Description

Technical Field

[0002] A flow meter is an instrument that indicates the measured flow rate and / or the total amount of fluid in a selected time interval. Flow meters are divided into differential pressure flow meters, rotor flow meters, throttling flow meters, slit flow meters, volumetric flow meters, electromagnetic flow meters, ultrasonic flow meters, etc. according to their measurement principles.

[0003] Among them, the electromagnetic flowmeter uses the principle of electromagnetic induction to measure the flow rate of conductive fluids based on the electromotive force generated when the conductive fluid passes through an external magnetic field. The structure of an electromagnetic flowmeter is usually a measuring tube with an induction electrode installed. The measuring tube and the induction electrode usually need to be produced separately and then assembled. This production method is not only inefficient, but also in the long-term use process, due to the wear of the measuring tube and the probe, and the thermal expansion and contraction between the two, the gap between the measuring tube and the probe will expand, resulting in leakage, electrode short circuit and housing moisture, causing the detection accuracy of the flowmeter to decrease.

The first vacuum suction cup 650 is driven by the first screw conveying device 610 and the second screw conveying device 630 to embed the fixed mold 320 into the upper part of the two mold cores 310; A first flipping mechanism 700 is disposed on the right side of the first biaxial displacement assembly 600. The first flipping mechanism 700 is used to flip the two mold cores 310 and the fixed mold 320. The slide rail 110 is also provided with a third slideway 140 connected to the second slideway 130. The two mold cores 310 and the fixed mold 320 are driven by the conveying mechanism 400 to slide from left to right along the third slideway 140. A primary molding mechanism 800 is disposed on the right side of the first flipping mechanism 700. The primary molding mechanism 800 includes a third cylinder 810 and a first injection machine 820 disposed on the workbench 100. The piston rod of the third cylinder 810 is connected to the first movable mold 330. The first injection machine 820 is connected to the first movable mold 330 through a first connecting pipe 830. The first movable mold 330 is driven to press against the fixed mold 320 by the third cylinder 810, and the material is injected into the mold mechanism 300 by the first injection machine 820 and the first connecting pipe 830, so as to mold the measuring tube 210; The first flipping mechanism 700 includes a slide 710 and a second cylinder 720 disposed on the workbench 100. The piston rod of the second cylinder 720 is connected to the slide 710. Two first clamping assemblies 730 are symmetrically disposed on the slide 710. The first clamping assembly 730 includes a first mounting seat 731 rotatably disposed on the slide 710, two first clamps 732 are slidably disposed on the first mounting seat 731, a first hollow rod 733 is further disposed on the first mounting seat 731, a first guide rod 734 is slidably disposed on the first hollow rod 733, a first guide groove 735 is opened on the workbench 100, and the first guide rod 734 is slidably connected in the first guide groove 735; The first clamping assembly 730 further includes two first connecting rods 736, one end of each of the two first connecting rods 736 is movably hinged to the first guide rod 734 through a hinge shaft, and the other end of each of the two first connecting rods 736 is movably hinged to the two first clamps 732 through a hinge shaft. A gear 740 is disposed on each of the two first hollow rods 733 , and two racks 750 are symmetrically disposed on the workbench 100 . The two gears 740 are meshed with the two racks 750 , respectively.

[0038] In this embodiment: first, along the slope on the left side of the slide rail 110, several groups of mold cores 310 can be transported to the right side at equal distances, and each group of mold cores 310 is composed of two symmetrical front and rear mold cores 310. Considering the special shape of the flow meter 200, two tapered mold cores 310 are selected to form the internal structure of the mold.

[0039] The two mold cores 310 slide down along the first slideway 120, fall between the first set of second clamps 422, are clamped and transported to the right, and stop when they reach the position of the two first cylinders 500. The two first cylinders 500 push the two mold cores 310 to slide toward each other and join together along the connecting part of the first slideway 120 and the second slideway 130. Then the belt conveyor 410 continues to transport the two mold cores 310 to slide to the right along the second slideway 130 and stop at the first dual-axis displacement assembly 600.

[0040] Another set of belt conveyors 410 may be provided at the rear side of the workbench 100 to convey a plurality of fixed molds 320 at equal intervals, and the first vacuum suction cup 650 may be controlled to move in the front-back and up-down directions by the first screw conveyor 610 and the second screw conveyor 630 to adsorb a fixed mold 320 and place it on the two mold cores 310. The first screw conveyor 610 and the second screw conveyor 630 may be composed of a motor, a screw, a nut, etc., and the first vacuum suction cup 650 may be connected to a vacuum pump to generate suction force for grasping objects through the operation of the vacuum pump. The above-mentioned are conventional technical means and will not be described in detail.

[0041] The middle of the fixed mold 320 has a truncated cone-shaped protrusion, which abuts against the two mold cores 310 to form a shape consistent with the sensing electrode 230. When the belt conveyor 410 continues to drive the two mold cores 310 and the fixed mold 320 to move to the right along the third slide 140 to the first flipping mechanism 700, the second cylinder 720 drives the slide 710 to keep moving synchronously with the belt conveyor 410. In this process, the initial state is as follows Fig.10 The two first clamps 732 shown in the figure will first rotate clockwise while clamping the two mold cores 310 and the fixed mold 320, and then rotate 180° while maintaining the clamping state. The two first clamps 732 will then move away from each other to release the two mold cores 310 and the fixed mold 320, thereby flipping the fixed mold 320 to the lower side.

