Description

TECHNICAL FIELD

[0001] The utility model relates to the field of blade lock core assembly, specifically relates to a component transfer structure of full automatic assembly machine. BACKGROUND

[0002] In the overall assembly of the blade lock core, the end cover as a key packaging component, its assembly quality directly affects the sealing and structural stability of the lock core. The end cover structure is more complex, in addition to the precise fit with the core body, the end cover fixed hole and the core body screw hole are completely aligned, and the key insertion port is integrated, and the end cover end needs to install the rotating shaft, the torsional spring and the baffle - the baffle is sleeved on the rotating shaft, and the key insertion port needs to be precisely closed under the action of the torsional spring, and the closing gap needs to be controlled within 0.05mm, otherwise the key insertion will be jammed or the sealing will be poor.

[0003] The existing equipment has more shortcomings in the end cover assembly link: the traditional transfer structure is difficult to consider the macro alignment of the end cover and the core body and the micro assembly precision of the peripheral components of the key insertion port, and the baffle is often deviated due to the installation inclination of the rotating shaft and the uneven stress of the torsional spring; the shaking caused by the sliding pair gap in the transfer process will cause the baffle to collide with the edge of the key insertion port, causing burrs or deformation and affecting the sealing performance; if the end cover edge is not properly forced by the clamping assembly, the key insertion port is easily deformed, and the small rotating shaft and torsional spring cannot be accurately grabbed, resulting in component falling or installation misalignment; the existing buffer device cannot control the pre-tightening force of the torsional spring during assembly, and the torsional spring is easily damaged due to excessive impact force, so that the baffle cannot be normally reset.

[0004] These problems make the assembly qualification rate of the end cover of the blade lock core only about 55%, which becomes the core bottleneck restricting the large-scale production of the blade lock core, so a special transfer structure that can adapt to the complex structure of the end cover and the precise assembly requirement is needed.

[0029] The component transfer structure of the full-automatic assembly machine provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0030] Embodiment 1

[0031] The embodiments of the present application provide a component transfer structure of a full-automatic assembly machine, which comprises a feeding assembly 1 and a clamp 2, and further comprises a mounting frame 3, a horizontal moving assembly 4, a vertical moving assembly 5 and a clamping assembly 6; the horizontal moving assembly 4 is installed on the mounting frame 3, the vertical moving assembly 5 is installed on the horizontal moving assembly 4, and the clamping assembly 6 is installed on the vertical moving assembly 5; the horizontal moving assembly 4 and the vertical moving assembly 5 cooperatively drive the clamping assembly 6 to move between the feeding assembly 1 and the clamp 2, and the clamping assembly 6 is used for clamping a component to be transferred.

[0032] As shown in Figures 1 to 6 , when the component transfer is needed, the horizontal moving assembly 4 can drive the vertical moving assembly 5 and the clamping assembly 6 to move along the horizontal direction on the mounting frame 3 to adjust the horizontal position of the clamping assembly 6; the vertical moving assembly 5 can drive the clamping assembly 6 to move along the vertical direction to realize the height adjustment; through the cooperative action of the horizontal moving assembly 4 and the vertical moving assembly 5, the clamping assembly 6 can be accurately moved to the feeding assembly 1, and after the clamping assembly 6 clamps the component to be transferred, the component is transferred to the clamp 2 through the cooperation of the horizontal moving assembly 4 and the vertical moving assembly 5, thereby completing the transfer process of the component.

[0033] Embodiment 2

[0034] The difference between the embodiment 1 and the embodiment 2 is that, in the embodiment 2, in addition to the structural features of the foregoing embodiment, the horizontal moving assembly 4 comprises a horizontal moving fixed plate 41, a connecting frame 42, a sliding pair 43 and an actuator 44, the horizontal moving fixed plate 41 is installed on the mounting frame 3 through the connecting frame 42, the vertical moving assembly 5 is slidingly installed on the horizontal moving fixed plate 41 through the sliding pair 43, and the horizontal movement is driven through the actuator 44.

