Description

Technical Field

[0001] The present invention relates to the technical field of range hood production, and particularly relates to a forming and processing device and a processing method for the oil mesh smoke hood of a range hood. Background Art

[0002] A range hood is a kitchen appliance for purifying the kitchen environment, which quickly sucks away the waste generated by stove combustion and the oil fumes generated during the cooking process and discharges them outdoors. At the same time, the oil fumes are condensed and collected to reduce pollution, purify the air, and have the functions of preventing poison and explosion. Generally, a range hood filters oil fumes through an externally installed oil mesh smoke hood. The production and processing process of the oil mesh smoke hood requires punching, flanging, and welding processing to form multiple oil grooves and holes. The smoke collecting hood inside the range hood usually needs to be drilled, so processing equipment is required. The oil mesh smoke hood has various shapes according to the types of range hoods it is installed and configured for, including flat shapes, conical three-dimensional shapes, etc. Existing range hood mesh hoods are mostly provided with a double-layer structure, with a coarse filter with large holes on the outside and a fine filter with small holes on the inside.

[0003] The oil mesh smoke hood of a range hood can be directly drilled using a laser device. The flat oil mesh smoke hood can be directly laid flat on the conveying mechanism for direct laser drilling. However, for the conical three-dimensional oil mesh smoke hood, its overall height is relatively high. Although the impact force of the laser device on the oil mesh smoke hood during operation is tiny, it will still cause slight shaking due to unstable center of gravity. The shaking frequency is tiny, but it has a greater impact on the drilling accuracy. Summary of the Invention

[0004] Object of the Invention: To provide a forming and processing device and a processing method for the oil mesh smoke hood of a range hood, thereby solving the above problems existing in the prior art.

[0005] Technical Solution: A forming and processing device for the oil mesh smoke hood of a range hood includes a frame, a laser drilling machine located on the side of the frame, and further includes a conveying mechanism, a connecting plate, a push rod, and a clamping mechanism.

[0006] The conveying mechanism is arranged above the frame and is used for conveying the oil mesh smoke hood. The oil mesh smoke hoods are sequentially placed on the conveying mechanism. The conveying mechanism is provided with conveying wheels inside the frame, and the rotation of the conveying wheels drives the conveying mechanism to work;

[0007] The connecting plate is connected to both ends of the conveying wheel through a transition bearing, so that the connecting plate and the conveying wheel work independently. A push rod is connected between the side end of the connecting plate and the side end of the frame, and the push rod pushes the connecting plate to rotate on the outer periphery of the conveying wheel;

[0008] The clamping mechanism is connected to the side end of the connecting plate. The rotation of the connecting plate drives the clamping mechanism to move synchronously. The clamping mechanism is used for the limit fixation of the oil mesh hood. After the conveying mechanism conveys the oil mesh hood to a predetermined position, the clamping mechanism adsorbs and fixes the oil mesh hood, thereby preventing the oil mesh hood from shaking and affecting the operation of the laser drilling machine.

[0009] In a further embodiment, the conveying wheel extends along the width direction of the conveying mechanism and is arranged at the conveying end of the conveying mechanism;

[0010] Limiting mechanisms are symmetrically arranged on both sides of the conveying mechanism along the width direction. The limiting mechanisms are respectively arranged above the conveying wheels and are engaged with the conveying wheels to convey the oil mesh hood; Movable limiting mechanisms are arranged at both ends of the top between the conveying mechanisms. There is a certain gap between the limiting mechanisms and the ends of the conveying mechanisms. After the planar drilling is completed, a detection device can be set to bend the oil mesh hood to observe the drilling burrs.

[0011] A detection device is arranged at the conveying end of the conveying mechanism, and the detection device takes pictures and detects the bent part of the oil mesh hood.

[0012] In a further embodiment, the limiting mechanism includes a connecting housing, a belt pulley and a synchronous belt.

