Description

Technical Field

[0001] The invention relates to an imaging device capable of adjusting the imaging focal length of an imaging device to improve the imaging quality. Background Art

[0002] Nowadays, electronic components are becoming increasingly small and precise. How to accurately align the contacts of electronic components with the probes of the test socket is indeed very important. At present, the test operation equipment is equipped with a test socket with probes on the machine, and the electronic component is moved to the top of the test socket by a crimper. An imaging device arranged on the side of the test socket uses a mobile platform to drive the imager to move horizontally at a fixed imaging operation height to between the electronic component and the test socket, so that the imager can capture the electronic component and the test socket, and determine whether the contacts of the electronic component and the probes of the test socket are aligned based on the image data. However, different types of electronic components require different test socket types and heights, but the mobile platform of the imaging device can only drive the imager to move horizontally, and the imager captures the test socket at a fixed imaging operation height, resulting in the imager's imaging focal length being unable to change to cope with test sockets of different heights, and the image is prone to being out of focus and blurred, which not only affects the image quality of the imager, but also makes it impossible to determine whether the contacts of the electronic component and the probes of the test socket are accurately aligned, thereby affecting the test quality.

DETAILED DESCRIPTION

[0046] In order to further understand the present invention, a preferred embodiment is given below with reference to the accompanying drawings.

[0047] See also Figure 1 , Figure 2 The imaging device 10 of the present invention includes a driving mechanism, a focusing mechanism and an imaging mechanism.

[0048] The driving mechanism is provided with at least one movable moving tool, and the moving tool is provided with a first transmission component; further, the driving mechanism drives the moving tool to move with a driving source, that is, the driving source drives the moving tool to move along the driving axis A, and the driving source can be a pressure cylinder, a motor, or a motor and a transmission group; the moving tool can be a block, a wedge block or a cam, and the first transmission component can be an inclined guide groove, a wedge surface, a cam surface or a roller, etc. The driving axis A can be a linear axis or a rotation axis, and is not limited to this embodiment.

[0049] In this embodiment, the driving source of the driving mechanism is configured in the form of a driving axis A in the X direction, including a motor 111 and a driving transmission group. The driving transmission group is a screw seat group 112. The screw seat of the screw seat group 112 is equipped with a moving tool 113. A first transmission component as an inclined guide groove 114 is opened inside the moving tool 113; in addition, at least one first slide rail group 115 configured in the form of the driving axis A is configured on the top surface of the moving tool 113 to assist in linear displacement.

[0050] The focusing mechanism is provided with a carrier having a second transmission component, and the second transmission component is driven by the first transmission component of the driving mechanism to move the carrier; further, the carrier is arranged in parallel with the moving device 113; the second transmission component can be a roller or an oblique guide groove, for example, the first transmission component is an oblique guide groove, and the second transmission component is a roller; conversely, the first transmission component is a roller, and the second transmission component is an oblique guide groove; in this embodiment, the carrier 121 is provided with a second transmission component, which is a roller 122, on the first surface 1211, and the roller 122 is embedded in the oblique guide groove 114 of the moving device 113.

[0051] Furthermore, a fixing frame 123 is provided on one side of the carrier 121, and the fixing frame 123, the carrier 121 and the moving device 113 are arranged in parallel, and a second slide rail group 124 is provided between the fixing frame 123 and the carrier 121 to assist the carrier 121 in linear displacement; in this embodiment, the fixing frame 123 is provided in front of the first surface 1211 of the carrier 121, and the fixing frame 123 is provided with a through hole 1231 for the roller 122 of the carrier 121 to pass through; however, the shape or size of the fixing frame 123 can also avoid the position of the roller 122, so there is no need to provide a through hole, which is not limited to this embodiment.

[0052] The imaging mechanism is equipped with at least one imaging device on the carrier 121 for imaging objects. The imaging device is driven by the carrier 121 to move to adjust the imaging focal length. Furthermore, the imaging device is equipped with at least one imaging portion according to the operation requirements to image at least one object. The imaging mechanism can be equipped with at least one imaging portion along the imaging axis B. More preferably, the imaging device can be equipped with a plurality of imaging portions, and the plurality of imaging portions capture a plurality of objects. The imaging portion can be a prism or a total reflection mirror. In this embodiment, the imaging mechanism is equipped with a CCD imaging device 131 on the second surface 1212 of the carrier 121, and is driven by the carrier 121 to move to different imaging heights. The imaging device 131 is equipped with a plurality of imaging portions along the imaging axis B. The plurality of imaging portions include a first imaging portion 1311 and a second imaging portion 1312 to respectively capture different objects (such as electronic components and test sockets).

