Description

Technical Field

[0001] The present invention relates to the field of drilling robots, and specifically to an automatic drilling robot for wood board processing and its working method. Background Art

[0002] In the prior art, the drilling of wood boards is mostly realized by automated drilling robots. Generally, the mechanism of the drilling robot for drilling only has the drilling function and does not have a collaborative chamfering function. When grinding the burrs on the edge of the hole of the board, it is necessary to control another mechanism to process the burrs. Although this processing method can solve the burr problem, the sawdust generated when the burrs are cut will fly everywhere, affecting the breathing environment, and additional mechanisms and additional time are required. Therefore, it is necessary to collect or process the processed burrs separately when dealing with burrs, which greatly affects the processing efficiency. Moreover, under the requirement of multiple functions, the body of the drilling robot is too large and easily occupies a certain amount of working environment space. Summary of the Invention

[0003] The present invention provides an automatic drilling robot for wood board processing and its working method, which overcomes the deficiencies described in the background art.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows: An automatic drilling robot for wood board processing includes a robot body and a drilling device installed at the end of the robot body. The drilling device includes a housing, a functional member, and an electric push rod. The functional member is installed on the lower side of the housing. The electric push rods are symmetrically arranged on both sides of the housing, and the output shafts of the two electric push rods are connected to the functional member through a connecting plate to drive the functional member to move by the electric push rods. A drill rod passing through the functional member is provided at the lower end of the housing, and the drill rod is installed on the output shaft of a motor; There is a gap between the functional member and the drill rod, and a cleaning mechanism is provided inside the functional member. When drilling operations are carried out, the cleaning mechanism cleans the sawdust around the lower part of the functional member. When the functional member moves downward, the cleaning mechanism cleans the sawdust in the gap and on the surface of the drill rod; An extrusion convex ring protruding outward is provided at the lower end of the functional member. The extrusion convex ring has an arc-shaped surface. After the drill rod drills on the surface of the wood board, the extrusion convex ring is moved downward by the electric push rod to extrude the burrs around the hole until they break, and at the same time, the cleaning mechanism cleans the sawdust.

[0005] A preferred technical solution is that the cleaning mechanism includes a flowing water chamber, a fixed hollow tube, a connecting plate body, and a water supply pipe. The flowing water chamber is arranged inside the functional part. The connecting plate body is arranged on the surface of the functional part and is connected to the flowing water chamber. The connecting plate body is externally connected to a water pump through the water supply pipe for water supply. The flowing water chamber is connected to the gap. The fixed hollow tube is fixed at the lower end of the housing, inserted into the gap between the functional part and the drill rod, and extends to a position near the flowing water chamber inside the functional part; When the electric push rod does not control the downward movement of the functional part, the fixed hollow tube abuts against the surface of the flowing water chamber, and a flow channel is formed between the fixed hollow tube and the flowing water chamber. This flow channel extends to the outer surface of the functional part. When water is injected into the flowing water chamber through the water supply pipe, the water flows from this flow channel to the outer surface of the functional part.

[0006] A preferred technical solution is that the flowing water chamber includes a plurality of annular channels and a conical discharge chamber. The annular channels are arranged in sequence from top to bottom. Each annular channel includes an outer annular chamber and an inner annular chamber. Each inner annular chamber is respectively connected to the outer annular chamber and the connecting plate body through a connecting channel. Each inner annular chamber is provided with a plurality of drainage channels extending towards the middle of the functional part. The drainage channels adjacent up and down are connected through a vertical flow channel. The conical discharge chamber is connected to the lower end of the vertical flow channel; The vertical flow channel and the conical discharge chamber form the flow channel.

[0007] A preferred technical solution is that the conical discharge chamber is a conical structure with a smaller upper part and a larger lower part. The conical discharge chamber includes chamber one and chamber two. Chamber one is arranged in an array and connected to the upper end of chamber two. Chamber one corresponds to each vertical flow channel respectively, and the width of chamber one is greater than the width of the vertical flow channel.

[0008] A preferred technical solution is that the functional part is a conical structure with a larger upper part and a smaller lower part. The functional part and the conical discharge chamber are arranged oppositely in terms of orientation. After squeezing the burrs around the holes on the surface of the wooden board to break through the extrusion convex ring, the functional part is pressed down again to form a flared structure at the upper end of the hole.

