[0025] The present invention provides Figure 1-9An FPC fully automatic board mounting machine shown includes a transport module 1 for transporting and caching blocking carriers, a four-axis robot transport module 2 for transporting FPCs, steel sheets, separators and attaching tapes, a lifting hopper module 3 for stacking and loading materials, a CCD vision module 4 for guiding robot movement and detecting attachment effects, a high-temperature tape cutting module 5 for cutting the high-temperature tape in roll form into small pieces of tape, and a paper recycling module 6 for recycling separators. In this embodiment, the FPC fully automatic board mounting machine is mainly used for the process in which FPCs need to be attached and fixed on a carrier in the SMT production process, replacing manual operations and realizing automated operations.

[0026] like Figures 2 to 4 As shown, the conveying module 1 includes a conveying channel 11 for conveying a carrier, including a buffer component 12 for buffering and blocking at the front section of the conveying channel, and a positioning component 13 for limiting the carrier at the rear section of the conveying channel.

[0027] The conveying channel 11 is used to connect the front and rear equipment, realize the automatic incoming material of the carrier, and automatically discharge the attached FPC carrier. The conveying channel 11 includes a first conveying track 111 and a second conveying track 112 placed opposite each other. The first conveying track 111 and the second conveying track 112 are each equipped with a conveying belt 113, a belt tensioning pulley 114, a driving pulley 115, a conveying idler pulley 116, a conveying motor 117, and a channel rib 118. The conveying motor 117 is directly connected to the driving pulley 115 and rotates to drive the conveying belt 113 to transport the carrier. Since the configuration and connection method of the conveying track 11 are common knowledge well known to those skilled in the art, they will not be described in detail here.

[0028] like Figure 4 As shown, the buffer assembly 12 includes a first blocking cylinder 121, a second blocking cylinder 123, a third blocking cylinder 124, and a blocking cylinder spacer 122 installed under the blocking cylinder for connecting to the bottom plate to adjust the blocking front and rear positions. The first blocking cylinder 121 and the second blocking cylinder 123 are used to buffer the carrier, saving the time for the carrier to flow to the positioning assembly 13. The first blocking cylinder 121, the second blocking cylinder 123, and the third blocking cylinder 124 are placed at equal intervals below the transport flow channel 11.

[0029] like Figure 3 、 Figure 4As shown, the positioning assembly 13 includes a side push assembly 131 and a lifting assembly 132. The side push assembly 131 is arranged on the side of the first transport track 111 through a connecting piece. When the carrier is in place, the side push assembly 131 and the lifting assembly 132 push the carrier toward the flow channel retaining edge 117 of the second transport track 112 to complete the side positioning. The lifting assembly 132 includes an adjustable positioning pin 1321, a lifting guide 1322, a lifting support plate 1323, and a lifting cylinder 1324. The lifting cylinder 1324 is connected to the lifting support plate 1323 through a connecting ring and a snap ring. The adjustable positioning pin 1321 is installed on the lifting plate 1323, and the lifting guides 1322 are distributed on both sides of the cylinder. The lifting cylinder 1324 drives the lifting plate 1323, and the adjustable positioning pin 1321 moves in the direction guided by the lifting guide 1322. The lifting plate 1323 with a pin hole on the carrier is raised. The adjustable positioning pin 1321 will lift the carrier off the belt surface. The adjustable positioning pin 1321 will pass through the pin hole on the carrier to limit the carrier. The adjustable positioning pin 1321 will also be higher than the carrier surface to guide and position the FPC. The adjustable positioning pin 1321 can adjust the position of the pin according to different fixtures to improve compatibility.

[0030] like Figure 3 As shown, a width adjustment component 14 is installed on the transport channel 11, and the width adjustment component 14 includes a width adjustment slide rail 141, a width adjustment slider 142, a T-shaped screw rod 143 and an adjustment hand wheel 144. The width adjustment slide rail 141 and the width adjustment slider 142 are installed on the first transport track 111, and the T-shaped screw rod 143 and the adjustment hand wheel 144 are installed on the second transport track 112 as fixed ends. The width adjustment component 14 allows the transport channel 11 to be suitable for carriers of different sizes. Since the setting method and connection method of the width adjustment component 14 and the transport channel 11 are common knowledge well known to those skilled in the art, they will not be repeated here.

