[0063] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the figures only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0064] Example 1:

[0065] like Figures 1-23 As shown, a four-way lock-picking machine includes a lock body transport device 1, a lock beam hole verification device 2, a lock beam mounting device 3, a ball bearing mounting device 4, a lock cylinder placement device 5, a sealing cover device 6, and a lock cylinder assembly device 7. The lock body transport device 1 is used to transport the lock body to a set position. In this example, the lock body transport device 1 is connected to the lock beam hole verification device 2. The lock body transport device 1 is used to transport the lock body to the lock beam hole verification device. In this example, the lock body refers to the shell part of the padlock, that is, the outer shell body used to install the lock cylinder and lock beam. The lock body has holes for installing the lock cylinder and holes for installing the lock beam. Usually, the holes for installing the lock cylinder and the holes for installing the lock beam are located on both sides of the lock body. The lock beam hole verification device 2 is used to check... The lock body is positioned according to the lock beam hole, and the lock body is adjusted in position and angle according to the deviation of the lock beam hole to facilitate the installation of the lock beam; the lock beam hole calibration device 2 is also connected to the lock beam installation device 3, and the lock beam is installed after the lock beam hole calibration is completed; the lock beam installation device 3 is connected to the ball bearing installation device 4, which is used to place two balls on the side wall inside the lock cylinder hole; the ball bearing installation device 4 is connected to the lock cylinder placement device 5, which is used to place the lock cylinder assembled by the lock cylinder assembly device 7, and put the lock cylinder into the lock cylinder hole of the lock body; the lock cylinder placement device 5 is also connected to the pressure sealing device 6, which is used to press the sealing cover into the lock cylinder hole where the lock cylinder is placed, and to restrict the lock cylinder inside the lock cylinder hole.

[0066] It also includes a support frame 8; the support frame 8 includes a base plate 81, a top plate 82, and several support rods 83; wherein the support rods 83 are disposed between the base plate 81 and the top plate 82; in this example, the lock body transport device 1, the lock beam hole verification device 2, the lock beam installation device 3, the ball bearing installation device 4, the lock cylinder placement device 5, and the pressure sealing cover device 6 are all disposed in the area between the top plate 82 and the base plate 81; part of the lock cylinder assembly device 7 is disposed on the top plate 82, and part is disposed between the base plate 81 and the top plate 82, and the lock cylinder assembly device 7 located between the base plate 81 and the top plate 82 corresponds to the lock cylinder placement device 5. In this example, four support rods 83 are disposed between the top plate 82 and the base plate 81, and the four support rods 83 are respectively disposed at the four corners of the square top plate 82.

[0067] The lock body transport device 1 includes a first transport structure 11 and a gripping structure 12. The first transport structure 11 includes a conveyor belt for transporting the lock body, and a gripping structure 12 for gripping and transporting the lock body is provided at the end of the conveyor belt. The gripping structure 12 includes a gripping member 121 for fixing the lock body, a first gripping moving member 122 for horizontal movement, and a second gripping moving member 123 for controlling the vertical movement of the gripping member 121. The gripping member 121 is disposed at the moving end of the second gripping moving member 123. The second gripping moving member 123 is fixedly disposed at the moving end of the first gripping moving member 122. In this example, both the first gripping moving member 122 and the second gripping moving member 123 include cylinders, which drive their movement. The gripping member 121 is a finger cylinder, used to grip the lock body on the conveyor belt, and transfer the lock body to the lock beam hole verification device 2 through the first gripping moving member 122 and the second gripping moving member 123.

[0068] The lock beam hole verification device 2 includes a clamping assembly 21 for clamping and fixing the lock body; it also includes an alignment assembly 22 for aligning the two lock beam holes on the lock body; the alignment assembly 22 is arranged adjacent to the clamping assembly 21; the alignment assembly 22 includes a first moving device 221 and an alignment rod 222 that matches the lock beam hole; there are two alignment rods 222, which are parallel to each other and fixedly arranged on the slider of the first moving device 221 at a set interval, and the alignment rods 222 face the clamping assembly 21; in this example, the first moving device 221 includes a first moving cylinder, and the movable end of the first moving cylinder is provided with a first moving slider on which the alignment rods 222 are fixed; the movement direction of the first moving device 221 is towards the clamping assembly 21.

[0069] The clamping assembly 21 includes a second moving device 212 and a third moving device 213; wherein the third moving device 213 is arranged vertically, and a positioning block 214 is provided on the third moving device 213; the positioning block 214 is located above the third moving device 213; the movement direction of the second moving device 212 is towards the positioning block 214. Through the cooperation of the second moving device 212 and the third moving device 213, the clamping and releasing of the lock body are achieved. The second moving device 212 includes a second moving cylinder; the third moving device 213 includes a third moving cylinder.

