Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic product testing, and in particular to a conduction test system. BACKGROUND

[0002] With the development of science and technology, electronic products are constantly iterated and updated, and their manufacturing processes are increasingly complex, structural designs are increasingly precise, and functions are increasingly comprehensive. In view of this, it is crucial to ensure the performance and quality of electronic products in the production process of electronic products. Generally, the performance parameters of electronic products need to be tested before they are shipped. Generally, the connector of the product to be tested is accurately pressed into a detection special electrical measuring cavity, so that the connector is in conduction with the test equipment, the test equipment outputs a signal to be tested for conduction test, so that the information fed back by the product to be tested can be received to confirm whether the product to be tested has any defects.

[0003] However, the connector is usually soft, so the connector is easily bent multiple times during transportation, making the shape of the connector extremely irregular. Even before being tested, the connector can have a large deformation. If the relative position of the product body and the connector is not effectively fixed during the transfer process of the product to be tested, there will be relative displacement between the connector and the product body. The above factors all cause the connector to be unable to be accurately pressed into the electrical measuring cavity, thereby affecting the pressure conduction and test efficiency. At the same time, since the loading and unloading operation, the shaping operation and the conduction test operation all need to be completed on different platforms, if they cannot be well connected, it will also cause the conduction test to be low in efficiency. SUMMARY

[0004] Therefore, it is necessary to provide a conduction test system with high automation and high test accuracy to solve the problems of low test accuracy and low automation of the existing conduction test system, which leads to low test efficiency.

[0005] According to one aspect of the present application, a conduction test system is provided, comprising: a transmission module, a shaping platform, a carrying mechanism and an electrical measuring platform arranged in sequence along a transmission direction on the transmission module;

[0006] The shaping platform is used to fix a to-be-tested part of a product to be tested and a product body of the product to be tested, and is used to shape the to-be-tested part;

[0007] The electrical measuring platform has an electrical measuring cavity with variable size in a pressing direction, and is used to fix the to-be-tested part in the electrical measuring cavity to enable conduction test on the to-be-tested part;

[0008] The transport mechanism is used to transfer the product to be tested from the shaping platform to the electrical testing platform, and maintain the relative position of the part to be tested and the main body of the product during the transfer process, so that the part to be tested can be pressed into the electrical testing cavity.

[0009] In one embodiment, the continuity testing system has a shaping station, a photographing station, and an electrical testing station arranged sequentially at intervals along the transmission direction. The photographing station is equipped with a camera, which is used to photograph and locate the position of the product under test relative to the electrical testing platform, so that the conveying mechanism can accurately press the part under test into the electrical testing cavity.

[0010] In one embodiment, the transmission module includes a first linear module, a second linear module, and a third linear module arranged sequentially at intervals along the transmission direction. The shaping platform is movably mounted on the first linear module to be able to travel back and forth between the shaping station and the photographing station. The conveying mechanism is movably coupled to the second linear module to be able to travel back and forth between the photographing station and the electrical testing station. The electrical testing platform is movably mounted on the third linear module to adjust the relative position of the electrical testing platform and the product under test when the conveying mechanism transfers the product under test to the electrical testing station.

[0011] In one embodiment, the transmission module further includes a lifting linear module, which is movably mounted on the second linear module and can move relative to the second linear module along the transmission direction. The conveying mechanism is movably mounted on the lifting linear module to be coupled to the second linear module through the lifting linear module. The conveying mechanism can move up and down relative to the lifting linear module in a controllable manner.

[0012] In one embodiment, the shaping platform includes a first support plate and a shaping mechanism. The shaping mechanism is disposed on the first support plate, and the first support plate is used to support the product body. The shaping mechanism has a pressure head assembly and at least two push head assemblies. Each push head assembly has a first sliding surface. The pressure head assembly has at least two second sliding surfaces that are parallel to a corresponding first sliding surface and are arranged opposite to each other in a horizontal direction. The distance between the two second sliding surfaces gradually increases in the top-to-bottom direction.

[0013] The at least two pusher assemblies can be controllably moved closer or further apart along the horizontal direction, so that the first sliding surface is in contact with the second sliding surface and moves relative to the second sliding surface to clamp or release the test part of the product under test, and drive the pressure head assembly to move up and down to shape the test part of the product under test.

