Description

Technical Field

[0001] This invention relates to the field of sorting machine technology, specifically to a lithium-ion battery steel-cased weighing and sorting machine. Background Technology

[0002] The lithium-thionyl chloride battery steel casing weighing and sorting machine is an automatic sorting device mainly used for weighing and sorting lithium-thionyl chloride battery steel casings. It typically consists of the following main parts: a feeding device, which places the lithium-ion battery casings to be sorted into the feeding device and feeds them into the sorting machine via a vibratory feeder or conveyor belt; a weighing device, an important component of the sorting machine, which uses high-precision weighing sensors and corresponding electronic equipment to weigh each lithium-ion battery casing and classify them into the corresponding sorting channel according to a set weight range; a sorting channel, which is used to sort the weighed lithium-ion battery casings to designated locations, and usually consists of multiple parallel chutes, each with a sensor to detect whether the chutes are full; a conveyor belt, which transports the sorted lithium-ion battery casings to designated locations, and can consist of one or more conveyor belts, with the speed and direction adjusted as needed; and a control system, the core of the sorting machine, which controls the entire sorting process through computer programs and sensors. It can automatically sort according to preset conditions and monitor the entire sorting process in real time to ensure accuracy and stability.

[0003] When existing sorting machines weigh and detect battery casings, there is a possibility that other objects may get stuck inside the battery casings. This would increase the weight of the battery casings during weighing, leading to missorting. Summary of the Invention

[0004] This invention provides the following technical solution:

[0005] A lithium-ion battery steel casing weighing and sorting machine includes a sorting box, the inside of which is provided with a conveyor belt for moving the battery steel casing on the sorting box.

[0006] The sorting box has sorting openings on both sides, and a baffle is provided at the entrance of the sorting opening. One end of the baffle is rotatably connected to the bottom of the inner wall of the sorting box, and a first motor is installed at the bottom of the baffle. The first motor is used to drive the baffle to rotate.

[0007] A weighing device is provided at one end of the sorting box, and a weighing pan is provided on the top of the weighing device;

[0008] A vision sensor is also installed above the weighing pan;

[0009] The battery steel casing is weighed by a weighing pan. The first motor below the corresponding sorting port is controlled to rotate according to the weight of the battery steel casing. The first motor drives the corresponding baffle to rotate, so that battery steel casings of different weights are sorted to the corresponding sorting port, thereby achieving the effect of fast sorting.

[0010] A scraping mechanism is provided above the sorting box. The scraping mechanism includes a scraping plate, which is slidably connected to the top of the sorting box. A scraping rod is connected to the bottom of the scraping plate. The scraping rod forms an inclined angle with the top surface of the conveyor belt. The scraping rod is staggered at the bottom of the scraping plate.

[0011] Furthermore, by installing a visual sensor above the weighing pan, the volume of the battery casing can be determined, preventing the weighing pan from misjudging the weight of the battery casing due to other objects mixed in, thus avoiding sorting errors.

[0012] Preferably, a feeding box is provided on one side of the weighing device, a feeding hopper is provided on the top of the feeding box, and a discharge chute is installed at one end of the feeding box. The discharge chute is inclined and the bottom end of the discharge chute is aligned with the upper center of the weighing pan.

[0013] Preferably, a movable plate is provided below the weighing pan, and a support column is connected to the bottom center of the movable plate. The bottom end of the support column contacts the top surface of the weighing device. Both ends of the bottom of the movable plate are connected to a first spring, which is connected to an external power source through a power cord. A feeding plate is provided at the end of the weighing device near the sorting box, and the bottom end of the feeding plate faces upwards towards the end of the conveyor belt.

[0014] By setting an energized first spring, after the weighing pan has finished weighing the battery steel casing, the first spring on the right side of the movable plate is energized, causing the first spring to contract and tilt the movable plate towards the sorting box, so that the weighed battery steel casing slides from the unloading plate into the sorting box.

[0015] Preferably, the bottom of the sorting box is connected to a support leg, the end of the sorting box away from the weighing device is connected to a discharge plate, and the sorting box has a plurality of sorting ports, which are staggered and respectively opened on both sides of the sorting box.

