[0035] Please refer to Figures 1 - 10, this application provides a bracket loading machine 10, which includes a frame 800 and a bracket picking mechanism 300 and a bracket transfer mechanism 400 arranged on the frame 800.

[0036] In an alternative embodiment, the frame 800 includes a first support plate 100 and a second support plate 200. The first support plate 100 and the second support plate 200 are spaced apart and form a placement space 500.

[0037] As Figure 9 and Figure 10 shown, in an alternative embodiment, the material trolley 600 includes a vehicle frame 610, a positioning groove 620 arranged on the vehicle frame 610, and a positioning hole 630 located on the positioning groove 620. Optionally, the vehicle frame 610 can be used to carry a tray 640, and the tray 640 can be used to place brackets 650. In an alternative embodiment, a plurality of trays 640 are detachably stacked on the vehicle frame 610, and a plurality of brackets 650 can be arranged in an array on the tray 640.

[0038] In an alternative embodiment, the bracket picking mechanism 300 can be specifically mounted on the first support plate 100 and the second support plate 200, that is, the bracket picking mechanism 300 is integrally arranged across the first support plate 100 and the second support plate 200, and the bracket transfer mechanism 400 is arranged on the first support plate 100.

[0039] In an alternative scenario, the bracket picking mechanism 300 can move back and forth above the entire placement space 500 and the bracket transfer mechanism 400 and can penetrate into the placement space 500 to pick up the brackets 650 or trays 640 on the material trolley 500, and place the brackets 650 on the bracket transfer mechanism 400 and / or place the trays 640 in the vacant area 520 in the placement space 500.

[0040] Optionally, the bracket picking mechanism 300 can move back and forth between the first support plate 100 and the second support plate 200, so as to pick up the brackets 650 on the material trolley 600 located between the first support plate 100 and the second support plate 200, drive the brackets 650 above the bracket transfer mechanism 400, and then the bracket picking mechanism 300 further places the brackets 650 on the bracket transfer mechanism 400. Subsequently, the bracket transfer mechanism 400 transfers the brackets 650 so that the brackets 650 reach the next station.

[0041] AsFigure 8 As shown in the figure, the bracket transfer mechanism 400 includes a storage component 410, a lateral material transfer mechanism 420, and a clamping component 430. The storage component 410 is arranged on the first support plate 100 and is used to receive the brackets 650 placed by the bracket material taking mechanism 300; the lateral material transfer mechanism 420 is located at one end of the storage component 410 and includes a third translation output end 421; the clamping component 430 is arranged on the third translation output end 421 and is used to pick up the brackets 650 on the storage component 410 and move them to the next station under the drive of the lateral material transfer mechanism 420.

[0042] In the above embodiment, by providing a bracket loading machine 10, the bracket loading machine 10 includes a placement space 500 for placing the material trolley 600, and includes a bracket material taking mechanism 300 and a bracket transfer mechanism 400. The bracket material taking mechanism 300 can pick up the brackets 650 on the material trolley 600 and place them on the bracket transfer mechanism 400, and the bracket transfer mechanism 400 transfers the brackets, so that the automatic transfer of the brackets 650 can be realized. Compared with the manual method,

[0043] This application can greatly improve the automation, thereby improving the efficiency, and can ensure that the brackets 650 can reach the next station according to the preset pose, effectively improving the yield rate of subsequent processing.

[0044] As Figure 1 、 Figure 2 and Figure 3 shown in the figure, the bracket material taking component 300 includes a first translation component 310, a second translation component 320, a lifting component 330, and a material taking component 340. The first translation component 310 includes a first translation output end 311, the second translation component 320 is arranged on the first translation output end 311 and includes a second translation output end 321, the lifting component 330 is arranged on the second translation output end 321 and includes a lifting output end 331, and the material taking component 340 is arranged on the lifting output end 331

[0045] and can be used to pick up and unload the brackets 640.

[0046] Optionally, the lifting component 330 can specifically be a lifting cylinder, which is not limited here.

