Description

Technical Field

[0001] The invention relates to the technical field of angle detection of a reflective lens of a galvanometer motor, and in particular to an angle detection device for a reflective lens of a galvanometer motor. Background Art

[0002] The reflective lens of the galvanometer motor refers to the optical element installed on the galvanometer motor, which is used to reflect the light beam or adjust the direction of the light path. The galvanometer motor usually includes a rotatable reflective lens, and the angle of this reflective lens can be controlled and adjusted by the motor drive system. Whether the actual rotation angle of the reflective lens is the same as the angle recorded by the motor drive system will directly reflect whether the galvanometer motor and the galvanometer motor unit composed of the motor drive system are qualified. Therefore, when the galvanometer motor unit leaves the factory, it is also necessary to detect whether the rotation angle of the reflective lens is accurate. However, the common detection device is more complicated to install or disassemble the galvanometer motor unit, which is not conducive to the detection device to quickly detect a large number of galvanometer motor units. For this reason, we have introduced an angle detection device for the reflective lens of the galvanometer motor. Summary of the invention

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 2. When the positioning drive mechanism is pressed down, the air in the cylinder on the inverted U-shaped frame is compressed and enters the cylinder mechanism, so that the cylinder mechanism drives the mounting seat to move to the left until the beam tube is inserted into the sight hole in the middle of the sight disc. The laser emits a laser beam, which is emitted through the center of the beam tube. The beam tube blocks the interference of the laser beam from the outside. The setting of the beam tube is to reduce the loss of the laser beam and realize that the laser beam is accurately shot from the sight hole to the reflective lens after the beam tube is inserted into the sight hole in the middle of the sight disc.

[0032] 3. After the measurement is completed, the galvanometer motor reflector lens assembly needs to be disassembled, and then a new galvanometer motor reflector lens assembly is replaced according to the above method to continue the measurement. When dismantling the galvanometer motor reflector lens assembly after the measurement, it is only necessary to manually rotate the rotating ring seat so that the clamping seat on the rotating ring seat pushes the rotating arm, so that the rotating arm rotates with the vertical axis as the center of the circle until the clamping block at the top end of the vertical axis is disengaged from the clamping seat, and the clamping block is no longer above the rotating ring seat; at this time, the rotating arm no longer presses the rotating ring seat, and at this time, under the elastic force of the second vertical spring on the horizontal plate, the positioning drive mechanism moves upward as a whole until the positioning drive mechanism pushes the galvanometer motor reflector lens assembly upward as a whole, and after the limit seat pushes out the limit support mechanism, the galvanometer motor reflector lens assembly can be manually removed, so that the galvanometer motor reflector lens assembly can be quickly disassembled.

[0033] 4. The installation and disassembly of the galvanometer motor reflective lens assembly is simple and quick, which is conducive to improving the measurement of the angle of the reflective lens of the galvanometer motor reflective lens assembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] Example:

[0053] See also Figure 1-16 , the present invention provides a technical solution:

[0054] An angle detection device for a reflective lens of a galvanometer motor comprises a base 9, an inverted U-shaped frame 8 is provided on the left side of the upper end of the base 9, a front-to-back symmetrical guide mechanism 4 is provided on the inverted U-shaped frame 8, and a limit support mechanism 5 for mounting a reflective lens assembly 1 of a galvanometer motor is provided on the upper inner end of the guide mechanism 4;

[0055] like Figure 5 , 6As shown in FIG. 8 , the guide mechanism 4 includes a guide seat 401 fixed to the upper end of the inverted U-shaped frame 8 in a front-to-back symmetrical manner and a bracket 404 fixed to the upper end of the guide seat 401 , and a support column 405 fixed to the middle lower end of the bracket 404 ;

[0056] The limit support mechanism 5 includes an arc-shaped support plate 502 fixed to the inner upper end of the guide seat 401 and an arc-shaped limit plate 501 fixed to the outer upper end of the arc-shaped support plate 502. The arc-shaped support plate 502 is used to support the lower end of the limit seat 103, and the arc-shaped limit plate 501 is used to be close to the side of the limit seat 103. The limit seat 103 is circular in design, and the diameter of the inner wall of the arc-shaped limit plate 501 is consistent with the outer diameter of the limit seat 103.

