Description

Technical Field

[0001] The utility model relates to the field of terminal quality inspection, in particular to a terminal installation detection device. Background Art

[0002] Terminals are connectors located at the ends of wires, so connecting and assembling the terminals to the wires is an essential processing step.

[0003] Currently, the Chinese utility model patent application with application number 202421042384.9 discloses a wire harness terminal crimping device, including a terminal support body for supporting the terminal; a guide member, located above the terminal support body, and having a guide channel for the power supply line to pass through in an axial direction parallel to the terminal wiring groove; and a clamping assembly, which provides a clamping force on the wire located in the guide channel so that the wire is clamped into the terminal wiring groove.

[0004] The existing patent discloses a combination method of terminals and wires. In order to ensure the stability of electrical signal transmission, there are high requirements for the connection strength between the terminals and the wires. It is necessary to ensure that the wires are pressed into the terminals to a sufficient depth. Therefore, after the terminals and wires are assembled, it is necessary to conduct a quality inspection to ensure that the wires are buried deep enough in the terminals. Utility Model Content

[0005] The utility model aims to provide a terminal installation detection device, which has the advantage of being able to perform quality inspection on whether the depth of wire material embedded in the terminal is qualified.

[0006] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions: a terminal installation detection device, comprising:

[0007] A terminal carrier, used to carry the terminal;

[0008] A sliding plate, on which a probe is provided, wherein the probe slides relative to the sliding plate when under pressure;

[0009] a sliding drive member, driving the sliding plate to move quantitatively toward the position of the terminal carrier, the movement distance being equal to the distance from the end of the probe to the top position of the wire when the wire is embedded in the terminal to a sufficient depth; and

[0010] An in-place sensor and a controller are provided. The in-place sensor is triggered when the probe slides relative to the sliding plate and sends a signal to the controller. The controller determines that the terminal that triggers the in-place sensor is unqualified.

[0011] By the technical scheme, the terminal to be detected is placed on the terminal carrier, then the sliding driving element drives the sliding plate to slide, and then drives the probe to slide for a fixed distance, when the wire is embedded in the terminal for a sufficient length, the probe does not contact the wire, at this time, the in-place sensor is not triggered; when the embedding depth of the wire is insufficient, the wire blocks the sliding path of the probe, so that the probe is limited to slide relative to the sliding plate, and the in-place sensor is triggered when the probe slides, so that the controller obtains the information that the product is unqualified, thereby realizing quality inspection on the product.

[0012] In an embodiment of the present application, the sliding plate is fixed with a sliding rail, the length direction of the sliding rail is the same as the sliding direction of the sliding plate, the length direction of the probe is the same as the length direction of the sliding rail, the sliding plate is fixed with an abutting plate, and an elastic element is arranged between the abutting plate and the probe and applies an elastic force to the probe and points to one end of the terminal carrier.

[0013] By the technical scheme, the elastic element is used to make the probe retreat to the original position after moving relative to the sliding plate, and on the other hand, the elastic element applies an elastic force to the probe to relatively fix the probe and the sliding plate when the probe is not pressed.

[0014] In an embodiment of the present application, the elastic element is a spring.

[0015] By the technical scheme, the spring applies an elastic force to the probe.

[0016] In an embodiment of the present application, one side of the probe is spaced apart from a sliding element, the sliding direction of the sliding element is parallel to the sliding direction of the probe, the sliding element is driven by a connecting rod, the connecting rod is hinged to the sliding plate and the connection position is located on the side close to the probe, and the in-place sensor is triggered by the sliding element.

[0017] By the technical scheme, when the probe slides relative to the sliding plate, the connecting rod is rotated, the connecting rod drives the sliding element to slide, and because the rotating radius of the connecting rod at the connection end with the probe is smaller than the rotating radius of the connecting rod at the connection end with the sliding element, the sliding distance of the sliding element is greater than the sliding distance of the probe, so that the probe cannot trigger the in-place sensor due to too small sliding length, and the detection accuracy is improved.

[0018] In an embodiment of the present application, the two ends of the connecting rod are respectively provided with sliding grooves, the length direction of the sliding grooves is the same as the length direction of the connecting rod, and the probe and the sliding element are respectively fixed with fixed pins assembled in the sliding grooves.

[0019] By the technical scheme, the sliding grooves provide a displacement allowance when the connecting rod rotates.

[0020] In an embodiment of the present application, the sliding driving element is a servo system.

[0021] By the technical scheme, the servo system drives the sliding plate to quantitatively slide.

[0022] As described above, the terminal installation to position detection device has the following beneficial effects:

[0023] The terminal to be detected is placed on the terminal carrier, then the sliding driving member drives the sliding plate to slide, and further drives the probe to slide a fixed distance, the probe does not contact the wire when the wire is embedded in the terminal for a sufficient length, at this time, the in-place sensor is not triggered; when the embedding depth of the wire is insufficient, the wire will block the sliding path of the probe, so that the probe is limited to slide relative to the sliding plate, and the in-place sensor is triggered when sliding, so that the controller obtains the information that the product is unqualified, thereby realizing quality inspection on the product.
