Description

Technical Field

[0001] The present invention relates to the field of automation equipment, and in particular to a mobile phone back cover film tearing, laminating and pressing machine and a laminating and pressing process thereof. Background Art

[0002] Smartphones and tablet computers are commonly used smart terminal devices and an important tool in people's daily production and life.

[0003] In the process of automated assembly of mobile phones, the back cover of the mobile phone is an important part of the mobile phone supporting shell parts. The automatic assembly process of the mobile phone back cover involves the assembly process of multiple sets of auxiliary materials, such as adhesive backing assembly. The adhesive backing needs to be attached to the surface of the mobile phone back cover to assist in fixing and installing other accessories such as mobile phone cameras on the back cover of the mobile phone. The materials involved in the adhesive backing attachment process of the mobile phone back cover include the back cover of the mobile phone and the adhesive backing. The technical problems that need to be solved when realizing the automatic attachment of the adhesive backing include: 1. The problem of automatic feeding and storage of the back cover of the mobile phone; 2. The problem of automatic storage, feeding, and film tearing of the adhesive backing; 3. Since the adhesive backing has a protective film attached to the adhesive layer on the bottom and top surfaces when the adhesive backing is in the incoming state, the protective film of the adhesive backing needs to be torn off before the subsequent adhesive application can be performed. Therefore, the problem of film tearing on the bottom of the adhesive backing needs to be solved before attachment, and the problem of film tearing on the surface of the adhesive backing needs to be solved after attachment; 4. In addition, the adhesive backing is a sheet structure. In order to ensure the efficiency of automation, it is necessary to supply adhesive in batches. Generally, a material box is used as a storage mechanism. Multiple pieces of adhesive are stored in an up-and-down manner for the material picking mechanism to pick up one by one. The material box adopts a fixed installation structure. After the adhesive is taken out, it is necessary to use independent tools to move the adhesive from the stacking station to the material box when reloading the adhesive. The loading efficiency is low, and the adhesive position is prone to offset during the transportation process, affecting the position accuracy of the material when picking up the material; 5. After the adhesive is attached, in order to ensure the flatness of the bonding surface and the completeness of the bonding, the bonding pressure maintenance problem needs to be solved.

[0027] The beneficial effects of the present invention are:

[0028] In view of the defects and shortcomings of the prior art, the present invention independently developed and designed a mobile phone back cover film tearing, bonding and pressing machine which can realize automatic material feeding before bonding of the mobile phone back cover and automatic material unloading and storage after bonding by circulating a plate, a blocking plate and a closing plate, effectively improving the material transfer efficiency, and realizing automatic feeding of the back glue, multi-piece detection, film tearing transfer and automatic bonding. It adopts a detachable material change, effectively improving the back glue feeding and bonding efficiency, and has a bonding and pressure maintaining function, which effectively ensures the bonding quality of the mobile phone back cover film tearing, bonding and pressure maintaining machine and its bonding and pressure maintaining process.

[0029] The present invention aims to provide a device for realizing automatic attachment of adhesive backing of mobile phone back cover and its automatic adhesive bonding, film tearing and pressure holding process, which is applied in the automatic assembly production line of mobile phone auxiliary materials to realize efficient, accurate and high-quality attachment of adhesive backing of mobile phone back cover.

