Description

Technical Field

[0001] This utility model relates to the field of coil fixing technology, and in particular to a coil coating positioning device. Background Technology

[0002] As a fundamental component in electronic products, such as transformers and inductors, coils require a crucial encapsulation process during manufacturing. By wrapping insulating tape around the wound coil, insulation, protection, and fixation are achieved, directly impacting the final product's electrical performance and reliability.

[0003] In existing overcoating operations, workers typically need to manually place the coils to be processed onto the overcoating machine's worktable. This process not only relies on repetitive manual labor, but in the context of mass production, the simple manual loading and unloading process has become one of the bottlenecks restricting the overall production cycle, making it difficult to improve processing efficiency.

[0004] More importantly, after the coil is placed, reliable positioning and clamping are essential to ensure accuracy during the wrapping process. In traditional processes, this step often requires operators to hold the coil by hand or rely on simple manual clamps for fixation. Hand-holding poses significant safety hazards, as operators' hands are easily entangled or pinched by moving machine parts. Simple manual clamps, on the other hand, cannot guarantee precise and consistent positioning each time, easily leading to slight displacement of the coil during wrapping, causing quality defects such as uneven tape wrapping and inconsistent tightness, severely impacting product yield.

[0005] Therefore, this utility model proposes a coil coating positioning device to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a coil coating positioning device, which aims to improve the problem that some existing coil coating positioning devices rely on manual feeding and positioning.

[0007] This utility model provides a coil coating positioning device, including a coating machine and a feeding mechanism for feeding coils to the coating machine; the feeding mechanism includes a second support, a feeding trough fixed to the second support and a track communicating with the feeding trough; and a clamping mechanism.

[0008] Furthermore, the clamping mechanism is located at the discharge end of the track; the clamping mechanism includes a housing, the top of which has a groove for receiving the coil that slides down from the track; an air pump three is fixedly connected inside the housing, and a pusher head is connected to the output end of the air pump three; a slider is slidably connected inside the groove, and the bottom of the slider abuts against the top of the pusher head; a limit plate is fixed on the inner side of the housing, and a spring for resetting the slider is connected between the slider and the limit plate.

[0009] Preferably, the coil coating positioning device further includes a cutting assembly, which includes a support, an air pump fixed to the support, and a cutter head connected to the output end of the air pump; the support is fixed to the side wall of the coating machine, and the movement direction of the cutter head is perpendicular to the coating surface of the coil.

[0010] Preferably, the feeding mechanism further includes a base plate fixed to the second bracket, a limiting plate rotatably connected to the top of the base plate, and the feeding mechanism further includes a connecting block and an air pump second for driving the limiting plate to rotate, the air pump second being slidably connected to the outside of the connecting block.

[0011] Preferably, the output end of the second air pump is hinged to one end of the limiting plate. The extension and retraction of the second air pump drives the limiting plate to rotate back and forth, so as to achieve quantitative release of the coil in the track.

[0012] Preferably, the feeding trough is inclined along the extension direction of the track, and the height of the feeding trough is higher than that of the track, so that the coil can automatically slide from the feeding trough into the track under the action of gravity.

[0013] Preferably, the top of the slider forms an upwardly convex arc-shaped support surface, which is used to fit against the inner circumferential surface of the coil to provide stable radial support force.

[0014] Preferably, when the pusher moves upward under the three-pronged drive of the air pump, it pushes the slider to overcome the elastic force of the spring and slide along the inner wall of the groove, thereby tightening and fixing the coil in the groove.

[0015] Preferably, the spring is a compression spring, with one end connected to the side wall of the slider and the other end connected to the limiting plate. When the air pump is not working, the spring force causes the slider to return to the bottom of the groove.

[0016] This utility model has the following beneficial effects: 1. This utility model integrates the coil feeding, positioning and clamping, and tape cutting processes into an automated process by setting up a feeding mechanism, clamping mechanism and cutting components that cooperate with each other. This solves the problem of low overall work efficiency caused by the need for manual completion of each process in the prior art, and achieves the technical effect of improving production efficiency and reducing reliance on manual labor.

[0017] 2. This utility model solves the safety hazard of workers having to hold the coil by hand when fixing it, which is caused by a clamping mechanism driven by an air pump to support the coil internally and externally. This achieves the technical effect of improving the safety of equipment operation.

[0018] 3. This utility model achieves quantitative feeding of coils through the limiting plate in the feeding mechanism and uses the clamping mechanism to stably position the coils, which solves the problems of inaccurate coating position and poor product consistency caused by the large randomness of manual positioning in the prior art, and achieves the technical effect of ensuring processing accuracy and improving product qualification rate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Reference Figures 1 to 4This utility model provides a coil coating positioning device, which aims to solve the problems of low efficiency and safety hazards caused by the reliance on manual operation for coil coating feeding, positioning and cutting tape in the prior art, which results in a lack of automated collaborative mechanisms in the structure.

