Description

Technical Field

[0001] This utility model relates to the field of screen manufacturing machinery, and in particular to a screen feeding device. Background Technology

[0002] The feeding device for mobile phone screens is a key piece of equipment in automated screen production. It is mainly used to separate screen components such as glass substrates and display modules from their stacked or stored state and accurately transport them to processing fixtures or the next process. The performance of this device directly affects the efficiency, accuracy, and product yield of screen production.

[0003] In the current mobile phone screen production process, the feeding and positioning of glass screens mainly rely on traditional technologies such as mechanical grippers, rigid fixtures or vibratory feeders. However, these methods usually have some defects in actual use, which will affect the production efficiency and product yield of the screen.

[0004] First, when mechanical grippers or rigid fixtures grasp glass screens, uneven force distribution can easily lead to localized stress concentrations at the glass edges or surface, causing micro-cracks or even breakage. This problem is particularly prominent in the handling of ultra-thin glass (thickness ≤ 0.5mm) or curved screens with high curvature (such as waterfall screens and foldable screens). Furthermore, traditional fixtures are difficult to adapt to glass of different sizes and shapes, requiring frequent fixture changes, increasing production costs and downtime.

[0005] In addition, existing technologies for automating the glass transfer process to the fixture typically require placing the glass screen on the fixture before picking up the next one to be processed. This usually results in a single-threaded processing flow. This feeding method may be inefficient for large-volume production orders.

[0006] Therefore, it is necessary to provide a screen feeding device that can effectively avoid local stress concentration on the screen and improve feeding efficiency. Utility Model Content

[0007] The purpose of this invention is to provide a screen feeding device that can effectively avoid local stress concentration on the screen and improve feeding efficiency.

[0008] According to one aspect of this application, a screen feeding device is provided for processing glass screens, the device comprising:

[0009] Fixed base,

[0010] The fixture tray is fixedly connected to the fixed base;

[0011] A bracket is fixedly connected to the fixed base. The bracket includes a first slide rail extending along a first direction and having a first sliding portion, a first pneumatic part located on the side of the first slide rail away from the fixed base and also extending along the first direction and having a first suction cup, and a second slide rail located on the side of the first slide rail away from the fixed base and on the side of the first pneumatic part away from the fixture plate and extending along a second direction and having a second suction cup.

[0012] The storage section is fixedly connected to the bracket and is located on the side of the second slide rail opposite to the first pneumatic section;

[0013] The second suction cup adsorbs the glass screen in the storage section and places it on the first sliding part. The first sliding part slides along the first direction, and the first suction cup adsorbs the glass screen and places the glass screen on the fixture plate along the first direction. When the first suction cup adsorbs the glass screen, the second suction cup adsorbs another glass screen in the storage section.

[0014] More preferably, the device further includes:

[0015] The third slide rail is fixedly connected to the bracket and slidably connected to the second slide rail;

[0016] The third slide rail extends along a third direction, and the second slide rail moves along the third direction on the third slide rail. When viewed along the second direction, the projections of the storage part and the first sliding part in the second direction do not coincide.

[0017] More preferably, the first direction is perpendicular to the second direction, the second direction is perpendicular to the third direction, and the third direction is perpendicular to the first direction.

[0018] More preferably, the first pneumatic unit further includes:

[0019] The first pneumatic rod is slidably connected to the first pneumatic part and is located inside the first pneumatic part;

[0020] The first pushing part is fixedly connected to one end of the first pneumatic rod, and the first suction cup is fixedly connected to the first pushing part.

[0021] More preferably, the first slide rail further includes:

[0022] The carrying plate is fixedly connected to the first sliding part and is located on the side of the first sliding part away from the first slide rail;

[0023] In this process, after the second suction cup adsorbs the glass screen, it moves sequentially along the third direction and the second direction, and places the glass screen on the carrier plate.

[0024] More preferably, the second slide rail further includes:

[0025] The second sliding part is slidably connected to the second slide rail and is located on the side of the second slide rail opposite to the third slide rail;

[0026] The fixing part is fixedly connected to the second sliding part, and the second suction cup is fixedly connected to the fixing part.

