Description
Technical Field
[0001] The invention relates to the technical field of aseptic pipe connection, in particular to an automatic aseptic pipe connection device with a seam detection function. Background Art
[0002] At present, the demand for aseptic pipetting in the biopharmaceutical industry is gradually increasing, and the standards are gradually improving. Therefore, the technology that relied on manual pipetting in the past can no longer adapt to the current standards.
[0003] During the pipe connection process, manual pipe connection is prone to contamination and the efficiency is uncontrollable, so automatic pipe connection equipment came into being. However, since medical pipes are mostly used for liquid storage and diversion, the pipe connection strength requirements are relatively high. Conventional pipe connection machines cannot automatically detect the pipes after welding and cannot guarantee the quality of the pipe connection. Summary of the invention
[0004] The object of the present invention is to provide an automatic aseptic pipe connection device with a seam detection function to solve the problems raised in the prior art.
[0005] To achieve the above object, the present invention provides the following technical solutions: An automatic aseptic pipe connection device with a seam detection function is used to weld two pipes. The automatic aseptic pipe connection device comprises a frame, a pipe connection machine, a detection device, a robot tooling, a pipe fixing device and a fixture quick-change station. Two pipe connection machines are arranged on the frame, and a pipe fixing device is arranged on one side of each pipe connection machine. The pipe fixing device is tightly connected to the frame. A detection device is arranged between the two pipe connection machines, and the detection device is tightly connected to the frame. A fixture quick-change station is arranged on the frame, and the robot tooling is tightly connected to the frame.
[0006] When welding two pipes, the frame serves as the main installation base for installing and fixing other devices. The pipe to be welded is positioned by the pipe fixing device. After positioning, the pipe is clamped by the robot tooling and sent to the pipe taking machine for automatic welding. After welding, the pipe is sent to the detection device by the robot tooling for automatic inspection of the welding quality. Multiple clamps are set in the clamp quick-change station to facilitate automatic replacement of clamps by the robot tooling, so as to adapt to the welding of pipes or other consumables of different specifications and improve the efficiency of pipe taking.
[0007] Furthermore, the pipe connection machine includes a mounting seat, a driving assembly, a cutting assembly and a cover body, the mounting seat and the frame are fastened, the cover body and the mounting seat are hinged, the driving assembly and the mounting seat are connected, the cutting assembly and the mounting seat are connected, the cutting assembly is used to cut off the pipeline, and the driving assembly is used to weld the cut pipeline; The driving assembly includes a fixed seat, a movable seat and an alignment cylinder. The fixed seat is tightly connected to the mounting seat. The mounting seat is provided with a slide groove, and the movable seat is placed in the slide groove. The alignment cylinder is tightly connected to the mounting seat, and the output end of the alignment cylinder is tightly connected to the movable seat.
[0008] The mounting base is fixed by a frame, and the cover body on the mounting base is hinged to control opening and closing. Two fixing grooves are respectively arranged on the fixed base and the movable base, which are respectively used to double fix the pipeline, so as to facilitate slitting and welding. The pipeline can be fixed by the existing clamp without too much restriction. When the two pipelines are respectively fixed on the fixed base and the movable base, the cover body is closed to facilitate aseptic pipe connection. The cutting component is used to cut the pipeline. After the cutting is completed, the displacement is output by the alignment cylinder to drive the movable base to move. Since the two fixing grooves on the fixed base and the movable base are respectively used to fix the pipeline, and the waste ends fall into a fixing groove of the fixed base and the movable base respectively, that is, after the cutting is completed, the two useful ends of the pipeline are staggered. The useful end on the movable base is driven to move by the alignment cylinder, so as to align with the useful end of the pipeline on the fixed base, so as to facilitate aseptic welding. The movable base is slidably guided for lateral movement by setting a slide groove.
[0009] Furthermore, the movable seat includes a base, an axle seat and a crimping cylinder, the output end of the alignment cylinder is tightly connected to the base, the crimping cylinder is tightly connected to the base, the output end of the crimping cylinder is tightly connected to the axle seat, and the axle seat and the base are slidably connected.
[0010] The movable seat is divided into a base for support and a shaft seat for fixing the pipe. The crimping cylinder is used to connect the base and the shaft seat, and the output direction is the same as the axial direction of the fixed pipe. When the pipe is welded, the radial force is applied by the crimping cylinder to increase the pressing force of the two pipe welding surfaces and improve the quality of the pipe connection.
[0011] Furthermore, the cut-off assembly includes a cut-off cylinder, two of which are respectively fastened to the mounting base, and the two cut-off cylinders are arranged facing each other, a heating base is arranged at the output end of the cut-off cylinder, a blade is arranged on the side of the heating base away from the cut-off cylinder, a heating surface is arranged on one side of the blade, and the heating surface is arranged obliquely; When heating: the heating surface is in contact with the welding surface of the pipe.
[0012] The two cutting cylinders are located on the upper and lower sides of the pipe to be cut, fixed by a mounting seat, and are used to drive the heating seat to move. The heating seat has a built-in heating wire for heating the blade. The adjacent surfaces of the two blades are defined as the inner side, and the opposite surfaces are defined as the outer side. The heating surface is located on the outer side. The local pressure is increased by the inclined arrangement, thereby improving the shearing efficiency. The inclined heating surface is far away from the cutting edge and the part with a large contact pressure with the pipe welding surface, and there are more hot-melted parts. The part close to the cutting edge has a small contact pressure with the pipe welding surface, and there are fewer hot-melted parts. The upper and lower blades move toward each other, thereby performing uneven hot melting on the pipe welding surfaces on both sides. After the welding is completed, the shaft seat is driven to move toward the fixed seat by the crimping cylinder, so that the welding amount of the pipe welding surface at the same height is equal, thereby improving the quality of the pipe connection.
