Abstract
Description
Technical Field
[0001] The invention relates to the field of circuit board detection, and in particular to a clamping plate module for a flying probe tester. Background Art
[0002] The backlight is a light source device used to ensure that the back of the LCD screen emits light. Its main structure is to densely arrange lamp beads on the circuit board. During the production process, the circuit board needs to set corresponding circuits and lamp bead connection holes on the board according to the actual size of use. Since the lamp beads of the backlight are extremely small, the number of lamp beads that need to be arranged on the circuit board is also extremely large. Usually, there are more than 200,000 connection points on an uncut circuit board. When performing flying probe testing, it takes up to dozens of hours to complete. If an abnormality is reported during the test, a second retest is required. For other areas that have tested well, they cannot be removed. The circuit board needs to wait until the test of the abnormal area is completed before the circuit board can be removed.
[0003] In response to the above problems, existing production personnel directly cut the raw board into the size that meets the use, so that the test time of a single board can be effectively reduced. However, there are some usage defects when testing with a flying probe tester. The circuit board that has not been cut is a single piece and can be directly clamped and fixed by the movable clamp on the flying probe tester along the edges. The circuit board after cutting is reduced in size and needs to be placed side by side between two movable clamps for fixing together during testing. When conducting multiple tests, if one or more of the boards are abnormal, it is still necessary to wait for the tests of other boards to be completed before the tested good products can be removed and the abnormal boards can be retested. During this process, it is necessary to manually record which board has reported the error. Therefore, in the process of testing small boards, a large number of small boards cannot be tested at one time, and the number of small board tests needs to be controlled. Summary of the invention

It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. Additionally, it should be noted that for the convenience of description, only the parts related to the present application rather than all the structures are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.
[0030] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection, an electrical connection, or a connection capable of mutual communication; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.
[0031] Embodiment 1: The present invention specifically provides a clamping plate module for a flying probe tester, as Figure 1-Figure 9As shown, it includes: a bidirectional transmission driving device 11, the driving device 11 includes: an outer frame 111 for installation on the flying probe device, when in use, the driving device 11 needs to be installed in the test area of the flying probe tester, the outer frame 111 is symmetrically provided with two, respectively on both sides of the test area, two first screw rods 112 are rotatably installed in the outer frame 111, and first motors 113 are installed on both sides of the two outer frames 111. The two first motors 113 on the outer frames 111 respectively drive two different first screw rods 112 to rotate, and the two ends of the first movable plate 12 are connected to the first screw rods 112 on both sides, and the two ends of the second movable plate 13 are also connected to the first screw rods 112 on both sides. Since two first screw rods 112 are respectively provided on both sides, a total of four are provided, and the four first screw rods 112 are grouped in pairs, and respectively drive the first movable plate 12 and the second movable plate 13 to move, so as to realize that the first movable plate 12 and the second movable plate 13 can each slide as needed, and achieve the effect of approaching and moving away from each other. A clamping module 21 is installed on the first movable plate 12 and the second movable plate 13. A plurality of movable clamping units 22 are arranged on the clamping module 21. The movable clamping units 22 work independently of each other. The movable clamping units 22 are provided with movable free clamping ends. The plate to be clamped is placed between the first movable plate 12 and the second movable plate 13. The two ends of the plate are clamped and kept fixed by the movable clamping units 22 on the upper and lower sides. When a plate is detected to be abnormal, one of the free clamping ends corresponding to the two ends of the plate releases the clamped plate and makes the plate pop out in an inclined state.
[0032] according to Figure 1 and Figure 2 As shown, an electronic screen 51 is installed on the second movable plate 13 according to the number of movable clamping units 22. When a plate is detected to be abnormal and is released and ejected by the movable clamping unit 22, a striking prompt message can be displayed on the electronic screen 51 accordingly to mark the error plate.
[0033] Since there are multiple active clamping units 22, and the active clamping units 22 work independently of each other, and the sizes of the test plates are different, the number of active clamping units 22 required will also be different, so it is necessary to cooperate with the system of the flying probe tester to achieve the clamping of plates of different sizes; The first step is to bind the movable clamping units 22 aligned with each other in the upper and lower positions into one group in the system, and the multiple groups are numbered and arranged in sequence; The second step is to input the plate size information into the test system, match the plate width according to the maximum clamping width of a single group of active clamping units 22, and match the plate with a corresponding number of active clamping units 22. For example, if the plate width is within the maximum clamping range of a single group of active clamping units 22, one group is called to clamp the plate; if the plate width is within the maximum clamping range of two groups of active clamping units 22, two groups are called to clamp both ends of the plate, and so on; The third step is to release the plate after clamping by its matching corresponding active clamping unit 22. Specifically, when the flying probe tester detects the plate and the corresponding plate detection reports an error, the corresponding active clamping unit 22 releases the clamped plate, so that the detection plate body pops up in a tilted state. The tilted state means that one of the two active clamping units 22 that clamp the plate no longer clamps the end of the plate, while the other end still clamps the plate and slightly deflects it, so that the plate is in a tilted state, thereby showing a different state from other good boards on the flying probe tester.
