Abstract
Description
Technical Field
[0001] This utility model relates to the field of linear module testing technology, specifically to a linear module testing device. Background Technology
[0002] In the field of automated equipment manufacturing, linear modules are the core components for realizing linear motion. Their motion accuracy, such as parallelism and positioning accuracy, directly determines the operational stability and processing precision of automated equipment. Therefore, the motion accuracy detection of linear modules is a key link in the production and maintenance process.
[0003] Currently, the industry relies heavily on manual operation for testing the motion accuracy of linear modules. For example, workers use tools such as rulers and dial indicators to measure the displacement deviation of the linear module slider point by point, and then manually record the data and calculate the accuracy error. This testing method not only requires workers to have a high level of operational proficiency, but the point-by-point measurement process is also time-consuming, making it difficult to meet the rapid testing needs of batch linear modules and seriously affecting production efficiency.
[0004] More importantly, manual measurement is susceptible to subjective operational and environmental factors, leading to insufficient accuracy of the test data. Furthermore, manual measurement can only acquire discrete displacement data, failing to capture the continuous trajectory of the linear module's slider movement. This makes it difficult to detect hidden accuracy issues such as intermittent stuttering and localized misalignment during module movement, resulting in substandard linear modules entering the market, impacting the normal operation of downstream automated equipment, and increasing the quality risks and after-sales costs for enterprises. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a linear module testing device, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a linear module testing device, comprising a base plate for placing the main body of the linear module, a fixing component for fixing the main body of the linear module being installed on the base plate, and a laser emitter being detachably installed on the slide of the main body of the linear module by bolts; A mounting bracket is installed on the base plate. A frame is horizontally installed inside the mounting bracket. A light-transmitting plate is installed inside the frame. A support frame is also installed on the top of the mounting bracket. A camera is installed inside the support frame to record the movement trajectory of the laser emitter on the light-transmitting plate.
[0007] Furthermore, the light-transmitting plate is a white PC diffuser plate and is located directly below the camera.
[0008] Furthermore, the emitting end of the laser emitter faces the direction of the light-transmitting plate.
[0009] Furthermore, the fixing assembly includes two baffles mounted on the upper surface of the base plate, one of the baffles having an internally threaded screw connected to a screw rod, and a clamping plate rotatably connected to one end of the screw rod near the linear module body, with the linear module body fitting between the baffle and the clamping plate.
[0010] Furthermore, the two baffles are arranged in parallel front to back.
[0011] Furthermore, a handle is installed at the end of the screw away from the clamping plate.
[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects: This linear module testing equipment converts the module's motion into a laser trajectory using a laser emitter. The high stability of the laser ensures that the trajectory accurately reflects the module's motion state. The collaboration between the white PC diffuser and the camera clearly captures the light spot trajectory, avoiding subjective errors from manual measurement. The digitized trajectory data facilitates precise analysis of the module's parallelism, positioning accuracy, and other indicators. Compared to traditional testing methods, the test results are more intuitive and reliable, meeting the quality control requirements of high-precision linear modules. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-2 In this embodiment, a linear module inspection device, through the collaboration of a laser emitter 4 and a camera 9, enables the visual capture and recording of the module's motion trajectory, thus meeting the quality inspection requirements of linear modules in automated equipment production. Its structure mainly consists of a base plate 2, a fixing component 3, a laser emitter 4, a mounting bracket 5, a frame 6, a light-transmitting plate 7, a support frame 8, and a camera 9. The components work together to achieve the functions of module fixing, trajectory detection, and data recording.
[0017] Specifically, the linear module body 1 to be tested is placed on the base plate 2, and the fixing component 3 and the mounting bracket 5 are fixedly installed on the upper surface of the base plate 2. The fixing component 3 is located on the base plate 2 and is used to fix the linear module body 1. The mounting bracket 5 spans the base plate 2 and provides an installation base for the frame 6, the light-transmitting plate 7 and the support frame 8.
[0018] In detail, the fixing component 3 is used to stably fix the linear module body 1 to the base plate 2, including two parallel baffles 301, screws 302, clamps 303 and handles 304.
[0019] Two baffles 301 are vertically fixed to the upper surface of the base plate 2, forming the initial limiting space of the linear module body 1. One of the baffles 301 is internally threaded with a screw 302. The end of the screw 302 near the linear module body 1 is rotatably connected to a clamping plate 303 through a bearing. The clamping plate 303 is a flat metal plate that can fit against the module surface. The end of the screw 302 away from the clamping plate 303 is fixed with a handle 304, which makes it easy for the operator to rotate the screw 302.
[0020] In actual use, by rotating the handle 304, the screw 302 can be driven to move the clamping plate 303 towards the linear module body 1. Together with the baffle 301 on the other side, the linear module body 1 is tightly clamped between the baffle 301 and the clamping plate 303 to prevent the module from shifting during testing.
[0021] In addition, the linear module body 1 is fixed on the fixed component 3, and a laser emitter 4 is detachably installed on its slide by bolts. The emitting end of the laser emitter 4 faces the light-transmitting plate 7. After being powered on, it can emit a stable laser beam. The laser beam can move synchronously with the slide of the linear module body 1, converting the movement trajectory of the module into the movement trajectory of the laser on the light-transmitting plate 7.
[0022] Furthermore, the mounting bracket 5 is fixed to the base plate 2, and the internal horizontal fixed frame 6 is a rectangular metal frame used to fix the light-transmitting plate 7. The light-transmitting plate 7 is a white PC diffuser plate, located inside the frame 6 and directly below the camera 9. The white PC diffuser plate has good light transmission and diffuse reflection characteristics, which can clearly present the laser beam emitted by the laser emitter 4 as a light spot, while avoiding strong light directing and affecting the camera 9's shooting. The top of the mounting bracket 5 is fixed to the support bracket 8, and the camera 9 is fixed inside the support bracket 8. The lens of the camera 9 faces the light-transmitting plate 7, which can capture the movement trajectory of the laser spot on the light-transmitting plate 7 in real time, and transmit the trajectory data to an external terminal for storage and analysis, thereby determining whether the movement trajectory of the laser emitter 4 is a straight line.
[0023] In practical applications, before testing, the main body 1 of the linear module to be tested is placed between the two baffles 301 on the base plate 2 to ensure that the movement direction of the module is parallel to the light-transmitting plate 7. The handle 304 is rotated to drive the screw 302 to move the clamping plate 303 toward the module until the clamping plate 303 and the baffle 301 clamp the module together to complete the fixation. The laser emitter 4 is installed on the slide of the main body 1 of the linear module by bolts. The angle of the laser emitter 4 is adjusted so that the emitting end is aligned with the light-transmitting plate 7 to ensure that the laser beam can be projected onto the central area of the light-transmitting plate 7.
[0024] Start the laser emitter 4 and camera 9. The laser emitter 4 emits a laser beam and forms a light spot on the light-transmitting plate 7. Start the linear module body 1 and control its slide to move along a preset path. The laser emitter 4 moves synchronously with the slide, and the laser spot forms a continuous moving trajectory on the light-transmitting plate 7. The camera 9 captures the trajectory of the light spot on the light-transmitting plate 7 in real time and transmits the image data to an external terminal. The staff can observe whether the trajectory is straight through the terminal to judge the motion accuracy of the linear module body 1. If there is a deviation or bending of the trajectory, the error position and error magnitude of the module can be analyzed through the trajectory data recorded by the terminal. After the test is completed, turn off all equipment, rotate the handle 304 in the opposite direction to release the clamp 303, and remove the linear module body 1 and laser emitter 4.
