Description

Technical Field

[0001] This utility model belongs to the technical field of heat treatment equipment, specifically relating to a salt receiving mechanism that can automatically clean a salt tray. Background Technology

[0002] After heat treatment in the various tanks, workpieces on salt bath heat treatment production lines accumulate a significant amount of salt solution or brine on their surfaces. This drips onto the ground and related equipment during transfer between tanks, severely affecting appearance and polluting the environment. Currently, most salt collection trays on Chinese salt bath heat treatment production lines are fixed, either to the equipment tank or to a frame that moves with the workpieces. Fixed trays require a collection tray for each tank and the connecting sections, resulting in high costs and an unsightly appearance. Furthermore, salt accumulates on the outer walls of each tray over time, making cleaning difficult. Trays fixed to frames can only be cleaned when the production line stops; however, the accumulated salt hardens over time, making manual cleaning extremely time-consuming and labor-intensive. Utility Model Content

[0004] The movable salt receiving device includes a robotic arm, a material rack, and a salt receiving device; the movable salt receiving device is located below the robotic arm, and the material rack is positioned downwards from the robotic arm, with the material rack located above the salt receiving device; the salt receiving device includes a salt receiving frame and a salt receiving tray, and the salt receiving device is connected to the crossbeam of the robotic arm via a guide device; the salt receiving tray is located at the bottom of the salt receiving frame, with its front end rotatably connected to the salt receiving frame, and its rear end overlapping the rear edge of the bottom of the salt receiving frame;

[0005] The cleaning system includes an equipment frame, a lifting device, and a cleaning device. The equipment frame is set on the ground, and the lifting device is set at the rear end of the equipment frame.

[0019] Example 1

[0020] A salt receiving mechanism that can automatically clean the salt tray, such as Figure 1-3 As shown, it includes a movable salt receiving device and a cleaning system.

[0021] The movable salt receiving device includes a robotic arm 4, a material rack 5, and a salt receiving device; the salt receiving device is located below the robotic arm 4, and the material rack 5 is positioned downwards from the robotic arm 4, with the material rack 5 located above the salt receiving tray of the salt receiving device; the salt receiving device includes a salt receiving frame 2 and a salt receiving tray 3, and the salt receiving device is connected to the crossbeam of the robotic arm 4 through a guide device 15; the salt receiving tray 3 is located at the bottom of the salt receiving frame 2, the front end of the salt receiving tray 3 is rotatably connected to the salt receiving frame 2, and the rear end of the salt receiving tray 3 overlaps with the bottom rear end frame of the salt receiving frame 2.

[0022] The cleaning system includes an equipment frame 1, a lifting device 16, and a cleaning device. The equipment frame 1 is set on the ground, and the lifting device 16 is set at the rear end of the equipment frame 1. When the lifting device 16 rises, it can abut against the bottom of the salt receiving tray 3. The cleaning device includes a drainage trough 14 and a water inlet pipe 17. The drainage trough 14 is set on the top surface of the front end of the equipment frame 1, and the water inlet pipe 17 is set at the rear of the equipment frame 1. The water outlet 18 of the water inlet pipe 17 is located above the rear end of the salt receiving tray 3.

[0023] The working principle of this utility model is as follows: This utility model is mainly used for receiving salt and automatically cleaning workpieces transferred between various heat treatment salt tanks in a salt bath heat treatment production line. The robotic arm 4 grasps the material rack 5 and moves along the preset track of the external device, thereby driving the workpieces placed on the material rack 5 to move along the preset processing station on the production line.

[0024] When salt bath heat treatment is required, the guide device 15 is activated to move the salt receiving device away, and the robot arm 4 immerses the material rack 5 into the salt bath treatment mechanism, allowing the workpiece to undergo salt bath treatment within the mechanism. After the salt bath treatment is completed, the material rack 5 is lifted out of the salt bath treatment mechanism by the robot arm 4. At this time, the guide device 15 is reversed, causing the salt receiving device to move under the material rack 5 for receiving salt.

[0025] Then, the robotic arm 4 moves the workpiece, the rack 5, and the salt receiving device to the next process tank. The guide device 15 is activated again to remove the salt receiving device from under the workpiece and the rack 5. The workpiece and the rack 5 are then lowered into the corresponding heat treatment tank, and the process is repeated.

[0026] At the end of the processing step, the robot arm 4 places the workpiece and material rack 5 in the target placement area, and then moves the salt receiving device to the cleaning system station. At this time, the lifting device 16 is activated. When it rises to the highest position, the lifting device 16 lifts the rear end of the salt receiving tray 3, causing the salt receiving tray 3 to tilt. Water from the outlet end 18 begins to enter and clean the salt receiving tray 3. The wastewater after cleaning the salt receiving tray 3 flows into the drainage tank 14 along with the tilt angle of the salt receiving tray 3. The wastewater in the drainage tank 14 can be discharged to the wastewater treatment system for treatment and reused for cleaning the salt receiving tray 3.

