DETAILED DESCRIPTION

[0034] In order to more clearly illustrate the technical solutions of the embodiments of the present application or the prior art, the present application will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art.

It should be noted that the description of these embodiments is used to help understand the present application, but does not constitute a limitation on the present application.

[0036] In some examples, some embodiments belong to the prior art or conventional technology, and therefore are not described or not described in detail.

[0037] In addition, the technical features described herein, or the steps in all the disclosed methods or processes, can be combined in any suitable manner in one or more embodiments, except for mutually exclusive features and / or steps. It is easy for those skilled in the art to understand that the order of steps or operations of the methods related to the embodiments provided herein can also be changed. Any order in the drawings and embodiments is only for illustration of use and does not imply that a certain order is required, unless it is explicitly stated that a certain order is required.

[0038] The serial numbers of components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in this application include direct and indirect connection (coupling) under reasonable circumstances (not self-contradictory circumstances).

[0039] As shown in Figure 1 The feeding device of the automatic assembly system of the embodiment includes an input conveyor belt 320, an output conveyor belt 310, a tray positioning assembly 330, a supporting component 340, a transfer module 100 and a manipulator 200. The input conveyor belt 320 is used to convey a stack of trays 500 containing materials. The output conveyor belt 310 is used to send out the empty trays 500. The supporting component 340 cooperates with the tray positioning assembly 330 to realize the separation of a stack of trays 500 into single trays 500. The transfer module 100 is used for precise positioning of the materials, ensuring that the manipulator 200 on the main line can accurately pick up the materials and accurately install the materials to the components on the main line. The manipulator 200 is used to pick up the materials in the separated trays 500 and place them in the transfer module 100 for secondary positioning. In the present embodiment, as shown in Figure 2 and 3 The tray positioning assembly 330 can include two spaced supporting telescopic components 331. The supporting telescopic components 331 have supporting parts 3311 for supporting the trays 500. When the interval between the two supporting parts 3311 is at a first interval 3315, the supporting component 340 is used to lift a stack of trays 500 at the output end of the input conveyor belt 320 and make the supporting parts 3311 located between the skirts 510 of the two uppermost trays 500 in the stack. When the interval between the two supporting parts 3311 is at a second interval 3316, the supporting component 340 is used to lower the stack of trays 500 so that the skirts 510 of the uppermost tray 500 are supported on the supporting parts 3311. At the same time, the supporting component 340 continues to descend, and under the action of gravity, the uppermost tray 500 in the stack is separated from the lower tray 500, thereby realizing the separation of the trays.

[0040] The support part 3311 can be in the form of a conveyor belt, and when the tray 500 on the support part 3311 is emptied, the conveyor belt transports the emptied tray 500 to the discharge conveyor belt 310 and the emptied tray 500 is discharged by the discharge conveyor belt 310. As shown in Figure 2 and 3 The support telescopic part 331 can include an L-shaped bracket 3312 and a second telescopic cylinder 3313 for driving the L-shaped bracket 3312 to telescope along the vertical direction of the discharge conveyor belt 310. The opposite sides of the L-shaped bracket 3312 of the two support telescopic parts 331 are fixed with support bars 3314, and the support bars 3314 are the support part 3311. As shown in Figure 1 The feeding device of the automatic assembly system can further include a tray pushing mechanism 350 for pushing the empty tray 500 at the tray positioning assembly 330 into the discharge conveyor belt 310. After the robot 200 takes the material in the tray 500, the empty tray 500 is pushed into the discharge conveyor belt 310. At the same time, the empty tray 500 can be quickly pushed into the discharge conveyor belt 310 by the tray pushing mechanism 350, thereby improving the efficiency. The L-shaped bracket 3312 is provided to avoid interference with the positioning telescopic part 332 described below. As shown in Figure 2 and 3 The cylinder body of the second telescopic cylinder 3313 is fixed to the machine table 400, the piston rod of the second telescopic cylinder 3313 is connected with the horizontal arm of the L-shaped bracket 3312, the horizontal arm of the L-shaped bracket 3312 is installed on the machine table 400 through a linear guide rail, and the vertical arm of the L-shaped bracket 3312 is installed with the support bar 3314.

