Description

Technical Field

[0001] This utility model relates to an automatic feeding device for hook springs. Background Technology

[0002] like Figure 1 As shown, the existing hook 100 includes a hook body 110, a spring piece 120, and a rivet 130. The spring piece 120 is riveted to the hook body 110 by the rivet 130, and can be opened and closed elastically by pressing the spring piece 120. Such hooks typically have a connecting hole at the end of the hook body for the pull strap to pass through, mainly serving as a connector for the pull strap of a child safety seat. For example, the pull strap assembly for a child safety seat and the child safety seat disclosed in Chinese Utility Model Patent CN218929265U can use a conventional hook or buckle structure as the connector on the pull strap body.

[0003] During the production of this type of hook, the spring sheet is usually fed by a vibratory feeder. However, the spring sheet is arranged on the discharge track of the vibratory feeder and is difficult to be transported. If the spring sheet is directly fed onto the transmission belt and then clamped, it is easy for the position to shift and it is difficult to position and clamp. This makes it difficult to transport the spring sheet to the corresponding work station after it is discharged. Utility Model Content

The device includes a needle and a lifting drive mechanism; the loading section is used to place a spring sheet; when the transfer seat is in the receiving position, one side of the loading section is connected to the discharge port, and the other side of the loading section is provided with a limiting section for the side of the spring sheet to abut and limit; the loading section is provided with a longitudinally extending through hole, and the positioning needle is inserted into the through hole in a vertically moving manner, so as to extend or retract into the through hole at the top of the loading section; the spring sheet is provided with a riveting hole, and when the positioning needle extends out at the top of the loading section, it is used to insert into the riveting hole of the spring sheet that falls into the loading section; the lifting drive mechanism is connected to the positioning needle and is used to drive the positioning needle to move up and down; the spring sheet feeding mechanism is used to transport the spring sheet on the transfer seat in the transfer position to the spring sheet feeding station.

The spring feeding mechanism 3 includes a discharge track 31 extending upward along a horizontal direction towards the machine platform 1. The discharge track 31 has a discharge port 311 for the spring 120 to be output.

[0021] The spring sheet transfer mechanism 4 includes a transfer fixed base 41 and a transfer movable base 42; the transfer fixed base 41 is fixed on the machine base 1, and the transfer movable base 42 is movably installed on the transfer fixed base 41 in a horizontal direction to translate between a receiving position and a transfer position; the spring sheet transfer mechanism 4 is used to receive the spring sheet 120 output from the discharge port 311 and transfer it to the transfer position.

[0022] The transfer seat 42 is provided with a material loading part 44, a positioning pin 45 and a lifting drive mechanism 46; the material loading part 44 is used to place a spring piece 120; when the transfer seat 42 is in the receiving position, one side of the material loading part 44 is connected to the discharge port 311, and the other side of the material loading part 44 is provided with a limiting part 442 for the side of the spring piece 120 to abut and limit.

[0023] The material-carrying part 44 is provided with a longitudinally extending through hole 441. The positioning pin 45 is inserted into the through hole 441 in a vertically moving manner so as to extend or retract into the through hole 441 at the top of the material-carrying part 44. The spring piece 120 is provided with a riveting hole 121. When the positioning pin 45 extends out from the top of the material-carrying part 44, it is used to insert into the riveting hole 121 of the spring piece that falls into the material-carrying part 44 to position the spring piece.

[0024] The lifting drive mechanism 46 is connected to the positioning pin 45 and is used to drive the positioning pin 45 to move up and down; the lifting drive mechanism 46 is a cylinder.

[0025] The spring feeding mechanism 5 is used to transport the springs on the transfer seat 42 in the transfer position to the spring feeding station.

[0026] This technical solution sets up a spring transfer mechanism 4 between the spring feeding mechanism 3 and the spring loading mechanism 5 to receive the springs, and sets up a positioning pin 45 to position the springs, so that the springs can be stably transferred on the loading part 44, which facilitates the spring loading mechanism 5 to transport them one by one.

[0029] This technical solution uses the guide section 43 in conjunction with the limit switch to guide and position the output spring, so that it can be stably transferred to the loading section 44.

[0030] A first sliding drive mechanism 47 for driving the transfer movable seat 42 to move horizontally is provided between the transfer fixed seat 41 and the transfer movable seat 42.

[0032] In this embodiment, the horizontal movement direction of the transport fixture 52 is consistent with the horizontal movement direction of the transfer seat 42.

[0033] Between the loading base 51 and the transport clamp 52, there is a second sliding drive mechanism 54 for driving the transport clamp 52 to move horizontally, a third sliding drive mechanism 55 for driving the transport clamp 52 to move vertically, and a rotation drive mechanism 56 for driving the transport clamp 52 to rotate around the vertical direction.