[0013] The connecting housing extends upward from the side end of the frame, and the connecting plate is arranged outside the connecting housing;

[0014] The belt pulleys are distributed on the connecting housing. The connecting housing is arranged between the belt pulleys and the connecting plate. The belt pulleys are connected to the connecting housing through connecting shafts. The connecting housing provides connection support for the belt pulleys. The belt pulleys are located on the outer periphery of the conveying wheels, above the conveying wheels and close to the center of the conveying wheels;

[0015] The synchronous belt is sleeved on the belt pulleys. At least two groups of belt pulleys are provided. One of the belt pulleys is provided with a driving motor. The driving motor works synchronously with the conveying mechanism, so that the synchronous belt and the conveying mechanism are synchronously conveyed. The synchronous belt extends along the curved surface at the end of the conveying mechanism. A curved surface conveying space is formed between the synchronous belt and the conveying mechanism. Furthermore, when the oil fume mesh hood is located between the synchronous belt and the conveying mechanism, curve meshing conveyance is realized, and the oil mesh hood bends along the conveyor belt, so as to facilitate subsequent detection by the detection device. A displacement hole is arranged on the connecting housing, and one of the belt pulleys is slidably connected in the displacement hole. The up and down movement of the belt pulley changes the distance between the synchronous belt and the conveying mechanism. In the case where no conveying detection is required, the synchronous belt is far away from the conveying mechanism to avoid interference with the conveying mechanism.

[0016] In a further embodiment, the clamping mechanism includes a piston rod, a deformation block and an adsorption block.

[0017] The piston rod is connected to the inner side of the connecting plate in a structural style with the same principle as that of the syringe barrel;

[0018] The deformation block is connected to the end of the piston rod. The end of the deformation block is cylindrical and located inside the piston rod. The front end is square and provided with adsorption blocks. When the piston rod is pulled, the deformation block is extruded towards the inside of the piston rod by the internal pressure;

[0019] The adsorption blocks are symmetrically arranged at the upper and lower ends of the deformation block and have opposite magnetic poles. The adsorption blocks adsorb each other after the deformation block is extruded. The deformation block is made of rubber material. The front end of the piston rod extends outward in a trumpet shape, and the extended end fits with the end of the deformation block. The extended space is the displacement space for the deformation block to displace towards the inside of the piston rod after being extruded, so as to facilitate the extrusion and deformation of the deformation block.

[0020] In a further embodiment, the front end opening of the piston rod is in a long strip shape, and a plurality of connection ports are opened above. The connection ports extend outward in a trumpet shape. The deformation block and the adsorption block combination are respectively connected to the connection ports, increasing the adsorption range of the clamping mechanism to ensure that the oil mesh smoke hood is stably kept horizontal. The front end of the piston rod always maintains a horizontal state in the transverse direction. When the connecting plate drives the clamping mechanism to rotate as a whole, the deformation block is always flush with the outer peripheral end of the oil mesh smoke hood, so as to facilitate timely fitting with the top end of the oil mesh smoke hood.

[0021] In a further embodiment, the connecting plate is provided with an adjustment hole corresponding to the deformation block. The adjustment hole is transversely and linearly opened. The piston rod is arranged on one side of the connecting plate. The front end of the piston rod passes through the adjustment hole and is connected to the deformation block. An adjustment component corresponding to the piston rod is arranged on the other side of the connecting plate. The end of the adjustment component is connected to the front end of the piston rod. The front end of the piston rod is in a long strip shape as a whole. The adjustment component is connected to the edge closest to the piston rod, and is used to drive the deformation block to linearly displace transversely in the adjustment hole.

[0022] In a further embodiment, the adjustment component includes a telescopic rod, a pressing block, a micro driving device and a telescopic spring.

