Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of SMT chip inspection equipment, specifically an SMT chip optical inspection device. Background Technology
[0002] Surface Mount Technology (SMT) is one of the core technologies in modern electronics manufacturing and plays a crucial role in the production of electronic devices. It has significant advantages such as high assembly density, small size and light weight of electronic products, high reliability and strong vibration resistance. However, in the SMT production process, testing equipment is usually required to inspect it.
[0003] An investigation revealed that a Chinese utility model patent (publication number: CN219695365U) discloses an SMT (Surface Mount Technology) component inspection device. The device includes a base, a support section fixedly extending through the center of the base's top, and a detection component at one end of the base's top. A motor is fixedly installed in the center of the inner bottom wall of the support section. A threaded rod is welded to the end of the motor's drive shaft, and an internal threaded cylinder is threaded onto the outer surface of the threaded rod. Limiting components are provided on both sides of the internal threaded cylinder, and a top plate is adhered to the top of the internal threaded cylinder, located at the inner top of the support section. This design utilizes the motor's drive shaft to rotate the threaded rod. During rotation, the threaded rod drives the internal threaded cylinder, causing the top plate to rise, thereby applying a force to the SMT component placed at the top of the support section, causing the SMT component to disengage from the support section.
[0004] Although the aforementioned patent utilizes a motor's power shaft to drive a threaded rod to rotate, and the threaded rod drives an internal threaded cylinder to lift a top plate, thereby applying a force to the SMT component placed at the top of the support, causing the SMT component to disengage from the support and facilitating its removal, its detector position is fixed and cannot be adjusted in terms of angle or position. For example, when it is necessary to inspect irregularly shaped components or components with special inspection angle requirements, it is impossible to perform comprehensive inspection, which may easily lead to missed defects and affect the inspection accuracy.
[0005] Therefore, this invention provides an SMT (Surface Mount Technology) optical inspection device to solve the above problems. Utility Model Content

[0028] 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.
[0029] Please see Figures 1-6 As shown, the purpose of this embodiment is to provide an SMT (Surface Mount Technology) optical inspection device, including: an operating table 1, a clamping component provided on the inner side of the operating table 1, a limiting groove 101 formed on the upper surface of the operating table 1, a support frame 102 slidably connected to the inner side of the limiting groove 101, and an adjustment component provided at the top of the support frame 102.
[0030] The adjustment assembly includes a mounting box 301. A fixing frame 302 and a rotating seat 303 are fixedly mounted on the inner side of the mounting box 301. A motor A304 is fixedly connected to the inner side of the fixing frame 302. A gear A305 is fixedly connected to the output shaft of the motor A304. A gear B306 meshes with the outer edge of the gear A305. A connecting seat 307 is fixedly connected to one side of the gear B306. One end of the connecting seat 307 is rotatably connected to the inner side of the rotating seat 303. A connecting column 308 is fixedly connected to the other side of the gear B306. A hinge frame 309 is fixedly connected to one end of the connecting column 308 through the outside of the mounting box 301. A hinge seat 310 is hinged to the end of the hinge frame 309. A detector 311 is fixedly connected to the bottom end of the hinge seat 310.
[0031] A mounting bracket 4 is fixedly connected to one side of the hinge frame 309, and a motor B401 is fixedly connected to one side of the mounting bracket 4. The output shaft of the motor B401 passes through the inner wall of the mounting bracket 4 and is fixedly connected to a worm gear 402. A worm wheel 403 meshes with the outer edge of the worm gear 402, and one side of the worm wheel 403 is fixedly connected to the end of the hinge seat 310.
[0032] In this embodiment, by starting the motor A304, its output shaft will drive the gear A305 to rotate. During the rotation of the gear A305, the gear B306 meshes with each other, which will cause the gear B306 to rotate synchronously with the rotation of the gear A305. The gear B306 is rotatably connected to the rotating seat 303 through the connecting seat 307. At the same time, the other side of the gear B306 will drive the hinge frame 309 to rotate through the connecting column 308 fixedly connected to it, which will cause the detector 311 connected to the hinge frame 309 to rotate around the axis of the connecting column 308.
[0033] By starting motor B401, its output shaft drives worm gear 402 to rotate. During the rotation of worm gear 402, it meshes with worm wheel 403, causing worm wheel 403 to rotate. Since worm wheel 403 is fixedly connected to the end of hinge seat 310, the rotation of worm wheel 403 causes hinge seat 310 to rotate around the hinge point of hinge frame 309, thereby flipping the angle of detector 311. This allows detector 311 to inspect SMT components from all directions and multiple angles, which is especially suitable for components with irregular shapes or special inspection angle requirements. It does not miss any possible defects and greatly improves the comprehensiveness and accuracy of SMT component inspection.
