Description

Technical Field

[0001] This invention relates to the field of substrate transportation technology, specifically to a substrate conveying device and method for eliminating sliding friction in a pre-applied machine. Background Technology

[0002] Pre-applied machines are equipment used for the automated application of materials such as tapes and dry films. They are widely used in fields such as electronics manufacturing and automated production, and are characterized by high efficiency and precision.

[0003] During substrate conveying, the substrate is usually gripped by a robotic arm and transferred onto a conveyor belt. However, when the robotic arm is released, since the initial velocity of the substrate is zero, the acceleration of the substrate depends on the static friction between it and the conveyor belt. If the static friction is insufficient, relative sliding will occur between the substrate and the conveyor belt, which will lead to friction on the surface of the substrate.

[0004] To address this, the substrate and conveyor belt can be kept moving at the same speed during substrate transfer to compensate for the inertia and static friction. However, even if the substrate is kept at the same speed as the conveyor belt before release, there is still a possibility that the speed between the substrate and the conveyor belt will deviate due to the sudden removal of the force during release, and that elastic vibrations will occur when the substrate and the conveyor belt are in contact, which will lead to friction on the surface of the substrate. Summary of the Invention

[0005] The purpose of this invention is to provide a substrate conveying device and a substrate conveying method for a pre-applied machine that eliminates sliding friction, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a substrate conveying device for a pre-applied machine that eliminates sliding friction, comprising: a conveyor table, and transmission rods rotatably mounted on the conveyor table and symmetrically arranged, a first roller fixed on the transmission rod, and a support platform fixed on the conveyor table; further comprising: a synchronous transmission assembly, disposed on the conveyor table and connected to the support platform, including a conveyor belt; a lifting and adsorption mechanism, disposed on the conveyor belt, the lifting and adsorption mechanism being connected to a connecting plate and symmetrically arranged suction cups, the lifting and adsorption mechanism being used to adjust the height of the suction cups to perform adsorption and release actions on the substrate; and a multi-directional limiting mechanism, disposed on the lifting and adsorption mechanism, the multi-directional limiting mechanism being able to perform limiting and ejection actions on the substrate when the lifting and adsorption mechanism moves.

[0007] As a further aspect of the present invention: the synchronous transmission assembly includes a first rotating rod and a second rotating rod rotatably mounted on the support platform, a pulley fixed on the second rotating rod, a conveyor belt sleeved on the pulley, and a belt connected to the transmission rod sleeved on the first rotating rod; it also includes a first gear and a second gear respectively fixed on the first rotating rod and the second rotating rod, the first gear meshing with the second gear.

[0008] As a further embodiment of the present invention: the lifting and adsorption mechanism includes a support sleeve fixed on the conveyor belt, a support rod axially sliding inside the support sleeve, an air storage box fixed at the end of the support rod, and the air storage box being fixedly connected to the suction cup; it also includes a sliding component and a guiding component disposed on the support platform for controlling the support rod to slide axially along the support sleeve.

[0009] As a further embodiment of the present invention: the sliding assembly includes a first through groove formed on the outer circumference of the support sleeve, a movable plate fixed on the support rod and slidably connected to the first through groove, a limit post fixed on the movable plate, and the movable plate being fixedly connected to the connecting plate.

[0010] As a further embodiment of the present invention: the guiding component includes a side plate fixed on the support platform, and a guide groove is formed on the side plate to slide and engage with the limiting post.

[0011] As a further embodiment of the present invention: the multi-directional limiting mechanism includes a fixed sleeve fixedly mounted on the connecting plate and symmetrically arranged, a movable rod axially sliding inside the fixed sleeve, and an upper pressure plate fixed to the end of the movable rod; it also includes an elastic component and a swing component disposed on the fixed sleeve for lateral limiting of the substrate.

[0012] As a further embodiment of the present invention: the elastic component includes a second through groove formed on the outer circumference of the fixed sleeve, a limiting ring fixed on the movable rod and slidably connected to the second through groove, and a spring sleeved on the fixed sleeve, the two ends of the spring respectively abutting against the limiting ring and the connecting plate.

[0013] As a further embodiment of the present invention: the oscillation assembly includes a side baffle rotatably mounted on the side of the upper pressure plate, a fixing ring fixed on the fixing sleeve, and a connecting rod hinged to the side baffle on the fixing ring.

[0014] As a further embodiment of the present invention: a first slot and a second slot are formed on the side baffle, and a first limiting plate and a second limiting plate are fixed on the upper pressure plate, which respectively abut against and cooperate with the first slot and the second slot.

