Description

Technical Field

[0001] The present application relates to the technical field of photoelectric coupler processing, and in particular to a crystal plate fixing mechanism. Background Art

[0002] A photocoupler is an electrical-to-optical-to-electrical conversion device that uses light as a medium to transmit electrical signals. It consists of a light source and a light receiver. These two components are assembled in a sealed housing and isolated by a transparent insulator. The light source's pins are the input terminals, while the light receiver's pins are the output terminals. Common light sources are light-emitting diodes, and light receivers are photodiodes, phototransistors, and other types of transistors.

[0003] Optocoupler production requires a die-bonding step. This involves bonding the wafer to a designated area of ​​a holder using a colloid, creating a thermal or electrical path that facilitates subsequent wire bonding. This process is typically performed by specialized die-bonding machines. Modern die-bonding machines are highly automated, significantly improving production efficiency. The wafer is typically placed on a wafer tray, which is then mounted on a machine base.

[0004] Regarding the above-mentioned related technologies, the crystal plate is mostly fixed on the machine base using a quick clamp. Since the contact area between the quick clamp and the crystal plate is small, it is easy to cause poor installation stability, so it needs to be improved. Utility Model Content

The base is used to place the crystal disk. The limit block is connected to the base and is used for the crystal disk to abut against. The first pressing block and the second pressing block are both rotatably connected to the base and are used together to press the crystal disk.

[0008] The movable block is horizontally movable and is arranged on the base. The first pressing block and the second pressing block are both connected to the movable block through compression springs.

[0009] By adopting the above technical solution, during production, the crystal disk is first placed on the base, and the crystal disk is placed against the limit block to achieve preliminary positioning. Then, the first clamping block and the second clamping block are automatically pressed together in cooperation with the first driving member. When the driving member controls the movable block to move backward, the movable block generates an extrusion force on the compression spring, so that the first clamping block and the second clamping block can be pressed on the crystal disk at the same time; when the driving member controls the movable block to move forward, the spring is compressed to control the separation of the first clamping block and the second clamping block, so that the crystal disk can be removed later. By increasing the force area when the crystal disk is compressed, the stability of the crystal disk after installation is improved.

[0010] Preferably, the first driving member is an air cylinder or an oil cylinder, and the piston rod of the air cylinder or the oil cylinder is connected to the movable block.

[0017] By adopting the above technical solution, the rotating motor can drive the first transmission wheel to rotate, and under the connection action of the rack, it can generate a rotational force on the second transmission wheel, thereby driving the base to rotate.

[0018] Preferably, an adjustment component is further included, and the adjustment component is used to adjust the tightness of the rack.

[0019] By adopting the above technical solution, the staff can reasonably control the tightness of the rack according to needs, so as to better drive the base to rotate.

In the absence of conflict, those skilled in the art may combine and combine the different embodiments or examples and features of the different embodiments or examples shown in the present application.

[0036] The embodiment of the present application discloses a crystal plate fixing mechanism. Figure 1 and Figure 2, the fixing mechanism includes a base 1, a limit block 2, a first clamping block 3, a second clamping block 4, a movable block 5 and a first driving member 6. The base 1 is used to place the crystal disk, and the limit block 2 is fixedly connected to the base 1 and is used for the crystal disk to abut. As shown in the figure, the limit block 2 is arranged in an arc shape. The arc-shaped limit block 2 can better fit the crystal disk to increase the contact area and improve the stability of the crystal disk. In some embodiments, an elastic layer (not shown in the figure) is provided on the inner side wall of the limit block 2, and the elastic layer may be but not limited to rubber, sponge and other materials. The elastic layer can play a role in buffering and protecting the crystal disk, reducing damage to the crystal disk.

