Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sensor processing, and more particularly to a glue-potting and placement tooling for an intake air temperature and pressure sensor. Background Art
[0002] Pressure sensors are the most widely used type of sensor. Traditional pressure sensors are primarily mechanical devices that use the deformation of an elastic element to indicate pressure. However, these structures are large and heavy, and cannot provide an electrical output. With the advancement of semiconductor technology, semiconductor pressure sensors have emerged. They are characterized by small size, light weight, high accuracy, and excellent temperature characteristics. In particular, with the development of MEMS technology, semiconductor sensors are becoming increasingly miniaturized, offering low power consumption and high reliability. However, during sensor fabrication, they often require glue potting. However, due to the need to secure the sensor to prevent displacement during glue potting, gaps remain between the sensor and the clamping assembly after glue potting, making it difficult for the glue pot to fully encapsulate the sensor, significantly impacting the effectiveness of the glue potting process. Furthermore, since the sensor must be removed from the mounting fixture after glue potting, existing mounting fixtures require external components to assist in removing the glue-potted sensor. This significantly limits the practical use of the mounting fixture and makes it difficult to ensure efficient glue potting. Summary of the Invention
[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a glue potting and placement tool for an intake air temperature and pressure sensor. The technical problem to be solved by the present invention is: currently, when potting glue, since the sensor needs to be fixed to prevent the sensor from shifting, after the glue injection is completed, there is a gap at the contact point between the sensor and the clamping component, making it difficult for the glue to completely wrap the sensor, which greatly affects the glue potting effect of the sensor. At the same time, since the sensor needs to be separated from the placement tool after the glue potting is completed, the existing placement tool needs to use an external structure to assist in disassembling the sensor after the glue potting is completed, which greatly limits the actual use effect of the placement tool and makes it difficult to ensure the glue potting efficiency of the sensor.

[0014] The beneficial effects of the present invention are:
[0015] 1. The present invention provides a second reinforcing head, an air hole, a third conduit and a sealing ring. When the first reinforcing head is separated from the glue pouring processing groove, the third conduit needs to be injected with glue through the glue pouring equipment, so that the glue enters the air hole opened in the second reinforcing head through the third conduit and the sealing ring, and assists the second reinforcing head to be separated from the sensor by liquid squeezing. At this time, the buffer device will gradually shrink as the second reinforcing head moves, and the third conduit will be in a moving state through the telescopic sleeve inside the glue pouring equipment, and at the same time, the cavity left by the removal of the first reinforcing head can be filled, so that the placement tool can fill the missing parts while maintaining the stability of the glue pouring effect on the sensor, avoiding the glue pouring effect being affected by the restrictions of the first and second reinforcing heads, and the heating device can assist the glue in solidifying, thereby ensuring the glue pouring effect of the placement tool on the sensor while ensuring the actual use effect of the placement tool, and the glue pouring of the entire sensor can be achieved through one processing, thereby ensuring the glue pouring efficiency of the placement tool;
[0016] 2. The present invention provides a third control valve, a sealing sleeve, a sealing slide rod and a first reinforcement head. When the third control valve is in a closed state, the air in the sealing sleeve cannot be discharged, and the gas will squeeze the third control valve, causing the sealing slide rod to move downward as the gas pushes it. When the first reinforcement head contacts the sensor as the sealing slide rod pushes it and is fixed to it by the second reinforcement head, the second control valve can be closed, and the fan assembly can be closed at the same time. At this time, the first reinforcement head and the second reinforcement head can achieve the effect of reinforcing the sensor, so that the placement tool can ensure the glue filling effect of the sensor when the sensor is glued, avoid the sensor from being offset due to the ingress of glue during the glue filling process, and ensure the processing quality of the sensor.
