[0037] Reference Figures 1 to 5 A jig conveying device 100 includes: a base 110; a translation conveying device, which is arranged on the base 110; a first stacking frame 140 and a second stacking frame 150, which are arranged on the base 110; a spacing adjustment device, which is used to adjust the distance between the first stacking frame 140 and the second stacking frame 150; the translation conveying device is used to transport the jigs stacked between the first stacking frame 140 and the second stacking frame 150 in the front-to-back direction.

[0038] The jig conveying device 100 of the present embodiment can, when in use, adjust the distance between the first stacking frame 140 and the second stacking frame 150 according to the sizes of different jigs through the spacing adjustment device. When feeding is required, the jigs stored between the first stacking frame 140 and the second stacking frame 150 are conveyed to the feeding position through the translation conveying device, thereby adapting to jigs of different sizes without replacing parts.

[0039] Among them, the spacing adjustment device can adjust the distance between the first stacking frame 140 and the second stacking frame 150 in different ways, for example, the first stacking frame 140 and the second stacking frame 150 are set on the slide rail and adjusted manually; the motor can also drive the lead screw and the lead screw nut 230 to drive the second stacking frame 150 to move relative to the first stacking frame 140; or the linear motor or cylinder and other devices can be used to drive the first stacking frame 140 to move relative to the second stacking frame 150, etc.

[0040] It can be understood that the translation conveying device can convey the jig stacked between the first stacking frame 140 and the second stacking frame 150 to the feeding position in a variety of ways, such as by grabbing the jig and transporting it to the feeding position through a gripper, or by a belt or transport roller or other device provided on the front side of the first stacking frame 140, and by a pushing device provided on the rear side of the first stacking frame 140 to push the jig onto the belt or transport roller and transport it to the feeding position; the translation conveying device can also be extended between the first stacking frame 140 and the second stacking frame 150, and the jig can be stacked above the translation conveying device.

[0041] like Figure 1 , Figure 4 As shown, the jig conveying device 100 is characterized in that it also includes: a first side plate 120, which is arranged on the base 110 and located on the left side of the translation conveying device, and a first stacking frame 140 is arranged at the upper end of the first side plate 120; a second side plate 130, which is arranged on the base 110 and located on the right side of the translation conveying device, and the first stacking frame 140 is arranged at the upper end of the second side plate 130; the spacing adjustment device adjusts the distance between the first stacking frame 140 and the second stacking frame 150 by adjusting the distance between the first side plate 120 and the second side plate 130; wherein the first side plate 120 and the second side plate 130 arranged on both sides of the translation conveying device can provide a limit for the jig transported on the translation conveying device to prevent the jig from tipping over; at the same time, by adjusting the distance between the first side plate 120 and the second side plate 130, the stacking part and the conveying part can be adapted to jigs of different sizes at the same time, without the need to adjust multiple parts and the conveying part separately, thereby saving production time.

[0042] like Figure 4 As shown, an adjustment rail 191 is provided on the base 110 , and an adjustment slider 192 is connected to the adjustment rail 191 , and the adjustment slider 192 is connected to the second side plate 130 .

[0043] like Figure 3 As shown, a tray dividing device 160 is provided on the first side plate 120, and the tray dividing device 160 includes a tray dividing block 162 that can be inserted between two stacked jigs. A lifting mechanism 170 is provided on the base 110, and the lifting mechanism 170 is used to lift the stacked jigs between the first stacking frame 140 and the second stacking frame 150; during the feeding process, the stacked jigs can be lowered by the lifting mechanism 170 first, and then the tray dividing block 162 is controlled to be inserted between the first jig and the second jig from the bottom to the top, and then the lifting mechanism 170 is controlled to continue to descend, so that the bottom jig is separated from the jigs stacked above it, and then the separated jigs are placed on the translation conveying device for transportation; wherein, the separated jigs can be prevented from being placed on the translation conveying device by a pushing device or a clamp, etc., and the translation conveying device can also be extended to the bottom of the jig stack so that the jig can be lowered onto the translation conveying device.

[0044] like Figure 3 As shown, the disk dividing block 162 can be inserted between the two fixtures under the drive of the disk dividing cylinder 161 arranged on the first side plate 120, or the disk dividing block 162 can be inserted by controlling the motor or manually.

[0045] like Figure 3 As shown, in order to prevent uneven force on the fixture caused by the single-sided arrangement of the disk dividing block 162, which may lead to damage to the fixture, a disk dividing device 160 is provided on both the first side plate 120 and the second side plate 130.
