[0002] With the progress of society and the development of science and technology, it has become a mainstream trend for automated equipment to replace manual work. This is also true for the automotive industry. Robots can be seen in the four major processes, including stamping, welding, painting, and assembly, and their automation level is getting higher and higher. The end picker on the manipulator is the hands of the stamping and handling robot and is the most commonly used equipment in robot operations.

[0003] Due to the different product contours, the end picker needs to adjust the spacing or increase the number of installations to ensure accurate adsorption of the metal workpiece. The adsorption unit on the existing end picker cannot adjust its spacing. When adsorbing metal workpieces with different contours, the metal workpiece often cannot be adsorbed or cannot be accurately adsorbed. Sometimes, the metal workpiece needs to be manually adjusted to enable the end picker to accurately adsorb the metal workpiece. The operation is complicated and inconvenient to use. The working error is large, the work efficiency is slow, and the economic benefits are affected. In addition, the workpiece may be scratched by the metal workpiece when it is manually adjusted.

[0007] Further optionally, one end of the lead screw extends to the outside of the slide rail and is connected and fixed with a handwheel for rotating the lead screw.

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementations:

[0020] like Figure 1 As shown, an end picker for a stamping production line includes a manipulator 1, and two connecting arms 3 connected and fixed by a connecting plate 2 are provided at the wrist end of the manipulator 1. The characteristic is that an adjusting component is connected and fixed at the end of the connecting arm 3, and the adjusting component includes a slide rail 4, and two sliders 12 are slidably connected in the slide rail 4, and the corresponding sliders 12 are threadedly connected to the lead screw 10 rotatably supported inside the slide rail 4, and a stabilizing component is connected and fixed to the lower part of the slider 12, and the stabilizing component is slidably connected to multiple support rods 7, and a number of adsorption units are connected and fixed to the corresponding support rods 7.

[0021] like Figure 1 , 2 As shown in , 3 , one end of the lead screw 10 extends to the outside of the slide rail 4 and is connected and fixed with a hand wheel 14 for rotating the lead screw 10 .

[0022] like Figure 4 As shown, the screw 10 is divided into a right-hand thread 16 and a left-hand thread 17 at the middle.

[0023] like Figure 1 As shown, the adsorption unit includes a plurality of suction cups 9 for adsorbing workpieces, and the suction cups 9 are connected and fixed to the support rod 7 through a clamping block 8.

[0024] like Figure 1 , 2 As shown, the stabilizing component includes a scissor-type cross bracket 6 hingedly connected between the sliders 12 and a V-shaped bracket 5 fixedly connected to the outer side of the corresponding slider 12. When the manipulator presses down to adsorb the workpiece, the stabilizing component can increase the strength of the end picker to prevent the workpiece from deformation during adsorption.

[0025] like Figure 1 As shown, two adjusting blocks 13 are slidably connected to the corresponding V-shaped bracket 5. The adjusting blocks 13 are provided with through holes for placing the support rods 7. One side of the adjusting blocks 13 is provided with a top screw 15 to prevent the support rods 7 from sliding.

[0026] like Figure 1 , 2 As shown, two support blocks 11 for placing corresponding support rods 7 are connected and fixed in the middle of the scissor-type cross bracket 6 .

[0027] The implementation principle of an end picker for a stamping production line in the embodiment of the present application is as follows:

[0028] Before performing the adsorption operation, the corresponding adjustment block 13 is first placed on the V-shaped bracket 5 and adjusted to the corresponding position (adjusted according to the on-site conditions). After the adjustment, the support rod 7 is inserted into the corresponding adjustment block 13 and the connecting block 11, and the support rod 7 is fixed with the corresponding top screw 15. The suction cup 9 is fixed on the support rod 7 through the clamping block (8), and the adsorption operation is prepared;

[0029] During the adsorption operation, the manipulator 1 is started to move all the suction cups 9 to the upper part of the workpiece, and the manipulator 1 starts to press down for adsorption at the same time, and the external air supply starts at the same time, and the suction cups generate suction to adsorb the workpiece;

[0030] When adsorbing a workpiece with a larger area, the spacing of the adsorption units needs to be expanded, the top screw 15 on the connecting block 11 is loosened, and the hand wheel 14 is turned forward. During the rotation of the hand wheel 14, the lead screw 10 will rotate synchronously, and the slider 12 installed on the right-hand lead screw 16 and the left-hand lead screw 17 will slide to both sides of the slide rail 4. At the same time, the spacing between the V-shaped brackets 5 on both sides becomes larger, thereby increasing the adsorption area;

[0031] When the suction cups 9 on the suction units on both sides exceed the workpiece, the spacing between the suction units needs to be reduced. To reduce the spacing between the suction units, the hand wheel 14 needs to be rotated in the opposite direction according to the above steps, which will make the slider 12 move closer to the middle, making the spacing between the suction units smaller, so that all the suction cups 9 are on the upper part of the workpiece, so that the workpiece can be adsorbed;

[0032] If an adsorption unit needs to be added, the top screw 15 of the adjustment block 13 on the V-shaped bracket 5 is loosened, and the adjustment block 13 is pushed inward along the V-shaped bracket 5. The adjustment block 13 with the same structure is installed on the V-shaped bracket 5, and then the same adsorption unit is installed on the adjustment block 13, so that the adsorption unit can be added;

[0033] The entire adjustment process saves time and effort, which can protect personnel safety and achieve the adsorption of metal workpieces with different shapes and contours.

[0034] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