[0057] The inverted U-shaped frame 8 is also provided with a positioning drive mechanism 6 located inside the position limiting support mechanism 5;

[0058] The positioning drive mechanism 6 includes a vertical rack 601 meshed with the inner sides of the left and right gear sets 703, a piston plate 604 fixed at the lower end of the vertical rack 601, a horizontal plate 602 disposed at the inner end of the vertical rack 601, and a buffer rubber tube 606 fixed at the lower end of the horizontal plate 602;

[0059] A through hole 802 for passing the rotating shaft 104 is provided in the middle of the upper end of the inverted U-shaped frame 8. The size of the through hole 802 must also be sufficient to allow the reflective lens 105 at the lower end of the rotating shaft 104 to pass through.

[0060] A vertical groove 801 is provided at the upper end of the inverted U-shaped frame 8, and a cylinder 808 is fixed in the top wall of the inverted U-shaped frame 8, and the cylinder 808 is located below the vertical groove 801;

[0061] The piston disc 604 is located in the cylinder 808. A sealing ring 605 is sleeved on the side of the piston disc 604. The sealing ring 605 is tightly attached to the inner wall of the cylinder 808. Through the setting of the sealing ring 605, when the piston disc 604 moves downward in the cylinder 808, the air in the cylinder 808 can be completely squeezed into the cylinder body 902 through the air pipe 908, so that the air entering the cylinder body 902 pushes the piston rubber disc to the left, so that the piston rod 904 is extended, and the mounting seat 905 is pushed to the left along the slide seat 901.

[0062] The bottom of the buffer rubber tube 606 is fixed to the upper end of the inverted U-shaped frame 8, and a second vertical spring 608 is arranged inside the buffer rubber tube 606. In this way, when the galvanometer motor reflector lens assembly 1 is pressed downward, the positioning drive mechanism 6 moves downward as a whole, and the clamping seat 106 is pressed against the inner side end of the clamping mechanism 2 to realize the clamping and positioning of the galvanometer motor reflector lens assembly 1. The second vertical spring 608 is in a compressed state (such as Fig.12 as shown).

[0063] A positioning ball 603 is fixed on the top of the vertical rack 601, and a positioning groove 109 is provided at the lower end of the limit seat 103 for inserting the positioning ball 603. This arrangement enables the reflector lens 105 to be in a position such as Fig.12 The front-to-back direction shown is the initial position of the reflective lens 105 at this time.

[0064] A vertical polished rod 607 is also fixed to the lower end of the horizontal plate 602, and a limiting hole 807 is provided at the upper end of the inverted U-shaped frame 8 for inserting the vertical polished rod 607. Such a setting can ensure that the positioning drive mechanism 6 moves up and down in the vertical direction when the positioning drive mechanism 6 moves up and down as a whole, and avoid the positioning drive mechanism 6 from moving up and down.

[0065] The guide mechanism 4 is also slidably connected with a moving seat mechanism 3, and the moving seat mechanism 3 is movably connected with a clamping mechanism 2;

[0066] like Figure 4 , 8 , 10, 11 and 12, the moving seat mechanism 3 includes a moving seat 301 slidably connected to the slide groove 402 inside the guide seat 401, a U-shaped groove seat 304 provided at the upper end of the outer side of the moving seat 301, and a first vertical spring 303 provided at the upper end of the moving seat 301, and the outer end of the moving seat 301 is connected to the inner wall of the outer end of the slide groove 402 through the horizontal spring 403;

[0067] The clamping mechanism 2 comprises a rotating block 206 movably connected to the U-shaped groove seat 304 through a pin shaft 302, a rotating arm 201 movably connected to the inner end of the rotating block 206, a clamping block 202 provided at the bottom of the inner end of the rotating arm 201, and a protrusion 207 provided at the upper end of the rotating block 206;

[0068] The bracket 404 spans across the rotating block 206, and the first vertical spring 303 is supported at the middle of the lower end of the rotating block 206;

[0069] The top of the inner side end of the protrusion 207 is provided with a support inclined surface 204, and the upper end of the protrusion 207 is provided with a plane 208 connected to the outer side of the support inclined surface 204;

[0070] The bottom of the outer end of the rotating arm 201 is connected to the slot 205 at the inner end of the rotating block 206 through the vertical shaft 203 .

