[0051] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0052] Please also read Figure 1 and Figure 2 The transformer core assembly tool provided by the utility model is now described. The transformer core assembly tool comprises a turntable 1, a feeding mechanism 2, two sets of limit assemblies 3 and two sets of positioning mechanisms 4.

[0053] Two rail bearing parts 11 and three core column bearing parts 12 are formed on the turntable 1; the two rail bearing parts 11 and the three core column bearing parts 12 enclose a structure in the shape of a Chinese character 'Ri' for bearing; the feeding mechanism 2 is located outside the turntable 1 and is used for sequentially feeding a plurality of silicon steel sheets onto the structure in the shape of a Chinese character 'Ri' for bearing; two groups of limiting components 3 are respectively located in two middle cavities 13 of the structure in the shape of a Chinese character 'Ri' for bearing and are used for abutting against the silicon steel sheets located on the structure in the shape of a Chinese character 'Ri' for bearing; two groups of positioning structures are oppositely arranged on both sides of the turntable 1, and the positioning mechanism 4 has the freedom to move towards and away from the turntable 1; the two groups of positioning mechanisms 4 are used for clamping the silicon steel sheets stacked on the structure in the shape of a Chinese character 'Ri' for bearing during the feeding process.

[0054] Specifically, two middle cavities 13 are formed in the part of the structure in the shape of a Chinese character 'Ri' for bearing where no silicon steel sheet is borne, and a group of limiting components 3 are respectively arranged in the two middle cavities 13.

[0055] Before work, five groups of stacked silicon steel sheets are prepared on the stock preparation table, and the two rails 7 and the three core columns 6 are assembled corresponding to the five groups of stacked silicon steel sheets one by one.

[0056] During work, first, confirm the rail bearing part 11 or the core column bearing part 12 closest to the feeding mechanism 2. Subsequently, the feeding mechanism 2 places the corresponding silicon steel sheet on the stock preparation table on the rail bearing part 11 or the core column bearing part 12. Before this, the positioning mechanism 4 is in a static state. After confirming that the feeding mechanism 2 is far away from the turntable 1, the positioning mechanism 4 works, clamps the placed silicon steel sheet, and makes the silicon steel sheet abut against the limiting component 3.至此, the positioning mechanism 4 completes the work and resets. Subsequently, the turntable 1 rotates, transfers the next rail bearing part 11 or core column bearing part 12 in front of the feeding mechanism 2, and repeats the above feeding and positioning operations.

[0057] It should be noted that after the turntable 1 rotates one circle, the feeding mechanism 2 performs a feeding operation on the two core column bearing parts 12 and the two rail bearing parts 11 on the outer periphery of the structure in the shape of a Chinese character 'Ri' for bearing, and the core column bearing part 12 in the middle of the structure in the shape of a Chinese character 'Ri' for bearing is not fed. Therefore, for the core column bearing part 12 in the middle of the structure in the shape of a Chinese character 'Ri' for bearing, the silicon steel sheets can be stacked on the core column bearing part 12 in the middle of the structure in the shape of a Chinese character 'Ri' for bearing by means of manual feeding, or after the two core column bearing parts 12 and the two rail bearing parts 11 on the outer periphery of the structure in the shape of a Chinese character 'Ri' for bearing are fed for one time, the feeding mechanism 2 performs a feeding operation on the core column bearing part 12 in the middle of the structure in the shape of a Chinese character 'Ri' for bearing alone. The specific feeding method can be adjusted according to the actual situation.

[0058] It should be noted that when the silicon steel sheets in the middle are stacked, the two tip portions thereof can be respectively inserted into the interfaces of the silicon steel sheets on the two rail bearing parts 11, so there is no need to perform too many positioning operations on the silicon steel sheets in the middle. Since the specific structure of the silicon steel sheets is well known to those skilled in the art, it will not be elaborated here. The structure of the rail 7 and the core column 6 is as follows: Figure 7 shown.

