This clamping mechanism, by setting up an adjustment mechanism, a limiting mechanism, an industrial camera, and a controller, uses a pressure sensor and spring linkage design in the limiting mechanism to monitor the clamping force in real time and feed it back to the controller. Combined with a silicone buffer layer on the surface of the clamping plate, dynamic control of the clamping force is achieved, effectively preventing damage to the insulation layer of the electric heating tube body caused by excessive clamping force. The industrial camera covers the surface of the worktable, acquiring geometric feature images of the electric heating tube body.

With the help of the sliding groove and slider guide structure on the worktable, the distance between the two sets of limiting mechanisms can be adjusted synchronously to accommodate electric heating tube bodies of different diameters. When switching electric heating tube body models, only the new electric heating tube body needs to be placed on the worktable.

Description

Technical Field

[0001] This application relates to the field of electric heating tube technology, specifically a clamping mechanism for encapsulating electric heating tubes. Background Technology

[0002] A tubular heating element (or heating tube for short) is an electrical component specifically designed to convert electrical energy into heat energy. It consists of a metal tube as its outer shell (including stainless steel and copper tubes), with spiral heating alloy wires (nickel-chromium or iron-chromium alloy) evenly distributed along the central axis inside the tube. The gaps are filled with compacted magnesium oxide sand, which has good insulation and thermal conductivity. Both ends of the tube are sealed with silicone. This metal-clad heating element can heat air, metal molds, and various liquids. Common heating elements include finned heating elements, Teflon heating elements, and quartz heating elements. Due to their low price, ease of use, convenient installation, and lack of pollution, they are widely used in various heating applications.

[0003] Currently, manual or semi-automatic clamping devices are commonly used in the packaging process of electric heating tubes. These devices have the following technical drawbacks: traditional mechanical clamping plates lack pressure feedback, which can easily damage the insulation layer on the surface of the electric heating tube due to excessive clamping force; and different specifications of electric heating tubes require frequent adjustment of clamping parameters, which affects production efficiency. Therefore, a clamping mechanism for packaging electric heating tubes is provided. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides a clamping mechanism for encapsulating electric heating tubes, which avoids damage to the insulation layer on the surface of the electric heating tube due to excessive clamping force, and facilitates automatic adjustment of the clamping mechanism according to different specifications of electric heating tubes.

[0006] To achieve the above objectives, this application provides the following technical solution: a clamping mechanism for encapsulating an electric heating tube, comprising a worktable, an adjustment mechanism, and a limiting mechanism. The adjustment mechanism is disposed at the front end of the worktable. Two sets of limiting mechanisms are symmetrically arranged on the upper ends of the worktable and the adjustment mechanism. An industrial camera is disposed on the upper end of the adjustment mechanism. A controller is disposed on the front side of the adjustment mechanism. An electric heating tube body is disposed on the upper surface of the worktable. The electric heating tube body is disposed between the two sets of limiting mechanisms. A dual-axis motor is disposed inside the adjustment mechanism. A pressure sensor is disposed inside the limiting mechanism. A graphics processor is disposed inside the controller. The dual-axis motor, the pressure sensor, and the industrial camera are all electrically connected to the controller.

[0007] The above solution, through the setting of an adjustment mechanism, a limiting mechanism, an industrial camera, and a controller, uses a pressure sensor and spring linkage design in the limiting mechanism to monitor the clamping force in real time and feed it back to the controller. Combined with the silicone buffer layer on the surface of the clamping plate, dynamic control of the clamping force is achieved, effectively avoiding damage to the insulation layer of the heating tube body caused by excessive clamping force. The industrial camera covers the surface of the worktable and captures geometric feature images of the heating tube body. Then, the controller controls the dual-axis motor in the adjustment mechanism to drive the threaded column and connecting rod. With the help of the sliding groove and slider guide structure on the worktable, the distance between the two sets of limiting mechanisms can be adjusted simultaneously to adapt to heating tube bodies of different diameters. When switching heating tube body models, simply place the new heating tube body on the worktable, and the industrial camera will automatically trigger recognition. The controller will synchronously call the corresponding parameters to drive the adjustment mechanism to complete the clamping preparation. No manual disassembly or manual adjustment of the fixture is required throughout the process.