[0023] The telescopic rod is provided with pressing blocks at both ends and is connected to one side of the connecting plate through the pressing blocks to support the telescopic rod. The pressing blocks are sleeved on the telescopic rod. The top end of the telescopic rod is rotatably connected to the front end of the piston rod. The other end of the telescopic rod is connected to the micro driving device. The micro driving device drives the telescopic rod to pull the deformation block to move, and the deformation block and the piston rod as a whole displace in the adjustment hole. During the forward movement of the telescopic rod, it approaches the middle of the oil mesh smoke hood and can simultaneously realize the adsorption of the oil mesh smoke hood by the adsorption block to limit and fix the oil mesh smoke hood to prevent the oil mesh smoke hood from shaking and displacing;

[0024] A telescopic spring is sleeved on the telescopic rod and is connected to the pressing block at both ends. The telescopic spring is further deformed under the displacement of the telescopic rod, and the deformation force is combined with the power of the telescopic rod to effectively ensure the overall stable displacement of the clamping mechanism.

[0025] In a further embodiment, the adjusting assembly includes a threaded rod, a fixed block, an adjusting block, and a telescopic spring.

[0026] The threaded rod is provided with a fixed block and an adjusting block at both ends. The adjusting block is threadedly connected to the threaded rod and extends to abut against the piston rod. The threaded rod is connected to the connecting plate through the fixed block. The front end of the threaded rod is threadedly connected to the adjusting block. When the threaded rod rotates, it can directly drive the adjusting block to linearly displace along the threaded rod. The other end of the threaded rod is connected to a micro drive motor, and the micro drive motor drives the threaded rod to rotate, thereby pulling the adjusting block and the deformation block to move, finely adjusting the clamping mechanism to reduce the time difference between the adsorption time of the adsorption block and the displacement time of the deformation block, and ensuring the clamping effect.

[0027] A telescopic spring is sleeved on the threaded rod, and there is a certain gap between the telescopic spring and the threaded rod to prevent mutual interference. Both ends of the telescopic spring are respectively connected to the fixed block and the adjusting block to initially buffer the vibration generated during the rotation of the thread.

[0028] A processing method of an oil net and smoke hood forming and processing device for a range hood includes the following steps:

[0029] S1. Place the oil net and smoke hood at the front end of the conveying mechanism, and the conveying mechanism transports the oil net and smoke hood to the lower part of the laser drilling machine.

[0030] S2. Start the clamping mechanism to limit and fix both ends of the oil net and smoke hood.

[0031] S3. The laser drilling machine drills the oil net and smoke hood according to a predetermined drilling route.

[0032] S4. For a flat fine oil net and smoke hood, start the limiting mechanism, and both ends of the oil net and smoke hood are conveyed between the limiting mechanism and the conveying mechanism, and the detection device detects the holes after bending.

[0033] S5. For other types of oil net and smoke hoods, directly carry out blanking and conveying.

[0034] In a further embodiment, the detection method of the detection device is as follows:

[0035] S401. The detection device is located at the end of the conveying mechanism and faces the bending surface of the oil net and smoke hood.

[0036] S402. The detection device respectively takes pictures and scans around the oil net and smoke hood in at least two directions, and the two directions include projecting vertically towards the frame and projecting vertically towards the oil net and smoke hood.

[0037] After taking a picture in the preset shooting direction, the picture is processed and detected.

[0038] Beneficial effects: The present invention relates to an oil net and smoke hood forming and processing device and a processing method for a range hood. The oil net and smoke hood are limited and fixed by clamping mechanisms arranged on both sides of the conveying mechanism in a bidirectional manner, so as to avoid the shaking of the oil net and smoke hood from affecting the working effect of the laser drilling machine. At the end of the conveying mechanism, a limiting mechanism is arranged to bend part of the oil net and smoke hood, so as to facilitate the detection device to detect burrs on the oil net and smoke hood after drilling. The holes are more easily detected and observed after deformation. The clamping mechanism is coaxially connected to the conveying mechanism and extends above the conveying mechanism. The overall structure is compact, and the clamping mechanism can be circumferentially flipped. Compared with the existing clamping mechanism, it can effectively adapt to different types of oil net and smoke hoods. The clamping mechanism uses a piston rod to control the magnets to adsorb each other to limit and fix the oil net and smoke hood, and the adjusting assembly is used to push the clamping mechanism to move to limit and fix the middle part of the oil net and smoke hood to ensure its stability. The driving force of the adjusting assembly is also used as the power source of the clamping mechanism, effectively reducing the equipment usage and avoiding resource waste.