[0014] In one embodiment, each of the pusher assembly includes a pusher and a first wedge block connected to each other, and the pressure head assembly includes a pressure block and a second wedge block connected to each other, the first wedge block being engaged with the pressure block through the second wedge block, the first sliding surface being disposed on the first wedge block, and the second sliding surface being disposed on the second wedge block;

[0015] The shaping mechanism further includes a support base with a mounting position. The push head and the pressure block are partially disposed within the mounting position. The push head has a clamping part for clamping the part to be tested, which is exposed outside the mounting position. The side wall of the support base also has a through hole communicating with the mounting position, and the pressure block is partially exposed outside the through hole. The clamping parts of the two push heads arranged opposite each other are located on opposite sides of the pressure head in the horizontal direction. The clamping parts, the pressure block, the first support plate, and the support base together form a shaping gap outside the support base for accommodating the part to be tested.

[0016] In one embodiment, the conveying mechanism includes:

[0017] A bracket is movably connected to the transmission module;

[0018] A gripper assembly, coupled to the bracket, the gripper assembly having at least two opposing grippers, the two opposing grippers being controllably brought closer to each other to clamp the part to be tested;

[0019] An adsorption component is movably mounted on the support and is controllably movable up and down relative to the gripper assembly to adsorb the product body before the gripper assembly clamps the part to be tested.

[0020] In one embodiment, the conveying mechanism further includes a rotating component, the gripper assembly being coupled to the support via the rotating component, the rotating component being capable of driving the gripper assembly to rotate about an axis perpendicular to the conveying direction.

[0021] In one embodiment, the electrical testing platform includes:

[0022] A base that is movably mounted on the transmission module;

[0023] The second support plate is movably mounted on the base and can move up and down relative to the base in a controllable manner. The second support plate is used to support the main body of the product.

[0024] The electrical testing mechanism includes a fixed block, a pre-pressing block, and a final pressing block. The fixed block is fixedly mounted on the base. The pre-pressing block is movably coupled to the fixed block and can reciprocate relative to the fixed block along the pressing direction. One side surface of the pre-pressing block and one side surface of the fixed block are arranged opposite to each other and together form the electrical testing cavity. The final pressing block is movably mounted on the second support plate and can reciprocate relative to the second support plate along the pressing direction.

[0025] In one embodiment, the electrical testing mechanism further includes a trajectory guide block movably coupled to the pre-pressure block, and the trajectory guide block has a guide surface. The pre-pressure block is also controllably movable up and down relative to the fixed block and the trajectory guide block, so that the guide surface can guide the pre-pressure block to reciprocate along the pressing direction while moving up and down.

[0026] In one embodiment, the pre-compression block is provided with a sliding body, which is movably connected to the guide surface. The guide surface includes a first guide surface, a second guide surface, and a third guide surface connected in sequence. In the pressing direction, the distance between the third guide surface and the extended surface of the pre-compression block near the fixed block is greater than the distance between the first guide surface and the extended surface of the pre-compression block near the fixed block.

[0027] When the pre-compression block moves up and down relative to the trajectory guide block, it can drive the sliding body to move on the guide surface, thereby driving the pre-compression block to move along the pressing direction at the same time.

[0028] In one embodiment, the pre-pressure block has a pre-pressure needle for holding the part to be tested, and the final pressure block has a relief groove. When the final pressure block approaches the electrical testing cavity and holds the part to be tested, the portion of the pre-pressure needle that holds the part to be tested is received in the relief groove.

[0029] The above-mentioned continuity testing system has the following technical advantages:

[0030] By setting up a shaping platform in the continuity testing system and placing it upstream of the electrical testing platform, the part under test (DUT) of the product under test (e.g., a connector of an electronic product) is shaped on the shaping platform before being transported to the electrical testing platform for continuity testing. This allows the shape of the DUT to be shaped within the theoretical range. Furthermore, during the transport of the product body and the DUT to the electrical testing platform, the transport mechanism maintains the relative position of the DUT and the product body. This ensures that the shape of the DUT remains in its shaped state when the product under test is transported to the electrical testing platform for continuity testing, and that the relative position of the DUT and the product body remains fixed. This allows the DUT to be precisely pressed into the electrical testing cavity of the electrical testing platform, improving pressing accuracy, ensuring the crimped continuity of the DUT, and effectively guaranteeing testing accuracy. Furthermore, the aforementioned continuity testing system is a fully automated production line, which enables the shaping, transfer, and continuity testing processes to be completed automatically. The cycle time of each process is optimized, resulting in a high degree of automation, reduced labor costs, and a significant improvement in testing efficiency. Attached Figure Description

[0046] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0047] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "level," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0049] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the liquid level of the first feature is higher than that of the second feature.

