Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to a pre-coating mechanism. Background Technology

[0002] The manufacturing process of transformers typically includes winding, bushing, and wrapping. Before winding, to ensure the electrical insulation performance, mechanical strength, and structural stability of the coil, the surface of the first end of the wire is usually tightly wrapped with insulating tape. After winding, the end of the wire is wrapped with insulating tape again to ensure the reliability of both ends of the coil and improve safety in electrical applications. In current automated transformer processing equipment, due to the flexibility of the wire itself, the tape lacks continuous radial pressure applied to the wire surface during the wrapping process. This results in insufficient adhesion between the tape and the wire, poor adhesion, and affects the quality of the wrapping. Utility Model Content

During the coating process, the tape is first conveyed by the tape feeding assembly, and the tape is simultaneously clamped and stretched to the coating position by the clamping assembly. Then, when the wire is transported to the coating position, the tape coating assembly drives the tape coating brush to move towards the tape, so that the tape wraps around the surface of the wire. At the same time, when the tape coating brush rotates, the tape is adhered to the wire. After adhesion, the tape is cut and separated by the tape cutting assembly.

[0023] The front-mounted adhesive coating mechanism of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 and Figure 3As shown in the embodiment of this utility model, the pre-coating mechanism includes: a base 10, a glue feeding assembly 20, a clamping assembly 30, a glue wrapping assembly 40, and a glue cutting assembly 50. The base 10 has a support plate that is slidable on the base 10. The glue feeding assembly 20 is disposed on the support plate and is used to guide and convey the adhesive tape 70. The clamping assembly 30 is disposed on the support plate and away from the glue feeding assembly 20, and is movable on the support plate. The glue wrapping assembly 40 is disposed between the clamping assembly 30 and the glue feeding assembly 20. Together with the glue feeding assembly 20 and the clamping assembly 30, a glue-wrapping position is defined for stretching the tape 70, so that the part of the tape 70 that needs to be bonded is within the glue-wrapping position. The glue-wrapping brush 41 of the glue-wrapping assembly 40 can rotate when driven. When the tape 70 is clamped and pulled out by the clamping assembly 30, the glue-wrapping brush 41 is driven to move toward the glue-wrapping position and rotate to wrap the tape 70 tightly onto the wire 80. The glue-cutting assembly 50 is provided in the conveying direction of the tape 70 and is used to cut and separate the tape 70.

[0025] Reference Figure 1 As shown, the glue feeding assembly 20 includes a glue feeding tray 21 and a plurality of guide rollers 22. The glue feeding tray 21 is rotatably mounted on a support plate, and the tape 70 is sleeved on the glue feeding tray 21. The plurality of guide rollers 22 are rotatably spaced on the support plate and can guide the tape 70 from the glue feeding tray 21 to the clamping assembly 30, so that when the tape 70 is clamped and pulled by the clamping assembly 30, it can be guided and conveyed from the glue feeding tray 21 sequentially through each guide roller 22, ensuring smoother conveying of the tape 70.

[0026] Reference Figure 1 and Figure 2 As shown, the clamping assembly 30 includes: a first motor 31, a lead screw 32, a connecting seat 33, a sliding block 34, and a pneumatic gripper 35. The first motor 31 is located on the side of the support plate. The lead screw 32 is connected to the first motor 31 and extends toward the adhesive coating assembly 40, so that the first motor 31 can drive the lead screw 32 to rotate. By threading the connecting seat 33 to the lead screw 32, when the lead screw 32 rotates, the connecting seat 33 is driven by the lead screw 32 to move along the length direction of the lead screw 32. The sliding block 34 is slidably located on the support plate and connected to the connecting seat 33, so that the sliding block 34 can slide on the support plate with the connecting seat 33. By fixing the pneumatic gripper 35 to the sliding block 34, when the sliding block 34 is driven by the first motor 31, the pneumatic gripper 35 is driven to move closer to or away from the adhesive coating assembly 40.

