[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A lithium-ion battery tab heat-sealing device includes a placement mechanism, a heat-sealing mechanism, and an unloading mechanism. The placement mechanism includes a tray, a limiting groove formed on the top of the tray, and a pad connected to the bottom of the inner cavity of the limiting groove. The heat-sealing mechanism includes a heat-sealing plate suspended on the top of the pad, a top cover sleeved on the top of the heat-sealing plate, and a hydraulic cylinder connected to the top of the top cover. The unloading mechanism includes multiple T-shaped columns sliding through the bottom of the tray, rollers movably embedded at the top of the T-shaped columns, a cylinder connected to the bottom of the tray, and a lifting plate connected to the movable end of the cylinder. The multiple T-shaped columns are all located on the top of the lifting plate.

[0007] By adopting the above technical solution, after the tabs are heat-sealed and during the unloading process, the moving end of the control cylinder contracts, and then the lifting plate rises. The lifting plate then pushes up the T-shaped columns and rollers. Since the lengths of the multiple T-shaped columns are different, the batteries lifted by the multiple rollers are placed at an angle. Then, under the action of weight, the batteries slide down and fall into the receiving box from the slope position, achieving the purpose of unified collection, eliminating manual unloading and improving the safety of unloading.

[0008] In a preferred embodiment, the present invention can be further configured as follows: multiple T-shaped columns are equally spaced and arranged in a matrix, the cylinder is located between the multiple T-shaped columns, and the length of the two T-shaped columns located on the front side of the cylinder is greater than the length of the two T-shaped columns located on the rear side of the cylinder.

[0009] In a preferred embodiment, the present invention can be further configured such that the top of the roller is flush with the bottom of the inner cavity of the limiting groove, and the roller is made of stainless steel.

[0010] In a preferred embodiment, the present invention can be further configured such that: two guide rods are installed at the bottom of the pallet, the two guide rods are located on both sides of the cylinder, and the guide rods are vertical and slide through the lifting plate.

[0011] In a preferred embodiment, the present invention can be further configured such that: a support frame is sleeved on the outer side of the pallet, and the hydraulic cylinder vertically penetrates the top of the support frame.

[0012] In a preferred embodiment, the present invention can be further configured such that: a plurality of support rods are installed at the bottom of the tray, and the bottom ends of the plurality of support rods are fixedly connected to the support frame.

[0013] In a preferred embodiment, the present invention can be further configured such that: the top of the pallet has a slope, the slope is located behind the limiting groove, and a receiving box is installed on the rear side of the pallet.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] 1. In this utility model, after the tabs are heat-sealed and during the unloading process, the movable end of the control cylinder retracts, and then the lifting plate rises. The lifting plate then pushes up the T-shaped columns and rollers. Since the lengths of the multiple T-shaped columns are not equal, the batteries lifted by the multiple rollers are placed at an angle. Then, under the action of weight, the batteries slide down and fall into the receiving box from the slope position, achieving the purpose of unified collection, eliminating manual unloading and improving the safety of unloading.

[0016] 2. In this utility model, the battery is placed inside the limiting groove, and then the tab part is attached to the top of the pad. Then the hydraulic cylinder is activated, and then the heat sealing plate cooperates with the pad to achieve heat sealing of the tab. The structure is simple and the heat sealing is convenient.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0031] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0032] The following describes, with reference to the accompanying drawings, some embodiments of a lithium-ion battery tab heat sealing device provided by this utility model.

[0033] Example 1:

[0034] Combination Figure 1-5 As shown, the present invention provides a lithium-ion battery tab heat sealing device, including a support mechanism 100, a heat sealing mechanism 200 and a unloading mechanism 300. The support mechanism 100 includes a support plate 110, a limiting groove 120 opened on the top of the support plate 110, and a pad 130 connected to the bottom of the inner cavity of the limiting groove 120.

[0035] The heat sealing mechanism 200 includes a heat sealing plate 210 suspended above the pad 130, a top cover 220 sleeved on the top of the heat sealing plate 210, and a hydraulic cylinder 230 connected to the top of the top cover 220.

[0036] The unloading mechanism 300 includes a plurality of T-shaped columns 310 that slide through the bottom of the pallet 110, rollers 320 that are movably embedded in the top of the T-shaped columns 310, a cylinder 330 connected to the bottom of the pallet 110, and a lifting plate 340 connected to the movable end of the cylinder 330. The plurality of T-shaped columns 310 are all located at the top of the lifting plate 340.

[0037] Furthermore, multiple T-shaped pillars 310 are equally spaced and arranged in a matrix. The cylinder 330 is located between the multiple T-shaped pillars 310. The length of the two T-shaped pillars 310 located in front of the cylinder 330 is greater than the length of the two T-shaped pillars 310 located behind the cylinder 330. This layout design ensures that the battery lifted by the multiple T-shaped pillars 310 can tilt, providing conditions for automatic unloading.

[0038] Furthermore, the top of the roller 320 is flush with the bottom of the inner cavity of the limiting groove 120. The roller 320 is made of stainless steel. This layout design allows the battery to be placed horizontally inside the limiting groove 120.

[0039] Furthermore, the top of the pallet 110 is provided with a slope, which is located behind the limiting groove 120. A receiving box 700 is installed on the rear side of the pallet 110. The slope can guide the batteries sliding down from the multiple rollers 320 so that the batteries can fall accurately into the receiving box 700.

[0040] Example 2:

[0041] Combination Figure 3-4 As shown, based on Embodiment 1, two guide rods 400 are installed at the bottom of the support plate 110. The two guide rods 400 are located on both sides of the cylinder 330. The guide rods 400 are vertical and slide through the lifting plate 340. The guide rods 400 can limit the lifting plate 340, making it move straight up and down, thus improving its stability during movement.

[0042] Example 3:

[0043] Combination Figure 1 As shown in the above embodiment, a support frame 500 is sleeved on the outer side of the pallet 110, and the hydraulic cylinder 230 penetrates vertically through the top of the support frame 500. The support frame 500 can lift the pallet 110 to accommodate the height of the staff and improve the comfort of use.

[0044] Furthermore, the bottom of the pallet 110 is equipped with multiple support rods 600, the bottom ends of which are fixedly connected to the support frame 500. The support rods 600 can improve the stability of the pallet 110 when suspended.

[0045] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the battery is placed inside the limiting groove 120, and then the electrode tab is attached to the top of the pad 130. Then, the hydraulic cylinder 230 is activated, and the heat sealing plate 210 cooperates with the pad 130 to achieve heat sealing of the electrode tab. After that, during the unloading process, the movable end of the control cylinder 330 is retracted, and then the lifting plate 340 rises. Then, the lifting plate 340 rises against the T-shaped column 310 and the roller 320. Since the lengths of the multiple T-shaped columns 310 are not equal, the battery lifted by the multiple rollers 320 is placed at an angle. Then, under the action of weight, the battery slides down and falls into the receiving box 700 from the slope position, achieving the purpose of unified collection, eliminating manual unloading and improving unloading safety.

[0046] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
