Description

Technical Field

[0001] This invention relates to the field of panel handling technology, and more specifically to a feeding device for the production of wood veneer panels. Background Technology

[0002] Wood veneer panels are decorative panels made from solid wood or engineered wood as the base material, processed through veneer, painting, embossing, and other techniques. They combine the texture and feel of natural wood with excellent mechanical properties, and are widely used in furniture manufacturing, interior decoration, and custom furniture. The production process involves multiple steps, including base material cutting, surface treatment, gluing, and curing. The loading stage, as a crucial link between these steps, directly impacts production efficiency and product quality. Currently, loading operations in wood veneer panel production largely rely on a "robotic arm + suction cup" structure for automated handling. This involves installing vacuum suction cups at the end of the robotic arm, which then picks up the panel, moves it above a conveyor roller, releases the suction cup, and places the panel on the conveyor roller, which then transports it to the next process. However, the robotic arm, as the core driving component, has relatively high procurement costs, and its motion trajectory debugging and programming are relatively complex, impacting subsequent operation. The operation and maintenance requirements are high. At the same time, the conveyor rollers need to be kept rotating at all times to ensure continuous production. During the feeding process, when the robotic arm lowers the panel onto the surface of the conveyor rollers, if the suction cups fail to release the suction in time due to delayed vacuum release, such as slow vacuum valve response or residual pressure in the pipeline, the panel will not be able to move synchronously with the conveyor rollers because of the suction cups. This will cause severe sliding friction between the bottom of the panel and the rotating conveyor rollers. Since the wood veneer panel substrate, especially the thin panel, has low hardness, severe friction can easily cause scratches, burrs and other wear defects on the bottom of the panel, which directly affects the appearance quality of the product. It may even cause the panel to be scrapped due to uneven wear. Moreover, when the suction cups are not released in time, the friction force of the conveyor rollers on the bottom of the panel and the suction force of the suction cups on the top of the panel will act in opposite directions. This force will cause local stress concentration on the panel, which may lead to warping, dents and other deformations, further increasing the production rework rate and material costs. In view of this, we propose a feeding device for the production of wood veneer panels. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, this invention provides a feeding device for the production of wood veneer panels. This device effectively solves the problems of existing technologies that rely on robotic arms and suction cups for feeding. These robotic arms are costly, complex to debug and maintain, and may cause severe sliding friction between the panels and the continuously rotating conveyor rollers due to delayed vacuum release from the suction cups. This can result in wear and tear on the bottom of thin panels, or warping and denting due to stress concentration caused by the reverse force, increasing rework rates and material costs.

[0004] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a feeding device for the production of wood veneer panels, including a support frame, comprising, The storage unit includes a support mechanism mounted on a bracket for placing a panel, a lifting mechanism mounted on the support mechanism for adjusting the height of the support mechanism, and a clutch mechanism mounted on the lifting mechanism. The transfer unit includes a fixing mechanism disposed above the support mechanism for adsorbing and fixing the panel, a guide mechanism disposed on the fixing mechanism for limiting the movement path of the fixing mechanism, and a push-pull mechanism disposed on the fixing mechanism. The push-pull mechanism and the guide mechanism can be used to drive the fixing mechanism to move repeatedly in an L-shaped trajectory. The transport unit includes a transport mechanism mounted on a support for transporting panels to a production station, a material support mechanism mounted on the transport mechanism for supporting panels transferred from the fixing mechanism to the transport mechanism and for placing panels on the transport mechanism, and a push-pull mechanism mounted on the material support mechanism for driving the material support mechanism to move up and down repeatedly.

[0005] Furthermore, the support mechanism includes a lower fixed frame fixedly connected to the top of the bracket, multiple sets of telescopic support rods fixedly connected to the top of the lower fixed frame, an upper support plate fixedly connected to the top of the telescopic support rods, and two sets of symmetrically distributed L-shaped positioning plates slidably connected to the inner wall of the upper support plate, with the bottom of the two sets of L-shaped positioning plates fixedly connected to the top of the lower fixed frame.

