Description

Technical Field

[0001] The invention relates to the field of lasers, and in particular to a laser cross spot position adjustment mechanism. Background Art

[0002] Laser cross spot is a special laser spot shape, mainly composed of two vertically crossed laser lines, forming a clear cross intersection. The formation of laser cross spot mainly depends on the laser generator and optical system. The laser generator generates laser by exciting the semiconductor material through electric current, producing a high-intensity, monochromatic laser beam. Subsequently, this laser beam is focused and adjusted by the optical system, and finally forms the desired cross spot pattern through the diffraction of light and the change of refraction direction.

[0003] When the laser cross spot is assembled, due to the installation accuracy, the two lasers usually cannot form a standard cross spot pattern. Therefore, in the quality inspection stage, the spots of the two lasers need to be adaptively adjusted.

[0004] The existing adjustment method has a single function and can only adjust in one direction before adjusting in the other direction, for example, adjusting up and down first and then left and right or adjusting left and right first and then up and down. This adjustment method greatly increases the adjustment time and reduces work efficiency. Although the adjustment method has been improved in the prior art so that left and right adjustment and up and down adjustment can be performed at the same time, in some adjustment requirements, only left and right adjustment is required to complete the correction of the cross spot without up and down adjustment. This makes the method that can be adjusted synchronously in both directions unusable. Therefore, it is urgent to develop a method that can adjust left and right separately and adjust up and down synchronously. Summary of the invention

[0005] In order to overcome the above defects of the prior art, the present invention provides a laser cross spot position adjustment mechanism to solve the problems existing in the above background technology.

[0019] Preferably, a channel for installing the arc-shaped plug plate and the arc-shaped socket is opened in the middle of the bottom of the auxiliary support block.

[0020] Preferably, in the single adjustment state, the movable adjustment screw drives the lower adjustment block to move continuously along the center direction of the universal joint so that the lower adjustment block is completely separated from the upper adjustment block, the auxiliary support block supports the upper adjustment, and the rotating adjustment screw drives the lower adjustment block to move left and right, and the moving lower adjustment block drives the laser fixing seat to move left and right.

DETAILED DESCRIPTION

[0039] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0040] The present invention provides a laser cross spot position adjustment mechanism, such as Figure 1-7 As shown, including:

[0041] The housing 1 is an annular structure, and a packaging plate 2 is arranged in the middle. Two adjustment grooves 5 are arranged on the side of the housing 1, and the two adjustment grooves 5 are arranged at an angle of 90° along the circumferential direction of the housing 1. Two light-transmitting holes 3 are arranged on the top surface of the housing 1, and lenses 4 are arranged at the light-transmitting holes 3. The bottom of the housing 1 is located directly below the two light-transmitting holes 3 and has an assembly groove 11, and a limit groove 12 is arranged on the top of the assembly groove 11;

[0042] Laser fixing seat 7, the laser fixing seat 7 is respectively assembled inside the two assembly grooves 11, and the laser fixing seat 7 is made of elastic metal material, such as alloy copper, alloy aluminum, carbon steel, etc.;

[0043] The laser 6 is fixedly mounted on the laser fixing seat 7 and is placed on the top of the assembly groove 11 through the laser fixing seat 7;

[0044] The adjusting mechanism 9 is movably installed in the adjusting slot 5. The adjusting mechanism 9 includes a pin 91 for a movable fixing mechanism fixing seat, an adjusting screw 92 movably connected to the housing 1 through a universal joint 94, an upper adjusting block 96 elastically installed at the front end of the laser fixing seat 7, a lower adjusting block 93 threadedly sleeved on the adjusting screw 92, an auxiliary supporting block 99 elastically installed at the bottom of the upper adjusting block 96, an arc-shaped plug plate 932 movably inserted at the bottom of the lower adjusting block 93 and the bottom of the laser fixing seat 7, an arc-shaped socket 71, and a baffle 97 fixedly sleeved on the adjusting screw 92. The top surfaces of the upper adjusting block 96 and the auxiliary supporting block 99 form a complementary wedge structure with the bottom surface of the lower adjusting block 93.

[0045] The laser fixture 7 can be rotated along the pin 91, so that the laser fixture 7 can be adjusted left and right according to the set adjustment screw 92, the lower adjustment block 93, the arc-shaped plug plate 932 and the arc-shaped socket 71;

[0046] In the initial state, the auxiliary support block 99 is located below the upper adjustment block 96 and supports the upper adjustment block 96. The upper adjustment block 96 is tightly in contact with the auxiliary support block 99 under the elastic force of the second spring 98. Then the lower adjustment block 93 is connected to the laser fixing seat 7 through the arc plug plate 932 and the arc socket 71. At this time, the adjusting screw 92 is screwed to drive the lower adjustment block 93 to move left and right to adjust the laser fixing seat 7 in the left and right directions.

