Detailed Description
In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "front", "rear", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.
In order to facilitate the understanding of the technical solution disclosed in the present invention by those skilled in the art, the following description will further explain the present invention in detail with reference to specific embodiments, and fig. 1 and 2 respectively show a perspective schematic view and a front view of an electrical measurement mechanism suitable for a card socket in the present invention, where the electrical measurement mechanism is mainly composed of a standard card transferring device 1, a card socket placing device 2 and an electrical measurement pin transferring device 3, and are sequentially and linearly arranged along a right-to-left direction. The standard card transfer apparatus 1 is constituted by a standard card 11, a standard card carrier 12, and a first power drive section 13 (as shown in fig. 3). The cartridge placement device 2 includes a cartridge 21 and a cartridge carrier 22 (as shown in fig. 6). The card holder 21 includes a card holder body 211 and a plurality of terminals 212 linearly arrayed and fixed along the width direction of the card holder body 211, and is integrally positioned and fixed on the card holder carrier 22 (as shown in fig. 6 and 7). The electrical test pin transfer apparatus 3 includes an electrical test pin assembly 31 and a second power drive section 32 (as shown in fig. 10). The electrical test pin assembly 31 includes a pin carrier 311 and electrical test pins 312 corresponding to the number of terminals 212. The electrical test pins 312 are inserted through and fixed to the pin carrier 311 (as shown in fig. 14). The standard card carrier 12 moves in opposite directions or in opposite directions relative to the card holder carrier 22 under the driving force of the first power driving part 13 so as to insert or release the standard card 11 into or from the card holder body 211, and at the same time, the pin carrier 311 moves in opposite directions or in opposite directions relative to the card holder carrier 22 under the driving force of the second power driving part 32 so as to contact or release the electrical measurement pins 312 with the connection terminals 212. In this way, when the electrical conductivity of the card holder 21 needs to be tested, the card holder 21 to be tested is first placed in place relative to the card holder carrier 22, and the standard card 11 and the electrical test pin 312 respectively perform directional displacement movement relative to the card holder 21 to be tested under the action of the first power driving portion 13 and the second power driving portion 32, so as to complete the electrical conductivity test of the card holder 21.
Above-mentioned electricity survey mechanism suitable for cassette has following beneficial effect: 1) The test device has good test efficiency and more stable test performance, thereby ensuring the yield of products and further reducing the repair cost; 2) The manual use cost is effectively reduced; 3) The alignment precision of the standard card 11 and the card seat 21 is effectively ensured, the scratch phenomenon in the inserting process is avoided, and the service life of the standard card 11 is ensured.
The working principle of the electrical measuring mechanism suitable for the clamping seat is approximately as follows: before the formal electrical conductivity test is performed on the card holder 21, the card holder 21 to be tested is first positioned and fixed on the card holder carrier 22, then the standard card 11 and the electrical test pin 312 are respectively dragged under the driving force of the first power driving part 13 and the second power driving part 32 to approach the card holder 21 to be tested until the standard card 11 is completely inserted into the card holder 21, and then the electrical test pin 312 is contacted and conducted with the connection terminal 212 of the card holder 21, so that the electrical conductivity test of the card holder 21 is completed. Then, the tested card holder 21 is removed, another card holder to be tested is put in again, and the above action process is circulated.
It should be noted that, in the above-mentioned electrical conductivity test process, the clamping and discharging of the card holder 21 may be performed by means of a manipulator, but it should be noted that, in the equipment debugging stage of the electrical testing mechanism, the displacement speeds of the standard card 11 and the electrical testing pin 312 need to be adjusted to ensure coordination with the feeding and discharging speed of the manipulator.
In order to ensure the consistency of the relative displacement of the cartridge 21 in the electrical conductivity testing process with higher positioning accuracy than the cartridge carrier 22, a cartridge body placement groove 222 (as shown in fig. 8) adapted to the shape of the cartridge body 211 may also be extended downward from the upper plane of the cartridge carrier 22. And the single-side gap between the cartridge body 211 and the cartridge body placement groove 222 is controlled to be 0.1-0.12mm.
