Description

Technical Field

[0001] The present invention relates to the technical field of touch screen manufacturing, and more specifically, to a dispensing and laminating device for touch screen lamination. Background Art

[0002] A touch screen is generally assembled from two parts, a functional sheet and a cover plate. The assembly process of the functional sheet and the cover plate is assembled together by edge lamination or full lamination according to the product performance requirements. The production process of the touch screen mainly includes processes such as feeding of the base materials (functional sheet and cover plate), precise dispensing on the cover plate, laminating and assembling, and discharging of the finished product (touch screen). Currently, in the laminating and assembling process, there is an interlock situation in the feeding and discharging processes, that is, it is necessary to complete the discharging of the finished products of the current batch before feeding the base materials of the new batch, resulting in a low utilization rate of the touch screen production equipment. Summary of the Invention

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

[0004] The present invention is achieved by the following technical solutions: A dispensing and laminating device for touch screen lamination includes a frame and a stock preparation table, a loading and unloading mechanism, and a laminating device installed on the frame; a first area for receiving functional sheets is provided at the top of the stock preparation table. Horizontally, a laminating device is provided on each of the left and right sides of the stock preparation table. A second area for receiving functional sheets is provided at the top of the laminating device. The laminating device is used to laminate the received functional sheets into a touch screen in the second area; the loading and unloading mechanism includes a first unloading arm, a loading arm, and a second unloading arm that are sequentially arranged from left to right along the horizontal direction and can reciprocate synchronously along the horizontal direction; when the loading arm is located on the left side of the first area, the first unloading arm is located on the left side of the second area on the left, and the second unloading arm is located on the left side of the second area on the right; the loading arm can reciprocate between the left and right sides of the first area to push the functional sheets received in the first area to the second area on the side in the moving direction; the first unloading arm can horizontally move from the left side of the second area on the left to the right side to unload the touch screen received in the second area on the left from left to right; the second unloading arm can horizontally move from the right side of the second area on the right to the left side to unload the touch screen received in the second area on the right from right to left.

[0005] When the above-mentioned setting structure is adopted, the laminating device can receive the functional sheet transferred from the stock table at the second area and laminate the cover plate on the functional sheet in place to form a touch screen. In this way, after arranging a laminating device on each of the opposite sides in the lateral direction of the stock table, the feeding arm that moves horizontally can transfer the functional sheets to the laminating devices on both sides in sequence in several times during a reciprocating stroke, that is, two feeding operations can be completed in a complete feeding stroke. Since the feeding arm, the first discharging arm, and the second discharging arm can reciprocate horizontally synchronously, and their initial positions are all on the same side of the corresponding first area or second area, then, during each feeding operation of the feeding arm, one of the first discharging arm and the second discharging arm can synchronously complete a discharging operation of a finished product, that is, a feeding operation and a discharging operation are carried out synchronously, and two feeding operations and two discharging operations can be completed in a reciprocating stroke. Therefore, the dispensing and laminating equipment for touch screen lamination can, during the production process, not wait for the previous batch of finished products to be discharged before loading a new batch of substrates, but can load the functional sheets on one side while discharging the touch screen on the other side, which can improve the utilization rate of the touch screen production equipment.

[0006] Furthermore, to better implement the present invention, the following setting structure is specifically adopted: a pressing roller assembly is arranged on each of the left and right sides of the stock table, and the pressing roller assembly includes a wheel frame connected to the frame and a horizontally arranged pressing roller connected to the wheel frame; the pressing roller on the left is located on the right side of the second area on the left, and the pressing roller on the right is located on the left side of the second area on the right; the pressing roller is located above the corresponding laminating device on the corresponding side and forms a first gap for the touch screen to pass through between the top of the corresponding laminating device, and the height of the first gap is less than the thickness of the touch screen so that the pressing roller can roll down on the top surface of the touch screen.

[0007] When the above-mentioned setting structure is adopted, a pressing 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 pressing roller during the discharging process to complete the discharging. In this way, during the discharging process of the corresponding first discharging arm or second discharging arm, the pressing roller can simultaneously roll the touch screen to synchronously improve the laminating quality between the functional sheet and the cover plate when the discharging is completed.

