[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] Example: This invention provides a technical solution for a glass substrate grinding and pre-wetting cleaning system, such as... Figures 1-14As shown, it includes: a machine base 100, a grinding machine 700 fixedly installed on the top of the machine base 100, a grinding tank 701 for cooperating operation fixedly installed on the machine base 100 below the grinding machine 700, a cleaning unit 800 fixedly installed on the machine base 100 on one side of the grinding tank 701, a material transfer unit 900 fixedly installed on the machine base 100 in front of the cleaning unit 800 and the grinding tank 701, a transmission unit 200 arranged at the end of the machine base 100, a mounting shell 300 fixedly connected to the drive end of the transmission unit 200, a conveying unit 600 assembled inside the mounting shell 300, a loading unit 400 fixedly connected to the top of the conveying unit 600, and a water removal component 500 fixedly connected to the side of the mounting shell 300.

[0054] In the above scheme:

[0055] Modular machine tool 100:

[0056] The top section integrates a grinding module 700, a cleaning module 800, a material transfer module 900, and a transmission module 200, with each module achieving coordinated control via an industrial bus.

[0057] The grinding module 700 includes a vibration-compensated grinder and a matching grinding tank 701, which is equipped with a pH sensor and a temperature closed-loop control system.

[0058] Multi-station conveyor system:

[0059] The transmission module 200 drives the mounting housing 300 to move along the X / Y / Z axes, and its interior is equipped with a dual-channel conveying unit 600.

[0060] An alternating linear drive structure is adopted, which includes two sets of carrier plates 603 synchronously controlled by a conveyor belt 611. The staggered lifting and lowering of the carrier plates is achieved through the wavy guide port 6021 of the guide plate 602.

[0061] The carrier plate 603 is equipped with an infrared sensor 624 and a limiting component 621, with a positioning accuracy of ±0.1mm;

[0062] Tilting loading unit 400:

[0063] The magnetic carrier 420 achieves ±180° rotation through the harmonic reduction motor 407. The array of magnetic strips 421 embedded in the carrier and the permanent magnet of the substrate loading component 430 constitute a programmable adsorption system.

[0064] Equipped with a dual positioning mechanism: the mechanical pin 413 and the Hall sensor work together to verify the vehicle's position;

[0065] Online Roller Press System 500:

[0066] The follow-up dewatering cotton roller 502 is equipped with a constant pressure control module, which adjusts the preload of the spring 504 through force feedback to ensure that the film pressing force is stable at 5-10N / cm².

[0067] Air flotation cleaning chamber 800:

[0068] The enclosed cleaning chamber 801 is equipped with a multi-degree-of-freedom cleaning robotic arm 806, which integrates a fan-shaped nozzle with an adjustable spray angle of 30-60° and a polyurethane squeegee 805.

[0069] The bottom air-bearing frame 807 provides a 0.5-2mm suspension gap, which is used in conjunction with the negative pressure edge positioning mechanism;

[0070] The mounting bracket 205 provides support and load-bearing for the working components, ensuring that the required conveying operations can be carried out.

[0071] The transmission unit 200 enables the equipment to make lateral adjustments to the entire conveying path, so that the conveying path can reach the required conveying station, improve the flexibility of the equipment during operation, and reduce the need for manual handling by personnel.

[0072] By using the conveying unit 600 inside the housing 300, the equipment can perform alternating conveying operations, avoiding the traditional back-and-forth intervals and ensuring the conveying process. During the conveying process, the conveying unit 600 can cooperate with the dewatering component 500 to roll and dewater the surface of the glass substrate inside the carrier 420, removing water stains from the surface of the substrate. Meanwhile, the water stains on the bottom of the substrate are absorbed by the water-absorbing pad inside the substrate loading component 430.

[0073] The loading unit 400 enables the equipment to simultaneously load and transport two sets of glass substrates. During loading, the loading surface can be switched by flipping, which also facilitates personnel retrieval, thereby increasing the equipment's conveying capacity.

