Scraping machine and non-material testing apparatus

Abstract

The present invention relates to a scraper and a non-material detecting device on the scraper. The non-material detecting device comprises the following components: a photoelectric bracket which is fixed on the panel of the frame of the scraper and is installed with a photoelectric detecting element whereon; the photoelectric detecting element comprising a photoemitter and a photoelectric receiver; a rotating axis rotatablely traverses the panel and radially fixed with the panel, the rotating axis which is installed with a photoelectric detecting piece at one end near the photoelectric bracket, and is permanently fixed with a dwang at the other end; the dewang which is permanently connected with a fixed block which is perpendicular to the rotating axis and the dwang at the other end; a fixed block with one end connected with the transmission rod and the other end connected to a rotating head; the rotating head which is laid on the external circumstantial surface of the scraper material-laying coil with the gravity force; the position of the photoelectric detecting piece corresponding with no-material condition of the material-laying coil is between the photoelectric receiver and the photoemitter; and a controller which can control the scraper component to switch off the electric power source when a photoelectric detecting piece is detected by the photoelectric detecting element. The non-material detecting device can timely and accurately detect the material condition of the material-laying coil.

Description

technical field [0001] The invention relates to the field of lithium battery production, in particular to a scraper machine for cleaning the coating layer of welding points of tabs of lithium batteries and a material-free detection device on the scraper machine. Background technique [0002] Lithium batteries are mainly welded with tabs by the pole piece, then wound into a battery core by a winding machine, and the battery core is processed and put on a casing to form a finished product. The Chinese invention patent application whose document number is CN101114705 discloses a scraper machine. See Figure 1 and figure 2 , a scraper machine, comprising a feeding mechanism 1, a first tension control mechanism 2, four scraper mechanisms 3, an active pole piece traction mechanism 4, a second tension control mechanism 5, a material receiving mechanism 6 and a frame 9; Along the direction of the pole piece 7 from the discharging mechanism 1 to the receiving mechanism 6, the discha...

Problems solved by technology

[0007] The scraper machine with the above structure does not have a device for detecting the use of the pole piece on the unwinding reel. When there is no material (pole piece) on the unwinding reel, the whole machine will not stop automatically, but continues to pull the unwinding reel, resulting in a huge The noise will also cause damage to the entire machine
