At present, in the process of single-sided polishing of glass, the surface of the glass is mainly polished by a grinding machine with abrasive liquid, wherein the grinding machine includes a grinding machine base welded from steel plates, a support frame installed on the grinding machine base, a grinding disc, a flip cylinder, a lifting cylinder and an electric control box, the cylinder body of the flip cylinder is locked on the support frame, and the flip cylinder is used to control the flipping of the upper grinding disc and the lower grinding disc. A motor for driving the rotation of the lower grinding disc is provided in the grinding machine base. The upper grinding disc descends under the drive of the lifting cylinder to fit with the lower grinding disc. During grinding, the lower grinding disc rotates clockwise and the upper grinding disc rotates counterclockwise. The product is ground with the abrasive between the upper grinding disc and the lower grinding disc to achieve the purpose of polishing the glass. When the above-mentioned grinding equipment is used to polish glass, due to the large vibration of the equipment body, the upper grinding disc surface shakes severely, the stability is poor, and the grinding disc pressure cannot be compensated.

Furthermore, when the above-mentioned grinding equipment is used to process products, it is necessary to regularly check the horizontal state of the equipment and adjust it in time, which makes the working efficiency of the grinding machine insufficient.

[0026] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0027] See also Figure 1 The utility model discloses a single-sided polishing machine which can accurately adjust the pressure of each grinding disc, evenly apply force to the product, monitor the horizontal state of the equipment in real time, and has high working efficiency. The single-sided polishing machine includes a support assembly 100, a first lifting assembly 200, and a turntable assembly 300, wherein the support assembly 100 is used as a machine platform of the entire single-sided polishing machine and is used to provide the lower grinding disc part of the polishing machine; the turntable assembly 300 is used to install the product to be polished and drive the product to rotate, so that the product rotates relative to the lower grinding disc during the process of contacting with the lower grinding disc, so as to remove the unevenness of the product surface and the surface of the product to be polished. Remove thickness; the first lifting assembly 200 supports and installs the flip assembly 300, and is used to adjust the vertical height of the flip assembly 300 and the angle of the flip assembly 300 in the vertical plane, so that the products to be polished arranged on the upper and lower surfaces of the flip assembly 300 can be alternately matched with the lower grinding disc and polished. In this way, when the lower grinding disc contacts and polishes the product below the flip assembly 300, the operator can simultaneously take away the product above the flip assembly 300 or clamp a new product to be polished above the flip assembly 300, thereby realizing continuous and uninterrupted operation of the polishing machine, thereby improving the working efficiency of the polishing machine.

[0028] For details, please combine Figure 1-3 The support assembly 100 includes a base 120 having a drainage groove 110 on its upper surface, a first drive motor 130 received in the inner cavity of the base 120, a lower grinding disc 140 located above the drainage groove 110, and a transmission mechanism 150 penetrating the bottom surface of the drainage groove 110 and drivingly connected to the output shaft of the first drive motor 130 and the lower grinding disc 140 respectively. In this embodiment, the diameter of the drainage groove 110 is greater than the diameter of the lower grinding disc 140, that is, the projection of the lower grinding disc 140 on the upper surface of the base 120 completely falls within the drainage groove 110, so that the abrasive waste liquid in the product polishing process drips into the drainage groove 110 through the edge of the lower grinding disc 140. Furthermore, the bottom of the drainage groove 110 is connected to an external waste liquid collection box so that the abrasive waste liquid can be collected and processed in a centralized manner. In addition, in this embodiment, the base 120 is an integrally formed cast iron frame, each side of the base 120 is provided with a baffle, and at least one side of the base 120 is provided with an openable and closable inspection door; the first drive motor 130 is a servo motor, and a reducer is installed between the first drive motor 130 and the transmission mechanism 150, so that the rotation speed of the lower grinding disc 140 meets the operation requirements. The transmission mechanism 150 is actually a mounting shaft of the lower grinding disc 140 connected to the reducer drive. In addition, the top of the transmission mechanism 150 is higher than the upper surface of the base 120, so that the lower grinding disc 140 is located above the base 120, avoiding interference between the flip assembly 300 and the base 120 during the product polishing operation.