[0030] Firstly, the present invention designs a material tray circulating feeding part as an actuator for circulating supply and automatic material unloading storage of the back cover of the mobile phone. The material tray circulating feeding part uses a feeding bracket arranged in a straight line as a bearing structure. A tray placing station, a material taking station and a tray closing station are arranged at intervals along the straight line direction on the feeding bracket. Two transmission belts for linearly transmitting the material tray and arranged in parallel at intervals are respectively arranged at the three stations (the two transmission belts are tensioned by tensioning wheels, and the tensioning wheels at both ends of the transmission belts are connected by a transmission shaft. The power output by the motor can be transmitted to the transmission shaft through the transmission belt to drive the transmission shaft to drive the tensioning wheel to rotate. When the tensioning wheel rotates, it drives the two transmission belts to rotate synchronously. The three stations are respectively provided with a tray placing mechanism, a material taking and loading mechanism and a tray closing mechanism, wherein the tray placing mechanism and the tray closing mechanism have the same structure, both of which include a horizontal carrier plate arranged in the middle between the two conveyor belts and supporting plates arranged on the front and rear sides of the two conveyor belts. The horizontal carrier plate is driven by a cylinder to move up and down, and the two supporting plates are driven by a cylinder to move horizontally and linearly above the conveyor belts; at the tray placing station, two supporting plates support multiple trays stacked up and down. When a tray needs to be placed, the stacked trays are supported on the horizontal carrier plate, and the supporting plate is pulled outward, and the horizontal carrier plate drives the tray to drop by a tray thickness. After the distance is reached, the two support plates are horizontally inserted above the bottom material tray to separate the bottom material tray and hold the material tray above it again. The horizontal carrier drives the bottom material tray to continue to descend and place it on the transmission belt. The material tray is linearly transmitted to the material picking station via the transmission belt, and is blocked and lifted by the material picking loading mechanism. The material picking loading mechanism may include a blocking block arranged in the two transmission belts and driven up and down by a cylinder, and a horizontal support plate arranged between the two transmission belts. The horizontal support plate is driven to rise and fall by the cylinder so as to carry and lift the blocked cylinder upward to make it fall off the transmission belt in linear motion so as to The robot takes and places the mobile phone back covers in the material tray; when the mobile phone back covers to be bonded in the material tray are taken out and refilled with the mobile phone back covers after bonding, the material loading mechanism puts the material tray back on the conveyor belt, which is transported to the closing station by the conveyor belt. At the closing station, the closing mechanism stacks the material trays filled with the bonded mobile phone back covers from bottom to top on the pallet one by one in the opposite direction of the placing mechanism; thus, the material tray is used as a carrier, and the material tray is used for cyclic placing, blocking and lifting, taking and placing, and closing and unloading. Batch and automatic cyclic feeding and unloading storage of mobile phone back covers are realized, which effectively improves the feeding efficiency of mobile phone back covers and ensures the continuity of feeding.

[0031] Secondly, in order to solve the problems of automatic feeding, transfer and film tearing of adhesive backing, the present invention designs a feeding and film tearing mechanism, which includes a material box mechanism for storing film sheets and lifting and feeding, and a transport mechanism for taking film and transporting transfer film sheets; the material box mechanism of the present invention specifically adopts a material box space formed by a movable material box assembly to store multiple pieces of adhesive backing in an up and down stacked manner, and the movable material box assembly is detachably installed in an installation slide groove formed on the bearing support plate of the bearing assembly by a sliding-in installation manner, and is guided and limited during the sliding process by the groove opened on the inner side wall of the limiting strip of the bearing assembly, thereby effectively ensuring the position accuracy during the sliding-in installation, and through the sliding-in movable installation of the movable material box assembly, after the adhesive backing in the material box space is taken out, the movable material box assembly can be directly removed to replace the material, which effectively improves the adhesive backing replacement efficiency and reduces the replacement cost. The movable material box assembly forms a material box space with an opening at the top through a first side plate, a second side plate and a guide rod vertically arranged on the bottom plate, and uses a load-bearing plate that can move freely in the vertical direction as a glue bearing structure. The jacking mechanism arranged under the load-bearing assembly outputs power to simultaneously drive four ejector rods to pass through the load-bearing support plate of the load-bearing assembly and the bottom plate of the movable material box assembly to extend into the material box space, and is detachably connected to the bottom of the load-bearing plate through an adsorption block. The power output by the ejector rod drives the load-bearing plate to synchronously move upwards with the thickness of a piece of glue as the movement distance unit during the material taking process, so as to compensate for the height difference of the glue caused by taking out a piece of glue each time, so that the height of the uppermost layer of glue on the load-bearing plate is always maintained unchanged, thereby accurately controlling the glue taking out The material height is ensured to ensure the accuracy of adhesive backing material picking; and the four push rods that pass through the bottom plate of the movable material box assembly upwards can not only play the role of lifting the load-bearing plate, but also effectively limit the bottom plate, ensuring its position stability in the installation slide groove, avoiding position displacement caused by actions such as material picking, thereby ensuring the accuracy of the adhesive backing position; in the process of taking and placing materials, the four push rods pass through the through holes opened on the load-bearing support plate and the bottom plate to support the load-bearing plate upward, and are detachably connected and fixed with the four adsorption blocks at the bottom of the load-bearing plate (the adsorption blocks can be magnetic blocks, which adsorb the push rods by magnetic force); when the material in the material box space is taken out, the push rod descends, and after separating from the adsorption block, it descends downward from the through hole to the bottom of the load-bearing support plate to avoid movement interference when sliding in or pulling out the movable material box assembly. The present invention uses a conveying mechanism arranged on the side of the movable material box component as a material picking execution component. After the conveying mechanism takes out the adhesive sheet from the material box space piece by piece, it performs multi-piece inspection at the multi-piece inspection component. The qualified materials are conveyed to the film tearing component, and the film tearing component clamps the protective film at the bottom of the suspended and adsorbed adhesive sheet and then tears it downward; the adhesive sheet after film tearing is further conveyed to the transfer platform by the conveying mechanism and placed on the transfer platform for transfer or shooting positioning and other actions. At the same time, the transfer platform includes a transfer motor with the output end vertically upwardly arranged, and the position or angle of the adhesive sheet placed thereon can be fine-tuned and corrected by the transfer motor to ensure its position accuracy when it is attached to the back cover of the mobile phone.

