Description

Technical Field

[0001] This utility model relates to the field of protection and control technology for automated equipment, and in particular to a protection device based on photoelectric sensing. Background Technology

[0002] With the rapid development of the new energy battery manufacturing industry, roll-to-roll materials are widely used on production lines, especially in the handling and processing of continuous materials such as electrodes and separators. Automated feeding, unloading, and pushing of roll materials have become key processes. To improve production efficiency, many production lines have adopted automated pushing devices to transfer roll materials from one station to the next.

[0003] In existing technologies, feeding mechanisms typically include a feeding slider, a guide rail, a cylinder, and several limiting structures, used to push the coiled material along the material axis. However, in actual use, especially in automated handling scenarios in new energy battery manufacturing plants, operators often forget to activate the limiting cylinders used to hold the coiled material, causing the coiled material to jump, deviate from the guide rail, or even detach from the material axis during the feeding process. This not only causes equipment jamming or malfunctions but may also damage the coiled material itself, seriously affecting the stability of the production line and the yield of finished products.

[0004] Furthermore, most existing devices rely on manual observation or timed control to trigger actions, lacking an intelligent sensing mechanism that links with the actual material status. They cannot automatically determine whether the roll has been effectively fixed before the pushing action occurs, resulting in problems such as untimely response, poor safety, and high error rate. Utility Model Content

[0005] The purpose of this invention is to provide a protective device based on photoelectric sensing to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a photoelectric sensing-based protective device, including a buffer block, a pusher slider, a linear guide rail, a photoelectric sensing unit, a control unit, a bearing, a cylinder piston rod, a guide rail base plate, and a material shaft. The linear guide rail is arranged horizontally on both sides of the material shaft and is fixedly installed on the guide rail base plate by bolts. The pusher slider can slide along the axial direction of the linear guide rail. The buffer block is arranged above the front end of the guide rail base plate and at the lower end of the material shaft to absorb the impact force of the rolled material during the end stroke of the pusher slider. The bearing includes three sets of high-precision bearings, respectively arranged on the left and right sides of the material shaft and in its vertical direction, forming a multi-point support structure. The cylinder piston rod is arranged above the material shaft to limit and hold the rolled material under the control of the control unit. The photoelectric sensing unit is electrically connected to the control unit to detect the pushing state and control the operation of the device.

[0007] According to the above technical solution, one set of the bearings is arranged in a direction perpendicular to the horizontal axis of the material shaft, and the other two sets are located on the left and right sides of the material shaft, respectively, and are symmetrically arranged with the center line of the material shaft as the axis of symmetry.

[0008] According to the above technical solution, the cylinder piston rod has three rods, which are respectively located at the rear end above the material shaft, and at approximately 1 / 2 and 1 / 3 of the length of the guide rail base plate from its front end.

[0009] According to the above technical solution, the photoelectric sensing unit includes multiple photoelectric sensors for detecting the position of the rolled material on the material shaft.

[0010] According to the above technical solution, the guide rail base plate is provided with through holes and threaded holes, and the linear guide rail is connected to the threaded holes by bolts in sequence through the through holes.

[0011] According to the above technical solution, the pusher slider is embedded on the linear guide rail and matches the outer contour of the coil.

[0012] According to the above technical solution, the device is installed on an overall mechanical structure based on the material shaft and is used for the automatic handling process of coil material in the new energy battery manufacturing production line.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] 1. Improve the stability and safety of coil material handling: By setting up multi-point distributed bearings and cylinder piston rods, the movement of the coil material on the material shaft is supported and limited, effectively preventing the coil material from jumping, tilting or deviating from the track during the pushing process;

[0015] 2. Achieve intelligent control and precise linkage: The photoelectric sensing unit and the control unit work together to monitor the running status of the pusher slider in real time and output control commands to achieve coordinated control of the pusher action and the protective mechanism, avoiding accidental push or damage caused by operational negligence.

