DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0037] The following is combined with Figure 1-Figure 9 The specific implementation modes of the present invention are described in further detail.

[0038] Depend on Figure 1-Figure 9 It is given that in order to prevent glue leakage during the glue dispensing process, the present invention includes:

[0045] It should be noted that the fixture fixing mechanism 3 is used to fix the PCB transformer, and a hollow groove is provided on its upper side for the glue dispensing mechanism 6 to perform glue dispensing operation inside it;

[0046] In addition, the present invention also includes an air pressure regulating system and an air source processor, wherein the air pressure regulating system is composed of an air pressure gauge, a reflux valve knob, and a regulating valve knob, and is used to provide a high-pressure air source for use;

[0047] The gas source processor is composed of a pressure regulating nut, a pressure gauge, a filter water cup, an oil quantity regulating nut, an oil supply cup, and a connecting bracket, and is used to further purify the generated high-pressure gas;

[0048] The dispensing platform 1 is also provided with an RS232 interface. A controller is provided inside the dispensing platform 1. The RS232 interface is connected to the controller through wiring. The programmer is a handheld programmer, which is connected to the RS232 interface through an RS232 line and then electrically connected to the controller.

[0049] When in use, the PCB transformer that needs to be glued can be installed inside the clamp fixing mechanism, and then the clamp fixing mechanism 3 and the angle adjustment mechanism 5 are matched to perform the glue dispensing operation.

[0050] Further, by Figure 1 It is given that, in order to be able to adjust the front and rear position of the dispensing workpiece, the front and rear adjustment mechanism 4 includes a first screw guide rail 11 and a first sliding block 12 fixedly connected to the moving end of the first screw guide rail 11, and the angle adjustment mechanism 5 is fixedly connected to the upper side of the first sliding block 12;

[0051] Further, by Figure 1 It is given that, in order to be able to adjust the angle of the dispensing workpiece, the angle adjustment mechanism 5 includes a U-shaped frame 13, a first motor 14, and a flip seat 15, the lower side of the U-shaped frame 13 is fixedly connected to the upper side of the first sliding block 12, one side of the U-shaped frame 13 is fixedly connected to the first motor 14, the output shaft of the first motor 14 passes through the U-shaped frame 13 and is fixedly connected to the flip seat 15, and the upper side of the flip seat 15 is fixedly connected to the fixture fixing mechanism 3;

[0052] Further, by Figure 1 It is given that, in order to be able to position the dispensing position more accurately, a second screw guide rail 16 is fixedly connected to the upper side of the longitudinal support frame 2, a second sliding block 17 is fixedly connected to the movable end of the second screw guide rail 16, a dispensing support frame 18 is fixedly connected to the upper side of the second sliding block 17, a third screw guide rail 19 is fixedly connected to the front side of the dispensing support frame 18, a third sliding block 20 is fixedly connected to the movable end of the third screw guide rail 19, and the front side of the third sliding block 20 is fixedly connected to the dispensing frame 9;

[0053] It should be noted that the first screw guide 11, the second screw guide 16 and the third screw guide 19 are all ordinary screw guides or linear motors, which are prior art and will not be described in detail here. The power output positions of the first screw guide 11, the second screw guide 16, the third screw guide 19, the first motor 14 and the pulling motor 48 are all provided with programmers, and the above components and the programmers are all connected to the controller;

[0054] After starting the device, the microcontroller in the controller issues instructions, including the target position and rotation direction of the programmer, which are sent to the programmer in the form of pulse signals. After receiving the pulse signal, the programmer rotates to the specified position and adjusts the direction. At the same time, because the axis of the programmer is directly connected to the motor bearing, when the programmer rotates to the specified position, the motor will also synchronize at one position. The microcontroller uses the input capture function of the timer to monitor and capture the pulse signals from the A and B phases of the programmer in real time. By detecting the edge change (rising edge or falling edge) of the A or B phase pulse signal, the interrupt is triggered and the current state and timestamp are recorded. Furthermore, by comparing the phase difference between the A and B phase signals (A phase leads B phase by 90 degrees for forward rotation, and vice versa for reverse rotation), the rotation direction of the motor is accurately determined, and the pulses of A phase or B phase are continuously counted to accumulate the total rotation angle. Combined with the resolution of the programmer (that is, the number of pulses generated per rotation), the current specific position of the motor is calculated. This enables real-time monitoring of the motor's motion state to ensure its consistency with the preset parameters. After the user sets the motor's position, rotation direction, speed and other parameters through the buttons of the handheld programmer, a file will be formed. The file is sent to the controller via RS232 and then directly downloaded to the controller. In addition, the programmer is installed with the host computer software. Other buttons on the programmer allow the operator to control the selection of programming files, the setting of programming parameters and the monitoring of the programming process. In the programming parameter setting, the dispensing path, dispensing mode and dispensing rate can be described.

