Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of clamp, especially relates to a clamp with soft film for bluetooth headset production. BACKGROUND

[0002] In the production process of bluetooth headset, the clamp is an indispensable tool, and its main function is to fix the headset parts to ensure the accuracy and efficiency of the production process. The traditional clamp design mostly adopts the way of directly contacting the headset parts with rigid materials to achieve fixation. The shell of the bluetooth headset is usually made of plastic or metal materials, while the internal components include more precise components such as circuit boards, speakers, etc. These materials are easily damaged by scratches, indentations, etc. under the direct clamping of the rigid clamp. These damages not only affect the appearance quality of the product, but also may adversely affect the internal performance of the headset, reducing the overall quality of the product.

[0003] In order to solve this problem, the industry has begun to try to add soft film design to the clamp. The soft film can form a buffer between the clamp and the headset parts, effectively reducing the damage risk caused by excessive clamping force. This design improves the safety of the production process to some extent and reduces the probability of product damage. However, the existing soft film material still has deficiencies in wear resistance. In the production process of bluetooth headset, the clamp is used frequently, and the friction between the soft film and the headset parts is frequent. This high-intensity friction causes the soft film to wear out easily, and once it is worn to a certain extent, its buffering protection performance will be greatly reduced, and it can no longer effectively prevent the headset parts from being scratched or damaged.

[0004] Therefore, it is necessary to design a clamp with soft film for bluetooth headset production. INVENTION CONTENTS

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Embodiment: a clamp with soft film for Bluetooth earphone production, like Figures 1-7As shown, the fixture includes a base plate 1, casters 2, mounting base 3, robotic arm 4, mounting plate 5, connecting shell 6, motor 7, clamping plate 1 8, infrared sensor 9, fixing shell 10, clamping cylinder 11, torsion spring 12, chuck wheel 13, small electric slide rail 14, clamping rod 15, mounting bracket 16, handle 17, screw 18, guide rod 19, clamping plate 20, and soft pad 21. The base plate 1 serves as the basic support structure for the entire fixture, bearing all other components. Casters 2 are installed at the four corners of the bottom of the base plate 1, allowing the fixture to move flexibly and easily transfer between different work locations. The mounting base 3 is connected to the top of the base plate 1, and the robotic arm 4 is mounted on the top of the mounting base 3. The robotic arm 4 has multi-degree-of-freedom motion capability. The robotic arm 4 is used for precise control and movement of the mounting plate 5 and its components. The gripper end of the robotic arm 4 is rotatably connected to the mounting plate 5. A connecting shell 6 is connected to the front of the mounting plate 5. Motors 7 are symmetrically installed inside the connecting shell 6. The output shafts of the motors 7 are all connected to clamping plates 8 via rotating shafts. These rotating shafts are rotatably connected to the bottom of the mounting plate 5. A soft membrane is provided on the inner side of each clamping plate 8 to directly contact and protect the Bluetooth headset from pinching. The clamping plates 8 are opened and closed by the motors 7 to hold the Bluetooth headset. An infrared sensor 9 is installed on the outer side of the gripper end of the robotic arm 4 to detect the position of the Bluetooth headset and assist the robotic arm 4 in precise positioning. A fixing shell is connected to the bottom of each clamping plate 8. 10. A clamping sleeve 11 is rotatably connected between the front and rear sides of the interior of the fixed housing 10. A soft membrane is also fitted over the outer side of the clamping sleeve 11. The front and rear ends of the clamping sleeve 11 rotatably extend through the front and rear sides of the fixed housing 10. A torsion spring 12 connects the front and rear ends of the clamping sleeve 11 to the rotation of the fixed housing 10. The torsion springs 12 are fitted around the front and rear ends of adjacent clamping sleeves 11. A locking wheel 13 is connected to the front and rear ends of the clamping sleeve 11. The locking wheel 13 is located inside the fixed housing 10. A small electric slide rail 14 is installed at the bottom of the fixed housing 10. A locking rod 15 is connected to the small electric slide rail 14 via a slider. Both ends of the locking rod 15 engage with the locking grooves on the outer side of the locking wheel 13, realizing the locking and releasing function of the clamping sleeve 11. (The last sentence appears to be incomplete and possibly refers to a different installation.) A mounting bracket 16 is connected to the front side of the mounting bracket 16. Screws 18 are symmetrically and laterally rotatably connected to the front side of the mounting bracket 16. A handle 17 is connected to the end of each screw 18 that is close to each other. Guide rods 19 are symmetrically and laterally connected to the front side of the mounting bracket 16. The guide rods 19 are all located below the adjacent screws 18. The outer ends of the screws 18 are connected to clamps 20 by threads. The handles 17 are used to manually rotate the screws 18 to adjust the position of clamps 20. Clamps 20 are slidably connected to the adjacent guide rods 19. A soft pad 21 is connected to the inner side of clamps 20 and to the outer side of the mounting bracket 16. The soft pads 21 are used to increase the friction between the contact surface and clamps 20 and play an anti-slip role.

[0024] When the clamp is needed to be used, firstly, the clamp is moved to the designated work site by the universal wheel 2. Then, the knob 17 is manually rotated to adjust the position of the second clamping plate 20 through the threaded connection. The second clamping plate 20 is smoothly slid on the guide rod 19, and after being adjusted to the appropriate position, the mounting frame 16 in the clamp and the second clamping plate 20 are fixed in the appropriate position of the work site to ensure that the clamp does not move unnecessarily during use. The soft pad 21 equipped inside the second clamping plate 20 can increase the friction between the second clamping plate 20 and the contact surface, and play a role in preventing slipping. After the second clamping plate 20 is fixed, the subsequent production operation can be started.

[0025] Next, the mechanical arm 4 is started, and the flexible multi-degree-of-freedom movement capability thereof is utilized, and the position of the Bluetooth earphone is accurately detected by the infrared ray 9, so that the mounting plate 5 and all components thereon can be accurately aligned with the Bluetooth earphone. Then, the motor 7 is started to drive the first clamping plate 8 to open and close. Since the soft film is specially arranged inside the first clamping plate 8, it can be ensured that the Bluetooth earphone will not be damaged during clamping.

[0026] When the first clamping plate 8 and the clamping cylinder 11 tightly and stably clamp the Bluetooth earphone, the mechanical arm 4 can be used to transfer the Bluetooth earphone to another production line. Then, the motor 7 is started again to slowly open the first clamping plate 8, and at the same time, the clamping cylinder 11 is also released under the action of the torsional spring 12, so that the Bluetooth earphone is safely released.

[0027] During the entire operation process, the stability and accuracy of the clamp are crucial, which can directly ensure the production quality and overall efficiency of the Bluetooth earphone. In addition, through the design of the small electric sliding rail 14 and the clamping rod 15, when the contact surface of the clamping cylinder 11 is worn, the small electric sliding rail 14 can be started to drive the clamping rod 15 to move outward, so as to release the clamping cylinder 11. At this time, the clamping cylinder 11 can be manually rotated to realize turning over, and the torsional spring 12 is deformed under the action of force. Then, the small electric sliding rail 14 is controlled again to drive the clamping rod 15 to move inward and be clamped into the clamping groove of the clamping wheel 13 at the front and rear ends of the clamping cylinder 11, so as to realize the re-fixing of the clamping cylinder 11. Through such operation, the soft film and the clamping cylinder 11 do not need to be frequently replaced, which is conducive to the clamping of the Bluetooth earphone in the subsequent process and improves the durability and economy of the clamp.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model and not to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced equivalently without departing from the essence and scope of the technical solutions of the utility model.
