[0002] With the development of laser processing technology, the application fields of laser processing technology are also increasing. Laser is one of the core components of laser processing technology.

[0003] The laser includes at least one lens, which is used to adjust the optical path of the laser beam and the beam parameters of the laser beam. After the lens is adjusted to a preset position, the lens needs to be glued by a glue dispensing device to fix the lens by glue.

[0004] At present, the glue dispensing device includes a hose, and a glue outlet is provided at the end of the hose. The glue is squeezed out from the glue outlet at the end of the hose by ventilating and pressurizing the hose. However, the glue is sticky and easily adheres to the inner wall of the hose. As the glue is used, a hollow column will gradually form in the hose. After the hollow column is formed, the pressurized airflow will spray out with the glue attached to the inner wall of the hose, resulting in glue spraying, causing the inside of the laser to be contaminated by glue.

[0037] The embodiments of the present application provide a glue dispensing device and processing equipment, which are used to solve the technical problem that glue spraying easily occurs in the glue dispensing device.

[0038] In the embodiments of the present application, Figures 1 to 3 As shown, the dispensing device includes a rubber tube 1, a dispensing nozzle 2 and a suspension 3. A vent hole is provided at the end of the rubber tube 1, and the vent hole is connected to the rubber tube 1. The dispensing nozzle 2 is provided at the end of the rubber tube 1 away from the vent hole, and the dispensing nozzle 2 is connected to the rubber tube 1. The suspension 3 is provided in the rubber tube 1, and the maximum length of the suspension 3 is less than the inner diameter of the rubber tube 1.

[0039] The end of the rubber hose 1 of the embodiment of the present application is provided with an air vent, which is connected to the rubber hose 1 so that air can be inflated or sucked into the rubber hose 1 through the air vent; the glue dispensing nozzle 2 is arranged at the end of the rubber hose 1 away from the air vent, so that when the rubber hose 1 is inflated, the glue in the rubber hose 1 can be squeezed out from the glue dispensing nozzle 2, thereby achieving glue discharge; the suspension 3 is arranged in the rubber hose 1, and the maximum length of the suspension 3 is smaller than the inner diameter of the rubber hose 1, so that the suspension 3 can move freely in the rubber hose 1; when dispensing glue, air is inflated into the rubber hose 1 through the air vent, and the airflow will push the suspension 3 to move toward the glue dispensing nozzle 2 ; In the process of the suspension 3 moving toward the dispensing nozzle 2, the suspension 3 will push the glue attached to the inner wall of the hose 1 to move toward the dispensing nozzle 2, so that the glue in the hose 1 is squeezed out from the dispensing nozzle 2 through the suspension 3 to achieve dispensing; because in the process of dispensing, the suspension 3 will push the glue attached to the inner wall of the hose 1, thereby preventing the glue in the hose 1 from producing a hollow column, thereby preventing or avoiding glue spraying; after the dispensing is completed, a negative pressure can be generated in the vent hole to draw back the glue in the hose 1, so that the suspension 3 moves toward the vent hole, thereby avoiding glue dripping.

[0040] In this embodiment, when producing the glue dispensing device, glue is first injected into the rubber tube 1, and then the suspension 3 is placed into the rubber tube 1, so that the suspension 3 is located at the end of the rubber tube 1 away from the glue dispensing nozzle 2. When the rubber tube 1 is inflated, the airflow can push the suspension 3 toward the glue dispensing nozzle 2. In addition, when the suspension 3 moves toward the glue dispensing nozzle 2, the suspension 3 can push the glue attached to the inner wall of the rubber tube 1 to prevent the glue in the rubber tube 1 from generating a hollow column.

[0041] After the glue is injected into the rubber tube 1 and the suspension 3 is placed into the rubber tube 1, the end of the rubber tube 1 away from the glue dispensing nozzle 2 can be packaged to realize the manufacture of the glue dispensing device. It can be understood that the packaged end of the rubber tube 1 is provided with a vent hole.

[0042] In one embodiment, if Figure 1 and Figure 2 As shown, the difference between the maximum length of the suspension 3 and the inner diameter of the hose 1 is 0.3-0.6 mm, so as to reduce the difficulty of withdrawing the glue and the amount of glue residue on the inner wall of the hose 1, making the size of the suspension 3 more reasonable.

[0043] If the difference between the maximum length of the suspension 3 and the inner diameter of the hose 1 is too small, it means that the suspension 3 is too large, which will increase the difficulty of withdrawing the glue after the dispensing is completed. If the difference between the maximum length of the suspension 3 and the inner diameter of the hose 1 is too large, it means that the suspension 3 is too small, which will cause more glue to remain on the inner wall of the hose 1, resulting in waste.

