Description
Technical Field
[0001] The present invention relates to the technical field of bonding equipment, and in particular to OCA bonding equipment. Background Art
[0002] OCA optical adhesive is one of the important raw materials for touch screens. It is made by making optical acrylic adhesive without substrate, and then laminating a layer of release film on the upper and lower bottom layers. It is a double-sided laminating tape without substrate material. It is the best adhesive for touch screens. Its advantages are clarity, high light transmittance (total light transmittance 99%), high adhesion, high weather resistance, water resistance, high temperature resistance, UV resistance, controlled thickness, uniform spacing, and no yellowing (yellowing), peeling and deterioration problems after long-term use. When making the display screen of electronic equipment, it is necessary to laminate the glass and the module. One of the solutions is to use OCA. CA optical glue fully bonds the glass to the module. In order to adapt to this production process, it is necessary to develop OCA bonding equipment to improve production efficiency. OCA bonding machine, also known as "vacuum bonding machine" or "touch screen bonding machine", is an industrial automation product controlled by PLC or single-chip microcomputer. It is one of the equipment used for bonding electronic device screens. The bonding principle is to place the LCD screen and glass cover of the electronic device in a vacuum box in a vacuum environment, and use the cylinder pressure of the machine to lower the inner mold of the vacuum cylinder, so that the glass cover and LCD screen placed on the lower mold of the vacuum cylinder are completely pressed together, thereby completing the key process in the repair of electronic device screens.
[0003] When existing small electronic equipment repair shops perform OCA bonding on electronic devices, the electronic equipment is clamped on a mold and the mold is manually fixed to the placement table of the bonding machine through a latch. Different sizes of electronic devices need to be bonded, and molds of different sizes need to be used, so the mold fixing device also needs to be manually changed accordingly, which takes a certain amount of time for the repair personnel, increases the operation steps, reduces work efficiency, and further affects the work experience.
[0004] To this end, an OCA bonding device is proposed. Summary of the invention
[0005] In view of the deficiencies in the prior art, the present invention provides an OCA bonding device.
[0006] To achieve the above object, the present invention provides the following technical solutions:
[0007] OCA bonding equipment, including:
[0008] A laminating machine body, wherein a control panel, two instrument panels and two control buttons are arranged on the top of the laminating machine body, and the two instrument panels and the two control buttons are respectively located on both sides of the control panel;

[0010] Two first threaded strips are symmetrically fixedly installed on the outer walls at both ends of the first transmission shaft, first movable rings adapted to the first threaded strips are symmetrically sleeved on the outer walls at both ends of the first transmission shaft, and a first clamping plate is fixedly connected to the top of the first movable ring, two second threaded strips are symmetrically fixedly installed on the outer walls at both ends of the second transmission shaft, second movable rings adapted to the second threaded strips are symmetrically sleeved on the outer walls at both ends of the second transmission shaft, and a second clamping plate is fixedly connected to the top of the second movable ring;
[0011] A first motor is fixedly installed on the side wall of the supporting platform, and the output end of the first motor is fixedly connected to the central axis of the first transmission shaft, and a second bevel gear is fixedly connected to the middle position of the first transmission shaft. A first bevel gear meshing with the second bevel gear is rotatably installed on the side wall of the supporting platform, a first spur gear is sleeved on the central axis of the first bevel gear, and a second spur gear meshing with the first spur gear is fixedly installed on the second transmission shaft, the diameter of the first bevel gear is the same as the diameter of the second bevel gear, and the diameter of the first spur gear is larger than the diameter of the second spur gear.
[0012] Preferably, the first clamping plate and the second clamping plate both extend to the inner wall of the placement groove, and the first clamping plate and the second clamping plate are both embedded in the supporting platform, and pressure sensors are provided on the inner walls of the first clamping plate and the second clamping plate.
[0013] Preferably, the pressure sensor on the first clamping plate is electrically connected to the control panel and the first motor.
