Description

Technical Field

[0001] This invention relates to the field of padlock manufacturing equipment, and in particular to a lock cylinder directional assembly structure and assembly method. Background Technology

[0002] The lock cylinder of a padlock includes several lock plates, each of which is circular. A through hole for inserting a key is located in the center of each plate, and the edges of each plate have arc-shaped notches for locking with a steel ball and a small raised portion. Existing lock plates typically have a front and a back. In this application, the flat side of the lock plate is designated as the back, and the side with the arc-shaped transition edge is designated as the front. Since the front and back, as well as the orientation of the raised portion and the arc-shaped notch, need to be distinguished during lock plate installation, verification is required during lock cylinder assembly. For example, the solution shown in patent CN109396835B uses a lock pin positioning and correction mechanism for positioning. However, this only ensures that the third pressing correction rod passes through the hole on the lock pin, but it cannot guarantee the orientation and front / back of the lock pin. Therefore, an assembly structure and method are needed that can accurately orient the lock plates of the lock cylinder. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a lock cylinder locking plate orientation assembly structure and assembly method.

[0004] To solve the above problems, the present invention adopts the following technical solution:

The first cylinder is fixedly mounted on the movable end of the second cylinder, and moves with the movement of the first cylinder. The second cylinder is located in the vertical direction. The movable end of the second cylinder is fixedly equipped with a first rotating component and a second straight rod. The first rotating component is located on the side near the entrance of the passageway, and the second straight rod is located on the side near the exit of the passageway. The first rotating component includes a motor for rotation, and the first straight rod is mounted on the shaft of the motor. A proximity sensor for detecting protrusions on the lock plate is also installed in the passageway. A third cylinder for pushing the lock plate away from the passageway is also installed in the passageway, and the third cylinder is correspondingly mounted to the proximity sensor.

[0006] Furthermore, the vibration conveying structure includes a vibratory feeding tray for sequentially conveying the locking plates.

[0007] Furthermore, the vibration conveying structure also includes a vibration screening channel; the vibration screening channel is disposed between the inlet of the vibration feeding tray and the through groove; the vibration screening channel includes a vibration device, a conveying channel for vibrating and conveying the locking pieces, a first guardrail for screening the front and back sides of the locking pieces, and a second guardrail for ensuring the passage of the locking pieces; wherein the conveying channel is connected to the vibration device for controlling its vibration; the first guardrail and the second guardrail protrude and are disposed on the same side of the conveying channel, the first guardrail and the second guardrail are connected, and the first guardrail is located at the end of the second guardrail near the vibration feeding tray; the side of the conveying channel near the first guardrail and the second guardrail is inclined downward at a set angle to ensure that the locking pieces move forward along the first guardrail or the second guardrail; the height of the protrusion of the first guardrail is lower than that of the second guardrail, and the height of the protrusion of the first guardrail is a set value.

[0008] Furthermore, a limiting block for the passage of the locking piece is provided at one end of the transport channel near the through slot. There is a gap between the limiting block and the transport channel for the locking piece to pass through. The limiting block is located on the side of the transport channel away from the first and second railings.

[0009] Furthermore, the limiting block is a cylinder, and the axis of the cylinder is consistent with the transport direction of the transport channel.

[0010] Furthermore, the side of the passageway is provided with an ejection port, which is located between the inlet and outlet of the passageway and is correspondingly provided with the third cylinder; the third cylinder is located on the side of the passageway.

[0011] Furthermore, the passageway includes a first through slot for passing through the locking piece and a second through slot for extending into the first straight rod and the second straight rod; the second through slot is located at the bottom of the first through slot; the width of the second through slot is smaller than the width of the first through slot.

[0012] Furthermore, the first through slot of the passageway is L-shaped; the portion of the first through slot that connects to the transport channel is configured as an inclined surface corresponding to the transport channel.

[0013] Furthermore, the locking plate orientation structure also includes a second rotating member, which is located between the movable end of the second cylinder and the second straight rod; the second straight rod is disposed on the rotating shaft of the second rotating member.