[0008] Furthermore, to better implement the present invention, the following setting structure is specifically adopted: the pressing roller is connected to the wheel frame through a ratchet mechanism to have the ability of one-way rotation. Among them, during the process of the first discharging arm unloading the touch screen on the corresponding side, the pressing roller on the left can contact the top surface of the touch screen on the corresponding side and rotate, and during the process of the second discharging arm unloading the touch screen on the corresponding side, the pressing roller on the right can contact the top surface of the touch screen on the corresponding side and rotate.

[0009] When the above-mentioned setting structure is adopted, the pressing roller can only rotate when pressing down on the touch screen during the blanking process. When the corresponding first blanking arm or the second blanking arm returns, if the touch screen does not completely separate from the corresponding first blanking arm or the second blanking arm and returns along with it, the pressing roller will stop rotating and squeeze the touch screen, prompting the touch screen to separate from the corresponding first blanking arm or the second blanking arm to complete the blanking, avoiding affecting the subsequent work of the laminating device.

[0010] Further, to better implement the present invention, the following setting structure is particularly adopted: The laminating device includes a support and a flipping mechanism connected to the frame, and a jig movably connected to the support. A groove for positioning the functional sheet is provided at the top of the jig. The depth of the groove is less than the thickness of the touch screen. A notch for allowing the touch screen to move laterally out of the groove for unloading is provided on one side of the groove facing the stock table; the jig is fixedly connected to the corresponding first blanking arm or the second blanking arm on the corresponding side.

[0011] When the above-mentioned setting structure is adopted, the jig is movably arranged on the support and fixedly connected to the corresponding first blanking arm or the second blanking arm on the corresponding side, so that it can move horizontally synchronously with the corresponding first blanking arm or the second blanking arm. In this way, during the blanking process, the jig can always provide bottom support for the touch screen, which can improve the rolling quality of the pressing roller on the touch screen, and further improve the laminating quality of the functional sheet and the cover plate.

[0012] Further, to better implement the present invention, the following setting structure is particularly adopted: The wheel frame is provided with a buffer spring for providing a downward pressure to the pressing roller.

[0013] Further, to better implement the present invention, the following setting structure is particularly adopted: The laminating device includes a support and a flipping mechanism connected to the frame, and a jig fixedly connected to the support. A groove for positioning the functional sheet is provided at the top of the jig at the second area. The depth of the groove is less than the thickness of the touch screen. A notch for allowing the touch screen to move laterally out of the groove for unloading is provided on one side of the groove facing the stock table.

[0014] Further, to better implement the present invention, the following setting structure is particularly adopted: The touch screen laminating dispensing equipment further includes a dispensing device. Horizontally, one dispensing device is provided on each of the left and right sides of the stock table. The flipping mechanism is connected to the corresponding dispensing device, and is used to suck the dispensed cover plate output by the corresponding dispensing device and laminate it onto the functional sheet received in the corresponding second area to obtain a touch screen.

[0015] Further, to better implement the present invention, the following setting structure is particularly adopted: The laminating device is integrally arranged below the stock table.

[0016] When the above-mentioned setting structure is adopted, there is a height difference between the laminating device and the stock preparation table, so that the touch screen can complete the blanking depending on the gap formed by the height difference between the laminating device and the stock preparation table. In this way, there is no need to consider leaving a horizontal blanking gap between the laminating device and the stock preparation table, and the laminating device and the stock preparation table can be arranged close to each other to reduce the horizontal size of the equipment.

[0017] Furthermore, to better implement the present invention, the following setting structure is particularly adopted: It further includes a hopper arranged above the stock preparation table. The inside of the hopper is used for stacking multiple functional sheets in layers. The discharge port arranged at the bottom of the hopper corresponds to the first area, and a second gap for the movement of the loading arm is formed between the hopper and the stock preparation table.

[0018] Furthermore, to better implement the present invention, the following setting structure is particularly adopted: The loading and unloading mechanism further includes a transverse movement device. The transverse movement device is fixedly connected to the loading arm, the first blanking arm, and the second blanking arm, and is used to drive the loading arm, the first blanking arm, and the second blanking arm to move synchronously and reciprocally in the horizontal direction.

