Description

Technical Field

[0001] The present invention relates to the field of pipe fitting assembly, and in particular to a visual tee assembly machine. Background Art

[0002] For the installation of a two-way, three-way joint or valve in the middle of a plastic pipe fitting, it is necessary to butt-assemble, that is, plastic pipe fittings need to be assembled at both ends of a two-way, three-way joint or valve, such as the butt-assembly of a one-way valve, the assembly of a three-way joint, the assembly of a muffler and a filter, etc. Since they have a common assembly process that requires pipe fittings to be assembled at both ends, this type of equipment is habitually called a three-way assembly machine. Place the pipe fitting or valve on the middle profiling tooling, then clamp the pipe fittings on the left and right sides, and then butt-assemble. Due to material problems, some plastic pipe fittings need to be expanded first during assembly, and then the joints will be assembled more smoothly.

[0003] Most of the current equipment is manually assembled. Generally, quick clamps are used to clamp the plastic pipe fittings on both sides. The pipe joints or valves are placed on the middle positioning block, and then the levers on both sides are pulled by hand to make the clamps installed on the guide rails on both sides squeeze and assemble in the middle. There is also a step-by-step assembly, that is, install the plastic pipe fittings on one side first, and then install the other side; manual assembly is performed on the modified bench drill, which will save a little effort, but the efficiency is lower. Purchase bench drill equipment for modification, remove the motor, belt and control circuit on the bench drill, retain the lifting and manual pressing handle of the bench drill, and use the pressing stroke handle. Because it is a lever principle, all operations are more labor-saving. Install the contour positioning block of the workpiece joint on the drill chuck of the bench drill, and then make two clamps and install them on the base of the bench drill. A clamping cylinder is installed on the clamp, and the plastic pipe fitting is placed in the middle of the clamp, pneumatic clamping, and the bench drill handle is manually pulled to drive the pipe joint to press down, and the assembly of the pipe joint is completed.

[0004] After the plastic pipe fittings are connected, if the pipe fittings are cracked, they are unqualified. If the insertion stroke of the joint is too small or too large, it is unqualified. If it is too small, the strength cannot meet the requirements and it is easy to leak. If it is too large, it will cause leakage in the expansion gap of the pipe fittings. These quality problems can only be controlled by quality training of assembly personnel.

[0005] If there is a problem with the assembly quality of automobile pipelines with two-way, three-way and valves, it will affect the entire pipeline system in the car, causing the failure of many related components, posing a very serious safety hazard or directly leading to an accident.

[0031] The clamping mechanism 300 includes an upper module 310 and a lower module 320 for clamping pipe fittings. The upper module 310 and the lower module 320 are arranged up and down. The upper module 310 is movably installed, and the lower module 320 is fixedly installed. The upper module 310 is in two states. One is a working state in which the upper module 310 is attached to the lower module 320 to clamp the pipe fitting, and the other is a separated state in which the upper module 310 is away from the lower module 320 to loosen the pipe fitting.

[0032] A clamping groove 311 with a semicircular cross-section is provided on the opposite sides of the upper module 310 and the lower module 320. The clamping groove 311 matches the pipe fitting, and the groove direction of the clamping groove 311 is consistent with the length direction of the working panel 100. When the upper module 310 is in the working state, the pipe fitting is clamped in the area enclosed by the two clamping grooves 311.

[0033] The upper module 310 is detachably mounted on the clamp 350, and the lower module 320 is detachably mounted on the lower clamp seat 360. The lower clamp seat 360 is fixedly mounted, and the clamp 350 is movably mounted. The clamp 350 is connected to the A safety component 340 and the adjustment component 330. The A safety component 340 is used to drive the clamp 350 to drive the upper module 310 downward to fit on the lower module 320. When the upper module 310 fits on the lower module 320, the A safety component 340 triggers the adjustment component 330. The adjustment component 330 is used to load the load on the upper module 310 to clamp the pipe fitting.