[0014] A method for orienting the locking plate of a lock cylinder, the method being based on the aforementioned orienting locking plate assembly structure; the method includes the following steps:

[0015] Step 1: The vibrating feeder transports the locking plates to the vibrating screening channel;

[0016] Step 2: The conveyor channel in the vibration screening channel transmits the locking plates forward through vibration; the stacked locking plates and the locking plates placed on the reverse side vibrate away from the conveyor channel above the first column edge; the locking plates placed on the front side move along the first column edge to the corresponding area of ​​the second column edge;

[0017] Step 3: The locking plate passes through the second column side and exits the vibration screening channel into the passageway;

[0018] Step 4: The first cylinder actuates, moving the first straight rod on the first rotating part above the locking plate at the entrance of the passage slot;

[0019] Step 5: The second cylinder actuates, pressing down the first rotating part; at the same time, the first rotating part rotates, driving the first straight rod on the first rotating part to rotate until the first straight rod is aligned with the through hole on the lock piece, and the first straight rod passes through the through hole on the lock piece;

[0020] Step 6: The first cylinder actuates, causing the first straight rod to move the locking plate along the through groove to the proximity sensor.

[0021] Step 7: The proximity sensor detects whether the protrusion on the locking plate is located on one side of the proximity sensor; if the protrusion on the locking plate is located on one side of the proximity sensor, the locking plate is considered to be in the correct direction, and proceed to the next step; if the protrusion on the locking plate is located on the side away from the proximity sensor, the locking plate is considered to be in the opposite direction, the second cylinder is activated to separate the locking plate from the first straight rod, and the third cylinder is activated to push the locking plate away from the through slot, returning to step 1;

[0022] Step 8: With the locking plate in the correct direction, the second cylinder first activates to separate the locking plate from the first straight rod. Then, the first cylinder activates to send the first straight rod back to the position near the entrance of the passageway and moves the second straight rod above the locking plate.

[0023] Step 9: The second cylinder actuates, inserting the second straight rod into the corresponding through hole on the lock plate;

[0024] Step 10: The first cylinder actuates, and the second straight rod pulls the locking plate away from the through slot and into the delivery structure, returning to step 1.

[0025] The beneficial effects of this invention are as follows:

[0026] By setting up proximity sensors in conjunction with a third cylinder, the orientation of the locking plates can be detected, ensuring that the locking plates transported to the second straight rod are in the same orientation.

[0027] By setting up a vibration screening channel, including an inclined conveying channel, and cooperating with a first column edge of a set height, the stacked and reversed locking pieces are screened and removed from the conveying channel;

[0028] By setting a limit block at the end of the transport channel, the movement space of the locking piece is restricted, and its movement along a set trajectory is controlled.

[0029] By setting an upper pressure block on the through slot, with a gap between the upper pressure block and the through slot, one purpose is to restrict the passage of the locking piece and prevent the locking pieces from overlapping. It can also reduce the shaking and rotation of the locking piece when the first straight rod and the locking piece separate.

[0030] By setting the first through slot and the second through slot to overlap, on the one hand, it can be ensured that the first straight rod and the second straight rod can effectively pass through the locking piece, and on the other hand, it can also limit the angle when the first straight rod and the second straight rod pass through the locking piece to a certain extent, limiting the orientation of the locking piece controlled by the rotation of the first straight rod to only two directions;

[0031] By setting the first through slot to be L-shaped, the locking piece can stop at the corner of the L-shaped first through slot and wait for the first straight rod;

[0032] By setting the part connecting the first through groove and the conveying channel as an inclined surface corresponding to the conveying channel, it is convenient for the conveying channel and the first through groove to dock, so that the locking piece can smoothly transition from the conveying channel to the through groove. In addition, the inclined surface is inclined towards the side away from the exit of the through groove, so that the locking piece can be stuck at the corner of the first through groove.

[0033] By setting the ends of the first and second straight rods near the through slot to be rounded, it is easier for them to be inserted into the through holes on the lock plate.

[0034] By setting the delivery structure to include a first limiting structure and a second limiting structure, the lock piece fitted on the third straight rod can pass through the first limiting structure and the second limiting structure in sequence, achieving a phased descent, which facilitates the control of the lock pieces being installed into the lock cylinder one by one in subsequent processes.

Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0050] 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.

[0051] Example 1:

