Description

Technical Field

[0001] This application relates to the field of product testing technology, and in particular to a crimping mechanism and testing device. Background Technology

[0002] In the fields of electronic components, chips, and digital products, products need to be tested before packaging to check whether their functions are normal. For example, when testing products under test such as display modules, chips, and battery cells, it is necessary to electrically connect them to the product under test through a crimping module to perform power-on and signal testing.

[0003] Currently, products under test (DUTs) often have different testing requirements during the testing process. Generally, when different tests are required, the DUT is transferred to different testing machines for different functional tests. However, this testing method is too costly and cumbersome. In addition, during the pressing process of the crimping module onto the DUT, the fit between the crimping module and the DUT is poor, which seriously affects the test quality of the DUT. Utility Model Content

[0004] Therefore, it is necessary to provide a crimping mechanism and testing device to address the problems of excessively high testing costs, cumbersome testing procedures, and poor adhesion between the crimping module and the product under test for different testing requirements.

[0005] A crimping mechanism, the crimping mechanism comprising:

[0006] The machine tool has a platform for carrying the product to be tested.

[0007] At least two crimping modules are provided, and multiple crimping modules are rotatably mounted on the machine platform. Any crimping module can be rotated to a position opposite to the platform and can be crimped onto the product to be tested. Each crimping module includes at least one crimping head assembly, which includes a crimping head and a flexible connector disposed near the crimping head.

[0008] In one embodiment, the flexible connector includes a plurality of stacked connecting pieces, which are spaced apart in their stacking direction. One of the connecting pieces is connected to the pressure head, and at least one connecting rod is provided between two adjacent connecting pieces. The connecting rod extends toward the stacking direction of the plurality of connecting pieces and is deformable.

[0009] In one embodiment, there are multiple connecting rods, and at least two connecting rods between two adjacent layers of connecting plates are staggered in the circumferential direction of the connecting plates.

[0010] In one embodiment, the cross-sections of the connecting rods are the same or gradually change in the stacking direction of the plurality of connecting pieces.

[0011] In one embodiment, the flexible connector includes two first collars and a second collar, the two first collars being respectively disposed at opposite ends of the second collar, and each opposite end of the second collar having an insertion groove.

[0012] The first collar has a protruding insertion rod, which is inserted into the corresponding insertion slot with a gap.

[0013] In one embodiment, at least two of the insertion slots at opposite ends of the second collar are misaligned in the circumferential direction of the second collar.

[0014] In one embodiment, the crimping mechanism includes a mounting bracket rotatably mounted on the machine base;

[0015] There are two crimping modules, which are located on opposite sides of the mounting frame. The crimping modules can move toward or away from the platform.

[0016] In one embodiment, the crimping module includes a body and a plurality of crimping head assemblies arrayed on the body. The body is rotatably mounted on the machine platform, and when the crimping module moves toward the platform, the crimping heads can crimp onto the product under test and are electrically connected to the product under test.

[0017] In one embodiment, the body includes a bottom plate, a top plate, and a plurality of side plates connecting the bottom plate and the top plate. The bottom plate, the top plate, and the plurality of side plates are arranged to form an accommodating space. The bottom plate is provided with a plurality of guide holes corresponding to the plurality of pressure heads.

[0018] The pressure head assembly further includes a guide rod, which is movably inserted into the guide hole along its extension direction, and the guide rod is at least partially housed in the accommodating space. The guide rod is connected to the pressure head, and the flexible connector is provided at the connection between the guide rod and the pressure head.

[0019] A testing apparatus, the testing apparatus comprising:

[0020] The crimping mechanism as described in any of the above technical solutions; and

[0021] The testing mechanism is communicatively connected to the crimping mechanism.

[0022] The aforementioned crimping mechanism and testing device allow any crimping module to rotate to a position opposite to the platform and crimp onto the product under test (DUT) to perform electrical crimping tests. Since multiple crimping modules are rotatably mounted on the machine, any module can rotate to a position opposite to the platform, allowing for switching between different crimping modules to perform crimping tests on the DUT. Furthermore, crimping modules with different testing functions can meet the diverse testing needs of the DUT. Different functional tests on the DUT can be performed using only the crimping mechanism, simplifying the testing process and reducing testing costs. Additionally, the crimping head assembly includes a crimping head and a flexible connector. When the crimping head crimps onto the DUT, the flexible connector can undergo flexible deformation, allowing the crimping head to adaptively conform to the surface of the DUT, improving the quality of the crimping test.

