Description

Technical Field

[0001] The invention relates to the technical field of cutting and processing of power distribution cabinets, and in particular to a laser cutting device for processing a power distribution cabinet body.

[0002] A power distribution cabinet is an electrical device that is mainly used for the distribution, control and protection of electric energy in a power system. The cabinet is mainly made of metal, usually aluminum alloy. During the production process, the entire cabinet is usually produced first, and then holes or square openings are cut on the door panel of the cabinet using a laser cutting device as needed for the installation of some panels.

[0003] The existing distribution cabinet laser cutting device includes a distribution cabinet placement table, a laser cutting mechanism and a driving mechanism for driving the laser cutting mechanism to move. When cutting the distribution cabinet, it is necessary to first place the distribution cabinet horizontally on the distribution cabinet placement table, with the surface to be cut facing upward, facing the laser cutting mechanism, and then rely on the driving mechanism to drive the laser cutting mechanism to cut a square opening on the distribution cabinet according to the trajectory set by the program.

[0004] The shortcomings of the existing distribution cabinet laser cutting device are: although the existing distribution cabinet laser cutting device can cut square openings and other openings on the distribution cabinet door panel to facilitate the later installation of panels and other accessories, the distribution cabinet is placed horizontally during the cutting process and the surface to be cut faces upward. Therefore, the waste generated after each cutting is completed will fall directly into the distribution cabinet, and needs to be cleaned up separately later, which increases the process and is also easy to damage the inner wall of the distribution cabinet; although the distribution cabinet can also be set to face the surface to be cut downward and the laser cutting component is in the lower position, after each cutting is completed, the waste will fall directly and easily hit the laser cutting component itself, causing damage. That is, the existing distribution cabinet laser cutting device is not convenient for separating the waste generated when the cutting is completed. Summary of the invention

[0017] In the process of the laser cutting assembly of the present invention moving along the preset cutting track by means of the longitudinal and transverse driving mechanism, the sliding block connected to the laser cutting assembly is convenient to disengage from the slot on the connecting plate due to the circular arc chamfers set on the ends.

In this way, when the electric telescopic rod contracts to drive the laser cutting assembly away from the power distribution cabinet body, the suction cup can move with the laser cutting assembly again, thereby facilitating the removal of waste materials.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1-Figure 9 As shown, a laser cutting device for processing a distribution cabinet body includes a support base 1, a positioning fixture 2 for fixing a distribution cabinet body 3, a laser cutting component 10, and a longitudinal and transverse driving mechanism for driving the laser cutting component 10 to move in space. A support frame 4 is fixedly connected to the support base 1 via a bracket directly above the support base 1, and the positioning fixture 2 is fixedly installed on one side of the support frame 4. It should be noted that the positioning fixture 2 here can be set as a fixed square frame according to actual needs, which is used to specifically clamp a distribution cabinet body 3 of one size, and can also be set to have a fixed side strip on one side and a movable side strip driven by an electric push rod on the other side, so as to facilitate the clamping and fixing of distribution cabinet bodies 3 of various sizes. The vertical and horizontal driving mechanism is fixedly installed above the supporting base 1 through the supporting frame 4. The vertical and horizontal driving mechanism is controlled by the set program to drive the laser cutting assembly 10 to move vertically and horizontally, so as to facilitate cutting of square through holes on the door panel of the power distribution cabinet body 3, so as to facilitate the installation of components such as panels; the device also includes an adsorption mechanism and a waste recovery mechanism; the adsorption mechanism is cooperatively arranged on one side of the laser cutting assembly 10, and the adsorption mechanism is used to absorb the waste cut and separated from the power distribution cabinet body 3 by the laser cutting assembly 10, so as to prevent the waste from falling into the inside of the power distribution cabinet body 3, which needs to be processed later, and may also damage the inner wall of the power distribution cabinet body 3; The waste recovery mechanism is arranged below the adsorption mechanism, and the waste recovery mechanism is used to receive the waste adsorbed by the adsorption mechanism; the longitudinal and transverse driving mechanism also includes an electric telescopic rod 6 for driving the laser cutting assembly 10 to approach or move away from the distribution cabinet body 3, and a linkage compression mechanism is provided between the telescopic end of the electric telescopic rod 6 and the waste recovery mechanism. When the electric telescopic rod 6 drives the laser cutting assembly 10 that has completed the cutting operation to move away from the distribution cabinet body 3, the electric telescopic rod 6 compresses the waste recovered in the waste recovery mechanism through the linkage compression mechanism, which is convenient for subsequent processing.

