Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the invention and therefore show only the structures which are relevant to the invention.
As shown in fig. 1 to 9, the present embodiment provides a chip detection system, including: the detection box 1 and the box cover 2 are oppositely arranged, the detection box 1 is suitable for detecting whether the chip is qualified, and the box cover 2 is suitable for pressing the chip on the detection box 1. Specifically, the detection box 1 can be mounted on a circuit board, a detection circuit is arranged on the circuit board, a notch is formed in the detection box 1, a detection plane is arranged in the notch, the detection plane is electrically connected with the detection circuit, and a plurality of detection units are arranged on the detection plane. The shape of the notch corresponds to the chip so that the chip can be inserted into the notch and limited by the side wall of the notch. One side of the box cover 2 is hinged with the detection box 1, and after the chip is placed in the notch, the box cover 2 can rotate around the intersection point, so that the box cover 2 seals the notch of the detection box 1.
In order to ensure that the box cover 2 and the detection box 1 stably keep a closed state when detecting the chip, in this embodiment, a clamping groove 11 is formed in the other side of the detection box 1, a limiting clamping plate 21 is arranged on the corresponding side of the box cover 2, after the box cover 2 and the detection box 1 are closed, an operator can manually control the limiting clamping plate 21 to be inserted into the clamping groove 11, so that the limiting clamping plate 21 is clamped with the detection box 1, and the box cover 2 is limited. As an alternative embodiment, the middle part of the limiting clamping plate 21 is hinged with the box cover 2, and meanwhile, a clamping hook 22 is arranged at the bottom of the limiting clamping plate 21, and the clamping hook 22 corresponds to the clamping groove 11. After the notch of the detection box 1 is closed by the box cover 2, an operator can operate the limiting clamping plate 21 to rotate around the hinge joint, so that the clamping hook 22 is inserted into the clamping groove 11.
In addition, in order to further ensure that the chip is closely laminated with detecting element, be provided with hold-down mechanism 3 on lid 2, hold-down mechanism 3 is suitable for along length direction flexible, and after lid 2 seals the notch, hold-down mechanism 3 can be along vertical direction extension and insert inside the notch, until compress tightly the chip on detecting the plane to make chip and detecting element fully contact, and form stable electricity and connect, and then detect the chip.
The structure of the pressing mechanism 3 is specifically described below, the pressing mechanism 3 includes a knob 31, a pressing table 32 and a lifting rod 33, the knob 31 is rotationally connected with the box cover 2, the lifting rod 33 is coaxially arranged with the knob 31, and the pressing table 32 is in transmission connection with the lifting rod 33. The knob 31 is arranged at the top of the box cover 2, and an operator can drive the knob 31 to rotate so that the knob 31 drives the lifting rod 33 to rotate. In this embodiment, as an alternative, the lifting rod 33 is inserted into the pressing table 32, and the lifting rod 33 is in threaded connection with the pressing table 32, in this way, since the inner wall of the box cover 2 limits the pressing table 32, when the lifting rod 33 rotates relative to the pressing table 32, the pressing table 32 is driven to lift by the threads, and after the box cover 2 closes the notch, the pressing table 32 descends, so that the chip can be pressed on the detection unit. In addition, since the notch corresponds to the chip, it is inconvenient for the operator to take out the chip from the notch after the detection is completed, so in this embodiment, the bottom of the pressing table 32 is provided with the material taking groove 321, the material taking groove 321 is suitable for mounting the material taking sheet, the material taking sheet may be a viscous sheet, such as a solid glue, to attach the material taking sheet in the material taking groove 321, and squeeze the chip, after the detection is completed, the material taking sheet can take the chip out of the notch by adhering, at this time, the operator tears the material taking sheet from the material taking groove 321, and then separates the chip from the material taking sheet. At the next cycle, a new take-off tab is replaced in take-off slot 321 and the above operation is repeated.