[0047] Among them, the first translation component 310 is used to drive the second translation component 320, the lifting component 330, and the material taking component 340 as a whole to move along a first direction parallel to the direction of the distance between the first support plate 100 and the second support plate 200. That is, the first translation component 310 can drive the second translation component 320, the lifting component 330, and the material taking component 340 as a whole to move back and forth between the first support plate 100 and the second support plate 200 through the first translation output end 311. The second translation component 320 is used to drive the lifting component 330 and the material taking component 340 as a whole to move along a second direction perpendicular to the first direction. Optionally, both the first direction and the second direction are directions parallel to the horizontal plane, and the lifting component 330 is used to drive the material taking component 340 to move along a third direction perpendicular to the first direction and the second direction. Optionally, the third direction is the direction of gravity, that is, the lifting component 330 can drive the material taking component 340 to lift. Through the cooperation of the first moving component 310, the second moving component, and the lifting component 330, the material taking component 340 can be driven to move in three mutually perpendicular directions, and thus the bracket 650 within the moving range (i.e., the placement space 500) of the first moving component 310, the second moving component, and the lifting component 330 can be taken. And then drive the bracket 650 to move to be placed on the bracket transfer mechanism 400.

[0048] As Figures 5 - 7 shown, the material taking component 340 includes two material suction bars 341, a material discharging block 342, and a material discharging cylinder 343. The two material suction bars 341 are arranged at intervals, and the material discharging block 342 is arranged between the two material suction bars 341 and fixed on the lifting output end 331.

[0049] Optionally, the material suction bar 341 includes a first surface 3411 on the side away from the second translation component 320 and a second surface 3412 opposite to the first surface 3411, and a magnetic attraction block 344 is arranged on the first surface 3411. The material discharging block 342 includes a third surface 3421 on the side away from the second translation component 320 and a fourth surface 3422 opposite to the third surface 3421.

[0050] The material discharging cylinder 343 is arranged on the material discharging block 342, specifically on the fourth surface 3422 of the material discharging block 342. The material discharging cylinder 343 includes a material discharging output end 3431, and the material discharging output end 3431 is connected to the two material suction bars 341. Optionally, driven by the material discharging output end 3431 of the material discharging cylinder 343, the two material suction bars 341 can move relative to the material discharging block 342 along the pushing direction of the material discharging output end 3431.

[0051] In a specific scenario, the material discharging cylinder 343 can be used to drive two material suction bars 341 to move relative to the material discharging block 342 so that the first surface 3411 and the third surface 3421 are flush. Specifically, the material discharging cylinder 343 can drive the two material suction bars 341 to descend relative to the material discharging block 342 so that the first surface 3411 and the third surface 3421 are flush, thereby facilitating the magnetic suction block 344 on the material suction bar 341 to adsorb the bracket 650 to complete material taking. The material discharging cylinder 343 further drives the material suction bar 341 to move relative to the material discharging block 342. Specifically, it can drive the material suction bar 341 to rise relative to the material discharging block 342 so that the material discharging block 342 protrudes relatively from the first surface 3411, that is, the material discharging block 342 can abut against the bracket 650 to complete material discharging.

[0052] Optionally, since the bracket 650 has a certain length, by cooperating the above magnetic suction method and material discharging method, on the one hand, it can effectively and stably take and discharge the bracket 650, and compared with using multiple clamping cylinders, it has better accuracy and lower cost.

[0053] As Figure 6 shown, a plurality of convex portions 3413 are provided on the opposite sides of the two material suction bars 341, and the plurality of convex portions 3413 are arranged at intervals, and the magnetic suction blocks 344 are arranged on the convex portions 3413, and a plurality of grooves 3423 matching with the plurality of convex portions 3413 are provided on both sides of the material discharging block 342.

[0054] Optionally, through the mutual cooperation of the convex portions 3413 and the grooves 3423, the two material suction bars 341 and the material discharging block 342 can have better stability when moving relative to each other.

[0055] As Figure 5 shown, the material discharging block 342 includes a first sub-block 3424 and a second sub-block 3425 arranged in a "T" shape. The first sub-block 3424 is embedded between the intervals of the two material suction bars 341, and the width of the second sub-block 3425 is greater than the width of the first sub-block 3424. Optionally, the second sub-block 3425 includes an upper sub-board 3426 spaced from the first sub-block 3424, and both ends of the upper sub-board 3426 are fixedly connected to the first sub-block 3424 through connecting plates 3428.

