Description

Technical Field

[0001] This utility model relates to the field of PCB board welding equipment technology, and in particular to a preheating air jet structure for a PCB board soldering machine. Background Technology

[0002] The control panel is a component of the instrument and equipment. The control panel is composed of a PCB board. Soldering is an indispensable step in the manufacturing process of the PCB board, and its quality directly affects the electrical performance and reliability of the PCB board.

[0003] Before soldering, PCB boards need to be heated and then flux is sprayed to ensure high-quality soldering. Currently, these two processes require separate equipment components, resulting in a large overall size and space requirement for the soldering machine.

[0004] This application provides a preheating air jet structure for a PCB board soldering machine to solve the above-mentioned problems. Utility Model Content

[0005] Based on the above situation, the main purpose of this utility model is to provide a preheating air spray structure for a PCB board soldering machine, so as to solve the problem that the current equipment requires two separate equipment components to work for the two processes of heating and spraying flux, resulting in a large overall size of the soldering machine and a large space occupation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A preheating air jet structure for a PCB soldering machine includes a frame, a sliding plate, a heating and blowing assembly, and a dispensing mechanism;

[0008] A transverse beam is fixed on one side of the frame, and a vertical beam is slidably connected to one side of the transverse beam in the horizontal direction. The sliding plate is slidably connected to the vertical beam in the vertical direction.

[0009] Both the heating and blowing assembly and the dispensing mechanism are fixed to the sliding plate.

[0010] Preferably, the frame includes two vertical plates and a horizontal plate, and the horizontal beam is fixed to the horizontal plate.

[0011] Preferably, it also includes a total traverse mechanism;

[0012] The overall transverse movement mechanism includes a long beam, which is fixed to the transverse plate and is capable of sliding in the horizontal direction.

[0013] Preferably, it also includes a main lifting mechanism;

[0014] A connecting plate is provided on one side of the long beam. The connecting plate is slidably connected to the long beam in the horizontal direction. The main lifting mechanism includes a mounting beam. The connecting plate is fixed to the mounting beam. A lifting plate is slidably connected to the side of the mounting beam away from the connecting plate in the vertical direction.

[0015] Preferably, the sliding plate includes a first planar portion and a second planar portion, the second planar portion is fixed to one side of the first planar portion, the vertical side length of the first planar portion is D1, and the vertical side length of the second planar portion is D2, wherein D1 < D2.

[0016] Preferably, there are two of each of the sliding plate, the heating and blowing assembly, and the dispensing mechanism.

[0017] The beneficial effects of this invention are as follows: During operation, the air outlet of the heating and blowing assembly can blow out hot air to preheat the PCB board. After preheating, the dispensing mechanism can discharge flux at the soldering position for subsequent soldering. In this application, both the heating and blowing assembly and the dispensing mechanism are mounted on the same sliding plate, allowing them to start sequentially in the shortest possible time, improving the flux spraying effect. Furthermore, they do not require separate external mounting for fixation, reducing the overall size of the soldering machine and minimizing space requirements.

[0028] Reference Figure 1-3 This utility model provides a preheating air jet structure for a PCB soldering machine, used for heating and applying flux to the PCB board before soldering. It includes a frame 1, a sliding plate 2, a heating and blowing assembly 3, a dispensing mechanism 4, a main horizontal movement mechanism 5, and a main lifting mechanism 6. The sliding plate 2 is mounted on the frame 1, and the heating and blowing assembly 3 and the dispensing mechanism 4 are both mounted on the sliding plate 2. The main lifting mechanism 6 is slidably mounted vertically on an external body (not shown in the figure). The main horizontal movement mechanism 5 is slidably connected to the main lifting mechanism 6 in the horizontal direction, and the main horizontal movement mechanism 5 is fixed to the frame 1. This allows the main lifting mechanism 6 to drive the main horizontal movement mechanism 5 and the frame 1 to move vertically as a whole, and the main horizontal movement mechanism 5 can drive the frame 1 to move horizontally relative to the main lifting mechanism 6, thereby significantly adjusting the positions of the heating and blowing assembly 3 and the dispensing mechanism 4.

