Description

Technical Field

[0001] This application relates to the field of switch technology, and in particular to a micro switch spring feeding device. Background Technology

[0002] Various switches are used in automobiles, and each switch typically has multiple buttons. A micro switch is one such type of switch. A micro switch consists of an upper and lower mating body, with a limiting groove between them. Both the upper and lower mating bodies have limiting posts located within the limiting groove. A spring is installed within the limiting groove, and both ends of the spring are inserted into the limiting posts to provide a reset function upon pressing.

[0003] During the production of micro switches, the upper and lower plug-in bodies need to be plugged in before the spring is installed to ensure stable installation. However, since both ends of the spring need to be inserted into the corresponding limit posts of the upper and lower plug-in bodies to prevent the spring from detaching from the limit posts and limit slots during use, this spring installation method is complex. Generally, mechanical installation cannot be used to install the spring, and manual placement is required. However, manual placement not only consumes manpower and resources, but also, under long working hours, omissions may occur, which can easily lead to the spring not being accurately aligned with the limit posts, affecting subsequent processing. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a micro switch spring feeding device.

[0005] The micro-switch spring feeding device provided in this application adopts the following technical solution: A micro-switch spring feeding device includes a conveyor belt on one side, with conveyor stations spaced at preset intervals on the conveyor belt, where upper and lower insert bodies are stored; it includes a mounting frame, a gripper assembly, an opening and closing assembly, a horizontal movement assembly, and opening and closing grippers; the mounting frame is located on one side of the conveyor belt, and the horizontal movement assembly is located on one side of the mounting frame, providing horizontal drive; the gripper assembly is connected to the drive end of the horizontal movement assembly and is located directly above the mounting frame; a vibratory feeder is externally connected to the lower part of the mounting frame; the opening and closing assembly is connected to the mounting frame, providing opening and closing for the upper and lower insert bodies; the opening and closing grippers are connected to the drive end of the opening and closing assembly.

[0006] By adopting the above technical solution, when the conveyor belt sequentially transports the conveyor stations to the opening and closing grippers, the opening and closing grippers move to the conveyor station under the drive of the opening and closing components, and pull the upper section of the insertion body along the conveyor station. The gripper components simultaneously clamp the springs conveyed by the vibratory feeder, and then move them above the conveyor station through the horizontal moving components to place the springs. The springs fall from the opening and closing grippers between the upper section of the insertion body and the lower section of the opening and closing body. The separation of the upper section of the insertion body and the lower section of the insertion body opens up the space for placing the springs. After the springs are placed, the upper section of the insertion body is pushed to the lower section of the insertion body, so that the limiting post and the spring gradually approach each other until they are inserted, so as to ensure accurate and stable installation.

[0007] Optionally, the gripper assembly includes a lifting drive chain and a pneumatic gripper; the lifting drive chain is connected to the drive end of the horizontal movement component, and the pneumatic gripper is installed on the lifting end of the lifting drive chain.

[0008] By adopting the above technical solution, under the clamping and releasing action of the pneumatic gripper, and through the linkage between the horizontal moving component and the lifting drive chain, the spring can stably feed material from the discharge end of the vibratory plate to the transmission station.

[0009] Optionally, the opening and closing assembly includes a fixed frame, an opening and closing drive unit, a guide unit, and a connecting unit; the fixed frame is mounted on the conveyor belt and the mounting frame; the guide unit is mounted on the fixed frame and the mounting frame, and an extension cavity is provided inside the guide unit, with a guide port communicating with the outside on the side of the extension cavity; the connecting unit is located inside the extension cavity; the opening and closing drive unit is mounted on the outer wall of the guide unit, and the drive end extends through the guide port into the extension cavity and connects with the connecting unit; the opening and closing gripper is connected to the connecting unit.

[0010] By adopting the above technical solution, the opening and closing drive unit drives the connecting part to move along the guide opening, so that the opening and closing gripper follows the connecting part. The opening and closing gripper moves to the upper section of the transmission station and, after being locked with the upper section of the insertion body, the opening and closing drive unit drives the connecting part and the opening and closing gripper to move towards the guide, so that the upper section of the insertion body is pulled towards the guide, thereby achieving stable driving of the opening and closing gripper.

[0011] Optionally, the guide opening direction is provided with an arc-shaped bend.

