[0021] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0022] like Figure 1-3As shown, a battery detection and sorting device comprises a battery loading box 1, a battery conveying channel 11 extending outward is provided on the side wall of the battery loading box 1, and a battery detector 12 for detecting battery performance and grade is provided on the upper and lower sides of the outer end of the battery conveying channel 11, and also comprises a fixing plate 2, a sorting barrel 21 is provided on the top surface of the fixing plate 2, a circular sorting cavity 22 is formed inside the sorting barrel 21, a cylindrical sorting block 3 is provided in the circular sorting cavity 22, which is coaxially arranged with the circular sorting cavity 22 and can rotate around the axis relative to the sorting barrel 21, and the cylindrical sorting block 3 is provided in the circular sorting cavity 22. The side wall of the block 3 is provided with a plurality of positioning cavities 31 for positioning the battery and arranged at equal intervals. After the battery is placed in the positioning cavity 31, the inner wall of the circular sorting cavity 22 keeps in contact with the side wall of the battery. The side wall of the circular sorting cavity 22 is provided with a feed port 221 corresponding to the position of one of the positioning cavities 31 and connected to the outer end of the battery conveying channel 11. The bottom of the sorting barrel 21 is provided with a feed channel 211 for the battery to pass through corresponding to the bottom of each positioning cavity 31. The bottom of each positioning cavity 31 is provided with an opening. The bottom opening of each positioning cavity 31 is provided with a A reciprocating baffle 32 is provided, and the battery tester 12 is arranged at the outer opening of the feed port 221. The horizontal height of the bottom edge of the positioning cavity 31 is consistent with the bottom surface height of the feed port 221, and the width of the feed port 221 is consistent with the diameter of the battery; the above-mentioned battery loading box is consistent with the existing device and equipment, and can transport batches of batteries to the designated channel in an orderly manner. The above-mentioned battery tester is a product currently available on the market and is a prior art, which will not be repeated here. The above-mentioned battery loading box stores a large number of produced batteries, and the batteries are transported from the battery loading box to the battery conveying channel. The batteries are moved one by one in the battery conveying channel to the location of the battery tester. After being detected by the battery tester, they are directly transported to the positioning cavity of the columnar sorting block through the feed port, and the batteries in the positioning cavity are transported away from different unloading channels by the rotating columnar sorting block, so as to realize batch detection and fast and efficient sorting of batteries, and can detect and sort batteries of various performance levels, effectively improving the detection and sorting efficiency of batteries, and then improving the production efficiency of batteries.

[0023] The above-mentioned baffle blocks the opening at the bottom of each positioning cavity at the bottom of each positioning cavity to form support for the battery. When the battery is rotated to the top of the corresponding unloading channel through the columnar sorting block, the baffle can move automatically to cancel the blockage of the bottom of the positioning cavity, so that the battery automatically falls into the corresponding unloading channel, thereby realizing rapid sorting of different batteries. Batteries of different performance levels correspond to different unloading channels. As the columnar sorting block rotates, when the battery rotates to the top of the corresponding unloading channel, the baffle will automatically move, allowing the battery to leave the positioning cavity and enter the unloading channel. After the battery leaves, the baffle automatically returns to its position to block the opening at the bottom of the positioning cavity.

[0024] like Figure 2 and 3As shown, a plurality of fixed blocks 33 corresponding to each baffle 32 are provided on the bottom surface of the columnar sorting block 3, an electromagnet 331 is provided on the fixed block 33 on the side facing the baffle 32, a magnetic attraction member 321 corresponding to the electromagnet 331 is provided on the side wall of the baffle 32, at least one guide groove 332 is provided on the side wall of the fixed block 33, a guide rod 322 extending into the guide groove 332 is provided on the side wall of the baffle 32, a return spring 333 connected to the guide rod 322 is provided in the guide groove 332, a driving shaft 34 extending downward and passing through the bottom of the sorting barrel 21 is provided at the axis of the columnar sorting block 3, and the bottom end of the driving shaft 34 is connected to a servo motor 330 for driving the columnar sorting block 3 to rotate intermittently. 5 is connected to the output shaft; the above-mentioned electromagnet and servo motor are both existing technologies and will not be described in detail here. The above-mentioned magnetic suction member is made of materials such as iron, cobalt, and nickel that can be attracted by the electromagnet. The above-mentioned fixed block is fixed to the bottom of the columnar sorting block. The servo motor controls the driving shaft to drive the columnar sorting block to rotate intermittently. Each time the positioning cavity of the columnar sorting block rotates to the top of the unloading channel, it pauses for a specified time. During this time period, the battery can leave the positioning cavity and enter the specified unloading channel. The detected battery can enter the positioning cavity. Subsequently, the columnar sorting block is started again. When the batteries in some positioning cavities rotate to the top of the corresponding unloading channel, the baffle leaves the positioning cavity, so that the battery automatically enters the corresponding unloading channel.

[0025] The baffle is slidably connected to the guide groove of the fixed block through two guide rods on the side wall. The fixed block can control the movement of the baffle toward the fixed block by adsorbing the magnetic suction part when the electromagnet is energized. At this time, the reset spring contracts and the baffle leaves the bottom opening of the positioning cavity, so that the battery can be transported from the unloading channel. When the battery leaves the positioning cavity, the electromagnet is powered off, and the baffle automatically returns to its position under the action of the reset spring, and returns to the bottom opening of the positioning cavity to form a blockage, so that the baffle can move automatically, and the opening and closing of the bottom opening of the positioning cavity are controlled by signals of different performance levels to control the battery to accurately enter the corresponding unloading channel, thereby achieving more precise sorting control.

