Description

Technical Field

[0001] This utility model relates to the field of transistor packaging technology, and in particular to an image positioning device. Background Technology

[0002] TO packages consist of a socket and a cap. The socket primarily houses the chip circuitry and some optical components, while the cap provides focusing or transmission sealing for optical functions. Together, they form an active circuit and an optical collimation mechanism, ultimately achieving photoelectric conversion and optimizing device functionality. Therefore, ensuring the coaxiality of the optical components on the cap and socket is a key factor in optimizing photoelectric conversion efficiency. Existing TO packaging soldering equipment typically uses an image positioning device with a camera to identify the coaxiality of the socket and cap. However, some TO packaging soldering equipment lacks sufficient space above the soldering position to accommodate the image positioning device. Therefore, it is necessary to provide an image positioning device that can be positioned to the side of the object to be positioned. Utility Model Content

[0025] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0026] Please refer to Figure 1 and Figure 2 An image positioning device includes a camera 1 and a mounting base 2. The mounting base 2 is provided with a first optical channel 21 and a second optical channel 22 that are connected to each other. The end of the first optical channel 21 away from the second optical channel 22 is connected to the outer wall of the mounting base 2 to form a first window. The end of the second optical channel 22 away from the first optical channel 21 is connected to the outer wall of the mounting base 2 to form a second window. A reflector 23 is provided at the connection between the first optical channel 21 and the second optical channel 22. The camera 1 is located outside the first window.

[0027] As can be seen from the above description, the beneficial effects of this utility model are as follows: This image positioning device uses the reflector 23 to change the direction of light propagation, so that the camera 1 set on the side of the fixed base 2 can receive the light beam propagating along the extension direction of the second light channel 22, so that this image positioning device can be set on the side of the object to be positioned, reducing the space occupied in the vertical direction.

[0028] Furthermore, the extension direction of the first optical channel 21 is perpendicular to the extension direction of the second optical channel 22.

[0029] Furthermore, it also includes a translation drive mechanism 3, which is used to drive the camera 1 to move closer to or away from the fixed base 2 along a first direction, the first direction being parallel to the extension direction of the first optical channel 21.

[0030] As described above, the translation drive mechanism 3 is used to adjust the distance between the camera 1 and the reflector 23, thereby adjusting the imaging quality of the camera 1.

[0031] Furthermore, it also includes a mounting base 4, a mounting block 5, and a locking element 6. The mounting block 5 is mounted on the mounting base 4 and is movable relative to the mounting base 4 in a second direction, which is perpendicular to the first direction. The mounting base 4 is driven to connect with the translation drive mechanism 3. The camera 1 is mounted on the mounting block 5. The locking element 6 is used to lock the relative positional relationship between the mounting base 4 and the mounting block 5.

[0032] As described above, the mounting block 5 can be moved relative to the mounting base 4 to adjust the relative position of the camera 1 and the reflector 23 in the second direction, thereby making the camera 1 accurately aligned with the object to be positioned.

[0033] Furthermore, the mounting block 5 is provided with an elongated hole 51, the length direction of which is parallel to the second direction, and the locking member 6 passes through the elongated hole 51 and is detachably connected to the mounting base 4.

[0035] Furthermore, the locking member 6 is provided with an external thread, and the mounting base 4 is provided with a threaded hole that mates with the external thread.

[0036] As can be seen from the above description, the locking component 6 has a simple structure and is easy to disassemble and assemble.

[0037] Furthermore, it also includes an adjusting rod 7, which is threadedly engaged with the mounting base 4. The axial direction of the adjusting rod 7 is parallel to the second direction, and one end of the adjusting rod 7 is rotatably connected to the mounting block 5.

[0038] As described above, the relative positions of the camera 1 and the reflector 23 in the second direction can be finely adjusted by rotating the adjustment rod 7.

[0039] Furthermore, an anti-slip structure is provided on the outer peripheral surface of the end of the adjusting rod 7 away from the mounting block 5.

[0040] As can be seen from the above description, the anti-slip structure can increase friction, making it easier for workers to rotate the adjustment rod 7.

[0041] Furthermore, the translation drive mechanism 3 is a lead screw module.

[0042] Please refer to Figure 1 and Figure 2 One embodiment of this utility model is an image positioning device, including a camera 1 and a fixed base 2.

The end of the first optical channel 21 away from the second optical channel 22 is connected to the outer wall of the fixed base 2 to form a first window, and the end of the second optical channel 22 away from the first optical channel 21 is connected to the outer wall of the fixed base 2 to form a second window. A reflector 23 is provided at the connection between the first optical channel 21 and the second optical channel 22. The reflector 23 is used to reflect the light entering the first optical channel 21 into the second optical channel 22. The camera 1 is located outside the first window. In this embodiment, the extension direction of the first optical channel 21 is perpendicular to the extension direction of the second optical channel 22. The second optical channel 22 extends vertically, and the first optical channel 21 extends horizontally. The cross-sections of both the first optical channel 21 and the second optical channel 22 are rectangular.

[0043] The image positioning device further includes a translation drive mechanism 3, which drives the camera 1 to move closer to or further away from the mounting base 2 along a first direction parallel to the extension direction of the first optical channel 21. The translation drive mechanism 3 is a lead screw module.

[0044] The image positioning device further includes a mounting base 4, a mounting block 5, and a locking member 6. The mounting block 5 is mounted on the mounting base 4 and is movable relative to the mounting base 4 along a second direction, which is perpendicular to the first direction. The mounting base 4 is driven by a translation drive mechanism 3. The camera 1 is mounted on the mounting block 5. The locking member 6 is used to lock the relative positional relationship between the mounting base 4 and the mounting block 5. In this embodiment, the second direction is horizontal. Specifically, the mounting block 5 has an elongated hole 51, the length of which is parallel to the second direction. The locking member 6 passes through the elongated hole 51 and is detachably connected to the mounting base 4. The locking member 6 has an external thread, and the mounting base 4 has a threaded hole that mates with the external thread. There are multiple elongated holes 51, and each elongated hole 51 corresponds to a locking member 6.
