Description

Technical Field

[0001] This invention belongs to the technical field of adhesive application and installation equipment, and particularly relates to a touch screen adhesive application and installation machine for oven control panels. Background Technology

[0002] The oven's control panel includes a button panel and a touchscreen panel. During assembly, the worker first fixes the control panel base to a positioning fixture. Then, a sliding table on a glue applicator moves the glue applicator head onto the base. A pump delivers glue from the applicator head, leaving a strip of glue on the base. The worker then removes the fixture and manually presses the touchscreen onto the base, using the glue to bond them together. However, existing equipment and methods rely heavily on worker skill, consuming significant manpower. Prolonged repetitive work can lead to decreased worker focus, resulting in uneven pressing pressure, inconsistent adhesion strength between the touchscreen and the base, and misaligned touchscreens. This leads to a high defect rate for oven touchscreen control panels. Therefore, designing a touchscreen glue application and installation machine for oven control panels that saves manpower and improves adhesion accuracy and uniformity has become an urgent technical problem. Summary of the Invention

[0003] To solve the above problems, the present invention provides a touch screen adhesive application and installation machine for oven control panels.

[0004] The technical solution of this invention is a touch screen adhesive application and installation machine for an oven control panel, comprising a processing table and a PLC controller, wherein the processing table is equipped with... The installation mechanism includes a second conveyor chain, a glue applicator and a presser. The top of the second conveyor chain is provided with glue applicator and bonding station arranged along the conveying direction. The second conveyor chain is also equipped with a positioning fixture for placing the operation panel base and the touch screen. The position of the glue applicator corresponds to the glue applicator and the position of the presser corresponds to the bonding station. The first feeding mechanism is equipped with a conveyor chain for conveying the base of the operation panel to the installation mechanism; The first transfer mechanism is equipped with an electric suction cup for picking up the base of the operation panel and a slide table for reciprocating the electric suction cup between the conveyor chain and the glue application station. The second feeding mechanism is equipped with a conveyor chain three for conveying the touch screen to the installation mechanism; The second transfer mechanism is equipped with an electric suction cup 2 for picking up the touch screen, and a slide table 2 for reciprocatingly transporting the electric suction cup 2 between the conveyor chain 3 and the bonding station. The unloading mechanism is equipped with forks for supporting the control panel base, unloading plate chain for conveying the control panel base away from the mounting mechanism, and unloading cylinder for driving the forks to reciprocate between the bonding station and the unloading plate chain. The glue applicator includes a base connected to a processing table, a cross slide connected to the base, a glue applicator head connected to the cross slide, and a glue pipe and a storage tank connected in sequence to the glue applicator head. The storage tank is equipped with a liquid pump connected to the glue pipe. The press includes a base two mounted on a processing table, a lifting cylinder two connected to the base two, a vertical telescopic rod three at the bottom of the lifting cylinder two, a lifting frame connected to the bottom of the telescopic rod three, a drive motor, a support frame one, and a slide rail two connected to the bottom of the lifting frame one, a pair of roller shafts one shaft connected to the support frame one, conveyor rollers connected to the roller shafts one, and a drive motor connected to the roller shafts one for synchronous drive. A pressing station is provided between the conveyor rollers, the position and size of which are the same as those of the bonding station. Matching the positioning film, the two ends of the positioning film are wound around different conveying rollers. The slide rail is perpendicular to the roller shaft. The slide rail is slidably connected to the sliding seat. One end of the slide rail is connected to the screw motor. The screw motor is equipped with a drive screw that is threadedly connected to the sliding seat. The bottom surface of the sliding seat is connected to the support frame. The support frame is connected to the roller shaft, which is parallel to the roller shaft. The roller shaft is connected to the pressing roller. The pressing roller is positioned above the pressing station. The top surface of the positioning fixture is provided with a first receiving groove for placing a touch screen and a second receiving groove for placing an operation panel base. The second receiving groove is located below the first receiving groove, and a first limiting plane for supporting the touch screen is formed between the first receiving groove and the second receiving groove. The PLC controller is electrically connected to the mounting mechanism, feeding mechanism 1, transfer mechanism 1, feeding mechanism 2, transfer mechanism 2, and unloading mechanism.

