Description

Technical Field

[0001] This invention relates to the field of memory module chip mounting technology, and in particular to a quick-change clamping seat for a memory module chip mounting machine nozzle. Background Technology

[0002] Memory chip mounting machines are high-precision, multi-functional pick-and-place machines in surface mount technology (SMT). They are designed to precisely mount miniaturized, high-density memory chips (DRAM, often in FBGA packages) onto PCB substrate pads. Combined with solder paste printing, reflow soldering, and AOI inspection, they form a complete memory module production line. They have extremely high requirements for mounting accuracy, vacuum stability, anti-static properties, and changeover efficiency.

[0003] The nozzles of the placement machine use vacuum negative pressure to pick up memory chips and then precisely move them to the target pads for subsequent placement processing. In memory chip placement machines, the nozzles are indeed consumables and must be maintained or even replaced frequently. The core reasons are to ensure placement accuracy, vacuum stability, yield, and equipment safety, especially since memory chips are extremely small and precise, and even a slight abnormality can lead to the scrapping of a batch of components.

[0004] To ensure work efficiency, the clamping seat needs to enable quick nozzle replacement and locking, adapting to high-speed, high-precision, and frequently changing memory chip mounting scenarios. The most common clamping seat structure currently uses a steel ball and a groove on the nozzle for elastic clamping. However, when replacing the nozzle, this method requires the nozzle sidewall to be forcibly rubbed and squeezed against the steel ball until the groove and steel ball are aligned. This installation method can easily cause minor wear on the nozzle sidewall, affecting the accuracy of the nozzle after installation. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a quick-change clamping seat for the nozzle of a memory module chip mounting machine, which enables the quick installation or removal of the nozzle body, avoids unnecessary wear on the nozzle body, and improves the accuracy after installation.

[0006] The technical solution adopted in this invention is: to provide a quick-change clamping seat for the nozzle of a memory module chip mounting machine, including a nozzle body and a nozzle chuck, wherein the upper part of the nozzle body is inserted into the nozzle chuck, and the nozzle chuck is provided with a clamping component. The clamping assembly includes multiple support rods evenly distributed circumferentially around the outside of the nozzle chuck; the length direction of the support rods is parallel to the axial direction of the nozzle chuck; the support rods are connected to the nozzle chuck via tension springs; a locking pin is fixed on the support rod; the locking pin slides radially through one side of the outer wall of the nozzle chuck; a positioning ring groove is correspondingly formed circumferentially on the outer wall of the nozzle body; the locking pin corresponds to the positioning ring groove; the tension spring is configured with a preload force to cause the locking pin to slide into the positioning ring groove and abut against the bottom of the positioning ring groove; The suction nozzle clamp is externally rotatably sleeved with a release push ring; the outer wall of the release push ring is provided with multiple arc-shaped function recesses along the circumference; the support rod corresponds one-to-one with the function recesses; when the locking pin abuts against the bottom of the positioning ring groove, the support rod is in the function recess; when the support rod is misaligned with the function recess, the locking pin separates from the positioning ring groove.

[0007] To further optimize this technical solution, a rubber sleeve is fitted and fixed to the bottom of the positioning ring groove of the quick-change clamping seat of the memory module chip mounting machine nozzle.

[0008] To further optimize this technical solution, an auxiliary pin is fixed on the support rod of the quick-change clamping seat of the nozzle of a memory module chip mounting machine; the auxiliary pin slides radially through one side of the outer wall of the nozzle chuck; a reference ring groove is correspondingly opened on the outer wall of the nozzle body in the circumferential direction; the auxiliary pin corresponds to the reference ring groove; when the locking pin abuts against the positioning ring groove, the auxiliary pin slides into the reference ring groove; when the locking pin separates from the positioning ring groove, the auxiliary pin separates from the reference ring groove.

[0009] To further optimize this technical solution, a positioning ring groove and a reference ring groove are respectively located on the upper and lower sides of the nozzle body of a memory module chip mounting machine nozzle quick-change clamping seat.

[0010] To further optimize this technical solution, a rotating cylinder is rotatably connected to the support rod of the quick-change clamping seat of the nozzle of a memory module chip mounting machine; the rotating cylinder corresponds to the release push ring.

[0011] To further optimize this technical solution, the outer wall of the release push ring of the quick-change clamping seat of the nozzle of a memory module chip mounting machine is provided with multiple arc-shaped mounting slots along the circumference; the mounting slots correspond one-to-one with the rotating drum; when the rotating drum is in the corresponding mounting slot, the locking pin separates from the positioning ring groove.

[0012] The beneficial effects of this invention are as follows: The locking pin slides radially through one side of the outer wall of the nozzle chuck. The tension spring is configured with a preload force that causes the locking pin to slide into the positioning ring groove and abut against the bottom of the positioning ring groove. Through the elastic force of the tension spring, the locking pin abuts against the positioning ring groove, thereby locking the nozzle body and the nozzle chuck together and ensuring that the nozzle body is securely installed.

