[0003] Existing lithium battery steel shell feeding devices generally use lifting-type distributing mechanisms or vibratory feeders to complete the single-row arrangement of lithium battery steel shells. Then, a conveyor transports the lithium battery steel shells to the corresponding positions. At this time, the spacing between the lithium battery steel shells on the conveyor may vary greatly, and some lithium battery steel shells may be arranged in the opposite direction, which is inconvenient for subsequent use of lithium battery steel shells.

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to an embodiment of the present utility model, a cylindrical lithium battery steel shell feeding device is provided, including: a conveyor 1, which includes a shell 11 and a conveyor belt 12, and the conveyor belt 12 is rotatably disposed in the top opening of the shell 11. A soft magnetic plate 2 is fixedly sleeved at the middle position of the outer periphery of the conveyor belt 12, and the outer periphery wall of the soft magnetic plate 2 is an arc-shaped surface that curves outward from the middle position to both sides.

[0032] Two baffles 3 are symmetrically fixed on the top side of the outer shell 11. A storage cylinder 4 is fixedly installed through the baffles 3, and a clamping plate 5 is provided in the opening of the storage cylinder 4.

[0033] The detection mechanism 6 is located on the outer periphery of the storage cylinder 4 and is used to monitor the position of the lithium battery steel shell on the conveyor belt 12.

[0034] The limiting mechanism 8 is located on the outer periphery of the corresponding clamping plate 5 and is used to constrain and limit the storage cylinder 4 and the corresponding clamping plate 5.

[0035] The drive mechanism 7 is located on the storage cylinder 4 and is used to drive the clamping plate 5 to slide or rotate inside the storage cylinder 4.

[0036] In this embodiment, when using the improved lithium battery steel casing feeding device, (please refer to...) Figure 1 and Figure 2 As shown, the conveyor belt 12 is equipped with two drive rollers, and the two ends of the drive rollers rotate through the shell wall of the outer casing 11. A drive structure is fixedly installed on the side wall of the outer casing 11 to cooperate with the drive rollers to drive the conveyor belt 12 to rotate. According to the existing feeding method of lithium battery steel shells, the lithium battery steel shells are arranged in a single row by a lifting distribution mechanism or a vibratory feeder, and then pushed onto the conveyor belt 12. Please refer to... Figure 1 and Figure 2As shown, as the transport machine 1 operates, due to the constraint and limitation of the lithium battery steel shell by the baffle 3, the lithium battery steel shell is placed on the arc surface of the soft magnetic plate 2. Thus, through the adsorption force between the soft magnetic plate 2 and the lithium battery steel shell, a corresponding frictional force is generated between the lithium battery steel shell and the transport belt 12.

[0037] Please refer to Figure 1 , Figure 3 and Figure 4 As shown, with the rotation of the conveyor belt 12, due to the friction between the lithium battery steel shells and the constraint of the baffle 3 on the lithium battery steel shells, the lithium battery steel shells move linearly towards the detection mechanism 6. The detection mechanism 6 completes the orientation detection of the lithium battery steel shells. When the end of the lithium battery steel shell moves to the middle position between the two clamping plates 5, if the orientation of the lithium battery steel shell is incorrect, the drive mechanism 7 is activated. Due to the constraint of the limiting mechanism 8 on the storage cylinder 4 and the clamping plate 5, the drive mechanism 7 first pushes the two clamping plates 5 to move towards each other, completing the clamping and limiting of the end of the lithium battery steel shell, so that the conveyor belt 12 will not move the lithium battery steel shell. Subsequently, due to the mutual contact between the lithium battery steel shell and the clamping plate 5, the clamping plate 5 can no longer slide out of the storage cylinder 4. At this time, the clamping plate 5 is subjected to a large axial pushing force, and the limiting mechanism 8 automatically releases the constraint between the storage cylinder 4 and the clamping plate 5. At this time, the drive mechanism 7 drives the lithium battery steel shell to rotate, and the lithium battery steel shell is flipped.

