Description

Technical Field

[0001] This utility model relates to the technical field of supporting equipment for the production and processing of varistors and ceramic resistors, and in particular to a tunnel furnace loading and unloading workstation. Background Technology

[0002] Currently, the firing and debinding processes of varistor ceramic resistors are carried out in tunnel furnaces. Consequently, each tunnel furnace production line in the existing technology requires two production workers to perform loading and unloading operations to meet the current production and operation requirements of the tunnel furnace. This not only increases the labor intensity of the workers but also restricts the overall working efficiency of the tunnel furnace equipment and has an adverse effect on the production efficiency of the corresponding varistor ceramic resistors.

[0003] In addition, since the temperature of the resistance sheet is high after heating in the tunnel furnace, relying entirely on manual loading and unloading operations is currently dangerous, posing a risk of burns to workers and creating certain safety hazards in the production and processing of varistor ceramic resistance sheets.

[0004] In view of this, how to optimize the loading and unloading process of tunnel furnace in the production of varistor ceramic resistors, reduce the labor intensity and operational risks of relevant personnel, and make the loading and unloading operation of tunnel furnace safer and more efficient is an important technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a tunnel furnace loading and unloading workstation that can significantly optimize the loading and unloading process of the tunnel furnace during the production of varistor ceramic resistor sheets, reduce the labor intensity and operational risks of relevant personnel, and make the loading and unloading operation of the tunnel furnace safer and more efficient.

[0006] To solve the above-mentioned technical problems, this utility model provides a tunnel furnace loading and unloading workstation, including a material conveying device capable of carrying and conveying tunnel furnace saggers. The material conveying device is arranged parallel to one side of the tunnel furnace production line. The first end of the material conveying device is provided with an unloading transfer device capable of transferring tunnel furnace saggers from the tunnel furnace production line to the material conveying device. The tail end of the material conveying device is provided with an loading transfer device capable of transferring tunnel furnace saggers from the material conveying device to the tunnel furnace production line.

[0007] The material conveying device is provided with a material picking station in the middle section. The material picking station is provided with a product storage bin and a raw material storage bin. The material conveying device is provided with a sagger positioning mechanism that is aligned and cooperates with the material picking station. The material picking station is also provided with a material picking robot device that cooperates with the product storage bin, the raw material storage bin and the sagger positioning mechanism respectively.

[0008] Preferably, the sagger positioning mechanism includes a locking mechanism capable of locking the tunnel furnace sagger at the material handling station and a lifting cylinder capable of driving the tunnel furnace sagger to reciprocate up and down.

[0009] Preferably, the locking mechanism includes a locking platform that is linked to the actuating end of the lifting cylinder, and the locking platform is provided with a clamping cylinder capable of clamping the tunnel furnace sagger in the horizontal direction.

[0010] Preferably, the locking mechanism further includes a blocking cylinder capable of abutting against the tunnel furnace sagger in the horizontal direction.

[0011] Preferably, both the unloading and loading transfer devices are cantilever transplanters.

[0012] Preferably, the cantilever transplanter includes a three-axis servo actuator and an electrical control box that cooperate with each other. The horizontal stroke of the three-axis servo actuator is greater than the horizontal width of the material conveying device, and the maximum limit position of the vertical stroke of the three-axis servo actuator is higher than the working surface of the tunnel furnace production line and the working surface of the material conveying device.

[0013] Preferably, the working surface of the material conveying device is flush with the working surface of the tunnel furnace production line.

[0014] Preferably, the actuating end of the three-axis servo motion mechanism is linked to a clamping assembly capable of holding the tunnel furnace sagger.

[0015] Preferably, the material handling robot device includes an industrial robot and a robot arm assembly connected to the end effector of the industrial robot, and the industrial robot further includes a machine vision system.

[0016] Preferably, the material conveying device is a roller conveying device driven by a motor.

