Description

Technical Field

[0001] This utility model relates to the technical field of ear shell processing equipment, specifically an ear shell glue-applying machine. Background Technology

[0002] The ear shell targeted by this utility model is specifically the core component in the headphone manufacturing process—the ear shell made of plastic or metal. After injection molding, assembly and other processes, the surface of this type of ear shell is prone to residual stains such as injection molding excess glue, fingerprints or dust, which need to be wiped before it can enter the subsequent assembly stage.

[0003] The existing ear shell glue application machine still has the following problems in use:

[0004] Most of them adopt a single-station operation mode, which means that only one ear shell can be wiped at a time. After wiping, they have to wait for transfer and material loading and unloading before they can start the next operation. The overall wiping efficiency is low and it is difficult to meet the production capacity requirements of mass production of ear shells.

[0005] The lateral position adjustment of the adhesive wiping component is not flexible enough to adapt to the wiping needs of ear shells of different sizes and specifications. Furthermore, the tension of the lint-free cloth during the wiping process lacks precise control, which can easily lead to the lint-free cloth being too loose or too tight. This results in uneven wiping of the ear shell surface and residual stains in some areas. At the same time, the clamping structure during ear shell transfer lacks protective design, which can easily cause the ear shell to fall off due to slippage or damage to the ear shell surface due to excessive clamping force, thus affecting the product yield. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides an ear shell glue application machine. By setting up a dual-station feeding transmission component, an adjustable horizontal adjustment component, and an ear shell transfer component with a protective structure, it solves the problems of low single-station efficiency, poor adaptability of glue application components, and easy damage to ear shells during handling in existing ear shell glue application machines.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: an ear shell glue application machine, comprising a bottom-mounted ear shell assembly assembly, a horizontal adjustment assembly, and two sets of symmetrically arranged glue application assemblies.

[0010] The ear shell adhesive application machine also includes a frame assembly, a feeding and transmission assembly, and an ear shell transfer assembly; wherein, the bottom-mounted ear shell assembly assembly is fixed to the bottom of the frame assembly to provide stable support for the entire equipment, prevent the position of each component from shifting due to vibration during equipment operation, and ensure wiping accuracy.

[0011] The frame assembly includes a base plate and a vertical frame. The vertical frame is vertically fixed to the rear end of the upper surface of the base plate. The base plate is made of high-strength aluminum alloy, which combines lightweight and rigidity and can bear the weight of the feeding transmission assembly and the ear shell transfer assembly. The vertical frame provides an installation reference for the horizontal adjustment assembly and the ear shell transfer assembly, ensuring the coaxiality and verticality of each assembly.

[0012] The horizontal adjustment assembly includes an X2-axis linear drive mechanism fixedly installed at the front end of the stand. The X2-axis linear drive mechanism is arranged parallel to the X1-axis linear drive mechanism, and the moving end of the X2-axis linear drive mechanism has two fixed moving seats. The X2-axis linear drive mechanism adopts servo drive control, which can realize precise lateral displacement of the moving seats, thereby driving the adhesive wiping assembly to adjust the relative distance with the wiping position, adapting to the wiping needs of ear shells of different lengths, and the adjustment accuracy can reach ±0.05mm.

[0013] Each set of adhesive wiping components corresponds to one wiping position and includes a connecting seat, a mounting bracket, a Z-axis linear drive mechanism, a Z-axis take-up motor, a Z-axis slide assembly, Z-axis fingers, a feeding cylinder, a take-up cylinder, and a wiping strip. The connecting seat is fixed to the front end of the movable seat, the Z-axis linear drive mechanism is fixedly connected to the front end of the connecting seat, the mounting bracket is fixedly installed on the front side of the moving end of the Z-axis linear drive mechanism, the Z-axis slide assembly is assembled on both sides of the middle front end of the mounting bracket, the moving end of the Z-axis slide assembly is equipped with a guide wheel assembly, the Z-axis fingers are assembled on both sides below the front end of the mounting bracket, the feeding cylinder and the take-up cylinder are respectively installed on both sides above the front end of the mounting bracket, and the wiping strip is wound around the feeding cylinder, the take-up cylinder, the Z-axis fingers, and the guide wheel assembly. The connecting seat is connected by bolts for easy disassembly and maintenance of the adhesive wiping components. The guide wheel assembly is made of polytetrafluoroethylene, which can reduce friction loss during the transmission of the wiping strip and extend the service life of the cleanroom cloth. The Z-axis fingers are pneumatic gripper structures that can quickly clamp the wiping strip and prevent the cleanroom cloth from shifting during wiping.

