Description

Technical Field

[0001] This invention relates to the field of catalyst technology, and in particular to a PSA small-particle attaching machine. Background Technology

[0002] PSA (pressure-sensitive adhesive) is a type of adhesive that is sensitive to pressure. It is mainly used in the manufacture of pressure-sensitive tapes. The adhesive force (the peel force exhibited when the adhesive tape is pressed against the adhered surface) of a pressure-sensitive adhesive must be greater than the tack force (the tactile adhesion felt when lightly touching the tape with a finger). Based on its main components, it can be divided into two categories: rubber-based and resin-based. In addition to the main components, other auxiliary components are added, such as tackifying resins, plasticizers, fillers, viscosity modifiers, vulcanizing agents, antioxidants, and solvents.

[0003] Currently, PSA (Polyester Acid) application to the surface of FPC products is usually done manually. Due to the small size of the film and the high requirements for positional accuracy, manual picking and applying during the application process is quite difficult. Furthermore, manual picking, placing, and flipping can easily cause surface damage, deformation, and contamination to the product, resulting in a high product defect rate and low efficiency.

At the same time, the thermocouple can heat and soften the adhesive on the product, making it easier to apply.

[0057] The unloading and handling device 8 includes a third multi-axis moving assembly 81, under which a fourth suction cup picking head 82 is installed. The fourth suction cup picking head 82 is connected to the third multi-axis moving assembly 81 via a three-XY axis fine-tuning platform and a third θ axis displacement platform. The unloading and handling device 8 is also equipped with an unloading positioning camera 83, an unloading carrier plate camera group 84, and an ion air bar, all of which are existing equipment and will not be described in detail. The third multi-axis moving assembly 81 and the fourth suction cup picking head 82 work together to pick up materials from the second flipping arm 33 and transfer them to the unloading positioning camera 83 for photographing and alignment. The unloading carrier plate camera group 84 can photograph and align OK unloading carrier plates or NG unloading carrier plates. The products are corrected by the three-XY axis fine-tuning platform and the third θ axis displacement platform. In the serial mode, the unloading and handling arm directly places OK-attached products onto the conveyor belt of the downstream equipment for transfer; in the non-serial mode, the unloading and handling arm places OK-attached FPC products onto the carrier plate of the magazine unloading device 9, and NG-attached FPC products onto the NG-attached unloading device 18. The third multi-axis moving assembly 81 and the second multi-axis moving assembly 51 are existing XYZ three-axis moving assemblies; the first multi-axis moving assembly 41 is an existing XY two-axis moving assembly; the first XY axis fine-tuning platform, the first θ axis displacement platform, the second XY axis fine-tuning platform, the second θ axis displacement platform, the third XY axis fine-tuning platform, and the third θ axis displacement platform are all existing equipment and will not be described in detail; the PSA picking head, the third suction cup picking head 43, the fourth suction cup picking head 82 and the first suction cup picking head adopt mature existing technology and will not be described in detail; each camera, camera group and camera assembly can be finely adjusted in height by slide rails and adjusting bolts; the position and angle of each code reading group can be finely adjusted by guide rods.

