Description

Technical Field

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

[0002] With the rapid development of the semiconductor industry and its related gas transmission technology, higher and higher requirements are placed on the precision and automation level of production equipment. Especially in the gas transmission sub-industry, the cutting of ultra-clean steel pipes is one of the key processes, and its production efficiency and cutting quality directly affect the quality and cost of the overall product. At present, the common ultra-clean steel pipes on the market mainly have three different diameter specifications of 1 / 4, 3 / 8, and 1 / 2. During the automated cutting process of these steel pipes, due to the fixed center height of the cutting head and the different diameters of the steel pipes, it is difficult for the steel pipe axis to remain coaxial with the cutting head axis, which in turn affects the cutting accuracy and quality.

[0003] In order to be compatible with the cutting of steel pipes of different diameters, the traditional method often requires manual adjustment of the axis height of the steel pipe, which not only increases the labor intensity of the operator, but also easily leads to inaccurate coaxiality due to human factors, thus causing cutting quality problems. In addition, frequent manual adjustments also reduce production efficiency, making it difficult to meet the needs of modern industrial production for efficiency and precision.

[0004] In view of the above problems, there is an urgent need in the market for a device that can automatically adjust the height of the steel pipe axis to meet the cutting requirements of different pipe diameters. Utility Model Content

[0005] In order to solve the above problems, the utility model provides an ultra-clean steel pipe height automatic adjustment device, which can complete the automated integration of steel pipe cutting, reduce manual labor intensity, improve efficiency and stabilize quality.

[0006] The technical solution of the utility model is as follows:

[0007] An automatic height adjustment device for ultra-clean steel pipes comprises a base plate, a V-shaped groove, a height adjustment mechanism and a driving mechanism. The base plate is a long plate-shaped structure. A set of height adjustment mechanisms are respectively arranged at both ends of the base plate. Two V-shaped grooves are respectively installed on two sets of height adjustment mechanisms. The height is adjusted by the height adjustment mechanisms. The steel pipe is placed in the V-shaped groove. The driving mechanism is installed on the base plate to drive the height adjustment mechanism to perform the height adjustment action.

[0008] The height adjustment mechanism includes a V-groove sliding seat, a V-groove sliding linear guide and a guide rail bracket. The guide rail bracket is fixedly mounted on the base plate. The V-groove sliding linear guide includes a vertical guide rail and a slider that slides up and down along the guide rail. The guide rail of the V-groove sliding linear guide is fixedly mounted on the guide rail bracket. The V-groove sliding seat is fixedly mounted on the slider of the V-groove sliding linear guide. The V-groove is fixedly mounted on the V-groove sliding seat.

A servo connecting plate is fixedly connected to a slider of the servo module. The sliding direction of the slider of the servo module is parallel to the steel pipe. An optical axis is fixedly connected to the servo connecting plate. The servo module drives the optical axis to move linearly in a horizontal direction. A transmission mechanism is arranged between the optical axis and a V-groove sliding seat. The transmission mechanism converts the horizontal linear movement of the optical axis into the vertical linear movement of the V-groove sliding seat.

[0010] The optical axis is fixedly mounted on the servo connecting plate through an axis clamp.

[0011] The transmission mechanism includes a cam plate and a cam follower. A cam groove inclined from high to low is arranged on the cam plate. One end of the cam follower is fixedly connected to the V-groove sliding seat, and the other end of the cam follower is rollingly inserted in the cam groove. The cam plate is installed on the base plate for horizontal linear movement, and the moving direction of the cam plate is consistent with the optical axis.

DETAILED DESCRIPTION

[0023] like Figures 1 to 3 As shown, the ultra-clean steel pipe automatic height adjustment device is mainly composed of a base plate 1, a V-shaped groove 5, a height adjustment mechanism and a driving mechanism.

[0024] The bottom plate 1 is designed as a long strip structure to ensure the stability and support of the whole device. A set of height adjustment mechanisms are respectively provided at both ends of the bottom plate 1, and the two sets of height adjustment mechanisms jointly adjust the height of the V-shaped groove 5 thereon to adapt to steel pipes 9 of different diameters.

[0025] The height adjustment mechanism includes a V-groove sliding seat 6, a V-groove sliding linear guide 7 and a guide rail bracket 8. The guide rail bracket 8 is firmly mounted on the base plate 1 as a support base for the V-groove sliding linear guide 7. The V-groove sliding linear guide 7 includes a guide rail portion in the vertical direction and a slider portion that can slide linearly up and down along the guide rail. The guide rail portion is fixed on the guide rail bracket 8, and the V-groove sliding seat 6 is fixedly mounted on the slider of the guide rail, thereby realizing the free movement of the V-groove sliding seat 6 in the vertical direction. The V-groove 5 is mounted on the V-groove sliding seat 6 for placing and fixing the steel pipe 9 to be cut.

