Detailed Description

In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", "front", "rear", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

In order to facilitate the technical solution disclosed in the present invention to be fully understood by those skilled in the art, the following detailed description is made in combination with the specific embodiments, fig. 1 and fig. 2 respectively show a schematic perspective view and a front view of an electrical measurement mechanism suitable for a card socket in the present invention, it can be seen that the electrical measurement mechanism is mainly composed of a standard card transfer device 1, a card socket placing device 2 and an electrical measurement pin transfer device 3, and is linearly arranged according to the order from right to left. The standard card transfer device 1 is composed of a standard card 11, a standard card carrier 12, and a first power driving unit 13 (as shown in fig. 3). The cartridge placement device 2 includes a cartridge 21 and a cartridge carrier 22 (shown in fig. 6). The socket 21 includes a socket body 211 and a plurality of terminals 212 linearly arrayed and fixed along the width direction of the socket body 211, and is integrally positioned and fixed on the socket carrier 22 (as shown in fig. 6 and 7). The electrical measurement pin transfer apparatus 3 includes an electrical measurement pin assembly 31 and a secondary power driving part 32 (as shown in fig. 10). The electrical measurement pin assembly 31 includes pin carriers 311 and electrical measurement pins 312 corresponding in number to the terminals 212. Electrical test pins 312 are inserted through and secured to the pin carrier 311 (as shown in fig. 14). The standard card carrier 12 moves toward or away from the card holder carrier 22 under the driving force of the first power driving part 13 to insert or remove the standard card 11 into or from the card holder body 211, and at the same time, the pin carrier 311 moves toward or away from the card holder carrier 22 under the driving force of the second power driving part 32 to contact or remove the electrical contact pins 312 from the connection terminals 212. In this way, when the electrical conductivity of the card socket 21 needs to be tested, the card socket 21 to be tested is firstly placed in position relative to the card socket carrier 22, and the standard card 11 and the electrical testing pins 312 perform directional displacement motion relative to the card socket 21 to be tested under the action of the first power driving part 13 and the second power driving part 32, respectively, so as to complete the electrical conductivity test of the card socket 21.

The electric measuring mechanism suitable for the card holder has the following beneficial effects: 1) the test efficiency is better, and the test performance is more stable, so that the yield of products is ensured, and the repair cost is reduced; 2) the labor use cost is effectively reduced; 3) the alignment precision of the standard card 11 and the card holder 21 is effectively ensured, the phenomenon of scraping in the insertion process is avoided, and the service life of the standard card 11 is ensured.

The working principle of the electric measuring mechanism suitable for the card holder is as follows: before formal electrical conductivity test is performed on the card socket 21, the card socket 21 to be tested is positioned and fixed on the card socket carrier 22, then the standard card 11 and the electrical testing pins 312 are respectively dragged to approach the card socket 21 to be tested under the driving force of the first power driving part 13 and the second power driving part 32 until the standard card 11 is completely inserted into the card socket 21, and then the electrical testing pins 312 are contacted and conducted with the wiring terminals 212 of the card socket 21, so that the electrical conductivity test of the card socket 21 is completed. Then, the tested card seat 21 is removed, another card seat to be tested is placed again, and the above action process is repeated.

It should be noted that, in the above-mentioned electrical conductivity testing process, the card holder 21 can be clamped and discharged by the manipulator, but it should be noted that, in the equipment debugging stage of the electrical measurement mechanism, the displacement speed of the standard card 11 and the electrical measurement pins 312 needs to be adjusted to ensure the coordination with the material taking and discharging speed of the manipulator.

In order to ensure the higher positioning accuracy of the cartridge 21 compared to the cartridge carrier 22 and the consistency of the relative displacement during the electrical conductivity testing process, a cartridge body placing groove 222 (as shown in fig. 8) matched with the shape of the cartridge body 211 may extend downward from the upper plane of the cartridge carrier 22. And the unilateral clearance between the cassette body 211 and the cassette body placing groove 222 is controlled to be 0.1-0.12 mm.

As can be seen from fig. 6, the cartridge carrier 22 is supported by the cartridge support base 23. And a positioning groove 231 is extended downward from the upper plane of the cartridge support seat 23 and extends in the front-rear direction (as shown in fig. 9). The card seat carrier 22 is clamped and fixed in the positioning groove 231. Thus, after the cassette carrier 22 is mounted on the cassette support base 23, the cassette carrier 22 can be ensured to have higher position accuracy, and the cassette 21 can be ensured to have higher position accuracy.

