Description

Technical Field

[0001] This utility model relates to the field of inductance detection technology, and in particular to a multi-station inductance detection device. Background Technology

[0002] After inductor products are manufactured, they generally need to undergo multiple testing processes, such as voltage testing and inductance value testing, to improve the product yield. However, due to the lack of an effective conveying mechanism, each testing unit for inductors is set up independently, requiring manual handling and preventing automated testing, resulting in low testing efficiency. Utility Model Content

[0003] This invention provides a multi-station inductance testing device that can automatically test multiple parameters of inductance, thereby improving testing efficiency.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] This utility model provides a multi-station inductance testing device, including multiple testing mechanisms, a material handling mechanism, and a driving mechanism. The multiple testing mechanisms are used to detect different parameters of the inductance, and are evenly distributed laterally. The material handling mechanism includes a support plate above the testing mechanism and multiple suction nozzles fixed to the support plate for adsorbing inductors. The suction nozzles are evenly distributed laterally, and the spacing between adjacent nozzles is equal to the spacing between adjacent testing mechanisms. The driving mechanism includes a driver, a rotating rod, a vertical guide rail, and a horizontal guide rail. One end of the rotating rod is connected to the driver, and the other end is rotatably connected to the support plate. The driver drives the rotating rod to rotate. The support plate is slidably connected to the vertical guide rail in the vertical direction, and the vertical guide rail is slidably connected to the horizontal guide rail in the horizontal direction.

[0006] In some embodiments, the vertical guide rail is provided with a guide rail groove extending in the vertical direction, and the support plate is connected to a guide rod extending in the vertical direction. The guide rod passes through the guide rail groove and can slide along the guide rail groove.

[0007] In some embodiments, a slider is fixed on the vertical guide rail, and the slider is slidably connected to the horizontal guide rail.

[0008] In some embodiments, the material handling mechanism further includes a connecting tube, a spring, and a bracket. The suction nozzle is disposed below the support plate, the bracket is fixed to the top surface of the support plate, the connecting tube passes through the bracket and the support plate from above and is connected to the suction nozzle, a positioning block is sleeved on the outside of the connecting tube, the positioning block is located on the top surface of the support plate, the spring is sleeved on the outside of the connecting tube, and the upper and lower ends of the spring abut against the bracket and the positioning block, respectively.

[0009] In some embodiments, a defective product collection box is provided on the front side of each inspection unit in the transverse conveying direction.

[0010] In some embodiments, the testing mechanism includes a testing platform with a groove for placing an inductor to be tested.

[0011] In some embodiments, the detection mechanism further includes a plurality of electrode pins fixed to the bottom wall of the groove and used to contact the pins of the inductor to be detected.

[0012] In some embodiments, the number of suction nozzles is one more than the number of detection mechanisms.

[0013] This invention has at least the following beneficial effects: when the driver drives the rotating rod to rotate, the support plate can adaptively slide relative to the vertical guide rail, and the vertical guide rail can also adaptively slide relative to the horizontal guide rail, so that the nozzle can move between adjacent detection mechanisms, thereby moving the inductor that has been detected by the previous detection mechanism to the next detection mechanism, thus automatically detecting multiple parameters of the inductor and improving detection efficiency.

[0022] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0023] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0025] An embodiment of this utility model provides a multi-station inductance detection device, such as... Figure 1-3 As shown, the device includes multiple detection mechanisms 100, a material handling mechanism 200, and a driving mechanism 300. The multiple detection mechanisms 100 are used to detect different parameters of the inductor, such as the voltage and inductance value. The multiple detection mechanisms 100 are evenly distributed laterally to facilitate the delivery of the inductor to each detection mechanism 100, and the spacing between adjacent detection mechanisms 100 can be equal.

[0026] The material handling mechanism 200 includes a support plate 210 located above the detection mechanism 100 and a plurality of suction nozzles 220 fixed on the support plate 210 for adsorbing inductors. The suction nozzles 220 are evenly distributed in the transverse direction, and the distance between adjacent suction nozzles 220 is equal to the distance between adjacent detection mechanisms 100. Thus, the suction nozzles 220 can simultaneously pick up inductors from multiple detection mechanisms 100 at a time.

[0027] The drive mechanism 300 includes a driver, a rotating rod 310, a vertical guide rail 320, and a horizontal guide rail 330. One end of the rotating rod 310 is connected to the driver, and the other end is rotatably connected to the support plate 210. The driver can be a motor or other driving device, which drives the rotating rod 310 to rotate, causing the support plate 210 to swing. The support plate 210 is slidably connected to the vertical guide rail 320 in the vertical direction, and the vertical guide rail 320 is slidably connected to the horizontal guide rail 330 in the horizontal direction.

