[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0037] It should be noted that the terms "first" and "second" in this application are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first" and "second" can explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.
[0038] It should be noted that, in the present application, downward refers to the direction of gravity, and upward refers to the opposite direction of gravity.
[0039] In the prior art, there are two situations for testing display screens. One is that the display surface of the display screen and the connection port of the flexible circuit board are on opposite sides, that is, the display surface of the display screen faces upward, and the connection port of the flexible circuit board of the display screen faces downward. The corresponding probe of the crimping device needs to face upward so that the connection port and the probe can be crimped. In this case, even if the flexible circuit board is warped, the connection success rate is very high after the pressure plate of the crimping device is pressed together. The other is that the display surface of the display screen and the connection port of the flexible circuit board are on the same side, that is, the display surface of the display screen faces upward, and the connection port of the flexible circuit board of the display screen faces upward. The corresponding probe of the crimping device needs to face downward so that the connection port and the probe can be crimped. In this case, once the flexible circuit board is warped, the possibility of connection failure is very high.
[0040] See also Figure 1 , Figure 2 and Figure 3 The present application provides a crimping device 10, which includes a carrier 110, a crimping mechanism 120 and a flipping mechanism 130. The carrier 110 is used to load a display screen 101 bonded with a flexible circuit board 102, wherein when the display screen 101 is loaded on the carrier 110, a free end A of the flexible circuit board 102 extends outside the carrier 110; the crimping mechanism 120 is used to crimp the free end A of the flexible circuit board 102 to input an electrical signal to the flexible circuit board 102; and the flipping mechanism 130 is connected to the carrier 110 and is used to drive the carrier 110 to flip relative to the crimping mechanism 120.
[0041] Specifically, the display screen 101 bonded with the flexible circuit board 102 is placed on the loading surface F of the carrier 110, but the free end A of the flexible circuit board 102 is not placed on the loading surface F. The free end A extends out of the loading surface F of the carrier 110. The free end A is provided with a connection port 1021, which needs to contact the probe 1201 on the crimping mechanism 120. The electrical signal is input to the flexible circuit board 102 through the probe 1201, so that the display screen 101 can be tested. Figure 1 , Figure 2 and Figure 3 Three different states of the display screen 101 bonded with the flexible circuit board 102 on the crimping device 10 are shown respectively. Figure 1 In the figure, the loading surface F of the carrier 110 is facing upward, that is, the display surface of the display screen 101 is facing upward, the connection port 1021 of the flexible circuit board 102 is also facing upward, and the probe 1201 of the crimping mechanism 120 is also facing upward. Since the connection port 1021 and the probe 1201 are facing the same direction, crimping cannot be performed for testing. Figure 2 ,exist Figure 1 On the basis of the above, the carrier 110 is flipped by the flipping mechanism 130, and the loading surface F of the carrier 110 is turned downward, and the connection port 1021 of the flexible circuit board 102 is also turned downward. Since the connection port 1021 and the probe 1201 are facing opposite directions, the connection port 1021 and the probe 1201 can be pressed to make them contact and realize electrical connection. Figure 2 In the embodiment, the display screen 101 faces downward, which makes it difficult to observe the display effect of the display screen 101. Figure 3 ,exist Figure 2 On the basis of this, the carrier 110 and the crimping mechanism 120 are flipped together by the flipping mechanism 130. At this time, the loading surface F of the carrier 110 will face upward due to the flipping, and the display surface of the display screen 101 will also face upward. In this way, the display effect of the display screen 101 during the test can be observed.
[0042] Different from the prior art, the crimping device 10 of the present application includes a carrier 110, a crimping mechanism 120 and a flipping mechanism 130. The flipping mechanism 130 is connected to the carrier 110. After the carrier 110 is turned over by the flipping mechanism 130, the connection port 1021 of the flexible circuit board 102 is opposite to the probe 1201 of the crimping mechanism 120, so that crimping can be performed. At the same time, the connection port 1021 is turned downward by flipping and crimped with the upward-facing probe 1201. Compared with the prior art, when the connection port is facing upward, the crimping device with the probe facing downward is used for crimping. The success rate of crimping in the present application is much higher than the success rate of crimping in the prior art.
