Description

Technical Field

[0001] This utility model relates to the field of storage battery production technology, and in particular to a battery clamping and flipping mechanism. Background Technology

[0002] During the lead welding process, the battery tabs are vertically downward. In order to allow the battery with welded tabs to be transported on the conveyor belt, a flipping mechanism is used to flip the battery so that the battery tabs are vertically upward. This prevents the battery tabs from being squeezed and facilitates subsequent operations such as cutting and tilting of the tabs.

[0003] Battery casings are usually quite brittle, especially lead-acid batteries. They should be handled with care when flipping them over, and should never be rolled or dropped to prevent the casing from cracking and causing electrolyte leakage or internal short circuits.

[0004] Existing battery flipping devices typically use two cylinders to clamp the battery casing via clamps. The two cylinders are fixed to a support, which is equipped with a motor. The motor drives the support to rotate, thereby rotating the battery held by the two cylinders and completing the battery flipping operation, ensuring that the battery tabs are vertically upward. However, during the battery flipping process, this structure is affected by the friction between the clamps and the battery casing. Occasionally, the battery may fall due to unstable clamping (such as when the battery casing surface is contaminated with water or other liquids, causing a decrease in the coefficient of friction of the battery casing). This can lead to production interruption and damage to the battery casing. Utility Model Content

[0005] The main purpose of this utility model is to provide a battery clamping and flipping mechanism. After the two clamping plates clamp and fix the battery, the adsorption device can adsorb and fix the battery, thereby further improving the stability of the battery when it is suspended in the air, preventing the battery from falling off during the flipping process, and ensuring the normal operation of the flipping process.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A battery clamping and flipping mechanism includes a frame, a rotating shaft rotatably connected to one side of the frame, a rotation drive device disposed on the other side of the frame, and a plurality of clamping components disposed within the frame. The plurality of clamping components include a first clamping mechanism and a second clamping mechanism disposed opposite to each other. The first clamping mechanism and the second clamping mechanism have the same structure and both include a linear drive device. A clamping plate is fixed to the drive end of the linear drive device, and an adsorption device for adsorbing and fixing the battery is disposed on the clamping plate.

[0008] Furthermore, the adsorption device includes a suction cup, a through groove is provided on the clamp, the suction cup is fixed in the through groove, and a vacuum pump is also included, with the suction cup connected to the vacuum pump through a pipe.

[0009] Further, the suction surface of the suction disc is in the same plane as the side of the battery clamped by the clamping plate.

[0010] Further, a rubber pad is glued to the side of the battery clamped by the clamping plate.

[0011] Further, the clamping plate clamping the side of the battery is fixed with a limiting plate at both ends.

[0012] Further, the side of the limiting plate in contact with the battery is provided with a guide slope.

[0013] Further, the rotary driving device comprises a servo motor and a gear box, the servo motor is connected with the gear box, and the output shaft of the gear box is fixedly connected with the frame body.

[0014] Further, the linear driving device is a gas cylinder, and the linear driving device is fixed on the frame body.

[0015] Compared with the prior art, the utility model has the beneficial effects that:

[0016] After the two clamping plates of the utility model clamp and fix the battery, the suction device can suction and fix the battery, so that the stability of the battery when it is suspended is further improved, the battery is prevented from falling during the overturning process, and the normal operation of the overturning process is ensured.

[0017] The two limiting plates of the utility model are in contact with the two sides of the battery respectively, so that the two clamping plates of a single clamping assembly clamp one battery.

[0018] The guide slope of the utility model can make the limiting plate more easily inserted into the gap between the two storage batteries, so as to separate the two storage batteries.

[0019] When the clamping plate of the utility model clamps the battery, the rubber pad can fully contact the battery, and after the clamping plate clamps the battery, the side of the battery contacted by the rubber pad should be in the same plane as the side of the suction disc, so that the suction disc can also suction and fix the battery.
