Description

Technical Field

[0001] This invention designs equipment related to the manufacturing of new energy battery modules, specifically involving a device for unpacking and stacking battery cell packaging. Background Technology

[0002] Battery cells are a crucial component of modern electronic products, widely used in devices such as mobile phones, tablets, and laptops. Before use, battery cells need to be packaged to protect them from damage during transportation and storage. Foam is a common packaging material for battery cells, offering advantages such as lightness, flexibility, and good shock resistance. It effectively absorbs external impacts and vibrations, protecting the battery cells from collisions and abrasion.

[0003] However, during battery manufacturing, the foam needs to be removed to allow for the insertion of other components such as the positive and negative terminals of the battery cell. Currently, the destacking and stacking of foam is typically done manually. While this traditional method meets production needs, it also has some shortcomings.

[0004] First, it requires significant human resources. A single foam stack may require multiple workers operating simultaneously, consuming substantial manpower and increasing production costs. Furthermore, the long operation cycle and slow manual depalletizing and stacking speed make it difficult to meet the demands of high-volume production lines. This can lead to production line stagnation or slowdowns, impacting the efficiency of the entire production process. Second, manual operation introduces safety concerns. Because foam is lightweight and fragile, operators must handle it with care; otherwise, it may break, shift, or result in waste due to mishandling. Fatigue and repetitive labor can also reduce operator focus and patience, further increasing safety risks. Summary of the Invention

[0005] Based on the above description, the present invention provides a device for unpacking and stacking battery cell packaging to solve the aforementioned technical problems in the prior art.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

The two gripping components on opposite sides cooperate to clamp the battery cell packaging.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0035] like Figures 1 to 7 As shown, this application provides a device for unpacking and stacking battery cell packages, which includes a truss 10, a lateral movement mechanism 20, a mounting frame 30, and a gripping mechanism 40.

[0036] The truss 10 is arranged laterally. In actual use, the two ends of the truss 10 are generally set on the side frame 11 with a certain height, so that the side frame 11 and the truss 10 form a gantry structure.

[0037] The mounting bracket 30 is movably mounted on the truss 10. The lateral movement mechanism 20 is used to drive the mounting bracket 30 to move laterally along the truss 10. The lateral movement mechanism 20 is generally a lateral telescopic cylinder or a lead screw motor.

[0038] In the embodiments of this application, the mounting frame 30 includes a mounting plate 31 and a support plate 32. The mounting plate 31 is vertically arranged and slidably mounted on one side of the truss 10. The support plate 30 is laterally connected to the lower end of the mounting plate 31. Side plates 33 are connected to both sides of the mounting plate 31 and the support plate 32 to enhance the connection stability between the mounting plate 31 and the support plate 32.

[0039] In this application, the gripping mechanism 40 includes a first cylinder 41, a fixing frame 42, and a plurality of gripping components 43.

[0040] The first cylinder 41 is vertically mounted on the support plate 32, and the cylinder axis of the first cylinder 41 passes downward through the support plate 32 and is connected to the fixed frame 42.

[0041] To ensure the lifting stability of the fixed frame 42, the gripping mechanism 40 also includes two balancing components 44. The balancing components 44 include a balancing frame 441 and a second cylinder 442. The second cylinder 442 is vertically arranged on one side of the first cylinder 41. The cylinder axis of the second cylinder 442 passes downward through the support plate 32 and is connected to the mounting frame 42. The balancing frame 441 includes two connecting rods 4411 and a balance rod 4412. The two connecting rods 4411 are vertically arranged through the support plate 32 and connected to the fixed frame 42. The balance rod 4412 is connected to the upper end of the two connecting rods 4411. This helps to maintain the balance and stability of the gripping mechanism and allows for more accurate control of the lifting height and position of the fixed frame 42 during operation.

[0042] In the embodiments of this application, the fixing frame 42 includes a reinforcing plate 421 and a suspension rectangular frame 422. The suspension rectangular frame 422 is a rectangular frame structure formed by four suspension rods 4221. The reinforcing plate 421 is connected to the middle of the suspension rectangular frame 422. The cylinder shaft of the first cylinder 41, the connecting rod 4411, and the cylinder shaft of the second cylinder 442 are all connected to the reinforcing plate 421.

[0043] The reinforcing plate 421 can improve the load-bearing capacity and durability of the fixed frame 42, making the gripping mechanism 40 more stable during operation. The suspended rectangular frame 422 can maintain the shape and structure of the fixed frame 42 and prevent it from deforming or twisting, thereby helping to improve its service life and reliability. The four suspension rods 4221 can balance and distribute the weight and pressure of the fixed frame 42, providing balanced support force, making the entire gripping mechanism 40 more stable and smooth during lifting.

