Description

Technical Field

[0001] The present invention relates to the technical field of table processing, and specifically to an automated production device for an intelligent table. Background Art

[0002] An intelligent table is a new type of table integrating technologies such as the Internet of Things, sensors, and artificial intelligence, and has functions such as automatic heating, intelligent temperature control, wireless charging, dish recommendation, and voice interaction, which can improve the dining experience and convenience. It is usually equipped with a circular glass turntable to ensure that the food on the turntable is evenly distributed, facilitating the diners sitting around to easily pick up the dishes from any angle and at the same distance, and avoiding the inconvenience of picking up food caused by the corner areas of a square table. When the glass turntable is produced, the glass needs to be cut. After the glass is cut, the surface of the glass can be softened by flame and impacted by firepower, which can solve some texture problems on the surface of the glass products, but the flatness of the processed glass surface will be reduced to some extent, and the glass surface needs to be polished.

[0003] Currently, the general method for polishing the glass turntable of a table is to use a large machine to polish the table. When polishing, the table cannot be fixed well, which easily leads to uneven polishing. In addition, there are also some polishing methods for tables that use a sand belt to manually polish the table, which takes too long and has low work efficiency.

[0004] After retrieval, a glass turntable polishing device for a circular table is disclosed in the publication number: CN110860974A. The technical problem of the present invention is how to design a glass turntable polishing device for a circular table that does not generate noise and pollution during polishing, and can fix the table during polishing to make the glass turntable of the table polished evenly and with high polishing efficiency. A glass turntable polishing device for a circular table includes a first support frame, a second support frame, a motor, a bearing seat, etc.; a second support frame is provided at the lower part of the left inner wall of the first support frame, a motor is installed in the second support frame, the motor is inclined at an angle of 45 degrees, a rotating shaft is connected to the output shaft of the motor, a bearing seat is provided in the middle of the right side outside the second support frame, and the rotating shaft is installed in the bearing seat.

[0005] When polishing both sides of the glass turntable in the above application, it needs to be manually flipped, which is inconvenient to use and affects the polishing efficiency. Summary of the Invention

[0010] Preferably, pressure sensors are respectively fixedly arranged on both sides of the limiting frame, and an electric push rod is fixedly connected to the center of the side wall of the bracket.

[0011] Preferably, slots are opened on the surfaces of the limiting frame and the clamping seat.

[0012] Preferably, the clamping plate includes an outer connecting member, and an inner limiting member is slidably connected to the inside of the outer connecting member. An elastic member II is fixedly arranged between the outer connecting member and the inner limiting member. The inner limiting member is made of ferromagnetic materials.

[0013] Preferably, the clamp further includes two magnetic blocks II, which are respectively fixedly installed at the inner top wall and inner bottom wall of the bracket.

[0014] Preferably, the grinding assembly includes a rotating shaft, and both ends of the rotating shaft are rotatably connected to the mounting plate. A servo motor is fixedly connected to the top of the mounting plate, and the driving end of the servo motor is fixedly connected with the rotating shaft. A plurality of grinding plates are annularly rotatably connected to the side wall of the rotating shaft through shafts. A driving mechanism is installed on the surface of the rotating shaft to drive the grinding plates to rotate.

[0015] Preferably, the driving mechanism includes a plurality of first gears and an L-shaped support frame. The first gears are fixedly installed on the outer wall of the shaft of the grinding plate. One end of the support frame is slidably connected to the mounting plate. The rotating shaft penetrates through the support frame. A grinding motor is fixedly connected to the lower side wall of the support frame. A second gear is fixedly connected to the driving end of the grinding motor. An elastic member four is sleeved on the surface of the rotating shaft. Limiting protrusions are respectively arranged above and below the elastic member four. The limiting protrusions are fixedly connected to the rotating shaft. Extension plates are respectively fixedly connected to both sides of the support frame.

