Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of touch screen manufacturing, in particular to a point gluing and laminating device for touch screen lamination. BACKGROUND

[0002] A touch screen is generally assembled by a functional sheet and a cover plate. The assembly process of the functional sheet and the cover plate is edge lamination or full lamination according to product performance requirements. The production process of the touch screen mainly includes the following procedures: substrate (functional sheet and cover plate) feeding, cover plate precision point gluing, lamination assembly, and finished product (touch screen) discharging. At present, in the lamination assembly process, the feeding and discharging procedures are interlocked, that is, the substrate feeding of a new batch needs to be completed after the finished product discharging of the current batch, so that the utilization rate of the touch screen production equipment is low. SUMMARY

[0003] The purpose of the present application is to design a point gluing and laminating device for touch screen lamination to solve the problem of low utilization rate of touch screen production equipment.

[0004] The present application is implemented by the following technical solutions:

[0005] A point gluing and laminating device for touch screen lamination comprises a rack, a material preparation table, a feeding and discharging mechanism, and a laminating device installed on the rack. The top of the material preparation table is provided with a first area for receiving a functional sheet. In the transverse direction, the left and right sides of the material preparation table are each provided with a laminating device. The top of the laminating device is provided with a second area for receiving a functional sheet. The laminating device is used to laminate the received functional sheet into a touch screen in the second area. The feeding and discharging mechanism comprises a first discharging arm, a feeding arm, and a second discharging arm which are sequentially arranged in the transverse direction and can move synchronously and reciprocally in the transverse direction. When the feeding arm is located at the left side of the first area, the first discharging arm is located at the left side of the left second area, and the second discharging arm is located at the left side of the right second area. The feeding arm can reciprocally move between the left and right sides of the first area to push the functional sheet received in the first area to the second area on the side in the moving direction. The first discharging arm can move from the left side to the right side of the left second area to unload the touch screen received in the left second area from left to right. The second discharging arm can move from the right side to the left side of the right second area to unload the touch screen received in the right second area from right to left.

[0006] When the above setting structure is adopted, the laminating device can receive the functional sheet transferred from the material preparation table at the second area and laminates the cover plate on the functional sheet to form a touch screen. In this way, after one laminating device is arranged on each of the two opposite sides in the transverse direction of the material preparation table, the functional sheet can be sequentially transferred to the two laminating devices in batches in one reciprocating stroke through the transversely reciprocating material loading arm. Since the material loading arm, the first material unloading arm and the second material unloading arm can be transversely reciprocated synchronously, and their initial positions are located on the same side of the corresponding first area or second area, in each material loading action, one of the first material unloading arm and the second material unloading arm can complete a material unloading action synchronously, that is, one material loading action and one material unloading action are performed synchronously, and one reciprocating stroke can complete two material loading actions and two material unloading actions. Therefore, the point gluing and laminating equipment for touch screen lamination can not wait for the unloading of the previous batch of finished products before loading a new batch of substrates in the production process, but can load the functional sheet on one side and unload the touch screen on the other side, thereby improving the utilization rate of the touch screen production equipment.

[0007] Further, in order to better achieve the present application, the following setting structure is particularly adopted: one compression roller assembly is arranged on each of the left and right sides of the material preparation table, the compression roller assembly comprises a wheel carrier connected to the rack and a horizontally arranged compression roller connected to the wheel carrier; the left compression roller is located to the right of the left second area, and the right compression roller is located to the left of the right second area; the compression roller is located above the corresponding laminating device and forms a first gap between the top of the corresponding laminating device for the touch screen to pass through, and the height of the first gap is less than the thickness of the touch screen so that the compression roller can roll down the top surface of the touch screen.

[0008] When the above setting structure is adopted, the compression roller assembly is arranged on the side of the second area of the laminating device, so that the touch screen needs to pass under the compression roller during the unloading process. In this way, during the unloading process of the corresponding first material unloading arm or second material unloading arm, the compression roller can simultaneously roll the touch screen to improve the lamination quality of the functional sheet and the cover plate synchronously when the unloading is completed.

