Description

Technical Field

[0001] This invention relates to the field of coil winding and coating, and more particularly to a coil winding and coating machine. Background Technology

[0002] Currently, the Alpha winding and coating process on the market uses machine winding, and then the coil is manually taken to the coating machine for coating. This process consumes manpower and has problems such as low production capacity. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a coil winding and coating machine that enables fully automated material handling, thus solving the problems of resource waste and low production capacity caused by manual material handling.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a coil winding and coating machine, characterized in that it comprises:

[0005] A winding mechanism includes a guide that winds a wire to define a loop winding position and can switch between a winding state and a split state. The winding state refers to the winding position having a continuous surface on the guide that can be contacted by the wire, while the split state refers to the winding position being formed by an upper and lower part in an up-and-down separation manner.

[0006] The coating mechanism, which moves independently of the winding mechanism, has a front end with an internal auxiliary plate. The coil enters from the outside of the front end and is positioned so that the auxiliary plate is in the direction of coil entry. This is to maintain surface contact between the tape on the auxiliary plate and the coil, so that when the inner and outer rings of the coil rotate alternately, the remaining tape on the auxiliary plate is attached to the surface of the tape to be covered and other areas of the coil corresponding to the tape.

[0007] According to the present invention, the winding mechanism and the coating mechanism that can be used in conjunction with each other restrict the arrangement of the coil. With this arrangement, the winding mechanism and the coating mechanism are linked together. For example, in both the winding and coating processes, no additional operations requiring translation are involved, and the deviation caused by cost and displacement are effectively controlled. In other words, the structure involved in the winding mechanism and the coating mechanism is specifically designed for this arrangement of the coil. In addition to reducing the loss of manual labor, it can also improve the accuracy of the cooperation between the two mechanisms. Attached Figure Description

[0020] according to Figure 1-6 The specific embodiment shown is used for manufacturing coil 5, which is ring-shaped.

[0021] In this specific embodiment, this wire winding and coating machine includes the following components:

[0022] The coating mechanism 4, winding mechanism 3, scissor mechanism 2, and wire pulling and feeding mechanism 1—all these components fully embody the entire manufacturing process of wire from material feeding to finished product output.

[0023] Among the above components, the winding mechanism 3 is mainly used to guide and wind the wire. The coil formed after this winding is in the shape of a pancake. This pancake shape is temporary and requires the coating mechanism 4 to coat the coil 5 with glue to ensure that the shape of the coil 5 can be maintained.

[0024] The scissor mechanism 2 is used to cut the unwound wire between multiple coils 5. The wire pulling and feeding mechanism 1 is used to pull the wire. The number of turns of the coil 5 is limited according to the requirements. For example, if the number of turns of the coil 5 is five, the wire pulling and feeding mechanism 1 controls the length of the wire to be wound within the range that can be wound five times according to the calculation of the host computer. The above number of turns of the coil 5 is only an example and is not intended to limit the scope of the present invention. Four turns, six turns, etc. can be wound depending on the specific situation.

[0025] The coating mechanism 4 and winding mechanism 3 involved in this invention have corresponding restrictive conditions. For example, after the coil 5 is successfully wound, it can only be parallel to the horizontal plane. Therefore, the coating process of the winding mechanism 3 on the coil 5, in which the tape must be arranged longitudinally, is also subject to corresponding restrictions.

[0026] The winding mechanism 3 includes a guide with a winding position for limiting the wire to be wound according to a horizontal plane. This winding position can be a groove around the circumference of the guide, with a continuous surface that the wire can contact. When the wire is wound in the groove, it is limited by the various surfaces in the groove, ensuring that the number of layers between the coils 5 is parallel.

