Description

Technical Field

[0001] The present invention relates to the technical field of PCB packaging, and particularly to an automatic edge wrapping device for PCB boards. Background Art

[0002] The edge wrapping process of PCB boards is one of the important steps in PCB board production. It protects the edges of PCB boards by edge wrapping to increase the mechanical strength of PCB boards and prevent edge delamination and damage. At present, the edge wrapping device has realized the automation of the PCB board edge wrapping process. The specific steps are as follows: Use a vertical plate to rotate the tape wheel three-dimensionally to attach the tape to the edge of the PCB board, use a conveying device to transfer the PCB board under the pressure roller, compact the tape by the pressure roller, and finally use a cutting blade to cut the tape, thus completing the edge wrapping process of the PCB board.

Refer to Figure 1 , Figure 2 and Figure 3 as shown, including: a bottom plate 101; a first mounting seat 102 fixedly installed at the rear of the bottom plate 101; an edge wrapping mechanism arranged on the first mounting seat 102, and the edge wrapping mechanism is used to wrap the tape around the edge of the PCB board; The edge wrapping mechanism includes: a mounting box 201 slidably installed on the front side of the first mounting seat 102, and the mounting box 201 moves back and forth; a first electric rod 202 fixedly installed at the rear of the first mounting seat 102, and the rod of the first electric rod 202 is fixed to the mounting box 201 to drive its movement; two rotating shafts 203 rotatably installed on the front side of the mounting box 201, and the two rotating shafts 203 are distributed up and down; pressing plates 204 respectively rotatably installed on the two rotating shafts 203, an adsorption device is arranged in the pressing plate 204, a hole 212 is arranged on the front side of the pressing plate 204, and the pressing plate 204 can adsorb and fix the tape on its front side through the adsorption device and the hole 212; rollers 205 respectively rotatably installed on the front parts of the two pressing plates 204, and the rollers 205 will contact the PCB board; a moving plate 206 slidably installed on the front side of the mounting box 201, and the moving plate 206 is arranged between the two pressing plates 204; a first spring 207 arranged on the moving plate 206, and the two ends of the first spring 207 are respectively fixed to the moving plate 206 and the mounting box 201, and three groups of first springs 207 are arranged; top blocks 208 fixedly installed on both sides of the upper and lower surfaces of the moving plate 206, and an inclined contact surface is arranged on the top block 208, and the contact surface is lower at the rear and higher at the front; abutting rods 209 fixedly installed on the left and right sides of the two rotating shafts 203, and the abutting rods 209 abut against the contact surface of the top block 208, and a roller is arranged at the end of the abutting rod 209 to enable the abutting rod 209 to contact the top block 208 smoothly; first torsion springs 210 arranged on the left and right sides of the two rotating shafts 203, and the two ends of the first torsion springs 210 are respectively fixed to the pressing plate 204 and the rotating shaft 203; second torsion springs 211 arranged on the left and right sides of the two rotating shafts 203, and the two ends of the second torsion springs 211 are respectively fixed to the rotating shaft 203 and the mounting box 201.

[0029] The adsorption device in the pressing plate 204 is started to adsorb and fix the tape on the front side of the pressing plate 204, and the PCB board is fixed in front of the pressing plate 204. The first electric rod 202 is started to control the installation box 201 to move forward and move toward the PCB board; then the PCB board contacts the moving plate 206 through the tape, and the installation box 201 continues to move forward. The moving plate 206 is squeezed by the PCB board and retracted into the installation box 201, and the first spring 207 is compressed. At the same time, the moving plate 206 moves, which will squeeze the top block 208. The rod 209 is pressed to control the rotation of the rotating shaft 203 and the pressure plate 204. The second torsion spring 211 is twisted, pressing the pressure plate 204 toward the PCB board. The roller 205 rolls in contact with the PCB board and the tape, wrapping and compacting the tape on the upper and lower sides of the edge of the PCB board, completing the automatic edge wrapping process of the PCB board, which is efficient and convenient.

[0030] After the pressure plate 204 is rotated to contact the PCB board, due to the different thicknesses of different PCB boards, the pressure plate 204 can be adjusted to adaptively contact the PCB board by using the first torsion spring 210 to prevent the pressure plate 204 and the PCB board from being damaged due to excessive contact. Therefore, the device can be applied to various types of PCB boards, thereby improving the scope of application of the device.