[0013] Furthermore, the detection device includes a direction adjustment component, a light detection housing and a force-applying component. The light detection housing is tightly connected to the frame. The direction adjustment component and the force-applying component are respectively placed in the inner cavity of the light detection housing. The direction adjustment component includes two direction adjustment seats. The two direction adjustment seats are rotatably connected to the inner cavity of the light detection housing. The force-applying component includes an angle reduction rack, an angle reduction motor and an offset gear. Each direction adjustment seat is provided with an angle reduction rack. There are two offset gears. The two offset gears are rotatably connected to the light detection housing respectively. The tooth surfaces of the two offset gears are meshed. The two offset gears are meshed with the tooth surfaces of adjacent angle reduction racks. The angle reduction motor is tightly connected to the light detection housing. The output end of the angle reduction motor is tightly connected to the adjacent offset gears. The two offset gears are located at different floor heights respectively. The two angle reduction racks are staggered in the spatial direction, and the tooth surface of the angle reduction rack is half of the height. Initial state: two steering seats are arranged along the same straight line; During testing: the horizontal center lines of the two steering seats are arranged at an angle.
[0014] After the welding is completed, the finished pipe is sent into the inspection shell by the robot tooling for inspection. The two ends of the finished pipe are positioned respectively by two adjustment seats. The two adjustment seats rotate along the same axis, and one of the offset gears is driven to rotate by the angle motor. Since the tooth surface of the angle rack is half of its own height, the tooth surface of the offset gear is meshed near the middle layer. During the meshing process, the two angle racks are driven to move toward each other, that is, the rotation directions of the two adjustment seats are opposite. Through the opposite rotation directions of the adjustment seats, the two ends of the pipe are driven to bend inward. Since the welding surface of the finished pipe is located in the middle of the two adjustment seats in the initial state, that is, the center plane position, the inner side of the finished pipe is in a compressed state and the outer side is in a stretched state during the bending process, so that the quality of the finished pipe under the two-way force state can be inspected to improve the inspection accuracy.
[0015] Furthermore, the steering assembly also includes a clamping wheel, a steering groove is provided on the steering seat, a clamping wheel is provided in the middle section of the steering groove, the clamping wheel and the steering groove are rotatably connected, a clamping groove is provided on the clamping wheel, two steering motors are provided in the steering groove, and a driving gear is provided at the output end of the steering motor. The two driving gears are respectively located on both sides of the clamping wheel, and the tooth surfaces of the driving gear and the clamping wheel are meshed.
[0016] A clamping wheel is set in the middle of the steering groove of each steering seat, and the torque output by the steering motor drives the driving gear to rotate. Each clamping wheel is driven to rotate by the driving gears on both sides. The clamping wheel fixes the finished pipe through the clamping groove. The friction surface is set on the wall of the clamping groove to improve the transmission efficiency. When the pipeline is omnidirectionally inspected, the finished pipe is driven to rotate by the clamping wheels on both sides, so as to facilitate omnidirectional inspection of the finished pipe and improve the inspection quality. The slot of the clamping groove is smaller than the width between the two driving gears, so as to ensure that at least one driving gear can be used to drive the clamping wheel to rotate at the same time to avoid power interruption.
[0017] Furthermore, the detection device also includes a gap measuring assembly, which includes a lighting plate, a photosensitive layer and electrode columns. The lighting plate is tightly connected to the upper side of the inner cavity of the light detection shell, and the photosensitive layer is tightly connected to the lower side of the inner cavity of the light detection shell. The photosensitive layer is located on the light output path of the lighting plate. Two electrode columns are provided on the photosensitive layer, and the two electrode columns are electrically connected to two wiring terminals of the power supply respectively.
[0018] The quality of the pipe joint of the finished pipeline is detected by setting up a seam measuring component. The lighting board is used to emit light sources and illuminate the inside and outside of the finished pipeline at the same time, so as to detect the quality of the welding surface of the finished pipeline under pressure and tension. If the quality is up to standard, the light passes through the finished pipeline and illuminates the photosensitive layer, exciting electron-hole pairs, so that the circuit current composed of the electrode column and the power supply is the standard value. When the quality of the welding surface of the finished pipeline is unqualified, a gap is formed locally, that is, the light does not pass through the finished pipe joint. When the air light loss is negligible, no light loss is generated, that is, the light intensity irradiated on the photosensitive layer increases, and the circuit current increases, thereby automatically detecting the welding quality of the finished pipeline.
[0019] As an optimization, several photosensitive layers are provided, and several groups of photosensitive layers are provided along the horizontal radial direction of the pipeline welding surface. During the bending process, the welding surface is compressed on the inside and pulled on the outside. Several photosensitive layers are provided along the horizontal radial direction, so that the inner and outer layers of the photosensitive layers can be tested simultaneously. At the same time, multiple finished pipeline tests that can adapt to different specifications are provided.
[0020] Compared with the prior art, the present invention has the following beneficial effects: The inclined heating surface is far from the cutting edge and the contact pressure with the pipe welding surface is large, and the hot-melting part is more. The contact pressure with the pipe welding surface close to the cutting edge is small, and the hot-melting part is less. The upper and lower blades move toward each other, so that the pipe welding surfaces on both sides are unevenly hot-melted. After the welding is completed, the shaft seat is driven to move toward the fixed seat by the crimping cylinder, so that the cladding amount of the pipe welding surface at the same height is equal, thereby improving the quality of the pipe connection; because the tooth surface of the angled rack is half of its own height, the offset gear is meshed with the tooth surface at a position close to the middle layer. During the meshing process, the two angled racks are driven to move toward each other, that is, the rotation directions of the two adjustment seats are opposite, and the opposite rotation directions of the adjustment seats drive the two ends of the pipe to bend inward. Since the welding surface of the finished pipe is located in the middle of the two adjustment seats in the initial state, that is, the center surface position, the inner side of the finished pipe is in a compressed state and the outer side is in a stretched state during the bending process, so that the quality of the finished pipe under the state of bidirectional force can be detected, thereby improving the detection accuracy; when the pipeline is omnidirectionally detected, the finished pipe is driven to rotate by the clamping wheels on both sides, so as to facilitate omnidirectional detection of the finished pipe and improve the detection quality. When the quality of the welding surface of the finished pipe is unqualified, a gap is formed locally, that is, the light does not pass through the finished pipe. When the air light loss is negligible, no light loss is generated, that is, the light intensity irradiated on the photosensitive layer increases, and the circuit current increases, thereby automatically detecting the welding quality of the finished pipe.