[0027] In this embodiment, when the clamping assembly 30 clamps the tape 70, the first motor 31 drives the lead screw 32 to rotate, causing the connecting seat 33 to move along the length direction of the lead screw 32. At the same time, the sliding seat moves, so that the pneumatic gripper 35 moves toward the adhesive wrapping assembly 40 and clamps the tape 70. After clamping the tape 70, the first motor 31 drives the lead screw 32 to rotate in the opposite direction, thereby moving the pneumatic gripper 35 away from the adhesive wrapping position. This stretches the part of the tape 70 that needs to be glued to the adhesive wrapping position, so that it can be wrapped with adhesive by the adhesive wrapping assembly 40 in the future. The way the tape 70 is pulled is simpler and the degree of automation is stronger.

[0028] Reference Figure 3 and Figure 4 As shown, the adhesive coating assembly 40 includes: a sliding plate 42, a first cylinder 43, a second motor 44, multiple synchronous pulleys 45, a transmission belt 46, and a transmission gear 47. The sliding plate 42 is slidably connected to a slide rail on a support plate via a slider. The first cylinder 43 is located on the support plate and connected to the sliding plate 42, allowing the first cylinder 43 to drive the sliding plate 42 to slide. The second motor 44 is located on the sliding plate 42. Multiple synchronous pulleys 45 are rotatably spaced on the sliding plate 42, and at least one synchronous pulley 45 is connected to the motor shaft of the second motor 44, allowing the second motor 44 to drive at least one synchronous pulley 45 to rotate. The transmission belt 46 is wound around the multiple synchronous pulleys 45 to drive each synchronous pulley 45 to rotate synchronously under the drive of the second motor 44. The transmission gear 47 is located on the outside of the transmission belt 46 and is connected to the transmission belt 46. The adhesive coating brush 41 is connected to the transmission gear 47 and can rotate around the axial direction of the transmission gear 47.

[0029] In this embodiment, when the tape 70 is stretched to the wrapping position and the wire 80 is transported to the wrapping position, the first cylinder 43 drives the sliding plate 42 to move toward the wrapping position. This causes the second motor 44, multiple synchronous pulleys 45, transmission belt 46, transmission gear 47, and wrapping brush 41 to move toward the wrapping position together with the sliding plate 42. When the wrapping brush 41 moves to the wrapping position, since the positions of the wire 80 and the tape 70 are fixed at the wrapping position, the wrapping brush 41 moves toward the wire 80 and the tape 70. When in motion, the wire 80 and the tape 70 can enter the coating brush 41 together. Then, the second motor 44 drives the synchronous pulleys 45 to rotate, and the transmission belt 46 drives the transmission gear 47 to rotate. When the transmission gear 47 rotates, it drives the coating brush 41 to rotate synchronously. The coating brush 41 rotates the tape 70 on the surface of the wire 80 and applies pressure to the tape 70 towards the wire 80, so that the tape 70 is tightly attached to the surface of the wire 80, resulting in a higher degree of adhesion between the tape 70 and the wire 80.

[0030] It is understood that the transmission gear 47 includes: a transmission tooth 471, a positioning rotating part 472, and a notch 473. The transmission gear 47 meshes with the transmission belt 46. The positioning rotating part 472 is rotatably disposed in the sliding plate 42. One side of the positioning rotating part 472 is connected to the transmission tooth 471, and the other side is connected to the adhesive brush 41. The notch 473 extends from the transmission tooth 471 to the positioning rotating part 472 and extends radially into the central axis of the transmission gear 47. The notch 473 also communicates with the adhesive brush 41 along the axial direction of the transmission gear 47.

[0031] In this embodiment, when the drive gear 47 and the adhesive brush 41 move toward the wire 80 and the tape 70, the adhesive brush 41 moves toward the parts of the tape 70 and the wire 80 that need adhesive, and the parts of the wire 80 that do not need adhesive can enter the central shaft of the drive gear 47 through the notch 473. Therefore, when the tape 70 is wrapped tightly around the surface of the wire 80, the wrapping brush 41 can rotate in the circumferential direction of the wire 80, and the notch 473 radially limits the wire 80 to ensure that the wire 80 can remain straight to complete the wrapping action. This ensures that during the wrapping process, the wrapping brush 41 can completely surround and tightly wrap the tape 70 around the surface of the wire 80. Furthermore, the sliding plate 42 has a plurality of positioning wheels 49 surrounding the positioning rotating part 472. Each positioning wheel 49 is rotatably disposed on the sliding plate 42 and abuts against the circumferential surface of the positioning rotating part 472, so that when the transmission gear 47 is driven to rotate, it can be supported by the positioning wheels 49, ensuring that the transmission gear 47 rotates more smoothly.

