Description

Technical Field

[0001] The utility model relates to the technical field of inductance detection, in particular to an automatic return line for inductance characteristic detection. Background Art

[0002] After the inductance of a transformer is produced, its various indicators need to be detected by an interlayer tester, a withstand voltage tester, and a characteristic tester. Only after passing the detection can it be taken off the production line and assembled into the transformer. However, in the prior art, when the inductance is detected online, the inductance is usually manually placed in a positioning jig for positioning, and then the positioning jig is conveyed to the position where the detection instrument is located through a conveyor line for detection.

[0003] Most of the currently used return lines have relatively complex structures. The return line adopts an electric control method, where a motor drives a chain to rotate, thereby driving the positioning jig to be conveyed backward. Or a motor drives a synchronous belt to move to convey the positioning jig backward. The structures of these two driving methods are relatively complex, and the self-weight of the return line is relatively heavy. Motor drive requires cooperation with sensors to accurately monitor the position of the positioning jig, and at the same time, the rotation speed of the motor also needs to be accurately controlled, which has high requirements for the control system and high costs, and it is difficult to meet the production requirements. Summary of the Utility Model

[0010] The positioning fixture includes a bottom plate and a fixture plate fixed on the bottom plate.

The guide rail is fixed on the mounting block. A blocking plate is fixedly provided on the side of the mounting block away from the support plate. A cylinder fixing block is fixedly installed on the lower side of the lifting plate. The transposition cylinder is vertically fixed on the cylinder fixing block. The output end of the transposition cylinder is connected to a connecting rod, and the other end of the connecting rod is rotatably connected to the fixing plate.

The guide rail in the transposition mechanism will be docked with the guide rail on the support plate so that the positioning jig can slide onto the guide rail on the support plate. The transmission of the positioning jig is realized by the pushing mechanism. Therefore, a complex driving structure is required to realize the transmission of the positioning jig.

Specific implementation manner

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] As Figure 1 shown, a preferred embodiment of the present invention proposes an automatic return line for inductance characteristic detection, which is mainly used for detecting the characteristics of inductors and conveying and returning the positioning fixture 4. The automatic return line mainly includes two upper and lower conveying lines and a transposition mechanism 7 provided at both ends of the conveying lines.

[0031] Each conveying line is composed of components such as a support plate 1, a guide rail 2, a slider 3, and a positioning fixture 4. A guide rail 2 is provided on each support plate 1, and the length of the guide rail 2 is consistent with the length of the support plate 1. Six sliders 3 are slidably connected to the guide rail 2, and a positioning fixture 4 is fixedly installed on each slider 3, and the positioning fixture 4 is used for positioning the product. The six positioning fixtures 4 are arranged closely adjacent to each other, and the overall length of the six positioning fixtures 4 arranged in a row is approximately the same as the length of the guide rail 2.

[0032] The two support plates 1 are arranged parallel to each other up and down, and a support plate 1 is vertically fixed at each of the four corners of the support plate 1 for connecting the two support plates 1.

[0033] As Figure 3As shown in the figure, the positioning fixture 4 is composed of a bottom plate 41 and a fixture plate 42. The bottom plate 41 is fixed on the slider 3, and the fixture plate 42 is fixed on the bottom plate 41. A positioning groove 421 with an outer shape adapted to the outer shape of the bottom of the inductor is formed in the middle of the fixture plate 42. Avoidance grooves 422 are formed on both sides of the bottom of the positioning groove 421. When the inductor is inserted into the positioning groove 421, the positive and negative pins at the bottom of the inductor will be inserted into the two avoidance grooves 422 respectively.

[0034] Reference Figure 1 , on the uppermost support plate 1, wiring mechanisms 5 are arranged on both sides of the 4 positioning fixtures 4 located in the middle. The wiring structures on both sides of the positioning fixture 4 will respectively contact the positive and negative poles of the inductor and then be electrically connected to the characteristic detection instrument. The 4 positioning fixtures 4 respectively correspond to 4 characteristic detection instruments, including interlayer testing, withstand voltage testing, and characteristic testing, to test the quality factor of the inductor, the number of turns of the winding and the inter-turn short circuit situation, the insulation performance, etc., and can also accurately measure the true effective values of the primary voltage and current of the inductor, the true effective values of the secondary voltage and current, etc.

