Description

Technical Field

[0001] The invention relates to the technical field of lock core assembly equipment, in particular to automatic assembly equipment for a single-opening lock core. Background Art

[0002] Existing single-opening lock cylinder, such as Figures 1 to 3 As shown, it usually includes a lock sleeve a, a lock core b, a central rotor c, a rotating dial d, a thumb turner e, a spring f and a retaining spring g, wherein the lock sleeve a is provided with a penetrating lock cavity a1 and a notch groove a2 in the middle thereof that divides the lock cavity a1 into two parts, the lock core b has a key hole b1 for the key to pass through, the central rotor c has a rotor groove c1 that matches the tail of the key and a sheet-like rotor insert c2 is formed on its upper end, the end of the thumb turner e is formed with a knob e1 of a characteristic shape (such as a columnar, square, etc.) and the other end thereof is provided with an inner cavity e2 with an opening, and the lock core The end of b away from the opening of the keyhole b1 and the end of the thumb turner e away from the knob e1 are both provided with a snap ring groove h that cooperates with the retaining spring, the lock sleeve a has a protrusion a3 protruding axially along the lock cavity a1, the rotating dial d has an engaging portion d1 protruding along its axial direction and adapted to the shape of the protrusion a3, the engaging portion d1 is used to engage with the locking mechanism (the lock core matches the locking mechanism), and the rotating dial d is penetrated along its axial direction to provide an insert slot d2 that cooperates with the rotor insert c2, so that when the rotor insert c2 is inserted, it can drive the rotating dial d to rotate synchronously.

[0003] During the assembly process, first place the rotating dial d into the corresponding notch a2 in the middle of the lock sleeve a, so that it remains coaxial with the lock cavity a1 on both sides of the notch a2 on the lock sleeve a. Subsequently, insert the center rotor c and the lock core b in sequence along one side of the lock cavity a1, and the center rotor c penetrates the rotating dial d to achieve the coaxial linkage between the lock core b and the rotating dial d. Subsequently, place the spring f into the inner cavity e2 of the finger turner e, and then insert the finger turner e along the other side of the lock cavity a1, and let the end of the center rotor c penetrate into the inner cavity e2 of the finger turner e, so as to ensure the coaxial linkage relationship between the lock core b, the center rotor c, the rotating dial d and the finger turner e. Finally, install the retaining spring g at the two gaps of the notch a2 to limit the axial movement of the lock core b and the finger turner e to prevent them from dislocation.

[0004] When the correct key is inserted into the keyhole of the lock cylinder, it can drive the lock cylinder, center rotor, rotating dial and thumb turner to rotate synchronously, thereby opening the door lock. Due to its compact design and good security, it has been widely used in the market, especially as a lock cylinder for interior doors.

[0005] However, the current assembly of single-opening lock cylinders mostly relies on semi-automatic or manual methods and is completed using specific assembly tools, resulting in low production efficiency.

[0006] In addition, due to the structure of the single-opening lock core, it is impossible to assemble it on both sides after placing it horizontally like a double-opening lock core. The difficulties in its automated assembly mainly focus on the two aspects of positioning accuracy and assembly stability, so there is still room for improvement.

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] See also Figures 1 to 16 , is an automatic assembly device for a single-opening lock core as the best embodiment of the present invention, including a tool, a conveying device, a lock core assembly mechanism, a central rotor assembly mechanism, a lock sleeve assembly mechanism, a first retaining spring assembly mechanism, a thumb turner feeding mechanism, a spring feeding mechanism, a flipping mechanism and a second retaining spring assembly mechanism, which are specifically as follows: like Figure 5 As shown, the tooling has a forward fixing position and a reverse fixing position, the forward fixing position is provided with a limiting piece matched with the key hole, and the reverse fixing position is provided with a knob limiting groove matched with the knob limiting position at the end of the thumb turner; Specifically, in this embodiment, the tooling includes a square sheet-shaped base, one side of the upper end surface of the base is fixed with another square-shaped fixing seat, the fixing seat is recessed downward to form a knob limiting groove that fits with the shape of the knob of the thumb turner, the limiting plate is integrally fixed to the top surface of the base and is located on one side of the fixing seat, the limiting plate is a sheet-shaped insert structure, and its purpose is to simulate a universal key so that it can be smoothly inserted into the keyhole of the lock core, and the lock core is limited through the keyhole, so that the lock core maintains a posture perpendicular to the base, which is convenient for subsequent assembly of parts such as the lock sleeve, center rotor and retaining spring based on this.

[0024] like Figure 5 As shown, a pair of limiting structures are provided on the upper end surface of the base and on one side of the limiting plate, and a limiting area with an upper end opening formed between the two limiting structures and in contact with the outer wall of the lock sleeve to limit its swing. In this embodiment, the limiting structure is a pair of limiting shafts, which are symmetrically distributed about the limiting plate. The limiting area between the two limiting shafts allows the protrusions on the side of the lock sleeve to be just inserted. If there is no limiting structure, the lock sleeve is in a state of being able to rotate relative to the axial direction of the lock sleeve after being inserted into the lock core. Therefore, adding a limiting structure can cooperate with the lock core positioned by the limiting plate to limit and fix the lock sleeve as a whole, thereby facilitating the subsequent assembly process.

