Description

Technical Field

[0001] The present application relates to the technical field of laser drilling and cutting, and particularly relates to a laser drilling and cutting device and method for processing a metal shell of a lamp. Background Art

[0002] Laser drilling and cutting is a technology that uses a high-power density laser beam to precisely process materials. Its working principle is to irradiate the material with a laser beam, causing it to quickly melt, vaporize, or reach the ignition point. At the same time, molten material is blown away by a high-speed air flow coaxial with the beam, thereby achieving drilling and cutting. Laser drilling and cutting has the advantages of high precision, high efficiency, and applicability to a variety of materials, and is widely used in many fields such as automobile manufacturing, aerospace, medical devices, and electronic manufacturing. During the manufacturing process of lamps, metal shells are used as lamp shades or protective casings for lamps. When processing the lamp shells, in order to facilitate the installation and wiring of the lamps and for aesthetics, the lamp shells are processed by laser drilling and cutting.

[0003] Currently, when drilling and cutting on the surface of lamp shells, the formed lamp shells are placed on the processing table, and then laser drilling and cutting are performed. However, when the lamp shells are processed by laser now, it is necessary to manually fix the lamp shells to the workbench under the laser equipment by fixtures and then perform laser drilling and cutting. However, due to the large demand for processing lamp shells, through repeated loading and unloading for laser processing, not only is the manual workload large, but also the production efficiency is limited. Summary of the Invention

[0018] A first motor is bolted to the outer wall of the feeding base at one end relative to the left - right threaded rod. The output end of the first motor penetrates through the feeding base and is fixedly connected to the relative end of the left - right threaded rod.

[0019] A sliding rod is fixedly connected to the inner side of the feeding base close to the left - right threaded rod. The sliding rod penetrates through and is slidably connected to the moving plate.

[0020] Preferably, the fixing member includes a fixing base, and a guiding groove is formed at the top of the fixing base.

[0021] A control box is fixedly connected to the center position of the inner groove of the guiding groove, and an electric telescopic abutting rod is bolted to the outside of the control box.

[0022] Preferably, an anti - slip abutting strip is fixedly connected to the end of the electric telescopic abutting rod away from the control box.

[0029] Preferably, the conveying rubber plate is made of a tough colloid, and a movable chain is fixedly connected between every two conveying rubber plates.

[0030] A processing method of a laser drilling and cutting device for processing a lamp metal shell is applied to a laser drilling and cutting device for processing a lamp metal shell. The processing steps are as follows:

[0031] A1. First, place the formed lamp metal shell on the conveyor belt at the top of the loading seat. Then, adjust the two moving plates to move towards each other, so that the two guide straight plates approach each other, limit both sides of the lamp metal shell, and make the lamp metal shell move linearly towards the base. At the same time, when the lamp metal shell is placed on the conveyor belt manually or mechanically, the guide inclined plate can accurately guide the lamp metal shell into the space between the two guide straight plates through the inclination of the guide inclined plate, and the lamp metal shell moves towards the base through the conveyor belt.

[0032] A2. The conveyor belt and the conveying rubber plate start and stop conveying synchronously. The second motor drives the corresponding transmission rod and transmission shaft to rotate. At this time, the conveyor belt drives a plurality of transmission wheels to rotate synchronously through meshing. At this time, the transmission wheels make a plurality of transmission rods and transmission shafts rotate synchronously. The transmission shaft then drives the conveying rubber plate to roll and convey through meshing. The main synchronous wheel fixed to the outside of the transmission rod on the base close to the loading seat drives the driven synchronous wheel and its transmission rod to rotate synchronously through the conveyor belt. At this time, the driven synchronous wheel drives the transmission rod and its corresponding transmission rod to rotate, and this transmission rod can drive the conveyor belt on the loading seat and the conveying rubber plate to roll and convey the lamp metal shell synchronously.

