Description

Technical Field

[0001] The invention relates to the technical field of stacking, and in particular to a PCB cutting and stacking machine with controllable stacking height. Background Art

[0002] Soft sheets such as polypropylene (PP) sheets, copper foils, centrifugal films, etc. commonly used in PCB manufacturing are formed into sheets wound on a rod. Various manufacturers cut and stack them for use. The cutting and stacking systems currently used are all for cutting and stacking single roll sheets. However, in general use, two sheets of different thicknesses or materials are often stacked and pressed together for use. This requires manual recombination and stacking of various sheets of a single material after cutting and stacking. Due to the thin thickness and large area of ​​the sheets, it is easy to cause uneven stacking and bumps, and it requires a lot of manual work.

[0003] Before stacking, the surface of the PCB board is cleaned manually. It is difficult to ensure consistency in the manual cleaning process. Different operators will have different cleaning standards and strengths, resulting in uneven cleaning effects, affecting the stability of product quality. When using manual tools (such as brushes, sponges, etc.) for cleaning, if the operation is improper, the surface of the PCB board will be scratched, causing damage to the circuit or destruction of the oxide layer, affecting the performance and life of the circuit board. Chemical cleaners are used in the manual cleaning process. If the operation is improper or the cleaner remains, it will contaminate the PCB board or subsequent electronic components and affect their performance. Long-term contact with certain cleaners will have an impact on human health, such as skin irritation, respiratory problems, etc. In addition, improper operation may also cause fire or explosion risks. For some difficult-to-remove stains or contaminants, manual cleaning cannot achieve the ideal cleaning effect, especially for precise microstructures or deep dirt.

[0004] In the prior art, the sheets of a single material are manually reassembled and stacked after being cut and stacked, and the accuracy of manual operation is affected by factors such as the operator's skills, attention, and fatigue, making it difficult to achieve a high degree of accuracy. The stacking height of the PCB needs to be very precise to ensure the reliability of the circuit connection. The inaccuracy of manual operation can lead to problems such as circuit short circuits and poor contact. The differences in operation between different operators can lead to consistency problems in the stacking height, which not only affects production efficiency, but also affects the consistency of product quality, which is not conducive to product standardization and mass production. The speed of manual operation is limited, and rest is required, which limits the production speed and leads to low production efficiency. On high-volume production lines, manual operation cannot meet the demand. In the PCB production process, there are risks such as chemical substances and high voltage. Manual operation increases the operator's chance of being exposed to these risks, thereby affecting the operator's safety. The quality control of manual operation depends on the operator's monitoring and judgment of the process, which makes it difficult to achieve comprehensive and systematic quality control, especially for complex products or production lines.

[0005] Therefore, a PCB cutting and laminating machine with controllable stacking height is proposed to solve the above problems. Summary of the invention

[0006] In view of this, the technical problem to be solved by the present invention is to propose a PCB cutting and stacking machine with controllable stacking height, so as to solve the problem that it is difficult to ensure consistency in the manual cleaning process of the prior art, different operators will have different cleaning standards and strengths, resulting in uneven cleaning effects, affecting the stability of product quality, and when using manual tools (such as brushes, sponges, etc.) for cleaning, if the operation is improper, the surface of the PCB board will be scratched, resulting in damage to the circuit or destruction of the oxide layer, affecting the performance and life of the circuit board, and the accuracy of manual operation is affected by factors such as the operator's skills, attention, and fatigue level, and it is difficult to achieve a high degree of accuracy.

[0017] Compared with the prior art, the present invention provides a PCB cutting and laminating machine with controllable stacking height, which has the following beneficial effects:

[0018] 1. Through the cooperation between the first rotation, bevel gear set, second roller, first cylinder, disc, second cylinder, third cylinder and spray barrel in the auxiliary clamping mechanism, the cleaning agent can be sprayed to cover the surface of the PCB, which greatly improves the cleaning efficiency. Compared with manual cleaning, it not only saves time, but also reduces labor costs. It can ensure that the cleanliness of each PCB remains consistent, avoiding the inconsistency problem existing in manual operation, which helps to improve the stability of product quality. During manual operation, physical damage to the PCB may be caused due to improper force or improper tools. Since the pressure distribution of the roller is relatively uniform when rolling, that is, the rolling action of the roller is relatively gentle, it will not cause damage to the metal layer or coating of the PCB board, so the auxiliary clamping mechanism can reduce such risks by spraying cleaning agent and wiping with rollers. The auxiliary clamping mechanism can reduce the direct contact between operators and harmful cleaning agents, reduce health risks, and reduce the risk of accidents caused by improper operation.

