Technical Field
[0001] This utility model relates to the field of varistor cutting machine technology, and in particular to an automatic waste edge collection device for varistor cutting machine. Background Technology
[0002] In the field of electronic component manufacturing, varistors, as important protective components, are experiencing continuous growth in demand. Their production process requires cutting the varistor substrate using a cutting machine to obtain products that meet specifications. This cutting process generates a large amount of waste material. If not handled properly and promptly, this will affect the cleanliness of the production environment and production efficiency. Therefore, waste material collection devices have become a key supporting equipment for varistor cutting production lines.
[0003] Currently, waste edge collection in varistor cutting machines largely relies on manual assistance or simple mechanical structures. Manual collection requires operators to be on-site in real time, manually sorting, cutting, and securing the waste edges. This is not only labor-intensive but also prone to errors that cause the waste edges to scatter or be cut irregularly, affecting production continuity. While simple mechanical collection devices can initially wind up the waste edges, they lack an automatic mechanism to adjust the tension of the waste strip. If the waste strip is too loose, it can easily become loose and shift; if it is too tight, it can easily break. Furthermore, manual intervention is required for cutting and securing after the material is full, making it difficult to achieve full-process automation and failing to meet the demands of efficient and stable modern production. Therefore, to address this technical problem, this application proposes an automatic waste edge collection device for varistor cutting machines. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic waste collection device for a pressure-sensitive resistor cutting machine. The device uses an arc-shaped vacuum suction cup to pick up the tape, an air-expanding shaft to roll up the waste, an electric push rod to cut the waste after the tape is full, and a hydraulic system to lock the waste in place. When the tape becomes loose or tight, the controller starts the motor to adjust the tension, and a spring assists in buffering to prevent loosening and breakage, thereby improving efficiency and ensuring quality.
[0005] To achieve the above objectives, the present invention provides the following technical solution: An automatic waste edge collection device for a pressure-sensitive resistor cutting machine includes a cutting machine body. A fixed plate is fixedly connected to the front side of the cutting machine body. An air shaft is provided at the front end of the fixed plate. A winding roller is provided on the outer wall of the air shaft. A hydraulic main pipe is fixedly connected to the middle end of the fixed plate. A second hydraulic piston rod is provided at the bottom end of the hydraulic main pipe. A cutting component is provided on the bottom side of the second hydraulic piston rod. An electric push rod is provided on the outer side wall of the fixed plate. A hydraulic branch pipe is fixedly connected to the outer front wall of the fixed plate. An adhesive component is provided at the output end of the hydraulic branch pipe. Two through slots are opened in the middle of the fixed plate. A slider is slidably connected to the inner wall of the through slot. An elastic component is provided on the inner wall of the slider. The side of one of the sliders is connected to the fixed plate through a winding component. A guide rod is rotatably connected to the outer wall of the slider.
[0006] Furthermore, the adhesive assembly includes a hydraulic piston rod 1 disposed at the output end of the hydraulic branch pipe, and an arc-shaped vacuum suction cup is fixedly connected to the outer wall of the hydraulic piston rod 1.
[0007] Furthermore, the elastic component includes a slide rod fixedly connected to the inner wall of the through groove, the slider is disposed on the outer wall of the slide rod, and a spring is disposed on the outer wall of the slide rod.
[0008] Furthermore, the winding assembly includes a winding roller rotatably connected to the bottom side of the middle end of the fixed plate. A traction rope is provided on the outer wall of the winding roller. One end of the traction rope is connected to the outer wall of one of the sliders. A guide wheel is rotatably connected to the outer wall of the middle end of the fixed plate. The two sliders are connected by a connecting rope, which is provided on the outer wall of the guide wheel.
[0009] Furthermore, the cutting assembly includes a cutting blade disposed on the bottom side of the hydraulic piston rod, a cutting plate is fixedly connected to the bottom side of the fixing plate, and the cutting blade is disposed on the top side of the cutting plate.
