Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of detection devices, and in particular to a device for detecting defective guide rods. Background Technology
[0002] The guide rod is a component on the water inlet valve of the washing machine. It contains a spring and an iron core, and is fitted onto a coil. When the coil is energized, the iron core compresses the spring under the influence of the energized coil. Because both the spring and the iron core are located on the guide rod, compressing the spring ensures that the iron core and spring do not shift during movement. However, during production, the springs may become entangled, resulting in multiple springs or no springs on the guide rod. Guide rods with multiple springs or no springs are defective and require inspection and rejection.
[0003] Existing technologies generally employ manual inspection methods. First, operators inspect the guide rods on the assembly line. Then, operators manually select guide rods that contain multiple springs or have no springs. Finally, these defective guide rods are placed in a defective guide rod box.
[0004] However, the above-mentioned manual inspection method requires operators to visually inspect and manually remove defective guide rods, which is a tedious operation and increases the labor intensity of the operators. Utility Model Content
[0005] This application provides a guide rod defect detection device, which can help reduce the labor intensity of operators.
[0006] This application provides a defective guide rod detection device, which adopts the following technical solution:
[0007] A defective guide rod detection device includes a worktable with a guide rail and a conveying mechanism for conveying the guide rod, the guide rail abutting against the guide rod; multiple first laser sensors for detecting the presence or absence of an iron core are mounted on the worktable; a gantry frame is fixedly connected to the worktable, a first sliding block is mounted on the gantry frame, a clamping mechanism for holding the guide rod is mounted on the first sliding block, and a driving mechanism for moving the first sliding block is mounted on the gantry frame; a recycling bin is mounted on the side of the worktable near the gantry frame; a second laser sensor is mounted on the worktable for detecting whether the clamping mechanism is clamping the guide rod; a detection mechanism for detecting the number of springs on the guide rod is mounted on the gantry frame; and a finished product bin is mounted on the worktable.
[0008] By adopting the above technical solution, when the guide rod needs to be detected, the guide rod is first conveyed to the designated position by the conveying mechanism, and then the guide rod is detected by the first laser sensor. When the first laser sensor does not detect the iron core, it is because the iron core has fallen into the guide rod, resulting in the first laser sensor not detecting the iron core. Therefore, there is no spring on the guide rod. Then, the clamping mechanism clamps the guide rod and drives it to separate from the guide rail. After the guide rod is separated from the guide rail, the driving mechanism drives the first sliding block to move above the recycling box. At this time, the second laser sensor detects the guide rod clamped by the clamping mechanism. When the second laser sensor does not detect the guide rod, the above clamping action is repeated until the second laser sensor detects the guide rod. When the sensor detects a guide rod, the clamping mechanism is released, allowing the guide rod to be moved into the recycling bin. This facilitates the recycling of guide rods without springs. When the first laser sensor detects an iron core, the spring detection mechanism detects the guide rod. If the spring detection mechanism detects more than one spring, the guide rod is moved into the recycling bin again via the clamping operation, making it easier to select guide rods containing multiple springs. If the spring detection mechanism detects only one spring, the guide rod is moved into the finished product bin via the conveying mechanism. Repeating all the above operations facilitates the rejection of guide rods containing multiple springs and those without springs, thereby reducing the labor intensity of operators.
[0009] Preferably, the detection mechanism includes a first hydraulic cylinder, which is mounted on the gantry frame. The piston rod of the first hydraulic cylinder is fixedly connected to a second sliding block. A first sliding groove is provided on one side of the second sliding block. A sliding rod is slidably arranged in the first sliding groove. A pressure plate is fixedly connected to one side of the sliding rod. The pressure plate can abut against the iron core. A third laser sensor is installed on the inner wall of the first sliding groove.