[0032] Thirdly, in order to solve the problem of sticking adhesive on the back cover of a mobile phone, the present invention designs a film sticking mechanism, which includes a sticking platform and a sticking mechanism. The sticking platform is arranged on the front side of the material box mechanism, and the sticking mechanism is arranged on the left side of the material box mechanism. The adhesive on the transfer platform is taken out by the sticking mechanism and then transported to the top of the CCD camera in the front direction, so that the CCD camera can shoot the adsorbed adhesive upward, which is convenient for position correction of the adhesive before sticking. After shooting is completed, the sticking mechanism drives the adhesive to continue to move to the top of the sticking platform in the front direction, and sticks the adhesive to the surface of the back cover of the mobile phone on the sticking platform, thereby completing the automatic sticking of the adhesive.

[0033] Thirdly, a transfer mechanism is designed for the automatic transfer of the two materials, the mobile phone back cover and the adhesive backing, between different mechanisms during the bonding process. The transfer mechanism includes a manipulator, a material receiving and feeding conveying mechanism, a rotating transport mechanism and a transfer platform. The material receiving and feeding conveying mechanism is arranged on the machine platform along the front-to-back direction and is located between the bonding mechanism and the pressure-maintaining platform. A support is provided on the material receiving and feeding conveying mechanism. The support is used to carry the mobile phone back cover before bonding and the mobile phone back cover after bonding, and can drive the mobile phone back cover to move forward and backward through the power provided by the linear module to realize its transfer. After the manipulator takes out the mobile phone back cover to be bonded from the material picking station, it places it on the material receiving and feeding conveying mechanism, which is arranged on the right side of the material receiving and feeding conveying mechanism. The rotating transport mechanism uses the left pick-up plate to absorb the mobile phone back cover on the material receiving and feeding conveying mechanism through the vacuum suction nozzle. At the same time, the pick-up plate on the right side of the rotating transport mechanism absorbs the mobile phone back cover after the back glue is attached from the bonding platform. After the pick-up plates on both sides finish picking up the materials, they are driven by the rotary motor to rotate 180° synchronously. The pick-up plate places the bonded mobile phone back cover on the material receiving and feeding conveying mechanism so that it can be transferred backward to the bottom of the pick-up mechanism of the pressure-keeping and film-tearing mechanism for subsequent pressure-keeping and secondary film-tearing. At the same time, the mobile phone back cover to be bonded is placed on the bonding platform again for the next back glue bonding. In this way, the cycle realizes the automatic transfer of the mobile phone back cover to be bonded and the bonded mobile phone back cover. The transfer platform is set below the transfer mechanism of the pressure-keeping and film-tearing mechanism. After the transfer mechanism transports the mobile phone back cover after pressure-keeping and secondary film-tearing to the transfer platform, the manipulator takes out the mobile phone back cover on the transfer platform and transports it to the material tray that is blocked and lifted at the material taking station until the material trough in the material tray is fully loaded with the bonded mobile phone back cover.

