Description

Technical Field

[0001] This invention belongs to the field of CNC machine tool technology, specifically relating to an automated processing device for high-gloss cutting and precise drilling of camera metal parts. Background Technology

[0002] In the intelligent manufacturing equipment industry, CNC machine tools are the basic equipment used to manufacture industrial products, including CNC lathes, CNC milling machines, CNC grinding machines, and CNC machining centers. Their technological level directly determines a country's overall industrial strength and competitiveness. Among them, CNC milling machines include vertical CNC milling machines, horizontal CNC milling machines, and gantry CNC milling machines. The high-precision gantry CNC milling machine is a product of the deep integration of precision machining execution layer with digitalization, networking, and intelligence. Its development level is directly related to a country's core competitiveness in the high-end consumer electronics industry chain.

[0003] Existing high-precision machining centers employ an ultra-high speed spindle system of 60,000 rpm to 100,000 rpm to perform micro-cutting on the workpiece surface, and use high-precision linear guides and ball screws for servo feed on the XZ axis. Combined with a bed made of granite material with excellent shock absorption and thermal stability, and feedback devices such as grating rulers, they can achieve positioning accuracy at the micron or even sub-micron level.

[0004] In actual high-gloss machining, high-gloss machines primarily rely on negative pressure suction cups to hold the workpiece. Although ultrasonic cleaning or cleaning rollers are typically used to clean the workpiece surface before loading, the following issues still urgently need improvement: 1. Ultrasonic or cleaning roller equipment can easily encroach on the loading and unloading space, thus affecting the loading and unloading capacity of the high-gloss machine.

[0005] 2. Cleaning operations need to be performed separately by staff, making it difficult to complete the cleaning of workpieces simultaneously during the loading process. As the loading volume increases, the cleaning operation leads to a significant increase in loading time. Summary of the Invention

[0006] The purpose of this invention is to provide an automated processing device for high-gloss cutting and precise drilling of camera metal parts, which can actively clean during the loading process, avoid occupying the loading and unloading space, and not affect the loading and unloading process, thus solving the problem that the cleaning operation significantly increases the loading time.

[0007] The specific technical solution adopted by this invention is as follows: An automated processing device for high-gloss cutting and precision drilling of camera metal components includes a high-gloss machine body and a loading / unloading platform spaced apart. A loading / unloading robot is mounted on the loading / unloading platform. The loading / unloading robot includes a second vacuum suction cup for loading and unloading workpieces. The device also includes: The negative pressure suction head, negative pressure component, limit component and lifting electric cylinder are arranged vertically along the loading and unloading machine platform. The opening of the negative pressure suction head faces the loading and unloading robot and the opening is equipped with an active cleaning component. The negative pressure suction head includes a dust collection hopper and a rubber roller and a brush that are in contact with each other at the opening of the dust collection hopper; The rubber roller and brush are used to provide friction for the workpiece during the loading process of the second vacuum suction cup, so that impurities on the surface of the workpiece are removed. The negative pressure suction head generates suction under the negative pressure condition of the negative pressure component to attract impurities and dust. The limiting component is used to remove the rubber roller and brush during the process of the lifting electric cylinder lowering the negative pressure suction head, so that the rubber roller and brush reach the external cleaning station.

[0008] As an alternative, the active cleaning assembly includes a motor and a mounting ring connected in sequence laterally along the opening of the loading / unloading robot, and the mounting ring is radially welded with a support arm and an elastic cleaning head. The motor is used to provide driving force to the mounting ring, which drives the support arm and the elastic cleaning head to rotate. The elastic cleaning head intermittently scrapes the surface of the workpiece and impacts the brush, so that the brush and the rubber roller intermittently collide to form an inertial force to shake off impurities.

[0009] As an optional solution, the active cleaning assembly also includes a rotating shaft connected to the motor output and passing through the middle of the mounting ring; The mounting rings are configured in three sets and spaced apart on the rotating shaft. The elastic cleaning heads of the three sets of mounting rings alternately scrape the workpiece surface and impact the brush, causing the brush to collide intermittently with the rubber roller at different positions.

