Description

Technical Field

[0001] This application belongs to the field of material transfer technology, and more specifically, relates to an adsorption mechanism and a material transfer device. Background Technology

[0002] In the field of printed circuit board (PCB) manufacturing, especially before the PCB drilling process, there is often a transfer device used to transfer thin sheet materials such as aluminum sheets, PCB substrates, pads, and stacks formed by stacking them.

[0003] Currently, when transferring sheet materials, suction cups are typically used to pick up the sheet materials. However, in actual operation, when multiple sheet materials are stacked, electrostatic adsorption between the sheet materials or the permeability of the sheet materials themselves often causes the suction cup to pick up one or more layers of sheet materials below it when it picks up the top layer of sheet materials. This results in the abnormal situation of picking up multiple sheet materials at once, which seriously affects the accuracy and reliability of sheet material transfer. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, the main objective of this application is to provide an adsorption mechanism and a transfer device.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution: According to a first aspect of the embodiments of this application, an adsorption mechanism is provided, comprising: The fixing assembly includes a fixing sleeve and a first magnetic element, the first magnetic element being disposed on the fixing sleeve; and A sliding assembly includes a slide rod, a suction cup, a second magnetic component, and an elastic component. The slide rod is movably inserted through the fixed sleeve. The suction cup is connected to one end of the slide rod. The second magnetic component is disposed on the slide rod and is disposed opposite to the first magnetic component along the axial direction of the slide rod. One of the first magnetic component and the second magnetic component is an electromagnet. The elastic component is sleeved on the slide rod and is used to drive the slide rod to reset.

[0006] Optionally, the first magnetic component is an electromagnet, and the second magnetic component is a permanent magnet.

[0007] Optionally, the slide bar is provided with a locking part, the elastic element is located on the side of the first magnetic element facing the suction cup, and acts along the axial direction of the slide bar between the locking part and the fixing sleeve, and the second magnetic element is located on the side of the first magnetic element away from the suction cup.

[0008] Optionally, the locking part is located at one end of the slide rod near the suction cup, the elastic element is a spring, and its two ends respectively abut against the locking part and the fixing sleeve, and the second magnetic element is located at one end of the slide rod away from the suction cup.

[0009] Optionally, both the first magnetic element and the second magnetic element are block structures.

[0010] Optionally, the first magnetic component is provided with a first through hole, and the first magnetic component is sleeved and fixed on the fixing sleeve through the first through hole.

[0011] Optionally, the second magnetic component is provided with a second through hole, and the second magnetic component is sleeved and fixed on the slide rod through the second through hole.

[0012] Optionally, the slide bar is provided with an air passage, the suction cup is provided with an air hole, the air hole communicates with the air passage, and the sliding assembly further includes an air pipe connector, which is connected to the end of the slide bar away from the suction cup and communicates with the air passage.

[0013] Optionally, the fixing component further includes a fixing base, and the fixing sleeve is disposed on the fixing base.

[0014] According to a second aspect of the embodiments of this application, a transfer device is provided, including a moving mechanism and the above-mentioned adsorption mechanism, wherein the moving mechanism is used to drive the adsorption mechanism to move.

[0015] The beneficial effects of the adsorption mechanism and material transfer device provided in this application are as follows: Compared with the prior art, the adsorption mechanism of this application arranges the second magnetic component and the first magnetic component opposite to each other along the axial direction of the slide rod, with one of them being an electromagnet. After the suction cup picks up the uppermost material, the electromagnet is energized, and a magnetic attraction or repulsion force is generated between the first and second magnetic components, pushing the slide rod to slide relative to the fixed sleeve along its own axial direction. This causes the suction cup to move the material and the elastic component to store energy. After the electromagnet is de-energized, the elastic component releases energy and drives the slide rod to reset, causing the suction cup to move the material in the opposite direction. In this way, by controlling the electromagnet to be energized rapidly and repeatedly, the slide rod drives the suction cup to vibrate continuously at high frequency along the axial direction of the slide rod, shaking off the excess material adsorbed by the suction cup. This effectively ensures that the suction cup picks up only one piece of material at a time, thereby improving the accuracy and reliability of material transfer. Attached Figure Description

[0023] Technical solution: Please refer to the following: Figures 1 to 5 The adsorption mechanism provided in the embodiments of this application will now be described. The adsorption mechanism is used to adsorb sheet-like materials, which can be, but are not limited to, aluminum sheets, PCB substrates, pads, or stacks formed by stacking aluminum sheets, PCB substrates, and pads.

