Abstract
Description
Technical Field
[0001] This invention relates to the field of shower pipe assembly, and more particularly to an automatic shower pipe assembly machine. Background Technology
[0002] The water-heated shower pipe is the core water supply component in the bathroom system that connects the "hot / cold water source" and the "shower head / faucet". Its main function is to accurately deliver hot, cold or mixed water to the shower terminal, while also adapting to the usage requirements of the shower scene. The automatic assembly machine for plumbing shower pipes is a specialized piece of equipment that uses mechanical transmission, pneumatic control, electrical programming, and visual inspection technology to automate the assembly of plumbing shower pipes (including pipe bodies, joints, sealing rings, valves, and other components). Its core function is to replace manual labor in completing the entire process of "component loading - positioning calibration - precise assembly - quality inspection - finished product unloading". It is suitable for large-scale production in the sanitary ware industry. In current automatic assembly machines for plumbing shower pipes, the installation of sealing rings typically involves feeding pre-sorted components to designated positions using a feeding tray, followed by a cylinder pushing the sealing ring onto the corresponding position on the pipe. However, in actual operation, when the cylinder begins pushing the sealing ring, interference may occur between the subsequent gasket and the cylinder or the already installed sealing ring. This interference can not only cause the gasket to jam, preventing it from proceeding to the next step, but in severe cases, it can even block the entire feeding system. In such situations, the machine must be stopped for manual inspection of the jammed or blocked parts before assembly can resume. This problem not only affects the efficiency of shower pipe assembly but also increases maintenance costs and downtime, negatively impacting production schedules and product quality. Therefore, an automatic assembly machine for plumbing shower pipes is designed. Summary of the Invention

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.
[0020] The following description is intended to disclose the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.
[0021] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are merely simplified descriptions for the convenience of describing this invention and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this invention.
[0022] It is understood that the term "a" should be understood as "at least one" or "one or more," that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.
[0023] Example 1: Please refer to Figure 1-13An automatic assembly machine for water-heated shower pipes includes a frame 1 and a material rack 2 fixed on the frame 1. The material rack 2 is equipped with a conveying mechanism 3, which is equipped with a plurality of pneumatic clamps 4. The conveying mechanism 3 is used to move the pneumatic clamps 4 horizontally. An installation frame 5 is fixed on the frame 1. An insertion unit 6 is provided on the installation frame 5. The insertion unit 6 is used to press the gasket onto the pipe end. A feeding vibratory plate 7 adapted to the insertion unit 6 is provided on the frame 1. A support plate 8 is fixed on the installation frame 5, and a positioning clamp 9 is fixed on the support plate 8. The positioning clamp 9 is located on one side of the insertion unit 6 and is used to clamp and position the pipe to ensure that the pipe maintains relative stability when the gasket is installed, and to prevent pipe displacement. Among them, the feeding vibratory plate 7 is an existing product. It periodically drives the vibratory plate body to make torsional linear vibration through electromagnetic force, which drives the material to move along the track. Through the spiral track and directional structure, the disordered material is sorted into a uniform posture. This is a conventional setting in this field, so it will not be described in detail here. It should be noted that the conveying mechanism 3 mainly consists of a linear guide rail, guide blocks and a cylinder. The cylinder drives multiple guide blocks to move on the linear guide rail, thereby driving multiple pneumatic grippers 4 to move synchronously, so as to achieve precise position control of the pneumatic gripper on a straight line. It should also be noted that the pneumatic clamp 4 is an existing product. It uses compressed air as power to clamp or release the pipe body during the assembly of the shower pipe. It is adapted to the needs of different workpiece sizes. This is a conventional setting in this field, so it will not be described in detail here. In this scheme, the tube is placed on the material carrier 2 and the support 10, and the pneumatic clamp 4 positions the tube. The pneumatic clamp 4 and the tube are then conveyed to the corresponding processing position by the conveying mechanism 3. The sealing gasket is pressed and installed on the tube port by the insertion unit 6. The tube then goes through the corresponding assembly process in sequence.
