Description

Technical Field

[0001] The present invention belongs to the technical field of LED processing and manufacturing, and in particular relates to an automatic stacking and transferring device for a flexible substrate carrier for a Mini-LED filament. Background Art

[0002] The production steps of Mini-LED flexible filament are as follows: S1. Preparation of flexible substrate, select a flexible substrate with a width less than or equal to 0.6mm; S2. Crystal bonding, before the crystal bonding operation, first thaw the low-temperature stored crystal bonding glue; expand the LED chip, add the crystal bonding solder paste to the crystal bonding glue tray; set the operating parameters of the crystal bonding equipment; perform crystal bonding operation through the debugged crystal bonding equipment, first apply the crystal bonding solder paste on the pad of the substrate; fix the LED chip to the flexible substrate; perform reflow soldering and then inspection and testing on the first semi-finished product after crystal bonding; start batch crystal bonding after passing the inspection test; if the inspection test fails, repeat the above steps until the inspection test passes. Then the qualified LED chip is fixed to the flexible substrate through the crystal-fixing solder paste; S3. The first baking, set the furnace temperature of the tunnel furnace; wait for the tunnel furnace to heat up until the furnace temperature reaches the set furnace temperature value; put the semi-finished product with crystal-fixing into the tunnel furnace and perform reflow soldering baking; after the semi-finished product is baked, the semi-finished product is inspected and tested; after the inspection and test are qualified, the semi-finished product with crystal-fixing is batch reflow soldered, and wait for cooling after the reflow soldering is completed; if the inspection and test are unqualified, repeat the above steps until the inspection and test are qualified; the semi-finished product after the reflow soldering is completed is lit up; S4. Glue dispensing, cover the semi-finished product made in step 3 with covering glue; S5. The second baking, put the semi-finished product covered with covering glue into the baking equipment for baking, and obtain the LED flexible filament after baking. The flexible substrate is a copper-clad FPC film, and the LED chip adopts a mini flip-chip LED chip.

[0003] In the existing actual production process, in order to improve production efficiency, the crystal bonding, first baking, glue dispensing, and second baking of the flexible substrate are all completed on the carrier board, and the crystal bonding and glue dispensing are completed by automated equipment. The upstream processing unit adopts the method of clamping and positioning multiple flexible substrates through the carrier board according to the requirements of the automated equipment, and each carrier board clamped with a flexible substrate is stacked by a spacer film. In order to improve space utilization and turnover efficiency, multiple carrier boards are stacked in a turnover frame. However, the current equipment mainly uses manual methods to remove the film from each carrier board one by one and then stack them one by one in the turnover frame. It not only has low work efficiency but also easily damages and contaminates the flexible substrate. Therefore, in order to solve the problems of low efficiency in carrier board film removal and transfer and improving the rapid and reasonable arrangement and stacking of the carrier board of the flexible substrate, it is urgent to invent an automated equipment to solve the above technical problems. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic stacking and transferring device for a flexible substrate carrier for Mini-LED filaments to solve the technical problems raised in the above background technology. The following technical solution is provided: an automatic stacking and transferring device for a flexible substrate carrier for Mini-LED filaments, wherein the device comprises:

[0005] A base, wherein a rib is provided at the rear end of the base;

[0006] The feeding mechanism is arranged on one side of the base, and the feeding mechanism is composed of a turnover assembly and a lifting assembly; the turnover assembly is installed on the base, and multiple carriers are stacked inside the turnover assembly, and multiple groups of flexible substrates are fastened on the carriers, and the carriers are stacked up and down through diaphragms. The turnover assembly rotates horizontally and carries the carriers to the loading position; the lifting assembly is installed on one side of the turnover assembly, and the lifting assembly drives the carriers moved to the loading position to move vertically;

[0007] The film stripping and transferring mechanism is fixedly arranged on one side of the rib plate, and the film stripping and transferring mechanism absorbs the diaphragm between the carrier plates to separate it from the carrier plates, and then transports the carrier plates horizontally;

[0008] A belt transmission assembly is arranged on one side of the film stripping and transferring mechanism, and the belt transmission assembly horizontally transmits the carrier plate from which the diaphragm has been separated;

[0009] The storage assembly is arranged on one side of the belt transmission assembly and is used for collecting the carrier plate of the separated diaphragm.

