Description

Technical Field

[0001] The invention relates to a rounded corner polishing device, in particular to a rounded corner polishing device for a wooden board applied in the technical field of board polishing. Background Art

[0002] Boards are flat rectangular building material boards made of standard sizes, which are used in the construction industry as components of walls, ceilings or floors. The board production process needs to go through multiple steps. In order to improve the aesthetics of the board, it is usually polished at the end to increase the brightness of the board. For some mid-to-high-end boards, the corners are designed to be rounded to improve the overall aesthetics. When setting the rounded corners, the corners of the original wood are usually cut and then polished. In the existing technology, the rounded corner polishing operation is mainly performed by workers holding polishing equipment. This method is inefficient and has unstable quality. It is difficult to meet the uniformity and stability of mid-to-high-end board production.

[0030] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1-Figure 8 A rounded corner polishing device for a wooden board is shown, comprising: a base 1, a slide rail mechanism 4, a clamping mechanism, a polishing mechanism 2, and a polishing intelligent controller 3. The slide rail mechanism 4 is installed on the base 1, and a tray 5 is installed on the base 1.

[0033] The clamping mechanism includes two clamping units, and the two clamping units are respectively located at two vertical sides of the tray 1 5. The clamping unit includes a plurality of clamping assemblies 10, and the plurality of clamping assemblies 10 are stacked in the vertical direction. The clamping assembly 10 includes a clamping support shell 29, and an air bag 20 and an air source 19 are installed on the inner wall of the clamping support shell 29. The air bag 20 is connected to the air source 19 through an air guide tube 22. The air bag 20 is fixedly connected to a push plate 27, and a pressure sensor 28 is arranged on the push plate 27.

[0034] The polishing mechanism 2 is installed on the slide rail mechanism 4, and the polishing mechanism 2 includes a polishing support shell 30, a tray 9 fixed on the polishing support shell 30, a limiting groove 14 opened at the upper end of the polishing support shell 30, and a polishing roller 13 plugged into the limiting groove 14;

[0035] The polishing intelligent controller 3 is arranged on one side of the base 1, and the polishing intelligent controller 3 includes a master control module, a command module, and a detection module. The command module is electrically connected to the master control module, the slide rail mechanism 4, the polishing mechanism 2, and the air source 19 respectively, and the detection module is electrically connected to the master control module, the polishing mechanism 2, and the pressure sensor 28 respectively.

