The rubber coating device comprises a machine table, a rubber roll is arranged on the left side of the top end of the machine table, an inductor placing assembly is arranged on the right side of the top end of the machine table, a rubber coating assembly is arranged at the top end of the machine table, and the rubber coating assembly is located over the inductor placing assembly; the left end of the adhesive tape loses limitation at the moment that the adhesive tape is separated from the adhesive roll, and at the moment, the second spring instantly pushes the driving frame to slide down along the supporting frame so that the adhesive tape can be pressed to the fixing piece through the pressing roller; at the moment, the left end of the adhesive tape can be fixed by the pressing roller and the fixing piece, so that the adhesive tape is prevented from being wound on the inductor or other parts rightwards under the action of self distortion; and therefore, the process that the adhesive tape irregularly wound on the inductor needs to be manually taken down and the process that the adhesive tape is wound on other parts and needs to be manually carded is avoided.

Description

Technical Field

[0001] The present invention relates to the technical field of inductor production, and specifically to a rubber coating device and method for an inductor production line. Background Art

[0002] As a key component in electronic components, inductors are widely used in various electronic devices;

[0003] Inductor rubber coating means winding a tape around the outside of the inductor to improve its performance, stability and reliability. However, in actual use, as the rubber coating of multiple inductors is completed, the tape on the film will gradually decrease. When the end of the tape falls off from the film, under the action of the twisting property of the tape itself, it will generate a pull, causing the tape separated from the film to move towards the inductor. As Figure 1 shown, this will cause the scattered tape to adhere to the inductor irregularly, resulting in the rubber coating of the inductor not meeting the normal requirements and producing defective products. This requires manually removing all the tape wound on the inductor and then re-rubber coating after replacing the film. Moreover, the scattered tape will also adhere to other components of the rubber coating device, which also needs to be manually sorted out. And because the length of the tape end and the part located on the inductor is relatively long after the tape is separated from the film, when the tape scatters, it will cause a large amount of waste of the film for this part.

[0004] Based on this, the present invention designs a rubber coating device and method for an inductor production line to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a rubber coating device and method for an inductor production line to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A rubber coating device for an inductor production line, including a machine table. A film is arranged on the left side of the top of the machine table, an inductor placement component is arranged on the right side of the top of the machine table, a rubber coating component is arranged on the top of the machine table, and the rubber coating component is located directly above the inductor placement component. The rubber coating component is used to fix the right end of the tape and press the tape end onto the inductor, and will cut the tape after the tape winding on the inductor is completed. It further includes:

[0007] A guide rail, located between the film and the rubber coating component and fixedly connected to the machine table at the bottom;

[0008] A support frame, sliding inside the guide rail and fixedly connected with a first spring between the inner wall of the guide rail;

[0009] A roller, rotatably arranged on the left side wall of the support frame and in contact with the film;

[0010] The driving frame is slidably connected to the support frame, and a second spring is fixedly connected between the bottom end thereof and the support frame;

[0011] The pressure roller is rotatably connected to the driving frame;

[0012] The fixing member is located directly below the pressure roller and fixedly connected to the support frame. The end of the tape is pulled by the rubber coating assembly between the pressure roller and the fixing member onto the inductor. The pressure roller contacts the top of the tape and applies a downward pressure to the tape through the driving frame and the second spring. The fixing member is located below the tape and does not contact the tape. When the tape is separated from the film roll, the second spring instantaneously pushes the driving frame and the pressure roller downward so that the pressure roller and the fixing member fix the left end of the tape. After the pressure roller contacts the fixing member, the rotational performance of the pressure roller disappears due to the surface friction of the fixing member;

[0013] The distance detection assembly is located on the machine table and is used to release the fixing of the right end of the tape by the rubber coating assembly when it detects that the distance between the left end and the right end of the tape is not sufficient to complete the winding of the inductor.

