Description

Technical Field

[0001] This utility model relates to the technical field of circuit board processing equipment, specifically to a circuit board manufacturing adhesive dispensing device. Background Technology

[0002] A circuit board is composed of integrated circuits, quartz oscillators, trimmer capacitors, and printed circuit boards. Circuit boards are also known as ceramic circuit boards, alumina ceramic circuit boards, and aluminum nitride ceramic circuit boards. The production and processing of circuit boards involves many steps, one of which is dispensing. Currently, existing dispensing equipment typically involves placing the circuit board on a workbench and then flexibly controlling the dispensing head to apply adhesive to various locations on the circuit board.

[0003] It is easy to see that existing dispensing equipment has the following shortcomings:

[0004] The circuit board is simply placed on the workbench without being fixed in place by a special positioning fixture. This makes it easy for the circuit board to shift position during dispensing, resulting in inaccurate dispensing and affecting the quality of the final product. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a circuit board manufacturing dispensing device, which can firmly position and fix the circuit board placed on the workbench during use, and then perform dispensing operation on the circuit board in a stable and accurate manner.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0007] A circuit board manufacturing dispensing apparatus, comprising:

[0008] The workbench surface;

[0009] The system comprises an X-axis translation drive mechanism, a Y-axis translation drive mechanism, a Z-axis translation drive mechanism, and a dispensing head; the X-axis translation drive mechanism is mounted on the worktable, the Y-axis translation drive mechanism is driven by the X-axis translation drive mechanism to translate along the X-axis, the Z-axis translation drive mechanism is driven by the Y-axis translation drive mechanism to translate along the Y-axis, and the dispensing head is driven by the Z-axis translation drive mechanism to move up and down along the Z-axis.

[0010] The fixture is set on the worktable and corresponds to the dispensing head.

[0011] As an improvement, the X-axis translation drive mechanism includes a slide channel, a motor, a lead screw, and a movable seat. The two ends of the slide channel are fixed to the platform via support plates. The lead screw is rotatably connected to the inner side of the slide channel, and one end extends to the outer side of the slide channel, where it is driven by the motor fixed to the end of the slide channel. The movable seat slides within the slide channel and is also threaded onto the lead screw. This facilitates the driving of the dispensing head in the X-axis translational movement.

[0012] As an improvement, the Y-axis translation drive mechanism has the same structure as the X-axis translation drive mechanism, and after being set along the Y-axis, the slide of the Y-axis translation drive mechanism is fixed to the lower side of the movable seat of the X-axis translation drive mechanism. This facilitates driving the dispensing head to translate in the Y-axis direction.

[0013] As an improvement, the Z-axis translation drive mechanism includes an electric cylinder, the end of which is mounted and fixed on a movable seat on the Y-axis translation drive mechanism, and a dispensing head is mounted and fixed on the piston shaft end. This facilitates driving the dispensing head to move up and down in the Z-axis.

[0014] As an improvement, the fixture includes a bidirectional threaded rod with handwheels at both ends, a nut sleeve, a connecting rod, a slider, and a clamping plate. A bearing seat fixed to the underside of the table is rotatably sleeved at the middle of the bidirectional threaded rod. A pair of nut sleeves are mirror-shaped and threaded onto the two threaded sections of the bidirectional threaded rod. Connecting rods are hinged to the front and rear sides of the nut sleeves, and the other end of each connecting rod is rotatably connected to a slider. A strip-shaped groove is pre-drilled on the worktable surface corresponding to each slider. The slider slides within the strip-shaped groove, and a clamping plate is fixed to the top surface. The clamping plate is an L-shaped plate with a triangular plate structure formed on its bottom surface. The circuit board is clamped and fixed between the clamping plates. This facilitates the positioning and fixing of the circuit board to be glued.

[0015] It is worth mentioning that many of the motors, electric cylinders, and dispensing heads in this technical solution are existing devices that are common knowledge, and their use and control methods are all existing technologies.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] 1. When in use, this new invention can flexibly control the dispensing head to move in the X, Y and Z directions by coordinating the X-axis translation drive mechanism, Y-axis translation drive mechanism and Z-axis translation drive mechanism, thereby enabling flexible dispensing operations on the circuit board on the worktable.

[0018] 2. This new invention, through the design of the clamp, can conveniently clamp and fix the circuit board placed on the worktable, and then the dispensing operation can be carried out stably, and the dispensing position deviation is not likely to occur. Attached Figure Description

The middle part of the bidirectional threaded rod 10 is rotatably sleeved with a bearing seat fixed to the lower side of the table 1.
