Description

Technical Field

[0001] This utility model relates to the field of transportation operation technology, and in particular to a polishing module and a dual-unit polishing device. Background Technology

[0002] After the edges of the board are sealed, polishing equipment is needed to polish the upper and lower surfaces of the board. Generally, polishing equipment includes an upper polishing wheel for polishing the upper surface of the board and a lower polishing wheel for polishing the lower surface of the board.

[0003] Each polishing wheel is equipped with a corresponding longitudinal telescopic cylinder to drive the corresponding polishing wheel to move vertically closer to or away from the material. When polishing is required, the two longitudinal telescopic cylinders extend synchronously, and the upper and lower polishing wheels simultaneously come into contact with the material and perform the polishing operation; after polishing is completed, the two longitudinal telescopic cylinders retract synchronously, and the upper and lower polishing wheels simultaneously move away from the material to facilitate unloading.

[0004] During the polishing process described above, once the upper and lower polishing wheels are in close contact with the board, they can only rotate relative to the board (the board will be conveyed forward during the polishing process, so the polishing wheel and the board will be relatively displaced along the length of the board), and cannot move laterally relative to the board (that is, the polishing wheel will not move along the width of the board during the rotating polishing process). Therefore, the board can only be polished longitudinally (that is, along the length of the board), and cannot be polished laterally, resulting in a poor polishing effect.

[0005] Therefore, existing polishing equipment needs to be improved to solve the problem that it only polishes the board longitudinally and does not polish the board laterally, resulting in poor polishing effect.

[0006] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] One objective of this invention is to provide a polishing module and a dual-unit polishing device that can effectively solve the problem that existing polishing equipment only performs longitudinal polishing on the board and does not perform transverse polishing, resulting in poor polishing effect.

[0008] To achieve the above objectives, on the one hand, this utility model provides a polishing module, including two polishing wheel groups arranged opposite to each other, and two vertical linear drive mechanisms arranged in a one-to-one correspondence with the two polishing wheel groups. The two vertical linear drive mechanisms are used to cooperate with each other to drive the two polishing wheel groups to move closer to each other or further away from each other in the vertical direction.

[0009] The polishing wheel set includes:

[0010] A polishing wheel body, wherein the central axis of the polishing wheel body extends horizontally;

[0011] A polishing motor, wherein the drive end of the polishing motor is connected to the polishing wheel body for driving the polishing wheel body to rotate around the central axis;

[0012] A transverse linear drive mechanism, the drive end of which is connected to the polishing motor, is used to drive the polishing wheel body to reciprocate linearly relative to the plate in a direction parallel to the central axis.

[0013] Optionally, the vertical linear drive mechanism includes a vertical lead screw and a vertical motor that drives the vertical lead screw to rotate.

[0014] Optionally, the lateral linear drive mechanism is a two-section telescopic structure.

[0015] One extension section is used to drive the polishing wheel body to move closer to or away from the plate, and the other extension section is used to drive the polishing wheel body to reciprocate linearly relative to the plate.

[0016] Optionally, the lateral linear drive mechanism includes:

[0017] Cylinder block;

[0018] A drive rod, one end of which is connected to the polishing motor, and the other end of which extends into the cylinder body;

[0019] Two spaced-apart piston plates are located inside the cylinder body, which sequentially divide the internal space of the cylinder body into a first chamber, a second chamber, and a third chamber.

[0020] Optionally, the lateral linear drive mechanism further includes:

[0021] An obstacle avoidance solenoid valve, wherein the obstacle avoidance solenoid valve is connected to the first chamber and the third chamber;

[0022] A polishing solenoid valve, which is connected to the second chamber and the third chamber.

[0023] Optionally, the lateral linear drive mechanism further includes:

[0024] A first connector, the first connector connecting the first chamber to an inlet / outlet of the clearance solenoid valve;

[0025] The second connector connects the third chamber to another air inlet / outlet of the clearance solenoid valve;

[0026] A third connector, wherein the third connector connects the second chamber to an inlet / outlet of the polishing solenoid valve;

[0027] The fourth connector connects the third chamber to another inlet / outlet of the polishing solenoid valve.

[0028] Optionally, the third connector and the fourth connector are located between the first connector and the second connector, and the partition for separating the second chamber and the third chamber reciprocates between the third connector and the fourth connector.

[0029] Optionally, a spray cleaning mechanism is also provided for spraying cleaning agent onto the polishing wheel body.

[0030] On the other hand, a dual-unit polishing device is provided, including a central support and two polishing modules arranged on both sides of the central support.

[0031] Optionally, during polishing operations, the lateral linear drive mechanisms of the two polishing modules drive in opposite directions.