[0019] Furthermore, to better implement the present invention, the following setting structure is particularly adopted: It further includes an output conveyor belt arranged directly below the stock preparation table. The left side of the output conveyor belt is connected to the right side of the left laminating device, and the right side of the output conveyor belt is connected to the left side of the right laminating device to receive the unloaded touch screen.

[0020] Furthermore, to better implement the present invention, the following setting structure is particularly adopted: A discharge chute is arranged on the side of the laminating device facing the stock preparation table, and the free end of the discharge chute is connected to the output conveyor belt.

[0021] The present invention has the following advantages and beneficial effects: In the present invention, the laminating device can receive the functional sheet transferred from the stock preparation table at the second area and laminate the cover plate on the functional sheet in place to form a touch screen. In this way, after arranging a laminating device on each of the two opposite sides in the lateral direction of the stock preparation table, the feeding arm that moves horizontally can transfer the functional sheets to the laminating devices on both sides in sequence in a reciprocating stroke, that is, two feeding operations can be completed in one complete feeding stroke. Since the feeding arm, the first discharging arm, and the second discharging arm can move horizontally and reciprocally synchronously, and their initial positions are all on the same side of the corresponding first area or second area, then, during each feeding operation of the feeding arm, one of the first discharging arm and the second discharging arm can synchronously complete one discharging operation of the finished product, that is, one feeding operation and one discharging operation are carried out synchronously, and two feeding operations and two discharging operations can be completed in one reciprocating stroke. Therefore, during the production process, the dispensing and laminating equipment for touch screen lamination does not need to wait for the previous batch of finished products to be discharged before feeding the new batch of substrates. Instead, it can feed the functional sheets on one side while discharging the touch screens on the other side, which can improve the utilization rate of the touch screen production equipment.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In the present application, two sets of laminating devices 30 are respectively arranged on opposite sides in the transverse direction of the stock preparation table 10. The stock preparation table 10 cooperates with the loading arm 21, and each of the two laminating devices 30 on both sides cooperates with a unloading arm. The loading arm 21 and the two unloading arms can move synchronously in the transverse direction. By controlling the synchronous transverse movement of the loading arm 21 and the unloading arms, feeding on one side and unloading on the other side are realized, and the utilization rate of the touch screen production equipment is improved.

[0029] The following is combined with the attached Figures 1 to 11 , and through specific embodiments and their application scenarios, the dispensing laminating equipment 100 for touch screen lamination provided by the present application is described in detail.

[0030] The present application provides a dispensing laminating equipment 100 for touch screen lamination, which is specifically configured as follows: Such as Figure 1 and Figure 2As shown, the dispensing and laminating device 100 for touch screen lamination includes a frame 90, a frame body of the frame 90, and a mounting table installed on the top of the frame body. A stock preparation table 10, a loading and unloading mechanism 20, and two laminating devices 30 are fixedly installed on the top of the mounting table. The frame body is equipped with a storage body with a door, and the storage body is arranged around the mounting table to enclose the devices installed on the mounting table and some devices inside the frame body.

[0031] As Figure 2 and Figure 3 shown, the stock preparation table 10 is a substantially flat table board, which is installed on the mounting table through a bracket. A first area for receiving the functional sheet 200 is provided on the top of the stock preparation table 10, and the functional sheet 200 can be transferred to the first area by manual or special loading devices. On the top of the stock preparation table 10, some necessary limiting structures can be set in the first area or around the first area to perform necessary limiting on the functional sheet 200.

[0032] As Figure 4 and Figure 5 shown, the laminating device 30 is a device for laminating the functional sheet 200 and the cover plate 300 into a touch screen 400, and it is installed on the mounting table through a bracket. A second area for receiving the functional sheet 200 transferred from the first area of the stock preparation table 10 is provided on the top of the laminating device 30. The laminating device 30 can obtain the cover plate 300 that has been dispensed from other places, such as from the dispensing device 40, and laminate the cover plate 300 on the functional sheet 200 in the second area to obtain the touch screen 400. On the top of the laminating device 30, some necessary limiting structures can be set in the second area or around the second area to perform necessary limiting on the functional sheet 200 and / or the cover plate 300.

