Description

Technical Field

[0001] The present invention relates to the field of pneumatic technology, in particular to a mounting device for a vacuum generator and a vacuum adsorption device. Background Art

[0002] Vacuum suction cups are currently widely used in automated equipment as important pneumatic components for picking up parts. In these devices, vacuum suction cups function as the fingers at the end of a robot arm, and can be used to pick up lightweight, sheet-like materials such as film, paper, glass, and electronic components.

[0003] For example, when it is used to adsorb electronic components to a circuit board, in order to improve production efficiency, a vacuum suction cup group is usually set up to adsorb multiple electronic components and load them at the same time.

[0026] Reference Figures 1 to 5 According to the first embodiment, the vacuum generator mounting device 100 includes: a mounting base 101 and a plurality of adjustment switches 102. The mounting base 101 is provided with: a first hole portion 103, a plurality of second hole portions 104, a plurality of third hole portions 105 and a plurality of fourth hole portions 106. In the mounting base 101, the first hole portion 103 is used to connect to an external high-pressure gas source 107. Each second hole portion 104 is used to accommodate a vacuum generator 201. Each third hole portion 105 connects each second hole portion 104 to the first hole portion 103. Each fourth hole portion 106 is used to connect to a vacuum suction cup 202 (auxiliary reference Figure 6 ). Each fourth hole portion 106 is connected to each second hole portion 104, and when a vacuum generator 201 is housed in the second hole portion 104, each fourth hole portion 106 faces the suction end 203 of each vacuum generator 201. Each adjustment switch 102 is provided with a first end portion 108 received in the third hole portion 105. The first end portion 108 can be fed along the axial direction of the third hole portion 105 to block or open the gap between the first hole portion 103 and the second hole portion 104.

[0027] The vacuum generator mounting device 100 of this embodiment can independently control the on / off state of each vacuum generator 201. Specifically, a mounting base 101 is used for mounting the vacuum generator 201. A first hole 103 for connecting to an external high-pressure gas source 107 is formed in the mounting base 101. Furthermore, an adjustment switch 102 for controlling the blockage or opening of the gap between the first hole 103 and the second hole 104 is installed in the mounting base 101. These adjustment switches 102 can independently block or open the gap between the first hole 103 and the second hole 104, thereby independently controlling the on / off state of each vacuum generator 201 housed in each second hole 104.

[0028] Continue to refer to Figure 5 The vacuum generator 201 of this embodiment can be, for example, a cylindrical vacuum generator 201. An air inlet 204 is provided at one axial end of the vacuum generator 201, and an air outlet 205 is provided at the other axial end. The suction end 203 is provided between the air outlet 205 and the air inlet 204. In addition, the air outlet 205 can be connected to a muffler (not shown). When the vacuum generator 201 is accommodated in the second hole portion 104, the air inlet 204 at one axial end of the vacuum generator 201 is located on a side of the second hole portion 104 adjacent to the first hole portion 103, and the air outlet 205 at the other axial end of the vacuum generator 201 is located at the end of the second hole portion 104 facing the outside (left side in the figure) of the mounting base 101. The suction end 203 is opposite to and connected to the fourth hole portion 106. In addition, the outer periphery of the vacuum generator 201 can be embedded with, for example, two O-rings 206, which are, for example, axially embedded on both sides of the adsorption end 203, thereby improving the sealing performance between the adsorption end 203 of the vacuum generator 201 and the mounting seat 101.

[0029] Continue to refer to Figure 3 、 Figure 4 , and auxiliary reference Figure 1 、 Figure 2 , the mounting base 101 is, for example, in the shape of a rectangular block. In order to reasonably arrange the structures of each hole portion, in some embodiments, the first hole portion 103 extends along a first direction (the front-to-back direction in the accompanying drawings), and the first direction is parallel to the length direction of the mounting base 101. In order to facilitate the processing of the first hole portion 103, the first hole portion 103 can directly pass through the mounting base 101 along the first direction. The specific opening position of the first hole portion 103 in the mounting base 101 is not particularly limited. For example, it can be opened at the lower right corner of the mounting base 101. A first plug (not shown, located on the front side of the mounting base 101) can be installed at one axial end of the first hole portion 103, and a first trachea connector 109 for installing a trachea can be installed at the other axial end of the first hole portion 103.

