Description

Technical Field

[0001] The present invention relates to the technology of link processing, and more specifically, it relates to an automatic detection and feeding module for links. Background Art

[0002] Most chains are composed of components such as links, pins, and bushings. Among them, the existing links mainly include a link body and two through holes opened on the link body. At present, the production of chains requires collecting a large number of links and transporting them to the next party or the next process for subsequent processing. At present, through other detection structures, defective products with the two through holes on one side being connected due to secondary punching on a single link can be excluded. However, after the subsequent material distribution, there are still cases where the links have blind holes or the hole diameters are too small. At present, when feeding the links after the material distribution, it is extremely easy to find that the fed links do not meet the required standards, and it is easy to cause the failure of link feeding due to the offset of the holes on the links, too small hole diameters, or even blind holes.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an automatic detection and feeding module for links, which can detect the offset of the holes on the links, too small hole diameters, or even blind holes, and effectively perform the feeding work at the same time.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: An automatic detection and feeding module for links, comprising:

[0006] An interface seat, provided with a feeding port;

[0007] An interface tail seat, fixedly connected to the interface seat and forming a channel with the interface seat. The channel is communicated with the feeding port, and the entrance to the exit of the channel is inclined from top to bottom;

[0008] A first limiting component, movably connected to the entrance position of the interface tail seat, for controlling the links to enter the detection station one by one;

[0009] A link detection component, arranged at the detection station of the interface tail seat, for detecting whether the current link meets the detection standard;

[0010] A second limiting component, movably connected to the interface tail seat, for blocking the link at the detection station of the channel and allowing the link to pass through to the feeding station when the link meets the detection standard;

[0011] A feeding component, arranged at the feeding station of the interface tail seat, and when the currently detected link meets the detection standard, it moves towards the feeding port direction to push the link for feeding;

[0012] The third limiting component is movably connected to the outlet position of the interface tailstock, and is used to block the chain plates that meet the detection standard outside the outlet, and when the current chain plate does not meet the detection standard, it allows the current chain plate to be discharged from the outlet.

[0013] The present invention is further configured as follows: the first limiting component includes a first telescopic component located on the side of the interface tailstock away from the interface seat, and its output end penetrates through the interface tailstock and is located at the entrance of the channel. The chain plate detection component includes a detection module, which is used to detect the aperture and position of the holes on the chain plate. The second limiting component includes a second telescopic component located on the side of the interface tailstock away from the interface seat. The feeding component includes a third telescopic component located on the side of the interface tailstock away from the interface seat, and its output end penetrates through the interface tailstock and is arranged opposite to the feeding station. The third limiting component includes a fourth telescopic component located on the side of the interface tailstock away from the interface seat, and its output end penetrates through the interface tailstock and is located at the outlet of the channel. The output end of the detection module is coupled to a control component, and the output end of the control component is respectively coupled to the first telescopic component, the second telescopic component, the third telescopic component and the fourth telescopic component.

[0014] By adopting the above technical solution, when people introduce the chain plates into the channel and move them from the entrance of the channel to the outlet direction of the channel, under normal conditions, the first telescopic component is in the shortest length state to keep the entrance of the channel unblocked. The chain plates slide into the channel under the action of their own weight. The second telescopic component extends its output end to limit the chain plates. Then the detection module detects the thickness and orientation of the chain plates. If the indicators of the chain plates are all normal, the second telescopic component retracts to allow the chain plates to continue to slide down. When they move to the position of the output end of the third telescopic component, they are pushed by the output end of the third telescopic component into the discharge port, thus completing normal feeding. However, if the indicators of the chain plates are not normal, the first telescopic component extends its output end to close the entrance of the channel. The second telescopic component retracts to allow the chain plates to continue to slide down. The third telescopic component stops working. The fourth telescopic component also retracts its output end to make the outlet of the channel unblocked, and the chain plates can continue to slide down and leave the channel.

[0015] The present invention is further configured as follows: the detection module includes a selection sensor, and the selection sensor is used to detect the thickness and orientation of the chain plates.

[0016] The present invention is further configured as follows: the detection module further includes a fifth telescopic component arranged on the side of the interface tailstock away from the interface seat. The selection sensor is fixedly connected to the output end of the fifth telescopic component. The output end of the fifth telescopic component penetrates through the interface tailstock and is located between the first telescopic component and the second telescopic component.

[0017] The present invention is further configured such that: the fifth telescopic assembly includes a feeding seat fixedly connected to the output end of the third telescopic assembly, a first picking needle and a second picking needle fixedly connected to the feeding seat, the first picking needle and the second picking needle penetrate through the interface tail seat, and the picking sensor is fixedly connected to the feeding seat.

