Description

Technical Field

[0002] In contemporary industrial production and high-end manufacturing, glass-ceramic panels, thanks to their excellent mechanical strength, high-temperature resistance, chemical stability, and transparent appearance, are widely used in a variety of applications, including home appliance panels and precision instrument operating panels. As market demand for glass-ceramic panels continues to rise, and with increasingly stringent requirements for surface flatness, smoothness, and other quality indicators, efficient and precise polishing processes have become a key factor affecting product quality and production efficiency.

[0003] Most of the current mainstream microcrystalline glass panel polishing equipment adopts a single-station design and can only polish one microcrystalline glass panel at a time.

[0004] During the specific processing process, when a panel is polished, it needs to be removed from the polishing station by humans or a special robotic arm, and then repositioned and installed with a new panel to be polished. During the entire process, the polishing equipment is in a shutdown waiting state, which not only leads to a low proportion of the equipment's effective operating time, greatly limiting the improvement of overall production efficiency, but also increases labor costs or the complexity of equipment control due to frequent loading and unloading operations, making it difficult to meet the actual needs of large-scale, high-precision production.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] In the description of this application, it should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship. Technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, the technologies, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0021] Example 1: like Figures 1 to 7 As shown, the present invention discloses a glass-ceramic panel grinding line, comprising a flat grinding unit 10 and a polishing unit 20 sequentially arranged along the processing direction of the grinding line (i.e., the length direction of the line); Among them, the flat grinding unit 10 includes: The upper end of the polishing device 1 is provided with a plurality of lifting polishing units 100 spaced apart along the length direction of the polishing device 1; The cleaning device 2 is located downstream of the polishing device 1, and a transfer device 3 is provided between the two to transfer the glass-ceramic panel into the cleaning device 2; Among them, the polishing unit 20 is provided with a cleaning device 2, and a grinding and polishing device 2 and a transfer device 2 having the same structure as the grinding and polishing device 1 and the transfer device 3.

[0022] By adopting the above technical solution, through the continuous setting of the flat grinding unit and the polishing unit, the multi-unit design of the grinding and polishing device and the transfer device, the simultaneous processing of multiple panels and the seamless connection of each link are achieved, which reduces downtime and dependence on manual labor, reduces costs, can meet the needs of large-scale, high-precision mass production, and provide reliable support for industrialized production.

[0023] Example 2: This embodiment provides a microcrystalline glass panel polishing production line, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0024] Furthermore, the grinding and polishing device 1 includes: The grinding and polishing machine body 101 is installed on the ground; The grinding chamber 102 is provided in the middle of the grinding and polishing machine body 101 along the length direction of the grinding and polishing machine body 101, and both ends of the grinding chamber 102 in the length direction and the width direction are open; A plurality of partitions 103 are connected and fixed to the upper end of the polishing chamber 102 and are arranged at intervals along the length of the polishing chamber 102 to divide the polishing chamber 102 into a plurality of polishing areas. A gap is provided between the lower end of the partition 103 and the bottom of the polishing chamber 102. The plurality of grinding areas correspond to the plurality of lifting grinding and polishing units 100 . The lifting grinding and polishing units 100 are connected and fixed to the upper end of the grinding and polishing machine body 101 , and at least partially penetrate the grinding and polishing machine body 101 and extend into the grinding area.

[0025] In the above technical solution, during the polishing operation, the glass-ceramic panel continuously moves and passes through each polishing zone, contacting the lifting and polishing units of each polishing zone in turn. Due to the gap between the lower end of the partition and the bottom of the polishing chamber, the movement of the panel is not hindered. By adopting the above technical solution, a number of partitions divide the grinding chamber into multiple independent grinding areas, and each of them corresponds to the lifting grinding and polishing unit. This can effectively avoid mutual interference between different grinding areas and reduce the impact of debris and abrasive splashing generated during the grinding process on panels in other areas. At the same time, it is convenient to independently control each lifting grinding and polishing unit according to the different grinding requirements of different batches of panels, so as to meet the grinding accuracy requirements of different batches of panels. At the same time, there is no need to reserve downtime for the polishing process of a single panel. After each panel enters the polishing chamber, the processing from the first polishing area to the last polishing area is completely continuous, which greatly shortens the total polishing cycle of a single panel. More panels can be processed in a unit time, significantly improving overall production capacity.

