Detailed Embodiment

[0026] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0027] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0028] In the description of the present invention, the meaning of several is more than one, the meaning of multiple is more than two, and understandings such as greater than, less than, exceeding, etc. do not include the present number, and understandings such as above, below, within, etc. include the present number. If there is a description of first and second, it is only for the purpose of distinguishing technical features and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0029] In the description of the present invention, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0030] In the description of the present invention, the descriptions with reference to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples" mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0031] During the chip detection process, it is often necessary to use an image detection device to detect the shape of the chip. In this process, due to the change in the position of the chip, a driving structure is required to change the position of the detection device. In the related art, due to the change in the position of the chip, the driving structure needs to change the displacement of the detection device in at least two directions. For example, the front-back direction and the up-down direction, or for example, the left-right direction and the up-down direction. This makes it necessary to include two sets of driving devices in the driving structure, which not only increases the manufacturing and use costs, but also increases the load of the driving structure, making it unable to drive the detection device to move at high speed and affecting the detection rate.

[0032] In view of the above problems, the present invention discloses a detection structure 101, as Figures 1 to 3 shown. The detection structure 101 in this embodiment includes a detection member 102, a first moving block 103, a driving member 104, and a first track 105. The detection member 102 is used to absorb the light emitted when the chip is subjected to an electrical test, so as to determine whether the chip can work normally. A detection surface 206 is provided on the detection member 102, and the light enters the detection device through the detection surface 206, so as to form an image in the detection device. In this embodiment, the detection surface may not be the imaging surface, as long as the light entering the detection device passes through the detection surface. The output end of the driving member 104 is connected to the first moving block 103. The first moving block 103 can move along the first track 105, and the first track 105 is inclined relative to the detection surface. This enables the output end of the driving member 104 to drive the first moving block 103 to move downward to the left as Figure 2 shown when the output end of the driving member 104 extends outward, so that through the drive of the driving member 104, the detection member 102 can simultaneously complete a leftward movement and a downward movement. Similarly, when the output end of the driving member 104 retracts, the detection member 102 can complete a movement upward to the right through the first moving block 103.

[0033] In the embodiment of the above detection structure 101, only by the drive of one drive member 104, the detection member 102 can complete the movement in the left - right direction and the up - down direction. Compared with the prior art, the detection structure 101 in this embodiment can effectively save the number of drive devices while ensuring the drive of the detection member 102. At the same time, the detection structure 101 in this embodiment can also indirectly reduce the load of the drive structure and reduce the weight of the overall detection structure 101.

[0034] Specifically, as Figures 1 to 3 shown, the detection structure 101 further includes a positioning member 106 and a second moving block 205. The positioning member 106 is used to position the chip, and the second moving block 205 can move along the first track 105 to adjust the position of the positioning member 106. Specifically, since the first track 105 is inclined, when the second moving block 205 moves along the first track 105, the positioning member 106 can complete the movement, and the movement track of the positioning member 106 is parallel to the movement track of the detection member 102, (the positioning member can move to the lower left as Figure 2 shown, or move to the upper right as Figure 2 shown). Compared with the structure that needs to move on two perpendicular tracks in the related art, the structure in this embodiment simplifies the movement track of the positioning member 106, enabling the positioning member 106 to move quickly in response.

[0035] Specifically, as Figures 1 to 3 shown, the detection structure 101 further includes a connection block 107. The connection block 107 is connected to the output end of the drive member 104, and the connection block 107 is respectively connected to the first moving block 103 and the second moving block 205. This enables the first moving block 103 and the second moving block 205 to move synchronously by driving the connection block 107 by the drive member 104, and further enables the detection member 102 and the positioning member 106 to move synchronously. When the chip needs to be positioned, first, the drive member 104 adjusts the positioning member 106 so that the positioning member 106 can position the chip. During this process, the detection member 102 and the positioning member 106 move synchronously but do not work. When the positioning member 106 finishes working, the drive member 104 drives the positioning member 106 and the detection member 102 to move until the detection member 102 is directly above the chip and detects the chip.

[0036] In the above embodiment, a driving member 104 drives the detecting member 102 and the positioning member 106 to move together. Compared with the structure in the related art where different driving devices drive the detecting member 102 and the positioning member 106 to move respectively, the detecting structure 101 in this embodiment can save the number of driving devices. At the same time, through the connecting block 107, both the detecting member 102 and the positioning member 106 can move along the first track 105, which enables the driving member 104 to simultaneously move the positioning member 106 and the detecting member 102 to the lower left as shown in Figure 2 or to the upper right as shown in Figure 2 . Compared with the structure that requires several driving devices to drive the positioning member 106 and the detecting member 102 to move at different angles, the detecting structure 101 in this embodiment can effectively save the number of driving devices and reduce the weight of the overall device.

