Description

Technical Field

[0001] The invention relates to the field of battery cover plate processing equipment, in particular to a precisely positioned pole welding rotating disk. Background Art

[0002] The battery cover is welded or riveted to the shell to fix and seal the inside of the battery to prevent chemical leakage. The poles on the cover are welded to the battery cell tabs to ensure the conduction of the battery cell's charging and discharging currents. A variety of protection mechanisms are also used to prevent safety hazards such as battery overheating and short circuits. The pole welding of the battery cover is a key process in the cover production.

[0003] The welding process of the battery cover and the pole is divided into the following steps. First, the cover and the pole are transferred to the carrier through the grabbing mechanism, and then the pole and the cover are welded by laser welding. In order to improve the welding efficiency of the battery cover pole, the carrier is often placed on a rotating carrier plate. Multiple carriers can be set on the rotating carrier plate. Each carrier can be used as a separate welding unit. When in use, just control the rotation of the rotating carrier plate to transport the carrier and the cover pole to the welding position.

[0004] The rotation of the rotating carrier plate is often controlled by a motor, which is located at the bottom of the rotating carrier plate. When the rotating carrier plate needs to be rotated, the motor is started to drive the rotating carrier plate to rotate. However, the positioning accuracy of the motor may deteriorate after working for a long time, and directly controlling the rotation of the rotating carrier plate may result in inaccurate positioning due to the error of the motor itself, which may cause the rotating carrier plate to fail to accurately transport the cover plate pole to the welding position. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a precisely positioned pole welding rotating disk to solve the technical problem that the general rotating carrier disk is controlled by a motor to rotate, but when inaccurate positioning occurs, the rotating carrier disk may not be able to accurately transport the cover plate pole to the welding position.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a precisely positioned pole welding rotating disk, comprising a motor, a mounting seat and a rotating carrier disk, the output end of the motor is connected to a rotating column, the outer wall of the rotating column is fixedly provided with a fixing seat, the outer wall of the rotating column is fixedly provided with a first residual gear, a third residual gear, a fourth residual gear and a fifth residual gear, a coaxial reversing mechanism is installed inside the mounting seat, the outer wall of the coaxial reversing mechanism is meshed with a gear ring, the outer wall of the gear ring is meshed with a first composite gear, the first composite gear is meshed with a second composite gear, an insert block is movably provided inside the mounting seat, and the insert block is controlled to move by the second composite gear, a press-type self-locking mechanism is provided between the insert block and the mounting seat, and the top of the rotating column is connected to the rotating carrier disk through a speed regulating mechanism.

[0007] The present invention is further configured such that the coaxial reversing mechanism includes an upper gear, a lower gear, a rotating shaft, a first bevel gear and a second bevel gear, the upper gear and the lower gear are fixedly arranged at the top and the bottom of the rotating shaft, a group of second bevel gears are fixedly arranged on the opposite surfaces of the upper gear and the lower gear, and a group of the second bevel gears are all meshed with the first bevel gear.

[0008] The present invention is further configured such that the first compound gear and the second compound gear are composed of a combination of a spur gear and a bevel gear, the first compound gear is meshed with the gear ring through the spur gear, and the first compound gear and the second compound gear are meshed with each other through the bevel gear.

[0009] The present invention is further configured such that a groove is provided at the bottom of the plug block, a plurality of fixed teeth are provided inside the groove, and the spur gear of the second composite gear controls the movement of the plug block through the meshing of the fixed teeth.

[0010] The present invention is further configured as follows: the speed regulating mechanism includes a second residual gear, a gear column, a first speed regulating gear, a second speed regulating gear and an inner gear ring, the second residual gear is fixedly arranged on the outer wall of the rotating column, the gear column is rotatably arranged on the top of the fixed seat, and the second residual gear and the gear column are meshed with each other, the outer wall of the gear column is fixedly provided with the first speed regulating gear, the first speed regulating gear is meshed with the second speed regulating gear, the second speed regulating gear and the inner gear ring are meshed with each other, and the top of the inner gear ring is connected to the rotating carrier disk.

[0014] To sum up, the present invention mainly has the following beneficial effects: the present invention first contacts and meshes with the coaxial reversing mechanism through the first residual gear, pulls the plug block out of the fixed seat, and locks the plug block inside the mounting seat by pressing the self-locking button, and then the rotating carrier disk can rotate under the action of the motor until the third residual gear contacts and meshes with the coaxial reversing mechanism, and after the meshing is completed, the self-locking button is unlocked and pressed, at which time the plug block pops out, and the fourth residual gear causes the plug block to slowly rotate out until it enters the fixed seat.

