Description

Technical Field

[0001] This invention belongs to the field of instrument and meter manufacturing technology, and in particular relates to a dispensing equipment for manufacturing intelligent instruments and meters. Background Technology

[0002] In the manufacturing of intelligent instruments and meters, potting is a key means of protecting the internal circuit board from moisture, dust and vibration. Its core requirement is to completely wrap the circuit board and components with potting compound to form a complete protective layer.

[0003] Existing potting processes mostly employ funnel-based pouring and dispensing machine injection, attempting to achieve filling by controlling the pouring speed and optimizing the adhesive viscosity. However, when dealing with high-density integrated circuit boards, areas such as the micro-gaps at the bottom of chips and the narrow spaces of pins on the circuit board are difficult to penetrate with conventional potting due to the high flow resistance of the adhesive. This prevents the adhesive from completely filling the internal circuit board of the instrument. The unfilled areas of the circuit board are susceptible to corrosion and short circuits due to environmental influences, and components are prone to falling off during vibration. Furthermore, the voids formed by air bubbles can become channels for moisture and dust penetration, significantly increasing the instrument's failure rate. In view of this, we propose a potting device for the manufacture of intelligent instruments and meters. Summary of the Invention

[0004] The purpose of this invention is to provide a dispensing device for manufacturing intelligent instruments and meters, so as to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a dispensing device for manufacturing intelligent instruments and meters, including a base, a lifting component fixedly installed on one side of the base, an extension frame fixedly installed on the lifting component, an installation panel fixedly installed on one side of the extension frame, a dispensing component fixedly installed on the installation panel, and an installation groove opened on the upper side of the base, in which a placement component is fixedly installed. The placement assembly includes a vibration spring, which is fixedly installed on the inner bottom wall of the mounting groove. A bottom shell is fixedly installed on the top of the vibration spring. A miniature vibration motor is fixedly installed on the inner bottom wall of the bottom shell. A positioning unit is fixedly installed on the upper side of the bottom shell.

[0006] In this technical solution, the instruments to be potted are placed on and fixed on the positioning unit. During potting, the controller starts the electronic potting device and simultaneously activates the micro vibration motor. The high-frequency, low-amplitude vibration generated by the micro vibration motor is amplified and buffered by the bottom shell and vibration spring, and transmitted to the entire placement assembly and the instruments on it, causing the instruments to vibrate slightly and continuously. This vibration helps the adhesive to better penetrate into the tiny gaps in the circuit board components, effectively removing air, reducing or eliminating bubbles and cavities, and forming a complete and dense protective layer. Furthermore, the vibration reduces the surface tension and flow resistance of the adhesive, enhancing its fluidity and allowing it to fill the target area more quickly and fully. Simultaneously, the vibration spring not only transmits the vibration but also acts as a buffer and support, ensuring smooth vibration without affecting the overall stability of the equipment.

[0007] In the above technical solution, the positioning unit further includes multiple connecting columns, all of which are fixedly installed on the upper side of the bottom shell. The top of each of the multiple connecting columns is fixedly installed on the same placement platform. Multiple limiting ports are opened on the upper side of the placement platform. Limiting blocks are slidably installed in each of the multiple limiting ports. An L-shaped block is fixedly installed on the upper side of each of the multiple limiting blocks. A pressure sensor is fixedly installed on one side of the L-shaped block. A silicone ball is fixedly installed on the detection end of the pressure sensor.

[0008] In this technical solution, connecting posts are installed at the four vertices of the upper side of the base shell for fixing the placement platform. Four limiting ports are provided on the upper side of the placement platform. A limiting block is slidably installed in each limiting port. An L-shaped block is fixedly installed on the upper side of each limiting block. A pressure sensor is fixedly installed on one side of each L-shaped block. A silicone ball is fixedly installed at the detection end of the pressure sensor. The instrument is placed in the center of the placement platform. A drive mechanism pushes multiple limiting blocks and their L-shaped blocks towards the center, causing the silicone balls to contact and gently press the outer edge of the instrument from different directions. The pressure sensor monitors the clamping force in real time. When the pressure reaches a preset safety value, a feedback signal is sent to the controller to stop the drive, preventing excessive clamping force from damaging the precision instrument. The silicone balls provide a flexible contact surface, avoiding scratches on the instrument surface. The application of the pressure sensor enables precise control of the clamping force, effectively preventing overpressure damage, achieving multi-directional synchronous clamping, automatically calibrating and fixing the instrument to the center of the placement platform, ensuring accurate glue application, and allowing for programmable clamping forces to adapt to instruments of different sizes and structural strengths.

