Description

Technical Field

[0001] This invention belongs to the field of chain plate detection technology, specifically relating to a toothed chain plate mixed piece detection device. Background Technology

[0002] Currently, there are many models of toothed chains on the market, and mixed pieces are prone to occur during assembly. Mixed pieces refer to chain plates with small differences in outline size or inconsistent tooth shape and thickness. During manual inspection, it is difficult to pick out all chain plates with inconsistent tooth shape, large size, and inconsistent thickness by visual inspection or simple tools, which leads to problems in subsequent toothed chain assembly processes and may even directly affect the quality of the chain. In addition, relying on manual inspection greatly reduces the efficiency of toothed chain assembly. Utility Model Content

[0003] This invention discloses a toothed chain plate mixed plate detection device, which automatically identifies and picks out mixed chain plates with inconsistent tooth shape, large size, and inconsistent thickness, so as to improve the assembly efficiency of toothed chains, ensure the assembly quality of toothed chains, save labor, and overcome the defects of low efficiency and many errors of manual inspection.

[0004] To achieve the above objectives, the technical solution of this invention is as follows:

[0005] A toothed chain plate mixed sheet detection device includes a robotic arm, a movable feeding pipe, a base, a laser detection device, and a chain plate guide rail. The base is fixedly mounted on the top of the outer wall of the chain plate guide rail. The base is fixed to a set position by a connector. The movable feeding pipe is connected above the base. The chain plate guide rail and the front end of the base are provided with a through groove. A laser detection device for detecting the thickness of the chain plate is provided at the front of the base opposite to the through groove. The end of the robotic arm is connected to a magnet for adsorbing mixed chain plates. The shape and size of the inner cavity of the chain plate guide rail are matched with qualified chain plates.

The laser scanning detector is fixed to a set position two in front of the base and opposite to the through groove by a fixing seat. Two through holes of the same height are provided in the inner cavity of the chain guide rail and inside the base. The through holes are set horizontally and penetrate the inner and outer walls of the base. A first cylinder is also set horizontally on the outer side of the base opposite to the through holes. The telescopic end of the first cylinder is connected to a support plate that slides with the through holes. When the two support plates extend into the inner cavity of the chain guide rail, they stop the mixed unqualified chain plates. The cylinder barrel of the first cylinder is fixed to a set position three by a cylinder fixing seat.

[0007] Preferably, the movable feeding tube includes a feeding tube body with a rectangular inner cavity and rounded corners. The inner wall of the feeding tube body is provided with an elastic rubber layer. The elastic rubber layer is slidably connected to a chain plate passing through the feeding tube body. Several chain plates are stacked and arranged inside the feeding tube body. The front end of the feeding tube body is provided with a through observation hole.

[0008] Preferably, L-shaped connecting rods are fixedly connected to the left and right ends of the feed pipe body, and a reaction plate is connected between the tops of the vertical sections of the two connecting rods. A second cylinder is provided at the lower end of the reaction plate along the longitudinal direction. The fixed end of the second cylinder is fixedly connected to the reaction plate, and a pusher plate is connected to the telescopic end.

Detailed Implementation

[0020] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0021] The following embodiments can be understood as a part of the local structure or method of the present invention, or as a combination of embodiments to explain the connotation of a larger range of structures or methods of the present invention.

[0022] Example 1

[0023] A toothed chain plate mixed sheet detection device, such as Figure 1-5 As shown, the system includes a robotic arm 3, a movable feeding pipe, a base 22, a laser detection device 1, and a chain plate guide rail 23. The base 22 is fixedly mounted on the top of the outer wall of the chain plate guide rail 23. The base 22 is fixed to a set position 1 by a connector. The movable feeding pipe is connected above the base 22. The front end of the chain plate guide rail 23 and the base 22 is provided with a through groove. The laser detection device 1 for detecting the thickness of the chain plate is provided at the front of the base 22 opposite to the through groove. The end of the robotic arm 3 is connected to an electromagnet 4 for adsorbing mixed chain plates. The shape and size of the inner cavity of the chain plate guide rail 23 are matched with qualified chain plates.

