[0035] Embodiment 1

[0036] The embodiment of the utility model provides an FPC module test fixture, which can realize an automated test process of the FPC module and has high operating efficiency.

[0037] See also Figure 1 and Figure 2The FPC module test fixture provided by the embodiment of the utility model includes a support assembly 10, a test assembly 20 and a drive assembly 30. Among them, the support assembly 10 includes a support bottom plate 11 and a support top plate 12, at least one support column 13 is arranged between the support top plate 12 and the support bottom plate 11, one end of the support column 13 is fixedly connected to the support bottom plate 11, and the other end of the support column 13 is fixedly connected to the support top plate 12; a detection port 121 is opened on the support top plate 12, and the part to be detected can be placed at the detection port 121; the test assembly 20 includes a moving plate 21 and a tester 22, the moving plate 21 is arranged between the support top plate 12 and the support bottom plate 11, the moving plate 21 is slidably connected to the support column 13, the tester 22 is arranged on the moving plate 21, and the moving plate 21 can drive the tester 22 to move and pass through the detection port 121 and contact with the part to be detected; the drive assembly 30 is arranged on the support assembly 10, and the drive assembly 30 can drive the moving plate 21 to move along the axial direction of the support column 13.

[0038] The support assembly 10 ensures that the test fixture has high stability and structural strength. The support column 13 connects the support bottom plate 11 and the support top plate 12 to form a solid frame, so that the tester 22 can be accurately moved above the part to be tested during the test. In particular, the detection port 121 on the support top plate 12 provides an accurate positioning point for the part to be tested, and can also guide the part to be tested, ensuring the correct docking of the tester 22 with the part to be tested. When in use, the driving assembly 30 drives the moving plate 21 to move up along the support column 13 until the moving plate 21 fits with the support top plate 12, and the tester 22 passes through the detection port 121 and contacts the part to be tested, thereby completing the detection process of the part to be tested. After the detection is completed, the part to be tested is taken out, and the driving assembly 30 drives the moving plate 21 to move down to perform the next test. Through the coordinated cooperation of the driving assembly 30 and the test assembly 20, the automated testing process of the part to be tested is realized, the complex and cumbersome manual operation process is avoided, and the operating efficiency is improved. The moving process of the moving plate 21 can be precisely controlled by the driving assembly 30, thereby improving the control accuracy of the components. Generally speaking, the support bottom plate 11 and the support top plate 12 are placed horizontally and arranged in parallel, the support top plate 12 is directly opposite to the top surface of the support bottom plate 11, and the support column 13 extends in the vertical direction. For the convenience of description in conjunction with the drawings, the directions below are described in the directions shown in the drawings, but are not limited thereto.

[0039] Regarding the support assembly 10, in this embodiment, the support top plate 12 and the support bottom plate 11 have the same area and are both rectangular, which is convenient for processing, transportation and installation operations. There are four support columns 13, which are distributed at the four corners of the rectangle, so that they have a high bearing capacity and can evenly distribute the load on the support top plate 12, so that they have high stability. In other embodiments, the support columns 13 can also be provided with six, eight, etc., which are not limited here. In other embodiments, the support column 13 includes an adjustment component, which can adjust the length of the support column 13 to adapt to different working conditions and improve the adaptability of the support column 13. On the support top plate 12, a plurality of detection ports 121 are provided, and the plurality of detection ports 121 are arranged at intervals along the width direction of the support top plate 12, so that multiple parts to be detected can be tested at one time, which improves the operating efficiency. The size, number, and arrangement direction of the detection ports 121 can be adaptively selected according to actual conditions, which are not limited here.

[0040] The test assembly 20 is used to implement the test process of the part to be tested. Specifically, in the present embodiment, the movable plate 21 is rectangular, and four through holes are provided at the four corners of the movable plate 21 at positions directly opposite to the support column 13. The support column 13 passes through the through holes and is slidably connected with the movable plate 21, thereby improving the stability and smoothness of the movable plate 21 when moving along the support column 13, reducing the swing and vibration of the movable plate 21 during the movement, and improving the accuracy of the contact between the tester 22 and the part to be tested. In addition, the support column 13 can also provide a guiding effect for the movement process of the movable plate 21, thereby ensuring the stability of the movable plate 21 during the movement process. In other embodiments, a guide slider can also be provided on the movable plate 21, and a guide rail can be provided on the support column 13. The sliding connection between the movable plate 21 and the support column 13 is realized through the cooperation of the guide slider and the guide rail, which will not be elaborated here.

