Description

Technical Field

[0001] The invention relates to the technical field of self-cleaning conveying, and in particular to an improved bellows dust-free drag chain housing and a self-cleaning conveying device thereof. Background Art

[0002] Drag chains, also known as cable protection drag chains, are devices that bind cables or wires or air and hydraulic pipes to facilitate their rotation and movement. Drag chains are used in reciprocating motion situations and can pull and protect built-in cables, oil pipes, air pipes, water pipes, etc. Drag chains have been widely used in CNC machine tools, electronic equipment, glass machinery, injection molding machine manipulators, handling machinery, plastic machinery, lifting equipment, woodworking machinery, automotive industry, industrial vehicles, metal processing machines, machine tools, casting machinery, port equipment, flat panel display equipment, semiconductor equipment and other industries.

[0003] Plastic drag chains are generally used on automation equipment. The advantage of using plastic drag chains is that they are light in weight and easy to move and operate automation equipment. The existing dust-free drag chain shell is usually formed by buckling two upper and lower shells. When in use, when the cable air pipe is placed in the drag chain and needs to be closed, the side strips of the two shells need to be quickly buckled. The side strip buckling is generally achieved by a snap-on structure. The corrugated top and corrugated side of each corrugated part in the existing dust-free drag chain shell are arc structures, that is, the crest position and both sides of the crest are arc structures. When the drag chain reciprocates, the contact position between the crest and the bearing surface is line contact, which is similar to blade contact and is prone to cutting and wear; in addition, the position where adjacent corrugated parts squeeze each other under the action of gravity is also line contact, which is similar to blade contact, and is also prone to cutting and wear, and is prone to slipping, and has poor force-bearing capacity stability; in addition, the existing bellows are not flexible enough and cannot meet the long-term bending, expansion, and rotation of the bellows drag chain.

[0004] The bellows drag chain shell runs at high speed, and the corrugated surface is more likely to accumulate dust, bacteria, oil, etc. For production lines with high cleanliness requirements, the dirt on the corrugated surface can easily have an adverse effect on product production. Summary of the invention

[0013] The working steps are: S1. When the bellows drag chain is in the maintenance state, the moving end of the bellows drag chain is disassembled from the head or action end of the equipment, and the end of the bellows drag chain shell is sealed; S2. The AGV automatically runs to the position of the bellows drag chain that needs to be cleaned according to the signal; S3. The first six-axis robot arm sucks or clamps the first clean conveyor box so that the first clean conveyor box is located at the bottom, and the second six-axis robot arm sucks or clamps the second clean conveyor box so that the second clean conveyor box is located at the top; S4. The end of the bellows drag chain is placed between the first clean conveyor box and the second clean conveyor box, and the conveying rollers in the first clean conveyor box and the second clean conveyor box are controlled to be in the extended position, and the conveying rollers are in contact with the surface of the bellows shell. The driving device drives the conveying rollers in the first clean conveyor box and the second clean conveyor box to rotate forward and reversely. When the roller rotates forward, the conveying roller drives the bellows shell to move to one side, and when the conveying roller rotates reversely, the conveying roller drives the bellows shell to move to the other side, and drives the bellows shell to reciprocate between the first clean conveying box and the second clean conveying box through the conveying roller, and at the same time controls the dust collection device, the decontamination and dehumidification unit, the sterilization lamp and the second detection part to start working; S5, the second detection part detects the surface condition of the bellows in real time.

According to the AGV's docking position and the positions of the first clean conveying box and the second clean conveying box, it can be selected whether to rotate the rotatable part. If the rotatable part needs to be rotated, the driving mechanism drives the rotatable part to rotate an appropriate angle to rotate the fixed end, so as to facilitate the placement of the bellows drag chain between the first clean conveying box and the second clean conveying box.

[0015] The first clean conveying box and the second clean conveying box are both provided with retractable smooth brackets on their sides to temporarily support the bellows drag chain housing when the bellows drag chain housing extends out of the first clean conveying box and the second clean conveying box.

Preferably, the platform surface at the top of the corrugation accounts for 40% of the top of the corrugation, which can not only solve the problem of cutting wear caused by line contact between the contact position of the wave crest and the bearing surface, but also reduce the problems of large friction, large wear and large dust caused by the large plane area. The corrugated side parts on both sides of the corrugated part form a side plane, and the mutually squeezed position B between adjacent corrugated parts is also in surface contact. When cables are installed in the improved bellows dust-free drag chain housing, due to suspension and gravity, the improved bellows dust-free drag chain housing bends so that adjacent corrugated parts are squeezed against each other.