[0034] 200. Product to be tested. Detailed Implementation

[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are 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 this application. However, this application can be implemented 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 this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] Furthermore, where the terms "first" and "second" appear, these terms are 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 with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," 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 expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via 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 first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] It should be noted that if 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. If 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. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0042] See Figures 1-3 As shown, this application provides a crimping mechanism 100, which includes a machine base 110 and at least two crimping modules 120. The machine base 110 has a platform 111 for supporting the product under test 200. The platform 111 may have a supporting cavity to stably support the product under test 200. The crimping mechanism 100 is used to perform electrical crimping tests on the product under test 200 to determine its pass / fail status. The product under test 200 may be a display module, chip, battery unit, etc. This application does not limit the specific component type of the product under test 200.

[0043] Multiple crimping modules 120 are rotatably mounted on the machine base 110. Any crimping module 120 can rotate to a position opposite to the platform 111 and crimp onto the product under test 200. For example, if any crimping module 120 can rotate to a position near the upper part of the platform 111, such that the crimping portion of the crimping module 120 corresponds to the test portion of the product under test 200, the crimping module 120 can be crimped onto the product under test 200 to perform a crimp test. It should be noted that the multiple crimping modules 120 are movably mounted on the machine base 110, and all multiple crimping modules 120 can move towards or away from the platform 111. For example, if any crimping module 120 rotates to a position opposite to the product under test 200 and moves towards the platform 111, an electrical crimp test can be performed on the product under test 200 using the crimping module 120. After the product under test 200 is tested, the crimping module 120 moves away from the platform 111, separating from the product under test 200. This facilitates the replacement of different crimping modules 120 for crimping tests on the product under test 200 and the replacement of the product under test 200 itself. Since multiple crimping modules 120 are rotatably mounted on the machine base 110, any crimping module 120 can be rotated to a position opposite to the platform 111, allowing for the switching of different crimping modules 120 to perform crimp tests on the product under test 200. Furthermore, crimping modules 120 with different testing functions can meet the diverse testing needs of the product under test 200. Different functional tests of the product under test 200 can be performed using only the crimping mechanism 100, simplifying the testing process and reducing testing costs.

[0044] The crimping module 120 includes at least one crimping head assembly 121, which includes a crimping head 122 and a flexible connector 123. The flexible connector 123 is disposed close to the crimping head 122. The crimping head 122 is used for electrically crimping the product under test 200. When the crimping head 122 is crimped onto the product under test 200, the flexible connector 123 can undergo flexible deformation, and the crimping head 122 adaptively conforms to the surface of the product under test 200, thereby improving the crimping test quality of the product under test 200.

[0045] In one embodiment, see further. Figures 4-7As shown, the flexible connector 123 includes a plurality of stacked connecting pieces 1231, which are spaced apart in their stacking direction. One connecting piece 1231 is connected to the pressure head 122 to connect the flexible connector 123 to the pressure head 122. At least one connecting rod 1232 is provided between two adjacent connecting pieces 1231. The connecting rod 1232 extends in the stacking direction of the plurality of connecting pieces 1231 and is deformable. It should be noted that the connecting rod 1232 is a non-rigid component. For example, the connecting rod 1232 can be made of plastic rod, silicone rod, or other deformable material. This application does not limit the specific material type of the connecting rod 1232.

[0046] The aforementioned crimping mechanism 100 has a connecting rod 1232 between two adjacent connecting pieces 1231, and a flexible connector 123 is connected to the crimping head 122. When the crimping head 122 crimps the product under test 200, the connecting rod 1232 deforms, causing the two adjacent connecting pieces 1231 to misalign. This allows the flexible connector 123 to deform flexibly, and the crimping head 122 to adaptively conform to the surface of the product under test 200, thereby improving the crimping test quality of the product under test 200.

[0047] Specifically, see Figures 4-7 As shown, there are multiple connecting rods 1232, and at least two connecting rods 1232 between adjacent connecting plates 1231 are staggered in the circumferential direction of the connecting piece 1231. For example, as in one embodiment, see [reference needed]. Figure 4 As shown, the connecting rod 1232 has a sheet-like structure, connecting two adjacent connecting pieces 1231 into one unit, and at least two connecting rods 1232 between two adjacent connecting pieces 1231 are staggered in the circumferential direction of the connecting piece 1231. As in another embodiment, see [reference needed]. Figure 5 As shown, the connecting rod 1232 has a rod-shaped structure, with multiple connecting rods 1232 between two adjacent connecting pieces 1231, and at least two connecting rods 1232 between two adjacent connecting pieces 1231 are staggered. In yet another embodiment, see [reference needed]. Figure 6 As shown, the connecting rod 1232 is a rod-shaped structure, and connecting rods 1232 are provided at the corners of two adjacent connecting pieces 1231. The two adjacent connecting pieces 1231 are connected into one piece by multiple connecting rods 1232.

