Description

Technical Field

[0001] This utility model belongs to the technical field of power strip testing equipment, specifically relating to a power strip welding defect detection device. Background Technology

[0002] A power strip is a multi-socket socket with a cord. Its structure includes a circuit board, copper sheets soldered onto the circuit board, a front cover, and a base cover. In the production process of the power strip, the front cover and base cover are injection molded separately, and then the circuit board is assembled into the base cover. CCD inspection equipment is used to detect defects in the copper sheet soldering.

[0003] In existing CCD inspection equipment, the power strip is moved to the area below the inspection camera via a conveyor belt. Considering that the inspection camera needs the power strip to be in a stable state during the image capture process, a conveyor belt of corresponding width is required for power strips of different widths to avoid the power strips being placed at an angle.

[0004] Furthermore, detecting copper sheet welding defects in power strips requires copper sheet manipulation, as illustrated by the spring sheet manipulation mechanism disclosed in patent CN217371013U after welding a loose weld. However, power strips have two rows of copper sheets. Manipulating only one row at a time reduces the efficiency of the CCD inspection equipment. Current CCD inspection equipment uses two sets of fixed-spaced manipulation structures, with the spacing equal to the spacing between the two rows of copper sheets, to simultaneously manipulate both rows. However, the spacing between the two rows of copper sheets varies in different power strip sizes. This means that for each type of power strip being inspected, the CCD inspection equipment needs to replace both the conveying and manipulation structures, resulting in wasted costs.

Main channel 1 conveys the power strip along the X direction until it is stopped by the blocking device. It then remains at the first inspection station, triggering the sensor located at the first inspection station. The sensor transmits information to the control system, which sends an operating command to the side push device 5 and the first photographic inspection device 4. The side push device 5 lifts the power strip upward and clamps it in place. The first photographic inspection device 4 takes a picture of the inside of the power strip and checks for dirt or damage. Power strips with dirt or damage are directly transferred to the NG product discharge station. Power strips without dirt or damage are transferred by the side push device 5 to the second inspection station. The copper strip pushing device moves the copper strip of the power strip in the forward and / or reverse direction. The second photographic inspection device 7 takes a picture of the copper strip welding position and checks for whether the welding is firm. Power strips that are not firmly welded are transferred to the NG product discharge station. The pushing device 9 pushes both the dirty and damaged power strips and the power strips that are not firmly welded into the NG product receiving box 8.

The output end of the lifting cylinder 64 is fixedly connected to the platform 61. The lifting cylinder 64 is used to push the platform 61 to move along the Z-axis linear guide, adjusting the vertical distance between the platform 61 and the connector. Platform 61 has a rectangular operating hole in the X-direction. The operating hole has a first long side and a second long side that are arranged opposite to each other.

[0044] The method of using the power strip welding defect detection device in this embodiment includes the following steps:

[0045] S1: The power strip enters the main channel 1 from the previous machine. The main channel 1 transports the power strip along the X direction until the power strip is stopped by the pin 3. The lifting component lifts the power strip upward, and then the side pushing component pushes the power strip to clamp it. The first photographic detection device 4 takes an internal photograph to check whether there are stains, residues and particles inside the power strip.

[0046] S2: The camera of the second photo detection device 7 is moved to the position to prepare for taking pictures in advance. The base 52 moves along the X-direction rail 51 until the clamped plug moves to the bottom of the platform 61. Then the toothed pawl moves the copper strip, and at the same time the second photo detection device 7 takes pictures to check whether the copper strip is firmly welded. The toothed pawl then moves the copper strip in the opposite direction and takes pictures again to check whether the copper strip is firmly welded. The NG product enters the NG product discharge station and is stopped, lifted and pushed to the side to remove the waste.

[0047] S3: The signal indicating whether the weld is secure is transmitted to the control system, i.e., the PLC. Qualified products flow directly into the next machine. NG products flow into the NG product discharge station. The side push device 5 pushes the NG products to the NG product receiving box 8 and then resets.
