[0002] When producing sheet metal, it is usually necessary to use a robot at the end of the conveyor line to move the sheet metal out of the conveyor line and stack the sheet metal at other locations.

[0003] In the prior art, a small section of a separate sheet material centering conveyor line is set at the end of the conveyor line. The sheet material centering conveyor line is used to center the sheets to facilitate the neat stacking of subsequent sheets. The above-mentioned sheet material centering conveyor line generally includes side centering components located on both sides of the conveyor line and front centering components located on the front side of the conveyor line to center the sheets.

[0004] Since factories generally do not produce only sheets of a single size, the sheet centering conveyor line needs to have a certain amount of adjustment space. In the prior art, the side centering component can move left and right, and the front centering component can move front and back to adapt to sheets of different sizes. However, the side centering component generally adopts a solution in which multiple cylindrical structures are arranged in the front-to-back direction. The position of the front centering component will be limited by the cylindrical structure, resulting in poor adaptability of the front centering component to different sheets, resulting in the final sheet being unable to be centered front and back. When the robot arm grabs, it will deviate from the center of the sheet in the front-to-back direction, resulting in uneven force on both sides of the robot arm. Long-term work will cause damage to the robot arm, which is not conducive to ensuring the service life of the robot arm. Summary of the invention

[0024] Reference Figure 1 to Figure 2 The sheet centering conveying line includes a frame 100, a conveying assembly 200, a front centering assembly 300, a side centering assembly 400, and a side avoidance assembly 500.

[0025] The conveying assembly 200 is provided with a conveying plane. The conveying assembly 200 includes a conveying drive motor 210 and a plurality of conveying units 220. The conveying drive motor 210 is fixedly mounted on the frame 100, and the conveying units 220 are rotatably mounted on the frame 100. The plurality of conveying units 220 are arranged in the front-to-back direction, and the driving structure of the conveying assembly 200 is the same as the driving structure of a conventional roller conveyor, and the conveying drive motor 210 drives the plurality of conveying units 220 to move synchronously through chains and sprockets.

[0026] In this embodiment, the conveying unit 220 includes a plurality of main conveying rollers 221 and a plurality of connecting conveying rollers 222 , and the plurality of main conveying rollers 221 and the plurality of connecting conveying rollers 222 are arranged along the left-right direction.

[0027] The connecting conveying roller 222 is disposed on two adjacent main conveying rollers 221, and the two ends of the connecting conveying roller 222 are respectively fixedly connected to the two main conveying rollers 221. The diameter of the connecting conveying roller 222 is smaller than the diameter of the main conveying roller 221, and the conveying plane is tangent to the upper ends of the main conveying rollers 221 of the plurality of conveying units 220, so that the conveying units 220 are formed with a plurality of notches arranged along the left and right sides. The plurality of notches of the plurality of conveying units 220 are combined to form a plurality of first channels.

[0028] The front centering assembly 300 is disposed at the rear of the frame 100 , and the front centering assembly 300 includes a front centering adjustment structure and a front centering plate 320 .

[0029] Specifically, the front centering adjustment structure includes two front centering drive units 310 , and the two front centering drive units 310 are symmetrically installed on the left and right sides of the frame 100 .

[0030] The front centering drive unit 310 includes a guide rod 311 , a guide slide 312 , a forward drive belt assembly 313 and a forward drive member 314 .

[0031] The guide rod 311 is fixedly mounted on the frame 100, and the guide rod 311 extends in the front-rear direction. Specifically, the guide rod 311 is a cylindrical polished rod structure.

[0032] The guide slide 312 is slidably connected to the guide rod 311 .

[0033] The forward drive belt assembly 313 includes a synchronous belt and two synchronous wheels. The two synchronous wheels are both rotatably connected to the frame 100. The synchronous belt passes around the two synchronous wheels, and the synchronous belt meshes with the synchronous wheels.

[0034] The forward driving member 314 is fixedly mounted on the frame 100 . The forward driving member 314 is configured as a servo motor. The output end of the forward driving member 314 is fixedly connected to a synchronous wheel at the rear to drive the synchronous wheel to rotate, thereby driving the synchronous belt to work.

