Description

Technical Field

[0001] This invention relates to the field of cable winding, and more particularly to a winding machine for winding new energy sandwich coils. Background Technology

[0002] In recent years, new energy electric vehicles have become mainstream. The coil winding methods in new energy electric vehicles are different from the mature coil winding methods on the market. At present, the domestic production of new energy coils is basically done by manual winding, which is time-consuming, labor-intensive, inefficient, and the product consistency is not high, which can easily lead to hidden dangers and vehicle failures. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a winding machine for winding new energy sandwich coils, aiming to solve the problems of low yield and low efficiency caused by manual coil winding.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A winding machine for winding new energy sandwich coils, characterized in that it comprises:

[0006] The fixture has connecting parts at both ends. A robot pulls the coil on the fixture so that the end of the coil bends toward the connecting part.

[0007] The wire-pulling mechanism has a set of reciprocating paddles, and the coil is wound around the surface of the fixture against the side of the paddles;

[0008] The tape-applying mechanism can suspend the tape in a designated area, while the wire-pulling mechanism presses the tape with a coil on the fixture by avoiding a jig.

[0009] The beneficial effects of this invention are as follows:

[0010] A new winding machine was constructed, which includes a jig, a wire-pulling mechanism, a tape-applying mechanism, and a robotic arm mechanism. The robotic arm mechanism pulls the coil and, together with the jig, rotates it to wind the coil onto the jig. At the same time, the wire-pulling mechanism guides the winding of the coil, limiting the spacing between coils and reducing the gaps between them. After the coil is wound, the jig is wrapped with adhesive tape from the tape-applying mechanism. In this way, the goal of replacing manual winding with machinery is achieved, solving the problem of time-consuming and labor-intensive work. Attached Figure Description

[0027] Please see Figure 1-8 As shown, this invention relates to a winding machine for winding new energy sandwich coils, comprising a feeding mechanism 1, a tape-applying mechanism 2, a fixture 3, a wire-picking mechanism 4, a robotic arm mechanism 5, a disassembly mechanism 6, a clamping device 8, and a coil supply device. The feeding mechanism 1 is used to transfer the assembled fixture 3 onto the clamping device 8. The clamping device 8 enables the fixture 3 to rotate along its main shaft and is linked with the robotic arm mechanism 5 and the coil supply device.

[0028] First, the robotic arm mechanism 5 leads one end of the coil from the coil supply device to the connecting part of the fixture 3. After the connecting part fixes one end of the coil, the clamping device 8 drives the rotating spindle to rotate, thereby driving the fixture 3 connected to the rotating spindle, so that the coil is wound on the surface of the fixture 3. At the same time, the wire pulling mechanism 4 is used to assist the coil winding on the surface of the fixture 3, so that the coils are in close contact. After the winding is completed, the fixture 3 falls into the disassembly mechanism 6, and the disassembly mechanism 6 disassembles the mold 38 on the fixture 3.

[0029] The feeding mechanism 1 is used in conjunction with the central push rod mechanism 7. The feeding mechanism 1 includes a feeding assembly, which is composed of multiple linear sliding components. The output end of the feeding assembly is connected to a feeding base plate 100, which is used to provide each fixture 3 into the clamping device 8. The central push rod mechanism 7 includes a follower, which is used in conjunction with the clamping device 8 to satisfy the condition for the fixture 3 to rotate.

[0030] The driven member is a driven shaft. The clamping device 8 is used to clamp the fixture 3, forcing the fixture 3 to rotate. The driven shaft is driven by the other end of the fixture 3, so that the fixture 3 can rotate smoothly when it has sufficient support.

[0031] It should be noted that the driven shaft is provided with a first connecting part 300, which is the same part as the second connecting part 301 provided at any end of the fixture 3. The end of the fixture 3 that lacks the second connecting part 301 is inserted into the driven shaft.

[0032] The connecting part is to ensure that the coil is restricted on the connecting part. Specifically, the connecting part is provided with a wire clamp. The coil is fixed on the connecting part by the wire clamp so that the coil is pulled and wound on the coil. The centrifugal force formed at the end of the coil after the follower fixture 3 rotates is offset by the wire clamp.

[0033] The fixture 3 has a partition 31 that divides its surface into multiple regions. The coil is wound in two adjacent regions for one cycle, and is cut off by the shearing part included in the robot at the end of each cycle.

[0034] The first connecting part 300 and the second connecting part 301 each have three wire clips. The number of wire clips is limited. Moreover, the wire clips are distributed on both sides of the connecting part in a staggered manner. This is because the coil wound by this winding method is a semi-finished product and needs to be packaged in batches. At the same time, the end of the coil needs to be exposed outside the packaging so that the yield of the coil can be tested later.

[0035] Specifically, there are two partitions 31, which divide the fixture 3 into three areas. The coil supply device first pulls the coil to the first wire clamp 32 near the first area and clamps it. The coil supply device then moves to the third area, so that the coil is distributed from the first area to the second area and the third area in sequence. Then the clamping device 8 drives the fixture 3 to rotate, so that the coil is wound on the third area.

