Description

Technical Field

[0001] This utility model relates to the field of vacuum material suction equipment technology, specifically a double-plane bonding rotary vacuum material suction module. Background Technology

[0002] In the field of automated production, vacuum material handling modules are core components for the pick-up and transfer of materials such as sheets and granules, and are widely used in mounting, sorting, and other scenarios. Currently, most of these vacuum material handling modules use air slip rings. Air slip rings require the integration of complex parts such as precision rolling bearings and multi-layer sealing rings, resulting in high manufacturing and procurement costs. Furthermore, their three-dimensional cylindrical shape requires a large radial and axial installation space, making them difficult to adapt to miniaturized automated equipment. After long-term use, the air slip ring bearings are prone to wear, leading to a decrease in air path alignment accuracy and vacuum leakage, which in turn reduces the material pick-up success rate and causes production line downtime losses. Utility Model Content

[0003] In order to overcome the shortcomings of existing technical solutions, this utility model provides a double-plane bonding rotary vacuum suction module, which can effectively solve the problems mentioned in the background technology.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A double-plane bonding rotary vacuum suction module includes a vacuum branching component, a vacuum conversion fixing layer, a vacuum conversion rotating layer, a material suction station component, and a vacuum outlet.

[0006] The vacuum branching assembly is located above the vacuum conversion fixing layer and is connected to the vacuum conversion fixing layer. It is used to branch and distribute the vacuum path.

The vacuum conversion rotating layer can rotate relative to the vacuum conversion fixing layer around its central axis. The material suction station assembly is connected to the vacuum conversion rotating layer and is used to realize the material suction action.

[0007] The vacuum branch assembly is used to connect with an external vacuum source or gas path system to form the gas path terminal of the vacuum path.

[0022] 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.

[0023] like Figure 1-3 As shown, this utility model provides a double-plane bonding rotary vacuum suction module, including a vacuum branching component, a vacuum conversion fixing layer 3, a vacuum conversion rotating layer 4, a material suction station component 2, and a vacuum outlet 5.

[0024] The external vacuum source (or gas path system) is first connected to the vacuum branching assembly located above the vacuum conversion fixing layer 3. This assembly, through multiple branching gas path interfaces, evenly disassembles the single gas path of the external vacuum source into multiple branches, and seals them one by one with the gas path ports of the vacuum conversion fixing layer 3. This step completes the "preliminary allocation" of the vacuum path, ensuring that the vacuum can be delivered to each gas path node of the fixing layer as needed, and preparing for the subsequent gas path conversion.

[0025] The vacuum branching assembly is located above the vacuum conversion fixing layer 3 and is connected to the vacuum conversion fixing layer 3. It is used to branch and distribute the vacuum passage. The vacuum conversion rotating layer 4 is attached to the vacuum conversion fixing layer 3 in an upper and lower plane. The vacuum conversion rotating layer 4 can rotate relative to the vacuum conversion fixing layer 3 around its central axis. The material suction station assembly 2 is connected to the vacuum conversion rotating layer 4 and is used to realize the material suction action.

[0026] Simultaneously with the distribution of the vacuum passage, the downward pressure counterweight structure 1 begins to operate. This structure is specifically an elastic pressure-fitting structure (such as a spring pressure-fitting assembly). Through the preload of the elastic element, it applies continuous and stable pressure to the upper and lower vacuum conversion fixing layer 3 and vacuum conversion rotating layer 4. This structure eliminates gaps between the two layers caused by processing errors and long-term wear, preventing vacuum leakage at its source, ensuring the sealing performance of the gas path, and providing a foundation for the stable conduction of the vacuum passage.

[0027] The vacuum branch assembly is used to connect with an external vacuum source or gas path system to form the gas path terminal of the vacuum path. The vacuum conversion rotating layer 4 rotates by a fixed angle each time, so that the upper and lower gas path ports of the vacuum conversion rotating layer 4 and the vacuum conversion fixed layer 3 are aligned one by one.

[0028] According to the cycle time requirements of material absorption, the vacuum conversion rotating layer 4 rotates around the central axis of the vacuum conversion fixed layer 3. Its rotation angle is strictly set as the "central angle between two adjacent gas ports on the rotating layer"—for example, if the rotating layer has 6 gas ports evenly distributed, and the central angle between adjacent gas ports is 60°, then the rotating layer rotates precisely by 60° each time. After rotating into position, the gas ports of the rotating layer are precisely aligned with the gas ports of the fixed layer, so that the vacuum distribution component distributes the vacuum path to the fixed layer. Through the alignment interface of the "fixed layer-rotating layer", the gas path system of the rotating layer is seamlessly connected, completing the "dynamic conversion" of the vacuum path.