[0071] When the galvanometer motor reflector lens assembly 1 is pressed downward as a whole, the positioning ball 603 of the positioning drive mechanism 6 is pressed downward by the limit seat 103, driving the positioning drive mechanism 6 to move downward as a whole;

[0072] Subsequently, the vertical rack 601 of the positioning drive mechanism 6 drives the winding roller 704 to rotate through the left and right sets of gears 703 to wind up the pulling wire 701;

[0073] The pull wire 701 pulls the movable seat 301 along the slide slot 402 to move inward (i.e., in the direction close to the galvanometer motor reflective lens assembly 1), and at this time, the horizontal spring 403 is in a stretched state;

[0074] When the movable seat 301 moves inward along the slide groove 402, the clamping mechanism 2 at the upper end of the movable seat 301 is also driven to move inward until the abutting column 405 slides along the abutting inclined surface 204 to the upper end of the plane 208, so that the clamping mechanism 2 as a whole rotates around the pin shaft 302 as the center under the abutment of the abutting column 405 on the protrusion 207 of the clamping mechanism 2. At this time, the rotating block 206 presses down the first vertical spring 303, so that the first vertical spring 303 is in a compressed state, until the clamping block 202 at the inner end of the clamping mechanism 2 is pressed tightly in the clamping seat 106, thereby realizing the clamping positioning of the galvanometer motor reflector lens assembly 1 (such as Fig.12 , 13 and 14);

[0075] At the same time, a slope 107 is provided at the upper middle end of the clamping seat 106 so that when the clamping mechanism 2 as a whole rotates with the pin shaft 302 as the center and the clamping block 202 at the inner end of the clamping mechanism 2 is pressed into the clamping seat 106, the lower end of the clamping block 202 fits against the slope 107, which is beneficial to the clamping block 202 pressing the clamping seat 106.

[0076] like Figure 2 , 3 As shown in Figure 12, the galvanometer motor reflector lens assembly 1 includes a limit seat 103 located in two sets of limit support mechanisms 5, a limit cylinder 108 arranged in the middle of the upper end of the limit seat 103, a galvanometer motor 101 located in the limit cylinder 108 and fixed in the middle of the upper end of the limit seat 103, a rotating shaft 104 at the output end of the galvanometer motor 101 passes through the limit seat 103 and then fixed to the reflector lens 105, a rotating ring seat 102 sleeved on the outer side of the limit cylinder 108, and a clamping seat 106 symmetrically arranged on the upper end of the rotating ring seat 102;

[0077] The upper right side of the base 9 is slidably connected with a mounting seat 905 for mounting the laser 903, and the mounting seat 905 is driven by a cylinder mechanism;

[0078] A slide seat 901 for slidingly connecting the mounting seat 905 is provided on the right side of the upper end of the base 9 , and two groups of front and rear horizontal light rods 906 are provided on the lower right end of the inverted U-shaped frame 8 , and the horizontal light rods 906 penetrate the mounting seat 905 .

[0079] The cylinder mechanism includes a cylinder body 902 fixed to the upper right end of the slide seat 901, a piston rubber disc arranged inside the cylinder body 902, and a piston rod 904 fixed to the middle of the left end of the piston rubber disc, and the left end of the piston rod 904 is fixed to the right end of the mounting seat 905;

[0080] The right side of the cylinder body 902 is connected to the corresponding bottom side of the cylinder barrel 808 through the air pipe 908.

