42. 48 meshes with the second gear 49. The first clamping plate 43 is installed in front of the third rack 47, and the second clamping plate 44 is installed in front of the fourth rack 48. The tail of the first clamping plate 43 extends from the tail of the sliding seat 41. The power element drives the third rack 47 to move back and forth. The second return spring 410 is installed inside the sliding seat 41. The second return spring 410 pushes against the fourth rack 48. The power element can be a cylinder, a hydraulic cylinder, a servo motor, or a cam mechanism to drive the third rack 47 to move forward. Due to the action of the second gear 49, the fourth rack 48 moves backward, thereby opening the first clamping plate 43 and the second clamping plate 44. The closing principle is similar to that of the first chuck 34 and the second chuck 35 and will not be described in detail.

[0029] like Figure 1 As shown in Figures 2, 3, and 10, in this embodiment, there are two injection modules 6. Each injection module 6 includes an injection needle 61 and an injection needle mounting base 62. The injection needle 61 is mounted on the injection needle mounting base 62 and is located between the first clamp 34 and the second clamp 35. The injection needle mounting base 62 is mounted on the upper slide plate of the upper clamping mechanism. The injection needle 61 is connected to an injection pump 63 via a pipe. The injection pump 63 drives the electrolyte in the storage tank 64 to reach the injection needle 61. In addition, in this embodiment, there are two vacuum modules 7. Each vacuum module 7 includes a front vacuum plate 71 and a rear vacuum plate 72. A vacuum chamber 73 is formed between the front vacuum plate 71 and the rear vacuum plate 72. A sealing ring 74 is installed around the vacuum chamber 73. The vacuum chamber 71 is connected to a vacuum hole 75, which is connected to a vacuum pump via a pipe. The opening and closing drive assembly drives the front vacuum plate 71 and the rear vacuum plate 72 to open and close in the same way as the opening and closing of the first clamp 34 and the second clamp 35.

[0030] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be considered that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the protection scope of the present utility model.