[0027] Example 2

[0028] Based on the salt receiving mechanism of the automatically cleanable salt tray in Embodiment 1, such as Figure 1-2 As shown, the guiding device 15 includes: a guide rail 9, a guide wheel 7, a guide motor 8, a guide gear 19, and a guide rack 20. The guide rail 9 and the guide rack 20 are arranged on the left and right sides of the robot arm 4. The guide motor 8 and the guide wheel 7 are arranged on the top of the salt receiving device. The guide gear 19 is arranged at the output end of the guide motor 8. The guide wheel 7 moves along the guide rail 9.

[0029] This setup utilizes the cooperation of guide wheel 7 and guide rail 9, controlled by guide motor 8. The guide motor 8, guide gear 19, and guide rack 20 drive the guide wheel 7 to move along the guide rail 9, thereby influencing the movement of the salt receiving device relative to the robotic arm 4. This method is simple and effective, cost-efficient, reliable, and easy for operators to use.

[0030] Example 3

[0031] Based on the salt receiving mechanism of the automatically cleanable salt tray in Embodiment 1, such as Figure 1-2As shown, the lifting device 16 includes: a lifting frame 11, a lifting motor 10, a lifting gear 12, and a lifting rack 13; a motor bracket is provided at the rear end of the equipment frame 1, and guide grooves are provided on both sides of the rear wall of the equipment frame 1 behind the motor bracket; the lifting motor 10 is provided at the top of the motor bracket, and the output end of the lifting motor 10 is connected to the lifting gear 12; the lifting frame 11 has guide wheels on both sides, the guide wheels are provided in the guide grooves and move up and down along the guide grooves; and a lifting rack 13 that meshes with the lifting gear 12 is provided on the side wall of the lifting frame 11.

[0032] When the salt receiving tray 3 needs cleaning, the lifting device 16 is activated, and the lifting gear 12 at the output end of the lifting motor 10 rotates, causing the lifting rack 13 to drive the lifting frame 11 to rise. The top of the lifting frame 11 lifts the rear end of the salt receiving tray 3, causing the salt receiving tray 3 to tilt until the rear end of the salt receiving tray contacts the water outlet section 18. At this point, the lifting motor 10 is stopped. After the salt receiving tray 3 is cleaned, the lifting motor 10 reverses, causing the lifting frame to descend until the lifting frame 11 returns to its lowest position. At this point, the lifting motor 10 is stopped, and the salt receiving tray 3 returns to a horizontal state.

[0033] The lifting frame 11 is used to lift the salt receiving tray 3, which has a simple structure and occupies a small area, avoiding the problem of excessive space occupied by the equipment frame. The gear and rack transmission can provide sufficient and reliable force for the lifting frame 11 to lift the salt receiving tray 3.

[0034] Example 4

[0035] Based on the salt receiving mechanism of the automatically cleanable salt tray in Embodiment 1, such as Figure 1-2 As shown, the water inlet pipe 17 is equipped with a solenoid valve. When the salt receiving tray 3 reaches the top of the cleaning system, the lifting device 16 rises to its position while the salt receiving tray 3 tilts (e.g., Figure 2 (As shown by the dashed line in the middle), the inlet solenoid valve opens, allowing the cleaning fluid to be sprayed out from the outlet 18.

[0036] This setup allows for automatic control of the cleaning fluid spraying via the lifting device 16.

[0037] Example 5

[0038] Based on the salt receiving mechanism of the automatically cleanable salt tray in Embodiment 1, such as Figure 1-2 As shown, the front end of the salt receiving tray 3 is rotatably connected to the left and right sides of the bottom of the salt receiving frame 2 via a pivot. A pin is provided at the rear end of the salt receiving frame 2, and the salt receiving tray 3 overlaps with the pin on the bottom edge of the rear end of the salt receiving frame 2 when horizontal. This connection method is simple and effective, reducing the manufacturing cost of the salt receiving tray 3 and the salt receiving frame 2.

[0039] Example 6

[0040] Based on the salt receiving mechanism of the automatically cleanable salt tray in Embodiment 1, such as Figure 1-2As shown, the drainage trough 14 is also equipped with a drain outlet, which is connected to the wastewater treatment device through a pipe. When the salt receiving tray 3 is tilted for automatic cleaning, the cleaning waste liquid automatically flows into the drainage trough 14 and is directly discharged into the wastewater treatment device through the pipe, eliminating the need for separate transportation of the drainage trough 14.

[0041] Example 7

[0042] Based on the salt receiving mechanism of the automatically cleanable salt tray in Embodiment 1, such as Figure 3 As shown, the material rack 5 is connected to the robotic arm 4 via an electrically controlled lifting gripper 6. The fixed end of the electrically controlled lifting gripper 6 is fixedly connected to the crossbeam, and a gripper is provided at the lower end of the electrically controlled lifting gripper 6. The gripper is used to grasp or release the material rack 5 (e.g., ...). Figure 3 (As shown by the dashed line).

[0043] The setup allows the electric lifting gripper 6 to control the position of the material rack 5. The lifting action of the electric lifting gripper 6 can be used to lower the gripped material rack 5 to the salt bath treatment mechanism for salt bath treatment, and to pull the gripped material rack 5 up for position transfer.

[0044] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
