Description

Technical Field

[0001] The utility model relates to the technical field of knocking equipment, in particular to a knocking device. Background Art

[0002] When testing chips, a chip test sorter needs to place them in a chip tray. The chip tray is positioned between two rails. Because the robot often places chips on the tray, placement errors often occur. The existing solution uses a pneumatic cylinder to strike the rails, vibrating the chip tray and returning the chips to their correct position. However, because the cylinder strikes the rails directly, indirectly affecting the chip tray, this method results in uneven vibration and low transmission efficiency, resulting in unsatisfactory chip alignment.

[0003] In addition, since different knocking angles and knocking positions are used to knock on the chip tray, different vibration effects will be produced on the chip tray, which will affect the chip's return effect. For example, when knocking on the tray chip horizontally, the vertical vibration of the tray chip is small, while knocking at an angle will increase the vertical vibration of the chip tray and improve the vibration effect. However, when knocking vertically up and down, the horizontal vibration of the chip tray and the diffusion from the knocking position to other directions are poor. Therefore, it is necessary to adjust the appropriate knocking angle to ensure good vibration in both horizontal and vertical directions. For example, when knocking on different positions of the chip tray, the vibration at the knocking position is larger, and the part of the chip tray farther away from the knocking position vibrates less. Adjusting the knocking position according to the placement of the chip on the chip tray can better achieve the chip return effect. However, the existing knocking device is direct knocking by a cylinder, and the cylinder position is fixed. The knocking position and knocking angle cannot be adjusted arbitrarily, which affects the knocking effect. Utility Model Content

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1, reference Figure 1-5 , which is the first embodiment of the present utility model, provides a striking device, including

[0028] Bracket 100;

[0029] The striking mechanism 200 includes a first hinge 201 and a limiting assembly 202 . The first hinge 201 is hinged to the bracket 100 .

[0030] The driving mechanism 300 includes an air jet 301 . The air jet 301 and the limiting assembly 202 are respectively arranged on both sides of the first hinge piece 201 , and the air jet 301 faces the first hinge piece 201 .

[0031] The bracket 100 serves as the supporting structure of the entire device, and the knocking mechanism 200 is installed on the bracket 100. Through the driving mechanism 300 and the limit assembly 202, the first hinge piece 201 swings back and forth, knocking the chip tray during the swinging process to return the chip to the right position. Specifically, the air jet 301 is an intermittent air jet, of course, it ejects high-pressure air. When the air jet 301 ejects air, the first hinge piece 201 is impacted by the airflow and swings upward. When it swings to contact with the limit assembly, it knocks on the chip tray. Then, due to the action of gravity, the first hinge piece swings back downward, and the cycle continues.

[0032] Furthermore, the knocking mechanism 200 further includes a second hinge piece 203 . The second hinge piece 203 is disposed on the bracket 100 , and the first hinge piece 201 and the second hinge piece 203 are hinged.

[0033] The second hinge piece 203 and the first hinge piece 201 form a combined hinge structure. The second hinge piece 203 is used to connect with the bracket. The first hinge piece 201 and the second hinge piece 203 are hinged and used to swing and knock the chip tray.

[0034] Furthermore, the knocking mechanism 200 further includes a contact block 204 . The contact block 204 is disposed on a side of the first hinge piece 201 away from the air jet 301 . The contact block 204 is an elastic member.

[0035] The first hinge 201 is in direct, hard contact with the chip tray. Continuous impact can easily cause deformation or even damage to the first hinge 201 and the chip tray. Therefore, an elastic contact block 204 is provided on the first hinge 201 to contact the chip tray, thereby reducing damage to the chip tray and the first hinge 201 and reducing maintenance frequency. The contact block 204 is made of elastic plastic or rubber.

[0036] Furthermore, the limiting assembly 202 includes a column 202 a and a limiting plate 202 b . The column 202 a is disposed on the second hinge piece 203 , and the limiting plate 202 b is disposed at an end of the column 202 a away from the second hinge piece 203 .

[0037] The column 202a is arranged on the side of the first hinge 201 away from the air outlet 301, and the upper end is detachably installed with a limit plate 202b, wherein the limit plate 202b is a rectangular plate extending toward the first hinge 201. When the first hinge 201 rotates to the side where the limit assembly 202 is located, the limit plate 202b prevents the first hinge 201 from continuing to rotate, and the first hinge swings back due to gravity.

