Description

Technical Field

[0001] This utility model relates to the field of horn manufacturing technology, specifically to a glue-applying device for automobile horn production. Background Technology

[0002] Some speaker waterproofing systems are designed to be waterproof from the start, meaning the speaker itself is waterproof and can be secured with silicone rings or waterproof sealant. Other systems involve speakers that are not inherently waterproof; in these cases, a waterproof membrane needs to be applied to the appropriate locations on the speaker housing before installation. After installation, waterproof sealant is used to seal the edges to prevent water from entering the electronic device. The primary purpose of a speaker waterproof membrane is to maintain sound transmission while ensuring waterproofing. The membrane also helps to keep dust and other particles out of the waterproof and sound-permeable material.

[0003] Currently, most adhesive application for speaker brackets in the dispensing industry is done manually. This method has drawbacks such as non-standard dispensing shape, inaccurate control of adhesive amount, difficulty in controlling the dispensing position, slow speed, and low efficiency. In addition, when inspection is required, it is necessary to shut down the machine multiple times for inspection, which is time-consuming, laborious, and impractical.

[0004] To address the aforementioned problems, existing technologies provide a solution. For example, patent publication number CN218531533U discloses an automotive horn glue applicator, comprising a machine body. A placement platform and a gantry frame are fixedly installed on the top of the machine body. A glue quantity control tank is fixedly installed on one side of the gantry frame, and a glue dispensing head is fixedly installed on the gantry frame. A common hose connects the glue quantity control tank and the glue dispensing head. The placement platform includes a placement plate, on which two clamping blocks and a clamping mechanism are fixedly installed. The clamping mechanism includes a rectangular block fixedly connected to the machine body. Two rectangular rods are slidably installed on the rectangular block, and a common clamping arm is fixedly installed on the end of the two rectangular rods near the clamping block. This invention can uniformly control the amount of glue dispensed, and by making the speaker rotate at a constant speed, the glue can be evenly adhered to the speaker, resulting in a standard shape of glue applied to the speaker. It also improves the glue application efficiency of the speaker. Although existing devices can quickly apply glue to the speaker, the speaker is in a rotating state during the glue application process, and the glue gun exerts a certain force on the speaker when applying glue, which can easily cause the speaker to deflect, thus affecting the glue application effect.

[0005] To address this, a glue-applying device for automobile horn production is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a glue-applying device for automobile horn production, thereby solving the above-mentioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A glue-applying device for automobile horn production includes a base, a bracket, and a glue gun.

The servo motor is connected to the base, the drive mechanism is connected to the servo motor, the support plate is connected to the drive mechanism, the arc rack is connected to the bracket, the connecting mechanism is connected to the arc rack, and the clamping plate is connected to the connecting mechanism. When the servo motor starts, the drive mechanism controls the support plate to rotate intermittently. When the support plate rotates, the arc rack controls the connecting mechanism to operate and controls the horn clamped by the clamping plate to rotate 360 ​​degrees.

[0009] Preferably, the driving mechanism includes a reciprocating screw, a threaded block, a support frame, a transmission belt, a rotating shaft, a drive gear, and a gear ring. The reciprocating screw is connected to the support frame, the threaded block is connected to the reciprocating screw, the support frame is connected to the threaded block, the glue gun is connected to the support frame, the transmission belt is connected to the reciprocating screw, the rotating shaft is connected to the transmission belt, the drive gear is connected to the rotating shaft, the gear ring engages with the drive gear, and the support plate is connected to the drive gear.

[0010] Preferably, the drive gear includes a straight portion and a toothed portion, wherein the curvature ratio of the straight portion to the toothed portion is 1:1.

[0011] Preferably, the connecting mechanism includes a connecting gear, a reciprocating lead screw, a disc, and a mounting block. The connecting gear is connected to an arc rack, the reciprocating lead screw is connected to the connecting gear, the disc and the mounting block are both connected to the reciprocating lead screw, and the clamping plate is connected to the mounting block.

[0012] Preferably, the arc length of the rack is consistent with the circumference of the connecting gear, and the height of the rack is consistent with the height of the drive gear.

[0013] Preferably, the number of disks is 4-10, and the specific number of disks is an even number.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The support plate drives the disc to rotate, and controls the horn to rotate towards the glue gun. During the rotation of the horn, the horn is gradually clamped and released, which ensures that the horn is coated with glue in a stable state. This avoids the horn from loosening due to the centrifugal force of rotation and the pressure of the glue gun, and improves the quality of glue coating on the horn. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the embodiments described below are only some embodiments of the present utility model, and not all of them. If other embodiments are obtained by those skilled in the art without creative effort, they shall fall within the protection scope of the present utility model.