[0043] In one embodiment, see Figure 4 and Figure 5 The crimping device 10 further includes a base 140 and a lifting mechanism 150. The base 140 is used to carry the carrier 110 and the crimping mechanism 120; the lifting mechanism 150 is connected to the flip mechanism 130 and the carrier 110, and is used for the carrier 110 and the flip mechanism 130 to perform lifting and lowering movements relative to the base 140.
[0044] Specifically, the base 140 is used to support the carrier 110 and the crimping mechanism 120 to ensure that the relative height of the carrier 110 and the crimping mechanism 120 is a fixed value, thereby ensuring the crimping effect. The lifting mechanism 150 is connected to the flipping mechanism 130 and the carrier 110, so that the flipping mechanism 130 can be lifted and lowered relative to the base 140, and the carrier 110 can also be lifted and lowered relative to the base 140. It can be understood that when the flipping mechanism 130 flips the carrier 110, it is necessary to first lift the carrier 110 through the lifting mechanism 150 so that the carrier 110 is away from the base 140, so that when the carrier 110 flips, there is no possibility of collision with the base 140. After the flipping mechanism 130 flips the carrier 110, the lifting mechanism 150 drives the carrier 110 to descend so that the carrier 110 is close to the base 140, so that the base 140 can support the carrier 110.
[0045] In one embodiment, see Figure 5 and Figure 6 The base 140 is provided with a plurality of limiting grooves W, and the carrier 110 and the crimping mechanism 120 are limited in different limiting grooves W.
[0046] Specifically, a plurality of limiting grooves W are provided on the base 140, and the limiting grooves W limit both the carrier 110 and the crimping mechanism 120 to fixed positions, so that the relative positions of the carrier 110 and the crimping mechanism 120 can be fixed, thereby ensuring the position accuracy of crimping. It should be noted that the limiting grooves W can be provided on the base 140 to limit the crimping mechanism 120 in both the unflipped position and the position after flipping together with the carrier 110.
[0047] Of course, in some other embodiments, the base 140 may be provided with a limiting column, and the carrier 110 and the crimping mechanism 120 are limited by the limiting column. The present application does not impose any specific restrictions on the specific limiting method.
[0048] In one embodiment, see Figure 4 and Figure 7 A supporting portion 111 is further protruded on the loading surface F of the carrier 110 , and the supporting portion 111 is used to support the carrier 110 after the carrier 110 is flipped so that the loading surface F of the carrier 110 faces the base 140 .
[0049] Specifically, Figure 7 yes Figure 4 The structural diagram of the middle carrier 110 being turned over and placed on the base 140 , the support portion 111 can prevent the display surface of the display screen 101 from directly contacting the carrier 110 , thereby avoiding scratches on the surface of the display screen 101 .
[0050] In one embodiment, see Figure 4 and Figure 5 The flipping mechanism 130 includes a motor 131 and a flipping shaft 132 . The flipping shaft 132 is connected to the carrier 110 . The motor 131 is connected to the flipping shaft 132 . The motor 131 is used to drive the flipping shaft 132 to flip.
[0051] Specifically, the flip shaft 132 is connected to the carrier 110, and the flipping of the flip shaft 132 drives the carrier 110 to flip. The motor 131 is connected to the flip shaft 132, and the motor 131 can be set at either end of the flip shaft 132 as long as it can drive the flip shaft 132 to rotate.
[0052] In one embodiment, see Figure 5 The flip shaft 132 is disposed in the carrier 110. This ensures that the entire carrier 110 is more stable when flipped. Of course, in some other embodiments, the flip shaft 132 can also be welded and fixed to the side wall of the carrier 110.
