Description

Technical Field

[0001] This disclosure relates to the field of panel processing technology, specifically to a panel feeding mechanism. Background Technology

[0002] In today's industrial production, panel processing and manufacturing is a crucial link, with panel loading mechanisms playing an indispensable role. However, in the practical application of related technologies, panel loading mechanisms have revealed some problems that urgently need to be solved. Specifically, the dimensions of its core component, the loading platform, are usually fixed. This fixed-size design makes the loading platform extremely limited when facing the loading requirements of panels of different specifications.

[0003] When faced with the task of processing large-size panels, existing loading platforms, due to insufficient support area, pose numerous risks during panel transportation. During transport, panels are highly susceptible to tilting or even impacts. Once tilted or impacted, the surface integrity and internal structure of the panel may be damaged, which undoubtedly has a serious impact on the final product quality, directly leading to a decrease in product yield, increased production costs, and negatively affecting the company's economic benefits and market competitiveness.

[0004] To address the issue of feeding panels of different sizes, a common approach is to replace the feeding mechanism with one adapted to the different dimensions. However, this solution introduces new challenges. Replacing the feeding mechanism not only significantly increases equipment costs, requiring companies to invest more capital in equipment upfront, but also markedly increases operational complexity. This increased complexity demands higher skill levels from operators and increases the risk of operational errors, further impacting production efficiency and product quality. Summary of the Invention

[0005] The main objective of this disclosure is to provide a panel feeding mechanism to solve the problems of poor adaptability and insufficient support for large-size panels that are easily damaged due to fixed dimensions in related technologies.

[0006] This disclosure achieves the technical effects of expanding the size of the feeding platform and improving the feeding adaptability through the cooperation of the main feeding unit and the auxiliary feeding unit.

[0007] To achieve the above objectives, this disclosure provides a panel feeding mechanism, including a main feeding unit and at least one auxiliary feeding unit. The main feeding unit has a feeding platform that can directly or indirectly drive the panel feeding. At least one auxiliary feeding unit is disposed around the main feeding unit, and the auxiliary feeding unit can cooperate with the main feeding unit to expand the panel feeding size.

[0008] The auxiliary feeding unit includes a lifting structure and a support unit. The lifting structure is located below the support unit and can lift the support unit to a position flush with the feeding platform to expand the size of the feeding platform.

[0009] In the above structure, the cooperation between the main feeding unit and the auxiliary feeding unit achieves the technical effects of expanding the size of the feeding platform and improving its adaptability. Specifically, the lifting structure of the auxiliary feeding unit raises and lowers the support unit to be flush with the feeding platform, which, in conjunction with the main feeding unit, expands the feeding size of the panels to meet the feeding needs of panels of different specifications. Furthermore, the auxiliary feeding unit allows for flexible adjustment of the bearing area of ​​the feeding platform, enhancing its adaptability to large-size or special-specification panels and improving the versatility of the mechanism.

[0010] In some examples, the main feeding unit includes a supporting body and a plurality of main support frames disposed on the supporting body. Each main support frame is provided with at least one first guide wheel, and the first guide wheel is rotatably connected to the main support frame through a first rotating shaft.

[0011] Multiple first guide wheels together form a feeding platform. All first guide wheels are at the same height and roll in the same direction. The rolling direction of the first guide wheels is the same as or opposite to the feeding direction of the panel.

[0012] When the first guide wheel rolls in the same direction as the panel's feeding direction, it assists in conveying the panel, allowing it to move more smoothly along the feeding direction. When the first guide wheel rolls in the opposite direction to the panel's feeding direction, it can control the panel's movement speed to some extent, preventing the panel from slipping due to excessive speed. Simultaneously, the main support frames are securely connected via connectors to enhance the overall structural strength of the main feeding unit, ensuring that it does not shake or deform during panel feeding and guaranteeing stable feeding operations.

[0013] In some examples, the auxiliary feeding unit also includes an auxiliary support frame connected to the lifting structure. The auxiliary support frame can change its height as the lifting structure rises and falls, and the support part is installed on the auxiliary support frame. A position sensor is provided on the auxiliary support frame.

[0014] In the above structure, the position sensor can monitor the height of the auxiliary support frame in real time, ensuring that the support part is accurately raised and lowered to a position flush with the main loading platform through the lifting structure, avoiding panel loading jamming or tilting due to height deviation.

[0015] The auxiliary support frame and the lifting structure can be rigidly connected to provide a stable installation base for the support. When bearing the weight of the panel, it can distribute stress, prevent the support from shaking or deforming, and improve the structural stability of the extension platform.

[0016] When the height of the main loading platform changes due to working conditions (such as differences in panel thickness), the position sensor can provide real-time feedback on the height error. The height of the auxiliary support frame is dynamically adjusted through the lifting structure to ensure that it is always horizontally aligned with the main platform.

[0017] In some examples, the support includes an auxiliary mounting plate, a second rotating shaft mounted on the auxiliary mounting plate, and a second guide wheel rotatably connected to the second rotating shaft. The main feeding unit includes multiple first guide wheels, which together form a feeding platform.

[0018] Driven by the lifting structure, the second guide wheel can be indirectly raised to a position level with the first guide wheel, thereby expanding the load-bearing area of ​​the loading platform.

[0019] In the above structure, the second guide wheel, driven by the lifting structure, is flush with the first guide wheel. Together, they form an expanded loading platform, effectively increasing the support range for the panel and meeting the load-bearing requirements of large-sized panels. The second guide wheel is rotatably connected via a second rotating shaft, forming a rolling support surface with the first guide wheel. During loading, the panel can be smoothly conveyed through the rolling of the guide wheels, reducing resistance and panel damage caused by sliding friction. The support part, through an auxiliary mounting plate, can form a modular structure with the second rotating shaft, matching the structure of the first guide wheel in the main loading unit. This ensures that the expanded loading platform has a consistent height and uniform load-bearing capacity, preventing the panel from bending or bumping due to uneven support.

[0020] In some examples, the support includes at least two rows of spaced-apart second guide wheels. The support in the above structure can contain two rows of spaced-apart second guide wheels. The main purpose of this design is to significantly improve overall stability and support effect, ensuring smoother and more reliable operation. Of course, depending on the specific application requirements, it is also possible to flexibly choose to include only one row of second guide wheels to simplify the structure and adapt to specific usage environments.

