Abstract
The utility model relates to a kind of coating process defects detection protective device; described protective device is light curtain; described light curtain is placed in extrusion coating machine outlet pole piece place; described light curtain is covered by pole piece; described pole piece upper end is the infrared emitting end be connected with extrusion coated machine controller; described pole piece lower end is the infrared receiver end be connected with extrusion coated machine controller; described infrared emitting end and infrared receiver end are oppositely arranged and align; the utility model structure is simple; the defect of pole piece is detected by light curtain, and and alarm feed back signal to the control system of coating machine.
Description
Technical field
The utility model belongs to field of lithium ion battery, is specifically related to coating defects in a kind of lithium ion battery preparation process and detects and protective device.
Background technology
From 1991; the invention of Sony Corporation of Japan has developed lithium rechargeable battery and since commercialization; lithium ion battery development rapidly; its range of application expanding day; occupation rate of market improves day by day; particularly along with arrival and the environmental pressure expanding day of energy crisis, lithium ion battery is applied on electric automobile as power source, and the demand of market to lithium ion battery is expanded further.Meanwhile, lithium ion battery manufacturer also gets more and more, and it is very fierce to compete, so how to reduce costs under the prerequisite ensureing the quality of production, becomes the main target that each enterprise is pursued.
In the extrusion coater course of work, have an interval between coater head and pole piece, this interval is very little, suitable with the thickness of coating.If pole piece is smoothly complete, then coating work can normally carry out; If pole piece has salient point, and its size exceedes the distance between coating machine discharging opening and pole piece, then cause coating pole piece to tear, thus need to stop painting process.At present this process is omnidistance all by manual detection, and the phenomenon such as not in time easily occurs to find, thus causes pole piece to tear even to rupture, reduce whole coating efficiency, waste material.
Utility model content
In order to make up prior art problem, the purpose of this utility model is to provide a kind of coating process defects detection protective device, can detect the defect of pole piece, and and alarm feed back signal to the control system of coating machine.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of coating process defects detection protective device, described protective device is light curtain, and described light curtain is arranged on extrusion coating machine outlet, and described light curtain is covered by pole piece.
Further, described pole piece upper end is the infrared emitting end be connected with extrusion coated machine controller, and described pole piece lower end is the infrared receiver end be connected with extrusion coated machine controller, and described infrared emitting end and infrared receiver end are oppositely arranged and align.
Further, described light curtain is perpendicular to pole piece.
Further, described light curtain support size equals the width of pole piece.
The beneficial effects of the utility model:
1) pole piece defect can be detected, prevent bad pole piece from entering subsequent processing;
2) if pole piece occurs that defect can stop in time and report to the police, decrease because finding the loss caused not in time;
3) machine detects automatically, automatic alarm, alleviates coating workman workload, it can be made simultaneously to carry out multinomial work.
Accompanying drawing explanation
Fig. 1 is the utility model coating process defects detection protective device schematic diagram.
In accompanying drawing: 1, light curtain, 2, infrared emitting end, 3, infrared receiver end, 4, pole piece.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, a kind of coating process defects detection protective device, described protective device is light curtain 1, and described light curtain is placed in extrusion coating machine outlet pole piece 4 place, and described light curtain 1 is covered by pole piece 4.
Wherein, described pole piece 4 upper end is the infrared emitting end 2 be connected with extrusion coated machine controller, described pole piece 4 lower end is the infrared receiver end 3 be connected with extrusion coated machine controller, described infrared emitting end 2 and infrared receiver end 3 are oppositely arranged and align, conveniently detect, described light curtain 1 is perpendicular to pole piece 4.
Described light curtain 1 support size equals the width of pole piece 4, is guaranteed at inspection time difference method.
Light curtain 1 is opened when painting process carries out, if there is light leakage phenomena in pole piece 4, as damaged, defect, then light curtain 1 feeds back signal to the control device of coating machine by holding wire and gives the alarm, thus coating machine is stopped in time, the then fault that occurs of hand inspection, and according to circumstances immediate correction, thus ensure the quality of producing product, and the loss that defect is brought is tending towards minimizing.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
