Description

Technical Field

[0001] This invention belongs to the field of preformed welding sheet production technology, specifically a speaker automatic mesh cover assembly equipment and its production process. Background Technology

[0002] As a common electronic device, audio equipment often requires a mesh cover before packaging or final assembly. This mesh cover is usually made of elastic woven material and primarily serves to protect against dust and scratches, as well as enhance the appearance. To ensure both aesthetics and functionality, the mesh cover must fit smoothly and tightly against the surface of the audio equipment casing, without any skewing or wrinkles.

[0003] Currently, this process mainly relies on manual labor. Operators must manually stretch the mesh cover before carefully aligning it with the speaker and fitting it in. This method has several drawbacks: First, manually stretching the mesh cover makes it difficult to ensure even pressure, easily leading to localized overstretching or difficulty in fitting; second, manual alignment is inefficient and prone to visual errors or operational instability, resulting in misaligned mesh covers, wrinkles, and affecting product appearance consistency; third, for speakers of different sizes, especially irregularly shaped speakers, the adaptability and precision of manual operation are even more difficult to guarantee, increasing operational difficulty and training costs; finally, repetitive manual operations are labor-intensive and inefficient, becoming a bottleneck restricting production capacity and quality stability in mass production. Therefore, there is a need to design an automatic mesh cover fitting device for speakers. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic speaker mesh cover assembly device and its manufacturing process to solve the above-mentioned problems, thereby resolving the issues mentioned in the background art.

[0005] To address the above problems, the present invention provides a technical solution: An automatic speaker mesh cover fitting device includes a base plate, a workbench fixedly mounted on the top of the base plate, a plurality of evenly distributed clamping blocks slidably connected to the top of the workbench, two symmetrically distributed support rods fixedly mounted on the top of the base plate and on the back of the workbench, a support plate fixedly mounted on the top of the two support rods, a cylinder fixedly mounted on the top of the support plate, the output end of the cylinder penetrating the support plate and slidably connected to the support plate, a spreading mechanism provided on the cylinder, a positioning mechanism provided on the clamping blocks, and a connecting mechanism provided on the clamping blocks.

[0006] Preferably, the opening mechanism includes a bracket, with the lower end of the cylinder output end fixedly mounted on the bracket, a fixed plate fixedly mounted on the bottom of the bracket, and an electric push rod fixedly mounted on the top of the fixed plate. The output end of the electric push rod passes through the fixed plate and is slidably connected to it. A connecting plate is fixedly mounted on the lower end of the electric push rod output end. Multiple evenly distributed hinge blocks are fixedly mounted on the bottom of the connecting plate. A hinge rod is hinged to the outer side of each hinge block, and a hinge seat is hinged to the outer side of each hinge rod. The hinge seat is fixedly mounted on the bottom of the fixed plate. A connecting rod is fixedly mounted to the outer side of each hinge rod, and a support block is fixedly mounted to the outer side of the connecting rod. This opening mechanism facilitates the automatic opening and installation of the mesh cover.

[0007] Preferably, two symmetrically distributed guide posts are fixedly installed on the top of the bracket, the guide posts penetrating the support plate and slidably connected to the support plate. By designing the guide posts, the movement of the bracket can be guided.

[0008] Preferably, the positioning mechanism includes a drive motor, which is fixedly installed inside the worktable. A screw is fixedly installed at the upper end of the output end of the drive motor. A slide plate is threadedly connected to the outer side of the screw. Multiple guide rods are fixedly installed on the top of the slide plate and are slidably connected to the worktable. A guide block is fixedly installed on the top of the guide rod and is slidably connected to the worktable. A ball bearing is movably sleeved inside the guide block and is slidably connected to the worktable. Multiple top blocks are fixedly installed at the upper end of the slide plate. An inclined block is slidably connected to the outer side of the top block and is slidably connected to the worktable. A crossbar is slidably sleeved inside the inclined block and is fixedly connected to the worktable. The inclined block contacts a clamping block. By designing this positioning mechanism, the workpiece can be automatically clamped and positioned.