[0024] In some specific embodiments, such as Figure 3 As shown, the adsorption mechanism includes a suction cup 11, a connecting straw 23 and a negative pressure pump 9; an automatic disassembly and assembly mechanism is cooperatively connected between the laser cutting component 10 and the connecting straw 23; the suction cup 11 is fixedly arranged at one end of the connecting straw 23, the two are interconnected, and a pressure relief hole 32 is arranged on one side of the suction cup 11, and the pressure relief hole 32 is relatively small; the negative pressure pump 9 is fixedly arranged relative to the laser cutting component 10, and a first movable air guide mechanism connected to the negative pressure end of the negative pressure pump 9 through a tube body is arranged on the laser cutting component 10, and a second movable air guide mechanism is arranged at the other end of the connecting straw 23, and a corrugated metal hose is connected between the first movable air guide mechanism and the second movable air guide mechanism.

[0025] Among them, Figure 4 As shown, the first movable air guide mechanism includes a cylinder 21 and a rotating sleeve 22. The cylinder 21 is fixedly connected to the laser cutting assembly 10. An annular air groove 31 is provided on the cylinder 21. The rotating sleeve 22 is rotatably sleeved on the outside of the cylinder 21, and the rotating sleeve 22 is aligned with the annular air groove 31. The rotating sleeve 22 closes the space where the annular air groove 31 is located when rotating around the cylinder 21. A connecting pipe is fixedly provided on one side of the cylinder 21. The annular air groove 31 is connected to the suction end of the negative pressure pump 9 through the connecting pipe. A connecting hole connected to one end of the corrugated metal hose is provided on one side of the rotating sleeve 22 to facilitate the communication between the corrugated metal hose and the inside of the annular air groove 31.

[0026] In addition, if Figure 5 As shown, the second movable air guide mechanism includes a connecting sleeve 25, which is rotatably sleeved on the end of the connecting straw 23, and an annular protrusion is provided on the outer wall of the end of the connecting straw 23, and an annular groove is provided on the inner wall of the connecting sleeve 25, and the annular protrusion is slidably engaged in the annular groove, and a sealing gasket can be installed inside the annular groove to further ensure the sealing performance, and the connecting sleeve 25 is connected to the end of the corrugated metal hose away from the first movable air guide mechanism.

[0027] Since the connecting sleeve 25 can rotate relative to the connecting suction tube 23, the rotating sleeve 22 can rotate around the cylinder 21 relative to the laser cutting component 10, which makes it convenient for the laser cutting component 10 to rotate relative to the suction cup 11. When the suction cup 11 sucks the distribution cabinet box 3, the laser cutting component 10 can move horizontally and vertically to cut a square hole.

[0028] In some specific embodiments, such as Figures 6 to 8 As shown, the automatic disassembly and assembly mechanism includes a connecting plate 24, a U-shaped frame 26 and an elastic clamp; the connecting plate 24 is fixedly connected to the end of the connecting straw 23 away from the suction cup 11, and both sides of the connecting plate 24 near the top are provided with card slots 34, the U-shaped frame 26 is connected with the laser cutting assembly 10, and two groups of elastic clamps are provided, and are symmetrically arranged at both ends of the U-shaped frame 26, and each group of elastic clamps is respectively matched with the corresponding card slots 34.