[0021] Alternatively, the outer peripheries of the first and second guide wheels can be made of flexible materials. In the above structures, the outer peripheries of the first and second guide wheels specifically utilize flexible structural materials. The initial design intention of this flexible structure is to effectively reduce friction and damage to the panel during the feeding process, thereby better protecting the integrity of the panel and extending its service life. This meticulous design consideration not only improves the performance of the equipment but also reflects thoughtful attention to the details of use.

[0022] In some examples, the lifting structure is at least one of the following: a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, a combination of a motor and a transmission mechanism, or a threaded lifting rod.

[0023] When a pneumatic cylinder is used as the lifting structure, it features rapid action and sensitive response, enabling it to complete the lifting and lowering of the support unit in a short time, making it suitable for scenarios requiring high material loading efficiency. Furthermore, the pneumatic cylinder has a relatively simple structure, is easy to maintain, and has a relatively low cost. However, the output force of a pneumatic cylinder may be affected by air pressure fluctuations, resulting in slightly weaker stability.

[0024] Hydraulic cylinders, as lifting mechanisms, can provide significant output force, easily supporting heavy panels and are suitable for loading large and heavy panels. Their smooth operation ensures the stability of the support structure during lifting, reducing the adverse effects of vibration on the loading process. However, hydraulic cylinders are susceptible to oil leakage, requiring regular inspection and maintenance, and their response time is relatively slow.

[0025] Electric cylinders combine the precision of electrical control with the stability of mechanical structures. They enable precise position control and speed adjustment, accurately raising and lowering the support unit to designated positions according to different feeding requirements. Electric cylinders offer flexible and diverse control methods, allowing for automated operation through programming, thus improving the intelligence level of the feeding process. However, electric cylinders are relatively expensive and have strict requirements for the operating environment, such as avoiding use in humid or dusty environments.

[0026] The combination of a motor and a transmission mechanism is also a common type of lifting structure. The motor provides power, which is transmitted to the support unit through a transmission mechanism (such as gear drive or chain drive) to achieve lifting. This structure can be designed with different transmission ratios according to actual needs, thereby adjusting the lifting speed and output force of the support unit. Its advantage is its flexible structure, allowing for customized design according to different application scenarios. However, the transmission mechanism may generate some noise and wear during operation, requiring regular lubrication and maintenance.

[0027] The threaded lifting rod utilizes the rotational motion of the thread to raise and lower the support section. It features a simple structure and good self-locking properties, maintaining the stability of the support section when stationary and preventing descent due to gravity. The threaded lifting rod offers high transmission precision, enabling relatively accurate lifting control. However, its lifting speed is relatively slow, making it suitable for material loading scenarios where high lifting speed is not required but high positional accuracy is. In practical applications, the most suitable lifting structure can be selected based on factors such as specific panel specifications, loading frequency, and cost budget to ensure efficient and stable operation of the panel loading mechanism.

[0028] In some examples, two auxiliary feeding units are provided, one on each side of the main feeding unit. Alternatively, the two auxiliary feeding units are located on the same side of the main feeding unit. Or, the two auxiliary feeding units are located on adjacent sides of the main feeding unit.

[0029] Alternatively, three auxiliary feeding units may be provided, each located on a different side of the main feeding unit. Alternatively, at least two of the three auxiliary feeding units may be located on the same side of the main feeding unit.

[0030] Alternatively, four auxiliary feeding units may be provided, with each of the four auxiliary feeding units located on a different side of the main feeding unit. Alternatively, at least two of the four auxiliary feeding units may be located on the same side of the main feeding unit.

[0031] When two auxiliary feeding units are set up and located on opposite sides of the main feeding unit, this layout forms a symmetrical support structure, effectively balancing the force on the panel during the feeding process. This is especially suitable for feeding long or large panels, reducing the risk of tilting due to unilateral force. If the two auxiliary feeding units are set on the same side of the main feeding unit, it is more suitable for handling panels with a heavier or irregular shape on one side, improving stability through concentrated support. However, attention should be paid to the potential for uneven force distribution on the opposite side. When the two auxiliary feeding units are set on adjacent sides of the main feeding unit, an L-shaped support structure is formed. This is suitable for scenarios where panels need to be supported from two directions simultaneously, such as at corners or in special process flows.

[0032] When three auxiliary feeding units are set up and located on different sides of the main feeding unit, a comprehensive support system can be formed. This is especially suitable for feeding scenarios with irregularly shaped panels or requiring multi-angle positioning, ensuring the panel remains stable in any position through three-point support. If at least two of the three auxiliary feeding units are located on the same side of the main feeding unit, double support can be provided in key stress areas, while retaining auxiliary support on the other side. This is suitable for scenarios where the panel weight distribution is uneven or requires local reinforcement.

[0033] When four auxiliary feeding units are set up and located on different sides of the main feeding unit, a complete four-sided support structure can be constructed, providing the most stable support environment for the panel. This is especially suitable for feeding ultra-large and ultra-heavy panels, maximizing pressure distribution and reducing the risk of deformation. If at least two of the four auxiliary feeding units are located on the same side of the main feeding unit, redundant support can be formed in critical areas. For example, when the panel's center of gravity shifts, the two units can work together to prevent tipping, while retaining auxiliary support on other sides to cope with dynamic changes. In practical applications, the number and layout of auxiliary feeding units need to be comprehensively determined based on the panel size, weight distribution, process flow, and site conditions. Flexible combinations can be achieved through modular design, meeting both standardized production needs and customized application scenarios.

[0034] In some examples, the main feeding unit also includes a flexible lifting unit, which is interspersed with other components and rises and falls independently. The flexible lifting unit includes a lifting bracket and multiple flexible lifting rods mounted on the lifting bracket.

[0035] The flexible lifting unit design further enhances the adaptability and stability during panel loading. The lifting bracket, as the basic structure of the flexible lifting unit, is made of high-strength materials to ensure stability when bearing the weight of the panel. Multiple flexible lifting rods are evenly distributed on the lifting bracket, each with independent lifting capabilities, allowing for precise adjustment based on the actual shape and weight distribution of the panel.

[0036] In some examples, the flexible lifting rod includes a rod body and flexible caps at the ends of the rod body. Multiple flexible caps are at the same height and form a flexible lifting surface, which can lift or lower the panel.