[0018] The present invention is further configured such that: the third telescopic assembly is a first cylinder, the output end of the first cylinder is a feeding ejector rod, the feeding seat is fixedly connected to the feeding ejector rod, a connecting column is fixedly connected to one side of the feeding seat facing the interface tail seat, a picking needle mounting seat is slidably connected to the side of the connecting column away from the feeding seat, and the first picking needle and the second picking needle are fixedly connected to the picking needle mounting seat.

[0019] By adopting the above technical solution, when the detection module needs to detect the link, the first cylinder can be made to drive the feeding ejector rod to extend, which can drive the feeding seat to displace synchronously, and the feeding seat drives the picking needle mounting seat to displace through the connecting column, so that the first picking needle and the second picking needle can be smoothly inserted into the holes of the link to determine whether the link is standard.

[0020] The present invention is further configured such that: an elastic member is sleeved on the outer side of the connecting column and is located between the picking needle mounting seat and the feeding seat.

[0021] By adopting the above technical solution, by setting the elastic member, the first cylinder does not need to drive its output end to retract. As long as the operation of the first cylinder is stopped and the elastic member releases its elastic potential energy, the feeding ejector rod can be made to retract.

[0022] The present invention is further configured such that: a control piece seat is fixedly connected to the interface tail seat, the control piece seat is in the shape of a folded plate, and the control piece seat is used to shield the outer ring of the channel and the connection between the channel and the working station.

[0023] By adopting the above technical solution, by setting the control piece seat, it can shield the open part of the channel to prevent the link from falling out of the channel.

[0024] In summary, the present invention has the following beneficial effects:

[0025] When people import the chain pieces into the channel and move them from the entrance of the channel towards the exit, under normal conditions, the telescopic component one is in the shortest length state to keep the entrance of the channel unobstructed. The chain pieces slide into the channel under their own weight. The telescopic component two extends its output end to limit the chain pieces. Then, the detection module detects the thickness and orientation of the chain pieces. If the indicators of the chain pieces are all normal, the telescopic component two retracts to allow the chain pieces to continue sliding down. When they move to the position of the output end of the telescopic component three, they are pushed by the output end of the telescopic component three and enter the discharge port, thus completing normal feeding. However, if the indicators of the chain pieces are abnormal, the telescopic component one extends its output end to close the entrance of the channel. The telescopic component two retracts to allow the chain pieces to continue sliding down. The telescopic component three stops working, and the telescopic component four also retracts its output end to make the exit of the channel unobstructed, and the chain pieces can continue to slide down and leave the channel.

[0030] The present invention will be described in detail below with reference to the drawings and embodiments.

[0031] Embodiment:

[0032] An automatic chain sheet detection and feeding module, including an interface seat 9 connected to the workbench by screws. The interface seat 9 is plate-shaped and has a groove at one end. An interface tail seat 8 located in the groove is connected to the interface seat 9 by welding. A channel for the chain sheet to pass through is formed between the interface tail seat 8 and the interface seat 9. And a discharge port 12 communicating with the channel is provided on the interface seat 9. The interface seat 9 is inclined on the tabletop, and the horizontal position height of the entrance of the channel is higher than the horizontal position height of the exit of the channel. A control piece seat 11 is provided on the interface tail seat 8. The control piece seat 11 includes a vertical part with the same vertical direction as the interface tail seat 8, and parallel parts one and two integrally formed at the upper and lower ends of the vertical part. The top surface of the parallel part one is parallel to the top surface of the interface tail seat 8, and the top surface of the parallel part two is parallel to the top surface of the interface seat 9. And a connecting piece 10 is provided between the interface tail seat 8 and the parallel part one. The connecting piece 10 is connected to the interface tail seat 8 and the parallel part one by screws.

[0033] On the side of the interface tail seat 8 far from the interface seat 9, a telescopic component one, a telescopic component two, and a telescopic component four are installed by screw connection. The telescopic component one is a cylinder two 14, the telescopic component two is a cylinder three 13, and the telescopic component four is a cylinder four 15. The output end of the cylinder two 14 is fixedly connected with a limit rod one 21. The limit rod one 21 penetrates through the interface tail seat 8 and is located between the discharge port 12 and the entrance of the channel. The output end of the cylinder three 13 is fixedly connected with a limit rod two 20. The limit rod two 20 penetrates through the interface tail seat 8 and is located at the entrance of the channel. The output end of the cylinder four 15 is fixedly connected with a limit rod three 22. The limit rod three 22 penetrates through the interface tail seat 8 and is located at the exit of the channel.

