DETAILED DESCRIPTION

[0034] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.

[0035] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0036] See also Figure 1 The present embodiment provides an automatic loading and unloading structure of a precision engraving machine, comprising a base 10, a conveying assembly 20, a bracket 30, a precision engraving machine 40, a first driving assembly 50 and an adsorption assembly 60. The conveying assembly 20 is arranged on the upper part of the base 10 for conveying the workpiece. The bracket 30 is fixedly mounted on the upper part of the base 10. The precision engraving machine 40 is mounted on one side of the bracket 30. The first driving assembly 50 and the adsorption assembly 60 are movably arranged on a side wall of the bracket 30. The adsorption assembly 60 is used to adsorb the workpiece transported by the conveying assembly 20. The first driving assembly 50 is used to drive the adsorption assembly 60 to rotate, so as to rotate the workpiece adsorbed by the adsorption assembly 60 to the side of the precision engraving machine 40.

[0037] When the workpiece needs to be engraved, the conveying component 20 can be used to convey the workpiece. When the workpiece moves to the bottom of the adsorption component 60, the adsorption component 60 adsorbs the workpiece, and then the first driving component 50 is used to drive the adsorption component 60 to rotate, and then the workpiece is rotated to the side of the engraving machine 40, and the workpiece is engraved by the engraving machine 40.

[0038] See also Figure 1 , Figure 2 and Figure 4In one embodiment, the adsorption assembly 60 includes a plunger rod 601, a rotating support and an adsorption sleeve 606. The rotating support is rotatably mounted on one side of the bracket 30. The plunger rod 601 passes through the rotating support and movably cooperates with the rotating support. The adsorption sleeve 606 is movably sleeved on the bottom of the plunger rod 601. The bottom of the adsorption sleeve 606 is provided with an adsorption hole 611. The side wall of the adsorption sleeve 606 is provided with an exhaust pipe 610. A one-way valve is provided in the exhaust pipe 610. The first driving assembly 50 includes a motor (FIG. ), an incomplete gear 501, a connecting rod 502, a pressure rod 503 and a first tooth piece 505, the motor is fixedly mounted on one side of the bracket 30, a plurality of the first tooth pieces 505 are fixedly arranged on one side of the plunger rod 601 and are spaced apart along the length direction of the plunger rod 601, one side of the incomplete gear 501 is connected to the output end of the motor through a driving shaft 504, the incomplete gear 501 can mesh with a plurality of the first tooth pieces 505, one end of the connecting rod 502 is connected to the driving shaft 504, and the other end is connected to the pressure rod 503.

[0039] When the workpiece moves to the bottom of the adsorption sleeve 606, the driving shaft 504 is driven to rotate by the motor. When the driving shaft 504 rotates, it can drive the pressure rod 503 to move in a circle through the connecting rod 502, and on the other hand, it drives the incomplete gear 501 to rotate. When the incomplete gear 501 rotates, it drives the plunger rod 601 to move downward compared to the rotating support through its meshing action with the first teeth 505, thereby driving the adsorption sleeve 606 to move downward. When the adsorption sleeve 606 moves downward, its bottom acts on the upper surface of the workpiece, and then the plunger rod 601 continues to move downward to The air inside the adsorption sleeve 606 is pressed out from the exhaust pipe 610, so that the inside of the adsorption sleeve 606 is in a negative pressure state, and then the workpiece is adsorbed to the bottom of the adsorption sleeve 606 through the adsorption hole 611, and then the pressure rod 503 acts on one side of the plunger rod 601 with the rotation of the connecting rod 502, thereby pushing the plunger rod 601 to rotate with the rotating support as the rotation base point, thereby driving the adsorption sleeve 606 and the workpiece adsorbed to the bottom of the adsorption sleeve 606 to rotate, so that the workpiece rotates to the side of the precision engraving machine 40, and the precision engraving machine 40 is used to engrave the workpiece.