[0010] In the technical solution, when the flexible substrate is stripped and transferred, the operator first puts the stacked carriers into the turnover assembly in sequence, and starts the turnover assembly, which drives the stacked carriers to rotate;

[0011] Then the lifting component starts, and after the lifting component starts, it drives the carrier plate that has rotated to the loading position to move up in sequence through the screw transmission;

[0012] Then the film stripping and transferring mechanism is started, and the film stripping and transferring mechanism swings back and forth after being started. During the reciprocating motion of the film stripping and transferring mechanism, the diaphragm on the carrier is adsorbed and placed in the middle of the turnover assembly, and the carrier is adsorbed and transported to the belt transmission assembly;

[0013] Finally, the belt drive assembly transports the carrier plates with the diaphragm removed to the storage assembly, at which time the storage assembly starts to collect and transfer the carrier plates in sequence to the upper cavity of the storage box; and when the demolding of any stack of carrier plates in the turnover assembly is completed, the lifting assembly is reset, and the turnover assembly rotates to drive the next stack of carrier plates to repeat the demolding and transportation steps until all the carrier plates in the turnover assembly are demolded and transferred.

[0014] In any of the above technical solutions, further, the turnover component includes:

[0015] A square bracket is fixedly arranged on the upper end surface of the base, a transmission casing is arranged on the upper part of the square bracket, a countersunk hole communicating with the outside is arranged on the upper end wall of the transmission casing, a load-bearing rotating shaft is rotatably arranged in the countersunk hole, a driven gear is arranged at the lower end of the load-bearing rotating shaft, a turnover end motor is arranged on the other side of the upper end wall of the transmission casing, the rotating end of the turnover end motor is connected to the driving gear with power, and the driving gear and the driven gear are externally meshed for transmission.

[0016] Specifically, the turnover component also includes:

[0017] A turntable is fixedly arranged at the upper end surface of the load-bearing shaft, a plurality of square through grooves are evenly arranged inside the turntable, and a storage bracket is provided at the upper end of each square through groove, and the upper and lower stacked carrier plates are placed in the storage bracket, and a plurality of grooves are evenly arranged at the lower end surface of the turntable, and the positions of the grooves and the square through grooves correspond one by one.

[0018] In the technical solution, the countersunk hole is provided to bear all the weight of the turntable, the square through slot and the carrier plates stacked in the storage bracket, and a shoulder-like protrusion structure is provided at the upper end of the driven gear. When the load-bearing shaft and the driven gear rotate, the protrusion is always in close contact with the transmission housing, thereby limiting the freedom of movement of the load-bearing shaft and the driven gear as a whole in the vertical direction.

[0019] The driving gear and the driven gear adopt gear transmission to ensure the accuracy of the load-bearing shaft during rotation, so as to ensure that the square through slot can accurately rotate the stacked un-de-filmed carrier plates to the loading position.

[0020] In any of the above technical solutions, further, a conical cylinder is provided on the other side of the square bracket, a ball is clamped inside the conical cylinder, the upper end of the ball is ejected by a spring, and the upper end of the ball is embedded in a groove on the lower end surface of the turntable.

[0021] In the present technical solution, in order to ensure the accuracy of the rotation of the turntable, the square through slot and the lifting assembly at its lower end are ensured to be aligned vertically; through the arranged ball, when the turntable rotates to a predetermined position, the ball is just embedded in the groove arranged on the lower end surface of the turntable, thereby further accurately adjusting the rotation position of the turntable and avoiding the vertical misalignment between the square through slot and the lifting assembly at the lower end, resulting in the lifting assembly being unable to extend upward from the square through slot normally.

[0022] In any of the above technical solutions, further, the lifting component includes:

[0023] A lifting cylinder, wherein a top plate is fixedly provided at the upper end of the lifting cylinder, slideways are evenly provided on the end wall of the outer ring of the lifting cylinder, a transmission chamber is fixedly provided in the middle of the lifting cylinder, a plum blossom groove is fixedly provided in the middle of the square bracket, and the lifting cylinder vertically slides in the plum blossom groove; an internal thread block is provided at the lower end of the transmission chamber, a lead screw is provided in the middle thereof, the lower end of the lead screw is dynamically connected to the lifting end motor, and the lower end of the lifting end motor is fixedly connected to the base.

