Workpiece multi-material fixture and material box

The invention relates to a workpiece multi-material clamp and a material box, in particular to a clamp structure that can store workpiece materials without collision or tooth damage.

In the past, if you want to send workpiece materials to the processing department for processing, you usually have to rely on manpower to send the workpiece materials one by one to the processing department. After one workpiece material is processed, the workpiece material is taken out, and then another unprocessed workpiece material is sent to the processing department. It is placed in the processing area for processing. However, the traditional feeding method has the annoying problem of being time-consuming and wasting manpower. It is no longer in line with the current feeding method.

Therefore, in order to improve the shortcomings of the traditional feeding method, the industry has specially developed a robotic arm to clamp materials. The front end of the robotic arm is equipped with a clamping claw, and the clamping claw is used to clamp the workpiece material to the processing place for processing. However, the traditional robotic arm , the clamping force of the clamping claw is not large, and it can only clamp a single and light workpiece material. Although the traditional robotic arm can improve the problem of traditional manual feeding, the traditional robotic arm cannot clamp a large amount of workpiece material at one time. The range is quite limited; in addition, traditional robotic arms are limited due to spring elasticity, and traditional robotic arms cannot clamp heavier workpiece materials. Therefore, the effect of traditional robotic arms is still quite limited and does not meet the needs of the industry.

The invention relates to a workpiece multi-material clamp and a material box. It mainly uses a row-setting mechanism to arrange the screw materials in a plurality, and presses the majority of the screw materials through a pressing plate to align with the row-setting mechanism. The feeding mechanism is arranged at the same inclination, and the backing plate is pulled away to create a supporting space at the lower end of the screw head of the screw material, and then through the first and second supporting plates of the supporting mechanism, the angle is linked through the power unit Turn the first supporting plate and the second supporting plate from vertical to horizontal, and simultaneously hold the first and second supporting plates in the horizontal type toward the supporting space created by the screw material, and use The power unit controls the pressure of the first supporting plate, the second supporting plate and the pressing plate, and holds up a large number of screw materials at one time, and then transfers them to the material box through the displacement of the base, so that the workpieces do not collide or damage teeth. The feeding efficiency.

Regarding the explanation of the material supporting action of the present invention, please refer to Figure 7, Figure 8 and Figure 9. First, the adjusting nut 115 on the upper end of the power unit 113 of the adjusting base 11 is used to adjust the angle so that the material supporting mechanism 1 on the base 10 , showing the same tilted material supporting pattern as the feeding track 20; when the power unit 113 is activated, the power unit 113 will retract upward due to the ejector rod 114 and lift the linkage block 112 with the pivot 111 as the fulcrum, resulting in an adjustment. The tilt displacement set by the nut 115 adjusts the parts of the supporting mechanism 1 on the base 10 to the tilt angle, and then moves it to the corresponding top of the feeding track 20 (as shown in Figure 9); when the supporting mechanism 1 moves to the feeding track 20 corresponds upward, a signal is sent to the backing plate 22, and the backing plate 22 uses the third pneumatic cylinder 220 to push the backing plate 22 to the height difference structure 21 of the feeding track 20 (as shown in Figure 10). The upper end surface of the backing plate 22 is flush with the feeding track 20 (as shown in Figure 11), which facilitates the screw materials 3 to follow the feeding track 20 and be arranged upright on the backing plate 22 and the second track 200 (as shown in Figures 12 to 14 ) to wait for the material to be supported, and the limit plate 223 limits the beating of the screw parts 3, so that the screw parts 3 that slide in can remain flat and will not cause uneven heights. Wait until most of the screw parts 3 are arranged. When the height difference structure is at 21 (as shown in Figure 15), a signal is sent to the fourth pneumatic cylinder 152 of the pressure plate 15 (as shown in Figure 16).
