Description

A double-sided reversible multi-head polishing machine

【Technical field】

【Background technique】

Polishing refers to the use of mechanical, chemical or electrochemical effects to reduce the surface roughness of workpieces (such as glass sheets, mobile phone screens, etc.) to obtain a bright and smooth surface. It uses flexible polishing tools and abrasive particles or other polishing methods. The medium modifies the surface of the workpiece. The polishing machine is a kind of electric tool used for polishing. It consists of basic components such as a base, a material tray, a polishing fabric, and a motor. The polishing fabric usually uses a sponge blanket, which is made of wool or wool-like sponge material. The function of removing marks and brightening can also be used as one of the combined polishing wheels to eliminate the shallow surface scratches of the glass. It is used together with the polishing powder coolant. The rotation of the sponge blanket is powered by the motor; the material tray is used to place the workpiece The turntable is set up and down with the sponge blanket and the distance is usually set to the thickness of the workpiece. The material disc can be rotated freely by applying external force. Several vacuum holes are set on the material disc. The polished surface of the workpiece faces the sponge blanket and the entire workpiece is absolutely Parallel and evenly pressed lightly on the material tray and fixed by vacuum adsorption. When the polishing machine is working, the sponge blanket is powered by the motor and rotates at a constant speed. There is a certain speed difference between it and the material tray carrying the workpiece. The sponge blanket rotates faster than the material tray. The workpiece on the disc produces a certain amount of friction to achieve the purpose of polishing.

In order to improve efficiency, technicians invented a double-head polishing machine, that is, two polishing heads are set on one polishing machine to operate at the same time, whether it is single-head or double-head polishing. The overall polishing process of the machine is like this: before polishing, the workpiece is placed on the material tray by manual loading, and the polishing machine starts to polish after the material is unloaded. For polished workpieces, the polishing machine is in a standby state during the process of taking and loading materials, so that the entire production process is intermittent and the efficiency is very low.

At the same time, using the turning cylinder 1037 to drive the rack 1035 to realize the rotation of the polishing head 1011 through gear transmission is more reliable and more efficient than the traditional use of motors to provide power to realize turning.

The adjustment structure 103 further includes a first bracket 1039, which is located below the turning cylinder 1037. The first bracket 1039 includes a cross bar 1034 and a vertical bar 1036. The vertical bar 1036 is connected and matched with the stretching cylinder 1053 arranged in the base 107. , to adjust the height of the first polishing group 101 . At the same time, a fixed clip 1038 is respectively arranged on each vertical rod 1036, and the fixed clip 1038 is used to limit the displacement of the vertical rod 1036. Since the stretching cylinder 1053 may have a certain error when controlling the vertical rod 1036, it is therefore provided The fixed clip 1038 is locked at the lowest position of its descent. The fixed clip 1038 acts as a limiter so that the vertical bar 1036 cannot slide down after falling to a certain distance, so as to ensure the gap between the first polishing group 101 and the second polishing group 107. The distance is within the allowable polishing range of the workpiece to prevent damage to the workpiece caused by excessive polishing and improve the yield of polished workpieces.

The adjustment structure 103 further includes a second support 1032, which is arranged on both sides of the thin rod 1031 corresponding to the first support 1039, and is used to cooperate with the first support 1039 to lift and turn the first polishing group 101. The second bracket 1032 includes a shaft sleeve 1030. The difference between the second bracket 1032 and the first bracket 1039 is that the shaft sleeve 1030 is sleeved on one end of the thin rod 1031 and the two can move relatively flexibly, that is, the two For flexible connection, a plug (not labeled) is provided on the left side of the thin rod 1031 to prevent the second bracket 1032 from falling off from the left side of the thin rod 1031 .

As a modified implementation manner, the adjustment structure 103 may be any structure for rotating the first polishing group 101 and adjusting its height. For example, the adjustment structure 103 is a suspended structure, which is suspended at a high place by a rope or other means to adjust the first polishing group 101 connected thereto. Or, other devices that can support the thin rod 1031 and the turning cylinder 1037 and adjust their heights are arranged beside the base 107 .

When in use, first adjust the multi-head polishing machine 10 that can be reversed on both sides, so that it is in the initial state, adjust the height of the bracket 155 so that the first polishing group 101 has enough room to rotate, and at the same time clamp the fixing clip 1038 on the vertical bar 1036 Appropriate position, make the two polishing heads 1011 of the first polishing group 101 be in vertical direction, and workpiece is placed on the material disk 1023 that is positioned at above, each workpiece completely covers corresponding vacuum pad 1024, at this moment vacuum The vacuum groove 1022 in the gasket 1024 absorbs the workpiece, and its attractive force is much greater than the gravity of the workpiece, preventing the workpiece from slipping. Then put polishing agent, water, etc. on the second polishing group 107 to mix them evenly.

