Description

Technical Field

[0001] This utility model relates to the field of battery cell production equipment technology, and more specifically, to a battery cell turnover box hoisting tool. Background Technology

[0002] Lithium-ion battery systems are mainly composed of individual cells connected in series and parallel. During the battery pack manufacturing process, the cells need to be manually transferred to the PACK section after the battery pack comes off the production line. The traditional method of manually transferring the cells is time-consuming, labor-intensive, and also poses safety hazards.

[0003] In the battery production process, lifting tools are also used to improve production efficiency. For example, Chinese patent document CN221140865U discloses a battery pack lifting device, which includes a box and a lifting frame set on the box. The box includes two side plates arranged opposite each other. A loading beam is provided on the outer side of the upper end of each side plate along the length direction. The lifting beam has a triangular groove with an open bottom along the length direction. The lifting frame includes two loading units. Each loading unit includes an L-shaped plate and a hook plate fixedly connected together. The L-shaped plate includes a short plate and a long plate arranged vertically. An electric push rod is provided on one of the long plates and fixedly connected to the other long plate. The hook plate is inserted into the triangular groove from bottom to top.

[0004] However, the L-shaped plate of the aforementioned hoisting device hooks onto the hoisting beam on the outside of the box body, and the L-shaped plate cooperates with the hoisting beam of the box body to hoist the box body. The L-shaped plate, i.e., the hoisting component and the hoisting beam, is not easy to position, and the hoisting component is difficult to hook accurately to the hoisting position of the hoisting beam, which affects the hoisting efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting tool for battery cell turnover boxes, which solves the problem that the lifting components of existing lifting devices are difficult to accurately position with the object to be lifted, thus affecting the lifting efficiency.

[0006] To achieve the above objectives, this utility model provides a battery cell turnover box lifting tool for lifting the turnover box from the inside, including a support frame; a first guide member is provided on each side of the support frame in a first direction, the first guide member being used to conform to the inner wall of the turnover box in the first direction; a second guide member is provided on each side of the support frame in a second direction, the second guide member being used to conform to the inner wall of the turnover box in the second direction; a lifting member is provided on each side of the support frame in the first direction for lifting the turnover box, the lifting member being connected to an adjustment device, the adjustment device adjusting the distance between the lifting member and the inner wall of the turnover box in the second direction to lift the lifting member and the turnover box.

[0007] Through the above technical solution, the first guide and the second guide are respectively used to conform to the inner walls of the turnover box in the first and second directions, so that the lifting component can be accurately positioned on the inner side of the turnover box. The position of the lifting component is adjusted by the adjustment device, thereby changing the distance between the lifting component and the inner wall of the turnover box in the second direction, and finally enabling the lifting component to be lifted onto the turnover box. The lifting component can be positioned, thus enabling precise positioning with the turnover box and improving lifting efficiency.

[0008] Furthermore, the support frame includes two sets of first support arms located on both sides of the support frame in a first direction, with each set of first support arms arranged along a second direction; the adjustment device is a linear spring located above the first support arm, one end of the lifting component is connected to the linear spring, and the other end extends through the first support arm into the turnover box.

[0009] The extension and retraction of the linear spring can drive the lifting component to move in the second direction, thereby adjusting the lifting component to the inner wall of the turnover box and improving the lifting accuracy of the lifting component.

[0010] Furthermore, the first support arm is provided with a sliding groove, the length direction of which is consistent with the second direction; the lifting component is disposed through the sliding groove.

[0011] The chute provides space for the movement of the lifting component, while also restricting its displacement in directions other than the second direction. This improves the stability of the lifting component's movement, prevents it from swaying in other directions, and enhances its positioning accuracy.

[0012] Furthermore, the first support arm is provided with a guide shaft, which is mounted on the first support arm via a support seat and is parallel to the length direction of the chute; one end of the lifting component is sleeved on the guide shaft, and the linear spring is coaxially arranged with the guide shaft.

[0013] The guide shaft and support base can precisely guide the movement direction of the lifting components, improving the accuracy of the lifting component's position adjustment. The linear spring is coaxially arranged with the guide shaft, simplifying the structural design; the extension and contraction direction of the linear spring is the axial direction of the guide shaft.

[0014] Furthermore, a stop plate is provided at the end of the guide shaft.

[0015] The stop plate is used to limit the compression space of the linear spring, so that the linear spring can extend and retract within the planned space, thereby ensuring the accuracy of the movement range of the lifting component and facilitating docking with the turnover box.