[0009] A working method of an automatic drilling robot for wood board processing. During work, the drilling device needs to be moved to the surface of the wood board to be drilled. The drilling device is moved downward by the robot body, and the drill rod is driven to rotate by the motor inside the housing to form holes on the surface of the wood board. The functional part is moved downward by the electric push rod to squeeze the debris burrs at the end of the holes; Among them, when moving the functional part downward, it needs to be moved downward reciprocally twice, and the burrs at the end of the holes are squeezed successively during the two downward movements, and a flared structure at the upper end of the hole is formed.

[0010] Compared with the prior art, this technical solution has the following advantages: In the present invention, a simple lifting action of an electric push rod can be used to drive a functional part to move downward, so that while the functional part presses and breaks through the extrusion convex ring to remove hair debris and wood thorns, the hair debris and wood thorns are removed together by water flow. When the functional part rises and drills, the water flow covers the surrounding of the drilling working surface to avoid sawdust splashing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] As Figures 1 to 9As shown, an automatic drilling robot for wood board processing is proposed in the present invention, which includes a robot body 1 and a drilling device 2 installed at the end of the robot body 1. The drilling device 2 includes a housing 21, a functional part 22 and an electric push rod 23. The functional part 22 is installed on the lower side of the housing 21. The electric push rods 23 are symmetrically arranged on both sides of the housing 21, and the output shafts of the two electric push rods 23 are connected to the functional part 22 through a connecting plate 231 to drive the functional part 22 to move by the electric push rods 23. A drill rod 211 passing through the functional part 22 is provided at the lower end of the housing 21, and the drill rod 211 is installed on the output shaft of a motor; There is a gap between the functional part 22 and the drill rod 211, and a cleaning mechanism is provided in the functional part 22. When drilling operations are carried out, the cleaning mechanism cleans the wood chips around the lower part of the functional part 22. When the functional part 22 is moved downward, the cleaning mechanism cleans the wood chips in the gap and on the surface of the drill rod 211. An extrusion convex ring 221 protruding outward is provided at the lower end of the functional part 22, and the extrusion convex ring 221 has an arc-shaped surface. After the drill rod 211 drills on the wood board surface, the extrusion convex ring 221 is moved downward by the electric push rod 23 to squeeze the burrs around the hole to break, and at the same time, the cleaning mechanism cleans the wood chips; In traditional drilling operations, after drilling is completed, it is necessary to switch to a dedicated burr cleaning mechanism or equipment, which involves operations such as equipment adjustment, positioning, and workpiece transfer, consuming a lot of time. However, the drilling robot of the present invention integrates the drilling and cleaning functions. The functional part is driven to move by the electric push rod, and the cleaning mechanism synchronously cleans the wood chips during the drilling process and when the functional part is moved downward after drilling, without the need to switch equipment or processes additionally, greatly saving the time required for process switching and significantly improving the overall processing efficiency; Secondly, during the drilling process, the splashing of wood chips will not only pollute the working environment, but also may pose a hazard to the respiratory health of the operators, and even cause safety accidents such as fires. The cleaning mechanism of this drilling robot is provided with an extrusion convex ring protruding outward at the lower end of the functional part. When the drill rod drills on the wood board surface, the extrusion convex ring can squeeze the burrs around the hole to break, and at the same time, the cleaning mechanism cleans the wood chips around the lower part of the functional part, so that the wood chips can be cleaned in time after being generated, reducing the splashing and diffusion of wood chips in the air. Moreover, the existence of burrs will affect the appearance quality of the wood board and the subsequent assembly and use performance. The present invention drives the extrusion convex ring to move downward by the electric push rod to squeeze the burrs around the hole to break. This physical extrusion method can effectively remove the burrs, make the hole edge smoother and neater, improve the processing quality of the hole, and reduce problems such as scratches and interference caused by burrs.

