One-stop testing and aging production line

Abstract

This invention provides a one-stop testing and aging production line, including a robotic arm assembly. The robotic arm assembly includes a sliding seat, a moving column, a rack, two linear guides, two fixed plates, a gantry frame, a support frame, a first motor, a lifting frame, a second motor, a lifting cylinder, a turntable, a tray, two support rails, four limit rails, a third motor, a lead screw, two slide rails, and a fixed frame. The two ends of the moving column are symmetrically fixed to the adjacent surfaces of the two fixed plates. When the first motor operates, the fixed plates drive the moving column to mesh with the rack. Because the rack's position is fixed, the sliding seat slides along the linear guides, achieving position adjustment of the robotic arm. This method replaces traditional belt and chain drives, eliminating aging problems and providing good stability during operation, thus solving the problems of belt aging and poor chain stability.

Description

Technical Field

[0001] This invention relates to a production line, specifically a one-stop testing and aging production line, belonging to the field of automatic aging technology. Background Technology

[0002] An aging production line is a device used for product aging. It simulates environmental factors (such as temperature, humidity, and pressure) that products might encounter during actual use, subjecting them to prolonged or repeated exposure to determine if they meet performance requirements. An aging production line typically includes multiple functional modules, such as heating, cooling, and pressure modules, which can be combined and adjusted as needed. During the aging process, the product is subjected to alternating environmental factors, such as alternating high and low temperatures and pressure changes, thus simulating the actual usage environment to test the product's stability and reliability. Aging production lines are widely used in electronics, automotive, aerospace, and other fields, playing a crucial role in ensuring product quality and reliability.

[0003] An aging production line typically consists of a conveying system, heating system, cooling system, pressure system, control system, and safety protection system. The control system manages each functional module to simulate environmental conditions such as heating, cooling, and pressurization on the product. Simultaneously, during the aging process, the product is inspected and monitored, recording its performance and any malfunctions. Through repeated exposure and testing, potential problems and faults can be identified, allowing for timely improvements and optimizations to enhance product reliability and stability. Before aging, the product needs to be handled; currently, robotic arms are commonly used for this task.

[0004] For example, the technologies disclosed in CN202310535533.9 "Semi-automatic Aging Chamber for Large-Function Inverters and Energy Storage Products" and CN202223051733.7 "Two-Way Aging Test System" employ a method of adjusting the position of a robotic arm in conjunction with a track and belt or transmission chain, and then using the robotic arm to perform product handling operations. However, this transmission method has the following technical problems:

[0005] (1) Accelerated aging of belts: When the product is subjected to aging test, the transmission belt is close to the aging chamber, so the transmission belt will be affected by environmental factors such as high temperature and humidity, which will cause the transmission belt to age and wear faster.

[0006] (2) Poor stability of the transmission chain: During long-term use, the transmission chain will be affected by environmental factors such as high temperature and humidity, which will cause it to wear faster and the chain to stretch, thus affecting the stability and accuracy of the robot when performing handling operations.

[0007] For example, the technologies disclosed in CN202210634571.5 "A room temperature aging test system" and CN202021244231.4 "Aging chamber" are both based on the core of using a robotic arm to perform handling actions on the product. However, the robotic arm is not flexible enough when performing the actions and it is difficult to move the product to any position in the aging chamber.

[0008] To address this, a one-stop testing and aging production line is proposed. Summary of the Invention

[0041] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0042] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0043] Example 1

[0044] In existing technologies, belt drives and chain drives are used to drive robotic arms. However, the high temperature and humidity environment inside the aging chamber can affect the service life of the belts and accelerate their wear. As for chain drives, the chain can stretch over time, which can affect the stability of the robotic arm during operation.