[0059] Compared with the prior art, the transformer core assembly tool provided by the utility model prevents the silicon steel sheets from being stacked on the rail bearing part 11 and the core column bearing part 12 through the feeding mechanism 2, thereby saving manpower; in particular, by arranging a limit assembly 3 on the turntable 1 to limit the silicon steel sheets, and positioning the silicon steel sheets through two groups of positioning mechanisms 4, after the feeding mechanism 2 places the silicon steel sheets on the rail bearing part 11 or the core column bearing part 12, the limit assembly 3 and the two groups of positioning mechanisms 4 cooperate to accurately position the silicon steel sheets on the Japanese-shaped bearing structure, so that the silicon steel sheets are neatly stacked together, the quality of the core is improved, manpower is saved, and work efficiency is improved.

[0060] In some embodiments, the above-mentioned limiter assembly 3 can be used as follows: Figure 1 to Figure 2 See the structure shown. Figure 1 to Figure 2 The limiting assembly 3 includes a plurality of limiting blocks 31 .

[0061] A plurality of limit blocks 31 are arranged in the middle cavity 13 . The limit blocks 31 have abutment walls 311 . The abutment walls 311 are distributed in a step-like manner. The abutment walls 311 are used to abut against the silicon steel sheets on the Japanese-shaped bearing structure.

[0062] The stepped abutment surface 311 can fit the outer side walls of the core column 6 and the rail 7, so that the limit block 31 can finely shape the stacked silicon steel sheets, thereby improving the quality of the transformer core.

[0063] In some possible implementations, the positioning mechanism 4 is as follows: Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3 The positioning mechanism 4 includes a base 41 , a transverse positioning member 42 and a longitudinal positioning member 43 .

[0064] The base 41 is arranged on one side of the turntable 1; the transverse positioning member 42 is slidably arranged on the base 41; one end of the transverse positioning member 42 is used to abut against the tip of the silicon steel sheet; the longitudinal positioning member 43 is rotatably arranged on the base 41, and one end is used to abut against the outer wall of the silicon steel sheet.

[0065] The silicon steel sheets stacked on the outer periphery of the "day"-shaped bearing structure are spliced with each other to form a "mouth"-shaped structure. Therefore, the outer side walls of the silicon steel sheets stacked on the outer periphery of the "day"-shaped bearing structure are defined as the outer side walls, and the inner side walls are defined as the inner side walls.

[0066] During operation, while the two transverse positioning members 42 move towards the turntable 1, the two longitudinal positioning members 43 rotate towards the turntable 1, so that the two transverse positioning members 42 respectively abut against the two tips of the silicon steel sheet, and the two longitudinal positioning members 43 abut against the outer side walls of the silicon steel sheet and push the silicon steel sheet to abut against the limiting block 31 at the middle cavity 13, positioning the silicon steel sheet. The positioning process is fast, which can improve the stacking efficiency of the silicon steel sheet while meeting the requirement of neatly stacking the silicon steel sheet.

[0067] In some embodiments, the above positioning mechanism 4 can adopt the structure as shown in Figure 1 and Figure 3 . Refer to Figure 1 and Figure 3 . The middle part of the longitudinal positioning member 43 is rotatably arranged on the base 41 in the up and down direction; the positioning mechanism 4 further includes a cylinder 44 and a connecting rod 45.

[0068] The cylinder 44 is arranged on the base 41; the power output end of the cylinder 44 is connected to the other end of the transverse positioning member 42; one end of the connecting rod 45 is hinged to the other end of the longitudinal positioning member 43, and the other end is hinged to the power output end of the cylinder 44.

[0069] When the cylinder 44 pushes the transverse positioning member 42 to slide towards the turntable 1, it pushes the end of the connecting rod 45 hinged to the power output end of the cylinder 44 to move towards the turntable 1, and then the connecting rod 45 pushes the hinged end of the longitudinal positioning member 43, so that the longitudinal positioning member 43 rotates around its middle part, and the other end of the longitudinal positioning member 43 moves towards the turntable 1 and abuts against the outer side wall of the silicon steel sheet.