[0035] In the embodiment of the present application, the horizontal moving assembly 4 further comprises a pair of buffer devices 45, which are respectively installed on the left and right ends of the horizontal moving fixed plate 41, and the contact ends of each buffer device 45 are all directed towards the vertical moving assembly 5.

[0036] As shown in Figures 2 to 4As shown, due to the aforementioned structure, the transverse fixed plate 41 is securely mounted on the mounting frame 3 via the connecting bracket 42, providing a stable foundation for horizontal movement. When the actuator 44 is activated, its driving force acts on the vertical moving component 5, causing the vertical moving component 5 to slide smoothly horizontally on the transverse fixed plate 41 via the sliding pair 43, thereby driving the vertical moving component 5 and the clamping component 6 mounted on the connecting plate 51 to move synchronously. When the connecting plate 51 moves to its limit position at both ends of the transverse fixed plate 41 under the drive of the actuator 44, the connecting plate 51 will contact the corresponding buffer device 45. The buffer device 45 can effectively buffer the impact force of the connecting plate 51, avoiding direct collision between the vertical moving component 5 and the end of the transverse fixed plate 41, thus ensuring the safety and stability of the horizontal movement process.

[0037] Example 3:

[0038] The difference from Embodiment 1 is that, in this embodiment, in addition to the structural features of the aforementioned embodiments, the vertical moving component 5 includes a connecting plate 51, a lifting plate 52, a second sliding joint 53, and a second actuator 54. The connecting plate 51 is movably mounted on the horizontal moving component 4 via the first sliding joint 43, the lifting plate 52 is movably mounted on the connecting plate 51 via the second sliding joint 53, and the lifting is driven by the second actuator 54.

[0039] In this embodiment of the application, the vertical moving component 5 further includes a pair of buffer devices 55, which are respectively installed at the upper and lower ends of the connecting plate 51, and the contact ends of each buffer device 55 face the lifting plate 52.

[0040] like Figures 2 to 5 As shown, due to the aforementioned structure, the connecting plate 51 moves synchronously with the horizontal moving component 4, providing support for vertical movement. When the actuator 54 operates, it drives the lifting plate 52 to move vertically on the connecting plate 51 via the sliding pair 53, thereby causing the clamping component 6 to adjust its height. When the lifting plate 52 moves to its limit position at both ends of the connecting plate 51 under the action of the actuator 54, the lifting plate 52 will contact the corresponding buffer device 55. The buffer device 55 can effectively absorb the impact force of the lifting plate 52, preventing the lifting plate 52 from colliding hard with the end of the connecting plate 51, ensuring the stability and safety of the vertical movement process.

[0041] The actuator 44 of the horizontal moving component 4 and the actuator 54 of the vertical moving component 5 are synchronized via PLC signals. The moving path of the clamping component 6 is positioned by a slide rail, and the displacement error in the horizontal and vertical directions is ≤0.1mm.

[0042] Example 4:

[0043] The difference between the embodiment and the embodiment 2 or 3 is that, in the embodiment, in addition to the structural features of the foregoing embodiments, the sliding pair one 43 and the sliding pair two 53 each comprises a sliding rail 541 and a sliding block 542, the sliding rail 541 is fixedly arranged on the horizontal movement fixed plate 41 or the connecting plate 51, and the sliding block 542 is fixedly arranged on the connecting plate 51 or the lifting plate 52 and is in sliding cooperation with the sliding rail 541.

[0044] As shown in Figures 4 to 5 , due to the adoption of the above structure, when the sliding pair one 43 works, the sliding block 542 fixedly arranged on the connecting plate 51 can slide along the sliding rail 541 fixedly arranged on the horizontal movement fixed plate 41 accurately, so that the movement of the connecting plate 51 in the horizontal direction is more stable and the guidance is more accurate; when the sliding pair two 53 works, the sliding block 542 fixedly arranged on the lifting plate 52 can smoothly slide along the sliding rail 541 fixedly arranged on the connecting plate 51, so as to ensure that the movement of the lifting plate 52 in the vertical direction has good straightness and stability, reduces the shaking in the movement process, and improves the precision of the component transfer.