Further, as shown in fig. 8, a standard card introduction slot 221 may also extend downwardly from the upper plane of the card holder carrier 22. The standard card introduction slot 221 is disposed right to the card socket body placement recess 222 and is communicated with the card socket body placement recess 222, so as to ensure that the standard card 11 has a higher alignment precision with respect to the card socket 21, and is further introduced into the card socket body 211 more smoothly.

In view of reducing the difficulty of manufacturing and processing, reducing the manufacturing cost, and facilitating the subsequent maintenance and replacement of the standard card 11, the standard card carrier 12 is preferably a split structure, which is as follows: the standard card carrier 12 includes a base plate 121, a pressure plate 122, and fasteners 123. The pressing plate 122 covers the upper plane of the base plate 121 and is locked by the fastening member 123. Extending downwardly from the upper surface of the base 121 is a standard card receiving recess 1211 (shown in figure 5).

As is known, various mechanical design structures can be adopted to realize dragging of the standard card carrier 12, but a design structure is proposed herein, which is simple in design structure, easy to manufacture and implement, low in post-maintenance cost, and high in driving stability and precision, that is, the first power driving part 13 is as follows: the first power driving portion 13 includes a standard card support base 131 and a first slide cylinder 132. The first slide cylinder 132 includes a first table 1321 and a first cylinder body 1322 that drives the first table 1321 to perform directional displacement motion in the left-right direction. The standard card support seat 131 is disposed right below the first cylinder body 1322 to support and fix the same. The standard card carrier 12 is detachably fixed to the first table 1321 by means of screws (as shown in fig. 3 and 4).

For the same design purpose, the second power driving part 32 can be implemented by referring to the following scheme, in analogy to the first power driving part 13 described above, specifically as follows: the second power driving part 32 includes an electrical contact pin support base 321 and a second slide cylinder 322. The second sliding table cylinder 322 includes a second working table 3221 and a second cylinder body 3222 configured to drive the second working table 3221 to perform directional displacement motion along the left-right direction. The electrical measurement pin support seat 321 is disposed right below the second cylinder body 3222 to support and fix the same. The pin carrier 311 is dragged by the second table 3221 to make directional displacement motion along the left-right direction (as shown in fig. 10 and 11).

Generally, the second power driving unit 32 is further provided with a force-bearing transition plate 323. The force bearing transition plate 323 is detachably mounted and fixed on the second workbench 3221 by screws, and performs synchronous displacement motion along with the second workbench 3221. The pin carrier 311 is detachably mounted and fixed to the right end of the force-bearing transition plate 323 by means of screws, so as to fix the electrical pin assembly 31 (as shown in fig. 10, 11, 12 and 13).

It should be emphasized here that, as a further optimization of the structure of the electrical measuring mechanism applied to the card socket, as shown in fig. 10, the electrical measuring pin transferring apparatus 3 may be additionally provided with a card socket pressing unit 33 in actual conditions. As a preferred structure of the cartridge pressing unit 33, the cartridge pressing unit includes a pressing member 331, a floating plate 332, a first stopper 333, a second stopper 334, a connecting plate 335, a first guide pin 336, and a second guide pin 337. The pressing member 331 is attached and fixed to the right end portion of the floating plate 332. The number of the connecting plates 335 is 2, and the connecting plates are symmetrically mounted and fixed on the side wall of the electrical measuring pin support base 321 along the front-rear direction. The first limiting seat 333 is arranged right above the force bearing transition plate 323 and is fixedly connected with the connecting plate 335. A first through recess 3331 extends from the left wall of the first position-limiting seat 333 to the right for the floating plate 332 to pass through. And an L-shaped guide slot 3332 (as shown in fig. 16) extending from the front and rear side walls of the first stopper 333 and penetrating the first through groove 3331. The number of the second limiting seats 334 is at least 2, and the second limiting seats are linearly arrayed along the left-right direction and are all fixed on the upper plane of the force bearing transition plate 323. A second through recess 3341 is formed in the left wall of the second retainer 334 for the floating plate 332 to pass through. And inclined guide grooves 3342 (as shown in fig. 17) extending from the front and rear side walls of the second stopper 334 to penetrate the second through recesses 3341. The floating plate 332 is disposed in parallel directly above the force-bearing transition plate 323 while passing through the first and second through recesses 3331 and 3341, and has first and second guide pin mounting holes 3321 and 3322 (see fig. 15) symmetrically formed at front and rear sidewalls thereof. The first guide pin 336 is inserted into and fixed to the first guide pin mounting hole 3321, passes through the L-shaped guide slot 3332, and is capable of freely sliding along the L-shaped guide slot 3332. The second guide pin 337 is inserted into and fixed to the second guide pin mounting hole 3322, passes through the inclined guide slot 3342, and is slidably movable along the inclined guide slot 3342 (see fig. 11, 12, and 13). Thus, before the electrical conductivity test of the card socket 21 and during the actual test process, the pressing member 331 is always pressed on the upper plane of the card socket 21, so as to effectively ensure the positioning accuracy of the card socket 21 in the placement groove 222 of the card socket body, prevent the position deviation phenomenon from occurring due to the instant stress of the electrical contact pin 312 touching the wiring terminal 212 during the process of being inserted into the standard card 11, and further ensure the smooth execution of the electrical conductivity test process of the card socket 21.

