[0002] A hair dryer is a common household appliance with a drying function, which is often used to dry and style hair. Generally speaking, a hair dryer includes two main components: a fan assembly and a heating assembly. The operation mode is that the fan assembly draws air into the hair dryer body, and the inhaled air is heated by the heating assembly, so that the cold air becomes hot air and flows out from the hair dryer outlet to achieve the purpose of drying. The performance and quality of the heating wire, one of the core components, directly affects the use effect and safety of the hair dryer.

[0003] The traditional hair dryer heating wire welding process often relies on manual operation, which has many defects. First, the accuracy and stability of manual welding are difficult to guarantee, and problems such as uneven welding and cold welding are prone to occur, which affects the heating efficiency and service life of the heating wire. For example, in some manually welded hair dryers, due to loose welding, the heating wire may fall off or break after a period of use, causing the hair dryer to fail to work properly. Secondly, manual welding is inefficient and difficult to meet the needs of large-scale production. During the peak production season, the speed of manual welding is far behind market demand, resulting in insufficient product supply. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 8 As shown, the high-speed negative ion hair dryer heating wire assembly welding device of the present invention comprises a workbench 1, a conveyor belt 12 is installed on the workbench 1, a fixing frame 2 is evenly installed on the conveyor belt 12, a cylinder 3 is installed on the workbench 1, a pressing plate 31 is installed on the cylinder 3, the fixing frame 2 and the cylinder 3 cooperate with each other to clamp and fix the workpiece 5 to be welded, and a welding manipulator 11 is also installed on the workbench 1, and the welding manipulator 11 welds the workpiece 5;

[0035] The fixing frame 2 includes a mounting seat 21 and a lifting seat 22, wherein the mounting seat 21 is fixedly mounted on the conveyor belt 12, and the lifting seat 22 is hingedly connected to one end of the mounting seat 21 close to the welding manipulator 11, and there is a magnetic attraction between the lifting seat 22 and the mounting seat 21, and a lifting slot 221 is provided on the end of the lifting seat 22 away from the welding manipulator 11, and a lifting block 26 is installed on the workbench 1, and the lifting block 26 is trapezoidal, and the lifting block 26 and the lifting slot 221 match each other, and the lifting block 26 lifts the lifting seat 22, and the positions of the lifting block 26 and the welding manipulator 11 correspond to each other;

[0036] The lifting seat 22 is provided with a placement groove 23, and one end of the placement groove 23 away from the welding robot 11 passes through the lifting seat 22, and the surface of the placement groove 23 is smooth;

[0037] The heating wire wound on the mica sheet is placed in the placement slot 23 manually or by a robot. Then, the motor of the conveyor belt 12 is started by the controller, so that the conveyor belt 12 drives the heating wire workpiece 5 to move toward the welding robot 11. Then, when the heating wire reaches the position of the welding robot 11, the cylinder 3 drives the pressing plate 31 to extend, so that the pressing plate 31 clamps and fixes the workpiece 5 in the placement slot 23 to ensure the accurate position of the workpiece 5, thereby facilitating the welding robot 11 to weld the workpiece 5. Then, after the welding of the workpiece 5 is completed, the welding robot 11 and the cylinder 3 return to their original positions, and the conveyor belt 12 drives the heating wire to leave and unload the workpiece 5.

[0038] At the same time, in the process of placing the workpiece 5, due to the influence of vibration, mechanical error or human error, there will be an error in the position of the workpiece 5 in the placement groove 23, that is, there will be a relatively large distance between the end of the workpiece 5 close to the welding robot 11 and the side wall of the placement groove 23, and when the cylinder 3 drives the pressure plate 31 to clamp the workpiece 5, the movement speed of the cylinder 3 is relatively fast. If there is a large distance between the workpiece 5 and the side wall of the placement groove 23, the workpiece 5 is easily pushed by the pressure plate 31 and hits the side wall of the placement groove 23 relatively quickly, which causes the workpiece 5 to burst out of the placement groove 23, the workpiece 5 to collide and be damaged, or the heating wire on the workpiece 5 wound on the mica sheet skeleton is subjected to large vibration, resulting in deformation and falling off of the heating wire, affecting the subsequent smooth welding of the workpiece 5 and the quality of the workpiece 5 after welding;