[0037] The flexible lifting head is made of carefully selected materials, typically featuring high elasticity and good abrasion resistance, such as silicone or specialty engineering plastics. This design ensures sufficient lifting force upon contact with the panel while preventing scratches or indentations on the panel surface. The flush design of the flexible lifting surface allows the panel to remain level during lifting, preventing slippage or damage due to tilting.

[0038] In some examples, the main feeding unit also includes an air flotation lifting unit, which is interspersed with other components and lifts and lowers independently. The air flotation lifting unit includes a lifting assembly, an air flotation support connected to the lifting assembly, and multiple air flotation nozzles mounted on the air flotation support.

[0039] The air flotation lifting unit can use negative pressure to adsorb the panel during feeding or use air jet to suspend the panel during feeding.

[0040] The air-bearing lifting unit offers a more flexible and efficient solution for panel loading. As the core drive component of the air-bearing lifting unit, the lifting assembly typically employs a high-precision servo motor or stepper motor to ensure the smoothness and accuracy of the lifting process. Through its connection with the air-bearing support, the lifting assembly can move the entire air-bearing support up and down, thereby achieving precise positioning of the panel.

[0041] The air flotation support, serving as the load-bearing structure for the air flotation nozzles, is designed with full consideration for the uniformity and stability of airflow distribution. Multiple air flotation nozzles are evenly distributed on the air flotation support, and each nozzle can independently control the direction and intensity of the airflow. This design allows the air flotation lifting unit to perform personalized airflow adjustments based on the size, shape, and weight distribution of different panels, achieving better material feeding results.

[0050] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] Reference Figures 1 to 6This disclosure provides a panel feeding mechanism, including a main feeding unit 100 and at least one auxiliary feeding unit 200. The main feeding unit 100 has a feeding platform that can directly or indirectly feed a panel 300. At least one auxiliary feeding unit 200 is disposed around the main feeding unit 100, and the auxiliary feeding unit 200 can cooperate with the main feeding unit 100 to expand the feeding size of the panel 300.

[0052] The auxiliary feeding unit 200 includes a lifting structure 220 and a support part 230. The lifting structure 220 is located below the support part 230. The lifting structure 220 can drive the support part 230 to rise and fall to a position flush with the feeding platform, so as to expand the size of the feeding platform.

[0053] In the above structure, the cooperation between the main feeding unit 100 and the auxiliary feeding unit 200 achieves the technical effects of expanding the size of the feeding platform and improving the adaptability of the feeding process. Specifically, the lifting structure 220 of the auxiliary feeding unit 200 drives the support part 230 to rise and fall to be flush with the feeding platform, which can cooperate with the main feeding unit 100 to expand the feeding size of the panel 300 and meet the feeding needs of panels 300 of different specifications. Furthermore, the auxiliary feeding unit 200 allows for flexible adjustment of the bearing area of ​​the feeding platform, enhancing its adaptability to large-size or special-specification panels 300 and improving the versatility of the mechanism.

[0054] In practical applications, the feeding platform of the main feeding unit 100 can be designed in various forms to adapt to panels 300 of different shapes and sizes. For example, the feeding platform can be set as a rectangle, a circle or other irregular structure, as long as it can meet the functional requirements of feeding the panels 300.

[0055] The lifting structure 220 in the auxiliary feeding unit 200 can be driven by an electric push rod, hydraulic cylinder, or pneumatic cylinder to achieve stable lifting of the support part 230. The support part 230 can be made of high-strength metal or alloy material to ensure that it will not deform or be damaged when bearing the weight of the panel 300.

[0056] Furthermore, the number and position of the auxiliary feeding units 200 can be adjusted according to actual needs. For example, when it is necessary to increase the lateral dimension of the feeding platform, an auxiliary feeding unit 200 can be set on each side of the main feeding unit 100; when it is necessary to increase the longitudinal dimension of the feeding platform, auxiliary feeding units 200 can be set at both the front and rear ends of the main feeding unit 100. By rationally arranging the auxiliary feeding units 200, the flexibility and applicability of the panel feeding mechanism can be further improved.

[0057] Reference Figures 10 to 12The panel loading mechanism works in conjunction with the transfer mechanism 400 to transfer the panel 300. The transfer mechanism 400 can pick up or feed the panel 300 as needed. The transfer mechanism 400 typically consists of a robotic arm, a transmission device, and a precise positioning system. The robotic arm can be a single-degree-of-freedom structure similar to a forklift's pick-and-place mechanism, using a similar principle to transfer the panel 300. Alternatively, the robotic arm can have multiple degrees of freedom, allowing it to extend, rotate, and grasp flexibly to adapt to different positions and postures of the panel 300 during pick-up and place operations. The transmission device provides power support for the robotic arm's movement, ensuring smooth and precise operation. The precise positioning system utilizes advanced sensor technology to quickly and accurately identify the position information of the panel 300 and feed this information back to the control system, enabling the robotic arm to precisely reach the designated position for pick-up or feed operations. Through the close cooperation between the panel loading mechanism and the transfer mechanism 400, the automation level and production efficiency of the entire production process can be greatly improved.

[0058] Reference Figures 1 to 6 In some examples, the main feeding unit 100 includes a supporting main body 110 and a plurality of main support frames 120 disposed on the supporting main body 110. Each main support frame 120 is provided with at least one first guide wheel 130, and the first guide wheel 130 is rotatably connected to the main support frame 120 through a first rotating shaft 131.

[0059] Multiple first guide wheels 130 together form a feeding platform. All first guide wheels 130 are at the same height and roll in the same direction. The rolling direction of the first guide wheels 130 is the same as or opposite to the feeding direction of the panel 300.

[0060] When the rolling direction of the first guide wheel 130 is the same as the feeding direction of the panel 300, it can assist in conveying the panel 300, allowing the panel 300 to move more smoothly along the feeding direction. When the rolling direction of the first guide wheel 130 is opposite to the feeding direction of the panel 300, it can control the moving speed of the panel 300 to a certain extent, preventing the panel 300 from moving too fast and slipping. At the same time, the main support frames 120 can be stably connected through connectors to enhance the overall structural strength of the main feeding unit 100, ensuring that the main feeding unit 100 will not shake or deform during the feeding process of the panel 300, thus ensuring the stable operation of the feeding work.

[0061] In actual operation, when panel 300 is placed on the loading platform, the first guide wheel 130 can smoothly drive panel 300 to move, ensuring the continuity and stability of the loading process. Furthermore, the rolling direction of the first guide wheel 130 can be adjusted according to actual needs to adapt to loading operations in different directions.