[0016] Preferably, the grinding assembly further includes two lower pressing plates. A telescopic rod is fixedly connected to the side wall of the lower pressing plate. The other end of the telescopic rod is fixedly connected to the side wall of the base. A pulling rope is fixedly connected to the side wall of the lower pressing plate. The other end of the pulling rope is fixedly connected to the mounting plate. An inclined surface and a horizontal surface are formed on the inner top wall of the lower pressing plate from outside to inside.

[0017] Working principle: When grinding the glass turntable, place the glass turntable on the lower clamping seat. Then, through the operation of the bidirectional electric sliding table, drive the two clamping seats to move synchronously towards each other, so that the two clamping seats abut against the upper and lower ends of the glass turntable for clamping and limiting, which is suitable for fixing glass turntables of various diameters. After the glass turntable is fixed, drive the grinding assembly to move towards the glass turntable side through the cylinder, so that the grinding assembly grinds the glass turntable. After grinding is completed, the cylinder contracts. Then, drive the rotating frame to rotate 180° through the operation of the driving motor, so that the other side of the glass turntable faces the grinding assembly. Through the cylinder extending again, the grinding assembly grinds the other side of the glass turntable, thereby realizing the automatic double-sided grinding of the glass turntable and improving the processing efficiency of the dining table.

[0018] The electric push rod is used to support the glass turntable, preventing the glass turntable from moving backward during grinding and affecting the grinding effect. The elastic force of the first elastic member is used to elastically limit the position-limiting frame, so that the position-limiting frame is located on both sides of the clamping seat. When the electric push rod extends to push the glass turntable to move horizontally until it touches the pressure sensor on the outer side of the position-limiting frame, the pressure sensor receives the pressure signal and transmits the data to the controller. The controller controls the electric push rod to stop running to avoid damaging the glass turntable. When the glass turntable moves and fits against the side wall of the position-limiting frame, the end face of the glass turntable and the clamping seat are in the same vertical plane. Thus, when the grinding assembly grinds, it can be avoided that the grinding part of the grinding assembly is stuck by the clamping seat because the grinding part is too long, making the grinding assembly applicable to grinding glass turntables with various diameters. When the glass turntable is turned over, the electric push rod first contracts and then extends again after turning over, pushing the glass turntable to the other end face of the clamping seat for grinding. And the air cylinder pushes the adsorption frame to move through the clamping plate. At this time, the magnetic suction force between the first magnet and the adsorption frame drives the position-limiting frame to move towards the adsorption frame, so that the position-limiting frame automatically rises or falls and is no longer between the glass turntable and the grinding assembly, avoiding affecting the grinding of the glass turntable by the grinding assembly.

[0019] The air cylinder pushes the grinding assembly to move, and the extension plate presses against the inclined surface to push the lower pressing plate to move synchronously. When the outermost sandpaper fits against the glass turntable, the telescopic rod is pulled to the maximum extension amplitude. At this time, the extension plate descends along the inclined surface to the horizontal plane under the restriction of the telescopic rod, so that the extension plate drives the support frame to descend. The descent of the support frame drives the second gear to descend. The second gear descends and meshes with the first gear directly below. Subsequently, the grinding motor two drives the second gear to rotate. The second gear drives the first gear to rotate. The first gear drives the grinding plate to rotate to grind the glass turntable. When grinding for the first time, sandpaper with a smaller rotation count is used for grinding and gradually switched to sandpaper with a larger rotation count in the subsequent process to improve the grinding effect. The specific switching method is as follows: by contracting the air cylinder, the extension plate and the lower pressing plate are staggered. At this time, the support frame slides upward under the elastic force of the fourth elastic member, so that the second gear and the first gear are staggered. At the same time, the lower pressing plate is pulled by the pull rope to move away from the glass turntable, so as to leave space for the rotation of the rotating frame. By driving the rotating shaft to rotate 90° by the servo motor, the grinding plate can be switched. Finally, by extending the air cylinder again, the second gear and the first gear of the grinding plate are meshed again for transmission, so that the switched grinding plate is sequentially driven to rotate by a single set of grinding motors, thereby reducing the equipment investment and cost.

