For example, when an element is referred to as being "connected to" another element, it may be directly or indirectly connected to the other element.

[0037] In addition, reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] The embodiment of the present invention provides a FPC test material transport device 100, such as Figure 1 and Figure 2 As shown, the FPC test material transport device 100 includes a first linear motion component 1, a second linear motion component 2, a first lifting component 3, a second lifting component 4 and two supporting members, wherein the first linear motion component 1 and the second linear motion component 2 are arranged in parallel and with a gap. In the extension direction of the first linear motion component 1, the first lifting component 3 is slidably arranged on the first linear motion component 1, and the second lifting component 4 is slidably arranged on the second linear motion component 2. That is, the first lifting component 3 and the second lifting component 4 can both slide back and forth along the extension direction of the first linear motion component 1. Specifically in this embodiment, the extension direction of the first linear motion component 1 is the transmission direction of the FPC 6.

[0039] In order to simplify the structure of the FPC test material transport device 100 and ensure that the entire test process is relatively simple and reliable, between the first linear motion component 1 and the second linear motion component 2, two support members are respectively vertically slidably arranged on the first lifting component 3 and the second lifting component 4, and are arranged parallel to each other and opposite to each other. That is, the two support members are located in the gap between the first linear motion component 1 and the second linear motion component 2. It can be understood that one support member can move up and down under the drive of the first lifting component 3, and the first lifting component 3 can drive the support member connected thereto to move back and forth along the extension direction of the first linear motion component 1 under the drive of the first linear motion component 1. Similarly, the other support member can also move up and down under the drive of the second lifting component 4, and correspondingly, the second lifting component 4 can also move back and forth along the extension direction of the second linear motion component 2 under the drive of the second linear motion component 2 together with the other support member connected thereto. It should be noted that because the first linear motion component 1 and the second linear motion component 2 are parallel to each other, the extension directions of the two are the same direction, which is the transmission direction of the FPC 6.

[0040] Specifically in this embodiment, two support members are used to support the FPC 6 to be transported, that is, one support member is used to support one FPC 6 to be transported, and the other support member is used to support another FPC 6 to be transported, wherein the FPC 6 to be transported here can be an untested FPC 6 or a tested FPC 6. It can be understood that the same FPC 6 before and after the test is transported by the same support member.

[0041] In this embodiment, the two support members can realize staggered movement up and down, so as to replace one of the FPC 6 to be transported with another FPC 6 to be transported in the same station. In other words, one support member can move back and forth along the transmission direction of the FPC 6 and / or move vertically up and down under the drive of the first linear motion component 1 and the first lifting component 3, and the other support member can also move back and forth along the transmission direction of the FPC 6 and / or move vertically up and down under the drive of the second linear motion component 2 and the second lifting component 4.

[0042] Among them, taking the test station (not shown) as an example, in order to avoid the test station being vacant for a long time after the support members in the test station are tested, waiting for the next support member to arrive, before arriving at the test station, the two support members need to complete the positional relationship of the upper and lower arrangements, so as to avoid interference and collision between the two support members, or between the transported FPC 6 and the support members during the interleaving process; when the untested FPC 6 arrives at the same station such as the position corresponding to the test station, the tested FPC 6 can be moved out of the test station under the drive of the corresponding support member, and then, the untested FPC 6 is gradually driven by the corresponding support member to move up and down and accurately arrive at the test station, thereby replacing the tested FPC 6 to continue testing.

[0043] It should be noted that the untested FPC 6 can be accurately shifted to the test station by vertical movement from the position corresponding to the test station after the tested FPC 6 is completely moved out of the test station, or accurately shifted to the test station from the position corresponding to the test station while the tested FPC 6 is gradually moved out of the test station, or directly shifted to the test station by horizontal movement and vertical movement at the same time. Of course, it is not limited to these methods to shift and replace the tested FPC 6 in the test station. The specific method to be adopted needs to be comprehensively considered according to factors such as the time spent in each process. In general, in the present embodiment, the FPC 6 test is mainly achieved by the up and down displacement movement of the two support members, so that the FPC 6 before the test is shifted to the test station to replace the tested FPC 6 in the test station. Of course, from the perspective of the entire material transportation process of the entire FPC test material transportation device 100, the same station is not limited to the test station.

