Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery box cutting, and particularly relates to a laser cutting equipment for battery box machining. BACKGROUND

[0002] The machining precision of the box structure of a power battery, which is a core component of a new energy vehicle, directly affects the safety and installation difficulty of the battery pack. Since the battery box is formed by stamping, forging or welding of a plate, burrs, flash and size difference will inevitably exist at the edge of the plate, and thus a cutting is required along the edge of the upper side after the box is formed.

[0003] The requirements of different wall thicknesses of the battery box on the clamping mode are significantly different. For a thin-walled battery box, the structural rigidity is relatively weak, and the mechanical clamping mode directly applies clamping force through a clamp, which is easy to cause the battery box to deform due to excessive local stress, thereby affecting the size precision of the battery box cutting. For a thick-walled battery box, the structural rigidity is strong and can withstand a large clamping force without being easily deformed, and the mechanical clamping mode can more stably fix the battery box. Therefore, it is necessary to provide a laser cutting equipment capable of automatically selecting a mechanical clamping or pneumatic suction fixing mode according to the wall thickness of the battery box.

[0028] As shown in Figure 1 , the cutting mechanism includes cutting frame 20, first slide rail 21, second slide rail 22, laser head 23 and upper electric push rod 24, cutting frame 20 is slidably connected on the cutting table 10 in the vertical direction, two first slide rails 21 are symmetrically fixed on the cutting frame 20, second slide rails 22 are slidably connected on the two first slide rails 21 in the front and back direction, laser head 23 is slidably connected on the second slide rail 22 in the left and right direction, the first slide rail 21 and the second slide rail 22 are electric slide rails in prior art, and the laser head 23 is also prior art, the laser cutting box through the laser emitted by the laser head 23, the upper electric push rod 24 is fixed on the cutting table 10, the extension shaft of the upper electric push rod 24 is fixed with the cutting frame 20.

[0029] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the measuring mechanism includes a measuring slide rod 30, a lever plate 31, an electromagnetic sliding sleeve 32, a pressing rod 33, a first spring 34, a support base 35, and a second spring 36. A support base 35 is slidably connected to the cutting table 10 in the vertical direction. The support base 35 is located below the cutting frame 20 and between two mechanical clamping plates 14. The support base 35 supports the housing. Four circular holes are distributed in a square pattern on the support base 35, through which the electric suction cup 12 can pass upwards. A second spring 36 is fitted on the guide rod slidably connected to the support base 35 and the cutting table 10. When the support base 35 slides downwards, it compresses the second spring 36. Four measuring slide rods are slidably connected to the cutting table 10 in the vertical direction. A measuring slide rod 30 is fitted with a first spring 34. When the measuring slide rod 30 moves downward, the first spring 34 is compressed. The lower ends of the two measuring slide rods 30 on the same side are fixedly connected to a lever plate 31. An electromagnetic sliding sleeve 32 is slidably connected to the lever plate 31 in the front-back direction. The electromagnetic sliding sleeve 32 is a device that uses electromagnetic principles and sliding tracks to achieve linear motion in the prior art. The electromagnetic sliding sleeve 32 can slide along the surface of the lever plate 31 under electromagnetic action. The cutting frame 20 can push the lever plate 31 downward through the electromagnetic sliding sleeve 32. A pressing rod 33 is fixedly connected to the lower end of the lever plate 31. The pressing rod 33 is used to press the box body downward by a fixed distance so as to determine the wall thickness of the box body by the descent distance of the support seat 35.

[0030] When using this equipment, place the battery box to be cut onto the support base 35. When the support base 35 is not lowered, its top wall and the cutting table 10 are at the same level, meaning the bottom wall of the outer casing and the cutting table 10 are also at the same level. Then, control the upper electric push rod 24 to extend. During the downward movement of the cutting frame 20, it will press the electromagnetic sliding sleeve 32, pushing the lever plate 31 and the pressing rod 33 downward synchronously. The first spring 34 will be compressed. When the pressing rod 33 contacts the bottom wall inside the casing, continue to control the upper electric push rod 24 to extend. The pressing rod 33 pushes the support base 35 and the casing downward, compressing the second spring 36. When the lower end of the pressing rod 33 is at the same plane as the cutting table 10, the upper electric push rod 24 will stop extending. At this time, the inner bottom wall of the casing is also at the same plane as the cutting table 10. The upper electric push rod 24 will stop extending when the lower end of the support base 35 is at the same level. The wall thickness of the box can be determined by the height of descent. Then, the electromagnetic sliding sleeve 32 is controlled to retract and slide onto the lever plate 31. The electromagnetic sliding sleeve 32 will move away from the cutting frame 20. The compressed spring 34 will push the measuring slide rod 30 and the lever plate 31 to reset upwards. When the wall thickness of the box is detected to be greater than the specified value, the feed seat 13 will move towards the box. 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 attract and fix the box. Then, the laser head 23 will 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 will be turned off or the feed seat 13 will be controlled to reset. Then, the box will be removed, and the second spring 36 will push the support plate 53 to reset upwards.