[0019] 2. The first roller and the second scraper in the auxiliary clamping mechanism cooperate with each other to smooth the coating after applying the conformal coating. Since air is mixed into the conformal coating during storage or transportation, the air is squeezed out to form bubbles during application. Smoothing can eliminate bubbles in the coating, ensure that the coating surface is smooth and free of bubbles, and improve the adhesion of the coating. During the drying process of the coating, the second scraper can help exhaust the air in the coating and reduce the generation of bubbles. The scraper can further ensure that the coating thickness is uniform and avoid local excessive thickness or thinness. The smooth coating surface can improve the appearance quality of the PCB board and make it more beautiful. The uniform and smooth coating can better protect the PCB board from environmental factors such as moisture, salt spray, chemical corrosion, etc. The smooth coating can reduce subsequent processing steps such as grinding and polishing, thereby saving time and cost.

[0020] 3. Through the cooperation between the telescopic frame, auxiliary frame, electric telescopic rod, clamping plate and height detector in the auxiliary stacking mechanism, the stacking height of the PCB board can be increased while clamping the PCB board on four sides to evenly apply pressure to prevent the PCB board from being deformed due to uneven external force during the processing. This is very important for maintaining the structural integrity and electrical performance of the PCB board. During the stacking process of the PCB board, the edge part is easily damaged. The protection of the four-sided clamping and telescopic frame can reduce the mechanical damage to the edge of the PCB board. Through the four-sided clamping, it can be ensured that the PCB board maintains the correct position and height during the stacking process, thereby improving the stacking accuracy and avoiding assembly problems caused by position offset.

A connecting rod 515 is rotatably connected to the side of the first slider 514, and an end of the connecting rod 515 away from the first slider 514 is rotatably connected to the second n-type auxiliary block 516. The inner wall of the second n-type auxiliary block 516 is rotatably connected to the first roller 517, and the inner wall of the second n-type auxiliary block 516 is fixedly connected to the second scraper 529.

[0043] An extension plate 518 is fixedly connected to a side of the first n-type auxiliary block 512 away from the clamping device 511, a first rotating column 519 is rotatably connected to the side of the extension plate 518, a bevel gear set 520 is fixedly connected to the outer surface of the first rotating column 519, a second roller 521 is fixedly connected to an end of the first rotating column 519 away from the extension plate 518, a first cylinder 522 is fixedly connected to an end of the bevel gear set 520 away from the first rotating column 519, and a disk 523 is fixedly connected to the top surface of the first cylinder 522.

[0045] In the prior art, the surface of the PCB board is cleaned manually. It is difficult to ensure consistency in the manual cleaning process. Different operators have different cleaning standards and strengths, resulting in uneven cleaning effects, affecting the stability of product quality. When using manual tools (such as brushes, sponges, etc.) for cleaning, if the operation is improper, the surface of the PCB board will be scratched, resulting in damage to the circuit or the oxide layer, affecting the performance and life of the circuit board. The first rotating column 519, the bevel gear set 520, the second roller 521, the first cylinder 522, the disc 523, the second cylinder 524, the third cylinder 525 and the spray barrel 527 in the auxiliary clamping mechanism are matched with each other. The cleaning agent can be sprayed to cover the surface of the PCB, which greatly improves the cleaning efficiency. Compared with manual cleaning, it not only saves time but also reduces labor costs. The automated process can ensure that the cleanliness of each PCB remains consistent, avoiding the inconsistency problems that exist during manual operation, which helps to improve the stability of product quality. During manual operation, physical damage to the PCB may be caused by improper force or improper tools. The auxiliary clamping mechanism can reduce such risks by spraying cleaning agents and wiping with rollers. The auxiliary clamping mechanism can reduce the direct contact between operators and harmful cleaning agents, reduce health risks, and reduce the risk of accidents caused by improper operation.