In addition, as can be seen from fig. 6, the cartridge carrier 22 is supported by a cartridge support 23. And a positioning groove 231 is extended downwards from the upper plane of the cartridge supporting seat 23, and runs along the front-rear direction (as shown in fig. 9). The cartridge carrier 22 is clamped and fixed in the positioning groove 231. Thus, after the cartridge carrier 22 is mounted on the cartridge support 23, the cartridge carrier 22 can be ensured to have high position accuracy, and the cartridge 21 can be ensured to have high position accuracy.
Furthermore, as shown in fig. 8, a standard card guide slot 221 may also extend downward from the upper plane of the cartridge carrier 22. The standard card guiding groove 221 is disposed on the right side of the card holder body placement groove 222 and communicates with the card holder body placement groove 222, so as to ensure that the standard card 11 has a higher alignment accuracy with respect to the card holder 21, and is further smoothly guided into the card holder body 211.
In order to reduce the difficulty of manufacturing and processing, reduce the manufacturing cost and facilitate the subsequent maintenance and replacement of the standard card 11, the standard card carrier 12 is preferably a split structure, and is specifically as follows: the standard card carrier 12 includes a base plate 121, a platen 122, and fasteners 123. The pressing plate 122 is covered on the upper plane of the base plate 121, and is locked by the fastener 123. A standard card placement groove 1211 (shown in fig. 5) extends downward from the upper plane of the base plate 121.
As is known, various mechanical design structures may be adopted to realize the dragging of the standard card carrier 12, however, a design structure is recommended herein, which is simple, beneficial to manufacturing and implementation, low in post maintenance cost, and high in driving stability and accuracy, namely the first power driving portion 13, specifically as follows: the first power driving part 13 includes a standard card support base 131 and a first slide table 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 movement in the left-right direction. The standard card support 131 is disposed directly under the first cylinder body 1322 to support and fix the same. The standard card carrier 12 is removably secured to the first table 1321 described above (as shown in fig. 3 and 4) by means of screws.
For the same design purpose, the second power driving part 32 can be performed by analogy to the first power driving part 13 described above with reference to the following scheme, in particular: the second power driving part 32 comprises an electrical measurement pin supporting seat 321 and a second sliding table cylinder 322. The second slide table cylinder 322 includes a second stage 3221 and a second cylinder body 3222 for driving the second stage 3221 to perform directional displacement movement in the left-right direction. The electrical measurement pin support 321 is disposed directly under the second cylinder body 3222 to support and fix it. The pin carrier 311 is dragged by the second workbench 3221 to perform directional displacement motion along the left-right direction (as shown in fig. 10 and 11).
In general, the second power driving unit 32 is further provided with a force-receiving transition plate 323. The force-bearing transition plate 323 is detachably attached to the second table 3221 by means of screws, and performs synchronous displacement movement following the second table 3221. The pin carrier 311 is detachably mounted by means of screws, and fixes Yu Cheng the right end of the force transition plate 323, thereby achieving the fixation of the electrical test pin assembly 31 (as shown in fig. 10, 11, 12, 13).