[0009] In the above technical solution, the positioning unit further includes a positioning gear, which is rotatably mounted on the inner bottom wall of the bottom shell. A drive disk is fixedly mounted on the top of the positioning gear, and the drive disk has multiple arc-shaped openings. A drive block is fixedly mounted on the lower side of the limiting block, and the drive block fits into the arc-shaped opening. An electric push rod is fixedly mounted on the inner bottom wall of the bottom shell, and a positioning rack is fixedly mounted on the output end of the electric push rod. The positioning rack meshes with the positioning gear.

[0010] In this technical solution, the drive disk has four arc-shaped openings on its surface, and a drive block is fitted into each arc-shaped opening. The controller activates the electric push rod, which pushes the positioning rack to move linearly. The positioning rack drives the positioning gear meshing with it to rotate. The positioning gear drives the drive disk above to rotate synchronously. The sidewalls of the arc-shaped openings on the drive disk push the drive blocks embedded therein. Since the drive blocks are fixed to the limiting blocks, and the limiting blocks are restricted to radial sliding within the limiting openings of the placement platform, the rotational motion of the drive disk is converted into the synchronous radial linear motion of multiple limiting blocks, achieving clamping or loosening. The synchronous movement of multiple clamping points is achieved through the gear rack and the specially designed drive disk, resulting in good positioning concentricity.

[0011] In the above technical solution, the dispensing assembly further includes an electronic dispensing device, a mounting frame is fixedly installed on one side of the mounting panel, the electronic dispensing device is slidably installed in the mounting frame, and a cleaning unit is fixedly installed on the mounting panel.

[0012] In this technical solution, an electronic dispensing device is used to store and precisely pump adhesive. It is mounted on a mounting panel via a mounting frame and can move up and down under the drive of a lifting assembly to adjust the distance between the dispensing nozzle and the workpiece. A cleaning unit is used to pre-treat the workpiece before dispensing, and the electronic dispensing device enables precise control of the adhesive volume.

[0013] In the above technical solution, the cleaning unit further includes a cleaning air gun, which is fixedly installed on one side of the mounting panel.

[0014] In this technical solution, the cleaning air gun is connected to an external air source, and the nozzle is bent towards the glue-filling area. Before glue filling, the control system is activated to spray high-pressure gas to blow away dust, debris and other impurities from the glue-filling area of ​​the instrument, ensuring that the glue-filling surface is clean. Pre-treatment cleaning can effectively prevent impurities from mixing into the glue or affecting the adhesion of the glue layer, thus improving product quality.

[0015] In the above technical solution, the cleaning unit further includes an opening and closing plate, the surface of which has an opening and closing opening, the surface of which has a through opening, the opening and closing plate being slidably installed in the through opening, a telescopic rack being fixedly installed on one side of which, a motor slot being provided on the surface of the mounting panel, an adjusting motor being fixedly installed in the motor slot, an adjusting gear being fixedly installed at the output end of the adjusting motor via a rotating shaft, the adjusting gear meshing with the telescopic rack, a lifting rack being fixedly installed on one side of the electronic dispensing device, the lifting rack meshing with the adjusting gear, and a distance sensor being fixedly installed on one side of the mounting panel.

