Description

[0001] The present invention relates to the field of PCB processing equipment, and in particular to a patch processing device and method suitable for PCB raw material production. Background Art

[0002] With the continuous development of electronic products and the increasing demand for integration, PCB, as the core basic component of electronic products, plays a vital role in various electronic devices. The production process of PCB includes multiple steps, among which patch processing is one of the key links. Traditional PCB raw material patch processing equipment usually relies on a combination of manual operation and mechanical means, such as manual loading, manual grinding, manual cleaning and manual unloading.

[0015] A method for using a patch processing device suitable for PCB raw material production includes the following steps: Step 1: Start the conveyor belt to transport the PCB raw materials on the upper surface of the conveyor belt. At this time, the clamping assembly located outside the electric slider works, and the double-sided rack is driven to move along the inner wall of the fixed column by starting the first cylinder. During the movement of the double-sided rack, the two driving gears are driven to rotate, and the two clamping plates are further driven to rotate, so that the rubber clamping plate at the bottom of the clamping plate contacts the outer surface of the PCB raw material and clamps it; Step 2: Start the electric turntable to drive the electric guide rail to rotate 90 degrees, move the cut PCB raw material to the grinding assembly, and use the grinding assembly to grind the PCB raw material; Step 3: During the trimming process, the eccentric wheel is driven to rotate by starting the dual-axis motor. Since the eccentric wheel and the connecting plate are in contact with each other, the connecting plate moves up and down with the rotation of the eccentric wheel, thereby driving the spring to move synchronously. When the movable rod moves upward, it drives the rubber piston to move upward along the inner wall of the connecting cylinder. At this time, the outside air enters the interior of the connecting cylinder through the air inlet pipe. When the rubber piston moves downward, the rubber piston injects the air inside the connecting cylinder into the jet pipe through the connecting pipe, and sprays it on the outer surface of the grinding wheel through the jet pipe, so as to automatically clean the debris generated on the outer surface of the grinding wheel. Step 4: After the trimming is completed, the electric turntable is started again to drive the electric guide rail to rotate 90 degrees, and the PCB raw material after the trimming is completed is moved to the cleaning component. At this time, the second motor is started to drive the connecting gear to rotate, so that the connecting frame reciprocates left and right along the inner wall of the limit groove, so as to drive the fixed plate to move synchronously, and the scraper is used to remove the chips of the polished PCB raw material; Step 5. After cleaning, move the PCB raw material to the top of the placement rack, the clamping assembly finishes working, and starts the electric telescopic rod outside the electric slider to place the PCB raw material inside the placement rack to complete automatic unloading.

[0016] The present invention provides a patch processing device and method suitable for PCB raw material production, which has the following beneficial effects: 1. Compared with the prior art, the present invention significantly improves production efficiency by integrating automatic feeding, automatic grinding, automatic cleaning and automatic unloading functions, reduces manual operation and manual intervention, avoids time waste and unnecessary labor intensity in manual handling, loading and unloading and grinding, and makes the entire production process smoother and more stable. The automatic grinding function ensures the edge trimming accuracy of each PCB raw material, and the grinding quality is more uniform and stable, avoiding errors and quality fluctuations in manual operation. The automatic cleaning system efficiently cleans the waste and residues generated during the processing process, ensuring the good operation of the equipment and the cleanliness of the production environment, reducing the dependence on manual cleaning, and also reducing the probability of equipment failure and subsequent maintenance costs.

[0017] 2. The present invention can effectively clamp and fix PCB raw materials by adding electric sliders, electric guide rails, connecting frames, clamping plates, driving gears, double-sided racks and other structures that cooperate with each other, so that the equipment can automatically adjust according to different sizes and thicknesses of the plates, with stronger adaptability, thereby reducing manual intervention and improving the automation and flexibility of the production line.

