The testing mechanism 18 includes a probe fixing base 184, a first driving member 186 and at least two probes 188 mounted on the probe fixing base 184, the probe fixing base 184 is movably connected to one side of the fixing portion 164 facing the supporting surface 142, and the at least two probes 188 extend in different directions relative to the supporting surface 142. The first driving member 186 is disposed on the other side of the fixing portion 164 away from the supporting surface 142 and can drive the corresponding probe fixing seat 184 to move along a predetermined direction.
in practical applications, a product is placed on the supporting surface 142, and the lifting assembly 162 drives the fixing portion 164 to descend so that the pressing portion 166 presses the product when reaching a predetermined position. At this time, the probe 188 is not in contact with the product, and then the first driving member 186 drives the probe fixing seat 184 to move along a predetermined direction to reach a certain position, so that the probe 188 reaches a corresponding detection position for detection. Therefore, the probe 188 is installed and extended in different directions according to different detection positions of the product, and the first driving member 186 drives the probe fixing seat 184 to move to a corresponding position, so that the probe 188 can reach the corresponding detection position, thereby completing the detection. Compare traditional resistance testing arrangement, can detect the detection position of a plurality of faces simultaneously, saved manpower and time, improved efficiency of software testing.
It should be noted that at least two probes 188 extending in different directions relative to the supporting surface 142 may be mounted on one probe holder 184 or different probe holders 184, in short, the purpose of simultaneously testing multiple surfaces by at least two probes 188 can be achieved.
In one embodiment, the testing mechanism 188 includes at least one testing component, each testing component includes a probe fixing seat 184, a first driving member 186 and a plurality of probes 188, the probe fixing seat 184 is movably connected to a side of the fixing portion 164 facing the supporting surface 142, and the plurality of probes 188 are installed on the probe fixing seat 184 in different directions relative to the supporting surface 142. Specifically, the probe fixing seat 184 is provided with mounting positions 1842 for the probes 188 to be mounted in different directions toward the supporting surface 142, and the first driving member 186 is disposed on the other side of the fixing portion 164 away from the supporting surface 142 and can drive the corresponding probe fixing seat 184 to move along a predetermined direction.
It should be understood that, since there are multiple test sites for different products, and the multiple test sites may be distributed on one or more sides of the product, in an actual test, at least one set of test modules may be provided, and the extending direction of the probes 188 in each set of test modules toward the supporting surface 142 is set according to the distribution position of the test. The displacement of the probe fixing seat 184 is controlled by the first driving member 186 in each set of test components, so that the probe 188 just reaches the detection position to realize the detection. For example, in one embodiment, as shown in fig. 1, the product is a middle frame of a mobile phone, the detection positions are disposed at positions close to two ends of the inner cavity of the product and are respectively located at the bottom wall, the side wall and the corner where the side wall is connected to the side wall of the inner cavity of the product, and the test assemblies include three sets.
In one embodiment, the probe holder 184 includes a detecting position, the first driving member 186 drives the probe holder 184 to move in a predetermined direction to terminate at the detecting position, and the probe 188 contacts the detecting position on the product. That is, when the pressing portion 166 presses the product against the supporting surface 142, the first driving member 186 drives the probe fixing seat 184 to move by a predetermined displacement, and when the probe fixing seat 184 is terminated at the aforementioned detection position, the probe 188 just contacts with the detection position of the product, so as to ensure the normal operation of the detection.
In one embodiment, referring to fig. 3 and 4, the fixing portion 164 is provided with a sliding slot 1642 along a predetermined direction, the probe fixing base 184 includes a body portion 1843 and a sliding portion 1844 connected to the body portion 1843, the body portion 1843 is provided with the aforesaid mounting position 1842, and the sliding portion 1844 extends into the sliding slot 1642 and is connected to the first driving member 186 to move along the sliding slot 1642 under the driving of the first driving member 186. Thus, through the arrangement of the sliding slot 1642 and the sliding portion 1844, the probe fixing seat 184 and the first driving member 186 can be respectively disposed at two opposite sides of the fixing portion 164, so as to facilitate the disposition of the first driving member 186, and prevent the first driving member 186 from contacting with a product to damage the product.
in one embodiment, the fixing portion 164 is plate-shaped, and the testing assemblies include three sets, two sets of testing assemblies disposed in parallel in the transverse direction are used for testing the detection positions of the bottom wall and the side wall at the two ends of the inner cavity of the product, and one set of testing assemblies disposed in the longitudinal direction are used for testing the detection positions at the corner where the side wall and the side wall of the inner cavity of the product are connected. Correspondingly, the slide grooves 1642 include three, including two along the longitudinal direction of the fixing portion 164 and one along the width direction of the fixing portion 164.
It should be understood that the slide 1642 is configured to not only enable the probe fixing seat 184 to move along a predetermined direction, but also function as a limit. That is, the end wall of the sliding groove 1642 can limit the sliding portion 1844, i.e., the probe fixing seat 184, during the process of moving the sliding portion 1844 along the sliding groove 1642 toward the end of the product.

One end of the mating portion 1846 extends out of the sliding slot 1642 and is coupled to the output end of the first driving member 186. Therefore, the probe fixing seat 184 is conveniently connected with the output end of the first driving member 186, the probe fixing seat 184 is conveniently disassembled, and the moving stability of the probe fixing seat 184 is ensured.
it should be understood that if the mating portion 1846 is not provided, the sliding portion 1844 would need to extend out of the sliding slot 1642 to mate with the output end of the first driving member 186 when the probe fixing seat 184 is installed. The gravity of the probe fixing base 184 is borne at the coupling position of the sliding portion 1844 and the output end of the first driving member 186, and the output end of the first driving member 186 is damaged and fails over time. In one embodiment, the engaging portion 1846 is fixed on one side of the sliding portion 1844 and extends out of the sliding slot 1642, so that the gravity of the probe fixing seat 184 is transferred between the engaging portion 1846 and the fixing portion 164. Therefore, the arrangement of the engaging portion 1846 can ensure the stable connection between the first driving member 186 and the sliding portion 1844, and ensure the stability of the movement of the probe fixing seat 184. In another embodiment, the width of the engaging portion 1846 is set to be larger than the width of the sliding groove 1642, so that the gravity of the probe fixing base 184 can be transferred between the engaging portion 1846 and the fixing portion 164, thereby ensuring the reliability of the connection between the probe fixing base 184 and the output end of the first driving member 186 and the stability of the movement of the probe fixing base 184.
