Therefore, improving the installation quality of circuit boards is the technical problem this application aims to solve. Utility Model Content

[0030] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0031] The following is for reference. Figures 1-2 This application describes a testing fixture 100 for circuit board mounting according to an embodiment of the present application.

[0032] A testing fixture 100 for circuit board mounting according to an embodiment of this application includes a first mounting base 1, a second mounting base 2, a first pressing part 3, a second pressing part 4, a force sensor 7, and a displacement sensor 8. At least one of the first mounting base 1 and the second mounting base 2 is movably disposed to move closer to or further away from each other. The first pressing part 3 is disposed on the first mounting base 1, and the second pressing part 4 is disposed on the second mounting base 2. The first pressing part 3 and the second pressing part 4 can be selectively moved closer to or further away from the first mounting base 1 and the second mounting base 2. A first mounting portion is disposed on the side of the first pressing part 3 facing the second pressing part 4, and the first mounting portion is adapted to be mounted on... The circuit board is mounted on the second pressing part 4, which is provided with a second mounting part on the side facing the first pressing part 3. The second mounting part is adapted to mount a mounting shell. The first pressing part 3 is close to the second pressing part 4 to mount the circuit board to the mounting shell. A force sensor 7 is disposed between the first mounting base 1 and the first pressing part 3, or between the second mounting base 2 and the second pressing part 4, or between the first pressing part 3 and the second pressing part 4, to detect the mating pressure between the first pressing part 3 and the second pressing part 4. A displacement sensor 8 is disposed on at least one of the first pressing part 3 and the second pressing part 4, and the displacement sensor 8 is used to detect the movement stroke when the first pressing part 3 and the second pressing part 4 are mated.

[0033] It is understood that at least one of the first mounting base 1 and the second mounting base 2 is movable. The first pressing part 3 and the second pressing part 4 can be selectively moved closer or further away from the first mounting base 1 and the second mounting base 2. When installing the circuit board and the mounting shell, the circuit board is placed on the first mounting part of the first pressing part 3 and the mounting shell is placed on the second mounting part of the second pressing part 4. Then, by moving the first mounting base 1 or the second mounting base 2, the first pressing part 3 is brought closer to the second pressing part 4, thereby pressing and installing the circuit board into the mounting shell.

[0034] In this process, the force sensor 7 can be placed between the first mounting base 1 and the first pressing part 3, or between the second mounting base 2 and the second pressing part 4, or between the first pressing part 3 and the second pressing part 4. It can detect the mating pressure between the first pressing part 3 and the second pressing part 4. Since the precision and pressure tolerance threshold of different circuit boards vary greatly, relying solely on the fixed pressure parameters during automated installation using mechanical settings can easily damage the electronic components on the circuit board due to excessive pressure. However, the force sensor 7 can dynamically feed back pressure information and adjust the approach speed and force of the first pressing part 3 and the second pressing part 4 in a timely manner based on the detected pressure data. This ensures that the installation is completed within the safe pressure range that the circuit board can withstand, and that the pressure is always within the safe range that the circuit board can withstand. This avoids physical damage to the circuit board due to improper pressure and provides a basic guarantee for improving installation quality.

[0035] During installation, the force sensor 7 can continuously monitor pressure changes. When the pressure rises or falls abnormally and exceeds the normal range, it can issue an early warning signal. This may indicate that there are problems such as structural interference on the circuit board or mounting housing, or incorrect component installation positions. Operators can quickly stop the machine for inspection to prevent the problem from worsening and reduce the decline in installation quality caused by potential problems.

