Description

Technical Field

[0001] The present application relates to the technical field of circuit board processing, and particularly to a positioning device and a testing device. Background Art

[0002] At present, in order to meet the usage requirements of various electronic devices, circuit boards are designed in various different specifications. For example, they are designed as flexible printed circuit boards (PCB soft boards). A PCB soft board is a circuit board that can be moderately bent. With the characteristic of the bendable circuit board, the PCB soft board can be installed at the bent position of the device and still have good functions.

[0003] In the production of PCB soft boards, it is necessary to test their qualification rate. Existing testing fixtures usually clamp and position the PCB soft boards, and then connect the PCB soft boards to the test board through wire harnesses for functional testing. However, during the testing process, the PCB soft boards are pressed by the testing fixtures, which easily causes the PCB soft boards to deform or bend, failing to meet the product factory requirements, resulting in a decrease in the product qualification rate and an increase in production costs. Summary of the Invention

[0064] Based on the background technology, PCB flexible boards are widely used in mobile phone motherboards, computer motherboards, electronic control devices and communication devices, and the industrial output value scale is large. However, PCB flexible boards are prone to deformation during the testing process, failing to meet the product factory requirements, resulting in a decrease in the product qualification rate and an increase in production costs.

[0065] In view of this, the present application provides a positioning device and a testing device. The testing device is used to test the PCB flexible board positioned by the positioning device. The positioning device can perform multi-directional positioning on the PCB flexible board during the testing process of the testing device on the PCB flexible board, prevent the PCB flexible board from deforming, thereby improving the product qualification rate and reducing the production cost.

[0066] Please refer to Figure 1 , the positioning device 100 provided by the embodiment of the present application is used to position the PCB flexible board F. The PCB flexible board F includes a first bending portion F1 and a second bending portion F2 that are connected to each other.

[0067] Specifically, the positioning device 100 includes a carrier plate 10, a first positioning mechanism 20, a second positioning mechanism 30, and a third positioning mechanism 40. The first positioning mechanism 20 includes a movable block 21, a resisting component 22, and a movable component 23. The resisting component 22 and the movable component 23 are arranged on the carrier plate 10. The movable block 21 and the resisting component 22 are arranged at intervals along a first direction X (the direction extending along the X axis). The movable block 21 is connected to the movable component 23, and the movable block 21 can move relative to the resisting component 22 along the first direction X under the drive of the movable component 23. The second positioning mechanism 30 includes an adsorption portion 31. The adsorption portion 31 is arranged on the carrier plate 10. The adsorption portion 31 is used to adsorb the PCB flexible board F. The third positioning mechanism 40 includes a hook block 41, a limiting block 42, and a driving component 43. The driving component 43 is arranged on the carrier plate 10. The hook block 41 is movably arranged on one side of the adsorption portion 31, and the hook block 41 can move relative to the adsorption portion 31 along a second direction Y (the direction extending along the Y axis) under the drive of the driving component 43. The limiting block 42 is arranged on the top of the adsorption portion 31, and the limiting block 42 can move relative to the adsorption portion 31 along the second direction Y under the drive of the driving component 43.

[0068] Among them, in the initial state of the positioning device 100, the first bending portion F1 is located between the movable block 21 and the resisting component 22, and the second bending portion F2 is located on one side of the adsorption portion 31, as Figure 2 shown. The movable block 21 drives the first bending portion F1 to move along the first direction X close to the resisting component 22 under the drive of the movable component 23, so as to clamp the first bending portion F1 under the resisting action of the resisting component 22. While the first bending portion F1 moves along the first direction X, it drives the second bending portion F2 to move along the first direction X close to the hook block 41. The adsorption portion 31 adsorbs the second bending portion F2. The hook block 41 drives close to the adsorption portion 31 under the drive of the driving component 43, so as to clamp the end of the second bending portion F2 under the resisting action of the adsorption portion 31. The limiting block 42 extends out of the adsorption portion 31 under the drive of the driving component 43, so as to press against the top of the second bending portion F2 (as Figure 3 shown).

