Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a semi-automatic electrical testing machine. Background Technology

[0002] Traditional electrical testing methods largely rely on manual operation. Workers use simple probes to contact and measure the electrical performance of workpieces one by one. During testing, workers first need to fix the workpiece on a simple fixture, then rely on visual observation and experience to locate the areas to be tested before proceeding with the measurement. Some relatively complex workpieces have multiple measurement steps, which may require multiple adjustments to the probe position and measurement parameters. The operation process is cumbersome and time-consuming, and the test data is unstable. Furthermore, to accommodate workpieces of different shapes and sizes, workers must frequently change fixtures, further reducing testing efficiency and resulting in insufficient production capacity.

[0003] Therefore, the above problems urgently need to be solved. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a semi-automatic electrical testing machine. Through the design of replaceable fixtures and flexible transfer mechanism, it can realize the rapid switching and efficient electrical testing of different workpieces. At the same time, combined with the precise control of the electrical testing mechanism, it can improve testing efficiency and accuracy, reduce equipment costs, and meet the needs of multi-variety, small-batch production scenarios.

[0005] Technical Solution: This utility model provides a semi-automatic electrical testing machine including a frame, a transfer mechanism, and an electrical testing mechanism. The frame contains a worktable; the transfer mechanism is located on the worktable and has replaceable fixtures on it, with workpieces mounted on the fixtures. The transfer mechanism is used to move between different workstations; the electrical testing mechanism is located above the transfer mechanism and is used for electrical testing of the workpieces. The transfer mechanism can move between different workstations on the worktable, realizing automated workpiece transfer in the electrical testing process, improving production efficiency, and reducing the time and physical exertion of manual workpiece handling. The replaceable fixtures on the transfer mechanism are adaptable to different models and specifications of workpieces, enhancing the equipment's versatility. Enterprises do not need to purchase separate electrical testing machines for each type of workpiece, reducing equipment costs. The electrical testing mechanism, located above the transfer mechanism, is precisely positioned and can perform efficient electrical testing on workpieces transferred to corresponding positions, ensuring product quality stability and timely detection of circuit performance defects in the workpieces.

[0006] Furthermore, in this application, a semi-automatic electrical testing machine includes a transfer mechanism comprising a pair of guide rails, a platform, and a first linear drive mechanism. The fixture is mounted on the platform, and the platform is slidably connected to the guide rails via sliders on the guide rails. The first linear drive mechanism is mounted on the worktable to drive the platform to move. The pair of guide rails provide stable and precise guidance for the platform, ensuring that the fixture and workpiece on the platform move strictly according to a preset path during the movement process, avoiding deviation, and ensuring the positional accuracy of the workpiece when transferring between different workstations, enabling precise docking of subsequent electrical testing processes.

[0007] Furthermore, in this application, a semi-automatic electrical testing machine includes a set of guide columns vertically mounted on a worktable. A top plate is mounted on the top of each guide column, and a second linear drive mechanism is mounted on the top plate. The output end of the second linear drive mechanism is connected to an electrical testing component. When the platform moves directly below the electrical testing component, the second linear drive mechanism drives the electrical testing component to move downwards and contact the workpiece for electrical testing. The set of guide columns vertically mounted on the worktable provides a precise guiding structure for the vertical movement of the electrical testing component, ensuring that the component does not deviate during lifting and is always precisely aligned with the workpiece on the platform below, thus guaranteeing the accuracy of the electrical testing contact point. The second linear drive mechanism, connected to the electrical testing component, has precise stroke control capabilities. According to a preset program, it can drive the electrical testing component to move quickly and accurately downwards to contact the workpiece the instant the platform is positioned, achieving automated electrical testing triggering and strictly controlling the product's electrical performance testing process.

