Description
Technical Field
[0001] The invention relates to the technical field of glue pouring for water meter circuit boards, in particular to a highly efficient glue pouring tool for water meters. Background Art
[0002] With the continuous advancement and development of science and technology, smart water meters have emerged. Integrated circuit boards are indispensable components of smart devices. For water meters that are in constant contact with water, water has a significant impact on the integrated circuit board. However, after glue encapsulation, the water resistance of the integrated circuit board is greatly improved. Therefore, glue encapsulation of the integrated circuit board is essential in the production process of integrated circuits for smart water meters. However, in the prior art, when glue is poured into the water meter integrated circuit, the glue flows from the periphery of the circuit board when the circuit board is placed horizontally. This can easily cause bubbles to form inside the circuit board, which are difficult to remove. These bubbles significantly affect the filling quality. During use, water stains can easily enter through these bubbles, affecting the operation of the smart water meter. Furthermore, the glue filling process in the prior art is mostly manual, which is labor-intensive and inefficient. Furthermore, after filling, the glue is often left to solidify automatically, which is slow and time-consuming. Therefore, there is an urgent need to develop an efficient glue filling tool for water meters. Summary of the Invention

[0007] Furthermore, the ejection device includes a linear motor, and a push rod is provided at the output end of the linear motor. The push rod of the ejection device is aligned with the position of the water meter when the conveyor stops, which is conducive to pushing the water meter from the conveyor to the conveyor belt.

[0025] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.
[0026] A highly efficient water meter glue filling tool comprises a conveyor 1, with baffles 2 evenly arranged on the conveyor 1. The conveyor 1 includes a first horizontal section 3, an inclined section 4, and a second horizontal section 6. The angle between the inclined section 4 and the first horizontal section 3 is 45 degrees. A gentle slope section 5 for smooth transition is provided between the inclined section 4 and the second horizontal section 6. After the water meter glue is filled, the steep inclination of the inclined section 4 facilitates the removal of bubbles on the underside of the circuit board. During the upward movement, the gentle slope section 5 facilitates the slow leveling of the water meter, gradually submerging the glue in the water meter into the entire circuit board. After entering the second horizontal section 6, the glue in the water meter becomes horizontal due to gravity and is completely exhausted. A roller 7 is provided at the left end of the first horizontal section 3. A drive motor 8 is located below the roller 7. A transmission chain 9 is provided between the drive motor 8 and the roller 7. A control center 10 is located to the right of the drive motor 8. A pressure bearing 11 is provided at the connection between the first horizontal section 3 and the inclined section 4. A photoelectric sensor 12 is located to the right of the pressure bearing 11. A reflector 13 for reflecting the signal is located opposite the photoelectric sensor 12. A glue injection device 14 is located above the photoelectric sensor 12. Gantry frames 15 for supporting and fixing the glue injection device 14 are located on both sides. An ejector 16 is provided on the upper right end of the second horizontal section 6, and a conveyor belt 37 is provided on the lower right end. The ejector 16 includes a linear motor 25 with a push rod 26 at its output end. The push rod 26 of the ejector 16 is located directly opposite the position of the water meter when the conveyor 1 is stopped. The conveyor belt 37 transports the water meter to the drying device 17. The conveyor belt 37 is a horizontal rotary conveyor belt 37, and baffles 2 are provided on both sides of the conveyor belt 37. A track 28 is provided between the baffles 2. A conveyor track composed of chain plates 29 is provided on the track 28. The vertical section of the track 28 is concave, and the two sides of the chain plates 29 gradually narrow into a trapezoidal shape. A slider 30 is provided at the bottom of the chain plates 29 to cooperate with the track 28. The chain plates 29 are connected end to end by the slider 30. When the conveyor belt 37 turns, the trapezoid on one side of the chain plate 29 gradually approaches, and the other side gradually moves away.
[0027] The glue filling device 14 includes a glue storage tank 18 in the shape of a rectangular parallelepiped with a tapered lower portion. A glue injection pipe 19 is provided at the bottom of the glue storage tank 18, and a control valve 20 is installed on the glue injection pipe 19. A liquid level indicator bar 21 is provided on one side of the glue storage tank 18, and a pressure gauge 22 is provided on the side of the liquid level indicator bar 21. A sealing cover 23 is provided on the top of the glue storage tank 18. An air compressor 24 is also connected to the top of the glue storage tank 18 via a pipe. In actual use, the shape of the glue storage tank 18 is not limited. This article uses a rectangular parallelepiped as an example. The pressure gauge 22 is a control device with a pressure sensor. During operation, the air compressor 24 is used to fill the glue storage tank 18 with a certain pressure. When the pressure reaches a set value, the pressure gauge 22 controls the air compressor 24 to stop via the pressure sensor. If the pressure loss after glue injection is too large to maintain the normal glue injection volume, the air compressor 24 is activated at the starting pressure set by the pressure gauge 22 to pressurize the glue storage tank 18, thereby maintaining a constant pressure in the glue storage tank 18.
