Description

Technical Field

[0001] This utility model belongs to the field of rapid positioning technology for chip testing, and specifically relates to a rapid bonding automatic testing device. Background Technology

[0002] In the field of electronic chip testing, a fast and reliable connection between the testing equipment and the PCB board is crucial for ensuring testing efficiency and accuracy. Traditional testing equipment typically uses manual alignment and fixing methods to achieve signal connection. For example, the test substrate is manually aligned with the PCB board and then fixed with screws or other fasteners, relying on rigid connectors for signal transmission. However, this method suffers from low positioning efficiency and insufficient accuracy.

[0003] In other words, manual alignment relies on the operator's experience and skills, making it difficult to achieve high-precision positioning. This can easily lead to signal transmission channel misalignment or poor contact, affecting the reliability of test results. The inefficiency of manual operation is particularly prominent in batch testing scenarios that require frequent PCB board replacements. Utility Model Content

[0004] This utility model addresses the problems of existing technologies by providing a rapid bonding automatic testing device, the specific technical solution of which is as follows:

[0005] A rapid bonding automatic testing device includes a substrate, a connector base, and a PCB board. The connector base is disposed between the substrate and the PCB board to form a signal transmission channel. A guide hole is formed on the substrate. A guide post is installed on the connector base. A threaded groove is formed in the guide hole to form a threaded hole. The middle section of the guide post has an external thread. An output motor is also installed on the connector base. The output end of the output motor is connected to the end of the guide post and drives it to rotate.

[0006] In the installed state, the guide post is inserted into the guide hole and screwed in.

[0007] As a further technical solution of this utility model, a signal transmission component is installed in the connector base, and a solder pad is installed on the mating surface of the substrate. In the installed state, the signal transmission component is in contact with the solder pad, and the guide post and the guide hole are screwed together before the signal transmission component and the solder pad come into contact.

[0008] As a further technical solution of this utility model, at least two sets of guide holes are provided, and the guide posts and guide holes are matched accordingly.

[0009] As a further technical solution of this utility model, the PCB board is provided with mounting holes, and the end of the signal transmission component is inserted into the mounting holes in the installation state.

[0010] As a further technical solution of this utility model, the connector base has a mounting groove at its tail, and the PCB board is inserted into the mounting groove in the installation state.

[0011] As a further technical solution of this utility model, the end insertion part of the signal transmission component includes a pin, the middle of the pin extends radially to both sides to form an arched protrusion, and a fisheye is formed between the two sets of arched protrusions to allow the arched protrusions to deform. In the installed state, the arched protrusions are inserted into the mounting hole and deform.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) Automatic rapid positioning and connection technology;

[0014] By setting guide holes with threaded holes on the substrate and guide posts with external threads on the connector base, and driving the guide posts to rotate via an output motor, automatic screw-in positioning of the substrate and connector base is achieved. This design transforms manual operation into a motor-driven automated process, significantly improving installation efficiency and positioning accuracy.

[0015] Furthermore, at least two sets of guide holes and guide posts are provided and matched accordingly. Through the principle of multi-point positioning, the stability and reliability of the connection are further improved, and the offset problem that may occur in single-point positioning is avoided.

[0016] (2) Optimization of signal contact reliability;

[0017] By controlling the guide post and guide hole to complete the screw connection before the signal transmission component and solder pad come into contact, it is ensured that the mechanical positioning is accurately completed before the electrical connection, thereby avoiding signal contact failure caused by mechanical displacement.

[0018] The pins at the end of the signal transmission component are designed with arched protrusions and a fisheye structure. When the arched protrusions are inserted into the mounting holes on the PCB board, elastic contact pressure is generated through deformation, forming a tight electrical connection. This elastic contact structure can accommodate a certain range of installation errors, while the deformation space design of the fisheye structure ensures contact stability during long-term use, solving the problem of loosening that is common with traditional rigid connectors.

