Description

Technical Field

[0001] This application pertains to pneumatic control equipment, specifically relating to a control device for automatically adjusting pneumatic pressure, applicable to the automated control of adhesive application pressure during the assembly of optical transceiver modules and the bonding of connectors. Background Technology

[0002] In the assembly of optical transceiver modules and the bonding of connectors, many locations require adhesive treatment, and the amount of adhesive used per product is very small (less than 0.02g). Two-component epoxy resin adhesives are mostly used. However, the longer this type of adhesive is mixed, the worse its flowability becomes, making flow rate monitoring impossible. Therefore, air pressure extrusion is often used for dispensing, but the amount of adhesive dispensed at the same air pressure varies greatly at different times. To ensure that the amount of adhesive injected into each product is uniform across different time periods under the same dispensing and extrusion time conditions, a fixed air pressure needs to be increased at specified intervals to maintain a consistent amount of adhesive. The challenges lie in: 1. Ensuring the consistency of air pressure adjustments each time; 2. Ensuring the consistency of the intervals between air pressure adjustments.

[0003] The existing air pressure control device is manually adjustable. First, the air source output pipe is inserted into the air inlet, and then the air inlet pipe of the dispensing device is inserted into the air outlet. The adjustment handle is manually turned. Clockwise turns increase the air pressure, and counterclockwise turns decrease the air pressure. After adjustment, the air pressure value is fixed. To change the air pressure value, the employee must manually turn the adjustment handle. Therefore, it is impossible to adjust the air pressure in a timely manner, and the air pressure cannot be accurately controlled each time it is adjusted. Utility Model Content

Detailed Implementation

[0035] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0036] refer to Figures 1-9 As shown, a control device for automatically regulating air pressure includes a pressure regulating valve group 1, an adjusting rod group 2, and a control module 3.

[0037] The control module 3 is electrically connected to the regulating rod assembly 2 and controls the movement of the rod assembly. The regulating rod assembly 2 is connected to the pressure regulating valve assembly 1 and controls the valve degree of the valve assembly. The pressure regulating valve assembly 1 is equipped with an inlet pipe 103 and an outlet pipe 107. Gas enters the pressure regulating valve assembly 1 from the inlet pipe 103. The pressure regulating valve assembly 1 changes its internal flow channel under the action of the regulating rod assembly 2, so that the gas discharged from the outlet pipe 107 has different gas pressures. The control module 3 then performs timed and amplitude-based regulation of the regulating rod assembly 2, thereby realizing timed and quantitative regulation of gas pressure.

[0038] The pressure regulating valve assembly 1, the regulating rod assembly 2, and the control module 3 are all mounted on the mounting base 4. The mounting base 4 is used to install and fix each component and module, connecting the device to form an integrated structure. The mounting base 4 is equipped with a housing 5 that covers the pressure regulating valve assembly 1, the regulating rod assembly 2, and the control module 3. The housing 5 protects each component and module and also provides an end face for installation and operation of each component and module.

[0039] The pressure regulating valve assembly 1 includes a valve body 101, an inlet air passage 102, an inlet pipe 103, an exhaust port 104, a pressure regulating chamber 105, an outlet air passage 106, an outlet pipe 107, an adjusting head 108, a compression spring 109, a sealing cap 110, and a pressure gauge 111. The valve body 101 is the main structure of the valve assembly and is fixed on the mounting base 4. The valve body 101 contains the inlet air passage 102, the pressure regulating chamber 105, and the outlet air passage 106.

[0040] The inlet of the intake channel 102 is connected to the intake pipe 103, and the middle section of the intake channel 102 is connected to the inlet of the pressure regulating chamber 105. The outlet of the intake channel 102 is provided with an exhaust port 104. The outlet of the pressure regulating chamber 105 is connected to the inlet of the outlet channel 106, and the outlet of the outlet channel 106 is connected to the outlet pipe 107. Gas enters from the intake pipe 103, then flows through the intake channel 102 into the pressure regulating chamber 105. Due to the pressure regulating valve core, there is resistance to entering the pressure regulating chamber 105, so a portion of the gas enters the pressure regulating chamber 105, and the excess gas is discharged from the exhaust port 104. The gas in the pressure regulating chamber 105 flows through the outlet channel 106 and is finally sent to the dispensing device through the outlet pipe 107. A pressure gauge 111 connected to the pressure regulating chamber 105 is provided on the valve body 101 to visually display the internal pressure of the valve assembly.

[0041] A pressure regulating valve core is movably installed at the inlet of the pressure regulating chamber 105. Specifically, the pressure regulating valve core changes the size of the inlet flow channel to control the pressure of the gas entering the pressure regulating chamber 105. The pressure regulating valve core includes an adjusting head 108, a pressure spring 109, and a sealing cap 110. The adjusting head 108 is movably installed at the inlet of the pressure regulating chamber 105. The sealing cap 110 is connected to the adjusting rod assembly 2 and slides within the pressure regulating chamber 105, sealing against the inner wall of the chamber. A pressure spring 109 is installed between the sealing cap 110 and the adjusting head 108. The movement of the adjusting rod assembly 2 causes the sealing cap 110 to slide within the pressure regulating chamber 105, and the pressure spring 109 changes the pressure acting on the adjusting head 108, thereby changing the size of the gap created by the gas pushing open the adjusting head 108, ultimately forming different pressure gases.

