[0002] The main purpose of electronic component placement is to mount electronic components onto a printed circuit board (PCB), complete soldering through a series of process flows, and ultimately assemble them into a complete electronic device or system.

[0003] At present, in the existing technology, for example, the Chinese patent with the announcement number CN221575956U discloses an electronic component patch device, which drives the rotating disk to rotate through the output end of the servo motor to achieve the flipping effect, and clamps the circuit board in the clamping seat through the manual sliding movable block. However, on the one hand, the device lacks a device to support the circuit board during patching to ensure the welding quality and the flatness of the PCB, and avoid printing difficulties, quality risks and other problems. On the other hand, when clamping the circuit board, it is necessary to clamp the left and right sides and the top and bottom of the circuit board separately and use bolts to clamp it. In actual operation, installation and uninstallation require a lot of time, which reduces work efficiency.

[0004] Therefore, the present invention provides an electronic component patch device to solve the above problems. Utility Model Content

[0020] 1. This electronic component patch device, by pressing the push plate, causes the baffle and the round rod to move the rubber plate downward. When the pressure is released, the spring between the push plate and the top of the U-shaped clamping plate rebounds, causing the rubber plate to move upward, clamping the placed circuit board up and down. The circuit board is clamped left and right through the operation of the bidirectional screw and the left and right first sliders, realizing free and fast clamping when patching electronic components, saving time.

[0021] 2. This electronic component patch device starts the electric slide rail, so that the electric slider drives the support plate to move upward.

Then, when the electronic component is flipped, the electric slider drives the support plate to move downward. The repeated operation provides support for the electronic component patch, ensuring the quality of welding. BRIEF DESCRIPTION OF THE DRAWINGS