[0036] The A safety component 340 includes an A magnetic switch, a guide rod 342 and an A spring 341. The guide rod 342 is arranged in the vertical direction. The upper end of the guide rod 342 is fixed on the lower clamp seat 360, and the lower end of the guide rod 342 passes through the connecting plate 333. The A spring 341 is sleeved on the guide rod 342. The A spring 341 is located between the lower clamp seat 360 and the connecting plate 333. Both ends of the A spring 341 abut against the lower clamp seat 360 and the connecting plate 333. The A spring 341 is used to apply a downward elastic force to the connecting plate 333, so that the clamping jaw 350 has a tendency to move downward. The A magnetic switch is installed on the A telescopic member 334. When the A spring 341 drives the clamping jaw 350 to move downward to the position where the upper module 310 is attached to the lower module 320, the movable end of the A telescopic member 334 extends to the position of triggering the A magnetic switch. The A magnetic switch starts the A telescopic member 334 to extend, thereby realizing the function of applying a load to the clamping jaw 350.

[0037] A buffer ring 335 is installed at the connection between the movable end of the telescopic member 334 and the connecting plate 333 .

[0038] The pressing mechanism 400 includes a B slider 420 and a B linear guide 410. The B linear guide 410 is arranged along the length direction of the working panel 100. The B slider 420 is slidably assembled on the B linear guide 410. The lower clamping seat 360 is fixedly installed on the B slider 420. The B slider 420 is connected to the output rod of the electric cylinder 430 through a connecting head, and the electric cylinder 430 is connected to the servo motor 440.

[0039] The intermediate mechanism 200 includes a C slider 220 and a C linear guide 210. The C linear guide 210 is arranged along the width direction of the working panel 100. The C slider 220 is slidably assembled on the C linear guide 210. The C slider 220 is fixedly installed on the intermediate seat 230. The intermediate seat 230 is fixedly installed on the working panel 100. One end of the C linear guide 210 is connected to the B telescopic member 240. The fixed end of the B telescopic member 240 is installed on the working panel 100. The telescopic direction of the B telescopic member 240 is consistent with the width direction of the working panel 100. The movable end of the B telescopic member 240 is installed on the C linear guide 210. Two expansion heads 500 are arranged on the upper side of the C linear guide 210. The C linear guide 210 is also equipped with a clamp 250 for clamping joints or valves.

[0040] The fixture 250 includes an upper intermediate module 251 and a lower intermediate module 252 arranged in a vertical direction and an L-shaped mounting seat 253 arranged in a vertical shape. The L-shaped mounting seat 253 is fixedly mounted on the C linear guide rail 210 through an A transition plate 255. Two expansion heads 500 are mounted on both sides of the L-shaped mounting seat 253. A C telescopic member 254 is also mounted on the L-shaped mounting seat 253. The C telescopic member 254 is arranged in a vertical direction. The fixed end of the C telescopic member 254 is mounted on the L-shaped mounting seat 253. The movable end of the C telescopic member 254 is connected to the upper intermediate module 251 through a B transition plate 256. The lower intermediate module 252 is fixedly mounted on the A transition plate 255.

[0041] The L-shaped mounting seat 253 is also provided with a B safety component 260, which is used to drive the B transition plate 256 to drive the middle upper module 251 downward to fit on the middle lower module 252. When the middle upper module 251 fits on the middle lower module 252, the joint or valve is clamped, and the B safety component 260 triggers the C telescopic member 254, which extends to apply a load to the B transition plate 256 and the middle upper module 251, thereby clamping the joint or valve.

