Description

Technical Field

[0001] This utility model relates to a docking test fixture, specifically a self-calibration docking test fixture for an embedded industrial control computer board. Background Technology

[0002] Embedded industrial control computer boards are dedicated computer cores tailored for harsh industrial environments. With their high reliability, rich interfaces, compact structure, and long lifespan, they have become an indispensable key component in modern intelligent manufacturing and automated equipment. Unlike home computers that pursue extremely high performance and stylish appearance, they aim to complete specific industrial control tasks under the most stable, robust, and dedicated conditions. Due to the special nature of their operating environment, their stability needs to be tested to ensure they meet the usage requirements.

[0003] Common testing equipment includes a control console, on which wiring modules and board mounting bases are fixedly installed. In use, the board is placed on the mounting base and its position is adjusted to ensure that the board and wiring modules can be accurately connected. The control console is equipped with a testing module, which tests the board and provides feedback on the test results.

[0004] Traditional industrial control board testing involves placing the board, tightening screws, and carefully aligning and inserting it into the backplane or wiring module—a time-consuming and tedious process. Furthermore, it's impossible to guarantee that the board's position and angle will be perfectly consistent each time. This inconsistency can lead to fluctuating test results, making it difficult to determine whether the problem lies with the board itself or with poor connection. Utility Model Content

[0005] The purpose of this invention is to provide a self-calibration docking test fixture for embedded industrial control computer boards to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A self-calibration docking test fixture for an embedded industrial control computer board includes a control console; a base is mounted on the control console; and a wiring module is mounted on the base. It also includes a support platform; rollers that roll in cooperation with the base are rotatably mounted on the support platform. The positioning element includes clamping plates symmetrically mounted on the support platform, the clamping plates being able to move closer or further apart from each other to clamp, position, or release the board module; It also includes a docking component, which can move the platform closer to or away from the wiring module and drive the positioning component to move.

[0007] The self-calibration docking test fixture for the embedded industrial control computer board as described above includes: a motor mounted on the base, a lead screw on the output end of the motor, and a threaded sleeve threadedly connected to the lead screw; a docking groove is provided on the base; a connecting block that slides and engages with the docking groove is installed on the support platform; and the threaded sleeve is connected to the connecting block.

[0008] The self-calibration docking test fixture for the embedded industrial control computer board as described above includes: the docking component further includes a slide rod mounted on the threaded sleeve, the slide rod being slidably engaged with the connecting block; and a first spring is wrapped around the slide rod, the two ends of the first spring respectively abutting against the threaded sleeve and the connecting block; a baffle is installed at the end of the slide rod.

[0009] The self-calibration docking test fixture for the embedded industrial control computer board as described above includes: the positioning component further includes an extrusion plate; a guide rod that slides and engages with the extrusion plate is mounted on the clamping plate; a second spring is wrapped around the guide rod; the two ends of the second spring respectively abut against the extrusion plate and the clamping plate; a positioning groove is provided on the support platform; a slider that slides and engages with the positioning groove is mounted on the extrusion plate.

[0010] The self-calibration docking test fixture for the embedded industrial control computer board as described above includes a clamping inclined groove and a clamping straight groove formed on the base; one end of the clamping inclined groove is connected to one end of the clamping straight groove; and a sliding column is installed on the slider, which is slidably engaged with both the clamping inclined groove and the clamping straight groove.

[0011] The self-calibration docking test fixture for the embedded industrial control computer board as described above: the clamping slant is inclined, and the distance between it and the docking straight groove increases as the distance between it and the wiring module increases.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The circuit board is automatically clamped by two symmetrical clamping plates, aligning its centerline with the centerline of the support platform.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1-4 As an embodiment of this utility model, the self-calibration docking test fixture for the embedded industrial control computer board includes a control console 1; a base 2 is mounted on the control console 1; and a wiring module 201 is mounted on the base 2. It also includes a support platform 6; a roller 602 that rolls with the base 2 is rotatably mounted on the support platform 6. The positioning component includes clamping plates 11 symmetrically mounted on the support 6. The clamping plates 11 can move closer to or further away from each other to clamp, position, or release the board module. It also includes a docking component, which can move the platform 6 closer to or further away from the wiring module 201 and drive the positioning component to move.

[0020] In this embodiment, the embedded industrial control computer board is placed flat on the support platform 6, and the device is started, thereby driving the docking parts and positioning parts to move.

[0021] When the docking component moves, it will cause the base 6 to gradually approach the wiring module 201 (the roller 602 will roll on the base 2), thereby causing the industrial control computer board to approach the wiring module 201; at the same time as the docking component moves, the positioning component will also move, causing the two symmetrical clamping plates 11 to move closer to each other to clamp the industrial control computer board; thereby causing the center line of the industrial control computer board to coincide with the center line of the base 6, and enabling the board to be fixed on the base 6.

[0022] Afterwards, the docking component continues to operate, thereby driving the board and the wiring module 201 to come into contact through the support platform 6, so that the wiring module 201 docks with the board. During this process, the positioning component always maintains the clamping state of the board to reduce the difficulty of docking.

[0023] Next, the board is tested through the system in console 1, and the test results are reported.

[0024] Two symmetrical clamping plates 11 automatically clamp the board, aligning its centerline with the centerline of the support platform 6. This process eliminates any possible misalignment during placement, ensuring that the board is always fixed in a unique and precise position. Because the board is precisely fixed and the positioning elements remain clamped throughout the docking process, the connectors on the board and the interface of the wiring module 201 can be aligned very accurately, greatly improving the success rate and reliability of docking and preventing connector damage due to misalignment.

