Description

Technical Field

[0001] This invention relates to the field of laser processing technology, and specifically to a laser cutting device for treating burrs on battery box housings. Background Technology

[0002] The basic function of a battery box is to house and protect the battery pack. The structure must ensure sufficient strength while retaining the maximum housing space. Battery boxes are usually designed using a frame structure, that is, the frame and bottom frame are made of welded profiles with a recommended material thickness of >3mm. The outer or double-sided skin of the profiles is welded. The shape of the battery box is preferably a regular cuboid, which can be adjusted appropriately according to the layout requirements.

[0003] During the manufacturing process, the battery box casing typically requires the use of laser cutting equipment. Laser cutting utilizes a focused high-power-density laser beam to irradiate the workpiece, causing the irradiated material to rapidly melt, vaporize, or reach its ignition point. Simultaneously, a high-speed airflow coaxial with the beam blows away the molten material, thereby cutting the workpiece. It is one of the thermal cutting methods for cutting workpieces and is divided into four categories: laser vaporization cutting, laser melting cutting, laser oxygen cutting, and laser scribing and controlled fracture.

[0004] Chinese Patent No. CN223431115U discloses a laser cutting and positioning device for a battery box cover, comprising a base plate, a positioning fixture fixedly mounted on the base plate for positioning and placing the battery box cover, and multiple pressing mechanisms disposed around the positioning fixture for pressing the rough edges of the battery box cover. Each pressing mechanism includes a base fixedly mounted on the base plate, a rotary pressing cylinder, a lower connecting plate, a lower support rod, an upper swing arm, and an upper pressing block. The base is fixedly mounted on the base plate, the rotary pressing cylinder is fixedly mounted on the base, the lower connecting plate is fixedly mounted on the cylinder body of the rotary pressing cylinder, and the lower support rod is fixedly mounted on the lower connecting plate for supporting the lower surface of the rough edges. The upper swing arm is fixedly mounted on the piston rod of the rotary pressing cylinder, and the upper pressing block is fixedly mounted on the upper swing arm. The piston rod of the rotary pressing cylinder has two strokes: rotation and linear pressing. During the rotation and pressing of the piston rod, the upper pressing block can rotate to above the burr and press down onto the upper surface of the burr, thereby horizontally positioning the burr. At least one support column for limiting the downward position of the upper swing arm is also fixedly mounted on the cylinder body of the rotary pressing cylinder. The positioning fixture includes a fixture bracket and four corner positioning parts fixedly mounted on the fixture bracket. The four corner positioning parts are distributed at the four corners of the cuboid and are used to position the battery box cover.

[0005] When processing the battery box cover, first place the battery box cover on the four corner positioning parts of the positioning fixture to position the outline of the battery box cover. Start each pressing mechanism. The upper pressing block first rotates to above the burr and then descends to press the upper surface of the burr. With the cooperation of the lower support rod, the burr is positioned horizontally. Then, the inner support assembly is placed into the battery box cover to hold the inner wall of the battery box cover and complete the positioning. Finally, start the laser cutting equipment to cut. After the cutting is completed, take out the inner support assembly, rotate the lower pressing cylinder to reset in the opposite direction, and the upper pressing block first rises and then swings to the side. In this way, the burr and the battery box cover can be removed.

[0006] In the aforementioned technologies, a large amount of slag is generated during the laser cutting process. The slag easily adheres to the upper surface of the workpiece and solidifies there, leaving marks on the workpiece and even causing unevenness on the surface of the battery box shell, resulting in poor processing quality of the battery box shell. Summary of the Invention

[0007] This invention provides a laser cutting device for treating burrs on battery box housings, aiming to solve the technical problem that during the processing of laser cutting equipment in related technologies, a large amount of slag is generated. The slag easily adheres to the upper surface of the workpiece and solidifies on the upper surface of the workpiece, easily leaving marks on the workpiece. In more serious cases, it can cause unevenness on the surface of the battery box housing, resulting in poor processing quality of the battery box housing.