[0032] Furthermore, by providing teeth 461 on both the inner and outer sides of the transmission belt 46, with the teeth 461 on the inner side of the transmission belt 46 meshing with the limiting gear 48 and multiple synchronous pulleys 45, and the teeth 461 on the outer side of the transmission belt 46 meshing with the transmission gear 47, when the transmission belt 46 is driven by the synchronous pulleys 45, the teeth 461 on the outer side of the transmission belt 46 can drive the transmission gear 47 to rotate synchronously, making the overall structure more compact and simple. As a preferred embodiment, the inner side of the transmission belt 46 is adjustablely provided with a limiting gear 48, which is adjacent to the transmission gear 47 and meshes with the transmission gear 47 on the transmission belt 46. This allows the transmission belt 46 to be clamped by the transmission gear 47 and the limiting gear 48 for transmission, and enables the teeth 461 on the outer side of the transmission belt 46 to mesh tightly with the transmission gear 47, preventing the transmission belt 46 from deviating from the transmission gear 47 due to its own flexibility, thus making the operation more reliable.

[0033] Reference Figure 1 and Figure 5As shown, the tape cutting assembly 50 includes: a guide seat 51, a first sliding rod 52, a second cylinder 53, and a cutting blade 54. The guide seat 51 is fixed to a support plate. The first sliding rod 52 is slidably inserted into the guide seat 51. The second cylinder 53 is disposed on a sliding plate 42 and connected to the first sliding rod 52. The cutting blade 54 is connected to the first sliding rod 52 and is close to the conveying direction of the tape 70. Furthermore, the guide seat 51 is also provided with a second sliding rod 60, which is parallel to the first sliding rod 52 along its length. A pressing plate 61 is provided near the cutting blade 54 on the second sliding rod 60. A baffle 62 is provided on the sliding plate 42 that is close to the pressing plate 61. The pressing plate 61 is driven by the second sliding rod 60 to abut against the baffle 62. The second sliding rod 60 is driven to slide by the third cylinder 63.

[0034] In this embodiment, the tape 70 is guided by multiple guide rollers 22 to the space between the baffle 62 and the pressing plate 61, and close to the blade of the cutting blade 54. After the wire 80 completes the tape wrapping action, the second sliding rod 60 is driven by the third cylinder 63 to move towards the tape 70, so that the pressing plate 61 abuts against the baffle 62 along with the second sliding plate 42, clamping and fixing the tape 70. Since the pulled-out portion of the tape 70 is wrapped tightly on the surface of the wire 80, the second cylinder 53 can drive the first sliding rod 52 to move towards the tape 70, so that the cutting blade 54... 4. Move towards the tape 70 and cut and separate the bonded tape 70. A portion of the tape 70 can be clamped between the pressure plate 61 and the baffle 62. When wrapping the subsequent wire 80 with glue, the drive cutter 54 can be moved away from the tape 70 and moved again by the clamping assembly 30 to a position close to the pressure plate 61 to clamp the tape 70. When the pressure plate 61 and the baffle 62 release the tape 70, the clamping assembly 30 pulls the tape 70 out a portion again to the wrapping position, making the overall automation level stronger.

[0035] The pre-coating mechanism provided in this embodiment can be installed on the winding and sheathing equipment of a transformer via the base 10. During the coating process, the tape 70 is first conveyed by the glue feeding component 20, and the tape 70 is clamped and stretched to the coating position by the clamping component 30. Then, when the wire 80 is transported to the coating position, the coating component 40 drives the coating brush 41 to move toward the tape 70, so that the tape 70 is wrapped around the surface of the wire 80 by the coating brush 41. At the same time, when the coating brush 41 rotates, the tape 70 is coated and adhered to the wire 80. After adhesion, the tape 70 is cut and separated by the glue cutting component 50. Thus, during the coating process, the tape 70 can be continuously subjected to radial pressure by the coating brush 41 on the surface of the wire 80, ensuring a tighter adhesion between the tape 70 and the wire 80, good adhesion, and higher coating quality.
