Description

Technical Field

[0001] This application relates to the field of semiconductor assembly film application equipment technology, and in particular to a film application machine feeding device. Background Technology

[0002] In the semiconductor and LED processing and assembly film application process, the loading of substrates and metal frames is usually involved. Traditional loading methods typically rely on manual operation, where the film is fixed to the metal frame, and then the substrate is manually arranged and adhered onto the film.

[0003] With the development of automation technology, some companies have begun to try using semi-automatic equipment for material feeding, but efficiency and accuracy still need to be improved. Advances in automated material feeding technology are of great significance for improving the efficiency of semiconductor and LED production and reducing labor costs. Utility Model Content

[0004] To improve the ease of operation of the feeding device for a laminating machine, this application provides a feeding device for a laminating machine.

[0005] This application provides a feeding device for a film applicator, which adopts the following technical solution: A film laminating machine feeding device includes a chassis, on which a first feeding component for transporting substrates and a second feeding component for transporting frames are mounted. A positioning stage for positioning substrates is mounted on the chassis, and a stop bar for blocking and positioning substrates is movably mounted on the positioning stage. A protective mechanism for protecting substrates is mounted on the positioning stage, and a buffer stage for assembling substrates and frames is mounted on the chassis.

[0006] By adopting the above technical solutions, the first and second feeding components realize independent automated transportation of substrates and frames, eliminating the need for manual feeding and greatly improving operational convenience. The baffles on the positioning table can accurately block and position the substrates transported to the positioning table, ensuring uniform substrate positions and providing a positioning basis for subsequent assembly with the frame. The protection mechanism can protect the substrates during transportation and positioning, reducing collision damage between the substrates and equipment components, thus balancing feeding efficiency and product protection.

[0007] In one specific implementation scheme, a positioning groove is provided on the positioning platform, a sliding sleeve is installed on the positioning platform, a sliding rod is slidably installed on the sliding sleeve, a limiting plate is installed on the positioning platform, the sliding rod passes through the limiting plate and is slidably connected to the limiting plate, a positioning ring is installed on the sliding rod, a first spring is sleeved on the sliding rod, one end of the first spring is connected to the positioning ring, and the other end is connected to the positioning platform, a baffle is installed at the end of the sliding rod away from the sliding sleeve, and the stop bar is installed on the baffle.

[0008] By adopting the above technical solution, the positioning groove provides a space for the substrate to be accommodated, thus achieving the initial positioning of the substrate. When the substrate is pushed to the positioning stage, it contacts the stop bar and pushes the baffle to drive the slide bar to slide along the sliding sleeve. At this time, the first spring is deformed by the compression of the positioning ring. The elastic buffering effect of the spring is used to avoid rigid collision between the substrate and the stop bar. The limiting plate restricts the sliding direction of the slide bar to ensure that the displacement of the stop bar is always along the preset direction, thereby improving the positioning stability. When the pushing force disappears, the restoring force of the first spring drives the slide bar, the baffle and the stop bar to move back, which can calibrate and position the substrate, further improving the positioning accuracy.

[0009] In one specific implementation, the protection mechanism includes a guide rod mounted on the positioning platform. A baffle is slidably mounted on the guide rod. A second spring is sleeved on the guide rod, with one end connected to the baffle and the other end connected to the positioning platform. A slider is slidably mounted on the guide rod and connected to the baffle. A fixed rod is mounted on the positioning platform, and a protective plate is rotatably mounted on the fixed rod. A push rod is hinged to the slider, with the end of the push rod away from the slider hinged to the protective plate. A contact piece for pushing the baffle is mounted on the baffle.

[0010] By adopting the above technical solution, when the substrate pushing distance is too large and the baffle moves excessively, the contact piece on the baffle will push the baffle to slide along the guide rod. The baffle will drive the slider to move synchronously and squeeze the second spring. During the movement of the slider, the push rod will push the protective plate to rotate and rise around the fixed rod to support and lift the substrate, avoiding collision damage to the side wall or corner of the positioning stage due to excessive displacement. When the baffle moves back, the restoring force of the second spring will drive the baffle, slider and push rod to reset. The protective plate will then rotate and fall back, without affecting the subsequent transmission and positioning of the substrate. This realizes the automatic triggering and reset of the protection function without manual intervention.

[0011] In one specific implementation, the positioning platform has a beveled surface, which is located on the side where the substrate slides into the positioning groove.

