Description

Technical Field

[0001] The present invention relates to the field of PCB processing equipment, and specifically to a chip mounting processing device and method applicable to the production of PCB raw materials. Background Art

[0002] With the continuous development of electronic products and the increasing demand for integration, as the core basic component of electronic products, PCB plays a crucial role in various electronic devices. The production process of PCB includes multiple processes, among which chip mounting processing is one of the key links. Traditional PCB raw material chip mounting processing equipment usually relies on the combination of manual operation and mechanical means, such as manual loading, manual grinding, manual cleaning, and manual unloading. Although this traditional production method can complete basic chip mounting processing tasks, there are still many limitations and deficiencies, and urgent improvement is needed.

[0003] Firstly, in the existing chip mounting processing equipment, the manual operation links are cumbersome and inefficient. Manual loading and handling require a lot of time and labor, which easily leads to delays and instability in the production process and reduces production efficiency.

[0015] A usage method of a chip processing device applicable to PCB raw material production includes the following steps:

[0016] Step 1: Start the conveyor belt to drive the transportation of the PCB raw material on the upper surface of the conveyor belt. At this time, the clamping component outside the electric slider works. Start the first cylinder to drive the double-sided rack to move along the inner wall of the fixed column. During the movement of the double-sided rack, drive the two driving gears to rotate, further drive the two clamping plates to rotate, and make the rubber clamping plate at the bottom of the clamping plate contact the outer surface of the PCB raw material and clamp it.

[0017] 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 component, and use the grinding component to grind the PCB raw material.

[0018] Step 3: During the trimming process, starting the double-shaft motor will drive the eccentric wheel to rotate. Since the eccentric wheel is in contact with the connecting plate, the connecting plate will move up and down with the rotation of the eccentric wheel, thus driving the spring to move synchronously. When the movable rod moves upward, drive the rubber piston to move upward along the inner wall of the connecting cylinder. At this time, the outside air enters the inside of the connecting cylinder through the air inlet pipe.

[0019] Step 4: After trimming, start the electric turntable again to drive the electric guide rail to rotate 90 degrees, move the trimmed PCB raw material to the cleaning component. At this time, start the second motor to drive the connecting gear to rotate, so that the connecting frame moves left and right reciprocally along the inner wall of the limit groove, thus driving the fixed plate to move synchronously, and use the scraper to remove the chips from the ground PCB raw material.

[0020] Step 5: After cleaning, move the PCB raw material above the placement rack, the clamping component stops working, and start the electric telescopic rod outside the electric slider to place the PCB raw material inside the placement rack to complete automatic blanking.

[0021] The present invention provides a chip processing device and method applicable to the production of PCB raw materials. It has the following

[0022] Beneficial effects:

[0023] 1.

Specific embodiments

[0035] Next, in combination with the accompanying drawings of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to the attached Figure 1 -attached 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 rack 3, a second mounting rack 4 and a placement rack 2. An electric guide rail 504 is installed on the top of the electric turntable 501, an electric slider 503 is installed outside 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, the output end of the first cylinder 509 is fixedly connected to a double-sided rack 508, two driving gears 507 are movably connected to the inside of the fixed column 502 through bearings, a clamping plate 506 is fixedly connected to the outside of the driving gear 507, the outside of both driving gears 507 is meshed with the outside of the double-sided rack 508, and an electric telescopic rod is installed outside the connecting frame 505. A cleaning component is installed on the top of the first mounting rack 3.

[0037] Specifically, after the device 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 frame 505 to move to the required position.

[0038] Clamping operation: Start the first cylinder 509. The cylinder slides the double-sided rack 508 along the inner wall of the fixed column 502 by pushing. The double-sided rack 508 drives the driving gear 507 to rotate, and clamps the PCB raw material through the clamping plate 506. The rubber clamping plate is in close contact with the surface of the PCB raw material, effectively preventing the plate from moving or skewing.

