Description

Technical Field

[0001] This utility model belongs to the field of transformer manufacturing technology, specifically relating to a visual inspection mechanism for a pin insertion machine and a pin insertion machine. Background Technology

[0002] Transformers are core components in power systems and electronic equipment, enabling voltage transformation, current transformation, impedance matching, and electrical isolation. A transformer's structure typically includes a core, windings, a frame, and leads. In the transformer manufacturing process, the lead insertion process, or pin insertion process, is a crucial step in connecting the frame to the external circuitry, directly affecting the transformer's assembly accuracy and product quality. Currently, the pin insertion operation is mainly completed using a pin insertion machine. Pin holes are pre-set on the frame, and the pin insertion machine inserts the leads into these holes to achieve the transformer's electrical connection.

[0003] However, after the pin insertion machine completes the pin insertion operation, the quality inspection of the pins still largely relies on manual labor. Operators need to visually inspect each pin, or use simple tools, to check for defects such as bent or broken pins. Manually inspecting the pin quality of transformers suffers from low efficiency and inconsistent inspection accuracy. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a visual inspection mechanism and a pin insertion machine. Through a first visual inspection component and a second visual inspection component, images before and after the insertion of the skeleton pin can be acquired respectively, thereby improving the accuracy and efficiency of skeleton visual inspection.

[0005] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0006] In a first aspect, this utility model provides a visual inspection mechanism for a pin insertion machine, including a guide rail, inclined for conveying a skeleton, the guide rail including a first conveying section and a second conveying section, the first conveying section having a first detection position for visual inspection of the skeleton before pin insertion, and the second conveying section having a second detection position for visual inspection of the skeleton after pin insertion; a first visual inspection component, located at the first detection position, for acquiring an image of the skeleton before pin insertion; a clamping component, located at the first detection position, for clamping the skeleton at the first detection position; a second visual inspection component, located at the second detection position, for acquiring an image of the skeleton after pin insertion; and a blocking component, located at the second detection position, for blocking the skeleton from being unloaded at the second detection position.

[0007] In some implementations, the first conveying section has a detection hole at the first detection position, and the first visual detection component includes: a first collector for collecting an image of the top of the skeleton in front of the pin, the collection end of the first collector being provided with a first light source; and a second collector for collecting an image of the bottom of the skeleton in front of the pin, the second collector being disposed on one side of the detection hole and opposite to the first collector, the collection end of the second collector being provided with a second light source.

[0008] In some implementations, the first conveying section includes a limiting part, and the clamping assembly includes: a clamping block disposed opposite to the limiting part; and a clamping drive member connected to the clamping block in a transmission manner. The clamping drive member drives the clamping block to approach the limiting part, and the clamping block cooperates with the limiting part to restrict the sliding of the skeleton. The skeleton is fixed at the first detection position.

[0009] In some implementations, a material collection assembly is provided on the first conveying section, and defective skeletons detected by the first vision inspection assembly are collected at the material collection assembly.

[0010] In some implementations, a material collection port is provided on the first conveying section, and the material collection assembly includes: a connecting block, which is inserted through the first conveying section and opens or closes the material collection port; and a connecting drive member, which is pulsatorically connected to the connecting block and is used to drive the connecting block to open or close the material collection port.

[0011] In some implementations, the second visual detection component includes: a third collector for acquiring an image of the top of the skeleton after the pin is inserted, the acquisition end of the third collector being provided with a third light source; and a fourth collector for acquiring an image of the side of the skeleton after the pin is inserted, the acquisition end of the fourth collector being provided with a fourth light source.

[0012] In some implementations, the material blocking assembly includes: a material blocking plate rotatably disposed on the second conveying section, the material blocking plate blocking the skeleton to stop the skeleton at the second detection position; and a material blocking drive member pulsatorically connected to the material blocking plate, the material blocking drive member driving the material blocking plate to enter or exit the second conveying section.

[0013] In some implementations, the second conveying section is provided with a material distribution component at the end of the skeleton conveying direction.

[0014] In some implementations, the material distribution assembly includes: a material distribution track, including a first channel for collecting qualified skeletons and a second channel for collecting unqualified skeletons; a rotating plate, rotatably disposed at the connection between the first channel and the second channel; and a rotation drive, pulsatorically connected to the rotating plate, the rotation drive driving the rotating plate to close the first channel or the second channel.

