Description

Technical Field

[0001] This invention relates to the field of desoldering technology for electronic components, specifically to an auxiliary stripping device for electronic components. Background Technology

[0002] As is well known, detinning is a process that removes tin plating or tin alloys from the surface of a metal substrate or separates and recovers tin from waste through chemical, electrolytic or physical thermal means. It is widely used in scenarios such as electronic rework, scrap metal recycling, and treatment of defective electroplated products, especially when recycling or reworking circuit boards, where components need to be peeled off the surface of the circuit board.

[0003] The problems with existing technologies are as follows: The most commonly used drum-type desoldering technology involves crushing waste circuit boards and placing them into a high-temperature drum. The components are separated from the solder by the rotation of the drum, the high temperature of the molten solder, and mechanical friction. This technology is suitable for large-scale waste circuit board recycling scenarios, but it has the problems of weak targeting and high damage rate. It is difficult to carry out high-quality recycling scenarios for precision component repair and targeted disassembly. At the same time, the uneven heating at the soldering position may lead to incomplete component removal, making it inconvenient to use.

[0004] Based on the above-mentioned situation, we found that the existing desoldering methods are difficult to avoid the above problems at the same time. Therefore, we propose an auxiliary desoldering device for electronic components that can perform desoldering on the surface of a single substrate, reduce uneven heating at the soldering position, minimize damage to the substrate and electronic components when peeling off electronic components, facilitate rework and reuse, and can perform desoldering on substrates of various shapes and sizes. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an auxiliary stripping device for electronic components. This device can perform desoldering on the surface of a single substrate, reduce uneven heating at the soldering point, minimize damage to the substrate and electronic components during the stripping process, facilitate rework and reuse, and can perform stripping on substrates of various shapes and sizes.

[0007] (II) Technical Solution

[0008] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an auxiliary stripping device for electronic components, comprising a frame and a main frame fixedly connected to the top of the frame, a slide table installed on the inner side of the frame, a fixed bracket provided on the top of the slide table, two pushing members fixedly connected to the left and right sides of the inner side of the fixed bracket, grippers fixedly connected to the right side of the left pushing member and the left side of the right pushing member, and a functional part provided at the bottom of the main frame;

[0009] The pushing component includes a push tube, a driven slider is slidably connected to the inner side of the push tube, a driven rod is slidably connected to the right side of the left push tube and the left side of the right push tube through a sealing component, a return spring is sleeved on the outer side of the driven rod, the two ends of the return spring are fixedly connected to the driven slider and the push tube respectively, and a U-shaped tube is fixedly connected to the end of the push tube away from the driven rod.

[0010] The pump device and the return box are fixedly connected to the inner side of the fixed bracket;

[0011] The gripper includes a gripper frame, an arc frame, a slide bar, a support spring, and a contact pad.

[0012] Using the above technical solution, a pusher and clamps are used to clamp and fix the substrate. In use, the substrate can be placed between the two pushers, and then water is added to the U-shaped tube. The water enters the inside of the push tube and pushes the driven slider. The driven rod connected to the driven slider extends from the inside of the push tube and fixes the substrate through the clamps. When the two clamps on the left and the two clamps on the right approach each other, they will conform to the surface shape of the substrate through the arc-shaped clamp and the contact pad. It can still stably fix irregular or round substrates. After fixing, the functional part at the bottom of the main frame can be controlled to descend vertically and its position can be adjusted in the horizontal direction. Then, the desoldering, desoldering and peeling actions are performed on the substrate surface.

[0013] The present invention is further configured such that: an electrically controlled valve is fixedly connected to the side of the front loop tube away from the push tube, a branch pipe is fixedly connected to the side of the electrically controlled valve away from the loop tube, the inlet end of the pump device is fixedly connected to the reflux box, and the outlet end of the pump device is fixedly connected to the branch pipe.

[0014] By adopting the above technical solution, a pump device can be set up to easily draw water from the return box and supply it to the branch pipe. The water then passes through the U-shaped pipe to push the driven slider to fix the base. During the process of pushing the driven slider, the return spring is compressed. After the operation is completed, the return spring pushes the driven slider and the driven rod to reset. After the electric control valve is opened, the water can flow back to the return box.

[0015] The present invention is further configured such that: a servo motor is installed on the right side of the platform, the output end of the servo motor is fixedly connected to an active frame, and the left and right sides of the active frame are fixedly connected to the U-shaped tube.

[0016] By adopting the above technical solution, and by setting a servo motor in conjunction with the active frame, the shaped tube, the entire pressing component, and the fixed bracket can be driven to flip after the desoldering action is completed, so as to flip the base.