[0070] The lock beam hole calibration device 2 further includes a correction component 23; the correction component 23 is disposed at the movable end of the second motion device 212; the correction component 23 includes a fixed base 231 and a roller 232, the roller 232 is rotatably disposed on the fixed base 231, the roller 232 is located in the horizontal direction, and the axis of the roller 232 is perpendicular to the motion direction of the second motion device 212. By setting the correction component 23, during the process of the alignment rod 222 contacting and extending into the lock beam hole, the lock body is more easily adjusted in posture because one end is in contact with the roller 232 in the correction component 23, making it easier for the alignment rod 222 to extend into the lock beam hole.

[0071] A guide 24 is also provided between the fixed base 231 and the second motion device 212; in this example, the guide 24 is a guide rod, and there are two guide rods in total; the two guide rods are located on the left and right sides of the cylinder in the second motion device 212 respectively; one end of the two guide rods is fixedly connected to the fixed base 231, and the two guide rods are also slidably connected to the cylinder to ensure that the lock beam fixing plate 422 is pushed towards the lock body in a translational posture.

[0072] The alignment rod 222 has a pointed end near the clamping assembly 21; this facilitates the alignment rod 222 extending into the corresponding lock beam hole and adjusting the two lock beam holes to correspond to the two alignment rods 222. This allows for inspection of the two lock beam holes on the lock body and facilitates the subsequent installation of the lock beam. An elastic element, in this example a spring, is also sleeved around the outer periphery of the alignment rod 222. This elastic element ensures that when the alignment rod 222 extends into the lock beam hole of the lock body, it contacts the lock body and applies a force towards the clamping assembly 21, making the lock body more stable on the clamping assembly 21.

[0073] The lock beam hole verification device 2 further includes a fourth motion device 25; the fourth motion device 25 includes a horizontally arranged fourth motion track, a power component, and a fourth motion slider, the direction of the fourth motion track being perpendicular to the motion direction of the second motion device 212; the second motion device 212 and the third motion device 213 are fixedly mounted on the fourth motion slider; the power component is a fourth motion cylinder. By setting the fourth motion device 25, it is convenient to clamp the lock body after the lock beam hole is aligned and send it to the next process, that is, to send the lock body to the area of ​​the lock beam installation device 3 for lock beam installation.

[0074] During the operation of the lock beam hole verification device 2, the alignment component 22, including two alignment rods 222, works in conjunction with the clamping component 21 to verify and align the positions of the two lock beam holes on the lock body of the padlock to be installed, facilitating the subsequent installation of the lock beam. The clamping component 21, including a horizontally moving second motion device 212 and a vertically moving third motion device 213, allows one end of the lock body to abut against the third motion device 213, while the other end of the lock body is pressed by the second motion device 212, achieving clamping and fixation. The correction component 23, including a roller 232, is set on the second motion device 212 to facilitate the adjustment of the lock body's posture when aligned with the alignment rods 222. The front end of the alignment rod 222 is a pointed tip, facilitating its insertion into the lock beam hole. An elastic element is set on the outer periphery of the alignment rod 222, so that when the alignment rod 222 is inserted into the lock body, the elastic element can also apply a force towards the second motion device 212 to the lock body, ensuring that it is clamped by the clamping component 21.

[0075] The lock beam installation device 3 includes a pushing structure 31 for pushing the lock beam into the lock body; the pushing structure 31 includes a stacking component 311 for stacking the lock beam, a lock beam pushing component 312 for pushing the lock beam, and a lock beam support plate 313; the stacking component 311 includes a U-shaped lock beam locking block; the lock beam locking block is located inside the U-shaped lock beam, and the lock beam slides up and down along the lock beam locking block; the lock beam pushing component 312 is fixedly installed on the lock beam support plate 313; the lock beam locking block is fixedly installed at a set distance above the lock beam support plate 313, and there is a set gap between the lock beam locking block and the lock beam support plate 313, so that the lock beam on the lock beam locking block can fall onto the lock beam support plate 313, and the lock beam is pushed into the lock beam hole of the lock body by the lock beam pushing component 312, which is transported by the fourth motion device 25 in the lock beam hole inspection device.

