Description

Technical Field

[0001] The present invention relates to the technical field of battery case cutting, and in particular to a laser cutting device for processing a battery case. Background Art

[0002] As a core component of new energy vehicles, the processing accuracy of the power battery box structure will directly affect the safety and installation difficulty of the battery pack. Since the battery box is formed by stamping, forging or welding of sheet metal, burrs, flash and dimensional differences will inevitably exist on the edges of the sheet metal. Therefore, after the box is processed into a box, it is necessary to cut along the upper edge.

[0003] Battery cases with different wall thicknesses have significantly different requirements for clamping methods. For thin-walled battery cases, their structural rigidity is relatively weak, and the mechanical clamping method directly applies clamping force through the clamp, which can easily cause the battery case to deform due to excessive local force, affecting the dimensional accuracy of the battery case cutting; for thick-walled battery cases, their structural rigidity is strong and can withstand large clamping forces without being easily deformed. Mechanical clamping can more stably fix the battery case. Therefore, in view of the different requirements for clamping methods for battery cases with different wall thicknesses, it is necessary to provide a laser cutting device that can automatically select mechanical clamping or pneumatic adsorption fixing methods according to the wall thickness of the battery case.

DETAILED DESCRIPTION

[0026] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear herein are based solely on the accompanying drawings and are not intended to limit the present invention.

[0027] Example 1: A laser cutting device for battery box processing, such as Figure 1-Figure 4As shown, it includes a cutting table 10, an adsorption frame 11, an electric suction cup 12, a feed seat 13, a mechanical clamping plate 14, a cutting mechanism and a measuring mechanism. The cutting table 10 is composed of a base located at the lower side and a bracket on the upper side of the base. There are two adsorption frames 11 symmetrically fixed on the cutting table 10. Two electric suction cups 12 are fixedly installed on each adsorption frame 11. The electric suction cups 12 are existing technologies. The electric suction cups 12 fix the box body by vacuum adsorption, and the four electric suction cups 12 are distributed in a square. Two groups of feed seats 13 are connected in a sliding manner along the left and right directions, each group of feed seats 13 consists of two, and the two feed seats 13 in the same group are distributed front to back, and the two feed seats 13 in the same group are commonly fixed with a mechanical clamping plate 14, which fixes the box by mechanical clamping. A cutting mechanism is installed on the cutting table 10, which is used to cut the edge of the top of the box. A measuring mechanism is connected to the cutting table 10, which is used to measure the wall thickness of the box, so that different fixing methods can be selected according to the different wall thicknesses of the box.

[0028] like Figure 1 As shown, the cutting mechanism includes a cutting frame 20, a first slide rail 21, a second slide rail 22, a laser head 23 and an upper electric push rod 24. The cutting table 10 is slidably connected to the cutting frame 20 in the vertical direction. Two first slide rails 21 are fixedly connected to the cutting frame 20 in a left-right symmetrical manner. The two first slide rails 21 are slidably connected to the second slide rails 22 in the front-to-back direction. The laser head 23 is slidably connected to the second slide rails 22 in the left-right direction. The first slide rails 21 and the second slide rails 22 are both electric slide rails in the prior art, and the laser head 23 is also in the prior art. The laser cutting box emitted by the laser head 23, the upper electric push rod 24 is fixedly connected to the cutting table 10, and the telescopic axis of the upper electric push rod 24 is fixedly connected to the cutting frame 20.

