Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery processing, and in particular to an automatic feeding system and feeding method for lithium battery processing trays. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. In 1912, lithium metal batteries were first proposed and studied by Gilbert N. Lewis. In the 1970s, MS Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream.

[0003] In the prior art, such as the Chinese patent number: CN114435899B "A lithium battery processing tray automatic feeding system", includes a base plate, a support frame is installed on the base plate, a conveyor belt is rotatably connected to the support frame, a driving mechanism for driving the conveyor belt is provided on the base plate, a lithium battery tray is placed on the conveyor belt, a plurality of lithium battery bodies are arranged and installed on the lithium battery tray, a fixing mechanism for limiting and fixing the lithium battery tray is provided on one side of the support frame, a U-shaped plate is connected to one side of the base plate through a moving mechanism, a mounting plate is connected to the U-shaped plate through a pushing mechanism, and a detection mechanism for detecting the gap between the lithium battery body and the lithium battery tray is provided on the mounting plate. The beneficial effect is that when the mounting plate moves toward the inside of the lithium battery body and there is a gap between the lithium battery body and the lithium battery tray, the cam is driven to push the sealing plate. Through the push of the sealing plate, the marking liquid inside the storage box can pass through the operating box and flow out from the discharge pipe. The lithium battery body with a gap during the detection process is marked and identified by the flowing marking liquid, thereby forming a detection and identification mechanism during the use of the automatic input device, which is convenient for judging whether there is a gap between each lithium battery body on the lithium battery tray and the lithium battery tray, thereby further improving the quality of lithium battery processing.

[0004] However, in the prior art, the tray cannot be accurately placed on the horizontal line of the welding equipment, so that the lithium batteries on the tray cannot be welded to the conductive plate, which may lead to welding failure, resulting in rework or even scrapping.

[0036] The present invention also discloses a method for automatically feeding a lithium battery processing tray into a system, which comprises the following steps:

[0037] S1: Place the pallet body on the conveyor belt, then start the motor to drive the driving wheel to rotate, the driving wheel will drive the conveyor roller to rotate through the belt and the driven wheel, and the rotation of the conveyor roller will drive the pallet body located above the conveyor belt to move;

[0038] S2: When the position sensor detects that the tray body moves to the middle of the two transmission shafts, the position sensor will control the motor to turn off, and at the same time control the cylinder to push the push rod to move outward. During the movement, the push rod will also drive the rack to move synchronously;

[0039] S3: The movement of the rack will drive a transmission shaft connected to it to rotate through meshing with gear 1. Since gears 2 on the top of the two transmission shafts mesh with each other, the two transmission shafts will rotate in opposite directions, and then the two deviation-correcting components will be driven to approach the two sides of the pallet body through the lateral adjustment component, the connecting component and the longitudinal adjustment component. When the two deviation-correcting components are in a parallel state, the position of the pallet body will eventually be limited to the central axis of the conveyor belt, so that it remains within the working range of the welding equipment;

[0040] S4: When the two deflection correcting components approach the pallet body, the sliding roller in the deflection correcting component first contacts the pallet body. Since the sliding roller is rotatably connected to the deflection correcting plate, the side wall of the pallet body slides on the side wall of the deflection correcting plate, so that the skewed pallet body is finally straightened;

[0041] S5: After the position of the pallet body is corrected, the cylinder drives the push rod and the rack to retract together, and the rack drives a transmission shaft connected to it to rotate in the opposite direction through meshing with the gear 1, and again through the mutual meshing of the two gears 2, the two transmission shafts drive the two deviation correction components away from the pallet body through the lateral adjustment component, the connecting component and the longitudinal adjustment component;

[0042] S6: When the two deviation-correcting components are away from the top of the conveyor belt, the motor will start again to drive the conveyor belt to operate, and transport the pallet body to the bottom of the welding equipment for welding;

[0043] S7: When the size of the pallet body changes or the position of the welding equipment is displaced, and the position of the pallet body needs to be limited again, rotating the screw rod 1 can adjust the distance between the connecting arm and the transverse arm, thereby adjusting the distance between the two fixed blocks to adapt to pallet bodies of different sizes. Rotating the screw rod 2 can adjust the distance between the connecting arm and the longitudinal arm, thereby ensuring that the fixed block is always kept on the same horizontal line with the welding equipment, so that the pallet body is always within the working range of the welding equipment after correction.