[0005] After adopting the above method, the operation panel base to be processed and the touch screen are respectively placed into the feeding mechanism one and the feeding mechanism two. The positioning fixture is installed on the conveyor chain two by means of bonding, snap-fit ​​connection, etc., and is initially in the glue application station position. The worker operates the PLC controller to send an electrical signal to start the feeding mechanism one, the transfer mechanism one, the feeding mechanism two, the transfer mechanism two, the installation mechanism and the unloading mechanism. The processing steps include: Step one, the operation panel base is first conveyed to the installation mechanism by the conveyor chain one. When the operation panel base is sent to the end of the conveyor chain one, the electric suction cup one of the transfer mechanism one picks up the operation panel base. The slide table one conveys the electric suction cup one and the operation panel base to move above the glue application station. Then, the electric suction cup one releases the operation panel base, and the operation panel base falls through the first receiving groove and enters the second receiving groove, completing the feeding of the operation panel base. Step 2: The glue applicator applies glue to the top surface of the control panel base. The cross slide on the base drives the glue applicator head to move horizontally, aligning it with different positions on the top surface of the control panel base. After aligning with a position, the infusion pump draws glue from the storage tank and delivers the glue through the glue pipe to the glue applicator head. The glue flows out from the glue applicator head onto the control panel base to form a glue strip, thus completing the glue application to the control panel base. Step 3: The second conveyor chain transports the positioning fixture to the bonding station. The second conveyor chain transports the touch screen to the installation mechanism. When the touch screen is delivered to the end of the second conveyor chain, the electric suction cup 2 of the transfer mechanism 2 picks up the touch screen. The second slide table transports the electric suction cup 2 and the touch screen to the top of the bonding station. The electric suction cup 2 releases the touch screen, and the touch screen falls into the first receiving groove and presses on the first limiting plane, completing the loading of the touch screen. Step four: The presser presses the touchscreen and the operation panel base together, allowing the adhesive applied to the top surface of the operation panel base to bond them together. The lifting cylinder two on base two drives the telescopic rod three downwards, which in turn lowers the lifting frame. The support frame one connected to the lifting frame descends along with the slide rail two. The support frame one, driven by roller shaft one and conveyor rollers, lowers the positioning film located in the pressing station, covering the positioning fixture. As the lifting frame descends further, the slide rail two, driven by the support frame two and roller shaft one, lowers the positioning film. Shaft 2 drives the pressing roller to press against the positioning fixture through the positioning film; then, lifting cylinder 2 stops driving telescopic rod 3, and screw motor 2 drives screw 2 to rotate, which in turn drives threaded sliding seat 2 to move along slide rail 2, thereby moving the pressing roller. During this process, the soft rubber positioning film increases the friction between the pressing roller and the positioning fixture, causing the pressing roller to roll while moving horizontally, and repeatedly press against the positioning fixture, improving the uniformity of the adhesion between the touch screen and the operation panel base; The positioning film also avoids the pressure roller directly squeezing the touch screen. Utilizing the flexibility and elasticity of the positioning film, it protects the surface of the touch screen from damage caused by the pressure roller when it presses against it. It also prevents the other side of the touch screen from tilting upwards and protruding from the first receiving groove when the pressure roller presses on one side, keeping the relative position of the touch screen and the operation panel base unchanged during bonding, thus improving bonding accuracy. Finally, the lifting cylinder two drives the retraction rod three to retract upwards, driving the lifting frame, positioning film, and pressure roller back to their original positions, completing the compression bonding of the touch screen and the operation panel base. By synchronously starting the drive motor, the drive motor drives the roller shaft one to rotate synchronously. The roller shaft one drives the conveyor roller to rotate in the same direction, releasing the positioning film wound on one conveyor roller. The other conveyor roller rewinds the part of the positioning film that was pressed by the pressure roller. Because the positioning film in the pressing station is deformed by the reciprocating pressure of the pressure roller, the rotation of the conveyor roller in the same direction replaces the positioning film in the pressing station, ensuring that the positioning film can perfectly cover the positioning fixture during the next pressing. Step 5: The unloading cylinder drives the forks to move to the bonding station and lifts the control panel base from below. At this time, the touch screen has been bonded to the top surface of the control panel base. The unloading cylinder then drives the forks to move, moving the control panel base to the unloading chain. The unloading chain then transports the bonded control panel base and the touch screen, completing the unloading process. It realizes the automatic feeding, gluing, pressing and unloading of the operation panel base and the touch screen, saving labor costs. By using positioning fixtures, positioning films and pressing rollers, it improves the bonding accuracy and uniformity between the touch screen and the operation panel base, avoids wear on the touch screen during the bonding process, and reduces the defect rate of the processed oven touch screen operation panels.