[0029] In one embodiment, a through hole is provided on the bottom surface of the drain groove 110, and the support assembly 100 further includes a mounting ring 160 disposed in the drain groove 110 and around the edge of the through hole, and a cross roller bearing 170 fixed on the mounting ring 160 and cooperating with the transmission mechanism 150, and the mounting ring 160 is fixedly connected to the bottom surface of the drain groove 110. By providing the cross roller bearing 170, the rotation accuracy of the lower grinding disc 140 is improved, and the stability of the rotation of the lower grinding disc 140 is improved, and the shaking of the lower grinding disc 140 during the polishing operation is reduced, thereby improving the polishing quality of the product. A support foot 180 is also provided at the bottom of the base 120, which is used to raise the height of the entire polishing machine to prevent the electrical components in the base from being dampened by water; a control panel 190 electrically connected to each drive motor is also installed on the base 120, so that the operator can adjust the working parameters of the polishing machine by operating the control panel 190.

[0030] Please combine Figure 1-4The first lifting assembly 200 includes a first lifting frame 210 fixed to the upper surface of the base 120 and located on one side of the drain groove 110, a first screw rod 220 rotatably mounted on the first lifting frame 210 and extending along the height direction of the first lifting frame 210, a second driving motor 230 fixed to the first lifting frame 210 and driving the first screw rod 220 to rotate, a first nut 221 sleeved on the first screw rod 220 and threadedly matched with the first screw rod 220, a first mounting plate 240 fixedly connected to the first nut 221, and a third driving motor 250 fixed to the first mounting plate 240. In this embodiment, the first screw rod 220 is a precision ball screw, and the first lifting frame 210 is an integrally formed rectangular cast iron frame, including a left column and a right column arranged opposite to each other, an upper horizontal plate fixedly connected to the top of the left column and the right column, and a lower horizontal plate fixedly connected to the bottom of the left column and the right column. The left column, the right column, the upper horizontal plate and the lower horizontal plate form a first installation cavity. The first screw rod 220 is accommodated in the first installation cavity and rotates with the upper horizontal plate and the lower horizontal plate respectively. The second drive motor 230 is a servo motor. A reducer is provided between the second drive motor 230 and the bottom end of the first screw rod 220, so that the first screw rod 220 rotates at a relatively low speed, so as to accurately control the height of the first mounting plate 240 and the third drive motor 250, thereby achieving the purpose of controlling the height of the flip plate assembly 300. Specifically, in this embodiment, when the second drive motor 230 is working, the speed of the output end of the second drive motor 230 is reduced by the reducer, so that the first screw rod 220 rotates at a relatively low speed. Since the first screw rod 220 is threadedly matched with the first nut 221, in the process of the first screw rod 220 rotating, the first nut 221 will drive the first mounting plate 240 to move along the axial direction of the first screw rod 220 to achieve the lifting and lowering of the first mounting plate 240 and the flap assembly 300. The third drive motor 250 is used to control the flip assembly 300 to flip as a whole, so that the products on both sides of the flip assembly 300 can be polished alternately. Similarly, in this embodiment, the third drive motor 250 is a servo motor, and the output shaft of the third drive motor 250 is connected to a reducer, so that the flip assembly 300 can flip at a relatively low speed, so as to accurately adjust the horizontal state of the flip assembly 300.

[0031] Furthermore, in order to improve the stability of the lifting of the flap assembly 300, the first lifting assembly 200 also includes two first linear guides 260 fixed on the first lifting frame 210 and extending in the height direction of the first lifting frame 210, and two first sliders 270 slidably sleeved on the two first linear guides 260 in a one-to-one correspondence. The two first linear guides 260 are arranged opposite to each other, and the first mounting plate 240 is mounted astride the two first linear guides 260 and fixedly connected with the two first nuts. In this embodiment, the two first linear guides 260 are respectively fixed on the left column and the right column, and the first mounting plate 240 is mounted astride the two first linear guides 260. By increasing the indirect matching area between the first mounting plate 240 and the first lifting frame 210, it is beneficial to improve the stability of the first mounting plate 240 and reduce the stability of the lifting process of the first mounting plate 240 and the flap assembly 300.