[0016] Preferably, a support block is connected to the middle of the sorting box, the upper end of the support block is in contact with the upper inner wall of the conveyor belt, the support block is used to support the upper part of the conveyor belt, and drive rollers are provided at both ends of the conveyor belt. The two ends of the two drive rollers are rotatably connected to the inner wall of the sorting box, and the two drive rollers rotate synchronously under the drive of the conveyor belt. One end of one of the drive rollers is connected to a drive device.

[0017] Preferably, the first motor is fixedly installed at the bottom of the sorting box, and the top output end of the first motor is connected to a drive shaft. The top end of the drive shaft is fixedly connected to one end of the bottom of the baffle. The first motor can drive the drive shaft and the baffle to rotate. By driving the drive shaft to rotate, the drive shaft can further drive the baffle to rotate, so that the baffle can block the battery steel shell and let the battery steel shell fall to the corresponding sorting port.

[0018] Preferably, the bottom of the baffle is connected to bristles that can contact the top surface of the conveyor belt, and a cleaning groove is provided at the bottom of the inner wall of the sorting port. When the baffle is folded to be parallel to the side wall of the sorting box, the bristles are placed inside the cleaning groove.

[0019] Preferably, the bottom of the cleaning tank is provided with a through hole, and the bottom end of the through hole is connected to a negative pressure pump, which generates negative or positive pressure in the through hole and the cleaning tank;

[0020] By installing bristles at the bottom of the baffle, when the baffle is rotated by the first motor, the bristles can scrape the top surface of the conveyor belt, removing dust from the conveyor belt and keeping it clean, thus preventing contamination of the battery casing. Furthermore, a negative pressure pump first blows air into the cleaning tank, causing the dust on the surface of the bristles to be blown into the interior of the cleaning tank. Then, the negative pressure pump creates negative pressure inside the cleaning tank, adsorbing the dust in the cleaning tank to the outside of the sorting box, thereby achieving the cleaning effect.

[0021] Preferably, the bottom of the sorting box is provided with a through groove, and a scraper is installed inside the through groove. The two ends of the scraper are hinged to the inner wall of the through groove. A second spring is connected between one end of the scraper and the inner wall of the through groove. The second spring always causes the top of the scraper to press towards the conveyor belt.

[0022] The second spring generates tension, causing the scraper to constantly press towards the conveyor belt, thereby scraping away dust from the outer wall of the conveyor belt through the top of the scraper, further improving the cleaning power.

[0023] A PLC controller is installed inside the weighing device, and the weighing pan, vision sensor and first motor are all connected to the PLC controller via signals.

[0024] The scraping mechanism also includes a sliding block, which is disposed on the bottom inner wall of the scraping plate. The outer wall of the sorting box is provided with a sliding groove, and the sliding block is slidably connected to the sliding groove. The sliding groove has an inclined angle. One end of the scraping plate is provided with an open groove, and a cam is disposed inside the open groove. The cam is rotatably connected to the outer wall of the sorting box. The outer wall of the sorting box is also connected with a fixing plate. A third spring is connected between the fixing plate and the inner wall of the open groove. A second motor is fixedly installed on the outer end of the cam.

[0025] Compared with the prior art, the present invention provides a lithium-ion battery steel-cased weighing and sorting machine, which has the following advantages:

[0026] 1. This invention uses a weighing pan to weigh the battery casings. Based on the weight of the battery casings, the first motor below the corresponding sorting port is controlled to rotate, causing the first motor to drive the corresponding baffle to rotate. This allows battery casings of different weights to be sorted to the corresponding sorting ports, achieving a rapid sorting effect. By setting a vision sensor above the weighing pan, the volume of the battery casings can be determined, preventing the weighing pan from misjudging the weight of the battery casings due to other objects mixed in, thus avoiding sorting errors.

[0027] 2. The present invention provides an energized first spring. After the weighing pan has finished weighing the battery steel shell, the first spring on the right side of the movable plate is energized, causing the first spring to contract and the movable plate to tilt towards the sorting box, so that the weighed battery steel shell slides from the unloading plate into the sorting box.

