Description

Technical Field

[0001] The utility model belongs to the technical field of material handling, and particularly relates to a variable-spacing lifting and handling mechanism.

Background Art

[0002] In automated equipment in fields such as semiconductors, photovoltaics, and 3C, suction nozzles are commonly used to suck products for processes such as transplanting and handling based on the principle of vacuum adsorption. To improve efficiency, multiple groups of suction nozzles are often used simultaneously at one station for product handling. Under normal circumstances, the distance between multiple groups of suction nozzles is set according to the arrangement distance between the products to be sucked. However, in some cases, the distance between the arrangement distances of the products and the positions where the suction nozzles are required to be placed after handling is different. The traditional operation method is to manually adjust the cooperation of screws and nuts to increase or decrease the distance between the suction nozzles. However, this adjustment method is time-consuming and laborious for loading and unloading, greatly reducing the efficiency of handling or transplanting, and is very inconvenient.

[0003] Therefore, in the prior art, relevant automated variable-spacing handling modules are designed to automatically adjust the distance between multiple suction nozzles to meet the arrangement spacing between products. For example, a variable-spacing feeding device disclosed in Chinese Patent Grant Publication No. CN219097758U, a variable-spacing mechanism, the variable-spacing mechanism is installed on a guide rail, the variable-spacing mechanism includes a mounting plate, a lifting motor is installed on the mounting plate, and several picking mechanisms are arranged on one side of the variable-spacing mechanism. When the lifting motor is started, the variable-spacing mechanism is used to make the picking mechanisms have different distances; although this solution can achieve the functions of variable spacing and lifting, in this solution, a variable-spacing plate is provided between the picking mechanism and the mounting plate, and several guide grooves with different slopes are provided on the variable-spacing plate. The variable-spacing function is realized by driving the variable-spacing plate to lift by a lifting motor and simultaneously making multiple picking mechanisms move along the guide grooves with different slopes. Therefore, in this solution, lifting and variable spacing are achieved simultaneously, and the variable-spacing function can only be applied to specific usage scenarios, with low versatility.

[0004] A multi-station variable pitch lifting and rotating module disclosed in the Chinese patent authorization announcement number CN218024151U, a lifting and rotating assembly, which is installed on the moving plate of the translation assembly. The lifting and rotating assembly includes a connecting seat, a limiting chute is opened on the connecting seat, a limiting slider is installed in the limiting chute, and a cylinder for driving the limiting slider to lift and slide is installed on the connecting seat; a second motor is fixedly installed on one side of the connecting seat through a motor seat. The translation assembly includes a bottom plate and a camshaft, and the first motor is in transmission connection with the camshaft of the translation assembly through a transmission box; in this solution, the first motor drives the camshaft to drive the horizontal movement of the lifting and rotating assembly to adjust the distance between the lifting and rotating assemblies, and the lifting and rotating assembly realizes the lifting function through the cylinder. In the above solution, the variable pitch and lifting functions are realized independently, which is suitable for the transfer of workpieces of different sizes. However, in this solution, the lifting function of the lifting and rotating assembly is realized by the cylinder, and multiple cylinders need to be designed to realize the lifting function for multiple lifting and rotating assemblies. This not only makes the structural design complex, but also the applicable stroke range of the cylinder is limited, which is not conducive to automated production during lifting.

[0005] Therefore, it is necessary to provide a variable pitch lifting and handling mechanism to solve the above technical problems.

Detailed Embodiment

[0023] Please refer to Figures 1 - 3, this embodiment is a variable pitch lifting and handling mechanism. The variable pitch lifting and handling mechanism 72 includes a handling frame 721, a lifting drive module 722 arranged on the handling frame 721, a pushing frame 723 driven by the lifting drive module 722 to perform lifting movement, and a plurality of adsorption components 724 driven by the pushing of the pushing frame 723 to move downward simultaneously. The adsorption components 724 are movably arranged on an adjusting plate 725. An elastic component 7211 for resetting the adsorption component 724 upward is arranged between the adsorption component 724 and the adjusting plate 725. A plurality of adjusting plates 725 are arranged in the horizontal direction, and an adjusting module 7210 for adjusting the horizontal spacing of the adjusting plates 725 is arranged on the handling frame 721.

[0024] In this embodiment, since the number of adsorption components 724 is eight, and every two adsorption components 724 before and after are in a group and movably arranged on the adjusting plate 725, a total of four adjusting plates 725 are arranged. In other embodiments, the number of adsorption components 724, the number of adjusting plates 725, and the number of adsorption components 724 installed on each adjusting plate 725 can be adjusted according to actual situations, and are not limited herein.