[0041] In some specific embodiments, as shown in Figure 4 The tray pushing mechanism 350 can include a pawl 351 and a driving part 352 for driving the pawl 351 to reciprocate along the conveying direction of the discharge conveyor belt 310. When the tray pushing mechanism 350 is in standby mode, the interval between the pawl 351 and the feeding end of the discharge conveyor belt 310 is greater than the size of the tray 500 in the conveying direction of the discharge conveyor belt 310. When the tray pushing mechanism 350 is in working mode, the driving part 352 is used to drive the pawl 351 to move along the conveying direction of the discharge conveyor belt 310 and push the empty tray 500 at the tray positioning assembly 330 to the discharge conveyor belt 310. In some specific embodiments, as shown in Figure 4 The driving part 352 is a third single-axis robot 354, and the third robot is located on one side of the tray positioning assembly 330 and extends along the conveying direction of the discharge conveyor belt 310. The pawl 351 is L-shaped, the vertical arm of the pawl 351 is fixed to the output end of the third single-axis robot 354, the horizontal arm of the pawl 351 extends along the vertical direction of the conveying direction of the discharge conveyor belt 310, and the two ends of the horizontal arm of the pawl 351 extend downward and form pawls 3511.

[0042] In some specific embodiments, as shown in Figure 4As shown, the pusher claw 351 is vertically telescoped at the output end of the driving component 352, specifically, the output end of the driving component 352 is fixed with a seventh telescopic cylinder 353, and the pusher claw 351 is fixed to the piston rod of the seventh telescopic cylinder 353, when the pusher disc mechanism 350 is in the working mode, the pusher claw 351 is in the extended state; when the pusher disc mechanism 350 is in the reset mode, the pusher claw 351 is in the retracted state, and the driving component 352 is used to drive the pusher claw 351 to move in the direction opposite to the conveying direction of the discharge conveying belt 310. By setting the telescopic pusher claw 351, when the pusher disc mechanism 350 is reset, the pusher claw 351 is retracted, so as not to interfere with the raised tray 500, that is, the pusher disc mechanism 350 is reset and the tray supporting component 340 lifts the tray 500 at the same time, so as to improve the efficiency.

[0043] In some embodiments, as shown in Figure 1 As shown, the discharge conveying belt 310, the feeding conveying belt 320, the tray positioning assembly 330 and the tray supporting component 340 form the tray 500 circulation assembly 300, and the tray 500 circulation assembly 300 is provided with two; the mechanical arm 200 is located at the center of the area surrounded by the transfer module 100 and the two tray positioning assemblies 330, that is, the transfer module 100 and the two tray positioning assemblies 330 are located on the same circumference with the mechanical arm 200 as the center, compared with other layouts, the material transfer is faster.

[0044] In some embodiments, as shown in Figure 1 and 5 As shown, the tray supporting component 340 can include a supporting bracket 341, the supporting bracket 341 is fixed to the output end of the first single-axis mechanical arm 360, the first single-axis mechanical arm 360 is vertically arranged and arranged at the end of the discharge end of the feeding conveying belt 320, so that the supporting bracket 341 moves within the vertical length range of the first single-axis mechanical arm 360, avoiding being too high in the vertical direction, thereby facilitating personnel to take and place the tray 500 at the discharge end of the discharge conveying belt 310 and the feeding end of the feeding conveying belt 320. As shown in Figure 5 As shown, the supporting bracket 341 can be provided in an L shape, the vertical arm of the supporting bracket 341 is fixed to the output end of the first single-axis mechanical arm 360, and the horizontal arm of the supporting bracket 341 extends in the direction opposite to the conveying direction of the feeding conveying belt 320. As shown in Figure 1 As shown, the feeding conveying belt 320 is in the form of double-row synchronous belt, and the supporting bracket 341 is located between the two rows of synchronous belts. Obviously, the feeding conveying belt 320 can also be a relatively wide flat belt, and the corresponding supporting bracket 341 is provided with a notch in the middle to avoid the feeding conveying belt 320.

[0045] In some embodiments, as shown in Figure 1As shown, the transfer module 100 can include a second single-axis mechanical arm 110 and a positioning jig 120 arranged at the output end of the second single-axis mechanical arm 110, the positioning jig 120 being used for positioning at least one material. The positioning jig 120 can be provided with a profiled groove matching the gap of the material according to the shape of the material, and the slot opening of the profiled groove is provided with a large chamfer to facilitate the placement of the material.