[0008] Furthermore, the adjustment mechanism includes a housing, which is fixedly connected to the front side of the worktable. The dual-axis motor is fixedly connected inside the housing. Both ends of the output shaft of the dual-axis motor are fixedly connected to threaded columns. The ends of the two sets of threaded columns away from the dual-axis motor are fixedly connected to rotating shafts. Bearings are installed on both the left and right sides inside the housing. The ends of the two sets of rotating shafts away from the dual-axis motor are installed inside the two sets of bearings. Threaded caps are threaded onto the surfaces of the two sets of threaded columns. Connecting rods are fixedly connected to the surfaces of the two sets of threaded caps. A limit groove is formed on the upper surface of the housing, and the connecting rod passes through the limit groove. The industrial camera is fixedly connected to the upper surface of the housing, and the controller is fixedly connected to the front side of the housing.

[0009] The above scheme drives the threaded columns on both sides to rotate synchronously. Through the transmission between the threaded cap and the connecting rod, it ensures that the two sets of limit mechanisms move symmetrically, eliminating the skew error caused by unilateral drive.

[0010] Furthermore, the limiting mechanism includes movable plates, with two sets of movable plates fixedly connected to the upper ends of two sets of connecting rods. Each movable plate has a placement groove inside, and the pressure sensor is fixedly connected inside the placement groove. Slide rods are movably connected to opposite sides of both sets of movable plates, and these slide rods are movably connected inside the placement grooves to cooperate with the pressure sensor. A clamping plate is fixedly connected to the end of the slide rod away from the pressure sensor, and a spring is sleeved on the surface of the end of the slide rod away from the pressure sensor. One end of the spring is fixedly connected to the side of the movable plate, and the other end of the spring is fixedly connected to the side of the clamping plate. The heating element body is positioned between the two sets of clamping plates.

[0011] Through the above scheme, the slide bar is linked with the pressure sensor to provide real-time feedback on the contact pressure of the clamping plate on the heating element body. When the pressure exceeds the limit, the controller immediately triggers the motor retraction program, reducing the breakage rate.

[0012] Furthermore, a slider is fixedly connected to the lower end of the movable plate, and a ball is rotatably connected to the lower end of the slider. A groove is provided on the upper surface of the worktable, and the ball is movably connected inside the groove.

[0013] With the above solution, the balls roll and are guided within the groove, reducing the coefficient of friction and decreasing the resistance to movement of the movable plate, thus ensuring a smooth and uninterrupted adjustment process.

[0014] Furthermore, a base plate is provided at the lower end of the workbench, and an electric push rod is fixedly connected to the upper surface of the base plate. The upper end of the electric push rod is fixedly connected to the lower surface of the workbench, and the electric push rod is electrically connected to the controller.

[0015] The above solution enables the electric actuator to drive the worktable to rise and fall, making it compatible with packaging equipment interfaces of different heights and improving the equipment's versatility.

[0016] Furthermore, the base plate is internally threaded with bolts, and there are four sets of bolts arranged in a rectangular shape inside the base plate.

[0017] The above scheme uses four sets of bolts arranged in a rectangular pattern to lock the base plate, effectively suppressing the impact of high-frequency vibration on clamping accuracy.

[0018] Furthermore, the industrial camera's illumination angle covers the surface of the worktable, and the worktable surface is provided with limit blocks.

[0019] With the above solution, the industrial camera covers the entire surface of the workbench, and combined with the reference coordinate positioning of the limit block, the position recognition accuracy of the heating tube body is high, eliminating missed detections or false detections.

[0020] Furthermore, the surface of the clamping plate is provided with a silicone buffer layer, and the surface of the silicone buffer layer is provided with anti-slip texture.

[0021] The above method allows the silicone layer to elastically conform to the curvature of the heating element body surface, compensating for the manufacturing tolerance of the workpiece diameter and ensuring a uniform distribution of clamping force.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This clamping mechanism for encapsulating electric heating tubes comprises an adjustment mechanism, a limiting mechanism, an industrial camera, and a controller. The limiting mechanism uses a pressure sensor linked to a spring to monitor the clamping force in real time and feed it back to the controller. Combined with a silicone buffer layer on the clamping plate surface, dynamic control of the clamping force is achieved, effectively preventing damage to the insulation layer of the electric heating tube due to excessive clamping force. The industrial camera covers the worktable surface, capturing geometric feature images of the electric heating tube. The controller then controls a dual-axis motor in the adjustment mechanism to drive the threaded column and connecting rod. In conjunction with the sliding groove and slider guide structure on the worktable, the distance between the two sets of limiting mechanisms can be adjusted synchronously to accommodate electric heating tubes of different diameters. When switching electric heating tube models, simply place the new electric heating tube on the worktable; the industrial camera automatically triggers recognition, and the controller synchronously calls the corresponding parameters to drive the adjustment mechanism to complete the clamping preparation. The entire process requires no manual disassembly or adjustment of the clamp. Attached Figure Description