[0020] The present invention provides an automatic production equipment for an intelligent dining table. It has the following beneficial effects: 1. The present invention clamps and limits the upper and lower ends of the glass turntable by the clamping seat, is applicable to fixing glass turntables with various diameters, and drives the glass turntable to rotate 180° to turn it over through the driving motor, and can realize automatic grinding of both sides of the glass turntable, improving the processing efficiency of the dining table.

[0021] 2. The present invention provides support for the glass turntable by means of an electric push rod to prevent the glass turntable from moving backward during grinding, which affects the grinding effect. Moreover, a pressure sensor is used to detect the pressure of the electric push rod on the glass turntable to avoid damaging the glass turntable.

[0022] 3. The present invention places the glass turntable between the clamping plate and the limiting frame to automatically adjust the orientation of the glass turntable, making the glass turntable vertically placed, avoiding the inclination of the glass turntable during manual placement, and enabling the glass turntable to be vertically facing the grinding assembly for grinding after placement, ensuring the grinding accuracy.

[0023] 4. The present invention switches the grinding plates through a servo motor, and a single set of grinding motors sequentially drives the switched grinding plates to rotate for grinding, which can reduce the equipment investment and lower the cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0027] Please refer to the attached Figure 1 -attached Figure 3 , an automated production device for an intelligent dining table provided by an embodiment of the present invention includes a base 1 and a controller. A U-shaped bracket 2 is fixedly arranged above the base 1. The outer wall of the bracket 2 is rotatably connected with a U-shaped rotating frame 3. A bidirectional electric sliding table 4 is fixedly connected to the side wall of the rotating frame 3. Two sliders of the bidirectional electric sliding table 4 are respectively fixedly connected with support arms 5. Clamps 6 are respectively installed at the upper and lower ends of the support arms 5. The clamp 6 includes a clamping seat 61 with a groove on the surface. The side wall of the clamping seat 61 is fixedly connected with one end of the support arm 5. The top of the bracket 2 is fixedly connected with a mounting frame 7. The top of the mounting frame 7 is fixedly connected with a driving motor 8. The driving end of the driving motor 8 is fixedly connected with the rotating frame 3. The driving end of the driving motor 8 and the rotating shaft between the rotating frame 3 and the bracket 2 are on the same vertical line. A cylinder 10 is fixedly connected to the side wall of the base 1. The driving end of the cylinder 10 is fixedly connected with a mounting plate 11. A grinding assembly 9 is installed on the surface of the mounting plate 11. The controller is electrically connected to the bidirectional electric sliding table 4, the driving motor 8 and the cylinder 10.

[0028] Specifically, the groove can increase the contact points between the clamping seat 61 and the glass turntable, improving the clamping stability. When grinding the glass turntable, place the glass turntable on the lower clamping seat 61, and then operate the bidirectional electric sliding table 4 to drive the two clamping seats 61 to move synchronously in opposite directions, so that the two clamping seats 61 abut against the upper and lower ends of the glass turntable for clamping and limiting, which is applicable to fixing glass turntables of various diameters. After the glass turntable is fixed, the cylinder 10 drives the grinding assembly 9 to move towards the glass turntable side, so that the grinding assembly 9 grinds the glass turntable. After grinding, the cylinder 10 retracts, and then the driving motor 8 operates to drive the rotating frame 3 to rotate 180°, so that the other side of the glass turntable faces the grinding assembly 9. The cylinder 10 extends again to make the grinding assembly 9 grind the other side of the glass turntable, thereby realizing the automatic double-sided grinding of the glass turntable and improving the processing efficiency of the dining table.