[0016] Furthermore, the lifting component is a hook structure, with the hook extending towards the inner wall of the turnover box, and the hook corresponding to the lifting hole of the turnover box.

[0017] The extension direction of the hook body of the hook structure facilitates the hoisting of the turnover box from the inside. The position of the hoisting hole corresponds to the hook body, so that the hook structure can be accurately positioned to the hoisting hole, making it convenient to lift the turnover box.

[0018] Furthermore, a protective pad is provided on the side of the hook structure facing the battery cell inside the turnover box. The protective pad is arranged along the length of the hook structure and extends to the hook body.

[0019] The protective pads are elastic and are generally made of polyurethane. The protective pads protect the battery cells and prevent the hook structure from directly contacting the battery cells and scratching them.

[0020] Furthermore, the first support arms on both sides are connected by the second support arm, the first guide is a guide plate and is disposed at both ends of the second support arm; the second guide is a guide post, and the guide post is connected to the second support arm through guide support.

[0021] The first guide component uses a guide plate, which increases its contact area with the inner wall of the turnover box, thus improving contact stability. The second guide component uses a guide post structure; the cylindrical surface of the guide post has a small contact area with the inner wall of the turnover box, reducing friction on the inner wall.

[0022] Furthermore, a pull rod is connected between the guide shafts on both sides of the first direction, and the two ends of the pull rod are connected to the guide shafts through connecting pieces.

[0023] Pulling the lever in the second direction moves the guide shaft within the support 7 and compresses the linear spring, causing the lifting component to move away from the lifting hole of the turnover box, thus detaching the entire lifting tool from the turnover box. Releasing the lever allows the lifting component to approach the turnover box and engage with the lifting hole, completing the lifting operation.

[0024] Furthermore, a lifting adapter plate is provided in the middle of the second support arm, and a lifting ring is installed on the top of the lifting adapter plate.

[0025] The use of a lifting adapter plate and lifting ring structure facilitates the lifting of turnover boxes by hoisting equipment and their transfer to other workstations on the production line, thereby improving production efficiency.

[0026] Compared with existing known technologies, the technical solution provided by this utility model has the following beneficial effects:

[0027] This utility model discloses a lifting tool for battery cell turnover boxes. A first guide and a second guide are respectively used to conform to the inner walls of the turnover box in a first direction and a second direction, allowing the lifting component to be accurately positioned inside the turnover box. The lifting component's position is adjusted via an adjustment device, changing the distance between the lifting component and the inner wall of the turnover box in the second direction, ultimately enabling the lifting component to be lifted onto the turnover box. The adjustable position of the lifting component allows for precise positioning with the turnover box, improving lifting efficiency.

[0033] The present invention will now be described in detail with reference to the accompanying drawings. The embodiments described herein are merely preferred embodiments of the present invention. Those skilled in the art can conceive of other ways to implement the present invention based on the preferred embodiments, and such other ways also fall within the scope of the present invention.

[0034] Example

[0035] Reference Figure 1This embodiment provides a lifting tool for battery cell turnover boxes, used to lift the turnover box from the inside. It includes a support frame 1; first guide members 10 are provided on both sides of the support frame 1 in a first direction, and the first guide members 10 are used to conform to the inner wall of the turnover box in the first direction; second guide members 11 are provided on both sides of the support frame 1 in a second direction, and the second guide members 11 are used to conform to the inner wall of the turnover box in the second direction; the first guide members 10 and the second guide members 11 are respectively used to conform to the inner walls of the turnover box in the first and second directions, so that the lifting member 8 can be accurately positioned to the inside of the turnover box. The support frame 1 has lifting members 8 on both sides of the first direction for lifting the turnover box. The lifting members 8 are connected to an adjusting device 15, which adjusts the distance between the lifting member 8 and the inner wall of the turnover box in the second direction to lift the turnover box. The lifting component 8 is adjusted in position by the adjusting device 15, which changes the distance between the lifting component 8 and the inner wall of the turnover box in the second direction, and finally enables the lifting component 8 to be lifted with the turnover box. The lifting component 8 can be adjusted in position, so as to accurately position it with the turnover box and improve the lifting efficiency.

[0036] Specifically, such as Figure 1 As shown, the support frame 1 includes two sets of first support arms 101 located on both sides of the support frame 1 in a first direction, i.e., the first support arms 101 are located on opposite sides of the support frame 1, and each set of first support arms 101 is arranged along a second direction. The adjusting device 15 is a linear spring located above the first support arms 101. One end of the lifting component 8 is connected to the linear spring, and the other end extends through the first support arm 101 into the turnover box. The extension and contraction of the linear spring can drive the lifting component 8 to move along the second direction, thereby allowing the lifting component 8 to be adjusted to the inner wall of the turnover box, improving the lifting accuracy of the lifting component 8. It should be noted that the first direction and the second direction are perpendicular to each other.

