Description

Technical Field

[0001] This utility model relates to the field of rivet conveying technology, and in particular to a rivet conveying device. Background Technology

[0002] Rivets are used as connectors in various fields. Usually, rivets need to be placed manually on the feed head of the rivet gun. However, in mass production, workers are prone to fatigue and errors due to constantly repeating the same action. Manual operation is inefficient. Therefore, automatic rivet feeding devices have emerged on the market.

[0003] For example, patent CN208103057U discloses a rivet feeding unit, a rivet feeding device including the rivet feeding unit, and a riveting device including the rivet feeding device. The rivet is fed out from the vibrating plate and transported to the rivet groove of the rivet distribution unit through the slide rail. The rivet is output with its head facing upward. The driving component opens and drives the sliding block and the rivet distribution block to move in the first direction. At this time, the rivet distribution block is also moved in the second direction by the sliding action of the guide post in the rivet distribution block guide groove. This moves the rivet along the rivet guide groove from the opening end of the rivet guide groove to the top of the rivet outlet through hole and falls into the rivet outlet through hole, and then enters the lower rivet blind hole of the rivet feeding unit. Then, the rivet moves from the lower rivet blind hole to the upper rivet blind hole by sliding along the rivet head groove under the action of the rivet head's gravity. It is then output from the upper rivet blind hole by the gas output by the air supply device and enters the mounting device through the connecting pipe, thereby completing the rivet feeding work.

[0004] The problem with the above technology is that when the rivet is moved above the rivet outlet hole by the rivet block, the rivet will continue to be fed into the rivet groove. At this time, the rivet block has not yet been reset, and the rivet will continue to accumulate in the rivet groove. When the rivet block retracts, it is easy to be blocked by the rivet. In severe cases, the rivet will be stuck, causing the rivet to fall out of the rivet groove.

[0005] Therefore, this application provides a rivet conveying device to solve the above-mentioned technical problems. Utility Model Content

[0008] As a further improvement to the above technical solution, the movable arm is provided with a slide rail, the limiting block is provided with a slide rod, and the slide rod is movably connected to the slide rail.

[0009] As a further improvement to the above technical solution, a guide block is provided on the main body, the guide block is located above the moving arm, the guide block is provided with a guide groove arranged horizontally in the front-back direction, and the limiting block is located in the guide groove.

[0012] As a further improvement to the above technical solution, a conveying slide rail is also included, which is connected to the receiving groove.

[0013] As a further improvement to the above technical solution, the main body is provided with a driving device, which is used to drive the moving arm to move left and right in the slide.

[0014] As a further improvement to the above technical solution, the right end of the partition is an angled portion that gradually slopes from the top to the bottom.

[0015] The beneficial effects of this utility model are as follows: In the first state, the moving arm is located at the leftmost side of the slide, the limiting block is located at the frontmost side of the moving arm, the receiving groove is connected to the limiting groove, and the rivet can enter the limiting groove through the receiving groove; In the second state, the moving arm moves along the right end of the slide, the partition can move to the right with the moving arm until the connection between the receiving groove and the limiting groove is broken, the limiting block can move backward with the moving arm until the rivet on the limiting groove falls into the falling groove, and then the rivet moves to the rivet gun through the falling groove. The partition can prevent the rivet from being continuously fed into the limiting groove during the conveying process, thus preventing the rivet from getting stuck, and can also prevent the limiting block from being blocked by the rivet when returning, thereby improving the conveying efficiency of the rivet.

[0030] Reference Figures 1 to 7 A rivet conveying device includes a main body 1, on which a receiving groove 11 is arranged horizontally in the front-back direction, and a falling groove 12 is arranged vertically inside the main body 1; the main body 1 is also provided with a sliding groove 13 arranged horizontally in the left-right direction, and a movable arm 2 is movably arranged in the sliding groove 13. A limiting block 3 that moves in the front-back direction is drivenly connected to the movable arm 2. The limiting block 3 is located above the falling groove 12 and is provided with a limiting groove 31 that connects the receiving groove 11 and the falling groove 12; a partition 4 is provided on the movable arm 2 to control the connection and disconnection between the receiving groove 11 and the limiting groove 31.