[0028] The mounting seat 21 is fixed by the frame 1, and the cover body 24 on the mounting seat 21 is hinged to control opening and closing. Two fixing grooves are respectively arranged on the fixed seat 221 and the movable seat 222, which are used to double fix the pipeline, so as to facilitate cutting and welding. The existing clamps can be used to fix the pipeline without too much restriction. When the two pipelines are respectively fixed on the fixed seat 221 and the movable seat 222, the cover body 24 is closed to facilitate aseptic pipe connection.

The positioning cylinder 223 outputs displacement, driving the movable seat 222 to move. Since the two fixed grooves on the fixed seat 221 and the movable seat 222 are respectively used to fix the pipeline, and the waste ends fall into a fixed groove of the fixed seat 221 and the movable seat 222 respectively, that is, after the truncation is completed, the two useful ends of the pipeline are arranged in a staggered manner, and the useful end on the movable seat 222 is driven to move by the positioning cylinder 223, so as to align with the useful end of the pipeline on the fixed seat 221, which is convenient for aseptic welding, and the movable seat 222 is slidably guided for lateral movement by setting the slide groove 211.

[0032] The two cutting cylinders 231 are located at the upper and lower sides of the pipe to be cut, and are fixed by the mounting seat 21, and are used to drive the heating seat 232 to move. The heating seat 232 has a built-in heating wire for heating the blade 233. The adjacent surfaces of the two blades 233 are defined as the inner side, and the opposite surfaces are defined as the outer side. The heating surface 2331 is located on the outer side.

[0033] Furthermore, the detection device 3 includes a direction adjustment component 31, a light detection housing 32 and a force component 33. The light detection housing 32 is fastened to the frame 1. The direction adjustment component 31 and the force component 33 are respectively placed in the inner cavity of the light detection housing 32. The direction adjustment component 31 includes two direction adjustment seats 311, which are rotatably connected to the inner cavity of the light detection housing 32.