[0024] Furthermore, the insertion unit 6 includes: a support frame 11 slidably connected to the mounting frame 5, an installation tube 12 fixed on the support frame 11, a guide groove 42 opened on the mounting frame 5, and the support frame 11 slidably connected to the guide groove 42. The guide groove 42 guides the support frame 11 when it moves, ensuring that the support frame 11 maintains relative stability when it moves. A cylinder a13 is fixed on the support frame 11, and the output end of the cylinder a13 is slidably connected to the installation tube 12. A positioning mechanism 14 is provided on the installation tube 12. The positioning mechanism 14 is used to clamp and position the tube body. At least two mounting plates 15 are fixed on the mounting frame 5. A feeding mechanism 16 adapted to the installation tube 12 is provided on the mounting plate 15. The feeding mechanism 16 is used to feed the accessories on the feeding vibratory plate 7 into the installation tube 12. The mounting frame 5 is provided with a movable component 17 adapted to the support frame 11. The movable component 17 includes: a rotating shaft a18 rotatably connected to the mounting frame 5, at least two spur gears a19 fixed on the rotating shaft a18, and a servo motor 20 fixed on the mounting frame 5 coaxially with the rotating shaft a18; a toothed plate a21 meshing with the spur gears a19 fixed on the support frame 11; and a limiting block 43 fixed on the toothed plate a21, the length of which is greater than the tooth length of the toothed plate a21. The limiting block 43 is used to prevent the toothed plate a21 from disengaging from the spur gears due to excessive movement. Specifically, a guide wheel 44 is rotatably connected to the mounting frame 5, and the support frame 11 is slidably connected to the guide wheel 44. The guide wheel 44 is located between two toothed plates a21. By adding the guide wheel 44, it can not only provide guidance when the support frame 11 moves, but also share the load of the mounting frame 5, and avoid the support frame 11 from having too much sliding resistance with the guide groove 42 due to excessive weight. It should be noted that the servo motor 20 drives the rotating shaft a18 to rotate synchronously, which drives the spur gear a19 to rotate. The meshing transmission between the spur gear a19 and the toothed plate a21 drives the support frame 11 to move forward until the insertion unit 6 is moved forward to the preset position, and the insertion unit 6 presses the gasket onto the tube body. It should also be noted that by setting up the insertion unit 6, the gasket is able to fall into the designated position at a uniform speed and in a quantitative manner, and the cylinder a13 pushes the gasket to the tube port to complete the installation, avoiding jamming or even blockage during gasket feeding, and further improving the reliability of gasket installation.
[0025] Furthermore, the positioning mechanism 14 includes: a movable ring 22 slidably sleeved on the mounting tube 12, and a plurality of hinge seats 23 fixed on the mounting tube 12, a positioning gripper 24 rotatably connected to the hinge seat 23, and a connecting rod 25 hinged between the movable ring 22 and the positioning gripper 24; an electric push rod 26 is fixed to the mounting tube 12 by the mounting sleeve, and the other end of the electric push rod 26 is fixed to the movable ring 22. The movable ring 22 has at least two guide rods 45 fixed on it, and the mounting tube 12 has a guide block 46 through which the guide rods 45 pass. The guide block 46 has several sliders 47 fixed on it. The mounting tube 12 has a sliding groove 48 for the sliders 47 to slide and connect. The length of the guide rod 45 is greater than the length of the sliding groove 48. The guide rods 45 and the guide block 46 guide the movable ring 22 and ensure that the movable ring 22 maintains relative stability when subjected to force. The sliders 47 and the sliding groove 48 ensure that the movable ring 22 moves smoothly. It should be noted that the positioning mechanism 14 can accurately position the tube body, ensuring that the tube body maintains the necessary stability during the installation of the gasket. This measure effectively avoids the problem of tube body shaking that may occur during the gasket installation process, thereby greatly improving the efficiency of the assembly work. Through this design, the accuracy of gasket installation on the tube body is further improved. In this scheme, the positioning mechanism 14 is used to position the tube body. The principle is as follows: when the installation tube 12 comes into contact with the tube body, the electric push rod 26 intervenes to drive, and multiple positioning grippers 24 move towards the axis and flip simultaneously, thereby completing the clamping and positioning of the tube body.
[0026] Example 2: Please refer to Figure 9 - Figure 13 This embodiment further explains the first embodiment, the difference being the method of feeding the gasket.
