Technical Field

[0001] The utility model relates to the field of chip sorting, in particular to chip sorting equipment for integrated circuit production. Background Art

[0002] An integrated chip is a chip manufactured by first integrating transistors into specialized cores, which are then integrated into a single chip using semiconductor technology based on application requirements. A core is a prefabricated, functionally specific wafer that can be assembled and integrated, also known as a "chiplet." Its functions can include a general-purpose processor, memory, graphics processor, encryption engine, network interface, and more.

[0003] During the integrated circuit chip sorting process, a suction mechanism is typically used to perform material suction. Patent publication number CN217376407U discloses a suction mechanism for an integrated circuit chip translation sorter. The mechanism comprises a first linear module and a second linear module that can move forward and backward along the first linear module. The second linear module is provided with a suction mechanism that can move left and right along the second linear module. The suction mechanism includes a suction frame equipped with multiple liftable and adjustable-pitch suction nozzles for sucking up and transporting chips to a testing position. This utility model features a reasonable design, a simple structure, ease of use, time-saving and labor-saving features, and improved work efficiency, offering broad application prospects.

[0004] However, the suction nozzle of the above-mentioned suction mechanism is fixed by multiple bolts. After wear, the entire suction nozzle needs to be disassembled and replaced with tools, and the disassembly and assembly efficiency is low, which in turn affects the subsequent chip sorting efficiency. Therefore, to address the above problem, a chip selection device for integrated circuit production is proposed. Utility Model Content

[0005] In order to make up for the shortcomings of the existing technology and solve the problem that the suction nozzle of the existing suction mechanism is fixed by multiple bolts, and the entire suction nozzle needs to be disassembled and replaced with tools after wear, which has low disassembly and assembly efficiency and thus affects the subsequent chip sorting efficiency, the utility model proposes a chip selection device for integrated circuit production.

[0006] The technical solution adopted by the present invention to solve its technical problems is: the chip selection equipment for integrated circuit production described in the present invention includes a lifting device, a suction head, a suction tube and a rubber head. The lifting device is fixedly connected to the mobile module on the frame, the suction head is fixedly installed on the bottom telescopic end of the lifting device, the suction tube is fixedly installed on the bottom of the suction head, and a mounting assembly is provided at the bottom of the suction tube. The rubber head is detachably mounted on the bottom of the suction tube through the mounting assembly, and the suction head and the suction tube are driven down by the lifting device to absorb the integrated circuit chip. The rubber head is provided to avoid damage to the surface of the integrated circuit chip.

[0007] Preferably, the mounting assembly includes a fixing block, which is provided with four fixing blocks and is symmetrically fixedly connected around the bottom end of the suction tube. A groove is provided in the middle of the end of the fixing block away from the suction tube, and a limit block is movably installed in the middle of the groove. A through-type long groove is provided in the middle of the limit block, and a mounting shaft is movably installed inside the long groove. The mounting shaft is perpendicular to the length direction of the long groove, and both ends of the mounting shaft extend outward and are rotatably inserted into the mounting holes opened on the side walls of both sides of the groove. A sliding rod is fixedly installed in the middle position in the length direction of the long groove, and a through hole is provided in the middle of the mounting shaft. The sliding rod passes through the through hole, and a spring is sleeved on the sliding rod. By setting the mounting assembly, it is convenient to install the rubber head at the bottom of the suction tube, and when the bottom of the rubber head is worn, it is convenient to quickly disassemble and replace the rubber head.

[0008] Preferably, the two ends of the mounting shaft respectively pass through the mounting hole and extend to the outside of the fixed block, and the two ends of the mounting shaft are respectively fixedly installed with torsion springs, and the two ends of the torsion spring are decomposed and fixedly connected to the end of the mounting shaft and the outer wall of the mounting block. By setting the torsion spring, the limit block is flipped inward, thereby facilitating the clamping of the rubber head.

[0009] Preferably, the rubber head is integrally formed by a clamping end, a connecting section and an abutting end, and the clamping end is arranged between the limiting block and the bottom end of the suction tube to facilitate clamping the rubber head to the inner side of the limiting block.

[0010] Preferably, one end of the limit block extends toward the center of the suction tube to the outside of the groove, and the end of the limit block located outside the groove is set to be inclined to facilitate the rubber head to be inserted into the inside of the limit block from the outside.

