Description

Technical Field

[0001] This invention relates to the field of microcrystalline glass technology, and in particular to a microcrystalline glass panel polishing production line. Background Technology

[0002] In contemporary industrial production and high-end manufacturing, microcrystalline glass panels are widely used in various applications such as home appliance panels and precision instrument control panels due to their excellent mechanical strength, high temperature resistance, chemical stability, and transparent appearance. As market demand for microcrystalline glass panels continues to rise, and the requirements for quality indicators such as surface flatness and smoothness become increasingly stringent, efficient and precise grinding and processing have become key factors affecting product quality and production efficiency.

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

[0004] In the actual processing, after a panel is polished, it needs to be removed from the polishing station manually or by a special robotic arm. Then, a new panel to be polished is repositioned and installed. Throughout the process, the polishing equipment is in a standby state, which not only results in a low percentage of effective working time for the equipment, greatly limiting the improvement of overall production efficiency, but also increases labor costs or equipment control complexity due to frequent loading and unloading operations, making it difficult to meet the actual needs of large-scale, high-precision production. Summary of the Invention

[0071] 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.

[0072] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is 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 to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0073] Example 1:

[0074] like Figures 1 to 7 As shown, the present invention discloses a microcrystalline glass panel grinding production line, including a flat grinding unit 10 and a polishing unit 20 arranged sequentially along the processing direction of the grinding production line (i.e., the length direction of the production line);

[0075] The surface mill unit 10 includes:

[0076] The grinding and polishing device 1 has several lifting grinding and polishing units 100 arranged at intervals along the length of the grinding and polishing device 1 at its upper end.

[0077] Cleaning device 2 is located downstream of polishing device 1, and a transfer device 3 is provided between the two to transfer the microcrystalline glass panel into cleaning device 2.

[0078] Among them, the polishing unit 20 is equipped with a cleaning device 2, as well as a polishing device 2 and a transfer device 2 with the same structure as the polishing device 1 and the transfer device 3.

[0079] By adopting the above technical solutions, through the continuous setup of the flat grinding unit and the polishing unit, the multi-unit design of the grinding and polishing device, and the transfer device, the synchronous processing of multiple panels and the seamless connection of each link are realized, reducing downtime and reliance on manual labor, lowering costs, meeting the needs of large-scale, high-precision mass production, and providing reliable support for industrial production.

[0080] Example 2:

[0081] 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.

[0082] Furthermore, the polishing device 1 includes:

[0083] The grinding and polishing machine body 101 is installed on the ground;

[0084] The grinding chamber 102 is located 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 and width directions are open.

[0085] Several partitions 103 are connected and fixed to the upper end of the grinding chamber 102 and are arranged at intervals along the length of the grinding chamber 102 to divide the grinding chamber 102 into several grinding areas. A gap is provided between the lower end of the partition 103 and the bottom of the grinding chamber 102.

[0086] Among them, several grinding areas correspond one-to-one with several 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.

[0087] In the above technical solution, during the polishing operation, the microcrystalline glass panel moves continuously and passes through each polishing area, contacting the lifting and polishing unit of each polishing area in turn. Since there is a gap between the lower end of the partition and the bottom of the polishing chamber, it will not hinder the movement of the panel.

[0088] By adopting the above technical solution, several partitions divide the grinding chamber into multiple independent grinding zones, which correspond one-to-one with the lifting and polishing units. This can effectively avoid mutual interference between different grinding zones, reduce the impact of debris and abrasive splashes generated during the grinding process on other areas of the panel, and facilitate independent adjustment of each lifting 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.

[0089] Meanwhile, 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 zone to the last polishing zone is continuous, which greatly shortens the total polishing cycle of a single panel. More panels can be processed per unit time, significantly improving the overall production capacity.

[0090] Example 3:

[0091] 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.

[0092] Furthermore, the polishing device 1 also includes:

[0093] Two drive rollers 104 are provided, and the two drive rollers 104 are respectively rotatably connected to both ends of the grinding and polishing machine body 101 along the length direction;

[0094] The conveyor belt 105 is fitted between the two drive rollers 104 and at least partially passes through the lower part of the grinding chamber 102;

[0095] A slide plate 106 is disposed on the surface of the conveyor belt 105. The slide plate 106 is rectangular, and several limiting blocks are provided on the four edges of the upper end of the slide plate 106. The several limiting blocks form a receiving area for loading the microcrystalline glass panel.

[0096] The conveyor belt 105 passing through the grinding chamber 102 is located below the partition 103.

[0097] In the above technical solution, after the microcrystalline glass panel is loaded into the receiving cavity, the horizontal height of its limiting block is lower than the horizontal height of the panel to avoid interference between the limiting block and the grinding disc.