[0076] The ball bearing installation device 4 includes a second transport structure 41 for transferring the lock body and a lock beam fixing structure 42 for fixing the lock beam to be installed with the ball bearings. The second transport structure 41 includes a lock body clamping and flipping component 411 and a lock body actuating component 412. The movement trajectory of the lock body clamping and flipping component 411 is opposite to that of the fourth motion device 25 in the lock beam hole inspection device, so that the fourth motion device 25 can move the lock body to a position close to the lock body clamping and flipping component 411. The lock body clamping and flipping component 411 also corresponds to the lock beam fixing structure 42. The lock body actuating component 412 is located near the lock body clamping and flipping component 411. After the lock body clamping and flipping component 411 clamps the lock body and flips it to the vertical direction, the lock body actuating component 412 pushes the lock body onto the lock beam fixing structure 42. The lock beam fixing structure 42 can be achieved by vacuum adsorption or physical clamping. The ball bearing mounting device 4 also includes a first magnetic structure 43 and a first vibration structure 44; the first magnetic structure 43 is fixedly mounted on the lock beam fixing structure 42; the first magnetic structure 43 contacts the lock beam of the lock to be installed, providing magnetism to the magnetically conductive lock beam, so that the lock beam can attract the ball bearing; the first vibration structure 44 is connected to the lock beam fixing structure 42, driving the lock beam fixing structure 42 to move.

[0077] The lock body clamping and flipping component 411 includes a flipping push cylinder 4111 and a first lock beam clamping plate 4112. The first lock beam clamping plate 4112 is provided with a lock body groove corresponding to the lock body, so that the lock body can be pushed into the lock body groove from the side of the first lock beam clamping plate 4112. The end of the first lock beam clamping plate 4112 away from the lock body groove is hinged to the fixed end of the flipping push cylinder 4111. The first lock beam clamping plate 4112 is also hinged to the movable end of the flipping push cylinder 4111 or connected by a snap tooth. In this example, it is a snap tooth connection, so that when the flipping push cylinder 4111 is activated, as the cylinder rod extends, it pushes the first lock beam clamping plate 4112 to rotate.

[0078] The lock body actuating component 412 includes a lock body lever and an actuating cylinder, wherein the lock body lever is connected to the movable end of the actuating cylinder; when the actuating cylinder is activated, it pushes the lock body from the first lock beam clamping plate 4112 in the lock body clamping and flipping component 411 into the lock beam fixing structure 42.

[0079] The locking beam fixing structure 42 includes a second locking beam clamping plate 421, a locking beam fixing plate 422, and a locking beam clamping cylinder 423; a guide member 24 is provided between the second locking beam clamping plate 421 and the locking beam fixing plate 422; the locking beam clamping cylinder 423 is fixedly mounted on the locking beam fixing plate 422; the locking beam clamping cylinder 423 is located between the locking beam fixing plate 422 and the second locking beam clamping plate 421; a first magnetic structure 43 is also provided at one end of the locking beam clamping cylinder 423 away from the locking beam fixing plate 422.

In this example, the first and second clamping plates are integrally formed, with their lower ends connected to each other. A predetermined gap is maintained at the upper part of the first and second clamping plates for the insertion of the lock beam portion. It should be noted that in some other embodiments, the first and second clamping plates can be separated from each other, wherein a spacer block is provided on the guide member 24 to separate the first and second clamping plates. The spacer block is located between the first and second clamping plates to control the minimum gap between them. The guide member 24 is a guide rail, and there is at least one guide rod. In this example, two guide rails are provided, located on the left and right sides of the lock beam clamping cylinder 423, respectively. Both guide rails are horizontally arranged and are used to control the distance between the lock beam fixing plate 422 and the second lock beam clamping plate 421, thereby controlling the distance between the lock beam clamping cylinder 423 on the lock beam fixing plate 422 and the second lock beam clamping plate 421, to accommodate locks of different sizes.

[0080] The first magnetic structure 43 is disposed on the second clamping plate in the second locking beam clamping plate 421.

It should be noted that in some other embodiments, the lock body moving structure 45 can also employ other existing transverse movement mechanisms, such as cylinders or hydraulic cylinders. Since the first vibration structure 44 will generate some shaking during operation, which may cause spatial interference to surrounding devices, the lock body moving structure 45 allows it to be moved to a more open central area for vibration, reducing interference to adjacent devices and facilitating docking with adjacent devices.