[0039] Please refer to the appendix Figure 1 and the appendix Figure 4 As shown in the figure, the cleaning component includes a rack plate 803. The rack plate 803 is fixedly connected to the top of the first mounting bracket 3. A limiting groove 804 is formed 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. An output end of the second motor 801 is fixedly connected to a connecting gear 805. Two fixing plates 806 are fixedly connected to the outer side of the connecting frame 802.

[0040] Specifically, the limiting groove 804 is used to limit the movement track of the connecting frame 802, ensuring the stability and accuracy of its movement. The design of the inner wall of the limiting groove 804 enables the connecting frame 802 to slide therein, and limits its displacement range through mechanical cooperation, thereby ensuring the precise movement of the connecting frame 802.

[0041] The second motor 801 is the power source of the drive 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 and operation of the motor can drive the entire device to work, ensuring the continuous progress of the chip removal process.

[0042] The fixing plate 806 is a component fixedly connected to the connecting frame 802. Through the reciprocating movement of the connecting frame 802, the fixing plate 806 can move synchronously and move along the specified track. A scraping plate 807 is arranged on the outer side of the fixing plate 806. The scraping plate 807 contacts the surface of the PCB raw material to perform chip removal treatment, removing the excess impurities on the surface and ensuring the processing quality of the plate.

[0043] The shape and material design of the scraping plate 807 are optimized, and it can efficiently contact the surface of the PCB raw material and remove chips without causing any damage to the surface of the PCB raw material.

[0044] After starting the second motor 801, 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 perform left-right reciprocating movement along the limiting groove 804. As the connecting frame 802 moves left and right, the fixing plate 806 will also move synchronously. At this time, the scraping plate 807 on the fixing plate 806 contacts the surface of the PCB raw material, and removes the waste chips on the surface of the PCB raw material.

[0045] Please refer to the attached Figure 1 and the attached Figure 3 , a grinding component is installed on the top of the second mounting bracket 4. The grinding component includes a biaxial motor 603. The biaxial motor 603 is fixedly connected to the outside of the second mounting bracket 4. One output end of the biaxial motor 603 is fixedly connected to a driving screw 601. A threaded plate 604 is threadedly connected to the outside of the driving screw 601. A second cylinder 607 is fixedly connected to the outside of the threaded plate 604. A first motor 605 is installed at the output end of the second cylinder 607. A grinding wheel 606 is fixedly connected to the output end of the first motor 605.

[0046] Specifically, by starting the biaxial motor 603 to drive the driving screw 601 to rotate, the threaded plate 604 is moved left and right along the outer surface of the driving screw 601. At this time, by starting 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 for trimming.

[0047] Please refer to the attached Figure 3 , a guide rod 602 is slidably connected to the lower through hole inside the threaded plate 604. Both the left and right ends of the guide rod 602 are fixedly connected to the inner wall of the second mounting bracket 4.

[0048] Specifically, the guide rod 602 allows the threaded plate 604 to move along its outer surface, ensuring the stability of the threaded plate 604 during movement.

[0049] Please refer to the attached Figure 5 , the attached Figure 6 and the attached Figure 7 , one side of the top end of the second mounting bracket 4 is fixedly connected to a connecting cylinder 705. A rubber piston 708 is slidably connected to the inside of the connecting cylinder 705. A movable rod 703 is fixedly connected to the top end of the rubber piston 708. A connecting plate 702 is fixedly connected to the top end of the movable rod 703. A spring 704 is sleeved on the outside of the movable rod 703. An air inlet pipe 707 is communicated with the outside of the connecting cylinder 705. A connecting pipe 706 is also communicated with the outside of the connecting cylinder 705. One end of the connecting pipe 706 is fixedly connected to a jet pipe 709. The other output end of the biaxial motor 603 is fixedly connected to an eccentric wheel 701.

[0050] The top end of the spring 704 is fixedly connected to the outside of the connecting plate 702, and the bottom end of the spring 704 is fixedly connected to the outside of the connecting cylinder 705. The outer surface of the eccentric wheel 701 is in contact with the outer surface of the connecting plate 702. Check valves are installed inside both the connecting pipe 706 and the air inlet pipe 707, and the flow directions of the two check valves are opposite.

