Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a suction cup dust cover. Background Art

[0002] In daily life, suction cup assemblies are often used to adsorb and fix on smooth surfaces. During the production process of the suction cup assemblies, in order to prevent dust or other foreign matter from adhering to the adsorption surface of the suction cup made of soft rubber material and causing the adsorption force of the adsorption surface to decrease, a removable dust cover is usually provided on the outer periphery of the adsorption surface of the suction cup.

[0003] The dust cover has an installation groove for accommodating the suction cup, and the inner peripheral wall of the installation groove is tightly matched with the outer peripheral wall of the suction cup to prevent the suction cup assembly and the dust cover from being easily separated. During the automated assembly process, the robot grasps the suction cup and quickly moves toward the bottom of the installation groove to insert the suction cup into the installation groove. During this process, the gas in the installation groove has no time to be discharged, causing the dust cover to bulge. The overall volume of the dust cover and the suction cup is large, which is not conducive to storage and transfer to the next process. Alternatively, the instantaneously compressed gas is ejected from between the outer peripheral wall of the suction cup and the inner peripheral wall of the installation groove, causing the suction cup to be subjected to a large impact and produce irreversible deformation. At this time, the adsorption surface will also be vacuum adsorbed on the bottom wall of the installation groove, making it difficult for the user to remove the dust cover and causing the adsorption force of the adsorption surface to decrease. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a suction cup dust cover which will not cause the dust cover to bulge, avoid deformation and damage of the suction cup, and facilitate separation of the dust cover and the suction cup.

[0005] According to an embodiment of the utility model, a suction cup dust cover includes: a cover body, the cover body having a mounting groove opening upward; the cover body is provided with an exhaust hole groove penetrating through the bottom wall of the mounting groove, and / or the inner circumferential wall of the cover body is provided with an exhaust groove concavely arranged along a direction away from the middle of the mounting groove, and the exhaust groove is communicated with the mounting groove.

[0006] The suction cup dust cover according to the embodiment of the utility model has at least the following beneficial effects:

[0007] When the cover body and the suction cup are transferred together, the suction cup is inserted toward the bottom of the installation trough. During this process, the gas in the installation trough can be efficiently discharged from the exhaust hole groove or the exhaust groove, avoiding the cover body from arching and deformation, which is conducive to storage and transfer to the next process. It will not cause the suction cup to be subjected to a large impact and produce irreversible deformation, and the suction cup will not be vacuum adsorbed on the bottom wall of the installation trough, making it difficult for users to disassemble it. It is conducive to the smooth separation of the cover body to ensure the adsorption force of the suction cup.

[0008] In some embodiments of the utility model, the bottom wall of the installation sink is a circular plate, the exhaust hole is a cross hole, the center of the cross hole is concentric with the circular plate, and the width of the cross hole is a, which satisfies: 0.2mm≤a≤2.5mm. When the gas in the installation sink is compressed, part of it can overflow from the cross hole, and when the width of the cross hole meets the above range, it is not easy for external dust to enter the installation sink along the cross hole to contaminate the adsorption surface of the suction cup.

[0009] In some embodiments of the present invention, the length of the cross through hole is less than or equal to the radius of the circular plate, thereby preventing dust from contacting the outer peripheral edge of the adsorption surface of the suction cup to a certain extent.

[0010] In some embodiments of the utility model, the middle part of the circular plate has a circular hole area concentrically arranged therewith, the diameter of the hole area is less than or equal to the radius of the circular plate, and a plurality of scattered perforations are arranged in the hole area, the diameter of the perforations is b, and satisfies: 0.5mm≤b≤2mm. When a plurality of scattered perforations are arranged in the circular hole area, and the diameter of the perforations satisfies the above range, the gas can be discharged and the hood body can be prevented from being deformed by arching, and external dust is not easy to enter the installation sink along the perforations and contaminate the adsorption surface of the suction cup.

[0011] In some embodiments of the utility model, the inner peripheral wall of the installation sink includes a circle of annular walls connected to the bottom wall of the installation sink and a truncated cone wall connected to the upper end of the annular wall, and the truncated cone wall is inclined from bottom to top away from the annular wall. The setting of the truncated cone wall is conducive to guiding the suction cup member to be inserted along the depth direction of the installation sink, avoiding the problem of inaccurate relative position between the suction cup member and the cover body and thus being unable to be assembled.

[0012] In some embodiments of the utility model, the angle of inclination of the truncated cone wall relative to the annular wall is c, which satisfies: 2°≤c≤30°. When the angle of inclination of the truncated cone wall relative to the annular wall satisfies the above range, the suction cup can be easily and smoothly inserted into the installation sink without leaving too large a gap to generate dust accumulation.

[0013] In some embodiments of the utility model, the exhaust groove is formed on the annular wall and the truncated cone wall, and the exhaust groove is extended in the vertical direction. The upper end of the vertical exhaust groove has a larger exhaust space, which is conducive to increasing the flow rate of gas exhaust.