DETAILED DESCRIPTION

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] A precisely positioned pole welding rotating disc, such as Figure 1-7 As shown, it includes a motor 1, a mounting seat 2 and a rotating carrier plate 3. The mounting seat 2 is fixedly arranged on the top of the motor 1, and the rotating carrier plate 3 is rotatably arranged above the mounting seat 2. A carrier used for welding the cover plate pole is placed on the top of the rotating carrier plate 3. The rotating carrier plate 3 can be rotated to turn the carrier to the welding position.

[0025] The output end of the motor 1 is connected to a rotating column 22, the top of the rotating column 22 is connected to a rotating carrier plate 3 through a speed regulating mechanism, a fixing seat 24 is fixedly arranged on the outer wall of the rotating column 22, and a first residual gear 4, a second residual gear 16, a third residual gear 20, a fourth residual gear 21 and a fifth residual gear 25 are fixedly arranged on the outer wall of the rotating column 22. When it is necessary to control the rotation of the rotating carrier plate 3, the motor 1 is started, and the output end of the motor 1 drives the rotating column 22 to rotate synchronously until the first residual gear 4 contacts the coaxial reversing mechanism, and the coaxial reversing mechanism rotates. The outer wall of the coaxial reversing mechanism is meshed with a gear ring 10, and the gear ring 1 The outer wall of the mounting seat 2 is meshed with a first composite gear 11, and the first composite gear 11 is meshed with a second composite gear 12. An insert block 13 is movably provided inside the mounting seat 2, and the insert block 13 is controlled to move by the second composite gear 12. A press self-locking mechanism 14 is provided between the insert block 13 and the mounting seat 2. When the coaxial reversing mechanism rotates, the gear ring 10 rotates synchronously, and the first composite gear 11 meshed with the gear ring 10 rotates accordingly, thereby driving the second composite gear 12 to rotate synchronously. When the second composite gear 12 rotates, the insert block 13 matched with the second composite gear 12 moves outward to release the positioning of the fixing seat 24.

[0026] In the above structure, the first compound gear 11 and the second compound gear 12 are composed of a spur gear and a bevel gear. The first compound gear 11 is meshed with the gear ring 10 through the spur gear, and the first compound gear 11 and the second compound gear 12 are meshed with each other through the bevel gear. That is, when the gear ring 10 rotates, the first compound gear 11 will rotate with it under the action of the spur gear, and the second compound gear 12 will rotate synchronously with the first compound gear 11 through the bevel gears meshing with each other. A groove is provided at the bottom of the plug block 13, and a plurality of fixed teeth are arranged inside the groove. The spur gear of the second compound gear 12 controls the movement of the plug block 13 through the meshing of the fixed teeth, so when the first compound gear 11 rotates, the first compound gear 11 rotates synchronously with the second compound gear 12 through the meshing of the bevel gears. When the second composite gear 12 rotates, the flat gear part of the second composite gear 12 will come into contact and mesh with the fixed teeth, thereby pushing the plug block 13 to one side, so that the plug block 13 is separated from the fixed seat 24. A press-to-lock mechanism 14 is provided between the plug block 13 and the mounting seat 2. When the plug block 13 leaves the fixed seat 24 and the first residual gear 4 completes the meshing, the plug block 13 will be inserted into the interior of the mounting seat 2 and fixed by the press-to-lock mechanism 14. The press-to-lock mechanism 14 is a common self-locking mechanism, such as a press-type ballpoint pen, which is fixed by pressing once and unlocked by pressing again. Therefore, it is not described in detail, and those skilled in the art can select a suitable structure for use.

[0027] When the rotating column 22 rotates, the first residual gear 4 first contacts and meshes with the coaxial reversing mechanism, and then the plug block 13 disengages from the fixed seat 24, the first residual gear 4 disengages from the meshing with the coaxial reversing mechanism, and the second residual gear 16 starts to work. The second residual gear 16 belongs to the speed regulating mechanism, and the speed regulating mechanism also includes a gear column 17, a first speed regulating gear 18, a second speed regulating gear 19 and an inner gear ring 23. The second residual gear 16 is fixedly arranged on the outer wall of the rotating column 22, and the gear column 17 is rotatably arranged on the top of the fixed seat 24, and the second residual gear 16 and the gear column 17 are meshed with each other. The outer wall of the gear column 17 is fixedly provided with The first speed regulating gear 18 is meshed with the second speed regulating gear 19, the second speed regulating gear 19 is meshed with the inner gear ring 23, and the top of the inner gear ring 23 is connected to the rotating carrier disc 3, the second residual gear 16 and the fifth residual gear 25 are meshed with the gear column 17 on the same horizontal plane, and the second residual gear 16 is in contact and meshed with the gear column 17 under the rotation of the rotating column 22, thereby driving the first speed regulating gear 18, the second speed regulating gear 19 and the inner gear ring 23 to rotate synchronously, and at this time, the inner gear ring 23 will drive the rotating carrier disc 3 to rotate synchronously, so as to realize the rotation of the carrier position on the rotating carrier disc 3;

[0028] Furthermore, the diameter of the first speed regulating gear 18 is greater than the diameter of the second speed regulating gear 19 , so under the drive of the second residual gear 16 , the rotation speed of the motor 1 will be reduced to achieve stable rotation of the rotating carrier plate 3 .

