[0002] In modern industrial production, sensors, as core components for information acquisition and conversion, are widely used in many fields such as automotive electronics, intelligent manufacturing, and consumer electronics. As downstream industries continue to raise their requirements for sensor performance, their assembly accuracy has become a key factor affecting product quality. The dispensing and curing processes, as important links in the sensor assembly process, are directly related to the connection stability, sealing performance, and electrical performance between the chip and the base. Existing dispensing and curing equipment for sensor assembly mostly adopts a single-station or linearly arranged multi-station design. After completing the dispensing operation of a group of sensors, the single-station equipment needs to wait for the curing lamp to finish curing the adhesive on the sensor before it can assemble the next group of sensors. This results in long production intervals and low efficiency, making it difficult to meet the needs of large-scale mass production. Utility Model Content

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0013] This utility model provides, for example Figure 1-4 The sensor assembly dispensing and curing apparatus shown includes: The workbench 1 has an annular slide rail 2 on its top and several slide blocks 3 slidably connected on the annular slide rail 2. The workbench 1 has a transmission component 9 at its bottom. The transmission component 9 can drive the slide blocks 3 to move cyclically along the annular slide rail 2, which can realize continuous alignment adjustment between different workstations of the sensor 10 during the assembly process. The dispensing assembly includes a dispensing head 4, a driving component, and a glue supply tube 6. The driving component is located on one side of the workbench 1 and has a mounting base 7 at its bottom. The top of the driving component is connected to the dispensing head 4 to control the rotation of the dispensing head 4. The dispensing head 4 is used to accurately output glue to the part of the sensor 10 to be assembled. The glue supply tube 6 is connected to the dispensing head 4 and can stably deliver a preset amount of glue to ensure the consistency of the dispensing amount. A curing component is provided on the workbench 1 and is used to uniformly cure the adhesive material at the assembly part of the sensor 10 in all directions to ensure the performance stability of the adhesive material after curing. The top of the mounting base 7 is connected to a protective box 5. The driving component is located inside the protective box 5 and is a geared motor. The protective box 5 can protect the driving component from dust, moisture and external interference. The top of the protective box 5 is rotatably connected to a swing arm 8 through a bearing, and the output shaft of the geared motor is connected to the swing arm 8. The swing arm 8 can be rotated at multiple angles by the drive of the geared motor, thereby realizing the position adjustment of the dispensing head 4. The other end of the swing arm 8 is connected to the dispensing head 4. By swinging the swing arm 8, the dispensing head 4 can be driven to the dispensing position of the sensor 10. The protective box 5 is equipped with a glue storage tank for holding glue, and a drive pump is connected to one side of the glue storage tank through a pipe. The drive pump can provide power for glue delivery. The output end of the drive pump is connected to one end of the glue supply pipe 6, and a metering valve is provided at the connection between the drive pump and the glue supply pipe 6. The metering valve can accurately control the amount of glue delivered to the dispensing head 4 each time, so as to realize quantitative dispensing. The curing assembly includes a mounting frame 11, which is connected to the workbench 1. The mounting frame 11 can adjust the height and angle of the curing assembly to meet the curing requirements of sensors 10 of different specifications. The mounting frame 11 is connected to a lamp holder 12, and two sets of curing lamps 14 are installed at the front end of the lamp holder 12. The two sets of curing lamps 14 can irradiate the adhesive from different angles to improve curing efficiency and uniformity. The surface of the curing lamp 14 is fixed with a heat sink 13 by screws. The heat sink 13 can quickly absorb the heat generated by the curing lamp 14 and dissipate it into the surrounding environment, preventing the curing lamp 14 from affecting its service life and curing effect due to excessive temperature. The top of the slide block 3 is connected to two sets of processing seats 15, and the processing seats 15 are provided with processing grooves 16. The sensor 10 is placed in the processing groove 16. The shape of the processing groove 16 is adapted to the sensor 10, which can position and fix the sensor 10 and prevent the sensor 10 from being displaced during the processing.

[0014] The sensor is assembled using a dispensing and curing device. The operator places the sensor 10 into the machining groove 16 of the machining base 15 on top of the slide 3. The contour of the machining groove 16 matches the shape of the sensor 10, limiting the horizontal displacement of the sensor 10 through a fitted design. The transmission component 9 at the bottom of the worktable 1 includes a servo motor and a rack. A gear structure is installed at the bottom of the slide 3, meshing with a closed-loop rack fixed below the annular track. When the drive gear connected to the output shaft of the servo motor rotates, the teeth of the drive gear mesh and push against the teeth of the rack, generating a horizontal driving force. Because the rack is fixed in an annular shape, the bottom of the slide 3 is equipped with... The gear can move along the track of the rack during rotation, thereby driving the entire slide 3 to move along the annular slide rail 2. The inner side of the slide rail is equipped with a positioning trigger device (through-beam photoelectric switch). This device is usually composed of a sensing element and a signal transmitter. The sensing element is installed on the inner side of the slide rail at the position corresponding to each workstation, and the signal transmitter is installed on the side of the slide 3. When the slide 3 moves to the set workstation, the signal transmitter on the slide 3 interacts with the sensing element on the inner side of the slide rail (such as blocking light, generating magnetic field changes, etc.). The sensing element then sends an electrical signal to the control system, which uses the braking of the servo motor to temporarily stop the slide 3, ensuring that subsequent processes can be accurately connected. After the slide block 3 stops at the dispensing station, the geared motor in the protective box 5 starts to operate. The output shaft of the geared motor is connected to the swing arm 8, which can drive the swing arm 8 to rotate, thereby adjusting the spatial position of the dispensing head 4 until the dispensing outlet of the dispensing head 4 is aligned with the area to be dispensed on the sensor 10. At the same time, the glue in the glue tank is sent into the glue supply pipe 6 by the drive pump. When it passes through the metering valve, the metering valve controls the flow rate of the glue by the opening and closing frequency of the internal valve core. When the glue passes through the glue supply pipe 6 to the designated position in the dispensing head 4, the glue drips onto the sensor 10 along the dispensing outlet, completing the dispensing. The swing arm 8 resets and waits for the next operation. After the sensor 10, which has completed dispensing, moves to the curing station with the slide 3, the curing lamp 14 on the lamp holder 12 is turned on. The light is focused on the adhesive part of the sensor 10. Through continuous irradiation, the adhesive undergoes a chemical reaction. Under continuous irradiation, the chemical substances inside the adhesive absorb light energy and cause changes in the molecular structure inside the adhesive. The small molecules that were originally in a liquid state are connected by chemical bonds to form a large molecular network structure, which makes the adhesive gradually change from a soft liquid state to a hard solid state, thus completing the curing operation. The heat sink 13 on the surface of the curing lamp 14 is in close contact with the lamp body. It absorbs the heat generated by the lamp body through heat conduction and then dissipates the heat to the surrounding air through the heat dissipation area of ​​the heat sink 13 itself, so as to avoid the lamp body temperature from being too high and causing unstable light intensity. Once a slide block 3 completes the curing process, the servo motor drives the gear to rotate again. The meshing transmission of the gear and rack drives the slide block 3 to continue moving along the circular slide rail 2. The vacated workstation is entered by the next slide block 3 that has completed the dispensing process. The slide block 3 without the sensor 10 is moved to the initial loading position, waiting for the new sensor 10 to be placed. Throughout the process, the meshing transmission of the gear and rack is speed-regulated through the closed-loop control of the servo motor. The actions of each workstation are linked together through the control system. The completion of the previous process will trigger the start signal of the next process, forming a continuous cyclical production process.

[0015] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