[0074] The conveying unit 600 has two sets of support plates 601 fixedly connected to the bottom of the mounting shell 300. A guide plate 602 is fixedly connected to the mounting shell 300 between the support plates 601, and a guide opening 6021 is provided on the guide plate 602. A first guide plate 605 is slidably connected to the top of the support plate 601. A sliding seat 608 is slidably connected to the first guide plate 605 through the guide opening 6021. A second support plate 604 is fixedly connected to the top of the sliding seat 608. A third support plate 630 is slidably connected to the top of the mounting shell 300. A transmission component 610 connected to the first guide plate 605 and the third support plate 630 is connected to the inner wall of the mounting shell 300. A carrier plate 603 is fixedly connected to the top of both the third support plate 630 and the second support plate 604.

[0075] The loading unit 400 includes a positioning component 410 and a carrier 420. A fixing seat 406 is fixedly installed on one side of the top of the carrier plate 603. A mounting plate 401 is connected between the fixing seats 406. A rotating shaft 405 is connected to the inner side of the mounting plate 401. The carrier 420 is provided at the end of the rotating shaft 405. A substrate loading component 430 is adsorbed inside the carrier 420.

[0076] During daily operations:

[0077] The glass substrate is assembled in the substrate loading component 430, and then the substrate loading component 430 is accurately placed in the carrier 420. Then, the rotating shaft 405 is started to drive the carrier 420 to rotate, realizing the rotation and position switching of the carrier 420. Then, another set of substrate loading components 430 is placed in the carrier 420. By activating the transmission component 610, the transmission component 610 drives the second support plate 604 and the third support plate 630 simultaneously. At that time, the second support plate 604 and the third support plate 630 are driven by the driving force to move alternately in the mounting shell 300. During the alternation, the sliding seat 608 is guided by the guide port 6021, and during the alternation, the second support plate 604 is lowered by the action of the guide port 6021. In this way, the third support plate 630 can alternately offset with the second support plate 604. When it reaches the tail end, it can support and lift the second support plate 604.

[0078] like Figure 4 As shown, in order to enable the rotating shaft 405 to switch the carrier 420 in real time, a motor 407 is further fixedly connected to the fixed base 406, and the output end of the motor 407 is connected to the mounting plate 401. Magnetic strips 421 are embedded inside the carrier 420, and an adsorption strip corresponding to the magnetic strips 421 is fixedly provided on the substrate loading member 430. The carrier 420 is magnetically connected to the substrate loading member 430 through the magnetic strips 421. A telescopic cylinder 402 is fixedly connected to the outside of the mounting plate 401. The output end of the telescopic cylinder 402 is equipped with a gear rack 403 that is connected to the rotating shaft 405. A connecting strip 408 is installed at the end of the rotating shaft 405, and the connecting strip 408 is fixedly connected to the carrier 420.

[0079] The positioning component 410 includes a docking seat 411. The docking seat 411 is fixedly connected to one side of the top of the carrier plate 603. The docking block 412 is fixedly connected to one side of the bottom of the carrier 420, and the docking block 412 and the docking seat 411 are interlocked. An electric pin 413 is fixedly connected to the docking seat 411, and the electric pin 413 is used to position the docking block 412 in the docking seat 411. Arc-shaped guide strips are fixedly connected to the top of both sides of the carrier 420.

[0080] Specifically, after the glass substrate is assembled in the substrate loading component 430, the personnel can place it in the carrier 420. The adsorption component and the magnetic strip 421 on the inner side of the substrate loading component 430 are adsorbed and attached to the carrier 420. The carrier 420 is provided with a mounting groove for installing the magnetic strip 421. The substrate loading component 430 is provided with an adsorption block that can be embedded in the mounting groove. After docking, the two can be adsorbed to each other, and the accuracy of placing the substrate loading component 430 in the carrier 420 can be further guaranteed.

[0081] When switching the loaded glass substrate, the motor 407 can be started. The motor 407 drives the mounting plate 401 to flip up, and the components on the mounting plate 401 and the carrier 420 will also flip up synchronously. After it is raised to the maximum, the telescopic cylinder 402 is started. The telescopic cylinder 402 drives the rotating shaft 405 to rotate through the gear rack 403. At that time, the rotating shaft 405 can be used to drive the carrier 420 to rotate, thereby changing the loading surface of the carrier 420. Personnel place the assembled glass substrate into the carrier 420 according to the above steps.

