Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0033] like Figure 1-Figure 5 As shown, the utility model provides an adjustment mechanism, including an adjustment plate 1, an adjustment slot 2, an adjustment shaft 3, and a locking member 4; wherein:

[0034] The adjustment slot 2 is provided on one side of the adjustment plate 1;

[0035] The adjusting shaft 3 is movably arranged in the adjusting groove 2 and can move along the adjusting groove 2;

[0036] The cylinder 5 is connected to the adjustment shaft 3;

[0037] The manipulator 6 is rotatably connected to the other side of the adjustment plate 1;

[0038] The locking members 4 are respectively installed between the adjusting shaft 3 and the adjusting slot 2 and between the manipulator 6 and the adjusting plate 1 to lock the position of the manipulator 6 that has been adjusted into place.

[0039] The regulating mechanism provided by the present invention changes the start and stop positions of the cylinder 5 through the regulating slot 2, thereby changing the position of the manipulator 6, and realizing the adjustable angle of the manipulator 6.

[0040] Specifically, such as Figure 2 As shown, the adjustment plate 1 is a triangular structure; the manipulator 6 is rotatably connected to one corner of the adjustment plate 1 through a rotating shaft 7; and the adjustment slot 2 is provided between the other two corners of the adjustment plate 1.

[0041] In order to enable flexible and convenient adjustment and to achieve angle adjustment, in this embodiment, the adjustment groove 2 is an arc-shaped groove. Furthermore, the adjustment groove 2 is an inwardly protruding arc-shaped groove, and both ends of the adjustment groove 2 extend to the two corners of the adjustment plate 1 respectively.

[0042] It should be noted that the inward direction referred to here refers to the direction from the outer edge of the adjustment plate 1 to the center.

[0043] In order to avoid interference, save materials and reduce costs, in this embodiment, one side edge of the adjustment plate 1 corresponding to the adjustment slot 2 is an arc-shaped edge, and the curvature of the arc-shaped edge is equal to the curvature of the adjustment slot 2.

[0044] In order to prevent displacement after position adjustment, in this embodiment, the two active positions are respectively locked. Specifically, Figure 2 and Figure 4 As shown, the locking member 4 includes a first locking member 4 and a second locking member 4 ; the first locking member 4 is installed between the adjustment shaft 3 and the adjustment slot 2 ; the second locking member 4 is installed between the manipulator 6 and the adjustment plate 1 .

[0045] Furthermore, the first locking member 4 includes a spring washer 41 and a locking washer 42; the adjusting shaft 3 is a threaded shaft; the spring washer 41 and the locking washer 42 are both sleeved on the adjusting shaft 3 and respectively abut against the two side walls of the adjusting slot.

[0046] As an optional embodiment of the present invention, the second locking member 4 includes an adjusting block 43; both sides of one end of the adjusting block 43 extend outward to form a first clamping plate 431 and a second clamping plate 432; the first clamping plate 431 and the second clamping plate 432 are arranged in parallel and opposite to each other to form a clamping portion for clamping the adjusting plate 1 therebetween; the first clamping plate 431 and the second clamping plate 432 are correspondingly provided with through-axis holes for the rotating shaft 7 to pass through; an adjusting slit 433 connected to the through-axis hole is opened at the other end of the adjusting block 43 to form adjusting arms 434 on both sides of the adjusting slit 433; adjusting screw holes 435 are correspondingly provided on the two adjusting arms 434; the adjusting screw is screwed in the two adjusting screw holes 435, and when the screwing depth of the adjusting screw is different, the width of the adjusting slit 433 is different.

[0047] In order to reduce weight and save costs, in this embodiment, at least one weight-reducing hole is provided on the adjustment plate 1 .

