[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] As Figures 1 to 3 shown, a fully automatic lithium battery dryer includes a plurality of drying cavities 1 and a cavity stepping mechanism 2. The cavity stepping mechanism 2 includes a main body frame 21, a mounting rod 22 and a docking cylinder 23. A placement cavity 211 is provided in the main body frame 21, and the placement cavities 211 are distributed in a linear array. A conveying section 3 is provided in each placement cavity 211. The mounting rod 22 is fixed on the outside of the main body frame 21, and the docking cylinder 23 is fixed on the mounting rod 22. A power supply connector 24, a vacuum connector 25 and a nitrogen connector 26 are connected to the driving end of the docking cylinder 23. It further includes a cavity positioning mechanism 4. The cavity positioning mechanism 4 is provided in the placement cavity 211 and directly above the conveying section 3. The cavity positioning mechanism 4 is used to position the drying cavity 1 on the conveying section 3 so that the docking cylinder 23 can drive the power supply connector 24, the vacuum connector 25 and the nitrogen connector 26 to be successfully docked with the drying cavity 1.

[0026] When the conveying section 3 in the placement cavity 211 drives the drying cavity 1 to move to a position corresponding to the docking cylinder 23, the cavity positioning mechanism 4 positions the drying cavity 1 to correct the angular orientation and position of the drying cavity 1. Then, the docking cylinder 23 drives the power supply connector 24, the vacuum connector 25 and the nitrogen connector 26 to be docked with the drying cavity 1 for drying treatment. When the battery is dried, the docking cylinder 23 drives the power supply connector 24, the vacuum connector 25 and the nitrogen connector 26 to leave the drying cavity 1, and the cavity positioning mechanism 4 releases the positioning of the drying cavity 1.

[0027] The cavity positioning mechanism 4 positions the drying cavity 1 to eliminate the alignment deviation between it and the power supply connector 24, the vacuum connector 25 and the nitrogen connector 26, so that the power supply connector 24, the vacuum connector 25 and the nitrogen connector 26 are aligned with the corresponding interfaces of the drying cavity 1 and finally successfully docked with the drying cavity 1.

[0028] As Figure 4As shown, the cavity positioning mechanism 4 includes a substrate 41, a driving assembly 42, and a jaw assembly. The driving assembly 42 is installed under the substrate 41. The jaw assembly is slidably connected under the substrate 41 and is drivingly connected to the driving assembly 42. The driving assembly 42 drives the jaw assembly to perform centripetal or centrifugal motion.

[0029] As Figure 4 shown, the driving assembly 42 includes a power module 421, mirror-image traction modules 423, and mirror-image transmission modules 422. The power module 421 is hinged to the mirror-image transmission modules 422. The mirror-image transmission modules 422 are fixedly connected to the mirror-image traction modules 423 respectively. The mirror-image traction modules 423 are all hinged to the jaw assembly. The power module 421 drives the mirror-image transmission modules 422 to drive the mirror-image traction modules 423 to drive the jaw assembly to perform centripetal or centrifugal motion.

[0030] When the cavity positioning mechanism 4 positions the drying cavity 1, the power module 421 drives the mirror-image transmission modules 422 to drive the mirror-image traction modules 423 to drive the jaw assembly to perform centripetal motion, so as to clamp the side surface at the outer corner of the drying cavity 1, realizing the correction of the angular orientation and position of the drying cavity 1.

[0031] As Figure 5 shown, the power module 421 includes mirror-image cylinders 4211 and hinge members 4212. The opposite ends of the mirror-image hinge members 4212 are fixedly connected to the output ends of the mirror-image cylinders 4211 respectively. The opposite ends of the mirror-image hinge members 4212 are hinged to the mirror-image transmission modules 422 respectively. The mirror-image cylinders 4211 drive the mirror-image hinge members 4212 to move towards or away from each other respectively. The mirror-image hinge members 4212 drive the mirror-image traction modules 423 to drive the jaw assembly to perform centripetal or centrifugal motion respectively through the mirror-image transmission modules 422.

[0032] As Figure 6 shown, when the mirror-image cylinders 4211 drive the mirror-image hinge members 4212 to move towards each other, the mirror-image hinge members 4212 drive the mirror-image traction modules 423 to drive the jaw assembly to perform centripetal motion respectively through the mirror-image transmission modules 422.

[0033] As Figure 6As shown in the figure, the transmission module 422 includes a lever 4221, a hinge seat 4222, a universal hinge unit 4223, a transmission shaft 4224, a shaft support 4225, and a T-shaped output connecting member 4226. One end of the lever 4221 is hinged to the output end of the power module 421 by a first hinge shaft, and the other end of the lever 4221 is hinged to the hinge seat 4222 by a second hinge shaft. The universal hinge unit 4223 is hinged to the lever 4221 by a third hinge shaft. The center distance between the third hinge shaft and the first hinge shaft is greater than the center distance between the third hinge shaft and the second hinge shaft. One end of the transmission shaft 4224 is fixedly connected to the universal hinge unit 4223. The transmission shaft 4224 passes through the shaft support 4225 and is slidably connected to the shaft support 4225. The other end of the transmission shaft 4224 is fixedly connected to the traction module 423 through the output connecting member 4226.

