Description

Technical Field

[0001] The present invention relates to the technical field of circuit board packaging, and in particular to a power supply circuit board automatic testing and packaging device and a method thereof. Background Art

[0002] The power supply circuit board needs to be tested before and after packaging to promptly detect problems such as cold solder joints, short circuits, bubbles in the packaging materials, and component offsets that may exist in the circuit board. At the same time, to ensure the performance of the circuit board, the electrical performance and heat dissipation of the circuit board need to be tested to improve the product yield. For the purpose of protecting the circuit board hardware, some circuit boards will be packaged immediately after testing.

[0003] For example, Chinese patent CN115343597B discloses a packaging test device for circuit boards. The device uses a spiral guide rail and an eccentric wheel to flip the circuit board, thereby facilitating double-sided testing of the circuit board; an infrared temperature probe board continuously monitors the temperature of both sides of the circuit board.

[0004] However, the power circuit board needs to undergo different tests in sequence before packaging, and the required equipment is different. It is difficult for the equipment to perform different tests continuously; it is difficult to automatically sort the circuit boards when testing on the conveyor line; and when the circuit board undergoes multiple continuous tests, if the previous test fails, the subsequent test will be left empty for a round; it is difficult to automatically fill in the position on the conveyor line, which affects the detection efficiency.

[0005] Based on this, the present invention designs a power supply circuit board automatic testing and packaging device and method thereof to solve the above problems. Summary of the Invention

[0013] Furthermore, the conveying mechanism also includes a positioning mechanism and a limiting structure. A plurality of limiting structures for limiting the limiting support structure are installed on the lower side of the feeding conveyor line 1, the transfer conveyor line and the feeding conveyor line 2 on the frame; the positioning mechanisms are symmetrically installed on both sides of the feeding conveyor line 1.

[0014] Furthermore, the positioning mechanism includes a positioning cylinder, a positioning baffle and a limit frame. The positioning cylinder is fixedly mounted on the frame. The output end of the positioning cylinder is fixedly mounted with a positioning baffle. The limit frame is fixedly mounted on the frame. The positioning baffle is slidingly connected to the limit frame.

[0015] Furthermore, the limiting structure includes a limiting support frame and a limiting plate. The limiting support frame is fixedly installed on the frame, and the limiting plates are symmetrically fixedly installed on the inner side of the limiting support frame; limiting grooves are formed between the limiting plates to vertically limit the limiting support structure.

[0016] Furthermore, the flip feeding assembly includes a flip mounting seat, a flip motor, a flip mounting frame and a material picking cylinder linear slide. The flip mounting seat is fixedly mounted on the frame, the flip motor is fixedly mounted on the flip mounting seat, one end of the flip mounting frame is rotatably mounted on the flip mounting seat, and the output end of the flip motor is fixedly connected to the flip mounting frame; the other end of the flip mounting frame is fixedly mounted with a material picking cylinder linear slide, and the movable end of the material picking cylinder linear slide is installed with a material picking structure.

[0017] Furthermore, the continuous material moving assembly includes a multi-stroke cylinder linear slide, a vertical cylinder linear slide and a yield mounting plate.

[0020] In order to better achieve the purpose of the present invention, the present invention also provides a continuous testing and packaging method for an automated testing and packaging device for a power supply circuit board, comprising the following steps:

[0021] Step 1: The feeding conveyor line 1 drives the circuit board to move backward through the limit support structure. The vibration component knocks the limit support structure to make it vibrate, and the blower blows air to the lower side. The visual inspection module and the test component pair inspect the circuit boards in sequence.

[0022] Step 2: Unqualified products are moved back along the feeding conveyor line 1; qualified products are turned over by the flip feeding assembly and the retrieving mechanism. The continuous feeding assembly and the retrieving mechanism drive the circuit boards through the blow nozzle for secondary cleaning, and then transferred to the multi-group test assembly 2 for testing. Finally, the circuit boards are transferred to the transfer conveyor line;

[0023] Step 3: Unqualified products are transported forward by the transfer conveyor line; qualified products are transferred to two sets of test components three for testing via the adjustable material transfer component and the material retrieving mechanism; unqualified products tested by test component three are transferred to the transfer conveyor line, and qualified products are transferred to loading conveyor line two; during this process, the two sets of test components three cooperate with the adjustable material transfer component to dynamically adjust the inspection order: if the first test component three detects an unqualified product during left-to-right inspection and removes it, a new board is added to the left test component three, and a new board is placed on the right test component three for testing. After the two boards are tested, they are swapped and unloaded;

[0024] Step 4: After the circuit board is tested by the test component 1 at the second feeding conveyor line, the unqualified products are directly moved back, and the qualified products are glued and packaged by the dispensing machine and moved back.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: through the cooperation of the loading conveyor line 1, the transfer conveyor line, the loading conveyor line 2 with the flip feeding component, the continuous material moving component, the adjustable material moving component and the material picking structure, the circuit board is continuously inspected, and unqualified products are transported separately to avoid accumulation affecting subsequent inspections; the two groups of test components 3 cooperate with the adjustable material moving component. In the overall continuous inspection, for the items with adjustable inspection order, unqualified products can be removed and replaced in time, so that the two groups of test components 3 can continue to work; for example: when initially inspecting in order from left to right, if the first test component 3 detects unqualified products and removes them, a new board is replaced in the left test component 3, and the second test component 3 is also placed with a new board for inspection; after the two boards are inspected, their positions are exchanged and the materials are unloaded according to the results; compared with the traditional single inspection sequence, this method can avoid the idleness of the test component 3, ensure the inspection efficiency, and solve the problem of low front-end inspection efficiency and mismatch with subsequent dispensing packaging and inspection efficiency.