[0009] Further, in order to better achieve the present application, the following setting structure is particularly adopted: the compression roller and the wheel carrier are connected through a ratchet mechanism to have one-way rotation capability, wherein during the process of the first material unloading arm unloading the touch screen on the corresponding side, the left compression roller can contact the top surface of the touch screen on the corresponding side and rotate, and during the process of the second material unloading arm unloading the touch screen on the corresponding side, the right compression roller can contact the top surface of the touch screen on the corresponding side and rotate.

[0010] When the above setting structure is adopted, the pressing roller can rotate only when it presses the touch screen in the discharging process. When the corresponding first discharging arm or second discharging arm returns, if the touch screen does not completely separate from the corresponding first discharging arm or second discharging arm and returns together, the pressing roller will stop rotating and press the touch screen, so that the touch screen separates from the corresponding first discharging arm or second discharging arm to complete the discharging, thereby avoiding affecting the subsequent work of the laminating device.

[0011] To better achieve the present application, the laminating device comprises a support and a turnover mechanism connected to the rack and a jig movably connected to the support. The top of the jig is provided with a groove for positioning the functional sheet. The groove depth is less than the thickness of the touch screen. The side of the groove facing the material preparation table is provided with a gap for allowing the touch screen to move laterally out of the groove for unloading. The jig is fixedly connected to the corresponding side of the first discharging arm or the second discharging arm.

[0012] When the above setting structure is adopted, the jig is movably arranged on the support and fixedly connected to the corresponding side of the first discharging arm or the second discharging arm, so that it can move synchronously with the corresponding first discharging arm or second discharging arm. In this way, the jig can provide bottom support for the touch screen during the discharging process, which can improve the rolling quality of the pressing roller on the touch screen and further improve the lamination quality of the functional sheet and the cover plate.

[0013] To better achieve the present application, the wheel frame is provided with a buffer spring for providing a pressing force to the pressing roller.

[0014] To better achieve the present application, the laminating device comprises a support and a turnover mechanism connected to the rack and a jig fixedly connected to the support. The top of the jig is provided with a groove for positioning the functional sheet at the second area. The groove depth is less than the thickness of the touch screen. The side of the groove facing the material preparation table is provided with a gap for allowing the touch screen to move laterally out of the groove for unloading.

[0015] To better achieve the present application, the touch screen laminating point gluing and laminating equipment further comprises a point gluing device. In the lateral direction, one point gluing device is arranged on each side of the material preparation table. The turnover mechanism is connected to the corresponding side of the point gluing device for sucking the glued cover plate output by the corresponding side of the point gluing device and laminating it to the functional sheet received by the corresponding side of the second area to obtain a touch screen.

[0016] To better achieve the present application, the laminating device is arranged below the material preparation table.

[0017] When the above setting structure is adopted, the bonding device and the material preparation table have a height difference, so that the touch screen can be unloaded by relying on the gap formed by the height difference between the bonding device and the material preparation table, thus the bonding device and the material preparation table can be arranged close to each other without considering leaving a transverse unloading gap, and the transverse size of the equipment can be reduced.

[0018] In order to better achieve the present application, the following setting structure is particularly adopted: a hopper is further arranged above the material preparation table, the inside of the hopper is used for stacking a plurality of functional sheets, a discharge port is arranged at the bottom of the hopper and corresponds to the first area, and a second gap for the movement of the feeding arm is formed between the hopper and the material preparation table.

[0019] In order to better achieve the present application, the following setting structure is particularly adopted: the feeding and discharging mechanism further comprises a horizontal moving device, the horizontal moving device is fixedly connected with the feeding arm, the first discharging arm and the second discharging arm, and is used for driving the feeding arm, the first discharging arm and the second discharging arm to move synchronously and reciprocally along the horizontal direction.

[0020] In order to better achieve the present application, the following setting structure is particularly adopted: an output conveyor belt is further arranged directly below the material preparation table, the left side of the output conveyor belt is connected with the right side of the bonding device on the left, and the right side of the output conveyor belt is connected with the left side of the bonding device on the right, so as to receive the unloaded touch screen.

[0021] In order to better achieve the present application, the following setting structure is particularly adopted: the side of the bonding device facing the material preparation table is provided with a discharging chute, and the free end of the discharging chute is connected with the output conveyor belt.