[0036] Simultaneously, the testing fixture 100 also includes a displacement sensor 8. The displacement sensor 8 is installed on at least one of the first pressing part 3 and the second pressing part 4, and is used to detect the movement stroke when the first pressing part 3 and the second pressing part 4 are engaged. When installing circuit boards of different models and specifications with mounting shells, the required pressing stroke varies. The displacement sensor 8 can measure the stroke to ensure accurate connection between the circuit board and the mounting shell, and avoid problems such as loose installation and poor contact caused by inadequate pressing. The data of the displacement sensor 8 is closely related to the feedback data of the force sensor 7. When the force sensor 7 detects abnormal pressure changes, it combines the stroke data of the displacement sensor 8 for comprehensive analysis. When the pressure rises abnormally and the movement stroke does not reach the expected level, there may be structural interference; if the pressure drops abnormally and the stroke exceeds the normal range, there may be a deviation in the size of the circuit board or the mounting shell. Through the correlation analysis of force and displacement, problems in the installation process can be judged more comprehensively and accurately, and the installation quality can be further improved.

[0037] Force sensor 7 and displacement sensor 8 detect the mating pressure and movement stroke of the first pressing part 3 and the second pressing part 4, respectively. Force sensor 7 and displacement sensor 8 provide real-time feedback of pressure and stroke data during circuit board installation. Dynamic adjustments can be made based on the data. When force sensor 7 shows that the pressure is close to the critical value, the stroke data of displacement sensor 8 can be used as a reference to determine whether to continue pressing or adjust the pressing speed. This makes the installation process more controllable and avoids problems such as excessive pressure damaging electronic components on the circuit board or insufficient pressure causing a loose connection between the circuit board and the housing. This effectively improves the stability of installation quality.

[0038] Furthermore, by accumulating and analyzing data from force sensor 7 and displacement sensor 8 over a long period, pressure stroke charts for different circuit board and mounting housing combinations can be established. During actual installation, real-time data can be compared with standard curves. When data deviates, potential problems can be predicted in advance and intervention can be carried out to avoid discovering problems in the later stages of installation, thus preventing losses and quality risks.

[0039] According to some embodiments of this application, a testing fixture 100 for circuit board mounting has a first mounting base 1 having a mounting space 11 for accommodating a force sensor 7. The force sensor 7 has a first detection surface 71 and a second detection surface 72 on both sides in the pressing direction. The force sensor 7 is housed in the mounting space 11, and the first detection surface 71 is connected to the inner wall of the mounting space 11, while the second detection surface 72 is connected to the first pressing part 3.

[0040] The first mounting base 1 has an internal mounting space 11 for accommodating the force sensor 7. This space protects the force sensor 7 from external interference, isolates it from the outside world, and effectively blocks external vibrations and electromagnetic fields. This provides a relatively stable working environment for the force sensor 7, enabling it to collect data stably. The acquired pressure data accurately and reliably reflects the mating pressure between the first pressing part 3 and the second pressing part 4, laying the foundation for subsequent circuit board installation based on accurate data.

[0041] Since the first detection surface 71 is connected to the inner wall of the installation space 11, and the inner wall of the installation space 11 is a relatively fixed structure, it provides a stable reference standard for the force sensor 7. This allows the force sensor 7 to distinguish and accurately sense the pressure changes caused by the pressing of the first pressing part 3 and the second pressing part 4 based on the first detection surface 71 connected to the inner wall. This avoids measurement errors caused by the instability of the mounting base itself, ensures the accuracy of the pressure measurement data, and enables subsequent operators to carry out corresponding installation operations and adjustments based on accurate pressure data.

[0042] The second detection surface 72 is connected to the first pressing part 3, forming a pressure transmission path. When the first pressing part 3 is pressed, the pressure generated can be transmitted to the force sensor 7 through the second detection surface 72. The force sensor 7 can capture the pressure change and promptly feed back accurate pressure data. Based on the acquired pressure data, the installation parameters such as the speed at which the first pressing part 3 and the second pressing part 4 approach each other and the force of the pressure applied can be adjusted to ensure that the pressure applied to the circuit board during the entire installation process is always within the safe range that the circuit board can withstand, thus maximizing the protection of the electronic components on the circuit board and effectively improving the installation quality of the circuit board.

