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.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The present invention provides a microphone automatic wire welding device through improvement. The technical solution of the present invention is: like Figures 1 to 13 As shown, an embodiment of the present invention provides a microphone head automatic wire welding device, including a workbench 1 and a feeding assembly 6, the feeding assembly 6 includes two feeding mechanisms, the table top of the workbench 1 is provided with a rectangular opening 3, and the two feeding mechanisms are respectively arranged on both sides of the rectangular opening 3; A tilted material guide cover 2 is fixed to the bottom of the workbench 1. The cover opening of the material guide cover 2 is located below the rectangular opening 3. After the wire welding is completed, the microphone head falls into the material guide cover 2 and slides out of the workbench 1, which is convenient for workers to collect in a centralized manner. The feeding mechanism includes a support plate 601 and a plurality of clamps for clamping microphones. The support plate 601 is fixed to the workbench 1. A driving component for making the clamps move in a circular manner is provided on one side of the support plate 601. The table top of the workbench 1 is provided with a vibration plate 5, which is supplemented. A CCD camera and a blowing head are installed on a vibration groove on one side of the vibration plate 5. When the microphone is facing away from the vibration plate 5, the CCD camera collects the information and blows it back to the bottom of the plate through the blowing head to re-feed the material. At this time, the recognition method is more common in production and will not be described in detail here. The microphone is placed in the vibration plate 5, and the vibration plate 5 guides the microphone into the material guide strip by vibration. One side of the material guide strip of the vibration plate 5 is provided with a material moving component 9 that can rotate the microphone and move the microphone to the fixture. A visual acquisition module 4 for collecting microphone images is provided above the material guide strip of the vibration plate 5; The workbench 1 is provided with two integrated wire cutting and stripping machines 7, which are prior art. Figure 1 It is just one of the existing technologies, and other wire cutting and stripping machines 7 can be selected for replacement. The model of the wire cutting and stripping machine 7 is not limited here. Since the wire cutting and stripping machine 7 is an existing technology, its specific structure and working principle are not elaborated in detail. This wire cutting and stripping 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 machines 7 are respectively arranged adjacent to the two feeding mechanisms. The wire feeding ends of the two wire cutting and stripping machines 7 are aligned with a clamp at a certain place of the feeding mechanism. 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 clamped by the clamp; Among them, a soldering machine 8 for soldering wires is arranged above the clamp aligned with the wire feeding end of the wire cutting and stripping machine 7.

[0020] Specifically, in combination with Figure 7As shown, the driving assembly includes an annular guide rail 606 fixed on one side of the support plate 601, and the track sliding sleeve of the annular guide rail 606 is provided with a slider 607 adapted thereto, and each fixture is arranged one-to-one with each slider 607. The outer side of the support plate 601 is provided with a first driving mechanism that enables the slider 607 to move along the annular guide rail 606. The annular guide rail 606 and the slider 607 are both prior arts, so their specific structures and working principles are not described in detail. The first driving mechanism includes a servo motor 602, two rotating shafts 603, two synchronous wheels 604 and a synchronous belt 605. Both ends of the support plate 601 are provided with rotating shafts. 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 wheels 604 are coaxially fixed to the two rotating shafts 603, and the synchronous belt 605 is sleeved on the two synchronous wheels 604. Each slider 607 is fixed on the synchronous belt 605, and the multiple sliders 607 are equidistantly distributed on the synchronous belt 605. The servo motor 602 rotates the synchronous wheel 604 fixed thereto, and the two synchronous wheels 604 cause the slider 607 to slide along the annular guide rail 606 through the synchronous belt 605.

