Description

A laser cutting device for battery box production Technical Field

[0001] This utility model belongs to the field of battery box production technology, specifically referring to a laser cutting device for battery box production. Background Technology

[0002] Existing laser cutting equipment used in battery box production generates lasers that can harm the operator's eyes, and the dust and exhaust fumes produced can have health effects if inhaled over a long period of time. In addition, if the debris generated during laser cutting is left on the equipment, it will interfere with the operation of laser cutting. Finally, the debris and exhaust fumes are not filtered, collected and discharged properly. Summary of the Invention

[0003] This invention overcomes the shortcomings of existing technologies and provides a laser cutting device for battery box production. The laser working area is equipped with an outer shell to prevent laser radiation from affecting the operator. The conveyor belt has V-shaped guide grooves at both ends to guide the cutting debris from the conveyor belt to both sides. The motor output shaft simultaneously drives the actuator and the blade to rotate. The rotation of the actuator causes the blade to vibrate, discharging the debris into the debris collection tank. At the same time, the rotation of the blade generates an adsorption airflow, which guides the smoke and exhaust gas into the exhaust gas chamber. There is a baffle separating the two debris collection tanks and the exhaust gas chamber to separate and filter the debris from the exhaust gas.

[0004] The technical solution adopted by this utility model is as follows:

[0005] The present invention discloses a laser cutting device for battery box production, comprising a housing and a first rotating shaft and a second rotating shaft rotatably connected to the inner wall of the housing. A conveyor belt is horizontally wound between the first rotating shaft and the second rotating shaft. A bracket is also fixedly provided on the inner wall of the housing, and the outer wall of the bracket is in contact with the first rotating shaft and the second rotating shaft.

[0006] Furthermore, a laser cutter and a guide groove are fixedly installed on the inner wall of the outer casing, with the guide groove attached to the conveyor belt and located behind the laser cutter.

[0007] Furthermore, two levers are symmetrically distributed and rotated on both sides of the outer wall of the bracket, and a spring connects the levers to the bracket. The levers are located next to the guide groove.

[0008] Furthermore, two baffles are vertically fixed on the bottom wall of the outer shell. The two baffles and the inner side wall of the outer shell form a debris collection trough, and the space between the two baffles forms a waste gas chamber.

[0009] Furthermore, a motor is fixedly installed on the bottom wall of the exhaust gas chamber, and blades and a actuator are coaxially fixed on the output shaft of the motor.

[0010] Furthermore, symmetrical waste discharge covers are provided on both sides of the outer wall of the outer shell, and the waste discharge covers are fitted to the outer shell.

[0011] Furthermore, an exhaust vent is fixedly provided on the front wall of the outer casing, which can discharge the collected exhaust gas to the outside.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The laser working area is encased in a shell to prevent laser beams from affecting the operator.

[0014] The motor output shaft simultaneously drives the toggle and the impeller to rotate, and the rotation of the toggle causes the paddle to vibrate.

[0015] (3) The conveyor belt has figure-eight guide grooves at both ends, which can guide the slag produced by cutting from the conveyor belt to both sides, and then fall into the slag collection groove under the action of the paddle.

[0016] (4) When the blades are working, they can generate an adsorption airflow to guide the dust and exhaust gas produced to the air duct.

[0017] (5) The two slag collection tanks and the air duct are separated from each other to separate and filter the slag from the exhaust gas. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly illustrated below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Embodiments

[0023] Please refer to Figures 1-3. A laser cutting device for battery box production according to this utility model includes a housing 1 and a first rotating shaft 2 and a second rotating shaft 3 rotatably connected to the inner side wall of the housing 1. A conveyor belt 4 is horizontally wound between the first rotating shaft 2 and the second rotating shaft 3. A gap is left between the conveyor belt 4 and the housing 1 to allow debris to pass through.

[0024] A bracket 5 is also fixedly connected between the inner walls of the outer casing 1, and the outer walls at both ends of the bracket 5 are in contact with the first rotating shaft 2 and the second rotating shaft 3.

[0025] The inner wall of the outer casing 1 is also fixed with a laser cutter 6 and a guide groove 7. The guide groove 7 is V-shaped, with the small opening facing the direction of the first rotating shaft 2 and the large opening facing the direction of the second rotating shaft 3, so that the debris generated by cutting can move on both sides of the conveyor belt 4 along with the guide groove 7. The guide groove 7 is attached to the upper wall of the conveyor belt 4 and located behind the laser cutter 6.

[0026] Two levers 8 are symmetrically distributed and rotatably connected on both sides of the outer wall of the bracket 5. A spring 9 is provided between the levers 8 and the bracket 5. The levers 8 are located on the side of the guide groove 7.

[0027] Two baffles 10 are vertically fixed on the bottom wall of the outer shell 1. The two baffles 10 and the inner side wall of the outer shell 1 form a debris collection trough 11, and the two baffles 10 form a waste gas chamber 12.

[0028] A motor 13 is fixedly installed on the bottom wall of the exhaust gas chamber 12. A blade 14 and a lever 15 are coaxially fixed on the output shaft of the motor 13. The blade 14 is located below the lever 15. The lever 15 is long and narrow with two semi-cylindrical protrusions at each end. Two paddles 8 also have two semi-cylindrical protrusions on their surfaces near the lever 15. The paddles 8 are located on the movement path of the lever 15. The lever 15 rotates continuously, pushing the paddles 8 to vibrate up and down continuously.

[0029] Waste discharge cover plates 16 are symmetrically rotated on both sides of the outer wall of the outer shell 1. The waste discharge cover plates 16 are attached to the outer shell 1 and can be rotated open to remove the waste residue accumulated in the waste residue collection tank 11. A waste gas discharge hole 17 is fixedly opened on the front wall of the outer shell 1 to discharge the collected waste gas to the outside.

[0030] The specific implementation method of this embodiment is as follows:

[0031] When the operator performs laser cutting, the item to be cut is placed at the beginning of the conveyor belt 4. The item is transported by the conveyor belt 4 to the laser cutter 6 for cutting. The laser generated by the laser cutter 6 is blocked by the outer casing 1, so it does not affect the operator.

[0032] The slag produced by laser cutting moves forward with the conveyor belt 4 and moves to both sides under the guidance of the guide groove 7. Then, the slag enters the paddle 8 through the gap between the conveyor belt 4 and the outer shell 1. The paddle 8 vibrates up and down under the continuous paddle action of the paddle 15, causing the slag to fall into the slag collection groove 11, thus avoiding the slag remaining on the conveyor belt 4 and interfering with laser cutting.

[0033] Dust and exhaust gas generated by laser cutting are drawn in by the airflow generated by the rotation of blade 14 and flow from the laser cutting area through the gap between conveyor belt 4 and outer shell 1 to the interior of exhaust gas chamber 12.

[0034] The slag is filtered into the slag collection tanks 11 on both sides, and the dust and exhaust gas are filtered into the exhaust gas chamber 12 between the two slag collection tanks 11. After a certain amount is collected, the waste discharge cover 16 is opened to remove the slag from the slag collection tanks 11, and the exhaust gas is discharged from the exhaust gas discharge hole 17.

[0035] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