[0016] In this technical solution, the regulating motor starts, driving the regulating gear to rotate. The regulating gear simultaneously drives the lifting rack and the telescopic rack. The lifting rack drives the electronic dispensing nozzle to move vertically. The telescopic rack drives the opening and closing plate to slide horizontally. Through precise design of the gear and rack parameters and the position of the opening and closing ports on the opening and closing plate, a linkage is achieved: when cleaning is required, the regulating motor raises the electronic dispensing nozzle to a high position, while the opening and closing plate slides to align the opening and closing ports with the air path of the cleaning air gun, opening the air path for cleaning. After cleaning, the regulating motor reverses, the electronic dispensing nozzle descends to the working position, and the opening and closing plate slides to misalign the opening and closing ports, closing the air path. A distance sensor is used to assist in positioning, achieving separation of the cleaning and dispensing actions in time and space, improving cleaning efficiency while preventing impurities from contaminating the dispensing nozzle during cleaning.

[0017] In the above technical solution, the lifting assembly further includes a lifting frame, which is fixedly installed on one side of the base. A lifting groove is provided on one side of the lifting frame, and a lifting block is slidably installed in the lifting groove. One side of the lifting block is fixedly connected to one side of the extension frame.

[0018] In this technical solution, the lifting block moves vertically along the lifting groove of the lifting frame, thereby driving the entire extension frame, mounting panel, and the glue-filling assembly and cleaning unit on it to rise and fall together, achieving coarse adjustment to adapt to different working environments or workpieces.

[0019] In the above technical solution, the lifting assembly further includes a lifting screw, a rotating hole is provided on the upper side of the lifting frame, the non-threaded area of ​​the lifting screw is rotatably installed in the rotating hole, the lifting block is screwed onto the threaded area of ​​the lifting screw, and a lifting motor is fixedly installed at the top of the lifting frame, the output end of the lifting motor is coaxially fixedly connected to the top of the lifting screw.

[0020] In this technical solution, the lifting motor starts, driving the lifting screw to rotate. Since the lifting block and the lifting screw are threaded together, and their movement is restricted by the lifting groove, the rotation of the lifting screw is converted into precise vertical linear motion of the lifting block.

[0021] In the above technical solution, a silicone ring is further fixedly installed on the inner wall of the mounting groove, and there is a gap between the silicone ring and the placement platform.

[0022] In this technical solution, when vibrating under the drive of a miniature vibration motor, the silicone ring surrounds the placement platform but does not directly contact it. Its main function is to prevent the placement platform from directly colliding with the hard inner wall of the mounting groove when the amplitude is too large. At the same time, it can also absorb some vibration energy, reduce the transmission to the base, avoid hard collisions between vibrating components and fixed components, and protect the equipment structure.

[0023] In the above technical solution, a controller is further fixedly installed on the upper side of the base.

[0024] In this technical solution, the controller is electrically connected to all electrical components, including pressure sensors, distance sensors, electric actuators, miniature vibration motors, lifting motors, adjusting motors, and electronic dispensing devices. Based on a preset program or sensor feedback, the controller coordinates and controls the sequence and parameters of each component's actions, achieving fully automated production from positioning, cleaning, and lifting to dispensing and vibration, ensuring stable product quality.

[0025] The beneficial effects of this invention are: 1. In this intelligent instrument manufacturing glue-drinking equipment, during glue-drinking, the controller simultaneously turns on the micro vibration motor to perform periodic slight vibration. Under the action of the vibration spring, the micro vibration motor causes the bottom shell to vibrate, thereby causing the instrument to vibrate slightly, assisting in glue filling and preventing the formation of cavities.

[0026] 2. This intelligent instrument manufacturing dispensing equipment uses a cleaning air gun to spray high-pressure cleaning gas to clean the dispensing area of ​​the instrument. After cleaning, the output of the adjusting motor drives the adjusting gear to rotate via a rotating shaft. The adjusting gear drives the lifting rack to move vertically, which in turn drives the electronic dispensing device downwards, aligning the dispensing nozzle of the electronic dispensing device with the dispensing area of ​​the instrument. During the downward movement of the electronic dispensing device, the adjusting gear simultaneously drives the telescopic rack to move horizontally, which in turn drives the opening and closing plate to move horizontally, causing the opening and closing port on the opening and closing plate to misalign with the air inlet channel of the cleaning air gun, cutting off the air intake. When the electronic dispensing device is at its lowest position, the controller starts the electronic dispensing device, dispensing a measured amount of glue into the instrument. This pre-cleaning process pre-treats the inside of the instrument to be dispensed, preventing impurities from affecting the dispensing quality. Simultaneously, during cleaning, the electronic dispensing device is retracted upwards to prevent cleaning impurities from contaminating the dispensing nozzle.