[0062] The main support frame 120 serves as the mounting base for the first guide wheel 130, and its structural design and material selection are crucial. The main support frame 120 can be made of high-strength steel or aluminum alloy to ensure sufficient load-bearing capacity and stability. Furthermore, the shape and dimensions of the main support frame 120 can be customized according to the specific form of the loading platform to ensure a perfect match.

[0063] To further improve the stability and load-bearing capacity of the loading platform, reinforcing ribs or connecting plates can be installed between the main support frames 120 to enhance the rigidity and strength of the overall structure. In addition, adjustable feet or a level can be installed at the bottom of the main support frame 120 to allow for leveling of the loading platform during installation, ensuring a smooth loading process.

[0064] In addition to the aforementioned lifting structure 220 and support 230, other auxiliary devices can be added to the auxiliary feeding unit 200 according to actual needs. For example, a positioning device or sensor can be installed on the support 230 to achieve precise positioning and detection of the panel 300. When the panel 300 is placed on the support 230, the positioning device can quickly determine the position and orientation of the panel 300 and feed the information back to the control unit; the sensor can monitor the weight, size and other parameters of the panel 300 in real time, providing data support for optimizing the feeding process.

[0065] Meanwhile, to ensure coordinated operation between the auxiliary feeding unit 200 and the main feeding unit 100, the control unit must possess a high level of intelligence and automation. The control unit can automatically adjust the lifting height and position of the auxiliary feeding unit 200 according to preset programs and real-time monitored data to ensure it remains flush with the feeding platform of the main feeding unit 100. Furthermore, the control unit can perform real-time monitoring and fault diagnosis of the feeding process. Once an abnormality is detected, it will immediately issue an alarm and take corresponding protective measures to ensure the safety and reliability of the feeding process.

[0066] The aforementioned main support frame 120 can be a frame structure to provide stable support for the first guide wheel 130, ensuring that the first guide wheel 130 will not wobble or deviate during the feeding process of the panel 300. The surface of the first guide wheel 130 is specially treated to have a low coefficient of friction, which can both ensure that the panel 300 moves smoothly on the feeding platform and reduce damage to the panel 300 caused by friction.

[0067] Reference Figure 5 and Figure 6In some examples, the auxiliary feeding unit 200 further includes an auxiliary support frame 210, which is connected to the lifting structure 220. The auxiliary support frame 210 can change its height as the lifting structure 220 rises and falls. The support part 230 is installed on the auxiliary support frame 210. A position sensor 240 is provided on the auxiliary support frame 210.

[0068] In the above structure, the position sensor 240 can monitor the height position of the auxiliary support frame 210 in real time, ensuring that the support part 230 is accurately raised and lowered to a position flush with the main loading platform through the lifting structure 220, so as to avoid the panel 300 from getting stuck or tilted due to height deviation.

[0069] The auxiliary support frame 210 and the lifting structure 220 can be rigidly connected to provide a stable installation base for the support part 230. When bearing the weight of the panel 300, it can distribute stress, prevent the support part 230 from shaking or deforming, and improve the structural stability of the extension platform.

[0070] When the height of the main loading platform changes due to working conditions (such as differences in the thickness of panel 300), the position sensor 240 can provide real-time feedback on the height error and dynamically adjust the height of the auxiliary support frame 210 through the lifting structure 220 to ensure that it is always horizontally aligned with the main platform.

[0071] The position sensor 240 in the above structure can monitor the height position information of the auxiliary support frame 210 in real time and transmit this information accurately to the control unit. After receiving the position information, the control unit will combine the working status of the main feeding unit 100 and preset parameters to precisely control the lifting and lowering of the auxiliary support frame 210.

[0072] When the height of the loading platform of the main loading unit 100 changes, the control unit can quickly direct the lifting structure 220 to drive the auxiliary support frame 210 to adjust the height accordingly based on the data fed back by the position sensor 240. This ensures that the support part 230 is always at a suitable height that matches the loading platform of the main loading unit 100, thereby further ensuring the stability and accuracy of the panel 300 during the loading process and improving the working efficiency and reliability of the entire panel loading mechanism.

[0073] In practical applications, the position sensor 240 can be of various types, such as photoelectric sensors, magnetic sensors, or laser sensors. The specific selection needs to be based on a comprehensive consideration of factors such as the material and structure of the auxiliary support frame 210 and the operating environment. For example, in complex environments or where there are many interference factors, laser sensors, with their high precision and strong anti-interference capabilities, can more accurately monitor the position changes of the auxiliary support frame 210.

[0074] Furthermore, the design of the auxiliary support frame 210 must fully consider its load-bearing capacity and stability. The auxiliary support frame 210 can be made of the same material as the main support frame 120, such as high-strength steel or aluminum alloy, to ensure that it will not deform or be damaged when bearing the weight of the support section 230 and the panel 300. At the same time, the structural design of the auxiliary support frame 210 should be simple and reasonable, facilitating connection and installation with the lifting structure 220, and reducing manufacturing and maintenance costs.

[0075] To further enhance the flexibility and applicability of the auxiliary feeding unit 200, the auxiliary support frame 210 can also be designed as an adjustable structure. For example, multiple mounting holes or adjustment slots can be provided on the auxiliary support frame 210 to adjust the mounting position and angle of the support part 230 according to actual needs. In this way, when it is necessary to handle panels 300 of different shapes and sizes, simply adjusting the position and angle of the support part 230 can achieve a perfect fit with the main feeding unit 100, meeting diverse feeding requirements.

[0076] Reference Figure 5 and Figure 6 In some examples, the support 230 includes an auxiliary mounting plate 231, a second rotating shaft 232 mounted on the auxiliary mounting plate 231, and a second guide wheel 233 rotatably connected to the second rotating shaft 232. The main loading unit 100 includes multiple first guide wheels 130, which together form a loading platform. Driven by the lifting structure 220, the second guide wheel 233 can be indirectly raised to a position flush with the first guide wheels 130, thereby expanding the load-bearing area of ​​the loading platform.

