[0026] Specifically, two carrier platforms 4 are provided on the workbench 1, and the speaker cover and the plastic parts can be fixed on the carrier platforms 4 in sequence. The bending mechanism includes a pressing plate 5 and two bending assemblies 6, and the two bending assemblies 6 can simultaneously bend and compact the products on the two carrier platforms 4. Three first bending assemblies 62 are obliquely arranged at the bottom of the pressing plate 5, one of the first bending assemblies 62 is located obliquely above one end of the product, and the remaining two first bending assemblies 62 are located obliquely above the other end of the product.

Among them, the 18 positioning components 61, the three first bending components 62, the second bending component 63 and the third bending component 64 of the bending component 6 move downward to the specified position, and the 18 positioning components 61 first fix the various parts of the plastic part and press the plastic part onto the speaker cover, and then the three first bending components 62, the second bending component 63 and the third bending component 64 simultaneously bend the claws at different positions on the speaker cover, and compact the bent claws onto the plastic part, so as to fix the speaker cover and the plastic part together.

[0028] In the above structure, the first bending assembly 62 and the second bending assembly 63 are arranged obliquely, and the third bending assembly 64 is arranged horizontally, so that the clamps at different parts of the product are bent and compacted at the same time, which greatly improves the bending efficiency. The first bending assembly 62 and the second bending assembly 63 are arranged obliquely, and the third bending assembly 64 is arranged horizontally, which is not easy to cause crushing to the plastic parts and the clamps, thereby improving the yield rate of the combined product.

[0029] like Figure 2 As shown, in one embodiment, the first bending assembly 62 of the horn cover assembly bending device includes a first cylinder 621 and a first pressure rod 622. The first cylinder 621 is obliquely fixed at the bottom of the pressure plate 5, and the driving end of the first cylinder 621 is connected to the first pressure rod 622. The first cylinder 621 is used to drive the first pressure rod 622 to bend and compact the claws on the product from top to bottom.

The ends of the first pressing rod 622 are respectively provided with a bending surface and a compacting surface, and a certain angle is formed between the bending surface and the compacting surface. This setting not only improves the bending efficiency, but also is not easy to cause crushing to the plastic parts and the claws.

[0032] Specifically, the second cylinder 632 is connected to the bottom of the pressing plate 5 at an angle, the driving end of the second cylinder 632 is connected to the fixed plate 631, the fixed plate 631 is connected to the bottom of the pressing plate 5 through an inclined connecting plate, the fixed plate 631 and the inclined connecting plate are slidably matched, and the five second pressing rods 633 are respectively fixedly connected to the fixed plate 631, and the end of the fixed plate 631 close to the second cylinder 632 is higher than the end of the fixed plate 631 close to the pressing rod. The second cylinder 632 drives the fixed plate 631 to drive the five pressing rods to move obliquely from top to bottom along the connecting plate, so that the pressing rods simultaneously bend and compact the five claws on one side end of the horn cover. This setting effectively improves the bending efficiency and is not easy to cause crushing to the plastic parts and claws.

[0033] like Figure 4 As shown, in one embodiment, the third bending assembly 64 of the horn cover assembly bending device includes a push plate 641, a third cylinder 642 and a plurality of push rods 643, the push plate 641 is horizontally slidably matched with the bottom of the pressing plate 5, the third cylinder 642 is fixedly connected to the bottom of the pressing plate 5, the driving end of the third cylinder 642 is connected to the push plate 641, and a plurality of push rods 643 are vertically mounted on the push plate 641, respectively, and the third cylinder 642 is used to drive the push plate 641 to drive a plurality of push rods 643 to move horizontally to bend and compact the claws on the product. This setting effectively improves the bending efficiency and is not easy to cause crushing to the plastic parts and the claws.

[0034] Specifically, the third cylinder 642 is horizontally installed at the bottom of the pressing plate 5, the push plate 641 is connected to the bottom of the pressing plate 5 through a vertical connecting plate, the push plate 641 is slidably matched with the vertical connecting plate, the driving end of the third cylinder 642 is connected to the push plate 641, and the seven push rods 643 are respectively installed vertically and spaced on the push plate 641. The third cylinder 642 drives the push plate 641 to drive the seven push plates 641 to move horizontally to bend and compact the claws, so that the push rod 643 simultaneously bends and compacts the seven claws on the other side end of the horn cover. This setting effectively improves the bending efficiency and is not easy to cause crushing to the plastic parts and claws.

[0035] like Figure 5 As shown, in one embodiment, the positioning assembly 61 of the horn cover assembly bending device includes a connecting rod 611, a pressure head 612 and an elastic component 613, one end of the connecting rod 611 is slidably connected to the pressure plate 5, the other end of the connecting rod 611 is connected to the pressure head 612, the elastic component 613 is sleeved on the connecting rod 611, one end of the spring component abuts against the pressure plate 5, and the other end of the spring component abuts against the pressure head 612.

One end of the spring abuts against the pressure plate 5, and the other end of the spring abuts against the fixing ring. When the pressure head 612 fixes the plastic part, the pressure head 612 is forced to compress the spring, and the spring plays a buffering role. When the pressure head 612 is separated from the plastic part, the spring plays a role of resetting the pressure head 612. This setting facilitates the pressure head 612 to play a buffering role, and prevents the pressure head 612 from causing damage to the plastic part during the downward pressing process.

[0037] like Figure 1As shown, in one embodiment, the driving mechanism 2 of the horn cover assembly bending device is a fourth cylinder, which is installed at the bottom of the workbench 1, and the driving end of the fourth cylinder passes through the workbench 1 and is connected to the pressing plate 5. The fourth cylinder drives the pressing plate 5 to drive the two bending assemblies 6 to simultaneously bend and compact the products on the two carriers 4. This arrangement facilitates driving the pressing plate 5 to drive the bending assembly 6 to move up and down.

[0038] like Figure 1 As shown, in one embodiment, the support frame 3 of the speaker cover assembly bending device includes four guide pillars 31 and a fixing frame 32, one end of the four guide pillars 31 is respectively connected to the workbench 1, and the other end of the four guide pillars 31 is respectively connected to the fixing frame 32, and the pressing plate 5 is slidably connected to the four guide pillars 31 through guide sleeves 33. The setting of the guide pillars 31 facilitates the driving mechanism 2 to drive the pressing plate 5 to move up and down along the guide pillars 31.

When the fourth cylinder drives the pressing plate 5 to move downward, the first limiting posts 71 and the second limiting posts 72 are fixedly matched to limit the pressing plate 5.