[0058] Please see Figure 1 , Figures 22 to 23In one embodiment of the present invention, a resistance pressure roller mechanism is provided on the side of the peeling mechanism 63 away from the peeling plate 632. The resistance pressure roller mechanism includes a mounting frame 11. A third roller 15 is installed at the bottom of the mounting frame 11. A pressure roller 16 is installed above the third roller 15 in the mounting frame 11. The pressure roller 16 is installed in the mounting frame 11 through a pressure adjusting component 12. A film changing component 13 is provided on the mounting frame 11 above the pressure roller 16. The film changing component 13 includes a handle 133, a handle shaft 132, and a limiting block 131. The limiting block 131 is installed on the side of the mounting frame 11. The handle shaft 132 is movably installed on or below the limiting block 131. A changing groove 134 is provided at the position where the handle shaft 132 contacts the limiting block 131. One end of the handle shaft 132 is connected to the handle 133. The handle shaft 132 is connected to the pressure adjusting component 12. The material roll first passes between the third roller and the pressure roller of the resistance pressure roller mechanism, and then passes through the peeling mechanism 63. A pressure adjustment assembly 12 is provided on each side of the mounting frame 11. The pressure adjustment assembly 12 includes a lifting slider and a first adjusting bolt 122. Lifting grooves for lifting sliders are provided on both sides of the mounting frame 11. Lifting sliders are installed in the lifting grooves. The first adjusting bolt 122 is connected to the lifting slider. The pressure roller 16 is sleeved on the pressure roller shaft 161. The two ends of the pressure roller shaft 161 are respectively inserted into the corresponding lifting sliders on both sides. A limiting block 131 is horizontally installed on both the left and right sides of the mounting frame 11. The two ends of the handle shaft 132 pass through the corresponding holes of the lifting slider's handle shaft 132, contacting the corresponding limiting block 131. A first spring connects the bottom surface of the lifting slide to the lower end surface of the lifting slider. A second spring connects the first adjusting bolt 122 to the lifting slider. Rotating the first adjusting bolt 122 adjusts the position of the pressure lifting slider within the mounting frame 11, thereby adjusting the pressure between the roller 15 and pressure roller 16 installed between the two lifting sliders. Due to the first and second springs, the lifting slider has an adjustment margin for vertical movement, allowing space for material replacement. Guide protrusions (not labeled) are provided on the front and rear surfaces of both lifting slides, and guide grooves (not labeled) are provided at corresponding positions on the lifting sliders, cooperating with the guide protrusions to provide guidance. The third roller 15 is fitted onto the roller 15 shaft, and the two ends of the third roller 15 shaft extend out of the two sides of the mounting frame 11 respectively. The first resistance adjustment component 14 is installed on the right side outside the mounting frame 11, and the second resistance adjustment component 17 is installed on the left side outside the mounting frame 11. Both are used to adjust the resistance to the roller 15 shaft.The first resistance adjustment assembly 14 includes a mounting plate 141, a second adjusting bolt 142, a pressure block 143, and a connector 144. The second adjusting bolt 142 is inserted upward through the mounting plate 141. The pressure block 143 is disposed between the corresponding section of the mounting plate 141 and the roller 15 shaft, and the pressure block 143 contacts the circumferential surface of the roller 15 shaft. The connector 144 is disposed between the mounting plate 141 and the pressure block 143. The end of the second adjusting bolt 142 near the roller 15 shaft is connected to the connector 144. The structure of the second resistance adjustment assembly 17 is the same as that of the first resistance adjustment assembly 14, and it is mounted mirror-image of the first resistance adjustment assembly 14 on the left side outside the mounting frame 11. The second adjusting bolt 142 drives the connector to move, thereby adjusting the contact pressure between the pressure block 143 and the roller 15 shaft, and thus adjusting the resistance of the roller shaft 151. The working principle of the second resistance adjustment assembly is the same. The second resistance adjustment assembly 17 is installed via a connecting plate 171, which is fixed to the bottom left side of the mounting frame 11. A support column 172 is fixed to the left edge of the connecting plate 171. The second mounting plate 173 of the second resistance adjustment assembly 17 is fixed to the support column 172. The second resistance adjustment assembly 17 is located on the roller shaft 151. The first mounting plate 141 of the first resistance adjustment assembly 14 is fixed to the right edge of the lower surface of the mounting frame 11. The first resistance adjustment assembly 14 is located below the roller shaft 151. During assembly, first, the position of the lifting slider of the pressure adjusting assembly 12 within the mounting frame 11 is adjusted by rotating the first adjusting bolt 122. This adjusts the pressure between the roller 15 and pressure roller 16 installed between the two lifting sliders. After adjusting the pressure, a limiting block 131 is installed at the corresponding position on the mounting frame 11. The handle shaft 132 is then threaded through the two lifting sliders, passing through the two handle shaft holes in sequence, so that the two shifting grooves 134 of the handle shaft 132 engage with the limiting blocks 131 at the corresponding positions on the mounting frame 11. Because a first spring is provided between the lifting slider and the lifting groove, and a second spring is provided between the lifting slider and the first adjusting bolt 122, the lifting slider can move up and down to a certain extent. The adjustment margin is adjusted by rotating the film changing assembly 13 so that the shifting groove 134 of the handle shaft 132 no longer gets stuck in the limiting block 131. This causes the pressure adjusting assembly 12 to move upward, thereby moving the pressure roller 16 away from the roller 15 to make room for changing the PSA small material roll. Reverse rotation of the film changing assembly 13 causes the shifting groove 134 to get stuck in the limiting block 131 again. Under the combined action of the first spring and the second spring of the pressure adjusting assembly 12, it naturally moves downward back to its original position to maintain the original pressure. This mechanism can retain the original pressure of the pressure roller entering the roller, eliminating the need to readjust the pressure, simplifying the reloading process, reducing the debugging work of the staff, and greatly improving the efficiency of changing materials.

