[0036] Reference Figure 1-2The first linear slide rail 11 is arranged along the length direction of the truss 1, and the horizontal driving mechanism 12 includes a second motor 121 installed on the truss 1 and a transmission belt 122 connected to the second motor 121 by a pulley connection. A connection block 123 is fixed to the lower side of the transmission belt 122. The transmission direction of the lower side of the transmission belt 122 is the same as the length direction of the truss 1. The connection block 123 is fixedly connected to the moving seat 2. When the second motor 121 is started, it drives the transmission belt 122 to move, and the movement of the transmission belt 122 drives the connection block 123 to move, and the movement of the connection block 123 drives the moving seat 2 to move, thereby achieving the purpose of driving the moving seat 2 to move along the length direction of the truss 1.

[0037] Reference Figure 2-3 The second linear slide rail 21 is arranged along the vertical direction, and the vertical driving mechanism 22 includes a driving shaft 221 and a driving gear 222. The driving shaft 221 is rotatably connected to the moving seat 2, and a first motor 223 is installed on the moving seat 2. The driving shaft 221 and the first motor 223 are transmission-connected, and the driving gear 222 is coaxially fixed to both ends of the driving shaft 221. A driving rack 224 corresponding to the driving gear 222 is fixed on the suction cup frame 3, and each driving rack 224 is vertically arranged and meshes with the corresponding driving gear 222. When the first motor 223 rotates, it drives the driving shaft 221 to rotate, and the driving shaft 221 rotates to drive the driving gear 222 to rotate, and the driving gear 222 rotates to drive the driving rack 224 to move upward or downward, thereby achieving the purpose of driving the suction cup frame 3 to move up and down.

[0038] Reference Figure 1-2 An oil supply tank 23 is installed on the side wall of the movable seat 2. The output end of the oil supply tank 23 can be connected to a pipeline to add anti-rust oil or lubricating oil to the first linear slide rail 11, which is conducive to smooth sliding and ensures the service life of the first linear slide rail 11.

[0039] Reference Figure 2 , a self-weight eliminating cylinder 24 is installed on the side wall of the movable seat 2, and the piston rod of the self-weight eliminating cylinder 24 is connected to the suction cup frame 3. The suction cup frame 3 is provided with an air storage part 31, and the self-weight eliminating cylinder 24 is connected to the air storage part 31. In this embodiment, the air storage part 31 is an air storage container with an air cavity inside. In this way, the air storage part 31 serves as an air source for the self-weight eliminating cylinder 24 and can continuously supply air to the self-weight eliminating cylinder 24. When the vertical driving mechanism 22 drives the suction cup frame 3 to move up and down, the air storage part 31 is used to supply air to the self-weight eliminating cylinder 24, so that the self-weight eliminating cylinder 24 can generate a pulling force in the opposite direction of the gravity of the suction cup frame 3, thereby offsetting all or part of the self-weight of the suction cup frame 3, thereby reducing the load and energy consumption of the vertical driving mechanism 22, and helping to extend the service life of the vertical driving mechanism 22. In addition, it is helpful to avoid or reduce the inertial force generated by the self-weight of the suction cup frame 3, thereby improving the stability of the blank board material transportation.

[0040] Reference Figure 2The self-weight eliminating cylinder 24 is vertically arranged and the piston rod of the self-weight eliminating cylinder 24 is arranged upward, a connecting piece 241 is fixed to the top of the piston rod of the self-weight eliminating cylinder 24, a connecting side plate 32 is fixed to the suction cup frame 3, and the connecting piece 241 is rotatably connected to the connecting side plate 32 through a pin 321. In this embodiment, the connecting piece 241 is a U-shaped block. In this way, the above arrangement can make the installation requirements of the self-weight eliminating cylinder 24 less high, improve the tolerance of the installation, be more flexible, and prevent the occurrence of the jamming phenomenon.

[0041] Reference Figure 2 The air storage part 31 is provided with an air inlet nozzle 311 and an air outlet nozzle 312, and the air outlet nozzle 312 is connected to the air inlet of the self-weight elimination cylinder 24 to facilitate the supply of air to the self-weight elimination cylinder 24. A pressure detector 33 is installed on the suction cup frame 3, and the detection end of the pressure detector 33 is connected to the inner cavity of the air storage part 31. In this embodiment, the pressure detector 33 is an air pressure sensor, which can perform online detection of the air pressure in the air storage part 31. When the pressure value in the air storage part 31 is lower than the set value, it means that the air storage part 31 needs to be filled with air, and air can be added to the air storage part 31 through the air inlet nozzle 311 to ensure that the air storage part 31 can continuously supply air to the self-weight elimination cylinder 24. Furthermore, the pressure detector 33 can be connected to the external alarm signal. When the pressure value detected by the pressure detector 33 is too low, the external alarm will sound to prompt the staff to perform the air filling operation.

Through the arrangement of the vacuum generator 34, a stable vacuum can be quickly generated, so that the vacuum suction cup 41 generates a certain vacuum degree. Compared with the traditional vacuum pump that can generate a vacuum, it is smaller in size and weight, which is conducive to further reducing the load and energy consumption of the vertical drive mechanism 22.

[0044] In a specific application scenario, after the raw board is adsorbed in the air, the electric telescopic rod 503 is retracted and adjusted, so that the movable plate 504 drives the active rack 505 to move to the side of the electric telescopic rod 503, and the active rack 505 is meshed with the driven gear 506, so that the driven gear 506 rotates accordingly and drives the positioning rotating plate 508 to rotate through the connecting rod 507, and the eccentric rotating rod 509 changes position accordingly, and the vertical guide rail 511 slides upward along the surface of the slide seat 1 512, so that the guide plate 510 moves upward accordingly, and at the same time, the slide seat 2 513 slides along the surface of the horizontal guide rail 514, driving the buffer table 519 to move to the bottom of the raw board, so as to realize the anti-fall protection of the raw board. After the raw board is transferred to the top of the feeding point, the electric telescopic rod 503 is stretched and adjusted to move the buffer table 519 to the side and bottom of the raw board, and feeding can be carried out at this time, and the structure is simple.

The surface of the guide rod 523 is sleeved with two springs 527, and the ends of the two springs 527 that are away from each other are fixedly connected to the outer walls of the two sliding sleeves 524 on one side close to each other.

[0046] In a specific application scenario, when the blank board falls due to external factors during the loading process, the blank board falls on the buffer pad 521, and the buffer pad 521 is used to form a preliminary buffer for the blank board. At the same time, the blank board exerts pressure on the buffer table 519, causing the buffer table 519 to slide along the surface of the guide column 518 and exert pressure on the spring 1 520, and a secondary buffer is formed by the elastic action of the spring 1 520.