[0028] 3. The present invention uses a second spring to generate tension, so that the scraper is always pressed towards the conveyor belt, thereby scraping away the dust on the outer wall of the conveyor belt through the top of the scraper, further improving the cleaning power.

[0029] 4. This invention provides a brush at the bottom of the baffle. When the baffle is rotated by the first motor, the brush can scrape the top surface of the conveyor belt to remove dust, keeping the conveyor belt clean and preventing the battery casing from being contaminated.

[0030] 5. This invention uses a negative pressure pump to first blow air into the cleaning tank, causing the dust on the brush bristles to be blown into the interior of the cleaning tank. Then, the negative pressure pump creates negative pressure in the cleaning tank, adsorbing the dust in the cleaning tank to the outside of the sorting box, thereby achieving the cleaning effect.

[0043] See Figure 1-11 This embodiment discloses a lithium-ion battery steel shell weighing and sorting machine, including a sorting box 100, and a conveyor belt 111 is provided inside the sorting box 100. The conveyor belt 111 is used to move the battery steel shell on the sorting box 100.

[0044] The sorting box 100 has sorting openings 101 on both sides. A baffle 104 is provided at the entrance of the sorting opening 101. One end of the baffle 104 is rotatably connected to the bottom of the inner wall of the sorting box 100. A first motor 109 is installed at the bottom of the baffle 104. The first motor 109 is used to drive the baffle 104 to rotate.

[0045] A weighing device 300 is provided at one end of the sorting box 100, and a weighing pan 302 is provided on the top of the weighing device 300.

[0046] A vision sensor 301 is also provided above the weighing pan 302;

[0047] The battery steel shell is weighed by the weighing pan 302. The first motor 109 below the corresponding sorting port 101 is controlled to rotate according to the weight of the battery steel shell. The first motor 109 drives the corresponding baffle 104 to rotate, so that battery steel shells of different weights are sorted to the corresponding sorting port 101, thereby achieving the effect of fast sorting.

[0048] Furthermore, by setting a vision sensor 301 above the weighing pan 302, the volume of the battery steel shell can be determined, avoiding misjudgment of the weight of the battery steel shell by the weighing pan 302 due to other objects mixed in inside the battery steel shell, thus avoiding sorting errors.

[0049] A scraping mechanism 400 is provided above the sorting box 100. The scraping mechanism 400 includes a scraping plate 401, which is slidably connected to the top of the sorting box 100. A scraping rod 402 is connected to the bottom of the scraping plate 401. The scraping rod 402 forms an inclined angle with the top surface of the conveyor belt 111. The scraping rod 402 is staggered at the bottom of the scraping plate 401.

[0050] As one possible embodiment, a feeding box 200 is provided on one side of the weighing device 300, a feeding hopper 201 is provided on the top of the feeding box 200, and a discharge chute 202 is installed at one end of the feeding box 200. The discharge chute 202 is inclined and the bottom end of the discharge chute 202 is aligned with the upper center of the weighing pan 302.

[0051] As one possible embodiment, a movable plate 304 is provided below the weighing pan 302. A support column 305 is connected to the bottom center of the movable plate 304. The bottom end of the support column 305 contacts the top surface of the weighing device 300. Both ends of the bottom of the movable plate 304 are connected to a first spring 306. The first spring 306 is connected to an external power source through a power cord. A feeding plate 303 is provided at one end of the weighing device 300 near the sorting box 100. The bottom end of the feeding plate 303 faces the top of one end of the conveyor belt 111.

[0052] By setting an energized first spring 306, after the weighing pan 302 has finished weighing the battery steel shell, the first spring 306 on the right side of the movable plate 304 is energized, causing the first spring 306 to contract, thereby causing the movable plate 304 to tilt towards the sorting box 100, so that the weighed battery steel shell slides from the unloading plate 303 into the sorting box 100.

[0053] As one possible embodiment, the bottom of the sorting box 100 is connected to a support leg 103, and the end of the sorting box 100 away from the weighing device 300 is connected to a discharge plate 102. The sorting box 100 has a plurality of sorting ports 101, which are staggered and respectively opened on both sides of the sorting box 100.

