Description

Technical Field

[0001] This utility model relates to the field of sensor adhesive coating technology, and more specifically, to a small-structure sensor adhesive coating and fixing device. Background Technology

[0002] MEMS sensors are characterized by miniaturization, intelligence, integration, systematization, and multifunctionality, and are widely used in various fields such as aerospace, automotive, industry, and agriculture. As component structures become increasingly smaller and precision requirements become higher, there are also higher demands on their assembly accuracy and operation methods.

[0003] Furthermore, during the sensor production process, a gluing machine is needed to apply adhesive for encapsulation. Existing gluing machines typically place the sensor on the machine's mounting table, and then the automated machine applies adhesive. However, because the sensor is not fixed in place during gluing, it may shift slightly, affecting the accuracy of the adhesive application and consequently impacting the encapsulation efficiency. If the sensor components are small, manual adjustments are required to ensure coaxiality before 360° manual gluing. This method is not only costly, difficult, and inefficient, but also results in low accuracy, poor coaxiality, and low consistency, leading to overall low gluing efficiency for the capacitor. Utility Model Content

[0004] The purpose of this invention is to provide a small-structure sensor adhesive fixing device, which addresses the shortcomings of existing technologies and solves the problems mentioned in the background.

[0005] The technical solution of this utility model is implemented as follows:

[0006] The utility model provides a small structure sensor adhesive fixing device, including a base, a placement block for placing the sensor is installed on the side wall of the base, and a placement opening adapted to the sensor is opened in the middle of the placement block; two fixing seats are installed on the base, the placement block is located between the two fixing seats, and a clamping mechanism for clamping the sensor is installed on the opposite side wall of the two fixing seats.

[0007] The base is equipped with a drive mechanism for driving the two clamping mechanisms to rotate synchronously; the base is also equipped with a lifting mechanism for raising the placement block.

[0008] In some technical solutions of this utility model, the clamping mechanism includes a clamping shaft, a positioning sleeve, and an adjusting seat. The positioning sleeve is installed on the side wall opposite to the placement block of the fixed seat. The adjusting seat is located on the side of the fixed seat away from the placement block, and the base is fixedly connected to the adjusting seat. The clamping shaft extends outward after passing through the adjusting seat, the fixed seat, and the positioning sleeve in sequence. A first internal threaded sleeve is installed on the side of the adjusting seat away from the fixed seat. A first screw is provided inside the first internal threaded sleeve and is threadedly engaged with it. The first screw is connected to the clamping shaft.

[0009] In some technical solutions of this utility model, the driving mechanism includes a transmission shaft rotatably disposed between two fixed seats; a main shaft is rotatably disposed between the adjusting seat and the fixed seat, a driving gear is mounted on the main shaft, a driven gear is sleeved on the clamping shaft, the driven gear meshes with the driving gear, and the transmission shaft is connected to the main shaft for transmission.

[0010] In some technical solutions of this utility model, the lifting mechanism includes a first base plate mounted on a base, two connecting blocks, an adjusting bolt, and a mounting plate. Two first connecting rods are rotatably provided on the side walls of the connecting blocks, and the two first connecting rods are hinged to the first base plate. Two second connecting rods are rotatably provided on the side walls of the connecting blocks, and the two second connecting rods are hinged to the mounting plate. Internal threaded holes are provided on the side walls of the two connecting blocks, and the adjusting bolt is threadedly connected to the internal threaded holes.

[0011] In some technical solutions of this utility model, the driven gear is provided with a fastening screw that is connected to the clamping shaft.

[0012] In some technical solutions of this utility model, a knob is also included, which is connected to any one of the main shafts.

[0013] In some technical solutions of this utility model, a spring is installed inside the positioning sleeve, and the free end of the spring is connected to the clamping shaft.

[0014] In some technical solutions of this utility model, two placement slots communicating with the placement opening are provided on the placement block, and clamping rods adapted to the placement slots are installed on the free end of the clamping shaft.

