Description

Technical Field

[0001] This utility model relates to an attachment platform, specifically a highly versatile ACF attachment platform, belonging to the field of ACF adhesive technology. Background Technology

[0002] ACF adhesive layer is a transparent polymer bonding material developed by Sony. It is formed by uniformly dispersing tiny conductive ions in an adhesive resin. The ACF adhesive layer electrically connects the driver circuit board and the LCD panel substrate, as well as the driver circuit board and the printed circuit board, to achieve electrical conduction.

[0003] A search revealed a Chinese patent (CN217011314U) that discloses an ACF (Acrylic Fluorescent Adhesive) bonding device. The device includes a worktable, a first support frame on one side of the worktable, a wire feeding reel on the upper end of the first support frame, a first guide wheel below the wire feeding reel, two symmetrical second guide wheels on one side of the first guide wheel, a bonding structure on one side of the first support frame, and a pressing structure on the side of the bonding structure away from the first support frame. This bonding device has a simple structure and is easy to operate. Through bonding and pressing, it effectively improves the ACF bonding effect. The nozzle can remove impurities from the ACF adhesive, effectively ensuring the quality of ACF bonding.

[0004] While the above solutions are simple in structure and easy to operate, the worktable in the aforementioned patent is not suitable for printed circuit boards of different specifications and can only perform mounting operations on printed circuit boards of the same specification, which is quite limited and has low practicality. Therefore, we provide a highly versatile ACF mounting platform to solve the above problems. Utility Model Content

[0010] Preferably, the output shaft of the second DC motor is fixedly connected to a linkage column, and a linkage plate is fixedly connected to the outer circumferential surface of the linkage column. The linkage plate can effectively drive the second linkage plate to move.

[0011] Preferably, a second linkage plate is rotatably connected to one side of the first linkage plate, and a suction nozzle mechanism is fixedly connected to one end of the second linkage plate. The suction nozzle mechanism is existing technology and will not be described in detail.

[0025] This utility model provides a highly versatile ACF attachment platform.

[0026] Please see Figure 1 It includes two conveying mechanisms 1 and an attachment platform 2. The two conveying mechanisms 1 are mainly composed of a frame, belt, transmission roller and motor, etc. The motor is not limited and can be replaced by other power sources. The conveying mechanism 1 is existing known technology, so it will not be described in detail in this application.

[0027] Please see Figure 1 , Figure 4 and Figure 5A support plate 11 is fixedly connected to one side of the attachment platform 2, and a control support plate 12 is fixedly connected to one side of the support plate 11. The support plate 11 is positioned so that the control support plate 12 is above the attachment platform 2, which is beneficial for subsequent pick-up and drop operations. A U-shaped bracket 13 is fixedly connected to one side of the control support plate 12. The U-shaped bracket 13 ensures that the DC motor 14 can work stably. The DC motor 14 is fixedly connected to the inner wall of the U-shaped bracket 13, and the output shaft of the DC motor 14 is fixedly connected to the linkage column 15. The purpose of setting the DC motor 14 is to effectively provide sufficient power support for the rotation of the linkage column 15. The DC motor 14 is existing known technology and will not be described in detail.

[0028] Please see Figure 4 and Figure 5 A planar sprocket 21 is fixedly connected to the outer circumference of the linkage column 15. The linkage column 15 and the planar sprocket 21 maintain a linkage effect. There are two planar sprockets 21 in total. Both planar sprockets 21 are engaged with the linkage chain 22. The linkage chain 22 is set so that the two planar sprockets 21 can rotate synchronously, thereby ensuring that the two subsequent suction nozzle mechanisms 18 move synchronously and successfully complete the pick-up and put-down operation.

[0029] Please see Figure 4 Linkage plate 16 is fixedly connected to the outer circumference of linkage column 15. Linkage column 15 and linkage plate 16 maintain linkage. Linkage plate 2 17 is rotatably connected to one side of linkage plate 16. The rotation of linkage plate 16 can drive linkage plate 2 17 to translate. Linkage plate 2 17 is slidably connected to one side of control slider 2 19. The setting of control slider 2 19 can effectively apply control effect to linkage plate 2 17 through its groove, so that linkage plate 2 17 can move up and down stably.

[0030] Please see Figure 4 The other side of the control slider 19 is slidably connected to the other side of the control support plate 12 via the guide rail 20. The tight fit between the control slider 19 and the guide rail 20 ensures that the control slider 19 can slide horizontally without falling off.

[0031] Please see Figure 4One end of the linkage plate 17 is fixedly connected to the suction nozzle mechanism 18. The linkage plate 17 and the suction nozzle mechanism 18 maintain a linkage effect. The suction nozzle mechanism 18 is used to adsorb ACF and printed circuit boards. The suction nozzle mechanism 18 mainly includes a suction nozzle head and an air passage interface. The suction nozzle mechanism 18 is connected to an external vacuum source through the air passage interface. When the vacuum source is started, the air in the air passage is quickly drawn away, and a low-pressure environment is formed inside the suction nozzle head, while the external environment is normal atmospheric pressure. At this time, the pressure difference between atmospheric pressure and the pressure inside the suction nozzle will generate an adsorption force on the material. When the high-speed airflow passes through the suction nozzle head, according to Bernoulli's principle, the air velocity near the suction nozzle head increases, further reducing the local pressure and enhancing the adsorption effect. The suction nozzle mechanism 18 is a known technology and will not be described in detail.