[0010] By adopting the above technical solution, when it is necessary to detect the number of springs, multiple first laser actuators detect springs on the guide rod, and then activate the first hydraulic cylinder. The piston rod of the first hydraulic cylinder drives the second sliding block to move vertically downward. The second sliding block drives the sliding rod to move, and the sliding rod drives the pressure plate to move. When the pressure plate abuts against the iron core, the pressure plate begins to be subjected to the elastic force of the spring. After the second sliding block continues to move vertically downward a certain distance, the weight of the sliding rod and the pressure plate itself is balanced with the elastic force of the spring. At this time, the sliding rod is detected by the third laser sensor. Since the degree of compression deformation of multiple springs is small when the weight of the sliding rod and the pressure plate is balanced with the elastic force of the spring, the position of the sliding rod with multiple springs abutting is higher than the position of the sliding rod with only one spring abutting when the sliding rod is in equilibrium. When the third laser sensor detects the sliding rod, it indicates that there are multiple springs on the guide rod. When the third laser sensor does not detect the sliding rod, it indicates that there is only one spring on the guide rod, thus facilitating the detection of the number of springs.
[0011] Preferably, the clamping mechanism includes a third sliding block, a second sliding groove is formed on one side wall of the first sliding block, the third sliding block is slidably disposed on the inner wall of the second sliding groove, a first clearance groove is formed on one side wall of the third sliding block, a motor is installed on the inner wall of the first clearance groove, the output end of the motor is drivenly connected to a bidirectional lead screw, the bidirectional lead screw is rotatably disposed on the inner wall of the first clearance groove, two clamping plates are provided on the bidirectional lead screw, the two clamping plates are respectively threaded with the two sections of the bidirectional lead screw, the clamping plates can abut against the side wall of the guide rod, the inner wall of the first clearance groove is provided with a guide member for guiding the clamping plates, and the first sliding block is provided with a driving member for driving the third sliding block to move in the vertical direction.
[0012] By adopting the above technical solution, when it is necessary to clamp the guide rod, the first sliding block is first driven by the drive mechanism to move to the top of the guide rod, and then the third sliding block is driven by the drive component to move vertically downward. The third sliding block drives the clamping plate to move vertically downward. When the clamping plate moves to the vicinity of the side wall of the guide rod, the motor is started. The output end of the motor drives the bidirectional screw to rotate. At the same time, the guide component guides the clamping plate, and the bidirectional screw drives the two clamping plates to move towards each other. When the clamping plate abuts against the guide rod, it is convenient to clamp the guide rod.
[0013] Preferably, the guide member includes a guide block, which is fixedly connected to one side of the clamping plate. The inner wall of the first clearance groove is provided with a guide groove, and the guide block is slidably disposed on the inner wall of the guide groove.
[0014] By adopting the above technical solution, when it is necessary to guide the clamping plate, the possibility of the clamping plate rotating during movement can be reduced by setting the guide block and guide groove, thereby making it easier to drive the clamping plate to move in a straight line.
[0015] Preferably, the driving component includes a second hydraulic cylinder, which is mounted on the inner wall of the second sliding groove, and the piston rod of the second hydraulic cylinder is fixedly connected to the third sliding block.
[0016] By adopting the above technical solution, when it is necessary to drive the clamping plate to move in the vertical direction, the second hydraulic rod is activated first, and the piston rod of the second hydraulic cylinder drives the third sliding block to move in the vertical direction, thereby facilitating the movement of the clamping plate in the vertical direction.
[0017] Preferably, the driving mechanism includes a guide rod, which is fixedly connected to the gantry frame. The first sliding block is slidably engaged with the guide rod. A third hydraulic cylinder is mounted on the gantry frame, and the piston rod of the third hydraulic cylinder is fixedly connected to the first sliding block.
[0018] By adopting the above technical solution, when it is necessary to drive the clamping plate to move linearly in the horizontal direction, the third hydraulic cylinder is activated first. The piston rod of the third hydraulic cylinder drives the first sliding block to move. At the same time, the guide rod can provide support and guidance for the first sliding block, thereby facilitating the driving of the first sliding block to move linearly in the horizontal direction, and thus facilitating the driving of the clamping plate to move linearly in the horizontal direction.
[0019] Preferably, the conveying mechanism includes a mounting block, which is fixedly connected to one side of the guide rail. A third sliding groove is provided on one side of the mounting block. A first cylinder is installed on the inner wall of the third sliding groove. A fourth sliding block is fixedly connected to the piston of the first cylinder. The fourth sliding block can abut against the side wall of the guide rod. A clamping member for clamping the guide rod is provided on the fourth sliding block.