[0035] As Figure 2 shown in the figure, the wiring mechanism 5 is composed of a cylinder fixed seat 51, a wiring cylinder 52, a positioning plate 53, and a probe 54. Among them, the cylinder fixed seat 51 is fixed on the support plate 1, the wiring cylinder 52 is horizontally fixed on the cylinder fixed seat 51, the positioning plate 53 is installed and fixed on the output end of the wiring cylinder 52, and the probe 54 passes horizontally through the positioning plate 53, and both ends of the probe 54 extend from both sides of the positioning plate 53. When the positioning fixture 4 loaded with the inductor reaches the specified position, the probe 54 is driven by the wiring cylinder 52 to approach the inductor. The avoidance groove 422 on the fixture plate 42 communicates with the outer wall of the fixture plate 42, so the probe 54 can pass through the avoidance groove 422 to contact the positive and negative pins of the inductor.

[0036] The probe 54 is made of conductive metal material and thus has conductivity. One end of the probe 54 located on both sides of the positioning fixture 4 contacts the positive and negative pins of the inductor, and the other end will be electrically connected to the positive and negative poles of the characteristic detection instrument, so as to detect various performances of the inductor through the characteristic detection instrument.

[0037] Before the test, the inductor on the positioning fixture 4 will be pressed tightly by the pressing mechanism 8 to ensure that the pins of the inductor can be in good contact with the probe 54.

[0038] As Figure 6As shown in the figure, the pressing mechanism 8 is fixed on the uppermost support plate 1. The pressing mechanism 8 is composed of a vertical frame 81, a pressing cylinder 82, an adjusting plate 83, a pressing rod 85 mounting plate 84 and a pressing rod 85. Among them, the vertical frame 81 is fixed on the support plate 1, the pressing cylinder 82 is vertically fixed in the middle of the vertical frame 81, and the output end of the pressing cylinder 82 is fixedly connected with a connecting plate. A strip-shaped hole is formed in the adjusting plate 83, and the strip-shaped hole extends vertically. A bolt is arranged in the strip-shaped hole, and the adjusting plate 83 is fixed on the connecting plate through the bolt, and the vertical height of the adjusting plate 83 can be adjusted through the strip-shaped hole.

[0039] The pressing rod 85 mounting plate 84 is horizontally fixed at the bottom of the adjusting plate 83. There are 12 pressing rods 85 on the pressing rod 85 mounting plate 84. Every three pressing rods 85 are in a group and correspond to a positioning fixture 4 below. The pressing rod 85 is made of an elastic material like rubber to prevent the inductor from being damaged when the pressing rod 85 presses down. According to different types of inductors, the height of the lower end surface of the pressing rod 85 can be adjusted through the adjusting plate 83.

[0040] When detecting the inductor, the feeding mechanism first places the inductors one by one on the positioning fixture 4 on the uppermost support plate 1. After the detection is completed, the discharging mechanism then removes the inductors. Finally, the empty positioning fixture 4 will flow back to the lowermost support plate 1 and then flow back to the uppermost support plate 1 from the other end. The return of the positioning fixture 4 is realized by the transposition mechanism 7.

[0041] As Figure 1 shown in the figure, two transposition mechanisms 7 are respectively arranged at both ends of the two support plates 1, and the upper and lower sides of the transposition mechanism 7 are respectively connected to the same end of the two support plates 1.

[0042] Refer to Figure 5 , the transposition mechanism 7 is composed of a lifting plate 71, a slide rail 72, a fixing plate 73, a mounting block 74, a cylinder fixing block 75, a transposition cylinder 76 and other components. Among them, two plates are fixed on the back of the lifting plate 71, and the two plates are respectively fixed on the two support plates 1 through bolts. The slide rail 72 is vertically fixed on the front of the lifting plate 71, and the fixing plate 73 is connected with the slide rail 72 through a slider 3 and slides up and down. The cylinder fixing block 75 is fixed on the lower side of the lifting plate 71, and the transposition cylinder 76 is vertically fixed on the cylinder fixing block 75. The output end of the transposition cylinder 76 is connected with a connecting rod 77, and the upper end of the connecting rod 77 is rotatably connected with the fixing plate 73. The fixing plate 73 is driven to slide up and down by the transposition cylinder 76.

[0043] The mounting block 74 is perpendicular to the fixed plate 73 and is fixed on the fixed plate 73. Reinforcing ribs 78 are provided at both ends of the lower side of the mounting block 74, which play a supporting role and strengthen the connection between the mounting block 74 and the fixed plate 73. A relatively short guide rail 2 is horizontally fixed on the fixed plate 73. A slider 3 is slidably connected to the guide rail 2, and a positioning jig 4 is fixedly installed on the slider 3. A blocking plate 79 is provided on the side of the mounting block 74 away from the support plate 1, which plays a role in blocking and limiting the positioning jig 4.