[0029] Among them, each group of elastic clamps includes a sliding block 29, a guide sleeve 28 and a connecting spring 30. The guide sleeve 28 is fixedly connected to the end of the U-shaped frame 26. The sliding block 29 slides through the guide sleeve 28. The guide sleeve 28 and the sliding block 29 are both square structures, ensuring that the sliding block 29 can only slide horizontally relative to the guide sleeve 28 and cannot rotate. One end of the sliding block 29 that cooperates with the slot 34 is circumferentially distributed with arc chamfers, that is, when the sliding block 29 is a square block, each edge of its end has been processed with arc chamfers, and when the end of the sliding block 29 is clamped in the slot 34, its arc chamfer is not completely inside the slot 34, and a part of the curved surface of the arc chamfer is outside the slot 34. For details, please refer to Figure 8 As shown; the end of the sliding block 29 away from the slot 34 is connected to the corresponding guide sleeve 28 through a stretchable connecting spring 30. It should be noted that when the end of the sliding block 29 is stuck in the slot 34, the connecting spring 30 is still in a stretched state and has not been completely released.

[0030] When laser cutting is required, the laser cutting assembly 10 is moved close to the switch cabinet body 3, and the point A aligned with the laser cutting assembly 10 is the starting point of laser cutting. At this time, the suction cup 11 is adsorbed on the switch cabinet body 3, and the negative pressure pump 9 is started, so that the suction cup 11 generates negative pressure to fix the point B, and the point B is in the cutting area; then the longitudinal and transverse driving mechanism drives the laser cutting assembly 10 to cut along the cutting track C according to the program control setting. For details, please refer to Fig. 9As shown, during this process, the laser cutting assembly 10 drives the sliding blocks 29 distributed at both ends to move horizontally first through the U-shaped frame 26. Since the suction cup 11 is fixedly adsorbed on the distribution cabinet box 3 at this time, the connecting plate 24 is fixed relative to the distribution cabinet box 3, and the sliding block 29 moves horizontally to one side relative to the connecting plate 24. Since the end of the sliding block 29 inserted into the card slot 34 on the connecting plate 24 is circumferentially distributed with arc chamfers, the sliding block 29 is conveniently subjected to the component force in the sliding direction by relying on the extrusion effect of the inclined surface of the arc chamfer. The sliding block 29 slides relative to the guide sleeve 28 due to the extrusion effect, and slides out of the card slot 34. In this way, the sliding block 29 can slide laterally with the laser cutting component 10 and separate from the entire connecting plate 24, and then the laser cutting component 10 can move and cut along the cutting track C. In this process, since the rotating sleeve 22 is rotatably sleeved on the cylinder 21 connected to the negative pressure pump 9, the rotating sleeve 22 is connected to the connecting sleeve 25 rotatably sleeved on the connecting suction pipe 23 by means of a corrugated metal hose. Therefore, the laser cutting component 10 can move relative to the connecting suction pipe 23 and the suction cup 11, and the negative pressure pump 9 can also be kept connected with the suction cup 11 to ensure that the suction cup 11 is fixedly adsorbed on the material body in the cutting area on the distribution cabinet box 3. The laser cutting component 10 is about to return to the starting point of the laser cutting. When the U-shaped frame 26 is at the starting point A, it is in a state of movement from bottom to top. At this time, the U-shaped frame 26 is just aligned with the sliding blocks 29 at both ends under the card slot 34, and the two sliding blocks 29 are also on both sides of the connecting plate 24. When the U-shaped frame 26 returns to the laser cutting starting point A as the laser cutting assembly 10 rises, the arc chamfered inclined surfaces at the ends of the two sliding blocks 29 are respectively aligned with the two side edge positions of the bottom of the connecting plate 24. When the sliding block 29 is longitudinally raised and squeezed onto the side of the connecting plate 24, the sliding block 29 slides laterally relative to the guide sleeve 28 again due to the squeezing effect, causing the connecting spring 30 to stretch and generate a rebound force. When the laser cutting assembly 10 is again When aligned to the laser cutting starting point A for the second time, the two sliding blocks 29 are just aligned to the position of the slot 34 again, and then the spring 30 is connected to the slot 34 under the action of the rebound force, and then the electric telescopic rod 6 is controlled to shrink, which can drive the laser cutting assembly 10 and the suction cup 11 to move away from the distribution cabinet body 3, so that the suction cup 11 can take the cut waste board out of the distribution cabinet body 3, and then turn off the negative pressure pump 9. Due to the pressure relief hole 32 on the suction cup 11, the suction cup 11 can achieve internal and external air pressure balance without the continuous suction action of the negative pressure pump 9, so that the sucked waste board can fall down and fall into the waste recovery mechanism for recovery.