[0017] The invention is further configured such that: the rear side of the front loop tube is connected to the rear loop tube, a turntable is fixedly connected to the left side of the frame, a rotating frame is rotatably connected to the right side of the turntable, and the right side of the rotating frame is fixedly connected to the left loop tube.

[0018] By adopting the above technical solution, a turntable is set up in conjunction with a rotating frame to support the left push tube on the inside of the frame. This allows the left loop tube, along with the entire pusher and the fixed bracket, to be supported when it is rotated under the drive of the servo motor and the active frame.

[0019] The present invention is further configured such that: a connecting frame is fixedly connected to the outer side of the slide table, the outer side of the connecting frame is fixedly connected to the table frame, and a soft pad is fixedly connected to the inner side of the slide table.

[0020] By adopting the above technical solution, a connecting frame is set up to assemble the slide table inside the frame, and soft pads are set up to prevent damage caused by falling when picking up stripped electronic components and falling substrates.

[0021] The present invention is further configured such that: the claw frame is fixedly connected to the driven rod on the side near the driven rod; the arc-shaped frame is located inside the claw frame; the slide rod is fixedly connected to the top and bottom of the arc-shaped frame; the support spring is sleeved on the outside of the slide rod; the two ends of the support spring are fixedly connected to the arc-shaped frame and the claw frame respectively; and the contact pad is fixedly connected to the inside of the arc-shaped frame.

[0022] By adopting the above technical solution, an arc-shaped frame is set up to directly contact the outer edge of the substrate with the contact pad. At the same time, when fixing the substrate, the arc-shaped frame will slide to the bottom of the arc due to its own shape, so as to fix it stably. The support spring and the sliding rod install the arc-shaped frame on the inner side of the claw frame, and allow a certain amount of shaking space. When the soldering iron device and the desoldering device press down to remove and absorb solder, it is avoided that excessive pressure will be applied, which may damage the substrate.

[0023] The present invention is further configured such that: an extension plate is fixedly connected to the bottom of the front claw frame, a reduction motor is fixedly connected to the top of the extension plate, and a mating frame is fixedly connected to the output end of the reduction motor;

[0024] Connecting plates are fixedly connected to the rear side of the top of the left claw frame and the front side of the top of the right claw frame. End rods are slidably connected to the inner side of the connecting plates. Baffles are fixedly connected to the rear side of the left end rod and the front side of the right end rod. Fastening bolts are threadedly connected to the inner side of the connecting plates. The fastening bolts are in contact with the end rods on the side closest to the end rods.

[0025] Using the above technical solution, a reduction motor is installed by setting an extension plate. After the desoldering and desoldering actions are completed and the substrate is flipped, the reduction motor is started. At this time, the mating frame repeatedly strikes the arc frame to drive the clamped substrate to vibrate, which helps to shake off the electronic components that have not been peeled off after desoldering. At the same time, residual impurities are also shaken off. The baffle connected by the connecting piece and the end rod can block the front and rear sides of the substrate to prevent the substrate from loosening due to radial displacement. After sliding the end rod and the baffle along the connecting piece to the appropriate substrate limit position, the fastening bolt can be tightened to complete the pressure fixation of the end rod position.

[0026] The present invention is further configured such that: the functional part includes an upper suspension, an electric soldering iron device is fixedly connected to the inner side of the upper suspension, a suction frame is installed on the right side of the upper suspension, a first electric cylinder is fixedly connected to the top of the suction frame, and the telescopic end of the first electric cylinder passes through the suction frame and is fixedly connected to a desoldering device.

[0027] Using the above technical solution, an upper suspension is set up to install an electric soldering iron device for melting the solder joint. Then, the first electric cylinder extends to push the desoldering device to the melting position to perform a desoldering action.

[0028] The present invention is further configured such that: a second electric cylinder is rotatably connected to the rear side of the top of the upper suspension, and a shovel frame is rotatably connected to the telescopic end of the second electric cylinder; the front side of the shovel frame is rotatably connected to the rear side of the upper suspension.

[0029] A horizontal guide rail is fixedly connected to the bottom of the main frame. A vertical guide rail is provided at the bottom of the horizontal guide rail. Electric sliders are movably connected to the outer sides of both the horizontal and vertical guide rails. The bottom of the top electric slider is fixedly connected to the vertical guide rail. A sub-frame is fixedly connected to the bottom of the bottom electric slider. A servo motor is fixedly connected to the bottom of the sub-frame. A lead screw is fixedly connected to the output end of the servo motor. A transmission block is threadedly connected to the outer side of the lead screw. The right side of the transmission block is fixedly connected to the left side of the upper suspension.