[0021] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Please see attached Figure 1 - Attachment Figure 8 The embodiment of the present invention provides a patch processing device and method suitable for PCB raw material production, including an electric turntable 501, a first mounting frame 3, a second mounting frame 4 and a placement frame 2. An electric guide rail 504 is installed on the top of the electric turntable 501, an electric slider 503 is installed on the outside of the electric guide rail 504, a connecting frame 505 is fixedly connected to the outside of the electric slider 503, two fixed columns 502 are fixedly connected to the outside of the connecting frame 505, a first cylinder 509 is fixedly connected to the outside of the fixed column 502, a double-sided rack 508 is fixedly connected to the output end of the first cylinder 509, two driving gears 507 are movably connected to the inside of the fixed column 502 through a bearing, a clamping plate 506 is fixedly connected to the outside of the driving gear 507, the outsides of the two driving gears 507 are meshed and connected with the outside of the double-sided rack 508, and an electric telescopic rod is installed on the outside of the connecting frame 505. A cleaning component is installed on the top of the first mounting frame 3.

[0023] Specifically, after the equipment is started, the electric turntable 501 starts to rotate, and the PCB raw material is placed on the placement rack 2. At this time, the electric slider 503 slides along the electric guide rail 504, driving the connecting rack 505 to move to the desired position.

[0024] Clamping operation: Start the first cylinder 509, which pushes the double-sided rack 508 to slide along the inner wall of the fixed column 502. The double-sided rack 508 drives the driving gear 507 to rotate and clamps the PCB material through the clamping plate 506. The rubber clamping plate is in close contact with the surface of the PCB material, effectively preventing the plate from moving or deflecting.

[0025] Please see attached Figure 1 and attached Figure 4 The cleaning component includes a rack plate 803, which is fixedly connected to the top of the first mounting frame 3. A limiting groove 804 is provided on the outer side of the rack plate 803. A connecting frame 802 is slidably connected inside the limiting groove 804. A second motor 801 is fixedly connected to the outer side of the connecting frame 802. A connecting gear 805 is fixedly connected to the output end of the second motor 801. Two fixing plates 806 are fixedly connected to the outer side of the connecting frame 802.

[0026] Specifically, the limiting groove 804 is used to limit the movement trajectory of the connecting frame 802 to ensure the stability and accuracy of its movement. The design of the inner wall of the limiting groove 804 allows the connecting frame 802 to slide therein and limit its displacement range through mechanical cooperation, thereby ensuring the accurate movement of the connecting frame 802.

[0027] The second motor 801 is the power source of the driving system, and its function is to provide rotational power. The second motor 801 is fixedly connected to the outer side of the connecting frame 802, and drives the connecting gear 805 to rotate through the output end. The start-up and operation of the motor can drive the entire device to work, ensuring the continuous progress of the chip removal process.

[0028] The fixed plate 806 is a component fixedly connected to the connecting frame 802. Through the reciprocating motion of the connecting frame 802, the fixed plate 806 can move synchronously and move along the specified track. A scraper 807 is arranged on the outer side of the fixed plate 806. The scraper 807 contacts the surface of the PCB raw material to remove chips and remove excess impurities on the surface to ensure the processing quality of the plate.

[0029] The shape and material design of the scraper 807 are optimized, so that it can efficiently contact the surface of the PCB raw material and remove the chips without causing any damage to the surface of the PCB raw material.

[0030] After the second motor 801 is started, the power at its output end is transmitted to the rack plate 803 through the connecting gear 805. The meshing relationship between the connecting gear 805 and the rack plate 803 enables the rotation of the gear to directly drive the connecting frame 802 to reciprocate left and right along the limiting groove 804. As the connecting frame 802 moves left and right, the fixed plate 806 will also move synchronously. At this time, the scraper 807 on the fixed plate 806 contacts the surface of the PCB raw material to remove the waste on the surface of the PCB raw material.

[0031] Please see attached Figure 1 and attached Figure 3 A grinding assembly is installed on the top of the second mounting frame 4, and the grinding assembly includes a dual-axis motor 603, which is fixedly connected to the outside of the second mounting frame 4, one of the output ends of the dual-axis motor 603 is fixedly connected to a driving screw 601, the outer side of the driving screw 601 is threadedly connected to a threaded plate 604, the outer side of the threaded plate 604 is fixedly connected to a second cylinder 607, the output end of the second cylinder 607 is installed with a first motor 605, and the output end of the first motor 605 is fixedly connected to a grinding wheel 606.