[0013] The nozzle chuck is externally rotatably fitted with a release push ring. When the locking pin abuts against the bottom of the positioning ring groove, the support rod is in the action recess. Through the action recess of the release push ring, the positioning effect of the locking pin on the nozzle body is not affected. When the support rod is misaligned from the action recess, the locking pin separates from the positioning ring groove. The rotation of the release push ring can cause the action recess to be misaligned from the support rod. The outer wall of the release push ring can stretch the tension spring, moving the locking pin out of the positioning ring groove and locking the nozzle body. This facilitates the installation or removal of the nozzle body. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1-3 As shown, a quick-change clamping seat for a memory module chip mounting machine includes a nozzle body 1 and a nozzle chuck 2. The upper part of the nozzle body 1 is inserted into the nozzle chuck 2, and the nozzle chuck 2 is provided with a clamping component. The clamping assembly includes multiple support rods 3 evenly distributed circumferentially on the outside of the suction cup 2; the length direction of the support rods 3 is parallel to the axial direction of the suction cup 2; the support rods 3 are connected to the suction cup 2 by a tension spring 4; a locking pin 5 is fixed on the support rod 3; the locking pin 5 slides radially through one side of the outer wall of the suction cup 2; a positioning ring groove 6 is correspondingly opened circumferentially on the outer wall of the suction cup body 1; the locking pin 5 corresponds to the positioning ring groove 6; the tension spring 4 is configured with a preload force to cause the locking pin 5 to slide into the positioning ring groove 6 and abut against the bottom of the positioning ring groove 6; The suction nozzle clamp 2 is externally rotatably sleeved with a release push ring 7; the outer wall of the release push ring 7 is provided with multiple arc-shaped function recesses 8 along the circumference; the support rod 3 corresponds one-to-one with the function recesses 8; when the locking pin 5 abuts against the bottom of the positioning ring groove 6, the support rod 3 is in the function recess 8; when the support rod 3 is misaligned with the function recess 8, the locking pin 5 separates from the positioning ring groove 6.

[0018] In this solution, when fixing the nozzle body 1 to the nozzle clamp 2, the elastic force of the tension spring 4 is used to slide the locking pin 5 into the positioning ring groove 6 and abut against the positioning ring groove 6. This fixing method can not only position the nozzle body 1 in the axial direction, but also position the nozzle body 1 in the circumferential direction by the abutment of the locking pin 5, so that the nozzle body 1 is not easy to rotate in the nozzle clamp 2, ensuring that it still has good positional accuracy when used for a long time.

[0019] To achieve rapid replacement of the nozzle body 1, this technical solution simply involves rotating the release push ring 7 to displace the actuating recess 8 from the support rod 3. The outer wall of the release push ring 7 pushes the support rod 3, stretching the tension spring 4 and moving the locking pin 5 out of the positioning ring groove 6. This removes the obstruction to the internal space of the nozzle chuck 2, allowing the nozzle body 1 to be quickly inserted or removed. Once the nozzle body 1 is inserted to the correct depth into the nozzle chuck 2, the release push ring 7 is rotated back to the position of the support rod 3 in the actuating recess 8. The tension spring 4 is released, allowing the locking pin 5 to re-insert into the positioning ring groove 6 and engage with it, thus locking the nozzle body 1.

[0020] The above process shows that this solution will not be blocked or rubbed by the locking pins 5 when installing or removing the nozzle body 1, ensuring that no wear is caused to the outer wall of the nozzle body 1 during installation and removal, thus improving the installation accuracy.

[0021] like Figure 3 As shown, a rubber sleeve 9 is fitted and fixed to the bottom of the positioning ring groove 6. When locking the nozzle body 1, the locking pin 5 can abut against the rubber sleeve 9. The flexible buffer of the rubber sleeve 9 replaces the rigid abutment between the locking pin 5 and the bottom of the positioning ring groove 6, avoiding the nozzle body 1 from being squeezed and deformed slightly, thus improving its durability.

[0022] like Figure 1 As shown, an auxiliary insert 10 is fixed on the support rod 3; the auxiliary insert 10 slides radially through one side of the outer wall of the suction nozzle chuck 2; a reference annular groove 11 is correspondingly opened on the outer wall of the suction nozzle body 1 in the circumferential direction; the auxiliary insert 10 corresponds to the reference annular groove 11; when the locking pin 5 abuts against the positioning annular groove 6, the auxiliary insert 10 slides into the reference annular groove 11; when the locking pin 5 separates from the positioning annular groove 6, the auxiliary insert 10 separates from the reference annular groove 11.

[0023] The auxiliary insert 10, positioned within the reference annular groove 11, provides an additional layer of "safety" for the positioning of the nozzle body 1, further improving the installation accuracy. It should be noted that the auxiliary insert 10 does not need to abut against the reference annular groove 11. Additionally, it allows for verification that the replaced nozzle body 1 meets the accuracy requirements. If the auxiliary insert 10 and locking pin 5 cannot be installed correctly, it indicates deformation and the nozzle cannot be used.

[0024] like Figure 1 As shown, the positioning annular groove 6 and the reference annular groove 11 are located on the upper and lower sides of the nozzle body 1, respectively. This vertical distribution avoids the problem of local stress concentration causing the nozzle body 1 to be less durable.

[0025] like Figure 1-2 As shown, a rotating cylinder 12 is rotatably sleeved on the support rod 3; the rotating cylinder 12 corresponds to the release push ring 7. When the release push ring 7 rotates to push the support rod 3, the rotation of the rotating cylinder 12 can reduce friction, making the operation more effortless.

[0026] like Figure 2 As shown, the outer wall of the release push ring 7 has multiple arc-shaped mounting slots 13 along its circumference; each mounting slot 13 corresponds to a rotating cylinder 12; when the rotating cylinder 12 is positioned in the mounting slot 13, the locking pin 5 separates from the positioning ring groove 6. By supporting the rotating cylinder 12 through the mounting slots 13, the locking pin 5 can be temporarily positioned in a state where it is separated from the positioning ring groove 6 without using both hands, thus facilitating the installation or removal of the nozzle body 1.

Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention.
