Description

Technical Field

[0001] The present invention relates to the technical field of loudspeakers, and in particular to a diaphragm assembly device for loudspeakers. Background Art

[0002] A speaker is a transducer device that converts electrical signals into sound signals. Speakers on the market are generally diaphragm structures. The diaphragm is a thin and sensitive circular diaphragm located inside the speaker. The diaphragm is usually made of paper, plastic, synthetic fiber or metal. The diaphragm responds to incoming electrical signals, generates tiny vibrations and converts these vibrations into sound waves. The voice coil of the speaker amplifies these sound waves and transmits them to the user's ears.

[0003] Therefore, the assembly of the diaphragm is a relatively important process in the speaker production process. However, due to reasons such as static electricity, the diaphragm is prone to adhesion, which makes it easy to take out multiple diaphragms at a time. Manual assistance is often required to separate the diaphragms. However, the diaphragm is thin and easy to be damaged, making it difficult to separate. Manual separation is time-consuming and labor-intensive, and production efficiency is low. Summary of the invention

[0004] The purpose of the present invention is to provide a diaphragm assembly device for a loudspeaker, aiming to improve the problem that the diaphragm is difficult to separate and the production efficiency is low during the existing loudspeaker production.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances. Example

[0056] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, this embodiment provides a diaphragm assembly device for a loudspeaker, including a conveyor belt 10, a material storage mechanism 11, a diaphragm carrier plate 12, a separation mechanism 13 and a transplanting mechanism 14.

[0057] The diaphragm carrier plate 12 is arranged between the storage mechanism 11 and the conveyor belt 10, and is used to place the diaphragm to be assembled on the semi-finished speaker. The conveyor belt 10 is provided with at least one assembly tray 101, which is used to place the semi-finished speaker. The transfer mechanism 14 includes a second support frame 141 that elevates itself. The transfer mechanism 14 is used to transfer the diaphragm on the diaphragm carrier plate 12 to the semi-finished speaker on the assembly tray 101 to complete the assembly.

[0058] In addition, the storage mechanism 11 includes a placement frame 111, a storage box 112 and a separation plate 113. The placement frame 111 is provided with a slot 1113 for placing the storage box 112. The storage box 112 is provided with at least one diaphragm slot 1121, and the diaphragms are stacked and stored in the diaphragm slot 1121. The separation plate 113 is arranged on the top surface of the storage box 112, and the separation plate 113 is provided with a threaded opening 1131 arranged in alignment with the notch of the diaphragm slot 1121. The separation mechanism 13 includes a first support frame 131 for raising itself, a first suction cup unit 132, a first lifting power unit 133 for driving the first suction cup unit 132 to move up and down, and a first horizontal power unit 134 for driving the first lifting power unit 133 to move back and forth between the diaphragm carrier 12 and the storage mechanism 11. Specifically, the first suction cup unit 132 is composed of at least one vacuum suction nozzle, the first lifting power unit 133 and the first horizontal power unit 134 are motors or cylinders, and an optional first lifting power unit 133 and the first horizontal power unit 134 are SE100X25 cylinders. Driven by the first lifting power unit 133 and the first horizontal power unit 134, the first suction cup unit 132 can be driven to adsorb the diaphragm in the diaphragm groove 1121, and after adsorbing the diaphragm, the first suction cup unit 132 is driven to shake up and down at the threaded mouth 1131 of the separation plate 113, and the threaded structure of the threaded mouth 1131 is used to separate the diaphragms that are stuck together, so that each vacuum suction nozzle of the first suction cup unit 132 can only take away one diaphragm at a time, and then the first suction cup unit 132 transfers the diaphragm to the diaphragm carrier 12 for the next assembly process of the speaker semi-finished product, thereby realizing the automation of diaphragm separation, improving production efficiency and reducing labor costs, and having good practicality.

[0059] Furthermore, the threaded structure of the threaded opening 1131 is a continuous protrusion in a spiral shape with a triangular cross-section made on a cylindrical surface. When the first suction cup unit 132 adsorbs the diaphragm at the threaded opening 1131 and shakes up and down, the diaphragm shakes up and down and comes into contact with the threaded structure. The protrusion with a triangular cross-section can be used to quickly peel off the adhered diaphragm, and the continuous threaded structure makes the edge of the diaphragm evenly stressed and not easily damaged, and can also peel off the adhered diaphragm more quickly.

[0060] like Figure 5 and Figure 6 As shown, in this embodiment, two slots 1113 are provided, and the two slots 1113 are symmetrically arranged on the placement rack 111. A rotating power unit 1112 is arranged in the middle of the placement rack 111 to drive the placement rack 111 to rotate. The rotating power unit 1112 can be a motor or a cylinder. An optional rotating power unit 1112 is a HG-KR053 rotating servo motor.

[0061] Specifically, a storage box 112 that can accommodate a sufficient number of membranes is placed on a slot 1113 close to the membrane carrier 12 to facilitate the separation mechanism 13 to transfer the membranes to the membrane carrier 12, and the slot 1113 arranged on the other side of the placement rack 111 is used to place another replenishment storage box 112. When the membranes in a storage box 112 are used up, the rotation power unit 1112 is used to drive the placement rack 111 to rotate, and the other storage box 112 is rotated to the side close to the membrane carrier 12, thereby saving material replacement time, ensuring continuous production, and improving production efficiency.

[0062] like Figure 5 and Figure 6 As shown, in this embodiment, a pressing piece 1111 is provided on the placement rack 111 to press against one side of the material storage box 112.

