Description

Technical Field

[0001] The utility model relates to the field of glue dispensing machines, in particular to a semi-automatic glue dispensing gun capable of reducing time delay. Background Art

[0002] At present, the types of printed circuit boards are diversified and developing rapidly, and the demand for dispensing is also increasing. The printed circuit boards produced in large quantities can be dispensed with jigs through automatic dispensing machines. However, for some printed circuit boards with small production batches, the cost of making corresponding jigs is too high, so it is inconvenient to use automated equipment. The dispensing of such products has become a problem. Many types of semi-automatic dispensing machines on the market also need to rely on jigs for positioning. In the process of semi-automatic dispensing, the switch that controls the glue output is separated from the glue gun body, the glue gun position is controlled by the hand, and the glue output switch is controlled by the foot. Therefore, it is difficult to operate when the hand-foot linkage is not proficient, there is a delay in the movement of the glue gun and the glue output, and the worker training cycle is long. Utility Model Content

[0003] The utility model aims to provide a semi-automatic glue dispensing gun with reduced time delay, so as to solve the problems existing in the above-mentioned prior art.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A semi-automatic glue dispensing gun with reduced time delay comprises a working platform, on which a glue gun and an oil-free air compressor are arranged;

[0006] The glue gun is composed of an air inlet cyclone cover, a syringe and a needle;

[0007] The syringe is bonded with an air supply switch, which is electrically connected to the oil-free air compressor through an electric wire. The top of the air intake cyclone cover is provided with an air inlet, one end of the air supply pipe is connected to the air inlet, and the other end of the air supply pipe is connected to the first air outlet of the oil-free air compressor;

[0008] The oil-free air compressor is arranged on the working platform.

[0009] By adopting the above technical solution, it can be ensured that every time the gas supply switch is pressed, the air compressor can inject compressed air into the syringe, thereby pushing the colloid out of the needle to complete the dispensing. The gas supply switch can be touched with the thumb only, which does not affect the palm of the hand holding the syringe, reducing the difficulty of dispensing, effectively increasing the dispensing efficiency and training speed. At the same time, the oil-free air compressor ensures that there will be no oil that contaminates the colloid in the compressed air, which fully meets the needs of the semiconductor manufacturing industry.

[0010] In a further embodiment, a first groove is provided on the syringe, and the first groove is used to accommodate the gas supply switch. The gas supply switch includes a switch cover, a plunger, a metal spring and a base. A switch cover is provided at the top of the base, a through hole is provided on the switch cover, and the switch cover is screwed and fixed to the base. A metal spring and a plunger are provided in the second groove of the base, and the plunger is slidably installed in the through hole on the switch cover. The bottom end of the plunger is fixedly connected to the top end of the metal spring, and the bottom end of the metal spring is provided on multiple contacts of the base.

[0011] By adopting the above technical solution, the gas supply switch can be made easy to press. Glue can be discharged by lightly pressing it, and glue discharge can be stopped by releasing the button. Only one light press is required for dispensing glue, which saves time and effort.

[0012] In a further embodiment, the gas supply switch is provided with anti-slip grooves, and the surface of the anti-slip grooves is provided with a nano coating.

[0013] By adopting the above technical solution, it can be ensured that during the long-term dispensing process, the hands will not slip due to the secretion of hand sweat. During the dispensing process, the hands may also stick to certain colloids. The nano-coating on the surface of the anti-slip pattern can make the gas switch have certain waterproof and anti-stick functions.

[0014] In a further embodiment, a sealing device is provided at the top end of the syringe, and the sealing device includes a rubber pad. The syringe is threadedly connected to the air inlet cyclone cover, and a rubber pad is provided at the inner top end of the air inlet cyclone cover.

[0015] By adopting the above technical solution, the rubber pad is used as a seal to ensure the air tightness of the syringe, prevent the syringe from leaking, ensure the stability of the glue discharge speed and glue discharge amount during dispensing, and improve the yield rate.

[0016] In a further embodiment, a pipe joint is provided between the air intake cyclone cover and the air delivery pipe, and the pipe joint is threadedly connected to the air intake cyclone cover.

[0017] By adopting the above technical solution, the sealing between the air pipe and the air inlet cyclone cover can be ensured.

[0018] In a further embodiment, the needle includes a beveled needle tip and a needle stem, wherein the beveled needle tip is arranged at the bottom end of the needle stem, and the top end of the needle stem is plugged into the syringe.

[0019] By adopting the above technical solution, colloids with higher viscosity can be adapted, and the pressure that can be tolerated is also improved.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The setting of the air supply switch on the syringe can reduce the difficulty of dispensing. The original air supply switch of the air compressor was set at the bottom of the workbench and controlled by the sole of the foot, but the hand-foot linkage is difficult and the training cycle is long. Integrating the position control and switch control of dispensing on the glue gun can greatly reduce the difficulty of training and improve work efficiency.

[0022] 2. The nano coating on the gas switch can prevent the colloid stuck on the hand from adhering to the switch after wiping the needle, and also prevent the influence of hand sweat, thereby improving the dispensing accuracy and extending the service life of the gas switch;

[0023] 3. The bevel needle tip can withstand greater pressure, making it easier to dispense high-viscosity colloids. BRIEF DESCRIPTION OF THE DRAWINGS
