[0020] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0021] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0022] Please see Figure 1 , Figure 2 and Figure 3 The material handling device 100 includes a mounting plate 1, a suction assembly 2, a snap-fit assembly 3, a cylinder fixing component 4, and a cylinder movable component 5. The cylinder movable component 5 is detachably mounted on the cylinder fixing component 4. The snap-fit assembly 3 is mounted on the mounting plate 1, and the mounting plate 1 is removably snapped onto the aforementioned cylinder movable component 5 via the snap-fit assembly 3. The suction assembly 2 is mounted on the mounting plate 1, and the suction assembly 2 is used to pick up materials.
[0023] For the mounting plate mentioned above, please refer to... Figure 2 and Figure 3 The mounting plate 1 is provided with an air extraction channel 111 and multiple branch channels 112. The multiple branch channels 112 are all connected to the air extraction channel 111. The material suction assembly 2 is connected to the multiple branch channels 112. The air extraction channel 111 is configured to be connected to the air pump 500 so that the air pump 500 can sequentially form a negative pressure in the material suction assembly 2 through the air extraction channel 111 and the multiple branch channels 112, so that the material suction assembly 2 can suck up the material.
[0024] For the aforementioned snap-fit component 3, please refer to... Figure 4 and Figure 6 The snap-fit assembly 3 includes a snap-fit member 31, a rotating shaft 32, and an elastic member 33. The rotating shaft 32 is inserted into the mounting plate 1 and passes through the snap-fit member 31. The snap-fit member 31 can rotate around the rotating shaft 32, realizing a rotational connection between the snap-fit member 31 and the rotating shaft 32. The snap-fit member 31 is configured to snap-fit with the cylinder movable member 5. One end of the elastic member 33 abuts against the snap-fit member 31, and the other end abuts against the mounting plate 1. The elastic member 33 is used to undergo elastic deformation so that the snap-fit member 31 can remain snap-fit with the cylinder movable member 5, thereby keeping the mounting plate 1 snap-fit with the cylinder movable member 5. When the snap-fit member 31 is subjected to external force, the snap-fit member 31 can overcome the elastic force of the elastic member 33 and rotate around the rotating shaft 32, thereby canceling the snap-fit between the snap-fit member 31 and the cylinder movable member 5. At this time, the mounting plate 1 can separate from the cylinder movable member 5. It is worth noting that during the production process, different specifications of suction components 2 are usually required for products of the same type but different models or different types of products. Therefore, in this embodiment, the mounting plate 1 and the cylinder movable part 5 are connected by the snap-fit component 3, which makes the assembly or disassembly of the mounting plate 1 and the cylinder movable part 5 simple and convenient. When replacing the suction component 2, the replacement efficiency can be improved and the difficulty of the replacement operation can be reduced.
[0025] In some embodiments, please refer to Figure 4 and Figure 6 The mounting plate 1 is provided with a slot 116 at one end away from the suction assembly 2. At least a portion of the cylinder movable part 5 is received in the slot 116. The aforementioned snap-fit assembly 3 is used to snap-fit with the portion of the cylinder movable part 5 received in the slot 116, thereby fixing the mounting plate 1 to the cylinder movable part 5.
[0026] In some embodiments, the mounting plate 1 is provided with a mounting groove 117, and a rotating shaft 32 is disposed on the mounting plate 1, with at least a portion of the rotating shaft 32 inserted through the mounting groove 117. At least a portion of the snap-fit member 31 is received in the mounting groove 117, and the portion of the rotating shaft 32 received in the mounting groove 117 passes through the snap-fit member 31, allowing the snap-fit member 31 to rotate about the rotating shaft 32. When the snap-fit member 31 is in the first position, please refer to... Figure 6 The snap-fit component 31 snaps into the cylinder movable component 5; when the snap-fit component 31 rotates to the second position, please refer to... Figure 7 When the snap-fit 31 is disconnected from the cylinder movable part 5, the mounting plate 1 can be separated from the cylinder movable part 5, thereby disassembling the suction cup device 100.
