[0032] Example 1

[0033] This embodiment provides a product transferring device, which includes a transferring module and a suction cup. The suction cup is used to absorb the product, and the transferring module is used to drive the suction cup to move, thereby driving the product to move. It can be understood that the transferring module can be selected as a robot or a three-axis moving module, etc., and this embodiment does not impose specific restrictions on this.

[0034] See also Figure 1 and Figure 2In this embodiment, the suction cup includes a joint 1 and a mounting frame, wherein the joint 1 is configured to be engaged with a transfer module for driving the suction cup to move, the joint 1 is fixedly connected to the middle position of the mounting frame, and the mounting frame includes a first mounting plate 24, the first mounting plate 24 includes a first plate portion 241 and a second plate portion 242, the first plate portion 241 and the second plate portion 242 are respectively located on both sides of the joint 1, and a first suction nozzle 21 is provided on the first plate portion 241 and the second plate portion 242, and a second mounting plate 25 is detachably mounted on the side of the first plate portion 241 away from the joint 1, and a third mounting plate 26 is detachably mounted on the side of the second plate portion 242 away from the joint 1, and a second suction nozzle 221 and a third suction nozzle 222 are respectively provided on the second mounting plate 25 and the third mounting plate 26, and the angle between the second mounting plate 25 and the first plate portion 241 is adjustable, and the angle between the third mounting plate 26 and the second plate portion 242 is adjustable.

[0035] Based on the above, in this embodiment, when the second mounting plate 25 and the third mounting plate 26 are removed, the adsorption area of the suction cup is smaller, so as to be suitable for sucking smaller products. When the second mounting plate 25 and the third mounting plate 26 are assembled onto the suction cup, the adsorption area of the suction cup is increased, so as to be suitable for sucking larger products. That is, this embodiment can change the adsorption area of the suction cup by disassembling and assembling the second mounting plate 25 and the third mounting plate 26. Moreover, this embodiment can also adjust the adsorption area of the suction cup by adjusting the angle between the second mounting plate 25 and the first plate portion 241 and the angle between the third mounting plate 26 and the second plate portion 242, so as to adjust the size range of the products that the suction cup can suck, thereby improving the applicability of the product transferring device.

[0036] Specifically, when the second mounting plate 25 and the third mounting plate 26 are removed, the suction cup can have a minimum adsorption area. When the second mounting plate 25 and the third mounting plate 26 are assembled to the suction cup, and the angle between the second mounting plate 25 and the first plate portion 241 and the angle between the third mounting plate 26 and the second plate portion 242 are both equal to 180°, the suction cup can have a maximum adsorption area. When the second mounting plate 25 and the third mounting plate 26 are assembled to the suction cup, and the angle between the second mounting plate 25 and the first plate portion 241 and the angle between the third mounting plate 26 and the second plate portion 242 are both less than 180°, the adsorption area of the suction cup is between the minimum adsorption area and the maximum adsorption area.

[0037] For example, in this embodiment, the second mounting plate 25 and the third mounting plate 26 are assembled onto the suction cup, and the angle between the second mounting plate 25 and the first plate portion 241 and the angle between the third mounting plate 26 and the second plate portion 242 are both equal to 180°.

[0038] It is worth noting that, in this embodiment, a vent 12 and several air path interfaces 11 are provided on the connector 1, all of the air path interfaces 11 are connected to the vent 12 through an air path channel (not shown in the figure) provided inside the connector 1, and the vent 12 is connected to the air source (not shown in the figure), and several air path interfaces 11 can be connected one by one with the first suction nozzle 21, the second suction nozzle 221 and the third suction nozzle 222, so that the product can be sucked. Moreover, this embodiment can facilitate the arrangement of the air path pipeline.

[0039] In addition, it is worth mentioning that in this embodiment, the distance between the first suction nozzle 21 and the joint 1 is adjustable, so as to further increase the adjustment range of the suction area of the suction cup. Specifically, this embodiment can adjust the suction area of the suction cup by adjusting the distance between the first suction nozzle 21 and the joint 1. On this basis, this embodiment can further adjust the suction area of the suction cup by disassembling and assembling the second mounting plate 25 and the third mounting plate 26, so that the adjustment range of the suction area of the suction cup is further expanded, and the suction cup can be suitable for sucking products of more sizes. That is, this embodiment can further improve the applicability of the product transfer device.

[0040] Based on the above, in this embodiment, a first strip hole 23 is provided on both the first plate portion 241 and the second plate portion 242, and the first suction nozzle 21 is spaced apart from the joint 1 along the extension direction of the first strip hole 23, and the first suction nozzle 21 is detachably installed in the first strip hole 23, that is, this embodiment can adjust the distance between the first suction nozzle 21 and the joint 1 by adjusting the position of the first suction nozzle 21 installed in the first strip hole 23, thereby further increasing the adjustment range of the adsorption area of the suction cup.