[0023] Further, the cleaning mechanism includes a water flow chamber 222, a fixed hollow tube 223, a connecting plate body 224, and a water supply pipe 225. The water flow chamber 222 is arranged inside the functional member 22. The connecting plate body 224 is arranged on the surface of the functional member 22 and is connected to the water flow chamber 222. The connecting plate body 224 is externally connected to a water pump through the water supply pipe 225 for water supply. The water flow chamber 222 is connected to the gap. The fixed hollow tube 223 is fixed to the lower end of the housing 21. The fixed hollow tube 223 is inserted into the gap between the functional member 22 and the drill rod 211 and extends to a position close to the water flow chamber 222 inside the functional member 22; When the electric push rod 23 does not control the downward movement of the functional member 22, the fixed hollow tube 223 abuts against the surface of the water flow chamber 222, and a flow channel is formed between the fixed hollow tube 223 and the water flow chamber 222. The flow channel extends to the outer surface of the functional member 22. When water is injected into the water flow chamber 222 through the water supply pipe 225, the water flows to the outer surface of the functional member 22 through this flow channel.

[0024] When cleaning is required, an external water pump supplies water to the connecting plate body 224 through the water supply pipe 225. The connecting plate body 224 is connected to the surface of the functional member 22 and is connected to the internal water flow chamber 222. Water flows from the water supply pipe 225 into the connecting plate body 224 and then into the water flow chamber 222. In the normal state, that is, when the electric push rod 23 does not control the downward movement of the functional member 22, the fixed hollow tube 223 abuts against the surface of the water flow chamber 222. At this time, a flow channel is formed between the fixed hollow tube 223 and the water flow chamber 222. The flow channel extends to the outer surface of the functional member 22. When water is injected into the water flow chamber 222, the water flows along the formed flow channel to the outer surface of the functional member 22. The water flow forms a certain pressure and flow rate on the outer surface of the functional member 22, scouring the sawdust on the outer surface of the functional member 22, the surface of the drill rod 211, and the gap area. The scouring action of the water flow can effectively strip and carry away the sawdust from the surface of the drill rod and the gap area.

[0025] Moreover, the water flow chamber 222 includes a plurality of annular channels and a conical discharge chamber 300. The annular channels are arranged in sequence from top to bottom. Each annular channel includes an outer annular chamber 100 and an inner annular chamber 200. Each inner annular chamber 200 is respectively connected to the outer annular chamber 100 and the connecting plate body 224 through a connecting channel 101. Each inner annular chamber 200 is provided with a plurality of drainage channels 201 extending towards the middle of the functional member 22. The drainage channels 201 adjacent up and down are connected through a vertical flow channel 202. The conical discharge chamber 300 is connected to the lower end of the vertical flow channel 202; The vertical flow channel 202 and the conical discharge chamber 300 form the flow channel.

[0026] Moreover, the conical discharge cavity 300 has a conical structure with a smaller upper part and a larger lower part. The conical discharge cavity 300 includes a first chamber and a second chamber. An array of the first chambers is connected to the upper end of the second chamber. Each first chamber corresponds to a respective vertical flow channel 202, and the width of the first chamber is greater than the width of the vertical flow channel 202. Among them, the functional member 22 has a conical structure with a larger upper part and a smaller lower part. The functional member 22 is disposed opposite to the orientation of the conical discharge cavity 300. After the burrs around the holes on the wooden board surface are squeezed to break by the extrusion collar 221, the functional member 22 is pressed down again to form a flared structure at the upper end of the holes.