[0081] The front end of the laser 903 is also provided with a beam tube 907, the middle part of the right end of the inverted U-shaped frame 8 is provided with a sight disc 805, the front end of the inverted U-shaped frame 8 is provided with a scale plate 803, and the scale plate 803 is provided with a scale 804;

[0082] The wire-receiving mechanism 7 includes two left and right sets of gears 703, a winding roller 704 fixed between the left and right sets of gears 703 for winding up the wire 701, and a connecting shaft 702 that passes through the winding roller 704 and the left and right sets of gears 703;

[0083] The lower end of the arc-shaped support plate 502 is provided with two sets of connecting vertical plates 503, and the connecting shaft 702 is movably connected between the two sets of connecting vertical plates 503;

[0084] When the galvanometer motor reflector lens assembly 1 is located in the two sets of limit support mechanisms 5, the limit seat 103 presses down the positioning drive mechanism 6, so that the positioning drive mechanism 6 can reel in the pull wire 701 through the take-up mechanism 7 located at the inner end of the guide mechanism 4. At this time, the pull wire 701 pulls the movable seat mechanism 3 and the clamping mechanism 2 to move inward synchronously, and the abutment column 405 on the guide mechanism 4 abuts against the clamping mechanism 2, so that the inner end of the clamping mechanism 2 rotates downward until the inner end of the clamping mechanism 2 presses the clamping seat 106, thereby realizing the clamping and positioning of the galvanometer motor reflector lens assembly 1;

[0085] When the positioning drive mechanism 6 is pressed down, the air in the cylinder 808 on the inverted U-shaped frame 8 is compressed and enters the cylinder mechanism, so that the cylinder mechanism drives the mounting seat 905 to move leftward until the beam tube 907 is inserted into the sight hole 806 in the middle of the sight disc 805.

[0086] The laser 903 emits a laser beam, which is emitted through the center of the beam tube 907. The beam tube 907 blocks the interference of the outside world on the laser beam. The setting of the beam tube 907 is to reduce the loss of the laser beam and to enable the laser beam to be accurately emitted from the sight hole 806 to the reflective lens 105 after the beam tube 907 is inserted into the sight hole 806 in the middle of the sight disk 805.

[0087] Specifically, when in use, the galvanometer motor reflector lens assembly 1 is integrally located in the front and rear two sets of limit support mechanisms 5, so that the positioning ball 603 fixed on the top of the vertical rack 601 is inserted into the positioning groove 109 at the lower end of the limit seat 103, so that the reflector lens 105 can be placed in the following position after the galvanometer motor reflector lens assembly 1 is installed. Fig.12 At the initial position in the front-to-back direction shown;

[0088] Then, the galvanometer motor reflector lens assembly 1 is pressed down, so that the positioning drive mechanism 6 moves downward as a whole, and the arc support plate 502 is supported on the lower end of the limit seat 103, and the arc limit plate 501 is closely attached to the side of the limit seat 103 (such as Fig.12 shown);

[0089] When the positioning drive mechanism 6 is pressed down, the piston disc 604 moves downward in the cylinder 808, and completely squeezes the air in the cylinder 808 into the cylinder body 902 through the air pipe 908, so that the air entering the cylinder body 902 pushes the piston rubber disc to the left, so that the piston rod 904 is extended, and the mounting seat 905 is pushed to the left along the slide seat 901, until the beam tube 907 is inserted into the front sight hole 806 in the middle of the front sight disc 805;

[0090] At the same time, the positioning ball 603 of the positioning drive mechanism 6 is pressed downward by the limit seat 103, driving the positioning drive mechanism 6 to move downward as a whole;

[0091] Subsequently, the vertical rack 601 of the positioning drive mechanism 6 drives the winding roller 704 to rotate through the left and right sets of gears 703 to wind up the pulling wire 701;

[0092] The pull wire 701 pulls the movable seat 301 along the slide slot 402 to move inward (i.e., in the direction close to the galvanometer motor reflective lens assembly 1), and at this time, the horizontal spring 403 is in a stretched state;

[0093] When the movable seat 301 moves inward along the slide groove 402, the clamping mechanism 2 at the upper end of the movable seat 301 is also driven to move inward until the abutting column 405 slides along the abutting inclined surface 204 to the upper end of the plane 208, so that the clamping mechanism 2 as a whole rotates around the pin shaft 302 as the center under the abutment of the abutting column 405 on the protrusion 207 of the clamping mechanism 2. At this time, the rotating block 206 presses down the first vertical spring 303, so that the first vertical spring 303 is in a compressed state, until the clamping block 202 at the inner end of the clamping mechanism 2 is pressed tightly in the clamping seat 106, thereby realizing the clamping positioning of the galvanometer motor reflector lens assembly 1 (such as Fig.12 , 13 and 14);