[0042] Specifically, in Figure 4 and Figure 5 Taking a group of first clamping assemblies 730 located at the rear side as an example, the first guide rod 734 slides to the right along the trapezoidal first guide groove 735, and firstly moves backward under the guidance of the first guide groove 735, and the two first clamps 732 are brought closer to each other through the transmission of the two first connecting rods 736, and then the first guide rod 734 moves along the horizontal part of the first guide groove 735, and then the first guide rod 734 moves forward under the guidance of the first guide groove 735, so that the two first clamps 732 are separated from each other. At the same time, during this process, the gear 740 rolls along the rack 750, so that the first guide rod 734, the first hollow rod 733 and the first mounting seat 731 rotate.

[0043] After turning over, the belt conveyor 410 continues to convey so that the two mold cores 310 and the fixed mold 320 stop at the primary molding mechanism 800, and the third cylinder 810 drives the first movable mold 330 to move down and assemble on the fixed mold 320. The first movable mold 330 has the same structure as the fixed mold 320 and also has a truncated cone-shaped protrusion. Then the first injection machine 820 selects different forms of raw materials according to the material of the measuring tube 210 and injects them into the gap between the fixed mold 320, the first movable mold 330 and the two mold cores 310 to form a measuring tube 210 with two reserved holes 220. The primary molding mechanism 800 can select different types of equipment according to different conveying materials, as a conventional technical means, it will not be described in detail.

[0044] In addition, during the conveying process, before reaching the first flipping mechanism 700, as shown in FIG. Figure 6 As shown, the second guide groove 425 corresponds to a lower portion of the first slideway 120 to the portion before the first flipping mechanism 700, and a higher portion of the portion after the inclined section corresponding to the portion after the first flipping mechanism 700. The second guide groove 425 guides the two second clamps 422 to be closer to each other in front of the first flipping mechanism 700 to hold the two mold cores 310, and after the fixed mold 320 is assembled and flipped, the distance between the two second clamps 422 is extended to hold the fixed mold 320.

[0045] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 2.

The second injection machine 920 is provided with a second connecting pipe 930. The piston rod of the fourth cylinder 910 is connected to the second connecting pipe 930. The second injection machine 920 injects material into one of the reserved holes 220, and the second biaxial displacement assembly 940 presses the first second movable mold 340 onto the fixed mold 320, so that the first sensing electrode 230 is integrally formed on the measuring tube 210; A second flipping mechanism 1000 is disposed on the right side of the secondary molding mechanism 900. The second flipping mechanism 1000 has the same structure as the first flipping mechanism 700. The second flipping mechanism 1000 is used to flip the two mold cores 310, the fixed mold 320 and the second movable mold 340. A tertiary molding mechanism 1100 is disposed on the right side of the second flipping mechanism 1000. The structure of the tertiary molding mechanism 1100 is consistent with that of the secondary molding mechanism 900. The tertiary molding mechanism 1100 is used to inject material into another reserved hole 220, and then the second second movable mold 340 is pressed against the first second movable mold 340 by the tertiary molding mechanism 1100, so that the second sensing electrode 230 is integrally formed on the measuring tube 210. A material unloading mechanism 1200 is arranged on the right side of the three-stage molding mechanism 1100. The material unloading mechanism 1200 includes a third biaxial displacement assembly 1210 and two fifth cylinders 1220 arranged on the workbench 100. The structure of the third biaxial displacement assembly 1210 is consistent with that of the first biaxial displacement assembly 600. A second vacuum suction cup 1230 is arranged on the piston rod of the fifth cylinder 1220. After the two mold cores 310 are taken out by driving the two second vacuum suction cups 1230 through the two fifth cylinders 1220 , the flow meter 200 is taken out through the third dual-axis displacement assembly 1210 .

[0046] In this embodiment: after the measuring tube 210 is formed, the third cylinder 810 drives the first movable mold 330 to lift, and then the belt conveyor 410 continues to convey the two mold cores 310, the fixed mold 320 and the measuring tube 210 to the right, and pauses when reaching the secondary molding mechanism 900. The fourth cylinder 910 drives the second connecting pipe 930 to align with a reserved hole 220 for injection, and then the second biaxial displacement component 940 grabs a second movable mold 340 from a separate conveying device and covers the fixed mold 320. The second movable mold 340 has the same structure as the fixed mold 320 but has no truncated cone protrusion. Through the molding of the second movable mold 340, a sensing electrode 230 can be formed.

[0047] Then, the fixed mold 320 and the second movable mold 340 are turned over by the second turning mechanism 1000, and the fixed mold 320 is removed by the third molding mechanism 1100, and material is injected into another reserved hole 220, and then another second movable mold 340 is grabbed and covered on the previous second movable mold 340 to mold another sensing electrode 230.

[0048] Finally, the other second movable mold 340 is removed, the two mold cores 310 are extracted through the two fifth cylinders 1220 and the second vacuum suction cups 1230, and then the flow meter 200 is removed through the third dual-axis displacement assembly 1210.