[0026] Example 3: This embodiment provides a microcrystalline glass panel polishing production line, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0027] Furthermore, the grinding and polishing device 1 also includes: There are two transmission rollers 104, which are rotatably connected to the two ends of the grinding and polishing machine body 101 in the length direction; The conveyor belt 105 is disposed between the two driving rollers 104 and at least partially passes through the bottom of the polishing chamber 102; The carriage 106 is disposed on the surface of the conveyor belt 105. The carriage 106 is rectangular and has a plurality of limit blocks on the four edges of the upper end of the carriage 106. The limit blocks form a receiving area for loading the micro-ceramic glass panel. The conveyor belt 105 passing through the polishing chamber 102 is located below the partition 103 .

[0028] In the above technical solution, after the accommodating cavity is loaded with the glass-ceramic panel, the level of the limit block is lower than the level of the panel, thereby avoiding interference between the limit block and the grinding disc; In the above technical solution, a "door"-shaped alignment plate is provided above the conveyor belt at the right end of the grinding and polishing machine body, i.e., the feeding end. The lower end of the alignment plate is fixedly connected to the grinding and polishing machine body. Guide plates are fixedly installed on both sides of the lower end of the alignment plate. The two guide plates form a V-shaped guide structure. A pressure wheel is fixedly connected to the middle of the alignment plate, so that when the carriage loaded with the micro-ceramic glass panel passes through the alignment plate, the carriage guide can be calibrated, so that the carriage will not be in an offset state when entering the grinding area. At the same time, the pressure wheel will lightly press on the surface of the micro-ceramic glass panel to ensure that the panel remains flat when entering the grinding area. By adopting the above technical solution, the conveyor belt supported by two drive rollers forms a stable conveying carrier. The rotation of the drive rollers drives the conveyor belt to run at a uniform speed, providing continuous and smooth moving power for the carriage and the microcrystalline glass panel above it.

[0029] Example 4: This embodiment provides a microcrystalline glass panel polishing production line, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0030] Furthermore, the lower edge of the upper end of the grinding and polishing body 101 is provided with a receiving groove 107 along its length direction. The receiving groove 107 is located above the grinding area. The lifting grinding and polishing unit 100 includes: The driving motor 108 is connected and fixed to the upper edge of the upper end of the grinding and polishing machine body 101; There are two lifting cylinders 109, which are connected and fixed to both sides of the notch of the receiving slot 107 through a cylinder seat. The lifting cylinders 109 are vertically arranged, and their fixed ends are connected and fixed to the cylinder seat; A support plate 110 is connected and fixed between the output ends of the two lifting cylinders 109. A support sleeve 111 extending toward the receiving groove 107 is connected and fixed to the middle of the support plate 110. The rotating shaft 112 is rotatably connected to the lower end of the supporting sleeve 111. The bottom of the receiving groove 107 is provided with a through hole connected to the grinding area. The lower end of the rotating shaft 112 extends through the through hole into the grinding area to connect and fix the grinding disc. The driven wheel 113 is located in the receiving groove 107 and is sleeved on the outside of the rotating shaft 112; Among them, a second accommodating groove 114 is opened on the side of the accommodating groove 107 adjacent to the drive motor 108. The output end of the drive motor passes through the grinding and polishing machine body 101 and extends into the second accommodating groove 114 and is connected and fixed with a driving wheel 115. The driving wheel 115 is connected to the driven wheel 113 through a toothed belt transmission, and the driven wheel 113 is connected to the rotating shaft 112 through a shaft sleeve 116.