[0020] By adopting the above technical solution, when it is necessary to transport the guide rod, one of the guide rods is first clamped by the clamping device, and then the first cylinder is activated. The piston of the first cylinder drives the fourth sliding block to move towards the finished product box. The fourth sliding block drives the guide rod to move. When the guide rod moves to the designated position, the clamping device releases the clamping action on the guide rod. Then the first cylinder drives the fourth sliding block to move to the vicinity of the guide rod adjacent to the first guide rod. When the fourth sliding block abuts against the side wall of the adjacent guide rod, the above operation is repeated, thereby facilitating the transport of the guide rod.
[0021] Preferably, the clamping member includes a second cylinder, a fourth sliding groove is provided on one side of the fourth sliding block, the second cylinder is installed on the inner wall of the fourth sliding groove, and the piston of the second cylinder is fixedly connected to an abutment plate, the abutment plate being able to abut against the guide rod.
[0022] By adopting the above technical solution, when it is necessary to clamp the guide rod, the fourth sliding block abuts against the side wall of the guide rod, and then the second cylinder is activated. The second cylinder drives the abutment plate to abut against the side wall of the guide rod, thereby facilitating the clamping of the guide rod.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. When the guide rod needs to be inspected, it is first conveyed to the designated position by the conveying mechanism, and then the guide rod is inspected by the first laser sensor. If the first laser sensor does not detect the iron core, it is because the iron core has fallen into the guide rod, resulting in the first laser sensor not detecting the iron core. Therefore, there is no spring on the guide rod. Then, the clamping mechanism clamps the guide rod and drives it to separate from the guide rail. After the guide rod is separated from the guide rail, the driving mechanism drives the first sliding block to move above the recycling box. At this time, the second laser sensor inspects the guide rod held by the clamping mechanism. If the second laser sensor does not detect the guide rod, the above clamping action is repeated until the second laser sensor detects it. When a guide rod is present, releasing the clamping mechanism facilitates moving the guide rod into the recycling bin, thus enabling the recycling of guide rods without springs. When the first laser sensor detects the presence of an iron core, the spring detection mechanism then detects the guide rod. If the spring detection mechanism detects that the number of springs is greater than one, the guide rod is moved into the recycling bin again through the aforementioned clamping operation, making it easier to select guide rods containing multiple springs. If the spring detection mechanism detects that the number of springs is one, the guide rod is moved into the finished product bin through the conveying mechanism. Repeating all the above operations facilitates the rejection of guide rods containing multiple springs and those without springs, thereby reducing the labor intensity of operators.
[0025] 2. When the number of springs needs to be detected, multiple first laser actuators detect springs on the guide rod, and then the first hydraulic cylinder is activated. The piston rod of the first hydraulic cylinder drives the second sliding block to move vertically downward. The second sliding block drives the sliding rod to move, and the sliding rod drives the pressure plate to move. When the pressure plate abuts against the iron core, the pressure plate begins to be subjected to the spring force. After the second sliding block continues to move vertically downward a certain distance, the weight of the sliding rod and the pressure plate itself is balanced with the spring force. At this time, the sliding rod is detected by the third laser sensor. Since the compression deformation of multiple springs is small when the weight of the sliding rod and the pressure plate is balanced with the spring force, the position of the sliding rod with multiple springs abutting is higher than the position of the sliding rod with only one spring abutting when the sliding rod is in equilibrium. When the third laser sensor detects the sliding rod, it means that there are multiple springs on the guide rod. When the third laser sensor does not detect the sliding rod, it means that there is only one spring on the guide rod, thus facilitating the detection of the number of springs.
[0026] 3. When it is necessary to clamp the guide rod, the first sliding block is first driven by the drive mechanism to move directly above the guide rod. Then, the third sliding block is driven by the drive component to move vertically downward. The third sliding block drives the clamping plate to move vertically downward. When the clamping plate moves to the vicinity of the side wall of the guide rod, the motor is started. The motor output drives the bidirectional lead screw to rotate. At the same time, the guide component guides the clamping plate. The bidirectional lead screw drives the two clamping plates to move towards each other. When the clamping plate abuts against the guide rod, it is easy to clamp the guide rod. Attached Figure Description

Detailed Implementation
[0034] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.