The working principle of the clamping seat pressing unit is as follows: before formal electrical conductivity testing is performed on the card socket 21, the card socket 21 to be tested is positioned and fixed on the card socket carrier 22, the standard card 11 is dragged to approach the card socket 21 to be tested under the action of the driving force of the first sliding table cylinder 132 until the standard card 11 is completely inserted into the card socket 21, and synchronously, the second sliding table cylinder 322 acts to drag the electrical measurement pin assembly 31 to approach the card socket 21 to be tested until the electrical measurement pin 312 is contacted and conducted with the connection terminal 212, and meanwhile, the first guide pin 336 and the second guide pin 337 respectively slide along the L-shaped guide slot 3332 and the inclined guide slot 3342 to force the floating plate 332 to drive the pressing member 331 to perform displacement movement to the right, and then perform displacement movement downwards relative to the card socket 21 until the card socket 21 is pressed, and the process of electrical conductivity testing of the card socket 21 is continued to be completed. After the electrical conductivity test of the card seat 21 is completed, the first sliding table cylinder 132 moves reversely to pull the standard card 11 to be released from the card seat 21, and simultaneously, the second sliding table cylinder 322 also moves reversely to pull the electrical measurement pin 312 to be away from the connection terminal 212, and at the same time, the first guide pin 336 and the second guide pin 337 perform adaptive displacement sliding along the L-shaped guide slot 3332 and the inclined guide slot 3342 to force the floating plate 332 to drive the pressing member 331 to perform upward displacement movement opposite to the card seat 21 until completely releasing from the card seat 21, and then perform displacement movement to the right to reserve enough space for the taking and releasing operation of the card seat 21.

It is known that, during the actual operation of the electrical measuring mechanism applied to the card socket, the first guide pin 336 inevitably wears relative to the L-shaped guide slot 3332 and the second guide pin 337 inevitably wears relative to the inclined guide slot 3342, which inevitably results in an increase in the amount of wear, and affects the accuracy of the engagement between the first guide pin 336 and the L-shaped guide slot 3332 and between the second guide pin 337 and the inclined guide slot 3342, thereby affecting the displacement accuracy of the pressing member 331, and further resulting in the occurrence of "pressure loss" caused by the failure of effective pressing or excessive pressing of the card socket 21. In view of this, a wear-resistant coating (not shown) may be provided in both the L-shaped guide groove 3332 and the inclined guide groove 3342. The presence of the wear-resistant coating effectively reduces the relative coefficient of friction between the first guide pin 336 and the L-shaped guide slot 3332 and between the second guide pin 337 and the angled guide slot 3342, and improves the smoothness of the sliding movement of the first guide pin 336 and the second guide pin 337 to some extent.

Fig. 18 is a schematic perspective view of another embodiment of an electrical measuring mechanism suitable for a card socket according to the present invention, which is different from the above embodiment only in that: the electric measurement pin transfer device 3 is additionally provided with a protective shell 34 according to actual conditions. And the protective shell 34 is covered and fixed on the periphery of the second power driving part 32. In this way, on the one hand, dust can be effectively prevented from entering the L-shaped guide groove 3332 and the inclined guide groove 3342, and the smoothness of the sliding movement of the first guide pin 336 and the second guide pin 337 can be ensured; on the other hand, the phenomenon that an operator is pressed by the floating plate 332 can be avoided, and the use safety of the electric measuring mechanism suitable for the clamping seat is ensured.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