[0046] The end tool 210 of the robot 200 can be selected according to the material. For example, the end tool 210 of the robot 200 can be a vacuum suction head 212. In order to prevent the material from tilting, at least three vacuum suction heads 212 are arranged, and the center of gravity of the material is located within the polygon formed by the plurality of vacuum suction heads 212, and at least three positioning columns 211 are arranged. After the material is sucked by the vacuum suction head 212, it is abutted against the end of the positioning column 211 to keep horizontal. Figure 6 As shown, in this embodiment, four vacuum suction heads 212 and four positioning columns 211 are arranged.

[0047] In some embodiments, as shown in Figure 2 and 3 The tray positioning assembly 330 can further include two positioning telescopic components 332 arranged at intervals; both of the two positioning telescopic components 332 are located above the two supporting telescopic components 331; the telescopic direction of the positioning telescopic component 332 is the same as that of the supporting telescopic component 331; as shown in Figure 7 The positioning telescopic component 332 has a first positioning reference 3321 extending along the conveying direction of the discharge conveying belt 310; both ends of the first positioning reference 3321 have a second positioning reference 3322 extending perpendicularly to the conveying direction of the discharge conveying belt 310; when the tray positioning assembly 330 is in the positioning state, the area enclosed by the first positioning reference 3321 and the second positioning reference 3322 of the two positioning telescopic components 332 is adapted to the outer contour of the tray 500. By arranging the positioning telescopic component 332, the tray 500 is accurately positioned, thereby facilitating the robot 200 to grasp the material in the tray 500.

[0048] In some embodiments, as shown in Figure 2 and 7 The positioning telescopic component 332 includes a first telescopic plate 3323 and a first telescopic cylinder 3324 driving the first telescopic plate 3323 to telescopically extend perpendicularly to the conveying direction of the discharge conveying belt 310; the first telescopic plate 3323 extends along the conveying direction of the discharge conveying belt 310, and both ends of the first telescopic plate 3323 are fixed with L-shaped blocks 3325; the two L-shaped blocks 3325 are arranged oppositely, and the edges of the two L-shaped blocks 3325 located on the same line are the first positioning reference 3321, and the other edges of the two L-shaped blocks 3325 are the second positioning reference 3322. As shown in Figure 2As shown, the cylinder body of the first telescopic cylinder 3324 is fixed to the machine table 400, the piston rod of the first telescopic cylinder 3324 is connected to the first telescopic plate 3323, and the first telescopic plate 3323 is installed on the machine table 400 through a linear guide rail. It can be understood that the edge of the L-shaped block 3325 of the second positioning reference 3322 has a chamfer, so that the tray 500 is automatically aligned during telescoping.

[0049] In some embodiments, as shown in Figure 8 As shown, the discharge conveyor belt 310 is located directly above the feeding conveyor belt 320, and the conveying directions of the discharge conveyor belt 310 and the feeding conveyor belt 320 are parallel and opposite; it should be noted that the driving motor driving the discharge conveyor belt 310 is located on the side of the discharge conveyor belt 310, and the driving motor driving the feeding conveyor belt 320 is located on the side of the feeding conveyor belt 320; the vertical spacing between the discharge conveyor belt 310 and the feeding conveyor belt 320 is a third spacing 313, which is used to limit the number of trays 500 in the same stack of trays 500 on the feeding conveyor belt 320, so as to avoid the situation that too many trays 500 in a stack of trays 500 cause the lower trays 500 to be too tightly clamped to be separated. Because the trays 500 are mostly plastic products and have relatively large elasticity, if too many trays 500 are stacked, the lower trays 500 in the stack are pressed too tightly under the gravity of the upper trays 500 and the material, which may result in the inability to separate the trays 500 and the material by relying on the self-weight of the trays 500 and the material. Moreover, because the skirt 510 of the tray 500 is relatively thin, it is difficult to separate the trays 500 even by applying external force when the trays 500 are pressed too tightly. Therefore, the third spacing 313 is used to limit the number of trays 500 in the same stack of trays 500, so that if the height of a stack of trays 500 exceeds the third spacing 313, the stack of trays 500 is blocked by the discharge conveyor belt 310, thereby achieving the purpose of limiting the number of trays 500 in the same stack of trays 500 on the feeding conveyor belt 320, and facilitating the cooperation between the supporting component 340 and the tray positioning assembly 330 to complete the separation of the trays 500.

