Description

Technical Field

[0001] The present invention belongs to the technical field of lithium battery processing, and specifically relates to a processing device for the housing of a lithium-ion battery. Background Art

[0002] The processing device for the housing of a lithium-ion battery is a series of equipment and systems used to manufacture the outer shell of a lithium battery, covering multiple processes such as material cutting, stamping, and surface treatment. These devices ensure that each outer shell meets strict dimensional and quality standards through an efficient automated production line. Among them, deburring is an important step in the processing, because it can not only improve the appearance quality of the outer shell, but also eliminate potential safety hazards and prevent burrs from damaging the internal components of the battery during subsequent assembly. Through deburring, the smoothness and cleanliness of the lithium battery outer shell can be ensured, thereby improving the overall reliability and service life of the battery.

[0003] When the existing processing device for the housing of a lithium-ion battery processes the outer shell of a lithium-ion battery, especially when performing deburring operations, the following deficiencies still exist:

[0004] 1. When the existing deburring equipment for the housing of a lithium-ion battery deburrs the outer shell of a lithium battery, it mainly holds the battery housing with burrs by hand and grinds it with a grinding wheel. When grinding, in order to better and faster remove the burrs on one side of the battery housing, the staff needs to press the other side of the battery housing. During the operation, the staff's hand is extremely easy to be cut, seriously affecting the personal safety of the on-site staff.

[0005] 2. When the existing deburring equipment for the housing of a lithium-ion battery deburrs the outer shell of a lithium battery, it can only deburr one side of a single lithium battery outer shell at a time. Whether it is processing a tubular lithium battery outer shell or an open-type lithium battery outer shell, it seriously affects the processing progress of the battery outer shell, and the processing efficiency of the lithium battery outer shell is severely affected.

[0006] 3. When some of the existing deburring equipment for the housing of a lithium-ion battery deburrs the outer shell of a lithium battery, it can position and clamp the lithium battery outer shell through a clamping device. However, when facing lithium battery outer shells of different sizes, it cannot ensure clamping stability. When the lithium battery outer shell is being ground, once the edge of the lithium battery outer shell is not parallel to the grinding sandpaper or grinding disc, some burrs on the lithium battery outer shell will not be removed, while the edge part of the lithium battery outer shell is over-ground, resulting in the lithium battery not meeting the dimensional requirements or the lithium battery outer shell being deformed. Summary of the Invention

[0007] To overcome the above deficiencies, the present invention provides a processing device for a lithium-ion battery housing, which solves the problems in the prior art.

[0008] To achieve the above object, the present invention provides the following technical solution: A processing device for a lithium-ion battery housing, comprising:

[0009] A base plate, on which two pairs of support plates are fixedly connected. A rotating shaft is rotatably connected between each pair of support plates. On one of the support plates in each pair of support plates, a driving motor is fixedly connected. The output end of the driving motor penetrates through the corresponding side support plate and is fixedly connected to the rotating shaft coaxially. Two synchronous belt pulleys are fixedly connected to the rotating shaft coaxially, and a synchronous belt is sleeved on the four synchronous belt pulleys;

[0010] The synchronous belt is fixedly connected with connection ports at equal intervals. A battery housing positioning and clamping mechanism is arranged on the connection ports, and a two-way grinding mechanism is arranged on the base plate.

Two limiting strips are fixedly connected to the rotating seat. The nuts are slidably connected between the two limiting strips. An installation plate is fixedly connected to the nut. Grinding motors are arranged at one end of the two installation plates away from each other. Grinding wheels are rotatably connected to one end of the two installation plates close to each other. The output end of the grinding motor penetrates through the installation plate and is fixedly connected to the grinding wheel coaxially.

[0012] As a further solution of the present invention: A servo motor is fixedly connected to the base plate. The output end of the servo motor penetrates through the rotating seat and is fixedly connected to the two-way threaded rod coaxially.

[0013] As a further solution of the present invention: The positioning and clamping mechanism includes a longitudinal clamping box fixedly connected to the connection port. Two telescopic rods are fixedly connected in the longitudinal clamping box. A return spring is sleeved outside the telescopic rods. The output ends of the two telescopic rods are fixedly connected to a movable plate. Corresponding to the positions of the two telescopic rods on the longitudinal clamping box, a sliding groove is opened. The two ends of the return spring are respectively abutted against the inner wall of the longitudinal clamping box and the movable plate.

[0014] As a further solution of the present invention: A fixing plate is fixedly connected to the longitudinal clamping box, and a transverse clamping box is fixedly connected to the fixing plate.

[0015] As a further solution of the present invention: A gear is rotatably connected in the transverse clamping box. Two tooth plates are slidably connected to the inner walls on both sides of the transverse clamping box. Both tooth plates are engaged with the gear.

