Therefore, the inventor redeveloped the structure of utility model CN2025210341294 to solve the above problem. However, when this structure is used in conjunction with the cutting machine, a sheet picker is required to pick up the sheet and send it to the cutting machine for cutting.

[0023] Specifically, such as Figures 1 to 4 As shown, an automatic glass sheet storage and cutting device includes a glass frame, a glass support that is driven by a drive device 101 to reciprocate on the glass frame, an outlet for the glass support to slide out of the glass frame on one side, a first sensor 2 at the outlet, and a fourth sensor 12 on the side of the glass frame away from the outlet; two guide rails 4 are provided on the outlet side of the glass frame, a guide support 5 corresponding to the glass support is provided between the two guide rails 4, a second sensor 3 is provided on the side of the guide support 5 away from the outlet, a sheet picker 6 is rolled on the guide rails 4, a cutter 7 is provided at the end of the guide rails 4, a third sensor 10 and a limit block 11 restricting the movement of the sheet picker are provided between the end of the guide rails 4 and the cutter 7; the glass frame 1, the sheet picker 6 and the cutter 7 are all connected to a control console 8 via signal lines; the control console 8 controls the drive device 101 to drive the glass support to the guide support 5, the sheet picker 6 moves to the glass support to pick up the original sheet and send the original sheet to the cutter 7 for cutting.
[0024] The first sensor 2, the second sensor 3, the third sensor 10, and the fourth sensor 12 are preferably photoelectric sensors or contact switches. It should be understood that the first sensor 2, the second sensor 3, the third sensor 10, and the fourth sensor 12 are devices used to detect the movement position of the glass holder or the slice taker.

[0031] The glass support includes a structure of a drive device that drives the glass support to reciprocate on the glass support, and the drive device drives the glass support to slide on the glass support. This is described in detail in Chinese Utility Model Patent CN2025210341294. To avoid conflicts with the part numbers of this utility model, the original reference numbers have been deleted from the following specific references, while the names remain consistent with the original text. The specific references are as follows:
[0032] The drive unit is connected to the glass sheet storage control system to receive or provide feedback control signals and control the automatic feeding of sheets by the sliding frame. It should be understood that the drive unit includes a driver and a transmission device. The driver is a motor, and its power and control lines are connected to the glass sheet storage control system. The control system transmits control commands to the motor via the control and power lines. For example, it controls the motor's forward and reverse rotation via the power line, or it sends control commands to the motor to adjust its speed. Furthermore, the motor's speed is detected by a sensor and fed back to the control system via the control line, achieving feedback adjustment. The input end of the transmission device is connected to the driver, and its output end is fixedly connected to the base or sliding frame.
[0033] Specifically, the guiding device includes two structural forms: guide rods and guide grooves.
[0034] The first structural form is the guide groove structure. The guide groove is set on the top surface of the longitudinal beam, the side surface of the longitudinal beam, or between two longitudinal beams. This embodiment takes the side surface of the longitudinal beam as an example for explanation. The other two structural forms are similar to this embodiment. The guiding device includes a guide groove, which is set on the side surface of the longitudinal beam. A guide wheel is rolled in the guide groove, and the axle of the guide wheel is fixedly connected to the side surface of the base of the sliding frame. Preferably, the guide grooves are arranged in pairs and symmetrically on the side of the rectangular frame-shaped base.
[0035] The second structural form is the guide rod structure. The guide rod is set on the top surface of the longitudinal beam, the side surface of the longitudinal beam, or between two longitudinal beams. This embodiment takes the side surface of the longitudinal beam as an example for explanation. The other two structural forms are similar to this embodiment. The guiding device includes a guide rod, which is set on the side surface of the longitudinal beam. A guide seat is sleeved on the outer circumference of the guide rod, and the guide seat is fixedly connected to the side surface of the base of the sliding frame.