[0045] like Figure 1 As shown in Figure 13, this embodiment of the invention provides a one-stop testing and aging production line, including a robotic arm assembly 101. The robotic arm assembly 101 includes a sliding seat 11, a toggle column 12, a rack 13, two linear guide rails 14, two fixed plates 15, a gantry frame 16, a support frame 18, a first motor 19, a lifting frame 20, a second motor 21, a lifting cylinder 23, a turntable 24, a tray 25, two support rails 26, four limit rails 27, a third motor 28, a lead screw 29, two slide rails 30, and a fixed frame 41.

[0046] The two ends of the actuating column 12 are symmetrically fixedly connected to the adjacent surfaces of the two fixed plates 15. The upper fixed plate 15 is fixedly connected to the output shaft of the first motor 19. The two linear guide rails 14 are symmetrically fixedly connected to the upper surface of the support frame 18. The rack 13 is fixedly connected to one of the linear guide rails 14. The cylinder shaft of the lifting cylinder 23 is rotatably connected to the center of the lower surface of the turntable 24. The second motor 21 is installed on the lower surface of the tray 25. The output shaft of the second motor 21 is meshed with the turntable 24 through a gear set. The lifting cylinder 23 is installed on the lower surface of the fixed frame 41. The fixed frame 41 is slidably connected to the outer side wall of the two slide rails 30. The two support rails 26 are symmetrically fixedly connected to the upper surface of the lifting frame 20. The lifting frame 20 is threadedly connected to the outer side wall of the two lead screws 29. The four limit rails 27 are symmetrically fixedly connected to the outer side wall of the gantry frame 16. The output shaft of the third motor 28 is fixedly connected to the lead screw 29.

[0047] In one embodiment, the first motor 19 is installed inside the sliding seat 11, which is slidably connected to the upper surface of two linear guide rails 14. The actuating column 12 is meshed with the rack 13. The first motor 19 drives the fixed disk 15 to rotate, and the fixed disk 15 drives the actuating column 12 to rotate, thereby moving the sliding seat 11 and adjusting the position of the tray 25.

[0048] In one embodiment, four guide posts 22 are symmetrically installed on the lower surface of the pallet 25. The four guide posts 22 are rotatably connected to the lower surface of the pallet 25 via a rotating disk. The bottom end of the guide post 22 penetrates the lower surface of the fixing frame 41 and is slidably connected to the fixing frame 41. Two support rails 26 are symmetrically located on both sides of the pallet 25. The guide posts 22 can play a guiding and limiting role to improve the load-bearing capacity of the pallet 25.

[0049] In one embodiment, two slide rails 30 are symmetrically fixedly connected to the upper surface of the lifting frame 20, the bottom end of the lead screw 29 is rotatably connected to the upper surface of the sliding seat 11, the third motor 28 is installed on the top of the gantry frame 16, the lifting frame 20 is slidably connected to the outer side wall of the four limit rails 27, a control box 17 is installed on one side of the gantry frame 16, the bottom of the gantry frame 16 is fixedly connected to the upper surface of the sliding seat 11, the lead screw 29 is driven to rotate by the third motor 28, the lead screw 29 drives the lifting frame 20 through the thread, the lifting frame 20 drives the tray 25, and the tray 25 can be lifted.

[0050] To address the related problems in traditional technologies, this specific implementation method, based on the one-stop testing and aging production line provided above, employs the following technical means or features to achieve a solution:

[0051] (1) Solution to the problems of belt aging and poor transmission chain stability: By fixing a rack 13 on a linear guide rail 14, the actuating column 12 is engaged with the fixed plate 15 and fixedly connected to the first motor 19. When the first motor 19 works, the fixed plate 15 drives the actuating column 12 to mesh with the rack 13. Since the position of the rack 13 is fixed, the sliding seat 11 slides along the linear guide rail 14, realizing the position adjustment of the robot. This method replaces the traditional belt drive and transmission chain drive, and there will be no aging problem. Moreover, it has good stability during operation and solves the problems of belt aging and poor transmission chain stability.

