[0036] The technical solutions of the present utility model will be further illustrated below in conjunction with the drawings and through specific embodiments.

[0037] The present embodiment provides a front and back surface auxiliary testing device, which can realize automatic testing, has high automation degree and reliability, and can also reduce the risk of missed detection.

[0038] The front and back surface auxiliary testing device in the present embodiment can be applied to a front and back surface testing equipment, wherein the front and back surface testing equipment further comprises a tester, which can be used for performance testing of a to-be-tested product. The tester has a test terminal, which can be inserted into the to-be-tested product to form a test circuit with the to-be-tested product. The front and back surface auxiliary testing device is used for assisting the tester in testing the to-be-tested product, so as to reduce the testing difficulty of the to-be-tested product and improve the testing reliability.

[0039] Exemplarily, the to-be-tested product can be a connector interface or a connector female seat, and the connector head port can be a component that has been installed on an electronic device or a component that has not been installed on an electronic device, which is not limited in the present embodiment. The test terminal is compatible with the model of the connector interface.

[0040] As shown in Figure 1 and Figure 2 , the front and back surface auxiliary testing device comprises a first positioning mechanism 100, a second positioning mechanism, a turnover mechanism 200 and a translation driving member 300. The first positioning mechanism 100 is used for positioning the to-be-tested product to prevent the to-be-tested product from moving during testing. The second positioning mechanism is oppositely arranged with the first positioning mechanism 100. For example, the second positioning mechanism is oppositely arranged with the first positioning mechanism 100 in the second direction Y. The second positioning mechanism is used for fixing the test terminal, so that the test terminal can move when the second positioning mechanism moves.

[0041] The flipping mechanism 200 in the embodiment is connected to the second positioning mechanism and is used to drive the second positioning mechanism to rotate, so that the second positioning mechanism drives the test terminal to flip around its own axis to achieve the purpose of turning over. The translation driving member 300 in the embodiment is connected to the first positioning mechanism 100 and / or the second positioning mechanism and is used to drive the first positioning mechanism 100 and / or the second positioning mechanism to move, so as to adjust the distance between the first positioning mechanism 100 and the second positioning mechanism. When the second positioning mechanism moves relative to the first positioning mechanism 100, the test terminal can be inserted into the product to be tested.

[0042] In an implementation, the translation driving member 300 is connected to the second positioning mechanism and is used to drive the second positioning mechanism to move towards or away from the first positioning mechanism 100, so that the test terminal moves towards or away from the product to be tested to be inserted into or pulled out of the product to be tested. For example, the movement of the second positioning mechanism towards the first positioning mechanism 100 can make the test terminal inserted into the product to be tested to facilitate the test of the product to be tested.

[0043] When the front and back surface auxiliary test device provided by the embodiment is used, the product to be tested is first fixed on the first positioning mechanism 100, and the test terminal is fixed on the second positioning mechanism. It should be noted that after the product to be tested and the test terminal are positioned, the product to be tested located on the first positioning mechanism 100 and the test terminal located on the second positioning mechanism are coaxially arranged, and the outer circumferential surface of the test terminal is parallel to the hole wall of the jack of the product to be tested one by one, so that the test terminal can be inserted into the jack of the product to be tested. Then, the tester is started, and the translation driving member 300 is controlled to move the second positioning mechanism towards the first positioning mechanism 100 until the test terminal is inserted into the jack of the product to be tested. The tester performs front surface test of the product to be tested. After the test is completed, the translation driving member 300 drives the second positioning mechanism to move away from the first positioning mechanism 100, so that the test terminal moves out of the jack of the product to be tested.

[0044] Next, control the flipping mechanism 200 to actuate, driving the second positioning mechanism to rotate 180 degrees. At this time, the test terminal to be tested rotates 180 degrees following the second positioning mechanism, achieving the flipping of the test terminal. After the flipping is completed, the translation driving member 300 drives the second positioning mechanism to move towards the first positioning mechanism

[100] again until the test terminal is inserted into the jack of the product to be tested. The tester conducts the reverse test on the product to be tested. After the test is completed, the translation driving member 300 drives the second positioning mechanism to move away from the first positioning mechanism

[100] to move the test terminal out of the jack of the product to be tested. The switching test of the front and back sides of the product to be tested is achieved. Only when the front test and the reverse test of each product to be tested are qualified can it be determined that the product to be tested is qualified.

