Description

Technical Field

[0001] The utility model belongs to the technical field of circuit boards, and in particular relates to a control board electronic component patch unloading mechanism. Background Art

[0002] The exposed electronic components of the circuit board substrate are treated with anti-oxidation materials and then screen-printed before packaging and storage. During the electronic component patch operation, the circuit board is transferred to the automatic optical detector through the belt transmission mechanism again to detect whether there are any abnormalities on the surface of the circuit board. The circuit board is then unloaded from the conveyor belt to enter the next process. The circuit board is placed in a tray and solder paste is applied through a perforated plate. The electronic component patch machine is then used to automatically place the electronic components in the corresponding soldering position. The tray and the patched circuit board are placed in a PCB oven for heating and curing, so that the electronic components are soldered and fixed to the circuit board. For circuit boards with large volume and weight, operators cannot complete the handling operation of the circuit boards alone. When the circuit boards are unpacked and loaded onto the belt transmission mechanism, the unassembled circuit boards are placed on the splitting table by a robot. After the operator removes the outer packaging of the circuit boards, the circuit boards are pushed and loaded onto the belt transmission mechanism by an electric push rod mechanism or a telescopic cylinder pushing mechanism. After the circuit boards are optically inspected, they still need to be clamped and unloaded into the tray by a robot. Setting up multiple automated loading and unloading robots not only increases the production cost, but also places high requirements on the working area of ​​the workshop. A single person cannot carry the circuit boards loaded onto the belt transmission mechanism to the tray, which has the disadvantages of high production cost and low production operation efficiency. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a mechanism which can unload the circuit boards received on the belt transmission mechanism onto the corresponding ramp through a rotatable unloading crossbeam.

The cylinder seat is fixedly installed on the inner side of the base, the cylinder body of the telescopic cylinder is hingedly installed on the cylinder seat, and the push plate is fixedly installed on the inner side. The bottom of the unloading beam is provided with a T-shaped groove, and a T-shaped slider is slidably installed in the T-shaped groove. The top of the piston rod of the telescopic cylinder is hinged to the T-shaped slider, and the lower end of the connecting rod is fixedly installed on the base, and the bottom of the L-shaped plate is fixedly installed on the upper end of the connecting rod.

[0006] Furthermore, the bottom of the L-shaped plate is fixedly mounted on the upper end of the connecting rod by locking with a lock nut.

[0007] Compared with the prior art, the utility model has the following advantages: the unloading mechanism can keep the conveyor belt in a tensioned state through the tension spring and the tension wheel, and when the unloading beam rotates, the tension spring can be adjusted adaptively to avoid slipping.

The tensioning wheel 82 is rotatably installed on the round shaft 81. The upper and lower ends of the tension spring 9 are fixedly connected with the square shaft 8 and the L-shaped plate 6 respectively. The transmission belt 61 is transmission-installed on the first pulley 31, the second pulley 41, and the tensioning wheel 82.

[0013] It also includes a linear slide rail 63 and a slider 83. The two linear slide rails 63 are vertically fixedly installed on the L-shaped plate 6. Both ends of the slider 83 are slidably installed on the linear slide rails 63. The middle part of the slider 83 is fixedly connected to the square shaft 8.
