Description

Technical Field

[0001] This utility model belongs to the field of handheld microscope technology, specifically relating to a handheld microscope base. Background Technology

[0002] In the inspection and measurement work of circuit boards and semiconductors, handheld microscopes are required to perform high-precision observation and dimensional measurement of delicate structures such as tiny solder joints, circuit paths, and chip pins. This type of work has extremely high requirements for operational stability, because the structure of circuit boards and semiconductor devices is delicate (for example, the spacing between chip pins is often measured in micrometers), and even slight shaking or displacement may cause blurred images, affecting defect identification or measurement accuracy.

[0003] Existing handheld microscope bases have the following shortcomings: First, the disassembly and assembly process is cumbersome, which takes a long time when it is necessary to frequently change the inspection station or adjust the microscope posture, thus affecting work efficiency; Second, they lack stability. Traditional bases are prone to sliding on smooth work surfaces (such as the stainless steel work surface in semiconductor clean rooms and the glass stage of circuit board testing stations), especially when a slight external force is applied during handheld operation, which can easily cause displacement and lead to measurement errors. Utility Model Content

[0004] The purpose of this invention is to provide a handheld microscope base to solve the problems of cumbersome assembly and disassembly process and insufficient stability of existing handheld microscope bases mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a handheld microscope base, comprising a base body and a connecting block fixed to the surface of the base body. Both outer walls of the base body are provided with through holes, and pressing columns are movably connected in the through holes. A connecting plate is fixed to the opposite face of the two pressing columns, and a fixing pin is fixed to the opposite back of the two connecting plates. A fixing spring is fixed between the two connecting plates.

[0006] Two slots are provided on both outer walls of the base body, and baffles are rotatably connected in the slots. Fixed seats are movably connected to both sides of the base body. Two mounting holes are provided on the surface of the fixed seats, and fixed sleeves are installed in the mounting holes. A suction cup is installed at the bottom of the fixed sleeve, and a vent hole is provided on the surface of the suction cup.

[0007] In a further embodiment, both outer walls of the baffle are fixed with connecting columns that are rotatably connected to the base body, and a torque spring is provided on the outside of the connecting columns.

[0008] In a further embodiment, two insert blocks are fixed to one outer wall of the fixing base, and magnetic blocks that attract each other to the base body and the baffle are fixed to the upper and lower outer walls of the insert blocks.

[0009] In a further embodiment, air inlets are provided at corresponding positions of the fixed base and the fixed sleeve, and a movable hole is provided at the top of the fixed sleeve, with a connecting pin movably connected inside the movable hole.

[0010] In a further embodiment, a sealing plug for sealing the air inlet is fixed to the bottom of the connecting pin, and a support spring for supporting the sealing plug is sleeved on the outside of the connecting pin.

[0011] In a further embodiment, a support pad is placed inside the base body, a hand handle is movably connected to the outside of the connecting block, and two fixing grooves matching the fixing pins are opened inside the hand handle. A microscope is provided on one side of the hand handle.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This handheld microscope base uses a fixed spring to support the fixing pin and engage with the fixing groove of the handheld handle, which allows for quick connection between the base and the handheld handle. Pressing the pressing post will disengage the fixing pin from the fixing groove, enabling quick disassembly. This significantly reduces the time spent on workstation adjustments or equipment storage, and improves the efficiency of batch inspection of circuit boards and semiconductor devices.

[0014] The mounting base connects to the slot of the base body via a plug, expanding the function of the base body. It can be tightly attached to a smooth work surface (such as a semiconductor clean room table or a glass table for circuit board testing) via a suction cup. With the sealing plug, the air inlet is sealed, effectively preventing the base from sliding or shaking, reducing vibration interference during hand operation, ensuring clear imaging of microstructures (such as fine wires on circuit boards and chip solder joints) by the microscope, and improving the accuracy of measurement data.

[0015] The baffle can cover the slot, which is not only aesthetically pleasing, but also prevents dust from entering the slot. Under the elastic force of the torque spring, the baffle can always cover the slot without external force.