[0012] By adopting the above technical solution, the beveled surface forms a smooth transition guide structure. When the substrate is pushed from the first feeding component to the positioning stage, it can slide smoothly into the positioning groove along the beveled surface, avoiding direct impact or jamming between the substrate edge and the vertical sidewall of the positioning stage, reducing wear on the substrate edge, and improving the smoothness of the substrate entering the positioning groove, thereby increasing feeding efficiency.

[0013] In one specific implementation, the positioning platform is provided with a clearance hole, which is located at the corner of the positioning groove away from the beveled surface, and the clearance hole communicates with the beveled surface.

[0014] By adopting the above technical solution, the clearance hole can collect and contain dust and impurity particles deposited in the corner of the positioning groove, preventing impurities from accumulating in the corner; if the substrate is slightly offset during the transmission process, the clearance hole can also provide clearance space for the corner of the substrate, preventing the corner of the substrate from making hard contact with the corner of the positioning stage and causing cracks or scratches, further improving the protection effect of the substrate.

[0015] In one specific implementation, the first feeding assembly includes a first mounting frame, a lifting rod slidably mounted on the first mounting frame, a first lifting plate mounted on the lifting rod, a first servo motor for controlling the lifting of the first lifting plate mounted on the first mounting frame, a first loading frame for stacking substrates mounted on the first lifting plate, and a first slot for inserting substrates on the first loading frame; a first slide is mounted on the chassis, and a push plate is connected to the first slide to push the substrates out of the first slots, the push plate pushing the substrates onto the positioning platform.

[0016] By adopting the above technical solution, workers can pre-insert multiple substrates into the first slot of the first loading frame for stacking and storage, reducing frequent loading operations; the first servo motor can precisely control the first lifting plate to drive the first loading frame to rise and fall, so that the substrate to be pushed is always at a height position that matches the push plate; the first slide table drives the push plate to push the substrate out of the first slot and send it to the positioning table, realizing automated continuous loading of substrates, greatly reducing manual labor intensity and improving loading efficiency and accuracy.

[0017] In one specific implementation, the second feeding assembly includes a second slide table mounted on the chassis, a second lifting plate connected to the second slide table, a second loading frame of a stacking frame mounted on the second lifting plate, and a second slot for inserting the frame on the second loading frame.

[0018] By adopting the above technical solution, the second slot of the second loading frame can stack and store the frames. The second slide controls the second lifting plate to drive the second loading frame to rise and fall, which can adjust the height of the frame according to the subsequent material picking needs, providing convenience for the automated picking of the frames, realizing the batch storage and orderly feeding of the frames, and further improving the overall automation level of material feeding.

[0019] In one specific implementation, a first cylinder is mounted on the chassis, the output shaft of the first cylinder is connected to a first slide plate of the receiving frame, a third mounting bracket is mounted on the chassis, a second cylinder is mounted on the third mounting bracket, the second cylinder and the first cylinder are arranged opposite to each other on both sides of the buffer platform, and the output shaft of the second cylinder is connected to a second slide plate of the receiving frame; a robot is mounted on the chassis, the robot is equipped with a suction nozzle for picking up substrates, and a gripper cylinder for gripping the frame is mounted on the robot, the robot controls the gripper cylinder to pull the frame out of the second slot and place it on the first slide plate and the second slide plate.

[0020] By adopting the above technical solution, the robot integrates a suction nozzle and a gripper cylinder, which can simultaneously realize the suction and transfer of the substrate and the gripping and transfer of the frame, without the need for an additional independent material handling mechanism, thus simplifying the equipment structure. The robot takes the frame out of the second slot and places it on the first and second slides. By controlling the first and second slides to descend synchronously through the first and second cylinders respectively, the frame can be accurately placed on the substrate of the buffer platform, realizing the automated assembly and docking of the substrate and the frame, which greatly improves the assembly efficiency and alignment accuracy.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Achieve automated collaborative feeding: Through independently set first and second feeding components, batch storage, automatic transfer and height adjustment of substrates and frames are completed respectively. Combined with the integrated material picking and assembly function of the robot, the manual operation links are greatly reduced, and the convenience and efficiency of feeding and assembly are significantly improved.

[0022] 2. Through the setting of elastic positioning and multi-level protection structure, the baffle bar and the first spring realize the buffer positioning of the substrate to avoid rigid collision; the beveled surface and the avoidance hole reduce the risk of wear during the substrate transportation process; the protection mechanism can automatically trigger support protection when the substrate is excessively displaced, ensuring the substrate quality in multiple dimensions and reducing the defect rate.

[0032] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0033] This application discloses a film applicator feeding device, referring to... Figure 1 and Figure 2 It includes a chassis 1, a first loading assembly 2 for transporting substrates and a second loading assembly 3 for transporting frames mounted on the chassis 1, and a buffer platform 4 for assembling substrates and frames mounted on the chassis 1.