[0077] In the above structure, the second guide wheel 233, driven by the lifting structure 220, is flush with the first guide wheel 130. Together, they form an expanded loading platform, effectively increasing the support range for the panel 300 and meeting the load-bearing requirements of the large-size panel 300. The second guide wheel 233 is rotatably connected to the second rotating shaft 232, forming a rolling support surface with the first guide wheel 130. During the loading process, the panel 300 can be smoothly conveyed through the rolling of the guide wheel, reducing resistance caused by sliding friction and damage to the panel 300. The support part 230 can form a modular structure with the second rotating shaft 232 through the auxiliary mounting plate 231, matching the structure of the first guide wheel 130 of the main loading unit 100, ensuring that the expanded loading platform has a consistent height and uniform load, and preventing the panel 300 from bending or bumping due to uneven support.

[0078] In practical applications, this setup offers numerous advantages. When handling larger panels 300, the lifting structure 220 raises the second guide wheel 233 to be flush with the first guide wheel 130. This effectively expands the load-bearing area of ​​the loading platform, which was originally composed of multiple first guide wheels 130, allowing for more stable support and transport of the panel 300. This prevents the panel 300 from tilting or slipping due to insufficient load-bearing area, significantly improving loading stability and safety. Furthermore, the cooperation between the second guide wheel 233 and the first guide wheel 130 is highly flexible. When an increased load-bearing area is not required, the second guide wheel 233 can be positioned at a lower level, without interfering with normal loading operations. Simultaneously, this adjustable support 230 design allows the panel loading mechanism to adapt to the loading needs of panels 300 of different specifications, eliminating the need for custom-designed loading mechanisms for each panel 300 specification. This reduces production and operating costs and enhances the equipment's versatility and practicality.

[0079] The second guide wheel 233 can maintain the same material and structure as the first guide wheel 130, both being made of wear-resistant, low-friction materials to reduce wear and resistance on the panel 300 during the feeding process. Simultaneously, the rolling direction of the second guide wheel 233 can be the same as or opposite to that of the first guide wheel 130, allowing for flexible adjustment based on actual feeding requirements. When rapid conveying of the panel 300 is needed, both roll in the same direction, creating continuous conveying force; when controlling the movement speed of the panel 300 is required, they roll in opposite directions, achieving speed adjustment through friction.

[0080] In actual operation, when the lifting structure 220 of the auxiliary feeding unit 200 drives the support part 230 to rise, the second guide wheel 233 gradually approaches and eventually aligns with the first guide wheel 130. At this time, the panel 300 can be placed on both the first guide wheel 130 and the second guide wheel 233, and is supported and transported by both. This design not only expands the load-bearing area of ​​the feeding platform, but also improves the stability and reliability of the feeding process. Even when faced with large-sized or specially shaped panels 300, a smooth and efficient feeding operation can be achieved by adjusting the position and number of the auxiliary feeding units 200.

[0081] Furthermore, to ensure precise alignment between the second guide wheel 233 and the first guide wheel 130, a guiding device or calibration mechanism can be installed on the auxiliary support frame 210. These devices or mechanisms can fine-tune the position of the second guide wheel 233 during lifting, ensuring that the gap and height difference between it and the first guide wheel 130 are controlled within allowable limits. This ensures smooth movement and precise positioning of the panel 300 during the loading process, even under different operating conditions.

[0082] Meanwhile, a shock-absorbing device or buffer mechanism can also be installed between the support 230 and the auxiliary support frame 210. These devices or mechanisms can effectively absorb and disperse vibration energy, reducing damage to the feeding mechanism and the panel 300. For example, a rubber pad or spring shock absorber can be installed between the auxiliary mounting plate 231 and the auxiliary support frame 210 to absorb vibration energy through its elastic deformation, thereby improving the stability and durability of the feeding mechanism.

[0083] Reference Figure 5 and Figure 6 In some examples, the support portion 230 includes at least two rows of spaced-apart second guide wheels 233. The support portion 230 in the above structure may include two rows of spaced-apart second guide wheels 233. The main purpose of this design is to significantly improve overall stability and support effect, ensuring smoother and more reliable operation. Of course, depending on the actual application requirements, it is also possible to flexibly choose to provide only one row of second guide wheels 233 to simplify the structure and adapt to specific usage environments.

[0084] Alternatively, the outer periphery of the first guide wheel 130 and the second guide wheel 233 may be a flexible structure. In the above structure, the outer periphery of the first guide wheel 130 and the second guide wheel 233 specifically utilizes a flexible structural material. The initial design intention of this flexible structure is to effectively reduce the friction and damage that may be caused to the panel 300 during the feeding process, thereby better protecting the integrity of the panel 300 and extending its service life. Through this meticulous design consideration, not only is the performance of the equipment improved, but it also reflects thoughtful care for the details of use.

[0085] In other examples, the flexible structure can be made of rubber, which not only has a certain degree of flexibility to effectively reduce the impact force when in contact with the panel 300, but also provides appropriate friction to prevent the panel 300 from slipping during the feeding process. Alternatively, the flexible structure can also be a flexible sleeve wrapped around the outer periphery of the guide wheel. This flexible sleeve is fixed to the guide wheel by a specific connection method, such as snap-fit ​​or adhesive, making it easy to replace after wear. In addition, to further improve the adaptability of the feeding mechanism to panels 300 of different sizes, an adjustable spacing device can be provided in the support 230. The spacing between the two rows of second guide wheels 233 can be adjusted manually or electrically to meet the feeding requirements of panels 300 of different specifications.

[0086] Reference Figures 7 to 9In other examples, at least one of the first and second guide wheels is equipped with a fine-tuning mechanism to finely adjust the height of each guide wheel. By incorporating a fine-tuning mechanism on at least one of the first and second guide wheels, operators can precisely adjust the height of each guide wheel according to actual needs. This design greatly enhances the flexibility and adaptability of the loading platform, especially when handling panels with uneven surfaces or slight height differences, ensuring that each guide wheel maintains a tight and uniform contact with the panel. This not only effectively avoids slippage or jamming caused by poor contact between the panel and the guide wheels but also further improves the stability and reliability of the loading process, providing a strong guarantee for high-quality panel processing. Simultaneously, the addition of the fine-tuning mechanism also enables the entire panel loading mechanism to exhibit superior versatility and compatibility when handling panels of different specifications and materials.

[0087] The fine-tuning mechanism can be a dual-axis mechanism 500, a gear and rack mechanism, a lead screw and nut mechanism, or other mechanisms that can perform local fine-tuning.

