Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, in particular to an opening and closing device and a winding machine. Background Art

[0002] In the current winding machines, since the thickness of the insulating skeleton is relatively thin, the wall surface of the insulating skeleton is easily expanded outward and broken during the winding process; therefore, it is necessary to first position the insulating skeleton on the skeleton mold, and then insert a skeleton pressing plate into the skeleton mold, and press the skeleton pressing plate against the upper end surface of the skeleton mold and the insulating skeleton, so that the skeleton mold and the skeleton pressing plate can provide positioning support for the insulating skeleton, ensuring that the insulating skeleton will not be squeezed when winding on the insulating skeleton.

[0003] When the winding is completed, the skeleton pressing plate needs to be separated from the skeleton mold first, and then the insulating skeleton can be removed from the skeleton mold; currently, the skeleton pressing plate is usually separated from the skeleton mold manually, which is time-consuming and labor-intensive, resulting in low separation efficiency, thereby affecting the efficiency of removing the insulating skeleton from the skeleton mold.

[0047] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0048] like Figures 1 to 4 As shown, in this embodiment, an opening and closing device and a winding machine including the opening and closing device are proposed, and the winding machine also includes a rotating table 40, a skeleton mold 30, a skeleton 10 and a skeleton pressing plate 20. The skeleton mold 30 is fixedly installed on the rotating table 40, and the skeleton 10 is positioned and sleeved on the skeleton mold 30. The skeleton pressing plate 20 is inserted into the skeleton mold 30, and the skeleton pressing plate 20 presses against the upper end surface of the skeleton mold 30 and the skeleton 10, so that the skeleton pressing plate 20 and the skeleton mold 30 can provide positioning support for the skeleton 10; and the rotating table 40 can drive the skeleton mold 30 to rotate, so as to drive the skeleton 10 on the skeleton mold 30 to rotate and wind. In this embodiment, the skeleton 10 is specifically an insulating skeleton.

[0049] It is worth noting that the focus of improvement in this embodiment is on the automatic opening and closing between the skeleton mold 30 and the skeleton pressure plate 20. The rotating table 40, the skeleton mold 30, the skeleton pressure plate 20, the skeleton 10 and other structures in the winding machine and the winding process are not described in detail here, and reference can be made to the existing winding machines.

[0050] Specifically, Figures 1 to 4As shown, the opening and closing device includes a frame 1 and an opening and closing component 2; wherein, the rotating table 40 is rotatably arranged on the frame 1 and is relatively located below the opening and closing component 2, that is, the opening and closing component 2 and the rotating table 40 are arranged vertically opposite to each other; the opening and closing component 2 is slidably installed to the frame 1 along the Z axis, and the opening and closing component 2 includes an opening and closing body 21 and a clamping jaw 22, and the clamping jaw 22 can be slidably connected to the opening and closing body 21 along the X axis or the Z axis; the opening and closing body 21 can release the connection between the skeleton pressing plate 20 and the skeleton mold 30, and the clamping jaw 22 can move to connect with the skeleton pressing plate 20 and drive the skeleton pressing plate 20 to separate from the skeleton mold 30.

[0051] Compared with the prior art, the opening and closing device in this embodiment changes the opening and closing method between the skeleton mold 30 and the skeleton pressure plate 20; by slidingly setting the opening and closing component 2 along the Z axis in the frame 1, the opening and closing component 2 can be moved downward along the Z axis to approach the skeleton pressure plate 20, so that the opening and closing body 21 in the opening and closing component 2 can release the connection between the skeleton pressure plate 20 and the skeleton mold 30; then the clamping jaws 22 in the opening and closing component 2 are moved along the X axis or the Z axis relative to the opening and closing body 21, so that the clamping jaws 22 can be moved to connect with the skeleton pressure plate 20, and the skeleton pressure plate 20 can be driven to separate from the skeleton mold 30 by the upward movement of the clamping jaws 22 along the Z axis, thereby realizing automatic disengagement and separation between the skeleton pressure plate 20 and the skeleton mold 30, which is conducive to the subsequent direct removal of the skeleton 10 from the skeleton mold 30; the whole process saves time and labor, can improve the separation work efficiency, and does not require manual participation, which can improve the work efficiency of removing the skeleton 10 from the skeleton mold 30.