[0034] An L-shaped plate 1 is connected to the workbench on the side of the interface tail seat 8 far from the interface seat 9 by screws. A telescopic component three is installed on the L-shaped plate 1 by screw connection. The telescopic component three is a cylinder one 2. The output end of the cylinder one 2 is fixedly connected with a feeding ejector rod 3. The feeding ejector rod 3 penetrates through the interface tail seat 8 and is arranged opposite to the discharge port 12.

[0035] A telescopic component five is provided on the feeding ejector rod 3. The telescopic component five includes a feeding seat 4 fixedly connected to the feeding ejector rod 3. A connecting column is welded on the side of the feeding seat 4 far from the feeding ejector rod 3. A selection needle mounting seat 5 is slidably connected to the connecting column. On the side of the selection needle mounting seat 5 far from the feeding seat 4, a selection needle one 18 and a selection needle two 19 are welded. The selection needle one 18 and the selection needle two 19 penetrate through the interface tail seat 8 and are located between the limit rod one 21 and the limit rod two 20. At the same time, an elastic member 17 sleeved on the outer side of the connecting column is provided between the feeding seat 4 and the selection needle mounting seat 5. The elastic member 17 can be a spring.

[0036] An L-shaped sensor seat 6 is installed on the feeding seat 4 by screw connection. A selection sensor 7 which is one of a distance sensor, a straight-line sensor, or a pressure sensor is installed on the sensor seat 6.

[0037] A push button switch is installed on the workbench by means of screw connection. The push button switch is connected to a control component, which is the minimum system of a single-chip microcomputer based on the chip AT89C51. The input ends of the first cylinder 2, the second cylinder 14, the third cylinder 13, and the fourth cylinder 15 are all connected to the output end of the minimum system of the single-chip microcomputer based on the chip AT89C51. The output end of the selection sensor 7 is connected to the input end of the minimum system of the single-chip microcomputer based on the chip AT89C51. The output end of the push button switch is also connected to the input end of the minimum system of the single-chip microcomputer based on the chip AT89C51.

[0038] When people need to perform automatic detection and feeding of link pieces through this module, people can import the link pieces into the channel one by one, and then press the push button switch. After the link piece enters the channel, the link piece is limited by the channel, and since the channel is inclined from top to bottom, the link piece can slide downward under its own gravity. The control component controls the second cylinder 14, so that the limiting rod 21 on the output end of the second cylinder 14 extends and retracts back and forth, so that when the link piece moves downward, it is limited by the limiting rod 21. Then, the first cylinder 2 drives the feeding ejector rod 3 at its output end to extend. The feeding ejector rod 3 will drive the feeding seat 4 to move. The feeding seat 4 will drive the selection needle mounting seat 5 to displace through the connecting column and the elastic member 17, so that the selection needle mounting seat 5 drives the first selection needle 18 and the second selection needle 19 to pass through the interface tail seat 8, and then insert into the two holes of the link piece.

[0039] If the first selection needle 18 and the second selection needle 19 successfully pass through the two holes on the link piece, the displacement sensor detects a correct signal, and the first cylinder 2 stops working. The elastic member 17 releases elastic potential energy, so that the elastic member 17 pushes the feeding seat 4, causing the feeding ejector rod 3 to return to the first cylinder 2. At the same time, the second cylinder 14 drives the limiting rod 21 to retract. The link piece continues to slide under its own weight. When the link piece slides to a position directly opposite the discharge port 12, the next link piece also slides to the position of the previous link piece at the same time. The first cylinder 2 restarts and drives the feeding ejector rod 3 to extend to push the previous link piece, so that the link piece enters the discharge port 12.

[0040] If the picking needle 18 and the picking needle 19 cannot smoothly pass through the two holes on the link, the signal detected by the displacement sensor is different from the original signal, indicating that the holes on the link are offset or the hole diameters do not correspond. As a result, the picking sensor 7 sends a signal to the control component, and the control component will control the cylinder three 13 to extend the limiting rod two 20 on its output end, so that the entrance of the channel is closed. At the same time, the control component controls the cylinder one 2 to stop running, and the elastic member 17 releases elastic potential energy, so that the elastic member 17 pushes the feeding seat 4, causing the feeding ejector rod 3 to return to the cylinder one 2. And the cylinder four 15 controls the limiting rod three 22 on its output end to retract, so that the exit of the channel is unblocked. The link slides under its own weight and leaves the channel, which is convenient for people to recycle. Then, after a certain period of time, the control component controls this module to work again.

[0041] Thus, people can realize the automatic feeding, automatic detection and discharging of the links, improve work efficiency, and can effectively screen and feed the links.

[0042] Moreover, the telescopic component one, the telescopic component two, the telescopic component three and the telescopic component four can all be replaced by a screw-nut structure to achieve the telescopic effect.

[0043] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