[0034] Finally, the present invention designs a pressure-maintaining film-tearing mechanism to solve the problems of secondary film-tearing and laminating pressure-maintaining after the back cover of the mobile phone is affixed with adhesive. The pressure-maintaining film-tearing mechanism includes a material-picking mechanism, a pressure-maintaining platform, a pressure-maintaining mechanism, a film-tearing mechanism and a transfer mechanism. The pressure-maintaining platform is arranged on the left side of the material-receiving and conveying mechanism, and can move back and forth in a straight line along the front-back direction; a material-picking mechanism, a pressure-maintaining mechanism, a film-tearing mechanism and a transfer mechanism are arranged in sequence from back to front above the pressure-maintaining platform. After the material-receiving and conveying mechanism transfers the laminating back cover of the mobile phone to the bottom of the material-picking mechanism, the material-picking mechanism transports the back cover of the mobile phone to On the pressure-holding platform, the pressure-holding platform drives multiple mobile phone back covers to move forward in a straight line to the bottom of the pressure-holding mechanism, and the pressure-holding mechanism provides downward pressure to compress and pressure-hold the mobile phone back covers; after the pressure-holding is completed, the pressure-holding platform drives the mobile phone back covers to continue to move forward to the bottom of the film-tearing mechanism, and the film-tearing mechanism tears off the protective film on the surface of the back adhesive to complete the secondary film-tearing; the mobile phone back covers after film-tearing are continuously transported forward to the bottom of the transfer mechanism via the pressure-holding platform, and the transfer mechanism carries the mobile phone back covers after the secondary film-tearing to the transfer platform so that the robot can move them back to the material tray.