[0035] This utility model discloses a device for detecting defective guide rods, such as... Figure 1 As shown, the system includes a square worktable 1. A guide rail 11 is fixedly connected to the top of the worktable 1. A conveying mechanism 2 for conveying guide rods is provided at the bottom of the guide rail 11. The sidewalls of the guide rods abut against the guide rail 11. Four first laser sensors 12 for detecting the presence or absence of an iron core are installed on the guide rail 11. A gantry frame 13 is fixedly connected to the top of the worktable 1. A first sliding block 14 is provided on the gantry frame 13. The first sliding block 14 is square. A clamping mechanism 3 for clamping the guide rods is provided on the side of the first sliding block 14 near the worktable 1. A driving mechanism 4 for driving the first sliding block 14 to move along the width direction of the worktable 1 is provided on the gantry frame 13.
[0036] like Figure 2 As shown, a recycling bin 15 is fixedly connected to the top of the workbench 1. The recycling bin 15 is square. A second laser sensor 16 for detecting whether the clamping mechanism 3 is clamped to the guide rod is fixedly connected to the workbench 1. A detection mechanism 5 for detecting the number of springs on the guide rod is provided at the bottom of the gantry frame 13. A finished product box 17 is fixedly connected to the top of the workbench 1. The finished product box 17 is square.
[0037] When the guide rod needs to be detected, it is first conveyed to the designated position by the conveying mechanism 2, and then detected by the first laser sensor 12. When the first laser sensor 12 does not detect the iron core, it is because the iron core has fallen into the guide rod, resulting in the first laser sensor 12 not detecting the iron core. Therefore, there is no spring on the guide rod. Then, the clamping mechanism 3 clamps the guide rod and drives it to separate from the guide rail 11. After the guide rod is separated from the guide rail 11, the driving mechanism 4 drives the first sliding block 14 to move above the recycling box 15. At this time, the second laser sensor 16 detects the guide rod clamped by the clamping mechanism 3. When the second laser sensor 16 does not detect the guide rod, the above clamping action is repeated until the second laser sensor 16 detects the guide rod. When a guide rod is detected, the clamping mechanism 3 is released, allowing the guide rod to be moved into the recycling bin 15. This facilitates the recycling of guide rods without springs. When the first laser sensor 12 detects an iron core, the spring detection mechanism 5 detects the guide rod. When the spring detection mechanism 5 detects that the number of springs is greater than one, the guide rod is moved into the recycling bin 15 again through the clamping operation. This facilitates the selection of guide rods containing multiple springs. When the spring detection mechanism 5 detects that the number of springs is one, the guide rod is moved into the finished product bin 17 through the conveying mechanism 2. All the above operations are repeated to facilitate the rejection of guide rods containing multiple springs and guide rods without springs, thereby reducing the labor intensity of operators.
[0038] like Figure 1 and Figure 3 As shown, the detection mechanism 5 includes a first hydraulic cylinder 51, which is arranged vertically and is bolted to the gantry frame 13. The piston rod of the first hydraulic cylinder 51 is fixedly connected to a second sliding block 52, which is square in shape. A first sliding groove 53 is provided on the side of the second sliding block 52 near the worktable 1. The cross-section of the first sliding groove 53 is circular and extends vertically. A sliding rod 54 is slidably arranged vertically inside the first sliding groove 53. The cross-section of the sliding rod 54 is circular and arranged vertically. A pressure plate 55 is fixedly connected on the side of the sliding rod 54 near the worktable 1. The cross-section of the pressure plate 55 is circular and arranged vertically. The bottom of the pressure plate 55 can abut against the iron core. A third laser sensor 56 is installed on the inner wall of the first sliding groove 53.
[0039] When the number of springs needs to be detected, multiple first laser actuators detect springs on the guide rod and then activate the first hydraulic cylinder 51. The piston rod of the first hydraulic cylinder 51 drives the second sliding block 52 to move vertically downwards. The second sliding block 52 drives the sliding rod 54 to move, and the sliding rod 54 drives the pressure plate 55 to move. When the pressure plate 55 comes into contact with the iron core, the pressure plate 55 begins to be subjected to the spring force. After the second sliding block 52 continues to move vertically downwards a certain distance, the weight of the sliding rod 54 and the pressure plate 55 itself balances the spring force. At this time, the third laser actuator... Sensor 56 detects the sliding rod 54. Since the multiple springs have a small degree of compression deformation when the weight of the sliding rod 54 and the pressure plate 55 are balanced with the elastic force of the spring, the position of the sliding rod 54 with multiple springs is higher than the position of the sliding rod 54 with only one spring when the sliding rod 54 is in equilibrium. When the third laser sensor 56 detects the sliding rod 54, it means that there are multiple springs on the guide rod. When the third laser sensor 56 does not detect the sliding rod 54, it means that there is only one spring on the guide rod, which makes it easy to detect the number of springs.