[0036] After the operator stacks the wooden boards on the pallet 1 5, the wooden boards are placed close to the clamping mechanism. The output end of the slide rail mechanism 4 is connected to the pallet 2 9. The slide rail mechanism 4 includes a longitudinal slide rail 16 and a transverse slide rail 15. The longitudinal slide rail 16 is fixedly connected to the base 1, and the transverse slide rail 15 is fixedly connected to the polishing mechanism 2. The longitudinal slide rail 16 is slidably connected to the transverse slide rail 15. The slide rail mechanism 4 can move independently in the transverse and longitudinal directions, and can also move arbitrarily in a plane at the same time. Since the wooden boards are stacked, there are certain requirements on the bearing capacity of the slide rail mechanism 4. Therefore, the longitudinal slide rail 16 and the transverse slide rail 15 both include a driving slide rail 17 and an auxiliary slide rail 18. The driving slide A driving member 3 is installed on the rail 17 to control the operation of the driving slide rail 17. The driving slide rail 17 is installed in parallel with the auxiliary slide rail 18, which can improve the stability of the slide rail mechanism 4 without affecting its movement performance. The master control module controls the slide rail mechanism 4 through the instruction module to drive the pallet 2 9 to move toward the pallet 1 5. Universal wheels 12 are provided on the pallet 1 5 and the pallet 2 9. When the pallet 2 9 moves, the universal wheels 12 can effectively reduce the friction between the pallet 1 5 and the pallet 2 9 and the wooden board, and reduce the damage to the surface of the wooden board. After the pallet 2 9 moves a certain distance, the wooden board is initially clamped. The clamping mechanism includes two clamping units, and the two clamping units are respectively located on the pallet 1 5 and the pallet 2 9. At two vertical sides of 5, the clamping unit includes a plurality of clamping assemblies 10, and the plurality of clamping assemblies 10 are stacked in the vertical direction, the clamping assembly 10 includes a clamping support shell 29, an airbag 20 and an air source 19 are installed on the inner wall of the clamping support shell 29, the airbag 20 is connected with the air source 19 through an air guide tube 22, the airbag 20 is fixedly connected with a push plate 27, a pressure sensor 28 is arranged on the push plate 27, the pressure sensor 28 is electrically connected with the detection module, and the air source 19 is electrically connected with the command module, at this time, the command module controls the air source 19 to pre-inflate the airbag 20, pushes the push plate 27 of the clamping assembly 10, further clamps the wooden board, and the detection module pushes the push plate 27 The pressure sensor 28 on the upper part measures the pressure between each wooden board and the polishing roller 13, makes a record and sends the information to the main control module, which compares the measured pressure with the specified pressure (the set pressure for polishing different boards is preset in the main control module). If the measured pressure is much smaller than the specified pressure (much smaller means that the difference between the two is greater than the set pressure difference between the measured pressure and the specified pressure preset in the main control module), the instruction module controls the slide mechanism 4 to drive the tray 2 9 to continue to approach the tray 1 5, until the main control module receives the measured pressure information sent by the detection module and the specified pressure is within a difference range, and the main control module controls the slide mechanism 4 to stop moving through the instruction module;If the measured pressure is much greater than the specified pressure (much greater means that the difference between the two is greater than the set pressure difference between the measured pressure and the specified pressure preset in the master control module), the instruction module controls the slide rail mechanism 4 to drive the tray 2 9 away from the tray 1 5 until the master control module receives the measured pressure information sent by the detection module and the specified pressure is within a difference range, and the master control module controls the slide rail mechanism 4 to stop moving through the instruction module. ;

[0037] When the measured pressure information sent by the detection module received by the master control module is slightly less than the specified pressure (slightly less than means that the difference between the two is less than the set pressure difference between the measured pressure and the specified pressure preset in the master control module), the air source 19 is controlled by the instruction module to inflate the airbag 20, so that the airbag 20 is inflated and the push plate 27 is pushed outward, until the measured pressure sent by the detection module received by the master control module is within a certain error range, and the air source 19 is controlled by the instruction module to stop inflating the airbag 20; if the measured pressure information sent by the detection module received by the master control module is slightly greater than (slightly greater than means that the difference between the two is less than the set pressure difference between the measured pressure and the specified pressure preset in the master control module), the air source 19 is controlled by the instruction module to stop inflating the airbag 20. When the measured pressure is less than the set pressure difference between the measured pressure and the specified pressure preset in the master control module), the air source 19 is controlled by the command module to make the airbag 20 release part of the gas and pull the push plate 27 back inward. When the measured pressure is slightly less than the specified pressure (slightly less means that the difference between the two is less than the set pressure difference between the measured pressure and the specified pressure preset in the master control module), the airbag 20 is inflated and the push plate 27 is pushed outward. After the master control module receives the measured pressure sent by the detection module and the specified pressure is within a certain error range, the air source 19 is controlled by the command module to stop inflating the airbag 20.

