Description

Technical Field

[0001] The present application relates to the technical field of automobile parts processing, and in particular to a feeding structure. Background Art

[0002] In the production of automotive riveted parts, traditional production processes are highly dependent on manual or semi-automatic equipment, especially in the critical link of nailing. To improve production efficiency, many manufacturers have adopted a material belt conveying method, that is, the parts to be processed are conveyed in the form of a continuous material belt. This production method first uses a punching machine to continuously punch holes on the material belt to form the initial part shape. Subsequently, the stamped material belt is conveyed to the nailing machine for riveting. Finally, a cutting machine is used to cut the parts on the material belt into individual finished products.

[0003] However, during the material belt conveying process, when the punching machine works slower than the nailing machine, the material belt between the two is prone to become tight. On the contrary, when the nailing machine works slower than the punching machine, the material belt between the two is in a loose state. If the material belt is too tight, it may cause breakage, while if it is too loose, it may cause flipping and entanglement, thereby affecting production efficiency and product quality. Utility Model Content

[0004] In response to the deficiencies in the prior art, the present application provides a feeding structure with advantages such as automatic monitoring, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a feeding structure comprising a monitoring frame, wherein the top of the monitoring frame is fixedly connected to a top plate, the bottom of the monitoring frame is fixedly connected to a bottom plate, a side of the monitoring frame is provided with a through chute, and a monitoring float is slidably connected to the interior of the chute;

[0006] A first proximity switch is installed on the upper surface of the monitoring float and the inner top wall of the monitoring frame respectively, and the two first proximity switches are optically connected;

[0007] The bottom of the monitoring float and the inner bottom wall of the monitoring frame are respectively installed with second proximity switches, and the two second proximity switches are optically connected.

[0008] Through the above scheme, by using the monitoring float in conjunction with the first proximity switch and the second proximity switch, when the material belt is tight, the monitoring float moves upward, and when the material belt is loose, the monitoring float moves downward, thereby realizing real-time monitoring of the tight and loose states of the material belt. Once an abnormal state is detected, the sound and light alarm can be triggered immediately, effectively avoiding the problem of the material belt breaking due to excessive tension or flipping and winding caused by loose accumulation, thereby significantly improving the stability and reliability of the production line.

[0009] Furthermore, an audible and visual alarm is installed on the upper surface of the top plate.

[0010] Through the above solution, by setting up the sound and light alarm, an alarm can be issued when the material belt is abnormal, so that workers can handle it in time.

[0011] Furthermore, two U-shaped sliding sleeves are fixedly connected to the outer surface of the monitoring float, and the two U-shaped sliding sleeves are both slidably connected to the monitoring frame.

[0012] Through the above solution and the provision of the U-shaped sliding sleeve, the stability of the monitoring float when it moves up and down can be improved.

[0013] Furthermore, the monitoring float is made of engineering plastic.

[0014] According to the above solution, by setting the detection float to be an engineering plastic material, the pressure of the monitoring float on the material strip can be effectively reduced, thereby avoiding deformation of the material strip.

[0015] Furthermore, the outer surfaces of the two U-shaped sliding sleeves are fixedly connected to two damping sleeves, the interiors of the two damping sleeves are fixedly connected to a first magnet, and two second magnets are installed on the upper surface of the base plate. Each of the first magnets is on the same axis as the second magnet adjacent to it, and the adjacent ends of the first magnet and the second magnet are set to the same pole.

[0016] According to the above solution, by setting the ends of the first magnet and the second magnet close to each other to the same pole, a damping effect can be generated when the monitoring float falls freely after the material strip processing is completed, thereby effectively avoiding a rapid collision between the two second proximity switches.

[0017] Furthermore, a microprocessor is installed on the upper surface of the top plate, and the first switch, the second switch and the sound and light alarm are all electrically connected to the microprocessor.

[0018] Through the above solution, the purpose of controlling the electrical components can be achieved through the setting of the microprocessor.

[0019] Furthermore, the bottom plate is made of metal material.

[0020] According to the above solution, by setting the bottom plate to metal material, the overall center of gravity can be improved, and the tipping of the monitoring frame can be effectively alleviated.

[0021] Furthermore, a plurality of guide grooves of different sizes are formed on one side of the monitoring float.

[0022] Through the above scheme, by setting the guide groove, the purpose of limiting and guiding the material strip can be achieved, avoiding the deviation and flipping of the material strip. At the same time, guide grooves of different sizes facilitate the application of material strips of different sizes, thereby improving the overall practicality.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0024] This feeding structure uses a monitoring float in conjunction with a first proximity switch and a second proximity switch. When the material belt is tight, the monitoring float moves upward, and when the material belt is loose, the monitoring float moves downward, thereby realizing real-time monitoring of the tight and loose states of the material belt. Once an abnormal state is detected, an audible and visual alarm can be triggered immediately, effectively avoiding the problem of the material belt breaking due to excessive tension or flipping and winding caused by loose accumulation, thereby significantly improving the stability and reliability of the production line.

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] See also Figure 1 、 Figure 2 and Figure 4 A feeding structure in this embodiment includes a monitoring frame 1, the top of the monitoring frame 1 is fixedly connected to a top plate 2, the bottom of the monitoring frame 1 is fixedly connected to a bottom plate 3, a side of the monitoring frame 1 is provided with a through slide 4, and the inside of the slide 4 is slidably connected to a monitoring float 5, and the monitoring float 5 is set to an engineering plastic material. By setting the detection float to an engineering plastic material, the pressure of the monitoring float 5 on the material belt can be effectively reduced, thereby avoiding deformation of the material belt.

