[0041] In the prior art, small-sized chips are not easy to be picked up and placed by a picking tool such as a tweezers during cleaning, and the chip surface is easily scratched during picking up and placing. Therefore, the application opens a picking and placing groove 130 at a position of a side surface of the placing groove 120 in an opposite direction, so that the two clamping legs of the tweezers are located in the picking and placing grooves 130 on both sides of the chip, the chip is clamped on both sides, the chip is picked up, and the chip surface is not easily scratched.
[0042] The chip cleaning jig 100 includes a bearing member 110 and a jig picking and placing device 200. The bearing member 110 has a plurality of placing grooves 120. At least one side surface of the placing groove 120 in an opposite direction has a picking and placing groove 130. The bottom surface of the placing groove 120 has at least one liquid passing hole 140 that penetrates the bearing member 110. The jig picking and placing device 200 is located on one side of the bearing member 110 and is used for picking and placing the bearing member 110.
[0043] The bearing member 110 is a circular plate body. The bearing member 110 can also have other shapes, such as a quadrilateral, a pentagon, a hexagon, etc. The shape of the bearing member 110 is not limited.
[0044] In this embodiment, a plurality of chips are placed in the bearing member 110. In order to facilitate the placement of the chip-loaded jig into a cleaning machine for cleaning, the jig picking and placing device 200 drives the bearing member 110 to move for picking up and placing, so that the bearing member 110 is placed into and taken out of the cleaning machine.
[0045] Referring to FIGS. 1, 2, and 3, Figure 1 and Figure 2 The upper surface of the bearing member 110 has a plurality of placing grooves 120, and the placing grooves 120 are uniformly distributed about the center of the bearing member 110. The shape and size of the placing groove 120 can be set according to the size of the chip. The shape of the placing groove 120 is exemplarily illustrated as a rectangle. In order to facilitate the placement of the chip into the placing groove 120 and the taking out of the chip from the placing groove 120, a picking and placing groove 130 is opened on the side surface of the placing groove 120 in an opposite direction. When the chip is picked up and placed, the clamping leg of the picking tool can be deeply inserted into the picking and placing groove 130 in the opposite direction, so that the chip is clamped between the two clamping legs. When the chip is placed or taken out, the chip can be clamped and placed by the two clamping legs, that is, the clamping force is applied to the side edge of the chip, so that the chip surface is not easily scratched and damaged.
[0046] In some embodiments, the placing grooves 120 are provided with taking and placing grooves 130 in four directions of front, back, left and right. If the placing grooves 120 are polygons with more than four sides, the taking and placing grooves 130 should be provided at the positions of each side, so that the chip can be taken out from any direction.
[0047] Further, in order to completely immerse the chip in the placing grooves 120 into the cleaning liquid, a surrounding part 160 is provided at the circumferential edge of the bearing part 110 to surround, so that the space formed by the surrounding part 160 and the bearing part 110 can accommodate the cleaning liquid for immersing the chip in the placing grooves 120, so that the cleaning is more thorough.
[0048] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 When the chip is taken out from the placing grooves 120, there will be some cleaning liquid in the placing grooves 120. In order to drain the cleaning liquid in the placing grooves 120, at least one liquid hole 140 is provided in the inner bottom wall of the placing grooves 120, and the liquid in the placing grooves 120 is drained through the liquid hole 140.
[0049] In this embodiment, when the chip needs to be cleaned, the chip is first placed in the placing grooves 120, and then the bearing part 110 is placed in the ultrasonic cleaning tank, and the depth of the cleaning liquid in the ultrasonic cleaning tank should be immersed in the chip.
[0050] The placing grooves 120 are provided with arc surfaces 150 at each corner, and the corners of two adjacent placing grooves 120 are connected by the arc surfaces 150.
[0051] Participate Figure 1 and Figure 2 In order to facilitate the cleaning liquid to quickly enter the inside of the placing grooves 120 and flow therein, the arc surfaces 150 are provided at each corner of the placing grooves 120, and the corners are connected by the arc surfaces 150, which reduces the resistance of the liquid and facilitates the flow and uniform distribution of the liquid.
[0052] In one embodiment, two adjacent placing grooves 120 are connected by the taking and placing grooves 130, so as to accelerate the liquid to enter the inside of each placing groove 120 for cleaning the chip.
[0053] The bearing part 110 is provided with an avoiding groove 180 penetrating therethrough.
[0054] Please refer to Figures 1 to 4 In order to not directly contact with the cleaning liquid in the ultrasonic cleaning tank, the bearing part 110 is taken and placed in the ultrasonic cleaning tank by the jig taking and placing device in the following text in cooperation with the avoiding groove 180, so as to reduce the harm to people.
[0055] The surrounding member 160 is arranged at the circumferential edge of the bearing member 110, and the bearing member 110 is provided with a support member 170 at the circumferential edge away from the plane on which the placing groove 120 is located.
[0056] Referring to Figure 3 and Figure 4 In order to prevent the bottom surface of the bearing member 110 from directly contacting the bottom surface of the ultrasonic cleaning tank, the support member 170 is arranged at the axial edge of the bottom surface of the bearing member 110, and the bearing member 110 is supported by the support member 170. Specifically, the support member 170 is a plurality of arc-shaped plates, and the curvature of the arc-shaped plates is adapted to the bearing member 110.