[0029] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, the measuring mechanism includes a measuring slide 30, a lever plate 31, an electromagnetic sleeve 32, a pressing rod 33, a No. 1 spring 34, a support seat 35 and a No. 2 spring 36. The cutting table 10 is slidably connected to the support seat 35 in the vertical direction. The support seat 35 is located at the lower side of the cutting frame 20 and is located between the two mechanical splints 14. The support seat 35 is used to carry the box. Four circular holes are distributed in a square shape on the support seat 35. The electric suction cup 12 can pass through the support seat 35 upward through the circular holes. The guide rod to which the support seat 35 and the cutting table 10 are slidably connected is provided with a No. 2 spring 36. When the support seat 35 slides downward, the No. 2 spring 36 is compressed. Four measuring slides are slidably connected to the cutting table 10 in the vertical direction. Rod 30, a spring 34 is sleeved on the measuring slide 30, and the spring 34 will be compressed when the measuring slide 30 moves downward. The lower ends of the two measuring slides 30 on the same side are fixed with a lever plate 31, and an electromagnetic sleeve 32 is connected to the lever plate 31 in a sliding manner along the front and rear directions. The electromagnetic sleeve 32 is a device in the prior art that uses electromagnetic principles and sliding rails to achieve linear motion. The electromagnetic sleeve 32 can slide along the surface of the lever plate 31 under electromagnetic action, and the cutting frame 20 can push the lever plate 31 to move downward through the electromagnetic sleeve 32. A pressing rod 33 is fixed to the lower end of the lever plate 31, and the pressing rod 33 is used to press the box down a fixed distance to judge the wall thickness of the box by the descending distance of the support seat 35.

[0030] When the lifting mechanism 31 is lifted up, the lifting mechanism 32 is lifted up, and the support frame 20 is lifted up, so that the lifting mechanism 31 is lifted up and the lifting mechanism 33 is lifted up, so that the lifting mechanism 31 is lifted up and the lifting mechanism 33 is lifted up. The wall thickness of the box can be known by the height of the drop, and then the electromagnetic slide 32 is controlled to shrink and slide on the lever plate 31. The electromagnetic slide 32 will move under the cutting frame 20, and the compressed No. 1 spring 34 will push the measuring slide 30 and the lever plate 31 to reset upward. When it is detected that the wall thickness of the box is greater than the specified value, the feed seat 13 will move in the direction close to the box, and the mechanical clamps 14 on both sides will clamp and fix the box. When the wall thickness of the box is less than or equal to the specified value, the electric suction cup 12 will adsorb and fix the box, and then start the laser head 23 to start cutting the edge of the top of the box. The laser head 23 can move freely in the horizontal direction through the setting of the first slide rail 21 and the second slide rail 22. After the cutting is completed, the electric suction cup 12 is turned off or the feed seat 13 is controlled to reset, and then the box is removed, and the No. 2 spring 36 will push the support plate 53 to reset upward.

[0031] Example 2: Based on Example 1, Figure 3 、 Figure 6 and Figure 7As shown, it also includes a distribution mechanism that enables different fixing methods according to the measurement results. The distribution mechanism is arranged on the cutting table 10. The distribution mechanism includes a double-layer support plate 40, a lower electric push rod 41, a guide frame 42, an upper push plate 43, a No. 3 spring 44, a pressing plate 45 and an adsorption switch 46. The cutting table 10 is connected to the double-layer support plate 40 in a vertical sliding direction. The double-layer support plate 40 is located on the lower side of the support seat 35. The cutting table 10 is fixed with a lower electric push rod 41. The telescopic axis of the lower electric push rod 41 is fixed to the double-layer support plate 40. There are two guide frames 42 fixed symmetrically on the double-layer support plate 40. The guide frames 42 are all in the left and right directions. The upper push plate 43 is connected to the sliding direction, and the upper push plate 43 can drive the mechanical clamp 14 to clamp the box body when it continues to rise in the extended state. A No. 3 spring 44 is sleeved on the guide rod to which the upper push plate 43 and the guide frame 42 are slidably connected, and one end of the No. 3 spring 44 is fixed to the guide rod of the upper push plate 43, and the other end is fixed to the guide frame 42. A pressing plate 45 is fixed to the upper push plate 43, and an adsorption switch 46 for controlling the opening of the electric suction cup 12 is fixedly installed on the adsorption frame 11 through a bracket. When the upper push plate 43 contracts, the pressing plate 45 will press the adsorption switch 46, and a processing component for controlling the extension and retraction of the upper push plate 43 is provided on the double-layer pallet 40.

