High-frequency transformer conveying line

Abstract

The utility model relates to the technical field of transformer production and manufacturing, in particular to a high-frequency transformer conveying line which comprises a conveyor, an accompanying jig, a stopping mechanism and a turnover mechanism. The accompanying jig is used for bearing the high-frequency transformer and is carried by the conveyor. When the high-frequency transformer flows through the overturning station, the stopping mechanism acts to apply opposite side thrust to the accompanying jig, the accompanying jig stops flowing, and at the moment, the overturning mechanism picks up the high-frequency transformer and circumferentially overturns the high-frequency transformer by 180 degrees. Thus, on one hand, the overturning mechanism can quickly pick up the high-frequency transformer and conduct 180-degree circumferential overturning, and compared with a manual overturning mode or other low-efficiency overturning modes, the consumed time needed by overturning is greatly shortened; and on the other hand, through the synergistic effect of the conveyor, the accompanying jig, the stopping mechanism and the turnover mechanism, the position of the high-frequency transformer on the turnover station is accurate and stable, and the precision and quality of follow-up ink jet coding can be improved.

Description

Technical Field

[0001] This utility model relates to the field of transformer manufacturing technology, and in particular to a high-frequency transformer transmission line. Background Technology

[0002] High-frequency transformers operate primarily based on the principle of electromagnetic induction and are widely used in switching power supplies, electronic ballasts, high-frequency inverter welding machines, and other fields. When a high-frequency alternating current is applied to the primary winding, an alternating magnetic field is generated. This alternating magnetic field is coupled to the secondary winding through the magnetic core, inducing an electromotive force in the secondary winding, thereby realizing the transfer of electrical energy from the primary to the secondary winding.

[0003] During the production phase in the workshop, the high-frequency transformer is directionally rotated under the conveyor force, sequentially passing through the product performance testing station and the inkjet marking station. The testing surface is usually located on the end face of the high-frequency transformer, while the inkjet marking surface is located on the magnetic core surface of the product. This means that after performance testing, the high-frequency transformer needs to be rotated 180° to facilitate the inkjet marking operation. Currently, one worker is assigned between the product performance testing station and the inkjet marking station specifically to perform the 180° rotation of the high-frequency transformer. However, in practice, the following problems exist: 1) Manual product flipping is relatively slow, especially in mass production or when frequent flipping is required. Manual operation is difficult to meet the production cycle requirements, slowing down the entire production process; 2) Operators' techniques, strength, and angles will inevitably vary during long-term product flipping, leading to inconsistent product states and affecting subsequent inkjet coding quality; 3) Operators are prone to fatigue due to prolonged repetitive product flipping operations, harming their health, and incurring significant labor costs. Therefore, it is urgent for technical personnel to solve these problems. Utility Model Content

[0004] Therefore, in view of the above-mentioned existing problems and defects, the designers of this utility model collected relevant information, conducted multiple evaluations and considerations, and carried out continuous experiments and modifications by technical personnel with many years of R&D experience in this industry, which ultimately led to the emergence of this high-frequency transformer transmission line.

[0005] This utility model relates to a high-frequency transformer conveyor line, in which batches of high-frequency transformers flow sequentially through an inkjet marking station under the action of conveying force. The high-frequency transformer conveyor line includes a conveyor, a traveling fixture, a stopping mechanism, and a flipping mechanism. The traveling fixture carries the high-frequency transformers and is transported by the conveyor. The stopping mechanism activates the moment the high-frequency transformers pass through the flipping station to apply a counter-lateral thrust to the traveling fixture, thus pausing its flow. The flipping mechanism picks up and rotates the high-frequency transformers 180° circumferentially; it is located on one side of the conveyor.

[0006] As a further improvement to the technical solution disclosed in this utility model, the stopping mechanism consists of a front pushing device and a rear pushing device. The front pushing device and the rear pushing device are respectively arranged in front of and behind the conveyor, and are positioned opposite each other. At the instant when the high-frequency transformer flows through the flipping station, the front pushing device and the rear pushing device act simultaneously to apply lateral pushing force to the front and rear side walls of the accompanying fixture, respectively.

[0007] As a further improvement to the technical solution disclosed in this utility model, the front pushing device and the rear pushing device have the same design structure. The front pushing device includes a front support seat, a front pushing cylinder, and a front pushing plate. The front pushing cylinder uses the front support seat as its mounting base. The front pushing plate is brought close to the accompanying fixture by the driving force from the front pushing cylinder.

[0008] As a further improvement to the technical solution disclosed in this utility model, the front pushing device also includes a front plastic pad. The front plastic pad is in contact with the front pushing plate and is fixed as a whole in a detachable manner. During the translational movement of the front pushing plate, the front plastic pad approaches and non-rigidly contacts the accompanying fixture.

