Description

Technical Field

[0001] The utility model relates to the technical field of waste discharge mechanisms, in particular to a waste discharge mechanism. Background Art

[0002] With the development of the new energy lithium battery industry, the stacking technology in the industry is constantly developing. Most cutting and stacking machines, thermal composite machines and other models adopt a multi-station stacking design. During the stacking process, there are usually detection equipment to detect whether the electrode sheets are good products. When defective products are detected, a waste discharge mechanism is required to screen out the defective products.

[0003] There are mostly three types of existing waste discharge schemes: the first is waste discharge above the vacuum belt, which uses a material-taking robot to grab the defective electrode and put it into the waste box above the belt. Such equipment occupies a large space and is relatively expensive. The robot needs to carry it back and forth for continuous waste discharge, which wastes stacking time and affects production efficiency; the second is waste discharge at the end of the vacuum belt, where the defective electrode is grabbed by the electrode-taking robot and falls into the waste box at the end of the conveyor belt. This waste discharge method cannot discharge waste continuously when multiple electrode sheets are defective or the electrode sheets at different stacking stations are defective, which affects the overall stacking efficiency; the third is waste discharge with an inverted belt, which hangs the vacuum chamber upside down so that there is suction under the belt. Normal electrode sheets will be transported normally when passing through the inverted belt. When the defective electrode sheets are on the inverted belt, the vacuum chamber will break the vacuum so that the belt has no suction, and the defective electrode sheets will be discharged into the waste box below. This waste discharge method is relatively expensive, and the inverted belt will change the distance between the electrode sheets, which will cause collisions and produce debris. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the utility model provides a waste discharge mechanism, which can solve the waste discharge cost problem, realize continuous waste discharge, and is easy to operate.

[0014] Furthermore, the lifting mechanism includes at least one hydraulic device, and an output end of the hydraulic device is connected below the secondary support frame.

[0015] By adopting the above solution, the secondary support frame can be lifted as a whole by the hydraulic device, so that a material discharge gap is reserved between the secondary conveying device and the main conveying device, thereby realizing material discharge to the waste collection device.

[0016] Furthermore, the lifting mechanism includes at least one hydraulic device, and the output end of the hydraulic device acts below the end of the secondary starting end transmission shaft.

[0017] By adopting the above scheme, the secondary starting end drive shaft of the secondary conveying device can be lifted by a hydraulic device, and the secondary conveying device rotates with the secondary ending end drive shaft as the center, thereby reserving a material unloading gap between the secondary conveying device and the main conveying device, thereby realizing material discharge to the waste collection device.

[0018] Furthermore, the hydraulic device is at least one of a pneumatic cylinder, a hydraulic rod and an oil cylinder.

[0019] By adopting the above solution, the lifting capability is achieved, the cost is low and the control is stable.

[0020] Furthermore, both ends of the secondary starting end transmission shaft are rotatably connected with guide plates.

[0022] Furthermore, the guide plate is arc-shaped.

The point end 12 is separated so that the electrode piece 6 falls into the waste collection device 7. The lifting mechanism 3 can be used to control the lifting of the secondary conveying device 2 so that the electrode piece 6 on the main transmission device falls into the waste collection device 7, and continuous waste discharge operation can be realized. By setting the main conveying device 1, the secondary conveying device 2 and the lifting mechanism 3, and connecting the secondary conveying device 2 with the main conveying device 1 end to end, continuous transportation and continuous waste discharge of the electrode piece 6 can be realized. When a defective electrode piece 6 is detected, the lifting mechanism 3 can control the secondary conveying device 2 to lift or rotate, so that a gap is formed between the main conveying device 1 and the secondary conveying device 2, so that the defective electrode piece 6 falls into the waste collection device 7 through the gap, saving equipment space, and at the same time solving the problem of multi-station waste discharge or continuous waste discharge, thereby improving waste discharge efficiency.