[0024] Please refer to the following: Figures 1 to 3 The adsorption mechanism includes a fixing component 10 and a sliding component 20. The fixing component 10 includes a fixing sleeve 11 and a first magnetic element 12. The fixing sleeve 11 is used to connect with the moving mechanism of the material transfer device, and the first magnetic element 12 is disposed on the fixing sleeve 11. The sliding component 20 includes a slide rod 21, a suction cup 22, a second magnetic element 23, and an elastic element 24. The slide rod 21 is movably inserted through the fixing sleeve 11 and is coaxially arranged with the fixing sleeve 11. The suction cup 22 is connected to one end of the slide rod 21 and is used to pick up materials. The second magnetic element 23 is disposed on the slide rod 21 and is arranged opposite to the first magnetic element 12 along the axial direction of the slide rod 21. One of the first magnetic element 12 and the second magnetic element 23 is an electromagnet. The elastic element 24 is sleeved on the slide rod 21 and is used to drive the slide rod 21 to reset when the electromagnet is de-energized.

[0025] Compared with the prior art, the adsorption mechanism provided in this application arranges the second magnetic element 23 and the first magnetic element 12 opposite to each other along the axial direction of the slide rod 21, with one of them being an electromagnet. After the suction cup 22 picks up the uppermost material, the electromagnet is energized, and a magnetic attraction or repulsion force is generated between the first magnetic element 12 and the second magnetic element 23, pushing the slide rod 21 to slide relative to the fixed sleeve 11 along its own axial direction. This causes the suction cup 22 to move the material and the elastic element 24 to store energy. After the electromagnet is de-energized, the elastic element 24 releases energy and drives the slide rod 21 to reset, causing the suction cup 22 to move the material in the opposite direction. By controlling the electromagnet to be energized rapidly and repeatedly, the slide rod 21 drives the suction cup 22 to vibrate continuously at high frequency along the axial direction of the slide rod 21, shaking off excess material adsorbed by the suction cup 22. This effectively ensures that the suction cup 22 picks up only one piece of material at a time, thereby improving the accuracy and reliability of material transfer.

[0026] Combined with appendix Figure 2 and Figure 3It is understood that the first magnetic component 12 is an electromagnet, and the second magnetic component 23 is a permanent magnet. By setting the first magnetic component 12 as an electromagnet and fixing it to the fixing sleeve 11, the electromagnet does not need to be moved, simplifying the wiring operation of the electromagnet, which helps to reduce wiring difficulty and assembly cost, and also effectively ensures the stability and reliability of the circuit connection. The second magnetic component 23 is a permanent magnet. When the electromagnet is energized, the magnetic attraction or repulsion between the first magnetic component 12 and the second magnetic component 23 can be flexibly controlled by changing the polarity of the electromagnet according to the relative position relationship between the first magnetic component 12 and the second magnetic component 23. This precisely drives the slide rod 21 to drive the suction cup 22 to vibrate at high frequency, effectively shaking off the excess material adsorbed by the suction cup 22, ensuring that only one material is picked up at a time.

[0027] Alternatively, the first magnetic component 12 can be a permanent magnet, and the second magnetic component 23 can be an electromagnet. Or, the first magnetic component 12 can be an electromagnet, and the second magnetic component 23 can be a magnetizable material. Alternatively, the first magnetic component 12 can be a magnetizable material, and the second magnetic component 23 can be an electromagnet.