[0030] Using the above technical solution, by setting up a scraper, after completing the desoldering and desoldering actions, the second electric cylinder can push the scraper to rotate along the upper suspension to the scraping position located at the bottom of the soldering iron device. Then, the desoldered electronic components can be scraped off along the top of the substrate. The set horizontal guide rail, together with the top electric slider, is used to drive the entire vertical guide rail and the bottom structure to move laterally. The bottom electric slider drives the bottom sub-frame to move longitudinally, so as to adjust the horizontal position of the functional part. When the servo motor drives the screw to rotate forward or backward, the functional part will rise and fall vertically to move closer to or away from the substrate.

[0031] The present invention is further configured such that: a limiting rod is fixedly connected to the bottom of the sub-frame, the outer side of the limiting rod is slidably connected to the upper suspension, the front and rear sides of the bottom of the main frame are fixedly connected to limiting guide rails, a support block is slidably connected to the inner side of the limiting guide rail, and the bottom of the support block is fixedly connected to the longitudinal guide rail.

[0032] By adopting the above technical solution, by setting a limit rod, the upper suspension can maintain stable vertical lifting and lowering under the limit of the limit rod when the transmission block is driven by the lead screw. The set limit guide rail is used to assist in supporting the movement of the longitudinal guide rail.

[0033] (III) Beneficial Effects

[0034] Compared with the prior art, the present invention provides an auxiliary stripping device for electronic components, which has the following beneficial effects:

[0035] This auxiliary stripping device for electronic components uses pushers and grippers to hold and fix the substrate. In use, the substrate is placed between the two pushers, and water is added to the U-shaped tube. The water enters the inside of the pusher tube and pushes the driven slider. The driven rod connected to the driven slider extends from the inside of the pusher tube and fixes the substrate through the grippers. When the two grippers on the left and two grippers on the right come close to each other, they conform to the surface shape of the substrate through the arc-shaped clamp and contact pad. It can still stably fix irregular or round substrates. After fixing, the functional part at the bottom of the main frame can be controlled to descend vertically and its position can be adjusted in the horizontal direction. Then, the desoldering, desoldering and stripping actions are performed on the substrate surface. Attached Figure Description

When the two clamps 6 on the left and the two clamps 6 on the right approach each other, they will conform to the surface shape of the substrate by the arc clamp and the contact pad 65. It can still fix the irregular or round substrate stably. After fixing, the functional part 7 at the bottom of the main frame 2 can be controlled to descend vertically and adjust its position in the horizontal direction. Then, the desoldering, desoldering and peeling actions are performed on the substrate surface.

[0052] Among them, an electric control valve 11 is fixedly connected to the side of the front loop tube 55 away from the push tube 51, and a branch pipe 10 is fixedly connected to the side of the electric control valve 11 away from the loop tube 55. The inlet end of the pump device 8 is fixedly connected to the return box 9, and the outlet end of the pump device 8 is fixedly connected to the branch pipe 10. By setting the pump device 8, water can be easily drawn from the return box 9 and supplied to the branch pipe 10. Then, the water passes through the loop tube 55 to push the driven slider 52 to fix the base. During the pushing process of the driven slider 52, the return spring 54 is compressed. After the operation is completed, the return spring 54 pushes the driven slider 52 and the driven rod 53 to reset.

A connecting frame 16 is fixedly connected to the outer side of the slide table 3, and the outer side of the connecting frame 16 is fixedly connected to the platform 1. A soft pad is fixedly connected to the inner side of the slide table 3. By setting the connecting frame 16, the slide table 3 is assembled on the inner side of the platform 1. By setting the soft pad, damage caused by falling can be avoided when picking up stripped electronic components and falling substrates. The claw frame 61 is fixedly connected to the driven rod 53 on the side near the driven rod 53. The arc frame 62 is located on the inner side of the claw frame 61. The slide rod 63 is fixedly connected to the top and bottom of the arc frame 62. The support spring 64 is sleeved on the outer side of the slide rod 63. The two ends of the support spring 64 are respectively connected to the arc frame 62 and the... The claw frame 61 is fixedly connected, and the contact pad 65 is fixedly connected to the inner side of the arc frame 62. The arc frame 62 and the contact pad 65 are set to directly contact the outer edge of the substrate. At the same time, when the arc frame 62 is fixed to the substrate, it will slide to the bottom of the arc due to its own shape to fix it stably. The support spring 64 and the slide rod 63 install the arc frame 62 on the inner side of the claw frame 61 and allow a certain amount of shaking space. When the soldering iron device 72 and the desoldering device 75 press down to remove and absorb solder, it is to avoid applying too much pressure and damaging the substrate. The bottom of the front claw frame 61 is fixedly connected to the extension plate 17, the top of the extension plate 17 is fixedly connected to the reduction motor 18, and the output end of the reduction motor 18 is fixedly connected to the mating frame 19.A connecting plate 31 is fixedly connected to the rear side of the top of the left claw frame 61 and the front side of the top of the right claw frame 61. An end rod 32 is slidably connected to the inner side of the connecting plate 31. A baffle 33 is fixedly connected to the rear side of the left end rod 32 and the front side of the right end rod 32.

