Description

Technical Field

[0001] The invention relates to the field of chip testing, and in particular to a three-axis independently fixed waffle box structure device. Background Art

[0002] The chip test switch is a special equipment for testing chip functions and performance. During the test, the chip test switch applies input signals to the chip to be tested, thereby obtaining relevant output signals, and compares them with expected values, thereby judging the electrical performance of the chip to be tested and the effectiveness of the product functions; in the detection link, the chip test switch transmits the comparison results of the output signal and the expected value to the probe station and the sorting machine respectively. Multiple new chips to be tested are installed in the same waffle box and fixed in the fixed module area of ​​the chip test switch. The chip test switch uses a suction nozzle to suck the chips to be tested from the waffle box in turn, contact them with the probe and test them. After receiving the test results, the probe will make selections and classifications. In this working process, the nozzle must ensure that the chip to be tested does not shake when sucking the chip to be tested, so the stability of the fixing device of the waffle box is extremely high.

[0003] The waffle box is mainly composed of three parts: the upper cover, the chip holder and the card clip. It is a box used to package chips and is made of anti-static material. Usually, a layer of dust-free paper is added to the chip holder for isolation and packaging to make it have a better protective effect. Generally, the bottom of the waffle box is fixed by vacuum adsorption, but when the bottom of the waffle box is uneven, the vacuum suction force is usually difficult to meet the requirements of stability.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The thickness of a general waffle box is only 2.2mm, and the height of the reinforcement ribs is 0.05mm, and the spacing between the reinforcement ribs is 0.3mm. This reinforcement rib design is to prevent the waffle box from shrinking and deforming when it is cold during the production process, that is, to prevent the physical phenomenon of thermal expansion and contraction during the injection molding process. The current waffle box fixing device usually uses a single suction cup vacuum suction method to ensure the stability of the waffle box, but from the appearance design of the waffle box, the surface adsorbed by the vacuum suction cup is not a smooth plane, but an uneven surface with many cross-ribs. Therefore, in actual use, vacuum suction alone cannot ensure a stable clamping.

[0025] The existing vacuum clamping waffle box carrier cannot take into account both the stability of the waffle box and the convenience in the actual production process. In order to effectively solve the problem of the chip test switching equipment firmly clamping the waffle box, the present invention provides a three-axis independent fixing waffle box structure device, such as Figure 1 , Figure 2 As shown, it includes a circular base 101, a left XY axis fixing structure, a right XY axis fixing structure and a Z axis vacuum adsorption structure; a circular groove 102 is provided on the upper surface of the circular base 101; a through suction head hole is opened at the upper part of the circular groove 102, and a bottom groove 103 is provided in the middle and lower part of the circular groove 102; the left XY axis fixing structure and the right XY axis fixing structure are arranged side by side in the bottom groove 103; the Z axis vacuum adsorption structure is located on the lower surface of the circular base.

[0026] Specifically, Figure 3 , Figure 6 As shown, the left XY axis fixing structure includes a first straight plate 211, a first X-axis moving block 212 and a first Y-axis moving block 213; a first waffle box placing area block 214 is provided on the upper surface of the first straight plate 211, and a through first suction cup hole 215 is provided in the middle of the first waffle box placing area block 214; a first X-axis moving channel 216 is opened outwardly on the left side of the first suction cup hole 215, and a first Y-axis moving channel 217 is provided outwardly on the lower side of the first suction cup hole 215; the first X-axis moving block 212 and the first Y-axis moving block 213 are slidably disposed in the first X-axis moving channel 216 and the first Y-axis moving channel 217 respectively;

[0027] The right XY axis fixing structure includes a second straight plate 221, a second X-axis moving block 222 and a second Y-axis moving block 223; a second waffle box placing area block 224 is provided on the upper surface of the second straight plate 221, and a through second suction cup hole 225 is provided in the middle of the second waffle box placing area block 224; a second X-axis moving channel is opened outward on the right side of the second suction cup hole 225, and a second Y-axis moving channel is provided outward on the lower side of the second suction cup hole 225; the second X-axis moving block 222 and the second Y-axis moving block 223 are respectively slidably arranged in the second X-axis moving channel and the second Y-axis moving channel.

[0028] Specifically, Figure 4 As shown, a corner block 218 is protruded from each side of the top of the upper surface of the first straight plate 211, and each corner block 218 has a through screw hole; and a long block 219 is protruded from the bottom of the upper surface of the first straight plate 211, and each of the two ends of the long block 219 has a through screw hole. The second straight plate is similar to the first straight plate, and a corner block is protruded from each side of the top of the upper surface of the second straight plate, and each of the corner blocks has a through screw hole; and a long block is protruded from the bottom of the upper surface of the second straight plate, and each of the two ends of the long block has a through screw hole.

[0029] The first straight plate and the second straight plate are both fixed on the circular base by screwing through four through screw holes.

[0030] Specifically, the first X-axis moving block and the second X-axis moving block have the same structure, and the first Y-axis moving block and the second Y-axis moving block have the same structure.

