Description

Technical Field

[0001] The present invention relates to the technical field of intelligent jigs, and in particular to a laser cutting and marking integrated jig for precision lenses. Background Art

[0002] After the injection molding and demolding of an automotive headlight lens, it is a lens assembly. As Figure 1 shown, the lens assembly includes a rod portion (also known as a gate) and lens portions with hemispherical structures connected to both ends of the rod portion. It is necessary to cut and separate the rod portion and the lens portions (the cutting portion is as shown at A in Figure 1 ), and also mark numbers on the side surface of the lens portion (the marking portion is as shown at B in Figure 1 ). The prior application patent with the publication number CN114178725 discloses a lens cutting and marking device, which can design special jigs for each type of lens and is applicable to both laser cutting and marking stations. However, this cutting and marking device is not applicable to the lens assembly as Figure 1 shown. The lens portion has a hemispherical structure, and it is impossible to ensure the clamping stability of the lens after rotating 90° by the pressing mechanism acting on the side of the lens in this device, which affects the marking quality. In addition, when loading the workpiece, a downward force will be applied to the workpiece, which will cause the bearing mechanism supporting the lens portion to deflect, and this force will act on the motor shaft of the steering motor at the same time. Each time the workpiece is loaded, the pressure on the motor shaft will cause a significant reduction in the service life of the motor; and there is a risk of collision between the lens assembly of this device and the cutting surface of the gate driven by the motor shaft of the steering motor.

[0038] Now, the present invention will be further described in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0039] Such as Figure 2As shown, a laser cutting and marking integrated jig for precision lenses includes a substrate 100, on which are disposed two sets of identical positioning and clamping mechanisms 300 for clamping lens components 200 to be processed, and the lens components 200 (such as Figure 1 As shown) includes a rod portion 201 and a hemispherical lens portion 202 connected to both ends of the rod portion 201, and the positioning and clamping mechanism 300 includes a positioning and clamping module for positioning the two lens portions 202 and a supporting and pressing module for the rod portion 201; Figure 3 As shown, the positioning and clamping module includes a positioning module, a positioning and balancing module and a rotating module. The positioning module includes a turntable 301 supporting the lens part 202 and a positioning component 302 limiting the lens part 202. The positioning component 302 is arranged on the turntable 301. The rotating module has a driving component 303 driving the turntable to rotate downward 90°. The positioning and balancing module is arranged below the positioning module. The positioning and balancing module has a balancing component 304 preventing the turntable 301 from deflecting when the lens component 200 is placed in the positioning module. The fixture is composed of two sets of identical positioning and clamping mechanisms 300. When one lens component 200 is laser cut, another lens component 200 can be laser marked at the same time.

[0040] like Figure 4 As shown, the positioning module 302 also includes two relatively arranged support frames 305, and the two ends of the turntable 301 are protruded near the outer edge to form mounting parts 3011, and the two mounting parts 3011 are movably connected to the upper parts of the two support frames 305, and the inner side of the turntable 301 has an avoidance gap 3012.

[0041] Specifically, the positioning assembly 302 includes an edge stopper and a side wall tightening member. The edge stopper is arranged at the inner and outer edges of the turntable 301, and the side wall tightening member is arranged in the middle of the two ends of the turntable 301. In this embodiment, the edge stopper is an eccentric positioning column 3021, and is arranged in four numbers. The four eccentric positioning columns 3021 are respectively arranged near the four corners of the turntable 301. The four eccentric positioning columns 3021 are connected to the turntable 301 by threads, and the radial position of the lens part 202 can be fine-tuned to adapt to lens assemblies 200 of different sizes. Each lens part 202 will also be positioned by four eccentric positioning columns 3021 to ensure that the lens part 202 is difficult to move on the horizontal plane.

