DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0033] The following is combined with Figure 1 To Attachment Figure 6 And specific embodiments describe the present invention in detail.

[0034] The utility model provides a winding mechanism, which can wind the wires so that the wires are neatly and regularly bundled into a ball. The winding mechanism of the present application is installed on a common frame of the wire winding and tie equipment as a part of the wire winding and tie equipment, and cooperates with other mechanisms of the equipment through mechanical clamps to finally complete the processes of wire feeding, wire winding, and tie-tying, thereby realizing the automated processing of wire winding, reducing labor costs, and improving production efficiency.

[0035] like Figure 1-6 As shown, the present application is illustrated by an example of a junction box with electric wires. The winding mechanism provided in the present application includes a first turntable 1, a second turntable 2 and a diameter-changing disk 3. The second turntable 2 is located above the first turntable 1 and is fixedly connected to the first turntable 1 to realize the synchronous rotation of the first turntable 1 and the second turntable 2; the diameter-changing disk 3 is arranged between the first turntable 1 and the second turntable 2, and the diameter-changing disk 3 can rotate synchronously with the first turntable 1 and the second turntable 2, and can also rotate relative to the first turntable 1 and the second turntable 2. The diameter-changing disk 3 is mainly used to change the coil size of the electric wire and release the electric wire after the coil is completed.

[0036] At least two guide holes 21 are provided on the circumference of the second turntable 2. Optionally, the guide holes 21 can be set as strip-shaped slots and extend radially outward. Correspondingly, a diameter-changing slide groove 31 corresponding to the guide holes 21 is provided on the side of the diameter-changing disk 3 opposite to the second turntable 2. Optionally, the diameter-changing slide groove 31 is a spiral arc groove. A diameter-changing slide rod 32 is movably provided in the guide hole 21. The upper end of the diameter-changing slide rod 32 extends to the top of the second turntable 2. The lower end of the diameter-changing slide rod 32 is connected to the guide hole 21 by a sliding group. Part 4 is connected with a guide slide column 33, and the guide slide column 33 is slidably set in the variable diameter slide groove 31; when the variable diameter disk 3 rotates relative to the first turntable 1 and the second turntable 2, the guide slide column 33 slides in the variable diameter slide groove 31 to change the relative position of the variable diameter slide rod 31, thereby changing the coil diameter; when the variable diameter disk 3 rotates synchronously with the first turntable 1 and the second turntable 2, the position of the guide slide column 33 in the variable diameter slide groove 31 remains unchanged, and the relative position of the variable diameter slide rod 32 remains unchanged, that is, the coil diameter remains unchanged.

[0037] See also Figure 1 and Figure 2 As shown, a positioning fixture 22 is provided on the upper end surface of the second turntable 2, and the positioning fixture 22 is used to fix the junction box, and the wires on the junction box are wound around the variable diameter slide bar 32 in circles. When the size of the wire needs to be adjusted before winding, the variable diameter disk 3 is controlled to rotate a preset number of circles, and the rotation of the variable diameter disk 3 drives the guide slide column 33 to slide outward or inward in the variable diameter slide groove 31, and then drives the variable diameter slide bar 32 to move radially inward or outward in the guide hole 21 to adjust the diameter of the coil; when the wire needs to be released after winding, the variable diameter disk 3 is controlled to rotate, and the guide slide column 33 is driven to move inward in the variable diameter slide groove 31, and then the radius slide bar 32 is driven to move toward the center of the second turntable 2 in the guide hole 21 to loosen the wire that has been wound, and then the wire that has been wound is transferred to the tie mechanism for tying through a mechanical clamp.

[0038] It should be noted that the present application does not limit the number of guide holes 21 and variable diameter slots 31, and a one-to-one correspondence is sufficient; in some embodiments, the number of guide holes 21 and variable diameter slots 31 is two, and the wire after winding is not round, but can be a long strip, and the wire can be bundled into a set shape with a tie in the middle of the long strip. In some embodiments, refer to Figure 1 , Figure 2 and Figure 6 The number of the guide holes 21 and the diameter-changing slide grooves 31 are both three, so that the wires after winding are in a ring shape, and the wires can be bundled into a common circular shape by applying a plurality of tie ties on the circular wires.

[0039] Specifically, the variable diameter slide bar 32 of the embodiment of the present application is connected to the guide slide column 33 through the sliding assembly 4, and the sliding assembly 4 provides a guide for the sliding of the variable diameter slide bar 32, so that the variable diameter slide bar 32 can slide synchronously and stably. The sliding assembly 4 includes a slide rail 41 and a slider 42 slidably connected to the slide rail 41.

[0040] In some embodiments, see Figure 3 , Figure 4 The slide rail 41 is fixed on the lower surface of the second turntable 2 and is located on both sides of the guide hole 21. The extension direction of the slide rail 41 is the same as the extension direction of the guide hole 21. Correspondingly, the two sliders 42 are connected to the variable diameter slide rod 32 and the guide slide column 33 through the connecting member 43, that is, the variable diameter slide rod 32 is connected to the upper surface of the connecting member 43, the guide slide column 33 is connected to the lower surface of the connecting member 43, and the two sliders 42 are fixed on both sides of the upper surface of the connecting member 43. The variable diameter slide rod 32 moves along the guide hole 21 under the guiding action of the slide rail 41, thereby realizing the guiding action on the movement of the variable diameter slide rod 32.