[0014] Through the above scheme, when the staff places the mold with the electronic device and OCA in the placement groove on the carrier table, the first motor is started at this time, and the first motor can drive the first transmission shaft to rotate in the first movable opening groove. At this time, the first movable rings on both sides of the first transmission shaft can slide along the first thread strip to the middle position of the first movable opening groove, and can clamp and fix the front and rear side walls of the mold. In the process of rotation of the first transmission shaft, the second bevel gear can rotate at the same time. At this time, the first bevel gear meshed with the second bevel gear can rotate synchronously and drive the first spur gear to rotate. At this time, the second spur gear meshed with the first spur gear can drive the second transmission shaft to rotate. At this time, the second movable rings on both sides of the second transmission shaft can drive the second clamping plate along the second thread strip to the second movable opening groove and slides at the center of the mold to clamp the two side walls of the mold. Since the diameter of the second spur gear is smaller than that of the first spur gear, the rotation speed of the second transmission shaft is greater than that of the first transmission shaft at this time, so the two side walls of the mold can be quickly clamped first. After the first clamping plate with a slower moving speed contacts the front and rear sides of the mold, the pressure sensor on the first clamping plate can send a signal to cut off the power of the first motor. By driving the pressure sensor in conjunction with the first motor, molds of different diameters can be clamped, which is convenient for OCA bonding of electronic devices of different sizes, can improve applicability, can quickly fix the mold, can ensure the stability of the electronic equipment during the bonding process, and at the same time can improve the clamping efficiency of the mold, and further improve the OCA bonding efficiency of the electronic equipment.
[0015] Preferably, a clutch assembly is also provided in the supporting platform, and the clutch assembly includes an air pump arranged in the supporting platform, and a connector is rotatably installed on the output end of the air pump. The pressure sensor on the second clamping plate is electrically connected to the air pump, and the center of the connector is located on the same axis as the center axis of the first spur gear.
[0016] Preferably, a limiting groove is provided on the central axis of the first spur gear and the central axis of the first bevel gear, and a limiting block matched with the limiting groove is fixedly mounted on the connecting head.
[0017] Through the above scheme, when the air pump is extended, the air pump can push the connecting head to slide toward the first spur gear. At this time, the upper limit block of the connecting head can be embedded in the limit groove. At this time, the central axes of the first spur gear and the first bevel gear are fixed to each other, and because the connecting head is rotatably installed at the output end of the air pump, the first spur gear and the first bevel gear can be guaranteed to rotate normally during the transmission process. When the second clamping plate with a faster moving speed first contacts the two side walls of the mold on the supporting platform, the pressure sensor on the second clamping plate sends a signal to shrink the air pump, so that the limit block on the connecting head can slide out of the limit groove, the first bevel gear and the second bevel gear can be separated from each other, and the second transmission shaft can be quickly stopped from rotating. By controlling the extension and shortening of the air pump, the rotation control of the second transmission shaft can be quickly realized. After clamping and fixing the two side walls of the mold first, the front and back sides of the mold can continue to be clamped, which is beneficial to the clamping and fixing of different molds.
[0018] Preferably, a hydraulic telescopic rod electrically connected to the control panel is fixedly installed on the top of the bonding cabin, and the extended end of the hydraulic telescopic rod is fixedly connected to a pressing platform. Limit rods are symmetrically fixedly installed on both ends of the bonding cabin, and the pressing platform is sleeved on the outside of the limit rods. A vacuum pump electrically connected to the control panel and the instrument panel is fixedly installed on the top of the pressing platform, and a groove is provided at the bottom end of the pressing platform. Two vacuum tubes are fixedly connected to the vacuum pump, and the other ends of the vacuum tubes extend to the two side walls of the groove.
[0019] Preferably, eight pressing rollers are symmetrically installed in the groove for rotation, the central axes of the four pressing rollers on the same side extend to the outside of the pressing platform and are fixedly connected to sprockets, the outer sides of the sprockets on the four pressing rollers on the same side are jointly sleeved with chains, the central axes of the two sprockets in the middle of the groove are respectively fixedly connected with meshing driving gears and driven gears, a third motor electrically connected to the control panel is also fixedly installed on the side wall of the pressing platform, and the output end of the third motor is fixedly connected to the central axis of the driving gear.