[0034] After the plate is detected and an error is reported, the movable clamping unit 22 makes the plate pop out. After the plate is popped out, the plate can be taken away and retained in the re-test area for a second re-test. Other plates that have been tested or not are still kept in the clamped state and when all the plates have been tested, the first movable plate 12 and the second movable plate 13 are separated from each other, and the plate on the first movable plate 12 is also clamped in a vertical state.
[0035] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 5 and Figure 6 As shown, the movable clamping unit 22 includes: a fixed shaft 31 installed in the clamping module 21, a plurality of clamping wheels 32 are rotatably installed on the fixed shaft 31, the plurality of clamping wheels 32 are rotatably connected in series on the fixed shaft 31, the clamping wheels 32 can rotate independently of each other, a clamping groove 321 for clamping the plate is opened on the clamping wheel 32, the end of the plate is clamped and fixed by the clamping groove 321, a protruding and extending swinging part 33 is provided on the side of the clamping wheel 32 opposite to the clamping groove 321, the swinging part 33 is moved to realize the rotation of the clamping wheel 32 on the fixed shaft 31, and a pulling device is installed in the clamping module 21, the pulling device is used to pull the swinging part 33 to swing.
[0036] Specifically, when the movable clamping units 22 are distributed at two positions, the first movable plate 12 and the second movable plate 13, one of the clamping grooves 321 at the two positions is a clamping groove that allows the plate to be inserted. The clamping groove has a certain depth. After the end of the plate is inserted into the clamping groove, it can remain in a fixed state. The clamping groove 321 at the other position is an anti-deflection groove that can just rest against the edge of the plate without performing a clamping operation. The function of the anti-deflection groove is to rest against the other end of the clamped plate to keep it fixed. When in use, the angles of the anti-deflection groove and the clamping groove must be aligned. The two movable clamping units 22 approach each other and clamp the plate firmly. Therefore, when a plate error occurs during the detection process, the clamping wheel 32 with the anti-deflection groove can be deflected to one side, so that the clamped plate will be detached and popped out of the anti-deflection groove. After detachment, the clamping wheel 32 with the clamping groove pulls the swing part 33 through the pulling device to deflect, and finally the plate is tilted.
[0037] like Figure 5 and Figure 6 As shown, the pulling device includes: an electromagnet 34, which is installed in the clamping module 21 according to the number of the movable clamping units 22. An iron core 36 is slidably penetrated on the electromagnet 34, and a spring 35 is sleeved between the iron core 36 and the electromagnet 34. The spring 35 keeps the iron core 36 in a popped-out state. A pull rod 37 is installed at the end of the iron core 36, and both ends of the pull rod 37 are connected to the swinging part 33. After the electromagnet 34 is energized, it attracts the iron core 36 and then moves with the pull rod 37. At this time, the swinging part 33 moves with it. In this way, the swinging part 33 is swung. After the electromagnet 34 is powered off, the spring 35 restores the swinging part 33 to its original position.
[0038] like Figure 5 and Figure 6 As shown, a movable groove 371 is formed on the swinging part 33, and the ends of the pull rod 37 are movable within the range of the movable groove 371. When the pull rod 37 pulls the swinging part 33, there will be a positional offset between the connection points of the swinging part 33 and the pull rod 37, so it is necessary to make the pull rod 37 have a certain range of motion on the swinging part 33, and the function of the movable groove 371 is to provide the pull rod 37 with a certain range of motion.
[0039] like Figure 5 and Figure 6As shown in the figure, it further includes: a backing plate 38 installed on one side inside the clamping module 21, with the end of the backing plate 38 abutting against the swinging part 33. When the swinging part 33 contacts the backing plate 38, the clamping groove 321 of the clamping wheel 32 is in a horizontal and vertical state. The function of the backing plate 38 is to assist the swinging part 33 in correcting to a vertical state, so that the clamping groove 321 on the clamping wheel 32 can be kept in a vertical state; filling blocks 39 are symmetrically installed inside the clamping module 21, distributed on both sides of the clamping wheel 32, and fitting with the outer curved surface of the clamping wheel 32, so as to fill the gap between the clamping wheel 32 and the clamping module 21 through the filling blocks 39; a soft rubber layer 310 is provided on the surface of the clamping groove 321. Under the action of the soft rubber layer 310, when the plate is inserted into the clamping groove 321, a softer and friction-providing clamping effect can be provided. In this way, when the plate pops out, one end of the plate can still be stable in the clamping groove 321 and will not fall on the testing equipment.
