Description

Technical Field

[0001] The present invention relates to the technical field of coil processing, and particularly to a coil processing dispenser. Background Art

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

[0003] In the prior art, a dispensing head can perform glue dispensing on the side surface of a coil, and through cooperation with other external modules, a multi-dimensional dispensing path can be achieved to cover the glue on the outer side surface of the coil.

[0004] However, there are also some problems with this dispensing method: First, usually, the dispensing operation can only be performed on a single coil, and multiple coils cannot be processed synchronously / simultaneously, which greatly reduces the production efficiency. Second, during the dispensing process, in order to fix the coil, fixtures are often required, and the glue easily penetrates or flows and adheres to the fixtures, causing contamination; there is also a situation where the fixtures block the surface of the coil that originally needs to be coated with glue, resulting in dispensing failure or unevenness. Third, the multi-dimensional dispensing path requires complex mechanical equipment for collaborative operation, increasing the manufacturing cost and also affecting the processing efficiency of annular coil dispensing. Summary of the Invention

[0005] The present invention provides a coil processing dispenser that can perform simultaneous dispensing on multiple coils, and can achieve the coverage of glue on all sides of the coil through a single dispensing path, improving the glue uniformity and reducing the manufacturing cost, and avoiding the interference of the fixture on the glue through a non-contact clamping method for the coil; the specific solution is as follows: A coil processing dispenser is used for dispensing on the outer side surfaces of multiple coils equidistantly integrated on a wafer. The dispenser includes a chassis and a machine table disposed inside the chassis. The axes of the coils on the wafer are perpendicular to the plane of the wafer; a turning plate is further provided on the machine table, and a plurality of suction nozzles for adsorbing the wafer are installed on the turning plate; wherein, the turning plate is configured to grab at least one wafer and switch the wafer to a vertical posture before dispensing; a plurality of dispensing heads arranged equidistantly in the vertical direction are further provided on the machine table, and the number of dispensing heads is the same as the number of coils on a single wafer; wherein, when the turning plate places the wafer in a vertical posture, each dispensing head can move horizontally to the position directly above the corresponding coil and form a straight dispensing path on the outer side surface of the coil.

[0006] Further, the dispensing head is integrally inclined, and the lower end is adjacent to the direction of the turning plate.

[0007] Further, a transfer table is installed on the machine table. The transfer table is horizontally placed and is used for temporarily placing the wafers. A plurality of positioning posts for restricting the edges of the wafers are installed on the top surface of the transfer table, and one end of the positioning post away from the transfer table is conical.

[0008] Further, a receiving groove is formed in the middle of the turning plate along its length direction, and a floating pressing plate is installed in the receiving groove. A cylinder is installed on one side surface of the turning plate opposite to the suction nozzle, and a flattening connecting plate is installed at the output end thereof. A connecting rod is slidably connected to the turning plate, one end of the connecting rod is connected to the flattening connecting plate, and the other end is connected to the floating pressing plate.

[0009] Further, a plurality of receiving holes corresponding to the number of coils on the wafer are formed in the floating pressing plate, and each receiving hole is collinear with the center of its corresponding coil.

[0010] Further, a calibration protrusion collinear with its center is installed in the receiving hole, and the protruding portion of the calibration protrusion extends out of the receiving hole and is located outside the floating pressing plate.

[0011] Further, a wafer rack is also arranged on the machine table, and the wafer rack is used for placing a plurality of wafers stacked on top of each other.

[0012] Further, a liftable support plate is installed on the machine table. A through hole for the support plate to pass through is provided at the bottom end of the wafer rack, and the support plate can lift the wafer to a predetermined height through the through hole.

[0013] Further, a first horizontal movement module is installed on the machine table. A first lifting module is installed on the first horizontal movement module, and a turning module is installed on the first lifting module. The turning plate is connected to the rotating part of the turning module.

[0014] Further, a second lifting module is also installed on the machine table. A second horizontal movement module is installed on the second lifting module, and a plurality of the dispensing heads are all connected to the sliding part of the second lifting module.

