Description

Technical Field

[0001] The invention belongs to the technical field of network transformer production, and particularly relates to a network transformer foot winding machine and a foot winding method thereof. Background Art

[0002] During the processing of network transformers, a winding process is required, that is, wrapping the wire around the pins. Currently, most companies still use wire management tools in conjunction with manual methods to wrap the pins. The invention patent application with application number CN102832039A discloses a network transformer wire management tool, which uses a base strip to clamp the pins and then manually clamp the wire ends and wrap them around the corresponding pins. The processing quality of manual winding not only depends on the operator's operating level, but also has low processing efficiency, making it difficult to meet the production needs of large enterprises.

[0003] Therefore, manufacturers have developed automatic pin-winding machines to improve product processing efficiency. However, after the pins are wound, there are often extra flying wires on the pins of network transformer products, which need to be cut off.

[0004] At present, there are two main methods for pulling off the flying wire ends: manual pulling or automatic machine pulling. Manual pulling not only involves a large workload, but also has very low processing efficiency. In addition, due to differences in workers' skills, it is difficult to achieve standardization in the control of force and direction when pulling the wire ends, which in turn causes an increase in product defective rates and increases the company's production costs. Machine pulling improves wire pulling efficiency, but most existing wire pulling mechanisms use downward pressure components of fixed size and structure to fix the products to be pulled. When pulling network transformer products of different sizes and models, there may be problems with unreliable fixation, which also causes an increase in product defective rates. In addition, when existing companies carry out processes such as product loading, product foot wrapping, and product flying wire processing, products need to be transported back and forth on multiple production lines. The overall production coordination and fluidity are poor, and production efficiency still needs to be improved.

[0005] Therefore, it is necessary to develop a highly integrated and intelligent network transformer foot winding machine that fully covers the production processes such as loading, foot winding, flying wire cleaning, finished product inspection, and material collection, so as to improve product production efficiency, ensure product production smoothness, reduce product defective rate, and ensure that the company completes production with quality and quantity. Summary of the Invention

[0050] Furthermore, a thimble cylinder is provided on the second frame beside the first positioning slide.

[0051] Furthermore, a storage box for defective feet is provided on the chassis.

[0052] A method for winding a network transformer foot using a foot winding machine comprises the following steps:

[0053] S1, place the network transformer product to be wound on the feeding conveyor line, and the feeding conveyor line continuously conveys the network transformer product to the end of the feeding conveyor line and enters S2;

[0054] In step S2, the material handling mechanism transports the network transformer product to be wound to the winding linear module, which then conveys the network transformer product to the winding mechanism. The winding mechanism winds the network transformer product. After the winding is completed, the winding linear module conveys the wound network transformer product to the end of the winding linear module, and the process proceeds to step S3.

[0055] In step S3, the material handling mechanism carries the wound network transformer product to the secondary clamping mechanism of the tail wire cleaning mechanism for clamping. The tail wire cleaning mechanism then tears off the excess tail wires on the pins of the wound network transformer product, and the process proceeds to step S4.

[0056] S4, the material handling mechanism transports the network transformer products with cleaned tail wires to the finished product sorting module, which tests the network transformer products. If the test result is unqualified, the process proceeds to step S5; if the test result is qualified, the process proceeds to step S6;

[0057] S5, the finished product handling mechanism of the branch line places the unqualified network transformer products into the bad foot storage box;

[0058] S6, the branch base transport mechanism places the base plate on the finished product sorting module, and the branch finished product transport mechanism places the qualified network transformer product on the base plate, completing the assembly and entering step S7;

[0059] S7, the finished product receiving mechanism of the sub-line collects the assembled network transformer products and completes the foot wrapping work of the network transformer products.

[0060] During the implementation of the present invention, first, a network transformer product to be wound is placed on a feeding conveyor line, which continuously conveys the network transformer product to the end of the feeding conveyor line. The incoming material transport mechanism transports the network transformer product to be wound to a winding linear module, which then transports the network transformer product to the winding mechanism.

[0061] Specifically, before the winding mechanism begins winding, a lifting motor drives the winding assembly up and down to adjust the height of the winding assembly and subsequently position the winding needle. During winding, the lifting motor drives the winding motor and the winding needle downward, allowing the winding needle to hook the thread end. The output end of the winding motor, through a coupling and a gear set, drives the winding needle to rotate. After the thread end is hooked on the needle, the lifting motor drives the winding motor and the winding needle to rise and reset. After the winding cycle is completed, the winding process ends. This greatly improves the efficiency of the network transformer winding process, increases the degree of automation, and solves the problem of low efficiency in existing network transformer winding processes.

[0062] As a preferred embodiment, a lift origin sensor is further provided on the first frame above the lift motor. With this arrangement, after the foot winding assembly completes height adjustment and positioning, the lift origin sensor is used to sense the lift origin of the foot winding assembly during the foot winding operation, ensuring accurate reset of the foot winding assembly during the reciprocating movement.