[0022] The present application has the following advantages and beneficial effects:

[0023] In the present application, the laminating device can receive the functional sheet transferred from the material preparation table at the second area and laminate the cover plate on the functional sheet to form a touch screen. In this way, after setting one laminating device on each of the opposite sides in the transverse direction of the material preparation table, the functional sheet can be sequentially transferred to the laminating devices on both sides in batches through the transversely moving feeding arm in one reciprocating stroke, that is, one complete feeding stroke can complete two feeding actions. Since the feeding arm, the first discharging arm and the second discharging arm can move transversely and synchronously, and their initial positions are located on the same side of the corresponding first area or second area, then in each feeding action of the feeding arm, one of the first discharging arm and the second discharging arm can synchronously complete one discharging action of the finished product, that is, one feeding action and one discharging action are performed synchronously, and one reciprocating stroke can complete two feeding actions and two discharging actions. Therefore, the point gluing and laminating equipment for touch screen lamination can not wait for the discharging of the finished product of the previous batch before feeding the substrate of the new batch, but can feed the functional sheet on one side and discharge the touch screen on the other side, thereby improving the utilization rate of the touch screen production equipment.

[0050] In the present application, two sets of fitting devices 30 are arranged on opposite sides of the transverse direction of the preparation table 10 respectively, the preparation table 10 cooperates with the feeding arm 21, and the fitting devices 30 on the two sides each cooperate with a discharging arm, and the feeding arm 21 and the two discharging arms can move synchronously in the transverse direction. By controlling the synchronous transverse movement of the feeding arm 21 and the discharging arm, one side is fed and the other side is discharged, thereby improving the utilization rate of the touch screen production equipment.

[0051] The touch screen fitting point gluing device 100 provided by the present application will be described in detail below in combination with the accompanying drawings and specific embodiments and application scenarios. Figures 1 to 11 , through specific embodiments and application scenarios, the touch screen fitting point gluing device 100 provided by the present application will be described in detail below in combination with the accompanying drawings and specific embodiments and application scenarios.

[0052] The application provides a point gluing and adhering device 100 for touch screen adhesion, which is specially designed as follows:

[0053] As shown in Figure 1 and Figure 2 , the point gluing and adhering device 100 for touch screen adhesion comprises a rack 90, a rack body and a mounting table mounted on the top of the rack body, and a standby table 10, a feeding and discharging mechanism 20 and two adhering devices 30 are fixedly mounted on the top of the mounting table. The rack body is provided with a warehouse body equipped with a door, which surrounds the mounting table and the devices in the rack body.

[0054] As shown in Figure 2 and Figure 3 , the standby table 10 is a substantially flat table plate, which is mounted on the mounting table through a support, and a first area for receiving a functional sheet 200 is arranged on the top of the standby table 10, and the functional sheet 200 can be transferred to the first area by manual or special feeding device. On the top of the standby table 10, some necessary limiting structures can be arranged on or around the first area to limit the functional sheet 200 as needed.

[0055] As shown in Figure 4 and Figure 5 , the adhering device 30 is a device for adhering the functional sheet 200 and the cover plate 300 into a touch screen 400, which is mounted on the mounting table through a support. A second area for receiving the functional sheet 200 transferred from the first area of the standby table 10 is arranged on the top of the adhering device 30, and the adhering device 30 can obtain the cover plate 300 which has been point glued from other places, such as the point gluing device 40, and adhere the cover plate 300 on the functional sheet 200 in the second area to obtain the touch screen 400. On the top of the adhering device 30, some necessary limiting structures can be arranged on or around the second area to limit the functional sheet 200 and / or the cover plate 300 as needed.

[0056] In the transverse direction of the point gluing and adhering device 100 for touch screen adhesion, one adhering device 30 is arranged on the left side and the right side of the transverse direction of the standby table 10 respectively, so that the functional sheet 200 received by the first area of the standby table 10 can be transferred to the second area of the adhering device 30 on the corresponding side. There is enough gap between the standby table 10 and the adhering device 30 to allow the touch screen 400 unloaded from the second area to be smoothly discharged through the gap.

