Description

Technical Field

[0001] This invention relates to the field of magnetic core assembly technology, and more specifically to an automated production equipment for assembling electronic transformer magnetic cores. Background Technology

[0002] In the field of electronic transformer manufacturing, the assembly of the magnetic core and the frame is one of the core processes, and its assembly quality directly affects the electrical performance and reliability of the transformer. Currently, the industry generally uses manual assistance or semi-automatic equipment to complete the picking, transfer, and pressing operations of the magnetic core. Operators need to manually remove the magnetic core from the feeding station, align it with the frame, and apply pressure to complete the assembly. This method of operation has many shortcomings. On the one hand, manual operation relies on experience, and it is difficult to guarantee the alignment accuracy of the magnetic core and the frame. Misalignment can easily lead to damage to the magnetic core or improper insertion, resulting in poor product consistency and low yield. On the other hand, manual assembly is inefficient, cannot meet the needs of large-scale continuous production, and involves high repetitive labor intensity and high labor costs.

[0003] Furthermore, while some existing automated equipment has achieved partial mechanization, it lacks effective control and precise positioning of the magnetic core's attitude. This can easily lead to wobbling or misalignment during transfer, and it cannot provide gradual and uniform clamping force during the pressing stage, resulting in sudden changes in resistance when the magnetic core is inserted, increasing the risk of breakage. Therefore, there is an urgent need for a fully automated assembly equipment that can automatically pick up and place the magnetic core, smoothly transfer it, accurately position it, and controllably press it, in order to overcome the technical bottleneck of balancing efficiency and quality in existing technologies. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic assembly production equipment for electronic transformer cores to solve the problems existing in the background art.

[0005] This invention provides the following technical solution: an automatic assembly production equipment for electronic transformer cores, comprising a first conveying device, a second conveying device, and a mounting frame. The mounting frame is equipped with a transfer mechanism and a positioning mechanism.

The first conveying device is used to convey the frame of the electronic transformer to the assembly station. The second conveying device is used to convey the core of the electronic transformer to a preset material picking position. The transfer mechanism is used to transfer the positioning mechanism and the clamped core from the second conveying device to the assembly station. The positioning mechanism is used to clamp and fix the core and release the core to the pressing mechanism after reaching the assembly station. The pressing mechanism is used to guide and limit the core and press the core into the frame.

[0006] Preferably, the transfer mechanism includes a moving rod, a motor, and a rotating assembly. Two rotating assemblies are provided. Each rotating assembly includes a rotating shaft, a connecting shaft, and a connecting rod. The rotating shaft is rotatably mounted on the mounting frame, the connecting shaft is fixedly mounted on the moving rod, one end of the connecting rod is fixedly connected to the surface of the rotating shaft, and the other end of the connecting rod is rotatably connected to the surface of the connecting shaft.

[0007] Preferably, the two connecting rods are arranged in parallel, the motor is fixedly mounted on the mounting bracket, and the motor output end is fixedly connected to one end of any rotating shaft.

[0008] Preferably, the positioning mechanism includes a fixed shell and a movable component. The top of the fixed shell is fixedly connected to one end of the moving rod. A rotary cylinder is fixedly installed inside the fixed shell. A rotating plate is fixedly connected to the output end of the rotary cylinder. A main pin is fixedly connected to the top of the rotating plate. There are two main pins, and the two main pins are centrally symmetrically distributed.

[0009] Preferably, there are two movable components corresponding to the main pin. The movable component includes a clamping member, a movable rod, and a guide rod. The top of the clamping member is fixedly connected to a secondary pin. The movable rod is located between the main pin and the secondary pin, with one end of the movable rod rotatably connected to the main pin and the other end of the movable rod rotatably connected to the secondary pin. The guide rod is fixedly installed in the fixed housing, and the clamping member is sleeved on the surface of the guide rod.

[0010] Preferably, the two clamping members are provided with clamping planes on the side close to each other, the clamping planes are located at the bottom of the fixed shell, and the two clamping members are fixedly connected to support frames on the side opposite to each other, with rollers rotatably installed at the bottom of the support frames.

