Description

Technical Field

[0001] This utility model relates to the field of activation equipment technology, and in particular to a multi-faceted adsorption device and a high-efficiency activation device. Background Technology

[0002] Automotive interior parts generally refer to components and materials such as partitions in the passenger compartment, door trim panels, dashboard assemblies, armrests, and carpets. Although interior parts are only auxiliary components, they play a role in vibration damping, heat insulation, sound absorption, and soundproofing. During the processing of interior products, activation equipment is used to heat-melt activate the adhesive materials to bond surface materials such as leather and fabrics to the substrate.

[0003] Traditional activation equipment has only a single work surface. Although a single work surface can hold multiple different products, the automotive series often has a large number of products. Due to the limitations of equipment size, a single work surface is not enough to cover all types of products. Therefore, after producing products on one side, the mold on the work surface can only be removed and replaced with a new mold. This disassembly and assembly process takes more than 1 hour, resulting in reduced production efficiency. At the same time, frequent mold changes lead to poor mold position repeatability. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the fact that traditional activation equipment in the prior art not only cannot achieve parallel operation of loading and unloading and activation processes, but also lacks workpiece buffering capacity, which forces the production line rhythm to be tied to the slowest process, resulting in low processing efficiency of interior products. Thus, a multi-faceted adsorption device and a high-efficiency activation equipment are provided.

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-faceted adsorption device, comprising:

[0006] A rotating mechanism includes: a frame, a drive unit, a rotating shaft, and a support assembly. The support assembly has rotating shafts at both ends along its axial direction. The rotating shafts are rotatably connected to the frame. The output end of the drive unit is connected to the rotating shaft. The support assembly has multiple adsorption surfaces on its periphery for adsorbing and fixing workpieces.

[0007] An adsorption mechanism includes a vacuum assembly, a multi-way valve, and a diverter tube. The vacuum assembly is connected to the multi-way valve. The number of diverter tubes is multiple and corresponds to the adsorption surface. One end of each diverter tube is connected to the multi-way valve, and the other end passes through a support assembly and extends to the adsorption surface.

[0008] In one embodiment of the present invention, the support assembly includes a bracket and side plates, wherein the number of side plates is at least three and they are respectively disposed on the periphery of the bracket.

[0009] In one embodiment of the present invention, the surface of the side plate is provided with a plurality of first flow channels and a plurality of second flow channels, the first flow channels and the second flow channels are intersected, and the intersection of the first flow channels and the second flow channels are interconnected.

[0010] In one embodiment of this utility model, the adsorption surface is disposed on the first side of the side plate, and a guide is connected to the second side of the side plate opposite to the first side. A suction cup is disposed at the end of the guide, and the two ends of the guide are respectively connected to the diverter pipe and the suction cup. The suction cup extends through the side plate to the first side of the side plate, and the air inlet of the suction cup is connected to the first flow channel and / or the second flow channel.

[0011] In one embodiment of this utility model, the side plate has a groove on the first side, the suction cup is embedded in the groove, the groove is connected to the first flow channel and the second flow channel, and the height of the air inlet of the suction cup is less than the height of the adsorption surface.

[0012] In one embodiment of this utility model, the air inlet of the suction cup is provided with a filter.

[0013] In one embodiment of this utility model, the frame is provided with a bearing seat, the rotating shaft is fixedly connected to the inner ring of the bearing seat, and the support assembly is rotatably connected to the frame through the rotating shaft and the bearing seat.

[0014] In one embodiment of the present invention, the vacuum assembly includes a vacuum pump, a vacuum tank, and a vacuum tube. The vacuum pump is connected to the vacuum tank and is used to maintain a vacuum inside the vacuum tank. The two ends of the vacuum tube are respectively connected to the vacuum tank and a multi-way valve.

[0015] In one embodiment of this utility model, the vacuum tube is further connected to a first control valve for controlling its on / off state, and the vacuum tank is provided with a second control valve for communicating with the outside world.

[0016] This utility model also discloses a high-efficiency activation device, including the aforementioned multi-faceted adsorption device.

