[0038] 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.
[0039] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.
[0040] See Figures 1-3 As shown, the crimping mechanism 100 includes a carrier 110, a first crimping module 120, and a second crimping module 130. The crimping mechanism 100 is used to perform electrical crimping tests on the product under test. The product under test can be a chip, a display module, or other components that require electrical testing. This application does not limit the specific type of component in the product under test.
[0041] The carrier 110 is used to carry the product under test. If the carrier 110 has a carrying cavity, preferably a contoured cavity, the product under test can be placed in the carrying cavity to achieve the carrying and placement of the product under test on the carrier 110. The carrier 110 is provided with a first positioning hole 111 and a second positioning hole 112. Preferably, the carrier 110 is integrally formed with the first positioning hole 111 and the second positioning hole 112 by injection molding, extrusion, or other methods to simplify the molding process of opening the first positioning hole 111 and the second positioning hole 112 on the carrier 110. The product under test has a first testing section and a second testing section. If both the first and second testing sections are integrations of multiple test terminals, and the first and second testing sections are located in different areas of the product under test, for example, in this embodiment, the first testing section is closer to the top of the product under test, and the second testing section is closer to the side of the product under test.
[0042] The first crimping module 120 includes a first floating guide assembly 121 and a floating probe assembly 122. The first crimping module 120 can move toward or away from the carrier 110. When the first crimping module 120 moves toward the carrier 110, the first floating guide assembly 121 can be inserted into the first positioning hole 111, and the floating probe assembly 122 is electrically connected to the first testing section. When performing an electrical crimp test on the first test section of the product under test, the product under test is placed on the carrier 110, and the first crimping module 120 moves toward the carrier 110. The first floating guide component 121 can be inserted into the first positioning hole 111 to guide the movement of the first crimping module 120. Through the floating movement of the first floating guide component 121, the first floating guide component 121 can adaptively insert into the first positioning hole 111, improving the insertion reliability between the first floating guide component 121 and the first positioning hole 111. The floating probe component 122 can adaptively adapt to the crimping position of the first test section, improving the alignment accuracy of the crimping position between the first crimping module 120 and the first test section. It should be noted that in this embodiment, the floating force of the first floating guide component 121 is greater than the floating force of the floating probe component 122. During the electrical crimping test of the first test part of the product under test, the floating probe component 122 first contacts the first test part of the product under test and floats adaptively to the crimping position of the first test part. After the floating probe component 122 contacts the first test part, the first floating guide component 121 then floats and crimps with the product under test to ensure the alignment accuracy of the crimping position between the first crimping module 120 and the first test part, and to avoid defects such as bending or broken needles in the floating probe component 122 due to deviation of the crimping position.
[0043] The second crimping module 130 includes a second floating guide component 131. The first crimping module 120 can move towards or away from the carrier 110. When the second crimping module 130 moves towards the carrier 110, the second floating guide component 131 can be inserted into the second positioning hole 112, and the second crimping module 130 is electrically connected to the second testing section. For example, when performing an electrical crimping test on the second testing section of the product under test, the product under test is placed on the carrier 110, and the second crimping module 130 moves towards the carrier 110. The second floating guide component 131 can be inserted into the second positioning hole 112 to guide the movement of the second crimping module 130. Through the floating movement of the second floating guide component 131, the second floating guide component 131 can adaptively insert into the second positioning hole 112, improving the insertion reliability between the second floating guide component 131 and the second positioning hole 112, thereby improving the crimping position alignment accuracy between the second crimping module 130 and the second testing section.
[0044] The aforementioned crimping mechanism 100 can perform electrical tests on the first test section and the second test section of the product under test through the first crimping module 120 and the second crimping module 130, respectively. During the test, the first floating guide component 121 can guide the crimping position of the first test section, and the floating probe component 122 adapts to the crimping position of the first test section, thereby improving the alignment accuracy of the crimping position between the first crimping module 120 and the first test section. The second floating guide component 131 can guide the crimping position of the second test section, thereby improving the alignment accuracy of the crimping position between the second crimping module 130 and the second test section. While improving the crimping accuracy and reliability of the crimping mechanism 100, it can reduce the risk of damage to the crimping mechanism 100 due to crimping position misalignment.