[0051] Specifically, the connecting cylinder 705 is a part of the second mounting bracket 4. A connecting cylinder 705 is fixedly connected to one side of its top, 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, playing a role in regulating the air flow and pushing the piston.

[0052] The rubber piston 708 is in internal cooperation with the connecting cylinder 705 through a sliding connection and can slide up and down along the inner wall of the connecting cylinder 705. The function of the rubber piston 708 is to drive the up and down movement of the movable rod 703 by the push of gas. The connecting plate 702 is fixedly connected to the movable rod 703 and swings up and down by contacting the eccentric wheel 701. A spring 704 is installed on the outer side of the connecting plate 702. The function of the spring 704 is to provide the necessary resilience to ensure that the connecting plate 702 can move precisely 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 cylinder 705, and outside air is introduced into the inside of the connecting cylinder 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.

[0053] During the trimming or grinding process, after the dual-axis motor 603 is started, it drives the eccentric wheel 701 to rotate through the output end. The eccentric wheel 701 contacts the outer surface of the connecting plate 702, and makes the connecting plate 702 swing up and down through its eccentric rotation action. When the connecting plate 702 moves up and down, the spring 704 and the movable rod 703 located below it will also move synchronously.

[0054] 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 cylinder 705. At this time, outside air enters the inside of the connecting cylinder 705 through the air inlet pipe 707, and the charged gas provides power for subsequent actions.

[0055] Downward movement: When the connecting plate 702 moves downward, the rubber piston 708 will squeeze out the air inside the connecting cylinder 705 and discharge it into the jet pipe 709 through the connecting pipe 706. The jet pipe 709 will spray the gas onto the surface of the grinding wheel 606, and blow away the metal chips and dust generated during the grinding process by means of the air flow, thereby keeping the grinding disc clean and ensuring the continuous and efficient operation of the equipment.

[0056] In addition, one-way valves are provided inside both the connecting pipe 706 and the air inlet pipe 707. The design of these one-way valves ensures that the air flow can only flow in the specified direction, avoiding reverse air flow interference and ensuring precise and effective air flow control during the working process.

[0057] It also includes a conveyor belt 1, which is used to transport PCB raw materials.

[0058] 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 drives the conveyor belt 1 to move in the horizontal or inclined direction by connecting with the driving mechanism. The conveyor belt 1 is provided with a plurality of rollers or rollers, and under the action of the power system, these rollers enable the conveyor belt 1 to run smoothly.

[0059] By starting the drive motor, the drive drives the forward movement of the conveyor belt 1. The upper surface of the conveyor belt 1 steadily transports the cut PCB raw materials to the next workstation, avoiding manual handling and intervention, and improving work efficiency.

[0060] During use, the cut PCB raw materials are usually automatically transferred 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 start moving through the drive wheel or the motor, causing the PCB raw materials to be smoothly transported along the surface of the conveyor belt 1 towards 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 sliding or tilting of the PCB raw materials and ensure their stability.

[0061] Please refer to the attached Figure 1 and the attached Figure 4 . The outer side of the connecting gear 805 is meshed and connected with the outer side of the rack plate 803, and the inner side of the fixing plate 806 is fixedly connected with a scraping plate 807. The air spraying 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 bracket 4 through a bearing.

[0062] Specifically, when the connecting gear 805 rotates, the connecting gear 805 meshes with the rack plate 803. Therefore, as the connecting gear 805 rotates, it drives the connecting frame 802 to move synchronously. The threaded plate 604 provides an installation position for the air spraying pipe 709, and the driving screw 601 is connected through a bearing, ensuring the stability of the driving screw 601 during rotation.

[0063] Working principle: It includes the following steps:

[0064] Step 1: By starting the conveyor belt 1, drive the cut PCB raw materials on the upper surface of the conveyor belt 1 for transportation. At this time, the clamping assembly located outside the electric slider 503 works. By starting the first cylinder 509, drive the double-sided rack 508 to move along the inner wall of the fixed column 502. During the movement of the double-sided rack 508, drive the two driving gears 507 to rotate, further drive the two clamping plates 506 to deflect, and make the rubber clamping plate at the bottom of the clamping plate 506 contact the outer surface of the PCB raw materials. In this way, the PCB raw materials can be effectively clamped and fixed, enabling the device to automatically adjust according to the different sizes and thicknesses of the plates.