[0014] In some embodiments of the utility model, the groove depth of the exhaust groove formed on the part of the annular wall is d, and the groove width of the exhaust groove formed on the part of the annular wall is e, which satisfies: 0.6mm≤d≤1.2mm, 3.6mm≤e≤7.2mm. When the exhaust groove meets the above set conditions, the structure of the cover body takes into account the assembly requirements of the suction cup and the requirements for gas discharge in the installation sink, and external dust is not easy to enter the installation sink along the exhaust groove and contaminate the adsorption surface of the suction cup.

[0015] In some embodiments of the utility model, the cross-section of the exhaust groove is roughly triangular, and arc guide surfaces are provided between the two sides of the exhaust groove and the annular wall. The provision of the arc guide surface can reduce exhaust noise and is also conducive to smooth gas discharge.

[0016] In some embodiments of the utility model, the upper end of the inner peripheral wall of the installation sink is provided with a plurality of limiting protrusions for limiting the upward separation of the suction cup from the cover body at intervals around the circumference thereof, and when the suction cup contacts the lower end of the limiting protrusion, a height gap is provided between the bottom wall of the installation sink and the suction cup, and an exhaust channel is defined between the exhaust groove and the suction cup. That is, the exhaust channel is formed between the outer peripheral wall of the suction cup and the exhaust groove, the upper end of the exhaust channel is connected to the outside, and the lower end of the exhaust channel is connected to the height gap.

[0017] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] As mentioned above, in the production process of automated assembly, the robot grasps the suction cup 200 and quickly inserts it into the installation groove 110 of the cover body 100. During this process, the gas in the installation groove 110 has no time to be discharged, resulting in the cover body 100 being arched. The overall volume formed by the cover body 100 and the suction cup 200 is relatively large, which is not conducive to storage and transfer to the next process, or the instantaneously compressed gas is ejected from the outer peripheral wall of the suction cup 200 and the inner peripheral wall of the installation groove 110, and the suction cup 200 is subjected to a large impact and produces irreversible deformation. At this time, the adsorption surface will also be vacuum adsorbed on the bottom wall of the installation groove 110, making it difficult for the user to remove the cover body 100, resulting in the problem of reduced adsorption force of the adsorption surface of the suction cup 200.

[0029] Reference Figures 1 to 3 The utility model provides a suction cup dust cover, comprising: a cover body 100, wherein the cover body 100 has a mounting groove 110 opening upward; the cover body 100 is provided with an exhaust hole groove 120 penetrating through the bottom wall of the mounting groove 110, and / or the inner peripheral wall of the cover body 100 is provided with an exhaust groove 130 concavely arranged in a direction away from the middle of the mounting groove 110, and the exhaust groove 130 is communicated with the mounting groove 110.

[0030] When the cover body 100 and the suction cup member 200 are transferred together, the suction cup member 200 is inserted toward the bottom of the installation groove 110, and the outer peripheral wall of the suction cup member 200 is tightly matched with the installation groove 110. During this process, the gas in the installation groove 110 can be efficiently discharged from the exhaust hole groove 120 or the exhaust groove 130, avoiding the cover body 100 from arching and deformation, which is beneficial for storage and transfer to the next process, and will not cause the suction cup member 200 to be subjected to a large impact and produce irreversible deformation, and the suction cup member 200 will not be vacuum adsorbed on the bottom wall of the installation groove 110, making it difficult for the user to disassemble it. It is beneficial to the smooth separation of the cover body 100 to ensure the adsorption force of the suction cup member 200.

[0031] See also Figure 1 In some embodiments of the utility model, the bottom wall of the installation sink 110 is a circular plate, the exhaust hole groove 120 is a cross-through hole groove, the center of the cross-through hole groove is concentric with the circular plate, and the groove width of the cross-through hole groove is a (not shown in the figure), which satisfies: 0.2mm≤a≤2.5mm. It can be understood that when the gas in the installation sink 110 is compressed, part of it can overflow from the cross-through hole groove. When the groove width of the cross-through hole groove meets the above range, external dust is not easy to enter the installation sink 110 along the cross-through hole groove to contaminate the adsorption surface of the suction cup 200. When the cover body 100 can undergo elastic deformation on the bottom wall of the installation sink 110, the cross-through hole groove with a smaller groove width can also be deformed to expand the groove width so that the high-pressure gas can be discharged outward, and then the elastic deformation is restored to make the groove width smaller again.

[0032] See also Figure 1 In some embodiments of the utility model, the length dimension of the cross through hole groove is less than or equal to the radius dimension of the circular plate. It should be noted that, generally speaking, the adsorption surface of the suction cup member 200 is roughly spherical, and the distance between the middle of the adsorption surface and the circular plate is the farthest, that is, the gas is largely concentrated between the middle of the adsorption surface and the circular plate. The length dimension of the cross through hole groove is less than or equal to the radius dimension of the circular plate, which is helpful for the gas discharge in the installation sink 110, and can also prevent dust from contacting the outer peripheral edge of the adsorption surface of the suction cup member 200 to a certain extent.