[0006] As a further improvement of the present invention, the feeding mechanism includes a mounting frame connected to the processing table, a conveyor chain connected to the mounting frame, and a sorting station and a feeding station arranged sequentially along the conveying direction at the top of the conveyor chain. The mounting frame is connected to a positioning plate, a positioning plate, and a positioning cylinder. The positioning plate and the positioning cylinder are respectively arranged on the left and right sides of the sorting station. The side of the positioning cylinder facing the positioning plate is provided with a telescopic rod, which is connected to a push plate. The positioning plate and the push plate are respectively aligned on the left and right sides of the conveyor chain. The positioning plate is connected to a photoelectric sensor facing the push plate. The positioning plate is located at the end of the feeding station and is provided with a photoelectric sensor facing the feeding station.

[0007] As a further improvement of the present invention, the transfer mechanism includes a stand connected to the processing table, a slide table connected to the stand, the slide table including a horizontally arranged slide rail, a sliding seat slidably connected to the slide rail, and a screw motor connected to the end of the slide rail. The two ends of the slide rail are respectively aligned with the loading station and the gluing station. The screw motor is provided with a drive screw that is threadedly connected to the sliding seat. The axis of the drive screw is parallel to the slide rail. A lifting cylinder is connected to the sliding seat. A telescopic rod is provided at the bottom of the lifting cylinder. An electric suction cup is connected to the bottom of the telescopic rod.

[0008] As a further improvement of the present invention, the feeding mechanism 2 includes a mounting frame 2 connected to the processing table, a conveyor chain 3 connected to the mounting frame 2, and a sorting station 2 and a feeding station 2 sequentially arranged on the top of the conveyor chain 3 along the conveying direction. The mounting frame 2 is connected to a positioning plate 3, a positioning plate 4, and a positioning cylinder 2. The positioning plate 3 and the positioning cylinder 2 are respectively arranged on the left and right sides of the sorting station 2. The positioning cylinder 2 is provided with a telescopic rod 6 on the side facing the positioning plate 3. The telescopic rod 6 is connected to a push plate 2. The positioning plate 3 and the push plate 2 are respectively aligned on the left and right sides of the conveyor chain 2. The positioning plate 3 is connected to a photoelectric sensor 3 facing the push plate 2. The positioning plate 4 is arranged at the end of the feeding station 2. The positioning plate 4 is provided with a photoelectric sensor 4 facing the feeding station 2.

[0009] As a further improvement of the present invention, the transfer mechanism 2 includes a stand 2 connected to the processing table, a slide 2 connected to the stand 2, the slide 2 includes a horizontally arranged slide rail 3, a slide seat 3 slidably connected to the slide rail 3, and a screw motor 3 connected to the end of the slide rail 3. The two ends of the slide rail 3 are respectively aligned with the loading station 2 and the bonding station. The screw motor 3 is provided with a drive screw 3 threadedly connected to the slide seat 3. The axis of the drive screw 3 is parallel to the slide rail 3. A lifting cylinder 4 is connected to the slide seat 3. A telescopic rod 5 is provided at the bottom of the lifting cylinder 4. An electric suction cup 2 is connected to the bottom of the telescopic rod 5.

