Description

Technical Field

[0001] The present application relates to the technical field of product packaging, and in particular to a suction nozzle and a transfer device. Background Art

[0002] Ceramic substrate (HTCC, High-Temperature Co-fired Ceramic), also known as high-temperature co-fired multilayer ceramic, needs to be dried and hardened at 1300℃~1600℃ to form a green embryo, and then the holes are filled and the circuits are printed by screen printing technology, and finally the layers are stacked and sintered to form. Ceramic substrates have excellent electrical insulation properties, high thermal conductivity, excellent soft fiber welding performance and high adhesion strength, and are widely used in industries such as integrated circuits, chips and camera modules.

[0003] During packaging, capacitors, resistors, LDOs, Driver ICs and other components are usually mounted on the ceramic substrate first, and then reflowed and cured to form an overall structure. The surface-mounted ceramic substrate is then transferred to another tray by a robot for subsequent operations. However, since there are multiple components distributed on the ceramic substrate, there is a risk of damaging the components by directly clamping them with a robot, which seriously affects product quality. Therefore, it is urgent to find a transfer device for transferring workpieces that have completed surface assembly. Utility Model Content

[0034] See also Figure 1 and Figure 2 The embodiment of the present application provides a suction nozzle, which includes: a connecting head 100, provided with a connecting hole 101, and the connecting hole 101 is connected to the vacuum unit 10; a suction piece 200, provided with a suction hole 201 for adsorbing a workpiece 1 to be processed; and an elastic component 300, including a telescopic piece 310 and an elastic piece 320, the two ends of the telescopic piece 310 are respectively connected to the connecting head 100 and the suction piece 200, the telescopic through hole 301 is provided on the telescopic piece 310, the suction hole 201 is connected to the connecting hole 101 through the telescopic through hole 301, and the elastic piece 320 is arranged between the connecting head 100 and the suction piece 200, and is used to provide an elastic force for the telescopic piece 310 to return to its original position.

[0035] Compared with the traditional manipulator's direct clamping and fixing method of the workpiece 1 to be processed, the technical solution of the present application sets an elastic component 300 between the adsorption component 200 and the connecting head 100, and the elastic component 300 includes a retractable retractable component 310 and an elastic component 320 with a buffering force. In this way, the retractable through hole 301 on the retractable component 310 is intended to achieve a retractable connection between the connecting hole 101 on the connecting head 100 and the suction hole 201 on the adsorption component 200, so that the suction nozzle can ensure the patency of the vacuum adsorption air path while buffering and offsetting the contact stress at its adsorption end, thereby achieving adsorption and fixation of the workpiece 1 to be processed; at the same time, at least part of the elastic force of the elastic component 320 is intended to offset the contact stress generated when the adsorption component 200 is released to resist the workpiece 1 to be processed, so as to achieve flexible adsorption and fixation of the adsorption component 200 and the workpiece 1 to be processed, avoid mechanical damage, improve the quality and yield rate of the workpiece 1 to be processed, and extend the service life of the suction nozzle.

[0036] Specifically, the suction nozzle is configured as a composite component including at least a connector 100, an adsorbent 200 and an elastic component 300. The connector 100 may be a nearly rectangular metal block structure, wherein a connecting hole 101 is provided at the middle position thereof, and the connecting hole 101 is connected to the vacuum unit 10. The edges of the connector 100 are provided with smooth chamfers to prevent the edges from scratching the fingers or the outer wall of the equipment, thereby improving the safety of use or operation. The adsorbent 200 may be an anti-static structure with at least one suction claw, which can grasp and fix the suction nozzle and the workpiece 1 to be processed by adsorbing the avoidance area 12 corresponding to the workpiece 1 to be processed. The elastic component 300 is configured as a composite component including at least a telescopic member 310 and an elastic member 320. The telescopic member 310 can be a telescopic sleeve rod structure with a certain rigidity, and its two ends can be rigidly connected to the connecting head 100 and the adsorption member 200 respectively by welding or bonding, so as to improve the connection stability and reliability of the three through rigid connection, thereby improving the connection reliability between the telescopic via 301 and the connecting hole 101 and the suction hole 201, avoiding disconnection at the connection between the telescopic via 301 and the connecting hole 101 / suction hole 201, and ensuring the feasibility of vacuum adsorption; at the same time, the telescopic member 310 can also provide a certain rigidity to the elastic component 300, enhance the overall hardness of the elastic component 300, avoid the elastic component 300 being squeezed and deformed too much, and affect the alignment and fit of the adsorption member 200 and the workpiece 1 to be processed, thereby improving the adsorption reliability and adsorption firmness of the adsorption end side. The elastic member 320 can be a spring, which can be sleeved on the outside of the telescopic member 310 and spaced from the telescopic member 310 to avoid interfering with the telescopic operation of the telescopic member 310; the two ends of the elastic member 320 can be respectively abutted in the groove of the connector 100 and the groove of the adsorbent 200 to improve the connection stability of the elastic member 320 with the connector 100 and the adsorbent 200. In addition, the telescopic member 310 can also be used as an axial limiter of the elastic member 320, which can effectively prevent the elastic member 320 from deviating from its axis and deforming, so that the elastic member 320 provides a buffer elastic force in its axial direction to offset the contact stress along its axial direction generated when the adsorbent 200 abuts against the workpiece 1 to be processed, improve the offset effect of the contact stress, improve the buffering effect on the adsorption end side, reduce the mechanical damage to the workpiece 1 to be processed and the suction nozzle, extend the service life of the suction nozzle, and improve the quality and yield rate of the workpiece 1 to be processed. The suction nozzle provided in this example has a simple structure and a compact layout, which is conducive to industrial production.

