Description

Technical Field

[0001] The present invention relates to the technical field of coil processing, in particular to a coil processing glue dispensing machine. Background Art

[0002] Coil dispensing significantly improves the reliability and life of coils through multiple functions such as physical fixation, electrical insulation, environmental protection and thermal management. It is an indispensable key process in electronic manufacturing.

[0003] In the prior art, a dispensing head can dispense glue on the side of the coil, and by working in conjunction with other external modules, a multi-dimensional dispensing path can be achieved to cover the glue to the outer side of the coil.

[0004] However, this dispensing method also has some problems:

[0005] 1. Usually, dispensing operations can only be performed on a single coil and multiple coils cannot be processed synchronously or simultaneously, which greatly reduces production efficiency;

[0006] Second, during the dispensing process, a fixture is often required to secure the coil. However, the glue can easily penetrate or flow onto the fixture, causing contamination. There is also the risk that the fixture blocks the coil surface where glue is to be applied, leading to ineffective or uneven dispensing.

[0007] 3. The multi-dimensional dispensing path requires the coordinated operation of complex mechanical equipment, which increases the manufacturing cost and also affects the processing efficiency of the annular coil dispensing. Summary of the Invention

[0008] The present invention provides a coil processing glue dispensing machine that can dispense glue to multiple coils simultaneously. Through a single glue dispensing path, glue can be applied to all sides of the coil, thereby improving glue uniformity and reducing manufacturing costs. Furthermore, by clamping the coils without contact, interference with the glue by the fixture is avoided. The specific solution is as follows:

[0009] The coil processing dispensing machine is used for dispensing glue on the outer sides of multiple coils equidistantly integrated on a sheet. The dispensing machine includes a chassis and a machine platform arranged inside the chassis. The axis of each coil on the sheet is perpendicular to the plane of the sheet; the machine platform is also provided with a flip plate, on which a plurality of suction nozzles for adsorbing the sheet are installed; wherein, the flip plate is configured to grab at least one sheet and switch the sheet to a vertical posture before dispensing glue; the machine platform is also provided with a plurality of dispensing heads equidistantly arranged in the vertical direction, and the number of dispensing heads is consistent with the number of coils on a single sheet; wherein, when the flip plate places the sheet in a vertical posture, each of the dispensing heads can be moved horizontally to directly above the corresponding coil, and form a straight dispensing path on the outer side of the coil.

[0010] Furthermore, the dispensing head is arranged as a whole in an inclined manner, with the lower end being adjacent to the flip plate.

[0011] Furthermore, a turntable is installed on the machine, which is placed horizontally and is used to temporarily place the sheets. The top surface of the turntable is equipped with multiple positioning columns for limiting the edges of the sheets, and the end of the positioning columns away from the turntable is tapered.

[0012] Furthermore, a receiving groove is opened in the middle of the flip plate along its length direction, and a floating pressure plate is installed in the receiving groove; a cylinder is installed on the surface of the flip plate opposite to the suction nozzle, and a flattening connecting plate is installed at its output end; a connecting rod is slidably connected to the flip plate, one end of the connecting rod is connected to the flattening connecting plate, and the other end is connected to the floating pressure plate.

[0013] Furthermore, the floating pressure plate is provided with accommodating holes whose number corresponds to the number of coils on the sheet, and each accommodating hole is collinear with the center of the corresponding coil.

[0014] Furthermore, a calibration protrusion is installed in the receiving hole and is colinear with the center of the receiving hole. The protruding portion of the calibration protrusion extends out of the receiving hole and is located outside the floating pressure plate.

[0015] Furthermore, a material rack is provided on the machine platform, and the material rack is used to place a plurality of stacked sheets.

[0016] Furthermore, a liftable support plate is installed on the machine platform, and a through hole for the support plate to pass through is provided at the bottom end of the material rack, and the support plate can lift the material sheet to a predetermined height through the through hole.

[0017] Furthermore, a transverse moving module 1 is installed on the machine platform, a lifting module 1 is installed on the transverse moving module 1, a flip module is installed on the lifting module 1, and the flip plate is connected to the rotating part of the flip module.

[0018] Furthermore, a lifting module 2 is installed on the machine platform, a transverse module 2 is installed on the lifting module 2, and the plurality of dispensing heads are connected to the sliding part of the lifting module 2.

