[0004] In implementation, after the workpiece in one of the fixed jigs is assembled with one LED precision component, it needs to be manually transferred to the next fixed jig to complete the assembly of the next LED precision component, and so on, that is, the assembly of a plurality of LED precision components on the corresponding workpiece is realized.

[0005] The above operation method is widely used, but still has certain defects and deficiencies.

[0006] Specifically, on the one hand, the corresponding workpiece needs to be continuously fed to a plurality of fixed jigs and continuously discharged from a plurality of corresponding fixed jigs, which wastes time, makes the LED precision component assembly continuity poor, the assembly speed slow, and the assembly efficiency low, and cannot effectively improve the production output of finished products per unit time, on the other hand, the continuous feeding and discharging of the corresponding workpiece makes it easy to be damaged, and the fixed jigs used to clamp the workpiece have poor adaptability, cannot clamp workpieces of different sizes and proportions in a large variable range, and have poor practicality.

[0059] The straight-line type LED precision assembly full-automatic flexible assembly line 1000 of the embodiment of the present application is described in detail below with reference to the drawings.

[0060] Referring to Figures 1 to 11As shown, the linear LED precision component full-automatic flexible assembly line 1000 provided by the embodiment of the present application comprises a mounting frame 10, a fixed slide rail 20 with multiple different assembly stations uniformly arranged from left to right, a fixed jig 30 for fixing a workpiece requiring assembly of an LED precision component, a driving mechanism 40 for driving the fixed jig 30 to move left and right to the different assembly stations, and multiple locking members 50 for positioning and locking the fixed jig 30 sliding to the front thereof.

[0061] The fixed slide rail 20 is fixed on the mounting frame 10 along the left-right direction; the fixed jig 30 is slidably arranged on the fixed slide rail 20 and connected with the driving mechanism 40; and the multiple locking members 50 are uniformly fixed on the mounting frame 10 from left to right and correspondingly located in front of the multiple assembly stations.

[0062] Based on the above, it can be clear that the present application is mainly used as a linear LED precision component full-automatic flexible assembly line 1000 in specific implementation.

[0063] Specifically, in the application of the present application, first, the workpiece requiring assembly of an LED precision component is fixed on the fixed jig 30, then the fixed jig 30 is driven by the driving mechanism 40 to move left and right to the different assembly stations, so that the mechanical hand arranged at the different assembly stations can grab and assemble the LED precision component, and in this process, the fixed jig 30 drives the workpiece clamped therein to move along the fixed slide rail 20 to each assembly station, and the locking member 50 arranged in front of each assembly station can lock and fix the workpiece, so as to fix and position the workpiece.

[0064] Through the above operation steps, it can be concluded that:

[0065] On the one hand, the present application realizes automatic conveying of the fixed jig 30 and the workpiece requiring assembly of an LED precision component therein, which can greatly save the material transfer time and greatly improve the continuity of assembly of the LED precision component, so as to make the assembly speed fast and the assembly efficiency high, effectively improve the output of finished products per unit time, and greatly reduce the workpiece damage rate, so that the present application is reliable in use.

[0066] On the other hand, when the workpiece clamped in the fixing jig 30 moves to each assembly station along the fixing slide rail 20, the locking piece 50 arranged in front of each assembly station can lock the workpiece, so as to fix and position the workpiece, so that the subsequent precise assembly of the LED precise assembly can be met, so that the application can meet the precise assembly of the high-standard LED precise assembly, and the assembly is stable and reliable.

[0067] Further, the application has good practicability and good use effect.

[0068] Further, in the technical solution, according to an embodiment of the application, the fixing jig 30 comprises a jig table 30a and a sliding block 30b suitable for being clamped to the fixing slide rail 20 and fixed to the bottom of the jig table 30a in the left-right direction; the jig table 30a is provided with a positioning groove 30a1 opened to the rear on the front side;

[0069] On this basis, each locking piece 50 comprises a positioning slide rail 501 arranged in the front-rear direction, a positioning lock block 502 slidingly installed on the positioning slide rail 501, and a positioning cylinder 503 driving the positioning lock block 502 to slide forward and backward on the positioning slide rail 501; the rear end of the positioning lock block 502 can slide backward and be clamped into the positioning groove 30a1 opposite to the position under the driving of the positioning cylinder 503, so as to position and lock the fixing jig 30 opposite to the position.