[0019] (3) Modular quick-installation structure;

[0020] The connector base features a mounting slot at its rear, allowing the PCB board to be directly inserted into it. Combined with the plug-in design of the signal transmission components, this enables rapid positioning and installation of the PCB board. This modular design simplifies the assembly process, facilitates the replacement of PCB boards of different specifications, and improves the versatility and maintainability of the device.

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] Figure 1 A schematic diagram of the overall structure of the rapid bonding automatic testing device is shown. Figure 2 A disassembled structural diagram of the substrate 100 and the connector base 200 is shown; Figure 3 A schematic diagram of the mating structure between the connector base 200 and the PCB board 300 is shown. Figure 4 A schematic diagram of the signal transmission device 230 is shown.

[0029] Figure 1 The rapid bonding automatic testing device includes a substrate 100, a connector base 200, and a PCB board 300. The connector base 200 is disposed between the substrate 100 and the PCB board 300 to form a signal transmission channel. In other words, the connector base 200 is used to realize the signal path between the substrate 100 and the PCB board 300 to achieve chip testing.

[0030] Figure 2In the process, a guide hole 110 is provided on the substrate 100, and a guide post 210 is installed on the connector base 200. In the installed state, the guide post 210 is inserted into the guide hole 110. Through the docking of the guide post 210 and the guide hole 110, the substrate 100 and the connector base 200 are quickly positioned and connected. At least two sets of guide holes 110 are provided, and the guide posts 210 and guide holes 110 are matched accordingly. That is to say, the number of guide posts 210 is the same as the number of guide holes 110, and they correspond one-to-one to achieve multi-point positioning.

[0031] A threaded groove is provided in the guide hole 110 to form a threaded hole, and the middle section of the guide post 210 has an external thread; that is, as the guide post 210 and the guide hole 110 are connected, the head of the guide post 210 first passes through the guide hole 110, and then the middle section of the guide post 210 rotates into the guide hole 110 to realize the screw connection between the two.

[0032] An output motor 220 is also installed on the connector base 200. The output end of the output motor 220 is connected to the end of the guide post 210 and drives it to rotate. With the setting of the output motor 220, the guide post 210 can be driven to rotate when it enters the guide hole 110 in the middle section to achieve screw connection.

[0033] A signal transmission component 230 is installed inside the connector base 200, and a solder pad 120 is installed on the mating surface of the substrate 100. In the installed state, the signal transmission component 230 is in contact with the solder pad 120, and the guide post 210 and the guide hole 110 are screwed together before the signal transmission component 230 and the solder pad 120 are in contact. That is, after the solder pad 120 and the signal transmission component 230 are in contact, the guide post 210 and the guide hole 110 are screwed together to ensure stable contact.

[0034] Figure 3 In the middle, the connector base 200 has a mounting groove 240 at the tail, and the PCB board 300 is inserted into the mounting groove 240 in the installation state; the mounting groove 240 is used to match the shape of the PCB board 300 to realize the quick docking of the connector base 200 and the PCB board 300.

[0035] The PCB board 300 has mounting holes 310. The end of the signal transmission component 230 is inserted into the mounting hole 310 in the installed state. That is, the end of the signal transmission component 230 is inserted into the mounting groove 240. After the PCB board 300 is installed according to the shape trajectory of the mounting groove 240, the signal transmission component 230 can be inserted into the mounting hole 310 to achieve plug-in.

[0036] Figure 4In the signal transmission component 230, the end insertion portion includes a pin 231. The middle of the pin 231 extends radially to both sides to form an arched protrusion 232. Between the two sets of arched protrusions 232, a fisheye 233 is formed to allow the arched protrusions 232 to deform. In the installed state, the arched protrusions 232 are inserted into the mounting hole 310 and deform. That is, the distance between the two arched protrusions 232 is greater than the diameter of the mounting hole 310, and the fisheye 233 provides space for the deformation of the arched protrusions 232. When the arched protrusions 232 are inserted into the mounting hole 310 and deform, they squeeze the internal space of the fisheye 233, forcing a certain contact pressure between the arched protrusions 232 and the inner wall of the mounting hole 310.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
