Water diversion core staggered material receiving device and method

Abstract

The invention discloses a water diversion core staggered material receiving device and method. The device is arranged between a vibration disc and a feeding mechanism of a water diversion core; the device comprises a mechanism body and a transferring piece installed on the mechanism body, one end of the transferring piece is connected with a discharging opening of the vibration disc, the other endof the transferring piece is connected with the mechanism body, at least one water diversion core is temporally stored in the transferring piece, the water diversion core at the discharging opening of the vibration disc is conveyed to the mechanism body through the transferring piece, and the mechanism body is arranged on the feeding mechanism in a staggered manner. According to the water diversion core staggered material receiving device and method, the problem about to-be-staggered water diversion core collision bounce is eliminated, the staggered gesture of the water diversion core is determined, and the rate that the water diversion core generates material blockage during staggering is greatly reduced.

Description

technical field [0001] The invention relates to a feeding device for a water guiding core, in particular to a dislocation feeding device and method for the water guiding core. Background technique [0002] During the assembly process of the water writing pen, the water guiding core (such as figure 1 The water writing core of the water writing pen shown) is resonantly driven by a small vibrating disc (not shown in the figure), and spirally climbs along the arc-shaped disc surface. Arranged in an orderly manner, arranged at the discharge port for use, dislocate the water guide cores arranged by the vibration plate to the feeding mechanism for assembly through the dislocation mechanism, so as to realize the fast and orderly feeding of the water guide cores, so as to match the high-speed automatic operation of the water writing pen. Assembly production. [0003] Existing misalignment mechanisms of the water core, such as figure 2 As shown, the driving cylinder 1 is used to d...

AI Technical Summary

Problems solved by technology

[0004] Judging from the above-mentioned existing feeding process of the water diversion core and the structure of the dislocation mechanism, there are three problems that are relatively easy to cause trouble:

[0005] 1. The structure of the water guide core of the water writing pen is special. The size of the water guide core is small and slender (0.8mm). Therefore, it is difficult to choose the support point of the vibration plate for the water guide core. If you choose the boundary line A between the water writing pen head and the water guide core support points, such as figure 1 As shown, it is relatively easy to realize, but the center of gravity of the pen tip will be very unstable, which is very easy to cause rollover, so the position of the tangent line B of the pen tip can only be selected as the support point, as shown in figure 1 shown

However, because the step surface of the ring tangent line B has a very small gap size (0.23mm), it is very difficult to process the flow channel of the vibrating plate. Therefore, when the vibrating plate is actually used, the feeding speed cannot be too fast, so the water diversion core is caused. There will be a difference between the feed rate and the demand rate, causing intermittent standstills

[0006] 2. The gap between the discharge port of the vibrating plate and the arc-shaped receiving port 4 of the dislocation plate should not be greater than 1 / 2 of the connection diameter of the water diversion core iron. The high-frequency collision between the discharge port of the vibrating plate and the material receiving port 4 will damage the mechanism and make it difficult to adjust. Moreover, after the vibrating plate vibrates for a long time, the position will change slightly, the gap will expand or the pen core will be damaged. It may cause the material to be stuck or the water core to be broken;

[0007] 3. When the vibrating plate is discharged, it is in a state of high-frequency vibration, while the arc-shaped material opening of the dislocation plate is in a static state, so there is a transition from dynamic to static in the water diversion core, because the above question 2 has been said However, there must be a gap between the two mechanisms, so before the misalignment plate 3 does not move, there are still constant collisions and jumps between the water diversion core to be misaligned and other water diversion cores in the vibrating plate, and the position and posture are all changing at any time In the unfixed state, when the misalignment plate is in motion, if the posture of the water guide core is incorrect, there will be a risk of scratching the water guide core