[0037] Of course, in other embodiments, a first connecting plate is provided on the side of the connector 100 facing the adsorption member 200, and a second connecting plate is provided on the side of the adsorption member 200 facing the connector 100. The second connecting plate is arranged opposite to the first connecting plate, and a plurality of groups of limiting columns are correspondingly arranged on the two, and the plurality of groups of limiting columns are spaced and distributed around the periphery of the telescopic member 310. The elastic member 320 can also be arranged in plurality, one elastic member 320 corresponds to a group of limiting columns, and the two ends of the elastic member 320 are respectively sleeved on the outside of the two corresponding limiting columns to be connected to the first connecting plate and the second connecting plate respectively, thereby realizing the elastic connection between the connector 100 and the adsorption head 210. When the adsorption member 200 contacts the workpiece 1 to be processed, it can provide buffering potential energy to the telescopic member 310, thereby realizing the flexible connection between the adsorption member 200 and the workpiece 1 to be processed. The specific connection method between the elastic member 320 and the telescopic member 310 is not limited here, as long as the elastic member 320 can provide buffering potential energy for the telescopic member 310.

[0038] like Figures 1 to 4 As shown, in a possible embodiment, the telescopic member 310 includes a first movable part 311 and a second movable part 312 that are movably connected, and the end of the first movable part 311 away from the second movable part 312 is connected to the connecting head 100, and the end of the second movable part 312 away from the adsorption part 200 is connected to the adsorption part 200.

[0039] In this embodiment, the specific configuration of the telescopic member 310 is optimized. Specifically, the telescopic member 310 is configured to be a composite member including at least a first movable portion 311 and a second movable portion 312. The first movable portion 311 can be a hollow rod-shaped structure, on which a sleeve hole 3011 communicating with the connecting hole 101 is provided, and the size of the sleeve hole 3011 is slightly larger than the outer diameter of the second movable portion 312, so as to insert the second movable portion 312. The second movable portion 312 can be a hollow rod-shaped structure, on which a through hole 3012 communicating with the suction hole 201 is provided, and the size of the through hole 3012 is smaller than the size of the sleeve hole 3011. The through hole 3012 can be movably plugged into the sleeve hole 3011 through the second movable portion 312, and at least part of the sleeve hole 3011 and the sleeve hole 3011 constitute the aforementioned telescopic through hole 301. In this way, the gas flow inside the suction nozzle is as follows: the gas passes through the connection hole 101 → part of the sleeve hole 3011, the through hole 3012 (telescopic through hole 301) → the suction hole 201 in sequence and is sucked away by the vacuum unit 10, and then a negative pressure adsorption surface is formed on the side of the suction hole 201 away from the telescopic through hole 301, and the surface of the workpiece 1 to be processed located at the negative pressure adsorption surface is firmly adsorbed to achieve adsorption and fixation of the workpiece 1 to be processed. The telescopic member 310 provided in this example has a simple structure, a compact layout, and occupies a small radial space, leaving ample space for the assembly of the elastic member 320, which is conducive to realizing a miniaturized layout of the suction nozzle.