[0055] Further, by Figure 2-Figure 4 It is given that, in order to make the glue dispensing smoother, a cylinder 21 fixedly connected to the glue dispensing frame 9 is provided at the front side of the glue barrel 7, an extrusion rod 22 which can move up and down is provided inside the cylinder 21, a flow channel 23 is opened inside the glue dispensing frame 9, a glue dispensing channel 24 is connected to the front side of the flow channel 23, the lower part of the extrusion rod 22 extends to the inside of the glue dispensing channel 24, and a glue dispensing head 25 connected to the glue dispensing channel 24 is provided at the lower part of the glue dispensing frame 9;

[0056] It should be noted that the extrusion rod 22 is connected to the air source processor, and the extrusion rod 22 is lifted and lowered by the air pressure regulating system. The flow channel 23 is tilted with the front lower and the back higher, and the inclination angle is 3°, which can make the electronic glue flow more smoothly.

[0057] When in use, as the squeezing rod 22 is continuously raised and lowered, the lower end of the squeezing rod 22 continuously squeezes the melted electronic glue into the lower glue channel 24, and then the electronic glue flows out through the glue dispensing head 25 to fix the transformer components.

[0058] Further, by Figure 2-Figure 4In order to make the glue dispensing speed more uniform, an expansion channel 26 is provided inside the glue dispensing head 25, and an elastic bag 27 is fixedly connected inside the expansion channel 26. The elastic bag 27 is made of elastic material and can undergo a certain elastic deformation. A plurality of elastic pull ropes 28 are provided outside the elastic bag 27. An adjustment ring 29 that can move up and down is provided on the outer side of the glue dispensing head 25. The upper end of each elastic pull rope 28 passes through the side of the glue dispensing head 25 and is fixedly connected to the upper side of the adjustment ring 29.

[0059] During use, when the squeezing rod 22 squeezes the electronic glue downward so that it is squeezed into the lower glue channel 24, the pressure in the lower glue channel 24 will increase. At this time, the elastic bag 27 will expand outward to maintain the pressure inside the lower glue channel 24 not being too high, thereby reducing the probability of the electronic glue flowing out too quickly due to excessive squeezing pressure.

[0060] Further, by Figure 2-Figure 4 It is given that, in order to be able to adjust the glue dispensing speed, an adjustment block 30 is threadedly connected to the outer side of the glue dispensing head 25, and an annular guide rail 31 is fixedly connected to the upper side of the adjustment block 30. The lower part of the adjustment ring 29 is slidably connected to the annular guide rail 31, and two vertical rods are fixedly connected to the upper side of the adjustment ring 29. The upper side of each vertical rod is slidably connected to the glue dispensing head 25. A plurality of operating blocks 32 are fixedly connected to the outer side of the adjustment ring 29. A flow meter 33 fixedly connected to the glue dispensing frame 9 is provided at the rear side of the glue dispensing head 25. The flow meter 33 can detect the flow rate inside the glue dispensing channel 24. Furthermore, a pressure detector is also provided inside the glue dispensing channel 24 to detect the pressure inside the glue dispensing channel 24.

[0061] When in use, the adjusting block 30 can be rotated to drive the adjusting ring 29 to rise and fall through the annular guide rail 31, and then one end of the elastic rope 28 can be pulled to adjust the tightness of the elastic rope 28, and then the elastic binding force on the outside of the elastic bag 27 can be adjusted, and the size of the elastic force can be indirectly adjusted.

[0062] Further, by Figure 6-Figure 9It is given that in order to reduce the probability of glue leakage and glue dripping, the protective mechanism 10 includes a limit plate 34, a first limit rod 35, a second limit rod 36, a pulling rod 37 and a shielding cloth 38. The limit plate 34 is fixedly connected to the left side of the glue dispensing frame 9, the first limit rod 35, the second limit rod 36 and the pulling rod 37 are all rotatably connected to the limit plate 34, the side of the pulling rod 37 away from the limit plate 34 is fixedly connected to one end of the shielding cloth 38, the lower part of the left side of the limit plate 34 is fixedly connected with a first stopper 39 and a second stopper 40, the side of the first limit rod 35 close to the limit plate 34 is fixedly connected with a first limit block 41 adapted to the first stopper 39, the side of the second limit rod 36 close to the limit plate 34 is fixedly connected with a second limit block 42 adapted to the second stopper 40, and the left side of the limit plate 34 is fixedly connected with a pulling limit block 43;

[0063] When in use, when the pull rod 37 is rotated, one end of the shielding cloth 38 will be pulled to move, and at the same time, the first limiting rod 35 and the second limiting rod 36 will be driven to rotate together. During the rotation of the first limiting rod 35 and the second limiting rod 36, the second stopper 40 will cooperate with the second limiting block 42 to limit the rotation angle of the second limiting rod 36, the first stopper 39 will cooperate with the first limiting block 41 to limit the first limiting rod 35, and the limiting block 43 is pulled to limit the rotation angle of the pull rod 37, so as to limit the rotation angle of the pull rod 37, the first limiting rod 35, and the second limiting rod 36;

[0064] It should be noted that the first stopper 39 and the second stopper 40 are alternately arranged left and right, and the first limiting rod 35 will not interfere with the second stopper 40 when passing through the second stopper 40 .

