[0056] Figure 1 is a schematic structural diagram of a fastening device 100 according to an embodiment of the present disclosure. Figure 2 2 is a schematic structural diagram of a fastening device 100 according to an embodiment of the present disclosure from another angle.

[0057] like Figure 1 and Figure 2As shown, the snap-fit ​​device 100 of the present disclosure may include: a retaining component 110 , a moving component 120 , a guiding component 130 , a driving device 140 and other components.

[0058] The holding component 110 is used to hold the workpiece to be assembled; in a preferred embodiment, the holding component 110 may be a vacuum suction device, and the workpiece to be assembled may be a workpiece with a plane such as a shell, so that the workpiece can be adsorbed by the holding component 110. Of course, the holding component 110 of the present disclosure may also be a clamping device, etc., which is not limited in the present disclosure.

[0059] The holding component 110 can be arranged on the moving component 120. In one embodiment, the holding component 110 can be fixed on the moving component 120 and can move with the moving component 120. In particular, in the present disclosure, by separately arranging the holding component 110 and the moving component 120, the holding component 110 can be easily replaced, thus saving downtime due to replacement of the holding component 110 and improving production efficiency.

[0060] The guide component 130 is used to guide the moving component 120 and enable the moving component 120 to rotate around a preset axis; accordingly, when the moving component 120 rotates, the retaining component 110 can also move synchronously.

[0061] In the present disclosure, the preset axis is located at or near a side of the workpiece held by the holding component 110, so that the holding component 110 can operate the workpiece and insert a side portion of the workpiece at a predetermined position. Then, the holding component 110 rotates around the preset axis so that the workpiece is fastened to other parts, thereby completing the assembly of the entire product.

[0062] In one embodiment, the moving component 120 can be driven to rotate by the driving device 140. That is, the driving device 140 can provide a driving force to the moving component 120 and make the moving component 120 rotate.

[0063] In the present disclosure, the snap-fitting device 100 also includes a support member 150. In a preferred embodiment, the support member 150 is L-shaped, that is, the support member 150 includes a horizontal portion and a vertical portion that are vertically connected to each other or approximately vertically connected. Accordingly, the guide member 130 can be fixed to the horizontal portion of the support member 150 and is located below the horizontal portion of the support member 150.

[0064] Figure 3 It is a structural schematic diagram of a partial structure of a fastening device according to an embodiment of the present disclosure. Figure 4It is a schematic structural diagram of a guide device according to one embodiment of the present disclosure. Figure 5 It is a schematic structural diagram of a moving part according to an embodiment of the present disclosure.

[0065] In a specific embodiment, the driving device 140 may be a cylinder. Of course, the driving device 140 may also be other components.

[0066] The driving device 140 can be installed on the support member 150, and more specifically, the driving device 140 is fixed to the vertical portion of the support member 150. For example, the cylinder body of the cylinder can be hinged to the vertical portion of the support member 150, and the piston rod of the cylinder can be hinged to the moving component 120, so that when the piston rod is extended or retracted, the moving component 120 can generate a rotational motion.

[0067] like Figure 4 As shown, in the present disclosure, the guide component 130 is generally U-shaped and includes a connecting portion and two parallel and spaced side walls, wherein the two side walls are connected to the lower surface of the connecting portion and are located at two ends of the connecting portion. Accordingly, the moving component 120 can be at least partially disposed in the area between the two side walls.

[0068] The guide component 130 is provided with an arc-shaped guide groove 131, and the center of the arc-shaped guide groove 131 is located on the preset axis. In a specific embodiment, two arc-shaped guide grooves 131 are provided, and the two arc-shaped guide grooves 131 have the same center, thereby enabling the motion component 120 of the present disclosure to move more smoothly.

[0069] In the present disclosure, the arc-shaped guide groove 131 can be provided on the side wall of the guide component 130, and the arc-shaped guide groove 131 is provided on both side walls, and in particular, the arc-shaped guide grooves 131 of the two side walls can be located at the same position in the horizontal direction.

[0070] The moving component 120 is provided with a rolling element 121, and the rolling element 121 is configured to be able to move in the arc-shaped guide groove 131. Preferably, the rolling element 121 may be a cam follower.

[0071] More specifically, two rolling elements 121 are arranged in at least one arcuate guide groove 131; in a preferred embodiment, two rolling elements 121 are arranged in each arcuate guide groove 131; moreover, the moving component 120 has a first position and a second position when rotating, and the arcuate guide groove 131 includes a first end and a second end, wherein, when the moving component 120 is located at the first position, one of the rolling elements 121 arranged in the arcuate guide groove 131 is located at the first end of the arcuate guide groove 131; when the moving component 120 is located at the second position, the other rolling element 121 arranged in the arcuate guide groove 131 is located at the second end of the arcuate guide groove 131.