[0040] In one example, the telescopic member 310 further includes a locking limiter (not shown in the figure), which may be a combination of a protrusion and a sliding groove, and is disposed between the first movable portion 311 and the second movable portion 312. For example, the sliding groove may be disposed on the inner wall of the first movable portion 311, and the protrusion may be disposed on the outer wall of the second movable portion 312, or the sliding groove may be disposed on the outer wall of the second movable portion 312, and the protrusion may be disposed on the inner wall of the first movable portion 311. In this way, the first movable portion 311 and the second movable portion 312 are prevented from continuing to move, and the excessive contraction of the telescopic member 310 may be avoided to affect the buffering effect of the adsorbent 200, or the excessive extension of the telescopic member 310 may be avoided to cause the first movable portion 311 to fall out of the second movable portion 312 and cannot be used any more, thereby improving the reliability of the telescopic member 310; or, the misalignment of the first movable portion 311 and the second movable portion 312 in their circumferential direction may be avoided, thereby improving the adsorption accuracy of the adsorbent 200 on the workpiece 1 to be processed, and improving the adsorption effect.

[0041] like Figures 1 to 3 As shown, in a possible implementation, the elastic component 300 further includes a first limiter 330 , which is disposed on the outer side of the first movable portion 311 close to the connector 100 , and the elastic member 320 is disposed between the first limiter 330 and the adsorption member 200 .

[0042] In this embodiment, the specific configuration of the elastic component 300 is further optimized. Specifically, the elastic component 300 is configured as a composite component including at least a telescopic component 310, an elastic component 320 and a first position-limiting component 330. The first position-limiting component 330 can be a disc structure, which can be sleeved on the outside of the first movable part 311 by welding or bonding, etc., to improve the connection tightness between the first position-limiting component 330 and the first movable part 311; the first position-limiting component 330 can extend radially outward along the first movable part 311 to limit the elastic component 320 in the radial direction, so that one end of the elastic component 320 can directly abut on the first position-limiting component 330 without abutting on the connector 100, thereby reducing the material selection requirements for the elastic component 320 and improving the universality of the nozzle. The elastic component 300 provided in this example has lower requirements on the elastic threshold of the elastic member 320, which facilitates material acquisition; the elastic member 320 that meets the requirements can be adapted by setting the distance between the first limit member 330 and the adsorption member 200, which has higher flexibility and a wider range of applications.

[0043] like Figure 1 and Figure 3As shown, in a possible implementation, a weight-reducing notch 302 is provided on the outer wall of the first movable portion 311, and the weight-reducing notch 302 is located on the side of the first stopper 330 facing the adsorption member 200. In this example, the weight-reducing notch 302 is provided to reduce the overall weight of the first movable portion 311, thereby reducing the overall weight of the suction nozzle and facilitating the transfer of the suction nozzle; and the weight-reducing notch 302 can also reduce the buffering load of the elastic member 320, thereby improving the buffering effect on the workpiece 1 to be processed and improving the flexible connection effect.

[0044] like Figures 1 to 4 As shown, in a possible implementation, the elastic component 300 further includes a second limit member 340 , which is connected to a side of the second movable portion 312 close to the adsorption member 200 , and the elastic member 320 is disposed between the first limit member 330 and the second limit member 340 .

[0045] In this embodiment, the specific configuration of the elastic component 300 is further optimized. Specifically, the elastic component 300 is configured as a composite component including at least a telescopic member 310, an elastic member 320, a first limiting member 330 and a second limiting member 340. The second limiting member 340 can be a disc structure, which can be sleeved on the outer side of the second movable part 312 by welding or bonding to improve the connection tightness between the second limiting member 340 and the second movable part 312; the second limiting member 340 can extend radially outward along the second movable part 312 to limit the elastic member 320 in the radial direction, so that the other end of the elastic member 320 can directly abut on the second limiting member 340 without abutting on the adsorption member 200, thereby reducing the interference of the elastic member 320 with the position of the adsorption member 200 during compression deformation and improving the adsorption effect of the adsorption member 200. In addition, by limiting the position of the elastic member 320 by the first limiting member 330 and the second limiting member 340 , the elasticity threshold requirement for the elastic member 320 can be further reduced, thereby increasing the selectable range of the elastic member 320 .

[0046] In a possible implementation manner, the elastic component 300 further includes a sealing member (not shown in the figure), which is disposed between the first movable portion 311 and the second movable portion 312 .

[0047] In this embodiment, the specific configuration of the elastic component 300 is further optimized. Specifically, the elastic component 300 is configured as a composite component including at least a telescopic component 310, an elastic component 320 and a sealing component. The sealing component can be a soft rubber ring, which is sleeved outside the second movable part 312 and pressed against the inner wall of the first movable part 311, so as to achieve sealing of the gap between the first movable part 311 and the second movable part 312, improve the sealing connectivity between the first movable part 311 and the second movable part 312, improve the vacuum adsorption force, and improve the vacuum adsorption effect. The elastic component 300 provided in this example has a better sealing effect and a better vacuum adsorption effect.