[0059] Please see Figure 1 , Figures 6 to 13 , Figure 20 , Figure 21In one embodiment of the present invention, the magazine unloading device 9 includes a third magazine loading / unloading conveying mechanism 91 and a third magazine lifting mechanism 94. The third magazine loading / unloading conveying mechanism 91 and the third magazine lifting mechanism 94 are opposite to each other. The third magazine loading / unloading conveying mechanism 91 has the same structure as the first magazine loading / unloading conveying mechanism 211, and the third magazine lifting mechanism 94 has the same structure as the first magazine lifting mechanism 212. A second carrier plate ejection mechanism is respectively provided on both sides of the docking position of the third magazine lifting mechanism 94. 93, the second carrier plate ejection mechanism 93 has the same structure as the first carrier plate ejection mechanism 24; a unloading carrier plate transfer mechanism 94 is provided between the second carrier plate ejection mechanism 93 and the third magazine lifting mechanism, and a third cover plate removal mechanism 95 is provided above this position; the unloading carrier plate transfer mechanism 94 has a similar structure to the loading carrier plate transfer mechanism 25, and the unloading carrier plate transfer mechanism 94 includes a second carrier plate moving assembly 941, on which a second carrier plate insertion / removal assembly 942 is mounted; the second The carrier plate insertion / removal assembly 942 includes a second lifting plate with multiple second lifting positioning posts. The second lifting plate is mounted on the second carrier plate moving assembly 941 via a second lifting cylinder. Two second guide assemblies 943, whose edges on the upper surface of the second carrier plate moving assembly 941 are perpendicular to the moving direction of the second carrier plate moving assembly, clamp the second carrier plate insertion / removal assembly 942 in the middle. One of the second guide assemblies 943 is fixed to the second carrier plate moving assembly 941 via a slider guide rail, and the slider and guide rail can be locked together. Each of the two second guide assemblies 943 is equipped with a second carrier plate clamping member 944, which includes a second clamping cylinder mounted on the outside of the second guide assembly. A second clamping plate is mounted on the second clamping cylinder for pressing down on the carrier plate placed on the second roller of the second guide assembly 943. The third cover plate removal mechanism 95 includes a third moving assembly with Z-axis lifting, and a third cover plate adsorption assembly is mounted on the third moving assembly. A second carrier plate reader and a second magazine reader aligned with the third magazine lifting mechanism 94 are provided above the position where the unloading carrier plate transfer mechanism 94 docks with the third magazine lifting mechanism 94.The second carrier plate ejection mechanism 93, located away from the unloading carrier plate transfer mechanism 94, pushes the carrier plate out of the magazine held by the third magazine lifting mechanism 94. The second clamping cylinders on both sides of the unloading carrier plate transfer mechanism press down to fix it. The second lifting cylinder of the second carrier plate insertion and removal assembly 942 lifts up, causing the second lifting positioning pin to pass upward into the positioning hole on the carrier plate and contact the cover plate, lifting it up. The third cover plate removal mechanism descends to remove the cover plate. The unloading carrier plate transfer module moves to the receiving position, and after being filled, moves back to the cover plate position. The third moving assembly descends and picks up the cover plate from the carrier plate through the third cover plate adsorption assembly. Then, the second carrier plate moving assembly 941 drives the second carrier plate. The insertion / removal assembly 942 moves to the receiving position to receive the OK product transported by the unloading and conveying device 8. The second lifting cylinder of the second carrier plate insertion / removal assembly 942 retracts, and the lifting plate moves downward, causing the second lifting positioning pin on it to disengage from the positioning hole on the carrier plate. Then, the second carrier plate moving assembly 941 drives the second carrier plate insertion / removal assembly 942 to move to the initial position. The third moving assembly descends, and the third cover plate adsorption assembly places the cover plate on the carrier plate and continues to move downward to press the cover plate back onto the carrier plate. The cylinder of the second carrier plate ejection mechanism 93, which is in contact with the unloading carrier plate transfer mechanism 94, pushes out to push the carrier plate back into the magazine. The preferred structure of the second guide assembly 943 is similar to that of the first guide assembly 252. The unloading carrier plate transfer mechanism 94 and the loading carrier plate transfer mechanism 25 are similar in structure except that the installation positions of the first guide component and the second guide component are different, and the first carrier plate insertion component has a first blocking cylinder 2542 and a first pushing cylinder 2543 compared to the second carrier plate insertion component.

