Description

Technical Field

[0001] The invention relates to the technical field of semiconductor parts processing, in particular to a semiconductor flow switch sensor assembly magnetic reed switch tool. Background Art

[0002] Semiconductor sensor is a new type of semiconductor device, whose main function is to convert non-electrical signals into electrical signals. Semiconductor sensor can realize the mutual conversion between physical quantities such as electricity, light, temperature, displacement, pressure, etc., and is easy to realize integration and multifunctionality. It is widely used in automated detection systems. In the production process of semiconductor sensors, the assembly link is particularly related to the quality of the final product. The flow switch sensor (Flow Switch Sensor) in its semiconductor sensor is a device used to monitor the flow of liquid, air or other gaseous media through a pipeline, system or loop, and is composed of a flow sensitive element and a switch control device. The specific steps for installing the reed switch to the flow switch sensor in the existing production process are as follows:

[0003] 1. Insert: Insert the reed switch into the mounting hole of the flow switch sensor;

[0004] 2. Adjust the position: manually adjust the coaxiality and axial position of the mounting hole of the flow switch sensor and the reed switch, and the gap between the mounting hole of the flow switch sensor and the outer circumference of the reed switch should be kept within 1mm;

[0005] 3. Glue filling: drip glue into the gap between the mounting hole of the switch sensor and the outer circumference of the reed switch;

[0006] 4. Maintain: Maintain the relative position of the switch sensor mounting hole and the reed switch until the glue dries and solidifies.

[0007] However, the adjustment and maintenance status in the above installation process are all achieved manually, so the coaxiality of the adjustment will be poor in the entire assembly process, and the stability in the relative state maintenance will be poor. The reed switch potting will be skewed, resulting in the flow switch sensor tripping point error being different from the set value. At the same time, during the glue pouring process, the reed switch is affected by the buoyancy of the liquid glue, causing the reed switch to shift, which will also cause the flow switch sensor tripping point error being different from the set value, resulting in inaccurate position adjustment, resulting in the reed switch being unable to adjust the switch of the flow switch sensor, which not only affects the efficiency of semiconductor sensor manufacturing, but also greatly affects the reliability of the final product quality.

[0008] Therefore, how to improve the stability and accuracy of the mounting hole assembly of the reed switch and the flow switch sensor is a technical problem that technicians in this field currently need to solve. Summary of the invention

[0044] The core of the present invention is to provide a semiconductor flow switch sensor assembly reed switch tooling for improving the stability and accuracy of the assembly of the mounting hole of the reed switch and the flow switch sensor.

[0045] like Figure 1As shown, an embodiment of the present invention discloses a semiconductor flow switch sensor assembly reed switch tooling, through which the semiconductor flow switch sensor assembly reed switch tooling provided by the embodiment of the present invention is used to assemble the reed switch 20 into the mounting hole of the flow switch sensor 10, including a fixing portion 100, a clamping portion 200 and an adjusting portion 300. Among them, the fixing part 100 is provided with a clamping shell 110, which is clamped to the outer shell of the flow switch sensor 10 through the clamping shell 110, so that the semiconductor flow switch sensor assembly reed switch tooling provided in this embodiment is stably fixed on the flow switch sensor 10, and the reed switch 20 is clamped and fixed by the clamping claws of the clamping part 200, so that the reed switch 20 can always maintain good stability during the entire assembly process, and avoid large displacement and shaking of the reed switch 20 during the assembly process. In addition, the positioning mechanism of the clamping part 200 can make the reed switch 20 located on the axis of the mounting hole, ensuring that the reed switch 20 and the mounting hole have good coaxiality, so that the reed switch 20 and the inner wall of the mounting hole maintain a uniform gap, thereby improving the uniformity of the glue injection and the accuracy of the position of the reed switch 20. At the same time, the semiconductor flow switch sensor assembly reed switch tool provided in this embodiment is also provided with an adjustment part 300 having an adjustment knob 310 and a driving mechanism. The adjustment knob 310 is connected to the clamping part 200 through the driving mechanism. When the adjustment knob 310 is turned, the clamping part 200 is driven by the driving mechanism to move along the axial direction of the mounting hole, thereby adjusting the depth of the reed switch 20 fastened to the clamping part 200 extending into the mounting hole, so as to ensure that the insertion depth of the reed switch 20 can meet the assembly requirements. Therefore, in the entire assembly process of the reed switch 20 and the mounting hole of the flow switch sensor 10, the semiconductor flow switch sensor assembly reed switch tool provided in this embodiment realizes that the reed switch 20 has a high precision position in the mounting hole, ensures the normal operation of the reed switch 20 adjusting the switch of the flow switch sensor 10, and improves the quality and qualified rate of product manufacturing.