[0070] Preferably, according to an embodiment of the application, the positioning groove 30a1 is shaped as a V-shaped structure, and the rear end of the positioning lock block 502 is shaped as a sharp end, so as to be clamped into the positioning groove 30a1 in the V-shaped structure in an interference fit.

[0071] Therefore, the following can be summarized:

[0072] On the other hand, when the workpiece clamped in the fixing jig 30 moves to each assembly station along the fixing slide rail 20, the locking piece 50 arranged in front of each assembly station can lock the workpiece, so as to fix and position the workpiece, so that the subsequent precise assembly of the LED precise assembly can be met, so that the application can meet the precise assembly of the high-standard LED precise assembly, and the assembly is stable and reliable.

[0073] On the other hand, since the positioning groove 30a1 is shaped as a V-shaped structure, the rear end of the positioning lock block 502 is shaped as a sharp end to fit into the positioning groove 30a1 in the V-shaped structure in an interference fit. Thus, the V-shaped structure of the positioning groove 30a1 has a larger inner diameter at the slot opening than at the inner part, so that it has a good insertion guide function and a smooth insertion function. Even if the position of the jig table 30a with the positioning groove 30a1 opened on the front side to the rear is slightly misaligned in the left-right direction and a certain deviation is formed, after the positioning lock block 502 with the sharp end at the rear end is inserted into the positioning groove 30a1 in the V-shaped structure, the left-right position of the jig table 30a with the positioning groove 30a1 opened on the front side to the rear can be slowly corrected, so that the positioning lock block 502 with the sharp end at the rear end can finally be tightly clamped in an interference fit, to achieve accurate positioning of the left-right position, so that the fixed jig 30 positioned and clamped can be accurately positioned, to achieve excellent positioning effect, so that the assembled position of the LED precision component on the product clamped can be more accurate, so that the final assembly precision can be good.

[0074] Therefore, the above optimization design can effectively improve the use effect of the present application.

[0075] Further, in the technical solution, according to one embodiment of the present application, the driving mechanism 40 includes a conveyor belt 401 fixed to the upper part of the mounting frame 10 in the left-right direction and a driving motor 402 for driving the conveyor belt 401 to rotate counterclockwise.

[0076] The conveyor belt 401 is located at the rear side of the fixed slide rail 20, and the front end face of the conveyor belt 401 is formed with a plurality of vertically arranged teeth 4011; the rear side face of the jig table 30a is provided with a transmission tooth 30a2 for engaging the teeth 4011.

[0077] As described above, it can be understood that, in the specific implementation of the present application, the driving motor 402 drives the conveyor belt 401 to rotate counterclockwise. Since the transmission tooth 30a2 provided on the rear side face of the jig table 30a engages the corresponding teeth 4011 provided on the front side face of the conveyor belt 401, when the conveyor belt 401 rotates counterclockwise, it can drive the fixed jig 30 and the workpiece clamped in the fixed jig 30 to move from left to right along the fixed slide rail 20 to different assembly stations to achieve assembly of LED precision components at different assembly stations.

[0078] Thus, by the conveyor belt 401 as a driving member, the length of the left and right directions can be set according to the number of assembly stations, etc., the assembly stroke can be flexibly changed, and the cost of use can be greatly reduced compared with the traditional cylinder driving linear module or screw driving linear module as the driving mechanism 40.

[0079] Furthermore, according to one embodiment of the present application, the jig table 30a comprises a hollow jig seat 301, a workpiece fixing base plate 302, a first movable clamping member 303 and a second movable clamping member 304.

[0080] The workpiece fixing base plate 302 is laminated and fixed on the hollow jig seat 301, and the rear part and the right side of the upper end face are respectively vertically provided with fixed clamping jaws 3021 for clamping workpieces; the front side of the hollow jig seat 301 is provided with the positioning groove 30a1, the rear side is provided with the transmission teeth 30a2, the left side is provided with a left sliding opening 3011 penetrating the inside, and the upper part of the front side is provided with a front sliding opening 3012 penetrating the inside.