[0006] Furthermore, the lifting mechanism includes a guide rail fixedly connected to the top of the lower fixed frame, a motor fixedly connected to one side of the guide rail, a bidirectional lead screw fixedly connected to the motor via an output shaft, two sets of symmetrically distributed threaded sleeves connected to the surface of the bidirectional lead screw, the surfaces of the two sets of threaded sleeves being slidably connected to the inner wall of the guide rail, and a top rod rotatably connected to the top of each set of threaded sleeves, the ends of the two sets of top rods away from the threaded sleeves being rotatably connected to the bottom of the upper support plate.

[0007] Furthermore, the clutch mechanism includes a two-way lead screw with an electric telescopic rod fixedly connected to the end away from the motor, and a positioning protrusion fixedly connected to the end of the electric telescopic rod away from the motor. A positioning sleeve is provided at the end of the positioning protrusion away from the electric telescopic rod. A positioning groove is provided on the side of the positioning sleeve near the positioning protrusion for insertion and engagement with the positioning protrusion. A synchronization component is connected to the side of the positioning sleeve away from the positioning protrusion.

[0008] Furthermore, the guiding mechanism includes a guide plate fixedly connected to the top of the bracket, an L-shaped guide groove on the surface of the guide plate, a second guide rail fixedly connected to one side of the guide plate, a sliding plate slidably connected to the inner wall of the second guide rail, and an oblique guide groove on the surface of the sliding plate.

[0009] Furthermore, the fixing mechanism includes an L-shaped guide groove and a limiting roller that slides along the inner wall of the inclined guide groove. A tripod is fixedly connected to one end of the limiting roller, and an I-shaped frame is fixedly connected to the end of the tripod away from the limiting roller. Multiple sets of electric suction cups for adsorbing and fixing the panel are fixedly connected to the bottom of the I-shaped frame.

[0010] Furthermore, the push-pull mechanism 1 includes a crank 1 that is connected to the synchronization component 1 via a synchronization component 2. A connecting rod 1 is rotatably connected to the end of the crank 1 away from the synchronization component 2. The end of the connecting rod 1 away from the crank 1 is rotatably connected to one side of the sliding plate.

[0011] Furthermore, the transport mechanism includes a side frame fixedly connected to the top of the support, and the inner wall of the side frame is rotatably connected to multiple sets of conveyor rollers for transporting the panels to the production station.

[0012] Furthermore, the material support mechanism includes a U-shaped frame fixedly connected to the bottom of the side frame, multiple sets of guide rails are fixedly connected to the inner wall of the U-shaped frame, a material support frame is slidably connected to the guide rails, multiple sets of fixing rods are fixedly connected to the top of the material support frame, and a material support plate is fixedly connected to the top of each set of fixing rods.

[0013] Furthermore, the push-pull mechanism two includes crank two that is connected to crank one via synchronous component two, and crank two is connected to positioning sleeve via synchronous component one. The end of crank two away from synchronization component two and synchronization component one is rotatably connected to connecting rod two, and the end of connecting rod two away from crank two is rotatably connected to one side of the material support frame.

[0014] The technical solution provided by this invention has the following advantages compared with known public technologies: This invention uses a push-pull mechanism to drive a material support mechanism to slowly lower the panel, allowing the panel to contact the continuously rotating conveyor roller at a low speed and smoothly. This avoids relative sliding friction between the panel and the conveyor roller caused by delayed detachment of the suction cup, thus reducing the incidence of wear defects such as scratches and burrs on the bottom of the panel. This effectively improves the appearance quality of the product and reduces the cost of panel scrap due to wear. Furthermore, the material support mechanism provides full support for the panel and smoothly lifts it during the slow lowering process, avoiding the reverse force formed by the suction force of the suction cup and the friction of the conveyor roller during loading. This prevents the panel from warping, denting, or other deformations due to localized stress concentration, further ensuring product quality and significantly reducing material waste and rework time. By adopting a single motor drive combined with mechanical structure linkage, the power of the lifting mechanism is synchronously transmitted to the transfer and transportation units with the help of synchronous components. There is no need to configure drive components for each unit separately, and the complex trajectory debugging and programming process of the robotic arm is eliminated. Only basic components such as motors and synchronous belts need to be maintained in the later stage. At the same time, the L-shaped guide groove and oblique guide groove of the guide mechanism are used to precisely constrain the motion trajectory of the transfer unit, avoiding deviation and collision during panel transfer. The operation and use are simpler, reducing the use and maintenance costs of the device, while further improving the efficiency of product loading and production processing.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] The present invention will be further described below with reference to embodiments.

