Technical Field

[0001] The present application relates to the technical field of retro reflectors, and in particular to an automatic welding processing device for retro reflectors. Background Art

[0002] Retroreflectors, also known as reflective sheets or reflective lattices, are primarily made of PMMA, PC, and AS plastics and are primarily used in vehicles such as automobiles, motorcycles, bicycles, and electric vehicles. When reflected light from road traffic or passive light sources hits the retroreflectors, they act as a reflective warning, thereby improving driving safety.

[0003] Regarding the above-mentioned related technologies, the inventors found that traditional retro reflectors are usually double-layer plastic plates that are stacked and fixed. During the production and processing process, manual assistance is usually required to fix the stacked retro reflectors, and then welding and fixing them using welding equipment. The overall production process of the retro reflector is very labor-intensive and has low processing efficiency, so it needs to be improved. Summary of the Invention

[0009] By adopting the above technical solution, the translation component drives the placement table to gradually move away from the fixed frame, so that the placement table gradually leaves the inside of the fixed frame, so that the return reflector to be processed can be placed on the placement table; then, the translation component is controlled to gradually move the placement table to the inside of the fixed frame, and the output end of the lifting cylinder is controlled to extend, and the output end of the lifting cylinder supports the placement table, and the placement table and the top frame are abutted to stably press the stacked return reflectors, so that the reflective plate and the base plate can be welded and fixed by welding parts, and the clamping ring plate and the plug-in ring plate can be welded and fixed, thereby realizing automatic assembly and fixation of the return reflector and improving the processing efficiency of the return reflector.

[0010] The reflective plate and the base plate are overlapped, which increases the overall thickness of the retro reflector, thereby increasing the overall strength of the retro reflector; the plug-in ring plate and the clamping ring plate are clamped together, which increases the overall thickness of the retro reflector; when an external light source is irradiated on the reflective plate, the light is reflected between the plug-in ring plate and the clamping ring plate to reflect the light out; in addition, the clamping ring plate and the plug-in ring plate are overlapped with each other, which increases the connection area between the reflective plate and the base plate, and further increases the overall thickness of the retro reflector, thereby increasing the overall strength of the retro reflector.

[0011] The suction cup group absorbs the reflective plate to be processed so as to fix the reflective plate to be processed to the hanging rod; the air pump sprays air to the reflective plate to be processed through the jet hose, and increases the range of the jet cleaning of the reflective plate through the driving component, thereby reducing the dust adhering to the surface of the reflective plate to be processed, reducing the dust between the clamping ring plate and the plug-in ring plate, and improving the reflection effect of the retro reflector on the external light source, thereby improving the finished product quality and processing efficiency of the retro reflector.

[0015] By adopting the above technical solution, when the retro reflector to be processed is placed on the placement table, the two output ends of the double-headed cylinder are controlled to contract, so that the relative pressing rods gradually approach each other, and the pressing rods are pressed against the retro reflector to be processed to position and fix the retro reflector to be processed on the placement table, so as to facilitate the precise welding of the retro reflector to be processed by the welding parts, thereby improving the yield and processing effect of the retro reflector welding process.

[0016] Preferably, a side wall of the placement platform is provided with a placement groove for the retro reflector to be inserted into, and an access notch is provided on the side wall of the placement platform for facilitating the storage and access of the retro reflector.

[0017] By adopting the above technical solution, the retro reflector to be processed is placed inside the placement groove to achieve rapid positioning of the retro reflector; after the retro reflector is welded, the worker can put his finger into the access notch and press the retro reflector to quickly remove the retro reflector from the placement groove, thereby improving the processing efficiency of the retro reflector.

[0024] After the reflective plate to be processed is cleaned, the motor and the driving cylinder are rotated to make the suspension rod approach the conveyor belt again, and the base plate to be processed on the placement table is adsorbed by the adsorption component, so as to realize the rapid superposition and assembly of the reflective plate to be processed and the base plate; the output end of the driving cylinder is controlled to extend, so that a gap is left between the suspension rod and the conveyor belt for the translation frame and the placement table to move in, and then the suction cup group and the adsorption component are controlled to cancel the adsorption force on the reflective plate and the base plate, so that the retro-reflector to be processed and superimposed can be placed on the placement table for subsequent welding processing of the retro-reflector;