[0014] As a further solution of the present invention, the rubber coating assembly includes a pressing head. A first cylinder is fixedly connected between the pressing head and the machine table. The bottom end of the pressing head is arc-shaped. A cross plate is slidably connected to the outside of the pressing head. A second cylinder is fixedly connected between the side wall of the pressing head and the cross plate. A third cylinder is fixedly connected to the cross plate. A fixing rod is fixedly connected to the bottom end of the third cylinder. A deformation block is arranged directly above the fixing rod. An arc-shaped groove is arranged at the bottom end of the deformation block. The deformation block is arranged on the cross plate. A fourth cylinder is fixedly connected to the pressing head. A cutting knife is fixedly connected to the bottom of the fourth cylinder.

[0015] As a further solution of the present invention, the distance detection assembly includes a top rod and a positioning rod. The top rod is slidably connected to the support frame. A third spring is fixedly connected between the top rod and the support frame. The positioning rod is slidably connected to the cross plate. A fourth spring is fixedly connected between the positioning rod and the cross plate. The positioning rod is located directly above the deformation block. The deformation block is slidably connected to the cross plate. After the top rod moves to contact the positioning rod, it will push the left end of the positioning rod to move from above the deformation block to the right side.

[0016] As a further solution of the present invention, a rubber layer is adhesively bonded to the arc-shaped groove at the bottom of the deformation block.

[0017] As a further solution of the present invention, the surface of the pressure roller has a small amount of adhesiveness.

[0018] As a further solution of the present invention, the inductor placement assembly includes a turntable. The turntable is rotatably connected to the machine table. A plurality of plug-in ends are rotatably arranged on the turntable. The plurality of plug-in ends are annularly and equidistantly distributed around the center point of the turntable.

[0019] As a further solution of the present invention, the fixing member is arc-shaped.

[0020] A method for encapsulating an inductor production line, the method comprising the following steps:

[0021] Step 1: Complete the connection between the end of the tape and the inductor, the auxiliary before encapsulation, and the cutting after encapsulation through the cooperation of the encapsulation component and the inductor placement component;

[0022] Step 2: Continuously press down the tape by the pressure roller through the second spring. When the tape falls off the film roll, the pressure roller quickly presses down to fix the tape on the fixing member to complete the fixing of the left end of the tape;

[0023] Step 3: After the left end of the tape is fixed, the fixed-distance detection component will detect the effective length of the tape. When the ejector rod contacts the positioning rod, the ejector rod will push the positioning rod to move to the right side of the deformation block, so that the clamping force disappears when the fixing rod clamps the tape;

[0024] Step 4: After Step 3 is completed, the first spring pulls the support frame to slide leftward along the guide rail, and then pulls up the driving frame to take out the waste material.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. In the present invention, at the moment when the tape is separated from the film roll, the left end of the tape loses its restriction. At this time, the second spring will instantaneously push the driving frame to slide down along the support frame to press down the tape onto the fixing member through the pressure roller. At this time, the pressure roller and the fixing member will fix the left end of the tape to prevent the tape from twisting itself and winding to the right onto the inductor or other components, thereby avoiding the need for manual removal of the tape randomly wound on the inductor and the manual combing process required to prevent the tape from winding on other components.

[0027] 2. In the present invention, the fixed-distance detection component can detect the distance of the tape separated from the film roll. When the distance of the tape is not sufficient to complete the distance of the last encapsulation, the encapsulation component will directly release the fixation of the right end of the tape. When the right end of the tape loses its restriction, the first spring quickly drives the support frame to slide leftward along the guide rail, thereby completing the quantitative cutting after the tape is separated from the film roll, and reducing the waste rate of the waste material on the premise of avoiding the random winding caused by the twisting of the tape itself.