[0038] It should be noted that the transportation of the above-mentioned device is automatically controlled by an external control host;

[0039] In summary, when using this improved lithium battery steel shell feeding device, the clamping time of the lithium battery steel shells is controlled by the clamping plate 5, and the spacing between the lithium battery steel shells is adjusted so that the spacing between the lithium battery steel shells is equal after transportation. At the same time, the lithium battery steel shells are flipped in the opposite direction so that the lithium battery steel shells maintain the same orientation after transportation, which facilitates the use of the lithium battery steel shells after transportation.

[0040] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the top side of the conveyor belt 12 is coplanar with the top side of the outer shell 11, and the end of the baffle 3 near the discharge port of the conveyor 1 is provided with an L-shaped limiting strip and is slidably connected to the conveyor belt 12.

[0041] In this embodiment, please refer to Figure 1 As shown, when the lithium battery steel shell moves to the discharge port of the conveyor 1 as the conveyor belt 12 rotates, the lithium battery steel shell will not slip off the conveyor 1 due to the interception of the baffle 3. This is to prevent the conveyor belt 12 from continuing to rotate when it brings the lithium battery steel shell to the discharge port of the conveyor 1, causing the lithium battery steel shell to slip off the conveyor 1 and collide with the ground, thus damaging the lithium battery steel shell.

[0042] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the detection mechanism 6 includes a storage hole 61, which is opened on the baffle 3 and located on the outer periphery of the corresponding storage cylinder 4. A transparent plate 62 is fixedly installed in the opening at one end of the storage hole 61, and the opposite side of the transparent plate 62 is coplanar with the opposite side of the corresponding baffle 3. An infrared ranging sensor 63 is threadedly installed in the opening at the other end of the storage hole 61.

[0043] In this embodiment, please refer to Figure 1 and Figure 3 As shown, during the use of the device, the infrared ranging sensor 63 emits an inclined ranging laser beam that illuminates the baffle 3. As the conveyor belt 12 moves the lithium battery steel shell, when the ranging laser illuminates the lithium battery steel shell (the detection information of the infrared ranging laser is transmitted to the external control host via the Internet of Things), if the ranging laser illuminates the open end of the lithium battery steel shell, the illuminating position of the ranging laser on the lithium battery steel shell will move from the open end to the inside of the lithium battery steel shell as the lithium battery steel shell continues to move. The detection distance of the infrared ranging sensor 63 first decreases and then increases. If the ranging laser illuminates the other end of the lithium battery steel shell, the detection result continues to decrease. Based on the change in the ranging of the infrared ranging sensor 63, the orientation of the lithium battery steel shell is determined, and the lithium battery steel shell is adjusted to the corresponding orientation as needed.

[0044] The transparent plate 62 can block the opening of the storage hole 61 without affecting the use of the infrared ranging sensor 63, so as to prevent the moving lithium battery steel shell from colliding with the opening edge of the storage hole 61 and affecting the spacing between the lithium battery steel shells.

[0045] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the clamp 5 includes a disc 51 and a soft pad 52. The outer peripheral wall of the disc 51 is in contact with the inner wall of the corresponding storage cylinder 4. One side of the soft pad 52 is fixedly connected to one side of the disc 51, and the other side of the soft pad 52 is coplanar with the opposite side of the storage cylinder 4 and the opposite side of the baffle 3.

[0046] In this embodiment, please refer to Figure 1 , Figure 4 and Figure 6As shown, when the drive mechanism 7 drives the two clamping plates 5 to move towards each other, the disc 51 first pushes the soft pad 52 to abut against the lithium battery steel shell. As the soft pad 52 deforms, it forms a surface on the disc 51 that fits against the outer wall of the lithium battery steel shell. This allows a large frictional force to be generated between the disc 51 and the lithium battery steel shell, thus completing the clamping and limiting of the lithium battery steel shell. This overcomes the friction between the lithium battery steel shell and the conveyor belt 12, allowing the lithium battery steel shell to slide in the arc groove of the soft magnetic plate 2. The rotation of the conveyor belt 12 will not continue to follow the rotation of the conveyor belt 12.