[0020] like Figures 1 to 10As shown, a feeding device for producing wood veneer panels includes a support frame 100 and a storage unit 200. The storage unit includes a support mechanism 201 mounted on the support frame 100 for placing panels, a lifting mechanism 202 mounted on the support mechanism 201 for adjusting the height of the support mechanism 201, and a clutch mechanism 203 mounted on the lifting mechanism 202. The support mechanism 201 can be used to store panels, while the lifting mechanism 202 mounted on the support mechanism 201 can gradually raise the support mechanism 201 as the panels above it are transferred during the feeding process. 1. Facilitates panel transfer. The clutch mechanism 203 can be used to drive other components to operate synchronously while the lifting mechanism 202 drives the support mechanism 201 to rise. Conversely, when the panels stored on the support mechanism 201 are transferred, the clutch mechanism 203 can disconnect from other components, allowing the lifting mechanism 202 to drive the support mechanism 201 to descend while other components remain in their initial positions. When the support mechanism 201 is reloaded with the next batch of materials, the clutch mechanism 203 can then connect to other related components for the transfer and loading of the second batch of materials. Specifically, the support mechanism 201 includes a lower fixed frame 2011 fixedly connected to the top of the bracket 100. Multiple sets of telescopic support rods 2012 are fixedly connected to the top of the lower fixed frame 2011. An upper support plate 2013 is fixedly connected to the top of each telescopic support rod 2012. Two sets of symmetrically distributed L-shaped positioning plates 2014 are slidably connected to the inner wall of the upper support plate 2013. The bottoms of the two sets of L-shaped positioning plates 2014 are fixedly connected to the top of the lower fixed frame 2011. The lifting mechanism 202 includes a guide rail 2021 fixedly connected to the top of the lower fixed frame 2011. A motor 2022 is fixedly connected to one side of the guide rail 2021. The motor 2022 is connected via an output shaft. A fixed connection is provided with a bidirectional lead screw 2023. The surface of the bidirectional lead screw 2023 is threaded with two sets of symmetrically distributed threaded sleeves 2024. The surfaces of the two sets of threaded sleeves 2024 are slidably connected to the inner wall of the guide rail 2021. The top of each set of threaded sleeves 2024 is rotatably connected to a top rod 2025. The end of each set of top rods 2025 away from the threaded sleeves 2024 is rotatably connected to the bottom of the upper support plate 2013. The upper support plate 2013 can be used to place the panel. With the two sets of L-shaped positioning plates 2014, the two corners of the panel can be positioned when the panel is placed, thereby ensuring that the panel can be stacked neatly when placed on the upper support plate 2013. It should be noted that the output of motor 2022 can drive the bidirectional lead screw 2023 in guide rail 2021 to rotate. The surface of the bidirectional lead screw 2023 has two sets of opposite threads. When the bidirectional lead screw 2023 rotates, the two sets of threaded sleeves 2024 on its surface can move in opposite directions. Thus, the push rod 2025 on the threaded sleeve 2024 can push up the upper support plate 2013 used to store the panel. Conversely, when motor 2022 outputs in the opposite direction, driving the bidirectional lead screw 2023 to rotate in the opposite direction, the threaded sleeve 2024 and the push rod 2025 can push up the upper support plate 2013 used to store the panel. 25 drives the upper support plate 2013 to descend and reset. The multiple sets of telescopic support rods 2012 set on the lower fixed frame 2011 can ensure the stability of the upper support plate 2013 during panel storage and lifting. At the same time, the two sets of L-shaped positioning plates 2014 slidably connected to the upper support plate 2013 can position the panel when it is placed on the upper support plate 2013, thereby ensuring that the panels can be stacked neatly on the upper support plate 2013. This ensures that the panels can be accurately moved to the corresponding production station for processing during subsequent material feeding. Specifically, the clutch mechanism 203 includes a two-way lead screw 2023 with an electric telescopic rod 2033 fixedly connected to one end away from the motor 2022. A positioning protrusion 2034 is fixedly connected to the other end of the electric telescopic rod 2033 away from the motor 2022. A positioning sleeve 2032 is provided at the other end of the positioning protrusion 2034 away from the electric telescopic rod 2033. A positioning groove 2035 is provided on the side of the positioning sleeve 2032 near