[0027] 3. This intelligent instrument manufacturing dispensing equipment uses a controller to activate an electric push rod, which in turn drives a positioning rack to rotate. The positioning rack then drives a positioning gear to rotate, which in turn drives a drive disc to rotate. The drive disc, through an arc-shaped opening, drives multiple drive blocks to move, and under the combined action of limit openings, drives corresponding limit blocks to move. These limit blocks then drive corresponding L-shaped blocks to move, which in turn drive pressure sensors to move. The pressure sensors then drive silicone balls to move, causing the silicone balls to move toward the instrument being dispensed and press against its surface to center it, thus achieving automatic positioning and preventing positional deviation during dispensing.

[0030] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0031] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0032] Example 1: This example provides a dispensing equipment for manufacturing intelligent instruments and meters, including a base 1, a lifting component fixedly installed on one side of the base 1, an extension frame 8 fixedly installed on the lifting component, an installation panel 9 fixedly installed on one side of the extension frame 8, a dispensing component fixedly installed on the installation panel 9, and an installation groove opened on the upper side of the base 1, in which a placement component is fixedly installed. The placement assembly includes a vibration spring 10, which is fixedly installed on the inner bottom wall of the mounting groove. A bottom shell 12 is fixedly installed on the top of the vibration spring 10. A miniature vibration motor 11 is fixedly installed on the inner bottom wall of the bottom shell 12. A positioning unit is fixedly installed on the upper side of the bottom shell 12.

[0033] The instruments to be glued are placed on the positioning unit and fixed. During glue application, the controller 4 starts the electronic glue applicator 27 and simultaneously starts the micro vibration motor 11. The high-frequency, low-amplitude vibration generated by the micro vibration motor 11 is amplified and buffered by the base shell 12 and the vibration spring 10, and transmitted to the entire placement assembly and the instruments on it, causing the instruments to vibrate slightly and continuously. This vibration helps the glue to better penetrate into the tiny gaps of the circuit board components, effectively removing air, reducing or eliminating bubbles and cavities, and forming a complete and dense protective layer. The vibration also reduces the surface tension and flow resistance of the glue, enhancing its fluidity and allowing it to fill the target area more quickly and fully. At the same time, the vibration spring 10 not only transmits the vibration but also acts as a buffer and support, ensuring that the vibration is stable and does not affect the overall stability of the equipment.

[0034] Example 2: This example provides a dispensing equipment for manufacturing intelligent instruments and meters. In addition to the technical solutions of the above examples, it also has the following technical features: the positioning unit includes multiple connecting columns 18, all of which are fixedly installed on the upper side of the bottom shell 12. The top of the multiple connecting columns 18 is fixedly installed on the same placement platform 2. Multiple limiting ports 19 are opened on the upper side of the placement platform 2. Limiting blocks 21 are slidably installed in the multiple limiting ports 19. L-shaped blocks 22 are fixedly installed on the upper side of the multiple limiting blocks 21. A pressure sensor 23 is fixedly installed on one side of the L-shaped block 22. A silicone ball 24 is fixedly installed on the detection end of the pressure sensor 23.

