Description

Technical Field

[0001] The utility model relates to the technical field of crystal positioning, in particular to a crystal compatible positioning mechanism. Background Art

[0002] MOS transistors, or metal-oxide-semiconductor field-effect transistors, are core components widely used in modern electronics. With the continuous advancement of technology, MOS transistors have achieved significant progress in structure, performance, and applications. However, in actual production and application, the precise positioning and installation of MOS transistors still face many challenges, especially when compatibility with multiple specifications is required.

[0003] Traditional MOS transistor positioning mechanisms are often designed for transistors of specific specifications, making them difficult to adapt to the diverse specifications of MOS transistors on the market. The original MOS is positioned by a cover plate, and variations in MOS size require replacement of the cover plate for positioning. If a customer has a wide variety of MOS types, dozens or even hundreds of cover plates may be required, making replacement and maintenance difficult, thus limiting their widespread application. During the installation of MOS transistors, positioning accuracy directly impacts transistor performance and reliability. In existing technologies, positioning accuracy often fails to meet the requirements of high-end applications due to poor positioning mechanism design or low manufacturing precision. While some positioning mechanisms can achieve high positioning accuracy, the operation process is cumbersome, requires professional personnel, and is time-consuming, making it unsuitable for large-scale production and rapid replacement. Summary of the Invention

[0004] In order to overcome the deficiencies of the existing technical solutions, the present invention provides a crystal compatible positioning mechanism, which can effectively solve the problems of multiple crystal specifications and poor compatibility of positioning mechanisms proposed in the background art.

[0005] The technical solution adopted by the present invention to solve the technical problem is as follows: a crystal compatible positioning mechanism includes a frame, a track seat is provided on the frame, the track seat is arranged below the frame, a convex rail and a slider are provided on the track seat, a base is further provided below the frame, and further includes;

[0006] A power module, the power module comprising a vacuum generator and a cylinder;

[0007] A positioning module, the positioning module comprising a positioning plate disposed on a base, the positioning plate being provided with a placement portion, a movable clamp for fixing the crystal being provided on one side of the placement portion, the positioning plate being provided with a stopper, and a spring being provided between the stopper and the movable clamp;

[0008] A suction nozzle is arranged at the movable end of the cylinder, the vacuum generator is connected to the suction nozzle, and the lower end of the suction nozzle is connected to a positioning block, which controls the position of the movable clamp.

[0009] Furthermore, the positioning block is a hollow frustum-shaped plastic block. When the positioning block moves downward, the inclined surface of the frustum contacts the inclined surface of the movable clamp, pushing the movable clamp to move and free up space for placing the crystal.

[0010] Furthermore, a limiting block slidably connected to the positioning plate is provided at the lower end of the movable clamp.

[0011] Furthermore, limiting columns are provided on both sides of the movable clamp, and pressure covers are provided above the limiting columns. The limiting columns and the pressure cover limit and stabilize the moving direction of the movable clamp.

[0012] Furthermore, the positioning plate and the base are in a snap-fit ​​structure.

[0013] Furthermore, the positioning plate is provided with a positioning hole, and the base is provided with a positioning column compatible with the positioning hole.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The combination of the track seat, raised rail and slider allows the user to easily adjust the position of the positioning module on the frame according to the actual size and arrangement requirements of the crystal. This flexibility greatly expands the scope of application of the equipment, enabling it to cope with a variety of different production scenarios and task requirements.

[0016] Through the linkage between the movable clamp and the stop block, as well as the buffering effect of the spring, users can fine-tune the clamping force and position to accommodate crystals of different sizes and shapes, effectively avoiding damage or positioning errors caused by improper clamping.

[0017] The vacuum generator and the cylinder work together: The negative pressure generated by the vacuum generator is stable and reliable, which can firmly adsorb the crystal and prevent it from falling off during movement. The precise control of the cylinder ensures that the suction nozzle can accurately place the crystal in the designated position, greatly improving work efficiency and positioning accuracy.