[0098] 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 connected and fixed 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 roller is connected and fixed in the middle of the alignment plate, so that when the slide carrying the microcrystalline glass panel passes through the alignment plate, the slide can be guided and aligned, so that the slide will not enter the grinding area in a deviated state. At the same time, the pressure roller will lightly press on the surface of the microcrystalline glass panel to ensure that the panel remains flat when entering the grinding area.

[0099] By adopting the above technical solution, the conveyor belt supported by the two drive rollers forms a stable conveying carrier. The rotation of the drive rollers drives the conveyor belt to run at a constant speed, providing continuous and stable moving power for the slide and the microcrystalline glass panel on it.

[0100] Example 4:

[0101] 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.

[0102] Furthermore, the upper lower edge of the polishing machine body 101 is provided with a receiving groove 107 extending along its length. The receiving groove 107 is located above the polishing area. The lifting polishing unit 100 includes:

[0103] The drive motor 108 is connected and fixed to the upper edge of the upper end of the grinding and polishing machine body 101;

[0104] There are two lifting cylinders 109. The two lifting cylinders 109 are connected and fixed on both sides of the opening of the receiving groove 107 through cylinder seats. The lifting cylinders 109 are arranged vertically, and their fixed ends are connected and fixed to the cylinder seats.

[0105] A support plate 110 is fixedly connected between the output ends of two lifting cylinders 109. A support sleeve 111 extending toward the receiving groove 107 is fixedly connected to the middle of the support plate 110.

[0106] The rotating shaft 112 is rotatably connected to the lower end of the support sleeve 111. The bottom of the receiving groove 107 has a through hole for connecting the grinding area. The lower end of the rotating shaft 112 extends through the through hole into the grinding area and is connected and fixed to the grinding disc.

[0107] Driven wheel 113 is located in receiving groove 107 and sleeved on the outside of rotating shaft 112;

[0108] Among them, the receiving groove 107 is adjacent to the side of the drive motor 108 and the receiving groove 114 is provided. The output end of the drive motor passes through the polishing machine body 101, extends into the receiving groove 114 and is connected and fixed to the drive wheel 115. The drive wheel 115 and the driven wheel 113 are connected by toothed belt drive. The driven wheel 113 is connected to the rotating shaft 112 by bushing 116 drive.

[0109] In the above technical solution, a main control panel and several lifting grinding and polishing unit control panels are installed on the upper edge of the front end of the grinding and polishing machine body. The lifting grinding and polishing unit control panels correspond one-to-one with the lifting grinding and polishing units to achieve precise control and flexible operation of the entire grinding and polishing device one. Similarly, the grinding and polishing device two is also equipped with the same control panel.

[0110] In the above technical solution, the grinding disc of the lifting grinding and polishing unit of the first grinding and polishing device is a flat grinding disc, which gradually refines the abrasive particle size from the first grinding zone to the last grinding zone. The grinding disc of the lifting grinding and polishing unit of the second grinding and polishing device is a polishing disc, which gradually refines the abrasive particle size from the first grinding zone to the last grinding zone. This improves production efficiency while ensuring the consistency and high quality of the product surface.

[0111] By adopting the above technical solution, the arrangement of the first and second receiving tanks provides an independent installation space for the lifting and polishing unit, which is not easily affected by external interference. The two vertically arranged lifting cylinders are fixed to both sides of the opening of the first receiving tank through cylinder seats, and their output ends are connected to the support plate to form a symmetrical support structure, which can drive the support plate and the rotating shaft and grinding disc below to lift smoothly.

[0112] The aforementioned dual-cylinder drive method can effectively avoid tilting or jamming that may occur with single-cylinder drive, ensuring that the grinding disc remains horizontal during its up-and-down movement, and ensuring a stable contact angle with the microcrystalline glass panel. At the same time, the dual-cylinder drive can stably adjust the contact pressure of the grinding disc on the microcrystalline glass panel to meet different grinding needs.

[0113] The drive motor, through a transmission system formed by the driving pulley, toothed belt, and driven pulley, features precise transmission ratio and smooth operation. The toothed belt effectively prevents slippage, ensuring efficient power transmission from the drive motor to the shaft, resulting in a stable rotational speed for the grinding disc and reducing uneven grinding effects caused by speed fluctuations.

[0114] Example 5:

[0115] 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.

[0116] Furthermore, the lifting and polishing unit also includes:

[0117] Fixing plate 117 is connected and fixed to the upper opening of the through hole;

[0118] Support sleeve 2 118 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.

[0119] Among them, the bushing 116 is sleeved on the outside of the rotating shaft 112 and located inside the second support sleeve 118. The radial outer side of the bushing 116 is rotatably connected to the second support sleeve 118 through several rotating bearings.