[0010] As an optional solution, the limiting component includes a slot and a block that are disposed at the opening of the ash hopper and can be inserted into each other, and a limiting frame and a positioning seat located on the top of the limiting frame are provided on the outside of the loading and unloading machine. The lifting electric cylinder is used to lower the ash collection hopper along the inside of the limiting frame, and the positioning seat is used to provide support for the rubber roller and brush when the ash collection hopper passes the limiting frame, so that the rubber roller and brush vertically detach from the ash collection hopper along the positioning seat and reach the external cleaning station.

[0011] As an optional solution, the limiting component also includes a silicone pad adhered to the edge of the card slot, the silicone pad being used to seal the gap between the card slot and the insert block; The outer side of the insert block is welded with a movable plate for supporting the rubber roller and the brush.

[0012] As an alternative, the four corners of the movable plate are bent and extended; Two corners of the movable plate are rotatably connected to the rubber roller and the brush, while the other two corners are supported on the inner wall of the ash collection hopper.

[0013] As an optional solution, the negative pressure suction head further includes: A fork-shaped bearing seat is provided at the opening of the negative pressure suction head, and the fork-shaped bearing seat is rotatably connected to the rubber roller and the brush. Mutually compatible sliders and slide rails are arranged between the ash collection hopper and the loading and unloading machine platform; A support bracket is detachably connected to the outside of the ash collection hopper, and the lifting electric cylinder rod is connected to the ash collection hopper through the support bracket.

[0014] As an alternative, the surface of the rubber roller is provided with radial grooves for scraping impurities on the surface of the workpiece, and the ends of the brush bristles are hammer-shaped to scrape off impurities adhering to the inside of the grooves.

[0015] As an optional solution, the negative pressure assembly includes an air guide pipe, an air compression tank, an air delivery pipe, and an air compressor that are connected vertically along the ash collection hopper in sequence. The air compressor is used to draw air from the air compression tank along the air delivery pipe to form a negative pressure condition with a preset pressure, so that the ash collection hopper and the air delivery pipe can generate a negative pressure airflow.

[0016] As an alternative, the air compressor tank is filled with a filter element for filtering impurities and dust in the negative pressure airflow, and the filter element is spaced apart from the air delivery pipe.

[0017] The technical effects achieved by this invention are as follows: This invention provides a CNC machine tool for intelligent manufacturing that can perform active cleaning during the loading process, avoiding encroachment on loading and unloading space, and not affecting the loading and unloading process, thus solving the problem of significantly increased loading time caused by cleaning operations.

[0018] This invention provides a CNC machine tool for intelligent manufacturing that combines active and passive cleaning. The active cleaning stage generates vibration, using inertia to shake off impurities and dust. The passive cleaning stage forcibly removes residual impurities and dust.

[0019] This invention provides a CNC machine tool for intelligent manufacturing, capable of raising and lowering a negative pressure suction head according to the production process to meet the cleaning needs of workpieces of different sizes. During the descent, the negative pressure suction head opens, exposing a portion for forced cleaning. Attached Figure Description

[0022] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0023] like Figures 1-16 As shown, an automated processing device for high-gloss cutting and precision drilling of camera metal parts is used to process camera metal parts. It includes a high-gloss machine body 1 and a loading / unloading platform 2 arranged at intervals. The loading / unloading platform 2 is equipped with a loading / unloading robot 3. It also includes a negative pressure suction head 4, a negative pressure component 6, a limit component 8 and a lifting electric cylinder 5 arranged vertically along the loading / unloading platform 2. The opening of the negative pressure suction head 4 faces the loading / unloading robot 3 and an active cleaning component 7 is provided at the opening. During operation, the operator stacks the workpieces in the loading / unloading platform 2, and the loading / unloading robot 3 picks up individual workpieces and transfers them into the high-gloss machine body 1 for high-speed milling. During the workpiece transfer process, the active cleaning component 7 scrapes away impurities and dust from the workpiece surface. At the same time, the negative pressure component 6 provides negative pressure conditions for the negative pressure suction head 4, enabling the negative pressure suction head 4 to adsorb impurities and dust, thus automatically cleaning the workpiece and avoiding taking up workpiece loading time. After the workpiece is loaded, the lifting cylinder 5 lowers the negative pressure suction head 4 until the active cleaning component 7 is separated from the negative pressure suction head 4 under the lifting action of the limiting component 8 and reaches the external cleaning station. The external cleaning station uses a fan to blow airflow or a micro water pump to spray alcohol to passively clean the active cleaning component 7, realizing intelligent cleaning during the loading and unloading process of the CNC machine tool.