[0046] like Figure 2 and Figure 3As shown, the clamping part 200 also includes a clamping base 210 and a compression spring 220, and the clamping includes a first clamping 230 and a second clamping 240. The clamping base 210 is also provided with a sliding shaft 211, and the first clamping 230 and the second clamping 240 are both connected to the sliding shaft 211, and at least one of the first clamping 230 and the second clamping 240 is slidably mounted on the sliding shaft 211, and the compression spring 220 is sleeved on the sliding shaft 211, and one end of the compression spring 220 abuts on the clamping base 210, and the other end of the compression spring 220 abuts on the slidable one of the first clamping 230 and the second clamping 240, so that the first clamping 230 and the second clamping 240 are pressed against each other by the elastic force of the compression spring 220, so as to clamp and fix the magnetic reed switch 20. In a specific embodiment, the first clamp 230 and the second clamp 240 can be slidably connected to the sliding shaft 211, so that the first clamp 230 and the second clamp 240 can move closer or farther, and the first clamp 230 and the second clamp 240 are respectively arranged with a compression spring 220, and the two compression springs 220 provide elastic pressure at the same time, further improving the clamping force of the first clamp 230 and the second clamp 240, and improving the stability of the clamping claws clamping the reed switch 20.

[0047] In addition, the clamping portion 200 is also provided with a guide block 250, which is fixedly connected to the clamping base 210, and the guide block 250 is provided with a guide hole 251, and the first clamping claw 230 and the second clamping claw 240 extend through the guide hole 251 toward the mounting hole of the flow switch sensor 10, and the guide hole 251 extends along the sliding direction of the first clamping claw 230 and the second clamping claw 240, so that during the sliding process of the first clamping claw 230 and the second clamping claw 240, the guide hole 251 plays a guiding role, ensuring that the sliding of the first clamping claw 230 and the second clamping claw 240 has good stability and smoothness, which is conducive to improving the efficiency of the first clamping claw 230 and the second clamping claw 240 clamping and fixing the reed switch 20, as well as the separate disassembly work. In a specific embodiment, a key slot is provided in the clamp base 210, and a key block is provided in the first clamp 230 and the second clamp 240. The first clamp 230 and the second clamp 240 are respectively slidably installed in the key slot through the key block. The key slot extends along the moving direction of the first clamp 230 and the second clamp 240, so that the first clamp 230 and the second clamp 240 slide along the key slot to clamp or separate each other. In addition, during the process of pressing and separating the first clamp 230 and the second clamp 240, the key block cooperates with the key slot to avoid the problem of unstable depth of the reed switch 20 inserted into the installation hole when the first clamp 230 and the second clamp 240 rotate around the sliding shaft 211, further improving the stability of the clamping of the reed switch 20. Alternatively, a long square hole is provided in the clamp base 210, and the first clamp 230 and the second clamp 240 are square rods that match the square hole. The square rods are slidably installed in the square hole, which can also achieve the above effect.

[0048] like Figure 3 As shown, the positioning mechanism is configured as a clamping ring 260 clamped on the cylindrical surface of the reed switch 20, a portion of the clamping ring 260 is located on the first clamping claw 230, and the other portion of the clamping ring is arranged on the second clamping claw 240, and when the semiconductor flow switch sensor assembly reed switch tooling provided in this embodiment is fixed to the flow switch sensor 10 through the fixing portion 100, the center of the clamping ring 260 is located on the axis of the mounting hole, so that when the reed switch 20 is clamped and fixed by the clamping ring 260, the reed switch 20 is on the axis of the mounting hole, achieving good coaxiality between the reed switch 20 and the mounting hole.

[0049] like Figure 1As shown, a clamping inlet is provided on one side of the clamping shell 110, so that when the semiconductor flow switch sensor assembly magnetic reed switch tool provided in this embodiment is installed with the flow switch sensor 10, the clamping shell 110 is inserted into the outer shell of the flow switch sensor 10 through the clamping inlet, so that the clamping shell 110 is clamped on the flow switch sensor 10. A through hole is provided at one end of the clamping shell 110 that fits the mounting hole of the flow switch sensor 10, and the magnetic reed switch 20 extends into the mounting hole of the flow switch sensor 10 through the through hole.

[0050] like Figure 4 and Figure 5 As shown, in another specific embodiment, the clamping shell 110 is provided with a through hole and a button 120 is provided, and a lower card plate 130 is provided at the end corresponding to the through hole. The button 120 is connected to the lower card plate 130 through a push rod 121, and the push rod 121 is also sleeved with a tension spring 140, and the tension spring 140 is connected to the lower card plate 130, so that pressing the button 120 pushes the lower card plate 130 to move and insert the clamping shell 110 into the flow switch sensor 10. When the lower card plate 130 is attached to the outer shell of the flow switch sensor 10, the stretched tension spring 140 undergoes elastic deformation, and the tension spring 140 applies elastic tension to the lower card plate 130, so that the lower card plate 130 is pressed tightly against the outer shell of the flow switch sensor 10, thereby referring to Figure 1 The clamping shell 110 is clamped and fixed to the outer shell of the flow switch sensor 10 by means of the tension spring 140 and the lower clamping plate 130, thereby ensuring the stability of the clamping connection between the clamping shell 110 and the flow switch sensor 10 and preventing the reed switch 20 from deviating and shaking in the mounting hole of the flow switch sensor 10 during the assembly process.

