Description

Technical Field

[0001] This invention relates to the technical field of motor stator production, and more particularly to an automatic silicon steel sheet embedding machine. Background Technology

[0002] As is well known, the production of motor stators involves injection molding an insulator onto silicon steel sheets to form an integral structure with the silicon steel sheets for winding. Therefore, the production of motor stators is inseparable from the use of injection molds and injection molding machines.

[0003] Currently, the insertion of silicon steel sheets into the cavity of injection molds and the removal of molded products from the injection molds are all done manually by operators, which results in low efficiency and the insertion accuracy being affected by the operator's experience.

[0004] Therefore, there is an urgent need for an automatic silicon steel sheet burial machine to overcome one or more of the above-mentioned defects. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic silicon steel sheet embedding and retrieval machine with high embedding and retrieval efficiency, embedding accuracy unaffected by operator experience, and high embedding reliability.

[0006] To achieve the above objectives, the automatic silicon steel sheet embedding machine of the present invention is suitable for embedding silicon steel sheets into an injection mold and removing the molded product with castable solidified material formed by the injection mold. The injection mold includes a lower mold mounted on the injection molding machine base and switchable between an open / closed position and a loading / unloading position; an upper mold capable of opening and closing with the lower mold in the open / closed position; and an opening / closing actuator located above the upper mold and mounted on the injection molding machine base. The opening / closing actuator is assembled and connected to the upper mold. The automatic silicon steel sheet embedding machine of the present invention includes an upper and lower transfer frame arranged directly above the lower mold at the loading and unloading position and sliding up and down on the injection molding machine platform; an upper and lower transfer driver for driving the upper and lower transfer frame to move closer to or away from the lower mold in the vertical direction; a loading positioning seat assembled on the upper and lower transfer frame and protruding downward from the upper and lower transfer frame; a discharge rack for stacking silicon steel sheets and located beside the loading positioning seat; a transfer mechanism for the silicon steel sheets discharged by the discharge rack to slide downward and transfer the slid-in silicon steel sheets to the loading positioning seat; an ejection and embedding mechanism assembled on the upper and lower transfer frame for ejecting the silicon steel sheets from the loading positioning seat and embedding them into the lower mold at the loading and unloading position; and a removal robot for removing the molded product from the lower mold at the loading and unloading position. The removal robot is located beside the upper and lower transfer frame, and the discharge rack and the transfer mechanism are each assembled on the upper and lower transfer frame.

[0007] Compared with existing technologies, this new technology utilizes a combination of "upper and lower transfer frames, upper and lower transfer drivers, loading positioning seats, unloading frames, transfer mechanisms, ejection and embedding mechanisms, and a retrieval robot." When embedding silicon steel sheets into the lower mold, the lower mold switches to the loading / unloading position. The upper and lower transfer drivers then drive the upper and lower transfer frames to move closer to the lower mold in the loading / unloading position until the loading positioning seat is in contact with the lower mold, ensuring alignment. At this point, the transfer mechanism moves the silicon steel sheets sliding down from the unloading frame to the loading positioning seat. The ejection and embedding mechanism then ejects the silicon steel sheets from the loading positioning seat downwards and embeds them into the lower mold in the loading / unloading position. This improves the efficiency of silicon steel sheet embedding and ensures its reliability, unaffected by operator experience. Furthermore, the retrieval robot allows for the removal of the molded parts from the lower mold in the loading / unloading position, further improving retrieval efficiency. Furthermore, since the loading positioning seat, the discharge rack, the transfer mechanism, and the ejection and embedding mechanism move closer to or further away from the lower mold in the loading and unloading position along with the upper and lower transfer frames, the automatic silicon steel sheet embedding machine of the present invention is more compactly matched with the injection molding machine.

[0033] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0034] Please see Figure 1 and Figure 2 The automatic silicon steel sheet embedding machine 100 of the present invention is used to handle the loading and unloading operations of the injection mold 300. For example, the automatic silicon steel sheet embedding machine 100 of the present invention is used to... Figure 15 The circular silicon steel sheet 210 shown is embedded in the injection mold 300. It is also used to remove the molded product 200, obtained by casting the insulator 230 from the silicon steel sheet 210 in the injection mold 300, from the injection mold 300, thereby realizing the automatic loading and unloading operation of the silicon steel sheet automatic embedding machine 100 of the present invention. Therefore, the silicon steel sheet automatic embedding machine 100 of the present invention is configured on the injection molding machine table 400 to be responsible for the loading and unloading operation of the injection mold 300.