[0047] When switching the adjustment state, push the adjustment screw 92 to rotate along the center of the universal joint 94 to push the auxiliary support block 99 out of the bottom of the upper adjustment block 96, so that the lower adjustment block 93 and the upper adjustment block 96 form a non-contact or support contact state. At this time, screwing the adjustment screw 92 drives the lower adjustment block 93 to move left and right, while the lower adjustment block 93 abuts against the upper adjustment block 96 to move up and down, thereby realizing the left and right direction of the laser fixing seat 7 alone or the left and right, up and down direction synchronous adjustment.

[0048] The assembly plate 8 is also included. The assembly plate 8 is used for packaging the assembly groove 11 to firmly fix the laser 6 and the laser fixing seat 7 in the assembly groove 11.

[0049] The laser 6 is movably mounted in the assembly slot 11 provided in the housing 1 through the laser fixing seat 7. When adjusting the laser 6 to move left and right individually, the adjusting screw 92 is pushed to move, and the adjusting screw 92 drives the lower adjusting block 93 to continuously move along the center direction of the universal joint 94 until the lower adjusting block 93 is completely separated from the upper adjusting block 96. At this time, the elastically mounted auxiliary support block 99 moves forward to support the upper adjusting block 96. The adjusting screw 92 is rotated to drive the lower adjusting block 93 to move left and right, thereby driving the laser fixing seat 7 and the laser 6 on the laser fixing seat 7 to adjust the left and right positions, so that the laser light exit window provided in the housing 1 is aligned with the light transmission hole 3.

[0050] When synchronously adjusting the laser 6 to move left and right and up and down, push the adjusting screw 92 to move. The adjusting screw 92 drives the lower adjusting block 93 to move continuously along the center direction of the universal joint 94 until the auxiliary support block 99 is pushed away from the bottom of the lower adjusting block 93, and the lower adjusting block 93 is formed to abut and support the upper adjusting block 96, and at the same time, the baffle 97 is abutted against the front end side of the lower adjusting block 93. At this time, screwing the adjusting screw 92 drives the lower adjusting block 93 to move left and right, and at the same time, the baffle 97 pushes the lower adjusting block 93 upward or moves downward under the elastic force of the second spring 98, thereby completing the left and right and up and down adjustments of the laser fixing seat 7 and the laser 6.

[0051] The initial position of the lower adjustment block 93 can provide complementary support to the upper adjustment block 96 , or the lower adjustment block 93 and the upper adjustment block 96 can be completely separated, and when separated, the auxiliary support block 99 provides complementary support to the upper adjustment block 96 .

[0052] Specifically, Figure 6 , Figure 7 , Figure 8As shown, the upper adjustment block 96 is clamped on the front end of the laser fixing seat 7, and the bottom of the upper adjustment is provided with a second inclined surface 961, and the front end of the laser fixing seat 7 is provided with a second spring 98, and the second spring 98 is placed in the limiting groove 12 to exert a downward pressure on the end of the laser fixing seat 7 and the upper adjustment block 96. In the initial state, under the downward elastic force of the second spring 98, the laser 6 and the laser fixing seat 7 are located in the middle of the assembly groove 11, and at this time, the upper adjustment block 96 is completely consistent with the auxiliary support block 99 or the lower adjustment block 93.

[0053] Specifically, Figure 6 , Figure 7 , Figure 8 As shown, the lower adjusting block 93 is in an L-shaped structure, the bottom of one end of the lower adjusting block 93 is threadedly sleeved with the adjusting screw 92, and the top surface of the other end is provided with a first inclined surface 931 complementary to the second inclined surface 961, and one end of the adjusting screw 92 is sleeved with a first spring 95, and the two ends of the first spring 95 are respectively abutted against the interior of the housing 1 and one side of the lower adjusting block 93, and the top of the lower adjusting block 93 is in contact and sliding connection with the top surface of the assembly groove 11. When the adjusting screw 92 is screwed, the lower adjusting block 93 moves left and right, and the arc plug plate 932 and the arc socket 71 connected through the sliding connection drive one end of the laser fixing seat 7 to move left and right synchronously.