[0028] Combined with appendix Figure 1 , Figure 4 and Figure 5 It is understandable that both the first magnetic component 12 and the second magnetic component 23 are block structures.

[0029] The first magnetic element 12 can be, but is not limited to, a rectangular block or a circular block. The second magnetic element 23 can be, but is not limited to, a rectangular block or a circular block. For example, the first magnetic element 12 is a rectangular block, and the second magnetic element 23 is a circular block.

[0030] By adopting a block structure for the first magnetic component 12 and the second magnetic component 23, the magnetic field area between the first magnetic component 12 and the second magnetic component 23 is larger and more evenly distributed. Thus, when the first magnetic component 12 or the second magnetic component 23, which acts as an electromagnet, is energized or de-energized, the magnetic attraction or repulsion force generated between the first magnetic component 12 and the second magnetic component 23 is larger and more stable. This allows the slide bar 21 to slide relative to the fixed sleeve 11 along its own axis in a stable and effective manner, ensuring that the high-frequency shaking action of the suction cup 22 on the material is stable and reliable, which is beneficial to improving the effect of shaking off excess material adsorbed by the suction cup 22.

[0031] Combined with appendix Figure 2 and Figure 3 It is understood that the first magnetic component 12 is provided with a first through hole 121. The first magnetic component 12 is sleeved and fixed on the fixed sleeve 11 through the first through hole 121, and the first magnetic component 12 is coaxially arranged with the slide rod 21.

[0032] The first magnetic component 12 is sleeved and fixed on the fixed sleeve 11 through the first through hole 121, which ensures the positioning accuracy and connection strength of the first magnetic component 12 on the fixed sleeve 11, and effectively guarantees the accuracy and stability of the magnetic force between the first magnetic component 12 and the second magnetic component 23.

[0033] Optionally, based on the first magnetic component 12 being sleeved on the fixed sleeve 11, the stability of the fit between the first magnetic component 12 and the fixed sleeve 11 can be enhanced by means of adhesive bonding, snap-fitting, bolt connection or threaded connection.

[0034] Optionally, the outer peripheral wall of the fixing sleeve 11 is provided with a first annular groove. When the first magnetic element 12 is sleeved on the fixing sleeve 11 through the first through hole 121, the first magnetic element 12 is locked in the first annular groove, which helps to enhance the stability of the fit between the first magnetic element 12 and the fixing sleeve 11.

[0035] Combined with appendix Figure 1 , Figure 3 and Figure 4 It is understood that the fixing component 10 also includes a fixing seat 13, which is used to connect with the moving mechanism of the material transfer device. The fixing sleeve 11 is disposed on the fixing seat 13, that is, the fixing sleeve 11 is connected to the moving mechanism of the material transfer device through the fixing seat 13.

[0036] The fixing component 10 is provided with a fixing seat 13 and the fixing sleeve 11 is set on the fixing seat 13, so that the adsorption mechanism can be easily and stably connected with the moving mechanism of the transfer device by means of the fixing seat 13. This greatly facilitates the assembly of the entire adsorption mechanism onto the moving mechanism, reduces the assembly difficulty, improves the assembly efficiency, and also enhances the stability and reliability of the connection between the adsorption mechanism and the moving mechanism, which helps to ensure the smooth operation of the adsorption mechanism during the transfer process.

[0037] Combined with appendix Figure 3 and Figure 4 It is understood that the fixed base 13 has a rectangular structure. One end of the fixed base 13 is provided with a mounting hole 131, which is used to connect with the material transfer mechanism. The other end of the fixed base 13 is provided with a fixing hole 132. The fixing sleeve 11 passes through the fixing hole 132 and is tightly fitted with the fixed base 13.

[0038] By adopting a rectangular structure for the fixed base 13, with one end of the fixed base 13 reliably connected to the material transfer mechanism through the mounting hole 131 and the other end tightly fitted to the fixed sleeve 11 through the fixing hole 132, a stable mounting base is provided for the adsorption mechanism, and the positioning of the fixed sleeve 11 is made more secure, effectively preventing loosening or displacement during high-frequency vibration, thereby improving the stability and reliability of the adsorption mechanism.

