Description

Technical Field

[0001] The present invention relates to the technical field of laser detection, and particularly relates to a flattening detection device for the housing of a linear vibration motor. Background Art

[0002] A linear vibration motor is a vibration device that directly converts electrical energy into linear reciprocating motion (instead of rotational motion). Different from traditional rotary motors (which generate vibration through the rotation of eccentric mass blocks), it achieves direct linear motion through electromagnetic drive, thereby generating a more precise and controllable vibration effect.

[0003] All components inside the linear vibration motor need to be installed in the housing. In order to ensure that the housing of the linear vibration motor meets the factory standards, quality inspection is required for the deformation (flattening) of the metal housing caused by external forces during manufacturing or use. The core objective is to ensure that the flatness, structural integrity, and functional reliability of the metal housing meet the design requirements. However, due to the small volume of the housing of the linear vibration motor, only laser scanning can be used for flattening detection.

[0004] However, in the existing detection process of the housing of the linear vibration motor, due to the small volume of the housing, although there is no impact on the laser scanning of the outer contour of the housing, the inside of the housing mainly contacts the components of the motor. During the process of scanning the outer contour, due to the small volume inside, it is not convenient to accurately scan and detect the inner contour when the laser scanning passes by, which is likely to affect the detection accuracy and increase the detection error rate.

[0005] Therefore, it is necessary to provide a flattening detection device for the housing of a linear vibration motor to solve the above technical problems. Summary of the Invention

[0057] 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.

[0058] The present invention provides a flattening detection device for the housing of a linear vibration motor.

[0059] First Embodiment:

[0060] Please refer to Figures 1 to 14 , a flattening detection device for the housing of a linear vibration motor, comprising a detection table 1, a translation mechanism 4, a supplementary lighting mechanism 6, and an outer contour laser detection mechanism 5;

[0061] An installation plate 2 is installed on the top of the detection table 1, and a flipping panel 3 is installed above the installation plate 2;

[0062] The translation mechanism 4 includes a pedestal 41 installed on the upper surface of the installation plate 2. A horizontally placed translation linear motor 42 is installed inside the pedestal 41, and a moving table 43 is installed on the moving end of the translation linear motor 42 through bolts;

[0063] Please refer to Figure 2 and Figure 3 : Four workpieces to be tested 11 are placed equidistantly on the detection seat 10. When the user conducts the detection, it is necessary to start the translation linear motor 42 to drive the moving table 43 to move along the horizontal direction of the pedestal 41, so as to drive the detection seat 10 and the limit seat 12 to move along the direction of the outer contour laser detection mechanism 5.

[0064] A detection seat 10 is installed on the top of the moving table 43. Workpieces to be tested 11 are placed equidistantly on the upper surface of the detection seat 10. A limit seat 12 is fixedly arranged on the side wall of the detection seat 10. Three sliding rods 13 arranged equidistantly are fixedly arranged on the inner wall of the limit seat 12. A return spring 14 is sleeved on the outer wall of each of the three sliding rods 13. A trigger rack 15 is slidably connected inside the limit seat 12, and inclined surfaces 16 with the same slope are formed on both sides of the trigger rack 15;

[0065] The outer contour laser detection mechanism 5 includes a mounting frame 51 installed on the upper surface of the pedestal 41. A lifting electric cylinder 52 is installed on the upper surface of the mounting frame 51, and a laser scanner 53 is installed at the bottom of the lifting electric cylinder 52;

[0066] Please refer to Figure 3 and Figure 4: The detection base 10 can drive all four test pieces 11 above it to move entirely below the outer contour laser detection mechanism 5. Then, the user activates the lifting electric cylinder 52 to control the laser scanner 53 to approach the test piece 11. When the test piece 11 passes by the laser scanner 53, the outer contour of the passing test piece 11 can be scanned by the laser scanner 53. After scanning, the image is displayed through the flipping panel 3, and it can be scanned out whether there are depressions, protrusions, warping, etc. on the outer contour of the test piece 11 due to external forces such as extrusion and impact, whether the thickness, length, width, etc. of the test piece 11 meet the design specifications, whether there are cracks, fractures, or material fatigue after the test piece 11 is flattened, and observe problems such as scratches, oxidation, and coating peeling.

