Description

Technical Field

[0001] This invention relates to the technical field of laser cutting, and in particular to a conveying device for laser cutting and its working method. Background Technology

[0002] Laser cutting is a thermal processing technology that uses a high-energy-density laser beam to irradiate a workpiece, causing the material to melt, vaporize, or reach its ignition point rapidly. Simultaneously, a high-speed airflow removes the molten material, resulting in precise cutting. It features high precision, high speed, smooth cuts, and strong adaptability, and is widely used in the processing and manufacturing of materials such as metals, plastics, and wood. It is one of the core technologies of modern precision manufacturing.

[0003] During laser cutting, the surface of the workpiece often contains impurities such as dust, oil, and metal shavings. These impurities can cause energy scattering and reduced focusing accuracy during laser cutting, resulting in rough cut surfaces and dimensional deviations, which seriously affect the cutting quality. Traditional laser cutting conveyor devices only have a single workpiece conveying function and lack a synchronous cleaning structure. The workpiece surface needs to be pre-treated manually or by independent cleaning equipment before conveying. This not only increases process costs and operation time, but manual cleaning is also inefficient and incomplete, while independent cleaning equipment occupies extra space, making the production process cumbersome. Some conveyor devices with cleaning functions can only clean a single surface of the workpiece and cannot achieve workpiece flipping, resulting in insufficient cleaning coverage. Moreover, the cleaning components are mostly fixed structures, resulting in uneven contact with the workpiece surface and easy cleaning dead corners. Summary of the Invention

S4: After initial cleaning, the workpiece continues to move with the conveyor belt and is guided to the flipping area by the converging plate; the linkage on the surface of the conveyor belt moves synchronously with the conveyor belt, the inclined transmission block contacts the connecting bent rod, and the pressing of the connecting bent rod drives the flipping plate to rotate around the collar. The flipping plate drives the workpiece to flip, and the stop block limits the flipping plate so that the lower surface of the workpiece faces upward; the arc panel blocks the workpiece that has not entered the flipping area.

[0017] The beneficial effects of this invention are: the cleaning component can specifically remove impurities from the workpiece surface, and the flipping component can drive the workpiece to flip, so that both sides of the workpiece can be effectively cleaned.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0031] Example 1 Reference Figure 1-5 This is the first embodiment of the present invention, which provides a conveying device for laser cutting, the device comprising, The conveying mechanism 100 includes two sets of support frames 110, a rotating drum 120 rotatably mounted inside the support frame 110, a conveyor belt 130 sleeved on the surface of the rotating drum 120, a conveyor motor 140 fixed to one side of the support frame 110, a transmission component 150 for connecting the two sets of conveyor belts 130 for synchronous conveying, and a fixed housing 160 fixed between the tops of the two sets of support frames 110. The cleaning mechanism 200 includes a cleaning component 210 for cleaning the surface of the workpiece to be cut, and a flipping component 220 used in conjunction with the cleaning component 210 to flip the workpiece to improve the cleaning effect.

[0032] Among them, the cleaning component 210 can specifically remove impurities from the surface of the workpiece, and the flipping component 220 can drive the workpiece to flip, so that both sides of the workpiece can be effectively cleaned. This solves the problem that traditional conveying devices can only achieve a single conveying function, cannot clean simultaneously or clean incompletely, improves the cleanliness of the workpiece surface, and provides a guarantee for the quality of subsequent laser cutting. There is no need to set up an additional independent cleaning device, saving space and process costs.

[0033] Specifically, the transmission component 150 includes a primary pulley 151 fixed to one side of the rotating drum 120, a primary belt 152 sleeved on the surface of the primary pulley 151 and used for transmission, a secondary pulley 153 fixed on the two intermediate rotating drums 120, and a secondary belt 154 sleeved on the surface of the secondary pulley 153 and used for transmission.