[0096] Furthermore, the present invention independently develops and designs a method to realize automatic material feeding before laminating the mobile phone back cover and automatic material unloading and storage after laminating by circulating the plate, blocking plate and closing plate, effectively improving the material transfer efficiency, and realizing automatic feeding of adhesive, multi-piece detection, film tearing transfer and automatic laminating, using detachable material change, effectively improving the efficiency of adhesive feeding and laminating, and having laminating and pressure keeping function, effectively ensuring the laminating quality of the mobile phone back cover film tearing, laminating and pressure keeping machine and its laminating and pressure keeping process. The present invention aims to provide a device for realizing automatic laminating of mobile phone back cover adhesive and its automatic laminating, film tearing and pressure keeping process of adhesive, which is applied in the automatic assembly production line of mobile phone auxiliary materials to realize efficient, accurate and high-quality laminating of mobile phone back cover adhesive.Firstly, the present invention designs a material tray circulating feeding part as an actuator for circulating supply and automatic material unloading storage of the back cover of the mobile phone. The material tray circulating feeding part uses a feeding bracket arranged in a straight line as a bearing structure. A tray placing station, a material taking station and a tray closing station are arranged at intervals along the straight line direction on the feeding bracket. Two transmission belts for linearly transmitting the material tray and arranged in parallel at intervals are respectively arranged at the three stations (the two transmission belts are tensioned by tensioning wheels, and the tensioning wheels at both ends of the transmission belts are connected by a transmission shaft. The power output by the motor can be transmitted to the transmission shaft through the transmission belt to drive the transmission shaft to drive the tensioning wheel to rotate. When the tensioning wheel rotates, it drives the two transmission belts to rotate synchronously. The three stations are respectively provided with a tray placing mechanism, a material taking and loading mechanism and a tray closing mechanism, wherein the tray placing mechanism and the tray closing mechanism have the same structure, both of which include a horizontal carrier plate arranged in the middle between the two conveyor belts and supporting plates arranged on the front and rear sides of the two conveyor belts. The horizontal carrier plate is driven by a cylinder to move up and down, and the two supporting plates are driven by a cylinder to move horizontally and linearly above the conveyor belts; at the tray placing station, two supporting plates support multiple trays stacked up and down. When a tray needs to be placed, the stacked trays are supported on the horizontal carrier plate, and the supporting plate is pulled outward, and the horizontal carrier plate drives the tray to drop by a tray thickness. After the distance is reached, the two support plates are horizontally inserted above the bottom material tray to separate the bottom material tray and hold the material tray above it again. The horizontal carrier drives the bottom material tray to continue to descend and place it on the transmission belt. The material tray is linearly transmitted to the material picking station via the transmission belt, and is blocked and lifted by the material picking loading mechanism. The material picking loading mechanism may include a blocking block arranged in the two transmission belts and driven up and down by a cylinder, and a horizontal support plate arranged between the two transmission belts. The horizontal support plate is driven to rise and fall by the cylinder so as to carry and lift the blocked cylinder upward to make it fall off the transmission belt in linear motion so as to The robot takes and places the mobile phone back covers in the material tray; when the mobile phone back covers to be bonded in the material tray are taken out and refilled with the mobile phone back covers after bonding, the material loading mechanism puts the material tray back on the conveyor belt, which is transported to the closing station by the conveyor belt. At the closing station, the closing mechanism stacks the material trays filled with the bonded mobile phone back covers from bottom to top on the pallet one by one in the opposite direction of the placing mechanism; thus, the material tray is used as a carrier, and the material tray is used for cyclic placing, blocking and lifting, taking and placing, and closing and unloading. Batch and automatic cyclic feeding and unloading storage of mobile phone back covers are realized, which effectively improves the feeding efficiency of mobile phone back covers and ensures the continuity of feeding.Secondly, in order to solve the problems of automatic feeding, transfer and film tearing of adhesive backing, the present invention designs a feeding and film tearing mechanism, which includes a material box mechanism for storing film sheets and lifting and feeding, and a transport mechanism for taking film and transporting transfer film sheets; the material box mechanism of the present invention specifically adopts a material box space formed by a movable material box assembly to store multiple pieces of adhesive backing in an up and down stacked manner, and the movable material box assembly is detachably installed in an installation slide groove formed on the bearing support plate of the bearing assembly by a sliding-in installation manner, and is guided and limited during the sliding process by the groove opened on the inner side wall of the limiting strip of the bearing assembly, thereby effectively ensuring the position accuracy during the sliding-in installation, and through the sliding-in movable installation of the movable material box assembly, after the adhesive backing in the material box space is taken out, the movable material box assembly can be directly removed to replace the material, which effectively improves the adhesive backing replacement efficiency and reduces the replacement cost. The movable material box assembly forms a material box space with an opening at the top through a first side plate, a second side plate and a guide rod vertically arranged on the bottom plate, and uses a load-bearing plate that can move freely in the vertical direction as a glue bearing structure. The jacking mechanism arranged under the load-bearing assembly outputs power to simultaneously drive four ejector rods to pass through the load-bearing support plate of the load-bearing assembly and the bottom plate of the movable material box assembly to extend into the material box space, and is detachably connected to the bottom of the load-bearing plate through an adsorption block. The power output by the ejector rod drives the load-bearing plate to synchronously move upwards with the thickness of a piece of glue as the movement distance unit during the material taking process, so as to compensate for the height difference of the glue caused by taking out a piece of glue each time, so that the height of the uppermost layer of glue on the load-bearing plate is always maintained unchanged, thereby accurately controlling the glue taking out The material height is ensured to ensure the accuracy of adhesive backing material picking; and the four push rods that pass through the bottom plate of the movable material box assembly upwards can not only play the role of lifting the load-bearing plate, but also effectively limit the bottom plate, ensuring