[0038] After the pressure between the push plate 27 and the polishing roller 13 is adjusted to within the error range, the polishing mechanism 2 is started for polishing. The polishing mechanism 2 is installed on the slide rail mechanism 4, and the output shaft of the driving member 6 is installed with the polishing roller 13. The output shaft of the driving member 6 drives the polishing roller 13 to rotate. The top of the polishing support shell 30 is installed with a driving member 2 7, and the output shaft of the driving member 2 7 is installed with a driving rod 8. The other end of the driving rod 8 is installed with a driving member 6. The driving member 2 7 and the driving member 6 are both electrically connected to the instruction module. The main control module first controls the driving member 6 to start through the instruction module, and then controls the driving member 2 7 to start. A limiting groove 14 is provided at the upper end of the polishing support shell 30. The driving member 2 7 drives the driving member 6 and the polishing roller 13 to make a circular arc reciprocating motion along the limiting groove 14 through the driving rod 8 to polish the rounded corners of the wooden board. A bearing 23 is provided at the top of the polishing roller 13 corresponding to the limiting groove 14. The bearing 23 and the limiting groove 14 is rollingly connected, and the bearing 23 can reduce the friction between the top of the polishing roller 13 and the inner wall of the limit groove 14, thereby improving the polishing accuracy. A reflection sensor 11 is installed on the inner wall of the polishing support shell 30, and the reflection sensor 11 is electrically connected to the detection module. After the polishing mechanism 2 polishes the wooden board for a period of time, the main control module receives the reflection degree information of the rounded corner of the wooden board sent by the reflection sensor 11 to detect the reflection degree of the wooden board, so as to judge the polishing degree. When the polishing degree meets the standard (the main control module has preset the specified polishing degree for polishing different boards), the instruction module controls the driving member 2 7 to return to the initial position and stop, and then controls the driving member 1 6 to stop moving, and then controls the air source 19 of the clamping assembly 10 to make the air bag 1 20 release gas at the same time, and finally controls the slide rail mechanism 4 to drive the tray 2 9 away from the tray 1 5 by a certain distance. At this time, the operator changes the direction of the board with a rounded corner polished and polishes other rounded corners.

[0039] The second implementation method:

[0040] Figure 6-Figure 8 A rounded corner polishing device for a wooden board is shown. Different from the first embodiment, considering that the clamping assembly 10 only uses an airbag 20 to control the polishing pressure of the wooden board, the airbag 20 may have a certain elasticity after being inflated. When the pressure of the polishing roller 13 on the wooden board is applied to the clamping assembly 10 during the polishing process, the airbag may shrink or deform. Therefore, a locking assembly is installed in the clamping assembly 10 so that the push plate 27 can be locked in position after being extended, thereby further improving the rounded corner polishing accuracy of the board.

[0041] A locking assembly is installed on the inner wall of the clamping support shell 29, and the locking assembly includes a ratchet rail 24, a ratchet bar 25, a pawl 26, and an airbag 21. The ratchet rail 24 is slidably connected to the ratchet bar 25, and a pawl 26 is correspondingly installed below the ratchet bar 25. An airbag 21 is arranged below the pawl 26. The airbag 21 is connected to the air source 19 through the air guide tube 22, and the ratchet bar 25 is fixedly connected to the push plate 27. When the clamping assembly 10 is required to control the polishing pressure between the wooden board and the polishing roller 13, the master control module sends an instruction to the air source 19 through the instruction module to control the air source 19 to inflate the airbag 1 20 and the airbag 2 21 at the same time, and the airbag 1 20 The airbag 21 is inflated to push out the push plate 27 and the ratchet bar 25, and the airbag 21 is inflated to lift up the pawl 26 so that it is stuck in the tooth gap of the ratchet bar 25. The push plate 27 drives the ratchet bar 25 to move outward, and the pawl 26 slides over the back of the teeth of the ratchet bar 25 without affecting its movement. After the polishing pressure is adjusted, the airbag 21 is inflated again to fix the pawl 26 in the tooth gap of the ratchet bar 25. After polishing starts, the polishing roller 13 applies a certain pressure to the wooden board, and the wooden board transfers the pressure to the ratchet bar 25, but at this time the pawl 26 has been inserted into the tooth gap of the ratchet bar 25, so that it cannot retract, further improving the polishing accuracy of the board fillet.

[0042] When polishing is completed, the master control module controls the slide rail mechanism 4 through the instruction module to drive the tray 2 9 to move to a position away from the tray 1 5. At this time, the gas source 19 is controlled to release the gas in the airbag 1 20 and the airbag 2 21. After the gas in the airbag 21 is released, the pawl 26 loses its support and falls back to its original position. At the same time, after the gas in the airbag 1 20 is released, it drives the push plate 27 to reset. Since the pawl 26 falls back to its original position, there is no resistance to the inward movement at this time, and it is driven by the push plate 27 to return to the initial position.

[0043] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
