[0021] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example 1: See Figures 1-6As shown, according to an embodiment of the present invention, there is provided an FPC full-panel gluing device, comprising: a housing 1, within which a circular tube 1 2 and a circular tube 2 3 are mounted for relative rotation; a driving mechanism 4 is provided on one side of the housing for driving the circular tube 1 2 and the circular tube 2 3 to rotate respectively; and an exhaust mechanism 5 is provided on the other side of the housing for extracting gas from the circular tube 1 2 and the circular tube 2 3 respectively; The outer circumferential walls of the circular tube 1 2 and the circular tube 2 3 are respectively provided with a plurality of adsorption holes 1 21 and a plurality of adsorption holes 2 31 at equal intervals, and an arc-shaped plate 9 is provided inside the circular tube 1 2; A filling rod 6 is provided in the corresponding adsorption hole 1 21 for filling the opening of the corresponding adsorption hole; A pressure limiting valve 10 is fixedly installed in the corresponding adsorption hole 2 31; A material storage mechanism 7 is provided on the top side of the circular tube 2 and is used for storing the film raw materials; The feeding mechanism 8 is provided on the bottom plate of the housing 1 and is used to drive the FPC board located at the bottom side of the circular tube 1 2 and the circular tube 2 3 to move back and forth.

[0023] In this embodiment, when the improved FPC full-panel gluing device is used, the housing 1 is fixedly mounted on the corresponding station of the production line by bolts. Figure 1 、 Figure 3 and Figure 8 As shown, first, the FPC is placed in the mounting groove of the feeding mechanism 8, and then the feeding mechanism 8 starts to push the FPC toward the round tube 2 until the head end of the FPC moves to the bottom of the round tube 2; Please refer to Figure 1 and Figure 2 As shown, the driving mechanism 4 drives the circular tube 1 2 and the circular tube 2 3 to rotate toward each other, while the exhaust mechanism 5 continuously extracts the gas in the circular tube 1 2 and the circular tube 2 3; Please refer to Figure 2 、 Figure 3 and Figure 11 As shown, as the gas in the circular tube 2 is lost, the external gas flows into the circular tube 2 through the adsorption hole 21 to replenish the gas lost in the circular tube 2. Since the amount of gas passing through the adsorption hole 21 is limited, a negative pressure cavity of corresponding strength is formed in the circular tube 2. Please refer to Figure 2 、 Figure 3 、 Figure 6 and Figure 11 As shown, as the gas in the second circular tube 3 is lost, a negative pressure chamber of corresponding strength is formed in the second circular tube 3 due to the obstruction of the first pressure limiting valve 10. When a sufficient pressure difference is generated at both ends of the first pressure limiting valve 10, the external gas flows into the second circular tube 3 through the second adsorption hole 31 and the pressure limiting valve to replenish the gas lost in the second circular tube 3. Please refer to Figure 1-Figure 5As shown, as the circular tube 1-2 rotates, when the adsorption hole 1-21 moves to the position of the storage mechanism 7, due to the adsorption of the film raw material by the adsorption hole 1-21, a plurality of films in the storage mechanism 7 are sequentially drawn out from the storage mechanism 7, and the films are adhered to the outer wall of the circular tube 1-2 and rotate with the circular tube 1-2; Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, with the rotation of the circular tube 1 2, the end of the adhesive film is inserted between the circular tube 1 2 and the circular tube 2 3. At this time, the bottom film of the adhesive film is adsorbed on the outer wall of the circular tube 2 3. With the rotation of the circular tube 1 2 and the circular tube 2 3, the bottom film is torn off from the adhesive film, thereby dividing the adhesive film into two parts: the film body and the bottom film. Subsequently, the head end to the tail end of the film body are gradually moved to the bottom end of the circular tube 1 2 by the rotation of the circular tube 1 2. When the film body moves to the bottom end, due to the mutual interference between the filling rod 6 and the arc plate 9, the filling rod 6 can be pushed toward the opening direction of the adsorption hole 1 21 until the filling rod 6 completes the filling of the adsorption hole opening, so as to remove the adsorption force between the bottom end of the bottom circular tube 1 2 and the film body, and at the same time form a complete arc surface at the bottom end of the circular tube 1 2. According to the above, in the process of the circular tube 1-2 moving the end of the film body to the bottom end of the circular tube 1-2, the feeding