Embodiment Construction
[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0026] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

The invention relates to a resistance test apparatus comprising a pedestal, a support part, a fixation mechanism, and a testing mechanism. The support part is arranged at the pedestal. The fixation mechanism consists of a lifting assembly, a fixation part, and a pressing and holding part; the lifting assembly is used for driving the fixation part to move away from or approach a support surface along a direction perpendicular to the support surface; and the pressing and holding part is used for compressing a product. The testing mechanism includes a probe fixation seat, a first drive element and at least two probes assembled to the fixation seat; the probe fixation seat is connected to onside, facing the support surface, of the fixation part movably; the at least two probes extend relative to the support surface in different directions; the first drive element is arranged at the other side, far away from the support surface, of the fixation part and is capable of driving the corresponding probe fixation seat to move along a preset direction. Compared with the traditional resistance test apparatus, the resistance test apparatus provided by the invention is capable of detecting detection positions of a plurality of surfaces simultaneously, thereby saving the man power and time and improving the testing efficiency.
Description
technical field [0001] The invention relates to the technical field of resistance testing, in particular to a resistance testing device. Background technique [0002] In the manufacturing process of the middle frame of electronic products such as mobile phones and tablet computers, in order to facilitate the subsequent installation of circuit boards and other electronic components, it is usually necessary to arrange metal parts along the inner wall of the middle frame to facilitate the installation and fixing of circuit boards and electronic components. on metal parts. At the same time, in order to play the role of grounding protection, the circuit board and / or electronic components are conductively connected to the metal sheet, but the change of resistivity at the connection has also become an important factor affecting the performance parameters of electronic products. Therefore, after connecting the metal part to the middle frame, it is necessary to detect the resistivit...
