Description

Technical Field

[0001] The invention relates to the field of furniture plate drilling, and in particular to an automatic leakage prevention detection system for furniture plate drilling. Background Art

[0002] Blind holes are often required when processing home furnishing panels. However, during the processing, blind holes are often drilled into through holes, causing the entire panel to be scrapped and unusable. Therefore, it is necessary to inspect the holes on the panel to check whether there are any blind holes that have been drilled into through holes. The traditional method of detecting through holes uses infrared rays for detection, and an infrared receiver is set on the other side. However, when drilling blind holes and through holes, a large amount of wood chips often remain inside the holes, resulting in the infrared rays being unable to pass through normally, and the through holes are often detected as blind holes. Although fans or blower structures are set up on the production line, wood chips are often stuck inside the holes in the form of long spirals, which are difficult to blow away with conventional air volume. In addition, using large-scale blowing cannot effectively remove the wood chips in the holes. Only some small wood chips can be removed, which reduces the accuracy of hole detection.

[0003] Therefore, those skilled in the art have designed an automatic detection system for preventing leakage from drilling holes in furniture panels to solve the above problems. Summary of the Invention

[0004] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide an automatic detection system for preventing leakage when drilling holes in furniture panels, which can be adapted to the welding of meshes with different spacings.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: it includes an outer frame, a plurality of blowing ends connected in series are installed on the inner side of the top of the outer frame, a detection end corresponding to the blowing end is installed on the inner side of the bottom of the outer frame, the blowing end includes a connecting pipe, a hemispherical shell, an exhaust hole, a counterweight rod and a connecting ring, both ends of the connecting pipe are connected to the outer frame, two hemispherical shells are provided, and are sleeved on the outer wall of the connecting pipe, the exhaust hole is opened on the outside of the connecting pipe, and the exhaust hole is located in the two hemispherical shells, the counterweight rod is rotatably connected to the outer wall of the connecting pipe, and the connecting ring is installed on the outside of the two hemispherical shells.

[0006] Preferably, an air pump is installed at the axial end of the connecting tube, the counterweight rod is located inside the sphere composed of two hemispherical shells, the counterweight rods are evenly distributed around the outside of the connecting tube, and there are at least four counterweight rods, with adjacent two counterweight rods facing different directions.

[0007] Preferably, the rotation point between the counterweight rod and the connecting tube deviates from the center of the sphere after the two hemispherical shells are spliced together, and the counterweight ball end and the rotation point end of a single counterweight rod cannot be located on the inner side of the same hemispherical shell.

[0008] Preferably, when the hemispherical shell and the connecting tube rotate, the counterweight ball end of the counterweight rod on the connecting tube will expand outwards to push the two hemispherical shells away from each other along the direction of the connecting tube.

[0009] Preferably, the connecting ring includes a ring body, a blocking ball, an air pressure tube and a spring. The ring body is sleeved on the joint of the two hemispherical shells. A gap is provided on the inside of the ring body to accommodate the blocking ball. One side of the air pressure tube is connected to the gap, and the other side is connected to the sphere after the two hemispherical shells are spliced together. A spring is provided on the inside of the ring body and is connected to the two hemispherical shells.

[0010] Preferably, an air vent passes through the inside of the blocking ball, and the pipe opening of the air vent pipe and the pipe opening of the wind pressure pipe are not arranged correspondingly. When the blowing end is attached to the upper surface of the plate, the blocking ball is tightly attached to the inner wall of the gap, and the blocking ball is tightly attached to the pipe opening where the wind pressure pipe is connected to the gap.

[0011] Preferably, the outer frame is wrapped around the outside of the drilling platform, and the blowing end is located above the transmission belt of the drilling platform, and the detection end is located below the transmission belt of the drilling platform.

