Description

Technical Field

[0001] This utility model relates to the field of vacuum suction cup fixture technology, and in particular to a splicing vacuum suction cup fixture. Background Technology

[0002] Vacuum grippers are commonly used mechanical devices for handling various parts. Due to their advantages of quick gripping and quick release, they are widely used in automated production lines.

[0003] Vacuum suction devices generally consist of a mounting shell and a suction cup body. The mounting shell is usually machined by hollowing out a sheet of material, leaving the four walls intact to accommodate the vacuum generating components. This manufacturing method generates a large amount of metal shavings, resulting in material waste. Furthermore, hollowing out the sheet material leads to a long processing cycle, low production efficiency, and the one-piece molding of the mounting shell means that its size cannot be changed as needed during subsequent use, resulting in low applicability.

[0004] Therefore, it is necessary to propose a technical means to solve the above-mentioned defects. Utility Model Content

[0028] Please see Figures 1 to 9A modular vacuum suction cup 20 fixture includes a mounting housing 10 and a vacuum suction cup 20 connected to the mounting housing 10. The mounting housing 10 includes an upper cover plate 101, a lower cover plate 102, and side plate 103 units mounted on the upper cover plate 101 and the lower cover plate 102. The side plate 103 assembly includes four side plates 103 arranged sequentially from end to end, and a transition block 104 mounted between two adjacent side plates 103 for connecting the two side plates 103. The upper and lower parts of the side plates 103 are respectively provided with first connecting holes 105 for connecting the upper cover plate 101 and the lower cover plate 102. The upper cover plate 101 and the lower cover plate 102 are provided with second connecting holes 106 corresponding to the first connecting holes 105.

[0029] Specifically, in this embodiment, in the assembled state, the first connecting hole 105 and the second connecting hole 106 are aligned and connected by bolts, so that the four side plates 103 and the adapter can be stably connected between the upper cover plate 101 and the lower cover plate 102. At the same time, since the four side plates 103 are arranged end to end, the four side plates 103 surround to form a mounting cavity for installing the vacuum generating assembly 30. Further, in this embodiment, the four side plates 103 surround to form a square mounting cavity. Further, the vacuum generating assembly 30 is used to generate negative pressure so that the vacuum suction cup 20 can adsorb the workpiece when working. The vacuum generating assembly 30 includes a vacuum tube inlet block 301, a vacuum generating tube 302, and a silencer tube 303 in sequence. The vacuum generating assembly 30 belongs to the prior art and is not a necessary technical feature of the technical solution involved in this utility model, so it will not be described in detail here.

[0030] In this utility model, the assembly of the housing 10 can be completed quickly by setting four side plates 103 and adapter blocks 104 in the side plate 103 unit. Compared with the traditional method of machining and cutting to manufacture vacuum suction cup housing, the processing difficulty is low and the production efficiency is high. At the same time, since the side plates 103 are detachably connected by adapters, the size of the side plates 103 can be adjusted according to the specific size of the vacuum generating component 30 during actual assembly, thereby improving the practicality of the spliced ​​vacuum suction cup 20 fixture and making it suitable for industrial applications.

[0031] In one specific embodiment, a locking block 110 is provided on the side of the adapter block 104 that is in contact with the side plate 103; the side plate 103 is provided with a slot 111 for the locking block 110 to engage. In this embodiment, the locking block 110 and the slot 111 enable the side plate 103 and the adapter block 104 to be detached and connected as needed.

[0032] In one specific embodiment, the adapter block 104 is provided with a third connecting hole 107 for connecting with the upper cover plate 101 and the lower cover plate 102; the upper cover plate 101 and the lower cover plate 102 are provided with a fourth connecting hole 108 corresponding to the third connecting hole 107. Specifically, during assembly, the adapter block 104 is connected to the third connecting hole 107 and the fourth connecting hole 108 by bolts, so as to effectively fix the adapter block 104, thereby improving the overall stability of the structure.

[0033] In one specific embodiment, the bottom of the lower cover plate 102 is provided with a fifth connecting hole 109 for mounting the vacuum suction cup 20. Specifically, the fifth connecting hole 109 is connected to the mounting cavity for mounting the vacuum generating assembly 30; during operation, the vacuum generating assembly 30 generates negative pressure, thereby causing the vacuum suction cup 20 to adsorb the workpiece.