[0044] It should also be noted that, because the transported material is mainly FPC 6, the support member in the present invention can generally be a support plate. Of course, in fact, the transported material can also be other suitable products, and correspondingly, the support member can also adopt other suitable structures.

[0045] In addition, in this embodiment, the loading station (not shown) and the unloading station (not shown) of FPC 6 are located at the same position, that is, after the FPC 6 completes the test, it will continue to be sent back to the loading station by the corresponding support member, and after unloading, the support member can directly load the material to continue to be transported to the testing station.

[0046] In summary, compared with the prior art, the FPC test material transport device 100 has at least the following beneficial effects: the FPC test material transport device 100, through the mutual cooperation between the first linear motion component 1, the second linear motion component 2, the first lifting component 3 and the second lifting component 4, enables the two support members to achieve up and down staggered movement between the first linear motion component 1 and the second linear motion component 2, so as to replace one of the FPC 6 to be transported with another FPC 6 to be transported in the same workstation, thereby avoiding other workstations from being in an empty waiting state when the FPC 6 is tested, and avoiding the test station from being in an empty state for a long time after the FPC 6 is moved out of the test station after the test is completed, thereby reducing unnecessary waiting time in the entire test process, and ultimately improving the overall test efficiency and test capacity of the FPC 6, which is beneficial to improving the market competitiveness of the manufacturer.

[0047] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0048] Further, as a specific implementation in some embodiments of the present invention, Figure 1 and Figure 2 As shown, the first linear moving component 1 and the second linear moving component 2 are located at the same height. In this way, the first linear moving component 1 and the second linear moving component 2 are arranged parallel to each other on the horizontal plane. Therefore, the FPC test material transport device 100 is very suitable for use in scenarios where the width space is sufficient but the height is insufficient. In addition, adopting this structure can lower the center of gravity of the FPC test material transport device 100, which is conducive to ensuring the stability of the FPC test material transport device 100 and the stability of the material transport process.

[0049] Further, as a specific implementation in some embodiments of the present invention, Figure 1 and Figure 2As shown, in order to simplify the structure of the FPC test material transport device 100, the first linear motion component 1 and the second linear motion component 2 have the same structure. Of course, in fact, the two can also adopt different structures as long as the linear motion function of the support can be realized. It should be noted that for the convenience of description, the specific structure of the second linear motion component 2 is omitted below, and the structure of the first linear motion component 1 is used as an example for explanation.

[0050] Specifically in this embodiment, Figure 1 and Figure 2 As shown, the first linear motion component 1 includes a first driving component (not shown) and a first linear guide 12 arranged horizontally (specifically, it can be the extension direction of the first linear motion component 1), and the first lifting component 3 includes a mounting seat 31, a second driving component (not shown) and a second linear guide 33 arranged vertically, wherein the mounting seat 31 of the first lifting component 3 is slidably arranged on the first linear guide 12 of the first linear motion component 1, and the mounting seat 31 is arranged on the first driving component of the first linear motion component 1, so as to be driven by the first driving component to slide in the horizontal direction. In short, under the drive of the first driving component of the first linear motion component 1, the mounting seat 31 of the first lifting component 3 can slide back and forth along the first linear guide 12, thereby carrying the support member installed on the first lifting component 3 to slide back and forth horizontally relative to the first linear guide 12.

[0051] For example Figure 1 and Figure 2 As shown, one end of a support member is slidably disposed on the second linear guide rail 33 of the first lifting assembly 3, and is disposed on the second driving assembly to be driven by the second driving assembly to slide vertically. In this way, the one support member can move up and down relative to the first lifting assembly 3, so as to adjust the height difference between the one support member and the other support member, thereby avoiding interference and collision between the two support members when they move up and down alternately.

[0052] It should be noted that, Figure 1 and Figure 2 As shown, to ensure overall stability, the first linear motion assembly 1 further includes a support column 13, wherein the support column 13 is mainly used to support other components in the first linear motion assembly 1, as well as the first lifting assembly 3 and a support member.

