Description

TECHNICAL FIELD

[0001] The present application belongs to the field of industry, and particularly relates to a diaphragm chamber and clamp block mounting equipment of a differential pressure transmitter. BACKGROUND

[0002] The differential pressure transmitter is a transmitter for measuring the pressure difference between two ends of the transmitter, and outputting a standard signal (such as 4-20 mA, 0-5 V). The differential pressure transmitter is different from the general pressure transmitter in that it has two pressure interfaces. The differential pressure transmitter is generally divided into a positive pressure end and a negative pressure end, which also makes the transmitter have measuring diaphragms at both ends. At present, the structures of almost all differential pressure transmitters are to weld two bases to form a diaphragm chamber having measuring diaphragms at both sides, and to mount clamp blocks corresponding in structure to both sides of the diaphragm chamber.

[0003] At present, the common clamp block mounting mode of the diaphragm chamber is as follows: one of the clamp blocks is placed on a workbench, and the diaphragm chamber is placed on one side of the clamp block by judging the alignment by the naked eye, and then the other clamp block is placed on the other side of the diaphragm chamber by judging the alignment by the naked eye. Finally, the whole clamp block-diaphragm chamber-clamp block assembly is fastened by screws. This process is time-consuming and inaccurate because the alignment is judged by the naked eye. In this process, the diaphragms at both sides are easily damaged due to the operator's mistake, so that the whole diaphragm chamber becomes a waste product. SUMMARY

At the same time, because the step of moving the clamp block above the diaphragm membrane is avoided in the whole process, the risk of bumping the membrane due to human error is greatly reduced. Since all differential pressure transmitters on the market today use similar structures, the present embodiment can be slightly changed in size for different brands and models of differential pressure transmitters to achieve the purpose of application.

[0043] Referring to Figures 1 to 4 The present embodiment provides a diaphragm and clamp block mounting device of a differential pressure transmitter. From the main body, it includes a detection system 1, a sorting system 2, an installation system 3, a conveyor belt 4 and a sorting platform 5.

[0044] The detection system 1 is built-in laser camera, the detection system 1 is used for sending in the clamp block from the outside, through the laser camera shooting and automatically distinguishing the internal finish and size of the clamp block, if unqualified, it is rejected, and the qualified clamp block is sent to the discharge port of the detection system 1;The sorting system 2 is used for transporting the qualified clamp block to the installation system 3;The installation system 3 is used for assembling the qualified clamp block with the diaphragm box of the differential pressure transmitter;The conveying belt 4 is connected with the installation system 3 and the sorting platform 5, which is used for conveying the assembled differential pressure transmitter to the sorting platform 5;The sorting platform 5 is used for receiving the assembled differential pressure transmitter from the installation system 3 to carry out sorting, and selecting the qualified product.

[0045] Specifically, referring to Figure 2 , the detection system 1 includes a feeding track 101, an automatic clamping mechanical arm 102, a first laser camera 103, a transverse track and a waste box 104. A plurality of clamp block grooves are arranged on the feeding track 101, and the clamp block is put into the corresponding clamp block groove to input into the detection system 1 from the outside.

Similarly, a plurality of clamp block grooves are also arranged on the transverse track, and the automatic clamping mechanical arm 102 will put the clamp block into the corresponding clamp block groove and move along the transverse track. The first laser camera 103 is arranged above the moving direction of the transverse track, during which the clamp block slides along the guide rail and the corresponding clamp block groove and passes through the fixed first laser camera 103, and the first laser camera 103 and its detection system 1 will automatically distinguish the internal finish and size of the clamp block. The unqualified clamp block will be automatically slid to the waste box 104 on one side of the transverse track.
