DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figures 1 to 2The present invention provides a technical solution: a new energy battery tray stacking device, including a bracket 1, the bracket 1 is a rectangular frame structure, which is composed of a plurality of beams. A lifting mechanism 2 is arranged on both sides of the bottom upper surface of the bracket 1, and a clamping mechanism 3 is installed on the inner side of the lifting mechanism 2, which is characterized in that: the clamping mechanism 3 includes a clamping plate 31 and a telescopic component, the clamping plate moves back and forth under the drive of the telescopic component, the telescopic component is connected to the lifting mechanism, and two groups of upper and lower supporting plates 32 are installed on the inner end surface of the clamping plate 31. The supporting plate 32 is divided into an upper supporting plate 1 321 and a lower supporting plate 2 322. The supporting plate 32 is used to extend into the bracket provided on the side of the battery tray to lift the battery tray, and the distance from the supporting plate 1 321 to the upper wall of the battery tray bracket is less than or equal to the distance from the supporting plate 2 322 to the upper wall of the battery tray bracket. The end surface is provided with a support plate 32 arranged up and down, and at this time, the two battery material trays are stacked up and down, the upper support plate 1 321 is inserted into the bracket of the upper battery material tray, and the lower support plate 2 322 is inserted into the bracket of the lower battery material tray, and the distance from the upper support plate 321 to the upper wall of the battery material tray bracket is small, so that when the lifting mechanism is lifted, the support plate 1 321 touches the battery material tray first, and lifts the upper battery material tray first, and then the lifting mechanism continues to rise, and the support plate 2 322 will also lift the battery material tray subsequently, thereby achieving the effect of lifting the battery material trays in sequence, and using the lifting mechanism to lift two layers of battery material trays in sequence, reducing the position deviation of the battery material trays, improving the stacking accuracy between the battery material trays, and being able to control the stacking accuracy within 5mm, and avoiding a single row of support plates lifting multiple battery material trays, causing the bracket lifting part to be damaged by excessive force;

[0043] The clamping plate 31 is provided with a fine-adjusting mechanism to fine-adjust the position of the support plate 32. When the lifting mechanism 2 is installed on the bracket 1, when the lifting mechanisms on both sides move asynchronously, the fine-adjusting mechanism can be used to fine-adjust the position of the support plate 32 to adjust the holding position of the support plate 32. When the lifting mechanisms 2 on both sides move asynchronously, the position of the support plate 32 can be fine-adjusted to compensate for the lifting mechanisms 2 on both sides without disassembling the lifting mechanisms 2.

[0044] See also Figure 2 The fine-tuning mechanism includes a waist hole 311, which is provided on the support plate 32. A corresponding mounting hole is provided on the clamping plate 31 behind the waist hole 311. The support plate 32 is fixed to the clamping plate 31 by bolts passing through the fine-adjustable waist hole 311 and the mounting hole. An adjusting pad 323 is provided on the lower end surface of the support plate 32. The position of the support plate 32 is fine-tuned by moving the bolt up and down in the waist hole 311, so that the support plates 32 on the clamping plates 31 on both sides can move up and down synchronously, thereby avoiding errors in the installation of the lifting mechanisms 2 on both sides, which affect the clamping and lifting of the battery tray by the clamping mechanism 3;

[0045] The telescopic assembly includes a fixed plate 33 fixedly mounted on the lifting mechanism, a driving cylinder 34 is fixed on the fixed plate 33, the piston rod end of the driving cylinder 34 is fixedly connected to the clamping plate 31, a guide block 37 is fixed to the outer end surface of the fixed plate 33, and four guide rails 36 are fixedly mounted on the outer end surface of the clamping plate 31, and the guide rails 36 are slidably connected to the guide blocks 37. When clamping, the piston rod end of the driving cylinder 34 extends inward, thereby driving the clamping plate 31 to move inward. At this time, the guide rails 36 on the outer side of the clamping plate 31 will slide inside the guide blocks 37, so that the clamping plate 31 moves smoothly and stably inward to clamp the battery tray;

[0046] The clamping mechanism 3 also includes a mounting beam 38, which is fixed on the clamping plate 31, and the guide rail 36 is fixed on one end of the mounting beam 38. A limit plate 361 is fixedly installed at the end of the mounting beam 38, and the limit plate 361 limits the sliding of the guide block 37. The limit plate 361 is used to make the guide rail 36 slide inward, and the limit plate 361 interferes with the guide block 37. When the limit plate 361 moves to the position of the guide block 37, it will be stuck and cannot move inward. At the same time, the mounting beam improves the bearing capacity of the clamping plate, meeting the requirement that the clamping mechanism carries a large number of battery trays.

[0047] The lifting mechanism 2 includes two sets of slide rails 21 fixed on the inner end surface of the bracket 1, and the surface of the slide rails 21 is slidably connected with a slider 24, and a lifting frame 22 is fixed between the sliders 24. A mounting plate 23 is fixed on the inner end surface of the lifting frame 22, and a rack 25 is fixed on the mounting plate 23. A lifting motor 28 is fixedly installed on the upper end of the bottom of the bracket 1. The lifting motor 28 is connected to a lifting shaft 27 through a belt drive. The lifting shaft 27 is fixed to the bottom of the bracket 1 through a bearing connection. Gears 26 are connected to both ends of the lifting shaft 27. The gear 26 is meshed with the rack 25. The lifting motor 28 drives the lifting shaft 27 to rotate through a synchronous belt, so that the gears 26 at both ends of the lifting shaft 27 rotate, and the gear 26 is meshed with the rack 25. The gear 26 can drive the rack 25 to move up and down, and the rack 25 is fixed on the inner side of the lifting frame 22, pushing the lifting frame 22 to move up and down between the sliders 24, thereby realizing the lifting mechanism 2 to move up and down;

[0048] A roller transport mechanism 6 is fixedly installed above the bottom of the bracket 1. The roller transport mechanism 6 includes a transport frame 61 and a conveying roller 62 with sprockets at both ends. The conveying roller 62 is connected to the transport frame 61 by bearings. The conveying roller 62 is driven by a drive motor 65. The conveying roller 62 is driven by the drive motor 65, so that the battery material tray on the conveying roller 62 can be fed or unloaded, thereby realizing automatic transportation.

Figure 4 The fine-tuning mechanism includes a screw 312, a groove is provided on the side of the clamping plate 31, the screw 312 is fixed on the inner surface of the groove, the screw 312 passes through the support plate 32 and the aperture of the support plate 32 is larger than the diameter of the screw 312, and the lower end surface of the support plate 32 is affixed with a nut 313 engaged with the screw 312. By adjusting the position of the nut 313 on the screw 312, the position of the support plate 32 is controlled, so that the support plate 32 can compensate for the installation error of the lifting mechanism, thereby stably lifting the battery tray and avoiding the problem of uneven force on the battery tray caused by the lifting tilt and easy damage to the lifting point.

When there are only two layers of battery trays, the lower support plate 2 (322) will lift the upper battery tray to the upper station; When there are more than two layers of battery trays, the upper support plate 1 (321) will first lift the upper battery tray, and as the lifting mechanism (2) rises, the lower support plate 2 (322) will also subsequently lift the lower battery tray, so that the battery trays are lifted to the upper workstation in sequence, and the lifting mechanism (2) stops moving; S5, the roller transport mechanism (6) starts to operate again, transports the battery tray on the bottom layer to the disassembly station, and stops moving; S6, the lifting mechanism (2) starts to move downward to place the battery tray at the bottom, and stops moving. Then, the clamping mechanism (3) starts to reset and no longer clamps, completing the destacking and stopping moving.