[0027] In some embodiments, please refer to Figure 4 and Figure 6The mounting plate 1 includes a mounting body 11 and a limiting member 12. The aforementioned air extraction channel 111, multiple branch channels 112, slot 116, and mounting groove 117 are all disposed on the mounting body 11. The limiting member 12 is disposed on the mounting body 11 and covers at least a portion of the mounting groove 117 along the third direction Z. One end of the elastic member 33 abuts against the snap-fit member 31, and the other end abuts against the limiting member 12, so that the elastic member 33 can hold the snap-fit member 31 in a first position, thereby keeping the snap-fit member 31 snapped into the cylinder moving member 5. In this embodiment, the mounting plate 1 includes a mounting body 11 and a limiting member 12. During the assembly of the suction device 100, the aforementioned rotating shaft 32 and snap-fit member 31 can be installed in the mounting groove 117 of the mounting body 11 first. Then, the elastic member 33 is inserted into the mounting groove 117 along the limiting groove 1173. Finally, the limiting member 12 is installed on the mounting body 11, so that the elastic member 33 abuts against the part of the limiting member 12 exposed in the mounting groove 117. On the one hand, this can provide a force point for the elastic member 33, allowing the elastic member 33 to deform. On the other hand, it can restrict the elastic member 33 from disengaging from the mounting groove 117 along the third direction Z.
[0028] In some embodiments, please refer to Figure 6 The snap-fit member 31 includes a connecting portion 311 and a snap-fit portion 312. At least a portion of the connecting portion 311 is received in a mounting groove 117. A rotating shaft 32 passes through the connecting portion 311, and the connecting portion 311 is rotatable about the rotating shaft 32. The snap-fit portion 312 is disposed at one end of the connecting portion 311 and is configured to snap-fit with the cylinder movable member 5. Specifically, when the snap-fit member 31 is in a first position, at least a portion of the snap-fit portion 312 is received in a retaining groove 116 along the third direction Z, so that the snap-fit portion 312 is snap-fitted and fixed with the portion of the cylinder movable member 5 received in the retaining groove 116. When the snap-fit member 31 is in a second position, please refer to... Figure 7 Along the third direction Z, the snap-fit portion 312 is received in the mounting groove 117 and is located outside the snap-fit groove 116, thereby separating the snap-fit portion 312 from the cylinder moving part 5 and canceling the fixation between the mounting plate 1 and the cylinder moving part 5.
[0029] In some embodiments, the snap-fit member 31 further includes a pressing portion 313, which is disposed at the end of the connecting portion 311 away from the snap-fit portion 312 and along the third direction Z. The pressing portion 313 and the snap-fit portion 312 are respectively located on both sides of the connecting portion 311, so that the snap-fit member 31 is generally Z-shaped. When the snap-fit member 31 is in the first position, at least a portion of the pressing portion 313 protrudes beyond the mounting groove 117. The user can press the pressing portion 313 to rotate the snap-fit member 31 from the first position to the second position, thereby canceling the snap-fit between the snap-fit member 31 and the cylinder movable member 5.
[0030] In some embodiments, please refer to Figure 4 The first sidewall 1171 of the mounting groove 117 is provided with a limiting groove 1173. The limiting groove 1173 is recessed from the first sidewall 1171 in a direction away from the second sidewall 1172, so that the width of the mounting groove 117 at the limiting groove 1173 is greater than the width of the mounting groove 117 at other positions. The first sidewall 1171 and the second sidewall 1172 are arranged opposite to each other. The elastic member 33 is at least partially received in the limiting groove 1173, and the portion of the elastic member 33 protruding from the limiting groove 1173 abuts against the second sidewall 1172. Thus, the first sidewall 1171 and the second sidewall 1172 can jointly restrict the movement of the elastic member 33 along the second direction Y, which is parallel to the arrangement direction of the first sidewall 1171 and the second sidewall 1172. In addition, since the width of the mounting groove 117 at the limiting groove 1173 is greater than the width of the mounting groove 117 at other positions, the movement of the elastic member 33 along the first direction X is restricted. In this way, during the operation of the limiting member 12 to rotate, the risk of the elastic member 33 being displaced and thus separating from the snap-fit member 31 can be reduced. The first direction X is parallel to the arrangement direction of the mounting plate 1 and the cylinder moving member 5, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.
[0031] In some embodiments, the minimum distance between the first sidewall 1171 and the second sidewall 1172 is slightly greater than the size of the snap-fit member 31 in the second direction Y, so that the snap-fit member 31 can rotate around the rotation axis 32 in the mounting groove 117 without the gap being too large and causing wobbling, which is beneficial to improving the stability of the connection between the cylinder moving part 5 and the mounting plate 1.