[0009] As a further improvement to the technical solution disclosed in this utility model, the flipping mechanism includes a base, a vertical cylinder, a rotary cylinder, a parallel finger cylinder, and a transition plate. The vertical cylinder is used to load the transition plate, and it is placed and fixed on the base. The parallel finger cylinder is combined with the rotary cylinder and is installed as a whole on the transition plate.

[0010] As a further improvement to the technical solution disclosed in this utility model, the flipping mechanism also includes a guide unit. With the assistance of the guide unit, the transition plate performs a directional lifting and lowering movement along the height direction due to the drag force from the vertical cylinder.

[0011] As a further improvement to the technical solution disclosed in this utility model, the guide unit consists of a left-side guide assembly and a right-side guide assembly. The left-side guide assembly and the right-side guide assembly have the same design structure and installation method. The left-side guide assembly includes a left-side guide post and a left-side guide sleeve. The left-side guide post is vertical and is placed and fixed on the base. The left-side guide sleeve uses the left-side guide post as its mounting base and is detachably connected to the transition plate.

[0012] In practical applications, the high-frequency transformer transmission line disclosed in this utility model can achieve at least the following beneficial technical effects, specifically:

[0013] 1) Through the coordinated action of the conveyor, the accompanying fixture, the stopping mechanism and the flipping mechanism, the high-frequency transformer is positioned accurately and stably at the flipping station. This helps to improve the accuracy and quality of subsequent inkjet coding, ensuring clear and accurate coding, and avoiding problems such as unclear coding and misalignment caused by the position deviation of the high-frequency transformer.

[0014] 2) The conveyor can continuously and stably transport high-frequency transformers in batches, allowing them to flow sequentially through the inkjet marking station, ensuring production continuity. Furthermore, at the flipping station, the stopping mechanism can precisely pause the movement of the accompanying fixture, laying a good foundation for the subsequent smooth implementation of a 180° precise flipping operation.

[0015] 3) The flipping mechanism can quickly pick up the high-frequency transformer and flip it 180° circumferentially. Compared with manual flipping or other inefficient flipping methods, it greatly shortens the time required for flipping and further improves the production cycle of high-frequency transformers.

[0016] 4) Depending on the different models of the pre-inkjet coding high-frequency transformer, the accompanying fixtures can be easily and quickly changed, making the conveyor line suitable for a variety of high-frequency transformers and improving the flexibility of production organization.

Detailed Implementation

[0025] In the description of this utility model, it should be understood that the terms "left", "right", "front", "back", "up", "down", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 , Figure 2The diagram shows the structure of the high-frequency transformer conveyor line disclosed in this utility model. It is mainly composed of a conveyor 1, a traveling fixture 2, a stopping mechanism 3, and a flipping mechanism 4. The traveling fixture 2 carries the high-frequency transformers and is transported by the conveyor 1. Under the conveying force of the conveyor 1, batches of high-frequency transformers flow sequentially through the inkjet marking station. The stopping mechanism 3 activates at the flipping station to apply a lateral push to the traveling fixture, pausing its rotation. The flipping mechanism 4 picks up and rotates the high-frequency transformers 180°, and is located on one side of the conveyor 1. After the high-frequency transformers have completed their 180° rotation, the stopping mechanism 3 releases its lateral push on the traveling fixture 2, allowing it to resume rotation under the renewed conveying force from the conveyor 1, eventually reaching the inkjet marking station.

[0027] By adopting the above technical solution, on the one hand, the coordinated action of conveyor 1, accompanying fixture 2, stopping mechanism 3, and flipping mechanism 4 ensures that the high-frequency transformer is accurately and stably positioned at the flipping station. This helps improve the accuracy and quality of subsequent inkjet coding, ensuring clear and accurate coding marks and avoiding problems such as unclear or misaligned coding caused by high-frequency transformer position deviation. On the other hand, conveyor 1 can continuously and stably transport high-frequency transformers in batches, allowing them to flow sequentially through the inkjet coding station, ensuring production continuity. Furthermore, at the flipping station, stopping mechanism 3 can precisely pause the movement of accompanying fixture 2, laying a good foundation for the smooth implementation of subsequent 180° precise flipping operations.

[0028] like Figure 3 As shown, the accompanying fixture 2 is provided with a receiving groove that is adapted to the shape of the high-frequency transformer body to ensure that the high-frequency transformer body always maintains a stable posture during the transportation process.

[0029] It is particularly important to note that in practical applications, the accompanying fixture 2 can be easily and quickly replaced according to the different models of the pre-inkjet coding high-frequency transformer, making the conveyor line suitable for various high-frequency transformers and improving the flexibility of production organization.