[0025] After the processing of the retro-reflector is completed, the translation assembly is controlled to move the placement table to the bottom of the suction cup assembly, and the suction cup assembly adsorbs the processed retro-reflector, so that the processed retro-reflector is quickly separated from the placement table;

[0026] Then, the translation frame and the placement table are controlled to move to the inside of the fixed frame, so that the processed retro-reflector can be placed on the placement table on the conveyor belt by driving the cylinder to quickly transfer the processed retro-reflector;

[0027] The above process realizes the loading, cleaning, processing and unloading of the retro-reflector to be processed, and realizes a mechanized and fully automatic retro-reflector processing flow process, thereby reducing the labor loss of manually assisted processing of the retro-reflector and improving the processing efficiency and economic benefits of producing the retro-reflector.

In this embodiment, the welding part 32 is an ultrasonic welding machine for welding and fixing the snap-in ring plate 11 of the reflective plate 1 and the plug-in ring plate 21 of the base plate 2.

[0047] Reference Figure 4 and Figure 5The interior of the fixed frame 31 is equipped with a translation assembly 4, which includes a translation frame 41 and a translation cylinder 42. The translation frame 41 is slidably mounted on the fixed frame 31 along its width. The translation frame 41 is also slidably mounted on a placement platform 311 along its height. The top of the placement platform 311 is provided with a placement groove 3111 for inserting the retro-reflector. The side wall of the placement platform 311 is provided with an access notch 3112, which communicates with the interior of the placement groove 3111. This allows workers to easily place the retro-reflector into the placement groove 3111 through the access notch 3112, or quickly remove the retro-reflector from the placement groove 3111.

[0048] Reference Figure 4 and Figure 5 The translation cylinder 42 is fixedly installed on the side wall of the fixed frame 31, and the output end of the translation cylinder 42 is fixedly connected to the translation frame 41 by bolts, and the telescopic direction of the output end of the translation cylinder 42 is parallel to the width direction of the fixed frame 31.

[0049] Reference Figure 4 and Figure 5 When the output end of the translation cylinder 42 extends, the translation frame 41 can be driven to gradually move away from the welding part 32 and gradually break away from the interior of the fixed frame 31; when the output end of the translation cylinder 42 contracts, the translation frame 41 can be driven to gradually approach the welding part 32 and gradually move into the interior of the fixed frame 31.

[0050] Reference Figure 4 and Figure 5 , a plurality of groups of lifting cylinders 313 are fixedly installed at the bottom of the fixed frame 31, and a top frame 312 is fixedly installed at the top of the fixed frame 31. When the translation frame 41 moves to the inside of the fixed frame 31, the translation frame 41 and the placement table 311 are both located between the lifting cylinders 313 and the top frame 312. At this time, the output end of the lifting cylinder 313 can be controlled to extend, and the output end of the lifting cylinder 313 can be abutted against the bottom wall of the placement table 311, so as to drive the placement table 311 gradually close to the top frame 312. The side wall of the top frame 312 facing the lifting cylinder 313 is abutted against the upper surface of the placement table 311, so that the return reflector can be stably pressed into the inside of the placement groove 3111, thereby facilitating the welding and fixing of the return reflector by the welding piece 32.

[0051] Reference Figure 4 and Figure 5 Several groups of double-headed cylinders 5 are fixedly installed on the side wall of the placement table 311 facing the translation frame 41. All double-headed cylinders 5 are spaced apart along the length direction of the placement table 311, and the extension and retraction directions of the output ends of each group of double-headed cylinders 5 are parallel to the width direction of the placement table 311.

[0052] Reference Figure 4 and Figure 5Each output end of each set of double-ended cylinders 5 is fixedly mounted with an auxiliary platform 51. Each set of auxiliary platforms 51 is slidably connected to the placement platform 311. Pressing rods 511 are fixedly mounted on the auxiliary platforms 51 on either side of the placement platform 311 to press and limit the position of the retro-reflectors on the placement platform 311. Furthermore, a clearance notch 3121 is provided on the top frame 312, allowing the pressing rods 511 to press into the clearance notch 3121 when the placement platform 311 approaches the top frame 312.

[0053] Reference Figure 1 and Figure 6 Several sets of drive cylinders 60 are mounted on the upper surface of the workbench 3. The extension and retraction directions of the output ends of all drive cylinders 60 are parallel to the vertical direction. The output ends of all drive cylinders 60 are fixedly mounted to a base 6. A mounting bracket 7 is mounted on the upper surface of the base 6 and is located on the side of the base 6 near the fixed bracket 31.