[0035] Specifically, in this embodiment, the two front centering drive units 310 share the same forward drive member 314, and the forward drive belt assemblies 313 of the two front centering drive units 310 are connected via a connecting shaft 315, and the two ends of the connecting shaft 315 are respectively fixed to two synchronous wheels, thereby realizing the power transmission of the two front centering drive units 310. In other embodiments, the two front centering drive units 310 can also be configured to be each equipped with a forward drive member 314, but it is necessary to ensure that the driving speeds of the two forward drive members 314 are the same, and those skilled in the art can select the number of the forward drive members 314 according to actual needs.

[0036] The lower end of the front centering plate 320 is flush with the conveying plane. The left and right ends of the front centering plate 320 are respectively fixedly connected to the guide slides 312 of the two front centering drive units 310, so that when the guide slides 312 move forward and backward, the front centering plate 320 will move forward and backward with the guide slides 312.

[0037] Reference Figure 3 Specifically, a front limiting protrusion 321 is protruded from the lower end of the front centering plate 320, and the front limiting protrusion 321 is lower than the conveying plane. The number of the front limiting protrusions 321 is set to be multiple, and the multiple front limiting protrusions 321 are arranged in the left and right directions. The front limiting protrusions 321 are set in a one-to-one correspondence with the first channel, and the front limiting protrusions 321 slide in the first channel.

[0038] The number of the side centering assemblies 400 is set to two, and the two side centering assemblies 400 are symmetrically arranged on the left and right sides of the frame 100. Specifically, the side centering assembly 400 includes a side centering unit 410, a centering connection frame 420 and a side centering driving structure 430.

[0039] Specifically, in this embodiment, the two side centering assemblies 400 are driven by the same side centering driving structure 430 , and the side centering driving structure 430 drives the centering connecting frames 420 of the two side centering assemblies 400 to move closer to or away from each other.

[0040] Specifically, in the present embodiment, the side-centering drive structure 430 includes a side-centering drive member 431 and a side-centering drive belt assembly 432. The side-centering drive belt assembly 432 includes a synchronous belt and two synchronous wheels. The two synchronous wheels are both rotatably connected to the frame 100. The synchronous belt passes around the two synchronous wheels, and the synchronous belt is meshed with the synchronous wheels. The two synchronous wheels of the side-centering drive belt assembly 432 are arranged in the left-right direction. The two synchronous wheels are both rotatably connected to the frame 100. The synchronous belt passes around the two synchronous wheels, and the synchronous belt is transmission-connected to the synchronous wheels.

[0041] The two centering connecting frames 420 of the two side centering assemblies 400 are respectively fixedly connected to the upper and lower sections of the synchronous belt of the side centering drive belt assembly 432. Since the upper and lower sections move in opposite directions when the synchronous belt moves, the two centering connecting frames 420 are respectively fixedly connected to the upper and lower sections of the synchronous belt of the side centering drive belt assembly 432, so that the synchronous belt can drive the two centering connecting frames 420 to move closer to or away from each other in the left and right directions when moving.

[0042] The number of the side centering units 410 in each side centering assembly 400 is set to be multiple, and the multiple side centering units 410 are arranged at intervals along the front-to-back direction.

[0043] Specifically, the side centering unit 410 includes a centering column 411 and a seat 412. The lower end surface of the seat 412 abuts against the frame 100, and the seat 412 is slidably connected with the frame 100 in the left-right direction. A guide rail and a guide groove are provided between the seat 412 and the frame 100 to limit the sliding direction of the seat.

[0044] The centering column 411 is installed above the base 412, and the multiple centering columns 411 of the two side centering assemblies 400 cooperate to perform the centering step of the plate in the left-right direction.

[0045] Specifically, in this embodiment, the centering column 411 is set as a cylindrical structure. During the side centering process, the outer peripheral surface of the centering column 411 will contact the side wall of the sheet material, thereby limiting the position of the sheet material in the left and right directions; at the same time, the sheet material will continue to be transported forward, and setting the centering column 411 as a cylindrical structure can reduce the friction between the side centering unit 410 and the sheet material.

[0046] Specifically, in this embodiment, the centering column 411 is rotatably connected to the seat 412. The centering column 411 is configured to be rotatably connected to the seat 412, which can reduce the friction between the sheet material and the centering column 411 when relative displacement occurs in the front-to-back direction, thereby reducing the wear of the sheet material.