[0024] In the present technical solution, the interior of the hexagram groove is in a cross shape and can slide up and down with the slideway, limiting the rotational freedom of the lifting cylinder; when the lifting end motor is started, the lifting end motor drives the lead screw to rotate, and when the lead screw rotates, thread transmission occurs with the internal thread block. At this time, the internal thread block and the lifting cylinder are a whole, thereby forcing the lifting cylinder to extend vertically, driving the top plate on its upper part to extend from the square through groove; when the top plate slowly extends, it pushes the carrier plate stacked in the storage bracket to move continuously upward.

[0025] In any of the above technical solutions, further, the film removal and transfer mechanism includes:

[0026] A driving shaft is rotatably arranged on one side of the rib plate, and a driven shaft is rotatably arranged on the other side of the rib plate. A reciprocating motor is arranged on the rear side of the rib plate, and the driving shaft is connected to the reciprocating motor. Auxiliary pulleys are fixedly arranged at the middle of the driving shaft and the driven shaft respectively, and the auxiliary pulleys rotate synchronously through belts. A swing rod is fixedly arranged on the front side of the driving shaft and the driven shaft, and a cylindrical pin is rotatably arranged on the swing rod. A translation bracket is fixedly arranged on the front side of the cylindrical pin. The translation bracket, the rib plate and the two swing rods form a parallelogram mechanism.

[0027] Specifically, the demolding and reprinting mechanism also includes:

[0028] There are four carrier plate suction cups, which are fixedly arranged on the translation bracket respectively. An auxiliary bracket is provided on one side of the translation bracket, and two diaphragm suction cups are fixedly arranged on the auxiliary bracket; a cylinder assembly is fixedly arranged on the upper end of the rib plate, and the carrier plate suction cup and the diaphragm suction cup are respectively connected to the cylinder assembly through a conduit.

[0029] In this technical solution, the translation bracket, the auxiliary bracket and the driven shaft are connected with the rib plate to form a parallelogram mechanism. When the reciprocating motor rotates, the auxiliary pulley drives the driven shaft to swing through the belt, ensuring that the four-bar mechanism moves more stably and has a faster response rate, and the lower end of the carrier suction cup can contact the four corners of the carrier to adsorb it;

[0030] When the four-bar mechanism drives the translation bracket and the auxiliary bracket to translate as a whole, the swing stroke of the rocker arm is always at the upper end of the plane formed by the axis diameters of the driving shaft and the driven shaft:

[0031] When the translation bracket and the auxiliary bracket swing counterclockwise from the right side to the left side, the carrier suction cup first adsorbs the carrier and transfers it to the belt drive assembly and puts it down; at this time, the diaphragm suction cup just moves to the upper end of the carrier that has not been stripped of the film, and then the lifting assembly moves up to drive the flexible substrate to move up, so that the diaphragm suction cup contacts the diaphragm covering the carrier, and the diaphragm suction cup adsorbs the diaphragm; then the reciprocating motor reverses, and through the formed parallelogram mechanism, the diaphragm suction cup is driven to move in a clockwise arc to the middle of the turntable with the adsorbed diaphragm, and the diaphragm suction cup jets out to detach the diaphragm from the stack in the middle of the turntable, and at this time, the carrier suction cup just moves to the carrier that has been stripped of the film and adsorbs the carrier.

[0032] In any of the above technical solutions, further, the belt transmission assembly includes:

[0033] A pulley motor, the front end power of the pulley motor is connected to the second pulley, and a transmission belt is sleeved on the second pulley.

[0034] In the technical solution, the belt drive assembly cooperates with the film stripping transfer mechanism and the storage assembly through the belt drive to transport the film stripped carrier plate transferred from the film stripping transfer mechanism to the storage assembly.

[0035] In any of the above technical solutions, further, the storage component includes:

[0036] A storage box is fixedly arranged on the rib plate, and a storage box is slidably arranged inside. A vertical plate is also fixedly arranged on one side of the base. A vertical slide is arranged on the rear side wall of the vertical plate, and a movable support plate is slidably arranged on the vertical slide. The storage box is placed on the upper end of the movable support plate, and a vertical hydraulic rod is arranged on the lower end of the movable support plate. The lower end of the vertical hydraulic rod is fixedly arranged on the base, and the vertical hydraulic rod drives the movable support plate to slide up and down; and a horizontal hydraulic rod is arranged on one side of the vertical plate.

