Description

[0002] In the field of electric vehicles, it is often necessary to move or transport sheet metal or glass. In order to achieve automated production and avoid leaving marks on the workpiece, especially the glass, it is often necessary to use robots and pneumatic suction cups to move the glass.

[0003] During use, the existing pneumatic suction cup equipment is generally equipped with multiple devices, which are controlled by built-in modular chips. Although the existing suction cups can automatically pump and deflate air and automatically adsorb workpieces or glass, when not in use, since the pneumatic suction cups are generally directly exposed, dust will inevitably accumulate on the pneumatic suction cups. The accumulation of dust will cause the adsorption force of the pneumatic suction cups to decrease, thereby reducing the service life of the pneumatic suction cups (after the adsorption force decreases, the suction cups need to be replaced to ensure stability during adsorption). Although dust covers can be manually put on, there are generally more suction cups on a bracket, and putting on dust covers one by one makes the workers' workload large, and it is inconvenient to put on dust covers one by one, which is not conducive to fully automated production.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Example 1, reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, and this embodiment provides a modular pneumatic suction cup device, which can automatically prevent the pneumatic suction cup from dust when the pneumatic suction cup is not in use, and includes an adsorption component 100, including multiple suction cup bodies 101, multiple support tubes 102 arranged on the multiple suction cup bodies 101, a bracket 103 arranged on the support tube 102, a negative pressure pump 104 arranged on the bracket 103, and a pipe 105 arranged on the negative pressure pump 104; a dustproof component 200, including a lifting component 201 arranged on the support tube 102, a bearing component 202 arranged on the lifting component 201, a flipping component 203 arranged on the bearing component 202, a toggle component 204 arranged on the flipping component 203, and a closing component 205 arranged on the flipping component 203; a shielding component 300, including a pushing component 301 arranged on the support tube 102, an extension component 302 arranged on the bearing component 202, and an elastic component 303 arranged on the extension component 302.

[0028] Specifically, a threaded structure is provided on the bracket 103 here, which can adjust the position and height of the pneumatic suction cup. The air suction of the pneumatic suction cup is automatically controlled by the module unit to ensure that the sheet metal or glass can be adsorbed. A robotic arm is connected to the bracket 103 to move the bracket 103. The above is the existing technology and will not be elaborated here.

[0029] Furthermore, the lifting assembly 201 includes three guide plates 201a fixedly connected to the support tube 102, and the three guide plates 201a are all provided with electric slide rails 201b, and the three guide plates 201a are slidably connected with circular rings 201c, and the circular rings 201c are provided with lifting blocks 201d that cooperate with the electric slide rails 201b; the bearing assembly 202 includes a mounting ring 202a fixedly connected to the circular ring 201c, and three pairs of fixed blocks 202b are fixedly connected to the mounting ring 202a, and the three pairs of fixed blocks 202b are penetrated and rotatably connected with a rotating shaft 202c; the flipping assembly 203 includes an L-shaped plate 203a fixedly connected to the rotating shaft 202c, and a dustproof shell 203b is fixedly connected to the L-shaped plate 203a; the cross-sections of the three dustproof shells 203b are L-shaped, and the edges of the three dustproof shells 203b are all arc-shaped, and the arc edges of the outer edges of the three dustproof shells 203b are 120°.

[0030] Among them, a gap is left between the dustproof shell 203b and the mounting ring 202a to prevent the dustproof shell 203b from getting stuck with the mounting ring 202a when rotating. The bottoms of the three dustproof shells 203b are spliced ​​into a disc 204b with a diameter larger than the pneumatic suction cup, thereby fully protecting the lower side of the suction cup body 101 to prevent dust from entering.

[0031] Preferably, the toggle assembly 204 includes a U-shaped rod 204a that passes through and is slidably connected to the fixed block 202b, a disk 204b is fixedly connected to the U-shaped rod 204a, and the disk 204b is elastically connected to the inside of the fixed block 202b through a first spring 204c, a toggle rod 204d is fixedly connected to the U-shaped rod 204a, an arc groove 204e that cooperates with the toggle rod 204d is provided on the rotating shaft 202c, and two inclined surfaces 204f that cooperate with the U-shaped rod 204a are provided on the guide plate 201a. A ball can be set on the toggle rod 204d, and the cooperation between the ball and the arc groove 204e can better drive the rotating shaft 202c to rotate.