[0060] Please see Figure 1 , Figures 6 to 13In one embodiment of the present invention, the FPC magazine loading device 2 includes a magazine dispensing module 21, a first cover plate removal module 23, and a magazine receiving plate module 22. The magazine dispensing module 21 includes a first magazine infeed / outfeed conveying mechanism 211 and a first magazine lifting mechanism 212. The magazine receiving plate module 22 includes a second magazine infeed / outfeed conveying mechanism 221 and a second magazine lifting mechanism 222. One end of the first magazine infeed / outfeed conveying mechanism 211 is connected to the first magazine lifting mechanism 212, and one side of the first magazine lifting mechanism 212 is connected to a first plate ejection mechanism 24, which is used to push out the plate from the magazine held by the first magazine lifting mechanism 212 piece by piece. The other side of the first magazine lifting mechanism 212 is connected to one end of a loading plate transfer mechanism 25, and the other end of the loading plate transfer mechanism 25 is connected to one side of the second magazine lifting mechanism 222, which is used to receive the plate pushed out from the magazine held by the first magazine lifting mechanism 212 and send it into the second magazine lifting mechanism. Inside the empty magazine held by 222, the second magazine lifting mechanism 222 is connected to the second magazine loading / unloading conveying mechanism 222; the loading plate transfer mechanism 25 is equipped with the first cover plate removal module 23, which is used to remove the cover plate on the plate, place the full magazine on the first magazine loading / unloading conveying mechanism, the first magazine lifting mechanism 212 removes the full magazine, and the first plate ejection mechanism 24 pushes the plate inside the magazine onto the loading plate transfer mechanism 25, and the loading plate transfer mechanism 25 and the first cover plate removal module... 23. Remove the cover plate from the carrier plate. The second magazine lifting mechanism 222 takes an empty magazine from the second magazine loading and unloading conveying mechanism 221. Then, the empty carrier plate is pushed from the carrier plate transfer mechanism 25 onto the empty magazine on the second magazine lifting mechanism 222. After the empty magazine is full, it is placed on the second magazine loading and unloading conveying mechanism 221. This replaces the manual operation of the carrier plate for picking up and opening, which helps to improve production efficiency and protect the carrier plate and cover plate, reduce production losses, and lower production costs.The first magazine loading / unloading conveying mechanism 211 includes a first-layer conveying component 2111 and a second-layer conveying component 2112, with the second-layer conveying component 2112 mounted on the first-layer conveying component 2111. The first magazine lifting mechanism 212 includes a Z-axis lifting drive component 2121, an X-axis horizontal drive component 2122 mounted on the Z-axis lifting drive component 2121, and a magazine gripping component 2123 mounted on the X-axis horizontal drive component 2122 for gripping magazines placed on the first-layer conveying component 2111 and the second-layer conveying component 2112. The structure of the second magazine loading / unloading conveying mechanism 221 is the same as that of the first magazine loading / unloading conveying mechanism 211. The structure of the second magazine lifting mechanism 222 is the same as that of the first magazine lifting mechanism 212. Through the cooperation of the Z-axis lifting drive component 2121 and the X-axis horizontal drive component 2122, magazines can be picked up and placed near the first magazine loading / unloading conveying mechanism 211, and then moved vertically away from the first magazine loading / unloading conveying mechanism 211.

[0061] A first carrier plate reader 26 is located next to the first cover plate module 23. A first magazine reader 27, aligned with the first magazine lifting mechanism 212, is installed on the first carrier plate ejection mechanism 24. The magazine reader is used for recording. A specified number of third inductive photoelectric sensors 2113 are installed on both the first-layer conveying assembly 2111 and the second-layer conveying assembly 2112. A magazine-blocking cylinder 2115 is installed on the second-layer conveying assembly 2112. A micro switch 2114 is installed at the end of the first-layer conveying assembly 2111 away from the first magazine lifting mechanism 212, and a micro switch 2114 is installed at the end of the second-layer conveying assembly 2112 near the first magazine lifting mechanism 212. When the micro switch 2114 is triggered, it indicates that the magazine has been conveyed to the correct position, and the conveying assembly needs to stop. The magazines are then removed. It should be noted that the first-layer conveyor assembly 2111 and the second-layer conveyor assembly 2112 are separate units, namely a left conveyor belt and a right conveyor belt. The two conveyor belts operate synchronously, and there is space between the left and right conveyor belts for the first magazine lifting mechanism 212 or the second magazine lifting mechanism 222 to operate, which is convenient for gripping the magazines placed on them or for placing the magazines on them. This space can also be used to install sensors and magazine-blocking cylinders 2115. There are three third photoelectric sensors 2113. When all three photoelectric sensors are blocked, it means that the second-layer conveyor assembly 2112 is full of magazines, and the second-layer conveyor assembly 2112 can no longer convey magazines towards the first magazine lifting mechanism 212.