[0018] The combination of the movable clamp and the spring forms a flexible clamping system that can ensure the stable fixation of the crystal while avoiding damage such as scratches or indentations on the crystal surface.

[0019] The precise control of the cylinder enables the acceleration and deceleration of the crystal to be well controlled during placement, reducing the potential damage to the crystal caused by the impact force generated by sudden acceleration or deceleration.

[0020] The mechanism is seamlessly integrated into the automated production line. By working in collaboration with other automated equipment, it realizes processes such as automatic picking, positioning and placement of crystals, reducing dependence on manual labor and improving the overall automation level of the production line.

DETAILED DESCRIPTION

[0027] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0028] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure. Example

[0029] like Figure 1-4 As shown, the present invention provides a crystal compatible positioning mechanism, including a frame 2, a track seat 4 is provided on the frame 2, the track seat 4 is arranged below the frame 2, a convex rail 5 and a slider 6 are provided on the track seat 4, and a base 9 is further provided below the frame 2, and further includes;

[0030] Power module, the power module includes a vacuum generator 1 and a cylinder 3;

[0031] The positioning module includes a positioning plate 10 provided on the base 9, a placement portion 16 is provided on the positioning plate 10, a movable clamp 11 for fixing the crystal is provided on one side of the placement portion 16, a stopper 15 is provided on the positioning plate 10, and a spring 12 is provided between the stopper 15 and the movable clamp 11;

[0032] The suction nozzle 7 is arranged at the movable end of the cylinder 3, the vacuum generator 1 is connected to the suction nozzle 7, and the lower end of the suction nozzle 7 is connected to a positioning block 8, which controls the position of the movable clamp 11.

[0033] The coordinated arrangement of the track base 4, the raised rails 5, and the sliders 6 provides the entire frame 2 with a high degree of flexibility and adjustability. By adjusting the position of the sliders 6 on the raised rails 5, the relative position of the positioning module on the frame 2 can be quickly changed to accommodate crystals of varying sizes or arrangements. This design enhances the versatility and flexibility of the device.

[0034] The positioning module's positioning plate 10, its mounting portion 16, movable clamp 11, and stop 15 form an adjustable fixation system. The movable clamp 11 is connected to the stop 15 via a spring 12, allowing for adjustment of clamping force and position based on crystal size, thus preventing damage or inaccurate positioning caused by improper clamping.

[0035] The vacuum generator 1 and cylinder 3 in the power module work together to achieve precise picking and placement of the crystal through the suction nozzle 7. The negative pressure generated by the vacuum generator 1 acts on the crystal through the suction nozzle 7 to ensure that the crystal will not fall off during the movement. The precise control of the cylinder 3 enables the suction nozzle 7 to accurately place the crystal to the specified position of the positioning module, which not only improves work efficiency but also ensures the accuracy of positioning.

[0036] The positioning block 8, attached to the lower end of the nozzle 7, is a key component that can be customized to the shape and size of the specific crystal. The synergistic effect of the positioning block 8 and the movable clamp 11 ensures that the crystal is precisely aligned with the preset position during placement, achieving high-precision positioning.

[0037] The positioning block 8 is a hollow frustum-shaped plastic block. When the positioning block 8 moves downward, the inclined surface of the frustum contacts the inclined surface of the movable clamp 11, pushing the movable clamp 11 to move and make room for placing the crystal.

[0038] The frustum-shaped design allows the positioning block 8 to gradually and smoothly contact the inclined surface of the movable fixture 11 during its downward movement. This contact ensures that the movable fixture 11 moves along a predetermined trajectory and distance, thereby precisely controlling the size and position of the vacated space to accommodate the placement requirements of crystals of different sizes.

[0039] By being pushed by the positioning block 8 , the movable fixture 11 can be accurately moved to the appropriate position, providing a stable and precise placement environment for the crystal, optimizing space utilization, and improving the accuracy and efficiency of crystal placement.