[0028] The conveyor belt 37 rotates in the drying device 17 and is arranged in several rows side by side. The drying device 17 is provided with a drying inlet 31 and a drying outlet 32. A heating device 33 is provided on the top of the drying device 17. A circulating fan 34 is provided on the upper part of the heating device 33. A return air port 35 is provided on the lower part of the heating device 33. A temperature control device 36 is provided on the inner wall of the drying device 17, and the temperature control device 36 is electrically connected to the heating device 33.
[0029] The photoelectric sensor 12, conveyor 1, conveyor belt 37, ejection device 16, and control valve 20 are electrically connected to the control center 10. The control valve 20 is actuated, and the conveyor 1 transports the water meter to the photoelectric sensor 12 through the baffle 2. The water meter blocks the photoelectric sensor 12, and the following actions are realized: the conveyor 1 stops, the conveyor belt 37 stops, the control valve 20 opens to inject glue, and the ejection device 16 is actuated.
[0030] Example 1: In actual use, the water meter is placed in sequence between the baffles 2 of the first horizontal section 3 of the conveyor 1 and close to the left baffle 2. When the conveyor 1 runs to the right, the pressure bearing 11 presses the conveyor belt so that the angle between the inclined section 4 of the conveyor 1 behind the pressure bearing 11 and the first horizontal section 3 is 45 degrees. When the water meter runs to the photoelectric sensor 12, the water meter blocks the light signal, and the device performs the following actions: (1) the conveyor 1 is paused, (2) the conveyor belt 37 is paused, (3) the control valve 20 is opened, and the water meter circuit below the injection tube 19 is filled with glue, ( 4) The ejection device 16 pushes the rod 26 to push the water meter stopped in front of the push rod 26 onto the conveyor belt 37 on the lower side of the conveyor 1; the pause time of the above-mentioned conveyor 1 and conveyor belt 37 depends on the glue filling time and the ejection time of the push rod 26. When the glue filling is completed and the ejection device 16 is retracted, the conveyor 1 and conveyor belt 37 start to operate again, and this alternating reciprocating process is repeated. Since the baffles 2 are evenly arranged on the conveyor 1, the water meter will always stop at a fixed position during transportation. Therefore, when the ejection device 16 is set at the water meter stop position, the water meter can be stopped and the push rod 26 can be pushed out.
[0031] Embodiment 2: After the water meter with glue filling is transferred to the conveyor belt 37 by the ejection device 16, the conveyor belt 37 drives the water meter into the drying device 17. The present invention adopts a horizontal rotary conveyor belt 37. The track 28 of the conveyor belt 37 is concave and is arranged in two layers parallel to each other. The upper layer is the conveying layer and the lower layer is the rotary layer. The slider 30 at the bottom of the chain plate 29 is stuck in the track 28 and can move along the track 28. The two sides of the chain plate 29 are narrowed into a trapezoidal shape to facilitate the turning of the conveyor belt. The chain plate moves to the end of the conveying layer and enters the rotary layer of the lower layer and returns to the starting position of the conveying layer. The conveyor belt 37 is stuck in the slide by the rotating gear The drive is realized on block 30. Since the conveyor belt can be bent horizontally, it is beneficial to set multiple rows of conveyor belts 37 in the drying device 17 to prevent more water meters in the drying device 17. The drying device 17 extracts the air from the lower cooling zone through the circulating fan 34 and re-enters the upper heating device 33. After heating, it enters the drying part. The temperature control device 36 on the inner wall of the drying device 17 can control the interior of the drying device 17 to maintain a constant temperature. The hot air circulation method is adopted to effectively utilize heat energy and reduce energy consumption. The dried water meter is sent out from the drying outlet 32 and collected to enter the next step.
[0032] Example 3: Refer to the attached Figure 11 , Figure 11This is the logic diagram of control center 10. When the photoelectric switch is blocked, control center 10 receives a signal and stops conveyor 1 and conveyor belt 37. After stopping, control valve 20 opens to allow glue to be poured, and ejector 16 simultaneously activates to eject the water meter. Control valve 20 is controlled by a time relay and a delay time is set by control center 10. The timer starts when the valve opens and closes after the delay time expires. The linear motor 25 of ejector 16 moves downward to its limit and then automatically returns to its initial position. After these actions are completed, conveyor 1 and conveyor belt 37 resume movement.
[0033] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