The depth D between the crests and troughs of the corrugated pipe is 6-7mm, which is greater than the depth between the crests and troughs of the existing corrugated pipes. To a certain extent, the deeper the depth between the crests and troughs, the better the softness of the corrugated pipe. The depth between the crests and troughs of the corrugated pipe of the present invention is 6-7mm, and the softness of the corrugated pipe is better, which is more conducive to the bending, expansion and contraction, and rotation of the corrugated pipe and the internal cables. Preferably, the depth between the crests and troughs is 6.08mm. A first detection unit is provided on the upper side of the motion trajectory of the straight part. The first detection unit is used to monitor the dirtiness of the surface of the corrugated pipe shell in real time. When the dirtiness reaches a certain condition, the control device controls the self-cleaning conveying device to automatically clean the upper and lower surfaces of the corrugated pipe shell to avoid the dust, bacteria, oil stains, etc. accumulated on the surface of the corrugated pipe from causing adverse effects on the product. The self-cleaning conveying device for the bellows shell at least includes a control device, an AGV trolley, a robotic arm and a cleaning conveying box. The cleaning conveying box is provided with conveying rollers, a dust suction port, a decontamination and dehumidification unit, a sterilization lamp and a second detection part. When the bellows drag chain is in working state, non-working state and maintenance state, the surface of the bellows can be self-cleaned according to the situation to avoid the adverse effects of dirt on the surface of the corrugated structure on the production of products.

[0025] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Example 1

[0027] like Figure 1-4 As shown, an embodiment of the present invention provides an improved bellows dust-free drag chain housing 100, comprising an upper shell 101 and a lower shell 102, wherein the outer sides of the upper shell 101 and the lower shell 102 are respectively provided with snap-fitting edge strips 103 along the length direction, and the surfaces of the upper shell 101 and the lower shell 102 are respectively provided with corrugated portions 104, and a tubular cavity portion is formed in the upper shell 101 and the lower shell 102; the corrugated top of each corrugated portion 104 forms a platform surface 1041, so that the contact position A between the improved bellows dust-free drag chain housing 100 and the bearing surface is surface contact, and the plane contact surface is enlarged. Experiments have shown that the fatigue resistance of the contact with the external part is better, and the wear between the bearing surface is smaller.

[0028] The corrugated side portions on both sides of the corrugated portion 104 form a side plane 1042, and the mutually squeezed position B between adjacent corrugated portions 104 is also in surface contact. When cables are installed in the improved bellows dust-free drag chain housing, the improved bellows dust-free drag chain housing bends due to suspension and gravity, so that adjacent corrugated portions are squeezed against each other. The surface contact between adjacent corrugated portions is more conducive to reducing wear, improving force stability, and increasing anti-bending bearing capacity.

[0029] The platform surface 1041 at the top of the corrugation is transitionally connected to the side plane 1042 of the side of the corrugation through the arc surface 1043. The platform surface 1041 at the top of the corrugation accounts for 20%-60% of the top of the corrugation, which can not only solve the problem of cutting wear caused by line contact between the contact position of the wave crest and the bearing surface, but also reduce the problems of large friction, large wear and large dust caused by the large plane area. Preferably, the platform surface 1041 at the top of the corrugation accounts for 40% of the top of the corrugation. The size of the side plane 1042 should be able to achieve surface contact between adjacent corrugated parts at the mutually squeezed position.

[0030] Preferably, the platform surface 1041 at the top of the corrugation and the side plane 1042 at the side of the corrugation can be detachably mounted with a smooth part, which reduces the friction generated when the corrugated pipe runs at high speed. When the corrugated pipe is worn to a certain extent, a new smooth part can be replaced, thereby increasing the service life of the corrugated pipe and reducing the cost of replacing the corrugated pipe. The smooth part can be mounted by gluing to the platform surface and the side plane, or by other means, as long as the smooth part can be detachably replaced.