[0015] Secondly, this utility model provides a pin insertion machine, including the visual inspection mechanism of the pin insertion machine described above, wherein a pin insertion position for the skeleton pin is provided between the first conveying section and the second conveying section.

[0016] In summary, this utility model has at least the following advantages:

[0017] 1. The visual inspection mechanism of the pin insertion machine provided by this utility model involves conveying the skeleton along a guide rail. First, the skeleton is loaded onto the first conveying section. The skeleton slides along the inclined first conveying section to the first inspection position. A clamping assembly clamps the skeleton at the first inspection position, positioning the skeleton. The first visual inspection assembly can capture an image of the skeleton before pin insertion, completing the visual inspection of the skeleton before pin insertion. Subsequently, the clamping assembly releases the skeleton at the first inspection position. Qualified skeletons can be conveyed along the first conveying section for pin insertion, while unqualified skeletons are unloaded and leave the first conveying section.

[0018] The skeleton after pin insertion is conveyed on the second conveying section. When the skeleton is conveyed to the second detection position, the blocking component blocks the skeleton from being conveyed and unloaded along the second conveying section. The second vision detection component performs image acquisition on the skeleton blocked at the second detection position after pin insertion. The skeleton undergoes a second vision detection after pin insertion.

[0019] The first and second vision inspection components acquire images of the skeleton's appearance for visual inspection. Compared with manual inspection, this can improve inspection and overall production efficiency. At the same time, manual visual inspection is affected by human factors during long-term visual inspection, which increases the probability of missed or false detections of the skeleton. The two-stage visual inspection by the first and second vision inspection components helps to solve the problem of low appearance inspection accuracy and accurately identify skeletons with defects.

[0020] 2. The pin insertion machine provided by this utility model can perform visual inspection before and after the insertion of the skeleton pin, and has high inspection accuracy and convenient operation, ensuring the quality of the product pin insertion. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] Example 1:

[0040] Please see Figure 1 and Figure 2 The visual inspection mechanism of the pin insertion machine of this utility model can be used in the pin insertion process of transformers, that is, in the operation of inserting pins into the preset pin holes of the skeleton 9, the skeleton 9 before and after pin insertion are visually inspected, which can improve the accuracy and efficiency of pin insertion of the skeleton 9.

[0041] The visual inspection mechanism of the pin insertion machine of this utility model includes a guide rail 1, which is inclined to transport a skeleton 9. The skeleton 9 can slide along the guide rail 1 under the action of gravity. The guide rail 1 includes a first conveying section 11 and a second conveying section 12. The first conveying section 11 is provided with a first detection position 111 for visual inspection of the skeleton 9 before pin insertion, and the second conveying section 12 is provided with a second detection position 121 for visual inspection of the skeleton 9 after pin insertion.

[0042] A first visual detection component 2 is provided at the first detection position 111 of the first conveying section 11. The first visual detection component 2 acquires an image in front of the insertion pin of the skeleton 9. In a preferred embodiment, a detection hole 112 is provided through the first conveying section 11 at the first detection position 111. The detection hole 112 can be specifically set on the bottom wall of the first conveying section 11.

[0043] The first visual inspection component 2 includes a first acquisition unit 21 for acquiring images of the top of the pre-attachment skeleton 9. Specifically, the first acquisition unit 21 may be a camera, which is located on top of the first transport section 11. The acquisition end of the first acquisition unit 21 is provided with a first light source 22. Specifically, the first light source 22 may be a first aperture. The first acquisition unit 21 adjusts the light flux through the first aperture, thereby adjusting the image clarity captured by the first acquisition unit 21 to achieve high-quality image acquisition. The first acquisition unit 21 and the first aperture can detect the contour and surface defects of the skeleton 9, such as minor scratches and deformations, on the top of the skeleton 9.

[0044] The first conveying section 11 is provided with a second collector 23 at the bottom of the detection hole 112. The second collector 23 is used to collect the image of the bottom of the skeleton 9 before the insertion pin. The second collector 23 is set opposite to the first collector 21. Specifically, the second collector 23 and the first collector 21 are set coaxially, which is beneficial to the accurate positioning of the skeleton 9. The second collector 23 can be a camera.