[0063] As a preferred embodiment, the winding assembly is further provided with a winding origin sensor located above the winding motor. This arrangement facilitates sensing the initial point of rotation of the winding needle, ensuring that the winding needle rotates at a fixed angle when winding the foot, thereby ensuring the accuracy of the winding.

[0064] Then, the incoming material handling mechanism carries the wound network transformer product to the secondary clamping mechanism of the tail wire cleaning mechanism for clamping, and the tail wire cleaning mechanism tears off the excess tail wires on the pins of the wound network transformer product.

[0065] Specifically, the secondary clamping mechanism clamps the network transformer product to be pulled. The output end of the telescopic cylinder extends forward, driving the clamping cylinder to move to the flying wire of the network transformer product. The output end of the clamping cylinder drives the clamping cylinder to grab the excess flying wire ends. The telescopic cylinder retracts, driving the clamping cylinder away from the network transformer product, and finally breaking the excess flying wire ends, completing the wire pulling process. By adopting a mechanized, intelligent, and refined wire pulling method, not only is the efficiency of handling flying wires of network transformer products greatly improved, but it also avoids product defects caused by manual wire pulling, saving the company's production costs.

[0066] As a preferred embodiment, the secondary clamping mechanism includes a base plate installed on the base plate, the base plate having a first fixed block, the first fixed block being sleeved with a first spring sliding column, the first spring sliding column being sleeved with a spring, the other end of the first spring sliding column being sleeved with a first positioning slide, the middle of the first positioning slide being provided with a slot, the base plate is also provided with a second fixed block, the second fixed block being sleeved with a second spring sliding column, the second spring sliding column being arranged perpendicularly relative to the first spring sliding column, the second spring sliding column being sleeved with a spring, the other end of the second spring sliding column being sleeved with a second positioning slide, the second positioning sliding end being clamped with the slot in the middle of the first positioning slide, a third fixed block being further installed above the first positioning slide and the second positioning slide, a fourth fixed block being further installed on the side of the third fixed block away from the second spring sliding column, the first positioning slide being provided with a first fixing protrusion near the end of the first spring sliding column, and the second positioning slide being provided with a second fixing protrusion near the end of the second spring sliding column. The first and second positioning slides are pressed against each other to move relative to each other, and the first and second positioning slides are pressed against each other to move relative to each other. The movable column moves in the direction of the movable column. With the movement of the first spring sliding, the second positioning sliding moves in the direction away from the second spring sliding column. The first fixed sliding makes the first fixed protrusion contact with the network transformer product during the movement. Under the action of the spring elastic force and the limiting action of the third fixed block, the network transformer product is clamped in the y direction. The second fixed sliding makes the second fixed protrusion contact with the network transformer product during the movement. Under the action of the spring elastic force and the limiting action of the fourth fixed block, the network transformer product is clamped in the x direction, thereby realizing secondary clamping of the network transformer product in two directions, ensuring that the network transformer product is firmly fixed and preventing the product defective rate from increasing.

[0067] As a preferred embodiment, the slot includes an inclined section and a right-angled section connected to the inclined section, and the end of the second spring slide post is provided with a bevel head that matches the inclined section. With this arrangement, when the first positioning slide moves, the inclined section contacts the bevel head, accurately defining the movement direction of the second positioning slide, ensuring that the second positioning slide moves synchronously toward the second spring slide post.

[0068] As a preferred embodiment, a thimble cylinder is provided on the second frame next to the first positioning slide. Through this arrangement, the thimble cylinder can automatically push and release the first positioning slide, making the movement of the first positioning slide more intelligent.

[0069] Finally, the incoming material handling mechanism will transport the network transformer products with the tail wires cleaned to the finished product sorting module. The finished product sorting module will test the network transformer products. If the test result is unqualified, the branch line finished product handling mechanism will place the unqualified network transformer products in the bad foot winding storage box; if the test result is qualified, the branch line base handling mechanism will place the bottom plate on the finished product sorting module, and the branch line finished product handling mechanism will place the qualified network transformer products on the bottom plate to complete the assembly. The branch line finished product receiving mechanism will collect the assembled network transformer products to complete the foot winding work of the network transformer products.

[0070] The operation of each mechanism is controlled by the touch control screen, and the loading, foot winding, tail wire cleaning, finished product sorting and material collection of network transformer products are completed automatically, intelligently and continuously, which greatly improves the foot winding efficiency of network transformer products and reduces the product defective rate. At the same time, although each mechanism is interconnected, it operates independently. While ensuring the smoothness of processing, when the equipment fails, the corresponding faulty mechanism can be replaced or repaired, reducing the maintenance cost of the equipment.

[0071] The above are the embodiments of the present invention. The foregoing are the preferred embodiments of the present invention. If the preferred implementation methods in each preferred embodiment are not obviously self-contradictory or based on a preferred implementation method, each preferred implementation method can be arbitrarily superimposed and used in combination. The embodiments and the specific parameters in the embodiments are only for the purpose of clearly describing the verification process of the invention, and are not intended to limit the scope of patent protection of the present invention. The scope of patent protection of the present invention is still subject to its claims. Any equivalent changes made using the description of the present invention should also be included in the scope of protection of the present invention.