[0042] Please refer to Figures 1-12, the present invention provides a technical solution: a rubber coating device for an inductor production line, including a machine table 1, a rubber roll 2 is arranged on the left side of the top of the machine table 1, an inductor placement component 3 is arranged on the right side of the top of the machine table 1, and a rubber coating component 4 is arranged on the top of the machine table 1. The rubber coating component 4 is located directly above the inductor placement component 3. The rubber coating component 4 is used to fix the right end of the tape and press the tape end on the inductor. After the tape winding on the inductor is completed, the tape will be cut. It also includes a guide rail 5, a support frame 6, a roller 8, a driving frame 9, a pressure roller 11, a fixing member 12, and a distance detection component. The guide rail 5 is located between the rubber roll 2 and the rubber coating component 4 and its bottom end is fixedly connected to the machine table 1; the support frame 6 slides inside the guide rail 5 and a first spring 7 is fixedly connected between the support frame 6 and the inner wall of the guide rail 5; the roller 8 is rotatably arranged on the left side wall of the support frame 6 and contacts the rubber roll 2; the driving frame 9 is slidably connected to the support frame 6 and a second spring 10 is fixedly connected between its bottom end and the support frame 6; the pressure roller 11 is rotatably connected to the driving frame 9; the fixing member 12 is located directly below the pressure roller 11 and is fixedly connected to the support frame 6. The end of the tape is pulled by the rubber coating component 4 between the pressure roller 11 and the fixing member 12 onto the inductor. The pressure roller 11 contacts the top of the tape and applies a downward pressure to the tape through the driving frame 9 and the second spring 10. The fixing member 12 is located below the tape and does not contact the tape. When the tape is separated from the rubber roll 2, the second spring 10 instantaneously pushes the driving frame 9 and the pressure roller 11 downward so that the pressure roller 11 and the fixing member 12 fix the left end of the tape. After the pressure roller 11 contacts the fixing member 12, the rotational performance of the pressure roller 11 disappears due to the surface friction of the fixing member 12; the distance detection component is located on the machine table 1 and is used to release the fixing of the right end of the tape by the rubber coating component 4 when it detects that the distance between the left end and the right end of the tape is not sufficient to complete the winding of the inductor.

[0043] As Figures 2-5 shown:

[0044] After the right end of the tape on the rubber roll 2 is pulled out from the rubber roll 2, it first passes between the pressure roller 11 and the fixing member 12. The pressure roller 11 will apply a downward pressing force to the tape. However, since the left and right ends of the tape are fixed by the rubber roll 2 and the rubber coating component 4 respectively, the tape will remain straight without being affected when the pressure roller 11 presses down the tape. Then, the right end of the tape will be restricted directly above the inductor placement component 3 by the rubber coating component 4;

[0045] When encapsulating, the encapsulation component 4 first presses the right end of the tape down onto the inductor placed on the inductor placement component 3. At this time, the right end of the tape will adhere to the inductor. Then, the inductor placement component 3 will drive the inductor to rotate itself to stretch the tape, so that the tape is wound around the inductor to complete encapsulation. When the tape is stretched, it will move to the right and drive the film roll 2 to rotate. At this time, the tape will move downward while keeping in contact with the pressure roller 11 and drive the pressure roller 11 to rotate. After an inductor is encapsulated, the encapsulation component 4 will cut the tape from the left side of the inductor. After cutting, the encapsulation component 4 will fix the right end of the tape and then pull the tape to the right, so that the right end of the tape can be directly above the inductor. At this time, the inductor placement component 3 will rotate and fix at a certain angle to move the subsequent inductor to be encapsulated directly below the encapsulation component 4, and this process will be repeated;

[0046] As the tape is used, the diameter of the film roll 2 will gradually decrease. During the process of the diameter of the film roll 2 decreasing, the first spring 7 continuously stretches the support frame 6, so that the roller 8 continuously contacts the tape on the film roll 2. Furthermore, when the diameter of the film roll 2 decreases, it is ensured that the support frame 6 can continuously be on one side of the film roll 2, so as to ensure that when the tape is separated from the film roll 2, the left end of the tape can be quickly clamped. When the tape on the film roll is used up, the tape will be separated from the film roll 2. Since the pressure roller 11 continuously applies a downward pressure to the tape, when the tape is separated from the film roll 2, the left end of the tape loses its restraint. At this time, the second spring 10 will instantaneously push the drive frame 9 to slide down along the support frame 6 to press the tape down onto the fixing member 12 through the pressure roller 11. When the pressure roller 11 contacts the fixing member 12, the frictional force on the surface of the fixing member 12 can cause the rotational performance of the pressure roller 11 to disappear. Furthermore, after the pressure roller 11 clamps the tape, it will not rotate. At this time, the pressure roller 11 and the fixing member 12 will fix the left end of the tape to prevent the tape from winding to the inductor or other components to the right under the action of its own twist, so as to avoid the process that manual labor is required to remove the tape randomly wound on the inductor and the process of manual combing required when the tape is wound on other components;

