[0002] In the new energy development industry, solar photovoltaics, semiconductor chips, battery energy storage, and lithium batteries all involve the transportation of pure water and liquid medicines. These industries place high demands on piping systems, and even higher demands on the transportation systems themselves. For example, when it comes to the material selection of ultrapure water, ultrapure water system pipelines are often made of fluoropolymer pipes (such as PP and PVDF). Correspondingly, the requirements for welding processes are even more stringent. Due to the actual application requirements of the industry, many pipe welding processes and process directions have very specific requirements.

[0003] During pipe welding construction, it is often necessary to connect pipe joints to pipelines through welding. However, in existing technologies, most of them are manually welded by socket welding. First, the pipe and the joint are heated to melt the pipe and the joint, and then the pipe and the joint are connected. After cooling, the pipe and the joint are bonded together. Manual socket welding is not only labor-intensive and inefficient, but also easily leads to loose pipe welding and inaccurate positioning, which affects the welding quality and cannot meet the requirements of high-end industry pipeline systems.

DETAILED DESCRIPTION

[0028] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments, and the following embodiments do not limit the utility model involved in the claims. In addition, not all combinations of features described in the embodiments are necessarily required for the solution of the utility model.

[0029] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments. Example

[0030] like Figure 1 As shown, a pipe joint welding device is used to weld a joint 1 to a pipe 2. The joint 1 here is a pipe joint 1, which is similar to a small section of pipe and is used to communicate with the pipe 2.

[0031] The welding equipment includes a joint welding module, and the joint welding module includes a feeding device, a conveying device and a picking and placing device.

[0032] The feeding device includes a feeding barrel 3 for conveying the connector 1 and a discharge end 4 for outputting the connectors 1 one by one outward; the feeding barrel 3 can be used to cooperate with a vibrating loading plate, etc., so that the connector 1 is conveyed along the feeding barrel 3, and a control valve 5 for controlling the opening and closing of the nozzle of the discharge pipe is provided at the discharge end 4, thereby controlling whether the connector 1 is output or not.

[0033] The picking and placing device includes a first clamping member 6 for clamping the joint 1 and a first telescopic device 7 for controlling the extension and retraction of the first clamping member 6 relative to the pipe 2; the clamping member in this embodiment is a three-jaw chuck, and of course other types of automated clamps such as mechanical claws can also be used to grasp the joint 1, and the first telescopic device 7 is a cylinder.

[0034] The conveying device includes a carrier and a rotating device 10 for controlling the rotation of the carrier. The carrier is provided with a carrier position for carrying the connector 1, and the carrier position includes a positioning hole 9 for inserting the connector 1. The carrier in this embodiment is a plate 8, one end of which is connected to the rotating shaft of the rotating device 10, and the other end is provided with the positioning hole 9. The positioning hole 9 is a hole provided on the plate 8. The carrier is provided with a heating element, and the heating element is used to heat the connector 1 on the carrier position. For example, an electric heating device such as a resistance heater can be provided around the positioning hole 9 to heat the connector 1 located in the positioning hole 9, so that the part to be connected can reach the temperature at which it is welded to the pipe 2. The rotating device 10 can be, for example, a motor.

[0035] The rotating device 10 causes the carrier to rotate around the rotating axis, so that the carrier position corresponds to the discharge end 4 of the feeding device or to the first clamping member of the picking and placing device; that is, the distance from the rotating axis to the positioning hole 9 is equal to the distance from the rotating axis to the discharge end and equal to the distance from the rotating axis to the first clamping member 6.

[0036] The bearing member and the rotating device 10 are controlled to extend and retract relative to the discharge end 4 by a second telescopic device 11 so that the positioning hole 9 is close to the discharge end 4 for receiving the joint 1. The second telescopic device 11 is a cylinder.

[0037] When the positioning hole 9 rotates to below the discharge end 4, the control valve 5 opens to allow one of the connectors 1 to fall into the positioning hole 9, and then the control valve 5 closes. Then the heating element heats the connector 1 in the positioning hole 9 and simultaneously causes the plate body 8 to rotate around the rotating shaft so that the connector 1 on the positioning hole 9 rotates to below the first clamping member 6. Then the first clamping member extends toward the connector 1 at the positioning hole 9 so that the connector 1 enters the claw or the second telescopic device 11 causes the connector 1 at the positioning hole 9 to enter the claw upward, thereby achieving the claw's grasping of the connector 1. Then the rotating device 10 causes the plate body 8 to rotate so that the plate body 8 leaves the first clamping member 6 and then rotates to the bottom of the discharge end 4 to receive the next connector 1. After the plate body 8 leaves the first clamping member 6, the second telescopic device 11 can cause the claw to extend toward the upper pipe 2 so that the connector 1 on the claw contacts the pipe 2, thereby causing the connector 1 to be welded to the pipe 2.

[0038] Because the connector 1 of this embodiment needs to communicate with the pipe 2, a plurality of through-holes 201 are formed on the sidewall of the pipe 2. The connector 1 needs to be welded to the through-holes 201 to achieve communication between the through-holes 201 and the pipe 2. To this end, the device of this embodiment further includes a punching module 12 capable of drilling holes in the sidewall of the pipe 2. The punching module 12 of this embodiment includes an electric drill capable of drilling holes in the sidewall of the pipe 2 and a displacement control mechanism 121 for controlling the multi-degree-of-freedom movement of the electric drill, thereby controlling the movement trajectory of the drill bit 122 of the electric drill.