[0031] As attached Figure 5 To the attached Figure 6 As shown, the four-axis manipulator handling module 2 includes a manipulator base 21, a four-axis manipulator 22, a vacuum suction nozzle assembly 23, and a tape removal assembly 24. The manipulator base 21 spans the transport channel 11, and the four-axis manipulator 22 is installed on the manipulator base 21. The vacuum suction nozzle assembly 23 for sucking FPC, steel sheet, and separator paper is installed on the four-axis manipulator 22, and the tape removal assembly 24 is installed on the vacuum suction nozzle assembly 23. Through the movement of the four-axis manipulator 22, the vacuum suction nozzle assembly 2 is cooperated with the vacuum suction nozzle assembly 2 to transport the FPC or steel sheet from the silo to the carrier, and the separator paper is transported to the separator paper recovery module 6.

[0032] like Figure 6As shown, the vacuum nozzle assembly 23 includes a knob screw 231, an eight-claw nozzle mechanism 232, and a buffered nozzle 233. The eight-claw adjustment mechanism 232 has a connection block in the middle that is connected to the four-axis robot. Due to the high degree of customization of FPC materials, there are often multiple hollows, and the position of the nozzle needs to be adjusted frequently. The buffered nozzle 233 is installed on the eight-claw adjustment mechanism 232. The eight-claw adjustment mechanism 232 can be adjusted forward and backward. The workpiece at the end can be rotated around the rotation center and can also be adjusted forward and backward. In conjunction with the knob screw 231, the position of the buffered nozzle 233 can be quickly adjusted.

[0033] like Figure 6 As shown, the tape taking and applying assembly 24 includes a first glue cylinder 241, a second glue cylinder 242, and a glue pressing head 243. The first glue cylinder 241 and the second glue cylinder 242 are placed side by side and fixed together with the vacuum suction nozzle assembly 23 through a connecting block. The first glue cylinder 241 and the second glue cylinder 242 are both equipped with a glue pressing head 243 with the same structure. The glue pressing head 243 is a workpiece composed of multiple materials and the lower surface in contact with the tape is a layer of porous silicone material. It uses the adhesiveness and vacuum adsorption force of the silicone to the high-temperature tape to remove the high-temperature tape from the high-temperature tape cutting module 5 (the sticky side of the high-temperature tape faces down). Above the silicone is a layer of soft foam with holes, which is used to absorb the thickness difference between the FPC and the carrier, so that the high-temperature tape can be better attached to the FPC and the carrier, avoiding the tape being attached with empty gaps. The purpose of the holes is to allow the vacuum air path to pass all the way to the high-temperature tape (which is conducive to the air path generating vacuum to absorb the tape and using the air path to blow air for sticking the tape). The last layer is the metal material used to connect the cylinder.

[0034] like Figure 5 As shown, the CCD vision module 4 for guiding the movement of the manipulator and detecting the attachment effect includes an upper detection CCD41 and a lower correction CCD42. The upper detection CCD41 connects the upper camera 412, the upper lens 413, and the upper light source 414 to the vacuum suction nozzle assembly 23 through the upper connecting plate 411. The main functions of the upper detection CCD41 are: 1. Determine whether it is a separator or FPC; 2. Calculate the actual position and angle of the FPC in the hopper, and cooperate with the four-axis manipulator 22 to adjust the suction position of the vacuum suction nozzle assembly 2 to improve the suction success rate; 3. Detect the effect of attaching high-temperature tape or stainless steel pressing sheet (4. Before attachment, the upper detection CCD41 detects the carrier position and confirms whether the pin 1321 is normally positioned on the FPC board), the lower correction CCD42 includes a lower connecting plate 421, a lower camera 422, a lower lens 423, and a lower light source 424. The main function of the lower correction CCD42 is to correct the FPC or steel sheet being absorbed before attachment.

[0035] like Figure 7As shown, the lifting silo module for stacking and loading includes a stainless steel tablet lifting silo 31 and an FPC lifting silo 32. The stainless steel tablet lifting silo 31 and the FPC lifting silo 32 for stacking and loading are arranged in sequence along the flow direction on the right side of the front section of the conveying channel 11. The stainless steel tablet lifting silo 31 and the FPC lifting silo 32 have similar structures, and both have a reduction motor 38, a lifting ball screw 37, a guide column 35, a material discharge platform 34, a length direction limit side adjustment member 33, and a width direction limit side adjustment member 34. 6, the reduction motor 38 is connected to the lifting ball screw 37 through a coupling, and the rotation of the screw drives the nut to move up and down. One end of the guide column 35 is fixed to the nut through a connecting block, and the other end is fixed to the discharge platform 34. The length direction limit edge adjustment member 33 and the width direction limit edge adjustment member 36 are used to adjust the limit edge in the center. The structure is composed of a slide rail, a slider, a forward and reverse threaded screw, a bearing, a bearing seat, a limit edge, and an adjusting wheel. The setting method and connection method are common knowledge well known to those skilled in the art and will not be repeated here.

