Beneficial effects

[0014] Compared with the prior art, the present invention has at least the following advantages:

[0015] 1. This utility model distributes four sets of tooling—a pipe fitting feeding device, a pressing mechanism, a welding device, and a four-sided seat unloading device—at four stations on the front, back, left, and right of a turntable. Each station corresponds to one of the four pressing material positioning seats. Through the coordination of a four-station divider, a rotary drive motor, a conveyor drive wheel, a conveyor driven wheel, and a conveyor belt, the turntable rotates intermittently. This causes the four pressing material positioning seats on the turntable to circulate sequentially between the pipe fitting feeding station, the four-sided seat feeding station, the pressing station, and the unloading station. This, combined with the material handling and feeding device, enables the feeding, pressing, and unloading of TO pipe fittings and four-sided seats. The entire pressing process is smooth, and the components are arranged in a reasonable and compact manner. The pressed BOSA components are then sent to the welding and marking stations for marking by the material handling and feeding device, and finally discharged to the receiving box. The entire process requires minimal manual intervention, resulting in a high degree of automation and high production efficiency.

[0016] 2. The assembly precision of the BOSA device of this utility model is achieved by using two sets of visual inspection mechanisms to inspect the incoming TO pipe fittings and the pressed BOSA device to ensure that the pressed finished product is qualified before it is transferred to the welding station.

[0017] 3. The welding torch of this utility model can be finely adjusted in the XYZ axis directions. The pre-pressed product is transported from the unloading station to the welding station for welding through the unloading and welding displacement rotation mechanism. The process is repeated, resulting in high welding efficiency.

[0018] 4. Before loading the TO fitting, use hand, foot, finger, and cylinder to gather all the pins of the TO fitting together, so that the TO fitting can be accurately inserted into the positioning hole of the press-fit material positioning seat, improving the accuracy and efficiency of assembly, and reducing insertion difficulties or positional deviations caused by pin misalignment or pin dispersion.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] See Figures 1-20This embodiment provides a BOSA automatic assembly and welding machine, including a frame 1. The top of the frame 1 is equipped with a four-sided seat discharge device 4, a pressing and fitting device 6, a pipe fitting feeding device 5, a welding device 7, a discharge device 8, and a material handling and feeding device 9. The pressing and fitting device 6 includes a pressing mechanism 61 and a rotary conveying mechanism 60. The rotary conveying mechanism 60 has pipe fitting feeding stations, pressing and fitting stations, unloading stations, and four-sided seat feeding stations respectively located at its front, rear, left, and right sides. The pressing and fitting mechanism 61 is located at the pressing and fitting station, the pipe fitting feeding device 5 is located at the pipe fitting feeding station, the welding device 7 is located at the unloading station, and the four-sided seat discharge device 4 is located at the four-sided seat feeding station. The material handling and feeding device 9 is located behind the four-sided seat discharge device 4, the pressing and fitting device 6, the welding device 7, and the discharge device 8. Two marking machines 15, corresponding to the positions of the discharge device 8, are installed on the rear side wall of the material handling and feeding device 9.

[0044] The rotary conveying mechanism 60 includes a four-station divider 605 mounted on the bottom of the top surface of the frame 1. The input end of the four-station divider 605 is connected to a driven wheel 603 of the conveying mechanism, and a rotary motor mounting plate 601 is fixed to one side of its input end. A rotary drive motor 600 is mounted on the rotary motor mounting plate 601, and the output shaft of the rotary drive motor 600 is connected to a driving wheel 602 of the conveying mechanism. The driving wheel 602 and the driven wheel 603 are connected via a conveyor belt 604. The output end of the four-station divider 605 is connected to a turntable 606 located above the top surface of the frame 1. When the rotary drive motor 600 is started, its output shaft rotates, causing the driving wheel 602 of the conveying mechanism to rotate as well. The rotation of the driving wheel 602 drives the conveyor belt 604, which in turn drives the driven wheel 603 to rotate. The rotation of the driven wheel 603 of the conveying mechanism drives the input shaft of the four-station divider 605 to rotate. When the input shaft rotates, the four-station divider 605 converts the continuous rotational motion into intermittent rotational motion, causing the turntable 606 to rotate 90° each time. This facilitates corresponding operations such as TO fitting loading, square seat loading, pressing of TO fittings and square seats, and finished product unloading.