[0024] Material preparation stage See attached document Figure 1 , Figure 2 and Figure 14 The loading and unloading machine 2 includes a cabinet 201. Inside the cabinet 201, a loading trough 202 and a power distribution cabinet 205 are fixed at intervals by bolt and nut kits. The operator stacks the workpieces in the material tray and then puts the material tray into the loading trough 202. The power distribution cabinet 205 is used to supply power to the loading and unloading robot 3, the lifting cylinder 5 and the active cleaning component 7. Before starting the machine, check whether there are iron filings or damage on the surfaces of the loading / unloading robot 3, the lifting cylinder 5, and the active cleaning component 7.

[0025] Specifically, the lifting electric cylinder 5 can be a NEMA17 model stepping electric cylinder.

[0026] Material feeding stage See attached document Figure 2 , Figure 4 and Figure 14 The loading and unloading robot 3 includes a first linear module 301, a second linear module 302, a third linear module 303, a lifting cylinder 304, and a second vacuum suction cup 305, which are vertically fixed to the top of the cabinet 201 by bolt and nut assembly. The second vacuum suction cup 305 is used for loading and unloading workpieces. When loading, the axis of the first linear module 301 is used as the reference. The operator establishes a spatial coordinate system and uses a preset program to make the second vacuum suction cup 305 suction the workpiece along the set path and move it. The second linear module 302 is slidably mounted on the first linear module 301 via the first slide block, the third linear module 303 is slidably mounted on the second linear module 302 via the second slide block, the lifting cylinder 304 is slidably mounted on the third linear module 303 via the third slide block, and the second vacuum suction cup 305 is mounted on the cylinder rod of the lifting cylinder 304 via a flange.

[0027] Specifically, the first linear module 301, the second linear module 302, and the third linear module 303 can be Thomson M55 series belt-driven linear modules; the lifting cylinder 304 can be CKD STS / STL series cylinders with guide rods; and the second vacuum chuck 305 can be a Ward machine tool CNC vacuum chuck, with a suction force of up to 85KG / 100cm. 3A vacuum pump and vacuum tank with a compressed air source of 0.5 MPa or higher (at a vacuum level of -0.5 MPa) and an air consumption of approximately 50 L / min.

[0028] Cleaning stage See attached document Figure 6 , Figure 7 and Figure 10 The negative pressure suction head 4 includes a dust collection hopper 401 and a rubber roller 403 and a brush 404 that are in contact with each other at the opening of the dust collection hopper 401. As the loading and unloading robot arm 3 horizontally and linearly moves the workpiece to the high-gloss machine body 1, the lifting electric cylinder 5 lifts the negative pressure suction head 4, which drives the rubber roller 403 and the brush 404 to contact and rub the workpiece to clean the impurities and dust on the surface of the workpiece, thereby realizing automated cleaning of the workpiece, avoiding the occupation of workpiece loading time, and providing a physical basis for the negative pressure suction in the high-gloss machine body 1 of the workpiece. Among them, the rubber roller 403 and the brush 404 are used to provide friction for the workpiece during the loading process of the second vacuum suction cup 305, so that impurities on the surface of the workpiece are removed. The dust collection hopper 401 generates suction under the negative pressure condition of the negative pressure component 6 to attract impurities and dust. The limiting component 8 is used to remove the rubber roller 403 and the brush 404 during the process of the lifting electric cylinder 5 lowering the dust collection hopper 401, so that the rubber roller 403 and the brush 404 reach the external cleaning station without the need for manual operation by the operator, which is conducive to improving the intelligence level of CNC machine tools.