[0031] See also Figure 1 , Figure 4 and Figure 5 As shown, it also includes: a second mounting seat 103 fixedly mounted on the front of the base plate 101; a clamping mechanism arranged on the second mounting seat 103, the clamping mechanism is used to fix the PCB board and control its rotation to perform reversing; The clamping mechanism includes: moving seats 301 slidably mounted on the left and right sides of the second mounting seat 103 respectively; rotating seats 302 rotatably mounted on the two moving seats 301 respectively; two clamping plates 303 rotatably mounted on the two rotating seats 302 respectively, and the two clamping plates 303 on the left and right sides respectively clamp and fix the left and right sides of the PCB board; third torsion springs 304 provided on the clamping plates 303, with both ends of the third torsion springs 304 fixed to the clamping plates 303 and the rotating seats 302 respectively; a first motor 305 fixedly mounted on the right moving seat 301, and the first motor 305 is fixed to the right rotating seat 302 to drive its rotation; first screw rods 306 rotatably mounted on the left and right sides of the second mounting seat 103, and the first screw rods 306 on both sides are threadedly mounted with the moving seats 301 on both sides respectively, and the forward and reverse rotation of the first screw rods 306 controls the up and down movement of the moving seats 301; a synchronous belt group 307 provided between the first screw rods 306, and the synchronous belt group 307 enables all the screw rods to rotate synchronously; a second motor 310 fixedly mounted on the bottom plate 101, and the second motor 310 is fixed to the first screw rod 306 at the right rear; extrusion blocks 308 fixedly mounted on the left and right sides of the second mounting seat 103; control blocks 309 fixedly mounted on each clamping plate 303, and when the moving seat 301 moves, the control block 309 will contact the extrusion block 308 to rotate the clamping plate 303 to separate the two clamping plates 303 on the same side.

[0032] Refer to Figure 1 As shown, it further includes: a limit frame 601 fixedly mounted on the second mounting seat 103, and the limit frame 601 is arranged on the upper front side of the clamping plate 303.

[0033] Start the second motor 310 to control the rotation of the first screw rod 306, and control the two moving seats 301 to move upward synchronously. Among the clamping plates 303 on the left and right sides, the control block 309 on the clamping plate 303 in the upper position contacts the extrusion block 308, causing the clamping plate 303 to be controlled to rotate and the third torsion spring 304 to be twisted. Therefore, the two clamping plates 303 on the same side are separated from each other. Place the PCB board between the four clamping plates 303 and abut the PCB board against the limit frame 601 for position positioning. After completion, control the first screw rod 306 to reverse, move the moving seat 301 downward, separate the control block 309 from the extrusion block 308, and the third torsion spring 304 restores deformation to control the two clamping plates 303 on the same side to clamp and fix the PCB board; if the two sides of the PCB board need to be edge-bonded, when one side of the PCB board has completed the edge-bonding process, the first motor 305 can be started to control the rotation of the rotating seat 302 to flip the PCB board by 180 degrees, and then the other side of the PCB board can be edge-bonded.

[0034] Refer to Figure 1 、 Figure 6 and Figure 7As shown, it further includes a matching mechanism disposed on the second mounting base 103. The matching mechanism is used to cooperate with the edge wrapping mechanism to improve the edge wrapping effect of the edge wrapping mechanism on the PCB board. The matching mechanism includes: a top bar 401 slidably mounted on the second mounting base 103, and the top bar 401 is disposed on the front side of the clamping plate 303; pull rods 402 slidably mounted on the left and right sides of the second mounting base 103, and the pull rods 402 are fixed to the left and right ends of the top bar 401; a second spring 403 disposed on the pull rods 402, and the two ends of the second spring 403 are respectively fixed to the pull rods 402 and the second mounting base 103; swing arms 404 rotatably mounted on the left and right sides of the second mounting base 103; telescopic ends 405 respectively slidably mounted on the upper ends of the two swing arms 404, and the upper ends of the two telescopic ends 405 are respectively rotatably mounted to the rear ends of the two pull rods 402; ejector rods 406 slidably mounted on the left and right sides of the second mounting base 103, the rear ends of the two ejector rods 406 are respectively fixed to the left and right sides of the mounting box 201, and the front ends of the two ejector rods 406 are respectively in contact with the lower ends of the two swing arms 404. The movement of the ejector rods 406 will control the reverse movement of the pull rods 402 through the swing arms 404.

[0035] During the forward movement of the mounting box 201, the mounting box 201 drives the ejector rods 406 to move forward. The ejector rods 406 will contact the lower ends of the swing arms 404 to control the rotation of the swing arms 404. The upper ends of the swing arms 404 pull the pull rods 402 and the top bar 401 backward through the telescopic ends 405. At the same time, the telescopic ends 405 slide relative to the swing arms 404, and the second spring 403 is compressed, so that the top bar 401 can abut against the front side of the PCB board. Subsequently, the bottom end of the swing arm 404 moves to the upper side of the ejector rod 406, thereby restricting the rotation of the swing arm 404. In order to reduce the friction between the swing arm 404 and the ejector rod 406, rollers can be provided at the bottom end of the swing arm 404. In this way, when the edge wrapping mechanism wraps the edge of the PCB board, the PCB board will not be pushed forward by the edge wrapping mechanism, enabling the edge wrapping mechanism to more accurately perform edge wrapping processing on the PCB board, improving the edge wrapping quality, and preventing the PCB board from moving relative to the clamping plate 303, thereby preventing the PCB board from being scratched and damaged by the clamping plate 303; when the mounting box 201 moves backward and returns to its original position, the ejector rods 406 are separated from the lower ends of the swing arms 404, and the second spring 403 moves the top bar 401 forward to return to its original position.