[0045] The second collector 23 is equipped with a second light source 24 at its acquisition end. Specifically, the second light source 24 can be a second aperture. The second collector 23 adjusts the light flux through the second aperture. Similarly, the second collector 23 and the second aperture can detect the contour and surface defects of the skeleton 9 at the bottom of the skeleton 9 through the detection hole 112.

[0046] The first conveying section 11 is equipped with a clamping component 3 at the first detection position 111. The clamping component 3 clamps the skeleton 9 at the first detection position 111, and the skeleton 9 is positioned, which is conducive to the first vision detection component 2 to accurately photograph and detect the appearance of the skeleton 9.

[0047] The second conveying section 12 is provided with a second visual detection component 4 at the second detection position 121. The second visual detection component 4 acquires the image after the skeleton 9 is pinned. In a preferred embodiment, the second visual detection component 4 includes a third acquisition device 41. Specifically, the third acquisition device 41 can be a camera and is located on the top of the second conveying section 12. The third acquisition device 41 is used to acquire the image of the top of the skeleton 9 after the pin is inserted.

[0048] The acquisition end of the third acquisition device 41 is equipped with a third light source 42. Specifically, the third light source 42 can be a third aperture. The third acquisition device 41 adjusts the light flux through the third aperture. The third acquisition device 41 and the third aperture can detect the contour and surface defects of the skeleton 9 after the pins are inserted on the top of the skeleton 9.

[0049] A fourth collector 43 is provided on one side of the second conveying section 12 along the conveying direction of the skeleton 9. The fourth collector 43 is used to collect images of the side of the skeleton 9 after the pin is inserted. The acquisition section of the fourth collector 43 is provided with a fourth light source 44. Specifically, the fourth light source 44 can be a fourth aperture. The fourth collector 43 adjusts the light flux through the fourth aperture. The fourth collector 43 and the fourth aperture can detect the contour and surface defects of the skeleton 9 after the pin is inserted on the side of the skeleton 9. The third collector 41 and the fourth collector 43 can collect images of the skeleton 9 after the pin is inserted to detect whether there are problems such as bent pins, pins that are too long or too short.

[0050] In some specific embodiments, an operating platform is provided on one side of the guide rail 1, and multiple support structures 25 are provided on the operating platform. The first collector 21, the second collector 23, the third collector 41, and the fourth collector 43 are all mounted on their respective support structures. Specifically, the support structure 25 includes a support frame 251, on which a proximal slider 253 and a distal slider 252 are slidably mounted. It can be understood that the proximal slider 253 and the distal slider 252 are relative to the distance between them and the guide rail 1, and both the proximal slider 253 and the distal slider 252 can be locked on the support frame 251 by bolts. The first collector 21, the second collector 23, the third collector 41, and the fourth collector 43 are respectively mounted on the corresponding far-end slider 252, and the first light source 22, the second light source 24, the third light source 42, and the fourth light source 44 are respectively mounted on the corresponding near-end slider 253. By adjusting the distance between the far-end slider 252 and the near-end slider 253, the distance between the far-end slider 252 and the first conveying section 11, and the distance between the near-end slider 253 and the first conveying section 11, it is beneficial for the first collector 21, the second collector 23, the third collector 41, and the fourth collector 43 to be accurately positioned and focused, thereby obtaining a clear image and making it flexible to use.

[0051] Furthermore, the first collector 21, the second collector 23, the third collector 41, and the fourth collector 43 are all connected to an adjustment drive 254. The adjustment drive 254 is preferably, but not limited to, a linear module or a cylinder. The adjustment drive 254 is mounted on the corresponding support frame 251. The first collector 21, the second collector 23, the third collector 41, and the fourth collector 43 can further adjust their distance from the guide rail 1 through the corresponding adjustment drive 254, thereby improving alignment accuracy.

[0052] In some specific embodiments, the support structure 25 at the third collector 41 is driven by a translational drive for moving the support structure 25 along the conveying direction perpendicular to the second conveying section 12. Specifically, the support frame 251 is driven by the translational drive, which preferably, but is not limited to, a linear module or a cylinder. The translational drive drives the support frame 251 to move closer to or away from the second conveying section 12, and the support frame 251 drives the third collector 41 and the third light source 42 to move closer to or away from the top of the second conveying section 12. The positions of the third collector 41 and the third light source 42 can be adjusted to be aligned with the skeleton 9 at the second detection position 121.

