Description

Technical Field

[0001] The present invention relates to the technical field of wire bonding equipment, and in particular to a microphone automatic wire bonding equipment. Background Art

[0002] The microphone is an energy conversion device that converts sound signals into electrical signals. It is a device that is exactly the opposite of a speaker. The microphone is soldered to a circuit board through wires to achieve electrical connection with the circuit board. Before soldering the microphone, two wires need to be soldered to the two electrodes of the microphone.

[0003] After searching, the patent document with the authorization announcement number CN106670816B discloses a microphone head automatic wire welding equipment, including a microphone head feeding mechanism, a material handling mechanism, a turntable mechanism, a guiding mechanism, a stripping and cutting mechanism, a tinning mechanism, a wire handling mechanism, a wire welding mechanism and a discharge mechanism. The invention automatically processes the wire into a conductor that can be used for welding. The wire handling mechanism can carry the wire to the fixture of the turntable, so that the wire is arranged and the alignment with the microphone head is completed. The wire welding mechanism automatically aligns for welding. Finally, the discharge mechanism removes the microphone head of the welding wire from the fixture, the turntable continues to rotate, and the vacant fixture continues to rotate to the vicinity of the microphone head feeding mechanism, and the operations of loading, tinning, swinging, welding, and unloading are realized again. It can be seen that the wire welding equipment of the invention realizes the fully automatic wire welding of the microphone head. The entire process of loading, tinning, handling, swinging, welding and unloading does not require manual operation, which improves production efficiency and the stability of product welding quality.

[0004] Based on the above search and the prior art, it is found that: currently, a COD camera module is generally used to collect microphone images, and then a clamping module is used to clamp the microphone, and the clamping module is rotated by a rotating module, and then the microphone is straightened. The microphone must be at most 180 degrees forward or reverse.

[0039] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] The present invention provides an automatic wire soldering device for microphone heads by improvement. The technical solution of the present invention is as follows:

[0041] As Figures 1 to 13 shown, the embodiment of the present invention provides an automatic wire soldering device for microphone heads, including a workbench 1 and a loading assembly 6. The loading assembly 6 includes two loading mechanisms. A rectangular opening 3 is formed on the tabletop of the workbench 1, and the two loading mechanisms are respectively arranged on both sides of the rectangular opening 3;

[0042] A slantingly arranged feeding hood 2 is fixed to the bottom of the tabletop of the workbench 1. The hood opening of the feeding hood 2 is located below the rectangular opening 3. The microphone heads after wire soldering fall into the feeding hood 2 and then slide out of the workbench 1, facilitating centralized collection by workers;

[0043] The loading mechanism includes a support plate 601 and a plurality of clamps for clamping the microphone heads. The support plate 601 is fixed to the workbench 1, and a driving assembly for circularly moving the clamps is arranged on one side of the support plate 601;

[0044] The tabletop of the workbench 1 is provided with a vibrating bowl 5 for replenishment. On one side of the vibrating bowl 5, a CCD camera and a blowing head are installed in the vibrating groove. When the microphone head is facing away from the vibrating bowl 5, it is collected by the CCD camera and blown back to the bottom of the bowl through the blowing head for re-feeding. This recognition method is relatively common in production and will not be described in detail here. The microphone head is placed in the vibrating bowl 5, and the vibrating bowl 5 guides the microphone head into the guide bar in a vibrating manner. On one side of the guide bar of the vibrating bowl 5, there is a material transfer component 9 that can rotate the microphone head and move the microphone head to the fixture.

[0045] Above the guide bar of the vibrating bowl 5, a vision acquisition module 4 for acquiring images of the microphone head is provided.

[0046] Two wire cutting and stripping integrated machines 7 are fixed on the tabletop of the workbench 1. The wire cutting and stripping integrated machine 7 is an existing technology. Figure 1 It is only to show one kind in the existing technology, and other wire cutting and stripping integrated machines 7 can be selected for replacement. The model of the wire cutting and stripping integrated machine 7 is not limited here. Since the wire cutting and stripping integrated machine 7 is an existing technology, its specific structure and working principle will not be described in detail. This wire cutting and stripping integrated machine 7 is a double wire feeding type, that is, it can feed two wires at a time, and the two wire cutting and stripping integrated machines 7 are respectively arranged adjacent to two feeding mechanisms. The wire feeding ends of the two wire cutting and stripping integrated machines 7 are exactly aligned with a certain fixture of the feeding mechanism. The wire cutting and stripping integrated machine 7 feeds the wire so that the stripped end of the wire contacts the solder point of the microphone head clamped by the fixture.