[0012] By adopting the above technical solution, the opening and closing gripper moves downward along the arc surface, so that the opening and closing gripper enters the upper section of the mating body from top to bottom. Then, it moves along a fixed horizontal direction, so that the opening and closing gripper moves the upper section of the mating body along the transmission station, while the lower section of the mating body is fixed on the transmission station, thus achieving the effect of separating the upper section of the mating body from the lower section of the mating body.

[0013] Optionally, the drive end of the opening and closing drive unit is connected to a mating part. The mating part has an adapter groove in the vertical direction on the side near the guide port. An adapter block is slidably connected in the adapter groove. The adapter block extends out to form a connecting post. The connecting post passes through the guide port and connects with the connecting block.

[0014] By adopting the above technical solution, the connecting column moves along the arc-shaped wall of the guide opening, and simultaneously pushes the adapter block to move along the adapter groove, so that the opening and closing drive unit can stably provide the driving effect at the arc-shaped bend. Without additional drive, the opening and closing gripper can move along the arc-shaped bend of the guide opening through the connecting block and the connecting column.

[0015] Optionally, the opening and closing gripper includes a gripper rod, a first opening and closing frame, and a second opening and closing frame; both the first and second opening and closing frames are mounted on the gripper rod, and the gripper rod extends into the extension cavity and connects to the connecting block; there is a gap between the first and second opening and closing frames, and a spring is inserted into the upper and lower insertion parts through the gap.

[0016] By adopting the above technical solution, the placement position and path of the spring can be defined by the gap, so that when the spring is released from the gripper assembly, it can fall into the space between the upper and lower mating parts along the gap, thus avoiding the spring placement position from being offset.

[0017] Optionally, the first and second opening and closing frames adopt a Z-shaped frame, and a reset protrusion is provided on one side of the gripper bar.

[0018] By adopting the above technical solution, the Z-shaped frame allows the upper section of the fitting to be locked on the side of the Z-shaped frame, so that the Z-shaped frame can stably pull the upper section of the fitting when it moves. After the Z-shaped frame separates from the upper section of the fitting, the reset protrusion contacts the upper section of the fitting and pushes the upper section of the fitting to reset, so that the upper section of the fitting and the lower section of the fitting are re-inserted. The corresponding limit post is synchronously inserted with the spring, realizing the accurate feeding function of the spring.

[0019] Optionally, the first and second opening and closing frames are provided with inclined openings; an installation shaft is provided in the inclined opening, and an inclined plate is movably connected to the installation shaft; an elastic part is provided between the inclined plate and the installation shaft; a pushing part is provided at the bottom of the pneumatic gripper, and when the pneumatic gripper moves to the lower position, the pushing part contacts the inclined plate.

[0020] By adopting the above technical solution, the pneumatic gripper and the spring descend to the inclined plate. The pushing part extends the pneumatic gripper and contacts the inclined plate first, thus pushing the inclined plate to rotate along the mounting shaft, thereby tilting the inclined plate and expanding the placement area of ​​the spring. When the pneumatic gripper opens, the spring contacts the inclined plate, allowing the spring to roll along the inclined plate into the gap, achieving a more stable and accurate spring placement effect.

[0021] Optionally, the tilting direction of the tilting plate of the first opening and closing frame is opposite to that of the tilting plate of the second opening and closing frame, and the mounting shaft is located on the side of the corresponding tilting plate away from the other tilting plate.

[0022] By adopting the above technical solution, the inclined plates on the first and second opening and closing frames can tilt relative to each other towards the gap, ensuring the stable rolling and falling of the spring. The mounting shaft is located on the side of the inclined plate away from the gap, ensuring that the inclined plate can only tilt towards the opening, thus guaranteeing the accuracy of the tilt position. Optionally, the pushing part includes a pushing cylinder, a pushing rod, and a pushing spring; the pushing cylinder is installed at the clamping end of the pneumatic gripper, the pushing rod is inserted into the pushing cylinder and extends and retracts along the pushing cylinder; the pushing spring is located inside the pushing cylinder, with one end connected to the pushing rod and the other end connected to the pushing cylinder, the pushing rod extends outward under the action of the pushing spring and extends out of the bottom of the pneumatic gripper; the elastic force of the pushing spring is greater than the elastic force of the elastic part.