[0052] That is, the opening and closing device in this embodiment first releases the connection between the skeleton pressing plate 20 and the skeleton mold 30, so that no connection structure is set between the skeleton pressing plate 20 and the skeleton mold 30; then the skeleton pressing plate 20 is moved upward along the Z-axis relative to the skeleton mold 30, so that the skeleton pressing plate 20 and the skeleton mold 30 can be automatically separated, thereby ensuring the smooth opening and closing separation; and, through the above-mentioned opening and closing device, the automatic plugging and abutting between the skeleton mold 30 and the skeleton pressing plate 20 can also be achieved. The disengagement and separation process between the skeleton mold 30 and the skeleton pressing plate 20 is described in detail below, and the plugging and abutting process can refer to the description of the separation process.

[0053] It is worth noting that the functions of the skeleton pressing plate 20 and the skeleton mold 30 in this embodiment are to limit the various surfaces of the skeleton 10 and leave only the surface for winding, so as to ensure that the skeleton 10 will not be damaged by the tension of the winding during the winding process, and the skeleton 10 can be well protected; and the skeleton pressing plate 20 automatically opens and closes in the skeleton mold 30 to load and unload materials and can self-lock and press the skeleton 10 to ensure the stability of the skeleton 10. Among them, the winding wire wound on the skeleton 10 can be a round copper wire.

[0054] Furthermore, if Figures 1 to 4 As shown, the opening and closing device also includes an adapter seat 3, an intermediate seat 5 and a first driving member 4; wherein the adapter seat 3 is slidably connected to the frame 1 along the Z axis, the intermediate seat 5 is fixedly connected to the adapter seat 3, and the opening and closing body 21 is connected to the intermediate seat 5; the fixed end of the first driving member 4 is connected to the frame 1, and the driving end of the first driving member 4 is connected to the adapter seat 3, and the first driving member 4 is used to drive the adapter seat 3, the intermediate seat 5 and the opening and closing assembly 2 thereon to move along the Z axis. In this embodiment, the first driving member 4 can specifically be a linear cylinder.

[0055] Specifically, Figure 1 As shown, a guide rail 11 is provided on one of the frame 1 and the adapter 3, and a guide block 31 is provided on the other, the guide rail 11 extends along the Z axis, and the guide block 31 can slide along the guide rail 11 along the Z axis, so as to provide guidance and reliability for the movement of the adapter 3 relative to the frame 1 on the Z axis. In this embodiment, the guide rail 11 is provided on the frame 1, and the guide block 31 is provided on the adapter 3. In other embodiments, the guide block 31 can also be provided on the frame 1, and the guide rail 11 can also be provided on the adapter 3, which is not specifically limited here.

[0056] Furthermore, if Figure 1 and Figure 2 As shown, a plurality of opening and closing components 2 are provided, and the plurality of opening and closing components 2 are arranged in parallel on the middle seat 5 at intervals, so that one opening and closing component 2 corresponds to one skeleton pressure plate 20, so that the plurality of skeleton pressure plates 2 can be disengaged and separated at the same time by the plurality of opening and closing components 2, which can further improve the work efficiency. In this embodiment, six opening and closing components 2 are provided, of which three are provided in a group, and two groups of opening and closing components 2 are relatively provided on the middle seat 5; correspondingly, the automatic opening and closing of six skeleton pressure plates 20 can be achieved at the same time. Here, the specific number of the opening and closing components 2 is not limited, and needs to be determined according to the actual opening and closing working conditions and layout structure.

[0057] Specifically, Figure 3 and Figure 4 As shown, the opening and closing body 21 includes a positioning seat 213, which is telescopically arranged along the Z axis below the middle seat 5. The positioning seat 213 can be positioned on the skeleton pressure plate 20, and a through hole 2131 is provided in the positioning seat 213. The clamping jaw 22 is inserted into the through hole 2131 and can move along the X axis or the Z axis in the through hole 2131.

