Description

Technical Field

[0001] The utility model relates to the technical field of production jigs, in particular to a glue dispensing jig for circuit board production. Background Art

[0002] Glue dispensing is a widely used process that involves applying, encapsulating, or dripping electronic glue, oil, or other liquids onto products to allow them to be adhered, encapsulated, insulated, fixed, and have a smooth surface. Glue dispensing is performed on circuit boards as needed during the production process.

[0003] Chinese patent application No. 2020218136308 discloses a glue dispensing cover plate jig, including a positioning jig and a pressed steel sheet, a cover plate steel sheet for preventing glue splashing is arranged above the pressed steel sheet, and glue dispensing holes for glue dispensing are equidistantly arranged on the cover plate steel sheet, and positioning columns are rotatably connected at the four corners of the top of the positioning jig, and a positioning structure for positioning the pressed steel sheet and the cover plate steel sheet is arranged on the positioning column. The setting of the cover plate steel sheet can avoid the problem of scattered glue spraying caused by the glue sprayer during the glue dispensing process. The cooperation of the rotating positioning column and the positioning structure ensures that the pressed steel sheet and the cover plate steel sheet are stable left and right and up and down after being bonded, and there will be no obvious gap between the pressed steel sheet and the cover plate steel sheet in a stable state, thereby avoiding the problem of glue seepage.

[0004] The above-mentioned dispensing cover plate jig can position a circuit board of a fixed size during production. However, the dispensing cover plate jig cannot be adaptively adjusted according to the specific size of the circuit board, resulting in narrow applicability and inconvenience in the use of the device.

[0034] In this embodiment, the circuit board is placed on the flip plate 104, and the rotating head a214 is rotated to drive the screw a212 to rotate. According to the principle of thread transmission, the two clamping blocks a213 are driven to clamp the circuit board from the X direction; the rotating head b224 is rotated to drive the screw b222 to rotate. According to the principle of thread transmission, the two clamping blocks b223 are driven to clamp the circuit board from the Y direction, and the circuit board is positioned on the flip plate 104. Circuit boards of different sizes can be positioned and fixed, thereby expanding the scope of application of the device;

[0035] like Figure 4 As shown, the angle adjustment mechanism 3 includes: an adjustment box 301, which is installed on one side of the connecting frame 101; a rotating rod b302, which is rotatably arranged in the adjustment box 301; a belt 303, which is connected to the rotating rod a103 and the rotating rod b302 through the belt 303; and a driving component 31, which drives the rotating rod b302 to rotate.

[0039] Embodiment 2

[0040] like Figure 5 and Figure 6 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0041] like Figure 5 and Figure 6 As shown, this embodiment includes an auxiliary mechanism 4, which is convenient for moving the circuit board. The auxiliary mechanism 4 includes: a pipeline 401; a connecting column 402, which is installed at one end of the pipeline 401; an air source device, which is connected to the other end of the pipeline 401; an adsorption block 404, which is installed on the connecting column 402, and a vent 405 is opened in the adsorption block 404, which is connected to the pipeline 401.

[0042] In this embodiment, when the circuit board needs to be moved, the end of the adsorption block 404 of the connecting column 402 is manually brought into contact with the circuit board, and the air source device introduces negative pressure into the pipeline 401, thereby adsorbing the circuit board on the connecting column 402 under negative pressure, which makes it easier to move the circuit board.

[0043] It should be noted that: because the four sides of the circuit board are relatively sharp, if it is carried by hand, the circuit board is easy to cut the hands. Therefore, it is necessary to carry the circuit board through the connecting column 402 to prevent cutting the hands. In addition, after the glue is applied to the circuit board, the gas source equipment introduces positive pressure into the pipeline 401, and the gas is ejected through the vent 405. At this time, the connecting column 402 is held and driven to face the glue application point. The gas ejected from the vent 405 can accelerate the drying of the colloid.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
