Description

Technical Field

[0001] The invention belongs to the technical field of mechanical equipment, and particularly relates to a blanking mechanism. Background Art

[0002] The blanking mechanism plays a crucial role in mechanical design, primarily responsible for cutting and trimming the required materials. Depending on the application scenario and technical characteristics, blanking mechanisms can be categorized as manual, mechanical, CNC, and automated robotic.

[0003] For example, a Chinese invention patent application with application publication number CN118663530A discloses a dispensing nozzle device, which relates to the technical field of dispensing machine accessories, including a support assembly and a nozzle assembly installed inside the support assembly, and also includes an accordion nozzle installed at the bottom end of the nozzle assembly, a conductive assembly is installed between the nozzle assembly and the support assembly, and a base assembly is installed on the outside of the support assembly. The present invention is provided with a nozzle assembly, and an accordion nozzle for sucking materials is provided at the bottom end of the nozzle assembly. By installing an electromagnet and a magnetic plate at the bottom end of the nozzle assembly, the electromagnet and the magnetic plate cooperate to achieve the up and down adjustment of the position of the accordion nozzle. Compared with the traditional center of gravity and spring nozzle, the electromagnet and the magnetic plate can more stably control the position of the accordion nozzle, thereby ensuring the stability of the nozzle when sucking materials.

[0004] For another example, a Chinese invention patent application with application publication number CN117373986A discloses a nozzle for a loading and unloading mechanism of a chip testing mechanism, which relates to the field of chip testing technology and includes a mechanism connecting frame and a nozzle assembly. The left and right sides of the mechanism connecting frame are equipped with a support frame group, and a buffer assembly is vertically provided at the lower end of the support frame group. An adjustment mechanism is installed at the bottom center of the mechanism connecting frame. The nozzle assembly is installed on the left and right sides of the adjustment mechanism, and a cleaning assembly is connected to the side of the nozzle assembly away from the adjustment mechanism. The nozzle of the loading and unloading mechanism of a chip testing mechanism, through the combined use of the support frame group and the buffer assembly, acts as a structural buffer between the device and the work surface when operating in the vertical direction. At the same time, with the telescopic connecting tube and the buffer spring, the telescopic nozzle with telescopic function can obtain effective structural buffer protection, thereby avoiding excessive structural operation stroke and thus damaging part of the structure when loading and unloading the chip in the vertical direction, and also protecting the chip itself from external force damage.

[0005] Traditional processes mostly use clamps for unloading, which is prone to material tipping and product squeezing. In the unloading mechanism using a suction nozzle, the installation form of the nozzle is single, and the suction force of the nozzle when adsorbing the product cannot be controlled, affecting the quality of the product.

DETAILED DESCRIPTION

[0032] like Figure 1 、 Figure 9 and Figure 10As shown, the present invention provides a feeding mechanism, including a suction nozzle 11 and a mounting structure, the suction nozzle 11 is movably mounted on the mounting structure, the mounting structure includes a mounting seat 6 and a connecting ring 10, the mounting seat 6 and the connecting ring 10 are welded as one body, the suction nozzle 11 and the connecting ring 10 are connected, and a threaded connecting ring 16 is welded as one body on the top of the suction nozzle 11. In order to be able to install a variety of different types of suction nozzles, an outer mounting hole 14 and an inner mounting hole 15 are provided at the bottom end of the connecting ring 10, and different types of suction nozzles 11 are installed in the outer mounting hole 14 and the inner mounting hole 15. Specifically, the threaded connecting ring 16 is threadedly connected to the outer mounting hole 14 and the inner mounting hole 15. The distance between the outer mounting hole 14 and the inner mounting hole 15 is the distance between the threaded connecting rings 16 of two suction nozzles of similar models.

[0033] Example 1

[0034] like Figure 10 As shown, two different types of suction nozzles 11, one installed on the outer mounting hole 14 and the other installed on the inner mounting hole 15, are assembled and installed. Specifically, the larger type of suction nozzle can be directly installed on the smaller type of suction nozzle in sequence without having to replace different suction nozzles multiple times. The top end of the suction nozzle 11 is threadedly connected to the outer mounting hole 14 and the inner mounting hole 15 respectively to ensure that the suction nozzle 11 is reliably installed.

[0035] Example 2

[0036] On the basis of the first embodiment, in order to ensure that the nozzle sleeve does not affect its stable adsorption of parts during installation, such as Figure 10 As shown, air holes 17 are evenly opened on the suction nozzle 11, and two different types of suction nozzles 11 on the outer mounting hole 14 and the inner mounting hole 15 are connected, and the positions of the air holes 17 on the two different types of suction nozzles 11 correspond to each other, which is convenient for the circulation of gas so that the parts can be sucked smoothly.