[0019] Compared with the prior art, the present invention can achieve at least the following beneficial effects:

[0020] The device uses a flip plate that works in conjunction with a suction nozzle to grab multiple sheets and flip them to a vertical position, facilitating the subsequent glue dispensing head to continuously dispense glue and act on the top middle position of the outer side of the coil. The coil in this state provides power for the flow of glue, that is, the glue flows along the outer surface of the coil to the lower part on both sides under the action of gravity, evenly covering the entire outer surface of the annular coil, forming an effective coating. At the same time, multiple glue dispensing heads can achieve synchronous glue dispensing of multiple coils on the sheet, greatly improving production efficiency.

[0021] Furthermore, the flip plate and suction nozzle are combined to form an adsorption sheet to fix the workpiece. This ensures that the glue application process only acts on the coil and does not adhere to other components. This avoids the problem of traditional fixtures blocking the coil glue application surface or glue flowing and penetrating into the fixture to contaminate it.

[0022] Secondly, the dispensing path of the dispensing head is a single straight line, which significantly simplifies the equipment structure and avoids the involvement of too much mechanical equipment. It is directly different from the multi-dimensional dispensing method, improving dispensing efficiency while reducing manufacturing costs. The advantage of a single straight line dispensing path is that this design can be used for dispensing coils of different diameters or with diameter errors, and has good adaptability.

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Please refer to Figure 1 and Figure 2As shown, the present invention provides a coil processing glue dispensing machine for dispensing glue on the outer side surfaces of multiple coils 002 equidistantly integrated on a sheet 001. The cross-sectional shape of the wire of the coil 002 can be flat or circular, etc., wherein the wire can be specifically formed by interweaving multiple filaments; any end of each coil 002 is spot-welded to the sheet 001 to form an integral unit containing multiple coils 002. This method facilitates batch processing of coils 002, such as subsequent glue dispensing, curing, packaging, and other process requirements. Compared with the method of processing individual coils 002 one by one, the processing efficiency is significantly improved.

[0047] For this purpose, refer to Figure 5 、 Figure 6 and Figure 7 As shown, the dispensing machine of the present application also includes a chassis 003 and a machine table 004 arranged inside the chassis 003. The central axis of each coil 002 on the sheet 001 is perpendicular to the plane of the sheet 001. The machine table 004 is also provided with a flip plate 300 connected to an external driving component to achieve horizontal movement, lifting and rotation of the flip plate 300. A plurality of suction nozzles 301 for adsorbing the top side of the sheet 001 are installed on the flip plate 300. The plurality of suction nozzles 301 are interconnected and connected through air pipes. An external negative pressure air pump (not shown in the figure, which is a well-known technology and will not be described in detail) is used to form a negative pressure at the suction end of the suction nozzle 301. When the suction nozzle 301 is in contact with the surface of the sheet 001, the sheet 001 can be adsorbed. The configuration of the flip plate 300 is to cooperate with the suction nozzle 301 to form a simultaneous grasping of four sheets 001 as in the present application. The sheet 001 is switched to a vertical posture by rotating the flip plate 300, thereby preparing for the dispensing of glue on the coil 002 on the sheet 001.

[0048] like Figure 9 As shown, the machine 004 of the present application is further provided with a plurality of dispensing heads 302 arranged equidistantly in the vertical direction. The number of the dispensing heads 302 is consistent with the number of the coils 002 on the single piece of material 001. The dispensing heads 302 are respectively connected to an external glue supply device (the glue supply device is not shown in the figure, it is a well-known technology and will not be described in detail), so as to form a supply of medium and low concentration glue. When the flip plate 300 places the material 001 in a vertical position, each dispensing head 302 can be controlled by an external driving component to move horizontally to the top of the corresponding coil 002, and form a single straight dispensing path on the outer surface of the coil 002.

[0049] When using the above solution: Figure 9 、 Figure 10 and Figure 11As shown, when the flip plate 300 grabs multiple pieces of material 001 and flips them to a vertical posture, the material 001 is perpendicular to the horizontal plane as a whole. Subsequently, multiple dispensing heads 302 move horizontally toward the material 001, so that the dispensing heads 302 are located directly above the coil 002 and the outlet is located in the middle of one end edge of the coil 002. The dispensing heads 302 continuously discharge glue and act on the top middle position of the outer side surface of the coil 002. The coil 002 in this state provides power for the flow of glue, that is, the glue flows along the outer surface of the coil 002 to the lower parts on both sides under the action of gravity, and evenly covers the entire outer surface of the annular coil 002, forming an effective covering ( Figure 11 The black arrow in the figure indicates the glue flow path, and the black dot in the middle of the top of the coil 002 indicates the glue dispensing path). At the same time, multiple glue dispensing heads 302 can achieve synchronous glue dispensing of multiple coils 002, greatly improving production efficiency.