[0023] By adopting the above technical solution, when the pneumatic gripper drives the push rod to move down, the push rod can press the inclined plate down and tilt it. When the pneumatic gripper releases the spring, the spring that falls on the inclined plate can roll towards the gap with the inclined surface. The position of the spring is defined by the gap, and the feeding is completed. This can ensure the accurate pushing and tilting of the inclined plate, make the spring placement accurate, and make the feeding more stable.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. When the conveyor belt sequentially transports the conveyor stations to the opening and closing grippers, the opening and closing grippers move to the conveyor station under the drive of the opening and closing assembly, and pull the upper section of the insertion body along the conveyor station. The gripper assembly simultaneously clamps the spring conveyed by the vibratory feeder, and then moves to the top of the conveyor station through the horizontal moving assembly to place the spring. The spring falls from the opening and closing grippers between the upper section of the insertion body and the lower section of the opening and closing body. The separation of the upper section of the insertion body and the lower section of the insertion body opens the placement space for the spring. After the spring is placed, the upper section of the insertion body is pushed to the lower section of the insertion body, so that the limiting post and the spring gradually approach until they are inserted, so as to ensure the accuracy and stability of the automatic installation of the spring. 2. Under the clamping and releasing action of the pneumatic gripper, the spring can stably feed material from the discharge end of the vibratory plate to the transmission station through the linkage of the horizontal moving component and the lifting drive chain. 3. The opening and closing drive unit drives the connecting part to move along the guide opening, so that the opening and closing gripper follows the connecting part. The opening and closing gripper moves to the upper section of the transmission station and, after locking with the upper section of the insertion body, the opening and closing drive unit drives the connecting part and the opening and closing gripper to move towards the guide, so that the upper section of the insertion body is pulled towards the guide, thereby achieving stable driving of the opening and closing gripper. 4. The opening and closing grippers move downward along the arc surface, so that the opening and closing grippers enter the upper section of the mating body from top to bottom. Then, they move along a fixed horizontal direction, so that the opening and closing grippers move the upper section of the mating body along the transmission station, while the lower section of the mating body is fixed on the transmission station, thus achieving the effect of separating the upper section of the mating body from the lower section of the mating body.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 This application will be described in further detail below.

[0032] This application discloses a micro-switch spring feeding device.

[0033] A micro-switch spring feeding device, applied to reference Figure 1The micro switch shown consists of an upper connector 1 and a lower connector 2. A limiting groove 11 is formed between the upper connector 1 and the lower connector 2. Both the upper connector 1 and the lower connector 2 are provided with limiting posts 3 at the limiting groove 11. A spring 12 is provided in the limiting groove 11. The two ends of the spring 12 are inserted into the limiting posts 3 to provide a press-to-reset function.

[0034] A conveyor belt 5 is provided on one side of the spring 12 feeding device. The conveyor belt 5 is provided with conveying stations 51 at preset intervals. The upper section of the fitting body 1 and the lower section of the fitting body 2 are stored on the conveyor belt 5. The conveyor belt 5 conveys at intervals, and the conveying distance is the interval between the conveying stations 51, so that each conveying station 51 can move along the conveyor belt to the spring 12 feeding device.

[0035] refer to Figure 2 As shown, the micro switch spring 12 feeding device of this application includes a mounting frame 6, a gripper assembly 7, a horizontal movement assembly 9, an opening and closing assembly 8, and an opening and closing gripper 10. The mounting frame 6 is located on one side of the conveyor belt 5, and the horizontal movement assembly 9 is located on one side of the mounting frame 6, providing horizontal drive. The mounting frame 6 is the overall support of the entire spring 12 feeding device, while the horizontal movement assembly 9 provides the drive for horizontal movement. The horizontal movement assembly 9 can adopt an existing conveyor chain structure or a screw and nut structure to provide a stable conveying effect.

[0036] The gripper assembly 7 is connected to the drive end of the horizontal moving assembly 9 and is located directly above the mounting frame 6. The gripper assembly 7 can move horizontally under the drive of the horizontal moving assembly 9, thereby moving directly above the mounting frame 6 or directly above the transmission station 51 of the conveyor belt 5. The gripper assembly 7 is provided to grip the spring 12 to be installed and place it at the upper section insertion body 1 and the lower section insertion body 2 on the transmission station 51.

[0037] The mounting frame 6 is connected to the conveying end of the vibratory feeder 4. The vibratory feeder 4 is an existing structure outside this device. It contains the springs 12 that need to be installed and is conveyed to the bottom of the mounting frame 6 by vibration. The springs 12 are then picked up by the gripper assembly 7.