[0010] Furthermore, the drive end of the electric push rod is fixedly connected to the bottom end of the hydraulic piston rod.
[0011] Furthermore, a motor is mounted on the bottom side of the middle end of the fixed plate via a fixing frame, and the drive end of the motor is fixedly connected to the outer wall of the winding roller.
[0012] Furthermore, the top end of the hydraulic main pipe and the outer wall of the upper hydraulic branch pipe are connected by a drain pipe, and the two hydraulic branch pipes are connected by a connecting hydraulic pipe.
[0013] This utility model has the following beneficial effects: 1. In this utility model, an arc-shaped vacuum suction cup automatically picks up the tape, and an air-expanding shaft carries a winding roller to roll up the waste material. After the material is full, an electric push rod drives a cutting blade to cut it, and a hydraulic system links the arc-shaped vacuum suction cup. Finally, the material is automatically fixed with tape, reducing labor intensity, avoiding errors, and improving the continuity and efficiency of collection.
[0014] 2. In this utility model, when the waste material belt is loose or tight, the controller starts the motor, which moves the sliding block and presses the spring with the winding roller, and the other sliding block is linked to adjust the tension with the guide rod; if the tension is too high, the spring returns to its original position. Active adjustment plus passive buffering prevents the waste material belt from becoming loose or breaking, ensuring stable winding and high quality. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Reference Figures 2-4This utility model provides an embodiment of an automatic waste edge collection device for a pressure-sensitive resistor cutting machine, comprising a cutting machine body 1, a fixing plate 2 fixedly connected to the front side of the cutting machine body 1, an air expansion shaft 5 provided at the front end of the fixing plate 2, a winding roller 6 provided on the outer wall of the air expansion shaft 5, a hydraulic main pipe 3 fixedly connected to the middle end of the fixing plate 2, a hydraulic piston rod 13 provided at the bottom end of the hydraulic main pipe 3, a cutting blade 14 provided on the bottom side of the hydraulic piston rod 13, a cutting plate 9 fixedly connected to the bottom side of the fixing plate 2, the cutting blade 14 provided on the top side of the cutting plate 9, an electric push rod 10 provided on the outer wall of the side of the fixing plate 2, and a hydraulic branch pipe 4 fixedly connected to the outer wall of the front end of the fixing plate 2, and an output of the hydraulic branch pipe 4. The hydraulic piston rod 11 at the end is fixedly connected to the outer wall of the hydraulic piston rod 11 with an arc-shaped vacuum suction cup 7. Two through slots are opened in the middle of the fixed plate 2. A slider 16 is slidably connected to the inner wall of the through slot. A slide rod 15 is fixedly connected to the inner wall of the through slot. The slider 16 is set on the outer wall of the slide rod 15. A spring 17 is set on the outer wall of the slide rod 15. A winding roller 8 is rotatably connected to the bottom side of the middle end of the fixed plate 2. A traction rope is set on the outer wall of the winding roller 8. One end of the traction rope is connected to the outer wall of one of the sliders 16. A guide wheel 20 is rotatably connected to the outer wall of the middle end of the fixed plate 2. The two sliders 16 are connected by a connecting rope. The connecting rope is set on the outer wall of the guide wheel 20. A guide rod 18 is rotatably connected to the outer wall of the slider 16. Specifically, the arc-shaped vacuum suction cup 7, fixed to the outer wall of the hydraulic piston rod 11 at the output end of the hydraulic branch pipe 4, uses its own adsorption function to adsorb and fix the tape. Then, the winding roller 6 is assembled to the outer wall of the air expansion shaft 5 at the front end of the fixed plate 2. The air expansion shaft 5 is connected to an external drive source, which drives the air expansion shaft 5 to rotate. The winding roller 6 rotates synchronously with the air expansion shaft 5, thereby winding and collecting the waste material generated by the cutting machine. During the winding and collection process, if it is necessary