[0048] In the process of flexible deformation of the flexible connector 123, the above-mentioned crimping mechanism 100 has multiple staggered connecting rods 1232 that limit the misalignment of multiple connecting pieces 1231, so as to prevent the flexible connector 123 from undergoing permanent deformation due to excessive misalignment of multiple connecting pieces 1231. That is, the multiple staggered connecting rods 1232 can make the flexible connector 123 deform within a predetermined stroke, so as to ensure that the pressure head 122 can adaptively fit the surface to be tested, and the flexible connector 123 can elastically reset.

[0049] Further, see Figures 4-7 As shown, in the stacking direction of the plurality of connecting pieces 1231, the cross-section of the connecting rod 1232 is the same, or the cross-section of the connecting rod 1232 gradually changes. Exemplarily, as in one embodiment, see [reference needed]. Figures 4-6 As shown, in the stacking direction of the multiple connecting pieces 1231, the cross-section of the connecting rod 1232 is the same, such as the connecting rod 1232 being a square rod or a round rod. As in another embodiment, see [reference needed]. Figure 7 As shown, the cross-section of the connecting rod 1232 gradually changes, such as the connecting rod 1232 increasing or decreasing in the direction from one of the connecting pieces 1231 toward the adjacent connecting piece 1231. It should be understood that the gradual change in the cross-section of the connecting rod 1232 should be interpreted as follows: in the stacking direction of the multiple connecting pieces 1231, the cross-section of the connecting rod 1232 gradually increases; or, the cross-section of the connecting rod 1232 gradually decreases; or, the cross-section of the connecting rod 1232 remains constant initially, then gradually increases, and then remains constant again; or, the cross-section of the connecting rod 1232 remains constant initially, then gradually decreases, and then remains constant again, etc.

[0050] The aforementioned crimping mechanism 100, by defining the cross-sectional shape of the connecting rod 1232, allows the connecting rod 1232 to deform or at least partially deform when the crimping head 122 is pressed against the product under test 200 due to the contact force between the crimping head 122 and the product under test 200. This enables the flexible connector 123 to undergo flexible deformation, and the crimping head 122 to adaptively conform to the surface of the product under test 200, thereby improving the crimping test quality of the product under test 200.

[0051] In one embodiment, see Figure 1 , Figure 2 , Figure 3 and Figure 8As shown, the flexible connector 123 includes two first collars 1233 and a second collar 1234. The two first collars 1233 are respectively disposed at opposite ends of the second collar 1234. For example, the second collar 1234 has opposite ends, with a first collar 1233 at one end and a first collar 1233 at the other end. Both opposite ends of the second collar 1234 have insertion grooves 1235. The first collar 1233 has a protruding insertion rod 1236. Preferably, the insertion rod 1236 is integrally formed onto the first collar 1233 by injection molding, extrusion, or other methods to simplify the molding process of the first collar 1233 and improve the structural strength of the first collar 1233 and the insertion rod 1236. The plug rod 1236 is inserted into the corresponding plug groove 1235 with a gap. For example, the plug rods 1236 of the two first collars 1233 are respectively inserted into the plug grooves 1235 at opposite ends of the second collar 1234 to realize the connection between the two first collars 1233 and the second collar 1234.

[0052] The aforementioned crimping mechanism 100, due to the gap between the insertion rod 1236 and the insertion groove 1235, when the crimping head 122 is crimped onto the product under test 200, the insertion rod 1236 can undergo flexible deformation under the action of the contact force between the crimping head 122 and the product under test 200, and the crimping head 122 adaptively conforms to the surface of the product under test 200, thereby improving the crimping test quality of the product under test 200.

[0053] Further, see Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, in the circumferential direction of the second ring 1234, at least two insertion slots 1235 at opposite ends of the second ring 1234 are staggered. Thus, during the flexible deformation of the flexible connector 123, the staggered insertion slots 1235 limit the misalignment of the insertion rod 1236 inserted within them, preventing the flexible connector 123 from undergoing permanent deformation due to excessive misalignment of the insertion rod 1236. In other words, the staggered insertion slots 1235 allow the flexible connector 123 to deform within a predetermined stroke, ensuring that the pressure head 122 can adaptively conform to the surface to be measured, while also enabling the flexible connector 123 to elastically return to its original position.

