Abstract
Description
Technical Field
[0001] The utility model relates to a rotation positioning and reversing mechanism device for an integrated circuit chip. Background Art
[0002] After production, integrated circuit chips need to be tested for their high-temperature resistance. This means heating the integrated circuit chips to a certain temperature and testing whether some of the properties of the integrated circuit chips still meet their working performance requirements.
[0003] To save space, integrated circuit chip testing currently utilizes a turret-style test system. This involves the IC chip being placed into a test module using a suction cup, which then rotates the chip. After testing, the chip is removed by the suction cup and then rotated into the next test module. However, before the IC chip enters the test module, the orientation of the chip's pins differs from that on the test module. Therefore, the IC chip must undergo a repositioning process before entering the test module. Utility Model Content

DETAILED DESCRIPTION
[0024] To make the above features and advantages of the present invention more clearly understood, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.
[0025] refer to Figures 1 to 5
[0026] A rotational positioning and reversing mechanism device for an integrated circuit chip comprises a base assembly 100 for detachably connecting to a frame, a sleeve 200 which is vertically rotatably connected to the upper front portion of the base assembly and is driven to rotate by a driving mechanism, a chip positioning seat 300 is mounted on the upper end of the sleeve, and a clamping mechanism for clamping the integrated circuit chip is provided on the chip positioning seat.
[0027] In this embodiment, in order to drive the sleeve to rotate, the driving mechanism includes a synchronous pulley 201 fixed on the sleeve, a fixed seat 202 is installed on the front upper part of the base assembly, the sleeve is rotatably connected to the fixed seat, and a vertical motor 203 is installed on the fixed seat. The output shaft of the vertical motor is installed with a synchronous pulley and is connected to the synchronous pulley on the sleeve through a synchronous belt, thereby driving the chip positioning seat to rotate through the sleeve to adjust the position of the chip.
[0028] In this embodiment, to achieve chip clamping and positioning, the clamping mechanism includes at least two vertical clamping rods 310, and more specifically, four vertical clamping rods. These rods are rotatably connected to the side of the chip positioning seat at intervals along the circumference of the axis. Clamping blocks 320 for clamping the integrated circuit chip are fixed to the upper ends of the vertical clamping rods. The vertical clamping rods are driven by a lifting mechanism to open and close the clamping blocks, completing the chip clamping and release operations.
[0029] In this embodiment, in order to realize the opening and closing action of the clamping block, the lifting mechanism includes a lifting rod 330 that vertically passes through the sleeve and is driven to rise and fall by a cam mechanism. The upper end of the lifting rod extends into the lifting cavity 301 set in the chip positioning seat. The upper part of the lifting rod is provided with a radial flange 331, and the top of the radial flange is provided with an annular slope. The upper part of the vertical clamping rod is provided with a driving part located in the lifting cavity and on the upper side of the lifting rod. The driving part is installed with a roller 311, and a spring 312 is provided between the lower part of the vertical clamping rod and the chip positioning seat. When the lifting rod rises, the annular slope cooperates with the roller to push the upper part of the vertical clamping rod outward, so that the four clamping blocks are simultaneously expanded outward; when the lifting rod descends, the upper part of the vertical clamping rod moves toward each other due to the action of the spring to complete the clamping action.
[0030] In this embodiment, the cam mechanism includes a horizontal motor 204 mounted on a fixed base, an eccentric cam 205 mounted on the output shaft of the horizontal motor, and the eccentric cam abuts the lower end of the lifting rod. The horizontal motor drives the eccentric cam to rotate, thereby driving the lifting rod to rise and fall.
[0031] In this embodiment, to better maintain the chip in the desired position after rotation, the front and rear sides of the chip positioning seat are each provided with a fixing rod 206 mounted on a fixing seat. These two fixing rods are equipped with matching infrared sensors 207 (an infrared transmitter and an infrared receiver). A support block 302 for placing the integrated circuit chip is located on top of the chip positioning seat. The upper portion of the positioning block is provided with a clamping protrusion 321 that curves toward the upper side of the support block. The working surface of the clamping protrusion is provided with several vertical grooves. The clamping protrusion is also provided with an avoidance groove 322 for sensing the passage of light. When the infrared sensor can sense light, it indicates that the sleeve has been rotated into place and no chip is placed on the support block.
