Description
Technical Field
[0001] The utility model relates to the technical field of electronic device production, in particular to a glue dispensing machine for electronic device production. Background Art
[0002] Electronic devices refer to finished products whose molecular structures have been changed during factory production and processing, such as transistors, electron tubes, and integrated circuits. Electronic devices require glue dispensing during the production process. Some electronic devices are produced using glue dispensing machines. In order to improve the efficiency of the device in dispensing electronic devices, the device uses multiple glue dispensing tubes to work simultaneously. When in use, the electronic device is transported to the glue dispensing position through a feeding device, and then the glue dispensing position of the device is moved down to a specified position above the electronic device through a control element. Then, the pump body uses pressure to make the colloid flow out through the glue delivery tube and the glue dispensing tube, thereby performing glue dispensing on the surface of the electronic device. However, when the device dispenses glue on the surface of the electronic device, the colloid itself has a strong fluidity, and there is a lack of interception device at the glue port of the glue dispensing tube, which cannot ensure that the colloid at each glue port flows out at the same time, resulting in more or less colloid flowing out of each glue port, which easily leads to uneven glue dispensing on the surface of the electronic device.

[0014] Compared with the prior art, the beneficial effects of the utility model are: the dispensing machine for electronic device production has the following advantages:
[0015] 1.

[0016] 2. When the electronic device is glued, as the colloid continues to gather in the glue dispensing tube, the colloid pressure on the sealing seat continues to increase. Since the colloid is in liquid state, the pressure is transmitted evenly, so the three sealing seats receive the same colloid pressure. When this pressure reaches a certain level, the telescopic end of the telescopic column and the spring are stretched, and the sealing seat moves vertically downward. The blockage between the blocking seat and the conical ring is released, and the colloids at the glue dispensing ports of the three glue dispensing tubes flow out at the same time, thereby improving the uniformity of glue dispensing of electronic devices by different glue dispensing tubes of the device. It is easy to use. After the electronic device is glued, the stretching elastic force of the spring makes the sealing seat move up and reset, thereby sealing the flow of the colloid at the glue port. The glue dispensing machine for electronic device production can use pressure through elastic elements to make the colloid at the glue ports of each glue dispensing tube flow out at the same time, thereby improving the uniformity of glue dispensing on the surface of the electronic device by the device.

An electric push rod 18 is provided on the upper side of the glue dispensing frame 2, and the input end of the electric push rod 18 is electrically connected to the output end of the single-chip microcomputer 3. The telescopic end of the electric push rod 18 is fixedly connected to the upper side of the linear motor 4. When the device is used to dispense glue in the production process of electronic devices, first the single-chip microcomputer 3 starts the conveyor 19 to dispense glue to the electronic devices from right to left, and then the single-chip microcomputer 3 starts the electric push rod 18 so that its telescopic end drives the linear motor 4 to slide vertically along the slide groove, from To move the electronic device dispensing part of the device vertically, the single-chip computer 3 starts the linear motor 4 so that its movable end indirectly drives the electronic device dispensing part of the device to move longitudinally through the slide 5.

The spring 83 is movably connected to the outer end of the adjacent telescopic column 82. The blocking seat 84 is installed in cooperation with the adjacent conical ring 85. When the electronic device is glued, the single-chip computer 3 starts the water pump 13 to transport the colloid to the glue delivery tube 6 and the glue dispensing tube 7 through the hose 14. As the colloid continues to gather in the glue dispensing tube 7, the colloid pressure on the blocking seat 84 continues to increase. Since the colloid is in a liquid state, The pressure is transmitted evenly, so the three blocking seats 84 receive the same colloid pressure. When the pressure reaches a certain level, the telescopic end of the telescopic column 82 and the spring 83 are stretched, and the blocking seat 84 moves vertically downward, and the blockage between the blocking seat 84 and the conical ring 85 is released. The colloids at the dispensing ports of the three dispensing tubes 7 flow out at the same time, thereby improving the uniformity of the dispensing of electronic devices by different dispensing tubes 7 of the device.