[0053] In one embodiment, see Figure 8 The crimping device 10 further includes a connecting mechanism 160 , which is used to fix the carrier 110 and the crimping mechanism 120 after the carrier 110 is flipped to a target state, so that the carrier 110 and the crimping mechanism 120 are flipped synchronously under the drive of the flipping mechanism 130 .
[0054] Specifically, the connection mechanism 160 is disposed in at least one of the carrier 110 and the crimping mechanism 120. When the carrier 110 is flipped to the target state by the flipping mechanism 130, that is, the loading surface F of the carrier faces downward, and the connection port 1021 of the flexible circuit board 102 contacts the probe 1201, the connection mechanism 160 fixes the carrier 110 and the crimping mechanism 120, thereby ensuring the stability between the carrier 110 and the crimping mechanism 120 in the subsequent flipping process of the two together, so as to ensure the crimping effect. The connection mechanism 160 can be by magnetic attraction, or by plugging, or by clamping, and the specific fixing method is not limited.
[0055] In one embodiment, see Figure 8 The connecting mechanism 160 includes a plug portion 161 and an interface portion 162, the plug portion 161 has at least one convex portion, and the interface portion 162 has at least one concave portion, the convex portion matches the concave portion, one of the plug portion 161 and the interface portion 162 is fixed on the carrier 110, and the other is fixed on the crimping mechanism 120, and is used for fixing and connecting the carrier 110 and the crimping mechanism 120 by combining the interface portion 162 and the plug portion 161 after the carrier 110 is flipped to the target state, so that under the drive of the flipping mechanism 130, the carrier 110 and the crimping mechanism 120 are flipped synchronously.
[0056] Specifically, by combining the convex part of the plug part 161 and the concave part of the interface part 162, the carrier 110 and the crimping mechanism 120 can be fixed so that the carrier 110 and the crimping mechanism 120 can be flipped synchronously when the carrier 110 is flipped. The number of the convex part and the concave part is not limited as long as the two match. The specific positions of the plug part 161 and the interface part 162 are not limited as long as one of them is set on the carrier 110 and the other is set on the crimping mechanism 120.
[0057] In one embodiment, see Fig. 9 The loading surface F of the carrier 110 is provided with a receiving groove 112, and the receiving groove 112 includes a first groove 1121 for receiving the limiting display screen 101 and a second groove 1122 for receiving the limiting flexible circuit board 102, wherein the first end D1 of the second groove 1122 is connected to the first groove 1121, and the second end D2 of the second groove 1122 is connected to the side wall of the carrier 110.
[0058] Specifically, the accommodating groove 112 is used to limit the carrier on the carrier 110. Different carriers are designed to be contoured using the accommodating groove 112 to limit different carriers. For example, the accommodating groove 112 includes a first groove 1121 and a second groove 1122. The first groove 1121 is used to place the display screen 101 and limit the display screen 101, and the second groove 1122 is used to place the flexible circuit board 102 and limit the flexible circuit board 102. Since the flexible circuit board 102 is bonded to the display screen 101, the second groove 1122 is connected to the first groove 1121 at the first end D1, and the second end D2 of the second groove 1122 is connected to the side wall of the carrier 110, so that the free end A of the flexible circuit board 102 can extend out of the loading surface F of the carrier 110, so that the connecting port 1021 contacts the probe 1201 of the crimping mechanism 120.
[0059] Of course, in some other implementations, the carrier 110 may not be provided with a receiving groove, and limiting columns may be provided to limit the display screen 101 and the flexible circuit board 102 .
[0060] In one embodiment, a vacuum hole 1123 is provided at the bottom of the receiving groove 112. The vacuum hole 1123 can ensure the flatness of the display screen 101 and the flexible circuit board 102 on the carrier 110 through vacuum adsorption, and can prevent the display screen 101 and the flexible circuit board 102 from falling when flipping through vacuum adsorption.
[0061] In one embodiment, see Fig. 9 and Fig.10 A chamfer structure C is provided on the groove wall of the second end D2 of the second groove 1122 to improve the placement accuracy of the flexible circuit board 102 .