[0040] The positioning block 8 made of plastic can provide a gentle thrust when contacting the movable clamp 11, thereby avoiding possible damage or scratches caused by direct collision with metal parts.

[0041] During the process of the positioning block 8 moving down and pushing the movable clamp 11, the frustum-shaped design of the plastic material also has a certain buffering effect, which can reduce the impact and vibration caused by mechanical movement and ensure the stability and safety of the crystal during the placement process.

[0042] See also Figure 1 and Figure 3 The lower end of the movable clamp 11 is provided with a limit block slidably connected to the positioning plate 10.

[0043] The setting of the limit block ensures that the movable clamp 11 can move smoothly along the predetermined trajectory when pushed without tilting or deflecting, which helps to maintain the stability and accuracy of the movable clamp 11 during movement, thereby ensuring that the crystal can be accurately placed in the predetermined position.

[0044] Through the sliding connection between the limiting block and the positioning plate 10 , the movable clamp 11 can be better supported and fixed when subjected to external force, thereby enhancing its overall rigidity.

[0045] See also Figure 3 and Figure 4 Limiting posts 17 are provided on both sides of the movable clamp 11 , and a pressure cover 18 is provided above the limiting posts 17 . The limiting posts 17 and the pressure cover 18 limit the moving direction of the stable movable clamp 11 .

[0046] The limiting column 17 and the pressure cover 18 form a guiding structure, which limits the horizontal movement range of the movable clamp 11. When the movable clamp 11 is pushed or moved, these limiting elements can ensure that it always follows the predetermined trajectory, avoiding positioning errors caused by directional deviation.

[0047] See also Figure 1 and Figure 3 The positioning plate 10 and the base 9 are in a snap-fit ​​structure, and the positioning plate 10 can be replaced according to different crystals.

[0048] The snap-on structure enables the positioning plate 10 to be easily removed and installed from the base 9, allowing the user to quickly replace the appropriate positioning plate 10 according to the size, shape and positioning requirements of different crystals. This greatly improves the flexibility and versatility of the equipment, enabling it to adapt to the processing and testing needs of various crystals.

[0049] When it is necessary to process crystals of different types or specifications, the user does not need to make complicated adjustments or modifications to the entire mechanism, but only needs to simply replace the positioning plate 10, which greatly shortens the preparation time and improves work efficiency.

[0050] The snap-fit ​​structure makes cleaning, inspection and maintenance of the positioning plate 10 more convenient, and the user can easily maintain the positioning plate 10 or replace damaged parts without disassembling the entire mechanism.

[0051] See also Figure 3 and Figure 4 The positioning plate 10 is provided with a positioning hole 13 , and the base 9 is provided with a positioning column 14 compatible with the positioning hole 13 .

[0052] When the crystal is placed on positioning plate 10, positioning posts 14 precisely fit into positioning holes 13, ensuring accurate positioning of the crystal both horizontally and vertically. This significantly reduces positioning inaccuracies caused by manual manipulation or mechanical errors. The tight fit between positioning holes 13 and positioning posts 14 ensures the crystal is stably positioned in the desired location, avoiding machining or testing errors caused by positional deviations.

[0053] After the positioning posts 14 are inserted into the positioning holes 13 , they provide additional stable support for the positioning plate 10 , which helps reduce movement or deformation of the positioning plate 10 caused by vibration, impact or other external forces, thereby ensuring the stability of the crystal during processing or testing.

[0054] During the use of this embodiment, the crystal is taken to the top of the fixture, and after the crystal is placed, the cylinder 3 extends out, and the lifting block pushes the limit block backward through the spring 12 in the inclined cover limit block. After the crystal cylinder 3 is placed in place, the limit block is in place, the crystal suction nozzle 7 is cut off, the crystal is placed in the cover, the crystal cylinder 3 is retracted, and the limit block is rebounded by the spring 12 to support the crystal to complete the positioning.
