Description

Technical Field

[0001] The present application relates to the technical field of material taking devices, and in particular to a rotary material taking mechanism and a device for quickly taking and placing optical sheets. Background Art

[0002] Optically Clear Adhesive (OCA) is a special adhesive used to bond transparent optical components. Currently, OCA is the best adhesive for touch screens. It is primarily used for bonding materials on touch screens and is one of the key raw materials for touch screens, with capacitive touch sensing capabilities.

[0003] Currently, OCA incoming materials are sheets. In order to achieve automatic production, it is necessary to transport the OCA sheets to the processing equipment through the material picking and unloading device during the production process. Among them, the material picking mechanism in the material picking and unloading device picks up the OCA sheets in the material box and loads them onto the material receiving platform, and then transports them to the processing equipment through the material receiving platform. However, since the loading and unloading processes of the existing material picking mechanism need to be carried out in time, its work efficiency is low. In order to meet the needs of rapid production, two groups of material picking mechanisms need to be set up in the overall equipment, and each group of material picking mechanisms needs to be equipped with two material boxes. While the material picking mechanism is picking up materials from one material box, the other material box can be loaded to meet the needs of uninterrupted production of the equipment. It can be seen that the existing material picking and unloading device needs to have two groups of material picking mechanisms and four material boxes at the same time, which results in a larger overall structure of the material picking and unloading device, and higher production and maintenance costs. Summary of the Invention

[0004] In order to solve the problem that the existing material picking and placing device needs to have two sets of material picking mechanisms and four material boxes at the same time, which results in a larger overall structure of the material picking and placing device and high production and maintenance costs, the present application provides a rotary material picking mechanism and a quick optical sheet picking and placing device.

[0005] The following technical solutions are adopted:

[0006] A rotary material picking mechanism includes: a support base, a rotating component, a servo motor and two carrying arms. The rotating component is rotatably connected to the support base, and the two carrying arms are slidably connected to the rotating component. The servo motor is arranged on the support base. The rotating component includes two film picking slide cylinders. The cylinder shafts of the two film picking slide cylinders are respectively connected to two carrying arms. The two carrying arms are located on the same horizontal straight line. The servo motor drives the rotating component to rotate on the support base, and the rotation of the rotating component drives the two carrying arms to perform synchronous circular motion.

[0007] By adopting the above technical solution, a rotary feeding mechanism has two carrying arms, which can move back and forth between the loading station and the unloading station of the rotary feeding mechanism. When one carrying arm is above the loading station and the other carrying arm is above the unloading station, the two carrying arms can load and unload the optical sheets at the same time, greatly improving the working efficiency of the rotary feeding mechanism. The mechanism structure is relatively simple, does not require two sets of feeding mechanisms, and has low cost.

[0008] Preferably, the transport arm includes a fixed frame, a sliding frame, a vacuum suction cup and a film shaking cylinder.

The vacuum suction cup is used to pick up and place the optical sheet, the vacuum pressure regulating valve is used to adjust the suction force of the vacuum suction cup, and the sheet-shaking cylinder is used to shake up and down quickly when loading to prevent the optical sheets from overlapping.

[0010] Preferably, the transport arm further includes an adjusting bolt, a through hole is provided on the fixing frame, and the adjusting bolt passes through the through hole to connect with the sliding frame.

[0011] By adopting the above technical solution, the adjustment bolts can adjust the distance between the vacuum suction cups, thereby being compatible with the loading and unloading of various optical sheet product sizes.

[0012] A device for quickly taking and placing optical sheets, comprising:

[0013] A feeding mechanism, a pre-alignment platform and a rotary material taking mechanism as described above;

[0014] The feeding mechanism is provided with a loading station, and the rotary material taking mechanism loads materials from the loading station;

[0015] The pre-alignment platform is provided with a material unloading station, and the rotary material-taking mechanism unloads materials from the material unloading station.

[0016] By adopting the above technical solution, the feeding mechanism is used to place the OCA sheet, and the rotating material picking mechanism takes out the OCA sheet from the loading station of the feeding mechanism and places the OCA sheet from the unloading station of the pre-alignment platform. The pre-alignment platform receives the OCA sheet for subsequent processes.

