Description

Technical Field

[0001] The utility model relates to the field of installation jigs, and more specifically, to a jig for placing diaphragms. Background Art

[0002] The automatic assembly process of voice coils and diaphragms usually uses a jig to load and position the voice coils, and then a suction cup is used to pick up the diaphragm and apply glue around the diaphragm. Finally, the diaphragm is adhered to the voice coil to complete the assembly of the voice coil and the diaphragm. However, since the diaphragm is square, small in area and thin, in order to improve the efficiency of picking up the diaphragm, multiple diaphragms are usually stacked and then picked up one by one by the suction cup. However, during the process of picking up the diaphragm by the suction cup, multiple diaphragms are often picked up, resulting in multiple diaphragms being adhered to one voice coil, causing the voice coil to be unusable. Therefore, how to make the suction cup pick up only one diaphragm at a time is a technical problem that needs to be solved urgently. Summary of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a jig for placing diaphragms, aiming to solve the problem of how to make the suction cup pick up only one diaphragm at a time.

[0004] The utility model is realized as follows: A jig for placing diaphragms includes a base. The base is provided with a plurality of square grooves, and the base is provided with a plurality of circular grooves around the square grooves. The circular grooves communicate with the square grooves. A positioning post is arranged in the circular groove, the bottom of the positioning post is fixed at the bottom of the circular groove, and a brush is installed on the positioning post, and the brush extends into the square groove.

[0005] Further, a cover plate is arranged at the upper end of the base. The cover plate is provided with a square hole, and the area of the square hole is smaller than the cross-sectional area of the square groove.

[0006] Further, the brush is installed on one side of the positioning post close to the cover plate.

[0007] Further, a strip hole is further opened on the side surface of the square groove.

[0008] Further, there are four circular grooves, which are respectively arranged at the four corners of the square groove. A positioning post is arranged in each circular groove, and a brush is installed on the positioning post.

[0009] Further, there are 4 - 6 square grooves, and correspondingly, there are 4 - 6 square holes.

[0010] The beneficial effects of the utility model are:

[0011] The fixture for placing diaphragms of the present utility model has a simple structure and is ingeniously designed. It includes a base. The base is provided with a number of square grooves, and several circular grooves are formed around the square grooves. The circular grooves communicate with the square grooves. Positioning columns are arranged in the circular grooves, the bottoms of the positioning columns are fixed to the bottoms of the circular grooves, and brushes are installed on the positioning columns, with the brushes extending into the square grooves. When in use, the stacked diaphragms are placed in the square grooves. The suction cup extends into the square grooves to suck the diaphragms and then is lifted upward. During the lifting process, under the action of the bristles of the brushes, multiple diaphragms are brushed off, and only one diaphragm closest to the suction cup on the top is retained, thus achieving the effect of picking up one diaphragm at a time and preventing the voice coil from being unusable due to the adhesion and installation of multiple diaphragms on one voice coil.

[0023] Please refer to Figures 1-4, the present utility model provides a jig for placing diaphragms, which includes a base 10. The base 10 is provided with a plurality of square grooves 101. The stacked diaphragms are placed into the square grooves 101. The square grooves 101 include 4 - 6, and multiple stacks of diaphragms can be placed at one time for corresponding multiple suction cups to pick up. In this embodiment, 6 square grooves 101 are provided, which can be picked up by 6 suction cups. The base 10 is provided with a plurality of circular grooves 102 around the square grooves 101. The circular grooves 102 communicate with the square grooves 101. Positioning columns 1021 are arranged in the circular grooves 102. The bottom of the positioning columns 1021 is fixed to the bottom of the circular grooves 102. Brushes 1022 are installed on the positioning columns 1021, and the brushes 1022 extend into the square grooves 101. Specifically, the brushes 1022 are installed on one side of the positioning columns 1021 close to the cover plate 20. There are no bristles installed on the lower side of the positioning columns 1021. The stacked diaphragms are placed in the space without brushes 1022 at the bottom of the circular grooves 102. After the suction cup extends into the square groove 101 to suck the diaphragm and then moves upward, it passes through the brushes 1022 on the upper side of the positioning columns 1021. The brushes 1022 brush off the diaphragms sucked by the suction cup, so that multiple diaphragms will fall into the square groove 101, and only the first diaphragm sucked by the suction cup will not fall, realizing the function of only sucking one diaphragm at a time. Further, there are four circular grooves 102, which are respectively arranged at the four corners of the square groove 101. A positioning column 1021 is arranged in each circular groove 102, and a brush 1022 is installed on the positioning column 1021. The four positioning columns 1021 around the four corners of the square groove 101 can brush the diaphragms sucked by the suction cup at four positions, further ensuring that multiple diaphragms are brushed off, and only one diaphragm is left to be taken out onto the voice coil.

[0024] Please refer to Figures 1-4 , a cover plate 20 is arranged at the upper end of the base 10. The cover plate 20 is provided with a square hole 201. The area of the square hole 201 is smaller than the cross-sectional area of the direction groove. When the diaphragm comes out of the square groove 101 and then passes through the square hole 201, since the area of the square hole 201 is smaller than the cross-sectional area of the direction groove, the four sides of the square hole 201 will screen the four sides of the diaphragm again, blocking the multiple diaphragms adsorbed on the bottom of the first diaphragm and falling them back into the square groove 101, further ensuring the effect that the suction cup only sucks one diaphragm.

[0025] In addition, a strip hole 103 is further opened on the side of the square groove 101, which is used for observing whether there are still diaphragms at the bottom of the square groove 101 on the one hand, and observing the situation of the suction cup sucking the diaphragm on the other hand.

[0026] The above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