[0017] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0018] The multi-faceted adsorption device described in this utility model uses a drive component to rotate a rotating shaft. A support component is rotatably connected to the frame via the rotating shaft. Multiple adsorption surfaces are provided around the support component. Negative pressure is provided through these adsorption surfaces to adsorb the interior products to be activated onto the periphery of the support component. Negative pressure is provided by a vacuum component, and the drive component controls the rotation angle of the support component, allowing for rapid switching to the target adsorption surface.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] Example

[0028] Reference Figures 1-5 As shown, the present invention provides a multi-faceted adsorption device, comprising:

[0029] A rotating mechanism includes: a frame 1, a drive component 16, a rotating shaft 13, and a support assembly 2. The support assembly 2 has rotating shafts 13 at both ends along its axial direction. The rotating shafts 13 are rotatably connected to the frame 1. The output end of the drive component 16 is connected to the rotating shaft 13. The support assembly 2 has multiple adsorption surfaces 21 on its periphery for adsorbing and fixing workpieces.

[0030] The adsorption mechanism includes a vacuum assembly, a multi-way valve, and a diverter tube 10. The vacuum assembly is connected to the multi-way valve. There are multiple diverter tubes 10, each corresponding to an adsorption surface 21. One end of each diverter tube 10 is connected to the multi-way valve, and the other end passes through the support assembly 2 and extends to the adsorption surface 21.

[0031] The multi-faceted adsorption device of this utility model drives the rotating shaft 13 to rotate via the driving component 16. The support component 2 is rotatably connected to the frame 1 via the rotating shaft 13. Multiple adsorption surfaces 21 are provided on the periphery of the support component 2. The adsorption surfaces 21 provide negative pressure to adsorb the interior product 15 to be activated onto the periphery of the support component 2. The vacuum component provides negative pressure, and the multi-way valve accurately distributes the airflow to ensure that the negative pressure of each adsorption surface 21 is uniform and stable, preventing the workpiece from falling off due to insufficient adsorption force. The driving component 16 controls the rotation angle of the support component 2, which can quickly switch to the target adsorption surface 21. It is suitable for automated production lines that require frequent adjustment of workpiece posture. Multiple adsorption surfaces 21 can work simultaneously or independently, and together with the rotating mechanism, they can adsorb the product 15 within a range of 270°, significantly improving the fixation efficiency in multi-station processing scenarios.

[0032] Reference Figures 1-3 As shown, the support component 2 includes a bracket and side plates 3. The number of side plates 3 is at least three and they are respectively arranged on the periphery of the bracket. The side plates 3 serve as carriers for the adsorption surface 21. Their number and angle configuration directly determine the multi-faceted adsorption capacity of the device. They form a triangular prism structure, which can sequentially adsorb three groups of products 15 for centralized processing. Alternatively, a dual-station configuration can be used. The first adsorption surface 21 is configured as a working surface for being pressed and heated for activation. The second adsorption surface 21 is configured as a feeding surface for synchronous feeding during processing. The third adsorption surface 21 is configured as a buffer surface to buffer one group of products 15.

[0033] Reference Figure 4As shown, the surface of the side plate 3 is provided with multiple first flow channels 18 and multiple second flow channels 19. The first flow channels 18 and second flow channels 19 are intersected and interconnected at their intersections. The two flow channels are orthogonally arranged to form a regular grid-like matrix. When the side plate 3 is rectangular, the grid cells are square, with the side length consistent with the channel spacing. Circular buffer cavities are machined at the flow channel intersections to balance the lateral and longitudinal airflow pressures and avoid local pressure drops caused by right-angle intersections; these also serve as temporary gas storage spaces to compensate for instantaneous airflow fluctuations in the suction cup 12 and maintain stable adsorption force. When a flow channel is blocked (e.g., due to debris accumulation), adjacent flow channels can bypass the airflow through their intersections, maintaining an overall negative pressure on the adsorption surface 21.

[0034] The adsorption surface 21 is disposed on the first side of the side plate 3. A guide member 11 is connected to the second side of the side plate 3 opposite to the first side. A suction cup 12 is disposed at the end of the guide member 11. The two ends of the guide member 11 are respectively connected to the diverter pipe 10 and the suction cup 12. The suction cup 12 extends through the side plate 3 to the first side of the side plate 3. The air inlet of the suction cup 12 is connected to the first flow channel 18 and / or the second flow channel 19. The guide member 11 has a hollow structure, and the suction cup 12 is disposed in the central area of ​​the adsorption surface 21.

[0035] Reference Figure 4 As shown, the side plate 3 has a groove 17 on the first side, and the suction cup 12 is embedded in the groove 17. The grooves 17 are all connected to the first flow channel 18 and the second flow channel 19. The height of the air inlet of the suction cup 12 is less than the height of the adsorption surface 21. The air inlet of the suction cup 12 is lower than the adsorption surface 21, so that the workpiece surface and the air inlet maintain a safe distance and avoid direct coverage of the air inlet causing blockage. The groove 17 connects the first and second flow channels 19, so that the suction cup 12 can simultaneously obtain airflow from the transverse and longitudinal flow channels. When one flow channel is partially blocked, the flow channel in the other direction can continue to maintain the adsorption force, improving the fault tolerance of the system.

