Description

Technical Field

[0001] This invention relates to the field of forming mold technology, and in particular to a hot pressing forming device for metal parts with optical module positioning function. Background Technology

[0002] Hot pressing forming equipment is a specialized device used to optimize the appearance of metal parts and improve their surface flatness. During the forming process, this equipment uses heat treatment to rearrange and refine the grain structure within the metal, effectively eliminating residual internal stress. Then, pressure is applied to the metal parts using a specially designed mold to ensure the surface achieves the desired flatness, thus successfully completing the forming and correction process.

[0003] However, in practical applications, especially for hot pressing and forming of sheet metal, current hot pressing and forming equipment often relies on suction cups to grip and transport the metal sheet to a preset mold position. Because the mold operates at high temperatures, the suction cups are exposed to a high-temperature environment for extended periods. This environmental factor causes the suction cup material to gradually age and harden, weakening its sealing performance with the metal parts. As the seal deteriorates, the suction cup's adsorption force on the metal parts weakens, and it may even detach, increasing the risk of displacement of the metal parts during transportation. This not only affects the accuracy of part placement but can also lead to mold damage or substandard finished product quality. Summary of the Invention

[0023] Vibration components, the same number as the number of air tubes, are all mounted on the frame and are used to drive the air tubes to shake. Each vibration component includes:

[0030] The beneficial effects of this invention are as follows: This invention controls the position of the fixing plate through an optical module, enabling the suction cup to precisely fix the metal part. When the seal between the suction cup and the metal part decreases, a torsion spring drives the second elastic telescopic rod and the support plate to rotate, moving the support plate below the metal part to support the position where the suction cup cannot be fixed, thus improving the accuracy of the metal part's placement. During the process of placing the metal part into the lower mold, the transmission rod moves along the vibrating plate, causing the suction cup to drive the metal part to move back and forth through friction, ensuring that the protruding positions on the metal part are aligned with the corresponding positions on the lower mold, thus ensuring the accuracy of the metal part's shaping. During the reciprocating swing of the metal part, the L-shaped plate restricts the position of the air tube, preventing the pressure between the suction cup and the metal part from increasing, thus avoiding excessive pressure from the suction cup on the metal part, which could prevent the metal part from moving and affect the adjustment of the metal part's position.

Detailed Implementation

[0042] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0043] A hot pressing and shaping device for metal parts with optical module positioning function, such as Figures 1-6 As shown, it includes: a frame 1, a hydraulic push rod 2, an upper mold 3 fixedly connected to the telescopic end of the hydraulic push rod 2, a lower mold 4, two linear slide groups 5, a fixed plate 6 at the moving end of the linear slide group 5, an optical module for controlling the moving distance of the fixed plate 6 on the linear slide group 5, multiple first elastic telescopic rods 7 fixedly connected to the fixed plate 6, a connecting ring 8 fixedly connected to the telescopic end of the first elastic telescopic rod 7, an air pipe 9 connected to the connecting ring 8, a suction cup 10 connected to the air pipe 9, a connecting frame 11 fixedly connected to the air pipe 9, a second elastic telescopic rod 12 rotatably connected to the connecting frame 11, and a torsion spring 13 fixedly connected between the two, a support plate 14 fixedly connected to the telescopic end of the second elastic telescopic rod 12, the support plate 14 for supporting the metal parts, and a limiting mechanism for limiting the support plate 14 on the air pipe 9.