[0048] In one example, in order to ensure smooth movement of the first movable part 311 and the second movable part 312, lubricating oil may be applied to the seal, the inner wall of the first movable part 311, and the outer wall of the second movable part 312. In this way, the first movable part 311 and the second movable part 312 may be oil-sealed by the lubricating oil, thereby further enhancing the sealing performance of the two and improving the vacuum adsorption effect.

[0049] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in a possible embodiment, the adsorption component 200 includes an adsorption head 210 and an adsorption claw 220 connected to the side of the adsorption head 210 away from the elastic component 300, and an adsorption cavity 202 is provided in the adsorption head 210, and the adsorption cavity 202 is connected to the telescopic through hole 301, and the suction hole 201 is provided in the adsorption claw 220, and the suction hole 201 is connected to the adsorption cavity 202.

[0050] In this embodiment, the specific configuration of the adsorption member 200 is optimized. Specifically, the adsorption member 200 is configured as a combined component including at least an adsorption head 210 and an adsorption claw 220. The adsorption head 210 can be a nearly rectangular box-shaped structure, which is hollow inside to form an adsorption chamber 202; the top of the adsorption chamber 202 is provided with an upper hole for communicating with the telescopic through hole 301, and the size of the upper hole is equivalent to the size of the telescopic through hole 301, so as to dock and communicate with the telescopic through hole 301; the bottom is provided with a lower hole for communicating with the suction hole 201, and the size of the lower hole is equivalent to the size of the suction hole 201, so as to dock and communicate with the suction hole 201; the size of the upper hole is greater than or equal to the size of the lower hole, so as to ensure that a negative pressure adsorption surface is formed on the free end side of the adsorption claw 220. The suction claw 220 can be a columnar structure, which is hollow inside to form a suction hole 201; the cross-sectional area of ​​the suction claw 220 is smaller than the cross-sectional area of ​​the suction head 210, so as to avoid components on the workpiece 1 to be processed, achieve precise suction and grasping of the workpiece 1 to be processed, and at the same time, enhance the suction force in this area and improve the firmness of the suction.

[0051] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in a possible implementation, a plurality of avoidance areas 12 for avoiding components are provided on the workpiece 1 to be processed, and a plurality of adsorption claws 220 are provided, and one adsorption claw 220 abuts against and adsorbs one avoidance area 12. In this example, the number and position of the adsorption claws 220 can be designed according to the position of the avoidance area 12 on the workpiece 1 to be processed, so as to increase the contact area between the adsorption claws 220 and the workpiece 1 to be processed, enhance the adsorption firmness of the workpiece 1 to be processed, and help improve the clamping stability of the workpiece 1 to be processed during the transfer process.

[0052] In one example, the cross-sectional area of ​​the suction claw 220 can be designed according to the area of ​​the avoidance zone 12 on the workpiece 1 to be processed. The cross-sectional areas of multiple suction claws 220 can be different, and the sizes of multiple suction holes 201 can also be different, so as to match the areas of multiple avoidance zones 12, thereby maximizing the contact area between the suction claw 220 and the avoidance zone 12, increasing the suction force of the suction claw 220 on the negative pressure adsorption surface side, and improving the adsorption and fixing effect.

[0053] Of course, in other embodiments, the cross-sectional areas of the plurality of suction claws 220 may also be the same to facilitate production and processing and improve production efficiency.

[0054] In a possible implementation, the adsorbent 200 is made of any one of organic glass, vinyl polymer, polycarbonate, polyoxymethylene, propargyl alcohol, polyethylene, a mixture of polyetheretherketone and carbon fiber, a mixture of carbon fiber and resin, phenolic resin, glass fiber or polyvinyl chloride.

[0055] In this embodiment, the specific material of the adsorbent 200 is optimized. Specifically, the adsorbent 200 can be made of antistatic material to reduce the interference with the electrical components on the workpiece 1 to be processed and improve the performance of the workpiece 1 to be processed. For example, the material of the adsorbent 200 can be any one of antistatic plexiglass, antistatic PVC, antistatic PC, antistatic POM, antistatic PA, antistatic PE, antistatic PEEK, antistatic bakelite, antistatic glass fiber, antistatic Ingon, antistatic synthetic stone, etc. For example, but not limited to, the material of the adsorbent 200 is POM material to improve the impact resistance and antistatic performance of the adsorbent 200. It can be understood that the antistatic value of all parts of the adsorbent 200 is the same, and the overall resistance value is approximately 10 E8 Ω~10 E11 Ω.

