Description

Technical Field

[0001] The utility model relates to the technical field of semiconductors, in particular to the testing and packaging technology of semiconductor components, and specifically is an embedded suction nozzle pressing module. Background Art

[0002] The semiconductor component testing and packaging equipment uses a suction nozzle to pick up IC components for each process test and packaging transfer process. When the suction nozzle picks up the IC components, it is necessary to control the suction nozzle to move vertically up and down through the pressing module.

[0003] The suction nozzle pressing module of the prior art has a beveled cylindrical seat connected to the lower side of the base through a rotating shaft, the bottom of the cylindrical seat is an inclined surface, and the outer edge of the lower inclined surface of the cylindrical seat contacts the vertical moving seat, and a guide rod is provided on the lower side of the vertical moving seat, and a sliding seat is slidably connected to the outer side of the middle of the guide rod, and the sliding seat slides vertically along the sliding groove, and an air nozzle is provided on the lower side of the guide rod, and a spring is provided between the slide block and the vertical moving seat, and the spring is movably sleeved to the outer side of the guide rod. When in use, the cylindrical seat is indirectly rotated through the output shaft of the motor. During the rotation of the cylindrical seat, when the inclined surface of the bottom of the cylindrical seat contacting the upper side of the vertical moving seat is converted from the highest to the lowest, the vertical moving seat is indirectly pressed and driven The suction nozzle moves downward. During this process, the slide slides vertically along the slide groove, the spring contracts, and the suction nozzle is pressed down to perform subsequent IC component adsorption operations. When the bottom slope of the cylindrical seat in contact with the upper side of the vertical movement seat changes from the bottom to the highest, the vertical movement seat is not under pressure at this time, and the suction nozzle moves up and resets through the compression force of the spring. However, during the vertical up and down reciprocating movement of the suction nozzle, when the motor drives the cylindrical seat to rotate too fast, the compression and reset speed of the spring may not keep up with the rotation speed of the motor itself, resulting in the suction nozzle failing to reset in place after being pressed down and moved upward. In addition, when the slider occasionally gets stuck or is slightly inflexible, the suction nozzle may also fail to return to its position, which needs to be improved. Utility Model Content

The lubrication groove 9 is connected with the annular guide groove 63. A cross 10 and an annular seat 14 are respectively provided inside the lubrication groove 9. A blocking seat 13 is provided on the lower side of the cross 10 through a telescopic column 11 and a spring 12. The spring 12 is movably connected to the outer end of the telescopic column 11. A push rod 15 is provided at the lower end of the blocking seat 13. The blocking seat 13 is installed in cooperation with the annular seat 14. A spring 2 17 is provided between the vertical sliding seat 5 and the connecting seat 18. The spring 2 17 is movably connected to the outer side of the lower pressure rod 16. Evenly distributed mounting holes 20 are opened on the upper side of the base 1.

[0024] Among them, the embedded pressing mechanism 6 is arranged between the base 1 and the vertical moving slide 5, and also includes a control switch 2, which is arranged on the outside of the base 1, and the input end of the control switch 2 is electrically connected to the external power supply; the embedded pressing mechanism 6 includes a driving motor 61, a rotating seat 62, an annular guide groove 63 and an embedded slide 64, the embedded slide 64 is arranged at the upper end of the vertical moving slide 5, the lower side of the base 1 is rotatably connected with a rotating shaft through a bearing, the lower end of the rotating shaft is provided with a rotating seat 62, the outer side of the rotating seat 62 is provided with an annular guide groove 63, the embedded slide 64 is slidably connected with the annular guide groove 63, the upper side of the base 1 is provided with a driving motor 61, the input end of the driving motor 61 is electrically connected to the output end of the control switch 2, and the output shaft of the driving motor 61 is fixedly connected to the upper end of the rotating shaft.

[0025] The working principle of the utility model is as follows:

[0026] When the device is used so that the suction nozzle 19 is pressed down to absorb and transport the IC component, the device is first fixed to the specified position with bolts through the mounting hole 20;

[0027] When the suction nozzle 19 is subsequently pressed down, the control switch 2 starts the driving motor 61 so that its output shaft drives the rotating shaft to rotate, and the rotating shaft drives the rotating seat 62 to rotate, and the rotating seat 62 slides through the clamping guide between the annular guide groove 63 and the embedded slide 64, so that the embedded slide 64 drives the vertical slide 5 to slide vertically up and down along the slide rail 4, and the vertical slide 5 indirectly drives the suction nozzle 19 to reciprocate vertically up and down;

[0028] During the downward movement of the suction nozzle 19, the spring 2 17 elastically contracts, and the elastic buffering improves the vertical downward movement stability of the suction nozzle 19. In this process, through the clamping guide sliding between the annular guide groove 63 and the embedded slide 64, even if the output shaft of the driving motor 61 rotates too fast, the suction nozzle 19 will not be unable to keep up with the upward movement recovery speed. The vertical movement slide 5 only needs to overcome the compression force of the spring 2 17 to press the suction nozzle 19 downward. When the vertical movement slide 5 occasionally gets stuck or is slightly inflexible during the sliding process along the slide rail 4, the suction nozzle 19 will not fail to return to its position, thereby improving the control force of the suction nozzle 19 downward, thereby improving the measurement results of the subsequent tested products, and being easy to use. Therefore, by accurately controlling the up and down movement of the suction nozzle 19, the inaccurate upward reset phenomenon after the suction nozzle 19 is pressed down is effectively avoided, and the downward pressure control ability of the suction nozzle 19 is improved;

[0029] At the same time, during the sliding process of the embedded slide 64 along the annular guide groove 63, the embedded slide 64 contacts the rotating ball 7, so that the rotating ball 7 adaptively rotates around the corresponding semicircular groove, thereby reducing the sliding wear between the embedded slide 64 and the annular guide groove 63. At the same time, during the sliding process of the embedded slide 64, when it contacts the push rod 15, the push rod 15 is compressed, the telescopic end of the telescopic column 11 and the spring 12 are contracted, and the blocking seat 13 moves up to release the blocking of the annular seat 14. The lubricating oil in the oil storage tank 8 enters the annular guide groove 63 along the lubrication groove 9 in a small amount, thereby lubricating the sliding between the embedded slide 64 and the annular guide groove 63, further reducing the wear between the two, and thereby improving the service life of the embedded suction nozzle pressing module itself. When the push rod 15 is not in contact with the embedded slide 64, the compression elastic force of the spring 12 makes the blocking seat 13 block the flow of lubricating oil to the annular seat 14, thereby reducing the sliding wear between the embedded slide 64 and the annular guide groove 63 through a variety of protective elements, thereby improving the service life of the suction nozzle pressing module.

[0030] It is worth noting that the driving motor 61 disclosed in the above embodiment can adopt WS-50ZYT78-R, and the control switch 2 is provided with a control button corresponding to the driving motor 61 for controlling its switch.
