However, the present application can be realized in many different forms, and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0024] Embodiment one, please refer to Figures 1-7 The present application provides a technical solution: A high-efficiency wood toy part drilling device, the device base frame includes a base 1. A discharge chute 11 is provided through the center of the top of the base 1, a foot pad 12 is vertically fixed and installed at each of the four corners of the lower bottom of the base 1, a top seat 13 is fixed and installed on the top of the base 1 through four support columns 14, and an opening is provided through the center of the top seat 13 to provide operating space for the processing area; A moving assembly is installed above the top seat 13 for precise movement of the drilling assembly, the moving assembly includes a transverse moving unit and a longitudinal moving unit, the transverse moving unit includes two first fixed seats 21, the two first fixed seats 21 are fixedly installed on the top of the top seat 13, a first lead screw 22 is rotatably installed between the two first fixed seats 21, a first nut seat 23 is threadedly installed on the first lead screw 22, a first servo motor 24 is vertically fixedly installed on the outer side wall of one of the first fixed seats 21, and the output end of the first servo motor 24 is fixedly connected with the first lead screw 22 for providing transverse moving power; The moving assembly further comprises two second fixing bases 25 fixedly installed on the top of the top base 13, a guide rod 26 fixedly connected between the two second fixing bases 25, a guide sleeve 27 slidably sleeved on the guide rod 26, a transverse moving plate 28 fixedly installed between the guide sleeve 27 and the first nut base 23, and a transverse moving hole formed through the transverse moving plate 28. This structure ensures that the transverse moving plate 28 moves stably without shaking in the transverse direction; The longitudinal moving unit comprises two third fixing bases 29 fixedly installed on the top of the transverse moving plate 28, a second lead screw 210 rotatably installed between the two third fixing bases 29, a second nut base 211 threadedly sleeved on the second lead screw 210, a slide rod 212 fixedly installed at the bottom of the second nut base 211 and penetrating through the transverse moving hole in the transverse moving plate 28, and a second servo motor fixedly installed on the outer side wall of one of the third fixing bases 29, with its output end connected with the second lead screw 210, for driving the slide rod 212 to longitudinally move; The drilling assembly is installed at the movable end of the moving assembly and is used for performing drilling work. The drilling assembly comprises a lifting electric cylinder 213 fixedly installed at the bottom of the slide rod 212, a drilling motor 214 installed at the output end of the lifting electric cylinder 213, and a drill bit 215 detachably installed at the output end of the drilling motor 214 through a drill chuck. The lifting electric cylinder 213 is responsible for providing stable drilling feed to ensure consistent hole depth. The core of the device is the workpiece conveying and fixing system. A third servo motor 3 is fixedly installed at the top of the base 1. The output end of the third servo motor 3 is fixedly connected with a rotating pipe 31. The center of the rotating pipe 31 is fixedly sleeved with a connecting base 32. Two air passages 33 symmetrically distributed above and below the center are formed through the pipe cavity of the rotating pipe 31 at both ends of the connecting base 32. A tray 4 is detachably inserted at both ends of the connecting base 32. The specific connection mode is that one plug 41 is fixedly installed at the lower cavity opening of each tray 4. The plug can be inserted into the corresponding air passage 33. A screw is threadedly inserted into the corresponding air passage 33 and pressed against the side surface of the corresponding plug 41, so as to realize quick installation and firm locking of the tray. This design facilitates quick replacement of special trays according to different shapes of workpieces. In order to realize airtight connection between the plug 41 and the air passage 33, an annular groove can be formed on the outer peripheral wall of the plug 41 and an O-shaped sealing ring can be nested. When the plug 41 is inserted into the air passage 33 and locked by the screw, the O-shaped sealing ring is compressed, so as to form reliable sealing between the plug and the inner wall of the air passage, preventing air leakage. A set of limiting baffle strips 42 are fixedly installed on the upper cavity of each tray 4, the inner contour of the limiting baffle strips is accurately designed according to the shape of the toy parts to be processed, and the core function thereof is to realize rapid nest positioning of the workpiece. The operator does not need to repeatedly adjust the alignment, but only needs to put the workpiece into the tray to automatically find the position. The lower surface of the limiting baffle strip 42 is processed into an inclined concave surface, and the angle range of the inclined concave surface is preferably 120° to 150°, so as to facilitate the smooth sliding of the debris; In order to further ensure the effectiveness of negative pressure adsorption, especially when processing wooden workpieces with slightly uneven or porous surfaces, a circle of flexible sealing material such as rubber or silicone sealing strip can be pasted on the top surface of the limiting baffle strip 42. When the workpiece is adsorbed, the sealing strip can be deformed to fill the micro gap between the workpiece and the baffle strip, thereby effectively improving the sealing performance and ensuring sufficient adsorption fixing force. The special structure has the dual functions of guiding the debris to smoothly fall into the inner cavity of the tray and preventing the debris from accumulating on the edge. A layer of high-mesh filter screen 43 is installed at the lower cavity opening of the tray 4 and communicated with the corresponding air duct 33. The mesh number of the filter screen 43 is preferably 80 to 120, which can effectively block the wood chips generated by drilling from being sucked into the rear air path, prevent the air duct 33 from being blocked, and protect the fan; The device integrates an intelligent air intake and exhaust system. A fan 5 is fixedly installed on the top of the base 1, and a fixed pipe 34 is fixedly connected with the outer shell of the fan 5 and is slidingly inserted into the inner cavity of the rotating pipe 31, so that the fixed pipe 34 remains stationary when the rotating pipe 31 rotates. The inner part of the fixed pipe 34 is arranged with an air suction pipe 51 and an air exhaust pipe 52, and the other ends of the air suction pipe and the air exhaust pipe are communicated with the fan 5. Two air holes 35 are formed in the outer wall of the fixed pipe 34 and penetrate the inner cavity; It should be noted that the core design of the air path system is that the fixed pipe 34 and the two air holes 35 thereon are fixed in space and do not change, no matter how the rotating pipe 31 rotates. The internal cavity structure ensures that one fixed air hole 35 is always aligned with the air duct 33 above the device, and the other fixed air hole 35 is always aligned with the air duct 33 below the device. Therefore, when the fan 5 is started, the inner cavity of the tray 4 located above the work station is continuously pumped through the air suction pipe 51 and the fixed air hole connected therewith, forming a negative pressure; at the same time, the inner cavity of the tray 4 located below the work station is continuously blown through the air exhaust pipe 52 and the other fixed air hole connected therewith, forming a positive pressure. This design realizes the automatic and accurate correspondence of the air path function after the rotating work station is switched, without the need for additional control valves; When the rotating pipe 31 rotates to the working position, the air suction pipe 51 is always communicated with the air duct 33 at the upper drilling work station through one air hole 35; the air exhaust pipe 52 is always communicated with the air duct 33 at the lower feeding and discharging work station through the other air hole 35. The system function is to form an automatic switching air path: continuously pumping the upper processing tray to form a vacuum, and using the negative pressure to firmly adsorb the workpiece on the limiting baffle strip; at the same time, the lower tray is blown into positive pressure air for cleaning the mold cavity and assisting in demolding.

