[0002] Surface mount ferrite bead (SMD) testing equipment is specifically designed for testing the electrical performance and physical parameters of SMD beads. It is widely used in quality control, R&D, and production processes in the electronics manufacturing industry. Its core function is to verify whether the ferrite bead meets design specifications through precise circuit connections and signal analysis, ensuring its effective filtering, interference suppression, and high-frequency noise suppression capabilities within the circuit. These devices typically consist of a main unit (containing core modules such as a signal generator, impedance analyzer, and LCR meter), dedicated fixtures (using miniature probes or conductive contacts to reliably connect the bead pins to the test circuit), and automated auxiliary mechanisms. During testing, the device applies a specific frequency electrical signal to the SMD bead and measures key parameters such as impedance, DC resistance, rated current, and resonant frequency to determine if the bead exhibits performance abnormalities (such as substandard impedance, excessive internal resistance, or insufficient high-frequency suppression).

[0003] Existing surface mount ferrite bead testing devices suffer from low testing efficiency due to the small size and large number of surface mount beads. Furthermore, these devices lack the ability to automatically unload the beads after testing, resulting in limited practicality. Therefore, a new surface mount ferrite bead testing device is needed to address these issues. Utility Model Content

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1-4As shown, this utility model provides a technical solution: a patch magnetic bead testing device, including a testing platform 1, a plurality of support legs 106 fixedly connected to the bottom end of the testing platform 1, a base 107 fixedly connected between the bottom ends of the plurality of support legs 106, a side frame 103 fixedly connected to the top end of the testing platform 1, a detection component 2 provided at the top end of the side frame 103, a limiting plate 104 fixedly connected to the top end of the testing platform 1, a plurality of spaced partitions 105 fixedly connected to the side end of the limiting plate 104, and a plurality of air holes 102 opened at the top end of the testing platform 1, with each air hole 102 located between two adjacent partitions 105. A vacuum assembly 3 is provided between the bottom of the testing platform 1 and the top of the base 107. A mounting groove 101 is provided at the top of the testing platform 1. A translation assembly 4 is provided inside the mounting groove 101. A pusher assembly 5 is provided between the outer end of the translation assembly 4 and the top of the testing platform 1. The vacuum assembly 3 and the air hole 102 facilitate the adsorption and fixation of several patches on the top of the testing platform 1. The detection assembly 2 facilitates the detection and inspection of several patches that are fixed at the same time. The translation assembly 4 and the pusher assembly 5 facilitate the automatic unloading of patches after inspection, thus improving the practicality of the device.

[0017] As one implementation method in this embodiment, such as Figure 1 and Figure 2 As shown, the vacuum assembly 3 includes several connecting pipes 301, which are fixedly connected to the bottom of the testing platform 1 near each air hole 102. A connecting plate 302 is fixedly connected between the bottom ends of the connecting pipes 301. A vacuum pump 303 is fixedly installed at the top of the base 107. An input pipe 304 is installed at the input end of the vacuum pump 303, and the top end of the input pipe 304 is fixedly connected to the bottom end of the connecting plate 302. An output pipe 305 is installed at the output end of the vacuum pump 303. Several round rods are fixedly connected between the bottom end of the connecting plate 302 and the top end of the base 107. 306. In practice, after each patch is placed on the top of the detection stage 1, the patches can be placed sequentially and separated in each row due to the limiting effect of several partitions 105. After each patch is placed, its bottom will be aligned with the position of the air hole 102. At this time, by starting the vacuum pump 303, the gas at the bottom of each patch is drawn into the input pipe 304 through several air holes 102, several connecting pipes 301 and connecting plate 302, and finally output from the output pipe 305. Thus, each patch can be simultaneously adsorbed and fixed, which makes it convenient for the detection component 2 to detect each patch at the same time.

[0018] As one implementation method in this embodiment, such as Figure 2As shown, the detection component 2 includes a cylinder 201, which is fixedly installed on the top of the side frame 103. A connecting plate 202 is installed on the telescopic end of the cylinder 201, and several probes 203 are fixedly installed on the bottom end of the connecting plate 202. In practice, by starting the cylinder 201, the connecting plate 202 and the probes 203 are driven to move downward. After each probe 203 contacts the patch, it detects the patch. Therefore, this device can simultaneously adsorb, fix and detect multiple patches, improving the detection efficiency of the patches.

[0019] As one implementation method in this embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, the translation component 4 includes a motor 401, which is fixedly mounted on the side of the detection table 1. A screw 402 is installed at the output end of the motor 401. The screw 402 is inserted into the interior of the mounting groove 101, and the side end of the screw 402 is rotatably disposed inside the mounting groove 101. A screw sleeve 404 is threadedly connected to the outer end of the screw 402. Side plates 405 are fixedly connected to both the left and right sides of the screw sleeve 404. A guide rod 403 is fixedly connected to the interior of the mounting groove 101. The top side end of the screw sleeve 404 is sleeved on the outer end of the guide rod 403. The pushing component 5 includes a push plate 501, which is fixedly connected to the side end of the screw sleeve 404. The side end of the push plate 501 is fixedly connected to... A straight plate 502 is provided, and a baffle 503 is fixedly connected to the side end of the straight plate 502. The bottom ends of the push plate 501 and the baffle 503 are inserted between every two partitions 105. In practice, the screw 402 is rotated by starting the motor 401. At this time, due to the limit of the threaded sleeve 404 by the guide rod 403, the threaded sleeve 404 can be moved horizontally. At this time, the threaded sleeve 404 drives the push plate 501 and the baffle 503 to move horizontally. At this time, the push plate 501 can push the patch between the partitions 105 to feed it out. The function of the baffle 503 is to block the patch between the partitions 105 when it is not fed out, so as to prevent the patch from falling off the detection table 1. After the detection is completed, it is convenient to automatically feed the patch, which improves the practicality of the device.

[0020] Working principle: After each patch is placed on the top of the detection stage 1, the patches are positioned sequentially by several partitions 105, ensuring separation between rows. Once placed, the bottom of each patch aligns with the vent 102. The vacuum pump 303 then draws the gas from the bottom of each patch through the vents 102, connecting pipes 301, and connecting plate 302 into the input pipe 304, and finally outputs it from the output pipe 305. This allows for simultaneous adsorption and fixation of each patch, facilitating simultaneous detection of each patch by the detection component 2. The cylinder 201 moves the connecting plate 202 and probe 203 downwards, allowing each probe 203 to contact and detect the patch. Therefore, this device can simultaneously... Multiple patches are adsorbed, fixed, and detected to improve the detection efficiency. Then, gas is sent into the input pipe 304, the connecting plate 302, and each connecting pipe 301 through the output pipe 305. When each air hole 102 is vented, the patch loses its fixing effect. The motor 401 is started to drive the screw 402 to rotate. At this time, due to the limit of the guide rod 403 on the screw sleeve 404, the screw sleeve 404 can be driven to move horizontally. The screw sleeve 404 drives the push plate 501 and the baffle 503 to move horizontally. At this time, the push plate 501 can push the patch between the partitions 105 to be unloaded. The function of the baffle 503 is to block the patch between the partitions 105 when it is not unloaded, so as to prevent the patch from falling off the detection stage 1. After the detection is completed, it is convenient to automatically unload the patch, which improves the practicality of the device.
