Description

Technical Field

[0001] The utility model relates to the technical field of earphone production and manufacturing, and more specifically, to an inductive starting module and a glue dispensing device. Background Art

[0002] In the earphone manufacturing process, glue dispensing equipment plays a vital role and is widely used in glue dispensing operations of various earphone components, including but not limited to the bonding of earplugs and shells and the fixing of speaker units. The working principle of the equipment is based on the combination of precision machinery and fluid control technology. It drives one or more inclined needles through a rotating shaft, so that the needles form a certain angle with the vertical direction, so as to accurately apply glue to the inner and outer walls of the object.

[0003] The current four-axis dispensing equipment has made innovations in mechanical structure. It adds a rotating axis based on the traditional X, Y, and Z three-axis manipulator. This design enables the equipment to achieve 360-degree all-round rotating dispensing. This four-axis linkage design not only improves the flexibility of operation, but also enables the equipment to meet the dispensing needs of five-sided special-shaped products, greatly broadening the scope of application.

[0004] During the operation of existing dispensing equipment, operators generally rely on manually clicking the start button to trigger the operation of the equipment. Although this operation method is intuitive, it has significant defects in practical applications. For equipment with a high dispensing frequency, operators need to frequently click the start button, which may involve thousands or even tens of thousands of repetitive actions every day. This high-frequency repetitive operation not only greatly increases the workload of operators, but also easily leads to the risk of operator fatigue and misoperation.

[0005] Specifically, for high-frequency dispensing equipment, if the start button needs to be operated 5,000 to 10,000 times a day, assuming that each operation takes 1 second, then the average daily start button operation alone will take 7,000 seconds, or about 1.94 hours. This long-term repetitive operation not only prolongs the operation time and reduces work efficiency, but also long-term hand movements can easily cause operator fatigue and may even cause hand injuries. What's more serious is that frequent click operations increase the possibility of misoperation. During long-term continuous work, operators may make operational errors due to fatigue or distraction, which in turn affects the accuracy and quality of dispensing. This may not only damage the performance of the product, but also have an adverse effect on the entire production line. Utility Model Content

[0008] Furthermore, the toggle switch is a SK12D07 toggle switch or a SS22D01 toggle switch.

[0010] Further, the groove extends along the height direction of the mounting seat to penetrate the lower surface of the mounting seat.

[0011] Furthermore, an interface is provided on one side of the workbench, and the interface and the EE-SPY401-1 photoelectric sensor are connected via a signal line.

[0020] The following detailed description and drawings of the embodiments of the present invention are used to illustrate the principle of the present invention, but cannot be used to limit the scope of the present invention, that is, the present invention is not limited to the embodiments described.

[0021] In order to better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0022] In the manufacturing process of headphones, dispensing equipment plays a vital role and is widely used in the dispensing of various parts of headphones. This is mainly due to its high precision, high efficiency and automation, which can ensure the accuracy and consistency of the dispensing process, thereby greatly improving the production quality and efficiency of headphones.

[0023] Glue dispensing equipment can accurately control the amount of glue dispensed, avoid too much or too little glue, and ensure that the glue dispensing of each component meets the standard. This is especially important for the production of headphones, because too much glue may result in poor product appearance and even require reprocessing and disassembly of the product; while too little glue may cause loose connection of components, affecting the normal use of the headphones. In addition, headphones are usually made of a variety of materials such as metal and plastic, including metal aluminum, stainless steel, ABS plastic, etc. These materials have different requirements for the viscosity and curing speed of glue, and glue dispensing equipment can use suitable glue and accelerators according to different material properties to ensure the quality and effect of glue dispensing. In the production of headphones, various components such as speakers, diaphragms, etc. need to be fixed with glue. Glue dispensing equipment can accurately control the position and amount of glue dispensing to ensure the firmness of the connection between each component, thereby meeting the production requirements of headphones.

