Description

Technical Field

[0001] This utility model belongs to the field of automated processing equipment technology, and specifically refers to a twisting mechanism that can automatically twist copper wire light strips. Background Technology

[0002] Copper wire LED light strips are made by soldering LED lights onto a long copper wire using a special processing technique.

[0003] After being connected to a power source, it emits light to form a light strip. To make the light strip more aesthetically pleasing, it can be bent into different shapes. For example, the light strip can be made into the shape of a firecracker by twisting the wire. There are single-sided firecracker styles and double-sided firecracker styles. The difficulty of making different styles of copper wire light strips varies.

[0004] The most common way to twist the wire is by hand, which is inefficient and results in "firecrackers" that cannot be made in a consistent shape and length. The copper wire lamp twisting process can also be broken down into several steps, with some steps completed by equipment. Overall, because copper wire lamp strips do not have a specific shape, to create firecracker-style lamps with high efficiency and consistent shape, specialized automated equipment is necessary. Summary of the Invention

[0005] The purpose of this invention is to provide a wire twisting mechanism for copper wire lamps that can be manufactured efficiently and maintain a consistent style.

[0006] The purpose of this utility model is achieved as follows: a wire twisting mechanism for a copper wire lamp includes a conveyor table for conveying copper wire lamp strips, the conveyor table being driven by a conveyor motor to process the copper wire lamp strips, and a wire twisting device and a wire organizing device. The wire twisting device and the wire organizing device are arranged opposite each other on both sides of the conveyor table, cooperating with each other to complete the wire twisting process. The end of the wire twisting device is provided with a rotatable and openable wire twisting clamp, which can clamp the copper wire lamp strip and complete the twisting by its own rotation. The end of the wire organizing device is provided with an openable wire organizing clamp, and the wire twisting clamp... Before twisting the wire, the wire guide clamp completes the combing of the copper wire LED strip. The twisting clamp and the wire guide clamp are on the same axis. Under the action of their respective drive devices, they move back and forth in the axial direction. That is, the wire guide clamp moves towards the twisting clamp to complete the combing of the copper wire LED strip, and then retracts to prepare to comb the next section of the copper wire LED strip. After the wire guide clamp completes the combing, the twisting clamp moves towards the wire guide clamp in an open form. After reaching the position, it closes, and the copper wire LED strip is placed between the twisting clamps. Then it retracts, pulls the copper wire LED strip, and begins to rotate itself, driving the section of the copper wire LED strip to rotate, thus completing the twisting.

[0007] In a further optimization, the twisting device and the wire organizing device are combined, and at least one set is provided on the conveyor platform. The twisting device and the wire organizing device in each set are staggered with the twisting device and the wire organizing device in the adjacent set, which can complete the twisting of the double-sided firecracker pattern.

[0008] Further optimization involves installing a wire pushing device and a wire pulling device on the conveyor platform. These two devices are positioned opposite each other on both sides of the conveyor platform and at the front end of the conveyor platform's flow path. The wire pulling device and the wire twisting device are located on the same side of the conveyor platform. The purpose of these two devices is to pre-make the copper wire LED strip into U-shaped sections, which facilitates quick and easy twisting during the twisting process.

[0009] Further optimization involves providing a push rod at the end of the push wire device and a pull wire clamp at the end of the pull wire device. Both the push rod and the pull wire clamp can reciprocate along two adjacent parallel axes to form the copper wire light strip into U-shaped sections. This is mainly achieved by using the axial movement of the push rod and the pull wire clamp to pull each U-shaped section of the copper wire light strip into a style with consistent shape and length.

[0010] Further optimization involves installing a drive rod and a drive motor below the conveyor platform, connected to each other. The drive rod has several cams, and the drive motor rotates the drive rod, causing all the cams to rotate together. The twisting device has a linkage device I, which connects to a corresponding cam, driving the twisting clamp to reciprocate axially. The wire organizing device has a linkage device II, which connects to a corresponding cam, driving the wire organizing clamp to reciprocate axially. The pushing device has a linkage device III, which connects to a corresponding cam, driving the pushing rod to reciprocate axially. The pulling device has a linkage device IV, which connects to a corresponding cam, driving the pulling clamp to reciprocate axially. The cams corresponding to the twisting device, wire organizing device, pushing device, and pulling device have different angles to ensure the sequential driving order of each device.