[0035] The base shell 12 has four connecting posts 18 at its four vertices for fixing the placement platform 2. The placement platform 2 has four limiting ports 19 on its upper side. A limiting block 21 is slidably installed in each limiting port 19. An L-shaped block 22 is fixedly installed on the upper side of each limiting block 21. A pressure sensor 23 is fixedly installed on one side of each L-shaped block 22. A silicone ball 24 is fixedly installed at the detection end of the pressure sensor 23. The instrument is placed in the center of the placement platform 2. A drive mechanism pushes multiple limiting blocks 21 and their L-shaped blocks 22 towards the center, causing the silicone balls 24 to contact and gently press the outer edge of the instrument from different directions. The pressure sensor 23 monitors the clamping force in real time. When the pressure reaches a preset safety value, it sends a feedback signal to the controller 4 to stop the drive, preventing excessive clamping force from damaging the precision instrument. The silicone balls 24 provide a flexible contact surface to avoid scratching the instrument surface. The application of pressure sensor 23 enables precise control of clamping force, effectively preventing overpressure damage, achieving multi-directional synchronous clamping, automatically calibrating and fixing instruments to the center of the placement platform 2, ensuring accurate glue dispensing position, and allowing different clamping forces to be set through the program to adapt to instruments of different sizes and structural strengths.

[0036] Example 3: This example provides a dispensing equipment for manufacturing intelligent instruments and meters. In addition to the technical solutions of the above examples, it also has the following technical features: the positioning unit further includes a positioning gear 15, which is rotatably mounted on the inner bottom wall of the bottom shell 12. A drive disk 16 is fixedly mounted on the top of the positioning gear 15. The drive disk 16 has multiple arc-shaped openings 17. A drive block 20 is fixedly mounted on the lower side of the limiting block 21. The drive block 20 fits into the arc-shaped openings 17. An electric push rod 13 is fixedly mounted on the inner bottom wall of the bottom shell 12. A positioning rack 14 is fixedly mounted on the output end of the electric push rod 13. The positioning rack 14 meshes with the positioning gear 15.

[0037] The drive disk 16 has four arc-shaped openings 17 on its surface, each containing a drive block 20. The controller 4 activates the electric push rod 13, which pushes the positioning rack 14 to move linearly. The positioning rack 14 drives the positioning gear 15, which meshes with it, to rotate. The positioning gear 15 then drives the drive disk 16 above to rotate synchronously. The sidewalls of the arc-shaped openings 17 on the drive disk 16 push the embedded drive blocks 20. Because the drive blocks 20 are fixed to the limiting blocks 21, and the limiting blocks 21 are confined within the limiting openings 19 of the placement platform 2 and can only slide radially, the rotational motion of the drive disk 16 is converted into synchronous radial linear motion of multiple limiting blocks 21, achieving clamping or loosening. The synchronous movement of multiple clamping points is achieved through the gear rack and the specially designed drive disk 16, resulting in good concentricity.

[0038] Example 4: This example provides a dispensing device for manufacturing intelligent instruments and meters. In addition to the technical solutions of the above examples, it also has the following technical features: the dispensing assembly includes an electronic dispensing device 27, a mounting frame 26 is fixedly installed on one side of the mounting panel 9, the electronic dispensing device 27 is slidably installed in the mounting frame 26, and a cleaning unit is fixedly installed on the mounting panel 9.

[0039] The electronic dispensing device 27 is used to store and precisely pump glue. It is mounted on the mounting panel 9 via the mounting frame 26 and can move up and down under the drive of the lifting assembly to adjust the distance between the dispensing nozzle and the workpiece. The cleaning unit is used to pre-treat the workpiece before dispensing. The electronic dispensing device 27 enables precise control of the glue volume.

[0040] Example 5: This example provides a dispensing equipment for manufacturing intelligent instruments and meters. In addition to the technical solutions of the above examples, it also has the following technical features: the cleaning unit includes a cleaning air gun 30, which is fixedly installed on one side of the mounting panel 9.

[0041] Among them, the cleaning air gun 30 is connected to an external air source, and the nozzle is bent towards the glue-filling area. Before glue filling, it is turned on by the control system to spray high-pressure gas to blow away dust, debris and other impurities in the glue-filling area of ​​the instrument and meter, ensuring that the glue-filling surface is clean. Pre-treatment cleaning can effectively prevent impurities from mixing into the glue or affecting the adhesion of the glue layer, thus improving product quality.

