[0041] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0042] This invention proposes a testing and marking machine for dual in-line packaged power transformers, comprising a body 1 and a feeding mechanism 2, a high-voltage testing component, an electrical testing component, and a laser marking mechanism 7 mounted on the body 1. The high-voltage testing component includes a high-voltage testing mechanism 3 and a first dispensing mechanism 4 connected to the high-voltage testing mechanism 3; the high-voltage testing mechanism 3 is also connected to the feeding mechanism 2. The electrical testing component includes an electrical testing mechanism 5 and a second dispensing mechanism 6 connected to the electrical testing mechanism 5; one end of the electrical testing mechanism 5 is connected to the first dispensing mechanism 4, and the other end is connected to the second dispensing mechanism 6. The laser marking mechanism 7 is connected to the second dispensing mechanism 6, and a receiving mechanism 8 is also connected to the laser marking mechanism 7.

[0043] In this embodiment, the receiving mechanism 8 includes an electrical defect receiving device 82, a high-voltage defect receiving device 81, and a good product receiving device. The good product receiving device is used to collect power transformers that have passed the high-voltage test by the high-voltage testing mechanism 3 and the electrical test by the electrical testing mechanism 5, and have also been marked by the laser marking mechanism 7. The electrical defect receiving device 82 is connected to the second sorting mechanism 6 and collects power transformers that have not passed the electrical test by the electrical testing mechanism 5. The high-voltage defect receiving device 81 is connected to the first sorting mechanism 4 and collects power transformers that have not passed the high-voltage test by the high-voltage testing mechanism 3.

[0044] The first material distribution mechanism 4 is connected to a high-voltage faulty material receiving track 91; the second material distribution mechanism 6 is connected to an electrical faulty material receiving track 92.

[0045] In this embodiment, the high-voltage testing mechanism 3 includes a pressing cylinder 31 and two sets of probe assemblies 32. Each probe assembly 32 includes a probe mounting plate 321, probes 322 mounted on the probe mounting plate 321, and a pushing device 323 that moves the probe mounting plate 321. The pressing cylinder 31 is connected to a pressing plate 33, and a sliding rail 34 is provided at the lower part of the pressing plate 33. The two sets of probe assemblies 32 are respectively located on both sides of the pressing plate 33. A first sliding assembly 35 is provided at the lower part of the probe mounting plate 321. The sliding rail 34 is connected to the conveying rail 9. The pushing device 323 is fixed to the machine body 1 and pushes the probe mounting plate 321 towards the sliding rail 34. A first product positioning detection device is provided on the pressing plate 33. This device detects the position of the power transformer within the sliding rail 34, facilitating contact between the probes 322 and the pins of the power transformer to complete the high-voltage test. A first sliding component 35 is provided at the lower part of each of the two probe mounting plates 321. The first sliding component 35 is used to facilitate the movement of the probe mounting plate 321.

[0046] The working principle of the high-voltage testing mechanism 3 is as follows: the power transformer under test slides into the sliding track 34 at the lower part of the pressing cylinder 31. At this time, the first product positioning device detects the positioning status of the power transformer. After the power transformer is fully positioned, the pressing cylinder 31 presses down the pressing plate 33 and the pushing devices 323 on both sides of the pressing plate 33 push the probe mounting plate 321 to move towards the sliding track 34 in the middle of the pushing device 323, so that the probes 322 on the probe mounting plates 321 on both sides contact the pins on both sides of the power transformer to perform high-voltage testing of the power transformer.

[0047] In this embodiment, both the first dispensing mechanism 4 and the second dispensing mechanism 6 include four dispensing cylinders 41, dispensing devices 42 respectively connected to the four dispensing cylinders 41, and a second sliding assembly 43 disposed below the dispensing device 42. The dispensing device 42 is provided with three material passages 421, and a limiting block 422 is provided between the material passages 421. The limiting block 422 is a rectangular structure with closed sides and an open top. The second sliding assembly 43 is disposed below the dispensing device 42. The second sliding assembly 43 includes a sliding guide rail and a slider disposed on the sliding guide rail and matching the sliding guide rail. The slider is fixedly connected to the dispensing device 42. A baffle 44 is provided on the dispensing device 42, which covers the four dispensing devices 42 and fixes them to the machine body 1. The four dispensing cylinders 41 are connected to the same connecting plate 45, which can fix the relative positions of the four dispensing cylinders 41. The feed chute 421 is provided with a protrusion 423, which allows the pins on both sides of the power transformer to be placed on both sides of the feed chute 421.