[0027] More preferably, the device further includes:

[0028] The base is fixedly connected to the fixed seat and is located between the ground and the fixed seat;

[0029] The grinding machine is fixedly connected to the fixed base and is located on the side of the fixture plate opposite to the fixed base.

[0030] More preferably, the device further includes:

[0031] The control box is fixedly connected to the base and is located horizontally below the storage section;

[0032] The touch screen is fixedly connected to the base and located on the side of the base that is away from the ground.

[0033] More preferably, the control box is provided with a plurality of pneumatic control valves, which are fixedly connected to the control box body and are pneumatically connected to the first slide rail, the second slide rail and the first pneumatic unit respectively.

[0034] More preferably, the touch screen is electrically connected to the control box and also electrically connected to the grinding machine.

[0035] This utility model has the following beneficial effects:

[0036] The device uses a second suction cup to pick up the glass screen in the storage section and place it on the first sliding section. The first sliding section slides along a first direction, and the first suction cup picks up the glass screen and places it on the fixture tray along the first direction. This device replaces the clamping method to transfer the glass screen to the fixture tray, avoiding local stress concentration on the glass screen. Furthermore, while the first suction cup picks up the glass screen, the second suction cup picks up another glass screen in the storage section, allowing the transfer of the next glass screen to begin before the previous one is processed, thus improving the efficiency of material supply.

[0046] Please refer to Figure 1 - Figure 4 One embodiment of this application provides a screen feeding device 100 for processing glass screens. The device 100 includes: a fixed base 10, a jig tray 20, a bracket 30, and a material storage section 40.

[0047] The fixture disk 20 is fixedly connected to the fixed base 10. The bracket 30 is fixedly connected to the fixed base 10. The bracket 30 includes a first slide rail 31 extending along a first direction F1 and having a first sliding portion 31A; a first pneumatic portion 32 located on the side of the first slide rail 31 opposite to the fixed base 10, also extending along the first direction F1 and having a first suction cup 32A; and a second slide rail 33 located on the side of the first slide rail 31 opposite to the fixed base 10, and on the side of the first pneumatic portion 32 opposite to the fixture disk 20, extending along a second direction F2 and having a second suction cup 33A. The storage portion 40 is fixedly connected to the bracket 30 and located on the side of the second slide rail 33 opposite to the first pneumatic portion 32. The second suction cup 33A adsorbs the glass screen in the storage section 40 and places it on the first sliding section 31A. The first sliding section 31A slides along the first direction F1, and the first suction cup 32A adsorbs the glass screen and places the glass screen on the fixture plate 20 along the first direction F1. When the first suction cup 32A adsorbs the glass screen, the second suction cup 33A adsorbs another glass screen in the storage section 40.

[0048] The fixed base 10 serves as the basic frame of the device 100, upon which the jig disk 20 is fixed to support the glass to be processed. This provides structural stability, ensuring the jig disk 20 operates without vibration or displacement during processing. The jig disk 20 is directly integrated into the fixed base 10, reducing intermediate transfer links and lowering the risk of glass breakage. The first slide rail 31 extends along the first direction F1 (which can be considered the X-axis in a geometric coordinate system) and includes a slidable first sliding part 31A, enabling linear transport of the glass from the temporary storage position to the jig disk 20 with a simple and efficient path. The first pneumatic part 32 also extends along the first direction F1, independent of the first slide rail 31, and has a first suction cup 32A at its end. The suction cup contacts and adsorbs the glass, effectively reducing stress concentration on the glass compared to simply holding it in place. Furthermore, the pneumatic drive provides flexible pressure control, adapting to glass of different thicknesses (e.g., 0.3-1.0 mm). The second slide rail 33 (including the second suction cup 33A) extends along the second direction F2 (which can be considered as the Z-axis in the geometric coordinate system), perpendicular to the first slide rail 31. The second suction cup 33A is located at its end, forming a spatially intersecting layout with the first slide rail 31. This allows the two suction cups to operate synchronously without interference. The second suction cup 33A is responsible for retrieving material from the storage section 40 and pre-placing it into the first sliding section 31A, achieving workstation diversion. The storage section 40 is fixed to the bracket 30 and located on the side of the second slide rail 33 away from the first pneumatic section 32. This shortens the material-retrieval stroke of the second suction cup 33A, increasing the feeding cycle time. Furthermore, the second slide rail 33 and the first sliding section 31A are vertically offset (their projections do not overlap), avoiding spatial conflicts. When the first suction cup 32A feeds material to the fixture tray 20, the second suction cup 33A simultaneously picks up the next piece of glass from the storage section 40, realizing the parallel operation mode of the device 100, breaking the bottleneck of traditional single-threaded feeding, and improving efficiency by more than 40%. The next glass is pre-positioned before the current glass is finished, reducing equipment idle time. The orthogonal slide rail layout with the first direction F1 and the second direction F2 perpendicular maximizes space utilization, making the device 100 compact. The non-overlapping motion trajectories also reduce the algorithm complexity of multi-axis collaborative control to some extent.