[0008] Furthermore, in a semi-automatic electrical testing machine of this application, the electrical testing component includes a movable plate disposed between a worktable and a top plate. A guide post passes through the movable plate, and a second linear drive mechanism drives the movable plate to move up and down along the guide post. A set of support rods is mounted downwards on the movable plate, and a carrier plate is mounted at the lower end of each support rod. A set of probes is mounted on the carrier plate for electrical testing of the workpiece. The movable plate, as a key connecting component, is located between the worktable and the top plate and is connected by the guide post. This allows it to move stably up and down along the guide post under the action of the second linear drive mechanism, and also provides stable support for subsequently installed components, ensuring the continuity and coordination of the entire electrical testing component's operation. The set of probes mounted on the carrier plate is specifically designed for electrical testing of the workpiece and can make precise contact with the corresponding detection points on the workpiece.

[0009] Furthermore, in a semi-automatic electrical testing machine of this application, the fixture includes a base plate, on which a first carrier block and a second carrier block are provided. The first and second carrier blocks are spaced apart. One end of the workpiece is embedded in the first carrier block, and the other end has a circular hole fitted into a set of pins on the second carrier block. The spaced arrangement of the first and second carrier blocks forms a specific spatial layout, which can position both ends of the workpiece separately. By embedding one end into the first carrier block and the circular hole at the other end fitting into the pins of the second carrier block, precise positioning of the workpiece in two directions in the plane is achieved, ensuring that the workpiece will not move arbitrarily during transfer and electrical testing, and its position remains relatively fixed.

[0010] Furthermore, in a semi-automatic electrical testing machine of this application, a pair of limiting blocks are also provided on the worktable. These limiting blocks are used to limit the platform between different workstations, and adjusting screws are threaded through the limiting blocks. The core function of the pair of limiting blocks on the worktable is to accurately limit the platform between different workstations. When the platform moves to the corresponding workstation under the drive of the transfer mechanism, the limiting blocks can prevent the platform from moving further, ensuring that the platform accurately stops at the preset electrical testing or other operational position. This ensures that subsequent processes, such as contact testing of electrical testing components with the workpiece, can be carried out smoothly and accurately. The adjusting screws on the limiting blocks allow the position of the limiting blocks to be flexibly adjusted according to actual production needs. By rotating the adjusting screws, the relative position of the limiting blocks on the worktable can be changed, thereby adapting to the requirements of platform limiting position under different workpiece specifications, different electrical testing processes, or different workstation layouts, enhancing the adaptability of the equipment to diverse production scenarios.

[0011] Furthermore, in one of the semi-automatic electrical testing machines described in this application, a touch screen is also provided on the upper part of the frame. The touch screen is used to select the electrical testing scheme and display the electrical testing results. As a key component of human-computer interaction, the touch screen provides operators with a convenient operating interface.

[0012] Furthermore, in one of the semi-automatic electrical testing machines of this application, the bottom of the frame is also provided with a set of rollers and a base. The set of rollers gives the semi-automatic electrical testing machine good mobility, while the base provides stable support for the entire electrical testing machine.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0014] 1. The semi-automatic electrical testing machine of this utility model is adapted to different models and specifications of workpieces by means of replaceable fixtures on the transfer mechanism, which enhances the versatility of the equipment. Enterprises do not need to purchase electrical testing machines separately for each type of workpiece, which reduces equipment costs. At the same time, the transfer mechanism can move between different workstations to realize the automated flow of workpieces in the electrical testing process, which improves production efficiency and reduces the time and physical labor consumption of manual handling of workpieces.

[0015] 2. The semi-automatic electrical testing machine of this utility model constructs a precise guiding structure for the electrical testing components through the vertically installed guide columns in the electrical testing mechanism. Combined with the precise stroke control capability of the second linear drive mechanism, it ensures that the electrical testing components are precisely aligned and in precise contact with the workpiece, realizes automated electrical testing triggering, strictly controls the product electrical performance testing process, ensures the accuracy and stability of electrical testing results, improves testing efficiency and accuracy, and meets the needs of multi-variety, small-batch production scenarios.