[0037] Both the first and second compression blocks 3 and 4 are rotatably connected to the base 1. The first and second compression blocks 3 and 4 are arranged in a figure-eight configuration and function together to compress the wafer. A movable block 5 is mounted on the base 1 for horizontal movement. Both the first and second compression blocks 3 and 4 are connected to the movable block 5 via compression springs. A first driver 6 is connected to the movable block 5 and controls its horizontal movement. The first driver 6 is a pneumatic cylinder, hydraulic cylinder, or electric push rod, the piston rod of which is connected to the movable block 5.

[0038] During production, the crystal disc is first placed on the base 1, and the crystal disc is resting on the limit block 2 to achieve preliminary positioning. Then, the first clamping block 3 and the second clamping block 4 are automatically crimped together in cooperation with the first driving member 6. When the driving member controls the movable block 5 to move backward, the movable block 5 generates an extrusion force on the compression spring, so that the first clamping block 3 and the second clamping block 4 can be pressed against the crystal disc at the same time; when the driving member controls the movable block 5 to move forward, the spring is compressed to control the separation of the first clamping block 3 and the second clamping block 4 to facilitate the subsequent removal of the crystal disc. By increasing the force area when the crystal disc is compressed, the stability of the crystal disc after installation is improved.

[0039] Specifically, in this embodiment, the base 1 is rotatably connected to the support disk 11, the rotation axis of the base 1 is in the vertical direction, and the support disk 11 is used to support the base 1. A rotating assembly 7 is also installed on the support disk 11, which is connected to the base 1 and is used to control the rotation of the base 1. The rotating assembly 7 can control the rotation of the base 1, thereby changing the position of the crystal disk, making it convenient for the staff to adjust the crystal disk position according to actual needs and improving practicality. The rotating assembly 7 includes a motor 71, a first transmission wheel 72, a second transmission wheel 73 and a rack 74. The first transmission wheel 72 is connected to the output shaft of the motor 71, and the second transmission wheel 73 is installed on the base 1. The first transmission wheel 72 and the second transmission wheel 73 can both rotate, and the rack 74 is meshed and connected to the first transmission wheel 72 and the second transmission wheel 73. During production, the rotating motor 71 is run, and the rotating motor 71 can drive the first transmission wheel 72 to rotate. Under the connection action of the rack 74, a rotational force can be generated on the second transmission wheel 73, thereby driving the base 1 to rotate.

[0040] Among them, the support disc 11 is also equipped with an adjustment assembly 8, which is used to adjust the tightness of the rack 74. The staff can reasonably control the tightness of the rack 74 as needed to better drive the base 1 to rotate. The adjustment assembly 8 includes a fixed block 81, a screw 82 and a pressure wheel 83. The fixed block 81 is fixedly connected to the support disc 11, the screw 82 is screwed to the fixed block 81, and the pressure wheel 83 is rotatably connected to one end of the screw 82 and is used to press on the rack 74. During adjustment, the staff can rotate the screw 82 so that the screw 82 moves linearly on the fixed block 81, so that the pressure wheel 83 can be pressed against the rack 74, thereby changing the tightness of the rack 74 meshing with the first transmission wheel 72 and the second transmission wheel 73. Since the pressure wheel 83 can rotate, it will not affect the movement of the rack 74.

[0041] In addition, a slide rail 9 is mounted on the side of the support plate 11 away from the base 1. The support plate 11 is slidably connected to the slide rail 9. The support plate 11 is controlled to move on the slide rail 9 by a second drive member 10, which is a cylinder or a screw mechanism of a motor 71. The second drive member 10 can control the movement of the support plate 11 on the slide rail 9, thereby changing the horizontal position of the crystal plate, facilitating subsequent processing and improving practicality.

[0042] The implementation principle of a crystal plate fixing mechanism in the embodiment of the present application is as follows: During production, the crystal plate is first placed on the base 1 and abutted against the limit block 2 to achieve initial positioning. Then, the first and second clamping blocks 3 and 4 are automatically pressed together in conjunction with the first driving member 6 to secure the crystal plate to the base 1. By increasing the force area of ​​the crystal plate during compression, the stability of the crystal plate after installation is improved.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