[0056] Optionally, the material taking assembly 340 further includes a connecting block 347 that connects two material suction bars 341. The connecting block 347 is located between the upper sub-board 3426 and the first sub-block 3424 and can move back and forth between the upper sub-board 3426 and the first sub-block 3424. The cylinder seat of the material discharging cylinder 343 is arranged on the upper sub-board 3426, and the material discharging output end 3431 of the material discharging cylinder 343 can penetrate the upper sub-board 3426 and be fixed to the connecting block 347. Thus, the material discharging output end 3431 of the material discharging cylinder 343 can drive the connecting block 347 to move relative to the upper sub-board 3426, and further drive the two material suction bars 341 to move relative to the material discharging block 342.

[0057] Through the above design, the entire material taking assembly 340 is compact and practical, with the advantages of small volume and complete functions, and the overall structural design has strong stability.

[0058] As Figure 6 shown, the material taking assembly 340 further includes connecting bars 348 respectively located at both ends of the two material suction bars 341. One connecting bar 348 is arranged at each end of the two material suction bars 341. Claw cylinders 349 are arranged at both ends of the connecting bar 348. The four claw cylinders 349 are used to cooperate to grab the material tray 640.

[0059] In an alternative embodiment, the placement space 500 further includes an empty area 520. When the brackets 650 in the material tray 640 on the upper layer of the material trolley 600 are taken out, the material taking assembly 340 can also grab the four corners of the material tray 640 through the four claw cylinders 349, so as to complete the clamping of the empty material tray 640. Subsequently, the first translation assembly 310, the second translation assembly 320 and the lifting assembly 330 cooperate to drive the material taking assembly 340 to place the empty material tray 640 into the empty area 520, thereby realizing fully automatic feeding without manual replacement of different material trays 640, and can also greatly increase the number of brackets 650 that a single material trolley 600 can carry. The production efficiency is effectively improved.

[0060] As Figure 1 shown, the first translation assembly 310 further includes a first guide rail 312 and a second guide rail 313 mounted on the frame 800. Specifically, the first guide rail 312 and the second guide rail 313 are mounted on the first support plate 100 and the second support plate 200, and the first translation output end 311 is slidably arranged on the first guide rail 312.

[0061] Optionally, the first guide rail 312 is fixed to one end of the first support plate 100 and the second support plate 200 respectively, and the second guide rail 313 is fixed to the other end of the first support plate 100 and the second support plate 200 respectively. The first support plate 100, the second support plate 200, the first guide rail 312, and the second guide rail 313 enclose the placement area 500 as a whole.

[0062] The second translation assembly 320 further includes a third guide rail 322. One end of the third guide rail 322 is disposed on the first translation output end 311, the other end is slidably disposed on the second guide rail 312, and the second translation output end 321 is slidably disposed on the third guide rail 322.

[0063] Optionally, by respectively disposing the third guide rail 322 of the second translation assembly 320 on the first translation output end 311 and the second guide rail 312, the stability during the entire sliding process can be effectively enhanced.

[0064] In an alternative embodiment, sensors 3121 are respectively disposed at both ends of the first guide rail 312. The distance sensors 3121 are used to detect information of the second translation assembly 320 and / or the material taking assembly 340 and / or the lifting assembly 330. When the sensors 3121 detect the second translation assembly 320 and / or the material taking assembly 340 and / or the lifting assembly 330, the first translation output end 311 is controlled to stop, so as to prevent the second translation assembly 320, the material taking assembly 340, and the lifting assembly 330 from detaching from the entire first guide rail 312, thereby improving safety.

[0065] In an alternative embodiment, the sensor 3121 may specifically be a distance sensor. The distance sensor can be used to emit detection light in the direction of the second guide rail 312. When the second translation assembly 320 and / or the material taking assembly 340 and / or the lifting assembly 330 block the detection light, the distance detected by the sensor 3121 becomes shorter, that is, it can be considered that the second translation assembly 320 and / or the material taking assembly 340 and / or the lifting assembly 330 are detected.