[0037] Furthermore, the first support arm 101 is provided with a groove 102, the length direction of which is consistent with the second direction; the lifting component 8 is disposed through the groove 102. The groove 102 provides space for the movement of the lifting component 8, while also restricting the displacement of the lifting component 8 outside the second direction, which can improve the movement stability of the lifting component 8, prevent the lifting component 8 from swinging in other directions, and improve the positioning accuracy of the lifting component 8.

[0038] In some embodiments, the first support arm 101 is provided with a guide shaft 5, which is mounted on the first support arm 101 via a support base 7 and is parallel to the groove length direction of the slide 102. One end of the lifting component 8 is sleeved on the guide shaft 5, and the linear spring is coaxially arranged with the guide shaft 5. Specifically, the lifting component 8 is fixed to the guide shaft 5 by a set screw 16, and the lifting component 8 can move together with the guide shaft 5. The guide shaft 5 and the support base 7 can accurately guide the movement direction of the lifting component 8, improving the accuracy of the position adjustment of the lifting component 8. The coaxial arrangement of the linear spring and the guide shaft 5 can simplify the structural design, and the extension and contraction direction of the linear spring is the axial direction of the guide shaft 5. Furthermore, a stop plate 6 is provided at the end of the guide shaft 5. The stop plate 6 is used to limit the compression space of the linear spring, so that the linear spring extends and contracts within the planned space, thereby ensuring the accuracy of the movement range of the lifting component 8 and facilitating docking with the turnover box.

[0039] In some embodiments, the lifting component 8 is a hook structure. The hook body of the hook structure extends towards the inner wall of the turnover box, facilitating the lifting of the turnover box from the inside. The hook body corresponds to the lifting hole of the turnover box, allowing the hook structure to be precisely positioned to the lifting hole for easy lifting of the turnover box. Furthermore, a protective pad 9 is provided on the side of the hook structure facing the battery cell inside the turnover box. The protective pad 9 is arranged along the length of the hook structure and extends to the hook body. The protective pad 9 is elastic and is generally made of polyurethane. The protective pad 9 protects the battery cell, preventing the hook structure from directly contacting the battery cell and scratching it.

[0040] In some embodiments, the two first support arms 101 are connected by the second support arm 103. The first guide member 10 is a guide plate and is disposed at both ends of the second support arm 103. The guide plate can increase its contact area with the inner wall of the turnover box, thereby improving contact stability. The second guide member 11 is a guide post, which is connected to the second support arm 103 through the guide support 13. The cylindrical surface of the guide post has a small contact area with the inner wall of the turnover box, reducing friction on the inner wall of the turnover box. It should be noted that a guide post pad 12 is connected between the guide post and the guide support 13. The guide post pad 12 sinks into the turnover box with the guide post. The cross-sectional area of ​​the guide post pad 12 is larger than that of the guide post. The guide post pad 12 can prevent the guide post from contacting the battery cell. The guide post pad 12 is also made of polyurethane material, which plays a protective role for the battery cell.

[0041] It is understandable that the extension and contraction of a linear spring requires the application of external force for control; in some embodiments, such as... Figure 1As shown, a pull rod 3 connects the guide shafts 5 on both sides in the first direction. The two ends of the pull rod 3 are connected to the guide shafts 5 via connecting pieces 4. Pulling the pull rod 3 in the second direction causes the guide shaft 5 to move within the support base 7 and compress the linear spring, causing the lifting component 8 to leave the lifting hole of the turnover box, thus detaching the entire lifting tool from the turnover box. Releasing the pull rod 3 allows the lifting component 8 to approach the turnover box and engage with the lifting hole, completing the lifting operation.

[0042] Furthermore, a lifting adapter plate 2 is provided in the middle of the second support arm 103, and a lifting ring 14 is installed on the top of the lifting adapter plate 2. The interior of the lifting adapter plate 2 is a hollow structure with both ends open, through which the tie rod 3 can pass, avoiding structural interference. The structure of the lifting adapter plate 2 and the lifting ring 14 facilitates the lifting of the turnover box by the lifting equipment and the transfer of the turnover box to other workstations on the production line, thereby improving production efficiency.