[0039] Combined with appendix Figure 3It is understood that the slide rod 21 is provided with an air passage 211, the suction cup 22 is provided with an air hole 221, the air hole 221 is connected to the air passage 211, the sliding assembly 20 also includes an air pipe connector 25, the air pipe connector 25 is connected to the end of the slide rod 21 away from the suction cup 22 and is connected to the air passage 211, and the air pipe connector 25 is used to connect an external vacuum pump.

[0040] For example, the suction cup 22 is connected to the lower end of the slide bar 21, and the air pipe connector 25 is connected to the upper end of the slide bar 21.

[0041] When suctioning materials, an external vacuum pump is connected to the air passage 211 inside the slide rod 21 through the air pipe connector 25. Since the suction cup 22 is provided with an air hole 221 that communicates with the air passage 211, the external vacuum pump provides negative pressure to the air passage 211 inside the slide rod 21 through the air pipe connector 25. This negative pressure is transmitted to the air hole 221 on the suction cup 22 through the air passage 211, forming a negative pressure at the air hole 221, thereby generating an adsorption force, enabling the suction cup 22 to suction materials.

[0042] By opening an air passage 211 inside the slide rod 21 and connecting the air hole 221 of the suction cup 22 to the air passage 211, and connecting the air pipe connector 25 for connecting an external vacuum pump to the end of the slide rod 21 away from the suction cup 22, the air circuit system is integrated inside the slide rod 21. This makes the negative pressure transmission path more direct and compact, which not only significantly reduces the risk of entanglement and interference of external pipes and ensures the air circuit sealing and stability of the sliding assembly 20 during high-frequency vibration, but also enables the suction cup 22 to quickly form a stable and uniform negative pressure adsorption force when sucking up materials, effectively improving adsorption efficiency and reliability. At the same time, by placing the air pipe connector 25 at the end of the slide rod 21 away from the suction cup 22, it is convenient to connect the air pipe connector 25 to an external vacuum source, simplifying the overall structural layout and improving the integration and maintenance convenience of the sliding assembly 20.

[0043] Combined with appendix Figure 2 and Figure 3 It is understood that the second magnetic component 23 is provided with a second through hole 231. The second magnetic component 23 is sleeved and fixed on the slide rod 21 through the second through hole 231, and the second magnetic component 23 and the slide rod 21 are coaxially arranged.

[0044] The second magnetic component 23 is sleeved and fixed on the slide rod 21 through the second through hole 231, which ensures the positioning accuracy and connection strength of the second magnetic component 23 on the slide rod 21, effectively preventing loosening or displacement during high-frequency vibration, thereby ensuring the accuracy and stability of the magnetic force between the first magnetic component 12 and the second magnetic component 23.

[0045] Combined with appendix Figures 1 to 3It is understood that the second magnetic element 23 is located at the end of the slide rod 21 away from the suction cup 22, and the second magnetic element 23 is located on the side of the first magnetic element 12 opposite to the suction cup 22. The sliding assembly 20 also includes a retaining ring 26, which is fixedly sleeved on the slide rod 21, and the retaining ring 26 abuts against the side of the second magnetic element 23 opposite to the suction cup 22. The retaining ring 26 can be, but is not limited to, a nut. By restricting the second magnetic element 23 with the retaining ring 26, the stability of the second magnetic element 23 sleeved on the slide rod 21 is enhanced.

[0046] Optionally, in addition to the second magnetic component 23 being sleeved on the slide rod 21, the stability of the fit between the second magnetic component 23 and the slide rod 21 can be enhanced by means of adhesive bonding, snap-fitting, bolt connection or threaded connection.