[0047] After the pressure roller 11 and the fixing member 12 fix the tape, under the action of the first spring 7, the support frame 6 has a tendency to be stretched to the left, so as to stretch the tape to a straightened state. Then, the inductor is continuously encapsulated. As the encapsulation progresses, the tape will gradually be stretched to the right. At this time, the support frame 6 will also be stretched to the right. And the distance of the tape can be detected through the distance detection component. When the distance of the tape is not enough to complete the distance of the last encapsulation, the encapsulation component 4 will directly release the fixation of the right end of the tape. When the right end of the tape loses its restraint, the first spring 7 quickly drives the support frame 6 to slide to the left along the guide rail 5, so that the shorter tape quickly moves to the right under the premise of ensuring the effective utilization rate of the tape to avoid the tape residue from adhering to the components.

[0048] The rubber-lagging component 4 includes a pressing head 13, a first cylinder 14 is fixedly connected between the pressing head 13 and the machine 1, the bottom end of the pressing head 13 is arc-shaped, a horizontal plate 15 is slidably connected to the outside of the pressing head 13, a second cylinder 16 is fixedly connected between the side wall of the pressing head 13 and the horizontal plate 15, a third cylinder 17 is fixedly connected to the horizontal plate 15, a fixed rod 18 is fixedly connected to the bottom end of the third cylinder 17, a deformation block 19 is arranged directly above the fixed rod 18, an arc-shaped groove is arranged at the bottom end of the deformation block 19, and the deformation block 19 is arranged on the horizontal plate 15, a fourth cylinder 20 is fixedly connected to the pressing head 13, and a cutter 21 is fixedly connected to the bottom of the fourth cylinder 20.

[0049] like Figure 2 , Figures 6-9 As shown:

[0050] When encapsulating the inductor, the first cylinder 14 will first extend, at which time the cross plate 15 and the tape clamped by the deformation block 19 and the fixing rod 18 will directly drop, and the inclined right end of the tape will first contact the inductor and perform a bonding, and then the first cylinder 14 will continue to extend to make the pressure head 13 contact the inductor, and at this time the pressure head 13 will press the right end of the tape down until it is completely bonded to the inductor and fix the right end of the tape, at which point the first cylinder 14 will stop extending, and at this time the third cylinder 17 will extend to drive the fixing The rod 18 is out of contact with the tape, at which time the fixed rod 18 will release the fixation of the tape and drop to the bottom of the tape, and then the second cylinder 16 will extend to push the horizontal plate 15 to move a certain distance to the left, and then the inductor placement component 3 will drive the inductor bonded with the tape to rotate, so that a fixed length of tape is wrapped around the outside of the inductor. After the inductor is coated with glue, the third cylinder 17 will first shorten and drive the fixed rod 18 to clamp the tape at the bottom end of the deformation block 19, and then the fourth cylinder 20 will extend to drive the cutter 21 to cut the tape;

[0051] Since an arc groove is provided at the bottom end of the deformation block 19, the right end of the tape is inclined after the fixing rod 18 clamps the tape to facilitate the subsequent bonding with the inductor. Then the first cylinder 14 is shortened to the limit, and then the second cylinder 16 is shortened to drive the cross plate 15 and the fixing rod 18 to reset to the right. At this time, the tape will be pulled to the right by a fixed distance, and the end of the tape is just above the inductor.

