[0032] It should be noted that, without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other. The following will describe the present utility model in detail with reference to the drawings and in conjunction with the embodiments.

[0033] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0034] It should be noted that the terms "first", "second", etc. in the description and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances for the embodiments of the present utility model described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0035] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0036] It should be noted that for the production of a triangular transformer core, when the bending machine discharges materials, the width of the iron sheet is actually getting smaller and smaller, that is, the width of the latter iron sheet is smaller than that of the former iron sheet. And for each iron sheet, the width of the end portion output first by the bending machine (hereinafter referred to as the first end portion) is greater than the width of the end portion output later by the bending machine (hereinafter referred to as the second end portion). When stacking the iron sheets, it is necessary to ensure that the first end portion of each iron sheet is on the same side of the assembly, and the second end portion of each iron sheet is on the same side of the assembly, that is, each iron sheet has a definite directionality when stacked. However, since the posture of the iron sheet is not controlled after being output by the bending machine, it is impossible to ensure that the iron sheet is picked up and stacked in the correct direction. Therefore, the automatic picking of the lower half-frame iron sheets has not been realized.

[0037] In order to solve the above problems, as Figure 3 shown, the blanking device for the lower half-frame iron sheet of the triangular transformer core in this embodiment includes: an inclined table 225 and a support table 21. Among them, the inclined table 225 has an inclined surface 221 with a predetermined angle with the horizontal plane, and the lower half-frame iron sheet 4 gradually contacts the inclined surface 221 from one end to the other end so that the inclined surface 221 rotates relative to the horizontal plane along a preset direction; the support table 21 is arranged on the side close to the bottom of the inclined surface 221, and the lower half-frame iron sheet 4 slides from the inclined surface 221 to the support surface of the support table 21.

[0038] Applying the technical solution of this embodiment, as the lower half-frame iron sheet 4 is gradually output from the discharge port of the bending machine, the free end of the lower half-frame iron sheet 4 first falls on the high position of the inclined surface 221 close to the discharge port. With the continuous output of the discharge port, the first frame edge 6, the connecting edge 7, and the second frame edge 6 of the lower half-frame iron sheet 4 gradually fall onto the inclined surface 221. When the lower half-frame iron sheet 4 completely falls onto the inclined surface 221, the lower half-frame iron sheet 4 gradually slides towards the support table 21 under the guidance of the inclined surface 221 until the lower half-frame iron sheet 4 stops on the support table 21. The above structure enables each lower half-frame iron sheet 4 output from the bending machine to rotate along a predetermined direction under the guiding action of the inclined table 225, so that the wide (narrow) end of each lower half-frame iron sheet 4 is located on the same side of the support table 21. In this way, it is ensured that the iron sheets can be picked up and stacked in the correct direction each time. Therefore, the automatic picking of the lower half-frame iron sheets can be realized, improving the efficiency of the triangular transformer core during material collection.

[0039] As Figure 3 and Figure 5 shown, in this embodiment, the inclination angle of the inclined surface 221 is a preset angle. Of course, in other embodiments not shown in the figure, the inclination angle of the inclined surface 221 can also be adjusted on-site according to the actual situation. That is, the inclined table 225 further includes an angle adjustment mechanism, and the angle adjustment mechanism can adjust the inclination angle of the inclined surface 221.

[0040] As Figure 3 、 Figure 7 and Figure 8As shown, in this embodiment, the blanking device also includes: a stop mechanism 229, the stop mechanism 229 includes a movably arranged baffle 223 and a driving mechanism 224, the baffle 223 has a stop position for stopping at the middle of the inclined surface 221 and a avoidance position for avoiding the lower half frame iron sheet 4 on the inclined surface 221, and the driving mechanism 224 drives the baffle 223 to switch between the stop position and the avoidance position to perform secondary posture adjustment. The above-mentioned baffle 223 has two functions: first, when there is a lower half-frame iron sheet 4 on the support table 21, the baffle 223 is located at the stop position, so that the next lower half-frame iron sheet 4 output from the discharge port 11 can be blocked at the baffle 223, while improving the production efficiency, ensuring that only one lower half-frame iron sheet 4 enters the support table 21 at a time, which is convenient for subsequent automated clamping; second, before the lower half-frame iron sheet 4 is cut off by the bending machine 10, the baffle 223 is located at the stop position, and the baffle 223 also plays a certain buffering and transition role, so that after the baffle 223 is opened, the lower half-frame iron sheet 4 can gradually slide onto the support table 21 in a predetermined posture, which is convenient for subsequent clamping.

[0041] like Figure 3 , Figure 7 and Figure 8 As shown, in this embodiment, the stop mechanism 229 further includes: a transmission member 2291, the baffle 223 is pivotally arranged through a rotating shaft, the transmission member 2291 includes a first transmission rod 2292 and a second transmission rod 2293 arranged at an angle, the first transmission rod 2292 is connected to the baffle 223, and the driving mechanism 224 is a cylinder, and the cylinder pushes the second transmission rod 2293 so that the first transmission rod 2292 drives the baffle 223 to rotate. The above structure is simple and easy to implement.

[0042] In this embodiment, the blanking device further includes: a control device 70 and a baffle sensor. The drive mechanism 224 is electrically connected to the control device 70. The baffle sensor is electrically connected to the control device 70, and the control device 70 controls the drive mechanism 224 to operate according to the detection signal of the baffle sensor, so that the baffle 223 switches its position. The above structure can improve the automation level of the equipment, thereby improving the subsequent material collection efficiency.