[0040] See also Figure 1 and Figure 3In one embodiment, the rotating support member includes a positioning sleeve 602 and a rotating rod 603, one end of the rotating rod 603 is rotatably connected to the side wall of the bracket 30, and the other end is fixedly connected to the positioning sleeve 602, the plunger rod 601 passes through the positioning sleeve 602 and movably cooperates with the positioning sleeve 602, and the side wall of the plunger rod 601 is also fixedly provided with an annular stopper 605, and the positioning sleeve 602 and the annular stopper 605 are also connected by a first elastic member 604, and the first elastic member 604 is used to provide elastic pulling force to the annular stopper 605.

[0041] When the incomplete gear 501 is engaged with the first teeth 505, the plunger rod 601 can be driven to move downward compared to the positioning sleeve 602. At this time, the first elastic member 604 is stretched. When the workpiece is adsorbed to the bottom of the adsorption sleeve 606, the incomplete gear 501 is disengaged from the first teeth 505. At this time, the first elastic member 604 pulls the annular stopper 605 to drive the plunger rod 601 to move upward compared to the positioning sleeve 602, and then drives the adsorption sleeve 606 to move upward to remove the workpiece from the upper part of the conveying assembly 20. Then the pressure rod 503 acts on the side wall of the plunger rod 601 to drive the plunger rod 601 to rotate. When the plunger rod 601 rotates, the rotating rod 603 rotates adaptively compared to the bracket 30, and then the workpiece adsorbed to the bottom of the adsorption sleeve 606 is rotated to the side of the engraving machine 40, and the workpiece is engraved by the engraving machine 40.

[0042] See also Figure 3 In one embodiment, a second elastic member 609 is further provided inside the adsorption sleeve 606, and the upper end of the second elastic member 609 is connected to the bottom of the plunger rod 601, and the other end is connected to the inner bottom wall of the adsorption sleeve 606, so as to provide elastic support for the adsorption sleeve 606. A second air inlet groove 608 is provided at the bottom edge of the plunger rod 601 along the length direction, and a first air inlet groove 607 is provided at the upper edge of the adsorption sleeve 606. A second driving assembly 70 is also provided on one side of the bracket 30. When the workpiece is engraved, the second driving assembly 70 is used to drive the adsorption sleeve 606 to rotate relative to the plunger rod 601, so as to drive the first air inlet groove 607 to adjust to be aligned and connected with the second air inlet groove 608.

[0043] When the plunger rod 601 drives the adsorption sleeve 606 to move downward to adsorb the workpiece on the upper part of the conveying assembly 20, the second elastic member 609 is compressed by force. At this time, the first air inlet groove 607 and the second air inlet groove 608 are in a mutually misaligned state. When the workpiece is engraved, the motor drives the drive shaft 504 to rotate in the opposite direction, thereby driving the incomplete gear 501 to rotate in the opposite direction and driving the pressure rod 503 to move in the opposite circular motion. When the pressure rod 503 moves in the opposite circular motion, the plunger rod 601 rotates in the opposite direction around the rotating rod 603 under the action of its own gravity, thereby driving the workpiece to rotate in the opposite direction, so as to rotate the engraved workpiece back to the top of the conveying assembly 20. In this process, The second driving component 70 drives the adsorption sleeve 606 to rotate relative to the plunger rod 601. When the adsorption sleeve 606 rotates, the first air inlet groove 607 can be rotated to the side of the second air inlet groove 608, so that the two are aligned and connected with each other. When the first air inlet groove 607 is connected with the second air inlet groove 608, the outside air can enter the adsorption sleeve 606 through the first air inlet groove 607 and the second air inlet groove 608, so that the negative pressure environment inside the adsorption sleeve 606 is destroyed, and the workpiece can no longer be adsorbed to the bottom of the adsorption sleeve 606. The workpiece falls from the bottom of the adsorption sleeve 606 to the conveying component 20 by itself, and is continued to be conveyed by the conveying component 20.

[0044] See also Figure 3 In one embodiment, the second driving assembly 70 includes a gear 701, a second tooth piece 702, a third elastic member 703 and an arc plate 704, wherein the arc plate 704 is fixedly disposed on the side wall of the bracket 30, and the second tooth piece 702 is provided with a plurality of groups, and a plurality of second tooth pieces 702 are spaced apart on a side of the arc plate 704 away from the bracket 30, and each group of the second tooth pieces 702 is hingedly connected to the arc plate 704, and each group of the second tooth pieces 702 is connected to the arc plate 704 through a group of the third elastic member 703, and the third elastic member 703 is used to provide elastic support for the second tooth piece 702, and the gear 701 is fixedly disposed on the outside of the adsorption sleeve 606.