[0120] The rotating shaft 112 is provided with a spline shaft section 1 that is connected to the bushing 116 via a spline. The spline shaft section 1 can slide relative to the bushing 116 along the axial direction. The lower end of the driven wheel 113 is connected and fixed to the upper end of the bushing 116. The lower end of the support sleeve 118 is covered with a cover for the rotating shaft 112 to extend out.

[0121] In the above technical solution, the bushing is interference-fitted with the rotating bearing, and the lower end of the driven shaft extends at least partially into the bushing and is fixed to the bushing by a pin connection.

[0122] By adopting the above technical solution, through the setting of the fixed plate, the second support sleeve, the bushing and the spline shaft section, the fixed plate provides stable support for the second support sleeve, and together with the rotating bearing, forms a multi-layer radial support for the rotating shaft, avoiding the shaking and wobbling of the rotating shaft and ensuring the accurate rotation posture of the grinding disc;

[0123] The splined shaft section of the rotating shaft is connected to the splined groove of the bushing, so that the rotation and lifting movements are independent and do not interfere with each other, ensuring the stability of power transmission.

[0124] The cover design not only effectively prevents debris and dust generated during the grinding process from entering the interior of the second support sleeve, avoiding wear or blockage of precision components such as rotating bearings and spline connections, but also provides auxiliary support for the second support sleeve, further enhancing its structural stability.

[0125] Example 6:

[0126] 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.

[0127] Furthermore, the grinding and polishing machine body 101 also includes:

[0128] Drainage troughs 119 are respectively located on the lower edges of the front and rear sides of the grinding and polishing machine body 101;

[0129] Several cover plates 120 are placed on both ends of the grinding chamber 102 in the width direction to close the grinding chamber 102;

[0130] The cover plate 120 has a gap with the lower edge of the grinding chamber 102, and a brush is fixedly connected to the lower end of the cover plate 120.

[0131] In the above technical solution, each cover plate corresponds to a grinding area. A magnetic strip is fixed to the inner upper edge of the grinding chamber. The cover plate is magnetically attached to the magnetic strip, which makes it easy to disassemble and replace the grinding disc.

[0132] By adopting the above technical solution, the waste liquid generated during the grinding process flows into the drain tank through the grinding chamber. The cover plate can prevent waste liquid and dust from splashing. The brush allows the waste liquid to flow out through the gaps in the brush, while blocking the rapidly splashing waste liquid and dust.

[0133] Example 7:

[0134] 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.

[0135] Furthermore, it also includes:

[0136] A rotary conveyor frame 121 is installed on the ground and located behind the grinding and polishing machine body 101. A rotary conveyor belt is installed on the rotary conveyor frame 121.

[0137] The corner conveyor frame 122 is provided in two sets. The two sets of corner conveyor frames 122 are installed on the ground and are located on both sides of the rotary conveyor frame 121, forming a "gate" shaped structure with the rotary conveyor frame 121. A corner conveyor belt is installed on the corner conveyor frame 122.

[0138] The lifting roller frame is installed inside the corner conveyor frame 122;

[0139] There are two auxiliary conveyor frames. The two auxiliary conveyor frames are installed on the ground and located on both sides of the length of the grinding and polishing machine body 101. The two auxiliary conveyor frames are adjacent to two corner conveyor frames 122 respectively. The auxiliary conveyor frames are equipped with auxiliary conveyor belts.

[0140] In the above technical solution, the two auxiliary conveyor frames correspond one-to-one with the two sets of corner conveyor frames. Each set of corner conveyor frames includes a transverse corner conveyor frame located in the length direction of the rotary conveyor frame, and a longitudinal corner conveyor frame located in front of the transverse corner conveyor frame and adjacent to its corresponding auxiliary conveyor frame.

[0141] In the above technical solution, the second grinding and polishing device also has the same rotary conveyor, corner conveyor and auxiliary conveyor as described above;

[0142] In the above technical solution, the lifting roller frame includes a roller frame body that is slidably installed in the auxiliary conveyor frame. Several support rollers connected by a synchronous belt are rotatably connected to the roller frame body. The roller frame body is pneumatically or hydraulically driven to drive the support rollers to rise or fall, so as to lift the tray.

[0143] By adopting the above technical solution, through the coordinated arrangement of the corner conveyor, rotary conveyor and auxiliary conveyor, the slide of the first polishing device is first moved to the corner conveyor, and then the microcrystalline glass panel is transported to the next station by the transfer device. Then the empty slide is transported along the auxiliary conveyor into the rotary conveyor and returned to the right end of the first polishing device to load a new panel. This cycle is repeated, eliminating the need for manual handling of the slide, saving time and effort.

[0144] Example 8:

[0145] 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.

[0146] Furthermore, the transfer device 3 includes:

[0147] The transfer body 300 is located above the corner conveyor frame 122 adjacent to the output end of the grinding and polishing machine body 101. Support feet extending to the ground are connected and fixed at the four corners of the lower end of the transfer body 300.