[0009] Preferably, the worktable has a groove inside, and a ball bearing is slidably connected inside the groove. By designing the groove, the ball bearing can slide along the groove.

[0010] Preferably, the connecting mechanism includes a push rod, which is slidably sleeved inside the clamping block. A slider is fixedly connected to the inner side of the push rod, and the slider is slidably connected to both the clamping block and the inclined block. A sliding rod is fixedly connected to the outer side of the slider, and the sliding rod is slidably connected to the clamping block. A spring is provided on the outer side of the sliding rod, with one end fixedly connected to the slider and the other end fixedly connected to the clamping block. A magnet is fixedly installed on the inner sidewall of the clamping block. A magnetic block is fixedly installed on the outer side of the slider and below the sliding rod. An insert block is fixedly installed on the end of the slider away from the magnetic block, and the insert block is slidably connected to the inclined block. This connecting mechanism facilitates the disassembly and replacement of the clamping block.

[0011] Preferably, the inclined block has a slot inside, and an insert block is slidably connected inside the slot. By designing the slot, the insert block can slide inside the slot.

[0012] A manufacturing process for an automatic speaker mesh cover installation device, applied to the aforementioned automatic speaker mesh cover installation device, includes the following steps: Step 1: First, place the speaker on the top of the workbench. Then, start the drive motor. The output of the drive motor drives the screw to rotate, causing the slide plate to make a spiral motion. The slide plate drives the guide rod and guide block to move upward. The guide block drives the ball to slide along the slide groove. At the same time, the slide plate drives the top block to move upward. The top block will slide along the inclined surface of the inclined block. The inclined block will slide along the crossbar when it is squeezed. At the same time, the inclined block drives the clamping block to move. Multiple clamping blocks move towards the speaker. Finally, the clamping blocks contact the speaker, which realizes the automatic positioning of the speaker. Step 2: Place the mesh cover on the outside of the support block, then activate the electric push rod. The output end of the electric push rod drives the connecting plate to move down, the connecting plate drives the hinge block to move down, the hinge block pushes the hinge rod to deflect and causes the hinge rod to deflect along the hinge seat. The hinge rod drives the connecting rod to deflect, and the connecting rod can drive the support block to deflect outward. The support block will automatically open the mesh cover. Then activate the cylinder. The output end of the cylinder drives the bracket to move down, the bracket drives the guide post to move down along the support plate, and then the opened mesh cover can be placed on the outside of the speaker. Step 3: When it is necessary to remove the clamping block, push the push rod inward. The push rod will push the slider to move horizontally, and the slider will drive the slide rod to move horizontally. The slider will compress the spring, and the slider will also drive the insert block to move horizontally. At the same time, the slider will drive the magnetic block to move horizontally. After the magnetic block is attracted to the magnet, the insert block will slide out from the inside of the slot. Then the clamping block can be removed from the inclined block. Then the clamping blocks of different shapes and sizes can be replaced and used.

[0013] The beneficial effects of this invention are as follows: This invention relates to an automatic speaker mesh cover fitting device, which features automatic opening and fitting of the mesh cover and convenient automatic positioning for speakers of different shapes and sizes. In practical use, compared with traditional automatic speaker mesh cover fitting devices, this automatic speaker mesh cover fitting device has the following beneficial effects: First, by designing the function of the electric push rod, the output end of the electric push rod can drive the connecting plate to move down, the connecting plate can drive the hinge block to move, and the hinge block can push the hinge rod to deflect along the hinge seat, which in turn can push the connecting rod and the support block to deflect outward. Through the synchronous deflection of multiple support blocks, the mesh cover can be automatically and conveniently opened, making it convenient to put the mesh cover on. Secondly, by designing the function of the drive motor, the output end of the drive motor can drive the screw to rotate, thereby realizing the spiral movement of the slide plate. The movement of the slide plate can drive the top block to move, and the movement of the top block can push the inclined block to move horizontally, thereby realizing the synchronous movement of multiple clamping blocks. This enables multi-directional synchronous automatic clamping of the audio equipment, making it convenient and quick to use. Finally, by designing the insertion and engagement of the plug and slot, the clamp can be limited, thereby achieving the connection and fixation of the clamp and the inclined block. When the push rod is moved horizontally, the plug and slot can be separated, and the clamp can be removed from the inclined block. This allows for easy disassembly and replacement of clamps of different shapes and sizes, and is suitable for clamping and positioning different shaped speakers. Attached Figure Description

