Description

Technical Field

[0001] The present invention relates to the technical field of processing equipment, and in particular to a resistance testing mechanism. Background Art

[0002] Currently 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 them.

[0003] Whether the resistance test is manual or automated, detection accuracy is an important indicator, and detection deviations can cause misjudgments. Especially for coils with a resistance of several ohms, the circuits, instruments, contacts, and temperatures of the detection mechanism will have a great interference with the resistance detection, which can easily lead to misjudgments. If a product with qualified resistance is misjudged as unqualified, it will greatly increase the unnecessary cost of production. If an unqualified product is misjudged as a qualified product, and the unqualified product flows to the subsequent process or even to the customer, it will be a serious quality problem. Summary of the invention

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

[0009] Furthermore, a plurality of insulating blocks are arranged on the probe mounting plate, and a plurality of the elastic detection probes are respectively mounted on the insulating blocks; and the tails of the elastic detection probes are electrically connected to the resistance detector.

[0010] Furthermore, the insulating pressure plate and the probe mounting plate are arranged opposite to 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 in contact with the contact lead pin has a groove.

[0013] Furthermore, one side of the coil is protruded outside the insulating pressing plate, and the protruding height can be flexibly adjusted.

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

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

[0026] Example

[0027] Combination Figures 1 to 6 As shown, this embodiment provides a resistance testing mechanism, including a support seat 1, a first drive 2 arranged on the support seat 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 arranged at intervals on the insulating pressure plate 3; a plurality of elastic detection probes 8 are arranged on the probe 11 mounting plate 5 opposite to the insulating pressure blocks 7, and the elastic detection probes 8 are insulated and mounted on the probe mounting plate 5; at least the part of the clamping device in contact with the coil 6 is made of insulating material, 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] Among them, the first drive 2 is used to drive the insulating pressure plate 3 to move toward the coil 6, and abut against the skeleton on one side of the coil 6, and the insulating pressure block 7 abuts against the side surface of the contact lead-out pin 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-out pin, and form an elastic compression abutment state.

[0030] Specifically, in this embodiment, a first drive 2 is provided on the upper side of the support seat 1, and the first drive 2 is a first cylinder; the insulating platen 3 is connected to the piston rod of the first cylinder, and can move in the vertical direction under the drive of the first cylinder. The insulating platen 3 is arranged horizontally, and a plurality of insulating platens 3 are arranged at intervals thereon. A second drive 4 is provided on the lower side of the support seat 1, and the second drive 4 is a second cylinder; the probe mounting plate 5 is connected to the piston rod of the second cylinder, and is arranged opposite and flush with the insulating platen 3, and moves in the vertical direction under the drive of the first cylinder. In this embodiment, a plurality of insulating blocks 14 are provided on the probe mounting plate 5, and a plurality of elastic detection probes 8 are respectively installed 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 platen 3, the insulating block 7, the insulating block 14, and the probe mounting plate 5 on which the elastic detection probe 8 can be insulated, the interference of the detection mechanism's own factors on the resistance detection of the coil 6 is effectively avoided.

[0031] At least the part of the clamping device that contacts the coil 6 is made of insulating material, and is used to clamp the coil 6 between the insulating pressing plate 3 and the probe mounting plate 5 in a fixed posture. Figure 4 As shown, in this embodiment, the coil 6 has two bent first contact lead pins 9 and second contact lead pins 10; the posture is that the ends of the contact lead pins are arranged 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 pin has a groove 13. One side of the coil 6 is convexly arranged outside the insulating pressure plate 3 to adapt to the first contact lead pin 9. Specifically, when the clamping device clamps the coil 6 in the 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 abuts against the skeleton on the upper side of the coil 6, and the insulating pressure block 7 abuts against the upper surface of the first contact lead-out pin 9 of the coil 6; the second drive 4 drives the probe mounting plate 5 to move upward, so that the first contact lead-out pin 9 and the second contact lead-out pin 10 are respectively inserted into the groove 13 of the head of the probe 11, and are pressed upward under the action of the spring 12 to be in a compressed abutment state, thereby ensuring the first contact lead-out pin 9 and the second contact lead-out pin 10 are in stable contact with the probe 11, thereby performing accurate and stable detection, greatly reducing the possibility of misjudgment.

[0033] It should be noted that, in this embodiment, since the bending part of the second contact lead pin 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 pin 10; and the bending part of the first contact lead pin 9 is far away from the coil 6, therefore, the insulating pressure block 7 is required to abut the upper side of the first contact lead pin 9, and then cooperate with the elastic detection probe 8 to achieve stable contact. In this example, the resistance detection of the six coils 6 can be carried out at the same time to ensure the detection efficiency; of course, in other embodiments, multiple coils 6 can be set for synchronous detection according to actual conditions.

[0034] Preferably, the insulating pressing block 7 can be movably connected to the insulating pressing plate 3 , so that the protruding height can be adjusted to adapt to different coils 6 .

[0035] The resistance test mechanism has a simple structure, occupies a small space, has wide applicability and strong compatibility. It can be widely used in automated production equipment, and can also be used in fully automated production lines in other fields such as components.