[0011] Preferably, the pressing mechanism includes guide bars and a stabilizing frame. There are four guide bars, which are arranged in a vertical V-shaped structure. The four guide bars are fixedly connected to each other by a fixing frame. A receiving frame is fixedly connected to the fixing frame. There are two receiving frames arranged symmetrically. Each of the two receiving frames has a guide slope on one side close to each other. The spacing between the guide slopes decreases in the vertically downward direction.

[0012] Preferably, a sliding plate is fixedly connected to the fixed frame, a sliding rod is fixedly connected to the stabilizing frame, the axis of the sliding rod is arranged vertically, the sliding plate is sleeved on the surface of the sliding rod, a return spring is sleeved on the surface of the sliding rod, and the stabilizing frame is fixed to the ground by a bracket.

[0013] Preferably, the guide bar is provided with a trigger component, and four trigger components are provided corresponding to the guide bar. The trigger component includes a through hole, a firing block and a fixing post.

[0014] Preferably, the through hole is formed on the guide bar, the firing block passes through the through hole, one end of the fixing post is fixedly connected to the guide bar, the firing block is sleeved on the surface of the fixing post, a compression spring is sleeved on the surface of the fixing post, and the firing block is provided with a triggering slope and a pressing plane.

[0015] The beneficial effects of this invention are: In this invention, the coordinated operation of the transfer mechanism, positioning mechanism, and pressing mechanism achieves fully automated operation of the magnetic core from feeding, clamping, transfer to pressing, significantly improving assembly efficiency and product consistency. Specifically, the transfer mechanism adopts a structural design with dual rotating components and parallel connecting rods, which can drive the moving rod to always move in an arc parallel to the ground, thereby ensuring that the positioning mechanism and the clamped magnetic core maintain a stable spatial orientation during the transfer process and avoiding positioning deviations caused by tilting or swaying. In the positioning mechanism, a rotary cylinder drives a rotating plate to move the main pin shaft, which in turn pushes the clamping parts to move synchronously towards or away from each other along the guide rod via a movable rod. This achieves rapid clamping and releasing of the magnetic core. The clamping plane fits tightly against the surface of the magnetic core, ensuring both stability during transport and timely release before pressing to avoid interference. Meanwhile, the rollers on the outside of the clamping parts roll in cooperation with the guide slope of the receiving frame during the pressing stage, converting the opening action of the clamping parts into a downward driving force for the pressing mechanism. This allows for secondary pressing of the magnetic core without the need for an additional power source, resulting in a compact, energy-efficient, and high-performance structure. In the pressing mechanism, vertically arranged V-shaped guide bars provide guidance and limit for the falling magnetic core, ensuring that the magnetic core accurately falls into the frame. The firing block of the trigger component first retracts and then resets under the weight of the magnetic core, forming a staged blocking and releasing mechanism. This allows the magnetic core to be initially inserted by gravity, and then the pressing plane provides additional clamping force to complete the final assembly. This two-step pressing method effectively avoids rigid impact, reduces the risk of magnetic core damage, and ensures the consistency and reliability of insertion depth. In addition, the cooperation of the fixed frame, sliding plate, and return spring allows the pressing mechanism to automatically reset after completing one assembly. Combined with the intermittent movement of the conveying device, continuous cyclic operation can be achieved without manual intervention, greatly reducing labor intensity and improving the degree of automation.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1 to 4This invention provides an automated assembly production equipment for electronic transformer cores, comprising a first conveying device 1, a second conveying device 2, and a mounting frame 3. The mounting frame 3 is equipped with a transfer mechanism 4 and a positioning mechanism 5. The first conveying device 1 is equipped with an assembly station, and a pressing mechanism 6 is provided at the assembly station. The first conveying device 1 is used to transport the electronic transformer frame to the assembly station. The second conveying device 2 is used to transport the electronic transformer core to a preset material picking position. The transfer mechanism 4 is used to transfer the positioning mechanism 5 and the clamped core from the second conveying device 2 to the assembly station. The positioning mechanism 5 is used to clamp and fix the core and release it to the pressing mechanism 6 after reaching the assembly station. The pressing mechanism 6 is used to guide and limit the core and press it into the frame.