[0088] Taking the dual-axis mechanism 500 as an example, the dual-axis mechanism 500 includes a rotating shaft 510 and an adjusting shaft. A guide wheel is rotatably connected to the rotating shaft 510, and the adjusting shaft can adjust the position of the rotating shaft 510. The specific configuration can be set according to needs. In practical applications, the dual-axis mechanism 500 can drive the rotating shaft 510 to make slight vertical displacements by rotating the adjusting shaft, thereby achieving precise control of the guide wheel height. This structure not only offers flexible adjustment range but is also easy to operate, quickly adapting to the feeding requirements of panels of different thicknesses.

[0089] Furthermore, referring to Figures 7 to 9 The rotating shaft 510 and the adjusting shaft can be set as one unit. The rotating shaft 510 is set off-center relative to the adjusting shaft. Thus, the height of the rotating shaft 510 can be adjusted by rotating the adjusting shaft, thereby achieving the height adjustment of the guide wheel.

[0090] The rack and pinion mechanism utilizes the meshing of gears and racks to convert rotational motion into linear motion, and precisely controls the height of the guide wheel by adjusting the rotation angle of the gears. This mechanism features smooth transmission and high precision, making it suitable for scenarios with strict requirements on the height of the guide wheel.

[0091] The lead screw and nut mechanism uses the rotation of the lead screw to drive the nut to move linearly, thereby adjusting the height of the guide wheel. This mechanism has a compact structure and good self-locking performance, and can maintain the stability of the guide wheel's position after adjustment, preventing height changes due to vibration or external forces.

[0092] In addition, the fine-tuning mechanism can be equipped with auxiliary devices such as a dial or digital display screen, so that operators can read and adjust the height value of the guide wheel more intuitively and accurately, further improving the ease of operation and adjustment accuracy of the feeding mechanism.

[0093] In some examples, the lifting structure 220 is at least one of a combination of a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, a motor and a transmission mechanism, or a threaded lifting rod.

[0094] When a pneumatic cylinder is used as the lifting structure 220, it features rapid action and sensitive response, enabling it to complete the lifting action of the support 230 in a short time, making it suitable for scenarios with high requirements for material feeding efficiency. Furthermore, the pneumatic cylinder has a relatively simple structure, is easy to maintain, and has a relatively low cost. However, the output force of the pneumatic cylinder may be affected by air pressure fluctuations, resulting in slightly weaker stability.

[0095] The hydraulic cylinder, serving as the lifting structure 220, provides significant output force, easily supporting heavy panels 300 and is suitable for loading large and heavy panels 300. Its smooth operation ensures the stability of the support 230 during lifting, reducing the adverse effects of vibration on the loading process. However, hydraulic cylinders are susceptible to oil leakage, requiring regular inspection and maintenance, and their response time is relatively slow.

[0096] Electric cylinders combine the precision of electrical control with the stability of mechanical structures. They enable precise position control and speed adjustment, accurately raising and lowering the support unit 230 to designated positions according to different feeding requirements. Electric cylinders offer flexible and diverse control methods, allowing for automated operation through programming, thus improving the intelligence level of the feeding process. However, electric cylinders are relatively expensive and have strict requirements for the operating environment, such as avoiding use in humid or dusty environments.

[0097] The combination of a motor and a transmission mechanism is also a common type of lifting structure 220. The motor provides power, which is transmitted to the support unit 230 via a transmission mechanism (such as gear drive or chain drive) to achieve lifting. This structure can be designed with different transmission ratios according to actual needs, thereby adjusting the lifting speed and output force of the support unit 230. Its advantage is its flexible structure, allowing for customized design according to different application scenarios. However, the transmission mechanism may generate some noise and wear during operation, requiring regular lubrication and maintenance.

[0098] The threaded lifting rod utilizes the rotational motion of the thread to raise and lower the support section 230. It features a simple structure and good self-locking properties, maintaining the stable position of the support section 230 when it stops moving, preventing it from descending due to gravity. The threaded lifting rod has high transmission precision, enabling relatively accurate lifting control. However, its lifting speed is relatively slow, making it suitable for material loading scenarios where high lifting speed is not required but high positional accuracy is. In practical applications, the most suitable lifting structure 220 can be selected based on factors such as the specific panel 300 specifications, loading frequency, and cost budget to ensure efficient and stable operation of the panel loading mechanism.

[0099] In some examples, two auxiliary feeding units 200 are provided, with the two auxiliary feeding units 200 respectively located on opposite sides of the main feeding unit 100. Alternatively, the two auxiliary feeding units 200 are located on the same side of the main feeding unit 100. Alternatively, the two auxiliary feeding units 200 are respectively located on adjacent sides of the main feeding unit 100.

[0100] Alternatively, three auxiliary feeding units 200 may be provided, with each of the three auxiliary feeding units 200 located on a different side of the main feeding unit 100. Alternatively, at least two of the three auxiliary feeding units 200 may be located on the same side of the main feeding unit 100.

[0101] Alternatively, four auxiliary feeding units 200 may be provided, with each of the four auxiliary feeding units 200 located on a different side of the main feeding unit 100. Alternatively, at least two of the four auxiliary feeding units 200 may be located on the same side of the main feeding unit 100.

[0102] When two auxiliary feeding units 200 are provided and located on opposite sides of the main feeding unit 100, this layout forms a symmetrical support structure, effectively balancing the force on the panel 300 during the feeding process. This is especially suitable for feeding long or large panels 300, reducing the risk of tilting due to unilateral force. If the two auxiliary feeding units 200 are located on the same side of the main feeding unit 100, it is more suitable for handling panels 300 with a larger weight or irregular shape on one side, improving stability through concentrated support. However, attention should be paid to the potential uneven force distribution on the opposite side. When the two auxiliary feeding units 200 are located on adjacent sides of the main feeding unit 100, an L-shaped support structure can be formed, suitable for scenarios where the panel 300 needs to be supported from two directions simultaneously, such as at corners or in special process flows.

[0103] When three auxiliary feeding units 200 are provided and respectively located on different sides of the main feeding unit 100, a comprehensive support system can be formed, which is especially suitable for feeding scenarios with irregularly shaped panels 300 or requiring multi-angle positioning. The three-point support ensures that the panel 300 remains stable in any position. If at least two of the three auxiliary feeding units 200 are located on the same side of the main feeding unit 100, double support can be provided in the key stress area, while retaining auxiliary support on the other side. This is suitable for scenarios where the weight distribution of the panel 300 is uneven or requires local reinforcement.