[0032] In some embodiments, the outer diameter of the elastic member 33 is larger than the size of the snap fastener 31 in the second direction Y, so that the elastic member 33 can be pressed against the snap fastener 31, and the risk of the elastic member 33 dislodging from the predetermined position as the snap fastener 31 rotates can be reduced.
[0033] In some embodiments, please refer to Figure 6 There are two snap-fit components 3, which are distributed opposite each other along the third direction Z. One snap-fit component 3 is located at one end of the mounting plate 1, and the other snap-fit component 3 is located at the other end of the mounting plate 1. The two snap-fit components 3 are configured to snap together with the cylinder moving part 5, thereby improving the stability of the fixation between the mounting plate 1 and the cylinder moving part 5.
[0034] Specifically, the mounting body 11 is provided with two mounting slots 117 along the third direction Z. The two mounting slots 117 are respectively opened at both ends of the mounting body 11, and both mounting slots 117 are connected to the slots 116. The number of limiting members 12 corresponds to the number of mounting slots 117. One limiting member 12 covers a portion of one mounting slot 117 along the third direction Z. One end of an elastic member 33 abuts against the snap-fit member 31, and the end of the elastic member 33 away from the snap-fit member 31 abuts against the corresponding limiting member 12. When the cylinder movable member 5 is inserted into the slot 116, the snap-fit members 31 of the two snap-fit components 3 can be snapped onto both sides of the cylinder movable member 5, thereby snapping and fixing the mounting body 11 and the cylinder movable member 5. In this embodiment, by providing two mounting slots 117 on the mounting body 11, with the two mounting slots 117 located at both ends of the mounting body 11 along the third direction Z, and by providing two snap-fit components 3 in the two mounting slots 117, the two snap-fit components 3 can jointly snap-fit the two ends of the cylinder moving part 5, which is beneficial to improving the stability of the connection between the mounting plate 1 and the cylinder moving part 5.
[0035] It is worth noting that the two snap-fit components 3 are symmetrically arranged on the mounting body 11 along the third direction Z. For the specific structure of the two snap-fit components 3, please refer to the above embodiments. This application will not describe the specific structure of the two snap-fit components 3 one by one.
[0036] In some embodiments, please refer to Figure 4 and Figure 6 The material suction assembly 2 includes multiple mounting shafts 21 and multiple suction cups 22. Each mounting shaft 21 and suction cup 22 is configured as a set, and each set is correspondingly arranged in a branch channel 112. The mounting shaft 21 is partially inserted into the corresponding branch channel 112, and the suction cup 22 is mounted on the portion of the corresponding mounting shaft 21 that protrudes from the branch channel 112. The suction cup 22 is connected to the branch channel 112 through the mounting shaft 21, so that the air pump 8 can create a negative pressure in the corresponding suction cup 22 through the air extraction channel 111, the branch channel 112, and the mounting shaft 21, so that the suction cup 22 can pick up the material. In this embodiment, by setting multiple mounting shafts 21 and multiple suction cups 22, during material picking, one suction cup 22 picks up one material, so that the material picking device 100 can pick up multiple materials at the same time, which greatly improves the material picking efficiency of the material picking device 100.
[0037] In some embodiments, the mounting shaft 21 is provided with a suction channel 24, which extends through the mounting shaft 21 along a first direction X and is connected to the branch channel 112. When the air pump 8 is working, the air pump 8 can sequentially create a negative pressure on the suction cup 22 through the suction channel 111, the branch channel 112 and the suction channel 24, thereby adsorbing the material onto the suction assembly 2 for easy material transfer.
[0038] In some embodiments, the suction assembly 2 includes a plurality of first sealing rings 23. A first sealing ring 23 is sleeved on a mounting shaft 21 and abuts against the mounting plate 1. Along the first direction X, the first sealing ring 23 covers the gap between the mounting shaft 21 and the branch channel 112, thereby achieving a seal between the mounting shaft 21 and the corresponding branch channel 112, reducing the risk of air entering the branch channel 112 from the gap between the mounting shaft 21 and the branch channel 112 during the material suction process, and improving the stability of the suction cup 22 when suctioning materials.