[0042] The adjusting rod assembly 2 includes a servo motor 201, a coupling 202, and an adjusting screw 203. The servo motor 201 is fixed to the mounting base 4 and is electrically connected to the control module 3. The drive shaft of the servo motor 201 is connected to the adjusting screw 203 via the coupling 202, which is a wedge-shaped coupling. The adjusting screw 203 is threaded into the threaded hole 112 on the valve body 101. The adjusting screw 203 extends into the valve body 101 and is movably connected to the sealing cap 110 of the pressure regulating valve core (to prevent the screw rotation from causing the sealing cap 110 to rotate synchronously).

[0043] When the servo motor 201 rotates, it drives the coupling 202 to rotate. The latter half of the coupling 202 drives the adjusting screw 203 to rotate. Since the pressure regulating valve group 1 is fixed, that is, the threaded hole 112 on the valve body 101 is also stationary, the adjusting screw 203 and the pressure regulating valve group 1 make relative movements. The adjusting screw 203 rotates within the threaded hole 112 and moves relatively left and right. When the adjusting screw 203 rotates clockwise, it moves away from the sealing cap 110 and relaxes the pressure spring 109. When it rotates counterclockwise, it tightens the sealing cap 110 and compresses the pressure spring 109. The relaxation and compression of the pressure spring 109 determine the gap between the adjusting head 108 and the valve body 101. Due to the different tensions of the pressure spring 109, the pressure on the adjusting head 108 is different. When compressed air enters the valve body from the inlet, the adjusting head 108 is pushed open by the compressed air and can enter the outlet passage to the outlet. The size of the gap between the adjusting head 108 and the valve body 101 determines the amount of compressed air entering the outlet passage. Excess compressed air in the inlet passage is discharged through the exhaust port, which can ensure the air pressure in the outlet passage.

[0044] Control module 3 includes a touch screen 301, a power connector 302, a power switch 303, a power supply 304, a PLC controller 305, and a driver 306. The touch screen 301 (SA-035F) is electrically connected to the PLC controller 305 (DVP-12SL). The touch screen 301 displays the operating status and allows for the adjustment of operating parameters. The PLC controller 305 inputs, calculates, and outputs various parameters and data, serving as the crucial control module. The PLC controller 305 is electrically connected to the driver 306 (DC9-40DC), which in turn is electrically connected to the servo motor 201 (motor 5718HB5401, current 4.4A) of the adjusting lever assembly 2, converting the electrical signals from the PLC controller 305 into final mechanical motion.

[0045] Power connector 302 is electrically connected to power supply 304 via power switch 303. Power supply 304 is electrically connected to touch screen 301, PLC controller 305 and driver 306 respectively. Power connector 302 realizes the external power supply (220V). Power switch 303 is used to control the on and off of the external power supply. Power supply 304 transforms the external power supply (24V, 2A) to power each module component.

[0046] The touchscreen 301 is located at the front of the housing 5 for easy display and operation. The power connector 302 and power switch 303 are located on the left side of the housing 5, while the air inlet pipe 103 and air outlet pipe 107 are located on the right side of the housing 5 and extend out of the housing 5 to avoid wiring interference. The pressure gauge 111 is located at the top of the housing 5 for easy observation.

[0047] Operating Procedure: First, connect the air source output pipe to the device's air inlet pipe. Then, connect the dispensing device's air inlet pipe to the air outlet pipe. Finally, connect the power supply to the device's power connector (with built-in switch) and turn it on. After the device's touchscreen is powered on, click "Settings" on the homepage to adjust the required parameters. In manual mode, use "Manual Pressurization" and "Manual Depressurization" to adjust the device's reference air pressure. Observe the pressure value indicated by the pressure gauge on the device. Once the required reference value is reached, click "Set to 0." The set value at this point is the reference air pressure value. Switch to automatic mode, and the device will start timing automatically and adjust the air pressure value according to the set parameters (adjustment principle: the servo motor rotates, driving the wedge coupling motor end (fixed) to rotate, which in turn drives the wedge coupling at the valve group end (fixed) to rotate, and drives the adjusting screw to move forward or backward to control the air pressure of the valve group. At the same time, the deflection of the air pressure gauge pointer can be observed). After reaching the set parameters, the device will automatically stop and alarm (adjustment frequency, number of times, and air pressure value accuracy can be set by yourself on the "Settings" page). After replacing the glue, click "Reset", and the device will automatically adjust and reset to the reference air pressure value. Click the "Start" button to start a new cycle.

In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.