[0011] Preferably, a tightening assembly is provided on the inner side of the bottom end of the suction tube, and the tightening assembly includes a tube body, and the tube body is slidably arranged inside the bottom end of the suction tube, and the bottom end of the tube body is fixedly connected to an abutment plate, and the abutment plate is arranged on the outer side of the bottom end of the suction tube, and a sinking groove is opened in the inner wall of the bottom end of the suction tube, and a spring 2 is fixedly installed inside the sinking groove, and the bottom end of the spring 2 is fixedly connected to the inner wall of the abutment plate. By setting the abutment assembly, the rubber head is stably clamped on the inner side of the limit block, and the air tightness between the rubber head and the suction tube is increased.

[0012] Preferably, a pad is fixedly connected to one side of the middle of the suction pipe inside the groove to prevent the limiting block from flipping inward, so that the limiting block remains in a position perpendicular to the fixed block.

[0013] The utility model is beneficial in that:

[0014] When the clamping end completely passes the end of the limit block, the limit block is pushed back by the spring, thereby making the end of the limit block abut against the side wall of the connecting section on the rubber head, thereby preventing the rubber head from falling off, and realizing quick installation of the rubber head, simple operation and improved replacement efficiency.

[0015] 2. The utility model makes the rubber head more stable during installation through the abutment assembly. During use, when the clamping end passes through the limit block, the end face of the clamping end contacts the abutment plate, and the second spring is compressed. When the clamping end completely passes through the limit block, the second spring and the abutment plate cooperate to push the clamping end tightly against the limit block, making it easy to stably clamp the rubber head on the inner side of the limit block, and increase the air tightness between the rubber head and the suction tube, making it easier to absorb the integrated circuit chip.

[0024] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] See also Figure 1-6 As shown, a chip selection equipment for integrated circuit production includes a lifting device 1, a suction head 2, a suction tube 3 and a rubber head 5. The lifting device 1 is fixedly connected to the mobile module on the frame, the suction head 2 is fixedly installed on the bottom telescopic end of the lifting device 1, and the suction tube 3 is fixedly installed on the bottom of the suction head 2. The bottom of the suction tube 3 is provided with a mounting assembly 4, and the rubber head 5 is detachably mounted on the bottom of the suction tube 3 through the mounting assembly 4; when working, the lifting device 1 is moved to the top of the integrated circuit chip through the mobile module on the frame, and the suction head 2, the suction tube 3 and the rubber head 5 are controlled to descend through the lifting device 1, so that the rubber head 5 abuts against the top of the integrated circuit chip, and the suction head 2 is connected to the external exhaust device, and the suction device generates suction to adsorb the integrated circuit chip to the bottom of the rubber head 5, so that the integrated circuit chip is sucked and processed, which is convenient for selecting the required integrated circuit chip.

[0027] The mounting assembly 4 includes a fixing block 41, which is provided with four fixing blocks 41 and is symmetrically fixedly connected to the four sides of the bottom end of the suction pipe 3. A groove 42 is provided in the middle of the end of the fixing block 41 away from the suction pipe 3. A limit block 43 is movably installed in the middle of the groove 42. A through-type long groove 45 is provided in the middle of the limit block 43. A mounting shaft 44 is movably installed inside the long groove 45. The mounting shaft 44 is perpendicular to the length direction of the long groove 45. Both ends of the mounting shaft 44 extend outward and are rotatably inserted into the mounting holes provided on the side walls of the groove 42 on both sides. A sliding rod 47 is fixedly installed in the middle position of the length direction of the long groove 45. A through hole 46 is provided in the middle of the mounting shaft 44. The sliding rod 47 passes through the through hole 46. A spring 48 is sleeved on the sliding rod 47. When working, when the rubber head 5 at the bottom of the suction pipe 3 is worn, it is directly moved to When the rubber head 5 is pulled out, the clamping end 51 of the rubber head 5 drives the limit block 43 to flip outward with the installation shaft 44 as the center, so that the rubber head 5 can be removed. At the same time, the limit block 43 can drive the installation shaft 44 to rotate at the same time through the internal sliding rod 47, at this time, the torsion spring 49 starts to accumulate force. When the rubber head 5 is removed, the limit block 43 is driven to return to its original position through the torsion spring 49. Then, the clamping end 51 on the new rubber head 5 is inserted from the middle position of the installation assembly 4. The edge of the clamping end 51 first contacts the inclined surface of the end of the limit block 43, thereby forcing the limit block 43 to move outward, and the spring 1 48 is compressed. When the clamping end 51 completely passes the end of the limit block 43, the spring 1 48 pushes the limit block 43 to return to its original position, thereby making the end of the limit block 43 abut against the side wall of the connecting section 52 on the rubber head 5, thereby preventing the rubber head 5 from falling off, and thus realizing the rapid installation of the rubber head 5.