[0083] The ball bearing mounting device 4 also includes a ball bearing pusher 46, which corresponds to the movement path of the lock body moving structure 45. The ball bearing pusher 46 includes a ball bearing pusher 461, a ball bearing cylinder 462, a ball bearing tube 463, and a ball bearing plate 464. The ball bearing plate is located above the lock beam fixing structure 42. A ball bearing tube 463 is fixedly installed at a set interval above the ball bearing plate 464. The distance between the ball bearing plate 464 and the ball bearing tube 463 is greater than or equal to the diameter of a ball bearing. The diameter of the ball bearing tube 463 corresponds to the ball bearing. The ball bearing pusher 461 is located between the ball bearing plate 464 and the ball bearing tube 463. The ball bearing pusher 461 is also connected to the movable end of the ball bearing cylinder 462. The ball bearing pusher 461 is provided with a through hole corresponding to the ball bearing. The ball falls from the ball tube 463 into the through hole on the ball push rod 461. When the ball push rod 461 is pushed, it pushes out the distance of the ball plate 464. At this time, the ball in the through hole of the ball push rod 461 falls from the ball plate 464 and falls into the lock cylinder hole of the corresponding lock body below via the lock body moving structure 45.

[0084] During the operation of the ball bearing installation device 4, by setting the first magnetic structure 43 to contact the lock beam and cooperating with the first vibration structure 44, the ball bearing falling into the lock cylinder hole can be smoothly attracted by the magnetic lock beam and remain in the corresponding hole, achieving efficient ball bearing installation. By setting the lock beam clamping cylinder 423 and setting the first magnetic structure 43 on the lock beam clamping cylinder 423, in conjunction with the second lock beam clamping plate 421, the lock to be installed is clamped, preventing it from detaching from the device when the first vibration structure 44 is activated, ensuring a stable installation process. By setting the guide rod, the distance between the lock beam fixing plate 422 and the second lock beam clamping plate 421 can be adjusted to accommodate the installation of locks of different sizes. By setting the lock body moving structure 45, this device can better cooperate with adjacent external devices, reducing interference to adjacent devices.

It should be noted that in some other embodiments, an electromagnet, a suction cup, or other structure capable of fixing the lock body can also be used as the lock body clamp 511.

[0086] The first moving structure 512 further includes a first moving guide rail and a first moving base; the first moving slider is slidably disposed on the first moving guide rail; the first moving guide rail is fixedly disposed on the first moving base; the first moving base is fixedly connected to the second moving slider of the second moving structure 513; in this example, the first moving structure 512 uses an existing linear guide rail, which facilitates control of the sliding accuracy of the first moving slider on the first moving guide rail. The first moving structure 512 also includes a positioning device for fixing the first moving slider on the first moving guide rail; the positioning device includes a positioning clamp and a positioning rod, the positioning clamp and the positioning rod being correspondingly disposed; the positioning rod is fixedly connected to the second moving slider, and in this example, the positioning rod is fixedly connected to the first moving base on the second moving slider; the positioning clamp is fixedly connected to the first moving slider; the axial direction of the positioning rod is consistent with the length direction of the first moving guide rail. The positioning clamp uses a finger cylinder; by clamping the positioning rod with the positioning clamp, the first moving slider on the first moving guide rail is positioned.

[0087] The second moving structure 513 further includes a second moving guide rail, a second moving base, and a second moving cylinder; the second moving slider is slidably disposed on the second moving guide rail; the second moving slider is also connected to the second moving cylinder and driven by the second moving cylinder; the second moving guide rail is fixedly disposed on the second moving base.

[0088] The telescopic component includes a telescopic cylinder, which is fixedly mounted above the lock body clamp 511.

[0089] The edge of the lock hole rod near the lock body clamp 511 is provided with a rounded corner or chamfer, so that the end of the lock hole rod near the lock body clamp 511 forms a gradually tapering end, which makes it convenient for the lock hole rod to be inserted into the lock cylinder hole on the lock body.

[0090] The lock cylinder placement device 5 also includes a third moving structure 53 for transferring the second moving structure 513 in the lock cylinder hole correction structure 51. The second moving structure 513 can be docked with the previous assembly device on the padlock assembly line to facilitate the transfer of the lock body to the lock body clamp 511.

[0091] The third movable slide rail is fixedly mounted on the base plate 81 of the support frame 8; the telescopic component is fixedly mounted on the top plate 82; and a space for the lock hole rod to pass through is also provided on the top plate 82.

[0092] To ensure that the lock hole rod does not deviate when moving up and down, a linear bearing is provided below the telescopic component, passing through the lock hole rod. In this example, the linear bearing is fixed on the support rod 83 between the bottom plate 81 and the top plate 82, and the linear bearing is located between the telescopic component and the lock body clamp 511.

