Description

Technical Field

[0001] This utility model relates to the field of pin welding technology, specifically a microphone pin welding fixture. Background Technology

[0002] Lead soldering is a process of connecting the leads of electronic components to pads on a circuit board. Solder is typically used to connect the leads and pads to ensure electrical contact and mechanical stability of the circuit. This process is an important step in electronic assembly and is widely used to connect various electronic components, such as integrated circuits, sensors, and connectors. Soldering fixtures are tools specifically designed for the soldering process to position and fix components and help to execute the soldering process efficiently and accurately. When soldering leads to a microphone's circuit board, a soldering fixture is needed to limit the position of the microphone.

[0003] A search revealed a utility model patent in China with patent publication number CN222999829U, which discloses a microphone pin welding fixture. The fixture is described as including a base, with a support frame and a buffer pad fixedly mounted on the top of the base. Movable blocks are provided on the inner side of the base. During use, the fixture's stability is improved by incorporating limiting blocks and reinforcing blocks, preventing the multiple sets of movable blocks from moving along different paths and improving the fixture's efficiency. However, the above device still has some shortcomings. For example, when clamping and fixing the microphone, it does not actually fix the microphone securely. The microphone clamped in the center of the groove on the base will be close to the side of the buffer pad. The two placement cylinders can only be adjusted to move away from or closer to each other, which is not convenient for arbitrary adjustment. Therefore, after clamping microphones of different specifications, the above device is not convenient for aligning the pins placed in the placement cylinders with the circuit board on the microphone for quick soldering. Its applicability is insufficient. Moreover, when placing microphones, manual labor is required to clamp multiple microphones, which is inconvenient. The process of removing microphones is also inconvenient and may bend the pins, which will affect the production quality of the microphones to a certain extent. Therefore, we propose a microphone pin soldering fixture. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a microphone pin welding fixture to solve the problems mentioned in the background art. In the prior art, after clamping microphones of different specifications, the aforementioned device does not easily align the pins placed inside the placement cylinder with the circuit board on the microphone for rapid welding, thus its applicability is insufficient. Furthermore, when placing microphones, manual labor is required to clamp multiple microphones, making the operation inconvenient. Removing the microphones is also inconvenient and may bend the pins, which to some extent affects the production quality of the microphones.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a microphone pin welding fixture, including a pin adjustment mechanism, and further comprising:

[0008] Base;

[0009] A clamping and fixing mechanism is mounted on a base. The mechanism includes a placement plate fixedly connected to the base. The placement plate has a groove and four placement openings. A motor is mounted on the placement plate. A control screw is rotatably connected within the groove. The output end of the motor passes through the groove and is fixedly connected to the control screw. The control screw consists of four bidirectional screws. Eight control openings are formed within the groove, arranged in pairs. Each pair of control openings communicates with a placement opening. Two moving blocks are threaded onto the bidirectional screws. A connecting plate is fixedly connected to each moving block. The connecting plate is located within the control openings. A clamping plate is fixedly connected to the connecting plate for clamping and fixing the microphone.

[0010] A lifting mechanism, which is mounted on the base, is used to drive the pin adjustment mechanism to rise and fall;

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] Please see Figures 1-4 A microphone pin soldering fixture, including a pin adjustment mechanism 1, and further comprising:

[0028] Base 2;

[0029] A clamping and fixing mechanism is mounted on a base 2. The clamping and fixing mechanism includes a placement plate 3, which is fixedly connected to the base 2. The placement plate 3 has a groove and four placement openings. A motor 4 is mounted on the placement plate 3. A control screw is rotatably connected in the groove. The output end of the motor 4 passes through the groove and is fixedly connected to the control screw. The control screw consists of four bidirectional screws 5. Eight control openings are opened in the groove. The eight control openings are arranged in pairs. Both control openings are connected to the placement openings. Two moving blocks 6 are threadedly connected to the bidirectional screws 5. A connecting plate 7 is fixedly connected to the moving blocks 6. The connecting plate 7 is located in the control openings. A clamping plate 8 is fixedly connected to the connecting plate 7. The motor 4 provides power. The rotation of the bidirectional screws 5 drives the moving blocks 6 to move. The moving blocks 6, connecting blocks 17, etc., drive the clamping plate 8 to move. The clamping plate 8 is used to clamp and fix the microphone.