[0015] Compared with the prior art, the present invention can at least achieve the following beneficial effects: Through the arrangement of the turning plate, the turning plate and the suction nozzle cooperate to grab multiple wafers and turn them to a vertical posture, which is convenient for the subsequent dispensing heads to continuously dispense glue and act on the middle position at the top of the outer side of the coil. In this state of the coil, it provides power for the flow of the glue, that is, the glue flows along the outer surface of the coil to the lower parts on both sides under the action of gravity, evenly covering the entire outer side of the annular coil to form an effective coating. At the same time, a plurality of dispensing heads realize synchronous dispensing of multiple coils on the wafer, greatly improving the production efficiency. Furthermore, by using the combination of the flipping plate and the suction nozzle to form a way of adsorbing the workpiece by adsorbing the sheet, the glue coating process will only act on the coil and will not adhere to other components, avoiding the problems that the traditional fixture blocks the glue dispensing surface of the coil or the glue flows and penetrates to contaminate the fixture; Secondly, the glue dispensing path of the glue dispensing head is a single straight line, which significantly simplifies the equipment structure, avoids the intervention of too many mechanical devices, is directly different from the multi-dimensional glue dispensing method, improves the glue dispensing efficiency while reducing the manufacturing cost; moreover, the advantage of the single straight line glue dispensing path is that this design can perform glue dispensing on coils with different diameters or coils with diameter errors, and has good adaptability.

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Please first refer to Figure 1 and Figure 2 As shown, the present invention provides a coil processing and dispensing machine for dispensing on the outer sides of a plurality of coils 002 equidistantly integrated on a material sheet 001. The cross-sectional shape of the coil 002 wire can be flat or circular, etc. Specifically, the wire can be formed by intertwining multiple thin wires; any end wire head of each coil 002 is spot-welded to the material sheet 001 to form an overall unit including a plurality of coils 002. In this way, the present application facilitates the batch processing of the coils 002, such as subsequent dispensing, curing, packaging and other process requirements, and significantly improves the processing efficiency compared with the method of processing a single coil 002 one by one; To this end, as shown in Figure 5 , Figure 6 and Figure 7 , the dispensing machine of the present application further includes a chassis 003 and a machine table 004 disposed inside the chassis 003. The central axes of the coils 002 on the wafer 001 are perpendicular to the plane of the wafer 001; a turnover plate 300 connected to an external driving component is further provided on the machine table 004 to achieve the horizontal movement, lifting and rotation of the turnover plate 300; a plurality of suction nozzles 301 for adsorbing the side edges of the top surface of the wafer 001 are installed on the turnover plate 300. The plurality of suction nozzles 301 are interconnected through air pipes and connected to an external negative pressure air pump (not shown in the figure, which is a well-known technology and will not be elaborated), so that a negative pressure can be formed at the adsorption end of the suction nozzle 301, and when the suction nozzle 301 is in contact with the surface of the wafer 001, the wafer 001 can be adsorbed; wherein, the configuration of the turnover plate 300 is to cooperate with the suction nozzles 301 to simultaneously grab four wafers 001 as in the present application, and the wafers 001 are switched to a vertical posture by the rotation of the turnover plate 300, preparing for the dispensing of the coils 002 on the wafers 001; As Figure 9 shown, a plurality of dispensing heads 302 arranged at equal intervals in the vertical direction are further provided on the machine table 004 of the present application. The number of the dispensing heads 302 is the same as the number of the coils 002 on a single wafer 001. The dispensing heads 302 are respectively connected to an external glue supply device (the glue supply device is not shown in the figure, which is a well-known technology and will not be elaborated) to form the supply of medium-low concentration glue; wherein, when the turnover plate 300 places the wafer 001 in a vertical posture, each dispensing head 302 can be controlled by an external driving component to move horizontally to directly above its corresponding coil 002 and form a single straight dispensing path on the outer side surface of the coil 002; When the above solution is used: as Figure 9 , Figure 10 and Figure 11 shown, when the turnover plate 300 grabs multiple wafers 001 and turns them to a vertical posture, the wafers 001 are perpendicular to the horizontal plane as a whole. Subsequently, the plurality of dispensing heads 302 move horizontally towards the wafers 001. When the dispensing heads 302 are directly above the coils 002 and the outlets are located in the middle of one end edge of the coils 002, the dispensing heads 302 continuously discharge glue and act on the middle position of the top end of the outer side surface of the coils 002. In this state, the coils 002 provide power for the flow of the glue, that is, the glue flows along the outer surface of the coils 002 to the lower parts on both sides under the action of gravity, uniformly covering the entire outer side surface of the annular coils 002 to form an effective coating ( Figure 11 the black arrows in are the glue flow paths, and the black dots in the middle of the top ends of the coils 002 indicate the dispensing paths), and at the same time, the plurality of dispensing heads 302 achieve synchronous dispensing of multiple coils 002, greatly improving the production efficiency; Furthermore, the dispensing path of this application is a single straight line, which significantly simplifies the equipment structure, avoids the intervention of excessive mechanical equipment, is directly different from multi-dimensional dispensing methods, improves the dispensing efficiency, and reduces the manufacturing cost. Moreover, the advantage of the single straight-line dispensing path is that this design can dispense glue for coils 002 with different diameters or coils with diameter errors, and has good adaptability. Secondly, the workpiece is fixed by sucking the sheet 001 with the suction nozzle 301, so that the glue coating process only acts on the coil 002 and will not adhere to other components, avoiding the problems of traditional fixtures blocking the dispensing surface of the coil 002 or the glue flowing and penetrating to contaminate the fixtures. At the same time, it should be added that after the dispensing of the coil 002 on the sheet 001 is completed, the turning plate 300 can be driven by an external driving component, and the sheet 001 on the turning plate 300 is placed on an external conveying device and transferred to a curing device. Subsequently, the external driving component controls the turning plate 300 and the suction nozzle 301 to grab the next sheet 001 to the dispensing head 302 for dispensing, and so on to achieve automated continuous operation.