[0057] As shown in Figures 4-10As shown, the feeding and discharging mechanism 20 includes a feeding arm 21, a first discharging arm 22 and a second discharging arm 23 fixedly connected with each other through a connecting rod. In the lateral direction, the first discharging arm 22 and the second discharging arm 23 are respectively located on the left side and the right side of the feeding arm 21. By controlling the connecting rod to reciprocate left and right in the lateral direction, the feeding arm 21, the first discharging arm 22 and the second discharging arm 23 can be driven to reciprocate synchronously in the lateral direction.

[0058] The feeding arm 21 is located on the top of the standby table 10 and can reciprocate between the left side and the right side of the first area. During the lateral movement of the feeding arm 21, the feeding arm 21 can pass through the first area and push the functional sheet 200 received in the first area to the second area of the laminating device 30 on the side in the moving direction, for example, during the lateral movement of the feeding arm 21 from the left side to the right side of the first area, the functional sheet 200 received in the first area can be transferred to the second area of the laminating device 30 on the right side of the standby table. The first discharging arm 22 is located on the top of the laminating device 30 on the left side of the standby table 10. During the lateral movement of the first discharging arm 22, the first discharging arm 22 can pass through the second area and push the touch screen 400 received in the second area to the right side to complete discharging. The second discharging arm 23 is located on the top of the laminating device 30 on the right side of the standby table 10. During the lateral movement of the second discharging arm 23, the second discharging arm 23 can pass through the second area and push the touch screen 400 received in the second area to the left side to complete discharging. When the feeding arm 21 is located on the left side of the first area, the first discharging arm 22 is located on the left side of the left second area, and the second discharging arm 23 is located on the left side of the right second area.

[0059] The feeding arm 21 can feed in both directions in the lateral direction, and the first discharging arm 22 and the second discharging arm 23 can only discharge in one direction in the lateral direction. The first discharging arm 22 can move from the left side to the right side of the left second area to unload the touch screen 400 received in the left second area from left to right. The second discharging arm 23 can move from the right side to the left side of the right second area to unload the touch screen 400 received in the right second area from right to left.

[0060] The feeding and discharging mechanism 20 can be equipped with a lateral movement device 24, which can be a pneumatic cylinder, an electric cylinder or an electric screw rod sliding table, etc. The output end of the lateral movement device 24 is fixedly connected with the connecting rod, so that the feeding arm 21, the first discharging arm 22 and the second discharging arm 23 are fixedly connected with the connecting rod. The lateral movement device 24 is electrically connected with the control cabinet. The feeding arm 21, the first discharging arm 22 and the second discharging arm 23 can be automatically driven to reciprocate synchronously in the lateral direction according to the operation program through the lateral movement device 24.

[0061] In this embodiment, the bonding device 30 can receive the functional sheet 200 transferred from the preparation table 10 at the second area and bond the cover plate 300 on the functional sheet 200 to form the touch screen 400. In this way, after the bonding device 30 is arranged on each of the two opposite sides of the preparation table 10 in the transverse direction, the functional sheet 200 can be sequentially transferred to the bonding device 30 on the two sides by the transversely moving feeding arm 21 in batches in one reciprocating stroke, that is, one complete feeding stroke can complete two feeding actions. Since the feeding arm 21, the first discharging arm 22 and the second discharging arm 23 can be transversely and synchronously reciprocated, and their initial positions are located on the same side of the corresponding first area or second area, in each feeding action, one of the first discharging arm 22 and the second discharging arm 23 can synchronously complete one finished product discharging action, that is, one feeding action and one discharging action are synchronously performed, and one reciprocating stroke can complete two feeding actions and two discharging actions. Therefore, the glue-dropping and bonding device for bonding the touch screen can not wait for the finished product of the previous batch to be discharged before feeding the substrate of the next batch, but can feed the functional sheet on one side and discharge the touch screen 400 on the other side, thereby improving the utilization rate of the touch screen production equipment.

[0062] According to some optional embodiments, as shown in Figures 2-5 , Figure 8 and Figure 9 , the bonding device 30 includes a support 31, a turnover mechanism 33 and a jig 32, the support 31 is fixedly connected to the mounting table of the rack 90, the jig 32 is fixedly connected to the support 31, the top of the jig 32 is provided with a groove 321 for positioning the functional sheet 200 at the position corresponding to the second area, and the groove depth of the groove 321 is less than the thickness of the touch screen 400. The groove 321 is provided with a gap 322 on the side facing the preparation table 10, and the gap 322 allows the touch screen 400 to move out of the groove 321 transversely to unload the finished product.

