[0001] This application relates to the field of lock cylinder manufacturing and processing technology, and in particular to an automatic assembly mechanism for the upper and lower lock cylinders. Background Technology
[0002] Locks are widely used in people's daily lives. As people's requirements for the security and confidentiality of locks continue to increase, enterprises have also put forward higher requirements for the manufacturing and assembly of mortise lock cylinders. As the main part that controls the opening of the lock, the lock cylinder is the heart of the lock and is the core part that is matched with the key and can rotate to drive the bolt.
[0003] Existing lock cylinders such as Figure 1 As shown, a typical lock cylinder includes a lock case a, a lock cylinder b, a turntable c, a center wheel d, and a retaining ring e. During the manufacturing process of the lock cylinder, the center wheel d and the two lock cylinders b are first inserted from the outside of the lock case a, and the turntable c is placed in the middle notch of the lock case a, so that the two lock cylinders b are inserted into the turntable c. The center wheel d passes through the turntable c and can drive the turntable c to rotate. Then, retaining rings e are installed at both ends of the turntable c to restrict the axial movement of the lock cylinders b.

It also includes a lock cylinder feeding assembly, a flipping assembly mounted on the base for flipping the lock cylinder, a transfer assembly for transferring the lock cylinder on the flipping assembly, a lower lock cylinder assembly assembly assembly for assembling the lock cylinder on the transfer assembly assembly from below onto the lock cylinder in the lock cylinder assembly fixture, and a lock cylinder feeding assembly for automatically feeding the lock cylinder on the lock cylinder feeding assembly onto the flipping assembly or onto the lock cylinder in the lock cylinder assembly fixture from above.
[0008] Preferably, the cylinder feeding assembly includes a multi-axis robot mounted on a base and a cylinder picking fixture mounted on the multi-axis robot for picking up cylinders from the cylinder feeding assembly. The multi-axis robot drives the cylinder picking fixture to reciprocate between the cylinder feeding assembly, the flipping assembly, and the cylinder assembly fixture.
[0009] Preferably, the cylinder feeding assembly includes two feeding units. Each feeding unit includes a multi-axis robot mounted on a base and a cylinder picking fixture mounted on the multi-axis robot for picking up the cylinder from the cylinder feeding assembly. One feeding unit reciprocates between the cylinder feeding assembly and the flipping assembly, while the other feeding unit reciprocates between the cylinder feeding assembly and the cylinder assembly fixture.

[0012] Preferably, the lower lock cylinder assembly includes an assembly cylinder unit mounted on the base, the assembly cylinder unit driving the positioning and feeding rod to reciprocate in the direction of the lock cylinder assembly fixture.
[0013] Preferably, multiple positioning and feeding rods are provided, and the multiple positioning and feeding rods are installed in a ring on the rotating disk.
[0014] Preferably, the cylinder feeding assembly includes a material tray with multiple cylinder placement slots arranged in an array on the material tray for placing cylinders, and the multi-cylinder feeding assembly reciprocates between the material tray, the flipping assembly and the cylinder assembly fixture.
[0015] Preferably, the locking cylinder feeding assembly further includes a conveyor table for conveying material trays, and multiple material trays are arranged sequentially on the conveyor table.
[0016] Preferably, a finger cylinder is installed on the base, the finger cylinder is located above the lock cylinder assembly fixture, the finger cylinder includes two symmetrically arranged jaws, and when the two jaws are closed, a guide hole is formed, the guide hole is funnel-shaped, and the lock cylinder feeding assembly reciprocates between the lock cylinder feeding assembly and the finger cylinder.
