[0029] See also Figure 1As shown, the utility model provides a test system for the relationship between the board installation angle and the pressure ratio, including: a tool pressing mechanism 1, a force value display controller 2, a first angle value display controller 3, a second angle value display controller 4 and an MES all-in-one machine 5, the tool pressing mechanism 1 is respectively connected to the force value display controller 2, the first angle value display controller 3 and the second angle value display controller 4, and the MES all-in-one machine 5 is respectively connected to the force value display controller 2, the first angle value display controller 3 and the second angle value display controller 4.

[0035] Specifically, the tool pressing mechanism 1, as a force-applying component during the installation of the board 6 to be tested, realizes the data collection of the pressing force and the tilt angles in the X and Y directions. The tool pressing mechanism 1 is fixedly mounted with a first pressure sensor 101, a second pressure sensor 102, an X-axis angle measuring instrument 103, and a Y-axis angle measuring instrument 104 to realize the collection of the above data.

[0036] Among them, the output ends of the first pressure sensor 101 and the second pressure sensor 102 are respectively connected to the input end of the force value display controller 2 through a signal cable, and the output end of the force value display controller 2 is connected to the MES integrated machine 5 through a serial port. When there is a pressure value output, the force value control display instrument 2 displays the combined force of the first pressure sensor and the second pressure sensor in real time, and uploads the combined force value in real time and records it in the preset data table of the MES integrated machine 5. The output end of the X-axis angle measuring instrument 103 is connected to the input end of the first angle value display controller 3 through a signal cable, and the output end of the Y-axis angle measuring instrument 104 is connected to the input end of the second angle value display controller 4 through a signal cable. The output end of the first angle value display controller 3 and the output end of the second angle value display controller 4 are respectively connected to the MES integrated machine 5 through a serial port; when the board to be tested is installed in place, the first angle value display controller 3 and the second angle value display controller 4 upload the tilt angle values ​​of the board to be tested 6X and Y directions in real time and record them in the preset data table of the MES integrated machine 5.

[0037] Among them, the X-axis angle measuring instrument 103, the first pressure sensor 101, the Y-axis angle measuring instrument 104, and the second pressure sensor 102 are all standard parts.

[0038] This embodiment provides a test system for the relationship between board installation angle and pressure ratio, which can detect the pressing force and tilt angle data when installing the board in real time, determine the corresponding relationship between the pressure value and the angle, thereby standardizing the operator's working range and ensuring the installation yield.

[0039] As an example, the present invention also discloses a test system for the relationship between the board installation angle and the pressure ratio. The system architecture of this embodiment is as follows:

[0040] The system includes: a tool pressing mechanism 1, a force value display controller 2, a first angle value display controller 3, a second angle value display controller 4 and an MES integrated machine 5. Among them, the tool pressing mechanism 1 is provided with a first pressure sensor 101, a second pressure sensor 102, an X-axis angle measuring instrument 103 and a Y-axis angle measuring instrument 104. The first pressure sensor 101 and the second pressure sensor 102 are used to collect the pressing force received during the installation of the board 6 to be tested, and the X-axis angle measuring instrument 103 and the Y-axis angle measuring instrument 104 are used to collect the tilt angle values ​​in the X direction and the Y direction during the installation of the board 6 to be tested. Among them, the force value display controller 2 is respectively connected to the MES integrated machine 5, the first pressure sensor 101 and the second pressure sensor 102 for data, the first angle value display controller 3 is respectively connected to the MES integrated machine 5 and the X-axis angle measuring instrument 103 for data, and the second angle value display controller 4 is respectively connected to the MES integrated machine 5 and the Y-axis angle measuring instrument 104 for data.

[0041] In this embodiment, the data collection of the pressing force and the tilt angles in the X and Y directions during the installation of the board 6 to be tested is achieved through the inventive structure of the tool pressing mechanism 1 .

[0042] like Figure 2 As shown, the tool pressing mechanism 1 includes an L-shaped pressing plate 105 and a handle 106. A board mounting assembly is provided at the bottom of the L-shaped pressing plate 105, and the board 6 to be tested is fixedly installed at the bottom of the L-shaped pressing plate 105 through the board mounting assembly. The first pressure sensor 101 and the second pressure sensor 102 are fixedly installed on the top of the L-shaped pressing plate 105, corresponding to the two sides of the board 6 to be tested. The bottoms of the first end and the second end of the handle 106 are respectively fixedly installed with connecting fixtures 107. The first end of the handle 106 is fixedly installed on the first pressure sensor 101 through the connecting fixture 107, and the second end of the handle 106 is fixedly installed on the second pressure sensor 102 through the connecting fixture 107. By using the connecting fixture to connect the pressure sensor and the handle respectively, the handle can be used to conveniently apply pressure to the board during installation. Compared with installing only one pressure sensor in the middle of the force application part, it is more conducive to accurately measuring the pressure value applied during installation. The X-axis angle measuring instrument 103 and the Y-axis angle measuring instrument 104 are respectively fixedly mounted on the top of the L-shaped pressing plate 105 through the angle measuring instrument fixing block 112. Both the X-axis angle measuring instrument 103 and the Y-axis angle measuring instrument 104 are digital displays, and the numbers can be accurately displayed on the display screen when tilted. When the board to be tested is installed, the installation tilt angle can be determined from the X and Y directions respectively.