[0058] By setting the positioning seat 213, the position of the skeleton pressing plate 20 can be positioned, so that the position of the clamping jaw 22 can be positioned relative to the skeleton pressing plate 20, which is conducive to the subsequent movement of the clamping jaw 22 to connect with the skeleton pressing plate 20, so that the clamping jaw 22 can drive the skeleton pressing plate 20 to disengage and separate from the skeleton mold 30 along the Z-axis relative to the skeleton mold 30, so as to facilitate the skeleton 10 to be directly removed from the skeleton mold 30.

[0059] Specifically, if Figures 3 to 6 As shown, a protrusion 2132 is provided on one of the positioning seat 213 and the skeleton pressing plate 20, and a positioning hole 201 is provided on the other, and the protrusion 2132 can be inserted into the positioning hole 201, so that the positioning seat 213 can be positioned on the skeleton pressing plate 20. In this embodiment, the protrusion 2132 is provided on the bottom end surface of the positioning seat 213, and the positioning hole 201 is provided on the top end surface of the skeleton pressing plate 20. In other embodiments, the positioning hole 201 can also be provided on the bottom end surface of the positioning seat 213, and the protrusion 2132 can be provided on the top end surface of the skeleton pressing plate 20, which is not specifically limited here.

[0060] Specifically, Figures 3 to 5 As shown, the opening and closing body 21 further includes a second driving member 212, the fixed end of the second driving member 212 is arranged on the middle seat 5, and the driving end of the second driving member 212 is connected to the positioning seat 213, that is, the output shaft of the second driving member 212 passes through the middle seat 5 to drive the positioning seat 213 to move along the Z axis. In this embodiment, the second driving member 212 can be specifically a linear cylinder.

[0061] By setting up the second driving member 212, when the clamp 22 drives the skeleton pressing plate 20 to move upward along the Z axis, the positioning seat 213 positioned with the skeleton pressing plate 20 can also move upward along the Z axis synchronously, avoiding the positioning seat 213 from interfering with the movement of the skeleton pressing plate 20 in the Z axis, thereby ensuring that the clamp 22 drives the skeleton pressing plate 20 to move smoothly upward along the Z axis.

[0062] Specifically, if Figure 5 As shown, an inner rod 2133 extending along the Z axis is provided on the positioning seat 213, and an outer rod 51 is fixedly connected to the middle seat 5. The inner rod 2133 is slidably provided in the outer rod 51 along the Z axis and can be stopped at any position, so as to drive the positioning seat 213 to slide along the Z axis relative to the middle seat 5.

[0063] Furthermore, if Figures 3 to 5As shown, the opening and closing body 21 also includes a third driving member 214, a connecting seat 215 and a fourth driving member 216; wherein the connecting seat 215 is slidably arranged on the inner side of the positioning seat 213 along the X-axis, the clamping jaw 22 is slidably arranged in the connecting seat 215 along the Z-axis, the fixed end of the third driving member 214 is installed on the connecting seat 215, the driving end of the third driving member 214 is connected to the clamping jaw 22, and the third driving member 214 is used to drive the clamping jaw 22 to move along the Z-axis in the connecting seat 215, so as to realize the movement of the clamping jaw 22 along the Z-axis in the through hole 2131 of the positioning seat 213; the fixed end of the fourth driving member 216 is connected to the positioning seat 213, the driving end of the fourth driving member 216 is connected to the connecting seat 215, and the fourth driving member 216 is used to drive the connecting seat 215 to move along the X-axis on the inner side of the positioning seat 213, so as to drive the clamping jaw 22 in the connecting seat 215 to move along the X-axis in the through hole 2131. The X-axis is parallel to the driving direction of the conveying axis of the fourth driving member 216 .

[0064] It is worth noting that if Figure 4 As shown, when the third driving member 214 and the fourth driving member 216 are working, the positioning seat 213 has been positioned on the skeleton pressing plate 20, that is, the positioning seat 213 and the skeleton pressing plate 20 remain stationary during this process. In this embodiment, the third driving member 214 and the fourth driving member 216 can be specifically linear cylinders.