[0008] A laser cutting device for burr removal of battery box housings according to the present invention includes a frame, a laser cutting mechanism disposed on the frame, and a conveying mechanism disposed on the frame. A receiving platform for receiving workpieces is rotatably mounted on the frame. A cleaning device is disposed on the receiving platform. The cleaning device includes a support frame rotatably mounted on the frame, and a first cleaning plate and a second cleaning plate disposed on the support frame. Both the first and second cleaning plates are slidably and rotatably mounted on the support frame. The rotation speed of the support frame is lower than the rotation speed of the receiving platform. The first and second cleaning plates are arranged opposite to each other and are used to clean slag from the workpiece. A connecting device is disposed on the support frame for the second cleaning plate to drive the first cleaning plate to slide. A driver is disposed on the support frame for driving the first and second cleaning plates to slide radially along the receiving platform. When the workpiece rotates between the first and second cleaning plates, the first and second cleaning plates clamp the side of the workpiece. The driver drives the first and second cleaning plates to slide, cleaning the side of the workpiece.

[0009] Beneficial effects: By setting up the cleaning device, when the workpiece arrives at the receiving table from the conveyor, it is adsorbed by the suction cups on the receiving table. Then, the receiving table drives the workpiece to rotate, and the support frame rotates at the same time. The rotation speed of the support frame is lower than that of the receiving table. When the workpiece rotates to the cleaning plate, the slag on the upper surface of the workpiece is first scraped off by the first cleaning plate. The workpiece continues to rotate. When the workpiece passes the first cleaning plate and is located between the first and second cleaning plates, the sides of the workpiece are clamped by the second cleaning plate and the first cleaning plate. The driver is then activated, and the driver drives the first and second cleaning plates to slide back and forth along the radial direction of the receiving table, cleaning the slag on the sides of both ends of the workpiece. This achieves the cleaning of the surface of the workpiece and the slag on the sides of both ends of the workpiece, thereby improving the processing quality of the battery box shell.

[0010] Preferably, the support frame has multiple sliding grooves, and the first cleaning plate and the second cleaning plate are slidably fitted in the sliding grooves. One end of the sliding groove located at the second cleaning plate is set as a circular part, the second cleaning plate is rotatably fitted in the circular part, and the first cleaning plate is rotatably fitted in the support frame.

[0011] Preferably, the connecting device includes a connecting plate disposed on the second cleaning plate, a rotating roller rotatably fitted on the connecting plate, a connecting rope for driving the first cleaning plate to slide, and a rotating mechanism for driving the rotating roller to rotate. One end of the connecting rope is wound around the rotating roller, and the other end is connected to the first cleaning plate.

[0012] Beneficial effects: With the connection device, when the workpiece reaches the second cleaning plate, the side of the workpiece pushes the second cleaning plate to slide. During the sliding process of the second cleaning plate, it passes through the connecting plate and drives the rotating roller to rotate. Through the rotating mechanism, the first cleaning plate slides at the same time, thereby clamping both ends of the workpiece. This makes it convenient to clean the sides of both ends of the workpiece through the first cleaning plate and the second cleaning plate.

[0013] Preferably, the rotating mechanism includes a rotating assembly for driving the rotating roller to rotate and an adjusting assembly for supporting the rotating assembly.

[0014] Beneficial effects: By setting up the rotating and adjusting components, the second cleaning plate can slide while the support frame rotates, and drive the first cleaning plate to slide at the same time to clean the rotating workpiece.

[0015] Preferably, the rotating assembly includes a gear for driving the rotating roller to rotate and a rack meshing with the gear, the gear being rotatably engaged with a connecting plate.

[0016] Preferably, the adjustment assembly includes a support plate and an active telescopic rod mounted on a support frame, the rack being slidably engaged with the support plate, one end of the active telescopic rod being connected to the support plate, and the other end being connected to the rack.

[0017] Preferably, the support frame is provided with a reset device, which includes a sliding component for driving the cleaning plate to slide and reset, and a reset component for driving the cleaning plate to rotate and reset.