[0032] In this embodiment, in order to better install the fixing seat, the base assembly includes a guide rail 110 and a socket 120 detachably connected to the guide rail, and the socket is equipped with a connecting seat 130 that can be adjusted for left and right deflection, and the front of the connecting seat is provided with a fixing seat 202 for installing the sleeve.
[0033] In this embodiment, the front side of the guide rail is provided with an inverted L-shaped block 111, which is located on the upper side of the socket and extends from the horizontal plate to the rear. The guide rail is provided with a hook 112, and the socket is provided with a longitudinal slot 121 that cooperates with the guide rail. The socket is mounted with a lock 122 that passes through the socket and cooperates with the hook. The rear end of the socket is threaded with an adjustment bolt 123 for abutting the rear end of the guide rail. The lock and hook connect to achieve a quick connection between the socket and the guide rail; the adjustment bolt adjusts the distance between the socket and the rear end of the guide rail, thereby adjusting the tension of the lock.
[0034] In this embodiment, to better adjust the position of the lock, the socket is equipped with a fixing block 124. Long slots 125 are longitudinally provided on both sides of the fixing block and are connected and locked to the socket via screws. The lock is installed obliquely on the fixing block. The socket is provided with a notch 126 for the lock to pass through, and the connecting socket is provided with an escape groove 135 for the buckle to be exposed. The longitudinal position of the socket can be adjusted by adjusting the position of the lock and the position of the adjustment bolt.
[0035] In this embodiment, a hinge column 127 is vertically installed on the upper side surface of the rear part of the socket, and a rotatable eccentric column 128 is installed on the upper side surface of the front part of the socket. The lower end of the eccentric column has an eccentric shaft rotatably connected to the socket, and the upper end of the eccentric column has an inner hexagonal slot. The rear part of the connecting seat is rotatably connected to the hinge column, and a long slot 131 is provided on the connecting seat to cooperate with the eccentric column, so that the left and right deflection adjustment of the connecting seat is completed by rotating the eccentric column.
[0036] In this embodiment, in order to lock the connecting seat with the plug-in seat after adjusting the deflection angle, a first transverse long groove 132 is provided at the rear of the connecting seat, and second transverse long grooves 133 are provided on both sides of the front of the connecting seat. Locking bolts 134 that are threadedly connected to the plug-in seat are provided in the first transverse long groove and the second transverse long groove.
[0037] During operation, the vertical motor drives the sleeve to rotate the chip positioning seat through the synchronous belt. When the two infrared sensors are connected, the vertical motor stops rotating; the cam mechanism drives the lifting rod to rise, allowing the clamping mechanism to open; the chip is sucked up by the suction cup and placed on the support block, and then the lifting rod descends, and the clamping block clamps the chip; at this time, the two infrared sensors cannot be connected; the vertical motor drives the chip positioning seat to rotate 90°, and the cam mechanism drives the lifting rod to rise, allowing the clamping mechanism to open, and the chip is sucked up and moved to the test module through the suction cup; at this time, the two infrared sensors are connected, and the vertical motor drives the chip positioning seat to rotate 90° in the opposite direction to take over the next chip.
[0038] If the terms "first" and "second" are used in the present invention to limit components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of description to distinguish the components. Unless otherwise stated, the above terms have no special meaning.
[0039] If the present invention discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integral molding using a casting process) (except where it is obviously not possible to use an integrated molding process).
[0040] In addition, unless otherwise stated, the terms used in any technical solution disclosed in the above-mentioned utility model to express positional relationships or shapes include states or shapes that are approximate, similar or close thereto.
[0041] Any component provided by the present invention may be assembled from a plurality of separate components, or may be a separate component manufactured by an integral forming process.
[0042] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
