Description

Technical Field

[0001] The utility model relates to the technical field of ultra-clean pipelines in the semiconductor industry, and particularly relates to an automatic clamping mechanism for ultra-clean steel pipes. Background Art

[0002] With the booming development of the semiconductor industry and the continuous progress of its related gas transmission technologies, more stringent requirements have been put forward for the accuracy, automation, and intelligence levels of production equipment. In the sub-field of gas transmission, the cutting of ultra-clean steel pipes, as a pre-process, is of great importance. The cutting efficiency and quality directly determine the quality and cost of the overall product chain, and have a profound impact on the performance and reliability of semiconductor devices.

[0003] At present, the common specifications of ultra-clean steel pipes on the market are diverse, such as 1 / 4 inch, 3 / 8 inch, and 1 / 2 inch, etc. These steel pipes have different lengths due to different application requirements. In the pre-cutting process, since the lengths of the incoming steel pipes vary, the length of the incoming materials cannot be predicted, and the products show diverse characteristics. In traditional cutting methods, the pipe fittings directly fall off after cutting. This method not only increases the labor intensity of the cutting personnel, but also easily damages the appearance of the pipeline components, affecting the quality and aesthetics of the products. At the same time, this manual operation method has low production efficiency and insufficient automation level, and it is difficult to meet the production requirements of high efficiency, high automation, and high precision in modern industry.

[0004] To address the above problems, there is an urgent need in the market for a mechanism that can automatically clamp ultra-clean pipe fittings to achieve automatic blanking and ensure the quality of the pipe wall. This mechanism needs to be able to intelligently identify pipe fittings of different lengths and automatically adjust the clamping method according to the length of the pipe fittings to ensure the stability and safety of the pipe fittings after cutting. At the same time, the mechanism also needs to have a high level of automation and intelligence to reduce the manual labor intensity and improve the production efficiency and quality stability.

[0005] However, there is currently no ultra-clean steel pipe automatic clamping mechanism on the market that can fully meet the above requirements. Therefore, the utility model proposes a new type of ultra-clean steel pipe automatic clamping mechanism, aiming to solve the problems existing in the prior art and provide more efficient and reliable production equipment for the gas transmission technology field in the semiconductor industry. Summary of the Utility Model

[0006] To solve the above problems, the utility model provides an automatic clamping mechanism for ultra-clean steel pipes. The automatic clamping mechanism for ultra-clean steel pipes realizes the automatic clamping of pipeline components with multiple length dimensions, provides a more convenient operation environment for automatic cutting; intelligently distinguishes the incoming length, selects different clamping methods to prevent the pipeline components from falling; reduces the manual labor intensity and improves the production efficiency and industrial automation level.

[0007] The technical solution of the present utility model is as follows:

[0008] An automatic clamping mechanism for ultra-clean steel pipes includes a short pipe rotating clamping mechanism, a pipe fitting length detection mechanism, and a long pipe auxiliary clamping mechanism. The pipe fitting length detection mechanism is used to detect the length of the incoming pipe fittings. The short pipe rotating clamping mechanism is used to clamp the pipe fittings with a length less than the set length. The long pipe auxiliary clamping mechanism is used to jointly clamp the pipe fittings with a length greater than the set length with the short pipe rotating clamping mechanism.

[0009] The short pipe rotating clamping mechanism includes a main body mounting plate, a rotating cylinder, a clamping cylinder II, and two jaws II. The base of the rotating cylinder is fixedly installed on one side of the main body mounting plate. The base of the clamping cylinder II is installed on the turntable of the rotating cylinder. The two jaws II are fixedly connected to the clamping arms of the clamping cylinder II.

[0010] The pipe fitting length detection mechanism is installed in the middle of the main body mounting plate.

[0011] The long pipe auxiliary clamping mechanism includes a telescopic cylinder mounting plate, a telescopic cylinder, a clamping cylinder I, and two jaws I. The telescopic cylinder mounting plate is fixedly installed on the other side of the main body mounting plate. The mounting seat of the telescopic cylinder is fixedly installed on the telescopic cylinder mounting plate. The base of the clamping cylinder I is fixedly installed on the piston rod of the telescopic cylinder. The two jaws I are fixedly connected to the clamping arms of the clamping cylinder I.

[0012] The pipe fitting length detection mechanism is a photoelectric inductor.

Rotary cylinder, 8. Clamping cylinder 2, 9. Claw 2, 10. Example steel pipe 1, 11. Example steel pipe 2. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] As Figure 1 and Figure 2 shown, the example steel pipe 10 and the example steel pipe 11 in the figure are only for illustration. The automatic clamping mechanism for ultra-clean steel pipes mainly consists of a short pipe rotary clamping mechanism, a pipe fitting length detection mechanism, and a long pipe auxiliary clamping mechanism.

[0025] The short pipe rotary clamping mechanism includes a main body mounting plate 5, a rotary cylinder 7, a clamping cylinder 2 8, and a claw 2 9.

