Description

Technical Field

[0001] The invention belongs to the technical field of hot-melt pipe welding, and in particular relates to a hot-melt pipe welding device in a water-flowing state. Background Art

[0002] With the continuous development of hot melt pipe welding technology, existing hot melt pipe welding devices have been widely used. However, these products still have some problems in actual use. For example, existing hot melt pipe welding devices usually have problems such as complex operation, low welding accuracy, and low degree of automation, which leads to specific problems such as low welding efficiency and unstable weld quality.

[0003] In order to solve these problems, there have been some attempts to improve welding quality and efficiency by improving the structural design and control mode of welding equipment. Although these methods have improved relevant aspects to a certain extent, they still have limitations, such as inaccurate temperature control during welding and inaccurate welding position alignment.

[0004] Specifically, after searching, a PPR pipe hot melt welding device with publication number CN110435162B was disclosed, and the publication date was 2021-08-24. The design adopts a combination of a moving rod and a heating head, and realizes the lateral movement and flipping of the heating head through the synergy of the first cylinder and the second cylinder. Although this design can improve the welding efficiency to a certain extent, since it relies on the mechanical action of the cylinder, there are the following problems: 1. The response speed and accuracy of the cylinder are limited, and it is difficult to achieve precise temperature control and position alignment; 2. The complexity of the mechanical action increases the maintenance cost and failure rate of the equipment. Therefore, this design cannot meet the application in welding scenarios with high precision and high automation requirements.

[0005] After searching, a PPR pipe hot melt welding equipment with a publication number of CN107322934B was disclosed, and the publication date was 2019-08-20. This product adopts a combination of a disassembly base and a hot melt die head, and realizes the rapid replacement of the hot melt die head through a snap-fit ​​part and a lock groove. Although this design can improve the flexibility and maintenance convenience of the equipment, it has the following problems because it relies on a mechanical locking mechanism: 1. The accuracy and reliability of the locking mechanism are limited, which can easily lead to deviations in the welding position; 2. Friction and wear during the mechanical locking process will reduce the service life of the equipment. Therefore, this design is difficult to meet the welding requirements for high precision and high reliability.

[0006] The above problems show that the hot melt pipe welding devices currently on the market are difficult to effectively cope with the new requirements for high-precision welding and high-automatic control under complex working conditions. Therefore, the present invention provides a hot melt pipe welding device in a water-flowing state to overcome these shortcomings and provide a new solution that is more intelligent, efficient and adaptable to changing environments.

[0059] The dynamic water temperature regulating controller 34 adjusts the temperature gradient of the cooling water in real time through a preset water temperature regulating algorithm according to the data collected by the temperature sensor in the welding area. When the temperature gradient in the welding area changes, the water temperature gradient sensor 35 monitors the temperature gradient in the welding area in real time and feeds back the data to the central processor 8. The central processor 8 sends instructions to the dynamic water temperature regulating controller 34 through the signal transceiver according to the change in the temperature gradient. The dynamic water temperature regulating controller 34 adjusts the temperature gradient of the cooling water in real time. The cooling pump and the second water temperature regulator 33 in the multi-stage cooling module 36 adjust the flow and temperature of the cooling water according to the instructions of the dynamic water temperature regulating controller 34. The intelligent cooling channel switching valve 37 switches the cooling water channel in real time according to the change in the temperature gradient in the welding area.

[0060] The multi-axis linkage controller 38 adjusts the positions of the heating head 12 and the cooling head 15 in real time according to the data collected by the position sensor through a preset multi-axis linkage alignment algorithm. When the welding position changes, the multi-axis linkage position sensor 40 monitors the positions of the heating head 12 and the cooling head 15 in real time and feeds back the data to the central processor 8. The central processor 8 sends instructions to the multi-axis linkage controller 38 through a signal transceiver according to the change in position. The multi-axis linkage controller 38 adjusts the positions of the heating head 12 and the cooling head 15 in real time to ensure the precise alignment of the welding position. The X-axis drive motor, the Y-axis drive motor and the Z-axis drive motor in the multi-axis linkage drive mechanism 39 adjust the position movement of the heating head 12 and the cooling head 15 in real time according to the instructions of the multi-axis linkage controller 38.

When the temperature distribution of the heating area changes, the integrated temperature sensor array 43 monitors the temperature distribution of the heating area in real time and feeds back the data to the central processor 8. The central processor 8 sends instructions to the integrated temperature control controller 42 through the signal transceiver according to the change in temperature distribution. The integrated temperature control controller 42 adjusts the power of the heating element in real time to ensure uniform heating effect at different positions.

[0062] Specific application scenarios

[0063] Assume that a hot melt pipe welding operation is required:

[0064] Step S1: Parameter setting

[0065] The operator inputs welding parameters (such as welding temperature, welding time, cooling water temperature, etc.) through the touch screen 22, and the touch screen 22 sends these parameters to the main control unit 1 through the signal transceiver.

[0066] Step S2: Loading

[0067] Place the hot melt pipe to be welded on the working table of the device and ensure that it is located below the heating head 12.

[0068] Step S3: Alignment

[0069] After receiving the alignment instruction, the main control unit 1 sends the instruction to the multi-axis linkage controller 38 through the signal transceiver. The multi-axis linkage controller 38 adjusts the positions of the heating head 12 and the cooling head 15 according to the data collected by the multi-axis linkage position sensor 40 to ensure that they are accurately aligned with the hot melt pipe to be welded.

[0070] Step S4: Preheating

[0071] After receiving the preheating instruction, the main control unit 1 sends the instruction to the integrated temperature control controller 42 through the signal transceiver. The integrated temperature control controller 42 adjusts the power of the heating element according to the data collected by the integrated temperature sensor array 43 to reach the preset welding temperature.

[0072] Step S5: Soldering

[0073] When the preset welding temperature is reached, the main control unit 1 starts the heating element to perform the welding operation and starts the dynamic water temperature adjustment system to ensure that the welding area is evenly heated and dissipated quickly.

[0074] Step S6: Cooling

[0075] After welding is completed, the main control unit 1 starts the dynamic water temperature adjustment system to quickly reduce the temperature of the welding area to ensure the welding quality.

[0076] Step S7: Cutting

[0077] The operator removes the hot melt pipe from the device after welding and carries out subsequent processing.