[0062] The magazine clamping assembly 2123 includes an L-shaped first mounting plate 21231, which is mounted on an X-axis horizontal drive assembly 2122. The opening of the first mounting plate 21231 faces the first magazine infeed / outfeed conveyor mechanism 211. A clamping cylinder 21232 is mounted under the first mounting plate 21231, and the push rod of the clamping cylinder 21232 is connected to a first clamping plate. A push cylinder 21233 is mounted on the top of the first mounting plate 21231. The push cylinder 21233 extends downward and connects to a first pressure block. The first mounting plate 21231, the clamping cylinder 21232, and the push cylinder 21233 cooperate to clamp the magazine. The clamping cylinder 21231, through the cooperation of the Z-axis lifting drive assembly 2121 and the X-axis horizontal drive assembly 2122, bypasses the bottom surface of the magazine. The first clamping plate installed on 232 wraps around the front side of the magazine. Then, the clamping cylinder 21232 retracts to clamp the magazine, and the pushing cylinder 21233 presses down to press the magazine. The Z-axis lifting drive assembly 2121 and the X-axis horizontal drive assembly 2122 work together to bring the magazine to the position of the ejection plate, and then bring the magazine to the position of the empty magazine. The clamping cylinder 21232 and the pushing cylinder 21233 work in reverse to place the magazine on the first layer of the conveying assembly 2111. Then, the Z-axis lifting drive assembly 2121 and the X-axis horizontal drive assembly 2122 are used to retrieve a new full magazine. It should be noted that the Z-axis lifting drive assembly 2121 and the X-axis horizontal drive assembly 2122 are both existing technologies and can be used to achieve linear transmission by means of lead screws and nuts, synchronous belts and synchronous pulleys, gears and racks, etc.

[0063] The first carrier plate ejection mechanism 24 includes a third telescopic cylinder 241. The push rod of the third telescopic cylinder 241 is connected to a push plate 242. The pushing direction of the push plate 242 is aligned with the first magazine lifting mechanism 212, and is used to push out the carrier plate in the magazine on the first magazine lifting mechanism 212. The side of the magazine near the first carrier plate ejection mechanism 24 and the side away from it are provided with concave grooves to facilitate the push plate 242 to enter and push the carrier plate out of the magazine. The magazine is provided with multiple layers for placing the carrier plate.