[0044] The vacant positioning jig 4 on the uppermost support plate 1 will slide along with the slider 3 onto the guide rail 2 in the transposition mechanism 7 on the right side. Then, the transposition cylinder 76 drives the fixed plate 73 to slide downward, and the guide rail 2 on the mounting block 74 will be docked with the guide rail 2 on the lowermost support plate 1. Next, the vacant positioning jig 4 will slide along with the slider 3 onto the guide rail 2 on the lowermost support plate 1. Similarly, the vacant positioning jig 4 will be driven to move upward by the transposition mechanism 7 on the left side and finally flow back onto the guide rail 2 on the uppermost support plate 1.

[0045] In order to push the slider 3 to move, push mechanisms 6 are provided at both ends of the bottom of the uppermost support plate 1. The two push mechanisms 6 correspond to the two support plates 1 respectively, and are respectively used to push the positioning jigs 4 on the transposition mechanisms 7 on the left and right sides of the support plate 1 onto the guide rails 2 on the two support plates 1.

[0046] As Figure 4 shown, the push mechanism 6 is composed of a cylinder mounting plate 61, a push cylinder 62, and a push plate 63. The cylinder mounting plate 61 is fixed to the bottom of the support plate 1. The push cylinder 62 is horizontally fixed on the cylinder mounting plate 61. The push plate 63 is fixedly connected to the output end of the push cylinder 62. By driving the push plate 63 to move through the push cylinder 62, the positioning jig 4 on the transposition mechanism 7 is pushed along with the slider 3 onto the guide rail 2 on the support plate 1.

[0047] The pushing directions of the two push cylinders 62 are opposite, and the stroke of the push cylinder 62 is consistent with the length of the positioning jig 4. Therefore, the push cylinder 62 can just completely push the positioning jig 4 on the transposition mechanism 7 onto the guide rail 2 on the support plate 1 within the stroke range. When the positioning jig 4 on the transposition mechanism 7 is pushed onto the guide rail 2 on the support plate 1, the positioning jig 4 will continue to push the other positioning jigs 4 on the guide rail 2 backward, so as to realize the transmission of the positioning jigs 4.

[0048] One side of the push plate 63 extends outward and faces the side of the positioning jig 4, so that the shape of the push plate 63 is "L" - shaped. The push plate 63 mainly uses the L - end to push the positioning jig 4 onto the guide rail 2 located on the support plate 1. Among them, the L - end of the push plate 63 on the left side of the support plate 1 faces upward, and the L - end of the push plate 63 on the right side of the support plate 1 faces downward. The blocking plate 79 has a notch, which is matched with the L - end of the push plate 63 and does not hinder the movement of the push plate 63. The push plate 63 can pass through this notch when moving back and forth.

[0049] As Figure 1 shown, when the positioning jig 4 enters the guide rail 2 on the support plate 1, it is necessary to position the positioning jig 4. Therefore, a positioning mechanism 9 is provided at each end of the support plate 1 of the upper and lower two conveyor lines.

[0050] Refer to Figure 7 , the positioning mechanism 9 is composed of a fixing block 91, an adjusting block 92, a positioning rod 93 and a roller 94. Among them, the fixing block 91 is fixed on the support plate 1 by bolts, the adjusting block 92 is fixed on the fixing block 91. There is a jack at the front end of the adjusting block 92, and a strip - shaped hole communicating with the jack is opened at the top of the fixing block 91. After the positioning rod 93 is inserted into the jack, it is fixed by bolts. The roller 94 is rotatably connected to the front end of the positioning rod 93. At the same time, a positioning groove 411 is opened on the side of the jig plate 42. When the positioning jig 4 enters the support plate 1, the roller 94 will cooperate with the positioning groove 411 to position the positioning jig 4. The distance between the roller 94 and the positioning jig 4 can be adjusted through the strip - shaped hole.

[0051] A positioning mechanism 9 is also provided on the fixing plate 73 of the transposition mechanism 7. This positioning mechanism 9 is vertically arranged. At the same time, a positioning groove 411 is also opened on the bottom surface of the jig plate 42. The positioning rod 93 will pass upward through the mounting block 74, and the roller 94 will contact the positioning groove 411 on the bottom surface of the jig plate 42 to position it.

[0052] The above - mentioned technical solutions only reflect the preferred technical solutions of the technical solutions of the present utility model. Some changes that those skilled in the art in this technical field may make to some parts thereof all reflect the principles of the present utility model and fall within the protection scope of the present utility model.