[0012] The invention has the following beneficial effects: the blowing end is used to blow air, and the detection end detects whether there is air flow. Since the holes in the plate are blind holes, if the detection end detects air flow, it means that the holes in the plate are leaking, and unqualified products can be quickly screened out. Furthermore, the present invention adopts a spherical structure that rolls under the push of the plate, and utilizes the centrifugal force to spread the counterweight rod to both sides and push the two spheres to open outwards, allowing the internal air pressure to leak out naturally. In addition, the connecting ring of the present invention is also provided with an automatic hole detection function, and air will be blown out only when it contacts a hole, thereby ensuring the internal air pressure to a certain extent and avoiding insufficient wind force. At the same time, the present application adopts the method of blowing air outwards to blow away the wood chips inside the hole. Compared with the traditional infrared detection method, the blowing method can more easily avoid the interference of wood chips and improve the accuracy of detection.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood in specific circumstances.

[0026] Example 1: The present invention provides a furniture board drilling leak prevention automatic detection system, such as Figure 1-7 As shown, it includes an outer frame 1, a plurality of blast ends 2 connected in series are installed on the inner side of the top of the outer frame 1, a detection end 3 corresponding to the blast end 2 is installed on the inner side of the bottom of the outer frame 1, and the blast end 2 includes a connecting pipe 201, a hemispherical shell 202, an exhaust hole 203, a counterweight rod 204 and a connecting ring 205. Both ends of the connecting pipe 201 are connected to the outer frame 1, two hemispherical shells 202 are provided, and are sleeved on the outer wall of the connecting pipe 201, the exhaust hole 203 is opened on the outside of the connecting pipe 201, and the exhaust hole 203 is located in the two hemispherical shells 202, the counterweight rod 204 is rotatably connected to the outer wall of the connecting pipe 201, and the connecting ring 205 is installed on the two hemispherical shells 2 02 On the outside, the blowing end 2 mainly plays the role of blowing air to the surface of the board, while the detection end 3 is mainly used to measure the air flow rate. The two are respectively located on the upper and lower sides of the processed board. After drilling the board surface, it is necessary to detect whether the hole has been completely penetrated and whether there is leakage. The main method is to use the blowing end 2 to discharge air downward, and the detection end 3 to detect whether there is air flow. If there is air flow, it means that the hole has been completely penetrated. If there is no air flow, it means that the hole has not been penetrated and there is no leakage. In this way, all the wood chips in the hole can be blown away. Compared with traditional infrared sensing measurement, there is no problem of wood chips stuck in the hole and inaccurate detection.

[0027] An air pump is installed at the axial end of the connecting tube 201. The air pump mainly plays the role of pumping air outwards. The gas is loosened along the direction of the connecting tube 201 and enters the two hemispherical shells 202 through the exhaust hole 203, forming air pressure in the two hemispherical shells 202. The counterweight rods 204 are located on the inner side of the sphere composed of the two hemispherical shells 202. The counterweight rods 204 are evenly distributed around the outside of the connecting tube 201, and there are at least four counterweight rods 204. The directions of the adjacent two counterweight rods 204 are different, and the upper and lower counterweight rods 204 are arranged in a circle. The two counterweight rods 204 are in the same group, and the left and right counterweight rods 204 are in the same group. When the counterweight rods 204 rotate, they will drive all the counterweight rods 204 to rotate together and continue to spread outward under the action of centrifugal force. During the spreading process, the counterweight ends of the counterweight rods 204 will push the two sides of the hemispherical shell 202, so that the two hemispherical shells 202 are separated from each other. The upper and lower counterweight rods 204 push the hemispherical shell 202 on one side, and the left and right counterweight rods 204 push the other hemispherical shell 202.

[0028] The rotation point between the counterweight rod 204 and the connecting tube 201 deviates from the center of the ball after the two hemispherical shells 202 are spliced together. The counterweight ball end and the rotation point end of a single counterweight rod 204 cannot be on the inner side of the same hemispherical shell 202. The rotation point of the counterweight rod 204 is located at a position deviated from the center of the ball, and the direction of deviation is along the direction of the connecting tube 201. The upper and lower counterweight rods 204 are offset to the right, and the left and right counterweight rods 204 are offset to the left. The purpose of the offset is to draw a circle different from the hemispherical shell 202 when the two counterweight rods 204 rotate, so that the counterweight rod 204 can form contact with the inner wall of the hemispherical shell 202.

