Technical Field

[0001] This application relates to the technical field of product testing and marking, and in particular to a resistance testing and marking machine. Background Technology

[0002] With the booming development of the electronics industry, electronic devices are becoming increasingly powerful and miniaturized and integrated. As a basic electronic component, fuses are widely used in various electronic devices, and their demand continues to grow.

[0003] Electronic component testing and marking technology is crucial for ensuring the quality and performance of fuses. In the fuse production process, accurate resistance testing and clear product marking help improve production efficiency and product quality, meet market demand for high-quality electronic components, and drive the electronics industry towards a more advanced and efficient direction. At the same time, rapid detection of resistance values ​​and efficient processing of product marking in mass production environments have also become key factors in improving enterprise competitiveness and meeting market supply.

[0004] Currently, the testing process largely relies on manual operation of multimeters or simple testing instruments to measure resistance values. Operators need to manually bring the test probe into contact with the fuse and read the resistance value displayed on the multimeter or testing instrument. In the marking process, manual marking or labeling is typically used. Manual marking involves workers using marking tools to mark the surface of the fuse, while labeling involves pasting pre-printed labels onto the fuse.

[0005] However, the existing testing and marking technologies adopt a semi-automatic production method, which makes the test results prone to errors and the production efficiency low. Summary of the Invention

Detailed Implementation

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] This application discloses a resistance testing marking machine, which improves testing accuracy while increasing production efficiency.

[0030] refer to Figure 1 and Figure 2 A resistance testing and marking machine includes a frame 110, on which a feeding structure 120, a worktable 111, and a discharging structure 130 are arranged. The worktable 111 is sequentially equipped with a temperature detection structure, a resistance detection structure 150, and a marking structure 170. The worktable 111 also has two sets of product flipping structures, located before and after the marking structure 170, respectively. The feeding structure 120 sequentially feeds multiple fuses 1 onto the worktable 111, where the worktable 111 performs temperature detection, resistance detection, and marking operations on the fuses 1. The discharging structure 130 removes the marked fuses 1 from the worktable 111. This configuration automates the resistance testing and marking process of the fuses 1, improving production efficiency and testing accuracy. Specifically, the automated process avoids the tediousness and uncertainty of manual operation, reduces errors caused by human factors, and makes the entire production process more stable and efficient. Meanwhile, the collaborative work of multiple workstations can complete the testing and marking of multiple fuses in a short time, greatly improving the output per unit time.

[0031] For details, please refer to Figure 2 , Figure 3 and Figure 4The feeding structure 120 includes a feeding belt 121, a picking gripper 122, and multiple feeding stops 123. The feeding belt 121 is located on one side of the worktable 111 and serves as the carrier for conveying the fuses 1. The feeding belt 121 can be made of rubber, which has good friction and can stably convey the fuses 1. It can also be made of plastic, which is lighter and less expensive. The multiple feeding stops 123 are evenly spaced along the length of the feeding belt 121. The gap between two adjacent stops is used to place the fuses 1. The picking gripper 122 is used to hold the fuses 1 and transfer them from the feeding belt 121 to the worktable 111. The picking gripper 122 can be a pneumatic gripper for fast response or an electric gripper for high control precision.

[0032] The frame 110 is equipped with a first material handling drive assembly 124 and a second material handling drive assembly 125. The first material handling drive assembly 124 drives the material handling gripper 122 to reciprocate and slide along the length of the feeding belt 121 in a positionable manner. The second material handling drive assembly 125 drives the material handling gripper 122 to reciprocate and slide along the vertical direction in a positionable manner. The first material handling drive assembly 124 and the second material handling drive assembly 125 are connected. Specifically, both the first material handling drive assembly 124 and the second material handling drive assembly 125 are transmission structures for cylinder-driven sliders. Through the cooperation of these two drive components, the material handling gripper 122 can accurately transfer the fuse 1 from the belt to the workbench 111. The material handling gripper 122 is connected to the material handling rotary cylinder 126 and the second material handling drive component 125. This material handling structure 120 design makes the material handling process of the fuse 1 more accurate and efficient, ensuring that the fuse 1 enters the workbench 111 for testing and marking in a predetermined order and position, avoiding confusion and misalignment of the fuse 1 during the conveying process, and improving the overall production efficiency and quality.

