Description

Technical Field

[0001] The present invention relates to the technical field of decorative board processing, and particularly relates to a device for laser detection and automatic grinding of rough edges of decorative boards. Background Art

[0002] With the booming development of the decoration and fitment industry, the application of decorative boards is becoming increasingly widespread, and the quality requirements for them are also continuously improving. During the production and processing of decorative boards, rough edges are likely to occur on the edges of the boards, which not only affects the aesthetics of the boards but also may pose potential safety hazards in subsequent use. The traditional manual detection and grinding methods are inefficient and inaccurate, making it difficult to meet the requirements of large-scale industrial production. Laser detection technology, with its advantages such as high precision and non-contact, shows good application prospects in the field of rough edge detection of boards. Combining laser detection with automatic grinding technology, a device that can quickly and accurately detect the rough edges of decorative boards and automatically complete the grinding process has become an important direction for improving the production quality and efficiency of decorative boards, and is of great significance for promoting the automation and intelligent development of the decorative board processing industry.

[0003] During the process of grinding the rough edges of decorative boards, a large amount of debris is generated. The debris generated during grinding remains on the surface of the board or on the grinding roller. On the one hand, it will cause uneven contact between the grinding roller and the board, resulting in a decrease in grinding precision, being unable to effectively remove the rough edges, and affecting the finished product quality of the decorative board. On the other hand, the accumulation of debris will hinder the normal operation of the grinding roller and reduce the grinding efficiency. In addition, the surfaces of the laser source and the photodetector of the laser detection mechanism are easily contaminated with impurities such as debris and dust. These impurities will change the propagation path and reflection characteristics of the laser, resulting in deviations in the detection signal, an increase in errors, inaccurate detection results, being unable to accurately identify the position and size of the rough edges, and thus affecting the accuracy and effect of automatic grinding, resulting in problems such as over-grinding or under-grinding. Summary of the Invention

[0004] The purpose of the present invention is to: solve the problems that the waste debris of the existing device for laser detection and automatic grinding of rough edges of decorative boards is not easy to clean, resulting in a decrease in grinding precision, and the grinding debris impurities will change the propagation path and reflection characteristics of the laser, resulting in deviations in the detection signal, an increase in errors, and inaccurate detection results, and propose a device for laser detection and automatic grinding of rough edges of decorative boards.

Specific implementation mode

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments 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 efforts shall fall within the protection scope of the present invention.

[0033] Refer to Figures 1-9 As shown in the figure, a device for laser detection and automatic grinding of the rough edges of decorative plates provided in this embodiment includes a base 1. A first lead screw slide 3 is arranged on the base 1 through a bracket 2. The output end of the first lead screw slide 3 is provided with a motor set 5 that moves linearly along its length direction through a mounting frame 4. The output end of the motor set 5 is detachably connected with a grinding roller 6. A workbench 8 is also arranged on the base 1. The workbench 8 can move along a path perpendicular to the moving direction of the motor set 5 through a second lead screw slide 10. A detection mechanism 9 for detecting the rough edges of the decorative plate is arranged on the base 1. The detection mechanism 9 can cooperate with the chip removal mechanism 7 to achieve self-cleaning during the grinding process. The detection mechanism 9 includes a photoelectric detector 91 arranged above the base 1 through a fixed frame 92, and a laser source 93 located on the photoelectric detector 91.

[0034] In the present invention, the decorative board to be detected and polished is fixed on the workbench 8 through a fixture. The edge of the board of the decorative board extends beyond the side of the workbench 8. Driven by the second screw slide 10, the workbench 8 can move along a path perpendicular to the moving direction of the motor set 5, so as to adjust the board to a suitable detection and polishing position. The laser source 93 of the detection mechanism 9 emits a laser beam, which irradiates the edge of the decorative board. When the laser beam irradiates the edge of the board, part of the light will be reflected back. The photoelectric detector 91 receives these reflected lights. If there are burrs on the edge of the board, the irregular shape of the burrs will cause changes in the characteristics of the reflected light, such as intensity and angle. The photoelectric detector 91 converts the received optical signal into an electrical signal and transmits it to the subsequent control system. The control system judges whether there are burrs on the edge of the board by analyzing the change of the electrical signal. According to the burr position information detected by the detection mechanism 9, the second screw slide 10 drives the workbench 8 to continue to move, so that the edge of the decorative board on the workbench 8 contacts the polishing roller 6. The motor set 5 on the mounting frame 4 is started to drive the polishing roller 6 to rotate at a high speed. The rotating polishing roller 6 contacts the burrs of the board and polishes the burrs through friction. During this process, the first screw slide 3 on the bracket 2 drives the mounting frame 4 to move, so that the polishing roller 6 moves along the burrs of the decorative board until the burrs are removed and the edge of the board meets the requirement of flatness.