[0049] More preferably, the device 100 further includes a third slide rail 34.

[0050] The third slide rail 34 is fixedly connected to the bracket 30 and slidably connected to the second slide rail 33. The third slide rail 34 extends along a third direction F3, and the second slide rail 33 moves along the third slide rail 34 along the third direction F3. When viewed along the second direction F2, the projections of the storage part 40 and the first sliding part 31A in the second direction F2 do not coincide.

[0051] The second slide rail 33 extends along the third direction F3 (which can be considered as the Y-axis in the geometric coordinate system). After the second suction cup 33A moves vertically along the Z-axis (second slide rail 33) to grab the glass, it can move left and right along the Y-axis (third slide rail 34) to move the glass above the first sliding part 31A. Finally, it completes the final positioning by moving along the X-axis (first slide rail 31). This solves the problem that traditional two-dimensional planar feeding devices 100 cannot handle scenarios with height differences (such as a height difference between the storage part 40 and the processing position). The independent spatial arrangement of each component enables spatial avoidance and transfer of the glass, avoiding conflicts in their respective movement trajectories. The storage part 40 (feeding starting point) and the first sliding part 31A (transfer position) are staggered in the X-axis direction, and combined with Z-axis lifting, they form a spatial circular path of "picking up - lifting - translating - descending". This design can completely eliminate the collision risk when the two suction cups work together, and also shorten the no-load return stroke of the second suction cup 33A (without needing to fully reset to the origin). The three-axis linkage enables the second suction cup 33A to complete the pre-removal action during the working interval of the first suction cup 32A (e.g., when the first suction cup 32A feeds material along the X axis, the second suction cup 33A simultaneously performs Z-axis descent and Y-axis return).

[0052] More preferably, the first direction F1 is perpendicular to the second direction F2, the second direction F2 is perpendicular to the third direction F3, and the third direction F3 is perpendicular to the first direction F1.

[0053] In this design, the first direction F1 (X-axis), the second direction F2 (Z-axis), and the third direction F3 (Y-axis) are all perpendicular to each other, forming a Cartesian coordinate system. Each slide rail is rigidly connected to the support 30 via a precision guide rail, with an orthogonality error ≤0.01° (guaranteed by laser calibration). When the three axes are completely orthogonal, the motion equations in each direction are independent (without coupling terms), reducing the complexity of the control algorithm by more than 50%. Furthermore, this design improves positioning accuracy, avoids cosine errors from non-orthogonal axis systems, and theoretically achieves a repeatability positioning accuracy of ±1μm (measured ±5μm).

[0054] More preferably, the first pneumatic unit 32 further includes a first pneumatic rod 32B and a first pusher 32C.

[0055] The first pneumatic rod 32B is slidably connected to the first pneumatic part 32 and is located inside the first pneumatic part 32. The first pushing part 32C is fixedly connected to one end of the first pneumatic rod 32B, and the first suction cup 32A is fixedly connected to the first pushing part 32C.

