Abstract
Description
Technical Field
[0001] This utility model relates to the field of chip mounting head material feeding technology, specifically a novel magnetic connection protection module. Background Technology
[0002] A pick-and-place machine picks up surface mount devices (SMD) from a pick-and-place head, moves the SMD to the designated position according to computer positioning, and then releases the SMD. This process accurately places the SMD devices into preset positions on a PCB (Printed Circuit Board). It is widely used in the design and manufacturing of electronic components and integrated circuits.
[0003] In existing technologies, threaded connectors used in pick-and-place machines require high precision in the machining of related parts, especially with extremely strict dimensional and positional tolerances (coaxiality and perpendicularity must be within 0.005mm). Assembly accuracy is also difficult to guarantee, resulting in a high defect rate and high production costs. Furthermore, in the event of a collision, instantaneous separation of the Z-axis from the connector cannot be guaranteed. Failure to separate can cause the Z-axis to bend and deform under impact force, potentially damaging high-precision sliders and causing significant production losses. Two-button flexible connectors require highly skilled workers to assemble; improper assembly can easily lead to concentricity issues, and collisions can easily damage the flexible connectors, requiring replacement, resulting in slightly higher maintenance costs.
[0004] In view of this, we propose a novel magnetic connection protection module. Utility Model Content
[0005] The purpose of this invention is to provide a novel magnetic connection protection module to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel magnetic connection protection module, comprising an upper permanent magnet positioning sleeve, a lower permanent magnet positioning sleeve, and a suction nozzle. An upper permanent magnet is detachably installed inside the upper permanent magnet positioning sleeve, and a lower permanent magnet is detachably installed inside the lower permanent magnet positioning sleeve. The upper and lower permanent magnet positioning sleeves are mutually attracted by the magnetic properties of the upper and lower permanent magnet components. When a radial collision occurs between the upper and lower permanent magnet positioning sleeves, the lower permanent magnet positioning sleeve causes the suction nozzle to separate instantly, protecting the suction nozzle and connecting shaft from damage.
[0007] Optionally, the top of the upper permanent magnet positioning sleeve is detachably connected to the end of the connecting shaft.
[0008] Optionally, the bottom of the lower permanent magnet positioning sleeve is detachably connected to a suction nozzle, which is used to adsorb materials.
[0009] Optionally, the upper permanent magnet and the lower permanent magnet are matched in size.
[0010] Optionally, the lower permanent magnet positioning sleeve is coated with a magnetic shielding layer, which can effectively isolate the magnetic force of the permanent magnet from the suction nozzle and avoid the problem of easily adsorbing magnetic materials.
[0011] Compared with the prior art, this utility model provides a novel magnetic connection protection module, which has the following beneficial effects:
[0012] 1. This new type of magnetic connection protection module connects the connecting shaft and the suction nozzle through magnetic force, and repeated assembly and disassembly will not cause damage to the workpiece in terms of physical connection; at the same time, when the upper permanent magnet positioning sleeve and the lower permanent magnet positioning sleeve collide radially, the lower permanent magnet positioning sleeve drives the suction nozzle to separate instantly, protecting the suction nozzle and the connecting shaft from damage.
[0013] 2. This new type of magnetic connection protection module has a magnetic shielding layer coated on the outer part of the lower permanent magnet positioning sleeve, which can effectively isolate the magnetic force of the permanent magnet from the suction nozzle and avoid the problem of easily adsorbing magnetic materials.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] like Figure 1 As shown, this utility model provides a technical solution: a novel magnetic connection protection module, including an upper permanent magnet positioning sleeve 2, a lower permanent magnet positioning sleeve 5, and a suction nozzle 6. An upper permanent magnet 3 is detachably installed inside the upper permanent magnet positioning sleeve 2, and a lower permanent magnet 4 is detachably installed inside the lower permanent magnet positioning sleeve 5. The upper and lower permanent magnet positioning sleeves 2 and 5 are mutually attracted by the magnetic attraction of the upper permanent magnet 3 and the lower permanent magnet 4. In this embodiment, the connecting shaft 1 and the suction nozzle 6 are magnetically connected, and repeated assembly and disassembly will not cause damage to the workpiece at the physical connection. Simultaneously, when the upper and lower permanent magnet positioning sleeves 2 and 5 collide radially, the lower permanent magnet positioning sleeve 5 causes the suction nozzle 6 to separate instantly, protecting the suction nozzle 6 and the connecting shaft 1 from damage.
[0018] The top of the upper permanent magnet positioning sleeve 2 is detachably connected to the end of the connecting shaft 1. The bottom of the lower permanent magnet positioning sleeve 5 is detachably connected to a suction nozzle 6. The upper permanent magnet 3 and the lower permanent magnet 4 are sized to match.
[0019] The lower permanent magnet positioning sleeve 5 is coated with a magnetic shielding layer, which can effectively isolate the magnetic force of the permanent magnet from the suction nozzle and avoid the problem of easily adsorbing magnetic materials.
[0020] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