[0035] Specifically, as Figures 2-4 shown, a chip removal mechanism 7 for collecting and cleaning the polishing waste chips on the polishing roller 6 is provided on the base 1. The chip removal mechanism 7 includes a box body 71 detachably mounted on the base 1. An air suction fan 72 is provided on the box body 71, and a filter screen 73 is provided inside the box body 71. A cover 75 located on one side of the polishing roller 6 is provided on the box body 71 through a hose 74 connected thereto.

[0036] Among them, when the air suction fan 72 is turned on, a negative pressure environment is formed inside the box body 71. Since the box body 71 is connected to the cover 75 through the hose 74, this negative pressure will be conducted to the opening of the cover 75. At this time, the cover 75 located on one side of the polishing roller 6 will generate suction force to suck in the waste chips generated during the polishing process. The waste chips enter the inside of the box body 71 through the cover 75 and the hose 74 along with the air flow. In the box body 71, the filter screen 73 separates the waste chips and the air. The waste chips are intercepted by the filter screen 73 and remain in the box body 71, while the filtered air is discharged from the box body 71 through the air suction fan 72, completing the entire cycle process of waste chip collection and cleaning. Through the negative pressure suction force, the chip removal mechanism 7 can timely and effectively collect the waste chips generated by the polishing roller 6 during the polishing of the decorative board, reduce the interference of the waste chips on the polishing roller 6 and the surface of the decorative board, enable the polishing roller 6 to contact the board more stably and evenly, ensure the polishing accuracy, and improve the finished product quality of the decorative board.

[0037] It should be noted that, as Figure 4 andFigure 5 As shown in the figure, a cleaning component 76 for cleaning the filter screen 73 is provided on the box body 71. The cleaning component 76 includes a connecting rod 761 that penetrates the top of the box body 71. At the bottom of the connecting rod 761, a cleaning cotton 763 that contacts the filtering surface of the filter screen 73 is provided through a mounting plate 762. The cleaning component 76 further includes a guide sleeve 764 provided on the top of the box body 71. The connecting rod 761 penetrates the guide sleeve 764 and is slidably connected thereto. A tensioning bolt 765 is provided on the guide sleeve 764.

[0038] Among them, when a large amount of waste chips adhere to the surface of the filter screen 73 after long-term use, affecting the filtering effect and the airflow passage, it can be cleaned. First, loosen the tensioning bolt 765 on the guide sleeve 764 to enable the connecting rod 761 to slide freely within the guide sleeve 764. Then, manually move the connecting rod 761 up and down to drive the bottom mounting plate 762 and the cleaning cotton 763 to perform a reciprocating wiping motion on the filtering surface of the filter screen 73. The cleaning cotton 763 is in close contact with the surface of the filter screen 73, and the waste chips adhering to the filter screen 73 are cleaned off through friction. After the cleaning is completed, tighten the tensioning bolt 765 to fix the position of the connecting rod 761 and prevent it from shaking during the operation of the device. By cleaning the waste chips accumulated on the filter screen 73 in time through the cleaning component 76, the blockage of the filter screen 73 is avoided, the smooth passage of the airflow in the box body 71 is ensured, and the suction of the chip removal mechanism 7 is maintained stable, so as to continuously and efficiently collect the grinding waste chips and ensure the long-term stable operation of the chip removal mechanism 7.