[0063] The jig 32 is provided with a plurality of bottom negative pressure suction ports 323 at the groove 321 for adsorbing the functional sheet 200 before discharging. The side of the jig 32 can also be provided with a lateral negative pressure suction port 324 for adsorbing the functional sheet 200 to the correct position.

[0064] The turnover mechanism 33 includes a turnover motor 332, a turnover plate 331 and a negative pressure suction cup 333, the turnover motor 332 is fixedly connected to the mounting table of the rack 90, the turnover plate 331 is connected to the output shaft of the turnover motor 332, and the negative pressure suction cup 333 is fixed at a specific point on the turnover plate 331 to uniformly adsorb the cover plate 300. The negative pressure suction cup 333 is connected to the turnover plate 331 by a pneumatic cylinder or an electric cylinder and can advance or retreat relative to the turnover plate 331 to adsorb the cover plate 300 or press the cover plate 300 on the functional sheet 200.

[0065] According to some optional embodiments, as shown in Figures 8-11 The bonding device 30 is arranged below the material preparation table 10 as a whole, so that there is a height difference between the bonding device 30 and the material preparation table 10. In this way, the touch screen 400 can rely on the gap formed by the height difference between the bonding device 30 and the material preparation table 10 to complete the discharging, so that the bonding device 30 and the material preparation table 10 can not need to consider leaving a transverse discharging gap. Compared with the case where only the transverse gap is used as the discharging gap between the bonding device 30 and the material preparation table 10, the bonding device 30 and the material preparation table 10 can be arranged closer to each other, so as to reduce the transverse size of the touch screen bonding dispensing and bonding equipment 100.

[0066] According to some optional embodiments, in order to continuously supply the functional sheets 200 to the first area of the material preparation table 10, as shown in Figure 2 , Figure 4 , Figure 6 , Figures 8-11 The touch screen bonding dispensing and bonding equipment 100 further comprises a vertically arranged hopper 60. The interior of the hopper 60 is used to stack and store multiple functional sheets 200, and the bottom of the hopper 60 is provided with a discharge outlet for discharging. The hopper 60 is fixed on the mounting table or the material preparation table 10 by a support, and is located above the material preparation table 10 as a whole. The discharge outlet provided at the bottom of the hopper 60 corresponds to the first area in the vertical direction and forms a second gap 61 with the top of the material preparation table 10. The second gap 61 is slightly larger than the thickness of a single functional sheet 200 and smaller than twice the thickness of the functional sheet 200, so that the hopper 60 can expose a single functional sheet 200 in the second gap 61 at a time.

[0067] The upper feeding arm 21 is arranged close to the top of the material preparation table 10, and the size of the upper feeding arm 21 in the vertical direction is smaller than the thickness of the functional sheet 200. The upper feeding arm 21 can pass through the second gap 61 and push the functional sheet 200 supported on the top of the material preparation table 10 to move during transverse movement.

[0068] According to some optional embodiments, in order to improve the bonding quality of the touch screen 400, as shown in Figures 2-11 A pressure roller assembly 70 is arranged on each of the left and right sides of the material preparation table 10. The pressure roller assembly 70 comprises a wheel frame 71 and a pressure roller 72 connected to the wheel frame 71. The rotation shaft of the pressure roller 72 is arranged horizontally and longitudinally. The wheel frame 71 can be connected to the mounting table of the rack 90, or can be directly connected to the material preparation table 10 or the bonding device 30.

[0069] The pressure roller 72 on the left side of the material preparation table 10 is located on the right side of the second area of the bonding device 30 on the left side of the material preparation table 10, i.e., on the side used for discharging of the bonding device 30 on the left. The pressure roller 72 on the right side of the material preparation table 10 is located on the left side of the second area of the bonding device 30 on the right side of the material preparation table 10, i.e., on the side used for discharging of the bonding device 30 on the right.