[0042] The B safety component 260 includes a B magnetic switch and a B spring 261. A circular hole 262 is provided on the L-shaped mounting seat 253 along the vertical direction. A slot hole communicating with the outside is provided in the lower half of the circular hole 262. A B spring 261 is installed in the circular hole 262. The elastic direction of the B spring 261 is consistent with the hole direction of the circular hole 262. A cover plate 263 is installed on the upper end of the circular hole 262. The inner plate surface of the cover plate 263 abuts against the upper end of the B spring 261. The B transition plate 256 extends into the slot hole and is connected to the lower end of the B spring 261. The B spring 261 is always in a compressed state and applies a downward elastic force to the B transition plate 256. The B magnetic switch is installed on the C telescopic member 254.

[0043] The A telescopic member 334, the B telescopic member 240 and the C telescopic member 254 are all cylinders;

[0044] The working panel 100 is also equipped with a visual inspection mechanism, which includes a display 110. An industrial camera 120 is installed below the display 110. The camera head of the industrial camera 120 points to the pressing area where the intermediate mechanism 200 is located. A background light source 130 is installed below the pressing area. The display 110 is also equipped with a keyboard 112 and a control button 111.

[0045] The present invention has 6 assembly modes: left assembly, right assembly, two-end assembly, left flaring assembly, right flaring assembly, and two-end flaring assembly, that is, the equipment can be assembled on both sides at the same time or on one side.

[0046] Assembly process: Place the connector or valve on the middle lower module - Place the plastic pipe fittings on one side in turn, trigger the switch on the other side to clamp - Move the left and right mechanisms in the center for assembly - All clamping mechanisms automatically release - Remove the finished pipe fittings - Trigger the switch mechanism to reset.

[0047] The expansion assembly process is as follows: place the connector or valve on the middle lower module - place the plastic pipe fittings on one side in turn, trigger the switch on the other side to clamp - the left and right mechanisms move in the center to expand the pipe fittings - the left and right mechanisms return to the original position - the shifting mechanism moves backward to the press-fitting position - the left and right mechanisms move in the center to assemble the plastic pipe fittings - all clamping mechanisms are automatically released - remove the finished plastic pipe fittings - trigger the switch mechanism to reset.

[0048] The equipment of the present invention adopts a steel profile frame with 4 casters installed at the bottom for easy movement and fixation. The electric control system is installed in the box. The left and right pressing mechanisms are installed on the back of the working panel 100 and hidden inside the box. Makeshift holes are designed on the working panel 100 to leave makeshift gaps for the movement of assembly components. At the same time, protective plates are installed on both sides of the assembly components to prevent fingers from being pinched by the gap. This method can effectively avoid the safety of operators and keep the table top clean and tidy. There is no complicated mechanism on the table top, so there is no safety hazard, and it is conducive to on-site management.

[0049] The display 110 is installed at the upper rear of the working panel 100, which is convenient for the operator to observe. The box is also equipped with operation buttons, which are separated from the control buttons 111, that is, the equipment startup, shutdown, buzzer alarm, etc. are installed below the display 110, and the assembled trigger button, reset, and emergency stop are installed on the operating edge of the equipment for easy operation. The keyboard 112 is installed at the lower right corner of the display 110. It uses a keyboard and is equipped with a wireless mouse to make the device more sophisticated.

[0050] The clamping mechanisms 300 on the left and right sides of the middle mechanism 200 are used to clamp the plastic pipe clamping mechanism on the left and the plastic pipe on the right. The left and right clamping mechanisms 300 are completely symmetrical mechanical structures. Only one side of the structure is introduced here, which is mainly used for clamping plastic pipes to complete the docking assembly with the middle two-way joint or valve. The upper module 310 is installed on the clamping claw 350, and the lower module 320 is installed on the lower clamping seat 360. Both adopt the dovetail groove matching structure to realize the quick change of the upper and lower modules to adapt to pipes of different sizes. The clamping claw 350 is installed on the A linear guide 331, and the A slider 332 of the A linear guide 331 is fixed. On the lower clamping seat 360, the lower part of the clamping jaw 350 is connected to the piston rod of the A telescopic member 334 through the connecting plate 333, so that the A telescopic member 334 can drive the clamping jaw 350 to move up and down to realize the opening and closing of the upper and lower modules; the A telescopic member 334 is composed of a cylinder, called a clamping cylinder. The advantage of this structure is that the upper and lower modules are installed on the same positioning block, that is, on the lower clamping seat 360. In this way, there is no transition piece connection, and the processing and installation accuracy are easier to ensure. In addition, during the working process, since the upper and lower modules are subjected to a large lateral force, the upper and lower modules are prone to misalignment. This method can solve the misalignment problem of the upper and lower modules.

