Description

Technical Field

[0001] This invention relates to the field of curing and feeding equipment technology, and in particular to an automatic rotary curing device. Background Technology

[0002] The main body of the workpiece is a cylindrical structure, and its outer surface is coated with a liquid adhesive. After coating, this type of workpiece requires a heat curing process to ensure the adhesive fully cures and achieves specific performance indicators. To ensure a uniform adhesive layer after curing and avoid localized adhesive buildup, the workpiece must be continuously rotated during the curing process to guarantee consistent adhesive distribution and a uniform film layer.

[0003] Currently, the movement of workpieces into and out of the curing oven relies on manual material transfer by operators, resulting in a large amount of repetitive manual labor and low material flow efficiency. To improve automation, the original plan was to use a logistics cart to transport workpieces into the oven. However, even with robots or other automated mechanisms transferring workpieces from the external rack to a dedicated rack inside the oven, efficiency bottlenecks remain. Therefore, the idea is to directly transport the entire external rack carrying the workpieces into the curing oven via a logistics cart. However, this method requires further solutions to the power transmission and docking issues between the curing oven and the rack. This application addresses these issues. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing an automatic rotary curing device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an automatic rotary curing device, comprising: A curing oven, wherein positioning bases are provided on the two inner side walls of the curing oven, and a material inlet is provided on one side of the curing oven, and a rotary motor assembly mechanism is provided on the other side of the curing oven; The material rack corresponds to the material inlet of the curing oven; The rack is equipped with a support mechanism for placing the workpiece to be cured; The material rack is also provided with a positioning limiting mechanism corresponding to the positioning base; The material rack is also equipped with a docking mechanism and a transmission mechanism for docking with the rotary motor assembly mechanism; After the material rack enters the curing oven through the inlet, it can be connected to the rotary motor assembly mechanism through the docking hole. The transmission mechanism drives the various supporting mechanisms on the material rack to operate synchronously, so as to rotate and cure the workpiece to be cured.

[0006] Furthermore, the material rack is a rectangular frame made of metal, and the bottom of the material rack is equipped with casters. The material rack is driven by an AGV trolley and transported to the curing oven.

[0007] Furthermore, the supporting mechanism includes multiple sets of support wheels A and support wheels B symmetrically arranged on the material rack along the width direction of the curing oven; Each set of support wheels B is provided with a chain drive mechanism between it and the adjacent support wheel B.

[0008] Furthermore, the limiting mechanism includes left and right limiting blocks and front and rear limiting blocks; The positioning base is provided with front and rear limiting V-blocks and left and right limiting V-blocks; The positioning base is liftably mounted on both sides of the curing oven. When the material rack moves into the curing oven, the positioning base is raised so that the front and rear limiting V-blocks and the left and right limiting V-blocks mounted on it engage with the front and rear limiting blocks and the left and right limiting blocks respectively, thereby achieving the positioning and fixing of the material rack.

[0009] Furthermore, the rotary motor assembly includes a support base, and a slider, a slide rail, and a servo motor are provided on the top of the support base. The servo motor can move relative to the support base. The rotary motor assembly mechanism also includes a pneumatic rod, a pneumatic rod pusher, and a connecting block. The pneumatic rod is located at the position corresponding to the slider and the slide rail, and its operation is used to push the servo motor to move toward the material rack. The servo motor output end is provided with a motor docking mechanism, and the servo motor is connected to the docking mechanism through the motor docking mechanism.

[0010] Furthermore, the motor docking mechanism includes a transmission rod A, a pin, a spring, a docking disc, and a transmission rod B; The transmission rod A is hollow inside, the transmission rod B is sleeved inside the transmission rod A, the surface of the transmission rod B is provided with a sliding groove, the pin is set on the inner wall of the transmission rod A and extends into the sliding groove and can move relative to it along the axial direction; The docking disk is disposed at the end of transmission rod B; The spring is positioned between the transmission rod A and the docking disk to provide elastic compensation in the axial direction.

[0011] Furthermore, the docking disc is provided with multiple sets of docking bosses, and the ends of the docking bosses are tapered. The docking structure has docking holes corresponding to the docking bosses.