[0035] Combined Figure 1 and Figure 2 The injection mold 300 includes a lower mold 310 mounted on an injection molding machine 400 and switchable between an opening / closing position and a loading / unloading position; an upper mold 320 that engages with the lower mold 310 in the opening / closing position; and an opening / closing actuator 330 located above the upper mold 320 and mounted on the injection molding machine 400. The opening / closing actuator 330 is connected to the upper mold 320 to meet the need for the upper mold 320 to move vertically by being driven by the opening / closing actuator 330. Optionally, as an example, the opening / closing actuator 330 can be a hydraulic cylinder. Obviously, depending on actual needs, the opening / closing actuator 330 can also be a pneumatic cylinder, etc., and is not limited thereto. Figure 2 In this example, the lower mold 310 is slidably mounted on the injection molding machine 400, allowing it to switch between the mold opening / closing position and the loading / unloading position by sliding. Obviously, depending on actual needs, the lower mold 310 can also switch between the mold opening / closing position and the loading / unloading position by rotating. Therefore, it is not considered... Figure 2 The above is for reference only. It should be noted that... Figure 2 In the diagram, the lower mold 310, indicated by the dashed line, is located at the mold opening and closing position, while the lower mold 310, indicated by the solid line, is located at the material loading and unloading position.

[0036] And combined Figure 3 and Figure 4As an example, the automatic silicon steel sheet embedding machine 100 of the present invention includes an upper and lower transfer frame 10, an upper and lower transfer driver 20, a feeding positioning seat 30, a discharging frame 40, a transfer mechanism 50, an ejection embedding mechanism 60a, and a take-up robot 60b. The upper and lower transfer frame 10 is arranged directly above the lower mold 310 in the feeding and unloading position, and the upper and lower transfer frame 10 is also slidably mounted on the injection molding machine base 400 (see...). Figure 1 As shown), to meet the need for the upper and lower transfer frame 10 to slide up and down relative to the injection molding machine table 400. The upper and lower transfer driver 20 is used to drive the upper and lower transfer frame 10 to move closer to or away from the lower mold 310 (referring to the lower mold 310 in the loading and unloading position) in the vertical direction; alternatively, as an example, the upper and lower transfer driver 20 is a hydraulic cylinder. Obviously, depending on the actual needs, the upper and lower transfer driver 20 can also be a pneumatic cylinder, etc., so it is not limited to this description.

[0037] The loading positioning seat 30 is assembled on the upper and lower transfer frame 10 to meet the need for the loading positioning seat 30 to move up and down together with the upper and lower transfer frame 10; the loading positioning seat 30 also protrudes downward from the upper and lower transfer frame 10 to meet the need for the loading positioning seat 30 to be in close contact with the lower mold 310 when it is approaching the lower mold 310 in the loading and unloading position.

[0038] The material rack 40 is used for stacking silicon steel sheets 210 in layers. The material rack 40 is assembled to the upper and lower transfer frame 10 to allow the material rack 40 to move up and down together with the upper and lower transfer frame 10. The material rack 40 is also located beside the loading positioning seat 30, for example, in... Figure 4 In the middle, the left-side material rack 40 is located to the left of the material loading positioning seat 30, and the right-side material rack 40 is located to the right of the material loading positioning seat 30; optionally, in Figure 3 As an example, the material rack 40 can accommodate silicon steel sheets 210 stacked in four rows; obviously, depending on actual needs, the material rack 40 can also accommodate silicon steel sheets 210 stacked in one, two, three, or five rows, so it is not limited to this. Figure 3 The above is the limit.

[0039] The transfer mechanism 50 is assembled on the upper and lower transfer frame 10 to meet the need for the transfer mechanism 50 to move up and down together with the upper and lower transfer frame 10; the silicon steel sheet 210 discharged by the discharge frame 40 slides down into the transfer mechanism 50 to receive the silicon steel sheet 210 sliding down from the discharge frame 40, and transfer the slid-in silicon steel sheet 210 to the loading positioning seat 30, so as to prepare for the silicon steel sheet 210 on the loading positioning seat 30 to be embedded into the lower mold 310 in the loading and unloading position.

[0040] The ejection and embedding mechanism 60a is assembled on the upper and lower transfer frame 10 to meet the need for the ejection and embedding mechanism 60a to move up and down together with the upper and lower transfer frame 10; the ejection and embedding mechanism 60a is also used to eject the silicon steel sheet 310 of the loading positioning seat 30 and embed it into the lower mold 310 in the loading and unloading position to meet the need for the embedded silicon steel sheet 310 to switch to the mold opening and closing position together with the lower mold 310 and cooperate with the upper mold 320 in mold closing.