[0031] Example 2: Based on Example 1, such as Figure 3 , Figure 6 and Figure 7As shown, it also includes a distribution mechanism that activates different fixing methods based on measurement results. The distribution mechanism is set on the cutting table 10 and 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 a suction switch 46. The double-layer support plate 40 is slidably connected to the cutting table 10 in the vertical direction. The double-layer support plate 40 is located below the support base 35. The lower electric push rod 41 is fixed to the cutting table 10. The telescopic shaft of the lower electric push rod 41 is fixed to the double-layer support plate 40. Two guide frames 42 are symmetrically fixed to the double-layer support plate 40. The guide frames 42 are both oriented in the left and right directions. An upper push plate 43 is slidably connected to the upper push plate 43. When the upper push plate 43 is extended and continuously rising, it can drive the mechanical clamping plate 14 to clamp the box. A No. 3 spring 44 is sleeved on the guide rod that is slidably connected to the upper push plate 43 and the guide frame 42. 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. An adsorption switch 46 for controlling the opening of the electric suction cup 12 is fixedly installed on the adsorption frame 11 by a bracket. When the upper push plate 43 retracts, the pressing plate 45 will press the adsorption switch 46. A processing component for controlling the extension and retraction of the upper push plate 43 is provided on the double-layer support plate 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 limiting rod 54, a stop block 56, and an expansion rod 57. The contact plate 50 and the transmission rod 52 are slidably connected vertically to the double-layer support plate 40. A through hole is provided in the middle of the support base 35 for the contact plate 50 to pass upwards. A No. 4 spring 51 is sleeved on the guide rod slidably connected to the contact plate 50 and the double-layer support plate 40. The upper end of the transmission rod 52 is fixedly connected to the lower end of the contact plate 50. The lower end of the transmission rod 52 is fixedly connected to the support plate 53. Two springs are symmetrically fixed to the support plate 53. There are three limit rods 54 in each group. The guide frame 42 has through holes for the limit rods 54 to pass through. Each push plate 43 has three limit holes 55. The limit rods 54 can be inserted into the limit holes 55 to limit the retraction of the push plate 43. Two stops 56 are fixedly connected to the push plate 43 symmetrically. Four expansion rods 57 are fixedly connected to the cutting table 10 through a bracket. The expansion rods 57 are also located on the lower side of the support base 35. During the upward movement of the push plate 43, the expansion rods 57 abut against the stops 56 to make the push plate 43 extend outward from the guide frame 42.