[0064] The loading and transferring mechanism 25 includes a first loading plate moving assembly 251. First guide assemblies 252 are arranged on both sides of the first loading plate moving assembly 251 in its running direction. First loading plate clamping parts 253 are installed on both sides of the first guide assemblies 252. A first loading plate insertion / removal assembly 254 is installed on the first loading plate moving assembly 251. The first loading plate insertion / removal assembly 254 includes a first lifting plate 2541, a first blocking cylinder 2542, and a first pushing cylinder 2543. The first lifting plate 2541... Multiple lifting and positioning columns 2544 are provided. A first lifting plate 2541 is mounted on a first carrier plate moving assembly 251 via a first lifting cylinder 2545. A first blocking cylinder 2542 is mounted on the first carrier plate moving assembly 251, extending upward through the first lifting plate 2541 to act as a blocking limit. A first pushing cylinder 2543 is installed on the side of the first carrier plate moving assembly 251 away from the first magazine lifting mechanism 212. A photoelectric sensor is installed on the first carrier plate moving assembly 251 to... The system detects whether there is a carrier plate on the first carrier plate insertion / removal assembly 254. If there is a carrier plate, the first baffle cylinder 2542 rises to block the carrier plate into position. Then, the first lifting cylinder 2545 pushes the first lifting plate 2541 upward, causing the lifting positioning pin 2544 on it to insert into the positioning hole on the carrier plate. The first carrier plate moving assembly 251 then transfers and feeds the carrier plate. When the carrier plate is transferred to the cover plate removal position, the first pressing cylinders 2531 on both sides of the first carrier plate moving assembly 251 press and fix the carrier plate. The first lifting... Plate 2541 continues to push upward to separate the cover plate and the carrier plate (the cover plate is pressed tightly onto the carrier plate, and there are no holes on the cover plate above the positioning holes of the carrier plate, so the lifting positioning column 2544 will lift the cover plate if it continues to move upward). The first cover plate picking module 23 lowers to pick up the cover plate through the first three-axis moving mechanism, and then transfers it to the cover plate collecting module to place the cover plate. During this process, the carrier plate code is read by the first carrier plate code reader 26. The first lifting plate 2541 and the first moving plate 2511 are connected to the first guide rail 2546, which plays a guiding role.The first carrier plate moving assembly 251 includes a first moving plate 2511, and a lead screw nut (not shown) and a servo motor (not labeled) for driving the linear motion of the first moving plate 2511; a first lifting cylinder 2545 is mounted on the first moving plate 2511, a first blocking cylinder 2542 is mounted on the first moving plate 2511, and a first pushing cylinder 2543 is mounted on the first moving plate 2511; the first guide assembly 252 includes a first side plate 2521, which is mounted next to the running direction of the first carrier plate moving assembly 251. A first roller 2522 is arrayed on the top of the first side plate 2521, and a second roller 2523 is arrayed on the inner top surface of the first side plate 2521. The axes of the first roller 2522 and the second roller 2523 are perpendicular to each other; the first carrier plate clamping member 253 includes a first clamping cylinder 2545. 31. The first clamping cylinder 2531 is installed on the outside of the first side plate 2521. The first clamping cylinder 2531 is equipped with a first clamping plate 2532, which is used to press down on the carrier plate placed on the second roller 2523 of the first guide assembly 252. The first roller 2522 and the second roller 2523 play a guiding role. When it is necessary to push the carrier plate from the loading carrier plate transfer mechanism into the magazine receiving carrier plate module, the first lifting cylinder retracts, so that the lifting positioning pin exits from the positioning hole of the carrier plate. Then, the first carrier plate moving assembly drives the first carrier plate insertion and removal assembly to move away from the magazine receiving carrier plate module, so that the first pushing cylinder is located at the end of the carrier plate away from the magazine receiving carrier plate module. The first pushing cylinder raises the first carrier plate moving assembly and pushes the carrier plate towards the magazine receiving carrier plate module, pushing the carrier plate into the empty magazine. At this time, the first clamping cylinder no longer presses down on the carrier plate.

[0065] The first cover plate removal module 23 includes a first three-axis moving mechanism 231, on which a first cover plate adsorption mechanism 232 is mounted. The first cover plate adsorption mechanism 232 includes a first vacuum suction cup (not labeled) and a first connecting plate (not labeled). The first connecting plate is fixed on the first three-axis moving mechanism 231, and a specified number of first vacuum suction cups are installed under the first connecting plate for adsorbing the cover plates on the carrier plate. Preferably, the first three-axis moving mechanism 231 is an XYZ three-axis moving mechanism, which is prior art and will not be described in detail. Next to the loading carrier plate transfer mechanism 25, a cover plate collection module 28 is provided. The cover plate collection module 28 includes a first material box and a first linear stepper motor. The first material box is mounted on the first linear stepper motor, which drives the first material box to move up and down to keep the height of the material box and the carrier plate consistent. Two first guide pillars are installed under the first material box to guide the lifting and lowering of the first material box 281; first through-beam photoelectric sensors are installed on both sides of the first material box; a first sensing photoelectric sensor for detecting the height of the first material box is installed on one side of the first material box 281; a second sensing photoelectric sensor is installed at the bottom inside the first material box. The first through-beam photoelectric sensor is used to detect the number of times it is blocked, that is, how many cover plates have been placed into the first material box. After a specified number is reached, no more cover plates are placed. The staff needs to remove the cover plates from the material box, then reset it and start receiving cover plates again. It should be noted that the sensors used in this invention are all existing equipment and no specific protection requirements are made.