[0030] In addition, the first conveying device 1 is also equipped with a clamping device, which adopts a conventional pneumatic or electric gripper structure in the art. This device is used to position and clamp the skeleton after it is conveyed to the assembly station, ensuring that the skeleton remains in a fixed position during the subsequent magnetic core insertion and pressing process, thereby increasing stability. Since this clamping device is a well-known technology in the art, its specific structure and control method will not be described in detail here.

[0031] Reference Figures 1 to 7 The transfer mechanism 4 includes a moving rod 41, a motor 45, and two rotating components. Each rotating component includes a rotating shaft 42, a connecting shaft 43, and a connecting rod 44. The rotating shaft 42 is rotatably mounted on the mounting frame 3, the connecting shaft 43 is fixedly mounted on the moving rod 41, one end of the connecting rod 44 is fixedly connected to the surface of the rotating shaft 42, and the other end is rotatably connected to the surface of the connecting shaft 43. The two connecting rods 44 are arranged in parallel. The motor 45 is fixedly mounted on the mounting frame 3, and its output end is fixedly connected to one end of either rotating shaft 42. The transfer mechanism 4 uses two rotating components in conjunction with two parallel connecting rods 44. Driven by the motor 45, the moving rod 41 always moves in an arc parallel to the ground, thus ensuring that the positioning mechanism 5 and the held magnetic core maintain a stable spatial orientation during the transfer process.

[0032] The positioning mechanism 5 includes a fixed housing 51 and movable components 53. The top of the fixed housing 51 is fixedly connected to one end of the moving rod 41. A rotary cylinder is fixedly installed inside the fixed housing 51. A rotating plate 52 is fixedly connected to the output end of the rotary cylinder. A main pin 521 is fixedly connected to the top of the rotating plate 52. There are two main pins 521, which are centrally symmetrically distributed. The rotary cylinder directly drives the rotating plate 52 to drive the two centrally symmetrical main pins 521 to move synchronously. The main pins 521 can evenly transmit the rotational motion to the movable components 53 on both sides, ensuring a symmetrical distribution of clamping force. At the same time, the structure is compact, which helps to save installation space.

[0033] Two movable components 53 are provided corresponding to the main pin 521. The movable component 53 includes a clamping member 531, a movable rod 532, and a guide rod 534. The top of the clamping member 531 is fixedly connected to the secondary pin 533. The movable rod 532 is located between the main pin 521 and the secondary pin 533, with one end of the movable rod 532 rotatably connected to the main pin 521 and the other end of the movable rod 532 rotatably connected to the secondary pin 533. The guide rod 534 is fixedly installed inside the fixed housing 51. The clamping member 531 is sleeved on the surface of the guide rod 534. The two clamping members 531 are provided with clamping planes 5311 on the side close to each other. The clamping planes 5311 are located at the bottom of the fixed housing 51. The two clamping members 531 are fixedly connected to support frames 535 on the side away from each other. Rollers 536 are rotatably installed at the bottom of the support frames 535. The rotating engagement of the movable rod 532 with the main pin 521 and the auxiliary pin 533 drives the clamping member 531 to move synchronously towards or away from each other along the guide rod 534, thereby achieving rapid clamping and loosening of the magnetic core. The clamping plane 5311 is in close contact with the surface of the magnetic core to ensure the stability during the transfer process. The roller 536 installed on the outside of the clamping member 531 through the support frame 535 can cooperate with the subsequent pressing mechanism 6 when the clamping member 531 is opened.

[0034] In use, the first conveying device 1 conveys the frame of the electronic transformer, and the second conveying device 2 conveys the magnetic core of the electronic transformer. When the frame moves to the assembly station, the magnetic core also moves to the preset position simultaneously. At this time, both the first conveying device 1 and the second conveying device 2 stop conveying. Then, the rotary cylinder drives the rotating plate 52 to rotate around its own axis. The rotation of the rotating plate 52 drives the two clamping members 531 to move synchronously along the guide rod 534 towards each other through the movable rod 532. The clamping members 531 clamp and fix the magnetic core through the clamping plane 5311. Subsequently, the motor 45 drives the rotating shaft 42 to rotate around its own axis. The rotating shaft 42 rotates and drives the connecting rod 44 to rotate synchronously around the axis of the rotating shaft 42. Under the constraint of the two connecting rods 44, the moving rod 41 always remains parallel to the ground, and the moving rod 41 drives the positioning mechanism 5 and the magnetic core to move synchronously with the connecting rod 44, and transfers the positioning mechanism 5 and the magnetic core from the second conveying device 2 to the assembly station.

