Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
Referring to fig. 1-3, a material exchanging device with dual temperature zones for avoiding temperature crosstalk; comprises a sleeve 4-1, a driving motor 4-2, an electric ejector rod consisting of a push rod 4-3, a spring 4-4, a tray 4-5, a sealing element 4-6, a spring baffle 4-7 and a driving motor 4-2; the spring baffle 4-7 is fixed on the sleeve 4-1.
The push rod 4-3 is inserted in the sleeve 4-1;
the driving motor 4-2 drives the push rod 4-3 to extend and retract in the sleeve 4-1;
the tray 4-5 is fixedly arranged at the free end of the push rod 4-3;
the material taking and placing opening 1-1 arranged on the refrigerated storage cabinet is in a circular truncated cone shape;
the sealing element 4-6 is in a round table shape, is movably sleeved on the push rod 4-3, and has an upper bottom surface with a diameter smaller than that of the lower bottom surface of the material taking and placing opening and a lower bottom surface with a diameter larger than that of the upper bottom surface of the material taking and placing opening; a spring 4-4 is sleeved on the push rod 4-3, one end of the spring is propped against the sealing element 4-6, and the other end of the spring is propped against a spring baffle 4-7 fixed on the sleeve 4-1; in an initial state, the sealing elements 4-6 are clamped in the material taking and placing opening 1-1 under the elastic force of the spring, and the inside and the outside of the cabinet body 1 are sealed.
As shown in fig. 4, in a default state, the material exchanging device of the dual-temperature zone for avoiding temperature crosstalk is in the position shown in fig. 4, and the sealing element 4-6 seals the material taking and placing opening; the tray 4-5 is positioned outside the double-temperature-zone partition board 1, and solder paste required to be stored in the refrigeration storage cabinet can be placed on the tray 4-5. Please note that, since there is no fixed adhesion between the tray 4-5 and the sealing member 4-6, if the pushing rod 4-3 is pushed upwards, the tray 4-5 can be higher than the partition board 1 of the dual temperature zone by a certain distance, and the sealing member 4-6 is sealed in the material taking and placing opening 1-1 due to the fitting relationship between the sealing member and the material taking and placing opening 1-1.
When solder paste needs to be stored, the push rod 4-3 is driven by the driving motor 4-2 to move into the refrigeration storage cabinet, and meanwhile, the solder paste placed on the tray 4-5 is driven to move into the refrigeration storage cabinet; the tray 4-5 extrudes the sealing element 4-6, and the sealing element 4-6 extrudes the spring 4-4, so that the sealing element is separated from the material taking and placing opening and moves towards the interior of the refrigerated storage cabinet;
as shown in FIG. 5, after the solder paste 5 placed on the tray 4-5 completely enters the refrigerated storage cabinet, the solder paste 5 is removed by other mechanisms, and the driving motor 4-2 drives the push rod 4-3 to ascend to return to the state shown in FIG. 4.
The device is not limited to be arranged vertically, and can also be arranged horizontally, as shown in fig. 6-1 and 6-2.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