[0051] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0052] One embodiment of the present invention provides a continuity testing system. This continuity testing system is used to press the part under test of a product under test into a dedicated electrical testing cavity for conducting continuity testing on the product under test. This allows for the detection of defects in the product under test before it leaves the factory. Furthermore, the continuity testing system is used to reshape the connector of the part under test before conducting continuity testing to eliminate irregular deformations, thereby ensuring that the part under test can be accurately pressed into the electrical testing cavity for continuity testing, thus improving testing accuracy and efficiency.

[0053] The following description uses an electronic product as the product under test (DUT) and its connector as the part under test (DUT) as an example to illustrate the structure of the continuity testing system in this application. This embodiment is only used as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the continuity testing system of this application can be used to perform continuity testing on the DUT of any electronic product, and is not limited here.

[0054] The following combination Figures 1 to 12 This application introduces a preferred embodiment of the continuity testing system provided in this application.

[0055] like Figure 1 and Figure 2 As shown, a continuity testing system 10 is used to perform continuity testing on electronic products before they leave the factory. The continuity testing system 10 includes a transmission module 100 and a transmission path along a transmission direction (e.g., ...). Figure 1The shaping platform 200, the conveying mechanism 300, and the electrical testing platform 400 are sequentially arranged on the transmission module 100 (in the direction indicated by the middle arrow). The shaping platform 200 is used to fix the part under test (in this embodiment, the part under test is a connector of an electronic product, hereinafter referred to as a connector) of a product under test to the main body of the product under test, and is used to shape the connector; combined with... Figure 8 As shown, the electrical testing platform 400 has a variable-sized electrical testing cavity 401. The conveying mechanism 300 is used to transfer the product to be tested from the shaping platform 200 to the electrical testing platform 400, and maintain the relative position of the connector and the product body during the transfer process so that the connector can be pressed into the electrical testing cavity 401. The electrical testing platform 400 is used to fix and limit the connector in the electrical testing cavity 401 so that the connector can fully contact the conductive part (not shown in the figure, such as a blade needle) provided on the side wall of the electrical testing cavity, so that the connector can be tested for continuity.

[0056] Preferably, the continuity testing system 10 also includes a camera 500, and the continuity testing system 10 has a shaping station 11, a photographing station 12, and an electrical testing station 13 arranged sequentially at intervals along the transmission direction. The camera 500 is located at the photographing station 12. After the connector of the product under test is shaped by the shaping platform 200, the transmission module 100 can transfer the shaping platform 200 carrying the product under test from the shaping station 11 to the photographing station 12 for the camera 500 to take a picture, so as to obtain the relative position of the product under test and the electrical testing platform 400. The XY coordinate adjustment parameters are then transferred from the shaping platform 200 to the transport mechanism 300, and the product to be tested is transferred from the photography station 12 to the electrical testing station 13. Finally, the product to be tested is transferred to the top of the electrical testing platform 400. The system adjusts the position of the electrical testing platform 400 on the third linear module 130 according to the XY coordinate adjustment parameters obtained by the camera 500, so that the transport mechanism 300 can accurately press the connector into the electrical testing cavity 401 of the electrical testing platform 400.

[0057] In some embodiments, the transmission module 100 includes a first linear module 110, a second linear module 120, and a third linear module 130 arranged sequentially at intervals along the transmission direction. The first linear module 110 extends from the shaping station 11 to the imaging station 12, the second linear module 120 extends from the imaging station 12 to the electrical testing station 13, and the third linear module 130 extends from the electrical testing station 13 to the outlet of the conduction testing system 10. The shaping platform 200 is movably mounted on the first linear module 110 and can controllably travel back and forth between the shaping station 11 and the imaging station 12 along the extension direction of the first linear module 110. The conveying mechanism 300 is movably coupled to the second linear module 120 and can controllably travel back and forth between the imaging station 12 and the electrical testing station 13 along the extension direction of the second linear module 120. The electrical testing platform 400 is movably mounted on the third linear module 130 and can controllably travel back and forth between the imaging station 12 and the electrical testing station 13 along the extension direction of the third linear module 130. The device travels back and forth between the electrical testing station 13 and the exit of the continuity testing system 10. This allows the relative position of the electrical testing platform 400 and the product under test to be adjusted when the transport mechanism 300 transfers the product under test to the electrical testing station 13. This enables the transport mechanism 300 to accurately press the connector into the electrical testing cavity 401 of the electrical testing platform 400. Simultaneously, the electrical testing platform 400 carrying the product under test can be transferred from the electrical testing station 13 to the exit of the continuity testing system 10 after the continuity test is completed. The extension directions of the first linear module 110, the second linear module 120, and the third linear module 130 together form the transmission direction of the continuity testing system 10.

