Description

Technical Field

[0001] This application relates to the technical field of temperature sensor manufacturing, and in particular to a temperature sensor protective sleeve positioning fixture and a base adhesive filling device. Background Technology

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. Temperature sensors are the core component of temperature measuring instruments, and there are many different types. Based on the measurement method, they can be divided into two main categories: contact and non-contact sensors. Based on the characteristics of the sensor materials and electronic components, they can be divided into two categories: resistance temperature detectors (RTDs) and thermocouples.

[0003] In the case of non-contact temperature sensors, the thermistor is encased in a protective sleeve. During manufacturing, a base coat is first applied inside the protective sleeve, then the thermistor is placed inside the sleeve, and finally, the sleeve is sealed with adhesive.

[0004] In order to meet the needs of large-scale production, it is urgent to develop a filling equipment for applying base adhesive to temperature sensor protective covers. Utility Model Content

[0005] The purpose of this application is to provide a temperature sensor protective sleeve positioning fixture and a base adhesive filling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides a temperature sensor protective sleeve positioning fixture and a base adhesive filling device, which adopts the following technical solution.

[0007] On the one hand, this application provides a positioning clamp for a temperature sensor protective sleeve, which adopts the following technical solution:

[0008] A temperature sensor protective sleeve positioning fixture includes a base, a storage plate, and a pressure plate. Support blocks are symmetrically fixed to both sides of the top of the base, and screws are symmetrically fixed to both sides of the top of each support block. The storage plate has a plurality of positioning holes evenly distributed on its surface. The pressure plate has a plurality of through holes corresponding to the positions of the positioning holes, and a recessed hole is formed at the bottom of each through hole corresponding to the position of the positioning hole. The diameter of the recessed hole is larger than the diameter of the through hole. Connection holes are formed on both the pressure plate and the storage plate corresponding to the positions of the screws. A wing nut is screwed onto the screw. The bottom of the storage plate is in contact with the surface of the support blocks.

[0009] The support block has ear blocks symmetrically arranged on both sides.

[0010] On the other hand, this application also provides a base adhesive filling device using the above-mentioned temperature sensor protective sleeve positioning clamp, specifically adopting the following technical solution:

[0011] A base adhesive filling device includes a frame, in which a dispensing machine is installed. A placement frame for fixing the base is provided in the frame corresponding to the bottom of the dispensing machine. A clearance groove is provided in the middle of the placement frame, and positioning grooves are provided on both sides of the placement frame corresponding to the position of the ear block. Quick clamps are also symmetrically fixed on both sides of the surface of the placement frame.

[0012] Preferably, the frame is further provided with a flip motor, a reducer and a drive gear. The placement rack is rotatably disposed in the frame. An external gear ring is fixed on one side of the placement rack. The flip motor and the reducer are both installed in the frame. The drive gear is connected to the reducer and meshes with the external gear ring. A dust blowing mechanism is provided at the bottom of the placement rack.

[0013] The dust blowing mechanism includes an electric lifting rod and a wind box. The electric lifting rod is vertically fixed inside the frame. The wind box is located on the top of the electric lifting rod. Several air outlet needle tubes are evenly installed on the top surface of the wind box. The air outlet needle tubes can correspond one-to-one with the positioning holes on the storage plate.

[0014] By adopting the above technical solution, the air outlet needle is inserted into the inner wall of the temperature sensor protective sleeve to blow dust off the inner wall of the temperature sensor protective sleeve, thereby improving the adhesion between the base adhesive and the temperature sensor protective sleeve, and thus improving the quality of the temperature sensor.

[0015] Preferably, in order to remove dust in a timely manner, a dust suction hood is provided on the side of the dust blowing mechanism inside the frame, and a vacuum cleaner is connected to the outside of the dust suction hood.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. This temperature sensor protective sleeve positioning fixture can clamp a large number of temperature sensor protective sleeves at once. The clamping is relatively simple, and in the subsequent wiring process, the pressure plate can be removed and the temperature sensor protective sleeves can still be neatly stored in the storage plate, which can continue to assist the staff in wiring.