[0062] Specifically, the second groove 1122 is provided with a chamfer structure C on the groove wall near the second end D2. The chamfer structure C can make the free end A easier to lay flat and less likely to warp when the flexible circuit board 102 is placed in the second groove 1122, thereby improving the placement accuracy of the flexible circuit board 102.
[0063] In one embodiment, the chamfered structure C includes a circular chamfered structure. Of course, in some other embodiments, the chamfered structure C may also be an oblique chamfer, as long as it is a chamfered structure.
[0064] In one embodiment, see Fig.11 The crimping device 10 further includes a limiting component 170 , which is protruding from the groove wall of the receiving groove 112 and is used to limit the display screen 101 and the flexible circuit board 102 in the receiving groove 112 .
[0065] Specifically, the limiting component 170 is protruded from the groove wall of the receiving groove 112, so that the limiting component 170 has the function of limiting to one side of the groove based on the groove wall. When the display screen 101 and the flexible circuit board 102 are placed in the receiving groove 112, the limiting component 170 ensures the positioning accuracy by further limiting the display screen 101 and the flexible circuit board 102.
[0066] In one embodiment, see Fig.11 The number of the limiting components 170 is multiple, wherein some of the limiting components 170 are convexly disposed on the groove wall of the first groove 1121, and some of the limiting components 170 are convexly disposed on the groove wall of the second groove 1122. The number of the limiting components 170 can be 2, 3, or 4, and they are disposed in both the first groove 1121 and the second groove 1122, so as to limit the display screen 101 and the flexible circuit board 102.
[0067] Of course, in some other embodiments, the limiting assembly 170 may also be only disposed in the first groove 1121 or the second groove 1122 .
[0068] In one embodiment, see Fig.11 The limiting assembly 170 includes an elastic member 171 and a limiting block 172 . One end of the elastic member 171 is connected to the groove wall of the accommodating groove 112 , and the other end is connected to the limiting block 172 .
[0069] Specifically, the elastic member 171 provides a force in the groove direction to the limit block 172 with the groove wall as the support position, thereby playing the role of limiting and clamping, and during the flipping process of the carrier 110, it can ensure that the display screen 101 and the flexible circuit board 102 are clamped and do not fall. The elastic member 171 includes a spring. In some other embodiments, the elastic member 171 can also be an elastic pad, etc.
[0070] Of course, in some other implementations, the limiting component may also be a driving component, which limits the display screen and the flexible circuit board by moving into the groove.
[0071] In one embodiment, see Fig.12 The crimping mechanism 120 includes a first pressing plate 121 and a second pressing plate 122 ; one end of the second pressing plate 122 is rotatably connected to the first pressing plate 121 , and the other end thereof is provided with a probe 1201 protruding toward the first pressing plate 121 .
[0072] Specifically, the probe 1201 protruding from the second pressing plate 122 is used to contact the connection port 1021 on the flexible circuit board 102. After the contact, the first pressing plate 121 can be rotated relative to one end of the second pressing plate 122 to approach the other end of the second pressing plate 122, so that the connection port 1021 of the flexible circuit board 102 and the probe 1201 of the second pressing plate 122 are pressed more tightly to ensure the pressing effect. The first pressing plate 121 and the second pressing plate 122 can be rotatably connected by a rotating shaft or a hinge.
[0073] In one embodiment, see Fig.12 The crimping mechanism 120 further includes a magnetic member 123, which is disposed in the second pressing plate 122. The magnetic member 123 can have a magnetic attraction on the connection port 1021 of the flexible circuit board 102, so that the connection port 1021 of the flexible circuit board 102 is easily attracted when it is close to the second pressing plate 122, so that the connection port 1021 just corresponds to the probe 1201, thereby improving the crimping accuracy. The magnetic member 123 can be a permanent magnetic material, etc., or an electromagnet, etc.
[0074] The above description is only an embodiment of the present application and does not limit the patent scope of the present application.
