Description

[Technical Field]

[0001] This utility model relates to an automatic conductive adhesive adjustment device that can automatically adjust conductive adhesive without removing the fixing components. [Background Technology]

[0002] An integrated circuit (IC) test sorter primarily uses a test connector (IC Test Socket) containing a contact module to provide a medium for transmitting test signals from an IC chip under test. The test connector is mounted on an IC Test LoadBoard of the test sorter. The contact module has multiple electrical connection contacts for electrically connecting the IC chip under test and the test loadboard, respectively. The contact module can be, for example, a card-type or sheet-type probe assembly, a wire-type conductive film, or a gold powder-type conductive film. The wire-type conductive film and the gold powder-type conductive film are elastic.

[0003] In the current testing situation, when there are production yield problems or electrical performance issues at the same point on an integrated circuit, it is necessary to adjust the conductive adhesive. This is because the conductive adhesive may have some dirt or have been used for too long, resulting in poor electrical test results. Therefore, it is necessary to move the conductive adhesive to improve the effectiveness of electrical tests. However, the current process of moving conductive adhesive is mostly done manually, meaning that the fixing components must be manually disassembled to adjust the conductive adhesive. The biggest problem with manual adjustment is that since the test openings are mostly only 2mm to 3mm, it is difficult to control the accuracy of the conductive adhesive movement distance manually. Because the distance may be different at each point when manually controlled, this will introduce errors.

[0004] How to solve the above problems and deficiencies is the direction that the applicant of this utility model and related manufacturers in this industry urgently want to study and improve. [Utility Model Content]

[0005] The main objective of this invention is to provide a method in which a pressing component of a pressing device can directly fix and limit the conductive adhesive. When it is necessary to move the conductive adhesive, the pressing component can be driven to move away from the conductive adhesive, allowing the conductive adhesive to be in a free state. The conductive adhesive can then be moved by an adjustment device, thus achieving the goal of moving the conductive adhesive without disassembling the fixing components. This makes the process of moving the conductive adhesive more convenient, faster, and more user-friendly.

[0006] Another important aspect of this invention is the interconnected design of the automatic control device. Through the interconnected information of the detection device, the automatic control device, the pressing device, and the adjustment device, when the detection device determines that the electronic component on the test board does not meet expectations, the automatic control device can control the pressing device and the adjustment device to operate, thereby achieving the function of automatically adjusting the position of the conductive adhesive and improving the yield of the electronic component.

[0007] The structure of this utility model that achieves the above-mentioned main objectives includes a carrier, a test plate, a fixing component, a detection component, a channel, several pressing devices, a pressing component, an adjustment device, a base assembly, a fixing component, and an automatic control device. The test plate is disposed on the carrier, the fixing component is disposed above the test plate, the fixing component has a channel for the detection component to pass through, and a pressing device is disposed on one side of the fixing component. Each pressing device has a pressing component that can contact conductive adhesive. An adjustment device is disposed on one side of the carrier, the adjustment device includes a base assembly and a fixing component, and the pressing device, the adjustment device, and the detection component are linked to the automatic control device.

[0008] When the testing component tests the electronic components on the test board, it detects them through the channel on the fixing component. When the testing component detects the electronic components on the test board and determines that they do not meet expectations, it sends a detection signal to the automatic control device. After receiving the detection signal, the automatic control device generates a control command to the pressing device and the adjustment device. This allows the adjustment device to move the conductive adhesive by using the base assembly to drive the fixing component after each pressing component leaves the conductive adhesive, thereby achieving automatic adjustment of the conductive adhesive's position.

[0009] By employing the above-mentioned technology, the existing engineering methods for moving conductive adhesives, which are mostly manual, can be addressed. This means that the fixing components must be manually disassembled to adjust the conductive adhesive. The biggest problem with manual adjustment is that the detection openings are mostly only 2mm to 3mm wide, making it difficult to control the accuracy of the conductive adhesive's movement distance manually. Because the distance at each point may be different during manual control, this technology overcomes the problem of error and achieves the practical and progressive advantages of this utility model.

