[0023] In order to enable those skilled in the art to better understand the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0024] In this article, terms such as "upper, lower, inside, outside" are established based on the positional relationships shown in the drawings. Depending on the different drawings, the corresponding positional relationships may also change accordingly. Therefore, they cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" are only used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0025] Example 1

[0026] like Figure 1 As shown, the logistics suction cup module for sucking inclined packages disclosed in this embodiment includes a mounting frame 1, a lifting component 2 installed on the mounting frame 1, and at least one suction cup mechanism 3 installed on the lifting component 2. The suction cup mechanism 3 includes a deflection component 31 installed on the lifting component 2 and a suction cup component 32 hinged to the deflection component 31; wherein, the lifting component 2 drives the suction cup mechanism 3 to move back and forth up and down along the mounting frame 1, and the deflection component 31 drives the suction cup component 32 to deflect.

[0027] Specifically, the deflection of the suction cup assembly 32 is driven by the provision of the deflection assembly 31, so that the deflection of the suction cup assembly 32 is achieved, so that the suction cup assembly 32 can be tilted at a certain angle to adapt to the tilted package, thereby facilitating the adsorption of the tilted package; and the tilted suction cup assembly 32 can fit the tilted package surface to avoid air leakage, thereby ensuring the adsorption strength of the suction cup assembly 32 on the package, preventing the package from falling off the suction cup assembly 32, and ensuring the safety of the package separation or transportation process.

[0028] More specifically, during the operation of the logistics suction cup module, the suction cup mechanism 3 can be controlled to move downward as a whole through the lifting component 2. After the suction cup component 32 approaches the package to be adsorbed, the suction cup component 32 is driven by the deflection component 31 to deflect toward the package until it is adapted to the surface of the package (adaptation here means that the adsorption end of the suction cup component 32 is roughly parallel to the surface of the package). After the suction cup component 32 is in contact with the surface of the package, the suction cup component 32 adsorbs the package with the help of a vacuum generator (not shown in the figure); wherein, the deflection angle of the suction cup component 32 can also be adjusted first, and then the lifting and lowering of the suction cup component 32 can be completed. There is no restriction on the specific order of use, as long as effective adsorption of the package can be achieved. It can be understood that in order to improve the degree of automation of the logistics suction cup module, it can be used in conjunction with a visual inspection module. The visual inspection module can feedback the tilt angle of the package and the approximate data of the package so that the deflection component 31 can adjust the deflection angle of the suction cup component 32. The visual inspection module belongs to the existing technology and will not be described in detail here. In addition, the connection form and usage principle of the vacuum generator and the suction cup component 32 all belong to the existing technology and will not be described in detail here.

[0029] Furthermore, if Figure 1 、 Figure 3 and Figure 4 As shown, the deflection assembly 31 includes a hinge seat 311 and a deflection drive 312, the suction cup assembly 32 is hinged to the hinge seat 311, the deflection drive 312 is installed on the hinge seat 311 and its output end is connected to the suction cup assembly 32; the deflection drive 312 drives the suction cup assembly 32 to deflect relative to the hinge seat 311, so as to adjust the deflection angle of the suction cup assembly 32; as an implementable embodiment, the suction cup assembly 32 can achieve deflection in two directions to increase the deflection range of the suction cup assembly 32, thereby increasing the working range of the suction cup assembly 32; as an implementable embodiment, the deflection drive 312 is a bidirectional drive, that is, it can achieve deflection in two directions of the suction cup assembly 32.

[0030] Furthermore, if Figure 1 and Figure 3 As shown, the suction cup assembly 32 includes a connecting seat 321 and a suction cup 322. The connecting seat 321 is hinged to the hinge seat 311 through a connecting shaft 313. The side of the suction cup 322 used to adsorb the package is the adsorption end. As an implementable embodiment, the suction cup 322 is connected to the connecting seat 321 in a detachable connection manner, so that the suction cup 322 of different structures and sizes can be replaced according to different package types, and it is also convenient to replace the damaged suction cup 322.