The feeding component 51 is used to limit and fix the high-temperature tape, and includes a barrel support rod 515. The barrel support rod 515 is equipped with a barrel 513, an elastic block 511 is embedded in the barrel 513 and is lifted up by a spring, a limit block 514 is installed on the side of the barrel 513, and a tension adjustment nut 512 is provided in the middle of the barrel 513. The elastic block 511 is used to clamp the inner ring of the high-temperature tape, and there is a spring behind the tension adjustment nut 512. By rotating The tension adjustment nut 512 controls the compression amount of the spring, controls the rotation of the barrel 513, and maintains the tension of the tape. The film guide assembly 52 is used to ensure that the film does not deviate when being pulled, and includes a guide wheel 521, a guide shaft 522, and a guide height adjustment block 523.

The non-stick base 531 is installed on the shift cylinder 532. The upper surface of the non-stick base 531 is coated with a special non-stick coating and has vacuum adsorption holes. The high-temperature tape after cutting is kept in place by vacuum adsorption. The second lifting cylinder 534 is set, and the first lifting cylinder 533 is used to achieve three stop positions in height. The lowest position is the avoidance position, which is in the film pulling state at this time. The middle position is the die position, which is in the cutting state at this time. The highest position is the film discharge position, which is in the state of removing the tape assembly 24 to remove the mold. The transposition cylinder 532 can be used to achieve two pieces of cut high-temperature tape on the non-stick base 531. The die assembly 54 includes a die cylinder 541 and a pressing module 542. The pressing module 542 is installed on the die cylinder 541 and cooperates with the first lifting cylinder 533 to press the high-temperature film firmly on the non-stick base 531. This is to prevent the high-temperature tape from running away when the film clamping cylinder is released.(One side of the high-temperature tape is sticky) As described above, the film pulling assembly 55 includes a film clamping fixture 551, a film clamping cylinder 552, a film clamping cylinder connecting block 553, a film pulling shaft 554, the film clamping fixture 551 is installed at the front end of the film clamping cylinder 552, and the film clamping cylinder 552 is fixed to the mover of the film pulling shaft 554 through the film clamping cylinder connecting block 553. The film clamping fixture 551 is composed of a pair of workpieces with matching concave and convex arc surfaces. The structure of the arc surface is to enhance the strength of the film exposed in front of the film clamping fixture 551, and to ensure that the posture of the film is neither warped upward nor bent downward. The surface of the workpiece with the concave arc surface is made of soft material to avoid point contact, ensure balanced force during clamping, and increase the stability of the film pulling. The film pulling shaft 554 is used to bring The dynamic film clamping cylinder 552 reciprocates to pull the film, and adopts a synchronous belt drive, which includes a horizontal plate, a vertical plate, a motor, a synchronous belt, a synchronous wheel, a guide rail, a slider, and a synchronous belt pressure block.

The cutting component 56 includes pneumatic scissors 561, a avoidance cylinder 562, a pneumatic scissor connecting block 563, and the pneumatic scissors 561 is fixed to the avoidance cylinder 562 through the pneumatic scissor connecting block 562. The avoidance cylinder 562 is installed on the film pulling shaft 554 and moves with the film clamping cylinder 552. Only when cutting does the avoidance cylinder 562 push the pneumatic scissors 561 forward, and it returns to its original position after cutting.

[0037] like Figure 9 As shown, the recycling module 6 for recycling the separator paper is on the left side of the transport channel, and includes a recycling support plate 61, a recycling flat plate 62, and a recycling limit block 63. The recycling support plate 61 is on both sides, and the recycling flat plate 62 is located above the recycling support plate 61. The recycling limit blocks 63 are erected on three sides of the recycling flat plate 62.

As described above, the film-pulling assembly 55 includes a film clamping jig 551, a film clamping cylinder 552, a film clamping cylinder connecting block 553, and a film-pulling shaft 554. The film clamping jig 551 is mounted on the front end of the film clamping cylinder 552, and the film clamping cylinder 552 is fixed to the mover of the film-pulling shaft 554 via the film clamping cylinder connecting block 553. The film clamping jig 551 is composed of a pair of workpieces with matching concave and convex arc surfaces. The arc structure is designed to enhance the strength of the film exposed in front of the film clamping jig 551, ensuring that the film's posture neither warps upward nor bends downward. The workpiece surface of the concave arc surface is made of a soft material to avoid point contact, ensure balanced force during clamping, and increase film-pulling stability. The film-pulling shaft 554 is used to drive the film clamping cylinder 552 to move back and forth to pull the film.
