Description

Technical Field

[0001] This utility model relates to the field of wire bonding machine technology, and in particular to a large field-of-view zoom lens. Background Technology

[0002] Wire bonding machines, including gold wire bonding machines, aluminum wire bonding machines, and ultrasonic wire bonding machines, are used to achieve surface bonding of different media, which is a physical change process. During the process of capturing images of wire-bonded chips, the bonding speed of the wire bonding machine is extremely fast, and the lens needs to handle chips of various shapes while simultaneously performing chip identification.

[0003] Therefore, how to quickly, stably, efficiently, and accurately identify chips of different heights and with multiple groups during high-speed movement has always been a major challenge in the industry; however, existing wire bonding machine lenses cannot solve this problem.

[0004] Therefore, it is necessary to design a zoom lens with a large field of view to solve the above problems. Utility Model Content

[0005] This invention provides a wide field-of-view zoom lens capable of quickly, stably, efficiently, and accurately identifying chips of different heights and numbers of groups.

[0006] The technical solution adopted by this utility model is as follows: a large field of view zoom lens, which includes: a lens body, a camera and a light module; the lens body is provided with an optical module, the camera is installed at the rear end of the lens body, the light module is installed at the front end of the lens body, and the optical module connects the camera and the light module.

[0007] The lens body is composed of a thin plate in the shape of an "I". The lens body has an optical channel inside, and the optical module is installed in the optical channel. The rear end of the lens body has a mounting position, which is connected to the optical channel. The camera is fixed to the mounting position by a fixing component. The optical module includes an objective lens, which is located at the front end of the lens body and close to the light module. The objective lens has a larger outer diameter (compared to previous wire bonding machine lenses).

[0008] Furthermore, the fixing assembly includes an upper clamp, a left clamp, and a right clamp; the upper clamp is clamped on the top of the camera's adapter ring, and both ends of the upper clamp are fixed to the rear end of the lens body; one end of the left clamp is clamped to the left side wall of the camera, and the other end is fixed to the rear end of the lens body; one end of the right clamp is clamped to the right side wall of the camera, and the other end is fixed to the rear end of the lens body.

[0009] Furthermore, a heat dissipation module is provided at the bottom of the lens body.

[0010] Furthermore, the lighting module includes a main light source and a side light source; the main light source is located above the objective lens, and the side light source is located outside the objective lens.

[0011] Furthermore, the upper clamping member is an arc-shaped clamping member.

[0012] Compared to existing technologies, this invention's large field-of-view zoom lens, by constructing the lens body from an I-shaped thin plate, makes the entire large field-of-view zoom lens lighter and stronger, thus enabling accurate chip identification. Furthermore, by designing a larger outer diameter for the objective lens, the camera can simultaneously identify multiple chip groups when recognizing chip materials, improving recognition efficiency. At the same time, the increased outer diameter of the objective lens allows more light to enter the entire imaging system, thereby improving image clarity. Attached Figure Description

They are used together with the following detailed description to explain the present invention, but should not be construed as limiting the present invention. In the drawings,

[0015] Figure 2 : An exploded perspective view of the large field-of-view zoom lens of this utility model. Detailed Implementation

[0016] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0017] like Figure 1 and Figure 2 As shown, the large field-of-view zoom lens of this utility model includes a lens body 1, a camera 2, and a lighting module 3; wherein, the lens body 1 is provided with an optical module, the camera 2 is installed at the rear end of the lens body 1, the lighting module 3 is installed at the front end of the lens body 1, and the optical module connects the camera 2 and the lighting module 3.

[0018] Specifically, the lens body 1 is composed of thin "I"-shaped plates, making the entire wide field-of-view zoom lens lighter and stronger, thus enabling accurate chip identification. Furthermore, the lens body 1 has an internal optical channel, within which the optical module is installed.

[0019] The rear end of the lens body 1 is provided with a mounting position 4, which communicates with the optical channel. The camera 2 is mounted on the mounting position 4. Specifically, the camera 2 is fixed to the mounting position 4 by a fixing component. The fixing component includes an upper clamping member 5, a left clamping member 6, and a right clamping member 7. The upper clamping member 5 is an arc-shaped clamping member that clamps the top of the adapter ring 201 of the camera 2, and both ends of the upper clamping member 5 are fixed to the rear end of the lens body 1. One end of the left clamping member 6 is clamped to the left side wall of the camera 2, and the other end is fixed to the rear end of the lens body 1. One end of the right clamping member 7 is clamped to the right side wall of the camera 2, and the other end is fixed to the rear end of the lens body 1.

[0020] The camera 2 is fixed by setting the upper clamping part 5, the left clamping part 6 and the right clamping part 7, so that the camera 2 can be fixed in multiple directions. This ensures the stability of the entire large field of view zoom lens structure under the high-speed movement of the wire bonding machine, and enables the camera 2 to accurately identify the chip.

[0021] The optical module includes an objective lens 8, which is located at the front end of the lens body 1, close to the light module 3. The objective lens 8 has a larger outer diameter than the previous wire bonding machine lens design. By designing the outer diameter of the objective lens 8 to be large, the camera 2 can identify multiple sets of chips at the same time when identifying chip materials, thus improving the identification efficiency. At the same time, due to the increase in the outer diameter of the objective lens 8, more light can enter the entire imaging system, thereby improving the image clarity.

[0022] In addition, a heat dissipation module 9 is provided at the bottom of the lens body 1 to dissipate heat from the entire lens body 1. The lighting module 3 includes a main light source 301 and a side light source 302; wherein, the main light source 301 is located above the objective lens 8, and the side light source 302 is located outside the objective lens 8.

[0023] In summary, the wide field-of-view zoom lens of this invention has the following advantages:

[0024] 1. By setting the lens body 1 to be composed of I-shaped thin plates, the entire wide field-of-view zoom lens is made lighter and stronger, thereby enabling accurate identification of the chip.

[0025] 2. By designing the outer diameter of objective lens 8 to be larger, camera 2 can identify multiple sets of chips simultaneously when identifying chip materials, thus improving the identification efficiency; at the same time, due to the increase in the outer diameter of objective lens 8, more light can enter the entire imaging system, thereby improving the clarity of the image.

[0026] 3. By setting the upper clamping part 5, the left clamping part 6 and the right clamping part 7 to fix the camera 2, the camera 2 can be fixed in multiple directions, ensuring the stability of the entire large field of view zoom lens structure under the high-speed movement of the wire bonding machine, so that the camera 2 can accurately identify the chip.

[0027] 4. A heat dissipation module 9 is also provided at the bottom of the lens body 1 to dissipate heat from the entire lens body 1.

[0028] 5. By eliminating the zoom function in the optical module, the number of lenses in the optical module is reduced, the optical path is shorter, the overall weight of the device can be made lighter, the machine can run faster, and the recognition efficiency is improved.