[0011] Further optimization involves equipping the twisting device, cable management device, cable pusher, and cable puller with cylinders or motors to drive the twisting clamp, cable management clamp, cable pusher, and cable puller to reciprocate axially. This optimization is an alternative drive option besides the aforementioned cam and linkage drive methods.

[0012] In a further optimization, the twisting device is equipped with a rotary motor, and the twisting clamp is connected to the rotary motor. The rotary motor drives the twisting clamp to rotate. After the twisting clamp pulls the copper wire LED strip, the rotary motor rotates, driving the twisting clamp to complete the twisting.

[0013] Further optimization involves a limiting device on the same side of the cable management device. The limiting device has a limiting plate and a connecting rod or cylinder that drives the limiting plate to move axially. The limiting plate is on the same axis as the cable twisting clamp and the cable management clamp. When the cable twisting clamp pulls the copper wire light strip, the limiting plate moves toward the cable twisting clamp. At this time, the limiting plate is inserted into the opening of the U-shaped copper wire light strip. The cable twisting clamp begins to rotate and tighten the U-shaped copper wire light strip. When the cable twisting clamp reaches the position where the limiting plate stops and contacts the limiting plate, the tightening action is completed. The limiting plate and the cable twisting clamp then return to their initial positions.

[0014] Further optimization involves providing several spacer bars on the conveyor platform. When the wire twisting clamp and wire organizing clamp move axially, they act between two adjacent spacer bars. Through the positioning of the spacer bars, the copper wire LED strip can be precisely and quickly pulled into a U-shape and arranged between the spacer bars of the conveyor platform.

[0015] Further optimization involves designing the conveyor platform in a circular shape, which saves space and enables the copper wire light strip to rotate rapidly.

[0016] The outstanding and beneficial technical effects of this utility model compared with the prior art are as follows: 1. This mechanism can quickly and efficiently complete the twisting of copper wire light strips, and can produce both single-sided and double-sided "firecracker lights"; 2. Through the cooperation of the twisting device, the wire organizing device, and the limiting device, the copper wire light strips can be twisted into uniform lengths and uniform twisting shapes, improving the forming quality of the copper wire light strips; 3. The pushing device and the pulling device can pre-pull the copper wire light strips into a U-shape, making it easier to twist and form them later; 4. The intermittent transmission of the conveyor table can accurately deliver the copper wire light strips to each processing station to complete the wire pulling and twisting processes.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. In order to better understand the technical solution of the present invention, the following embodiments will be described.

[0031] Example 1

[0032] like Figures 1-7As shown, a wire twisting mechanism for a copper wire lamp includes a conveyor table 1 for conveying copper wire lamp strips. The conveyor table 1 is circular and driven by a conveyor motor 2. Several spacer bars 6 are installed on the conveyor table 1. Copper wire lamp strips 7 are arranged on the spacer bars 6 and conveyed to various processing stations for processing. The mechanism also includes a wire twisting device 10 and a wire organizing device 20. The wire twisting device 10 and the wire organizing device 20 are positioned opposite each other on both sides of the conveyor table 1 via a support frame, with their height maintained above the conveyor table 1. During operation, they act on the copper wire lamp strips 7 between adjacent spacer bars 6, working together to complete the wire twisting process. The end of the wire twisting device 10 is equipped with a wire twisting clamp 101 that is rotatable and can be opened and closed by a rotary motor 102. A drive cylinder is installed at the tail of the wire twisting clamp 101, controlling its opening and closing. The device can clamp the copper wire LED strip and twist it by rotating itself. The end of the wire management device 20 is provided with a closable wire management clamp 201, which is also driven by a cylinder. Before the twisting clamp 101 twists the wire, the wire management clamp 201 completes the combing work of the copper wire LED strip. The twisting clamp 101 and the wire management clamp 201 are on the same axis. Under the action of their respective driving devices, they move back and forth in the axial direction. That is, the wire management clamp 201 moves towards the twisting clamp 101 to complete the combing work of the copper wire LED strip, and then retracts to prepare to comb the next section of the copper wire LED strip. After the wire management clamp 201 completes the combing, the twisting clamp 101 moves towards the wire management clamp 201 in an open form. After reaching the position, it closes, and the copper wire LED strip is between the twisting clamps 101. Then it retracts, pulls the copper wire LED strip, and begins to rotate itself, driving the section of the copper wire LED strip to rotate, thus completing the twisting.