[0025] like Fig.16 As shown, the conveying device is used to drive the tooling to cyclically convey along a closed rotary path; like Figure 6 , 7As shown, the lock core assembly mechanism is used to grab the lock core to the positive fixed position and allow the key hole to be inserted into the limit plate to maintain a vertical posture; Specifically, in the present embodiment, the lock gall assembly mechanism includes a lock gall upper material position, a first swinging device, a first lifting device, a first clamping device and a first lifting device. The first lifting device is used to vertically lift a single lock gall from the lock gall upper material position. The first clamping device is used to grab the single lock gall after being lifted. The first swinging device is used to swing the first clamping device along a circular path to above the tooling at a corresponding position and make the lock hole of the lock gall face the limit plate. The first lifting device is used to drive the first clamping device to lift vertically up and down so that the lock gall is inserted into the limit plate and fixed in position.

[0026] In this embodiment, the lock core loading position is carried out by a vibration plate cooperating with a straight vibration track to load the lock core, and it is transported to the lock core loading position at the end of the straight vibration track. It can also be loaded manually with the straight vibration track, which is not limited here. When the lock core is loaded, its keyhole is located in an upward direction so that the opening at the other end of the lock core faces downward.

[0027] In addition, the first lifting device is a linear cylinder, and a rotating motor is fixed to the end of the cylinder through a moving seat. A push rod is coaxially fixed on the output shaft of the rotating motor. The push rod is directly below the material level on the lock core. The push rod is designed to be able to penetrate into the diameter of the opening at the lower end of the lock core, and an opening for the push rod to penetrate is opened on the bottom surface of the end of the straight vibration track. Therefore, when the cylinder drives the moving seat and the rotating motor to extend and retract, the push rod penetrates into the opening below the lock core in the vertical direction to lift the lock core to a high position, which is convenient for the subsequent clamping and movement of the lock core. During this process, if it is detected that the keyhole of the lock core is inconsistent with the direction of the limit plate on the tooling, the rotating motor is used for rotation correction so that the lock core can be inserted into the limit plate in the correct posture for limit fixing.

[0028] In this embodiment, the first clamping claw device is a finger cylinder, which has a pair of openable and closable clamping fingers, and clamping grooves adapted to the shape of the lock core are symmetrically provided between the two clamping fingers, so that the lock core can be clamped stably. When the cylinder drives the motor to lift the lock core to a high position, the clamping fingers of the finger cylinder move to the two sides of the lock core in an open posture, and then the clamping fingers close, the lock core is stuck in the clamping groove, the cylinder drives the motor to retract, the push rod descends and disengages from the lock core and returns to the position below the straight vibration track to wait for the next lifting.

[0029] In this embodiment, the first swinging device is a rotary cylinder, which has a first output disk (not marked in the figure) that can rotate and swing in a circular direction. The first clamping device is fixed on the first output disk, and the range of the finger cylinder swing driven by the first output disk is limited to the high position where the lock core is lifted and clamped and the position directly above the limit plate facing the tooling. The first output disk corresponding to the above two positions is rotated exactly 180°. During this process, the keyhole of the lock core is rotated and swung from the positive upward direction to the reverse downward position facing the limit plate.

[0030] Furthermore, the first lifting device is also a linear cylinder, and the rotating cylinder is fixed as a whole on the output shaft of the linear cylinder, so that the rotating cylinder, the finger cylinder and the lock core are driven to rise and fall synchronously through the first lifting device. After the lock core is moved to the top of the tooling, the lock core is driven down by the first lifting device, so that the keyhole of the lock core can be smoothly inserted into the limit plate. Finally, the finger cylinder releases the lock core, and the first lifting device drives the finger cylinder and the rotating cylinder to rise, and the rotating cylinder rotates to the initial position, completing the loading process of the lock core.

[0031] In addition, a limit block is provided directly above the upper material position of the lock core. The limit block is controlled to retract and extend by a linear block cylinder. When the limit block is extended to directly above the upper material position of the lock core, the lock core is driven by the first lifting device to move to the position where the lock core just contacts the limit block. This position is the high position after the lock core is lifted, and then the limit block retracts to avoid affecting the movement trajectory of the swing cylinder and the finger cylinder.

[0032] Subsequently, the tooling, with the limited locking core, is transported by the conveying device into the range of the central rotor assembly mechanism.

[0033] like Figure 8 As shown, the center rotor assembly mechanism is used to grab the center rotor onto the top of the lock core on the tooling so that the rotor slot of the center rotor is limitedly matched with the limit plate; Specifically, the center rotor assembly mechanism includes a center rotor upper material position, a second lifting device, a first biaxial removal device and a first rotating device. The second lifting device is used to lift individual center rotors from the center rotor upper material position one by one. The first biaxial removal device is used to grab the center rotor from the center rotor upper material position to the top of the tooling at the corresponding position and make the rotor slot of the center rotor insert into the limit plate directly below it. The first rotating device is used to drive the center rotor to rotate and make the rotor slot parallel to the limit plate to achieve smooth insertion of the rotor slot and the limit plate.