[0081] The first movable clamping member 303 is movably arranged in the hollow jig seat 301, and the left end thereof extends out of the left sliding opening 3011 and is provided with a first follow-up clamping jaw 3031 upwardly clamping workpieces; the second movable clamping member 304 is movably arranged in the hollow jig seat 301, and the front end thereof extends out of the front sliding opening 3012 and is provided with a second follow-up clamping jaw 3041 upwardly clamping workpieces.

[0082] Based on the above, it should be noted that the present application is preferably used to clamp and fix workpieces in a square structure, such as various sizes and models of mobile phone cases, etc., and when operating, the workpiece fixing base plate 302 is used to support the workpieces to be fixed, the two fixed clamping jaws 3021, the first follow-up clamping jaw 3031 and the second follow-up clamping jaw 3041 form a workpiece clamping gap between each other, the first movable clamping member 303 is moved to the left and the second movable clamping member 304 is moved forward in advance, at this time, the workpiece clamping gap can be enlarged, then the workpiece in a square structure to be clamped is placed on the workpiece fixing base plate 302, and then the first movable clamping member 303 is moved to the right to the appropriate position and the second movable clamping member 304 is moved backward to the appropriate position, at this time, the workpiece clamping gap formed between the two fixed clamping jaws 3021, the first follow-up clamping jaw 3031 and the second follow-up clamping jaw 3041 is just right to clamp the corresponding workpiece in a square structure.

[0083] And for the above, because the hollow jig base 301 is hollow inside, the first movable clamping piece 303 can move in a large range along the left-right direction, and the second movable clamping piece 304 can move in a large range along the front-back direction, so that the workpiece clamping gap can be adjusted in a large range, and workpieces of square structure with more sizes and proportions can be clamped, so that the application is practical and has good use effect.

[0084] Furthermore, in the technical solution, according to one embodiment of the application, a first limiting sliding groove 3013 is formed in the left middle part of the hollow jig base 301 along the left-right direction, a first sliding rail 3014 is fixedly arranged in the first limiting sliding groove 3013 along the left-right direction, a second limiting sliding groove 3015 is formed in the middle part of the hollow jig base 301 along the front-back direction, and a second sliding rail 3016 is fixedly arranged in the second limiting sliding groove 3015 along the front-back direction.

[0085] Moreover, the upper left part of the first limiting sliding groove 3013 communicates with the left sliding opening 3011, the upper front part of the second limiting sliding groove 3015 communicates with the front sliding opening 3012, the first movable clamping piece 303 is movably clamped in the first limiting sliding groove 3013 along the left-right direction, and the bottom of the first movable clamping piece 303 is provided with a first sliding block 3032 adapted to be clamped to the first sliding rail 3014; the second movable clamping piece 304 is movably clamped in the second limiting sliding groove 3015 along the left-right direction, and the bottom of the second movable clamping piece 304 is provided with a second sliding block 3042 adapted to be clamped to the second sliding rail 3016.

[0086] Again, according to one embodiment of the application, the first movable clamping piece 303 comprises a first movable plate 303a and a first telescopic spring 303b, and the second movable clamping piece 304 comprises a second movable plate 304a and a second telescopic spring 304b.

[0087] The left end of the first movable plate 303a extends from the left sliding opening 3011, and the first follow-up clamping jaw 3031 is arranged upward, and a first fixed block 303a1 is fixedly arranged downward on the lower bottom surface of the first movable plate 303a close to the left end, and the first telescopic spring 303b is in abutment between the left inner wall of the first limiting sliding groove 3013 and the left end surface of the first fixed block 303a1.

[0088] Moreover, the front end of the second movable plate 304a extends from the front sliding opening 3012, and the second follow-up clamping jaw 3041 is arranged upward, and a second fixed block 304a1 is fixedly arranged downward on the lower bottom surface of the second movable plate 304a close to the front end, and the second telescopic spring 304b is in abutment between the front inner wall of the second limiting sliding groove 3015 and the front end surface of the second fixed block 304a1.

