Description
Technical Field
[0001] The present invention relates to the technical field of chip processing, and in particular to a chip probe card alignment adjustment device. Background Art
[0002] When a chip and a probe card are processed, they often need to be assembled. The chip and the probe card often need to be aligned before assembly. In the prior art Chinese patent CN212514886U, the relative position between the chip and the probe card is adjusted directly by manual adjustment, and the position recognition is carried out manually. Due to the error of manual operation, the position accuracy of such a recognition method is low, resulting in low accuracy in the subsequent assembly of the chip and the probe card. Moreover, the subsequent assembly is all carried out manually, and its accuracy is relatively low, which cannot meet the existing production requirements.
[0003] Therefore, it is necessary to provide a chip probe card alignment adjustment device. Summary of the Invention
[0004] Aiming at the problems mentioned in the background art, the purpose of the present invention is to provide a chip probe card alignment adjustment device that can automatically align and adjust between the chip and the probe card, so as to solve the problems mentioned in the background art.
[0005] To achieve the above object, the chip probe card alignment adjustment device provided by the present invention includes a frame, a needle card position adjustment mechanism, and a chip probe card automatic detection and alignment mechanism. The chip probe card automatic detection and alignment mechanism includes an image recognition component, an upper carrier table, and a bottom carrier component installed on the frame. The bottom carrier component is used to carry and position the first workpiece. The upper carrier table is located above the bottom carrier component and is used to carry the second workpiece. The needle card position adjustment mechanism has a position adjustment mechanism, a carrier, and a movable disassembly and assembly table installed on the frame. An identification hole for the image recognition component to recognize is provided on the upper carrier table. The disassembly and assembly table moves the carrier to the upper carrier table so that the second workpiece on the carrier is carried at the identification hole. The image recognition component is located above the upper carrier table. The image recognition component recognizes the position of the first workpiece on the bottom carrier component through the identification hole. When the second workpiece is carried at the identification hole through the movement of the disassembly and assembly table, the image recognition component recognizes the position of the second workpiece on the upper carrier table. The image recognition component records the positions of the first workpiece and the second workpiece and transmits them to the position adjustment mechanism. The disassembly and assembly table moves the carrier on the upper carrier table away and adjusts the position of the carrier through the position adjustment mechanism. The disassembly and assembly table moves the adjusted carrier to the upper carrier table again. The final relative position between the second workpiece on the carrier and the first workpiece on the bottom carrier component is determined by disassembling the carrier from the disassembly and assembly table to the upper carrier table.
[0006] Preferably, the needle card position adjustment mechanism includes a lifting device, a rotating device, a Y-axis moving device, an X-axis moving device, a disassembly and assembly table, a carrier, and a locking component. The lifting device is installed on the frame. The rotating device is installed at the output end of the lifting device. The rotating device is lifted under the drive of the lifting device. The Y-axis moving device is installed at the output end of the rotating device. The Y-axis moving device rotates under the drive of the rotating device.

The X-axis moving device moves along the Y-axis direction of the frame under the drive of the Y-axis moving device. The disassembly and assembly table is installed at the output end of the X-axis moving device. The disassembly and assembly table moves along the X-axis direction of the frame under the drive of the X-axis moving device. The disassembly and assembly table is recessed downward to form a trough structure with an upward opening and an outward opening. The carrier is slidably arranged in the trough structure. The needle card position adjustment mechanism further includes a locking component. The locking component is used to detachably install the carrier in the trough structure.
[0007] Preferably, the bottom carrier assembly includes a fixing frame, a second lifting driving device, a lifting carrier seat, a fixture and a pressure detection device.