[0026] The driving mechanism is composed of a servo module 11 and a transmission mechanism. The servo module 11 is firmly mounted on the base plate 1, and the high-precision motor and transmission device inside it can provide stable and accurate power output. A servo connecting plate 10 is fixedly connected to the slider of the servo module 11, and the servo connecting plate 10 moves with the movement of the slider. The optical axis 12 is firmly mounted on the servo connecting plate 10 through the shaft clamp 2 to ensure that it moves horizontally in a straight line with the drive of the servo module 11.

[0027] In order to realize the conversion from the horizontal movement of the optical axis 12 to the vertical movement of the V-groove sliding seat 6, the present device is specially designed with a transmission mechanism. The transmission mechanism is composed of a cam plate 3 and a cam follower 4. The cam plate 3 is processed with a cam groove inclined from high to low. This design enables the cam plate 3 to produce a displacement change in the vertical direction when the cam groove moves horizontally. One end of the cam follower 4 is fixedly connected to the V-groove sliding seat 6, and the other end is rollably inserted into the cam groove with its rolling end. Therefore, when the cam plate 3 moves in the horizontal direction, the inclined surface of the cam groove will push the rolling end of the cam follower 4 to move up and down, thereby driving the V-groove sliding seat 6 and the V-groove 5 thereon to move in the vertical direction.

[0028] In order to ensure that the cam plate 3 can move smoothly and accurately, the device is equipped with a transverse guide rail 13 on the bottom plate 1. The cam plate 3 is fixedly connected to the optical axis 12 through a pipe clamp, and is also fixedly connected to the slider of the transverse guide rail 13. In this way, when the servo module 11 drives the optical axis 12 to move, the cam plate 3 can move linearly in the horizontal direction along the transverse guide rail 13, thereby driving the transmission mechanism to adjust the height of the V-shaped groove 5.

[0029] Furthermore, in order to facilitate subsequent automation upgrades, automatic cutting equipment can be used to achieve automatic adjustment of the height of the steel pipe, adjust different axis heights according to different pipe diameters, stabilize production quality, and reduce manual labor intensity.

[0030] The ultra-clean steel pipe height automatic adjustment device drives the optical axis 12 to move horizontally through the servo module 11. The optical axis 12 is connected to the cam plate 3, so that the cam plate can move horizontally on the transverse guide rail 13. The cam groove on the cam plate 3 cooperates with the cam follower 4, so that the cam follower 4 moves in the groove, and the V-groove moves up and down on the V-groove sliding linear guide rail 7, so as to realize automatic height adjustment of the steel pipe 9.

[0031] The ultra-clean steel pipe height automatic adjustment device provides significant technical effects for the precision and automation requirements of ultra-clean steel pipe cutting in the semiconductor industry and its related gas transmission technology, which are specifically reflected in the following aspects:

[0032] Improve cutting accuracy and quality: By automatically adjusting the axis height of the steel pipe, it ensures that the axis of steel pipes of different diameters (such as 1 / 4, 3 / 8, 1 / 2, etc.) can maintain precise coaxiality with the axis of the cutting head during the cutting process, thereby effectively avoiding cutting quality problems caused by inaccurate coaxiality and significantly improving cutting accuracy and consistency.

[0033] Improve production efficiency: The automated adjustment process replaces the traditional manual adjustment, which not only reduces the labor intensity of operators, but also avoids adjustment errors and frequent adjustment time caused by human factors, thereby greatly improving production efficiency and meeting the needs of modern industrial production for efficiency and precision.

[0034] Enhanced adaptability and flexibility: The device is designed with a height adjustment mechanism and a drive mechanism, which can easily cope with ultra-clean steel pipes of different diameters. It can achieve fast and accurate axis height adjustment without changing equipment or making complex adjustments, enhancing the adaptability and flexibility of the production line.

[0035] Ensure the cleanliness of the production environment: The use of automated adjustment methods reduces the interference of manual operations on the production environment, helps maintain the cleanliness of the ultra-clean steel pipe production environment, and further improves product quality.

[0036] Reduce maintenance costs: The automatic adjustment mechanism is reasonably designed, compact in structure, and easy to maintain and service, which reduces equipment failure rate and maintenance costs and extends equipment service life.