[0067] The supplementary lighting mechanism 6 includes a base 61 installed on the upper surface of the mounting plate 2 and located on one side of the translation mechanism 4. A clamping seat 62 and a protective cover 64 are installed on the outer wall of the base 61 through bolts. The top of the clamping seat 62 is integrally provided with a top plate 63. The center of the top of the base 61 is rotatably connected to a first gear 65 inside the protective cover 64. The center of the top of the first gear 65 is integrally provided with a linkage shaft 66. A second gear 67 is rotatably connected above the top plate 63. One side of the second gear 67 is meshed with a moving rack 68. A sliding plate 69 is slidably connected above the top plate 63 and on the side far from the moving rack 68. A receiving plate 610 is installed on the upper surfaces of the moving rack 68 and the sliding plate 69 through bolts. A positioning plate 611 is installed on the top of the receiving plate 610 through bolts. A support frame 612 is fixedly provided on the upper surface of the positioning plate 611. Four sleeves 613 are installed on the outer wall of the support frame 612 through bolts;

[0068] A first limiting shaft 614 is keyway-connected to the center of the bottom of the first gear 65. A first torsion spring 615 is sleeved on the outer wall of the first limiting shaft 614. Supplementary lighting lamps 616 are installed inside the four sleeves 613 on the outer wall of the support frame 612.

[0069] Please refer to Figure 13 and Figure 14 : After the outer contour detection is completed, the detection base 10 can be further controlled to drive the test piece 11 away from the outer contour laser detection mechanism 5. And when the detection base 10 moves, the limit seat 12 will also move along with the movement of the detection base 10;

[0070] Please refer to Figure 13 and Figure 5: When the inclined surface 16 on the trigger rack 15 enters the position of the first gear 65, the force in the translation direction will control the inclined surface 16 to force the first gear 65, so that the trigger rack 15 slides and contracts on the slide rod 13, and the return spring 14 is compressed while contracting. When the trigger rack 15 is completely engaged with the first gear 65, the movement of the trigger rack 15 can engage and drive the first gear 65 to rotate clockwise;

[0071] See also Figure 11 , Figure 13 and Figure 15 : When the first gear 65 rotates clockwise, it can drive the second gear 67 to rotate clockwise. When the second gear 67 rotates clockwise, the meshing transmission controls the moving rack 68 to control the receiving plate 610, the positioning plate 611 and the support frame 612 to control the four sleeves 613 to move toward the upper surface of the test piece 11. Finally, the four sleeves 613 will move to the upper surfaces of the four test pieces 11.

[0072] When the four sleeves 613 cover the four test pieces 11 , the user can activate the fill light 616 to illuminate the inside of the four test pieces 11 .

[0073] The three slide bars 13 are slidably connected to the trigger rack 15 , and the top end of the linkage shaft 66 is connected to the axis of the second gear 67 via a keyway.

[0074] The bottom of the movable rack 68 and the slide plate 69 are slidably connected to the top plate 63 through a "T"-shaped block, the trigger rack 15 and the first gear 65 are adapted to each other, and the upper and lower ends of the first torsion spring 615 are embedded in the top of the base 61 and the bottom of the first limiting shaft 614.

[0075] Understandable: From Figure 6 , Figure 7 and Figure 10 It can be seen that the linkage shaft 66 on the first gear 65 is connected to the second gear 67, so when the first gear 65 rotates, it can drive the linkage shaft 66 to rotate and control the rotation of the second gear 67;

[0076] Secondly, the receiving plate 610 spans the entire second gear 67 to connect the slide plate 69 and the moving rack 68, so that when the moving rack 68 moves, it can drive the slide plate 69 to slide and connect, so that the entire positioning plate 611 and the support frame 612 can move freely back and forth, and secondly, the stability of the positioning plate 611 and the support frame 612 during movement can be ensured;

[0077] The first gear 65 rotates inside the shield 64 , and an escape groove is provided on the outer side of the shield 64 , which can ensure that the trigger rack 15 can stably contact and mesh with the first gear 65 .