[0008] Specifically, the fixture includes a first elastic clamping member and a second elastic clamping member. A first positioning groove and a second positioning groove with upward openings are formed in the lifting carrier seat. The first positioning groove and the second positioning groove are perpendicular to each other and communicate with each other. The intersection of the first positioning groove and the second positioning groove communicates to form two mutually perpendicular abutting walls; the first elastic clamping member has a first elastic pressing block which is slidably arranged in the first positioning groove, the second elastic clamping member has a second elastic pressing block which is slidably arranged in the second positioning groove, and the first elastic pressing block, the second elastic pressing block, the first positioning groove and the second positioning groove can jointly clamp the four edges of the first workpiece.
[0009] Specifically, each of the first elastic clamping member and the second elastic clamping member includes a guiding member, a pressing block body and an elastic member. The guiding member is installed on the fixing frame, the pressing block body is installed on the lifting carrier seat, the pressing block body is connected to the lifting carrier seat through the elastic member, and due to the elastic member, the pressing block body always has a tendency to approach the lifting carrier seat. The pressing block body extends outwards to form the first elastic pressing block or the second elastic pressing block. The guiding member has a guiding inclined surface, and the pressing block body has a guiding column slidably arranged on the guiding inclined surface. Due to the guiding column being slidably arranged on the guiding inclined surface, the pressing block body moves away from the lifting carrier seat against the elastic force of the elastic member or moves towards the lifting carrier seat under the elastic action of the elastic member.
[0010] Specifically, the pressing block body is slidably arranged on the lifting carrier seat. The lifting carrier seat is provided with connecting ears corresponding to the elastic member.

The bottom carrier component is used to carry and position the first workpiece. The upper carrier table is located above the bottom carrier component and is used to carry the second workpiece. The needle card position adjustment mechanism has a position adjustment mechanism, a carrier, and a movable disassembly and assembly table mounted on the frame. The disassembly and assembly table moves the carrier to the upper carrier table so that the second workpiece on the carrier is carried at the recognition hole. It can be understood that the movement of the disassembly and assembly table can avoid blocking the first workpiece located below when not in recognition and achieve the docking between the needle card position adjustment mechanism and the chip probe card automatic detection and alignment mechanism. The upper carrier table is provided with a recognition hole for the image recognition component to recognize. The image recognition component is located above the upper carrier table. The image recognition component recognizes the position of the first workpiece on the bottom carrier component through the recognition hole. When the second workpiece is carried at the recognition hole through the movement of the disassembly and assembly table, the image recognition component recognizes the position of the second workpiece on the upper carrier table. By means of the image recognition component, the positions of the first workpiece and the second workpiece are recorded and transmitted to the position adjustment mechanism. The disassembly and assembly table moves to remove the carrier on the upper carrier table and adjusts the position of the carrier through the position adjustment mechanism. The disassembly and assembly table moves to move the adjusted carrier to the upper carrier table again. By removing the carrier from the disassembly and assembly table to the upper carrier table, the final relative position between the second workpiece on the carrier and the first workpiece on the bottom carrier component is determined. In other words, the first step of the chip probe card alignment adjustment device of the present invention is to respectively recognize the positions of the first workpiece and the second workpiece, obtain the relative position between the two by comparison, then adjust the position of the second workpiece through the needle card position adjustment mechanism, and after the adjustment is completed, determine the position of the second workpiece to indirectly achieve the purpose of adjusting the relative position between the first workpiece and the second workpiece. Subsequently, the aligned first workpiece and second workpiece are removed by an external device and then assembled, which can achieve automatic alignment and post-alignment adjustment, meeting the requirements for position accuracy in existing production.