[0035] In summary, the transfer mechanism 4 employs a dual-rotation assembly with two parallel connecting rods 44, ensuring that the moving rod 41, driven by the motor 45, always moves in an arc parallel to the ground. This ensures that the fixed shell 51 and the clamped magnetic core maintain a constant spatial orientation throughout the transfer process from the second conveying device 2 to the assembly station, completely avoiding positioning deviations caused by tilting or swaying, and laying the foundation for precise docking with the pressing mechanism 6. In the positioning mechanism 5, a rotary cylinder drives a rotating plate 52, which in turn drives two centrally symmetrical main pins 521, which, through the movable rod 532, push the clamping component 531 along... Guide rods 534 move synchronously in opposite directions to achieve rapid clamping and releasing of the magnetic core. In addition, rollers 536 mounted on the outside of the clamping member 531 via the support frame 535 can roll in cooperation with the pressing mechanism 6 during the opening of the clamping member 531, converting the driving force of the clamping action into downward pressure on the pressing mechanism 6. Secondary pressing can be triggered without an additional power source, simplifying the transmission chain and reducing equipment energy consumption and control complexity. The entire process is smooth and continuous, shortening the single cycle time, while avoiding the uncertainty of manual operation, effectively improving the consistency and yield of magnetic core assembly.

[0036] Reference Figures 1 to 10 The pressing mechanism 6 includes guide bars 61 and a stabilizing frame 64. Four guide bars 61 are arranged in a vertically oriented V-shaped structure. The four guide bars 61 are fixedly connected by a fixing frame 62. A receiving frame 63 is fixedly connected to the fixing frame 62. Two receiving frames 63 are symmetrically arranged, and each receiving frame 63 has a guide slope 631 on one side close to the other. The spacing of the guide slopes 631 decreases vertically downwards. The four vertically arranged V-shaped guide bars 61 provide circumferential limiting and centering guidance when the magnetic core falls, ensuring that the magnetic core is always aligned correctly with the frame, effectively avoiding insertion jamming due to misalignment. The two symmetrically arranged receiving frames 63 and guide slopes 631 can form a rolling engagement with the roller 536 when the clamping member 531 opens, smoothly converting the clamping force into overall downward pressure on the fixing frame 62, simplifying the transmission structure of the pressing mechanism 6.

[0037] A sliding plate 65 is fixedly connected to the fixed frame 62, and a sliding rod 66 is fixedly connected to the stabilizing frame 64. The axis of the sliding rod 66 is arranged vertically. The sliding plate 65 is sleeved on the surface of the sliding rod 66, and a return spring 67 is sleeved on the surface of the sliding rod 66. The stabilizing frame 64 is fixed to the ground by a bracket. The vertically arranged sliding rod 66 provides precise vertical movement guidance for the entire fixed frame 62, ensuring the consistency of the force direction during the pressing process and avoiding uneven loading. The return spring 67 can automatically release its elasticity after pressing, driving the fixed frame 62 and the guide bar 61 to smoothly rise back to the initial position, realizing automatic reset.

[0038] A trigger component 68 is provided on the guide bar 61. There are four trigger components 68 corresponding to the guide bar 61. The trigger component 68 includes a through hole 681, a firing block 682 and a fixing post 683. The through hole 681 is opened on the guide bar 61. The firing block 682 passes through the through hole 681. One end of the fixing post 683 is fixedly connected to the guide bar 61. The firing block 682 is sleeved on the surface of the fixing post 683. A compression spring 684 is sleeved on the surface of the fixing post 683. The firing block 682 is provided with a triggering inclined surface 6821 and a pressing surface 6822. The trigger ramp 6821 on the firing block 682 can smoothly retract along the fixing post 683 under the action of the magnetic core's own weight, allowing the magnetic core to overcome the obstruction and achieve initial insertion. The compression spring 684 automatically resets after the magnetic core has passed. Subsequently, the pressing plane 6822 of the firing block 682 applies a uniform additional clamping force to the top of the magnetic core during the overall pressing process, completing the final assembly. This two-step pressing method achieves progressive and flexible pressure application, effectively avoiding damage to the magnetic core caused by rigid impact, while ensuring the consistency of insertion depth.