[0034] In this embodiment, the center rotor loading position is also loaded through a vibration plate in cooperation with a straight vibration track. The conveying end of the straight vibration track forms the loading position of the center rotor. During the center rotor loading process, its rotor slot is in the positive downward direction, and the rotor insert is in the positive upward position. The second jacking device is a linear cylinder, and a mold base is fixed at its output end. A accommodating groove that just accommodates a single center rotor is formed on the side of the mold base close to the center rotor loading position. After the center rotor enters the accommodating groove along the straight vibration, the rotor insert at its upper end is located at the upper end and protrudes from the upper end surface of the mold base for easy grasping. The second jacking device rises and drives the center rotor to rise vertically.

[0035] The cam is an air cylinder that is fixed to the bottom of the second sliding seat, and the cam is used to move the first and second sliding seats, so that the cam can move upwards and downwards, thereby realizing the vertical movement of the second sliding seat. The claw is located in a vertical downward position, so that the first double-axis removing device can drive the first clamping cylinder to move back and forth between the center rotor loading position and the lock gall opening position on the tooling. When the second jacking device lifts the center rotor, the first clamping cylinder moves to the rotor insert position of the center rotor under the drive of the double-axis removing device, and the two first clamping jaws of the first clamping jaw cylinder are closed so that the rotor insert is embedded in the insert clamping groove. Then the second jacking device descends, and the first double-axis removing device moves the first clamping jaw cylinder together with the center rotor fixed thereon to directly above the lock gall on the tooling. At this time, the rotor groove below the center rotor is opposite to the limit plate on the inner side of the lock gall opening. The first lifting cylinder drives the center rotor to descend so that the rotor groove at its lower end is inserted into the limit plate in the lock gall opening. Finally, the two first clamping jaws are released, raised and reset, completing the loading, removing and assembly process of the center rotor.

[0036] Among them, the first rotating device is used to adjust the direction of the first clamping jaw in the above process so that the insert clamping groove can face the rotor insert of the center rotor, so as to facilitate the first clamping jaw cylinder to clamp the center rotor; at the same time, during the assembly of the center rotor, the direction of the center rotor can also be rotated and adjusted so that the rotor slot of the center rotor can face the limit plate in parallel, so as to facilitate the smooth insertion of the center rotor into the limit plate in the lock core on the tooling.

[0037] Subsequently, the tooling, with the limited lock core and the center rotor, enters the range of the lock assembly mechanism under the transmission of the transmission device.

[0038] like Fig. 9 , 10 As shown, the lock sleeve assembly mechanism is used to grab the lock sleeve with the rotating dial wheel and vertically insert the lock cavity into the central rotor and the lock core in sequence, and when the lock sleeve is inserted, the central rotor is inserted into the rotating dial wheel to achieve synchronous rotation; Specifically, the lock sleeve assembly mechanism includes a removal jig, a rotating dial feeding device, a lock sleeve feeding device, a second swinging device, a first pushing device and a second biaxial removal device. The removal jig has a linear removal groove and a first limiting groove located below the removal groove and engaged with the protrusion and the engaging portion. The lock sleeve feeding device is used to remove the lock sleeves one by one to the first limiting groove of the removal jig and make the protrusion of the lock sleeve snap into the first limiting groove. The rotating dial feeding device is used to remove the rotating dial one by one to the notch of the lock sleeve on the removal jig. The first double-axis removing device is used to remove the lock sleeve and the rotating dial wheel in the vertical position and insert them into the tooling above the corresponding position so that the lock sleeve and the rotating dial wheel are aligned with the limit plate.

[0039] In this embodiment, the removal jig is in the shape of a long strip as a whole, and a wider removal groove is first opened at its upper end, which is used to cooperate with the main part of the locking sleeve and the main part of the rotating dial wheel to achieve limiting. The center position of the removal groove continues to descend and recess to form a first limiting groove. The width of the first limiting groove is adapted to the protruding portion of the locking sleeve and the meshing portion of the rotating dial wheel. When the locking sleeve is placed into the removal jig from above, its main part is limited by the removal groove, and its protruding portion is just inserted into the first limiting groove. At this time, the notch groove of the locking sleeve is located on the upper side of the removal groove, and the rotating dial wheel can be placed into the locking sleeve from the notch groove, and the main part of the rotating dial wheel is also limited by the removal groove, and the meshing portion at its lower end is correspondingly placed in the first limiting groove, so that the locking sleeve and the rotating dial wheel finally maintain a consistent posture on the removal jig.