[0017] Preferably, the feeding mechanism includes a guide rail, a base, a translation platform and two material boxes. The base is slidingly connected to the guide rail and the base is arranged on the guide rail. The base is detachably connected to the translation platform and the translation platform is arranged on the base. The two material boxes are arranged on the translation platform, and the two material boxes pass through the loading station.

[0018] By adopting the above technical solution, the material box can be moved on the guide rail, and the two material boxes can be automatically switched, one for feeding and the other for manual feeding. The material box is disassembled and installed on the translation platform, which is convenient for placing optical sheets in the material box, and then convenient for non-stop loading. Optical sheets are placed in the material box. When the material box passes through the loading station of the rotary feeding mechanism, the rotary feeding mechanism can load the optical sheets in the material box. The rotating component on the rotary feeding mechanism can drive the conveying arm to rotate synchronously. Both conveying arms can pass through the loading station. After one conveying arm loads the material, the other conveying arm loads the material in turn. The two receiving platforms of the pre-alignment platform can also pass through the unloading station. Then, both conveying arms can unload the optical sheets from the two receiving platforms in turn. This greatly improves the problem of the overall structure of the device being large, and the production cost and maintenance cost being high.

[0019] Preferably, the material box includes a rib on the side edge and a lifting assembly at the bottom, the rib and the lifting assembly are slidably connected, the bottom of the rib is slidably connected to the translation platform, the rib includes a fixed rib and a movable rib, the movable rib is limited by a direction knob, and a scraper is provided on the top of the movable rib.

[0020] By adopting the above technical solution, optical sheets of different sizes can be placed in the material box and can be limited. The scraper is used to prevent the vacuum suction cup on the transport arm from taking too much when taking out the optical sheet.

[0021] Preferably, a first pair of optical fibers, an air blower, an ion rod and a pull-out handle are provided on the translation platform, and the detection ends of the first pair of optical fibers, the air blower and the ion rod are all aligned with the top of the material box.

[0022] By adopting the above technical solution, the handle can be pulled out to facilitate the placement of the translation platform. The air blower is used to blow the optical sheets apart to reduce the overlap of optical sheets during loading. The lifting assembly is used to lift the optical sheets in the material box to the top of the material box where the first optical fiber detection can detect whether too much is taken when the optical sheets are taken away by the vacuum suction cup on the conveying arm. The scraper is used to prevent the vacuum suction cup on the conveying arm from taking too much when taking the optical sheets. The ion rod eliminates static electricity on the surface of the optical sheet by blowing ion wind, thereby preventing multiple sheets from being taken at one time.

[0024] By adopting the above technical solution, when the second optical fiber detects that the vacuum suction cup absorbs multiple optical sheets, the throwing tray moves to the unloading station and extends to collect the multiple optical sheets, which is helpful to solve the problem of multiple sheets appearing during the loading and unloading process of the device.

[0027] Preferably, a row of pipes and a driving motor are provided on the channel module, and the driving motor drives the channel module to slide along the length direction through the row of pipes, and a transfer motor and a vacuum solenoid valve are provided on the mounting block.

[0028] By adopting the above technical solution, the two receiving platforms can slide through the pipes to the position where the transport arm puts down the optical sheet, that is, the unloading station of the rotary material taking mechanism, so as to load other processing equipment.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. A rotary material picking mechanism has two transport arms, each of which is provided with a vacuum suction cup for picking up and placing optical sheets. The two transport arms can move back and forth between the loading station and the unloading station of the rotary material picking mechanism. When one transport arm is above the loading station, the other transport arm is above the unloading station. Through the cooperation of the two transport arms, the rotary material picking mechanism can simultaneously load and unload optical sheets at the same time, greatly improving the working efficiency of the rotary material picking mechanism. The structure is relatively simple, does not require two sets of material picking mechanisms, and has low cost.

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-5 , further details of this application are given.

[0040] The following describes a device for quickly taking and placing optical sheets in the present application using an embodiment.

