Description

Technical Field

[0001] The utility model relates to the technical field of dispensing equipment, in particular to an anti-blocking dispenser. Background Technique

[0002] An automatic dispenser is a professional equipment that replaces manual dispensing and has a wide influence in the industry. In industrial production, dispensing is required in many places, such as integrated circuits, semiconductor packaging, printed circuit boards, etc. Traditional dispensing is achieved by manual operation of workers.

[0003] When replacing the dispensing workpiece of the existing dispenser, the colloid is prone to blockage during static placement. Therefore, some people think of setting a heating mechanism in the dispensing rod to avoid the phenomenon of colloid condensation. For example, the Chinese utility model patent with the publication number CN218048682U specifically discloses an anti-blocking automatic dispenser.

[0004] However, people will find that during the actual use of the above-mentioned dispenser, before dispensing, it is necessary to use a clamping screw to clamp and limit the workpiece. However, the clamping range of the clamping screw is very small, and the workpiece is prone to position deviation during the dispensing operation, greatly reducing its practicability. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-blocking dispenser to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an anti-blocking dispenser, including a workbench, a clamping mechanism and a pressing mechanism. A vertical chute is arranged on the side of the workbench. An electric push rod is arranged inside the vertical chute. The output end of the electric push rod is connected with a lifting slider. An installation plate is fixed on the lifting slider. A track is opened in the middle of the installation plate. A dispensing slider is slidably connected in the track. A dispensing rod is arranged below the dispensing slider;

[0007] The clamping mechanism includes a longitudinal chute, a bidirectional lead screw, a lead screw slider and a clamping plate. The longitudinal chute is opened in the middle position of the workbench. The bidirectional lead screw is arranged inside the longitudinal chute and is parallel to the longitudinal chute. One end of the bidirectional lead screw is rotatably connected in the longitudinal chute. The other end of the bidirectional lead screw penetrates the workbench and is connected with a knob. Two lead screw sliders are symmetrically threadedly connected on the bidirectional lead screw. A clamping plate is fixed on each lead screw slider; By rotating the bidirectional lead screw to drive the lead screw sliders to move towards each other, the workpiece is clamped by using the clamping plate;

[0008] The pressing mechanism is arranged at a position close to the side below the mounting plate. The pressing mechanism includes a telescopic rod, a pressing plate and a spring. The telescopic rod is fixed on the mounting plate, the pressing plate is fixed at the end of the telescopic rod, the spring is sleeved outside the telescopic rod, and both ends of the spring are connected to the pressing plate and the mounting plate respectively; when the mounting plate is driven by an electric push rod to descend, the pressing plate contacts the workpiece first, and the mounting plate continues to descend, compressing the spring and the telescopic rod, and using the elastic force of the spring to press the workpiece tightly until the dispensing rod contacts the workpiece for dispensing.

[0009] Preferably, a driving motor is arranged above the dispensing slider. A rotating shaft is arranged on the driving shaft of the driving motor. The rotating shaft passes through the dispensing slider and is inserted into the dispensing rod with a heating rod arranged therein. A plurality of convex rods are arranged on the outer wall of the heating rod. The driving motor drives the rotating shaft and the heating rod to rotate, and the convex rods are used to stir the colloid. By heating the colloid with the heating rod, the phenomenon of colloid condensation is avoided.

[0010] Preferably, a steel ball is arranged at the end of the dispensing rod. The steel ball is used to block the dispensing port of the dispensing rod. When the dispensing rod contacts the workpiece, the steel ball can be pushed into the dispensing rod under the action of an external force for discharging. The colloid flows out, and then the workpiece can be dispensed; when the external force is removed, the steel ball moves downward in the dispensing rod under the action of gravity to block the dispensing head.

[0011] Preferably, rubber pads are arranged on both the clamping plate and the pressing plate. The rubber pads are mainly arranged to avoid hard contact between the clamping plate and the pressing plate and the workpiece, resulting in damage to the workpiece.

[0012] Preferably, the lead screw slider and the longitudinal chute, and the lifting slider and the vertical chute are respectively connected by sliding.

[0013] Preferably, reinforcing ribs are arranged on the side of the vertical chute to improve the stability of the vertical chute.

The longitudinal chute 7 is opened at the middle position of the workbench 1. The bidirectional lead screw 8 is arranged inside the longitudinal chute 7 and is parallel to the longitudinal chute 7. One end of the bidirectional lead screw 8 is rotatably connected inside the longitudinal chute 7, and the other end of the bidirectional lead screw 8 penetrates through the workbench 1 and is connected with a knob 11. Two lead screw sliders 9 are symmetrically threadedly connected to the bidirectional lead screw 8, and a clamping plate 10 is fixed on each lead screw slider 9. By rotating the bidirectional lead screw 8, the lead screw sliders 9 are driven to move towards each other, and the workpiece is clamped by using the clamping plates 10.

[0025] Further, the pressing mechanism is arranged at a position close to the side below the mounting plate 5. The pressing mechanism includes a telescopic rod 12, a pressing plate 13, and a spring 14. The telescopic rod 12 is fixed on the mounting plate 5, the pressing plate 13 is fixed at the end of the telescopic rod 12, the spring 14 is sleeved outside the telescopic rod 12, and both ends of the spring 14 are respectively connected with the pressing plate 13 and the mounting plate 5. When the mounting plate 5 is driven by the electric push rod 3 to descend, the pressing plate 13 contacts the workpiece first. As the mounting plate 5 continues to descend, the spring 14 and the telescopic rod 12 are compressed, and the workpiece is pressed by the elastic force of the spring 14 until the dispensing rod 15 contacts the workpiece for dispensing.

[0026] Further, a driving motor 17 is arranged above the dispensing slider 16. A rotating shaft 18 is arranged on the driving shaft of the driving motor 17.

Then start the electric push rod 3 to drive the mounting plate 5 to descend, and the mounting plate 5 drives the pressing mechanism and the dispensing rod 15 to descend. When the pressing plate 13 on the pressing mechanism contacts the workpiece, the mounting plate 5 continues to descend and compresses the spring 14 and the telescopic rod 12, so that the spring 14 and the telescopic rod 12 contract, and the pressing plate 13 is pressed on the workpiece by the tension of the spring 14. When the steel ball 21 at the end of the dispensing rod 15 contacts the workpiece, the steel ball 21 retracts into the dispensing rod 15 to dispense glue, so as to perform glue dispensing treatment on the workpiece; during the process, start the drive motor 17, use the drive motor 17 to drive the rotating shaft 18 to rotate, use the rotating shaft 18 to drive the heating rod 19 to rotate, use the convex rod 20 on the heating rod 19 to stir the colloid, and at the same time connect the power supply of the heating rod 19, use the heating rod 19 to heat the colloid, thus effectively avoiding the phenomenon of condensation on the heating rod 19 and improving the practicability of the device.