[0058] In a preferred embodiment, the transmission module 100 further includes a lifting linear module 140, which is movably mounted on the second linear module 120. The lifting linear module 140 can controllably move back and forth between the photographing station 12 and the electrical testing station 13 along the extension direction of the second linear module 120. A conveying mechanism 300 is movably mounted on the lifting linear module 140, such that the conveying mechanism 300 is connected to the second linear module 120 via the lifting linear module 140. Simultaneously, the lifting linear module 140 extends vertically along a direction perpendicular to the extension direction of the second linear module 120, and the conveying mechanism 300 can controllably move vertically along the extension direction of the lifting linear module 140. This allows the conveying mechanism 300 to grip and move the product under test vertically, thereby enabling the connector of the product under test to be pressed into or removed from the electrical testing cavity 401.

[0059] It should be noted that the transmission direction can be along a straight line, or it can be a direction composed of multiple straight lines and extending in a bend, as shown in the embodiment in the figure. That is, the first straight line module 110 and the third straight line module 130 are arranged in parallel, and their extension directions are perpendicular to the extension direction of the second straight line module 120. This saves the space occupied by the continuity test system 10 and makes the layout of the continuity test system 10 more compact.

[0060] Furthermore, the number of shaping platform 200, conveying mechanism 300, and electrical testing platform 400 is not limited to one each; multiple of each can be present. Figure 1 and Figure 2 As shown, two shaping platforms 200 are mounted side-by-side on the first linear module 110, and two conveying mechanisms 300 are mounted side-by-side on the second linear module 120. There are two lifting linear modules 140, with each conveying mechanism 300 mounted on a corresponding lifting linear module 140. Furthermore, two electrical testing platforms 400 are mounted side-by-side on the third linear module 130. This configuration allows the continuity testing system 10 of this application to perform shaping and continuity testing on multiple products under test simultaneously, improving testing efficiency.

[0061] like Figure 3 As shown, in some embodiments, the shaping platform 200 includes a first support plate 210 and a shaping mechanism 220, with the shaping mechanism 220 mounted on the edge of the first support plate 210. The first support plate 210 is movably mounted on the first linear module 110. The first support plate 210 is used to support the product to be tested and to fix the product body of the product to be tested. The first support plate 210 is provided with a plurality of suction cups 211 for adsorbing the product body. Preferably, the first support plate 210 is also provided with a plurality of fixing posts 212 for fixing the product body, so that the product body of the product to be tested can be fixed by the fixing posts 212 while being adsorbed by the suction cups 211 onto the first support plate 210, thereby being more firmly fixed onto the first support plate 210.

[0062] In one implementation, such as Figure 4As shown, the shaping mechanism 220 includes a support base 221, a pressure head assembly 222, two first drive elements 223, and two push head assemblies 224. The support base 221 is located on the upper side of the first support plate 210. The pressure head assembly 222 is movably inserted through the support base 221 and spaced apart from the first support plate 210 in the height direction. When the main body of the product to be tested is placed on the first support plate 210, the connector is located between the pressure head assembly 222 and the first support plate 210. The two push head assemblies 224 are arranged relatively apart, and each push head assembly 224 is connected to a corresponding first drive element 223. The first drive element 223 can be a cylinder or a hydraulic cylinder, etc., and is not specifically limited. Furthermore, each pusher assembly 224 can approach each other under the drive of a corresponding first drive element 223 to clamp the connector, thereby limiting the displacement of the connector in the horizontal direction (as indicated in the figure); at the same time, each pusher assembly 224 is movably connected to the pressure head assembly 222. While the first drive element 223 drives the two pusher assemblies 224 to approach each other, it can also drive the pressure head assembly 222 to move downward, thereby limiting the displacement of the connector in the vertical direction (as indicated in the figure) and pressing down on the connector, thereby completing the shaping of the connector.

[0063] like Figure 4 and Figure 5 As shown, each pusher assembly 224 includes a pusher 2241 and a first wedge block 2242 fixedly connected to each other. The pressure head assembly 222 includes a pressure block 2221 and a second wedge block 2222. Each first wedge block 2242 is coupled to the pressure block 2221 through the second wedge block 2222. Specifically, the second wedge block 2222 is disposed on the upper side of the pressure block 2221, and the pressure block 2221 is spaced apart from the first support plate 210. The support base 221 has a mounting position 2211. Each push head 2241 is disposed in the mounting position 2211 and on opposite sides of the pressure block 2221. Each first wedge block 2242 is partially inserted into the mounting position 2211, and one end of each first wedge block 2242 inserted into the mounting position 2211 is fixedly connected to a corresponding push head 2241 by a screw. Each push head 2241 has a clamping part 2241a for clamping the connector. The two clamping parts 2241a are located on opposite sides of the pressure block 2221 in the horizontal direction. Each first wedge block 2242 can drive the push head 2241 to move in the mounting position 2211 toward or away from the pressure block 2221 under the drive of the first driving element 223, so that the clamping part 2241a can clamp or release the connector.