[0017] Compared to the aforementioned background technology, the tunnel furnace loading and unloading workstation provided by this utility model, during its operation, involves the unloading and transfer device removing the tunnel furnace sagger fully loaded with processed resistor sheet products from the tunnel furnace production line and placing it on the material conveying device. Then, the material conveying device moves the tunnel furnace sagger fully loaded with resistor sheet products to the material unloading station. At this time, the sagger positioning mechanism reliably locks the tunnel furnace sagger at the corresponding position of the material unloading station. After that, the material unloading robot can remove the resistor sheet products from the tunnel furnace sagger and place them in the product storage bin. Then, the unprocessed resistor sheet raw material is taken out from the raw material storage bin and placed in the tunnel furnace sagger until the resistor sheet raw material in the tunnel furnace sagger can meet the processing needs of the next production process. Then, the sagger positioning mechanism releases the lock on the tunnel furnace sagger, allowing it to continue moving downstream with the material conveying device until the sagger carrying the raw resistance sheet material reaches the loading and transfer device at the end of the material conveying device. The loading and transfer device then removes the sagger carrying the raw resistance sheet material from the material conveying device and places it on the tunnel furnace production line, allowing the tunnel furnace to process the raw resistance sheet material within the sagger to obtain the next batch of resistance sheet products. The tunnel furnace loading and unloading workstation, through the coordinated operation of various actuators, enables the loading and unloading of resistance sheet products and the replenishment of raw resistance sheet material on the tunnel furnace production line. The entire process requires no manual operation, significantly reducing the labor intensity of workers, improving the efficiency of tunnel furnace loading and unloading operations, and effectively eliminating safety hazards such as burns caused by the high temperature of the resistance sheet products. This reduces operational risks associated with loading and unloading operations on the tunnel furnace production line and improves operational safety.

[0018] In another preferred embodiment of this utility model, the sagger positioning mechanism includes a locking mechanism capable of locking the tunnel furnace sagger at the material handling station and a lifting cylinder capable of driving the tunnel furnace sagger to reciprocate up and down. The locking mechanism can reliably lock the tunnel furnace sagger at the material handling station, preventing the tunnel furnace sagger from becoming loose or misaligned when the material handling robot performs loading and unloading operations. Furthermore, the lifting cylinder can lift the entire tunnel furnace sagger to an appropriate height to match the working height of the material handling robot, thereby further improving the material handling accuracy and operational efficiency of the material handling robot.

[0037] Please refer to the reference. Figures 1 to 4 .

[0038] In a specific embodiment, the tunnel furnace loading and unloading workstation provided by this utility model includes a material conveying device 11 capable of carrying and conveying the tunnel furnace sagger 101. The material conveying device 11 is arranged parallel to one side of the tunnel furnace production line 10. The first end of the material conveying device 11 is provided with a unloading transfer device 12 capable of transferring the tunnel furnace sagger 101 from the tunnel furnace production line 10 to the material conveying device 11. The tail end of the material conveying device 11 is provided with a loading transfer device 13 capable of transferring the tunnel furnace sagger 101 from the material conveying device 11 to the tunnel furnace production line 10.

[0039] The material conveying device 11 is provided with a material picking station 14 in the middle section. The material picking station 14 is provided with a product storage bin and a raw material storage bin. The material conveying device 11 is provided with a sagger positioning mechanism that is aligned with the material picking station 14. The material picking station 14 is also provided with a material picking robot device 15 that is aligned with the product storage bin, the raw material storage bin and the sagger positioning mechanism respectively.

[0040] During the specific operation of the equipment, the unloading and transfer device 12 removes the tunnel furnace sagger 101, which is fully loaded with processed resistor sheet products, from the tunnel furnace production line 10 and places it on the material conveying device 11. Then, the material conveying device 11 moves the tunnel furnace sagger 101, which is fully loaded with resistor sheet products, to the material picking station 14. At this time, the sagger positioning mechanism reliably locks the tunnel furnace sagger 101 at the corresponding position of the material picking station 14. Then, the material picking robot device 15 takes out the resistor sheet products in the tunnel furnace sagger 101 and places them in the product storage bin. Then, the unprocessed resistor sheet raw material is taken out from the raw material storage bin and placed in the tunnel furnace sagger 101 until the resistor sheet raw material in the tunnel furnace sagger 101 can meet the processing needs of the next production process. Then, the sagger positioning mechanism releases the lock on the tunnel furnace sagger 101, allowing the tunnel furnace sagger 101 to continue moving downstream with the material conveying device 11 until the tunnel furnace sagger 101 carrying the raw resistance sheet material reaches the loading and transfer device 13 located at the tail end of the material conveying device 11. After that, the loading and transfer device 13 can remove the tunnel furnace sagger 101 carrying the raw resistance sheet material from the material conveying device 11 and place it on the tunnel furnace production line 10, so that the tunnel furnace can process each raw resistance sheet material located in the tunnel furnace sagger 101 to obtain the next batch of resistance sheet products.