[0045] The front and back side auxiliary testing device provided in this embodiment realizes the fixation of the product to be tested and the test terminal by setting the first positioning mechanism

[100] and the second positioning mechanism. The flipping mechanism

[200] can drive the second positioning mechanism to rotate, and thus can achieve the flipping of the test terminal to be tested, facilitating the front test and the reverse test of the product to be tested without manual flipping. The setting of the translation driving member

[300] enables the distance between the first positioning mechanism

[100] and the second positioning mechanism to be automatically adjusted. When the distance between the second positioning mechanism and the first positioning mechanism

[100] gradually decreases under the drive of the translation driving member

[300] , the test terminal on the second positioning mechanism can be inserted into the product to be tested, achieving the automatic insertion of the product to be tested and the test terminal, realizing the automatic testing of the product to be tested, having a high degree of automation and reliability, and also being able to reduce the risk of missed inspection.

[0046] In addition, the front and back side auxiliary testing device provided in this embodiment has fewer steps that require manual operation during the testing process, enabling an operator to operate multiple front and back side testing devices simultaneously, thereby improving the testing efficiency.

[0047] Exemplarily, the specific structure of the first positioning mechanism

[100] can have various forms. For example, as Figure 1 shown, the first positioning mechanism

[100] includes a first positioning table

[110] and a first clamping and fixing component. The first positioning table

[110] is used to support the product to be tested or an electronic device including the product to be tested. The first clamping and fixing component can clamp and fix the product to be tested alone, or can cooperate with the first positioning table

[110] to clamp the product to be tested. This embodiment does not limit this. For example, the first clamping and fixing component includes a cover plate and a locking member. Both the cover plate and the first positioning table

[110] have grooves. The groove on the cover plate and the groove on the first positioning table

[110] cooperate with each other to form a fixing cavity that matches the product to be tested. The locking member is used to lock the cover plate on the first positioning table

[110] to prevent the cover plate from moving relative to the first positioning table

[110] . The locking member includes but is not limited to bolts. The cover plate and the first positioning table

[110] are connected by bolts.

[0048] In some optional embodiments, the first positioning mechanism 100 further comprises a second positioning table 120, which is arranged at one side of the first positioning table 110 and is used to support the electronic device including the product to be tested, so as to reduce the risk of movement of the product to be tested under the pulling of the electronic product.

[0049] Optionally, the second positioning mechanism can have various specific forms. In some optional embodiments, the second positioning mechanism has a through hole, and an inner wall of the through hole is provided with an elastic pad including but not limited to silica gel and rubber. The test terminal is not inserted into the product to be tested, but is fixed in the through hole and elastically abuts against the elastic pad. The elastic pad can prevent the test terminal from moving relative to the second positioning mechanism. It should be noted that the adapter line connected to the test terminal can also be fixed in the through hole, so as to further reduce the movement of the test terminal. In some other optional embodiments, the second positioning mechanism can include a positioning body and a plurality of clamping blocks. The positioning body has a hollow cavity, and each clamping block is connected to an inner wall of the hollow cavity of the positioning body by a spring or other elastic member. Under the elastic force of the spring, the plurality of clamping blocks cooperatively clamp the test terminal, so as to facilitate replacement of the test terminal.

[0050] The structure of the turnover mechanism 200 can have various forms, as long as it can drive the second positioning mechanism to rotate. In one implementation manner, as shown in Figure 1 the turnover mechanism 200 includes a turnover driving member 210 and a transmission assembly (not shown in the figure). The output end of the turnover driving member 210 is connected to the transmission assembly, the transmission assembly is connected to the second positioning mechanism, and the turnover driving member 210 drives the second positioning mechanism to rotate through the transmission assembly. By arranging the transmission assembly, the arrangement position of the turnover driving member 210 can be more flexible, so as not to affect the arrangement of the test terminal and the adapter line connected to the test terminal.