It should be noted that, the existing chip detection system has strict requirements for operation procedures and steps, for example, a plurality of detection units are arranged in the detection mechanism, the chip is connected with the detection units to realize the connection of the chip, so as to realize the detection of the chip, and when the chip is installed, a limit mechanism is needed to compress the chip and the detection units to ensure reliable connection, but when the limit mechanism does not have the chip in the detection mechanism, if an operator misoperation occurs in the detection mechanism, the limit mechanism is likely to compress the detection units, so that the detection units are crushed, and then the chip detection system is damaged. Therefore, in this embodiment, the box cover 2 is circumferentially provided with a plurality of anti-collision mechanisms 4, and the anti-collision mechanisms 4 are located at the bottom of the box cover 2, and preferably, the anti-collision mechanisms 4 have four. One side of the anti-collision mechanism 4 is abutted against the pressing mechanism 3, namely, the anti-collision mechanism 4 can limit the pressing table 32, so that the pressing table 32 is kept in a righted state. The anti-collision mechanism 4 is suitable for extending and contracting along the width direction, and the extending and contracting direction of the anti-collision mechanism 4 is perpendicular to the extending and contracting direction of the pressing mechanism 3. Specifically, taking the case that the case cover 2 is in a closed state as an example, the pressing table 32 can be lifted in the vertical direction, the anti-collision mechanism 4 stretches in the horizontal direction, and the anti-collision mechanism 4 can extend inwards to be located below the pressing table 32. Through the above arrangement, when the box cover 2 is opened, if the operator misoperates, the pressing table 32 is unfolded outwards, in this process, the pressing table 32 pushes the anti-collision mechanisms 4 to be unfolded outwards, i.e. away from one side of the pressing table 32, and at this time, the width of the unfolded anti-collision mechanism 4 is greater than the width of the notch, i.e. the anti-collision mechanism 4 blocks between the box cover 2 and the detection box 1, and further blocks the box cover 2 and the detection box 1 to be closed. In this way, it is possible to avoid that the pressing table 32 is unfolded and pressed into the test cassette 1 in a state without a chip, and thus to avoid damaging the test unit.
On the other hand, in the process of detecting the chip, when the box cover 2 is closed, the pressing table 32 is unfolded outwards, the pressing table 32 pushes each anti-collision mechanism 4, and the outer side of each anti-collision mechanism 4 is abutted against the inner wall of the detection box 1, so that the anti-collision mechanism 4 is contracted until the pressing mechanism 3 passes over the anti-collision mechanism 4.
To achieve the above effect, in this embodiment, the anti-collision mechanism 4 includes a positioning frame 41 and a telescopic assembly 42 disposed inside the positioning frame 41. The positioning frame 41 is connected with the inner wall of the box cover 2, and the positioning frame 41 is used for supporting the telescopic component 42. One end of the positioning frame 41 far away from the inner wall of the box cover 2 is abutted against the pressing table 32, the telescopic component 42 is elastically connected with the positioning frame 41, and the telescopic component 42 is suitable for being telescopic along the length direction. One end of the telescopic component 42 extends to the lower part of the pressing table 32 and abuts against the bottom of the pressing table 32. Through the arrangement, when an operator misoperates, the box cover 2 is opened, the pressing table 32 is unfolded outwards, the pressing table 32 pushes the telescopic component 42 to slide outwards, so that the other end of the telescopic component 42 protrudes out of the outer side wall of the positioning frame 41, namely protrudes out of the inner wall of the notch of the detection box 1, and at the moment, the telescopic component 42 is blocked between the box cover 2 and the detection box 1 to block the detection box 1 and the box cover 2 from being closed. When the box cover 2 is closed, the pressing table 32 is unfolded outwards, the pressing table 32 pushes the telescopic assembly 42 to slide outwards, so that the other end of the telescopic assembly 42 is abutted against the inner wall of the detection box 1, and cannot slide outwards continuously, at the moment, the telescopic assembly 42 is contracted until the telescopic assembly is completely retracted into the positioning frame 41, at the moment, the telescopic assembly 42 does not block the pressing table 32 any more, and the pressing table 32 passes over the telescopic assembly 42 and continuously presses a chip downwards.
In order to achieve the above effect, the inner side of the positioning frame 41 is provided with a telescopic slot 411, and the telescopic assembly 42 is disposed in the telescopic slot 411. The mirror images on two sides of the telescopic slot 411 are provided with guide slots 412, two sides of the telescopic component 42 are provided with guide blocks 43, the guide blocks 43 correspond to the guide slots 412, the guide blocks 43 are slidably arranged in the guide slots 412, and the guide blocks 43 slide in the guide slots 412 to realize the effect that the whole telescopic component 42 slides along the guide slots 412. A guide spring 44 is further disposed in the guide groove 412, one end of the guide spring 44 is connected to the guide groove 412, and the other end is connected to the guide block 43. Through the arrangement, when the compression table 32 extrudes the telescopic assembly 42, the telescopic assembly 42 can be driven to integrally slide along the guide groove 412 through the guide block 43, and meanwhile, after the telescopic assembly 42 is separated from the compression table 32, the guide spring 44 can drive the guide block 43 to drive the telescopic assembly 42 to integrally reset.
