Description

Technical Field

[0001] The present application relates to the technical field of plate hemming, and in particular to a fully automatic hemming device for decorative plates and a method for hemming decorative plates. Background Art

[0002] Decorative panels are made from a variety of materials. Currently, one type of decorative panel on the market generally consists of a hardboard, soft filling, and a surface covering. The covering is then stapled to the hardboard using staples or a staple gun. The soft filling is sandwiched between the hardboard and the covering. The hardboard is typically wood, plastic, or other high-density materials. The soft filling is typically sponge or foam, and the surface covering is typically leather or fabric. To facilitate the automated hemming of these decorative panels, automated hemming and hemming equipment is now becoming available.

[0003] Generally speaking, in order to ensure that the decorative board has a better edging effect, the hardboard and the surface wrapping layer are generally rectangular, and the area of ​​the surface wrapping layer is much larger than that of the hardboard, so the four corners of the surface wrapping layer need to be cut, and glue needs to be sprayed on the back side of the hardboard to bond the side of the surface wrapping layer, and it may also be necessary to cut off the excess side of the surface wrapping layer.

[0004] For example, the Chinese patent application number 202111397236.X discloses an auxiliary edge trimming device for decorative panels, including a frame, a barrier part, a clamping mechanism and a pressing mechanism. The barrier part and the clamping mechanism are both arranged on the frame. The clamping mechanism cooperates with the barrier part to clamp the side edge of the decorative panel to be wrapped. The pressing mechanism is arranged on the outside of the decorative panel to be processed. The pressing mechanism is used to automatically press the excess side part of the surface wrapping layer on the upper surface of the side edge of the hard board. The decorative panel to be processed is arranged horizontally relative to the frame.

[0005] Regarding the above-mentioned related technologies, the inventor believes that there are the following defects:

[0006] When using conventionally designed edge trimming equipment, it is necessary to manually clamp the side of the surface wrapping layer and then drag the outside of the hard board before subsequent edge wrapping operations can be performed. In addition, the edge trimming equipment cannot perform operations such as corner cutting, gluing, and cutting, and has the disadvantage of low production efficiency, and therefore needs to be improved.

The edge clamping and dragging mechanism 600 is used to clamp and fix the side of the surface wrapping layer 900 and drag the surface wrapping layer 900 to slide relative to the hard board 800. The back push bonding mechanism 700 is used to squeeze and bond the side of the surface wrapping layer 900 to the back side of the hard board 800 coated with glue.

[0064] The use process of the fully automatic hemming equipment for decorative panels in the embodiment of the present application is roughly as follows:

[0065] Place the hard board 800 on the workbench 100, and then lay the surface wrapping layer 900 on the hard board 800. Start the edge clamping and dragging mechanism 600 to clamp and fix the side of the surface wrapping layer 900 and drag the surface wrapping layer 900 to slide relative to the hard board 800. Start the local functional modules of the corner cutting and gluing cutting device 400 to punch the corners of the surface wrapping layer 900 and spray glue on the back side of the hard board 800. Start the edge pressing device 300 to By pressing the side of the surface wrapping layer 900 against the upper surface of the side of the hard board 800 and pressing the excess side of the surface wrapping layer 900 against the side end surface of the hard board 800, the back-push bonding mechanism 700 is started, and the side of the surface wrapping layer 900 can be squeezed and bonded to the back side of the hard board 800 coated with glue. The local functional module of the corner cutting, gluing and cutting device 400 is started again, and the side of the surface wrapping layer 900 that is still excess after being bonded to the back side of the hard board 800 can be cut.

[0068] Please refer to Figure 2 、 Figure 3 and Figure 9The edge pressing device 300 includes a fixed beam 31, a downward pressing unit 32, a side pushing unit 33 and a pressing drive unit. The downward pressing unit 32 and the side pushing unit 33 are both vertically slidably assembled on the same side of the fixed beam 31. The pressing drive unit is installed on the fixed beam 31 and is used to drive the downward pressing unit 32 and the side pushing unit 33 to move up and down. The downward pressing unit 32 is used to press the side edge of the surface wrapping layer 900 against the upper surface of the side edge of the hard board 800, and the side pushing unit 33 is used to press the excess side edge of the surface wrapping layer 900 against the side end surface of the hard board 800.

