The invention discloses a mahjong machine which comprises a base plate, panels, mahjong lifting support plates, a mahjong shuffling plate, mahjong taking and conveying mechanisms and a mahjong pushing and lifting mechanism. Four mahjong taking and conveying mechanisms and four mahjong lifting support plates are installed on a conveying base which is an integrally-formed part provided with four groups of positioning and installing portions. The four groups of positioning and installing portions are centrally symmetrical, each group of positioning and installing portions comprises a conveying and installing portion, a panel installing portion and a guiding shaft seat portion, wherein the conveying and installing portions and the mahjong taking and conveying mechanisms achieve positioning and are locked and fixed through fasteners, and the top ends and panels of the panel installing portions achieve positioning. The guiding shaft seat portions are arranged on the outer sides of the conveying and installing portions, two guiding rods under the mahjong lifting support plates are respectively and vertically inserted into two shaft holes of the guiding shaft seat portions, and the mahjong pushing and lifting mechanism pushes the mahjong lifting support plates to lift. By means of the technical scheme, the panels and the mahjong lifting support plates are positioned on the same part, accordingly the matching requirement of the panels and the mahjong lifting support plates is guaranteed, machine adjustment is decreased, the matching accuracy is improved, and the deformation influence is reduced.

The invention discloses a glue coating crystal solidifying method and a glue coating crystal solidifying system. The method comprises the following steps that A, crystal grains on a wafer disc are picked through a crystal solidifying arm; B, the bottoms of the picked crystal grains are immersed into a glue disc to be coated with glue water to be subjected to gluing treatment; C, the crystal grains subjected to the gluing treatment are bonded and welded on positions requiring crystal solidification on the carrier. One machine and control structure is adopted for crystal picking, and in addition, the glue taking is realized through wafers per se, so adverse phenomena that in the traditional mode, the blind points exist in bonding positions of the crystal grains and the glue points, the bonding surface distribution is nonuniform, the deviation of the crystal grains and the glue drip reset points is greater, the glue form is not full, the absorption firmness is poor, and the like can be avoided. The crystal solidifying method can be realized through adopting the independent system, the problem of collision when two independent mechanisms are used for production in the same station can be completely avoided, the mechanical structure is simplified, the control difficulty is reduced, and meanwhile, the product precision is also improved.

The invention discloses a two-shaft vibration test device with an integrated base, which is provided with a working table, wherein the working table is connected with a moving coil table of a vertical electric vibration table through a first vibration transmitting and decoupling mechanism in the vertical direction, and is connected with a moving coil table of a horizontal electric vibration table through a second vibration transmitting and decoupling mechanism in the horizontal direction. The two-shaft vibration test device is characterized in that the magnetic cylinder part in the vertical electric vibration table body horizontally extends to form a base body, the top surface of the base body is used for bearing the horizontal electric vibration table, and the table body of the horizontal electric vibration table is arranged on the top surface of the base body. When the device is mounted, the base body, namely the magnetic cylinder part of the vertical electric vibration table is directly is connected with a foundation or contacted with the foundation through a vibration damping device; and the height difference from the top surface of the base to the working table surface can be calculated during the designing, the mounting height of the horizontal electric vibration table can be determined through the height difference, and the difficulty for mounting and debugging is greatly reduced.

The invention discloses a method for determining dip angles of all rings of sub-mirrors of a Fresnel heliostat. The method includes the following steps that (1) all sub-mirrors of the Fresnel heliostat are set to be coplanar, a sunlight incidence angle which is not equal to zero is given, a certain ring of sub-mirrors of the Fresnel heliostat is selected, and light spots of the ring of sub-mirrors are a large hollow ellipse; (2) a synchronization dip angle adjusting mechanism is used for enabling the ring of sub-mirrors to be inclined inwards gradually, the light spots are gradually decreased until the light spots are gathered into a narrow ellipse with a minimum short shaft, and reflection light in the short shaft direction is gathered to be superlative; (3) the sub-mirrors are inclined inwards continuously, reflection light in the long shaft direction is continuously gathered, light in the short shaft direction starts to be scattered, the ellipse becomes to turn to a circle until the sizes of the long and short shafts are the same, and setting of the dip angles of the ring of sub-mirrors is set; and (4) the dip angles of all rings of sub-mirrors are sequentially set, and a minimum concentrated light spot is formed. By means of the method, the manufacturing cost of the heliostat is greatly reduced; and the condensing function can be well achieved.
