Description

Technical Field

[0001] The invention relates to the field of motor coil processing and manufacturing equipment, in particular to a taping head for an automatic white cloth tape taping machine. Background Art

[0002] In the manufacturing of some motor stator and rotor coils, some types of coils are narrow and flat. The coil is annular as a whole, with the nose ends at both ends roughly semi-circular, and a long straight line segment in the middle. The distance (span) between the two opposite straight lines is small. You can refer to Fig.11 When taping this type of coil, the general taping head is difficult to adapt to the taping of narrow span coils. In addition, since the straight section of the coil is long, it is necessary to improve the efficiency of taping as much as possible while ensuring the overlap rate, and it also puts forward higher requirements for the ability of the taping head to store the insulating white cloth tape.

[0003] Through searching, some technical documents about motor coil taping heads or taping equipment are disclosed in the prior art. For example, the utility model authorization announcement document with the publication number "CN205911139U" and the name "A new taping ring for annular transformer taping machine". A new taping ring for annular transformer taping machine is disclosed, including a taping ring body, the taping ring body includes an inner ring and an outer ring, the inner ring and the outer ring are fixed by a number of connecting blocks arranged between the inner ring and the outer ring, and rollers are fixed between the inner ring and the outer ring at intervals through bearings, the thickness of the inner ring is greater than the thickness of the outer ring, and an inner gear ring is provided on the inner diameter of the inner ring. This comparative document is used for taping transformer coils. Since it only proposes corresponding improvements for the taping ring in the taping head, no relevant technical solutions are proposed for the taping head.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] A taping head for an automatic white cloth tape taping machine comprises a rotating seat assembly 1, a taping head lower assembly 2 is mounted on the rotating seat assembly 1, a taping head upper assembly 3 is hingedly connected to one end of the taping head lower assembly 2, and also comprises a taping ring 4, the taping ring 4 is divided into an upper taping ring 41 located in the taping head upper assembly 3 and a lower taping ring 42 located in the taping head lower assembly 2, the taping head upper assembly 3 can be flipped relative to the taping head lower assembly 2 to open and close the taping ring 4; the rotating seat assembly 1 drives the taping head lower assembly 2 to rotate through a rotating mechanism.

[0019] like Figure 1 to Figure 3 As shown, the taping head is suitable for a white cloth tape taping machine. Since the upper component 3 of the taping head can be flipped relative to the lower component 2 of the taping head to open and close the taping ring 4, it will be very easy to load and unload the coil when taping. When taping, the taping ring 4 is completely closed, and the coil passes through the area S0 in the middle of the taping ring 4. The taping ring 4 can be wound and taped by cooperating with the movement of the coil during rotation. During operation, the closed taping ring 4 can have a better taping speed, and the taping ring 4 can also store more insulating white cloth tape. When the taping head needs to tap the arc area at the end of the coil, the rotating seat component 1 can be used to drive the lower component 2 of the taping head to rotate, thereby driving the entire taping ring 4 to rotate, and the center of the rotation is consistent with the arc area at the end of the coil, so as to ensure that the center of the taping ring 4 always moves along the arc area at the end of the coil when taping. After the upper component 3 of the taping head is flipped relative to the lower component 2 of the taping head, only the taping ring 4 is closed, so one end of the upper taping ring 41 and the lower taping ring 42 can enter the coil span, wrapping the single-sided straight line segment to the area S0 in the middle of the taping ring 4, and then performing a rotational wrapping operation on the straight line segment and the nose end arc segment.

[0020] In a more preferred embodiment, the upper assembly 3 of the taping head includes a flip frame 31, and the lower assembly 2 of the taping head includes a flip seat 21. When the flip frame 31 flips relative to the flip seat 21 with the flip axis 32 as the axis, a first locking member is connected to the flip frame 31 and the flip seat 21 to limit the flipping of the flip frame 31 relative to the flip seat 21. Since a relatively stable closed state needs to be maintained when the strap ring 4 is closed during operation, the upper assembly 3 of the taping head cannot be opened relative to the lower assembly 2 of the taping head due to external factors. Therefore, in this embodiment, a first locking member is provided to limit the flipping of the flip frame 31 relative to the flip seat 21.

