Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical devices, in particular to an automatic grinding machine using two-fluid spraying. BACKGROUND

[0002] At present, in the production process of liquid crystal screens, it is often necessary to perform grinding operation on the liquid crystal screen glass (or glass screen). The glass screen is generally cut from larger size glass into the required size of glass screen. The smoothness of the side surface of the cut glass screen is not enough, so a special grinding equipment is needed to grind the side surface of the glass screen. Grinding is generally performed by using a grinding wheel. In order to cool and remove impurities during grinding, cooling water and air knives are used. However, this method cannot solve the problem that impurities may run onto the upper and lower surfaces of the glass screen. These run-out impurities may scratch the surface of the glass screen, or may splash to other places and pollute the environment. In particular, for large size glass screens, this problem is more obvious. For small size glass screens, a protective cover can be designed to solve part of the problem. However, for large size glass screens, the design of the entire protective cover is not effective, the cost is high, and it is not easy to implement. SUMMARY

[0045] The following specific embodiments illustrate the detailed implementation of the present invention. Those skilled in the art can easily understand the advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented in other different ways, that is, different modifications and changes can be made without departing from the scope disclosed in the present invention.

[0046] The descriptions of positions such as up, down, left, and right in this embodiment are based on the orientation in the accompanying drawings, have no special meaning, and are not intended to limit the scope of protection of this invention.

[0047] Figures 2 to 7 The product dimensions shown are relatively small and are only used to simulate the state of the product during processing; they do not represent the actual product dimensions.

[0048] Example: An automated grinding machine employing a two-fluid spray system, such as... Figures 1 to 9As shown, the automated grinding machine includes a carrier 10 capable of rotating around the Z-axis and translating along the Y-axis, a machine base 1, and at least one grinding device disposed on the machine base; each of the grinding devices includes a grinding mechanism 21, an X-axis translation drive unit 22, and a Z-axis translation drive unit 23, which drive the grinding mechanism to move along the X and Z axes, respectively;

[0049] The grinding mechanism 21 includes a grinding box 211, a grinding wheel 212 that can rotate along the Z-axis, an upper functional seat 213, and a lower functional seat 214. The grinding wheel is located inside the grinding box. The grinding position where the product is located is defined as the grinding position. The grinding box has a transverse slot corresponding to the grinding position (the main purpose is to allow the grinding wheel to contact the side of the product so that the side of the product can be ground). The upper functional seat 213 is installed above the grinding position, and the lower functional seat 214 is installed below the grinding position.

[0050] The upper functional seat is equipped with a cooling structure, an upper exhaust structure and an upper two-fluid generating structure. The cooling structure is used to cool the grinding wheel during grinding. The upper exhaust structure draws away grinding impurities from above. The upper two-fluid generating structure prevents impurities from entering the upper surface of the product 100 that does not need to be ground.

[0051] The lower functional seat is equipped with a lower exhaust structure and a lower two-fluid generating structure. A main exhaust chamber 216 is installed below the grinding box. The main exhaust chamber is connected to both the grinding box and the lower exhaust structure. The lower two-fluid generating structure prevents impurities from entering the lower surface of the product that does not require grinding.

[0052] In this embodiment, preferably, the grinding device is provided in two sets, namely a first grinding device 2 and a second grinding device 3, which are arranged at intervals along the Y-axis. The first grinding device is a coarse grinding device and the second grinding device is a fine grinding device.

[0053] In this way, the product moves from left to right along the Y direction once, and one side of the product can be coarsely ground and finely ground to meet the surface finish requirements, resulting in high production efficiency.

[0054] In this embodiment, as Figures 3 to 9 As shown, the upper functional seat 213 includes an upper functional seat body 2131 and an upper base plate 2132, with the upper base plate installed at the bottom of the upper functional seat body; the upper functional seat is divided into an upper two-fluid cavity 2134 and an upper exhaust cavity 2135 by an upper partition 2133; an upper two-fluid generator 2136 is installed on the cavity wall of the upper two-fluid cavity, and a positive pressure air inlet 2137 is also provided on the cavity wall of the upper two-fluid cavity; an external exhaust device 24 is connected to the cavity wall of the upper exhaust cavity;

[0055] The cooling structure is provided in the side wall of the upper functional seat body, near the grinding wheel.

[0056] In this embodiment, as Figure 6 and Figure 8 As shown, the cooling structure includes two cooling water inlets 21391, two transverse cooling channels 21392, two longitudinal cooling channels 21393, a cooling chamber 21394, and multiple spray holes 21395. The cooling water inlets are located on both sides of the upper part of the upper functional seat body. Each cooling water inlet is connected to one end of a transverse cooling channel, and the other end of each transverse cooling channel is connected to the upper end of a longitudinal cooling channel. The lower ends of the two longitudinal cooling channels are simultaneously connected to both ends of the cooling chamber. The cooling chamber is simultaneously connected to the multiple spray holes.

