Description

Technical Field

[0001] The utility model relates to the technical field of automatic assembly of non-standard locks, in particular to a U-shaped rivet sorter. Background Art

[0002] The lock structure is generally divided into five parts: handle, lock plate, lock body, lock core and accessories. Among them, the lock plate is an important carrier for fixing the handle, lock plate, lock body, lock core and accessories. It is composed of two symmetrical plates stacked and riveted with U-shaped rivets. Among them, U-shaped rivets are generally formed by bending and twisting steel bars. Although U-shaped rivets are inexpensive, they will have a certain degree of rebound after forming, which often makes it difficult to make them consistent in shape, which in turn causes the U-shaped rivets and the lock plate to not fit well.

[0003] Therefore, under the condition that the shape of the U-shaped rivets cannot be guaranteed to remain consistent, it is necessary to screen the U-shaped rivets, remove the U-shaped rivets with unqualified shapes, and retain the qualified U-shaped rivets to be assembled with the lock plate, thereby realizing mass production of locks. Utility Model Content

[0004] To this end, the utility model provides a U-shaped rivet sorter to solve the problem in the prior art that the U-shaped rivets and the locking plates cannot be matched due to inconsistent specifications of the U-shaped rivets.

DETAILED DESCRIPTION

[0042] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Please refer to Figure 1-Figure 6 The utility model provides a U-shaped rivet sorter, which is used to sort qualified U-shaped rivets and assemble U-shaped rivets and lock plates through a material shifter, including an outer bracket 1, an assembly platform 3, a pushing device 4 and a transition device 5, wherein the transition device 5 is installed on the outer bracket 1, and a sorting cylinder group 2 is installed on the top of the outer bracket 1. The sorting cylinder group 2 is composed of a plurality of different cylinders, and a detection mechanism 6 is arranged above the sorting cylinder group 2. The detection mechanism 6 can identify unqualified U-shaped rivets and remove them. The sorting cylinder group 2 is externally connected to a vibrating loader, and the vibrating loader is filled with U-shaped rivets to be assembled. Once the detection mechanism 6 identifies that the U-shaped rivet is unqualified, the accessory is separated. On the other hand, the U-shaped rivets that have been tested and confirmed to be qualified enter the final assembly platform 3 through the transition device 5. The sorting cylinder group 2 and the final assembly platform 3 are respectively placed at the two ends of the transition device 5. The U-shaped rivets can be pushed into the final assembly platform 3 one by one through the transition device 5, and the assembly is completed on the final assembly platform 3. After the assembly is completed, the material mover will move the locking plate and the U-shaped rivet in the final assembly platform 3 into the pushing device 4, and the pushing device 4 will input them into the riveting machine for fixation.

[0044] In this embodiment, if Figure 6, the detection mechanism 6 includes a stand 61 and an elastic damper 63. The stand 61 is vertically arranged on the outer bracket 1, and a guide bar is vertically arranged on the stand 61, a connecting block 62 is slidably arranged on the guide bar, a detection block 64 is installed on the connecting block 62, and a through hole corresponding to the end of the U-shaped rivet is arranged on the detection block 64. During the detection, the sorting cylinder group 2 will lift the U-shaped rivet upward. If the U-shaped rivet can pass through the through hole arranged on the detection block 64, the shape of the U-shaped rivet is qualified. If the U-shaped rivet is against the detection block 64, the force-sensitive resistor on the connection block 62 is sensed, and it is determined that the shape of the U-shaped rivet is unqualified. At this time, the sorting cylinder group 2 puts down the U-shaped rivet, and the material separation cylinder 21 pushes the U-shaped rivet out of the discharge port 24.

[0045] In the previous embodiment, specifically, Figure 4 , the sorting cylinder group 2 includes a sorting cylinder 21, a pneumatic clamp 23 and a discharge port 24. Among them, the sorting cylinder 21 is installed on the upper end of the outer bracket 1 and is arranged on one side of the material moving mechanism 52. The pneumatic clamp 23 is arranged on the other side of the material moving mechanism 52. The bottom of the pneumatic clamp 23 is connected to the lifting cylinder 22 and is driven by the lifting cylinder 22 to move up and down to lift the U-shaped rivet. In this embodiment, the pneumatic clamp 23 is opposite to the sorting cylinder 21, and the discharge port 24 is located between the lifting cylinder 22 and the slide rail 54. When the detection mechanism 6 detects that the size of the U-shaped rivet is unqualified, the unqualified U-shaped rivet is pushed out of the discharge port 24 by the sorting cylinder 21.

[0046] Based on the previous embodiment, Figure 2 If the shape of the U-shaped rivet meets the requirements, the transition device 5 will move the U-shaped rivet to the final assembly platform 3. Specifically, the final assembly platform 3 structure includes a transfer cylinder 31 and an assembly table 33, wherein a transfer slider 34 is installed at the end of the piston rod of the transfer cylinder 31, and a storage groove (not shown in the drawings) is provided on the transfer slider 34. The storage groove is used to connect the linear vibration feeder 53 and move the U-shaped rivet in the linear vibration feeder 53 to the position of the assembly table 33, and then the U-shaped rivet in the transfer slider 34 is pushed into the assembly table 33 by the assembly cylinder 32 installed in front of the assembly table 33, thereby completing the assembly with the lock plate. During this process, the transfer cylinder 31 can drive the transfer slider 34 to move along the length direction of the transfer cylinder 31, thereby transferring the U-shaped rivet in the linear vibration feeder 53, and a positioning clamp 35 is installed at the rear of the assembly table 33. The U-shaped rivet is fixed by the positioning clamp 35 to prevent the U-shaped rivet from shaking due to equipment vibration, thereby causing assembly failure.

[0047] In a specific embodiment disclosed in the present utility model, Figure 2 and Figure 3The transition device 5 includes a material selection cylinder 51 and a material transfer mechanism 52, wherein the material selection cylinder 51 is installed on the outside of the outer bracket 1, and a slide rail 54 is provided at the upper end of the outer bracket 1 to provide a guide for the material transfer mechanism 52.

Specifically, in this embodiment, the first slider 522 and the second slider 525 are both slidably arranged on the slide rail 54, and a transfer groove 524 for moving the U-shaped rivet is provided in the middle of the second slider 525. On the other hand, the material transfer mechanism 52 is slidably arranged on a slide rail 54, which is perpendicular to the material selection cylinder 51. The material selection cylinder 51 is located at the tail end of the linear vibration feeder 53, thereby pushing the U-shaped rivet into the linear vibration feeder 53 and conveying it to the assembly platform 3.

[0048] In some embodiments, the pushing device 4 includes a base frame 41 and a material pushing groove 43, wherein the outer side of the base frame 41 is connected to the assembly platform 3, and a material-moving cylinder 42 is installed on the top of the base frame 41. Since the side of the material pushing groove 43 is adjacent to the material-moving cylinder 42, the material-moving plate 44 can be driven by the material-moving cylinder 42 to slide along the material pushing groove 43, thereby pushing the U-shaped rivets into the riveting machine one by one to complete the fixation.