[0021] Specifically, in combination with Figure 8 -Attached Fig.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 in the middle of the placement block 617. A notch 619 is provided on one side of the hole slot 618. Slots connected to the hole slot 618 are provided on both sides of the placement block 617. Clamps 620 are slidably inserted in the two slots. Semicircular holes 621 are provided on the opposite sides of the two clamps 620. The rounded edges of the semicircular holes 621 are all arc angles. The arc angle is set to facilitate the insertion of the microphone. That is, when the microphone is inserted downward, it will be inserted between the two clamps 620 with the help of the arc angle. The concave plate 612 Both ends of the support plate 601 are rotatably mounted with connecting rods 622, and one end of the two connecting rods 622 is rotatably mounted on the two clamping blocks 620 respectively. A second driving mechanism is arranged on the outer side of the support plate 601 to enable the concave plate 612 to move linearly. 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. Each guide rod 616 is arranged so that the concave plate 612 can only move linearly relative to the placement table. It can be seen from the above connection relationship that when the concave plate 612 is away from the placement block 617, the concave plate 612 pulls the clamping block 620 out of the slot through the connecting rod 622.

[0022] Specifically, in combination with Fig. 9 -Attached Fig.11As shown, the second driving mechanism includes a reference block 610 and a guide ring rail 608, a slide bar 614 is fixed to the outside of the reference block 610, and a concave plate 612 is slidably sleeved on the slide bar 614, one end of the slide bar 614 is fixed to a limit plate 613, and a spring 615 is sleeved on the outside of the slide bar 614, and 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. Fig.10 and attached Fig.11 As shown, the microphone is inserted between the two clamping blocks 620. During this process, the microphone is inserted downwardly and inserted between the two clamping blocks 620 with the help of the arc angle. The microphone pushes the two clamping blocks 620, and the two clamping blocks 620 are pushed outward. The clamping blocks 620 push the concave plate 612 outward 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 applies a thrust to the concave plate 612, and the concave plate 612 applies a thrust to the clamping block 620 through the connecting rod 622, so that the clamping block 620 clamps the microphone. A contact rod 611 is rotatably installed on the outer side of the reference block 610, and a plurality of brackets are fixed between the guide ring rail 608 and the support plate 601. The two ends of the guide ring rail 608 are coaxially arranged with the two ends of the annular guide rail 606, and the rail surface of the guide ring rail 608 is provided with a guide groove 609. Below the guide groove 609 The servo motor 602 rotates the synchronous wheel 604 fixed thereto, and the two synchronous wheels 604 make the slider 607 slide along the annular guide rail 606 through the synchronous belt 605. When the slider 607 moves to the bottom of the synchronous belt 605, the contact rod 611 enters the lower part of the guide groove 609. Since the lower part of the guide 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 with the help of the limit plate 613 on the slide bar 614. At this time, the concave plate 612 is away from the placement block 617, and the concave plate 612 pulls the clamping block 620 out of the slot through the connecting rod 622, that is, the two clamping blocks 620 are separated from each other. The result is as shown in FIG. Fig. 9 shown.

[0023] Specifically, in combination with Figure 4As shown, the material moving assembly 9 includes a translation module 901, a vertical movement module 902, a rotation module 903 and a suction hand 904. A first fixed frame is fixed between the translation module 901 and the workbench 1, and the vertical movement module 902 is fixed on the moving end of the translation module 901, and the rotation module 903 is fixed on the moving end of the vertical movement module 902. The rotating end of the rotation module 903 is fixed to the suction hand 904. The translation module 901 in the material moving assembly 9 moves the vertical movement module 902 to above the material guide strip of the vibration disk 5, and the vertical movement module 902 makes the suction hand 904 on the rotation module 903 contact with the microphone, and the suction hand 904 absorbs the microphone, and then the vertical movement module 902 resets the suction hand 904 on the rotation module 903, and at this time the rotation module 903 makes the suction hand 904.

[0024] Specifically, in combination with Figure 1 , Figure 2 as well as Figure 3 As shown, the visual acquisition module 4 includes an acquisition camera, where the acquisition camera can be a common CCD camera, and the type of the acquisition camera is not limited here. A second fixed frame is fixed between the acquisition camera and the workbench 1, and the lens of the acquisition camera is aligned with one end of the guide strip of the vibration plate 5.