[0057] The embodiment of the present application discloses a placing jig taking and placing device 200, which comprises a handle 210, a transmission member 220, an abutting member 230, a screwing member 240 and an elastic member 250.
[0058] Specifically, the handle 210 has a guide hole arranged through in the axial direction, the transmission member 220 is slidingly arranged in the guide hole, the abutting member 230 is installed at the end of the transmission member 220, the screwing member 240 is installed at the end of the transmission member 220 away from the abutting member 230, the elastic member 250 is sleeved on the transmission member 220, one end of the elastic member 250 abuts against the handle 210, and the end of the elastic member 250 away from the handle 210 abuts against the screwing member 240.
[0059] Referring to Figure 5 The transmission member 220 is located in the axial guide hole of the handle 210, and the length of the transmission member 220 should be greater than the length of the handle 210. The end of the handle 210 is installed with an abutting member 230 which is adapted to the shape of the surrounding member 160, and the abutting member 230 can be deeply inserted into the surrounding member 160. The transmission member 220 is connected with the screwing member 240, and the screwing member 240 transmits the rotating force to the abutting member 230 through the transmission member 220, so that the abutting member 230 changes the angle.
[0060] It can be understood that when the carrier 110 needs to be placed into or taken out of the cleaning tank, the rotating member 240 drives the transmission member 220 to move downward against the elasticity of the elastic member 250 to move the abutting member 230, and then the abutting member 230 needs to pass through the surrounding member 160 to the lower side of the carrier 110, and then the rotating member 240 rotates to drive the abutting member 230 to rotate to change the angle of the abutting member 230, at this time, the carrier 110 is located between the upper surface of the abutting member 230 and the bottom end surface of the handle 210, and the abutting member 230 abuts against the lower surface of the carrier 110 under the elastic force of the elastic member 250, and the bottom end surface of the handle 210 abuts against the upper surface of the carrier 110, so as to fix the carrier 110, at this time, the cleaned carrier 110 with the chips can be taken out of the cleaning tank by lifting the handle 210 upward, or the carrier 110 with the chips can be placed into the cleaning tank by moving downward, and after taking out or placing, the abutting member 230 can be separated from the carrier 110 by reversing the above operation, that is, the abutting member 230 passes through the surrounding member 160 to the upper side of the carrier 110 to achieve separation.
[0061] In one embodiment, the length of the abutting member 230 is a1, the width is b1, and the height is h1, a1 is greater than b1, the length of the surrounding member 160 is a2, and the width is b2, a2>b2; the height of the supporting member 170 is h2, and a1<a2, b1<b2, a1>b2, and h1<h2 should be met, the purpose of a1<a2 and b1<b2 is to make the abutting member 230 more easily pass through the surrounding member 160, and h1<h2 is to make the abutting member 230 have a relatively sufficient rotating space to prevent collision during rotation.
[0062] For example, the length of a1 is 30 mm, the width of b1 is 10 mm, and the height of h1 is 6.5 mm, if the abutting member 230 needs to pass through the surrounding member 160, a2 should be greater than a1 and b2 should be greater than b1, so that the length of a2 is 32 mm and the width of b2 is 11.5 mm, and because the length and width of the surrounding member 160 are greater than the length and width of 320, the abutting member 230 can easily pass through the surrounding member 160. Further, when the carrier 110 is placed in the cleaning device, after the abutting member 230 passes through the surrounding member 160, in order to prevent the abutting member 230 from directly contacting the cleaning device and preventing the abutting member 230 from touching the bottom surface of the carrier 110, the height of the supporting member 170 needs to be greater than the thickness of the abutting member 230, that is, h2 is greater than h1, and the height of h can be 13 mm, at this time, the abutting member 230 can rotate in the space formed by the supporting member 170 without touching the bottom surface of the carrier 110 and the cleaning device. It should be noted that the parameters in the above description can be designed according to actual needs, and the specific values are not limited here.
[0063] The handle 210 includes a guide portion 211, and an abutment portion 212 is provided on the end face of the guide portion 211 facing the screwing member 240. The diameter of the abutment portion 212 is larger than that of the guide portion 211, and the guide hole axially penetrates the guide portion 211 and the abutment portion 212.
[0064] See Figures 5 to 7 As shown, in order to make it easy to hold, the handle 210 is configured as two parts: a guide part 211 and a stop part 212. The guide part 211 mainly serves as a guide and a stop part, which is used for the stop of the elastic element 250. Both the guide part 211 and the stop part 212 are cylindrical and coaxial. The guide hole axially penetrates the guide part 211 and the stop part 212.

Specifically, in order to enable the rotation force from the screwing member 240 to be transmitted to the transmission member 220, and then transmitted to the abutting member 230 through the transmission member 220, the screwing member 240 and the transmission member 220 are connected through the second recess 271 and the second protrusion 272, and the second protrusion 272 is inserted into the second recess 271 to achieve the connection. Specifically, the second protrusion 272 is arranged on the upper end surface of the transmission member 220, and the second recess 271 is arranged on the end surface of the screwing member 240.