[0043] like Figures 3 to 5As shown, in this embodiment, the blanking device further includes a pushing structure 222. The pushing structure 222 has a pushing head movably arranged above the support table 21, and the pushing head pushes the lower half-frame iron sheet 4 towards the middle of the support table 21 for attitude adjustment. Specifically, after the lower half-frame iron sheet 4 slides down to the support table 21, the pushing structure 222 moves the lower half-frame iron sheet 4 away from the edge of the support table 21. The pushing structure 222 is equivalent to having a secondary attitude adjustment effect on the lower half-frame iron sheet 4, enabling each lower half-frame iron sheet 4 to stay within a predetermined range of the support table 21 in a predetermined attitude, providing conditions for subsequent automatic material collection, and thus improving the efficiency of collecting triangular transformer cores.

[0044] As Figures 3 to 5 shown, in this embodiment, the pushing structure 222 includes at least one of a first pushing head 226, a second pushing head 227, and a third pushing head 228 that move horizontally. The first pushing head 226 and the second pushing head 227 are arranged on opposite sides in the first direction n of the support table 21, and the third pushing head 228 is arranged on one side of the support table 21 in the second direction m perpendicular to the first direction n. The first direction n is the direction in which the lower half-frame iron sheet 4 slides down. Specifically, the first pushing head 226 and the second pushing head 227 make the lower half-frame iron sheet 4 stay in the middle of the support table 21 in the first direction n, and the third pushing head 228 makes the lower half-frame iron sheet 4 stay in the middle of the support table 21 in the second direction m. Of course, in other embodiments not shown in the figure, the pushing structure 222 may include any one or any two of the first pushing head 226, the second pushing head 227, and the third pushing head 228.

[0045] As Figures 3 to 5 shown, in this embodiment, an avoidance hole 2211 for avoiding the second pushing head 227 is provided at the bottom of the inclined slope 221. Specifically, when the lower half-frame iron sheet 4 slides down from the inclined slope 221, the second pushing head 227 retracts to avoid the second pushing head 227 interfering with the attitude of the lower half-frame iron sheet 4 when it slides down. When the lower half-frame iron sheet 4 lands on the support table 21, the second pushing head 227 extends again to push the lower half-frame iron sheet 4.

[0046] As Figure 6 shown, in this embodiment, the blanking device further includes a support table sensor. The pushing structure 222 is electrically connected to the control device 70; the support table sensor is electrically connected to the control device 70 to detect whether there is a lower half-frame iron sheet 4 on the support table 21, and the control device 70 controls the action of the pushing structure 222 according to the detection signal of the support table sensor. The above structure can improve the automation level of the equipment, thereby improving the subsequent material collection efficiency.

[0047] As Figures 6 to 9As shown in the figure, the present application also provides an automatic material collecting device for the lower half frame of a triangular transformer core. The embodiment of the automatic material collecting device according to the present application includes: a bending machine 10, a blanking device 20, a first picking device 60, and a lower half frame material collecting assembly 50. Among them, the bending machine 10 has a discharge port 11 for outputting the lower half frame iron sheet 4; the blanking device 20 is the blanking device 20 for the lower half frame iron sheet of the triangular transformer core described above, and the inclined slope 221 of the blanking device 20 is located directly below the discharge port 11; the first picking device 60 picks up the lower half frame iron sheet 4 on the support table 21 of the blanking device 20; the lower half frame material collecting assembly 50 has a first storage platform 51 for storing the lower half frame iron sheet 4. Since the above-mentioned blanking device 20 has the function of enabling each lower half frame iron sheet 4 to stay within a predetermined range on the support table 21 in a predetermined posture, the first picking device 60 can accurately pick up each lower half frame iron sheet 4 and accurately stack each lower half frame iron sheet 4 on the lower half frame material collecting assembly 50, realizing fully automatic material collection and improving the efficiency of collecting the triangular transformer core during material collection.

[0048] Preferably, in this embodiment, the automatic material collecting device for the lower half frame of the triangular transformer core further includes a vision module 80. The vision module 80 is electrically connected to the control device 70. The vision module 80 can send the specific position information of the lower half frame iron sheet 4 to the control device, and the control device then controls the first picking device 60 to act accurately according to this position information.

[0049] As Figure 3 、 Figures 6 to 9 shown in the figure, in this embodiment, the bending machine 10 is electrically connected to the control device 70 of the blanking device 20, and the control device 70 controls the bending machine 10 to act according to the detection signal of the baffle sensor of the blanking device 20. Specifically, when the baffle sensor detects that there is a lower half frame iron sheet 4 on the baffle 223, the control device will cause the bending machine 10 to stop producing the lower half frame iron sheet 4. The above structure ensures that there is only one lower half frame iron sheet 4 at the baffle 223, avoiding the accumulation of multiple lower half frame iron sheets 4 at the baffle 223, so as not to affect the subsequent picking of the lower half frame iron sheet 4.

[0050] As Figure 6 and Figure 9 shown in the figure, the present application also provides an automatic material collecting device for a triangular transformer core. The embodiment of the automatic material collecting device for the triangular transformer core according to the present application includes: an automatic material collecting device for the lower half frame and an automatic material collecting device for the upper half frame. Among them, the automatic material collecting device for the lower half frame is the above-mentioned automatic material collecting device; the automatic material collecting device for the upper half frame includes a second picking device 40 for picking up the upper half frame iron sheet at the discharge port 11 of the automatic material collecting device for the lower half frame and a second storage platform 31 for storing the upper half frame iron sheet. The above structure enables the triangular transformer core to realize fully automatic material collection, thereby improving the material collection efficiency of the triangular transformer core.