[0065] By setting the third driving member 214 and the fourth driving member 216, the clamping jaw 22 can be driven to move along the Z-axis and the X-axis in the through hole 2131 of the positioning seat 213 to adjust the position of the clamping jaw 22 relative to the skeleton pressure plate 20, which is beneficial to realize the connection between the clamping jaw 22 and the skeleton pressure plate 20, thereby ensuring the smoothness and reliability of the connection between the clamping jaw 22 and the skeleton pressure plate 20.

[0066] Furthermore, if Figure 4 As shown, the end of the clamp 22 includes a connected arc surface 221 and a horizontal surface 222; an L-shaped cavity 202 is provided inside the skeleton pressing plate 20, and the L-shaped cavity 202 includes a connected vertical cavity 2021 and a horizontal cavity 2022, the vertical cavity 2021 extends along the Z axis, and the horizontal cavity 2022 extends along the X axis. The arc surface 221 at the end of the clamp 22 can penetrate into the vertical cavity 2021 downward along the Z axis, and the horizontal surface 222 at the end of the clamp 22 can penetrate into the horizontal cavity 2022 along the X axis, so that the horizontal surface 222 at the end of the clamp 22 abuts against the inner top wall surface 2023 of the horizontal cavity 2022, thereby realizing the connection between the clamp 22 and the skeleton pressing plate 20; then the clamp 22 is moved upward along the Z axis with the skeleton pressing plate 20 as a whole, so that the skeleton pressing plate 20 can be moved out of the skeleton mold 30 to realize the disengagement and separation between the skeleton pressing plate 20 and the skeleton mold 30.

[0067] like Figures 1 to 4As shown, by setting an opening and closing component 2 with a modular structure, and setting the above-mentioned L-shaped cavity 202 on the skeleton pressure plate 20, the L-shaped cavity 202 and the clamping claw 22 in the opening and closing component 2 are matched and used with each other, so that the above-mentioned L-shaped cavity 202 can be set on skeleton pressure plates 20 of various sizes, and the automatic opening and closing of skeleton pressure plates 20 of different sizes can be realized, so that the applicability and versatility of the entire opening and closing device are better.

[0068] like Figure 3 and Figure 4 As shown, in order to ensure the reliability of the connection between the skeleton pressing plate 20 and the skeleton mold 30 during winding, a clamping pin 50 is connected between the skeleton pressing plate 20 and the skeleton mold 30 to ensure the stability of the connection between the skeleton mold 30 and the skeleton pressing plate 20; when the skeleton pressing plate 20 needs to be detached from the skeleton mold 30, the clamping pin 50 needs to be pulled out in advance to ensure smooth detachment.

[0069] For this reason, Figure 3 and Figure 4 As shown, the opening and closing body 21 in this embodiment further includes a fifth driving member 217 and a plug-in member 211; wherein the fixed end of the fifth driving member 217 is connected to the middle seat 5, and the driving end of the fifth driving member 217 is connected to the plug-in member 211, and the plug-in member 211 is used to connect to the clamping pin 50, so that the fifth driving member 217 drives the plug-in member 211 and the clamping pin 50 to move in the direction away from the skeleton pressing plate 20 along the X-axis to release the connection between the skeleton mold 30 and the skeleton pressing plate 20 by the clamping pin 50. In this embodiment, the fifth driving member 217 can be specifically a linear cylinder.

[0070] By providing a fifth driving member 217 and a plug-in member 211 that cooperate with each other, the clamping pin 50 can be pulled out in advance to release the connection between the skeleton mold 30 and the skeleton pressing plate 20, which is beneficial for the subsequent clamping jaws 22 to drive the skeleton pressing plate 20 to move upward along the Z axis, so as to avoid the clamping pin 50 interfering with the movement of the skeleton pressing plate 20 on the Z axis.

[0071] Furthermore, if Figure 3 and Figure 5 As shown, an arc-shaped opening 2111 is provided on the end of the plug-in component 211 that is not connected to the fifth driving component 217, and the clamping pin 50 can be snapped into the arc-shaped opening 2111 to achieve the connection between the plug-in component 211 and the clamping pin 50, which can facilitate the pulling out of the clamping pin 50 through the plug-in component 211 under the drive of the fifth driving component 217.

