[0019] Please see Figure 1 and Figure 2 A dispensing assembly device includes a base 1, on which are arranged: a conveying track 2, a stepping transfer mechanism 3, a dispensing mechanism 4, a pressure assembly mechanism 5, a linear pushing mechanism 6, a receiving mechanism 7, a camera 8, and a vibrating feeding mechanism 9.

[0020] like Figure 3 As shown, the conveyor track 2 is divided into a feeding section 21, a dispensing section 22, an assembly section 23, and an unloading section 24 along its extension direction. The feeding section 21 receives parts to be assembled, the dispensing section 22 dispenses adhesive onto the parts, the assembly section 23 pressurizes the dispensed parts to a second assembly part, and the unloading section 24 outputs the assembled workpiece. A guide gap 25 is provided along the axial direction of the conveyor track 2. Two assembly pins of the part to be assembled pass through this guide gap 25 side-by-side, suspending the part body above the conveyor track 2, with the ends of the assembly pins below the upper surface of the conveyor track 2.

[0021] like Figure 4 As shown, the stepping transfer mechanism 3 is used to drive the parts on the conveying track 2 to move stepwise between sections. It includes: a guide track 31, a first-stage lead screw pair 32, a second-stage lead screw pair 33, a moving slider 34, a slider base 35, and workpiece forks 36.

[0022] Each workpiece shift fork 36 has a positioning groove 361 at its end. The contour of the positioning groove 361 is adapted to the shape of the part to be assembled, and is used to engage and push the part to be assembled step by step. There are two positioning grooves 361 on the workpiece shift fork 36, which are arranged along the conveying direction of the part to be assembled. The contour of each positioning groove 361 is a semi-circular structure. The radius of curvature of the semi-circular structure is equal to the radius of the circular assembly part of the part to be assembled, forming a semi-enclosed positioning constraint.

[0025] During operation, the crank connecting rod assembly 56 drives the rotating block 57 to perform eccentric rotation, causing the second assembly part of the clamping cylinder 58 to move vertically downward and align with the part to be assembled on the conveying track 2. When the two parts come into contact, the rotating block 57 continues to press down to generate axial assembly pressure. After the assembly is completed, the clamping cylinder 58 releases the workpiece.

A lifting drive cylinder 68 is provided between the push rod 67 and the slider 66. When the servo motor 65 runs, it drives the push rod 67 to reciprocate linearly along the conveying direction of the unloading section 24, pushing the assembled workpiece out of the conveying track 2.

[0029] like Figure 9 As shown, a receiving mechanism 7 is installed at the discharge end of the conveyor track 2, mainly composed of a transverse guide rail 71, a horizontal synchronization module, and a pallet carrier. The transverse guide rail 71 is perpendicular to the conveyor track 2. The horizontal synchronization module consists of a driving pulley 73 driven by a stepper motor 72, a driven pulley 74, and a horizontal synchronization belt 75 tensioned between them. The horizontal synchronization module structure adopts conventional technology. The pallet carrier slides with the transverse guide rail 71 via a linear slider 76 and is fixedly connected to the working surface of the horizontal synchronization belt 75. Multiple workpiece slots 77 are arranged in a matrix on the pallet carrier, with the opening end of each workpiece slot 77 facing the discharge direction of the conveyor track 2.

[0030] like Figure 1 and Figure 2 As shown, a camera 8 is installed above the assembly section 23 of the conveyor track 2 to collect image information of the parts to be assembled. A vibrating feeding mechanism 9 is provided at the front end of the feeding section 21 of the conveyor track 2 to transport the parts to be assembled onto the feeding section.

[0031] The dispensing and assembly equipment of this utility model adopts a precision feeding and orientation method.

The actuating plate (workpiece fork) of the transfer mechanism pushes the workpiece step by step. The workpiece is dispensed and aligned and pressed in the dispensing section and the assembly section respectively. The workpiece is pushed out at a uniform speed to the tray carrier of the receiving mechanism in the unloading section.