[0033] After the support plate 53 moves downward, the telescopic axis of the lower electric push rod 41 extends upward, causing the double-layer support plate 40 to drive the guide frame 42, upper push plate 43, and contact plate 50 to move upward. During the upward movement, the stop block 56 contacts the outer side of the expansion rod 57, and the stop block 56 is squeezed by the expansion rod 57. The outer side refers to the side of the two sets of expansion rods 57 that are opposite to each other, causing the upper push plate 43 to gradually move away from the guide frame 42. The third spring 44 is compressed, from Figure 6As can be seen, the upper side of the expansion rod 57 has a straight section. Because the wall thickness of the housing exceeds the specified value, the support base 35 and the housing descend significantly. During the upward movement of the stop block 56 along the straight section of the expansion rod 57, the contact plate 50 contacts the outer bottom wall of the housing and is resisted by the housing. The contact plate 50 drives the transmission rod 52 and support plate 53 to move downwards relative to each other. The limiting rod 54 inserts into the limiting hole 55. When the stop block 56 moves upwards and disengages from the expansion rod 57, the upper push plate 43 cannot retract because the limiting rod 54 is located within the limiting hole 55. Then, the lower electric push rod 41 continues to extend, and the upper push plate 43 continues to move upwards, causing the mechanical clamping plate 14 to approach and clamp the housing. After cutting is completed... When the lower electric push rod 41 retracts, the upper push plate 43 moves downward, and the mechanical clamping plate 14 releases the clamped box. Since the pressing rod 33 has already returned to its upward position, the second spring 36 pushes the support seat 35 and the box to return to their upward position. The fourth spring 51 pushes the abutment plate 50 to return to its upward position. This, through the transmission rod 52 and the support plate 53, drives the limiting rod 54 to move out of the limiting hole 55. Then, the compressed third spring 44 pushes the upper push plate 43 to return to its original position closer to the guide frame 42. Then, the lower electric push rod 41 continues to retract, and the stop block 56 moves along the inner side of the expansion rod 57. The inner side refers to the opposite side of the left and right sets of expansion rods 57. When the stop block 56 is about to move to the straight part under the expansion rod 57, the expansion rod 57 will... When the stop block 56 is pressed inward, the third spring 44 is stretched. When the stop block 56 moves below the expansion rod 57, the third spring 44 pushes it back to its original position, moving the stop block 56 to the outside and below the expansion rod 57, so that when the lower electric push rod 41 extends, the expansion rod 57 can press the stop block 56 outward. When the wall thickness of the housing is less than or equal to the specified value, the support base 35 drops less. During the upward movement of the stop block 56 along the straight section of the expansion rod 57, the abutment plate 50 will not contact the bottom wall of the housing, or when the stop block 56 rises to the point of disengagement from the expansion rod 57, the abutment plate 50 just contacts the bottom wall of the housing, so that the limiting rod 54 cannot be inserted into the limiting hole 55. When the stop block 56 moves upward and disengages from the expansion rod 57, the compressed Spring 44 pushes the upper push plate 43 to return to its original position closer to the guide frame 42. Pressing plate 45 presses suction switch 46, thereby activating electric suction cup 12 to adhere and fix the box. At this time, the lower electric push rod 41 can be controlled to stop extending. After cutting, the lower electric push rod 41 is controlled to retract, and pressing plate 45 and suction switch 46 gradually disengage, thereby stopping electric suction cup 12. The stop block 56 will also move downward along the inside of the expansion rod 57 until it returns to its original position. It should be noted that the electric suction cup 12 can only be activated by pressing suction switch 46 during the extension of the lower electric push rod 41. The electric suction cup 12 will not be activated during the retraction of the lower electric push rod 41. This equipment can be controlled by installing a PLC control system.

[0034] likeFigure 3 and Figure 4 As shown, it also includes a pusher seat 60, a feed block 61, a hinge rod 62, and a torsion spring 63. Two pusher seats 60 are symmetrically slidably connected on the cutting table 10. Both pusher seats 60 slide in the vertical direction. A feed block 61 is provided on the pusher 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 clamping plate 14 on the same side. A torsion spring 63 is sleeved on the rotating shaft rotatably connected to the hinge rod 62 and the feed block 61. One end of the torsion spring 63 is fixedly connected to the feed block 61, and the other end of the torsion spring 63 is fixedly connected 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 assembly for adjusting the mechanical clamping range. The adjustment assembly is connected to the feed seat 13. The adjustment assembly includes an adjustment seat 70, a first screw 71 and a first guide rod 72. A first guide rod 72 is fixedly connected to the lower side of the feed seat 13. The adjustment seat 70 is slidably connected to the first guide rod 72. A first screw 71 is rotatably connected to the feed seat 13. The first screw 71 and the adjustment seat 70 are threadedly connected.

[0036] When the limiting rod 54 is within the limiting hole 55 and the lower electric push rod 41 continues to extend, the upper push plate 43 will push the adjusting seat 70 upward. The adjusting seat 70 will then drive the push seat 60 and the feed block 61 to move upward. Since the two ends of the hinge rod 62 are rotatably connected to the feed block 61 and the mechanical clamping plate 14 respectively, and the mechanical clamping plate 14 is slidably mounted on the cutting table 10 via the feed seat 13, when the adjusting seat 70 and the feed block 61 move upward, they will push the mechanical clamping plate 14 towards the housing via the hinge rod 62. Furthermore, the hinge rod 62 will... When rotation occurs, the torsion spring 63 will be charged; during the retraction of the lower electric push rod 41, the upper push plate 43 and the adjusting seat 70 will disengage, and the adjusting seat 70 and the push seat 60 will move downward under the action of gravity. The feed block 61 will drive the mechanical clamping plate 14 to reset away from the box through the hinge rod 62; by rotating the first screw 71, the distance between the adjusting seat 70 and the push seat 60 can be adjusted, thereby adjusting the timing of the upper push plate 43 pushing the adjusting seat 70 upward, so as to delay or advance the clamping of the box, so that the equipment can be used for boxes of various specifications.