[0015] Compared to existing technologies, this invention has at least the following advantages or beneficial effects: When clamping the sensor, the clamping end of the clamping mechanism located between the two fixed seats abuts against the outer wall of the sensor, without contacting other parts of the sensor, thus reducing obstruction to the adhesive application mechanism and improving the adhesive application effect on the sensor. Furthermore, fixing the sensor with two clamping mechanisms prevents the sensor from shifting or shaking during the adhesive application process, which could lead to poor adhesive application.

[0016] The operator turns the knob, and the main shaft connected to the knob rotates. This rotation drives another main shaft to rotate via the transmission shaft. The drive gear on the main shaft drives the driven gear on the clamping shaft to rotate. In this way, the clamping mechanism can be rotated 360° through the transmission mechanism, thus enabling a rotary adhesive application operation on the sensor. This eliminates the need to frequently change the position of the sensor and allows for continuous adhesive application. Attached Figure Description

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0024] Example

[0025] This utility model provides a small-structure sensor adhesive fixing device, such as... Figures 1-4 As shown, the system includes a base 2, which is made of steel plate and provides a stable operating platform for the adhesive application of small-structure sensors. A placement block 8 for placing the sensor is mounted on the side wall of the base 2. The placement block 8 is a block of metal with a placement opening 23 in the center that is adapted to the sensor's size. Two fixing seats 1 are mounted on the base 2, both fixed to the upper surface of the base 2 with bolts. The placement block 8 is located between the two fixing seats 1. Clamping mechanisms for holding the sensor are mounted on the opposite side walls of the two fixing seats 1. When clamping the sensor, the clamping end of the clamping mechanism between the two fixing seats 1 abuts against the outer wall of the sensor, without contacting other parts of the sensor, reducing obstruction to the adhesive application mechanism and improving the adhesive application effect on the sensor. Furthermore, the two clamping mechanisms fix the sensor in place, preventing the sensor from shifting or shaking during the adhesive application process, which could lead to poor adhesive application results.

[0026] A drive mechanism is installed on the base 2 to synchronously rotate the two clamping mechanisms. This allows the sensor, held by the two clamping mechanisms, to rotate 360° on the placement block 8, enabling rotary adhesive application without frequent changes to the sensor's position, allowing for continuous adhesive application. The base 2 also includes a lifting mechanism for raising the placement block 8. This lifting mechanism adjusts the relative vertical position of the placement block 8, ensuring better clamping of the sensor and preventing it from detaching from the two clamping mechanisms.

[0027] In some technical solutions of this utility model, the clamping mechanism includes a clamping shaft 10, a positioning sleeve 7, and an adjusting seat 9. The positioning sleeve 7 is installed on the side wall opposite to the placement block 8 of the fixed seat 1 and is fixed to the fixed seat 1 by screws. The adjusting seat 9 is located on the side of the fixed seat 1 away from the placement block 8, and the base 2 and the adjusting seat 9 are fixedly connected by bolts. The clamping shaft 10 extends outward after passing through the adjusting seat 9, the fixed seat 1, and the positioning sleeve 7 in sequence. A first internal threaded sleeve 3 is installed on the side of the adjusting seat 9 away from the fixed seat 1. The first internal threaded sleeve 3 is a nut structure and is fixed to the adjusting seat 9 by welding. The adjusting seat 9 has the same structure as the fixed seat 1. The first internal threaded sleeve 3 is provided with a first screw 4 that is threadedly engaged with it. The first screw 4 is fixedly connected to the clamping shaft 10 by welding or the first screw 4 abuts against the clamping shaft 10.

[0028] When the two clamping mechanisms clamp the sensor, the first screw 4 is tightened clockwise, and the first screw 4 pushes the clamping shaft 10 to move inward. Since the positioning sleeve 7 is fixed on the fixed seat 1, it is used to guide the clamping shaft 10 to move closer to the placement block 8, thereby clamping the sensor located on the placement block 8. When loosening, the clamping screw is loosened counterclockwise, and the clamping shaft 10 is returned to its original position under the action of the spring 12.