[0014] As a further improvement of this utility model: the feeding transmission assembly includes a Y-axis A linear drive mechanism and a Y-axis B linear drive mechanism fixed parallel to the base plate. The moving end of the Y-axis A linear drive mechanism is provided with an A1 feeding position, an A2 wiping position, and an A3 picking position in sequence along its movement direction. The moving end of the Y-axis B linear drive mechanism is provided with a B1 feeding position, a B2 wiping position, and a B3 picking position in sequence along its movement direction. The Y-axis A linear drive mechanism and the Y-axis B linear drive mechanism operate synchronously and independently, which can realize parallel wiping operations at two stations. Compared with a single-station device, the efficiency is increased by more than 1 times. Moreover, each station is provided with a positioning pin to ensure the positional accuracy of the ear shell during the feeding, wiping, and picking processes.

[0015] As a further improvement of this utility model: the ear shell transfer assembly includes an X1-axis linear drive mechanism, an X1-axis lifting mechanism, and an X1-axis pneumatic finger. The X1-axis linear drive mechanism is fixed to the rear side of the top of the base plate, the X1-axis lifting mechanism is fixed to the moving end of the X1-axis linear drive mechanism, and the X1-axis pneumatic finger is fixed to the telescopic end of the X1-axis lifting mechanism. The movement speed of the X1-axis linear drive mechanism can be adjusted by the control system to adapt to the ear shell transfer requirements of different weights. The telescopic stroke of the X1-axis lifting mechanism is 30-50mm, which can quickly complete the lifting and transfer of the ear shell and reduce waiting time.

[0016] As a further embodiment of this invention: the ear shell transfer assembly further includes a first YA-axis rotary drive mechanism fixedly mounted on the moving end of the Y-axis A linear drive mechanism, a second YA-axis rotary drive mechanism fixedly mounted on the rotating end of the first YA-axis rotary drive mechanism, and an ear shell placement seat fixedly mounted on the rotating end of the second YA-axis rotary drive mechanism. The ear shell transfer assembly also includes a first YB-axis rotary drive mechanism fixedly mounted on the moving end of the Y-axis B linear drive mechanism, a second YB-axis rotary drive mechanism fixedly mounted on the rotating end of the first YB-axis rotary drive mechanism, and an ear shell placement seat fixedly mounted on the rotating end of the second YB-axis rotary drive mechanism. Both sets of rotary drive mechanisms adopt a 360° adjustable design. The first servo motor is responsible for switching the horizontal / vertical posture of the ear shell, and the second servo motor is responsible for fine-tuning the angle of the ear shell, which can make the surface of the ear shell completely fit with the wiping strip and avoid wiping dead corners.

[0017] As a further improvement of this utility model: the Z-axis take-up motor is connected to the take-up cylinder via a drive connection, and the output shaft of the Z-axis take-up motor is connected to the rotating shaft of the take-up cylinder via a coupling; the Z-axis take-up motor can adjust the tension of the wiping strip through torque control, and the tension range can be set to 5-15N, which can ensure that the lint-free cloth does not loosen during wiping, and also avoid the lint-free cloth from breaking due to excessive tightness.

[0018] As a further improvement of this utility model: the X1 axis pneumatic finger is a parallel gripper structure, and a flexible rubber pad with a thickness of 1-2mm is fixedly attached to the inner side of the gripper; the surface of the rubber pad is provided with fine anti-slip texture, which can prevent the ear shell from slipping and falling off when gripping the ear shell, and at the same time prevent the gripper from causing pressure damage to the surface of the ear shell; the flexible rubber pad is made of food-grade silicone material, which is odorless and wear-resistant, and will not leave marks on the surface of the ear shell, ensuring the appearance quality of the product.