[0038] The opening and closing assembly 8 is connected to the mounting bracket 6, providing the opening and closing drive for the upper section of the mating body 1 and the lower section of the mating body 2. The opening and closing gripper 10 is connected to the drive end of the opening and closing assembly 8. When the transmission station 51 moves to the opening and closing assembly 8, the opening and closing assembly 8 drives the opening and closing gripper 10 to pull the upper section of the mating body 1 along the transmission station 51, thereby separating the upper section of the mating body 1 and the lower section of the mating body 2, and separating the limiting groove 11, thereby increasing the storage space of the spring 12. Subsequently, the gripper assembly 7 can clamp the spring 12 and place it in the limiting groove 11.

[0039] A sensor can be installed at the opening and closing component 8 to detect whether the transmission station 51 has accurately reached the opening and closing component 8. After the detection result confirms that it has arrived, the opening and closing component 8 drives the opening and closing gripper 10 to pull the upper insertion body 1.

[0040] Specifically, when the conveyor belt 5 sequentially transports the conveyor station 51 to the opening and closing gripper 10, the opening and closing gripper 10 moves to the conveyor station 51 under the drive of the opening and closing component 8, and pulls the upper section of the insertion body 1 along the conveyor station 51. The gripper component 7 simultaneously clamps the spring 12 transported by the vibratory plate 4, and moves to above the conveyor station 51 through the horizontal moving component 9. The gripper component 7 releases the spring 12, causing the spring 12 to fall from the opening and closing gripper 10 between the upper section of the insertion body 1 and the lower section of the opening and closing body. The opening and closing gripper 10 limits the spring 12 to prevent it from shifting. Then, the opening and closing gripper 10 is driven by the opening and closing component 8 to push the upper section of the insertion body 1 to the lower section of the insertion body 2, so that the limiting post 3 of the upper section of the insertion body 1 and the lower section of the insertion body 2 gradually connects with the spring 12 until the spring 12 is pressed and limited on the upper section of the insertion body 1 and the lower section of the insertion body 2. The opening and closing gripper 10 then disengages from the conveyor station 51, completing the assembly.

[0041] This method allows the upper section of the connector 1 to be separated from the lower section of the connector 2, thereby opening the placement space for the spring 12. After the spring 12 is placed, the upper section of the connector 1 is pushed to the lower section of the connector 2, so that the limiting post 3 and the spring 12 gradually approach each other until they are connected, thus ensuring the accuracy and stability of the automatic installation of the spring 12.

[0042] Further reference Figure 2 As shown, the gripper assembly 7 includes a lifting drive chain 71 and a pneumatic gripper 72. The lifting drive chain 71 is connected to the drive end of the horizontal moving assembly 9, allowing the lifting drive chain 71 to move between the transmission station 51 and the mounting frame 6 under the drive of the horizontal moving assembly 9. The pneumatic gripper 72 is installed at the lifting end of the lifting drive chain 71. Therefore, when the pneumatic gripper 72 moves horizontally with the lifting drive chain 71, it moves to the mounting frame 6, where the lifting drive chain 71 drives the pneumatic gripper 72 to descend to the discharge end of the vibratory feeder 4 and clamp the spring 12. After the drive chain 71 pulls the pneumatic gripper 72 upward, it moves to above the transmission station 51 via the horizontal moving component 9. The lifting drive chain 71 then pushes the pneumatic gripper 72 to the opening and closing gripper 10, so that after the pneumatic gripper 72 is released, the spring 12 is placed between the upper section of the insertion body 1 and the lower section of the insertion body 2 from the opening and closing gripper 10. Therefore, under the clamping and releasing action of the pneumatic gripper 72, through the linkage of the horizontal moving component 9 and the lifting drive chain 71, the spring 12 can stably feed material from the discharge end of the vibratory plate 4 to the transmission station 51.

[0043] In some embodiments, reference Figure 3 and Figure 4As shown, the opening and closing assembly 8 includes a fixed frame 81, an opening and closing drive part 82, a guide part 83, and a connecting part 84. The fixed frame 81 is installed on one side of the conveyor belt 5 and is connected to the non-conveying end of the conveyor belt 5, so that the position of the fixed frame 81 is fixed, ensuring that the conveying station 51 can be accurately moved to the opening and closing assembly 8.

