Description

Technical Field

[0001] The utility model relates to the technical field of sensor manufacturing, in particular to vertical welding equipment. Background Art

[0002] Pressure transmitter is a device that converts pressure into pneumatic or electric signals for control and remote transmission. It can convert physical pressure parameters such as gas and liquid sensed by the pressure measuring element sensor into standard electrical signals to supply secondary instruments such as indicator alarms, recorders, and regulators for measurement, indication, and process regulation. Pressure transmitters are widely used in the pharmaceutical, food, and industrial manufacturing industries. Submersible level gauges are used to measure the depth of various media and feed back to the terminal, so as to control the depth of the media or perform other operations.

[0003] The core component of the sensor in the capacitive pressure transmitter is the sensitive element. The concentricity of the guard ring and the curved seat after welding in the sensitive element plays a vital role in the performance of the entire pressure transmitter. Therefore, during the welding process of the sensitive element, it is very critical to ensure that its concentricity is within the specified range.

[0004] The coaxiality of the two protective rings after the sensitive element is welded is the main reason affecting the performance of the entire transmitter. However, due to the high concentricity requirements of the protective rings after welding, the concentricity after welding is required to be within 0.1mm. However, most of the existing equipment is horizontally designed, that is, the components of the sensitive element are placed horizontally for welding. This placement method will be affected by gravity and misaligned, which will lead to the failure to meet the higher concentricity requirements, thus affecting the performance of the pressure transmitter.

[0005] Therefore, how to solve the problem of concentricity deviation of the protective ring and curved seat of the sensor due to the influence of gravity during the welding process needs to be solved urgently. Utility Model Content

[0054] See also Figures 1 to 6In some embodiments of the utility model, a vertical welding device 1 is used for welding a sensor 2, wherein the sensor 2 includes a main body 21 and a first ring 22 and a second ring 23 respectively arranged at two axial ends of the main body 21, and the vertical welding device 1 includes: a frame 10; a holding mechanism 11, mounted on the frame 10, and used to keep the first ring 22, the main body 21, and the second ring 23 of the sensor 2 aligned and concentric in the axial direction of the main body 21, and the axial direction of the main body 21 is perpendicular to the horizontal plane; a pressing mechanism 12, mounted on the frame 1 0, used to press the first ring 22, the main body 21 and the second ring 23 of the sensor 2 in the axial direction of the main body 21; the rotating mechanism 13, which is installed on the frame 10 and can rotate relative to the frame 10 in the horizontal plane; the welding mechanism 14, which is installed on the rotating mechanism 13, and the rotating mechanism 13 can rotate to drive the welding mechanism 14 to rotate around the circumference of the sensor 2, and weld the first ring 22, the main body 21 and the second ring 23 of the sensor 2 into one, and the circumference of the sensor 2 is located in the horizontal plane.

[0055] For details, see Figure 2 as well as Figures 4 to 6 First, the alignment mechanism 11 installed on the frame 10 ensures the center alignment of the first ring 22, the main body 21 and the second ring 23 that constitute the sensor 2 stacked in the vertical direction, so that the three parts of the sensor 2 have a higher concentricity, which is convenient for subsequent welding and obtaining a sensor 2 with high precision and high concentricity; then, after the alignment mechanism 11 completes the concentricity positioning and alignment of the three parts of the above-mentioned sensor 2, the clamping mechanism 12 located in the vertical direction and above the sensor 2 clamps and fixes the three parts of the sensor 2 to facilitate subsequent welding; wherein, the welding mechanism 14 installed on the rotating mechanism 13 can be driven by the rotating mechanism 13 to surround the circumferential outer side of the sensor 2 to weld the outer peripheral surface of the sensor 2.

[0056] It is understandable that the above-mentioned clamping mechanism 11 can release the three parts of the sensor 2 after the clamping mechanism 12 clamps the three parts, so as to make way for the welding mechanism 14 to perform welding operations.

[0057] In the prior art, the welding method for the sensor 2 composed of the first ring 22, the main body 21 and the second ring 23 is a horizontal design: the three parts are placed in the horizontal direction, and the axial direction of the sensor 2 is the same as the horizontal direction. During the welding process, due to the influence of gravity, the three parts may be misaligned, resulting in poor concentricity. It is worth noting that an innovative point of the welding device for welding sensors provided by the utility model is that the device is a vertical design, that is, the first ring 22, the main body 21 and the second ring 23 of the sensor 2 to be welded are stacked in the vertical direction in sequence, the "vertical direction" described in this specification is the "direction of gravity", and the axial direction of the sensor 2 is the same as the vertical direction and the direction of gravity, and then the clamping mechanism 12 that can move in the vertical direction is used to clamp the above three parts along the axial direction of the sensor 2, so that the three parts will not be misaligned with each other due to the influence of gravity during the subsequent welding process, thereby causing the problem of poor concentricity between the three parts.

[0058] See also Figure 6 In some embodiments of the utility model, the vertical welding device 1 is used to weld a sensor 2, and the sensor 2 includes a pressure sensor that can measure the pressure of liquid or gas; wherein the pressure sensor also includes an isolation diaphragm 24 and a center diaphragm 25.

[0060] For details, see Figure 4The first fixed portion 111 of the first cylinder is installed on the frame 10, and the first movable portion 112 of the first cylinder can move relative to the first fixed portion 111 and the frame 10, so as to approach, abut and push at least one of the first ring 22, the main body 21 and the second ring 23, so that these three parts can be kept aligned and concentric in the axial direction of the sensor 2; then the clamping mechanism 12 presses down in the vertical direction and clamps and fixes the three parts to facilitate subsequent welding. At this time, the first movable portion 112 of the first cylinder can move away from and release the three parts of the sensor 2 to make way for the welding mechanism 14 to facilitate the welding operation.