[0044] The above solution provides a way to quickly fix the corresponding area of ​​the metal part when the fixation of the suction cup 10 on the metal part weakens, preventing the metal part from shifting after separating from the suction cup 10 and affecting the normal processing of the metal part; an induction heater is provided inside the frame 1, and a storage rack is provided on the rear side of the frame 1. The storage rack is used to store the shaped metal parts and to heat the upper mold 3 and lower mold 4. Both the upper mold 3 and lower mold 4 are used to extrude the surface of the metal part to improve the flatness of the metal part surface; multiple guide pillars are provided on the upper mold 3, and the guide pillars are slidably connected to the frame 1. To increase the stability of the upper mold 3 during movement, a positioning module is installed on the frame 1. The positioning module consists of an electric push rod and a baffle. The baffle is used to limit the position of the metal part's edge. The metal part is moved by the extension end of the electric push rod, so that the edge of the metal part fits against the adjacent baffle, thereby adjusting the position of the metal part and reducing the deviation between the metal part and the mold. The linear slide group 5 is an existing device, and its specific structure will not be described in detail. The linear slide group 5 is used to drive the fixed plate 6 to move up and down and back and forth. Initially, the fixed plate 6 and the parts on it are located at... Between the upper mold 3 and the lower mold 4, the position of the fixed plate 6 shown in the figure is its alignment with the metal part. The optical module is an existing device used to detect whether the linear slide group 5 has moved the fixed plate 6 to a specified distance. The specific structure will not be described in detail. In this embodiment, the telescopic end of the first elastic telescopic rod 7 does not move. The first elastic telescopic rod 7 can be regarded as a straight rod. In this embodiment, the connection between the connecting ring 8 and the air pipe 9 can be regarded as a fixed connection. An air pump is connected to the air pipe 9. The air pump generates negative pressure by drawing gas from the air pipe 9 to fix the metal part with the suction cup 10. The suction cup 10 is made of high-temperature resistant rubber material. Made of a material, when the suction cup 10 is pressed into contact with the metal part, the suction cup 10 deforms and increases the contact area between it and the metal part. Initially, the extension end of the second elastic telescopic rod 12 is in the extended state, and the torsion spring 13 is initially in the stored state. The torsion spring 13 is used to drive the second elastic telescopic rod 12 to rotate 90°. Initially, the extension end of the second elastic telescopic rod 12 is in the extended state, and the support plate 14 is located below the suction cup 10. The support plate 14 is used to support the part from the bottom to complete the fixation. The limiting mechanism is used to limit the initial angle of the second elastic telescopic rod 12.

[0045] Furthermore, such as Figures 6-8 As shown, the limiting mechanism includes: a third elastic telescopic rod 15, fixedly connected to the air pipe 9, with a limiting rod 16 fixedly connected to the telescopic end of the third elastic telescopic rod 15; a limiting groove provided in the telescopic part of the second elastic telescopic rod 12; the limiting rod 16 sliding within the limiting groove of the telescopic part of the second elastic telescopic rod 12; and an air inlet and an air outlet provided in the fixed part of the third elastic telescopic rod 15; an adjustment component provided on the third elastic telescopic rod 15; and a power component provided on the air pipe 9; for driving the telescopic end of the third elastic telescopic rod 15 to move.

[0046] Furthermore, such as Figure 8 As shown, the diameter of the air inlet on the fixing part of the third elastic telescopic rod 15 is not less than the diameter of the air outlet on it.

[0047] The above solution provides a way to restrict the rotation of the second elastic telescopic rod 12; the end of the limiting rod 16 near the second elastic telescopic rod 12 is a hemispherical head, which is used to facilitate the limiting rod 16 entering the limiting groove of the second elastic telescopic rod 12. The depth of the upper limiting groove of the second elastic telescopic rod 12 is greater than the radius of the upper hemispherical head of the limiting rod 16, which is used to ensure that the limiting rod 16 cannot separate from the limiting groove of the second elastic telescopic rod 12 on its own. The diameter of the air inlet on the third elastic telescopic rod 15 is not less than the diameter of the air outlet on it, ensuring that the telescopic end of the third elastic telescopic rod 15 does not move when the air inlet is not sealed.

[0048] Furthermore, such as Figures 6-8 As shown, the adjustment assembly includes: a sealing frame 19, which is slidably connected to the fixing part of the third elastic telescopic rod 15. The sealing frame 19 is used to seal the air inlet on the fixing part of the third elastic telescopic rod 15. An adjustment block 1901 is fixedly connected to the sealing frame 19. An inclined surface is provided on the lower side of the adjustment block 1901. A tension spring 20 is provided between the sealing frame 19 and the air pipe 9.

[0049] Furthermore, such as Figures 4-7 As shown, the adjustment assembly also includes: an adjustment ring 17, fixed to the suction cup 10, the adjustment ring 17 being in contact with the air tube 9; and a trapezoidal block 18, fixed to the adjustment ring 17, the trapezoidal block 18 being used to push the adjustment block 1901 to move.