[0043] Specifically, Figure 3 The L-shaped pressing plate 105 shown includes a vertically connected transverse pressing plate 108 and a longitudinal pressing plate 109, the first pressure sensor 101 and the second pressure sensor 102 are fixedly installed on the top of the transverse pressing plate 108 along the X-axis direction, the X-axis angle measuring instrument 103 is fixedly installed on the top of the transverse pressing plate 108, and the Y-axis angle measuring instrument 104 is fixedly installed on the top of the longitudinal pressing plate 109.

[0044] The board installation assembly includes a limiting groove 110 and a board bracket 111. The limiting groove 110 is fixedly installed along the X-axis direction at the bottom of the horizontal pressure plate 108. The board bracket 111 is arranged at both ends of the limiting groove 110, and the top of the board bracket is fixedly connected to the bottom of the horizontal pressure plate. The limiting groove 110 and the board bracket 111 form a fixed structure adapted to the board 6 to be tested. A 0.5mm spacing is reserved between the single side of the limiting groove 110 and the board bracket 111, ensuring that the L-shaped pressing plate 105 can smoothly and accurately clamp the board 6 to be tested, and ensuring the consistency between the tool pressing mechanism 1 and the board 6 to be tested during pressing. When in use, the left and right ends of the board 6 to be tested are attached to the board bracket 111 by screws, and the top of the board 6 to be tested is clamped in the limiting groove 110.

[0045] It should be noted that the board bracket 1 can adopt a frame-shaped structure adapted to the board to be tested to fix the board to be tested, wherein the top, left and right ends of the board to be tested can be fixed by using the positioning holes of the board itself. The bottom end of the board to be tested can be fixed without affecting the gold finger insertion.

[0046] It can be seen that the use of the tool pressing mechanism 1 can achieve the following technical effects during the assembly process of the board:

[0047] 1. When manually installing the board, record the operator's habitual installation tilt angle;

[0048] 2. When manually installing the board, record the pressure value corresponding to the different installation inclination angles;

[0049] 3. Record the tilt angle and pressure value during installation. The gold finger of the board will damage the motherboard slot.

[0050] 4. By measuring the inclination angle and pressure value, the operator's working movements can be regulated within the range, ensuring the installation yield and avoiding the occurrence of damaged parts.

[0051] In addition, it should be specially noted that the X-axis angle measuring instrument 103, the first pressure sensor 101, the Y-axis angle measuring instrument 104, and the second pressure sensor 102 are all standard parts; the angle measuring instrument fixing block 112, the connecting fixing 107, and the handle 106 are made of aluminum AL6061, which ensures strength and light weight; the L-shaped pressing plate 105 is made of anti-static Bakelite, which ensures the conditions for static electricity requirements and prevents static electricity from breaking through the board.

[0052] The present embodiment provides a test system for the relationship between the board installation angle and the pressure ratio. By using a tool pressing mechanism, a force value display controller, a first angle value display controller, a second angle value display controller and an MES all-in-one machine 5, it is possible to record the operator's habitual installation tilt angle and the pressure values ​​corresponding to different installation tilt angles in real time when the board is manually installed. When the board gold finger causes damage to the motherboard slot, the ratio of the corresponding tilt angle value to the pressing force value can be determined, and the maximum value of the ratio of the tilt angle to the pressing force allowed during installation can be determined. By measuring the tilt angle and the pressing force value in real time, the operator's operating actions can be standardized, the installation yield rate can be guaranteed, and the occurrence of damaged parts can be avoided.

[0053] When in use, the utility model realizes the test of the relationship between the board installation angle and the pressure ratio through the following steps.

[0054] Step 1: Clamp the top of the board to be tested into the limiting groove and fasten it to the board bracket with screws so that the board to be tested is fixed at the bottom of the tooling pressing mechanism.

[0055] Through this step, the board to be tested is fixed at the bottom of the tool pressing mechanism, so that the tool pressing mechanism is used to collect data on the pressing force and the tilt angles in the X and Y directions during the installation of the board to be tested.

[0056] During fixed installation, it is necessary to ensure that the L-shaped pressing plate can smoothly and accurately clamp the board to be tested, and ensure the consistency between the tooling pressing mechanism and the board to be tested during pressing.

[0057] Step 2: Use the handle to apply downward force to insert the gold finger of the board to be tested into the DIMM slot of the motherboard.

[0058] Step 3: During insertion, the first angle value display controller and the second angle value display controller respectively display the tilt angle values ​​in the X and Y directions; the force value control display displays the resultant force of the first pressure sensor and the second pressure sensor in real time, and uses the resultant force value as the pressing force value at the corresponding tilt angle during operation.

[0059] Step 4: Upload the tilt angle value and pressing force value to the MES integrated machine in real time and save them in the preset data table.

[0060] Among them, the MES all-in-one machine is pre-installed with data spreadsheet processing tools, such as Excel spreadsheet tools, which can record and count the tilt angle values ​​and pressing force values ​​through pre-edited data spreadsheet documents.

[0061] Step 5: Calculate the ratio of the tilt angle value to the pressing force value, and record the corresponding ratio of the tilt angle value to the pressing force value after a damaged part appears during the installation process as the extreme value of the ratio of the tilt angle to the pressing force of the corresponding board to be tested.

[0062] In this step, a preset formula can be used to set up a separate column in the data table to count the ratios, and the extreme values ​​of the ratios can be specially marked. After all the tests are completed, the data table can be used as a reference to formulate the operator's work specifications.

[0063] In summary, the utility model can detect the pressing force and tilt angle data when installing the board in real time, determine the corresponding relationship between the pressure value and the angle, thereby standardizing the operator's operating range and ensuring the installation yield.

The same or similar parts between the embodiments can be referred to each other. As for the method disclosed in the embodiment, since it corresponds to the system disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
