Description

Technical Field

[0001] The invention relates to the field of welding carrier processing, in particular to a carrier cooling mechanism for cover plate pole welding. 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. However, in the actual welding process, the carrier where the cover and the pole are located will generate extremely high temperature, so the carrier needs to be cooled. The cooling method is mostly to introduce cooling water, and the corresponding cooling work is carried out through the circulation of cooling water and the heat exchange of the carrier.

[0004] In actual use, in order to improve the welding efficiency of the cover plate and the pole, multiple carriers are often set up, and the cover plate and the pole can be placed on each carrier. When the welding of the cover plate and the pole on one carrier is completed, another carrier is switched for welding. However, each carrier needs to be installed with a separate cooling unit, which places higher requirements on the cooling pipeline and makes the installation more troublesome and inconvenient. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a cooling mechanism for a carrier for welding a cover plate pole, so as to solve the technical problem that the cooling unit of a general carrier for welding a battery cover plate is inconvenient to install.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cooling mechanism for a carrier for welding a cap plate pole, comprising a rotating disk, a cooling disk and a cooling water tank, a movable shell is movably arranged on the top of the cooling water tank, a driving mechanism is installed on the top of the cooling water tank, and the movable shell is controlled to move by the driving mechanism, a water pipe is arranged at the top water outlet of the cooling water tank, the water pipe is connected to the movable shell, a rotating block is rotatably installed at one end inside the movable shell, a water trough is arranged inside the rotating block, through holes are arranged at both ends of the rotating block, the axis of the through hole of the rotating block away from the end of the water pipe is concentric with the axis of the rotating block, the axis of the through hole of the rotating block close to the end of the water pipe is parallel to the axis of the rotating block, the through hole of the rotating block away from the end of the water pipe is connected to the cooling disk, and a rotating mechanism is installed inside the movable shell. .

[0007] The present invention is further configured such that the rotating mechanism includes a rotating wheel and a rack, the rotating wheel is rotatably arranged inside the movable shell, one end of the rotating block and the rotating wheel are both provided with fixed teeth, and the rotating wheel and the rotating block are meshed with each other through the fixed teeth, the outer wall of the cooling plate is fixedly provided with a rack, and the outer wall of the rotating wheel is provided with rotating teeth matching the rack.

[0008] The present invention is further configured such that a through slot is provided on the outer wall of the movable shell, and the shape and size of the through slot match the shape and size of the rack.

[0009] The present invention is further configured such that a cooling groove is opened inside the cooling plate, a diverter block is provided on the inner wall of the cooling groove, both ends of the cooling groove are respectively connected to a one-way valve and a vacuum pump, and the one-way valve is installed at one end of the movable shell, and the vacuum pump is installed at the water inlet end of the cooling water tank.

[0010] The present invention is further configured such that the driving mechanism is a telescopic cylinder, the telescopic cylinder is fixedly mounted on the top of the cooling water tank, the movable end of the telescopic cylinder is connected to a movable shell, a guide block is fixedly provided on the top of the cooling water tank, and a guide groove matching the guide block is provided at the bottom of the movable shell.

[0012] The present invention is further configured such that a rubber sealing layer is provided on the outer wall of the one-way valve and the vacuum pump.

[0013] In summary, the present invention mainly has the following beneficial effects: the cooling water inside the cooling disk of the present invention can cool the cover plate and the pole to be welded. When the cover plate and the pole to be welded are placed on the surface of the cooling disk, the rotating disk rotates the cooling disk to the position of the cooling water tank. At this time, the movable shell is pushed forward, and the rotating block connects the cooling disk with the cooling water tank. The cooling water tank passes the cooling water into the cooling disk through a water pump, and then the corresponding welding work is carried out. The number of cooling disks is multiple, and the corresponding welding work can be carried out in sequence. The cooling water inlet and outlet of the cooling unit are quick-connect sockets, and the connection is convenient and fast. After welding is completed, the movable shell retreats. At this time, the rotating block cooling disk is connected to the outside air through the rotating block, and the cooling water tank pumps the cooling water back through the water pump to complete the cooling water replacement inside the cooling disk. Moreover, since the cooling disk is connected to the outside through the rotating block, when the water pump pumps water, the water inside the cooling disk can be better pumped out to prevent it from remaining inside the cooling disk.

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 cooling mechanism for a carrier used for welding a cover plate pole, such as Figure 1-8 As shown, it includes a rotating disk 1, a cooling disk 2 and a cooling water tank 3. A plurality of cooling disks 2 are installed on the rotating disk 1. Each cooling disk 2 serves as a cover plate pole welding carrier. A cooling groove 15 is opened inside the cooling disk 2. The interior of the cooling groove 15 is filled with cooling water provided by the cooling water tank 3. When welding is performed on the top of the cooling disk 2, the cooling water can effectively reduce the heat generated during welding.

[0025] A movable shell 5 is movably provided on the top of the cooling water tank 3. A driving mechanism is installed on the top of the cooling water tank 3. The driving mechanism is a telescopic cylinder 4, and the movable shell 5 is controlled to move by the telescopic cylinder 4. The telescopic cylinder 4 is fixedly installed on the top of the cooling water tank 3. The movable end of the telescopic cylinder 4 is connected to the movable shell 5. A guide block 13 is fixedly provided on the top of the cooling water tank 3. A guide groove matching the guide block 13 is provided at the bottom of the movable shell 5. When the movable shell 5 needs to move, the telescopic cylinder 4 is started, and the movable end of the telescopic cylinder 4 is extended and retracted, so as to control the movable shell 5 to move forward and backward.

