Detailed Implementation

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0031] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0032] Reference Figures 1-6 An EVA pad mounting device for speaker manufacturing, comprising:

[0033] Workbench 1, wherein a rotating support platform 2 is provided on the upper surface of the workbench 1;

[0034] Fixture 3, several fixtures 3 are provided and several fixtures 3 are set on the rotating support table 2. Each fixture 3 has an installation groove at the upper end to facilitate manual application of EVA pad film inside it. In practice, the side of the EVA pad film without glue is applied to the installation groove at the upper end of the fixture 3, which makes the application easier. After application, the glue side of the EVA pad film is facing up, and the protective film on the glue side can be peeled off.

[0035] Support platform rotation control assembly 4, which is located below the worktable 1 and is used for horizontal rotation control of the rotating support platform 2;

[0036] A transverse sliding rail assembly 5, wherein the transverse sliding rail assembly 5 is horizontally installed via a mounting column assembly 6 that is vertically fixed on the worktable 1; and

[0037] A lifting base assembly 7 is slidably mounted on the transverse sliding rail assembly 5. A cylinder gripper 8 is mounted on the movable end of the lifting base assembly 7. A flip clamping assembly 9 is mounted on the cylinder gripper 8. In practice, the operator and the assembly line equipped with the speaker are located on opposite sides of the support platform rotation control assembly 4. This allows the operator to first attach the EVA pad to the fixture 3. Then, after the support platform rotation control assembly 4 is rotated, the flip clamping assembly 9 grabs the fixture 3, flips it, and presses the EVA pad located at the lower end of the fixture 3 toward the speaker. This allows the EVA pad to be fully adhered to the speaker with glue. After that, the flip clamping assembly 9 controls the fixture 3 to flip and place it on the support platform rotation control assembly 4.

[0038] By installing a horizontally rotating support platform 2 on the set workbench 1, the rotating support platform 2 achieves horizontal rotation under the rotation control of the support platform rotation control component 4, thereby performing a rotational operation on the corresponding fixture 3. This allows the operator to place EVA pads in the mounting slots of each fixture 3, and then rotate it to the underside of the transverse moving slide rail assembly 5. By installing the cylinder gripper 8 on the lifting base assembly 7 slidably set on the transverse moving slide rail assembly 5, the fixture 3 on the rotating support platform 2 is grasped and linearly transported. The cylinder gripper 8 rotates 180° under the action of the flipping clamping component 9, causing the EVA pad 34 placed on the fixture 3 to flip and engage with the speaker to be processed, thereby realizing the stamping and installation of the EVA pad 34. Thus, the installation of the EVA pad 34 can be achieved through an automated operation, ensuring processing efficiency and accuracy. The manual operation part of the whole process is simpler and easier. In addition, the operation of the EVA pad installation equipment does not affect the manual operation, thus greatly improving work efficiency.

[0039] Preferably, the support platform rotation control assembly 4 includes a rotating motor 10 and a worm gear unit 11 fixed below the worktable 1. The rotating motor 10 and the input end of the worm gear unit 11 are connected by a belt 12. The input end of the worm gear unit 11 is vertically arranged and fixedly connected to the center of the rotating support platform 2.

[0040] like Figure 4As shown, the support platform rotation control assembly 4 is fixedly installed below the workbench 1 to transmit power for rotating the support platform 2. More specifically, the support platform rotation control assembly 4 includes a rotating motor 10 and a worm gear unit 11, which are connected by a belt for rotational transmission. Simultaneously, the worm gear unit 11 enables the reversal of the rotation direction. After the output end of the worm gear unit 11 is fixedly connected to the rotating support platform 2, it provides control for the horizontal rotation of the support platform 2.

[0041] Preferably, the transverse sliding rail assembly 5 includes a mounting plate 13, a guide plate 14 disposed on the mounting plate 13, and a lead screw assembly 33 disposed on the mounting plate 13. The mounting column assembly 6 includes a vertically disposed first mounting column 15 and a second mounting column 16. One side of the mounting plate 13 is adjustablely disposed with the first mounting column 15 and the second mounting column 16 via a corresponding mounting head 17. The lifting base assembly 7 is slidably connected to the guide plate 14 via a first "C"-shaped plate. The first "C"-shaped plate is fixedly connected to the movable end of the lead screw assembly 33.

[0042] To facilitate the installation of the transverse sliding rail assembly 5, a first mounting post 15 and a second mounting post 16 are provided to adjust the mounting plate 13 in the transverse sliding rail assembly 5. This adjustability means that after the transverse sliding rail assembly 5 is installed on the first mounting post 15 and the second mounting post 16, its height can be adjusted, and it can be fixed in a certain position for subsequent operation. It should be emphasized that the lead screw assembly 33 is positioned along the length of the transverse sliding rail assembly 5. The movable end of the lead screw assembly 33 is fixedly connected to the first "C"-shaped plate 35, allowing the first "C"-shaped plate 35 to slide reciprocally along the guide plate 14. The lead screw assembly 33 is a conventional lead screw assembly, sufficient only to drive the first "C"-shaped plate 35 reciprocally.

[0043] Preferably, a first horizontal plate 18 and a second horizontal plate 19 are sleeved between the first mounting post 15 and the second mounting post 16. The first horizontal plate 18 is fixedly disposed between the first mounting post 15 and the second mounting post 16, and the second horizontal plate 19 is movably disposed on the first mounting post 15 and the second mounting post 16. The mounting head 17 is fixedly disposed with the second horizontal plate 19, and a threaded rod 20 is vertically rotatably disposed on the second horizontal plate 19. The threaded rod 20 is threadedly connected to the first horizontal plate 18.