[0041] A matching tester 22 is provided for each detection port 121 on the movable plate 21. The size of the tester 22 is slightly smaller than the size of the detection port 121, thereby improving the moving efficiency of the tester 22 and preventing the tester 22 from getting stuck with the detection port 121 and affecting the test process. After the tester 22 passes through the detection port 121 and contacts the part to be detected, it can perform the test process on the part to be detected. The specific structure and working principle of the tester 22 are common technical equipment in this field and will not be elaborated here.

[0042] The driving assembly 30 is used to drive the moving plate 21 to move. Specifically, the driving assembly 30 includes a driving member and a transmission rod 33. The driving member is arranged on the supporting top plate 12 or the supporting bottom plate 11. One end of the transmission rod 33 is connected to the driving member, and the other end of the transmission rod 33 is connected to the moving plate 21. The driving member can drive the transmission rod 33 to drive the moving plate 21 to move. Through the driving member and the transmission rod 33, the automatic control of the moving plate 21 is realized, so that the test process is more efficient and standardized, the error of human operation is reduced, and the consistency and repeatability of the test results are ensured; the direct control of the driving member to the transmission rod 33 allows the position and speed of the moving plate 21 to be accurately adjusted, and the control accuracy is improved.

[0043] In this embodiment, the driving member is arranged on the supporting bottom plate 11, and the transmission rod 33 is arranged on the top of the driving member. The driving member drives the transmission rod 33 to move. The driving member is arranged on the supporting bottom plate 11 for easy installation. No additional suspension device is required. The driving member can be directly placed on the supporting bottom plate 11 for easy operation and subsequent maintenance. In other embodiments, the driving member can also be arranged on the supporting top plate 12, as long as it can drive the moving plate 21 to move, and there is no limitation here.

[0044] Specifically, in this embodiment, the driving member includes a cylinder 301, and the transmission rod 33 is a telescopic rod 302. The telescopic rod 302 is connected to the cylinder 301, and the telescopic end of the telescopic rod 302 is connected to the moving plate 21. The cylinder 301 can drive the telescopic rod 302 to extend or contract, thereby driving the moving plate 21 connected thereto to move up or down. The cylinder 301 is convenient for material acquisition, replacement and maintenance, and has a high driving efficiency. The cylinder 301 is a common mechanical device in the art, and its specific structure and working principle are not described here.

[0045] It is worth noting that because the test takes a certain amount of time, when the test is qualified, the movable plate 21 drives the tester 22 to move downward and is directly separated from the workpiece to be tested. After that, the operator can take the qualified workpiece to be tested from the test port 121 of the support top plate 12; when the test is unqualified, the tester 22 is not separated from the workpiece to be tested, and the operator is required to drive the cylinder 301 to separate the tester 22 from the workpiece to be tested, so as to distinguish the quality of the workpiece to be tested and facilitate classification and storage.

[0046] In order to prevent the tester 22 from driving the test piece to be detected to move when the test piece and the tester 22 are separated, thereby causing damage to the test piece, the FPC module test fixture provided in this embodiment also includes a clamping assembly 40, and the clamping assembly 40 includes a moving mechanism 41 and a clamping arm 42. A clamping arm 42 is respectively provided on both sides of each detection port 121, and the moving mechanism 41 can drive the two clamping arms 42 to move closer to or away from each other to clamp or loosen the test piece. The clamping assembly 40 drives the clamping arms 42 to move closer to each other through the moving mechanism 41, so that the test piece can be stably clamped, ensuring that the test piece remains fixed when the test piece is separated from the tester 22 during the test process, which can effectively prevent the unexpected movement of the test piece caused by the movement of the tester 22, thereby reducing the risk of damage and improving safety.

[0047] Regarding the specific structure of the mobile mechanism 41, the mobile mechanism 41 includes a brake part and a rotating rod 410, the brake part is connected to the rotating rod 410, and the rotating rod 410 is threadedly connected to the clamping arm 42. The brake part can drive the rotating rod 410 to rotate around its own axis, thereby driving the clamping arm 42 to move axially along the rotating rod 410. Through the threaded connection between the rotating rod 410 and the clamping arm 42, it is possible to achieve accurate control of the movement of the clamping arm 42, and then finely adjust the clamping force of the clamping arm 42 on the part to be detected, ensuring that the part to be detected is firmly and properly clamped, which not only avoids damage to the part to be detected due to over-tight clamping, but also prevents the part to be detected from moving or slipping due to insufficient clamping. The threaded connection between the rotating rod 410 and the clamping arm 42 ensures the uniform distribution of the clamping force on the part to be detected, reduces the uneven pressure on the surface of the part to be detected, which is particularly important for soft or easily deformed FPC modules, and helps to maintain the integrity and functionality of the part to be detected. Due to the design of the brake part, the operator can easily control the opening, closing and movement of the clamping arm 42 without manual adjustment, making the operation easier and faster, reducing the difficulty of operation and improving work efficiency.