[0042] In this embodiment, if Figure 5 As shown, the side wall pressing member is a spring plunger 3022, which is transversely arranged in a connecting member 306, and the connecting member 306 is L-shaped and fixed at the middle of the end of the turntable 301. A supporting pad 307 is arranged on the turntable 301 near the connecting member 306. When the lens assembly 200 is placed, the left and right side walls of each lens portion 202 are pressed by two spring plungers 3022 and supported by the supporting pad 307, so that the upper, lower, left and right sides are limited.

[0043] As shown Figure 6 in the figure, the balancing component 304 includes a resisting post 3041, a lifting rod 3042 and a thimble 3043. The resisting post 3041 is vertically arranged on the horizontal section of the connecting member 306. The lifting rod 3042 is horizontally installed under the turntable 301 through a first air cylinder 3044. The thimbles 3043 are arranged at both ends of the lifting rod 3042, and the central axis of the thimble 3043 is on the same straight line as the central axis of the resisting post 3041. When placing the lens component 200, it is necessary to press the lens component 200 downward forcefully in the vertical direction so that the contact surfaces on both left and right sides of the lens component 200 are located below the spring plunger 3022, which is convenient for the spring plunger 3022 to accurately fix the position of the lens component 200. However, the bending moment generated during pressing may cause the turntable 301 to rotate slightly. Therefore, when placing the lens component 200, the lifting rod 3042 is lifted upward by the first air cylinder 3044 until the thimble 3043 touches the lower end of the resisting post 3041. The upward lifting force applied by the thimble 3043 to the resisting post 3041 can balance the downward force when placing the lens component 200, and can prevent the turntable 301 from rotating when placing the lens component 200.

[0044] As shown Figure 7 in the figure, the driving component 303 includes a motor 3031, a worm gear 3032 and a worm 3033. The motor 3031 is vertically installed on the outer side wall of any support frame 305, and a worm 3033 is connected to the output shaft of the motor 3031. A worm gear 3032 is horizontally installed on the upper part of the support frame 305. The worm gear 3032 is installed on a worm gear shaft 3034. The worm gear shaft 3034 is movably connected to an installation part 3011. The other installation part 3011 is movably connected to the support frame 305 through a rotating shaft 3035. The central axes of the rotating shaft 3035 and the worm gear shaft 3034 are located above the upper surface of the rod part 201. The worm gear 3032 and the worm 3033 are arranged inside the motor housing 3036. The motor 3031 drives the turntable 301 to rotate through the worm gear 3032 and the worm 3033. The axis of the motor 3031 is arranged in a vertical position, so as to avoid the direct action of pressure. The central axes of the rotating shaft 3035 and the worm gear shaft 3034 are located above the upper surface of the rod part 201, that is, the rotation center line of the turntable 301 is higher than the cutting part in the vertical position, so as to avoid the lens part 202 colliding with the cutting surface of the rod part 301 during rotation. The motor housing 3036 can prevent the ablation products generated during laser cutting and marking from contacting the worm gear 3032 and the worm 3033, affecting the transmission accuracy.

[0045] As shown Figure 8As shown in the figure, the support and pressing module includes a support assembly 308 and a pressing assembly 309. The support assembly 308 includes a support 3081, a microswitch 3082, and a travel switch 3083. The support 3081 is fixed on the substrate 100. An installation groove 30811 is provided at one side edge of the top of the support 3081. The microswitch 3082 is fixed in the installation groove 30811, and the contact piece of the microswitch 3082 extends out of the upper surface of the support 3081. The travel switch 3083 is installed on the outer edge of the top of the support 3081 through a bracket 3084. When the lens assembly 200 is loaded, the rod portion 201 contacts the contact piece of the microswitch 3082, presses down the contact piece, and triggers a signal indicating that the lens assembly 200 is in place to be sent to the host computer. The pressing assembly 309 includes a second cylinder 3091, a connecting rod 3092, and a pressing head 3093. The second cylinder 3091 is installed on the inner side wall of the support 3081. The end of the telescopic rod of the second cylinder 3091 is connected to one end of the connecting rod 3092, and the other end of the connecting rod 3092 is connected to the vertically downward pressing head 3093. The second cylinder 3091 drives the pressing head 3093 to drop and clamp the rod portion 201 in the middle of the lens assembly 200. Through the microswitch 3082, it can accurately identify whether there is a protrusion in the middle position of the lens assembly 200 to accurately identify the type of the lens assembly 200.