[0029] The coaxial reversing mechanism includes an upper gear 5, a lower gear 6, a rotating shaft 7, a first bevel gear 8 and a second bevel gear 9. The upper gear 5 and the lower gear 6 are fixedly arranged at the top and the bottom of the rotating shaft 7. A group of second bevel gears 9 are fixedly arranged on the opposite surfaces of the upper gear 5 and the lower gear 6. A group of second bevel gears 9 are all meshed with the first bevel gear 8. The first residual gear 4, the third residual gear 20 and the upper gear 5 are meshed on the same horizontal plane, and the fourth residual gear 21 and the lower gear 6 are meshed on the same horizontal plane, that is, the first residual gear 4 is first meshed with the upper gear 5, and then the upper gear 5 is meshed and rotated with the inner teeth of the gear ring 10, thereby driving the gear ring 10 to rotate, thereby realizing the movement of the subsequent plug 13.

[0030] When the first residual gear 4 and the second residual gear 16 are both meshed, the continuously rotating rotating column 22 will drive the third residual gear 20 to contact and rotate with the coaxial reversing mechanism, and the third residual gear 20 will contact and rotate with the upper gear 5, and then the gear ring 10 will rotate, and the first composite gear 11 meshed with the gear ring 10 will rotate accordingly, thereby driving the second composite gear 12 to rotate synchronously. When the second composite gear 12 rotates, the plug-in block 13 matched with the second composite gear 12 continues to move outward on the original basis. When the third residual gear 20 finishes meshing, the press-self-locking mechanism 14 is squeezed and unlocked, and pops out. At this time, the rotating column 22 drives the fourth residual gear 21 to contact and mesh with the coaxial reversing mechanism, and the press-self-locking mechanism 1 4 is released slowly to reduce the influence of the elastic force on the positioning accuracy. The fourth residual gear 21 contacts and rotates with the lower gear 6. At this time, the rotation of the lower gear 6 is transmitted through the meshing of the first bevel gear 8 and the second bevel gear 9 to control the upper gear 5 to rotate in the opposite direction, thereby driving the gear ring 10 to rotate synchronously. The first composite gear 11 meshing with the gear ring 10 rotates accordingly, thereby driving the second composite gear 12 to rotate synchronously. When the second composite gear 12 rotates, the plug block 13 matched with the second composite gear 12 moves inwardly. A slot 15 is provided on the outer wall of the fixing seat 24. The shape and size of the slot 15 match the shape and size of the plug block 13. When the plug block 13 is inserted into the slot, the positioning of the rotating carrier disc 3 is completed.

[0031] After the fourth residual gear 21 completes the meshing, the fifth residual gear 25 contacts and meshes with the gear column 17. At this time, the motor 1 stops rotating, and the plug block 13 is not fully inserted into the slot. Instead, the remaining positioning is completed by the elastic force of the pressing self-locking mechanism 14. When the pointed bevel at one end of the plug block 13 is inserted into the slot, an extrusion force is applied to the fixed seat 24. This extrusion force pushes the fixed seat 24 and the rotating column 22 to rotate, and the position of the fixed seat 24 is adjusted so that the plug block 13 can smoothly and completely insert the pointed bevel into the slot. During the adjustment process of the fixed seat 24 and the rotating column 22, the fifth residual gear 25 will rotate synchronously, and the rotation angle of the rotating carrier plate 3 can be further fine-tuned in conjunction with the speed regulating mechanism.

[0032] The above structure changes the rotational force of the motor 1 into three stages, one stage is controlled by the first residual gear 4 to unlock, one stage is controlled by the second residual gear 16 to rotate the rotating carrier plate 3, and one stage is used by the third residual gear 20, the fourth residual gear 21 and the fifth residual gear 25 to position and fine-tune the rotating carrier plate 3, which effectively prevents the motor 1 from controlling the rotation alone, and the error will cause the welding position deviation to occur.

[0033] The gears mentioned in the schematic diagram of the present invention are schematic diagrams, which are well known and understood by those skilled in the art, so the meshing conditions between specific teeth are not drawn.

[0034] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention.
