Abstract
The invention relates to a laser irradiator, especially relating to a laser head on the laser irradiator. A technical scheme of the invention is as follows: the laser head comprises a head shell and a lens and is characterized in that: outer peripheral face of the lens is provided with screw thread which is in one body with the lens, and the lens and the head shell are in rotating connection through the screw thread. By employing the above scheme, problems in the prior art are overcome, and the invention provides a novel laser head with simple structure and convenient installation.
Description
Technical field
The present invention relates to a kind of laser irradiation device, be meant the laser head on the laser irradiation device especially.
Background technology
The structure of the laser head of existing laser irradiation device is following, includes head capsule, conflict fixed head or spring, lens and set bolt, and the fixed head of wherein conflicting is crossed to win and is arranged in the head capsule or screw thread is arranged in the head capsule; Lens are arranged on the conflict fixed head then, are fixed on lens between the conflict fixed head and bolt of head capsule through set bolt at last, and the laser head structure of this structure is very loaded down with trivial details; It is very inconvenient to take dress in addition; Particularly the lens direction be provided with very difficultly, be easy to occur mistake, wasted manpower and unable greatly; Improved production cost of products virtually, focusing is also pretty troublesome at last.
Summary of the invention
The present invention overcomes the problem that prior art exists, and provides a kind of simple in structure, novel laser head easy for installation.
Realize above-mentioned purpose, the present invention adopts following technical scheme: a kind of laser head, include head capsule and lens, it is characterized in that, on the outer peripheral face of said lens with it one be provided with screw thread, spin through screw thread between lens and the head capsule.
Through adopting such scheme, the present invention can directly be screwed in lens on the head capsule through screw thread, and is so very simple and convenient, also need not consider the direction of lens in addition, saves the time of installing greatly, and can realize the machine installation.
Further setting of the present invention is: said lens include the threaded portion, reverse forced section and light collecting part; Wherein the threaded portion with reverse forced section and constitute a bolt with cylindrical cavity; Described light collecting part places the middle part of cylindrical cavity, said threaded portion, reverses forced section and light collecting part is wholely set; The convex surface of said lens light gathering portion is towards reversing forced section, and the said outer peripheral face that reverses forced section is that polygon or the said end of reversing forced section are provided with a word or cross recess.
The purpose that further is provided with is, takes into full account to set on the basis of properties of product superiority, and wherein the light collecting part middle part that is arranged on cylindrical cavity can play a protective role, and the type selecting of reversing forced section in addition is to make as required.
Of the present invention further the setting again is: also include laser circuit board and circuit board fixing rack; Described circuit board fixing rack is arranged in the head capsule; Described circuit board is arranged on the circuit board fixing rack, and described circuit board is a monoblock, and the front end of circuit board directly is set with laser chip; On the positive and negative that is positioned at laser chip portion of one monoblock circuit board with it one be provided with fin, said circuit board fixing rack and head capsule are wholely set.
The purpose that further is provided with again is, takes into full account to set on the basis of properties of product superiority, and such in addition circuit board volume is little, easy for installation.
Below in conjunction with accompanying drawing the present invention is further described.
