[0002] String lights are a common decorative item in daily life. During production, the entire roll of wire is first cut and stripped, then terminals are punched, and then soft tips and light bulbs are sequentially attached to the wire segments. After assembly, a long string of lights is formed.

[0003] Announcement No.: CN206794556U, entitled "A Light String Assembly Mechanical Device", includes a light string assembly device body, a frame at the bottom of the light string assembly device body, a clamping station on the outside of the mounting plate, a wire inlet fixing post on one side of the clamping station, a flexible head installation robot on one side of the wire inlet fixing post, a flexible head storage tank on one side of the flexible head storage tank, a flexible head conveyor belt on one side of the flexible head conveyor belt, a terminal punching device on one side of the terminal punching device, a bulb storage tank on one side of the terminal punching device, a bulb conveyor belt on one side of the bulb storage tank, a bulb installation robot on one side of the bulb conveyor belt, and an mounting frame on one side of the bulb installation robot.

[0004] In the existing light string assembly device, the assembly of the soft head relies on a robotic arm. This structure has poor compatibility for installing soft heads that do not have obvious directional characteristics, and the accuracy during the assembly process is also low, which is not conducive to the installation of soft heads and busbars. Therefore, it does not meet the existing requirements. To address this, an automatic assembly mechanism for the soft heads of light string busbars is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic assembly mechanism for the flexible connector of a light string busbar, so as to solve the problem that in the existing light string assembly device mentioned in the background art, the flexible connector assembly relies on a robot arm. This structure has poor compatibility with complex-shaped flexible connectors, and the accuracy in the assembly process is also low, which is not conducive to the installation of the flexible connector and the busbar.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic assembly mechanism for a light string busbar flexible connector, comprising: a flexible connector feeding mechanism for conveying the flexible connector; a flexible connector clamping and detection mechanism installed at the front end of the flexible connector feeding mechanism for clamping and limiting the flexible connector; a flexible connector flipping and pushing mechanism installed in front of the flexible connector clamping and detection mechanism for flipping and pushing the flexible connector; a wire clamping assembly installed on the conveying table for limiting the wire; a wire clamping mechanism installed on the side of the flexible connector feeding mechanism for clamping the wire head; and a drive mechanism installed inside the assembly table.

[0007] Preferably, the soft tip flipping and pushing mechanism is divided into a flipping component and a pushing component. The flipping component includes a mounting rod for installing the soft tip. A rotating mechanism for controlling the mounting rod to rotate from the vertical direction to the horizontal direction is installed on one side of the mounting rod. A drive wheel is provided at one end of the mounting rod to drive it to rotate radially to the left or right.

[0008] Preferably, the pushing assembly includes a reset block located above the drive wheel and a control block located below the drive wheel, with a left and right limiting cavity formed between the reset block and the control block for controlling the position of the drive wheel. The pushing assembly also includes a pusher extending to the soft-tip clamping and detection mechanism.

[0009] Preferably, the soft tip clamping and detection mechanism includes a first clamp for clamping the soft tip, and two sets of driving blocks for driving the first clamp to move back and forth and up and down. The soft tip clamping and detection mechanism also includes a detection mechanism located at its front end for detecting the direction of the soft tip, and a top block for lifting the soft tip is installed on one side of the first clamp.

[0010] Preferably, the soft-tip feeding mechanism includes a soft-tip feeding vibrating drum and a soft-tip conveying track for connecting the soft-tip feeding vibrating drum and the soft-tip flipping and pushing mechanism.

[0011] Preferably, the wire clamping assembly includes a second clamp, and a spacer is disposed between the second clamps.

[0012] Preferably, the wire clamping mechanism includes a third clamp that matches the wire diameter, and one end of the third clamp is equipped with a motion mechanism for closing and moving up and down.

[0013] Preferably, the drive mechanism includes a reducer, a drive shaft, and a rocker arm for connection to the motor output. The reducer and the drive shaft are driven by a chain. The drive shaft is provided with multiple cams. One end of the rocker arm corresponds to a cam. The reducer drives the drive shaft to rotate, thereby driving the cam to perform circular motion. The cam indirectly drives the other end of the rocker arm to perform up-and-down reciprocating motion. The rocker arm is fixed to the base and performs lever motion. The other end of the rocker arm is connected to a soft-head feeding mechanism, a soft-head clamping and detection mechanism, a soft-head flipping and pushing mechanism, a wire clamping assembly, and a wire gathering mechanism via a connecting rod.

[0014] Preferably, the drive mechanism further includes a transmission steering unit, which is connected to the drive shaft via a chain and is used to change the rotation direction of the drive shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) In this utility model, the soft head is fed into the soft head clamping and detection mechanism and the soft head flipping and pushing mechanism by the soft head feeding mechanism. The direction of the soft head is detected by the detection mechanism. The soft head that has been moved to this location is flipped and put into place by the flipping component. After being put into place, it is pushed into the busbar by the pushing component. In this process, the assembly problem of soft head without obvious directional characteristics can be solved, and the assembly accuracy is higher. The busbar and soft head are more convenient to install. At the same time, the degree of automation is high and it is suitable for use in the production line.