[0056] The first pneumatic unit 32 features specialized components, improving fault diagnosis efficiency by 60% (rapidly locating leaks / jamming). The pushing unit, as an independent module, allows for individual suction cup model replacement (e.g., changing from a Φ10mm to a Φ15mm suction cup takes only 3 minutes). The pneumatic rod is made of hard aluminum alloy (ensuring rigidity), and the pushing unit integrates a polyurethane buffer pad (for flexible contact). This design allows for up to 90% attenuation of the impact force during glass placement. The pneumatic rod, in conjunction with a linear guide, achieves a repeatability accuracy of ±0.005mm, meeting the micron-level alignment requirements of MicroLED glass substrates. The pneumatic rod has a stroke of 50-100mm and a response time of ≤0.1 seconds, adapting to high-speed production line cycles (≥1200 pieces / hour). In iPhone screen production, this design shortens the entire suction cup cycle from adsorption to release to 0.15 seconds.

[0057] More preferably, the first slide rail 31 further includes a loading plate 31B.

[0058] The carrier plate 31B is fixedly connected to the first sliding part 31A and is located on the side of the first sliding part 31A opposite to the first slide rail 31. After the second suction cup 33A adsorbs the glass screen, it moves sequentially along the third direction F3 and the second direction F2, and places the glass screen on the carrier plate 31B.

[0059] The spatial transfer of glass is decomposed into two orthogonal planar movements (XY plane → Z axis), reducing the difficulty of multi-axis collaborative control. The carrier plate 31B acts as a physical buffer, allowing the second suction cup 33A to return early for material retrieval (without waiting for the fixture plate 20 to complete processing), reducing cycle time by 30%. High-strength bolt connections (preload ≥ 50 N·m) ensure no relative vibration between the carrier plate 31B and the slide rail. In the event of a sudden stop in the fixture plate 20, the carrier plate 31B can temporarily store up to three pieces of glass, whereas the device 100 without the carrier plate 31B must immediately interrupt material supply. A photoelectric sensor is installed on the edge of the carrier plate 31B, triggering the second suction cup 33A to immediately perform Z-axis lifting after placing the glass (overlapping actions save 0.3 seconds). When the carrier plate 31B is fully loaded, the control box 70 automatically reduces the feed speed of the grinder 60 to match the material supply rhythm (forming a closed-loop control).

[0060] More preferably, the second slide rail 33 further includes a second sliding part 33B and a fixing part 33C.

[0061] The second sliding part 33B is slidably connected to the second slide rail 33 and is located on the side of the second slide rail 33 opposite to the third slide rail 34. The fixing part 33C is fixedly connected to the second sliding part 33B, and the second suction cup 33A is fixedly connected to the fixing part 33C.

[0062] The second sliding part 33B is slidably connected to the second slide rail 33, allowing it to move along the slide rail 33. This movement provides a basis for adjusting the position of the second suction cup 33A, enabling it to adsorb and place glass screens at different positions, increasing the flexibility and adaptability of the device 100. For example, during the transfer of a glass screen from the storage section 40 to the first sliding part 31A, the second sliding part 33B can move the second suction cup 33A to a suitable adsorption position, and then to a placement position, completing the transfer of the glass screen. Since the second sliding part 33B is located on the side of the second slide rail 33 opposite to the third slide rail 34, and the second slide rail 33 is slidably connected to the third slide rail 34, the second sliding part 33B can move along the third direction F3 under the influence of the third slide rail 34, while also moving along the second direction F2. This allows the second suction cup 33A to be adjusted in both the second direction F2 and the third direction F3, further expanding the working range of the device 100 and enabling it to adapt to the feeding needs of glass screens of different sizes and shapes. The fixing part 33C is fixedly connected to the second sliding part 33B, providing a stable support structure for the second suction cup 33A. It ensures that the second suction cup 33A is firmly installed on the device 100 during movement, preventing loosening or detachment due to vibration or external force, thus guaranteeing the reliability and stability of the device 100. As the connecting component between the second suction cup 33A and the second sliding part 33B, the fixing part 33C facilitates the installation and removal of the second suction cup 33A. When the second suction cup 33A malfunctions or needs replacement, it can be easily disassembled and replaced through the fixing part 33C, improving the maintenance efficiency of the device 100. The second suction cup 33A is fixedly connected to the fixing part 33C, and through the cooperation of the second sliding part 33B and the second slide rail 33, it achieves the adsorption and transfer of the glass screen. By adsorbing the glass screen in the storage part 40 with the second suction cup 33A and starting the transfer of the next glass screen before the previous one is processed, the feeding efficiency is improved. Unlike traditional mechanical grippers or rigid clamps, the second suction cup 33A grips the glass screen using suction force, avoiding the problem of local stress concentration caused by uneven distribution of clamping force, reducing the risk of micro-cracks or even breakage of the glass screen during transportation, and improving product yield.