[0027] The coating mechanism 4 is independent of the winding mechanism 3 and has a movable function. It has a front end with a notch, which is C-shaped in this specific embodiment. The gap between the first edge 41 and the second edge 42 on both sides of the notch at the front end allows the coil 5 to enter. The coil 5 enters when the first edge 41 and the second edge 42 completely reach the inner ring surface of the coil 5. Furthermore, the auxiliary plate 43 in the front end can make the adhesive tape on its surface contact the side of the coil 5, so that the adhesive tape and the coil 5 complete the initial connection. The prerequisite for achieving this surface connection is that the auxiliary plate 43 is set in the direction of the coil 5 entering. This setting is such that the setting direction of the auxiliary plate 43 is perpendicular to the horizontal direction of the coil 5, so that when the inner and outer rings of the coil 5 rotate alternately, the remaining adhesive tape on the auxiliary plate 43 is attached to the surface of the adhesive tape to be covered and other areas of the coil 5 corresponding to the adhesive tape.

[0028] It should be noted that the guide has two states: separation and winding. In the winding state, the groove is annular. In the separation state, the groove is formed by the upper and lower parts of the groove. After the tape is attached, the upper part of the coil 5 is separated from the lower part and the coil 5 is removed.

[0029] The upper part and the lower part are respectively the upper pressure head 30 and the lower pressure head 31. The upper surface of the lower pressure head 31 is provided with a support protrusion 32 near its center. When the upper pressure head 30 presses on the lower pressure head 31, the side of the support protrusion 32, the bottom surface of the upper pressure head 30, and the top surface of the upper pressure head 30 form a groove on the guide. Based on the above scheme, it is to ensure that the coil 5 can be smoothly moved out in the subsequent discharge. This discharge method is based on the glue coating process and will not affect the tape on the coil 5.

[0030] Inside the winding mechanism 3, there is also a winding rotation assembly 33 that drives the lower pressure head 31 to rotate. The upper pressure head 30 rotates in response to the rotation of the lower pressure head 31. This winding rotation assembly 33 is used in conjunction with the tape pulling assembly in the coating mechanism 4. Since the coil 5 is ring-shaped, in order to control the tape usage rate and ensure the coating effect, the four areas of the coil 5 are coated. For example, after the first tape application is completed, the tape pulling assembly will introduce new tape onto the auxiliary plate 43. With the rotation assembly rotating 90° each time, this coating method can effectively limit the coil 5 from becoming loose.

[0031] Specifically, the tape-pulling assembly is a pneumatic clamping component with a tape-pulling lifting mechanism. The upper and lower regions of the front end are respectively provided with corresponding open structures. Both of these open structures are close to the two ends of the auxiliary plate 43. The pneumatic clamping component enters from the open structure in the lower region and exits from the open structure in the upper region. During this lifting process, the positional change of the pneumatic clamping component is manifested in the form of linear movement. This linear movement is parallel to the side of the auxiliary plate 43 with the tape.

[0032] As can be seen from the above, the pneumatic clamping component resets after clamping the tape. At this time, the tape enters through the open structure in the upper region and is fixed on the end of the auxiliary plate 43 away from the upper region. After the tape is fixed, the pneumatic clamping component fully exits from the front end.

[0033] The aforementioned auxiliary plate 43 fixes the tape by having an open structure at the front end in the lower region with a suction nozzle around its perimeter. The pneumatic clamping component pulls the tape onto the suction nozzle, which is close to the auxiliary plate 43. When the suction nozzle adsorbs the tape, it is fixed to one end of the auxiliary plate 43.

[0034] Regarding the situation where the auxiliary plate 43 mentioned above rotates alternately in the inner and outer rings of the coil 5, the coating mechanism 4 contains a coating rotation component. Through the coating rotation component, and based on the fact that the front end is C-shaped, a center is constructed in the area between the inner and outer ring surfaces of the front end, and the front end rotates through this center.

[0035] Since the front end is C-shaped, in order to drive the front end to rotate, multiple teeth 47 are provided on the periphery of the front end. The rubber-coated rotating assembly includes a gear set 44, which is used to rotate the front end.