[0041] Reference Figure 1 and Figure 2 A device for quickly taking and placing optical sheets comprises a rotary material taking mechanism 1, a feeding mechanism 2, a detection mechanism 3 and a pre-alignment platform 4; the feeding mechanism 2 is used to place OCA sheets, the feeding mechanism 2 is provided with a loading station for feeding the rotary material taking mechanism 1, and the pre-alignment platform 4 is provided with an unloading station for unloading the rotary material taking mechanism 1, then the rotary material taking mechanism 1 takes the OCA sheet from the loading station of the feeding mechanism 2 and places the OCA sheet from the unloading station of the pre-alignment platform 4, and the detection mechanism 3 can pass through the unloading station It is also used to detect whether the rotary material picking mechanism 1 unloads multiple OCA sheets at one time onto the pre-alignment platform 4 during the loading and unloading process; if the detection mechanism 3 detects that the rotary material picking mechanism 1 unloads multiple OCA sheets at one time, the rotary material picking mechanism 1 places the multiple OCA sheets on the detection mechanism 3; if the detection mechanism 3 does not detect that the rotary material picking mechanism 1 unloads multiple OCA sheets at one time, the rotary material picking mechanism 1 places the multiple OCA sheets on the pre-alignment platform 4, and the pre-alignment platform 4 receives the OCA sheets for subsequent processes.

[0042] Reference Figure 1The rotating material picking mechanism 1 includes a support base 13, a rotating component 11, a servo motor 131 and two carrying arms 12. The rotating component 11 is rotatably connected to the support base 13, and the two carrying arms 12 are slidably connected to the rotating component 11. The servo motor 131 is set on the support base 13, and the servo motor 131 drives the rotating component 11 to rotate on the support base 13. The rotating assembly 11 includes two film-picking slide cylinders 111, and the cylinder shafts of the two film-picking slide cylinders 111 are respectively connected to two transport arms 12, and the film-picking slide cylinders 111 are used to adjust the height of the transport arms 12; the two transport arms 12 are located on the same horizontal straight line, and the servo motor 131 drives the rotating assembly 11 to rotate and drives the two transport arms 12 to perform synchronous circular motion; in this way, the two transport arms 12 can be rotated to the loading station and the unloading station. When one transport arm 12 is at the loading station and the other transport arm 12 is at the unloading station, one is loading and the other is unloading, which greatly improves the working efficiency of the rotary material-picking mechanism, has a relatively simple structure, does not require two sets of material-picking mechanisms, and has a low cost.

[0043] Reference Figure 1 The transport arm 12 includes a fixed frame 125, a sliding frame 126, a vacuum suction cup 121, an adjusting bolt 123, and a shaking cylinder 124. The cylinder shaft of the sheet-taking slide cylinder 111 is connected to the fixed frame 125, and the sliding frame 126 is slidably connected to the fixed frame 125. A through hole 122 is opened on the fixed frame 125, and the adjusting bolt 123 passes through the through hole 122 to connect the sliding frame 126. The shaking cylinder 124 is arranged on the sliding frame 126 and is fixedly connected to the sliding frame 126. The shaking cylinder 124 is used to shake up and down quickly when taking materials from the feeding mechanism 2 to prevent OCA sheets from stacking; the vacuum suction cup 121 is fixedly connected to the cylinder shaft of the shaking cylinder 124 away from the fixed frame 125, and is used to take and place OCA sheets. At the same time, the vacuum suction cup 121 is connected to the vacuum source through a vacuum pipeline. A vacuum air pressure valve 132 is provided on the vacuum pipeline. The vacuum air pressure valve 132 is placed on the support seat 13 for adjusting the suction force of the vacuum suction cup 121.

[0044] In this embodiment, the sliding frame 126 is slidably connected to the fixed frame 125, and the vacuum suction cup 121 is set on the sliding frame 126. By adjusting the spacing of the sliding frame 126, the rotary material picking mechanism 1 can pick up and place products of different sizes and weights, greatly improving the utilization rate of the device.