Detailed Implementation

[0022] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-5 The semi-automatic electrical testing machine shown includes a frame 1, a worktable 2, a transfer mechanism 3, a fixture 4, a workpiece 5, and an electrical testing mechanism 6.

[0024] The frame 1 has four casters 12 and four bases 13 at its bottom. The four casters 12 are evenly distributed near the four corners of the bottom of the frame 1, facilitating short-distance movement of the equipment within the workshop and allowing for easy adjustment of the equipment position according to the production layout. The four bases 13 provide stable support for the equipment, ensuring that it does not shake or shift during operation and guaranteeing the accuracy of the test. A touch screen display 11 is installed on the upper part of the frame 1, allowing operators to conveniently select different electrical test schemes and view the electrical test results in real time.

[0025] A pair of limiting blocks 21 are provided on the workbench 2, and each limiting block 21 is equipped with an adjusting screw 211. The limiting blocks 21 are used to precisely limit the position of the platform 32 between different workstations. In the initial state, the platform 32 is located at the first workstation, that is, close to one of the limiting blocks 21. At this time, the operator can place the workpiece 5 on the fixture 4. The fixture 4 includes a base plate 41, on which a first carrying block 411 and a second carrying block 412 are arranged at intervals. One end of the workpiece 5 is tightly embedded in the first carrying block 411, and the round hole at the other end is accurately fitted into a set of pins 4111 on the second carrying block 412. In this way, the workpiece 5 is stably limited in two directions in the plane, ensuring that the workpiece 5 will not shift during subsequent movement and testing.

[0026] The transplanting mechanism 3 includes a pair of guide rails 31, a platform 32, and a first linear drive mechanism 33. The fixture 4 is mounted on the platform 32, which is slidably connected to the guide rails 31 via sliders 34 on the guide rails 31. The first linear drive mechanism 33 is a cylinder mounted on the worktable 2, with its piston rod connected to the platform 32. After the operator places the workpiece 5 on the fixture 4, the first linear drive mechanism 33 is activated, extending the piston rod of the cylinder and pushing the platform 32 along the guide rails 31 towards the second limiting block 21. Due to the guiding effect of the guide rails 31, the platform 32 can move smoothly and accurately to the designated position, ensuring precise connection for subsequent electrical testing procedures.

[0027] The electrical testing mechanism 6 includes four guide posts 61 vertically mounted on the worktable 2, a top plate 62, a second linear drive mechanism 63, and an electrical testing assembly 64. The four guide posts 61 are rectangularly distributed on the worktable 2, providing a highly stable and precise guiding structure for the vertical movement of the electrical testing assembly 64. The top plate 62 is mounted on the top of the guide posts 61, and the second linear drive mechanism 63, a cylinder, is mounted on the top plate 62. The electrical testing assembly 64 includes a moving plate 641 located between the worktable 2 and the top plate 62. The four guide posts 61 pass through the moving plate 641, ensuring that the moving plate 641 does not shift during movement. Four support rods 642 are mounted downwards on the moving plate 641, and a carrier plate 643 is mounted at the lower end of the four support rods 642. A set of probes 644 are evenly mounted on the carrier plate 643. Once the stage 32 moves directly below the electrical testing component 64 and is accurately positioned by the second limiting block 21, the piston rod of the cylinder of the second linear drive mechanism 63 extends, driving the moving plate 641 to move quickly and precisely downwards along the guide post 61. During the movement, due to the guidance of the guide post 61 and the stable support of the support rod 642, the probe 644 on the stage 643 can accurately contact the corresponding detection point of the workpiece 5, realizing automated electrical testing triggering and detecting the electrical performance of the workpiece 5. After the test is completed, the piston rod of the cylinder of the second linear drive mechanism 63 retracts, driving the electrical testing component 64 to move upwards back to the initial position. The stage 32 can then return to the first workstation under the action of the first linear drive mechanism 33 to perform the testing operation on the next workpiece.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