[0054] In one embodiment, see Figures 1-3 As shown, the crimping mechanism 100 includes a mounting frame 130, which is rotatably mounted on the machine base 110. The mounting frame 130 is connected to a rotary drive source, allowing it to rotate. Two crimping modules 120 are located on opposite sides of the mounting frame 130. The two crimping modules 120 are positioned along... Figure 1As shown, the crimping modules 120 are spaced approximately vertically, and can move towards or away from the platform 111. For example, if the two crimping modules 120 are defined as a first crimping module and a second crimping module, both the first and second crimping modules are mounted on the mounting bracket 130, and the first and second crimping modules are positioned along... Figure 1 The components are arranged approximately vertically. First, the first crimping module rotates to the side closer to the platform 111, facing the product under test 200, while the second crimping module rotates to the side away from the platform 111. Next, the mounting bracket 130 moves both the first and second crimping modules towards the platform 111, and the first crimping module crimps onto the product under test 200, performing an electrical crimp test. After the first crimping module completes its test on the product under test 200, the mounting bracket 130 moves both the first and second crimping modules away from the platform 111, separating them. Then, driven by the mounting bracket 130, the first and second crimping modules move relative to the platform 110 along... Figure 1 As shown, the first crimping module rotates 180° within the plane of the paper, moving to the side closer to the stage 111 and opposite the product under test 200, while the second crimping module rotates to the side away from the product under test 200. Next, the mounting bracket 130 moves both the first and second crimping modules towards the stage 111, and the second crimping module crimps onto the product under test 200, performing an electrical crimp test. Finally, after the second crimping module completes its test on the product under test 200, the mounting bracket 130 moves both the first and second crimping modules away from the stage 111, separating the second crimping module from the product under test 200. Thus, by rotating and moving the first and second crimping modules, two crimp tests on the product under test 200 can be completed.

[0055] The aforementioned crimping mechanism 100 can switch between two crimping modules 120 to perform crimping tests on the product under test 200. The two crimping modules 120 can meet the diverse testing needs of the product under test 200. Different functional tests of the product under test 200 can be performed using only the crimping mechanism 100, simplifying the testing process and reducing the testing cost of the product under test 200.

[0056] It should be noted that the specific number of crimping modules 120 is not limited to the two provided in the above embodiments. The number of crimping modules 120 can also be three, four, or other numbers. This application does not limit the specific number of crimping modules 120. If the number of crimping modules 120 is other, the multiple crimping modules 120 are spaced apart along the circumferential direction of the mounting bracket 130. The crimping action of the multiple crimping modules 120 on the product under test 200 can be performed according to the above embodiments, which will not be repeated here. Furthermore, when the number of crimping modules 120 is other, and at least two crimping modules 120 have different testing functions, the crimping mechanism 100 can meet the different functional testing requirements of the product under test 200. When the number of crimping modules 120 is other, and multiple crimping modules 120 have the same testing function, the crimping mechanism 100 can perform multiple electrical crimping tests on the product under test 200 to improve the testing reliability of the product under test 200.

[0057] In one embodiment, see Figures 1-3 As shown, the crimping module 120 includes a body 124 and multiple crimping head assemblies 121. The multiple crimping head assemblies 121 are arrayed on the body 124 and spaced apart. The body 124 is rotatably mounted on the machine base 110. For example, if the body 124 is mounted on a mounting bracket 130, the body 124 can rotate relative to the machine base 110 through the mounting bracket 130. When the crimping module 120 moves toward the platform 111, the crimping head 122 can crimp onto the product under test 200, and the crimping head 122 is electrically connected to the product under test 200 to realize the electrical crimping test of the product under test 200 by the crimping mechanism 100. The multiple crimping head assemblies 121 can improve the efficiency of the electrical crimping test of the product under test 200.

[0058] Specifically, see Figures 1-3 As shown, the main body 124 includes a base plate 1241, a top plate 1242, and multiple side plates 1243. The multiple side plates 1243 connect the base plate 1241 and the top plate 1242, and the base plate 1241, top plate 1242, and multiple side plates 1243 enclose a receiving space 1244. That is to say, the main body 124 is formed by the base plate 1241, top plate 1242, and multiple side plates 1243. At least one of the base plate 1241, top plate 1242, and side plates 1243 can be connected to the mounting frame 130 by means of screws, welding, etc., to realize the rotational connection between the main body 124 and the machine base 110. The base plate 1241 is provided with multiple guide holes 1245, and the multiple guide holes 1245 correspond to multiple pressure heads 122. In this embodiment, the number of guide holes 1245 is consistent with the number of pressure heads 122.