[0039] In some embodiments, please refer to Figure 4 and Figure 6 The material handling device 100 also includes multiple screw connectors 6. The mounting plate 1 has multiple screw holes 114, one of which communicates with the side wall of a branch channel 112, and the axis of the screw hole 114 is not parallel to the axis of the branch channel 112. A screw connector 6 is screwed into a screw hole 114, and the screw connector 6 is configured to abut against the portion of the mounting shaft 21 inserted into the branch channel 112, thereby restricting the movement of the mounting shaft 21 along the axial direction of the branch channel 112. It is worth noting that when the screw connector 6 is loosened, the suction assembly 2 can slide along the axis of the branch channel 112, thereby adjusting the height difference of the multiple suction cups 22 in the first direction X, which is beneficial for the material handling device 100 to simultaneously pick up multiple materials. For the cylinder moving part 5 mentioned above, please refer to... Figure 6 The cylinder movable component 5 is equipped with an air path conversion pipe 51. When the mounting plate 1 is snapped into the cylinder movable component 5 via the snap-fit assembly 3, the air path conversion pipe 51 is inserted into the suction channel 111, thereby connecting the air path conversion pipe 51 with the suction channel 111. The material handling device 100 also includes an air pump 8, which is connected to the air path conversion pipe 51, so that the air pump 8 can sequentially pass through the air path conversion pipe 51, the suction channel 111, the branch channel 112, and the suction channel 24 to form a negative pressure in the suction cup 22, thereby adsorbing materials. In this embodiment, by setting the air path conversion pipe 51, when the mounting plate 1 is installed onto the cylinder movable component 5, the air path conversion pipe 51 can be inserted into the suction channel 111, thereby realizing the connection between the air pump 8 and the suction channel 111. There is no need to manually connect the air pump 8 to the suction channel 111, making the operation simple and convenient.
[0040] In some embodiments, the material handling device 100 further includes a second sealing ring 7, which is sleeved on the air path conversion pipe 51. When the suction cup device 100 is engaged with the cylinder movable part 5, the second sealing ring 7 is located in the air extraction channel 111, thereby sealing the gap between the air path conversion pipe 51 and the air extraction channel 111 and reducing the risk of air entering the air extraction channel 111 from the gap between the air path conversion pipe 51 and the air extraction channel 111.
[0041] In some embodiments, a retaining plate 52 is provided at one end of the cylinder movable component 5 facing the mounting plate 1. When the cylinder movable component 5 is inserted into the retaining groove 116 and the retaining member 31 is in the first position, the retaining part 312 engages with the side of the retaining plate 52 away from the suction assembly 2, thereby restricting the cylinder movable component 5 from disengaging from the retaining groove 116 along the first direction X, thus achieving a retaining fixation between the mounting plate 1 and the cylinder movable component 5. When the retaining member 31 is in the second position, please refer to [reference needed]. Figure 7 Along the first direction X, the projection of the latching part 312 and the projection of the latching table 52 are offset from each other. At this time, the mounting plate 1 can move relative to the cylinder moving part 5 along the first direction X so that the mounting plate 1 and the cylinder moving part 5 are separated from each other.
[0042] In some embodiments, there are two locking platforms 52, which are arranged opposite each other along the third direction Z. One locking component 3 is used to lock with one locking platform 52, and the other locking component 3 is used to lock with the other locking platform 52, thereby improving the stability of the connection between the mounting plate 1 and the cylinder moving part 5.
[0043] In some embodiments, please refer to Figure 2 The cylinder moving part 5 is provided with a positioning pin 53, and the mounting plate 1 is provided with a positioning hole 118. The positioning pin 53 is used to insert and cooperate with the positioning hole 118. On the one hand, it realizes the positioning between the cylinder moving part 5 and the mounting plate 1. On the other hand, since the air circuit conversion pipe 51 is inserted into the air extraction channel 111, and the positioning pin 53 and the positioning hole 118 are connected together, the rotation of the mounting plate 1 around the air circuit conversion pipe 51 can be restricted, thereby improving the stability of the fixed position between the mounting plate 1 and the cylinder moving part 5.
[0044] In some embodiments, the positioning hole 118 is generally waist-shaped, and the size of the positioning hole 118 in the third direction Z is larger than its size in the second direction Y, which facilitates the smoother insertion of the positioning pin 53 into the positioning hole 118.
[0045] In this embodiment, the mounting plate 1 and the cylinder movable part 5 are connected by the snap-fit component 3, so that different mounting plates 1, snap-fit components 3 and suction components 2 can be switched for different products to meet the needs of frequent switching of suction components 2 in the production process; and the assembly or disassembly between the mounting plate 1 and the cylinder movable part 5 is simple and convenient, which can improve the replacement efficiency and reduce the difficulty of replacement operation when replacing suction components 2.
[0046] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