[0021] Specifically, Figure 4 and Figure 7As shown. There is an arcuate adjacent surface 33 between the flip seat 21 and the flip frame 31, and also includes a locking rod 34, which can penetrate the arcuate adjacent surface 33 to limit the flip frame 31 from flipping relative to the flip seat 21. In this embodiment, one end of the flip frame 31 is an arcuate connecting ear, and the flip seat 21 also has an upwardly extending connecting ear, and the flip seat 21 also has an arcuate seat 211 that matches the arcuate connecting ear of the flip frame 31, and the upper surface of the arcuate seat 211 is adjacent to the arcuate connecting ear of the flip frame 31 to form an arcuate adjacent surface 33. After the locking rod 34 penetrates the flip shaft 32 from the top of the flip frame 31, it can continue to extend through the arcuate adjacent surface 33 and then enter the interior of the arcuate seat 211, thereby locking and fixing the flip frame 31 and the flip seat 21 at the hinge axis to prevent the flip frame 31 and the flip seat 21 from flipping and separating during the strapping operation. In this embodiment, one end of the locking rod 34 has a thread, the arc seat 211 has a matching threaded hole, and the other end of the locking rod 34 has a hand wheel 341 for rotating the locking rod 34 to unlock or lock the flip frame 31 and the flip seat 21.

[0022] In the above embodiment, the hinged ends of the flip frame 31 and the flip seat 21 are locked and fixed, which can prevent the flip frame 31 and the flip seat 21 from separating to a certain extent. If the opposite end of the hinged end is further locked and fixed, a more reliable locking effect can be achieved. Therefore, in a more preferred embodiment, a second locking member is further provided at the ends of the upper and lower strap rings 41 and 42 to limit the relative separation of the upper and lower strap rings 41 and 42.

[0023] For details, please refer to Figure 4 , Figure 5 and Figure 8 , one side of the flip frame 31 is connected to an upper support plate 35, the flip seat 21 is connected to the lower support plate 22, one side of the lower support plate 22 is connected to the lower support plate 23, the upper tape ring 41 is located between the upper support plate 35 and the flip frame 31 and both ends are exposed, and the lower tape ring 42 is located between the lower support plate 22 and the lower support plate 23 and both ends are exposed. In this way, after the flip frame 31 is flipped into place relative to the flip seat 21, the upper tape ring 41 and the lower tape ring 42 are closed, but the aforementioned support plates will not be closed and still have a certain distance, so that the present tape head can extend one end of the closed tape ring 4 into the interior of the annular coil, thereby realizing coil tape wrapping with a smaller span. It should be noted that a driving device for driving the tape ring 4 to rotate is installed on the lower support plate 23, which is irrelevant to the innovative point of the present invention and will not be repeated here.

[0024] The locking plate 36 has a pair of ends respectively fixedly connected to the upper support plate 35 and the flip frame plate 31. The locking plate 36 is provided with a locking groove 361. A locking block 24 is provided at one end of the lower support plate 22 and the lower support plate 23. The locking block 24 can be embedded in the locking groove 361 to limit the relative separation of the upper belt wrapping ring 41 and the lower belt wrapping ring 42. In this embodiment, the locking block 24 is connected to a locking cylinder 241, and the locking cylinder 241 is installed on a cylinder seat 242. The cylinder seat 242 is connected to the ends of the lower support plate 22 and the lower support plate 23. Driving the locking cylinder 241 can embed the locking block 24 into the locking groove 361 to lock the upper belt wrapping ring 41 and the lower belt wrapping ring 42.

[0025] In a more preferred embodiment, Figure 5 As shown. A constant tension mechanism 5 is also connected to the upper part of the upper wrapping ring 41, the flip frame 31 and the upper support plate 35. The constant tension mechanism includes a pressure plate seat 51 hinged at one end of the flip frame 31. One end of the pressure plate seat 51 is connected to the pressure plate 52 and the other end is connected to the telescopic rod 54 of the first cylinder 53. The first cylinder 53 drives the pressure plate seat 51 to swing and drives the pressure plate 52 to swing to adjust the tension. During the wrapping operation, the insulating white cloth tape will enter the flip frame 31 from the external material tray and finally enter the wrapping ring 4. If a larger tension is required, the first cylinder 53 can be adjusted to push the pressure plate seat 51 to press the pressure plate 52 downward, thereby compressing the insulating white cloth tape to provide a larger tension, and vice versa.