[0032] Specifically, the driving screw 601 is driven to rotate by starting the dual-axis motor 603, so that the threaded plate 604 is moved left and right along the outer surface of the driving screw 601. At this time, the grinding wheel 606 is driven to rotate by starting the first motor 605. Through the telescopic action of the second cylinder 607, the grinding wheel 606 is moved to the notch of the cut PCB raw material for trimming.

[0033] Please see attached Figure 3 A guide rod 602 is slidably connected to the inner lower through hole of the threaded plate 604 , and the left and right ends of the guide rod 602 are fixedly connected to the inner wall of the second mounting frame 4 .

[0034] Specifically, the guide rod 602 allows the threaded plate 604 to move along its outer surface, thereby ensuring the stability of the guide rod 602 during movement.

[0035] Please see attached Figure 5 , Attachment Figure 6 and attached Figure 7 A connecting tube 705 is fixedly connected to one side of the top of the second mounting frame 4, a rubber piston 708 is slidably connected inside the connecting tube 705, a movable rod 703 is fixedly connected to the top of the rubber piston 708, a connecting plate 702 is fixedly connected to the top of the movable rod 703, a spring 704 is sleeved on the outside of the movable rod 703, an air intake pipe 707 is connected to the outside of the connecting tube 705, a connecting pipe 706 is also connected to the outside of the connecting tube 705, one end of the connecting pipe 706 is fixedly connected to an injection pipe 709, and an eccentric wheel 701 is fixedly connected to the other output end of the dual-axis motor 603.

[0036] The top of the spring 704 is fixedly connected to the outside of the connecting plate 702, the bottom of the spring 704 is fixedly connected to the outside of the connecting tube 705, and the outer surface of the eccentric wheel 701 contacts the outer surface of the connecting plate 702. Check valves are installed inside the connecting pipe 706 and the air inlet pipe 707, and the two check valves have opposite flow directions.

[0037] Specifically, the connecting cylinder 705 is a part of the second mounting frame 4, and a connecting cylinder 705 is fixedly connected to one side of the top thereof, which is used to accommodate the rubber piston 708. The space inside the connecting cylinder 705 can accommodate a certain amount of air or gas, which plays a role in regulating the airflow and pushing the piston.

[0038] The rubber piston 708 cooperates with the inside of the connecting tube 705 through a sliding connection, and can slide up and down along the inner wall of the connecting tube 705. The role of the rubber piston 708 is to drive the movable rod 703 to move up and down through the push of gas. The connecting plate 702 is fixedly connected to the movable rod 703, and realizes up and down swinging through contact with the eccentric wheel 701. The outer side of the connecting plate 702 is equipped with a spring 704, and the role of the spring 704 is to provide the necessary resilience to ensure that the connecting plate 702 can move accurately under the drive of the eccentric wheel 701. The part where the spring 704 is fixedly connected to the connecting plate 702 ensures its stability and precision. The air inlet pipe 707 is connected to the outer side of the connecting tube 705, and the outside air is introduced into the interior of the connecting tube 705 through the air inlet pipe 707. Under the action of the movable rod 703 and the rubber piston 708, the air inlet pipe 707 ensures the smooth flow of air and provides support for subsequent gas discharge.

[0039] During the trimming or grinding process, after the dual-axis motor 603 is started, the eccentric wheel 701 is driven to rotate through the output end. The eccentric wheel 701 contacts the outer surface of the connecting plate 702, and the connecting plate 702 swings up and down through its eccentric rotation. When the connecting plate 702 moves up and down, the spring 704 and the movable rod 703 located below it will also move synchronously.

[0040] Upward movement: When the connecting plate 702 moves upward, the movable rod 703 drives the rubber piston 708 to slide upward along the inner wall of the connecting tube 705. At this time, the outside air enters the interior of the connecting tube 705 through the air inlet pipe 707, and the gas is filled to provide power for subsequent actions.