[0039] When in use, when the positioning mechanism 5 and the magnetic core as a whole are transferred to the assembly station by the second conveying device 2, the bottom of the magnetic core is moved to the area between the four guide bars 61, and the guide bars 61 limit the magnetic core. Subsequently, the rotary cylinder drives the rotating plate 52 to rotate around its own axis in the opposite direction. Similarly, the two clamping members 531 move synchronously along the guide rod 534 in opposite directions. The clamping members 531 release their clamping and fixing of the magnetic core. Under the action of its own gravity, the magnetic core moves downward along the guide bar 61. During this process, the magnetic core contacts the triggering inclined surface 6821 of the firing block 682. Under the compression of the magnetic core's own weight, the firing block 682 slides along the fixed post 683 and releases its obstruction to the magnetic core. The compression spring 684 contracts and increases its elastic force under the compression of the firing block 682. When the magnetic core passes the firing block 682 and moves below the firing block 682, the elastic force of the compression spring 684 is released and drives the firing block 682 back to its initial position. At this time, the magnetic core is partially inserted into the frame (due to the damping between the frame and the magnetic core, the magnetic core cannot be fully inserted into the frame without the application of external force and relying only on its own weight). Afterwards, the rotary cylinder continues to drive the rotating plate 52 to rotate around its own axis in the opposite direction. The two clamping parts 531 continue to move along the guide rod 534 in opposite directions. The movement of the clamping parts 531 drives the two rollers 536 to move synchronously in opposite directions. While the rollers 536 are moving, they roll along the guide slope 631. Under the squeezing action of the rollers 536, the receiving frame 63, the fixing frame 62, the guide bar 61, the triggering component 68 and the sliding plate 65 move downward along the sliding rod 66 as a whole. The reset spring 67 contracts and its elastic force increases under the squeezing of the sliding plate 65. At the same time, the firing block 682 presses down on the top of the magnetic core through the pressing plane 6822. The magnetic core is gradually inserted into the skeleton, completing the assembly of the magnetic core and the skeleton. Afterwards, the motor 45 drives the rotating shaft 42 to rotate in the opposite direction around its own axis. Similarly, the motion rod 41 drives the positioning mechanism 5 back to the initial position, the roller 536 releases the pressure on the guide slope 631, the elastic force of the return spring 67 is released and drives the receiving frame 63, the fixed frame 62, the guide strip 61, the trigger component 68 and the sliding plate 65 back to the initial position as a whole. At the same time, the first conveying device 1 drives the assembled magnetic core and skeleton to leave the assembly station and enter the subsequent processing equipment. The next skeleton comes to the assembly station under the drive of the first conveying device 1, and the next magnetic core comes to the preset position under the drive of the second conveying device 2.

[0040] In summary, in the pressing mechanism 6, the four vertically arranged V-shaped guide bars 61 provide circumferential limiting when the magnetic core falls, ensuring that the magnetic core is always aligned with the frame in the correct posture, avoiding insertion jamming or magnetic core damage caused by misalignment; the firing block 682 in the trigger assembly 68, which passes through the guide bar 61, works with the compression spring 684 to first retract along the fixed post 683 under the action of the magnetic core's own weight to release the obstruction, and then automatically resets after the magnetic core has passed, so that the magnetic core first completes the centering pre-insertion by its own weight, and then the pressing plane 6822 of the firing block 682 applies a uniform additional clamping force to complete the final assembly. This progressive pressing method effectively avoids rigid impact, reduces the risk of magnetic core breakage, and ensures the consistency and reliability of the insertion depth; the guide slope 631 on the receiving frame 63 and the outer roller 53 of the clamping member 531 The rolling mechanism transforms the opening action of the clamping component 531 into a driving force for the downward movement of the fixed frame 62 and guide strip 61 as a whole. This eliminates the need for an independent power source, enabling secondary pressing and simplifying the transmission structure while reducing energy consumption. The vertically arranged sliding rod 66 on the stabilizing frame 64, along with the reset spring 67 fitted onto it, and the sliding plate 65, allow the entire pressing assembly to automatically and smoothly reset after one assembly. This seamlessly connects with the intermittent movements of the first conveying device 1 and the second conveying device 2, ensuring the stability of continuous cyclical operations. The entire process requires no manual intervention, significantly improving automation. Furthermore, while increasing assembly efficiency, precise force control effectively ensures product yield, solving the technical problems of high impact force, difficult alignment, and low efficiency in traditional pressing methods.