[0050] In some embodiments, as shown in Figure 1 As shown, the feeding conveyor belt 320 is provided with first baffles 321 on both sides, and a first guide channel 322 for guiding the trays 500 is formed between the two first baffles 321, so as to avoid the trays 500 from being skewed and affecting the subsequent positioning of the trays 500.

[0051] In some embodiments, as shown in Figure 1 As shown, the discharge conveyor belt 310 is provided with second baffles 311 on both sides, and a second guide channel 312 for guiding the trays 500 is formed between the two second baffles 311, so as to avoid the trays 500 from being skewed and facilitate the taking of the trays 500.

[0052] In some embodiments, as shown in Figure 8As shown, the outfeed conveyor 310 is located directly above the infeed conveyor 320, the conveying directions of the outfeed conveyor 310 and the infeed conveyor 320 are parallel and opposite, the infeed end of the infeed conveyor 320 extends beyond the outfeed end of the outfeed conveyor 310, the distance between the infeed end of the infeed conveyor 320 and the outfeed end of the outfeed conveyor 310 in the conveying direction is D, the distance between the outfeed end of the infeed conveyor 320 and the infeed end of the outfeed conveyor 310 in the conveying direction is L, and the size of the tray 500 in the conveying direction is d; D > d, L > d, so that when the supporting member 340 lifts the tray 500, the tray 500 will not interfere with the outfeed conveyor 310; at the same time, there is enough space between the infeed end of the infeed conveyor 320 and the outfeed end of the outfeed conveyor 310 in the conveying direction, which facilitates the operator to place a stack of trays 500 to the infeed conveyor 320.

[0053] In some embodiments, as shown in Figure 1 As shown, the outfeed conveyor 310 is arranged with at least one first lifting mechanism 370 for lifting the tray 500 away from the outfeed conveyor 310 along the conveying direction of the outfeed conveyor 310. Thus, when the empty tray 500 is taken out, the empty tray 500 is lifted by the first lifting mechanism 370, avoiding the operator from contacting the outfeed conveyor 310 and causing danger.

[0054] In some embodiments, as shown in Figure 1 As shown, the infeed conveyor 320 is arranged with at least one second lifting mechanism 380 for lifting the tray 500 away from the infeed conveyor 320 along the conveying direction of the infeed conveyor 320. Thus, when the supporting member 340 lifts the tray 500 at the outfeed end of the infeed conveyor 320, the tray 500 is lifted by the second lifting mechanism 380, avoiding the tray 500 from being sent into the outfeed end of the infeed conveyor 320 after the supporting member 340.

[0055] In some embodiments, as shown in Figure 1 As shown, one of the second lifting mechanisms 380 is located at the infeed end of the infeed conveyor 320. The second lifting mechanism 380 located at the infeed end of the infeed conveyor 320 is lifted first, so that the operator does not need to bend down or reduce the bending amplitude when placing the tray 500, thereby reducing the labor intensity of the operator.

