Description

Technical Field

[0001] This utility model relates to the field of electronic component dispensing technology, specifically to a high-precision dispensing device for electronic components. Background Technology

[0002] Electronic components require dispensing during production. Dispensing is a process, also known as gluing, coating, potting, or dripping, in which electronic adhesives, oils, or other liquids are applied, potted, or dripped onto the product to achieve functions such as adhesion, potting, insulation, fixation, and surface smoothing. Dispensing of electronic components requires the use of dispensing equipment.

[0003] The existing dispensing devices use a fixed height for the dispensing cylinder, which limits the application when the thickness of the electronic components or the volume and height of the components in the dispensing area differs. This can also affect the dispensing accuracy. In low-temperature conditions, when the dispensing device has been idle for a period of time or has not been used for an extended period, the adhesive inside the dispensing mechanism often precipitates or hardens slightly. In such cases, the adhesive may not be able to be dispensed properly during use. Furthermore, the existing dispensing equipment lacks a positioning structure for electronic components, making it prone to deviations during dispensing.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose a high-precision dispensing device for electronic components.

[0006] To achieve the above objectives, this utility model provides a high-precision dispensing device for electronic components, comprising a fixed base plate, a support plate on the fixed base plate, two positioning clamping plates connected to the support plate via an adjustable clamping structure, an elastic protective plate on the inner wall of the positioning clamping plate, electric telescopic rods symmetrically mounted on one end of the fixed base plate, a rapid drying mechanism mounted on the fixed base plate at one end of the electric telescopic rods, a support crossbar fixedly connected to the top of each electric telescopic rod, an X-axis moving module connected between the other ends of the support crossbars, a dispensing cylinder connected to the X-axis moving module, and a dispensing head connected to the bottom end of the dispensing cylinder.

[0008] Preferably, the adjusting clamping structure includes a drive rod disposed within the support plate. One end of the drive rod is mounted on the inner wall of the support plate via a bearing, and the other end of the drive rod movably passes through the support plate and is connected to a forward and reverse motor. The drive rod is provided with two opposite bolt areas.

[0009] Preferably, each bolt area is threaded with a threaded sleeve, and the support plate is symmetrically provided with guide grooves. The threaded sleeve is fixedly connected to a guide connecting post that passes through the guide groove and is connected to the positioning clamping plate.

[0010] Preferably, the rapid drying mechanism includes an outer shell 1 mounted on the fixed base plate, an outer shell 2 integrally connected to the back of the outer shell 1, a motor installed at one end inside the outer shell 2, blades connected to the output end of the motor, and a dust filter embedded in the outer shell 2. An electric heating mesh is installed inside the outer shell 1, and a protective mesh is installed on the outside of the electric heating mesh.

[0011] Preferably, the constant temperature glue storage mechanism includes a glue storage tank mounted on the mounting plate. The bottom of the glue storage tank is integrally connected to a heat insulation outer layer. An electric heating plate is disposed inside the heat insulation outer layer, and a heat-conducting plate extending into the glue storage tank is attached to the electric heating plate. A delivery pump is installed at the bottom of the glue storage tank, and the output end of the delivery pump is connected to a glue outlet pipe communicating with the delivery pipeline.

[0013] This utility model provides a high-precision dispensing device for electronic components, with the following advantages:

[0014] By setting a support plate on a fixed base plate, and connecting two positioning clamping plates on the support plate through an adjustable clamping structure, when electronic components need to be dispensed, the electronic components can be placed between the two positioning clamping plates, and clamped by adjusting the clamping structure. The elastic protective plate can protect the electronic components from damage, and the fast drying mechanism can quickly dry and solidify the dispensed electronic components. The X-axis moving module on the support crossbar is raised and lowered by an electric telescopic rod, so that the dispensing cylinder can be raised and lowered to approach the dispensing point. The X-axis moving module allows the dispensing cylinder to be translated. This utility model has a simple structure, which is convenient for centering and clamping electronic components of different specifications. It also has a protective effect during clamping, ensuring that the position of the electronic components does not shift during dispensing. At the same time, it can dry quickly after dispensing, eliminating the need for separate drying and solidification of the glue at the dispensing point, and preventing problems such as insufficient glue and glue solidification.

[0025] In one embodiment, please refer to the appendix to the specification. Figure 2 As shown, the adjusting clamping structure 3 includes a drive rod 13 disposed within the support plate 2.

An inlet 33 is provided on the glue storage tank 27. The electric heating plate 29 generates heat, which is then transferred to the heat-conducting plate 30, causing the heat-conducting plate 30 to heat the glue inside the glue storage tank 27, especially at the bottom, preventing the glue from solidifying. The delivery pump 31 delivers the glue from the glue storage tank 27 into the delivery pipeline 11 through the glue outlet pipe 32. The inlet 33 facilitates timely addition of glue, and when not in use, the inlet 33 can be sealed with a sealing cap (not shown in the figure).

[0028] In practical applications, a support plate 2 is set on a fixed base plate 1, and two positioning clamping plates 4 are connected to the support plate 2 through an adjustable clamping structure 3. When it is necessary to dispense electronic components, the electronic components can be placed between the two positioning clamping plates 4, and the clamping structure 3 can be adjusted to clamp them. The elastic protective plate can protect the electronic components from damage, and the fast drying mechanism 6 can quickly dry and solidify the dispensed electronic components. The electric telescopic rod 5 drives the X-axis moving module 8 on the support crossbar 7 to rise and fall, thereby raising and lowering the dispensing cylinder 9 as a whole, so that it can approach the dispensing point. The X-axis moving module 8 allows the dispensing cylinder 9 to move horizontally. This utility model has a simple structure, which is convenient for centering and clamping electronic components of different specifications. It also has a protective effect during clamping, ensuring that the position of the electronic components will not shift during dispensing. At the same time, it can dry quickly after dispensing, without the need to dry and solidify the glue at the dispensing point separately, and at the same time, it prevents the problems of insufficient glue and glue solidification.