[0033] In the lateral direction of the dispensing and laminating device 100 for touch screen lamination, a laminating device 30 is respectively arranged on the left and right sides in the transverse direction of the stock preparation table 10, so that the functional sheet 200 received in the first area on the stock preparation table 10 can be transferred to the second area of the corresponding laminating device 30 on the left or right side. There is enough clearance between the stock preparation table 10 and the laminating device 30 to allow the touch screen 400 unloaded from the second area to be discharged smoothly through the clearance.

[0034] As Figures 4 to 10 shown, the loading and unloading mechanism 20 includes a loading arm 21, a first unloading arm 22, and a second unloading arm 23 that are fixedly connected to each other through a connecting rod. In the transverse direction, the first unloading arm 22 and the second unloading arm 23 are respectively located on the left and right sides of the loading arm 21. By controlling the connecting rod to reciprocate left and right in the transverse direction, the loading arm 21, the first unloading arm 22, and the second unloading arm 23 can be driven to reciprocate synchronously in the transverse direction.

[0035] The loading arm 21 is located at the top of the stock preparation table 10 and can reciprocate between the left and right sides of the first area. During the lateral movement of the loading arm 21, it 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 loading arm 21 from the left side to the right side of the first area, it can transfer the functional sheet 200 received in the first area to the second area of the laminating device 30 located on the right side of the stock preparation table. The first unloading arm 22 is located at the top of the laminating device 30 on the left side of the stock preparation table 10. During its lateral movement, it can pass through the second area and push the touch screen 400 received in the second area to the right to complete unloading; the second unloading arm 23 is located at the top of the laminating device 30 on the right side of the stock preparation table 10. During its lateral movement, it can pass through the second area and push the touch screen 400 received in the second area to the left to complete unloading. Among them, when the loading arm 21 is located on the left side of the first area, the first unloading arm 22 is located on the left side of the second area on the left, and the second unloading arm 23 is located on the left side of the second area on the right.

[0036] The loading arm 21 can load materials bidirectionally in the lateral direction. The first unloading arm 22 and the second unloading arm 23 can only unload materials unidirectionally in the lateral direction. The first unloading arm 22 can laterally move from the left side of the second area on the left to the right side to unload the touch screen 400 received in the second area on the left in the direction from left to right; the second unloading arm 23 can laterally move from the right side of the second area on the right to the left side to unload the touch screen 400 received in the second area on the right from right to left.

[0037] The loading and unloading mechanism 20 can be equipped with a lateral movement device 24. The lateral movement device 24 can specifically be a cylinder, an electric cylinder, an electric screw slide table, etc. The output end of the lateral movement device 24 is fixedly connected to the connecting rod, so as to be fixedly connected to the loading arm 21, the first unloading arm 22, and the second unloading arm 23. The lateral movement device 24 is electrically connected to the control cabinet. Through the lateral movement device 24, the loading arm 21, the first unloading arm 22, and the second unloading arm 23 can be automatically driven to reciprocate synchronously in the lateral direction according to the running program.

[0038] In this embodiment, the laminating device 30 can receive the functional sheet 200 transferred from the preparation platform 10 at the second area and laminate the cover plate 300 on the functional sheet 200 at the original location to form the touch screen 400. In this way, after a laminating device 30 is set on each of the opposite sides in the lateral direction of the preparation platform 10, the functional sheet 200 can be transferred to the laminating devices 30 on both sides in sequence in one reciprocating stroke by the transversely moving loading arm 21, that is, one complete loading stroke can complete two loading actions. Since the loading arm 21 and the first unloading arm 22 and the second unloading arm 23 can reciprocate synchronously in the lateral direction, and their initial positions are all located on the same side of the corresponding first area or second area, then, during each loading action of the loading arm 21, one of the first unloading arm 22 and the second unloading arm 23 can synchronously complete a finished product unloading action, that is, one loading action and one unloading action are performed synchronously, and one reciprocating stroke can complete two loading actions and two unloading actions. Therefore, during the production process, the touch screen bonding glue dispensing bonding equipment does not need to wait for the previous batch of finished products to be unloaded before loading a new batch of substrates. Instead, the functional sheets can be loaded on one side while the touch screen 400 is unloaded on the other side, which can improve the utilization rate of the touch screen production equipment.

