Description

Technical Field

[0001] This utility model relates to the technical field of PCB board processing, and in particular to a paper separator supply device and a PCB sorting and packaging system. Background Technology

[0002] In the PCB sorting and assembly industry, due to the presence of circuitry, gold plating, and electronic components on the surface of PCBs, it's common practice to add separator paper between PCBs during stacking, transportation, and storage to prevent short circuits and other performance issues caused by scratches and collisions between adjacent products. Because PCBs have varying gold plating materials and scratch resistance requirements, a wide variety of separator papers are needed, including sulfur-free paper, dust-free paper, PVC paper (oil paper), and white kraft paper. Separators create clear separation between circuit boards, facilitating easy separation during subsequent use or processing, reducing adhesion and accidental removal, and improving operational efficiency. Furthermore, they block moisture and dust from the air, reducing their corrosive effects on the circuit boards, extending their lifespan, and ensuring stability during storage and transportation. For thinner products, bakelite support boards are added to the top and bottom of the stacked products to prevent damage during packaging and transportation. Therefore, the existing PCB sorting process requires a continuous supply of separator paper and bakelite boards.

[0003] However, during the PCB packaging process, automated handling of separators presents several challenges, including static electricity causing separators to attract each other, material properties leading to slippage, adhesion resulting in multiple separators being removed, and misalignment making gripping difficult. These issues negatively impact handling efficiency and consequently, overall work efficiency. Similarly, automated handling of bakelite boards presents challenges due to their smooth surfaces, negative pressure adhesion during separation, difficulty in separating them by pulling, and the intertwining and adhesion of burrs from cut edges between adjacent boards. Therefore, a separator / partition supply device is needed to continuously and stably provide single sheets of separators and single sheets of bakelite boards. Utility Model Content

[0009] Furthermore, there are two paper feeding friction toothed belts and two reverse rollers.

[0011] And / or, the second conveying assembly further includes a second end sensor, which is connected to the second baffle and is positioned toward the second conveyor belt.

[0012] Furthermore, the feeding module also includes a pressure roller, which is connected to the second body and located on the side of the roller close to the second conveying component.

[0013] Furthermore, a movable baffle is movably connected to one side of the second conveyor belt, and a fixed baffle is connected to the other side.

[0014] Furthermore, the feeding module also includes two support blocks, a connecting shaft, and a movable block.

[0018] The technical solutions provided in this application have the following advantages compared with the prior art:

[0019] In this application, the paper separator supply device is divided into two parts: a paper conveying mechanism and a bakelite board conveying mechanism.

The paper separation component includes a first driving component and a conveying module. The conveying module includes a paper feeding friction toothed belt and a reverse wheel. The paper feeding friction toothed belt can apply friction to the lower layer of paper in contact with it, causing the lower layer of paper to leave the paper stack and be sent out. The reverse wheel can block the upper layer of paper behind the reverse wheel, ensuring that the bottom layer of paper is sent out one sheet at a time, thereby achieving the effect of single-sheet paper separation and material picking. After the paper separation component takes out the single sheet of paper, it is conveyed to the first conveying component and then conveyed to the first baffle via the first conveyor belt.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Therefore, they should not be construed as limitations on this invention.

[0033] like Figure 1 - Figure 5As shown, the present application provides a paper separator supply device 1, comprising:

[0034] The paper conveying mechanism 10 includes a first body 11, a paper separation component 13, and a first conveying component 15. The paper separation component 13 and the first conveying component 15 are disposed on the first body 11. The paper separation component 13 includes a first driving member 131 and a conveying module 133. The first driving member 131 drives and connects to the conveying module 133. The conveying module 133 includes a paper feeding friction toothed belt 1331 and a reverse wheel 1332. The paper feeding friction toothed belt 1331 is disposed on the first body 11 and extends along the extension direction of the first body 11. The reverse wheel 1332 is disposed above the paper feeding friction toothed belt 1331. The first conveying component 15 includes a first conveyor belt 151 and a first baffle 153. One end of the first conveyor belt 151 is connected to the conveying module 133, and the first baffle 153 is connected to the other end of the first conveyor belt 151.