[0047] Among them, above the fixture aligned with the wire feeding end of the wire cutting and stripping integrated machine 7, a soldering machine 8 for wire soldering is provided.

[0048] Specifically, in combination with the attached Figure 7As shown, the driving assembly includes an annular guide rail 606 fixed on one side of the support plate 601. A slider 607 adapted to it is slidably sleeved on the track of the annular guide rail 606. Each fixture is arranged one-to-one with each slider 607. A first driving mechanism for moving the slider 607 along the annular guide rail 606 is arranged outside the support plate 601. The annular guide rail 606 and the slider 607 are both prior arts, so their specific structures and working principles will not be elaborated in detail. The first driving mechanism includes a servo motor 602, two rotating shafts 603, two synchronous pulleys 604 and a synchronous belt 605. Rotating holes are provided at both ends of the support plate 601, and the two rotating shafts 603 are respectively rotatably installed in the two rotating holes. The servo motor 602 is fixed to the support plate 601, and the output shaft of the servo motor 602 is coaxially fixed to one of the rotating shafts 603. The two synchronous pulleys 604 are respectively coaxially fixed to the two rotating shafts 603, and the synchronous belt 605 is sleeved on the two synchronous pulleys 604. Each slider 607 is fixed on the synchronous belt 605, and multiple sliders 607 are equidistantly distributed on the synchronous belt 605; the servo motor 602 rotates the synchronous pulley 604 fixed to it, and the two synchronous pulleys 604 make the slider 607 slide along the annular guide rail 606 through the synchronous belt 605.

[0049] Specifically, in combination with the attached Figure 8 - attached Figure 11 As shown, the fixture includes a placement block 617 and a concave plate 612. The placement block 617 is fixed to the slider 607. A hole slot 618 is provided at the middle position of the placement block 617. A notch 619 is provided on one side of the hole slot 618. Slots communicating with the hole slot 618 are provided on both sides of the placement block 617, and clamping blocks 620 are slidably inserted into the slots of the two slots. Semi-circular holes 621 are provided on the opposite sides of the two clamping blocks 620. The circular edges of the semi-circular holes 621 are all arc angles. The setting of the arc angles is to facilitate the insertion of the microphone head. That is, during the process of the microphone head being inserted downward, it will be inserted between the two clamping blocks 620 by means of the arc angles. Connecting rods 622 are rotatably installed at both ends of the concave plate 612, and one ends of the two connecting rods 622 are respectively rotatably installed on the two clamping blocks 620. A second driving mechanism for enabling the concave plate 612 to perform linear movement is arranged outside the support plate 601. A plurality of guide rods 616 are fixed to one side of the placement block 617, and the concave plate 612 is slidably sleeved on each guide rod 616. The setting of each guide rod 616 is to ensure that the concave plate 612 can only perform relative linear movement relative to the placement table; through the above connection relationship, it can be seen that when the concave plate 612 moves away from the placement block 617, the concave plate 612 pulls the clamping blocks 620 out of the slots through the connecting rods 622.