[0044] The guide part 83 is mounted on the fixed frame 81 and the mounting frame 6. The mounting frame 6 provides support for the guide part 83, and the fixed frame 81 provides positioning for the guide part 83.

[0045] The guide section 83 has an extension cavity inside, and the side of the extension cavity has a guide port 831 that communicates with the outside. The guide section 83 can be a rectangular guide box with an extension cavity inside. The end of the extension cavity near the conveyor belt 5 is a cavity for the opening and closing gripper 10 to be inserted, and the guide port 831 is located on one side of the extension cavity.

[0046] The connecting part 84 is located inside the extension cavity. The connecting part 84 may be a connecting frame, which is used to provide a connection with the opening and closing gripper 10. Therefore, the opening and closing gripper 10 is connected to the connecting part 84 when it is inserted into the extension cavity.

[0047] The opening and closing drive unit 82 is installed on the outer wall of the guide part 83, and the drive end extends through the guide port 831 into the extension cavity and connects with the connecting part 84. The opening and closing drive unit 82 provides drive for the connecting part 84 in the extension cavity, so that the connecting part 84 can drive the opening and closing gripper 10 to move along the guide port 831. During the movement, the opening and closing gripper 10 moves to the upper insertion body 1, or is pulled from the upper insertion body 1 towards the guide part 83, so as to achieve stable drive of the opening and closing gripper 10.

[0048] The opening and closing drive unit 82 can be a magnetically coupled rodless cylinder to stably drive the connecting part 84 and the opening and closing gripper 10 to move.

[0049] Specifically, the opening and closing drive unit 82 drives the connecting part 84 to move along the guide port 831, causing the opening and closing gripper 10 to move with the connecting part 84. The opening and closing gripper 10 moves to the upper section of the insertion body 1 at the transmission station 51, and after it is locked with the upper section of the insertion body 1, the opening and closing drive unit 82 drives the connecting part 84 and the opening and closing gripper 10 to move towards the guide part 83, so that the upper section of the insertion body 1 is pulled towards the guide part 83, thereby achieving stable driving of the opening and closing gripper 10.

[0050] Further reference Figure 4As shown, the guide opening 831 has an arc-shaped bend in its opening direction. The direction of the arc-shaped bend is from the original X-axis to the fourth quadrant, forming a Z-shaped path. The function of the arc-shaped bend is to allow the opening and closing gripper 10 to move along the arc-shaped bend of the guide opening 831, changing the direction of the opening and closing gripper 10. When the opening and closing gripper 10 moves along the arc-shaped bend, it will first move along a fixed horizontal direction. After moving, the opening and closing gripper 10 moves to the arc-shaped bend, so that the opening and closing gripper 10 moves downward along the arc surface, so that the opening and closing gripper 10 enters the upper section of the fitting body 1 from top to bottom. Then it moves along a fixed horizontal direction, so that the opening and closing gripper 10 moves the upper section of the fitting body 1 along the transmission station 51, while the lower section of the fitting body 2 is fixed on the transmission station 51, realizing the effect of separating the upper section of the fitting body 1 and the lower section of the fitting body 2.

[0051] Furthermore, refer to Figure 4 and Figure 5 As shown, the driving end of the opening and closing drive unit 82 is connected to a mating part 821. The mating part 821 has a vertically oriented adapter groove 822 on the side near the guide opening 831. The mating part 821 can be a mating block, which is located outside the opening and closing drive unit 82 and is not inserted into the guide opening 831. The adapter groove 822 can be a T-shaped groove or an I-shaped groove. An adapter block 823 is slidably connected in the adapter groove 822. The shape of the adapter block 823 matches the adapter groove 822. The adapter block 823 extends into a connecting post 824. The connecting post 824 can be a circular column structure, which can reduce the contact area with the guide opening 831 and ensure that the connecting post 824 can reduce frictional resistance when moving along the guide opening 831. The connecting post 824 passes through the guide opening 831 and is connected to the connecting block.

[0052] When the engaging part 821 is driven by the opening and closing drive part 82, the moving direction is horizontal. During the movement, when the adapter block 823 and the connecting post 824 move to the arc-shaped bend of the guide opening 831, they cannot move directly. The connecting post 824 moves along the arc-shaped wall of the guide opening 831, and simultaneously pushes the adapter block 823 to move along the adapter groove 822. This allows the opening and closing drive part 82 to stably provide the driving effect at the arc-shaped bend. Without additional driving, the opening and closing gripper 10 can move along the arc-shaped bend of the guide opening 831 through the connecting block and the connecting post 824.