[0093] During implementation, by setting a first moving structure 512 and a second moving structure 513 for adjusting the position of the lock body clamp 511, the lock body clamp 511 can be adjusted in the horizontal plane, facilitating the position correction of the lock cylinder hole on the lock body and ensuring that the lock cylinder hole is aligned with the set position of the lock hole rod, making it convenient to insert the lock cylinder into the lock cylinder hole in subsequent processes. By setting a positioning device between the first moving structure 512 and the second moving structure 513, the position of the first moving slider relative to the second moving slider is fixed, reducing the shaking displacement deviation generated by the first moving structure 512 during the lock body's transport.

By setting the lock hole rod to pass through a fixed linear bearing, the lock hole rod is ensured to slide up and down along a straight line, reducing shaking and facilitating alignment with the lock cylinder hole.

[0094] The lock cylinder assembly device 7 includes a lock plate orientation and transmission structure 71 and a lock cylinder assembly structure 72; wherein the lock plate orientation and transmission structure 71 is disposed above the lock cylinder assembly structure 72; in this example, the lock plate orientation and transmission structure 71 is disposed above the top plate 82 of the support frame 8; the lock cylinder assembly structure 72 is disposed between the top plate 82 and the bottom plate 81 of the support frame 8. The lock plate orientation and transmission structure 71 is used to attach the lock plate to the set rod according to the set direction and front and back sides; the lock cylinder assembly structure 72 is used to push the oriented lock plate into the set lock cylinder sleeve to complete the assembly of the lock cylinder.

[0095] The locking plate orientation and transmission structure 71 includes a vibration transmission structure 711 for transporting the locking plate; it should be noted that in this example, the locking plate is generally circular, with rounded edges on the front side and a flat back side. The edges of the locking plate also have arc-shaped notches and semi-circular protrusions, and the central area of ​​the locking plate has a through hole of a predetermined size. The locking plate orientation and transmission structure 71 also includes a locking plate orientation structure 712 connected to the vibration transmission structure 711 and a delivery structure 713 for feeding the locking plate to subsequent processes; the locking plate orientation structure 712 includes a through groove 712 for the passage of the locking plate. 1. A first moving member 7122, a second moving member 7123, a third moving member 7124, a first rotating member 7125, a proximity sensor 7126, and a first straight rod 7127 and a second straight rod 7128 for fitting into the locking plate. The cross-sectional shapes of the first straight rod 7127 and the second straight rod 7128 correspond to the shapes of the through holes on the locking plate. The inlet of the through groove 7121 is connected to the outlet of the vibration transmission structure 711. The outlet of the through groove 7121 is connected to the delivery structure 713. The first moving member 7122 is fixedly disposed above the through groove 7121, and the direction of movement of the first moving member 7122 is... The movement direction of the locking piece in the passageway 7121 is consistent with that of the first moving member 7122; the second moving member 7123 is fixedly disposed at the movable end of the first moving member 7122, and the second moving member 7123 moves with the movement of the first moving member 7122; the second moving member 7123 is located in the vertical direction; the movable end of the second moving member 7123 is fixedly disposed with a first rotating member 7125 and a second straight rod 7128, the first rotating member 7125 is located on the side near the entrance of the passageway 7121, and the second straight rod 7128 is located on the side near the exit of the passageway 7121; the first rotating member 7125 includes a motor for rotation, the motor's... A first straight rod 7127 is mounted on the rotating shaft. A first moving member 7122 controls the reciprocating movement of the first straight rod 7127 and the second straight rod 7128 along the direction of the through-slot 7121. A second moving member 7123 controls the first straight rod 7127 and the second straight rod 7128 to move closer to and further away from the through-slot 7121. A proximity sensor 7126 for detecting protrusions on the lock plate is also mounted within the through-slot 7121. A third moving member 7124 for pushing the lock plate away from the through-slot 7121 is also mounted within the through-slot 7121, and the third moving member 7124 is correspondingly mounted to the proximity sensor 7126. It should be noted that in this example, the first moving member 7122, the second moving member 7123, and the third moving member 7124 are all cylinder components.