Detailed Embodiments

[0046] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to one of ordinary skill in the art that the present invention may be practiced without one or more of these specific details. In other instances, well-known features of the art are not described in order to avoid obscuring the present invention.

[0047] The present invention provides an oil fume machine oil net and smoke hood forming and processing device. As Figure 1 shown, a frame 1 is provided. The laser drilling machine is located on the side of the frame 1. The conveying mechanism 2 is arranged above the frame 1. The conveying mechanism 2 is used for conveying the oil net and smoke hood. The oil net and smoke hoods are sequentially placed on the conveying mechanism 2. Since the laser drilling machine has an extremely small focused light spot and a small heat affected zone during processing, the conveying mechanism 2 can adopt a chain plate conveyor or a roller conveyor. When the laser drilling machine works on the oil net and smoke hood, it does not affect the conveying mechanism 2. The conveying mechanism 2 is provided with conveying wheels 201 inside the frame 1. The conveying wheels 201 extend along the width direction of the conveying mechanism 2 and are arranged at the conveying end of the conveying mechanism 2. The rotation of the conveying wheels 201 drives the conveying mechanism 2 to work. The connecting plate 3 is connected to both ends of the conveying wheels 201 through transitional bearings, so that the connecting plate 3 and the conveying wheels 201 work independently. When conveying the oil net and smoke hood, the conveying wheels 201 rotate while the connecting plate 3 remains stationary. A push rod 4 is connected between the side end of the connecting plate 3 and the side end of the frame 1. The push rod 4 can adopt existing mechanisms such as pneumatic push rods. The push rod 4 pushes the connecting plate 3 to rotate around the outer periphery of the conveying wheels 201. The clamping mechanism 5 is connected to the side end of the connecting plate 3. The rotation of the connecting plate 3 drives the clamping mechanism 5 to move synchronously. The clamping mechanism 5 is used for limiting and fixing the oil net and smoke hood. After the conveying mechanism 2 conveys the oil net and smoke hood to a predetermined position, the clamping mechanism 5 adsorbs and fixes the oil net and smoke hood, thereby preventing the oil net and smoke hood from shaking and affecting the work of the laser drilling machine.

[0048] After the inner-layer fine-filtering oil fume net cover is punched, the roughness of its holes is detected by a detection device to facilitate subsequent deburring of the holes. However, after the existing processing equipment finishes punching, it is centrally transferred to the detection area for detection. The capillary data results detected by simply laying the oil fume net cover flat are inaccurate, and a separate device is required to bend the oil fume net cover. Thus, the entire processing process is too complex and consumes a large amount of processing and detection time. Limited-position mechanisms 6 are symmetrically arranged on both sides of the conveying mechanism 2 in the width direction. The limited-position mechanisms 6 are respectively arranged above the conveying wheels 201 and are engaged with the conveying wheels 201 to convey the oil fume net cover; movable limited-position mechanisms 6 are arranged at both ends of the top between the conveying mechanisms 2. A certain gap is provided between the limited-position mechanisms 6 and the ends of the conveying mechanisms 2. After the planar punching is completed, a detection device can be set up to bend the oil fume net cover to observe the punching burrs. A detection device is arranged at the end of the conveying of the conveying mechanism 2. The detection device uses an existing ccd vision image detector to photograph and detect the bent part of the oil fume net cover.