[0051] The clamping cylinder is installed on the B slider 420, and a buffer ring 335 is installed on its piston rod. When the clamping cylinder piston rod is quickly retracted, that is, during the opening process of the clamping jaw 350, it plays a buffering role. The guide rod 342 is fixed on the B slider 420, and the guide rod 342 passes through the spring pressure plate at the bottom of the mounting clamping jaw 350. The spring pressure plate is fixedly installed on the connecting plate 33, and the A spring 341 is sleeved on the guide rod 342. With this method, the clamping cylinder is not ventilated, that is, the solenoid valve is in the middle leakage position, under the action of the spring force of the A spring 341 Down, pull out the piston rod of the clamping cylinder, and at the same time drive the clamping claw 350 to close; at this time, the A magnetic switch installed on the clamping cylinder has a signal output; that is, the upper and lower modules are in a completely closed state, which means that there is no foreign matter (including fingers) between the upper and lower modules. If there is a foreign matter on the upper and lower modules, the clamping claw 350 cannot close the upper and lower modules under the action of the spring force, and the A magnetic switch on the clamping cylinder has no signal output. When the computer receives the A magnetic switch signal, it starts to ventilate and load the clamping cylinder. This principle is the anti-pinch finger function.

[0052] The function of the press-fitting mechanism 400 is to expand and press-fit the plastic pipes on the left and right sides. Its structure is completely symmetrical. Only one side of the mechanism is introduced here. The above-mentioned B slider 420 is actually a moving part of the press-fitting mechanism 400. The entire clamping mechanism 300 is installed on the B slider 420. Driven by the B slider 420, the clamping mechanism 300 can move left and right. The B slider 420 is connected to the B linear guide 410, and a double guide slider is used, one on each side. The B linear guide 410 is shared by the left and right press-fitting mechanisms.

[0053] At the same time, the B slider 420 is connected to the output rod of the electric cylinder 430 through a connector. To prevent the influence of eccentric force, the connector adopts a T-shaped gap structure. The electric cylinder 430 is controlled by a servo motor 440 to extend and retract the output rod. The electric cylinder 430 is installed on the working panel 100, so that the electric cylinder drives the movement of the clamping mechanism 300 to realize the expansion and pressing of the pipe fitting.

[0054] Servo motor 400 is used for press-fitting, with low noise, strong controllability, large output force, fast speed and high efficiency. The press-fitting stroke, return position, flaring stroke and speed, flaring retraction position and other parameters of two-way connectors or valves of different specifications can be set.

[0055] The intermediate mechanism 200 has three functions: one is position switching, i.e. switching between flaring and pressing; the second is installation positioning and clamping of joints or valves; and the third is anti-pinching function. The A transition plate 255 is installed on the C linear guide 210, while the C slider 220 of the C linear guide 210 is installed on the middle seat 230, which is fixed on the working panel 100. The piston rod of the B telescopic member 240 is connected to the C linear guide 210 through a connecting block and a floating joint. The B telescopic member 240 is fixed on the working panel 100 by a cylinder mounting plate. The extension and retraction of the piston rod of the B telescopic member drives the A transition plate to move forward and backward; thereby driving the upper module 251, the lower module 252 and the expansion head 500 of the superstructure to move forward and backward, realizing the position switching of the flaring and pressing functions of the plastic pipe fittings on both sides. The lower module 252 is used for the installation and positioning of pipe joints or valves.