[0031] In some specific embodiments, such as Figure 6As shown, in order to facilitate the adjustment of the position of the suction cup 11 relative to the laser cutting assembly 10, a slider 33 is fixedly provided on one side of the U-shaped frame 26. The slider 33 passes through the square rod 27 horizontally, and the square rod 27 is fixedly connected to the laser cutting assembly 10. The slider 33 slides horizontally along the square rod 27, and a fastening bolt for fixing the relative position of the square rod 27 and the slider 33 is threadedly connected on the slider 33. The slider 33 can be slid along the square rod 27 to adjust the position of the suction cup 11 relative to the laser cutting assembly 10.

[0032] In some specific embodiments, such as Figure 1 As shown, the longitudinal and transverse driving mechanism includes a vertical electric guide rail 5 and a horizontal electric guide rail 35. The vertical electric guide rail 5 exists in pairs and is fixedly connected to one side of the support base 1 through a support frame 4. The electric telescopic rod 6 is slidably connected to the vertical electric guide rail 5 through a slide seat. The electric telescopic rod 6 moves up and down longitudinally along the vertical electric guide rail 5. The telescopic end of the electric telescopic rod 6 is fixedly connected to a mounting block. The telescopic end of the electric telescopic rod 6 is fixedly connected to the horizontal electric guide rail 35 through the mounting block, and the horizontal electric guide rail 35 and the vertical electric guide rail 5 are perpendicular to each other. The laser cutting assembly 10 is slidably connected to the horizontal electric guide rail 35. When the electric telescopic rod 6 moves longitudinally along the vertical electric guide rail 5, the laser cutting assembly 10 moves longitudinally accordingly. The laser cutting assembly 10 can also move laterally along the horizontal electric guide rail 35; thereby facilitating the longitudinal and transverse movement of the laser cutting assembly 10 to complete the cutting.

[0033] In some specific implementation schemes, in order to facilitate the effective automatic start and stop control of the negative pressure pump 9, one side of the support base 1 is fixedly connected to a support frame through a support frame 4, and the top of the support frame is movably connected to an elastic stop block 36 through a rebound hinge. The elastic stop block 36 is close to the position of the distribution cabinet body 3, and control switches electrically connected to the negative pressure pump 9 are installed on both sides of the elastic stop block 36, and the control switch is laterally aligned with one end of the horizontal electric guide rail 35. The control switch corresponding to the side of the elastic stop block 36 close to the vertical electric guide rail 5 controls the start of the negative pressure pump 9, and the control switch corresponding to the side of the elastic stop block 36 away from the vertical electric guide rail 5 controls the shutdown of the negative pressure pump 9.

[0034] It should be noted that the control switch can be a pressure sensing switch or a push-button switch. After receiving the squeeze, a signal feedback is generated, and the negative pressure pump 9 is started or stopped by relying on the matching controller. That is, a control instruction can be sent once each squeezing, and there is no need to maintain the squeezing state continuously.

[0035] When the electric telescopic rod 6 drives the laser cutting assembly 10 to move laterally close to the distribution cabinet body 3, the horizontal electric guide rail 35 moves together. During this process, the end of the horizontal electric guide rail 35 is squeezed through the position of the elastic stop block 36, and an squeezing effect is produced on the control switch corresponding to the side close to the vertical electric guide rail 5, so that the negative pressure pump 9 starts to generate negative pressure, which facilitates the suction cup 11 to be adsorbed on the distribution cabinet body 3. When the electric telescopic rod 6 contracts and drives the suction cup 11 adsorbing the waste to separate from the distribution cabinet body 3, the end of the horizontal electric guide rail 35 is squeezed through the position of the elastic stop block 36 again, and an squeezing effect is produced on the control switch corresponding to the side away from the vertical electric guide rail 5, so that the negative pressure pump 9 is stopped. At this time, the adsorption effect of the suction cup 11 disappears, thereby facilitating the waste to fall down.