[0041] The tunnel furnace loading and unloading workstation can achieve the loading and unloading operations of the resistance sheet products and the replenishment of raw resistance sheet materials in the tunnel furnace production line 10 by relying on the coordinated operation of various action devices. The entire operation process does not require manual operation by the staff, which greatly reduces the labor intensity of the staff, improves the efficiency of the tunnel furnace loading and unloading operation, and effectively eliminates the safety hazards such as burns caused to the staff due to the high temperature of the resistance sheet products. It also reduces the operational risks of the loading and unloading operations of the tunnel furnace production line 10 and improves the operational safety.

[0042] Typically, the material handling robot device 15 includes an industrial robot 151 and a robot arm assembly 152 connected to the moving end of the industrial robot 151. The industrial robot 151 also includes a machine vision system. This machine vision system can identify the resistor sheet products in the tunnel furnace crucible 101, allowing the robot arm assembly 152 to quickly and accurately remove the resistor sheet from the tunnel furnace crucible 101 and transfer it to the product storage area, thereby further improving the working efficiency of the tunnel furnace loading and unloading workstation.

[0043] Generally, a machine vision system may include one or more of a camera, an infrared sensor, or other types of image processing or sensing devices to meet the equipment operation requirements under different working conditions.

[0044] It is easy to understand that in practical applications, the product storage bin can be an empty material pallet 141, while the raw material storage bin can be a tray 142 containing raw resistor sheet material. In this way, by stacking the material pallet 141 and the tray 142, the assembly space required for the product storage bin and the raw material storage bin can be further reduced, and the space utilization of the equipment can be improved.

[0045] Specifically, the sagger positioning mechanism includes a locking mechanism that locks the tunnel furnace sagger 101 at the material handling station 14, and a lifting cylinder that drives the tunnel furnace sagger 101 to reciprocate up and down. The locking mechanism can reliably lock the tunnel furnace sagger 101 at the material handling station 14, preventing the tunnel furnace sagger 101 from becoming loose or misaligned when the material handling robot 15 performs loading and unloading operations. On this basis, the lifting cylinder can lift the tunnel furnace sagger 101 as a whole to an appropriate height to match the working height of the material handling robot 15, thereby further improving the material handling accuracy and operating efficiency of the material handling robot 15.

[0046] More specifically, the locking mechanism includes a locking platform linked to the actuating end of the lifting cylinder, and a clamping cylinder 111 is provided on the locking platform to clamp the tunnel furnace sagger 101 in the horizontal direction. When the material conveying device 11 transports the tunnel furnace sagger 101 to the corresponding position of the material handling station 14, the clamping cylinder 111 actuates to reliably clamp and lock the tunnel furnace sagger 101 in the horizontal direction, so as to ensure the reliable positioning of the tunnel furnace sagger 101, thereby further preventing the tunnel furnace sagger 101 from loosening or misaligning during the subsequent resistance sheet handling process, and ensuring the material handling accuracy and operating efficiency of the material handling robot device 15.

[0047] Based on this, the locking mechanism also includes a blocking cylinder 112 that can abut against the tunnel furnace sagger 101 in the horizontal direction. When the material conveying device 11 transports the tunnel furnace sagger 101 to the material handling station 14, the actuating end of the blocking cylinder 112 extends until the abutting end of the blocking cylinder 112 abuts against the main structure of the tunnel furnace sagger 101, thereby completing the reliable limiting and locking of the tunnel furnace sagger 101.

[0048] Generally, the blocking cylinder 112 can be arranged on the side of the tunnel furnace sagger 101 or below the tunnel furnace sagger 101. The specific arrangement position can be flexibly selected and adjusted in combination with the internal space layout of the material conveying device 11 and the actual working conditions. In principle, as long as it can ensure reliable limiting and locking of the tunnel furnace sagger 101 and meet the actual application needs of the tunnel furnace loading and unloading workstation, it is acceptable.

[0049] On the other hand, both the unloading and conveying device 12 and the loading and conveying device 13 are cantilever transplanters. This type of cantilever transplanter is a conventional integrated device. Although the specific structure of the cantilever transplanter may vary depending on the specific working conditions, its core functions and operating principles can be understood with reference to conventional technology, and will not be elaborated further.