[0037] Example 3: Based on Example 2, such as Figure 2 , Figure 4 and Figure 8As shown, it also includes a positioning mechanism for positioning the box body. 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. Two forward slides 80 are symmetrically connected to the cutting table 10. A forward push plate 81 is slidably connected to the forward slide 80 in the forward direction. A No. 5 spring 82 is sleeved on the guide rod that is slidably connected to the forward push plate 81 and the forward slide 80. A sliding seat 83 is provided on the feed seat 13. A guide seat 84 is provided on the sliding seat 83. A side push plate 85 is slidably connected to the guide seat 84 in the left and right direction. The guide rod of the side push plate 85 can retract into the guide seat 84, and a No. 6 spring 86 is sleeved on its guide rod.

[0038] like Figure 2 , Figure 4 and Figure 8 As shown, it also includes an expansion frame 90, a shaft frame 91, and a lower plate 92 for driving the positioning mechanism. Expansion frames 90 are fixedly connected to the lower side of the forward slide 80. The expansion frames 90 have isosceles trapezoidal protrusions. Shaft frames 91 are symmetrically fixed to the double-layer support plate 40. Each shaft frame 91 consists of two straight rods and a rotating shaft. Figure 6 It can be seen that the rotating shaft is set on the side away from the double-layer support plate 40 on the two straight rods. The shaft frame 91 is used to squeeze the expansion frame 90 inward. The guide seat 84 is fixed with a hanging plate 92. When the upper push plate 43 retracts, the pressing plate 45 will push the hanging plate 92.

[0039] like Figure 4 As shown, it also includes a No. 7 spring 93, and the guide seat 84 is slidably disposed on the sliding seat 83 in the left and right direction. The No. 7 spring 93 is sleeved on the guide rod connected to the guide seat 84 and the sliding seat 83.

[0040] During the upward movement of the double-layer pallet 40, the shaft bracket 91 will move upward, and the shaft bracket 91 will press the lower plate 92 inward, thereby moving the forward slide 80 and the forward push plate 81 closer to the housing, thus pushing the housing to the center position in the front-back direction for positioning. When the wall thickness of the housing is greater than the specified value, mechanical clamping is used, that is, the mechanical clamping plate 14 and the feed seat 13 are close to the housing. As mentioned above, the feed seat 13 will drive the side push plate 85 to be close to the housing through the sliding seat 83, thereby pushing the housing to the center position in the left-right direction for positioning. When the wall thickness of the housing is less than the specified value, adsorption fixing is used. As mentioned above, the limit rod 54 will not be inserted into the limit hole 55, and the upper push plate 43 will move towards the double-layer pallet 40. During the reset process, the pressing plate 45 pushes the lower plate 92 to move. The lower plate 92 drives the side push plate 85 to approach the box body through the guide seat 84. Since the guide seat 84 and the sliding seat 83 are slidably connected, and the guide rod of the guide seat 84 is fitted 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 clamp 14 will not clamp the box body rigidly to prevent the box body with a small wall thickness from being deformed by pressure. Because the spring is elastic, the box body may still vibrate slightly during the machine operation, which will affect the cutting accuracy. Therefore, the buffering effect of the spring is only used in the box body positioning stage, and the mechanical clamp 14 is used to clamp the box body rigidly in the fixing stage.

[0041] like Figure 4 As shown, it also includes a threaded rod 94, a sliding seat 83 and a feed seat 13 which are slidably connected, a threaded rod 94 which is rotatably connected to the feed seat 13, and a threaded connection between the sliding seat 83 and the threaded rod 94. The feed block 61 and the push seat 60 are also slidably connected, and a threaded rod 94 is also rotatably connected to the push seat 60. The threaded rod 94 on the feed block 61 and 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 that various changes or modifications can be made to the invention without departing from the principles and spirit of the invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for illustrative purposes only and is not intended to limit the invention; rather, the scope of protection is defined by the content of the claims.