[0027] Moreover, in the automatic drilling robot for wooden board processing of the present invention, the up-and-down lifting movement of the functional member 22 is controlled by the electric push rod 23, and the shielding effect of the fixed hollow tube 223 on the flowing water cavity 222 can be achieved as follows: Effect when the functional member 22 rises, water flow channel closed: When the electric push rod 23 controls the functional member 22 to move upward, the distance between the functional member 22 and the fixed hollow tube 223 gradually increases. At this time, the flow channel between the fixed hollow tube 223 and the surface of the flowing water cavity 222 is gradually cut off. Since the lower end of the fixed hollow tube 223 is inserted into the gap between the functional member 22 and the drill rod 211 and extends to a position near the flowing water cavity 222 within the functional member 22, when the functional member 22 rises to a certain extent, the fixed hollow tube 223 will completely shield the opening part of the flowing water cavity 222, so that water flow cannot flow from the flowing water cavity 222 through the flow channel to the outer surface of the functional member 22; Water flow stops discharging outward: At this time, the water flow in the flowing water cavity 222 is blocked by the fixed hollow tube 223 and cannot continue to discharge outward along the flow channel. This restricts the water flow in the flowing water cavity 222 within the cavity and cannot wash the sawdust on the outer surface of the functional member 22, the surface of the drill rod 211, and the gap area. When the functional member 22 rises, the drill rod 211 can perform normal drilling operations without being interfered by the water flow; Effect when the functional member 22 descends, water flow channel opens: When the electric push rod 23 controls the functional member 22 to move downward, the distance between the functional member 22 and the fixed hollow tube 223 gradually decreases. At this time, the flow channel between the fixed hollow tube 223 and the surface of the flowing water cavity 222 is gradually formed and opened. When the functional member 22 descends to a certain position, a stable flow channel is formed between the fixed hollow tube 223 and the surface of the flowing water cavity 222. Water can flow from the flowing water cavity 222 through this flow channel to the outer surface of the functional member 22. At this time, the water supply pipe 225 injects water into the flowing water cavity 222, and the water flows along the formed flow channel to the outer surface of the functional member 22. The water forms a certain pressure and flow rate on the outer surface of the functional member 22, scouring the sawdust on the outer surface of the functional member 22, the surface of the drill rod 211, and the gap area. The scouring effect of the water can effectively strip and carry away the sawdust from the surface of the drill rod and the gap area. The sawdust washed down by the water is discharged from the outer surface of the functional member 22 together with the water.

[0028] It can be seen from this that in the present invention, a simple lifting action of the electric push rod 23 can be used to drive the functional member 22 to move downward, so that while the functional member 22 cuts off and removes the burrs and wood thorns by pressing the extrusion ring 221, the burrs and wood thorns are removed together by water flow. When the functional member 22 rises and the drilling work is carried out, the water flow covers the periphery of the drilling working surface to avoid sawdust splashing.

[0029] Based on the above content, a working method of an automatic drilling robot for wood board processing is also proposed in the present invention. During operation, the drilling device 2 needs to be moved to the surface of the wood board to be drilled. The drilling device 2 is lowered by the robot body 1, and the motor in the housing 21 is used to drive the drill rod 211 to rotate to form a hole on the surface of the wood board. The functional member 22 is lowered by the electric push rod 23 to squeeze the debris burrs at the end of the hole by the functional member 22. Among them, when the functional member 22 is lowered, it needs to be lowered reciprocally twice, and the burrs at the end of the hole are sequentially squeezed during the two descents to form a flared structure at the upper end of the hole.

[0030] Moreover, the drill pipe 211 rotates under the drive of the motor to drill the wooden board. At this time, the functional part 22 is in the initial position, and the extrusion convex ring 221 is located above the drill pipe 211 and does not contact the surface of the wooden board. During the drilling process, the wood chips are mainly cleaned by the cleaning mechanism including the brush, air flow, and water flow to ensure the cleanliness of the surface of the drill pipe and the clearance area. After the drilling is completed, the electric push rod 23 drives the functional part 22 to move downward. The extrusion convex ring 221 of the functional part 22 gradually contacts the area around the hole on the surface of the wooden board. The arc-shaped surface design of the extrusion convex ring 221 enables it to evenly apply pressure to the burrs around the hole. As the functional part 22 moves downward, the burrs are gradually squeezed and broken under the action of the pressure, thus eliminating the influence of the burrs on the subsequent processing. After the burrs are squeezed and broken, the electric push rod 23 continues to drive the functional part 22 to move downward. At this time, the lower end of the functional part 22 gradually enters the hole. Since the functional part 22 is a conical structure with a larger upper part and a smaller lower part, the diameter of its lower end gradually increases. When the functional part 22 moves further downward, the conical surface at its lower end will exert an outward extrusion force on the upper end of the hole. This outward extrusion force causes the upper end of the hole to gradually expand, forming a flared structure. The size and shape of the flare are determined by the conical structure of the functional part 22 to ensure that a uniform and regular flare is formed at the upper end of the hole.

[0031] The above is only a preferred embodiment of the present invention, and thus the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification should still fall within the scope covered by the present invention.
