[0002] Lithium-ion batteries, commonly known as rocking chair batteries, are a general term for batteries with lithium-ion embedded compounds as positive electrode materials. They are secondary batteries that mainly rely on the movement of lithium ions between the positive and negative electrodes to work. According to the different electrolyte materials used in lithium-ion batteries, lithium-ion batteries are divided into liquid lithium-ion batteries and polymer lithium-ion batteries. Lithium-ion batteries have the characteristics of high energy density, high average output voltage and low self-discharge. In the manufacturing process of lithium-ion batteries, packaging equipment is often required to process them, but the existing lithium-ion battery packaging equipment has some shortcomings, such as:

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] Embodiment 1:

[0033] In order to solve the problem that it is difficult to detect the pressure when the lithium-ion battery is packaged in the prior art, the following solution is disclosed. Figure 1-6 The utility model provides a technical solution: a packaging device, comprising an operating table 1, and a limiting seat 2 arranged on the top of the operating table 1, the limiting seat 2 is arranged on the top of the operating table 1, and a supporting plate 3 is arranged on the top of the limiting seat 2, and the top of the supporting plate 3 is connected to a lower sealing plate 4, and the four sides of the lower sealing plate 4 are fitted with the inner side of the limiting seat 2;

[0034] Two groups of connecting frames 5 are respectively provided on the left and right sides of the support plate 3, and the connecting frames 5 are connected to the connecting plates 6, and a pneumatic damper 7 is provided at the bottom of the connecting plates 6, and the bottom of the pneumatic damper 7 is connected to the operating platform 1; and the top of the operating platform 1 is connected to the gantry 8, and a cylinder 9 is provided on the top of the gantry 8, and the bottom of the cylinder 9 is connected to the hydraulic rod 10, and the hydraulic rod 10 is connected to the upper sealing plate 11;

[0035] When using the packaging equipment, first place the lithium-ion battery on top of the lower sealing plate 4, then start the cylinder 9, so that the cylinder 9 drives the hydraulic rod 10 to rise and fall, thereby pushing the upper sealing plate 11 to package the lithium-ion battery, and when the upper sealing plate 11 is pressed down, the lower sealing plate 4 and the support plate 3 will be driven by the pressure of the upper sealing plate 11 to drop, so that the lithium-ion battery is located inside the limit seat 2 for limit, and because the pneumatic damper 7 is connected to the support plate 3 through the connecting frame 5 and other equipment, when the lithium-ion battery is packaged, the pneumatic damper 7 will rebound to drive the support plate 3 and the lower sealing plate 4 to rise, so that the lithium-ion battery escapes from the limit seat 2;

[0036] A set of fixed seats is provided at the rear side of the operating table 1, and the fixed seats are connected to the telescopic rod 12, and the telescopic rod 12 is connected to the push plate 13, and the height of the push plate 13 is consistent with the height of the limit seat 2; a placement plate 14 is provided at the front of the limit seat 2, and a fixed shaft is provided on the left and right sides of the top of the placement plate 14, and the fixed shaft on the left is connected to two sets of gears 15, the gears 15 are meshed with each other, and an extrusion rod 16 is provided on the left side of the gear 15;

[0037] The upper sealing plate 11 can form a seal with the inner side of the limiting seat 2, and the upper sealing plate 11 and the fitting surface of the lower sealing plate 4 are opposite; two groups of slots are respectively provided on the left and right sides of the limiting seat 2, and the connecting frame 5 passes through the slots on both sides of the limiting seat 2 to connect with the connecting plate 6;

[0038] When the lithium-ion battery is packaged, the telescopic rod 12 can be started to drive the push plate 13 to move, so that the push plate 13 pushes the lithium-ion battery to the placement plate 14. When the lithium-ion battery passes through the extrusion rod 16, the extrusion rod 16 rotates due to the fit with the lithium-ion battery. Since the two sets of gears 15 are connected to each other, when one set of extrusion rods 16 rotates, the other set of extrusion rods 16 will also rotate accordingly, so that the two sets of extrusion rods 16 can squeeze the lithium-ion battery at the same time to complete the secondary packaging.

[0039] Embodiment 2:

[0040] In this embodiment, a method for checking pressure is disclosed, which is different from the first embodiment. Figure 4-5 As shown, the difference between this embodiment and embodiment 1 is that: a vent pipe 17 is provided at the front of the limit seat 2, and the vent pipe 17 is connected to the air collecting box 18, and the air collecting box 18 is connected to the operating table 1; a pressure gauge 19 is provided on the front side of the air collecting box 18, and the pressure gauge 19 is connected to the air collecting box 18, and the pressure gauge 19 is connected to the pneumatic damper 7.

[0041] Working principle: When using the packaging equipment, first place the lithium-ion battery on the top of the lower sealing plate 4, then start the cylinder 9, so that the cylinder 9 drives the hydraulic rod 10 to rise and fall, thereby pushing the upper sealing plate 11 to package the lithium-ion battery, and when the upper sealing plate 11 is pressed down, the lower sealing plate 4 and the support plate 3 will be driven down by the pressure of the upper sealing plate 11, so that the lithium-ion battery is located inside the limit seat 2 for limit, and because the pneumatic damper 7 is connected to the support plate 3 through the connecting frame 5 and other equipment, when the lithium-ion battery is packaged, the pneumatic damper 7 will rebound to drive the support plate 3 and the lower sealing plate 4 to rise, so that the lithium-ion battery escapes from the limit seat 2;

[0042] When the lithium-ion battery is packaged, the telescopic rod 12 can be started to drive the push plate 13 to move, so that the push plate 13 pushes the lithium-ion battery to the placement plate 14. When the lithium-ion battery passes through the extrusion rod 16, the extrusion rod 16 rotates due to the fit with the lithium-ion battery. Since the two sets of gears 15 are connected to each other, when one set of extrusion rods 16 rotates, the other set of extrusion rods 16 will also rotate accordingly, so that the two sets of extrusion rods 16 can squeeze the lithium-ion battery at the same time to complete the secondary packaging.