[0015] A substrate conveying method for a pre-applied machine that eliminates sliding friction includes the following steps:

[0016] Step 1: Place the substrate at the desired suction position on the suction cup, and perform suction and positioning actions on the substrate under the action of the lifting suction mechanism and the multi-directional limiting mechanism;

[0017] Step 2: The transmission rod drives the first roller to move, and the transmission rod also drives the conveyor belt to move through the synchronous transmission component, so that the speed of the first roller and the conveyor belt are consistent;

[0018] Step 3: The conveyor belt controls the movement of the lifting and adsorption mechanism, and controls the substrate to adhere to the first roller through the suction cup. Under the action of the multi-directional limiting mechanism, downward pressure is applied to the substrate.

[0019] Step 4: When the suction cup removes the adsorption force applied to the substrate and gradually moves towards the initial position, the multi-directional limiting mechanism gradually separates from the substrate.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: This application can ensure that the substrate will not be misaligned due to inertia when placed on the first roller by controlling the substrate and the first roller to move synchronously, thus preventing the substrate from rubbing. Specifically, after the suction cup adsorbs the substrate, the lifting and adsorption mechanism controls the substrate to always move at the same speed as the first roller and guides the substrate to adhere to the first roller. When the suction cup removes the adsorption force on the substrate, the multi-directional limiting mechanism provides a certain downward pressure to the substrate to ensure that the substrate will not jump due to sudden release. At the same time, the lateral pushing method ensures that the substrate always moves synchronously with the first roller.

[0021] The upper pressure plate always provides a pushing force to the substrate in the direction of the first roller. Under the action of this pushing force, the slight jumping caused by the air pressure impact on the substrate due to the change of air pressure in the suction cup can be suppressed. Under the action of the side baffle, the substrate can continue to be guided to move at the same speed as the first roller, thereby avoiding the speed deviation caused by the air pressure fluctuation of the substrate, as well as the inertial effect generated by the substrate due to the sudden removal of the adsorption force, which would cause misalignment and friction with the first roller.

[0022] When the suction cup separates from the substrate, the downward pressure provided to the substrate by the upper pressure plate can ensure that the substrate will not vibrate and rub due to the residual adsorption force of the suction cup. At the same time, by controlling the side baffle to flip before separating, it can be ensured that the side baffle will not rub against the side of the substrate, thus ensuring that the substrate is in a friction-free state throughout the entire conveying process.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0037] Please see Figures 1-11 In this embodiment of the invention, a substrate conveying device for eliminating sliding friction in a pre-applied machine includes: a conveyor table 1, and a transmission rod 3 rotatably mounted on the conveyor table 1 and symmetrically arranged, with a first roller 4 fixed on the transmission rod 3 and a support platform 6 fixed on the conveyor table 1; it also includes: a synchronous transmission assembly, disposed on the conveyor table 1 and connected to the support platform 6, including a conveyor belt 12; a lifting and adsorption mechanism, disposed on the conveyor belt 12, with a connecting plate 19 and symmetrically arranged suction cups 17 connected to the lifting and adsorption mechanism, the lifting and adsorption mechanism being used to adjust the height of the suction cups 17 to perform adsorption and release actions on the substrate; and a multi-directional limiting mechanism, disposed on the lifting and adsorption mechanism, the multi-directional limiting mechanism being able to perform limiting and ejection actions on the substrate when the lifting and adsorption mechanism moves.

