The present invention provides a tape feeder for chip mounters. The tape feeder is constructed so that front and rear locators are restrained by a restraint slot of a cam slider moving horizontally, and bearings of the front and rear locators alternatively execute vertical and horizontal movements while sliding along the restraint slot by a reciprocating motion of a cam slider, thus repeatedly moving a carrier tape backward while locking the carrier tape and moving the carrier tape forward while releasing the carrier tape, therefore allowing the carrier tape to be fed precisely. The tape feeder allows the carrier tape to be fed precisely, and prevents chips from being turned over and removed from the carrier tape when a vinyl cover is discharged, thus minimizing a malfunction of the chip mounter during an operation of the chips and thereby maximizing operational reliability. Further, the tape feeder allows the number of elements to be reduced, in addition to achieving a slim construction. Thus, the number of tape feeders mounted to the chip mounter can be increased.

The invention discloses a slewing bearing comprising a jacket part in connection with a turntable and an embedded part in connection with a frame.

An outer ring of middle roller is mounted between an outer circumferential surface of the radial segment and an inner inside wall of the outer circumference of the jacket part. And the slewing bearing is characterized in that an inner ring of middle roller is disposed between an inner circumferential surface of the radial segment and an inner inside wall of the inner circumference of the jacket part, and the outer ring of middle roller and the inner ring of middle roller are positioned in one plane. The slewing bearing of the invention can reduce radial friction, lower rotary resisting moment, improving transmission uniformity of forces, so that the radial bearing capacity of the slewing bearing can be further enhanced. The invention also discloses a crane containing the above slewing bearing.

The invention discloses a high-density PCIE expansion card main board mounting structure of a server case, the structure including a main board, a plurality of PCIE slots arranged on the main board and spaced apart from each other by a preset distance, and a plurality of PCIE adapter cards inserted in each PCIE slot. At least one side surface of each PCIE adapt card is provided with a plurality ofconnector distributed hierarchically along that height direction of each PCIE adapter card, each connector is used for mate connection with a PCIE board card, and each connector is electrically connected with a goldfinger of the PCIE adapter card. In this way, due to the role of the PCIE adapter card in switching the PCIE board and changing the direction of installation, the PCIE boards can be installed on the PCIE adapter cards along the height direction, thereby utilizing the height space in the server case, and greatly reducing the occupation of the surface area of the main board, so thatmore PCIE boards can be installed on the main boards of the same specification. The invention also discloses a server case, the beneficial effect of which is described above.