[0034] In one specific embodiment, the vacuum suction cup 20 includes a pressure relief valve 201 connected to a fifth connection hole 109 and a suction cup body 202 connected to the pressure relief valve 201. Specifically, the pressure relief valve is used to close the fifth connection hole 109 when the suction cup body 202 connected to it cannot form an effective adsorption with the workpiece being adsorbed during operation, thereby effectively preventing vacuum leakage and improving the adsorption capacity of this type of modular vacuum suction cup 20 fixture.

[0035] In one specific embodiment, the check valve 201 includes a valve body 203, a valve core 204, and a sealing ball 205; the valve body 203 is installed below the fifth connecting hole 109, and the valve body 203 has a first air guide channel 206 communicating with the fifth connecting hole; the lower end of the first air guide channel 206 has an air outlet 208; the valve core 204 is installed at the upper end of the first air guide channel 206, and the valve core 204 has a second air guide channel 207 communicating with the first air guide channel 206; the sealing ball 205 is installed in the first air guide channel 206 and is located at the bottom of the valve core 204. Specifically, the radius of the second air guide channel 207 is smaller than the diameter of the sealing ball 205, so that the sealing ball 205 can effectively block the second air guide channel 207 when it moves toward the second air guide channel 207; the diameter of the air outlet 208 is smaller than the diameter of the sealing ball 205, so that the sealing ball 205 can be effectively located in the first air guide channel 206, and when the sealing ball 205 is above the air outlet 208, there is a gap between the sealing ball 205 and the sealing ball 205, so as to facilitate the effective adsorption of the workpiece by the suction cup body 202. Furthermore, during operation, when the vacuum generating component 30 generates negative pressure, the first air guiding channel 206 and the second air guiding channel 207, which are interconnected, cause the suction cup body 202 to adsorb the workpiece. When the suction cup body 202 effectively adsorbs the workpiece, the sealing ball 205 is located above the air outlet 208, but the air outlet 208 is not completely sealed. When the suction cup body 202 cannot effectively adsorb the workpiece, under the action of vacuum, the sealing ball 205 can overcome the action of gravity and be sucked to the bottom of the second air guiding channel 207. Its outer wall is attached to the bottom of the second air guiding channel 207 to block the second air guiding channel 207, thereby avoiding vacuum leakage and affecting the adsorption capacity of the vacuum suction cup 20 in other areas.

[0036] In one specific embodiment, the vent 208 consists of four splicing holes 209, each with a diameter smaller than that of the sealing ball 205, and the side of the splicing hole 209 that is attached to the sealing ball 205 is tilted downwards. In this embodiment, the arrangement of each splicing hole 209 effectively prevents the sealing ball 205 from blocking the vent 208, thereby interfering with vacuum release.

[0037] In one specific embodiment, the suction cup body 202 includes a connecting portion 210 connected to the check valve 201 and an adsorption portion 211 installed below the connecting portion 210. The adsorption portion 211 includes a first frustum portion 212 and a second frustum portion 213 arranged sequentially from top to bottom. The middle portions of the first frustum portion 212 and the second frustum portion 213 are both recessed inward to form a recessed portion 214, so that the cross-sectional shape of the adsorption portion 211 is a symmetrically arranged W shape. Specifically, by providing the first frustum portion 212, the second frustum portion 213, and the recessed portion 214, the axial deformation resistance of the adsorption portion 211 is improved, achieving a better adsorption effect.

[0038] In one specific embodiment, a thickened block 215 is provided at the bottom of the connecting part 210. In this embodiment, the thickened block 215 further improves the deformation resistance of the suction cup body 202, enhances the adsorption capacity, and extends the service life of the suction cup body 202.

[0039] This utility model relates to a modular vacuum suction cup 20 fixture. Through the arrangement of four side plates 103 and an adapter block 104 in the side plate 103 unit, the assembly of the mounting housing 10 can be completed quickly. Compared with the traditional machining method for manufacturing vacuum suction cup housings, the processing difficulty is low and the production efficiency is high. Furthermore, since the side plates 103 are detachably connected via adapters, the dimensions of the side plates 103 can be adjusted according to the specific size of the vacuum generating component 30 during actual assembly, thereby improving the practicality of the modular vacuum suction cup 20 fixture. The inclusion of a check valve 201 and the suction cup body 202 further enhances the deformation resistance and adsorption capacity of the modular vacuum suction cup 20 fixture, making it suitable for industrial applications.

[0040] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