[0016] Pulling the sealing plug with the connecting pin moves it above the air inlet, allowing external air to enter the suction cup through the air inlet and the vent on top of the suction cup. This allows the suction cup to be quickly separated from the worktable, making it easy to remove the base body from the worktable. This handheld microscope base is not only easy to assemble and disassemble, but also has an expansion function, allowing the installation of suction cups according to the usage environment, ensuring the stability of the connection between the base body and the worktable.

A fixing spring 6 is fixed between the two connecting plates 4. Through grooves are provided on both outer walls of the connecting block 2 for the fixing pins 5 to move. A support pad 18 is placed inside the base body 1, and a handheld rod 19 is movably connected to the outside of the connecting block 2. The handheld rod 19 has two fixing slots that match the fixing pins 5. A microscope 20 is provided on one side of the handheld rod 19. The fixing spring 6 supports the connecting plate 4, so that the fixing pins 5 can be inserted into the fixing slots of the handheld rod 19. The connection and fixing between the base body 1 and the handheld rod 19 can be quickly completed. By pushing the pressing column 3, the connecting plate 4 is moved, so that the two fixing pins 5 move towards each other and the fixing pins 5 are separated from the fixing slots in the handheld rod 19. The handheld rod 19 can be moved upward to quickly complete the disassembly of the base body 1, making it more convenient to carry later.

[0030] Two slots are provided on both outer walls of the base body 1. A baffle 7 is rotatably connected in the slot. A connecting post 8 that is rotatably connected to the base body 1 is fixed on both outer walls of the baffle 7. A torque spring 9 is provided on the outside of the connecting post 8. The baffle 7 can cover the slot, which is not only aesthetically pleasing, but also prevents dust from entering the slot. Under the elastic force of the torque spring 9, the baffle 7 can always cover the slot without external force.

[0031] Both sides of the base body 1 are movably connected to fixed seats 10. Two insert blocks 11 are fixed to one outer wall of the fixed seat 10. Magnetic suction blocks 12 that attract each other to the base body 1 and the baffle 7 are fixed to the upper and lower outer walls of the insert blocks 11. By inserting the insert blocks 11 into the slots of the base body 1, the magnetic suction blocks 12 attract each other to the base body 1 and the baffle 7, which can quickly complete the connection between the fixed seat 10 and the base body 1, ensuring the stability of the fixed seat 10. Two mounting holes are opened on the surface of the fixed seat 10, and a fixed sleeve 13 is installed in the mounting holes. A suction cup 14 is installed at the bottom of the fixed sleeve 13. The surface of the suction cup 14 is provided with ventilation holes. With the setting of the suction cup 14, when the base body 1 is placed on a smooth worktable, it can be attracted to the surface of the worktable, ensuring the stability of the microscope 20, thereby ensuring the accuracy of detection and measurement.

[0032] Air inlets are provided at corresponding positions on the fixed base 10 and the fixed sleeve 13. A movable hole is provided at the top of the fixed sleeve 13.

[0034] In the description of this utility model, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0035] Working principle:

[0036] When the handheld microscope base is connected, the fixing spring 6 pushes the connecting plate 4, causing the fixing pin 5 to be inserted into the fixing groove of the handheld rod 19, thus achieving a stable connection between the base body 1 and the handheld rod 19. This ensures that the relative position of the microscope 20 and the base body 1 is stable during handheld operation. The support pad 18 inside the base body 1 is placed under the circuit board or semiconductor device to provide cushioning protection.

[0037] When placing the base body 1, if the worktable surface is smooth (such as a glass inspection table), insert the plug 11 into the slot of the base body 1. The magnetic block 12 attracts the base body 1 and the baffle 7, quickly completing the connection between the fixing seat 10 and the base body 1. The suction cup 14 is attracted to the table surface after squeezing out the internal air, ensuring the stability of the base body 1. If it is necessary to remove the base body 1, pull the connecting pin 15 to move the sealing plug 16 upward. External air enters the suction cup 14 through the air inlet and the air vent of the suction cup 14. The suction cup 14 is removed from the table surface, completing the operation. The entire process achieves quick disassembly and assembly and stable fixation through structural cooperation, meeting the needs of high-precision and high-efficiency inspection and measurement in the circuit board and semiconductor fields.