[0045] The top of the turntable 606 has four evenly distributed pressing material positioning seats 607. Under the action of the four-station divider 605, the rotation of the pressing material positioning seats 607 is intermittent, pausing for a period of time after each 90° rotation. The turntable is driven by a rotary drive motor 600 to cycle between the four positions: pipe loading station, square seat loading station, pressing station, and unloading station.

[0046] In this utility model, a rotary joint 608 is provided in the middle of the turntable 606, which is a prior art product; the pressing material positioning seat 607 includes a TO positioning seat 6071, which is rotatably connected to the turntable 606 via a lower bearing 6076; a fixture limiting flange 6070 mounted on the turntable 606 is sleeved on the outer side of the TO positioning seat 6071, and the bottom of the fixture limiting flange 6070 is rotatably connected to the TO positioning seat 6071 via an upper bearing 6075; a convex ring 60710 is provided in the middle of the TO positioning seat 6071, and the upper bearing 6075 is located below the convex ring 60710. A TO clamping seat 6074 is provided on the top outer side of the TO positioning seat 6071. A bushing 6072 is provided between the bottom of the TO clamping seat 6074 and the TO positioning seat 6071. A spring 6073 is sleeved on the bottom of the bushing 6072, located between the convex ring 60710 and the bushing 6072. The TO clamping seat 6074 can float under the action of the spring 6073. The top ends of the TO clamping seat 6074 and the positioning seat 6071 pass through the fixture limiting flange 6070, and the bottom end of the TO clamping seat 6074 is locked onto the top and bottom surfaces of the fixture limiting flange 6070 under the action of the spring 6073. The top of the TO clamping seat 6074 has an opening, and a square seat placement platform 60740 is provided along the inner edge of the opening. The top of the TO positioning seat 6071 is located at the opening, and the top of the TO positioning seat 6071 has a recessed platform 60711. There is a movable gap between the top surface of the recessed platform 60711 and the top and bottom surfaces of the TO clamping seat 84. The movable gap between the top surface of the recessed platform 60711 and the top and bottom surfaces of the TO clamping seat 84 is a floating space. The TO positioning seat 6071 has a positioning hole 6079 and an air passage 6078 from top to bottom, which are connected. The bottom of the TO positioning seat 6071 passes downward through the turntable 606 and is connected to a first rotary joint 6077. The outer surface of the rotary joint 608 is connected to four quick connectors 6080 for connecting to an external vacuum source. The bottom of the rotary joint 6081 has four second rotary joints 6081. The second rotary joints 6081 and the first rotary joints 6077 are connected by air pipes. When the external vacuum source is connected via a rotary joint, the air tube will not entangle or twist during the rotation of the turntable 606, ensuring that the vacuum adsorption function is not affected by the rotation. When the TO tube is placed on the TO positioning seat 6071, its tube feet extend into the positioning hole 6079, and the tube body is located at the top of the TO positioning seat 6071, the external vacuum source is activated to perform vacuum adsorption on the TO tube.

