Description

Technical Field

[0001] The invention belongs to the technical field of electronic component manufacturing, and in particular relates to a glue dispensing device for electronic components. Background Art

[0002] With the widespread application of electronic products, the processing accuracy and assembly process requirements of electronic components are constantly improving. During the production process, the assembly of electronic components usually requires the use of dispensing technology to fix components or provide insulation protection. Traditional dispensing devices are mostly manual or semi-automatic, which can easily lead to problems such as inaccurate dispensing position of glue, improper glue volume control, or uneven mixing, which in turn affects product quality. In addition, due to the small size of electronic components, production efficiency and operation accuracy also place higher requirements on the equipment.

[0003] Most existing dispensing equipment uses simple mechanical movements to perform dispensing operations, lacking an automated and efficient mixing mechanism. In particular, when it comes to mixing two or more glues, existing equipment is usually unable to achieve automated precise mixing. This not only affects the use of the glue, but may also affect the performance and life of electronic components due to insufficient mixing of the glue. Therefore, how to provide an automated dispensing device that can accurately control the dispensing position and glue amount and ensure that the glue is fully mixed has become a technical challenge in this field. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a glue dispensing device for electronic components, which can realize automatic and accurate control of glue dispensing and effective mixing of glue liquid.

[0005] To achieve the above object, the present invention provides the following technical solutions: A glue dispensing device for electronic components, comprising a glue dispensing bin, wherein a conveyor belt for conveying electronic components to be glued is arranged on the inner top of the glue dispensing bin; A three-axis moving platform is arranged on the top of the dispensing bin, and the three-axis moving platform is located above the conveyor belt; the three-axis moving platform includes an X-axis moving mechanism, a Y-axis moving mechanism and a Z-axis moving mechanism; The conveying direction of the conveyor belt is the same as the moving direction of the Y-axis moving mechanism; The moving end of the Z-axis moving mechanism is connected to a dispensing mechanism for dispensing glue; The dispensing mechanism includes a bracket assembly connected to the moving end of the Z-axis moving mechanism, a motor is arranged on the top of the bracket assembly, and a glue injection mechanism is arranged on the inner side of the bracket assembly, and a mixing mechanism is arranged on the output end of the glue injection mechanism; The glue enters the mixing mechanism through the glue injection mechanism and is mixed in the mixing mechanism.

[0006] Furthermore, the bracket assembly includes a connecting disk connected to the motor, a screw is inserted into the connecting disk, a glue outlet is connected to the bottom end of the screw, and a rotating shaft limit seat is connected to the bottom of the connecting disk.

[0007] Furthermore, the glue injection mechanism includes a glue injection plate connected to the bottom of the rotating shaft limiting seat, and a second through hole is formed through the side surface of the glue injection plate.

[0008] Furthermore, a glue injection guide is inserted into the second through hole; The glue injection guide comprises a connecting piece inserted into the second through hole, one end of the connecting piece is penetrated by a third through hole, and the longitudinal section of the third through hole is arranged in a stepped shape; A linkage rod is movably inserted in the third through hole, and one end of the linkage rod is connected to a sealing plug; A spring and a locking piece are sleeved on the linkage rod.

[0009] Furthermore, a first through hole is formed through the top of the glue injection disk, and the first through hole and the second through hole are interconnected.

[0010] Furthermore, the mixing mechanism includes a mixing chamber connected to the bottom of the glue injection disc, a stirring shaft is rotatably connected in the mixing chamber, and the top of the stirring shaft is connected to the output end of the motor.

[0011] Furthermore, fourth through holes are formed at equal intervals through the side surface of the mixing bin along the height direction thereof, and the fourth through holes are distributed at equal intervals around the central axis of the mixing bin; A motor is inserted into each of the fourth through holes.

[0012] Furthermore, stirring teeth are connected to the stirring shaft at equal intervals along the height direction, and the shape of the stirring teeth is set to be fan-shaped.

[0013] Furthermore, a glue outlet is provided at the bottom of the glue outlet head.

[0014] Furthermore, a through groove for heat dissipation is provided through the outer side of the rotating shaft limiting seat.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a glue dispensing device for electronic components, which can solve the problems of inaccurate glue dispensing position and inaccurate glue quantity control of electronic components in the prior art. By combining a conveyor belt with a three-axis mobile platform, the electronic components can be accurately conveyed to a predetermined glue dispensing position. The three-axis mobile platform can move in three directions, X, Y, and Z, to ensure that the glue dispensing mechanism can quickly and accurately move to the glue dispensing position of the electronic components, thereby improving the glue dispensing accuracy and efficiency. The device avoids errors that may be caused by manual operation through automated operation, thereby improving production efficiency and product quality.

[0016] The present invention also provides an effective glue liquid mixing solution, which solves the problem of uneven glue liquid mixing in the prior art.

The high-speed rotation of the stirring shaft and the stirring teeth further ensures full mixing of the glue liquid, and improves the quality of the glue liquid and the dispensing effect.

[0017] The dispensing device effectively solves the problem of insufficient glue mixing or uneven dispensing through precise glue injection and mixing mechanisms. At the same time, the fourth through hole set in the mixing chamber and the coordinated use of the motor can further ensure that the glue remains evenly distributed during the mixing process, avoid the phenomenon of glue stratification, improve the quality of the final output glue, and ensure the stability and reliability of electronic components after dispensing.

[0018] The design of the present invention not only solves the technical problems of inaccurate dispensing of electronic components and uneven mixing of glue, but also has a good heat dissipation effect. The heat dissipation grooves provided on the shaft limit seat effectively avoid the problem of glue performance degradation caused by heat accumulation during long-term operation of the equipment, thereby improving the service life and operational stability of the equipment.