[0053] Further, as a specific implementation in some embodiments of the present invention, Figure 1 and Figure 2As shown, the first driving assembly (not shown) of the first linear motion assembly 1 includes a first servo motor (not shown) and a belt transmission structure 11 driven by the first servo motor and arranged transversely, wherein the belt transmission structure 11 is mainly used to drive the mounting seat 31 of the first lifting assembly 3 to slide along the horizontal direction (specifically, the first linear motion assembly 1, such as the extension direction of the first linear guide rail 12). Of course, in fact, other suitable structures such as a ball screw structure can also be used in the first driving assembly to replace the belt transmission structure 11.

[0054] Further, as a specific implementation in some embodiments of the present invention, Figure 1 and Figure 2 As shown, the second driving assembly (not shown) of the first lifting assembly 3 includes a second servo motor (not shown) and a vertically arranged ball screw (not shown) driven by the second servo motor, wherein the ball screw is mainly used to drive the support member to slide vertically. Of course, in fact, other suitable structures such as a belt drive structure 11 can also be used in the second driving assembly to replace the ball screw.

[0055] Further, as a specific implementation in some embodiments of the present invention, Figure 1 and Figure 2 As shown, in order to simplify the overall structure of the FPC testing material transporting device 100, the first lifting assembly 3 and the second lifting assembly 4 are located at the same height, which is also conducive to better ensuring that the initial positions of the two supporting members are located at the same height.

[0056] Furthermore, as a specific implementation method in some embodiments of the present invention, when the two support members move up and down alternately, in order to ensure that the two support members do not collide and to minimize the up and down movement distance of the support members, the height difference between the two support members is in the range of 70mm to 90mm.

[0057] Based on the above-mentioned FPC test material transport device 100, an embodiment of the present invention further provides a test system, which includes a control device and the above-mentioned FPC test material transport device 100, wherein the FPC test material transport device 100 is controlled by the control device so that the two support members can achieve up and down staggered movement during the lateral material transport process (specifically, the extension direction of the first linear motion component 1 or the second linear motion component 2), so that the FPC 6 to be tested can replace the tested FPC 6 in the test station. It can be understood that the test system is a test system for FPC 6, which is mainly used to perform electrical performance tests on FPC 6.

[0058] Further, as a specific implementation in some embodiments of the present invention, the test system further includes a loading manipulator (not shown) and a unloading manipulator (not shown), wherein the loading manipulator and the unloading manipulator are arranged opposite to each other and are located outside the FPC test material transport device 100. Specifically, in order to simplify the material transport process and reasonably arrange the overall structure, the loading manipulator can be located outside the first linear motion component 1, and the unloading manipulator can be located outside the second linear motion component 2, that is, the loading manipulator and the unloading manipulator are respectively located on opposite sides of the support. Of course, in fact, the two can also be located on the same side of the support.

[0059] Specifically in this embodiment, the loading station and the unloading station are the same station, which is conducive to further improving the test efficiency and the test capacity.

[0060] In summary, compared with the prior art, the test system has at least the following beneficial effects: by adopting the above-mentioned FPC test material transport device 100, the test system not only improves the test efficiency and test capacity, but also simplifies the overall structure of the test system to a certain extent.

[0061] Based on the above test system, the test method of the test system of the present invention is the test method of the test system using the above FPC test material transporting device 100. For the convenience of description, the following description is made by taking the support member provided on the first linear motion component 1 as an example for first loading.

[0062] In this embodiment, the testing method of the testing system of the present invention includes the following steps:

[0063] S100: Loading an FPC 6 to be tested onto a support member in a loading station.

[0064] It should be noted that the two support members can both be at the positions corresponding to the loading station as the initial positions. In this step S100, in the loading station, the support member corresponding to the first linear motion component 1 (for the convenience of explanation, the support member is temporarily referred to as the first support member 5-1) can be loaded by the loading robot to load the first FPC 6 onto the support member.