[0023] Reference Figures 1 to 5 A glue-applying device for automobile horn production includes a base 1, a bracket 2, and a glue gun 3. It also includes a servo motor 4, a drive mechanism 5, a support plate 6, an arc rack 7, a connecting mechanism 8, and a clamping plate 9. The servo motor 4 is connected to the base 1, the drive mechanism 5 is connected to the servo motor 4, the support plate 6 is connected to the drive mechanism 5, the arc rack 7 is connected to the bracket 2, the connecting mechanism 8 is connected to the arc rack 7, and the clamping plate 9 is connected to the connecting mechanism 8. When the servo motor 4 starts, the drive mechanism 5 controls the support plate 6 to rotate intermittently. When the support plate 6 rotates, the arc rack 7 controls the connecting mechanism 8 to operate and controls the horn clamped by the clamping plate 9 to rotate 360 ​​degrees.

[0024] As one embodiment of this utility model, refer to Figures 3 to 5The drive mechanism 5 includes a reciprocating screw 51, a threaded block 52, a support frame 53, a transmission belt 54, a rotating shaft 55, a drive gear 56, and a gear ring 57. The reciprocating screw 51 is connected to the bracket 2, the threaded block 52 is connected to the reciprocating screw 51, the support frame 53 is connected to the threaded block 52, the glue gun 3 is connected to the support frame 53, the transmission belt 54 is connected to the reciprocating screw 51, the rotating shaft 55 is connected to the transmission belt 54, the drive gear 56 is connected to the rotating shaft 55, the gear ring 57 is engaged with the drive gear 56, and the support plate 6 is connected to the drive gear 56. The drive gear 56 includes a straight part 561 and a toothed part 562. The curvature ratio of the straight part 561 to the toothed part 562 is 1:1. Through the above settings, the support plate 6 can be prevented from rotating continuously. By controlling the intermittent rotation of the support plate 6, the speaker can be kept still for a certain period of time, and glue can be applied to the speaker without stopping the movement of the glue gun 3.

[0025] As one embodiment of this utility model, refer to Figure 5 The connecting mechanism 8 includes a connecting gear 81, a reciprocating lead screw 82, a disc 83, and a mounting block 84. The connecting gear 81 is connected to the arc rack 7, the reciprocating lead screw is connected to the connecting gear 81, the disc 83 and the mounting block 84 are both connected to the reciprocating lead screw 82, and the clamping plate 9 is connected to the mounting block 84. The arc length of the arc rack 7 is the same as the circumference of the connecting gear 81, and the center line of the arc rack 7 is parallel to the center line of the bracket 2. Through the above settings, the direction of the horn clamping or releasing can be controlled. The rotation angle of the reciprocating screw 82 remains consistent, thereby enabling the clamping plate 9 to be reset. The height of the arc rack 7 is consistent with the height of the drive gear 56. Through the above settings, the arc rack 7 and the connecting gear 81 can be fully engaged, ensuring the stable operation of the device. The number of discs 83 is 4-10, and the specific number of discs 83 is even. Through the above settings, the discs 83 can be evenly distributed, thereby keeping the support plate 6 balanced and preventing the support plate 6 from tilting.

[0026] Working principle: In use, the user places the horn to be glued onto the disc 83 in sequence, and then starts the servo motor 4. The servo motor 4 drives the reciprocating screw 51 to rotate. When the reciprocating screw 51 rotates, it drives the support frame 53 to descend synchronously through the threaded block 52. When the support frame 53 descends, it drives the glue gun 3 to descend synchronously. At the same time, it drives the rotating shaft 55 to rotate through the transmission belt 54. When the rotating shaft 55 rotates, it drives the drive gear 56 to rotate. When the drive gear 56 rotates, it meshes with the gear ring 57 through the straight part 561, thereby driving the support plate 6 to rotate. When the support plate 6 rotates, it drives the horn to rotate towards the glue gun 3 through the disc 83. When the disc 83 carries... As the horn gradually rotates toward the glue gun 3, the connecting gear 81 engages with the arc rack 7. As the support plate 6 rotates, the connecting gear 81 rotates, driving the reciprocating screw 82 to rotate. When the reciprocating screw 82 rotates, it can drive the clamping block to move in opposite directions through the mounting block 84, thereby clamping the horn. Once the horn is clamped, the glue gun 3 descends to the position where glue needs to be applied. Then, the glue gun 3 is controlled to rotate around the horn, achieving all-round glue application to the horn. After the glue application is completed, the support plate 6 drives the horn to continue rotating. At this time, the connecting gear 81 and the arc rack 7 continue to engage. The mounting block 84 then drives the clamping block to move in the opposite direction, thereby releasing the horn and making it easier to remove.