[0018] 2. The base adhesive filling equipment uses the aforementioned temperature sensor protective sleeve positioning fixture, which can process multiple temperature sensor protective sleeves at one time. The equipment is also equipped with a dust blowing mechanism, which can remove debris from the inner wall of the temperature sensor protective sleeve, thereby improving the adhesion between the base adhesive and the temperature sensor protective sleeve. This not only improves product quality but also increases production efficiency. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a positioning fixture for a temperature sensor protective sleeve, referring to... Figure 1-3 The device includes a base 1, a storage plate 2, and a pressure plate 3. Support blocks 11 are symmetrically fixed on both sides of the top of the base 1. Screws 12 are symmetrically fixed on both sides of the top of the support blocks 11. Several positioning holes 21 are evenly opened on the surface of the storage plate 2. Several through holes 31 are opened on the pressure plate 3 corresponding to the positions of the positioning holes 21. A groove hole 311 is opened at the bottom of the through hole 31 corresponding to the position of the positioning hole 21. The diameter of the groove hole 311 is larger than the diameter of the through hole 31. Connection holes are opened on both the pressure plate 3 and the storage plate 2 corresponding to the positions of the screws 12. A wing nut 4 is screwed onto the screw 12. The bottom of the storage plate 2 is in contact with the surface of the support blocks 11. Ear blocks 111 are symmetrically arranged on both sides of the support blocks 11.

[0027] The implementation principle of the temperature sensor protective sleeve positioning clamp in this application embodiment is as follows:

[0028] In use, the storage plate 2 is first placed flat on the support block 11. The operator places a temperature sensor protective sleeve in each positioning hole 21. The bottom end of the temperature sensor protective sleeve can contact the surface of the base 1. Then, the operator can use another plate-shaped tool to flatten all the temperature sensor protective sleeves. Then, the pressure plate 3 is placed on the top of the storage plate 2 along the screw 12. At this time, the top end of the temperature sensor protective sleeve can abut against the slot hole 311, so that all the temperature sensor protective sleeves can be pressed and positioned. A large number of temperature sensor protective sleeves can be loaded at one time.

[0029] This application also discloses a base adhesive filling device using the above-mentioned temperature sensor protective sleeve positioning fixture, referring to... Figure 4-5 The system includes a frame 5, a dispensing machine 6 installed inside the frame 5, a mounting bracket 7 for fixing the base 1 is provided at the bottom of the dispensing machine 6 inside the frame 5, a clearance groove 71 is provided in the middle of the mounting bracket 7, and positioning grooves 711 are provided on both sides of the mounting bracket 7 corresponding to the positions of the ear blocks 111. Quick clamps 8 are also symmetrically fixed on both sides of the surface of the mounting bracket 7.

[0030] Reference Figure 4 The frame 5 is also equipped with a flip motor 51, a reducer and a drive gear 52. The placement rack 7 is rotatably installed in the frame 5. An external gear ring is fixed on one side of the placement rack 7. The flip motor 51 and the reducer are both installed in the frame 5. The drive gear 52 is connected to the reducer and meshes with the external gear ring. A dust blowing mechanism 9 is provided at the bottom of the placement rack 7.

[0031] The dust blowing mechanism 9 includes an electric lifting rod 91 and a wind box 92. The electric lifting rod 91 is vertically fixed inside the frame 5. The wind box 92 is set on the top of the electric lifting rod 91. Several air outlet needle tubes 93 are evenly installed on the top surface of the wind box 92. The air outlet needle tubes 93 can correspond one-to-one with the positioning holes 21 on the storage plate 2. In order to ensure that the wind box 92 can move vertically up and down, guide rods 94 are fixed at the four corners of the bottom of the wind box 92.

[0032] In order to quickly remove pollutants, a dust suction hood 10 is provided on the side of the dust blowing mechanism 9 inside the frame 5, and a vacuum cleaner is connected to the outside of the dust suction hood 10.

[0033] The implementation principle of a primer filling device according to an embodiment of this application is as follows:

[0034] During the adhesive application process, the worker places the ear block 111 on the base 1 into the positioning groove 711, and then uses the quick clamps 8 on both sides to press the base 1 firmly onto the placement frame 7. The flip motor 51 drives the placement frame 7 to rotate via the drive gear 52, causing the positioning fixture to flip downwards. The electric lifting rod 91 in the dust blowing mechanism 9 pushes the air box 92 upwards, and the air outlet needle tube 93 on the surface of the air box 92 enters the temperature sensor protective sleeve to remove dust from the inner wall of the temperature sensor protective sleeve. This removes impurities and improves the adhesion between the base adhesive and the temperature sensor protective sleeve. After the dust removal is completed, the flip motor 51 drives the positioning fixture to return to its original position. At this time, the dispensing machine 6 dispenses adhesive one by one according to the set program, which can produce multiple units at once, greatly improving production efficiency.

[0035] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