[0018] Beneficial effects: With the reset device, when the workpiece moves to a point on the cleaning plate, it can push the first cleaning plate to rotate. After the first cleaning plate rotates, it is reset by the rotating component. When the second cleaning plate moves the first cleaning plate to slide and adjust, the sliding component can reset the first cleaning plate, which facilitates the cleaning of subsequent workpieces and enables continuous cleaning of workpieces.

[0019] Preferably, the sliding assembly includes a mounting plate disposed on the cleaning plate, a sliding rod slidably fitted on the support frame, and an elastic element two mounted on the sliding rod. The sliding rod is connected to the mounting plate, and one end of the elastic element two is connected to the support frame and the other end is connected to the mounting plate.

[0020] Preferably, the reset assembly includes a rotating rod connected to the cleaning plate and rotatably fitted onto the mounting plate, and a torsion spring disposed on the rotating rod for driving the cleaning plate to rotate and reset.

[0021] Preferably, the support frame includes a fixed part rotatably fitted on the frame and a sliding part slidably fitted on the fixed part, and one end of the driver is connected to the fixed part and the other end is connected to the sliding part.

[0022] Beneficial effects: By setting up the sliding part and the fixed part, when the fixed part rotates, it can drive the sliding part to rotate, and then drive the cleaning plate one and the cleaning plate two to rotate. When the driver works, it can drive the sliding part to slide within the fixed part, and the sliding part drives the cleaning plate one and the cleaning plate two to slide, thereby realizing the radial sliding movement of the cleaning plate one and the cleaning plate two along the receiving platform.

[0023] The beneficial effects of this invention are as follows: 1. In this invention, by setting up a cleaning device, when the workpiece arrives at the receiving table from the conveying device, the workpiece is adsorbed by the suction cup on the receiving table. Then, the receiving table drives the workpiece to rotate, and at the same time, the support frame rotates. The rotation speed of the support frame is lower than the rotation speed of the receiving table. When the workpiece rotates to a cleaning plate, the slag on the upper surface of the workpiece is first scraped off by the first cleaning plate. The workpiece continues to rotate. When the workpiece passes the first cleaning plate and is located between the first and second cleaning plates, the sides of the workpiece are clamped by the second cleaning plate and the first cleaning plate. The driver is then activated. The driver drives the first and second cleaning plates to slide back and forth along the radial direction of the receiving table to clean the slag on the sides of both ends of the workpiece. This achieves the cleaning of the surface of the workpiece and the slag on the sides of both ends of the workpiece, thereby improving the processing quality of the battery box shell. 2. In this invention, by setting up a connecting device, when the workpiece reaches the second cleaning plate, the side of the workpiece pushes the second cleaning plate to slide. During the sliding process of the second cleaning plate, it passes through the connecting plate and drives the rotating roller to rotate. Through the rotating mechanism, it drives the first cleaning plate to slide at the same time, thereby clamping both ends of the workpiece. This makes it convenient to clean the sides of both ends of the workpiece through the first cleaning plate and the second cleaning plate. 3. In this invention, by setting a reset device, when the workpiece moves to a cleaning plate, it can push the first cleaning plate to rotate. After the first cleaning plate rotates, the rotating component drives the first cleaning plate to reset. When the second cleaning plate drives the first cleaning plate to slide and adjust, after the adjustment is completed, the sliding component can drive the first cleaning plate to reset, thereby facilitating the cleaning of subsequent workpieces and realizing continuous cleaning of workpieces.

[0041] Reference Figures 2-5 The support frame 51 is provided with a connecting device 6 for the cleaning plate 2 53 to drive the cleaning plate 1 52 to slide. When the workpiece rotates between the cleaning plate 1 52 and the cleaning plate 2 53, the cleaning plate 2 53 and the cleaning plate 1 52 clamp the side of the workpiece.

[0042] Among them, reference Figures 2-5 The connecting device 6 includes a connecting plate 61 disposed on the second cleaning plate 53, a rotating roller 62 rotatably fitted on the connecting plate 61, a connecting rope 63 for driving the first cleaning plate 52 to slide, and a rotating mechanism for driving the rotating roller 62 to rotate. One end of the connecting rope 63 is fixedly connected to the rotating roller 62 and is wound around the rotating roller 62. When the rotating roller 62 rotates, it can wind up the connecting rope 63, and the connecting rope 63 drives the first cleaning plate 52 to slide closer to the second cleaning plate 53. When the rotating roller 62 rotates in the opposite direction, it can unwind the connecting rope 63, and the connecting rope 63 drives the first cleaning plate 52 to slide away from the second cleaning plate 53.

