[0026] The silver paste-based printed circuit board described in this embodiment drives the components to be loaded to move up and down through the guide drive mechanism 200 and the supporting mechanism 100. During this process, when the first detector 310 detects that the components to be loaded are supported on the hopper platform 110, the guide drive mechanism 200 drives the hopper platform 110 to rise. When the second detector 320 detects that the component on the top has been removed, the guide drive mechanism 200 drives the hopper platform 110 to descend.

Based on this, the present application can adaptively adjust production lines with different production efficiencies, thereby achieving high automation of the loading process. Compared with conventional loading equipment, the present application has significant advantages such as easy operation, practicality and flexibility, wide application range and high loading efficiency.

[0027] See also Figure 1As shown, the hopper platform 110 in this embodiment has a rectangular support surface with a detection point at its center, which is used to support the printed circuit board (PCB) clamp. In this embodiment, to ensure the clamp is stably supported in the center of the hopper platform 110 and the PCB can reach a designated position within the clamp, the support mechanism 100 in this embodiment also includes at least one stop block 120 and at least one hanging brush 130. Each of the at least one stop block 120 and the at least one hanging brush 130 is positioned at the edge of the hopper platform 110 and moves toward or away from the center of the hopper platform 110. Specifically, multiple stop blocks 120 and multiple hanging brushes 130 are provided in this embodiment. The multiple stop blocks 120 and multiple hanging brushes 130 are arranged in a one-to-one correspondence and are evenly spaced along the edge of the hopper platform 110. Specifically, any set of stop blocks 120 and hanging brushes 130 can be horizontally moved using knobs at their bases, thereby circumferentially positioning the clamp and PCB. Furthermore, the carrying mechanism 100 in this embodiment further includes at least one handle 140 and at least one reinforcing plate 150 , and the handle 140 and the reinforcing plate 150 are respectively connected to two sides of the silo platform 110 in the thickness direction.

[0028] See also Figure 2 and Figure 3 As shown, the guide drive mechanism 200 is used to provide driving power and a moving path for the movement of the carrying mechanism 100. The guide drive mechanism 200 includes a mounting backplate 210, a drive assembly 220 and a screw rod 230. The drive assembly 220 is connected to the mounting backplate 210. The drive assembly 220 is connected to the screw rod 230 to drive the screw rod 230 to rotate around its axis. A connecting member 112 is provided on the silo platform 110. The connecting member 112 is threadedly engaged with the screw rod 230 and moves along the extension direction of the screw rod 230. Further, the drive assembly 220 includes a rotary driver 221, a transmission belt 222 and a reducer 223. The reducer 223 is connected to the rotary driver 221.

[0029] See also Figure 1 and Figure 3As shown, the first detector 310 is a tilting photoelectric detector that can detect whether there are components to be transferred on the silo platform 110, thereby cooperating with the first transfer device to realize the loading process of the silo platform 110. The second detector 320 is a through-beam photoelectric detector that can detect whether it has risen to the target position, thereby cooperating with the second transfer device to realize the process of removing components from the silo platform 110. Furthermore, the detection mechanism 300 includes two second detectors 320, which are respectively connected to the top of the guide drive mechanism 200 via a connecting plate 330 and are arranged opposite each other.

Parameters can also be preset through the control system, thereby improving the degree of automation of this equipment.

[0031] The following describes the working process and principle of the adjustable feeding device based on silver paste printed circuit board in this embodiment:

[0032] First, when the first detector 310 detects that the silo platform 110 is empty, the first conveyor device prevents the component to be loaded from entering the silo platform 110 and adjusts the component's position using the stop block 120 and the hanging brush 130. The silo platform 110 then rises until the second detector 320 detects that the silo platform 110 has reached its highest position, causing it to stop and the second conveyor device to transfer the component, thus completing the component loading process.

[0033] Example 2

[0034] This embodiment provides an adjustable feeding system based on a silver paste printed circuit board, which includes the above-mentioned adjustable feeding device based on a silver paste printed circuit board.

[0035] In summary, the adjustable loading device and system based on silver paste printed circuit boards described in the present invention drives the components to be loaded to move up and down through the guide drive mechanism 200 and the supporting mechanism 100. During this process, when the first detector 310 detects that the component to be loaded is supported on the hopper platform 110, the guide drive mechanism 200 drives the hopper platform 110 to rise. When the second detector 320 detects that the component on the top has been removed, the guide drive mechanism 200 drives the hopper platform 110 to descend. The reciprocating process of the above process can achieve uninterrupted loading of components. Based on this, the present application can adaptively adjust production lines with different production efficiencies, thereby achieving high automation of the loading process. Compared with conventional loading equipment, the present application has significant advantages such as easy operation, practicality and flexibility, wide application range and high loading efficiency.