[0016] As a further solution of the present invention: positioning rods are rotatably connected to the ends of the two toothed plates away from each other, a stepping motor is fixedly connected to the transverse clamping box, and the output end of the stepping motor penetrates through the transverse clamping box and is coaxially fixedly connected to a gear.

[0017] As a further solution of the present invention: two brackets are fixedly connected to the base plate, and a mating plate is fixedly connected to the brackets.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. By providing a longitudinal clamping box at the connection port on the synchronous belt, the present invention can clamp the lithium battery shell, so that when deburring the burrs on the lithium battery shell, on-site workers can be prevented from directly contacting the burrs on the lithium battery shell, thus avoiding hand injuries to the workers and improving the safety factor of production personnel in the deburring process.

[0020] 2. By providing a synchronous belt and a two-way grinding mechanism, the present invention can perform in-line deburring treatment on multiple lithium battery shells at the same time. Furthermore, by providing two grinding wheels that can be adjusted in opposite directions, the two sides of a single lithium battery shell can be deburred simultaneously, which further improves the deburring work efficiency.

[0021] 3. By providing a positioning and clamping mechanism, the movable plate in the longitudinal clamping box, under the action of the telescopic rod and the return spring, can cooperate with the fixed plate to clamp lithium batteries of different widths. The two equally spaced moving toothed plates in the transverse clamping box can longitudinally clamp and center the lithium battery shell through the positioning rod, so that when grinding the two ends of the lithium battery shell, it can be avoided that the lithium battery shell is skewed, resulting in incomplete deburring and excessive grinding.

Specific implementation mode

[0029] The technical solution of this patent will be further described in detail below in conjunction with the specific implementation mode.

[0030] As Figures 1-6 shown, the present invention provides a technical solution:

[0031] Base plate 1, two pairs of support plates 2 are fixedly connected to the base plate 1, a rotating shaft 26 is rotatably connected between each pair of support plates 2, a drive motor 3 is fixedly connected to one of the support plates 2 in each pair of support plates 2, the output end of the drive motor 3 penetrates through the corresponding support plate 2 on one side and is coaxially fixedly connected to the rotating shaft 26, two synchronous belt pulleys 4 are coaxially fixedly connected to the rotating shaft 26, and a synchronous belt 5 is sleeved on the four synchronous belt pulleys 4. The drive motor 3 can drive the rotating shaft 26 between the two support plates 2 to rotate, so that the synchronous belt pulleys 4 rotate, and thus the synchronous belt 5 can operate normally;

[0032] The connection ports 27 are fixedly connected to the synchronous belt 5 at equal intervals, a battery case positioning and clamping mechanism is arranged on the connection ports 27, and a two-way grinding mechanism is arranged on the base plate 1;

[0033] The two-way grinding mechanism includes a rotating seat 6 fixedly connected to the base plate 1. A two-way threaded rod 7 is rotatably connected inside the rotating seat 6. Both ends of the two-way threaded rod 7 are threadedly connected with nuts 8. Two limiting strips 9 are fixedly connected to the rotating seat 6. The nuts 8 are slidably connected between the two limiting strips 9. An installation plate 10 is fixedly connected to the nut 8. Grinding motors 11 are arranged at one end of the two installation plates 10 away from each other. Grinding wheels 12 are rotatably connected to one end of the two installation plates 10 close to each other. The output end of the grinding motor 11 penetrates through the installation plate 10 and is coaxially and fixedly connected to the grinding wheel 12. A servo motor 13 is fixedly connected to the base plate 1. The output end of the servo motor 13 penetrates through the rotating seat 6 and is coaxially and fixedly connected to the two-way threaded rod 7. In order to adapt to the grinding work of lithium battery casings of different lengths, it is necessary to adjust the distance between the two grinding wheels 12 for adaptation. When adjusting the grinding wheel 12, the two-way threaded rod 7 can be restricted by controlling the servo motor 13. When the two-way threaded rod 7 rotates, the two nuts 8 will move relatively closer or farther away. The limiting strips 9 can ensure the stability of the movement of the nuts 8. Then the positions of the installation plates 10 and the grinding wheels 12 on the nuts 8 can be adjusted synchronously. The grinding motor 11 can provide power for the rotation of the grinding wheel 12;