[0016] 3. Effectively avoids situations where limit switches are missed manually: It is especially suitable for automatic roll material handling scenarios in new energy battery manufacturing plants, solving problems such as roll material deviation, jamming, and even equipment damage caused by manual forgetting to activate the limit cylinder;

[0017] 4. Buffer and anti-collision structure improves device life: The buffer block set at the front end can absorb the impact force at the end of the pusher, playing a good role in shock absorption and damage protection, and extending the service life of the device. Attached Figure Description

[0024] 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.

[0025] Example:

[0026] The photoelectric sensing-based protective device includes a buffer block 1, a pusher slider 2, a linear guide rail 3, a photoelectric sensing unit 4, a control unit 5, a bearing 6, a cylinder piston rod 7, a guide rail base plate 8, and a material shaft 9. The entire device is installed on a mechanical structure based on the material shaft 9. The linear guide rail 3 is arranged horizontally on both sides of the material shaft 9. Its front end is bolted through the through holes on the guide rail base plate 8 and fastened to the threaded holes on the base plate 8, thereby achieving a high-strength and stable fixation between the guide rail and the base plate, ensuring that the pusher slider 2 will not deviate or shake due to loose guide rail during operation.

[0027] The buffer block 1 is fixedly installed above the front end of the guide rail base plate 8 and at the bottom end of the material shaft 9. It is used to absorb the impact force during the material roll collision when the pusher slider 2 is in the end stroke, and plays the role of shock absorption and damage protection, thereby improving the service life and stability of the device. The pusher slider 2 is embedded in the linear guide rail 3 and can slide linearly along the axial direction of the guide rail.

[0028] The load-bearing bearing 6 consists of three sets of high-precision cylindrical roller bearings, providing excellent load-bearing capacity and guiding performance. One set of bearings is positioned along the horizontal axis perpendicular to the material shaft 9, while the other two sets are distributed on the left and right sides of the material shaft 9, symmetrically arranged with the center line of the material shaft 9 as the axis of symmetry, forming a stable multi-point support structure. These three sets of bearings work together to provide uniform support during the material pusher's movement along the material shaft 9, effectively improving stability and positioning accuracy, and preventing swaying and jamming during movement.

[0029] Three cylinder piston rods 7 are provided, respectively located at the rear end above the material shaft 9, and at approximately 1 / 2 and 1 / 3 of the length of the guide rail base plate 8 from its front end. When there is rolled material on the material shaft 9, according to the command of the control unit 5, the cylinder piston rods 7 are driven by the cylinder to form a limiting support structure, which presses and limits the rolled material to prevent it from jumping or derailing during the movement and pushing of the pusher slider 2.

[0030] The control unit 5 is connected to the photoelectric sensing unit 4, the electric cylinder system and other electronic control devices. It is used to receive sensing signals, make logical judgments and output control commands to achieve precise control of the pushing action and intelligent operation of the whole device.

[0031] This device combines photoelectric sensing and automatic control to achieve real-time monitoring and protective control of the material pushing action. Its specific workflow is as follows:

[0032] When the equipment enters normal operation, the control unit 5 first performs an initial scan of each photoelectric sensing unit 4 to ensure that all sensors are in effective working condition. Afterward, the photoelectric sensing unit 4 continuously monitors the position or passage status of the rolled material in the material shaft 9 area. Once it detects that rolled material or external foreign objects have entered the rolled material area, it feeds back the position signal to the control unit 5 through a detection signal.

[0033] When a roll of material is detected on the material shaft 9, the control unit 5 first controls the cylinder piston rod 7 at the corresponding position to extend it from the initial retracted state and limit the roll of material to prevent it from jumping, slipping or falling during subsequent movement, and to ensure that it is stably stressed in the horizontal guide rail surface.

[0034] In addition, when the coil enters the feed shaft 9, its running posture is supported by three sets of bearings 6, ensuring that the coil slides stably on the feed shaft 9 without swaying and can accurately reach the front end position. When the front end stroke reaches the limit, the coil contacts the buffer block 1 through 9, and the buffer block 1 absorbs the remaining impact force, playing a role in terminal buffering and protection.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
