Description

Technical Field

[0001] This utility model belongs to the field of mask production technology, specifically a mask ear loop spot welding reinforcement machine. Background Technology

[0002] When respiratory infectious diseases are prevalent or when working in environments polluted by dust, germs and dust in the air can enter the lungs through respiration, causing serious damage to the body. Wearing a mask can play a certain filtering role. The mask should fit tightly to the face to prevent germs and dust from easily leaking in. The mask is equipped with ear loops to fix the mask to the head.

[0003] However, in the existing technology, the connection between the ear loops and the main body of the mask is done by manual welding, which is ultrasonic welding. There is also manual stitching by manually checking the ear loop interface point by point. The long-term spot welding work will cause worker fatigue and affect the spot welding effect. This method requires a lot of labor, has low work efficiency, and inconsistent quality, which is not conducive to widespread promotion and popularization. Utility Model Content

[0004] The purpose of this utility model is to provide a mask ear loop spot welding reinforcement machine. By setting up a spot welding mechanism and a clamping mechanism, it improves the problems of manual point-by-point welding, which consumes a lot of labor, has low work efficiency, and slow production speed.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a mask ear loop spot welding reinforcement machine, comprising a base plate and a spot welding mechanism. The base plate is provided with a spot welding mechanism and a clamping mechanism. The spot welding mechanism includes two side columns fixedly connected to the base plate. A slide rail is fixedly connected to the inner wall of the two side columns. A slider is slidably connected to the outer wall of the slide rail. A motor is fixedly connected to the inner wall of the slide rail. A rotating shaft is fixedly connected to the output end of the motor via a coupling. A half gear is fixedly connected to the rotating shaft. A slider tooth groove is formed on the bottom surface of the slider. The half gear meshes with the slider tooth groove. A round rod is slidably connected to the inner wall of the slider. A spring is wound around the outer wall of the round rod. A straight groove is formed on the front side of the slider. A straight groove slider is slidably connected to the inner wall of the straight groove. A connecting rod is fixedly connected to the outer wall of the straight groove slider. A connecting column is fixedly connected to the bottom surface of the connecting rod. A limit plate is fixedly connected to the front side of the two side columns. The connecting column slides through the limit plate. A welding point plate frame is fixedly connected to the bottom end of the connecting column. A welding point pen is fixedly connected to the bottom surface of the welding point plate frame.

[0007] Furthermore, the clamping mechanism includes a base plate with several base plate feet fixedly connected to the bottom surface of the base plate, a second motor fixedly connected to the inner wall of the base plate, and a second rotating shaft fixedly connected to the output end of the second motor via a coupling.

[0008] Furthermore, a disc is fixedly connected to the outer wall of the second rotating shaft, and an eccentric shaft is fixedly connected to the top surface of the disc.

[0009] Furthermore, a hinge rod is rotatably connected to the outer wall of the eccentric shaft, and a connecting shaft is rotatably connected to the left side of the hinge rod.

[0010] Furthermore, a driving block is rotatably connected to the outer wall of the connecting shaft. The driving block has several teeth on its front and rear sides, and the sleeve has several teeth on its outer wall. The teeth are respectively engaged with the teeth.

[0011] Furthermore, a cylinder is slidably connected to the inner wall of the sleeve, the top end of the cylinder is fixedly connected to the bottom surface of the limiting plate, and a connecting block is rotatably connected to one side of the outer wall of the sleeve.

[0012] Furthermore, the bottom of the sleeve is provided with an ear loop clamp, and the bottom surface of the welding point plate frame is fixedly connected with a support column, the bottom end of the support column being fixedly connected to the top surface of the base plate.