[0054] In one possible embodiment, a support block 105 is connected to the middle of the sorting box 100. The upper end of the support block 105 contacts the upper inner wall of the conveyor belt 111. The support block 105 is used to support the upper part of the conveyor belt 111. Drive rollers 112 are provided at both ends of the conveyor belt 111. The two ends of the two drive rollers 112 are rotatably connected to the inner wall of the sorting box 100. The two drive rollers 112 rotate synchronously under the drive of the conveyor belt 111. One end of one of the drive rollers 112 is connected to a drive device.

[0055] In one possible embodiment, the first motor 109 is fixedly installed at the bottom of the sorting box 100. The top output end of the first motor 109 is connected to a drive shaft 108. The top end of the drive shaft 108 is fixedly connected to one end of the bottom of the baffle 104. The first motor 109 can drive the drive shaft 108 and the baffle 104 to rotate. By driving the drive shaft 108 to rotate, the drive shaft 108 can further drive the baffle 104 to rotate, so that the baffle 104 can block the battery steel shell and let the battery steel shell fall to the corresponding sorting port 101.

[0056] As one possible embodiment, the bottom of the baffle 104 is connected to a bristle 110, which can contact the top surface of the conveyor belt 111. A cleaning groove 106 is provided at the bottom of the inner wall of the sorting port 101. When the baffle 104 is folded to be parallel to the side wall of the sorting box 100, the bristle 110 is placed inside the cleaning groove 106.

[0057] As one possible embodiment, a through hole 107 is provided at the bottom of the cleaning tank 106, and a negative pressure pump is connected to the bottom end of the through hole 107. The negative pressure pump generates negative or positive pressure in the through hole 107 and the cleaning tank 106.

[0058] By setting bristles 110 at the bottom of the baffle 104, when the baffle 104 is rotated by the first motor 109, the bristles 110 can scrape the top surface of the conveyor belt 111 to remove dust from the conveyor belt 111, keeping the conveyor belt 111 clean and preventing the battery steel shell from being contaminated. Furthermore, by first blowing air into the cleaning tank 106 through a negative pressure pump, the dust on the surface of the bristles 110 is blown off into the cleaning tank 106. Then, the negative pressure pump creates negative pressure in the cleaning tank 106, adsorbing the dust in the cleaning tank 106 to the outside of the sorting box 100, thereby achieving the cleaning effect.

[0059] As one possible embodiment, the bottom of the sorting box 100 is provided with a through groove 113, and a scraper 114 is installed inside the through groove 113. The two ends of the scraper 114 are hinged to the inner wall of the through groove 113. A second spring 115 is connected between one end of the scraper 114 and the inner wall of the through groove 113. The second spring 115 always causes the top of the scraper 114 to press towards the conveyor belt 111.

[0060] The second spring 115 generates tension, causing the scraper 114 to always press towards the conveyor belt 111, thereby scraping away the dust on the outer wall of the conveyor belt 111 through the top of the scraper 114, further improving the cleaning power.

[0061] A PLC controller is installed inside the weighing device 300. The weighing pan 302, vision sensor 301 and first motor 109 are all connected to the PLC controller.

[0062] As one possible embodiment, the scraping mechanism further includes a sliding block 409, which is disposed on the bottom inner wall of the scraping plate 401. The outer wall of the sorting box 100 is provided with a sliding groove 408, and the sliding block 409 is slidably connected to the sliding groove 408. The sliding groove 408 has an inclined angle. One end of the scraping plate 401 is provided with an open groove 403. A cam 406 is disposed inside the open groove 403. The cam 406 is rotatably connected to the outer wall of the sorting box 100. A fixing plate 404 is also connected to the outer wall of the sorting box 100. A third spring 405 is connected between the fixing plate 404 and the inner wall of the open groove 403. A second motor 407 is fixedly installed on the outer end of the cam 406.

[0063] The second motor 407 drives the scraper 401 to move to one side. Because it has an inclined sliding groove 408, when the scraper 401 moves, it can exert a downward force in the direction of the conveyor belt 111, thereby making the scraper 402 contact the conveyor belt 111 more closely, thus improving the scraping effect. When the material passes through the scraper 402, the scraper 402 can also be cleaned.