[0048] Specifically, the outer periphery of the rotating rod 410 is provided with a positive thread portion and a negative thread portion along its own axial direction, and the thread rotation directions of the positive thread portion and the negative thread portion are opposite, and the two clamping arms 42 located on both sides of the same detection port 121 are respectively threadedly connected with the positive thread portion and the negative thread portion. By providing the positive thread portion and the negative thread portion on the rotating rod 410, and making the clamping arms 42 on both sides threadedly connected thereto, the two clamping arms 42 can be controlled to move in opposite directions at the same time by driving the rotating rod 410 to rotate once, thereby realizing the synchronous opening and closing of the two clamping arms 42, and improving the operation efficiency and simplicity.

[0049] In other embodiments, the threads of the two clamping arms 42 are rotated in opposite directions, so as to ensure that the two clamping arms 42 can be moved in opposite directions by rotating the rotating rod 410, which is not limited here.

[0050] In this embodiment, the end of the rotating rod 410 is connected to a first brake shaft 411, and the rotating rod 410 can be driven to rotate around its own axis by driving the first brake shaft 411 to rotate. The first brake shaft 411 can be driven manually or connected to a motor for driving, which are common means in the art and will not be described in detail here.

[0051] In order to adapt to the operating habits of different personnel and different working environments, a driven bevel gear 413 is keyed to the first brake shaft 411, and the driven bevel gear is meshed with the driving bevel gear 414. The second brake shaft 412 is fixedly connected to the driving bevel gear 414, and the second brake shaft 412 is arranged perpendicular to the first brake shaft 411, thereby changing the driving direction, and the first brake shaft 411 can be directly driven in the horizontal direction to drive the rotating rod 410 to rotate; the second brake shaft 412 can be driven in the vertical direction to rotate, and the torque is transmitted through the cooperation of the driven bevel gear and the driving bevel gear, thereby indirectly driving the third drive shaft to rotate and driving the rotating rod 410 to rotate, so that different personnel and different machines can be driven from different angles, and it has high adaptability.

[0052] Embodiment 2

[0053] Figure 3 and Figure 4 , shows an embodiment 2, in which the parts identical or corresponding to the embodiment 1 are marked with the corresponding reference numerals of the embodiment 1. For the sake of simplicity, only the differences between the embodiment 2 and the embodiment 1 are described. The difference is that in this embodiment, the transmission rod 33 includes a fixed block 331 and a lifting rod 332, a guide cavity is formed in the fixed block 331, the lifting rod 332 is slidably connected to the guide cavity, and the driving member is connected to the lifting rod 332. The driving member can drive the lifting rod 332 to move along the guide cavity, thereby driving the moving plate 21 to move. The sliding connection between the guide cavity and the lifting rod 332 can make the movement of the lifting rod 332 in the vertical direction more precise and smooth. Improve the accuracy of the test results. In addition, the integration of the guiding function into the fixed block 331 simplifies the structural design of the entire transmission rod 33, which not only reduces the overall weight of the test fixture, but also reduces the complexity and cost of manufacturing and maintenance.

[0054] See also Figure 3 and Figure 4Specifically, the driving member includes a first driving mechanism 31, a threaded rod 34 and a connecting block 35. A receiving cavity is provided inside the lifting rod 332 along its own axial direction. The threaded rod 34 is arranged in the receiving cavity and connected to the first driving mechanism 31. The connecting block 35 is arranged in the receiving cavity and fixedly connected to the lifting rod 332. A threaded hole is provided at the center of the connecting block 35. The threaded hole is threadedly connected to the threaded rod 34. The first driving mechanism 31 can drive the threaded rod 34 to rotate around its own axis. The threaded rod 34 is driven to rotate by the first driving mechanism 31. The height of the lifting rod 332 can be accurately adjusted by using the threaded fit between the threaded rod 34 and the connecting block 35. This allows the operator to make fine adjustments according to the specific size of the part to be tested to ensure the correct docking between the tester 22 and the part to be tested.