[0033] A3. The metal housing of the lamp is conveyed from the loading seat to the guide plate by a conveyor belt. Subsequently, the metal housing of the lamp slides down the inclined surface of the inclined guide plate onto the conveying rubber plate of the base, and the metal housing of the lamp covers a fixing part. Then, the fixing part squeezes against the metal housing of the lamp from the inside out, thereby fixing the metal housing of the lamp on the conveying rubber plate. After that, the conveying rubber plate continues to convey the fixed metal housing of the lamp to the position below the laser head. At this time, the laser head punches or cuts the surface of the metal housing of the lamp. After the punching and cutting of the metal housing of the lamp are completed, the conveying rubber plate continues to convey the metal housing of the lamp forward. Subsequently, when the conveying rubber plate drives the metal housing of the lamp to move to the state where the inner groove of the base faces downward, at this time, the fixing part resets to release the limit, and at this time, the metal housing of the lamp can fall by gravity to complete the blanking.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] 1. By setting a loading seat and a base, and arranging a conveying rubber plate on the base to form a continuous processing platform, through the processing method of continuous feeding and automatic blanking, the process of laser punching and cutting of the lamp housing is made more efficient, and there is no need for manual repeated loading and unloading, reducing the workload of manual labor.

[0036] 2. A fixing part is arranged on the conveying rubber plate. When the lamp housing enters the conveying rubber plate on the base from the loading seat, at this time, the fixing part expands and fixes on the inner side of the lamp housing, thereby realizing the processing positioning and fixing of the lamp housing. Compared with direct conveying and processing, the laser punching and cutting position of the lamp is more accurate, and the processing process is more stable.

[0037] 3. By arranging a guide inclined plate and a guide straight plate on the loading seat, when the lamp housing is loaded, the first positioning is carried out, so that the lamp housing can be accurately and stably conveyed onto the conveying rubber plate, and can be accurately conveyed to the outside of the fixing part, and then fixed and positioned by the fixing part, thereby making the process of loading and processing the lamp housing more accurate and stable.

[0038] 4. The conveying rubber plate and the conveyor belt in the base and the loading seat are driven by transmission wheels, transmission belts, main synchronous wheels and auxiliary synchronous wheels, so that the conveyor belt and the conveying rubber plate can be started and stopped synchronously for conveying. Thus, the metal housing of the lamp can be accurately conveyed to the outside of the fixing part for fixing and then processed. This not only makes the loading and unloading process of the laser processing device more continuous, but also makes the process of conveying the metal housing of the lamp more accurate and efficient.

Detailed implementation manners

[0049] The technical solutions of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0052] In this embodiment, with reference to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 , both the base 1 and the feeding base 2 are provided with grooves at the top, and a blanking inclined plate 102 is fixedly connected inside the groove of the base 1. The base 1 is fixedly connected with a receiving box 103. Transmission shafts 3 are rotatably connected inside the grooves of both the base 1 and the feeding base 2. Meshing teeth are provided on the outer side of the transmission shaft 3. A conveying rubber plate 301 and a conveyor belt 302 are respectively sleeved on the outer sides of the transmission shafts 3 of the base 1 and the feeding base 2. Meshing teeth are provided on the outer side of the transmission shaft 3. Meshing teeth are provided on the surfaces of the conveying rubber plate 301 and the conveyor belt 302 close to the corresponding transmission shaft 3. The conveying rubber plate 301 and the conveyor belt 302 are meshed and connected to the corresponding transmission shaft 3 through the meshing teeth. The conveying rubber plate 301 is made of a rubber with toughness. An activity chain 310 is fixedly connected between the conveying rubber plates 301;