[0036] Refer to Figure 1 、 Figure 8 and Figure 9 As shown, it further includes: a third mounting base 104 fixedly mounted on the bottom plate 101, and the third mounting base 104 is disposed between the first mounting base 102 and the second mounting base 103; a gluing mechanism disposed on the third mounting base 104, and the gluing mechanism is used for cutting the tape and transferring the tape to the pressing plate 204. The gluing mechanism includes: an adsorption plate 501 rotatably mounted on the third mounting seat 104, which is used to adsorb, fix and transfer the tape. When the adsorption plate 501 rotates to a vertical state, it will contact the front sides of the two pressing plates 204; a fourth motor 508 fixedly mounted on the third mounting seat 104, and the output end of the fourth motor 508 is fixed to the rotating shaft of the adsorption plate 501; a fixing member 502 provided on the third mounting seat 104, which is used to fix the tape. There are two groups of fixing members 502. One group is fixed on the third mounting seat 104 on the right side, and the other group is slidably arranged on the third mounting seat 104 on the left side; a second screw rod 503 rotatably mounted on the third mounting seat 104, and the second screw rod 503 is threadedly installed with the fixing member 502 on the left side; a third motor 504 fixedly mounted on the third mounting seat 104, and the output end of the third motor 504 is fixed to the second screw rod 503; an electric knife 505 rotatably mounted on the right front side of the third mounting seat 104, and the electric knife 505 can automatically rotate to cut the tape; a support plate 506 slidably mounted on the third mounting seat 104, which is arranged below the fixing member 502 on the right side and can contact the fixing member 502 on the left side; a third spring 507 fixedly mounted between the third mounting seat 104 and the support plate 506.

[0037] The fixing member 502 includes: a clamping frame 5021 fixedly / slidably mounted on the third mounting seat 104; a clamping plate 5022 slidably mounted on the clamping frame 5021; a second electric rod 5023 fixedly mounted on the top of the clamping frame 5021, and the rod of the second electric rod 5023 is fixed to the clamping plate 5022 to drive the clamping plate 5022 to move up and down in cooperation with the clamping frame 5021 to clamp and fix the tape.

[0038] In the gluing mechanism, the adsorption plate 501, the support plate 506, the clamping plate 5022 and the clamping frame 5021 are all made of non-stick glue material.

[0039] Pull out the end of the tape roll and pass it through the two fixing members 502. First, control the left fixing member 502 to clamp the tape. Start the third motor 504, control the left fixing member 502 to move the tape to the left and pull the tape out of the tape roll. Then, control the right fixing member 502 to fix the tape, control the electric knife 505 to rotate to cut the tape. After that, control the left fixing member 502 to release the tape and move it to the leftmost side of the third mounting seat 104 and leave from above the adsorption plate 501, so that the cut tape falls on the adsorption plate 501, and control the adsorption plate 501 to adsorb and fix it. At the same time, the new end of the tape is located on the support plate 506 and is fixed by the right fixing member 502. After completing the above tape cutting work, start the fourth motor 508, control the adsorption plate 501 to rotate, move the tape to the front side of the pressing plate 204, control the adsorption device in the pressing plate 204 to start, and then control the adsorption plate 501 to close, that is, transfer the tape to the edge wrapping mechanism to realize automatic feeding of the tape. After completion, control the adsorption plate 501 to turn back, move the left fixing member 502 to the right to return to its position. During the process, the left fixing member 502 contacts the support plate 506 and retracts the support plate 506 to the right under the right fixing member 502. The third spring 507 is compressed, and the end of the tape on the support plate 506 is guided through the left fixing member 502. Therefore, control the left fixing member 502 to fix the end of the tape, control the right fixing member 502 to release the tape, and when moving the left fixing member 502 next time, the tape can be pulled out, and the support plate 506 will be released by the third spring 507 after the left fixing member 502 moves to the left.

Control the gluing mechanism to feed the tape onto the edge wrapping mechanism. 2. Control the moving seat 301 to move upward, open the clamping plate 303, and the auxiliary limit frame 601 places the PCB board on the clamping plate 303. Control the moving seat 301 to move downward to fix the PCB board. At this time, the PCB board and the edge wrapping mechanism are at the same horizontal height. 3. Drive the first electric rod 202, control the pressing plate 204 to move forward, and at the same time control the top bar 401 to move backward and press against the front part of the PCB board to prevent the position of the PCB board from shifting.
