Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lifting devices, in particular to a lifting and rotating device for cleaning. Background Art
[0002] Taking the lead frame as an example, after welding, there will be flux residue and other stains on the surface of the lead frame, which must be cleaned in a cleaning tank before entering the subsequent process. Since lead frames are easily damaged by collision and friction with each other, they need to be inserted into the card slot of the material box before cleaning to ensure that there is a certain distance between two adjacent lead frames. This can not only prevent damage to the lead frame surface, but also facilitate the comprehensive cleaning of the lead frame. Compared with the method of placing the material box statically in the cleaning tank for cleaning, the method of lifting and rotating the material box in the cleaning tank for cleaning is more conducive to improving cleaning efficiency. The problem is: there are many ways to achieve the lifting and rotation of the material box in the existing technology, but most of them require two power sources to achieve lifting and rotation. Utility Model Content

[0007] When the motor is started and the cylinder is located in the vertical section of the guide groove, it is used to move the clamping mechanism up and down; when the motor is started and the cylinder is located in the threaded section of the guide groove, it is used to move the clamping mechanism up and down and rotate at the same time.
[0008] Furthermore, a curved plate is provided on a side of the rack away from the gear, and a curved outer wall of the curved plate is in close contact with the outer tube.

BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 Shows the structural diagram of the lifting and rotating device;
[0012] Figure 2 Shows the plan view of the rack, adjustment rod and smooth rod;
[0013] Figure 3 A perspective view of the outer tube is shown. DETAILED DESCRIPTION
[0014] like Figure 1-Figure 3 As shown, this embodiment provides a lifting and rotating device for cleaning, including a motor 41 , a gear 42 , a rack 43 , an outer tube 44 and an adjusting rod 45 .
[0015] The top of the outer tube 44 is connected to the track 3, and the track 3 is used to move the device horizontally to other positions. The bottom of the outer tube 44 is opened, and the adjusting rod 45 and the rack 43 are both arranged in the outer tube 44, and the outer wall of the adjusting rod 45 is close to the inner wall of the outer tube 44. The bottom of the rack 43 is provided with a round block 451, and the top of the adjusting rod 45 is rotatably connected to the round block 451. The motor 41 is fixed to the outer wall of the outer tube 44, and the output shaft of the motor 41 is connected to the gear 42. The side wall of the outer tube 44 is provided with an avoidance groove, and the gear 42 and the rack 43 are engaged at the avoidance groove. The bottom of the adjusting rod 45 is used to connect the clamping mechanism 2, and the clamping mechanism 2 is used to clamp the lead frame box. The outer wall of the adjusting rod 45 is provided with a guide groove 452, which includes a vertical section and a threaded section provided at the top of the vertical section. The inner wall of the outer tube 44 is provided with a cylinder 441, and the cylinder 441 matches the guide groove 452.
[0016] In order to improve the stability of the device, this embodiment adopts the following two measures:
[0017] First, as Figure 1 、 Figure 2 As shown, an arc-shaped plate 431 is provided on the side of the rack 43 away from the gear 42 , and the arc-shaped outer wall of the arc-shaped plate 431 is in close contact with the outer tube 44 .
[0018] Second, if Figure 1 、 Figure 2 As shown, a smooth rod 46 is provided at the bottom of the adjusting rod 45. The diameter of the smooth rod 46 is smaller than that of the adjusting rod 45. The bottom of the smooth rod 46 is used to connect to the clamping mechanism 2. A spring 461 is provided on the outer periphery of the smooth rod 46. The two ends of the spring 461 are respectively connected to the adjusting rod 45 and the clamping mechanism 2.
[0019] The method of use is as follows: when the clamping mechanism 2 clamps the material box and has not yet lowered the material box into the cleaning tank, the cylinder 441 is located in the vertical section of the guide groove 452; then the motor 41 is started, causing the adjusting rod 45, the clamping mechanism 2 and the material box to move downward as a whole. Since the cylinder 441 is located in the vertical section of the guide groove 452, the adjusting rod 45 will not rotate at this stage. This stage is only used to move the material box downward and lower it into the cleaning tank; after the material box is lowered into the cleaning tank, the cylinder 441 is located in the vertical section of the guide groove 452 and the threaded section is connected. At this stage, the motor 41 continues to drive the second gear 42, and the cylinder 441 moves along the threaded section of the guide groove 452, which will cause the adjusting rod 45 to rotate. In this stage, the adjusting rod 45 not only moves downward but also rotates, which means that the material box in this stage will move downward and rotate at the same time; after the material box rotates a certain angle, the motor 41 drives the second gear 42 in the reverse direction, causing the material box to move upward and rotate a certain angle, and then the motor 41 drives the second gear 42 in the forward direction, and repeats multiple cycles until the cleanliness of the lead frame meets the requirements.
[0020] In summary, when cleaning the lead frame, the device can rotate the material box while moving it up and down, which greatly improves the cleaning efficiency of the lead frame; only one power source, the motor 41, is required to achieve the lifting and rotation of the material box, which has an ingenious structure and saves power source.
[0021] The above embodiments are only used to illustrate the technical ideas and features of the present invention and are not intended to be exclusive or limitative of the present invention. It should be understood by those skilled in the art that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
