Description

Equipment used to press against electronic components

The present invention provides a device for pushing against an electronic component, and particularly relates to a device for pushing against an electronic component that can reduce the relative error between the pushing position and the detection position.

Diode panel display is one of the mainstream display devices currently on the market. Generally speaking, the production process of diode panel products requires processes such as epitaxy, mass transfer, and die bonding. In the process of mass transfer, the light-emitting diodes will be arranged on the target panel or substrate through micro-electromechanical array technology, and the arranged light-emitting diodes will be fixed on the target panel or substrate through fixing methods such as solder. This allows the panel to have a high-density arrangement of light-emitting diodes. When powered, each light-emitting diode emits light of different colors, thereby providing a highly saturated visual experience.

However, during the transfer process, some diode wafers may themselves have defects. Therefore, the wafer to be transferred needs to be inspected before transfer, for example, by contacting the wafer to be inspected with a conductive probe. To test whether these wafers can emit light normally, or when the wafers are placed in the correct position, it is necessary to press the wafers against specific positions on the target substrate through components and process them at the same time. However, in the prior art, the image capturing device used to detect the above-mentioned position and the pushing device that actually performs the pushing action are independent mechanisms and have their own positioning coordinate systems. Therefore, when the pushing device captures images based on a fixed When the positioning information of the device moves, it is easy to increase the probability of detection failure or decrease the product yield due to the position deviation generated during the movement. And when the device needs to be moved multiple times, the above deviations will gradually accumulate and cause This phenomenon is more obvious. In addition, when the coordinate system of the pushing device is different from the coordinate system of the image capturing device, even after multiple corrections or compensations, it is still difficult to position the pushing device to the correct detected position, so it is difficult for inspection or processing. processes are severely affected.

The inventor then devoted his mind to research and developed a device for pushing against electronic components that can reduce the relative error between the pushing position and the detection position, in order to improve the detection accuracy and product yield.

The invention provides a device for resisting electronic components, including a carrier, a resisting component and an image capturing component. The carrier is used to carry a flexible carrier, and an electronic component is disposed on the flexible carrier; the resisting component is disposed adjacent to the carrier and is adapted to be driven by an actuating mechanism to perform a resisting action toward the carrier; image capture The retrieval component is used to retrieve the position of the electronic component and generate a position information. In addition, the relative positions of the resisting element and the image capturing element are fixed in a horizontal direction parallel to the carrier, and the resisting element performs a resisting action toward the carrier according to the position information.

In one embodiment, the above-mentioned resisting element and image capturing element are jointly arranged on a bracket.

In one embodiment, the above-mentioned resisting element and the image capturing element are adapted to move synchronously in the horizontal direction.

In one embodiment, the above-mentioned resisting element is light-transmissive.

In one embodiment, the device for resisting electronic components further includes an energy generating device, and the energy generating device is used to generate an energy beam directed toward the carrier.

In one embodiment, the above-mentioned resisting element is light-transmissive, and the energy beam passes through the resisting element and is directed to the carrier.

In one embodiment, the energy generating device is a laser generator.

Thereby, in the device for resisting electronic components of the present invention, since the relative positions of the resisting component and the image capturing component are fixed in the horizontal direction, the resisting component and the image capturing component can share the same positioning coordinate system and position. information to reduce errors generated during positioning, thereby improving detection accuracy and product yield.

In order to make the above-mentioned features and advantages of the present invention more obvious and easy to understand, embodiments are given below and described in detail with reference to the accompanying drawings.

The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the preferred embodiments with reference to the drawings. It is worth mentioning that the directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only for reference to the directions in the attached drawings. Accordingly, the directional terms used are illustrative rather than limiting. In addition, in the following embodiments, the same or similar elements will use the same or similar reference numerals.

Please refer to Figures 1 and 2. Figure 1 is a schematic side view of an embodiment of a device for resisting electronic components according to the present invention, and Figure 2 is an implementation of a device for resisting electronic components according to the present invention. A side view of an example when it is pressed against an electronic component. The device 1 for pressing against an electronic component in this embodiment is suitable for pressing against an electronic component 2 and includes a carrying frame 100, a pressing element 200 and an image capturing element 300, wherein the carrying frame 100 is used to carry an The flexible carrier 3 is provided with an electronic component 2 on the flexible carrier 3. The resisting component 200 is disposed adjacent to the carrier 100, and the image capturing component 300 is used to capture the position of the electronic component 2.

In detail, the carrier 100 is, for example, a carrier frame, and the flexible carrier 3 is, for example, a blue film. Thereby, the electronic component 2 can be attached to the flexible carrier 3 and held by the carrier 100 to perform processes such as processing or inspection, and then transferred to the substrate 4 in FIG. 1 .

