Description

Technical Field

[0001] The invention belongs to the technical field of battery manufacturing, and in particular relates to a steel ball dispensing machine. Background Art

[0002] See also Figure 1 During the battery manufacturing process, after the secondary liquid injection is completed, a sealing nail or a steel ball 20 needs to be immediately driven into the liquid injection hole 13 of the aluminum top cover 10 to seal the liquid injection hole 13. For driving the steel ball 20, it is required that the steel ball 20 and the liquid injection hole 13 have an interference fit, and the steel ball 20 is embedded in a preset position on the wall of the liquid injection hole 13, and the distance from the steel ball 20 to the bottom surface A of the liquid injection port 11 reaches a preset value. Figure 1 The specific requirements for hitting the steel ball 20 in the injection hole 13 of a square aluminum shell battery are as follows: the diameter 2r of the steel ball 20 is 3.05±0.02mm, the steel ball 20 is embedded in the upper and lower center position of the injection hole 13 wall, and the height H of the steel ball 20 protruding from the bottom surface A of the injection port 11 is 0.52±0.05mm, and it must not be biased upward or downward. Because the steel ball 20 biased upward will lift up the sealing nail cover plate to be welded later, and in serious cases, it may cause the steel ball 20 to loosen or even fall into the battery and fall on the battery cell. The steel ball 20 falling on the battery cell will overlap the cathode and anode sheets to cause an internal short circuit in the battery, which will inevitably cause the battery to explode. The steel ball 20 biased downward is a safety hazard for the battery, so the quality of hitting the steel ball 20 is very important.

The steel ball hitting device 200 of this solution can realize automatic and accurate steel ball hitting operation.

[0088] In this embodiment, the steel ball dispensing machine includes at least two steel ball devices 200, see Figure 3 The feeding and transporting device 400 includes a transporting support 410, a steel ball beating transporting robot 420 and a cleaning feeding robot 430. The steel ball beating transporting robot 420 and the cleaning feeding robot 430 are respectively movably connected to the transporting support 410; the steel ball beating transporting robot 420 can be moved between the feeding device 100 and any one of the steel ball beating devices 200 to transport the battery to one of the vacant steel ball beating devices 200; the cleaning feeding robot 430 can be moved between any one of the steel ball beating devices 200 and the cleaning device 300 to output the battery on one of the steel ball beating devices 200 carrying the battery to the cleaning device 300;

[0089] Among them, when the steel ball hitting transfer robot 420 moves, the steel ball hitting device 200 carrying batteries is in the steel ball hitting operation or the battery is grabbed by the cleaning feeding robot 430 for discharging operation. When the cleaning feeding robot 430 moves, the steel ball hitting device 200 carrying batteries is in the steel ball hitting operation or the battery is grabbed by the steel ball hitting transfer robot 420 for feeding operation.

[0090] The operation process of the feed transfer device 400 is as follows:

[0091] Initial state: the steel ball punching transfer robot 420 is stopped at the feeding belt of the feeding device 100, and the cleaning feeding robot 430 is stopped at the second steel ball punching device 200;

[0092] Step 1: The steel ball punching transfer robot 420 grabs the liquid-filled battery from the feeding belt of the feeding device 100 and moves it to the first steel ball punching device 200, and at the same time, the cleaning feeding robot 430 moves to the side of the first steel ball punching device 200 facing the second steel ball punching device 200;

[0093] Step 2: The steel ball punching transfer robot 420 is reset to the feeding belt of the feeding device 100 to continue to grab the liquid-filled batteries. After the first steel ball punching device 200 has been operated and is ready to be discharged, and the second steel ball punching device 200 is ready to be loaded, the cleaning feeding robot 430 moves to the first steel ball punching device 200 to grab the steel ball punched batteries and moves toward the cleaning device 300;

[0094] Step 3: The steel ball punching transfer robot 420 grabs the liquid-filled battery and moves toward the second steel ball punching device 200, and the cleaning feeding robot 430 moves into the cleaning device 300 to unload the steel ball punched battery;

[0095] Step 4: The steel ball punching transfer robot 420 grabs the liquid-filled battery and moves it to the second steel ball punching device 200, and the cleaning feeding robot 430 moves to the side of the second steel ball punching device 200 that is away from the first steel ball punching device 200;

[0096] Step 5: The steel ball punching transfer robot 420 moves back to the feeding belt of the feeding device 100, and when the second steel ball punching device 200 has finished working and is ready to discharge, the cleaning feeding robot 430 moves into the second steel ball punching device 200 to grab the steel ball punched battery, and then moves to the cleaning device 300;

[0097] Step 6: The steel ball punching transfer robot 420 is reset to the feeding belt of the feeding device 100 to continue to grab the liquid-filled batteries, and the cleaning feeding robot 430 moves toward the first steel ball punching device 200;

[0098] Repeat steps 1 to 6.

[0099] In other embodiments, when the steel ball punching transfer robot 420 first loads the batteries of the two steel ball punching devices 200 and then drives the cleaning feeding robot 430 to grab the unloaded materials, the initial position of the cleaning feeding robot 430 is modified accordingly (if it is set on the same transfer bracket 410);

[0100] Step 1: When the second steel ball punching device 200 has just finished loading the battery, the steel ball punching transfer robot 420 returns to the feeding belt of the feeding device 100 to continue grabbing the liquid-filled battery and then feeds it to the first steel ball punching device 200. At the same time, the cleaning feeding robot 430 moves to the first steel ball punching device 200 to grab the steel ball punched battery and move it to the cleaning device 300.

[0101] Step 2: The cleaning feeding robot 430 then returns to the second steel ball punching device 200 to grab the steel ball punched battery and move it to the cleaning device 300. At the same time, the steel ball punching transfer robot 420 returns to grab the liquid-filled battery.

[0102] Then repeat the first step to the second step.

[0103] Through the mutual cooperation between the feeding and transferring device 400 and the multiple steel ball hitting devices 200, it is possible to achieve that when one steel ball hitting device 200 is hitting steel balls, another steel ball hitting device 200 is loading and unloading materials, so that the cleaning device 300 and the glue dispensing and curing device 500 can operate uninterruptedly, thereby improving work efficiency.

[0104] Specifically, when there are two steel ball hitting devices 200, the steel ball hitting transfer robot 420 and the cleaning feeding robot 430 can be set on the same transfer bracket 410 (to reduce manufacturing costs), or they can be respectively set on two transfer brackets 410 to reduce interference between the steel ball hitting transfer robot 420 and the cleaning feeding robot 430 and improve work efficiency; when there are more than two steel ball hitting devices 200, the steel ball hitting transfer robot 420 and the cleaning feeding robot 430 can be respectively set on two transfer brackets 410 to reduce interference between the steel ball hitting transfer robot 420 and the cleaning feeding robot 430 and improve work efficiency.

[0107] The steel ball punching transfer robot 420 and the cleaning feed robot 430 of the feed transfer device 400 both place the battery from top to bottom and take the battery from bottom to top. A battery clamping space is formed between the work handling fixed clamp 2123 and the work handling movable clamp 2125 of the work handling fixture 212 to facilitate the taking and placing of the battery. The transport direction of the work handling drive component 211 is intersected with (preferably perpendicular to) the transport direction of the feed transfer device 400, so that the movement of the work handling drive component 211 and the movement of the feed transfer device 400 do not interfere with each other, and the two can move at the same time, realizing the cooperation of multiple work handling fixtures 212 and the feed transfer device 400, and improving the efficiency of steel ball punching.