[0061] See also Figure 4 In some embodiments of the present invention, the first movable portion 112 of the first cylinder can move closer to or farther away from the sensor 2 along the radial direction of the sensor 2. It can be understood that the design is simple and efficient, and can reliably ensure the alignment effect of the alignment mechanism 11 on the three parts of the sensor 2, so that the sensor 2 obtained by the final processing has a sufficiently high concentricity.

[0062] See also Figure 4 In some embodiments of the present invention, the number of the alignment mechanisms 11 is at least two, which are suitable for being distributed along the circumference of the sensor 2. Of course, in other embodiments, a larger number of alignment mechanisms 11 can be selected according to actual needs and design standards to ensure that the three parts of the sensor 2 have a sufficiently high concentricity.

[0063] See also Figure 4 In some embodiments of the utility model, the alignment mechanism 11 includes a profiling member 113 mounted on the first movable portion 112 of the first cylinder; the profiling member 113 has a profiling surface at one end thereof for contacting the circumferential outer surface of the sensor 2, and the shape of the profiling surface is adapted to be similar to the shape of the circumferential outer surface of the sensor 2. It is worth noting that the profiling member 113 with a profiling surface design can achieve the purpose of "using only two alignment mechanisms 11 to achieve concentric alignment of three parts of the sensor 2".

[0064] See also Figure 2In some embodiments of the utility model, the pressing mechanism 12 includes a second cylinder mounted on the frame 10; the second cylinder includes a second fixed portion 121 mounted on the frame 10 and a second movable portion 122 movable relative to the second fixed portion 121; the second movable portion 122 can move relative to the frame 10 to abut against the first ring 22, thereby sequentially pressing the first ring 22, the main body 21 and the second ring 23 along the axial direction of the sensor 2, and the second movable portion 122 can be away from the sensor 2 after the first ring 22, the main body 21 and the second ring 23 of the sensor 2 are welded. It can be understood that the specific specifications and parameters of the second cylinder can be selected and adjusted according to actual application requirements.

[0065] See also Figure 5 In some embodiments of the present invention, the rotating mechanism 13 includes: a rotating drive member 131, which is movably connected to the frame 10 and can rotate relative to the frame 10; a turntable 132, which is connected to the rotating drive member 131 and can be driven by the rotating drive member 131 to rotate relative to the frame 10. For details, see Figure 5 The rotating driving member 131 drives the turntable 132 to rotate on a horizontal plane perpendicular to the vertical direction, thereby driving the welding mechanism 14 installed on the turntable 132 to surround the outer periphery of the sensor 2 to weld the sensor 2.

[0066] In some embodiments of the present invention, the rotating driving member 131 may be a motor, and the specific specifications and parameters of the motor may be selected and adjusted according to actual conditions.

The above design enables the welding mechanism 14 installed on the turntable 132 to surround the outer periphery of the sensor 2 and weld the sensor 2.

[0068] See also Figure 4In some embodiments of the present invention, the welding mechanism 14 includes: a welding driver 141 connected to the rotating mechanism 13; a welding gun 142 connected to the welding driver 141; wherein the welding driver 141 is used to drive the welding gun 142 to approach the sensor 2 to weld the first ring 22, the main body 21 and the second ring 23 of the sensor 2 into one body, and is also used to drive the welding gun 142 away from the sensor 2 after welding. It can be understood that when welding needs to be performed, the welding driver 141 drives the welding gun 142 to approach the sensor 2, and after welding is completed, the welding driver 141 can drive the welding gun 142 away from the sensor 2, thereby avoiding the scratching problem that may occur when the sensor 2 is removed later.

[0069] In some embodiments of the present invention, multiple sets of welding mechanisms 14 or multiple welding guns 142 may be provided to weld the sensor 2 at the same time, thereby improving processing efficiency.

[0070] In some embodiments of the present invention, the welding gun 142 may specifically be a argon arc welding machine.

[0071] In some embodiments of the present invention, the welding driving component 141 may be a motor or a cylinder, and the motor or cylinder with specific specifications and parameters may be selected and adjusted according to actual conditions.

[0072] See also Figure 4 In some embodiments of the present invention, the welding driver 141 is used to drive the welding gun 142 to move closer to or farther from the sensor 2 along the radial direction of the sensor 2. It can be understood that the above design enables the muzzle of the welding gun 142 to face the sensor 2, which is convenient for welding. Of course, in other embodiments of the present invention, the muzzle of the welding gun 142 can also be set to "diagonally face the outer peripheral surface of the sensor 2".

It can be understood that the function of the profiling wheel 143 is to ensure the distance between the welding gun 142 and the outer circumference of the sensor 2, so as to ensure that a high welding quality can be obtained for sensors 2 with different specific structures and forms.

[0074] In some embodiments of the present invention, the welding mechanism 14 further includes: a camera assembly, which is arranged beside the welding gun 142 and is used to monitor the distance between the muzzle of the welding gun 142 and the sensor 2, so that the staff can observe the welding process in time and at any time.

[0075] In some embodiments of the present invention, the welding driver 141 is configured as a three-axis mobile type, that is, the welding driver 141 can drive the welding gun 142 to translate along the X-axis, Y-axis, and Z-axis that are perpendicular to each other, wherein the Z-axis can be the same as the vertical direction and the gravity direction, and the horizontal plane is composed of the X-axis and the Y-axis. The above design can ensure that a higher welding quality can be obtained for sensors 2 with different specific structures and shapes.