[0031] Furthermore, if Figure 3 and Figure 5 As shown, the lifting assembly 2 includes a lifting drive 21 mounted on the mounting frame 1 and at least one set of sliding structures 22. The sliding structures 22 correspond one-to-one with the suction cup mechanism 3. The sliding structures 22 include a guide rail 221 mounted on the mounting frame 1 and a slider 222 that slides with the guide rail 221. The output end of the lifting drive 21 is connected to the slider 222. The slider 222 is connected to the deflection assembly 31 of the suction cup mechanism 3 via a fixed plate 4. The fixed plate 4 connects the slider 222 to the hinge seat 311 of the deflection assembly 31. The slider 222 cooperates with the guide rail 221. Driven by the lifting drive 21, the slider 222 slides up and down along the guide rail 221, thereby driving the deflection assembly 31 and the suction cup assembly 32 to move up and down. The sliding structures 22 can be provided in one or more sets, depending on the actual situation.

[0032] Furthermore, the lifting drive 21 adopts any one of an electric telescopic rod, an air cylinder or an oil cylinder; or Figure 1-3As shown, the lifting drive 21 adopts a rotary motor, and a driving wheel 23 and a driven wheel 24 are installed on the mounting frame 1 at vertical intervals. The driving wheel 23 and the driven wheel 24 are connected by a synchronous belt 25, and the output end of the rotary motor is connected to the driving wheel 23, and the slider 222 is connected to the synchronous belt 25 by a connecting plate 26; specifically, the output end of the rotary motor drives the driving wheel 23 to rotate, and the driving wheel 23 drives the driven wheel 24 to rotate through the synchronous belt 25. At this time, the slider 222 connected to the synchronous belt 25 rises or falls with the rotation of the synchronous belt 25 to realize the rising or falling of the suction cup assembly 32; it can be understood that the rotary motor adopts a bidirectional motor to realize the up and down reciprocating movement of the slider 222.

[0033] Furthermore, if Figure 6 As shown, a drag chain 7 is provided on the mounting frame 1, and / or a drag chain 7 is installed on the fixing plate 4; the pipelines are collected and organized by the drag chain 7, so that when the suction cup assembly 32 moves up and down relative to the mounting frame 1, the pipelines also move within a limited space, thereby preventing the pipelines from being entangled and avoiding the pipelines from interfering with the suction cup assembly 32; wherein, the specific installation position and number of the drag chain 7 can be selected according to actual conditions, and no specific restrictions are made here, as long as the collection and organization of the pipelines can be achieved.

[0034] Example 2

[0035] The same parts in this embodiment as those in the first embodiment are given the same reference numerals, and the same text descriptions are omitted.

[0036] Compared with the first embodiment, the logistics suction cup module for sucking inclined packages provided in this embodiment has a different structural design: Figure 3 and Figure 4As shown, the deflection drive 312 includes a drive motor mounted on the hinge seat 311; wherein, the output end of the drive motor is engaged with the connecting seat 321 through the gear 33 for transmission, and the drive motor drives the connecting seat 321 to deflect relative to the connecting shaft 313, and the deflection of the connecting seat 321 drives the suction cup 322 to deflect; and the gear 33 is engaged and driven to improve the stability of the transmission; as an embodiment, the drive motor adopts a bidirectional motor to realize the deflection of the suction cup assembly 32 in two directions and to realize the deflection reset. It is understandable that the drive motor can also adopt other forms to drive the deflection of the suction cup assembly 32, for example: the output end of the drive motor is connected to the connecting shaft 313, and the drive motor drives the connecting shaft 313 to rotate to drive the suction cup assembly 32 to deflect. Of course, the deflection drive 312 may also employ other structures. For example, the deflection drive 312 may include a telescopic power source mounted on the hinge seat 311, with the output end of the telescopic power source connected to the connecting seat 321. The telescopic power source is retracted to drive the connecting seat 321 to deflect relative to the connecting shaft 313. The telescopic power source may be an electric telescopic rod, a pneumatic cylinder, or an oil cylinder. The specific structure and form of the deflection drive 312 are not limited, as long as it can drive the suction cup assembly 32 to deflect and reset.

The two sliders 222 are respectively connected to the synchronous belt 25 on both sides of the driving wheel 23, and the running directions of the two sliders 222 are opposite; since the two sliders 222 are installed on both sides of the driving wheel 23 of the synchronous belt 25, when the synchronous belt 25 rotates, the running directions of the two sliders 222 are opposite, thereby driving the running directions of the two suction cup mechanisms 3 in opposite directions. According to the size and position of the package, the appropriate suction cup mechanism 3 is selected to adsorb the package, thereby improving the convenience of using the logistics suction cup module, and by setting two suction cup mechanisms 3 with opposite running directions, the two suction cup mechanisms 3 can perform continuous operation, thereby improving the working efficiency of the logistics suction cup module.

[0043] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.