[0010] Using the above method, when the operating panel base is conveyed by the feeding mechanism, it first passes through the sorting station 1 on the conveyor chain 1. The photoelectric sensor 1 on the positioning plate 1 detects whether the operating panel base has entered or exited the sorting station 1. If the photoelectric sensor 1 detects that the operating panel base has entered the sorting station 1, it sends an electrical signal to the PLC controller. The PLC controller pauses the conveyor chain 1 and starts the positioning cylinder 1. The positioning cylinder 1 drives the telescopic rod 1 to extend towards the positioning plate 1. The push plate 1 cooperates with the positioning plate 1 to clamp the operating panel base from both sides, adjusting the position of the operating panel base to align with the positioning plate 1. Then, the positioning cylinder 1 drives the telescopic rod 1 to retract to its original position, the conveyor chain 1 starts again, and the operating panel base is conveyed away from the sorting station and into the feeding station 1. After the operating panel base is attached to the positioning plate 2, it slides relative to the conveyor chain 1 and remains in the feeding station. Inside the first loading station, photoelectric sensor 2 detects the operating panel base inside the loading station and sends an electrical signal to the PLC controller. The PLC controller starts the transfer mechanism 1, and the lifting cylinder 1 drives the telescopic rod 2 to extend downward, bringing the electric suction cup down to adhere to the operating panel base. The electric suction cup 1 opens and holds the operating panel base. Then, the lifting cylinder 1 drives the telescopic rod 2 to lift the electric suction cup 1. Next, the lead screw motor 1 drives the lead screw 1 to rotate, which drives the threaded sliding seat 1 to move along the slide rail 1, so that the electric suction cup 1 moves from the slide rail 1 aligned with one end of the loading station 1 to the end aligned with the glue application station 1. Finally, the lifting cylinder 1 drives the electric suction cup 1 to descend again, placing the operating panel base into the second receiving slot. The electric suction cup 1 releases the operating panel base, and the slide table 1 and the lifting cylinder 1 drive the electric suction cup 1 back above the loading station 1.

[0011] When the touchscreen is conveyed by the feeding mechanism 2, it first passes through the sorting station 2 on the conveyor chain 3. The photoelectric sensor 3 on the positioning plate 3 detects whether the touchscreen has entered or exited the sorting station 2. If the touchscreen has entered the sorting station 2, the photoelectric sensor 3 sends an electrical signal to the PLC controller. The PLC controller pauses the conveyor chain 3 and starts the positioning cylinder 2. The positioning cylinder 2 drives the telescopic rod 6 to extend towards the positioning plate 3. The push plate 2 cooperates with the positioning plate 3 to clamp the touchscreen from both sides, adjusting the touchscreen's position to align with the positioning plate 3. Then, the positioning cylinder 2 drives the telescopic rod 6 to retract to its original position, and the conveyor chain 3 starts again, conveying the touchscreen away from the sorting station 2 and into the feeding station 2. After the touchscreen is attached to the positioning plate 4, it slides relative to the conveyor chain 3, remaining within the feeding station 2. The photoelectric sensor 4 detects the feeding station 2. The touchscreen in position two sends an electrical signal to the PLC controller. The PLC controller activates the transfer mechanism two, and the lifting cylinder four drives the telescopic rod five to extend downwards, causing the electric suction cup two to descend and adhere to the touchscreen. The electric suction cup two opens and holds the touchscreen. Then, the lifting cylinder four drives the telescopic rod five to raise the electric suction cup two. Next, the lead screw motor three drives the lead screw three to rotate, which drives the threaded sliding seat three to move along the slide rail three, so that the electric suction cup two moves from the slide rail three aligned with one end of the loading station two to the end aligned with the bonding station. Finally, the lifting cylinder four drives the electric suction cup two to descend again, placing the touchscreen into the first receiving slot. The touchscreen is pressed on the first limiting plane, and the electric suction cup two releases the touchscreen. The slide table three and the lifting cylinder four drive the electric suction cup two back above the loading station two.

[0012] Positioning plates one to four align the operation panel base and the touch screen to the designated position, and electric suction cups one and two can accurately transport the two and place them into the second and first receiving slots respectively.

[0013] As a further improvement of the present invention, a third receiving groove is provided below the second receiving groove, and a second limiting plane for supporting the operating panel base is formed between the second receiving groove and the third receiving groove. A lifting cylinder three is fixed in the third receiving groove, and a telescopic rod four is provided at the top of the lifting cylinder three. A horizontal support plate one is provided at the top of the telescopic rod four. The unloading mechanism includes a mounting frame three connected to the processing table, an unloading plate chain connected to a mounting frame two, a vertical frame three connected to the mounting frame two, an unloading cylinder connected to the vertical frame three, an unloading cylinder having a telescopic rod seven facing the bonding station, a fork connected to the telescopic rod seven, an unloading station located below the fork at the first end of the unloading plate chain, a lifting cylinder five connected to the unloading station, a telescopic rod eight at the top of the lifting cylinder five, and a horizontal support plate two at the top of the telescopic rod eight.