[0096] The vibration conveying structure 711 includes a vibrating feeding tray for sequentially conveying locking plates; it should be noted that the vibrating feeding tray uses an existing device and is not shown in the attached drawings. The vibration conveying structure 711 also includes a vibration screening channel; the vibration screening channel is located between the vibrating feeding tray and the entrance of the passageway 7121; the vibration screening channel includes a vibration device 7111, a conveying channel 7112 for vibrating and conveying the locking plates, a first guardrail 7113 for screening the front and back sides of the locking plates, and a second guardrail 7114 for ensuring the passage of the locking plates; wherein the conveying channel 7112 is connected to the vibration device 7111 for controlling its vibration; the first guardrail 7113 and the second guardrail 7114 are protruding... The first rail 7113 and the second rail 7114 are connected on the same side of the conveying channel 7112. The first rail 7113 is located at the end of the second rail 7114 near the vibrating feed plate. The side of the conveying channel 7112 near the first rail 7113 and the second rail 7114 is tilted downward at a set angle to ensure that the locking plate moves forward while adhering to the first rail 7113 or the second rail 7114. The height of the protrusion of the first rail 7113 is lower than that of the second rail 7114, and the height of the protrusion of the first rail 7113 is a set value. Since the transport channel 7112 is inclined, the locking piece vibrating forward in the transport channel 7112 will abut against the first rail edge 7113 or the second rail edge 7114. The front edge of the locking piece is rounded. With the first rail edge 7113 at a set height, it will pass over the first rail edge 7113 and leave the transport channel 7112 as it vibrates. In addition, the locking piece located at the top of the stacked locking pieces will also leave the transport channel 7112 from the first rail edge 7113.

[0097] The transport channel 7112 is also provided with a limiting block for the passage of the locking piece at one end near the through slot 7121. A gap for the locking piece to pass through is provided between the limiting block and the transport channel 7112. The limiting block is located on the side of the transport channel 7112 away from the first side rail 7113 and the second side rail 7114. In this example, the limiting block is a cylinder, and the axis of the cylinder is aligned with the transport direction of the transport channel 7112.

[0098] The through-slot 7121 has a push-out port on its side, located between the inlet and outlet of the through-slot 7121, and corresponding to the third moving member 7124; the third moving member 7124 is located on the side of the through-slot 7121. The movement of the third moving member 7124 pushes the locking piece away from the through-slot 7121 through the push-out port on its side. The through-slot 7121 also has an upper pressing block, with a gap between the upper pressing block and the through-slot 7121 to restrict the movement of the locking piece, prevent overlapping of the locking pieces, and reduce the shaking and rotation of the locking piece when the first straight rod 7127 separates from the locking piece. In this example, the upper pressing block and the through-slot 7121 are integrally formed, and a perforated strip structure is provided on the side of the upper pressing block near the through-slot 7121 as a gap.

[0099] The through slot 7121 includes a first through slot for the lock plate to pass through and a second through slot for the first straight rod 7127 and the second straight rod 7128 to extend into. The second through slot is located at the bottom of the first through slot, and the width of the second through slot is smaller than the width of the first through slot. By providing the second through slot, the first straight rod 7127 and the second straight rod 7128 can continue to extend to the bottom of the second through slot when they are inserted into the through hole on the lock plate. This ensures that the first straight rod 7127 and the second straight rod 7128 can effectively pass through the lock plate, and also limits the angle at which the first straight rod 7127 and the second straight rod 7128 pass through the lock plate to a certain extent. In this example, the width of the second through slot corresponds to the width of the first straight rod 7127 and the second straight rod 7128, so that the first straight rod 7127 and the second straight rod 7128 can only extend into the second through slot when they are aligned with the second through slot in the width direction. This limits the orientation of the lock plate controlled by the rotation of the first straight rod 7127 to only two directions.

[0100] The first through slot of the passageway 7121 is L-shaped, allowing the locking piece to stop at the corner of the L-shaped first through slot, awaiting the action of the first straight rod 7127. This prevents the locking piece from being squeezed into the passageway 7121 due to excessively rapid vibration transmission, which would affect the action of the proximity sensor 7126, the first straight rod 7127, the second straight rod 7128, etc., and also facilitates the insertion of the first straight rod 7127 into the through hole on the locking piece. In this example, the part of the first through slot that connects to the transport channel 7112 is set as an inclined surface corresponding to the transport channel 7112, facilitating the docking between the transport channel 7112 and the first through slot, allowing the locking piece to smoothly transition from the transport channel 7112 to the passageway 7121. It should be noted that the inclined surface in the first through slot is inclined towards the side away from the outlet of the passageway 7121, further facilitating the locking piece to be locked at the corner of the first through slot.

[0101] The locking plate orientation structure 712 also includes a second rotating member 7129, which is located between the movable end of the second moving member 7123 and the second straight rod 7128. The second straight rod 7128 is disposed on the rotating shaft of the second rotating member 7129, so that the second straight rod 7128 can better extend into the through hole on the locking plate.

[0102] The ends of the first straight rod 7127 and the second straight rod 7128 near the through slot 7121 are also rounded to facilitate their insertion into the through hole on the lock plate.