[0034] Through the multi-stage transmission cooperation of primary pulley 151, primary belt 152, secondary pulley 153 and secondary belt 154, the power of the transmission motor 140 can be stably transmitted to all drums 120, ensuring that the transmission speed of the two sets of conveyor belts 130 is completely consistent, and avoiding workpiece skewing and jamming due to the speed difference of a single set of conveyor belts.

[0035] Furthermore, the cleaning component 210 includes a cleaning motor 211 fixed to one side of the fixed housing 160, a rotating rod 212 rotatably mounted inside the fixed housing 160 and whose end is fixedly connected to the output end of the cleaning motor 211, a linkage protrusion 213 fixed to the surface of the rotating rod 212, two cleaning cylinders 214 symmetrically sleeved on the surface of the rotating rod 212 for cleaning the workpiece, a linkage groove 215 opened inside the cleaning cylinder 214 and used in conjunction with the linkage protrusion 213, and a swinging component 216 that uses the cleaning motor 211 to drive the two cleaning cylinders 214 to swing back and forth.

[0036] The cleaning motor 211 drives the rotating rod 212 to rotate. Through the cooperation of the linkage protrusion 213 and the linkage groove 215, the two cleaning cylinders 214 rotate synchronously to achieve rotational cleaning of the workpiece surface. At the same time, the swinging component 216 uses the power of the cleaning motor 211 to drive the cleaning cylinders 214 to swing back and forth, so that the contact between the cleaning cylinders 214 and the workpiece surface is more comprehensive and uniform, avoiding cleaning dead corners. The two cleaning cylinders 214 are symmetrically arranged, which can clean different areas of the workpiece surface at the same time, improving cleaning efficiency.

[0037] Preferably, the swing member 216 includes two moving rings 2161 sleeved on the surface of the rotating rod 212 and used to squeeze and move the cleaning cylinder 214, a transmission plate 2162 fixed to the top of the moving rings 2161 and extending to the top of the fixed housing 160, a cam 2163 rotatably mounted on the top of the fixed housing 160 via a fixing frame and used to alternately squeeze the two transmission plates 2162, a ring plate 2164 bearing mounted on the surface of the cleaning cylinder 214, and a return spring 2165 fixed to the surface of the ring plate 2164; The return spring 2165 is used to maintain the elastic force on the cleaning cylinder 214 to improve the power of the cleaning cylinder 214 swinging back. The output end of the cleaning motor 211 is connected to the cam 2163 for transmission.

[0038] The rotating power of the cleaning motor 211 is converted into the reciprocating swing power of the cleaning cylinder 214 through the cooperation of the moving ring 2161, the transmission plate 2162 and the cam 2163, eliminating the need for an additional drive source and reducing energy consumption. The ring plate 2164 and the return spring 2165 provide a stable swing force for the cleaning cylinder 214, ensuring that the cleaning cylinder 214 quickly returns to its original position after swinging, thus ensuring the continuity and stability of the swing cleaning. The squeezing drive of the moving ring 2161 on the cleaning cylinder 214 makes the swing amplitude of the cleaning cylinder 214 controllable, avoiding workpiece collision damage due to excessive swinging, while improving the uniformity of the cleaning force and further optimizing the cleaning effect.

[0039] Furthermore, a driven bevel gear 2166 is fixedly installed on one side of the cam 2163, a driving wheel 2167 is fixedly installed at the output end of the cleaning motor 211, a linkage rod 2168 is rotatably installed on the top of the fixed housing 160, a driven wheel 2169 is fixedly installed on one side of the linkage rod 2168, the driven wheel 2169 and the driving wheel 2167 are connected by a transmission belt, and a driving bevel gear 21610 that meshes with the driven bevel gear 2166 is fixedly installed at the other end of the linkage rod 2168.

[0040] The cleaning motor 211 transmits power to the cam 2163 laterally through the cooperation of the drive wheel 2167, the transmission belt, the driven wheel 2169 and the linkage rod 2168. Then, through the meshing transmission of the drive bevel gear 21610 and the driven bevel gear 2166, the lateral power is converted into the rotational power of the cam 2163. At the same time, the rotational speed of the cam 2163 is matched with the rotational speed of the rotating rod 212 to ensure that the rotational cleaning and reciprocating oscillation of the cleaning cylinder 214 are carried out in coordination.