[0019] As a further improvement of this utility model: a dispensing valve is fixedly installed at the lower center of the front end of the mounting bracket, which can spray adhesive remover (specifically, alcohol, white spirit, or other cleaning agents); the amount of adhesive remover sprayed by the dispensing valve can be precisely adjusted by the control system, with a single spray amount of 0.1-0.5mL. After the alcohol adhesive remover is sprayed onto the wiping strip, when the wiping strip with adhesive remover is used to wipe the adhesive stains on the surface of the ear shell, it can quickly dissolve the adhesive stains and improve the cleaning effect.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. In this utility model, a dual-station feeding structure is formed by setting up dual linear drive mechanisms on Y-axis A and Y-axis B. With the help of the X1 axis ear shell transfer component, the ear shell can be quickly transferred between the two stations. At the same time, the two sets of adhesive wiping components work synchronously. Compared with the traditional single-station equipment, the wiping efficiency is effectively increased by more than 100%, which can meet the production capacity requirements of mass production of ear shells. Moreover, the X2 axis linear drive mechanism can adjust the lateral position of the adhesive wiping component to adapt to ear shells of different sizes from 20-50mm, making it more versatile.

[0022] 2. In this utility model, the adhesive wiping assembly uses a Z-axis take-up motor to rotate the take-up cylinder and, in conjunction with the Z-axis slide assembly to adjust the guide wheel assembly, can precisely control the tension of the wiping strip, avoiding situations where the cloth surface is loose or too tight during wiping. At the same time, the adhesive dispensing valve precisely sprays adhesive remover, which can help the wiping strip dissolve adhesive residue, ensuring that the ear shell surface is wiped evenly without residue. In addition, the flexible rubber pad and anti-slip texture design of the X1 axis pneumatic fingers can reduce the ear shell gripping slippage rate and crushing rate to below 0.5%, significantly improving the product yield.

All of these use commercially available bus absolute value servo systems, and the dispensing valve is a pneumatic precision dispensing valve. The control logic of the above components is implemented through PLC programming, which is a conventional technical means in this field and will not be described in detail here.

[0032] Please see Figures 1-4 In this embodiment of the utility model, an ear shell adhesive application machine includes a bottom-mounted ear shell assembly 1, a horizontal adjustment assembly 2, and two sets of symmetrically arranged adhesive application assemblies 3.

[0033] The ear shell adhesive application machine also includes a frame assembly, a feeding and transmission assembly, and an ear shell transfer assembly; among them, the bottom-mounted ear shell assembly 1 is fixed to the bottom of the frame assembly to provide stable support for the entire equipment, prevent the position of each component from shifting due to vibration during equipment operation, and ensure wiping accuracy.

[0034] The frame assembly includes a base plate 11 and a vertical frame 114. The vertical frame 114 is vertically fixed to the rear end of the upper surface of the base plate 11. The base plate 11 is made of high-strength aluminum alloy, which combines lightweight and rigidity and can bear the weight of the feeding transmission assembly and the ear shell transfer assembly. The vertical frame 114 provides an installation reference for the horizontal adjustment assembly 2 and the ear shell transfer assembly, ensuring the coaxiality and verticality of each assembly.

[0035] The horizontal adjustment component 2 includes an X2-axis linear drive mechanism 21 fixedly installed at the front end of the stand 114. The X2-axis linear drive mechanism 21 is arranged parallel to the X1-axis linear drive mechanism 115, and the moving end of the X2-axis linear drive mechanism 21 is fixed with two moving seats 22. The X2-axis linear drive mechanism 21 adopts servo drive control, which can realize the precise lateral displacement of the moving seats 22, thereby driving the adhesive wiping component 3 to adjust the relative distance with the wiping position, adapting to the wiping needs of ear shells of different lengths, and the adjustment accuracy can reach ±0.05mm.