mechanism 8 is synchronously started and continues to push the FPC, so that the head end and the tail end of the FPC gradually pass through the gap between the bottom end of the circular tube 1-2 and the bottom plate of the shell 1, and finally the film body gradually covers the top side of the FPC. The film body and the head end and the tail end of the FPC can be gradually pressed by the complete arc surface of the bottom end of the circular tube 1-2, so that the film body is firmly bonded to the FPC. At the same time, the bubble removal operation of the scraper is simulated to ensure that there are no bubbles between the film body and the FPC, and finally the gluing operation of the entire FPC film is completed; It should be noted that when the head end of the film moves to the bottom end of the circular tube 2, the film cooperates with the arc plate 9 to complete the blocking of all the adsorption holes 21 on the circular tube 2. At this time, the air pressure inside the circular tube 2 drops rapidly. At this time, the exhaust mechanism 5 stops the gas in the circular tube 2, preventing the circular tube 2 from immediately extracting the second layer of film from the storage mechanism 7 after extracting the first layer of film from the storage mechanism 7, which would affect the subsequent use of the device. Please refer to Figure 1 、 Figure 3 and Figure 6As shown, after the FPC completes the whole-plate gluing operation, the operator directly tears off the bottom film from the circular tube 2 3, and then starts the feeding mechanism 8 to move the FPC in the opposite direction until the FPC is reset. When the tail end of the FPC moves to the gap between the bottom end of the circular tube 2 3 and the bottom plate of the shell 1, due to the adsorption of the adsorption hole 2 31 on the tail end of the film body, the waste material at the tail end of the film body is adsorbed and fixed on the outer wall of the circular tube 2 3. At this time, the exhaust mechanism 5 stops extracting the gas inside the circular tube 2 3. Due to the inflow of external gas into the openings of the adsorption holes 2 31 at other positions, when they are in contact with the film body, no adsorption force is generated on the film body. Therefore, through the resetting movement of the FPC and the rotation of the circular tube 2 3, the waste material of the film body is gradually torn off from the FPC. After the FPC is reset, the waste material is directly torn off from the outer wall of the circular tube 2 3, and finally the whole-plate gluing operation on the FPC is completed. It should be noted that a control host is mounted on the outer wall of the housing 1 for controlling the operation of the device; In summary, the improved FPC whole-plate gluing device only requires the operator to complete the loading of the film raw materials and FPC in the device, and can automatically complete the alignment of the film and FPC, laying and bonding, bubble removal and waste tearing operations. The operation is simple, which greatly improves the efficiency of the FPC whole-plate gluing, and does not require the operator to have a high level of work experience, which facilitates the manufacturing and production of integrated circuits in the factory production line.

[0024] In a further preferred embodiment of the present invention, Figure 3 As shown, the arc plate 9 is set in a semi-circular tube shape and is fixedly connected to the inner wall of the shell 1. The outer arc wall of the arc plate 9 contacts the inner wall of the circular tube 2, and the bottom end side wall thereof is set in an inclined surface shape; In this embodiment, please refer to Figure 3-Figure 5 As shown, as the circular tube 2 rotates, when the filling rod 6 moves to the bottom end of the curved plate 9, due to the mutual interference between the filling rod 6 and the inclined surface of the curved plate 9, the filling rod 6 can be gradually pressed into the adsorption hole 21 along the inclined surface of the curved plate 9, completing the filling of the opening of the adsorption hole 21; when the filling rod 6 moves away from the top end of the filling rod 6, due to the pressure difference between the two ends of the adsorption hole 21, the outside air automatically pushes the filling rod 6 to move in the opposite direction and reset, thereby eliminating the need for an additional driving structure and reducing the production cost of the device; It should be noted that round tube 1 2 , round tube 2 3 , curved plate 9 and filling rod 6 can be made of cemented carbide or aluminum alloy, and the surface is electroplated or polished to form a flat and smooth surface to ensure the durability of round tube 1 2 , round tube 2 3 , curved plate 9 and filling rod 6 and avoid scratching the film when the surface of round tube 1 2 , round tube 2 3 and filling rod 6 contacts the film.