[0035] The phenolic resin board conveying mechanism 30 includes a second main body 31, a phenolic resin board separation component 33, and a second conveying component 35. The phenolic resin board separation component 33 and the second conveying component 35 are disposed on the second main body 31. The phenolic resin board separation component 33 includes a lifting module 331 and a board feeding module 333. The lifting module 331 includes a second driving member 3311 and a pallet 3313. The second driving member 3311 drives the pallet 3313 to move vertically. The board feeding module 333 is located on one side of the lifting module 331. The board feeding module 333 includes a third driving member 3331 and a roller 3333. The third driving member 3331 drives the roller 3333 to roll. The second conveying component 35 includes a second conveyor belt 351 and a second baffle 353. One end of the second conveyor belt 351 is connected to the board feeding module 333, and the second baffle 353 is connected to the other end of the second conveyor belt 351.

[0036] Through the innovative combination of the paper feeding friction belt 1331 and the reverse roller 1332, the paper feeding friction belt 1331 acts on the bottom layer of paper with directional friction force, separating it from the upper layer of paper using the principle of "friction difference". Meanwhile, the reverse roller 1332 prevents the upper layer of paper from moving forward by rotating in the opposite direction, forming a precise separation effect of "bottom layer fed out, top layer retained". This design completely solves the problem of multiple sheets being linked together in the traditional paper picking method due to static electricity or material characteristics (such as the stickiness of sulfur-free paper), and improves the success rate of single sheet paper output.

[0037] To address the issues of negative pressure adsorption and intertwined burrs during cutting caused by the smooth surface of bakelite boards, a combined solution of "lifting pallet 3313 + rolling roller 3333" is adopted. After the bakelite boards are manually stacked on pallet 3313, the second drive component 3311 drives pallet 3313 to gradually rise, bringing the top layer of bakelite boards into contact with the roller 3333. The roller 3333 then uses the friction generated by the rotation of the third drive component 3331 to individually pull the boards out. This method avoids damage to the boards caused by the traditional "hard pulling" method, and by using rolling friction instead of sliding friction, it significantly reduces separation resistance, achieving stable single-sheet output even for bakelite boards with severe burrs.

[0038] The paper separator and bakelite board conveying mechanism 30 work independently yet collaboratively, providing two types of materials to the PCB sorting equipment simultaneously. For example, in thin PCB stacking scenarios, the dual feeding of "paper separator laying + bakelite board support" can be completed simultaneously, improving efficiency and significantly reducing equipment downtime compared to the traditional staged feeding mode.

[0039] The first main body 11 serves as the basic frame of the paper conveying mechanism 10. It is usually made of metal profiles (such as aluminum profiles or steel structures) welded or bolted together, and provides the mounting reference for the paper separation assembly 13 and the first conveying assembly 15.

[0040] The first driving component 131 is typically a servo motor or a stepper motor, which is connected to the conveying module 133 via a transmission mechanism such as a synchronous belt and a gearbox. It provides a power source to drive the paper feeding friction belt 1331 and the reverse wheel 1332 to rotate at a set speed. The speed is adjusted by the control system to adapt to the separation requirements of different paper materials (e.g., oiled paper requires a low speed to increase friction, while dust-free paper requires a high speed to reduce electrostatic adsorption).

[0041] The paper feeding friction belt 1331 has fine teeth on its surface and is made of wear-resistant rubber or polyurethane, extending along the length of the first main body 11. The reverse roller 1332 is covered with a high-friction coefficient material (such as silicone) and is located directly above the toothed belt. The distance between the roller and the toothed belt can be adaptively adjusted by a spring mechanism.

[0042] Single-sheet separation principle: When multiple layers of separators are stacked above the toothed belt, the first driving component 131 drives the toothed belt forward, and the bottom layer of separators moves with the toothed belt due to friction. The reverse wheel 1332 rotates in the opposite direction, applying a backward frictional force to the upper layer of separators, preventing them from following, thus achieving single-sheet separation. This requires that the difference in friction between the toothed belt and the reverse wheel 1332 be greater than the adhesive force between the separators. Forced separation through mechanical friction eliminates the need for an additional anti-static device, reducing costs and effectively solving the problem of electrostatic adsorption of separators. The blocking effect of the reverse wheel 1332 prevents the upper layer of separators from following the bottom layer, solving the problem of multiple sheets being picked up in small increments.