[0070] The pressing roller 72 is located above the corresponding side of the laminating device 30 and forms a first gap 76 between the top of the corresponding side of the laminating device 30, the height of the first gap 76 is smaller than the thickness of the touch screen 400 when the second area is unloaded, but the first gap 76 allows the touch screen 400 to pass through, so that the pressing roller 72 can roll down the top surface of the touch screen 400. When the touch screen 400 passes through the first gap 76, the cover plate 300 constituting the touch screen 400 will contact the pressing roller 72, and the cover plate 300 will be slightly pressed towards the functional sheet 200 to flatten the optical adhesive layer between the cover plate 300 and the functional sheet 200, so that the cover plate 300 can be more uniformly laminated with the functional sheet 200.

[0071] The wheel surface of the pressing roller 72 can be rubber, which allows a certain surface deformation when rolling the touch screen 400.

[0072] In the embodiment, the pressing roller assembly 70 is arranged on the side of the second area of the laminating device 30, so that the touch screen 400 needs to pass under the pressing roller 72 during the unloading process, so that the corresponding first unloading arm 22 or the second unloading arm 23 can simultaneously roll the touch screen 400 during the unloading process, so as to simultaneously improve the lamination quality of the functional sheet 200 and the cover plate 300 when the unloading is completed.

[0073] In some embodiments, as shown in Figure 3 and Figure 11 The pressing roller assembly 70 adopts a one-way rotation form, specifically, the shaft end of the pressing roller 72 is provided with a ratchet wheel 73, and the wheel frame 71 is provided with a pawl 74 matched with the ratchet wheel, so that the pressing roller 72 and the wheel frame 71 are connected through the ratchet mechanism to have one-way rotation capability.

[0074] The one-way rotation direction of the pressing roller 72 is that during the process of the first unloading arm 22 unloading the touch screen 400 on the corresponding side, the left pressing roller 72 can contact the top surface of the touch screen 400 on the corresponding side and rotate; during the process of the second unloading arm 23 unloading the touch screen 400 on the corresponding side, the right pressing roller 72 can contact the top surface of the touch screen 400 on the corresponding side and rotate.

[0075] In the embodiment, the pressing roller 72 can only rotate when pressing the touch screen 400 in the unloading process, and when the touch screen 400 does not completely separate from the corresponding first unloading arm 22 or the second unloading arm 23 and returns together, the pressing roller 72 will stop rotating and press the touch screen 400, so as to make the touch screen 400 separate from the corresponding first unloading arm 22 or the second unloading arm 23 to complete the unloading, thereby avoiding affecting the subsequent work of the laminating device 30.

[0076] In some embodiments, as shown in Figure 5、 Figure 7 and Figure 11 As shown in

[0077] In some embodiments, as shown in Figures 4-11 In the case that the roller assembly 70 adopts the one-way rotation form, the jig 32 of the laminating device 30 is particularly changed to be movably arranged on the support 31, and the jig 32 is fixedly connected with the first blanking arm 22 or the second blanking arm 23 of the corresponding side, so that the jig 32 can move horizontally synchronously with the first blanking arm 22 or the second blanking arm 23 of the corresponding side. In this way, during the blanking process, the jig 32 can always provide bottom support for the touch screen 400, which can improve the rolling quality of the roller 72 on the touch screen 400, and further improve the lamination quality of the functional sheet 200 and the cover plate 300.

[0078] As shown in Figure 7 The first blanking arm 22 and the second blanking arm 23 and the jig 32 of the corresponding side jointly form an air channel, and the connection between them jointly constitutes a lateral negative pressure suction port 324 for attracting the functional sheet 200 to the correct position.

[0079] According to some optional embodiments, as shown in Figure 1 The touch screen laminating dispensing laminating equipment 100 further comprises a dispensing device 40. In the transverse direction, the left and right sides of the preparation table 10 are each provided with a dispensing device 40. The dispensing device 40 comprises a conveying belt 41 arranged longitudinally, and a visual dispensing machine 42 and a tail end tray 43 arranged along the conveying belt. The upstream section of the tail end tray 43 is fixed and connected to the downstream end of the conveying belt 41, and the downstream end of the tail end tray 43 is connected to the corresponding side of the turnover mechanism 33.