[0041] The robotic arm 60b is used to remove the molded part 200 (see figure) from the lower mold 310, which is in the loading / unloading position. Figure 16 The robotic arm 60b is located beside the upper and lower transfer frame 10; alternatively, it can be used to retrieve the robotic arm 60b. Figure 1 In the example shown, the robotic arm 60b is mounted on the injection molding machine base 400, which provides the mounting location and support for the robotic arm 60b. Obviously, depending on actual needs, the robotic arm 60b can also be directly fixed to the ground; therefore, it is not considered... Figure 1 As shown, this is a limited description. Specifically, at... Figure 1 As an example, the automatic silicon steel sheet embedding machine 100 of the present invention also includes a cavity-dividing mold base 70, a storage rack 80, and an auxiliary robot arm 90; the cavity-dividing mold base 70 is located beside the injection molding machine table 400, for example, but not limited to Figure 1 To the right of the image shown, the cavity-dividing mold base 70 is also located above the storage rack 80. The cavity-dividing mold base 70 has multiple cavity-dividing channels 71 arranged in a matrix in the horizontal direction, and a number of cavity-dividing delivery pipes 72 equal to the number of cavity-dividing channels 71. Each cavity-dividing delivery pipe 72 is assembled onto the cavity-dividing mold base 70 from below, as shown in the image. Figure 10 and Figure 12 As shown; each cavity delivery pipe 72 is also connected to a corresponding cavity channel 71 to meet the requirement that the molded part 200 entering through each cavity channel 71 can slide downward along the corresponding cavity delivery pipe 72. Each cavity delivery pipe 72 also extends downward to connect with an inlet 81 (see 12) opened by the storage rack 80, the same number as the cavity channels 71. That is to say, the inlets 81 are opened by the storage rack 80, and the number of inlets 81 is the same as the number of cavity channels 71. The storage rack 80 is located on the side of the injection molding machine 400, for example, but not limited to Figure 1 To the right of the image shown, the storage rack 80 also contains the same number of storage boxes 82 as the cavity channels 71, with each storage box 82 located below a corresponding inlet 81; the auxiliary robot 90 is used to cooperate with the take-up robot 60b to pull off and remove the casting solidified material 220 on the molded product 200 held by the take-up robot 60b, the casting solidified material 220 being visible. Figure 13 and Figure 14As shown. Therefore, with the help of the auxiliary robot arm 90, the casting solidified material 220 is pulled off and transferred from the molded article 200, so that the molded article 200 with the casting solidified material 220 removed can be divided into cavities by the cavity dividing mold base 70, and the molded article 200 after being divided into cavities can enter the corresponding storage box 82 for storage along the cavity dividing conveying pipe 72. More specifically, see the description below.