[0034] Refer to Figure 9 As shown, the dispensing head 302 is integrally inclined, and the lower end is adjacent to the direction of the turning 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. And, as Figure 9 and Figure 10 shown, the inclined dispensing head 302 is convenient for extending into the gap between the coil 002 and the sheet 001 during the transverse movement, avoiding the interference of the sheet 001 on the movement path of the dispensing head 302.

[0035] Refer to Figure 3 and Figure 4 As shown, a transfer table 200 is installed on the machine table 004. The transfer table 200 is horizontally placed and is used for temporarily placing the sheet 001 released from an external transfer gripper device (a suction cup gripper, not shown in the figure). At the same time, a plurality of positioning columns 201 for restricting the outer or inner edges of the sheet 001 are installed on the top surface of the transfer table 200, and the end (top end) of the positioning column 201 away from the transfer table 200 is conical. When the above solution is used: After the external transfer gripper transports the workpiece 001 to a specified position above the transfer table 200 and releases it, the workpiece 001 gently falls into the area surrounded by the positioning posts 201. The conical structure at the top of the positioning post 201 guides the workpiece 001 to perform position fine-tuning during the gentle fall, ensuring its precise landing on the transfer table 200. At the same time, the workpiece 001 is positioned by multiple positioning posts 201, laying a foundation for the precise grasping of the turning plate 300 and the suction nozzle 301, and further ensuring that the path of the subsequent dispensing head 302 accurately corresponds to the middle position at the top of the outer side of the coil 002.

[0036] Refer to Figure 12 and Figure 10 As shown, a receiving groove 303 is formed in the middle of the turning plate 300 along its length direction, and a floating pressing plate 304 is installed in the receiving groove 303; on one side surface of the turning plate 300 opposite to the suction nozzle 301, a cylinder 305 is installed, 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 turning 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 pressing plate 304; When the above solution is used: As Figure 12 shown, before the turning plate 300 and the suction nozzle 301 are located directly above the transfer table 200 and are about to grasp the workpiece 001, the cylinder 305 can first perform telescopic movement. During the process, the output end of the cylinder 305 extends and can drive the floating pressing plate 304 to move downward and extend out of the receiving groove 303 through the flattening connecting plate 306 and the connecting rod 307. The continuous downward movement of the floating pressing plate 304 will press on one end of the coil 002, and the other end of the coil 002 is blocked by the transfer table 200. In this way, the coil 002 on the workpiece 001 is flattened and shaped, improving the quality of the coil 002 and the quality of its subsequent dispensing; Subsequently, as Figure 9 shown, the output end of the cylinder 305 returns, and the floating pressing plate 304 is retracted into the receiving groove 303 on the turning plate 300, so that the floating pressing plate 304 does not contact the end face of the coil 002. In this way, it is ensured that when the subsequent dispensing head 302 dispenses glue, the glue will not contaminate the floating pressing plate 304 and its components; It should be explained that during the forming process of the coil 002, one end of its wire will be cut off. During the cutting process, one end of the wire will be pulled, resulting in the pulling deformation of the end of this wire, causing the warping of this part of the wire turns, while the other wire turns are in contact with each other, or there may be non-closely arranged wire turns. For this, the above two situations need to be flattened and shaped.