[0072] In a more preferred embodiment, the arc-shaped guide groove 131 has a highest point, and when the moving component 120 is located in the first position, another rolling element 121 arranged in the arc-shaped guide groove 131 is located at or near the highest point of the arc-shaped guide groove 131; correspondingly, when the moving component 120 is located in the second position, one of the rolling elements 121 arranged in the arc-shaped guide groove 131 is located at or near the highest point of the arc-shaped guide groove 131, so that the driving device 140 can conveniently drive the moving component 120 to move.

[0073] In the present disclosure, a first limiting device 160 is provided on the guide component 130, and the first limiting device 160 is used to limit the moving component 120 to a first position; wherein, when the moving component 120 is located at the first position, the workpiece to be assembled can be in a substantially horizontal position.

[0074] Among them, the first limiting device 160 can be directly or indirectly set on the guide component 130; when the first limiting device 160 is indirectly set on the guide component 130, the first limiting device 160 can be set on the support member 150, and at this time, the position between the first limiting device 160 and the guide component 130 can be kept fixed.

[0075] The guide component 130 is provided with a second limit device 170, which is used to limit the moving component 120 to a second position, wherein in the second position, the workpiece to be assembled can be in a 35° inclined position, that is, the workpiece to be assembled can form an angle of approximately 35° with the horizontal plane.

[0076] That is to say, in the present disclosure, by providing the first limiting device 160 and the second limiting device 170 , the workpieces to be assembled can be loaded to a preset angle, thereby meeting different relative angle requirements of the two products to be assembled before assembly.

[0077] The snap-fitting device 100 also includes a connector 180, which is slidably disposed on the support member 150, and a pressure sensor 190 is disposed between the connector 180 and the support member 150. When the connector 180 moves relative to the support member 150, the pressure between the support member 150 and the connector 180 is detected by the pressure sensor 190.

[0078] Specifically, a guide rail is disposed on the vertical portion of the support member 150 , and the guide rail is disposed along the vertical direction. The connector 180 can be slidably disposed on the guide rail, so that the connector 180 and the support member 150 can move relative to each other.

[0079] In actual use, the connector 180 can be fixed to the end of a mechanical arm so that the snap-fit ​​device of the present disclosure can be driven and moved by the mechanical arm.

[0080] In a specific embodiment, a fixing seat 195 is installed on the connector 180 . The fixing seat 195 may be L-shaped and has a through hole.

[0081] The height-contact screw 191 passes through the through hole of the fixing seat 195, and the screw head of the height-contact screw 191 is located above the through hole of the fixing seat 195; the lower end of the height-contact screw 191 is connected with a pressing block 192, and the pressing block 192 can contact the pressure sensor 190. Preferably, a threaded hole is provided on the pressing block 192, and the lower end of the height-contact screw 191 can be screwed into the threaded hole, and the distance between the pressing block 192 and the fixing seat 195 can be adjusted by the depth of the height-contact screw 191 screwed into the threaded hole of the pressing block 192.

[0082] The pressure sensor 190 is arranged between the support member 150 and the pressure block 192. Therefore, when an external force is applied to the workpiece to be assembled so that the support member 150 moves upward, the support member 150 can apply pressure to the pressure sensor 190, thereby accurately detecting the force applied to the workpiece by the retaining component 110 through the pressure sensor, that is, detecting the size of the snap-fitting force, to prevent the force from being too large and damaging the workpiece or product.

[0083] More preferably, a spring is sleeved on the equal height screw 192, one end of the spring can be mounted on the pressure block 192, and the other end can be mounted on the connector 180, so that the pressure detection structure of the present disclosure can have a certain buffering function, thereby the force applied to the workpiece can be gradually increased.

[0084] In the present disclosure, the snap-fitting device 100 may further include an anti-drop plate 194, one end of which is fixed on the support member 150, and the other end of which cooperates with the fixing seat 195 and limits the upward movement position of the fixing seat 195. In other words, through the setting of the anti-drop plate 194, the downward movement position of the support member 150 can be limited.

[0085] In addition, a sensing plate 193 may be provided on the connector 180 of the present invention, so that when the snap-fit ​​device 100 is installed on the robotic arm, the snap-fit ​​device can be installed at a preset position at the end of the robotic arm by aligning the sensing plate 193 with the corresponding position of the end of the robotic arm.

[0086] When the buckling device disclosed in the present invention is used, the number of the buckling devices can be flexibly configured. For example, the buckling devices can be arranged in multiple rows and columns. Since they have the same structure and the same action, the production rhythm of the equipment can be improved.

[0087] The snap-fit ​​device disclosed in the present invention is connected to the robot arm via a connector (R-axis connector), and can correct the rotation direction around the Z-axis.