[0063] Specifically, after the material storage box 112 is placed on the slot 1113, the slot 1113 is clamped to fix the two sides of the material storage box 112, but in order to facilitate the material storage box 112 to be taken for material change, there is a certain small gap between the slot 1113 and the material storage box. In order to further fix the material storage box 112 during the production process, the handle of the top pressure piece 1111 is rotated so that the top pressure piece 1111 pushes against one side of the material storage box 112. At this time, the slot 1113 pushes against the other side of the material storage box 112, thereby achieving a tight clamping of the material storage box 112, avoiding the situation that the material storage box 112 shakes during the production process, and ensuring the stability of the material storage box 112. When the diaphragm in the material storage box 112 is exhausted, the top pressure piece 1111 can be released to take out the material storage box 112, which is convenient for material change.

[0064] like Figure 4 , Figure 5 and Figure 6 As shown, the present embodiment also includes an infrared sensor 15. The top of the storage box 112 is provided with a monitoring through hole 1122 that penetrates the storage box 112 and the diaphragm slot 1121. The detection beam of the infrared sensor 15 is arranged in alignment with the monitoring through hole 1122. An optional infrared sensor 15 is a PM-K54 opposing infrared photoelectric sensor. The detection beam of the infrared sensor 15 passes through the monitoring through hole 1122 to monitor the remaining amount of the diaphragm in the storage box 112. When the remaining amount of the diaphragm in the storage box 112 is insufficient, the infrared sensor 15 will transmit a signal or trigger the rotating power unit 1112 to drive the placement rack 111 to rotate, thereby reversing the position of the storage box 112 on the two card slots 1113, realizing automatic material replacement and improving production efficiency.

[0065] like Figure 5 and Figure 6As shown, this embodiment also includes a lifting mechanism 16, which includes at least one lifting member 161 and a lifting power unit 162 that drives the lifting member 161 to move up and down; the bottom of the diaphragm groove 1121 is provided with a lifting hole (not shown in the figure) aligned with the lifting member 161. An optional lifting power unit 162 is an SC63-100S cylinder. The lifting member 161 can extend into the diaphragm groove 1121 from the lifting hole, and under the drive of the lifting power unit 162, the diaphragm in the diaphragm groove 1121 is lifted up, so that the first suction cup unit 132 can adsorb the diaphragm in the diaphragm groove 1121.

[0066] like Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, handle grooves 1123 are provided on the two opposite sides of the material storage box 112, and the handle grooves 1123 are located at the top of the material storage box 112. Holding the handle grooves 1123 can facilitate taking and placing the material storage box 112, so as to facilitate material replacement.

[0067] like Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, observation windows 1124 that penetrate the diaphragm groove 1121 are arranged on the two opposite sides of the storage box 112. The observation windows 1124 are located in the middle and bottom of the storage box 112. The situation in the diaphragm groove 1121 can be easily observed through the observation windows 1124.

[0068] like Figure 2 , Figure 3 and Figure 7 As shown, in this embodiment, the transplanting mechanism 14 also includes a second suction cup unit 142, a second lifting power unit 143 that drives the second suction cup unit 142 to move up and down, and a second horizontal power unit 144 that drives the second lifting power unit 143 to move back and forth between the film carrier 12 and the assembly material tray 101. Among them, the second suction cup unit 142 is composed of at least one vacuum suction nozzle, and the second lifting power unit 143 and the second horizontal power unit 144 can be a motor or a cylinder. An optional second lifting power unit 143 and the second horizontal power unit 144 are SE100X25 cylinders.

[0069] like Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, the present embodiment also includes a lifting mechanism 17, which is located directly below the conveyor belt 10 and is arranged in alignment with the diaphragm carrier 12. The lifting mechanism 17 includes a negative pressure plate 173, a lifting plate 171, a first lifting power unit 172 that drives the lifting plate 171 to move up and down, and a second lifting power unit 174 that drives the negative pressure plate 173 to move up and down. An optional first lifting power unit 172 and a second lifting power unit 174 are LEY electric cylinders; there are two lifting plates 171, and the two lifting plates 171 are arranged on both sides of the negative pressure plate 173; a plurality of negative pressure suction cups 1731 are arranged on the negative pressure plate 173; a positioning sensor 102 that is arranged in alignment with the diaphragm carrier 12 is arranged on the conveyor belt 10, and when the positioning sensor 102 detects the assembly tray 101, it triggers the first lifting power unit 172 to drive the lifting plate 171 to rise, and triggers the second lifting power unit 174 to drive the negative pressure plate 173 to rise. The lifting plate 171 is used to lift the assembly tray 101, so that the assembly tray 101 leaves the conveyor belt 10 and stops conveying to facilitate the assembly process. After the negative pressure plate 173 is raised, the negative pressure suction cup 1731 on the negative pressure plate 173 corresponds one-to-one with the semi-finished speaker on the assembly tray 101. When the diaphragm is assembled onto the semi-finished speaker, the negative pressure suction cup 1731 can firmly adsorb the diaphragm to complete the assembly.

[0070] like Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, in this embodiment, at least one positioning notch 1011 is provided on the side of the assembly tray 101; and a positioning block 1711 adapted to the positioning notch 1011 is provided on the top surface of the lifting plate 171. The positioning block 1711 extends into the positioning notch 1011 to limit the assembly tray 101, thereby ensuring the stability of the assembly tray 101 during the assembly process.

[0071] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