[0041] The working principle of this invention is as follows: the first conveying device 1 conveys the frame of the electronic transformer, and the second conveying device 2 conveys the magnetic core of the electronic transformer. When the frame moves to the assembly station, the magnetic core also moves synchronously to the preset position. At this time, both the first conveying device 1 and the second conveying device 2 stop conveying.

[0042] Then, the rotary cylinder drives the rotating plate 52 to rotate around its own axis. The rotation of the rotating plate 52 drives the two clamping members 531 to move synchronously along the guide rod 534 towards each other through the movable rod 532. The clamping members 531 clamp and fix the magnetic core through the clamping plane 5311.

[0043] Subsequently, the motor 45 drives the rotating shaft 42 to rotate around its own axis. The rotating shaft 42 rotates and drives the connecting rod 44 to rotate synchronously around the axis of the rotating shaft 42. Under the constraint of the two connecting rods 44, the moving rod 41 always remains parallel to the ground. The moving rod 41 drives the positioning mechanism 5 and the entire magnetic core to move synchronously with the connecting rod 44, and transfers the positioning mechanism 5 and the entire magnetic core from the second conveying device 2 to the assembly station. The bottom of the magnetic core is moved to the area between the four guide bars 61, and the guide bars 61 limit the magnetic core.

[0044] Afterwards, the rotary cylinder drives the rotating plate 52 to rotate around its own axis in the opposite direction. Similarly, the two clamping parts 531 move synchronously along the guide rod 534 in opposite directions. The clamping parts 531 release their clamping and fixing of the magnetic core. Under the action of its own gravity, the magnetic core moves downward along the guide bar 61. During this process, the magnetic core contacts the triggering inclined surface 6821 of the firing block 682. Under the compression of the magnetic core's own weight, the firing block 682 slides along the fixed post 683 and releases its obstruction to the magnetic core. The compression spring 684 contracts and increases its elastic force under the compression of the firing block 682. When the magnetic core passes the firing block 682 and moves below the firing block 682, the elastic force of the compression spring 684 is released and drives the firing block 682 back to its initial position. At this time, the magnetic core is partially inserted into the frame (due to the damping between the frame and the magnetic core, the magnetic core cannot be fully inserted into the frame without the application of external force and relying only on its own weight).

[0045] Afterwards, the rotary cylinder continues to drive the rotating plate 52 to rotate around its own axis in the opposite direction. The two clamping parts 531 continue to move along the guide rod 534 in opposite directions. The movement of the clamping parts 531 drives the two rollers 536 to move synchronously in opposite directions. While the rollers 536 are moving, they roll along the guide slope 631. Under the squeezing action of the rollers 536, the receiving frame 63, the fixing frame 62, the guide bar 61, the triggering component 68 and the sliding plate 65 move downward along the sliding rod 66 as a whole. The reset spring 67 contracts and its elastic force increases under the squeezing of the sliding plate 65. At the same time, the firing block 682 presses down on the top of the magnetic core through the pressing plane 6822. The magnetic core is gradually inserted into the skeleton, completing the assembly of the magnetic core and the skeleton.

[0046] Afterwards, the motor 45 drives the rotating shaft 42 to rotate in the opposite direction around its own axis. Similarly, the motion rod 41 drives the positioning mechanism 5 back to the initial position, the roller 536 releases the pressure on the guide slope 631, the elastic force of the return spring 67 is released and drives the receiving frame 63, the fixed frame 62, the guide strip 61, the trigger component 68 and the sliding plate 65 back to the initial position as a whole. At the same time, the first conveying device 1 drives the assembled magnetic core and skeleton to leave the assembly station and enter the subsequent processing equipment. The next skeleton comes to the assembly station driven by the first conveying device 1, and the next magnetic core comes to the preset position driven by the second conveying device 2. The above steps are repeated, and so on.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