[0029] In some technical solutions of this utility model, the driving mechanism includes a transmission shaft 14 rotatably disposed between two fixed seats 1, the transmission shaft 14 being rotatably mounted on the two fixed seats 1 via bearings; a main shaft 6 is rotatably disposed between the adjusting seat 9 and the fixed seat 1, a driving gear 15 is mounted on the main shaft 6, and a driven gear 11 is sleeved on the clamping shaft 10, the driven gear 11 meshing with the driving gear 15, and the transmission shaft 14 is drivingly connected to the main shaft 6. The transmission shaft 14 and the main shaft 6 are drivingly connected via a coupling, or the transmission shaft 14 and the main shaft 6 are integrally formed after welding.

[0030] In some technical solutions of this utility model, the driven gear 11 is provided with a fastening screw connected to the clamping shaft 10. This prevents the driven gear 11 from shifting on the clamping shaft 10.

[0031] In some technical solutions of this utility model, a knob 5 is also included, which is connected to any one of the main shafts 6 in a transmission manner.

[0032] The operator turns knob 5, causing the main shaft 6 connected to knob 5 to rotate, which in turn drives another main shaft 6 to rotate via transmission shaft 14. The driving gear 15 on the main shaft 6 drives the driven gear 11 on the clamping shaft 10 to rotate. In this way, the clamping mechanism can be rotated 360° through the transmission mechanism, thereby performing a rotary adhesive application operation on the sensor. This eliminates the need to frequently change the position of the sensor and allows for continuous adhesive application.

[0033] In some technical solutions of this utility model, the lifting mechanism includes a first base plate 20 mounted on a base 2, the first base plate 20 being screwed to the base 2, two connecting blocks 18, an adjusting bolt 19, and a mounting plate 17. Two first connecting rods 21 are rotatably mounted on the side walls of each connecting block 18, and both first connecting rods 21 are hinged to the first base plate 20. Two second connecting rods 22 are rotatably mounted on the side walls of each connecting block 18, and both second connecting rods 22 are hinged to the mounting plate 17. Internal threaded holes are opened on the side walls of both connecting blocks 18, and the adjusting bolt 19 is threadedly connected to the internal threaded holes. A placement block 8 is fixedly connected to the mounting plate 17. The placement block 8 is fixed to the upper side of the mounting plate 17 by screws. Tightening the adjusting bolt 19 changes the relative position of the two connecting blocks 18, thereby driving the connecting rods to move, ultimately enabling the lifting mechanism to rise and fall. Adjusting the relative position of the placement block 8 in the vertical direction facilitates better clamping of the sensor by the clamping mechanism, preventing the sensor from falling off between the two clamping mechanisms.

[0034] Preferably, the placement block 8 is provided with transverse and longitudinal slots for placing the sensor. The transverse slot has a partial opening in the middle for axial positioning of the sensor. The transverse slot facilitates the clamping rod 13 on the clamping shaft 10 to clamp the sensor after positioning. The longitudinal slot is used to place the wires on the sensor.

[0035] In some technical solutions of this utility model, a spring 12 is installed inside the positioning sleeve 7, and the free end of the spring 12 is connected to the clamping shaft 10. A compression spring 12 is installed between the clamping shaft 10 and the positioning sleeve 7, which can prevent the clamping shaft 10 from making hard contact with the sensor when clamping the sensor, thus protecting the sensor.

[0036] In some technical solutions of this utility model, the placement block 8 has two placement slots 16 communicating with the placement opening 23, and each free end of the clamping shaft is equipped with a clamping rod 13 adapted to the placement slot 16. The clamping rod 13 can reduce the contact area between the clamping shaft and the sensor, thereby improving the clamping effect of this structure on the micro sensor. The clamping rod 13 and the clamping shaft 10 are integrally formed after welding.

[0037] Preferably, when applying adhesive to the micro sensor using the above structure, the operator turns the adjusting bolt 19 to change the relative position of the two connecting blocks 18, thereby driving the connecting rod to move and ultimately causing the placement block 8 located on the lifting mechanism to descend, thus avoiding interference from the placement block 8 when applying adhesive to the micro sensor.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