[0053] In some embodiments, reference Figure 6 and Figure 7As shown, the opening and closing gripper 10 includes a gripper rod 101, a first opening and closing frame 102, and a second opening and closing frame 103. The first opening and closing frame 102 and the second opening and closing frame 103 are both installed on the gripper rod 101, and the gripper rod 101 extends into the extension cavity and connects to the connecting block. There is a gap 104 between the first opening and closing frame 102 and the second opening and closing frame 103. The spring 12 is placed into the upper section of the insert body 1 and the lower section of the insert body 2 through the gap 104. The gap 104 can limit the placement position and placement path of the spring 12, so that when the spring 12 is lowered from the gripper assembly 7, it can fall into the space between the upper section of the insert body 1 and the lower section of the insert body 2 along the gap 104, thus avoiding the situation where the placement position of the spring 12 is offset.

[0054] Further reference Figure 3 and Figure 4 As shown, the first opening and closing frame 102 and the second opening and closing frame 103 adopt a Z-shaped frame. The Z-shaped frame allows the upper section of the insertion body 1 to be locked on the side of the Z-shaped frame, so that when the Z-shaped frame moves, it can stably pull the upper section of the insertion body 1 to move. When moving in the other direction away from the upper section of the insertion body 1, the Z-shaped frame can directly detach from the upper section of the insertion body 1. The gripper bar 101 is provided with a reset protrusion 1011 on the side near the first opening and closing frame 102 and the second opening and closing frame 103. After the Z-shaped frame separates from the upper section of the insertion body 1, the reset protrusion 1011 contacts the upper section of the insertion body 1 and pushes the upper section of the insertion body 1 to reset, so that the upper section of the insertion body 1 and the lower section of the insertion body 2 are re-inserted. The corresponding limiting post 3 is simultaneously inserted with the spring 12, realizing the accurate feeding function of the spring 12.

[0055] Specifically, before the opening and closing gripper 10 passes through the arc-shaped bend of the guide port 831, the reset protrusion 1011 contacts the upper section of the insert body 1. After the opening and closing gripper 10 passes through the arc-shaped bend, the reset protrusion 1011 completes the reset with the upper section of the insert body 1 and separates from it.

[0056] Furthermore, refer to Figure 6 and Figure 7 As shown, the first opening and closing frame 102 and the second opening and closing frame 103 are provided with inclined openings 105; the inclined opening 105 is provided with a mounting shaft 107, and an inclined plate 106 is movably connected to the mounting shaft 107. The inclined plate 106 can rotate along the mounting shaft 107, thereby achieving the tilting effect.

[0057] An elastic part 108 is provided between the inclined plate 106 and the mounting shaft 107. The elastic part 108 can be a torsion spring. One end of the torsion spring is wrapped around the mounting shaft 107 and connected to the wall of the inclined opening 105, and the other end is connected to the inclined plate 106, so as to provide elastic force for the inclined plate 106 to rotate along the mounting shaft 107.

[0058] The pneumatic gripper 72 has a pushing part 73 at its bottom. When the pneumatic gripper 72 moves to the lower position, the pushing part 73 contacts the inclined plate 106. After the pneumatic gripper 72 clamps the spring 12 and moves above the opening and closing gripper 10, the lifting drive chain 71 drives the pneumatic gripper 72 and the spring 12 to descend to the inclined plate 106. The pushing part 73 extends out of the pneumatic gripper 72 and contacts the inclined plate 106 first, thus pushing the inclined plate 106 to rotate along the mounting shaft 107, thereby tilting the inclined plate 106 and expanding the placement area of ​​the spring 12. When the pneumatic gripper 72 opens, the spring 12 contacts the inclined plate 106, allowing the spring 12 to roll along the inclined plate 106 into the spacer 104, achieving a more stable and accurate placement effect of the spring 12.

[0059] The tilting plates 106 of the first opening and closing frame 102 and the second opening and closing frame 103 are tilted in opposite directions, and the mounting shaft 107 is located on the side of the tilting plate 106 away from the partition opening 104. This allows the tilting plates 106 on the first opening and closing frame 102 and the second opening and closing frame 103 to tilt relative to each other towards the partition opening 104 when the pushing part 73 pushes the tilting plate 106, so as to ensure the stable rolling and falling of the spring 12. The mounting shaft 107 is located on the side of the tilting plate 106 away from the partition opening 104, so that the tilting plate 106 can only tilt towards the tilt opening 105, ensuring the accuracy of the tilting position.