[0054] Reference Figure 6 and Figure 7 The mounting frame 7 includes a rotating shaft 71, a rotating rod 72, a positioning shaft 73, and a positioning rod 74; the rotating shaft 71 is rotatably connected to the upper surface of the base 6 at one end near the fixing frame 31, and the rotating rod 72 is fixedly connected to the rotating shaft 71 so that the rotating rod 72 and the base 6 are rotatably connected. The positioning shaft 73 is rotatably mounted on the end of the rotating rod 72 away from the base 6, and the positioning rod 74 is fixedly connected to the positioning shaft 73 so as to achieve a rotatable connection between the positioning rod 74 and the rotating rod 72. The end of the positioning rod 74 away from the rotating rod 72 is fixedly mounted with a hanging rod 61, and the side wall of the hanging rod 61 away from the positioning rod 74 is fixedly mounted with a suction cup group 611. In this embodiment, the suction cup group 611 can be a vacuum suction cup for adsorbing the reflector 1.

[0055] Reference Figure 6 and Figure 7 A gear 711 is fixedly mounted on the same end of the positioning shaft 73 and the rotating shaft 71 in the longitudinal direction. The diameter of the gear 711 on the rotating shaft 71 is larger than the diameter of the gear 711 on the positioning shaft 73. An idler gear 721 is rotatably mounted on the rotating rod 72 and meshes between the two sets of gears 711. A rotating motor 64 is fixedly mounted on the base 6. The output end of the rotating motor 64 is fixedly connected to the rotating shaft 71 to drive the rotating shaft 71 to rotate.

[0056] Reference Figure 6 and Figure 7 When the output end of the rotating motor 64 drives the rotating shaft 71 to rotate, the two sets of gears 711 are engaged and transmitted through the idler gear 721, so that the rotating shaft 71 and the positioning shaft 73 rotate in the same direction, thereby the rotating rod 72 and the positioning rod 74 rotate synchronously.

[0057] Reference Figure 1 and Figure 6 A conveyor belt 65 is installed between the base 6 and the fixed frame 31. Several groups of placement seats 651 are installed at intervals on the conveyor belt 65. The placement seats 651 are adapted to the curvature of the reflective reflector to facilitate the fixed storage of the reflective plate 1, the bottom plate 2, and the reflective reflector. When the rotating motor 64 drives the rotating rod 72 and the positioning rod 74 to rotate, the suction cup group 611 of the hanging rod 61 on the positioning rod 74 is directly opposite the reflective plate 1. At this time, the output end of the control cylinder gradually contracts, causing the base 6 to gradually approach the workbench 3 and the hanging rod 61 to gradually approach the placement seats 651 on the conveyor belt 65, allowing the suction cup group 611 to adsorb and fix the reflective plate 1.

[0058] Reference Figure 6 and Figure 7 The suspension rod 61 is also equipped with an adsorption assembly 9, which includes auxiliary suction cups 91 and positioning blocks 92. The positioning blocks 92 are integrally formed at both ends of the suspension rod 61 in the longitudinal direction. The suction cup group 611 is located between the two groups of positioning blocks 92, thereby adsorbing and fixing the reflector 1 between the two groups of positioning blocks 92.

[0059] Reference Figure 3 and Figure 6 In this embodiment, the length of the bottom plate 2 is greater than that of the reflector 1, and when the bottom plate 2 and reflector 1 overlap, both ends of the bottom plate 2 in the longitudinal direction are exposed outside the reflector 1. Each positioning block 92 has a sidewall formed with a positioning notch 921. Auxiliary suction cups 91 are fixedly mounted within each set of positioning notches 921 to secure the ends of the bottom plate 2 by suction. By pressing the ends of the bottom plate 2 into the positioning notches 921, the bottom plate 2 is also grasped and attached to the suspension rod 61, thereby achieving rapid overlap of the bottom plate 2 and the reflector 1.