[0082] Finally, the starting motor 407 uses the components to drive the carrier 420 to descend. When it descends to the bottom, the docking block 412 at the bottom of the carrier 420 can be inserted into the docking seat 411. After the docking is completed, the personnel can start the electric latch 413 to insert and position the docking block 412 in the docking seat 411.

[0083] During this process, when the carrier 420 is being transported, the arc-shaped guide bars on both sides of the carrier 420 will come into contact with the bottom of the water removal component 500. When the carrier 420 moves, the water removal component 500 will be guided to the top to roll and remove water stains from the surface of the glass substrate inside the carrier 420. Meanwhile, the water stains on the bottom of the substrate are absorbed by the water-absorbing pad in the substrate loading component 430.

[0084] like Figure 3 As shown, in order to enable the second support plate 604 to perform alternating operations, the four corners of the bottom of the second support plate 604 are further fixed with sliding rods 607, and the sliding rods 607 pass through the first guide plate 605. The first guide plate 605 and the first support plate 601 are slidably connected through sliding components 606.

[0085] Specifically, during this process, the sliding seat 608 is guided up and down by the guide port 6021, while the second support plate 604 can move up and down on the first guide plate 605 through the bottom slide rod 607. The first guide plate 605 slides on the top of the first support plate 601, and with the cooperation of the slide rod 607, the lifting and lowering adjustment of the first guide plate 605 is realized, thus enabling the first guide plate 605 to complete alternating operations.

[0086] like Figure 7 and Figure 8 As shown, the limiting component 620 further includes a limiting contact 621, a sleeve 622, and a sleeve rod 623. A connecting plate 626 is fixedly connected to one side of the bottom of the first guide plate 605. A sleeve 622 and a blocking member 625 are fixedly connected to both sides of the connecting plate 626, respectively. A sleeve rod 623 is fixedly connected to the inner wall of the mounting shell 300, and the sleeve rod 623 is fitted and connected to the sleeve 622. Two sets of limiting contacts 621 and infrared sensors 624 are fixedly connected to the bottom inside the mounting shell 300, and the two sets of limiting contacts 621 and infrared sensors 624 are located on both sides of the mounting shell 300, respectively. The limiting contact 621 abuts against the connecting plate 626, and the infrared sensor 624 cooperates with the blocking member 625.

[0087] Specifically, when the carrier 420 is conveying, the first guide plate 605 slides on the support plate 601, which drives the connecting plate 626 to move synchronously. At that time, the connecting plate 626 can drive the sleeve 622 to slide linearly on the sleeve rod 623, ensuring the stability of the carrier 420 during conveying. When the carrier 420 reaches the front and rear ends, the connecting plate 626 will be abutted by the limiting contact 621, and the blocking member 625 will also enter the infrared sensor 624 at this time. The infrared sensor 624 is blocked, and the electrical signal can be transmitted to the external control system, so that the subsequent conveying cycle can be carried out.

[0088] like Figure 3 As shown, in order to enable the carrier 420 to perform transport movement within the mounting housing 300, the transmission component 610 further includes a transmission wheel 613. Two sets of transmission wheels 613 are connected to the inner wall of the mounting housing 300, and the transmission wheels 613 are respectively located on both sides inside the mounting housing 300. A transmission belt 611 for transmission is fitted on the transmission wheel 613. The top and bottom of the transmission belt 611 are fixedly connected to the connector 612 that connects to the first guide plate 605 and the support plate 630.

[0089] Specifically, during this period, the motor on the mounting housing 300 is started, and the output end of the motor drives the transmission wheel 613 to rotate. Under the transmission of the transmission wheel 613, the transmission belt 611 is driven. At that time, the transmission belt 611 can drive the first guide plate 605 and the support plate 630 on each of them to move alternately in opposite directions through the connector 612.

[0090] The transmission component 610 serves as the power source, enabling the equipment to drive the internal components.

[0091] Furthermore, the transmission unit 200 includes a mounting bracket 205 and a mounting groove 204. The mounting bracket 205 is installed at the end of the machine base 100. The mounting groove 204 is fixedly installed on the top of the mounting bracket 205. An electric lead screw 201 is installed inside the mounting groove 204. A guide seat 202 is fitted on the electric lead screw 201 and is slidably connected to the mounting groove 204. An electric turntable 203 is fixedly installed on the top of the guide seat 202 and is fixedly connected to the bottom of the mounting shell 300.