After the feeding is finished, the control system 109 controls the turning cylinder 1037 to work, and the turning cylinder 1037 pulls the rack 1035, and the rack 1035 and the gear 1033 cooperate to drive the thin rod 1031 to start rotating through the principle of gear transmission, thereby driving the first polishing group 101 to turn over. The polishing head 1011 loaded with the workpiece rotates to the bottom and corresponds to the large plate 1071. At this time, the operator can continue to put the workpiece on the material tray 1023 of another polishing head 1011, and the stretching cylinder 1053 in the base 107 starts to start simultaneously. The first support 1039 and the second support 1032 descend synchronously downwards, and stop at the position clamped by the clamp 1038. At this moment, the distance between the material tray 1023 and the large plate 1071 is only the thickness of the workpiece, and the surface to be polished of the workpiece and the sponge blanket 1073 Lightly touch the surface. The motor reducer 1055 starts to drive the large plate 1071 of the second polishing group 107 to rotate, thereby driving the sponge blanket 1073 to rotate. At the same time, the independent motor 1015 arranged on the first polishing group 101 drives the material disc 1023 of the polishing head 1011 on the side in contact with the sponge blanket 1073 to rotate, and the rotational direction of the material disc 1023 is opposite to that of the large disc 1071 , that is, the polishing workpiece and the sponge blanket 1073 rotate in opposite directions, which can further save the time required for workpiece polishing and improve polishing efficiency. After the polishing is finished, the motor reducer 1055 is closed, and the stretching cylinder 1053 makes the first support 1039 and the second support 1032 rise to the initial position synchronously. The polishing head 1011 is turned from bottom to top, and the polishing head 1011 carrying the workpiece to be polished is rotated to the bottom to start a new round of polishing process. At the same time, the operator removes the polished workpiece and puts it into the workpiece to be polished. In this way, the circle is rotated again and again, and the polishing is carried out round after round.

Further, each material disc 1023 in the polishing head 1011 is driven to rotate by an independent motor 1015, and the large disc 1071 is driven to rotate by the motor reducer 1055. On the contrary, the relative movement of the two causes the workpiece on the material tray 1023 to produce reverse friction, the friction force is multiplied, and the polishing effect obtained by single rotation friction is more obvious, thereby achieving the purpose of rapid polishing and improving polishing efficiency.

2. By setting the vacuum groove 1022 on the material vacuum gasket 1024 in the shape of an "H" groove, the vacuum adsorption area is larger and the adsorption capacity is stronger, so that the workpiece is more firmly adsorbed on the material tray 1023 After the workpiece is polished, the vacuum tank 1022 can gently blow up the workpiece while releasing the pressure, so as to facilitate the pick-up of the workpiece.

3. A circle of baffles 1027 with a certain height is arranged on the edge of the circular groove 1021 to prevent the mixture of the polishing machine and water from splashing around when the large plate 1071 is rotating, thereby ensuring cleanliness.

4. By arranging the first support 1039 and the second support 1032, the two polishing heads 1011 can be raised and lowered and have enough turning space, since the material disc 1023 is rotated to be opposite to the sponge blanket 1073, the distance between the two is the distance of the workpiece Thickness, then through the adjustment of the liftable first bracket 1039 and the second bracket 1032, this kind of reversible double-sided multi-head polishing machine 10 is suitable for workpieces of different thicknesses.

5. The base 105 is equipped with a motor reducer 1055. Compared with the traditional setting where an independent main motor is matched with an independent reducer, the transmission efficiency of the motor reducer 1055 is 40% higher than that of the traditional reducer, and it has stable deceleration performance. Low noise, energy saving, easy maintenance and so on.

6. Using the turning cylinder 1037 to drive the rack 1035 to realize the rotation of the polishing head 1011 through gear transmission is more reliable and efficient than using a motor to provide power to realize turning.

7. The height of the vertical rod 1036 on the base 107 is limited by setting the fixing clip 1038. Since the cylinder cannot control the vertical rod 1036 accurately when lifting and lowering the vertical rod 1036, the lowest position of the vertical rod 1036 is fixed by setting the fixing clip 1038. The fixing clip 1038 acts as a limiter to ensure that the distance between the first polishing group 101 and the second polishing group 107 is within the allowable polishing range of the workpiece, so as to prevent excessive polishing from causing damage to the workpiece and improve the yield of the polished workpiece.