[0029] Reference Figures 1 to 10, A chip probe card alignment adjustment device 100, which includes a frame 11, a needle card position adjustment mechanism 20, and a chip probe card automatic detection and alignment mechanism 10. The chip probe card automatic detection and alignment mechanism 10 includes an image recognition component 12, an upper carrier table 13, and a bottom carrier component 14 installed on the frame 11. The bottom carrier component 14 is used to carry and position the first workpiece. The upper carrier table 13 is located above the bottom carrier component 14 and is used to carry the second workpiece. The needle card position adjustment mechanism 20 has a position adjustment mechanism, a carrier 27, and a movable disassembly and assembly table 26 installed on the frame 11. The disassembly and assembly table 26 moves the carrier 27 to the upper carrier table 13 so that the second workpiece on the carrier 27 is carried at the recognition hole 131. It can be understood that the movement of the disassembly and assembly table 26 can avoid blocking the first workpiece located below when not in recognition and achieve the docking between the needle card position adjustment mechanism 20 and the chip probe card automatic detection and alignment mechanism 10. A recognition hole 131 for the image recognition component 12 to recognize is opened on the upper carrier table 13. The image recognition component 12 is located above the upper carrier table 13. The image recognition component 12 recognizes the position of the first workpiece on the bottom carrier component 14 through the recognition hole 131. When the second workpiece is carried at the recognition hole 131 through the movement of the disassembly and assembly table 26, the image recognition component 12 recognizes the position of the second workpiece on the upper carrier table 13. The image recognition component 12 records the positions of the first workpiece and the second workpiece and transmits them to the needle card position adjustment mechanism 20. The disassembly and assembly table 26 moves to remove the carrier on the upper carrier table 13 and adjusts the position of the carrier 27 through the position adjustment mechanism. The disassembly and assembly table 26 moves the adjusted carrier 27 to the upper carrier table 13 again. By detaching the carrier 27 from the disassembly and assembly table 26 to the upper carrier table 13, the final relative position between the second workpiece on the carrier 27 and the first workpiece on the bottom carrier component 14 is determined. In other words, the first step of the chip probe card alignment adjustment device 100 of the present invention is to respectively recognize the positions of the first workpiece and the second workpiece, obtain the relative position between the two through comparison, then adjust the position of the second workpiece through the needle card position adjustment mechanism 20, and after the adjustment is completed, determine the position of the second workpiece to indirectly achieve the purpose of adjusting the relative position between the first workpiece and the second workpiece. Subsequently, the aligned first workpiece and second workpiece are removed by an external device and then subsequent assembly is realized, which can achieve automatic alignment and adjustment after alignment, meeting the requirements for position accuracy in existing production.

[0032] Reference Figures 4 to 5 , the bottom carrier assembly 14 includes a fixing frame 141, a second lifting drive device 142, a lifting carrier seat 1421, a clamp 143 and a pressure detection device 144. The fixing frame 141 is installed on the frame 11, the second lifting drive device 142 is installed on the frame 11, the lifting carrier seat 1421 is installed at the output end of the second lifting drive device 142, and the lifting carrier seat 1421 rises and falls under the drive of the second lifting drive device 142 and has an extended position and a retracted position through lifting. The pressure detection device 144 is built into the lifting carrier seat 1421. The clamp 143 is installed between the fixing frame 141 and the lifting carrier seat 1421. When the lifting carrier seat 1421 descends and the lifting carrier seat 1421 is in the retracted position, the clamp 143 descends and releases the first workpiece on the lifting carrier seat 1421 through lateral sliding. When the lifting carrier seat 1421 rises and the lifting carrier seat 1421 is in the extended position, the clamp 143 rises and clamps the first workpiece on the lifting carrier seat 1421 through lateral sliding. Specifically, the clamp 143 includes a first elastic clamping member 1431 and a second elastic clamping member 1432. The lifting carrier seat 1421 is provided with a first positioning groove 14212 and a second positioning groove 14211 with upward openings. The first positioning groove 14212 and the second positioning groove 14211 are perpendicular to each other and communicate with each other. The first positioning groove 14212 and the second positioning groove 14211 are open groove structures. The intersection of the first positioning groove 14212 and the second positioning groove 14211 communicates, thus forming two mutually perpendicular abutting walls. The first elastic clamping member 1431 has a first elastic pressing block 14311, and the first elastic pressing block 14311 is slidably arranged in the first positioning groove 14212. The second elastic clamping member 1432 has a second elastic pressing block 14321, and the second elastic pressing block 14321 is slidably arranged in the second positioning groove 14211.

The pressure block body 1434 is connected to the lifting carrier seat 1421 through the elastic member 1435. Due to the elastic member 1435, the pressure block body 1434 always has a tendency to approach the lifting carrier seat 1421. The pressure block body 1434 extends outward to form a first elastic pressure block 14311, and another pressure block body 1434 extends outward to form a second elastic pressure block 14321. The guide member 1433 has a guide inclined surface 14331, and the pressure block body 1434 has a guide post 1434a that slides on the guide inclined surface 14331. Due to the guide post 1434a sliding on the guide inclined surface 14331, the pressure block body 1434 moves away from the lifting carrier seat 1421 against the elastic force of the elastic member 1435 or moves toward the lifting carrier seat 1421 under the elastic action of the elastic member 1435. Preferably, the elastic member 1435 is a compression spring, but it is not limited thereto.