[0013] This utility model has the following beneficial effects:

[0014] By setting up a spot welding mechanism, when the drive motor rotates slowly, it drives the rotating shaft to rotate the fixedly connected half gear. When the half gear rotates, the sliding block tooth groove that meshes with it is also driven to rotate, and the slider is driven to slide. Since there is a straight groove on the front side of the slider, the connecting rod connecting column, the welding point plate frame, and the welding point pen move downwards, thus completing the spot welding process. When the half gear rotates, the spring connected to the slider is compressed to a tight state. When the half gear rotates to the other side where there is no gear, the half gear and the slider disengage, and the slider is bounced back to the left by the spring. The connecting rod connecting column, the welding point plate frame, and the welding point pen return to the highest point, thus completing one spot welding process. The ingenuity of this design lies in its use of the advantages of mechanical transmission. Through the reciprocating motion of the half gear and the spring, the spot welding work can be completed continuously according to the predetermined motion. Through this rotation and rebound mechanism, the spot welding work can maintain a reliable state under different working conditions.

[0015] 2. By setting up a clamping mechanism, when the drive motor rotates slowly, it drives the rotating shaft to rotate the fixedly connected disc. When the disc rotates, the coupling connected to the rotating disc is driven to rotate, and the drive block connected to the rotating coupling is moved left and right. The teeth of the drive block mesh with the teeth of the two sleeves, and the two sleeves are driven to rotate in opposite directions. Since the welding point plate frame and the sleeves are fixedly connected at both ends of the connecting block, the sleeves are driven along with the up and down movement of the welding point plate frame. The ear strap clamp fixedly connected to the bottom of the outer wall of the sleeve has a cylinder that can tighten and loosen. Thus, the ear strap clamp completes a series of operations such as clamping, rotating and releasing. This design greatly improves the process of repeatedly releasing ear straps for spot welding and greatly improves work efficiency.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 As shown, this utility model is a mask ear loop spot welding reinforcement machine, including a base plate 1 on which a spot welding mechanism 2 and a clamping mechanism 3 are provided;

[0027] The spot welding mechanism 2 includes two side columns 11 fixedly connected to the base plate 1. A slide rail 25 is fixedly connected to the inner wall of the two side columns 11. A slider 24 is slidably connected to the outer wall of the slide rail 25. A motor 21 is fixedly connected to the inner wall of the slide rail 25. A rotating shaft 22 is fixedly connected to the output end of the motor 21 via a coupling. A half-gear 23 is fixedly connected to the rotating shaft 22.

A welding point plate frame 294 is fixedly connected to the bottom end of the connecting post 292. The bottom surface of the welding point plate frame 294 is fixedly connected to the bottom surface of the welding point plate frame 294. A spot welding pen 295 is fixedly connected to a welding mechanism 2. When the drive motor 21 rotates slowly, it drives the rotating shaft 22 to rotate the fixedly connected half gear 23. When the half gear 23 rotates, the slider tooth groove 297 that meshes with it is driven to rotate accordingly, and the slider 24 is driven to slide accordingly. Since the front side of the slider 24 has a straight groove 28, the connecting rod 291, connecting column 282, welding plate frame 294, and welding pen 295 move downward accordingly, thereby completing the spot welding process. When the half gear 23 rotates, the spring 27 connected to the slider 24 is compressed to a tightened state. When the half gear 27 rotates to the other side without gears, the half gear 27 disengages from the slider 24, and the slider 24 is springed back to the left by the spring. The connecting rod 291, connecting column 282, welding point plate frame 294, and welding point pen 295 return to the highest point, thus completing one spot welding procedure. The ingenuity of this design lies in its use of the advantages of mechanical transmission to make reciprocating motion between the half gear and the spring, which can continuously complete the spot welding work according to the predetermined motion. Through this rotation and rebound mechanism, it is ensured that the spot welding work can maintain a reliable state under different working conditions.