[0043] The first conveyor belt 151 is a circular belt made of PVC or PU material, with a width matching the separator paper (usually 20-50mm wider than the separator paper), and a linear speed consistent with the paper feeding friction belt 1331 (error ≤ ±2%). The first baffle 153 is set perpendicular to the conveyor belt's running direction, made of acrylic or metal, with rounded edges to prevent scratching the separator paper. The conveyor belt smoothly transports the separated individual separator papers from the conveyor module 133 to the end, and the surface anti-slip texture (such as herringbone pattern) ensures no slippage during the transmission process. The baffle serves as a positioning reference for the separator paper; when the separator paper touches the baffle, it stops moving forward, forming a neat stacked queue, facilitating vacuum suction by the robotic arm.

[0044] The second main body 31 is arranged side by side with the first main body 11, using the same material and modular design. Its height is slightly higher than the paper conveying mechanism 10, facilitating the layered stacking of the bakelite boards and the paper separator. The second main body 31 supports the bakelite board separation assembly 33 and the second conveying assembly 35, ensuring the vertical alignment accuracy between the rollers 3333 and the pallet 3313. An integrated waste collection trough collects debris falling during bakelite board separation, keeping the equipment clean.

[0045] The second driving component 3311 is typically a cylinder or an electric push rod. The pallet 3313 is a rectangular flat plate with anti-slip texture on the surface. It is 20-30mm larger than the bakelite board and has edge guards (10-15mm high) to prevent the boards from slipping. The operation process is as follows: the bakelite boards are manually stacked on the pallet 3313. The second driving component 3311 drives the pallet 3313 to rise, so that the top layer of bakelite boards contacts the rollers 3333. When the bakelite boards are separated, the pallet 3313 automatically replenishes and rises, keeping the rollers 3333 in contact with the top layer of boards to achieve continuous feeding.

[0046] The third driving component 3331 is similar to the first driving component 131, and is driven by a motor. The roller 3333 moves the uppermost bakelite board forward through rotational friction, achieving single-sheet separation by utilizing the frictional difference between the boards (the frictional force of the roller 3333 is greater than the adhesive force between the boards). For boards with burrs adhering to them, the knurling structure can be embedded in the gaps between the burrs for forced separation. Regarding the negative pressure adsorption problem: the rolling friction of the roller 3333 replaces the traditional "hard pulling," avoiding board deformation caused by negative pressure. The mechanical meshing of the knurling structure effectively breaks down the burr connections, solving the problem of burr intertwining.

[0047] The second conveyor belt 351 uses a heavy-duty rubber belt. The second baffle 353 has a similar structure to the first baffle 153, but with added elastic buffer pads to prevent the bakelite board from being damaged by impact.

[0048] The paper separator and bakelite board conveying mechanism 30 can be started and stopped independently. Different feeding rhythms can be set through the control system to adapt to different PCB stacking process requirements.

[0049] The first main body 11 and the second main body 31 are arranged in an L-shape or in parallel, with the paper-separated outlet and the bakelite board outlet intersecting perpendicularly, which facilitates the subsequent robotic arm to simultaneously grasp the two materials and shorten the material handling path.

[0050] The toothed belt and reverse roller 1332 of the paper conveying mechanism 10 can be quickly replaced to adapt to paper with different friction coefficients; the bakelite board roller 3333 offers a variety of knurling specifications and can be changed with tools to adapt to boards with different degrees of burrs.

[0051] Furthermore, such as Figure 2 As shown, the conveying module 133 also includes an acceleration wheel 1333, a guide wheel 1334 and a plurality of auxiliary wheels 1335. The acceleration wheel 1333 and the guide wheel 1334 are arranged in sequence in the forward direction of the paper feeding friction toothed belt 1331. The auxiliary wheels 1335 are located on the first main body 11, and the acceleration wheel 1333 and the guide wheel 1334 are each arranged above an auxiliary wheel 1335.

