Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of detecting the total thickness of the bottom wall and sleeve of a combined part, and particularly relates to a combined part total thickness detection device. BACKGROUND

[0002] The structure of a certain combined part is shown in the figure, which comprises a sheet 1 and a sleeve 2. Figures 1-2 The closed end of the sleeve 2 is welded to the top surface of the sheet 1. This combined part is generally used for installation in a certain electronic product. When a batch of combined parts are produced in the workshop, the total thickness H of the bottom wall of the sleeve 2 and the sheet 1 of the combined part needs to be detected, and unqualified products are removed at the same time.

[0003] The method for detecting the total thickness of the combined part in the workshop is as follows:

[0004] S1, the worker takes out a combined part to be detected from the basket, and holds the sleeve 2 of the combined part with his hand;

[0005] S2, the worker measures the total thickness H of the bottom wall of the sleeve 2 and the sheet 1 of the combined part with a caliper. If the detected total thickness H is not within the design range, the worker determines that the detected combined part is unqualified, and then removes the unqualified product. If the detected total thickness is within the design range, the worker determines that the detected combined part is qualified, and the worker puts the qualified product into the finished product basket, thereby completing the detection of the total thickness of one combined part.

[0006] S3, the worker repeats the steps S1-S2, thereby continuously detecting the total thickness of multiple combined parts.

[0007] However, although the method used in the workshop can detect the total thickness of the combined part, there are still the following technical defects in actual operation:

[0008] In step S2, after the worker measures the total thickness of the combined part with the caliper, he needs to manually judge whether the measured total thickness is within the design range, which not only increases the work intensity of the worker, but also increases the detection time of the total thickness of a single combined part, thereby reducing the detection efficiency of the total thickness of the combined part.