[0037] In the technical solution, the storage box is provided with an upper and lower through cavity, and a slide rail is provided at the lower end of the through cavity, and a plurality of storage slots are provided inside the storage box, wherein when the belt transmission assembly continuously transports the carrier plate that has been stripped of the film, the carrier plate enters the storage slot of the storage box through the belt transmission assembly, and then the vertical hydraulic rod drives the storage slot to continuously move upward, and sequentially stores the carrier plate that has been stripped of the film in the storage slot of the storage box from top to bottom; when the storage box is completely stored, the vertical hydraulic rod moves to the maximum stroke, and then the horizontal hydraulic rod is started to push the storage box into the upper through cavity of the storage box; finally, the vertical hydraulic rod drives the movable pallet to reset, and the storage box is placed on the movable pallet again at this time;

[0038] The horizontal conveying carrier plate of the belt transmission assembly is located in the middle of the storage box. As the initial position of the storage box placed on the movable support plate rises, the storage slots of the storage box are filled with the stripped carrier plates from top to bottom in sequence.

[0039] An operating method of an automatic stacking and transferring device for a flexible substrate carrier for Mini-LED filaments:

[0040] S1: Place the carriers stacked by the diaphragm into the storage bracket one by one, and then start the turnover end motor, which drives the stacked carriers to rotate to the loading position;

[0041] S2: When the carrier plate rotates to the loading position, the lifting assembly starts to drive the top plate to rise through the screw transmission, and the top plate rises and passes through the square slot to lift the base plate in turn;

[0042] S3: The film stripping and transferring mechanism is started, and the reciprocating motor drives the translation bracket and the carrier plate suction cup to swing back and forth. During the reciprocating motion of the film stripping and transferring mechanism, the diaphragm suction cup absorbs the diaphragm on the carrier plate and places it in the middle of the turntable, and the carrier plate suction cup absorbs the carrier plate and transports it to the belt transmission assembly;

[0043] S4: The belt transmission assembly transports the carrier plate with the diaphragm removed to the storage assembly, and the storage assembly starts to collect the carrier plates one by one and transfer them to the storage box;

[0044] S5: When the carriers in the storage bracket are completely stripped, the lifting assembly is reset, and the turnover assembly rotates to drive the next stack of carriers to repeat steps S2 and S3 until all the carriers in the turnover assembly are stripped and transferred.

[0045] In this technical solution, the transmission parameters of all motor transmission ends are uniformly controlled by one terminal, and the parameters of each transmission end need to be actually debugged on-site by the operator to ensure the continuity and smoothness of the operation of the entire device.

[0046] The beneficial effects of the present invention are as follows: by setting up a feeding mechanism, storage brackets are evenly set up on the turnover component, and the placement of the carrier is preliminarily realized; when the flexible carrier is stripped of the film, a stripping and transfer mechanism is set up, in which the translation bracket, the auxiliary bracket and the driven shaft are connected to the rib plate to form a parallelogram mechanism, and through the reciprocating motion of the parallelogram mechanism, the film on the carrier is first separated and then the stripped carrier is transferred, and at the same time of stripping, the lifting component is linked to the turnover component to lift the coated carrier to the stripping and transfer position in turn, so that the operation of the entire device is continuous, and the device can realize full-automatic stripping, transfer and storage of the carrier.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0068] like Figure 1-2 As shown, this embodiment provides an automatic stacking and transferring device for a flexible substrate carrier for Mini-LED filaments, wherein the device includes:

[0069] A base 100, wherein a rib plate 101 is provided at the rear end of the base 100;

[0070] The feeding mechanism 200 is arranged on one side of the base 100, and the feeding mechanism 200 is composed of a turnover assembly 300 and a lifting assembly 400; the turnover assembly 300 is dynamically installed on the base 100, and a plurality of carrier plates are stacked inside the turnover assembly 300, and a plurality of groups of flexible substrates are fastened on the carrier plates, and the carrier plates are stacked up and down through a diaphragm, and the turnover assembly 300 rotates horizontally to carry the carrier plates to the loading position; the lifting assembly 400 is installed on one side of the turnover assembly 300, and the lifting assembly 400 drives the carrier plates moved to the loading position to move vertically and horizontally;

[0071] The film stripping and transferring mechanism 500 is fixedly arranged on one side of the rib plate 101. The film stripping and transferring mechanism 500 absorbs the membrane between the carrier plates to separate it from the carrier plates, and then transports the carrier plates horizontally.