[0024] The four settings of this new type can be set according to the production site as needed. The chain plate guide rail is used to transport qualified toothed chain plates, while the movable feed pipe is used to transport chain plate raw materials mixed with unqualified products. When passing the top of the chain plate guide rail, chain plates with inconsistent tooth shape or slightly larger size are intercepted. At this time, the movable feed pipe moves away, and the robotic arm takes out the intercepted unqualified chain plates through an electromagnet. After taking them out, the movable feed pipe is reset.

[0025] Example 2

[0026] like Figure 1 , 2 As shown, the laser detection device 1 is a laser scanning detector, which is fixed to a predetermined position two in front of the base 22 opposite to the through slot via a fixing base. Figure 3As shown, two through holes 8 of equal height are provided in the inner cavity of the chain guide rail 23 and in the base 22. The through holes 8 are set horizontally and penetrate the inner and outer walls of the base 22. On the outer side of the base 22 opposite to the through holes, a first cylinder 5 is also set horizontally. The telescopic end of the first cylinder 5 is connected to a support plate 6 that slides with the through holes. When the two support plates 6 extend into the inner cavity of the chain guide rail 23, they cut off the mixed unqualified chain plates (referring to chain plates with unqualified thickness). The cylinder barrel of the first cylinder 5 is fixed in the set position three by the cylinder fixing seat.

[0027] In this embodiment, when a chain plate with unqualified thickness enters the chain plate guide rail, the laser detection device 1 detects that the chain plate has unqualified thickness. The controller controls the first cylinder to extend and the chain plate is stopped by the pallet 6. Then the movable feed pipe is moved away, and the robotic arm removes the unqualified chain plate by means of an electromagnet.

[0028] Example 3

[0029] like Figure 1-5 As shown, the movable feeding tube includes a feeding tube body 21 with a rectangular inner cavity and rounded corners. The inner wall of the feeding tube body 21 is provided with an elastic rubber layer (not shown in the figure). The elastic rubber layer is damped and slidably connected to a chain plate passing through the feeding tube body 21. Several chain plates are stacked and arranged inside the feeding tube body 21. The front end of the feeding tube body 21 is provided with a through observation hole.

[0030] like Figure 5 As shown, L-shaped connecting rods 9 are fixedly connected to the left and right ends of the feed tube body 21, respectively. A reaction plate (not marked in the figure) is connected between the top of the vertical sections of the two connecting rods 9. A second cylinder 10 is provided at the lower end of the reaction plate along the longitudinal direction. The fixed end of the second cylinder 10 is fixedly connected to the reaction plate, and the telescopic end is connected to a pusher plate 13. The pusher plate 13 is used to extend into the feed tube body 21 and push the chain plate 7 downward to discharge. A third cylinder 11 is also provided at the top of the reaction plate. The fixed end of the third cylinder 11 is fixedly connected to the mounting plates 12 at four designated positions, and the telescopic end extends downward along the longitudinal direction and is fixedly connected to the top of the reaction plate.

[0031] The extension end of the second cylinder 10 is connected to the pusher plate 13 via a pressure sensor.

[0032] In this embodiment, the purpose of setting the elastic rubber layer is to achieve orderly control of the sequential feeding of the chain plates and to prevent all the chain plates from falling off when the feeding tube body is removed. The second cylinder is used to push the material, that is, to push the chain plate to the detection position 221 at the top of the inner cavity of the chain plate guide. If the thickness of the chain plate is qualified, the chain plate 7 is conveyed downward along the chain plate guide. If the tooth shape of the chain plate is different from that of the qualified chain plate or the size is slightly larger, it cannot enter the chain plate guide. At this time, the pressure sensor detects a signal, and the controller controls the third cylinder to remove the feeding tube body.

[0033] Example 4

[0034] The mixed-film detection device is also equipped with a mixed chain plate collection box (not shown in the figure) on one side for use with a robotic arm.

[0035] like Figure 1 As shown, it also includes a controller, and the first cylinder 5, the second cylinder 10, the third cylinder 11, the robotic arm 3, the laser detection device 1, the pressure sensor, and the electromagnet 4 are electrically connected to the controller.

[0036] This embodiment provides an automated mode for detecting mixed products on chain plates. The controller is preferably a PLC controller. At the same time, the controller can also count the number of qualified chain plates according to a preset program. The control method and counting program of the relevant components are existing technologies and will not be described in detail.