[0066] Please see Figures 1 to 5 In one embodiment of the present invention, the transfer and flipping conveying device 3 includes a first flipping arm 31, a transfer arm 32, and a second flipping arm 33; a second horizontal moving mechanism 34 is provided between the first flipping arm 31 and the second flipping arm 33, and the transfer arm 32 is mounted on the second horizontal moving mechanism 34; the first flipping arm 31 includes a first turntable 311, a suction telescopic cylinder 312 is mounted on the first turntable 311, a first suction cup picking head 313 is mounted on the head end of the push rod of the suction telescopic cylinder 312, and a vacuum suction cup is mounted on the first suction cup picking head 313; the structure of the second flipping arm 33 is the same as the structure of the first flipping arm 31. The transfer arm 32 includes a second mounting base 321, a large telescopic cylinder 322, and a small telescopic cylinder 323. The second mounting base 321 is mounted on the second horizontal moving mechanism 34. The large telescopic cylinder 322 is mounted on the second mounting base 321. The push rod of the large telescopic cylinder 322 is connected to a second lifting plate 324. The small telescopic cylinder 323 is mounted on the second lifting plate 324. The head end of the push rod of the small telescopic cylinder 323 is equipped with a second suction cup picking head 325. A vacuum suction cup is mounted on the second suction cup picking head 325. The second mounting base 321 moves horizontally on the second horizontal moving mechanism 34, and the large and small telescopic cylinders 323 work together to achieve more precise picking of FPC.

[0067] The second lifting plate 324 extends towards the first tilting arm 31, and the small telescopic cylinder 323 is installed on the second lifting plate 324 near the first tilting arm 31; the highest point of the movement position of the second suction cup picking head 325 is higher than the highest point of the first suction cup picking head 313 when it is tilted upward; when the transfer arm 32 is close to the first tilting arm 31, the first suction cup picking head 313 is located directly below the second suction cup picking head 325; so that the transfer arm 32 can directly pick up the FPC on the first tilting arm 31. The first suction cup picking head 313 is connected to the suction telescopic cylinder 312 via a first buffer member 314. The first buffer member 314 includes a suction cup connecting plate 3141 fixed to the push rod end of the suction telescopic cylinder 312, and a first buffer spring 3142 connected between the suction cup connecting plate 3141 and the first suction cup picking head 313. The second suction cup picking head 325 is connected to the push rod end of the small telescopic cylinder 323 via a second buffer member 326. The structure of the second buffer member 326 is the same as that of the first buffer member 314. This prevents the suction cup picking head from rigidly contacting the FPC and scratching its surface when picking up the FPC. The first flipping arm 31 is installed at one end of the second horizontal moving mechanism 34; the second flipping arm 33 is installed at the other end of the second horizontal moving mechanism 34. The first tilting arm 31 also includes a first mounting base 315, a mounting box 316, and a tilting motor 317. The first mounting base 315 is mounted on the second horizontal moving mechanism 34. The first turntable 311 is mounted on the side of the mounting box 316. The mounting box 316 contains a first pulley and a second pulley, which are connected by a synchronous belt. The second pulley is fixedly connected to the turntable. The first pulley is driven by the tilting motor 317. The tilting motor 317 drives the first pulley to rotate, which in turn drives the second pulley to rotate, thereby rotating the first turntable 311. This causes the suction telescopic cylinder 312 to rotate the first suction cup picking head 313 180°, thus flipping the FPC product adsorbed on it so that its back side faces upward, facilitating the attachment of PSA small materials on the back. The second horizontal moving mechanism 34 is mounted on a support base 35. The first tilting arm 31, the intermediate rotating arm 32, and the second tilting arm 33 move independently on the second horizontal moving mechanism 34.

[0068] The suction telescopic cylinder 312 descends and picks up the FPC product on the contouring platform fixture of the turntable device 7, which has completed the front-side PSA bonding, through the first suction cup picking head; the first flipping arm 31 rotates the suction telescopic cylinder 312 on it by rotating the first turntable 311, thereby picking up and flipping the FPC with the front-side PSA bonded by the first suction cup picking head; it is then handed over to the intermediate transfer arm 32, which is moved close to the position of the first flipping arm 31 by the second horizontal moving mechanism 34. The large telescopic cylinder 322 and the small telescopic cylinder 323 on the intermediate transfer arm 32 work together to make it... The second suction cup head descends to approach the FPC adsorbed on the first flipping arm 31 for suction; then, through the operation of the second horizontal moving mechanism 34 and the transfer arm 32, the FPC is placed on a contouring platform of another turntable device 7 away from the loading and conveying device 4, and rotated to attach PSA small parts on the back; after the PSA is attached to the back, the turntable device 7 is rotated to bring the FPC product back to the original position, and the second flipping arm 33 picks up the FPC product with PSA attached to the front and back through the second horizontal moving mechanism, flips it, and hands it over to the unloading and conveying device 8.