[0017] 3. The present invention sets a fan assembly, a first control valve and a second control valve. When the glue injection is completed, the fan assembly is started again, the first control valve and the second control valve are opened, so that the gas is discharged along the sealing sleeve, the sealing slide rod and the air holes opened inside the first reinforcement head, and the first reinforcement head is assisted to separate from the sensor during the glue injection process by gas extrusion. Since the glue is in a solidified state at this time, the glue is not easy to be in a deformed state after the separation is completed. At the same time, the separation effect of the first reinforcement head can be guaranteed by gas extrusion, and the first reinforcement head can be avoided from being difficult to remove due to the adhesion of the solidified glue. In the process of the fan assembly discharging gas, part of the gas will enter the glue processing groove along the sealing cover, and the solidified glue in the glue processing groove can be assisted to separate from the glue processing groove, so that the staff can easily demold the sensor after the glue is filled, and avoid the adhesion of the glue affecting the processing efficiency of the sensor.

The top and bottom ends of the elastic device 13 are both provided with through holes 17. The elastic device 13 is connected to the second control valve 12 and the exhaust pipe 11 respectively through the through holes 17. The bottom end of the elastic device 13 is connected to the top of the first reinforcing head 15. By arranging the second reinforcing head 26, the third conduit 23 and the sealing ring 25, the glue pouring effect is not affected by the restrictions of the first reinforcing head 15 and the second reinforcing head 26, and the heating device 4 can assist the glue in solidifying, thereby ensuring the glue pouring effect of the placement tool on the sensor while ensuring the actual use effect of the placement tool, and the glue pouring of the entire sensor can be achieved through one processing, thereby ensuring the glue pouring efficiency of the placement tool.
[0027] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, the elastic device 13 includes a sealing sleeve 131, the top of the sealing sleeve 131 is connected to the bottom end of the exhaust pipe 11, a sealing slide rod 133 is slidably connected in the sealing sleeve 131, and a return spring 132 is provided in the sealing sleeve 131. The two ends of the return spring 132 are respectively fixedly connected to the upper surface of the inner wall of the sealing sleeve 131 and the top of the sealing slide rod 133. A through hole 17 is provided on the top of the sealing sleeve 131 and the sealing slide rod 133. The sealing sleeve 131 is connected to the exhaust pipe 11 through the through hole 17, and the sealing slide rod 133 is connected to the first reinforcement head 15 through the through hole 17. Because the fan assembly 2 is provided, part of the gas will enter the glue processing groove 20 along the sealing cover 18 during the exhaust process of the fan assembly 2, assisting the glue filling. The solidified glue in the glue processing groove 20 is separated from the glue processing groove 20, so that the staff can easily demould the sensor after glue filling, avoiding the stickiness of the glue and affecting the processing efficiency of the sensor. The outer surface of the sealing sleeve 131 is fixedly connected to the right end of the retaining frame 16, and the other end of the retaining frame 16 is fixedly connected to the outer surface of the connecting pipe 10. The corresponding ends of the opposite surfaces of the two second tees 7 are connected through the circulation pipe 21, and the right end of the third tee 9 is connected to the right side of the sealing cover 18 through the connecting pipe. The inner wall of the sealing cover 18 is fixedly connected to the outer surface of the storage box 19. The upper surface of the storage box 19 is provided with a glue processing groove 20, and the glue processing groove 20 is provided with an air hole 28. The glue processing groove 20 is connected to the sealing cover 18 through the air hole 28.
[0028] like Figure 2 、 Figure 4 、 Figure 5 and Figure 6As shown, the upper surface of the positioning base 1 is fixedly connected to the lower surface of the glue filling device 22, and the left and right side surfaces of the glue filling device 22 are fixedly connected to the opposite surfaces of the two processing tables 30, and the inner walls of the two processing tables 30 are fixedly connected to the outer surfaces of the four storage boxes 19, respectively. Two third conduits 23 are clamped on the left and right side surfaces of the glue filling device 22, and the ends away from the two third conduits 23 are respectively connected to the outer surfaces of the two sealing rings 25. Because the first control valve 8 and the second control valve 12 are provided, when the glue injection is completed, the fan assembly 2 is started again, and the first control valve 8 and the second control valve 12 are opened, so that the gas is discharged along the sealing sleeve 131, the sealing slide rod 133 and the air hole 28 opened inside the first reinforcement head 15, and the gas is squeezed out. The method assists the first reinforcement head 15 to separate from the sensor during the glue injection process. Since the glue is in a solidified state at this time, the first reinforcement head 15 is not easy to be in a deformed state after the separation is completed. At the same time, the gas extrusion method can ensure the separation effect of the first reinforcement head 15, and avoid the first reinforcement head 15 being difficult to remove due to the adhesion of the solidified glue. The lower surface of the sealing ring 25 is fixedly connected to the top of the buffer device 24, and the bottom end of the buffer device 24 is fixedly connected to the upper surface of the positioning base 1. The buffer device 24 includes a telescopic rod 242, and the outer surface of the telescopic rod 242 is sleeved with a buffer spring 241. The two ends of the telescopic rod 242 and the buffer spring 241 are respectively fixedly connected to the upper surface of the positioning base 1 and the lower surface of the sealing ring 25.