[0043] It should be noted that, in the context of the testing fixture 100 used for circuit board mounting, the pressing direction refers to the direction along which the first pressing part 3 moves toward the second pressing part 4 to press the circuit board placed on the first mounting part of the first pressing part 3 into the mounting shell located on the second mounting part of the second pressing part 4.

[0044] According to some embodiments of this application, a test fixture 100 for circuit board mounting has a slider mounting groove 12 formed at the bottom of a first mounting base 1. The slider mounting groove 12 communicates with the mounting space 11, and a slider 32 that cooperates with the slider mounting groove 12 is provided on the first pressing part 3.

[0045] The combination of slider mounting slot 12 and slider 32 enables the disassembly of the first pressing part 3 and the first mounting base 1. In actual production scenarios, circuit boards come in a wide variety of models, with different sizes, shapes, thicknesses, and required installation precision. As production tasks change, when installing new circuit boards of different models, the original first pressing part 3 may not meet its specific installation requirements. In this case, due to the detachable design, the unsuitable first pressing part 3 can be quickly removed from the first mounting base 1, saving time and labor costs for subsequent operations. This avoids the extra effort required for debugging when adapting different circuit boards due to integrated design and non-removable tooling; only the corresponding first pressing part 3 needs to be replaced. The detachable design significantly shortens production line changeover time and improves overall production efficiency.

[0046] The testing fixture 100 for circuit board mounting according to some embodiments of this application further includes a locking member 9, which is movably disposed on the first mounting base 1 to selectively restrict the movement of the slider 32.

[0047] When the current first pressing part 3 needs to be removed, simply move the locking member 9 to release the restriction on the slider 32. The slider 32 can then slide freely within the slider mounting groove 12. The operator can quickly remove the old first pressing part 3 along with the slider 32 from the mounting groove. When installing the new first pressing part 3, align its slider 32 with the slider mounting groove 12 and slide it in. Once the new pressing part reaches the predetermined ideal position, which is usually set in advance based on the size of the new circuit board and the pressing requirements, operate the locking member 9 to restrict the movement of the slider 32. The first pressing part 3 is then fixed and put into use, realizing the rapid replacement of the first pressing part 3, greatly shortening the production changeover time and improving the overall capacity of the production line.

[0048] According to some embodiments of this application, a testing fixture 100 for circuit board mounting has a locking member 9 rotatably disposed on a first mounting base 1 and optionally rotated to face the open direction of the slider mounting groove 12.

[0049] When it is necessary to fix the position of the first pressing part 3, the locking member 9 is rotated to face the open direction of the slider mounting groove 12, which can restrict the movement of the slider 32 in that direction. This avoids the need to spend extra time aligning the snap-fit ​​or plug-in structure. Simply rotating the locking member 9 can quickly restrict or release the slider 32. In production scenarios where different circuit boards are frequently replaced, the position of the first pressing part 3 often needs to be adjusted after each circuit board replacement. After determining the appropriate position, the locking member 9 is rotated to lock it, saving operation time. Moreover, since it is rotatable, the appropriate rotation direction can be selected for locking according to actual usage habits and on-site space conditions, which provides high operational flexibility and further improves production efficiency.

[0050] In some embodiments of this application, the locking member 9 includes a rod and a nut. One end of the rod is rotatably connected to the first mounting base 1, and the other end of the rod is connected to the nut. At least a portion of the rod can be selectively rotated to face the open direction of the slider mounting groove 12. The nut rotates with the rod to face the open direction of the slider mounting groove 12. The slider 32 is provided with a screw hole corresponding to the nut. When the nut rotates with the rod to face the open direction of the slider mounting groove 12, the nut can be engaged with the screw hole to lock the first mounting base 1 and the first pressing part 3.

[0051] According to some embodiments of this application, a testing fixture 100 for circuit board mounting has a second mounting base 2 and a second pressing part 4 detachably connected. A locking member 9 is provided on the second mounting base 2, and the locking member 9 is movably disposed on the second mounting base 2 to selectively restrict the movement of the second pressing part 4.