[0054] Working principle of this embodiment: Pump device 8 draws water from return tank 9, and delivers it to the return tube 55 of pusher 5 through branch pipe 10 and solenoid valve 11. After the water enters the push tube 51, it pushes the driven slider 52, causing the driven rod 53 to extend outward. The gripper 6 at the end of the driven rod 53 then moves towards the center. The arc frame 62 on the inner side of the gripper frame 61 adaptively conforms to the shape of the substrate with the cooperation of support spring 64 and slider 63. The contact pad 65 directly contacts the outer edge of the substrate to achieve stable clamping of substrates of different shapes. At the same time, the end rod 32 in the sliding connecting piece 31 adjusts the position of the baffle 33. Tightening the fastening bolt 34 locks the substrate to prevent radial loosening. During the clamping process, the return spring 54 is compressed. After the desoldering operation is completed, the servo... The servo motor 14 drives the active frame 15 to rotate, causing the right-side loop tube 55 and the entire pushing component 5 and fixed bracket 4 to flip. The turntable 12 and the rotating frame 13 on the left side of the platform 1 support and guide the left-side loop tube 55, ensuring that the base body flips smoothly to adjust the angle. After the base body flips, the reduction motor 18 on the extension plate 17 starts, driving the mating frame 19 to strike the arc frame 62 to make the base body vibrate and shake off the components that are not completely peeled off and the residual impurities. After the operation is completed, the electric control valve 11 opens, and the water in the push tube 51 flows back to the return box 9. The return spring 54 rebounds and pushes the driven slider 52 and the driven rod 53 to reset. The gripper 6 releases the base body, and the peeled components and base body fall onto the padded slide 3 to avoid falling and damage.

The horizontal guide rail 22, together with the top electric slider 24, is used to drive the entire vertical guide rail 23 and the bottom structure to move laterally. The bottom electric slider 24 drives the bottom sub-frame 25 to move longitudinally, so as to adjust the horizontal position of the functional unit 7. When the servo motor 26 drives the lead screw 27 to rotate forward or backward, the functional unit 7 will rise and fall vertically to move closer to or away from the substrate. The bottom of the sub-frame 25 is fixedly connected to the limit rod 29. The outer side of the limit rod 29 is slidably connected to the upper suspension 71. The front and rear sides of the bottom of the main frame 2 are fixedly connected to the limit guide rail 30. The inner side of the limit guide rail 30 is slidably connected to the support block. The bottom of the support block is fixedly connected to the vertical guide rail 23. By setting the limit rod 29, when the upper suspension 71 is driven by the lead screw 27 because the transmission block 28 is driven by the limit rod 29, it can maintain stable vertical rise and fall under the limit of the limit rod 29. The limit guide rail 30 is used to assist in supporting the movement of the vertical guide rail 23.

[0058] The working principle of this embodiment is as follows: The upper suspension 71 of the functional unit 7 is used to install the soldering iron device 72. The suction rack 73 on its right side is driven by the first electric cylinder 74 to raise and lower the desoldering device 75. During operation, the soldering iron device 72 first melts the solder joints of the substrate, and then the first electric cylinder 74 pushes the desoldering device 75 to the melting position to complete the desoldering. The rear side of the upper suspension 71 is connected to the scraper 21 through the second electric cylinder 20. After the desoldering is completed, the second electric cylinder 20 can push the scraper 21 to rotate around the upper suspension 71 to a suitable position to remove the desoldering material. The electronic components are soldered; the horizontal guide rail 22 and the vertical guide rail 23 at the bottom of the main frame 2 cooperate with the electric slider 24 to achieve precise horizontal and vertical positioning of the functional part 7. The servo motor 26 on the sub-frame 25 drives the lead screw 27 to rotate, which drives the upper suspension 71 to rise and fall vertically through the transmission block 28, so that the functional part 7 moves closer to or away from the base. The limiting rod 29 of the sub-frame 25 can ensure the stability of the vertical rise and fall of the upper suspension 71. The limiting guide rail 30 of the main frame 2 assists in supporting the vertical guide rail 23 to ensure its smooth movement.
