Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and more specifically, to a resistance testing mechanism. Background Technology

[0002] In the electronic components industry, during the production and assembly process, it is often necessary to perform parameter testing on coil products to determine whether the product is qualified, and resistance testing is one of these tests.

[0003] In resistance testing, whether manual or automated, accuracy is a crucial indicator; deviations can lead to misjudgments. This is especially true for coils with resistances of only a few ohms. Factors such as the circuitry, instrumentation, contact, and temperature of the testing mechanism can significantly interfere with resistance measurements, easily resulting in misjudgments. Misjudging a product with acceptable resistance as defective greatly increases unnecessary production costs, while misjudging defective products as acceptable, allowing them to reach subsequent processes or even customers, presents a serious quality problem.

[0008] The first drive is used to move the insulating pressure plate toward the coil and abut against the frame on one side of the coil, and the insulating pressure block abuts against one side surface of the contact lead of the coil; the second drive is used to move the probe mounting plate toward the coil and make the elastic detection probe abut against the contact lead, forming an elastic compression abutment state.

[0009] Furthermore, the probe mounting plate is provided with multiple insulating blocks, and multiple elastic detection probes are respectively mounted on the insulating blocks; the tail of the elastic detection probe is electrically connected to the resistance detector.

[0010] Furthermore, the insulating pressure plate and the probe mounting plate are arranged opposite each other in the vertical direction; the first drive and the second drive are respectively used to drive the insulating pressure plate and the probe mounting plate to move in the vertical direction.

[0011] Furthermore, the elastic detection probe includes a probe and a spring connected to the bottom of the probe.

[0012] Furthermore, the head of the probe that contacts the contact lead has a groove.

[0013] Furthermore, the coil is positioned on one side and protrudes from the insulating pressure plate, and the protrusion height is adjustable.

[0014] Furthermore, both the first drive and the second drive employ cylinders.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example

[0027] Combination Figures 1 to 6 As shown, this embodiment provides a resistance testing mechanism, including a support base 1, a first drive 2 disposed on the support base 1, an insulating pressure plate 3 connected to the first drive 2, a second drive 4, a probe mounting plate 5 connected to the second drive 4, and a clamping device for clamping a coil 6.

[0028] The insulating pressure plate 3 and the probe mounting plate 5 are arranged opposite to each other; a plurality of insulating pressure blocks 7 are spaced apart on the insulating pressure plate 3; a plurality of elastic detection probes 8 are arranged opposite to the insulating pressure blocks 7 on the probe mounting plate 5, and the elastic detection probes 8 are insulatedly mounted on the probe mounting plate 5; the clamping device is made of insulating material at least in the part that contacts the coil 6, and is used to clamp the coil 6 between the insulating pressure plate 3 and the probe mounting plate 5 in a fixed posture;

[0029] Wherein, the first drive 2 is used to drive the insulating pressure plate 3 to move toward the coil 6 and abut against the frame on one side of the coil 6, and the insulating pressure block 7 abuts against one side surface of the contact lead of the coil 6; the second drive 4 is used to drive the probe mounting plate 5 to move toward the coil 6 and make the elastic detection probe 8 abut against the contact lead, and form an elastic compression abutment state.

[0030] Specifically, in this embodiment, a first drive 2, which is a first cylinder, is provided on the upper side of the support base 1. The insulating pressure plate 3 is connected to the piston rod of the first cylinder and can move vertically under the drive of the first cylinder. The insulating pressure plate 3 is horizontally arranged, and multiple insulating pressure plates 3 are spaced apart on it. A second drive 4, which is a second cylinder, is provided on the lower side of the support base 1. The probe mounting plate 5 is connected to the piston rod of the second cylinder, is opposite to and flush with the insulating pressure plate 3, and moves vertically under the drive of the first cylinder. In this embodiment, multiple insulating blocks 14 are provided on the probe mounting plate 5, and multiple elastic detection probes 8 are respectively mounted on the insulating blocks 14. The tail of the elastic detection probe 8 is electrically connected to the resistance detector. Through the arrangement of the insulating pressure plate 3, the insulating blocks 7, the insulating blocks 14, and the probe mounting plate 5 that can insulate the installation of the elastic detection probes 8, the interference of the detection mechanism's own factors on the resistance detection of the coil 6 is effectively avoided.

[0031] The clamping device, at least the portion in contact with the coil 6, is made of insulating material, and is used to clamp the coil 6 in a fixed posture between the insulating pressure plate 3 and the probe mounting plate 5. Figure 4 As shown, in this embodiment, the coil 6 has two bent first contact leads 9 and second contact leads 10; the orientation is that the ends of the contact leads are set vertically downward.

[0032] like Figure 5 and Figure 6As shown, in this embodiment, the elastic detection probe 8 includes a probe 11 and a spring 12 connected to the bottom of the probe 11. The head of the probe 11 that contacts the contact lead has a groove 13. It is positioned on one side of the coil 6 and protrudes from the insulating pressure plate 3 to accommodate the first contact lead 9. Specifically, when the clamping device clamps the coil 6 in the aforementioned posture between the insulating pressure plate 3 and the probe mounting plate 5, the first drive 2 drives the insulating pressure plate 3 to move downward and abut against the upper frame of the coil 6, while the insulating pressure block 7 abuts against the upper surface of the first contact lead 9 of the coil 6; the second drive 4 drives the probe mounting plate 5 to move upward, so that the first contact lead 9 and the second contact lead 10 are respectively inserted into the groove 13 of the probe 11 head, and are compressed and abutted under the action of the spring 12, thereby ensuring stable contact between the first contact lead 9 and the second contact lead 10 and the probe 11, thus enabling accurate and stable detection and greatly reducing the possibility of misjudgment.

[0033] It should be noted that in this embodiment, since the bend of the second contact lead 10 is very close to the coil 6, the abutment of the insulating pressure plate 3 and the elastic abutment of the probe 11 can achieve stable contact between the probe 11 and the second contact lead 10. However, the bend of the first contact lead 9 is far from the coil 6; therefore, the insulating pressure block 7 needs to abut the upper side of the first contact lead 9 to cooperate with the elastic detection probe 8 to achieve stable contact. In this example, the resistance of six coils 6 can be detected simultaneously to ensure detection efficiency. Of course, in other embodiments, multiple coils 6 can be set for synchronous detection according to actual conditions.

[0034] Preferably, the insulating block 7 is movably connected to the insulating plate 3, thereby adjusting the protrusion height to accommodate different coils 6.

[0035] This resistance testing mechanism has a simple structure, occupies little space, and is widely applicable and compatible. It can be widely used in automated production equipment, as well as in fully automated production lines for components and other fields.