[0053] However, the imager of the image capturing mechanism is installed at different angles according to the working requirements, and the image capturing part of the image capturing mechanism is installed at different angles according to the working requirements with the imager. In other words, it is sufficient to make the first image capturing part 1311 and the second image capturing part 1312 capture the object.

[0054] See also Figure 3The imaging device 10 of the present invention can be mounted on the machine 21 or the mobile platform 15. For example, the imaging device 10 is mounted on the machine 21 to image an object at a fixed point, or the imaging device 10 is mounted on the mobile platform 15 to image different objects at different positions. In this embodiment, the imaging device 10 is connected to the motor 111 of the driving mechanism, the fixing frame 123 of the focusing mechanism, the slide rail of the first slide rail group 115 and the mobile platform 15 by the connecting plate 14, so that the mobile platform 15 can drive the motor 111, the carrier 121 and the imager 131 to adjust the placement position in multiple directions through the connecting plate 14. In addition, a test seat 22 with a probe is set on the machine 21 for testing the electronic component 23, and a conveyor 24 is arranged above the test seat 22 for transferring the electronic component 23.

[0055] See also Figure 1 , Figure 4 When the conveyor 24 moves the electronic component 23 to the top of the test socket 22, the mobile platform 15 of the imaging device 10 drives the driving mechanism, the focusing mechanism and the imaging mechanism to move synchronously along the driving axis A with the connecting plate 14, so that the first imaging portion 1311 and the second imaging portion 1312 of the imaging mechanism are located between the electronic component 23 and the test socket 22, and the imaging device 131 is located at the first imaging height L1. The imaging device 131 uses the first imaging portion 1311 to image the electronic component 23 upward along the imaging axis B, and uses the second imaging portion 1312 to image the test socket 22 downward along the imaging axis B. The imaging device 131 transmits the electronic component image data and the test socket image data to a processor (not shown) for determining whether the contact of the electronic component 23 and the probe of the test socket 22 are accurately aligned, so that the conveyor 24 can accurately move the electronic component 23 into the test socket 22 to perform the test operation.

[0056] See also Figure 1 , Figure 5 , Figure 6 When taking images of different electronic components 23A, the imaging mechanism can cooperate with the conveyor 24 to move in the Z direction to adjust the transfer height of the electronic component 23A to match the imaging focal length of the imager 131; however, since different types of test sockets 22A have different volume heights, under the condition that the test socket 22A is fixed on the machine platform 21, the imaging focal length of the imager 131 for the test socket 22A must also be changed in order to clearly image the test socket 22A.

[0057] When the machine 21 is equipped with a different type of test seat 22A, the motor 111 of the imaging device 10 drives the moving device 113 to move along the driving axis A through the screw seat of the screw seat assembly 112. The moving device 113 pushes the roller 122 of the carrier 121 with the inclined guide groove 114 and moves downward. The roller 122 drives the carrier 121 to move synchronously. The carrier 121 uses the second slide rail assembly 124 to linearly move downward along the imaging axis B in the Z direction to drive the imager 131, the first imaging portion 1311 and the second imaging portion 1312 to move downward synchronously. The imager 131 is adjusted from the first imaging height L1 to the position of The second imaging height L2 is used to adjust the imaging focal length of the first imaging portion 1311 to the electronic component 23A, and to adjust the imaging focal length of the second imaging portion 1312 to the test socket 22A, so that the imager 131 cooperates with the first imaging portion 1311 and the second imaging portion 1312 to clearly image the electronic component 23A and the test socket 22A, respectively, so that the processor (not shown) can accurately determine whether the contacts of the electronic component 23A and the probes of the test socket 22A are accurately aligned based on the clear electronic component image data and the test socket image data, so that the conveyor 24 can accurately move the electronic component 23A into the test socket 22A to perform the test operation.