[0033] See also Figure 1 、 Figure 2 and Figure 4 The upper surface of the monitoring float 5 and the inner top wall of the monitoring frame 1 are respectively installed with a first proximity switch 6, and the two first proximity switches 6 are optically connected. When the nailing machine works faster than the punching machine, the material belt between the two is gradually in a short-material and tight state. The monitoring float 5 moves upward, and the two first proximity switches 6 approach, thereby achieving the purpose of monitoring the material belt and effectively avoiding the breakage of the material belt. The outer surface of the monitoring float 5 is fixedly connected to two U-shaped sleeves 9, and the two U-shaped sleeves 9 are both slidably connected to the monitoring frame 1. Through the setting of the U-shaped sleeve 9, the stability of the monitoring float 5 when moving up and down can be improved.

[0034] See also Figure 1 、 Figure 2 and Figure 3 The bottom of the monitoring float 5 and the inner bottom wall of the monitoring frame 1 are respectively installed with a second proximity switch 7, and the two second proximity switches 7 are optically connected; when the nailing machine works slower than the punching machine, the material strip between the two gradually becomes too loose, the monitoring float 5 moves downward, and the two second proximity switches 7 approach, thereby achieving the purpose of monitoring the material strip and effectively avoiding the accumulation and entanglement of the material strip.

[0035] See also Figure 1 、 Figure 2 and Figure 3 , an audible and visual alarm 8 is installed on the upper surface of the top plate 2. Through the setting of the audible and visual alarm 8, an alarm can be sounded when the material strip is abnormal, which is convenient for workers to deal with in time. The outer surfaces of the two U-shaped sliding sleeves 9 are fixedly connected to two damping sleeves 10, and the interiors of the two damping sleeves 10 are fixedly connected to the first magnet 11. Two second magnets 12 are installed on the upper surface of the bottom plate 3. Each first magnet 11 is on the same axis as the second magnet 12 adjacent to it. The ends of the first magnet 11 and the second magnet 12 that are close to each other are set to the same pole. By setting the ends of the first magnet 11 and the second magnet 12 that are close to each other to the same pole, after the material strip processing is completed, a damping effect can be generated when the monitoring float 5 falls freely, effectively avoiding the rapid collision of the two second proximity switches 7.

[0036] See also Figure 1 、 Figure 2 and Figure 3A microprocessor 13 is installed on the upper surface of the top plate 2. The first switch, the second switch and the sound and light alarm 8 are all electrically connected to the microprocessor 13. Through the setting of the microprocessor 13, the purpose of controlling the electrical components can be achieved. The bottom plate 3 is made of metal material. By setting the bottom plate 3 as a metal material, the overall center of gravity can be improved, and the tipping of the monitoring frame 1 can be effectively slowed down. A plurality of guide grooves 14 of different sizes are provided on one side of the monitoring float 5. Through the setting of the guide grooves 14, the purpose of limiting and guiding the material belt can be achieved to avoid the deviation and flipping of the material belt. At the same time, guide grooves 14 of different sizes are convenient for the application of material belts of different sizes, thereby improving the overall practicality.

[0037] A feeding structure in this embodiment uses a monitoring float 5 in conjunction with a first proximity switch and a second proximity switch 7. When the material belt is tight, the monitoring float 5 moves upward, and when the material belt is loose, the monitoring float 5 moves downward, thereby realizing real-time monitoring of the tight and loose states of the material belt. Once an abnormal state is detected, the sound and light alarm 8 can be triggered immediately to alarm, effectively avoiding the problem of the material belt breaking due to excessive tension or flipping and winding caused by loose accumulation, thereby significantly improving the stability and reliability of the production line.

[0038] The working principle of the above embodiment is as follows: under normal working conditions, the material belt is transmitted between the punching machine and the nailing machine at a certain speed, and the monitoring float 5 is located at the initial position in the monitoring frame 1. At this time, the first proximity switch 6 and the second proximity switch 7 are both in the disconnected state. When the working speed of the nailing machine is too faster than that of the punching machine, the material belt between the two will gradually be in a short-stacked and tense state. This tense state will cause the material belt to generate an upward thrust on the monitoring float 5, causing the monitoring float 5 to move upward along the slide 4 on the monitoring frame 1. As the monitoring float 5 rises, the first proximity switch 6 installed on its upper surface gradually approaches another first proximity switch 6 on the top wall of the monitoring frame 1. When the distance between the two is close enough, the first proximity switch 6 is triggered and sends a signal to the microprocessor 13. The microprocessor 13 receives the first proximity switch 6, it will immediately determine that the material strip is in a tight state, and control the sound and light alarm 8 to send out an alarm signal to remind workers to pay attention and take corresponding treatment measures, such as adjusting the working speed of the nailing machine to avoid the material strip from breaking due to excessive tension. On the contrary, when the working speed of the nailing machine is too slow than that of the punching machine, the material strip will gradually accumulate between the two, forming a loose state. At this time, the thrust of the material strip on the monitoring float 5 is reduced, and the monitoring float 5 moves downward along the slide 4 under the action of its own gravity or a slight pull of the material strip. As the monitoring float 5 descends, the second proximity switch 7 installed at its bottom gradually approaches another second proximity switch 7 on the inner bottom wall of the monitoring frame 1. When the distance between the two is close enough, the signal will also be triggered, and the sound and light alarm 8 will be controlled by the microprocessor 13 to alarm, reminding workers to pay attention to the problem of loose accumulation of the material strip.