[0039] According to some optional embodiments, Figures 2 to 5 , Figure 8 and Figure 9 As shown, the laminating device 30 includes a support 31, a flip mechanism 33 and a jig 32. The support 31 is fixedly connected to the mounting table of the frame 90, and the jig 32 is fixedly connected to the support 31. A groove 321 for positioning the functional sheet 200 is provided at the top of the jig 32 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 notch 322 on the side facing the material preparation table 10, and the notch 322 allows the touch screen 400 to move laterally out of the groove 321 to unload and complete the unloading.

[0040] The fixture 32 is provided with a plurality of bottom negative pressure suction ports 323 at the groove 321 for adsorbing the functional sheet 200 before feeding. A lateral negative pressure suction port 324 can also be provided on the side of the fixture 32 for adsorbing the functional sheet 200 to place it in the correct position.

[0041] The flip mechanism 33 includes a flip motor 332, a flip plate 331 and a negative pressure suction cup 333. The flip motor 332 is fixedly connected to the mounting platform of the frame 90, the flip plate 331 is connected to the output shaft of the flip motor 332, and the negative pressure suction cup 333 is fixed to a specific point on the flip plate 331 so as to evenly absorb the cover plate 300. The negative pressure suction cup 333 is connected to the flip plate 331 through a cylinder or an electric cylinder, and can move forward or backward relative to the flip plate 331 to absorb the cover plate 300 or press the cover plate 300 onto the functional sheet 200.

[0042] According to some optional embodiments, as Figures 8 to 11 shown, the laminating device 30 is integrally disposed below the stock preparation table 10, such that there is a height difference between the laminating device 30 and the stock preparation table 10. In this way, the touch screen 400 can complete the blanking depending on the gap formed by the height difference between the laminating device 30 and the stock preparation table 10, such that there is no need to consider leaving a horizontal blanking gap between the laminating device 30 and the stock preparation table 10. Compared with the case where only the horizontal distance is used as the blanking gap between the laminating device 30 and the stock preparation table 10, the laminating device 30 and the stock preparation table 10 can be set closer to each other, so as to reduce the horizontal size of the dispensing and laminating device 100 for touch screen lamination.

[0043] According to some optional embodiments, in order to continuously supply the functional sheets 200 to the first area of the stock preparation table 10, as Figure 2 , Figure 4 , Figure 6 , Figures 8 to 11 shown, the dispensing and laminating device 100 for touch screen lamination further includes a vertically disposed hopper 60. The inside of the hopper 60 is used for stacking multiple functional sheets 200 in layers, and a discharge port for discharging materials is provided at the bottom. The hopper 60 is fixed on the installation table or the stock preparation table 10 through a bracket, and is integrally located above the stock preparation table 10. The discharge port provided at the bottom of the hopper 60 corresponds to the first area vertically and forms a second gap 61 with the top of the stock 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, such that the hopper 60 can expose a single functional sheet 200 in the second gap 61 at one time.

[0044] The loading arm 21 is disposed close to the top of the stock preparation table 10, and the dimension of the loading arm 21 in the vertical direction is smaller than the thickness of the functional sheet 200; during the horizontal movement of the loading arm 21, it can pass through the second gap 61 and push the functional sheet 200 supported on the top of the stock preparation table 10 to move.

[0045] According to some optional embodiments, in order to improve the lamination quality of the touch screen 400, as Figures 2 to 11 shown, a pressing roller assembly 70 is provided on each of the left and right sides of the stock preparation table 10. The pressing roller assembly 70 includes a wheel frame 71 and a pressing roller 72 connected to the wheel frame 71. The rotating shaft of the pressing roller 72 is horizontally and longitudinally disposed. The wheel frame 71 can be connected to the installation table of the machine frame 90, or can be directly connected to the stock preparation table 10 or the laminating device 30.