[0052] like Figures 1-13 As shown, a lock cylinder's slab orientation assembly structure includes a vibration transmission structure 1 for transporting the slab 4. It should be noted that in this example, the slab 4 is generally circular, with rounded edges on the front and a flat back. The edges of the slab 4 also have arc-shaped notches and semi-circular protrusions, and the central area of ​​the slab 4 has a through hole of a predetermined size. The assembly structure also includes a slab orientation structure 2 connected to the vibration transmission structure 1 and a feeding structure 3 for feeding the slab 4 to subsequent processes. The locking plate orientation structure 2 includes a through slot 21 for the passage of the locking plate 4, a first cylinder 22, a second cylinder 23, a third cylinder 24, a first rotating member 25, a proximity sensor 26, and a first straight rod 27 and a second straight rod 28 for fitting the locking plate 4. The cross-sectional shapes of the first straight rod 27 and the second straight rod 28 correspond to the shapes of the through holes on the locking plate 4. The inlet of the through slot 21 is connected to the outlet of the vibration transmission structure 1. The outlet of the through slot 21 is connected to the delivery structure 3. The first cylinder 22 is fixedly installed in the through slot 21. Above, the movement direction of the first cylinder 22 is consistent with the movement direction of the locking piece 4 in the passageway 21; the second cylinder 23 is fixedly disposed at the movable end of the first cylinder 22, and the second cylinder 23 moves with the movement of the first cylinder 22; the second cylinder 23 is located in the vertical direction; the movable end of the second cylinder 23 is fixedly disposed with a first rotating member 25 and a second straight rod 28, the first rotating member 25 is located on the side near the entrance of the passageway 21, and the second straight rod 28 is located on the side near the exit of the passageway 21; the first rotating member 25 includes components for rotating... A motor is installed, and a first straight rod 27 is installed on the motor shaft. The first straight rod 27 and the second straight rod 28 are reciprocated along the direction of the through groove 21 by a first cylinder 22, and the first straight rod 27 and the second straight rod 28 are moved closer to and away from the through groove 21 by a second cylinder 23. A proximity sensor 26 for detecting the protrusion on the lock piece 4 is also installed in the through groove 21. A third cylinder 24 for pushing the lock piece 4 away from the through groove 21 is also installed in the through groove 21, and the third cylinder 24 is correspondingly installed with the proximity sensor 26.

[0053] The vibration conveying structure 1 includes a vibration feeding tray for sequentially conveying the locking plates 4; it should be noted that the vibration feeding tray uses an existing device, which is not shown in the attached drawings. The vibration conveying structure 1 also includes a vibration screening channel; the vibration screening channel is located between the entrance of the vibration feeding tray and the through groove 21; the vibration screening channel includes a vibration device 11, a conveying channel 12 for vibrating and conveying the locking piece 4, a first guardrail 13 for screening the front and back sides of the locking piece 4, and a second guardrail 14 for ensuring the passage of the locking piece 4; wherein the conveying channel 12 is connected to the vibration device 11 for controlling its vibration; the first guardrail 13 and the second guardrail 14 protrude and are located on the same side of the conveying channel 12, the first guardrail 13 and the second guardrail 14 are connected, and the first guardrail 13 is located at the end of the second guardrail 14 near the vibration feeding tray; the side of the conveying channel 12 near the first guardrail 13 and the second guardrail 14 is tilted downward at a set angle to ensure that the locking piece 4 moves forward along the first guardrail 13 or the second guardrail 14; the height of the protrusion of the first guardrail 13 is lower than that of the second guardrail 14, and the height of the protrusion of the first guardrail 13 is a set value. Since the transport channel 12 is inclined, the locking plate 4 vibrating forward in the transport channel 12 will abut against the first rail edge 13 or the second rail edge 14. The front edge of the locking plate 4 is rounded. With the first rail edge 13 at a set height, it will pass over the first rail edge 13 and leave the transport channel 12 as it vibrates. In addition, the locking plate 4 located at the top of the stacked locking plates 4 will also leave the transport channel 12 from the first rail edge 13.

[0054] The transport channel 12 is also provided with a limiting block 15 for the passage of the locking piece 4 at one end near the through slot 21. There is a gap between the limiting block 15 and the transport channel 12 for the locking piece 4 to pass through. The limiting block 15 is located on the side of the transport channel 12 away from the first rail edge 13 and the second rail edge 14. In this example, the limiting block 15 is a cylinder, and the axis of the cylinder is consistent with the transport direction of the transport channel 12.

[0055] The side of the through slot 21 is provided with a push-out port 29, which is located between the inlet and outlet of the through slot 21 and is correspondingly provided with the third cylinder 24. The third cylinder 24 is located on the side of the through slot 21. The action of the third cylinder 24 can push the locking piece 4 away from the through slot 21 through the push-out port 29 on the side of the through slot 21. The through slot 21 is also provided with an upper pressure block 213. A gap is provided between the upper pressure block 213 and the through slot 21 to restrict the passage of the locking piece 4, prevent the locking piece 4 from overlapping, and reduce the shaking and rotation of the locking piece 4 when the first straight rod 27 and the locking piece 4 are separated. In this example, the upper pressure block 213 and the through slot 21 are integrally made. A hollow strip structure is provided on the side of the upper pressure block 213 near the through slot 21 as a gap.