[0042] Example 6: This example provides a dispensing device for manufacturing intelligent instruments and meters. In addition to the technical solutions of the above examples, it also has the following technical features: the cleaning unit further includes an opening and closing plate 34, the surface of which has an opening and closing opening 35, the surface of the cleaning air gun 30 has a through opening, the opening and closing plate 34 is slidably installed in the through opening, a telescopic rack 33 is fixedly installed on one side of the opening and closing plate 34, a motor slot is opened on the surface of the mounting panel 9, an adjusting motor 31 is fixedly installed in the motor slot, the output end of the adjusting motor 31 is fixedly installed with an adjusting gear 32 through a rotating shaft, the adjusting gear 32 meshes with the telescopic rack 33, a lifting rack 28 is fixedly installed on one side of the electronic dispensing device 27, the lifting rack 28 meshes with the adjusting gear 32, and a distance sensor 29 is fixedly installed on one side of the mounting panel 9.

[0043] The system involves starting the regulating motor 31, which drives the regulating gear 32 to rotate. The regulating gear 32 simultaneously drives the lifting rack 28 and the telescopic rack 33. The lifting rack 28 drives the electronic dispensing nozzle 27 to move vertically. The telescopic rack 33 drives the opening / closing plate 34 to slide horizontally. Through precise design of the gear and rack parameters and the position of the opening / closing port 35 on the opening / closing plate 34, a linkage mechanism is achieved: when cleaning is required, the regulating motor 31 raises the electronic dispensing nozzle 27 to a high position, while the opening / closing plate 34 slides to align the opening / closing port 35 with the air path of the cleaning air gun 30, opening the air path for cleaning. After cleaning, the regulating motor 31 reverses, the electronic dispensing nozzle 27 descends to the working position, and the opening / closing plate 34 slides to misalign the opening / closing port 35, closing the air path. The distance sensor 29 is used for auxiliary positioning, achieving separation of the cleaning and dispensing actions in time and space, improving cleaning efficiency while preventing impurities from contaminating the dispensing nozzle during cleaning.

[0044] Example 7: This example provides a dispensing equipment for manufacturing intelligent instruments and meters. In addition to the technical solutions of the above examples, it also has the following technical features: the lifting assembly includes a lifting frame 5, which is fixedly installed on one side of the base 1. A lifting groove is provided on one side of the lifting frame 5, and a lifting block 6 is slidably installed in the lifting groove. One side of the lifting block 6 is fixedly connected to one side of the extension frame 8.

[0045] The lifting block 6 moves vertically along the lifting groove of the lifting frame 5, thereby driving the entire extension frame 8, the mounting panel 9, and the glue-filling assembly and cleaning unit on it to rise and fall together, so as to achieve coarse adjustment to adapt to different working environments or workpieces.

[0046] Example 8: This example provides a dispensing equipment for manufacturing intelligent instruments and meters. In addition to the technical solutions of the above examples, it also has the following technical features: the lifting assembly includes a lifting screw 25, a rotating hole is provided on the upper side of the lifting frame 5, the non-threaded area of ​​the lifting screw 25 is rotatably installed in the rotating hole, the lifting block 6 is screwed onto the threaded area of ​​the lifting screw 25, and a lifting motor 7 is fixedly installed at the top of the lifting frame 5. The output end of the lifting motor 7 is coaxially fixedly connected to the top of the lifting screw 25.

[0047] When the lifting motor 7 is started, it drives the lifting screw 25 to rotate. Since the lifting block 6 and the lifting screw 25 are threaded together, and its movement is restricted by the lifting groove and cannot rotate, the rotation of the lifting screw 25 is converted into the precise vertical linear movement of the lifting block 6.

[0048] Example 9: This example provides a dispensing equipment for manufacturing intelligent instruments and meters. In addition to the technical solutions of the above examples, it also has the following technical features: a silicone ring 3 is fixedly installed on the inner wall of the mounting groove, and there is a gap between the silicone ring 3 and the placement platform 2.

[0049] When the device vibrates under the drive of the micro vibration motor 11, the silicone ring 3 surrounds the placement platform 2 but does not directly contact it. Its main function is to prevent the placement platform 2 from directly colliding with the hard inner wall of the mounting groove when the amplitude is too large. At the same time, it can also absorb some vibration energy, reduce the transmission to the base 1, avoid hard collisions between the vibrating parts and the fixed parts, and protect the equipment structure.