[0046] For further examples, please refer to Figures 7 to 10 As shown:

[0047] The auxiliary stacking mechanism comprises an outer frame 601, which is fixedly connected to the top surface of the base 1. A wedge-shaped fixing block 606 for keeping the PCB board stably placed is fixedly and slidably connected inside the outer frame 601.

[0048] The auxiliary overlapping mechanism also includes an auxiliary cylinder 602, which is slidably connected to the inside of the outer frame 601, and the top surface of the auxiliary cylinder 602 is fixedly connected to a sliding cylinder 603, and the top surface of the sliding cylinder 603 is fixedly connected to a placement plate 612, and the bottom surface of the auxiliary cylinder 602 is rotatably connected to a ball 604, and the inside of the outer frame 601 is slidably connected to the ball 604, and the ball 604 is located on the inclined surfaces of the wedge-shaped slider 605 and the wedge-shaped fixed block 606.

[0049] The top surface of the placement plate 612 is fixedly connected to a telescopic frame 607, the top surface of the telescopic frame 607 is fixedly connected to an auxiliary frame 608, the interior of the auxiliary frame 608 is movably connected to an electric telescopic rod 609, the side of the electric telescopic rod 609 away from the auxiliary frame 608 is fixedly connected to a splint 610, and the side of the auxiliary frame 608 is fixedly connected to a height detector 611.

[0050] The height detector 611 is electrically connected to the controller, and the controller controls the telescopic frame 607 to be telescopic, and controls the electric telescopic rod 609 to be telescopic.

[0051] In the prior art, the sheets of a single material are manually reassembled and stacked after being cut and stacked. However, the accuracy of manual operation is affected by factors such as the operator's skills, attention, and fatigue level, and it is difficult to achieve a high degree of accuracy. The stacking height of the PCB needs to be very precise to ensure the reliability of the circuit connection. The inaccuracy of manual operation may lead to problems such as circuit short circuit and poor contact. The operation differences between different operators may lead to the problem of consistency of the stacking height, which not only affects the production efficiency, but also affects the consistency of product quality, which is not conducive to the standardization and mass production of products. Compared with the prior art, the telescopic auxiliary stacking mechanism can achieve the desired effect. The frame 607, the auxiliary frame 608, the electric telescopic rod 609, the clamping plate 610 and the height detector 611 cooperate with each other. The four-sided clamping can apply pressure evenly to prevent the PCB board from being deformed due to uneven external force during the processing. This is very important for maintaining the structural integrity and electrical performance of the PCB board. During the stacking process of the PCB boards, the edge parts are easily damaged. The protection of the four-sided clamping and the telescopic frame 607 can reduce the mechanical damage to the edges of the PCB boards. Through the four-sided clamping, it can be ensured that the PCB board maintains the correct position and height during the stacking process, thereby improving the stacking accuracy and avoiding assembly problems caused by position offset.

[0052] Everything in the above example works like this:

[0053] In the initial state: the interior of the second cylinder 524 is filled with conformal coating, the interior of the third cylinder 525 is filled with cleaning agent, and the PCB board is placed on the top surface of the conveying device 3 .

[0054] The following is the working process of the auxiliary clamping mechanism to pick up the PCB board:

