Description

Technical Field

[0001] The utility model relates to the technical field of SMT auxiliary equipment, in particular to an SMT refrigerated auxiliary material turret. Background Art

[0002] SMT is the abbreviation of surface mount technology, which is a method of soldering components directly to the surface of PCB boards. The components soldered by SMT are usually surface mount devices, that is, patch components, referred to as SMD. This kind of component is small in size, and the use of traditional solder wire soldering is slow and has a high error rate. Therefore, reflow soldering is used for soldering. First, the solder paste is printed on the soldering position, then the component is placed, and finally reflow soldering is performed. Solder paste is a mixture of tin powder and flux. The flux and tin powder will react at room temperature and the flux will volatilize, so the solder paste usually needs to be refrigerated.

[0003] The existing solder paste is usually stored in a freezer, which is inconvenient to use and has a single storage type. The solder paste in the freezer must be used up before it can be replenished, otherwise the solder paste in the lower layer may expire due to long storage time and cannot be used. It is also stored in a freezer. There are also turrets for storing solder paste and taking solder paste, but the existing turrets usually use spline transmission between each layer of the storage plate and the rotating shaft. This transmission method has high requirements on the processing accuracy of the spline. At the same time, the installation, debugging and disassembly of the turret are inconvenient, and the transmission accuracy needs to be improved. Utility Model Content

[0037] The upright posts 13 are fixedly connected to the bottom plate 11 and the top plate 12 via angle brackets 14 , and two adjacent top plates 12 are fixedly connected via connecting pieces 15 .

[0038] The angle bracket 14 is fixedly connected to the column 13 by bolts, and then fixedly connected to the bottom plate 11 or the top plate 12 by bolts. The angle bracket 14 can increase the strength of the connection between the column 13 and the bottom plate 11 and the top plate 12. The connecting piece 15 is fixedly connected to two adjacent top plates 12 by bolts, thereby fixing the two adjacent racks 1 to increase the overall stability.

[0039] The driving assembly 2 includes a main shaft 25, which passes through the center of the top plate 12 and is rotatably connected to the bottom plate 11 and the top plate 12. The top of the main shaft 25 is connected to a power source, and the auxiliary material turret 3 is located outside the main shaft 25 and between the bottom plate 11 and the top plate 12. The main shaft 25 is rotatably connected to the top plate 12 through a first bearing 26, and the main shaft 25 is rotatably connected to the bottom plate 11 through a second bearing 27.

[0040] The first bearing 26 is fixedly connected to the top plate 12 by bolts, and the second bearing 27 is fixedly connected to the bottom plate 11 by bolts. The first bearing 26 and the second bearing 27 can limit the rotation axis of the main shaft 25.

[0041] The power source includes a driving motor 21 , a reducer 22 is fixedly installed below the driving motor 21 by bolts, the output shaft of the driving motor 21 is clamped with the input shaft of the reducer 22 , and the output shaft of the reducer 22 is fixedly connected to the head of the main shaft 25 through a coupling 24 .

[0042] A hoisting platform 23 is provided below the reducer 22, and the hoisting platform 23 can be hoisted below the roof, so as to hoist the drive motor 21 and the reducer 22. The reducer 22 and the hoisting platform 23 are fixedly connected by bolts.

[0043] The drive motor 21 can be a servo motor or a stepper motor. After the drive motor 21 is started, the output shaft of the drive motor 21 transmits power to the reducer 22, and the output shaft of the reducer 22 transmits power to the main shaft 25 through the coupling 24, driving the main shaft 25 to rotate.

[0044] The auxiliary material turret 3 includes a plurality of first placement trays 31 and a plurality of second placement trays 35.

The first placement trays 31 are used to place the packaged solder paste 5, and the second placement trays 35 are used to place the canned solder paste 6.

[0045] The expansion sleeve 33 adopts a Z2 type expansion sleeve, which has two inner and outer rings, the inner ring embraces the main shaft 25, and the outer ring embraces the middle of the first storage tray 31 or the second storage tray 35. The expansion degree of the inner and outer rings can be adjusted by adjusting the central bolt to achieve the fixing or release of the first storage tray 31 or the second storage tray 35.

[0046] When the main shaft 25 rotates, the first storage tray 31 and the second storage tray 35 can be driven to rotate through the expansion sleeve 33 .

[0047] A plurality of first material storage grooves 32 are provided on the edge of the top surface of the first placement tray 31 . The first material storage grooves 32 are used for placing canned solder paste 6 .

[0048] The outer diameter of the first material storage groove 32 is slightly larger than the outer diameter of the canned solder paste 6 and is used to limit the placement position of the canned solder paste 6 for easy access.

[0049] A limiting ring 36 is fixedly mounted on the top edge of the second placement plate 35 by bolts. The limiting ring 36 is penetrated by a plurality of second limiting grooves 37 . The second limiting grooves 37 are used for placing the supported solder paste 5 .

[0055] When it is needed, the driving motor 21 is used to drive the first storage tray 31 and the second storage tray 35 to rotate, and the packaged solder paste 5 and the canned solder paste 6 are rotated to the front.

[0056] During storage, the driving motor 21 is used to drive the first storage tray 31 and the second storage tray 35 to rotate, and the empty first material storage groove 32 and the second limiting groove 37 are rotated to the front.

[0059] The positioning sensor 41 is a known proximity sensor, and the sensing positioning sheet 42 is a metal sheet.

[0060] When the main shaft 25 drives the first placement tray 31 and the second placement tray 35 to rotate through the expansion sleeve 33, it can drive the sensing positioning piece 42 to rotate. When the sensing positioning piece 42 passes through the positioning sensor 41, it can be sensed by the positioning sensor 41, thereby recording the positions of the first placement tray 31 and the second placement tray 35, which is convenient for determining the starting position of rotation.