[0025] In a further preferred embodiment of the present invention, Figure 4 、 Figure 5 and Figure 7As shown, the filling rod 6 includes a filling portion 61, a rod body 62, and a ball 63. One side of the filling portion 61 is fixed to one end of the rod body 62, and the other side of the filling portion 61 is an arc surface. After the filling portion 61 completes filling the opening corresponding to the adsorption hole 21, it forms a flat arc surface with the outer wall of the circular tube 2. The ball 63 is rotatably mounted on the other end of the rod body 62. In this embodiment, please refer to Figure 4 、 Figure 5 and Figure 7 As shown, when the filling rod 6 moves to the bottom end of the curved plate 9, the ball 63 will come into contact with the inclined surface of the curved plate 9. Then, as the ball 63 rotates, the ball 63 is gradually pressed into the adsorption hole 21 along the inclined surface of the curved plate 9 until the ball 63 completely enters the adsorption hole. The rotation of the ball 63 can greatly reduce the friction between the filling rod 6 and the curved plate 9, thereby greatly reducing the wear of the curved plate 9 and the filling rod 6, and extending the service life of the device. The filling portion 61 is arranged in an arc shape, which can directly release the adsorption force between the adsorption hole 21 and the film when the filling portion 61 completes the filling of the adsorption hole opening, and at the same time, the bottom end of the circular tube 2 forms a complete arc surface to roll the film and FPC to prevent the adsorption hole 21 from affecting the de-bubbling effect when the film and FPC are bonded.

[0026] In a further preferred embodiment of the present invention, Figure 4 、 Figure 5 and Figure 7 As shown, a rectangular cavity 64 is formed on the inner wall of the adsorption hole 1 21, and a plurality of rectangular strips 65 are fixedly mounted on the outer peripheral wall of the filling portion 61, and each rectangular strip 65 is slidably connected to the inner wall of the corresponding rectangular cavity 64; In this embodiment, please refer to Figure 5 and Figure 7 As shown, during the reciprocating sliding process of the filling rod 6 in the adsorption hole 21, the rectangular strip 65 is synchronously made to slide in contact with the inner wall of the rectangular cavity 64 (several rectangular strips 65 slide in contact with the inner wall of the four corners of the rectangular cavity 64). Due to the mutual contact between the rectangular strips 65 and the inner wall of the rectangular cavity 64, the filling rod 6 will not produce an angular deviation in the adsorption hole, thereby causing the arc surface of the filling portion 61 to be misaligned with the arc surface of the circular tube 2. At the same time, through the mutual contact between the rectangular strip 65 and the inner wall of the rectangular cavity 64, the reciprocating distance of the filling rod 6 in the adsorption hole 21 is constrained without affecting the gas exchange between the adsorption hole 21 and the circular tube 2, so that the filling rod 6 will not slide out of the adsorption hole 21, and after the filling portion 61 completes filling the opening of the adsorption hole 21, the arc surface of the filling portion 61 is exactly coplanar with the arc surface of the circular tube 2.

[0027] In a further preferred embodiment of the present invention, Figure 1 、 Figure 4 and Figure 5 As shown, the storage mechanism 7 includes a storage box 71, which is fixedly installed in the housing 1 by bolts. A discharge port 72 is opened at the bottom side of the storage box 71 corresponding to the position of the circular tube 2, and the outer wall of the circular tube 2 contacts the inner wall of the bottom opening of the discharge port 72; In this embodiment, please refer to Figure 4 and Figure 5 As shown, when the adsorption hole 21 moves to the top end of the circular tube 2, the filling rod 6 is just moved away from the outer arc wall of the curved plate 9, and the conflict between the filling rod 6 and the curved plate 9 is automatically released. At this time, due to the pressure difference at both ends of the adsorption hole 21, the gas in the adsorption hole 21 pushes the filling rod 6 to move back to the circular tube 2 to release the blocking state of the opening of the adsorption hole 21. At the same time, the adhesive film at the bottom end of the storage box 71 fits the outer wall of the top end of the circular tube 2, thereby blocking the opening of the adsorption hole 21. At this time, the negative pressure cavity in the adsorption hole 21 adsorbs and fixes the head end of the adhesive film on the outer wall of the circular tube 2, so that the adhesive film is gradually drawn out of the storage box 71 through the storage port through the rotation of the circular tube 2 (the height of the discharge port 72 is the same as the thickness of the adhesive film), and the remaining adhesive film remains in the storage box 71 due to the mutual conflict between the adhesive film and the inner wall of the storage box 71, and the adhesive film raw material taking operation can be automatically completed.

