Description

Technical Field

[0001] The utility model belongs to the technical field of dispensing equipment, and particularly relates to a PCB board processing dispensing equipment. Background Art

[0002] A PCB, the Chinese name is printed circuit board, also known as printed wiring board, is an important electronic component, a support for electronic components, and a carrier for electrical interconnection of electronic components. Since it is made by electronic printing technology, it is called a "printed" circuit board. Almost every electronic device, from small electronic watches and calculators to computers, communication electronic devices, and military weapon systems, as long as there are electronic components such as integrated circuits, in order to achieve electrical interconnection between each component, a printed circuit board is required. The circuit board itself is usually composed of several electronic components, and it is necessary to dispense glue on the fixed parts of the electronic components, drop the glue onto the fixed positions of the circuit board, and fix it through the dispensing part and external parts to realize the installation of the electronic components. When the existing dispensing machine is working, during short or long idle periods, the glue will harden. The hardened glue will block the glue outlet, resulting in no glue output when used again. Before dispensing on the PCB board, it needs to be fixed. If not fixed, during the dispensing process, the dispensing trajectory may be affected due to the offset of the PCB board position, thus affecting the subsequent use.

[0003] The Chinese utility model patent with the publication number of CN220295064U discloses a PCB board processing dispensing equipment. When the device is working, first turn on the motor, then the baffle puts the glue stick into the glue grid and rotates the squeezer to make the glue flow into the pointed glue bucket. Then, the driving end of the motor drives the bottom scraping blade structure and the inclined blade rotating shaft to rotate to stir the glue in the glue bucket. During the feeding and dispensing of the glue, it is in a stirring motion, so that the glue will always be in a rotating state when it enters the glue bucket. The glue can be stirred by driving the stirring structure through the motor, so that the glue will not be in a stagnant state, which can prevent the glue from hardening and blocking the glue pipe when not in use. At the same time, start the electric telescopic rod at the bottom of the machine body. When the electric telescopic rod moves, it will drive the beveled cube at the top of the rod to move up and down. When moving, it will also drive the wheel at the bottom end of the guide rod on the hypotenuse of the beveled cube to slide. When sliding, it will drive the push rod to move horizontally, and push the board to the inner wall of the rear end of the working frame for clamping. The left side of the push rod point is driven by the electric push rod to move horizontally in the working frame, and when it moves to the spring column, it is clamped, so that the PCB board can be clamped, thus solving the problem that the PCB board will not shift during dispensing and the dispensing trajectory will not have problems. However, the device still has some other problems. For example, when the device is in use, it lacks a structure for removing air dust, resulting in dust in the air being mixed during the dispensing process, which in turn affects the quality of dispensing.

[0071] This embodiment provides a glue dispensing device for PCB board processing. In addition to including the technical solution of the above embodiment, it also has the following technical features.

[0072] As Figures 1-4 shown, in this embodiment, the fixing mechanism 400 includes:

[0073] The spring 410 is arranged on one side where the two mounting frames 110 are close to each other. One end of the spring 410 is fixedly connected to the mounting frame 110, and the spring 410 is slidably arranged on the upper surface of the workbench 100;

At this time, the buffer blocks 430 on the two fixing plates 420 can protect the PCB board and prevent the PCB board from being damaged.

[0077] This embodiment provides a PCB board processing dispensing device. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0078] As Figures 1-4 shown, in this embodiment, a scraping plate 231 is arranged below the sliding plate 230. The scraping plate 231 is arranged on the side plate of the sliding plate 230 away from the air nozzle 250, and the lowest end of the scraping plate 231 is in sliding contact with the upper surface of the workbench 100.

[0079] In this technical solution, in order to facilitate the cleaning of the excess glue on the workbench 100, a scraping plate 231 is arranged below the sliding plate 230. The scraping plate 231 is arranged on the side plate of the sliding plate 230 away from the air nozzle 250. At the same time, the lower end of the scraping plate 231 is in a state of being attached to the upper surface of the workbench 100. In this way, by changing the position of the slider, the scraping plate 231 can clean the upper surface of the workbench 100 along the direction of the guide rod 220, so as to clean the glue block formed on the upper surface of the workbench 100 and prevent the problem that the uneven surface of the workbench 100 causes the uneven fixing of the PCB board.

[0080] This embodiment provides a PCB board processing dispensing device. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0081] As Figures 1-4 shown, in this embodiment, inclined plates 440 are arranged at both ends of the fixing plate 420, and the inclined plates 440 are arranged toward the side close to the mounting bracket 110.

[0082] In this technical solution, in order to facilitate the cleaning of the upper surface of the workbench 100 by the squeegee 231 and prevent the fixing plate 420 from obstructing the movement of the squeegee 231, inclined plates 440 are provided at both ends of the fixing plate 420. The inclined plates 440 are arranged towards the mounting frame 110 on the same side. In this way, when the squeegee 231 is displaced, it can compress the fixing plates 420 on both sides to a certain distance along the inclined plates 440, thus ensuring that the squeegee 231 can smoothly move from one end of the workbench 100 to the other end.

[0083] This embodiment provides a PCB board processing dispensing device. In addition to including the technical solution of the above embodiment, it also has the following technical features.

In this way, when the air nozzle 250 cleans the workbench 100, the inclined air nozzle 250 can blow the dust and impurities out from one end of the workbench 100, preventing the dust or impurities from accumulating on the workbench 100.