[0056] The through slot 21 includes a first through slot 211 for the passage of the locking piece 4 and a second through slot 212 for the insertion of the first straight rod 27 and the second straight rod 28. The second through slot 212 is located at the bottom of the first through slot 211. The width of the second through slot 212 is smaller than the width of the first through slot 211. By setting the second through slot 212, when the first straight rod 27 and the second straight rod 28 are inserted into the through hole on the locking piece 4, they can continue to extend to the bottom of the second through slot 212. This ensures that the first straight rod 27 and the second straight rod 28 can effectively pass through the locking piece 4. It also limits the angle at which the first straight rod 27 and the second straight rod 28 pass through the locking piece 4 to a certain extent. In this example, the width of the second through slot 212 corresponds to the width of the first straight rod 27 and the second straight rod 28, so that the first straight rod 27 and the second straight rod 28 can only be inserted into the second through slot 212 when their width direction is aligned with the second through slot 212. This limits the orientation of the locking piece 4 controlled by the rotation of the first straight rod 27 to only two directions.

[0057] The first through groove 211 of the passageway 21 is L-shaped, allowing the locking piece 4 to stop at the corner of the L-shaped first through groove 211, waiting for the action of the first straight rod 27. This prevents the locking piece 4 from being squeezed into the passageway 21 due to excessive vibration transmission, which would affect the action of the proximity sensor 26, the first straight rod 27, the second straight rod 28, etc. It also facilitates the insertion of the first straight rod 27 into the through hole on the locking piece 4. In this example, the part of the first through groove 211 that connects to the transport channel 12 is set as an inclined surface corresponding to the transport channel 12, which facilitates the docking between the transport channel 12 and the first through groove 211, allowing the locking piece 4 to smoothly transition from the transport channel 12 into the passageway 21. It should be noted that the inclined surface in the first through groove 211 is inclined towards the side away from the outlet of the passageway 21, further facilitating the locking piece 4 to be locked at the corner of the first through groove 211.

[0058] The locking plate orientation structure 2 also includes a second rotating member 210, which is located between the movable end of the second cylinder 23 and the second straight rod 28. The second straight rod 28 is disposed on the rotating shaft of the second rotating member 210, so that the second straight rod 28 can be better inserted into the through hole on the locking plate 4.

[0059] The ends of the first straight rod 27 and the second straight rod 28 near the through slot 21 are also rounded to facilitate their insertion into the through hole on the lock piece 4.

[0060] The delivery structure 3 includes a fixedly installed third straight rod 31, a first limiting structure 32, and a second limiting structure 33. The third straight rod 31 is vertically installed at the exit of the passageway 21. The first limiting structure 32 and the second limiting structure 33 are both finger cylinders. The first limiting structure 32 and the second limiting structure 33 are fixedly installed at predetermined heights on the third straight rod 31. By setting the first limiting structure 32 and the second limiting structure 33, the locking piece 4 fitted on the third straight rod 31 can pass through the first limiting structure 32 and the second limiting structure 33 in sequence, achieving a staged descent, which facilitates the control of the locking piece 4 being installed into the lock cylinder piece by piece in subsequent processes.

[0061] The proximity sensor 26 is a conventional photoelectric sensor or infrared sensor that can detect the approach of an object. To avoid interference, a through sensor detection hole 214 is provided at a set position in the passageway 21. When the locking piece 4 passes through and stops at the set position, the protrusion on the upright locking piece 4 faces the top of the sensor detection hole 214. The proximity sensor 26 inside the sensor detection hole 214 senses that an object has passed through and stopped above the sensor detection hole 214, thus realizing the orientation detection of the locking piece 4.

[0062] A method for orienting the locking plate of a lock cylinder, the method being based on the aforementioned orienting locking plate assembly structure; the method includes the following steps:

[0063] Step 1: The vibrating feeding tray transports the locking plate 4 to the vibrating screening channel;

[0064] Step 2: The conveying channel 12 in the vibration screening channel transmits the locking piece 4 forward by vibration; wherein the superimposed locking piece 4 and the locking piece 4 placed on the reverse side vibrate away from the conveying channel 12 from above the first column edge 13; the locking piece 4 placed on the front side moves along the first column edge 13 to the area corresponding to the second column edge 14.

[0065] Step 3: Locking plate 4 passes through the second column side 14 and exits the vibration screening channel into the passage groove 21;

[0066] Step 4: The first cylinder 22 is activated, moving the first straight rod 27 on the first rotating part 25 to above the locking piece 4 at the entrance of the through slot 21;

[0067] Step 5: The second cylinder 23 is activated, pressing down the first rotating part 25; at the same time, the first rotating part 25 rotates, driving the first straight rod 27 on the first rotating part 25 to rotate until the first straight rod 27 is aligned with the through hole on the locking plate 4, and the first straight rod 27 passes through the through hole on the locking plate 4.