[0039] Therefore, by setting the lifting block 26, when the fixing frame 2 is driven by the conveyor belt 12 to pass through the position of the lifting block 26, the lifting block 26 passes through the lifting slide groove 221, and then the lifting block 26 lifts and raises the lifting seat 22, so that the lifting seat 22 is tilted, and the placement groove 23 is tilted toward the welding robot 11, so that the workpiece 5 slides in the placement groove 23 by itself, and the workpiece 5 is close to or contacts the side wall of the placement groove 23, so that when the cylinder 3 drives the pressing plate 31 to clamp and fix the workpiece 5, the relative displacement of the workpiece 5 in the slide groove is small, thereby preventing the workpiece 5 from being damaged or squeezed out of the placement groove 23, ensuring the fixing effect of the workpiece 5 and the subsequent welding effect are good;

[0040] At the same time, in order to ensure a relatively high welding efficiency, the conveyor belt 12 drives the fixing frame 2 to move between different workstations at a relatively high speed. In this case, if the height of the jacking block 26 is relatively large and the inclination angle of the lifting seat 22 and the placement slot 23 is too large, it is easy for the lifting slide slot to collide with the jacking block 26, causing the lifting seat 22 to vibrate greatly during the jacking process, affecting the stability of the heating wire on the workpiece 5 or causing damage to the hinged connection between the lifting seat 22 and the mounting seat 21, affecting the subsequent fixation of the workpiece 5 and the welding effect. At the same time, when the height of the jacking block 26 is relatively large, it may also cause the lifting seat 22 to be lifted too fast, thereby causing the workpiece 5 in the placement slot 23 to be thrown out, affecting the stability of the workpiece 5 in the placement slot 23 and the subsequent fixation effect of the workpiece 5.

[0041] Therefore, the inner wall surface of the placement groove 23 is smoothed, so that when the lifting seat 22 is lifted up by the lifting block 26, the friction between the workpiece 5 and the inner wall of the placement groove 23 is relatively small, which is convenient for the workpiece 5 to slide and get close to the side wall of the placement groove 23, avoiding a large distance between the workpiece 5 and the side wall of the placement groove 23. At the same time, since the edge of the mica sheet skeleton is relatively rough, the inner wall surface of the placement groove 23 is smoothed, which can also avoid the edge of the mica sheet skeleton and the inner wall of the placement groove 23 from being hooked or stuck, ensuring that the workpiece 5 can easily slide and get close to the side wall of the placement groove 23 close to the end of the welding robot 11;

[0042] At the same time, the thickness of one end of the lifting block 26 facing the welding manipulator 11 is smaller than that of the other end, so that the upper surface of the lifting block 26 is an inclined surface, so that the upper surface of the lifting block 26 and the lifting slide groove 221 can match each other, ensuring that the lifting seat 22 is relatively stable during the lifting process, avoiding affecting the position of the workpiece 5 in the placement groove 23;

[0043] At the same time, on the assembly welding device, along the movement direction of the conveyor belt 12, there are, in sequence, an area where the workpiece 5 is placed, an area where the lifting seat 22 is lifted by the lifting block 26, an area where the workpiece 5 is clamped and welded by the pressing plate 31, and an area where the welded workpiece 5 is unloaded. At the same time, the various areas will not overlap with each other.

[0044] As an embodiment of the present invention, a positioning piece 25 is installed on the side wall of the placement groove 23 close to the welding robot 11, and the positioning piece 25 is symmetrically arranged. The positioning piece 25 is elastic, and the end of the positioning piece 25 away from the welding robot 11 is inserted into the notch on the workpiece 5;

[0045] After the conveyor belt 12 drives the workpiece 5 to the position of the welding robot 11, the conveyor belt 12 temporarily stops moving. Then, the cylinder 3 drives the pressure plate 31 to squeeze the workpiece 5, so that the end of the workpiece 5 close to the welding robot 11 is close to the side wall of the placement groove 23. At this time, the positioning piece 25 in the placement groove 23 will be inserted into the gap between the mica sheets on the workpiece 5, so that the positioning piece 25 simultaneously squeezes the mica sheets on both sides of the gap, so that the gap and the positioning piece 25 are aligned with each other, so that the angle of the workpiece 5 is corrected and fixed by using the symmetrically arranged and elastic positioning pieces 25, so as to ensure that the position and angle of the workpiece 5 in the placement groove 23 are accurate, so that the position of the joint to be welded on the workpiece 5 is relatively fixed, so that it is convenient for the welding robot 11 to weld the workpiece 5 and improve the quality and speed of the heating wire group welding.