[0044] In one embodiment, the density of the suspension 3 is 0.75-1.0 g / cm 3This is to avoid the suspension 3 having too high a density, so that the suspension 3 presses the glue out of the glue dispensing nozzle 2 by its own gravity, causing the glue dispensing process of the glue dispensing nozzle 2 to be uncontrollable.

[0045] If the density of the suspension 3 is too high, the suspension 3 will be too heavy, which will cause the suspension 3 to press the glue out of the glue dispensing nozzle 2 by its own gravity, making the glue dispensing process of the glue dispensing nozzle 2 uncontrollable. If the density of the suspension 3 is too low, the manufacturing cost of the suspension 3 will increase.

[0046] In one embodiment, the density of the suspension 3 is 0.85-0.90 g / cm 3 , to further balance the density of the suspension 3.

[0047] In one embodiment, the suspension 3 is made of polypropylene, which has a low density and low production cost and can be used as the material for making the suspension 3.

[0048] In one embodiment, if Figures 1 to 3 As shown, the suspension 3 is in the shape of a sphere, which can more comprehensively push the glue attached to the inner wall of the hose 1 to prevent the glue in the hose 1 from generating empty columns. It can also reduce the glue remaining on the inner wall of the hose 1 to reduce the waste of glue.

[0049] In this embodiment, the difference between the diameter of the suspension 3 and the inner diameter of the hose 1 is 0.3-0.6 mm.

[0050] In one embodiment, if Figure 2 and Figure 3 As shown, the inner diameter of the end of the rubber hose 1 away from the vent gradually decreases to be equal to the inner diameter of the glue dispensing nozzle 2. So that the glue in the rubber hose 1 can converge to the end of the rubber hose 1 away from the vent, and then the glue converged at the end of the rubber hose 1 away from the vent is squeezed out of the glue dispensing nozzle 2 through the suspension 3, thereby reducing the residual glue in the rubber hose 1 and reducing the waste of glue.

[0051] In one embodiment, if Figure 1 and Figure 2 As shown, the glue dispensing nozzle 2 and the rubber hose 1 are integrally arranged, so as to facilitate the manufacture of the glue dispensing nozzle 2 and the rubber hose 1, reduce the production cost, and improve the strength.

[0052] In addition, an embodiment of the present application also provides a processing equipment, which includes an inflation device, a ventilation pipe and a dispensing device. The specific structure of the dispensing device refers to the above embodiment; one end of the ventilation pipe is connected to the inflation device, and the inflation device is used to inflate the ventilation pipe, and the other end of the ventilation pipe is used to insert into the ventilation hole; since the processing equipment adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments.

[0053] The inflation device is used to inflate the ventilation pipe, and the ventilation pipe then inflates the rubber hose 1 through the ventilation holes so that the airflow introduced through the ventilation holes can push the suspension body 3. Then, the suspension body 3 is used to push the glue attached to the inner wall of the rubber hose 1 to extrude the glue from the dispensing nozzle 2 to achieve glue dispensing.

[0054] In one embodiment, the processing equipment further includes a switching device and a vacuum pumping device. An air inlet channel, an air suction channel, and an air outlet channel are provided in the switching device, and the switching device can control the air outlet channel to communicate with the air inlet channel or the air suction channel. The air inlet channel is communicated with the inflation device, and the inflation device is used to inflate the air inlet channel. The ventilation pipe is arranged in the switching device, and the ventilation pipe is communicated with the air outlet channel. The vacuum pumping device is communicated with the air suction channel, and the vacuum pumping device is used to generate a negative pressure in the air suction channel.

[0055] During glue dispensing, the switching device controls the air outlet channel to communicate with the air inlet channel, and disconnects the air outlet channel from the air suction channel. Then, the inflation device sequentially inflates the rubber hose 1 through the air inlet channel, the air outlet channel, the ventilation pipe, and the ventilation holes.

[0056] When sucking back the glue, the switching device controls the air outlet channel to communicate with the air suction channel, and disconnects the air outlet channel from the air inlet channel. Then, the vacuum pumping device sequentially generates a negative pressure in the rubber hose 1 through the air suction channel, the air outlet channel, the ventilation pipe, and the ventilation holes to suck back the glue in the rubber hose 1.

[0057] In this embodiment, the switching device can be a solenoid valve.

[0058] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application accordingly.