The radius of the fixed plate 113 is smaller than that of the turntable 112. The fixed plate 113 is fixedly connected to the frame 110. The turntable 112 is rotatably connected to the frame 110 along its axial direction. In this embodiment, the turntable 112 is driven horizontally via an ER-RU80DT cam divider, converting the continuous rotation of the motor into intermittent indexing motion of the worktable 111. The worktable 111 is equipped with eight fuse fixtures 114. The eight fuse fixtures 114 are arranged at equal angles along the circumference of the turntable 112. The fuse fixtures 114 can be made of plastic to protect the fuse 1, or they can be made of metal to provide better stability. The temperature detection structure, the resistance detection structure 150, a set of product flipping structures, the marking structure 170, and another set of product flipping structures are arranged at intervals along the circumference of the fixed plate 113 and correspond one-to-one with the multiple fuse fixtures 114.

In this embodiment, a total of four copper plate clips 151 are provided, and the four copper plate clips 151 are arranged in pairs to clamp the two ends of the fuse 1 to be tested. The copper plate clips 151 have good conductivity and can accurately measure the resistance value of the fuse 1. The copper plate position adjustment assembly 152 is used to adjust the position of the copper plate clips 151 so that the copper plate clips 151 can be adapted to fuses 1 of different sizes. The copper plate position adjustment assembly 152 is a combination of a cylinder drive 153 and four equal-height screws 154. After the cylinder drive 153 coarsely adjusts the position of the copper plate clips 151, the position of the copper plate clips 151 can be finely adjusted by rotating the equal-height screws 154, so as to accurately adjust the position of the copper plate clips 151.

[0036] refer to Figure 5The product flipping structure includes a rotary drive assembly and a flipping clamping assembly. The flipping clamping assembly achieves a 180-degree flipping action through the rotary drive assembly. The rotary drive assembly is a flipping rotary cylinder 160, and the flipping clamping assembly is a pneumatic gripper 161, which can stably clamp and flip the fuse 1. The marking structure 170 is a laser marking machine, which can clearly mark the detected resistance value onto the end cap of the fuse 1. This workbench 111 design allows the fuse 1 to pass through each station sequentially on the workbench 111, realizing automated temperature detection, resistance detection, product flipping, and marking operations. The temperature detection structure can monitor the temperature of the fuse 1 in real time, reducing the influence of temperature on the resistance test and improving the accuracy of the test. The product flipping structure can easily flip the fuse 1, making the marking operation more convenient and accurate. The marking structure 170 can clearly mark the detected resistance value onto the end cap of the fuse 1, facilitating subsequent identification and management.

The frame 110 is equipped with a discharge belt 115 and a defective product box 116. The length direction of the discharge belt 115 is parallel to the length direction of the feeding belt 121. The defective product discharge assembly 131 is used to transfer the unqualified fuses 1 to the defective product box 116, and the good product discharge assembly is used to transfer the qualified fuses 1 to the discharge belt 115.

[0038] Specifically, the good product discharge assembly includes a discharge gripper 132. A first discharge drive assembly 133 and a second discharge drive assembly 134 are provided on the frame 110. The first discharge drive assembly 133 is used to drive the discharge gripper 132 to slide back and forth along the length of the discharge belt 115. The second discharge drive assembly 134 is used to drive the discharge gripper 132 to slide back and forth vertically. The first discharge drive assembly 133 and the second discharge drive assembly 134 are connected. Both the first discharge drive assembly 133 and the second discharge drive assembly 134 are transmission structures driven by cylinders. Through the cooperation of these two drive assemblies, the discharge gripper 132 can accurately transfer the fuse 1 from the fuse fixture 114 to the discharge belt 115. The discharge gripper 132 is connected to the second discharge drive assembly 134 through the discharge rotary cylinder 135.

[0039] The defective product discharge assembly 131 includes a discharge gripper 1311 and a discharge drive 1312. The discharge gripper 1311 is used to clamp the two ends of the defective fuse 1.

In this embodiment, the discharge drive 1312 also adopts a cylinder-driven slider structure.

[0040] This discharge structure 130 design can separate defective and good products for discharge, which facilitates subsequent processing and management. Defective products can be screened out in a timely manner to prevent them from being mixed with good products, thereby improving product quality and reliability. Good products can then smoothly enter the next process or be packaged, ensuring the continuity and efficiency of production.

[0041] The implementation principle of a resistance testing and marking machine according to an embodiment of this application is as follows: the fuse 1 is conveyed to the workbench 111 through the feeding structure 120. On the workbench 111, it passes through temperature detection, resistance detection, product flipping, marking and other stations in sequence, realizing accurate testing and direct marking of the resistance value of the fuse 1.
