Description

Detailed Implementation

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] The core of this utility model is to provide a suction cup clamp that achieves the rotation of the suction cup assembly and the workpiece through a push-pull component, so as to meet the rotation requirements during transfer and stacking, and can be applied to the transfer and stacking of long strip workpieces.

[0045] The suction cup clamp provided by this utility model includes a bracket assembly 01, a suction cup assembly 03, a push-pull assembly 02, and control elements. Please refer to [reference needed]. Figure 2 , Figure 3 .

[0046] The bracket assembly 01 has a mounting part 5, which is connected to a transfer component to realize the transfer of the entire suction cup clamp. For example, the transfer component can be the robot body, which can drive the suction cup clamp to move in multiple directions to realize the handling and transfer of workpieces.

[0047] The specific structure of the mounting section 5 and the transfer components can be matched and set up to facilitate connection; there are no restrictions here.

[0048] The suction cup assembly 03 is rotatably connected to the bracket assembly 01 and is used to adsorb the workpiece 16. The workpiece 16 can be a long strip workpiece, such as a corner column in the automated production of container houses, or a long strip workpiece in other fields that needs to be transferred and stacked.

[0049] In one specific embodiment, the suction cup assembly 03 and the bracket assembly 01 are rotatably connected by a rotating shaft. To ensure the smooth and reliable rotation of the suction cup assembly 03, a bearing can be provided in conjunction with the rotating shaft.

[0050] The push-pull assembly 02 is connected to the suction cup assembly 03. This connection is fixed to ensure reliability when the push-pull assembly 02 pushes and pulls the suction cup assembly 03 to rotate. Specifically, the push-pull assembly 02 has a first preset state and a second preset state.

[0051] In the first and second preset states of the push-pull assembly 02, the corresponding suction cup assembly 03 rotates relative to the bracket assembly 01. A control element signal is connected to the push-pull assembly 02 to switch between the first and second preset states.

[0052] In one specific implementation, either the first preset state or the second preset state is... Figure 3 The state of the push-pull assembly 02 is one of pushing or pulling the suction cup assembly 03 to rotate around the bracket assembly 01. If the workpiece 16 needs to change its posture when being attracted, the push-pull assembly 02 is switched between a first preset state and a second preset state by the control element to realize the rotation of the suction cup assembly 03 and the workpiece 16 relative to the bracket assembly 01.

[0053] After the workpiece 16 is successfully adsorbed, the workpiece 16 is kept in the state when it was adsorbed (the push-pull component 02 may be in the first preset state or the second preset state) and placed at the stacking position.

[0054] In another specific implementation, the first preset state is: Figure 3 The second preset state of the push-pull assembly 02 is that it pushes or pulls the suction cup assembly 03 to rotate around the bracket assembly 01. If the workpiece 16 does not need to change its posture during adsorption, the push-pull assembly 02 is controlled by the control element to operate in the first preset state. During the transfer of the workpiece 16, the original first preset state of the push-pull assembly 02 is maintained. Upon reaching the stacking position, if the workpiece 16 needs to rotate to facilitate placement in a confined space, the push-pull assembly 02 is controlled by the control element to switch from the first preset state to the second preset state. Of course, if the workpiece 16 can be placed without rotation upon reaching the stacking position, the push-pull assembly 02 can maintain its original first preset state throughout the entire process.

[0055] In another specific implementation, the first preset state is: Figure 3 The middle push-pull assembly 02 rotates clockwise by a certain angle relative to the bracket assembly 01, and the second preset state is... Figure 3 The push-pull assembly 02 is in a state where it has rotated counterclockwise by a certain angle relative to the bracket assembly 01. The clockwise and counterclockwise rotations here can be referenced accordingly. Figure 2The dashed and solid arrows are shown in the diagram. When the workpiece 16 is adsorbed and placed, the push-pull assembly 02 can maintain a first preset state, a second preset state, or switch between the first and second preset states, allowing for flexible selection based on the actual needs of adsorbing and stacking the workpiece 16.

[0056] In this embodiment, the push-pull assembly 02 can specifically be a linkage assembly and a cylinder, or a moving assembly (including a motor and a transmission component) and a linkage assembly. Specifically, both the cylinder and the moving assembly are used to move and push or pull the linkage assembly, so as to further act on the suction cup assembly 03 and realize the rotation of the suction cup assembly 03.

[0057] Taking the configuration of motor, transmission component, and linkage assembly as an example, the output end of the motor is connected to the transmission component, which converts the rotational force of the motor into a translational force. The transmission component is connected to the linkage assembly, and the forward and reverse rotation of the motor realizes the pulling and pushing of the linkage assembly, so that the linkage assembly can transmit the pushing and pulling force to the suction cup assembly 03, thereby realizing the rotation of the suction cup assembly 03 and the workpiece 16 relative to the bracket assembly 01.

[0058] Taking the connecting rod assembly and cylinder as an example, the cylinder extends and retracts to transmit the push and pull force to the connecting rod assembly, which further transmits it to the suction cup assembly 03, thereby realizing the rotation of the suction cup assembly 03 and the workpiece 16 relative to the bracket assembly 01.

[0059] Based on the above embodiments, the push-pull assembly 02 includes:

[0060] Push plate 4, fixedly connected to suction cup assembly 03;

[0061] The push-pull cylinder 3 has a first preset state in which the cylinder rod end of the push-pull cylinder 3 is retracted, and a second preset state in which the cylinder rod end of the push-pull cylinder 3 is extended. The cylinder barrel end of the push-pull cylinder 3 is hinged to the bracket assembly 01, and the cylinder rod end of the push-pull cylinder 3 is hinged to the push plate 4. The control element controls the extension and retraction of the push-pull cylinder 3 to realize the switching of the push-pull assembly 02 between the first preset state and the second preset state.