[0037] Specifically, as shown in Figures 1 to 3 , the detecting structure 101 further includes a first adjusting block 108 and a second adjusting block 109. The first adjusting block 108 is connected to the connecting block 107, and the detecting member 102 is connected to the second adjusting block 109. An adjusting slide rail 112 is provided on the first adjusting block 108 in the vertical direction as shown in Figure 1 . A plurality of positioning holes (not shown) are provided on the second adjusting block 109 in the vertical direction as shown in Figure 1 . Through fasteners, the positioning holes can be connected to the adjusting slide rail 112 (the fasteners press the second adjusting block 109 against the first adjusting block 108), so that the first adjusting block 108 positions the second adjusting block 109, and the position of the detecting member 102 relative to the connecting block 107 is fixed. When it is necessary to adjust the height of the detecting member 102 relative to the connecting block 107 according to the detection requirements, the fasteners can be loosened to connect the positioning holes to other positions of the adjusting slide rail 112, or connect the positioning holes at different positions to the same position of the adjusting slide rail 112, so as to change the distance between the detecting member 102 and the connecting block 107 in the vertical direction as shown in Figure 2 , thereby adjusting the distance between the detecting member 102 and the chip during the detection process.

[0038] Specifically, as shown in Figures 1 to 3 , the detecting structure 101 includes a base 110. The driving member 104, the detecting member 102, and the positioning member 106 are all connected to the base 110, and the base 110 supports the driving member 104, the detecting member 102, and the positioning member 106. An inclined surface 111 is provided on the base 110, and the first track 105 is arranged on the inclined surface 111, so that the first track 105 is inclined. When the connecting block 107 moves on the first track 105, the connecting block 107 can move to the lower left as shown in Figure 2 or to the upper right as shown in Figure 2The upper right movement shown drives the positioning member 106 and the detection member 102 to move downward to the left as shown in Figure 2 or to move upward to the right as shown in Figure 2 In this embodiment, due to the setting of the inclined surface 111, the connecting block 107 can move downward to the left as shown in Figure 2 or move upward to the right as shown in Figure 2 In other embodiments, if the inclination direction of the inclined surface 111 changes, the connecting block 107 can drive the positioning member 106 and the detection member 102 to move in other directions.

[0039] Specifically, as shown in Figures 1 to 3 , the detection structure 101 further includes a base 110, an output block 201, an identification structure 202, a first identification member 203, and a second identification member 204. The output block 201 is connected to the output end of the driving member 104. The output block 201 can also be connected to the connecting block 107 to drive the connecting block 107 to move, so that the positioning member 106 and the detection member 102 move. The identification structure 202 is connected to the output block 201. The first identification member 203 and the second identification member 204 are arranged along the direction of the first track 105, and the first identification member 203 is electrically connected to the driving member 104, and the second identification member 204 is electrically connected to the driving member 104. When the driving member 104 drives the output block 201 to move, the output block 201 drives the identification structure 202 to move. When the identification structure 202 moves to the first identification member 203, the driving member 104 stops moving to prevent the first moving block 103 and the second moving block 205 from disengaging from the first track 105. During the reset process of the positioning member 106 and the detection member 102, when the identification structure 202 moves to the second identification member 204, the driving member 104 stops moving, and the positioning member 106 and the detection member 102 complete the reset.

[0040] Specifically, as shown in Figures 1 to 3 , a second track 301 is further provided on the base 110, and the second track 301 is arranged parallel to the first track 105. The first identification member 203 and the second identification member 204 can both move relative to the second track 301 to meet the detection requirements of different chips. The above structure also has at least the following effects: Since the first track 105 and the second track 301 are arranged in parallel, no matter where the first identification member 203 and the second identification member 204 move on the second track 301, they can identify the identification structure 202 connected to the output block 201, ensuring the use safety of the positioning member 106 and the detection member 102 while ensuring the accuracy of the reset of the positioning member 106 and the detection member 102.

[0041] Specifically, in the above embodiments, the detection structure 101 further includes a lead screw 302. The lead screw 302 is connected to the output end of the driving member 104 through a coupling. The lead screw 302 can penetrate through the output block 201. The inner wall of the hole on the output block 201 through which the lead screw 302 passes is provided with internal threads. The working portion of the lead screw 302 with external threads can be connected to the internal threads of the output block 201. By rotating the lead screw 302, the driving member 104 can drive the output block 201 to move, thereby driving the positioning member 106 and the detection member 102 to move.

[0042] In the above embodiments, the detection member 102 may include a light-absorbing element, such as an integrating sphere, and the positioning member 106 may be a camera.

[0043] An embodiment of the present invention also discloses a chip detection mechanism. The chip detection mechanism includes a frame 402 and a probe. The base 110 of the detection structure 101 is connected to the frame 402. The chip detection mechanism further includes a moving platform 403 and a probe 401. The moving platform 403 can move relative to the frame 402 to adjust the position of the chip. The moving platform 403 is located below the detection structure 101. After the position of the chip is identified by the positioning member 106, the detection member 102 is adjusted by driving of the driving member 104 so that the detection member 102 is located above the moving platform 403. At this time, the probe 401 is connected to the frame 402 to perform electrical detection on the chip. The detection member 102 collects the light emitted by the chip and determines whether the chip can emit light normally. In the detection structure 101, only one driving member 104 can be used to move the detection member 102 and the positioning member 106 together. This not only reduces the overall weight of the chip detection mechanism but also can reduce the production cost of the chip detection mechanism.

[0044] The above has described in detail the embodiments of the present invention with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