[0048] In this embodiment, the marking feed track 73 is supported by a support rod, and the material conveying component 72 is installed on the side of the marking feed track 73. The other side of the marking feed track 73 is used to install and place the marking machine. The marking feed track 73 has a U-shaped structure with a protrusion in the middle of the U-shape. The protrusion forms two grooves on the side of the marking feed track 73 for placing the pins of electronic devices. The marking feed track 73 includes a lifting part 731 and a marking station part 732; the lifting part 731 and the marking station part 732 are disconnected from each other, and the height of the marking station part 732 is higher than the height of the lifting part 731. A lifting component 74 is provided at the lower part of the lifting part 731, which lifts the lifting part 731 to the same height as the marking station part. The material conveying component 72 includes an X-axis moving component 721 and a Y-axis moving component 722, and the Y-axis moving component 722 is connected to a feeding fork. The X-axis moving component 721 and the Y-axis moving component 722 are connected and cooperate with each other, so that the feeding fork can move in both the X-plane and the Y-plane, and the feeding fork can move the device in a certain number of sequences within the marking and feeding track 73.

[0049] In this embodiment, the machine body 1 has an inclined section 11 and a laser marking platform, which is a horizontal structure. Both the high-voltage testing component and the electrical testing component are located on the inclined section 11 of the machine body 1. The laser marking mechanism 7 is located on the laser marking platform. Simultaneously, the material receiving structure is inclinedly located on the side of the laser marking platform of the machine body 1; the feeding mechanism 2, the high-voltage testing mechanism 3, the first material dispensing mechanism 4, the electrical testing mechanism 5, the second material dispensing mechanism 6, the laser marking mechanism 7, and the material receiving mechanism 8 are connected sequentially via a conveying track 9.

[0050] In this embodiment, the laser marking mechanism 7 includes a marking machine body, a material conveying component 72 configured for the marking machine body, and a marking feed track 73. The marking feed track 73 has a lifting part 731 and a marking station part 732. The lifting part 731 is connected to a lifting component 74. The material conveying component 72 includes an X-axis moving component 721 and a Y-axis moving component 722. The X-axis moving component 721 and the Y-axis moving component 722 are connected to each other through a fixing plate 77. The Y-axis moving component 722 is connected to a material-pulling fork, which is used to move a certain number of power transformers on the marking feed track 73. The lifting component 74 lifts the lifting part 731 of the marking feed track 73 upward, and the power transformers in the lifting part 731 are held by the material-pulling fork. The Y-axis moving assembly 722 primarily drives the feeding fork to move in a direction perpendicular to the X-axis moving assembly 721. The X-axis moving assembly, via the fixed plate 77, drives the Y-axis moving assembly 722 to move along the X-axis, thereby moving the power transformer held by the feeding fork within the marking feed track 73 to the marking station 732. A marking plate 76 is mounted on the X-axis moving assembly 721 and is fixed to the laser marking platform with bolts. A notch is provided on the marking plate 76 at a position corresponding to the marking station 732, allowing the marking machine body to perform laser marking on the power transformer at the marking station 732.

[0051] The main body of the marking machine, the material conveying component 72, and the feeding track are all set on the laser marking platform of the machine body 1.

[0052] This invention proposes a marking method for testing dual-in-line packaged power transformers. This marking method is based on a marking machine for testing dual-in-line packaged power transformers and specifically includes the following steps.

[0053] Step 10: Place the power transformer to be tested on the feeding mechanism 2. The feeding mechanism 2 works to continuously feed the power transformer to one end of the high voltage test component in sequence, thus completing the feeding process of the power transformer.

[0054] Step 20: The probes 322 of the high-voltage testing mechanism 3 contact the pins on both sides of the power transformer to perform a high-voltage test on the network transformer.

[0055] Step 30: The first material sorting mechanism 4 screens out the power transformers that fail the high voltage test and transfers the high voltage defective power transformers to the high voltage defective material receiving device 81 through the high voltage defective material receiving track 91. The power transformers that pass the high voltage test are transferred to the electrical testing mechanism 5 through the material conveying track 9; proceed to step 40.

[0056] Step 40: The electrical performance testing mechanism 5 performs electrical performance testing on the power transformers that passed the high-voltage test in step 30; and the second material separating mechanism 6 separates the power transformers that passed the electrical performance test from those that failed the electrical performance test. Specifically, the power transformers that passed the electrical performance test are transferred to the laser marking mechanism 7 for marking, and the power transformers that failed the electrical performance test are transferred to the electrical defect receiving device 82.

[0057] Step 50: The laser marking machine 71 of the laser marking mechanism 7 cooperates with the marking and material distribution mechanism. The marking and material distribution mechanism will process a certain number of materials through the power transformer that has undergone electrical testing, so that the laser marking machine 71 can perform marking operations according to a certain marking procedure.

[0058] Step 60: Transfer the power transformer marked by the laser marking mechanism 7 to the good product receiving device to complete the power transformer testing and marking process.

[0059] Although specific embodiments of the present invention have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