[0041] Downward movement: When the connecting plate 702 moves downward, the rubber piston 708 squeezes out the air inside the connecting tube 705 and discharges it into the air jet pipe 709 through the connecting pipe 706. The air jet pipe 709 sprays the gas onto the surface of the grinding wheel 606, and blows away the metal debris and dust generated during the grinding process with the help of the air flow, thereby keeping the grinding disc clean and ensuring that the equipment continues to work efficiently.

[0042] In addition, both the connecting pipe 706 and the air inlet pipe 707 are provided with one-way valves. The design of these one-way valves ensures that the airflow can only flow in a specified direction, avoids reverse interference of the airflow, and ensures that the airflow control during the working process is accurate and effective.

[0043] It also includes a conveyor belt 1, which is used to transport PCB raw materials.

[0044] Specifically, the conveyor belt 1 is composed of a continuous conveyor belt, the upper surface of the conveyor belt 1 is used to carry the cut PCB raw materials, and the lower surface is connected to the driving mechanism to drive the conveyor belt 1 to move in a horizontal or inclined direction. The conveyor belt 1 is provided with a plurality of rollers or roller shafts, and under the action of the power system, these roller shafts enable the conveyor belt 1 to run smoothly.

[0045] By starting the driving motor, the conveyor belt 1 is driven to move forward. The upper surface of the conveyor belt 1 stably transports the cut PCB raw materials to the next workstation, avoiding manual handling and intervention, and improving work efficiency.

[0046] During use, the cut PCB raw materials are usually automatically moved from the cutting area of ​​the trimming equipment to the starting end of the conveyor belt 1. When the conveyor belt 1 is started, the power system drives the conveyor belt 1 to move through the driving wheel or the motor, so that the PCB raw materials are smoothly transported along the surface of the conveyor belt 1 toward the target area. Since the upper surface of the conveyor belt 1 is generally designed with a flat transmission platform, it can effectively prevent the PCB raw materials from sliding or tilting, ensuring its stability.

[0047] Please see attached Figure 1 and attached Figure 4 The outer side of the connecting gear 805 is meshed with the outer side of the rack plate 803, and the inner side of the fixed plate 806 is fixedly connected with a scraper 807. The jet pipe 709 is fixedly connected to the outer side of the threaded plate 604, and the other end of the driving screw 601 is movably connected to the inner wall of the second mounting frame 4 through a bearing.

[0048] Specifically, when the connecting gear 805 rotates, the connecting gear 805 will mesh with the rack plate 803, so as the connecting gear 805 rotates, the connecting frame 802 is driven to move synchronously. The threaded plate 604 provides an installation position for the jet tube 709, and the driving screw 601 is connected through a bearing to ensure the stability of the driving screw 601 during rotation.