[0148] The transfer head 301 is slidably mounted on the lower end of the transfer body 300;

[0149] The lifting head 302 is slidably installed on one side of the transfer head 301, and the lifting head 302 can slide up and down relative to the transfer head 301;

[0150] The transfer plate 303 is connected and fixed to the lower end of the lifting head 302. The lower end of the transfer plate 303 is provided with several suction cups to adsorb the microcrystalline glass panel on the slide plate 106.

[0151] Among them, a jet pipe 304 extending upwards from the corner conveyor frame 122 below the transfer body 300 is connected and fixed to one side.

[0152] In the above technical solution, a lead screw for driving the transfer head to move is installed inside the transfer machine body, and the transfer head is connected to the lead screw through a threaded slider.

[0153] By adopting the above technical solution, when the auxiliary conveyor with the microcrystalline glass panel moves to the bottom of the corner conveyor, the lifting head starts and drives the transfer plate to descend, so that the suction cup adheres to the panel and is fixed. Then the lifting head resets, the transfer head moves, and drives the panel to the input end of the cleaning device. Subsequently, the lifting head descends, releases the suction cup and resets, completing the transfer of the panel. This replaces the traditional mechanical clamping method, which can ensure that the panel will not fall off during the transfer process and avoid excessive clamping force that could damage the panel.

[0154] During polishing, water seeps between the panel and the slide, making it difficult for the panel to detach from the slide. By using an air jet pipe, compressed air can be sprayed into the gap between the panel and the slide before the transfer action to disperse the water and facilitate panel detachment.

[0155] Example 9:

[0156] 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.

[0157] Furthermore, the cleaning device 2 includes:

[0158] The cleaning machine body 200 is installed on the ground, and at least part of the cleaning machine body 200 extends downwards towards the transfer device 3;

[0159] Several conveyor rollers 201 are rotatably connected to both sides of the upper end of the cleaning machine body 200 along the length of the cleaning machine body 200.

[0160] Cleaning hood 202 is installed in the middle of the cleaning machine body 200;

[0161] The cleaning hood 202 includes a cleaning area and a drying area arranged along its length, and several water spray pipes are provided above the cleaning area.

[0162] The cleaning area also includes:

[0163] Several traction roller sets are arranged side by side along the length of the cleaning zone and are rotatably connected to the bottom of the cleaning zone. Each traction roller set includes two traction rollers connected by gear transmission.

[0164] Several brush 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 brush rollers connected by gear transmission. Two traction roller groups are arranged between two adjacent brush roller groups.

[0165] Among them, the middle of the cleaning hood 202 is equipped with a baffle plate that separates the cleaning area and the drying area, and the drying area is equipped with an air inlet pipe and an air outlet pipe that are connected to the drying area.

[0166] By adopting the above technical solution, the water spray pipes in the cleaning area can spray clean water or cleaning solution onto the upper and lower surfaces of the panel. Combined with two brush roller assemblies connected by gears, the panel can be thoroughly cleaned. The vertical arrangement of the brush roller assemblies ensures that both sides of the panel are adequately cleaned.

[0167] The baffle plate effectively separates the washing and drying areas, preventing moisture from the washing area from entering the drying area and affecting the drying effect. The air inlet duct in the drying area can introduce hot air, while the air outlet duct exhausts moisture, forming a good air circulation that can quickly remove moisture from the panel surface and achieve efficient drying of the panel.

[0168] Example 10:

[0169] 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.

[0170] Furthermore, the second cleaning device includes a second cleaning body and a second cleaning hood with the same structure as the first cleaning body 200 and the first cleaning hood 202, and the second cleaning body is installed on the ground.

[0171] The second transfer device is located downstream of the second polishing device, and the second cleaning machine is located downstream of the second transfer device. The second cleaning device also includes:

[0172] A water washing tank 400 is installed on the ground and located between the cleaning machine body 2 and the transfer device 2. The water washing tank 400 extends at least partially into the underside of the cleaning machine body 2.

[0173] Several conveyor rollers are rotatably connected to the washing tank 400 along the length of the washing tank 400;

[0174] By adopting the above technical solution, the second cleaning body and the second cleaning hood adopt the same structure as the first cleaning body and the first cleaning hood. They also have clearly defined cleaning and drying areas, as well as cleaning components such as water spray pipes, traction roller groups, and brush roller groups, ensuring that the panel can achieve the same level of deep cleaning as after being polished by the second polishing device.

[0175] The water washing tank is designed to pre-clean the panel, which prevents a large amount of impurities from directly contacting the brush rollers in the washing area. If the panel carries too many impurities into the brush roller assembly, the impurities may accumulate on the brushes, causing secondary pollution or scratches to the panel during washing.

[0176] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