[0054] Specifically, Fig. 9 As shown, the arc plug plate 932 and the arc socket 71 are both coaxially designed with the center point of the universal joint 94, and one end of the arc plug plate 932 is slidably inserted into the interior of the arc socket 71. When the adjusting screw 92 is pushed to move, the arc plug plate 932 slides inside the arc socket 71, so that the length between the arc plug plate 932 and the arc socket 71 is adaptively adjusted.

[0055] Specifically, Figure 8 , Fig. 9 , Fig.10 As shown, the top surface of the auxiliary support block 99 is provided with a third inclined surface 991 which is complementary to the second inclined surface 961, and a third spring 992 is provided at the rear of the auxiliary support block 99 and the front end of the laser fixing seat 7. Both sides of the bottom of the auxiliary support block 99 are slidably connected with a guide rod 993, and the guide rod 993 can be detachably assembled on the assembly plate 8. When the lower adjustment block 93 is not in complementary contact support with the inclined surface of the upper adjustment block 96, under the elastic force of the third spring 992 and the guiding action of the guide rod 993, the auxiliary support block 99 moves forward to form complementary contact support with the inclined surface of the upper adjustment block 96. At this time, the lower adjustment block 93 can be completely separated from the upper adjustment block 96 to perform independent movement to adjust the left and right positions of the laser 6 and the laser fixing seat 7.

[0056] Specifically, Figure 7 , Figure 8As shown, a groove 962 is provided at the front end of the upper adjusting block 96 near the side of the lower adjusting block 93. When the lower adjusting block 93 is moved to the bottom of the upper adjusting block 96 and supports the upper adjusting block 96, the blocking piece 97 moves synchronously with the lower adjusting block 93 and abuts against the groove 962. When the moving lower adjusting block 93 and the inclined surface of the upper adjusting block 96 are completely complementary to each other in contact and support, the blocking piece 97 abuts against the groove 962 provided in the upper adjusting block 96. At this time, if the adjusting screw 92 is screwed to drive the lower adjusting block 93 to move left and right, the blocking piece 97 abuts against the upper adjusting block 96 and pushes the upper adjusting block 96 to move up and down on the inclined surface of the lower adjusting block 93.

[0057] Further, such as Figure 8 As shown, a channel for installing the arc-shaped plug plate 932 and the arc-shaped socket 71 is opened in the middle of the bottom of the auxiliary support block 99.

[0058] Further, such as Figure 5 , Figure 6 As shown, a blind hole 13 is opened on one side of the adjustment slot of the housing 1, and a fourth spring 10 is connected to the interior of the blind hole 13. One end of the fourth spring 10 is fixedly connected to the interior of the blind hole 13, and the other end is hooked on the adjustment screw 92. Under the pulling force of the fourth spring 10, the initial position of the adjustment screw 92 is moved away from the laser fixing seat 7.

[0059] Working principle of the present invention:

[0060] When adjusting the laser 6 to move left and right individually, push the adjusting screw 92 to move, and the adjusting screw 92 drives the lower adjusting block 93 to move continuously along the center direction of the universal joint 94. At this time, one end of the arc plug plate 932 slides inside the arc socket 71, so that the arc plug plate 932 is recovered until the lower adjusting block 93 is completely separated from the upper adjusting block 96. At this time, the elastically installed auxiliary support block 99 moves forward to support the upper adjusting block 96. The adjusting screw 92 is rotated to drive the lower adjusting block 93 to move left and right. Under the connection between the arc plug plate 932 and the arc socket 71, the laser fixing seat 7 and the laser 6 on the laser fixing seat 7 are driven to adjust the left and right positions, so that the laser light outlet window set in the housing 1 is aligned with the light transmission hole 3;

[0061] When synchronously adjusting the laser 6 to move left and right and up and down, push the adjusting screw 92 to move, and the adjusting screw 92 drives the lower adjusting block 93 to move continuously along the center direction of the universal joint 94. At this time, one end of the arc plug plate 932 slides inside the arc socket 71, so that the arc plug plate 932 is recovered until the auxiliary support block 99 is pushed away from the bottom of the lower adjusting block 93, and the lower adjusting block 93 is formed to abut and support the upper adjusting block 96, and at the same time, the baffle 97 is abutted against the front end side of the lower adjusting block 93. At this time, screwing the adjusting screw 92 drives the lower adjusting block 93 to move left and right, and at the same time, the baffle 97 pushes the lower adjusting block 93 upward or moves downward under the elastic force of the second spring 98, thereby completing the left and right and up and down adjustments of the laser fixing seat 7 and the laser 6.