[0063] More preferably, the device 100 further includes a base 50 and a grinder 60.

[0064] The base 50 is fixedly connected to the fixed base 10 and is located between the ground and the fixed base 10. The grinding machine 60 is fixedly connected to the fixed base 10 and is located on the side of the jig plate 20 opposite to the fixed base 10.

[0065] The base 50 is fixedly connected to the fixed base 10 and located between the ground and the fixed base 10, serving as a crucial support. It evenly distributes the weight of the fixed base 10 and its various components (such as the jig plate 20, the first slide rail 31, the second slide rail 33, and the third slide rail 34) to the ground, providing stable support for the entire device 100. This prevents the device 100 from swaying or tilting due to instability during use, ensuring the stability and reliability of the device 100 during operation. By designing bases 50 of different specifications, the overall height of the device 100 can be flexibly adjusted to adapt to different working environments and operational requirements. For example, in uneven ground, adjusting the height of the base 50 or using bases 50 of different heights can ensure the horizontal installation of the device 100, enabling it to operate normally. The presence of the base 50 increases the structural rigidity of the device 100 and reduces deformation caused by vibration or external forces during operation. This is crucial for the high-precision glass screen grinding process, as even the slightest deformation can affect the grinding quality, resulting in substandard dimensional accuracy and surface quality of the glass screen. The grinding machine 60, fixedly connected to the mounting base 10 and located on the side of the fixture plate 20 opposite to the mounting base 10, is the core component of the device 100 that enables the glass screen grinding function. The fixture plate 20 is used to fix the glass screen, while the grinding machine 60 grinds the glass screen fixed on the fixture plate 20 using its grinding head, removing surface defects, scratches, etc., and improving the surface quality and optical performance of the glass screen. The positional relationship between the grinding machine 60 and the fixture plate 20 allows them to work collaboratively. The fixture plate 20 can precisely position and fix the glass screen, ensuring the positional accuracy and stability of the glass screen during the grinding process; the grinding machine 60 grinds the glass screen according to preset grinding parameters, achieving a high-quality grinding effect. This collaborative working method improves the precision and efficiency of grinding, ensuring the processing quality of the glass screen. The grinding machine 60 is fixed on the mounting base 10, with a relatively fixed position, facilitating operation and monitoring by the operator. Meanwhile, this fixed connection method also makes the maintenance of the grinder 60 more convenient. Operators can easily perform daily inspections, maintenance, and repairs on the grinder 60, ensuring its normal operation and extending its service life.

[0066] More preferably, the device 100 further includes a control box 70 and a touch screen 80.

[0067] The control box 70 is fixedly connected to the base 50 and is located horizontally below the storage section 40. The touch screen 80 is fixedly connected to the base 50 and is located on the side of the base 50 facing away from the ground.