[0078] Secondly, in combination with Figure 8 and Figure 9 it can be known that: the first gear 65 and the base 61 are connected by the first torsion spring 615. When the first gear 65 rotates, it will drive the first limit shaft 614 at the bottom to control the first torsion spring 615 to rotate and twist. When the first gear 65 loses the meshing tension of the trigger rack 15, the first torsion spring 615 resets to the initial state. When the first torsion spring 615 resets, it will drive the first gear 65 and the second gear 67 to reset to the initial state.

[0079] In this embodiment: compared with the traditional laser detection mechanism, in this case, four test pieces 11 arranged at equal intervals can be continuously placed on a detection base 10 at one time (the test pieces 11 can be selected as the corresponding linear vibration motor housing parts), and the four test pieces 11 can be freely controlled to move horizontally. During the movement, the outer contour of the test piece 11 is scanned linearly by laser, and various data of the four outer contours can be quickly scanned. Secondly, during the laser scanning of the outer contour, the trigger rack 15 can be moved to control the rotation of the first gear 65. The first gear 65 is linked to control the linkage shaft 66 to drive the second gear 67 to rotate, so that the sleeve 613 can accurately enter above the four test pieces 11, and the sleeve 613 can cover the test piece 11. Then, the user needs to start the fill light 616 to illuminate the internal environment of the test piece 11. Such a design enables the device to have the function of filling light. For the small-sized test piece 11, the internal contour can be illuminated to avoid the inside of the test piece 11 being too dark, so as to ensure the detection accuracy during subsequent internal detection, achieve a dead-angle-free detection of the internal contour, avoid excessive detection error tolerance, and at the same time, the surrounding enclosure design can ensure the maximization of the illumination brightness.

[0080] Second Embodiment:

[0081] Please refer to Figure 3 and Figures 18 to 21 , and it further includes an internal contour laser detection mechanism 7. The internal contour laser detection mechanism 7 includes a support plate 71 installed on the upper surface of the pedestal 41. A lifting electric cylinder 72 is installed on the upper surface of the support plate 71. The bottom end of the lifting electric cylinder 72 is installed with a lifting plate 73 through bolts. Four mounting cylinders 74 are fixedly provided at the bottom of the lifting plate 73. A second receiving rod 75 is rotatably connected inside the mounting cylinder 74. A key rod 77 is fixedly provided at the bottom end of the second receiving rod 75. A second torsion spring 76 is sleeved on the outer wall of the second receiving rod 75. A rotating plate 78 is installed at the bottom end of the key rod 77. A laser generator 79 is installed at the bottom of the rotating plate 78. Guide wheels 710 are rotatably connected to both ends of the rotating plate 78;

[0082] Among them, an arc-shaped inclined groove 617 is opened inside the sleeve 613.

[0083] Please refer to Figure 3 and Figure 18 : In the first embodiment, after the supplementary lighting work is completed, the four components to be measured 11 will also enter the lower part of the lifting plate 73 simultaneously.

[0084] Please refer to Figure 20 : In the initial state, the lifting plate 73 and the laser generator 79 are located directly above the sleeve 613. At this time, the supplementary light lamp 616 will be activated to illuminate the entire internal environment of the sleeve 613. Then, the user needs to activate the lifting electric cylinder 72 to drive the lifting plate 73 to control the four mounting cylinders 74 to descend.

[0085] Please refer to Figure 21 : When the mounting cylinder 74 descends, it will drive the bottom rotating plate 78 and the guide wheels 710 on both sides to descend together. When descending, the guide wheels 710 enter the interiors of the two arc-shaped inclined slots 617. Due to the influence and restriction of the inner walls of the arc-shaped inclined slots 617, the two guide wheels 710 will rotate along the trajectories of the two arc-shaped inclined slots 617. During the rotation process, the rotating plate 78 will be driven to rotate circumferentially along the axis of the mounting cylinder 74. At the same time of rotation, the laser generator 79 at the bottom of the rotating plate 78 can be rotated. In this way, when the laser generator 79 is inserted into the interior of the component to be measured 11, rotational laser scanning can be achieved.