[0053] Furthermore, a plurality of transmission shafts 3 are provided on the inner sides of the grooves of the base 1 and the feeding base 2. A transmission rod 303 is fixedly connected to the same end of the plurality of transmission shafts 3 on the base 1. A motor bracket 308 is fixedly connected to the side wall position of the base 1 far from the feeding base 2 and opposite to the transmission shaft 3 and the transmission rod 303. A second motor 309 is fixedly connected to the outer wall on the outer side of the motor bracket 308. The output end of the second motor 309 penetrates through the motor bracket 308 and is connected to the corresponding transmission rod 303. A transmission wheel 304 is fixedly sleeved on the outer side of the transmission rod 303. A transmission belt 305 is meshed on the outer sides of the plurality of transmission wheels 304. Here, the transmission rod 303 installed on the base 1 penetrates through and is rotatably connected to its opposite side wall. The transmission rod 303 on the transmission shaft 3 rotatably installed in the groove of the feeding base 2 penetrates through the side wall of the feeding base 2 in a direction opposite to the penetration direction of the base 1 and the transmission rod 303. The transmission rod 303 and the transmission shaft 3 on the feeding base 2 are also driven through the transmission wheel 304 and the transmission belt 305;

[0054] Furthermore, a fixing member 4 is fixedly connected to the surface of the conveying rubber plate 301. The fixing member 4 includes a fixing base 401. A guiding groove 402 is opened at the top of the fixing base 401. A control box 403 is fixedly connected to the central position of the groove body of the guiding groove 402. Electric telescopic abutting rods 404 are fixedly connected to the four side walls of the control box 403. The other ends of the electric telescopic abutting rods 404 are fixedly connected with anti-slip abutting strips 405;

[0055] Based on the above structure and the connection relationship of the above structure, for the metal housing of the lamp (hereinafter referred to as the housing), after the housing is formed, further laser drilling and cutting processing is required. The housing is placed on the feeding seat 2 and conveyed to the conveying rubber plate 301 of the base 1 through the feeding seat 2. At this time, the control box 403 in the top guide groove 402 of the fixed seat 401 controls the electric telescopic push rod 404 to extend. Subsequently, the electric telescopic push rod 404 drives the anti-slip strip 405 to move in the direction from the inside to the outside of the housing. Then, the anti-slip strip 405 is pushed against the inside of the housing. At this time, the housing is fixed by the four electric telescopic push rods 404 and the anti-slip strips 405, and at the same time, the housing is extruded outward to be centered and positioned, so that the laser drilling and cutting position of the housing is positioned. Then, the second motor 309 drives the corresponding transmission rod 303 to rotate. At this time, the transmission rod 303 uses the transmission wheel 304 and the transmission belt 305 to make multiple transmission rods 303 and the transmission shaft 3 rotate synchronously. At this time, the transmission shaft 3 drives the conveying rubber plate 301 to move in the direction of the receiving box 103 through the meshing drive method;

[0056] When the processing is completed, the conveying rubber plate 301 continues to drive the housing to convey, and then moves to the position of the inner groove of the groove body of the base 1. Immediately, the electric telescopic push rod 404 contracts and resets. At this time, the housing will fall onto the slope surface of the blanking inclined plate 102. The surface of the blanking inclined plate 102 is provided with soft sponge. Then, the housing rolls to the inside of the receiving box 103 through the slope surface, realizing rapid blanking. Subsequently, by circulating this processing process, an efficient and stable processing flow can be achieved.

[0057] Embodiment 2:

[0058] In this embodiment, referring to Figure 1 、 Figure 2 、 Figure 4 and Figure 8 The feeding seat 2 includes a conveyor belt 302. One end of the feeding seat 2 close to the base 1 is obliquely and fixedly connected with a guide plate 204. One of the transmission rods 303 of the base 1 close to the feeding seat 2 is fixedly connected with a main synchronous wheel 306. One transmission shaft 3 of the feeding seat 2 corresponding to the main synchronous wheel 306 also has a transmission rod 303 passing through the corresponding side wall of the feeding seat 2. A sub-synchronous wheel 307 is arranged outside the transmission rod 303. The main synchronous wheel 306 and the sub-synchronous wheel 307 are meshed and sleeved with a transmission belt 305 on the outside;