its position stability in the installation slide groove, avoiding position displacement caused by actions such as material picking, thereby ensuring the accuracy of the adhesive backing position; in the process of taking and placing materials, the four push rods pass through the through holes opened on the load-bearing support plate and the bottom plate to support the load-bearing plate upward, and are detachably connected and fixed with the four adsorption blocks at the bottom of the load-bearing plate (the adsorption blocks can be magnetic blocks, which adsorb the push rods by magnetic force); when the material in the material box space is taken out, the push rod descends, and after separating from the adsorption block, it descends downward from the through hole to the bottom of the load-bearing support plate to avoid movement interference when sliding in or pulling out the movable material box assembly. The present invention uses a conveying mechanism arranged on the side of the movable material box component as a material picking execution component. After the conveying mechanism takes out the adhesive sheet from the material box space piece by piece, it performs multi-piece inspection at the multi-piece inspection component. The qualified materials are conveyed to the film tearing component, and the film tearing component clamps the protective film at the bottom of the suspended and adsorbed adhesive sheet and then tears it downward; the adhesive sheet after film tearing is further conveyed to the transfer platform by the conveying mechanism and placed on the transfer platform for transfer or shooting positioning and other actions. At the same time, the transfer platform includes a transfer motor with the output end vertically upwardly arranged, and the position or angle of the adhesive sheet placed thereon can be fine-tuned and corrected by the transfer motor to ensure its position accuracy when it is attached to the back cover of the mobile phone.Thirdly, in order to solve the problem of sticking adhesive on the back cover of a mobile phone, the present invention designs a film sticking mechanism, which includes a sticking platform and a sticking mechanism. The sticking platform is arranged on the front side of the material box mechanism, and the sticking mechanism is arranged on the left side of the material box mechanism. The adhesive on the transfer platform is taken out by the sticking mechanism and then transported to the top of the CCD camera in the front direction, so that the CCD camera can shoot the adsorbed adhesive upward, which is convenient for position correction of the adhesive before sticking. After shooting is completed, the sticking mechanism drives the adhesive to continue to move to the top of the sticking platform in the front direction, and sticks the adhesive to the surface of the back cover of the mobile phone on the sticking platform, thereby completing the automatic sticking of the adhesive. Thirdly, a transfer mechanism is designed for the automatic transfer of the two materials, the mobile phone back cover and the adhesive backing, between different mechanisms during the bonding process. The transfer mechanism includes a manipulator, a material receiving and feeding conveying mechanism, a rotating transport mechanism and a transfer platform. The material receiving and feeding conveying mechanism is arranged on the machine platform along the front-to-back direction and is located between the bonding mechanism and the pressure-maintaining platform. A support is provided on the material receiving and feeding conveying mechanism. The support is used to carry the mobile phone back cover before bonding and the mobile phone back cover after bonding, and can drive the mobile phone back cover to move forward and backward through the power provided by the linear module to realize its transfer. After the manipulator takes out the mobile phone back cover to be bonded from the material picking station, it places it on the material receiving and feeding conveying mechanism, which is arranged on the right side of the material receiving and feeding conveying mechanism. The rotating transport mechanism uses the left pick-up plate to absorb the mobile phone back cover on the material receiving and feeding conveying mechanism through the vacuum suction nozzle. At the same time, the pick-up plate on the right side of the rotating transport mechanism absorbs the mobile phone back cover after the back glue is attached from the bonding platform. After the pick-up plates on both sides finish picking up the materials, they are driven by the rotary motor to rotate 180° synchronously. The pick-up plate places the bonded mobile phone back cover on the material receiving and feeding conveying mechanism so that it can be transferred backward to the bottom of the pick-up mechanism of the pressure-keeping and film-tearing mechanism for subsequent pressure-keeping and secondary film-tearing. At the same time, the mobile phone back cover to be bonded is placed on the bonding platform again for the next back glue bonding. In this way, the cycle realizes the automatic transfer of the mobile phone back cover to be bonded and the bonded mobile phone back cover. The transfer platform is set below the transfer mechanism of the pressure-keeping and film-tearing mechanism. After the transfer mechanism transports the mobile phone back cover after pressure-keeping and secondary film-tearing to the transfer platform, the manipulator takes out the mobile phone back cover on the transfer platform and transports it to the material tray that is blocked and lifted at the material taking station until the material trough in the material tray is fully loaded with the bonded mobile phone back cover.Finally, the present invention designs a pressure-maintaining film-tearing mechanism to solve the problems of secondary film-tearing and laminating pressure-maintaining after the back cover of the mobile phone is affixed with adhesive. The pressure-maintaining film-tearing mechanism includes a material-picking mechanism, a pressure-maintaining platform, a pressure-maintaining mechanism, a film-tearing mechanism and a transfer mechanism. The pressure-maintaining platform is arranged on the left side of the material-receiving and conveying mechanism, and can move back and forth in a straight line along the front-back direction; a material-picking mechanism, a pressure-maintaining mechanism, a film-tearing mechanism and a transfer mechanism are arranged in sequence from back to front above the pressure-maintaining platform. After the material-receiving and conveying mechanism transfers the laminating back cover of the mobile phone to the bottom of the material-picking mechanism, the material-picking mechanism transports the back cover of the mobile phone to On the pressure-holding platform, the pressure-holding platform drives multiple mobile phone back covers to move forward in a straight line to the bottom of the pressure-holding mechanism, and the pressure-holding mechanism provides downward pressure to compress and pressure-hold the mobile phone back covers; after the pressure-holding is completed, the pressure-holding platform drives the mobile phone back covers to continue to move forward to the bottom of the film-tearing mechanism, and the film-tearing mechanism tears off the protective film on the surface of the back adhesive to complete the secondary film-tearing; the mobile phone back covers after film-tearing are continuously transported forward to the bottom of the transfer mechanism via the pressure-holding platform, and the transfer mechanism carries the mobile phone back covers after the secondary film-tearing to the transfer platform so that the robot can move them back to the material tray.