[0051] At the same time, in the process of pouring glue into the gap between the reed switch 20 and the mounting hole of the switch sensor, in order to prevent a large amount of glue in the mounting hole from leaking out from the lower card plate 130, the lower card plate 130 provided in this embodiment is provided with a storage groove 131 on the side facing the mounting hole, and excess glue can be stored through the storage groove 131. In addition, a sealing gasket 132 is also laid on the side facing the mounting hole of the lower card plate 130, and the sealing gasket 132 surrounds the periphery of the storage groove 131. Therefore, the storage groove 131 and the sealing gasket 132 prevent the glue from leaking out, thereby ensuring the reliability of the bonding and fixation of the reed switch 20.

[0052] like Figure 6 and Figure 7As shown, the button 120 is also provided with a conical push block 122, and the conical push block 122 is located between the first clamping claw 230 and the second clamping claw 240. Therefore, when the push button 120 is pushed, the conical push block 122 connected to the push button 120 moves toward the gap between the first clamping claw 230 and the second clamping claw 240. As the conical push block 122 continues to move downward, the first clamping claw 230 and the second clamping claw 240 are pushed apart, thereby facilitating the placement of the reed switch 20 in the clamping ring 260, or facilitating the quick removal of the reed switch 20 from the clamping ring 260, thereby improving the efficiency of tooling installation and use.

[0053] like Figure 4 and Figure 5 As shown, the driving mechanism includes an adjusting screw 320 and a nut 330 that cooperate with each other through threads. The nut 330 is fixedly connected to the clamping shell 110. One end of the adjusting screw 320 extends along the axial direction of the mounting hole and is connected to the clamping base 210. The other end of the adjusting screw 320 is connected to the adjusting knob 310. By rotating the adjusting knob 310, the adjusting screw 320 that cooperates with the nut 330 can move up and down along the axial direction of the mounting hole, driving the clamping base 210 connected to the adjusting screw 320 to move, thereby completing the driving of the driving mechanism.

[0054] like Figure 3 As shown, the adjustment part also includes a guide rail 340, and the guide rail 340 is provided with a guide rail groove 341, which extends along the axial direction of the adjusting screw 320, and a slider 212 is arranged on the clamping base 210, and the slider 212 is slidably installed in the guide rail groove 341, and at the same time, the slider 212 is extended along the extension direction of the guide rail groove 341 and connected to the guide block 250, so that the guide block 250 is connected to the clamping base 210 through the slider 212, so that the guide rail groove 341 of the guide rail 340 cooperates with the slider 212 of the clamping base 210, so that the guide rail groove 341 guides the slider 212, thereby ensuring that the adjusting knob 310 drives the clamping base 210 through the driving mechanism to smoothly and steadily move up and down along the axial direction of the mounting hole of the flow switch sensor 10.

[0055] Furthermore, during the installation and use of the semiconductor flow switch sensor assembly reed switch tooling and the flow switch sensor 10 provided in the present embodiment, when the staff presses the button 120 with one hand and holds the clamping shell 110 with the other hand, the hand may accidentally touch the adjusting knob 310 or the adjusting screw 320 to move the clamping base 210, or the clamping base 210 may be forced to move downward during the pressing process, which will cause the insertion depth of the reed switch 20 clamped in the clamping ring 260 into the mounting hole of the flow switch sensor 10 to change, resulting in the problem of not meeting the assembly requirements. To this end, the adjustment part 300 in the magnetic reed switch tooling of the semiconductor flow switch sensor provided in this embodiment is also provided with a locking rod 350, one end of the locking rod 350 is connected to the button 120, and the other end of the locking rod 350 is provided with a locking section 351, and the adjusting knob 310 is provided with a locking gear 311, so that while the lower clamping plate 130 is pushed to move by the adjusting knob 310, the adjusting knob 310 also pushes the locking rod 350 to move, so that the locking section 351 at one end of the locking rod 350 extends into the tooth groove of the locking gear 311, thereby locking the locking gear 311, preventing the adjustment screw 320 connected to the adjusting knob 310 from rotating, ensuring the stability of the insertion depth of the magnetic reed switch 20 fixed in the clamping ring 260, and improving the accuracy of the position of the magnetic reed switch 20 in the mounting hole of the flow switch sensor 10.

[0056] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0057] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