[0036] Specifically, the sliding frame is driven by a drive device and reciprocates along the guide device; the drive device is fixedly connected to the base or the sliding frame. It should be understood that the drive device can be fixed to the base or the sliding frame, but when the drive device outputs power, it enables the sliding frame to slide within the base, thus achieving automatic glass sheet feeding in the storage without requiring external equipment to apply pushing or pulling force to the sliding frame. This embodiment provides four structural forms for the drive device, but is not limited to these four forms. Any structure that enables the sliding frame to slide within the base when the drive device outputs power is within the scope of protection of this application. The four structural forms provided in this embodiment are used to illustrate that it is feasible to enable the sliding frame 2 to slide within the base when the drive device outputs power, not to limit it.
[0037] The drive unit includes a driver and a transmission; the driver is a motor or electric motor, meaning that motors and electric motors can be interchanged; the input end of the transmission is connected to the driver, and the output end of the transmission is fixedly connected to the base or sliding frame.
[0038] In the first scenario, when the driver of the drive unit is fixedly connected to the sliding frame, the driver is fixed to the top side of the base of the sliding frame. The output end of the driver is equipped with a gear, and the top side of the base is equipped with a rack. The gear and rack mesh, driving the sliding frame to reciprocate along the guide device. Specifically, the driver is a motor, which is fixed to the top of the sliding frame. The motor can be directly connected to the gear, or its direction can be changed through a bevel gear set according to the specific structure, thereby changing the position of the motor. The top side of the base is equipped with a rack, and the gear and rack mesh. When the motor drives the gear to roll on the rack, it drives the sliding frame to reciprocate along the guide device.
[0039] The second configuration involves a driver unit fixedly connected to the base. The driver unit's output end is equipped with a first synchronous pulley, meaning the motor's output end is also equipped with a first synchronous pulley. The base does not fix the driver unit, meaning one end of the motor is equipped with a second synchronous pulley. A synchronous belt connects the first and second synchronous pulleys. A synchronous belt support beam is also provided at the bottom of the synchronous belt to hold and support it, preventing sagging. The synchronous belt and the bottom of the base 3 of the sliding frame are connected by a first fixing block. The forward and reverse rotation of the synchronous belt drives the sliding frame to reciprocate along the guide device. The motor is fixed to the end of the base by a second fixing plate.
[0040] The third type involves a drive unit whose driver is fixedly connected to the base. The driver, i.e., the output end of the motor, is equipped with a first sprocket, and the end of the base where the driver is not fixed is equipped with a second sprocket. A chain connects the first and second sprockets. The chain and the bottom of the base of the sliding frame are connected by a second fixing block. The forward and reverse rotation of the chain drives the sliding frame to reciprocate along the guide device. The motor is fixed to the end of the base by a first fixing plate.
[0041] Preferably, the chain is a double-row chain, the first sprocket and the second sprocket are double-row sprockets, and the chain is a double-speed chain.
[0042] The fourth type involves a drive unit whose driver is fixedly connected to the base. The driver, i.e., the output end of the motor, is fixedly connected to the lead screw. The end of the base where the driver is not fixed is equipped with a bearing, which is connected to the lead screw. A threaded sleeve is fitted on the outside of the lead screw. The threaded sleeve is fixed inside the third fixed block. The bottom of the base of the sliding frame is fixedly connected to the third fixed block through a connecting block. The forward and reverse rotation of the lead screw inside the threaded sleeve drives the sliding frame to reciprocate along the guide device. The motor is fixed to the end of the base through the third fixed plate.
[0043] Furthermore, the structure of the slicer and cutter is described in detail in Chinese utility model patent CN202021282456.9; to avoid conflicts with the part designations of this utility model, the original designations have been deleted from the following specific references, while the names remain consistent with the original text. The content of the specification cited in CN202021282456.9 is as follows:
[0044] A novel adsorption glass cutting machine includes a glass cutting machine, a first hydraulic rod, a dual-head motor, a second hydraulic rod, and a suction cup. The first hydraulic rod is fixedly installed inside the right end of the glass cutting machine, and a straight plate is fixedly installed at the right end of the first hydraulic rod. A connecting frame is fixedly installed on the right surface of the straight plate. The right end of the connecting frame is connected to the bottom end of a first support frame. The dual-head motor is fixedly installed at the bottom end of the first support frame, and connecting shafts are installed at both the front and rear ends of the dual-head motor. The connecting shafts pass through the first support frame and are fixedly connected to a first positioning plate. A frame is connected to the right end of the first positioning plate, and the frame is rotatably connected to the top end of the first support frame via a second positioning plate. The second hydraulic rod is fixedly installed on the left side of the top end of the first support frame, and the bottom end of the second hydraulic rod is connected to the first connecting plate. The right end of the first connecting plate is connected to the first support frame. A second connecting plate is provided at the left end of the first connecting plate, and the left end of the second connecting plate is fixedly connected to the front output shaft of a servo motor.