[0050] Furthermore, the dispensing path of the present application is a single straight line, which significantly simplifies the equipment structure and avoids the involvement of excessive mechanical equipment. This is directly different from the multi-dimensional dispensing method, improving dispensing efficiency while reducing manufacturing costs. The advantage of the single straight line dispensing path is that this design can be used for dispensing coils with different diameters or with diameter errors, and has good adaptability.

[0051] Secondly, the workpiece is fixed by sucking the sheet 001 with the nozzle 301, so that the glue will only act on the coil 002 during the coating process and will not adhere to other components. This avoids the problem of traditional fixtures blocking the glue application surface of the coil 002 or the glue flowing and penetrating into the fixture to contaminate it.

[0052] At the same time, it should be added that after the coil 002 on the sheet 001 is glued, the flip plate 300 can be driven by an external driving component, and the sheet 001 on the flip plate 300 can be placed on an external conveying device and transferred to the curing equipment; then, the external driving component controls the flip plate 300 and the suction nozzle 301 to grab the next group of sheets 001 to the glue dispensing head 302 for glue dispensing, thereby realizing automatic continuous operation in this reciprocating manner.

[0053] Reference Figure 9 As shown, the dispensing head 302 is tilted as a whole, and the lower end is adjacent to the flip plate 300, so that the dispensing head 302 is in a non-vertical state. The angle between the dispensing head 302 and the horizontal direction is preferably between 15° and 45°, which is conducive to the glue quickly covering the surface of the coil 002 and forming a uniform glue layer;

[0054] And, as Figure 9 and Figure 10 As shown, the inclined dispensing head 302 can easily extend into the gap between the coil 002 and the sheet 001 during the lateral movement, thereby preventing the sheet 001 from interfering with the moving path of the dispensing head 302 .

[0055] Reference Figure 3 and Figure 4 As shown, a transfer table 200 is installed on the machine 004. The transfer table 200 is placed horizontally and is used to temporarily store the falling pieces 001 released from the external transfer gripper device (suction cup gripper, not shown in the figure); at the same time, a plurality of positioning posts 201 are installed on the top surface of the transfer table 200 for limiting the external or internal edges of the pieces 001. The end (top end) of the positioning posts 201 away from the transfer table 200 is tapered.

[0056] When the above solution is used: the external transfer gripper transports the sheet 001 to the designated position above the transfer table 200 and then releases it. The sheet 001 falls lightly into the area surrounded by the positioning columns 201. The conical structure on the top of the positioning columns 201 guides the sheet 001 to perform fine-tuning of its position during the light fall process to ensure that it is accurately positioned on the transfer table 200. At the same time, multiple positioning columns 201 position the sheet 001, laying the foundation for the precise grasping of the flip plate 300 and the suction nozzle 301, thereby ensuring that the subsequent path of the dispensing head 302 accurately corresponds to the middle position of the top of the outer side surface of the coil 002.

[0057] Reference Figure 12 and Figure 10 As shown, a receiving groove 303 is formed in the middle of the flip plate 300 along its length, and a floating pressure plate 304 is installed in the receiving groove 303; a cylinder 305 is installed on the surface of the flip plate 300 opposite the suction nozzle 301, and a flattening connecting plate 306 is installed at the output end of the cylinder 305; a connecting rod 307 is slidably connected to the flip plate 300, one end of the connecting rod 307 is fixedly connected to the flattening connecting plate 306, and the other end slides into the receiving groove 303 and is fixedly connected to the floating pressure plate 304;

[0058] When using the above solution: Figure 12 As shown, before the above-mentioned flip plate 300 and suction nozzle 301 are located just above the transfer table 200 and are ready to grab the material 001, the cylinder 305 can be first extended and retracted. During the process, the output end of the cylinder 305 extends and can drive the floating pressure plate 304 to move down and extend out of the receiving groove 303 by flattening the connecting plate 306 and the connecting rod 307. The floating pressure plate 304 continues to move downward and presses on one end of the coil 002, and the other end of the coil 002 is restricted by the transfer table 200 to form a blockage. In this way, the coil 002 on the material 001 is flattened and shaped, thereby improving the quality of the coil 002 and the quality of subsequent dispensing. Then, as shown in FIG. Figure 9 As shown, the output end of the cylinder 305 returns to its original position, and the floating pressure plate 304 is retracted into the receiving groove 303 on the flip plate 300, so that the floating pressure plate 304 does not contact the end surface of the coil 002. In this way, when the dispensing head 302 dispenses glue, the glue will not contaminate the floating pressure plate 304 and the components on it;

[0059] It needs to be explained that during the forming process of coil 002, one end of the wire will be cut off. During the cutting process, one end of the wire will be pulled, causing the end of the wire to be pulled and deformed, causing this part of the wire turns to warp, while the remaining wire turns are fitted together, or there are cases where the wire turns are not tightly arranged. In order to address this, the above two situations need to be flattened and shaped.