In order to realize the expansion and contraction of the expansion and contraction component 42 and achieve the effect of length change, in this embodiment, the expansion and contraction component 42 includes a limiting block 421 and an adjusting block 422, a movable groove 423 is formed on the outer side wall of the adjusting block 422, the limiting block 421 is sleeved in the movable groove 423, and the limiting block 421 is elastically connected with the adjusting block 422. The adjusting block 422 is arranged inside the positioning frame 41. The movable groove 423 is internally provided with a movable spring 424, one end of the movable spring 424 is connected with the inner bottom wall of the movable groove 423, and the other end is connected with the limiting block 421. The adjusting block 422 and the limiting block 421 are connected through the movable spring 424, and the elastic coefficient of the movable spring 424 is larger than that of the guide spring 44, i.e. the length change of the movable spring 424 is smaller than that of the guide spring 44 under the same pressure. Through the arrangement, when the pressing table 32 presses the adjusting block 422, the adjusting block 422 transmits the pressing force to the guide spring 44 of the movable spring 424, at this time, the length change of the guide spring 44 is larger, and the length change of the adjusting block 422 and the limiting block 421 is smaller, namely, the state that the adjusting block 422 and the limiting block 421 integrally slide outwards is presented, and if the process occurs in the state that the box cover 2 is opened, at this time, the adjusting block 422 and the limiting block 421 integrally slide outwards to the outer side of the notch, so that the box cover 2 and the detection box 1 are blocked by the adjusting block 422 and the limiting block 421; if this process occurs in the state that the lid 2 is closed, after the adjusting block 422 and the limiting block 421 integrally slide outwards for a short distance, the limiting block 421 abuts against the side wall of the notch, so that the outward sliding cannot be continued, at this time, the movable spring 424 is compressed, the distance between the limiting block 421 and the adjusting block 422 is gradually reduced, so that the limiting block 421 and the adjusting block 422 exhibit the effect of shrinkage, until the adjusting block 422 is shrunk to the compressing table 32 to be separated, the compressing table 32 can pass through the adjusting block 422, and the chip is continuously extruded downwards.
In order to facilitate the compression table 32 to compress and drive the adjusting block 422 to shrink, in this embodiment, an adjusting inclined plane 425 is formed on the inner side wall of the adjusting block 422, and the adjusting inclined plane 425 is disposed towards the compression mechanism 3. In this way, when the pressing stage 32 presses the adjustment block 422 in a direction perpendicular to the adjustment block 422, the adjustment block 422 is driven to slide outward by the adjustment slope 425.
In addition, after taking out the tablet chip from the notch, in order to make things convenient for the operator to take out the tablet from taking out in the groove 321 down, the wide groove 413 has still been seted up to the mirror image on the inside wall of locating rack 41, widen the groove 413 and be located guide slot 412 is inboard, widen the groove 413 with guide slot 412 intercommunication, just guide slot 412 with be provided with guide inclined plane 414 between the groove 413. The width of the widening slot 413 is greater than the width of the guide block 43. After the chip is adhered to the material taking piece and leaves the notch, an operator can press the limiting block 421 from the outer side, so that the limiting block 421 slides inwards, then the adjusting block 422 slides inwards through the movable spring 424, the guide block 43 slides onto the guide inclined plane 414 along the guide groove 412, the outer side end of the limiting block 421 swings downwards, so that the inner side end of the limiting block 421 drives the adjusting block 422 to tilt upwards, at the moment, the tip of the adjusting inclined plane 425 faces the material taking piece in the material taking groove 321 of the widening groove 413, and the operator continuously drives the guide block 43 to slide to the top of the widening groove 413 along the guide inclined plane 414, so that the adjusting inclined plane 425 of the adjusting block 422 is shoveled between the material taking groove 321 and the material taking piece, and the material taking piece is shoveled.
In order to facilitate the adjustment of the inclined plane 425 shoveling into the top of the material taking sheet, in this embodiment, the material taking groove 321 is circumferentially provided with a plurality of matching grooves 34, and one positioning frame 41 corresponds to one matching groove 34.
