[0001] The utility model relates to the technical field of image measuring instruments, in particular to an image measuring instrument. Background Art

[0002] With the rapid development of modern manufacturing, the requirements for the quality inspection of welding wires of precision workpieces and electronic products are increasing. As a high-precision optical image measuring instrument, the image measuring instrument plays an important role in the quality inspection of welding wires of precision workpieces or electronic products. The image measuring instrument is usually composed of a high-resolution color lens, a continuously variable magnification objective lens, and a high-precision workbench structure. By capturing and processing the image data of the target workpiece, it can accurately detect quality problems such as welding wire offset.

[0003] In the practical application of image measuring instruments, precise positioning of electronic products and protection of lenses and objective lenses are the key to ensuring measurement accuracy. However, there are some limitations in the prior art. For example, referring to the technical solution described in patent document CN217017742U, although the camera is protected by the extension and contraction of the telescopic rod, and the camera is prevented from being contaminated during storage, this protection method is prone to cause friction loss between the camera and the shielding plate, thereby affecting the clarity and accuracy of vision during measurement. In addition, frequent movement of the camera to adjust the detection position of the electronic product is also prone to wear and shaking of the moving components, thereby reducing the stability of the measurement.

[0004] In response to the above problems, this technology proposes an improved image measuring instrument design scheme. This scheme aims to reduce the friction loss between the camera and the shielding plate by optimizing the protection mechanism of the lens and the objective lens; at the same time, by improving the design of the moving components, the stability and accuracy of the camera movement are improved, thereby ensuring the efficient, accurate and stable quality inspection of the welding wire of electronic products.

[0013] Further, the longitudinal component further includes a slide rail, and a sliding plate connected to the placement plate and slidably matched with the slide rail; the longitudinal component further includes a first driving component for driving the sliding plate to move longitudinally.

[0031] The principles and features of the present utility model will be described below with reference to the drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0032] It should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" in the terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For those of ordinary skill in the art, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0033] As described in the background technology, the squeezing of the camera against the baffle plate can easily lead to friction loss between the camera and the baffle plate, resulting in blurred vision, scratches and other problems during measurement, and the moving components of the mobile camera are prone to wear and shaking after the camera is frequently moved. For this reason, this embodiment provides an image measuring instrument, which can solve the problems existing in the image measuring instrument in the prior art, increase the service life of the camera, and avoid camera wear. By adjusting the positioning position of the electronic product, there is no need to adjust the position of the measuring instrument, which can facilitate the stability of the measurement of the electronic product to meet the measurement of the electronic product and the stability of the measuring instrument camera.

[0034] See also Figure 1 - Figure 4 This embodiment proposes an image measuring instrument, including a detection table 1, a slide rail 5 and a placement plate 7 stacked in sequence from bottom to top, and a longitudinal component connected to the placement plate 7 is provided on the slide rail 5, and the longitudinal component is used to drive the placement plate 7 to move longitudinally.

[0036] The longitudinal component also includes a sliding plate 6 slidably mounted on the outside of the two slide rails 5, the outer surface of the sliding plate 6 is slidably connected to the sliding groove set on the bottom surface of the placement plate 7, and the longitudinal component also includes a first driving component for driving the sliding plate 6 to move longitudinally.

[0037] By setting up two slide rails 5, the sliding plate 6 can be easily moved longitudinally under the limiting and supporting action of the slide rails 5, and then the placement plate 7 can be driven to perform longitudinal adjustment movement of the electronic product, so that the electronic product can be moved longitudinally to the detection area for detection.

[0038] The first driving assembly includes a wire seat 8 fixedly connected to the bottom surface of the sliding plate 6, two first limit blocks 9 fixedly connected to the upper surface of the detection platform 1, and a first screw rod 10 threadedly matched with the internal thread of the wire seat 8; the front and rear sections of the first screw rod 10 are respectively rotatably connected to the inner wall of the first limit block 9, and the front end of the first screw rod 10 rotates through the inner wall of the first limit block 9 on the same side and is fixedly connected to a first rocker arm 11 for driving the first screw rod 10 to rotate.

[0039] By setting the first lead screw 10 and rotating the first lead screw 10, the first lead screw 10 is in threaded engagement with the screw base 8 to drive the screw base 8 to move longitudinally at the first lead screw 10. Further, the sliding plate 6 is driven by the screw base 8 to move longitudinally. Moreover, there is a thread self-locking property between the first lead screw 10 and the screw base 8, which can avoid the situation where manually pushing the sliding plate 6 to adjust the position longitudinally is not ideal.

[0040] The setting of the first rocker arm 11 can better facilitate the operator to manually rotate the first rocker arm 11 to drive the first lead screw 10 to rotate, thus greatly improving the practicability of the overall device and the convenience of operation.

[0041] A transverse component connected to the longitudinal component is provided inside the placement plate 7. The transverse component is used to drive the placement plate 7 to move horizontally. The setting of this transverse component can facilitate the adjustment of the horizontal movement of the placement plate 7. Further, the electronic product can be driven by the placement plate 7 to adjust the horizontal position. The mutual cooperation of the transverse component and the longitudinal component can facilitate the detection work of the electronic product at different positions according to requirements.

[0042] The transverse component further includes two second limit blocks 12 fixedly connected to the sliding plate 6 and a second lead screw 13 in threaded engagement with the inner wall of the placement plate 7. The left and right ends of the second lead screw 13 are respectively rotatably connected to the inner walls of the second limit blocks 12 on the same side. The right end of the second lead screw 13 rotatably penetrates the inner wall of the second limit block 12 on the same side and is fixedly connected to a second rocker arm 14 for driving the second lead screw 13 to rotate.

