Description
Technical Field
[0001] This utility model relates to the field of automatic assembly, specifically to a snap-fit gripper. Background Technology
[0002] Clips are typical components in mechanical engineering that connect parts through locking mechanisms. Their core function is to secure components using elastic deformation and friction. Depending on the application, clips are categorized by shape into direct-insertion, rotary, and press-fit types, and by material, including plastics, metals, and rubber. In industrial manufacturing, clips are widely used in automotive interior parts connections and electronic component assembly due to their tool-free assembly characteristics, although their application is limited by mold precision requirements and structural strength limits.
[0003] Patent CN210010909U discloses a buckle assembly device, including a first arm and a second arm. The middle parts of the first arm and the second arm are rotatably connected by a pivot to form an X shape. One end of the first arm is fixed with a first pair of top members, which are used to laterally press the mounting base. One end of the second arm is fixed with a second pair of top members. The second pair of top members has a fork on the side near the first pair of top members, which is used to cooperate with the neck of the buckle.
[0004] The buckle assembly device requires manual assembly of the buckles, and the buckles can only be assembled one at a time, resulting in low assembly efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a snap-lock gripper that works in conjunction with a robotic arm to simultaneously grasp multiple snaps and transfer them to the assembly position. Then, a push rod is used to press and lock each snap-locker one by one, thereby improving the assembly efficiency of the snap-lockers.
[0006] To achieve the above objectives, this utility model provides a snap-fit gripper, which includes a disc connected to a robotic arm. Multiple radial plates are radially mounted on the outer periphery of the disc. Pneumatic grippers are mounted at the ends of the radial plates. A base plate is mounted on the disc between two adjacent radial plates. A cylinder is mounted on the bottom surface of the base plate, and a push rod is mounted at the end of the cylinder.
[0007] Preferably, an I-shaped flange is installed at the center of the disc, the lower end of the I-shaped flange is bolted to the disc, and the upper end is bolted to the robot arm.
[0008] Preferably, the substrate and the inner end of the radiating plate are both connected to the radiating plate by bolts.
[0009] Preferably, the bottom surface of the substrate is provided with a slide rail, and a slide plate is slidably disposed on the slide rail; an end plate is installed at the outer end of the slide plate, the cylinder shaft of the cylinder is connected to the end plate, and the inner end of the push rod is connected to the end plate through a connecting block.
[0010] Preferably, a bumper is provided on the outer side of the skateboard, and two corner seats are symmetrically arranged on the outer side of the base plate. A limiting buffer that cooperates with the bumper is installed on the corner seat.
[0011] Preferably, the disk has multiple weight-reducing holes spaced at equal intervals along its circumference.
[0012] Preferably, the disc is provided with a positioning groove for limiting the installation of the radiating plate and the substrate.
[0013] According to the above technical solution, the present invention provides a snap-fit gripper, which includes a disc connected to a robotic arm. Multiple radial plates are installed radially on the outer periphery of the disc. Pneumatic grippers are installed at the ends of the radial plates. A base plate is installed on the disc between two adjacent radial plates. A cylinder is installed on the bottom surface of the base plate. A push rod is installed at the end of the cylinder.
[0014] The clip gripper has the following advantages: multiple pneumatic grippers arranged circumferentially can simultaneously grip multiple clips at the gripping position. The robotic arm moves the disc to the assembly position, and after the clips are initially positioned and assembled, the pneumatic grippers are released. The robotic arm then adjusts the disc to a vertical position, so that the push rod is vertically downward. The robotic arm drives the push rod to move to the position of each clip one by one. After aligning the clip, the cylinder extends to push the push rod to press the clip into place. After all clips are installed, the above steps are repeated for the clip assembly of the next workpiece, thus improving the assembly efficiency of the clips.