the positioning protrusion 2034 for insertion and engagement with the positioning protrusion 2034. A synchronization component 2031 is connected to the side of the positioning sleeve 2032 away from the positioning protrusion 2034. The synchronization component 2031 consists of two sets of synchronous pulleys and one set of synchronous toothed belts, and is used for the transmission of the positioning sleeve 2032 and related components. It should be noted that during the upward movement of the upper support plate 2013, the electric telescopic rod 2033 is in an extended state, causing the positioning protrusion 2034 to be inserted into the positioning groove 2035 of the positioning sleeve 2032. The positioning protrusion 2034 has protrusions on both radial sides, which match the grooves on the inner wall of the positioning groove 2035. Thus, during the process of the motor 2022 driving the bidirectional lead screw 2023, other related components can be driven to run through the synchronization component 2031. Furthermore, the transfer unit 300 includes a fixing mechanism 302 disposed above the support mechanism 201 for adsorbing and fixing the panel, a guide mechanism 301 disposed on the fixing mechanism 302 for limiting the movement path of the fixing mechanism 302, and a push-pull mechanism 303 disposed on the fixing mechanism 302. The push-pull mechanism 303 and the guide mechanism 301 can be used to drive the fixing mechanism 302 to repeatedly move in an L-shaped trajectory. The fixing mechanism 302 is used to adsorb and fix the panel stored on the upper support plate 2013. Then, under the action of the push-pull mechanism 303, the fixing mechanism 302 can be driven to move. With the guide mechanism 301 limiting the fixing mechanism 302, the fixing mechanism 302 first drives the panel to move upward, and then moves axially to transport the panel to the next structure. The overall movement is in an L-shaped trajectory. After the panel is transported to the next structure, it can first move axially and then descend to prepare to adsorb and fix the next set of panels, and so on. Specifically, the guiding mechanism 301 includes a guide plate 3011 fixedly connected to the top of the bracket 100. An L-shaped guide groove 3013 is formed on the surface of the guide plate 3011. A second guide rail 3012 is fixedly connected to one side of the guide plate 3011. A sliding plate 3014 is slidably connected to the inner wall of the second guide rail 3012. An oblique guide groove 3015 is formed on the surface of the sliding plate 3014. The fixing mechanism 302 includes the sliding inner wall of the L-shaped guide groove 3013 and the oblique guide groove 3015. The limiting roller 3024 is connected to the limit roller 3024. A tripod 3021 is fixedly connected to one end of the limiting roller 3024. An I-shaped frame 3022 is fixedly connected to the end of the tripod 3021 away from the limiting roller 3024. Multiple sets of electric suction cups 3023 for adsorbing and fixing the panel are fixedly connected to the bottom of the I-shaped frame 3022. The multiple sets of electric suction cups 3023 are vacuum suction cups, which are connected to an external power supply and power control equipment through power cords to control the electric suction cups 3023 to adsorb the panel and release the panel. It should be noted that when the bidirectional lead screw 2023 rotates in the forward direction, the clutch mechanism 203 remains connected. Multiple sets of electric suction cups 3023 at the bottom of the I-beam frame 3022 are used to adhere and fix the panel on the upper support plate 2013. The guide rail 3012 on the guide plate 3011 limits and guides the sliding plate 3014. The push-pull mechanism 303 drives the sliding plate 3014 to move axially. During the movement of the sliding plate 3014, the limiting roller 3024 is obliquely guided by the sliding plate 3014. The limiting function of the groove 3015 can first drive the tripod 3021 on the limiting roller 3024 to rise when the sliding plate 3014 moves axially along the guide rail 3012. When the limiting roller 3024 contacts the inner wall of the uppermost inclined guide groove 3015, it can be guided by the L-shaped guide groove 3013, so that the tripod 3021 on the limiting roller 3024 moves axially along the L-shaped guide groove 3013, thereby transferring the panel adsorbed on the electric suction cup 3023 to the next transport structure. Specifically, the push-pull mechanism 303 includes a crank 3032 that is connected to the synchronization component 2031 via the synchronization component 2033. The end of the crank 3032 away from the synchronization component 2033 is rotatably connected to the connecting rod 3031. The end of the connecting rod 3031 away from the crank 3032 is rotatably connected to one side of the sliding plate 3014. The synchronization component 2033 also consists of