[0065] 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 double-shaft motor 603 to drive the drive screw 601 to rotate, so that the threaded plate 604 moves left and right along the outer surface of the drive 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, move the grinding wheel 606 to the notch of the cut PCB raw material for trimming;

[0066] Step 3: During the trimming process, starting the double-shaft motor 603 will drive the eccentric wheel 701 to rotate. Since the eccentric wheel 701 is in contact with the connecting plate 702, the connecting plate 702 will move up and down with the rotation of the eccentric wheel 701, so as to drive 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 inside 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 spray pipe 709 through the connecting pipe 706 and sprays it on the outer surface of the grinding wheel 606 to automatically clean the debris generated on the outer surface of the grinding wheel 606, so as to maintain the efficient working state of the grinding disc in real time and ensure the consistency and stability of the grinding and trimming effect of the PCB raw material;

[0067] Step 4: After trimming is completed, start the electric turntable 501 again to drive the electric guide rail 504 to rotate 90 degrees, and move the trimmed PCB raw material to the cleaning assembly. At this time, start the second motor 801 to drive the connecting gear 805 to rotate. Since the connecting gear 805 meshes with the rack plate 803, the rotation of the connecting gear 805 will move the connecting frame 802 left and right reciprocally along the inner wall of the limit groove 804, so as to drive the fixed plate 806 to move synchronously, and use the scraper 807 to remove debris from the ground PCB raw material;

[0068] Step 5: After cleaning is completed, move the PCB raw material above the placement rack 2, the clamping assembly stops working, and start the electric telescopic rod outside the electric slider 503 to unload the PCB raw material into the inside of the placement rack 2, so as to complete the automatic loading, automatic grinding, automatic cleaning and automatic unloading effects of the PCB raw material. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.

7. A method of using a chip mounting processing device suitable for PCB raw material production, according to any one of claims 1-6, a chip mounting processing device suitable for PCB raw material production, characterized in that, It includes the following steps: Step 1: By starting the conveyor belt (1), the PCB raw materials on the upper surface of the conveyor belt (1) are driven for transportation. At this time, the clamping assembly outside the electric slider (503) works. By starting the first cylinder (509), the double-sided rack (508) is driven to move along the inner wall of the fixed column (502). During the movement of the double-sided rack (508), the two driving gears (507) are driven to rotate, further driving the two clamping plates (506) to deflect, and the rubber clamping plates at the bottom of the clamping plates (506) are brought into contact with the outer surface of the PCB raw materials and clamp them. Step 2: By starting the electric turntable (501), the electric guide rail (504) is driven to rotate by 90 degrees, and the cut PCB raw materials are moved to the grinding assembly, and the PCB raw materials are ground by the grinding assembly. Step 3: During the trimming process, the start of the double-axis motor (603) drives the eccentric wheel (701) to rotate. 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), thus 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, external air enters the inside 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 spray pipe (709) through the connecting pipe (706), and sprays it on the outer surface of the grinding wheel (606) through the spray pipe (709) to automatically clean the debris generated on the outer surface of the grinding wheel (606). Step 4: After the trimming is completed, start the electric turntable (501) again to drive the electric guide rail (504) to rotate 90 degrees, and move the trimmed PCB raw material to the cleaning component. At this time, start the second motor (801) to drive the connecting gear (805) to rotate, so that the connecting frame (802) moves left and right reciprocally along the inner wall of the limit groove (804), thus driving the fixed plate (806) to move synchronously, and using the scraper (807) to remove the chips from the polished PCB raw material. Step 5: After the cleaning is completed, move the PCB raw material above the placement rack (2), the clamping component stops working, and start the electric telescopic rod outside the electric slider (503) to place the PCB raw material inside the placement rack (2) to complete automatic blanking.
