Description

Technical Field

[0001] The present 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 and is mainly responsible for cutting and trimming the required materials. According to different application scenarios and technical characteristics, the blanking mechanism can be divided into a manual blanking mechanism, a mechanical blanking mechanism, a numerical control blanking mechanism, and an automated robot blanking mechanism.

[0003] For example, a Chinese patent application with a publication number of CN118663530A discloses a dispensing and picking nozzle device, which relates to the technical field of dispensing machine accessories. It includes a support assembly and a nozzle assembly installed inside the support assembly, and also includes a bellows 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 bearing platform assembly is installed outside the support assembly. In the present invention, by setting the nozzle assembly, a bellows 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 realize the up and down adjustment of the position of the bellows nozzle. Compared with the traditional gravity and spring nozzles, the electromagnet and the magnetic plate can more stably control the position of the bellows nozzle, thereby ensuring the stability of the nozzle when adsorbing materials.

[0004] Another example is a Chinese patent application with a publication number of CN117373986A, which discloses a nozzle for the loading and unloading mechanism of a chip testing mechanism, relating to the technical field of chip testing. It includes a mechanism connecting frame and a nozzle assembly. Support frame groups are installed on the left and right sides of the mechanism connecting frame, and a buffer assembly is vertically arranged at the lower end of the support frame groups. An adjusting mechanism is installed at the center of the bottom of the mechanism connecting frame, and the nozzle assembly is installed on the left and right sides of the adjusting mechanism. A cleaning assembly is connected to the side of the nozzle assembly away from the adjusting mechanism. For this nozzle of the loading and unloading mechanism of the chip testing mechanism, the combined use of the support frame groups and the buffer assembly enables the device to have structural buffering with the working table surface when operating in the vertical direction. At the same time, in cooperation with the telescopic connecting pipe and the buffer spring, the telescopic nozzle with telescopic properties can be effectively protected by structural buffering, avoiding excessive structural operation stroke when loading and unloading the chip in the vertical direction, which may damage some structures, and also protecting the chip itself from external force damage.

[0005] Most traditional processes use grippers for blanking, which are prone to blanking side tipping and product extrusion. In the blanking mechanism using nozzles, the installation form of the nozzles is single, and the suction force when the nozzles adsorb products cannot be controlled, affecting the quality of the products.

[0032] Such as Figure 1 , Figure 9 And Figure 10As shown in the figure, the present invention provides a blanking mechanism, including a suction nozzle 11 and an installation structure. The suction nozzle 11 is movably installed on the installation structure. The installation structure includes an installation base 6 and a connecting ring 10. The installation base 6 and the connecting ring 10 are integrally welded. The suction nozzle 11 is connected to the connecting ring 10. The top end of the suction nozzle 11 is integrally welded with a threaded connection ring 16. In order to install various different models of suction nozzles, the bottom end of the connecting ring 10 is provided with an outer layer installation hole 14 and an inner layer installation hole 15. Different models of suction nozzles 11 are installed in both the outer layer installation hole 14 and the inner layer installation hole 15. Specifically, the threaded connection ring 16 is threadedly connected to the outer layer installation hole 14 and the inner layer installation hole 15. The distance between the outer layer installation hole 14 and the inner layer installation hole 15 is the distance between the threaded connection rings 16 of two adjacent models of suction nozzles.

[0033] Embodiment 1

[0034] As Figure 10 shown, two different models of suction nozzles 11 installed on the outer layer installation hole 14 and the inner layer installation hole 15 are assembled and installed. Specifically, the larger model of suction nozzle can be directly sleeved on the smaller model of suction nozzle in sequence, without the need to replace different suction nozzles multiple times. The top ends of the suction nozzles 11 are respectively threadedly connected to the outer layer installation hole 14 and the inner layer installation hole 15 to ensure the reliable installation of the suction nozzles 11.

[0035] Embodiment 2

[0036] On the basis of Embodiment 1, in order to ensure that the stable adsorption of parts by the suction nozzle is not affected when the suction nozzles are sleeved and installed, as Figure 10 shown, the suction nozzle 11 is evenly provided with air holes 17. The two different models of suction nozzles 11 on the outer layer installation hole 14 and the inner layer installation hole 15 are sleeved, and the positions of the air holes 17 on the two different models of suction nozzles 11 correspond to facilitate the flow of gas so as to smoothly suck parts.

[0037] Furthermore, as Figure 6 shown, an air suction cavity 32 is provided inside the suction nozzle 11, and a gas flow rate control component is installed in the air suction cavity 32.

[0038] As Figures 6 - 8As shown in the figure, 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. An installation hole 31 is provided on the connecting ring 10. The fixed shaft 30 passes through the installation hole 31 and extends into the suction cavity 32. The fixed shaft 30 and the suction cavity 32 are coaxial. A rubber block 33 is movably sleeved on the fixed shaft 30. When gas is injected into the suction cavity 32, 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 cavity 32. When the adsorption force injected into the suction cavity 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 cavity 32 blocked by the rubber block 33 is unblocked, and the adsorption force flows through the ventilation gap 36 to the part, and the part is stably adsorbed on the suction nozzle 11.