[0029] The frame 1 includes two upright plates 11 and a transverse plate 12. The transverse plate 12 is fixed between the two upright plates 11. Two transverse beams 13 are fixed to one side of the transverse plate 12. A vertical beam 14 is slidably connected to one side of the transverse beam 13 in the horizontal direction. A sliding plate 2 is slidably connected to the vertical beam 14 in the vertical direction. Two heating and blowing assemblies 3 and two dispensing mechanisms 4 are provided. The two heating and blowing assemblies 3 and the dispensing mechanism 4 are respectively fixed on the sliding plate 2. The air outlet of the heating and blowing assembly 3 and the discharge port of the dispensing mechanism 4 are both downward. The vertical beam 14 can slide horizontally on the transverse beam 13, and the sliding plate 2 can slide vertically on the vertical beam, thereby adjusting the position of the heating and blowing assembly 3 and the dispensing mechanism 4. It should be noted that the structures driving the vertical beam 14 and the sliding plate 2 can both be a combination of a slider, a lead screw, and a motor. Specifically, a slider is fixed to the vertical beam 14 and slidably connected to the horizontal beam 13. A lead screw is rotatably connected inside the horizontal beam 13. The motor can drive the lead screw to rotate, and the lead screw is threadedly connected to the slider, thus causing the slider to slide, thereby moving the vertical beam 14. Similarly, the sliding plate 2 can also use this structure for vertical sliding. This sliding structure is existing technology and will not be illustrated or described further in this application. During operation, the air outlet of the heating and blowing assembly 3 can blow hot air to preheat the PCB board. After preheating, the dispensing mechanism 4 can discharge flux at the soldering position for subsequent soldering. In this application, the heating and blowing assembly 3 and the dispensing mechanism 4 are both mounted on the same sliding plate 2, allowing them to start sequentially in the shortest possible time, improving the flux spraying effect. Furthermore, they do not require separate external mounting, reducing the overall size of the soldering machine and minimizing space requirements.

[0030] In one embodiment, the main transverse movement mechanism 5 includes a long beam 51, which is fixed to the transverse plate 12. The long beam 51 and the main lifting mechanism 6 can slide horizontally, thereby driving the frame 1, the heating and blowing assembly 3, and the dispensing mechanism 4 to move over a wide range. Furthermore, a connecting plate 52 is provided on one side of the long beam 51, which slides horizontally to the long beam 51. The main lifting structure includes a mounting beam 61, which is vertically arranged. One side of the mounting beam 61 is fixed to the connecting plate 52, and the side of the mounting beam 61 away from the connecting plate 52 is vertically connected to a lifting plate 62. The lifting plate 62 is fixed to the external body. The mounting beam 61 can move up and down relative to the lifting plate 62, thereby driving the connecting plate 52 to move up and down. The up and down movement of the connecting plate 52 can drive the long beam 51 to move up and down. The long beam 51 can also slide horizontally relative to the connecting plate 52, allowing the entire frame to slide up and down and horizontally over a wide range. Furthermore, the lateral movement of the vertical beam and the longitudinal movement of the sliding plate 2 allow for precise adjustment of the air outlet of the heating and blowing assembly 3 and the discharge port of the dispensing mechanism 4, resulting in greater applicability. It should be noted that the sliding connection structure between the connecting plate 52 and the long beam 51 and the mounting beam 61 and the lifting plate 62 is similar to the aforementioned sliding structure. A lead screw is installed within the long beam 51 and the mounting beam 61. The movement of the connecting plate 52 on the long beam 51 and the mounting beam 61 is achieved through the threaded engagement of the lead screw and the slider fixed to the connecting plate 52 and the lifting plate 62.

[0031] In one embodiment, the sliding plate 2 includes a first flat portion 21 and a second flat portion 22. The second flat portion 22 is fixed to one side of the first flat portion 21. The heating and blowing assembly 3 is fixed to the first flat portion 21, and the dispensing mechanism 4 is fixed to the second flat portion 22. The vertical side length of the first flat portion 21 is D1, and the vertical side length of the second flat portion 22 is D2, where D1 < D2. This application adjusts the shape of the sliding plate 2 to accommodate the dispensing mechanism 4, providing a longer second flat portion 22. This allows the shorter dispensing mechanism 4 to be positioned downwards, making the air outlet of the heating and blowing assembly 3 and the discharge port of the dispensing mechanism 4 very close in height.

[0032] The implementation principle of this utility model is as follows: During operation, the air outlet of the heating and blowing assembly 3 blows hot air to preheat the PCB board. After preheating, the dispensing mechanism 4 can discharge flux at the soldering position for subsequent soldering. In this application, both the heating and blowing assembly 3 and the dispensing mechanism 4 are mounted on the same sliding plate 2, allowing them to be activated sequentially on the PCB board in the shortest possible time, improving the flux spraying effect. Furthermore, they do not require separate external mounting for fixation, reducing the overall size of the soldering machine and minimizing space requirements.

[0033] Those skilled in the art will understand that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0034] It should be understood that the above-described embodiments are merely exemplary and not restrictive. Without departing from the basic principles of this utility model, any obvious or equivalent modifications or substitutions that those skilled in the art can make regarding the above details will be included within the scope of the claims of this utility model.