[0092] Specifically, during this period, when the conveying station of the equipment needs to be adjusted, the personnel can start the electric screw 201. The electric screw 201 drives the guide seat 202, causing the guide seat 202 to move linearly within the mounting groove 204, thereby realizing real-time adjustment of the mounting shell 300 station.

[0093] Furthermore, during operation, personnel can use the electric turntable 203 to adjust the conveying position of the mounting shell 300 in real time, thus completing multi-level adjustments of the workstation.

[0094] Furthermore, the dewatering assembly 500 includes a support frame 501. The support frame 501 is fixedly installed on the outside of the mounting housing 300. Two sets of guide rods 505 are installed at the top of the support frame 501, and springs 504 are fitted on the guide rods 505. A roller seat 503 is installed at the bottom of the guide rods 505, and a dewatering cotton roller 502 is installed inside the roller seat 503. The dewatering cotton roller 502 is rotatably connected to the roller seat 503.

[0095] Specifically, when the carrier 420 is conveyed, the arc-shaped guide bars on both sides of the carrier 420 will abut against the bottom of the dewatering cotton roller 502. When the carrier 420 moves, the dewatering cotton roller 502 will roll onto the upper surface of the carrier 420 under the guidance. The dewatering cotton roller is made of cotton material with water absorption effect.

[0096] Furthermore, the cleaning unit 800 includes a cleaning chamber 801, which is fixedly installed on the top of the machine base 100. The cleaning chamber 801 is provided with a guide port 802. An electric lead screw 803 is installed on the top of the cleaning chamber 801. An installation block 804 is installed on the drive end of the electric lead screw 803. Two sets of cleaning rods 806 are fixedly installed on the bottom of the installation block 804. A scraper 805 is fixedly installed on the side of the cleaning rods 806. An air float 807 is fixedly installed on the bottom of the cleaning chamber 801.

[0097] During this process, the transfer unit 900 transfers the ground substrate to the cleaning chamber 801 for cleaning. The transfer unit 900 switches the orientation of the substrate from the original horizontal state to the vertical state and places it in the air float 807. The air float 807 is in the activated state, causing the glass substrate to enter the air float state. At this time, the electric lead screw 803 is activated, which drives the mounting block 804, causing the mounting block 804 to move linearly with its two sets of cleaning rods 806 and squeegee 805. During this process, the cleaning rods 806 clean the glass substrate through the inner nozzles, and at the same time, the squeegee 805 at the rear scrapes water off the cleaned substrate surface. The cleaning rods 806 need to be cleaned through an external water pipe.

[0098] Furthermore, the material transfer unit 900 includes an electric track 901. The electric track 901 is fixedly installed on the top of the machine base 100. A vertical plate 902 is fixedly installed on the sliding part of the electric track 901. A fixed seat 904 is fixedly installed on the side of the vertical plate 902. A telescopic cylinder 903 is fixedly installed on the top of the fixed seat 904. The output end of the telescopic cylinder 903 passes through the fixed seat 904 and is connected to a right-angle plate 905. An electric turntable 907 is fixedly installed on the outside of the right-angle plate 905. A gripper 906 is fixedly installed on the rotating end of the electric turntable 907.

[0099] During the process, after the substrate is ground, it needs to be transferred through the transfer unit 900. After the substrate is ground, the bottom right-angle plate 905 can be lowered by activating the telescopic cylinder 903, causing the gripper 906 to enter the gripping state. The gripper 906 is pneumatically driven and completes the gripping and extraction of the substrate, and then lifts it. The gripped substrate moves linearly through the movement of the electric track 901. At that time, the gripper 906 and the gripped substrate enter the cleaning chamber 801 through the guide port 802. In order to ensure that the substrate can be cleaned, the gripped substrate needs to be switched from the horizontal to the vertical state by the electric turntable 907, so that the substrate can be placed in the air float 807. After the cleaning is completed, the substrate can be gripped again by the gripper and the position can be changed. The purpose is to ensure that the substrate is continuously transported to the loading unit 400 and placed in the carrier 420 for transport.