[0103] The delivery structure 713 includes a fixedly installed third straight rod 7131, a first limiting structure 7132, and a second limiting structure 7133. The third straight rod 7131 is vertically installed at the exit of the through slot 7121. Both the first limiting structure 7132 and the second limiting structure 7133 are finger-moving components. The first limiting structure 7132 and the second limiting structure 7133 are fixedly installed vertically at predetermined heights on the third straight rod 7131. By setting the first limiting structure 7132 and the second limiting structure 7133, the lock piece fitted on the third straight rod 7131 can pass through the first limiting structure 7132 and the second limiting structure 7133 in sequence, achieving a staged descent, which facilitates the insertion of the lock pieces one by one into the lock cylinder sleeve in the lock cylinder assembly structure 72.

[0104] The proximity sensor 7126 is a conventional photoelectric sensor or infrared sensor that can detect the approach of an object. To avoid interference, a through sensor detection hole is provided at a set position in the passageway 7121. When the locking plate passes through and stops at the set position, the protrusion on the upright locking plate faces the top of the sensor detection hole. The proximity sensor 7126 inside the sensor detection hole senses that an object has passed through and stopped above the sensor detection hole, thus realizing the orientation detection of the locking plate.

[0105] During the operation of the locking plate orientation transmission structure 71, a proximity sensor 7126, in conjunction with a third moving component 7124, detects the orientation of the locking plates, ensuring that the locking plates transported to the second straight rod 7128 have a consistent orientation. A vibration screening channel, including an inclined transport channel 7112, along with a first railing 7113 at a set height, screens stacked and reversed locking plates, causing them to leave the transport channel 7112. A limiting block is placed at the end of the transport channel 7112 to restrict the movement space of the locking plates and control their movement. It moves along a set trajectory; by setting an upper pressure block on the through slot 7121, with a gap between the upper pressure block and the through slot 7121, one purpose is to restrict the passage of the locking piece and prevent the locking pieces from overlapping, and also to reduce the shaking and rotation of the locking piece when the first straight rod 7127 separates from the locking piece; by setting the first through slot and the second through slot to overlap, on the one hand, it ensures that the first straight rod 7127 and the second straight rod 7128 can effectively pass through the locking piece, and on the other hand, it can also restrict the passage of the first straight rod 7127 and the second straight rod 7128 through the locking piece to a certain extent. The angle restricts the orientation of the locking piece controlled by the rotation of the first straight rod 7127 to only two directions; by setting the first through groove to be L-shaped, the locking piece can stop at the corner of the L-shaped first through groove; by setting the part of the first through groove that connects to the transport channel 7112 to be an inclined surface corresponding to the transport channel 7112, it is convenient for the transport channel 7112 and the first through groove to dock, so that the locking piece can smoothly transition from the transport channel 7112 to the through groove 7121. In addition, the inclined surface is inclined towards the side away from the outlet of the through groove 7121. This design facilitates the locking plate to be engaged at the corner of the first through groove; by setting the ends of the first straight rod 7127 and the second straight rod 7128 near the through groove 7121 to be rounded, it is convenient for them to be inserted into the through hole on the locking plate; by setting the delivery structure 713 to include the first limiting structure 7132 and the second limiting structure 7133, the locking plate sleeved on the third straight rod 7131 can pass through the first limiting structure 7132 and the second limiting structure 7133 in sequence, realizing a phased descent, which facilitates the control of the locking plates to be installed into the lock cylinder one by one in subsequent processes.

[0106] The lock cylinder assembly structure 72 is correspondingly arranged with the lock cylinder clamping and transport structure 52, facilitating the pushing of lock pieces one by one into the lock cylinder sleeve clamped by the lock cylinder clamping and transport structure 52, thus completing the assembly of the lock cylinder. The lock cylinder clamping and transport structure 52 also includes a vertical lock cylinder transport component 523, and a horizontal lock cylinder transport component 521 is fixedly arranged in the movable part of the vertical lock cylinder transport component 523. In this example, the vertical lock cylinder transport component 523 includes a slider, a slide rail, and a cylinder, which controls the vertical movement of the horizontal lock cylinder transport component 521, thereby facilitating the up-and-down movement of the lock cylinder sleeve clamped by the lock cylinder clamping component 522, and making it easier to insert multiple lock pieces into the lock cylinder sleeve.

[0107] The lock cylinder assembly structure 72 includes a lock plate push rod 721 connected to a cylinder and a lock plate positioning member 722. The lock plate positioning member 722 has lock plate holes corresponding to the delivery structure 713 in the lock plate orientation transmission structure 71. The side of the lock plate holes also has push holes for the lock plate push rod 721 to pass through. The lock plate push rod 721 is movably disposed within the push holes, used to push the lock plate that falls into the lock plate hole into the lock cylinder sleeve clamped by the lock cylinder clamping member 522 in one go, finally assembling into a complete lock cylinder, used to cooperate with the lock cylinder placement device 5 to complete the installation of the lock cylinder into the lock body. In this example, multiple lock plate positioning members 722 are provided, and different lock plate positioning members 722 have lock plate holes of different sizes to realize the installation of lock plates of different sizes into the lock cylinder sleeve.