[0052] The fixed-distance detection component includes a push rod 22 and a positioning rod 24. The push rod 22 is slidably connected to the support frame 6, and a third spring 23 is fixedly connected between the push rod 22 and the support frame 6. The positioning rod 24 is slidably connected to the cross plate 15, and a fourth spring 27 is fixedly connected between the positioning rod 24 and the cross plate 15. The positioning rod 24 is located directly above the deformation block 19. The deformation block 19 is slidably connected to the cross plate 15. After the push rod 22 moves into contact with the positioning rod 24, it will push the left end of the positioning rod 24 to move from above the deformation block 19 to the right side.

[0053] As Figures 2-4 , Figures 9-11 shown:

[0054] When the tape separates from the film 2, the pressure roller 11 and the fixing member 12 will instantaneously fix the left end of the tape. If the inductor is in a state of being wrapped with glue when the pressure roller 11 and the fixing member 12 fix the tape, that is, the inductor placement assembly 3 drives the placed inductor 29 to be rotating, then at this time, as the tape is stretched to the right, the pressure roller 11 and the fixing member 12 will also move to the right. If the fixing rod 18 and the deformation block 19 have fixed the tape and are in the process of pulling the tape to the right (i.e., when the second cylinder 16 shortens) when the pressure roller 11 and the fixing member 12 fix the tape, at this time, as the tape is stretched to the right, the pressure roller 11 and the fixing member 12 will also move to the right;

[0055] As Figure 9 and Figure 10 shown, Figure 10 The figure shows a partial view of the positioning rod 24, that is, the part of the positioning rod 24 that can contact the push rod 22. Since both the left and right ends of the tape are fixed, the part fixed by the pressure roller 11 and the fixing member 12 is point a, and the end point (i.e., the right end of the tape) pressed by the pressing head 13 on the inductor is point b. Since a certain amount of tape will be wound around the inductor every time the inductor rotates for glue wrapping, that is, the consumption required for each inductor glue wrapping is n, and n is slightly less than the diameter from point a to the right end of the push rod 22. The total length between point a and point b is m + n + n + n, and the length of m is less than n. The fixed-distance detection component is used to detect the total length between a and b during each glue wrapping, and the detection process is as follows;

[0056] When working in step S1, the first cylinder 14 first extends to lower the right end of the tape until it adheres to the inductor, and then the pressing head 13 presses down the right end of the tape onto the inductor. At this time, the right end of the inductor is fixed. Then, the third cylinder 17 extends to lower the fixing rod 18 to a position where it does not contact the tape. Then, the second cylinder 16 extends to push the cross plate 15 to move leftward by a fixed distance. Then, the inductor placement assembly 3 drives the inductor directly above to rotate. At this time, the tape is stretched and gradually wraps around the inductor. When the inductor has completed the encapsulation, the inductor placement assembly 3 replaces the inductor. Then, the fixing rod 18 shortens to clamp the right end of the tape under the deformation block 19. Then, the cutter 21 cuts the tape and the first cylinder 14 shortens. Then, the second cylinder 16 shortens to drive the cross plate 15 to move rightward. At this time, the right end of the tape, that is, point b, will be directly above the next inductor. At this time, point a and the ejector rod 22 will move rightward by a distance of n synchronously. At this time, the length between a and b is m + n + n;

[0057] When performing the operation in step S2, after the operation is completed, point a and the ejector rod 22 will move rightward by a distance of n again. At this time, the total length between a and b is a + n. Since m is less than n, the length between a and b at this time can only complete the encapsulation of the last inductor;