[0026] In a more preferred embodiment, Figure 6 As shown. Since the span of the coil varies with different models, when taping the arc of the coil end, it is necessary to adjust the lateral position of the taping head to adapt to different models of coils, so that the center of the taping ring 4 and the arc area of ​​the coil end can match. Therefore, the rotating seat assembly 1 includes a rotating base plate 11, a guide rail 12 is installed on the rotating base plate 11, a guide rail mounting plate 13 is installed on the guide rail 12, and the guide rail mounting plate 13 carries the taping head upper assembly 3; a rack 14 is also installed on the guide rail mounting plate 13, and a gear assembly 15 is installed on the rotating base plate 11. The gear assembly 15 and the rack 14 are engaged to drive the guide rail mounting plate to translate along the guide rail 12. The gear assembly 15 includes a driving motor 151, a gear 153 and a motor mounting seat 152. A limit block 16 is also installed on the guide rail mounting plate 13 to limit the translation of the guide rail mounting plate 13.

[0027] In a more preferred embodiment, at least three centering pressure wheels 25 are connected between the upper support plate 35 and the flip frame plate 31 and between the lower support plate 22 and the lower support plate 23, and the outer surface of the centering pressure wheel 25 contacts the outer surface of the upper and lower wrapping rings 41 and 42. In this embodiment, the centering pressure wheel 25 uses its friction and support force to center the upper and lower wrapping rings 41 and 42, so that after flipping and opening and closing, the upper and lower wrapping rings 41 and 42 can still be accurately aligned to form a closed wrapping ring 4. In this embodiment, the centering pressure wheels 25 are preferably distributed symmetrically along the center of the wrapping ring 4, such as Figure 3 As shown, the four centering pressure wheels 25 are divided into two groups and are respectively located between the upper bracket plate 35 and the turning frame plate 31 and between the lower support plate 22 and the lower bracket plate 23 .

[0028] In a more preferred embodiment, Fig.10 and Figure 3 As shown. Since the weight of the upper assembly 3 on the taping head is relatively large, it will be laborious to manually flip open the upper assembly 3 on the taping head. Therefore, an armrest seat 37 is connected to the side of the upper support plate 35 and the flip frame plate 31, and an armrest ring 38 is fixed through the armrest seat 37. A tension spring 26 is also connected between the flip seat 21 and the flip frame plate 31. The taping head assembly 3 can be easily flipped open by the force of the armrest and the tension spring 26.

[0029] In a more preferred embodiment, Fig. 9 As shown. A band cutting mechanism 6 is also connected to the upper support plate 35 and the flip frame plate 31. The band cutting mechanism 6 includes a band cutting drive unit and a band cutting clamp 61. The band cutting drive unit can drive the band cutting clamp 61 to open and close. Specifically, the band cutting drive unit includes a band cutting cylinder 62, and the free end of the band cutting cylinder 62 is hinged to a scissor swing arm 63. The band cutting clamp 61 is installed on a scissor frame 64, and includes a fixed clamp 611 and an opening and closing clamp 612. The fixed clamp 611 is fixedly connected to the scissor frame 64, and the opening and closing clamp 612 is connected through a band cutting rod 65 that runs through the entire scissor frame 64. The other end of the band cutting rod 65 is connected to the scissor swing arm 63. When the band cutting cylinder 62 is actuated, the scissor swing arm 63 is driven to swing, thereby driving the fixed clamp 611 to move toward the opening and closing clamp 612 and close through the rotation of the band cutting rod 65. In order to ensure that the fixing clamp 611 and the opening and closing clamp 612 have a certain clamping force and can fit tightly at one end like a pair of scissors in the open state, a spring 66 is connected between the scissor swing arm 63 and the scissor frame 64. The elastic force of the spring can make one end of the opening and closing clamp 612 fit tightly against the fixing clamp 611 and maintain a certain clamping force when the scissors belt is closed.