[0023] like Figure 1 As shown, the device includes a coating machine 1, a feeding mechanism 3 for supplying coils to the coating machine 1, a clamping mechanism 4 for clamping and positioning coils, and a cutting assembly 2. The feeding mechanism 3 includes a second support 31, with a feeding trough 32 fixedly connected to the upper part of the second support 31. The discharge port of the feeding trough 32 is connected to a track 33. The feeding mechanism 3 also includes a base plate 35 fixed to the second support 31. A limiting plate 36 is rotatably connected to the top of the base plate 35. A connecting block 37 is fixed to the second support 31. An air pump 34 is slidably connected to the outside of the connecting block 37. The output end of the air pump 34 is drively connected to the limiting plate 36. The clamping mechanism 4 is located at the discharge end of the track 33 and is used to receive the coils that slide out from the track 33. Reference Figure 3 The clamping mechanism 4 includes a housing 41, with a groove 44 on the top of the housing 41. An air pump 42 is fixedly connected inside the housing 41, and a pusher 43 is connected upward to the output end of the air pump 42. A slider 45 is slidably connected inside the groove 44, with the bottom of the slider 45 abutting against the top of the pusher 43. A limit plate 47 is fixed on the inner side of the housing 41. One end of a spring 46 is connected to the slider 45, and the other end is connected to the limit plate 47. The cutting assembly 2 includes a bracket 21, which is fixed to the side wall of the coating machine 1. An air pump 22 is fixed on the top of the bracket 21, and a cutter head 23 is connected to the output end of the air pump 22.

[0024] Reference Figure 3The clamping mechanism 4 has a groove 44 on its top housing 41. The inner cavity of the groove 44 is used to accommodate and initially position the coil conveyed from the feeding mechanism 3. An air pump 3 42 is fixedly connected inside the housing 41. The output end of the air pump 3 42 is connected to a push head 43 that can move up and down. A slider 45 is slidably connected inside the groove 44. The bottom surface of the slider 45 abuts against the top surface of the push head 43 to receive the thrust from the air pump 3 42. The top of the slider 45 forms an upwardly convex arc-shaped support surface. The shape of this arc-shaped support surface is adapted to the inner circumference of the coil, providing a certain support when in contact. Uniform support force; at the same time, a limiting plate 47 is fixed on the inner side wall of the outer shell 41. A spring 46, which serves as a reset element, is connected between the limiting plate 47 and the side wall of the slider 45. This spring 46 is a compression spring. When the air pump 3 42 does not provide thrust, the preload of the spring 46 pulls the slider 45 back to the initial position at the bottom of the slide groove 44. When the air pump 3 42 is working, the push head 43 moves upward, thereby pushing the slider 45 to overcome the elastic force of the spring 46 and slide upward along the inner wall of the slide groove 44. Its arc-shaped support surface then presses against and tightens the inner wall of the coil, thereby firmly fixing the coil in the slide groove 44.

[0025] The device also includes a cutting assembly 2, which includes a bracket 21, an air pump 22, and a cutter head 23. The bracket 21 is fixed to the side wall of the coating machine 1, the air pump 22 is fixed to the top of the bracket 21, and the cutter head 23 is connected to the output end of the air pump 22. The movement direction of the cutter head 23 is perpendicular to the coating surface of the coil and is used to cut the tape after the coil coating operation is completed.

[0026] The feeding mechanism 3 also includes a base plate 35 fixed to the second bracket 31, a limiting plate 36 rotatably connected to the top of the base plate 35 via a rotating shaft, a connecting block 37 fixed to the second bracket 31, and an air pump 34 slidably connected to the outside of the connecting block 37. The output end of the air pump 34 is hinged to one end of the limiting plate 36. Through the reciprocating motion of the air pump 34, the limiting plate 36 is driven to reciprocate around the rotating shaft, thereby realizing the quantitative release of the coil in the track 33.

[0027] Specifically, the feeding trough 32 is inclined along the extension direction of the track 33, and the height of the feeding trough 32 is higher than that of the track 33. Under the action of gravity, the coil can automatically slide from the feeding trough 32 into the track 33 and be arranged sequentially at the limiting plate 36 to wait for release.

[0028] Specifically, spring 46 is a compression spring. One end of spring 46 is connected to the side wall of slider 45, and the other end is connected to limit plate 47. When push head 43 moves upward under the drive of air pump 3 42, it will push slider 45 to overcome the elastic force of spring 46 and slide along the inner wall of slide groove 44. When air pump 3 42 is not working, the elastic force of spring 46 pushes slider 45 back to the bottom of slide groove 44.

[0029] The implementation principle of this application embodiment is as follows: During operation, the coil is placed inside the inclined feeding trough 32, and slides into the track 33 under the action of gravity and is arranged in sequence. Finally, it is blocked by the limiting plate 36 rotatably connected to the top of the base plate 35. The second air pump 34, which is slidably connected to the connecting block 37, is started. The output end of the second air pump 34 drives the limiting plate 36 to rotate, releasing the obstruction of the coil, so that the single coil continues to slide along the track 33 until it falls into the groove 44 of the clamping mechanism 4 set at the end of the track 33. Then the second air pump 34 moves in the opposite direction to reset the limiting plate 36, ready to feed the next coil.

[0030] After the coil enters the slide groove 44, the air pump 42 fixed inside the outer casing 41 starts, and its output end pushes the push head 43 to move upward. The push head 43 then pushes the slider 45 on its top to overcome the elastic force of the spring 46 and slide upward along the inner wall of the slide groove 44. The arc-shaped support surface on the top of the slider 45 contacts and supports the inner wall of the coil, clamping and precisely positioning the coil in the slide groove 44. At this time, the coating machine 1 performs the coating operation on the positioned coil.

[0031] After the coil is coated, the air pump 22 fixed to the top of the bracket 21 starts, driving the cutter head 23 to move downwards to cut the coating tape. Then the cutter head 23 resets. At the same time, the air pump 42 stops working and resets. Under the elastic force of the spring 46, the slider 45 is pulled back to the bottom of the groove 44, releasing the coil from the clamp. The coated coil can be taken out or transferred to the next station. The entire device resets and waits for the next cycle.