[0059] Under the conditions of the above structure and the connection relationship of the above structure, the secondary synchronous pulley 307 and the primary synchronous pulley 306 are synchronously driven by the transmission belt 305. When the conveyor rubber plate 301 is driven by the second motor 309 to drive the corresponding transmission rod 303 and the transmission shaft 3, the transmission rod 303 realizes the rolling conveyance of the conveyor rubber plate 301 through the transmission wheel 304 and the transmission belt 305. At this time, the conveyor belt 302 is synchronously driven by the secondary synchronous pulley 307, the primary synchronous pulley 306 and the transmission belt 305, so that the conveyor belt 302 can start and stop simultaneously with the conveyor rubber plate 301, ensuring that the outer shell can be conveyed and fixed more precisely, and then processed. It realizes that one second motor 309 can drive the conveyor rubber plate 301 and the conveyor belt 302 to convey synchronously, which not only reduces costs, but also the synchronous start and stop can make the outer shell be conveyed at a uniform and accurate conveying speed, ensuring the accurate conveying positioning and fixed position of the outer shell during laser processing.

[0060] Embodiment 3:

[0061] In this embodiment, referring to Figure 7 , at the top position of one end of the base 1 close to the laser head 5, a linear guide rail 501 is bolted. The linear guide rail 501 penetrates and is slidably installed with a linear motor 502. The top of the linear motor 502 is bolted with a movable frame 503. Inside the top of the movable frame 503, a pneumatic telescopic rod 506 is slidably installed. The bottom end of the pneumatic telescopic rod 506 is bolted with a fixed disk 507. The bottom of the fixed disk 507 is rotatably installed with an electric turntable seat 508. The laser head 5 is rotatably installed inside the electric turntable seat 508. On the relative outer wall of the electric turntable seat 508 at the relative rotation position with respect to the laser head 5, a third motor 509 is bolted. The output end of the third motor 509 penetrates the side wall of the electric turntable seat 508 and is fixedly connected to the rotating shaft of the laser head 5. The top end of the pneumatic telescopic rod 506 is bolted with a pneumatic slider 505. On the inner side wall of the top of the movable frame 503, a pneumatic guide rail 504 is installed. The pneumatic slider 505 is slidably installed on the pneumatic guide rail 504;

[0062] Under the conditions of the above structure and the connection relationship of the above structure, when the conveyor rubber plate 301 drives the outer shell to be conveyed below the movable frame 503, the movable frame 503 is centered at the middle position of the linear guide rail 501 by the linear motor 502 at this time. Subsequently, the linear motor 502 drives the movable frame 503 to move on the outside of the linear guide rail 501, and at the same time, the laser head 5 can be driven to move in the X / Y axis directions through the pneumatic guide rail 504 and the pneumatic slider 505. Then, the laser head 5 adjusts its height position through the pneumatic telescopic rod 506. Then, the laser head 5 is driven by the third motor 509, so that the laser head 5 can adjust the laser drilling and cutting angle. Then, the laser head 5 is driven by the electric turntable seat 508 to rotate at the bottom of the fixed disk 507, and the direction of laser processing can be adjusted. Subsequently, the outer shell can be drilled and cut.

[0063] Example 4:

[0064] In this embodiment, referring to Figure 1 , Figure 2 and Figure 4 , at the bottom of one end of the feeding seat 2 far from the base 1, two vertical plates are fixedly connected. A left - right threaded rod 205 is rotatably connected between the two vertical plates. The two ends of the left - right threaded rod 205 penetrate and are threadedly connected with moving plates 201. On the side of the top of the moving plate 201 opposite to the base 1, a feeding inclined plate 202 is fixedly connected. The other end of the feeding inclined plate 202 is fixedly connected with a feeding straight plate 203. On the outer side wall of one end of the vertical plate relative to the left - right threaded rod 205, a first motor 206 is bolt - fixedly connected. The output end of the first motor 206 penetrates the vertical plate and is connected to the corresponding end of the left - right threaded rod 205. A sliding rod 207 is fixedly connected between the two vertical plates. The sliding rod 207 penetrates and is slidably connected with the moving plate 201;