[0028] In a further preferred embodiment of the present invention, Figure 1 、 Figure 3 and Figure 8 As shown, the feeding mechanism 8 includes a mounting plate 81, which is provided on the bottom plate of the housing 1, and its top side is in clearance with the outer wall of the circular tube 1 2 and the outer wall of the circular tube 2 3. An electrically controlled telescopic rod 82 is fixedly mounted on the bottom plate of the housing 1, and the driving end of the electrically controlled telescopic rod 82 is fixedly connected to the middle portion of the mounting plate 81 on the side away from the circular tube 2 3. In this embodiment, please refer to Figure 1 and Figure 8 As shown, when loading the FPC, the operator manually inserts the FPC into the mounting groove on the top side of the mounting plate 81 (the top side of the mounting plate 81 is provided with a mounting groove for accommodating the FPC, and the height of the mounting groove is equal to the thickness of the FPC). At this time, due to the mutual interference between the side walls of the FPC and the inner wall of the mounting groove, the FPC is stably placed in the corresponding position on the mounting plate 81, and the FPC loading and installation operation is completed; When the adhesive film is applied to the FPC, the host computer controls the electric telescopic rod 82 to extend (the electric telescopic rod 82 can use a Parker ET series high-precision servo electric cylinder or a HIWIN linear motor module, etc.). As the electric telescopic rod 82 is extended, the mounting plate 81 gradually passes through the gap between the bottom ends of the round tube 1 2 and the round tube 2 3 and the bottom plate of the shell 1, and the adhesive application operation is performed on the top side of the FPC. After the adhesive film is applied to the top side of the FPC, the host computer controls the electric telescopic rod 82 to retract, thereby gradually pulling the mounting plate 81 out of the gap between the bottom ends of the round tube 1 2 and the round tube 2 3 and the bottom plate of the shell 1, and resetting the FPC. At this time, there is sufficient distance between the mounting plate 81 and the round tube 2 3, and they are in an unobstructed state. The operator can directly remove the FPC from the mounting slot.

[0029] In a further preferred embodiment of the present invention, Figure 1 、 Figure 8 、 Figure 9 and Figure 10 As shown, a cavity 83 is provided at the bottom of the mounting plate 81, and an air extraction member 84 and a second pressure-limiting valve 85 are provided on the outer peripheral side of the electric-controlled telescopic rod 82. The end of the second pressure-limiting valve 85 close to the mounting plate 81 is fixedly inserted into the cavity 83, and the air extraction member 84 is fixedly connected to the bottom plate of the housing 1. The interface of the air extraction member 84 close to the mounting plate 81 is connected to the interior of the cavity 83 through a telescopic pipe. Four mesh plates 86 are fixedly installed on the inner top wall of the cavity 83, and the top sides of the four mesh plates 86 extend to the four corners of the mounting groove of the mounting plate 81 and are coplanar with the inner bottom wall of the mounting groove of the mounting plate 81. In this embodiment, please refer to Figure 8 and Figure 10 As shown, after the FPC is placed in the mounting groove of the mounting plate 81, as the electrically controlled telescopic rod 82 is activated, the air extraction member 84 is also synchronously activated to continuously extract gas from the cavity 83 through the telescopic pipe. (The air extraction member 84 is mainly composed of a housing 1 and two pump bodies, and is used to extract gas from the cavity 83 or inject gas into the cavity 83; the telescopic pipe is mainly composed of an outer tube and an inner sliding tube, or a spirally arranged rubber pipe, etc.) As the gas in the cavity 83 is lost and the FPC blocks the hole in the mesh plate 86, a negative pressure chamber is formed in the cavity 83, thereby applying an adsorption force to the FPC at the blind spot position of the FPC, so that the FPC is stably placed in the mounting groove. The FPC is adsorbed through the 86 holes in the stencil, which can provide a certain support force for the FPC to prevent the FPC from being damaged due to excessive force at the adsorption position. As the negative pressure in the cavity 83 decreases, the pressure difference at both ends of the pressure limiting valve also increases. After the pressure difference at both ends of the pressure limiting valve reaches the threshold, the external gas passes through the pressure limiting valve and flows into the cavity 83 to replenish the gas lost in the cavity 83, thereby avoiding excessive negative pressure in the cavity 83, which causes excessive force on the FPC and thus damages the FPC.