[0032] Please combine Figure 1-7 The turning plate assembly 300 includes a control box 310 located above the lower grinding plate 140 and a driving assembly housed in the control box 310. A plurality of upper grinding plate mechanisms are respectively arranged above and below the control box 310. The side wall of the control box 310 is drivingly connected to the output shaft of the third driving motor 250, and the control box 310 is turned over by the output shaft of the third driving motor 250. The driving assembly includes a plurality of fourth driving motors 320 housed in the control box 310 and corresponding to each upper grinding plate mechanism one by one. The upper grinding plate mechanism includes a rotary joint 330, a rotary joint 330 sleeved on the rotary joint 330, and a rotary joint 330. 30 and connected to the external air pressure device, a cylinder 340, a piston 350 penetrating the inner cavity of the cylinder 340 and sleeved on the rotary joint 330, a vacuum plate 360 ​​installed at the bottom of the rotary joint 330 and rotating under the drive of the rotary joint 330, a fixture plate 370 fixed on the vacuum plate 360 ​​facing away from the rotary joint 330, and a grinding liquid guide 380 fixedly connected to the side of the vacuum plate 360 ​​close to the rotary joint 330 and used for receiving the grinding liquid, the grinding liquid guide 380 is used to transmit the grinding liquid to the contact part between the product and the lower grinding plate 140. The piston 350 is sealed with the cylinder 340 and the rotary joint 330 respectively, and the telescopic end of the piston 350 is fixedly connected to the vacuum plate 360. The output end of each fourth drive motor 320 passes through the top plate or the bottom plate of the control box 310 and is driven and connected to the rotary joint 330 of the corresponding upper grinding disc mechanism. In other words, each upper grinding disc mechanism is independently driven by a fourth drive motor 320 to control the rotation speed, and each fixture disc 370 is controlled to rise and fall by an independent piston 350. In this way, during the polishing operation, the pressure of each fixture disc 370 can be accurately controlled, so that each part of the product is evenly stressed to improve the polishing effect.

[0033] In this embodiment, a non-circular groove is provided at the bottom end of the rotary joint 330, and a plug rod is provided in the middle of one side of the vacuum disc 360 adjacent to the rotary joint 330. The plug rod is slidably inserted into the non-circular groove, and the annular side profile of the plug rod is adapted to the inner profile of the non-circular groove. In this way, during the rotation of the rotary joint 330, the rotary joint 330 will drive the plug rod and the vacuum disc 360 to rotate synchronously, thereby causing the fixture disc 370 fixed on the vacuum disc 360 and the product installed in the fixture disc 370 to rotate synchronously. At the same time, when the pressure of the fixture disc 370 needs to be adjusted, the piston 350 is pushed by the gas inside the cylinder 340 to approach or move away from the third drive motor to drive the vacuum disc 360 and the fixture disc 370 to rise and fall, and the distance between the fixture disc 370 and the lower grinding disc 140 is adjusted to achieve the purpose of adjusting the pressure of the fixture disc 370, so as to improve the force condition of the product. In addition, in this embodiment, it is necessary to ensure that the rotation directions of the fixture disc 370 and the lower grinding disc 140 are opposite to each other, so as to improve the polishing efficiency of the product.

[0034] In one embodiment, the fixture plate 370 is provided with a plurality of mounting grooves 371 for loading the products to be polished, and the bottom surface of the mounting grooves 371 is provided with air holes penetrating the side of the fixture plate 370 adjacent to the vacuum plate 360. The edge of the fixture plate 370 is fixed to the vacuum plate 360 ​​by screws, and the vacuum plate 360 ​​is connected to an external vacuum device. When it is necessary to clamp the product, the vacuum plate 360 ​​is connected to the external vacuum device to form a negative pressure in the mounting grooves 371, and then the products to be polished are placed in the mounting grooves 371. In this way, the products are adsorbed in the mounting grooves 371 under the action of the negative pressure to achieve the fixation of the products. In addition, in the present embodiment, a liquid inlet 372 is provided in the middle of the jig disk 370, and a first liquid outlet pipe corresponding to the liquid inlet 372 and a second liquid outlet pipe extending from the edge of the jig disk 370 and corresponding to the lower grinding disk 140 are provided on the grinding liquid guide 380. Thus, during the polishing process of the product, abrasive liquid can be simultaneously poured from the center and edge of the jig disk 370, so that the abrasive liquid can flow more evenly between the product and the lower grinding disk 140, so as to improve the uniformity of product grinding and thereby improve the flatness of the product.