[0044] In a preferred embodiment of this application, the suspension rod 4221 is a tubular rod structure with a regular hexagonal cross-section. This structure provides good load-bearing capacity and stability. Each side of the suspension rod 4221 has several through holes along its length, which can reduce the weight of the suspension rod 4221, thereby reducing the weight of the entire gripping mechanism 40. A right-angled triangular connector 4222 is provided between two adjacent suspension rods 4221 to balance and distribute the force and pressure between the suspension rods 4221, avoiding excessive deformation or damage. Each right-angled side of the connector 4222... The mechanism unfolds to both sides to form three connecting surfaces, which are respectively connected to the three sides of the suspension rod 4221 by fastening bolts 4223. This enhances the tightness and reliability of the connection between the suspension rod 4221 and the connecting piece 4222, making the operation of the entire gripping mechanism more stable and safe. In addition, the through hole design on the suspension rod 4221 allows for flexible selection of the installation position of the connecting piece 4222. The size of the suspension rectangular frame 422 can be adjusted according to different gripping item sizes, thereby improving the applicability and flexibility of the gripping mechanism 40 and achieving more precise and efficient gripping operations.

[0045] There are four gripping components 43, which are distributed at the lower end of the mounting bracket 42 according to the four vertices of the rectangle.

[0046] Distributing the gripping components 43 at the four vertices of the mounting frame 42 increases the stability of the entire mechanism, ensuring that the center of gravity is evenly distributed on the four points when gripping the battery cell package. Since the gripping components 43 are fixed at the four corners of the bottom of the mounting frame 42, the gripping position and force can be controlled and adjusted more accurately, thereby improving the gripping accuracy and success rate. This arrangement can make the most of the space in the working area and complete the gripping task without occupying too much space.

[0047] Packaging components used for battery cell packaging generally include foam and a stacking base plate. The gripping assembly 43 includes a fixed plate 431, movable grippers 432, and a drive unit 433. The fixed plate 431 is connected to the mounting frame 42. The movable grippers 432 are movably mounted on the lower end of the fixed plate 431. Each movable gripper 432 has a first gripping part and a second gripping part spaced apart from top to bottom. The opposite first gripping part is used to grip the foam component, and the opposite second gripping part is used to grip the pad. The drive unit 433 is used to drive the movable grippers 432 to move, so that the two opposite movable grippers 432 move closer or further apart.

[0048] The organic combination of the fixed plate 431, the movable gripper 432, and the drive component 433 gives the gripping assembly 43 advantages such as high precision, high adaptability, high stability, and high efficiency. It can meet different gripping needs and has good practicality. Using different gripping parts can better adapt to the material characteristics and strength differences of foam parts and pads, thereby improving the success rate and reliability of gripping. However, the material of the pad is usually harder than that of the foam parts. If the gripper of the foam parts is used to grip the pad, it may not be able to clamp it firmly.

[0049] Specifically, a slide rail 4311 is provided at the lower end of the fixed plate 431. The movable gripper 432 includes a slider 4321, a side plate 4322, and a base plate 4323. The slider 4321 is slidably connected to the slide rail 4311. The side plate 4322 and the base plate 4323 form an L-shape. The upper end of the side plate 4322 is connected to the slider 4321. The driving component 433 is a telescopic cylinder, which is set on one side of the fixed plate 431 and is used to drive the slider 4321 to move along the slide rail. The slide rail design can improve the movement accuracy of the movable gripper 432, thereby realizing precise control of the gripping position and force, and also increasing the stability and balance of the entire device.

[0050] The first gripping part includes a first fixed seat a1, a first clamping block a2 and an elastic rod a3. The second gripping part includes a second fixed seat b1 and a pad b2. The first fixed seat a1 and the second fixed seat b1 are spaced apart from top to bottom on the side plate 4322. The first clamping block a2 is connected to the first fixed seat a1 through the elastic rod a3. The pad b2 is disposed on the surface of the second fixed seat b1.

[0051] The elastic rod a3 connects the first fixed seat a1 and the first clamping block a2. When gripping foam parts, the pressure of the first clamping block a2 can be adaptively adjusted according to the characteristics and shape of the items, so that the clamping force is more appropriate and will not damage the items. The design of the pad b2 can ensure that the clamping force is uniform and will not be deformed or damaged.

[0052] In a preferred embodiment of this application, the gripping component 43 further includes a pressing component 434, which includes a pressing rod 4341, a pressing block 4342, and a spring 4343. The pressing rod 4341 is vertically inserted through the fixing plate 431, the pressing block 4342 is disposed at the lower end of the pressing rod 4341, and the spring 4343 is disposed between the fixing plate 431 and the pressing block 4342.

[0053] 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, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