[0031] In the above technical solution, a main control panel and several lifting and polishing unit control panels are installed on the upper edge of the front end of the grinding and polishing machine body. The lifting and polishing unit control panels correspond to the lifting and polishing units one by one to achieve precise control and flexible operation of the entire grinding and polishing device 1. Similarly, the grinding and polishing device 2 is also equipped with the same control panel. In the above technical solution, the grinding disc of the lifting grinding and polishing unit of the grinding and polishing device 1 is a flat grinding disc, and the abrasive particle size is gradually refined from the first grinding zone to the last grinding zone. The grinding disc of the lifting grinding and polishing unit of the grinding and polishing device 2 is a polishing disc, and the abrasive particle size is gradually refined from the first grinding zone to the last grinding zone, thereby improving production efficiency while ensuring the consistency and high quality of the product surface quality. By adopting the above technical solution, the arrangement of the receiving tank 1 and the receiving tank 2 provides an independent installation space for the lifting grinding and polishing unit, which is not easily affected by external interference. The two vertically arranged lifting cylinders are fixed to the two sides of the notch of the receiving tank 1 through the cylinder seat, and their output ends are connected to the support plate together to form a symmetrical support structure, which can drive the support plate and the rotating shaft and grinding disc below to rise and fall smoothly. The dual-cylinder drive method mentioned above can effectively avoid the tilting or jamming that may occur in a single-cylinder drive, ensuring that the grinding disc always remains horizontal during the up and down movement, ensuring a stable contact angle with the micro-ceramic panel. At the same time, the dual-cylinder drive can stably adjust the contact pressure of the grinding disc on the micro-ceramic panel to meet different grinding needs. The drive motor, through the active pulley, toothed belt, and driven pulley, forms a transmission system that features precise transmission ratios and smooth operation. The toothed belt effectively prevents slippage, ensuring efficient transmission of the drive motor's power to the rotating shaft. This maintains a stable grinding disc speed and reduces uneven grinding results caused by speed fluctuations.

[0032] Example 5: This embodiment provides a microcrystalline glass panel polishing production line, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0033] Furthermore, the lifting and polishing unit also includes: A fixing plate 117 is connected and fixed to the upper opening of the through hole; The second support sleeve 118 is sleeved on the outside of the rotating shaft 112 and located in the through hole, and its upper end is connected and fixed to the fixing plate 117; The shaft sleeve 116 is sleeved on the outside of the rotating shaft 112 and is located inside the second support sleeve 118. The radial outer side of the shaft sleeve 116 is rotatably connected to the second support sleeve 118 through a plurality of rotating bearings. Among them, the rotating shaft 112 is provided with a spline shaft section 1 connected to the sleeve 116 through a spline. The spline shaft section 1 can slide axially relative to the sleeve 116. The lower end of the driven wheel 113 is fixedly connected to the upper end of the sleeve 116. The lower end cover of the support sleeve 118 is provided with a cover for the rotating shaft 112 to extend.

[0034] In the above technical solution, the shaft sleeve and the rotating bearing are interference fit, and the lower end of the driven shaft at least partially extends into the shaft sleeve and is fixed to the shaft sleeve by a pin; By adopting the above technical solution, through the arrangement of the fixed plate, the second support sleeve, the shaft sleeve and the spline shaft segment, the fixed plate provides stable support for the second support sleeve, and cooperates with the rotating bearing to form a multi-layer radial support for the rotating shaft, thereby preventing the rotating shaft from shaking and swaying, and ensuring the accurate rotation posture of the grinding disc; The spline shaft section of the rotating shaft is connected to the spline groove of the sleeve, which realizes the independent rotation and lifting motion without interference, ensuring the stability of power transmission; The cover design can not only effectively prevent the debris and dust generated during the grinding process from entering the interior of the support sleeve 2, avoiding wear or blockage of precision components such as rotating bearings and spline connections, but also provide auxiliary support for the support sleeve 2, further enhancing the structural stability of the support sleeve 2.