[0049] Such as Figure 2As shown, the limiting mechanism 6 is located above the transmission wheel 201, and is used in combination with the transmission wheel 201 to bend and deform the oil screen hood to be detected, so as to facilitate detection by the detection device. The limiting mechanism 6 is provided with a connecting shell 601, and the connecting shell 601 extends upward from the side end of the frame 1, and the connecting plate 3 is arranged outside the connecting shell 601. The pulley 602 is distributed on the connecting shell 601, and the connecting shell 601 is arranged between the pulley 602 and the connecting plate 3. The pulley 602 is connected to the connecting shell 601 through a connecting shaft. The connecting shell 601 provides a connecting support force for the pulley 602. The pulley 602 is located on the periphery of the transmission wheel 201, above the transmission wheel 201, and close to the center of the transmission wheel 201. The synchronous belt 603 is sleeved on the pulley 602, and the pulley 602 is provided with at least two groups, one of which is provided with a driving motor, and the driving motor and the transmission mechanism 2 work synchronously, so that the synchronous belt 603 and the transmission mechanism 2 are transmitted synchronously, and the synchronous belt 603 extends along the curved surface at the end of the transmission mechanism 2, and a curved transmission space is formed between the synchronous belt 603 and the transmission mechanism 2. Then, when the oil fume mesh cover is located between the synchronous belt 603 and the transmission mechanism 2, curved meshing transmission is realized, and the oil mesh fume cover is bent along the conveyor belt. Since the oil mesh fume cover with fine filtering function is made of a soft material, the holes on the surface are deformed after the conveyor belt is bent, and the burrs on the holes are prominently displayed, so that it is convenient for subsequent detection devices to detect it. When the conveyor belt is engaged and transmitted in the oil-free mesh hood, the contact with the transmission mechanism 2 will affect the operation of the transmission mechanism 2. A displacement hole 604 is provided on the connection shell 601, wherein a pulley 602 is slidably connected with the displacement hole 604. The pulley 602 is connected to the displacement hole 604 through a transmission shaft. The connection between the transmission shaft and the displacement hole 604 is a snap-on connection that can fluctuate up and down. The transmission shaft is manually turned, and the pulley 602 moves up and down to change the spacing between the synchronous belt 603 and the transmission mechanism 2. In the case where transmission detection is not required, the synchronous belt 603 is away from the transmission mechanism 2 to avoid interference with the transmission mechanism 2.

[0050] The clamping mechanism 5 limits and fixes the cone-shaped oil fume net to prevent it from shaking and affecting the operation of the laser drilling machine. The clamping mechanism 5 rotates synchronously with the connecting plate 3 as a whole, so that the clamping mechanism 5 is moved flush with the end of the oil fume net cover to facilitate its limit and fixation. The existing clamping mechanism only completes the clamping by being liftable, but the material of the oil net fume hood is relatively soft, and the adjustment accuracy of the lifting height is limited, which easily causes the surface of the oil net fume hood to be damaged by overpressure.

[0051] like Figures 3 to 4As shown, the clamping mechanism 5 is provided with a piston rod 501, and the piston rod 501 is connected to the inner side of the connecting plate 3 in a syringe-like manner. A deformation block 502 is connected to the end of the piston rod 501. The end of the deformation block 502 is cylindrical and located inside the piston rod 501, and the front end is square and provided with an adsorption block 503. When the piston rod 501 is pulled, the deformation block 502 is extruded into the piston rod 501 under internal pressure. The adsorption blocks 503 are symmetrically arranged at the upper and lower ends of the deformation block 502, and the magnetic poles are opposite. The adsorption blocks 503 adsorb each other after the deformation block 502 is extruded. The deformation block 502 is made of rubber material. The front end of the piston rod 501 extends outward in a trumpet shape, and the extended end fits the end of the deformation block 502. The extended space is the displacement space for the deformation block 502 to displace into the piston rod 501 after being extruded, so as to facilitate the extrusion and deformation of the deformation block 502. Before the piston rod 501 moves, the distance between the adsorption blocks 503 remains outside the magnetic adsorption range. After the deformation block 502 is extruded, the adsorption blocks 503 approach each other until they are within the magnetic range, and the adsorption blocks 503 automatically adsorb. The front end of the piston rod 501 is preferably made of soft rubber material. When the adsorption block 503 is extruded into the piston rod 501, it expands adaptively, and when the adsorption block 503 automatically adsorbs, it automatically contracts and fits the deformation block 502, so as to keep the inside of the piston rod 501 in a pumping state. The piston rod 501 stops pumping until the adsorption block 503 automatically adsorbs. In this embodiment, the inside of the piston rod 501 can also be directly replaced with a pull rod, and the pull rod is directly connected to the end of the deformation block 502 to pull the deformation block 502.