[0017] (2) In this utility model, the busbar moves on the conveyor table at each station. The second clamp can clamp and limit the busbar, improving the stability of the busbar displacement process. The busbar first moves to the third clamp. The third clamp uses a motion mechanism to stretch the busbar and clamp it, so that the soft head can be more easily fitted onto the busbar in the protruding and closed state, indirectly improving the installation accuracy of the soft head.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1 , Figure 6 An embodiment of this utility model provides an automatic assembly mechanism for flexible connectors of light string busbars, comprising: a flexible connector feeding mechanism 1, which includes a flexible connector feeding vibrating drum 101 and a flexible connector conveying track 102 for connecting the flexible connector feeding vibrating drum 101 and the flexible connector flipping and pushing mechanism 3. The flexible connector feeding mechanism 1 feeds the required flexible connectors into the flexible connector conveying track 102 through the flexible connector feeding vibrating drum 101. The flexible connectors in the flexible connector conveying track 102 move to the flexible connector flipping and pushing mechanism 3 for subsequent assembly operations.

[0028] like Figure 3 , Figure 5 , Figure 6As shown, the soft head clamping and detection mechanism 2 is installed at the front end of the soft head feeding mechanism 1. The soft head clamping and detection mechanism 2 includes a first clamp 201 for clamping the soft head, and two sets of driving blocks 202 for driving the first clamp 201 to move back and forth and up and down. The soft head clamping and detection mechanism 2 also includes a detection mechanism 203 located at its front end for detecting the direction of the soft head. A top block 204 for lifting the soft head is installed on one side of the first clamp 201. The soft head flipping and pushing mechanism 3 is installed in front of the soft head clamping and detection mechanism 2. The soft head flipping and pushing mechanism 3 is divided into a flipping component and a pushing component. The flipping component includes a component for... The mounting rod 301 for mounting the soft tip has a rotation mechanism 305 on one side that controls the mounting rod 301 to rotate from the vertical direction to the horizontal direction. One end of the mounting rod 301 is provided with a drive wheel 302 that drives it to rotate 90 degrees to the left or right in the radial direction. The pushing assembly includes a reset block 306 located above the drive wheel 302 and a control block 303 located below the drive wheel 302. A left and right limiting cavity is formed between the reset block 306 and the control block 303 for controlling the position of the drive wheel 302. The pushing assembly also includes a pusher 304 that extends to the soft tip clamping and detection mechanism 2.

[0029] When the mounting rod 301 inserts the flexible head, the rotating mechanism 305 operates, causing the mounting rod 301 to rotate downwards by 90°. At the same time, the drive wheel 302 rotates axially by 90° along the arc trajectory of the control block 303. At this time, the mounting rod 301 is exactly above the top block 204, and the drive wheel 302 is located in the limiting cavity of the reset block 306. The width direction of the mounting rod 301 is consistent with the width direction of the large end of the flexible head. Then, the top block 204 pushes the flexible head up, allowing the mounting rod 301 to be inserted into the flexible head. Then, the rotating mechanism 305 controls the mounting rod 301 to reset. The reset stroke is also completed by the cooperation of the reset block 306 and the control block 303. During reset, the mounting rod 301 rotates 90° in two opposite directions. At this time, the width direction of the small end of the flexible head is consistent with the width direction of the busbar. The push head 304 moves horizontally, allowing the flexible head to be fitted outside the busbar, completing the assembly process.

[0030] The reset block 306 and control block 303 form left and right limiting cavities for controlling the position of the drive wheel 302. The control block 303 is responsible for active control; by translating the control block 303, the position of the drive wheel 302 within the left or right limiting cavity is changed. Ultimately, the mounting rod 301 is controlled to rotate axially for smooth installation of the flexible head. The flexible head has tapered ends and a through hole with a width consistent with the width of the folded busbar.

[0031] Please see Figure 4 , Figure 7The wire clamping assembly 4 is installed on the conveyor table, and the wire clamping mechanism 5 is installed on the side of the soft head feeding mechanism 1. The wire clamping assembly 4 includes a second clamp 401, and a partition 402 is provided between the second clamps 401. The wire clamping mechanism 5 includes a third clamp 501 that matches the wire diameter. One end of the third clamp 501 is equipped with a motion mechanism 502 for closing and moving up and down. The busbar moves on the conveyor table at each station. The second clamp 401 can clamp and limit the busbar, improving the stability of the busbar displacement process. The busbar first moves to the third clamp 501. The third clamp 501 stretches the busbar through the motion mechanism 502 and clamps it, so that the soft head can be more easily fitted onto the protruding and closed busbar, indirectly improving the installation accuracy of the soft head.

[0032] Please see Figure 2 The drive mechanism 6 includes a reducer 601, a drive shaft 605, and a rocker arm 604 connected to the motor output. The reducer 601 and the drive shaft 605 are driven by a chain. The drive shaft 605 is provided with multiple cams 602. One end of the rocker arm 604 corresponds to one of the cams 602. The reducer 601 drives the drive shaft 605 to rotate, thereby causing the cams 602 to perform circular motion. The cams 602 indirectly drive the other end of the rocker arm 604 to perform up-and-down reciprocating motion. The rocker arm 604 is fixed to the base and performs lever motion. The other end of the rocker arm 604 is connected to the motor output. The drive mechanism 6 is connected via a linkage to the soft-tip feeding mechanism 1, the soft-tip clamping and detection mechanism 2, the soft-tip flipping and pushing mechanism 3, the wire clamping assembly 4, and the wire clamping mechanism 5. The drive mechanism 6 also includes a transmission steering gear 603, which is connected to the transmission shaft 605 via a chain and is used to change the rotation direction of the transmission shaft 605. Through the configuration of the drive mechanism 6, the corresponding actions can be performed at the soft-tip feeding mechanism 1, the soft-tip clamping and detection mechanism 2, the soft-tip flipping and pushing mechanism 3, the wire clamping assembly 4, and the wire clamping mechanism 5 via the linkage.