[0045] When the motor drives the pressure rod 503 to move in a circular motion to rotate the workpiece to one side of the precision engraving machine 40, the gear 701 outside the suction sleeve 606 acts on the plurality of second tooth plates 702 to drive the plurality of second tooth plates 702 to adaptively deflect on one side of the arc plate 704. At this time, the plurality of tooth plates 702 cannot push the gear 701 to rotate, that is, the suction sleeve 606 cannot rotate compared with the plunger rod 601, and the first air inlet groove 607 and the second air inlet groove 608 are in a mutually misaligned state; when the workpiece is engraved, the motor drives the pressure rod 503 to move in a reverse circular motion, and the plunger rod 601, the suction sleeve 606 and the workpiece rotate in the reverse direction under the action of gravity. At this time, the gear 701 can act on the plurality of second tooth plates 702 in the reverse direction, and then enter a meshing state with the plurality of second tooth plates 702. The plurality of second tooth plates 702 can push the gear 701 and then drive the suction sleeve 606 to rotate compared with the plunger rod 601, thereby making the first air inlet groove 607 It rotates to the side of the second air inlet groove 608 so that the two are aligned and connected to each other, and then the outside air enters the adsorption sleeve 606 from the first air inlet groove 607 and the second air inlet groove 608, so that the negative pressure environment inside the adsorption sleeve 606 is destroyed, and the workpiece can no longer be adsorbed to the bottom of the adsorption sleeve 606. The workpiece falls from the bottom of the adsorption sleeve 606 to the conveying component 20 and is continued to be conveyed by the conveying component 20; in the above process, when the adsorption sleeve 606 rotates compared with the plunger rod 601, the second elastic member 609 can be adaptively twisted, and when the gear 701 is disengaged from the second teeth 702, the rotation of the second elastic member 609 can drive the adsorption sleeve 606 to rotate in the opposite direction compared with the plunger rod 601, so that the first air inlet groove 607 and the second air inlet groove 608 are in a mutually misaligned state again, so as to facilitate further adsorption of the workpiece subsequently conveyed by the conveying component 20.

[0046] In one embodiment, the first elastic member 604 , the second elastic member 609 and the third elastic member 703 may be springs or metal springs, which are not limited here.

[0047] See also Figure 1 In one embodiment, the conveying assembly 20 includes two groups of belt rollers 202 and a conveyor belt 201 arranged between the two groups of belt rollers 202. The two groups of belt rollers 202 are respectively arranged at the two ends of the upper part of the base 10. Both ends of the two groups of belt rollers 202 are provided with fixed seats for rotation through a rotating shaft. The fixed seats are fixedly connected to the upper surface of the base 10. One group of the belt rollers 202 is controlled to rotate by an external motor (not shown in the figure).

[0048] By placing the workpiece on the upper part of the conveyor belt 201, using an external motor to drive one set of belt rollers 202 to rotate, and then driving the conveyor belt 201 to operate, the conveyor belt 201 can convey the workpiece to the bottom of the adsorption sleeve 606 when it is running, and then be adsorbed by the adsorption sleeve 606 and transferred to the side of the precision engraving machine 40 to achieve the engraving processing of the workpiece.

[0049] In the embodiment of the present invention, when it is necessary to engrave the workpiece, the conveying component 20 can be used to convey the workpiece. When the workpiece moves to the bottom of the adsorption component 60, the adsorption component 60 adsorbs the workpiece, and then the first driving component 50 is used to drive the adsorption component 60 to rotate, and then the workpiece is rotated to the side of the precision engraving machine 40, and the workpiece is engraved by the precision engraving machine 40. Compared with the prior art, automatic loading and engraving of the workpiece can be realized. At the same time, after the workpiece is engraved, automatic unloading of the workpiece can also be realized, which has the advantages of good workpiece engraving effect and high engraving efficiency.

[0050] The preferred implementation modes of the present application are described in detail above, but the present application is not limited to the above implementation modes, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present application.