[0047] Optionally, a second annular groove is provided on the outer peripheral wall of the slide rod 21. When the second magnetic element 23 is sleeved on the slide rod 21 through the second through hole 231, the second magnetic element 23 is locked in the second annular groove, which helps to enhance the stability of the fit between the second magnetic element 23 and the slide rod 21.

[0048] A guide structure is provided between the slide rod 21 and the fixed sleeve 11. The guide structure is used to guide the slide rod 21 to slide linearly along the axial direction of the fixed sleeve 11, which effectively prevents the slide rod 21 from deviating or getting stuck during the sliding process relative to the fixed sleeve 11. This not only improves the reliability and consistency of the shaking action of the slide rod 21, thereby ensuring the effect of shaking off excess material, but also reduces abnormal wear between the sliding component 20 and the fixed sleeve 11, and extends the service life of the adsorption mechanism.

[0049] Optionally, the guide structure is a guide protrusion provided on the inner surface of the fixed sleeve 11, and the outer peripheral wall of the slide rod 21 is provided with a guide groove, with the guide protrusion cooperating with the guide groove.

[0050] Optionally, the outer surface of the slide bar 21 is provided with a wear-resistant coating, which includes one of the following: titanium carbide layer, titanium nitride layer, aluminum carbonitride layer, chromium nitride layer, or tungsten carbide layer. By providing a wear-resistant coating on the outer surface of the slide bar 21, the wear caused by friction during frequent sliding of the slide bar 21 relative to the fixed sleeve 11 can be effectively reduced.

[0051] Combined with appendix Figure 3 and Figure 5 It is understandable that the slide bar 21 is provided with a locking part 212, the elastic element 24 is located on the side of the first magnetic element 12 facing the suction cup 22, and the elastic element 24 acts on the locking part 212 and the fixing sleeve 11 along the axial direction of the slide bar 21, and the second magnetic element is located on the side of the first magnetic element 12 away from the suction cup 22.

[0052] For example, the axis of the slide rod 21 is parallel to the vertical direction. The suction cup 22 is connected to the lower end of the slide rod 21. The second magnetic element 23 is located above the first magnetic element 12. The first magnetic element 12 is an electromagnet, and the second magnetic element 23 is a permanent magnet. After the suction cup 22 picks up the top layer of material, the electromagnet is energized. A magnetic repulsive force is generated between the first magnetic element 12 and the second magnetic element 23. The magnetic repulsive force pushes the slide rod 21 to slide upward relative to the fixed sleeve 11. The slide rod 21 drives the suction cup 22 to rise, and the elastic element 24 is compressed and stores energy. Subsequently, the electromagnet is de-energized, the elastic element 24 extends and releases energy, pushing the slide rod 21 to slide downward relative to the fixed sleeve 11. The slide rod 21 drives the suction cup 22 to descend. In this way, by frequently switching the electromagnet on and off, the slide rod 21 drives the suction cup 22 to shake up and down rapidly, so as to shake off the excess material picked up by the suction cup 22, effectively preventing the suction cup 22 from picking up multiple layers of material at a time.

[0053] By setting a locking part 212 on the slide rod 21, and placing the elastic element 24 on the side of the first magnetic element 12 facing the suction cup 22, with the elastic element 24 abutting against the locking part 212 and the fixing sleeve 11 along the axial direction of the slide rod 21, and the second magnetic element 23 on the side of the first magnetic element 12 away from the suction cup 22, the magnetic force between the first magnetic element 12 and the second magnetic element 23 disappears rapidly when the electromagnet is de-energized. At this time, the compressed elastic element 24 immediately releases its elastic potential energy, pushing the slide rod 21 to move the suction cup 22 and the material being sucked down quickly. At the same time, combined with the gravity of the slide rod 21 assembly and the material being sucked up by the suction cup 22, the downward movement speed of the slide rod 21 is further enhanced. In this way, through the dual action of the energy release of the elastic element 24 and the gravity of the material, the action response speed and shaking impact force of the slide rod 21 when resetting are significantly improved, thereby efficiently and reliably shaking off the excess material adsorbed on the suction cup 22, effectively avoiding the adhesion of multiple layers of material and ensuring the accuracy of single material retrieval.