[0046] As an embodiment of the present invention, the positioning piece 25 has an arc shape, and a protruding line 251 is provided on the surface of the positioning piece 25 contacting the workpiece 5;

[0047] Since the diameter of the protruding line 251 is relatively small and the positioning piece 25 is arc-shaped, when the workpiece 5 is squeezed and fixed by the pressing plate 31 and the positioning piece 25 is inserted into the notch on the workpiece 5, the positioning piece 25 is in line contact or point contact with the mica sheets on both sides of the notch on the workpiece 5 through the action of the protruding line 251 on the surface, thereby reducing the friction between the positioning piece 25 and the workpiece 5, and facilitating the positioning piece 25 to be inserted into the notch on the workpiece 5 when the pressing plate 31 squeezes and fixes the workpiece 5.

[0048] At the same time, after the welding of the workpiece 5 is completed and the clamping plate 31 releases the clamping fixation of the workpiece 5, the workpiece 5 can be easily pushed in a direction away from the welding manipulator 11 under the elastic action of the positioning piece 25, so that the workpiece 5 can be automatically separated from the positioning of the positioning piece 25, thereby facilitating the grabbing and moving of the workpiece 5 during subsequent unloading;

[0049] At the same time, since the positioning piece 25 is arc-shaped and elastic, when the pressure plate 31 clamps the workpiece 5, the workpiece 5 will first contact the positioning piece 25, and the positioning piece 25 will buffer the contact between the workpiece 5 and the inner wall of the placement groove 23, thereby preventing the workpiece 5 from colliding with the inner wall of the placement groove 23 under the extrusion of the pressure plate 31, causing damage to the mica sheet or heating wire on the workpiece 5, affecting the quality and normal use of the workpiece 5.

[0050] As an embodiment of the present invention, a blocking sheet 24 is installed on the side wall of the placement slot 23 close to the end of the welding robot 11, and the blocking sheet 24 is arranged to be tilted downward, and the blocking sheet 24 has good elasticity;

[0051] Since a blocking piece 24 is installed on the inner wall of the placement groove 23, when the workpiece 5 is squeezed by the pressure plate 31 and is close to the inner wall of the placement groove 23, the side of the workpiece 5 close to the end of the welding robot 11 will be in close contact with the blocking piece 24. At this time, since the blocking piece 24 is elastic and the blocking piece 24 is tilted downward, the blocking piece 24 will cause the workpiece 5 to be subjected to a downward force while elastically deforming, thereby ensuring that the workpiece 5 can stay stably in the placement groove 23, thereby avoiding uneven force on the workpiece 5 during the process of clamping and fixing the workpiece 5 by the pressure plate 31, causing the workpiece 5 to burst out of the placement groove 23 or the workpiece 5 to move after being fixed, affecting the fixing and positioning effect of the workpiece 5, and further affecting the welding effect and welding speed of the workpiece 5.

[0052] As an embodiment of the present invention, a blow pipe 4 is installed on the workbench 1, and the blow pipe 4 is aimed at the workpiece 5 in the placement groove 23;

[0053] The positions of the air blowing pipe 4 and the lifting block 26 correspond to each other;

[0054] When the lifting seat 22 is lifted up by the lifting block 26, the workpiece 5 is also blown through the air blowing pipe 4, so that the workpiece 5 is pushed by the airflow, and the workpiece 5 is promoted to slide and approach the end of the placement groove 23 close to the welding manipulator 11, so as to avoid the workpiece 5 from being displaced greatly when the pressing plate 31 clamps and fixes the workpiece 5, thereby affecting the fixing effect of the workpiece 5 and the subsequent welding effect of the workpiece 5;

[0055] At the same time, since the workpiece 5 undergoes transportation and storage before welding, there may be dust and impurities on the surface of the workpiece 5, which will have an adverse effect on the subsequent welding process. At this time, the gas blown out from the blowing pipe 4 is blown on the surface of the workpiece 5 to remove the dust and impurities attached to the surface of the workpiece 5, thereby ensuring that the subsequent welding of the workpiece 5 is of good quality and fast welding speed.

[0056] As an embodiment of the present invention, the blowing pipes 4 are arranged in pairs, and the blowing pipes 4 blow the area to be welded on the workpiece 5, and the gas blown from the blowing pipes 4 counteracts the force of the workpiece 5 along the tangential direction;

[0057] By arranging the air blowing pipes 4 in pairs and symmetrically, the airflow blown out of the air blowing pipes 4 can blow the workpiece 5 in two directions respectively, so that the component force of the airflow on the workpiece 5 along the tangential direction can offset each other, avoiding the workpiece 5 from rotating under the action of the airflow, affecting the clamping and fixing effect of the workpiece 5, affecting the accurate stability of the position and angle of the workpiece 5, and affecting the subsequent welding effect and welding speed of the craftsmen.