[0025] Embodiment two: a high-efficiency drilling method for wooden toy parts This embodiment describes the specific process of the high-efficiency drilling method using the device described in embodiment one.

[0026] S1, initial cleaning and first station feeding. Start the fan 5, and the gas enters the inner cavity of the first tray in the lower station through the exhaust pipe 52, the corresponding air hole 35, and the lower air duct 33. The positive pressure airflow can remove the residual debris in the cavity, preparing for the placement of a new workpiece. The operator places the first wooden toy part in the clean first tray 4, with the workpiece periphery in contact with the limiting baffle 42, achieving rapid preliminary limiting.

[0027] S2, station switching and workpiece adsorption and fixation. Start the third servo motor 3, which drives the rotating pipe 31 and the connecting seat 32 to rotate one hundred and eighty degrees. This action rotates the first workpiece-carrying first tray to the upper displacement, becoming the drilling station; at the same time, it rotates the empty second tray to the lower displacement, becoming the feeding and discharging station. Then, the fan 5 continues to run, and the gas is extracted from the inner cavity of the first tray through the air suction pipe 51, the corresponding air hole 35, and the upper air duct 33 at this time. A negative pressure is formed in the cavity, and under the action of atmospheric pressure, the first workpiece is tightly and uniformly adsorbed on the limiting baffle 42, completing firm fixation before processing.

[0028] S3, parallel machining operation. The operator places the second wooden toy part in the second tray 4 in the lower station. At the same time, the control system operates the moving assembly and the drilling assembly to drill the first workpiece fixed in the upper station. The first servo motor 24 and the second servo motor operate according to the program, driving the drill bit 215 to move to the predetermined coordinate position; then the lifting cylinder 213 drives the drilling motor 214 and the drill bit 215 to descend, the drilling motor starts, and the drilling operation is completed. All wooden debris generated in this process is confined and falls into the inner cavity of the first tray, achieving in-situ collection of debris.

[0029] S4, secondary switching and automatic discharging and cleaning. After the first workpiece drilling is completed, start the third servo motor 3 to drive the rotating pipe 31 and the connecting seat 32 to rotate one hundred and eighty degrees again. This action rotates the first tray carrying the workpiece and debris to the lower station after processing is completed, while the second tray with the second workpiece is rotated to the upper station. The fan 5 continues to run, and the gas enters the inner cavity of the first tray through the exhaust pipe 52, the corresponding air hole 35, and the lower air duct 33 at this time. The positive pressure airflow and gravity work together to blow off the processed first workpiece and all the debris accumulated in the cavity, making them automatically discharged through the discharge chute 11 on the base, completing the efficient discharging and self-cleaning.

[0030] S5, cycle. While the lower station is automatically unloading, the upper station repeats the workpiece fixing process in step S2 and drills the second workpiece. This process makes the unloading, fixing, drilling and cleaning processes completely parallel in time and space, forming a high-efficiency continuous production cycle, which is repeated until all processing tasks are completed.

[0031] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application.