[0050] Specifically, in combination with the attached Figure 9 - attached Figure 11As shown, the second driving mechanism includes a reference block 610 and a guiding ring rail 608. A sliding rod 614 is fixed to the outer side of the reference block 610, and a concave plate 612 is slidably sleeved on the sliding rod 614. A limiting plate 613 is fixed to one end of the sliding rod 614. A spring 615 is sleeved on the outer side of the sliding rod 614. The two ends of the spring 615 are respectively in contact with the concave plate 612 and the reference block 610 and the spring 615 is in a compressed state. Combining with the attached Figure 10 and the attached Figure 11 As shown, insert the microphone head between the two clamping blocks 620. During this process, when the microphone head is inserted downward, it will be inserted between the two clamping blocks 620 by means of the arc angle. The microphone head pushes the two clamping blocks 620, and the two clamping blocks 620 are pushed outwards. The clamping blocks 620 push the concave plate 612 outwards through the connecting rod 622. At this time, the concave plate 612 moves along the sliding rod 614, and the spring 615 is compressed. The spring 615 exerts a thrust on the concave plate 612, and the concave plate 612 exerts a thrust on the clamping blocks 620 through the connecting rod 622, so that the clamping blocks 620 clamp the microphone head. A contact rod 611 is rotatably installed on the outer side of the reference block 610. A plurality of brackets are jointly fixed between the guiding ring rail 608 and the support plate 601. The two ends of the guiding ring rail 608 are coaxially arranged with the two ends of the annular guide rail 606 respectively. A guiding groove 609 is formed on the rail surface of the guiding ring rail 608. The lower part of the guiding groove 609 is far away from the support plate 601, and the upper part of the guiding groove 609 is close to the support plate 601. One end of the contact rod 611 is arranged in the guiding groove 609. The servo motor 602 rotates the synchronous pulley 604 fixed to it. The two synchronous pulleys 604 make the slider 607 slide along the annular guide rail 606 through the synchronous belt 605. When the slider 607 moves below the synchronous belt 605, the contact rod 611 enters the lower part of the guiding groove 609. Since the lower part of the guiding groove 609 is far away from the support plate 601, the contact rod 611 pulls the reference block 610 away from the support plate 601. At this time, the reference block 610 pulls the concave plate 612 by means of the limiting plate 613 on the sliding rod 614. At this time, the concave plate 612 is away from the placing block 617. The concave plate 612 pulls the clamping blocks 620 out of the slots through the connecting rod 622, that is, the two clamping blocks 620 are separated from each other. The result is as Figure 9 shown.

[0051] Specifically, combining with the attached Figure 4As shown, the material transfer component 9 includes a horizontal translation module 901, a vertical translation module 902, a rotation module 903, and a suction gripper 904. A first fixing bracket is fixedly connected between the horizontal translation module 901 and the workbench 1, and the vertical translation module 902 is fixed on the moving end of the horizontal translation module 901. The rotation module 903 is fixed on the moving end of the vertical translation module 902, and the rotating end of the rotation module 903 is fixedly connected to the suction gripper 904. The horizontal translation module 901 in the material transfer component 9 moves the vertical translation module 902 above the guiding strip of the vibrating bowl 5. The vertical translation module 902 makes the suction gripper 904 on the rotation module 903 contact the microphone head, and the suction gripper 904 sucks the microphone head. Subsequently, the vertical translation module 902 resets the suction gripper 904 on the rotation module 903. At this time, the rotation module 903 makes the suction gripper 904...

[0052] Specifically, in combination with the attached... Figure 1 、 Figure 2 and Figure 3 As shown, the visual acquisition module 4 includes an acquisition camera. Here, a common CCD camera can be selected for the acquisition camera, and the type of the acquisition camera is not limited herein. A second fixing bracket is fixedly connected between the acquisition camera and the workbench 1, and the lens of the acquisition camera is aligned with one end of the guiding strip of the vibrating bowl 5.

[0053] Specifically, in combination with the attached... Figure 5 As shown, the soldering machine 8 includes a moving module 804, a soldering gun 801, and two tin spraying guns 802. A third fixing bracket is fixedly connected between the moving module 804 and the workbench 1. The moving end of the moving module 804 is fixedly connected to the soldering gun 801. The two tin spraying guns 802 are arranged in parallel and are located on one side of the soldering gun 801. The tin spraying end of the tin spraying gun 802 is inclined and aligned with the soldering gun 801. The moving end of the moving module 804 is fixedly connected to the tin spraying gun 802. The soldering head of the soldering gun 801 is a flat soldering head 803. The wire cutting and stripping integrated machine 7 feeds the wire, so that the stripped end of the wire contacts the tin point of the microphone head clamped by the fixture. At this time, the two tin spraying guns 802 in the soldering machine 8 work synchronously to spray out the tin strip. Subsequently, the moving end of the moving module 804 makes the soldering gun 801 move down to perform wire soldering. After the wire soldering is completed, it is then reset.

[0054] For supplementary description of the above, a single-chip microcomputer is arranged inside the workbench 1, and the above-mentioned various electrical components are electrically connected to the single-chip microcomputer.