[0044] Compared with the prior art, the present invention has the following beneficial effects:

[0045] 1. In the present invention, the cooperation between the driving mechanism and the battery body can correct the position of the tray body that is not within the working range of the welding equipment, thereby ensuring that the tray body will not be welded incorrectly when it is moved to the bottom of the welding equipment for welding, thereby reducing production losses;

[0046] 2. In the present invention, the setting of the sliding roller can reduce the damage caused by the direct collision between the pallet body and the correction plate, and at the same time make the correction process of the pallet body smoother. When the specifications of the pallet body are small, the collision damage caused by the collision can also be reduced by setting the buffer pad;

[0047] 3. In the present invention, rotating screw rod 1 can adjust the distance between the connecting arm and the transverse arm, thereby adjusting the distance between the two fixed blocks, so that it can adapt to pallet bodies of different sizes. Rotating screw rod 2 can adjust the distance between the connecting arm and the longitudinal arm, thereby ensuring that the fixed block is always kept on the same horizontal line with the welding equipment, so that the pallet body is always located within the working range of the welding equipment after correction.

2. A method for automatically feeding a lithium battery processing tray into a system, using the automatic feeding system for lithium battery processing trays as claimed in claim 1, characterized in that: The following steps are involved: S1: placing the pallet body (2) above the conveyor belt (13), and then starting the motor (15) to drive the driving wheel (16) to rotate. The driving wheel (16) drives the conveyor roller (12) to rotate through the belt (18) and the driven wheel (17). The rotation of the conveyor roller (12) drives the pallet body (2) above the conveyor belt (13) to move; S2: When the position sensor detects that the tray body (2) moves to the middle of the two transmission shafts (45), the position sensor controls the motor (15) to turn off, and at the same time controls the cylinder (42) to push the push rod (43) to move outward, and the push rod (43) also drives the rack (44) to move synchronously during the movement; S3: The movement of the rack (44) will drive a transmission shaft (45) connected thereto to rotate by meshing with the gear 1 (46). Since the gear 2 (47) on the top of the two transmission shafts (45) mesh with each other, the two transmission shafts (45) will rotate in opposite directions, and then drive the two deviation correcting components (54) to approach the two sides of the pallet body (2) through the lateral adjustment component (51), the connecting component (52) and the longitudinal adjustment component (53). When the two deviation correcting components (54) are in a parallel state, the position of the pallet body (2) will eventually be limited to the central axis of the conveyor belt (13), so that it remains within the working range of the welding equipment; S4: When the two deflection correcting assemblies (54) approach the pallet body (2), the sliding roller (543) in the deflection correcting assemblies (54) first contacts the pallet body (2). Since the sliding roller (543) is rotatably connected to the deflection correcting plate (541), the side wall of the pallet body (2) slides on the side wall of the deflection correcting plate (541), so that the skewed pallet body (2) is finally straightened; S5: After the position of the pallet body (2) is corrected, the cylinder (42) drives the push rod (43) and the rack (44) to retract together, and the rack (44) drives a transmission shaft (45) connected thereto to rotate in the opposite direction through meshing with the gear 1 (46), and again through the mutual meshing of the two gears 2 (47), the two transmission shafts (45) drive the two deviation correction components (54) away from the pallet body (2) through the lateral adjustment component (51), the connection component (52) and the longitudinal adjustment component (53); S6: When the two deviation-correcting components (54) are away from the top of the conveyor belt (13), the motor (15) is started again to drive the conveyor belt (13) to operate, and the tray body (2) is transported to the bottom of the welding equipment for welding; S7: When the size of the tray body (2) changes or the position of the welding equipment is displaced, and the position of the tray body (2) needs to be limited again, the rotation of the screw rod 1 (516) can adjust the distance between the connecting arm (521) and the transverse arm (512), thereby adjusting the distance between the two fixing blocks (514) so ​​that it can adapt to tray bodies (2) of different sizes. The rotation of the screw rod 2 (534) can adjust the distance between the connecting arm (521) and the longitudinal arm (531), thereby ensuring that the fixing block (514) is always kept on the same horizontal line with the welding equipment, so that the tray body (2) is always located within the working range of the welding equipment after correction.