[0072] The belt transmission assembly 600 is arranged on one side of the film stripping and transferring mechanism 500, and the belt transmission assembly 600 horizontally transmits the carrier plate from which the diaphragm has been separated;

[0073] The storage assembly 700 is disposed on one side of the belt transmission assembly 600 and is used to collect the carrier plate from which the diaphragms have been separated.

[0074] In the technical solution, when the flexible substrate is stripped and transferred, the operator first puts the stacked carriers into the turnover assembly 300 in sequence, and starts the turnover assembly 300, which drives the stacked carriers to rotate;

[0075] When the carrier plate rotates to the loading position, the lifting assembly 400 is started. After the lifting assembly 400 is started, the carrier plate that has rotated to the loading position is driven to move upward in sequence through the screw transmission;

[0076] Then the film stripping and transferring mechanism 500 is started, and the film stripping and transferring mechanism 500 swings back and forth after being started. During the reciprocating motion of the film stripping and transferring mechanism 500, the diaphragm on the carrier is adsorbed and placed in the middle of the turnover assembly 300, and the carrier is adsorbed and transported to the belt transmission assembly 600;

[0077] Finally, the belt transmission component 600 transports the carrier plate with the diaphragm removed to the storage component 700. At this time, the storage component 700 starts to collect and transfer the carrier plates in sequence to the upper through cavity of the storage box 701; and when the demolding of any stack of carrier plates in the turnover component 300 is completed, the lifting component 400 is reset, and the turnover component 300 rotates to drive the next stack of carrier plates to repeat the demolding and transportation steps until all the carrier plates in the turnover component 300 are demolded and transferred. When the carrier plates are stacked up and down, a layer of diaphragm is placed between the carrier plates to ensure that the upper and lower carrier plates will not stick together during transportation, and also to ensure that the filaments fastened on the carrier plates will not be contaminated; when the stacked carrier plates are rotated to be aligned with the demolding transfer mechanism 500, the transfer position at this time is called the loading position. Only when the transfer position is aligned with the demolding transfer mechanism 500 can the formation of the lifting component 400 and the turnover component 300 be guaranteed not to interfere.

[0078] like Figure 5 , 6 As shown in , 7 and 11, specifically, the turnover assembly 300 includes:

[0079] A square bracket 301 is fixedly arranged on the upper end surface of the base 100. A transmission housing 302 is arranged on the upper part of the square bracket 301. A countersunk hole 303 communicating with the outside is arranged on the upper end wall of the transmission housing 302. A load-bearing rotating shaft 304 is rotatably arranged in the countersunk hole 303. A driven gear 305 is arranged at the lower end of the load-bearing rotating shaft 304. A turnover end motor 306 is arranged on the other side of the upper end wall of the transmission housing 302. The rotating end of the turnover end motor 306 is connected to a driving gear 307 by power, and the driving gear 307 and the driven gear 305 are externally meshed for transmission.

[0080] Specifically, the turnover assembly 300 further includes:

[0081] The turntable 308 is fixedly arranged at the upper end surface of the load-bearing shaft 304, and a plurality of square through grooves 310 are evenly arranged inside the turntable 308, and a storage bracket 309 is provided at the upper end of each square through groove 310, and the upper and lower stacked carrier plates are placed in the storage bracket 309, and a plurality of grooves are evenly arranged at the lower end surface of the turntable 308, and the positions of the grooves and the square through grooves 310 correspond one by one.

[0082] In the present technical solution, the countersunk hole 303 is provided to bear all the weight of the rotating disk 308, the square through slot 310 and the carrier plates stacked in the storage bracket 309, and a shoulder-like protrusion structure is provided at the upper end of the driven gear 305. When the load-bearing rotating shaft 304 and the driven gear 305 rotate, the protrusion is always in close contact with the transmission housing 302, thereby limiting the freedom of movement of the load-bearing rotating shaft 304 and the driven gear 305 as a whole in the vertical direction;

[0083] The driving gear 307 and the driven gear 305 adopt gear transmission to ensure the accuracy of the load-bearing shaft 304 during rotation, thereby ensuring that the square through slot 310 can accurately rotate the stacked unde-filmed carrier plates to the loading position.