After the electronic device is glued, the blocking seat 84 is moved up and reset by the stretching elastic force of the spring 83, thereby blocking the flow of the colloid at the glue port. The dispensing machine for electronic device production can make the colloids at the glue ports of each dispensing tube 7 flow out at the same time by using pressure through elastic elements, thereby improving the uniformity of the device on the surface of the electronic device.
[0026] Among them: it also includes a single-chip microcomputer 3, which is arranged on the front side of the dispensing frame 2. The input end of the single-chip microcomputer 3 is electrically connected to the external power supply, and the output end of the single-chip microcomputer 3 is electrically connected to the input ends of the linear motor 4, the water pump 13 and the conveyor 19 respectively, so that it is convenient to control the electrical components.
[0027] The working principle of a glue dispensing machine for electronic device production provided by the utility model is as follows: when the device is used to dispense glue during the production process of electronic devices, first, the single chip microcomputer 3 starts the conveyor 19 to dispense glue to the electronic devices from right to left, and then the single chip microcomputer 3 starts the electric push rod 18 so that its telescopic end drives the linear motor 4 to slide vertically along the slide slot, so as to vertically move the electronic device dispensing part of the device, and the single chip microcomputer 3 starts the linear motor 4 so that its moving end indirectly drives the electronic device dispensing part of the device to move longitudinally through the slide seat 5, and at the same time, the single chip microcomputer 3 starts the rangefinder 16, and the rangefinder 16 emits a light signal to illuminate the rear side of the glue delivery tube 6 and reflects It is shot back to the initial position, thereby using the light signal to transmit time and speed, so as to measure the distance between the rangefinder 16 and the glue delivery tube 6, and transmit the measurement result to the single chip microcomputer 3 in the form of an electrical signal. The single chip microcomputer 3 combines the longitudinal total length of the sliding of the mover end of the linear motor 4, and controls the linear motor 4 to accurately adjust the longitudinal position of the electronic device dispensing part of the device. At the same time, the single chip microcomputer 3 starts the rangefinder 2 17 to measure the distance between the linear motor 4 and the top wall of the dispensing frame 2 through the same principle and transmit it to the single chip microcomputer 3 in the form of an electrical signal. The single chip microcomputer 3 controls the electric push rod 18 to accurately adjust the vertical position of the electronic device dispensing part of the device. The device can effectively improve the accuracy of the dispensing of electronic devices. When dispensing electronic devices, the single chip computer 3 starts the water pump 13 to transport the colloid to the inside of the glue delivery tube 6 and the dispensing tube 7 through the hose 14. As the colloid continues to gather in the dispensing tube 7, the colloid pressure on the blocking seat 84 continues to increase. Since the colloid is in a liquid state, the pressure is evenly transmitted, so the three blocking seats 84 receive the same colloid pressure. When this pressure reaches a certain level, the telescopic end of the telescopic column 82 and the spring 83 are stretched, and the blocking seat 84 moves vertically downward, and the blockage between the blocking seat 84 and the conical ring 85 is released. The colloids at the dispensing ports of the three dispensing tubes 7 flow out at the same time, thereby improving the accuracy of the device. Different glue dispensing tubes 7 can improve the uniformity of glue dispensing of electronic devices and are easy to use. After the electronic devices are glued, the sealing seat 84 is moved up and reset through the stretching elastic force of the spring 83, thereby blocking the flow of the colloid at the glue port. The single-chip computer 3 starts the metal heating tube 9 to heat the colloid inside the device to prevent the colloid from cooling and solidifying in the hose. The single-chip computer 3 starts the temperature sensor 10 to measure the heating temperature in the hose and transmits the measurement result to the single-chip computer 3 in the form of an electrical signal. The pressure relief valve 11 is based on the balance relationship between atmospheric pressure and spring equal forces. A part of the gas will be mixed in the colloid during transportation.
