Fig. 1 is a schematic structural diagram of a module voltage rapid measurement apparatus provided in an embodiment of the present invention;

FIG. 2 is a schematic structural diagram of the module voltage rapid measurement apparatus shown in FIG. 1;

the labels in the above figures are: 1. the probe comprises a frame, 11, reinforcing ribs, 2, a probe board, 21, a probe, 3, an end limiting block, 4, a side limiting block, 5, a handle, 6 and a pressing plate.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a module voltage rapid measurement apparatus includes:

a frame; the probe card, there are a series of probe cards on the frame, the probe card is installed on frame slidably; the frame is the aluminium alloy frame for the lock of probe card attaches, and its advantage is that the probe card can slide wantonly in aluminium alloy length direction, through the position of adjusting the probe card, the module product of the convenient compatible different length of quick measuring device of voltage in time, through increasing or reducing the quantity of probe card, also can be the product that the device can be compatible different electric core quantity.

A probe mounted on the probe card, the probe being capable of contacting the battery electrode; the tail end of the probe is provided with a circuit; the probe board is used for connecting the probe and the profile frame, is processed by adopting a glass fiber material with excellent insulating property, and can effectively prevent the interference to the voltage test; meanwhile, the discrete probe card design replaces the whole probe card, so that the compatibility of different products can be facilitated. The probe uses the higher 4mm diameter probes of intensity, can deal with staff's error and cause the probe damage, improves holistic life of frock and stability.

The end limiting blocks are arranged at two ends of the frame and can limit two ends of the battery module; and the side limiting blocks are arranged on two sides of the frame and can limit two sides of the battery module. The positioning block is used for positioning the tool and the module in a large scale range, the positioning block is designed in an imitated mode, operation of workers can be facilitated, the positioning block is higher than the probe in design height, a supporting effect can be achieved when the tool is not used, the probe is prevented from directly falling to the ground, the head of the probe is prevented from being polluted, and interference is caused to follow-up voltage testing.

The probe is also provided with a pressing plate, the pressing plate is arranged on the frame, and the pressing plate is arranged on the back surface of the probe. For transparent ya keli, the probe has certain resilience force in the course of the work, and the probe on the whole frock is in a large amount, and its holistic resilience force is great, increases the weight of frock through design yakeli, guarantees that the frock in the course of the work the probe all the time with the product contact well, for make the staff can be quick place the product with the frock through the stopper on, design into transparent mode with yakeli, do benefit to the observation more.

The frame is provided with a reinforcing rib. The special reinforcing rib for the aluminum profile has the function of preventing the aluminum profile in the length direction from rotating and causing interference to the measurement of the battery cell. The frame is provided with a handle which is convenient to hold.

The probe card that can one-man operation carries out semi-automatic acquisition, places the probe card on the module product through the staff is manual, makes probe and product contact, and rethread host computer control tester carries out voltage acquisition to the probe one by one, realizes high-efficient voltage acquisition.

1. The operation is convenient: the operation can be completed by a single person, and the operation mode is simple;

2. the efficiency is high: the tool replaces the cooperation of two operators and is operated by a single person, so that the operation efficiency is greatly improved;

3. the stability is high: compared with manual measurement of a single person, the probe is in a static state in the test process by using the tool, so that voltage acquisition and measurement of a voltage tester are facilitated;

4. the universality is strong: the tool can quickly adapt to voltage measurement of different module products by moving the position of the probe board and increasing or reducing the number of the probe boards.

After adopting foretell structure, convenient operation, single can accomplish the operation, and the operation mode is simple, can adapt to the voltage measurement of different module products fast through the position of removing the probe card and increase or reduce the quantity of probe card.