[0064] Each first wedge 2242 has a first sliding surface 2242a on the side near the second wedge 2222. Correspondingly, the second wedge 2222 has two second sliding surfaces 2222a symmetrically arranged at intervals along the same direction as the moving direction of the pusher assembly 224 (i.e., the horizontal direction shown in the figure). Each first sliding surface 2242a is parallel to a corresponding second sliding surface 2222a. The distance between the two first sliding surfaces 2242a gradually increases in the top-to-bottom direction.

[0065] Preferably, the side wall of the support base is also provided with a through hole 2212 communicating with the mounting position 2211. The pressure block 2221 is partially exposed in the through hole 2212, and the clamping part 2241a of the push head 2241 is also located outside the mounting position 2211, so that the clamping parts 2241a of the two push heads, the pressure block 2221, the first support plate 210 and the support base 221 together form a shaping gap 2223 outside the support base 221 for accommodating the connector. The connector can be placed in the shaping gap 2223 and one end of it abuts against the support base 221 so that it can be shaped.

[0066] More preferably, the shaping mechanism 220 further includes a first linear guide assembly 225, which includes a first guide block 2251 and a first guide rail 2252. The first guide rail 2252 is fixedly mounted on the side wall of the mounting position 2211. The first guide block 2251 is fixedly connected to the first wedge block 2242 and is movably limited on the first guide rail 2252. This allows the first wedge block 2242, the pusher head 2241, and the first guide block 2251 to move together along the first guide rail 2252 when the first wedge block 2242 is driven by the first driving element 223 to move relative to the second wedge block 2222, thereby improving the smoothness of the pusher head 2241's movement.

[0067] Furthermore, the shaping mechanism 220 also includes a first elastic element 226, and the second wedge block 2222 is connected to the push head 2241 through the first elastic element 226. The first elastic element 226 can be an elastic element such as a spring, and there is no particular limitation here.

[0068] Thus, when the two pusher assemblies 224 approach each other, the first sliding surface 2242a of each pusher 2241 can abut against a corresponding second sliding surface 2222a and slide relative to the second sliding surface 2222a, so as to push the second wedge block 2222 and the pressure block 2221 to move downward together, thereby shaping the connector placed in the shaping gap 2223 in the height direction, and the clamping part 2241a of the two pushers 2241 can clamp the connector, thereby shaping the connector in the horizontal direction.

[0069] Meanwhile, the first elastic element 226 undergoes a recoverable deformation under the downward pressure of the second wedge block 2222; when the two pushers 2241 move away from each other, the first sliding surface 2242a can slide in the opposite direction relative to the corresponding second sliding surface 2222a. At this time, the elastic deformation of the first elastic element 226 is restored, thereby driving the second wedge block 2222 and the pressure block 2221 to move upward together, so that the connector can be removed from the forming gap 2223.

[0070] It is worth noting that the number of push head components 224 can be only one, but in this case, the connector can only be shaped in the height direction. The number of push head components 224 can also be an even number greater than two, in which case the shaping can be performed in both the horizontal and height directions at the same time, and the shaping effect is better. As long as they can be set in pairs and can achieve the purpose of simultaneously clamping the connector and pushing the pressure block 2221 downward.

[0071] Thus, through the above design, the main body and connector of the product under test can be fixed by the first support plate 210 and the pusher assembly 224 respectively, so that the main body and connector are positioned separately, avoiding repeated pulling of the product's wiring harness. During shaping, the driving force of the first driving element 223 can be decomposed into forces in multiple directions by driving the pusher assembly 224 in only one direction. This achieves the purpose of simultaneously fixing the connector and the mating connector and shaping them in both the height and horizontal directions. This makes the structure of the shaping platform 200 simple and reliable, eliminating the need for multiple drive structures and facilitating maintenance.

[0072] In some embodiments, such as Figure 6 As shown, the conveying mechanism 300 includes a bracket 310, a second drive element 320, an adsorption assembly 330, and a gripper assembly 340. The bracket 310 is movably mounted on the lifting linear module 140. The second drive element 320 and the gripper assembly 340 are fixedly mounted on the bracket 310. The adsorption assembly 330 is connected to the second drive element 320. The second drive element 320 is the same as the first drive element 223 and can also be a drive source such as a cylinder or hydraulic cylinder. The second drive element 320 is used to drive the adsorption assembly 330 to move up and down. The adsorption assembly 330 includes a hanger 331 and a suction plate 332 located at the bottom of the hanger 331 for adsorbing the main body of the product to be tested. The gripper assembly 340 has grippers 341 for clamping connectors. The number of grippers 341 is at least two. The two grippers 341 are arranged opposite each other and can be controllably brought closer together to clamp the connectors.