[0024] However, in the actual production process of headphones, the inventors found that after the existing dispensing equipment is placed in the product, the operator usually needs to manually click the start button to start the equipment to start the operation. Although this operation method is direct and clear, it has obvious shortcomings. Since the start button needs to be clicked every time the work is done, for dispensing equipment with a high dispensing frequency, the operator needs to repeat the start button operation thousands or even tens of thousands of times a day. This not only increases the workload of the operator, but also easily leads to operational fatigue and misoperation. For example: For dispensing equipment with a high dispensing frequency, the start button must be operated 5,000 to 10,000 times every day. Calculated by time, each press of the start button is calculated as 1 second. Based on an average daily operation of 7,000 times, it takes a total of 7,000 seconds, or 1.92 hours. In the long run, it greatly increases the operation time and increases the fatigue of the operator.

[0025] Based on this, the utility model provides an induction start module, see Figure 1 As shown, the inductive starting module includes a DH48S time relay 1, an EE-SPY401-1 photoelectric sensor 2, a toggle switch 3 and a transformer 4. In this embodiment, the EE-SPY401-1 photoelectric sensor 2 detects the workpiece, and the EE-SPY401-1 photoelectric sensor 2 sends a signal to the DH48S time relay 1, thereby controlling the start button to short-circuit, simulating the pressing operation of the start button. This design enables the dispensing equipment to start automatically after detecting the workpiece without manual intervention, thereby greatly improving production efficiency. Compared with the traditional dispensing machine startup, which usually requires manual detection of the workpiece and manual pressing of the start button, when the inductive starting module provided by the utility model is added to the dispensing equipment, there is no need for manual frequent pressing of the start button to start the dispensing equipment, thereby improving production quality.

[0026] Specifically, the transformer 4 is used to access the 220V AC circuit, and the 220V AC voltage is converted into a 24V DC voltage through the transformer 4. The transformer 4, the toggle switch 3, the EE-SPY401-1 photoelectric sensor 2 and the DH48S time relay 1 and other components constitute a relatively stable circuit system, which not only ensures that the inductive starting module can operate stably in a continuous production environment and reduce failures and downtime, but also helps to reduce current fluctuations and electromagnetic interference in the circuit, thereby improving the circuit stability of the entire inductive starting module and ensuring the long-term stable operation of the inductive starting module.

[0027] In this embodiment, one end of the toggle switch 3 is connected to the transformer 4, the positive end of the EE-SPY401-1 photoelectric sensor 2 and the fourth hole of the DH48S time relay 1 are respectively connected to the other end of the toggle switch 3, the negative end of the EE-SPY401-1 photoelectric sensor 2 is connected to the transformer 4, the signal end of the EE-SPY401-1 photoelectric sensor 2 is connected to the second hole of the DH48S time relay 1, and the sixth hole of the DH48S time relay 1 and the eighth hole of the DH48S time relay 1 are respectively connected to the two ends of the start button. In this design, when the EE-SPY401-1 photoelectric sensor 2 detects the workpiece, the EE-SPY401-1 photoelectric sensor 2 sends a signal to the second hole of the DH48S time relay 1. After receiving the signal, the DH48S time relay 1 controls the on-off state of the sixth hole and the eighth hole. When the sixth hole and the eighth hole are closed, the pressing operation of the start button is simulated, thereby starting the dispensing equipment. That is, the EE-SPY401-1 photoelectric sensor 2 in the embodiment of the utility model sends a signal to the DH48S time relay 1, which controls the start button to be short-circuited through the DH48S time relay 1 to simulate the start button pressing operation, so that the dispensing equipment can automatically start after automatically detecting the workpiece. No manual detection is required, and no manual pressing of the start button is required to start the dispensing equipment. In addition, the circuit of the inductive starting module is relatively stable and can be used in continuous production. It is not only convenient and fast, but also does not require changes to the core module of the dispensing equipment and can be directly installed and used.

[0028] Preferably, the toggle switch 3 is a SK12D07 toggle switch or a SS22D01 toggle switch.

