Description

Technical Field

[0001] This invention relates to a transfer structure for a spring. Background Technology

[0002] To use spring materials in insertion welding machines or selective welding equipment, the springs need to be taped first. For example, Chinese Patent Document No. CN 217260859 U, published on August 23, 2022, discloses a spring assembly taping machine, including a frame, a base conveying and distributing mechanism for conveying and distributing spring bases, a turntable mechanism for carrying spring bases and changing work positions, a translational pushing mechanism for loading and unloading the turntable mechanism, a spring conveying track for conveying springs, a spring picking and transferring mechanism for clamping springs and transferring them to spring bases, a lifting and clamping mechanism for clamping claws on spring bases, bending the claws inward and lifting the spring bases to lock the claws onto the springs, a clamping and transferring mechanism for clamping assembled products on the turntable mechanism and transferring them to the taping station, a taping mechanism for taping and splicing carrier tape and loading products onto the carrier tape, and a winding mechanism for winding up the taped carrier tape. The base conveying and distributing mechanism, the turntable mechanism, and the springs... The conveyor track, spring picking and transferring mechanism, tape feeding mechanism, winding mechanism, and clamping and transferring mechanism are all mounted on the frame. The base conveying and distributing mechanism, spring picking and transferring mechanism, and clamping and transferring mechanism are arranged sequentially around the turntable mechanism along its rotation direction. The spring conveyor track is located on the side of the spring picking and transferring mechanism. The translational pushing mechanism is mounted on the turntable mechanism, with one end located at the loading station and the other end at the unloading station. The clamping and transferring mechanism is located between the turntable mechanism and the tape feeding mechanism. The winding mechanism is located at the unloading station of the tape feeding mechanism. The turntable mechanism has several evenly arranged positioning fixtures for supporting the spring bases. The clamping parts of the lifting and clamping mechanism are respectively set on each positioning fixture. This spring assembly and tape feeding machine is large, complex in structure, and expensive. Furthermore, the tape feeding and subsequent welding processes require multiple spring trimming operations, thus increasing its cost and warranting improvement. Summary of the Invention

[0003] The purpose of this invention is to provide a low-cost transfer structure for springs to overcome the shortcomings of the prior art.

[0004] A transfer structure for a spring designed for this purpose includes a spring, characterized in that it further includes an assembly bracket for assembling the spring, one end of the spring is provided with a bending protrusion and a bending opening surrounded by the bending protrusion, the assembly bracket is provided with an assembly groove for assembling one end of the spring and a limiting boss for assembling the bending opening, and the assembly bracket is provided with an assembly cavity for accommodating the spring.

[0005] Furthermore, at least one side of the assembly cavity is provided with an opening for assembling the spring.

[0006] The assembly bracket is provided with a first partition plate, which divides the assembly cavity into a first assembly cavity and a second assembly cavity. The first part of the spring is fitted into the first assembly cavity, and the second part of the spring is fitted into the second assembly cavity. The bending protrusion and bending opening of the spring are located in the first part of the spring. The number of turns in the first part of the spring is greater than the number of turns in the second part of the spring. The first assembly cavity is close to the assembly groove.

[0007] Furthermore, the assembly bracket is provided with a first partition plate and a second partition plate spaced vertically apart. The first partition plate and the second partition plate divide the assembly cavity into a first assembly cavity, a second assembly cavity, and a third partition cavity. The first part of the spring is fitted into the first assembly cavity, the second part of the spring is fitted into the second assembly cavity, and the third part of the spring is fitted into the third partition cavity. The bending protrusion and bending opening of the spring are located in the first part of the spring. The number of turns in the first part of the spring and / or the number of turns in the second part of the spring is greater than the number of turns in the third part of the spring. The first assembly cavity is close to the assembly groove.

[0008] Furthermore, a positioning seat is provided on one side of the first assembly cavity, and the assembly groove and the limiting boss are respectively provided on the positioning seat; the bending protrusion is located on the outside of the assembly bracket.

[0009] Furthermore, the positioning seat is provided with a guide slope for the spring to be bent and slidably engaged with the limiting boss.

[0010] Furthermore, the assembly groove includes a first assembly groove and a second assembly groove separated by a limiting boss, one end of the spring is engaged in the first assembly groove, and the limiting boss is engaged in the bending opening.

[0011] Furthermore, the first assembly groove and / or the second assembly groove are straight or curved.

[0012] Furthermore, it also includes a third assembly slot disposed on the positioning seat and connected to the first assembly slot, with one end of the spring being engaged in the third assembly slot.

[0013] Furthermore, the aforementioned transfer structure for the spring also includes a tray for transferring the assembly bracket and the spring. The tray is provided with two or more insertion slots for inserting the assembly bracket and the spring, and the bottom of the insertion slot is provided with insertion holes for inserting bending protrusions.

[0014] Furthermore, the width or length of the insertion slot is greater than the width or length of the mounting bracket.

[0015] In this invention, one end of the spring is provided with a bending protrusion and a bending opening formed by the bending protrusion. The assembly bracket is provided with an assembly groove for assembling one end of the spring and a limiting boss for assembling the bending opening. The assembly bracket is also provided with an assembly cavity for accommodating the spring. Thus, the spring is assembled with the assembly bracket, and the bending protrusion is located on the outside of the assembly bracket. When the spring and the assembly bracket are assembled together on the insertion slot on the tray, the bending protrusion is inserted into the insertion hole. At this time, the tray containing the spring and the assembly bracket can be placed on the conveyor belt of the automated production line. When the insertion welding machine or insertion machine needs to pick up the spring, the robotic arm controlled by the central controller picks up the assembly bracket with the spring from the tray, and then places the assembly bracket on the PCB board. The bending protrusion of the spring is inserted into the spring welding hole on the PCB board, and the bending protrusion of the spring is welded to the PCB board as one piece. Finally, the welded PCB board, spring, and assembly bracket are sent to the next process. The assembly bracket can be removed in the next process, or it can be removed when the PCB board is being inspected.

[0016] This invention eliminates the spring braiding process and the pre- and post-welding trimming steps, thus greatly reducing manufacturing costs and improving work efficiency.

[0017] In this invention, the number of coils in the first part of the spring is greater than the number of coils in the second part of the spring; or, the number of coils in the first part of the spring and / or the number of coils in the second part of the spring is greater than the number of coils in the third part of the spring. By adjusting the ratio of the number of coils of the spring that is inserted, the upper part of the spring can be prevented from becoming loose, thus ensuring the assembly quality of the welded and positioned spring. Furthermore, it can also be compatible with springs of different heights, thereby expanding the scope of application of this invention.

[0018] The assembly groove in this invention includes a first assembly groove and a second assembly groove separated by a limiting boss. One end of the spring is engaged in the first assembly groove, and the limiting boss is engaged in the bent opening. Further, the first assembly groove and / or the second assembly groove are straight or curved. Further, it also includes a third assembly groove disposed on the positioning seat and connected to the first assembly groove, and one end of the spring is engaged in the third assembly groove. By designing the assembly groove differently, it is possible to ensure that the welding foot of the spring is set at 90° with the welding assembly surface of the spring to the greatest extent. This not only improves the stability of the spring after welding, but also improves the perpendicularity between the spring after welding and the welding assembly surface, preventing the spring from becoming skewed after welding.

[0019] The width or length of the insertion slot in this invention is greater than the width or length of the assembly bracket, providing sufficient space for the robot to smoothly pick up and place items, which is beneficial to improving the efficiency of automated work.