[0042] Combination Figure 1 , Figure 3 and Figure 4 As an example, the upper and lower transfer frame 10 includes a lower horizontal plate 11, an intermediate horizontal plate 12 located directly above the middle portion 11a of the lower horizontal plate 11, an upper horizontal plate 13 located directly above the intermediate horizontal plate 12, a first upper and lower support column 14 supported between the intermediate horizontal plate 12 and the lower horizontal plate 11, and a second upper and lower support column 15 supported between the intermediate horizontal plate 12 and the upper horizontal plate 13. Alternatively, as an example, the first upper and lower support columns 14 are respectively arranged at the four corners of both the intermediate horizontal plate 12 and the lower horizontal plate 11, and the second upper and lower support columns 15 are respectively arranged at the four corners of both the intermediate horizontal plate 12 and the upper horizontal plate 13. The loading positioning seat 30 is assembled to the middle portion 11a of the lower horizontal plate 11 and protrudes downward from the middle portion 11a to more effectively ensure the uniform and reliable force uniformity between the loading positioning seat 30 and the lower mold 310 in the loading / unloading position. The ejector insertion mechanism 60a is mounted on the intermediate horizontal plate 12, which provides a mounting location and support for the ejector insertion mechanism 60a. The ejector insertion mechanism 60a is laterally surrounded by the first upper and lower support columns 14 and the second upper and lower support columns 15, resulting in a more compact arrangement between the ejector insertion mechanism 60a and the upper and lower transfer frames 10. The upper and lower transfer actuator 20 is located directly above the upper horizontal plate 13. This design allows the upper and lower transfer actuator 20 to avoid interference with the lower mold 310 while maintaining a more compact arrangement with the upper and lower transfer frames 10. The upper and lower transfer actuator 20 is also mounted on the injection molding machine 400, which provides support for the upper and lower transfer actuator 20. The output end 21 of the upper and lower transfer actuator 20 is arranged downwards and connected to the upper horizontal plate 13, simplifying the assembly relationship between the upper and lower transfer actuator 20 and the upper horizontal plate 13. The material rack 40 is located next to the upper horizontal plate 13 and the middle horizontal plate 12 on the same side. The material rack 40 is mounted on the upper horizontal plate 13 and is also suspended downwards above the transfer mechanism 50. Optionally, it is located on the upper horizontal plate 13. Figure 3 In this example, the material rack 40 is fixed to the upper horizontal plate 13 by means of a portal frame bracket 41, so that the material rack 40 is suspended from the side of the upper horizontal plate 13, thereby effectively increasing the number of silicon steel sheets 210 that can be stacked vertically on the material rack 40; furthermore, in Figure 3 and Figure 4In this example, the material rack 40 and the transfer mechanism 50 are arranged opposite each other with the intermediate horizontal plate 12 as the center. This design can multiply the number of silicon steel sheets 210 that can be stacked vertically, as well as the number of silicon steel sheets 210 that can be transferred to the loading positioning seat 30. Obviously, the arrangement of the material rack 40 and the transfer mechanism 50 can be other than that required by actual needs, so it is not specified here. Figure 3 and Figure 4 The above is for reference only. Specifically, in conjunction with... Figures 3 to 5 As an example, the upper and lower transfer frame 10 also includes a positioning guide seat 16 located beside the ejection and embedding mechanism 60a. The positioning guide seat 16 is mounted on the lower horizontal plate 11 and corresponds to the discharge frame 40 in the vertical direction. The positioning guide seat 16 has a positioning guide channel 161 for positioning the silicon steel sheet 210 discharged by the discharge frame 40 in the circumferential direction and sliding downward. The discharge frame 40 is partially placed in the positioning guide channel 161 to effectively ensure that the silicon steel sheet 210 discharged by the discharge frame 40 reliably slides into the transfer mechanism 50 under its own weight and under the positioning and guiding action of the positioning guide channel 161. The transfer mechanism 50 performs transfer movement below the positioning guide seat 16, for example, at... Figure 5 In this design, the positioning guide seat 16 has a clearance space 162 to allow the transfer mechanism 50 to move. The clearance space 162 extends along the length of the positioning guide seat 16 and penetrates downward through it, so that the clearance space 162 is aligned with the transfer mechanism 50 when the positioning guide seat 16 is mounted on the lower horizontal plate 11. More specifically, the side of the positioning guide channel 161 facing the transfer mechanism 50 is an open side 1611, which facilitates the operator to perform circumferential adjustment of the silicon steel sheet 210 before it enters the positioning guide channel 161. It should be noted that when there are two material racks 40 and two transfer mechanisms 50, there are also two positioning guide seats 16, so that one positioning guide seat 16 corresponds to one material rack 40 and one transfer mechanism 50.

[0043] Combination Figure 3 , Figure 4 and Figure 7As an example, the transfer mechanism 50 includes a linear actuator 51 and a transfer seat 52. The linear actuator 51 is mounted on a lower horizontal plate 11, which provides support for the linear actuator 51. The transfer seat 52 slides on the lower horizontal plate 11 below the positioning guide seat 16, and the transfer seat 52 has a receiving channel 521 for the silicon steel sheet 200 to slide downwards. Therefore, when the linear actuator 51 drives the receiving channel 521 of the transfer seat 52 to align with the positioning guide channel 161 in the vertical direction, the silicon steel sheet 210 in the positioning guide channel 161 can slide downwards. The silicon steel sheet 210 slides into the receiving channel 521 of the transfer seat 52. When the linear actuator 51 drives the receiving channel 521 of the transfer seat 52 to be misaligned with the positioning guide channel 161 in the vertical direction, the silicon steel sheet 210 in the positioning guide channel 161 cannot slide down into the transfer seat 52. That is, the transfer seat 52 at this time blocks the silicon steel sheet 210 in the positioning guide channel 161 from sliding down into the transfer seat 52. Therefore, the transfer mechanism 50 transfers the silicon steel sheet 210 to the loading positioning seat 30 in an orderly manner. Specifically, as an example, the linear actuator 51 can be a cylinder or a hydraulic cylinder, so that the linear actuator 51 can quickly drive the receiving channel 521 of the transfer seat 52 to slide to a position aligned with the positioning guide channel 161, or to slide to the loading positioning channel 31 of the loading positioning seat 30 (see Figure 6 The alignment position improves the transfer efficiency of the silicon steel sheet 210.

