Problems solved by technology

[0004] Two-time clamping is easy to cause clamping error, resulting in misalignment of double-sided cutting;
[0005] The repeated positioning accuracy of the workbench is not enough, and it will also lead to the misalignment of double-sided cutting when turning over and cutting;
[0006] If the materials on both sides of the workpiece to be processed are different, using the same laser may cause excessive damage to the processed part

Embodiment 1

[0036] Example 1: Such as Figure 5 As shown, a laser double-sided synchronous processing system has a middle displacement worktable 5, a left laser processing machine 7, a right laser processing machine 8, and the middle displacement worktables 5 and 6 are X and Y moving worktables perpendicular to each other. , X mobile workbench and Y mobile workbench are connected by guide rails, lead screws, motors and control devices to form X and Y position moving devices. X mobile workbenches and Y mobile workbenches form a T-shaped structure. A clamping fixture is fixed on the upper Y movable table. The left laser processing machine 7 is installed on the left side of the middle table 5, the right laser processing machine 8 is installed on the right side of the middle working table 5, and the left and right laser processing machines are The laser beam outputs of 7 and 8 all point to the middle worktable, and the laser beam of the left laser processing machine 7 and the laser beam axis of...

Embodiment 2

[0043] The left and right laser processing machines 7 and 8 are powered by two independent laser power supplies. At the same time, two chillers are used to cool the left and right laser processing machines 7 and 8 to a certain temperature range to ensure the continuous and stable operation of the laser.

[0044] The light guide focusing system is directly connected to the laser output end of the laser through the light path transition device, and a CCD monitoring system coaxial with the laser light path is installed on the light guide focusing system;

[0045] The structure of CCD monitoring system is as Figure 7 It mainly includes a laser focusing lens 29, an imaging focusing lens 22, a reticle (scored glass sheet) 23, a camera 22, a display 21, etc., and the monitor 21 is connected to the camera 20 by a line. The monitored position of the processed workpiece 4 is generally near the laser focal point and centered on the laser focal point. The reflected visible light on the surfac...

Embodiment 3

[0050] Embodiment 3: A laser double-sided synchronous processing method, by using two laser generators, or using a beam splitter to split the laser beam of the same laser into two beams to obtain two laser beams, such as Figure 4 As shown, the energy ratio of the two beams can also be adjusted by using different dichroic prisms.

[0051] Use necessary devices, such as optical fiber transmission or mirror turning, and adjust the laser collimation to make the two laser beams face each other and on the same straight line;

[0052] Install the focusing lens on the two laser beam paths, and ensure that the focusing lens is perpendicular to the laser beam and the center of the beam coincides with the center of the focusing lens through a two-dimensional adjustment piece;

[0053] Through adjustment, the plane of the two-axis movement direction of the two-dimensional platform is strictly perpendicular to the direction of the laser beam or at a required tilt angle;

[0054] Install the toolin...

Abstract

The invention discloses a laser double-faced synchronous machining system and a machining method thereof. The system comprises a laser, a middle displacement platform and a machined work piece. The two sides of the machined work piece are two laser beams which are respectively acted on the two side faces of the machined work piece. The laser beams at the two sides of the machined work piece are onthe same straight line or intersectant in the work piece. The two laser beams can be respectively generated by two lasers or generated by one laser with a beam splitter. The method comprises the steps: inputting cut graph into a computer, and controlling the middle displacement platform to move according to a track by software, to complete the cutting machining. By laser double-faced synchronousmachining, the machining depth at one time is more than 1 times of that of the single-faced machining. Compared with traditional double-faced machining, the invention does not need adjust a clamping tool in an overturning way, can complete the machining by clamping at one time, has balanced heat action applied to the two faces of the work piece, has low remnant stress and heat deformation after cutting, improves the cutting quality, and realizes the double-faced synchronous cutting to various superhard materials such as PDC, PCB and composite sheet thereof, ceramics, etc.

Description

Technical field [0001] The invention relates to a laser double-sided synchronous processing system and a processing method. It belongs to the technical field of superhard material processing industry. Background technique [0002] Most of the current laser processing equipment is like figure 1 As shown, the laser head is vertically downward, and the processing methods are single-sided processing or double-sided asynchronous processing. The total thickness that can be processed by single-sided processing is about half that of double-sided processing. Compared with double-sided synchronous processing, double-sided asynchronous processing has the following defects: [0003] Need to clamp the workpiece twice, increase the clamping time and reduce the overall processing efficiency; [0004] Two clampings can easily cause clamping errors, leading to misalignment of double-sided cutting; [0005] The repetitive positioning accuracy of the worktable is not enough, and the double-sided cutt...