[0030] Continue to refer to Figure 3 , and auxiliary reference Figure 1In order to easily lay out the second hole portion 104, the second hole portion 104 extends along the second direction (left-right direction in the accompanying drawings), and the second direction is parallel to the width direction of the mounting base 101 and orthogonal to the first direction. The second hole portion 104 can, for example, extend from the left side of the mounting base 101, close to the upper part, toward the right side of the mounting base 101. In addition, the second hole portion 104 may not pass through the mounting base 101. The number of second hole portions 104 is not particularly limited and can be determined according to the number of vacuum generators 201 to be installed. For example, the number of second hole portions 104 can include 6 to 8. The second hole portions 104 can be evenly spaced along the first direction of the mounting base 101. The end of the second hole portion 104 located on the left side of the mounting base 101 can be used for exhausting the air outlet end 205 of the vacuum generator 201. In addition, when the air outlet portion 110 (described later) for exhausting the vacuum generator 201 is opened at other positions on the mounting seat 101, the second hole portion 104 can also be blocked. For example, the end of the second hole portion 104 located on the left side of the mounting seat 101 can be blocked by the second plug 111.

[0031] Continue to refer to Figure 5 , the third hole portion 105 is appropriately opened according to the positions of the first hole portion 103 and each second hole portion 104. The third hole portion 105 can, for example, extend along a third direction (the up-down direction in the accompanying drawings), which is parallel to the height direction of the mounting base 101 and orthogonal to the first direction and the second direction respectively. In order to easily connect the second hole portion 104 and the first hole portion 103, the third hole portion 105 is opened from a position close to the right side of the upper surface of the mounting base 101. The diameter and depth of the third hole portion 105 are not particularly limited. For example, one axial end of the third hole portion 105 passes through the wall of the first hole portion 103 to communicate with the first hole portion 103. In addition, one axial end of the second hole portion 104 passes through the wall of the third hole portion 105 to communicate with the third hole portion 105. That is, the depth of the downward extension of the third hole portion 105 is sufficient as long as it can pass through the wall of the first hole portion 103. Furthermore, the rightward extension depth of the second hole portion 104 only needs to be sufficient to penetrate the wall of the third hole portion 105. Thus, the axial lower end of the third hole portion 105 communicates with the first hole portion 103, while the axial right end of the second hole portion 104 communicates with the third hole portion 105 at the wall of the third hole portion 105. By ensuring that the lower end of the third hole portion 105 communicates with the first hole portion 103 and the wall of the third hole portion 105 communicates with the right end of the second hole portion 104, the lower end of the third hole portion 105 and / or the right end of the second hole portion 104 can be easily closed or opened by adjusting the switch 102, thereby easily achieving the sealing or opening between the first hole portion 103 and the third hole portion 105.

[0032] Continue to refer to Figure 5 , and auxiliary reference Figure 1、 Figure 2 The fourth hole 106 can also extend in the third direction, for example. Specifically, the fourth hole 106 can be appropriately positioned based on the position of the suction hole of the suction end 203 of the vacuum generator 201. To facilitate installation of the vacuum suction cup 202 or the second air pipe connector 112 connected to the vacuum suction cup 202, the fourth hole 106 can be, for example, opened downward from approximately the middle of the upper surface of the mounting base 101 in the left-right direction. The fourth hole 106 can be, for example, a threaded hole.

[0033] Continue to refer to Figure 5 , and auxiliary reference Figures 1 to 4 Furthermore, in some embodiments, to facilitate exhaust of the vacuum generator 201, the mounting base 101 may be provided with multiple air outlets 110. Each air outlet 110 is connected to a respective second hole 104. When a vacuum generator 201 is placed in a second hole 104, each air outlet 110 is connected to the air outlet end 205 of each vacuum generator 201. Specifically, in some embodiments, the air outlet 110 includes multiple air outlet holes 113, each air outlet hole 113 being connected to the corresponding second hole 104. The air outlet holes 113 may be provided on the top surface of the mounting base 101, facing the air outlet end 205 of the vacuum generator 201, thereby facilitating exhaust of the vacuum generator 201. Furthermore, the provision of the air outlet 110 allows the left end of the second hole 104 to be sealed with a second plug 111, preventing the vacuum generator 201 from being exposed.

[0034] Continue to refer to Figure 5 As described above, each adjustment switch 102 is provided with a first end portion 108 received within the third hole portion 105. The first end portion 108 can be advanced along the axial direction of the third hole portion 105 to close or open the gap between the first hole portion 103 and the second hole portion 104. Specifically, the adjustment switch 102 further includes a knob portion 114 exposed outside the mounting base 101. The knob portion 114 and the first end portion 108 are integrally formed. By grasping the knob portion 114 and rotating or pushing the adjustment switch 102, the first end portion 108 can be advanced within the third hole portion 105.

[0035] In some embodiments, to easily and reliably disconnect the first hole 103 from the second hole 104 corresponding to the adjustment switch 102, a tapered portion 115 is provided at the distal end (the lower end in the figures) of the first end portion 108. The tapered portion 115 can abut against the wall of the first hole 103 at the location where it communicates with the third hole 105. The provision of the tapered portion 115 allows the adjustment switch 102 to adaptively adjust according to the lower end of the third hole 105, thereby reliably blocking the location where the lower end of the third hole 105 communicates with the wall of the first hole 103.