The carrier 27 is slidably arranged in the groove structure 261 along the X-axis direction. The locking component 28 is used to detachably install the carrier 27 in the groove structure 261. Due to the setting of the locking component 28, the locking component 28 can achieve the detachable connection between the carrier 27 and the groove structure 261, that is, when the position is adjusted by using the lifting device 22, the rotating device 23, the Y-axis moving device 24 and the X-axis moving device 25, etc., it is convenient to detach the whole carrier 27 and directly assemble it, which not only realizes the automatic position adjustment, but also improves the position accuracy of the assembly.

[0043] The following combines Figures 1 to 10 , and details the usage method of the chip probe card alignment adjustment device of the present invention:
[0044] The image recognition component 12 recognizes the position of the first workpiece on the bottom carrier component through the recognition hole 131. At this time, the second workpiece avoids the image recognition component at the recognition hole through the movement of the disassembly and assembly table. After the position of the first workpiece is recognized, when the second workpiece is carried at the recognition hole through the movement of the disassembly and assembly table, the image recognition component recognizes the position of the second workpiece on the upper carrier table. By comparing the relative positions of the first workpiece and the second workpiece, it is judged whether position adjustment is needed and the specific situation of position adjustment, and the corresponding position adjustment signal is transmitted to the needle card position adjustment mechanism. The second workpiece moves the carrier to the needle card position adjustment mechanism through the movement of the disassembly and assembly table. The rotating device 23 rises and falls under the drive of the lifting device 22, so as to adjust the position of the carrier 27 in the height direction. The Y-axis moving device 24 rotates under the drive of the rotating device 23, so as to adjust the position of the carrier 27 in the rotation direction. The X-axis moving device 25 moves along the Y-axis direction of the frame 21 under the drive of the Y-axis moving device 24, so as to adjust the position of the carrier 27 in the Y-axis direction. The disassembly and assembly table 26 moves along the X-axis direction of the frame 21 under the drive of the X-axis moving device 25, so as to adjust the position of the carrier 27 in the X-axis direction. After adjusting the position by using the lifting device 22, the rotating device 23, the Y-axis moving device 24 and the X-axis moving device 25, etc., the second workpiece is carried at the recognition hole again through the movement of the disassembly and assembly table. The entire carrier 27 is disassembled and directly assembled at the corresponding position of the chip by unlocking the locking component 28. At this time, the relative positions of the chip and the probe card are determined and conveyed to the next working station through an external device.

The needle card position adjustment mechanism has a position adjustment mechanism, a carrier, and a movable disassembly and assembly table installed on the frame. The disassembly and assembly table moves the carrier to the upper carrier table so that the second workpiece on the carrier is carried at the recognition hole. It can be understood that the movement of the disassembly and assembly table can avoid blocking the first workpiece located below when not in recognition and achieve the docking between the needle card position adjustment mechanism and the automatic detection and alignment mechanism for a chip probe card. A recognition hole for the image recognition component to recognize is provided on the upper carrier table. The image recognition component is located above the upper carrier table. The image recognition component recognizes the position of the first workpiece on the bottom carrier component through the recognition hole. When the second workpiece is carried at the recognition hole through the movement of the disassembly and assembly table, the image recognition component recognizes the position of the second workpiece on the upper carrier table. By means of the image recognition component, the positions of the first workpiece and the second workpiece are recorded and sent to the position adjustment mechanism. The disassembly and assembly table moves to remove the carrier on the upper carrier table and adjusts the position of the carrier through the position adjustment mechanism. The disassembly and assembly table moves to move the adjusted carrier to the upper carrier table again. By detaching the carrier from the disassembly and assembly table to the upper carrier table, the final relative position between the second workpiece on the carrier and the first workpiece on the bottom carrier component is determined. In other words, the first step of the chip probe card alignment adjustment device of the present invention is to separately recognize the positions of the first workpiece and the second workpiece and obtain the relative position between the two through comparison, then adjust the position of the second workpiece through the needle card position adjustment mechanism, and after the adjustment is completed, determine the position of the second workpiece to indirectly achieve the purpose of adjusting the relative position between the first workpiece and the second workpiece. Subsequently, the aligned first workpiece and second workpiece are removed by an external device and then assembled, which can achieve automatic alignment and post-alignment adjustment, meeting the requirements for position accuracy in existing production.