[0041] Illustratively, in this embodiment, the first suction nozzle 21 is screwed into the first strip hole 23, the second mounting plate 25 can be screwed onto the first suction nozzle 21 installed on the first plate portion 241, and the third mounting plate 26 can be screwed onto the first suction nozzle 21 installed on the second plate portion 242.

[0042] In addition, in the present embodiment, two first strip holes 23 are provided on the first plate portion 241 and the second plate portion 242. The two first strip holes 23 are arranged at intervals along the extension direction of the first strip holes 23, so as to further increase the adjustment range of the adsorption area of the suction cup. Specifically, based on the above-mentioned content, for any one of the first plate portion 241 and the second plate portion 242, the present embodiment can adjust the distance between the first suction nozzle 21 and the joint 1 by adjusting the position of the first suction nozzle 21 installed in the first strip hole 23. On this basis, the present embodiment can also adjust the distance between the first suction nozzle 21 and the joint 1 by selectively installing the first suction nozzle 21 in one of the first strip holes 23. When a suction nozzle 21 is installed in the first strip hole 23 close to the joint 1, the suction area of the suction cup is smaller. When the first suction nozzle 21 is installed in the first strip hole 23 away from the joint 1, the suction area of the suction cup is larger. For the first suction nozzle 21 installed in any first strip hole 23, this embodiment can adjust the distance between the first suction nozzle 21 and the joint 1 by adjusting the position of the first suction nozzle 21 installed in the first strip hole 23. In summary, this embodiment can further expand the adjustment range of the suction area of the suction cup, thereby making the suction cup suitable for sucking products of more sizes, that is, this embodiment can further improve the applicability of the product transferring device.

[0043] It can be understood that in other optional embodiments, it can be arranged that more than three first strip holes 23 are provided on the first plate portion 241 and the second plate portion 242, and more than three first strip holes 23 are arranged at intervals along the extension direction of the first strip holes 23. This embodiment does not impose specific restrictions on the number of first strip holes 23 provided on the first plate portion 241 and the second plate portion 242.

[0044] Furthermore, in this embodiment, the distance between the second suction nozzle 221 and the first suction nozzle 21 is adjustable, and the distance between the third suction nozzle 222 and the first suction nozzle 21 is adjustable, thereby further increasing the adjustment range of the suction area of the suction cup. Specifically, this embodiment can adjust the suction area of the suction cup by adjusting the distance between the second suction nozzle 221 and the first suction nozzle 21 and the distance between the third suction nozzle 222 and the first suction nozzle 21, thereby further expanding the adjustment range of the suction area of the suction cup, and thus making the suction cup suitable for sucking products of more sizes, that is, this embodiment can further improve the applicability of the product transferring device.

[0045] Based on the above, the second mounting plate 25 and the third mounting plate 26 are respectively provided with a second strip hole 251 and a third strip hole 261, the second strip hole 251 extends along the arrangement direction of the first suction nozzle 21 and the second suction nozzle 221, and the second suction nozzle 221 is detachably installed in the second strip hole 251, and the third strip hole 261 extends along the arrangement direction of the first suction nozzle 21 and the third suction nozzle 222, and the third suction nozzle 222 is detachably installed in the third strip hole 261, that is, this embodiment can adjust the distance between the second suction nozzle 221 and the first suction nozzle 21 by adjusting the position of the second suction nozzle 221 installed in the second strip hole 251, and can adjust the distance between the third suction nozzle 222 and the first suction nozzle 21 by adjusting the position of the third suction nozzle 222 installed in the third strip hole 261, thereby further increasing the adjustment range of the adsorption area of the suction cup.

[0046] It is worth noting that one or more second strip holes 251 can be provided on the second mounting plate 25. When more than two second strip holes 251 are provided on the second mounting plate 25, and at least two second strip holes 251 are arranged at intervals along the extension direction of the second strip holes 251, this embodiment does not impose any specific restriction on the number of second strip holes 251 provided on the second mounting plate 25.

[0047] Correspondingly, one or more third strip holes 261 may be provided on the third mounting plate 26. When more than two third strip holes 261 are provided on the third mounting plate 26, and at least two third strip holes 261 are arranged at intervals along the extension direction of the third strip holes 261, this embodiment does not impose any specific restriction on the number of third strip holes 261 provided on the third mounting plate 26.

