Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fiberboard processing, more particularly to a fiberboard silk-screen glue coating device with a mechanical arm. BACKGROUND

[0002] Fiberboard is a kind of man-made board, which is made of wood fiber or other plant fiber (such as bamboo, sugarcane residue) as the main raw material through processes such as crushing, drying, gluing and hot pressing. According to the density, it can be divided into low-density fiberboard (LDF), medium-density fiberboard (MDF) and high-density fiberboard (HDF). It has the characteristics of uniform texture, easy processing and low cost, and is widely used in furniture manufacturing, interior decoration, packaging and sound equipment fields. Its surface can be further decorated by pasting, spraying or silk-screening process.

[0003] In the existing fiberboard processing, especially in the silk-screening process, in order to ensure that the silk-screened pattern is more firmly attached to the surface of the fiberboard, pre-gluing is generally required on the surface to increase the adhesion. The traditional gluing method is generally manual use of stainless steel scraper or plastic scraper, relying on the operator's experience to control the glue layer thickness. With the development of technology and the needs of production, various automatic gluing devices have emerged, especially fiberboard silk-screening glue coating devices with mechanical arms, which greatly improve the efficiency of fiberboard silk-screening processing.

[0004] However, the existing fiberboard silk-screening glue coating device with a mechanical arm can improve the processing efficiency, but still has some deficiencies. 1. When the mechanical arm is used for a long time and fails or the fiberboard is damaged and cracked, the fiberboard fixed by the mechanical arm has the risk of falling. 2. The existing gluing device can only complete the gluing operation on the surface of the fiberboard and cannot detect the quality of the fiberboard itself, so the functionality is relatively single.

[0048] The working principle of the present application:

[0049] First, when silk-screening the fiber plate body 9, place the fiber plate body 9 to be processed on the top of the material placing table 102 of the fixed base 1, then start the hydraulic system 3, so that the hydraulic system 3 drives the hydraulic telescopic rod 4 to extend and retract, then the hydraulic telescopic rod 4 drives the fixed sleeve ring 5 and the clamping mechanical arm 6 to descend, then the clamping mechanical arm 6 descends so that the wireless induction transmitter 12 at the bottom of the movable sleeve approaches the fiber plate body 9 on the top of the material placing table 102, then the gradual descent of the clamping mechanical arm 6 causes the fiber plate body 9 to press the wireless induction transmitter 12 into the inside of the clamping mechanical arm 6, at this time the clamping mechanical arm 6 triggers the vacuum pump system 7 by the pressing signal, at this time the vacuum pump system 7 absorbs and discharges the air in the clamping mechanical arm 6, then the first gear 1001 and the second gear 14 engaged with it are rotated by the unpowered fan 10 in the clamping mechanical arm 6, then the third gear 1101 and the limiting sleeve ring 1102 are rotated by the second gear 14, then the protective assembly 8 is rotated by the rotation of the movable sleeve ring 11, then the blocking lead block 802 pushes the water in the water storage cavity 801 to press the anti-falling support plate 15, then the anti-falling support plate 15 rotates in the circular groove 101 and is limited by the material placing table 102 so that the blocking lead block 802 cannot move;

[0050] Then after the vacuum pump system 7 discharges the air in the clamping mechanical arm 6, the fiber plate body 9 is fixed by the negative pressure at the bottom of the clamping mechanical arm 6, then the hydraulic system 3 is started again, so that the hydraulic system 3 drives the hydraulic telescopic rod 4 and the fixed sleeve ring 5 to rise, then the clamping mechanical arm 6 lifts the fiber plate body 9, then the air in the clamping mechanical arm 6 is thin due to the blocking of the fiber plate body 9, then the unpowered fan 10 is in a static state, then the bottom of the fiber plate body 9 can be coated;

[0051] Then when the clamping mechanical arm 6 fails or the fiber plate body 9 is damaged, at this time the air in the clamping mechanical arm 6 is continuously sucked and discharged by the vacuum pump system 7, then the unpowered fan 10 is driven to rotate by the air flow, and the second gear 14 and the movable collar 11 are accelerated to rotate, then the rotation of the second gear 14 drives the protective assembly 8 to rotate quickly, then the blocking lead block 802 pushes the water in the water storage cavity 801 to extrude the anti-falling support plate 15, then the anti-falling support plate 15 pulls the auxiliary telescopic sleeve 16 to move to the bottom position of the fiber plate body 9, then the bottom position of the fiber plate body 9 is lifted by the telescopic plate 1501, at this time the fiber plate body 9 cannot directly fall, then the rectangular limiting block 1504 is pushed by the first spring 1506 to limit the position of the telescopic telescopic plate 1501, avoid the telescopic plate 1501 being pulled into the protective assembly 8 through the auxiliary telescopic sleeve 16, so as to ensure the safety of the clamping mechanical arm 6.

[0052] Then when the clamping mechanical arm 6 normally uses the fiber plate body 9 and appears a larger aperture or a small crack, at this time the air or the crack size of the fiber plate body 9 enters different flow rates of air in the clamping mechanical arm 6, then the different air flow rates in the clamping mechanical arm 6 change the rotation speed of the unpowered fan 10, then the movable collar 11 drives the protective assembly 8 to rotate, then the blocking lead block 802 generates different centrifugal forces due to the rotation speed, then the rotation speed of the protective assembly 8 and the extension length of the anti-falling support plate 15 can be observed through the transparent observation window 201 to determine whether the quality of the fiber plate body 9 is qualified.

[0053] Finally, it should be pointed out that: first, in the description of the present application, it should be pointed out that unless otherwise specified and limited, the terms "installation", "connection", "connection" should be understood broadly, which can be mechanical connection or electrical connection, or the communication between two elements, or direct connection, "up", "down", "left", "right" and the like are only used to indicate the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may change;