two sets of synchronous toothed pulleys and one set of synchronous toothed belts for transmission between components. It should be noted that when the bidirectional lead screw 2023 rotates in the forward direction, the synchronization component 2031 drives the crank 3032 to rotate. Because the sliding plate 3014 is limited and guided by the guide rail 3012, it can be driven to repeatedly move axially through the connecting rod 3031 connected to the crank 3032. This causes multiple sets of electric suction cups 3023 to repeatedly perform L-shaped trajectory movements, repeatedly completing the transfer and transportation of the panel. Furthermore, the transport unit 400 includes a transport mechanism 401 mounted on the support 100 for transporting panels to the production station, a material-supporting mechanism 402 mounted on the transport mechanism 401, the material-supporting mechanism 402 being used to support panels transferred from the fixing mechanism 302 to the transport mechanism 401, and the material-supporting mechanism 402 also being used to place panels on the transport mechanism 401, and a push-pull mechanism 403 mounted on the material-supporting mechanism 402 for driving the material-supporting mechanism 402 to move up and down repeatedly; the material-supporting mechanism 402 can also be used to support electric... The suction cup 3023 transfers the panel above the transport mechanism 401. When the electric suction cup 3023 releases the panel and begins to reset, the material support mechanism 402 begins to descend under the action of the push-pull mechanism 403, which can stably place the panel on the transport mechanism 401. The transport mechanism 401 can accurately transport the panel to the next production processing station. When the electric suction cup 3023 picks up the next set of panels and moves towards the transport mechanism 401, the push-pull mechanism 403 starts to drive the material support mechanism 402 to move upward, preparing to lift the next set of panels. Specifically, the transport mechanism 401 includes a side frame 4011 fixedly connected to the top of the support 100. Multiple sets of conveyor rollers 4012 for transporting panels to the production station are rotatably connected to the inner wall of the side frame 4011. The material support mechanism 402 includes a U-shaped frame 4021 fixedly connected to the bottom of the side frame 4011. Multiple sets of guide rails 4023 are fixedly connected to the inner wall of the U-shaped frame 4021. A material support frame 4022 is slidably connected to the guide rails 4023. Multiple sets of fixing rods 4024 are fixedly connected to the top of the material support frame 4022, and each of the fixing rods 4024 has a material support plate 4025 fixedly connected to its top. The side frame 4011 can be equipped with transmission and power supply components for the multiple sets of conveyor rollers 4012, thus forming a complete conveying device that facilitates the accurate transfer of panels placed on the conveyor rollers 4012 to the next production station for processing. It should be noted that the electric suction cup 3023 can transport the panel and place it on the material support plate 4025 at the top of the fixed rod 4024. Then, the push-pull mechanism 403 can drive the material support frame 4022 to move down along the guide rail 4023 on the U-shaped frame 4021, and simultaneously drive the panel on the material support plate 4025 to move down, so that the panel can be slowly placed on the conveying roller 4012 for feeding and conveying. Specifically, the push-pull mechanism 403 includes a crank 3032 that is driven by a synchronization component 3033, and the crank 4032 is driven by a positioning sleeve 2032 through a synchronization component 2031. A connecting rod 4031 is rotatably connected to the end of the crank 4032 away from the synchronization component 3033 and the synchronization component 2031. The end of the connecting rod 4031 away from the crank 4032 is rotatably connected to one side of the material support frame 4022. The transmission ratio of the two sets of synchronous toothed pulleys in the synchronization component 3033 is one to one, while the transmission ratio between the two sets of synchronous toothed pulleys in the synchronization component 2031 can be set according to the thickness of the panel and the actual production and processing requirements. It should be noted that during the forward rotation of the bidirectional lead screw 2023 for feeding, the synchronization component 2 3033 can drive the crank 2 4032 to rotate. Since the material support frame 4022 is limited and guided by the guide rail 3 4023, it can drive the material support frame 4022 and the material support plate 4025 and other components to move up and down reciprocally through the connecting rod 2 4031 connected to the crank 2 4032.