[0028] The clamping mechanism 3 includes a base plate 1 with several base plate feet 12 fixedly connected to its bottom surface. A second motor 31 is fixedly connected to the inner wall of the base plate 1. The output end of the second motor 31 is fixedly connected to a second rotating shaft 32 via a coupling. A disc 33 is fixedly connected to the outer wall of the second rotating shaft 32. An eccentric shaft 34 is fixedly connected to the top surface of the disc 33. A hinge rod 35 is rotatably connected to the outer wall of the eccentric shaft 34. A connecting shaft 36 is rotatably connected to the left side of the hinge rod 35. A driving block is rotatably connected to the outer wall of the connecting shaft 36. 37. The drive block 37 has a plurality of teeth 38 on its front and rear sides, and the sleeve 39 has a plurality of teeth 391 on its outer wall. The plurality of teeth 38 mesh with the plurality of teeth 391 respectively. A cylinder 392 is slidably connected to the inner wall of the sleeve 39. The top end of the cylinder 392 is fixedly connected to the bottom surface of the limiting plate 293. A connecting block 393 is rotatably connected to one side of the outer wall of the sleeve 39. A connecting block 393 is fixedly connected to the top surface of the sleeve 39. The left side of the connecting block 391... The sleeve 39 is fixedly connected to the right side of the welding point plate frame 294. An ear loop clamp 394 is provided at the bottom of the sleeve 39. A support column 296 is fixedly connected to the bottom surface of the welding point plate frame 294. The bottom end of the support column 296 is fixedly connected to the top surface of the base plate 1. Through the clamping mechanism 3, when the drive motor 31 rotates slowly, it drives the rotating shaft 32 to rotate the fixedly connected disc 33. When the disc 33 rotates, the coupling connected to the disc 33 is driven to rotate, and the drive block 37 connected to the coupling is moved left and right. The drive block teeth engage with the teeth of the two sleeves 39, causing the two sleeves 39 to rotate in opposite directions. Since the connecting block 393 is fixedly connected to the welding point plate 294 and the sleeves 39 at both ends, the sleeves 39 are driven along with the welding point plate 294 as it moves up and down. The ear loop clamp 394, which is fixedly connected to the bottom of the outer wall of the sleeve 39, is equipped with a cylinder that can tighten and loosen. Thus, the ear loop clamp 394 completes a series of tasks such as clamping, rotating, and releasing. This design greatly improves the process of repeatedly releasing and releasing ear loops for spot welding, and greatly improves work efficiency.

[0029] A specific application of this embodiment is as follows: By setting up a spot welding mechanism 2, when the drive motor 21 rotates slowly, it drives the rotating shaft 22 to rotate the fixedly connected half gear 23. When the half gear 23 rotates, the slider tooth groove 297 that meshes with it is driven to rotate accordingly, and the slider 24 is driven to slide accordingly. Since the front side of the slider 24 has a straight groove 28, the connecting rod 291, connecting post 282, welding plate frame 294, and welding pen 295 move downward accordingly, thereby completing the spot welding process. When the half gear 23 rotates, the spring 27 connected to the slider 24 is compressed to a tightened state. When the half gear 27 rotates to the other side where there is no gear, the half gear 24 rotates to a tightened state. Gear 27 disengages from slider 24, slider 24 is springed back to the left by spring, and connecting rod 291, connecting column 282, welding point plate frame 294, and welding point pen 295 return to the highest point, thus completing one spot welding process. The ingenuity of this design lies in its use of the advantages of mechanical transmission to make reciprocating motion between half gear and spring, which can assist workers to continuously complete spot welding work according to the machine's predetermined motion, ensuring the consistency and stability of welding quality, and improving the problems of slow spot welding production speed and low production efficiency. Through this rotation and rebound mechanism, it is ensured that spot welding work can maintain a reliable state under different working conditions.

[0030] With the clamping mechanism 3 in place, the drive motor 31 rotates slowly, driving the rotating shaft 32 to rotate the fixedly connected disc 33. When the disc 33 rotates, the coupling connected to the disc 33 is driven to rotate, and the drive block 37 connected to the coupling is moved left and right. The teeth of the drive block mesh with the teeth of the two sleeves 39, and the two sleeves 39 are driven to rotate in opposite directions. Since the welding point plate frame 294 and the sleeves 39 are fixedly connected at both ends of the connecting block 393, the sleeves 39 are driven along with the up and down movement of the welding point plate frame 294. The ear strap clamp 394 fixedly connected to the bottom of the outer wall of the sleeve 39 has a cylinder that can tighten and loosen. Thus, the ear strap clamp 394 completes a series of operations such as clamping, rotating and releasing. This design greatly improves the process of repeatedly releasing ear straps for spot welding and greatly improves work efficiency.