[0029] For further explanation, the embodiment of the utility model also provides a working principle of an inductive starting module, which is as follows:

[0030] The inductive start module uses DH48SDH48S time relay to control the start button short circuit to realize automatic start after the dispensing equipment detects the workpiece. First, after the 220V power supply is connected to the transformer 4, the 220V AC voltage is converted into a 24V DC voltage output through the transformer 4, and the positive pole of the transformer 4 is connected to the toggle switch 3. This design is to facilitate the control of the operation of the entire induction circuit later. After passing through the toggle switch 3, the 24V working voltage is connected to the positive pole of the EE-SPY401-1 EE-SPY401-1 photoelectric sensor, that is, the toggle switch 3 is connected to the brown end of the EE-SPY401-1 EE-SPY401-1 photoelectric sensor. At the same time, the toggle switch 3 is also connected to the fourth hole of the DH48SDH48S time relay. The current passes through the fourth hole of the DH48SDH48S time relay directly to the first hole of the DH48SDH48S time relay and then returns to the negative pole of the 220V power supply circuit. The 220V power supply is conducted to the negative pole of the EE-SPY401-1 EE-SPY401-1 photoelectric sensor through the transformer 4, that is, the transformer 4 is connected to the blue end of the EE-SPY401-1 EE-SPY401-1 photoelectric sensor. When the EE-SPY401-1 EE-SPY401-1 photoelectric sensor detects a workpiece, the positive and negative electrodes of the EE-SPY401-1 EE-SPY401-1 photoelectric sensor are connected to each other, so that the positive and negative electrodes of the EE-SPY401-1 EE-SPY401-1 photoelectric sensor are connected to the 24V working voltage, the EE-SPY401-1 EE-SPY401-1 photoelectric sensor is closed, and the signal end of the EE-SPY401-1 EE-SPY401-1 photoelectric sensor outputs a signal, that is, the black end of the EE-SPY401-1 EE-SPY401-1 photoelectric sensor is connected to the DH48. The negative pole of the SDH48S time relay, that is, the second hole of the DH48SDH48S time relay, at the same time, the sixth hole and the eighth hole of the DH48SDH48S time relay are respectively connected to the two ends of the start button of the dispensing equipment. When the EE-SPY401-1 EE-SPY401-1 photoelectric sensor is started, the signal end of the EE-SPY401-1 EE-SPY401-1 photoelectric sensor is energized to the DH48SDH48S time relay, and the DH48SDH48S time relay works. The sixth hole and the eighth hole of the DH48SDH48S time relay are closed, simulating the start button pressing operation, thereby completing the short circuit and starting the dispensing equipment.

[0031] In addition, the utility model also provides a dispensing device, see Figures 2-3As shown, the dispensing equipment includes the above-mentioned inductive starting module and a workbench 5, on which a Y-axis servo slide 6 and a dispensing plate 7 movably mounted on the Y-axis servo slide 6 are provided, and on the dispensing plate 7 a mounting seat 8 is provided, and on one side of the mounting seat 8 a groove for accommodating the EE-SPY401-1 type photoelectric sensor 2 is provided.

[0032] Specifically, the dispensing equipment introduces an inductive start module and uses the EE-SPY401-1 photoelectric sensor 2 to enable the dispensing equipment to accurately identify the position of the workpiece and start the dispensing operation. This automated working method greatly improves production efficiency and reduces manual intervention. Secondly, the Y-axis servo slide 6, as the support and driving mechanism of the dispensing plate 7, has the characteristics of high precision and high stability, which can ensure the stability and accuracy of the dispensing plate 7 during movement, thereby ensuring the stability and reliability of the dispensing operation. When the workpiece is placed on the mounting seat 8, the EE-SPY401-1 photoelectric sensor 2 senses the workpiece, and the EE-SPY401-1 photoelectric sensor 2 sends a signal to the second hole of the DH48S time relay 1. After receiving the signal, the DH48S time relay 1 controls the on and off status of the sixth hole and the eighth hole. When the sixth hole and the eighth hole are closed, the pressing operation of the start button is simulated, thereby starting the dispensing equipment.

[0033] Preferably, the groove extends along the height direction of the mounting seat 8 to penetrate the lower surface of the mounting seat 8 .

[0034] Preferably, an interface is provided on one side of the workbench 5 , and the interface and the EE-SPY401-1 type photoelectric sensor 2 are connected via a signal line.