[0058] As an embodiment of the present invention, an elastic layer 32 is installed on the pressing plate 31, and a protrusion is arranged on the surface of the elastic layer 32. The elastic layer 32 is made of a viscous silicone material;

[0059] By providing the elastic layer 32, the contact between the pressing plate 31 and the workpiece 5 is buffered to prevent the surface of the workpiece 5 from being squeezed and damaged. At the same time, since the elastic layer 32 is sticky, when the pressing plate 31 releases the squeezing and fixing of the workpiece 5, the elastic layer 32 will have a pulling effect on the workpiece 5, and cooperate with the elastic force of the positioning piece 25 to promote the workpiece 5 to stay away from the positioning piece 25, thereby facilitating the subsequent unloading of the workpiece 5.

[0060] At the same time, since the elastic layer 32 is sticky, when the pressure plate 31 and the workpiece 5 are in contact with each other, the friction between the workpiece 5 and the elastic layer 32 is relatively large, which prevents the workpiece 5 from slipping out or popping out of the placement groove 23, ensuring that the workpiece 5 is clamped and fixed well.

[0061] A high-speed negative ion hair dryer heating wire assembly welding method, the assembly welding method is applicable to any one of the above-mentioned high-speed negative ion hair dryer heating wire assembly welding devices, the assembly welding method comprises the following steps:

[0062] S1: Start the conveyor belt 12 motor, and place the heating wire workpiece 5 wound on the mica sheet into the placement groove 23 manually or by a robot;

[0063] S2: The conveyor belt 12 drives the fixed frame 2 to move, so that the lifting block 26 passes through the lifting slide groove 221, so that the lifting seat 22 is lifted from the horizontal state and then restored to the horizontal state, so that the workpiece 5 in the placement groove 23 slides toward the end close to the welding robot 11 and approaches the side wall of the placement groove 23 close to the end of the welding robot 11;

[0064] S3: After the conveyor belt 12 drives the fixing frame 2 to the position of the welding robot 11, the cylinder 3 is controlled to move, so that the pressing plate 31 extends into the placement groove 23, and the pressing plate 31 contacts and presses the workpiece 5, so that the workpiece 5 is fixed and positioned, and then the welding robot 11 is controlled by the controller to weld the workpiece 5;

[0065] S4: After the welding of the workpiece 5 is completed, the welding robot 11 returns to its original position first, and the cylinder 3 drives the pressure plate 31 back to its original position to release the fixation of the workpiece 5. After that, the conveyor belt 12 drives the workpiece 5 away from the welding robot 11 so that the welded workpiece 5 can be unloaded manually or by a robot.

[0066] The specific workflow is as follows:

[0067] The heating wire is placed in the placement slot 23 manually or by a robot, and then the motor of the conveyor belt 12 is started by the controller, so that the conveyor belt 12 drives the heating wire workpiece 5 to move toward the welding robot 11. Then, when the heating wire reaches the position of the welding robot 11, the cylinder 3 drives the pressing plate 31 to extend, so that the pressing plate 31 clamps and fixes the workpiece 5 in the placement slot 23. Then, after the welding of the workpiece 5 is completed, the welding robot 11 and the cylinder 3 return to their original positions, and the conveyor belt 12 drives the heating wire to leave and unload the workpiece 5.

[0068] At the same time, when the fixing frame 2 passes through the area where the lifting block 26 is located, the lifting block 26 will pass through the lifting slot 221, and the lifting seat 22 will be lifted upward by the shape of the lifting block 26 itself, that is, the placement slot 23 is tilted toward the direction of the welding manipulator 11, so that the workpiece 5 in the placement slot 23 is close to the inner wall of the placement slot 23 at one end close to the welding manipulator 11, avoiding the workpiece 5 from being relatively displaced when the cylinder 3 drives the pressure plate 31 to clamp and fix the workpiece 5;

[0069] At the same time, since the inner wall of the placement groove 23 is smooth, it is convenient for the workpiece 5 to slide in the placement groove 23 toward the end close to the welding robot 11;