[0035] Example 6: This embodiment provides a microcrystalline glass panel polishing production line, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0036] Furthermore, the grinding and polishing machine body 101 further includes: Drain troughs 119 are respectively provided at the lower edges of the front and rear sides of the polishing machine body 101; A plurality of cover plates 120 are provided at both ends of the grinding chamber 102 in the width direction to seal the grinding chamber 102; There is a gap between the cover plate 120 and the lower edge of the polishing chamber 102 , and a brush is fixedly connected to the lower end of the cover plate 120 .

[0037] In the above technical solution, each cover plate corresponds to a grinding area, and a magnetic strip is fixed to the inner upper edge of the grinding chamber. The cover plate is magnetically adsorbed on the magnetic strip, making it easy to disassemble and replace the grinding disc by disassembling the cover plate; By adopting the above technical solution, the waste liquid generated during the grinding process flows into the drainage trough through the grinding chamber. The cover plate can prevent the waste liquid and dust from splashing. The setting of the brush allows the waste liquid to flow out through the gaps in the brush while blocking the rapidly splashing waste liquid and dust.

[0038] Example 7: This embodiment provides a microcrystalline glass panel polishing production line, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0039] Furthermore, it also includes: The rotary conveyor frame 121 is installed on the ground and is located at the rear side of the grinding and polishing machine body 101. The rotary conveyor frame 121 is equipped with a rotary conveyor belt. There are two sets of corner conveyor racks 122. The two sets of corner conveyor racks 122 are installed on the ground and are located on both sides of the rotary conveyor rack 121 to form a "door"-shaped structure with the rotary conveyor rack 121. Corner conveyor belts are installed on the corner conveyor racks 122. A lifting roller frame is installed on the inner side of the corner conveyor frame 122; There are two auxiliary conveyor racks, which are installed on the ground and located on both sides of the grinding and polishing machine body 101 in the length direction. The two auxiliary conveyor racks are adjacent to the two corner conveyor racks 122 respectively, and auxiliary conveyor belts are installed on the auxiliary conveyor racks.

[0040] In the above technical solution, the two auxiliary conveyor racks correspond one to one with the two groups of corner conveyor racks, and each group of corner conveyor racks includes a transverse corner conveyor rack located in the length direction of the rotary conveyor rack, and a longitudinal corner conveyor rack located in front of the transverse corner conveyor rack and adjacent to its corresponding auxiliary conveyor rack; In the above technical solution, the second grinding and polishing device also has the same rotary conveyor frame, corner conveyor frame and auxiliary conveyor frame as above; In the above technical solution, the lifting roller frame includes a roller frame body slidably mounted in the auxiliary conveyor frame, and a plurality of support rollers connected by a synchronous belt are rotatably connected to the roller frame body. The roller frame body is driven by pneumatic or hydraulic pressure to drive the support rollers to rise or fall, so as to lift the carriage; By adopting the above technical solution, through the coordinated arrangement of the corner conveyor rack, the rotary conveyor rack and the auxiliary conveyor rack, the slide of the polishing device 1 is first moved to the corner conveyor rack and then the microcrystalline glass panel is transported to the next workstation through the transfer device 1. Then the empty slide follows the auxiliary conveyor rack into the rotary conveyor rack for transportation, and then returns to the right end of the polishing device 1 to load a new panel. This cycle is repeated without the need for manual handling of the slide, saving time and effort.

[0041] Example 8: This embodiment provides a microcrystalline glass panel polishing production line, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0042] Furthermore, the transfer device 3 includes: The transfer body 300 is located above the corner conveyor frame 122 adjacent to the output end of the grinding and polishing body 101. The four corners of the lower end of the transfer body 300 are connected to support feet that extend toward the ground. The transfer head 301 is slidably mounted on the lower end of the transfer body 300; The lifting head 302 is slidably mounted on one side of the transfer head 301. The lifting head 302 can slide up and down relative to the transfer head 301. The transfer plate 303 is connected and fixed to the lower end of the lift head 302. The lower end of the transfer plate 303 is provided with a plurality of suction cups for sucking the glass-ceramic panel on the carriage 106. Among them, an air injection pipe 304 extending upward from the corner conveying frame 122 is connected and fixed to one side of the corner conveying frame 122 below the transfer body 300 .