[0052] (2) Solution to the problem of inflexible robot arm movement: The robot arm can move left and right by the cooperation of linear guide rail 14 and sliding seat 11. The robot arm can move up and down by the rotation of lead screw 29 driven by third motor 28 and the lifting frame 20 driven by screw thread. The robot arm can move forward and backward and lift by the cooperation of slide rail 30 and lifting cylinder 23. The robot arm can be loaded by the support rail 26, thus solving the problem of inflexible robot arm movement.

[0053] In summary, the robotic arm in this technology does not suffer from the problems of belt aging and poor stability found in traditional technologies. Furthermore, through the combination of technical structures such as slide rail 30, support rail 26, and tray 25, this technology avoids the problem of inflexible robotic arm movements found in traditional technologies.

[0054] Example 2

[0055] In Example 2, please refer to Figure 1 -5. The test assembly 301 is installed on the outside of the robotic arm assembly 101. The test assembly 301 includes a conveyor box 31, an aging box 32, a radiator 33, a bracket 34, a support wheel 35, two feeders 36, two feeding racks 37, a feeding plate 38, two feeding tracks 39 and a suction cup 40.

[0056] The robotic arm assembly 101 is located inside the conveyor box 31. The support frame 18 is fixedly connected to the inner bottom wall of the conveyor box 31. The aging chamber 32 is installed on the front surface of the conveyor box 31 and communicates with the conveyor box 31. Two feeders 36 are symmetrically located on both sides of the aging chamber 32. The positions of the two feeders 36 correspond to the positions of the inlet and outlet of the conveyor box 31. The bracket 34 is equidistantly installed inside the aging chamber 32. The support wheels 35 are symmetrically installed on the upper surface of the bracket 34. Thus, the test product can be transported into the aging chamber 32 by the robotic arm assembly 101 for aging testing.

[0057] In one embodiment, two feeding racks 37 are symmetrically located on both sides of the conveying box 31, and the positions of the feeding racks 37 correspond to the positions of the feeder 36. Two feeding tracks 39 are symmetrically installed on the upper surface of the feeding racks 37. The feeding plate 38 is slidably connected to the upper surface of the two feeding tracks 39. The suction cups 40 are fixedly connected to the lower surface of the feeding plate 38 at equal intervals. The radiator 33 is installed at equal intervals on the upper surface of the aging chamber 32. The test product is adsorbed by the suction cups 40 and transported to the feeder 36 by the feeding tracks 39 to realize the feeding of the test product.

[0058] In operation, the present invention works as follows: The suction cup 40 adsorbs the test product, and with the cooperation of the feeding track 39 and the feeding plate 38, the test product is conveyed to a feeder 36. The feeder 36 feeds the test product, and then the first motor 19 drives the fixed plate 15, which in turn drives the actuating column 12. The actuating column 12 meshes with the teeth of the rack 13, causing the sliding seat 11 to move along the linear guide rail 14. The sliding seat 11 moves the tray 25 to the position corresponding to the test product. The slide rail 30 drives the fixed frame 41 to move, and the fixed frame 41 moves the tray 25 to below the test product. Then, the lifting cylinder 23 pushes the tray 25 upward, lifting the test product. The slide rail 30 then moves the tray... 25 is reset, the second motor 21 drives the tray 25 to rotate, the tray 25 carries the test product, then the lifting cylinder 23 is reset, the test product falls on the surface of the support rail 26, and the test product is moved to the designated position by the linear guide rail 14. The third motor 28 drives the lead screw 29 to rotate, the lead screw 29 drives the lifting frame 20 through the thread, the lifting frame 20 carries the test product upward to the corresponding position of the bracket 34 by the support rail 26, then the support rail 26 pushes the test product to the support wheel 35 of the bracket 34. At this time, the test product is in the aging chamber 32, and the aging test can be performed on the test product. After the product test is completed, the above steps are repeated, and the test product can be moved to the surface of another feeder 36 to realize the product unloading action.

[0059] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