[0030] The lifting mechanism is mounted on the base 2 and includes two power boxes 9, both fixedly connected to the base 2. A slider 10 is slidably connected inside each power box 9. An electric cylinder 11 is installed between the slider 10 and the power box 9. One end of the slider 10 passes through an opening in the power box 9 and is fixedly connected to a lifting block 12. A pin adjustment mechanism 1 is installed between the two lifting blocks 12. The electric cylinder 11, slider 10, etc., are used to lift the pin adjustment mechanism 1, facilitating the removal of the microphone with soldered pins. Further explanation is needed regarding the synchronization of the two electric cylinders 11. The electric cylinders 11 are typically driven by servo motors 4. Synchronization control methods include: PLC control: processing sensor signals and IO signals through a programmable logic controller to achieve multi-cylinder 11 collaboration; EtherCAT bus: supporting high-speed real-time communication, suitable for millisecond-level synchronous response scenarios; CAN communication: communicating with the controller through a servo driver. Protocol compatibility must be considered. Many synchronization methods are existing technologies, so they will not be detailed here.

[0031] The fume extraction mechanism is mounted on the base 2 and includes a mounting plate 13, which is fixedly connected to the base 2. A fume purifier 14 is mounted on the mounting plate 13, and the suction end of the fume purifier 14 is connected to a fixed pipe 15. Multiple suction buckets 16 are connected to the fixed pipe 15, and the suction buckets 16 are fixedly connected to the placement plate 3 through a connecting block 17. The fume purifier 14 is used to extract and purify the fume, while the fixed pipe 15, suction buckets 16, etc. are used for auxiliary purposes to facilitate suction from multiple positions for extracting and purifying the fume generated during welding.

[0032] A protective pad 18 is fixedly connected to the clamp 8 to protect the microphone. The protective pad 18 is malleable, which makes it easier to fix microphones of different specifications.

[0033] A maintenance plate 19 is installed in the groove, and a maintenance plate 20 is installed on the power box 9, for convenient maintenance, debugging, etc.

[0034] A protective net 21 is fixedly connected inside the suction hopper 16 to provide protection and prevent other items from being sucked in.

[0035] It should be further explained that the electric cylinder 11, the fume purifier 14, and the motor 4 in this embodiment are conventional devices known to those skilled in the art and available on the market. Models can be selected or customized according to actual needs. In this patent, we only use them without improving their structure and function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. They will not be described in detail here. The electric cylinder 11, the fume purifier 14, and the motor 4 are equipped with matching control switches. The installation position of the control switches can be selected according to actual usage needs to facilitate operation and control by the operator.

[0036] In summary, the working principle and process of this microphone pin welding fixture are as follows: First, place the fixture at the desired location and connect the motor 4 to the forward and reverse circuits according to the instruction manual. Then, during use, place multiple microphones into the designated slots, positioning them between the two clamping plates 8. Start the motor 4, which drives four bidirectional screws 5 to rotate. The screws 5 move the two moving blocks 6 closer together or further apart, which in turn move the connecting block 17 and the clamping plates 8. The two clamping plates 8 then hold and fix the microphones in place. The operator can then control the pin welding according to the microphone's specifications. The pin adjustment mechanism 1 allows for easy adjustment to a position compatible with the microphone. The pins are then inserted into the pin adjustment mechanism 1, and the operator solders them onto the circuit board on the microphone. During soldering, the fume purifier 14 is activated. The fume purifier 14, through the fixed pipe 15 and dust collection bucket, absorbs and purifies the fumes or harmful gases generated during soldering. After soldering, the electric cylinder 11 is activated. The electric cylinder 11 drives the slider 10, lifting plate, and pin adjustment mechanism 1 to rise and fall, facilitating the disengagement of the pins from the pin adjustment mechanism 1. This makes it easier to remove the microphone with the soldered pins, ensuring the soldering quality of the microphone and improving its practicality.

[0037] The pin adjustment mechanism 1 involved in this solution is a patented technology disclosed in Chinese Utility Model Patent Publication (Announcement) No. CN222999829U. Its internal structure and working principle are well known to those skilled in the art and are not the innovation of this patent. The innovation of this patent lies in the clamping, removal and dust removal of the microphone. Therefore, this patent will not elaborate on its internal structure and working principle.

[0038] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
