Description

[Technical field]

[0001] The invention relates to the technical field of nut placement and feeding, in particular to a nut placement fixture with adjustable angle. [Background technology]

[0002] Threaded connection is one of the most commonly used connection structures for plastic parts. By embedding nuts directly in the plastic part molding mold when molding the plastic part, the nuts can be firmly fixed to the molded plastic part. Due to structural requirements, the embedded nuts sometimes need to be designed to have a certain tilt angle, and the nuts are in a vertical direction when they come down from the vibration plate. The placement mechanism of the vibration plate cannot directly place the nuts at the designed tilt angle, resulting in the subsequent robot arm being unable to place the nuts into the mold according to the designed tilt angle, affecting the automation process. The current solution is to use hot melt to melt the nuts into the plastic part at an inclined angle after the plastic part is molded, but this will reduce the tensile torsional force of the nut by about 20%, and the bonding strength between the nut and the plastic part cannot be guaranteed, which in turn leads to customer complaints and other adverse situations.

[0003] In view of this, the present invention provides a nut placement fixture with adjustable angle to solve the above problems. [Summary of the invention]

[0018] To further illustrate the technical means and effects adopted by the present invention, the following is a detailed description in conjunction with the embodiments of the present invention and the accompanying drawings.

[0019] The present invention provides a nut placing jig with an adjustable angle, which is used to place nuts conveyed by a vibrating plate, and the nut placing jig comprises:

[0020] A bottom plate 1, on which a plurality of first positioning columns 10 are arranged, and the first positioning columns 10 are vertically fixed to the bottom plate 1 for positioning nuts placed in a vertical direction, and a plurality of hollow portions 11 are also arranged on the bottom plate 1, and a first fixing block 12 and a second fixing block 13 are also arranged on the other side of the bottom plate 1 opposite to the side on which the first positioning columns 10 are arranged;

[0021] The adjustable angle positioning mechanism 2 comprises an angle adjustment device 20, a pushing device 21, and a second positioning column 22, wherein:

[0022] One end of the angle adjustment device 20 is mounted on the first fixed block 12, and the driving end 200 of the angle adjustment device 20 is connected to a matching plate 210, and the matching plate 210 is rotatably mounted on the second fixed block 13 via a rotating shaft (not shown in the figure);

[0023] The pushing device 21 is fixed to the matching plate 210. When the driving end 200 of the angle adjustment device 20 drives the matching plate 210 to perform telescopic movement, the matching plate 210 can rotate relative to the second fixing block 13, that is, at this time, the pushing device 21 can rotate relative to the bottom plate 1;

[0024] The second positioning column 22 includes a sleeve 220 and a ejector pin 221, wherein the sleeve 220 is inserted into the ejector pin 221, wherein the sleeve 220 is fixed to the pushing end 211 of the pushing device 21 through a connecting block 23, and the ejector pin 221 is fixed to the matching plate 210. The second positioning column 22 can extend from the hollow portion 11, and is used to position a nut placed in an inclined direction.

[0025] Wherein, the angle adjustment device 20 and the pushing device 21 are both cylinders.

[0026] Among them, a slide seat 14 is provided on the base plate 1, and the base plate 1 is slidably set on a slide rail 3 through the slide seat 14. A driving device 30 is provided on the slide rail 3. The driving device 30 is connected to the slide seat 14 and is used to drive the base plate 1 to slide along the slide rail 3, so as to facilitate the vibration plate to convey nuts and the robot to adjust the position of the fixture when taking nuts.

[0027] The working process of the present invention is as follows: first, the angle adjustment device 20 is adjusted to make the driving end 200 of the angle adjustment device 20 extend and retract until the second positioning column 22 is in a vertical state relative to the bottom plate 1, and the driving device 30 on the slide rail 3 drives the bottom plate 1 of the nut placement fixture to slide under the nut vibration plate, and the nuts to be placed are sequentially unloaded by the placement mechanism on the vibration plate and placed on the first positioning column 10 and the second positioning column 22 on the bottom plate 1;

[0028] Next, the angle adjustment device 20 is adjusted again to tilt the second positioning column 22 to the designed embedding angle required for the nut. At this time, the driving device 30 on the slide rail 3 drives the nut placement fixture to the nut removal robot again. The robot adjusts the material removal direction according to the angle of each nut on the nut placement fixture and absorbs the nut. When the robot absorbs the nut on the second positioning column 22, the pushing end 211 of the pushing device 21 drives the sleeve 220 to be pushed out toward the robot to assist the robot in removing the nut on the ejector pin 221.

[0029] The beneficial effect of the present invention is that the nut placement fixture with adjustable angle of the present invention can realize the placement of nuts at multiple angles, and can be linked with other equipment such as nut vibration plates, nut removal robots and other automated equipment, so as to realize the automated operation of nut embedding and speed up the automated operation process. The fixture has a simple structure, is easy to operate and maintain.

[0030] It should be pointed out that the present invention is not limited to the above-mentioned implementation modes, and any simple modifications, equivalent changes and modifications made to the above-mentioned embodiments by any technician familiar with the profession based on the technical solution of the present invention fall within the protection scope of the present invention.