[0045] In one embodiment, see Figures 1-4As shown, the first crimping module 120 also includes a first base 123. The floating probe assembly 122 includes a body 1221 and a probe group 1222. The body 1221 is disposed on the first base 123, such as by screwing, snap-fitting, or other means. The probe group 1222 is floatingly disposed on the body 1221 and is used for electrical connection with the first testing unit. Thus, the probe assembly 1222 is fixed to the first base 123 by the main body 1221. During the crimping test of the first test part by the first crimping module 120, when the probe assembly 1222 contacts the first test part, the probe assembly 1222 can generate a floating motion, adaptively adjusting the crimping position between the probe assembly 1222 and the first test part. This avoids the phenomenon of poor test results due to the deviation of the crimping position between the probe assembly 1222 and the first test part, improving the alignment accuracy of the crimping position between the probe assembly 1222 and the first test part. Furthermore, the floating of the probe assembly 1222 during the crimping process can buffer the force between the probe assembly 1222 and the first test part, preventing the probe assembly 1222 from bending, breaking, or other defects during the crimping process.
[0046] Further, see Figure 1 , Figure 3 and Figure 4 As shown, the floating probe assembly 122 also includes at least one first elastic element 1223. The probe group 1222 is disposed on the body 1221 via the first elastic element 1223, and the deformation direction of the first elastic element 1223 is consistent with the floating direction of the probe group 1222. Thus, through the elastic deformation of the first elastic element 1223, the probe group 1222 is floating, and the probe group 1222 adapts to the pressing position of the first testing part, improving the alignment accuracy of the pressing position between the probe group 1222 and the first testing part, thereby improving the pressing accuracy and reliability of the pressing mechanism 100.
[0047] Preferably, there are multiple first elastic elements 1223, and the multiple first elastic elements 1223 are arranged at intervals. The multiple first elastic elements 1223 can improve the support reliability of the probe group 1222, and the multiple first elastic elements 1223 cooperate to realize the floating of the probe group 1222, thereby improving the floating performance of the probe group 1222. The first elastic element 1223 can be a spring, an elastic sheet or other elastic element. This application does not limit the specific element type of the first elastic element 1223.
[0048] Specifically, see Figure 1 , Figure 3 and Figure 4As shown, the probe assembly 1222 includes a base 1224, multiple probes 1225, a cover plate 1226, and a pressure plate 1227. The base 1224 is mounted on the body 1221 by welding, screwing, or other means. The probe assembly 1222 is mounted on a first base 123 via the body 1221. The cover plate 1226 is mounted on the body 1221 via a first elastic member 1223. The multiple probes 1225 are movably mounted on the base 1224, and all of the probes 1225 are inserted into the cover plate 1226, with at least a portion of each probe extending beyond the outside of the cover plate 1226. For example, the probes 1225 may be cylindrical, blade-shaped, or the like, and an array of multiple probes 1225 may be arranged on the base 1224. Thus, when the first crimping module 120 moves toward the direction of the first test section, the portion of the probe 1225 extending outward from the cover plate 1226 can be electrically connected to the first test section, thereby realizing the electrical crimping test of the first crimping module 120 on the first test section. Since the cover plate 1226 is disposed on the body 1221 through the first elastic member 1223, and multiple probes 1225 are inserted into the cover plate 1226, during the contact process between the multiple probes 1225 and the first test section, due to the elastic deformation of the first elastic member 1223, the cover plate 1226 can drive the multiple probes 1225 to float and adapt to the crimping position of the first test section, thereby improving the alignment accuracy of the crimping position between the probe group 1222 and the first test section, and thus improving the crimping accuracy and reliability of the crimping mechanism 100.
[0049] Furthermore, the pressure plate 1227 is pressed onto the cover plate 1226, such that the pressure plate 1227 is disposed on the body 1221, and the pressure plate 1227 is located on the side of the cover plate 1226 away from the base 1224. In this way, during the floating process of the cover plate 1226 driving multiple probes 1225, the pressure plate 1227 can restrict the movement of the cover plate 1226, preventing the cover plate 1226 from exceeding the preset position during the floating process, that is, limiting the floating of the cover plate 1226 to a certain range, which can both protect the first elastic element 1223 and ensure the floating accuracy of the probes 1225.
[0050] In one embodiment, see Figure 1 , Figure 3 and Figure 4 As shown, there are multiple first positioning holes 111, and when the product under test is carried on the carrier 110, the multiple first positioning holes 111 are distributed at intervals along the circumferential direction of the first test section. For example, if there are two first positioning holes 111, the two first positioning holes 111 are located on opposite sides of the carrier 110; or if there are four first positioning holes 111, the four first positioning holes 111 are located at the four diagonal positions of the carrier 110. This application does not limit the specific number and position of the first positioning holes 111.