[0036] After the coil winding in the third region is completed, the robot arm mechanism 5 pulls the coil on the first wire clamp 32 to the second wire clamp 33 in the third region, and extends the coil on the coil supply device from the first region to the second region until the coil is fully wound in the second region. Then, it is clamped by the third wire clamp 34 in the third region and cut by the shearing part.

[0037] The coil cut by the shearing part on the coil supply device is held by the fourth wire clamp 35 on the third region and extends to the first region. The clamping device 8 drives the fixture 3 to rotate, so that the first region is fully wound with coil.

[0038] The robotic arm mechanism 5 pulls the coil on the first clamp 32 to the sixth clamp 37 and the coil on the third clamp 34 to the fifth clamp 36. Another layer of coil is wound on the coil in the second region. The tail of the coil after winding is clamped by the third clamp 34 and cut off by the shearing part.

[0039] The fixture 3 is also fitted with molds 38 adjacent to the partition 31 on both sides. The molds 38 have slots. The coil passes through the slots and is connected to the wire clamp, or the coil passes through the slots after being clamped by the wire clamp. The slots are used to limit the large changes caused by the rotation of the coil.

[0040] The wire-pulling mechanism 4 has a set of reciprocating paddles 41. The coil is wound around the surface of the fixture 3 with the side of the paddles 41 as it rests against the side of the paddles 41. Before the first turn of the coil is wound, the paddles 41 will move to the position of the coil to be wound. The coil will slide down onto the surface of the fixture 3 with the side of the paddles 41 as it is pressed against the side. This cycle can make the coil more tightly wound, with each turn of the coil pressed against the next, so that there are no gaps between the coils.

[0041] It also includes an unlocking mechanism for opening the clamp, which consists of two clamps 39 hinged together. Each clamp 39 is connected to a handle 40, and the handle 40 is connected to the connecting part by a spring. The unlocking mechanism is an unlocking cylinder. By pressing the handle 40 with the unlocking cylinder, the meshing surfaces between the two clamps 39 can be separated.

[0042] It also includes a tape applicator 2, which can suspend the tape in a designated area, and a wire-pulling mechanism 4, which presses the tape with a coil on the fixture 3 by passing through a clearance fixture 3.

[0043] The tape applicator 2 mainly consists of a tape reel 21, a tape winding assembly, a cutting mechanism 22, a pressing mechanism 23, and a pulling mechanism 24. The tape on the tape reel 21 is pulled by the tape winding assembly, causing part of the tape to be exposed outside the tape winding assembly. After clamping the exposed tape, the pulling mechanism 24 pulls the tape out of the tape winding assembly in a movable manner. The tape that is pulled out is parallel to the horizontal plane, and with the rotation of the fixture 3, the tape is applied to the coil and wound. The cutting mechanism 22 cuts off the excess tape, and the pressing mechanism 23 makes the tape on the coil flat.

[0044] The adhesive-pulling mechanism 24 includes a set of clamping blocks 25. One clamping block 25 is driven to rotate by a driving device, while the other clamping block 25 is stationary. The movable clamping block 25 has a protrusion 26, and the stationary clamping block 25 has a groove corresponding to the protrusion 26. The adhesive paper is gripped by the protrusion 26 and the groove, which has the characteristic of excellent clamping effect.

[0045] The tape winding assembly consists of multiple sets of winding wheels 27. In order to adjust the position between the winding wheels 27, the tape winding assembly also includes a positioning element and a sliding element. Some of the winding wheels 27 move synchronously with the sliding element. The sliding element consists of a sliding cylinder 28, a slide rail 29 and a push rod. The slide rail 29 is connected to the push rod. The sliding cylinder 28 pushes the slide rail 29, which can move under the restriction of the positioning element.

[0046] In order to adjust the counter-tension of the tape winding assembly, the tape winding assembly also includes a rotating device (not shown in the figure). The tape winding assembly has a rocker arm 30 inside. One end of the rocker arm 30 has a rocker arm shaft that passes through the push rod and slide rail and is driven by the rotating device. The other end of the rocker arm 30 is connected to the shaft of some or all of the winding wheels. Under the swing of the rocker arm 30, the winding wheel 27 will press the tape.

[0047] The pressing mechanism 23 is a pressure roller that can move toward the coil wrapped with adhesive paper and abut against the adhesive paper.

[0048] It also includes a disassembly mechanism 6, which disassembles the connecting parts at both ends of the fixture 3. The disassembly mechanism 6 includes a cavity and a disassembly cylinder 61. The cavity contains a clamping member 62 that holds the wire clamp. The piston rod of the disassembly cylinder 61 is connected to the clamping member 62. By disassembling the cylinder 61, the mold 38 is withdrawn from both ends of the fixture 3.

[0049] The disassembly mechanism 6 also has the function of shaping the coil, including a set of relatively distributed shaping cylinders 64. The piston rod of the shaping cylinder 64 is connected to a shaping block 63, and a cavity for positioning the fixture is formed between the two shaping blocks 63. The two shaping blocks 63 move closer to each other and change the shape of the coil by squeezing.

[0050] The robotic arm mechanism 5 includes multiple sets of moving components and gripper cylinders, which are used to drive the gripper cylinders and shearing parts to move in multiple directions.