[0021] The working principle of this invention is as follows: Before loading, the wooden veneer panels need to be stacked and positioned, and the support height is adjusted by the lifting mechanism 202 to ensure that the electric suction cup 3023 of the transfer unit 300 can stably adsorb the panels. At the same time, the power linkage is established by the clutch mechanism 203 to prepare for the subsequent transfer action. First, the wood veneer panels to be loaded are stacked and placed on the upper support plate 2013 of the support mechanism 201. Two sets of L-shaped positioning plates 2014 are slidably connected to the inner wall of the upper support plate 2013 to limit the two opposite corners of the panels. Since the bottom of the L-shaped positioning plate 2014 is fixedly connected to the top of the lower fixing frame 2011, its position is fixed and it is slidably engaged with the upper support plate 2013. No matter how the upper support plate 2013 is raised or lowered, it can ensure that the stacked panels are always in a centered alignment state, avoiding panel displacement that could lead to subsequent adsorption misalignment. Meanwhile, multiple sets of telescopic support rods 2012 fixed at the top of the lower fixed frame 2011 are connected to the bottom of the upper support plate 2013 to provide vertical support for the upper support plate 2013 and prevent the upper support plate 2013 from tilting due to excessive panel stacking. Then, the motor 2022 of the lifting mechanism 202 is started. The output shaft of the motor 2022 drives the bidirectional lead screw 2023 in the guide rail 2021 to rotate. Since the surface of the bidirectional lead screw 2023 has two sets of threads with opposite directions, the two sets of threaded sleeves 2024 connected by the threads on its surface will move towards each other along the inner wall of the guide rail 2021. The top rod 2025 connected to the top of the threaded sleeve 2024 rotates synchronously. The two sets of top rods 2025 form a "scissor" support structure, which lifts the upper support plate 2013 upward. The operator can adjust the number of rotations of the motor 2022 according to the panel stacking height so that the height of the top panel is matched with the adsorption height of the electric suction cup 3023 of the transfer unit 300. Usually, the top panel is 5-10mm away from the bottom of the electric suction cup 3023, which facilitates the subsequent quick contact of the suction cup with the panel. When the lifting mechanism 202 is adjusted to match the height of the upper support plate 2013, the electric telescopic rod 2033 of the clutch mechanism 203 is activated. The electric telescopic rod 2033 extends and pushes the positioning protrusion 2034 at its end to move towards the positioning sleeve 2032 until the positioning protrusion 2034 is inserted into the positioning groove 2035 opened on one side of the positioning sleeve 2032. The protrusions on both radial sides of the positioning protrusion 2034 completely match the grooves on the inner wall of the positioning groove 2035, forming a rigid transmission connection. At this time, the rotational power of the bidirectional lead screw 2023 can be transmitted to the synchronization component 2031 through the electric telescopic rod 2033, the positioning protrusion 2034, and the positioning sleeve 2032, providing a power source for the operation of the transfer unit 300 and the transport unit 400. There is no need to configure additional power for transfer and conveying, thus reducing equipment costs. After the storage unit 200 is ready, the transfer unit 300, through the cooperation of the guide mechanism 301, the fixing mechanism 302 and the push-pull mechanism 303, drives the electric suction cup 3023 to move along the L-shaped trajectory, completing the transfer action of "adsorbing the panel to vertically rising and then moving horizontally", avoiding the panel from colliding with other structures during the transfer process. The electric suction cup 3023 of the fixing mechanism 302 is activated. The electric suction cup 3023 extracts the internal air through the external vacuum system, and after forming a negative pressure, it tightly adheres to the top panel surface of