[0029] like Figure 2 、 Figure 5 and Figure 6 As shown, the upper surface of the sealing ring 25 is fixedly connected to the lower surface of the second reinforcing head 26, and the third conduit 23 is connected to the second reinforcing head 26 through the sealing ring 25. A mounting hole 29 is provided on the left side of the glue filling device 22, and the first conduit 3 is located in the mounting hole 29. The top of the first reinforcing head 15 and the second reinforcing head 26 are both provided with air holes 28. Due to the provision of the first reinforcing head 15 and the second reinforcing head 26, the placement tooling can ensure the glue filling effect of the sensor when the sensor is glued, avoiding the sensor from being offset due to the entry of glue during the glue filling process, thereby ensuring the processing quality of the sensor. Limiting slots 27 are provided on the opposite surfaces of the first reinforcing head 15 and the second reinforcing head 26. The shape of the limiting slots 27 is adapted to the pressure sensor. The outer surface of the exhaust pipe 11 is provided with a second control valve 12. The left side of the glue filling device 22 is fixedly connected to the right side of the heating device 4.
[0030] Working principle of the present invention: When using the placement tool, the sensor to be glued is placed above the second reinforcement head 26 in the glue processing groove 20, and is initially fixed to the pressure sensor through the limit slot 27 above the second reinforcement head 26. After the fixation is completed, the fan assembly 2 is started. When the fan assembly 2 is running, the outside air will enter the sealing sleeve 131 along the first conduit 3, the heating device 4, the second conduit 6 and the exhaust pipe 11, increasing the internal air pressure of the sealing sleeve 131. At this time, the third control is closed. Valve 14, when the third control valve 14 is in a closed state, the air in the sealing sleeve 131 cannot be discharged, and the gas will squeeze the third control valve 14, causing the sealing slide 133 to move downward as the gas pushes it. When the first reinforcement head 15 contacts the sensor as the sealing slide 133 pushes it and is fixed to it by the second reinforcement head 26, the second control valve 12 can be closed, and the fan assembly 2 can be closed at the same time. At this time, the first reinforcement head 15 and the second reinforcement head 26 can achieve the effect of reinforcing the sensor. When the injection is completed After that, the fan assembly 2 is started again, and the first control valve 8 and the second control valve 12 are opened, so that the gas is discharged along the sealing sleeve 131, the sealing slide rod 133 and the air hole 28 opened inside the first reinforcement head 15, and the first reinforcement head 15 is assisted to separate from the sensor during the glue injection process by gas extrusion. As part of the gas discharged by the fan assembly 2 enters the glue processing groove 20 along the sealing cover 18, the glue solidified in the glue processing groove 20 is assisted to separate from the glue processing groove 20. When the first reinforcement head 15 is separated from the sensor, the gas is discharged from the sealing cover 18. After the glue processing groove 20 is filled, the third tube 23 needs to be injected with glue through the glue filling equipment 22, so that the glue passes through the third tube 23 and the sealing ring 25 into the air hole 28 opened inside the second reinforcement head 26, and the second reinforcement head 26 is assisted to separate from the sensor by liquid squeezing. At this time, the buffer device 24 will gradually shrink with the movement of the second reinforcement head 26, and the third tube 23 will be in a moving state through the telescopic sleeve inside the glue filling equipment 22, and at the same time, it can fill the hole after the first reinforcement head 15 is removed.
