Description

Technical Field

[0001] This invention relates to the field of optical sensor packaging technology, and more particularly to optical sensor packages. Background Technology

[0002] Optical sensors are core components in fields such as photoelectric detection, intelligent sensing, and precision imaging. Their packaging process directly determines the airtightness, lifespan, and photoelectric detection accuracy of the sensor. Dispensing encapsulation is a key process in the production and manufacturing of optical sensors. By using special encapsulation adhesive to seal and protect the sensor chip, optical path structure, and connection parts, moisture, dust, oxidation, and external interference can be effectively isolated, ensuring the long-term stable operation of the optical sensor.

[0003] Currently, traditional optical sensor packaging dispensing equipment still has some technical shortcomings in practical applications: First, the nozzle structure of existing dispensing equipment is mostly a fixed integrated design, and the nozzle spacing cannot be flexibly adjusted. It can only be adapted to the dispensing of optical sensors of a single specification and fixed arrangement. For sensor products with different spacing and different array numbers, the entire dispensing module needs to be replaced, resulting in poor equipment versatility. Secondly, conventional dispensing equipment has poor operational continuity. Most of them adopt a single-station fixed-point dispensing mode. The sensor loading, unloading, and dispensing processes are independent of each other. After the equipment completes a single dispensing operation, it needs to stop and wait for manual loading and unloading. There are gaps in the process connection, the production rhythm is not continuous, which greatly reduces the overall production efficiency and makes it difficult to adapt to the pace of industrialized mass production. Summary of the Invention

The storage tube 6 can be filled with glue. A clamping plate 9 is provided on the outer end face of the hanging plate 4. Two connecting holes 901 are opened on the surface of the clamping plate 9. A spray head 902 is fixedly installed on the outer end face of the clamping plate 9. A connecting pipe 502 is provided between the spray head 902 and the spray pipes 501. The number of spray pipes 501 is greater than... The number of nozzles 902 can be increased by the worker according to the number of sensors on the placement plate 2, and the number of fastening blocks 10 inside the horizontal slot 401 can be increased.

[0024] The working principle of this embodiment: In this invention, the operating frame 1 has two placement plates 2 inside. The two placement plates 2 are linked together by a connecting plate welded in the middle. The end face of the telescopic part of the first electric cylinder 101 is fixedly connected to the ear plate 201. After the first electric cylinder 101 is started, it can drive the two placement plates 2 to move back and forth. The left and right ends of the placement plates 2 are in contact with the inner end faces of the left and right side plates of the operating frame 1, so that the placement plates 2 will not sway left and right when moving back and forth. There are two placement plates 2. The optical sensor to be glued can be placed on the upper end face of the placement plate 2. Then the second electric cylinder 1022 drives the lifting plate 3 to move downward to perform the glue dispensing operation. After the first row of glue dispensing is completed, the second electric cylinder 1022 drives the lifting plate 3 to reset. At the same time, the first electric cylinder 1022 drives the lifting plate 3 to reset. 101 drives the placement plate 2 forward, pushing the second row of optical sensors directly below the nozzle 902. The second electric cylinder 1022 continues to operate, dispensing adhesive onto the second row of optical sensors. After the adhesive dispensing is completed on the sensors on the surface of the first placement plate 2, the second placement plate 2 is pushed below the nozzle 902. Then, the worker can remove the sensors from the surface of the first placement plate 2 and place the new sensor workpieces on top of the placement plate 2. This ensures the integrity of the adhesive dispensing operation. The worker can still ensure the integrity of the adhesive dispensing operation when picking up and loading sensors. The limiting blocks 301 at both ends of the lifting plate 3 are slidably connected to the vertical grooves 1021 on the inner end surface of the vertical plate of the hanger 102, so that the second electric cylinder 1022 drives the lifting plate. 3. During vertical movement, there will be no left or right swaying. The outer end face of the hanging plate 4 has a horizontal groove 401. A fastening block 10 is slidably connected inside the horizontal groove 401. The fastening screw 1001 at the outer end of the fastening block 10 is engaged in the connecting hole 901 on the surface of the hanging plate 9. The worker can adjust the distance between the two hanging plates 9 according to the distance between the two sensors, thus achieving the purpose of adjusting the distance between the two nozzles 902. The outer end face of the hanging plate 4 has two sets of scale lines 402. The distance between the two nozzles 902 can be quickly determined according to the scale lines 402. After tightening the nut on the surface of the fastening screw 1001, the hanging plate 9 can be fixed to the outer end face of the hanging plate 4. The inside of the storage tube 6 is filled with glue. The storage tube 6 is lower The end is fixedly connected to the horizontal tube 5. Adhesive can enter the nozzle 902 through the spray pipe 501 and connecting pipe 502 at the lower end of the horizontal tube 5. The adhesive sprayed from the nozzle 902 drips onto the sensor, completing the dispensing operation. A heating chamber 601 is formed inside the side wall of the storage tube 6. A heating wire 701 is installed inside the heating chamber 601, electrically connected to the heater 7. After the heater 7 is activated, the heating wire 701 emits heat to heat the adhesive inside the storage tube 6. A controller 8 is installed below the outer end face of the storage tube 6. A temperature sensor at the front end of the probe 801 monitors the temperature of the adhesive and sends the temperature signal to the controller 8. After analysis and processing, the controller 8 can control the activation power of the heater 7.To achieve constant temperature control of the adhesive, ensuring that the adhesive is always in optimal condition for encapsulation.