[0080] As shown in Figure 3 、 Figure 8 and Figure 9 The flap 331 of the turnover mechanism 33 and the negative pressure suction cup 333 arranged on the flap 331 are located below the tail end tray 43 and are arranged upward. The middle part of the tail end tray 43 is provided with a longitudinal through opening 431, so that the negative pressure suction cup 333 is exposed below the opening 431, and the negative pressure suction cup 333 can suck the bottom surface of the dispensing cover plate 300 output by the corresponding side of the dispensing device 40 from below the tail end tray 43. The flap 331 of the turnover mechanism 33 can be turned over from below to above through the opening 431 and finally turned over to above the top of the laminating device 30, so that the negative pressure suction cup 333 can laminate the sucked cover plate 300 with the bottom surface upward to the functional sheet 200 received by the second area of the corresponding side to obtain the touch screen 400.

[0081] In some embodiments, as shown inFigure 2 and Figure 8 As shown in Figs. 13 and 14, a cover plate material preparation table 81 is arranged between the two conveyors 41, and a vertically arranged cover plate hopper 83 and a cover plate feeding arm 82 are arranged above the cover plate material preparation table 81. The cover plate hopper 83 is internally used for stacking a plurality of cover plates 300, and a third gap is formed between the bottom discharge port of the cover plate hopper 83 and the top of the cover plate material preparation table 81. The third gap is slightly larger than the thickness of the cover plate 300 and smaller than twice the thickness of the cover plate 300, so that the cover plate hopper 83 can expose a single cover plate 300 in the third gap at a time. The cover plate feeding arm 82 is fixedly connected with the transverse moving device 24 of the feeding and discharging mechanism 20, so as to be synchronously transversely reciprocated with the feeding arm 21, the first discharging arm 22 and the second discharging arm 23. When the feeding arm 21 is located at the left side of the first area, the cover plate feeding arm 82 is located at the left side of the cover plate hopper 83. The cover plate feeding arm 82 is arranged close to the top of the cover plate material preparation table 81, and the size of the cover plate feeding arm 82 in the vertical direction is smaller than the thickness of the cover plate 300. The cover plate feeding arm 82 can move along the transverse direction and pass through the third gap to push the cover plate 300 on the top of the cover plate material preparation table 81 to the corresponding side of the conveyor 41 for feeding. It can be seen that the structure for feeding the cover plate 300 is similar to the structure for feeding the functional sheet 200 in structure, and the two can be linked together to complete the feeding of the cover plate 300 at the same time of completing the feeding of the functional sheet 200.

[0082] According to some optional embodiments, as shown in Figs. 15 and 16, the dispensing and bonding device 100 further comprises a longitudinally arranged output conveyor 50 arranged directly below the material preparation table 10. The left side of the output conveyor 50 is connected with the right side of the left bonding device 30, and the right side of the output conveyor 50 is connected with the left side of the right bonding device 30, so as to receive the touch screen 400 unloaded from the two bonding devices 30. Figure 1 、 Figure 8 and Figure 10 As shown in Figs. 15 and 16, the dispensing and bonding device 100 further comprises a longitudinally arranged output conveyor 50 arranged directly below the material preparation table 10. The left side of the output conveyor 50 is connected with the right side of the left bonding device 30, and the right side of the output conveyor 50 is connected with the left side of the right bonding device 30, so as to receive the touch screen 400 unloaded from the two bonding devices 30.

[0083] As shown in Figs. 15 and 16, the dispensing and bonding device 100 further comprises a longitudinally arranged output conveyor 50 arranged directly below the material preparation table 10. The left side of the output conveyor 50 is connected with the right side of the left bonding device 30, and the right side of the output conveyor 50 is connected with the left side of the right bonding device 30, so as to receive the touch screen 400 unloaded from the two bonding devices 30. Figure 7 、 Figure 9 and Figure 11 As shown in Figs. 15 and 16, the dispensing and bonding device 100 further comprises a longitudinally arranged output conveyor 50 arranged directly below the material preparation table 10. The left side of the output conveyor 50 is connected with the right side of the left bonding device 30, and the right side of the output conveyor 50 is connected with the left side of the right bonding device 30, so as to receive the touch screen 400 unloaded from the two bonding devices 30.