[0029] Please refer to the attached Figure 3 -attached Figure 4, both ends of the clamping seat 61 are slidably connected in the vertical direction with a U-shaped limiting frame 62. A first elastic member 63 is fixedly connected to the inner wall of the limiting frame 62. The first elastic member 63 can be a leaf spring, a helical spring, a torsion bar spring, a rubber spring, etc. In this embodiment, a helical spring is used. The other end of the first elastic member 63 is fixedly connected to the clamping seat 61. A first magnetic block 69 is fixedly connected to the outer side wall of the limiting frame 62. Pressure sensors 65 are fixedly arranged on both sides of the limiting frame 62 respectively. An electric push rod 12 is fixedly connected to the center of the side wall of the bracket 2. The controller is electrically connected to the pressure sensors 65 and the electric push rod 12. Pre-support members 14 are slidably connected to both sides of the clamping seat 61 respectively. One end of each pre-support member 14 is fixedly connected to a third elastic member 13. The third elastic member 13 can be a leaf spring, a helical spring, a torsion bar spring, a rubber spring, etc. In this embodiment, a helical spring is used. The other end of the third elastic member 13 is fixedly connected to the outer wall of the clamping seat 61. A smooth rubber pad is fixedly arranged at the end of the pre-support member 14 facing the glass turntable.

[0030] Specifically, when the clamping seat 61 abuts against the glass turntable, the extrusion force applied by the glass turntable to the pre-support member 14 is used to push the pre-support member 14 to slide in a direction away from the glass turntable. When the glass turntable is pushed to move, the two clamping seats 61 are controlled by the bidirectional electric sliding table 4 to move in opposite directions, so that a certain gap is opened between the two clamping seats 61. At this time, the pre-support member 14 abuts against the glass turntable through the elastic force of the third elastic member 13 for elastic limiting. Thus, when the glass turntable is pushed, the resistance applied by the clamping seat 61 to the glass turntable is reduced. At the same time, the glass turntable is prevented from falling through the elastic limiting of the pre-support member 14, which is convenient for the glass turntable to slide horizontally. During grinding, the electric push rod 12 abuts against the glass turntable to provide support for it, preventing the glass turntable from moving backward during grinding and affecting the grinding effect. The limiting frame 62 is elastically limited by the elastic force of the first elastic member 63, so that the limiting frame 62 is located on both sides of the clamping seat 61. When the electric push rod 12 extends to push the glass turntable to move horizontally until it abuts against the pressure sensor 65 on the outer side of the limiting frame 62, the pressure sensor 65 receives the pressure signal and transmits the data to the controller. The controller controls the electric push rod 12 to stop running to avoid damaging the glass turntable. When the glass turntable moves and fits against the side wall of the limiting frame 62, the end face of the glass turntable and the clamping seat 61 are in the same vertical plane. Thus, when the grinding assembly 9 grinds, it is avoided that the grinding member of the grinding assembly 9 is stuck by the clamping seat 61 due to the excessive length of the grinding member, so that the grinding assembly 9 is applicable to grinding glass turntables of various diameters. When the glass turntable is turned over, the electric push rod 12 first contracts and then extends again after turning over, and the glass turntable is pushed to the other end face of the clamping seat 61.

[0031] Please refer to the appendix Figure 3 , the fixture 6 further includes two U-shaped adsorption frames 64, and the two adsorption frames 64 are respectively fixedly installed on the upper and lower sides of the mounting plate 11. The adsorption frames 64 are made of ferromagnetic materials.

[0032] Specifically, during grinding, the air cylinder 10 pushes the adsorption frame 64 to move through the clamping plate. At this time, the magnetic suction force between the first magnet 69 and the adsorption frame 64 drives the limit frame 62 to move towards the adsorption frame 64, so that the upper and lower limit frames 62 automatically rise or fall and are no longer between the glass turntable and the grinding assembly 9, avoiding affecting the grinding of the glass turntable by the grinding assembly 9.

