[0034] See Figure 1-4 , Figure 7 As shown, this embodiment provides an automatic gripping device for a mold. The mold 1 includes a cylindrical body 11, a limiting shaft 12 connected to the top of the cylindrical body 11, and an annular pressure plate 13 protruding from the upper part of the limiting shaft 12. The axis of the limiting shaft 12 is parallel to the axis of the cylindrical body 11. The automatic gripping device includes a robotic arm 2, a mounting base 3 connected to the robotic arm 2, and a gripping device along a first direction (i.e., ... Figure 2 The through hole 4 formed by the mounting base 3 (direction A) in the second direction (i.e., direction A) includes a through hole 4 formed by the second direction (i.e., direction A) in ... Figure 2 The first branch hole 41 and the second branch hole 42 are connected sequentially in direction B. The first direction is perpendicular to the second direction and parallel to the limiting shaft 12. The diameter of the first branch hole 41 is larger than the diameter of the annular pressure plate 13, and the diameter of the second branch hole 42 is greater than or equal to the diameter of the limiting shaft 12 and smaller than the diameter of the annular pressure plate 13. The cylindrical body 11 includes a left mold, a right mold and a bottom mold.

[0035] See Figure 3 As shown, the above-mentioned automatic gripping device further includes a clamping assembly 5 that is telescopically mounted on the mounting base 3 in a second direction, and a pressing assembly 6 that is telescopically mounted on the mounting base 3 in a first direction. The clamping assembly 5 is used to drive the mold 1 to move in the second direction when extended, so that the limiting shaft 12 enters from the first dividing hole 41 and abuts against the second dividing hole 42; the pressing assembly 6 is used to drive the mold 1 to move in the first direction when extended, so that the annular pressure plate 13 abuts against the mounting base 3.

[0036] Specifically, once the automatic gripping device is in position, it drives the mounting base 3 downwards so that the first dividing hole 41 fits into the annular pressure plate 13. At this time, the clamping assembly 5 extends and drives the mold 1 to move in the second direction, pushing the limiting shaft 12 from the first dividing hole 41 into the second dividing hole 42, and pressing the limiting shaft 12 against the second dividing hole 42 in the second direction. Then, the pressing assembly 6 extends and drives the mold 1 to move in the first direction, causing the annular pressure plate 13 to press downwards against the mounting base 3. The two work together to press the limiting shaft 12 against the second dividing hole 42 from two directions, achieving fast and efficient automatic gripping of the mold 1, thereby ensuring the efficiency of changing the blow molding machine mold 1.

[0037] In this embodiment, there are two through holes 4, which are spaced apart along a direction perpendicular to the second direction, and their arrangement direction is as follows: Figure 2 The top of the cylindrical body 11 is provided with two limiting shafts 12, and two through holes 4 are used to fit the two limiting shafts 12 one-to-one. Through this setting, the mold 1 can be oriented for gripping and placement, further improving the efficiency of changing the blow molding machine mold 1.

[0038] See Figure 8 As shown, the upper end face of the cylindrical body 11 is provided with a marker point 14 and a midline 15 passing through the marker point 14. The automatic gripping device also includes a vision detection component 7 provided on the mounting base 3. The vision detection component 7 is used to capture the position of the marker point 14 and the position of the midline 15, and then adjust the mounting base 3 to the gripping position by the robot arm.

[0039] In this embodiment, the two limiting shafts 12 are symmetrically arranged relative to the center line 15. When the mounting base 3 is in the gripping position, the center line 15 is parallel to the second direction, and the two first dividing holes 41 are respectively aligned with the corresponding limiting shafts 12 along the first direction. During gripping, simply drive the mounting base 3 to move downwards, so that the two first dividing holes 41 are respectively fitted into the two annular pressure plates 13. Then, the clamping assembly 5 extends and drives the mold 1 to move along the second direction, pushing the two limiting shafts 12 from the first dividing holes 41 into the second dividing holes 42, and pressing the limiting shafts 12 against the second dividing holes 42 along the second direction. Finally, the pressing assembly 6 extends and drives the mold 1 to move along the first direction, so that the two annular pressure plates 13 press downwards against the mounting base 3.

[0040] See Figure 5 As shown, the mounting base 3 is in the gripping position at this time, and the two first holes 41 are aligned with the corresponding limiting shafts 12 along the first direction; see also Figure 6 As shown, the two limiting shafts 12 enter the second dividing hole 42 respectively, indicating that the gripping is complete.

[0041] The aforementioned clamping assembly 5 includes a first telescopic member 51 that is telescopically mounted on the mounting base 3 in a second direction, and a clamping member 52 connected to the first telescopic member 51 and used to abut against the side of the cylindrical body 11. The end face of the clamping member 52 used to abut against the side of the cylindrical body 11 is an arc surface. In this embodiment, the first telescopic member 51 and the clamping member 52 are respectively located below the mounting base 3, and the bottom of the clamping member 52 is lower than the first telescopic member 51.

[0042] The aforementioned clamping assembly 6 includes a second telescopic member 61 that is telescopically mounted on the mounting base 3 in a first direction, and a clamping member 62 connected to the second telescopic member 61 and used to abut against the upper end face of the cylindrical body 11. In this embodiment, when the clamping member 62 is extended, the clamping member 62 is located below the through hole 4, and the clamping member 62 and the annular pressure plate 13 are located on opposite sides of the through hole 4, that is, the annular pressure plate 13 is located above the through hole 4.

[0043] In this embodiment, there are two sets of clamping components 6 arranged at intervals along a direction perpendicular to the second direction. The two sets of clamping components 6 are respectively located on the outside of the two through holes 4 to avoid interference with the limiting shaft 12.

[0044] The working process of this embodiment is described in detail below:

[0045] When gripping mold 1, the visual inspection component 7 first captures the position of the mark point 14 and the position of the center line 15 corresponding to mold 1. Then, the robot adjusts the mounting base 3 to the gripping position so that the center line 15 is parallel to the second direction, and the two first dividing holes 41 are respectively aligned with the corresponding limiting shafts 12 along the first direction.

[0046] Next, the mounting base 3 is driven downward by the robotic arm, so that the two first dividing holes 41 are respectively fitted into the two annular pressure plates 13;

[0047] Then the clamping assembly 5 extends and drives the mold 1 to move in the second direction, so that the two limiting shafts 12 are respectively pushed into the second dividing hole 42 from the first dividing hole 41, and the limiting shafts 12 are pressed against the second dividing hole 42 in the second direction.

[0048] Finally, the clamping component 6 extends and drives the mold 1 to move along the first direction, pressing the two annular pressure plates 13 downward against the mounting base 3 respectively, thereby realizing the directional automatic gripping of the mold 1.

[0049] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