[0017] In summary, this application includes at least one of the following beneficial technical effects:
[0018] The lock cylinder feeding assembly reciprocates between the lock cylinder feeding assembly, the flipping assembly, and the lock cylinder assembly fixture, achieving continuous feeding of the upper and lower lock cylinders. On one hand, the flipping assembly rotates the lock cylinder 180°, and then the transfer assembly positions and transfers the rotated lock cylinder. The lower lock cylinder assembly assembly then assembles the lock cylinder from below onto the lock cylinder in the lock cylinder assembly fixture, completing the automatic assembly process of the lower lock cylinder. On the other hand, the lock cylinder feeding assembly reciprocates between the lock cylinder feeding assembly and the lock cylinder assembly fixture, feeding the lock cylinder from above onto the lock cylinder in the lock cylinder assembly fixture, completing the automatic assembly process of the upper lock cylinder. The reciprocating action of the lock cylinder feeding assembly between the lock cylinder feeding assembly, the flipping assembly, and the lock cylinder assembly fixture achieves automatic assembly of the upper and lower lock cylinders onto the lock cylinder in the lock cylinder assembly fixture, resulting in a high degree of automation, high assembly efficiency, and good assembly quality.
[0019] By setting the cylinder feeding assembly into two feeding units, each feeding unit includes a multi-axis robot mounted on a base and a cylinder picking fixture mounted on the multi-axis robot for picking up cylinders from the cylinder feeding assembly. One feeding unit reciprocates between the material tray and the flipping assembly to automatically feed the cylinders onto the clamping cylinder. The other feeding unit reciprocates between the material tray and the cylinder assembly fixture to assemble the cylinders from above into the cylinders on the cylinder assembly fixture, thereby improving the installation efficiency of cylinder assembly.
[0020] By setting the pushing assembly component and the lifting cylinder unit as multiple assembly cylinder units mounted on the rotating plate, each assembly cylinder unit corresponds to and is fixedly connected to the positioning and feeding rod; multiple individual assembly cylinder units drive the positioning and feeding rod to move towards the lock cylinder assembly fixture or the flipping unit, so as to realize the purpose of feeding the lock cylinder on the flipping component to the feeding positioning rod or assembling the lock cylinder on the feeding positioning rod to the lock cylinder inside the lock cylinder assembly fixture;
[0021] By setting up a conveyor table to convey multiple material pallets in sequence, the lock cylinder feeding component continuously picks up lock cylinders from the lock cylinder feeding component in sequence, thereby achieving the purpose of continuous lock cylinder feeding.
[0022] The positioning block is driven by the positioning cylinder to reciprocate towards the rotating disk. During the assembly of the lock cylinder, the driving cylinder drives the positioning block to insert into the positioning groove to achieve the positioning of the rotating disk, so that one of the positioning feeding rods is located directly below the clamping cylinder, and one of the positioning feeding rods is located in front of the assembly cylinder unit, which improves the accuracy of the transfer component for feeding the lock cylinder.
[0023] By installing finger cylinders on the base, a funnel-shaped guide hole is formed when the two grippers of the finger cylinders are closed. During the assembly of the lock cylinder, the guide hole is located directly above the lock cylinder inside the lock cylinder assembly fixture. The lock cylinder feeding component reciprocates between the material tray and the finger cylinder, so that the lock cylinder is introduced from the guide hole and then fed from above onto the lock cylinder inside the lock cylinder assembly fixture, thereby improving the accuracy of the lock cylinder feeding component in feeding and assembling the lock cylinder onto the lock cylinder inside the lock cylinder assembly fixture.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.
[0034] This application discloses an automatic assembly mechanism for the upper and lower lock cylinders. Example 1
[0035] Reference Figure 2 , Figure 3 The automatic assembly mechanism for the upper and lower lock cylinders includes a base 1, a lock cylinder feeding assembly 2, a rotating disk 3 rotatably mounted on the base 1, multiple lock cylinder assembly fixtures 4 mounted on the rotating disk 3 for fixing the lock cylinder and assembling the lock cylinder onto the lock cylinder, a flipping assembly 5 mounted on the base 1 for flipping the lock cylinder, a transfer assembly 6 for transferring the lock cylinder on the flipping assembly 5, a lower lock cylinder assembly assembly 7 for assembling the lock cylinder on the transfer assembly 6 from below onto the lock cylinder inside the lock cylinder assembly fixture 4, and a lock cylinder feeding assembly 8 for automatically feeding the lock cylinder on the lock cylinder feeding assembly 2 onto the flipping assembly 5 or feeding it from above onto the lock cylinder inside the lock cylinder assembly fixture 4.