[0041] In other embodiments, the slider 42 is fixed to the lower end surface of the second turntable 2 and is located on both sides of the guide hole. A slide groove is provided on the slider 42, and the extension direction of the slide groove is the same as the extension direction of the guide hole 21. Correspondingly, the two slide rails 41 are respectively connected to the variable diameter slide rod 32 and the guide slide column 33 through the connecting member 43, that is, the variable diameter slide rod 32 is connected to the upper surface of the connecting member 43, the guide slide column 33 is connected to the lower surface of the connecting member 43, and the two slide rails 41 are fixed to both sides of the upper surface of the connecting member 43. The slide rail 41 is slidably connected in the slide groove on the slider 42, and the variable diameter slide rod 32 moves along the guide hole 21 under the guidance of the slide groove on the slider 42. The present application makes the sliding of the variable diameter slide rod 32 more stable by setting the sliding assembly 4, and can effectively avoid the jamming and loss of the equipment caused by the deviation of the sliding direction of the variable diameter slide rod 32.

[0042] In at least one optional embodiment, the connecting member 43 is connected to the guide slide column 33 through a U-shaped connecting plate 44, and a through hole is provided on the bottom of the groove of the U-shaped connecting plate 44. The guide slide column 33 includes a rolling column 331 and a connecting column 332. The upper part of the connecting column 332 is provided with an external thread. The connecting column 332 is inserted from the bottom of the through hole and extends from the top and is connected by a nut 333. The connecting column 332 is rotatably set in the through hole, and the rolling column 331 is set in the variable diameter slot 31. The rotation of the variable diameter plate 3 can make the rolling column 331 roll in the variable diameter slot 31, thereby improving the smoothness and stability of the movement of the guide slide column 33. In other embodiments, the guide slide column 33 includes a rolling column 331 and a connecting column 332, and the connecting column 332 is fixedly connected in the through hole, and the rolling column 331 rolls relative to the connecting column 332, which can also achieve the above technical effects. Of course, it is not limited to this.

[0043] Specifically, in order to ensure that the wire can be smoothly wound into a coil, a limit block is fixed at the upper end of the variable diameter slide bar 32, and the limit block has a limit groove, and the open end of the limit groove faces the outer edge of the second rotary disk 2. Optionally, the limit block is a C-shaped limit block 34, and the open end of the C-shaped limit block 34 faces the outer edge of the second rotary disk 2, and the wire is wound into a coil in the C-shaped limit block 34. Optionally, a partition 341 is provided in the C-shaped limit block 34, and the partition 341 separates the C-shaped groove of the C-shaped limit block 34 into two upper and lower grooves. The purpose of providing the partition 341 is to enable the wire to be wound into at least two circles at the same diameter, so as to avoid the wire diameter after winding being too large and the thickness being too small, which is not conducive to the cable tie.

[0044] Specifically, in some embodiments, see Figure 5 At least one positioning fixture 22 is provided on the second turntable 2.

The clamping members are used to clamp the junction box and fix the junction box. At least two pads 222 are provided on the side of the clamping members. At least two pads 222 are respectively located on both sides of the two clamping members. The pads 222 are used to support the junction box and ensure the stability of the junction box. The clamping members clamp the junction box between the pads 222 to prevent the junction box from moving during the subsequent winding process. Optionally, the first driving member 221 of the present application is a clamping claw cylinder, and the relative opening and closing of the clamping members is achieved by the clamping claw cylinder.

[0045] In at least one optional embodiment, there are two positioning clamps 22 on the second turntable 2, one of the positioning clamps 22 makes the wire wind around the diameter-changing slide bar 32 clockwise, and the other positioning clamp 22 makes the wire wind around the diameter-changing slide bar 32 counterclockwise. The positive terminal box and the negative terminal box can be installed on the second turntable 2 at the same time, and clockwise winding and counterclockwise winding can be realized, which has a wider range of applications and can meet 24-hour non-stop operation.

[0046] Specifically, in some embodiments, a sensor assembly 5 is provided below the second rotating disk 2, and the sensor assembly 5 is provided at the outer edge of the variable diameter disk 3, and is used to position the variable diameter disk 3, control the number of rotations of the variable diameter disk 3, and thus adjust the position of the variable diameter slide bar 32. Optionally, the sensor assembly includes a photoelectric sensor, an angle sensor, or a laser sensor facing the outer edge of the variable diameter disk 3, but is not limited thereto; in this embodiment, considering the cost factor, a photoelectric sensor is preferably used, and the model of the photoelectric sensor is EE-SX672.

[0047] Specifically, in this embodiment, the variable diameter disk 3 is installed on the first turntable 1 to realize the synchronous rotation of the variable diameter disk 3, the first turntable 1 and the second turntable 2. Specifically, a motor mounting bracket 11 is fixed on the upper surface of the first turntable 1, and a second driving member 12 is installed on the motor mounting bracket 11.