[0029] See attached document Figure 8 , Figure 9 and Figure 10 The negative pressure suction head 4 also includes a fork-shaped bearing seat 402 welded to the opening of the negative pressure suction head 4. The ash collection hopper 401 is detachably mounted on both sides by bolt and nut kits, with a slider 405 and a support bracket 407 respectively. The cabinet 201 is fixed on one side by bolts with a slide rail 406 that is slidably connected to the slider 405. When the lifting electric cylinder 5 pushes the ash collection hopper 401, the ash collection hopper 401 is vertically lifted and lowered along the slide rail 406 via the slider 405, which makes it easy to keep the rubber roller 403 and the brush 404 parallel to the workpiece. Among them, the fork-shaped bearing seat 402 is rotatably connected to the rubber roller 403 and the brush 404 through the bearing, and the lifting electric cylinder 5 cylinder rod is connected to the ash collection hopper 401 through the bearing bracket 407.

[0030] See attached document Figure 10 The surface of the rubber roller 403 has radial grooves for scraping impurities on the workpiece surface. The groove width is set to 1mm to 3mm to accommodate impurities. The ends of the bristles of the brush 404 are hammer-shaped to scrape off the impurities attached to the inside of the grooves, so that the impurities and dust fall into the dust collection hopper 401 for easy collection by negative pressure suction.

[0031] As an alternative embodiment, the groove is W-shaped, which allows it to contact the workpiece on three sides during the extrusion process, thereby increasing the area for scraping impurities and reducing the leakage of impurities.

[0032] As an optional embodiment, the groove is provided with air leakage gaps at intervals, the width of which is no more than 0.1 mm, which can release air and reduce the stress on the surface of the rubber roller 403.

[0033] See attached document Figure 6 , Figure 7 and Figure 14 The negative pressure component 6 includes an air guide pipe 601, an air compression tank 602, an air delivery pipe 603, and an air compressor 604 that are connected vertically along the ash hopper 401. During installation, the air guide pipe 601 is connected to the ash hopper 401 and the air compression tank 602 through connectors, and the air delivery pipe 603 is connected to the air compression tank 602 and the air compressor 604 through connectors. The air compressor 604 is detachably installed inside the cabinet 201 through bolt and nut kits, and the air outlet of the air compressor 604 is connected to the factory's fresh air system through a plastic pipe. During operation, the air compressor 604 draws air from the air compression tank 602 along the air delivery pipe 603 to form a negative pressure condition with a preset pressure, so that the ash collection hopper 401 and the air delivery pipe 601 can generate a negative pressure airflow.

[0034] See attached document Figure 9 The air compressor tank 602 is filled with a filter element for filtering impurities and dust in the negative pressure airflow. The filter element can be activated carbon or pleated paper filter element. The filter element is spaced apart from the air supply pipe 603 to avoid blocking the airflow at the port of the air supply pipe 603.

[0035] See attached document Figure 10 , Figure 12 and Figure 14 The active cleaning component 7 includes a motor 701 and a mounting ring 703 connected in a transverse direction along the opening of the loading / unloading robot 3. The mounting ring 703 is radially welded with a support arm 704 and an elastic cleaning head 705. During operation, the motor 701 provides driving force to the mounting ring 703, causing the support arm 704 and the elastic cleaning head 705 to rotate. This causes the elastic cleaning head 705 to intermittently scrape the surface of the workpiece and impact the brush 404. As a result, the brush 404 and the rubber roller 403 intermittently collide to form an inertial effect, thereby shaking off impurities and achieving intelligent self-cleaning.

[0036] See attached document Figure 11 , Figure 12 and Figure 13 The active cleaning component 7 also includes a rotating shaft 702 that is connected to the output end of the motor 701 via a coupling and passes through the middle of the mounting ring 703. When the motor 701 starts, the rotating shaft 702 drives all the mounting rings 703 to rotate. Among them, the mounting rings 703 are configured in three sets and are spaced apart on the rotating shaft 702. The elastic cleaning heads 705 of the three sets of mounting rings 703 alternately scrape the workpiece surface and impact the brush 404, so that the brush 404 intermittently collides with the rubber roller 403 at different positions. At the same time, the flexible cleaning heads 705 at different positions disturb the negative pressure airflow, so that the negative pressure airflow inside the dust collection hopper 401 acts on the impurities and dust from different angles, promoting the removal of impurities and dust.