[0014] After using the above method, the operating panel base is placed into the second receiving groove and pressed onto the second limiting plane. At the beginning of step five, the lifting cylinder three is activated first. The lifting cylinder three drives the telescopic rod four to extend upward, which in turn moves the support plate one upward. The support plate one extends out of the third receiving groove and horizontally lifts the operating panel base until it is higher than the forks. Then, the forks move to the bonding position and are located below the operating panel base. The lifting cylinder three drives the telescopic rod four to lower the support plate one. The operating panel base descends and presses onto the forks, which then support the operating panel base. The control panel base is moved to the unloading station of the unloading plate chain. By activating the lifting cylinder five, the lifting cylinder five drives the telescopic rod eight to extend upward, and the telescopic rod eight drives the support plate two to move upward. The support plate two horizontally lifts the control panel base from the forks. The unloading cylinder drives the forks to move and offset from the unloading station, leaving the control panel base on the support plate two. The lifting cylinder five drives the telescopic rod eight to lower the support plate two. The support plate two lowers to below the unloading plate chain, so that the control panel base presses on the unloading plate chain. The unloading plate chain starts, and the oven touch screen control panel that has been glued leaves the touch screen gluing and installation machine.

[0015] As a further improvement of the present invention, the cross slide table includes an x-axis slide rail connected to a base, an x-axis slide seat slidably connected to the x-axis slide rail, an x-axis motor connected to one end of the x-axis slide rail, an x-axis lead screw threadedly connected to the x-axis slide seat, a z-axis slide rail connected to the x-axis slide seat, a z-axis slide seat slidably connected to the z-axis slide rail, a z-axis motor connected to one end of the z-axis slide rail, a z-axis lead screw threadedly connected to the z-axis slide seat, a y-axis cylinder connected to the z-axis slide seat, a y-axis telescopic rod provided by the y-axis cylinder, a glue applicator connected to the bottom end of the y-axis telescopic rod, and a glue applicator head connected to the glue applicator and having a nozzle with an opening facing downwards.

[0016] Using the above method, the x-axis motor drives the x-axis lead screw to rotate, which in turn drives the threaded x-axis sliding seat to move along the x-axis slide rail. The z-axis slide rail is connected to the x-axis sliding seat, and the z-axis motor drives the z-axis lead screw to rotate. The z-axis lead screw then drives the threaded z-axis sliding seat to move along the z-axis slide rail, thus moving the y-axis cylinder on the horizontal plane. The y-axis cylinder drives the connected y-axis telescopic rod, glue applicator, and glue applicator head to move horizontally together. After the nozzle with the glue applicator head pointing downwards is aligned with the base of the operating panel, the y-axis cylinder drives the y-axis telescopic rod to extend downwards, and the glue applicator head moves down close to the base of the operating panel before spraying out glue, reducing the positional shift of the glue strip due to swinging in the air.

[0017] As a further improvement of the present invention, a drive motor is connected to one end of any roller shaft for linkage, and each roller shaft is connected to a coaxially arranged transmission wheel, and a transmission belt is connected between the transmission wheels.

[0018] By using the above method, the drive motor drives one of the roller shafts to rotate, and then the transmission wheel and transmission belt work together to make the other roller shaft rotate. This ensures that the roller shafts can rotate synchronously and in the same direction, and avoids deviations in the release or rewinding of the positioning film caused by asynchronous rotation of the roller shafts.