The gear 641 is fixedly connected to the rotating roller 62 and rotates in conjunction with the connecting plate 61. The rack 642 is horizontally set. When the workpiece moves to the second cleaning plate 53 and abuts against the side of the second cleaning plate 53, the workpiece continues to rotate and can push the second cleaning plate 53 to slide. The second cleaning plate 53 drives the connecting plate 61 to slide. The connecting plate 61 drives the gear 641 and the rotating roller 62 to move. During the movement of the gear 641, it can rotate. The gear 641 drives the rotating roller 62 to rotate. When the rotating roller 62 rotates, it winds up the connecting rope 63. The connecting rope 63 pulls the mounting plate 811 to rotate in the slide groove 511. The mounting plate 811 drives the first cleaning plate 52 to slide. The first cleaning plate 52 slides towards the side close to the workpiece.

[0044] Reference Figures 2-5 The adjustment component 65 includes a support plate 651 and an active telescopic rod 652 fixedly mounted on the support frame 51. A rack 642 is slidably engaged with the support plate 651. The support plate 651 is U-shaped. The active telescopic rod 652 is directly a hydraulic cylinder. One end of the active telescopic rod 652 is fixedly connected to the support plate 651, and the other end is fixedly connected to the rack 642. When the first cleaning plate 52 abuts against the side of the workpiece, and the first cleaning plate 52 and the second cleaning plate 53 clamp the sides of both ends of the workpiece, the workpiece drives the first cleaning plate 52 and the second cleaning plate 53 to slide synchronously. Then the active telescopic rod 652 works, and the active telescopic rod 652 can drive the rack 642 to slide, so that the rack 642 slides synchronously with the gear 641. The gear 641 does not rotate. When the second cleaning plate 53 slides to the circular part 512 of the slide groove 511, the cleaning operation on the sides of both ends of the workpiece is completed.

The rotating rod 821 is a "T"-shaped rod. One end of the torsion spring 822 is fixedly connected to the rotating rod 821, and the other end is fixedly connected to the mounting plate 811. When the receiving platform 4 drives the workpiece to rotate to the support frame 51, the side of the workpiece first abuts against the cleaning plate 52. During the rotation of the workpiece, it can squeeze the cleaning plate 52, causing the cleaning plate 52 to rotate and reset. 2. The bottom end of cleaning plate 1 52 rotates towards cleaning plate 2 53, driving the rotating rod 821 to rotate. During the rotation of the rotating rod 821, the torsion spring 822 is compressed. As the workpiece continues to rotate, the bottom end of cleaning plate 1 52 abuts against the workpiece and scrapes off the slag on the upper surface of the workpiece. At the same time, the cleaning brush 11 on the support frame 51 cleans the slag on the upper surface of the workpiece. After the workpiece passes cleaning plate 1 52, the torsion spring 822 releases its elastic restoring force, driving the rotating rod 821 to rotate and driving cleaning plate 1 52 to rotate and reset.

[0047] Reference Figures 7-10 The second cleaning plate 53 is also equipped with a mounting plate 811, a rotating rod 821 and a torsion spring 822. One end of the rotating rod 821 at the second cleaning plate 53 is fixedly connected to the waist-shaped rod.