[0033] Please refer to the appendix Figure 5 As shown in the figure, slots are provided on the surfaces of the limit frame 62 and the clamping seat 61. A clamping plate 66 is slidably connected to the inner side wall of the slot on the surface of the limit frame 62. A threaded rod 67 is rotatably connected to the side wall of the clamping plate 66, and the threaded rod 67 penetrates and is threadedly connected to the limit frame 62.

[0034] Specifically, the slot is used for the clamping plate 66 to pass through. By rotating the bolt rod, the clamping plate 66 is driven to slide, and the distance between the clamping plate 66 and one end of the adjacent limit frame 62 is adjusted, and the distance is kept moving with the thickness of the glass turntable to be processed. Thus, when placing the glass turntable, the glass turntable can be placed between the clamping plate 66 and the limit frame 62 to automatically adjust the orientation of the glass turntable, so that the glass turntable is vertically placed, avoiding the glass turntable being inclined and fixed during manual placement, and enabling the glass turntable to be vertically facing the grinding assembly 9 for grinding after placement, ensuring the grinding accuracy.

[0035] Please refer to the appendix Figure 4 - appendix Figure 6 As shown in the figure, the clamping plate 66 includes an outer connecting member 661. An inner limiting member 662 is slidably connected inside the outer connecting member 661. An elastic member 663 is fixedly arranged between the outer connecting member 661 and the inner limiting member 662. The elastic member 663 can be a leaf spring, a helical spring, a torsion bar spring, a rubber spring, etc. In this embodiment, a helical spring is used, and the inner limiting member 662 is made of a ferromagnetic material. The fixture 6 further includes two second magnets 68, and the two second magnets 68 are respectively fixedly installed at the inner top wall and the inner bottom wall of the bracket 2.

[0036] Specifically, the outer connecting member 661 is used to connect with the slot. The inner limiting frame 62 slides towards the direction of the glass turntable under the elastic force of the elastic member 663, so as to support the rear side of the glass turntable. After one side of the glass turntable is ground and the surface is changed, the inner limiting member 662 rotates to the position of the second magnet 68. Through the magnetic suction force applied by the second magnet 68 to the inner limiting member 662, the inner limiting member 662 is pulled to move away from the glass turntable, so that the inner limiting member 662 is no longer in contact with the glass turntable, thus enabling the electric push rod 12 to smoothly push the glass turntable to move.

[0037] Please refer to the appendix Figure 8, the grinding assembly 9 includes a rotating shaft 91. Both ends of the rotating shaft 91 are rotatably connected to the mounting plate 11. The top end of the mounting plate 11 is fixedly connected with a servo motor 15. The driving end of the servo motor 15 is fixedly connected with the rotating shaft 91. A plurality of grinding plates 92 are annularly rotatably connected to the side wall of the rotating shaft 91 through a shaft. A driving mechanism is installed on the surface of the rotating shaft 91 to drive the grinding plates 92 to rotate.

[0038] Specifically, the cylinder 10 operates to push the mounting plate 11 and the grinding assembly 9 to move towards the glass turntable for grinding. When the grinding plate 92 is in contact with the glass turntable, the driving mechanism drives the grinding plate 92 to rotate for grinding.

