Description

Technical Field

[0001] The invention relates to the field of inductor detection, and in particular to a detection platform for SMD chip inductors. Background Art

[0002] SMD inductor components are mainly used for filtering, current sampling and voltage conversion functions, so the performance improvement and cost optimization of SMD inductor components are important development directions for the electronics industry. However, the traditional test bench requires operators to operate manually, and because the chip inductor may be attached to the test end during production, transportation or storage, some tiny impurities such as dust, tin scraps, fibers, etc. These impurities may affect the electrical connection during the test, resulting in inaccurate test results. Therefore, before the operator installs the inductor to the test station of the test bench, the operator will first blow the test end of the inductor. These impurities can be removed by blowing to ensure the cleanliness of the test end.

[0003] At the same time, traditional testing platforms tend to operate independently, with low integration with other equipment and systems on the production line, and cannot achieve real-time information sharing and collaborative work, affecting the automation and production efficiency of the entire production process. In addition, the overall automation of existing testing platforms is low. In addition to the manual operation of loading, clamping and unloading, when manually clamping the inductor, due to differences in operators and irregular operations, the clamping force is difficult to control, and it is easy to clamp too loose or too tight. Too loose will cause the inductor to loosen during the test process, affecting the test results, and too tight may damage the inductor and reduce the product qualification rate.

[0004] To this end, we need to make improvements to the traditional testing bench. Summary of the invention

[0039] The elastic pressing mechanism 5 is arranged beside the conveying device 3 and connected to the workbench 1. The elastic pressing mechanism 5 also includes a positioning frame 6, a pressing motor 11, a first bevel gear 12, a second bevel gear 21, a pressing support plate 19, a detection table 27 and a detector 4.

[0042] When the device is in operation, the conveying device 3 moves a number of inductors 2 to the side of the positioning frame 6 in sequence, and then the pressing motor 11 is started, which will eventually drive the pressing support plate 19 to clamp the inductor 2 (the specific process will be described in detail later). At the same time, the detection table 27 will approach the inductor 2 as the pressing motor 11 is started. During this process, the cleaning mechanism 42 will blow air to the upper end of the inductor 2 through the air cylinder 49 to prevent dust accumulation from affecting the detection accuracy of the detector 4 until the detector 4 contacts the inductor 2 and detects the inductor 2. After the detection is completed, the conveying device 3 is started again and drives the inductor 2 to move to the end of the conveying device 3. Then, when the next inductor 2 is detected, since the conveying device 3 stops running at this time, the unloading mechanism 29 is started and the inductor 2 is classified according to the detection result.

After the unloading rack 36 moves, it will drive the unloading pressure plate 37 to move. After the unloading pressure plate 37 moves, it will drive the limit plate 40 to move. When the limit plate 40 moves, the limit roller 39 at its upper end will roll along the lower end of the limit arc plate 41, so the limit arc plate 41 will drive the limit plate 40 to move downward through the limit roller 39, and then the limit plate 40 will drive the inductor 2 at the upper end of the conveying device 3 to fall into the collecting box 31.

[0047] In order to supplement the specific structure of the cleaning mechanism 42, the following features are also specifically provided:

After the downward pressing motor 11 is started, the downward pressing motor 11 will drive the first screw 13 to rotate through the first bevel gear 12, and the first screw 13 will drive the abutting frame 15 to move toward the conveying device 3 through the first screw sleeve 14. The movement of the abutting frame 15 will drive the abutting plate 16 to move. After the abutting plate 16 moves, it will push the abutting support plate 19 to make non-rigid contact with the inductor 2 under the action of the abutting spring 18 to prevent the inductor 2 from being damaged when in rigid contact.

[0057] In order to prevent the pressing support plate 19 from damaging the outer wall of the inductor 2 when the pressing support plate 19 is used to position and clamp the inductor 2, the following features are specifically provided:

[0058] The elastic pressing mechanism 5 further includes a plurality of rubber stoppers 20, which are arranged in an array at equal intervals on the side of the pressing support plate 19 away from the pressing plate 16 (refer to Figure 5 When the pressing support plate 19 and the inductor 2 come into contact, the rubber stoppers 20 will flexibly contact the inductor 2 to prevent the pressing support plate 19 from damaging the inductor 2 after the pressing spring 18 is compressed to the limit state.

[0059] In order to drive the detection platform 27 to move downward, the following features are also specifically provided:

[0060] The elastic pressing mechanism 5 also includes a first pulley 22, a second pulley 23, a second screw sleeve 24, a second screw rod 25 and two limiting guide plates 26.

After the downward pressure motor 11 is started, the downward pressure motor 11 will drive the second bevel gear 21 to rotate through the first bevel gear 12, and the second bevel gear 21 will drive the second pulley 23 to rotate through the first pulley 22 after the rotation, and the second pulley 23 will drive the second screw rod 25 to move through the second screw sleeve 24, and the second screw 25 will drive the detection platform 27 to move after the movement, so as to drive the detector 4 to approach the inductor 2 and detect it.

[0061] The working principle of the device is that when the device is in operation, the conveying device 3 moves a number of inductors 2 to the side of the positioning frame 6 in sequence, and then the pressing motor 11 is started and drives the clamping support plate 19 to approach the inductor 2. During this process, the inductor 2 is clamped. At the same time, the detection table 27 will approach the inductor 2 as the pressing motor 11 is started. During this process, the clamping plate 16 will push the clamping support plate 19 to make non-rigid contact with the inductor 2 under the action of the clamping spring 18 to prevent the inductor 2 from being damaged during rigid contact.

[0062] When the testing platform 27 drives the detector 4 to approach the inductor 2, the testing platform 27 will drive the reciprocating gear 43 to rotate through the reciprocating rack 28. After the reciprocating gear 43 rotates, air will be blown to the upper end of the inductor 2 through the air cylinder 49 to prevent the detection accuracy of the detector 4 from being affected by the accumulation of dust. Finally, the detector 4 contacts the inductor 2 and detects the inductor 2. After the detection is completed, the conveying device 3 is started again and drives the inductor 2 to move to the end of the conveying device 3. Then, when the next inductor 2 is detected, since the conveying device 3 stops running at this time, the unloading motor 33 is started first and drives the unloading pressure plate 37 to move. The movement of the unloading pressure plate 37 will drive the corresponding inductor 2 to fall into the collection box 31, and the cylinder 30 will change the position of the collection box 31 according to the detection result. Then, the inductors 2 that meet the detection standards and the inductors 2 that do not meet the detection standards fall to both sides of the partition 32 in batches.