[0065] Further, by Figure 6-Figure 9 It is given that, in order to automatically unfold and retract the shielding cloth 38, a first tension spring 44 is connected between the pulling rod 37 and the first limiting rod 35, a second tension spring 45 is connected between the first limiting rod 35 and the second limiting rod 36, a worm gear 46 is fixedly connected to the left side of the pulling rod 37, a worm 47 is meshed with the rear side of the worm gear 46, a pulling motor 48 is fixedly connected to the upper side of the worm 47, the output shaft of the pulling motor 48 is fixedly connected to the upper end of the worm 47, the pulling motor 48 and the first motor 14 are both servo motors, which is the prior art and will not be described in detail here, the flow meter 33 is connected to the controller, when an abnormal change in flow is detected, it can send a command to make the pulling motor 48 rotate, a shielding frame 49 is fixedly connected to the left side of the limiting plate 34, and the pulling motor 48 is fixedly connected to the inside of the shielding frame 49;

[0066] Further, by Figure 6-Figure 9It is shown that the pulling rod 37 includes a first connecting rod 50 and a second connecting rod 51. The first connecting rod 50 is rotatably connected to the second connecting rod 51 at a side away from the worm gear 46. A third tension spring 52 is connected between the first connecting rod 50 and the second connecting rod 51. The rear side of the limiting plate 34 is provided with an inclined protrusion fixedly connected to the dispensing frame 9, which can push the second connecting rod 51 to the left.

[0067] A fixing frame 53 is fixedly connected to the front side of the dispensing stroke mechanism 6, and a rotating rod 54 is rotatably connected to the front side of the fixing frame 53. One end of the shielding cloth 38 is fixedly connected to the rotating rod 54. A spring 55 is provided on both sides of the rotating rod 54. The two ends of the spring 55 are respectively fixedly connected to the inner wall of the rotating rod 54 and the fixing frame 53; a first gear lever is provided on the right side of the first limiting rod 35, and a second gear lever is provided on the right side of the second limiting rod 36;

[0068] When in use, when the pulling motor 48 rotates, the pulling rod 37 will be driven to rotate through the transmission of the worm 47 and the worm wheel 46, and then the shielding cloth 38 will be driven to unfold. At this time, the shielding cloth 38 is pulled and drives the rotating rod 54 to rotate, so that the spring 55 accumulates force. In the process of unfolding the shielding cloth 38, the first gear lever and the second gear lever will support the shielding cloth 38 under the action of the first limit rod 35 and the second limit rod 36. When the pulling motor 48 rotates in the opposite direction, the shielding cloth 38 will be retracted under the action of the spring 55.

[0069] When the present invention is used, the PCB transformer that needs to be glued can be installed inside the fixture fixing mechanism, and then the fixture fixing mechanism 3 and the angle adjustment mechanism 5 are matched to perform the glue dispensing operation. During the glue dispensing operation, the extrusion rod 22 will be raised and lowered, so that the lower end of the extrusion rod 22 continuously squeezes the melted electronic glue into the lower glue channel 24, and then the electronic glue flows out through the glue dispensing head 25. When the extrusion rod 22 squeezes the electronic glue downward to squeeze it into the lower glue channel 24, the pressure in the lower glue channel 24 will increase. At this time, the elastic bag 27 will expand outward to maintain the pressure inside the lower glue channel 24 not too high, thereby reducing the probability of the electronic glue flowing out too fast due to excessive extrusion pressure. When the flow rate is abnormal, glue blockage or glue leakage may occur. At this time, there is a risk of glue dripping onto the workpiece. The flow meter 33 sends the abnormal information to the controller. The controller sends an instruction to keep the workpiece away from the glue dispensing head 25 and rotate the pulling motor 48 at the same time. When the pulling motor 48 rotates, the pulling rod 37 is driven to rotate through the transmission of the worm 47 and the worm gear 46, and then the shielding cloth 38 is driven to unfold. At this time, the shielding cloth 38 is pulled to drive the rotating rod 54 to rotate, so that the spring 55 accumulates power. In the process of unfolding the shielding cloth 38, under the action of the first limit rod 35 and the second limit rod 36, the first gear rod and the second gear rod support the shielding cloth 38 to protect the lower side of the glue dispensing head 25.

[0070] The present invention has a novel structure, ingenious conception, and is simple and convenient to operate. Through this design, the function of preventing glue leakage during the glue dispensing process is effectively added, and the purpose of adjusting the front and rear positions of the glue dispensing workpiece is achieved. The angle of the glue dispensing workpiece can be adjusted, and the glue dispensing position can be positioned more accurately, making the glue dispensing smoother and the glue dispensing speed more uniform. The glue dispensing speed can be adjusted, reducing the probability of glue leakage and dripping, and the shielding cloth 38 can be automatically unfolded and retracted.