[0034] In this embodiment, as Figure 3 and Figure 4 As shown, the clamping assembly includes a clamping platform 201. The outer side of the clamping platform 201 is fixedly connected to the inner side of the operating table 1. Two pairs of limiting grooves 202 are symmetrically provided on the upper surface of the clamping platform 201. A slot 203 is provided between the two pairs of limiting grooves 202 on the upper surface of the clamping platform 201. A clamping member 204 is slidably connected between the inner sides of each pair of limiting grooves 202. A connecting plate 205 is fixedly connected to the bottom end of each clamping member 204. Two hinge members 206 are symmetrically fixedly connected to the lower surface of each connecting plate 205. An adjusting plate 207 is hinged to the end of each hinge member 206. A hinge block 208 is hinged to one end of each adjusting plate 207. A fixing plate 209 is hinged between the ends of each pair of hinge blocks 208. A top shell 210 is fixedly connected between the outer side walls of the two fixing plates 209. The outer side of the top shell 210 is adapted to the inner side of the slot 203.
[0035] An electric telescopic rod 5 is fixedly connected to the inside of the control panel 1, and the output end of the electric telescopic rod 5 is fixedly connected to the upper surface inside the top shell 210.
[0036] In this implementation scheme, when it is necessary to clamp and fix an SMT component for testing, the component to be tested is placed on the clamping stage 201. Then, the electric telescopic rod 5 is retracted. Simultaneously, the output end of the electric telescopic rod 5 pulls the top shell 210 downwards. Since the top shell 210 is fixedly connected to the fixing plate 209, the descent of the top shell 210 synchronously moves the two fixing plates 209 downwards. During the downward movement of the two fixing plates 209, the adjusting plate 20 is adjusted via the hinge block 208. 7. Applying force causes the hinge 206 and connecting plate 205 driven by the adjusting plate 207 to move. The connecting plate 205 is fixedly connected to the clamping member 204, and the clamping member 204 slides in the limiting groove 202. Thus, the two clamping members 204 will move closer to each other under the restriction of the limiting groove 202, thereby clamping the SMT chip placed on the clamping stage 201. While the two clamping members 204 are clamping the SMT chip by moving closer to each other, the lower surface of the SMT chip will be aligned with the port of the slot 203.
[0037] After the test is completed, the electric telescopic rod 5 extends, and its output end pushes the top shell 210 to rise. The rise of the top shell 210 will drive the fixing plate 209 to move upward. Similarly, through the linkage of the hinge block 208, the adjusting plate 207, the hinge 206 and the connecting plate 205, the two clamping pieces 204 slide in the limiting groove 202 and move away from each other, thereby releasing the SMT chip. At the same time, the rising top shell 210 will lift the chip placed on it, making it easier for the operator to pick up the chip.
[0038] In this embodiment, as Figure 1 and Figure 2 As shown, a telescopic cylinder 6 is fixedly connected to the inner side of the top of the support frame 102, and the output end of the telescopic cylinder 6 passes through the inner wall of the support frame 102 and is fixedly connected to the upper surface of the mounting box 301.
[0039] Limiting rods 7 are symmetrically fixedly connected to the upper surface of the mounting box 301, and the outer sides of the two limiting rods 7 are slidably connected to the inner wall of the top of the support frame 102.
[0040] A mounting base 8 is fixedly connected to one side of the operating table 1. A motor C801 is fixedly connected to the inner side of the mounting base 8. The output shaft of the motor C801 passes through the inside of the limiting slide groove 101 and is fixedly connected to a lead screw 802. One end of the lead screw 802 is rotatably connected to the inner side of the limiting slide groove 101, and the outer wall of the lead screw 802 is threadedly connected to the inner wall of the bottom end of the support frame 102.
[0041] In this embodiment, by starting the motor C801, its output shaft will drive the lead screw 802 to rotate. While rotating, the lead screw 802 will slide linearly within the limiting slide groove 101 through the threaded engagement. As the support frame 102 slides, it will drive the entire adjustment assembly to move synchronously in the horizontal direction, so that the detector 311 can reach different horizontal positions of the SMT patch for detection.
[0042] By activating the telescopic cylinder 6, its output end extends or retracts, which pushes or pulls the mounting box 301 to rise or fall synchronously. The limiting rod 7, which is symmetrically fixedly connected to the mounting box 301, slides on the inner wall of the top of the support frame 102, thereby playing a guiding and limiting role, ensuring that the mounting box 301 can only make linear movements in the vertical direction. This enables the vertical height adjustment of the detector 311 to meet the detection needs of SMT components of different thicknesses.
[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