[0032] The beneficial effects of this utility model are as follows: It provides a polishing module and a dual-unit polishing device. When polishing a sheet material is required: first, the side of the sheet material attached to the module is fed between the two polishing wheel sets; then, two vertical linear drive mechanisms cooperate to drive the two polishing wheel sets closer together to polish the sheet material; next, a polishing motor drives the polishing wheel body to rotate around the central axis, thereby polishing the sheet material longitudinally. Simultaneously, a horizontal linear drive mechanism drives the polishing wheel body to reciprocate linearly relative to the sheet material in a direction parallel to the central axis, thereby polishing the sheet material laterally. That is, during the polishing process, the polishing wheel body not only rotates relative to the sheet material but also reciprocates laterally relative to the sheet material under the drive of the horizontal linear drive mechanism, thereby achieving simultaneous longitudinal and horizontal polishing of the sheet material.

[0033] Therefore, the polishing module and dual-unit polishing equipment provided by this utility model can effectively solve the problem that existing polishing equipment only performs longitudinal polishing on the board and does not perform transverse polishing on the board, resulting in poor polishing effect.

[0053] This utility model provides a polishing module and a dual-unit polishing device, which is suitable for polishing applications of edge-sealed boards. It can effectively solve the problem that existing polishing equipment only polishes the board longitudinally and does not polish the board laterally, resulting in poor polishing effect.

[0054] See Figure 1 and Figure 2 The dual polishing device provided in this embodiment includes a middle support 100 and two polishing modules 200 arranged on both sides of the middle support 100.

[0055] The polishing module 200 includes two polishing wheel sets 200a arranged vertically opposite each other, and two vertical linear drive mechanisms 200b arranged in a one-to-one correspondence with the two polishing wheel sets 200a. The two vertical linear drive mechanisms 200b are used to cooperate with each other to drive the two polishing wheel sets 200a to move closer to each other or further away from each other in the vertical direction.

[0056] Optionally, the vertical linear drive mechanism 200b is a motor lead screw assembly, that is, it includes a vertical lead screw 1 and a vertical motor 2 that drives the vertical lead screw 1 to rotate. When the vertical motor 2 drives the vertical lead screw 1 to rotate, the corresponding polishing wheel set 200a will slide up and down. The two polishing wheel sets 200a slide in opposite directions, allowing them to move closer to or further apart from each other. Compared to the traditional method of manually adjusting the lead screw to adjust the position, the longitudinal movement of the polishing motor 2 can be achieved by individually controlling the vertical position of the polishing wheel set 200a through the motor, offering high freedom and convenient adjustment.

[0057] The polishing wheel assembly 200a includes a polishing wheel body 5, a polishing motor 4, and a transverse linear drive mechanism 3. The central axis of the polishing wheel body 5 extends horizontally; the drive end of the polishing motor 4 is connected to the polishing wheel body 5 for driving the polishing wheel body 5 to rotate around the central axis; the drive end of the transverse linear drive mechanism 3 is connected to the polishing motor 4 for driving the polishing wheel body 5 to reciprocate linearly relative to the plate 300 in a direction parallel to the central axis.

[0058] The polishing module 200 and dual-unit polishing equipment provided in this embodiment, when polishing a sheet material 300 is required: first, the side of the sheet material 300 attached to it is fed between the two polishing wheel sets 200a; then, the vertical linear drive mechanism 200b drives the two polishing wheel sets 200a to move closer together to polish the sheet material 300; then, the polishing motor 4 drives the polishing wheel body 5 to rotate around the central axis, thereby polishing the sheet material 300 longitudinally. Simultaneously, the transverse linear drive mechanism 3 drives the polishing wheel body 5 to reciprocate linearly relative to the sheet material 300 in a direction parallel to the central axis, thereby polishing the sheet material 300 laterally. That is, during the polishing process, the polishing wheel body 5 not only rotates relative to the sheet material 300, but also reciprocates laterally relative to the sheet material 300 under the drive of the transverse linear drive mechanism 3, thereby achieving simultaneous longitudinal and transverse polishing of the sheet material 300.

[0059] Therefore, the polishing module 200 and the dual polishing equipment provided by this utility model can effectively solve the problem that the existing polishing equipment only performs longitudinal polishing on the plate 300 and does not perform transverse polishing on the plate 300, resulting in poor polishing effect.

[0060] In this embodiment, the transverse linear drive mechanism 3 is a two-section telescopic structure. One section is used to drive the polishing wheel body 5 to move closer to or away from the plate 300, and the other section is used to drive the polishing wheel body 5 to reciprocate linearly relative to the plate 300.

[0061] See Figure 3 Specifically, the transverse linear drive mechanism 3 includes a cylinder body 301, a drive rod 302, two spaced piston plates 303, an avoidance solenoid valve 304, a polishing solenoid valve 305, a first connector 306, a second connector 307, a third connector 308, and a fourth connector 309.

[0062] One end of the drive rod 302 is connected to the polishing motor 4, and the other end extends into the cylinder body 301; the two piston plates 303 are located inside the cylinder body 301, dividing the internal space of the cylinder body 301 into a first chamber 3011, a second chamber 3012, and a third chamber 3013 in sequence.