[0052] As Figures 2 to 5 shown, the front end opening of the piston rod 501 is in a long strip shape, and a plurality of connection ports 504 are provided above. The connection ports 504 extend outward in a trumpet shape. The combination of the deformation block 502 and the adsorption block 503 is respectively connected to the connection ports 504 to increase the adsorption range of the clamping mechanism 5 to ensure that the oil mesh hood is stably kept horizontal. The front end of the piston rod 501 always maintains a horizontal state in the transverse direction. When the connecting plate 3 drives the clamping mechanism 5 to rotate as a whole, the deformation block 502 is always flush with the outer peripheral end of the oil mesh hood, so as to facilitate timely fitting with the top of the oil mesh hood.

[0053] The connecting plate 3 only drives the entire clamping mechanism 5 to rotate. For oil mesh hoods of different sizes, it is impossible to effectively ensure that the clamping mechanism 5 is aligned with the middle part of the oil mesh hood. When the oil mesh hood is higher than the horizontal position of the deformation block 502, the connecting plate 3 rotates clockwise, driving the entire deformation block 502 to displace obliquely upward, and the deformation block 502 displaces backward. At this time, the oil mesh hood is located directly below the laser drilling. Without changing the position of the laser drilling, the deformation block 502 needs to move forward relatively to fix the middle part of the oil mesh hood. The connecting plate 3 is provided with an adjustment hole 301 corresponding to the deformation block 502. The adjustment hole 301 is opened horizontally in a straight line. The piston rod 501 is arranged on one side of the connecting plate 3. The front end of the piston rod 501 passes through the adjustment hole 301 and is connected to the deformation block 502. On the other side of the connecting plate 3, an adjustment component 7 corresponding to the piston rod 501 is provided. The end of the adjustment component 7 is connected to the front end of the piston rod 501. The front end of the piston rod 501 is integrally strip-shaped. The adjustment component 7 is connected to the edge closest to the piston rod 501, and is used to drive the deformation block 502 to linearly displace horizontally within the adjustment hole 301.