the upper support plate 2013. Since the electric suction cup 3023 is fixed to the bottom of the I-shaped frame 3022, and the I-shaped frame 3022 is connected to the limiting roller 3024 through the tripod 3021, and the limiting roller 3024 is simultaneously slidably connected in the L-shaped guide groove 3013 and the oblique guide groove 3015 of the guide mechanism 301, the position of the electric suction cup 3023 is precisely limited by the guide mechanism 301, ensuring that multiple sets of electric suction cups 3023 are evenly distributed on the panel surface, avoiding single-point adsorption that could cause panel deformation. Since the clutch mechanism 203 has established a power linkage, the rotation of the bidirectional lead screw 2023 is transmitted to the synchronization component 2033 through the synchronization component 1 2031. The synchronization component 2 3033 is also composed of two sets of synchronous pulleys and a set of synchronous toothed belts, and the transmission ratio is 1:1, ensuring that the power is transmitted without speed increase or deceleration. The synchronization component 2 3033 drives the crank 1 3032 to rotate. The end of the crank 1 3032 away from the synchronization component 2 3033 is rotatably connected to the connecting rod 1 3031. The other end of the connecting rod 1 3031 is rotatably connected to one side of the sliding plate 3014. Since the sliding plate 3014 is slidably connected to the inner wall of the guide rail 2 3012 on one side of the guide plate 3011, it can only make horizontal reciprocating motion along the guide rail 2 3012. The rotational motion of the crank 1 3032 is converted into the horizontal linear motion of the sliding plate 3014 through the connecting rod 1 3031. When the sliding plate 3014 moves along the guide rail 3012 toward the storage unit 200, the oblique guide groove 3015 on the surface of the sliding plate 3014 moves synchronously. Its inner wall contacts the limiting roller 3024 and generates an oblique thrust on the limiting roller 3024. Since the limiting roller 3024 is simultaneously located in the L-shaped guide groove 3013 of the guide plate 3011, which is composed of a "vertical section plus a horizontal section", the limiting roller 3024, under the combined action of the thrust of the oblique guide groove 3015 and the limiting action of the L-shaped guide groove 3013, first moves along the vertical section of the L-shaped guide groove 3013. Sliding upwards, the tripod 3021, I-beam 3022 and electric suction cup 3023 rise vertically in sync, causing the adsorbed panel to detach from the panels stacked below. When the limiting roller 3024 slides to the top of the vertical section of the L-shaped guide groove 3013, the oblique thrust of the oblique guide groove 3015 disappears. At this time, the sliding plate 3014 continues to move horizontally, and the limiting roller 3024 slides along the horizontal section of the L-shaped guide groove 3013 toward the transport unit 400, causing the panel to move horizontally in sync until the panel moves directly above the material support mechanism 402 of the transport unit 400, completing the L-shaped trajectory transfer action. After the transfer unit 300 delivers the panel to the top of the transport unit 400, the transport unit 400 receives the panel through the material support mechanism 402, and then the push-pull mechanism 403 drives the material support mechanism 402 to slowly descend, placing the panel on the conveyor roller 4012 without damage, thus avoiding friction and wear problems caused by direct material feeding from the suction cup. While the transfer unit 300 moves the panel horizontally, the push-pull mechanism 403 of the transport unit 400 moves synchronously. The crank 4032 is connected to the positioning sleeve 2032 through the synchronization component 2031. The transmission ratio of the synchronization component 2031 can be adjusted according to the panel thickness. It is usually set to match the rising speed of the material support mechanism 402, the fixing mechanism 302 and the support mechanism 201. The crank 4032 rotates and drives the material support frame 4022 to slide upward along the guide rail 4023 on the inner wall of the U-shaped frame 4021 