By designing the connecting mechanism 9, it is convenient to disassemble and replace the clamping block 3.

[0021] A manufacturing process for an automatic speaker mesh cover installation device includes the following steps: Step 1: First, place the speaker on top of workbench 2 (the surface is equipped with a rubber buffer pad to prevent scratches on the speaker shell). Then, start the drive motor 81 (a servo motor is selected to achieve precise control of the number of rotations and accuracy). The output end of the drive motor 81 drives the screw 82 to rotate (a precision ball screw is used, which has high transmission efficiency and is self-locking), causing the slide plate 83 to perform a threaded motion. The slide plate 83 drives the guide rod 84 and the guide block 85 to move upward. The guide block 85 drives the ball 86 to slide along the slide groove 87. Simultaneously, the sliding plate 83 moves the top block 88 upward, and the top block 88 slides along the inclined surface of the inclined block 89. The inclined block 89, when squeezed, slides along the crossbar 891 (the inclined surface is finely ground and coated with grease to reduce friction). At the same time, the inclined block 89 moves the clamping block 3, and multiple clamping blocks 3 move towards the speaker (the inner lining is made of soft polyurethane or silicone, which provides sufficient friction and avoids indentation). Finally, the clamping blocks 3 come into contact with the speaker, thus achieving automatic positioning of the speaker. Step Two: Place the mesh cover on the outside of the support block 791 (the edges need to be fully rounded and polished to prevent snagging). Then, activate the electric push rod 74. The output end of the electric push rod 74 drives the connecting plate 75 to move down. The connecting plate 75 drives the hinge block 76 to move down. The hinge block 76 will push the hinge rod 77 to deflect and cause the hinge rod 77 to deflect along the hinge seat 78. The hinge rod 77 will drive the connecting rod 79 to deflect, and the connecting rod 79 can then drive the support block 791 to deflect outward. (Each hinge point is equipped with...) With wear-resistant bushings to extend the life of the motion mechanism, the support block 791 will automatically open the mesh cover (the mesh cover material is usually made of elastic knitted fabric, and its stretch rate must match the expansion stroke). Then the cylinder 6 is activated (the air intake circuit is equipped with a speed control valve to achieve adjustable downward speed). The output end of the cylinder 6 drives the bracket 71 to move downward, and the bracket 71 drives the guide post 72 to move downward along the support plate 5 (the surface is chrome-plated and hardened, and lubricated regularly). Then the opened mesh cover can be placed on the outside of the speaker. Step 3: When it is necessary to remove clamp 3, push the push rod 91 inward (the surface is designed with anti-slip texture for easy operation). The push rod 91 pushes the slider 92 to move horizontally, and the slider 92 drives the slider rod 93 to move horizontally. The slider 92 will compress the spring 94 (made of stainless steel and pre-compressed to ensure stable elasticity). The slider 92 will also drive the insertion block 97 to move horizontally. At the same time, the slider 92 drives the magnetic block 96 to move horizontally. After the magnetic block 96 is attracted to the magnet 95 (preferably using neodymium iron boron permanent magnets to ensure firm attraction), the insertion block 97 will slide out from the inside of the slot 98 (using H7 / g6 clearance fit to ensure smooth sliding and accurate positioning). Then, clamp 3 can be removed from the inclined block 89, and clamp 3 of different shapes and sizes can be replaced. (This design realizes modular quick replacement, which is convenient for adapting to different models of speaker products).
