Automatic testing mechanism for soft package lithium battery and equipment

Abstract

The invention discloses an automatic testing mechanism for a soft package lithium battery and equipment. The testing mechanism comprises the components of an installing platform; a first fixing assembly and a second fixing assembly which are arranged on the installing platform; probe pressing modules which are arranged on the installing platform; and a driving mechanism which is arranged on the installing platform. Two sets of probe pressing modules are arranged. Furthermore each set of probe pressing module is provided with an anode tab holder and a cathode tab holder. The probe pressing module is connected with a preset movement track through a linear bearing. Furthermore the clamping cylinder in the two sets of probe pressing modules is controlled by one air inlet pipe, thereby controlling the two sets of probe pressing modules to test the soft package lithium battery simultaneously. The testing mechanism is compatible with a single-side outlet tab battery and a double-side outlet tab battery, thereby improving practicability of the testing mechanism. Furthermore simultaneous clamping of an anode probe holder and a cathode probe holder can be realized, thereby realizing higher clamping accuracy. Furthermore the probe pressing modules according to the invention can realize smooth motion and improves testing precision.

Description

technical field [0001] The invention relates to the technical field of lithium battery testing, in particular to an automatic testing mechanism and equipment for a soft-pack lithium battery. Background technique [0002] Nowadays, with the development of microelectronics technology, miniaturized devices are increasing day by day, thus putting forward high requirements on power supply. Lithium batteries are exquisite and convenient and have charge and discharge functions, so they have entered a large-scale practical stage. Lithium battery testing equipment is an indispensable part of battery production. [0003] However, most of the existing lithium battery test equipment can meet the test of a single type of soft-pack lithium battery, either a single-side tab lithium battery or a double-side tab-out lithium battery, which cannot be compatible with two types of lithium batteries at the same time. The probe crimping module in some lithium battery test equipment is directly d...