[0038] Specifically, a motor 2 is fixed on the conveyor table 1, and the output shaft of the motor 2 is connected to one of the transmission rods 3. A second roller 5 is also rotatably mounted on the conveyor table 1. The second roller 5 and the first roller 4 are both composed of multiple rollers and are equidistantly distributed. The second roller 5 and the first roller 4 are staggered. When it is necessary to transport the substrate, the substrate can be placed in a position that cooperates with the suction cup 17 by a robot or other transfer equipment. Under the action of the substrate, the multi-directional limiting mechanism moves to provide a thrust to the substrate in the direction away from the suction cup 17. At the same time, it can also limit the substrate laterally. When it is necessary to transport the substrate, the motor 2 controls the transmission rod 3 to rotate, thereby driving the first roller 4 to move. The transmission rod 3 also drives the conveyor belt 12 to move through the synchronous transmission component, so that the conveyor belt 12 maintains the same speed as the first roller 4 and moves in the opposite direction. The conveyor belt 12 will drive the lifting and adsorption mechanism to move, and under the action of the suction cup 17, the substrate will be flipped to face the suction cup 17. The first roller 4 moves in the same direction and at the same speed as the first roller 4 and the second roller 5. When the substrate moves to the designated position, the lifting and adsorption mechanism will control the substrate to move towards the first roller 4 through the suction cup 17 until the substrate is in contact with the surface of the first roller 4. Since the substrate and the first roller 4 move at the same speed, there will be no friction between the substrate and the first roller 4. At this time, positive pressure can be formed in the suction cup 17, so that the suction cup 17 no longer provides adsorption force to the substrate. Under the action of the multi-directional limiting mechanism, a certain downward pressure is provided to the substrate. At the same time, by pushing laterally, it is ensured that the substrate always moves synchronously with the first roller 4. In this way, it can avoid the slight deceleration of the substrate speed due to air pressure changes when the suction cup 17 releases the substrate, and can continue to provide synchronous pushing force to the substrate after the suction cup 17 releases the substrate, so as to prevent the problem of relative displacement between the substrate and the first roller 4 due to the sudden removal of the force.

[0039] Please see Figures 1-3 , Figure 5 The synchronous transmission assembly includes a first rotating rod 8 and a second rotating rod 10 rotatably mounted on the support platform 6. A pulley is fixed on the second rotating rod 10, and the conveyor belt 12 is sleeved on the pulley. A belt 7 connected to the transmission rod 3 is sleeved on the first rotating rod 8. The assembly also includes a first gear 9 and a second gear 11 fixed on the first rotating rod 8 and the second rotating rod 10, respectively. The first gear 9 meshes with the second gear 11.

[0040] In detail, the circumference of the conveyor belt 12 on the pulley is the same as that of the first roller 4, and the number of teeth of the first gear 9 and the second gear 11 is the same. Under the action of the belt 7, the transmission ratio between the transmission rod 3 and the first rotating rod 8 is 1:1. Therefore, when the motor 2 drives the transmission rod 3 to rotate, it controls the movement of the first roller 4. At the same time, the transmission rod 3 will drive the first rotating rod 8 to rotate at the same speed as the transmission rod 3 through the belt 7. Under the action of the first gear 9 and the second gear 11, the second rotating rod 10 rotates synchronously, and the rotation speed is the same as that of the first rotating rod 8, but the rotation direction is opposite to that of the first rotating rod 8. Under the action of the second rotating rod 10, the conveyor belt 12 is controlled to move through the pulley. The movement speed of the conveyor belt 12 is the same as that of the first roller 4, but the movement direction is opposite to that of the first roller 4. In this way, after the lifting and adsorption mechanism adsorbs the substrate through the suction cup 17, it can control the substrate to move at the same speed as the first roller 4, so as to ensure that no relative displacement occurs when the substrate is in contact with the first roller 4, which would cause the substrate surface to rub.

[0041] Please see Figures 1-3 , Figures 5-9 The lifting and adsorption mechanism includes a support sleeve 14 fixed on the conveyor belt 12, a support rod 15 axially sliding inside the support sleeve 14, an air storage box 16 fixed at the end of the support rod 15, and the air storage box 16 fixedly connected to the suction cup 17; it also includes a sliding component and a guiding component disposed on the support platform 6 for controlling the support rod 15 to slide axially along the support sleeve 14, the sliding component including a first through groove 1401 formed on the outer circumferential wall of the support sleeve 14, a movable plate 18 fixed on the support rod 15 and slidably connected to the first through groove 1401, a limit post 1801 fixed on the movable plate 18, and the movable plate 18 fixedly connected to the connecting plate 19, the guiding component including a side plate 13 fixed on the support platform 6, and a guide groove formed on the side plate 13 that slidably engages with the limit post 1801.

[0042] Please see Figures 1-6 , Figure 10 , Figure 11The multi-directional limiting mechanism includes a fixed sleeve 20 fixedly mounted on the connecting plate 19 and symmetrically arranged, with a movable rod 21 axially sliding inside the fixed sleeve 20, and an upper pressure plate 22 fixed to the end of the movable rod 21; it also includes an elastic component and a swing component disposed on the fixed sleeve 20 for lateral limiting of the substrate, the elastic component including a second through groove 2001 formed on the outer circumferential wall of the fixed sleeve 20, a limiting ring 2101 fixed on the movable rod 21 and slidably connected to the second through groove 2001, and a spring 20 sleeved on the fixed sleeve 20. 6. The two ends of the spring 26 abut against the limiting ring 2101 and the connecting plate 19 respectively. The oscillation assembly includes a side baffle 23 rotatably mounted on the side of the upper pressure plate 22. A fixing ring 24 is fixed on the fixing sleeve 20. A connecting rod 25 hinged to the fixing ring 24 and hinged to the side baffle 23 is connected to the fixing ring 24. A first slot 2301 and a second slot 2302 are formed on the side baffle 23. A first limiting plate 2201 and a second limiting plate 2202 are fixed on the upper pressure plate 22 and respectively abut against the first slot 2301 and the second slot 2302.