to adjust the tension of the waste tape, it can be achieved through the cooperation of the winding roller 8 on the bottom side of the middle end of the fixed plate 2 and related components: start the drive component to drive the winding roller 8 to rotate, and the winding roller 8 winds the traction rope on the outer wall to pull... A rope pulls a slider 16 connected to it. The slider 16 is slidably connected to the inner wall of the through groove in the middle of the fixed plate 2 and is sleeved on the outer wall of the slide rod 15 fixed in the through groove. When the slider 16 moves, it will compress the spring 17 on the outer wall of the slide rod 15. At the same time, the other slider 16, guided by the guide wheel 20 rotatably connected to the outer wall of the middle of the fixed plate 2, moves away from the first slider 16 through the connecting rope between the two sliders 16. When the spring 17 returns to its original position, it drives the two sliders 16 to move closer together. The guide rod 18 rotatably connected to the outer wall of the slider 16 moves with the slider 16, thereby adjusting the tension of the waste strip that passes over the outer wall of the guide rod 18 to ensure the stability of the winding process. Once the winding roller 6 is full of waste material, the electric push rod 10 on the outer side wall of the fixing plate 2 is activated. The electric push rod 10 drives the cutting blade 14 on the bottom side of the hydraulic piston rod 13 at the bottom of the hydraulic main pipe 3 to move downwards, cooperating with the cutting plate 9 fixed to the bottom side of the fixing plate 2 to precisely cut the waste material. Simultaneously, as the hydraulic piston rod 13 moves downwards with the electric push rod 10, the hydraulic oil in the hydraulic main pipe 3 is drawn into the hydraulic branch pipe 4, causing the arc-shaped vacuum suction cup 7 and the hydraulic piston rod 11 to slightly displace on the inner wall of the hydraulic branch pipe 4. After cutting, the electric push rod 10 drives the hydraulic piston rod 13 upwards, pushing the hydraulic oil in the hydraulic main pipe 3 to the hydraulic branch pipe 4. The hydraulic oil pushes the hydraulic piston rod 11 to extend, causing the arc-shaped vacuum suction cup 7 to move towards the winding roller 6. Finally, the two arc-shaped vacuum suction cups 7 cover the surface of the waste material strip on the outer wall of the winding roller 6, using the adsorbed adhesive tape to stick and fix the waste material strip, completing one automatic collection process.
[0019] Reference Figures 1-3 An electric push rod 10 is provided on the outer side wall of the fixed plate 2. The driving end of the electric push rod 10 is fixedly connected to the bottom end of the hydraulic piston rod 13. A motor 19 is installed on the bottom side of the middle end of the fixed plate 2 through a fixing frame. The driving end of the motor 19 is fixedly connected to the outer wall of the winding roller 8. The top end of the hydraulic main pipe 3 and the outer wall of the upper hydraulic branch pipe 4 are connected through a drain pipe. The two hydraulic branch pipes 4 are connected through a connecting hydraulic pipe 12. Specifically, the device is equipped with a suitable controller as the core control unit, which can pre-set the trigger logic and action sequence for waste material edge winding and collection. When the device is started, the controller first confirms the initial state of each component through the preset program, such as the winding roller 6 being assembled to the air expansion shaft 5 and the arc-shaped vacuum suction cup 7 being in the state of waiting to absorb the tape. Then, the hydraulic oil is made to flow smoothly in the pipeline through the drain pipe connected to the top of the hydraulic main pipe 3 and the connecting hydraulic pipe 12 between the two hydraulic branch pipes 4, pushing the hydraulic piston rod 11 at the output end of the hydraulic branch pipe 4 to move the arc-shaped vacuum suction cup 7 away from the winding roller. After step 6, tape adsorption is completed. When the air shaft 5, driven by an external drive source, starts winding the winding roller 6 to wind the waste material edge, the controller receives signals from the waste tape tension detection component, such as a sensor, in real time. The controller can select the appropriate sensor