[0050] The above solution provides a method for sealing the air inlet of the third elastic telescopic rod 15 after the suction cup 10 contacts the metal part; the sealing frame 19 is composed of a full ring and a half ring, wherein the half ring of the sealing frame 19 is used to block the air inlet on the third elastic telescopic rod 15, and the length of the half ring is greater than the diameter of the air inlet on the third elastic telescopic rod 15; the tension spring 20 is used to drive the sealing frame 19 to reset; the cross section of the trapezoidal block 18 is a right trapezoid, and the inclined surface of the trapezoidal block 18 is used to press the inclined surface of the adjusting block 1901, so that the adjusting block 1901 drives the sealing frame 19 to move.

[0051] Furthermore, such as Figures 5-7 As shown, the power assembly includes: a fourth elastic telescopic rod 21, fixed to the air pipe 9, with the fixed part of the fourth elastic telescopic rod 21 communicating with the air pipe 9; an arc-shaped frame 22, fixed to the telescopic end of the fourth elastic telescopic rod 21, the arc-shaped frame 22 being slidably connected to the fixed part of the third elastic telescopic rod 15, and the arc-shaped frame 22 being fixedly connected to a connecting pipe for connecting the third elastic telescopic rod 15 and the air pipe 9.

[0052] Furthermore, such as Figures 6-8As shown, it also includes: piston plates 901, the same number as the number of air tubes 9, which are slidably connected to adjacent air tubes 9 respectively. A first spring 902 is fixed between the piston plate 901 and the air tube 9. The piston plate 901 divides the air tube 9 into upper and lower chambers. A third elastic telescopic rod 15 is connected to the upper chamber of the air tube 9, and a fourth elastic telescopic rod 21 is connected to the lower chamber of the air tube 9.

[0053] The above solution provides a method for extracting gas from the third elastic telescopic rod 15 after the fixing force of the suction cup 10 on the metal part is reduced; initially, the telescopic end of the fourth elastic telescopic rod 21 is in the extended state; an annular protrusion is provided in the air pipe 9 to restrict the position of the piston plate 901, so that the piston plate 901 cannot move to the connection between the air pipe 9 and its upper connecting pipe; the first spring 902 is used to push the piston plate 901 to reset; the rate at which the gas in the third elastic telescopic rod 15 enters the air pipe 9 is much smaller than the rate at which the air pump extracts the gas in the air pipe 9, so that the normal movement of the piston plate 901 is not affected.

[0054] Furthermore, such as Figure 3 As shown, the frame 1 has the same number of reset blocks 141 as the support plates 14 fixed inside it. The reset blocks 141 are provided with inclined surfaces and are used to squeeze and rotate the adjacent support plates 14.

[0055] The above solution provides a method to reset the support plate 14 during the process of placing the metal part into the lower mold 4; there are four reset blocks 141 on the frame 1. Taking the direction of the inclined surface on the right rear reset block 141 as an example, the inclined surface on the reset block 141 faces the right front. When the metal part is placed into the lower mold 4, the inclined surface of the reset block 141 presses the support plate 14, causing the support plate 14 to rotate and move out from the underside of the metal part.

[0056] Workflow: When hot pressing is required to trim metal parts, the worker places the metal parts between the electric push rod and the baffle using the existing feeding device. Then, the worker starts the electric push rod, and the telescopic end of the electric push rod extends and pushes the metal part to the right until the right side of the metal part contacts the baffle. Then, the telescopic end of the electric push rod stops moving and completes the initial calibration of the metal part. After that, the worker starts the two linear slide groups 5, which drive the parts on them to move forward.

[0057] The following example uses the movement direction of the right-side linear slide group 5 and its parts. During the forward movement of the linear slide group 5, the linear slide group 5 drives the two first elastic telescopic rods 7 to move forward through the fixed plate 6. The telescopic ends of the first elastic telescopic rods 7 drive the adjacent air pipes 9 and their parts to move forward through the connecting ring 8. When the linear slide group 5 moves to the designated position, it stops moving forward. At this time, the center line of the fixed plate 6 and the center line of the metal part are on the same vertical plane. The linear slide group 5 drives the first elastic telescopic rods 7 and their parts to move downward through the fixed plate 6. As the first elastic telescopic rods 7 move downward, the first elastic telescopic rods 7 drive the air pipes 9 to move downward through the connecting ring 8. The air pipes 9 drive the suction cups 10 and the connecting frame 11 to move downward. The connecting frame 11 drives the support plate 14 to move downward through the second elastic telescopic rod 12. When the lower side of the support plate 14 contacts the frame 1, the support plate 14 stops moving. The fixed part of the second elastic telescopic rod 12 continues to move and its telescopic end gradually retracts (during this process, the limiting rod 16 is always located in the limiting groove of the telescopic part of the second elastic telescopic rod 12).