[0031] The depth D between the crests and troughs of the corrugated tube is 6-7 mm, which is greater than the depth between the crests and troughs of the existing corrugated tubes. To a certain extent, the deeper the depth between the crests and troughs, the better the flexibility of the corrugated tube. The depth between the crests and troughs of the corrugated tube of the present invention is 6-7 mm, and the flexibility of the corrugated tube is better, which is more conducive to the bending, expansion and rotation of the corrugated tube and the internal cables. Preferably, in one embodiment of the present invention, the depth between the crests and troughs is 6.08 mm.

[0032] The upper shell 101 and the lower shell 102 are buckled together along the length direction to form a U-shaped structure, including a curved portion 120, and straight portions 110 are arranged at at least one end of the two ends of the curved portion 120. Thus, the drag chain maintains the shape of the cable in a natural state.

[0033] The straight portion 110 and the curved portion 120 are both formed by buckling the upper shell 101 and the lower shell 102 along the length direction.

[0034] Specifically, alignment posts and alignment holes are respectively provided between the two mutually fitting side strips 103, and a plurality of clips and clip holes are evenly provided between the two mutually fitting side strips 103 along the length direction, the alignment posts enter into the alignment holes, and the clips enter into the clip holes.

[0035] Optionally, the alignment posts and the alignment holes on the two mutually fitting buckling side strips 103 correspond to each other one by one and are arranged alternately.

[0036] The improved bellows dust-free drag chain housing of the embodiment of the present invention comprises an upper shell and a lower shell. The outer sides of the upper shell and the lower shell are respectively provided with snap-fitting edge strips along the length direction. The corrugated top of each corrugated part forms a platform surface, so that the contact position A between the improved bellows dust-free drag chain housing and the bearing surface is surface contact, and the plane contact surface is larger. Experiments show that the contact fatigue strength with the external part is better, and the wear between the bearing surface is smaller; the platform surface of the corrugated top accounts for 20%-60% of the corrugated top, which can not only solve the problem of cutting wear caused by line contact between the contact position of the wave crest and the bearing surface, but also reduce the large plane area caused by The problems of large friction, large wear and high dust are solved; the corrugated side portions on both sides of the corrugated portion form a side plane, and the mutually squeezing position B between adjacent corrugated portions is also in surface contact. When cables are installed in the improved bellows dust-free drag chain housing, the improved bellows dust-free drag chain housing bends due to suspension and gravity, so that adjacent corrugated portions are squeezed against each other. The surface contact between adjacent corrugated portions is more conducive to reducing wear, improving force stability, and increasing bending resistance. The depth between the peaks and troughs of the bellows of the present invention is 6-7mm, the bellows has better softness, and is more conducive to the bending, expansion and contraction and rotation of the bellows and internal cables.

[0037] Preferably, a roller 210 is provided under the upper straight portion 110. The roller 210 can support the weight of the upper straight portion, reduce the bending and deformation of the corrugated tube and the internal cables, and can make the operation smoother and ensure the operation stability when the corrugated tube runs at high speed.

[0038] Preferably, a first detection unit 220 for detecting the cleanliness condition of the surface of the bellows dust-free drag chain shell is provided on the upper side of the motion trajectory of the upper straight portion 110. The first detection unit 220 is used to monitor the dirtiness of the surface of the bellows shell in real time, such as monitoring dust, oil, etc. The first detection unit 220 is electrically connected to the control device. When the dirtiness reaches a certain level, the control device controls the automatic cleaning of the upper and lower surfaces of the bellows shell to avoid dust, bacteria, oil, etc. accumulated on the surface of the bellows from adversely affecting the product.

[0042] The first clean conveying box 351 and the second clean conveying box 352 have the same structure.

The plurality of conveying rollers 401 can be driven to extend and retract separately or synchronously. When the conveying rollers 401 are retracted, the conveying rollers 401 are located below the surface of the clean box and do not contact the bellows. When the conveying rollers 401 are extended, the conveying rollers 401 are located above the surface of the clean box and contact the bellows. The dust suction port 402 is connected to a dust suction device, which can remove dust and other attachments on the surface of the bellows. Each decontamination and dehumidification unit 403 includes a box body, a dehumidification roller 4031 and a decontamination roller 4032. The dehumidification roller 4031 and the decontamination roller 4032 are both rotatably installed in the box body. The number and arrangement order of the dehumidification roller 4031 and the decontamination roller 4032 can be selectively set according to different situations.