[0084] like Figure 5 As shown, specifically, a conical cylinder 311 is provided on the other side of the square bracket 301 , and a ball 312 is clamped inside the conical cylinder 311 . The upper end of the ball 312 is ejected by a spring, and the upper end of the ball 312 is embedded in a groove on the lower end surface of the turntable 308 .

[0085] In the present technical solution, in order to ensure the accuracy of the rotation of the turntable 308, the square through slot 310 and the lifting assembly 400 at its lower end are ensured to be aligned vertically; by means of the provided ball 312, when the turntable 308 rotates to a predetermined position, the ball 312 just fits into the groove provided on the lower end surface of the turntable 308, thereby further accurately adjusting the rotation position of the turntable 308 and avoiding the vertical misalignment between the square through slot 310 and the lifting assembly 400 at the lower end, resulting in the lifting assembly 400 being unable to extend upward from the square through slot 310 normally.

[0086] In a preferred embodiment of the present invention:

[0087] like Figure 8-10 As shown, specifically, the lifting assembly 400 includes:

[0088] A lifting cylinder 402, a top plate 408 is fixedly provided at the upper end of the lifting cylinder 402, slideways 403 are evenly provided on the outer ring end wall of the lifting cylinder 402, a transmission chamber 404 is fixedly provided in the middle of the lifting cylinder 402, a plum blossom groove 401 is fixedly provided in the middle of the square bracket 301, and the lifting cylinder 402 slides vertically in the plum blossom groove 401; an internal thread block 405 is fixedly provided at the lower end of the transmission chamber 404, a screw 406 is threadedly connected in the internal thread block 405, the lower end of the screw 406 is poweredly connected to the lifting end motor 407, and the lower end of the lifting end motor 407 is fixedly connected to the base 100.

[0089] In the present technical solution, the interior of the hexagram groove 401 is in a cross shape and can slide up and down with the slideway 403, limiting the rotational freedom of the lifting cylinder 402; when the lifting end motor 407 is started, the lifting end motor 407 drives the lead screw 406 to rotate, and when the lead screw 406 rotates, it undergoes threaded transmission with the internal thread block 405. At this time, the internal thread block 405 and the lifting cylinder 402 are a whole, thereby forcing the lifting cylinder 402 to extend vertically, driving the top plate 408 on its upper part to extend from the square through groove 310; when the top plate 408 slowly extends, it pushes the carrier plate stacked in the storage bracket 309 to move upward continuously.

[0090] In a preferred embodiment of the present invention:

[0091] like Figure 3-4 As shown, specifically, the film stripping and transferring mechanism 500 includes:

[0092] A driving shaft 501 is rotatably arranged on one side of the rib plate 101, and a driven shaft 502 is rotatably arranged on the other side of the rib plate 101. A reciprocating motor 503 is arranged on the rear side of the rib plate 101, and the driving shaft 501 is connected to the reciprocating motor 503 by power. Auxiliary pulleys 504 are fixedly arranged at the middle of the driving shaft 501 and the driven shaft 502, respectively, and the auxiliary pulleys 504 rotate synchronously through belts 505. A swing rod 506 is fixedly arranged on the front side of the driving shaft 501 and the driven shaft 502, and a cylindrical pin 507 is rotatably arranged on the swing rod 506. A translation bracket 508 is fixedly arranged on the front side of the cylindrical pin 507. The translation bracket 508, the rib plate 101 and the two swing rods 506 form a parallelogram mechanism;

[0093] Specifically, the film stripping and transferring mechanism 500 further includes:

[0094] There are four carrier suction cups 509, which are fixedly arranged on the translation bracket 508 respectively. An auxiliary bracket 510 is provided on one side of the translation bracket 508, and two diaphragm suction cups 511 are fixedly arranged on the auxiliary bracket 510; a cylinder assembly 512 is fixedly arranged on the upper end of the rib plate 101, and the carrier suction cup 509 and the diaphragm suction cup 511 are respectively connected to the cylinder assembly 512 through a conduit.

[0095] In the present technical solution, the translation bracket 508, the auxiliary bracket 510 and the driven shaft 502 are connected with the rib plate 101 to form a parallelogram mechanism. When the reciprocating motor 503 rotates, the auxiliary pulley 504 drives the driven shaft 502 to swing through the belt 505, ensuring that the four-bar mechanism moves more stably and has a faster response rate, and the lower end of the carrier suction cup 509 can contact the four corners of the carrier to adsorb it.