[0073] Thus, after the shaping platform 200 completes the shaping of the connector, the first linear module 110 transfers the shaping platform 200, which carries the product to be tested, from the shaping work to the photographing station 12. At this time, the shaping platform 200 is located below the transport mechanism 300. The adsorption component 330 of the transport mechanism 300 moves downward relative to the gripper component 340, so that the adsorption component 330 and the gripper component 340 form a maximum height difference of 15mm. This allows the suction plate 332 to adsorb the upper surface of the product body before the gripper 341 of the gripper component 340 clamps the connector. In this way, by using the adsorption component 330 and the gripper component 340 to perform segmented and precise positioning of the product body and the connector, the transport mechanism 300 can maintain the relative position of the product body and the connector during the transfer of the product to be tested from the shaping platform 200, avoiding relative displacement of the product body and the connector during the transfer process. This lays the foundation for the connector to be successfully pressed into the electrical testing cavity 401 in subsequent processes. Meanwhile, because the installation position and height of the connectors on the product body are different in products of different sizes and specifications, the segmented and precise positioning of the product body and connectors can also adapt to products of different specifications, thus avoiding the pulling and rigging of the cables between the product body and the connectors of the product under test.

[0074] Preferably, the conveying mechanism 300 further includes a rotating component 350, which is mounted on the support 310 and located between the support 310 and the gripper assembly 340. The rotating component 350 drives the gripper assembly 340 to rotate about an axis perpendicular to the transmission direction (i.e., the direction shown by the dotted line in the figure). This allows for angle adjustment of the connector while the conveying mechanism 300 transfers the product to be tested above the electrical testing platform 400, enabling the connector to be pressed more accurately into the electrical testing cavity 401.

[0075] Better, such as Figure 7 As shown, the gripper assembly 340 also has a pusher block 342. The pusher block 342 can be controllably moved relative to the gripper 341 along an axis direction that is coplanar with the transmission direction and perpendicular to the transmission direction (the direction shown by the dotted line in the figure). When the gripper 341 clamps the connector for taking a picture, the pusher block 342 can also move towards the camera 500 to hold the connector, so that the relatively soft connector can be firmly clamped on the gripper 341, avoiding deformation of the connector when the camera 500 takes a picture and affecting the picture result.

[0076] In some embodiments, such as Figure 8As shown, the electrical testing platform 400 includes a base 410, a second support plate 420, a third drive element 440, and an electrical testing mechanism 450. The electrical testing cavity 401 is located within the electrical testing mechanism 450. The base 410 is movably mounted on the third linear module 130 and can move along the extension direction of the third linear module 130. The second support plate 420 is parallel to the base 410 and movably connected to the base 410 via four guide pillars 430. The third drive element 440 is mounted on the base 410 and connected to the second support plate 420. The third drive element 440 can also be a cylinder or hydraulic cylinder, etc., used to drive the second support plate 420 to move up and down relative to the base 410. When the transport mechanism 300 transfers the product under test to the electrical testing platform 400, and before the adsorption component 330 of the transport mechanism 300 releases the product body and the gripper component 340 releases the connector, the second support moves upward to support the lower surface of the product body. This allows the product under test to maintain the relative position between the product body and the connector after the connector is shaped to the maximum extent during the process of being transferred from the adsorption component 330 to the electrical testing platform 400, so as to ensure that the connector can be accurately pressed into the electrical testing cavity 401.

[0077] Similar to the first support plate 210 of the shaping platform 200, the second support plate 420 is also provided with multiple suction cups 211 and / or multiple fixing posts 212. Their function is also to enable the main body of the product under test to be more firmly fixed on the second support plate 420, so as to better maintain the relative position between the connector and the main body of the product under test.

[0078] The electrical testing mechanism 450 includes a fixed block 451, a pre-pressing block 452, and a final pressing block 454. The fixed block 451 is fixedly located at the edge of the base 410. The pre-pressing block 452 is parallel to and spaced apart from the fixed block 451. One surface of the pre-pressing block 452 is opposite to one surface of the fixed block 451, together forming the electrical testing cavity 401. The second support plate 420 is raised upwards so that its maximum reach is below the tops of the fixed block 451 and the pre-pressing block 452. The pre-pressing block 452 is movably connected to the fixed block 451 via a slider 453. The slider 453 is movably mounted on the upper end of the fixed block 451, allowing the pre-pressing block 452 to reciprocate along a pressing direction (as indicated in the figure) on the fixed block 451 via the slider 453, thereby changing the dimensions of the electrical testing cavity 401 in the pressing direction.

