Description

Technical Field

[0001] This utility model belongs to the technical field of adhesive removal equipment, and in particular relates to a pad flipping adhesive removal machine. Background Technology

[0002] In the manufacturing process of printed circuit boards (PCBs), backing plates are important auxiliary materials used to support and protect the PCB. Specifically, during PCB processing, aluminum sheets are typically attached to the front side, while the backing plate is used to secure it to the back. The connection between the backing plate and the PCB is usually achieved by applying adhesive to the surrounding edges. While this method ensures the stability of the PCB during processing, adhesive residue often prevents the backing plate from being reused when it is subsequently removed.

[0003] Currently, the removal of pads mainly relies on manual or simple mechanical peeling methods. However, due to the strong adhesive properties and the fact that it usually adheres to the narrow areas around the edges of the pads, manual peeling is not only inefficient, but the residual adhesive also reduces the flatness and surface quality of the pads, making them unsuitable for reuse. This increases production costs and reduces recycling efficiency. Utility Model Content

[0038] In one embodiment of this utility model, such as Figure 1As shown, a pad flipping and adhesive removal machine is provided for removing adhesive from the edges of pads. It includes a frame 100, a pad feeding mechanism 200, a front adhesive grinding mechanism 300, a rear adhesive grinding mechanism 400, a flipping mechanism 500, and a pad collection mechanism 600. A transmission mechanism 110 is provided above the frame 100. The pad feeding mechanism 200 is located on one side of the frame 100. Two sets of front adhesive grinding mechanisms 300 are provided and installed on the longitudinal sides of the frame 100 respectively. The front adhesive grinding mechanism 300 includes a grinding assembly 310, a belt drive assembly 320, and a pressing assembly 330. The belt drive assembly 320 is movably mounted on the frame 100, and the pressing assembly 330 is located above the belt drive assembly 320; the two work together to smoothly transport the pad forward. The grinding assembly 310 is located between the belt drive assemblies 320 to remove adhesive from the edges of the pad. The rear gluing mechanism 400 is identical to the front gluing mechanism 300 and is connected to the rear side of the front gluing mechanism 300. The flipping mechanism 500 is disposed between the front gluing mechanism 300 and the rear gluing mechanism 400. The plate-collecting mechanism 600 is connected to the rear side of the rear gluing mechanism 400.

[0039] Specifically, the pad is automatically fed into the frame 100 by the plate feeding mechanism 200 and guided to the front gluing mechanism 300 by the transmission mechanism 110. The belt drive assembly 320 of the front gluing mechanism 300 cooperates with the extrusion assembly 330 to clamp the pad and transport it smoothly; at the same time, the grinding assembly 310 grinds and removes the adhesive on the edge of the pad. Initially, the front gluing mechanism 300 grinds both sides of the pad in the length direction. After being automatically rotated 90° by the flipping mechanism 500, the rear gluing mechanism 400 then grinds both sides of the pad in the width direction. The pad with double-sided adhesive removal is automatically collected by the plate collecting mechanism 600, realizing continuous production.

[0040] Furthermore, such as Figure 2 As shown, a substrate A340 is disposed on one side of the frame 100, and a set of front abrasive mechanisms 300 is provided on substrate A340; the extrusion assembly 330 includes a fixed plate 331, a spring stop 332, a pressure roller 333, and a rocker arm 334. The fixed plate 331 is disposed on the side near substrate A340. The inner side of the fixed plate 331 is connected to the fixed spring stop 332 and the rotatable rocker arm 334. The rocker arm 334 and the spring stop 332 are connected by a spring; the lower side of the rocker arm 334 is connected to the pressure roller 333, and the lower side of the pressure roller 333 is provided with a belt drive assembly 320. Specifically, the pad enters the belt drive assembly 320, the central shaft of the pressure roller 333 is connected to the movable rocker arm 334, the pad extends between the belt drive assembly 320 and the pressure roller 333, the pressure roller 333 is slightly lifted upward by a reverse force, but under the elastic force of the spring, it always maintains a downward driving force to adaptively press the pad and ensure smooth transportation.