[0020] Through the above scheme, the hydraulic telescopic rod can push the pressing platform to slide toward the supporting platform, and the limit rod can ensure the fitting accuracy of the pressing platform and the supporting platform. When the pressing platform and the supporting platform are fitted, the vacuum pump cooperates with the vacuum tube to vacuum the fitting place between the supporting platform and the pressing platform, so as to suck out the air between the electronic device and the OCA, thereby ensuring the fitting effect. During the fitting process, when the third motor is energized to drive the driving gear to rotate counterclockwise, the driven gear meshing with the driving gear can rotate clockwise, so that the pressing roller on the same side can rotate in the groove with the corresponding sprocket and chain. During the rotation of the pressing roller, the pressing roller can squeeze the air in the middle position of the fitting place between the electronic device and the OCA to both sides of the electronic device, so that the air can flow to the vacuum tube, thereby improving the vacuum effect, and further improving the fitting effect of the OCA.
[0021] Preferably, a slide groove matched with the slide rail is opened at the bottom end of the supporting platform, a second motor electrically connected to the control panel is fixedly installed at the bottom end of the laminating machine body, and the output end of the second motor is fixedly connected to the first pulley.
[0022] Preferably, a threaded screw is rotatably installed at the center of the bottom end of the fitting cabin, a second pulley is fixedly connected to the central axis of the threaded screw, a transmission belt is commonly sleeved on the outer side of the second pulley and the first pulley, and a threaded hole matching the threaded screw is opened at the bottom end of the support platform.
[0023] Through the above scheme, during use, when the second motor is energized, the first pulley at the output end of the second motor can drive the second pulley to rotate through the transmission belt, and the second pulley can drive the threaded screw to rotate in the bonding cabin. Since a threaded hole compatible with the threaded screw is provided on the supporting platform, the supporting platform can slide along the slide rail through the threaded hole in cooperation with the threaded screw, and by controlling the rotation direction of the second motor, the rotation direction of the threaded screw can be controlled, and the sliding direction of the supporting platform can be further controlled, so that the electronic equipment to be bonded can be moved to the bonding cabin for bonding processing, and the bonded electronic equipment can be quickly and conveniently taken out from the bonding cabin, which can ensure processing efficiency and reduce the operating steps of the staff, further improving the work experience.
[0024] Compared with the prior art, the present invention has the following beneficial effects:
[0025] 1. The present invention starts the first motor, and the first motor can drive the first transmission shaft to rotate in the first movable opening groove. At this time, the first movable rings on both sides of the first transmission shaft can slide along the first thread strip to the middle position of the first movable opening groove, and can clamp and fix the front and rear side walls of the mold. In the process of rotation of the first transmission shaft, the second bevel gear can rotate at the same time. At this time, the first bevel gear meshed with the second bevel gear can rotate synchronously and drive the first spur gear to rotate. At this time, the second spur gear meshed with the first spur gear can drive the second transmission shaft to rotate. At this time, the second movable rings on both sides of the second transmission shaft can drive the second clamping plate to slide along the second thread strip to the center of the second movable opening groove, and can clamp and fix the front and rear side walls of the mold. In addition, during the rotation of the first transmission shaft, the second bevel gear can rotate at the same time. At this time, the first bevel gear meshed with the second bevel gear can rotate synchronously and drive the first spur gear to rotate. At this time, the second spur gear meshed with the first spur gear can drive the second transmission shaft to rotate. At this time, the second movable rings on both sides of the second transmission shaft can drive the second clamping plate to slide along the second thread strip to the center of the second movable opening groove, and can clamp and fix the front and rear side walls of the mold. Clamping, since the diameter of the second spur gear is smaller than that of the first spur gear, the rotation speed of the second transmission shaft is greater than that of the first transmission shaft, so the two side walls of the mold can be clamped quickly first, and after the first clamping plate with a slower moving speed contacts the front and rear sides of the mold, the pressure sensor on the first clamping plate can send a signal to cut off the power of the first motor. By driving the pressure sensor in conjunction with the first motor, molds of different diameters can be clamped, which is convenient for OCA bonding of electronic devices of different sizes, can improve applicability, can quickly fix the mold, can ensure the stability of the electronic equipment during the bonding process, and at the same time can improve the clamping efficiency of the mold, and further improve the OCA bonding efficiency of the electronic equipment.