[0050] Example 10: This example provides a dispensing equipment for manufacturing intelligent instruments and meters. In addition to the technical solutions of the above examples, it also has the following technical features: a controller 4 is fixedly installed on the upper side of the base 1.

[0051] The controller 4 is electrically connected to all electrical components, including the pressure sensor 23, distance sensor 29, electric actuator 13, miniature vibration motor 11, lifting motor 7, adjusting motor 31, and electronic dispensing device 27. Based on a preset program or sensor feedback, it coordinates and controls the sequence and parameters of each component's actions, achieving fully automated production from positioning, cleaning, and lifting to dispensing and vibration, ensuring stable product quality.

[0052] Working principle: When using the device, connect the electronic glue dispensing device 27 to the glue source to be dispensed, and connect the top of the cleaning air gun 30 to the air supply source. First, place the instrument to be dispensed on the placement platform 2 between the four silicone balls 24. Then, start the electric push rod 13 through the controller 4. The electric push rod 13 drives the positioning rack 14 to move, the positioning rack 14 drives the positioning gear 15 to rotate, the positioning gear 15 drives the drive disk 16 to rotate, and the drive disk 16 drives multiple drive blocks 20 to move through the arc-shaped opening 17, and the limit opening 19 works together to move the drive blocks 20. The electric push rod 13 moves down, causing the corresponding limit block 21 to move. Multiple limit blocks 21 move the corresponding L-shaped block 22, which in turn moves the pressure sensor 23. The pressure sensor 23 moves the silicone ball 24, causing multiple silicone balls 24 to move toward the instrument being potted and press its surface to center it. When the center position is reached, the electric push rod 13 continues to work. At this time, the silicone ball 24 generates pressure, which is monitored by the pressure sensor 23. After the pressure increases, the controller 4 stops the electric push rod 13, thus completing the positioning of the instrument. Next, the controller 4 starts the lifting motor 7. The output of the lifting motor 7 drives the lifting screw 25 to rotate. The lifting screw 25 drives the lifting block 6 to move downward. The lifting block 6 drives the extension frame 8 to move downward. The extension frame 8 drives the mounting panel 9 to move downward. The mounting panel 9 drives the mounting frame 26 to move downward. The mounting frame 26 drives the electronic dispensing device 27 to move downward. At the same time, the distance sensor 29 measures the distance between itself and the instrument. When the appropriate distance is reached, a signal is sent to the controller 4. The controller 4 stops the lifting motor 7, so that the electronic dispensing device 27 stops lifting. The cleaning air gun 30 sprays high-pressure cleaning gas to clean the glue-filling area of ​​the instrument, removing internal impurities. After cleaning, the controller 4 starts the adjusting motor 31. The output of the adjusting motor 31 drives the adjusting gear 32 to rotate via a shaft. The adjusting gear 32 drives the lifting rack 28 to move vertically. The lifting rack 28 drives the electronic glue dispenser 27 to move downward, aligning the glue nozzle of the electronic glue dispenser 27 with the glue-filling area of ​​the instrument. During the downward movement of the electronic glue dispenser 27, the adjusting gear 32 simultaneously drives the telescopic rack 33 to move horizontally. The telescopic rack 33 drives the opening and closing plate 34 to move horizontally, causing the opening and closing port 35 on the opening and closing plate 34 to be misaligned with the air inlet channel of the cleaning air gun 30, cutting off the air intake. When the electronic glue dispenser 27 is in the lowest position, the controller 4 starts the electronic glue dispenser 27 to fill a certain amount of glue into the instrument. During glue filling, the controller 4 simultaneously turns on the micro vibration motor 11 to perform periodic slight vibration. Under the action of the vibration spring 10, the micro vibration motor 11 causes the bottom shell 12 to vibrate, thereby causing the instrument to vibrate slightly, assisting in glue filling and preventing the formation of cavities.