[0040] like Figure 1 , Figure 4 and Figure 5 As shown, the clamping mechanism 3 includes a third sliding block 31, which is square in shape. A second sliding groove 32 is formed on the side wall of the first sliding block 14 near the worktable 1. The second sliding groove 32 has a square cross-section and extends vertically. The third sliding block 31 is slidably disposed on the inner wall of the second sliding groove 32 in the vertical direction. A first clearance groove 33 is formed on the side wall of the third sliding block 31 near the worktable 1. The first clearance groove 33 has a square cross-section and extends vertically. A motor 34 is bolted to the inner wall of the first clearance groove 33. The output end of the motor 34 is connected to a bidirectional lead screw 3. 5. The bidirectional lead screw 35 is arranged along the length of the worktable 1. The end of the bidirectional lead screw 35 away from the motor 34 is rotatably mounted on the inner wall of the first relief groove 33 through a bearing. Two clamping plates 36 are slidably arranged on the bidirectional lead screw 35 along its axial direction. The two clamping plates 36 are respectively threaded with the two sections of the bidirectional lead screw. The bidirectional lead screw 35 passes through the clamping plates 36. The clamping plates 36 can abut against the side wall of the guide rod. The inner wall of the first relief groove 33 is provided with a guide member 6 for guiding the clamping plates 36. The first sliding block 14 is provided with a driving member 7 for driving the third sliding block 31 to move in the vertical direction.
[0041] When the guide rod needs to be clamped, the first sliding block 14 is first moved to the top of the guide rod by the drive mechanism 4, and then the third sliding block 31 is moved vertically downward by the drive component 7. The third sliding block 31 drives the clamping plate 36 to move vertically downward. When the clamping plate 36 moves to the vicinity of the side wall of the guide rod, the motor 34 is started. The output end of the motor 34 drives the bidirectional lead screw 35 to rotate. At the same time, the guide component 6 guides the clamping plate 36, and the bidirectional lead screw 35 drives the two clamping plates 36 to move towards each other. When the clamping plate 36 abuts against the guide rod, it is easy to clamp the guide rod.
[0042] like Figure 4 and Figure 5 As shown, the guide member 6 includes a guide block 61. The guide block 61 has an isosceles trapezoidal cross-section and is axially arranged along the bidirectional lead screw 35. The guide block 61 is fixedly connected to one side of the clamping plate 36. The inner wall of the first clearance groove 33 is provided with a guide groove 62. The guide groove 62 has an isosceles trapezoidal cross-section and extends axially along the bidirectional lead screw 35. The guide block 61 is slidably disposed on the inner wall of the guide groove 62 along the bidirectional lead screw 35. When it is necessary to guide the clamping plate 36, the arrangement of the guide block 61 and the guide groove 62 can reduce the possibility of the clamping plate 36 rotating during movement, thereby facilitating the driving of the clamping plate 36 to move in a straight line.
[0043] like Figure 4 and Figure 5 As shown, the driving component 7 includes a second hydraulic cylinder 71, which is arranged vertically and bolted to the inner wall of the second sliding groove 32. The piston rod of the second hydraulic cylinder 71 is fixedly connected to the top of the third sliding block 31. When it is necessary to drive the clamping plate 36 to move vertically, the second hydraulic cylinder 71 is activated first, and its piston rod drives the third sliding block 31 to move vertically, thus facilitating the vertical movement of the clamping plate 36.
[0044] like Figure 1 As shown, the drive mechanism 4 includes a guide rod 41 with a square cross-section and arranged along the width direction of the worktable 1. The guide rod 41 is fixedly connected to the gantry frame 13. The first sliding block 14 slides with the guide rod 41 along the width direction of the worktable 1. The guide rod 41 passes through the first sliding block 14. A third hydraulic cylinder 42 is bolted onto the gantry frame 13. The third hydraulic cylinder 42 is arranged along the width direction of the worktable 1. The piston rod of the third hydraulic cylinder 42 is fixedly connected to one side of the first sliding block 14.