[0046] As Figure 9 shown in the figure, a purging mechanism 500 is further provided on the substrate 100. The purging mechanism 500 includes a mounting bracket 501 and four ion air guns 502. The mounting bracket 501 includes a mounting base 5011, a column 5012, a cross bar 5013, and a longitudinal bar 5014. The mounting base 5011 is fixed on the substrate 100. The lower end of the column 5012 is connected to the mounting base 5011. The upper end of the column 5012 is connected to a cross bar 5013 through a connecting block 5015. Both ends of the cross bar 5013 are respectively connected to a longitudinal bar 5014 through a connecting block 5015. Two ion air guns 502 are installed on each longitudinal bar 5014, and each ion air gun 502 is aligned with the separation position of the rod portion 201 and the lens portion 202. Preferably, a wind hood 5021 with a blowing port is provided at the outlet of the ion air gun 502. During laser processing, the ion air gun 502 can blow out ionized air to remove the static electricity on the lens assembly 200 during laser processing. The blowing port can blow away the residues after laser ablation and cool the laser processing site at the same time.

[0047] The substrate 100 is provided with positioning pin holes and positioning bolt holes. A positioning pin and a positioning bolt are respectively arranged in the positioning pin holes and the positioning bolt holes. The positioning pin can achieve the quick positioning of the jig of the present invention on the workbench of the laser processing equipment, and the positioning screw fixes the jig on the workbench through threaded connection. And a graphite strip 400 is arranged at the position between the support and pressing module and the positioning and clamping module on the substrate 100, that is, the graphite strip 400 is placed at the lower end of the cutting part of the lens assembly 200, which can prevent the laser from penetrating to the substrate 100 after the lens assembly 200 is cut, damaging the workbench.

[0048] In addition, another implementation manner of the side wall pressing member is to use a pneumatic jaw. Compared with the pneumatic jaw of the prior art, the end of its jaw adopts a ball head structure similar to the end of the spring plunger 3022.

[0049] Specific working principle:

[0050] 1. Manual feeding, place the lens part 202 of the lens assembly 200 on the turntable 301 of the positioning and clamping module, press down the two contact surfaces of the lens part 202 downward with force until they are below the spring plunger 3022. The lifting rod 3042 is lifted upward by the driving of the first cylinder 3044 until the ejector pin 3043 contacts the lower end of the abutting column 3041. The upward lifting force applied by the ejector pin 3043 to the abutting column 3041 balances the downward force of placing the lens part 202. At the same time, the rod part 201 is placed on the support assembly 308, and the rod part 201 contacts the contact piece of the microswitch 3082, presses down the contact piece, and triggers the signal of the lens assembly 200 in place to the upper computer. Through the microswitch 3082, it can accurately identify whether there is a protrusion in the middle position of the lens assembly 200 to accurately identify the type of the lens assembly 200;

[0051] 2. The laser cutting unit cuts the separation part of the rod part 201 and the lens part 202. During cutting, the ion air gun 502 blows out ion wind to remove the static electricity on the lens assembly 200 during laser processing. The air blowing port blows away the residue after laser ablation, and at the same time cools the laser processing part;

[0052] 3. The motor 3031 is started to drive the worm 3033 to rotate, so that the worm gear 3032 rotates. The worm gear 3032 drives the worm gear shaft 3034 to rotate. Through the rotating shaft 3035 and the worm gear shaft 3034, the turntable 301 rotates downward by 90° to perform laser marking and numbering on the marking part of the lens part 202.