[0045] Embodiment 5

[0046] The difference between the embodiment and the embodiment 2 or 3 is that, in the embodiment, in addition to the structural features of the foregoing embodiments, the actuator one 44 and the actuator two 54 are each a pneumatic cylinder, and the outer end of the piston of the pneumatic cylinder is connected with the connecting plate 51 or the lifting plate 52 through the adapter 7.

[0047] In the embodiment of the application, the adapter 7 comprises an adapter slot 71 and an adapter block 72, the adapter slot 71 is arranged on the side of the connecting plate 51 or the top of the lifting plate 52, and the adapter block 72 is fixedly arranged on the outer end of the piston and is inserted into the corresponding adapter slot 71, and the width of the opening end of the adapter slot 71 is smaller than the width of the inner end

[0048] As shown in Figures 2 to 3 , due to the adoption of the above structure, when the actuator one 44 is a pneumatic cylinder, the piston of the pneumatic cylinder is extended or retracted to drive the adapter block 72 to move, the adapter block 72 is inserted into the adapter slot 71 on the side of the connecting plate 51, and the width of the opening end of the adapter slot 71 is smaller than the width of the inner end, so as to prevent the adapter block 72 from falling off from the adapter slot 71, to ensure stable power transmission, thereby driving the connecting plate 51 to move along the sliding pair one 43; when the actuator two 54 is a pneumatic cylinder, the piston is extended or retracted to drive the adapter block 72 to cooperate with the adapter slot 71 on the top of the lifting plate 52, thereby driving the lifting plate 52 to move along the sliding pair two 53, and the same adapter structure ensures the reliability of the power transmission.

[0049] Embodiment 6

[0050] The difference between the embodiment and the embodiment 2 or 3 is that, in the embodiment, in addition to the structural features of the foregoing embodiments, the buffer device one 45 or the buffer device two 55 is a pneumatic cylinder with a stroke of 5 mm.

[0051] AsFigures 1 to 4 As shown, due to the above structure, when the buffer device 45 is a buffer cylinder, when the connecting plate 51 moves to the ends of the transverse fixed plate 41 to near its limit position, the connecting plate 51 will first contact the piston rod of the buffer cylinder. The gas inside the buffer cylinder is compressed, generating a buffering force, which gradually slows down the moving speed of the connecting plate 51 until the connecting plate 51 stops moving, thus avoiding a violent collision between the connecting plate 51 and the end of the transverse fixed plate 41. When the buffer device 55 is a buffer cylinder, when the lifting plate 52 moves to the ends of the connecting plate 51 to near its limit position, the piston rod of the buffer cylinder contacts the lifting plate 52. The buffering force generated by gas compression reduces the moving speed of the lifting plate 52, achieving a soft stop and protecting the lifting plate 52 and related components.

[0052] Example 7:

[0053] The difference from Embodiment 1 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the clamping component 6 is a pneumatic mechanical gripper.

[0054] like Figure 6 As shown, due to the above structure, when the clamping assembly 6 moves to the feeding assembly 1 to clamp the part, the pneumatic mechanical gripper is driven by the air source. The gripper (with a micro-clamping block fixed at its lower end to adapt to the gripping of micro parts) opens and aligns with the part. Then the gripper closes to firmly clamp the part. When the part needs to be placed at the fixture 2, the pneumatic mechanical gripper is controlled by the air source again. The gripper opens and releases the part, completing the clamping and releasing action of the part. Its pneumatic drive mode is responsive and has a stable clamping force, which can adapt to the transfer needs of parts of different specifications.