[0012] The beneficial effects of this invention are reflected in: This invention features a compact and reasonable structural design, a simple and efficient operation process, and can achieve fully unmanned operation. It can automatically complete docking and power transmission, and monitor the workpiece rotation status and system operating parameters in real time, significantly improving production efficiency and process consistency, and greatly enhancing the automation level of workpiece processing.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-5 This invention discloses an automatic rotary curing device, comprising: Curing oven 1, with positioning bases 3 on the two inner side walls of the curing oven 1, a material inlet on one side of the curing oven 1, and a rotary motor assembly mechanism 4 on the other side of the curing oven 1. It should be noted that the curing oven 1 is equipped with auxiliary curing and other related structures. Since this technology is a common technical means in the prior art, it is not described in detail in this application. Material rack 2, which corresponds to the material inlet of curing oven 1, specifically, as shown in... Figure 2 As shown, the material rack 2 is a rectangular frame made of metal. The bottom of the material rack 2 is provided with a movable frame, and the bottom of the movable frame is provided with movable wheels. The material rack 2 is driven and transported to the curing oven 1 by an AGV trolley (not shown in the figure). The AGV trolley is used to pull and transport the material rack 2 so as to transfer the material rack 2 between the curing oven 1 and the designated storage location in an orderly and efficient manner. The material rack 2 is provided with a support mechanism for placing the workpiece to be cured; The material rack 2 is also provided with a positioning limiting mechanism corresponding to the positioning base 3, wherein the positioning limiting mechanism is used to precisely limit the position of the material rack 2 inside the curing oven 1; The material rack 2 is also provided with a docking mechanism 24 for docking with the rotary motor assembly mechanism 4 and a transmission mechanism; After the material rack 2 enters the curing oven 1 through the inlet, it can be connected to the rotary motor assembly mechanism 4 through the docking hole. The transmission mechanism drives the various supporting mechanisms on the material rack 2 to run synchronously, so as to drive the workpiece to be cured to rotate and cure.

[0017] With the above-mentioned structural configuration, in use, the material rack 2 with the workpiece to be cured can be transferred to the inside of the curing oven 1 by an AGV trolley. Then, the positioning base 3 contacts the bottom of the material rack 2, thereby locking the material rack 2. Finally, the rotary motor assembly mechanism 4 docks with the docking mechanism 24 on the material rack 2. The rotary motor assembly mechanism 4 runs and drives each workpiece to be cured to rotate through the transmission mechanism on the material rack 2.

[0018] In this application, it is readily apparent that the supporting mechanism includes multiple sets of support wheels A21 and support wheels B22 symmetrically arranged on the material rack 2 along the width direction of the curing oven 1; Each set of support wheels B22 is provided with a chain drive mechanism 23 between it and the adjacent support wheel B22. The chain drive mechanism 23 is connected to the transmission mechanism to realize the synchronous operation of each support wheel B22. The support wheel B22 and support wheel A21 are composed of two sets of bearing wheels arranged in parallel, and a sprocket is provided at the other end of the bearing wheel.

[0019] It should be noted that the ends of the workpiece to be cured in this application are usually cylindrical structures, and the two ends of the workpiece to be cured are respectively mounted between two sets of bearing wheels. The two sets of bearing wheels of the support wheel B22 can drive the workpiece to be cured to rotate at a corresponding speed under the transmission of the chain drive mechanism 23 and the transmission mechanism. What needs to be explained in detail is, for example Figure 2 As shown, a transmission chain is provided between the two sets of bearing wheels, and a transmission chain is also provided between adjacent support wheels B22. Each sprocket serves as both the driven wheel of the previous sprocket and the driving wheel of the next sprocket, thereby enabling a single motor to drive all support wheels B22 to rotate synchronously.

[0020] In this application, the limiting mechanism includes left and right limiting blocks 26 and front and rear limiting blocks 27; The positioning base 3 is provided with front and rear limiting V-blocks 31 and left and right limiting V-blocks 32; The positioning base 3 is vertically and flexibly mounted on both sides of the curing oven 1. When the material rack 2 moves into the curing oven 1, the positioning base 3 is raised so that the front and rear limiting V-blocks 31 and the left and right limiting V-blocks 32 mounted on it engage with the front and rear limiting blocks 27 and the left and right limiting blocks 26 respectively, thereby achieving the positioning and fixing of the material rack 2.

[0021] In this application, the front and rear limiting V-blocks 31 and the left and right limiting V-blocks 32 are two sets of positioning blocks arranged perpendicularly to each other, and a V-groove is provided in the center of the positioning block to cooperate with the front and rear limiting blocks 27 and the left and right limiting blocks 26 to achieve positioning of the material rack 2.