[0030] Depend on Figure 2 As can be clearly seen from the diagram, the stopping mechanism 3 consists of a front pushing device 31 and a rear pushing device 32. The front pushing device 31 and the rear pushing device 32 are respectively arranged in front of and behind the conveyor 1, and are positioned opposite each other. At the instant the high-frequency transformer flows through the flipping station, the front pushing device 31 and the rear pushing device 32 act simultaneously to apply lateral pushing forces to the front and rear side walls of the accompanying fixture 2, respectively.

[0031] like Figure 4As shown, the front pushing device 31 includes a front support seat 311, a front pushing cylinder 312, and a front pushing plate 313. The front pushing cylinder 312 uses the front support seat 311 as its mounting base. The front pushing plate 313 is brought close to the accompanying fixture 2 by the driving force from the front pushing cylinder 312.

[0032] Furthermore, by Figure 4 As can be clearly seen from the diagram, the rear pushing device 32 and the front pushing device 31 have the same design structure. The rear pushing device 32 includes a rear support base 321, a rear pushing cylinder 322, and a rear pushing plate 323. The rear pushing cylinder 322 uses the rear support base 321 as its mounting base. The rear pushing plate 323 is brought close to the accompanying fixture 2 by the driving force from the rear pushing cylinder 322.

[0033] After a period of operation, the front and rear sidewalls of the accompanying fixture 2 suffer severe wear due to frequent rigid contact with the front push plate 313 and the rear push plate 323, which inevitably affects the positioning accuracy of the accompanying fixture 2 and makes it prone to tilting. Therefore, as a further optimization of the above technical solution, such as... Figure 4 As shown, the front pushing device 31 is further provided with a front plastic pad 314. The front plastic pad 314 is in contact with the front pushing plate 313 and is fixed together in a detachable manner. The rear pushing device 32 is further provided with a rear plastic pad 324. The rear plastic pad 324 is in contact with the rear pushing plate 323 and is fixed together in a detachable manner. During the process of the front pushing plate 313 and the rear pushing plate 323 performing opposing translational movements, the front plastic pad 314 and the rear plastic pad 324 can gradually approach and non-rigidly contact the accompanying fixture 2.

[0034] It is known that, based on design common sense, the flipping mechanism 4 can adopt various design structures to achieve the 180° flipping operation of the high-frequency transformer. However, here we recommend an implementation scheme that is simple in design, easy to manufacture and implement, quick and efficient in flipping action, and has excellent flipping accuracy. Specifically, it is as follows: Figure 5 , Figure 6 As shown, the flipping mechanism 4 mainly consists of a base 41, a vertical cylinder 42, a rotary cylinder 43, a parallel finger cylinder 44, and a transition plate 45. The vertical cylinder 42 supports the transition plate 45 and uses the base 41 as its placement and fixing foundation. The parallel finger cylinder 44 is combined with the rotary cylinder 43 and mounted as a whole on the transition plate 45. In this way, the flipping mechanism 4 can quickly pick up the high-frequency transformer and perform a 180° circumferential flip, significantly reducing the flipping time compared to manual flipping or other inefficient methods, further improving the production cycle of the high-frequency transformer.

[0035] In practical applications, after the accompanying fixture 2 has finished stopping relative to the flipping station, the high-frequency transformer it carries is aligned with the parallel finger cylinder 44. At this time, the transition plate 45 moves downward due to the dragging force from the vertical cylinder 42. Simultaneously, the parallel finger cylinder 44 gradually approaches the high-frequency transformer and stops at the designed height. Then, the parallel finger cylinder 44 performs a finger opening and closing movement due to the pneumatic force to clamp the high-frequency transformer. Subsequently, the vertical cylinder 42 reverses its movement to drag the transition plate 45 upward, allowing the high-frequency transformer to be released from the accompanying fixture 2 and continue to rise a certain distance. Then, the rotary cylinder 43 is activated, and the parallel finger cylinder 44 performs a 180° circumferential rotation due to the rotational torque. During this process, the high-frequency transformer completes a 180° circumferential flipping action.

[0036] Furthermore, similarly Figure 5 , Figure 6 As shown, the flipping mechanism 4 is further equipped with a guide unit 46. With the assistance of the guide unit 46, the transition plate 45 performs a directional lifting and lowering movement along the height direction due to the drag force from the vertical cylinder 42, thereby facilitating the accurate alignment of the parallel finger cylinder 44 with the high-frequency transformer. The guide unit 46 consists of a left guide assembly 461 and a right guide assembly 462. The left guide assembly 461 includes a left guide post 4611 and a left guide sleeve 4612. The right guide assembly 462 includes a right guide post 4621 and a right guide sleeve 4622. Both the left guide post 4611 and the right guide post 4621 are in an upright state and are placed and fixed on the base. The left guide sleeve 4612 and the right guide sleeve 4622 are respectively fitted with the left guide post 4611 and the right guide post 4621 as the mounting base, and both are detachably connected to the transition plate 45.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