The dual-axis motor 202, the pressure sensor 303, and the industrial camera 4 are all electrically connected to the controller 5. By setting the adjusting mechanism 2, the limiting mechanism 3, the industrial camera 4, and the controller 5, the pressure sensor 303 in the limiting mechanism 3 interacts with the spring. The spring 306 linkage design monitors the clamping force in real time and feeds it back to the controller 5. Combined with the silicone buffer layer on the surface of the clamping plate 305, the clamping force is dynamically adjusted, effectively avoiding damage to the insulation layer of the heating tube body 6 caused by excessive clamping force. The industrial camera 4 covers the surface of the workbench 1 and captures geometric feature images of the heating tube body 6. Then, the controller 5 controls the dual-axis motor 202 in the adjustment mechanism 2 to drive the threaded column 203 and the connecting rod 207. With the guide structure of the slide groove 8 and the slider 9 on the workbench 1, the distance between the two sets of limit mechanisms 3 can be adjusted synchronously to adapt to heating tube bodies 6 of different diameters. When switching the model of the heating tube body 6, simply place the new heating tube body 6 on the workbench 1, and the industrial camera 4 will automatically trigger recognition. The controller 5 will synchronously call the corresponding parameters to drive the adjustment mechanism 2 to complete the clamping preparation. No manual disassembly or manual adjustment of the fixture is required throughout the process.

[0033] Please see Figure 1 , Figure 4 and Figure 5The adjusting mechanism 2 includes a housing 201, which is fixedly connected to the front side of the worktable 1. A dual-axis motor 202 is fixedly connected inside the housing 201. Threaded posts 203 are fixedly connected to both ends of the output shaft of the dual-axis motor 202. Rotating shafts 204 are fixedly connected to the ends of the two sets of threaded posts 203 away from the dual-axis motor 202. Bearings 205 are installed on both the left and right sides inside the housing 201. The ends of the two sets of rotating shafts 204 away from the dual-axis motor 202 are installed inside the two sets of bearings 205. The two sets of threaded posts 204... The outer shell 201 has threaded caps 206 on each surface, and connecting rods 207 are fixedly connected to the surfaces of the two sets of threaded caps 206. A limiting groove 208 is formed on the upper surface of the outer shell 201, and the connecting rods 207 pass through the limiting groove 208. The industrial camera 4 is fixedly connected to the upper surface of the outer shell 201, and the controller 5 is fixedly connected to the front side of the outer shell 201. The limiting mechanism 3 includes a movable plate 301, and two sets of movable plates 301 are fixedly connected to the upper ends of the two sets of connecting rods 207. A placement groove 302 is formed inside the movable plate 301. The pressure sensor 303 is fixedly connected inside the placement slot 302. Slide rods 304 are movably connected to opposite sides of the two sets of movable plates 301, and the slide rods 304 are movably connected inside the placement slot 302 to cooperate with the pressure sensor 303. A clamping plate 305 is fixedly connected to the end of the slide rod 304 away from the pressure sensor 303. A spring 306 is sleeved on the surface of the end of the slide rod 304 away from the pressure sensor 303. One end of the spring 306 is fixedly connected to the side of the movable plate 301, and the other end of the spring 306 is fixedly connected to... The heating element body 6 is positioned between the two sets of clamping plates 305 and attached to the side of the clamping plate 305. The dual-axis motor 202 drives the threaded columns 203 on both sides to rotate synchronously. Through the transmission of the threaded cap 206 and the connecting rod 207, the two sets of limiting mechanisms 3 move symmetrically, eliminating the skew error caused by unilateral drive. The slide rod 304 is linked with the pressure sensor 303 to provide real-time feedback on the contact pressure of the clamping plate 305 on the heating element body 6. When the pressure exceeds the limit, the controller 5 immediately triggers the motor retraction program, reducing the breakage rate.

[0034] Please see Figure 1 , Figure 2 and Figure 3A slider 9 is fixedly connected to the lower end of the movable plate 301, and a ball bearing 10 is rotatably connected to the lower end of the slider 9. A groove 8 is provided on the upper surface of the worktable 1, and the ball bearing 10 is movably connected inside the groove 8. A base plate 11 is provided at the lower end of the worktable 1, and an electric push rod 12 is fixedly connected to the upper surface of the base plate 11. The upper end of the electric push rod 12 is fixedly connected to the lower surface of the worktable 1, and the electric push rod 12 is electrically connected to the controller 5. Bolts 13 are threaded inside the base plate 11. There are four sets of bolts 13, which are arranged in a rectangle inside the base plate 11. The ball bearing 10 rolls and is guided in the groove 8, which reduces the coefficient of friction and reduces the moving resistance of the movable plate 301, ensuring a smooth adjustment process without jamming. The electric push rod 12 drives the worktable 1 to rise and fall, which is compatible with the interfaces of packaging equipment of different heights, improving the versatility of the equipment. The four sets of bolts 13 are arranged in a rectangle to lock the base plate 11, effectively suppressing the influence of high-frequency vibration on the clamping accuracy.