The positioning fixture 413 is installed on the conveyor chain 2 41 by means of bonding, snap-fit ​​connection, etc., and is initially in the position of the glue application station 411. The worker operates the PLC controller to send an electrical signal to start the loading mechanism 1 2, the transfer mechanism 1 3, the loading mechanism 2 6, the transfer mechanism 2 5, the installation mechanism 4 and the unloading mechanism 7. The processing steps include: Step 1, the operation panel base is first conveyed to the installation mechanism 4 by the conveyor chain 1 201. When the operation panel base is sent to the end of the conveyor chain 1 201, the electric suction cup 1 301 of the transfer mechanism 1 3 picks up the operation panel base. The slide table 1 conveys the electric suction cup 1 301 and the operation panel base to move above the glue application station 411. Then, the electric suction cup 1 301 releases the operation panel base, and the operation panel base falls through the first receiving groove 4131 and enters the second receiving groove 4132, completing the loading of the operation panel base. Step 2: The glue applicator 42 applies glue to the top surface of the control panel base. The cross slide 422 on the base 421 drives the glue applicator head 423 to move horizontally and align it with different positions on the top surface of the control panel base. After aligning with a position, the infusion pump 426 draws glue from the storage tank 425 and delivers the glue through the glue pipe 424 to the glue applicator head 423. The glue flows out from the glue applicator head 423 onto the control panel base to form a glue strip, thus completing the glue application to the control panel base. Step 3: The second conveyor chain 41 transports the positioning fixture 413 to the bonding station 412. The second conveyor chain 41 then transports the touch screen to the mounting mechanism 4. When the touch screen is delivered to the end of the second conveyor chain 41, the electric suction cup 501 of the transfer mechanism 5 picks up the touch screen. The second slide table transports the electric suction cup 501 and the touch screen to the top of the bonding station 412. The electric suction cup 501 releases the touch screen, and the touch screen falls into the first receiving groove 4131 and presses on the first limiting plane 4133, completing the loading of the touch screen. Step four: Presser 43 presses the touchscreen and the operation panel base together, causing the adhesive applied to the top surface of the operation panel base to bond the two together. Lifting cylinder 432 on base 431 drives telescopic rod 433 to extend downwards. Telescopic rod 433 lowers lifting frame 434, causing support frame 436 connected to lifting frame 434 and slide rail 437 to descend together. Support frame 436, driven by roller shaft 4361 and conveyor roller 4362, lowers positioning film 4364 located in pressing station 4363, covering positioning fixture 413. As lifting frame 434 descends further, slide rail 437, driven by support frame 437... 4. The roller shaft 4375 drives the pressing roller 4376 to press against the positioning fixture 413 through the positioning film 4364. Then, the lifting cylinder 432 stops driving the telescopic rod 433, and the screw motor 4372 drives the screw rod 4373 to rotate. The screw rod 4373 drives the threaded sliding seat 4371 to move along the slide rail 437, thereby moving the pressing roller 4376. During this process, the soft rubber positioning film 4364 increases the friction between the pressing roller 4376 and the positioning fixture 413, causing the pressing roller 4376 to roll while translating, reciprocating on the positioning fixture 413, thus improving the pressure on the touch screen and operation panel base. The uniformity of the bonding between the touchscreen and the operating panel base is improved. The positioning film 4364 also prevents the pressing roller 4376 from directly squeezing the touchscreen. Utilizing the flexibility and elasticity of the positioning film 4364, it protects the surface of the touchscreen from damage caused by the pressing roller 4376 when it presses against it. It also prevents the other side of the touchscreen from tilting upwards and protruding from the first receiving groove 4131 when the pressing roller 4376 presses against one side, maintaining the relative position of the touchscreen and the operating panel base during bonding and improving bonding accuracy. Finally, the lifting cylinder 432 drives the retraction rod 3 to retract upwards, bringing the lifting frame 434, positioning film 4364, and pressing roller 4376 back to their original positions, completing the bonding process between the touchscreen and the operating panel base. Extrusion bonding; by synchronously starting the drive motor 435, the drive motor 435 drives the roller shaft 4361 to rotate synchronously, and the roller shaft 4361 drives the conveyor roller 4362 to rotate in the same direction, releasing the positioning film 4364 wrapped on one conveyor roller 4362. The other conveyor roller 4362 winds up the part of the positioning film 4364 that has been pressed by the pressing roller 4376. Since the positioning film 4364 in the pressing station 4363 is deformed by the reciprocating extrusion of the pressing roller 4376, the conveyor roller 4362 rotates in the same direction to replace the positioning film 4364 in the pressing station 4363, ensuring that the positioning film 4364 can perfectly cover the positioning fixture 413 during the next pressing. Step 5: The unloading cylinder 703 drives the fork 701 to move to the bonding station 412, lifting the operation panel base from below. At this time, the touch screen is already bonded to the top surface of the operation panel base. The unloading cylinder 703 then drives the fork 701 to move, moving the operation panel base to the unloading plate chain 702. The unloading plate chain 702 transports the bonded operation panel base and the touch screen, completing the unloading after processing. This patented touchscreen adhesive installation machine enables automatic feeding, adhesive application, pressing, and unloading of the operation panel base and the touchscreen, saving labor costs. By utilizing the cooperation of positioning fixture 413, positioning film 4364, and pressing roller 4376, the bonding accuracy and uniformity of the touchscreen and the operation panel base are improved, avoiding wear on the touchscreen during the bonding process and reducing the defect rate of processed oven-made touchscreen operation panels.