[0037] Further, if Figure 6 As shown, a suction cavity 32 is provided in the suction nozzle 11 , and a gas flow rate control component is installed in the suction cavity 32 .

[0038] like Figure 6-Figure 8As shown, the gas flow rate control component includes a rubber block 33 and a fixed shaft 30. The fixed shaft 30 is fixedly installed in the mounting seat 6. A mounting hole 31 is opened on the connecting ring 10. The fixed shaft 30 extends through the mounting hole 31 to the suction chamber 32. The fixed shaft 30 and the suction chamber 32 are coaxial. A rubber block 33 is movably sleeved on the fixed shaft 30. Gas is injected into the suction chamber 32, and the rubber block 33 moves upward along the fixed shaft 30, so that there is a ventilation gap 36 between the bottom end of the rubber block 33 and the suction chamber 32. When the adsorption force injected into the suction chamber 32 is large enough, the adsorption force sucks the rubber block 33, causing the rubber block 33 to move upward. At this time, the lower half of the suction chamber 32 blocked by the rubber block 33 is unblocked, and the adsorption force flows to the part through the ventilation gap 36, stably adsorbing the part on the suction nozzle 11.

[0039] In order to adjust the size of the adsorption force at various locations in the suction chamber 32, a fixed circular plate 29 is fixedly installed in the mounting seat 6. A plurality of through holes 25 are provided on the fixed circular plate 29. The through holes 25 are circumferentially arranged on the fixed circular plate 29. The through holes 25 are provided to facilitate the circulation of gas in the mounting seat 6. At the same time, the resistance to the adsorption force in the mounting seat 6 is increased by installing the fixed circular plate 29, that is, the speed of the fixed circular plate 29 is slow. In order to further reduce the upward movement speed of the rubber block 33, that is, to reduce the adsorption speed of the bottom of the suction nozzle 11, the fixed shaft 30 is installed at the bottom end of the fixed circular plate 29. A top collar 26 and an intermediate collar 28 are sleeved on the fixed shaft 30. The intermediate collar 28 is located between the top collar 26 and the rubber Between the rubber blocks 33, the top collar 26 is located in the mounting seat 6. Specifically, the top of the mounting seat 6 absorbs upward gas, and the gas enters the suction chamber 32 from the bottom end of the suction chamber 32, passes through the rubber block 33 and the mounting hole 31 in turn, enters the mounting seat 6, and passes through the top collar 26 and the through hole 25. When the suction force at the top of the mounting seat 6 is large enough, the gas pushes away the rubber block 33. At this time, the gas continues to move upward from the ventilation gap 36. Since the bottom of the suction chamber 32 is unblocked, the suction force at the bottom of the suction chamber 32 changes from small to large. During the process of suction force change, when the suction force is small, the part is slowly adjusted to the optimal adsorption position, and the part is moved closer to the suction nozzle 11. When the suction force becomes large, the suction nozzle 11 stably absorbs the part.

[0040] The diameter of the top collar 26 is larger than the maximum distance between the two through holes 25 on the same axis of the fixed circular plate 29. During the upward movement of the rubber block 33, the middle collar 28 and the top collar 26 move upward until the top collar 26 blocks the through hole 25, so that the amount of gas in the suction chamber 32 is constant, thereby stably adsorbing the workpiece.

[0041] Furthermore, a boss 34 is integrally welded to the bottom of the fixed shaft 30 to prevent the rubber block 33 from blocking the bottom of the suction chamber 32 due to its own gravity after the suction force is removed, causing the blocking force to be too large and affecting the next movement of the rubber block 33.

[0042] In order to protect the contact surface between the part and the suction nozzle 11, a rubber body 35 is installed at the bottom end of the suction nozzle 11. The cross section of the rubber body 35 is a conical surface, which facilitates air circulation and can effectively protect the surface of the part.

[0043] Example 3

[0044] On the basis of the above embodiment 2, in order to realize the multiple installation modes of the nozzle 11, as shown in FIG. Figure 1-Figure 3 As shown, the mounting structure is installed on the movable part, and the movable part includes a universal sleeve 3, a mounting seat 6 and a universal sleeve 3 rotatably connected, and the axis of the universal sleeve 3 and the axis of the mounting seat 6 are always perpendicular, that is, the angle of the suction nozzle 11 can be adjusted by the mounting seat 6 and the universal sleeve 3, and the mounting seat 6 rotates relative to the universal sleeve 3. At the same time, another way to adjust the angle of the suction nozzle 11 is provided, and an intermediate shaft body 7 is provided in the universal sleeve 3. The universal sleeve 3 rotates relative to the intermediate shaft body 7, thereby driving the mounting seat 6 and the suction nozzle 11 to rotate together, and end fixing plates 2 are installed at both ends of the intermediate shaft body 7, and the rear end of the end fixing plate 2 is connected to a connecting body 8, and a side extension plate 9 is installed at the other end of the connecting body 8. A front end panel 4 is integrally formed between the two side extension plates 9, and the suction nozzle 11 can be installed in different mechanical equipment through the front end panel 4.