[0050] Specifically, in this solution, the cantilever transplanter includes a three-axis servo actuator 161 and an electrical control box 162 that work together. Multiple foot assemblies 164 can be arranged at the bottom edge of the main structure of the cantilever transplanter to ensure the overall stability and reliable arrangement of the cantilever transplanter. The horizontal travel of the three-axis servo actuator 161 is greater than the horizontal width of the material conveying device 11, and the maximum limit of the vertical travel of the three-axis servo actuator 161 is higher than the working surface of the tunnel furnace production line 10 and the working surface of the material conveying device 11. This setting of the horizontal travel and the maximum vertical limit effectively ensures that the effective range of motion of the cantilever transplanter can fully cover the working range required by the tunnel furnace loading and unloading workstation, thereby fully guaranteeing the accuracy and efficiency of the corresponding tunnel furnace crucible 101 loading and unloading operations.

[0051] Correspondingly, the working surface of the material conveying device 11 is flush with the working surface of the tunnel furnace production line 10. In this way, the height difference of the working surfaces of the unloading transfer device 12 and the loading transfer device 13 when transferring the tunnel furnace sagger 101 can be further reduced, so as to further improve the efficiency of the related tunnel furnace sagger 101 handling operations and avoid collisions or material spillage of the tunnel furnace sagger 101 when it is handled and transferred between the tunnel furnace production line 10 and the material conveying device 11.

[0052] Furthermore, the moving end of the three-axis servo motion mechanism 161 is linked with a clamping assembly 163 capable of holding the tunnel furnace sagger 101. The clamping assembly 163 can be detachably assembled to the moving end of the three-axis servo motion mechanism 161 by bolts, so that the clamping assembly 163 of the corresponding specification can be replaced when necessary according to different working conditions, thereby meeting the needs of the tunnel furnace sagger 101 picking and placing operations under different conditions.

[0053] In addition, the material conveying device 11 is a roller conveying device driven by a conveying motor 113. This type of roller conveying device relies on the motor to drive the chain to rotate in a cycle, so that the rollers arranged in sequence can rotate in coordination, thereby realizing the overall movement of the tunnel furnace sagger 101. The roller structure has a high compatibility with the structure of the tunnel furnace sagger 101, and the stress distribution during the material carrying process is relatively reasonable, which can effectively improve the stability and efficiency of the tunnel furnace sagger 101 in the material conveying device 11.

[0054] Of course, in practical applications, the material conveying device 11 can also be a conveyor belt or other types of material conveying mechanism. However, it should be noted that the selected material conveying mechanism should be able to adapt to the high-temperature working environment of the tunnel furnace, so as to prevent damage to the material conveying device 11 when the high-temperature resistance sheet products are accidentally spilled onto the material conveying device 11.

[0055] In summary, the tunnel furnace loading and unloading workstation provided in this utility model operates as follows: during operation, the unloading and transfer device removes the tunnel furnace sagger, which is fully loaded with processed resistance sheet products, from the tunnel furnace production line and places it on the material conveying device. Then, the material conveying device moves the tunnel furnace sagger, which is fully loaded with resistance sheet products, to the material unloading station. At this time, the sagger positioning mechanism reliably locks the tunnel furnace sagger at the corresponding position of the material unloading station. Then, the material unloading robot removes the resistance sheet products from the tunnel furnace sagger and places them in the product storage bin. Next, the unprocessed resistance sheet raw material is taken out from the raw material storage bin and placed in the tunnel furnace sagger until the resistance sheet raw material in the tunnel furnace sagger can meet the processing needs of the next production process. Then, the sagger positioning mechanism releases the lock on the tunnel furnace sagger, allowing it to continue moving downstream with the material conveying device until the sagger carrying the raw resistance sheet material reaches the loading and transfer device at the end of the material conveying device. The loading and transfer device then removes the sagger carrying the raw resistance sheet material from the material conveying device and places it on the tunnel furnace production line, allowing the tunnel furnace to process the raw resistance sheet material within the sagger to obtain the next batch of resistance sheet products. The tunnel furnace loading and unloading workstation, through the coordinated operation of various actuators, enables the loading and unloading of resistance sheet products and the replenishment of raw resistance sheet material on the tunnel furnace production line. The entire process requires no manual operation, significantly reducing the labor intensity of workers, improving the efficiency of tunnel furnace loading and unloading operations, and effectively eliminating safety hazards such as burns caused by the high temperature of the resistance sheet products. This reduces operational risks associated with loading and unloading operations on the tunnel furnace production line and improves operational safety.

[0056] The tunnel furnace loading and unloading workstation provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