[0055] When in use, the sliding device 4 can move freely on the side of the auxiliary plate 2. When the sliding device 4 controls the auxiliary clamping mechanism to move toward the conveying device 3, and the auxiliary clamping mechanism is just located above the PCB board, at this time, the motor drives the first rotating column 519 to rotate, and the rotation of the first rotating column 519 drives the bevel gear set 520 fixedly connected thereto to rotate, and the rotation of the bevel gear set 520 drives the first cylinder 522 fixedly connected thereto to rotate, and the rotation of the first cylinder 522 drives the disk 523 fixedly connected thereto. An annular push block is slidably connected at the center of the circle, and piston push plates are fixedly connected on both sides of the annular push block, and are slidably connected to the inside of the second cylinder 524 and the third cylinder 525, that is, the rotation of the disk 523 drives the annular push block to reciprocate inside the second cylinder 524 and the third cylinder 525, and then the three-proof paint inside the second cylinder 524 is pushed into the hose 526, and the three-proof paint is injected into the inside of the first roller 517 through the hose 526, and the cleaning agent in the third cylinder 525 is sprayed onto the surface of the PCB board through the spray barrel 527. A rotating column 519 is driven to rotate by a motor, that is, the rotation of the first rotating column 519 drives the second roller 521 fixedly connected thereto to rotate. The rotation of the second roller 521 will roll and wipe the place where the detergent has been sprayed, and the first scraper 528 is fixedly connected to the inside of the extension plate 518. After the PCB board is rolled and scrubbed by the second roller 521, the first scraper 528 is used to scrape and remove the residual detergent. The sprayed detergent can cover the surface of the PCB, which greatly improves the cleaning efficiency. Compared with manual cleaning, it not only saves time but also reduces labor costs. The automated process can ensure that the cleaning degree of each PCB is consistent, avoiding the inconsistency problem existing in manual operation, which helps to improve the stability of product quality. During manual operation, physical damage to the PCB may be caused by improper force or improper tools. The auxiliary clamping mechanism can reduce such risks by spraying detergent and wiping with rollers. The auxiliary clamping mechanism can reduce the direct contact between operators and harmful detergents, reduce health risks, and reduce the risk of accidents caused by improper operation.

[0056] After cleaning the surface of the PCB board, since the hose 526 is fixedly connected to the first roller 517, the conformal coating is discharged to the inside of the first roller 517 through the hose 526, and then the conformal coating is applied to the cleaned PCB board through the first roller 517, and the second scraper 529 is fixedly connected to the inside of the first n-type auxiliary block 512, and then the coated conformal coating is smoothed. Since air is mixed into the conformal coating during storage or transportation, the air is squeezed out to form bubbles during application, and smoothing can eliminate bubbles in the coating, ensure that the coating surface is smooth and free of bubbles, and improve the adhesion of the coating. During the drying process of the coating, the second scraper 529 can help discharge the air in the coating and reduce the generation of bubbles. The scraper can further ensure that the coating thickness is uniform, avoiding local excessive thickness or thinness, and the smooth coating surface can improve the appearance quality of the PCB board and make it more beautiful. The uniform and smooth coating can better protect the PCB board from environmental factors such as moisture, salt spray, chemical corrosion, etc. The smooth coating can reduce subsequent processing steps such as grinding and polishing, thereby saving time and cost;

[0057] When the thickness of the conformal coating applied to the PCB needs to be adjusted, when the motor drives the reciprocating screw 513 to rotate forward, the reciprocating screw 513 drives the two first sliders 514 threadedly connected thereto to move toward each other, and the first sliders 514 move toward each other to drive the connecting rod 515 rotatably connected thereto to rotate, and the connecting rod 515 rotates to drive the second n-type auxiliary block 516 rotatably connected thereto to move downward, and vice versa, the reciprocating screw 513 is reversed, and the second n-type auxiliary block 516 moves upward, thereby adjusting. The main function of the conformal coating is to protect the PCB from environmental factors such as moisture, dust, salt spray, and mold. By adjusting the coating thickness, it is possible to ensure that key electronic components and connection points are fully protected, because After drying, the conformal coating forms a uniform protective layer, which tightly covers the surface of the electronic components to form a physical barrier. It can also fill gaps and pores to prevent moisture, dust and other pollutants from entering the interior of the PCB board, thereby reducing the failure rate and extending the life of the device. Proper control of the coating thickness of the conformal coating can avoid its negative impact on the heat dissipation performance of the PCB. An overly thick conformal coating layer will hinder the dissipation of heat and cause the device to overheat. By adjusting the thickness, the PCB is protected from environmental influences without affecting its heat dissipation performance. Subsequently, the cleaned and conformal coating PCB board is clamped by the clamping device 511, and then the PCB board is placed on the top surface of the placement plate 612 by moving the sliding device 4.