[0058] During the operation of step S3, after the encapsulation is completed, the distance that the tape is pulled to the right is n. The distance that point a and the ejector rod 22 move to the right is also n. The distance from point a to the right end of the ejector rod 22 is slightly greater than n. Therefore, before point a finishes moving n distance to the right, the right end of the ejector rod 22 will contact the left end face of the right end of the positioning rod 24 and push the positioning rod 24 to slide to the right along the cross plate 15. At this time, the end of the positioning rod 24 that was originally directly above the deformation block 19 will move to one side to the right. At this time, there is no other block above the deformation block 19. When a moves n distance to the right, when the positioning rod 24 cannot continue to move to the right (the sliding distance of the positioning rod 24 is limited), the ejector rod 22 can only slide to the left along the support frame 6 and compress the third spring 23. However, at this time, the left end of the positioning rod 24 will continue to be on the right side of the deformation block 19. Then, when a moves n distance to the right, that is, when the distance between a and b is m, it means that the encapsulation of the inductor for the last time has been completed. After the encapsulation is completed, the third cylinder 17 will shorten to clamp the tape at the bottom of the deformation block 19. However, because the left end of the positioning rod 24 is no longer above the deformation block 19, the block of the positioning rod 24 on the deformation block 19 will disappear at this time. Therefore, when the fixing rod 18 moves upward to fix the tape between the deformation block 19 and the top of the fixing rod 18, it will not be achieved only by the sliding friction between the deformation block 19 and the cross plate 15. Then, when the cutter 21 cuts the tape, after the right end of the tape loses its fixation, the elastic reset of the first spring 7 will quickly pull the support frame 6, the pressure roller 11 and the fixing member 12 to the left, so that the tape residue with a length of m will be directly pulled to the leftmost side, thereby completing the quantitative cutting after the tape is separated from the film roll 2, and reducing the waste rate of the residue on the premise of avoiding the irregular winding caused by the self-twisting of the tape.

[0059] A rubber layer is bonded to the arc-shaped groove at the bottom of the deformation block 19.

[0060] As Figure 7 shown:

[0061] When there is a rubber layer inside the arc-shaped groove, it can improve the friction force when the fixing rod 18 and the deformation block 19 clamp the tape, and improve the stability. The rubber layer is a prior art, so it is not specifically shown in the figure.

[0062] The surface of the pressure roller 11 has a small amount of adhesiveness.

[0063] As Figure 5 shown:

[0064] When the pressure roller 11 has adhesiveness, it can rotate the pressure roller 11 while having a small amount of mutual adhesion with the pressure roller 11 when the tape is stretched to the right. It can position the tape through the adhesiveness on the surface of the pressure roller 11 when the tape is separated from the film roll 2, so as to avoid affecting the encapsulation effect of the inductor when the tape runs off a large range.

[0065] The inductor placement assembly 3 includes a turntable 25 which is rotatably connected to the machine table 1. A plurality of insertion ends 26 are rotatably arranged on the turntable 25, and the plurality of insertion ends 26 are annularly and equidistantly distributed around the center point of the turntable 25.

[0066] As Figure 1 shown:

[0067] The turntable 25 can rotate on its own on the machine table 1, and the insertion ends 26 can rotate on their own on the turntable 25.

[0068] The fixing member 12 is arc-shaped.

[0069] As Figure 5 shown:

[0070] When the fixing member 12 is arc-shaped, it matches the surface of the pressure roller 11, thereby improving the clamping ability.

[0071] As a further solution of the present invention, the fixing member 12 is arc-shaped.

[0072] A rubber coating method for an inductor production line, the method comprising the following steps:

[0073] Step 1: Through the cooperation of the rubber coating assembly 4 and the inductor placement assembly 3, the connection between the end of the tape and the inductor, the assistance before rubber coating, and the cutting after rubber coating are completed;

[0074] Step 2: The pressure roller 11 continuously presses down on the tape through the second spring 10. When the tape falls off the film roll 2, the pressure roller 11 quickly presses down to fix the tape on the fixing member 12 to complete the fixing of the left end of the tape;

[0075] Step 3: After the left end of the tape is fixed, the fixed-distance detection component will detect the effective length of the tape. When the ejector rod 22 contacts the positioning rod 24, the ejector rod 22 pushes the positioning rod 24 to move to the right side of the deformation block 19, so that the clamping force disappears when the fixing rod 18 clamps the tape;

[0076] Step 4: After step 3 ends, the first spring 7 pulls the support frame 6 to slide leftward along the guide rail 5, and then pulls up the driving frame 9 to take out the waste material.