[0094] At the same time, the lower part of the rotating shaft 104 and the reflective lens 105 pass through the through hole 802, so that the reflective lens 105 extends into the inside of the inverted U-shaped frame 8;

[0095] The PLC controller controls the laser 903 to emit a laser beam, which is emitted from the center of the beam tube 907 and accurately shot from the sight hole 806 to the reflective lens 105. The PLC controller controls the galvanometer motor 101 to operate, so that the galvanometer motor 101 drives the reflective lens 105 to rotate a certain angle at the initial position through the rotating shaft 104. The angle is counted as a' under the control of the PLC controller.

[0096] like Fig.16 As shown, the laser beam is reflected by the reflective lens 105 to the scale 804 of the scale plate 803, and then the length of the scale 804 is measured to be b;

[0097] The distance between the scale plate 803 and the center of the reflective lens 105 is known as c.

[0098] The angle between the laser beam reflected by the reflective lens 105 and the initial position of the reflective lens 105 is d.

[0099] Fig.16 Where a is the actual rotation angle of the reflective lens 105 relative to its initial position;

[0100] The initial position of the reflective lens 105 is perpendicular to the scale plate 803;

[0101] Therefore, in a right triangle, if the lengths of the two right-angled sides b and c are known, d can be found;

[0102] Then according to d+2e=90°, we can find 2e;

[0103] According to 180°-2e=2(a+d), a can be calculated, and then a is compared with a'. When the two are equal, the calculated a is the angle a' of the reflective lens 105 relative to the initial position under the control of the PLC controller. Therefore, the calculated a can be used to measure the angle of the reflective lens 105 relative to the initial position. When a and a' are equal, the galvanometer motor reflective lens assembly 1 is a qualified product;

[0104] After the measurement is completed, the galvanometer motor reflector lens assembly 1 needs to be disassembled, and then a new galvanometer motor reflector lens assembly 1 is replaced according to the above method to continue the measurement;

[0105] When removing the galvanometer motor reflector lens assembly 1 after measurement, it is only necessary to manually rotate the rotating ring seat 102 so that the clamping seat 106 on the rotating ring seat 102 pushes the rotating arm 201, so that the rotating arm 201 rotates around the vertical axis 203 as the center of the circle, until the clamping block 202 at the top end of the vertical axis 203 is disengaged from the clamping seat 106, and the clamping block 202 is no longer above the rotating ring seat 102 (such as Fig.15 shown);

[0106] At this time, the rotating arm 201 no longer presses the rotating ring seat 102. At this time, under the elastic force of the second vertical spring 608 on the horizontal plate 602, the positioning drive mechanism 6 moves upward as a whole until the positioning drive mechanism 6 pushes the galvanometer motor reflector lens assembly 1 upward as a whole. After the limit seat 103 pushes out of the limit support mechanism, the galvanometer motor reflector lens assembly 1 can be manually removed;

[0107] At the same time, the positioning drive mechanism 6 moves upward as a whole, and the vertical rack 601 of the positioning drive mechanism 6 drives the winding roller 704 to rotate through the left and right sets of gears 703, so that the winding roller 704 no longer reels the pull wire 701, and under the pulling force of the horizontal spring 403 on the moving seat 301, the moving seat 301 moves outward along the slide slot 402 to reset;

[0108] At this time, the clamping mechanism 2 and the movable seat 301 are synchronously moved outward to reset, and the abutting column 405 slides downward along the plane 208 and the abutting inclined surface 204 in sequence, so that under the elastic force of the first vertical spring 303, the clamping mechanism 2 as a whole rotates around the pin shaft 302 to reset;

[0109] When the positioning drive mechanism 6 moves upward as a whole, the piston disc 604 moves upward in the cylinder barrel 808, and the air in the cylinder body 902 is sucked into the cylinder barrel 808 through the air pipe 908. At this time, negative pressure is formed in the cylinder body 902, causing the piston rubber disc to move to the right, and the piston rod 904 retracts, pulling the mounting seat 905 to the right along the slide seat 901 until the beam tube 907 is detached from the sight hole 806 in the middle of the sight disc 805.

[0110] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