[0040] In addition, in order to achieve synchronous movement of the locking sleeve and the rotating dial wheel in the removal groove, the first pushing device is a linear cylinder, and a U-shaped toggle plate is fixed to the end of its output shaft, and the toggle plate has a toggle portion adapted to the first limit groove. In order to cooperate with the toggle plate, the removal groove and the first limit groove are both through-connected on both sides along the length direction, and the initial position of the toggle plate is located on one side of the removal groove. Therefore, when the first pushing device is extended or retracted, the toggle portion of the toggle plate moves along the first limit groove, and the locking sleeve and the rotating dial wheel are synchronously moved to the other side along the extension direction of the removal groove.

[0041] In this embodiment, the oscillator is a rotary cylinder, and the oscillating shaft is fixed on the output disk of the rotary cylinder. In the initial position, the oscillating shaft is located in the horizontal direction parallel to the removal groove, and the oscillating shaft is located on one side of the removal groove. The positioning piece at the end of the oscillating shaft is opposite to the inserting slot of the rotating dial wheel. When the first pushing device drives the lock sleeve and the rotating dial wheel to move toward the oscillating shaft, the positioning piece is inserted into the lock cavity of the lock sleeve and the inserting slot of the rotating dial wheel in turn. At this time, the lock sleeve and the rotating dial wheel are integrally limited on the oscillating shaft. Driven by the oscillator, they are rotated and swung along the horizontal position to a vertical position of 90° for subsequent removal.

[0042] In this embodiment, the second biaxial removal device includes a second transverse movement cylinder, a second lifting cylinder and a second clamping claw cylinder. The second lifting cylinder and the second transverse movement cylinder are both linear cylinders. The second clamping claw cylinder is a clamping claw cylinder with a pair of second clamping claws. The sides of the two second clamping claws that are close to each other are recessed inward to form a slot. The opening position of the slot forms four contact inclined surfaces to achieve contact with the outer circular arc side wall of the lock sleeve body. When the lock sleeve is inserted, the circumferential side wall of the lock sleeve body is clamped between the four contact inclined surfaces, and the protrusion of the lock sleeve extends out along the gap between the second clamping claws and is limited and fixed by the side wall of the second clamping claw, so that the lock sleeve and the rotating dial wheel maintain a vertical and stable posture on the second clamping claw cylinder. At this time, the lock cavity of the lock sleeve is distributed along the vertical direction. The second gripper cylinder is fixed on the output shaft of the second lifting cylinder in a vertical posture, the second lifting cylinder is fixed on the output shaft of the second transverse cylinder in a vertical posture, and the second transverse cylinder is fixed on the corresponding bracket in a horizontal posture. When the second transverse cylinder is extended and retracted, the second lifting cylinder and the second gripper cylinder reciprocate above the tooling and the vertical swing position of the swing shaft. When the second lifting cylinder is extended and retracted, the second gripper cylinder moves to the vertical swing position of the swing shaft or moves to the lock core and central rotor position of the tooling, so that when the lock sleeve and the rotating dial wheel are driven to rotate by the swing shaft and the oscillator When it turns to the vertical position, the second clamping cylinder opens and clamps the outer side walls of the lock sleeve and the rotating dial wheel, and then, driven by the second transverse cylinder and the second lifting cylinder, the lock sleeve and the rotating dial wheel are moved to the top of the tooling and inserted vertically downward along the direction of the lock core and the center rotor, so that the lock core and the center rotor can smoothly penetrate into the lock sleeve along the lock cavity on one side. At this time, the rotor insert of the center rotor just penetrates into the insert slot of the rotating dial wheel, and the protrusion of the lock sleeve just penetrates along the limiting area between the two limiting shafts, and is stably limited to the positive fixed position of the tooling, completing the assembly of the lock sleeve and the rotating dial wheel.

[0043] In addition, combined Fig. 9The locking sleeve is then clamped by the corresponding second finger cylinder, and the two third clamping claws of the second finger cylinder have a pair of clamping pieces extending vertically downward, and the two clamping pieces protrude in a direction away from each other to form a columnar clamping block adapted to the lock cavity, so that the two clamping pieces penetrate along the notch groove of the lock sleeve, and when they are opened, the two clamping blocks penetrate into the lock cavities on both sides respectively, and the lock sleeve is raised at this time, so that the lock sleeve can be automatically rotated along the arc surface of the clamping block to a vertical posture with the protruding part facing downward under the deadweight of the lock sleeve, so as to smoothly move the lock sleeve to the removal jig, so that the protruding part can be smoothly inserted into the first limiting groove when the lock sleeve descends.

[0044] In addition, in order to realize the removal of the lock sleeve and the rotating dial wheel, the rotating dial wheel loading device and the lock sleeve loading device are integrated into a fourth dual-axis moving device, that is, through two mutually cooperating horizontal cylinders and vertical cylinders, a linkage plate is driven to move in the horizontal and vertical directions, and the finger cylinders used to clamp the lock sleeve and the rotating dial wheel are synchronously fixed on the linkage plate, and the distance between the two is consistent, and the distance between the rotating dial wheel loading position and the removal fixture and the distance between the lock sleeve loading position and the removal fixture are consistent with the distance between the two finger cylinders on the linkage plate, thereby realizing the alternating grasping and feeding of the lock sleeve and the rotating dial wheel.