Detailed Implementation Methods

[0011] Please see Figures 1 to 4 The image shown is a perspective view of the first preferred embodiment of the present invention, illustrating its movement. Figure 3 As can be clearly seen from the figure, this utility model includes:

[0012] A support component 1 is provided for mounting a test plate 6;

[0013] A fixing component 2 is disposed above the test plate 6, and the fixing component 2 has a channel 21 for a test piece 7 to pass through;

[0014] Several pressing devices 3 are respectively located on one side of the fixing component 2. Each pressing device 3 has a pressing part 31 that can contact a conductive adhesive 8. The conductive adhesive 8 is located on the test plate 6.

[0015] An adjustment device 4 is disposed on one side of the support member 1. The adjustment device 4 includes a movable base assembly 41 and a fixing member 42 disposed at the front end of the base assembly 41 for engaging one end of the conductive adhesive 8; and

[0016] An automatic control device 5 is linked to the pressing device 3, the adjusting device 4 and the detection element 7, so that when it receives the detection signal from the detection element 7, it determines whether to control the pressing device 3 and the adjusting device 4 to operate based on the detection signal.

[0017] The support component 1 is a platform. The test board 6 has an electronic component 61 (a chip) at its center. The fixing component 2 is made of engineering plastic and is used to limit the conductive adhesive 8. The detection component 7 is a detection head. The pressing device 3 has a pressing arm 32 for setting the pressing component 31, a pressing seat 33 located at the end of the pressing arm 32 away from the pressing component 31, and a lifting device 34 for setting the pressing seat 33. The lifting device 34 can be hydraulic, pneumatic, or electric driven. The adjusting device 4 can be a telescopic rod pneumatic cylinder, a telescopic rod hydraulic cylinder, or a mechanical structure composed of gears, racks, and rails. This embodiment uses a telescopic rod pneumatic cylinder as an example. The automatic control device 5 is a computer.

[0018] When the detection component 7 detects a production yield problem or an electrical non-compliance issue at the same point on the electronic component 61, the detection component 7 will send a detection signal to the automatic control device 5. Upon receiving the detection signal, the automatic control device 5 will generate a control command for the pressing device 3 and the adjustment device 4. At this time, the pressing device 3 will... Figure 2 As shown, after the lifting device 34 slowly raises the pressing seat 33, the pressing arm 32 and the pressing component 31 rise accordingly. At this time, the pressing component 31 separates from the conductive adhesive 8, and the conductive adhesive 8 becomes free (meaning that the conductive adhesive 8 is no longer restrained and can move). When the conductive adhesive 8 becomes free, the adjusting device 4 uses the base assembly 41 to drive the fixing component 42, allowing the fixing component 42 to pull the conductive adhesive 8 and make a slight displacement, such as... Figure 3 As shown; and after completing the movement, the pressing device 3 descends to re-press the conductive adhesive 8, and simultaneously the detection component 7 descends and enters channel 21 to begin detection, as shown. Figure 4As shown, this allows the conductive adhesive 8 to be moved without disassembling the fixing component 2, making the process of moving the conductive adhesive 8 more convenient, faster, and more user-friendly. In particular, through the linkage design of the automatic control device 5, the position of the conductive adhesive 8 can be automatically adjusted, thereby improving the yield of electronic components 61.

[0019] Please see Figures 5 to 9 The image shown is a perspective view of the second preferred embodiment of the present invention, illustrating its movement. Figure 3 As can be clearly seen from the figure, the difference between this embodiment and the above embodiment is that the fixing component 2 in this embodiment has several through holes 22 respectively located on one side of the channel 21. Each through hole 22 allows each pressing component 31 to pass through and press the conductive adhesive 8. The base assembly 41 also has a forearm 411 for mounting the fixing component 42 and at least one movable arm 412 located on one side of the forearm 411. The movable arm 412 can drive the forearm 411 to move. In this embodiment, several movable arms 412 are used as an example, and they are connected to each other by rails. The movable arms 412 are driven to move back and forth by a motor. In addition, the fixing component 2 has a fixing channel 23 on the side facing the conductive adhesive 8. The fixing channel 23 is a groove to allow the conductive adhesive 8 to pass through the fixing component 2 and to limit its position, preventing the conductive adhesive 8 from being mispositioned.