[0086] Both the upper and lower ends of the second torsion spring 76 are embedded in the top of the second receiving rod 75 and the inner bottom of the mounting cylinder 74, and the guide wheels 710 and the arc-shaped inclined slots 617 are mutually adapted.

[0087] It can be understood that, in combination with Figure 19 it can be known that since the rotation of the rotating plate 78 is restricted by the second torsion spring 76, when the rotating plate 78 rotates, it will synchronously drive the key rod 77 to control the second receiving rod 75 to rotate. The rotation of the second receiving rod 75 will drive the second torsion spring 76 to rotate torsionally. Therefore, when the guide wheels 710 and the arc-shaped inclined slots 617 are separated, the second torsion spring 76 will reset. During the reset process, torsional rotation occurs, causing the rotated rotating plate 78 to reset to the initial state to achieve automatic reset.

[0088] In this embodiment: Compared with the traditional design, in this case, not only can the outer contour of the component to be measured 11 be detected by laser scanning, but also while supplementary lighting is carried out, the laser generator 79 can be controlled to be inserted into the interior of the component to be measured 11 to detect the internal contour of the component to be measured 11 by laser scanning. And when the laser generator 79 is being inserted, the rotating plate 78 can drive the laser generator 79 to rotate inside the component to be measured 11 to perform laser scanning on the internal contour surface, achieving all-round and non-blind-spot internal and external detection. During the internal detection, rotational detection can be carried out, further improving the detection accuracy.

[0089] Third embodiment:

[0090] Please refer to Figure 3 and Figures 15 to 17 Above the mounting plate 2 and on the front and rear sides of the translation mechanism 4, a feeding mechanism 8 and a loading mechanism 9 are respectively installed;

[0091] The feeding mechanism 8 includes a bracket 81 installed on the upper surface of the mounting plate 2. A moving linear motor 82 is installed at the top of the bracket 81. The moving end of the moving linear motor 82 is installed with a mounting seat 83. The outer wall of the mounting seat 83 is installed with a tray 84. The upper surface of the tray 84 is provided with equally spaced material grooves 85. A feeding drag chain 86 is rotatably connected to the side of the mounting seat 83.

[0092] Please refer to Figure 15 : Before detection, the batch of workpieces to be measured 11 can be sequentially embedded inside the material grooves 85. The user can start the moving linear motor 82 to automatically control the mounting seat 83 to drive the tray 84 to move horizontally, and can control the extension and entry of the tray 84 according to the number of workpieces to be measured 11 inside the material grooves 85.

[0093] The loading mechanism 9 includes a base 91 installed on the upper surface of the mounting plate 2. A transverse seat 92 is installed at the top of the base 91. A transverse linear motor 93 is installed inside the transverse seat 92. The moving end of the transverse linear motor 93 is installed with a longitudinal linear motor 94. The moving end of the longitudinal linear motor 94 is installed with a vertical seat 95. A vertical linear motor 98 is installed on the outer wall of the vertical seat 95. The moving end of the vertical linear motor 98 is installed with equally spaced adjustable plates 99. A loading suction cup 910 is installed on the outer wall of each adjustable plate 99. A transverse drag chain 96 is rotatably installed on the side wall of the transverse seat 92. A longitudinal drag chain 97 is rotatably installed outside the vertical seat 95.

[0094] The feeding drag chain 86 is rotatably connected to the tray 84, and the material grooves 85 and the workpieces to be measured 11 are mutually adapted.