[0031] Specifically, taking the left XY axis fixed structure as an example, Figure 4 As shown, the first X-axis moving channel opened in the left XY-axis fixed structure includes two parts: a first lower straight plate channel and a first upper waffle box placement area block channel, and the width of the first lower straight plate channel is greater than the width of the first upper waffle box placement area block channel, that is, Figure 4 As a reference, when viewed from the left, the first X-axis moving channel is shaped like a "convex" character. To ensure that the first X-axis moving block can fit and move tightly in the first X-axis moving channel, the structure of the first X-axis moving block is the same as that of the first X-axis moving channel. Specifically, the first X-axis moving block is composed of a convex plate and a first limiting screw; the shape of the convex plate is the same as that of the first X-axis moving channel, and the convex plate is an integrated structure composed of a first upper rectangular block and a first lower rectangular block, such as Figure 5 As shown, the length and width of the first upper rectangular block are smaller than those of the first lower rectangular block, and the left sides of the first upper rectangular block and the first lower rectangular block are aligned; the left side of the convex plate faces the suction cup hole, and an arc groove is opened in the middle of the left side of the convex plate; a first threaded hole is provided inside the convex plate, and the first limiting screw is connected to the first threaded hole.

[0032] At the same time, if Figure 4 , Figure 5 It can be seen that the first Y-axis moving channel opened in the left XY-axis fixed structure includes two parts: the second lower straight plate channel and the second upper waffle box placement area block channel, and the width of the second lower straight plate channel is equal to the width of the second upper waffle box placement area block channel. In order to ensure that the first Y-axis moving block can move closely in the first Y-axis moving channel, the structure of the first Y-axis moving block is the same as the first Y-axis moving channel. Specifically, the first Y-axis moving block is composed of an L-shaped plate and a second limiting screw; the shape of the L-shaped plate is the same as that of the first X-axis moving channel, and the L-shaped plate is an integrated structure composed of the second upper rectangular block and the second lower rectangular block, such as Figure 5 As shown, the length and width of the second upper rectangular block are equal to those of the second lower rectangular block, and the second upper rectangular block is aligned with the left side of the second lower rectangular block; the left side of the L-shaped plate faces the suction cup hole, and an arc groove is opened in the middle of the left side of the L-shaped plate; a second threaded hole is provided inside the L-shaped plate, and the second limiting screw is connected to the second threaded hole.

[0033] The right XY-axis fixed structure and the left XY-axis fixed structure have the same settings except for the different settings of the X-axis moving block; that is, the second X-axis moving channel, the second Y-axis moving channel, the second X-axis moving block and the second Y-axis moving block of the right XY-axis fixed structure are the same as the first X-axis moving channel, the first Y-axis moving channel, the first X-axis moving block and the first Y-axis moving block of the left XY-axis fixed structure.

[0034] Specifically, the left XY axis fixed structure is still used for explanation. Figure 1 In the overall structure shown, a suction cup is fixed in the first suction cup hole, and the first limiting screw of the first X-axis moving block and the second limiting screw of the first Y-axis moving block both abut against the suction cup, and the position remains fixed; Figure 8 As shown, the size of the first waffle box placement area block is smaller than the size of the waffle box, so the first waffle box placement area block is wrapped in the waffle box chassis, the first upper rectangular block of the convex plate is located in the waffle box chassis and clamps the edge of the waffle box, and similarly the second upper rectangular block of the L-shaped plate is located in the waffle box chassis and also clamps the edge of the waffle box, when the first limiting screw or the second limiting screw is rotated, the convex plate or the L-shaped plate moves in the channel with the rotation, and the first waffle box placement area block, the first X-axis moving block and the first Y-axis moving block apply force to the four sides of the waffle box to achieve limited fixation of the waffle box in the X and Y axis directions.

[0035] Specifically, Figure 7As shown, the Z-axis vacuum adsorption structure includes a connecting structure and an adsorption structure; the adsorption structure includes two adsorption modules; the connecting structure includes an elbow-type air pipe quick connector 301, a manifold Y-type air pipe quick connector 302, a connecting pipe Y-type air pipe quick connector 303, a straight air pipe quick connector 304 and a connecting hose 305; the connecting pipe Y-type air pipe quick connector 303 is connected to a manifold Y-type air pipe quick connector 302 and two straight air pipe quick connectors 304 through a connecting hose 305; the manifold Y-type air pipe quick connector 302 is fixedly connected to the elbow-type air pipe quick connector 301, and the elbow-type air pipe quick connector 301 is fixed on the circular base through the suction head hole; each straight air pipe quick connector 304 is connected to an adsorption module.

[0036] Specifically, the adsorption module includes a suction cup base 401, a connector hole is provided on the side of the suction cup base 401 for connecting a straight air pipe quick connector, and a vacuum suction cup 402 is fixed on the upper surface of the suction cup base 401 for adsorbing the waffle box. The suction cup base 401 is fixed on the lower surface of the circular base.

[0037] Specifically, Figure 1 , Figure 2 It can be seen that the two vacuum suction cups are respectively arranged at the suction cup holes of the two straight plates.

[0038] In the present invention, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "rotation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