[0047] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the drive mechanism 7 includes a motor 71, which is fixedly mounted on the side wall of the storage cylinder 4. The other side of the disc 51 is threaded with a threaded rod 72, and the drive end of the motor 71 is fixedly connected to the corresponding end of the threaded rod 72.

[0048] In this embodiment, please refer to Figure 4 As shown, after the drive mechanism 7 is started, the motor 71 drives the threaded shaft to rotate in the forward or reverse direction (the motor 71 can be a servo motor 71, etc.), thereby driving the disc 51 to slide out of or into the storage cylinder 4.

[0049] In a further preferred embodiment of this utility model, such as Figure 4 , Figure 5 and Figure 6 As shown, the limiting mechanism 8 includes several positioning grooves 81, which are equally spaced on the outer peripheral wall of the corresponding disc 51. Several storage grooves 82 are symmetrically opened on the inner wall of the storage cylinder 4 at the positions corresponding to the positioning grooves 81. A piston push rod 83 is slidably installed in the storage groove 82. A ball bearing 84 is rotatably installed in the piston push rod 83, and one end of the ball bearing 84 near the corresponding positioning groove 81 is inserted into the corresponding positioning groove 81.

[0050] In this embodiment, please refer to Figure 4 and Figure 5 As shown, when the threaded rod 72 rotates in the forward or reverse direction, as the threaded rod 72 rotates, due to the mutual contact between the ball 84 and the inner wall of the positioning groove 81, the disc 51 will not rotate with the threaded rod 72, thereby causing the rotating threaded rod 72 to drive the disc 51 to slide out of or into the storage cylinder 4.

[0051] After the lithium battery steel shell is clamped and limited, the disc 51 cannot continue to slide out of the storage cylinder 4 due to the mutual contact between the disc 51, the soft pad 52 and the lithium battery steel shell. At this time, the threaded rod 72 is jammed with the disc 51. The motor 71 applies an axial driving force to the lithium battery steel shell through the threaded rod 72, the disc 51 and the soft pad 52 to drive the lithium battery steel shell to flip. The device has a high degree of automation.

[0052] In a further preferred embodiment of this utility model, such as Figure 4 , Figure 5 and Figure 6 As shown, the storage groove 82 is filled with air, the positioning groove 81 has a cross-sectional shape of a quarter circle, and the length of the positioning groove 81 is greater than the diameter of the ball 84 and less than the thickness of the disk 51.

[0053] In this embodiment, please refer to Figure 4 , Figure 5 and Figure 6 As shown, during the process of the disc 51 sliding inside the storage cylinder 4, (the outer peripheral wall of the ball 84 is in contact with the inner wall of the corresponding positioning groove 81), the ball 84 rolls inside the positioning groove 81. At this time, due to the mutual contact between the outer wall of the ball 84 and the inner wall of the positioning groove 81, the disc 51 slides along a linear trajectory.

[0054] Working principle: When using this improved lithium battery steel shell feeding device, the existing lithium battery steel shell feeding method is adopted. The lithium battery steel shells are arranged in a single row through a lifting distribution mechanism or a vibrating plate, and then pushed onto the soft magnetic plate 2. The rotating conveyor belt 12 then moves the lithium battery steel shells to the corresponding positions. During this process, the infrared ranging sensor 63 detects whether the end of the lithium battery steel shell has moved to the middle between the two clamping plates 5. Then, the clamping plates 5 clamp and limit the lithium battery steel shells, adjust the distance between two adjacent lithium battery steel shells, and drive the reverse lithium battery steel shells to flip through the rotation of the clamping plates 5, so that several lithium battery steel shells are transported in the same direction to the discharge end of the conveyor 1.

[0055] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0056] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