[0079] In one embodiment, such as Figure 9As shown, a fourth driving element 455 and a trajectory guide block 456 are fixedly mounted on the fixed block 451. The trajectory guide block 456 is arranged along the height direction (i.e., the direction indicated in the figure). The output end of the fourth driving element 455 is connected to the preload block 452, and the fourth driving element 455 is used to drive the preload block 152 to move up and down relative to the fixed block 451. Preferably, as shown... Figure 10 As shown, the trajectory guide block 456 has a guide surface 4561 on one side. The guide surface 4561 includes a first guide surface 4561a, a second guide surface 4561b, and a third guide surface 4561c connected sequentially along the height direction. The second guide surface 4561b is a curved surface, with its two ends connected to the first guide surface 4561a and the third guide surface 4561c, respectively. In the pressing direction, the distance between the third guide surface 4561c and the plane containing the surface of the pre-pressing block 452 near the fixed block 451 is greater than the distance between the first guide surface 4561a and the plane containing the surface of the pre-pressing block 452 near the fixed block 451. Correspondingly, a sliding body 457 is provided on the pre-compression block 452. The sliding body 457 is preferably a roller that can rotate around its own central axis. The sliding body 457 is rotatably connected to the guide surface 4561. The pre-compression block 452 is connected to the track guide block 456 through the sliding body 457, so that the pre-compression block 152 can move up and down in the height direction under the drive of the fourth drive element 455, and at the same time, it can also drive the sliding body 457 to move up and down in the height direction, so that the sliding body 157 rolls on the guide surface 4561, so that the guide surface 4561 can guide the pre-compression block 452 to move relative to the fixed block 451 in the pressing direction.

[0080] Thus, after the gripper assembly 340 of the conveying mechanism 300 presses the connector into the electrical testing cavity 401, and the product body is placed and fixed on the second support plate 420, when the fourth drive element 455 drives the trajectory guide block 456 to move upward, the second guide surface 4561b and the third guide surface 4561c can sequentially contact the sliding body 457, thereby causing the pre-pressing block 452 to move in the pressing direction toward the fixing block 451, so as to hold the connector against the electrical testing cavity 401, thereby preventing it from falling off. Simultaneously, the second support plate 420 is raised and fixes the product body. At this time, the gripper assembly 340 of the conveying mechanism 300 releases the connector, so that the product under test remains stationary when it is transferred from the conveying mechanism 300 to the electrical testing platform 400. Instead, the second support plate 420 and the pre-pressure block 452 of the electrical testing platform 400 move, achieving a seamless transfer of the product under test to the electrical testing platform 400. This ensures that the relative position between the connector and the product body is maintained after the connector has been shaped. Then, when the fourth driving element 455 drives the trajectory guide block 456 downward, the second guide surface 4561b and the first guide surface 4561a sequentially contact the sliding body 457, causing the pre-pressure block 452 to move away from the fixed block 451 along the pressing direction. This allows the pre-pressure block 452 to release the connector, thus removing it from the electrical testing cavity 401.

[0081] Thus, through the above design, within the narrow space of the electrical measuring mechanism 450, the fourth driving element 455 can drive the trajectory guide block 456 to move up and down, thereby driving the pre-pressure block 452 to move in the horizontal pressing direction, thereby converting the displacement in the height direction into the displacement in the horizontal direction, saving the space occupied by the electrical measuring mechanism 450.

[0082] In a preferred embodiment, please refer to [link / reference needed]. Figure 9 The slider 453 is connected to the fixed block 451 via a second elastic element 458. The second elastic element 458 is configured to provide an elastic force that allows the pre-press block 452 to move towards the fixed block 451 to press against the connector when the pre-press block 452 moves away from the fixed block 451 along the pressing direction. When the track guide block 456 moves the pre-press block 452 away from the fixed block 451 along the pressing direction, the slider 453 also moves away from the fixed block 451, at which point the second elastic element 458 undergoes a recoverable deformation. When the track guide block 456 moves the pre-press block 452 towards the fixed block 451 along the pressing direction, the deformation of the second elastic element 458 recovers.

[0083] Thus, by connecting the slider 453 to the fixed block 451 via the second elastic element 458, the force exerted by the pre-pressure block 452 on the connector is the elastic force generated by the second elastic element 458, thereby allowing the pre-pressure block 452 to gently pre-pressure the connector and avoiding damage to the connector due to excessive pre-pressure.