[0069] By starting the pressing drive unit, the downward pressing unit 32 can be driven to press the side of the surface wrapping layer 900 against the upper surface of the side of the hard board 800. At the same time, the side pushing unit 33 can be driven to press the excess side of the surface wrapping layer 900 against the side end surface of the hard board 800. Therefore, the surface wrapping layer 900 can fit tightly against the side end surface of the hard board 800, and the edge wrapping is more secure.

[0070] In this embodiment, the pressing unit 32 includes a vertical plate 321 and a lower pressing plate 322 . The vertical plate 321 is vertically connected to the upper surface of the lower pressing plate 322 and forms an inverted T-shaped structure (it may also be an L-shaped structure in other embodiments).

Specifically, the compression drive unit comprises a plurality of spaced apart compression and telescopic power members 34, which are fixed to the side of the fixed beam 31 and operate synchronously. The compression and telescopic power members 34 are pneumatic cylinders, but can also be hydraulic cylinders or electric push rods.

[0076] In other embodiments, the downward pressing unit 32 and the side pushing unit 33 can be designed as separate units, and the pressing drive unit is composed of multiple spaced apart pressing and retractable power members 34. Some of the pressing and retractable power members 34 work synchronously to drive the downward pressing unit 32, while other parts of the pressing and retractable power members 34 work synchronously to drive the downward pushing unit 33.

[0092] The clamping unit 61 includes a first clamping plate 611, a second clamping plate 612, a power unit, and a deformable buffer. The first clamping plate 611 slides freely along a first direction perpendicular to the length of the first clamping plate 611. The first clamping plate 611 and the second clamping plate 612 are arranged in parallel. The power unit is connected to the first clamping plate 611 and / or the second clamping plate 612 and is used to drive the second clamping plate 612 toward or away from the first clamping plate 611. The deformable buffer is provided on the first clamping plate 611 and / or the second clamping plate 612.

[0093] The drag driving unit 62 is connected to the first clamping plate 611 and is used to drive the clamping unit 61 to slide back and forth along the first direction.

[0094] In this embodiment, the power unit is connected between the first clamping plate 611 and the second clamping plate 612. In other embodiments, the power unit can also be installed on other components as long as the output end of the power unit is connected to the first clamping plate 611 or the second clamping plate 612.

[0095] By starting the power unit, the second clamping plate 612 can be driven close to the first clamping plate 611, so that the side of the surface wrapping layer 900 is clamped and fixed. Even if the width of the surface wrapping layer 900 is wider, there is no need to arrange staff to manually clamp it. The added deformable buffer part has the characteristic of being deformable, so the deformable buffer part can effectively prevent the leather or the surface wrapping layer 900 from being clamped, and the protection effect on the leather or the surface wrapping layer 900 is better. By starting the dragging drive unit 62, the dragging operation can be automatically performed. The degree of automation of the entire mechanism is high, which saves time and effort, and greatly improves the hemming efficiency.

[0096] In this embodiment, the drag sliding unit 63 is disposed between the drag driving unit 62 and the first clamping plate 611 , and a plurality of groups of the drag sliding units 63 are spaced apart along a second direction, which is perpendicular to the first direction.

[0097] The drag sliding unit 63 includes: a drag guide rail 631, a drag slider 632 and a drag sliding plate 633. The length direction of the drag guide rail 631 is the first direction. The drag slider 632 is fixed to the lower surface of the drag sliding plate 633. The drag slider 632 is slidably assembled on the drag guide rail 631.

[0113] The right-angle surface formed by the side baffle 711 and the supporting plate 712 can better fit the side of the decorative board. When the bonding drive unit 72 is started, the side pushing unit 71 can be driven to gradually approach the side of the decorative board, and then the side baffle 711 presses the side of part of the surface wrapping layer 900 to the side end face of the hard board 800, and the supporting plate 712 squeezes and bonds the side of the surface wrapping layer 900 to the back side of the hard board 800 coated with glue.