[0054] Combined with appendix Figure 3 and Figure 5 It is understandable that the locking part 212 is located at the end of the slide rod 21 near the suction cup 22, the elastic element 24 is a spring, one end of the elastic element 24 abuts against the locking part 212, and the other end of the elastic element 24 abuts against the end of the fixing sleeve 11 near the suction cup 22. The second magnetic element 23 is located at the end of the slide rod 21 away from the suction cup 22. When the electromagnet is energized, a magnetic repulsive force is generated between the first magnetic element 12 and the second magnetic element 23. Of course, the elastic element 24 can also be an elastic rubber sleeve or a corrugated metal sleeve, etc.

[0055] Alternatively, the axis of the slide rod 21 is parallel to the vertical direction, one end of the elastic element 24 is connected to the locking part 212, and the other end of the elastic element 24 is connected to the end of the fixing sleeve 11 near the suction cup 22. The second magnetic element 23 is located between the first magnetic element 12 and the elastic element 24 along the axis of the slide rod 21. When the electromagnet is energized, a magnetic attraction is generated between the first magnetic element 12 and the second magnetic element 23, driving the slide rod 21 to lift the suction cup 22, and the elastic element 24 extends and stores energy. After the electromagnet is de-energized, the elastic element 24 shortens and releases energy, driving the slide rod 21 and the suction cup 22 to descend and reset. In this way, by frequently switching the electromagnet on and off, the slide rod 21 drives the suction cup 22 to shake up and down rapidly, so as to shake off the excess material adsorbed by the suction cup 22.

[0056] Alternatively, the axis of the slide rod 21 is parallel to the vertical direction, the second magnetic element 23 is located above the first magnetic element 12, and the elastic element 24 is located between the first magnetic element 12 and the second magnetic element 23. One end of the elastic element 24 is connected to the fixed sleeve 11 or the first magnetic element 12, and the other end of the elastic element 24 is connected to the second magnetic element 23. When the electromagnet is energized, a magnetic repulsive force is generated between the first magnetic element 12 and the second magnetic element 23, pushing the slide rod 21 to slide upward relative to the fixed sleeve 11. The slide rod 21 drives the suction cup 22 to rise, and the elastic element 24 extends and stores energy. Subsequently, when the electromagnet is de-energized, the elastic element 24 shortens and releases energy, pushing the slide rod 21 to slide downward relative to the fixed sleeve 11, and the slide rod 21 drives the suction cup 22 to descend. In this way, by frequently switching the electromagnet on and off, the slide rod 21 drives the suction cup 22 to shake up and down rapidly, shaking off excess material adsorbed by the suction cup 22, effectively preventing the suction cup 22 from adsorbing multiple layers of material at a time.

[0057] Alternatively, the axis of the slide rod 21 is parallel to the vertical direction, the second magnetic element 23 is located above the first magnetic element 12, and the elastic element 24 is located between the first magnetic element 12 and the second magnetic element 23. One end of the elastic element 24 abuts against the fixed sleeve 11 or the first magnetic element 12, and the other end of the elastic element 24 abuts against the second magnetic element 23. When the electromagnet is energized, a magnetic attraction is generated between the first magnetic element 12 and the second magnetic element 23, pushing the slide rod 21 to slide downward relative to the fixed sleeve 11. The slide rod 21 drives the suction cup 22 to descend, and the elastic element 24 shortens and stores energy. Subsequently, when the electromagnet is de-energized, the elastic element 24 extends and releases energy, pushing the slide rod 21 to slide upward relative to the fixed sleeve 11, and the slide rod 21 drives the suction cup 22 to rise. In this way, by frequently switching the electromagnet on and off, the slide rod 21 drives the suction cup 22 to shake up and down rapidly, shaking off excess material adsorbed by the suction cup 22, effectively preventing the suction cup 22 from adsorbing multiple layers of material at a time.