[0052] In some embodiments of this application, the second mounting base 2 and the second pressing part 4 are detachably connected, which allows for convenient replacement of the appropriate second pressing part 4 when dealing with different circuit boards. This adjusts the mounting shells that are compatible with different circuit boards, enhancing the overall adaptability of the testing fixture 100 to different circuit boards and ensuring that each circuit board can be installed under suitable pressing conditions, thereby guaranteeing installation quality. The movable locking part 9 provided on the second mounting base 2 can selectively restrict the movement of the second pressing part 4 without requiring complex disassembly of the entire fixture, reducing maintenance costs and difficulties, and enabling quick replacement of the second pressing part 4. This can improve production efficiency. At the same time, the locking part 9 itself has a relatively simple structure, and if a fault occurs during long-term use, it is easy to repair or replace.

[0053] According to some embodiments of this application, a testing fixture 100 for circuit board mounting includes a displacement sensor 8 comprising a first detection part and a second detection part. The first detection part is disposed on a first pressing part 3 and moves with the first pressing part 3, and the second detection part is disposed on a second pressing part 4 and moves with the second pressing part 4. One of the first detection part and the second detection part is configured as a stroke pressure column 81, and the other of the first detection part and the second detection part has a detection hole 82 formed on it, which is adapted to cooperate with the stroke pressure column 81 in the pressing direction. A detection element 821 adapted to contact the stroke pressure column 81 is disposed in the detection hole 82.

[0054] It is understandable that the first detection unit moves with the first pressing unit 3, and the second detection unit moves with the second pressing unit 4. When the first pressing unit 3 and the second pressing unit 4 are relatively displaced during the pressing process, the relative position between the stroke pressure column 81 and the detection element 821 in the detection hole 82 will change. By detecting the change in relative position, the displacement between the first pressing unit 3 and the second pressing unit 4 can be indirectly measured, thereby obtaining key information such as the pressing depth and pressing position of the circuit board during the installation process. The contact between the detection element 821 and the stroke pressure column 81 can ensure that the relative displacement between the detection element 821 and the stroke pressure column 81 is detected during the pressing process. When the stroke pressure column 81 enters the detection hole 82 and contacts the detection element 821, as the pressing proceeds, the stroke pressure column 81 will apply pressure to the detection element 821 and generate displacement. The detection element 821 will convert this physical change into an electrical signal or other measurable signal, thereby realizing the accurate measurement of displacement.

[0055] Since the engagement of the stroke pressure column 81 and the detection hole 82 is performed in the pressing direction, interference from other directions can be effectively reduced, making the measurement results more accurately reflect the displacement changes during the pressing process. At the same time, the direct contact between the detection component 821 and the stroke pressure column 81 can achieve high measurement accuracy, which can meet the requirements of high circuit board installation accuracy. During the entire pressing process of circuit board installation, the displacement sensor 8 can monitor the displacement changes between the first pressing part 3 and the second pressing part 4 in real time. The operator can adjust the pressing parameters, such as pressing speed and pressing force, in a timely manner according to the real-time measurement data, thereby ensuring the installation quality of the circuit board and avoiding problems such as circuit board damage or poor connection caused by over- or under-pressing.

[0056] According to some embodiments of this application, the testing fixture 100 for circuit board mounting further includes a first guide portion and a second guide portion. The first guide portion is disposed on the first pressing portion 3 and moves with the first pressing portion 3, and the second guide portion is disposed on the first pressing portion 3 and moves with the second pressing portion 4. One of the first guide portion and the second guide portion is a positioning post 5, and the other of the first guide portion and the second guide portion is a positioning groove 6 that cooperates with the positioning post 5 in the pressing direction. The positioning groove 6 is used to limit the movement trajectory of the positioning post 5.