[0058] During the gradual retraction of the extension end of the second elastic telescopic rod 12, when the suction cup 10 comes into contact with the metal part, the two are squeezed against each other, causing the suction cup 10 to gradually deform and fit against the adjacent area of ​​the metal part. At this time, the air pump starts and draws the gas from the upper chamber of the air pipe 9, causing the piston plate 901 to move upward and compress the first spring 902. The air pressure in the lower chamber of the air pipe 9 decreases and generates an upward force on the metal part until the suction cup 10 can no longer deform. Then the air pipe 9 stops moving, and the linear slide group 5 stops driving the fixed plate 6 to move downward.

[0059] During the process of the air pump drawing gas from the air pipe 9, as the piston plate 901 moves upward, the air pressure in the lower chamber of the air pipe 9 and the fourth elastic telescopic rod 21 decreases. The telescopic end of the fourth elastic telescopic rod 21 retracts and drives the arc frame 22 to move in the axial direction of the air pipe 9, so that the third elastic telescopic rod 15 is no longer connected to the air pipe 9.

[0060] During the deformation of the suction cup 10, the air tube 9 drives the third elastic telescopic rod 15 and the fourth elastic telescopic rod 21 to move downward. The third elastic telescopic rod 15 drives the adjusting block 1901 to move synchronously through the sealing frame 19. The fourth elastic telescopic rod 21 and the arc frame 22 move downward synchronously. When the adjusting block 1901 contacts the trapezoidal block 18, the trapezoidal block 18 squeezes the adjusting block 1901, causing the adjusting block 1901 to drive the sealing frame 19 to move and stretch the tension spring 20 until the air tube 9 stops moving. Then the sealing frame 19 stops moving and seals the air inlet of the third elastic telescopic rod 15.

[0061] As the air pump continues to draw gas from the air pipe 9, the piston plate 901 continues to move upward and compress the first spring 902. When the piston plate 901 contacts the annular protrusion inside the air pipe 9, the piston plate 901 stops moving, and the air pressure in the lower chamber of the air pipe 9 no longer changes. The air pump stops drawing gas from the upper chamber of the air pipe 9 and keeps its internal air pressure constant. The suction cup 10 completes the fixation of the metal part. The linear slide group 5 drives the fixing plate 6 and its parts to move upward. The suction cup 10 drives the metal part to move synchronously. The extension end of the second elastic telescopic rod 12 extends and resets. When the fixing plate 6 moves to the specified height, the linear slide group 5 drives the fixing plate 6 to move backward and reset, so that the metal plate moves above the upper mold 3. Then, the linear slide group 5 drives its parts to move downward through the fixing plate 6. When the metal plate contacts the upper mold 3, the air pump disconnects from the air pipe 9, so that the outer... The gas enters the upper chamber of the gas pipe 9, and the first spring 902 pushes the piston plate 901 downward to reset, causing the suction cup 10 to release the metal plate and reset. Then, the linear slide group 5 moves upward and forward again to move out from between the upper mold 3 and the lower mold 4. The frame 1 activates the induction heater inside to heat the upper mold 3 and the lower mold 4. At the same time, the telescopic end of the hydraulic push rod 2 drives the upper mold 3 to move downward to cooperate with the lower mold 4 to perform hot pressing and shaping of the metal part. After the shaping is completed, the hydraulic push rod 2 drives the upper mold 3 to reset. The linear slide group 5 repeats the above process of fixing the metal part to re-fix the metal part and take it out from the lower mold 4. Then, the metal part is moved to the storage rack of the frame 1. Then, the above process is repeated to shape other metal parts. After the shaping of this batch of metal parts is completed, the linear slide group 5 drives the parts on it to reset to the initial state.