[0034] The positioning and clamping mechanism includes a longitudinal clamping box 14 fixedly connected to the connection port 27. Two telescopic rods 15 are fixedly connected inside the longitudinal clamping box 14. A return spring 16 is sleeved outside the telescopic rods 15. The output ends of the two telescopic rods 15 are fixedly connected with a movable plate 17. Corresponding to the positions of the two telescopic rods 15 on the longitudinal clamping box 14, a sliding groove 28 is opened. The two ends of the return spring 16 are respectively abutted against the inner wall of the longitudinal clamping box 14 and the movable plate 17. A fixed plate 18 is fixedly connected to the longitudinal clamping box 14. A transverse clamping box 19 is fixedly connected to the fixed plate 18. A gear 20 is rotatably connected inside the transverse clamping box 19. Two toothed plates 21 are slidably connected to the inner walls on both sides of the transverse clamping box 19. Both toothed plates 21 are meshed with the gear 20. One end of each of the two toothed plates 21 away from each other is rotatably connected with a positioning rod 22. A stepping motor 23 is fixedly connected to the transverse clamping box 19. The output end of the stepping motor 23 penetrates through the transverse clamping box 19 and is coaxially fixedly connected with the gear 20. Two brackets 24 are fixedly connected to the base plate 1. A matching plate 25 is fixedly connected to the brackets 24. The purpose of setting the positioning and clamping mechanism is as follows: By setting the positioning and clamping mechanism, the movable plate 17 in the longitudinal clamping box 14, under the action of the telescopic rods 15 and the return spring 16, can cooperate with the fixed plate 18 to clamp lithium batteries of different widths. The two equidistantly moving toothed plates 21 in the transverse clamping box 19 can longitudinally clamp and center the lithium battery shell through the positioning rods 22. In this way, when grinding the two ends of the lithium battery shell, it can be avoided that the incomplete deburring and excessive grinding are caused by the skew of the lithium battery shell. When the longitudinal clamping box 14 is specifically operating, the stepping motor 23 can be controlled to drive the gear 20. When the gear 20 rotates, the two toothed plates 21 meshed with it can move relatively equidistantly, and the positioning rods 22 can further clamp and center the positioned lithium battery shell by the movable plate 17 and the fixed plate 18. It should be noted that during grinding, due to the setting of the matching plate 25, when the transverse clamping box 19 on the surface of the high position of the synchronous belt 5 is about to approach the grinding wheel 12, after the two positioning rods 22 contact the matching plate 25, they will rotate 90 degrees and disengage from the clamping and positioning of the lithium battery shell. At this time, the stepping motor 23 controls the gear 20 to rotate, so that the toothed plates 21 and the positioning rods 22 contract to avoid contacting the grinding wheel.

[0035] The working principle of the present invention is as follows:

[0036] Four synchronous belt wheels 4 are sleeved with a synchronous belt 5. The driving motor 3 can drive the rotation of the rotating shaft 26 between the two support plates 2, so that the synchronous belt wheels 4 rotate, and thus the synchronous belt 5 can operate normally. By setting the longitudinal clamping box 14 on the connection port 27 on the synchronous belt 5;

[0037] In order to adapt to the grinding work of lithium battery casings of different lengths, it is necessary to adjust the distance between the two grinding wheels 12 for adaptation. When adjusting the grinding wheels 12, the bidirectional threaded rod 7 can be restricted by controlling the servo motor 13. When the bidirectional threaded rod 7 rotates, the two nuts 8 will move relatively closer or farther away. The limiting strip 9 can ensure the stability of the movement of the nuts 8. Then, the positions of the mounting plate 10 on the nuts 8 and the grinding wheels 12 can be adjusted synchronously. The grinding motor 11 can provide power for the rotation of the grinding wheels 12. By setting the synchronous belt 4 and the bidirectional grinding mechanism, burr removal treatment can be carried out on multiple lithium battery casings in a production line manner. Furthermore, by setting two oppositely adjustable grinding wheels 12, burr removal treatment can be carried out on both sides of a single lithium battery casing simultaneously, which further improves the burr removal work efficiency;

[0038] The purpose of setting the positioning and clamping mechanism is as follows: By setting the positioning and clamping mechanism, the movable plate 17 in the longitudinal clamping box 14, under the action of the telescopic rod 15 and the return spring 16, can cooperate with the fixed plate 18 to clamp lithium batteries of different widths. The two equidistantly moving toothed plates 21 in the transverse clamping box 19 can longitudinally clamp and center the lithium battery casing through the positioning rod 22. In this way, when grinding the two ends of the lithium battery casing, it can be avoided that the burr removal is incomplete and the grinding is excessive due to the skew of the lithium battery casing. When the longitudinal clamping box 14 is specifically operating, the stepping motor 23 can be controlled to drive the gear 20. When the gear 20 rotates, the two toothed plates 21 meshing with it can move relatively equidistantly, and the positioning rod 22 can further clamp and center the position of the lithium battery casing that has been positioned by the movable plate 17 and the fixed plate 18. It should be noted that during grinding, due to the setting of the matching plate 25, when the transverse clamping box 19 on the high surface of the synchronous belt 5 is about to approach the grinding wheel 12, after the two positioning rods 22 contact the matching plate 25, they will rotate 90 degrees and disengage from the clamping and positioning of the lithium battery casing. At this time, the stepping motor 23 controls the rotation of the gear 20, so that the toothed plates 21 and the positioning rods 22 contract to avoid contacting the grinding wheel.

[0039] The above has made a detailed description of the preferred embodiments of this patent. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can also be made without departing from the purpose of this patent.