through the connecting rod 4031. The multiple sets of fixing rods 4024 fixed at the top of the material support frame 4022 rise synchronously. The material support plate 4025 at the top of the fixing rod 4024 rises to the bottom of the panel. When the panel moves directly above the material support mechanism 402, the top of the material support plate 4025 contacts the bottom of the panel. At this time, the vacuum system of the electric suction cup 3023 is turned off, the electric suction cup 3023 releases the panel, and the panel is completely supported by the material support plate 4025. After the panel is received, crank 4032 continues to rotate, connecting rod 4031 pulls the material support frame 4022 to slowly descend along guide rail 4023, and the material support plate 4025 drives the panel to descend synchronously. Since guide rail 4023 is a vertical linear guide rail, the material support frame 4022 descends smoothly without shaking, and the panel always remains horizontal. When the material support plate 4025 lowers the panel to contact the surface of the conveyor roller 4012 of the transport mechanism 401, the material support frame 4022 continues to descend, the material support plate 4025 detaches from the bottom of the panel, and the panel is completely placed on the conveyor roller 4012. The multiple sets of conveyor rollers 4012 rotatably connected to the inner wall of the side frame 4011 always keep rotating. After the panel is placed, it immediately moves synchronously with the conveyor roller 4012 and is transported to the next production station. Since the panel is slowly lowered from the material support plate 4025 to the conveyor roller 4012, and the conveyor roller 4012 has already made synchronous contact with the panel when it is lowered, there is no relative sliding friction, which effectively avoids problems such as panel wear and deformation caused by delayed loosening of the suction cup during material feeding. After a single panel is conveyed, each unit structure is reset in sequence, ready to feed the next panel, thus realizing continuous automated production. After the panel is received by the material support mechanism 402, the crank 3032 of the push-pull mechanism 303 rotates in the opposite direction, and pulls the sliding plate 3014 along the guide rail 3012 away from the transport unit 400 through the connecting rod 3031. The inclined guide groove 3015 of the sliding plate 3014 drives the limiting roller 3024 to slide in the opposite direction along the horizontal section of the L-shaped guide groove 3013, and after returning to the top of the vertical section, slide down along the vertical section until the electric suction cup 3023 returns to the initial suction position, ready to suction the next panel. After each panel is transferred, the stacking height of the panels on the upper support plate 2013 decreases. At this time, the motor 2022 continues to drive the bidirectional lead screw 2023 to rotate, causing the two sets of threaded sleeves 2024 to continue to move towards each other. The top rod 2025 pushes the upper support plate 2013 upward again, and the lifting height is equal to the thickness of a single panel, ensuring that the next panel is still at the adsorption height that is compatible with the electric suction cup 3023, without the need for manual intervention. After a batch of panels has been transferred, there are no panels left on the upper support plate 2013. At this time, the electric telescopic rod 2033 is activated to retract, which drives the positioning protrusion 2034 to disengage from the positioning groove 2035 of the positioning sleeve 2032. The clutch mechanism 203 disconnects the power linkage, the motor 2022 rotates in the opposite direction, the bidirectional lead screw 2023 drives the threaded sleeve 2024 to move in the opposite direction, the top rod 2025 retracts, and the upper support plate 2013 descends along the telescopic support rod 2012 to the initial low position. The operator can then stack the next batch of panels on the upper support plate 2013. After placement, restart the electric telescopic rod 2033 to establish power linkage and repeat the above feeding process to achieve rapid switching between batches.