[0057] The inner wall surface at the lower end of the upper functional seat body is an arc-shaped surface, and the water spray holes are arranged sequentially and evenly at intervals on the arc-shaped surface.

[0058] In this embodiment, the cooling chamber has a structure that is wider at the top and narrower at the bottom. The bottom of the cooling chamber is connected to multiple water spray holes. This structural design can ensure that the cooling water has sufficient pressure when it is sprayed out, resulting in a stronger cooling effect, and can also better wash away grinding impurities.

[0059] In this embodiment, as Figure 6 and Figure 9 As shown, the upper base plate 2132 includes a first upper bottom edge 21321, a second upper bottom edge 21322, and an upper base plate body 21323. The bottom of the inner cavity wall of the upper functional seat body is aligned and sealed with the first upper bottom edge, the bottom of the upper partition is aligned and sealed with the second upper bottom edge, and the bottom of the upper fluid cavity is aligned and sealed with the upper base plate body.

[0060] The upper partition is arc-shaped, and the first upper bottom edge and the second upper bottom edge are also arc-shaped;

[0061] The gap between the first upper bottom edge and the second upper bottom edge forms an upper exhaust port 21324. In this embodiment, the upper exhaust structure mainly refers to the aforementioned upper exhaust cavity and upper exhaust port.

[0062] In this embodiment, as Figure 5 , Figure 6 and Figure 9 As shown, the upper base plate body has multiple inclined upper fluid outlets 21325 on the side near the second upper bottom edge; as Figure 7 As shown, the inclination angle α of the upper two-fluid outlet is 40 to 70°. In this embodiment, the upper two-fluid generating structure mainly refers to the aforementioned upper two-fluid cavity, upper two-fluid generator, and upper two-fluid outlet.

[0063] In this embodiment, as Figure 5 and Figure 6 As shown, the lower functional seat 214 includes a lower functional seat body 2141 and a lower base plate 2142 installed on the upper part of the lower functional seat body. The lower functional seat is divided into a lower two-fluid cavity 2144 and a lower exhaust cavity 2145 by a lower partition plate 2143. A lower two-fluid generator 2146 is installed on the cavity wall of the lower two-fluid cavity, and a positive pressure air inlet 2137 is also provided on the cavity wall of the lower two-fluid cavity. The lower exhaust cavity is connected to the main exhaust cavity, and an external exhaust device is connected to the cavity wall of the main exhaust cavity.

[0064] The inner wall surface of the lower partition is also an arc-shaped surface;

[0065] The lower base plate, positioned opposite the lower fluid cavity, is provided with multiple inclined lower fluid outlets 2148; such as Figure 7 As shown, the inclination angle β of the lower fluid outlet is 40 to 70°;

[0066] The lower base plate is provided with a lower exhaust port 2149, which is connected to the lower exhaust cavity; the lower part of the lower exhaust cavity is connected to the main exhaust cavity.

[0067] In this embodiment, the lower two-fluid generating structure mainly refers to the lower two-fluid cavity, the lower two-fluid generator, and the lower two-fluid outlet mentioned above. In this embodiment, the lower exhaust structure mainly refers to the lower exhaust cavity and the lower exhaust port mentioned above.

[0068] In this embodiment, both the upper and lower fluid outlets are inclined. The resulting fluid mixture (water vapor mixture) can better blow or rush impurities generated during the grinding process to the inside (the side closer to the grinding wheel), preventing them from being splashed or blown to the outside by the cooling water. In other words, impurities will concentrate at the grinding position, making it easier for them to be removed by the external ventilation device. They will not move to the outside and therefore will not move to the upper and lower surfaces of the glass screen, thus preventing them from being contaminated or scratched.

[0069] In this embodiment, the multiple rings of the upper two fluid outlets refer to the center of the grinding wheel. The multiple rings are not strictly circles, but rather grooves in the shape of "︹" that surround the grinding position. This is to provide better blocking effect, keeping impurities at the grinding position and preventing them from spreading to other un-grinded upper and lower surfaces of the glass screen.

[0070] Therefore, in this embodiment, through the rational design of the upper and lower functional seats, the cooling water mainly serves to cool down the grinding process and blow away impurities; the sprayed high-pressure two-fluid mainly directs the impurities and water generated during the grinding process towards the side closest to the grinding wheel, preventing them from spreading outwards from the product. Simultaneously, the external exhaust device generates negative pressure, which can collect the impurities, cooling water, and two-fluid generated during the grinding process. In short, the grinding machine of this invention can perform excellent cleaning while grinding, eliminating the need for a separate cleaning station, and the impurities generated during grinding will not contaminate other surfaces of the product.

[0071] In this embodiment, as Figure 5 As shown, the grinding box 211 is divided into an upper cavity 2112 and a lower cavity 2113 by a transverse partition 2111, and the grinding wheel is located in the upper cavity; a longitudinal partition 2114 is provided at the bottom of the transverse partition, and a through hole 2115 is provided on the left side of the transverse partition to connect the upper cavity and the lower cavity; the longitudinal partition is aligned with the upper part of the main exhaust cavity to separate the lower cavity from the lower exhaust cavity, and the lower cavity and the lower exhaust cavity are simultaneously connected to the main exhaust cavity.

