Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a circuit board processing glue coating mechanism. Background Art

[0002] During the processing of circuit boards, in order to ensure the waterproof and moisture-proof performance of the circuit boards and to increase the connection stability between electrical components on the circuit boards, it is necessary to apply glue at the joints between the electrical components, so as to seal the joints and connecting wires of the electrical components and prevent leakage of the joints and connecting wires.

[0003] The existing circuit board processing and gluing mechanism usually transports the circuit board to the gluing place by conveying, then presses the circuit board down and fixes it by a pressing plate, and then glues it by a laterally movable gluing head. However, during the gluing process, the gluing head can only apply glue in the horizontal direction, and the position of the circuit board is relatively fixed, so the gluing range on the surface of the circuit board is small, and its use is relatively limited. Moreover, after gluing the circuit board, the existing circuit board processing and gluing mechanism needs to transport the circuit board to a drying box for drying by a conveyor belt, which makes the device larger in size, complicated in operation process, and relatively low in gluing efficiency for the circuit board. For this reason, we propose a circuit board processing and gluing mechanism. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a circuit board processing gluing mechanism, including a support seat 1, a mounting frame 2 is fixedly connected to the top of the support seat 1, a first linear module 3 is arranged on the top of the support seat 1, and an operating table 4 is fixedly connected to the top of the movable slide of the first linear module 3, and adjustable fixing rods 5 are symmetrically arranged on the top of the operating table 4, and a circuit board is connected between the two adjustable fixing rods 5.

[0021] It should be noted that the distance between the two adjustable fixing rods 5 on the operating table 4 can be adjusted. The spacing between the two adjustable fixing rods 5 can be adjusted according to the size of the circuit board, so that the two adjustable fixing rods 5 can clamp and fix the two sides of the circuit board to stabilize the position of the circuit board to be glued.

[0022] A second linear module 6 is arranged on the top of the mounting frame 2, and an electric push rod 7 is fixedly installed on the top of the movable slide of the second linear module 6, and the piston rod end of the electric push rod 7 passes through the movable slide and is fixedly connected to a lifting plate 8, and a glue head 9 is fixedly installed on the bottom of the lifting plate 8, and a dust removal and drying component 10 for dust removal and drying the circuit board is arranged on the side wall of the lifting plate 8.

[0023] It should be noted that when the utility model is used, it is only necessary to place the circuit board to be glued on the top of the operating table 4, and then adjust the rotating rod 17 to rotate, so that the bidirectional screw rod 15 rotates, and the two adjustable fixing rods 5 are connected to the screws at both ends of the bidirectional screw rod 15 through the protrusions at the bottom of the two adjustable fixing rods 5, so that the two sides of the circuit board are clamped and fixed. During detection, the glue dispensing head 9 is fixedly installed at the bottom of the lifting plate 8, and the glue dispensing head 9 is connected to the external glue storage box. Before glue dispensing, the hot air blower 11 is controlled to work, and the position to be glued is blown and dusted through the blowing port 14. During glue dispensing, the glue dispensing head 9 can be controlled by the second linear module 6 to move along the mounting frame 2, and the electric push rod 7 works to glue the surface of the circuit board. The first linear module 3 can control the circuit board to move in a direction perpendicular to the second linear module 6, so that glue can be applied to any position on the surface of the circuit board. After the glue dispensing is completed, the hot air blower 11 works, and the glue dispensing position of the circuit board is dried with hot air through the blowing port 14, so that the position after glue dispensing is quickly solidified.

[0024] A horizontal groove is provided on the top of the operating table 4, and a bidirectional screw rod 15 is rotatably connected in the groove. The end of the bidirectional screw rod 15 passes through the operating table 4 and is fixedly connected to a rotating rod 17. The bottom centers of the two adjustable fixed rods 5 are integrally provided with a protrusion, and the two protrusions are symmetrically threadedly connected to the two ends of the bidirectional screw rod 15.

[0025] It should be noted that the rotation of the bidirectional screw rod 15 can be controlled by rotating the rotating rod 17, so that the adjustment of the spacing between the two adjustable fixing rods 5 can be controlled by connecting the bottom protrusions of the two adjustable fixing rods 5 with the threads at both ends of the bidirectional screw rod 15.

[0026] The dust removal and drying component 10 includes a hot air blower 11, a ventilation pipe 12, a branch pipe 13 and an air blowing port 14. The hot air blower 11 is fixedly installed on the top of the lifting plate 8. The air inlet end of the hot air blower 11 is connected to the outside. The air outlet end of the hot air blower 11 is fixedly connected to the ventilation pipe 12, and two branch pipes 13 are formed at the ends of the ventilation pipe 12. The two branch pipes 13 are symmetrically fixedly installed on both sides of the lifting plate 8, and air blowing ports 14 are equidistantly arranged on the outside of the branch pipes 13.

[0027] It should be noted that, through the coordinated arrangement of the hot air blower 11, the ventilation pipe 12, the branch pipe 13 and the blowing port 14, on the one hand, the circuit board surface can be blown and dusted before glue dispensing, and on the other hand, the glue dispensing position can be dried with hot air in time after glue dispensing, so that the glue dispensing position can be quickly solidified, thereby greatly improving the glue dispensing efficiency.

[0028] The air blowing port 14 is in a cone-shaped structure as a whole, and the end of the air blowing port 14 is arranged toward the circuit board.

[0029] It should be noted that the blowing port 14 provided with a conical structure can expand the blowing area of ​​the circuit board, so that the glue point can be quickly dried with hot air to make the glue liquid solidify quickly.

[0030] A horizontal limit groove 16 is symmetrically provided on the top of the operating table 4 and outside the groove. A limit block is symmetrically provided on the bottom of the adjustable fixing rod 5 and is slidably connected in the limit groove 16 .

[0031] It should be noted that when the operating table 4 slides on the support base 1 , the limit block thereon is slidably connected inside the limit groove 16 , so that the operating table 4 can slide in a directional manner on the support base 1 , thereby limiting the movement range of the operating table 4 .

[0032] The adjustable fixing rod 5 is fixedly provided with an anti-skid pad on one side of the circuit board.

[0033] It should be noted that, by providing an anti-skid pad on the side wall of the adjustable fixing rod 5, when the two adjustable fixing rods 5 clamp the two sides of the circuit board, the anti-skid pad on the side wall of the adjustable fixing rod 5 contacts the side wall of the circuit board, thereby increasing the friction between the circuit board and the circuit board, so that the circuit board can be firmly clamped.