[0104] When four auxiliary feeding units 200 are provided and respectively located on different sides of the main feeding unit 100, a complete four-sided support structure can be constructed, providing the most stable support environment for the panel 300. This is especially suitable for feeding ultra-large and ultra-heavy panels 300, maximizing pressure distribution and reducing the risk of deformation. If at least two of the four auxiliary feeding units 200 are located on the same side of the main feeding unit 100, redundant support can be formed in critical areas. For example, when the center of gravity of the panel 300 shifts, the two units can work together to prevent tipping, while retaining auxiliary support on other sides to cope with dynamic changes. In practical applications, the number and layout of the auxiliary feeding units 200 need to be comprehensively determined based on the size of the panel 300, weight distribution, process flow, and site conditions. Flexible combinations can be achieved through modular design, which can meet both standardized production needs and customized application scenarios.

[0105] Reference Figures 13 to 18 In some examples, the main feeding unit 100 also includes a flexible lifting unit 140, which is interspersed with other components and can be lifted and lowered independently. The flexible lifting unit 140 includes a lifting bracket and multiple flexible lifting rods disposed on the lifting bracket.

[0106] The flexible lifting unit 140 is designed to further enhance the adaptability and stability of the panel 300 during the loading process. The lifting bracket, as the basic structure of the flexible lifting unit 140, is made of high-strength materials to ensure stability when bearing the weight of the panel 300. Multiple flexible lifting rods are evenly distributed on the lifting bracket, each with independent lifting capabilities, allowing for precise adjustment based on the actual shape and weight distribution of the panel 300.

[0107] In practical operation, the flexible lifting rod achieves flexible lifting through elastic elements or a hydraulic / pneumatic system. It can automatically adapt to the surface unevenness of the panel 300 upon contact, avoiding damage to the panel 300 caused by rigid contact. For example, when the loading panel 300 has localized depressions or protrusions, the flexible lifting rod can maintain a tight fit with the panel 300 through its own elastic deformation, ensuring uniform transmission of lifting force. This design is particularly suitable for fragile panels 300 or scenarios requiring high surface precision, such as glass substrates and LCD panels 300.

[0108] The staggered arrangement of the flexible lifting unit 140 with other components further optimizes space utilization. By embedding the flexible lifting unit 140 within the frame of the main feeding unit 100, the overall footprint of the equipment can be reduced, while facilitating collaborative work with other components such as guide wheels and support units 230. The independent lifting function allows the flexible lifting unit 140 to remain in a low position when lifting is not required, avoiding interference with the normal feeding process, while responding quickly when needed, improving operational efficiency.

[0109] Furthermore, flexible lifting rods are typically made of wear-resistant and corrosion-resistant composite materials, such as polyurethane or high-density rubber, which ensures long-term reliability while reducing the coefficient of friction when in contact with the panel. In some high-end applications, the surface of the flexible lifting rod is also coated with a special coating to further enhance its anti-slip performance and chemical stability.

[0110] The flexible lifting unit 140 can also lift the panel 300 to a position higher than the loading platform to facilitate the transfer of the panel 300 with the transfer mechanism 400. Specifically, when the panel 300 needs to be transferred, the flexible lifting unit 140 can lift the panel 300 to a safe height higher than the loading platform according to a preset program. At this time, the transfer mechanism 400 (such as a robotic arm, vacuum suction cup, or conveyor belt) can approach the bottom of the panel 300 without obstruction and complete the transfer operation of the panel 300 by gripping, adsorbing, or lifting. This design avoids the transfer difficulties caused by insufficient height difference between the panel 300 and the platform in traditional loading mechanisms, and is especially suitable for scenarios in automated production lines that require rapid switching of workstations. For example, on a liquid crystal panel 300 production line, the flexible lifting unit 140 can lift the glass substrate to the gripping position of the robotic arm, ensuring that the robotic arm has sufficient operating space in the vertical direction, while reducing the risk of gripping failure caused by tilting or sliding of the panel 300. In addition, the independent lifting function of the flexible lifting unit 140 also supports a phased lifting strategy, that is, first slightly lifting the panel 300 to remove it from the guide wheel support, and then lifting it a second time according to the action requirements of the transfer mechanism 400, thereby further optimizing the stability and accuracy of the transfer process.

[0111] Reference Figures 17 to 18In some examples, the flexible lifting rod includes a rod body and flexible caps disposed at the ends of the rod body. Multiple flexible caps are at the same height and form a flexible lifting surface, which can lift or lower the panel 300.

[0112] The flexible lifting head is made of carefully selected materials, typically featuring high elasticity and good abrasion resistance, such as silicone or special engineering plastics. This design ensures that it provides sufficient lifting force when in contact with panel 300, while avoiding scratches or indentations on the panel 300 surface. The flush design of the flexible lifting surface allows panel 300 to remain level during lifting, preventing slippage or damage due to tilting.

[0113] In actual operation, the flexible lifting surface uses the lifting and lowering motion of the rods to smoothly lift or lower the panel 300. When the panel 300 needs to be lifted from the conveyor line for processing or inspection, the flexible lifting surface can respond quickly and evenly raise the panel 300 to ensure the accuracy of processing or inspection. After processing or inspection is completed, the flexible lifting surface can smoothly return the panel 300 to the conveyor line to continue the subsequent feeding process.

[0114] Furthermore, the design of the flexible lifting rod also takes into account ease of maintenance and replaceability. A quick-connect structure, such as a threaded connection or a snap-fit ​​connection, is typically used between the rod body and the flexible mandrel. This allows for rapid replacement when the flexible mandrel wears out or when a mandrel of a different material is needed to accommodate different panels, reducing equipment downtime and improving production efficiency.

[0115] Meanwhile, the flexible lifting unit 140 can also be equipped with sensors and a control system to achieve real-time monitoring and precise control of the lifting force. The sensors can provide real-time feedback on the contact pressure between the flexible lifting surface and the panel 300, while the control system adjusts the lifting force based on the feedback information, ensuring that the lifting process neither damages the panel 300 due to excessive force nor fails to lift due to insufficient force. This intelligent control method further improves the reliability and stability of the panel feeding mechanism.

[0116] Reference Figures 19 to 20 In some examples, the main feeding unit 100 also includes an air flotation lifting unit 150, which is interspersed with other components and lifts independently. The air flotation lifting unit 150 includes a lifting assembly, an air flotation support connected to the lifting assembly, and multiple air flotation nozzles mounted on the air flotation support. The air flotation lifting unit 150 can use negative pressure to adsorb the panel 300 during feeding or use air jet suspension to suspend the panel 300 during feeding.

