Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0034] As shown in the drawings, Figures 1-4 The present application provides a technical solution: a high-precision SMT patch positioning mechanism, comprising:
[0035] The bearing table assembly 1 is composed of a bearing frame 11, a magnetic attraction device 14, a magnetic attraction plate 13 and an anti-static plate 12. The magnetic attraction device 14, the magnetic attraction plate 13 and the anti-static plate 12 are sequentially arranged on the bearing frame 11.
[0036] The anti-static assembly 2 is composed of fixed plates 21 arranged on both sides of the bearing frame 11. There are four fixed plates 21 in total, and two fixed plates 21 form a group. The two groups of fixed plates 21 are symmetrically arranged with respect to the center of the bearing frame 11. A connecting rod 22 is arranged between the two fixed plates 21. A sliding sleeve 23 is slidingly connected to the connecting rod 22. An arm ring 25 is arranged on the sliding sleeve 23. A resistance rope 24 is arranged between the sliding sleeve 23 and the arm ring 25.
[0037] The diameters and widths of the magnetic attraction plate 13 and the anti-static plate 12 are adapted to the inner wall of the bearing frame 11. The magnetic attraction device 14 transmits magnetic force to the anti-static plate 12, and the material is adsorbed. The small material is always on the anti-static plate 12, avoiding displacement of the material on the anti-static plate 12 during processing. Further, under the action of the anti-static plate 12, static electricity generated during material processing is avoided, and material damage caused by static electricity during processing is avoided.
[0038] Further, as shown in the drawings, Figure 2 Figure 4 The limiting assembly 3 is composed of the first elastic plate 31 and the second elastic plate 32 arranged between the mounting frame 15 and the bearing frame 11, the limiting sleeve 33 is arranged between the first elastic plate 31 and the second elastic plate 32, the two sides of the limiting sleeve 33 are provided with the springs 34 connected with the first elastic plate 31 and the second elastic plate 32, the diameter of the connecting rod 22 is matched with the diameter of the sliding sleeve 23, the bottom of the mounting frame 15 is provided with the mounting bolt 151 penetrating the magnetic attraction device 14, the connecting plate 16 is arranged between the mounting frame 15 and the bearing frame 11, the four connecting plates 16 are arranged in a rectangular distribution, and the included angles between the adjacent two connecting plates 16 are equal, and the four sides of the magnetic attraction device 14 are limited under the action of the limiting assembly 3, so that the displacement of the magnetic attraction device 14 during use is avoided, the magnetic force changes, and the material on the anti-static plate 12 is displaced, the first elastic plate 31 is extruded and limited to the outer wall of the magnetic attraction device 14 through the mutual reverse expansion of the second elastic plate 32 and the second elastic plate 32, the displacement of the magnetic attraction device 14 during use is avoided, and the service life of the first elastic plate 31 and the second elastic plate 32 is improved under the action of the spring 34.
[0039] The above scheme also has the problem that the spring 34 is easily separated from the first elastic plate 31 and the second elastic plate 32 during use, such as Figure 3 As shown in the scheme, the rotating column 35 is arranged below the limiting sleeve 33 on the connecting plate 16, and the limiting sleeve 33 is rotationally connected to the rotating column 35. The rotating column 35 arranged on the connecting plate 16 limits the limiting sleeve 33, so that the limiting sleeve 33 is not separated from the rotating column 35 during use, and the fixing effect of the limiting assembly 3 on the magnetic attraction device 14 is weakened.
[0040] The above scheme also has the problem that the magnetic attraction device 14 adsorbs the lower material or impurities, such as Figure 3 As shown in the scheme, the supporting legs 17 are arranged at the bottom of the bearing frame 11, the four supporting legs 17 are arranged in a rectangular distribution, and the included angles between the adjacent two supporting legs 17 are equal. Under the action of the supporting legs 17, the device is installed on the designated position, and the bearing frame 11 and the mounting surface always reserve a certain movement space through the supporting legs 17, so that the lower micro material or impurities are adsorbed under the action of the magnetic attraction device 14.
[0041] Working principle:
[0042] As Figures 1-4As shown, first, the carrier frame 11 is erected and installed at the designated position through the support feet 17, second, the material is put on the anti-static plate 12 through the material feeding assembly, under the action of the anti-static plate 12, the material is prevented from generating static electricity when being fed or clamped, further, the magnetic attraction plate 13 generates magnetic force through the setting of the magnetic attraction device 14, the generated magnetic force is adsorbed and fixed to the material after passing through the anti-static plate 12, the material is prevented from being displaced before being clamped, so that the clamping fails, after the device is maintained and repaired, the arm ring 25 is sleeved on the hands of the maintenance personnel, then the equipment is operated, so that the static electricity is prevented from damaging the magnetic attraction device 14 in the process of repairing.
[0043] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