[0041] Furthermore, the top of the fixed housing 160 has two reserved slots for moving with the transmission plate 2162, and guide rods are fixedly installed inside the reserved slots. The surface of the transmission plate 2162 has guide holes for use with the guide rods, and the guide rods pass through the guide holes.

[0042] The reserved slot provides movement space for the transmission plate 2162. The cooperation between the guide rod and the guide hole on the surface of the transmission plate 2162 plays a precise guiding role in the movement of the transmission plate 2162, avoiding the transmission plate 2162 from deviating or jamming during the movement, and ensuring that the transmission plate 2162 drives the moving ring 2161 to move smoothly.

[0043] In use, the conveyor belt 130 moves the workpiece into the fixed housing 160. The cleaning motor 211 drives the rotating rod 212 to rotate, which drives the two cleaning cylinders 214 to rotate synchronously through the linkage protrusion 213 and the linkage groove 215. At the same time, the cleaning motor 211 drives the cam 2163 to rotate through the driving wheel 2167, the transmission belt, the driven wheel 2169, the linkage rod 2168 and the bevel gear set. The cam 2163 alternately squeezes the transmission plates 2162 on both sides, and pushes the cleaning cylinder 214 to swing back and forth through the moving ring 2161. The rotation and swing work together to thoroughly clean the impurities on the surface of the workpiece. The return spring 2165 ensures that the cleaning cylinder 214 continues to swing back.

[0044] In summary, the cleaning component 210 can specifically remove impurities from the workpiece surface, and the flipping component 220 can flip the workpiece so that both sides of the workpiece can be effectively cleaned. This solves the problem that traditional conveying devices can only achieve a single conveying function and cannot clean simultaneously or thoroughly. It improves the cleanliness of the workpiece surface, provides a guarantee for the quality of subsequent laser cutting, and eliminates the need for additional independent cleaning equipment, saving space and process costs.

[0045] Example 2 Reference Figure 6-8This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the flipping component 220 includes a converging plate 221 fixed inside the fixed housing 160 and used to connect two sets of conveyor belts 130, a collar 222 sleeved on the surface of the conveyor belt 130, a connecting bent rod 223 fixed on the surface of the collar 222, a flipping plate 224 disposed at the other end of the connecting bent rod 223 and used to flip the workpiece, a torsion spring sleeve 225 disposed between the flipping plate 224 and the connecting bent rod 223, a linkage component 226 fixed on the surface of the conveyor belt 130 and used to drive the flipping plate 224 to flip the workpiece, and an arc panel 227 fixed at the bottom of the flipping plate 224 and used to block unflipped workpieces.

[0046] Among them, the converging plate 221 can guide the workpieces on the conveyor belt 130 to the flipping area, ensuring that the workpieces accurately enter the flipping station; the cooperation of the collar 222, the connecting bent rod 223 and the flipping plate 224 can drive the workpiece to achieve the flipping action, so that the uncleaned side of the workpiece faces upward, which is convenient for the cleaning component 210 to perform a comprehensive cleaning, solving the defect of traditional cleaning devices that can only clean a single surface of the workpiece; the torsion spring sleeve 225 provides the reset power for the flipping plate 224, ensuring that it quickly returns to the initial position after flipping; the linkage component 226 realizes the synchronous linkage between the flipping action and the transmission of the conveyor belt 130, without the need for an additional drive mechanism; the arc panel 227 can block and limit the unflipped workpieces to prevent them from falling.

[0047] Specifically, the linkage 226 includes a fixed sleeve 2261 fixed to the surface of the conveyor belt 130, a protrusion 2262 fixed to the surface of the fixed sleeve 2261, a groove 2263 formed on one side of the protrusion 2262, a compression spring 2264 fixed inside the groove 2263, and an inclined transmission block 2265 fixed to the other end of the compression spring 2264 and used to drive the connecting bent rod 223 to rotate.

