Description

Technical Field

[0002] At present, cabinet-type dispensing machines are increasingly used in the market, especially in semiconductor packaging and CCM industries. The usage scenarios are also constantly changing. Dispensing machines use glues with different viscosities according to different process requirements. After the operation is completed, the needle will be cleaned to prevent glue residue from remaining on the needle and affecting the dispensing effect, or from dripping into the equipment and causing contamination to the equipment.

[0003] The current cleaning methods are to wipe the needle with glue or to suck the glue from the needle. When wiping the needle with glue, it is easy to damage the needle because it needs to be touched, and the wiping cloth needs to be cleaned frequently, which is very cumbersome; when sucking the needle with glue, the residual glue is discharged into the glue cup through the suction force. This method can effectively clean low viscosity glue, but the single suction effect is poor when facing high viscosity glue, and the glue hanging phenomenon is still serious. Utility Model Content

The terms "first", "second", and "third" are only used to simplify the text description to distinguish similar objects, and cannot be understood as a chronological relationship between specific orders. In the description of the utility model, unless otherwise specified, "multiple" means two or more.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium. For ordinary technicians in this field, the corresponding meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The blowing and suction type glue cleaning module of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0026] See also Figures 1 to 4 As shown, the utility model provides a blowing and suction type glue cleaning module, including a base 1, a cover plate 2 and a plurality of blowing nozzles 5. The base 1 defines a accommodating chamber, and the accommodating chamber is connected to negative pressure; the cover plate 2 is covered on the base 1 to seal the accommodating chamber, and a suction nozzle 3 is provided on the cover plate 2, and the suction nozzle 3 is used to accommodate a needle and absorb glue on the needle through the negative pressure in the accommodating chamber; the plurality of blowing nozzles 5 are all arranged in the accommodating chamber, and the plurality of blowing nozzles 5 are distributed around the suction nozzle 3, and the blowing nozzle 5 is used to blow air toward the needle to blow off the glue on the needle.

[0027] In this embodiment, a glue cup 4 is provided in the base 1, and the glue cup 4 is located below the suction nozzle 3. The glue cup 4 is used to receive the glue falling from the needle. Preferably, the opening on the base 1 is larger than the outer contour of the glue cup 4. This design facilitates the glue cup 4 to receive the glue on the needle to avoid contamination of the inside of the base 1, and facilitates the removal of the glue cup 4 after opening the cover plate 2 to pour out the glue.

[0028] Preferably, an air intake pipe joint 9 is installed on the outside of the base 1, one end of the air intake pipe joint 9 is connected to the accommodating cavity, the installation position of the air intake pipe joint 9 is lower than the cup mouth of the rubber cup 4, and the other end of the air intake pipe joint 9 is connected to the negative pressure.

[0029] In other words, the interior of the accommodating chamber is connected to negative pressure through the suction pipe joint 9, and the installation position of the suction pipe joint 9 is lower than the cup mouth of the glue cup 4. This can ensure that the glue adsorbed by the negative pressure falls into the glue cup 4 instead of being directly sucked away by the suction pipe joint 9.

[0030] More preferably, a positive pressure channel 7 for introducing positive pressure is formed between the cover plate 2 and the base 1, a matching seat 21 matching with the opening of the base 1 is provided below the cover plate 2, and a plurality of connecting holes 22 are provided on the matching seat 21, and the plurality of connecting holes 22 correspond to the plurality of blowing nozzles 5 one by one, one end of the connecting hole 22 is connected to the blowing nozzle 5, and the other end of the connecting hole 22 is connected to the positive pressure channel 7, so that the plurality of blowing nozzles 5 are all connected to the positive pressure channel 7. Among them, a blowing pipe joint 8 is also installed on the outside of the base 1, one end of the blowing pipe joint 8 is connected to the positive pressure channel 7, and the other end of the blowing pipe joint 8 is connected to the positive pressure.

[0031] The advantage of this design is that all the blowing nozzles 5 are connected to the same positive pressure through the positive pressure channel 7 and the blowing pipe joint 8, and all the blowing nozzles 5 can be controlled to blow air toward the needle at the same time, avoiding blowing in a single direction causing the glue to be blown onto the inner wall of the base 1.

[0032] Preferably, two sealing rings 6 are arranged between the base 1 and the cover plate 2, and the positive pressure channel 7 is located between the two sealing rings 6. Of course, in this embodiment, two sealing grooves 11 are provided on the inner wall of the base 1, and the sealing ring 6 is located in the sealing grooves 11, and the inner wall between the two sealing grooves 11 in the base 1 and the matching seat 21 of the cover plate 2 form a positive pressure channel 7. In other words, the positive pressure channel 7 in this embodiment is annular, and the inner diameter of the inner wall between the two sealing grooves 11 in the base 1 is greater than the outer diameter of the matching seat 21 of the cover plate 2.

[0033] The base 1 and the cover plate 2 are sealed by setting two sealing rings 6, and the positive pressure channel 7 is located between the two sealing rings 6. At the same time, the airtightness of the positive pressure channel 7 can be ensured to ensure that no air leakage occurs during blowing.

[0034] In this embodiment, the number of the blowing nozzles 5 is four, and the four blowing nozzles 5 are evenly distributed around the cover plate 2. Preferably, the blowing direction of the blowing nozzle 5 is toward the bottom of the suction nozzle 3. Further, the blowing direction of the blowing nozzle 5 is directed into the glue cup 4. This design enables the gas to drive the glue to fall downward into the glue cup 4 during blowing.

[0035] During operation, when the viscosity of the glue is low, you can choose to turn on the negative pressure or positive pressure alone to clean the needle. When the viscosity of the glue is high, you can turn on the negative pressure or positive pressure alternately to perform alternate actions of sucking and blowing the glue, so as to remove the glue from the needle.

[0036] The utility model has a simple and compact structure. A base 1 and a cover plate 2 are used to form a accommodating cavity to receive glue. A needle is accommodated by a suction nozzle 3, and negative pressure is formed in the accommodating cavity to absorb the glue on the needle. In addition, a plurality of blowing nozzles 5 are provided to blow air to the needle, and the glue on the needle is blown off by positive pressure. Different concentrations of glue can be selected for use or used alternately, and the glue on the needle can be effectively cleaned, which is suitable for more application scenarios.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Therefore, although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents.