[0056] In some embodiments, as shown in Figure 1 As shown, the outfeed conveyor 310 is provided with a tray stacking assembly 390 for stacking a plurality of trays 500 into a stack; as shown in Figure 1 and 9 As shown, the tray stacking assembly 390 includes a stopping mechanism 391 for stopping the tray 500, a third lifting mechanism 392 for lifting the tray 500 away from the outfeed conveyor 310, and a tray stacking mechanism 393 arranged on both sides of the third lifting mechanism 392; as shown in Figure 9As shown, the stacking mechanism 393 includes a second telescopic plate 3931 arranged telescopically along the conveying direction of the vertical outfeed conveyor 310 and a lifting mechanism 3932 driving the second telescopic plate 3931 to lift. It can be understood that the first baffle 321 can be provided with an avoiding hole or an avoiding slot to avoid the movement of the second telescopic plate 3931. By arranging the stacking assembly 390 to drop the empty trays 500 into a stack and then send out, the number of times of taking the empty trays 500 is greatly reduced. As shown in FIG. 6, the stacking assembly 390 is arranged on the outfeed conveyor 310. Figure 9 As shown, the second telescopic plate 3931 is telescopically arranged by a third telescopic cylinder 3933. Specifically, the cylinder body of the third telescopic cylinder 3933 is fixed to the output end of the lifting mechanism 3932, and the piston rod of the third telescopic cylinder 3933 is connected to the second telescopic plate 3931. As shown in FIG. 6, the third telescopic cylinder 3933 is arranged on the lifting mechanism 3932. Figure 9 As shown, the lifting mechanism 3932 is a fourth telescopic cylinder 3934, the cylinder body of the fourth telescopic cylinder 3934 is fixed to the side of the outfeed conveyor 310, and the piston rod of the fourth telescopic cylinder 3934 is connected to the cylinder body of the third telescopic cylinder 3933. The stopping mechanism 391 can be a check assembly or a blocking cylinder. In some embodiments, as shown in FIG. 6, the stopping mechanism 391 is arranged on the outfeed conveyor 310. Figure 9As shown, the stop mechanism 391 is a sixth telescopic cylinder 3911, and the cylinder body of the sixth telescopic cylinder 3911 is fixed to the discharge conveying belt 310. Initially, the piston rods of the fourth telescopic cylinder 3934 and the sixth telescopic cylinder 3911 are in the extended state, and the empty tray 500 moves on the discharge conveying belt 310, and then is stopped by the piston rod of the sixth telescopic cylinder 3911. The third lifting mechanism 392 lifts the stopped empty tray 500, and then the piston rod of the third telescopic cylinder 3933 is extended, so that the second telescopic plate 3931 extends below the skirt 510 of the empty tray 500. Then, the third lifting mechanism 392 is reset, the next empty tray 500 is stopped by the piston rod of the sixth telescopic cylinder 3911, the piston rod of the third telescopic cylinder 3933 is retracted, and the first empty tray 500 falls and is combined with the second empty tray 500. The third lifting mechanism 392 lifts the empty tray 500 again, and then the piston rod of the third telescopic cylinder 3933 is extended, so that the second telescopic plate 3931 extends below the skirt 510 of the empty tray 500. Then, the third lifting mechanism 392 is reset, and the cycle is repeated to stack N empty trays 500, N being a natural number. Then, when the N+1th empty tray 500 is stopped by the piston rod of the sixth telescopic cylinder 3911, the piston rod of the third telescopic cylinder 3933 is retracted, and the N empty trays 500 fall and are combined with the N+1th empty tray 500. Finally, the piston rod of the sixth telescopic cylinder 3911 is retracted to send the stack of trays 500 out. It can be understood that the empty tray 500 can be directly pushed to the tray stacking position by the tray pushing mechanism 350 to quickly stack the empty trays 500 and improve the efficiency. When the empty tray 500 is located at the tray stacking position, the fourth distance S between the pushing lever 3511 of the tray pushing mechanism 350 and the piston rod of the sixth telescopic cylinder 3911 is slightly larger than the size d of the empty tray 500 in the conveying direction, so as to avoid the pushing lever 3511 and the piston rod of the sixth telescopic cylinder 3911 pressing the empty tray 500 to cause the deformation of the empty tray 500, and at the same time, to ensure that the empty tray 500 falling from the second telescopic plate 3931 can be sleeved on the empty tray 500 of the third lifting mechanism 392.

[0057] In some embodiments, as Figure 9 As shown, the first lifting mechanism 370, the second lifting mechanism 380 and the third lifting mechanism 392 each include a lifting plate 372 and a fifth telescopic cylinder 371 driving the lifting plate 372. The cylinder body of the fifth telescopic cylinder 371 of the first lifting mechanism 370 and the third lifting mechanism 392 is fixed to the discharge conveying belt 310, and the lifting plate 372 of the first lifting mechanism 370 and the third lifting mechanism 392 is fixed to the piston rod of the corresponding fifth telescopic cylinder 371. The cylinder body of the fifth telescopic cylinder 371 of the second lifting mechanism 380 is fixed to the feeding conveying belt 320. The lifting plate 372 of the third lifting mechanism 392 is fixed to the piston rod of the corresponding fifth telescopic cylinder 371.

[0058] In some embodiments, the third telescopic cylinder 3933, the fourth telescopic cylinder 3934, and the fifth telescopic cylinder 371 are all guide rod cylinders.
