Description

Technical Field

[0001] The utility model belongs to the technical field of continuous furnace transfer, in particular to a boat-feeding manipulator device for a vertical continuous furnace. Background Art

[0002] In modern manufacturing, continuous furnaces, as a key heat treatment equipment, are widely used in the processing and production of electronics, metals, ceramics, and other fields. Through continuous heating and cooling processes, continuous furnaces achieve efficient and stable production processes. To ensure the stable transportation of materials within the continuous furnace, a boat pusher robot has become an indispensable and important device. This boat pusher robot is an automated device responsible for pushing the material-loaded boat into the continuous furnace and ejecting it after processing. The operating accuracy and stability of this equipment are directly related to the quality and efficiency of the entire heat treatment process.

[0003] Most industrial furnace loading and unloading boats on the market use hydraulic push rods. While this method operates quickly, it cannot meet the process requirements of slow, steady boat pushing. Furthermore, due to its high speed, the hydraulic push rod method cannot immediately stop the boat feeding if an abnormality such as a boat jam occurs in the furnace. Utility Model Content

[0004] The purpose of the utility model is to provide a boat feeding robot device for a vertical continuous furnace to solve the problems raised in the above-mentioned prior art.

[0005] Provided is a boat feeding manipulator device for a vertical continuous furnace, comprising:

[0006] A mounting base, comprising a front fixing seat and a rear fixing seat;

[0007] A manipulator device includes a boat pushing plate, a plurality of guide rods and a transmission plate, wherein the boat pushing plate is fixedly connected to the transmission plate through the plurality of guide rods, and the plurality of guide rods are respectively slidably connected to the front fixing seat;

[0008] The driving device includes a driving motor, a trapezoidal screw and a trapezoidal nut. The trapezoidal nut is threadedly connected to the trapezoidal screw. The trapezoidal screw is rotatably connected between the front fixing seat and the rear fixing seat. The driving motor is used to drive the trapezoidal screw to rotate. The trapezoidal nut is fixedly connected to the transmission plate.

[0009] Furthermore, the drive device further includes a transmission assembly, wherein the output shaft of the drive motor is connected to the trapezoidal lead screw via the transmission assembly. The torque of the drive motor is transmitted to the trapezoidal lead screw via the transmission assembly, thereby changing the output direction of the output shaft of the drive motor and making the arrangement of the drive motor more flexible.

[0010] Furthermore, the transmission assembly includes two synchronous wheels and a synchronous belt. The two synchronous wheels are fixedly connected to the trapezoidal lead screw and the output shaft of the drive motor, respectively, and the synchronous belt meshes with the two synchronous wheels. The synchronous belt meshes with the synchronous wheels through its teeth, preventing relative slippage during transmission, ensuring an accurate transmission ratio. This is suitable for applications requiring precise synchronization and can ensure that the trapezoidal lead screw stops quickly, immediately stopping the boat feed action.

[0011] Furthermore, two trapezoidal screws and two trapezoidal nuts are provided. The two trapezoidal screws are connected to the drive motor via a transmission assembly. The two trapezoidal nuts are respectively located on the corresponding trapezoidal screws and fixedly connected to the transmission plate. Transmission via two trapezoidal screws evenly distributes torque, improving the stability of the transmission structure. Furthermore, the transmission plate, fixed to the two trapezoidal nuts, does not rotate when restrained by the two trapezoidal screws, eliminating the need for additional restraining structures to guide the transmission plate's path.

[0012] Furthermore, the transmission assembly includes three synchronous wheels, a synchronous belt, and a steering wheel. A synchronous wheel is provided on each of the two trapezoidal screws and the output shaft of the drive motor. The synchronous belt, after passing around the steering wheel midway along its path, engages with each of the three synchronous wheels. The steering wheel can change the transmission direction of the synchronous belt. By engaging the three synchronous wheels with one synchronous belt, a single drive motor can drive the rotation of the two trapezoidal screws.

[0013] Furthermore, a linear bearing is provided between the guide rod and the front fixing seat, which can guide the guide rod to move forward, making the guide rod sliding more smoothly.

[0014] Furthermore, a plurality of cast iron wheels are provided at the bottom of the boat pushing plate, and the cast iron wheels are used to support the boat pushing plate and guide the movement of the boat pushing plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The boat-feeding manipulator provided in this application is driven by a drive mechanism formed by a drive motor and a lead screw assembly. A trapezoidal lead screw and a trapezoidal nut drive the manipulator, resulting in controllable speed, high precision, and smooth boat feeding. If an abnormality such as a boat jam occurs within the furnace, the manipulator immediately stops feeding the boat. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] However, there will be cases where unnecessary detailed descriptions are omitted.

[0027] Please refer to Figures 1-5 As shown, in the embodiment of the present utility model, a boat feeding manipulator device for a vertical continuous furnace includes a mounting base 1, a manipulator assembly 2, and a driving device 3. The mounting base 1 includes a front fixing seat 11 and a tail fixing seat 12. The manipulator assembly 2 includes a boat pushing plate 21, a plurality of guide rods 22, and a transmission plate 23. The boat pushing plate 21 is fixedly connected to the transmission plate 23 through a plurality of guide rods 22, and the plurality of guide rods 22 are respectively slidably connected to the front fixing seat 11. The driving device 3 includes a driving motor 31, a trapezoidal lead screw 32, and a trapezoidal nut 33. The trapezoidal nut 33 is threadedly connected to the trapezoidal lead screw 32. The trapezoidal lead screw 32 is rotatably connected between the front fixing seat 11 and the tail fixing seat 12. The driving motor 31 is used to drive the trapezoidal lead screw 32 to rotate, and the trapezoidal nut 33 is fixedly connected to the transmission plate 23.