[0066] Optionally, the clamping member 430 may specifically be a clamping cylinder, which is not limited herein.

[0067] Such as Figure 8As shown, the storage assembly 410 includes a support frame 411, a base plate 412, a slide rail 413, a slider 414, a lateral pusher 415, and a vertical pusher 416. The support frame 411 includes a support block 4111 and side plates 4112 disposed on both sides of the support block 4111, and the side plates 4112 are provided with an embedding groove 4113 for embedding the bracket 640. The base plate 412 is disposed on the support block 4111; the slide rail 413 is disposed on the base plate 412; and the slider 414 is slidably disposed on the slide rail 413. The lateral pusher 415 is disposed on the base plate 412, and the lateral push output end 4151 of the lateral pusher 415 is connected to the slider 414; and the vertical pusher 416 includes a vertical push output end 4161 connected to the base plate 412.

[0068] In an optional scenario, the slider 414 and the embedded groove 4113 cooperate to receive the bracket 650 placed by the bracket material taking mechanism 300. Optionally, by setting the embedded groove 4113, on the one hand, the bracket 650 can be prevented from shaking on the slider 414, and on the other hand, it is conducive to the repositioning and position adjustment of the bracket 650, so that the bracket 650 can be placed on the slider 414 according to the preset position. The vertical pusher 416 is used to drive the substrate 412, the slide rail 413, the slider 414, the horizontal pusher 416 and the bracket 650 to rise as a whole, so that the bracket 640 is released from the engagement with the embedded groove 4113. Subsequently, the horizontal pusher 416 is used to push the slider 414 and the bracket 650 as a whole to move along the second direction so that the bracket 650 can be located below the clamping member 430. This is to facilitate the clamping member 430 to clamp the bracket 650.

[0069] like Figure 1 As shown, the storage assembly 410 also includes a distance sensor 418 arranged on the substrate 412, and the distance sensor 418 is used to emit a detection light parallel to the second direction, and the distance sensor 418 is used to detect the positive and negative information of the support 650 placed on the storage assembly 410. Optionally, the support 650 is provided with a through hole, and if the position where the support 650 is placed is positive, the detection light of the distance sensor 418 can penetrate the through hole on the support 650 and hit the side wall of the support transfer mechanism 400, with a longer length. If the position where the support 650 is placed is negative, the detection light of the distance sensor 418 directly hits the side wall of the support 650, namely, has a shorter length, and the distance information obtained by the distance sensor 418 can effectively and quickly determine the positive and negative information where the support 650 is placed. Optionally, the support transfer mechanism 400 further includes a rotating assembly 440 , which is fixed to the third translation output end 421 , and the rotating assembly 440 further includes a rotating output end 441 connected to the clamping member 430 .

[0070] In an optional scenario, if the positive / negative information of the bracket 650 detected by the distance sensor 418 is positive, the third translation output end 421 directly drives the material clamping part 430 and the bracket 650 to translate to the next station. If the positive / negative information of the bracket 650 detected by the distance sensor 418 is negative, the rotation output end 441 of the rotation assembly 440 drives the material clamping part 430 and the bracket 650 to rotate, and then the third translation output end 421 drives the material clamping part 430 and the bracket 650 to translate to the next station. Thus, it can be ensured that the brackets reaching the next station all maintain the same placement direction.

[0071] As Figure 3 shown, the bracket loader 10 further includes a fixing strip 700 disposed between the first support plate 100 and the second support plate 200. Optionally, the fixing strip 700 is located below the second guide rail 313. A proximity sensor 720 and a positioning assembly 710 are provided on the fixing strip 700. The proximity sensor 720 is used to detect the distance information between the material trolley 600 and the positioning assembly 720, and the positioning assembly 710 is used to fix the material trolley 600 in the placement space 500 according to the distance information.

[0072] The positioning assembly 720 includes a positioning bump 711, a driving cylinder 712, and a positioning pin 713 disposed at the output end of the driving cylinder 712; the material trolley 600 includes a positioning groove 620 that cooperates with the positioning bump 711, and the positioning groove 620 includes a positioning hole 630 for cooperating with the positioning pin 713.