[0055] Furthermore, the first driving mechanism 31 includes a first worm wheel 311, a first worm 312 and a first driving shaft 313. The first worm wheel 311 is connected to the bottom end of the threaded rod 34. The first driving shaft 313 is sleeved with the first worm 312 on its periphery. The first worm 312 is meshed and connected with the first worm wheel 311. The driving member also includes a second driving mechanism 32. The second driving mechanism 32 is connected to the first driving shaft 313 and can drive the first driving shaft 313 to rotate around its own axis. Due to its design characteristics, the worm gear transmission can provide smooth and continuous movement, reduce vibration during movement, and has high stability. When in use, the first driving shaft 313 is driven to rotate by the second driving mechanism 32, and the first driving shaft 313 rotates around its own axis, thereby driving the first worm 312 to rotate synchronously. The first worm 312 rotates, thereby driving the first worm wheel 311 meshing therewith to rotate, and further driving the threaded rod 34 meshing with the first worm wheel 311 to rotate. Since the threaded rod 34 is threadedly connected to the connecting block 35, the rotation of the threaded rod 34 can drive the connecting block 35 to rise or fall along the axis of the threaded rod 34; since the connecting block 35 is fixedly connected to the lifting rod 332, the movement of the connecting block 35 drives the lifting rod 332 to move, and finally drives the movable plate 21 connected to the lifting rod 332 to rise or fall.

[0056] Furthermore, the second drive mechanism 32 includes a second worm wheel 321, a second worm 322, a second drive shaft 323 and a second drive motor 324, the outer periphery of the second drive shaft 323 is provided with a second worm 322, the second drive shaft 323 is connected to the motor shaft of the second drive motor 324, the second worm wheel 321 is connected to the first drive shaft 313, and is meshed with the second worm 322, and the second drive motor 324 can drive the second worm 322 to rotate along its own axis. The cooperation of the second worm wheel 321 and the second worm 322 has a higher reduction ratio, so that the rotation speed of the driven threaded rod 34 is lower, thereby realizing fine adjustment ability. In addition, the self-locking ability of the worm gear transmission mechanism provides a stronger position holding ability for the whole system, even when the power is disconnected or the machine stops suddenly, the system can keep the current position unchanged, and prevent damage to the test piece due to accident. The second drive motor 324 makes the control of the whole system more flexible, and can realize accurate control through programming, improves the automation and efficiency of the test process, and reduces the work intensity of the operator. The motor is a commonly used driving device in this field, and the specific structure and working principle of the second drive motor 324 will not be repeated here. In other embodiments, the second drive motor 324 can also be selected from the cylinder 301, the hydraulic rotary motor, etc., which are not limited here. When in use, the second drive motor 324 is started, and the second drive motor 324 drives its own motor shaft to rotate, and the motor shaft drives the second drive shaft 323 connected thereto to rotate, and the second drive shaft 323 rotates so that the second worm 322 arranged on its periphery also rotates synchronously, and the second worm 322 rotates to drive the second worm wheel 321 meshing therewith to rotate, and then drives the first drive shaft 313 meshing with the second worm wheel 321 to rotate.

[0057] In this embodiment, there are four transmission rods 33, which are distributed at the four corners of the rectangle and are arranged between the support base plate 11 and the movable plate 21. The four rotating rods are grouped in pairs. On the two transmission rods 33 of the same group, a first worm gear 311 is arranged at the bottom of the threaded rod 34 corresponding to each transmission rod 33. The two first worm gears 311 are meshed with a first worm 312, thereby driving a first worm 312 to rotate, which can synchronously drive the two first worm gears 311 to rotate, thereby synchronously driving the two threaded rods 34 to rotate, thereby driving the two lifting rods 332 to lift. Each group of first worm 312 is connected to a second worm gear 321, and the two second worm gears 321 of the two groups of second worm 322 are meshed with a second worm 322, thereby driving a second worm 322 to rotate, which can drive the two first worm 312 to rotate, which can drive the four threaded rods 34 to rotate, and can drive the four lifting rods 332 to lift. One moving plate 21 is driven by four lifting rods 332, thereby improving the driving efficiency and having higher stability. When in use, one second driving motor 324 can drive the four lifting rods 332 to rise and fall synchronously, which not only improves the operating efficiency but also improves the uniformity. The four lifting rods 332 move synchronously, making the movement of the moving plate 21 more stable. In other embodiments, each group may also be provided with three, four or other multiple transmission rods 33, and the same second worm 322 may also be connected to three, four or other multiple transmission rods 33, which is not limited here.
