Further, the left and right ends of the top of the mounting seat 18 are provided with a horizontal slide groove 35, and the front and rear ends of the top of the mounting seat 18 are provided with a longitudinal slide groove 36.

[0034] In this embodiment, the bamboo board input roller group 1, the bamboo board lifting roller group 2 and the bamboo board output roller group 3 all include a plurality of conveying rollers evenly spaced laterally. When the bamboo boards are conveyed normally, the heights of the bamboo board input roller group, the bamboo board lifting roller group and the bamboo board output roller group are the same.

[0035] In this embodiment, the bamboo board lifting roller group 2 is arranged inside the upper end of a U-shaped seat 19, and the upper end of the bamboo board lifting roller group 2 extends out of the U-shaped seat 19. The U-shaped seat 19 is driven to lift vertically by a first lifting cylinder 20 vertically arranged thereunder. A lifting support plate 21 is horizontally arranged inside the U-shaped seat 19 below the bamboo board lifting roller group 2. The lifting support plate 21 is driven to lift by a second lifting cylinder 22 vertically arranged thereunder. The second lifting cylinder 22 is installed on the inner bottom surface of the U-shaped seat 19. A plurality of vertical support plates 23 are fixed on the top of the lifting support plate 21, which are evenly spaced laterally and used to support the bottom of the bamboo board 7. Each vertical support plate 23 is located between two adjacent conveying rollers in the bamboo board lifting roller group 2. During operation, the first lifting cylinder 20 drives the U-shaped seat 19 to move upward, and the U-shaped seat 19 drives the bamboo board 7 to rise through the bamboo board lifting roller group 2. Then the first lifting cylinder 19 stops moving, and the second lifting cylinder 22 drives the vertical support plate 23 to move upward through the lifting support plate 21 and pass through the bamboo board lifting roller group 2 upward. The top of the vertical support plate 23 contacts the bottom of the bamboo board 7 on the bamboo board lifting roller group 2, and lifts the bamboo board on the bamboo board lifting roller group 2 upward, so as to facilitate the horizontal edges of the transverse splint 8 and the horizontal edges of the longitudinal splint 9 of the bamboo board positioning and clamping mechanism 6 to move to contact the bottom surface of the bamboo board 7 and support the bamboo board. After the drilling is completed, the second lifting cylinder 22 drives the vertical support plate 23 to reset downward, so that the bamboo board 7 on the vertical support plate 23 falls back onto the bamboo board lifting roller group 2, and then the first lifting cylinder 20 drives the bamboo board lifting roller group 2 and the bamboo board 7 to reset downward through the U-shaped seat 19 until the bamboo board lifting roller group 2 is flush with the bamboo board input 1 and output roller group 3 again.

[0036] In this embodiment, the drilling mechanism 5 includes a protective cover 24 with a closed top and an open bottom. The protective cover 24 is provided with a liftable drilling assembly 25 that can be lifted vertically and extended downward from the open bottom of the protective cover 24. The protective cover 24 is driven by a vertically arranged drilling lifting cylinder 26 to move downward and cover the drilling position of the bamboo board. The drilling lifting cylinder 26 is installed at the bottom of the moving end of the two-dimensional plane moving module 4. During operation, the two-dimensional plane moving module 4 drives the drilling lifting cylinder 26 and the protective cover 24 to move to the position directly above the position where the bamboo board 7 needs to be drilled. Then, the drilling lifting cylinder 26 drives the protective cover 24 to move downward until the bottom of the protective cover 24 contacts the surface of the bamboo board. Then, the liftable drilling assembly 25 extends downward from the open bottom of the protective cover 24 and drills the surface of the bamboo board 7. It should be noted that the two-dimensional plane moving module is an existing mature product, which includes a horizontal linear moving module and a longitudinal linear moving module. Its structure will not be repeated here.

[0037] In this embodiment, a vertical slot 27 is provided on the left side wall of the protective cover 24, and the vertical slot 27 penetrates the protective cover 24 in the radial direction; the liftable drilling assembly 25 includes a lifting plate 28 that penetrates the vertical slot 27 and slides with the vertical slot 27, and a drilling motor 29 is installed on the top of one end of the lifting plate 28 located inside the protective cover 24, and a drill bit 30 that penetrates the lifting plate 28 downward is fixed to the motor shaft of the drilling motor 29; a vertical cylinder 31 is fixed to the outer wall of the protective cover 24 just above the vertical slot 27, and the cylinder rod of the vertical cylinder 31 is fixedly connected to one end of the lifting plate 28 located outside the protective cover 24, so as to drive the lifting plate 28 to rise and fall along the vertical slot 27. During operation, the vertical cylinder drives the drill bit to rise and fall vertically through the lifting plate to realize the feeding of the drilling; and the lifting plate slides with the vertical slot, which can play a good guiding role in the lifting and falling of the drill bit.

[0038] In this embodiment, a dust suction hole 32 is provided at the lower end of the right side wall of the protective cover 24 and is through the protective cover in the radial direction. The dust suction hole 32 is connected to a dust suction device (not shown) through a dust suction pipe 33. Since the protective cover is used to cover the position where the drilling hole is required on the surface of the bamboo board, the debris generated by the drilling can be sucked away by the dust suction device through the dust suction hole and the dust suction pipe, effectively preventing the debris generated by the drilling from splashing and affecting the quality of the processing environment.

[0039] In this embodiment, the bottom open edge of the protective cover 24 is provided with an annular rubber ring 34 for contacting the top surface of the bamboo board 7. The annular rubber ring is used to contact the surface of the bamboo board to effectively prevent the protective cover from crushing the surface of the bamboo board.

[0041] Step S1, bamboo board input: the bamboo board input roller group 1 transports the horizontally arranged bamboo board 7 from left to right.

[0042] Step S2, bamboo board clamping: the vertical support plate 23 below the bamboo board lifting roller group 2 moves upward and lifts the bamboo board 7 on the bamboo board lifting roller group 2 upward, such as Figure 7 After that, the bamboo board positioning clamping mechanism 6 holds the bottom of the bamboo board 7 around and clamps the sides of the bamboo board 7 around, as shown Figure 8 As shown;

[0043] Step S3, drilling: the two-dimensional plane moving module 4 drives the drilling mechanism 5 to move to the position where the drilling hole is required on the surface of the bamboo board 7, and then the protective cover 24 of the drilling mechanism 5 moves downward and covers the position where the drilling hole is required on the bamboo board 7, and then the lifting drilling assembly 25 extends downward from the protective cover 24 and drills the surface of the bamboo board 7. Fig. 9 As shown; after one drilling is completed, the lifting drilling assembly 25 and the protective cover 24 are reset upward in turn, and the two-dimensional plane moving module 4 drives the drilling mechanism 5 to move to a drilling position under the surface of the bamboo board 7, and repeats the above drilling action;

[0044] Step S4, bamboo board output: after the bamboo board drilling is completed, the bamboo board positioning and clamping mechanism is reset to the outside, no longer clamping and supporting the bamboo board 7, and then the vertical support plate 23 is reset downward, so that the bamboo board 7 after drilling falls back on the bamboo board lifting roller group 2, and then the bamboo board lifting roller group 2 is reset downward, and the bamboo board lifting roller group 2 transports the bamboo board 7 after drilling from left to right to the bamboo board output roller group 3, and the bamboo board output roller group 3 outputs the bamboo board after drilling;

[0045] Step S5, repeating the above steps S1-S4 to drill holes in the next bamboo board.

[0046] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0047] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0048] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