[0033] The twisting device 10 and the wire organizing device 20 on both sides of the conveyor table 1 can complete the single-sided twisting process of the copper wire LED strip, such as... Figure 7 As shown, this is the state that the copper wire light strip exhibits during the single-sided twisting process.

[0034] To ensure consistent tightening length and state, a limiting device 30 is provided on the same side of the cable management device 20. The limiting device 30 is equipped with a limiting piece 301 and a connecting rod device 302 or cylinder for driving the limiting piece 301 to move axially. The limiting piece 301 is on the same axis as the cable clamp 101 and the cable management clamp 201. When the cable clamp 101 pulls the copper wire light strip, the limiting piece 301 moves toward the cable clamp 101. At this time, the limiting piece 301 inserts into the opening of the U-shaped copper wire light strip 8, and the cable clamp 101 begins to rotate and tighten the U-shaped copper wire light strip 8. When the cable clamp 101 is tightened to the position where the limiting piece 301 stops and contacts the limiting piece 301, the tightening action is completed, and the limiting piece 301 and the cable clamp 101 each return to their initial positions.

[0035] The conveyor platform 1 is equipped with a wire pushing device 40 and a wire pulling device 50, which are arranged opposite each other on both sides of the conveyor platform 1 and located at the front end of the conveyor platform 1. The wire pulling device 50 and the wire twisting device 101 are located on the same side of the conveyor platform. The end of the wire pushing device 40 is equipped with a wire pushing rod 401, and the end of the wire pulling device 50 is equipped with a closable wire pulling clamp 501. Both the wire pushing rod 401 and the wire pulling clamp 501 can reciprocate in two adjacent parallel axes to make the copper wire light strip into U-shaped sections. This is mainly achieved by the axial movement of the wire pushing rod 401 and the wire pulling clamp 501, which pulls each U-shaped section of the copper wire light strip into a style with a consistent shape and length. The above two devices are designed to pre-make the copper wire light strip into U-shaped sections, which facilitates quick tightening and shaping during wire twisting.

[0036] The specific working principle is as follows: The copper wire LED strip to be processed is installed on the unwinding drum 901 on one side of the machine base 9. The copper wire LED strip 7 is pulled out and wound around the two winding wheels 902 to facilitate the pulling out of the copper wire LED strip. Finally, it passes through the wire tube 903 and is placed on the spacer bar 6 of the conveyor table. The conveyor table 1 drives the copper wire LED strip 7 to move. The linkage device Ⅲ 402 starts to work under the drive of the cam driven by the drive motor, driving the push rod 401 to move towards the copper wire LED strip 7 and push the copper wire LED strip 7 to the conveyor table. On the other side, a preliminary U-shape is formed. Then, the copper wire light strip is conveyed to the adjacent wire pulling station. The connecting rod device IV 502 on the wire pulling device 50 drives the wire pulling clamp 501 to move towards the conveyor table 1. The cylinder controls the wire pulling clamp 501 to be in the open state. When the preliminary U-shaped copper wire light strip is in the wire pulling clamp, the wire pulling clamp 501 closes and is driven to retract by the connecting rod device IV 502, completing the wire pulling. This ensures that the length and shape of the preliminary U-shaped copper wire light strip are basically consistent.

[0037] The U-shaped copper wire light strip 8 is intermittently conveyed forward by the conveyor table 1. When it reaches the tightening station, the wire-organizing device 20, driven by the linkage device II 202 and the cam 5, moves the wire-organizing clamp 201 toward the U-shaped copper wire light strip 8. At the same time, the wire-organizing clamp 201 opens under the drive of the cylinder to further organize the U-shaped copper wire light strip 8. While the wire-organizing clamp 201 is organizing, the wire-twisting device 10, driven by the linkage device I 103 and the cam 5, moves the wire-twisting clamp 101 toward the U-shaped copper wire light strip 8. Initially, the wire-twisting clamp 101 is opened by the drive cylinder. After reaching the designated position, the wire-twisting clamp 101 closes and begins to retract. The cable clamp 201 closes, and the longitudinal cylinder 203 drives the cable clamp 201 to move slightly upward. The limiting device 30 drives the limiting piece 301 to move towards the U-shaped copper wire light strip 8 through the connecting rod device 302. The limiting piece 301 is inserted into the opening of the U-shaped copper wire light strip 8 slightly inside. The wire twisting clamp 101 begins to rotate and tighten the U-shaped copper wire light strip 8 until it is tightened to the position where the limiting piece 301 stops. When the U-shaped copper wire light strip 8 comes into contact with the limiting piece 301 after being twisted and tightened, the twisting action is completed. The cable clamp 201, the limiting piece 301 and the wire twisting clamp 101 each return to their initial positions to prepare for twisting the next U-shaped copper wire light strip 8 that is delivered. This process is repeated in sequence.