[0037] Milling stage See attached document Figure 1 , Figure 3 and Figure 14 The high-gloss machine body 1 includes a bed. Inside the bed, a servo spindle 101, a first servo rail 102, a cutter head 103, a first vacuum chuck 104, and a second servo rail 105 are arranged in order from top to bottom. A control panel 106 is connected to the outside of the bed via a rotating shaft. During installation, the first servo rail 102 and the second servo rail 105 are installed inside the bed at intervals using bolt and nut kits. The servo spindle 101 is slidably installed on the first servo rail 102 via a fourth slide, and the first vacuum chuck 104 is slidably installed on the second servo rail 105 via a fifth slide. When milling a workpiece, the second vacuum chuck 305 presses the workpiece against the first vacuum chuck 104. The first vacuum chuck 104 is evacuated to hold the workpiece in place, while the second vacuum chuck 305 releases air and leaves the machine bed to complete the clamping. Meanwhile, the operator inputs the workpiece's machining trajectory into the preset program on the control panel 106. The program controls the first servo guide rail 102 to move the servo spindle 101 and the cutter head 103, so that the servo spindle 101 and the cutter head 103 cut the workpiece along the machining trajectory at a preset speed to produce the camera metal part. The first vacuum suction cup 104 and the second vacuum suction cup 305 use the same vacuum pump.

[0038] passive cleaning stage Since impurities and dust are relatively small, they may adhere to or stick to the negative pressure suction head 4. Therefore, the present invention further provides a passive cleaning measure to passively clean the cleaning area at the opening of the negative pressure suction head 4, providing a good foundation for subsequent workpiece cleaning.

[0039] See attached document Figure 8 , Figure 9 and Figure 10The limiting component 8 includes a slot 801 and a plug 803 that are provided at the opening of the ash hopper 401 and can be inserted into each other. The cabinet 201 is provided with a limiting frame 805 and a positioning seat 806 located on the top of the limiting frame 805. During installation, the upper surface of the limiting frame 805 is welded to the bottom of the slide rail 406, and the fork-shaped bearing seat 402 is fitted around the edge of the opening of the ash hopper 401, so that the fork-shaped bearing seat 402, the rubber roller 403 and the brush 404 can be disengaged from the ash hopper 401. When the workpiece is being milled, the lifting electric cylinder 5 lowers the dust collection hopper 401 along the inside of the limiting frame 805. The positioning seat 806 is used to lift the fork-shaped bearing seat 402 when the dust collection hopper 401 passes the limiting frame 805, providing support for the rubber roller 403 and the brush 404. This causes the rubber roller 403 and the brush 404 to vertically detach from the dust collection hopper 401 along the positioning seat 806 and reach the external cleaning station. Under the action of the preset program, the miniature fan inside the cabinet 201 starts and blows airflow to the external cleaning station, forcibly blowing off the impurities and dust attached to the rubber roller 403 and the brush 404.

[0040] As an alternative embodiment, the miniature fan is replaced by a miniature liquid pump, which is equipped with an alcohol tank and an atomizing nozzle for spraying atomized alcohol onto the external cleaning station to forcefully rinse the impurities and dust adhering to the rubber roller 403 and brush 404.

[0041] See attached document Figure 10 and Figure 11 The limiting component 8 also includes a silicone pad 802 bonded to the edge of the slot 801. The silicone pad 802 is used to seal the gap between the slot 801 and the insert block 803. The fork-shaped bearing seat 402 drives the insert block 803 to rise until it is separated from the slot 801 and the silicone pad 802. The insert block 803 has a round hole 807, so that the rotating shaft 702 is rotated and installed on the insert block 803 through the bearing along the round hole 807, so that the rotating shaft 702 can rise synchronously with the rubber roller 403 and the brush 404 to achieve passive cleaning of the support arm 704 and the elastic cleaning head 705. Among them, the flexible cleaning head 705 can be made of silicone material, which can deform when squeezed and contact the workpiece with low friction to prevent obstruction of the workpiece feeding process. Meanwhile, a movable plate 804 is welded to the outside of the insert block 803. The two corners of the top of the movable plate 804 are welded to the bottom of the adjacent fork-shaped bearing seat 402, which is used to support the rubber roller 403 and the brush 404.