[0047] The pressing mechanism 61 includes a mounting frame 610 mounted on a frame 1. A first shelf 618 and a second shelf 619 are spaced apart in the hollow portion of the mounting frame 610. A screw 611 is rotatably connected to the top of the first shelf 618 and the bottom of the second shelf 619. A pressing drive motor 617 is mounted on the bottom of the second shelf 619. The motor shaft of the pressing drive motor 617 is vertically upward and connected to the bottom end of the screw 611 via a coupling. A pressing screw block 615 is threaded onto 611; pressing slide rails 613 are respectively provided on the front walls of both sides of the mounting frame 610, and pressing slide blocks 614 are slidably connected to the pressing slide rails 613; pressing movable plates 612 are fixed on the outer walls of the two pressing slide blocks 614, and the pressing movable plates 612 have through holes 6120. The pressing screw block 615 extends outward and passes through the through holes 6120, and a pressing frustum 616 is provided at its outer bottom. The pressing drive motor 617 works, driving the pressing screw block 615 to move downward, and the pressing movable plate 612 moves downward accordingly. The through holes 6120 limit the movement of the pressing screw block 615. As the pressing screw block 615 moves downward, the pressing frustum presses together the TO pipe fitting and the square seat placed on the pressing material positioning seat 607 on the turntable 606, which is currently located at the pressing station. During the pressing process, the square seat 18 is positioned on the square seat placement platform 60740 on the TO clamping seat 84, and the TO fitting 22 is positioned on top of the TO positioning seat 6071. Since there may be dimensional errors and positional deviations between the TO fitting 22 and the square seat 21 during processing and assembly, the floating TO clamping seat 6074 can automatically adjust its position according to the actual situation, ensuring better alignment and fit between the square seat 21 and the TO fitting 22 during the pressing process, avoiding assembly difficulties or damage caused by positional deviations. In addition, during pressing, the TO clamping seat 6074 can move downwards to buffer some of the pressure, preventing the fitting or square seat from deforming, cracking, or damaging its surface due to excessive impact, thus protecting the integrity and performance of the parts.

The limiting guide groove 460 and the receiving notch 4800 cooperate to form a space to receive the square seat. When the square seat 21 on the linear vibrating track 42 falls into the receiving notch 4800 of the first gripper 480, the first gripper 480 and the second gripper 481 then close, clamping the square seat 21 within the receiving notch 4800. Subsequently, the square seat rotating cylinder 45 rotates, causing the square seat finger cylinder 48 to rotate 90 degrees in the opposite direction to a vertical position, ensuring that the mounting hole of the square seat 21 to be assembled faces downwards. The limiting rod 46, with its upper limit guide groove 460, limits the square seat 21, preventing it from slipping off from the left side when clamped by the square seat finger cylinder 48. Simultaneously, the limiting guide groove 460 does not obstruct the rotation of the square seat finger cylinder 48.

[0058] The working principle of this utility model is as follows: A circular vibrating plate 40 automatically arranges the square seats 21 and maintains a specific discharge direction. Vibration by a straight vibrator 41 transports the square seats 21 along a straight vibrating track 42 to the receiving notch 4800 of the square seat finger cylinder 48, which is horizontal and has its fingers open. Then, the finger cylinder 48 closes, and the first gripper 480 and the second gripper 481 clamp the two sides of the square seat 21.

Figure 5The material is shown in the loading posture. The pipe fitting loading device 5 picks up the TO pipe fitting and retracts its legs, and positions and photographs it using the vision inspection device 11 to adjust the TO pipe fitting to the correct loading posture. Then, the TO pipe fitting 22 with the adjusted posture is placed on the pressing material positioning seat 607, which is currently located at the pipe fitting loading station; the four-station divider 605 rotates to transport the pressing material positioning seat 607, which is loaded with the TO pipe fitting 22, to the square seat loading station.

The pressing screw block 615 of the pressing mechanism 61 moves downward, and the pressing table 616 presses the TO fitting 22 and square seat 21, which are now located on the pressing material positioning seat 607 on the turntable 606, together, so that the TO fitting 22 is pressed into the square seat 21 to form a BOSA device. Subsequently, the four-station divider 605 rotates the pressing material positioning seat 607 loaded with BOSA devices to the unloading station. Through the unloading and welding displacement rotation mechanism 13, the pressed BOSA device is transported to the vision inspection mechanism 11 to determine whether the angle is qualified. Unqualified products will be rejected and will not be transferred to the welding and marking process. Qualified products are placed onto welding positioning seats 74 on the welding device 7 by the unloading and welding displacement rotation mechanism 13.