[0045] In addition, the loading of the locking sleeve and the rotating dial wheel can also be achieved by grabbing the material tray. A material groove that engages with the locking sleeve or the rotating dial wheel is designed in the material tray, so that the locking sleeve or the rotating dial wheel is arranged in the material tray with the protruding part or the engaging part facing downward. Then, it is grabbed by a robot and placed in the transfer groove and the first limit groove of the transfer fixture, which can also complete the convenient loading of the locking sleeve and the rotating dial wheel.

[0046] In this embodiment, the first finger cylinder for grasping the rotating dial has two jaws provided with grasping grooves (not shown in the figure) adapted to the arc-shaped outer wall of the rotating dial, so as to facilitate stable grasping of the rotating dial.

[0047] Through the above process, the lock sleeve and the rotating dial are assembled on the lock core and the central rotor on the tooling, and then the tooling is transported by the conveying device to the position of the first retaining spring assembly mechanism to assemble the retaining spring.

[0048] like Fig.11 As shown, the first clamp spring assembly mechanism is used to insert the clamp spring into the buckle ring groove on the notch groove of the lock core and press it tightly to limit the axial position of the lock core; Specifically, in the present embodiment, the first retaining spring assembly mechanism and the second retaining spring assembly mechanism both include a retaining spring upper material position, a third lifting device, a retaining spring clamp, a double-stroke linear motion device, a compression spring device and a second pushing device. The third lifting device is used to lift the retaining springs one by one from the retaining spring upper material position. The retaining spring clamp has a clamping structure that can fix the retaining spring from the side so that the retaining spring opening is facing away from the retaining spring clamp. The double-stroke linear motion device is used to drive the retaining spring clamp to reciprocate between the initial position, the retaining spring upper material position and the retaining spring upper material position 51 on the tooling. The compression spring device has a pair of rivet claws for riveting the retaining spring. The second pushing device is used to push the compression spring device to the retaining spring upper material position 51.

[0049] In this embodiment, the retaining spring is loaded through a vibration plate in cooperation with a straight vibration track. The end of the conveying direction of the straight vibration track is the retaining spring loading position. The third lifting device is a linear cylinder, which is vertically arranged below the end of the conveying direction of the straight vibration track, and a cylindrical sleeve is provided at the end of its output shaft. The top of the sleeve forms a sleeve groove whose shape is adapted to the opening area on the inner side of the retaining spring, and its initial position is set below the straight vibration track. When the retaining spring is conveyed to the retaining spring loading position, the third lifting device rises, and the opening area on the inner side of the retaining spring penetrates into the sleeve and rises to a high position together with the sleeve, which is convenient for subsequent removal.

[0050] In order to achieve the removal of the retaining spring, the retaining spring clamp is designed as a long plate, including a base plate and a cover plate covering the upper end of the base plate. The front ends of the base plate and the cover plate are both recessed inward to form an arc-shaped opening groove. The arc-shaped opening groove is designed with a suction groove that is adapted to the shape of the retaining spring and can just accommodate the edge of the retaining spring. The suction groove and the retaining spring are fixed by magnetic attraction, vacuum adsorption or elastic compression to prevent the retaining spring from falling during the movement process. The magnetic attraction method is adopted in this embodiment. Therefore, when the retaining spring clamp moves to one side of the sleeve shaft, the edge of the retaining spring on the sleeve shaft is just stuck in the suction groove, and the retaining spring is limited in the suction groove under the action of magnetic attraction. Subsequently, the third lifting device descends, driving the sleeve shaft downward to leave the opening area of ​​the retaining spring and return to the initial position below the straight vibration track. After that, the retaining spring clamp can drive the retaining spring to move to one side of the tooling to carry out the assembly process of the retaining spring.

[0051] In order to realize the removal and movement of the retaining spring, in this embodiment, the double-stroke linear moving device includes two mutually cooperating first and second telescopic cylinders, the telescopic directions of the second telescopic cylinder and the first telescopic cylinder are parallel to each other, and the second telescopic cylinder is fixed on the output shaft of the first telescopic cylinder, and the retaining spring clamp is fixed on the output shaft of the second telescopic cylinder. Therefore, through the extension and retraction of the first and second telescopic cylinders, the retaining spring clamp can obtain two-stage linear strokes, so that it can move back and forth between the initial position, the material position of the first extended retaining spring and the tooling position of the second extended retaining spring, so as to realize the material taking and removal of the retaining spring. When the retaining spring clamp is extended in two stages under the drive of the double-stroke linear moving device, the opening area of ​​the retaining spring is just inserted into the notch groove of the lock sleeve on the tooling, and is inserted into the buckle ring groove at the upper end of the lock core. At this time, the retaining spring is still in an unrivet state and cannot limit the lock core.