[0028] The two ends of the mounting shaft 44 respectively pass through the mounting holes and extend to the outside of the fixing block 41, and the two ends of the mounting shaft 44 are fixedly installed with torsion springs 49, and the two ends of the torsion spring 49 are decomposed and fixedly connected to the end of the mounting shaft 44 and the outer wall of the mounting block; when working, the torsion spring 49 is provided to make the limit block 43 flip inward, thereby facilitating the clamping of the rubber head 5.

[0029] The rubber head 5 is formed integrally by a clamping end 51 , a connecting section 52 and an abutting end 53 . The clamping end 51 is arranged between the limiting block 43 and the bottom end of the suction tube 3 .

[0030] One end of the limit block 43 extends toward the center of the suction tube 3 to the outside of the groove 42, and the end of the limit block 43 located outside the groove 42 is set to be inclined; during operation, it is convenient for the rubber head 5 to be inserted into the inside of the limit block 43 from the outside.

[0031] The inner side of the bottom end of the suction pipe 3 is provided with a tightening assembly 6, and the tightening assembly 6 includes a tube body 61, and the tube body 61 is slidably arranged inside the bottom end of the suction pipe 3, and the side wall of the tube body 61 is in contact with the inner wall of the suction pipe 3. The bottom end of the tube body 61 is fixedly connected with an abutment plate 62, and the abutment plate 62 is arranged on the outer side of the bottom end of the suction pipe 3. A sink groove 63 is opened in the inner wall of the bottom end of the suction pipe 3, and a spring 2 64 is fixedly installed inside the sink groove 63. The bottom end of the second spring 64 is fixedly connected to the inner wall of the abutment plate 62; during operation, when the clamping end 51 passes through the limit block 43, the end face of the clamping end 51 contacts the abutment plate 62, and the second spring 64 is compressed. When the clamping end 51 completely passes through the limit block 43, the second spring 64 and the abutment plate 62 cooperate to push the clamping end 51 tightly against the limit block 43, so as to stably clamp the rubber head 5 on the inner side of the limit block 43 and increase the airtightness between the rubber head 5 and the suction tube 3.

[0032] Example 2

[0033] See also Figure 5 As shown, compared with Example 1, as another embodiment of the present invention, a pad 7 is fixedly connected to the inside of the groove 42 near the middle side of the suction tube 3; when working, it is used to prevent the limit block 43 from flipping inward, so that the limit block 43 remains in a position perpendicular to the fixed block 41.

[0034] Working principle: When working, the lifting device 1 is moved to the top of the integrated circuit chip through the mobile module on the frame, and the suction head 2, the suction tube 3 and the rubber head 5 are controlled to descend through the lifting device 1, so that the rubber head 5 is in contact with the top of the integrated circuit chip. The suction head 2 is connected to the external vacuum equipment, and the suction force generated by the vacuum equipment is used to adsorb the integrated circuit chip to the bottom of the rubber head 5, so that the integrated circuit chip is sucked and processed, which is convenient for selecting the required integrated circuit chip.

[0035] When the rubber head 5 at the bottom of the suction tube 3 is worn out, the rubber head 5 is directly pulled outward, and the clamping end 51 of the rubber head 5 drives the limit block 43 to flip outward with the installation shaft 44 as the center, so that the rubber head 5 can be removed. At the same time, the limit block 43 can drive the installation shaft 44 to rotate at the same time through the internal sliding rod 47, at this time, the torsion spring 49 starts to accumulate force, and when the rubber head 5 is removed, the limit block 43 is driven to return to its original position through the torsion spring 49, and then the clamping end 51 on the new rubber head 5 is inserted from the middle position of the installation assembly 4, and the edge of the clamping end 51 first contacts the inclined surface of the end of the limit block 43, thereby forcing the limit block 43 to move outward, and the spring 1 48 is compressed. When the clamping end 51 completely passes the end of the limit block 43, the spring 1 48 pushes the limit block 43 to return to its original position, thereby making the end of the limit block 43 abut against the side wall of the connecting section 52 on the rubber head 5, thereby preventing the rubber head 5 from falling off, and thus realizing the rapid installation of the rubber head 5. In addition, when the clamping end 51 passes through the limit block 43, the end face of the clamping end 51 contacts the abutment plate 62, and the spring 2 64 is compressed. When the clamping end 51 completely passes through the limit block 43, the spring 2 64 and the abutment plate 62 cooperate to push the clamping end 51 tightly against the limit block 43, making it easier to stably clamp the rubber head 5 on the inner side of the limit block 43 and increase the air tightness between the rubber head 5 and the suction tube 3.