[0022] It is easy to imagine that lifting and extension mechanisms corresponding to positioning base 3 are provided on both sides of curing oven 1. These mechanisms can position material rack 2 during the curing process of curing oven 1. At the same time, they can retract and avoid obstructing the material rack 2 during its entry and exit from curing oven 1, so as to avoid affecting the normal conveying process of material rack 2.

[0023] In this application, the rotary motor assembly mechanism 4 includes a support base 48, and a slider 43, a slide rail 44, and a servo motor 41 are provided on the top of the support base 48. The servo motor 41 can move relative to the support base 48. The rotary motor assembly mechanism 4 also includes a pneumatic rod 45, a pneumatic rod pusher 46, and a connecting block 47. The pneumatic rod 45 is located at the position corresponding to the slider 43 and the slide rail 44, and its operation is used to push the servo motor 41 to move toward the material rack 2. The servo motor 41 is provided with a motor docking mechanism 42 at its output end, and the servo motor 41 is connected to the docking mechanism 24 through the motor docking mechanism 42.

[0024] It should be noted that the motor docking mechanism 42 includes a transmission rod A421, a pin 422, a spring 423, a docking disc, and a transmission rod B425; The transmission rod A421 is hollow inside, the transmission rod B425 is sleeved inside the transmission rod A421, the surface of the transmission rod B425 is provided with a sliding groove, and the pin 422 is provided on the inner wall of the transmission rod A421 and extends into the sliding groove and can move relative to it along the axial direction. The docking disc is located at the end of the transmission rod B425; The spring 423 is disposed between the transmission rod A421 and the docking disk to provide elastic compensation in the axial direction.

[0025] Furthermore, the docking disc is provided with multiple sets of docking bosses 424, and the ends of the docking bosses 424 are tapered. The docking structure 24 is provided with docking holes 25 corresponding to the docking boss 424.

[0026] With the above structural arrangement, when the docking boss 424 initially contacts the disc surface of the material rack docking mechanism 24, the spring 423 is compressed and deformed under the action of axial force, and the transmission rod B425 retracts (as shown). Figure 5 (State 1); At this time, the servo motor 41 starts and rotates, driving the motor docking mechanism 42 to rotate, while the material rack docking mechanism 24 does not move accordingly. During the continuous rotation and adjustment process, once the docking boss 424 approaches the axis of the docking hole 25, the spring 423 pushes the transmission rod B425 back to move towards the material rack side (e.g., Figure 5 (State 2), so that the docking boss 424 is embedded in the docking hole 25, and finally the reliable docking and power transmission of the transmission mechanism are realized.

[0027] During operation, the device monitors the running status of the servo motor 41 in real time and continuously detects its speed and working condition. Once an abnormal condition such as stopping or abnormal speed is detected, an alarm signal is immediately triggered to achieve real-time feedback of equipment status and fault diagnosis, ensuring stable operation of the curing process and product quality.

[0028] The workflow of the automatic rotary curing apparatus described in this application includes the following steps: S1. The logistics trolley transports the material rack 2 loaded with workpieces into the curing oven cavity, and the material rack 2 is precisely positioned and fixed by the positioning base 3; S2. After the material rack 2 is fixed, the curing oven automatically closes the oven door, and the rotary motor assembly mechanism 4 automatically docks with the material rack 2. During the process, the system monitors the operating status of the servo motor 41 in real time. S3. After docking is completed, the curing oven will automatically start the heating system according to the preset process program and perform heating and curing according to the set temperature curve; S4. After the curing process is completed, heating stops, the rotary motor assembly mechanism 4 retracts and separates from the material rack 2, and then the furnace door opens automatically; S5. The logistics trolley transports the solidified material rack 2 out of the furnace cavity.

[0029] This invention features a compact and rational structural design, a simple and efficient operation process, and enables fully unmanned operation. It automatically completes docking and power transmission, and monitors the workpiece rotation status and system operating parameters in real time, significantly improving production efficiency and process consistency, and greatly enhancing the automation level of workpiece processing. This device is particularly suitable for industrial curing applications with high requirements for positioning accuracy, transmission stability, and process automation.

If the specific posture changes, the directional indicators will also change accordingly.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