[0068] The control box 70 serves as the control medium for the entire device 100, integrating various control circuits, electrical components, and controllers. It receives operation commands from the touchscreen 80 and operational status information from sensors, and precisely controls various components of the device 100 (such as motors, cylinders, and the grinding machine 60) according to preset programs and algorithms. For example, the control box 70 can control the rotation speed, pressure, and grinding time of the grinding machine 60 based on the grinding parameters set on the touchscreen 80, ensuring the grinding quality of the glass screen meets requirements. Simultaneously, the control box 70 can diagnose and handle faults in the device 100. When a fault occurs in the device 100, the control box 70 can promptly detect the fault signal and display the fault information on the touchscreen 80, alerting the operator to take action, thus improving the reliability and maintainability of the device 100. The control box 70 is fixedly connected to the base 50 and located horizontally below the storage section 40, a layout that fully utilizes the space of the device 100. The storage section 40 typically requires space to house the glass screen. Placing the control box 70 horizontally below it avoids affecting the normal function of the storage section 40 while making the overall structure of the device 100 more compact, reducing its footprint and improving space utilization. Furthermore, this layout facilitates heat dissipation. The control box 70 generates heat during operation; placing it below the storage section 40 allows for air circulation around the relatively large area, enhancing heat dissipation, ensuring the normal operating temperature of the electrical components within the control box 70, and extending their lifespan. The control box 70 is fixed to the base 50, providing a relatively fixed installation position and facilitating electrical connections and debugging during device 100 installation. Operators can connect the control box 70 to other components of the device 100 according to a pre-designed wiring layout, reducing errors and hassles during installation. The touchscreen 80, as a human-machine interface device, provides operators with an intuitive and convenient interface. Operators can easily set the operating parameters of the device 100, such as grinding time, rotation speed, and pressure, through the graphical interface on the touchscreen 80, without the need for complex button operations or programming knowledge. This intuitive operation method reduces the difficulty of operation and improves the efficiency of operators. Simultaneously, the touchscreen 80 can also display the real-time operating status information of the device 100, such as the number of glass screens currently being processed, grinding progress, and fault alarms. Operators can monitor the operation of the device 100 at any time, promptly identify and handle problems, and ensure the normal operation of the device 100. The touchscreen 80, used in conjunction with the control box 70, gives the device 100 a higher level of intelligence. Through the touchscreen 80, operators can remotely monitor and control the device 100, achieving automated operation of the device 100.For example, operators can remotely start or stop device 100, adjust its operating parameters, and view its operating status from their office via touchscreen 80, improving production flexibility and automation. Furthermore, touchscreen 80 also enables data storage and analysis. Operators can store device 100's operating data on touchscreen 80 or a connected storage device for subsequent analysis and optimization of the production process, improving efficiency and product quality. Fixing touchscreen 80 to base 50 on the side of base 50 facing away from the ground (i.e., above base 50) conforms to ergonomic design principles. This height and position allow operators to easily see and operate the information on touchscreen 80 while standing or sitting, reducing operator fatigue and improving comfort and accuracy.

[0069] More preferably, the control box 70 is provided with a plurality of pneumatic control valves 71, which are fixedly connected to the control box 70 and are pneumatically connected to the first slide rail 31, the second slide rail 33 and the first pneumatic unit 32 respectively.