[0072] In this embodiment, the inner sidewall 21411 of the lower functional seat body and the sidewall of the grinding box together form the upper cavity.

[0073] In this embodiment, as Figure 1 and Figure 4 As shown, the exhaust device connected to the upper exhaust chamber and the exhaust device connected to the wall of the main exhaust chamber are the same exhaust device. The exhaust device 24 includes an exhaust pipe 241, on which an automatic exhaust valve 242 and an exhaust flow meter 243 are installed. The exhaust device is existing technology and will not be described in detail; it is sufficient that it can generate negative pressure to smoothly draw away and discharge waste and other impurities.

[0074] In this embodiment, the upper surface of the lower base plate is initially a flat surface from the inside out, then slopes downwards. This structural design is primarily to avoid obstacles from the vehicle. To provide sufficient support, the vehicle also needs to support the edges of the product; therefore, the edges of the vehicle are designed in an inverted triangular shape. To avoid obstacles, the upper surface of the lower base plate needs to be designed as a sloping surface.

[0075] In this embodiment, as Figure 3 As shown, the upper end of the central shaft of the grinding wheel is connected to a grinding wheel rotation drive mechanism 215 capable of driving its rotation. The grinding wheel rotation drive mechanism may include, for example, a servo motor and a rotary bearing, as long as they can all drive the grinding wheel to rotate and the grinding wheel can extend into the grinding box without interfering with the upper end of the grinding box. This is prior art and will not be described in detail. Figure 1As shown, a protective cover 217 is fitted over the grinding wheel rotation drive mechanism.

[0076] In this embodiment, both the X-axis translation drive unit and the Z-axis translation drive unit are transmission structures consisting of a servo motor and a lead screw nut. This is existing technology and will not be described in detail. As long as the X-axis and Z-axis translation of the grinding mechanism can be achieved, it is acceptable.

[0077] In this embodiment, the carrier is capable of rotating around the Z-axis and translating along the Y-axis. The rotation of the carrier can be achieved by a servo motor in conjunction with a cam divider, and the translation of the carrier along the Y-axis can be achieved by a servo motor in conjunction with a lead screw and nut transmission structure. The above structures are all existing technologies and will not be described in detail. The product (or glass screen) can be vacuum-adheded onto the carrier, or other fixing methods can be used.

[0078] The working principle and process of this invention:

[0079] The product to be ground (a glass screen in this embodiment) is placed on the carrier. The X-axis translation drive unit and Z-axis translation drive unit of the first grinding device drive the grinding mechanism (for coarse grinding) into position. At the same time, the X-axis translation drive unit and Z-axis translation drive unit of the second grinding device drive the grinding mechanism (for fine grinding) into position. The grinding wheel rotation drive mechanism drives the corresponding grinding wheel to rotate and grind one side of the product. Meanwhile, the carrier moves along the Y-axis. This side of the product undergoes coarse grinding and fine grinding in succession to achieve a relatively ideal grinding effect. Since the carrier can also rotate 360°, other sides of the product can also be ground.

[0080] The specific grinding process is as follows:

[0081] When the grinding wheel grinds the side of the product, cooling water flows through two cooling water inlets 21391, two transverse cooling channels 21392, two longitudinal cooling channels 21393, and a cooling chamber 21394, and is finally sprayed out through multiple spray holes to the grinding position of the grinding wheel and the product for cooling and removing impurities. Above the grinding position, an upper fluid generator produces a large amount of fluid. Under high pressure (accessed through a positive pressure inlet), the fluid flows through the upper fluid chamber and is sprayed obliquely inwards towards the grinding position from the upper fluid outlet. Similarly, below the grinding position, the fluid is sprayed obliquely inwards towards the grinding position from the lower fluid outlet. The fluids at both positions ensure that impurities generated during the grinding process remain only at the grinding position, preventing splashing or flow onto the outer surfaces of the product and avoiding scratches. Simultaneously, impurities and waste liquid generated above the grinding position are collected from above through the upper exhaust port and upper exhaust chamber. The exhaust path is... Figure 5The dotted arrow at the top; secondly, impurities and waste liquid generated during grinding are mainly collected from below through the lower exhaust port and lower exhaust chamber into the main exhaust chamber (this part of the exhaust path is...). Figure 5 (The dotted arrow on the lower right of the image) A portion will also enter the main exhaust chamber through the upper cavity and through-hole, and finally be collected (this part's exhaust path is...) Figure 5 (See the dotted arrow on the lower left of the image). This design of the ventilation system ensures that impurities above, below, near the grinding wheel, and near the product can be effectively collected, guaranteeing optimal collection results.

[0082] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure made using the content of the present invention specification and drawings, or directly or indirectly applied to other related technical fields, is similarly included within the patent protection scope of the present invention.