[0084] In one embodiment, combined with Figure 8 and Figure 11 As shown, the final pressing block 454 is a long strip structure that is movably disposed on the second support plate 420 along the pressing direction, and a fifth driving element 459 is provided at the bottom of the second support plate 420. The fifth driving element 459 can also be a cylinder or a hydraulic cylinder. The fifth driving element 459 is connected to the final pressing block 454, so that the final pressing block 454 can be driven by the fifth driving element 459 to move relative to the second support plate 420 along the pressing direction on the second support plate 420.

[0085] The final pressure block 454 is used to move the connector closer to the fixing block 451 along the pressing direction after it has been pre-pressed and fixed by the pre-pressure block 452. This allows one end of the final pressure block 454 to also abut against the connector, so that the opposite sides of the connector are completely abutted against the side wall of the electrical test cavity 401. This allows the contacts on the connector to fully contact the conductive parts provided on the side wall of the electrical test cavity 401, thus enabling the connector to start conducting continuity tests smoothly.

[0086] Preferably, a second linear guide assembly 460 is mounted on the second support plate 420. The second linear guide assembly 460 includes a second guide block 461 and a second guide rail 462. The second guide block 461 is movably mounted on the second guide rail 462 and can reciprocate along the second guide rail 462. The second guide rail 462 is fixedly mounted on the lower side of the final pressing block 454, so that the final pressing block 454 can also move smoothly relative to the second support plate 420.

[0087] Furthermore, such as Figure 12 As shown, due to the small size of the connector, in order for the pre-compression block 452 and the final compression block 454 to contact the connector simultaneously, the pre-compression block 452 has a pre-compression pin 4521 with an outer diameter slightly smaller than that of the connector. During pre-compression fixing of the connector, the pre-compression pin 4521 holds the connector. A clearance groove 4541 is provided at the end of the final compression block 454 near the electrical testing cavity 401. When the final compression block 454 moves to a position near the electrical testing cavity 401 and holds the connector, the portion of the pre-compression pin 4521 that holds the connector is precisely accommodated in the clearance groove 4541.

[0088] Thus, with a small connector size, the above design allows both the pre-pressure block 452 and the final pressure block 454 to directly abut against the connector. Compared to the final pressure block 454 abutting against the pre-pressure block 452, where the pre-pressure block 452 transmits the abutting force applied by the final pressure block 454 to the connector, the transmission of the abutting force is more stable and ensures that the contact point of the connector is fully in contact with the conductive part in the electrical test cavity 401, thereby ensuring the test effect.

[0089] Combination Figure 1 and Figure 2 As shown, the working process of the above-mentioned continuity test system 10 is as follows:

[0090] The first step is to use the shaping platform 200 to shape the irregularly shaped connectors in the product to be tested.

[0091] The second step is to transfer the shaping platform 200 carrying the product to be tested from the first linear module 110 to the photographing station 12 after the product to be tested is transferred to the transport mechanism 300 by the transport structure. Then, the camera 500 takes a picture of the product to be tested to obtain the XY coordinate adjustment parameters of the product to be tested relative to the electrical testing platform 400.

[0092] The third step is to transfer the product under test to the electrical testing station 13 by the second linear module 120 after taking the picture. The system adjusts the position of the electrical testing platform 400 according to the XY coordinate adjustment parameters obtained by the camera 500, so that the handling mechanism 300 can smoothly transfer the product under test to the electrical testing platform 400 and press the connector into the electrical testing cavity 401 for continuity testing.

[0093] Thus, by setting up a shaping platform 200 in the continuity testing system 10, irregularly shaped connectors can be shaped to within the theoretical range. Throughout the entire process, the shaping platform 200, the conveying mechanism 300, and the electrical testing platform 400 all use segmented precise positioning to position the product body and connectors separately, ensuring that the shape of the connectors after shaping and the relative position between the product body and the connectors remain unchanged. This allows the connectors to be precisely pressed into the electrical testing cavity 401 of the electrical testing platform 400, avoiding mutual pulling between the connectors and the product body's wiring, improving pressing accuracy, ensuring connector crimping continuity, and effectively improving testing accuracy. Furthermore, the aforementioned continuity testing system 10 is a fully automated production line, enabling the shaping, transfer, and continuity testing processes to be completed automatically. The cycle time of each process is optimized, resulting in a high degree of automation, reducing labor costs, and significantly improving testing efficiency.

[0094] Finally, it should be noted that the technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0095] The above-described embodiments are merely one implementation of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