[0062] During the upward movement of the metal part by the suction cup 10, if the suction cup 10 is damaged, resulting in a reduced seal between it and the metal part, outside air gradually enters the lower chamber of the air pipe 9 during the process of the suction cup 10 fixing the metal part. The air pressure in the lower chamber of the air pipe 9 and the fourth elastic telescopic rod 21 gradually recovers. The telescopic end of the fourth elastic telescopic rod 21 drives the arc frame 22 to reset, so that the third elastic telescopic rod 15 is connected to the air pipe 9 (at this time, the sealing frame 19 seals the air inlet of the third elastic telescopic rod 15). The air pump draws gas from the third elastic telescopic rod 15, and the telescopic end of the third elastic telescopic rod 15 extends and drives the limiting rod 16 to move synchronously, so that the limiting rod 16 separates from the limiting groove on the second elastic telescopic rod 12. The torsion spring 13 drives the support plate 14 to rotate 90° clockwise through the second elastic telescopic rod 12. Figure 5 The rotation direction of the middle support plate 14 is used as a reference (viewed from top to bottom), so that the support plate 14 swings to the bottom of the metal part, supporting the metal part from below, so that the metal part receives sufficient support force, and avoids it from sliding or even falling off during transportation due to the reduction of fixing force, which would affect the normal production of the metal part.

[0063] During the process of the linear slide group 5 moving the fixed plate 6 downward to place the metal plate into the lower mold 4, as the support plate 14 moves downward, after the support plate 14 contacts the reset block 141, the support plate 14 rotates in the opposite direction and resets under the pressure of the reset block 141. The support plate 14 drives the second elastic telescopic rod 12 to rotate synchronously and causes the torsion spring 13 to store force. When the air pump is turned off, the telescopic end of the third elastic telescopic rod 15 drives the limit rod 16 to reset, so that the limit rod 16 enters the limit groove of the second elastic telescopic rod 12 to complete the limit again. After the placement is completed, the staff replaces the damaged suction cup 10, and then repeats the above process to continue to shape the metal parts.

[0064] Since the shape of the existing metal parts is not flat, the surface of the metal parts has protrusions and depressions. After the metal casting is completed, the shrinkage deformation of the metal parts will change the position of the protrusions and depressions. This will cause the protrusions and depressions on the metal parts to be misaligned with the corresponding positions on the mold when the metal parts are placed, which will affect the shaping effect of the metal parts and may easily lead to damage to the mold.

[0065] Furthermore, such as Figure 3 , Figure 4 and Figure 9 As shown, it also includes: a vibration assembly, the same number as the number of air tubes 9, all set on the frame 1, used to drive the air tubes 9 to shake. The vibration assembly includes: a support frame 23, fixed to the frame 1, with a vibration plate 24 fixed to the support frame 23; a transmission rod 25, fixed to the extension part of the first elastic telescopic rod 7, with the vibration plate 24 having a wave surface, the wave surface of the vibration plate 24 being used to push the extension end of the transmission rod 25 to move.

[0066] The above solution provides a method to shake the metal part when there is a protrusion on the surface of the metal part (the following description assumes that the metal part only has a protrusion), thereby further adjusting the position of the metal part and ensuring that the position of the protrusion of the metal part fits with the corresponding position of the mold. In this embodiment, four vibration plates 24 are provided on the support frame 23, and two vibration plates 24 are grouped together. The two vibration plates 24 are located on both sides of the axis of the adjacent first elastic telescopic rod 7, and the upper part of the two vibration plates 24 in the same group is inclined outward to guide the transmission rod 25, so that the transmission rod 25 can enter between the two vibration plates 24 in the same group and move along the wave surface of the vibration plate 24. In this embodiment, the first elastic telescopic rod 7 has two symmetrically distributed transmission rods 25, so that the extension end of the first elastic telescopic rod 7 is subjected to uniform force.