[0039] In order to adjust the adsorption force at various positions in the suction cavity 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 arranged in a circumferential pattern on the fixed circular plate 29. By providing the through holes 25, it is convenient for the gas in the mounting seat 6 to flow. At the same time, by installing the fixed circular plate 29, the resistance of the adsorption force in the mounting seat 6 is increased, that is, the speed is slower through the fixed circular plate 29. In order to further reduce the upward movement speed of the rubber block 33, that is, to reduce the adsorption speed at 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 a middle collar 28 are sleeved on the fixed shaft 30. The middle collar 28 is located between the top collar 26 and the rubber block 33. The top collar 26 is located in the mounting seat 6. Specifically, the top of the mounting seat 6 absorbs the upward gas. The gas enters the suction cavity 32 from the bottom end of the suction cavity 32, passes through the rubber block 33, the installation hole 31 in sequence and enters the mounting seat 6, and passes through the top collar 26 and the through holes 25. When the suction force at the top of the mounting seat 6 is large enough, the gas pushes the rubber block 33 away. At this time, the gas continues to move upward from the ventilation gap 36. Since the bottom of the suction cavity 32 is unblocked, the suction force at the bottom of the suction cavity 32 changes from small to large. During the change of the suction force, 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 larger, the suction nozzle 11 stably sucks the part.

[0040] The diameter of the top collar 26 is greater than the maximum distance between 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 position where the top collar 26 blocks the through holes 25, so that the gas volume in the suction cavity 32 is constant, thereby stably adsorbing the workpiece.

[0041] Furthermore, a boss 34 is integrally welded to the bottom end of the fixed shaft 30 to prevent the rubber block 33 from falling due to its own gravity and blocking the bottom of the suction cavity 32 after the suction force is withdrawn, resulting in too large a blocking force and affecting the next movement of the rubber block 33.

[0042] To protect the contact surface between the part and the nozzle 11, a rubber body 35 is installed at the bottom end of the nozzle 11. The cross-section of the rubber body 35 is a conical surface, which can effectively protect the surface of the part while facilitating air circulation.

[0043] Embodiment Three

[0044] Based on the above Embodiment Two, in order to achieve multiple installation methods of the nozzle 11, as Figures 1 - 3 shown, the installation structure is installed on the movable part. The movable part includes a universal sleeve 3. The mounting seat 6 is rotatably connected to the universal sleeve 3. The axis of the universal sleeve 3 and the axis of the mounting seat 6 are always perpendicular. That is, the angle of the nozzle 11 can be adjusted through the mounting seat 6 and the universal sleeve 3. The mounting seat 6 rotates relative to the universal sleeve 3. At the same time, another way to adjust the angle of the nozzle 11 is provided. A middle shaft body 7 is rotatably sleeved in the universal sleeve 3. By rotating the universal sleeve 3 relative to the middle shaft body 7, the mounting seat 6 and the nozzle 11 are driven to rotate together. End fixing plates 2 are installed at both ends of the middle shaft body 7. A connecting body 8 is connected to the rear end of the end fixing plate 2. 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. The nozzle 11 can be installed in different mechanical equipment through the front end panel 4.

[0045] When the angle of the nozzle 11 is adjusted by rotating the universal sleeve 3 relative to the middle shaft body 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 Figure 4 and Figure 5 shown, a positioning component is installed between the universal sleeve 3 and the middle shaft body 7. The positioning component includes a positioning block 20. A reset cavity 18 is opened in the universal sleeve 3. A card slot 19 is reserved in the reset cavity 18. A plurality of outer positioning holes 21 are evenly opened on the outer circle of the middle shaft body 7. The positioning block 20 includes an arc body 22. 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. One end of the reset spring 27 is installed in the reset cavity 18. The maximum linear distance from the arc body 22 to the inner convex block 23 is equal to the minimum diameter of the reset cavity 18. Specifically, after the universal sleeve 3 rotates relative to the middle shaft body 7, the positioning block 20 retracted in the reset cavity 18 is pulled outwards, and the outer convex block 24 is aligned with the outer positioning hole 21, and the inner convex block 23 is aligned with the card slot 19. Apply force to press the outer convex block 24 into the outer positioning hole 21 and the inner convex block 23 into the card slot 19 to complete the position limitation of the universal sleeve 3 and the middle shaft body 7, preventing the position of the nozzle 11 from changing due to gas flow.

[0046] Embodiment Four

[0047] On the basis of the above Embodiment 3, in order to make the nozzle 11 applicable to various forms of installation, such as Figures 1 - 3 As shown, one end of the front panel 4 is connected to the rear panel 12. A positioning threaded hole 13 is provided between the front panel 4 and the rear panel 12. Two cross beams 5 are clamped between the front panel 4 and the rear panel 12. By installing or disassembling the bolt structure in the positioning threaded hole 13, the position of the nozzle 11 on the cross beam 5 can be adjusted. Mounting rods 1 are installed at both ends of the cross beam 5. The nozzle 11 and the mechanical equipment are installed using the mounting rods 1. The cross 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 nozzle 11 of the corresponding size into the outer installation hole 14 or the inner installation hole 15 (when using a large-sized nozzle, directly assemble the large-sized nozzle on the small-sized nozzle in sequence; when using a small-sized nozzle, directly remove the large-sized nozzle). Adjustment of the angle: The universal joint sleeve 3 rotates relative to the middle shaft body 7. After the rotation is completed, pull the positioning block 20 retracted in the reset cavity 18 outwards, apply force to press the outward convex block 24 into the outer positioning hole 21, and press the inward convex block 23 into the card slot 19. Working: The top of the mounting seat 6 absorbs the upward gas. The gas enters the suction cavity 32 from the bottom end of the suction cavity 32, passes through the rubber block 33 and the mounting hole 31 in sequence and enters the mounting seat 6. The gas 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 open the rubber block 33, and the gas continues to move upwards at the ventilation gap 36, and the bottom of the suction cavity 32 is unblocked. During the process, when the suction force is small, the parts are slowly adjusted to the optimal adsorption position, and the parts are moved closer to the nozzle 11. The middle collar 28 and the top collar 26 move upwards. During the process, the suction force gradually increases until the position where the top collar 26 blocks the through hole 25, so that the amount of gas in the suction cavity 32 is constant, and the nozzle 11 stably sucks the parts.

Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