[0038] The twisted copper wire light strip continues to be conveyed to the take-up drum 904, where it is wound up until the entire coil of copper wire light strip is twisted.

[0039] Example 2

[0040] like Figures 8-12 As shown, in order to achieve the double-sided twisting of the copper wire light strip, the final result is a double-sided "firecracker" light, as shown in the image. Figure 11As shown, the following improvements are made based on Embodiment 1: A copper wire lamp twisting mechanism includes a conveyor table 1 for conveying copper wire lamp strips. The conveyor table 1 is arranged in a circular shape and is driven by a conveyor motor 2. Several spacer bars 6 are installed on the conveyor table 1. Copper wire lamp strips 7 are arranged on the spacer bars 6 and conveyed to various processing stations for processing. The mechanism also includes a twisting device and a wire organizing device. The twisting device 10 and the wire organizing device 20 are combined and arranged in two sets on the conveyor table 1. The twisting device 10B and the wire organizing device 20B in the second set are combined with the twisting device 10B and the wire organizing device 20B in the adjacent first set. The devices 20 are staggered to complete the twisting of the double-sided firecracker pattern. Each set of twisting and wire organizing devices is equipped with a limit device, a pusher device, and a puller device. For example, the second set of pusher and puller devices are arranged opposite each other on both sides of the conveyor 1 and are located at the front of the conveyor 1, adjacent to the first set of pusher devices 40 and puller devices 50. The second set of puller devices and the second set of twisting devices are located on the same side of the conveyor 1. That is, the second set of pusher and puller devices is also staggered with the first set of pusher devices 40 and puller devices 50, realizing the initial forming of the double-sided straightened U-shaped copper wire light strip 8.

[0041] The second set of limiting devices 30B is also located on the same side as the cable management device 20B in the second set. The second set of limiting devices 30B is provided with a limiting piece 301B and a connecting rod device or cylinder for driving the limiting piece to move axially. The limiting piece is on the same axis as the twisting clamp 101B and the cable management clamp 201B in the second set. When the twisting clamp 101B pulls the copper wire light strip, the limiting piece 301B moves toward the twisting clamp 101B. At this time, the limiting piece 301B is inserted into the opening of the U-shaped copper wire light strip. The twisting clamp 101B begins to rotate and tighten the U-shaped copper wire light strip. When it is tightened to the position where the limiting piece 301B stops and contacts the limiting piece, the tightening action is completed. The limiting piece and the twisting clamp each return to their initial positions.

[0042] The second set of wire twisting device 10B and wire organizing device 20B are also mounted opposite each other on both sides of the conveyor table via support frames. Their height is maintained above the conveyor table 1, and they operate on the copper wire LED strips between adjacent spacer bars 6. The two devices work together to complete the wire twisting process. The end of the wire twisting device 10B is equipped with a wire twisting clamp 101B that rotates via a rotary motor and can be opened and closed. A drive cylinder is installed at the tail of the wire twisting clamp 101B, controlling its opening and closing to clamp the copper wire LED strip and complete the twisting process through its own rotation. The end of the wire organizing device 20B is equipped with an openable wire organizing clamp. 201B, the wire guide clamp is also driven by a cylinder. Before the wire twisting clamp twists the wire, the wire guide clamp completes the combing of the copper wire LED strip. The wire twisting clamp and the wire guide clamp are on the same axis. Under the action of their respective drive devices, they move back and forth in the axial direction. That is, the wire guide clamp moves towards the wire twisting clamp to complete the combing of the copper wire LED strip, and then retracts to prepare to comb the next section of the copper wire LED strip. After the wire guide clamp completes the combing, the wire twisting clamp moves towards the wire guide clamp in an open form. After reaching the position, it closes, and the copper wire LED strip is between the wire twisting clamps. Then it retracts, pulls the copper wire LED strip, and begins to rotate itself, driving the section of the copper wire LED strip to rotate, thus completing the twisting.

[0043] The working principle of the double-sided twisting is the same as in Example 1, ultimately twisting it into the shape of a double-sided "firecracker" lamp, as shown below. Figure 12 As shown.

[0044] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