[0096] When the four-bar mechanism drives the translation support 508 and the auxiliary support 510 to translate as a whole, the swing stroke of the swing rod 506 is always at the upper end of the plane formed by the axis diameters of the driving shaft 501 and the driven shaft 502:

[0097] When the translation support 508 and the auxiliary support 510 swing counterclockwise from the right side to the left side, the carrier suction cup 509 first absorbs the carrier and transfers it to the belt transmission assembly 600 and puts it down; at this time, the diaphragm suction cup 511 just moves to the upper end of the carrier that has not been stripped of the film, and then the lifting assembly 400 moves up to drive the flexible substrate to move up, so that the diaphragm suction cup 511 contacts the diaphragm covering the carrier, and the diaphragm suction cup 511 absorbs the diaphragm; then the reciprocating motor 503 reverses, and through the formed parallelogram mechanism, the diaphragm suction cup 511 and the absorbed diaphragm move in a clockwise arc to the middle of the turntable 308, and the diaphragm suction cup 511 sprays air to detach the diaphragm from the middle position of the turntable 308, and at this time, the carrier suction cup 509 just moves to the carrier that has been stripped of the film and absorbs the carrier.

[0098] In a preferred embodiment of the present invention:

[0101] In the present technical solution, the belt drive assembly 600 cooperates with the film stripping and transfer mechanism 500 and the storage assembly 700 through belt drive to transport the film stripped carrier plate transferred from the film stripping and transfer mechanism 500 to the storage assembly 700.

[0102] In a preferred embodiment of the present invention:

[0103] like Figure 1-2 As shown, specifically, the storage assembly 700 includes:

[0104] A storage box 701 is fixedly arranged on the rib plate 101, and a storage box 707 is slidably arranged inside the storage box 701. A vertical plate 702 is also fixedly arranged on one side of the base 100. A vertical slide groove 704 is arranged at the rear side wall of the vertical plate 702. A movable support plate 705 is slidably arranged on the vertical slide groove 704. The upper end of the movable support plate 705 supports the storage box 707. A vertical hydraulic rod 706 is arranged at the lower end of the movable support plate 705. The lower end of the vertical hydraulic rod 706 is fixedly arranged on the base 100, and the vertical hydraulic rod 706 drives the movable support plate 705 to slide up and down; and a horizontal hydraulic rod 703 is arranged on one side of the vertical plate 702.

[0105] In the present technical solution, the storage box 701 is provided with an upper and lower through cavity, and a slide rail is provided at the lower end of the through cavity, and a plurality of storage slots are provided inside the storage box 707, wherein when the belt transmission assembly 600 continuously transports the carrier plate that has been stripped of the film, the carrier plate enters the storage slot of the storage box 707 through the belt transmission assembly 600, and then the vertical hydraulic rod 706 drives the storage slot to continuously move upward, and sequentially stores the carrier plate that has been stripped of the film in the storage slot of the storage box 707 from top to bottom; when the storage box 707 has been stored, the vertical hydraulic rod 706 moves to the maximum stroke, and then the horizontal hydraulic rod 703 starts to push the storage box 707 into the upper through cavity of the storage box 701; finally, the vertical hydraulic rod 706 drives the movable support plate 705 to reset, and at this time, the storage box 707 is placed on the movable support plate 705 again;

[0106] The horizontal conveying carrier plate of the belt transmission assembly 600 is located in the middle of the storage box 701. As the initial position of the storage box 707 placed on the movable support plate 705 rises, the storage slots of the storage box 707 are filled with the demolded carrier plates from top to bottom.

[0110] S3: The film stripping and transferring mechanism 500 is started, and the reciprocating motor 503 drives the translation support 508 and the carrier plate suction cup 509 to swing back and forth. During the reciprocating motion of the film stripping and transferring mechanism 500, the diaphragm suction cup 511 absorbs the diaphragm on the carrier plate and places it in the middle of the turntable 308, and the carrier plate suction cup 509 absorbs the carrier plate and transports it to the belt transmission assembly 600;

[0111] S4: The belt transmission assembly 600 transports the carrier plate with the diaphragm removed to the storage assembly 700. At this time, the storage assembly 700 starts to collect and transfer the carrier plates in sequence to the upper through cavity of the storage box 701.