[0026] When the cover plate pole is placed on the cooling disk 2 to prepare for welding, the rotating disk 1 is started, and the cooling disk 2 after the material discharge is completed is controlled to be turned into the welding position, that is, in front of the cooling water tank 3. At this time, the telescopic cylinder 4 is started to push the movable shell 5 forward, and the movable shell 5 abuts the cooling disk 2. The rotating mechanism rotates during the movement of the movable shell 5. The rotating mechanism includes a rotating wheel 7 and a rack 8. The rotating wheel 7 is rotatably arranged inside the movable shell 5. One end of the rotating block 6 and the rotating wheel 7 are both provided with fixed teeth, and the rotating wheel 7 and the rotating block 6 are meshed with each other through the fixed teeth. The outer wall of the cooling disk 2 is fixedly provided with a rack 8, and the outer wall of the rotating wheel 7 is provided with rotating teeth matching the rack 8. The outer wall of the movable shell 5 is provided with a through groove 10, and the shape and size of the through groove 10 are matched with the shape and size of the rack 8. That is, when the movable shell 5 moves forward, the rack 8 is inserted into the interior of the movable shell 5 along the through groove 10, and contacts and meshes with the rotating wheel 7 during the insertion process. The rotating wheel 7 rotates, and the rotating block 6 meshing with the rotating wheel 7 rotates synchronously;

[0027] A water pipe 9 is provided at the top water outlet end of the cooling water tank 3, and a vacuum pump 18 is installed at the water inlet end of the cooling water tank 3. The rotating block 6 is rotatably installed inside the movable shell 5. A water trough 11 is provided inside the rotating block 6. Through holes 12 are provided at both ends of the rotating block 6. The axis line of the through hole 12 at one end of the rotating block 6 away from the water pipe 9 is concentric with the axis line of the rotating block 6, and the axis line of the through hole 12 at one end of the rotating block 6 close to the water pipe 9 is parallel to the axis line of the rotating block 6. When the movable shell 5 abuts against the cooling disk 2, the rotating block 6 rotates the through hole 12 at one end of the water pipe 9 to the water outlet position of the water pipe 9. At this time, the cooling disk 2 is connected to the cooling water tank 3 through the rotating block 6 and the water pipe 9, and the vacuum pump 18 is also inserted into one end of the cooling groove 15 at the same time. At this time, the vacuum pump 18 is started, and the cooling water in the cooling water tank 3 can be pumped into the cooling disk 2 through the pressure difference. When the cooling groove 15 is full of cooling water, the corresponding cover plate pole welding work can be carried out.

[0028] After the welding work of the cover plate pole is completed, the vacuum pump 18 is turned off, and the telescopic cylinder 4 is started at this time. The telescopic cylinder 4 pulls the movable shell 5 back, and the rotating wheel 7 meshing with the rack 8 rotates in the opposite direction, thereby driving the rotating block 6 to rotate in the opposite direction, so that the rotating block 6 is separated from the water outlet position of the water pipe 9. At this time, the cooling disk 2 is no longer connected with the cooling water tank 3 through the rotating block 6, but is connected with the outside air, and the vacuum pump 18 is not completely separated from the cooling disk 2. At this time, the telescopic cylinder 4 stops, and the vacuum pump 18 is started again. The vacuum pump 18 completely draws the cooling water in the cooling tank 15 into the cooling water tank 3. Since the cooling disk 2 is connected with the outside air, when the vacuum pump 18 is running, the air will push the remaining cooling water in the cooling tank 15 into the vacuum pump 18, which effectively prevents the cooling water from remaining in the cooling tank 15 and leaking when the rotating disk 1 rotates;

[0029] When the cooling water inside the cooling disk 2 is completely pumped out, the movable end of the telescopic cylinder 4 is completely retracted. At this time, the rack 8 is completely detached from the movable shell 5, and the rotating disk 1 starts to rotate, and the cooling disk 2 that has completed the cover plate pole welding and cooling water cleaning is turned away. The next cooling disk 2 to be welded comes to the welding position, which effectively improves the welding efficiency of the cover plate pole, and each cooling unit adopts a quick-insert structure, which only needs to be turned to the corresponding position to carry out subsequent water supply work, and does not require multiple pipelines to be connected.

[0030] Furthermore, the inner wall of the cooling trough 15 is provided with a diverter block 16, which can evenly distribute the water flow inside the cooling trough 15 into different channels, and after the air enters, the air can completely push out the cooling water in the cooling trough 15 without the action of the diverter block 16. The two ends of the cooling trough 15 are respectively connected to the one-way valve 17 and the vacuum pump 18, and the one-way valve 17 is installed at one end of the movable shell 5, and the vacuum pump 18 is installed at the water inlet end of the cooling water tank 3. Under the action of the one-way valve 17, the vacuum pump 18 can ensure that the cooling water can move in the same direction during operation without leakage, and the outer walls of the one-way valve 17 and the vacuum pump 18 are provided with a rubber sealing layer, so as long as the one-way valve 17 and the vacuum pump 18 are inserted into a part of the cooling trough 15, they can play the corresponding role.

[0031] A cooling device 14 is installed on one side of the cooling water tank 3. The cooling device 14 is a common cooling mechanism that can effectively cool the cooling water inside the cooling water tank 3. Those skilled in the art can select a suitable device for use.

[0032] Furthermore, a one-way water valve is installed inside the through hole 12 of the rotating block 6 close to one end of the water pipe 9, so that after the through hole 12 leaves the water pipe 9, the cooling water will not leak.

[0033] 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. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
