Automatic silk-screen detection equipment for positive electrode plate of PTC (Positive Temperature Coefficient) heater

Abstract

The invention discloses PTC heater positive electrode slice automatic silk-screen detection equipment which comprises an automatic feeding mechanical arm, an automatic silk-screen mechanism, a visual detection mechanism and an automatic discharging mechanism which are arranged around a rotating disc carrying mechanism according to the working procedure sequence, and the rotating disc carrying mechanism is provided with a positive electrode slice positioning clamp used for sequentially conveying positive electrode slices according to the working procedure; the automatic feeding mechanical arm carries a positive electrode slice in the positive electrode slice storage mechanism into a positive electrode slice positioning clamp in the rotating disc carrying mechanism, the automatic screen printing mechanism carries out screen printing on the positive electrode slice, and a visual identification lens is arranged in the visual detection mechanism to detect whether screen printing of the positive electrode slice is qualified or not. The automatic discharging mechanism is used for taking out the positive electrode plates from the positive electrode plate positioning clamp, placing unqualified products in a defective product box, placing qualified products in a transferring tool and conveying the qualified products to the next working procedure. The automatic screen printing and detection production efficiency is high, the screen printing quality is consistent and stable, and the large-batch production requirement can be well met.

Description

technical field [0001] The invention relates to the technical field of production equipment for new energy components, in particular to an automatic screen printing detection device for a positive electrode sheet of a PTC heater. Background technique [0002] PTC heater is an efficient heater with good thermal conductivity, uniform temperature, long life, strong mechanical properties and corrosion resistance. New energy vehicles need to use PTC heaters as heat sources. With the continuous development of the new energy vehicle market, the use of PTC heaters is increasing. [0003] When manufacturing PTC heaters, it is necessary to screen-print the surface of the positive electrode sheet, and after the screen-printing, it is necessary to detect the unqualified products of the screen-printing, and the qualified products are transported to the next process. Due to the small number of PTC heaters required in the market in the past few years, there is currently a lack of automate...

AI Technical Summary

Problems solved by technology

Due to the small number of PTC heaters required by the market in the past few years, there is currently a lack of automated equipment for large-scale silk screen printing on the surface of the positive electrode of the PTC heater. At present, it is basically semi-automatic to place the positive electrode on the screen printing machine manually. Production, after silk screen printing, it needs to be removed manually for inspection, the production efficiency is low, and it cannot meet the requirements of mass production