During the meshing process, the two angle racks 331 are driven to move toward each other, that is, the rotation directions of the two adjustment seats 311 are opposite. Through the opposite rotation directions of the adjustment seats 311, the two ends of the pipe are driven to bend inward. Since the welding surface of the finished pipe is located in the middle of the two adjustment seats 311 in the initial state, that is, the center plane position, during the bending process, the inner side of the finished pipe is in a compressed state and the outer side is in a stretched state, so that the quality of the finished pipe under the two-way force state is detected, thereby improving the detection accuracy.
[0035] Furthermore, the steering assembly 31 also includes a clamping wheel 312, a steering groove 3111 is provided on the steering seat 311, a clamping wheel 312 is provided in the middle section of the steering groove 3111, the clamping wheel 312 and the steering groove 3111 are rotatably connected, a clamping groove is provided on the clamping wheel 312, two steering motors 313 are provided in the steering groove 3111, and a driving gear 314 is provided at the output end of the steering motor 313, and the two driving gears 314 are respectively located on both sides of the clamping wheel 312, and the tooth surfaces of the driving gears 314 and the clamping wheel 312 are meshed.

The friction surface is arranged on the wall of the clamping groove to improve the transmission efficiency. When the pipeline is omnidirectionally detected, the finished pipeline is driven to rotate by the clamping wheels 312 on both sides, so as to facilitate omnidirectional detection of the finished pipeline and improve the detection quality. The notch of the clamping groove is smaller than the width between the two driving gears 314, so as to ensure that at least one driving gear 314 can be used to drive the clamping wheel 312 to rotate at the same time to avoid power interruption.

Two electrode columns 343 are provided on the photosensitive layer 342, and the two electrode columns 343 are electrically connected to two wiring terminals of the power supply respectively.
[0038] The quality of the pipe connection of the finished pipeline is detected by setting up the seam measuring component 34. The lighting plate 341 is used to emit light source and illuminate the inside and outside of the finished pipeline at the same time, so as to detect the quality of the welding surface of the finished pipeline under pressure and tension. If the quality is up to standard, the light passes through the finished pipeline and illuminates the photosensitive layer 342, exciting electron-hole pairs, so that the circuit current formed by the electrode column 343 and the power supply is the standard value. When the quality of the welding surface of the finished pipeline is unqualified, a gap is formed locally, that is, the light does not pass through the finished pipe connection. When the air light loss is negligible, no light loss is generated, that is, the light intensity irradiated on the photosensitive layer 342 increases, and the circuit current increases, so that the welding quality of the finished pipeline is automatically detected.
[0039] As an optimization, a plurality of photosensitive layers 342 are provided, and a plurality of photosensitive layers 342 are provided in a plurality of groups along the horizontal radial direction of the pipe welding surface. During the bending process, the welding surface is compressed on the inside and pulled on the outside, and a plurality of photosensitive layers 342 are provided along the horizontal radial direction, so that the inner layer and the outer layer of the photosensitive layer 342 are tested simultaneously, and at the same time, a plurality of finished pipe tests that can adapt to different specifications are provided.
[0040] The working principle of the present invention is as follows: the contact pressure between the inclined heating surface 2331 and the pipe welding surface is large and the hot-melting part is large, while the contact pressure between the part close to the cutting edge and the pipe welding surface is small and the hot-melting part is small. The upper and lower blades 233 move toward each other, thereby performing uneven hot-melting on the pipe welding surfaces on both sides. After the welding is completed, the crimping cylinder 2223 drives the shaft seat 2222 to move toward the fixed seat 221, so that the cladding amount of the pipe welding surfaces at the same height is equal, thereby improving the quality of the pipe connection. Since the tooth surface of the angled rack 331 is half of its own height, the offset gear 333 engages with the tooth surface at a position close to the middle layer. During the meshing process, the two angled racks 331 are driven to move toward each other, so that the two direction-adjusting seats 311 rotate in opposite directions. 311 rotates in the opposite direction, driving both ends of the pipeline to bend inward. Since the welding surface of the finished pipeline is located in the middle of the two adjustment seats 311 in the initial state, that is, the center surface position, the inner side of the finished pipeline is in a compressed state and the outer side is in a stretched state during the bending process, thereby detecting the quality of the finished pipeline under the state of bidirectional force application, thereby improving the detection accuracy; when the pipeline is omnidirectionally detected, the finished pipeline is driven to rotate by the clamping wheels 312 on both sides, thereby facilitating omnidirectional detection of the finished pipeline and improving the detection quality. When the quality of the welding surface of the finished pipeline is unqualified, a gap is formed locally, that is, the light does not pass through the finished pipe. When the air light loss is negligible, no light loss is generated, that is, the light intensity irradiated on the photosensitive layer 342 increases, and the circuit current increases, thereby automatically detecting the welding quality of the finished pipeline.