[0065] Based on the above structure and the connection relationship of the above structure, first, adjust the distance between the feeding inclined plate 202 and the feeding straight plate 203 according to the type of the produced shell. First, start the first motor 206 to drive the left - right threaded rod 205 to rotate. The left - right threaded rod 205 and the sliding rod 207 cooperate to make the two moving plates 201 move synchronously towards each other. The moving plate 201 can drive the feeding inclined plate 202 and the feeding straight plate 203 to adjust to the corresponding spacing. Then, manually place the formed shell on the conveyor belt 302 on the feeding seat 2. Subsequently, the main synchronous pulley 306 of the transmission rod 303 and the transmission belt 305 drive the driven synchronous pulley 307 to rotate. At this time, the transmission shaft 3 inside the conveyor belt 302 can be driven to rotate. Immediately, the conveyor belt 302 can drive the shell to move towards the base 1. At this time, the shell closest to the base 1 slides down to the conveying rubber plate 301 along the inclined guide plate 204 due to the inclined setting of the guide plate 204, and can be fixed by the fixing member 4, and then laser drilling and cutting are carried out;

[0066] The feeding inclined plate 202 can facilitate manual or mechanical placement of the shell on the conveyor belt 302. Along with the inclined and narrowing inclined plate, the shell can accurately and smoothly enter between the two feeding straight plates 203. Subsequently, through the feeding straight plate 203, the shell can be more stable during the conveying process on the conveyor belt 302, and the shell can be more accurately conveyed onto the conveying rubber plate 301. The feeding inclined plate 202 and the feeding straight plate 203 move synchronously through the moving plate 201 and the left - right threaded rod 205, thereby facilitating the guiding and conveying of shells of different specifications.

[0067] Workflow of the present invention: First, adjust the distance between the material guiding inclined plate 202 and the material guiding straight plate 203 according to the types of the produced outer shells. First, start the first motor 206 to drive the forward and reverse threaded rod 205 to rotate. The forward and reverse threaded rod 205 cooperates with the slide rod 207, so that the two moving plates 201 move synchronously towards each other. The moving plate 201 can drive the material guiding inclined plate 202 and the material guiding straight plate 203 to adjust to the corresponding spacing. Then, manually place the formed outer shell on the conveyor belt 302 on the feeding seat 2. Subsequently, the main synchronous pulley 306 of the transmission rod 303 and the transmission belt 305 drive the secondary synchronous pulley 307 to rotate. At this time, the transmission shaft 3 inside the conveyor belt 302 can be driven to rotate. Immediately, the conveyor belt 302 drives the outer shell to move towards the base 1. At this time, the outer shell closest to the base 1 slides down along the material guiding plate 204 onto the conveying rubber plate 301 due to the inclined setting of the material guiding plate 204. At this time, the control box 403 in the guiding groove 402 at the top of the fixed seat 401 controls the electric telescopic push rod 404 to extend. Subsequently, the electric telescopic push rod 404 drives the anti-slip strip 405 to move in the direction from the inside to the outside of the outer shell. Then, the anti-slip strip 405 is pushed against the inside of the outer shell. At this time, the outer shell is fixed by the four electric telescopic push rods 404 and the anti-slip strips 405. At the same time, the outer shell is extruded outwards and centered, so that the laser drilling and cutting position of the outer shell is positioned. Then, the second motor 309 drives the corresponding transmission rod 303 to rotate. At this time, the transmission rod 303 uses the transmission wheel 304 and the transmission belt 305 to make multiple transmission rods 303 and the transmission shaft 3 rotate synchronously. At this time, the transmission shaft 3 drives the conveying rubber plate 301 to move in the direction of the receiving box 103 in a meshing driving manner. When the conveying rubber plate 301 drives the outer shell to be below the movable frame 503, the movable frame 503 is centered at the middle position of the linear guide rail 501 by the linear motor 502 at this time. Subsequently, the linear motor 502 drives the movable frame 503 to move on the outside of the linear guide rail 501. At the same time, the pneumatic guide rail 504 and the pneumatic slider 505 can drive the laser head 5 to move in the X / Y axis directions. Then, the laser head 5 adjusts its height position through the pneumatic telescopic rod 506. Then, the laser head 5 is driven by the third motor 509, so that the laser head 5 can adjust the laser drilling and cutting angle. Then, the laser head 5 is rotated by the electric rotary table seat 508 at the bottom of the fixed disk 507, so as to adjust the laser processing direction. Subsequently, the outer shell can be drilled and cut. After the processing is completed, the conveying rubber plate 301 continues to drive the outer shell to be conveyed. Then, when it is inside the groove opened on the base 1, immediately, the electric telescopic push rod 404 contracts and resets. At this time, the outer shell will fall onto the slope of the discharging inclined plate 102. The surface of the discharging inclined plate 102 is provided with soft sponge. Subsequently, the outer shell rolls to the inside of the receiving box 103 through the slope, realizing rapid discharging. Subsequently, by circulating this processing process, an efficient and stable processing flow can be realized.