[0029] When the hemispherical shell 202 and the connecting tube 201 rotate, the counterweight ball end of the counterweight rod 204 on the connecting tube 201 will expand outward to push the two hemispherical shells 202 away from each other along the direction of the connecting tube 201. Since the rotation center of the counterweight rod 204 is offset from the center of the ball, it will contact the inner wall of the hemispherical shell 202 during rotation, thereby pushing the inner side of the hemispherical shell 202 to move to both sides through the counterweight end.

[0030] The connecting ring 205 includes a ring body 2051, a blocking ball 2052, an air pressure pipe 2053 and a spring 2054. The ring body 2051 is sleeved on the joint of the two hemispherical shells 202. A notch is provided on the inner side of the ring body 2051 to accommodate the blocking ball 2052. One side of the air pressure pipe 2053 is connected to the notch, and the other side is connected to the sphere after the two hemispherical shells 202 are spliced. When the blocking ball 2052 contacts the surface of the plate, the blocking ball 2052 will be pressed inward, completely blocking the air pressure pipe 2053. When it contacts the hole on the plate, it will naturally fall downward, completely opening the channel, forming a structure that will only eject air inward when it contacts the hole. A spring 2054 is provided on the inner side of the ring body 2051 and is connected to the two hemispherical shells 202. The spring 2054 can pull the two hemispherical shells 202 tight against each other, and they can only separate from each other by overcoming the force of the spring 2054 under the push of the counterweight rod 204.

[0031] An air vent runs through the inside of the blocking ball 2052, and the mouth of the air vent is not corresponding to the mouth of the wind pressure pipe 2053. The mouth of the air vent is not coaxial with the wind pressure pipe 2053, so that the blocking ball 2052 will only eject air outwards when it is not squeezed, forming a fixed-point jet to the hole on the plate. When the blowing end 2 is attached to the upper surface of the plate, the blocking ball 2052 is tightly attached to the inner wall of the gap, and the blocking ball 2052 is tightly attached to the mouth of the wind pressure pipe 2053 connected to the gap. When the blocking ball 2052 is subjected to the reverse force of the plate, the blocking ball 2052 will block the outlet of the wind pressure pipe 2053, forming a sealed wind-blocking structure to prevent the internal wind from overflowing outwards.

[0032] The outer frame 1 is wrapped around the outside of the drilling platform, and the blowing end 2 is located above the transmission belt of the drilling platform, and the detection end 3 is located below the transmission belt of the drilling platform. Since the holes to be drilled in this plate are blind holes, not through holes, once a through hole appears, it means that there is a processing error in the plate. When the wind blown out by the blowing end 2 is detected by the detection end 3, it means that a through hole has been formed here.

[0033] When in use, first keep the bottom of the blowing end 2 flush and in contact with the upper surface of the plate. Since the plate is pushed forward by the conveyor belt, the movement of the plate can drive the sphere of the blowing end 2 to rotate, thereby driving the internal connecting tube 201 and the counterweight rod 204 to rotate. Under the action of centrifugal force, the counterweight rod 204 expands outward, pushing the left and right hemispherical shells 202 to open outward, and when the blowing end 2 contacts the hole on the surface of the plate, it sprays air into the inside of the hole. Once the detection end 3 detects the flow of wind, it means that this hole is already a through hole and leakage occurs, so the processing is unqualified. When blowing air into the hole, the wood chips inside can also be blown away.

[0034] It should be noted that the above-described specific embodiments are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that various modifications, equivalent substitutions, and variations may be made to the present invention. However, as long as these modifications do not depart from the spirit of the present invention, they are intended to be within the scope of protection of the present invention. Furthermore, certain terms used in the specification and claims of this application are not intended to be limiting and are provided solely for ease of description.