[0026] The base of the rotary cylinder 7 is fixedly installed on one side of the main body mounting plate 5, the base of the clamping cylinder 2 8 is installed on the turntable of the rotary cylinder 7, and the two claws 2 9 are fixedly connected to the clamping arms of the clamping cylinder 2 8.

[0027] The short pipe rotating clamping machine is used to clamp pipe fittings with a length less than the set length (for example, 100 mm). According to the length of the incoming material, if the length of the pipe fitting is less than 15 mm, the rotating cylinder 7 drives the second jaw 9 to rotate to the end face of the pipe fitting for clamping, so as to increase the friction force and ensure firm clamping; if the length of the pipe fitting is between 15 mm and 100 mm, the second jaw 9 clamps the side wall surface of the pipe fitting.

[0028] The pipe fitting length detection mechanism is the photoelectric inductor 6.

[0029] The photoelectric inductor 6 is installed in the middle of the main body mounting plate 5.

[0030] The pipe fitting length detection mechanism is used to detect the length of the incoming pipe fittings. The photoelectric inductor 6 can accurately judge whether the length of the pipe fitting exceeds 100 mm and transmit the detection result to the PLC (programmable logic controller) for subsequent processing. At the same time, combined with the software system, the length of the incoming material is double-confirmed to improve the accuracy.

[0031] The long pipe auxiliary clamping mechanism includes a telescopic cylinder mounting plate 1, a telescopic cylinder 2, a first clamping cylinder 3 and a first jaw 4.

[0032] The telescopic cylinder mounting plate 1 is fixedly installed on the other side of the main body mounting plate 5. The mounting seat of the telescopic cylinder 2 is fixedly installed on the telescopic cylinder mounting plate 1. The base of the first clamping cylinder 3 is fixedly installed on the piston rod of the telescopic cylinder 2. The two first jaws 4 are fixedly connected to the clamping arms of the first clamping cylinder 3.

[0033] When the length of the incoming pipe fitting exceeds 100 mm, the photoelectric inductor 6 triggers a signal, the telescopic cylinder 2 extends, driving the first jaw 4 to move to the position of the pipe fitting. At the same time, the rotating cylinder 7 drives the second jaw 9 to rotate to the vertical direction, and jointly clamps the side wall surface of the pipe fitting with the first jaw 4 to achieve stable clamping of the long pipe.

[0034] Anti-slip textures or anti-slip coatings are provided on the inner surfaces of the first jaw 4 and the second jaw 9 to increase the friction force when clamping the pipe fitting and ensure firm clamping.

[0035] The utility model is convenient for subsequent automatic upgrading, can be matched with the previous automatic cutting equipment, further improve the detection efficiency, reduce the labor intensity of workers, and speed up the production rhythm.

[0036] Equipped with integrated software and cloud interconnection function, it can store a large amount of data after cutting and achieve efficient interconnection.

[0037] Operation process: The software system pre-distributes the length of the previous incoming material to the PLC; the photoelectric inductor 6 makes a secondary judgment on the length of the pipe fitting; according to the judgment result, the short pipe rotating clamping mechanism or the long pipe auxiliary clamping mechanism performs the clamping operation.

[0038] If the length of the pipe fitting is less than 15 mm, the second jaw 9 grips the end face of the short pipe; if the length of the pipe fitting is between 15 mm and 100 mm, the second jaw 9 grips the side wall of the pipe fitting; if the length of the pipe fitting exceeds 100 mm, the long pipe auxiliary clamping mechanism extends the first jaw 4 to jointly grip the side wall of the pipe fitting with the second jaw 9.

[0039] When the length of the ultra-clean steel pipe exceeds the rear long pipe jaw, the photoelectric sensor will sense it. At this time, the rotary cylinder will rotate the short pipe jaw to a direction parallel to the long pipe jaw, and at the same time, the telescopic cylinder will extend the short pipe jaw to the same height. The two jaws clamp simultaneously to ensure the clamping of the long pipe. When the length of the ultra-clean steel pipe does not reach the range of the photoelectric sensor, the system defaults it as a short pipe. The software system will transmit the length of the pipe fitting at this time, and drive the rotary cylinder to rotate the short pipe jaw to the direction of gripping the end face or the pipe wall of the short pipe. The length dimension of the pipe fitting can be changed within the software system to facilitate the clamping of short pipes within a certain range. For example, in this station, for pipe fittings with a length less than or equal to 15 mm, if the pipe wall is gripped after cutting, there will be a problem of loose gripping and dropping. At this time, the rotary cylinder will rotate to make the short pipe jaw grip its cutting end face, increasing the friction force to achieve the purpose of firm gripping.

[0040] The length dimensions of the long and short pipes in the present utility model (such as 100 mm and 15 mm) can be changed according to actual needs to facilitate the automatic clamping and blanking of most semiconductor pipe fittings after cutting on the market.

[0041] Through the coordinated work of the short pipe rotary clamping mechanism, the pipe fitting length detection mechanism, and the long pipe auxiliary clamping mechanism, the present utility model realizes the automatic clamping of ultra-clean steel pipes, improves production efficiency, reduces labor intensity, and has a wide application prospect.