[0034] Reference Figure 1 , Figure 2 and Figure 3The first feeding assembly 2 includes a first mounting frame 21, which is fixedly mounted on the chassis 1. A lifting rod 22 is slidably mounted on the first mounting frame 21. A first lifting plate 23 is fixedly mounted on the lifting rod 22. A lead screw 24 is fixedly mounted on the first lifting plate 23. A first servo motor 25 is fixedly mounted on the first mounting frame 21. A turntable 26 is rotatably mounted on the first mounting frame 21. The first servo motor 25 is connected to the turntable 26 via a synchronous pulley and belt. The first servo motor 25 can control the rotation of the turntable 26. The lead screw 24 passes through the turntable 26 and is threadedly connected to it. When the first servo motor 25 drives the turntable 26 to rotate, the lead screw 24 can move up and down. A first loading frame 27 is fixedly mounted on the first lifting plate 23. The first loading frame 27 has several first slots 271 for accommodating substrates.

[0035] A first slide 281 is fixedly installed on the chassis 1, and a push plate 282 is fixedly connected to the first slide 281. The first slide 281 can control the push plate 282 to move closer to and away from the first loading frame 27. In this embodiment, the first slide 281 is a pneumatic slide. Pneumatic slides are existing technology and will not be described further in this embodiment.

[0036] The operator inserts the substrate into the first slot 271 on the first loading frame 27. The first servo motor 25 controls the lead screw 24 to rotate and rise. The lead screw 24 drives the first lifting plate 23 to rise. The first lifting plate 23 drives the first loading frame 27 to rise, thereby adjusting the height of the substrate. The first slide table 281 controls the push plate 282 to move closer to the first loading frame 27. The push plate 282 pushes the substrate out of the first slot 271.

[0037] Reference Figure 2 and Figure 4 A second mounting bracket 291 is fixedly mounted on the chassis 1. A positioning stage 292 for positioning the substrate is fixedly mounted on the second mounting bracket 291. The positioning stage 292 has a positioning groove 2921 for accommodating the substrate. A chamfered surface 2922 is formed at one end of the positioning stage 292 near the first loading frame 27. A clearance hole 2923 is formed on the positioning stage 292, which communicates with the positioning groove 2921. The clearance hole 2923 is located at the two corners of the positioning groove 2921 away from the chamfered surface 2922.

[0038] After the substrate is pushed out of the first loading frame 27, it will slide into the positioning groove 2921 on the positioning stage 292. A beveled surface 2922 is provided at the end of the positioning stage 292 where the substrate slides in to prevent the substrate from hitting the vertical side wall of the positioning stage 292 and causing damage to the substrate. A clearance hole 2923 is provided on the positioning stage 292 to prevent dust or impurity particles from accumulating in the corners of the positioning stage 292 and to prevent the corners of the substrate from hitting the positioning stage 292 and causing damage to the substrate.

[0039] Reference Figure 4 , Figure 5 and Figure 6 A sliding sleeve 51 is fixedly installed on the positioning platform 292, and a sliding rod 52 is slidably installed on the sliding sleeve 51. A limiting plate 53 is fixedly installed on the positioning platform 292, and the sliding rod 52 passes through the limiting plate 53 and is slidably connected to the limiting plate 53. A positioning ring 54 is fixedly installed on the sliding rod 52, and a first spring 55 is sleeved on the sliding rod 52. One end of the first spring 55 is fixedly connected to the positioning ring 54, and the other end is fixedly connected to the positioning platform 292. A baffle 56 is fixedly installed on the end of the sliding rod 52 away from the sliding sleeve 51, and a stop strip 57 made of rubber is fixedly installed on the baffle 56.

[0040] After the substrate is pushed onto the positioning stage 292, the pusher plate 282 will push the substrate to contact the stop bar 57 and cause the stop bar 57 and the baffle plate 56 to slide into the positioning stage 292 and compress the first spring 55. When the pusher plate 282 retracts, the first spring 55 will push the baffle plate 56 and the stop bar 57 to move with the pusher plate 282. This can be understood as the pusher plate 282 pushing the substrate onto the positioning stage 292 to contact the stop bar 57. The stop bar 57 supports the substrate to prevent the substrate from directly abutting against the side wall of the positioning stage 292 and causing damage due to hard contact. Then the stop bar 57 pushes the substrate back to position the substrate so that the substrates on the positioning stage 292 are on the same straight line.