[0072] By providing an arc-shaped opening 2111 that matches the clamping pin 50 , the connection between the plug-in component 211 and the clamping pin 50 can be directly achieved without additional operation, saving time and effort, making the connection between the clamping pin 50 and the plug-in component 211 simple and convenient.

[0073] It is worth explaining that the above-mentioned pulling out of the clamping pin 50 through the plug-in member 211 under the drive of the fifth driving member 217 specifically refers to the clamping pin 50 being pulled out of the skeleton pressure plate 20 but not pulled out of the skeleton mold 30, that is, the clamping pin 50 is not completely pulled out from the skeleton mold 30, so that the skeleton mold 30 can provide a certain support for the clamping pin 50.

[0074] It is worth noting that Figure 4 As shown, since the above-mentioned protrusion 2132 and positioning hole 201 for positioning are respectively provided on the positioning seat 213 and the skeleton pressure plate 20, when the protrusion 2132 is snapped into the positioning hole 201, the clamping pin 50 can be directly snapped into the arc-shaped opening 2111, that is, through the positioning effect between the protrusion 2132 and the positioning hole 201, the positioning connection effect between the plug-in component 211 and the clamping pin 50 can also be guaranteed.

[0075] Furthermore, due to the provision of the above-mentioned second driving member 212, when the clamping pin 50 is clamped into the arc-shaped opening 2111 and is directly pulled out of the skeleton pressing plate 20 by the plug-in member 211, at this time, since the plug-in member 211 needs to be kept pulled out by the fifth driving member 217, it is necessary to use the driving action of the second driving member 212 to drive the positioning seat 213 to move upward along the Z axis, and at the same time, the third driving member 214 drives the clamping claw 22 to move along the Z axis in the connecting seat 215, so as to drive the clamping claw 22 and the skeleton pressing plate 20 connected thereto to move along the Z axis; that is, the second driving member 212 drives the positioning seat 2 13 moves upward along the Z-axis, and at the same time, the third driving member 214 drives the clamping claw 22 to drive the skeleton pressing plate 20 to move upward along the Z-axis, so as to realize the synchronous movement of the positioning seat 213 and the skeleton pressing plate 20 along the Z-axis, so that the positioning seat 213 will not interfere with the upward movement of the skeleton pressing plate 20 along the Z-axis, and can drive the skeleton pressing plate 20 to move upward along the Z-axis to stagger the clamping pin 50. When the skeleton pressing plate 20 moves upward along the Z-axis to be completely located above the clamping pin 50, the plug-in member 211 moves upward along the Z-axis to release the connection between the plug-in member 211 and the clamping pin 50, so that the clamping pin 50 can be automatically reset.

[0076] That is, by providing the second driving member 212, the third driving member 214 and the fifth driving member 217 which cooperate with each other, when the fifth driving member 217 drives the plug-in member 211 to pull the clamping pin 50 out of the skeleton pressure plate 20, the skeleton pressure plate 20 and the clamping pin 50 can be completely offset, ensuring that when the plug-in member 211 is separated from the clamping pin 50, the clamping pin 50 will not interfere with the disengagement of the skeleton pressure plate 20.

[0077] Furthermore, the winding machine further includes an elastic member (not shown in the figure), one end of which is connected to the clamping pin 50, and the other end of which is connected to the skeleton mold 30. The elastic member is in a stretched state so that the elastic member can pull the clamping pin 50 along the X-axis into the skeleton mold 30 and the skeleton pressing plate 20. The elastic member in this embodiment can be specifically a tension spring.

[0078] By setting the elastic part, on the one hand, the clamping pin 50 can be tightly inserted into the skeleton mold 30 and the skeleton pressure plate 20, ensuring the tightness and stability of the connection between the clamping pin 50 and the skeleton mold 30 and the skeleton pressure plate 20, and avoiding the problem of separation between the skeleton mold 30 and the skeleton pressure plate 20; on the other hand, when the plug-in part 211 is removed from the clamping pin 50, the clamping pin 50 can automatically reset under the elastic force of the elastic part.