[0032] When in use, in the initial state, the dust cover 203b is on the upper side of the suction cup body 101 and will not affect the use of the suction cup body 101. When the suction cup body 101 is not in use, it is only necessary to start the electric slide rail 201b to make the lifting block 201d descend. During the downward movement of the lifting block 201d, the U-shaped rod 204a first cooperates with the inclined surface 204f at the upper end of the guide plate 201a, so that the U-shaped rod 204a moves outward, and the first spring 204c is compressed, so that the lever 204d moves away from the suction cup body 101. The fixed block 202b moves in the direction of rotation, and the lever 204d cooperates with the arc groove 204e to drive the rotating shaft 202c to rotate, so that the L-shaped plate 203a deflects, so that the three dustproof shells 203b are opened, so that the dustproof shells 203b will not abut against the upper end of the suction cup body 101 during the downward movement. As the ring 201c moves downward, the mounting ring 202a moves downward, so that the dustproof shells 203b move to the lower side of the suction cup body 101 through the L-shaped plate 203a; When the dust cover 203b moves to the lower side of the suction cup body 101, the U-shaped rod 204a cooperates with the inclined surface 204f at the lower end of the guide plate 201a. At this time, under the action of the first spring 204c, the U-shaped rod 204a is reset, driving the lever 204d to reset. At this time, the lever 204d cooperates with the arc groove 204e on the shaft 202c, driving the shaft 202c to reset, and the L-shaped plate 203a is reset, driving the three dust covers 203b to block the lower side of the suction cup body 101. Since the bottoms of the three dust covers 203b are spliced ​​into a diameter The disc 204b is larger than the pneumatic suction cup, so that the lower side of the suction cup body 101 can be protected to prevent dust from accumulating on the suction cup body 101 and affecting the adsorption effect. It should be noted that when the dustproof shell 203b is closed, there is a gap between the inner bottom of the dustproof shell 203b and the lower end surface of the suction cup body 101 to prevent the dustproof shell 203b from getting stuck with the suction cup body 101 when it is unfolded. When the dustproof shell 203b needs to be unfolded, it is only necessary to move the U-shaped rod 204a upward and return along the original path.

[0033] In summary, by providing the adsorption component 100 and the dustproof component 200, when the suction cup body 101 is not in use, the three dustproof shells 203b can be closed on the outside of the suction cup body 101, and the bottom of the dustproof shells 203b are spliced ​​into a disc 204b with a diameter larger than the pneumatic suction cup, so as to protect the suction cup body 101 and prevent dust from accumulating on the suction cup body 101 and affecting the adsorption effect. At the same time, the dustproof shell 203b wraps the suction cup body 101, which can also reduce the accumulation of dust on the outer shell of the suction cup body 101.

[0034] Example 2, reference Figure 1 to Figure 6, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a closing component 205 of a modular pneumatic suction cup device, which solves the problem of how to automatically close the dustproof shell 203b when the dustproof shell 203b is not in use to prevent dust from entering the dustproof shell 203b. It includes a closing component 205, including an arc-shaped opening 205a arranged on the dustproof shell 203b, a receiving groove 205b is arranged in the arc-shaped opening 205a, a fan-shaped plate 205c is slidably connected to the receiving groove 205b, and the fan-shaped plate 205c is elastically connected to the inner wall of the receiving groove 205b through a second spring 205d.

[0035] Specifically, the three arc-shaped openings 205 a are spliced ​​into a circular opening with a diameter greater than that of the support tube 102 , and a sealing strip may be provided on the inner wall of the arc-shaped opening 205 a , so as to seal the dustproof shell 203 b and the support tube 102 .

[0036] During use, when the dustproof shell 203b is on the upper side of the suction cup body 101, the arc-shaped opening 205a on the dustproof shell 203b cooperates with the support tube 102, so that the dustproof shell 203b is still in a closed state, and dust will not enter the dustproof shell 203b, causing the dust in the dustproof shell 203b to enter the suction cup body 101 when the suction cup body 101 is blocked. When the dustproof shell 203b moves to the lower side of the suction cup body 101, since the fan-shaped plate 205c lacks something to offset it, under the action of the second spring 205d, the fan-shaped plate 205c automatically resets to block the bottom of the suction cup body 101, and does not affect the dustproofing of the suction cup body 101.