[0052] The acceleration wheel 1333 is located at the front end of the paper feeding friction toothed belt 1331. It applies an additional thrust to the paper separator by a linear speed higher than that of the toothed belt, ensuring that the paper separator passes through the separation area quickly and avoiding subsequent paper separators from sticking together due to slow speed. The guide wheel 1334 adopts a conical design, which corrects the offset trajectory in real time during the paper separator conveying process, significantly improving the positioning accuracy of the subsequent gripping mechanism.

[0053] Multiple auxiliary wheels 1335 are evenly distributed on the first main body 11, forming an "upper and lower clamping" structure with the acceleration wheel 1333 and guide wheel 1334 above, effectively suppressing the sagging deformation of the paper feeding friction toothed belt 1331 during high-speed operation. Tests have shown that adding auxiliary wheels 1335 reduces the amplitude of the toothed belt, enabling stable feeding of ultra-thin paper (such as dust-free paper) and avoiding paper tearing caused by toothed belt vibration.

[0054] Furthermore, there are two paper feeding friction toothed belts 1331 and two reverse rollers 1332. The two paper feeding friction toothed belts 1331 are arranged at intervals along a direction perpendicular to their extension direction, and the two reverse rollers 1332 are respectively arranged parallel to the two paper feeding friction toothed belts 1331.

[0055] The dual-sided toothed belts provide friction simultaneously, achieving a more uniform separation force for wide or heavily adhered separators (such as sulfur-free separators and oiled paper), avoiding tearing caused by unilateral force. Furthermore, the dual reverse rollers 1332 symmetrically block the upper separator, balancing the force on both sides and preventing skewing during separation, ensuring accurate single-sheet output.

[0056] Furthermore, the first conveying assembly 15 also includes a first end sensor 155, which is connected to the first baffle 153 and is positioned toward the first conveyor belt 151;

[0057] And / or, the second conveying assembly 35 further includes a second end sensor 355, which is connected to the second baffle 353 and is positioned toward the second conveyor belt 351.

[0058] The first end sensor 155 detects whether the paper separator has been conveyed to the first baffle 153, and the second end sensor 355 detects whether the bakelite board is in place, preventing equipment shutdown due to empty or leaking materials. The sensor signals can be linked to the control system; if the material is not in place, an alarm will be triggered or the gripping action will be paused, reducing manual inspection costs and lowering the risk of misoperation.

[0059] The first end sensor 155 (such as an infrared photocell) detects in real time whether the paper separator has reached the first baffle 153. When the paper separator is detected to be in place, a signal is sent to the control system to trigger the gripping action. If no material is detected within the set time, an audible and visual alarm is immediately issued and the equipment is paused to avoid process interruption caused by the robotic arm grabbing empty.

[0060] In scenarios where both separator paper and bakelite board conveying are used simultaneously, the second end sensor 355 can synchronously monitor the arrival status of the bakelite board and realize the linkage triggering of "dual material readiness" through the control system. For example, in the PCB stacking process, the stacking robot arm is only allowed to move when both separator paper and bakelite board are in place, avoiding stacking sequence errors caused by material delays on one side and improving process accuracy.

[0061] Furthermore, the feeding module 333 also includes a pressure roller 3335, which is connected to the second body 31 and located on the side of the roller 3333 close to the second conveying assembly 35.

[0062] The pressure roller 3335 works in conjunction with the roller 3333 to apply downward pressure when the bakelite board detaches from the stack, counteracting slippage caused by the smooth surface and ensuring that only the top layer of bakelite board is conveyed. Furthermore, the pressing action of the pressure roller 3335 prevents the lower layer of bakelite board from contacting the roller 3333, resolving the issue of multiple sheets separating due to slight adhesion caused by cutting burrs.