[0020] For the automatic adjustment process of conductive adhesive 8, the detection component 7 can first detect the electronic component 61 in the test plate 6 set on the carrier 1, and the conductive adhesive 8 on the test plate 6 is pressed and fixed by the pressing component 31 on the pressing device 3; then the detection component 7 detects the electronic component 61 on the test plate 6. When it is determined that it meets the expectations, no detection signal is sent. If it is determined that it does not meet the expectations, a detection signal is sent to the automatic control device 5; after receiving the detection signal, the automatic control device 5 generates a control command to the pressing device 3 and the adjustment device 4, so that after each pressing component 31 leaves the conductive adhesive 8, the adjustment device 4 uses the base assembly 41 to drive the fixing component 42 that fixes the conductive adhesive 8 to move the conductive adhesive 8, so as to automatically adjust the position of the conductive adhesive 8.

[0021] When the detection component 7 detects a production yield problem or an electrical non-compliance issue at the same point on the electronic component 61, the detection component 7 will send a detection signal to the automatic control device 5. Upon receiving the detection signal, the automatic control device 5 will generate a control command for the pressing device 3 and the adjustment device 4. At this time, the pressing device 3 will... Figure 7As shown, after the lifting device 34 slowly raises the pressing seat 33, the pressing arm 32 raises the pressing component 31 accordingly. At this time, the pressing component 31 leaves the conductive adhesive 8 and detaches from the fixing component 2 at the through hole 22. The conductive adhesive 8 is then freed from the restraint of the pressing component 31 and becomes free. When the conductive adhesive 8 becomes free, the multiple movable arms 412 of the adjusting device 4 begin to move in conjunction with the motor, allowing the front arm 411 to move backward, thereby pulling the conductive adhesive 8 backward within the fixed channel 23. Figure 8 As shown; after the conductive adhesive 8 has completed its movement, the pressing component 31, driven by the lifting device 34, descends again, passes through the perforation 22, and re-presses the conductive adhesive 8. Then, the detection component 7 descends and enters the channel 21 to begin detection, as shown. Figure 9 As shown.

[0022] The key improvement of the conductive adhesive automatic adjustment device of this utility model lies in:

[0023] First, the conductive adhesive 8 is directly fixed and limited by the pressing component 31 of the pressing device 3. When it is necessary to move the conductive adhesive 8, the pressing component 31 can be driven to move away from the conductive adhesive 8, so that the conductive adhesive 8 is in a free state. The conductive adhesive 8 can be moved by the adjusting device 4, so that the conductive adhesive 8 can be moved without the need for manual disassembly of the fixing component 2. This eliminates the risk caused by manual disassembly and makes the process of moving the conductive adhesive 8 more convenient, faster and more user-friendly.

[0024] Secondly, through the interconnected information relationship between the testing component 7, the automatic control device 5, the pressing device 3, and the adjustment device 4, when the testing component 7 determines that the electronic component 61 on the test board 6 does not meet expectations, the automatic control device 5 can control the pressing device 3 and the adjustment device 4 to operate, thereby achieving the function of automatically adjusting the position of the conductive adhesive 8 and accurately controlling the moving distance of the conductive adhesive 8, thereby improving the yield of the electronic component 61 and improving industrial efficiency.

[0025] Third, through the design of the perforation 22, the pressing component 31 can press the conductive adhesive 8 in the shortest stroke, so as to achieve more precise fixation of the conductive adhesive 8 and make the conductive adhesive 8 less prone to displacement problems.

[0026] Fourth, through the design of the pressing arm 32, the pressing seat 33 and the lifting device 34, the pressing component 31 can be lifted and lowered automatically according to the instructions of the automatic control device 5, without the need for manual operation, which is extremely convenient and competitive in the industry.

[0027] Fifth, through the design of the forearm 411 and the movable arm 412, the fixing member 42 has the function of forward and backward displacement, thus achieving the advantage of automatically adjusting the conductive adhesive 8.

[0028] Sixth, the design of the fixed channel 23 ensures that the conductive adhesive 8 will not drift or move, effectively limiting its position and improving the accuracy of detection.