[0060] refer to Figure 7 and Figure 8 As shown, when the pusher 73 moves to both sides at the same height under the drive of the pneumatic gripper 72 to release the spring 12, the pusher 73 continuously moves towards the mounting shaft 107, thereby continuously pushing the tilting plate 106 to tilt. This allows the tilting angle of the tilting plate 106 to be adjusted as the pneumatic gripper 72 continuously opens, so that the spring 12 can roll more stably along the tilting surface of the tilting plate 106 to the spacer 104, thereby improving the feeding accuracy of the spring 12.

[0061] After the spring 12 is loaded, the pneumatic gripper 72 separates from the opening and closing gripper 10, and at the same time, the pushing part 73 separates from the inclined plate 106. At this time, the elastic force of the elastic part 108 causes the inclined plate 106 to return to its original position. This method can provide a certain degree of defective product detection. After the inclined plate 106 is reset, it extends horizontally to the interval opening 104, thus covering part of the interval opening 104 and preventing the spring 12 from falling off. If the spring 12 does not roll along the inclined plate 106 to the interval opening 104 for loading, the spring 12 will be blocked on the inclined plate 106 after the inclined plate 106 is reset. A detection structure can be set at the end of the conveyor belt 5 to facilitate the detection of whether the spring 12 remains on the inclined plate 106. Therefore, this method can also provide a barrier against defective products to improve the accuracy of defective product detection.

[0062] Further, refer to Figure 7 or Figure 8 As shown, the pushing part 73 includes a pushing cylinder 731, a pushing rod 732, and a pushing spring 733. The pushing cylinder 731 is installed at the clamping end of the pneumatic gripper 72. The pushing rod 732 is inserted into the pushing cylinder 731 and extends and retracts along the pushing cylinder 731. The pushing rod 732 is used to extend out of the pushing cylinder 731 and provide a pushing force to the inclined plate 106. The end of the pushing rod 732 may be rounded to reduce friction during pushing.

[0063] The push spring 733 is located inside the push cylinder 731, with one end connected to the push rod 732 and the other end connected to the push cylinder 731. The push rod 732 extends outward under the action of the push spring 733 and extends out of the bottom of the pneumatic gripper 72. The elastic force of the push spring 733 is greater than the elastic force of the elastic part 108, so that when the pneumatic gripper 72 moves above the inclined plate 106, the push rod 732 will contact the inclined plate 106 first because it extends out of the bottom of the pneumatic gripper 72. The elastic force of the push spring 733 is greater than the elastic force of the elastic part 108, that is, the elastic force of the push spring 733 is greater than the elastic force of the torsion spring. Therefore, the push rod 732 can press the inclined plate 106 down and tilt it, so that when the pneumatic gripper 72 releases the spring 12, the spring 12 that falls on the inclined plate 106 can roll with the inclined surface to the spacer opening 104. The spacer opening 104 limits the position of the spring 12, thus completing the loading.

[0064] When the pneumatic gripper 72 opens, the push rod 732 also moves synchronously toward the mounting shaft 107 to adjust the tilt angle of the tilting plate 106.

[0065] When the pneumatic gripper 72 needs to move to the discharge end of the vibratory plate 4 to clamp the spring 12, the pneumatic gripper 72 descends, causing the push rod 732 to contact the discharge end surface of the vibratory plate 4. This presses the push rod 732 into the push cylinder 731, compressing the push spring 733. After the pneumatic gripper 72 clamps the spring 12, it separates from the discharge end of the vibratory plate 4. The push spring 733 then pushes the push rod 732 out of the push cylinder 731, thus allowing the pneumatic gripper 72 to move freely. When the material moves above the gap 104 and is driven down by the lifting drive chain 71, the push spring 733 overcomes the elastic force of the elastic part 108 to push the inclined plate 106, causing the inclined plate 106 to tilt. The pneumatic gripper 72 releases the spring 12, and the spring 12 rolls along the inclined plate 106 into the gap 104. After the pneumatic gripper 72 completes the loading, it drives the push rod 732 to move upward, so that the inclined plate 106 is reset by the elastic force of the elastic part 108.