[0043] In the above technical solution, a screw for driving the transfer head to move is installed in the transfer body, and the transfer head is connected to the screw through a threaded slider; By adopting the above technical solution, when the auxiliary conveyor with the micro-ceramic glass panel moves to the bottom of the corner conveyor, the lifting head starts, driving the transfer plate to descend, so that the vacuum suction cup is attached to the panel and fixed, then the lifting head resets, the transfer head moves, driving the panel to move horizontally to the input end of the cleaning device, then the lifting head descends, releases the vacuum suction cup and resets, completing the transfer of the panel, replacing the traditional mechanical clamping method, which can not only ensure that the panel will not fall off during the transfer process, but also avoid damage to the panel caused by excessive clamping force; During sanding, water may seep into the space between the panel and the drag plate, making it difficult for the panel to separate from the drag plate. By setting up an air jet, compressed air can be sprayed into the gap between the panel and the drag plate before the transfer action to blow away the water and facilitate the separation of the panel.

[0044] Example 9: This embodiment provides a microcrystalline glass panel polishing production line, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0045] Furthermore, the cleaning device 2 includes: A cleaning body 200 is installed on the ground, and at least a portion of the cleaning body 200 extends below the transfer device 3; A plurality of conveying rollers 201 are connected to both sides of the upper end of the cleaning body 200 and are rotatable along the length direction of the cleaning body 200; A cleaning cover 202 is provided in the middle of the cleaning body 200; The cleaning cover 202 includes a cleaning area and a drying area arranged along its length, and a plurality of water spray pipes are provided above the cleaning area; The cleaning area also includes: Several traction roller groups are arranged side by side along the length of the cleaning area and are rotatably connected to the bottom of the cleaning area.

Each brush roller group includes two upper and lower brush rollers connected by gear transmission. Two traction roller groups are arranged between two adjacent brush roller groups. Among them, a water baffle is provided in the middle of the cleaning cover 202 to separate the cleaning area and the drying area, and an air inlet pipe and an air outlet pipe connected to the drying area are embedded on one side of the drying area.

[0046] By adopting the above technical solution, the water spray pipes in the cleaning area can spray clean water or cleaning liquid onto the upper and lower surfaces of the panel. In conjunction with the upper and lower brush rollers connected by gear transmission, the panel can be scrubbed in all directions. The upper and lower settings of the brush rollers ensure that both the front and back of the panel are thoroughly cleaned. A water baffle effectively separates the cleaning and drying areas, preventing moisture from entering the drying area and affecting the drying process. The drying area's air inlet duct allows hot air to enter, while the air outlet duct removes moisture, creating a good air circulation that quickly removes moisture from the panel surface and achieves efficient panel drying.

[0047] Example 10: This embodiment provides a microcrystalline glass panel polishing production line, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0048] Furthermore, the second cleaning device includes a second cleaning body and a second cleaning cover having the same structure as the first cleaning body 200 and the first cleaning cover 202, and the second cleaning body is installed on the ground; The second transfer device is located downstream of the second grinding and polishing device, the second cleaning body is located downstream of the second transfer device, and the second cleaning device further includes: The water washing tank 400 is installed on the ground and is located between the second cleaning body and the second transfer device. The water washing tank 400 at least partially extends under the second cleaning body. A plurality of conveying rollers 2 are connected to the water washing tank 400 and rotate along the length direction of the water washing tank 400; By adopting the above technical solution, the second cleaning body and the second cleaning cover adopt the same structure as the first cleaning body and the first cleaning cover, and are also equipped with clearly divided cleaning and drying areas, as well as cleaning components such as a water spray pipe, a traction roller group, and a brush roller group, ensuring that the panel can be deeply cleaned to the same standard as after flat grinding after being polished by the second grinding and polishing device; The water washing tank is set up to pre-clean the panel, which avoids a large amount of impurities from directly contacting the brush rollers in the cleaning area. If the panel carries too many impurities into the brush roller group, it may cause the impurities to accumulate on the brush, and then cause secondary contamination or scratches to the panel during brushing.