[0069] In the above embodiments, first, the movable block 21 clamps the first bent portion F1 under the abutting action of the abutting component 22, realizing the positioning of the flexible PCB F in the first direction X. Then, the adsorption portion 31 adsorbs the second bent portion F2, and the hook block 41 clamps the second bent portion F2 under the abutting action of the adsorption portion 31, realizing the positioning of the flexible PCB F in the second direction Y. Finally, the limiting block 42 presses against the top of the second bent portion F2, realizing the positioning of the flexible PCB F in the third direction Z (the direction extending along the Z-axis). Based on this, the positioning device 100 realizes multi-directional positioning of the flexible PCB F, and can effectively prevent the flexible PCB F from deforming.

[0070] In an embodiment of the present application, the hook block 41 is arranged in an "L" shape, and can abut against the side surface of the second bent portion F2 while abutting against the end portion of the second bent portion F2, and can more stably position the end portion of the second bent portion F2, effectively preventing the second bent portion F2 from deforming.

[0071] Combined with Figure 1 As shown, in an embodiment of the present application, the carrier plate 10 can be divided into a first carrier plate 11 and a second carrier plate 12, and the first carrier plate 11 and the second carrier plate 12 are arranged side by side in the first direction X. The first positioning mechanism 20 is installed on the first carrier plate 11, and the second positioning mechanism 30 is installed on the second carrier plate 12, which is convenient for adjusting the installation positions of the first positioning mechanism 20 and the second positioning mechanism 30 according to the bending part of the flexible PCB F, facilitating disassembly and flexible assembly.

[0072] Combined with Figure 4 As shown, in an embodiment of the present application, a plurality of adsorption holes 311 are provided at corresponding positions of the adsorption portion 31. The adsorption portion 31 contacts the second bent portion F2 through the plurality of adsorption holes 311 to realize the adsorption of the second bent portion F2, and further realize the positioning of the flexible PCB F in the second direction Y.

[0073] Combined with Figures 1-3 As shown, in an embodiment of the present application, the second bent portion F2 has a through hole F21. The positioning device 100 further includes a positioning column 50 and a first driving member 51. The first driving member 51 is installed on the carrier plate 10. The positioning column 50 penetrates through the adsorption portion 31 in the second direction Y. The positioning column 50 is connected to the first driving member 51. The positioning column 50 moves relative to the adsorption portion 31 in the second direction Y under the drive of the first driving member 51 to penetrate through the through hole F21. In an embodiment of the present application, the first driving member 51 includes a telescopic cylinder.

[0074] In the above embodiments, the positioning post 50 is driven by the first driving member 51 to move, which can improve the automation level of the positioning device 100. The positioning post 50 passes through the through hole F21 on the flexible PCB F to achieve rough positioning of the flexible PCB F and ensure the accuracy of aligning the flexible PCB F with the area to be tested of the testing device.

[0075] In an embodiment of the present application, the second positioning mechanism 30 further includes a positioning block 32. The positioning block 32 is disposed on the carrier plate 10. The adsorption portion 31 and the positioning block 32 are spaced apart along the second direction Y (the direction extending along the Y axis). A positioning hole 321 is provided on the positioning block 32. The positioning hole 321 is arranged side by side with the positioning post 50 along the second direction Y. After the positioning post 50 passes through the through hole F21, it is inserted into the positioning hole 321.

[0076] In the above embodiments, the positioning block 32 plays a supporting role for the positioning post 50 to ensure the stability of the movement process of the positioning post 50 and prevent it from colliding with the second bending portion F2 and causing damage to the second bending portion F2.

[0077] Combined Figure 4 As shown in the figure, in one embodiment of the present application, the driving assembly 43 further includes a connecting rod 430, a first connecting shaft 44 and a second connecting shaft 45. The connecting rod 430 is rotatably disposed on the top of the adsorption portion 31. The connecting rod 430 includes a first end 431 and a second end 432. The first connecting shaft 44 is rotatably connected to the first end 431. The limiting block 42 is disposed at the end of the first connecting shaft 44 away from the first end 431. The second connecting shaft 45 is rotatably connected to the second end 432. The hook block 41 is disposed at the end of the second connecting shaft 45 away from the second end 432. In an embodiment of the present application, the connecting rod 430 is rotatably mounted on the top of the adsorption portion 31 by a pin.

[0078] In the above embodiments, the linkage of the hook block 41 and the limiting block 42 is realized by the rotation of the connecting rod 430, which can simultaneously realize the positioning of the top and side surfaces of the second bending portion F2.