[0048] Furthermore, a fourth strip hole 252 is provided on the second mounting plate 25, and the fourth strip hole 252 extends along the arrangement direction of the first suction nozzle 21 and the second suction nozzle 221. The second mounting plate 25 is sleeved on the outer periphery of the first suction nozzle 21 installed on the first plate portion 241 through the fourth strip hole 252. The position of the first suction nozzle 21 installed in the fourth strip hole 252 is adjustable. Moreover, a fifth strip hole 262 is provided on the third mounting plate 26, and the fifth strip hole 262 extends along the arrangement direction of the first suction nozzle 21 and the third suction nozzle 222. The third mounting plate 26 is sleeved on the first suction nozzle installed on the second plate portion 242 through the fifth strip hole 262. 21, the position of the first suction nozzle 21 installed in the fifth strip hole 262 is adjustable, so as to further increase the adjustment range of the suction area of the suction cup. Specifically, in this embodiment, the suction area of the suction cup can be adjusted by adjusting the position of the first suction nozzle 21 installed on the first plate portion 241 installed in the fourth strip hole 252 and the position of the first suction nozzle 21 installed on the second plate portion 242 installed in the fifth strip hole 262, so that the adjustment range of the suction area of the suction cup is further expanded, and the suction cup can be suitable for sucking products of more sizes. That is, this embodiment can further improve the applicability of the product transferring device.

[0049] Based on the content mentioned above, the first suction nozzle 21 installed on the first plate portion 241 is screwed into the fourth strip hole 252, and the first suction nozzle 21 installed on the second plate portion 242 is screwed into the fifth strip hole 262. This embodiment can adjust the relative position of the second mounting plate 25 and the first plate portion 241 and the relative position of the third mounting plate 26 and the second plate portion 242 by loosening and retightening the bolts, thereby adjusting the angle between the second mounting plate 25 and the first plate portion 241 and the angle between the third mounting plate 26 and the second plate portion 242.

[0050] In addition, it should be noted that, in this embodiment, the mounting frame includes two first mounting plates 24, and the two first mounting plates 24 are cross-arranged so that the suction cup can firmly absorb and drive the product to move.

[0051] For example, in this embodiment, the included angle between the two first mounting plates 24 is equal to 90°. Of course, in other optional embodiments, the included angle between the two first mounting plates 24 may also be other angles, and this embodiment does not impose any specific limitation on this.

[0052] It is understandable that in other optional embodiments, the mounting frame can also be configured to include more than three first mounting plates 24, wherein any two first mounting plates 24 are cross-arranged. This embodiment does not impose any specific restrictions on the number of first mounting plates 24.

[0053] Example 2

[0054] like Figure 3 As shown, compared with Example 1, the difference of this embodiment is that the second mounting plate 25 and the third mounting plate 26 are assembled to the suction cup, and the angle between the second mounting plate 25 and the first plate portion 241 and the angle between the third mounting plate 26 and the second plate portion 242 are both acute angles. In addition, the distance between the second suction nozzle 221 and the joint 1 is smaller than the distance between the first suction nozzle 21 installed on the first plate portion 241 and the joint 1, and the distance between the third suction nozzle 222 and the joint 1 is smaller than the distance between the first suction nozzle 21 installed on the second plate portion 242 and the joint 1. At this time, the suction cup can maintain the minimum adsorption area, but the suction cup can absorb the product more stably.

[0055] Example 3

[0056] like Figure 4 As shown, compared with the second embodiment, the difference of this embodiment is that the angle between the two first mounting plates 24 is an acute angle, and the second mounting plate 25 is located on the downstream side of the first plate portion 241 in the clockwise direction, and the third mounting plate 26 is located on the downstream side of the second plate portion 242 in the clockwise direction.

[0057] Of course, in other optional embodiments, the second mounting plate 25 may also be located on the upstream side of the first plate portion 241 in the clockwise direction, and correspondingly, the third mounting plate 26 may also be located on the upstream side of the second plate portion 242 in the clockwise direction. This embodiment does not impose any specific restrictions on this.

[0058] Example 4

[0059] like Figure 5 As shown, compared with the third embodiment, the difference of this embodiment is that: for one of the first mounting plates 24, the second mounting plate 25 is located on the upstream side of the first plate portion 241 in the clockwise direction, and the third mounting plate 26 is located on the upstream side of the second plate portion 242 in the clockwise direction; for the other first mounting plate 24, the second mounting plate 25 is located on the downstream side of the first plate portion 241 in the clockwise direction, and the third mounting plate 26 is located on the downstream side of the second plate portion 242 in the clockwise direction.

[0060] Example 5

[0061] like Figure 6 As shown, compared with the first embodiment, the difference of this embodiment is that the angle between the second mounting plate 25 and the first plate portion 241 and the angle between the third mounting plate 26 and the second plate portion 242 are both 0°. At this time, the suction cup can have the smallest adsorption area, but the suction cup can absorb the product more stably.

[0062] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