[0045] When the angle adjustment of the nozzle 11 is achieved by rotating the universal sleeve 3 relative to the intermediate shaft 7, in order to facilitate the reliability of the rotation of the universal sleeve 3, that is, the accuracy of the angle adjustment of the nozzle 11, as shown in FIG. Figure 4 and Figure 5 As shown, a positioning component is installed between the universal sleeve 3 and the intermediate shaft body 7, and the positioning component includes a positioning block 20. A reset cavity 18 is opened in the universal sleeve 3, and a card slot 19 is reserved in the reset cavity 18. A plurality of external positioning holes 21 are evenly opened on the outer ring of the intermediate shaft body 7. The positioning block 20 includes an arc body 22, and an inner convex block 23 and an outer convex block 24 are installed at the bottom end of the arc body 22. The inner convex block 23 is located in the card slot 19, and the outer convex block 24 is located in the outer positioning hole 21. A reset spring 27 is also installed at one end of the arc body 22, and one end of the reset spring 27 is installed In the reset cavity 18, the maximum straight-line distance from the arc body 22 to the inner protrusion 23 is equal to the minimum diameter of the reset cavity 18. Specifically, after the universal sleeve 3 is rotated relative to the intermediate shaft body 7, the positioning block 20 retracted in the reset cavity 18 is pulled outward, and the outer protrusion 24 is aligned with the outer positioning hole 21, and the inner protrusion 23 is aligned with the slot 19. Force is applied to press the outer protrusion 24 into the outer positioning hole 21, and the inner protrusion 23 into the slot 19, thereby completing the position limitation of the universal sleeve 3 and the intermediate shaft body 7 and preventing the suction nozzle 11 from changing its position due to gas flow.

[0046] Example 4

[0047] On the basis of the above embodiment 3, in order to make the nozzle 11 applicable to various installation forms, such as Figure 1-Figure 3 As shown, one end of the front panel 4 is connected to the rear panel 12, and a positioning threaded hole 13 is provided between the front panel 4 and the rear panel 12. Two beams 5 are clamped between the front panel 4 and the rear panel 12. By installing or removing the bolt structure in the positioning threaded hole 13, the position of the suction nozzle 11 on the beam 5 can be adjusted. Mounting rods 1 are installed at both ends of the beam 5. The mounting rods 1 are used to install the suction nozzle 11 and the mechanical equipment. The beam 5 is a telescopic rod, which is convenient for adjusting the installation size and has a wide range of applications.

[0048] The working principle of the present invention is as follows: Installation: Screw the suction nozzle 11 of corresponding size into the outer mounting hole 14 or the inner mounting hole 15 (when using a large-sized suction nozzle, directly assemble the large-sized suction nozzle on the small-sized suction nozzle in sequence, and when using a small-sized suction nozzle, directly remove the large-sized suction nozzle). Adjust the angle: The universal sleeve 3 rotates relative to the intermediate shaft 7. After the rotation is completed, the positioning block 20 retracted in the reset cavity 18 is pulled outward, and force is applied to press the outer protrusion 24 into the outer positioning hole 21, and the inner protrusion 23 into the card groove 19. Working: The top of the mounting seat 6 absorbs the upward gas, and the gas enters the suction cavity 32 from the bottom end. The air cavity 32 passes through the rubber block 33 and the mounting hole 31 in sequence and enters the mounting base 6. The gas passes through the top collar 26 and the through hole 25. When the suction force at the top of the mounting base 6 is large enough, the gas pushes the rubber block 33 away, and the gas continues to move upward from the ventilation gap 36, and the bottom of the suction cavity 32 is unblocked. During the process, when the suction force is small, the part is slowly adjusted to the optimal adsorption position, and the part is moved closer to the suction nozzle 11. The middle collar 28 and the top collar 26 move upward. During the process, the suction force gradually increases until the top collar 26 blocks the through hole 25, so that the amount of gas in the suction cavity 32 is constant, and the suction nozzle 11 stably absorbs the part.