[0055] Working principle: Place the microphone head in the vibrating bowl 5. The vibrating bowl 5 guides the microphone head into the guiding strip in a vibrating manner. At this time, the acquisition camera in the visual acquisition module 4 acquires the image of the microphone head. For example... Figure 13 is to acquire the image of the microphone head, and compare it with... Figure 12 the standard image of the microphone head... Figure 12 The microphone head with the smallest rotation angle to the left...

[0056] The translation module 901 within the material transfer assembly 9 moves the vertical translation module 902 above the guiding bar of the vibrating bowl 5. The vertical translation module 902 brings the suction gripper 904 on the rotation module 903 into contact with the microphone head. The suction gripper 904 sucks the microphone head. Subsequently, the vertical translation module 902 resets the suction gripper 904 on the rotation module 903. At this time, the rotation module 903 rotates the suction gripper 904 counterclockwise (the rotation angle is controlled by the single-chip microcomputer), and linearly rotates until it is aligned with the Figure 12 microphone head facing the left side. Subsequently, the translation module 901 moves the vertical translation module 902 above the feeding mechanism on the left side. The vertical translation module 902 lowers the suction gripper 904 on the rotation module 903, and the suction gripper 904 inserts the microphone head between two clamping blocks 620. During this process, when the microphone head is inserted downward, it will be inserted between the two clamping blocks 620 by means of the arc angle. The microphone head pushes the two clamping blocks 620, and the two clamping blocks 620 are pushed outwards. The clamping blocks 620 push the concave plate 612 outwards through the connecting rod 622. At this time, the concave plate 612 moves along the sliding rod 614, and the spring 615 is compressed. The spring 615 exerts a thrust on the concave plate 612, and the concave plate 612 exerts a thrust on the clamping blocks 620 through the connecting rod 622, so that the clamping blocks 620 clamp the microphone head; Figure 6 After being completely clamped, the servo motor 602 rotates the synchronous pulley 604 fixed to it. The two synchronous pulleys 604 make the slider 607 slide along the annular guide rail 606 through the synchronous belt 605. The slider 607 moves to the wire cutting and stripping machine 7. At this time, the fixture on the slider 607 is aligned with the wire feeding end of the wire cutting and stripping machine 7. The wire cutting and stripping machine 7 feeds the wire, so that the stripped end of the wire contacts the tin point of the microphone head;

[0057] At this time, the two tin spraying guns 802 in the soldering machine 8 work synchronously, spraying tin bars. Subsequently, the moving end of the moving module 804 lowers the soldering gun 801 for wire soldering. After the wire soldering is completed, it is then reset;

[0058] Subsequently, the synchronous belt 605 moves the soldered microphone head below, that is, the slider 607 moves below the synchronous belt 605. At this time, the contact rod 611 enters the lower part of the guiding groove 609. Since the lower part of the guiding groove 609 is far from the support plate 601, the contact rod 611 pulls the reference block 610 away from the support plate 601. At this time, the reference block 610 pulls the concave plate 612 by means of the limit plate 613 on the sliding rod 614. At this time, the concave plate 612 moves away from the placing block 617. The concave plate 612 pulls the clamping blocks 620 out of the slots through the connecting rod 622, that is, the two clamping blocks 620 separate from each other. The soldered microphone head falls into the guiding cover 2, and thus slides out of the workbench 1 for the worker to collect centrally.

[0059] Subsequently, the synchronous belt 605 moves the soldered microphone head below, that is, the slider 607 moves below the synchronous belt 605. At this time, the contact rod 611 enters the lower part of the guiding groove 609. Since the lower part of the guiding groove 609 is far from the support plate 601, the contact rod 611 pulls the reference block 610 away from the support plate 601. At this time, the reference block 610 pulls the concave plate 612 by means of the limit plate 613 on the sliding rod 614. At this time, the concave plate 612 moves away from the placing block 617. The concave plate 612 pulls the clamping blocks 620 out of the slots through the connecting rod 622, that is, the two clamping blocks 620 separate from each other. The soldered microphone head falls into the guiding cover 2, and thus slides out of the workbench 1 for the worker to collect centrally.

[0060] The foregoing description enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