[0054] The adjustment component 7 is used to drive the deformation block 502 to displace, and the adsorption block 503 on the deformation block 502 is adsorbed by the drive of the piston rod 501. Both the piston rod 501 and the adjustment component 7 are relatively connected to the connecting plate 3. Therefore, the adjustment component 7 and the piston rod 501 can use the same driving force. After the piston rod 501 moves to a predetermined time, it engages with the adjustment component 7 and drives the adjustment component 7 to move, so as to reduce the waste of the power source. Such as Figure 5As shown in the figure, the adjusting assembly 7 is provided with a telescopic rod 701. At both ends of the telescopic rod 701, there are pressing blocks 702, which are connected to one side of the connecting plate 3 through the pressing blocks 702 to support the telescopic rod 701. The pressing blocks 702 are sleeved on the telescopic rod 701. The top of the telescopic rod 701 is rotatably connected to the front end of the piston rod 501. The other end of the telescopic rod 701 is connected to a micro driving device 703. The micro driving device 703 can be of types such as a telescopic cylinder. It drives the telescopic rod 701 to telescopically displace within the pressing block 702, and then drives the telescopic rod 701 to pull the deformation block 502 to move. The deformation block 502 and the piston rod 501 as a whole displace within the adjusting hole 301. When the deformation block 502 displaces, it simultaneously drives the front end of the piston rod 501 to synchronously displace, so that the movement at the front end is converted into the driving force. The clamping mechanism 5 is flush in the horizontal direction in the initial state. At this time, the working part of the laser drilling machine is opposite to the center of the deformation block 502 in the clamping mechanism 5. Any rotation of the clamping mechanism 5 is a backward displacement relative to the laser drilling machine. Therefore, the telescopic rod 701 always needs to push the deformation block 502 forward. During the forward movement, while approaching the middle of the oil mesh hood, it can also realize the adsorption of the adsorption block 503 to the oil mesh hood to limit and fix the oil mesh hood and prevent the oil mesh hood from shaking and displacing. A telescopic spring 704 is sleeved on the telescopic rod 701 and is respectively connected to the pressing blocks 702 at both ends. The telescopic spring 704 further deforms under the displacement of the telescopic rod 701. The deformation force is combined with the power of the telescopic rod 701 to effectively ensure the overall stable displacement of the clamping mechanism 5.

[0055] As Figure 6 shown in the figure, another technical solution of the adjusting assembly 7 is that it is provided with a threaded rod 705. At both ends of the threaded rod 705, there are fixed blocks 706 and adjusting blocks 707. The adjusting blocks 707 are threadedly connected to the threaded rod 705 and extend to abut against the piston rod 501. The threaded rod 705 is connected to the connecting plate 3 through the fixed blocks 706. The front end of the threaded rod 705 is threadedly connected to the adjusting block 707. When the threaded rod 705 rotates, it can directly drive the adjusting block 707 to linearly displace along the threaded rod 705. The other end of the threaded rod 705 is connected to a micro driving motor 708. The micro driving motor 708 drives the threaded rod 705 to rotate and then pulls the adjusting block 707 and the deformation block 502 to move. By adopting the minimum numerical value of the thread coefficient, the micro displacement of the deformation block 502 can be realized. When the difference between the deformation block 502 and the center position of the oil mesh hood is very small, micro adjustment can be carried out to reserve the gas transmission time to reduce the time difference between the adsorption time of the adsorption block 503 and the displacement time of the deformation block 502 and ensure the clamping effect. A telescopic spring 704 is sleeved on the threaded rod 705. There is a certain gap between the telescopic spring 704 and the threaded rod 705 to prevent mutual interference. The telescopic spring 704 is respectively connected to the fixed block 706 and the adjusting block 707 at both ends to initially buffer the vibration generated during the thread rotation.

[0056] In addition, the present invention provides a processing method for a forming and processing device of an oil mesh hood of a range hood, and the processing method includes the following steps:

[0057] S1. The oil mesh hoods to be processed are sequentially placed at the front end of the conveying mechanism 2. The conveying mechanism 2 is started to convey the oil mesh hoods to the lower part of the laser drilling machine, and then the conveying mechanism 2 stops.

[0058] S2. The push rod 4 pushes the connecting plate 3 to rotate, thereby driving the whole clamping mechanism 5 to rotate. The adsorption blocks 503 on the clamping mechanism 5 are flush with the top of the oil mesh hood. The clamping mechanism 5 is started by the micro driving device 703. The adjusting component 7 pushes the adsorption blocks 503 and the piston rod 501 as a whole to linearly displace, so that the adsorption blocks 503 gradually tend to the middle part of the oil mesh hood. At the same time, the telescopic rod 701 drives the piston rod 501 to pull the deformation block 502, and the adsorption blocks 503 adsorb each other to limit and fix the two ends of the oil mesh hood.

[0059] S3. The laser drilling machine drills the oil mesh hood according to different types of oil mesh hoods according to the predetermined drilling route set by the system.

[0060] S4.
