Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a novel servo feeder. Background Technology

[0002] Servo feeders are key equipment on automated production lines, widely used in conjunction with punch presses and other processing equipment to achieve automated, high-precision step-by-step conveying of coil or sheet materials. With the continuous improvement of production efficiency and product precision requirements in modern manufacturing, high-speed precision stamping has become the mainstream development trend.

[0003] In precision stamping processes, dies are typically equipped with guide pins. When the material is fed to the designated position, the guide pin is inserted into the positioning hole of the material before stamping to perform secondary precise positioning of the material, thereby eliminating the cumulative errors generated during the feeding process. In order for the guide pin to successfully position the material, the feeding roller of the servo feeder must release its grip on the material at this moment; this action is called release.

[0004] Some existing servo feeders rely on a complex linkage lever mechanism to achieve their release function. This mechanism is typically connected to the eccentric shaft of the punch press or an independent cam mechanism via a connecting rod, driving the upper feed roller to lift and lower via mechanical transmission. This mechanical linkage method has a long transmission chain with many intermediate links, inevitably resulting in transmission backlash. With long-term operation, these backlashes gradually increase due to wear, causing a lag in the release action, making the timing of release and clamping inaccurate, and even interfering with the movement of the die guide pins, directly affecting the machining accuracy of the final product. At the same time, this complex mechanical structure increases the difficulty of equipment debugging and maintenance, and its reliability and stability face significant challenges under high-speed operation, limiting further improvements in overall stamping efficiency.

[0005] Therefore, this utility model proposes a novel servo feeder to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the new servo feeder, such as complex structure of the relaxation mechanism, long transmission chain, easy generation of transmission gap, resulting in delayed response of relaxation action, insufficient timing and low reliability, this utility model aims to provide a new servo feeder with improved structure that can effectively solve the above problems.

[0007] This utility model provides a novel servo feeder, including a machine body mounting plate, a feeding lower roller rotatably mounted on the machine body mounting plate, and a servo motor fixedly mounted on the machine body mounting plate.

[0008] The power output end of the servo motor is connected to the feed roller drive.

[0009] The new servo feeder also includes a release shaft, a release plate, an upper feeding roller, and a release cylinder. The release shaft is horizontally fixed to the machine body mounting plate. The release plate is rotatably sleeved on the release shaft. The upper feeding roller is rotatably mounted on the release plate and is located directly above the lower feeding roller. The two work together to clamp the material. The release cylinder is fixedly mounted on the machine body mounting plate. The output end of the release cylinder is hinged to the release plate. The action of the release cylinder can directly drive the release plate to rotate around the release shaft, thereby driving the upper feeding roller to achieve lifting or lowering.

[0010] Preferably, the power output end of the servo motor is connected to the lower feeding roller via a synchronous pulley and a synchronous belt. This transmission method ensures the accuracy of power transmission and eliminates slippage error.

[0011] Preferably, a synchronous belt tensioning mechanism is also provided on the transmission path of the synchronous belt. The synchronous belt tensioning mechanism is used to ensure that the synchronous belt maintains appropriate tension during the transmission process, prevents step loss, and ensures feeding accuracy.

[0012] Preferably, a relaxation spring is also connected between the relaxation plate and the machine body mounting plate. The relaxation spring is used to provide an auxiliary restoring force when the relaxation cylinder releases pressure, so that the relaxation plate can drive the feeding roller to descend quickly and press the material.

[0013] Preferably, the bottom of the mounting plate is fixedly connected to a shock-absorbing adhesive. This adhesive is used to absorb vibrations generated during high-speed operation, ensuring stable operation and measurement accuracy of the entire machine.

[0014] Preferably, a front side plate and a rear side plate are fixedly connected to both sides of the mounting plate, and a top cover plate covers the top of the mounting plate. The front side plate and the rear side plate are respectively covered with a front cover and a rear cover. These components together constitute a closed protective shell for the equipment, preventing external impurities from entering the equipment.

[0015] Preferably, an electrical box is also fixedly installed on the mounting plate of the machine body. The electrical box is covered with an electrical box cover, which provides dust protection and protection for the electrical box and protects the internal electrical control system.

[0016] Preferably, the feeding side of the lower feeding roller and the upper feeding roller is provided with a feeding device to guide the material smoothly into the space between the rollers, and the discharge side is provided with a discharge side plate. A pressure gauge is also installed on the machine body mounting plate to display the working air pressure status of the pneumatic system where the release cylinder is located in real time.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of insufficient rigidity of the frame structure and easy vibration in the prior art by setting the machine body mounting plate as the core load-bearing component and installing machine body anti-vibration rubber at its bottom, thereby achieving the technical effects of improving the overall stability of the equipment, reducing operating vibration, and ensuring high-precision feeding.

[0018] 2. This utility model solves the problem of slow response speed of the relaxation mechanism in the prior art by adopting a structure in which the relaxation cylinder directly drives the relaxation plate to rotate around the relaxation shaft, thereby driving the upper roller of the feeding to rise. It achieves the technical effect of rapid relaxation action response, direct and efficient structural transmission, and better coordination with high-frequency stamping dies.

[0019] 3. This utility model solves the problem of unreliable reset of the relaxation mechanism in the prior art by connecting a relaxation spring between the relaxation plate and the machine body mounting plate. It achieves the technical effect of using the spring force to assist the relaxation plate to reset quickly, ensuring that the feeding roller can press the material in time, and improving the reliability of the action cycle.

[0022] 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.