[0068] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.

First, the formed metal shell of the lamp is placed on the conveyor belt (302) on the top of the loading seat (2), and then the two movable plates (201) are adjusted to move toward each other so that the two guide straight plates (203) are close to each other, and the two sides of the metal shell of the lamp are limited so that the metal shell of the lamp moves in a straight line toward the base (1). At the same time, when the metal shell of the lamp is placed on the conveyor belt (302) manually or mechanically, the guide inclined plate (202) can be inclined to guide the metal shell of the lamp to accurately enter between the two guide straight plates (203), and the metal shell of the lamp moves toward the base (1) through the conveyor belt (302); A2, the conveyor belt (302) and the conveying rubber plate (301) start and stop conveying synchronously, and the second motor (309) drives the corresponding transmission rod (303) and the transmission shaft (3) to rotate. At this time, the transmission belt (305) drives multiple transmission wheels (304) to rotate synchronously through meshing. At this time, the transmission wheel (304) causes several transmission rods (303) and the transmission shaft (3) to rotate synchronously, and the transmission shaft (3) then meshes and drives the conveying rubber plate (301) to roll and convey, and the conveying rubber plate (301) near the conveying belt (305) is driven by the transmission belt (305) to rotate synchronously. The main synchronous wheel (306) fixed on the outer side of the transmission rod (303) on the base (1) of the loading seat (2) drives the auxiliary synchronous wheel (307) and its transmission rod (303) to rotate synchronously through the transmission belt (305). At this time, the auxiliary synchronous wheel (307) drives the transmission rod (303) and its corresponding transmission rod (303) to rotate, and the transmission rod (303) can drive the conveyor belt (302) and the conveying rubber plate (301) on the loading seat (2) to synchronously roll and convey the metal shell of the lamp; A3. The metal shell of the lamp is transported from the loading seat (2) to the guide plate (204) by the conveyor belt (302), and then the metal shell of the lamp slides down the inclined surface of the guide plate (204) to the conveying rubber plate (301) of the base (1), and the metal shell of the lamp covers a fixing member (4), and then the fixing member (4) presses against the metal shell of the lamp from the inside to the outside, thereby fixing the metal shell of the lamp on the conveying rubber plate (301), and then the conveying rubber plate (301) The fixed metal shell of the lamp is continuously conveyed to the position below the laser head (5), and the laser head (5) punches or cuts the surface of the metal shell of the lamp. After the punching and cutting of the metal shell of the lamp are completed, the conveying rubber plate (301) continues to convey the metal shell of the lamp forward. Then, when the conveying rubber plate (301) drives the metal shell of the lamp to move to a state where the inner groove of the base (1) faces downward, the fixing part (4) is reset to release the limit, and the metal shell of the lamp can be unloaded by falling by gravity.