[0079] The specific working process of the opening and closing device in this embodiment is as follows:

[0080] The skeleton pressing plate 20 is separated from the skeleton mold 30:

[0081] First, the first driving member 4 drives the adapter seat 3 to move along the Z axis relative to the frame 1, so as to drive the entire opening and closing assembly 2 to move downward along the Z axis until the protrusion 2132 on the positioning seat 213 in the opening and closing body 21 is engaged with the positioning hole 201 on the skeleton pressure plate 20; at the same time, the arc-shaped opening 2111 on the plug-in member 211 is engaged with the clamping pin 50; at this time, part of the structure of the clamp 22 is located in the vertical cavity 2021 of the L-shaped cavity.

[0082] Afterwards, the fifth driving member 217 drives the plug-in member 211 to move along the X-axis to drive the clamping pin 50 to move along the X-axis in a direction away from the skeleton pressure plate 20 to release the connection between the skeleton mold 30 and the skeleton pressure plate 20 by the clamping pin 50. At this time, the clamping pin 50 is pulled out of the skeleton pressure plate 20 and is located inside the skeleton mold 30.

[0083] Then, the third driving member 214 drives the clamp 22 to move downward along the Z-axis in the connecting seat 215, so that the arc surface 221 at the end of the clamp 22 penetrates downward into the vertical cavity 2021 along the Z-axis; and then the fourth driving member 216 drives the clamp 22 to move along the X-axis in the through hole 2131 of the positioning seat 213, so that the horizontal surface 222 at the end of the clamp 22 penetrates into the transverse cavity 2022 along the X-axis, so that the horizontal surface 222 at the end of the clamp 22 abuts against the inner top wall surface 2023 of the transverse cavity 2022, so as to realize the connection between the clamp 22 and the skeleton pressure plate 20.

[0084] Then, the second driving member 212 drives the positioning seat 213 to move upward along the Z axis. Due to the positioning effect between the positioning seat 213 and the skeleton pressure plate 20, the positioning seat 213 can drive the skeleton pressure plate 20 to move upward along the Z axis to a certain extent; at the same time, the third driving member 214 drives the clamping claw 22 to drive the skeleton pressure plate 20 to move upward along the Z axis, so that the positioning seat 213 and the skeleton pressure plate 20 as a whole move synchronously along the Z axis; at this time, the fifth driving member 217 keeps driving the plug-in member 211 to move along the X axis, so that the clamping pin 50 is always pulled out of the skeleton pressure plate 20 and is located in the skeleton mold 30.

[0085] Finally, when the skeleton pressing plate 20 moves upward along the Z axis until it is completely offset from the clamping pin 50, that is, the skeleton pressing plate 20 is located above the clamping pin 50; then the first driving member 4 drives the adapter 3 to move upward along the Z axis relative to the frame 1, so as to drive the entire opening and closing assembly 2 and the skeleton pressing plate 20 to move upward along the Z axis as a whole, until the skeleton pressing plate 20 is completely disengaged from the skeleton mold 30; at the same time, since the pulling effect of the plug-in member 211 on the clamping pin 50 is released, the clamping pin 50 can be automatically reset under the action of the elastic member; thereby completing the entire process of the skeleton pressing plate 20 automatically disengaging from the skeleton mold 30, and then the skeleton 10 can be directly removed from the skeleton mold 30. Among them, the insertion and engagement of the skeleton pressing plate 20 into the skeleton mold 30 is opposite to the above-mentioned separation process, which will not be described in detail here, and the above-mentioned process of the skeleton pressing plate 20 automatically disengaging from the skeleton mold 30 can be referred to.

[0086] The opening and closing device in the present embodiment can realize the automatic disengagement and separation and plug-in engagement between the skeleton pressure plate 20 and the skeleton mold 30, thereby ensuring the smoothness and reliability of the opening and closing between the skeleton pressure plate 20 and the skeleton mold 30, saving time and effort; at the same time, due to the provision of a modular structure of the opening and closing component 2 and the L-shaped cavity 202 used in conjunction with the opening and closing component 2, the above-mentioned L-shaped cavity 202 can be provided on skeleton pressure plates 20 of various sizes, so that the clamping claws 22 in the opening and closing component 2 can be adapted to skeleton pressure plates 20 of various sizes, making the entire opening and closing device more applicable and universal.

The contents of this specification should not be understood as limiting the present invention.