[0052] In order to realize the riveting of the retaining spring, a compression spring device and a second pushing device are arranged on the other side of the tooling away from the retaining spring clamp. The second pushing device is a linear cylinder, and its telescopic direction is close to or away from the jig. The compression spring device is a clamp-type finger cylinder, and it has a pair of rivet claws. The two rivet claws protrude on one side close to each other to form an extension piece, and the end of the extension piece forms an arc-shaped pressure groove adapted to the arc surface of the notch groove. The finger cylinder is fixed on the output shaft of the second pushing device. When the second pushing device is extended, the extension pieces on the two clamping claws are located on both sides of the notch groove. When the two clamping claws are closed, their arc-shaped pressure groove just contacts the edge of the retaining spring. Continuing to close inward will deform the retaining spring and rivet it into the buckle ring groove of the lock core.

[0053] In this embodiment, in order to cooperate with the compression spring device, an auxiliary fixing device is also provided on the retaining spring clamp. The auxiliary fixing device has a linearly retractable auxiliary pressure block. The auxiliary pressure block is slidably arranged on one side of the clamping structure along the sliding direction of the retaining spring clamp, and is used to support the retaining spring in an extended state to cooperate with the rivet claw to rivet the retaining spring.

[0054] Specifically, the auxiliary pressure block is fixed on the output shaft of an auxiliary cylinder, and the auxiliary pressure block penetrates into one side of the suction groove. When the auxiliary cylinder extends, it drives the auxiliary pressure block to protrude slightly from the suction groove, thereby supporting the retaining spring, and cooperating with the pressure spring device to achieve stable riveting of the retaining spring, so that it can be smoothly fixed in the buckle ring groove of the lock core, thereby realizing axial limitation of the lock core on the lock sleeve. At this time, the lock sleeve can be moved to lift the installed parts as a whole.

[0055] like Fig.12 As shown, the finger turner feeding mechanism is used to grab the finger turner to the reverse fixed position so that the knob of the finger turner is limited in the first limit groove and the inner cavity opening of the finger turner faces upward; In this embodiment, the finger turner is manually placed on the loading conveyor belt, and is linearly transmitted to the finger turner loading position with the knob contacting the belt surface of the loading conveyor belt and the inner cavity facing upward. The finger turner loading mechanism includes a finger turner loading position, a third biaxial removal device and a second rotating device. The third biaxial removal device is used to move the finger turner at the finger turner loading position to the upper end of the first limit slot of the corresponding position tooling and insert the knob of the finger turner into the first limit slot. The second rotating device is used to rotate the finger turner to adjust the knob posture so that the knob can be smoothly inserted into the first limit slot.

[0056] The third double-axis moving device includes a third transverse moving cylinder and a third lifting cylinder. The third transverse moving cylinder is horizontally placed through corresponding brackets, and the end of its output shaft is fixed to the third lifting cylinder. The third lifting cylinder is fixed in a vertical posture, and its output shaft is telescoped downward. The second rotating device is a rotating cylinder, and is fixed to the end of the output shaft of the third lifting cylinder. A third finger cylinder is arranged on the output disk of the second rotating device. The third finger cylinder has a pair of fourth clamping claws. A moving piece is clamped and fixed between the two fourth clamping claws. The lower end of the moving piece has a moving structure that can be engaged with the inner cavity opening. The moving structure is on the third double-axis moving device. Driven by the taking device, it moves back and forth between the finger turner loading position and the tooling. When the finger turner moves along the loading conveyor belt to the finger turner loading position, the removing member descends to the opening position of the inner cavity of the finger turner, and the removing structure of the removing member penetrates into the inner cavity and is connected and fixed to the finger turner. Then, the removing member is driven by the third dual-axis removing device to move to the tooling, so that the finger turner is facing the first limit groove on the reverse fixed position, and the posture of the finger turner is adjusted by the second rotating device so that its knob is opposite to the direction of the first limit groove, and finally the knob is placed in the first limit groove, so that the finger turner completes the loading process on the tooling.

[0057] like Fig.13 As shown, the spring feeding mechanism is used to vertically place the spring into the inner cavity along the inner cavity opening at the end of the thumb turner; In this embodiment, the spring feeding mechanism includes a spring feeding position, a spring clamp, a third pushing device and a third swinging device. The spring clamp includes pressure claws on both sides and a positioning shaft arranged in the middle of the pressure claws. The positioning shaft is used to insert a single spring of the spring feeding position. The pressure claw is used to clamp the spring on the positioning shaft. The third swinging device is used to swing the positioning shaft along a circular path to a position opposite to the inner cavity opening of the finger turner. The third pushing device is used to telescopically move the spring clamp along a straight line so that the positioning shaft can approach the spring feeding position and the inner cavity opening.

[0058] The spring is stably loaded by the cooperation of the vibration plate and the direct vibration track, and a spring loading position is formed at the end of the direct vibration track. The spring clamp is a clamp-type finger cylinder with a pair of pressure claws, and a positioning shaft parallel to the direct vibration track is arranged between the pressure claws. After the spring is transmitted to the end of the direct vibration track, it is pushed outward by the subsequent spring to penetrate into the positioning shaft. At this time, the spring can be clamped and fixed by just closing the pressure claws.

