Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding stator product production, and specifically relates to an adjustable ultrasonic welding tool. Background Art

[0002] Injection molded stators refer to stator parts manufactured by injecting molten plastic into a mold through an injection nozzle using an injection molding machine during the injection molding process. Injection molded stators are usually used in motors, generators, power tools and other equipment.

[0003] In the production process of injection molded stator products, it is necessary to use an automatic winding machine to carry out automatic winding. After winding, the lead wire of the injection molded stator core needs to be fixed. The method is to use an ultrasonic welding gun to melt and weld the plastic at a specific position on the injection molded stator core, so as to fix the lead wire in the plastic slot at a specific position to prevent the lead wire from loosening and causing the wire to fall off and be exposed. However, in the actual production and use process, it is manually welded by the operator. The specific method is that the worker holds the ultrasonic welding gun and presses the gun head of the ultrasonic welding gun vertically from top to bottom on the plastic at a specific position of the injection molded stator core. This method often causes various problems, resulting in a low yield of the product; in addition, products with different slot numbers, different outer circles, and different height requirements require a tooling for each product, which is costly, not conducive to storage, and workers are easily confused; in response to the above problems, an adjustable ultrasonic welding tooling is proposed.

[0012] Beneficial effects of the utility model:

[0013] The biggest advantage of this new welding tool is that it greatly improves the yield of the product. The new tool limits the height and position that the ultrasonic welding gun can be lowered, which is equivalent to limiting the welding point. In this way, workers will not cause various damage problems caused by excessive force or skewed force when operating as in the past;

[0014] The new welding tool uses several structural parts to limit the welding points, that is, a simple operation mode makes the use of the tool easy to understand, lowers the threshold for workers to use the tool, and also reduces the cost and effort spent on early training of workers. Through the centering fixture, it can meet the fixation of injection molded stator cores of different sizes;

[0015] The base, structural parts and ultrasonic welding gun of the tooling are all detachable and replaceable, which avoids the embarrassment of not being able to replace the subsequent outlet tooling in time when it is damaged or worn. And for different types of products, it is also very important to replace different accessories in a timely, fast and convenient manner;

[0016] The new welding tool has a simple structure and is easy to understand. It does not require too much energy and time to debug, inspect and repair the tool itself in the future, which is convenient and quick.

[0017] This new welding tool can ensure the stability and consistency of the product, avoiding various problems caused by manual welding in the past. Therefore, when inspecting the product at this step, only the initial inspection and random inspection are required, saving a lot of inspection time;

[0018] This new welding tool greatly reduces the welding time of workers, reduces the time cost, and also reduces the labor cost in disguise, and also reduces the fatigue of workers;

[0019] The new welding tooling has more standardized use of ultrasonic waves, because the welding points are limited, and it is less likely to cause damage to the ultrasonic welding gun, thereby increasing the service life of the ultrasonic welding gun and reducing the cost of subsequent maintenance;

[0020] This new welding tool is simple and practical, and the operating principle is easy to understand. Not only does it feel convenient and quick for users to use, but the personnel who write the tool operation instructions will also find it very simple, which also greatly saves the 6s maintenance time.

[0021] 9. This new tooling uses reasonable materials, has low cost, takes less time to process, and saves more manpower and material resources. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0032] Please see all instructions drawings:

[0033] An adjustable ultrasonic welding tool comprises an injection molded stator core 1, a base 2 and a bracket 3, wherein the bracket 3 is fixed on the base 2 by means of a screw and a nut, and an adjustable welding assembly is arranged between the base 2 and the bracket 3;

[0034] From the above description, it can be seen that the base 2 and the bracket 3 can be disassembled and replaced, which is convenient for adjusting the welding of products of different heights and sizes;

[0035] The adjustable welding assembly includes a centering fixture 4 located on a base 2, an injection molded stator core 1 is located in the centering fixture 4, a structural member 1 5 is provided on a bracket 3, a support rod 1 6 is rotatably provided on the structural member 1 5, a bolt 1 7 is provided between the structural member 1 5 and the support rod 1 6, a structural member 2 8 is rotatably provided on the support rod 1 6, a bolt 2 9 is provided between the support rod 1 6 and the structural member 2 8, a support rod 2 10 is hingedly provided on the structural member 2 8, a connecting shaft 11 is rotatably provided on the support rod 2 10, springs 12 are symmetrically provided at both ends of the connecting shaft 11, the other end of the spring 12 is sleeve-connected with the structural member 2 8, a structural member 3 13 is hingedly provided at the other end of the support rod 2 10, a stabilizing rod 14 is hingedly provided between the structural member 2 8 and the structural member 3 13, a chuck 15 is symmetrically provided on the side of the structural member 3 13 away from the support rod 2 10, and an ultrasonic welding gun 16 is provided between the chucks 15;