[0026] like Figure 1 , 4As shown in , 5, a plurality of battery collecting channels 41 corresponding to each unloading channel 211 are provided at the lower outer side of the fixed plate 2, the battery collecting channel 41 is communicated with the bottom opening of the unloading channel 211, and a support column 23 connected to the bottom surface of the fixed plate 2 is provided at the top of each battery collecting channel 41, the battery collecting channel 41 is located at the adjacent side of the unloading channel 211, and a support portion 411 extending downward toward the unloading channel 211 is provided at the bottom of the battery collecting channel 41, a battery receiving cavity 412 is provided in the battery collecting channel 41, and a U-shaped pushing plate 42 for pushing the battery into the battery receiving cavity 412 is provided above the supporting portion 411, the U-shaped pushing plate 42 includes an arc-shaped matching portion 421 that matches with the vertical battery and two sliding portions 422 that are slidably fitted into the battery receiving cavity 412 and respectively abut against the two side walls of the battery receiving cavity 412, the arc-shaped matching portion 421 matches with the unloading channel 211 and The top opening edge of the arc-shaped matching portion 421 is flush with the bottom opening edge of the discharge channel 211, and a baffle 423 that can close the bottom opening of the discharge channel 211 is provided at the outer edge of the top opening of the arc-shaped matching portion 421. A limiting protrusion 424 is provided at the bottom of the arc-shaped matching portion 421, and a limiting slide groove 413 that cooperates with the limiting protrusion 424 is provided on the top surface of the support portion 411. A telescopic spring 414 connected to the limiting protrusion 424 is provided in the limiting slide groove 413. A plurality of control blocks 36 corresponding to each arc-shaped matching portion 421 are provided on the side wall of the driving shaft 34, and a first magnetic member 361 is provided at the end of the control block 36. A matching block 425 corresponding to the control block 36 is provided on the outer wall of the arc-shaped matching portion 421, and a second magnetic member 426 that magnetically repels the first magnetic member 361 is provided at the end of the matching block 425, and the end of the matching block 425 can abut against the end of the control block 36.

[0027] The battery collection channel is located below the fixed plate, and the fixed plate and the sorting barrel are supported and fixed by support columns. The columnar sorting block rotates coaxially relative to the sorting barrel. The battery collection channel can collect and store the different sorted batteries separately for subsequent transportation. The first magnetic part and the second magnetic part can be made of strong magnetic materials such as neodymium iron boron to achieve mutually repelling properties.

[0028] The above-mentioned battery directly enters the arc-shaped matching part of the U-shaped pushing plate from the feeding channel. The arc-shaped matching part can push the battery, push the battery away from the bottom of the feeding channel and enter the battery storage cavity, so that the battery can continue to fall from the feeding channel, avoid clogging of the feeding channel, and realize continuous sorting and transportation of the battery. The sliding part abuts against the two sides of the battery storage cavity, plays a supporting and limiting role for the arc-shaped matching part, assists the movement of the arc-shaped matching part, avoids maintaining the stability of the arc-shaped matching part, avoids offset, and pushes the battery away from the feeding channel. The baffle on the outside of the arc-shaped matching part closes the bottom opening of the feeding channel to prevent the remaining batteries in the feeding channel from falling out to the outside and affecting the rapid collection of the batteries, and easily damaging the batteries.

[0029] The matching blocks on the outer side of the arc-shaped matching part correspond to the control blocks on the side walls of the driving shaft respectively. When the servo motor controls the driving shaft to drive the columnar sorting block to rotate, the first magnetic part at the end of the control block gradually approaches the second magnetic part at the end of the matching block. In the process that the first magnetic part gradually approaches the second magnetic part until it is closest to the second magnetic part, the U-shaped pushing plate is pushed by the repulsive force, so that the U-shaped pushing plate drives the battery to automatically enter the battery storage cavity, and the baffle plate synchronously closes the bottom opening of the unloading channel, so that the U-shaped pushing plate can be synchronously driven to move to push the battery during the rotation of the driving shaft, which saves energy consumption, makes the driving faster and more efficient, and improves the battery sorting efficiency. The limiting protrusion at the bottom of the above-mentioned arc-shaped matching part is located at the limit In the slide groove, the telescopic spring in the limit slide groove is in a contracted state at this time. When the driving shaft rotates again, the control block and the second magnetic part leave the matching block and the first magnetic part, canceling the repulsion of the first magnetic part, and the U-shaped push plate can automatically return to its position through the action of the telescopic spring and connect with the unloading channel again. During the battery detection and sorting process, the U-shaped push plate can automatically move and push the material synchronously with the rotation of the driving shaft through the action of the first magnetic part, the second magnetic part and the telescopic spring, and transfer the battery to facilitate the rapid transfer of the battery in the unloading channel, and avoid the accumulation of batteries in the unloading channel to affect the continuous detection and sorting of the batteries. At the same time, there is no need to occupy additional drive control and energy consumption, effectively realizing energy saving and cost reduction.

[0030] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
