Abstract
The utility model relates to a punch of a lithium tablet used in the productive process of a Li-Mn button cell, which is provided with a housing; a cam cavity is formed on the upper side in the housing; a cam driven by a stepping motor is arranged in the cam cavity; a travel cavity is formed below the cam cavity; a punching lever is arranged in the travel cavity; the top end of the punching lever tangentially contacts the cam; a punching head is arranged at the bottom end of the punching lever; a worm spring is arranged in the housing on the periphery of the travel cavity; and an extraction head of the worm spring is hinged in the punching lever. The punch is applicable to the automatic flow-line production of the Li-Mn button cell and can automatically conduct the punching procedure of the lithium tablet in the manufacture process after the operation cycle is already adjusted, and the operation is safe and effective.
Description
Technical field
The utility model relates to the lithium sheet stamping machine that uses in a kind of li-Mn button cell production process.
Background technology
Along with developing rapidly of electronic technology, present various electric equipments all are tending towards miniaturization significantly, and button cell is widely used as the power supply of portable electron device.Button cell has that volume is little, internal resistance is low, discharge voltage is stable, the advantage of long service life.Yet the production of button cell mostly still relies on workman's hand assembled to carry out at present, and operating personnel are many, and conformity of production is poor, and efficient is low, and battery quality is short of easily.In the production process of li-Mn button cell, the lithium sheet must strike out the circle sheet that covers bottom, negative electrode casing shell chamber after inserting negative electrode casing, and what adopt in present production technology is that foot-operated stamping machine is operated by hand, and efficient is low, poor stability.
The utility model content
The technical problems to be solved in the utility model is: for the shortcoming and the deficiency that overcome prior art, the utility model provides the lithium sheet that uses in a kind of li-Mn button cell production process stamping machine.
The technical solution adopted in the utility model is: the lithium sheet stamping machine that uses in a kind of li-Mn button cell production process, it has housing, upside is a cam chamber in the housing, be provided with cam driven by stepper motors in the cam chamber, the cam chamber below is the stroke chamber, and stroke is provided with punch rod in the chamber, the tangent applying of the top of punch rod and cam, the bottom of punch rod is provided with pressure head, is provided with the volute spring in the housing around the stroke chamber, and the leading-out end of volute spring is articulated in the punch rod.
For the suffered restoring force equilibrium that is provided by the volute spring of punch rod is provided, described volute spring is provided with 2 or 4 symmetrically in the housing around the stroke chamber.
The beneficial effects of the utility model are: this machine is applicable on the automation production flow line of li-Mn button cell, regulates the lithium sheet stamping procedure that can carry out automatically behind the operation period in the production process, running safety, efficient.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is a structural representation of the present utility model.
1. housings, 2. cams, 3. punch rod, 31. pressure heads, 4. volute springs among the figure
The specific embodiment
The lithium sheet stamping machine that uses in a kind of li-Mn button cell production process as shown in Figure 1, it has housing 1, upside is a cam chamber in the housing 1, be provided with cam 2 driven by stepper motors in the cam chamber, the cam chamber below is the stroke chamber, is provided with punch rod 3 in the stroke chamber, the top of punch rod 3 and cam 2 tangent applyings, the bottom of punch rod 3 is provided with pressure head 31, is provided with volute spring 4 in the housing 1 around the stroke chamber, and the leading-out end of volute spring 4 is articulated in the punch rod 3.
For the suffered restoring force equilibrium that is provided by volute spring 4 of punch rod 3 is provided, described volute spring 4 is provided with 2 or 4 symmetrically in the housing 1 around the stroke chamber.
Lithium sheet stamping machine of the present utility model is applicable on the automation production flow line of li-Mn button cell, regulates the stamping procedure that can carry out lithium sheet in the production process behind the operation period automatically, running safety, efficient.