[0026] 2. According to the present invention, when the air pump is extended, the air pump can push the connecting head to slide toward the first spur gear. At this time, the upper limit block of the connecting head can be embedded in the limit groove. At this time, the central axes of the first spur gear and the first bevel gear are fixed to each other, and because the connecting head is rotatably installed at the output end of the air pump, it can ensure that the first spur gear and the first bevel gear rotate normally during the transmission process. When the second clamping plate with a faster moving speed first contacts the two side walls of the mold on the supporting platform, the pressure sensor on the second clamping plate sends a signal to shrink the air pump, so that the limit block on the connecting head can slide out of the limit groove, the first bevel gear and the second bevel gear can be separated from each other, and the second transmission shaft can be quickly stopped from rotating. By controlling the extension and shortening of the air pump, the rotation control of the second transmission shaft can be quickly realized. After first clamping and fixing the two side walls of the mold, the front and back sides of the mold can continue to be clamped, which is beneficial to the clamping and fixing of different molds.
[0027] 3. The present invention can push the pressing platform to slide toward the supporting platform through the hydraulic telescopic rod, and the limit rod can ensure the fitting accuracy between the pressing platform and the supporting platform. When the pressing platform and the supporting platform are fitted, the vacuum pump cooperates with the vacuum tube to vacuum the fitting place between the supporting platform and the pressing platform, so as to suck out the air between the electronic device and the OCA, thereby ensuring the fitting effect. In the fitting process, when the third motor is energized to drive the driving gear to rotate counterclockwise, the driven gear meshing with the driving gear can rotate clockwise, so that the pressing roller on the same side can rotate in the groove with the corresponding sprocket and chain. In the process of rotation of the pressing roller, the pressing roller can squeeze the air in the middle position of the fitting place between the electronic device and the OCA to both sides of the electronic device, so that the air can flow to the vacuum tube, thereby improving the vacuum effect, and further improving the fitting effect of the OCA.

The adaptive clamping assembly includes a first movable opening groove 30 and a second movable opening groove 31 provided on the carrying platform 7. The first movable opening groove 30 and the second movable opening groove 31 are arranged perpendicular to each other, and the first movable opening groove 30 is located above the second movable opening groove 31. A first transmission shaft 13 is spirally installed in the first movable opening groove 30, and a second transmission shaft 37 is spirally installed in the second movable opening groove 31.
[0044] Two first threaded strips 45 are symmetrically fixedly installed on the outer walls at both ends of the first transmission shaft 13, and first movable rings 46 adapted to the first threaded strips 45 are symmetrically sleeved on the outer walls at both ends of the first transmission shaft 13. The top of the first movable ring 46 is fixedly connected to a first clamping plate 47, and two second threaded strips 38 are symmetrically fixedly installed on the outer walls at both ends of the second transmission shaft 37. Second movable rings 39 adapted to the second threaded strips 38 are symmetrically sleeved on the outer walls at both ends of the second transmission shaft 37, and the top of the second movable ring 39 is fixedly connected to a second clamping plate 40;
[0045] A first motor 8 is fixedly mounted on the side wall of the supporting platform 7, and the output end of the first motor 8 is fixedly connected to the central axis of the first transmission shaft 13, and a second bevel gear 44 is fixedly connected to the middle position of the first transmission shaft 13. A first bevel gear 43 meshing with the second bevel gear 44 is rotatably mounted on the side wall of the supporting platform 7, a first spur gear 33 is sleeved on the central axis of the first bevel gear 43, and a second spur gear 35 meshing with the first spur gear 33 is fixedly mounted on the second transmission shaft 37, the diameter of the first bevel gear 43 is the same as the diameter of the second bevel gear 44, and the diameter of the first spur gear 33 is larger than the diameter of the second spur gear 35.