[0063] The avoidance solenoid valve 304 is connected to the first chamber 3011 and the third chamber 3013; the polishing solenoid valve 305 is connected to the second chamber 3012 and the third chamber 3013.

[0064] The first connector 306 connects the first chamber 3011 to one inlet / outlet of the avoidance solenoid valve 304; the second connector 307 connects the third chamber 3013 to the other inlet / outlet of the avoidance solenoid valve 304. The third connector 308 connects the second chamber 3012 to one inlet / outlet of the polishing solenoid valve 305; the fourth connector 309 connects the third chamber 3013 to the other inlet / outlet of the polishing solenoid valve 305.

[0065] The third connector 308 and the fourth connector 309 are located between the first connector 306 and the second connector 307, and the partition for separating the second chamber 3012 and the third chamber 3013 reciprocates between the third connector 308 and the fourth connector 309.

[0066] Initially, the polishing module 200 is not located directly above the plate 300, but rather on its outer side. When polishing is required, the vertical linear drive mechanism 200b drives the two polishing wheel sets 200a closer together until the height of the polishing wheel body 5 is sufficient to contact the plate 300. Then, the control solenoid valve 304 supplies air to the first chamber 3011 through the first connector 306, causing the piston plate 303 to extend the drive rod 302 forward, thereby moving the polishing wheel body 5 along the central axis to directly above the plate 300. Finally, the polishing motor 4 drives the polishing wheel body 5 to rotate around the central axis... The axis rotates, thus longitudinally polishing the plate 300. Simultaneously, the polishing solenoid valve 305 alternately supplies air to the second chamber 3012 and the third chamber 3013, thereby driving the polishing wheel body 5 to reciprocate linearly in a direction parallel to the central axis, thus performing transverse polishing on the plate 300. After the polishing operation is completed, the control avoidance solenoid valve 304 supplies air to the third chamber 3013 through the second connector 307, causing the piston plate 303 to drive the drive rod 302 to retract backward, thereby causing the polishing wheel body 5 to move along the central axis to the side position of the plate 300, exiting the polishing operation area and detaching from the plate 300.

[0067] Optionally, during polishing operations, the lateral linear drive mechanisms 3 of the two polishing modules 200 are driven in opposite directions. That is, as shown... Figure 3As shown, when the polishing solenoid valve 305 of the transverse linear drive mechanism 3 of one polishing module 200 supplies air to the corresponding second chamber 3012, causing the drive rod 302 to extend the polishing wheel body 5, the polishing solenoid valve 305 of the transverse linear drive mechanism 3 of the other polishing module 200 supplies air to the corresponding third chamber 3013, causing the drive rod 302 to retract the polishing wheel body 5. The two polishing wheel bodies 5 are staggered, which helps to improve the uniformity of the polishing effect when the two polishing modules 200 work together. After the polishing operation is completed, the clearance solenoid valves 304 of the two polishing modules 200 simultaneously supply air to their respective third chambers 3013, so that the two polishing wheel bodies 5 detach from the plate 300 together.

[0068] Optionally, the polishing module 200 is further provided with a spraying cleaning mechanism for spraying cleaning agent onto the polishing wheel body 5. Furthermore, spraying cleaning mechanisms can be added above the upper polishing wheel and below the lower polishing wheel respectively to spray cleaning agent onto the corresponding polishing wheel body 5, which helps reduce the number of times the polishing wheel body 5 needs to be disassembled and cleaned, ensuring polishing effect and extending the service life of the polishing wheel body 5.

[0069] In this embodiment, the host computer can select whether to turn on the polishing wheel cleaning function. The number of times the limit switch at the feed port of the equipment is turned on and off is used to calculate the number of times the board is cleaned. After the number of times the board is cleaned reaches the set value, the cleaning agent is sprayed for a certain period of time. The set value of the number of times the board is cleaned and the spraying time of the cleaning agent can be adjusted independently.

[0070] In summary, the polishing module 200 and the dual-stage polishing equipment provided in this embodiment have the following advantages:

[0071] ① Bidirectional polishing: This equipment can simultaneously polish 300mm plates in both longitudinal and transverse directions, effectively solving the problem that existing polishing equipment can only perform unidirectional polishing, thus improving the uniformity and quality of the polishing effect.

[0072] ② Cleaning function: Equipped with a spray cleaning mechanism, it can clean the polishing wheel body 5 in a timely manner, ensuring the polishing effect and extending the service life of the polishing wheel body 5.

[0073] ③ Autonomous adjustment: The host computer can be used to adjust the set value of the number of times the board is sprayed and the spraying time of the cleaning agent to adapt to different production needs.

[0074] ④ Uniform polishing: The horizontal linear drive mechanism 3 of the two polishing modules 200 drives in opposite directions, which helps to improve the uniformity of the polishing effect.

[0075] ⑤Safe and reliable: By controlling the solenoid valve 304 and the polishing solenoid valve 305, the polishing wheel body 5 is kept at a safe distance from the plate 300 when not in operation, thus avoiding accidental damage.

[0076] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