[0070] At the same time, the thickness of one end of the lifting block 26 facing the welding robot 11 is smaller than that of the other end, so that the upper surface of the lifting block 26 is an inclined surface, so that the upper surface of the lifting block 26 and the lifting chute 221 can match each other;

[0071] At the same time, on the assembly welding device, along the moving direction of the conveyor belt 12, there are the area where the workpiece 5 is placed, the area where the lifting seat 22 is lifted by the lifting block 26, the area where the workpiece 5 is clamped and fixed by the pressing plate 31 and welded, and the area where the welded workpiece 5 is unloaded, and at the same time, the various areas will not overlap with each other;

[0072] After the conveyor belt 12 drives the workpiece 5 to the position of the welding manipulator 11, the conveyor belt 12 temporarily stops moving, and then the cylinder 3 drives the pressing plate 31 to squeeze the workpiece 5, so that the end of the workpiece 5 close to the welding manipulator 11 is close to the side wall of the placement groove 23. At this time, the positioning piece 25 in the placement groove 23 will be inserted into the gap between the mica sheets on the workpiece 5, so that the positioning piece 25 squeezes the mica sheets on both sides of the gap at the same time, so that the gap and the positioning piece 25 are aligned with each other, and the angle of the workpiece 5 is corrected and fixed by using the symmetrically arranged and elastic positioning pieces 25 to ensure that the position and angle of the workpiece 5 in the placement groove 23 are accurate;

[0073] When the workpiece 5 is pressed and fixed by the pressing plate 31 and the positioning piece 25 is inserted into the notch on the workpiece 5, the positioning piece 25 makes line contact or point contact with the mica sheets on both sides of the notch on the workpiece 5 through the effect of the protruding lines 251 on the surface, thereby reducing the friction between the positioning piece 25 and the workpiece 5;

[0074] At the same time, after the welding of the workpiece 5 is completed and the clamping plate 31 releases the clamping fixation of the workpiece 5, the workpiece 5 can be easily pushed in a direction away from the welding manipulator 11 under the elastic action of the positioning piece 25, so that the workpiece 5 can be automatically released from the positioning of the positioning piece 25;

[0075] At the same time, since the positioning piece 25 is arc-shaped and elastic, when the pressing plate 31 clamps the workpiece 5, the workpiece 5 will first contact the positioning piece 25, and the positioning piece 25 will buffer the contact between the workpiece 5 and the inner wall of the placement groove 23;

[0076] Since the blocking sheet 24 is installed on the inner wall of the placement groove 23, when the workpiece 5 is pressed close to the inner wall of the placement groove 23 by the pressing plate 31, the side of the workpiece 5 close to the end of the welding robot 11 will be in close contact with the blocking sheet 24. At this time, since the blocking sheet 24 is elastic and the blocking sheet 24 is tilted downward, the blocking sheet 24 will cause the workpiece 5 to be subjected to a downward force while the blocking sheet 24 is elastically deformed, thereby ensuring that the workpiece 5 can stably stay in the placement groove 23;

[0077] When the lifting seat 22 is lifted by the lifting block 26, the workpiece 5 is also blown through the air blowing pipe 4, so that the workpiece 5 is pushed by the air flow, and the workpiece 5 is promoted to slide and approach the end of the placement groove 23 close to the welding robot 11;

[0078] At the same time, the gas blown out from the air blowing pipe 4 is blown to the surface of the workpiece 5 to remove dust and impurities attached to the surface of the workpiece 5;

[0079] By arranging the air blowing pipes 4 in pairs and symmetrically, the airflow blown out of the air blowing pipes 4 can blow the workpiece 5 in two directions respectively, so that the component forces along the tangential direction that the airflow may generate on the workpiece 5 can offset each other, thereby preventing the workpiece 5 from rotating under the action of the airflow;

[0080] By providing the elastic layer 32, the contact between the pressing plate 31 and the workpiece 5 is buffered to prevent the surface of the workpiece 5 from being squeezed and damaged. At the same time, since the elastic layer 32 is sticky, when the pressing plate 31 releases the squeezing and fixing of the workpiece 5, the elastic layer 32 will have a pulling effect on the workpiece 5, and cooperate with the elastic force of the positioning piece 25 to promote the workpiece 5 to stay away from the positioning piece 25.

[0081] At the same time, since the elastic layer 32 is sticky, when the pressing plate 31 and the workpiece 5 are in contact with each other, the friction between the workpiece 5 and the elastic layer 32 is relatively large, thereby preventing the workpiece 5 from sliding out or popping out of the placement groove 23 .

[0082] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