[0045] The straight plate and connecting frame are in a sliding structure with the glass cutting mechanism, and the right end of the connecting frame is connected to the first support frame by a rotating connection, which is beneficial for the subsequent work of pushing the frame to move left and right, and at the same time facilitates the rotation of the first support frame on the connecting frame.
[0046] The first positioning plates are symmetrically distributed about the longitudinal centerline of the first support frame, and the connection between the first positioning plates and the frame is a rotating connection, which is beneficial for the first positioning plates to drive the frame to move during rotation, making it convenient for fine-tuning the frame.
[0047] A fixed shaft is fixedly installed on the right surface of the frame, and a circular plate is fixedly installed on the outer surface of the fixed shaft. The right end of the fixed shaft is connected to a connecting hole, which is located at the center of the left end of the positioning plate. A suction cup is provided on the right surface of the positioning plate, which facilitates the subsequent adsorption of glass by the suction cup on the frame and makes automatic feeding convenient.
[0048] The second hydraulic rod is rotatably connected to the first support frame and the first connecting plate, and the first connecting plate is rotatably connected to the first support frame and the second connecting plate. This facilitates the rotation of the second connecting plate by the operation of the servo motor, and makes it convenient for the second connecting plate to drive the first support frame to rotate for storage and unfolding, which is beneficial to the overall operation.
[0049] The fixed shafts are evenly distributed on the frame, and the diameter of the fixed shafts is smaller than the diameter of the circular plate. The fixed shafts are connected to the positioning plate through the connecting holes by a threaded connection. At the same time, the positioning plate and the suction cup are integrated into one structure, which facilitates the replacement of the suction cup after it wears out. It can also locate the installation position of the suction cup to ensure the flatness of the suction cup after installation.
[0050] Working Principle: First, the operator activates the first hydraulic rod, which pushes the connecting frame to the right via a straight plate. This causes the connecting frame to move the first support frame and the main frame to the right, facilitating the connection between the suction cup and the external glass. Next, the dual-head motor is activated, causing the first positioning plate to rotate. This allows the first positioning plate to adjust the main frame. Simultaneously, the second positioning plate increases the stability of the adjustment, ensuring the suction cup fully adheres to the external glass for suction. Then, following the same principle, the system resets using the dual-head motor and the first hydraulic rod. Finally, the servo motor is activated, causing the first support frame to rotate and retract on the connecting frame via the first and second connecting plates. The first support frame is conveniently stored inside the glass cutting machine, which facilitates the flat placement of the adsorbed glass onto the machine for subsequent processing. The glass cutting machine, the first hydraulic rod, and the double-headed motor are known and existing technologies on the market and will not be described in detail here. When the suction cup is worn and needs to be replaced, the positioning plate is manually rotated to separate it from the fixed shaft through the connecting hole, thus completing the disassembly. Then, the intact suction cup is threaded to the fixed shaft through the connecting hole on the positioning plate. At the same time, the circular plate on the fixed shaft can be used to position the entire installation, ensuring overall flatness. This is the working process of the entire device.
[0051] It is worth mentioning that CN202021282456.9 describes in detail the structure and action of the sheet-grabbing machine. For this utility model, these descriptions are precisely the structure and action of the sheet-grabbing machine, which is also the structure and action adopted by this utility model. For the cutting machine, it is the remaining function and structure after removing the structure and action of grabbing the glass sheet in CN202021282456.9. The cutting machine includes a Cartesian coordinate system action module. At the execution head of the action module, a cutting head is fixed to perform cutting. The Cartesian coordinate system action module is existing technology, that is, the Cartesian coordinate robotic arm that is popular in the market, which is well known to those skilled in the art, and will not be described in detail here.