[0067] Workflow: This section uses the movement direction of the linear slide group 5 on the right and its components as a reference. After the linear slide group 5 moves the fixed plate 6 backward to the designated position (at this time, the metal part moves above the lower mold 4), the linear slide group 5 moves the fixed plate 6 downward. The fixed plate 6, through the first elastic telescopic rod 7, drives the transmission rod 25 downward. As the transmission rod 25 moves downward, it gradually approaches the two adjacent vibrating plates 24 until the metal part approaches the lower mold 4. Then, the transmission rod 25 enters between the two adjacent vibrating plates 24. The operator turns off the air pump, allowing the metal part to fall into the lower mold 4. The transmission rod 25 moves downward along the wave surface of the vibrating plate 24, causing the transmission rod 25 to extend and retract the first elastic telescopic rod 7. The part moves left and right continuously, causing the first elastic telescopic rod 7 to move synchronously with the air pipe 9 through the connecting ring 8. This causes the suction cup 10 to squeeze the metal part through friction (during this process, the suction cup 10 exerts a downward squeezing force on the metal part), thereby causing the metal part to sway left and right. This makes the protrusion on the metal part correspond to the lower mold 4. When the protrusion on the metal part is aligned with the corresponding position on the lower mold 4, the metal part is stuck and no longer moves. This continues until the transmission rod 25 separates from the wave surface of the vibration plate 24. Then, the linear slide group 5 stops driving the fixed plate 6 to move downward, and the suction cup 10 stops swaying, completing the final adjustment of the position of the metal part. The linear slide group 5 then drives the parts on it to move in the opposite direction to reset. After that, the hydraulic push rod 2 drives the upper mold 3 to move downward to shape the metal part.

[0068] Furthermore, such as Figure 5 and Figure 10 As shown, it also includes: a fixing component, the same number as the first elastic telescopic rods 7, respectively set on adjacent first elastic telescopic rods 7, used to limit the height of the air tube 9. The fixing component includes: a squeezing block 26, fixed to the telescopic part of the first elastic telescopic rod 7, a connecting ring 8 slidably connected to the air tube 9, the squeezing block 26 is provided with an inclined surface, a second spring 27 is fixedly connected between the connecting frame 11 and the connecting ring 8; a connecting plate 28, fixed to the adjacent connecting frame 11, the connecting plate 28 is slidably connected to an L-shaped plate 29, the L-shaped plate 29 is located on the moving path of the adjacent squeezing block 26, the support frame 23 is located on the moving path of the adjacent L-shaped plate 29, and a third spring 30 is fixedly connected between the L-shaped plate 29 and the connecting plate 28.

[0069] The above solution provides a way to reduce the downward squeezing force on the metal parts when the metal plate is shaken; the inclined surface of the squeezing block 26 is used to squeeze the L-shaped plate 29. In this embodiment, the connecting ring 8 and the air pipe 9 can slide relative to each other. The second spring 27 is used to push the air pipe 9 to move downward relative to the connecting ring 8 through the connecting frame 11; the third spring 30 is always in a compressed state to maintain the stability of the L-shaped plate 29.

[0070] Workflow: During the process of placing the metal part into the lower mold 4, as the first elastic telescopic rod 7 moves the air pipe 9 downward through the connecting ring 8, the first elastic telescopic rod 7 moves the extrusion block 26 downward. The air pipe 9 moves the connecting plate 28 downward through the connecting frame 11. The connecting plate 28 moves the L-shaped plate 29 and the third spring 30 downward until the L-shaped plate 29 contacts the support frame 23. Then the L-shaped plate 29 stops moving downward (at this time, the transmission rod 25 is about to enter the wave area of ​​the vibrating plate 24). The connecting plate 28 stops moving downward, and the connecting frame 11 and the air pipe 9 stop moving downward. At this time, the air pump is turned off, the metal part falls into the lower mold 4, and the downward extrusion force of the suction cup 10 on the metal part no longer increases, so as to avoid the suction cup 10 exerting too much extrusion force on the metal part, which would prevent the metal part from moving and affect the adjustment of the position of the metal part.

[0071] As the connecting ring 8 drives the parts on it to continue moving downwards, the second spring 27 is gradually compressed. The transmission rod 25 drives the extension end of the first elastic telescopic rod 7 to shake and repeat the above process to adjust the position of the metal plate. When the inclined surface of the pressing block 26 contacts the L-shaped plate 29, the pressing block 26 pushes the L-shaped plate 29 to the left and compresses the third spring 30 until the lower side of the L-shaped plate 29 separates from the support frame 23. Then, the second spring 27 pushes the air pipe 9 downwards through the connecting frame 11 (during this process, the L-shaped plate 29 will not move to the lower side of the support frame 23, and the adjacent side of the L-shaped plate 29 and the support frame 23 are in contact), which increases the squeezing force of the suction cup 10 on the metal part, completing the final fixation of the metal part. After that, the linear slide group 5 drives the parts on it to move in the opposite direction to reset.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