[0036] In some specific embodiments, such as Figure 1 As shown, the waste recovery mechanism includes an inclined guide plate 15 and a storage box 16. The storage box 16 is arranged on the support base 1. The inclined guide plate 15 is fixedly connected to one side of the storage box 16, and the inclined guide plate 15 is located under the adsorption mechanism. When the adsorption effect of the suction cup 11 disappears and the adsorbed waste is released, the waste can fall onto the inclined guide plate 15, and then slide along the inclined guide plate 15 into the storage box 16.

[0037] In some specific embodiments, in combination Figure 1 and Figure 2As shown, the linkage compression mechanism includes a sliding vertical plate 7, a push rod 8, a transmission gear 17 and an extrusion plate 19. The sliding vertical plate 7 is vertically arranged on one side of the electric telescopic rod 6. A fixing frame 12 is fixedly arranged above one side of the support base 1. The fixing frame 12 can be directly fixedly connected to the vertical electric guide rail 5 according to actual installation needs. A guide column 13 is fixedly connected to the inner side of the fixing frame 12 horizontally, and two guide columns 13 are arranged in pairs. The guide column 13 passes through the sliding vertical plate 7, and the sliding vertical plate 7 slides horizontally along the guide column 13. One end of the push rod 8 is fixedly connected to the telescopic end of the electric telescopic rod 6, and the other end is aligned with the sliding vertical plate 7. When the electric telescopic rod 6 moves up and down along the vertical electric guide rail 5, the push rod 8 is aligned with different positions of the sliding vertical plate 7; the transmission gear 17 is rotatably arranged above one side of the support base 1 through a rotating shaft. During specific installation, the transmission gear 17 can be directly connected to the support frame 4 through a horizontal axis. The bottom of the sliding vertical plate 7 is horizontally fixedly connected to the first rack 14, and The first rack 14 is meshed with one side of the transmission gear 17, and the extrusion plate 19 is slidably arranged in the storage box 16. The inner walls on both sides of the storage box 16 can be provided with strip-shaped slide grooves 20. The extrusion plate 19 is slidably connected to the storage box 16 through the strip-shaped slide grooves 20. The extrusion plate 19 is horizontally fixedly connected with a second rack 18 meshed with the other side of the transmission gear 17. When the electric telescopic rod 6 is retracted, it pushes the sliding vertical plate 7 through the push-up action of the ejector rod 8, and the sliding vertical plate 7 slides laterally along the guide column 13 away from the storage box 16, and drives the first rack 14 to move synchronously. The first rack 14 drives the transmission gear 17 to rotate clockwise, and the transmission gear 17 drives the second rack 18 to move in the direction close to the storage box 16. In this way, the second rack 18 pushes the extrusion plate 19 to slide from one side of the storage box 16 to the other side, thereby facilitating the extrusion of the waste falling into the storage box 16, and facilitating the waste to be pressed together, so as to avoid the plate-shaped waste occupying space and being scattered, affecting subsequent processing.

[0038] It should be noted that, generally, the box body 3 of the power distribution cabinet is made of aluminum plate as a whole, and the aluminum material is easy to be deformed by extrusion.

[0039] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios: First, the distribution cabinet body 3 is vertically clamped on one side above the support base 1 through the positioning fixture 2, so that the surface to be cut is in a vertical position and faces the laser cutting assembly 10; Then, the laser cutting assembly 10 is made to move closer to the switch cabinet body 3 by means of the extension of the electric telescopic rod 6 , and the starting position of the cutting is adjusted by means of the driving of the vertical electric guide rail 5 and the horizontal electric guide rail 35 .