[0036] From the above description, it can be seen that before welding, the angle and height should be adjusted according to the product conditions. After adjustment, it can be seen that the relative positions of the ultrasonic welding gun 16, the injection molded stator core 1 and the entire equipment are fixed at this time, and the ultrasonic welding gun 16 can only be lowered to the position as shown in the figure. Figure 1The position shown in the figure is exactly the position where the specific plastic position of the injection molded stator core 1 needs to be welded; after the welding is completed, the worker releases the hand holding the ultrasonic welding gun 16, and the ultrasonic welding gun 16 will freely return to the original position under the tension of the spring 12, as shown in the figure. Figure 2 As shown;

[0037] Structural member 1 5 , structural member 2 8 and structural member 3 13 can rotate freely and move up and down, but the position is fixed for a single product; for injection molded stator cores 1 with different outer circle sizes, different heights and different numbers of slots, the welding positions are also different, and at this time, the flexibility of structural member 1 5 , structural member 2 8 and structural member 3 13 comes into play; structural member 1 5 , structural member 2 8 and structural member 3 13 can change the corresponding height, rotation angle, extreme position and other parameters at any time according to the size of the injection molded stator core 1 , and after adjustment, ultrasonic welding can be performed in the same way as conventional methods, which is very convenient; and the adjustment of structural member 1 5 , structural member 2 8 and structural member 3 13 is also very simple, and workers can adjust them by themselves after simple training, saving a lot of time and energy spent on making different types of tooling, and also reducing the cost of making tooling.

[0038] As a technical optimization solution of the utility model, the ultrasonic welding gun 16 includes an ultrasonic gun handle 1601, and the ultrasonic gun handle 1601 is provided with an air pipe 1602 and an ultrasonic gun button 1603;

[0039] From the above description, it can be seen that when using, the worker holds the ultrasonic gun handle 1601 with the right hand, presses the ultrasonic gun button 1603 with the right index finger to perform ultrasonic welding, presses the switch for about 2 seconds and then releases it, and repeats steps 3-7 until welding is completed at all positions.

[0040] As a technical optimization solution of the utility model, a bolt 3 17 is provided on the chuck 15, and the bolt 3 17 is threadedly connected to the ultrasonic gun handle 1601;

[0041] From the above description, it can be known that the chuck 15 is fixed to the ultrasonic gun handle 1601 by means of the bolt 3 17 .

[0042] As a technical optimization solution of the utility model, the second support rod 10 is arranged in parallel with the stabilizing rod 14, and the second support rod 10 and the stabilizing rod 14 have the same length;

[0043] It can be seen from the above description that the support rod 10 , the stabilizing rod 14 , the second structural member 8 and the third structural member 13 form a parallelogram structure, which can achieve corresponding stability under the pulling of the spring 12 .

[0044] As a technical optimization solution of the utility model, a plurality of adjustment holes 18 are evenly arranged on the support rod 10, and the adjustment holes 18 and the connecting shaft 11 fit each other;

[0045] It can be seen from the above description that the adjustment hole 18 can meet the use of different springs 12 or adjust the rebound speed of the ultrasonic welding gun 16.

[0046] As a technical optimization solution of the utility model, a bolt 4 19 is provided on the structural member 1 5;

[0047] From the above description, it can be seen that the bolt four 19 can meet the needs of rapid disassembly and adjustment of the structural member 5.

[0048] As a technical optimization solution of the utility model, a plurality of sound insulation pads 20 are evenly arranged on the lower side of the base 1;

[0049] From the above description, it can be seen that the entire working environment can be optimized.

[0050] Working principle:

[0051] First, turn on the main switch of the ultrasonic welding gun 16, prepare the injection molded stator core 1 with the lead wire connected, distinguish the front and back sides, put the end without the lead wire on the back side in the centering fixture 4 of the base 1, and fix it. The limit position of the ultrasonic welding gun 16 is limited by adjusting the structural member 1 5, the structural member 2 8 and the structural member 3 13. This limit position is the position where the worker uses ultrasonic welding. Therefore, the worker only needs to pull the ultrasonic welding gun 16 down to the limit position where the structural member 1 5, the structural member 2 8 and the structural member 3 13 cooperate, and then start welding directly. After welding is completed, you only need to release the ultrasonic welding gun 16 in your right hand and let the ultrasonic welding gun 16 return to the original position in a free state. This is a very fool-proof method, which greatly reduces the difficulty of operation for workers. Workers do not need to hold the ultrasonic welding gun 16 in their right hand all the time when welding a large amount, which reduces the fatigue of workers. At the same time, this principle also greatly improves the stability of welding products. Because the position of each descent is the same, the welding points are relatively consistent, the yield of the product is greatly improved, and the time and energy spent on subsequent problems such as welding damage to the lead wires is reduced.

[0052] The above describes the utility model and its implementation methods, which are not restrictive. The specific implementation method is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