[0060] Reference Figure 6 and Figure 7 A drive assembly 8 is mounted on the base 6, and the drive assembly 8 includes a drive motor 81, a sleeve rod 82, a sliding rod 83, and an auxiliary rod 84. The drive motor 81 is fixedly mounted on the end of the base 6 away from the suspension rod 61, and the sleeve rod 82 is fixedly mounted on the output end of the drive motor 81. The sliding rod 83 is slidably connected to the inside of the sleeve rod 82 along the length direction of the sleeve rod 82, and the sliding rod 83 is located at the end of the sleeve rod 82 away from the drive motor 81. The auxiliary rod 84 is rotatably connected to the end of the sliding rod 83 away from the drive motor 81, and the auxiliary rod 84 is located on the side wall of the sliding rod 83 facing the base 6. A sliding track 63 is provided on the upper surface of the base 6 for the auxiliary rod 84 to be pressed against.

[0061] Reference Figure 6 and Figure 7An air pump 62 is installed on the base 6, and an air jet hose 621 is installed on the output end of the air pump 62. The end of the air jet hose 621 away from the air pump 62 is fixedly connected to the end of the sliding rod 83 close to the hanging rod 61, so that it can move along the length direction of the sliding track 63 with the sliding rod 83, thereby cleaning the dust on the reflector 1.

[0062] The implementation principle of the automatic welding processing device for a retro-reflector according to the embodiment of the present application is as follows:

[0063] The translation cylinder 42 moves the translation frame 41 and the placement table 311 into the interior of the fixed frame 31. The conveyor belt 65 moves the reflector 1 to be processed between the base 6 and the fixed frame 31. The rotating motor 64 controls the synchronous rotation of the rotating rod 72 and the positioning rod 74 to move the suspension rod 61 above the placement seat 651. The output end of the control drive cylinder 60 is retracted, causing the suction cup assembly 611 on the suspension rod 61 to gradually approach the placement seat 651, so that the suction cup assembly 611 can automatically absorb the reflector 1 to be cleaned.

[0064] The motor 64 is used to control the rotation of the rotating rod 72 and the positioning rod 74, so that the hanging rod 61 and the suction cup assembly 611 move the reflector 1 to be cleaned to the top of the base 6. The air pump 62 and the drive motor 81 are started, so that the sliding rod 83 drives the air jet hose 621 to move along the length direction of the reflector 1, thereby blowing and cleaning the dust on the surface of the reflector 1.

[0065] After the reflective plate 1 to be processed is cleaned, the motor 64 is rotated and the cylinder 60 is driven to make the suspension rod 61 close to the conveyor belt 65 again, and the base plate 2 to be processed on the conveyor belt 65 is adsorbed by the adsorption component 9 to achieve the rapid superposition and assembly of the cleaned reflective plate 1 to be processed and the base plate 2 to be processed.

[0066] The output end of the drive cylinder 60 is controlled to extend, causing the base 6 to drive the suspension rod 61 gradually away from the workbench 3, creating a gap between the suspension rod 61 and the conveyor belt 65 for the translation frame 41 and the placement table 311 to move in. The suction cup assembly 611 and the adsorption assembly 9 are then controlled to remove the adsorption force on the reflective plate 1 and the base plate 2, allowing the processed and laminated retro-reflector to be placed within the placement groove 3111. The output end of the translation cylinder 42 is then controlled to retract, moving the retro-reflector on the translation frame 41 and the placement table 311 into the fixed frame 31, allowing for welding of the retro-reflector to the welding member 32.

[0067] After the processing of the retro reflector is completed, the translation assembly 4 is controlled to move the placement table 311 to below the suction cup assembly 611 , and the suction cup assembly 611 adsorbs the processed retro reflector so that the processed retro reflector is quickly separated from the placement table 311 .

[0068] Then, the translation frame 41 and the placement table 311 are controlled to move into the interior of the fixed frame 31, so that the output end of the driving cylinder 60 is retracted, causing the suspension rod 61 to gradually approach the conveyor belt 65. The suction cup assembly 611 is controlled to release its suction force, so that the processed retro-reflector is placed on the placement table 311 on the conveyor belt 65, thereby quickly transferring the processed retro-reflector.

[0069] The above process realizes the loading, cleaning, processing and unloading of the retro reflector to be processed, and realizes a mechanized and fully automatic retro reflector processing flow process, thereby reducing the labor loss of manual auxiliary processing of the retro reflector and improving the processing efficiency of the retro reflector.

[0070] In addition, the reflector 1 and the base plate 2 are fixed to each other by the plug-in ring plate 21 and the plug-in ring plate 21, and the reflector 1 and the base plate 2 are welded and fixed, which increases the overall thickness of the retro reflector and thus increases the overall structural strength of the retro reflector.

[0071] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