[0034] As Figure 6 shown in the figure, when the power module 421 drives the transmission module 422 to move, the power module 421 drives the first hinge shaft to drive the lever 4221 to rotate around the axis of the second hinge shaft, so that it drives the universal hinge unit 4223 to drive the transmission shaft 4224 to link the output connecting member 4226 to move along the Y-axis direction. By using the principle of the lever to drive the transmission shaft 4224, the power module 421 with a small output force can achieve the effect of a large output force. The power module 421 with a small output force has a lower cost, which can save costs.

[0035] One end of the lever 4221 is provided with a concave hinge joint, and a long hole is opened in the concave hinge joint and penetrates along the Z-axis direction. The long hole is hinged to the output end of the power module 421 by a first hinge shaft. By setting the long hole, there is a movement margin between the concave hinge joint and the first hinge shaft, so that the first hinge shaft can smoothly drive the concave hinge joint to link the lever 4221 to rotate around the axis of the second hinge shaft.

[0036] The universal hinge unit 4223 includes a ball hinge structure and a hinge seat structure. The ball hinge structure is fixedly connected to one end of the transmission shaft 4224. The hinge seat structure is installed on the ball hinge structure and is hinged to the lever 4221 by a third hinge shaft.

[0037] As Figure 6 shown in the figure, the ball hinge structure includes a sphere, and a first ball hinge seat 4223-11 and a second ball hinge seat 4223-12 which are arranged in a split manner. Hemispherical grooves 4223-111 and 4223-121 are respectively opened on the opposite sides of the first ball hinge seat 4223-11 and the second ball hinge seat 4223-12. The first ball hinge seat 4223-11 is fixedly connected to the second ball hinge seat 4223-12. The hemispherical groove 4223-111 and the hemispherical groove 4223-121 cooperate to form a sphere receiving groove. The sphere receiving groove has an opening, and the diameter of the opening is smaller than the diameter of the sphere. The sphere is installed at one end of the transmission shaft 4224 and is rotatably connected to the sphere receiving groove.

[0038] As Figure 6As shown in the figure, the hinge seat structure includes hinge block one 4223-21 and hinge block two 4223-22. Hinge block one 4223-21 and hinge block two 4223-22 are arranged oppositely and are respectively fixedly connected to ball hinge seat one 4223-11 and ball hinge seat two 4223-12. Both ends of hinge shaft one are respectively inserted into hinge block one 4223-21 and hinge block two 4223-22. Hinge shaft one passes through lever 4221, and lever 4221 is located between hinge block one 4223-21 and hinge block two 4223-22.

[0039] As Figure 6 shown in the figure, the traction module 423 includes a transverse rod 4231 and traction rods 4232 arranged in mirror image. The transverse rod 4231 is fixedly connected to the transmission module 422. One ends of the traction rods 4232 arranged in mirror image are respectively hinged to both ends of the transverse rod 4231 through hinge shaft four. The other ends of the traction rods 4232 arranged in mirror image are respectively hinged to the jaw assembly through hinge shaft five.

[0040] As Figure 6 shown in the figure, when the transmission module 422 drives the traction module 423 to move, the transmission module 422 drives the transverse rod 4231 to move along the Y axis, and it drives the jaw assembly to move through hinge shaft four, traction rod 4232 and hinge shaft five in sequence.

[0041] As Figure 4 shown in the figure, the jaw assembly includes four groups of movable jaws 43 arranged in mirror image. The four groups of movable jaws 43 arranged in mirror image are distributed at the four corner positions of the substrate 41. The movable jaw 43 includes an L-shaped seat 431 and roller shaft modules 432 arranged in mirror image. The L-shaped seat 431 is slidably connected under the substrate 41. The roller shaft modules 432 arranged in mirror image are installed on the L-shaped seat 431. A V-shaped opening is formed between the roller shaft modules 432 arranged in mirror image.

[0042] As Figure 6 shown in the figure, when the traction module 423 drives the jaw assembly to perform a centripetal movement, the traction assembly drives the four groups of L-shaped seats 431 to perform a centripetal movement. Each group of L-shaped seats 431 drives the two groups of roller shaft modules 432 to fit against the adjacent sides at the corner of the drying cavity 1. At this time, the corner of the drying cavity 1 is located in the V-shaped opening.

[0043] As Figure 4 shown in the figure, the roller shaft module 432 includes a Z-axis roller shaft 4321 and a roller shaft bracket 4322. The Z-axis roller shaft 4321 is installed on the roller shaft bracket 4322. An equilateral triangular body extending in the up and down direction is provided on the L-shaped seat 431. The roller shaft bracket 4322 is installed on the inclined surface of the equilateral triangular body.

[0044] The above does not impose any limitation on the technical scope of the present invention. Any modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