[0117] The air-bearing lifting unit 150 provides a more flexible and efficient solution for loading the panel 300. As the core drive component of the air-bearing lifting unit 150, the lifting assembly typically employs a high-precision servo motor or stepper motor to ensure the smoothness and accuracy of the lifting process. Through its connection with the air-bearing bracket, the lifting assembly can drive the entire air-bearing bracket to move up and down, thereby achieving precise positioning of the panel 300.

[0118] The air flotation support, serving as the load-bearing structure for the air flotation nozzles, is designed with full consideration for the uniformity and stability of airflow distribution. Multiple air flotation nozzles are evenly distributed on the air flotation support, and each nozzle can independently control the direction and intensity of the airflow. This design allows the air flotation lifting unit 150 to perform personalized airflow adjustments based on the size, shape, and weight distribution of different panels 300, achieving better material feeding results.

[0119] In actual operation, the air flotation lifting unit 150 can load the panel 300 using either negative pressure adsorption or jet suspension. When using negative pressure adsorption, the air flotation nozzle ejects a high-speed airflow, creating a negative pressure zone on the surface of the panel 300, thus firmly adsorbing the panel 300 onto the air flotation support. This method is particularly suitable for thin and fragile panels 300, such as glass substrates and thin film materials, effectively preventing vibration and damage to the panel 300 during the loading process.

[0120] When using the jet suspension method, the air flotation nozzle continuously sprays a stable airflow, keeping the panel 300 in a suspended state. This method is suitable for heavier or irregularly shaped panels 300. Through the support of the airflow, the contact area between the panel 300 and the feeding mechanism is reduced, thereby reducing friction and wear. At the same time, the jet suspension method can also achieve rapid movement and positioning of the panel 300, improving feeding efficiency.

[0121] Furthermore, the air-float lifting unit 150 can be equipped with an intelligent control system to achieve real-time monitoring and precise control of airflow pressure, injection direction, and lifting speed. By working in conjunction with other components of the feeding mechanism, the air-float lifting unit 150 can automatically adjust its operating status according to actual needs, ensuring a smooth feeding process. This intelligent control method not only improves the automation level of the panel feeding mechanism but also further enhances its stability and reliability.

[0122] It should be noted that the air flotation lifting unit 150 is interspersed with other components and lifts independently. The air flotation support has a grid structure. Driven by the lifting assembly, the air flotation support can be raised to a height higher than the main feeding unit 100. The lifting assembly can then rotate, for example, by 30°, 45°, 60°, 75°, 90°, 135°, or 180°, before falling back to a position lower than the main feeding unit 100 to continue supporting and conveying the panel. During this process, the air flotation support can be inserted into the gaps within the main feeding unit 100. This structure allows for adjustment of the panel angle, enabling precise adjustment of the panel feeding. During adjustment, the air flotation nozzles can achieve precise timing and position of negative pressure adsorption or jet suspension under specific control, ensuring the stability and reliability of the panel orientation adjustment.

[0123] In practical operation, the air-float lifting unit 150 offers significant advantages in its configuration and movement. When the air-float support is raised above the height of the main loading unit 100 and rotated to a specified angle, the tilt direction and angle of the panel can be flexibly changed to meet the specific requirements of different production processes for panel placement. For example, in some high-precision electronic component mounting processes, the panel needs to be tilted or adjusted at a specific angle to more accurately complete the component mounting operation; the air-float lifting unit 150 can effectively achieve this function.

[0124] Once the air-bearing support falls below the position of the main feeding unit 100, the main feeding unit 100 quickly takes over the support and conveying tasks of the panel, ensuring the continuity and stability of the feeding process. The design of the air-bearing support interspersed within the gaps of the main feeding unit 100 not only saves space but also makes the structure of the entire feeding mechanism more compact and reasonable.

[0125] Meanwhile, the air flotation nozzles, under control, achieve precise timing and positioning of negative pressure adsorption or jet suspension, further enhancing the accuracy of panel orientation adjustment. Negative pressure adsorption provides stable and reliable adsorption force when panel position needs to be fixed, preventing panel displacement during adjustment; while jet suspension provides gentle and stable support force when panel position needs to be moved or adjusted, ensuring smooth panel movement. This precise control method greatly improves the efficiency and quality of panel loading, providing strong support for the smooth operation of the entire production process.

[0126] The panel feeding mechanism disclosed herein achieves several technical effects through the cooperation of the main feeding unit 100 and the auxiliary feeding unit 200: First, it can flexibly adapt to panels 300 of various sizes. The auxiliary feeding unit 200 can use the lifting structure 220 to lift the support part 230 to be flush with the main feeding platform, thereby expanding the size of the feeding platform to meet the feeding needs of panels 300 of different specifications and improving the versatility of the mechanism; Second, it can improve feeding stability. The expanded feeding platform is supported by the main body and the auxiliary support part 230 together to support the panel 300, avoiding large-size... The panel 300 is tilted or damaged due to insufficient support, ensuring a stable feeding process; thirdly, it can achieve efficient automated operation. Combined with the preset program of the control unit, it can automatically coordinate the work of the main body and auxiliary units, and can complete the switching feeding of panels 300 of different sizes without manual adjustment, thus improving processing efficiency; fourthly, it can reduce the risk of damage to the panel 300. The support part 230 adopts a guide wheel structure (such as the first and second guide wheels 233) with a flexible outer peripheral design, which reduces friction and hard contact with the panel 300 during the feeding process, protecting the surface quality of the panel 300.

[0127] The panel feeding mechanism described in this application can be applied to devices and electronic equipment related to the panel 300. Specifically, in LCD production equipment, this panel feeding mechanism can flexibly adapt to feeding LCD panels 300 of different sizes, ensuring the stability and efficiency of feeding during production, reducing production problems caused by differences in panel 300 size, and improving the production quality and efficiency of LCD displays. On tablet computer assembly lines, this panel feeding mechanism can accurately transport panels 300 of various specifications to designated positions, quickly completing the switching and feeding of panels 300 of different sizes through automated operation, reducing human error and the risk of panel 300 damage, and improving the overall assembly speed and product qualification rate of tablet computers. In the field of smartwatch manufacturing, this mechanism can also play an important role, meeting the feeding needs of smartwatch panels 300 of different sizes, and providing strong support for the efficient production of smartwatches.