[0051] The first floating guide assembly 121 includes a plurality of first guide members 1211, each corresponding to a plurality of first positioning holes 111. The number and insertion positions of the first guide members 1211 and the first positioning holes 111 correspond, and each first guide member 1211 is a guide post, guide pin, or other structure capable of being inserted into the first positioning hole 111. The first guide members 1211 are floatingly disposed on the first base 123, and can be inserted into the first positioning holes 111.
[0052] When the first pressing module 120 moves toward the first testing section, the first guide member 1211 can be inserted into the first positioning hole 111 to guide the pressing position of the first testing section. Since the first guide member 1211 is floatingly disposed on the first base 123, when the position of the first guide member 1211 deviates from that of the first positioning hole 111, the first guide member 1211 floats and compensates for the position deviation, ensuring the reliability of the insertion and engagement between the first guide member 1211 and the first positioning hole 111. Furthermore, through the cooperation of multiple first guide members 1211 and multiple first positioning holes 111, the alignment and guiding accuracy of the first floating guide assembly 121 for the first pressing module 120 can be improved, further enhancing the pressing accuracy and reliability of the pressing mechanism 100.
[0053] Further, see Figure 1 , Figure 3 and Figure 4 As shown, the first floating guide assembly 121 further includes a first floating seat 1212 and at least one second elastic member 1213. The first floating seat 1212 is disposed on the first base 123, and a plurality of first guide members 1211 are disposed on the first floating seat 1212. The second elastic member 1213 is disposed between the first floating seat 1212 and the first base 123, and the deformation direction of the second elastic member 1213 is consistent with the floating direction of the first guide member 1211. For example, the first floating seat 1212 is connected to the first base 123 via a first connector 1231. The first base 123 is provided with a first receiving groove 1232 for accommodating the second elastic member 1213. The first connector 1231 is received in the first receiving groove 1232, and the second elastic member 1213 is located outside the first connector 1231. Preferably, there are multiple second elastic elements 1213, and the multiple second elastic elements 1213 are arranged at intervals. The support reliability of the first floating seat 1212 can be improved by using multiple second elastic elements 1213. The second elastic element 1213 can be a spring, an elastic sheet or other elastic element. This application does not limit the specific type of the second elastic element 1213.
[0054] The aforementioned crimping mechanism 100, through the elastic deformation of the second elastic element 1213, allows the first floating seat 1212 to float relative to the first base 123. Since multiple first guide elements 1211 are all disposed on the first floating seat 1212, the first floating seat 1212 can drive the multiple first guide elements 1211 to float and compensate for the misalignment between the first guide element 1211 and the first positioning hole 111, ensuring the reliability of the insertion fit between the first guide element 1211 and the first positioning hole 111, thereby improving the alignment and guiding accuracy of the first floating guide assembly 121 for the first crimping module 120.
[0055] In one embodiment, see Figure 1 , Figure 5 and Figure 6 As shown, there are multiple second positioning holes 112, and when the product under test is carried on the carrier 110, the multiple second positioning holes 112 are distributed at intervals along the circumferential direction of the second test section. For example, if there are two second positioning holes 112, the two second positioning holes 112 are located on opposite sides of the carrier 110; or if there are four second positioning holes 112, the four second positioning holes 112 are located at the four diagonal positions of the carrier 110. This application does not limit the specific number and position of the second positioning holes 112.
[0056] The second crimping module 130 also includes a second base 132. The second floating guide assembly 131 includes a plurality of second guide members 1311, which correspond to a plurality of second positioning holes 112. For example, the number and insertion positions of the second guide members 1311 and the second positioning holes 112 are corresponding, and the second guide members 1311 are guide posts, guide pins, or other structures that can be inserted and engaged with the second positioning holes 112. The second guide members 1311 are floatingly disposed on the second base 132, and the second guide members 1311 can be inserted into the second positioning holes 112.
[0057] When the second pressing module 130 moves toward the direction of the second testing section, the second guide member 1311 can be inserted into the second positioning hole 112 to guide the pressing position of the second testing section. Since the second guide member 1311 is floatingly disposed on the second base 132, when the position of the second guide member 1311 deviates from that of the second positioning hole 112, the second guide member 1311 floats and compensates for the position deviation, ensuring the reliability of the insertion and engagement between the second guide member 1311 and the second positioning hole 112. Furthermore, through the cooperation of multiple second guide members 1311 and multiple second positioning holes 112, the alignment and guiding accuracy of the second floating guide assembly 131 for the second pressing module 130 can be improved, further improving the pressing accuracy and reliability of the pressing mechanism 100.