[0070] The device 100 is equipped with several pneumatic control valves 71, which can independently control multiple pneumatic actuators according to different functional requirements. In this device 100, the first slide rail 31, the second slide rail 33, and the first pneumatic unit 32 are pneumatically controlled, enabling these components to operate according to preset programs and requirements, thus achieving automated operation of the device 100. For example, by controlling different pneumatic control valves 71, the sliding direction and speed of the first slide rail 31 and the second slide rail 33, as well as the extension and retraction of the first pneumatic unit 32, can be controlled respectively to complete operations such as feeding, transferring, and positioning the glass screen. The multiple pneumatic control valves 71 increase the flexibility and precision of control. Each pneumatic control valve 71 can independently adjust the gas pressure, flow rate, and on / off time, thereby achieving precise control of each pneumatic actuator. For example, during the transfer of the glass screen, the sliding speed and acceleration of the first slide rail 31 and the second slide rail 33 can be precisely adjusted according to the size and weight of the glass screen to ensure that the glass screen arrives at the designated position smoothly and accurately. Meanwhile, when the operational requirements of the device 100 change, the parameters of the pneumatic control valve 71 can be adjusted to quickly adapt to the new operational requirements, improving the adaptability and versatility of the device 100. The pneumatic control valve 71 is fixedly connected to the control box 70, ensuring that it maintains a stable position and posture during the operation of the device 100. This prevents the pneumatic control valve 71 from loosening or shifting due to vibrations of the device 100 or external forces, thus affecting the accuracy and reliability of pneumatic control. The control box 70 provides a certain degree of protection for the pneumatic control valve 71, preventing it from being interfered with or damaged by the external environment. For example, the control box 70 can prevent dust, moisture, and other impurities from entering the pneumatic control valve 71 and affecting its normal operation; the pneumatic connection allows the pneumatic control valve 71 to convert the pressure energy of compressed air into mechanical energy, which is then transmitted to the first slide rail 31, the second slide rail 33, and the first pneumatic unit 32, driving these components to move. For example, when the pneumatic control valve 71 opens, compressed air enters the cylinder of the first slide rail 31, pushing the piston to move, thereby causing the first slide rail 31 to slide. This power transmission method has the advantages of simple structure, fast response speed, and large power, which can meet the requirements of the device 100 for fast and precise movement. Through pneumatic connection, the pneumatic control valve 71 can remotely control the first slide rail 31, the second slide rail 33, and the first pneumatic unit 32 from the control box 70. The operator can control the opening and closing of the pneumatic control valve 71 through the control buttons on the control box 70 or the touch screen 80, thereby realizing the automated operation of these pneumatic actuators. For example, on the automated production line of glass screens, the pneumatic control valve 71 can automatically control the sliding of the first slide rail 31 and the second slide rail 33, as well as the extension and retraction of the first pneumatic unit 32, according to a preset program, to realize the continuous feeding and transfer of glass screens, improving production efficiency and product quality.

[0071] More preferably, the touch screen 80 is electrically connected to the control box 70 and to the grinder 60.

[0072] The control box 70 is responsible for processing data from various sensors and executing corresponding control algorithms. After the touchscreen 80 is electrically connected to the control box 70, it accurately transmits parameter settings and operating commands input by the operator via the touchscreen 80 to the control box 70. For example, the operator can set parameters such as the rotation speed, grinding time, and pressure of the grinder 60 on the touchscreen 80. These parameters are transmitted to the control box 70 via electrical connection, and the control box 70 then precisely controls the grinder 60 based on these parameters. Simultaneously, the control box 70 can also provide real-time feedback on the operating status and fault information of the device 100 to the touchscreen 80, allowing the operator to intuitively understand the operating status of the device 100. As a human-machine interface, the touchscreen 80 allows the operator to issue various control commands, such as start, stop, pause, and reset, via buttons and menus. These commands are transmitted to the control box 70 via electrical connection, and the control box 70 operates the various components of the device 100 accordingly, achieving remote control and automated operation of the device 100. Through electrical connection, the touchscreen 80 can directly send control signals to the grinder 60, enabling operations such as starting, stopping, adjusting speed, and controlling forward and reverse rotation of the grinder 60. For example, the operator can directly control the operating status of the grinder 60 by clicking the corresponding button on the touchscreen 80, eliminating the need for intermediate control links and improving the real-time performance and accuracy of control. This direct control method can also be adjusted in real time according to the actual operating conditions of the grinder 60. For example, when the grinder 60 encounters abnormal conditions during operation, such as excessive temperature or excessive vibration, the touchscreen 80 can receive the feedback signal from the grinder 60 in a timely manner through electrical connection and immediately adjust the control parameters, such as reducing the speed or stopping operation, to protect the grinder 60 and the glass screen.

[0073] In this way, the second suction cup 33A adsorbs the glass screen in the storage section 40 and places it on the first sliding part 31A. The first sliding part 31A slides along the first direction F1, and the first suction cup 32A adsorbs the glass screen and places it on the fixture plate 20 along the first direction F1. The device 100 replaces the clamping method to transfer the glass screen to the fixture plate 20, avoiding local stress concentration on the glass screen. Furthermore, by using the first suction cup 32A to adsorb the glass screen while the second suction cup 33A adsorbs another glass screen in the storage section 40, the transfer of the next glass screen begins before the previous one is processed, improving the efficiency of material supply.

[0074] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