[0039] In addition, a collection box 712 is provided in a pull-out manner at the bottom of the box body 71. A handle 713 is provided on the collection box 712. A through port 711 communicating with the collection box 712 is opened on the partition inside the box body 71. During the operation of the chip removal mechanism 7, the waste chips intercepted by the filter screen 73 will fall downward under the action of gravity. Since the through port 711 is opened on the partition inside the box body 71, these fallen waste chips will fall into the collection box 712 located at the bottom of the box body 71 through the through port 711. When the waste chips in the collection box 712 accumulate to a certain amount and need to be cleaned, the operator can pull the handle 713 on the collection box 712 to pull out the collection box 712 from the bottom of the box body 71, and then dump and clean the waste chips in the collection box 712. After the cleaning is completed, push the collection box 712 back to the original position at the bottom of the box body 71 along the pull-out track to make it communicate with the through port 711 again for continuing to collect waste chips.

[0040] Specifically, such as Figure 1 、 Figure 6 and Figure 7As shown, the detection mechanism 9 further includes a cleaning component 94. The cleaning component 94 includes bristles 942 that contact the lens of the photodetector 91 through a mounting base 941. A feed hole 9411 communicating with its internal cavity is formed in the mounting base 941, and the mounting base 941 is communicated with the housing 75 through a connecting pipe 9412.

[0041] Among them, the bristles 942 are installed on the mounting base 941 and contact the surface of the lens of the photodetector 91. When the first lead screw slider 3 drives the motor group 5 on the mounting frame 4 to move, the bristles 942 will wipe the surface of the lens. Since the bristles 942 are in close contact with the lens, it can effectively remove impurities such as dust and debris attached to the surface of the lens, avoiding the influence of these impurities on the reception and detection accuracy of the reflected laser signal by the photodetector 91. In addition, when the induced draft fan 72 of the chip removal mechanism 7 works, a negative pressure suction is generated at the housing 75, and this suction will be conducted to the internal cavity of the mounting base 941 through the connecting pipe 9412, making a certain negative pressure environment also formed inside the mounting base 941. At this time, the impurities swept down by the bristles 942 will, under the action of the negative pressure, enter the internal cavity of the mounting base 941 through the feed hole 9411, and then be sucked into the housing 75 along the connecting pipe 9412, and finally enter the box body 71 of the chip removal mechanism 7 for collection and treatment. The cooperation between the cleaning component 94 and the chip removal mechanism 7 realizes the self-cleaning function of the detection mechanism 9, eliminating the need for manual frequent cleaning of the lens of the photodetector 91, reducing the workload and difficulty of manual maintenance, and improving the automation degree and working efficiency of the device.

[0042] Specifically, as Figure 9 shown, the mounting base 941 is detachably connected to the mounting frame 4 through a positioning sleeve 943. A positioning rod 944 cooperating with the positioning sleeve 943 is provided on the mounting base 941. A limit end 9442 is arranged on the positioning rod 944 through a mounting groove 9441, and a spring 9443 is arranged between the limit end 9442 and the inner wall of the mounting groove 9441. A limit hole 9431 cooperating with the limit end 9442 is formed in the positioning sleeve 943.

[0043] Among them, when the mounting base 941 needs to be installed on the mounting bracket 4, first align the positioning rod 944 with the positioning sleeve 943. During the process of inserting the positioning rod 944 into the positioning sleeve 943, the limiting end 9442 will be squeezed by the inner wall of the positioning sleeve 943, and thus shrink into the installation groove 9441, and the spring 9443 is compressed. When the positioning rod 944 continues to be inserted and the limiting end 9442 reaches the position of the limiting hole 9431 on the positioning sleeve 943, the elastic force of the spring 9443 will push the limiting end 9442 to pop out and snap into the limiting hole 9431, thereby realizing the fixed connection between the mounting base 941 and the mounting bracket 4. When the mounting base 941 needs to be disassembled, just apply a pressure to the limiting end 9442 towards the installation groove 9441, so that the limiting end 9442 overcomes the elastic force of the spring 9443 and retracts into the installation groove 9441. At this time, the positioning rod 944 can be pulled out of the positioning sleeve 943, thereby realizing the separation between the mounting base 941 and the mounting bracket 4. This detachable connection structure makes the installation and disassembly process of the mounting base 941 very simple and fast. The operator does not need to use complex tools and can complete the installation and disassembly of the mounting base 941 through simple operations, greatly improving the efficiency of equipment maintenance and repair.

[0044] As mentioned above, the above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