[0032] like Figure 1 、 Figure 6 and Figure 7 As shown, the processing assembly includes a contact plate 50, a No. 4 spring 51, a transmission rod 52, a support plate 53, a limit rod 54, a stopper 56 and an expansion rod 57. The double-layer support plate 40 is slidably connected with the contact plate 50 and the transmission rod 52 in the vertical direction. A through hole is provided in the middle of the support seat 35 for the contact plate 50 to pass upward. A No. 4 spring 51 is sleeved on the guide rod to which the contact plate 50 and the double-layer support plate 40 are slidably connected. The upper end of the transmission rod 52 is fixedly connected to the lower end of the contact plate 50, and the lower end of the transmission rod 52 is fixedly connected to the support plate 53. Two symmetrical fixed plates are provided on the support plate 53. There are three limit rods 54 in each group, and a through hole for the limit rods 54 to pass through is provided on the guide frame 42. Three limit holes 55 are provided on each upper push plate 43. The limit rods 54 can be inserted into the limit holes 55 to limit the contraction of the upper push plate 43. Two stoppers 56 are fixed to the upper push plate 43 symmetrically in the front and back. Four expansion rods 57 are fixed to the cutting table 10 through the bracket. The expansion rods 57 are also located on the lower side of the support seat 35. During the upward movement of the upper push plate 43, the expansion rods 57 contact the stoppers 56 to make the upper push plate 43 extend outward from the guide frame 42.

[0033] After the support plate 53 moves downward, it controls the telescopic axis of the lower electric push rod 41 to extend upward, and the double-layer support plate 40 drives the guide frame 42, the upper push plate 43 and the contact plate 50 and other components to move upward. During the upward movement, the stopper 56 will contact the outer side of the expansion rod 57, and the stopper 56 will be squeezed by the expansion rod 57. The outer side refers to the side opposite to the left and right groups of expansion rods 57, so that the upper push plate 43 gradually moves away from the guide frame 42, and the No. 3 spring 44 is compressed. Figure 6It can be seen that a straight portion is provided on the upper side of the expansion rod 57. Since the wall thickness of the box body is greater than the specified value, the support seat 35 and the box body drop more. During the upward movement of the stop block 56 along the straight portion of the expansion rod 57, the resistance plate 50 will contact the outer bottom wall of the box body, and the resistance plate 50 will be resisted by the box body. The resistance plate 50 drives the transmission rod 52 and the support plate 53 to move downward relative to each other, and the limit rod 54 will be inserted into the limit hole 55. When the stop block 56 moves upward and disengages from the expansion rod 57, since the limit rod 54 is located in the limit hole 55, the upper push plate 43 cannot retract, and then the lower electric push rod 41 continues to extend, and the upper push plate 43 continues to move upward to drive the mechanical clamping plate 14 to approach and clamp the box body. After the cutting is completed The control lower electric push rod 41 contracts, and when the upper push plate 43 moves downward, the mechanical clamping plate 14 will release the clamped box body, and since the pressing rod 33 has been reset upward, the No. 2 spring 36 will push the support seat 35 and the box body to reset upward, and the No. 4 spring 51 will push the contact plate 50 to reset upward, thereby driving the limit rod 54 to move out of the limit hole 55 through the transmission rod 52 and the support plate 53, and then the compressed No. 3 spring 44 will push the upper push plate 43 to reset in the direction close to the guide frame 42, and then the lower electric push rod 41 will continue to contract, and the stop block 56 will move along the inner side of the expansion rod 57. The inner side refers to the opposite side of the left and right groups of expansion rods 57. When the stop block 56 is about to move to the straight line part below the expansion rod 57, the expansion rod 57 will The stopper 56 is squeezed inwardly, and the No. 3 spring 44 is stretched. When the stopper 56 moves below the expansion rod 57, the No. 3 spring 44 pushes it to reset, so that the stopper 56 moves to the bottom of the outside of the expansion rod 57, so that the expansion rod 57 can squeeze the stopper 56 outward when the lower electric push rod 41 is extended; when the wall thickness of the box body is less than or equal to the specified value, the height of the support seat 35 is lowered less, and the contact plate 50 will not contact the bottom wall of the box body during the upward movement of the stopper 56 along the straight part of the expansion rod 57, or when the stopper 56 rises to disengage from the expansion rod 57, the contact plate 50 just contacts the bottom wall of the box body, so that the limit rod 54 cannot be inserted into the limit hole 55, and when the stopper 56 moves upward and disengages from the expansion rod 57, the compressed The third spring 44 pushes the upper push plate 43 to reset in the direction close to the guide frame 42, and the pressing plate 45 will press the adsorption switch 46, thereby starting the electric suction cup 12 to adsorb and fix the box. At this time, the lower electric push rod 41 can be controlled to stop extending. After the cutting is completed, the lower electric push rod 41 is controlled to retract, and the pressing plate 45 and the adsorption switch 46 gradually disengage from contact, thereby stopping the electric suction cup 12, and the block 56 will also move downward along the inside of the expansion rod 57 until it is reset downward; it should be noted that the electric suction cup 12 can only be started by pressing the adsorption switch 46 during the extension of the lower electric push rod 41, and the electric suction cup 12 will not be started during the retraction of the lower electric push rod 41. The equipment can be controlled by installing a PLC control system.

