Description

Technical Field

[0001] The utility model belongs to the technical field of connector processing devices, and in particular relates to a PogoPin spring pin in-mold injection molding multi-workpiece fast feeding device. Background Art

[0002] When the plastic is wrapped in a PogoPin mold, it is usually necessary to place the piece manually, or the robot automatically grabs and places it after the material is discharged from the vibration plate. However, no matter which solution is adopted, it is limited by the characteristics of the PogoPin product (the PogoPin product has a built-in spring, and there is a risk of spring shortage when it stays in the high temperature environment of the mold for more than 2 minutes), so the process requires that the discharge time be controlled within 1 minute. The existing manual and robot solutions can meet the needs of taking and placing a small amount of products. When more than 100 PCS workpieces are molded in the same mold at the same time, the manual discharge time basically needs to last more than 3 minutes, and the robot grabs and places the material for more than 2 minutes. In addition, due to the frequent switching of coordinates, the grasping accuracy cannot be guaranteed. The efficiency of the two existing solutions cannot be met, and it will also cause the process yield to deteriorate. Utility Model Content

[0026] In one embodiment of the present invention, Figures 1 to 5 As shown, a PogoPin multi-workpiece fast feeding device for in-mold injection molding of a pogo pin is provided, comprising an array frame 10, a mold feed plate 20, a feed offset plate 30, a guide frame 40 and a return spring 50, wherein the mold feed plate 20 is provided with a plurality of pogo pin feed holes 21, the feed offset plate 30 is provided with a positioning hole 31 and a plurality of pogo pin guide holes 32 which can correspond to the positions of the pogo pin feed holes 21 respectively, the guide frame 40 is connected to the mold feed plate 20, and the return spring 50 is provided with a positioning hole 31 and a plurality of pogo pin guide holes 32 which can correspond to the positions of the pogo pin feed holes 21 respectively. The reset spring 50 is arranged on the inner side of the guide frame 40, the feed offset plate 30 is placed on the mold feed plate 20 and is located in the guide frame 40 and contacts the reset spring 50, and a positioning pin 11 for inserting into the positioning hole 31 is provided at the bottom of the alignment frame 10, and an external force is applied to the alignment frame 10 to control the feed offset plate 30 to compress the reset spring 50 until each of the spring needle guide holes 32 is aligned one by one with each of the spring needle feed holes 21.

[0027] The PogoPin spring pin in-mold injection molding multi-workpiece rapid loading device provided by the embodiment of the utility model, when initially used, the positioning pin 11 of the alignment frame 10 is combined with the positioning hole 31 of the feed offset plate 30, and the product (PogoPin spring pin) is placed in the alignment frame 10, and the product is shaken manually or by an alignment machine; a spring pin guide hole 32 suitable for introducing the product is designed on the feed offset plate 30, and the product is introduced into the hole along the spring pin guide hole 32; due to the unequal gravity on both sides of the product, the gravity deviation is utilized, and the alignment of different frequencies can be used to effectively identify and sequence the direction of the product when it is aligned in the spring pin guide hole 32, and the product with the wrong direction can be adjusted when the alignment is shaken multiple times. Finally, if some of the products are not in the right direction and cannot be successfully aligned, they are taken out manually and placed correctly; the alignment frame 10 is taken out, and the residual material remaining on the feed dislocation plate 30 is poured out; the feed dislocation plate 30 is placed in the mold feed plate 20, and the guide frame 40 is used to position it corresponding to the mold feed plate 20; after confirming that the positioning is completed, the feed dislocation plate 30 is pushed manually, and when the feed dislocation plate 30 is pushed to the concentric position with the spring feed hole 21 of the mold feed plate 20, the product falls smoothly into the spring feed hole 21, and at the same time, under the influence of the reset spring 50, the feed dislocation plate 30 repeatedly returns to the original position before loading; the feed dislocation plate 30 is taken out, and the alignment frame 10 is repeatedly put into the machine to align the products, and the above-mentioned actions are repeated.

[0028] In one embodiment of the present invention, Figure 3 As shown, the guide frame 40 includes two symmetrically arranged U-shaped bars 41, and the U-shaped bars 41 are locked on the mold feed plate 20 by fasteners, and the fasteners can be screws or bolts, etc. The reset spring 50 is set on the vertical sides of the two U-shaped bars 41 on the same side. Specifically, the two U-shaped bars 41 are locked on the mold feed plate 20 symmetrically at intervals, and an area is formed on the mold feed plate 20, which is the area for the feed dislocation plate 30 to work. And the U-shaped bar 41 has two vertical sides on both sides, and the position of the vertical side is used to connect the reset spring 50. Through the contact of the reset spring 50 with the dislocation feed plate, when the feed dislocation plate 30 compresses the reset spring 50, once the external force is removed, under the action of the reset spring 50, the feed dislocation plate 30 can be reset to wait for the next cycle of work.