[0031] In the first state, the movable arm 2 is located at the leftmost side of the slide 13, the limiting block 3 is located at the frontmost side of the movable arm 2, the receiving groove 11 is connected to the limiting groove 31, and the rivet can enter the limiting groove 31 through the receiving groove 11.

[0032] In the second state, the moving arm 2 moves along the right end of the slide 13, and the partition 4 can move to the right with the moving arm 2 until the connection between the receiving slot 11 and the limiting slot 31 is broken. The limiting block 3 can move backward with the moving arm 2 until the rivet on the limiting slot 31 falls into the falling slot 12. Then the rivet moves to the rivet gun through the falling slot 12. The partition 4 can prevent the rivet from being continuously fed into the limiting slot 31 during the conveying process, thus preventing the rivet from getting stuck. It can also prevent the limiting block 3 from being blocked by the rivet when it returns, thereby improving the conveying efficiency of the rivet.

[0033] In a preferred embodiment, the movable arm 2 is provided with a slide rail 21, and the limiting block 3 is provided with a slide rod 32, which is movably connected to the slide rail 21.

[0034] In a preferred embodiment, a guide block 5 is provided on the main body 1, the guide block 5 is located above the movable arm 2, and a guide groove 51 is provided on the guide block 5, which is horizontally arranged in the front-back direction. The limiting block 3 is located in the guide groove 51.

[0035] In a preferred embodiment, the slide rail 21 includes a first slide rail 22 horizontally arranged in the left-right direction and a second slide rail 23 having a certain angle with the first slide rail 22;

[0036] When the movable arm 2 moves left and right on the slide 13, the slide rod 32 can slide between the first slide rail 22 and the second slide rod 23. The guide groove 51 can restrict the movement direction of the limiting block 3, so that the limiting block 3 moves back and forth with the movement of the movable arm 2.

[0037] In a preferred embodiment, a top cover 6 is provided on the top of the main body 1, and a U-shaped groove 61 with a front opening is provided on the top cover 6. The U-shaped groove 61 is located above the receiving groove 11 and the limiting groove 31.

[0038] When the limiting block 3 moves backward a certain distance, the rivet on the limiting groove 31 can abut against the U-shaped groove 61, thereby disengaging the rivet from the limiting groove 31 and causing the rivet to fall into the drop groove 12.

[0039] In a preferred embodiment, a conveying slide rail 7 is also included. The conveying slide rail 7 is connected to the receiving groove 11 and is connected to an external vibrating plate, which can convey rivets to the receiving groove 11.

[0040] In a preferred embodiment, a driving device (not shown in the figure) is provided on the main body 1. The driving device is used to drive the moving arm 2 to move left and right in the slide 13.

[0041] The drive unit consists of an electric motor and a cylinder.

[0042] In a preferred embodiment, the right end of the partition 4 is an angled portion that gradually slopes from the top to the bottom;

[0043] When the moving arm 2 moves to the right, the oblique part of the partition 4 is inserted between the receiving groove 11 and the limiting groove 31, so that the rivets in the receiving groove 11 and the limiting groove 31 are isolated from each other. During the movement, the partition 4 will abut against the rivets in the limiting groove 31 and make the rivets vertical, thereby preventing the lower part of the rivets from sticking in the receiving groove 31 and causing the rivets to get stuck.

[0044] Usage effect:

[0045] The vibrating disc feeds rivets to the conveying slide rail 7. The rivets can enter the limiting groove 31 through the slide rail 7 and the receiving groove 11. At this time, the moving arm 2 is driven by the driving device to move along the right end of the slide groove 13. The partition 4 can move to the right with the moving arm 2, so that the partition 4 disconnects the connection between the receiving groove 11 and the limiting groove 31. At the same time, when the moving arm 2 moves to the right, it can drive the slide rod 32 from the first slide rail 22 to the second slide rail 23, so that the limiting block 3 moves along the rear end of the guide groove 51. When the limiting block 3 moves a certain distance backward, the rivets on the limiting groove 31 can abut against the U-shaped groove 61, so that the rivets are disengaged from the limiting groove 31 and fall into the falling groove 12. Finally, the rivets move to the rivet gun through the falling groove 12.

[0046] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