[0043] By setting the second lead screw 13 and rotating the second lead screw 13, the second lead screw 13 is in threaded engagement with the placement plate 7, so that the placement plate 7 can be driven to move horizontally. Further, it is convenient to adjust the horizontal position of the electronic product and facilitate the detection of electronic products at different positions.

[0044] The setting of the second rocker arm 14 can facilitate the operator to manually rotate the second rocker arm 14 to drive the second lead screw 13 to rotate, improving the convenience of the operator to rotate the second lead screw 13.

[0045] An optical microscope main body 2 is fixedly connected to the upper surface of the detection table 1, and a microscope lens 3 is installed at the connection end of the optical microscope main body 2. A protection mechanism 4 for clamping and protecting the microscope lens 3 is provided inside the optical microscope main body 2. Through the setting of the protection mechanism 4, it is convenient for the protection component to protect the lens of the microscope lens 3, avoiding the microscope lens 3 being exposed to the air for a long time without use and suffering from the adhesion of dust or dirt, thereby being able to avoid the detection work of the microscope lens 3 on the electronic product.

[0046] The protection mechanism 4 includes two first mounting blocks 404 fixedly connected to the outer surface of the optical microscope body 2, two L-shaped protection plates 405 hinged to the first mounting blocks 404 and respectively facing the two sides of the microscope lens 3, and a transmission assembly connected to the two L-shaped protection plates 405; the transmission assembly is used to drive the L-shaped protection plates 405 to expand or close the protection of the bottom of the microscope lens 3.

[0047] By setting up an L-shaped protective plate 405, a reserved groove is opened at the protective part of the L-shaped protective plate 405, which can facilitate the protection of the microscope lens 3 by opening or closing, and a distance value is set between the reserved groove of the L-shaped protective plate 405 and the bottom end of the microscope lens 3, which can avoid the risk of damage caused by scratches caused by the L-shaped protective plate 405 contacting the bottom end of the microscope lens 3.

[0048] The transmission assembly includes two second mounting blocks 406 fixedly connected to the outer surface of the L-shaped protective plate 405, a transmission plate 403 and a fixed ring 402 which are hinged to each other with the second mounting blocks 406 in sequence; when the fixed ring 402 moves laterally, the transmission plate 403 and the L-shaped protective plate 405 swing back and forth, so that the L-shaped protective plate 405 opens or closes the protection of the microscope lens 3.

[0049] By setting a fixing ring 402, the fixing ring 402 can pull the transmission plate 403 to move when it moves horizontally, and the transmission plate 403 can be limited by the second mounting block 406 when it moves, so that the transmission plate 403 can pull the second mounting block 406 and the L-shaped protective plate 405 to expand or close, so that the L-shaped protective plate 405 can protect the microscope lens 3 when it is closed.

[0050] The protection mechanism 4 also includes a two-way hydraulic cylinder 401 connected to two fixed rings 402, and the two-way hydraulic cylinder 401 is embedded in the interior of the optical microscope body 2. By setting the two-way hydraulic cylinder 401, the two output ends of the two-way hydraulic cylinder 401 can simultaneously push the two fixed rings 402 to move laterally, so that the fixed rings 402 drive the L-shaped protection plate 405 to expand or close through transmission, thereby protecting the microscope lens 3, greatly improving the practicality of the overall device.

[0051] Two mounting plates 15 for mounting the optical microscope body 2 on the detection platform 1 are fixedly connected to the outer surface of the optical microscope body 2 , and supporting legs 16 and foot pads 17 for supporting the detection platform 1 are fixedly connected to the four corners of the bottom surface of the detection platform 1 .

[0052] By providing the mounting plate 15 , it is possible to facilitate installation and disassembly of the optical microscope body 2 , and improve the stability of the optical microscope body 2 installed on the testing platform 1 , so as to facilitate disassembly and maintenance of the optical microscope body 2 .

[0053] The provision of the support legs 16 and the foot pads 17 facilitates the placement and movement of the overall device, and also helps to enhance the stability of the overall device, preventing shaking during the measurement of electronic products and thus avoiding inconvenient detection.

[0054] Working principle: When measuring chips, workpieces, etc., first place the workpiece on the placement plate 7. Then, by rotating the first rocker arm 11, the first lead screw 10 is driven to rotate, causing the first lead screw 10 to drive the nut block 8 and the sliding plate 6 to move horizontally. The sliding plate 6 is limited by the slide rail 5 during horizontal movement, which facilitates the stability during horizontal movement. When adjusting to another position, rotate the second rocker arm 14, which drives the second lead screw 13 to rotate, causing the second lead screw 13 to drive the placement plate 7 to move horizontally in the other direction, enabling the placement plate 7 to drive the workpiece to adjust to different positions. At this time, start the double-acting hydraulic cylinder 401. The two output ends of the double-acting hydraulic cylinder 401 drive the two fixed rings 402 to move. During the movement of the fixed rings 402, the transmission plate 403 is driven to move synchronously, and the transmission plate 403 pushes the L-shaped protective plate 405 to move through the second mounting block 406. The L-shaped protective plate 405 swings under the limiting action of the first mounting block 404, enabling the two L-shaped protective plates 405 to close and protect the microscope lens 3. This can prevent dust or dirt from adhering to the detection area of the microscope lens 3 when it is not in use, avoiding the detection effect of the microscope lens 3 during the soldering and wire bonding of electronic products, workpieces, etc., and preventing friction damage to the microscope lens 3 caused by contact with it, greatly enhancing the practicality of the overall device and the service life of the microscope lens 3.