[0036] Reference Figures 2 to 6 The lock cylinder feeding assembly 2 includes a material tray 21 and a conveyor table 22 for conveying the material tray 21. Multiple material trays 21 are arranged sequentially on the conveyor table 22. Multiple lock cylinder placement slots 211 for placing lock cylinders are arrayed on the material tray 21. Lock cylinders to be assembled are placed vertically in the lock cylinder placement slots 211 in the same direction. The material tray 21 is conveyed by the conveyor table 22, and the lock cylinder feeding assembly 8 continuously picks up lock cylinders from the lock cylinder feeding assembly 2, so as to achieve the purpose of continuous lock cylinder feeding.
[0037] The cylinder loading assembly 8 includes a multi-axis robot 81 mounted on the base 1 and a cylinder picking gripper 82 mounted on the multi-axis robot 81 for picking up cylinders from the cylinder feeding assembly 2. The multi-axis robot 81 is a robotic arm that moves in multiple axes in the X, Y, and Z planes. The cylinder picking gripper 82 is a finger gripper cylinder. The multi-axis robot 81 drives the cylinder picking gripper 82 to reciprocate between the material tray 21, the flipping assembly 5, and the cylinder assembly fixture 4, automatically loading the cylinders from the cylinder feeding assembly 2 onto the flipping assembly 5 or loading them from above onto the cylinders inside the cylinder assembly fixture 4.
[0038] The flipping assembly 5 includes a rotary motor 51 mounted on the base 1 and a clamping cylinder 52 mounted on the output shaft of the rotary motor 51 for clamping the lock cylinder. The rotary motor 51 drives the clamping cylinder 52 to rotate 180°. This facilitates the flipping of the lock cylinder and its interaction with the lower lock cylinder assembly assembly 7 via the transfer assembly 6, so that the lock cylinder can be assembled onto the lock cylinder from below the lock cylinder assembly fixture 4.
[0039] The transfer assembly 6 includes a rotating disk 61 rotatably mounted on the base 1, a power source 62 for driving the rotating disk 61 to rotate, a plurality of positioning and feeding rods 63 slidably mounted on the rotating disk 61, and a lifting cylinder unit 64 mounted on the base 1. The power source 62 can be a motor assembly or a gear and rack mechanism. A plurality of positioning and feeding rods 63 are provided, and the plurality of positioning and feeding rods 63 are arranged in a ring on the rotating disk 61.
[0040] The lower lock cylinder assembly assembly 7 includes an assembly cylinder unit mounted on the base 1. Each time, the assembly cylinder unit drives one of the positioning and feeding rods 63 to move in the direction of the lock cylinder assembly fixture 4, and assembles the lock cylinder on the positioning and feeding rod 63 from below onto the lock cylinder inside the lock cylinder assembly fixture 4. The flipping assembly 5 is located above the positioning and feeding rod 63, and when feeding, the lifting cylinder unit 64 drives the positioning and feeding rod 63 to move in the direction of the fixture cylinder, and transfers the lock cylinder on the fixture cylinder to the positioning and feeding rod 63.
[0041] Reference Figure 5 , Figure 6 To improve the accuracy of the transfer assembly for loading the lock cylinder, a positioning cylinder 65 is installed on the base 1. The positioning cylinder 65 is connected to a positioning block 66. Positioning slots 611, corresponding one-to-one with the number of positioning loading rods 63, are opened on the circumference of the rotating disk 61. The positioning cylinder 65 drives the positioning block 66 to reciprocate in the direction of the rotating disk 61. During the assembly of the lock cylinder, the driving cylinder drives the positioning block 66 to insert into one of the positioning slots 611 to position the rotating disk 61, so that one of the positioning loading rods 63 is located directly below the clamping cylinder 52, and one of the positioning loading rods 63 is located in front of the assembly cylinder unit.