[0048] like Figure 1-Figure 5 As shown, the present invention provides a manipulator 6, comprising a cylinder 5, a fork arm 8, a pneumatic finger 9 and an adjustment mechanism;

[0049] In order to make the robot universal and enable the pneumatic fingers 9 to stop at multiple positions, the place where the injection molding robot 6 connects to the adjustment shaft of the cylinder 5 is designed as an arc groove. According to the actual position of the injection molding machine product, the adjustment shaft of the cylinder 5 is fixed in the arc groove, which allows the pneumatic gripper of the injection molding robot 6 to start and stop at different positions and rotate a certain angle.

[0050] Specifically, the pneumatic finger 9 is movably arranged on the fork arm 8;

[0051] The fork arm 8 is mounted on the injection molding machine and is connected to the adjustment mechanism via the rotating shaft 7;

[0052] The cylinder 5 is connected to the regulating mechanism via a movable joint 10 .

[0053] In this embodiment, there are two pneumatic fingers 9, which are respectively used to clamp different positions of the product.

[0054] During use, after the injection molding robot 6 is installed on the injection molding machine, it is necessary to install and debug the mold, confirm the position of the product in the mold, and then confirm where the product is to be placed.

[0055] When adjusting the position, first turn off the air source, then manually rotate the fork arm 8, which can rotate around the rotation axis 7. The rotation axis 7 is provided on the adjustment plate 1, and the adjustment plate 1 can rotate around the rotation axis 7. At this time, the fork arm 8 and the adjustment plate 1 can rotate around the rotation axis 7 together.

[0056] The two pneumatic fingers can reciprocate along the fork arm 8 or rotate around the rotating shaft 7 like the fork arm 8. Therefore, after determining the product's position, the two pneumatic fingers can be manually moved and rotated so that the two pneumatic fingers 9 can grasp the product. Once the position is determined, the status of the cylinder 5 is checked to see whether it is extended or retracted. Regardless of whether it is extended or retracted, the cylinder 5 must be at its maximum extension or retraction position. This can be achieved by adjusting the position of the adjustment shaft within the adjustment slot. After adjusting the position, the adjustment shaft is finally fixed so that the adjustment shaft on the cylinder 5 is fixed at a certain position in the arc slot. After adjusting one side, the other side is adjusted. With the cylinder 5 at its other maximum position, the two pneumatic fingers are moved to a safe space. This space can be used to place a storage box or an assembly line. The product grasped by the pneumatic fingers 9 can be placed in the storage box or on the assembly line and flow to the next workstation.

[0057] It should be noted that the pneumatic fingers, fork arms, cylinders and other structures in the present invention are all existing technologies. No improvements have been made to these parts this time, so they will not be described in detail.

[0058] During the implementation process, attention should be paid to the buffering of the cylinder 5. If the buffering provided by the cylinder 5 is not enough, additional buffering should be added. For example, the cylinder 5 can be equipped with a separate pressure regulating valve to accurately control the pressure and prevent excessive impact from causing damage to parts or products. A spring gasket 41 is provided on the adjusting shaft to prevent the adjusting shaft from changing its position in the arc groove due to the length of use, thereby locking the position of the adjusting shaft. In addition, the part where the rotating shaft 7 and the adjusting plate are connected is locked and tightened by providing an adjusting block, because the loosening of the rotating shaft 7 on the adjusting plate 1 will cause position changes, thereby preventing the pneumatic finger 9 from grabbing the product. In the process of adjusting the movement of the pneumatic finger 9 along the fork arm 8, the positioning block is mainly adjusted. Similarly, the positioning block should also be locked on the rotating shaft 7 so as not to loosen due to the passage of time. After the overall adjustment is completed, the position of the adjusting shaft in the arc groove and the position of the two-finger positioning block on the rotating shaft should be marked, and then a trial run is required, running at no load for a certain period of time. If the above positions do not change, it can be run with load.

[0059] The manipulator 6 of the present invention utilizes an arc groove to change the start and stop positions of the device, and utilizes a positioning block to move and lock on the turntable to adjust the start and end positions of the execution end.
