Description

Technical Field

[0001] The invention mainly relates to the technical field of speaker production, and in particular to a glue coating device for speaker production. Background Art

[0002] The speaker is a transducer device that converts sound into electricity. It is mainly composed of a washer, a magnet, a bracket, tuning paper, and a mesh. Since the speaker itself is not waterproof, a speaker waterproof film needs to be installed at the corresponding position of the shell before installation to achieve waterproofing. After the speaker is installed, a waterproof sealant will be used to seal the edges to prevent water from entering the interior of the electronic product.

[0003] In the prior art, gluing of speakers is semi-automatically performed. First, the speaker parts are manually placed in the limiting groove, and then the moving arm is controlled to drive multiple glue nozzles to move to the top of the speaker parts for gluing. After the gluing is completed, the parts with glue are manually taken out, and then new speaker parts are placed, and then the new speaker parts are fixed, and then the moving arm is operated to glue again. However, in this process, manual operation is cumbersome, resulting in low efficiency of speaker gluing. Therefore, a new gluing device for speaker production is needed. Summary of the invention

[0009] Preferably, the telescopic member comprises a rectangular tube, which is rotatably connected to the annular surface of the round rod, and hinged rods are inserted at both ends of the rectangular tube, the upper hinged rod is hinged to the slide plate, and the lower hinged rod is hinged to two second supporting rods.

[0010] Preferably, a supporting block is provided on one side of the limiting groove close to the center of the bottom plate, an extrusion groove with a parallelogram cross-section is opened on the lower surface of the supporting block, an L-shaped rod is installed on the annular surface of the first supporting rod, an extrusion block is installed on the end of the L-shaped rod away from the first supporting rod, and the extrusion block is slidably connected in the extrusion groove.

[0011] Preferably, a pressure plate is hinged on the upper surface of the extrusion block, and extension plates are installed on both sides of the upper surface of the skateboard. A rectangular groove is provided on the lower surface of the extension plate away from the skateboard, and a rectangular plate is inserted in the rectangular groove. The rectangular plate is in sliding contact with the pressure plate, and an elastic member is installed at one end of the rectangular plate in the rectangular groove, and the end of the elastic member away from the rectangular plate is installed in the rectangular groove.

[0012] Preferably, one side of the limiting sleeve close to the edge of the bottom plate is hinged in the limiting groove.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0022] Please refer to the attached Figure 1-Figure 3 A gluing device for speaker production includes a connecting plate 1 installed on a moving arm, a plurality of glue spray nozzles 2 are installed on the end of the connecting plate 1 away from the moving arm, a bottom plate 4 is provided on the lower surface of the glue spray nozzle 2, a plurality of limiting grooves are provided on the left and right sides of the upper surface of the bottom plate 4, speaker parts to be glued are arranged in the limiting grooves, a limiting sleeve 9 is arranged in the limiting groove, and a side of the limiting sleeve 9 away from the center of the bottom plate 4 is connected to the limiting groove.

[0023] An L-shaped groove is opened in the limiting groove, and an L-shaped tube 12 is arranged in the L-shaped groove. The L-shaped tube 12 is filled with hydraulic oil. The first supporting rod 10 is inserted into the end of the L-shaped tube 12 facing the limiting sleeve 9, and the end of the first supporting rod 10 away from the L-shaped tube 12 is in contact with the limiting sleeve 9, and then the second supporting rod 13 is inserted into the end of the L-shaped tube 12 away from the limiting sleeve 9. Pistons 11 are installed at one end of the first supporting rod 10 and the second supporting rod 13 in the L-shaped tube 12.

[0024] A groove is opened at the center of the upper surface of the bottom plate 4, and a slide groove is opened near the opening on the front and rear sides of the groove. A slider is slidably connected in the slide groove, and then a slide plate 6 is installed between multiple sliders. A connecting rod 7 is installed on the lower surface of the connecting plate 1. When the moving arm drives the multiple glue nozzles 2 on the connecting plate 1 to move, the slide plate 6 can be driven to move in the groove, and then a round rod 16 is installed on the front and rear sides of the groove. The annular surface of the round rod 16 is rotatably connected to the rectangular tube 15. Both ends of the rectangular tube 15 are connected with hinged rods 14. The upper hinged rod 14 is hinged to the slide plate 6, and the lower hinged rod 14 is hinged to the two second supporting rods 13.

[0025] When the glue spraying nozzle 2 moves to one side to spray glue, the telescopic structure composed of the rectangular tube 15 and the hinged rod 14 squeezes the squeezing structure on the other side, pushing the glue-coated speaker part out of the limiting groove, thereby reducing the operation steps of the workers and improving work efficiency.

