Description

Technical Field

[0001] The utility model relates to the technical field of ornament machines, in particular to an ornament machine. Background Art

[0002] See attached Figure 1 , shown is a rubber blank, which needs to be placed in a vulcanizer for further vulcanization to obtain a finished product. Currently, when vulcanizing the rubber blank, the rubber blank is first transported to the vicinity of the vulcanizer by a conveyor belt, and then a worker manually places the rubber blanks one by one on the mold of the vulcanizer for vulcanization.

[0003] However, when placing rubber blanks manually one by one, on the one hand, the efficiency of manual placement mainly depends on the physical strength of the workers. As the working time increases and the physical strength is gradually consumed, the efficiency of placement will also decrease. On the other hand, the quality of vulcanization will also be limited by the placement position of the rubber blanks on the mold. Therefore, the vulcanization quality also depends on the placement skills of the workers. Thirdly, since the number of rubber blanks placed in each batch is large, workers will cause visual fatigue after a long time of placement, so the problem of missing placement often occurs.

[0004] Therefore, there is an urgent need for a placement machine that can replace manual labor to mechanically place rubber blanks, so as to improve the efficiency and quality of placement and prevent missed placement. Utility Model Content

[0026] The present invention will be described clearly and completely below with reference to the embodiments.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] In the description of the embodiments, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, connections through an intermediary medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on their specific circumstances.

[0029] See attached Figure 1, shown is the rubber blank 1 described in the background technology, which now needs to be placed in a vulcanizer 22 for vulcanization to obtain a finished product. Therefore, the utility model proposes a placement machine for efficiently placing the rubber blank 1 on the vulcanizer 22.

[0030] See attached Figure 2-6 , shown is a piece placing machine, comprising a frame 2, on which is provided a manipulator 3, which is a three-axis manipulator, wherein the execution end of the manipulator 3 is provided with a picking unit, the picking unit comprising a first mounting plate 4 connected to the execution end of the manipulator 3, two first driving cylinders 5 are installed on the first mounting plate 4, and a negative pressure suction head 6 is installed at the output end of the first driving cylinder 5. During operation, the manipulator 3 moves the entire picking unit to the top of the conveyor belt, and then the first driving cylinder 5 is used to control the negative pressure suction head 6 to move downward to achieve adsorption and picking of the rubber blank 1;

[0031] A displacement jacking unit is provided on one side of the frame 2, and a pendulum unit is connected to the displacement jacking unit, wherein the pendulum unit includes a U-shaped mounting frame 7, one end of which is provided with a fixing plate 21, a pressure plate 8 is fixed in the mounting frame 7 by bolts, and one side of the pressure plate 8 is connected to a base plate 9 by bolts;

[0032] A plurality of receiving holes 10 capable of receiving the rubber blank 1 are equidistantly provided on the base plate 9, and shift fork fingers are symmetrically provided at both ends of the receiving opening, one end of the shift fork finger 11 is connected to a shift fork rod 12, one end of the shift fork rod 12 is provided with a driving source 15, and the driving source 15 is mounted on the fixed plate 21. When in use, the two shift fork fingers 11 are driven by the shift fork rod 12 and the driving source 15 to move closer to or away from each other. When the rubber blank 1 is picked up by the negative pressure suction head 6, the shift fork fingers 11 at both ends of the receiving hole 10 are moved closer to each other under the action of the driving source 15. At this time, when the rubber blank 1 is placed in the receiving hole 10, it will sit on the two shift fork fingers 11. When the rubber blank 1 is dropped, the two shift fork fingers 11 are controlled to separate from each other by the driving source 15, and the rubber blank 1 will fall from the receiving hole 10.

[0033] The displacement lifting unit includes a second mounting plate 16, one side of the second mounting plate 16 is provided with a slide rail along the length direction, a slide plate is slidably provided on the slide rail, and two second driving cylinders 17 are installed on the slide plate. The output end of the second driving cylinder 17 is connected to the fixed plate 21. When in use, the second driving cylinder 17 is used to realize the upward lifting of the entire swing unit. A driving motor 18 is provided at one end of the second mounting plate 16, and a lead screw 19 is provided at the output end of the driving motor 18 and cooperates with the thread of the slide plate. When the rubber blank 1 is placed on the swing unit by using the picking unit, the second driving cylinder 17 is used to lift the entire swing unit upward to realize separation from the frame 2, and then the entire swing unit is moved into the vulcanizer 22 by using the lead screw 19 through the driving motor 18;

[0034] Furthermore, in order to improve the stability of the rubber blank 1 during transportation to the vulcanizer 22, a limiting hole 13 of equal diameter and concentricity is provided on the pressing plate 8 at a position corresponding to the receiving hole 10. The limiting hole 13 increases the depth of the entire receiving hole 10, so that the rubber blank 1 does not slip out of the receiving hole 10 during transportation.

[0035] Furthermore, a positioning guide hole 14 is concentrically provided on the other side of the substrate 9 at a position corresponding to the receiving hole 10. The diameter of the positioning guide hole 14 is larger than the diameter of the receiving hole 10. The positioning guide hole 14 facilitates the accurate positioning of the receiving hole 10 and the mold on the vulcanizer 22 when transporting the rubber blank 1, thereby improving the placement quality of the rubber blank 1 on the mold.

[0036] Furthermore, in order to improve the stability of the fork rod 12 when it moves under the action of the driving source 15, a guide groove 20 is opened between two adjacent accommodating holes 10 along the movement direction of the fork finger 11, and the fork rod 12 is placed in the guide groove 20. The guide groove 20 provides a guide for the movement of the fork rod 12, and at the same time realizes the fitting of the pressure plate 8 and the base plate 9, making the entire structure more compact and stable.

[0037] It can be seen that when the present invention is in use, the manipulator 3 is first used to move the picking unit to the position of the conveyor belt, and then the picking unit picks up the rubber blanks 1 through the first driving cylinder 5 in cooperation with the negative pressure suction head 6 and places them one by one in the receiving holes 10. At this time, the two fork fingers 11 are in a state of being close to each other under the action of the driving source 15, and the rubber blanks 1 fall onto the fork fingers 11. When all the receiving holes 10 are placed, the second driving cylinder 17 is used to lift the entire swing unit upward, and then the driving motor 18 is used to cooperate with the lead screw 19 to lift the entire swing unit upward. Move to the top of the vulcanizer 22 mold. At this time, all the positioning guide holes 14 correspond to the mold one by one. Then the second drive cylinder 17 drops the ornament unit, and the positioning guide holes 14 fall onto the mold. Then the drive source 15 is used to control the fork fingers 11 to separate and make the rubber blank 1 fall onto the mold to achieve the final precise ornament. In this process, the machine completely replaces the manpower to put the batch ornaments on the vulcanizer 22, which improves the efficiency and quality of the ornaments and ensures the vulcanization quality of the subsequent finished parts. At the same time, the use of mechanical ornaments avoids the occurrence of missed ornaments due to visual fatigue of manpower.

[0038] The above description is only a preferred specific embodiment of the present invention and does not limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