[0043] Please see Figure 7Furthermore, the air storage box 16 is fixedly connected to the suction cup 17 and the air pressure inside the suction cup 17 can be adjusted. When the air storage box 16 moves up and down, the suction cup 17 can move synchronously with the air storage box 16. The suction cup 17 has two working positions, namely the loading position and the unloading position. The guide groove can be divided into multiple sections, namely the first guide rail 1301, the arc guide rail 1302, the second guide rail 1303, the inclined guide rail 1304, and the third guide rail 1305. The first guide rail 1301 is the most important section. Starting from the midpoint of the third guide rail 1305, the arc guide rail 1302, the second guide rail 1303, and the inclined guide rail 1304 are symmetrically arranged, with the center of the first guide rail 1301 serving as the loading position and the entire third guide rail 1305 as the unloading position. Initially, the limiting post 1801 is located in the middle of the first guide rail 1301. Under the action of the limiting post 1801, the movable plate 18 is positioned at the end of its stroke, approaching the surface of the conveyor belt 12, so that... The support rod 15 is located at the end of its stroke toward the support sleeve 14. At this time, the support rod 15 will drive the suction cup 17 to minimize the distance between the support sleeve 14 through the air storage box 16. The limiting ring 2101 is located at the end of its stroke on the side of the second through groove 2001 away from the connecting plate 19, so that the distance between the limiting ring 2101 and the connecting plate 19 is maximized. The extension of the spring 26 in its natural state is greater than the maximum distance between the limiting ring 2101 and the connecting plate 19. Therefore, the spring 26 is in a pre-compressed state and always provides the limiting ring 2101 with a thrust in the direction away from the connecting plate 19. The limiting ring 2101 will control the upper pressure plate 22 to be located at the end of its stroke away from the connecting plate 19 through the movable rod 21. Therefore, under the action of the connecting rod 25, the side baffle 23 and the upper pressure plate 22 are in a parallel state. Under the action of the first limiting plate 2201 and the first slot 2301, the angle of the side baffle 23 is ensured to no longer change.

[0044] When the substrate needs to be transported, the substrate can be controlled to abut against the upper pressure plate 22 by a robot or transfer device, and the upper pressure plate 22 can be controlled to move towards the connecting plate 19, thereby driving the movable rod 21 to move, so that the limiting ring 2101 moves along the second through groove 2001 and compresses the spring 26. At the same time, under the action of the connecting rod 25, the side baffle 23 is flipped. When the substrate is attached to the suction cup 17, the side baffle 23 is just flipped to a position perpendicular to the upper pressure plate 22. Under the action of the second limiting plate 2202 and the second slot 2302, the angle of the side baffle 23 no longer changes, and the side of the substrate is limited. Under the action of the air storage box 16, a negative pressure is formed in the suction cup 17 to adsorb and solidify the substrate. Since the suction force provided by the suction cup 17 to the substrate is greater than the elastic thrust of the spring 26, the suction force can overcome the elastic thrust of the spring 26, ensuring that the distance between the substrate and the air storage box 16 does not change. During the adsorption process, the substrate is always in a vertical lifting state. Therefore, when the substrate is attached to the upper pressure plate 22, there is no relative displacement between them, so the substrate will not be subjected to friction. The side baffle 23 is only attached to the side of the substrate and performs a limiting action. The thickness of the side baffle 23 is similar to that of the substrate, ensuring that when the substrate is subsequently placed on the first roller 4 and the second roller 5, the side baffle 23 will not interfere with the first roller 4 and the second roller 5. Therefore, the side baffle 23 will also not rub against the substrate.