[0041] Reference Figure 5 and Figure 6 A protective mechanism is installed on the positioning stage 292 to prevent the substrate from colliding with the side wall of the positioning stage 292. The protective mechanism includes a guide rod 581, which is fixedly installed on the positioning stage 292. A baffle 582 is slidably installed on the guide rod 581. A second spring 583 is sleeved on the guide rod 581. One end of the second spring 583 is fixedly connected to the baffle 582, and the other end is fixedly connected to the positioning stage 292. A slider 584 is slidably installed on the guide rod 581. The slider 584 is fixedly connected to the baffle 582 through a connecting rod 585. A fixing rod 586 is fixedly installed on the positioning stage 292. A protective plate 587 is rotatably installed on the fixing rod 586. A push rod 588 is hinged to the slider 584. The end of the push rod 588 away from the slider 584 is hinged to the end of the protective plate 587 away from the fixing rod 586. A contact piece 589 for pushing the baffle 582 is fixedly installed on the side of the baffle 56 away from the baffle bar 57.

[0042] When the substrate pushes the baffle 56 and the baffle 57 to move too far, the contact piece 589 on the baffle 56 will contact the baffle 582 and push the baffle 582 to move. The baffle 582 will pull the slider 584 to slide on the guide rod 581. The slider 584 will drive the push rod 588 to move. The push rod 588 will push the protective piece 587 to rotate on the fixed rod 586. The protective piece 587 will rise to support the substrate and lift the substrate, thereby preventing the substrate from colliding with the positioning stage 292.

[0043] Reference Figure 1 , Figure 7 and Figure 8 The second feeding assembly 3 includes a second slide 31, which is fixedly mounted on the housing 1. In this embodiment, the second slide 31 is an electric slide, which is existing technology and will not be described further in this embodiment. A second lifting plate 32 is fixedly connected to the second slide 31, and the second slide 31 can control the up and down movement of the second lifting plate 32. A second loading frame 33 is fixedly mounted on the second lifting plate 32, and a second slot 331 for inserting an iron frame is provided on the second loading frame 33. A first cylinder 341 is fixedly mounted on the housing 1, and the output shaft of the first cylinder 341 is fixedly connected to a first slide plate 342. A third mounting bracket 351 is fixedly mounted on the housing 1, and a second cylinder 352 is fixedly mounted on the third mounting bracket 351. The second cylinder 352 and the first cylinder 341 are arranged opposite to each other on both sides of the buffer platform 4, and the output shaft of the second cylinder 352 is fixedly connected to a second slide plate 353. A robot 361 is fixedly installed on the chassis 1. In this embodiment of the application, the robot 361 is the prior art. The robot 361 is equipped with a suction nozzle 362 for picking up the substrate. A vacuum generator is connected to the suction nozzle 362. The robot 361 is also equipped with a gripper cylinder 363 for gripping the frame.

[0044] When assembling the substrate and frame, robot 361 controls the suction nozzle 362 to move and pick up the substrate and place it on the buffer stage 4. Then, robot 361 controls the gripper cylinder 363 to grip the frame and pull it out of the second loading frame 33, and place it on the first slide plate 342 and the second slide plate 353. Finally, the first cylinder 341 controls the first slide plate 342 to descend, and the second cylinder 352 controls the second slide plate 353 to descend and place the frame on the substrate.

[0045] The implementation principle of this application embodiment is as follows: The operator inserts multiple substrates into the first slot 271 of the first loading frame 27, and inserts multiple frames into the second slot 331 of the second loading frame 33; after starting the equipment, the first servo motor 25 drives the first lifting plate 23 to lift the first loading frame 27, aligning the substrate to be retrieved with the push plate 282. The first slide 281 drives the push plate 282 to push the substrate into the positioning groove 2921 of the positioning stage 292. The beveled surface 2922 guides the substrate to slide smoothly in, and the clearance hole 2923 prevents damage caused by impurities. When the plate contacts the baffle 57, it pushes the baffle 56 to slide. The first spring 55 buffers the movement and resets its position after the push plate 282 retracts. If the substrate displacement is too large, the contact piece 589 pushes the baffle 582, which in turn raises the protective piece 587 through the slider 584 and the push rod 588. Simultaneously, the second slide table 31 adjusts the height of the second loading frame 33, and the robot 361 picks up the positioned substrate through the suction nozzle 362 to the buffer table 4. The gripper cylinder 363 then grips the frame to the first slide plate 342 and the second slide plate 353. The two cylinders drive the slide plates to descend, thus assembling the substrate and the frame. The entire process achieves automated feeding, positioning, protection, and assembly of the substrate and frame, with convenient operation and good protection effect.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