[0048] The implementation principle of the laser cutting device for treating burrs on battery box shell of the present invention is as follows: when the workpiece needs to be processed, the workpiece is first laser-cut by the laser cutting mechanism 2. After the laser cutting is completed, the workpiece is transported to the receiving platform 4 by the conveying mechanism 3 at the laser cutting mechanism 2. When the workpiece arrives at the receiving platform 4, the suction cup on the receiving platform 4 works and adsorbs and clamps the workpiece. Next, drive component 2 101 is started. Drive component 2 101 can drive bevel gear 1 102 to rotate. Bevel gear 1 102 drives bevel gear 2 103 and drive sleeve 104 to rotate. Drive sleeve 104 drives receiving platform 4 to rotate. Receiving platform 4 drives workpiece to rotate. At the same time, the drive component 91 is activated, which drives the rotating shaft 92 to rotate. The rotating shaft 92 drives the fixed part 513 and the sliding part 514 to rotate. When the receiving platform 4 drives the workpiece to rotate to the support frame 51, the side of the workpiece first abuts against the cleaning plate 52. During the rotation of the workpiece, it can squeeze the cleaning plate 52, causing the cleaning plate 52 to rotate. The bottom end of the cleaning plate 52 rotates towards the cleaning plate 53 and drives the rotating rod 821 to rotate. During the rotation of the rotating rod 821, the torsion spring 822 is compressed. As the workpiece continues to rotate, the bottom end of the cleaning plate 52 abuts against the workpiece and scrapes off the slag on the upper surface of the workpiece. At the same time, the cleaning brush 11 on the support frame 51 cleans the slag on the upper surface of the workpiece. After the workpiece passes the cleaning plate 52, the torsion spring 822 releases its elastic restoring force, drives the rotating rod 821 to rotate, and drives the cleaning plate 52 to rotate and reset. After the first cleaning plate 52 is reset, the workpiece moves to the second cleaning plate 53 and abuts against the side of the second cleaning plate 53. At this time, the workpiece continues to rotate and can push the second cleaning plate 53 to slide. The second cleaning plate 53 drives the connecting plate 61 to slide. The connecting plate 61 drives the gear 641 and the rotating roller 62 to move. During the movement of the gear 641, it can rotate. The gear 641 drives the rotating roller 62 to rotate. When the rotating roller 62 rotates, it winds up the connecting rope 63. The connecting rope 63 pulls the limiting plate 12 to slide. The limiting plate 12 drives the mounting plate 811 to rotate in the slide groove 511. The mounting plate 811 drives the rotating rod 821, the torsion spring 822 and the first cleaning plate 52 to slide. The first cleaning plate 52 slides towards the side close to the workpiece and compresses the second elastic element 813. When the first cleaning plate 52 comes into contact with the side of the workpiece, the first cleaning plate 52 and the second cleaning plate 53 clamp the sides of both ends of the workpiece. The workpiece drives the first cleaning plate 52 and the second cleaning plate 53 to slide synchronously. Then the active telescopic rod 652 works. The active telescopic rod 652 can drive the rack 642 to slide, so that the rack 642 and the gear 641 slide synchronously, and the gear 641 does not rotate. Next, the driver 7 is started. The driver 7 can drive the sliding part 514 to slide within the fixed part 513. During the sliding process of the sliding part 514, the cleaning plate 1 52 and the cleaning plate 2 53 are driven to slide. The driver 7 drives the sliding part 514 to slide back and forth, and drives the cleaning plate 1 52 and the cleaning plate 2 53 to slide back and forth, scraping off the slag at different positions on the sides of both ends of the workpiece. When the waist-shaped rod at the second cleaning plate 53 slides into the circular part 512 of the slide groove 511, the workpiece continues to rotate, which can squeeze the second cleaning plate 53, causing the second cleaning plate 53 to rotate. The second cleaning plate 53 drives the rotating rod 821 to rotate and compresses the torsion spring 822. At this time, the waist-shaped rod rotates in the circular part 512, and the workpiece can pass through the second cleaning plate 53. At this time, the cleaning of the workpiece is completed. When the workpiece moves away from the second cleaning plate 53, the torsion spring 822 releases its elastic restoring force, drives the second cleaning plate 53 to rotate and reset. At the same time, the first cleaning plate 52 and the second cleaning plate 53 slide and reset. At this time, the rotating roller 62 rotates in the opposite direction and unwinds the connecting rope 63. After the slag on the upper surface of the workpiece and the sides of both ends of the workpiece is cleaned by the cleaning device 5, the workpiece is transported out by the conveying mechanism 3 to complete the laser cutting operation of the workpiece.