[0068] Step 6: The first cylinder 22 is activated, causing the first straight rod 27 to drive the locking piece 4 to move along the through groove 21 to the proximity sensor 26.

[0069] Step 7: The proximity sensor 26 senses whether the protrusion on the locking plate 4 is located on one side of the proximity sensor 26; if the protrusion on the locking plate 4 is located on one side of the proximity sensor 26, the locking plate 4 is considered to be in the correct direction, and proceed to the next step; if the protrusion on the locking plate 4 is located on the side away from the proximity sensor 26, the locking plate 4 is considered to be in the opposite direction, the second cylinder 23 is activated to separate the locking plate 4 from the first straight rod 27, and the third cylinder 24 is activated to push the locking plate 4 away from the through slot 21, and return to step 1;

[0070] Step 8: With the locking plate 4 in the correct direction, the second cylinder 23 first activates to separate the locking plate 4 from the first straight rod 27. Then, the first cylinder 22 activates to send the first straight rod 27 back to the position near the entrance of the passage slot 21 and move the second straight rod 28 above the locking plate 4.

[0071] Step 9: The second cylinder 23 is activated, inserting the second straight rod 28 into the corresponding through hole on the locking plate 4;

[0072] Step 10: The first cylinder 22 is activated, and the second straight rod 28 takes the locking piece 4 away from the through slot 21 and sends it into the delivery structure 3, returning to step 1.

[0073] It should be noted that when the second straight rod 28 moves the locking piece 4 away from the proximity sensor 26, the first straight rod 27 can simultaneously move the locking piece 4 from the front end of the passage slot 21 to the proximity sensor 26, thus improving efficiency.

[0074] During implementation, proximity sensors 26, in conjunction with a third cylinder 24, are used to detect the orientation of the locking plates 4, ensuring that the locking plates 4 transported to the second straight rod 28 have the same orientation. A vibration screening channel, including an inclined transport channel 12 and a first railing 13 at a set height, is used to screen stacked and reversed locking plates 4, causing them to leave the transport channel 12. A limiting block 15 is set at the end of the transport channel 12 to restrict the movement space of the locking plates 4 and control their movement along a set trajectory. An upper pressure block 213 is set on the through slot 21, with a gap between the upper pressure block 213 and the through slot 21. This serves two purposes: firstly, to restrict the passage of the locking plates 4, preventing them from stacking, and secondly, to reduce the shaking and rotation of the locking plates 4 when the first straight rod 27 separates from the locking plates 4. The overlapping of the first through slot 211 and the second through slot 212 ensures that the first straight rod 27 and the second straight rod 28 effectively pass through the locking plates 4, and also limits the angle at which the first straight rod 27 and the second straight rod 28 pass through the locking plates 4 to a certain extent. The locking plate 4, which restricts the rotation of the first straight rod 27, can only be oriented in two directions. By setting the first through groove 211 to be L-shaped, the locking plate 4 can stop at the corner of the L-shaped first through groove 211. By setting the part of the first through groove 211 that connects to the transport channel 12 to be an inclined surface corresponding to the transport channel 12, it is convenient for the transport channel 12 and the first through groove 211 to dock, so that the locking plate 4 can smoothly transition from the transport channel 12 to the through groove 21. In addition, the inclined surface faces away from the outlet of the through groove 21. The first straight rod 27 and the second straight rod 28 are tilted to one side, which makes it easy for the locking piece 4 to be locked in the corner of the first through groove 211. The first straight rod 27 and the second straight rod 28 are rounded at the end near the through groove 21, which makes it easy for them to be inserted into the through hole on the locking piece 4. The delivery structure 3 includes a first limiting structure 32 and a second limiting structure 33, so that the locking piece 4 sleeved on the third straight rod 31 can pass through the first limiting structure 32 and the second limiting structure 33 in sequence, so as to achieve a staged drop, which makes it easy to control the locking piece 4 to be installed into the lock cylinder one by one in the subsequent process.

[0075] The above description is merely a specific example of the present invention and does not constitute any limitation on the present invention. Obviously, those skilled in the art, after understanding the content and principles of the present invention, may make various modifications and changes in form and detail without departing from the principles and structure of the present invention; however, these modifications and changes based on the spirit of the present invention are still within the scope of protection of the claims of the present invention.