[0044] By setting the mounting head 17, the first horizontal plate 18 is movably connected to the first mounting post 15 and the second mounting post 16, and a fixed second horizontal plate 19 is set on the first mounting post 15 and the second mounting post 16. Furthermore, a threaded rod 20 is set between the first horizontal plate 18 and the second horizontal plate 19 to realize the relative drive between the first horizontal plate 18 and the second horizontal plate 19. This enables the first horizontal plate 18 to drive the entire transverse sliding rail assembly 5 to be adjusted for lifting and lowering control.

[0045] Preferably, the lifting base assembly 7 includes a vertical support plate 36 fixedly connected to the first "C"-shaped plate 35, and a lifting screw column 23 fixed on the vertical support plate 36. The lifting screw column 23 is provided with a vertical guide plate 22, and a second "C"-shaped plate 21 is sleeved on the vertical guide plate 22. A movable plate 24 is fixedly provided on the second "C"-shaped plate 21, and the second "C"-shaped plate 21 is fixedly connected to the moving end of the lifting screw column 23.

[0046] Similarly, the lifting base assembly 7 is configured to achieve lateral movement connection through the connection between the first "C"-shaped plate 35 and the lead screw assembly 33. The lifting lead screw column 23 is also configured on the lifting base assembly 7 to control the vertical movement connection of the movable plate 24, thereby enabling the movable plate 24 to be raised and lowered in the height direction, and thus enabling the cylinder gripper 8 to be raised and lowered.

[0047] Preferably, the cylinder gripper 8 is fixedly disposed at the bottom of the movable plate 24. The cylinder gripper 8 includes a double-headed cylinder 25 and grippers 26 symmetrically disposed on the double-headed cylinder 25. The two grippers 26 are connected to the movable end of the double-headed cylinder 25.

[0048] Understandably, since the cylinder gripper 8 is located at the bottom of the movable plate 24, the cylinder gripper 8 can be raised and lowered as the movable plate 24 rises and falls, thereby performing a gripping operation on the fixture 3. More specifically, the cylinder gripper 8 includes a double-headed cylinder 25, which can control the two grippers 26 in the lateral direction, thereby realizing the control of the opening and closing gripping operation.

[0049] Preferably, the flipping clamping assembly 9 includes a rotary cylinder 27 fixed on the gripper 26 and an arc-shaped gripper 28 disposed at the rotating end of the rotary cylinder 27.

[0050] In order to achieve better gripping and flipping of the jig 3, a rotary cylinder 27 is provided on the gripper 26, and an arc-shaped gripper 28 is provided at the rotating end of the rotary cylinder 27, so as to better perform the flipping operation after gripping the jig 3 and improve stability.

[0051] Preferably, the fixture 3 includes a chassis 29 and a receiving annular groove 30 disposed on the chassis 29.

[0052] During the operation of the EVA pad 34, the EVA pad 34 is placed into the receiving ring groove 30 in the fixture 3 for conveying. The path is as follows: after being conveyed by rotation, it is clamped and then conveyed in a straight line, and then flipped so that the fixture 3 is tightly fastened to the speaker to be processed. This realizes the stamping of the EVA pad 34 onto the speaker. The fixture 3, after completing the installation of the EVA pad 34, returns along the original path. Thus, multiple fixtures 3 can be set up to circulate on the path, thereby improving the processing efficiency.

[0053] Preferably, the upper surface of the workbench 1 is provided with a protective cover 31, and the rotating support platform 2 is placed inside the protective cover 31.

[0054] It is understandable that by setting a protective cover 31 on the upper surface of the workbench 1 and placing the rotating support table 2 inside the protective cover 31, the working area is protected to a certain extent, thereby improving the safety of processing.

[0055] In a preferred embodiment, a counting sensor component 32 is provided near the mounting column assembly 6. The infrared sensor component 32 is vertically positioned and located directly above the rotating support platform 2 to perform counting operations on the placed and transferred fixture 3, thereby improving the counting accuracy of processing the EVA pad sheet 34.

[0056] The working principle and process of this utility model:

[0057] The present invention provides an EVA pad installation device for speaker processing. During operation, the EVA pad 34 is placed into the receiving ring groove 30 of the fixture 3 for conveying. The path is as follows: after being conveyed by rotation, it is clamped and then conveyed in a straight line, and then flipped so that the fixture 3 is tightly fastened to the speaker to be processed. This achieves the pressing of the EVA pad 34 onto the speaker. The fixture 3, after completing the installation of the EVA pad 34, returns along the original path. Therefore, multiple fixtures 3 can be set up to circulate on the path, thereby improving the processing efficiency. More specifically, by installing a horizontally rotating support platform 2 on the set workbench 1, the rotating support platform 2 achieves horizontal rotation under the rotation control of the support platform rotation control component 4, thereby performing a rotational operation on the corresponding fixture 3, and then rotating it to the bottom of the horizontal movement slide rail component 5. By installing the cylinder gripper 8 on the lifting base component 7 that is slidably set on the horizontal movement slide rail component 5, the fixture 3 on the rotating support platform 2 is grasped and linearly transported, and under the action of the flip clamping component 9 set on the cylinder gripper 8, it rotates 180°, so that the EVA pad 34 placed on the fixture 3 flips and engages with the speaker that needs to be processed, thereby realizing the stamping and installation of the EVA pad 34.
