Description

Technical Field

[0001] The present application relates to the technical field of photoelectric couplers, and in particular to an automatic glue sealing device for photoelectric couplers. Background Art

[0002] A photocoupler is an electrical-to-optical-to-electrical conversion device that uses light as a medium to transmit electrical signals. It consists of a light source and a light receiver. These two components are assembled in a sealed housing and isolated by a transparent insulator. The light source's pins are the input terminals, while the light receiver's pins are the output terminals. Common light sources are light-emitting diodes, and light receivers are photodiodes, phototransistors, and other types of transistors.

[0003] Before the optocoupler is injection molded, it needs to be dispensed. Since the dispensing machine used in the production of optocouplers can achieve high-speed and accurate dispensing and is simple and convenient, it has been widely used.

[0004] Currently, most dispensing machines consist of a frame with a base for dispensing materials. A dispensing device is mounted on the frame above the base. The dispensing device includes a dispensing head, a lateral movement device for moving the dispensing head horizontally, and a lifting device for moving the dispensing head vertically. The dispensing head, through the lifting and lateral movement devices, can dispense glue to the material, resulting in high dispensing efficiency.

[0005] Regarding the above-mentioned related technologies, after the optocoupler on the base is glued, the staff needs to replace the un-glueized product with the glued product. During the replacement, the glue outlet of the glue dispensing head is exposed to the air and is easily contaminated by the air, which can easily affect the quality of the subsequently glued optocoupler. Therefore, this needs to be improved. Utility Model Content

[0019] Preferably, a transparent shield is further included, and the transparent shield is used to cover the translation component, the lifting component, the dispensing head and the glue suction tube.

[0020] By adopting the above technical solution, the transparent shield can provide a relatively closed environment for the dispensing work of the photoelectric coupler, so as to reduce the contamination of the dispensing head by air and external personnel.

[0021] Preferably, the translation assembly is a linear motor or a lead screw motor.

[0022] By adopting the above technical solution, the linear motor or the lead screw motor can achieve linear motion, thereby driving the lifting component to move horizontally.

[0023] Preferably, the lifting component is a lifting cylinder, and the dispensing head is arranged on the piston rod of the lifting cylinder.

[0024] By adopting the above technical solution, when the piston rod of the lifting cylinder is extended or retracted, the dispensing head can be driven to move up and down, so that the dispensing head is close to or away from the photoelectric coupler.

[0036] Some embodiments of the present application are described in detail below with reference to the accompanying drawings. In the absence of conflict, those skilled in the art may combine and combine the different embodiments or examples and features of the different embodiments or examples shown in the present application.

[0037] The embodiment of the present application discloses an automatic sealing device for a photoelectric coupler. Figure 1The automatic glue sealing device includes a frame 1, a translation component 2, a lifting component 3, a glue dispensing head 4, a glue suction tube 5 and a negative pressure tube 6. The frame 1 serves as a carrier and is fixedly installed on the ground. The translation component 2 is installed on the frame 1, the lifting component 3 is installed on the translation component 2, and the glue dispensing head 4 is installed on the lifting component 3. The glue dispensing head 4 is used to dispense glue on the photoelectric coupler, the lifting component 3 is used to control the up and down movement of the glue dispensing head 4, and the translation component 2 is used to control the horizontal movement of the lifting component 3, thereby indirectly driving the glue dispensing head 4 to move laterally. In this embodiment, the translation component 2 is an actuator such as a linear motor or a screw motor, the lifting component 3 is a lifting cylinder, and the glue dispensing head 4 is connected to the piston rod of the lifting cylinder. When the piston rod of the lifting cylinder is extended and retracted, the glue dispensing head 4 can be driven to move up and down, so that the glue dispensing head 4 is close to or away from the photoelectric coupler.

[0038] A glue suction hose 5 is mounted on the frame 1, near the glue dispensing head 4. One end of the hose 5 is connected to a negative pressure pipe 6, which is in communication with an external air pump. This pipe is used to create a vacuum in the hose 5, while the other end is used to absorb glue from the glue dispensing head 4. A suction nozzle 7 is also mounted on the end of the hose 5 away from the negative pressure pipe 6. This nozzle increases the contact area between the hose 5 and the glue dispensing head 4, allowing for better suction of glue from the glue dispensing head 4.

[0039] The dispensing head 4, through the lifting assembly 3 and the moving assembly, can dispense glue to the photoelectric coupler. Simultaneously, the glue suction tube 5 is connected to the negative pressure tube 6. The dispensing head 4 moves to the glue suction tube 5 at regular intervals. The negative pressure tube 6 evacuates the glue suction tube 5, allowing it to draw any remaining glue into the inside, thus clearing the dispensing head 4 and preparing for the next dispensing operation. This structure is highly efficient and consistent, minimizing the impact on the dispensing quality of the photoelectric coupler.

[0040] Specifically, refer to Figure 2 The frame 1 is also equipped with a driving member 8 and a limiting frame 9. The driving member 8 is fixed to the frame 1 and is close to the suction tube 5. The limiting frame 9 is connected to the driving member 8 and can move up and down. The driving member 8 is a pneumatic cylinder that can control the limiting frame 9 to move up and down, thereby changing the relative position of the limiting frame 9 and the suction tube 5. The limiting frame 9 is also equipped with a sliding rod 10 and a limiting block 11. The sliding rod 10 is arranged in the horizontal direction. The limiting block 11 is slidably connected to the sliding rod 10 so that the staff can adjust the limiting block 11 to the appropriate position. The limiting block 11 is used to limit the suction tube 5.

[0041] In this embodiment, the limit block 11 is a split structure, comprising a first block 111 and a second block 112. The first block 111 and the second block 112 are both slidably connected to the slide bar 10 and are fastened together by fastening bolts. The first block 111 and the second block 112 are formed with through holes for the rubber suction tube 5 to pass through. The first block 111 and the second block 112 can be pressed against the rubber suction tube 5, and then the positions of the first block 111 and the second block 112 can be fixed by fastening bolts, thereby limiting the position of the rubber suction tube 5.

[0042] In addition, a transparent shield (not shown) is mounted on the frame 1 to conceal the translation assembly 2, the lifting assembly 3, the dispensing head 4, and the glue suction tube 5. The shield provides a relatively closed environment for the dispensing operation of the optocoupler, thereby reducing contamination of the dispensing head 4 from air and outside personnel.

[0043] The implementation principle of the automatic glue sealing device for photoelectric couplers in the embodiment of the present application is as follows: the glue dispensing head 4 can perform glue dispensing on the photoelectric coupler through the lifting assembly 3 and the moving assembly. At the same time, the glue suction tube 5 is connected to the negative pressure tube 6. The glue dispensing head 4 moves to the glue suction tube 5 at regular intervals. The negative pressure tube 6 vacuums the glue suction tube 5, allowing the glue suction tube 5 to suck the residual glue into the inside, thus cleaning the glue dispensing head 4 for the next glue dispensing.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