[0042] Reference Figure 2 , Figure 3 , Figure 7 To improve the accuracy of the lock cylinder feeding assembly 8 feeding material from above onto the lock cylinder in the lock cylinder assembly fixture 4, a finger cylinder 83 is installed on the base 1. The finger cylinder 83 includes two symmetrically arranged grippers. When the two grippers are closed, a guide hole 831 is formed. The guide hole 831 is funnel-shaped. When assembling the lock cylinder, the lock cylinder feeding assembly 8 reciprocates between the material tray 21 and the finger cylinder 83. The guide hole 831 is located directly above the lock cylinder in the lock cylinder assembly fixture 4.
[0043] The implementation principle is as follows: During the assembly of the lock cylinder, the multi-axis robot 81 in the lock cylinder feeding assembly 8 drives the lock cylinder picking fixture 82 to reciprocate between the lock cylinder feeding assembly 2, the flipping assembly 5, and the lock cylinder assembly fixture 4, thereby achieving continuous feeding of the upper and lower lock cylinders. On one hand, after the lock cylinder is flipped 180° by the flipping assembly 5, the lifting cylinder unit 64 in the transfer assembly 6 drives the positioning feeding rod 63 located directly below the clamping cylinder 52 to move towards the clamping cylinder 52, thereby transferring the flipped lock cylinder to the positioning feeding rod 63. Then, the lower lock cylinder assembly assembly 7 drives the positioning feeding rod 63 to move in a directional direction towards the lock cylinder assembly fixture 4, and assembles the lock cylinder on the positioning feeding rod 63 from below into the lock cylinder assembly fixture. The automatic assembly process of the lower lock cylinder is completed on the inner lock cylinder of the 4-piece lock cylinder assembly fixture. After being positioned and rotated by the rotary disk 3, the lock cylinder feeding component 8 reciprocates between the lock cylinder feeding component 2 and the lock cylinder assembly fixture 4, so that the guide hole 831 on the finger cylinder 83 is located directly above the lock cylinder inside the lock cylinder assembly fixture 4. The lock cylinder feeding component 8 feeds the lock cylinder into the guide hole 831 and then feeds it from above onto the lock cylinder inside the lock cylinder assembly fixture 4, completing the automatic assembly process of the upper lock cylinder. By the reciprocating action of the lock cylinder feeding component 8 between the lock cylinder feeding component 2, the flipping component 5, and the lock cylinder assembly fixture 4, the upper and lower lock cylinders are automatically assembled onto the lock cylinder inside the lock cylinder assembly fixture 4, which has the effect of improving the degree of automation, the assembly efficiency, and the assembly quality. Example 2
[0044] Reference Figure 2 , Figure 3 , Figure 8 An automatic assembly mechanism for upper and lower lock cylinders is disclosed, differing from Embodiment 1 in that the lower lock cylinder assembly assembly 7 includes multiple assembly cylinder units mounted on a rotating disk 61. The lifting cylinder unit 64 is also an assembly cylinder unit, and each of the multiple assembly cylinder units corresponds to and is fixedly connected to the positioning and feeding rod 63. By driving the positioning and feeding rod 63 towards the lock cylinder assembly fixture 4 or the flipping unit through multiple individual assembly cylinder units, the mechanism aims to feed the lock cylinder from the flipping assembly 5 onto the feeding and positioning rod, or to assemble the lock cylinder from the feeding and positioning rod onto the lock cylinder within the lock cylinder assembly fixture 4. Example 3
[0045] Reference Figure 2 , Figure 3An automatic assembly mechanism for upper and lower lock cylinders is provided, which differs from Embodiment 1 in that the lock cylinder feeding assembly 8 includes two feeding units. Each feeding unit includes a multi-axis robot 81 mounted on the base 1 and a lock cylinder picking fixture 82 mounted on the multi-axis robot 81 for picking up the lock cylinders from the lock cylinder feeding assembly 2. One feeding unit reciprocates between the material tray 21 and the flipping assembly 5 to automatically feed the lock cylinders onto the clamping cylinder 52. The other feeding unit reciprocates between the material tray 21 and the lock cylinder assembly fixture 4 to assemble the lock cylinders from above into the lock cylinders on the lock cylinder assembly fixture 4.
