When the push rod 21 reaches the predicted position of the product and the driving device 22 continues to apply the pushing force, the spring member 30 continues to be compressed until the cold joint is detected or the pushing force applied by the driving device 22 reaches a preset value. When the push rod 21 breaks at the position where the push rod 21 pushes the product, the elastic member 30 tends to return to the shape before being compressed, and the elastic force thereof pushes the push rod 21 forward, so that the push rod 21 is displaced. Whether the product is cold welded or not can be judged by observing or detecting whether the push rod 21 is displaced or not through other mechanisms. The production efficiency and the judgment accuracy of the false soldering can be improved, the error of manual detection is avoided, and the yield of products leaving the factory is improved.

Specifically, the push rod 21 and the push rod channel are connected through the guide sleeve 70, so that the service life of the push rod 21 can be effectively maintained, and the moving path of the push rod 21 is more stable.
In the present embodiment, the cross-sectional area of the push rod 21 gradually decreases in a direction away from the elastic member 30.
Specifically, at present, 3C products pay more attention to product refinement, on one hand, adaptability of the push rod 21 and the product needs to be considered, and on the other hand, the smaller the contact area between the push rod 21 and the product is, the more accurately the position of the cold joint of the product can be detected. The cross-sectional area of the end of the push rod 21 near the driving device 22 should be larger, so that the force transmission area can be increased, the force transmission is more stable, and the connection reliability of the push rod 21 and the connecting body 40 can be enhanced.

The manual workload and the working difficulty are reduced, and the accuracy of the computer is higher than that of manual judgment.
More specifically, when the product is positioned in the product positioning mechanism 10, the computer program gives an instruction, the driving device 22 pushes the product, the push rod 21 of the pushing mechanism 20 pushes the product accurately on the predicted position of the product, if the product has no cold joint, the pushed part does not deviate, the corresponding push rod 21 does not displace forward, the compression amount of the elastic piece 30 arranged in the pushing mechanism 20 is unchanged, and the sensor 80 outputs the set pressure to feed back to the equipment to judge that the product has no cold joint; when the product has the rosin joint, under the action of the thrust, the pushed part of the product is deviated or falls off, the compression amount of the elastic piece 30 arranged in the thrust mechanism 20 is released, and the output of the sensor 80 is smaller than the set pressure and is fed back to the equipment to judge the rosin joint of the product. With this design, the automatic auxiliary detection of the cold joint can be realized.
According to the cold joint detection jig provided by the utility model, the part to be detected of the product is limited at one end of the through groove 11 of the product positioning mechanism 10, the push rod 21 is pushed by the pushing mechanism 20 from the other end of the through groove 11 to be contacted with the part to be detected of the product, and the preset pushing force is applied to the part to be detected of the product.

The push rod 21 is connected with the driving device 22 through the elastic piece 30, when the driving device 22 pushes the push rod 21, the elastic piece 30 is compressed, and when the pushing force of the push rod 21 is within a preset value range and the product is inferred, the welding of the product is failed. After the product is disconnected, the front end of the push rod 21 is no longer subjected to resistance, and the elastic member 30 at the rear end of the push rod 21 has a state before restoring compression, and the elastic force thereof pushes out the push rod 21. Whether the product is cold soldered or not can be determined by detecting whether the push rod 21 is displaced after the push rod 21 is applied to the product by the push rod 20.