[0044] Combination Figure 1 , Figure 4 and Figure 6 As an example, the ejector-embedded mechanism 60a includes an ejector-embedded actuator 61 and an ejector-embedded mold core 62. The ejector-embedded actuator 61 is mounted on an intermediate horizontal plate 12, which is supported by the intermediate horizontal plate 13. The output end 611 of the ejector-embedded actuator 61 passes downward through the intermediate horizontal plate 12 and is connected to the ejector-embedded mold core 62 to meet the need for the ejector-embedded mold core 62 to move up and down driven by the ejector-embedded actuator 61. At this time, the loading positioning seat 30 is provided with a loading positioning channel 31 for the silicon steel sheet 210 ejected from the transfer mechanism 50 by the ejector-embedded mechanism 60a to pass through and be positioned, so as to ensure that the silicon steel sheet 210 passes downward through the loading positioning channel 31 and is accurately embedded in the lower mold 310 in the loading / unloading position. For example, the ejector-embedded actuator 61 can be a cylinder or a hydraulic cylinder, but is not limited thereto.

[0045] like Figure 8 and Figure 9As shown, as an example, the lifting robot 60b includes a linear transfer module 63, a vertical drive 64 mounted on the linear transfer module 63, a cantilever 65 mounted on the vertical drive 64, and a clamping drive 66 mounted on the cantilever 65 at a position away from the vertical drive 64. A movable clamping block 67 is mounted at the output end of the clamping drive 66, and a fixed clamping block 68 correspondingly cooperates with the movable clamping block 67 on the cantilever 65. Therefore, the clamping operation of the molded product 200 is realized through the cooperation of the fixed clamping block 68 and the movable clamping block 67 driven by the clamping drive 66; furthermore, the clamping operation of the movable clamping block 67 and the positioning block 68 on the molded product 200 is better ensured by the cooperation of the linear transfer module 63 and the vertical drive 64. For example, the vertical drive 64 and the clamping drive 66 can be cylinders or hydraulic cylinders, but are not limited thereto; furthermore, the linear transfer module 63 is well known in the art and will not be described in detail here.

[0046] like Figure 13 and Figure 14 As shown, as an example, the auxiliary robot 90 includes a horizontally rotating frame 91, a rotary drive mechanism 92 for driving the rotating frame 91 to rotate, a lifting frame 93 slidingly mounted on the rotating frame 91, a lifting actuator 94 mounted on the rotating frame 91 for driving the lifting frame 93 to move up and down, a telescopic actuator 95 mounted on the lifting frame 93, and a slurry clamping assembly 96 mounted on the telescopic actuator 95. Therefore, by means of the cooperation of the rotating frame 91 and the rotary drive mechanism 92, the auxiliary robot 90 can be responsible for gripping the casting slurry 220 of the injection molds 300 on the two injection molding machines 400. For example, the lifting actuator 94 and the telescopic actuator 95 can be cylinders or hydraulic cylinders, but are not limited thereto; furthermore, the slurry clamping assembly 96 can be a pneumatic gripper. Since the specific structure of the rotary drive mechanism 92 is well known in the art, it will not be described in detail here.

[0047] Compared with existing technologies, by utilizing the coordination of "upper and lower transfer frame 10, upper and lower transfer driver 20, loading positioning seat 30, unloading frame 40, transfer mechanism 50, ejection and embedding mechanism 60a, and removal robot 60b", when embedding silicon steel sheet 210 into lower mold 310, the lower mold 310 is switched to the loading and unloading position, as shown in the figure. Figure 2The lower mold 310, shown in solid line, is driven by the upper and lower transfer driver 20 to move closer to the lower mold 310 in the loading / unloading position until the loading positioning seat 30 is in close contact with the lower mold 310 in the loading / unloading position, ensuring that the loading positioning seat 30 and the lower mold 310 in the loading / unloading position are aligned. At this time, the transfer mechanism 50 transfers the silicon steel sheet 210 that slides down from the discharge frame 40 to the loading positioning seat 30. The ejection and embedding mechanism 60a ejects the silicon steel sheet 210 in the loading positioning seat 30 downward and embeds it into the lower mold 310 in the loading / unloading position, thereby improving the embedding efficiency of the silicon steel sheet 210 and ensuring the reliability of the embedding of the silicon steel sheet 210 and is not affected by the operator's experience. In addition, with the help of the take-up robot 60b, the molded product 200 in the lower mold 310 in the loading / unloading position can be taken away to improve the take-up efficiency. Furthermore, since the loading positioning seat 30, the unloading rack 40, the transfer mechanism 50 and the ejection and embedding mechanism 60a move closer to or further away from the lower mold 310 in the loading and unloading position as they follow the upper and lower transfer frame 10, it is ensured that the automatic silicon steel sheet embedding machine 100 of the present invention fits more closely with the injection molding machine table 400.

[0048] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