[0026] A supporting block 8 is arranged on one side of the limiting groove near the center of the bottom plate 4, and an extrusion groove with a parallelogram cross-section is opened on the lower surface of the supporting block 8. An L-shaped rod 20 is installed on the annular surface of the first supporting rod 10, and an extrusion block 19 is installed at one end of the L-shaped rod 20 away from the first supporting rod 10, and the extrusion block 19 is slidably connected in the extrusion groove.

[0027] When the glue spray nozzle 2 moves to this side again, it drives the extrusion structure to separate from the limiting groove, and makes the holding structure move to the side away from the center of the bottom plate 4 to limit and fix the speaker parts to be glued placed in the limiting groove, so as to avoid the speaker parts to be glued being tilted when placed in the limiting groove.

[0028] The pressure plate 5 is hinged on the upper surface of the extrusion block 19, and extension plates 3 are installed on both sides of the left and right sides of the upper surface of the slide plate 6. A rectangular groove is provided on the lower surface of the extension plate 3 away from the slide plate 6, and a rectangular plate 18 is inserted in the rectangular groove. The rectangular plate 18 is in sliding contact with the pressure plate 5. An elastic member 17 is installed at one end of the rectangular plate 18 in the rectangular groove. The elastic member 17 is a spring. The elastic member 17 is in a compressed state, and one end of the elastic member 17 away from the rectangular plate 18 is installed in the rectangular groove.

[0029] By installing a pressing plate 5 on the upper surface of the pressing structure, the glue spray nozzle 2 is used to move the extension plate 3 and the rectangular plate 18 to the pressing plate 5 on the side of the limiting sleeve 9, and the pressing plate 5 is pressed to press and fix the speaker parts to be glued. Since the pressing plate 5 is hinged on the upper surface of the supporting block 8, when the supporting block 8 moves away from the limiting sleeve 9, the pressing plate 5 moves away from the limiting sleeve 9 together with the supporting block 8, and the slide plate 6 drives the extension plate 3 and the rectangular plate 18 to move away from the limiting sleeve 9 at a faster speed, so that the rectangular plate 18 squeezes the side of the pressing plate 5 away from the limiting sleeve 9, so that the side of the pressing plate 5 away from the limiting sleeve 9 is tilted, thereby not affecting the removal and placement of the speaker parts.

[0030] The specific operation process of the present invention is as follows: the initial position of the abutment block 8 is set on a side close to the center of the bottom plate 4. At this time, there is enough space in the limiting groove to place the speaker parts to be glued. Then the arm is moved to drive the connecting plate 1 and multiple glue nozzles 2 to move toward the limiting groove on the glue coating side. During the movement, the connecting plate 1 drives the slide plate 6 to move toward the limiting groove on the glue coating side through the connecting rod 7. At this time, the telescopic structure composed of the rectangular tube 15 and the hinged rod 14 deflects toward the limiting groove away from the glue coating side, and at the same time drives the second abutment rod 13 on this side to move away from the limiting groove on the glue coating side. When the second supporting rod 13 moves, it drives the first supporting rod 10 to move into the L-shaped tube 12. The first supporting rod 10 moves into the L-shaped tube 12, drives the L-shaped rod 20 to move downward and squeeze the extrusion groove, so that the supporting block 8 moves toward the limiting sleeve 9, and squeezes the speaker parts to be glued placed on the limiting sleeve 9, thereby limiting and fixing their positions. When the slide plate 6 moves, it drives the extension plate 3 and the rectangular plate 18 to squeeze the end of the pressure plate 5 close to the limiting sleeve 9, so that the pressure plate 5 limits the position of the speaker parts to be glued, thereby avoiding shaking during gluing.

[0031] When the gluing of the speaker part on one side is completed, the moving arm drives the connecting plate 1, multiple glue nozzles 2 and the slide plate 6 to move to the other side. At this time, the telescopic structure deflects the side of the speaker part that has been glued, and drives the second supporting rod 13 on this side to move into the L-shaped tube 12 and squeeze the first supporting rod 10 through hydraulic oil, so that the first supporting rod 10 lifts the limiting sleeve 9 and pushes the speaker part out of the limiting groove, thereby reducing the workers' operating steps and improving work efficiency.

[0032] And when the first supporting rod 10 moves upward, the L-shaped rod 20 moves upward to drive the supporting block 8 to move toward the side away from the limiting sleeve 9, so that the space in the limiting groove is increased, which is convenient for placing the uncoated speaker parts in the limiting groove. At the same time, since the pressure plate 5 is installed on the upper surface of the supporting block 8, when the supporting block 8 is away from the limiting sleeve 9, the pressure plate 5 also moves away from the limiting sleeve 9. At the same time, the slide plate 6 drives the extension plate 3 and the rectangular plate 18 to move toward the side away from the limiting sleeve 9, and squeezes the pressure plate 5 away from the side of the limiting sleeve 9, so that the pressure plate 5 is tilted, which is more convenient for placing the speaker parts in the limiting groove.

[0033] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