[0036] Reference Figure 4 As shown, the air inlet of the suction cup 12 is equipped with a filter element 20. The filter element 20 can intercept particulate and fibrous impurities, such as leather scraps, that fall off the surface of the workpiece, preventing them from entering the flow channels, the conductive element 11, and the vacuum assembly. The filter element 20 has a porous structure. When the suction cup 12 adsorbs the workpiece, the airflow carrying impurities enters the filter element 20 from the air inlet. The impurities are intercepted by the filter element 20, and the airflow enters each flow channel through the pores. In addition, the porous structure of the filter element 20 acts as an airflow buffer layer, which can disperse the concentrated airflow at the air inlet, allowing the airflow to diffuse evenly to the first flow channel 18 and the second flow channel 19. This avoids uneven pressure on the adsorption surface 21 caused by excessively fast local airflow.

[0037] Reference Figure 5As shown, the frame 1 is equipped with a bearing housing 14, and the rotating shaft 13 is fixedly connected to the inner ring of the bearing housing 14. The support assembly 2 is rotatably connected to the frame 1 via the rotating shaft 13 and the bearing housing 14. The inner ring of the bearing housing 14 is fixedly connected to the rotating shaft 13. When the drive component 16, such as a servo motor or a stepper motor, starts, its output shaft is connected to the rotating shaft 13 via a coupling, driving the rotating shaft 13 to rotate. Since the rotating shaft 13 is rigidly fixed to the inner ring of the bearing, the inner ring of the bearing rotates synchronously with the rotating shaft 13, while the outer ring of the bearing remains stationary because it is fixed in the mounting seat. This transforms the friction mode of rotational motion from sliding friction to rolling friction, significantly reducing rotational resistance.

[0038] Reference Figures 1-2 As shown, the vacuum assembly includes a vacuum pump 7, a vacuum tank 4, and a vacuum tube 6. The vacuum pump 7 is connected to the vacuum tank 4 and is used to maintain a vacuum inside the vacuum tank 4. The two ends of the vacuum tube 6 are connected to the vacuum tank 4 and a multi-way valve, respectively. After the vacuum pump 7 starts, it draws gas from the vacuum tank 4 through the first connecting tube, gradually reducing the pressure inside the vacuum tank 4. The negative pressure is maintained by the volume buffer of the vacuum tank 4 until the vacuum pressure sensor detects that the vacuum level inside the tank has reached a set lower limit. This avoids a sudden drop in negative pressure due to the response delay of the vacuum pump 7, preventing frequent start-stop of the vacuum pump 7 and extending its service life. When the adsorption mechanism needs to work, such as switching to a certain adsorption surface 21, the solenoid valve of the branch corresponding to the multi-way valve opens, and the negative pressure inside the vacuum tank 4 is transmitted to the branch's diversion pipe 10 through the vacuum tube 6.

[0039] Reference Figures 1-2 The vacuum tube 6 is also connected to a first control valve 5 for controlling its on / off state, and the vacuum tank 4 is equipped with a second control valve 9 for communicating with the outside world. When the adsorption mechanism is working normally, the first control valve 5 is open, the vacuum tube 6 is open, and the negative pressure inside the vacuum tank 4 is transmitted to the multi-way valve through the vacuum tube 6, and then distributed to each adsorption surface 21. The vacuum pump 7 is connected to the vacuum tank 4 through a pump pipe 8, and the second control valve 9 is located on the vacuum tank 4. By opening or closing the second control valve 9, the communication or closure state between the space inside the vacuum tank 4 and the outside world can be controlled. Both the first and second sub-valve are solenoid valves.

[0040] This embodiment also discloses a high-efficiency activation device, including the multi-faceted adsorption device described above.

[0041] The high-efficiency activation equipment disclosed in this embodiment takes the activation of adhesives in automotive interior parts, such as leather and fabric composites, during hot melting as an application scenario. By integrating the multi-faceted adsorption device, it achieves multi-faceted adsorption, posture switching, and continuous activation processing of the workpiece, significantly improving production efficiency and activation quality. The workflow of the high-efficiency activation equipment can be divided into five stages: loading, adsorption, rotation, activation hot melting, and unloading, realizing efficient, stable, and intelligent production of multi-faceted activation of interior products.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
