A kind of automatic tin adding mechanism
Technical field
The present invention relates to photovoltaic product, be specifically related to a kind of automatic tin adding mechanism in a kind of photovoltaic welding belt tin equipment.
Background technology
Along with the development and progress of society, automatization, integration have progressively become the trend of development, and manual labor, traditional mode of operation have progressively been updated superseded.
By the tin-coated welding strip that cell piece series connection uses in solar photovoltaic assembly, need through tin stove when tin-coated welding strip is produced on equipment, copper strips is coated with tin through tin stove and forms welding.Traditional tin mode that adds is calculate the quantity of added tin within a certain period of time in zinc-plated process according to welding rice number.Such mode has following shortcoming: the product specification specifications vary of 1, producing is frequent, and production operation person can not adjust in time to adding tin quantity, and tin stove liquid level will be caused to be in relative unsteady state.2, due to the instability of liquid level in tin stove, the uneven thickness of institute's tin coating in zinc-plated process will be caused, increase product and to do over again quantity.3, just adding in for some time of tin, because tin bar needs to melt, causing local temperature in tin stove to reduce, causing tin coating uneven thickness equally, the quantity thus increase product is done over again.
Summary of the invention
The object of the present invention is to provide a kind of have make homo(io)thermism in tin stove, tin liquor height relatively stable, reduce manpower and reach automatization effect, improve the automatic tin adding mechanism of conforming product rate.
Technical scheme of the present invention is, a kind of automatic tin adding mechanism, zinc-plated for photovoltaic welding belt, fixed support, tin bar storing unit, temperature sensing device, lifting groove and regulating and controlling device, described fixed support is arranged at above tin stove, described tin bar storing unit, lifting groove and regulating and controlling device are arranged at fixed support inside, and described regulating and controlling device is arranged at tin bar storing unit side, and described temperature sensing device is arranged in the tin liquor in tin stove.
In a preferred embodiment of the present invention, described tin bar storing unit afterbody and tin liquor contact position are provided with tin bar retaining groove.
In a preferred embodiment of the present invention, described tin bar storing unit is square shape pipeline, and pipe shaft is provided with manhole.
In a preferred embodiment of the present invention, described lifting groove is I-shaped structure.
In a preferred embodiment of the present invention, described lifting groove is arranged between fixed support and tin bar storing unit.
In a preferred embodiment of the present invention, described regulating and controlling device comprises automatic tin adding stop button, adds tin set of time button and temperature monitoring point button.
Of the present invention is a kind of automatic tin adding mechanism, the present invention carries out liquid level in observation tin stove with temperature inductor and temperature difference transmitter, thus accurately can ensure that the height of tin liquor in tin stove remains on stable state, reduce the effect that manpower reaches automatization, the rework rate of further reduction product, improves the qualification rate of product.

Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Of the present invention is a kind of automatic tin adding mechanism, shown in Figure 1, zinc-plated for photovoltaic welding belt, fixed support 1, tin bar storing unit 2, temperature sensing device 3, lifting groove 4 and regulating and controlling device 5, described fixed support 1 is arranged at above tin stove, it is inner that described tin bar storing unit 2, lifting groove 4 and regulating and controlling device 5 are arranged at fixed support 1, and described regulating and controlling device 5 is arranged at tin bar storing unit 2 back, and described temperature sensing device 3 is arranged in the tin liquor in tin stove.
Described tin bar storing unit 2 afterbody and tin liquor contact position are provided with tin bar retaining groove 6.
Described tin bar storing unit 2 is square shape pipeline, and pipe shaft is provided with manhole.
Described lifting groove 4 is in I-shaped structure, and described lifting groove 4 is arranged between fixed support 1 and tin bar storing unit 2.
Shown in Fig. 1 composition graphs 2, described regulating and controlling device 5 is cylinder and automatic tin adding sequence check switch and setting device, comprises automatic tin adding stop button 7, adds tin set of time button 8 and temperature monitoring point button 9.
Automatic tin feeding device is fixed on tin machine refrigerating unit, required tin bar is stored in tin bar storing unit, described temperature sensing device comprises temperature inductor and temperature difference transmitter, described lifting groove can according to regulating and controlling device perform fast and accurately add tin time tin bar storing unit needed for the height that keeps.
When using this tin bar storing unit, many tin bars can be put in tin bar storing unit, can reduce and manually add tin frequency, temperature sensing device can accurately sense tin surface temperature, lifting groove accurately can control the spacing of tin bar storing unit and tin liquor, thus tin stove liquid level is kept relative stability state, improve the quality of products.
Automatic tin adding trip switch and setting device, can start or stop control according to individual Man's Demands to its automatic tin feeding device, on the apparatus to adding the tin time and temperature detecting point regulates, namely achieving automatization, not losing its handiness again
Of the present invention is a kind of automatic tin adding mechanism, the present invention carries out liquid level in observation tin stove with temperature inductor and temperature difference transmitter, thus accurately can ensure that the height of tin liquor in tin stove remains on stable state, reduce the effect that manpower reaches automatization, the rework rate of further reduction product, improves the qualification rate of product.
The foregoing is only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