[0108] The sealing cap device 6 is used to press the conveyed cap into the lock body through a cylinder; wherein the cap is conveyed by vibration and pushed into the set hole by the cylinder, and then pressed into the lock body below by the cylinder above the hole, thus completing the assembly of the padlock.

[0109] A four-way lock-picking method, based on the aforementioned four-way lock-picking machine, comprising the following steps:

[0110] Step 1: The lock body is transferred from the lock body transport device 1 to the lock beam hole verification device 2;

[0111] Step 2: The lock beam hole verification device 2 verifies the position of the lock beam hole on the lock body and adjusts the posture of the clamped lock body according to the position of the lock beam hole;

[0112] Step 3: The lock beam is pushed into the lock body after the lock beam hole has been checked by the lock beam installation device 3;

[0113] Step 4: The ball bearing installation device 4 lowers the ball bearing from the lock cylinder hole on the lock body into the lock body;

[0114] Step 5: The first vibration structure 44 in the ball bearing mounting device 4 vibrates to embed the ball bearing into the set position on the inner wall of the lock cylinder hole.

[0115] Step 6: The lock cylinder assembly device 7, in conjunction with the lock cylinder placement device 5, completes the assembly of the lock cylinder, and the assembled lock cylinder is placed into the lock cylinder hole of the lock body through the lock cylinder placement device 5.

[0116] Step 7: The sealing cover device 6 presses the cover into the lock cylinder hole of the lock body, sealing the lock cylinder inside the lock cylinder hole, completing the assembly of the four-way padlock, and ending the step.

[0117] The method for assembling the lock cylinder in step 6 includes the following steps:

[0118] Step 61: The vibrating feeding tray transports the locking plates to the vibrating screening channel;

[0119] Step 62: The conveying channel 7112 in the vibration screening channel transmits the locking pieces forward by vibration; wherein the superimposed locking pieces and the locking pieces placed on the reverse side vibrate away from the conveying channel 7112 above the first column edge 7113; the locking pieces placed on the front side move along the first column edge 7113 to the area corresponding to the second column edge 7114;

[0120] Step 63: The locking plate passes through the second column edge 7114 and exits the vibration screening channel into the passage slot 7121;

[0121] Step 64: The first moving part 7122 moves to move the first straight rod 7127 on the first rotating part 7125 to above the locking piece at the entrance of the passage slot 7121;

[0122] Step 65: The second moving part 7123 moves to press down the first rotating part 7125; at the same time, the first rotating part 7125 rotates, driving the first straight rod 7127 on the first rotating part 7125 to rotate until the first straight rod 7127 is aligned with the through hole on the lock piece, and the first straight rod 7127 passes through the through hole on the lock piece.

[0123] Step 66: The first moving part 7122 is activated, causing the first straight rod 7127 to drive the locking piece to move along the through groove 7121 to the proximity sensor 7126.

[0124] Step 67: The proximity sensor 7126 senses whether the protrusion on the lock plate is located on one side of the proximity sensor 7126; if the protrusion on the lock plate is located on one side of the proximity sensor 7126, the lock plate is considered to be in the correct direction, and proceed to the next step; if the protrusion on the lock plate is located on the side away from the proximity sensor 7126, the lock plate is considered to be in the opposite direction, the second moving member 7123 is activated to separate the lock plate and the first straight rod 7127, and the third moving member 7124 is activated to push the lock plate away from the through slot 7121, and return to step 61;

[0125] Step 68: The locking plate is in the correct direction. First, the second moving part 7123 moves to separate the locking plate and the first straight rod 7127. Then, the first moving part 7122 moves to send the first straight rod 7127 back to the part near the entrance of the passage slot 7121 and moves the second straight rod 7128 above the locking plate.

[0126] Step 69: The second moving part 7123 is activated, inserting the second straight rod 7128 into the corresponding through hole on the lock plate;

[0127] Step 610: The first moving part 7122 is activated, and the second straight rod 7128 carries the locking piece away from the through slot 7121 and into the delivery structure 713, returning to step 61.

[0128] It should be noted that when the second straight rod 7128 moves the locking piece away from the proximity sensor 7126 in step 69, the first straight rod 7127 can simultaneously move the locking piece from the front end of the passage slot 7121 to the proximity sensor 7126, thereby improving efficiency.