[0046] The pressing roller 72 on the left side of the stock preparation table 10 is located on the right side of the second area of the laminating device 30 on the left side of the stock preparation table 10, that is, on the side for blanking of the left laminating device 30; the pressing roller 72 on the right side of the stock preparation table 10 is located on the left side of the second area on the right side of the stock preparation table 10, that is, on the side for blanking of the right laminating device 30.

[0047] The pressing roller 72 is entirely located above the laminating device 30 on the corresponding side and forms a first gap 76 with the top of the laminating device 30 on the corresponding side. The height dimension of the first gap 76 is smaller than the thickness of the touch screen 400 when it is fed from the second area, but the first gap 76 allows the touch screen 400 to pass through, so that the pressing roller 72 can roll down on the top surface of the touch screen 400. When the touch screen 400 passes through the first gap 76, the cover plate 300 that makes up 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, enabling the cover plate 300 to be more evenly laminated with the functional sheet 200.

[0048] The surface of the pressing roller 72 can be rubber, allowing a certain amount of surface deformation when rolling the touch screen 400.

[0049] In this embodiment, a pressing roller assembly 70 is provided on the side of the second area of the laminating device 30, such that the touch screen 400 needs to pass under the pressing roller 72 during the feeding process to complete the feeding. In this way, during the feeding process of the corresponding first feeding arm 22 or the second feeding arm 23, the pressing roller 72 can simultaneously roll the touch screen 400 to synchronously improve the lamination quality between the functional sheet 200 and the cover plate 300 when the feeding is completed.

[0050] In some embodiments, such as Figure 3 and Figure 11 shown, the pressing roller assembly 70 adopts a one-way rotation form. Specifically, a ratchet wheel 73 is installed at the shaft end of the pressing roller 72, and a ratchet pawl 74 that cooperates with the ratchet wheel is installed on one side of the wheel frame 71, so that the pressing roller 72 and the wheel frame 71 are connected through a ratchet mechanism to have the ability of one-way rotation.

[0051] The one-way rotation direction of the pressing roller 72 is as follows: during the process of the first feeding arm 22 unloading the touch screen 400 on the corresponding side, the pressing roller 72 on the left can contact the top surface of the touch screen 400 on the corresponding side and rotate; during the process of the second feeding arm 23 unloading the touch screen 400 on the corresponding side, the pressing roller 72 on the right can contact the top surface of the touch screen 400 on the corresponding side and rotate.

[0052] In this embodiment, the pressing roller 72 can only rotate when pressing down on the touch screen 400 during the feeding process. When the corresponding first feeding arm 22 or the second feeding arm 23 returns, if the touch screen 400 does not completely disengage from the corresponding first feeding arm 22 or the second feeding arm 23 and returns together, the pressing roller 72 will stop rotating and squeeze the touch screen 400, prompting the touch screen 400 to disengage from the corresponding first feeding arm 22 or the second feeding arm 23 to complete the feeding, avoiding affecting the subsequent work of the laminating device 30.

[0053] In some embodiments, such as Figure 5, Figure 7 and Figure 11 As shown in Figure 7 and Figure 11 , a buffer spring 75 is provided between the wheel carrier 71 and the connected components. The buffer spring 75 can provide a downward pressure to the pressure roller 72, so that the pressure roller 72 can improve the adhesion to the cover plate 300 of the touch screen 400.

[0054] In some embodiments, as Figures 4 to 11 shown, when the pressure roller assembly 70 adopts a one-way rotation form, the fixture 32 of the laminating device 30 is particularly changed to be movably arranged on the support 31. At the same time, the fixture 32 is fixedly connected to the corresponding first blanking arm 22 or the second blanking arm 23, so that the fixture 32 can move horizontally synchronously with the corresponding first blanking arm 22 or the second blanking arm 23. In this way, during the blanking process, the fixture 32 can always provide bottom support for the touch screen 400, which can improve the rolling quality of the pressure roller 72 on the touch screen 400, and further improve the laminating quality of the functional sheet 200 and the cover plate 300.