[0033] In some embodiments of the utility model, the middle part of the circular plate has a circular hole area (not shown in the figure) arranged concentrically therewith, the diameter of the hole area is less than or equal to the radius of the circular plate, and a plurality of scattered perforations are arranged throughout the hole area, the diameter of the perforations is b (not shown in the figure), and satisfies: 0.5mm≤b≤2mm. It should be noted that, generally speaking, the adsorption surface of the suction cup 200 is roughly spherical, and the distance between the middle part of the adsorption surface and the circular plate is the farthest, that is, the gas is largely concentrated between the middle part of the adsorption surface and the circular plate. When a plurality of scattered perforations are arranged in the circular hole area, and the diameter of the perforations meets the above range, the gas can be discharged and the cover body 100 can be prevented from arching and deforming, and external dust is not easy to enter the installation sink 110 along the perforations and contaminate the adsorption surface of the suction cup 200.

[0034] See also Figure 1 , Figure 2 and Figure 3 In some embodiments of the present invention, the inner peripheral wall of the installation sink 110 includes a circle of annular walls 140 connected to the bottom wall of the installation sink 110 and a truncated cone wall 150 connected to the upper end of the annular wall 140, and the truncated cone wall 150 is arranged to be inclined from the annular wall 140 upward away from the annular wall 140. It can be understood that the annular wall 140 is tightly matched with a part of the outer peripheral wall of the suction cup member 200, thereby preventing the cover body 100 from falling off the suction cup member 200. The setting of the truncated cone wall 150 is conducive to guiding the suction cup member 200 to be inserted along the depth direction of the installation sink 110, avoiding the problem that the relative position between the suction cup member 200 and the cover body 100 is inaccurate and cannot be assembled.

[0035] See also Figure 2 In some embodiments of the present invention, the angle of inclination of the truncated cone wall 150 relative to the annular wall 140 is c, which satisfies: 2°≤c≤30°. After testing, when the angle of inclination of the truncated cone wall 150 relative to the annular wall 140 satisfies the above range, the suction cup member 200 can be easily and smoothly inserted into the installation sink 110, and there will be no excessive gap to generate dust accumulation.

[0036] See also Figure 1 and Figure 2 In some embodiments of the present invention, the exhaust groove 130 is formed on the annular wall 140 and the truncated cone wall 150, and the exhaust groove 130 is extended in the vertical direction. It can be understood that since the truncated cone wall 150 is inclined from bottom to top away from the annular wall 140, the upper end of the vertically arranged exhaust groove 130 has a larger exhaust space, which is conducive to increasing the flow rate of gas exhaust.

[0037] See also Figure 2In some embodiments of the utility model, the groove depth of the exhaust groove 130 formed on the annular wall 140 is d, and the groove width of the exhaust groove 130 formed on the annular wall 140 is e, which satisfies: 0.6mm≤d≤1.2mm, 3.6mm≤e≤7.2mm. When the exhaust groove 130 meets the above set conditions, the structure of the cover body 100 takes into account the assembly requirements of the suction cup 200 and the requirements for gas discharge in the installation sink 110. When the groove depth d of the exhaust groove 130 formed on the annular wall 140 satisfies: 0.6mm≤d≤1.2mm, external dust is not easy to enter the installation sink 110 along the exhaust groove 130 and contaminate the adsorption surface of the suction cup 200.

[0038] See also Figure 2 In some embodiments of the present invention, the cross-sectional shape of the exhaust groove 130 is roughly triangular, and arc guide surfaces are provided between the two sides of the exhaust groove 130 and the annular wall 140. It should be noted that the gas can enter the exhaust groove 130 along the surface of these arc guide surfaces, and then be discharged upward from the exhaust groove 130. The provision of the arc guide surfaces can reduce exhaust noise and is also conducive to smooth gas discharge.

[0039] See also Figure 1 and Figure 3 In some embodiments of the utility model, a plurality of limiting protrusions 160 for limiting the suction cup member 200 from upwardly separating from the cover body 100 are distributed around the upper end of the inner circumferential wall of the mounting groove 110 at intervals in the circumferential direction. When the suction cup member 200 contacts the lower end of the limiting protrusion 160, a height gap is provided between the bottom wall of the mounting groove 110 and the suction cup member 200. An exhaust channel 300 is defined between the exhaust groove 130 and the suction cup member 200, that is, the exhaust channel 300 is formed between the outer circumferential wall of the suction cup member 200 and the exhaust groove 130. The upper end of the exhaust channel 300 is connected to the outside, and the lower end of the exhaust channel 300 is connected to the height gap. Specifically, multiple limiting protrusions 160 and exhaust grooves 130 are provided. The multiple limiting protrusions 160 are not only used to prevent the suction cup 200 from falling off, but also can improve the mechanical strength of the cover body 100. The multiple exhaust grooves 130 are not only used for exhaust, but also can improve the mechanical strength of the cover body 100 to avoid excessive deformation of the cover body 100.

[0040] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