The main conveyor belt 14 is wound around the two main transmission shafts 13, and the main conveyor belt 14 is parallel to the horizontal plane, and is used to transport the pole pieces 6 for the cutting and stacking machine. The main transmission shaft 13 is rotatably connected to the main support frame 15, so that the main support frame 15 supports the main transmission shaft 13 without delaying the main transmission shaft 13 being driven by the motor to achieve the transmission effect, thereby completing the transportation effect of the pole piece 6. The secondary conveying device 2 includes a secondary starting end transmission shaft 23, a secondary end end rotating shaft 24, a secondary conveyor belt 25 and a secondary support frame 26, the secondary conveyor belt 25 is wound around the secondary starting end transmission shaft 23 and the secondary end end rotating shaft 24, the secondary starting end transmission shaft 23 is in contact with the secondary support frame 26, and the secondary end end rotating shaft 24 is in contact with the secondary support frame 26. Specifically, the lifting mechanism 3 includes at least one hydraulic device 4, the output end of the hydraulic device 4 is connected to the bottom of the secondary support frame 26 to ensure that the secondary conveying device 2 supported by the secondary support frame 26 maintains horizontal lifting, and the secondary support frame 26 is lifted as a whole by the hydraulic device 4, so that a material unloading gap is reserved between the secondary conveying device 2 and the main conveying device 1, so as to realize material discharge to the waste collection device 7.

[0043] It should be noted that the hydraulic device 4 is at least one of a pneumatic cylinder, a hydraulic rod and an oil cylinder, and the pneumatic cylinder, the hydraulic rod and the oil cylinder have lifting capabilities, low costs and stable control.

[0044] In Example 3, see Figure 6-7As shown, the main conveying device 1 includes a main transmission shaft 13, a main conveyor belt 14 and a main support frame 15. The main conveyor belt 14 is wound around the two main transmission shafts 13, and the main conveyor belt 14 is parallel to the horizontal plane, and is used to transport the pole pieces 6 for the cutting and stacking machine. The main transmission shaft 13 is rotatably connected to the main support frame 15, so that the main support frame 15 supports the main transmission shaft 13 without delaying the main transmission shaft 13 being driven by the motor to achieve the transmission effect, thereby completing the transportation effect of the pole piece 6. The secondary conveying device 2 includes a secondary starting end transmission shaft 23, a secondary end end rotating shaft 24, a secondary conveyor belt 25 and a secondary support frame 26. The secondary conveyor belt 25 is wound around the secondary starting end transmission shaft 23 and the secondary end end rotating shaft 24. The secondary starting end transmission shaft 23 is in contact with the secondary support frame 26. The secondary end end rotating shaft 24 is rotatably connected with the secondary support frame 26, so that the secondary conveying device 2 can be lifted and lowered as a whole or only one end of the secondary starting end transmission shaft 23 can be lifted and lowered to complete the waste discharge operation.

The secondary conveying device 2 rotates with the secondary end end transmission shaft as the center of the circle, so that a material discharge gap is reserved between the secondary conveying device 2 and the main conveying device 1, so as to realize material discharge to the waste collection device 7.

[0045] It should be noted that the hydraulic device 4 is at least one of a pneumatic cylinder, a hydraulic rod and an oil cylinder, and the cylinder, the hydraulic rod and the oil cylinder have lifting capabilities, low cost and stable control; it should be noted that since the rotation angle of the secondary terminal end rotating shaft 24 is relatively small, the use of a pneumatic cylinder, a hydraulic rod and an oil cylinder can meet and achieve the effect of lifting the secondary starting end transmission shaft 23, so that the pole piece 6 can fall.

[0046] In Examples 1-3, see Figure 3 , Figure 5 and Figure 7 As shown, in order to prevent the process of the pole piece 6 falling to the waste collection device 7 from being affected by the speed of the main conveyor belt 14 of the main conveyor 1, guide plates 5 are rotatably connected to the two ends of the secondary starting end transmission shaft 23.