[0059] In this embodiment, the third swing device is a rotary cylinder, and a third telescopic cylinder (i.e., a third pushing device) is fixed on the output disk of the rotary cylinder. The spring clamp is fixed at the end of the output shaft of the third telescopic cylinder, and the telescopic direction of the third telescopic cylinder is along the axial direction of the output disk. In the initial state, the spring clamp is in a horizontal state in which the positioning axis is parallel to the straight vibration track. After the third swing device drives the spring clamp to swing, it is vertically directed to the top of the tooling, and at this time, the positioning axis is opposite to the inner cavity opening of the finger turner on the tooling. After the third telescopic cylinder is extended, it drives the spring clamp and the spring to move downward together until the positioning axis contacts the inner cavity opening of the finger turner, and then the pressure claw is released, and the spring slides along the positioning axis into the inner cavity of the finger turner under the action of its own weight. Finally, the third telescopic cylinder retracts, and the third swing device drives the spring clamp to return to its original position, completing the spring feeding process.

[0060] Subsequently, the tooling drives the lock core, lock case, center rotor, rotating dial, retaining spring at the forward fixed position and the thumb turner and spring at the reverse fixed position, and they are transferred to the position of the flipping mechanism by the transmission device.

[0061] like Fig.14 As shown, the flipping mechanism is used to move the lock sleeve, the lock core rotating dial wheel and the central rotor which have been limited in the positive fixed position out of the limiting plate as a whole, and after vertical flipping, the other lock cavity opening of the lock sleeve is aligned with the inner cavity opening of the thumb turner in the reverse fixed position to realize the assembly of the thumb turner; Specifically, the flipping mechanism includes a fourth swinging device, a second clamping device and a second lifting device. The second clamping device has a pair of fifth clamping jaws for clamping the outer wall of the locking sleeve. The second lifting device is used to drive the second clamping device to lift and lower vertically. The fourth swinging device is used to drive the second clamping device to swing along a circular path to realize the flipping of the locking sleeve in the vertical direction, thereby transferring it from the forward fixed position to the reverse fixed position.

[0062] In this embodiment, the fourth swing device is a rotary cylinder, and the second clamping device is fixed on its output disk. The second clamping device is a finger cylinder. The second clamping device is eccentrically arranged with the center of the rotary cylinder output disk. Driven by the rotary cylinder, it is deviated 180° in the vertical direction, so that the object clamped by the second clamping device can just achieve a 180° vertical flip. The purpose of this structure is to clamp the lock core, center rotor, rotating dial and retaining spring that are integrally fixed in the lower lock cavity of the lock sleeve through the second clamping jaw, and flip them vertically with the lock sleeve to the position of the lock cavity above the lock sleeve, so that the lower lock cavity of the lock sleeve is facing downward at this time, and can continue to accommodate the finger turner and spring to penetrate.

[0063] In this process, when the fourth swing device drives the second clamping jaw device to swing, its two swinging points are respectively located at the lock sleeve position on the positive fixed position and the thumb turner position on the reverse fixed position.

[0064] In order to further achieve the giving way during the flipping process of the lock sleeve and avoid the tooling from affecting the flipping process of the lock sleeve, the second lifting device is a linear rodless cylinder, and is installed and fixed in a vertical posture through a corresponding bracket, with its output shaft facing the vertical upward direction. The fourth swing device is fixed to the output shaft of the second lifting device, so that the fourth swing device and the second clamping claw are driven by the second lifting device to achieve synchronous lifting and lowering. After the second clamping claw clamps the outer wall of the lock sleeve, the second lifting device drives it to rise so that the lock core is out of the range of the limit plate. Then the fourth swing device drives the lock sleeve to flip 180° along the circular path, so that the lock cavity that originally opened upward becomes just vertically downwardly opened and facing the first limit groove on the reverse fixed position. At this time, the lock cavity and the inner cavity opening of the upper end of the finger turner are also positively opposite, and the second lifting device retracts, so that the lock sleeve moves downward as a whole, and the upper end of the finger turner penetrates into the lock cavity at the lower end of the lock sleeve to complete the preliminary assembly of the finger turner. Finally, the second clamping claw device releases the lock sleeve, and rises again to return to its original position under the action of the fourth swing device and the second lifting device.

[0065] In the above process, in order to enhance the clamping effect on the outer wall of the lock sleeve, the second clamping jaw device has a pair of fifth clamping jaws, and an arc-shaped clamping groove adapted to the main body of the lock sleeve is opened on the side where the two fifth clamping jaws are close to each other, and the two sides of the arc-shaped clamping groove and the side walls of the clamping jaws form a flat surface. Therefore, when the clamping jaws clamp the lock sleeve, the main body of the lock sleeve is clamped and limited by the clamping grooves on both sides, and the protruding part of the lock sleeve is also stably limited under the restriction of the surfaces on both sides, so that the lock sleeve maintains a stable orientation during the entire flipping and swinging process, which is convenient for plugging and matching with the thumb turner.