[0063] The pressure roller 3335, made of an elastic material (such as rubber), applies constant pressure to the surface of the bakelite board. When the roller 3333 moves the top bakelite board, a "clamping gap" is formed between the pressure roller 3335 and the roller 3333, allowing only a single board to pass through. Furthermore, the linear velocity matching design between the pressure roller 3335 and the roller 3333 (the pressure roller 3335 is 5% slower than the roller 3333) applies slight braking the moment the bakelite board detaches from the stack, preventing the board from slipping off the conveyor belt edge due to inertia.

[0064] Furthermore, a movable baffle 356 is movably connected to one side of the second conveyor belt 351, and a fixed baffle 357 is connected to the other side. The movable baffle 356 and the fixed baffle 357 are located on opposite sides of the second conveyor belt 351 and form a passage space. The movable baffle 356 can reciprocate in a direction perpendicular to the second conveyor belt 351.

[0065] The adjustable spacing of the 356 movable baffles accommodates bakelite boards of varying widths (such as thin and standard boards), preventing material jamming or misalignment caused by fixed baffle spacing. The two side baffles create a narrow passageway, restricting lateral movement of the bakelite boards and ensuring they are conveyed along the conveyor belt's centerline for precise gripping by the subsequent robotic arm.

[0066] Furthermore, such as Figure 3 , Figure 4 As shown, the feeding module 333 also includes two support blocks 3336, a connecting shaft 3337, and a movable block 3338. The two support blocks 3336 are respectively connected to the two sides of the second main body 31. The two ends of the connecting shaft 3337 are respectively connected to the two support blocks 3336. The movable block 3338 is movably connected to the connecting shaft 3337. One end of the movable baffle 356 is connected to the movable block 3338, and the other end extends to the second conveyor belt 351.

[0067] The linear sliding of the movable baffle 356 is achieved through the combination of support block 3336, connecting shaft 3337, and movable block 3338, eliminating the need for complex drive devices and reducing manufacturing costs and maintenance difficulty. The movable block 3338 can be manually or electrically driven to move along the connecting shaft 3337, allowing for baffle spacing adjustments to be completed within seconds, thus improving equipment changeover efficiency.

[0068] Furthermore, the lifting module 331 also includes a positioning baffle 3315, which is connected to the second body 31 and located on one side of the support plate 3313. The lifting module 331 also includes a stop bar 3316, which is movably connected to the second body 31 and located on the other side of the support plate 3313. The positioning baffle 3315 and the stop bar 3316 are correspondingly arranged on both sides of the support plate 3313, forming an upper plate space.

[0069] Positioning baffles 3315 and baffles 3316 define the placement area of ​​the bakelite board stack, preventing separation difficulties or equipment jamming caused by manual misalignment. Clear positioning boundaries shorten manual alignment time, making it particularly suitable for batch loading scenarios and reducing downtime.

[0070] Furthermore, the lifting module 331 also includes a limiting block 3317, which is movably connected to the second body 31 and located on the side of the pallet 3313 away from the feeding module 333. The limiting block 3317, the positioning baffle 3315, and the stop bar 3316 together form an upper plate space.

[0071] The positioning baffle 3315 (front), the stop bar 3316 (rear), and the limiting block 3317 (side) form a closed space, ensuring that the bakelite boards stacked on the pallet 3313 are constrained in the X / Y / Z axes, preventing separation failure due to shaking during transportation. The limiting block 3317 blocks the bakelite boards on the rear side of the pallet 3313, especially during the lifting and lowering of the pallet 3313, preventing the stacked materials from sliding backward due to inertia, thus improving safety.

[0072] This utility model also proposes a PCB sorting and packaging system, which includes a paper separator supply device 1. The specific structure of the paper separator supply device 1 is as described in the above embodiments. Since this PCB sorting and packaging system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0073] A stable supply of separator paper and bakelite board can seamlessly integrate with PCB stacking, visual inspection, packaging and other processes to form a continuous automated production line and reduce manual intervention points.

[0074] Furthermore, as the core module of the system, its reliability directly improves the overall capacity of the sorting and packaging system, avoids production line downtime due to material supply failures, and reduces overall costs.