As shown in FIG. 1 , the pushing element 200 is, for example, an ejector pin, and is adapted to be driven by an actuating mechanism 5 to perform a pushing action toward the carrier. Specifically, the actuating mechanism 5 may include a horizontal actuating mechanism 52 and a pushing actuating mechanism 54, where the horizontal actuating mechanism 52 and the pushing actuating mechanism 54 are, for example, servo motors, voice coil motors or stepper motors. , can be used to selectively drive the resisting element 200 to move in a horizontal direction H or to perform a resisting action toward the carrier 100 , and the method of resisting the carrier 100 is, for example, to separately displace the resisting element 200 Thereby, the electronic component 2 on the flexible carrier 3 is contacted, or the mechanism arranged to abut the component 200 is directly driven to move the entire body toward the carrier 100 , which is not limited by the present invention.

On the other hand, the image capturing element 300 includes, for example, a charge coupled device (CCD), which can capture the position of the electronic component 2 on the carrier 100 to generate position information. Preferably, the device 1 for resisting electronic components also includes a control unit (not shown), where the control unit is, for example, an industrial computer or a programmable logic controller (PLC), and the resisting component 200, The image capturing element 300 and the actuating mechanism 5 are electrically connected to the control unit. Thereby, the image capturing element 300 can transmit the captured position of the electronic component 2 and the generated position information to the control unit, and the control unit can control the displacement of the resisting element 200 or drive the resisting element 200 through the actuating mechanism 5 for execution. The pushing action allows the originally independent components to work together.

In order to overcome the errors caused by the relative displacement of the previous resisting devices and the image capturing devices, the relative positions of the resisting element 200 and the image capturing element 300 in this embodiment are fixed in the horizontal direction H parallel to the carrier 100, and The resisting element 200 performs a resisting action toward the carrier 100 based on the position information generated by the image capturing element 300 . In detail, the device 1 for resisting electronic components may further include a bracket 400 , and the resisting element 200 and the image capturing element 300 are jointly arranged on the bracket 400 . Therefore, when the bracket 400 moves, the resisting element 200 and the image capturing element 300 are adapted to move synchronously in the horizontal direction H, so that the resisting element 200 does not cause positioning errors due to movement. The above-mentioned synchronous movement means that the resisting element 200 and the image capturing element 300 have the same amount of movement at the same point in time, and their relative positions remain constant. However, according to the time difference in signal transmission, the resisting element 200 and the image capturing element 300 move at the same time. There may be a delay of several milliseconds to tens of milliseconds between the actions of the component 300, which is still within the allowable range of the present invention. Preferably, the coordinate system used by the resisting element 200 to move and the coordinate system used by the image capturing element 300 are the same coordinate system. In this way, even if the resisting element 200 performs multiple movements or resisting, the resisting element 200 will not move. The position error between the image capturing element 300 and the image capturing element 300 will not continue to accumulate, which can improve the accuracy of detection or processing.

In other possible embodiments, the resisting element 200 and the image capturing element 300 may not be connected to each other through the bracket 400, but they may be directly integrated into the same mechanical component. For example, the image capturing element 300 can be directly disposed on the resisting element 200, or can be coaxially disposed with the resisting element 200 in a direction perpendicular to the carrier 100, and the combination method can include fitting, gluing, and locking. Or welding, which can achieve the same effect.

In a possible embodiment, the device 1 for resisting electronic components further includes an energy generating device 500 , where the energy generating device 500 is, for example, a laser generator and is installed above the resisting component 200 . Specifically, the energy generating device 500 of this embodiment can be directly disposed on the bracket 400 or the mechanism mounted on the resisting element 200 , or it can be kept at an appropriate distance from the bracket 400 , and the energy generating device 500 can generate energy directed toward the carrier 100 The energy beam 510 is used to detect or process the electronic component 2.

Preferably, the resisting element 200 is made of a light-transmitting material and can be light-transmissive. Specifically, the resisting element 200 can be made of glass, quartz, diamond, or other materials, and the energy beam 510 can be emitted to the carrier 100 through the resisting element 200 . Through such a configuration, when the image capturing element 300 detects that the electronic component 2 is in the correct position, the control unit can drive the actuating mechanism 5 so that the actuating mechanism 5 further drives the resisting element 200 to resist in the direction of the carrier 100 The electronic component 2 is temporarily fixed to the surface of the carrier 100 or the flexible carrier 3 . After that, the energy generating device 500 can generate the energy beam 510 and adjust the energy beam 510 so that it passes through the resisting element 200 and shoots towards the electronic component 2 on the flexible carrier 3, whereby the electronic component can be fixed and processed while resisting. 2. Greatly improve processing efficiency.