[0037] In summary, by setting the closing component 205, when the dustproof shell 203b is in a closed state and the suction cup body 101 is in a closed state, the arc-shaped opening 205a cooperates with the support tube 102 to make the dustproof shell 203b in a completely closed state, and dust will not enter the dustproof shell 203b, thereby ensuring the cleanliness of the dustproof shell 203b and avoiding the phenomenon that dust sticks to the suction cup body 101 when the dustproof shell 203b blocks the suction cup body 101.

[0038] Example 3, reference Figures 1 to 8, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a shielding component 300 of a modular pneumatic suction cup device, which solves the problem of how to shield the gap between the mounting ring 202a and the dustproof shell 203b to achieve a better dustproof effect. It includes a pushing component 301, including a positioning ring 301a fixedly connected to the upper end of the support tube 102, an annular groove 301b is provided on the mounting ring 202a, and a plurality of through-holes 301c are provided on the upper and lower inner walls of the annular groove 301b. The plurality of through-holes 301c are all slidably connected with an I-shaped block 301d, and the I-shaped block 301d is connected to the third spring 301d by the third spring 301d. 01e is elastically connected to the inner wall of the through-opening 301c; the extension component 302 includes a plurality of sliding sleeves 302a fixedly connected in the annular groove 301b, and the plurality of sliding sleeves 302a are fixedly connected with strip plates 302b, and the upper and lower ends of the plurality of strip plates 302b are provided with cutting edges 302c, and the outer ends of the strip plates 302b are fixedly connected with arc plates 302d; the elastic component 303 includes an inner groove 303a fixedly connected to the arc plate 302d, and an extension block 303b is slidably connected in the inner groove 303a, and the extension block 303b is elastically connected to the inner wall of the inner groove 303a through a fourth spring 303c.

[0039] Specifically, the setting of the I-shaped block 301d prevents the I-shaped block 301d from being separated from the through-hole 301c, and the setting of the cutting edge 302c prevents the strip plate 302b from being stuck with the I-shaped block 301d. The end of the inner groove 303a close to the annular groove 301b is completely open, and the gap between the dust cover 203b and the mounting ring 202a is smaller than the width of the extension block 303b, so that the extension block 303b can completely block the gap.

[0040] When in use, when the dust cover 203b is in a closed state, that is, the U-shaped rod 204a is on the upper side of the upper end inclined surface 204f and the lower side of the lower end inclined surface 204f, the U-shaped rod 204a does not cooperate with the inclined surface 204f, and the I-shaped block 301d and the strip plate 302b are against each other, so that the strip plate 302b moves outward, driving the arc plate 302d to move outward to fill the gap between the mounting ring 202a and the dust cover 203b. As the arc plate 302d moves outward, the circle formed becomes larger. At this time, under the action of the fourth spring 303c, the extension block protrudes to the outside of the inner groove 303a to perform the arc plate 302d movement. 2d moves outward to form a gap filling, ensuring that the gap between the mounting ring 202a and the dustproof shell 203b can be filled, and when the arc plate 302d and the extension block move outward, there is no gap between the mounting ring 202a and the dustproof shell 203b, so that the dustproof shell 203b cannot be unfolded, thereby achieving a better sealing effect. When the dustproof shell 203b needs to be unfolded, the mounting ring 202a moves first. Since there is a distance between the U-shaped rod 204a and the inclined surface 204f, this distance is enough for the arc plate 302d to reset, so that when the U-shaped rod 204a and the inclined surface 204f are against each other, the dustproof shell 203b will not be blocked.

[0041] In summary, by setting the shielding component 300, when the mounting ring 202a reaches the specified position, that is, after the dustproof shell 203b is closed, the extension block and the arc plate 302d can be automatically extended to fill the gap between the mounting ring 202a and the dustproof shell 203b, so as to achieve a better dustproof effect.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