[0035] Please see Figure 1 , Figure 2 and Figure 3 The industrial camera 4 covers the surface of the worktable 1 with an illumination angle. The worktable 1 is equipped with a limit block 7. The clamping plate 305 is provided with a silicone buffer layer, and the surface of the silicone buffer layer is provided with anti-slip texture. The industrial camera 4 covers the entire surface of the worktable 1. Combined with the reference coordinate positioning of the limit block 7, the position recognition accuracy of the heating tube body 6 is high, eliminating missed detections or false detections. The silicone layer elastically fits the surface curvature of the heating tube body 6 to compensate for the manufacturing tolerance of the workpiece diameter and ensure uniform distribution of clamping force.

[0036] In this embodiment, by setting up an adjustment mechanism 2, a limiting mechanism 3, an industrial camera 4, and a controller 5, the pressure sensor 303 in the limiting mechanism 3 is linked with the spring 306 to monitor the clamping force in real time and feed it back to the controller 5. Combined with the silicone buffer layer on the surface of the clamping plate 305, the clamping force can be dynamically adjusted, effectively avoiding damage to the insulation layer of the electric heating tube body 6 caused by excessive clamping force. The industrial camera 4 covers the surface of the workbench 1 and collects geometric feature images of the electric heating tube body 6. Then, the controller 5 controls the dual-axis motor 202 in the adjustment mechanism 2 to drive the threaded column 203 and the connecting rod 207. With the guide structure of the slide groove 8 and the slider 9 on the workbench 1, the distance between the two sets of limiting mechanisms 3 can be adjusted synchronously to adapt to electric heating tube bodies 6 of different diameters. When switching the model of the electric heating tube body 6, it is only necessary to place the new electric heating tube body 6 on the workbench 1. The industrial camera 4 will automatically trigger recognition, and the controller 5 will synchronously call the corresponding parameters to drive the adjustment mechanism 2 to complete the clamping preparation. There is no need for manual disassembly or manual adjustment of the fixture throughout the process.

[0037] The working principle of the above embodiment is as follows: The heating element body 6 is placed on the surface of the workbench 1 and initially positioned by the limiting block 7. The industrial camera 4 acquires images of the heating element body 6 by covering the entire surface of the workbench 1 with an illumination angle. The graphics processor in the controller 5 analyzes the diameter, length and position offset of the heating element body 6 in real time and generates clamping parameter instructions. The controller 5 drives the dual-axis motor 202 in the adjustment mechanism 2 to start according to the recognition results. The output shaft of the dual-axis motor 202 drives the two sets of threaded columns 203 to rotate synchronously. Through the transmission of the threaded cap 206 and the connecting rod 207, the two sets of movable plates 301 are pushed to move in opposite directions or in the opposite direction along the ball bearings 10 in the slide groove 8, so that the spacing of the clamping plates 305 of the limiting mechanism 3 automatically matches the diameter of the heating element body 6 and completes adaptive adjustment. When the clamping plate 305 contacts the heating element body 6, the spring 306 is compressed and contracts, the slide rod 304 slides into the placement groove 302 and triggers the pressure sensor 303. The controller 5 receives pressure data in real time and dynamically adjusts the output torque of the dual-axis motor 202 based on a preset safety threshold. If the pressure exceeds the upper limit, the controller 5 controls the dual-axis motor 202 to reverse slightly and reduce the clamping force. If the pressure is insufficient, the motor torque is increased to further press the clamping plate 305 until a stable clamping state is achieved. During the encapsulation process, the controller 5 synchronously controls the electric push rod 12 on the base plate 11 to raise and lower the worktable 1 and adjust the height of the heating tube body 6 to adapt to different encapsulation equipment interfaces. The silicone buffer layer and anti-slip texture on the surface of the clamping plate 305 absorb vibration and prevent the heating tube body 6 from sliding during the clamping process. After encapsulation, the controller 5 controls the dual-axis motor 202 to reverse and drive the clamping plate 305 to reset to the initial position. At the same time, the controller saves the image data, pressure curve, and adjustment parameters collected by the industrial camera 4, forming a traceable process archive.