[0046] The first clamping plate 47 and the second clamping plate 40 both extend to the inner wall of the placement groove 32 , and are both embedded in the support platform 7 . Pressure sensors 41 are disposed on the inner walls of the first clamping plate 47 and the second clamping plate 40 .
[0047] The pressure sensor 41 on the first clamping plate 47 is electrically connected to the control panel 2 and the first motor 8 .
[0048] In the present embodiment, during use, after the staff has placed the mold with the electronic device and the OCA in the placement groove 32 on the carrier 7, the first motor 8 is started, and the first motor 8 can drive the first transmission shaft 13 to rotate in the first movable opening groove 30. At this time, the first movable rings 46 on both sides of the first transmission shaft 13 can slide along the first threaded strip 45 to the middle position of the first movable opening groove 30, and can clamp and fix the front and rear side walls of the mold. In the process of rotation of the first transmission shaft 13, the second bevel gear 44 can rotate at the same time. At this time, the first bevel gear 43 meshing with the second bevel gear 44 can rotate synchronously and drive the first spur gear 33 to rotate. At this time, the second spur gear 35 meshing with the first spur gear 33 can drive the second transmission shaft 37 to rotate. At this time, the second movable rings 39 on both sides of the second transmission shaft 37 can drive the second clamping plate 40 to rotate along the second threaded strip 45. The stripes 38 slide toward the center of the second movable opening groove 31, and can clamp the two side walls of the mold.

[0050] A limiting groove 34 is formed on the central axis of the first spur gear 33 and the central axis of the first bevel gear 43 , and a limiting block 25 matched with the limiting groove 34 is fixedly mounted on the connector 42 .
[0051] In this embodiment, when in use, after the air pump 36 is extended, the air pump 36 can push the connector 42 to slide toward the first spur gear 33. At this time, the upper limit block 25 of the connector 42 can be embedded in the limit groove 34. At this time, the central axes of the first spur gear 33 and the first bevel gear 43 are fixed to each other, and because the connector 42 is rotatably mounted on the output end of the air pump 36, it can ensure that the first spur gear 33 and the first bevel gear 43 rotate normally during the transmission process. When the second clamping plate 40 with a faster moving speed first contacts the two side walls of the mold on the carrier 7 After the touch, the pressure sensor 41 on the second clamping plate 40 sends a signal to shrink the air pump 36, so that the limit block 25 on the connecting head 42 can slide out of the limit groove 34, so that the first bevel gear 43 and the second bevel gear 44 can be separated from each other, and the second transmission shaft 37 can be quickly stopped from rotating. By controlling the extension and shortening of the air pump 36, the rotation control of the second transmission shaft 37 can be quickly realized. After clamping and fixing the two side walls of the mold first, the front and rear sides of the mold can continue to be clamped, which is beneficial to the clamping and fixing of different molds.

Limit rods 5 are symmetrically fixedly installed on both ends of the bonding cabin 6. The pressing platform 11 is sleeved on the outside of the limit rod 5. A vacuum pump 12 electrically connected to the control panel 2 and the instrument panel 3 is fixedly installed on the top of the pressing platform 11. A groove 23 is provided at the bottom end of the pressing platform 11. Two vacuum pipes 17 are fixedly connected to the vacuum pump 12, and the other end of the vacuum pipe 17 extends to the two side walls of the groove 23.