[0039] like Figure 3 、 4 As shown in Figure 5, the welding equipment also includes a first guide rail 13 arranged along the length direction of the pipeline 2. The joint welding module is slidably fitted on the first guide rail 13, so that the position of the welding module relative to the pipeline 2 can be adjusted to facilitate welding the joint 1 to different positions of the pipeline 2 as needed.

[0040] like Figure 2 、 6 As shown in FIG. 7 , the first guide rail 13 is also slidably engaged with the punching module 12, so that the position of the punching module 12 relative to the pipe 2 can be adjusted to facilitate punching holes at different positions of the pipe 2 as needed. A rack 133 is provided on the first guide rail 13, and the punching module 12 and the welding module are provided with a gear 20 meshing with the rack 133 and a motor driving the gear 20 to rotate.

[0041] At least two joint welding modules are slidably provided on the first guide rail. Different joint welding modules are used for welding joints of different sizes. In this embodiment, two are provided, one of which is suitable for joints with a pipe diameter of 20 mm and the other is suitable for joints with a pipe diameter of 25 mm.

[0042] The left end of the first guide rail 13 is a temporary storage position for the punching module 12, and the right end is a temporary storage position 132 for the welding module, so as to facilitate the temporary docking of the welding module.

[0043] The welding equipment further includes a pipe 2 positioning device for supporting and positioning the pipe 2. The pipe 2 positioning device includes several supporting members arranged along the length direction of the pipe 2. In this embodiment, seven supporting members are arranged.

[0044] The support member includes two relatively movable clamping parts 14 for clamping the pipe 2. The clamping parts 14 have a contoured surface that matches the outer contour of the pipe 2. The distance between the two support parts can be adjusted by a cylinder or the like to adapt to the clamping and positioning of pipes 2 with different diameters.

[0045] The support portion has a contoured surface that matches the outer contour of the pipe 2 , that is, the support portion has an arcuate surface for supporting the pipe 2 so that the surface of the support portion fits the outer wall of the pipe 2 .

[0046] like Figure 8 As shown, the pipeline 2 positioning device also includes a second guide rail 15, and several bearing blocks are slidably arranged on the second guide rail 15, so that the spacing of the support members can be adjusted along the second guide rail 15 to adapt to the use of pipelines 2 of different lengths.

[0047] The second guide rail 15 includes at least two parallel support rails, and a debris collection box 16 is provided below the support rails. In this embodiment, there are two parallel support rails, and the space between the two support rails is the upper port 17 of the debris collection box 16. When the pipe 2 is drilled, the generated debris will fall downward from the upper port 17 into the debris collection box 16.

[0048] Pipe end positioning devices for fixing the ends of the pipe 2 are respectively provided at the two ends of the pipe 2, thereby preventing the pipe 2 from moving in the length direction of the pipe 2.

[0049] The pipe end positioning device includes a second clamping member 18 for clamping the end of the pipe 2 and a height adjustment mechanism 19 for adjusting the height of the second clamping member 18 relative to the support member. The second clamping member 18 can also be a chuck or other clamp for fixing the end of the pipe body. The height adjustment mechanism 19 can be a cylinder linear motor, etc., so that it can be used for pipes 2 of different diameters.

[0050] The pipe end positioning device at at least one end is slidably positioned with the second guide rail 15. In this embodiment, the height adjustment mechanism 19 of the left-end pipe end positioning device is fixedly connected to the end of the support rail, and the right-end pipe end positioning device is slidably arranged on the support rail, thereby adjusting the distance between the two pipe end positioning devices to accommodate the positioning of pipes 2 of different lengths. A positioning pin, clamping mechanism, etc. can be provided between the pipe end positioning device and the support rail to facilitate temporary fixation of the pipe end positioning device relative to the support rail.

[0051] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0052] Although some terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention. The execution order of actions, steps, etc. in the devices and methods shown in the specification and drawings can be implemented in any order as long as there is no special explicit limitation on the order and as long as the output of the previous processing is not used in the subsequent processing. Similar sequential terms (for example, "first", "next", "secondly", "again", "then", etc.) used for the convenience of description do not mean that they must be implemented in such an order.

[0053] It should be understood by those skilled in the art that all directional references (for example, above, below, upward, up, downward, down, top, bottom, left, right, vertical, horizontal, etc.) are used descriptively in the drawings to facilitate the reader's understanding, and do not represent limitations (for example, on position, orientation or use, etc.) on the scope of the present invention as defined by the appended claims. They are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. The directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0054] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0055] In addition, some vague terms (e.g., "substantially," "certainly," "substantially," etc.) may refer to slight inaccuracies or deviations in conditions, quantities, values, or dimensions, some of which are within manufacturing variations or tolerances. It should be noted that the use of terms such as "first" and "second" to define components is solely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meanings and should not be construed as limiting the scope of protection of this application.