[0056] In addition, if Figure 7 As shown, the present application also provides a transfer device, including a vacuum unit 10 and the suction nozzle as described above, and the vacuum unit 10 is connected to a connecting hole 101 on a connecting head 100 of the suction nozzle.

[0057] In this embodiment, a transfer device capable of flexible adsorption is provided, which minimizes mechanical damage to the workpiece 1 to be processed and the suction nozzle, has a long service life of the suction nozzle, and has high quality and high yield rate of the processed product. Specifically, the transfer device is configured as a combined component including at least a vacuum unit 10 and a suction nozzle. The vacuum unit 10 can be a vacuum device with a vacuum pump, which is connected to the suction nozzle to form a negative pressure adsorption surface on the adsorption end side of the suction part 200 of the suction nozzle to achieve adsorption and fixation of a specified area of ​​the workpiece 1 to be processed. The transfer device provided in this example can manually move the position of the suction nozzle, which is suitable for transferring a small number of workpieces 1 to be processed, thereby reducing processing costs.

[0058] In addition, the specific structure of the suction nozzle refers to the above-mentioned embodiments. Since the transfer device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0059] like Figure 7 As shown, in a possible implementation, it also includes a moving unit 20, a detection unit 30 and a control unit 40. The working end of the moving unit 20 is connected to the suction nozzle. The detection unit 30 is used to detect the position of the workpiece 1 to be processed. The control unit 40 is electrically connected to the detection unit 30, the moving unit 20 and the vacuum unit 10 respectively. The control unit 40 is configured to receive and process the position information detected by the detection unit 30, and control the moving unit 20 to drive the suction nozzle to move according to the position information; and the control unit 40 is configured to control the operation of the vacuum unit 10.

[0060] In this embodiment, the specific configuration of the transfer device is further optimized. Specifically, the transfer device is configured as a combination of at least a vacuum unit 10, a suction nozzle, a moving unit 20, a detection unit 30 and a control unit 40. The moving unit 20 can be a manipulator or a six-axis robot, which can clamp the suction nozzle or be connected to the suction nozzle to achieve the position movement of the suction nozzle. The detection unit 30 can be a miniature industrial camera or a position sensor, and the control unit 40 can be a main control circuit board or chip, etc. The control unit 40 can receive and process the position information transmitted by the detection unit 30, and control the moving unit 20 to move the suction nozzle to the position of the original carrier where the workpiece 1 to be processed is placed according to the position information; then, control the vacuum unit 10 to perform evacuation operation to form negative pressure adsorption between the suction nozzle and the workpiece 1 to be processed, and fix the workpiece 1 to be processed on the suction nozzle; then, drive the moving unit 20 to transfer the suction nozzle with the workpiece 1 to be processed adsorbed and fixed to the specified position of another carrier; finally, control the vacuum unit 10 to stop the operation, and control the moving unit 20 to move the suction nozzle to the position of the original carrier where another workpiece 1 to be processed is placed, and transfer another workpiece 1 to be processed, and repeat this process until all the workpieces 1 to be processed on the original carrier are transferred to another carrier. The transfer device provided in this example is suitable for transferring large quantities of workpieces 1 to be processed, and can realize intelligent adsorption transfer of the workpiece 1 to be processed, with high adsorption alignment accuracy, firm adsorption, high transfer efficiency, and high production efficiency.

[0061] In one example, the suction process of the suction nozzle to the workpiece 1 to be processed includes: first, the detection unit 30 is used to identify the marking point on the original carrier, the center point of the workpiece 1 to be processed and the center point of the suction nozzle; then, the moving unit 20 is controlled to move toward the workpiece 1 to be processed until the suction nozzle abuts against the workpiece 1 to be processed. At this time, the suction member 200 is first pressed downward, and then the elastic component 300 is used to buffer the contact stress generated between the suction member 200 and the workpiece 1 to be processed, and then the suction member 200 is pressed back to make the suction member 200 completely adhere to the surface of the workpiece 1 to be processed, ensuring that the suction nozzle and the workpiece 1 to be processed are in contact with each other. There will be no air leakage between the processed workpieces 1, ensuring the vacuum value of the two; then, the vacuum unit 10 is used for evacuation to generate an adsorption negative pressure between the adsorption component 200 and the workpiece 1 to be processed, and the workpiece 1 to be processed is firmly adsorbed on the suction nozzle; then, the marking point of another carrier is identified by the detection unit 30, and the transfer unit is controlled to move the suction nozzle to the corresponding position on the other carrier; finally, the vacuum unit 10 is controlled to stop operating, and the suction nozzle is transferred to the position of the next workpiece 1 to be processed through the transfer unit, and this process is repeated to achieve the transfer of multiple workpieces 1 to be processed.