[0045] When it is necessary to drive the clamping plate 36 to move linearly in the horizontal direction, the third hydraulic cylinder 42 is activated first. The piston rod of the third hydraulic cylinder 42 drives the first sliding block 14 to move. At the same time, the guide rod 41 provides support and guidance for the first sliding block 14, which facilitates driving the first sliding block 14 to move linearly in the horizontal direction, and thus facilitates driving the clamping plate 36 to move linearly in the horizontal direction.
[0046] like Figure 1 and Figure 6 As shown, the conveying mechanism 2 includes a mounting block 21, which is square in shape and is fixedly connected to the guide rail 11 on the side near the worktable 1. A third sliding groove 22 is provided on the top of the mounting block 21. The cross-section of the third sliding groove 22 is square and extends along the length of the worktable 1. A first cylinder 23 is installed on the inner wall of the third sliding groove 22 by bolts. The first cylinder 23 is arranged along the length of the worktable 1. A fourth sliding block 24 is fixedly connected to the piston of the first cylinder 23. The fourth sliding block 24 is square in shape and can abut against the side wall of the guide rod. A clamping member 8 for clamping the guide rod is provided on the fourth sliding block 24.
[0047] When the guide rod needs to be transported, one of the guide rods is first clamped by the clamping member 8. Then, the first cylinder 23 is activated. The piston of the first cylinder 23 drives the fourth sliding block 24 to move towards the finished product box 17. The fourth sliding block 24 drives the guide rod to move. When the guide rod moves to the designated position, the clamping member 8 releases the clamping action on the guide rod. Then, the first cylinder 23 drives the fourth sliding block 24 to move to the vicinity of the guide rod adjacent to the first guide rod. When the fourth sliding block 24 abuts against the side wall of the adjacent guide rod, the above operation is repeated, which facilitates the transport of the guide rod.
[0048] like Figure 1 and Figure 6 As shown, the clamping component 8 includes a second cylinder 81. A fourth sliding groove 82 is formed on the top of the fourth sliding block 24. The fourth sliding groove 82 has a square cross-section and extends along the width of the worktable 1. The second cylinder 81 is bolted to the inner wall of the fourth sliding groove 82. The second cylinder 81 is positioned along the width of the worktable 1. A stop plate 83 is fixedly connected to the piston of the second cylinder 81. The stop plate 83 is square, and its sidewall can abut against the guide rod. When the guide rod needs to be clamped, the fourth sliding block 24 abuts against the sidewall of the guide rod. Then, the second cylinder 81 is activated, driving the stop plate 83 to abut against the sidewall of the guide rod, thus facilitating clamping of the guide rod.
[0049] The implementation principle of the guide rod defect detection device in this application embodiment is as follows:
[0050] When the guide rod needs to be detected, it is first conveyed to the designated position by the conveying mechanism 2, and then detected by the first laser sensor 12. When the first laser sensor 12 does not detect the iron core, it is because the iron core has fallen into the guide rod, resulting in the first laser sensor 12 not detecting the iron core. Therefore, there is no spring on the guide rod. Then, the clamping mechanism 3 clamps the guide rod and drives it to separate from the guide rail 11. After the guide rod is separated from the guide rail 11, the driving mechanism 4 drives the first sliding block 14 to move above the recycling box 15. At this time, the second laser sensor 16 detects the guide rod clamped by the clamping mechanism 3. When the second laser sensor 16 does not detect the guide rod, the above clamping action is repeated until the second laser sensor 16 detects the guide rod. When a guide rod is detected, the clamping mechanism 3 is released, allowing the guide rod to be moved into the recycling bin 15. This facilitates the recycling of guide rods without springs. When the first laser sensor 12 detects an iron core, the spring detection mechanism 5 detects the guide rod. When the spring detection mechanism 5 detects that the number of springs is greater than one, the guide rod is moved into the recycling bin 15 through the clamping operation described above. This facilitates the selection of guide rods containing multiple springs. When the spring detection mechanism 5 detects that the number of springs is one, the guide rod is moved into the finished product bin 17 through the conveying mechanism 2. Repeating all the above operations facilitates the rejection of guide rods containing multiple springs and guide rods without springs, thereby reducing the labor intensity of operators.
[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