[0073] Optionally, if the distance information indicates that the distance between the material trolley 600 and the positioning assembly 720 is less than a threshold value (almost in contact), the driving cylinder 712 drives the positioning pin 713 to descend into the positioning hole 630, thereby firmly fixing the material trolley 600 in the placement space 500.

[0074] Discuss the specific working principle based on the above structure:

[0075] After the material trolley 600 finishes loading the bracket 650 and enters the placement space 500, when the positioning groove 620 of the material trolley 600 is aligned with the positioning bump 711 of the bracket loader 10, the proximity sensor 710 detects the relevant proximity information, and then controls the driving cylinder 712 to drive the positioning pin 713 to engage with the positioning hole 630 to fix the material trolley 600 in the placement space 500. Optionally, multiple material trolleys 600 can be neatly fixed in the placement space 500 at the same time, and an empty area 520 can be left in the placement space 500.

[0076] Subsequently, the first translation component 310 and the second translation component 320 cooperate to drive the lifting component 330 and the material taking component 340 to move above the support 650 of the material trolley 600. Subsequently, the lifting component 330 drives the material taking component 340 to descend to pick up the support 640. Then, the lifting component 330 drives the material taking component 340 and the support 640 to rise, and under the cooperation of the first translation component 310 and the second translation component 320, they move above the storage component 410. Then, the lifting component 330 drives the material taking component 340 and the support 640 to descend to place the support 650 on the storage component 410, specifically on the slider 414 and the embedding groove 4113. The material taking and discharging processes of the material taking component 340 have been specifically described in the above embodiments and will not be elaborated here.

[0077] Subsequently, the vertical pushing member 416 is used to drive the substrate 412, the slide rail 413, the slider 414, the horizontal pushing member 416, and the support 650 to rise as a whole, so that the support 640 is disengaged from the engagement with the embedding groove 4113. Then, the horizontal pushing member 416 is used to push the slider 414 and the support 650 to move along the second direction as a whole so that the support 650 can be located below the clamping member 430.

[0078] Subsequently, the clamping member 430 clamps the support 650, and based on the judgment of the distance sensor 418, it is determined whether the support 650 needs to be rotated by the rotating component 440. If not, the support 650 is directly driven to the next working station by the third translation output end 421. If so, the support 650 is rotated by the rotating component 440 and then the support 650 is driven to the next working station by the third translation output end 421.

[0079] In other scenarios, if all the supports 650 on a tray 640 are taken away, the material taking component 340 can be used to clamp the empty tray 640 and then take it to the empty area 520.

[0080] In the above embodiments, the support loading machine 10 provided by the present application can automatically pick up, discharge, and transfer the supports through the cooperation of various components or elements, and can ensure the position of the output supports during the transfer process, thereby greatly improving the qualified rate and efficiency and realizing intelligent and automated production.

[0081] The present application also provides a material trolley 600, which includes a vehicle frame 610, a positioning groove 620, and a positioning hole 630. The positioning groove 620 is arranged on the vehicle frame 610, and the positioning hole 630 is located on the positioning groove 620. The vehicle frame 610 is used to place the tray 630.

[0082] The present application further provides an automatic feeding method, which is applied to the bracket feeding machine 10 described in any one of the above, and the method includes:

[0083] First, the material trolley enters the frame and is fixed in the placement space of the frame. The material trolley includes sequentially stacked trays, and brackets are placed on the trays;

[0084] Second, the bracket picking mechanism picks up the brackets on the material trolley located in the placement space;

[0085] Third, the bracket picking mechanism places the brackets on the bracket transfer mechanism;

[0086] Fourth, the bracket transfer mechanism moves the brackets to the next station;

[0087] Fifth, the bracket picking mechanism picks up the empty trays on the material trolley and transfers them to the empty area in the placement space;

[0088] Sixth, after all the trays and brackets on the material trolley are transferred, the material trolley releases its fixation with the frame and disengages from the placement space.

[0089] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent results or equivalent process transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the present invention.