[0053] Eight pressing rollers 15 are symmetrically installed in the groove 23 for rotation. The central axes of the four pressing rollers 15 on the same side extend to the outside of the pressing table 11 and are fixedly connected to a sprocket 21. The outer sides of the sprockets 21 on the four pressing rollers 15 on the same side are jointly sleeved with a chain 22. The central axes of the two sprockets 21 in the middle of the groove 23 are respectively fixedly connected to a meshing driving gear 19 and a driven gear 18. A third motor 20 electrically connected to the control panel 2 is also fixedly installed on the side wall of the pressing table 11, and the output end of the third motor 20 is fixedly connected to the central axis of the driving gear 19.
[0054] In this embodiment, when in use, the hydraulic telescopic rod 16 can push the pressing platform 11 to slide toward the bearing platform 7, and the limiting rod 5 can ensure the fitting accuracy of the pressing platform 11 and the bearing platform 7. When the pressing platform 11 and the bearing platform 7 are fitted together, the vacuum pump 12 cooperates with the vacuum tube 17 to vacuum the fitting place between the bearing platform 7 and the pressing platform 11, so as to suck out the air between the electronic device and the OCA, thereby ensuring the fitting effect. In the fitting process, when the third motor 20 is energized to drive the driving gear 19 to rotate counterclockwise, the driven gear 18 meshing with the driving gear 19 can rotate clockwise, so that the pressing roller 15 on the same side can rotate in the groove 23 with the corresponding sprocket 21 and the chain 22. In the process of the rotation of the pressing roller 15, the pressing roller 15 can squeeze the air in the middle position of the fitting place between the electronic device and the OCA to both sides of the electronic device, so that the air can flow to the vacuum tube 17, thereby improving the vacuum effect, and further improving the fitting effect of the OCA.

[0056] A threaded screw 10 is rotatably installed at the center of the bottom end of the fitting cabin 6, and a second pulley 27 is fixedly connected to the central axis of the threaded screw 10. A transmission belt 26 is jointly sleeved on the outer side of the second pulley 27 and the first pulley 24, and a threaded hole 28 compatible with the threaded screw 10 is opened at the bottom end of the supporting platform 7.
[0057] In this embodiment, when the second motor 14 is energized, the first pulley 24 at the output end of the second motor 14 can drive the second pulley 27 to rotate through the transmission belt 26. At this time, the second pulley 27 can drive the threaded screw 10 to rotate in the bonding cabin 6. Since a threaded hole 28 compatible with the threaded screw 10 is provided on the supporting platform 7, the supporting platform 7 can slide along the slide rail 9 through the threaded hole 28 in cooperation with the threaded screw 10. By controlling the rotation direction of the second motor 14, the rotation direction of the threaded screw 10 can be controlled, and the sliding direction of the supporting platform 7 can be further controlled, so that the electronic equipment to be bonded can be moved to the bonding cabin 6 for bonding processing, and the bonded electronic equipment can be quickly and conveniently taken out from the bonding cabin 6, which can ensure processing efficiency and reduce the operating steps of the staff, thereby further improving the work experience.
[0058] Working principle: First, open the laminating machine body 1, clamp the cleaned electronic device on the mold and stick the OCA, then place the mold directly in the placement slot 32 on the carrier 7, and then the control panel 2 cooperates with the control button 4 to start the first motor 8, and the first motor 8 can drive the first transmission shaft 13 to rotate in the first movable opening slot 30. At this time, the first movable rings 46 on both sides of the first transmission shaft 13 can slide along the first threaded strip 45 to the middle position of the first movable opening slot 30, and can clamp and fix the front and rear side walls of the mold, and during the rotation of the first transmission shaft 13, the second bevel gear 44 can rotate at the same time, and the first bevel gear 43 meshing with the second bevel gear 44 can rotate synchronously and drive the first spur gear 33 to rotate, and the second spur gear 35 meshing with the first spur gear 33 can drive the second transmission shaft 37 to rotate, and the second movable rings 39 on both sides of the second transmission shaft 37 can drive The movable second clamping plate 40 slides along the second threaded strip 38 toward the center of the second movable opening groove 31, and can clamp the two side walls of the mold. Since the diameter of the second spur gear 35 is smaller than the diameter of the first spur gear 33, the rotation speed of the second transmission shaft 37 is greater than the rotation speed of the first transmission shaft 13 at this time, and the two side walls of the mold can be quickly clamped first. After the first clamping plate 47 with a slower moving speed contacts the front and rear sides of the mold, the pressure sensor 41 on the first clamping plate 47 can send a signal to cut off the power of the first motor 8. The pressure sensor 41 cooperates with the first motor 8 to drive, so that molds of different diameters can be clamped, which is convenient for OCA bonding of electronic devices of different sizes, can improve applicability, can quickly fix the mold, can ensure the stability of the electronic device during the bonding process, and can improve the clamping efficiency of the mold, and further improve the OCA bonding efficiency of the electronic device.