[0058] Further, see Figure 1 , Figure 5 and Figure 6 As shown, the second floating guide assembly 131 further includes a second floating seat 1312 and at least one third elastic member 1313. The second floating seat 1312 is disposed on the second base 132, and a plurality of second guide members 1311 are disposed on the second floating seat 1312. The third elastic member 1313 is disposed between the second floating seat 1312 and the second base 132, and the deformation direction of the third elastic member 1313 is consistent with the floating direction of the second guide members 1311. For example, the second floating seat 1312 is connected to the second base 132 via a second connector 1321. The second base 132 is provided with a second receiving groove 1322 for accommodating the third elastic member 1313. The second connector 1321 is received in the second receiving groove 1322, and the third elastic member 1313 is located outside the second connector 1321. Preferably, there are multiple third elastic elements 1313, and the multiple third elastic elements 1313 are arranged at intervals. The support reliability of the second floating seat 1312 can be improved by using multiple third elastic elements 1313. The third elastic element 1313 can be a spring, an elastic sheet or other elastic element. This application does not limit the specific type of the third elastic element 1313.
[0059] The aforementioned crimping mechanism 100, through the elastic deformation of the third elastic element 1313, allows the second floating seat 1312 to float relative to the second base 132. Since multiple second guide elements 1311 are all disposed on the second floating seat 1312, the second floating seat 1312 can drive the multiple second guide elements 1311 to float and compensate for the misalignment between the second guide elements 1311 and the second positioning hole 112, ensuring the reliability of the insertion fit between the second guide elements 1311 and the second positioning hole 112, thereby improving the alignment and guiding accuracy of the second floating guide assembly 131 for the second crimping module 130.
[0060] Additionally, see Figures 1-3 As shown, this application also provides a testing apparatus, which includes a testing mechanism and a crimping mechanism 100 as described above. The crimping mechanism 100 is electrically connected to the testing mechanism, and the testing mechanism can perform electrical crimping tests on the product under test.
[0061] The aforementioned testing device can perform electrical tests on the first test section and the second test section of the product under test through the first crimping module 120 and the second crimping module 130, respectively. During the test, the first floating guide component 121 can guide the crimping position of the first test section, and the floating probe component 122 adapts to the crimping position of the first test section, thereby improving the alignment accuracy of the crimping position between the first crimping module 120 and the first test section. The second floating guide component 131 can guide the crimping position of the second test section, thereby improving the alignment accuracy of the crimping position between the second crimping module 130 and the second test section. While improving the crimping accuracy and reliability of the crimping mechanism 100, it can reduce the risk of damage to the crimping mechanism 100 due to crimping position misalignment.
[0062] In one embodiment, see Figure 1 As shown, the first crimping module 120 further includes a first signal conducting part 124, and the second crimping module 130 further includes a second signal conducting part 133. Both the first signal conducting part 124 and the second signal conducting part 133 are electrically connected to the testing mechanism. For example, the first signal conducting part 124 is electrically connected to the testing mechanism via a cable, Bluetooth, or other means to feed back the test signal of the first testing part to the testing mechanism. The second signal conducting part 133 is electrically connected to the testing mechanism via a cable, Bluetooth, or other means to feed back the test signal of the second testing part to the testing mechanism. Thus, the test signal of the product under test can be fed back to the testing device via the first signal conducting part 124 and the second signal conducting part 133, enabling the testing device to perform electrical crimping tests on the product under test.
[0063] It should be noted that, in this embodiment, when both the first crimping module 120 and the second crimping module 130 are in contact with the product under test, the first signal conduction unit 124 and the second signal conduction unit 133 are electrically connected, and the test signals of the first crimping module 120 and the second crimping module 130 are fed back to the testing mechanism through the first signal conduction unit 124. Thus, only an external test element needs to be connected to the first signal conduction unit 124 to achieve signal feedback between the first crimping module 120 and the second crimping module 130. This simplifies the number of test feedback elements required for the crimping mechanism 100, reduces the testing cost of the testing device, reduces the overall size of the crimping mechanism 100, and expands the testing scenarios of the testing device.
[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.