[0036] Furthermore, in some embodiments, at least a portion of the wall of the third hole 105 is provided with a first internal thread 116, and the first end portion 108 is provided with a first external thread 117 that screws into the first internal thread 116. Specifically, the provision of the first internal thread 116 and the first external thread 117 allows the first end portion 108 to be easily advanced within the third hole 105 by rotating the knob 114 of the adjustment switch 102. To open or close the vacuum generator 201, simply rotating the knob 114 of the adjustment switch 102 is sufficient. For example, the first internal thread 116 can be provided at the lower end of the third hole 105, and the first external thread 117 can be provided at the lower end of the first end portion 108. Thus, the first internal thread 116 not only serves as a thread for advancing the first end portion 108 of the adjustment switch 102, but also seals the connection between the lower end of the third hole 105 and the wall of the first hole 103. That is, the threaded engagement of the tapered portion 115 with the first internal thread 116 and the first external thread 117 can provide double sealing, thereby greatly improving the reliability of the position of the first end portion 108 of the regulating switch 102 that blocks the lower end portion of the third hole 105 .

[0037] In some embodiments, to limit the travel of the adjustment switch 102 and prevent it from falling off, the mounting base 101 further includes a plurality of fifth holes 118, each of which is connected to each of the third holes 105. Each fifth hole 118 houses a limiting member 119, with the end (left end) of the limiting member 119 extending into the third hole 105 and limiting the travel of the adjustment switch 102 within the third hole 105 in the direction that opens the first hole 103 and the second hole 104. Specifically, the fifth hole 118 is, for example, provided on the right side of the mounting base 101. The position of the fifth hole 118 is appropriately determined based on the position of the third hole 105. The fifth hole 118 can be, for example, a threaded hole, and the limiting member 119 can be, for example, a screw. In this embodiment, the direction in which the adjustment switch 102 moves in the direction that opens the first hole 103 and the second hole 104 is upward. That is, in this embodiment, when the first end portion 108 of the regulating switch 102 is fed downward, the lower end portion of the third hole portion 105 is blocked, thereby blocking the first hole portion 103 and the second hole portion 104. When the first end portion 108 of the regulating switch 102 is fed upward, the lower end portion of the third hole portion 105 is opened, thereby connecting the first hole portion 103 and the second hole portion 104.

[0038] Furthermore, in some embodiments, to limit the travel of the regulating switch 102, the first end 108 of the regulating switch 102 may be provided with, for example, an annular first groove 120, with the end of the limiting member 119 extending into the first groove 120. Specifically, the diameter of the first groove 120 may be, for example, smaller than the mid-diameter of the first external thread 117. After the first end 108 is inserted into the third hole 105 and the lower end of the first end 108, provided with the first external thread 117, crosses the fifth hole 118, the position of the first groove 120 and the position of the fifth hole 118 are opposite. Thus, when the regulating switch 102 is advanced upward, the lower end of the first end 108 is restrained by the left end of the limiting member 119, thereby limiting the travel of the regulating switch 102 in the upward direction.

[0039] Reference Figure 6 , and auxiliary reference Figures 1 to 5 The vacuum generator mounting device 100 of each of the above embodiments can be used in the vacuum adsorption device 200. Specifically, the vacuum adsorption device 200 of the second embodiment includes: the above-mentioned vacuum generator mounting device 100, a plurality of vacuum generators 201 and a plurality of vacuum suction cups 202. Each vacuum generator 201 is cylindrical and is accommodated in the second hole portion 104 of the mounting seat 101. The air inlet end 204 of the vacuum generator 201 is connected to the first hole portion 103 through the third hole portion 105. The adsorption end 203 of the vacuum generator 201 is connected to the fourth hole portion 106. Each vacuum suction cup 202 is respectively connected to the fourth hole portion 106 of the mounting seat 101. Each vacuum suction cup 202 can be directly mounted on the first hole portion 103 or connected to the fourth hole portion 106 through an air pipe.

[0040] According to the vacuum adsorption device 200 of this embodiment, the on / off of each vacuum generator 201 can be independently controlled, so that each vacuum suction cup 202 can be easily operated independently without affecting each other.

[0041] The various specific technical features described in the above specific embodiments can be combined in any way without contradiction. To avoid unnecessary repetition, this embodiment does not separately describe various possible combinations.

[0042] The above embodiments are only used to illustrate the technical solutions of this embodiment and are not intended to limit the same. Any modifications or equivalent replacements that do not depart from the scope of this embodiment shall be included in the technical solutions of this embodiment.