[0025] The adjusting module 7210 includes a rotary drive member 727 arranged on the handling frame 721 and an adjusting shaft 728 driven by the rotary drive member 727 to rotate. A spiral groove 7281 is arranged on the outer wall of the adjusting shaft 728. Avoidance grooves 7251 for the adjusting shaft 728 to pass through are arranged on a plurality of adjusting plates 725. A pin shaft 729 extending into the spiral groove 7281 of the adjusting shaft 728 is arranged on the upper groove wall of the avoidance groove 7251. When the rotary drive member 727 drives the adjusting shaft 728 to rotate, the pin shaft 729 moves in the spiral groove 7281 of the screw 7172 to drive the adjusting plate 725 to move in the horizontal direction. Moving the adjusting plate 72 drives the adsorption component 724 to move in the horizontal direction, thereby realizing the adjustment of the horizontal spacing of a plurality of adsorption components 724. In order to improve the stability of the adjusting plate 725 moving in the horizontal direction, the adjusting plates 725 are all horizontally movably arranged on a plurality of guide shafts 726. The two ends of the guide shafts 726 are fixed on the handling frame 721. In this embodiment, the four adjusting plates 725 are movably installed on the handling frame 721 through six guide shafts 726.

[0026] The adsorption assembly 724 includes a mounting block 7241 at the upper end and an adsorption rod 7242 provided at the lower end of the mounting block. The adsorption rod 7242 is mounted on the adjustment plate 725 through a bearing. The mounting block 7241 and the adjustment plate 725 are connected together through an elastic component 7211. The elastic component 7211 includes a spring pull rod fixed to the upper end of the adjustment plate 725 and a spring with its upper end arranged on the spring pull rod and its lower end fixed to the mounting block 7241. When the push frame 723 pushes the adsorption assembly 724 downward, the spring is stretched. When the push frame 723 moves upward, the spring contracts to drive the adsorption assembly 724 to rise and reset. In order to improve the stability of the up and down movement of the adsorption rod 7242, a number of vertical guide rods 7244 are installed between the mounting block 7241 and the adjustment plate 725. Two adsorption assemblies 724 are installed front and back on an adjustment plate 725. Support shafts 7246 for the push frame 723 to push are provided on the relatively inner sides at the upper ends of the two adsorption assemblies 724.

[0027] The adsorption rod 7242 includes an adsorption head 7243 provided at the lower end for adsorbing the chip and an adsorption channel penetrating the upper and lower ends. An air inlet 7245 communicated with the adsorption channel is provided on the side wall of the mounting block 7241. The air inlet 7245 and the adsorption channel are communicated to form a gas inlet and outlet channel for gas to enter and exit. When adsorbing and transporting the workpiece, the gas inlet and outlet channel is connected to a vacuum pump to evacuate the air, so as to realize the vacuum adsorption of the workpiece by the adsorption head 7243.

[0028] The lifting drive module 722 includes a lifting drive member 7221 fixed to the handling frame 721 and a transmission component driven by the lifting drive member 7221 to rotate synchronously. The transmission component includes a first transmission shaft fixed to the output shaft end of the lifting drive member 7221, a second transmission shaft arranged at the same height as the first transmission shaft and rotatably arranged on the other opposite side of the handling frame 721, and a third transmission shaft 7222 located above the first transmission shaft and the second transmission shaft.

[0029] First synchronous wheels 7223 are fixed on both the first transmission shaft and the third transmission shaft 7222. The two first synchronous wheels 7223 are connected together by a first synchronous belt 7224 to achieve rotational transmission; second synchronous wheels 7225 are fixed on both the second transmission shaft and the third transmission shaft 7222. The two second synchronous wheels 7225 are connected together by a second synchronous belt 7226 to achieve rotational transmission.

[0030] Belt clips 7227 are fixed on both the first synchronous belt 7224 and the second synchronous belt 7226. The push frame 723 is arranged on the lifting drive module 722 through the belt clips 7227. In order to improve the stability of the lifting of the push frame 723, a slide rail 7211 is provided on the handling frame 721. The push frame 723 is slidably arranged on the slide block 7231 through a slide block. A sensor 7212 for detecting the material is also provided on the handling frame 721.

[0031] When applying a variable-pitch lifting and handling mechanism 72 provided by this solution, the lifting drive member 7221 drives the first transmission shaft to rotate, thereby driving the push frame 723 to move downward to push the suction rods 7242 of a plurality of suction components 724 to move downward simultaneously. The gas inlet and outlet channels are connected through a vacuum pump to evacuate the air, so as to realize the vacuum suction of the workpiece by the suction head 7243. After the suction is completed, when the push frame 723 moves upward, the spring contracts to drive the suction component 724 to rise and reset, thereby driving the adsorbed workpiece to move upward. If it is necessary to change the distance between a plurality of suction components 724, the rotation drive member 727 drives the adjustment shaft 728 to rotate. When the pin shaft 729 moves in the spiral groove 7281 of the screw rod 7172, it drives the adjustment plate 725 to move horizontally. Moving the adjustment plate 725 drives the suction component 724 to move horizontally, so as to realize the adjustment of the distance between a plurality of suction components 724 in the horizontal direction; in this solution, the lifting movement and the variable-pitch movement are independent of each other, and it can be applied to workpieces of different sizes or workpieces arranged at different intervals, with higher versatility; moreover, a lifting drive module 722 can simultaneously realize the lifting movement between a plurality of suction components 724, making the layout of the entire mechanism compact, occupying less space, and having higher handling efficiency.

[0032] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the creative concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
