Description

Common automated feeding equipment includes roller feeders, pneumatic feeders, etc. The roller feeder transports the board by the rotation of the rollers, and can achieve continuous and stable feeding, which is suitable for boards with regular shapes. The pneumatic feeder uses the power of compressed air to push the board, and has the advantages of fast feeding speed and accurate positioning. The automated feeding equipment can be linked with the processing equipment to improve production efficiency and processing accuracy, and reduce the errors caused by manual operation. During feeding, since the backplane product needs to be transported to different workstations for processing, such as pasting adhesive strips, assembling accessories, etc., the backplane product needs to be flipped according to the processing requirements.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figures 1-7 , in the embodiment of the present invention, a feeding mechanism for a flip-back panel product includes a mounting frame 1 and a feeding frame 2 for placing the back panel product; it also includes

[0042] a suction cup mechanism 3 for adsorbing the back panel product;

[0043] A fixing bracket 4 is arranged on one side of the mounting bracket 1, and the fixing bracket 4 is placed on the top of the feeding bracket 2;

The suction cup mechanism 3 is arranged on one side where the bottoms of the two sets of housings 51 are close to each other, and the synchronous belt transmission member 55 is used to drive the suction cup mechanism 3 to flip;

[0046] A lifting mechanism 7 is installed on one side of the mounting bracket 1, which is used to drive the fixing bracket 4 to lift and adjust;

[0047] With the above scheme, the backplane product is sent to the top of the feeding bracket 2. The lifting mechanism 7 controls the fixing bracket 4 to lower, so that the suction cup mechanism 3 is placed at the bottom of the backplane product. Then the moving mechanism 6 works to adjust the two sets of moving seats 52 to be closer to each other, so that the suction cup mechanism 3 is aligned with the adsorption position at the bottom of the backplane product. Then the lifting mechanism 7 works to adjust the fixing bracket 4 to rise, driving the suction cup mechanism 3 to approach the backplane product and adsorb the backplane product. Then the driving member 54 works to drive the synchronous belt transmission member 55 to work, driving the suction cup mechanism 3 to flip. The backplane product flips 180°, places the backplane product on the feeding bracket 2, releases the adsorption and fixation of the suction cup mechanism 3 on the backplane product. Then the moving mechanism 6 controls the two sets of moving seats 52 to be farther away from each other, and the picked-up material of the flipped backplane product can be carried out.

[0048] Please refer to Figure 3 and Figure 6 , the suction cup mechanism 3 includes a fixed shaft 31 and a flipping frame 32 connected to one end of the fixed shaft 31.

The distance between the vacuum suction cups 34 is dynamically adjustable, which is compatible with backplane products in different width ranges.

[0050] Please refer to Figure 3The synchronous belt transmission member 55 comprises a flip wheel 552 and a transmission wheel 553 rotatably mounted in the housing 51, the flip wheel 552 and the transmission wheel 553 are connected by the synchronous belt 551, the transmission wheel 553 is provided with a spline shaft hole that slides with the spline shaft 53, and the center of the flip wheel 552 is provided with a mounting through hole for mounting the fixed shaft 31; the top of the housing 51 is provided with a first circular hole for the spline shaft 53 to pass through, the inner diameter of the first circular hole is larger than the outer diameter of the spline shaft 53, and the bottom of the housing 51 is provided with a second circular hole for the fixed shaft 31 to pass through;

[0051] Specifically, when the spline shaft 53 rotates, the transmission wheel 553 can be driven to rotate, achieving a flip angle error of less than 0.5°. After the transmission wheel 553 moves horizontally to adjust the position, the transmission wheel 553 can still be driven to rotate stably, allowing axial sliding to compensate for the displacement of the moving seat 52.

[0055] Specifically, the second motor 61 works and can drive the second dual-axis reversing reducer 62 to work. The second dual-axis reversing reducer 62 synchronously drives the two sets of lead screws 63 to rotate. In actual settings, if the power output shafts on both sides of the second dual-axis reversing reducer 62 have the same direction of rotation, the threads on the two sets of lead screws 63 can be set to have opposite directions of rotation, so as to control the relative movement of the two sets of moving seats 52.

Furthermore, a shield 64 is installed on the top of the fixed frame 4, and the shield 64 is placed on both sides of the second dual-axis reversing reducer 62 to protect the components on the top of the fixed frame 4.

During the rotation of the belt 73, the lifting seat 41 can be driven to perform stable lifting adjustment on one side of the lifting frame 71.

[0058] The working principle of the present invention is as follows: The backplane product is sent to the top of the feeding frame 2 through an external conveying system. The lifting mechanism 7 controls the fixing frame 4 to descend, so that the suction cup mechanism 3 approaches the bottom of the backplane product, leaving a safety distance;

[0059] The moving mechanism 6 works to adjust the two moving seats 52 to approach each other, adjust the spacing of the suction cup mechanism 3, adapt to different widths of the backplane, and align the suction cup mechanism 3 with the bottom adsorption position of the backplane product;

[0060] The lifting mechanism 7 works to adjust the fixing frame 4 to slightly rise, drive the suction cup mechanism 3 to approach the backplane product and adsorb the backplane product.