[0057] During circuit board assembly, the first pressing part 3 and the second pressing part 4 need to move precisely relative to each other to ensure accurate pressing of the circuit board and the mounting shell. The cooperation between the positioning post 5 and the positioning groove 6 provides guidance for the first pressing part 3 and the second pressing part 4, ensuring that the first pressing part 3 and the second pressing part 4 maintain an accurate relative position in the pressing direction. This guarantees the installation accuracy of the circuit board and avoids damage to the circuit board due to pressing position deviation. During the pressing process, factors such as mechanical vibration and friction between components may cause the first pressing part 3 and the second pressing part 4 to shift. The limiting effect of the positioning post 5 in the positioning groove 6 can effectively restrict this shift, ensuring that the pressing part can only move along a predetermined trajectory. This improves the stability and repeatability of the pressing process, ensuring that the accuracy of each pressing meets the requirements. In mass production of circuit boards, rapid and accurate positioning is crucial for improving production efficiency. The cooperation between the positioning post 5 and the positioning groove 6 allows the first pressing part 3 and the second pressing part 4 to quickly and accurately reach the predetermined position before each pressing, reducing adjustment and alignment time and thus improving production efficiency.

[0058] According to some embodiments of this application, a testing fixture 100 for circuit board mounting is provided, wherein the second testing unit is configured such that when the positioning post 5 engages with the positioning groove 6, the travel pressure post 81 engages with the testing hole 82.

[0059] Understandably, when the first pressing part 3 and the second pressing part 4 achieve positioning and engagement, the displacement sensor 8 also simultaneously begins displacement measurement. The cooperation between the positioning post 5 and the positioning groove 6 ensures the accuracy of the two pressing parts in the pressing direction and relative position. At the same time, the cooperation between the stroke pressing post 81 and the detection hole 82 can capture the displacement changes during the pressing process. Through coordinated cooperation, both the initial precise alignment can be guaranteed, and the displacement generated by subsequent pressing can be monitored in real time, thereby comprehensively ensuring the displacement accuracy requirements during circuit board installation. When performing circuit board installation operations, it is only necessary to focus on the positioning post 5 and the positioning groove 6. The operation of positioning slot 6 is sufficient, because once the positioning post 5 accurately enters the positioning slot 6, it means that the entire tooling structure is in the correct initial installation state. At this time, the stroke pressure post 81 and the detection hole 82 also automatically cooperate, and the displacement sensor 8 starts to work normally. This avoids the need to adjust the positioning structure and the displacement sensor 8 separately to check if they are ready, simplifies the operation process, and saves operation time. On a large-scale circuit board production line, each installation operation can complete the preparation work more quickly, thereby improving the overall production efficiency and reducing the time wasted and potential human error caused by cumbersome operations.

[0060] According to some embodiments of this application, a testing fixture 100 for mounting a circuit board has a first mounting part configured as an adsorption claw 31 to be adsorbed and connected to the circuit board, and a second mounting part configured as a mating groove 41 to restrict the displacement of the mounting shell.

[0061] The suction claws 31 can form an adsorption connection with the circuit board by generating suction force, avoiding damage to the surface of the circuit board. Existing mechanical clamps will squeeze and scrape the surface of the circuit board. The suction claws 31 can adsorb the circuit board. At the same time, multiple suction claws 31 can be arranged at intervals to apply adsorption force to the circuit board from multiple directions, which can better fix the circuit board and ensure that the position of the circuit board will not shift when it is subsequently pressed with the second pressing part 4, thereby improving the installation accuracy and ensuring that the circuit board can accurately dock with the corresponding mounting part. Correspondingly, the second mounting part is constructed as a mating groove 41. When the circuit board is installed, the mounting shell needs to accurately mate with the circuit board. The mating groove 41 can ensure that the mounting shell does not undergo unnecessary translation, rotation or other displacement during the pressing process. The mating groove 41 can hold at least a part of the mounting shell, fixing the mounting shell in the predetermined position, ensuring accurate docking with the circuit board, and preventing installation failure or poor contact problems caused by the position deviation of the mounting shell.