[0048] When the conveyor belt 130 is in motion, the inclined transmission block 2265 contacts the connecting bent rod 223. The inclined structure converts the linear power of the conveyor belt 130 into the rotational power of the connecting bent rod 223, which drives the flipping plate 224 to flip. The compression spring 2264 can ensure the transmission of power between the inclined transmission block 2265 and the connecting bent rod 223. This linkage structure does not require additional control elements, realizes the automatic triggering of the flipping action, and is synchronized with the conveyor belt drive, improving the automation level and operation continuity of the device.

[0049] Furthermore, a stop block 228 is fixedly installed on the top of the inner cavity of the fixed outer shell 160. The stop block 228 is used to limit the flipping plate 224 to flip. An abutment block 229 is fixedly installed on the side of the converging plate 221 near the flipping plate 224. A docking groove 2210 for use with the abutment block 229 is opened on one side of the flipping plate 224.

[0050] Among them, the stop block 228 can precisely limit the flipping angle of the flipping plate 224, so as to prevent the flipping plate 224 from over-flipping and causing the workpiece to fall or be damaged, and ensure that the workpiece is in a stable position to be cleaned after flipping; the abutment block 229 cooperates with the docking groove 2210. When the flipping plate 224 is reset, the abutment block 229 is embedded in the docking groove 2210 to achieve precise positioning of the flipping plate 224, ensuring smooth connection between the flipping plate 224 and the converging plate 221, and preventing the workpiece from getting stuck during the conveying process.

[0051] During use, the workpiece, after initial cleaning, continues to move along the conveyor belt 130 and is guided to the flipping area by the converging plate 221; the linkage 226 on the surface of the conveyor belt 130 moves synchronously with the conveyor belt, the inclined transmission block 2265 contacts the connecting bent rod 223, and the pressing of the connecting bent rod 223 drives the flipping plate 224 to rotate around the collar 222. The flipping plate 224 drives the workpiece to flip, and the stop block 228 limits the flipping plate 224 so that the lower surface of the workpiece faces upward; the arc plate 227 blocks the workpiece that has not entered the flipping area.

[0052] Example 3 Reference Figures 1-8 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a working method, including a conveying device for laser cutting, the method comprising the following steps: S1: Place the workpiece to be laser cut on the conveyor belt 130, ensuring that the workpiece is placed stably without obvious deviation. Start the conveyor motor 140 and the cleaning motor 211. The conveyor motor 140 drives the two sets of conveyor belts 130 to run synchronously through the transmission component 150. The cleaning motor 211 drives the cleaning component 210 and the flipping component 220 to enter the working state. S2: The conveyor belt 130 drives the workpiece to move into the fixed housing 160. The cleaning motor 211 drives the rotating rod 212 to rotate, and through the linkage protrusion 213 and linkage groove 215, it drives the two cleaning cylinders 214 to rotate synchronously. S3: At the same time, the cleaning motor 211 drives the cam 2163 to rotate through the driving wheel 2167, transmission belt, driven wheel 2169, linkage rod 2168 and bevel gear set. The cam 2163 alternately squeezes the transmission plates 2162 on both sides, and pushes the cleaning cylinder 214 to swing back and forth through the moving ring 2161. The rotation and swing work together to thoroughly clean the impurities on the surface of the workpiece. The return spring 2165 ensures that the cleaning cylinder 214 continues to swing back. S4: After initial cleaning, the workpiece continues to move with the conveyor belt 130 and is guided to the flipping area by the converging plate 221. The linkage 226 on the surface of the conveyor belt 130 moves synchronously with the conveyor belt. The inclined transmission block 2265 contacts the connecting bent rod 223 and squeezes the connecting bent rod 223 to drive the flipping plate 224 to rotate around the collar 222. The flipping plate 224 drives the workpiece to flip. The stop block 228 limits the flipping plate 224 so that the lower surface of the workpiece faces upward. The arc panel 227 blocks the workpiece that has not entered the flipping area.