[0089] Thus, the first limiting sliding groove 3013 provided can play a certain limiting and guiding role, so that the first movable plate 303a can only move left and right in it, so that the first follow-up clamping jaw 3031 on it can also only move left and right, so that the fixed clamping jaw 3021 on the right and the first follow-up clamping jaw 3031 are stable in clamping the workpiece of a square structure in the left and right directions.

[0090] Similarly, the second limiting sliding groove 3015 provided can play a certain limiting and guiding role, so that the second movable plate 304a can only move forward and backward in it, so that the second follow-up clamping jaw 3041 on it can also only move forward and backward, so that the fixed clamping jaw 3021 on the rear and the second follow-up clamping jaw 3041 are stable in clamping the workpiece of a square structure in the forward and backward directions.

[0091] Further, the first limiting sliding groove 3013, the second limiting sliding groove 3015, the first sliding rail 3014 and the second sliding rail 3016 provided play a limiting and guiding role and a sliding role, so that the application has better reliability.

[0092] It should be noted that at the beginning, the first and second extension springs 303b and 304b are in a natural state, and the workpiece clamping gap formed between the two fixed clamping jaws 3021, the first follow-up clamping jaw 3031 and the second follow-up clamping jaw 3041 is the smallest.

[0093] As can be known from the above, the first and second movable clamping members 303 and 304 are elastic members. When the first movable plate 303a of the first movable clamping member 303 is pulled to the left and the second movable plate 304a of the second movable clamping member 304 is pulled forward to expand the workpiece clamping gap and clamp a square structure workpiece of a certain size ratio, the first extension spring 303b of the first movable clamping member 303 will be in a compressed state, and the second extension spring 304b of the second movable clamping member 304 will also be in a compressed state. They can all counteract the expanded workpiece clamping gap by the reaction force generated after being compressed, so that the square structure workpiece to be clamped can be clamped tightly and not easily loosened, so as to facilitate the subsequent assembly of various parts such as integrated circuit boards, cameras and microphones on it.

[0094] In addition, according to an embodiment of the application, the first movable clamping member 303 further comprises a first stroke adjusting screw 3033 for adjusting the extension degree of the first extension spring 303b; and the second movable clamping member 304 further comprises a second stroke adjusting screw 3043 for adjusting the extension degree of the second extension spring 304b.

[0095] The hollow jig base 301 is provided with a first screw hole 3017 penetrating to the left inner wall of the first limiting sliding groove 3013 on the left side; the first stroke adjusting screw 3033 is screwed into the first screw hole 3017, and the right end of the first stroke adjusting screw 3033 is provided with a first clamping convex 30331, and the left end of the first extension spring 303b is sleeved outside the first clamping convex 30331 and abuts against the right end surface of the first stroke adjusting screw 3033.

[0096] When the first stroke adjusting screw 3033 is screwed out of the first screw hole 3017, the extension stroke of the first extension spring 303b is increased, and when the first stroke adjusting screw 3033 is screwed into the first screw hole 3017, the extension stroke of the first extension spring 303b is reduced.

[0097] The hollow jig base 301 is provided with a first screw hole 3017 penetrating to the left inner wall of the first limiting sliding groove 3013 on the left side; the first stroke adjusting screw 3033 is screwed into the first screw hole 3017, and the right end of the first stroke adjusting screw 3033 is provided with a first clamping convex 30331, and the left end of the first extension spring 303b is sleeved outside the first clamping convex 30331 and abuts against the right end surface of the first stroke adjusting screw 3033.

[0098] When the first stroke adjusting screw 3033 is screwed out of the first screw hole 3017, the extension stroke of the first extension spring 303b is increased, and when the first stroke adjusting screw 3033 is screwed into the first screw hole 3017, the extension stroke of the first extension spring 303b is reduced.

[0099] Therefore, the first stroke adjusting screw 3033 for adjusting the extension of the first extension spring 303b and the second stroke adjusting screw 3043 for adjusting the extension of the second extension spring 304b are provided, so that the extension strokes of the first extension spring 303b and the second extension spring 304b can be further increased, the gap between the fixed clamping jaws 3021, the first follower clamping jaw 3031 and the second follower clamping jaw 3041 can be further increased, and the square structure workpiece of a larger size can be clamped without changing the overall circumference of the application, so that the application is more practical and effective.