[0065] S200: transport an FPC 6 to be tested to the test station for testing, then load another FPC 6 to be tested onto another support member (for convenience of explanation, the support member is temporarily referred to as the second support member 5-2) in the loading station, and transport another FPC 6 to be tested to the test station.

[0066] In step S200, the first support 5-1 is first transported to the test station, and the second support 5-2 is then transported to the test station. The first support 5-1 transports the first FPC 6 to the test station after loading, and tests it in the test station. During the period from when the first support 5-1 leaves the loading station to when the FPC 6 to be tested on the first support 5-1 is tested, the test system can load the second FPC 6 onto the second support 5-2 in the loading station through the loading manipulator, and transport the second FPC 6 to the test station, so as to avoid the loading station being in an empty state when the FPC 6 in the test station is tested, and facilitate the replenishment of the FPC 6 in a very short time after the FPC 6 in the test station is tested. In short, the interval between when the previous FPC 6 is tested and when the next FPC 6 is tested is greatly reduced. It should be noted that, in the case where the second support 5-2 is transported to the test station before the first support 5-1, step S200 is also applicable, and it is only necessary to replace the first support 5-1 with the second support 5-2, and the second support 5-2 with the first support 5-1. That is, the first support 5-1 and the second support 5-2 are in a two-way replacement relationship, not a one-way replacement.

[0067] S300: In the test station, two support members are alternately displaced up and down, so that the tested FPC 6 is transported to the unloading station through the corresponding support members, and the FPC 6 to be tested replaces the tested FPC 6 to continue testing.

[0068] In step S300, similarly, the first support 5-1 is first transported to the test station, and the second support 5-2 is then transported to the test station. It should be noted that before the second support 5-2 enters the position corresponding to the test station, it is necessary to complete the positional relationship between the second support 5-2 and the first support 5-1 in an up-and-down arrangement, so as to avoid interference between the two supports. In addition, after the first FPC 6 in the first support 5-1 is tested, the first support 5-1 is gradually moved out of the test station to be transported to the unloading station (that is, transported back to the loading station) under the linkage of the first linear moving component 1 and / or the first lifting component 3, and at the same time, the second FPC 6 on the second support 5-2 is gradually moved to the test station, so as to complete the up-and-down displacement alternation between the two supports to continue the test.

[0069] It should also be noted that the specific movement scheme between the two supports needs to be determined according to the actual situation, and will not be listed here one by one. In addition, when the second support 5-2 is transported to the test station before the first support 5-1, step S300 is also applicable. Similarly, it is only necessary to replace the first support 5-1 with the second support 5-2, and the second support 5-2 with the first support 5-1. That is, the first support 5-1 and the second support 5-2 are in a two-way replacement relationship, not a one-way replacement.

[0070] S400: another FPC 6 to be tested is loaded in the loading station onto the corresponding support member that has completed unloading, and transported to the testing station. Then, the FPC 6 that has been tested is replaced in the testing station to continue testing. Meanwhile, the FPC 6 that has been tested is transported to the unloading station through the corresponding support member.

[0071] In step S400, similarly, the first support 5-1 is first transported to the test station, and the second support 5-2 is transported to the test station later as an example. When the first FPC 6 on the first support 5-1 completes the test and returns from the test station to the loading station, the FPC 6 that has completed the test is unloaded by the unloading robot, and when the second FPC 6 on the second support 5-2 is tested in the test station, the third FPC 6 can be continuously loaded onto the first support 5-1 by the loading robot and transported to the test station to replace the second FPC 6 that has completed the test on the second support 5-2 in the test station, and the replacement is specifically performed by the upper and lower staggered alternating method in step S300. At the same time, the second support 5-2 returns to the loading station (also the unloading station in this embodiment) with the second FPC 6 that has completed the test.

[0072] S500: Repeat the previous step, specifically repeat step S400, so as to alternately switch the two support members in the test station until the target test sample is completed.

[0073] In summary, compared with the prior art, the testing method of the testing system has at least the following beneficial effects: the overall process of the testing method of the above-mentioned testing system is simple and reliable, the testing efficiency is high, and it is conducive to improving the testing capacity.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