[0023] Please refer to Figures 1 to 4 This utility model provides a novel servo feeder, which aims to solve the problems in the prior art where the frame structure is not rigid enough and easily vibrates, affecting the feeding accuracy, and the response speed and reset reliability of the release mechanism need to be improved.

[0024] like Figure 1 and Figure 4 As shown, the servo feeder includes a mounting plate 1, which serves as the core load-bearing component of the equipment. A lower feeding roller 10 is rotatably mounted on the mounting plate 1, and a servo motor 5 is also fixedly mounted on the mounting plate 1. The power output end of the servo motor 5 is connected to the lower feeding roller 10. The new servo feeder also includes a release shaft 9, a release plate 12, an upper feeding roller 11, and a release cylinder 18. The release shaft 9 is horizontally fixed on the mounting plate 1, the release plate 12 is rotatably sleeved on the release shaft 9, the upper feeding roller 11 is rotatably mounted on the release plate 12, and the upper feeding roller 11 is located directly above the lower feeding roller 10. The release cylinder 18 is fixedly mounted on the mounting plate 1, and the output end of the release cylinder 18 is hinged to the release plate 12 to drive the release plate 12 to rotate around the release shaft 9, thereby driving the upper feeding roller 11 to rise or fall.

[0025] To achieve precise power transmission, the transmission connection in this embodiment specifically includes a synchronous pulley 7, a synchronous belt, and a synchronous belt tensioning mechanism 19.

[0026] Please refer to the following carefully. Figure 1 The power transmission structure will now be described in detail: The power output end of the servo motor 5 and the shaft end of the feeding roller 10 are respectively fixedly connected to the synchronous pulley 7. The two synchronous pulleys 7 are connected by a synchronous belt. To ensure stable transmission, a synchronous belt tensioning mechanism 19 is also provided on the transmission path of the synchronous belt. The synchronous belt tensioning mechanism 19 is fixedly connected to the machine body mounting plate 1 and abuts against the outer periphery of the synchronous belt. Its function is to provide a constant tension force for the synchronous belt and ensure the accuracy of power transmission.

[0027] Meanwhile, to assist the reset action of the release plate 12, a release spring 4 is connected between the release plate 12 and the mounting plate 1 of the body. The two ends of the release spring 4 are hooked to the corresponding positions of the release plate 12 and the mounting plate 1 of the body, and its elastic force direction is opposite to the driving direction of the release cylinder 18, ensuring that the release plate 12 can be quickly reset after the release action is completed.

[0028] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, please refer to Figure 1To improve the stability of equipment operation and absorb vibration, the bottom of the mounting plate 1 is fixedly connected with the body anti-vibration adhesive 3.

[0029] As another preferred embodiment, please refer to Figure 1 and Figure 3 To provide protection for the internal functional components, a front side plate 6 and a rear side plate 20 are fixedly connected to both sides of the mounting plate 1, and an upper cover plate 15 covers the top of the mounting plate 1. A front cover 8 is installed on the outer surface of the front side plate 6, and a rear cover 21 is installed on the outer surface of the rear side plate 20.

[0030] As another preferred embodiment, please refer to Figure 2 An electrical box 16 is also fixedly installed on the mounting plate 1 of the machine body, and an electrical box cover 17 is provided on the outside of the electrical box 16.

[0031] As another preferred embodiment, please refer to Figure 1 The feeding device 14 is provided on the feeding side of the lower feeding roller 10 and the upper feeding roller 11, and the discharge side plate 2 is provided on the discharge side of the lower feeding roller 10 and the upper feeding roller 11. A pressure gauge 13 is also installed on the machine body mounting plate 1.

[0032] The working principle of this novel servo feeder is as follows: When the equipment is running, the servo motor 5 outputs power, which is transmitted precisely to the lower feeding roller 10 through the synchronous pulley 7 and the synchronous belt, and then through the tensioning mechanism 19 of the synchronous belt, causing it to rotate. The upper feeding roller 11 is paired with the lower feeding roller 10 to clamp the material together. The material enters from the feeding device 14 and is stably conveyed forward under the drive of the lower feeding roller 10 and the pressure of the upper feeding roller 11, and is finally discharged from the discharge side plate 2.

[0033] When material needs to be released, the release cylinder 18 is activated. The output end of the release cylinder 18 is hinged to the release plate 12. The action of the release cylinder 18 drives the release plate 12 to rotate around the release shaft 9, which is horizontally fixed on the machine body mounting plate 1. Since the upper feeding roller 11 is rotatably mounted on the release plate 12, the rotation of the release plate 12 will drive the upper feeding roller 11 to be lifted as a whole, so that it is separated from the material, thereby releasing the clamping force on the material. When the release action is completed, the release cylinder 18 is reset. At the same time, the release spring 4 connected between the release plate 12 and the machine body mounting plate 1 assists the release plate 12 to rotate in the opposite direction around the release shaft 9, driving the upper feeding roller 11 to quickly descend and return to the working position of clamping the material.

[0034] Throughout the entire operation, the mounting plate 1 serves as the base for all components. The anti-vibration rubber 3 at its bottom absorbs operational vibrations. The front side plate 6, rear side plate 20, front cover 8, rear cover 21, and upper cover 15 together form a protective outer shell. The electrical box 16 and its cover 17 protect the internal electrical control system. The pressure gauge 13 monitors the working air pressure of the release cylinder 18 in real time. Through the release cylinder 18, release plate 12, and release shaft 9, this directly driven release mechanism, combined with the rapid reset of the release spring 4, enables the rapid lifting and reset of the feeding roller 11. It features fast response and a stable and reliable structure.

[0035] 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.
