Description

Technical Field

[0001] This utility model relates to the field of dispensing fixture technology, specifically to a dispensing fixture for processing speaker shells. Background Technology

[0002] A dispensing fixture is an auxiliary tool used in the automated dispensing process. It is used to fix and position the parts that need to be dispensed to ensure the accuracy and consistency of the dispensing. Dispensing fixtures can be customized according to the requirements of the dispensing process to adapt to different dispensing applications and production environments.

[0003] During the adhesive application process for speaker enclosures, the adhesive must be applied evenly and in equal amounts to the enclosure material to ensure stable adhesion. If the amount of adhesive applied varies each time, it can lead to adhesive overflow in some areas and insufficient adhesive in others, resulting in weak adhesion and affecting the stability of the speaker enclosure after bonding. Furthermore, the speaker enclosure is a crucial component for ensuring sound quality is not compromised; gaps between the panels after bonding will also affect the speaker's sound performance.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0017] Please see Figure 1-3This utility model provides a technical solution: including a processing table 1, with support frames 11 fixed on both sides of the upper end of the processing table 1, a slide rail 2 fixed on the upper end of the support frame 11, a track block 3 slidably connected on the slide rail 2, a glue sleeve 4 fixed on the front side of the track block 3, an injection pipe 5 fixed on the outer side of the glue sleeve 4, a glue head 6 fixed on the bottom of the glue sleeve 4, a partition plate 41 fixed horizontally inside the glue sleeve 4, an inner sleeve 42 fixed on the upper end of the partition plate 41, a connecting hole 44 opened at the bottom of the inner sleeve 42, a metering groove 43 provided inside the inner sleeve 42, a piston plate 45 slidably connected inside the metering groove 43, a positioning sleeve 7 installed inside the metering groove 43 and above the piston plate 45, a discharge pipe 47 fixed on the partition plate 41 and aligned with the metering groove 43, a one-way valve installed in the connecting hole 44, a solenoid valve fixed on the discharge pipe 47, a regulating valve fixed on the glue head 6, and a telescopic cylinder 46 fixed on the upper end of the glue sleeve 4, with the output end of the telescopic cylinder 46 fixed on the piston plate 45.

[0018] A threaded rod 21 is rotatably connected inside the slide rail 2. The threaded rod 21 passes through the track block 3 and is threadedly connected to the track block 3. A stepper motor 22 and a controller 23 that drive the threaded rod 21 to rotate are fixed on the outside of the support frame 11.

[0019] A pair of connecting rods 71 ​​are fixed to the upper end of the positioning sleeve 7. The upper end of the connecting rod 71 extends out of the adhesive sleeve 4. A fixing block 73 is fixed to the upper end of the adhesive sleeve 4 and at a position corresponding to the connecting rod 71. A positioning rod 74 is installed on the side of the fixing block 73 near the connecting rod 71. A set of positioning grooves 72 are equidistantly opened on the outer side of the connecting rod 71. The end of the positioning rod 74 is inserted into one of the positioning grooves 72. A telescopic spring 75 is fixed between the inner side wall of the fixing block 73 and the positioning rod 74. A pull block 76 is slidably connected to the upper end of the fixing block 73. The pull block 76 is fixedly connected to the end of the positioning rod 74.

[0020] Working principle: First, connect the entire device to an external power source. Driven by the stepper motor 22, the threaded rod 21 rotates, causing the track block 3 to slide on the slide rail 2. Simultaneously, glue is injected from the injection tube 5 into the dispensing sleeve 4 and then extruded from the dispensing head 6, achieving the purpose of dispensing glue onto the speaker shell on the processing table 1. During this process, the up-and-down extension of the connecting rod 71 drives the positioning sleeve 7 to extend and retract, changing the position of the positioning sleeve 7 within the metering groove 43. This alters the maximum upward movement of the piston plate 45, ultimately changing the amount of glue entering the metering groove 43 in a single operation, thus achieving the purpose of adjusting the volume of glue in the metering groove 43. When the glue enters the dispensing sleeve 4, it will enter the metering tank 43 through the connecting hole 44. After the metering tank 43 is full, the solenoid valve on the discharge pipe 47 is opened, and the piston plate 45 is driven downward by the telescopic cylinder 46 to squeeze out the glue in the metering tank 43. Then the next dispensing is performed. Since the amount of glue entering the metering tank 43 is always the same, the amount of glue dispensed each time can be guaranteed to be the same. When fixing the positioning sleeve 7, the telescopic spring 75 can be used to push the positioning rod 74 out from the fixing block 73 and insert it into the positioning groove 72 to fix the connecting rod 71, thereby fixing the positioning sleeve 7.