[0045] Reference Figure 2 and Figure 3The feeding mechanism 2 includes a guide rail 23, a base 24, a translation platform 21, and two material boxes 22. The base 24 is slidably connected to the guide rail 23 and is disposed on the guide rail 23. A translation cylinder is disposed at the junction of the base 24 and the guide rail 23. The translation cylinder drives the base to translate and slide. The base 24 is detachably connected to the translation platform 21 and the translation platform 21 is disposed on the base 24. Two material boxes 22 are disposed on the translation platform 21. The two material boxes 22 slide through the guide rail 23 and can both pass through the loading station of the rotary material retrieving mechanism 1, allowing the transport arm 12 to retrieve the OCA sheet from the loading station. In addition, the two material boxes 22 are used to place OCA sheets, one for the rotary material retrieving mechanism 1 to retrieve the material, and the other is on standby for manual placement of OCA sheets. The two material boxes 22 can be switched with each other to achieve non-stop loading.

[0046] Reference Figure 2 and Figure 3 The magazine 22 includes side ribs 221 and a lifting assembly 225 at the bottom. The ribs 221 are arranged in a rectangular shape and form the side walls of the magazine 22. The lifting assembly 225 is slidably connected to the inside of the ribs, forming the bottom of the magazine 22. The OCA sheet is placed on the lifting assembly 225, which slides upward to lift the OCA sheet. The inner sidewalls of the ribs 221 abut against the OCA sheet to position it. The bottom of the ribs 221 is slidably connected to the translation platform 21. The ribs 221 include fixed ribs 2211 and movable ribs 2212. In this embodiment, two opposing sides are fixed ribs 2211, while the remaining two sides are movable ribs 2212. Several movable ribs 2212 penetrate through the elongated through-holes of the lifting assembly 225 and can slide along the length of the elongated through-holes. A direction knob 222 is provided on the translation platform 21. The bottom of the direction knob 222 is connected to the bottom of the movable ribs 2212. The movable ribs 2212 are limited in position by the direction knob 222. The fixed ribs 2211 are used to limit the movement of the magazine 22, facilitating its installation. Thus, the magazine 22 can accommodate a variety of OCA sheets of varying sizes while maintaining good positional control. A scraper 223 is provided on the top of the movable retaining edge 2212. The scraper 223 is made of flexible material. When the rotating material taking mechanism 1 takes out the OCA sheet from the material box 22 in the feeding mechanism 2, the scraper 223 touches the outer edge of the OCA sheet. When multiple OCA sheets overlap, the scraper 223 can separate the OCA stacks one by one, thereby reducing the occurrence of the vacuum suction cup 121 on the conveying arm 12 taking too many OCA sheets when taking out the OCA sheets.

[0047] Reference Figure 2 and Figure 3The translation platform 21 is provided with a first radiating optical fiber 214, an air blower 216, an ion rod 217, and a pull-out handle 218. The pull-out handle facilitates the removal and placement of the translation platform 21. The detection ends of the first radiating optical fiber 214, the air blower 216, and the ion rod 217 are all aligned with the top of the material box 22. The air blower 216 is used to blow away the OCA sheets between the sheets to reduce the situation of overlapping OCA sheets when loading. The ion rod 217 uses ion wind to eliminate static electricity on the surface of the OCA sheets, thereby preventing multiple sheets from being taken at one time. In this way, the lifting assembly 225 is also used to lift the OCA sheets in the material box 22 to the top of the material box 22 where the first radiating optical fiber 214 can detect whether there is too much taken, and to align the detection ends of the air blower 216 and the ion rod 217 with the top of the material box 22 when the OCA sheets are taken away by the vacuum suction cup 121 on the transport arm 12.