[0053] The second conveying section 12 is equipped with a material blocking component 5 at the second detection position 121. The material blocking component 5 blocks the skeleton 9 from being fed into the second detection position 121. The second vision detection component 4 can acquire images of the skeleton 9 at the second detection position 121.

[0054] During the visual inspection process, the skeleton 9 is first fed onto the first conveying section 11. The skeleton 9 slides along the first conveying section 11 to the first detection position 111. The clamping assembly 3 clamps the skeleton 9 to fix it. The first collector 21 in the first visual inspection assembly 2 collects the image of the top of the skeleton 9, and the second collector 23 collects the image of the bottom of the skeleton 9 through the detection hole 112. Based on the images collected by the first collector 21 and the second collector 23, the first visual inspection assembly 2 can determine whether there are defects on the surface of the skeleton 9 before the pin insertion. The skeleton 9 completes the first visual inspection.

[0055] The skeleton 9 continues to be conveyed along the first conveying section 11. After the skeleton 9 completes the pin insertion operation, the skeleton 9 with the pin inserted is conveyed on the second conveying section 12. When the skeleton 9 slides to the second detection position 121, the material blocking component 5 blocks the skeleton 9 from continuing to feed. The skeleton 9 stays on the second detection position 121. The second vision detection component 4 collects the appearance of the skeleton 9 after the pin insertion. Among them, the third collector 41 collects the image of the top of the skeleton 9, and the fourth collector 43 collects the image of the side of the skeleton 9 to judge the pin insertion effect of the skeleton 9. The skeleton 9 completes the second vision detection.

[0056] Automated visual inspection of the skeleton 9 using the first visual inspection component 2 and the second visual inspection component 4 improves inspection efficiency. Furthermore, compared to manual inspection, the first and second visual inspection components 2 and 4 reduce the impact of subjective factors on inspection results, minimizing missed and false detections, thus improving inspection accuracy. Visual inspection of the skeleton 9 before and after pin insertion reduces the flow of defective products into subsequent processes, improving production stability.

[0057] Example 2:

[0058] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 2 and Figure 3 In this embodiment, the first conveying section 11 includes a limiting part 113, and the clamping assembly 3 includes a clamping block 31. The clamping block 31 is disposed opposite to the limiting part 113. Specifically, the limiting part 113 can be inserted into the first conveying section 11. When the clamping block 31 enters the first detection position 111, it can cooperate with the limiting part 113 to fix the skeleton 9.

[0059] The clamping block 31 is driven by a clamping drive 32, which is preferably, but not limited to, a cylinder. The output end of the clamping drive 32 is driven by the clamping block 31, and can push the clamping block 31 into or out of the first detection position 111 to move closer to or away from the limiting part 113. In some specific embodiments, a first sensor for sensing that the skeleton 9 is about to enter the first detection position 111 is provided on the first conveying section 11. The first sensor is provided on the first conveying section 11.

[0060] When the skeleton 9 slides along the first conveying section 11 and passes the first sensor, the first sensor senses the skeleton 9, and the clamping drive 32 drives the clamping block 31 to extend into the first detection position 111. The clamping block 31 approaches the limiting part 113, and the distance between the clamping block 31 and the limiting part 113 is reduced to restrict the skeleton 9 from continuing to slide along the first conveying section 11. The clamping assembly 3 fixes the skeleton 9, and the first vision detection assembly 2 acquires images of the skeleton 9.

[0061] Please see Figure 1 and Figure 5 In a preferred embodiment, the baffle assembly 5 includes a baffle plate 51, which is rotatably disposed on the second conveying section 12. Specifically, the baffle plate 51 includes a baffle part. When the baffle plate 51 rotates, the baffle part enters or leaves the second conveying section 12. When the baffle part enters the second conveying section 12, the baffle part prevents the skeleton 9 from continuing to be conveyed along the second conveying section 12, so that the skeleton 9 stops at the second detection position 121. At the same time, the baffle plate 51 can realize the separation of the skeleton 9, so that the skeleton 9 that has been detected by the second vision detection assembly 4 can be individually unloaded.