[0047] The side centering unit 410 is detachably connected to the centering connection frame 420 , and the side centering unit 410 can move along the left-right direction with the centering connection frame 420 .

[0048] Reference Figure 4 Specifically, the side avoidance assembly 500 includes: a control rod 510, a connecting rod 520, a locking rod 530, a locking groove 540, a control moving seat 550, and a control restoring member 560.

[0049] The control rod 510 extends in the up-down direction, and the control rod 510 is slidably connected to the seat body 412 . The upper and lower ends of the control rod 510 are respectively configured as a connecting end and a control end, and the control end is configured above the connecting end.

[0050] The manipulation reset member 560 is disposed between the seat body and the manipulation rod 510 . The manipulation reset member 560 is configured as a spring. The manipulation reset member 560 is used to drive the manipulation rod 510 to reset upward.

[0051] Specifically, in this embodiment, the control end is a hemispherical structure, so that other components can more easily drive the control end to move downward.

[0052] One end of the connecting rod 520 is hingedly connected to the connecting end, and the connecting rod 520 gradually tilts upward in a direction away from the connecting end. In other embodiments, the connecting rod 520 in a normal state can also be set to be horizontal, and those skilled in the art can select the tilt angle of the connecting rod 520 according to actual needs.

[0053] The locking rod 530 is horizontally arranged and extends in the front-to-back direction. The locking rod 530 and the seat body 412 extend in the front-to-back direction. The locking rod 530 is hingedly connected to an end of the connecting rod 520 away from the connecting end.

[0054] When the operating rod 510 moves downward, the inclination angle of the connecting rod 520 increases, so that the locking rod 530 is retracted into the seat body 412 . When the operating rod 510 moves upward, the locking rod 530 is extended out of the seat body 412 .

[0055] The locking groove 540 is formed on the centering connecting frame 420 , and the position of the locking groove 540 matches the position of the locking rod 530 .

[0056] Specifically, in this embodiment, the number of the connecting rod 520, the locking rod 530 and the locking slot 540 is respectively set to two. The two connecting rods 520, the two locking rods 530 and the two locking slots 540 are symmetrically arranged on the front and rear sides of the control rod 510.

[0057] When the front centering component 300 moves to one of the side centering units 410, the control movable seat 550 is moved to the top of the control rod 510, the lower end surface of the control movable seat 550 is abutted against the control end, and the control rod 510 deviates downward from the original position, so that the locking rod 530 is retracted into the seat body 412, the locking rod 530 is separated from the locking groove 540, and the side centering unit 410 is separated from the centering connecting frame 420. When the centering connecting frame 420 moves in the left and right directions, the side centering unit 410 does not move with the centering connecting frame 420 to avoid the side centering unit 410 from colliding with the front centering plate 320, thereby ensuring the normal operation of the sheet centering conveyor line.

[0058] The implementation process of this plan is: When it is necessary to adapt to sheets of different specifications, the side centering assembly 400 is first reset, and then the control system of the sheet centering conveyor line controls the forward driving member 314 to drive the front centering plate 320 to move to the specified position. After the front centering plate 320 moves to the specified position, if the front centering plate 320 moves between the two side centering units 410, there is a risk of interference between the two ends of the front centering plate 320 and the side centering units 410. At this time, the control moving seat 550 will automatically press the control rod 510 downward, thereby driving the locking rod 530 to be received into the seat body 412, and the locking rod 530 is separated from the locking groove 540, so that the two side centering units 410 on the left and right sides of the front centering plate 320 are separated from the centering connecting frame 420, and then the side centering driving structure 430 drives the two centering connecting frames 420 to approach each other, thereby driving multiple side centering units 410 that are not separated from the centering connecting frame 420 to move to adapt to sheets of different specifications. At this time, the two side centering units 410 separated from the centering connecting frame 420 remain stationary (i.e., the two side centering units 410 on the left and right sides of the front centering plate 320) to avoid the two front centering plates 320 on the left and right sides of the front centering plate 320 from colliding with the side centering units 410, thereby ensuring the normal operation of the sheet metal centering conveyor line; and the position of the front centering plate 320 can be adjusted steplessly, which can better adapt to sheets of different specifications to ensure that sheets of different specifications can be centered in the front and rear directions, so that the force at each location is more balanced when the robot arm grasps, which can effectively extend the service life of the robot arm.