[0045] At this time, motor 2 operates, driving transmission rod 3 to rotate, thereby driving the first roller 4 to move. Simultaneously, transmission rod 3 controls the movement of conveyor belt 12 through synchronous transmission assembly. Under the action of conveyor belt 12, support sleeve 14 moves synchronously with conveyor belt 12, thereby controlling the limiting post 1801 to slide along the first guide rail 1301. When the limiting post 1801 moves into one of the arc guide rails 1302, since the rotation center of arc guide rail 1302 and the second rotating rod 10 are on the same axis, the position of support rod 15 within support sleeve 14 will not change. When the limiting post 1801 moves into one of the second guide rails 1303, under the action of suction cup 17, the substrate is flipped to face the first roller 4; please refer to Figure 5Subsequently, the conveyor belt 12 continues to move, causing the limiting post 1801 to enter one of the inclined guide rails 1304. Under the action of the inclined guide rail 1304 and the limiting post 1801, the support rod 15 moves away from the support sleeve 14, thereby driving the suction cup 17 to move through the air storage box 16, thus reducing the distance between the substrate and the first roller 4. When the limiting post 1801 disengages from the inclined guide rail 1304 and enters the third guide rail 1305, the substrate is just in contact with the first roller 4. The suction cup 17 moves to the unloading position. Since the substrate always maintains the same speed as the first roller 4, there is no relative displacement between the substrate and the first roller 4 when they are in contact, thus ensuring that the substrate does not rub against each other. Please refer to [link to relevant documentation]. Figure 6 At this time, under the action of the air storage box 16, a positive pressure is formed in the suction cup 17, so that the suction cup 17 no longer provides adsorption force to the substrate. Under the action of the elastic potential energy of the spring 26, the upper pressure plate 22 always provides a pushing force to the substrate in the direction of the first roller 4. Under the action of this pushing force, the slight jumping caused by the air pressure impact on the substrate due to the air pressure change in the suction cup 17 can be suppressed. Under the action of the side baffle 23, the substrate can continue to be guided to move at the same speed as the first roller 4, thereby avoiding the speed deviation caused by the air pressure fluctuation of the substrate, and the inertial effect generated by the substrate due to the sudden removal of the adsorption force, which causes misalignment and friction with the first roller 4.

[0046] As the substrate continues to move, it will remain stable. When the limiting post 1801 disengages from the third guide rail 1305 and moves into another inclined guide rail 1304, the suction cup 17 will separate from the substrate. At the same time, the spring 26 is released elastically, ensuring that the upper pressure plate 22 remains in contact with the substrate. This avoids the sticking phenomenon that may occur when the suction cup 17 separates from the substrate due to intermolecular forces and residual electrostatic adhesion, ensuring that the suction cup 17 separates smoothly from the substrate. Simultaneously, the distance between the movable rod 21 and the connecting plate 19 increases, and under the action of the connecting rod 25... The side baffle 23 is tilted away from the side of the substrate until the side baffle 23 is parallel to the upper pressure plate 22 again. The limiting ring 2101 returns to the end of its stroke on the side of the second through groove 2001. The fixed sleeve 20 will drive the movable rod 21 to move through the limiting ring 2101, so that the upper pressure plate 22 is separated from the substrate. When the limiting post 1801 moves along the inclined guide rail 1304, the second guide rail 1303, and the arc guide rail 1302, and returns to the first guide rail 1301, the above steps are repeated to achieve frictionless conveying of the substrate.

[0047] Preferably, when the suction cup 17 separates from the substrate, the downward pressure provided to the substrate by the upper pressure plate 22 can ensure that the substrate will not vibrate and rub due to the residual adsorption force of the suction cup 17. At the same time, by controlling the side baffle 23 to flip and then separate, it can be ensured that the side baffle 23 will not rub against the side of the substrate, thereby ensuring that the substrate is in a frictionless state throughout the entire conveying process.

[0048] A substrate conveying method for a pre-applied machine that eliminates sliding friction includes the following steps:

[0049] Step 1: Place the substrate at the desired adsorption position on the suction cup 17, and perform adsorption and positioning actions on the substrate under the action of the lifting adsorption mechanism and the multi-directional limiting mechanism;

[0050] Step 2: The transmission rod 3 drives the first roller 4 to move. The transmission rod 3 also drives the conveyor belt 12 to move through the synchronous transmission component, so that the speed of the first roller 4 and the conveyor belt 12 is consistent.

[0051] Step 3: The conveyor belt 12 controls the movement of the lifting and adsorption mechanism, and controls the substrate to adhere to the first roller 4 through the suction cup 17. Under the action of the multi-directional limiting mechanism, downward pressure is applied to the substrate.

[0052] Step 4: When the suction cup 17 removes the adsorption force applied to the substrate and gradually moves towards the initial position, the multi-directional limiting mechanism gradually separates from the substrate.