[0037] Refer to Figure 12As shown, when processing the coil 002 with a magnetic rod installed (only the coil without a magnetic rod is schematically shown in the attached drawings of this application), the end face of the magnetic rod of the coil with the magnetic rod protrudes slightly from the end face of the coil 002. Therefore, in this application, accommodation holes 308 corresponding to the number of coils 002 on the sheet 001 are provided on the floating pressing plate 304. When the turning plate 300 faces the sheet 001 on the transfer table 200, the center lines of each accommodation hole 308 are collinear with the centers of their respective corresponding coils 002, and the diameter of the accommodation hole 308 is the same as the inner diameter of the coil 002. When the floating pressing plate 304 presses down the coil 002, the protruding part of the magnetic rod can correspondingly extend into the avoidance space formed by the accommodation holes 308, so as to avoid the magnetic rod being crushed or damaged, and at the same time avoid the interference of the protruding part on the shaping action of the floating pressing plate 304 pressing down the coil 002.

[0038] Referring to Figure 13 and Figure 14 As shown, a calibration protrusion 309 collinear with its center is installed in each accommodation hole 308. The calibration protrusion 309 is hollow inside and is an integral closed component, which can be made of rubber materials such as butyl rubber. Gas is pre-filled inside to expand and support its initial state with a relatively hard surface texture, but it can be deformed as a whole under external excessive pressure, which is equivalent to the bladder structure in the prior art. At the same time, the protruding part of the calibration protrusion 309 extends out of the accommodation hole 308 and is located outside the floating pressing plate 304, and when the calibration protrusion 309 is directly above the coil 002, the center of the protruding part of the calibration protrusion 309 is collinear with the center of the coil 002. It should be added that after the wire end of the coil 002 is welded to the sheet 001, due to the angular relationship between the wire end and the sheet 001, there is a situation where the coil 002 on the sheet 001 is skewed as a whole after welding (as Figure 14 shown, at this time, the center line of the coil 002 is not perpendicular to the plane of the sheet 001). When the subsequent floating pressing plate 304 squeezes the coil 002, it is easy to cause misalignment between the turns of the coil 002 or between a certain turn, resulting in the coil 002 as a whole presenting a non-columnar twisted shape, so that the dispensing path of the dispensing head 302 cannot cover the middle position at the top of the outer side of the coil 002, resulting in the glue being unable to flow evenly to the lower sides on both sides effectively, and there is a situation of uneven coating, which affects the dispensing quality of the coil 002. Therefore, when the above solution is used: at the initial stage of the downward movement of the floating pressing plate 304, the protruding part of the calibration protrusion 309 on the floating pressing plate 304 will first contact and squeeze the top surface of the skewed coil 002, and straighten it through extrusion. After being forced to straighten, the center line of the coil 002 is perpendicular to the plane of the sheet 001. Subsequently, as the floating pressing plate 304 continues to move forward with the cylinder 305, it can form a flattening and shaping of the coil 002 during the downward movement. In the form of forcing the coil 002 to be perpendicular to the sheet 001 and cooperating with the downward pressure of the floating pressing plate 304, the shaping effect can be improved. Moreover, during the gradual downward movement of the floating pressure plate 304, the pressure it exerts on the calibration protrusion 309 increases. The calibration protrusion 309 undergoes overall deformation and expands outward or into the receiving hole 308, while the protrusion part pressed between the floating pressure plate 304 and the coil 002 becomes flat. The flat protrusion part forms a rubber pad. The advantages of this are as follows: 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 overpressing 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 indentation or damage to the surface of the wire on the top surface of the coil 002.

[0039] Refer to Figure 3 and Figure 15 As shown in the figure, a material rack 101 is also provided on the machine table 004. Two groups of guide posts are fixedly connected to the top end of the material rack 101, which are respectively located at the four corner positions. Each group of guide posts has two guide posts. At least one material sheet 001 can be placed between the two guide posts. A guide opening is reserved on the material sheet 001 for inserting it onto the two guide posts. The material sheet 001 can be inserted between the two guide posts in sequence by manual or external equipment, so as to realize the stacking and temporary storage of multiple material sheets 001 on the material rack 101. Subsequently, as shown in Figure 1 and Figure 3 the operator can first open the door on the chassis 003, and then send the material rack 101 from outside the chassis 003 to the designated position on the machine table 004 through the conveyor belt 100. Subsequently, the material sheet 001 on the material rack 101 can be gradually grabbed onto the transfer table 200 by an external handling module, and this grasping operation is repeated until all the material sheets 001 on the material rack 101 are taken out. Finally, the empty material rack 101 can be pushed by the side push electric push rod on the machine table 004 onto another return conveyor belt 100 to send the empty material rack 101 outside the chassis 003, and in this way, automated continuous loading and unloading operations are realized reciprocally.