[0059] In the process of fixing the mold, when the air pump 36 is extended, the air pump 36 can push the connecting head 42 to slide toward the first spur gear 33. At this time, the upper limit block 25 of the connecting head 42 can be embedded in the limit groove 34. At this time, the central axes of the first spur gear 33 and the first bevel gear 43 are fixed to each other, and because the connecting head 42 is rotatably installed at the output end of the air pump 36, it can ensure that the first spur gear 33 and the first bevel gear 43 rotate normally during the transmission process. When the second clamping plate 40 with a faster moving speed first contacts the two side walls of the mold on the supporting platform 7 After that, the pressure sensor 41 on the second clamping plate 40 sends a signal to shrink the air pump 36, so that the limit block 25 on the connecting head 42 can slide out of the limit groove 34, so that the first bevel gear 43 and the second bevel gear 44 can be separated from each other, and the second transmission shaft 37 can be quickly stopped from rotating. By controlling the extension and shortening of the air pump 36, the rotation control of the second transmission shaft 37 can be quickly realized, and after clamping and fixing the two side walls of the mold first, the front and rear sides of the mold can continue to be clamped, which is beneficial to the clamping and fixing of different molds.
[0060] After the mold is fixed, the second motor 14 is powered on. At this time, the first pulley 24 at the output end of the second motor 14 can drive the second pulley 27 to rotate through the transmission belt 26. At this time, the second pulley 27 can drive the threaded screw 10 to rotate in the bonding chamber 6. Since the bearing platform 7 is provided with a threaded hole 28 adapted to the threaded screw 10, the bearing platform 7 can slide along the slide rail 9 through the threaded hole 28 and the threaded screw 10, so that the mold is moved to the bottom of the pressing platform 11 to perform vacuum bonding.
[0061] During vacuum bonding, the hydraulic telescopic rod 16 can push the pressing platform 11 to slide toward the supporting platform 7, and the limiting rod 5 can ensure the bonding accuracy of the pressing platform 11 and the supporting platform 7. When the pressing platform 11 and the supporting platform 7 are bonded, the vacuum pump 12 cooperates with the vacuum tube 17 to vacuum the bonding point between the supporting platform 7 and the pressing platform 11, so as to suck out the air between the electronic device and the OCA, thereby ensuring the bonding effect. During the bonding process, when the third motor 20 is energized to drive the driving gear 19 to rotate counterclockwise, the driven gear 18 meshing with the driving gear 19 can rotate clockwise, so that the pressing roller 15 on the same side can rotate in the groove 23 with the corresponding sprocket 21 and the chain 22. During the rotation of the pressing roller 15, the pressing roller 15 can squeeze the air in the middle position of the bonding point between the electronic device and the OCA to both sides of the electronic device, so that the air can flow to the vacuum tube 17, thereby improving the vacuum effect, and further improving the bonding effect of the OCA.
[0062] When in use, by controlling the rotation direction of the second motor 14, the rotation direction of the screw rod 10 can be controlled, and the sliding direction of the support platform 7 can be further controlled, so that the electronic device to be bonded can be moved to the bonding chamber 6 for bonding processing, and the bonded electronic device can be quickly and conveniently removed from the bonding chamber 6, thereby ensuring processing efficiency, reducing the operating steps of the staff, and further improving the work experience.