[0095] Please refer to Figure 16 and Figure 17 : When the tray 84 is close to the position of the loading mechanism 9, the user can start the transverse linear motor 93 and the longitudinal linear motor 94. The transverse linear motor 93 can mainly control the horizontal movement of the longitudinal linear motor 94. The longitudinal linear motor 94 can mainly control the forward and backward movement of the vertical seat 95. The user can also start the vertical linear motor 98 to control the up and down movement of the adjustable plate 99. In this way, through the cooperation between the transverse linear motor 93, the longitudinal linear motor 94 and the vertical linear motor 98, the three-axis movement of the adjustable plate 99 can be realized, and the all-round movement of the loading suction cup 910 can be realized. The loading suction cup 910 can suck the workpieces to be measured 11 inside the material grooves 85 and place them on the detection seat 10 to complete the feeding and loading work before detection.

[0096] In this embodiment, equidistantly distributed material troughs 85 are provided inside the tray 84 for placing batches of test pieces 11, and the cooperation between the transverse linear motor 93, the longitudinal linear motor 94 and the vertical linear motor 98 realizes the three-axis linkage movement of the adjustable plate 99, so that the test pieces 11 in the material trough 85 can be sucked and placed on the detection seat 10 in all directions without dead angles. Such a design can quickly realize automatic batch discharge and loading work, and suction loading can be performed for small test pieces 11, which can avoid damaging the outer surface of the test pieces 11 and can well protect the test pieces 11 during the loading process.

[0097] Please refer to Figures 1 to 21 The working principle of a linear vibration motor housing flattening detection device provided by the present invention is as follows:

[0098] Step S1: Start the lifting electric cylinder 52 to control the laser scanner 53 to approach the test piece 11. When the test piece 11 passes through the laser scanner 53, the laser scanner 53 can scan the outer contour of the test piece 11. The image after scanning is displayed through the flip panel 3. It can scan: whether the outer contour of the test piece 11 is concave, convex or warped due to external forces such as extrusion and impact, whether the thickness, length, width, etc. of the test piece 11 meet the design specifications, whether cracks, fractures or material fatigue occur after the test piece 11 is flattened, and observe scratches, oxidation, coating shedding and other problems;

[0099] Step S2: After the outer contour detection is completed, the detection seat 10 can continue to be controlled to drive the workpiece 11 to be tested away from the outer contour laser detection mechanism 5, and when the detection seat 10 moves, the limit seat 12 will also move with the movement of the detection seat 10. When the inclined surface 16 on the trigger rack 15 enters the position of the first gear 65, the force in the translation direction will control the control inclined surface 16 to bear the force of the first gear 65, so that the trigger rack 15 slides and contracts on the slide bar 13, and the reset spring 14 is compressed while contracting. When the trigger rack 15 is completely aligned with the first gear When the first gear 65 is engaged, the movement of the trigger rack 15 can be engaged to drive the first gear 65 to rotate clockwise. When the first gear 65 rotates clockwise, the second gear 67 can be driven to rotate clockwise. When the second gear 67 rotates clockwise, the meshing transmission controls the moving rack 68 to control the receiving plate 610, the positioning plate 611 and the support frame 612 to control the four sleeves 613 to move toward the upper surface of the test piece 11. Finally, the four sleeves 613 will move to the upper surfaces of the four test pieces 11, and the fill light 616 will be started to illuminate the inside of the four test pieces 11.

[0100] Step S3: Start the lifting electric cylinder 72 to drive the lifting plate 73 to control the four mounting cylinders 74 to descend. When the mounting cylinders 74 descend, they will drive the rotating plate 78 at the bottom and the guide wheels 710 on both sides to descend together. When the guide wheels 710 descend, they enter the interiors of the two arc-shaped inclined slots 617. Due to the influence and restriction of the inner walls of the arc-shaped inclined slots 617, the two guide wheels 710 will rotate along the trajectories of the two arc-shaped inclined slots 617. During the rotation process, the rotating plate 78 will be driven to rotate circumferentially along the axis of the mounting cylinder 74. At the same time of rotation, the laser generator 79 at the bottom of the rotating plate 78 can be rotated. In this way, when the laser generator 79 is inserted into the test piece 11, rotational laser scanning can be achieved.

Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