[0025] Specifically, in combination with Figure 5 As shown, the soldering machine 8 includes a moving module 804, a welding gun 801 and two tin spouting guns 802. A third fixed frame is fixed between the moving module 804 and the workbench 1. The moving end of the moving module 804 is fixed to the welding gun 801. The two tin spouting guns 802 are arranged in parallel and are located on one side of the welding gun 801. The tin spouting end of the tin spouting gun 802 is arranged obliquely and aligned with the welding gun 801. The moving end of the moving module 804 is fixed to the tin spouting gun 802. The welding head of the welding gun 801 is a flat welding head 803. 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 clamped by the clamp. At this time, the two tin spouting guns 802 in the soldering machine 8 work synchronously to spout tin bars. Then the moving end of the moving module 804 moves the welding gun 801 downward to perform wire welding. After the wire welding is completed, it is reset.

[0026] To supplement the above, a single-chip microcomputer is disposed inside the workbench 1, and the above-mentioned electrical components are electrically connected to the single-chip microcomputer.

[0027] Working principle: The microphone is placed in the vibration plate 5, and the vibration plate 5 guides the microphone into the guide bar through vibration. At this time, the acquisition camera in the visual acquisition module 4 acquires the image of the microphone, such as Fig.13 To collect the microphone image, Fig.12 Compare with the standard image of microphone head. Fig.12 The microphone head faces the left side with the smallest rotation angle; The translation module 901 in the material moving assembly 9 moves the vertical movement module 902 to the top of the material guide strip of the vibration plate 5. The vertical movement module 902 makes the suction hand 904 on the rotating module 903 contact with the microphone, and the suction hand 904 sucks the microphone. Then the vertical movement module 902 resets the suction hand 904 on the rotating module 903. At this time, the rotating module 903 makes the suction hand 904 rotate counterclockwise (the rotation angle is controlled by the single chip microcomputer) and rotates linearly to the same angle as the rotating module 903. Fig.12 The microphone heads of the microphones are aligned to the left, and then the translation module 901 moves the vertical translation module 902 to Figure 6 Above the left loading mechanism, the vertical moving module 902 moves the suction hand 904 on the rotating module 903 downward, and the suction hand 904 inserts the microphone between the two clamping blocks 620. During this process, the microphone is inserted downward, and is inserted between the two clamping blocks 620 with the help of the arc angle. The microphone pushes the two clamping blocks 620, and the two clamping blocks 620 are pushed outward. The clamping blocks 620 push the concave plate 612 outward 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 applies a thrust to the concave plate 612, and the concave plate 612 applies a thrust to the clamping block 620 through the connecting rod 622, so that the clamping block 620 clamps the microphone; After being fully clamped, the servo motor 602 rotates the synchronous wheel 604 fixed thereto, and the two synchronous wheels 604 make the slider 607 slide along the annular guide rail 606 through the synchronous belt 605, and the slider 607 moves to the wire cutting and stripping machine 7. At this time, the clamp on the slider 607 is aligned with the wire feeding end of the wire cutting and stripping machine 7, and 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; At this time, the two tin-dispensing guns 802 in the soldering machine 8 work synchronously to dispense tin bars, and then the moving end of the moving module 804 moves the soldering gun 801 downward to solder the wires. After the soldering is completed, it is reset. Then, the synchronous belt 605 moves the microphone with the completed wire welding downward, that is, the slider 607 moves to the bottom of the synchronous belt 605. At this time, the contact rod 611 enters the lower part of the guide groove 609. Since the lower part of the guide 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 with the help of the limit plate 613 on the slide bar 614. At this time, the concave plate 612 is away from the placement block 617. The concave plate 612 pulls the clamping block 620 out of the slot through the connecting rod 622, that is, the two clamping blocks 620 are separated from each other. The microphone with the completed wire welding falls into the material guide cover 2, thereby sliding out of the workbench 1, which is convenient for workers to collect in a centralized manner.