[0039] Please refer to the appendix Figure 7 - appendix Figure 8 , the driving mechanism includes a plurality of first gears 93 and an L-shaped support frame 94. The first gears 93 are fixedly installed on the outer wall of the shaft of the grinding plate 92. One end of the support frame 94 is slidably connected to the mounting plate 11. The rotating shaft 91 passes through the support frame 94. A grinding motor 95 is fixedly connected to the lower side wall of the support frame 94. The driving end of the grinding motor 95 is fixedly connected with a second gear 96. An elastic member four 97 is sleeved on the surface of the rotating shaft 91. The elastic member four 97 can be a leaf spring, a helical spring, a torsion bar spring, a rubber spring, etc. In this embodiment, a helical spring is adopted. Limiting protrusions 16 are respectively arranged above and below the elastic member four 97. The limiting protrusions 16 are fixedly connected with the rotating shaft 91. Extension plates 98 are respectively fixedly connected to both sides of the support frame 94. The grinding plate 92 includes a plate body and sandpaper fixed on the surface of the plate body. The mesh numbers of several pieces of sandpaper are different and gradually increase. The grinding assembly 9 further includes two lower pressing plates 99. A telescopic rod 21 is fixedly connected to the side wall of the lower pressing plate 99. The other end of the telescopic rod 21 is fixedly connected to the side wall of the base 1. A pull rope 20 is fixedly connected to the side wall of the lower pressing plate 99. The other end of the pull rope 20 is fixedly connected to the mounting plate 11. The inner top wall of the lower pressing plate 99 is provided with an inclined surface and a horizontal surface from outside to inside.

[0040] Specifically, during grinding, the cylinder 10 pushes the grinding assembly 9 to move, and the extension plate 98 pushes against the inclined surface to push the lower pressure plate 99 to move synchronously. When the outermost sandpaper is in contact with the glass turntable, the length of the telescopic rod 21 is preset so that the telescopic rod 21 is pulled to the maximum extension range at this time, and the extension plate 98 will drop along the inclined surface to the horizontal plane under the restriction of the telescopic rod 21, so that the extension plate 98 drives the support frame 94 to drop, and the drop of the support frame 94 drives the gear 2 96 to drop, and the gear 2 96 drops and meshes with the gear 1 93 directly below, and then the grinding motor 952 drives the gear 2 96 to rotate, and the gear 2 96 drives the gear 1 93 to rotate, and the gear 1 93 drives the grinding plate 92 to rotate to grind the glass turntable. During the initial grinding, the sandpaper with a smaller mesh number is rotated for grinding and in the subsequent grinding, the grinding plate 92 is rotated to grind the glass turntable. Gradually switch to sandpaper with a larger mesh number for polishing to improve the polishing effect. The specific switching method is that the cylinder 10 is contracted to stagger the extension plate 98 and the lower pressure plate 99. At this time, the support frame 94 slides upward under the elastic force of the elastic member 4 97, so that the gear 2 96 and the gear 1 93 are staggered. At the same time, the pull rope 20 is used to pull the lower pressure plate 99 away from the glass turntable, thereby leaving space for the rotation of the rotating frame 3. The servo motor 15 drives the rotating shaft 91 to rotate 90°, and the polishing plate 92 can be switched. Finally, the cylinder 10 is extended again, so that the gear 2 96 and the gear 1 93 of the polishing plate 92 are meshed again for transmission, so that the switched polishing plate 92 is driven to rotate in sequence by a single set of polishing motors 95, thereby reducing the investment in equipment and reducing costs.

[0041] Please refer to the attached Figure 8 The bottom end of the support frame 94 is fixedly connected to the limiting ring 22 , the rotating shaft 91 passes through the limiting ring 22 , and the bottom end of the grinding plate 92 is fixedly provided with a counterweight block 17 .

[0042] Specifically, the bottom end of the support frame 94 is limited by the limit ring 22 to avoid or reduce the shaking of the support frame 94 during grinding. The counterweight block 17 is used to apply downward gravity to the grinding plate 92 so that the idle grinding plate 92 remains vertical, which is convenient for rotating and switching the grinding plate 92.

[0043] Please refer to the attached Figure 2 A telescopic baffle 18 is fixedly provided on the opposite side of the two support arms 5, and a telescopic baffle 2 19 is fixedly provided between the support arm 5 and the inner arm of the bracket 2.

[0044] Specifically, the telescopic baffle 18 and the telescopic baffle 2 19 can automatically extend and shield the debris during grinding according to the lifting and lowering of the support arm 5 to prevent the debris from entering the interior of the bidirectional electric slide 4.