[0042] See attached document Figure 9 , Figure 10 and Figure 11The movable plate 804 has four bent and extended corners. Two corners of the movable plate 804 are rotatably connected to the rubber roller 403 and the brush 404, while the other two corners are supported on the inner wall of the ash hopper 401. When the rubber roller 403 and the brush 404 return to the opening of the ash hopper 401, the fork-shaped bearing seat 402 fits the edge of the opening of the ash hopper 401, while the other two corners of the movable plate 804 are supported on the inner wall of the ash hopper 401, providing stable support for the rubber roller 403 and the brush 404.

[0043] Material feeding stage See attached document Figure 2 , Figure 4 and Figure 14 The loading and unloading machine platform 2 also includes a support beam 203 and a hopper 204. The support beam 203 is fixed to the outside of the cabinet 201 by bolt and nut kit. The hopper 204 is placed on the support beam 203 and is vertically offset from the ash collection hopper 401 to prevent obstruction of the lifting and lowering of the ash collection hopper 401. When the high-gloss machine body 1 is finished, the loading and unloading robot 3 clamps and removes the camera metal parts and places them inside the unloading hopper 204.

[0044] See attached document Figure 15 and Figure 16 In this invention, a camera metal component is milled by a high-gloss machine body 1. The metal component has two to three holes and chamfered edges.

[0045] Specifically, the different pins of the control panel 106 are electrically connected to the servo spindle 101, the first servo guide rail 102, the first vacuum chuck 104, the second servo guide rail 105, the power distribution cabinet 205, the first linear module 301, the second linear module 302, the third linear module 303, the lifting cylinder 304, the second vacuum chuck 305, the lifting electric cylinder 5, the air compressor tank 602, the air compressor 604, and the motor 701.

[0046] The working principle of this invention is as follows: During operation, the operator stacks the workpieces in the material tray and then puts the material tray into the loading trough 202 to complete the material preparation.

[0047] During loading, the first linear module 301 is used as the reference axis. The operator establishes a spatial coordinate system and uses a preset program to make the second vacuum suction cup 305 clamp the workpiece along the set path and transfer it to the high-gloss machine body 1.

[0048] As the loading and unloading robot arm 3 horizontally and linearly moves the workpiece to the high-gloss machine body 1, the lifting electric cylinder 5 raises the negative pressure suction head 4, driving the rubber roller 403 and brush 404 to contact and rub the workpiece to clean impurities and dust on the workpiece surface. The air compressor 604 is used to draw air from the air compression tank 602 along the air supply pipe 603 to form a negative pressure condition with a preset pressure, so that the dust collection hopper 401 and the air guide pipe 601 generate negative pressure airflow to attract impurities and dust.

[0049] At the same time, the motor 701 provides driving force to the mounting ring 703, which drives the support arm 704 and the elastic cleaning head 705 to rotate, so that the elastic cleaning head 705 intermittently scrapes the surface of the workpiece and impacts the brush 404. Thus, the brush 404 and the rubber roller 403 intermittently collide to form an inertial effect, so as to throw off impurities.

[0050] The flexible cleaning heads 705 at different positions disturb the negative pressure airflow, causing the negative pressure airflow inside the dust collection hopper 401 to act on impurities and dust from different angles.

[0051] When milling a workpiece, the second vacuum chuck 305 presses the workpiece against the first vacuum chuck 104. The first vacuum chuck 104 is evacuated to hold the workpiece in place, while the second vacuum chuck 305 releases air and leaves the machine bed to complete the clamping. Furthermore, the operator can input the machining trajectory of the workpiece into the preset program on the control panel 106. The program controls the first servo guide rail 102 to move the servo spindle 101 and the cutter head 103, so that the servo spindle 101 and the cutter head 103 can cut the workpiece along the machining trajectory at a preset speed to produce the camera metal part.

[0052] Secondly, the lifting electric cylinder 5 lowers the dust collection hopper 401 along the inside of the limiting frame 805.
