Description

Technical Field

[0001] This invention relates to the field of electronic component assembly and repair technology, specifically an integrated multifunctional workpiece fixing fixture for precision operating microscopes. Background Technology

[0002] In the R&D, repair, and quality inspection stages of the electronics manufacturing industry (such as FPC reinforcing sheet attachment, small component soldering, circuit repair, and visual inspection), operators need to perform long-term, meticulous operations on tiny workpieces under a stereo microscope. Currently, the common practice is for the operator to hold the workpiece in one hand with tweezers or a suction pen while performing the operation with the other. This method has the following significant drawbacks:

[0003] 1) Poor stability: Slight hand tremors are magnified by the microscope, which seriously affects the observation and alignment accuracy, especially when it is necessary to operate with both hands.

[0004] 2) Fatigue: Holding the hand suspended in the air for extended periods can cause fatigue in the operator's hands and wrists, affecting work efficiency and health;

[0005] 3) Low repeatability: Manual positioning cannot accurately reset the position, which is not conducive to performing multiple checks or operations on the same location;

[0006] 4) Occupies both hands: Fixing the workpiece occupies one hand, making it extremely inconvenient when both hands need to be used simultaneously (such as welding or applying glue), or requiring assistance from another person.

[0007] To overcome the shortcomings of the prior art, the present invention provides an integrated multifunctional workpiece fixing fixture for a precision operating microscope. Summary of the Invention

[0008] The purpose of this invention is to provide an integrated multifunctional workpiece fixing fixture for precision operation microscopes, which solves the problem in the prior art that when performing long-term precision operation on tiny workpieces under a microscope, one hand needs to hold tweezers and the other hand needs to operate.

[0009] The objective of this invention can be achieved through the following technical solutions:

[0010] An integrated multifunctional workpiece fixture for a precision operating microscope includes a microscope control console and a workpiece operating stage. The workpiece operating stage includes a stage, a support base is disposed above the stage, an adjustment component and a clamping component that can be adjusted in position under the action of the adjustment component are disposed above the support base, the adjustment component includes guide plates fixedly installed above the support base and symmetrically distributed on both sides, and a guide screw is disposed between the two guide plates to move the clamping component on the surface of the support base along the y-axis.

[0011] As a further embodiment of the present invention: a guide block is slidably connected inside the guide plate at one end, a rotating gear is rotatably connected inside the guide block, and a toothed plate that meshes with the rotating gear is fixedly installed above the support base. By controlling the rotation of the rotating gear and engaging with the toothed plate, the guide block can be driven to slide on the guide plate, thereby driving the clamping assembly to move along the x-axis on the support base.

[0012] As a further embodiment of the present invention: a conversion box is provided inside the guide block, and a first rotating shaft is fixedly connected to the guide screw inside the conversion box. A second rotating shaft is also provided inside the conversion box and below the first rotating shaft. Limiting grooves are provided inside both the first and second rotating shafts. The rotating gear is fixedly connected to the limiting block on the side near the conversion box via a connecting shaft.

[0013] As a further embodiment of the present invention: a limiting rod with a limiting port is fixedly installed on the rotating shaft, and a limiting strip corresponding to the limiting port is fixedly installed on the connecting shaft.

[0014] As a further embodiment of the present invention: a guide wheel is provided on one side of another guide plate and is fixedly connected to the guide screw, and a guide groove corresponding to the position of the guide wheel is fixedly installed on the support base.

[0015] As a further embodiment of the present invention: the clamping assembly includes a slider that meshes with the guide screw, a connecting frame is provided above the slider, and air-pushing frames are fixedly installed on both sides inside the connecting frame. A movable plate is slidably connected inside the air-pushing frame, and a thrust tooth plate is slidably connected inside the air-pushing frame. A rotating gear that meshes with the thrust tooth plate is rotatably connected inside the connecting frame.

[0016] As a further embodiment of the present invention, a clamping plate is detachably provided on the connecting frame.

[0017] As a further embodiment of the present invention, the clamping disk is provided with clamping blocks.

[0018] As a further aspect of the present invention: the support base is provided with a silicone pad for increasing friction on the end face that contacts the stage.

[0019] As a further embodiment of the present invention, an adjustment button is fixedly installed on the outer side of the rotating gear.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This integrated multifunctional workpiece fixture for precision operating microscopes works by adjusting the position of the clamping assembly along the x-axis when the limiting block is inserted into the limiting groove of the second rotating shaft. Since the second rotating shaft rotates inside the conversion box, the rotating gear rotates relative to the conversion box and engages with the gear plate. This movement of the clamping assembly within the conversion box allows for adjustment of the clamping assembly's position along either the x or y axis, eliminating the need for separate adjustments and enabling operation via a single rotating gear. This provides convenience for switching the position of small workpieces during operation. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] like Figure 1 and Figure 2 The diagram shows the overall structure of an integrated multifunctional workpiece fixture for precision operation microscopes. The device includes a microscope control console 10 and a workpiece operating stage 20. The microscope control console 10 is mounted above the workpiece operating stage 20 for observing minute workpieces on the operating stage. The workpiece operating stage 20 includes a stage 21, a support base 22 above the stage 21, an adjustment component 23 above the support base 22, and a clamping component 24 that allows for fine-tuning of the position under the action of the adjustment component 23. The support base 22 has a silicone pad on its end face that contacts the stage 21 to increase friction. Increased friction requires more force to move the support base 22, thus enabling coarse-scale adjustment of the overall position.