[0030] In a further preferred embodiment of the present invention, Figure 2 and Figure 11 As shown, one end of the circular tube 2 away from the air extraction mechanism 5 extends to the outside of the housing 1; The driving mechanism 4 includes a motor 1 41, which is fixedly mounted on the housing 1 at a position corresponding to the circular tube 1 2 via a bracket. A gear ring 42 is fixedly sleeved on the circular tube 2 at a position corresponding to the driving end of the motor 1 41, and the gear ring 42 is meshed with the driving end of the motor 1 41 via a gear. A motor 2 43 is fixedly mounted on the housing 1 at a position corresponding to the circular tube 2 3, and the driving end of the motor 2 43 is inserted into the shell wall of the housing 1 and fixedly connected at the axial center position of the circular tube 2 3. In this embodiment, please refer to Figure 2 and Figure 11 When the device is in use, the host is controlled to control motor 1 41 or motor 2 43 to rotate forward or reverse, thereby driving tube 1 2 to flip forward or tube 2 3 to rotate forward and reverse through the gear ring 42 (a gear is fixedly installed on the driving end of motor 1 41, and the gear is engaged with the gear ring 42). (Motor 1 41 and motor 2 43 can use self-locking stepper motors or brake motors, etc.).

[0031] In a further preferred embodiment of the present invention, Figure 1 and Figure 11 As shown, the air extraction mechanism 5 includes two air pumps 51, which are fixedly mounted on the other side of the housing 1, and the air inlet ends thereof are connected to the interior of the circular tube 1 2 and the interior of the circular tube 2 3 respectively through connecting pipes. An air pressure monitoring sensor 52 is fixedly mounted on the other side of the housing 1, and the air pressure monitoring sensor 52 is located above the corresponding air pump 51, and the monitoring end of the air pressure monitoring sensor 52 is inserted into the circular tube 1 2; In this embodiment, please refer to Figure 1 and Figure 11 As shown, when extracting the gas in the circular tube 1 2 and the circular tube 2 3, the control host controls the air pump 51 to start, and continuously extracts the gas in the circular tube 1 2 and the circular tube 2 3 through the connecting pipe. When the air pressure monitoring sensor 52 detects that the negative pressure intensity in the circular tube 1 2 increases rapidly (the pressure monitoring sensor is electrically connected to the interface of the signal connection line of the control host through the connecting line), the control host controls the air pump 51 at the position of the circular tube 1 2 to stop running, thereby stopping the extraction of the gas in the circular tube 2. The device has a high degree of automation.

[0032] Working Principle: When using this improved FPC full-sheet gluing device, the operator inserts the stacked adhesive film materials into the material storage box 71 to complete the adhesive film material loading operation. Then, the FPC is placed in the mounting groove of the mounting plate 81. Due to the mutual interference between the FPC side wall and the inner wall of the mounting groove, the FPC is stably placed in the corresponding position on the mounting plate 81, and the FPC loading and installation operation is completed. The control device of the control host is activated. First, the air pump 51 is started, and the gas lost in the circular tube 2 and the circular tube 3 is continuously extracted through the connecting pipe. As the gas in the circular tube 2 is lost, the outside gas flows into the circular tube 2 through the adsorption hole 21 to replenish the gas lost in the circular tube 2. Since the amount of gas passing through the adsorption hole 21 is limited, a negative pressure cavity of corresponding strength is formed in the circular tube 2. As the gas in the circular tube 3 is lost, due to the obstruction of the pressure limiting valve 10, a negative pressure cavity of corresponding strength is formed in the circular tube 3. When a sufficient pressure difference is generated at both ends of the pressure limiting valve 10, the outside gas flows into the circular tube 3 through the adsorption hole 2 31 and the pressure limiting valve to replenish the gas lost in the circular tube 3. At the same time, motor 1 41 and motor 2 43 are started, driving round tube 1 2 and round tube 2 3 to rotate in opposite directions. As round tube 1 rotates, when adsorption hole 1 21 moves to the position of storage mechanism 7, due to the adsorption of adsorption hole 1 21 on the head end of the film raw material, the film raw material at the bottom layer in storage box 71 can be slowly drawn out through discharge port 72. Moreover, due to the adsorption of adsorption hole 1 21 on the film raw material, the film raw material adheres to the outer wall of cylinder 1 and rotates with round tube 1 2, thereby completing the film raw material removal operation. The end of the adhesive film is inserted between the circular tube 1 2 and