[0028] When the multi-station inductance detection device of this embodiment is working, the driver first causes the rotating rod 310 to rotate in the conveying direction. The support plate 210 can adaptively slide relative to the vertical guide rail 320, and the vertical guide rail 320 can also adaptively slide relative to the horizontal guide rail 330. The entire support plate 210 swings in a semi-circular manner, and the suction nozzles 220 on the support plate 210 also swing in a semi-circular manner. All the suction nozzles 220 can move the adsorbed inductor to the next detection mechanism 100. Then, the driver drives the rotating rod 310 to rotate in the opposite direction. The entire support plate 210 swings in a reverse semi-circular manner, and the suction nozzles 220 on the support plate 210 also swing in a reverse semi-circular manner. All the suction nozzles 220 return to their original positions and continue to wait to move the next inductor. In this way, the inductors that have been detected by the previous detection mechanism 100 can be continuously moved to the next detection mechanism 100 until all the inductors have been detected. This allows for the automatic detection of multiple parameters of the inductor, improving the detection efficiency.

[0029] It should be noted that the suction nozzle 220 is connected to the negative pressure device, and both the negative pressure device and the driver are connected to the controller. The controller sends corresponding control commands to the negative pressure device and the driver according to the set program, so that the suction nozzle 220 can attract or release the inductor at the appropriate time, and the driver can drive the support plate 210 to swing at the appropriate time, so that they can coordinate with each other to complete the inductor transmission.

[0030] In some embodiments, the multi-station inductance testing device may further include a frame 10, on which the driver, transverse guide rail 320, and testing mechanism 100 may be fixed. The support plate 210 may include a connecting block 260, which is rotatably connected to the rotating rod 310.

[0031] In some embodiments, the vertical guide rail 320 is provided with a guide rail groove extending in the vertical direction, and the support plate 210 is connected to a guide rod 340 extending in the vertical direction. The guide rod 340 passes through the guide rail groove and can slide along the guide rail groove. When the support plate 210 moves in the vertical direction, the guide rod 340 slides in the guide rail groove, and the sliding position of the support plate 210 relative to the vertical guide rail 320 is limited by the cooperation between the guide rod 340 and the guide rail groove.

[0032] Furthermore, a slider 350 is fixed on the vertical guide rail 320, and the slider 350 is slidably connected to the horizontal guide rail 330, thereby realizing the horizontal sliding connection between the vertical guide rail 320 and the horizontal guide rail 330.

[0033] In some embodiments, the material handling mechanism 200 further includes a connecting pipe 230, a spring 250, and a bracket 240. A suction nozzle 220 is disposed below a support plate 210. The bracket 240 is fixed to the top surface of the support plate 210. The connecting pipe 230 passes through the bracket 240 and the support plate 210 from above and connects to the suction nozzle 220. The suction nozzle 220 is connected to a negative pressure device via the connecting pipe 230. A positioning block 270 is sleeved on the outer side of the connecting pipe 230, located on the top surface of the support plate 210. The spring 250 is sleeved on the outer side of the connecting pipe 230, with its upper and lower ends abutting against the bracket 240 and the positioning block 270, respectively. The spring 250 applies a force, causing the positioning block 270 to abut against the top surface of the support plate 210, and the position of the suction nozzle 220 relative to the support plate 210 remains stable without external force.

[0034] When the driver causes the support plate 210 to move downwards by too much distance, the nozzle 220 will exceed the ideal position for attracting the inductor. The nozzle 220 will press down on the inductor. This force will overcome the elastic force applied by the spring 250, allowing the nozzle 220 and the connecting tube 230 to move upwards relative to the support plate 210. That is, the nozzle 220 can elastically extend and retract in the vertical direction, avoiding the support plate 210 from moving downwards by too much distance, which would cause the nozzle 220 to make rigid contact with the inductor. This structure will not damage the inductor.

[0035] In some embodiments, a defective product collection box 110 is provided on the front side of each detection mechanism 100 in the transverse conveying direction. When the detection mechanism 100 detects that the inductor is defective, the suction nozzle 220 moves the inductor to the next detection mechanism 100. During this process, the suction nozzle 220 can release the suction of the inductor, and the inductor naturally falls into the defective product collection box 110, thereby removing the defective product in time without having to re-detect the defective product.

[0036] In some embodiments, the testing mechanism 100 includes a testing stage 120, on which a groove 130 is provided. The groove 130 is used to place the inductor to be tested, and the inductor is positioned by the groove 130 to avoid unsatisfactory placement.

[0037] Furthermore, the detection mechanism 100 also includes multiple electrode pins 140, which are fixed to the bottom wall of the groove 130 and used to contact the leads of the inductor to be tested. By contacting the leads of the inductor, the parameters of the inductor during operation can be obtained. The electrode pins 140 are naturally connected to the relevant detection circuit. Since the detection circuit is already in the prior art, its specific structure will not be described in detail.

[0038] In some embodiments, the number of suction nozzles 220 is one more than the number of detection mechanisms 100. Figure 1For example, the first suction nozzle 220 from the rightmost position can pick up the inductor transported by the external conveying track and place the inductor on the first detection mechanism 100. The second suction nozzle 220 then transports the inductor on the first detection mechanism 100 to the second detection mechanism 100, and so on. The last suction nozzle 220 then transports the inductor on the last detection mechanism 100 to the next station. This can be coordinated with the external conveying track and the downward moving station to facilitate the fully automated production of inductors.