as needed. If the waste tape is detected to be loose or too tight, the controller immediately sends a drive command to the motor 19 mounted on the bottom side of the fixed plate 2 via a fixed frame. The motor 19 drives the winding roller 8 to rotate, adjusting the position of the slider 16 through the cooperation of the traction rope, connecting rope, and guide wheel 20, thereby adjusting the guide rod 18 to adjust the waste tape tension. The tension of the conveyor belt is adjusted until it returns to the preset range. The controller then sends a stop command to stop motor 19. When the winding roller 6 is full of waste material, this can be determined by the position sensor or winding time. The controller then sends an action command to the electric push rod 10 on the outer side wall of the fixed plate 2. The drive end of the electric push rod 10 pushes the hydraulic piston rod 13, which is fixedly connected to it, downwards. This causes the cutting blade 14 to cooperate with the cutting plate 9 to complete the cutting. Simultaneously, the downward movement of the hydraulic piston rod 13 causes the hydraulic oil in the main hydraulic pipe 3 to flow through the pipeline to the hydraulic branch pipe 4, driving the arc-shaped vacuum... After the suction cup 7 retracts slightly and the cutting action is completed, the controller controls the electric push rod 10 to reverse its driving end, which drives the hydraulic piston rod 13 to move upward, pushing the hydraulic oil in the hydraulic main pipe 3 to be transported in reverse to the hydraulic branch pipe 4. This causes the hydraulic piston rod 11 to drive the arc-shaped vacuum suction cup 7 to extend and cover the surface of the waste tape with the tape to complete the fixation. Finally, the controller sends a signal to prompt the operator to remove the winding roller 6 and reset the status of each component to prepare for the next collection process. For the motor 19, a motor with a self-locking function can be selected according to the actual use.
[0020] Working principle: First, the tape is adsorbed by the arc-shaped vacuum suction cup 7. Then, the winding roller 6 is installed on the outer wall of the air shaft 5. The air shaft 5 is driven by an external drive source to rotate, which can wind and collect the waste material edges generated by the cutting machine. During the winding process, if it is necessary to adjust the tension of the waste tape, the motor 19 can be started. The motor 19 drives the winding roller 8 to rotate and wind the traction rope. The traction rope pulls a slider 16 connected to it to move along the slide rod 15, while compressing the spring 17. The other slider 16 moves away from the first slider 16 under the transmission action of the guide wheel 20 and the connecting rope. When the spring 17 returns to its original position, it will drive the two sliders 16 to move closer together, thereby adjusting the tension of the waste tape through the guide rod 18 on the slider 16. When the winding roller 6 is full of waste material edges, the electric push rod 10 is started, which drives the cutting blade. 14 moves downwards, cooperating with the cutting plate 9 on the bottom side of the fixed plate 2 to complete the cutting of the waste edge. At the same time, the electric push rod 10 drives the hydraulic piston rod 13 to move downwards, so that the hydraulic oil inside the hydraulic main pipe 3 is drawn into the hydraulic branch pipe 4, causing the arc-shaped vacuum suction cup 7 and the hydraulic piston rod 11 to slightly displace on the inner wall of the hydraulic branch pipe 4. After the cutting is completed, the electric push rod 10 drives the hydraulic piston rod 13 to move upwards, pushing the hydraulic oil in the hydraulic main pipe 3 through the drain pipe and connecting hydraulic pipe 12 to be transported to the upper and lower hydraulic branch pipes 4. The hydraulic oil pushes the hydraulic piston rod 11 in the hydraulic branch pipe 4 to extend out, thereby driving the two arc-shaped vacuum suction cups 7 to move towards the winding roller 6. Finally, the two arc-shaped vacuum suction cups 7 cover the waste strip surface on the outer wall of the winding roller 6, and use the adsorbed tape to stick and fix the waste strip on the winding roller 6, completing one automatic waste edge collection process.
[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