[0059] The pressure head assembly 121 also includes a guide rod 125, which is movably inserted into a guide hole 1245 along its extension direction. For example, one guide rod 125 is inserted into each guide hole 1245, and the guide rod 125 is at least partially accommodated in the accommodating space 1244. During the movement of the guide rod 125, the top plate 1242 can limit the movement stroke of the guide rod 125 to prevent the guide rod 125 from detaching from the body 124 due to excessive movement. The guide rod 125 is connected to the pressure head 122, and a flexible connector 123 is provided at the connection between the guide rod 125 and the pressure head 122.

[0060] In the aforementioned crimping mechanism 100, during the process of the pressure head 122 pressing the product under test 200, the flexible connector 123 can undergo flexible deformation due to the contact force between the pressure head 122 and the product under test 200. This deformation, combined with the movement of the guide rod 125 within the guide hole 1245, changes the length of the guide rod 125 extending into the accommodating space 1244, allowing the pressure head 122 to adaptively conform to the surface of the product under test 200, thereby improving the crimping test quality of the product under test 200. Furthermore, the guide hole 1245 can limit the movement direction of the guide rod 125, thereby improving the alignment accuracy between the pressure head assembly 121 and the product under test 200, ensuring the reliability of the crimping alignment between the pressure head assembly 121 and the product under test 200, and further improving the crimping test quality of the product under test 200.

[0061] Furthermore, due to the large length-to-diameter ratio of the guide rod 125, i.e., the guide rod 125 is an overall slender shaft, it is prone to wobbling during its movement within the guide hole 1245, leading to a misalignment of the pressing position between the pressure head 122 and the product under test 200. Based on this, in one embodiment, see [reference needed]. Figures 1-3 As shown, a counterweight 140 is provided at the end of the guide rod 125 facing away from the pressure head 122. The counterweight 140 can be a weight, metal block, or other component with a certain mass. Thus, by adding the counterweight 140 to the guide rod 125, the overall weight of the pressure head assembly 121 is increased, thereby improving the stability of the guide rod 125 during its movement, ensuring the accurate alignment of the pressure head 122 with the product under test 200, and ultimately improving the testing reliability of the pressure module 120 for the product under test 200. Furthermore, since the flexible connector 123 is located between the guide rod 125 and the pressure head assembly 121, when the pressure head 122 presses against the product under test 200, the gravitational force applied by the counterweight 140 to the flexible connector 123 is opposite to the abutting force applied by the product under test 200 to the flexible connector 123. This ensures that the flexible connector 123 can undergo flexible deformation, and the pressure head 122 adaptively conforms to the surface of the product under test 200, thereby improving the pressing test quality of the product under test 200.

[0062] Additionally, see Figures 1-3 As shown, this application also provides a testing device, which includes a testing mechanism and a crimping mechanism 100 as described above. The testing mechanism and the crimping mechanism 100 are communicatively connected. For example, the testing mechanism and the crimping mechanism 100 are connected via a signal conduction line. The testing mechanism acquires, analyzes, and provides feedback on the electrical crimping signal of the crimping mechanism 100.

[0063] In the aforementioned testing apparatus, any crimping module 120 can be rotated to a position opposite to the platform 111 and crimped onto the product under test 200 to perform electrical crimping tests on the product under test 200. Since multiple crimping modules 120 are rotatably mounted on the platform 110, any crimping module 120 can be rotated to a position opposite to the platform 111, and different crimping modules 120 can be switched to perform crimping tests on the product under test 200. Furthermore, crimping modules 120 with different testing functions can meet the diverse testing needs of the product under test 200. Different functional tests of the product under test 200 can be performed using only the crimping mechanism 100, simplifying the testing action and reducing the testing cost of the testing apparatus. In addition, the pressure head assembly 121 includes a pressure head 122 and a flexible connector 123. When the pressure head 122 presses against the product under test 200, the flexible connector 123 can undergo flexible deformation, and the pressure head 122 adapts to fit the surface of the product under test 200, thereby improving the pressure test quality of the product under test 200.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are 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.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