[0027] Furthermore, the feeding mechanism 16 includes: a feeding pipe 28 rotatably connected to the mounting plate 15 via a rotating rod 27; a groove 29 communicating with the interior is provided on the mounting pipe 12, and the feeding pipe 28 is adapted to the groove 29; a spring plate 30 is fixed between the feeding pipe 28 and the mounting pipe 12; a mounting block 31 is fixed on the feeding pipe 28, and a rod 32 slides through the mounting block 31; at least two mounting blocks 33 are fixed on the rod 32; a blocking plate 34 is fixed on each of the two mounting blocks 31; a through groove 35 is provided on the feeding pipe 28 for the blocking plate 34 to pass through; a spring 36 is sleeved on the rod 32, and one end of the spring 36 is fixed to one of the mounting blocks 33. Another spring 36 is fixed to the mounting block 31. A toothed plate b37 is fixed on the rod body 32, and an additional plate 38 is fixed on the mounting bracket 5. A transmission shaft 39 is rotatably connected to the additional plate 38. A sector gear 40 that meshes with the toothed plate b37 is fixed on the transmission shaft 39. A drive motor 41 that is rotatably connected to the transmission shaft 39 is fixed on the additional plate 38. The output end of the cylinder a13 is chamfered at the end near the feeding pipe 28. The end of the feeding pipe 28 located inside the groove 29 is smooth arc surface. The chamfered surface of the output end of the cylinder a13 ensures that the feeding pipe 28 can be smoothly flipped after being subjected to force when the cylinder output end is squeezed by the feeding pipe 28. Specifically, both material blocking plates 34 are L-shaped. The length of the lower material blocking plate 34 is greater than that of the upper material blocking plate 34. The widths of the two material blocking plates 34 are the same. When feeding material into the mounting tube 12, the drive motor 41 precisely controls the transmission shaft 39 to rotate one revolution, thereby ensuring that a single gasket falls into the mounting tube 12. The feeding tube 28 is equipped with a photoelectric sensor, which is an existing product. It is used to detect whether there is material passing through the feeding tube 28. If there is a shortage of material, a signal is sent to the controller to ensure that when there is a shortage of material in the feeding tube 28, the moving part 17 drives the insertion unit 6 to reset to the initial position and continues to feed material into the feeding tube 28 by the feeding vibrating plate 7 and the track, ensuring accurate feeding. It should be noted that the feeding vibratory feeder 7 is equipped with a track, which is connected to the outlet of the feeding vibratory feeder 7. The track is an existing product and is located directly above the feeding pipe 28. The track is equipped with a matching material valve to control the feeding state in the track. When the feeding pipe 28 tilts, the material valve receives a signal and closes the track. When the feeding pipe 28 and the track are in a perpendicular alignment, the material valve opens and the components in the track enter the feeding pipe 28. It should also be noted that the feeding mechanism 16 enables precise control over the entry of the gaskets into the preset positions, ensuring that each gasket arrives at the designated position accurately. At the same time, during the pushing process, the feeding mechanism can effectively ensure that it is in a no-feeding state, avoiding the occurrence of jamming caused by feeding interference. This not only greatly improves the accuracy of gasket installation, but also significantly improves the smoothness and efficiency of the entire workflow, thereby effectively ensuring the stability of the assembly process and the reliability of product quality. In this scheme, the feeding mechanism for the gasket operates as follows: A cylinder a13 moves within the mounting tube 12. The compression transmission between the output end of cylinder a13 and the feeding tube 28 causes the feeding tube 28 to rotate along the axis of the rotating rod 27 under pressure. The elasticity of the spring plate 30 ensures that the feeding tube 28 remains in contact with the output end of cylinder a13. At this point, the feeding tube 28 is separated from the track. Cylinder a13 pushes the gasket onto the tube body, completing the pressing and installation of the gasket. Afterward, cylinder a13 returns to its initial position, and the feeding tube 28 springs back. Reset to the initial position to ensure that the feeding tube 28 and the mounting tube 12 are in contact. Driven by the drive motor 41, the transmission shaft 39 rotates synchronously, driving the sector gear 40 to rotate synchronously. Utilizing the meshing transmission between the sector gear 40 and the toothed plate b37, the rod 32 moves along the mounting block 31, causing the blocking plate 34 to move synchronously. Utilizing the elasticity of the spring 36, the rod 32 rebounds and resets, causing the rod 32 to move back and forth under force, so that the blocking plate 34 alternately passes through the through groove 35, thereby completing the unloading of the gasket.
[0028] In this solution, the process of pressing the gasket onto the pipe body is as follows: The first step is to use the pneumatic gripper 4 to deliver the tube to the predetermined position, and then use the positioning clamp 9 to perform secondary positioning and clamping on the tube. The second step is to move the insertion unit 6 forward to the predetermined position by the moving part 17 until the installation tube 12 fits with the tube body. Driven by the positioning mechanism 14, the positioning gripper 24 clamps and positions the tube body. The third step involves pushing the gasket towards the tube body via cylinder a13, feeding the gasket into the mounting tube 12 via the feeding mechanism 16, and pressing the gasket onto the tube body via cylinder a13.

The objectives of the present invention have been fully and effectively achieved.