[0058] When the sliding device 4 encounters vibration during the movement, it will drive the connecting block 501 to vibrate together. The vibration of the connecting block 501 drives the first supporting plate 502 and the arc-shaped curved plate 503 fixedly connected thereto to vibrate together. Since the other end of the arc-shaped curved plate 503 is rotatably connected to the second supporting plate 508, the second supporting plate 508 is rotatably connected to the first fixed block 510 on the side close to the auxiliary plate 2, and the first fixed block 510 is fixedly connected to the first sliding rod 509 on the side away from the second supporting plate 508. The top surface of the connecting plate 504 is rotatably connected to the first rotating block 505, and the first rotating block 505 is fixedly connected to the first cylinder 506 on the side away from the connecting plate 504, and the first sliding rod 509 is connected to the first cylinder 506. 06 sliding connection, there is a cavity in the first cylinder 506, and a first return spring 507 is fixedly connected between the first rotating block 505 and the first fixed block 510, that is, when the sliding device 4 vibrates, due to the action of the cavity of the first cylinder 506 and the first return spring 507, the vibration of the clamping device 511 will be reduced, and then the vibration of the PCB board clamped by the clamping device 511 will be reduced. Reducing vibration can ensure the stable position of the PCB board during the processing, thereby improving the accuracy and consistency of the circuit. Stable movement can reduce problems such as circuit breakage and short circuit caused by vibration, thereby improving product reliability. Vibration can cause damage to equipment. Reducing vibration can reduce equipment wear and extend the service life of the equipment.

[0060] The following is the working process of the auxiliary stacking mechanism controlling the stacking height:

[0061] When in use, when the PCB board is placed on the top surface of the placement plate 612, due to the effect of the center of gravity, the placement plate 612 will tilt slightly as the PCB board is placed. When the placement plate 612 tilts, it will drive the auxiliary cylinder 602 to move downward, and the auxiliary cylinder 602 moves downward, driving the ball 604 movably connected thereto to move downward together. Since the ball 604 is located on the inclined surface opposite to the wedge-shaped slider 605 and the wedge-shaped fixing block 606, the downward movement of the ball 604 pushes the wedge-shaped slider 605 to slide to the other side, and then pushes the ball 604 and the auxiliary cylinder 602 on the other side to move upward. However, since the gravity on the placement plate 612 is consistent, that is, after the ball 604 and the auxiliary cylinder 602 on the other side move upward, they will move downward due to the influence of gravity. Therefore, the two ball 604 and the auxiliary cylinder 602 will move downward after reciprocating up and down. After that, the wedge-shaped fixing block 606 is pushed to perform horizontal reciprocating motion to consume energy, so that the placement plate 612 remains stable. Stable placement can reduce signal interference caused by PCB tilting and ensure the transmission quality of electronic signals in the laminated board. In the laminated board, each layer of PCB is electrically connected through metallized holes (blind holes, buried holes). Stable placement helps to ensure uniform contact resistance of these connection points and improve electrical performance. Interference between PCB layers is one of the important factors affecting circuit performance. Stable placement can reduce inter-layer interference and improve the anti-interference ability of the circuit. The laminated board will be subjected to certain mechanical stresses during assembly and use. A stably placed PCB can better disperse these stresses and improve the mechanical strength and stability of the laminated board. During the assembly process, a stably placed PCB is easier to position and fix, thereby improving assembly efficiency and accuracy.

[0062] Since the height detector 611 is electrically connected to the controller, when the height detector 611 detects that the stacking height of the PCB board is too high, the electric telescopic rod 609 is controlled to retract, and the PCB board on the top surface of the placement plate 612 is clamped on four sides, and the telescopic frame 607 is controlled to extend through the controller to protect the PCB board inside the telescopic frame 607 to prevent it from shifting. The four-sided clamping can evenly apply pressure to prevent the PCB board from being deformed due to uneven external force during the processing, which is very important for maintaining the structural integrity and electrical performance of the PCB board. During the stacking process of the PCB board, the edge part is easily damaged. The four-sided clamping and the protection of the telescopic frame 607 can reduce the mechanical damage to the edge of the PCB board. Through the four-sided clamping, it can be ensured that the PCB board maintains the correct position and height during the stacking process, thereby improving the stacking accuracy and avoiding assembly problems caused by position shift.