[0032] Please see Figure 2 A DC motor 3 is fixedly connected to the bottom of the attachment platform 2. The output shaft of the DC motor 3 is fixedly connected to a synchronous pulley 4. The DC motor 3 can effectively provide sufficient power support for the rotation of the synchronous pulley 4. The DC motor 3 is a known technology and will not be described in detail.

[0033] Please see Figure 2 The outer circumferential surface of the synchronous pulley 4 is connected to the synchronous belt 5. The synchronous belt 5 enables the two synchronous pulleys 4 to rotate synchronously. The outer circumferential surface of the synchronous pulley 4 is provided with small teeth, and the inner wall of the synchronous belt 5 is provided with tooth grooves, thereby ensuring sufficient friction and preventing slippage. The outer wall of the synchronous belt 5 is fixedly connected to the linkage positioning block 6. The synchronous belt 5 will drive the linkage positioning block 6 to move. There are two linkage positioning blocks 6 in total. Through the reasonable distribution of the two linkage positioning blocks 6, the two linkage positioning blocks 6 move in opposite directions.

[0034] Please see Figure 2 and Figure 3 The top of the linkage positioning block 6 is fixedly connected to the support plate 7, and the bottom of the support plate 7 is fixedly connected to the control slider 9. The linkage positioning block 6, the support plate 7 and the control slider 9 maintain a linkage effect. There are two control sliders 9. The two control sliders 9 are slidably connected to the inner wall of the attachment platform 2 through the guide rails 10. The tight cooperation between the control sliders 9 and the guide rails 10 ensures that the control sliders 9 can only slide horizontally in the specified direction, thereby ensuring that the support plate 7 can move stably.

[0035] Please see Figure 1 , Figure 2 and Figure 3A fixing clamp 8 is fixedly connected to the top of the supporting plate 7. The supporting plate 7 and the fixing clamp 8 maintain a linkage effect. The fixing clamp 8 is slidably connected in the groove opened in the attachment platform 2. The setting of the fixing clamp 8, through its movable design, can be used to accommodate printed circuit boards of different specifications. The attachment platform 2 is fixedly connected between two conveying mechanisms 1. The setting of two conveying mechanisms 1 ensures the stability of the attachment platform 2. It is worth mentioning that the fixing clamp 8 is equipped with a sensor. The sensor is used to detect whether there is a printed circuit board on the attachment platform 2. The sensor is electrically directly connected to DC motor 1 3 and DC motor 2 14 respectively.

[0036] Working Principle: During operation, two conveying mechanisms 1 respectively transport ACF and printed circuit boards. The suction nozzle mechanism 18 adsorbs the printed circuit board. At this time, the DC motor 14 is started to rotate forward, driving the linkage plate 16 to rotate via the linkage column 15. Since the linkage plate 17 is restricted by the control slider 19 to move only up and down, and the control slider 19 is restricted by the guide rail 20 to move only left and right, the linkage plate 16 changes the position of the suction nozzle mechanism 18 through the linkage plate 17. At this time, the suction nozzle mechanism 18 drives the printed circuit board to move in a semi-circular state, thus placing the printed circuit board stably on the attachment platform 2. At this time, the sensor embedded in the fixing fixture 8 starts the DC motor 3 to work, driving the synchronous wheel 4 to rotate in place. Under the action of the synchronous belt 5, the two synchronous wheels 4 rotate stably in place. Due to the reasonable arrangement of the two linkage positioning blocks 6, the movement of the synchronous belt 5 will cause the two linkage positioning blocks 6 to rotate. The two linkage positioning blocks 6 move in opposite directions, causing the support plate 7 to move. At this time, the support plate 7 is restricted by the guide rail 10 through the control slider 9, ensuring the stability of the support plate 7 during movement. This allows the two fixed clamps 8 to hold the printed circuit board. The movable design of the two fixed clamps 8 makes the platform suitable for printed circuit boards of different specifications. Then, the DC motor 14 reverses, causing the suction nozzle mechanism 18 to reset and adsorb the next printed circuit board. The rotation of the linkage column 15 will drive the plane sprocket 21 to rotate. Through the linkage chain 22, the other plane sprocket 21 will rotate, thus causing the other suction nozzle mechanism 18 to move with the adsorbed ACF. Finally, the ACF is placed directly above the printed circuit board. Since there is already a printed circuit board above the attachment platform 2, the other suction nozzle mechanism 18 will drive the ACF to press the printed circuit board, thus allowing the ACF to be attached to the printed circuit board.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