[0034] like Figure 3 and Figure 4 As shown, it also includes a pushing seat 60, a feed block 61, a hinge rod 62 and a torsion spring 63. There are two pushing seats 60 symmetrically connected to the sliding connection on the left and right sides of the cutting table 10. The pushing seats 60 slide in the vertical direction. A feed block 61 is provided on the pushing seat 60. One end of the hinge rod 62 is rotatably connected to the feed block 61. The other end of the hinge rod 62 is rotatably connected to the mechanical splint 14 on the same side, and a torsion spring 63 is sleeved on the rotating shaft to which the hinge rod 62 and the feed block 61 are rotatably connected. One end of the torsion spring 63 is fixed to the feed block 61, and the other end of the torsion spring 63 is fixed to the rotating shaft of the hinge rod 62. The hinge rod 62 and its rotating shaft are fixedly connected.

[0035] like Figure 3 As shown, it also includes an adjustment component for adjusting the mechanical clamping range. The adjustment component is connected to the feed seat 13. The adjustment component includes an adjustment seat 70, a No. 1 screw 71 and a No. 1 guide rod 72. The lower side of the feed seat 13 is fixedly connected to the No. 1 guide rod 72. The adjustment seat 70 is slidably connected to the No. 1 guide rod 72. The feed seat 13 is rotatably connected to the No. 1 screw 71. The No. 1 screw 71 and the adjustment seat 70 are threadedly connected.

[0036] When the limit rod 54 is located in the limit hole 55 and the lower electric push rod 41 continues to extend, the upper push plate 43 will push the adjustment seat 70 upward, and the pushing seat 60 and the feed block 61 will move upward through the adjustment seat 70. Since the two ends of the hinged rod 62 are respectively connected to the feed block 61 and the mechanical splint 14 for rotation, and the mechanical splint 14 is slidably set on the cutting table 10 through the feed seat 13, when the adjustment seat 70 and the feed block 61 move upward, the hinged rod 62 will push the mechanical splint 14 to move toward the box body, and the hinged rod 62 will When rotation occurs, the torsion spring 63 will be charged; during the contraction of the lower electric push rod 41, the upper push plate 43 and the adjustment seat 70 are out of contact, the adjustment seat 70 and the push seat 60 move downward under the action of gravity, and the feed block 61 drives the mechanical clamping plate 14 to reset in the direction away from the box body through the hinge rod 62; by rotating the No. 1 screw 71, the distance between the adjustment seat 70 and the push seat 60 can be adjusted, thereby adjusting the timing of the upper push plate 43 to push the adjustment seat 70 upward, so as to delay or advance the clamping of the box body, so that this equipment can be suitable for boxes of various specifications.