[0029] The material suction station assembly 2 is directly connected to the vacuum conversion rotating layer 4, and multiple stations are evenly distributed along the circumference of the rotating layer. The vacuum suction cup 6 of each station is connected to the air passage of the rotating layer through a sealed air passage pipe, achieving "zero gap" connection. When the vacuum passage is connected to the rotating layer, a stable negative pressure is quickly formed in the vacuum suction cup 6, thereby adsorbing the material to be suctioned (such as flakes, granules, and irregularly shaped parts). At the same time, the vacuum outlet 5 serves as the exhaust channel at the end of the air passage, balancing the air pressure in the system in real time, maintaining the stability of the negative pressure, and ensuring that the material will not fall off during the transfer process, thus completing the entire material suction action.

[0030] Furthermore, it also includes a pressure counterweight structure 1, which is connected to the vacuum conversion fixing layer 3 and is used to press and fix the planar fit between the vacuum conversion fixing layer 3 and the vacuum conversion rotating layer 4.

[0031] Traditional air slip rings require the integration of complex parts such as precision rolling bearings, multi-layer sealing rings, and conductive rings, which makes the manufacturing process difficult and the procurement cost high; moreover, air slip rings are three-dimensional cylindrical structures, requiring a large amount of radial and axial installation space.

[0032] This embodiment adopts a design of upper and lower plane bonding of "vacuum conversion fixed layer 3 and rotating layer", which reduces the number of parts and the requirements for plane machining accuracy, thus directly reducing manufacturing costs. At the same time, the two-layer components adopt an upper and lower stacked design, with a small axial height, which greatly reduces the overall space occupied by the equipment and adapts to the installation requirements of miniaturized automated equipment.

[0033] Furthermore, the vacuum branching assembly includes multiple branching gas path interfaces, and each branching gas path interface is connected to a corresponding gas path port of the vacuum conversion fixing layer 3.

[0034] Furthermore, the material suction station component 2 is provided in multiple ways, and the multiple material suction station components 2 are evenly distributed along the circumference of the vacuum conversion rotating layer 4.

[0035] Multiple workstations are evenly distributed along the circumference of the rotating layer. Based on the principle of symmetry in circular motion, the rotation path and vacuum conduction time of each workstation are completely consistent, enabling continuous operation of "rotation-suction-transfer". For example, the module with 6 workstations can rotate 60° each time to simultaneously complete the material suction of one workstation and the material transfer of another workstation.

[0036] Furthermore, the fixed angle of each rotation of the vacuum conversion rotating layer 4 is the angle corresponding to the central angle between two adjacent air inlets on the vacuum conversion rotating layer 4.

[0037] Based on the principle of mechanical angle positioning, the design of "rotation angle = central angle of adjacent air passages" ensures precise alignment of the air passages after each rotation. Compared to traditional air slip rings where air passage misalignment is caused by bearing wear, this embodiment achieves high air passage alignment accuracy and vacuum passage conductivity through rigid plane contact and angle limiting. This avoids vacuum leakage caused by air passage misalignment, ensures high material pick-up success rate, and reduces downtime losses on the production line due to material spillage.

[0038] Furthermore, the pressure counterweight structure 1 is an elastic pressure-fitting structure, used to provide continuous bonding pressure between the vacuum conversion fixed layer 3 and the vacuum conversion rotating layer 4.

[0039] The elastic pressure-fitting structure (such as a spring) is based on the "pressure self-compensation" characteristic of material mechanics, which can continuously apply stable bonding pressure during the long-term use of the module, eliminating the problem of increased bonding gap caused by component wear and temperature changes. Compared with the planar bonding structure without pressure-fitting structure, the air circuit sealing rate and service life of this embodiment are significantly improved.

[0040] Furthermore, the material suction station assembly 2 includes a vacuum suction cup 6, which is sealed to the air passage interface of the vacuum conversion rotating layer 4 via an air passage pipe.

[0041] The multi-interface design of the vacuum distribution assembly can adapt to external vacuum sources of different specifications. The vacuum suction cup 6 supports quick replacement (via snap-fit / threaded connection), allowing for the replacement of suction cups of corresponding sizes / shapes for different materials (such as 0.1mm thin sheets, 5mm granules, and irregularly shaped plastic parts). Each component adopts a detachable connection (bolted connection), allowing for the replacement of damaged parts without disassembling the entire module. It is suitable for various material suction scenarios, and the maintenance time is shorter than that of traditional air slip ring structures, reducing equipment downtime costs.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