[0036] Each set of adhesive wiping components 3 corresponds to one wiping position and includes a connecting seat 31, a mounting bracket 32, a Z-axis linear drive mechanism 33, a Z-axis take-up motor 34, a Z-axis slide assembly 35, a Z-axis finger 36, a feeding cylinder 37, a receiving cylinder 38, and a wiping strip 39 (which can be a dust-free cloth strip). The connecting seat 31 is fixed to the front end of the movable seat 22, the Z-axis linear drive mechanism 33 is fixedly connected to the front end of the connecting seat 31, the mounting bracket 32 ​​is fixedly installed on the front side of the moving end of the Z-axis linear drive mechanism 33, and the Z-axis slide assembly 35 is assembled on both sides of the middle front end of the mounting bracket 32.

The assembly includes a guide wheel assembly, with Z-axis fingers 36 mounted on both sides below the front end of the mounting bracket 32. A feeding cylinder 37 and a receiving cylinder 38 are respectively mounted on both sides above the front end of the mounting bracket 32. A wiping strip 39 is wound around the feeding cylinder 37, the receiving cylinder 38, the Z-axis fingers 36, and the guide wheel assembly. The connecting seat 31 is detachably connected with bolts, facilitating the disassembly and maintenance of the wiping assembly 3. The guide wheel assembly is made of polytetrafluoroethylene (PTFE), which reduces frictional loss during the transmission of the wiping strip 39 and extends the service life of the cleanroom cloth. The Z-axis fingers 36 are pneumatic grippers that can quickly clamp the wiping strip 39, preventing the cleanroom cloth from shifting during wiping.

[0037] The feeding transmission assembly includes a Y-axis A linear drive mechanism 12 and a Y-axis B linear drive mechanism 13, which are fixed parallel to the base plate 11. The moving end of the Y-axis A linear drive mechanism 12 is provided with an A1 feeding position 14, an A2 wiping position 16, and an A3 picking position 18 in sequence along its movement direction. The moving end of the Y-axis B linear drive mechanism 13 is provided with a B1 feeding position 15, a B2 wiping position 17, and a B3 picking position 19 in sequence along its movement direction. The Y-axis A linear drive mechanism 12 and the Y-axis B linear drive mechanism 13 operate synchronously and independently, which can realize parallel wiping operations at two stations. Compared with a single-station equipment, the efficiency is increased by more than 1 times. Each station is equipped with a positioning pin to ensure the positional accuracy of the ear shell during the feeding, wiping, and picking processes.

[0038] The ear shell transfer assembly includes an X1-axis linear drive mechanism 115, an X1-axis lifting mechanism 116, and an X1-axis pneumatic finger 117. The X1-axis linear drive mechanism 115 is fixed to the rear top of the base plate 11, the X1-axis lifting mechanism 116 is fixed to the moving end of the X1-axis linear drive mechanism 115, and the X1-axis pneumatic finger 117 is fixed to the telescopic end of the X1-axis lifting mechanism 116.

The output shaft of the Z-axis take-up motor 34 is connected to the rotating shaft of the take-up cylinder 38 via a coupling. The Z-axis take-up motor 34 can adjust the tension of the wiping strip 39 by torque control. The tension range can be set to 5-15N, which can ensure that the cleanroom cloth does not loosen during wiping and avoid the cleanroom cloth from breaking due to excessive tightness.

[0041] The X1 axis air finger 117 has a parallel gripper structure, with a flexible rubber pad of 1-2mm thickness fixedly attached to the inner side of the gripper. The surface of the rubber pad has fine anti-slip texture to prevent the ear shell from slipping and falling off when gripping it, and to prevent the gripper from causing pressure damage to the ear shell surface. The flexible rubber pad is made of food-grade silicone, which is odorless and wear-resistant, and will not leave marks on the ear shell surface, ensuring the product's appearance quality.

[0042] A dispensing valve is fixedly installed at the lower center of the front end of the mounting bracket 32. It can spray adhesive remover (specifically alcohol, white spirit, or other cleaning agents). The amount of adhesive remover sprayed by the dispensing valve can be precisely adjusted by the control system. The amount sprayed at one time is 0.1-0.5mL. After the alcohol adhesive remover is sprayed onto the wiping strip, the wiping strip with adhesive remover can quickly dissolve the adhesive stains on the surface of the ear shell when wiping them, which can improve the cleaning effect.