[0038] Furthermore, the driving mechanism 300 also includes an air inlet 302, a cavity 303, a rotating shaft 304, an impeller 305 and a sealing plate 306. The rotating shaft 304, the impeller 305 and the sealing plate 306 are all located in the cavity 303. The cavity 303 is arranged at the lower part of the bracket 100. The air jet 301 is connected to the inside of the cavity 303. The rotating shaft 304 is rotatably arranged on the bracket 100. The impeller 305 is arranged at the lower end of the rotating shaft 304. The air outlet end of the air inlet 302 is opposite to the impeller 305. The sealing plate 306 is an annular plate, and the sealing plate 306 is coaxially fixed to the upper end of the rotating shaft 304. The air jet 301 is located on the rotation path of the sealing plate 306. A notch 306a is provided on the sealing plate 306. The width of the notch 306a is greater than the aperture of the air jet 301.

[0039] Usage process: the air inlet 302 sprays high-pressure gas into the cavity 303 and directly sprays it onto the impeller 305, driving the impeller 305 to rotate, and then driving the blocking plate 306 to rotate. After the notch 306a and the air jet 301 overlap, the high-pressure gas is ejected from the air jet 301, impacting the first hinge piece 201, driving the first hinge piece 201 to swing. When it swings to the limit plate 202b, the limit plate 202b blocks the first hinge piece 201 from continuing to rotate. The first hinge piece 201 swings downward under the action of the contact block 204 and the gravity of the first hinge piece 201. At the same time, the blocking plate 306 continues to rotate to block the air jet 301, preventing the air jet from blocking the first hinge piece 201 from swinging back, and the cycle continues.

[0040] The first hinge piece 201 drives the contact block 204 to directly knock the chip tray, which makes the vibration more uniform, the transmission more efficient, and improves the chip return effect. The elastic contact block 204 contacts the chip tray without leaving knock marks, avoiding damage.

[0041] Example 2, reference Figure 2 , which is the second embodiment of the present utility model. Different from the previous embodiment, the driving mechanism 300 further includes an airbag 307 , and the airbag 307 is connected to the interior of the cavity 303 .

[0042] When the sealing plate 306 blocks the jet port 301, the gas entering the cavity 303 from the air inlet 302 enters the airbag 307, preventing the internal air pressure of the cavity 303 from being too high. At the same time, when the jet port 301 ejects air, the airbag 307 contracts, causing the gas in the airbag 307 to be ejected together, thereby increasing the ejection pressure and thereby increasing the knocking force to ensure the knocking effect.

[0043] Furthermore, the airbag 307 is disposed on the upper portion of the bracket 100 , and the first hinge piece 201 is located directly above the airbag 307 .

[0044] The airbag 307 is arranged at the lower part of the first hinge piece 201. When the first hinge piece 201 swings back, due to the blocking of the air outlet 301 by the blocking plate 306, the airbag 307 is in an inflated state, and the first hinge piece 201 falls on the airbag 307 to form a buffer, thereby preventing the first hinge piece 201 from directly hitting the bracket 100 when swinging back, and preventing the first hinge piece 201 and the bracket 100 from being deformed and damaged due to collision.

[0045] Furthermore, a pressure relief valve 307 a is provided on the airbag 307 .

[0046] The pressure relief valve 307a is provided to discharge the gas when the internal pressure is too high.

[0047] Usage process: When the sealing plate 306 blocks the air jet 301, part of the gas entering the cavity 303 from the air inlet 302 enters the airbag 307 to prevent the internal air pressure of the cavity 303 from being too high. At the same time, when the air jet 301 is ejected, the gas in the airbag 307 is ejected to increase the injection pressure. When the first hinge piece 201 swings back, due to the blocking of the air jet 301 by the sealing plate 306, the airbag 307 is inflated, and the first hinge piece 201 falls on the airbag 307 to form a buffer.

[0048] Example 3, reference Figure 3 , which is the third embodiment of the present utility model. Different from the previous embodiment, the bracket 100 is an inverted U-shaped structure, and a flange 101 is provided at the lower end of the bracket 100.

[0049] Furthermore, a magnet block 102 is provided at the lower portion of the flange 101 .

[0050] Usage process: A magnet block 102 is set at the lower end of the bracket 100, and the magnet block 102 is adsorbed between the rails to fix the position of the entire device; the entire device is fixed by magnetic adsorption, and the position of the device can be adjusted at will, thereby adjusting the knocking position and angle.