[0036] The tape feeding assembly of the tape feeding mechanism 4 also includes a tape feeding assembly with a tape roll. The tape feeding assembly has a guide channel composed of multiple guide rollers 45. The tape is fed out from the guide channel. In the area between the guide channel and the front end, there is a cutter 46 that can cut the tape. After the tape and the coil 5 have completed the initial connection, the cutter 46 extends outward to cut the tape.

[0037] The winding mechanism 3 guides the wire in two ways: synchronous rotation with the lower pressure head 31 and asynchronous rotation. The synchronous rotation with the lower pressure head 31 is to prevent continuous traction on the wire inside the wire roll during the winding process. The asynchronous rotation with the lower pressure head 31 is to wind part of the wire in the groove so that the wire between the winding mechanism 3 and the wire feeding mechanism 1 is taut.

[0038] The above two synchronous and asynchronous scenarios are implemented through the following specific structure:

[0039] The winding mechanism 3 includes a feeding rotating assembly 35 and a driven rotating component 36. The feeding rotating assembly 35 has a recessed structure on the end corresponding to the upper pressure head 30. The driven rotating component 36 is embedded in the recessed structure and connected to the bearing in the recessed structure. This forms that the rotation of the feeding rotating assembly 35 and the driven rotating component 36 is independent of each other and will not affect each other. The upper pressure head 30 is provided with a positioning post 37. The lower end face of the driven rotating component 36 has a mounting hole, which is engaged and fixed with the positioning post 37.

[0040] Since the wire is inserted into the feeding rotary assembly 35 and emerges from the recessed structure, an auxiliary wheel is provided on the outside of the feeding rotary assembly 35, and the wire is fed outward by the auxiliary wheel.

[0041] To provide a clearer explanation of the invention, the working principle of the invention will now be specifically described in the following manner, in conjunction with the above content:

[0042] The feeding rotary assembly 35 moves towards the downward pressure head 31 via the winding lifting assembly 38 in the winding mechanism 3 until the support protrusion 32 abuts against the upper pressure head 30, forming a groove on the guide. The clamp on the wire pulling and feeding mechanism 1 pulls the wire drawn from the auxiliary wheel outward at a set length, and the spatial position involved in this wire pulling coincides with a portion of the recessed area. The feeding rotary assembly 35 rotates clockwise, causing the wire to wind a certain portion in the groove (the length involved in this portion is less than half the current number of turns of the coil 5) and then stops. The wire pulling and feeding mechanism 1 resets, and the winding rotary assembly 33 rotates clockwise, and the wire is wound into a coil 5 in the groove. The tape pulling assembly in the coating mechanism 4 pulls the tape onto the auxiliary plate 43 and then coats it. Mechanism 4 approaches winding mechanism 3 with its front end aligned with coil 5 until the tape adheres to coil 5. The tape rotating assembly rotates the front end to complete partial tapering of coil 5. Tape wrapping mechanism 4 then resets, allowing coil 5 to exit from the front end. The above action is repeated by rotating coil 5 90° at a time to tape four areas of coil 5. After tapering coil 5, winding lifting assembly 38 resets. A clamping assembly 6 with three-dimensional stroke removes upper pressure head 30 from lower pressure head 31. Wire pulling and feeding mechanism 1 removes coil 5 from lower pressure head 31 (during the middle and later stages of tapering coil 5, wire pulling and feeding mechanism 1 will release the clamping required to pull out the wire). Excess wire on coil 5 is cut by scissor mechanism 2.

[0043] The surface of the pressing head 31 has a cross-shaped clearance groove 3101 that extends to the circumferential surface of the pressing head 31, so that the clamp of the wire feeding mechanism 1 can smoothly clamp the coil 5.

[0044] It should be noted that the auxiliary plate 43 is in close contact with the coil 5 when rotating, and the auxiliary plate 43 will deform. By adopting the above scheme, the tape can be in full contact with the coil 5, avoiding the phenomenon of tape wrinkling. At the same time, at least one set of auxiliary plates 43 is provided, which is arranged in an axially symmetrical manner to provide greater resistance and improve the wrapping strength of the tape on the coil 5.

[0045] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