[0062] The baffle plate 51 is connected to a baffle drive component. Specifically, the baffle drive component is preferably, but not limited to, a motor. The baffle plate 51 is driven to rotate by the baffle drive component. The baffle plate 51 can block the skeleton 9 at the second detection position 121. The second vision detection component 4 performs image acquisition on the skeleton 9 after the pin is inserted.

[0063] Example 3:

[0064] The difference between this embodiment and the above embodiments is that, please refer to [link / reference needed]. Figure 2 and Figure 3 In this embodiment, a material collection component 6 is provided on the first conveying section 11, and the unqualified skeletons 9 detected by the first vision inspection component 2 are collected at the material collection component 6.

[0065] In a preferred embodiment, a collection port 114 is provided on the first conveying section 11, and the collection port is located on one side of the detection port 112. Specifically, a collection channel is provided at the collection port 114 of the first conveying section 11. Unqualified skeletons 9 detected by the first vision detection component 2 can enter the collection channel through the collection port 114 to achieve defective product collection.

[0066] The material collection assembly 6 includes a connecting block 61, which is movably mounted on the first conveying section 11. The connecting block 61 opens or closes the material collection port 114. When the connecting block 61 closes the material collection port 114, the qualified skeleton 9 can slide on the connecting block 61 and continue to be conveyed along the first conveying section 11 after passing the connecting block 61. When the connecting block 61 opens the material collection port 114, the unqualified skeleton 9 falls from the material collection port 114 into the material collection channel.

[0067] The connecting block 61 is connected to a connecting drive component 62. Specifically, the connecting drive component 62 is preferably, but not limited to, a cylinder. When the first vision detection component 2 detects a qualified skeleton 9, the connecting block 61 passes through the first conveying section 11, the collection port 114 is closed, the clamping component 3 releases the qualified skeleton 9, and the qualified skeleton 9 can continue to be conveyed along the first conveying section 11. When the first vision detection component 2 detects an unqualified skeleton 9, the connecting drive component 62 drives the connecting block 61 to exit the first conveying section 11, the collection port 114 is opened, the clamping component 3 releases the unqualified skeleton 9, and the unqualified skeleton 9 falls from the collection port 114 into the collection channel.

[0068] Please see Figure 4 and Figure 5 In a preferred embodiment, a material separating component 7 is provided at the end of the second conveying section 12 in the conveying direction of the skeleton 9. The material separating component 7 distinguishes between qualified and unqualified products detected by the second visual inspection component 4. Specifically, the material separating component 7 includes a material separating track 71, which is connected to the second conveying section 12 and is inclined. The material separating channel includes a first channel 711 for collecting qualified skeletons 9 and a first channel 711 for collecting unqualified skeletons 9.

[0069] A rotating plate 72 is rotatably mounted on the material distribution track 71. The rotating plate 72 is located at the connection between the first channel 711 and the second channel 712. Specifically, the rotating plate 72 can be vertically mounted to separate the first channel 711 and the second channel 712. The rotating plate 72 is driven by a rotating drive component 73, which is preferably, but not limited to, a motor. When the rotating drive component 73 drives the rotating plate 72 to rotate into the first channel 711, the rotating plate 72 closes the first channel 711. When the rotating plate 72 rotates into the second channel 712, the rotating plate 72 closes the second channel 712.

[0070] When the second vision detection component 4 detects a qualified skeleton 9, the rotation drive 73 drives the rotating plate 72 to close the second channel 712, while the first channel 711 remains open. The baffle plate 51 rotates and leaves the second conveying section 12, allowing qualified skeleton 9 to be collected along the second conveying section 12 and the first channel 711. When the second vision detection component 4 detects a defective skeleton 9, the rotation drive 73 drives the rotating plate 72 to close the first channel 711, while the second channel 712 remains open. The baffle plate 51 rotates and leaves the second conveying section 12, allowing defective skeleton 9 to be collected along the second conveying section 12 and the second channel 712.

[0071] The material separating component 7 distinguishes between qualified and unqualified skeletons 9, which facilitates rapid material separation and thus improves production efficiency.