[0041] Furthermore, such as Figure 2As shown, the grinding assembly 310 includes a grinding motor 311 and a milling cutter 312. The grinding motor 311 is mounted on the substrate A340, and the milling cutter 312 is connected to the grinding motor 311. The milling cutter 312 is disposed within the belt drive assembly 320, and its vertical position is flush with the drive end of the belt drive assembly 320. The grinding motor 311 drives the milling cutter 312 to rotate at high speed, improving the adhesive removal efficiency.

[0042] Furthermore, such as Figure 3 As shown, the front abrasive mechanism 300 also includes a substrate B350, which is disposed on the other side of the substrate A340. A parallel drive assembly 370 is disposed below the substrate B350, and the drive end of the parallel drive assembly 370 is connected to the substrate B350 to drive the substrate B350 to move towards or away from the substrate A340. A translation base plate 360 ​​is disposed on the frame 100, and a translation drive assembly 370 is disposed on the upper side of the translation base plate 360, including a translation motor 371, a translation lead screw 372, and a translation seat 373. The translation motor 371 is mounted on the translation base plate 360, and its drive end is connected to one end of the translation lead screw 372, while the other end is rotatably connected to the translation seat 373. A translation nut seat 374 is disposed on the translation lead screw 372, and the substrate B350 is disposed on its upper end. Under the drive of the translation motor 371, the substrate B350 moves towards or away from the substrate A340. The translation drive assembly 370 can adjust the spacing to fit the length or width of the pad before locking the position.

[0043] Furthermore, such as Figure 4 As shown, the flipping mechanism 500 includes a corner bracket 510, a corner motor 520, a corner silicone pad 530, and an upper lifting component 540. The corner bracket 510 is installed on one side of the frame 100, and the corner motor 520 is installed on the corner bracket 510. Its drive end is connected to the downward-facing corner silicone pad 530 to drive it to rotate. The upper lifting component 540 is located below the corner silicone pad 530 on the same vertical line. The two cooperate to clamp the corner of the pad and flip it. Specifically, the corner silicone pad 530 is close to the upper surface of the pad. One side of the upper lifting component 540 is provided with a positioning unit for detecting the presence of the pad. When the pad is transferred, the upper lifting component rises and cooperates with the corner silicone pad 530 to clamp a corner of the pad. The corner motor 520 drives the silicone pad to rotate 90°. The two longitudinal sides of the frame 100 are greater than the maximum distance generated when the pad rotates, thus completing the flipping. This converts the processed side of the pad into an adjacent side, allowing the pad to continue to be polished by the rear grinding mechanism 400.

[0044] Furthermore, such as Figure 5As shown, a alignment guide assembly 700 is provided between the plate placement mechanism 200 and the front grinding mechanism 300. This assembly includes an edge-correcting wheel 710, several edge-correcting rods 720, an edge-correcting block 730, and an edge-correcting motor 740. The edge-correcting motor 740 is mounted on a mounting plate 750 on the frame 100. The mounting plate 750 has the edge-correcting block 730 and the edge-correcting motor 740. The drive end of the edge-correcting motor 740 is connected to one end of the edge-correcting rod 720, and its other end passes through the edge-correcting block 730 and connects to the edge-correcting wheel 710. The several edge-correcting rods 720 are arranged in two layers, both tilted outwards, and guided in the direction of the front grinding mechanism 300. Specifically, since the pad is not close to one side of the grinding mechanism during transport or placement, the alignment guide assembly 700 is provided. The edge-correcting wheel 710 and the edge-correcting rods 720 guide the pad to enter the grinding mechanism in the center, preventing deviation.

[0045] Furthermore, such as Figure 7 As shown, a support plate 240 is also provided on one side of the plate-laying mechanism 200. A double-plate detection assembly 250 is provided on the support plate 240, including a micro-motion bracket 251, an elastic support plate 252, and a roller 253. The micro-motion bracket 251 is mounted on the support plate 240, and an inclined elastic support plate 252 is located below the micro-motion bracket 251. A roller 253 is located at the other end of the elastic support plate 252, and the rolling direction of the roller 253 is consistent with the movement direction of the pad. The roller 253 and the elastic support plate 252 work together to detect whether the plates are stacked. If the plates are stacked, the roller 253 will block the transport of the upper pad, causing the two plates to separate and preventing the double plates from being mistakenly delivered.