[0048] Reference Figure 4 The detection mechanism 3 includes a support rod, a fixed plate 31, a throwing tray 32 and a multi-piece inspection slide cylinder 33. The fixed plate 31 is arranged on the support rod, and the throwing tray 32 is slidably arranged on one side of the fixed plate 31. A conveyor belt and a motor are arranged on the fixed plate. The motor controls the movement of the conveyor belt. The throwing tray 32 is arranged on the conveyor belt, and the motor drives the throwing tray 32 on the conveyor belt to slide. The throwing tray 32 can pass under the unloading station of the rotary material picking mechanism 1 for the conveying arm 12 to place excess OCA sheets. The multi-piece inspection slide cylinder 33 is arranged on the fixed plate 31 and is located on the same side of the throwing tray 32. A second matching optical fiber 34 is fixedly provided on the cylinder shaft of the sheet inspection slide cylinder, which is used to extend and drive the second matching optical fiber 34 to move. The second matching optical fiber 34 is aligned with the unloading station of the rotary material picking mechanism 1 to detect whether there are too many OCA sheets. When the second optical fiber detects that the vacuum suction cup 121 has sucked up multiple OCA sheets, the multi-sheet detection slide cylinder 33 controls the throwing tray 32 to move to the bottom of the unloading station, and extends it to collect multiple OCA sheets, which is helpful to solve the problem of sheet overlap when the rotary material picking mechanism 1 takes and places OCA sheets.

[0049] Reference Figure 5 The pre-alignment platform 4 includes a base plate, two channel modules 41, two material receiving platforms 414 and two mounting blocks 413. The two channel modules 41 are slidably arranged on the base plate, and the sliding directions of the two channel modules 41 are opposite. The two mounting blocks 413 are respectively arranged on the two channel modules 41, and the two material receiving platforms 414 are respectively arranged on the two mounting blocks 413. Both material receiving platforms can pass through the unloading station of the pre-alignment platform 4 for the conveying arm 12 in the rotating material picking mechanism 1 to place the extracted OCA sheet on the material receiving platform 414 for subsequent operations.

[0050] Reference Figure 5The channel module 41 is equipped with a pipe 411 and a drive motor 412. The drive motor 412 drives the channel module 41 to slide along its length through the pipe 411. The two receiving platforms 414 can then slide to the position where the transport arm 12 places the OCA sheet, i.e., the unloading station of the rotary material reclaiming mechanism 1, so that other processing equipment can be loaded. The mounting block 413 is equipped with a transfer motor 4132 and a vacuum solenoid valve 4133. The transfer motor 4132 drives the components on the transfer rotating platform 4131 to adjust the angle of the receiving platform 414. The vacuum solenoid valve 4133 is used to initially position the mounting block 413.

[0051] In this embodiment, OCA sheets are placed in the two material boxes in the feeding mechanism 2, and both material boxes can slide to the loading station of the feeding mechanism 2, and one material box is used to pick up materials from the rotary feeding mechanism 1, and the other is on standby for manual placement of OCA sheets; the rotary feeding mechanism 1 drives the rotating component 11 to rotate through the servo motor 131, and drives the two conveying arms 12 located on the same horizontal line to perform synchronous circular motion; when one conveying arm 12 is located above the loading station, the other conveying arm 12 is located above the unloading station of the pre-alignment platform 4, and the height of the conveying arm can be adjusted by the sheet-taking slide cylinder 111 so that the conveying arm passes through the loading station and the unloading station, and the material receiving platform 414 of the pre-alignment platform 4 can slide through the unloading station, and the rapid optical sheet picking and placing device of this application thus completes the work of loading and unloading synchronously. At the same time, the second emitting optical fiber 34 of the detection mechanism 3 is aligned with the unloading station, which is used to detect whether the rotary feeding mechanism 1 takes too many OCA sheets at the loading station. If too many, when the conveying arm 12 moves from the loading station to the unloading station, the detection mechanism 3 will drive the throwing tray 32 to move to the bottom of the unloading station, so that the conveying arm 12 can place the excess OCA sheets in the throwing tray 32. At this time, the receiving platform 414 of the pre-alignment platform 4 does not need the conveying arm 12 to pass through the unloading station, but only needs to wait for another conveying arm 12 to move from the loading station to the unloading station to catch the OCA single sheet. In addition, in order to prevent stacking as much as possible, the device is also provided with additional components on the feeding mechanism 2 to reduce the occurrence of stacking. The device has high working efficiency, simple operation and low cost.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
