Description

Technical Field

[0001] The utility model relates to the technical field of jewelry spring buckle processing equipment, in particular to a spring feeding device. Background Art

[0002] In today's society, jewelry has become an indispensable part of human life. Most non-elastic chain jewelry, such as necklaces, bracelets, waist chains, decorative belts, etc., are equipped with various types of connecting buckles at both ends for easy use. Among them, spring buckles are the most common and stable connecting buckles. They control the opening and closing of spring buckles through the cooperation of paddles and springs. The opening and closing action is passive, and external force is required to move the paddles to compress the springs. The closing is driven by the active rebound of the springs. Therefore, once the jewelry is connected and the spring buckle is locked, the connection part is not easy to slip off.

[0003] The existing spring buckle mainly consists of three parts, namely, the buckle body, the spring and the pick; the buckle body is a hollow tube, the buckle body is an arc shape with one side open, and the outer wall of the buckle body is provided with a slot-shaped through hole connected to the inside of the buckle body. In the process of assembling these three parts, the spring needs to be installed inside the buckle body first, and then the pick is installed inside the buckle body through the slot-shaped through hole, one end of which abuts against the spring, and the other end abuts against the end of the buckle body. Under normal conditions, the pick is subjected to the elastic force of the spring, and the pick abuts against the buckle body to complete the closed state. Traditionally, the assembly of spring buckles is completed by workers manually, and first of all, the labor cost is relatively high; secondly, during the assembly process, workers need to manually place the spring inside the buckle body. Since the spring is relatively small and thin, workers need to be more careful and meticulous during the process of taking and installing, which is more troublesome and laborious, and the assembly efficiency is low.

The top of the spring sliding push rod 51 is rotatably connected to the bottom of the spring push rod assembly 34. The spring sliding push rod 51 is drivingly connected to the power device 8. The power device 8 drives the spring sliding push rod 51 to move vertically reciprocatingly. The spring sliding push rod 51 simultaneously drives the spring push rod assembly 34 to move together. The spring push rod assembly 34 drives the L-shaped spring push connector 33 to rotate around its hinge, thereby driving the spring push rod 32 to reciprocate along its axis direction, thereby driving the spring push member 31 to reciprocate together.

[0058] In the utility model, a spring dividing mechanism 6 is also arranged between the spring vibration disk 1 and the spring reversing mechanism 2 along the moving path of the spring; the spring dividing mechanism 6 is used to sequentially separate the multiple springs moved out of the spring vibration disk 1 and allow each spring to enter the spring through-hole 221 individually.

[0059] Among them, the spring material distribution mechanism 6 includes: a material distribution cylinder mounting seat 61 fixedly connected to the spring vibration plate 1; a spring material distribution cylinder 62 fixedly arranged on the material distribution cylinder mounting seat 61, and the driving end of the spring material distribution cylinder 62 is fixedly connected to the spring material distribution connecting seat 63 arranged below the material distribution cylinder mounting seat 61; a material distribution slider slide rail assembly 64, the slider of the material distribution slider slide rail assembly 64 is fixedly connected to the material distribution cylinder mounting seat 61, the slide rail of the material distribution slider slide rail assembly 64 is fixedly connected to the spring material distribution connecting seat 63, and the spring material distribution cylinder 6 2 drives the spring material dividing connection seat 63 to move back and forth; the upper material dividing block 65, the upper material dividing block 65 is fixedly connected to the material dividing cylinder mounting seat 61, the upper material dividing block 65 is provided with an upper material dividing channel 651, and the upper material dividing channel 651 is communicated with the discharge end of the spring vibration plate 1 through the upper spring guide tube 652; the lower material dividing block 66, the lower material dividing block 66 is fixedly connected to the spring material dividing connection seat 63, the lower material dividing block 66 is provided with a lower material dividing channel 661, and the lower material dividing channel 661 is communicated with the spring receiving through hole 211 through the lower spring guide tube 662.

[0060] A dividing block 67 is provided on the upper dividing block 65, and the dividing block 67 is used to block the upper dividing channel 651, limiting that there is only one spring in the upper dividing channel 651 to perform the lower dividing channel 661; a return spring is provided between the dividing block 67 and the upper dividing block 65; a dividing stop pin 671 adapted to the dividing block 67 is installed on the spring dividing connecting seat 63, and the dividing stop pin 671 is used to push the dividing block 67 to move to the side close to the upper dividing block 65, and the dividing stop pin 671 corresponds to the position of the return spring and is provided on both sides of the dividing block 67.

[0061] The spring moved out through the spring vibration disk 1 enters the upper distribution channel 651 through the upper spring guide tube 652, and the spring distribution cylinder 62 pushes the spring distribution connecting seat 63 to move outward, driving the lower distribution block 66 and the distribution stop pin 671 to move together. During this process, the spring distribution connecting seat 63 drives the lower distribution channel 661 to align with the upper distribution channel 651, and the spring in the upper distribution channel 651 falls into the lower distribution channel 661; at the same time, the distribution stop pin 671 abuts and drives the distribution stop block 67 to block the upper distribution channel 651 to prevent the next spring from falling. In this way, each time the lower distribution channel 661 is aligned with the upper distribution channel 651, it can be ensured that there is only one spring in the upper distribution channel 651 and only the lowest spring falls into the lower distribution channel 661, thereby ensuring the normal feeding of the spring. After one spring is loaded, the spring distribution cylinder 62 drives the spring distribution connecting seat 63 to move in the opposite direction, and the lower distribution channel 661 is staggered with the upper distribution channel 651. At the same time, the reset spring pushes the distribution block 67 to reset and stop blocking the upper distribution channel 651, so that the subsequent spring falls and prepares for loading.

[0062] In order to facilitate the timely and rapid delivery of the spring in the lower spring conduit 662 to the spring through-hole 221, an air inlet hole 663 is provided on the lower distribution channel 661. The air inlet hole 663 is connected to an external blowing air source, and the blowing air source blows the spring in the lower spring conduit 662 to the spring through-hole 221.

[0064] The following is a brief description of its working principle based on the above structure:

[0065] The spring removed from the spring vibration disk 1 enters the upper material distribution channel 651 through the upper spring guide tube 652, and the spring material distribution cylinder 62 pushes the spring material distribution connecting seat 63 to move outward, driving the lower material distribution block 66 and the material distribution stop pin 671 to move together. During this process, the spring material distribution connecting seat 63 drives the lower material distribution channel 661 to align with the upper material distribution channel 651, and the spring in the upper material distribution channel 651 falls into the lower material distribution channel 661. The lower material distribution channel 661 is connected with the spring receiving through hole 211 through the lower spring guide tube 662, and the spring passes through the spring receiving through hole 211 into the spring through-hole 221.

At this time, the spring insertion hole 221 is aligned with the spring pushing member 31. The spring pushing member 31 passes through the spring pushing hole 212, and pushes the spring located in the spring insertion hole 221 to the side close to the assembly turntable 7 until it is pushed into the interior of the buckle body, thereby completing the spring loading action on the buckle body.