the circular tube 2 3. At this time, the bottom film of the adhesive film is adsorbed on the outer wall of the circular tube 2 3 through the adsorption hole 2. As the circular tube 1 2 and the circular tube 2 3 rotate, the bottom film is torn off from the adhesive film, thereby dividing the adhesive film into two parts: the film body and the bottom film. Subsequently, the head end to the tail end of the film body are gradually moved to the bottom end of the circular tube 1 2 by the rotation of the circular tube 1 2. When the film body moves to the bottom end, due to the mutual interference between the filling rod 6 and the arc plate 9, the filling rod 6 can be pushed toward the opening direction of the adsorption hole 1 21 until the filling rod 6 completes the filling of the adsorption hole opening, so as to remove the adsorption force between the bottom end of the bottom circular tube 1 2 and the film body, and at the same time form a complete arc surface at the bottom end of the circular tube 1 2. During the process of taking the film raw material from the circular tube 2 and conveying the end of the film to the bottom side of the circular tube 2, the control host controls the electric telescopic rod 82 to stretch and push the mounting plate 81 toward the circular tube 2 3, so that the head end to the tail end of the film gradually covers the head end to the tail end of the FPC. At the same time, the complete arc surface of the bottom side of the circular tube 2 gradually completes the rolling of the film from the head end to the tail end of the film, so that the film is firmly bonded to the FPC, and the bubble removal operation of the scraper is simulated to ensure that there are no bubbles between the film and the FPC, and finally the gluing operation of the entire FPC film is completed; It should be noted that, when the head end of the adhesive film moves to the bottom end position of the circular tube 1 2, the adhesive film cooperates with the arc plate 9 to complete the blocking of all the adsorption holes 1 21 on the circular tube 1 2. At this time, the air pressure inside the circular tube 1 2 drops rapidly. At this time, the air pump 51 at the circular tube position stops running, thereby stopping the gas extraction in the circular tube 1 2, preventing the circular tube 1 2 from immediately drawing out the second layer of adhesive film from the storage mechanism 7 after drawing out the first layer of adhesive film from the storage mechanism 7, which affects the subsequent use of the device. Moreover, due to the clamping and pulling of the adhesive film by the circular tube 1 2 and the circular tube 2 3, and the rolling of the film body by the circular tube, even if the subsequent part of the adhesive film loses the adsorption constraint of the adsorption hole 1 21 on the film body, it will not affect the subsequent adhesive laminating operation. After the FPC completes the whole-plate gluing operation, the control host stops the operation of motor 1 41 and motor 2 43. At this time, the operator can directly tear off the bottom film from the round tube 2 3, and then continue to operate the control device of the control host. The electric telescopic rod 82 shrinks, thereby gradually pulling the mounting plate 81 out of the gap between the bottom ends of the round tubes 1 2 and 2 3 and the bottom plate of the shell 1, and resetting the FPC. When the tail end of the FPC moves to the gap between the bottom end of the round tube 2 3 and the bottom plate of the shell 1, due to the adsorption The second hole 31 adsorbs the tail end of the film body, and the waste material at the tail end of the film body is adsorbed and fixed on the outer wall of the second circular tube 3. At this time, the air pump 51 at the position of the second circular tube 3 stops running. Due to the obstruction of the pressure limiting valve, the tail end of the waste material of the film body is still firmly adsorbed on the outer wall of the second circular tube 3 by the second adsorption hole 31, so that the waste material of the film body is gradually torn off from the FPC by the rotating second circular tube 3. After the FPC is reset, the waste material is directly torn off from the outer wall of the second circular tube 3, and finally the whole-plate gluing operation on the FPC is completed; It should be noted that when the air pump 51 at the position of the second circular tube 3 stops running, the openings of the second adsorption holes 31 that are not covered by the film waste will no longer generate adsorption force on the film when they are attached to the film, so as to prevent the second circular tube 3 from tearing off the metal dome or adhesive from the FPC when tearing off the film waste. After the FPC is reset, there is enough space between the mounting plate 81 and the round tube 2 3. At this time, the FPC is in an unobstructed state, and the operator can directly take out the FPC from the mounting slot. The above-mentioned repeated operation can be used to continuously glue the entire FPC.