[0049] Working principle: It includes the following steps: Step 1: Start the conveyor belt 1 to transport the cut PCB raw materials on the upper surface of the conveyor belt 1. At this time, the clamping assembly located outside the electric slider 503 works, and the double-sided rack 508 is driven to move along the inner wall of the fixed column 502 by starting the first cylinder 509. During the movement of the double-sided rack 508, the two driving gears 507 are driven to rotate, and the two clamping plates 506 are further driven to rotate, so that the rubber clamping plate at the bottom of the clamping plate 506 contacts the outer surface of the PCB raw material, so that the PCB raw material can be effectively clamped and fixed, so that the device can be automatically adjusted according to the different sizes and thicknesses of the plate; Step 2: Start the electric turntable 501 to drive the electric guide rail 504 to rotate 90 degrees, and move the cut PCB raw material to the grinding assembly. At this time, start the dual-axis motor 603 to drive the driving screw 601 to rotate, so that the threaded plate 604 moves left and right along the outer surface of the driving screw 601. At this time, start the first motor 605 to drive the grinding wheel 606 to rotate. Under the telescopic action of the second cylinder 607, the grinding wheel 606 is moved to the notch of the cut PCB raw material to trim it; Step 3: During the trimming process, the eccentric wheel 701 is driven to rotate by starting the dual-axis motor 603. Since the eccentric wheel 701 is in contact with the connecting plate 702, the connecting plate 702 moves up and down with the rotation of the eccentric wheel 701, thereby driving the spring 704 to move synchronously. When the movable rod 703 moves upward, it drives the rubber piston 708 to move upward along the inner wall of the connecting cylinder 705. At this time, the outside air enters the interior of the connecting cylinder 705 through the air inlet pipe 707. When the rubber piston 708 moves downward, the rubber piston 708 injects the air inside the connecting cylinder 705 into the jet pipe 709 through the connecting pipe 706, and sprays it on the outer surface of the grinding wheel 606 through the jet pipe 709, so that the debris generated on the outer surface of the grinding wheel 606 is automatically cleaned, so that the efficient working state of the grinding disc can be maintained in real time, and the consistency and stability of the grinding and trimming effect of the PCB raw materials can be ensured; Step 4: After the trimming is completed, the electric turntable 501 is started again to drive the electric guide rail 504 to rotate 90 degrees, and the PCB raw material after the trimming is completed is moved to the cleaning component. At this time, the second motor 801 is started to drive the connecting gear 805 to rotate. Since the connecting gear 805 and 803 are meshed with each other, the rotation of the connecting gear 805 will cause the connecting frame 802 to reciprocate left and right along the inner wall of the limiting groove 804, thereby driving the fixed plate 806 to move synchronously, and the scraper 807 is used to remove the chips of the polished PCB raw material; Step 5. After cleaning is completed, the PCB raw material is moved to the top of the placement rack 2, the clamping component finishes working, and the electric telescopic rod outside the electric slider 503 is started to unload the PCB raw material into the placement rack 2, thus completing the automatic loading, automatic grinding, automatic cleaning and automatic unloading of the PCB raw material.

10. A method for using a patch processing device suitable for PCB raw material production, according to the patch processing device suitable for PCB raw material production according to any one of claims 1-9, characterized in that: The following steps are involved: Step 1: Start the conveyor belt (1) to transport the PCB raw materials on the upper surface of the conveyor belt (1). At this time, the clamping assembly located outside the electric slider (503) works, and the double-sided rack (508) is driven to move along the inner wall of the fixed column (502) by starting the first cylinder (509). During the movement of the double-sided rack (508), the two driving gears (507) are driven to rotate, and the two clamping plates (506) are further driven to rotate, so that the rubber clamping plate at the bottom of the clamping plate (506) contacts the outer surface of the PCB raw material and clamps it; Step 2: Start the electric turntable (501) to drive the electric guide rail (504) to rotate 90 degrees, move the cut PCB raw material to the grinding assembly, and use the grinding assembly to grind the PCB raw material; Step 3: During the trimming process, the eccentric wheel (701) is driven to rotate by starting the dual-axis motor (603). Since the eccentric wheel (701) and the connecting plate (702) are in contact with each other, the connecting plate (702) moves up and down with the rotation of the eccentric wheel (701), thereby driving the spring (704) to move synchronously. When the movable rod (703) moves upward, it drives the rubber piston (708) to move upward along the inner wall of the connecting cylinder (705). At this time, the outside air enters the interior of the connecting cylinder (705) through the air inlet pipe (707). When the rubber piston (708) moves downward, the rubber piston (708) injects the air inside the connecting cylinder (705) into the jet pipe (709) through the connecting pipe (706), and sprays the air onto the outer surface of the grinding wheel (606) through the jet pipe (709), thereby automatically cleaning the debris generated on the outer surface of the grinding wheel (606); Step 4: After the trimming is completed, the electric turntable (501) is started again to drive the electric guide rail (504) to rotate 90 degrees, and the PCB raw material after the trimming is completed is moved to the cleaning component. At this time, the second motor (801) is started to drive the connecting gear (805) to rotate, so that the connecting frame (802) reciprocates left and right along the inner wall of the limiting groove (804), thereby driving the fixed plate (806) to move synchronously, and the scraper (807) is used to remove the chips of the polished PCB raw material; Step 5: After cleaning is completed, the PCB raw material is moved to the top of the placement rack (2), the clamping assembly finishes working, and the electric telescopic rod outside the electric slider (503) is started to place the PCB raw material inside the placement rack (2), completing automatic unloading.