[0060] Reference Figure 12 As shown, when processing the coil 002 installed with a magnetic rod (only the coil without a magnetic rod is shown in the various figures of this application), the end face of the magnetic rod of the coil with the magnetic rod is slightly protruding from the end face of the coil 002. For this reason, in this application, a number of accommodating holes 308 corresponding to the number of coils 002 on the sheet 001 is opened on the floating pressure plate 304. When the flip plate 300 faces the sheet 001 on the turntable 200, each accommodating hole 308 is collinear with the center of the corresponding coil 002, and the aperture of the accommodating hole 308 is consistent with the inner diameter of the coil 002; so that when the floating pressure plate 304 presses down the coil 002, the protruding part of the magnetic rod can be extended into the avoidance space formed by the accommodating hole 308, thereby preventing the magnetic rod from being crushed and damaged, and at the same time avoiding the interference of the protruding part with the shaping action of the floating pressure plate 304 pressing down the coil 002.

[0061] Reference Figure 13 and Figure 14 As shown, each receiving hole 308 is installed with a calibration protrusion 309 collinear with its center. The calibration protrusion 309 is hollow inside and is a closed component as a whole. It can be made of a rubber material such as butyl rubber. The interior is pre-filled with gas to expand and support its initial state. The surface texture is relatively hard, but it can be deformed as a whole under external transient pressure, which is equivalent to the bladder structure in the prior art. At the same time, the convex portion of the calibration protrusion 309 extends out of the receiving hole 308 and is located outside the floating pressure plate 304. When the calibration protrusion 309 is directly above the coil 002, the center of the convex portion of the calibration protrusion 309 is collinear with the center of the coil 002.

[0062] It should be added that after the wire end of coil 002 is welded to sheet 001, due to the angle between the wire end and sheet 001, the coil 002 on sheet 001 may be skewed as a whole after welding (e.g. Figure 14 As shown, at this time, the center line of coil 002 is not perpendicular to the plane of sheet 001), and when the floating pressure plate 304 subsequently squeezes coil 002, it is easy to cause the turns of coil 002 or the turns at a certain location to be misaligned, causing the coil 002 to present a non-columnar twisted shape as a whole. As a result, the dispensing path of the dispensing head 302 cannot cover the top middle position of the outer side surface of coil 002, resulting in the glue not being able to effectively and evenly flow to the lower parts on both sides, resulting in uneven coating, which affects the dispensing quality of coil 002;

[0063] To this end, when the above solution is used: at the initial stage of the floating platen 304 moving downward, the raised portion of the calibration protrusion 309 on the floating platen 304 will first contact and press the top surface of the skewed coil 002, thereby straightening it. After forced straightening, the center line of the coil 002 is perpendicular to the plane of the sheet 001;

[0064] Subsequently, the floating pressure plate 304 can flatten and shape the coil 002 as the cylinder 305 continues to move downward, forcing the coil 002 to be perpendicular to the sheet 001 and cooperating with the floating pressure plate 304 to press downward, thereby improving the shaping effect.

[0065] Moreover, as the floating pressure plate 304 gradually moves downward, the pressure it applies to the calibration protrusion 309 increases, the calibration protrusion 309 deforms as a whole, and expands toward the outside or into the accommodating hole 308, while the protrusion under pressure between the floating pressure plate 304 and the coil 002 becomes flat, and the flat protrusion forms a layer of rubber pad. The advantage of this is that, on the one hand, the rubber pad can buffer the pressure of the floating pressure plate 304 on the coil 002, preventing the cylinder 305 from over-pressing and damaging the coil 002; on the other hand, it can also prevent the floating pressure plate 304 from directly contacting the coil 002, preventing indentations or damage to the surface of the wire on the top of the coil 002.

[0066] Reference Figure 3 and Figure 15 As shown, a material rack 101 is also provided on the machine 004. Two sets of guide pillars are fixedly connected to the top of the material rack 101, which are located at the four corners. Each set of guide pillars consists of two. At least one sheet 001 is placed between the two guide pillars. A guide opening is reserved on the sheet 001 for inserting it into the two guide pillars. The sheet 001 can be inserted between the two guide pillars in sequence by manual or external equipment, thereby realizing stacking and temporary storage of multiple sheets 001 on the material rack 101.