It should be emphasized here that, as a further optimization of the structure of the electrical measuring mechanism suitable for the cartridge, as shown in fig. 10, the electrical measuring pin transfer apparatus 3 may be actually provided with a cartridge pressing unit 33. As a preferable structure of the above-described cartridge pressing unit 33, it includes a pressing member 331, a floating plate 332, a first stopper 333, a second stopper 334, a connection plate 335, a first guide pin 336, and a second guide pin 337. The pressing member 331 is mounted and fixed to the right end portion of the floating plate 332. The number of the connecting plates 335 is 2, and they are symmetrically installed and fixed on the side wall of the electrical test pin support 321 along the front-rear direction. The first limiting seat 333 is disposed directly above the force-bearing transition plate 323 and is fixedly connected with the connecting plate 335. A first through groove 3331 extends from the left side wall of the first limiting seat 333 to the right for passing through the floating plate 332. And the front and rear side walls of the first limiting seat 333 are extended with L-shaped guide grooves 3332 (as shown in fig. 16) which are communicated with the first through grooves 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 fixed on the upper plane of the bearing transition plate 323. A second through groove 3341 extends from the left side wall of the second limiting seat 334 to the right, and is also used for passing through the floating plate 332. And inclined guide grooves 3342 (shown in fig. 17) penetrating the second penetrating grooves 3341 are extended from the front and rear sidewalls of the second limiting base 334 relatively low. The floating plate 332 is disposed in parallel directly above the force-bearing transition plate 323 and passes through the first and second through grooves 3331 and 3341, and is symmetrically provided with first and second guide pin mounting holes 3321 and 3322 on front and rear side walls thereof (as shown in fig. 15). The first guide pin 336 is inserted into and fixed to the first guide pin mounting hole 3321, passes through the L-shaped guide groove 3332, and can slide freely along the L-shaped guide groove 3332. The second guide pin 337 is inserted into the second guide pin mounting hole 3322, passes through the inclined guide slot 3342, and can slide freely along the inclined guide slot 3342 (as shown in fig. 11, 12, and 13). In this way, before the electrical conductivity test is performed on the card holder 21 and during the actual test process, the pressing member 331 is always pressed against the upper plane of the card holder 21, so as to effectively ensure the positioning accuracy of the card holder 21 in the card holder body placement groove 222, prevent the position dislocation phenomenon caused by the stress in the process of being inserted into the standard card 11 and the moment when the electrical measurement pin 312 touches the connection terminal 212, and further ensure the smooth execution of the electrical conductivity test process of the card holder 21.
The working principle of the clamping seat pressing unit is approximately as follows: before the card seat 21 is subjected to the formal conductivity test, the card seat 21 to be tested is positioned and fixed on the card seat carrier 22, the standard card 11 is dragged to approach the card seat 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 seat 21, synchronously, the second sliding table cylinder 322 acts to drag the electrical contact pin assembly 31 to approach the card seat 21 to be tested until the electrical contact pin 312 is contacted and conducted with the wiring terminal 212, meanwhile, the first guide pin 336 and the second guide pin 337 slide along the L-shaped guide groove 3332 and the inclined guide groove 3342 respectively to force the floating plate 332 to drive the pressing member 331 to move rightwards, and then move downwards towards the card seat 21 until the electrical conductivity test process of the card seat 21 is completed. After the card holder 21 completes the electrical conductivity test, the first sliding table cylinder 132 moves reversely to drag the standard card 11 to be separated from the card holder 21, and synchronously, the second sliding table cylinder 322 also moves reversely to drag the electrical measurement pins 312 away from the connection terminals 212, meanwhile, the first guide pins 336 and the second guide pins 337 slide in an adaptive displacement manner along the L-shaped guide grooves 3332 and the inclined guide grooves 3342 to force the floating plate 332 to drive the pressing member 331 to move upwards and away from the card holder 21, and then move right and left to reserve enough space for the taking and placing operations of the card holder 21.
It is known that, in the actual operation of the electrical measurement mechanism suitable for the cartridge, the first guide pin 336 inevitably generates a wear phenomenon with respect to the L-shaped guide groove 3332 and the second guide pin 337 with respect to the inclined guide groove 3342, which inevitably leads to an increase in wear amount, and affects the precision of the first guide pin 336 and the L-shaped guide groove 3332 and the second guide pin 337 and the inclined guide groove 3342, thereby affecting the displacement precision of the pressing member 331, and further leading to the occurrence of a "pressure loss" phenomenon caused by the failure of the cartridge 21 to be effectively pressed or the excessive pressing force. 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 shows a schematic perspective view of another embodiment of an electrical testing mechanism for a cartridge according to the present invention, which is different from the above embodiment only in that: the electrical test 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 further smoothness of sliding movement of the first guide pin 336 and the second guide pin 337 can be ensured; on the other hand, the phenomenon that the operator is crushed by the floating plate 332 can be avoided, and the safety of the electrical measuring mechanism suitable for the clamping seat in use is ensured.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. 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.