[0070] By using one power source to make the transverse positioning member 42 and the longitudinal positioning member 43 move simultaneously and position the silicon steel sheet, it saves energy, and can quickly position the silicon steel sheet, saving the positioning time and improving the positioning efficiency.

[0071] If the placement position of the silicon steel sheet is too skewed, and when the transverse positioning member 42 and the longitudinal positioning member 43 move successively, it is easy for the transverse positioning member 42 not to contact the silicon steel sheet. At this time, when the longitudinal positioning member 43 pushes the silicon steel sheet again, it is easy to generate excessive friction between the tip of the silicon steel sheet and the transverse positioning member 42, thereby damaging the silicon steel sheet. Therefore, when the transverse positioning member 42 and the longitudinal positioning member 43 move simultaneously, the above problems can also be avoided, improving the stacking quality of the silicon steel sheet and the safety of the equipment.

[0072] It should be noted that one end of the longitudinal positioning member 43 abutting against the silicon steel sheet is positioned as the abutting end, the middle of which is rotatably arranged on the base 41 , and the other end of the longitudinal positioning member 43 is defined as the hinged end and is hinged to the connecting rod 45 .

[0073] In some embodiments, the longitudinal positioning member 43 may be Figure 4 See the structure shown. Figure 4 , the longitudinal positioning member 43 is a V-shaped rod.

[0074] Compared with the straight rod, when the longitudinal positioning member 43 is not working, the position of the abutting end of the angled V-rod and the silicon steel sheet is relatively far away from the feeding mechanism 2, which can avoid affecting the normal operation of the feeding mechanism 2, expand the working space of the feeding mechanism 2, and ensure that the positioning mechanism 4 and the feeding mechanism 2 do not interfere with each other during operation.

[0075] In some embodiments, the positioning mechanism 4 can be used as follows: Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3 The positioning mechanism 4 also includes a first positioning block 46 and a second positioning block 47 .

[0076] The first positioning block 46 is arranged at one end of the transverse positioning piece 42, and is used to abut against the tip of the silicon steel sheet; the second positioning block 47 is arranged at one end of the longitudinal positioning piece 43, and is used to abut against the outer side wall of the silicon steel sheet; wherein the first positioning block 46 has a V-shaped tip positioning surface 461, and the tip positioning surface 461 is used to abut against the tip of the silicon steel sheet; the second positioning block 47 has a stepped side positioning surface 471, and the side positioning surface 471 is used to abut against the outer side wall of the silicon steel sheet.

[0077] Specifically, the two surfaces of the tip positioning surface 461 are connected by arc surfaces to avoid damaging the tip of the silicon steel sheet.

[0078] The tip of the silicon steel sheet can extend into the V-shaped tip positioning surface 461 and abut against the tip positioning surface 461, reducing the breakage rate of the silicon steel sheet tip. The stepped side positioning surface 471 cooperates with the stepped abutting surface 311 to accurately position the stacked silicon steel sheets in the width direction, thereby improving the neatness of the stacked core columns and rails.

[0079] In some embodiments, the transformer core assembly tool can be used as follows: Figures 4 to 5 See the structure shown. Figures 4 to 5 The transformer core assembly tool further includes a vibration component 5 , and the vibration component 5 includes a vibration block 51 .

[0080] The vibration block 51 is slidably disposed on the longitudinal positioning member 43 , has elastic freedom along the tangential direction of the longitudinal positioning member 43 , and is used for abutting against the second positioning block 47 .

[0081] When the second positioning block 47 abuts against the outer wall of the silicon steel sheet, the vibration block 51 knocks the second positioning block 47, causing the second positioning block 47 to vibrate, further positioning the stacked silicon steel sheets, and improving the neatness of the stacked silicon steel sheets. Moreover, the silicon steel sheets become relatively loose after vibration, reducing the friction between the silicon steel sheets, making it easier for the positioning assembly to position them, and improving the quality and stacking efficiency of the stacked core columns and rails.