[0040] Refer to Figure 15 and Figure 3 As shown in the figure, a liftable support plate 103 is installed on the machine table 004. A through hole 102 for the support plate 103 to pass through is provided at the bottom end of the material rack 101. After the material rack 101 reaches the designated position on the machine table 004, the support plate 103 is driven by components such as an electric push rod installed at the bottom end of the machine table 004, so that the support plate 103 can move upward through the through hole 102 to lift the material sheet 001 to a predetermined height. It can be understood that after each material sheet 001 is grabbed from the material rack 101, the support plate 103 will move upward once, and the upward movement height each time is the overall thickness formed by one material sheet 001 + the coil 002, so as to ensure that the material sheet 001 at the top layer of the material rack 101 is at the grasping position / height of the external handling module, improving the processing efficiency. After the blank 001 is grabbed on the rack 101, the pallet 103 is controlled by the output end of an external electric push rod to move downward and move out of the tube through hole of the rack 101. The rack 101 is pushed laterally by an external drive and moved onto another return conveyor belt 100, and so on to achieve automated continuous loading and unloading operations.

[0041] Referring to Figure 5 , Figure 7 and Figure 8 As shown, the external drive components for controlling the flip plate 300 in this application are the lateral translation module one 400, the lifting module one 401, and the flipping module 402. Specifically, the lateral translation module one 400 is installed on the machine table 004, and the lifting module one 401 is installed on the lateral translation module one 400. The above two modules are composed of components similar to slide rails, lead screws, sliders, motors, etc. in the prior art. The lifting module one 401 is installed on the slider of the lateral translation module one 400 to form a reciprocating adjustment movement in the horizontal direction. The flipping module 402 is installed on the slider of the lifting module one 401. The flipping module 402 is composed of components similar to a substrate, a rotating motor, etc. in the prior art. The substrate is installed on the slider of the lifting module one 401 to form a reciprocating adjustment movement in the vertical direction. The rotating motor is installed on the substrate. The flip plate 300 is connected to the output shaft of the rotating motor on the rotating part of the flipping module 402 to achieve horizontal / vertical flipping adjustment of the flip plate 300. The above drive components are well-known prior art and will not be elaborated here. Generally speaking, the cooperation of the above three modules is used to position the flip plate 300 above the transfer table 200, grab the blank 001 and separate it from the transfer table 200 through lateral translation and lifting actions, and then make the blank 001 face and cooperate with the dispensing head 302 through a flipping action to complete the dispensing of the coil 002 on the blank 001. Moreover, after the dispensing of the coil 002 on one blank 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 non-dispensed blanks 001 / coils 002 can be moved to the dispensing head 302 to complete the dispensing of the coil 002 on the remaining blanks 001 until the dispensing of the coils 002 on the multiple (four) blanks 001 grabbed on the flip plate 300 is completed. Finally, the multiple blanks 001 on the flip plate 300 are transferred to the curing equipment through the control of each module.

[0042] Referring to Figure 6 and Figure 9As shown in the figure, the external driving components for controlling multiple dispensing heads 302 in this application are the second horizontal translation module 404 and the second lifting module 403. Specifically, the second lifting module 403 is also installed on the machine table 004, and the second horizontal translation module 404 is installed on the second lifting module 403. The above two modules are composed of components similar to slide rails, lead screws, sliders, motors, etc. in the prior art. The second horizontal translation module 404 is installed on the slider of the second lifting module 403 to form a reciprocating adjustment movement in the vertical direction. Multiple dispensing heads 302 are connected to the slider of the second lifting module 403 through a mounting plate, thereby forming a reciprocating adjustment movement in the horizontal direction of the dispensing heads 302. The above driving components are well-known prior art and will not be elaborated here. Generally speaking, the cooperation of the above two modules is used to move multiple dispensing heads 302 towards the coil 002 on the turning plate 300 for dispensing and move away from the turning plate 300 after dispensing.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
