Description

Technical Field

[0001] The invention relates to the field of material exchange, and in particular to a material exchange device with double temperature zones to avoid temperature crosstalk. Background Art

[0002] Surface mount technology (SMT) is the most commonly used process technology in the current electronic packaging industry. The solder paste used in the process needs to be refrigerated during storage and needs to be warmed up before use. The management of the solder paste inevitably involves the process of transferring the solder paste from the cold storage area to the warming up area. As long as mechanical automatic placement is used, a window must be reserved between the cold storage area and the warming up area for the mechanical device to pass through. In order to minimize the loss of cold in the cold storage area, the prior art generally sets a heat preservation device, but the heat preservation device is limited to a heat preservation curtain, etc., which cannot provide a sufficiently good heat preservation function, causing the cold in the cold storage area to leak.

[0003] In order to achieve a better sealing effect, other manufacturers have specially set up independently operated sealing doors. The mechanism for entering and exiting materials is independent of the mechanism for opening the sealing door and they operate independently, which complicates the equipment structure and increases the production and maintenance costs of the equipment. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a material exchange device with dual temperature zones to avoid temperature crosstalk.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A dual-temperature zone material exchange device for avoiding temperature crosstalk, comprising a dual-temperature zone baffle, an elastic component, a tray, a seal and an electric push rod; the electric push rod comprises a push rod and a sleeve;

[0007] The tray is fixedly mounted on the end of the push rod;

[0008] The dual-temperature zone partition is provided with a material access opening;

[0009] The size of the sealing member is matched with the material taking-in and putting-out opening. The sealing member is movably sleeved on the push rod. The elastic component is sleeved on the push rod and is located between the sealing member and the sleeve.

[0010] On the basis of the above, the present invention can also be improved as follows:

[0011] Furthermore, the material access opening and the sealing member are both truncated cone-shaped; the upper bottom surface diameter of the sealing member is smaller than the lower bottom surface diameter of the material access opening, and the lower bottom surface diameter of the sealing member is larger than the upper bottom surface diameter of the material access opening; the elastic member is sleeved on the push rod, with one end of the elastic member resting on the sealing member and the other end resting on the sleeve. Here, for the truncated cone shape, the end surface with a smaller diameter is the upper side, and the end surface with a larger diameter is the lower side.

[0012] Furthermore, the elastic component is a spring; a spring baffle is provided on the sleeve;

[0013] Furthermore, the push rod is arranged vertically or horizontally; the dual-temperature zone partition is arranged horizontally or vertically.

[0014] Compared with the prior art, the present invention has the following technical effects:

[0015] The dual-temperature zone material exchange device for avoiding temperature crosstalk of the present invention can seal the refrigerator during the process of exchanging solder paste inside and outside the refrigerator, thereby preventing temperature crosstalk and improving the storage quality of solder paste. Only one mechanism is used to simultaneously perform the dual functions of sealing the opening and closing doors and exchanging materials, thereby simplifying the equipment structure and reducing the equipment cost.

[0034] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0035] Please refer to Figure 1-Figure 3 As shown, a dual-temperature zone material exchange device to avoid temperature crosstalk; including a sleeve 4-1, a drive motor 4-2, an electric push rod composed of a push rod 4-3 and a spring 4-4, a tray 4-5, a seal 4-6, a spring baffle 4-7 and a drive motor 4-2; the spring baffle 4-7 is fixed on the sleeve 4-1.

[0036] The push rod 4-3 is inserted into the sleeve 4-1;

[0037] The driving motor 4-2 drives the push rod 4-3 to extend and retract in the sleeve 4-1;

[0038] The tray 4-5 is fixedly mounted on the free end of the push rod 4-3;

[0039] The material access opening 1-1 provided on the refrigerated storage cabinet is a truncated cone type;

[0040] The sealing member 4-6 is in the shape of a truncated cone and is movably mounted on the push rod 4-3. The diameter of its upper bottom surface is smaller than the diameter of the lower bottom surface of the material access port, and the diameter of its lower bottom surface is larger than the diameter of the upper bottom surface of the material access port. The spring 4-4 ​​is mounted on the push rod 4-3, one end of which is against the sealing member 4-6, and the other end is against the spring baffle 4-7 fixed on the sleeve 4-1. In the initial state, the sealing member 4-6 is stuck in the material access port 1-1 under the elastic force of the spring, so as to achieve sealing inside and outside the cabinet 1.

[0041] like Figure 4 As shown, in the default state, the dual temperature zone material exchange device for avoiding temperature crosstalk is in Figure 4 In the position shown, the seal 4-6 seals the material access opening; the tray 4-5 is located outside the dual-temperature zone partition 1, and the solder paste to be stored in the refrigerated storage cabinet can be placed on the tray 4-5. Please note that there is no fixed bonding relationship between the tray 4-5 and the seal 4-6, so if the push rod 4-3 continues to push upward, the tray 4-5 can be higher than the dual-temperature zone partition 1 by a certain distance, and the seal 4-6 continues to be sealed in the material access opening 1-1 due to its adaptation relationship with the material access opening 1-1.

[0042] When solder paste needs to be stored, the push rod 4-3 moves into the cold storage cabinet under the drive of the drive motor 4-2, and at the same time drives the solder paste placed on the tray 4-5 to move into the cold storage cabinet; the tray 4-5 squeezes the seal 4-6, and the seal 4-6 squeezes the spring 4-4, so that the seal is separated from the material access port and moves into the cold storage cabinet together;

[0043] like Figure 5 As shown, when the solder paste 5 placed on the tray 4-5 completely enters the cold storage cabinet, the solder paste 5 is taken away by other mechanisms, and the driving motor 4-2 drives the push rod 4-3 to rise and return to the state as shown in FIG. Figure 4 Status shown.

[0044] The device is not limited to vertical arrangement, but can also be arranged horizontally, such as Figure 6-1 and Figure 6-2 shown.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