[0046] Furthermore, such as Figure 6As shown, the plate-laying mechanism 200 also includes a suction cup moving assembly 210, a plate-laying lifting assembly 220, and a lateral moving assembly 230. The plate-laying lifting assembly 220 is connected to the edge side of the frame 100, and the lateral moving assembly 230 is movably disposed above the frame 100. The suction cup moving assembly 210 is connected to the drive end of the lateral moving assembly 230, and moves the plate lifted by the plate-laying lifting assembly 220 laterally to the frame 100. Specifically, the plate-laying lifting assembly 220 lifts the reserved plate, and the suction cup moving assembly 210 adsorbs the plate and moves it laterally to the frame 100, realizing automatic plate retrieval and reducing manual intervention. The transverse movement assembly 230 includes a transverse movement tray 231, a transverse movement cylinder 232, two transverse movement slide bars 233, and a transverse movement drive rod 234. Sealing plates 260 are provided on both longitudinal sides of the frame 100 near the plate-laying mechanism 200. The two transverse movement slide bars 233 are respectively mounted on the corresponding sealing plates 260. The transverse movement cylinder 232 is mounted on the support plate 240, and its driving end is connected to the transverse movement tray 231, which slides on the two transverse movement slide bars 233, to drive the transverse movement tray 231 to move laterally. A transverse movement drive rod 234, flush with the transverse movement tray 231, is provided below the transverse movement tray 231. A suction cup moving assembly 210 is connected below the transverse movement tray 231. The suction cup moving assembly 210 includes a suction cup 211 and a suction cup lifting cylinder 212. The suction cup lifting cylinder 212 is configured in two sets and is respectively connected to both ends of the transverse drive rod 234. The drive end of the suction cup lifting cylinder 212 is connected to multiple suction cups 211. The multiple suction cups 211 move up and down synchronously to pick up the pad on the plate lifting assembly 220 and move it to the conveying mechanism.

[0047] Furthermore, such as Figure 8 As shown, the plate collection mechanism 600 is mounted on the frame 100 and corresponds to the other side of the plate placement mechanism 200. The plate collection mechanism 600 includes a transverse plate-pressing assembly 610, a longitudinal plate-pressing assembly 620, and a plate collection lifting assembly 630. The plate collection lifting assembly 630 is connected to the edge side of the frame 100. The transverse plate-pressing assembly 610 is positioned above the plate collection lifting assembly 630, and the longitudinal plate-pressing assembly 620 is positioned above the frame 100. The transverse plate-pressing assembly 610 and the longitudinal plate-pressing assembly 620 work together to arrange the plates neatly.

[0048] Furthermore, such as Figure 8As shown, the transverse clapping assembly 610 includes a handle 611, a transverse clapping slider 612, a clapping rod 613, an adjusting plate 614, and a transverse clapping cylinder 615. The transverse clapping cylinder 615 is installed on the retracting frame 616 above the retracting lifting assembly 630. The driving end of the transverse clapping cylinder 615 is connected to the adjusting plate 614. The adjusting plate 614 is provided with an opening slot 617, and the opening slot 617 is provided with a handle 611 that can slide back and forth. Rotating the handle 611 can lock it in a certain position in the opening slot 617. The lower side of the handle 611 is also provided with a transverse clapping slider 612, and the lower end of the transverse clapping slider 612 is provided with two longitudinally aligned clapping rods 613.

[0049] Furthermore, such as Figure 8 As shown, the longitudinal clapping assembly 620 includes a material straightening rod 621, a baffle plate 622, and a longitudinal clapping cylinder 623. The material straightening rod 621 is located below the receiving frame 616. The material straightening rod 621 is equipped with a detachable longitudinal clapping cylinder 623.