[0055] As Figure 7 shown, an air channel is formed jointly between the first blanking arm 22 and the second blanking arm 23 and the fixture 32 on the corresponding side. The air channel and their connection points jointly constitute a lateral negative pressure suction port 324 for sucking the functional sheet 200 to make it in the correct position.

[0056] According to some alternative embodiments, as Figure 1 shown, the dispensing device 40 is further included in the dispensing laminating equipment 100 for touch screen laminating. Horizontally, a dispensing device 40 is arranged on each of the left and right sides of the stock table 10. The dispensing device 40 includes a longitudinally arranged conveyor belt 41, a vision dispenser 42 and a tail-end tray 43 arranged along the conveyor belt. The upstream section of the tail-end tray 43 is fixed and connected to the downstream end of the conveyor belt 41, and the downstream end of the tail-end tray 43 is connected to the corresponding side of the flipping mechanism 33.

[0057] As Figure 3 , Figure 8 and Figure 9 shown, the flap 331 of the flipping mechanism 33 and the negative pressure suction cups 333 arranged on the flap 331 are located below the tail-end tray 43 and are arranged upward. A longitudinally penetrating opening 431 is opened in the middle of the tail-end tray 43, so that the negative pressure suction cups 333 are exposed below the opening 431. The negative pressure suction cups 333 can suck the bottom surface of the dispensed cover plate 300 output from the corresponding side of the dispensing device 40 from below the tail-end tray 43. The flap 331 of the flipping mechanism 33 can flip upward through the opening 431 and finally flip to the top of the laminating device 30, so that the negative pressure suction cups 333 can laminate the sucked cover plate 300 with the bottom surface upward onto the functional sheet 200 received in the corresponding second area to obtain the touch screen 400.

[0058] In some embodiments, asFigure 2 and Figure 8 As shown in Figure 8 , a cover stock preparation table 81 is provided between two conveyor belts 41. Above the cover stock preparation table 81, a vertically arranged cover stock hopper 83 and a cover loading arm 82 are provided. The interior of the cover stock hopper 83 is used for stacking and placing multiple cover plates 300. A third gap is formed between the bottom discharge port of the cover stock hopper 83 and the top of the cover stock preparation table 81. The third gap is slightly larger than the thickness of the cover plate 300 and less than twice the thickness of the cover plate 300, so that the cover stock hopper 83 can expose a single cover plate 300 in the third gap at one time. The cover loading arm 82 is fixedly connected to the transverse movement device 24 of the loading and unloading mechanism 20 to be able to reciprocate horizontally synchronously with the loading arm 21, the first unloading arm 22, and the second unloading arm 23. When the loading arm 21 is on the left side of the first area, the cover loading arm 82 is on the left side of the cover stock hopper 83. The cover loading arm 82 is arranged close to the top of the cover stock preparation table 81, and the dimension of the cover loading arm 82 in the vertical direction is less than the thickness of the cover plate 300; the cover loading arm 82 can move horizontally and pass through the third gap to push the cover plate 300 on the top of the cover stock preparation table 81 to be loaded onto the corresponding conveyor belt 41. It can be seen that the structure for loading the cover plate 300 is similar to the structure for loading the functional chip 200 in terms of structure. Linking the two together can complete the loading of the cover plate 300 while completing the loading of the functional chip 200.

[0059] According to some alternative embodiments, as Figure 1 、 Figure 8 and Figure 10 shown, the dispensing and laminating device 100 for touch screen lamination further includes a longitudinally arranged output conveyor belt 50 provided directly below the stock preparation table 10. The left side of the output conveyor belt 50 is connected to the right side of the left laminating device 30, and the right side of the output conveyor belt 50 is connected to the left side of the right laminating device 30 for receiving the touch screens 400 unloaded from the two-sided laminating devices 30.

[0060] In some embodiments, as Figure 7 、 Figure 9 and Figure 11 shown, an inclined discharge chute 34 is provided on the right side of the left laminating device 30 facing the stock preparation table 10, and an inclined discharge chute 34 is provided on the left side of the right laminating device 30 facing the stock preparation table 10. The free end of the discharge chute 34 is connected to the output conveyor belt 50 to better guide the touch screen 400 to move onto the output conveyor belt 50.