[0082] In some embodiments, the vibration mechanism may be used as follows: Figures 4 to 5 See the structure shown. Figures 4 to 5 A slide groove 431 is provided on the longitudinal positioning member 43 , and the vibration block 51 is slidably arranged in the slide groove 431 ; the vibration assembly 5 also includes a flexible block 53 and two groups of elastic members 52 .

[0083] Two groups of elastic members 52 are disposed in the slide groove 431 , and the vibration block 51 is located between the two groups of elastic members 52 ; the flexible block 53 is disposed on the vibration block 51 and abuts against the second positioning block 47 .

[0084] Specifically, the flexible block 53 is made of rubber, and the elastic member 52 is a spring. The two groups of elastic members 52 are arranged in the slide groove 431, and the vibration block 51 is located between the two groups of elastic members 52 and in the middle of the slide groove 431. When the vibration assembly 5 is not working, the vibration block 51 squeezes the two groups of elastic members 52, so that the two groups of elastic members 52 have the same elastic potential energy.

[0085] When the longitudinal positioning member 43 rotates, the vibration block 51 slides toward the second positioning block 47 under the action of inertia, and the flexible block 53 located between the second positioning block 47 and the vibration block 51 abuts against the second positioning block 47. Since the rotation time of the longitudinal positioning member 43 is short, when the second positioning block 47 abuts against the outer wall of the silicon steel sheet, the flexible block 53 abuts against the second positioning block 47 for the first time, and then under the elastic force of the elastic member 52 close to the second positioning block 47, the vibration block 51 moves away from the second positioning block 47 and squeezes the other elastic member 52. After the other elastic member 52 is compressed to a certain extent, it pushes the vibration block 51 toward the second positioning block 47 again, thereby performing a reciprocating motion to achieve the effect of knocking the second positioning block 47.

[0086] When the longitudinal positioning member 43 rotates, the vibration assembly can be triggered to work, so that the vibration assembly and the positioning mechanism 4 can work synchronously, thereby improving work efficiency and saving energy.

[0087] In some embodiments, the feeding mechanism 2 can be used as follows: Figure 6 See the structure shown. Figure 6The feeding mechanism 2 includes a mechanical arm 21, a suction plate 22 and a suction nozzle 23.

[0088] The mechanical arm 21 is arranged on the outer side wall of the turntable 1 ; the suction plate 22 is arranged at the movable end of the mechanical arm 21 , and a plurality of suction nozzles 23 are arranged on the suction plate 22 , and the plurality of suction nozzles 23 are used to suck the silicon steel sheets.

[0089] Since the manufacturing process of each transformer core is the same, the order of the five groups of silicon steel sheets on the material preparation table sucked by the suction nozzle 23 is the same each time it works. During operation, the mechanical arm 21 moves toward the material preparation table and moves to the corresponding silicon steel sheets in turn. The suction nozzle 23 sucks the corresponding silicon steel sheets and cooperates with the mechanical arm 21 to place the silicon steel sheets on the corresponding core column bearing part 12 and rail bearing part 11. Multiple suction nozzles 23 can stably absorb the silicon steel sheets on the suction plate 22, improving the stability of the silicon steel sheets during transfer.

[0090] In some embodiments, the transformer core assembly tool further includes an air supply source, and the plurality of suction nozzles 23 are respectively connected to the air supply source.

[0091] Before the suction nozzle 23 sucks the silicon steel sheet, the air supply source can provide an air source for the suction nozzle 23, so that the suction nozzle 23 blows air outward to clean the dust on the surface of the silicon steel sheet, and prevent the suction nozzle 23 from sucking away the dust on the surface of the silicon steel sheet when sucking the silicon steel sheet. After the clean silicon steel sheets are stacked, the connection accuracy of the silicon steel sheets in the stacked state is improved. The suction nozzle 23 is also connected to a vacuum pump to provide suction for the suction nozzle 23 to suck the silicon steel sheet. In order to prevent the drawings from being disordered, the vacuum pump and the air supply source are not drawn in the figure.

[0092] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