[0079] In one embodiment of the present application, the driving assembly 43 further includes a second driving member 46. The second driving member 46 is mounted on the carrier plate 10. The second driving member 46 is connected to the second connecting shaft 45. The second connecting shaft 45 moves relative to the adsorption portion 31 in the second direction Y under the drive of the second driving member 46. While moving, the second connecting shaft 45 drives the connecting rod 430 to rotate. While rotating, the connecting rod 430 drives the first connecting shaft 44 to move in the opposite direction of the second direction Y, so that the limiting block 42 extends out of the adsorption portion 31. In an embodiment of the present application, the second driving member 46 may include a telescopic cylinder.

[0080] In the above embodiments, the second driving member 46 drives the second connecting shaft 45 to move. The second connecting shaft 45 drives the limiting block 42 to extend from the adsorption portion 31, so that the limiting block 42 presses against the top of the second bending portion F2. The second connecting shaft 45 moves synchronously with the first connecting shaft 44 through the connecting rod 430. The first connecting shaft 44 drives the hook block 41 to approach the adsorption portion 31, so that the hook block 41 hooks the end of the second bending portion F2, realizing the automation of positioning and ensuring the stability of positioning at the same time.

[0081] In one embodiment of the present application, the movable assembly 23 includes a fixed block 231 and a push shaft 232. The fixed block 231 is arranged on the bearing plate 10. A moving hole (not shown in the figure) is arranged on the fixed block 231. The push shaft 232 penetrates the moving hole along the first direction X. The movable block 21 is arranged at the end of the push shaft 232 close to the abutting assembly 22. The push shaft 232 moves relative to the fixed block 231 along the first direction X under the drive of an external force. For example, the external force can be the driving force of a driving member.

[0082] In the above embodiments, the push shaft 232 is used to push the movable block 21 to move. The fixed block 231 bears and limits the push shaft 232 to ensure the stability of the movement of the movable block 21.

[0083] In one embodiment of the present application, the movable assembly 23 further includes an elastic member 233. The elastic member 233 is sleeved on the push shaft 232. Two ends of the elastic member 233 respectively abut against the fixed block 231 and the movable block 21. In one embodiment of the present application, the elastic member 233 includes a compression spring.

[0084] In the above embodiments, the elastic member 233 has a certain elasticity and can play a certain buffering role in the process of the movable block 21 pushing the PCB flexible board F to move, thereby avoiding the movable block 21 from excessively squeezing the first bending portion F1 and causing damage to the first bending portion F1.

[0085] In one embodiment of the present application, the movable assembly 23 further includes a third driving member 235. The third driving member 235 is connected to the end of the push shaft 232 far from the abutting assembly 22. The third driving member 235 is used to drive the push shaft 232 to move relative to the fixed block 231. In one embodiment of the present application, the third driving member 235 may include a telescopic cylinder.

[0086] In the above embodiments, by driving the push shaft 232 to move through the third driving member 235, the accuracy of the moving distance of the movable block 21 can be improved, thereby avoiding the movable block 21 from excessively squeezing the first bending portion F1 and causing damage to the first bending portion F1.

[0087] In one embodiment of the present application, the movable component 23 further includes a limiting member 234. The limiting member 234 is installed at the end of the pushing shaft 232 away from the abutting component 22. In one embodiment of the present application, the limiting member 234 includes a limiting nut.

[0088] In the above embodiment, when the pushing shaft 232 moves a certain distance, the limiting member 234 abuts against the side of the fixed block 231 opposite to the movable block 21, which can limit the pushing shaft 232 and prevent the pushing shaft 232 from driving the movable block 21 to move excessively, thereby avoiding excessive extrusion of the first bending portion F1 by the movable block 21 and causing damage to the first bending portion F1.

[0089] In one embodiment of the present application, the abutting component 22 includes a first abutting block 221, a second abutting block 222, and a third abutting block 223. The first abutting block 221 is arranged on the carrier plate 10 along the second direction Y. The second abutting block 222 is arranged on the carrier plate 10 along the first direction X and is vertically connected to the first abutting block 221. The third abutting block 223 is arranged on the carrier plate 10 along the first direction X. The third abutting block 223 is arranged opposite to the second abutting block 222.

[0090] In the above embodiment, the first bending portion F1, the second bending portion F2, and the connection between the first bending portion F1 and the second bending portion F2 are positioned by the first abutting block 221, the second abutting block 222, and the third abutting block 223, preventing the PCB flexible board F from deforming when the movable block 21 moves the PCB flexible board F.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit them. Although the present application has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