[0051] Of course, it can be understood that the turnover mechanism 200 can also not include the transmission assembly, but only include the turnover driving member 210, which is directly connected to the second positioning mechanism and drives the second positioning mechanism to rotate. This embodiment does not limit this.

[0052] Exemplarily, the turnover driving member 210 can be a motor, and can also be other components capable of outputting torque. This embodiment does not limit this.

[0053] In order to reduce the complexity of the turnover mechanism 200, in some optional embodiments, the transmission assembly comprises a driving gear and a driven gear connected to the driving gear. Specifically, the driving gear and the driven gear are both external gears, and the driving gear is in meshing connection with the driven gear to realize the transmission connection therebetween. The output end of the turnover driving member 210 is coaxially connected with the driving gear and is used to drive the driving gear to rotate. For example, the turnover driving member 210 has an output shaft, the driving gear is fixedly sleeved on the output shaft, and when the output shaft rotates, the driving gear can be driven to rotate, and in turn the driven gear is driven to rotate. The second positioning mechanism is coaxially connected with the driven gear, so that when the driven gear rotates, the second positioning mechanism can be driven to rotate. In some optional embodiments, the second positioning mechanism has the same axis as the test terminal when the driven gear rotates, so that when the second positioning mechanism rotates, the test terminal can rotate.

[0054] Further, referring to Figure 1 , the turnover mechanism 200 further comprises a turnover support plate 220. The turnover support plate 220 is connected to the output end of the translation driving member 300, the turnover driving member 210 is arranged on the turnover support plate 220, the turnover support plate 220 is provided with a first through hole 221, and the second positioning mechanism is provided with a second through hole communicated with the first through hole 221. The test terminal is connected with a conversion line, and the conversion line is arranged through the first through hole 221 and the second through hole.

[0055] Since the test terminal needs to be connected to the tester through the conversion line for signal conversion, the turnover support plate 220 with the first through hole 221 and the second positioning mechanism with the second through hole can avoid unstable signal transmission caused by the conversion line bending while meeting the turnover of the test terminal, thereby ensuring the stability of signal transmission and further ensuring the accuracy of the test.

[0056] In order to improve the strength of the connection between the turnover support plate 220 and the output end of the translation driving member 300, as Figure 1 indicated, the turnover mechanism 200 further comprises a reinforcing plate 230. The second positioning mechanism is arranged on one side of the turnover support plate 220, and the reinforcing plate 230 is arranged on the other side of the turnover support plate 220, so that the reinforcing plate 230 does not interfere with the rotation of the second positioning mechanism. Moreover, the reinforcing plate 230 is connected between the turnover support plate 220 and the output end of the translation driving member 300, so as to reduce the risk of connection failure between the turnover support plate 220 and the output end of the translation driving member 300.

[0057] In order to ensure that the test terminal can be turned over by 180 degrees each time, optionally, as Figure 1 indicated, the front-back surface auxiliary test device further comprises a limiting structure 410. The limiting structure 410 is used to limit the upper limit of the rotation angle of the second positioning mechanism, so as to prevent the rotation angle of the second positioning mechanism from being greater than 180 degrees, and in turn the test terminal can be turned over.

[0058] In one embodiment, please continue Figure 1 The front-back auxiliary testing device further comprises a working platform 500. The limiting structure 410, the first positioning mechanism 100, the overturning mechanism 200 and the translation driving member 300 are all arranged on the working platform 500. The second positioning mechanism has a first testing state and a second testing state, and the second positioning mechanism is provided with a limiting cooperation structure 420. When the second positioning mechanism is in the first testing state, the front testing of the product to be tested can be realized, and the limiting cooperation structure 420 is located on the side of the second positioning mechanism away from the limiting structure 410. For example, the limiting cooperation structure 420 is located directly above the second positioning mechanism, and the limiting structure 410 is located directly below the second positioning mechanism. When the second positioning mechanism is in the second testing state, the limiting cooperation structure 420 abuts against the limiting structure 410, and the second positioning mechanism has been rotated into position, at this time, the testing terminal can be inserted into the product to be tested when moving in the second direction Y, so as to realize the back testing of the product to be tested. For example, the limiting structure 410 and the limiting cooperation structure 420 can both be blocks or pieces, and the present embodiment does not limit this.