[0028] Both ends of the trapezoidal lead screw 32 are respectively supported on the upper parts of the front fixing seat 11 and the tail fixing seat 12 and are rotatably connected. The end of the trapezoidal lead screw 32 close to the front fixing seat 11 is drivingly connected to the output shaft of the driving motor 31. When performing the boat pushing or retracting operation, the output shaft of the driving motor 31 drives the trapezoidal lead screw 32 to rotate. After the trapezoidal lead screw 32 rotates, it drives the trapezoidal nut 33 to move through screw engagement. The trapezoidal nut 33 drives the transmission plate 23 to move along the length direction of the trapezoidal lead screw 32. Since the transmission plate 23 is fixed to the boat pushing plate 21 through the guide rods 22, the transmission plate 23 can then push the boat pushing plate 21 to complete the boat pushing operation. During the process of the transmission plate 23 pushing the boat pushing plate 21 to move, the guide rods 22 limit their radial degrees of freedom through the front fixing seat 11, so that the guide rods 22 translate along a predetermined direction.

[0029] The driving device 3 further includes a transmission assembly 34. The output shaft of the driving motor 31 is drivingly connected to the trapezoidal lead screw 32 through the transmission assembly 34. After the torque output direction is changed by the transmission assembly 34, the driving motor 31 can be installed reversely, so that the center of gravity of the boat loading manipulator moves forward and approaches the front fixing seat 11, shortening the overall length of the boat loading manipulator.

[0030] In one embodiment, the transmission assembly 34 is composed of a gear set. The driving gear is arranged at the end of the output shaft of the driving motor 31, and the driven gear is arranged at the end of the trapezoidal lead screw 32. The torque of the driving motor 31 is transmitted to the trapezoidal lead screw 32 through the meshing of the driving gear and the driven gear. Although the gear set can maintain an accurate transmission ratio, the transmission distance of the gear set is limited by the transmission arm of the gear. Once the installation distance between the driving motor 31 and the trapezoidal lead screw 32 is too far or the transmission of multiple trapezoidal lead screws 32 needs to be satisfied simultaneously, it is difficult for the gear set to meet the long-distance transmission requirements.

[0031] In one embodiment, the transmission assembly 34 includes two synchronous pulleys 341 and a synchronous belt 342. The two synchronous pulleys 341 are respectively fixedly connected to the trapezoidal lead screw 32 and the output shaft of the driving motor 31, and the synchronous belt 342 is respectively meshed with the two synchronous pulleys 341. The synchronous pulleys 341 and the synchronous belt 342 can also maintain an accurate transmission ratio through meshing, and the length of the synchronous belt 342 can be freely arranged to meet the requirements of long-distance transmission.

[0032] In one embodiment, there are two trapezoidal lead screws 32 and two trapezoidal nuts 33. The two trapezoidal lead screws 32 are drivingly connected to the driving motor 31 through the transmission assembly 34. The two trapezoidal nuts 33 are respectively located on the corresponding trapezoidal lead screws 32 and fixedly connected to the transmission plate 23. The number of guide rods 22 is preferably two. The two guide rods 22 are respectively arranged on both sides of the boat loading manipulator, and the two trapezoidal lead screws 32 are respectively arranged close to the two guide rods 22 to improve the overall running stability of the boat loading manipulator, improve the running accuracy, and avoid the problem of boat jamming.

[0033] Further, the transmission assembly 34 includes three synchronous pulleys 341, a synchronous belt 342, and a steering pulley 343. The three synchronous pulleys 341 are respectively arranged on the two trapezoidal lead screws 32 and the output shaft of the driving motor 31. To ensure that the synchronous belt 342 has a certain meshing area on the three synchronous pulleys 341, the synchronous pulley 341 on the driving motor 31 and the two synchronous pulleys 341 on the two trapezoidal lead screws 32 are not in the same horizontal plane. In a specific case, the two trapezoidal lead screws 32 are located in the same horizontal plane and arranged in parallel, and the driving motor 31 is located at the bottom of the two trapezoidal lead screws 32. To increase the meshing area between the synchronous pulleys 341 on the two trapezoidal lead screws 32 and the synchronous belt 342, a steering pulley 343 is added to cooperate with the synchronous belt 342, so that the synchronous belt 342 bypasses the steering pulley 343 to change the running direction of the synchronous belt 342 here, thereby increasing the wrap angle of the synchronous belt 342 on the synchronous pulley 341. After the wrap angle increases, the number of teeth in contact between the synchronous belt 342 and the synchronous pulley 341 increases, thereby increasing the friction force, enabling the synchronous belt 342 to better transmit power and reducing the possibility of slipping.

[0034] A linear bearing 4 is arranged between the guide rod 22 and the front fixing seat 11. The linear bearing 4 can provide high-precision motion control for the guide rod 22 to ensure the stable operation of the guide rod 22 under high-precision guidance.

[0035] A travel switch is arranged on the tail fixing seat 12, and the travel switch is electrically connected to the driving motor 31. The travel switch is used to detect whether the transmission plate 23 reaches a predetermined position during movement and is used to control the driving motor 31 to stop.

[0036] A plurality of cast iron wheels 5 are arranged at the bottom of the boat pushing plate 21. The cast iron wheels 5 are made of cast iron material. While playing a role in supporting and rolling guidance, they can resist the high-temperature atmosphere of the continuous furnace, enabling the cast iron wheels 5 to operate stably.

[0037] It should be noted that this application is not limited to the above embodiments. The above embodiments are only examples, and embodiments having the same composition and playing the same role and effect as the technical idea within the scope of the technical solution of this application are included in the technical scope of this application. In addition, within the scope of not departing from the main idea of this application, various deformations that those skilled in the art can think of are applied to the embodiments, and other ways constructed by combining some components of the embodiments are also included in the scope of this application.