[0033] Specifically, such as Figure 3 and Figure 4 As shown, the adjustment assembly 23 includes guide plates 231 fixedly installed above the support base 22 and symmetrically distributed left and right. A guide screw 232, which can be a ball screw, is provided between the two guide plates 231. Under the action of the guide screw 232, the clamping assembly 24 can move along the y-axis on the surface of the support base 22. A guide block 233 is slidably connected inside one end of the guide plate 231. A rotating gear 234 is rotatably connected inside the guide block 233. A toothed plate 235, which meshes with the rotating gear 234, is fixedly installed above the support base 22. By controlling the rotation of the rotating gear 234 and its meshing with the toothed plate 235, the guide block 233 can be driven to slide on the guide plate 231, thereby driving the guide screw 232 and the clamping assembly 24 to move along the x-axis on the support base 22. In this embodiment, by controlling the position of the clamping assembly 24 along the x and y axes, the position and angle of the small workpiece clamped on it can be changed, thereby facilitating subsequent operations.

[0034] However, if the x and y axes need to be adjusted separately each time, it will take a long time to determine the position of the workpiece. Therefore, this application also makes the following improvements.

[0035] like Figure 5 and Figure 6As shown, the guide block 233 has a conversion box 2331 inside. The conversion box 2331 has a first rotating shaft 2332 fixedly connected to the guide screw 232 inside. The conversion box 2331 also has a second rotating shaft 2333 inside and below the first rotating shaft 2332. Both the first rotating shaft 2332 and the second rotating shaft 2333 have limit grooves 2334 inside. The rotating gear 234 is fixedly connected to a limit block 2336 on the side near the conversion box 2331 via a connecting shaft 2335. In this embodiment, by lifting the rotating gear 234 upwards, the limiting block 2336 is driven into the limiting groove 2334 of the rotating shaft 1 2332 under the action of the connecting shaft 2335. At this time, the rotating gear 234 separates from the toothed plate 235. When rotating, it can cooperate with the rotating shaft 1 2332 to drive the guide screw 232 to rotate together, completing the adjustment in the y-axis direction. When the limiting block 2336 moves down and inserts into the limiting groove 2334 of the rotating shaft 2333, because the rotating shaft 2333 rotates inside the conversion box 2331, the rotating gear 234 rotates relative to the conversion box 2331 and meshes with the toothed plate 235, thereby driving the clamping assembly 24 to move along the x-axis direction. In this embodiment, the position adjustment of the clamping assembly 24 on the x-axis or y-axis is achieved by changing the position of the limiting block 2336 inside the conversion box 2331. No separate adjustment is required; it can be accomplished by a single rotating gear 234. This provides convenience for switching the position when operating on small workpieces. An adjustment button is fixedly installed on the outer side of the rotating gear 234, and the rotation of the rotating gear 234 is controlled by adjusting the button.

[0036] Furthermore, a limiting rod 2337 with a limiting port is fixedly installed on the rotating shaft 2332, and a limiting strip 2338 corresponding to the limiting port is fixedly installed on the connecting shaft 2335. When the limiting block 2336 is inserted into the limiting groove 2334, the limiting strip 2338 can also be inserted into the limiting port. This achieves the effect of limiting the position of the limiting block 2336.

[0037] Furthermore, such as Figure 5 and Figure 6 As shown, another guide plate 231 has a guide wheel 236 fixedly connected to the guide screw 232 on one side. A guide groove 237 corresponding to the position of the guide wheel 236 is fixedly installed on the support base 22. In this embodiment, when the guide screw 232 rotates, it drives the guide wheel 236 to rotate inside the guide groove 237; when the guide screw 232 slides, the guide wheel 236 can slide inside the guide groove 237, thereby increasing the smoothness of the guide screw 232 during rotation or movement and improving operational performance.

[0038] like Figure 7 and Figure 8As shown, the clamping assembly 24 includes a slider 241 meshing with the guide screw 232. A connecting frame 242 is provided above the slider 241. Push-air frames 243 are fixedly installed on both sides inside the connecting frame 242. A movable plate 244 is slidably connected inside the push-air frame 243, and a thrust toothed plate 245 is slidably connected to the inner side of the push-air frame 243. A rotating gear 246, meshing with the thrust toothed plate 245, is rotatably connected inside the connecting frame 242. In this embodiment, the rotating gear 246 rotates, causing the thrust toothed plate 245 to slide on the side wall of the connecting frame 242, thereby contacting the movable plate 244. When the movable plate 244 moves into the push-air frame 243, it pushes out the gas inside. When it moves in the opposite direction, the push-air frame 243 moves outward under the action of a return spring to draw in air. A clamping plate 247 is provided on the connecting frame 242. The clamping plate 247 and the connecting frame 242 are detachably connected by a plug-in method. The vacuum suction cup is replaceable and used to adsorb flat workpieces. In this application, when the clamping plate 247 rotates along the z-axis, it can drive the rotating gear 246 to rotate inside the connecting frame 242. When the clamping plate 247 rotates, one of the air-pushing frames 243 on the same side will release air, and the other will suck in air. The air outlet and air inlet of the air-pushing frame 243 are designed with one-way air valves, and the air outlet acts on the clamping plate 247. During the operation of small workpieces, when repeatedly rotating and changing the workpiece angle, the gas generated by the air-pushing frame 243 acts on the clamping plate 236, blowing away debris or other impurities generated in the previous step.

[0039] In addition, a clamping block 248 is provided on the clamping disk 247. The clamping block 248 moves on the clamping disk 247 to achieve positioning and clamping of small workpieces. The position of the clamping block 248 can be adjusted by the feed bolt.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