[0040] Embodiment 3: On the basis of Embodiment 1, as Figure 1 , Figure 7-Figure 9 shown, the movable clamping unit 22 includes: a U-shaped top plate 47 arranged and installed inside the clamping module 21. One side of the U-shaped top plate 47 is fixedly installed with the clamping module 21, and the connection part is the fixed part of the U-shaped top plate 47. There is a slit 474 left between the other side and the clamping module 21. The part of the U-shaped top plate 47 close to the slit is the movable part. Therefore, when pulling the movable part towards the fixed part, the area of the bottom of the U-shaped top plate 47 close to the movable part will bend upwards. There is a groove 471 on the middle surface of the U-shaped top plate 47. There is a curved surface thickening part 472 on the U-shaped top plate 47 close to the slit 474. The curved surface thickening part 472 can increase the structural strength of the movable part. The function of the curved surface thickening part 472 is to prevent the U-shaped top plate 47 from breaking when the movable part is pulled and deformed. There is a protruding fixing rod 473 on the movable part of the U-shaped top plate 47 close to the slit 474; a pulling device for pulling the fixing rod 473 is installed inside the clamping module 21. As the fixing rod 473 is pulled, the movable part bends and deflects in the pulling direction.
[0041] Specifically, during use, the plate is inserted into the groove 471 of the U-shaped top plate 47. The arrangement of the groove 471 can refer to the situation of the clamping groove 321 in Embodiment 2. After the two U-shaped top plates 47 approach each other, the plate can be clamped and kept in a stable state. After the plate detection reports an abnormality, the pulling device is used to first pull the movable part so that the bottom of the U-shaped top plate 47 bends and deforms. In this way, one end of the plate can be separated from the U-shaped top plate 47. After separation, the plate tilts and pops out following the deformation of the other U-shaped top plate 47.
[0042] As Figure 8 and Fig. 9As shown, the pulling device includes: a second motor 41 installed in the clamping module 21. A second lead screw 43 is installed in the clamping module 21. The second lead screw 43 is connected to the second motor 41 through a pulley set 42. A slide 44 is connected to the second lead screw 43. The second lead screw 43 enables the slide 44 to move within the clamping module 21. A telescopic push block 45 is fixedly installed at the bottom of the slide 44. A collar 461 is installed on the movable rod 46 of the telescopic push block 45. When the collar 461 moves with the slide 44, it can slide and be stuck on the fixed rod 473 at the corresponding position of the U-shaped top plate 47.
[0043] Specifically, when in use, when the movable part of the U-shaped top plate 47 needs to be pulled, the slide 44 moves to the corresponding area. After the collar 461 engages with the fixed rod 473, the telescopic push block 45 pulls the movable part to move, thereby realizing the deformation of the U-shaped top plate 47.
[0044] As Figure 8 and Fig. 9 As shown, it further includes: a first limiting plate 48 installed on one side inside the clamping module 21, and a second limiting plate 49 is installed on the other side inside the clamping module 21. The tops of the first limiting plate 48 and the second limiting plate 49 are both in sliding contact with the edge part 441 of the slide 44. The bottom of the first limiting plate 48 can be in contact with the top edge of the movable bending side of the U-shaped top plate 47. After the tops of the first limiting plate 48 and the second limiting plate 49 abut against the bottom of the slide 44, the stability of the movement of the slide 44 can be ensured. And the bottom of the first limiting plate 48 can be in contact with the top of the U-shaped top plate 47 and the movable part, so that the U-shaped top plate 47 will not have a large deformation when pressing the plate.
[0045] It can be imagined that when multiple U-shaped top plates 47 need to be pulled simultaneously, it is impossible to realize simultaneous pulling by using a single slide 44 with a telescopic push block 45 to pull the U-shaped top plate 47. Therefore, the number of telescopic push blocks 45 can be set to be the same as the number of U-shaped top plates 47, that is, the telescopic push blocks 45 are installed in the clamping module 21 according to the number of U-shaped top plates 47.
[0046] It is also conceivable that the corresponding movable clamping units 22 on the first movable plate 12 and the second movable plate 13 can be combined by using respective parts of Embodiment 3 and Embodiment 2. That is, the movable clamping unit 22 installed on the first movable plate 12 is driven by an electromagnet 34 to rotate the clamping wheel 32, and the U-shaped top plate 47 of this embodiment is installed on the second movable plate 13. When specifically used in this way, the sheet is inserted into the clamping groove 321 of the clamping wheel 32, and then the other end of the sheet is抵住 by the groove 471 of the U-shaped top plate 47 to firmly clamp the sheet. When it is necessary to eject the defective sheet, first pull the U-shaped top plate 47 to deform and separate from the end of the sheet, and then deflect the clamping wheel 32 to tilt the sheet. The advantage of this method is that when the sheet deflects, the sheet can be tilted by rotating the clamping wheel 32, and it is not necessary to hard-pull and deform like the U-shaped top plate 47 to tilt the sheet. And the place where the other end of the sheet is抵住 is抵住 by the U-shaped top plate 47, so the clamping and fixing effect of the end of this part of the sheet will have a better supporting effect than the clamping wheel 32, and the problem that the sheet deflects by itself during the test will not occur because of the clamping wheel 32.
[0047] The above-described embodiments only represent the preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements, and substitutions can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