[0025] As a further embodiment of this utility model, the docking component includes a motor 3 mounted on the base 2, a lead screw 4 mounted on the output end of the motor 3, and a threaded sleeve 5 threadedly connected to the lead screw 4; a docking groove 202 is provided on the base 2; a connecting block 7 is mounted on the support 6 and slidably engages with the docking groove 202; and the threaded sleeve 5 is connected to the connecting block 7.

[0026] As a further embodiment of this utility model, the mating component further includes a slide rod 8 mounted on the threaded sleeve 5, the slide rod 8 being slidably engaged with the connecting block 7; and a first spring 9 is wrapped around the slide rod 8, the two ends of the first spring 9 respectively abutting against the threaded sleeve 5 and the connecting block 7; a baffle 801 is installed at the end of the slide rod 8.

[0027] In this embodiment, after the board is placed on the support 6, the motor 3 is started, thereby driving the lead screw 4 to rotate, and through the threaded engagement with the threaded sleeve 5, the threaded sleeve 5 moves closer to the wiring module 201 along the length direction of the lead screw 4.

[0028] In the initial position, the first spring 9 has a compression amount. Therefore, during the movement of the threaded sleeve 5, the connecting block 7 will move synchronously through the first spring 9, thereby driving the bearing platform 6 to move synchronously, so as to drive the board to approach the wiring module 201.

[0029] When the board comes into contact with the wiring module 201, the resistance to the movement of the connecting block 7 increases. At this time, the moving threaded sleeve 5 will drive the slide bar 8 to slide on the connecting block 7 and compress the first spring 9. On the one hand, the elastic force of the first spring 9 assists in the docking of the board and the wiring module 201, which can improve the stability of the connection between the two, thereby avoiding large errors in the test results due to poor contact during the test. On the other hand, the elastic force of the first spring 9 can avoid rigid contact between the board and the wiring module 201, thereby avoiding damage to the wiring module 201 or the board due to excessive pressure.

[0030] After the test is completed, the motor 3 drives the lead screw 4 to rotate in the opposite direction, thereby moving the threaded sleeve 5 away from the wiring module 201. During this process, the slide bar 8 will slide on the connecting block 7 and gradually restore the first spring 9. After the first spring 9 is reset, the baffle 801 will abut against the connecting block 7. The threaded sleeve 5, which continues to move, will drive the connecting block 7 to move synchronously through the baffle 801, thereby driving the support 6 and the plate to reset.

[0031] As a further embodiment of this utility model, the positioning component further includes a pressing plate 10, and a guide rod 1101 that is slidably engaged with the pressing plate 10 is mounted on the clamping plate 11. A second spring 14 is wrapped around the guide rod 1101. The two ends of the second spring 14 respectively abut against the pressing plate 10 and the clamping plate 11. A positioning groove 601 is provided on the support 6. A slider 12 that is slidably engaged with the positioning groove 601 is mounted on the pressing plate 10.

[0032] In this embodiment, as the support platform 6 approaches the wiring module 201, the slider 12 slides closer in the positioning groove 601, thereby driving the extrusion plates 10 to approach each other, so as to drive the clamping plate 11 to approach synchronously and abut against the board.

[0033] During the process of both clamping plates 11 contacting the plate, the center line of the plate gradually coincides with the center line of the support platform 6 under the squeezing action of the clamping plates 11. This process eliminates any possible offset during placement, ensuring that the plate is fixed in a unique and precise position each time. The slider 12 will then continue to slide closer, causing the extrusion plate 10 to move synchronously. During this process, the guide rod 1101 will slide on the extrusion plate 10, and the second spring 14 will be compressed. The elastic force of the second spring 14 increases the clamping force between the clamping plate 11 and the board, thereby ensuring that the board will not be displaced during the docking of the board and the wiring module 201, and the elastic force of the second spring 14 can prevent the board from being damaged due to excessive pressure.

[0034] As a further embodiment of this utility model, the positioning component also includes a clamping inclined groove 203 and a clamping straight groove 204 formed on the base 2; wherein one end of the clamping inclined groove 203 is connected to one end of the clamping straight groove 204; and a sliding column 13 is installed on the slider 12, which is slidably engaged with both the clamping inclined groove 203 and the clamping straight groove 204.

[0035] As a further embodiment of this utility model, the clamping groove 203 is inclined, and the distance between it and the docking straight groove 202 increases as the distance between it and the wiring module 201 increases.

[0036] In this embodiment, as the support platform 6 approaches the wiring module 201, it will drive the slider 12 to move synchronously, thereby driving the sliding column 13 to approach the wiring module 201.

[0037] During the movement of the sliding column 13, it will slide in the clamping groove 203. Since the clamping groove 203 is inclined, and the distance between it and the docking straight groove 202 increases as the distance between it and the wiring module 201 increases, the sliding column 13 will gradually approach the docking straight groove 202, thereby driving the slider 12 to slide in the positioning straight groove 601, so as to drive the two clamping plates 11 to move closer to each other to clamp the board.

[0038] Subsequently, the sliding column 13 will slide in the clamping straight groove 204, which is parallel to the straight groove 202. Therefore, the relative position of the sliding column 13 and the straight groove 202 remains unchanged, and the position of the slider 12 remains unchanged, thus maintaining the clamping state of the board. Since the board is precisely fixed and the positioning component always maintains the clamping state during the docking process, the connector on the board and the interface of the wiring module 201 can be aligned very precisely, which greatly improves the success rate and reliability of docking and avoids connector damage caused by misalignment.

[0039] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