[0069] The present invention has the following working principle:

[0070] The magazine is placed against the magazine-stopping cylinder 2115 on the second-level conveyor assembly 2112. After the operator presses the start button, the magazine-stopping cylinder 2115 descends, transferring the magazine to the middle of the second-level conveyor assembly, and then rises. The second magazine is then placed, the magazine-stopping cylinder 2115 descends, the second-level conveyor assembly 2112 starts, and after the magazine is transferred to the end of the second-level conveyor assembly 2112, the production line stops, and the magazine-stopping cylinder 2115 rises. At this point, the first magazine is waiting to be picked up by the first magazine lifting mechanism 212. The second-level conveyor assembly 2112 can hold a maximum of three magazines. When the first magazine lifting mechanism 212 clamps a full magazine from the second-layer conveying assembly 2112 and moves vertically downwards, the first carrier plate ejection mechanism 24 sequentially pushes the carrier plate out of the magazine. After the magazine is completely empty, it is placed on the first-layer conveying assembly 2111 via the first magazine lifting mechanism 212. The carrier plate enters the loading carrier plate transfer mechanism 25 to separate the carrier plate from the cover plate. The first cover plate removal module 23 descends to remove the cover plate and then transfers it to the cover plate collection module 28 to place the cover plate. During this process, the carrier plate code is read by the first carrier plate code reader 26. Afterwards, the second magazine lifting mechanism 222 receives the empty magazine from the second-layer conveying assembly 2112 of the second magazine inlet and outlet conveying mechanism 221 and moves it to a designated height. When the empty magazine is clamped and descends, the first carrier plate transfer mechanism sequentially pushes the carrier plate on it into the empty magazine. After the magazine is full, the second magazine lifting mechanism 222 places the magazine on the first-layer conveying assembly 2111 of the second magazine inlet and outlet conveying mechanism 221.

[0071] The first multi-axis moving component 41, the first Z-axis picking arm 42, and the third suction cup picking head 43 of the loading and conveying device 4 cooperate to pick up the FPC from the carrier plate on the loading carrier plate transfer mechanism, transfer it to the code reading group 57 on the FPC for code reading, and then transfer it to the FPC precision alignment camera group 45 for precision alignment. The position is corrected by the first XY axis and the first θ axis alignment platform. If the FPC code reading is NG, the FPC is placed on the carrier plate of the code reading NG unloading device 10 for discharge. If the FPC code reading is OK, the FPC product is placed on the contouring platform of the turntable device 7 near the loading and conveying device 4. The turntable device 7 rotates to rotate the FPC product to the attachment position.

[0072] The second multi-axis moving component 51, the second Z-axis picking arm 52, and the PSA picking suction head 53 of the feeding and bonding device 5, located near the feeding and conveying device 4, cooperate with the peeling plate 632 of the PSA feeding device 6 to pick up PSA small parts. These parts are then transferred to the PSA feeding precision alignment camera group 56 for precision alignment. The turntable precision alignment camera group 54 simultaneously photographs the FPC on the turntable. The position is corrected by the second XY-axis fine-tuning platform and the second θ-axis displacement platform. The PSA small parts are then bonded to the FPC on the turntable contouring platform; this is called PSA bonding 1. The turntable device 7, located near the feeding and conveying device 4, rotates and the AOI detection component checks whether the product with bonded PSA small parts is NG / OK.

[0073] Then, it is rotated to a position that facilitates material picking by the transfer and flipping conveyor 3. The FPC product is then flipped by the transfer and flipping conveyor 3 and transported to another turntable device 7. The other turntable device 7 rotates to the bonding station of another feeding and bonding device 5. The other feeding and bonding device 5 picks up PSA small materials from another PSA feeding device 6 and then attaches them to the surface of the flipped side of the FPC product, which is called attaching PSA2. After the PSA small materials are attached to both sides, the other turntable device 7 rotates to check the NG / OK of the product with attached PSA small materials through the AOI detection component.

[0074] Then rotate to a position that facilitates the transfer and flipping transport device 3 to pick up the FPC product; the transfer and flipping transport device 3 takes the FPC and hands it over to the unloading transport device 8. The third multi-axis moving component 81 and the fourth suction cup picking head 82 of the unloading transport device 8 cooperate to pick up the FPC product from the second flipping arm. The unloading transport arm places the OK-attached FPC product on the carrier plate of the magazine unloading device 9, and the NG-attached FPC product is placed on the NG-attached unloading device 18 for unloading.