[0059] By arranging the limiting structure 410 and the limiting cooperation structure 420, it can be ensured that the second positioning mechanism can be rotated by at most 180 degrees from the first testing state to the second testing state under the driving of the overturning driving member 210, so that the testing terminal is just in the state of being able to be inserted into the product to be tested after overturning, which has high foolproofness and ensures the automatic testing process.

[0060] It can be understood that the upper part of the second positioning mechanism can also be provided with a limiting member for limiting. For example, the limiting member is arranged on the overturning support plate 220, and when the second positioning mechanism is in the first testing state, the limiting cooperation structure 420 can abut against the limiting member, so as to ensure that the second positioning mechanism is just in the second testing state, thereby ensuring that the testing terminal can be inserted into the product to be tested.

[0061] In some optional embodiments, as Figure 2As shown, the first positioning mechanism 100 is adjustably arranged on the workbench 500 in the first direction X to facilitate fixing the product to be tested on the first positioning mechanism 100. Specifically, when positioning the product to be tested, the first positioning mechanism 100 can be moved in the first direction X so that the first positioning mechanism 100 is no longer arranged opposite to the second positioning mechanism in the second direction Y. At this time, the first positioning mechanism 100 has a larger operation space on the side facing the second positioning mechanism, facilitating manual fixing of the product to be tested on the first positioning mechanism 100. The first direction X is perpendicular to the direction in which the second positioning mechanism approaches or moves away from the first positioning mechanism 100, i.e., the first direction X is perpendicular to the second direction Y. In this embodiment, the workbench 500 can be provided with a sliding groove, and the first positioning mechanism 100 is slidingly arranged in the sliding groove. The sliding groove extends in the first direction X. When the first positioning mechanism 100 abuts against one groove wall of the sliding groove in the first direction X, it is just positioned opposite to the second positioning mechanism, i.e., positioned at a position where the test terminal can be inserted into the product to be tested, thereby achieving positioning of the first positioning mechanism 100 on the workbench 500. The first positioning mechanism 100 can be connected to the workbench 500 by bolts or other fixing members. When the first positioning mechanism 100 needs to be moved, the bolts are unscrewed so that the first positioning mechanism 100 can move relative to the workbench 500.

[0062] To avoid the test terminal from being excessively inserted into the product to be tested, in this embodiment, the front-back surface auxiliary testing device further comprises a stopper. The stopper is arranged on the first positioning mechanism 100 or the workbench 500. The stopper is used to abut against the output end of the second positioning mechanism or the translation driving member 300 to limit the lower limit of the distance between the second positioning mechanism and the first positioning mechanism 100, thereby limiting the maximum length of the test terminal inserted into the product to be tested. The lower limit of the distance between the first positioning mechanism 100 and the second positioning mechanism satisfies that the test terminal and the product to be tested are inserted into place without being excessively inserted or not inserted into place, thereby improving the accuracy of testing the product to be tested. Exemplarily, the stopper includes but is not limited to a stopper block.

[0063] This embodiment further provides a front-back surface testing device comprising the above-mentioned front-back surface auxiliary testing device. The front-back surface testing device further comprises a tester having a test terminal arranged on the second positioning mechanism.

[0064] The front-back surface testing device provided by this embodiment can realize automatic testing, has a high degree of automation and reliability, and can also reduce the risk of missed detection.

[0065] It should be noted that the above only the preferred embodiments of the present application and the use of technical principles. Those skilled in the art will understand that the present application is not limited to the specific embodiments described herein, those skilled in the art can make various obvious changes, re-adjustment and replacement without departing from the scope of the present application.