[0040] When point A, to which the laser cutting assembly 10 is aimed, is the starting point of laser cutting, the suction cup 11 is adsorbed on the cabinet body 3 of the power distribution cabinet, and the negative pressure pump 9 is in the starting state, so that the suction cup 11 generates negative pressure to fix and adsorb point B, and point B is in the cutting area; then the vertical electric guide rail 5 and the horizontal electric guide rail 35 drive the laser cutting assembly 10 to cut along the cutting track C according to the program control setting. During this process, the laser cutting assembly 10 drives the sliding blocks 29 distributed at both ends to move horizontally first through the U-shaped frame 26. Since the suction cup 11 is fixedly adsorbed on the cabinet body 3 of the power distribution cabinet at this time, the connecting plate 24 is fixed relative to the cabinet body 3, and the sliding block 29 is relative to the connecting plate 24 moves horizontally to one side. Since the end of the sliding block 29 inserted into the slot 34 on the connecting plate 24 is circumferentially distributed with arc chamfers, the sliding block 29 is conveniently subjected to the component force in the sliding direction by the extrusion effect of the inclined surface of the arc chamfer. The sliding block 29 slides relative to the guide sleeve 28 due to the extrusion effect and slides out of the slot 34. In this way, the sliding block 29 can slide horizontally with the laser cutting component 10 and separate from the entire connecting plate 24. Then the laser cutting component 10 can move and cut along the cutting track C. In this process, the rotating sleeve 22 is rotatably sleeved on the cylinder 21 connected to the negative pressure pump 9. The rotating sleeve 22 is connected to the rotating sleeve on the connecting plate 21 by a corrugated metal hose. The connecting sleeve 25 on the suction pipe 23, so the laser cutting component 10 can move relative to the connecting suction pipe 23 and the suction cup 11, and the negative pressure pump 9 can also be kept in communication with the suction cup 11 to ensure that the suction cup 11 is fixedly adsorbed on the material body in the cutting area on the distribution cabinet box 3. When the laser cutting component 10 is about to return to the laser cutting starting point A, it is in a moving state from bottom to top. At this time, the U-shaped frame 26 is just aligned with the sliding blocks 29 at both ends under the card slot 34, and the two sliding blocks 29 are also on both sides of the connecting plate 24. When the U-shaped frame 26 is raised along with the laser cutting component 10 and returns to the laser cutting starting point A, the arc chamfered inclined surfaces at the ends of the two sliding blocks 29 are divided When the sliding block 29 is aligned with the edge positions on both sides of the bottom of the connecting plate 24, the sliding block 29 rises longitudinally and squeezes onto the side of the connecting plate 24. The sliding block 29 slides laterally relative to the guide sleeve 28 again due to the squeezing effect, causing the connecting spring 30 to stretch and generate a rebound force. When the laser cutting component 10 is aligned to the laser cutting starting point A again, the two sliding blocks 29 are just aligned to the position of the slot 34 again, and then the connecting spring 30 is inserted into the slot 34 under the action of the rebound force, and then the electric telescopic rod 6 is controlled to shrink, which can drive the laser cutting component 10 and the suction cup 11 to move away from the distribution cabinet body 3, so that the suction cup 11 can take the cut waste board out of the distribution cabinet body 3.

[0041] During the contraction of the electric telescopic rod 6, the negative pressure pump 9 stops working. Since there is a pressure relief hole 32 on the suction cup 11, the suction cup 11 can achieve internal and external air pressure balance without the continuous suction action of the negative pressure pump 9, so that the sucked waste plate can fall down, fall onto the inclined guide plate 15, and then slide along the inclined guide plate 15 into the storage box 16.

[0042] When the electric telescopic rod 6 is retracted, the sliding vertical plate 7 is pushed by the push rod 8, and the sliding vertical plate 7 slides laterally along the guide column 13 away from the storage box 16, and drives the first rack 14 to move synchronously, and the first rack 14 drives the transmission gear 17 to rotate clockwise, and the transmission gear 17 drives the second rack 18 to move toward the storage box 16. In this way, the second rack 18 pushes the squeezing plate 19 to slide from one side of the storage box 16 to the other side, so as to squeeze the waste falling into the storage box 16 and press the waste together, so as to avoid the plate-like waste occupying space and being scattered, affecting subsequent processing.

[0043] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