[0100] It needs to be added that, according to one embodiment of the present application, the right end of the first limiting sliding groove 3013 is communicated with the left middle part of the second limiting sliding groove 3015; the left middle part of the second movable plate 304a is provided with a linkage groove 304a2, and the linkage groove 304a2 is provided with a linkage inclined surface 304a3 which is inclined to the left rear; the right middle part of the first movable plate 303a is provided with a rotating groove 303a2 which is opened to the left, and the rotating groove 303a2 is horizontally fixed with a rotating wheel 303a3 which abuts against the linkage inclined surface 304a3;

[0101] When the second movable plate 304a is controlled to move forward, the linkage inclined surface 304a3 pushes the rotating wheel 303a3 forward to drive the first movable plate 303a to move leftward synchronously.

[0102] Therefore, when the present application is used, only the second movable plate 304a needs to be pulled forward, which can push the rotating wheel 303a3 forward through the linkage inclined surface 304a3 to drive the first movable plate 303a to move leftward synchronously, so that the second follow-up clamping jaw 3041 and the first linkage clamping jaw can be opened synchronously to facilitate the clamping of the square structure workpiece which needs to be clamped on the workpiece fixing base plate 302. In the related operation process, only the second movable plate 304a needs to be controlled to move forward, and the first movable plate 303a does not need to be pulled leftward by hand, so that the operation is time-saving and labor-saving, and the working burden and fatigue of the operator can be greatly reduced.

[0103] It needs to be added that, in specific implementation, according to one embodiment of the present application, the inner surface of the two fixed clamping jaws 3021 is respectively inclined upward and inward to form a fixed inclined surface 30211; the inner surface of the upper part of the first follow-up clamping jaw 3031 is inclined upward and inward to form a first follow-up clamping inclined surface 30311; and the inner surface of the upper part of the second follow-up clamping jaw 3041 is inclined upward and inward to form a second follow-up clamping inclined surface 30411.

[0104] Therefore, when the square structure workpiece is fixed between the two fixed clamping jaws 3021, the first follow-up clamping jaw 3031 and the second follow-up clamping jaw 3041 to form a workpiece clamping gap, the two fixed inclined surfaces 30211, the first follow-up clamping inclined surface 30311 and the second follow-up clamping inclined surface 30411 can well clamp the square structure workpiece from the upper part, so that the square structure workpiece is not easy to be dislodged in the up-down direction, and the reliability of the present application is optimized.

[0105] And, according to one embodiment of the present application, the workpiece needs to be formed into a flat square structure, and preferably various sizes of mobile phone shells and the like.

[0106] In summary, the straight-line type LED precision assembly full-automatic flexible assembly line 1000 provided by the application can realize automatic conveying of the fixing jig 30 and the workpiece needing to be assembled with the LED precision assembly in the fixing jig 30, so that the conveying time can be greatly saved, the continuity of the LED precision assembly can be greatly improved, the assembly speed is fast, the assembly efficiency is high, the production yield of finished products can be effectively improved in unit time, and the workpiece damage rate can be greatly reduced, so that the application is reliable in use.

[0107] In addition, when the workpiece clamped in the fixing jig 30 moves along the fixing slide rail 20 to each assembly station, the workpiece can be locked and fixed by the locking piece 50 arranged in front of each assembly station, so as to be fixed and positioned, so that the subsequent precision assembly requirements of the LED precision assembly can be met, so that the application can meet the high-standard precision assembly of the LED precision assembly, and the assembly is stable and reliable.

[0108] Meanwhile, since the hollow jig seat 301 is of a hollow structure, the first movable clamping piece 303 can move in a large range in the left-right direction, and the second movable clamping piece 304 can also move in a large range in the front-rear direction, so that the workpiece clamping gap can be adjusted in a large range, so that workpieces of square structures of more size ratios can be clamped and fixed, so that the application is practical and has good use effect.

[0109] Therefore, the application is optimized and designed, and has excellent use effect as a whole, so that the application will be very popular and will be popularized and applied.