[0037] Example 3: Based on Example 2, Figure 2 、 Figure 4 and Figure 8As shown, it also includes a positioning mechanism for positioning the box, the positioning mechanism includes a forward slide 80, a forward push plate 81, a No. 5 spring 82, a sliding seat 83, a guide seat 84, a side push plate 85 and a No. 6 spring 86, and there are two forward slides 80 symmetrically connected to the cutting table 10 for sliding movement in the front and rear directions.

[0038] like Figure 2 、 Figure 4 and Figure 8 As shown, it also includes an expansion frame 90, an axis rod frame 91 and a hanging plate 92 for driving the positioning mechanism. The lower side of the forward slide 80 is fixed with an expansion frame 90. The expansion frame 90 is provided with a protrusion of an isosceles trapezoidal structure. The double-layer support plate 40 is fixed with an axis rod frame 91 symmetrically in front and back. The axis rod frame 91 consists of two straight rods and a rotating shaft.

The shaft frame 91 is used to squeeze the expansion frame 90 inward. The guide seat 84 is fixed with a drooping plate 92. When the upper push plate 43 contracts, the pressing plate 45 will push the drooping plate 92.

[0039] like Figure 4 As shown, a No. 7 spring 93 is also included. The guide seat 84 is slidably arranged on the sliding seat 83 along the left and right directions, and the guide rod connected to the guide seat 84 and the sliding seat 83 is sleeved with a No. 7 spring 93.

[0040] During the upward movement of the double-layer support plate 40, the shaft rod frame 91 will be driven to move upward, and the shaft rod frame 91 will squeeze the drooping plate 92 inward, thereby driving the positive slide 80 and the positive push plate 81 close to the box body, thereby pushing the box body to the center position in the front and rear directions to achieve positioning; when the wall thickness of the box body is greater than the specified value, a mechanical clamping method is adopted, that is, the mechanical clamping plate 14 and the feed seat 13 are close to the box body. It can be seen from the above that the feed seat 13 will drive the side push plate 85 close to the box body through the sliding seat 83, thereby pushing the box body to the center position in the left and right directions to achieve positioning. When the wall thickness of the box body is less than the specified value, an adsorption fixation method is adopted. It can be seen from the above that the limit rod 54 will not be inserted into the limit hole 55, and the upper push plate 43 will move toward the direction of the double-layer support plate 40. To reset, during this process, the pressing plate 45 will push the drooping plate 92 to move, and the drooping plate 92 drives the side push plate 85 to approach the box body through the guide seat 84, and because the guide seat 84 and the sliding seat 83 are slidingly connected, and the guide rod of the guide seat 84 is provided with a No. 7 spring 93, the guide seat 84 will only push the sliding seat 83 and the feed seat 13 to move through the No. 5 spring 82, that is, at this time the mechanical splint 14 will not rigidly clamp the box body to prevent the box body with a smaller wall thickness from being compressed and deformed; because the spring is elastic, the box body may still vibrate slightly during the operation of the machine, which will affect the cutting accuracy, so the buffering effect of the spring is only used in the box positioning stage, and the mechanical splint 14 is directly used to rigidly clamp the box body in the fixing stage.

[0041] like Figure 4 As shown, it also includes a threaded rod 94, the sliding seat 83 and the feed seat 13 are slidingly connected, the threaded rod 94 is rotatably connected to the feed seat 13, and the sliding seat 83 and the threaded rod 94 are threadedly connected, the feed block 61 and the push seat 60 are also slidingly connected, the push seat 60 is also rotatably connected to the threaded rod 94, and the feed block 61 and the threaded rod 94 on the push seat 60 are threadedly connected.

[0042] The clamping range of the mechanical clamping plate 14 and the side push plate 85 can be adjusted by rotating the corresponding threaded rod 94, thereby enhancing the applicability of the equipment.

[0043] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to be illustrative only and not to limit the present invention, which is to be defined by the claims.