[0066] After the above process is completed, the thumb turner, spring, rotating dial, center rotor, lock core and lock sleeve are integrated on the tooling in the reverse fixed position, wherein the thumb turner is still not limited. Under the transmission of the transmission device, the tooling continues to be transmitted to the second retaining spring assembly mechanism.

[0067] Combination Figure 4 and Fig.11 The second retaining spring assembly mechanism is used to insert the retaining spring into the snap ring groove on the notch groove of the thumb turner and press it to limit the thumb turner axially. In this embodiment, the structure of the second retaining spring assembly mechanism is exactly the same as that of the first retaining spring assembly mechanism. The difference lies in that the assembly heights of the retaining springs are slightly different. Therefore, by adjusting the height of the second retaining spring assembly mechanism, the second retaining spring can be smoothly assembled, so that the thumb turner is axially limited on the lock sleeve, completing the overall assembly process of the lock core.

[0068] It also includes a unloading mechanism, which includes a fourth double-axis device, a clamping device and a lock core unloading position. The clamping device is used to clamp the assembled outer wall of the lock sleeve. The fourth double-axis device is used to drive the clamping device to move on the horizontal axis and the vertical axis so that the clamping device moves between the tooling and the lock core unloading position at the corresponding position. The lock core unloading position is connected to the unloading conveyor belt or the finished product container.

[0069] Specifically, Fig.15 The figure shows the unloading mechanism of the lock core, which uses a fourth dual-axis device that is the same as the aforementioned dual-axis removal device. The clamping device is a clamping finger cylinder, and its clamping claws have clamping grooves that are adapted to the shape of the lock sleeve. In conjunction with the corresponding unloading conveyor belt, the assembled lock core is clamped and removed to the unloading conveyor belt for transmission, and the tooling is cyclically transmitted to the initial position for the next round of lock core assembly.

[0070] In addition, the unloading conveyor belt can be replaced with a finished product container, such as an unloading tray, so as to realize the unified collection and unloading of the assembled finished lock cylinders.

[0071] like Fig.16As shown, in this embodiment, the conveying device cyclically conveys along a U-shaped rotating path on a vertical plane, and includes an upper conveying path and a lower conveying path with opposite conveying directions. An upper pushing cylinder is arranged at the initial conveying position of the upper conveying path, which is used to push the tooling one by one onto the upper conveying path. A lower pushing cylinder is arranged at the initial conveying position of the lower conveying path, which is used to push the tooling one by one onto the lower conveying path. Elevator cylinders are arranged at the initial positions of the upper conveying path and the lower conveying path. The elevator cylinders include a linear cylinder and an elevator seat. The elevator seat includes a cylinder that can carry the tooling. The lifting elevator slot, when the tooling moves gradually along the lower conveying path to the initial position of the upper conveying path at its end, enters the elevator slot on that side, and the elevator cylinder drives the elevator slot to rise, so that it reaches the initial position of the upper conveying path, and then enters the upper conveying path under the action of the upper push cylinder; similarly, the tooling conveyed to the end of the upper conveying path enters the elevator slot on that side, and the elevator cylinder drives the elevator slot to descend, so that it reaches the initial position of the lower conveying path, and then enters the lower conveying path under the action of the lower push cylinder, thereby realizing the cyclic conveyance of the tooling.

[0072] In addition, on the upper conveying path, the cyclic drive of the tooling pushes the tooling into the upper conveying path one by one through the upper push cylinder, and the next tooling continues to move forward under the push of the upper tooling, that is, the upper push cylinder is used as the power source for continuous cyclic pushing.

[0073] In order to reduce the amount of tooling used, the lower conveying path is driven by the lower conveyor belt. Therefore, a single tooling can be conveyed on the lower conveyor belt. It is only necessary to consider the time interval so that the upper conveyor belt is always continuously covered with tooling to realize the cyclic conveying process of tooling.

[0074] In particular, all the dual-axis removal devices in this embodiment, in addition to the above-mentioned linear cylinder drive method, can also achieve dual-axis movement on the horizontal and vertical axes through the cooperation of the motor screw structure, and the cooperation of the motor screw structure and the cylinder, without limitation here.

[0075] The beneficial effects of the present invention are as follows: The present invention uses a tooling with a forward fixing position and a reverse fixing position to respectively fix the lock core and the thumb turner at both ends of the lock core, assembles the center rotor and the spring based on the lock core and the thumb turner, and then inserts the lock sleeve and the rotating dial into the forward fixing position as a whole to complete the assembly with the lock core and the center rotor, and finally flips the lock sleeve as a whole to the reverse fixing position to complete the assembly of the lock sleeve and the thumb turner. Through the above assembly process, the assembly process of the single-opening lock core can be conveniently and efficiently realized, thereby solving the assembly problem of the single-opening lock core.

[0076] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