[0035] The fourth drive motor 320 used in this solution is a servo motor. In one embodiment, the axial direction of the output shaft of the fourth drive motor 320 is the same as the extension direction of the rotary joint 330. Furthermore, a reducer is provided between the fourth drive motor 320 and the rotary joint 330. In another embodiment, the axial direction of the output shaft of the fourth drive motor 320 is perpendicular to the extension direction of the rotary joint 330, and the flap assembly 300 also includes a hollow right-angle reducer 390, which is respectively connected to the output shaft of the fourth drive motor 320 and the rotary joint 330. In actual production, the installation direction of the fourth drive motor 320 can be reasonably arranged according to the structure of the control box 310 and a suitable reducer can be selected, which will not be repeated here.

[0036] In addition, in this embodiment, a first disc 311 is provided on the top plate of the control box 310, a second disc 312 is provided on the bottom plate of the control box 310, four upper grinding disc mechanisms are evenly arranged along the circumferential direction on the first disc 311, and four upper grinding disc mechanisms are evenly arranged along the circumferential direction on the second disc 312. Correspondingly, eight fourth drive motors 320 are accommodated in the control box 310, four of which are fixed on the top plate of the control box 310, and the other four fourth drive motors 320 are fixed on the bottom plate of the control box 310. In this way, when the polishing machine performs a single polishing operation, the products on the four fixture discs 370 are simultaneously in contact with the lower grinding disc 140 and polished, which is conducive to improving the polishing efficiency. By flipping the control box 310 so that the products on the fixtures on both sides of the control box 310 are polished alternately with the lower grinding disc 140, the process of stopping the machine to pick up and place the products is eliminated, and the production capacity of the polishing machine reaches 400 PCS per hour. By independently controlling the pressure of each fixture disc 370 so that the product is evenly stressed, the polishing machine of this solution can polish the product with a yield of 95%. Compared with the traditional grinding machine equipment with a production capacity of 300 PCS per hour and a product yield of 85%, the production capacity of the polishing machine of this solution is significantly improved, and the product yield is also improved.

[0037] Please combine Figure 1-4 as well as Figure 8In one embodiment, the single-sided polishing machine also includes a second lifting assembly 400, which includes a second lifting frame 410 fixed to the upper surface of the base 120 and located on the other side of the drainage groove 110, a second screw rod 420 rotatably mounted on the second lifting frame 410 and extending along the height direction of the second lifting frame 410, a fifth driving motor 430 fixed to the second lifting frame 410 and driving the second screw rod 420 to rotate, a second nut 421 sleeved on the second screw rod 420 and threadedly matched with the second screw rod 420, two second linear guide rails 440 arranged oppositely and fixed on the second lifting frame 410 and extending along the height direction of the second lifting frame 410, two second sliders 450 slidably sleeved on the two second linear guide rails 440 in a one-to-one correspondence, a second mounting plate 460 fixedly connected to the second nut 421 and the two second sliders 450, and a support rod 470 fixed to the second mounting plate 460 and inserted into the side wall of the control box 310 to rotate with the control box 310. Preferably, the first lifting frame 210 and the second lifting frame 410 are both integrally formed rectangular cast iron frames. In this embodiment, the structure of the second lifting frame 410 is the same as that of the first lifting frame 210. A second installation cavity is also provided in the second lifting frame 410. The second screw rod 420 and the two second linear guide rails 440 are both provided in the second installation cavity. The lifting process of the second mounting plate 460 is the same as that of the first mounting plate 240. For details, please refer to the aforementioned description of the lifting process of the first mounting plate 240, which will not be repeated here. By providing the second lifting assembly 400, the second lifting assembly 400 and the first lifting assembly 200 jointly support the flip assembly 300, which further improves the stability of the lifting process of the flip assembly 300 and the stability of the installation of the flip assembly 300, and avoids the shaking of the fixture plate 370 during the product polishing process, so as to improve the product polishing effect.