[0015] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0020] See Figure 1-3 The shown snap-fit gripper includes a disc 2 connected to a robotic arm. Multiple radial plates 4 are radially mounted on the outer periphery of the disc 2. Pneumatic grippers 5 are mounted at the ends of the radial plates 4. A base plate 1 is mounted on the disc 2 between two adjacent radial plates 4. A cylinder 6 is mounted on the bottom surface of the base plate 1. A push rod 8 is mounted at the end of the cylinder 6.
[0021] By implementing the above technical solution, multiple pneumatic grippers 5 arranged circumferentially can simultaneously grip multiple buckles at the gripping position. The robot moves the disc 2 to the assembly position, and after the buckles are initially positioned and assembled, the pneumatic grippers 5 are released. The robot adjusts the position of the disc 2 to a vertical position, so that the push rod 8 is vertically downward. The robot drives the push rod 8 to move to the position of each buckle one by one. After aligning with the buckle, the cylinder 6 extends to push the push rod 8 to press the buckle into place. After all the buckles are installed, the above steps are repeated to assemble the buckles of the next workpiece, which improves the assembly efficiency of the buckles.
[0022] In this embodiment, an I-shaped flange 3 is installed at the center of the disc 2. The lower end of the I-shaped flange 3 is bolted to the disc 2, and the upper end is bolted to the robot arm. This arrangement facilitates the connection between the clamping jaw and the robot arm. The number of axes of the robot arm can be selected as needed and is not limited here. For example, a six-axis robot arm can be used to move the clamping jaw as a whole.
[0023] In this embodiment, both the substrate 1 and the inner end of the radiating plate 4 are connected to the radiating plate 4 by bolts. This arrangement enables the radiating plate 4 to be detachable.
[0024] In this embodiment, a slide rail 13 is provided on the bottom surface of the base plate 1, and a slide plate 9 is slidably mounted on the slide rail 13; an end plate 7 is installed on the outer end of the slide plate 9, the cylinder shaft of the cylinder 6 is connected to the end plate 7, and the inner end of the push rod 8 is connected to the end plate 7 through a connecting block 16. This arrangement, using the sliding engagement between the slide plate 9 and the slide rail 13, provides stability when the push rod 8 is pressed and latched.
[0025] In this embodiment, a bumper 10 is provided on the outer side of the slide plate 9, and two corner seats 11 are symmetrically arranged on the outer side of the base plate 1. A limiting buffer 12 that cooperates with the bumper 10 is installed on the corner seat 11. With this arrangement, the bumper 10 cooperates with the limiting buffers 12 at both ends to provide limiting at both ends.
[0026] In this embodiment, the disk 2 is provided with a plurality of weight-reducing holes 14 at equal intervals along its circumference. This arrangement reduces the overall weight and decreases the burden on the robotic arm.
[0027] In this embodiment, the disc 2 is provided with positioning grooves 15 for limiting the installation of the radiating plate 4 and the substrate 1. The positioning grooves 15 of the two are of different specifications, mainly to enable quick positioning when installing the radiating plate 4 and the substrate 1.
[0028] In one practical application, five pneumatic grippers 5 are arranged in a row, with an included angle of 60° between adjacent pneumatic grippers 5. A base plate 1 is provided between the pneumatic grippers 5 at the beginning and end, and the included angle between the base plate 1 and the pneumatic grippers 5 at the beginning and end is also 60°.
[0029] The vibratory feeder in the vibratory feeding system is activated, arranging the clips in an orderly manner and conveying them to the designated feeding area. The clips' posture is ensured to meet the gripping requirements. Then, the vision system in the workshop captures and analyzes the images of the clips in the feeding area, determining the precise coordinates of five clips to be gripped. Based on the coordinates provided by the vision system, the robotic arm controls the pneumatic gripper 5 to move to the corresponding position, accurately gripping the five clips. The robotic arm carries the five gripped clips to the target placement station, accurately placing the clips in the designated position. The cylinder 6 pushes the push rod 8 to press the five placed clips, bringing them to the required state. After one round of gripping and pressing, the robotic arm returns to its initial position, ready for the next gripping. The vibratory feeder continues to feed, repeating the above process.