[0067] Then, if Figure 1 and Figure 3 As shown, the operator can first open the door of the chassis 003, and then send the material rack 101 from the outside of the chassis 003 to the designated position on the machine platform 004 through the conveyor belt 100. Then, the external handling module can gradually grab the sheets 001 on the material rack 101 and place them on the transfer table 200. This process is repeated until all the sheets 001 on the material rack 101 are taken out.

[0068] Finally, the empty rack 101 can be pushed to another return conveyor belt 100 by the side push electric push rod on the machine 004 to deliver the empty rack 101 to the outside of the chassis 003, thereby realizing automatic continuous loading and unloading operations in a reciprocating manner.

[0069] Reference Figure 15 and Figure 3As shown, a liftable support plate 103 is installed on the machine 004, and a through-hole 102 is provided at the bottom end of the material rack 101 for the support plate 103 to pass through. After the material rack 101 reaches the designated position on the machine 004, the support plate 103 is driven by components such as an electric push rod installed at the bottom end of the machine 004, so that the support plate 103 can move up through the through-hole 102 to lift the material 001 to a predetermined height. It can be understood that each time a piece of material 001 is grabbed from the material rack 101, the support plate 103 will move up once, and each time the upward movement height is the overall thickness formed by a piece of material 001 + the coil 002, so as to ensure that the material 001 on the uppermost layer of the material rack 101 is at the grabbing position / height of the external handling module, thereby improving processing efficiency;

[0070] After the material piece 001 on the material rack 101 is grabbed, the support plate 103 is controlled by the output end of the external electric push rod to move downward and move out of the pipe opening of the material rack 101. The material rack 101 is pushed sideways by the external drive and moved to another return conveyor belt 100, thereby realizing automatic continuous loading and unloading operations in this reciprocating manner.

[0071] Reference Figure 5 、 Figure 7 and Figure 8 As shown, the external driving components used to control the flip plate 300 of the present application are a lateral movement module 400, a lifting module 401 and a flip module 402; specifically, a lateral movement module 400 is installed on the machine 004, and a lifting module 401 is installed on the lateral movement module 400. The above two modules are similar to components such as slide rails, screw rods, sliders, and motors in the prior art. The lifting module 401 is installed on the slider of the lateral movement module 400 to form a horizontal reciprocating adjustment movement. A flip module 402 is mounted on the slider of the first lifting module 401. The flip module 402 is composed of components similar to those in the prior art, such as a base plate and a rotary motor. The base plate is mounted on the slider of the first lifting module 401 to provide vertical reciprocating adjustment movement. The rotary motor is mounted on the base plate. The flip plate 300 is connected to the output shaft of the rotary motor on the rotating portion of the flip module 402 to achieve horizontal / vertical flip adjustment of the flip plate 300. The aforementioned drive components are well-known in the prior art and will not be described in detail.

[0072] In general, the cooperation of the above three modules is used to realize that the flip plate 300 is located above the transfer table 200, and grabs the sheet 001 from the transfer table 200 through lateral movement and lifting and lowering actions, and then flips the sheet 001 to face and cooperate with the dispensing head 302 to complete the dispensing of the coil 002 on the sheet 001;

[0073] Moreover, after the glue dispensing of the coil 002 on a piece of sheet 001 is completed, the flip plate 300 can be adjusted to move vertically / horizontally through the cooperation of the modules, and the positions of the remaining sheets 001 / coils 002 that have not been glued can be moved to the glue dispensing head 302 to complete the glue dispensing of the coils 002 on the remaining sheets 001, until the glue dispensing of the coils 002 on the multiple (four) sheets 001 grabbed on the flip plate 300 is completed, and finally the multiple sheets 001 on the flip plate 300 are transferred to the curing equipment through the control of each module.

[0074] Reference Figure 6 and Figure 9 As shown, the external driving components used to control the multiple dispensing heads 302 of the present application are a second traverse module 404 and a second lifting module 403; specifically, a second lifting module 403 is also installed on the machine platform 004, and a second traverse module 404 is installed on the second lifting module 403. The above two modules are similar to components such as slide rails, screw rods, sliders, and motors in the prior art. The second traverse module 404 is installed on the slider of the second lifting module 403 to form a reciprocating adjustment movement in the vertical direction. The multiple dispensing heads 302 are connected to the slider of the second lifting module 403 through the mounting plate, thereby forming a reciprocating adjustment movement of the dispensing heads 302 in the horizontal direction. The above driving components are existing well-known technologies and will not be described in detail.

[0075] In general, the cooperation of the above two modules is used to enable the multiple dispensing heads 302 to move toward the coil 002 on the flip plate 300 to dispense glue and move away from the flip plate 300 after dispensing glue.

[0076] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