[0062] Please refer to Figure 2 , Figure 3 , Figure 4 The push-pull assembly 02 specifically includes a push plate 4 and a push-pull cylinder 3.

[0063] The push plate 4 is fixedly connected to the suction cup assembly 03. The push-pull cylinder 3 pushes or pulls the suction cup assembly 03 through the push plate 4, so that the suction cup assembly 03 rotates relative to the bracket assembly 01, and the movement is stable and precise.

[0064] The control element controls the extension and retraction of the push-pull cylinder 3 to switch the push-pull assembly 02 between a first preset state and a second preset state. The specific extension and retraction amount of the push-pull cylinder 3 can be determined according to the actual situation.

[0065] The first preset state of the push-pull cylinder 3 is its retracted state, and the second preset state is its extended state. The extension and retraction of the push-pull cylinder are controlled by a control element to control the rotation of the suction cup assembly 03. Specifically, when the cylinder rod of the push-pull cylinder 3 extends, the pushing plate 4 transfers the pushing force to the suction cup assembly 03, causing the suction cup assembly 03 to rotate counterclockwise relative to the bracket assembly 01, thereby driving the workpiece 16 to rotate to the upper right. The specific direction of rotation is... Figure 2 The direction indicated by the solid line arrow.

[0066] When the cylinder rod of the push-pull cylinder 3 retracts, the force is transferred to the suction cup assembly 03 via the push plate 4, causing the suction cup assembly 03 to rotate clockwise relative to the bracket assembly 01, thereby driving the workpiece 16 to rotate to the upper left. The specific direction of rotation is as follows: Figure 2 The direction indicated by the dashed arrow.

[0067] The cylinder end of the push-pull cylinder 3 is hinged to the bracket assembly 01, and the cylinder rod end of the push-pull cylinder 3 is hinged to the push plate 4, so that the push-pull cylinder 3 has greater flexibility when extending or retracting, and the movement is stable, avoiding cylinder damage or component collisions caused by rigid connection.

[0068] Based on any of the above embodiments, the cylinder end is connected to the middle of the bracket assembly 01, and the push plate 4 is connected to the middle of the suction cup assembly 03.

[0069] Please refer to Figure 1 , Figure 2 , Figure 3 A set of push-pull components 02 is set up, and the suction cup component 03 is pushed and pulled by a push-pull cylinder 3. This facilitates the wiring arrangement of the push-pull cylinder 3. The push-pull cylinder 3 and the suction cup component 03 can share the same air source.

[0070] Specifically, the cylinder end of the push-pull cylinder 3 is connected to the middle of the bracket assembly 01, the cylinder rod end of the push-pull cylinder 3 is connected to the push plate 4, and the push plate 4 is connected to the middle of the suction cup assembly 03, so as to ensure the stability of the overall structure during the push-pull operation and ensure the reliable and stable rotation of the suction cup assembly 03.

[0071] Based on any of the above embodiments, multiple sets of push-pull components 02 are arranged along the length direction of the bracket assembly 01, and multiple push-pull cylinders 3 are arranged in parallel in the extension and retraction directions.

[0072] If the workpiece 16 is heavy or the suction cup assembly 03 is heavy overall, a single cylinder cannot reliably push or pull it. Therefore, multiple cylinders are needed. That is, multiple sets of push-pull components 02 are arranged along the length of the bracket assembly 01. When the suction cup assembly 03 needs to rotate the workpiece 16, multiple cylinders extend or retract simultaneously to achieve the push-pull effect of the suction cup assembly 03. Here, the length direction is... Figure 2 The X-direction in the middle.

[0073] The multiple push-pull components 02 are preferably arranged at equal intervals, and the extension and retraction directions of the multiple push-pull cylinders 3 are arranged in parallel to ensure the overall stability of the suction cup clamp and avoid affecting the overall center of gravity.

[0074] While meeting usage requirements, the push-pull component 02 should not be set too many times; just enough to meet the needs, to avoid excessive wiring affecting the components on the entire suction cup clamp.

[0075] Based on any of the above embodiments, a limiting component is movably provided on the bracket assembly 01 to limit the rotation angle of the suction cup assembly 03 relative to the bracket assembly 01.

[0076] The limiting component has at least two fixed points on the bracket assembly 01.

[0077] Please refer to Figure 2 , Figure 3 The bracket assembly 01 is equipped with a limit component. This limit component has at least two fixed points in the height direction of the bracket assembly 01, corresponding to two extreme angles that can be limited according to actual conditions. The height direction is... Figure 2 The Z-direction in the middle.

[0078] For example, the suction cup assembly 03 needs to be rotated to a larger angle to place the workpiece 16, and the suction cup assembly 03 needs to be rotated to a smaller angle to adsorb the workpiece 16, which corresponds to two different limiting angles.

[0079] If the limiting angles corresponding to different types of workpieces 16 are not consistent, the fixed points connected to the limiting components on the bracket assembly 01 can be changed to make adaptive changes and improve the adaptability and flexibility of the suction cup fixture.

[0080] The limiting component is used to limit the rotation angle of the suction cup assembly 03 relative to the bracket assembly 01. Taking one specific embodiment as an example, when the suction cup assembly 03 rotates into the limiting space of the limiting component, the push-pull component 02 stops working to avoid collision between the components, so as to play a limiting role.

[0081] The rotation of the suction cup assembly 03 into the limiting space of the limiting assembly can be determined by setting a proximity switch, or by setting an angle monitor to monitor the rotation angle of the suction cup assembly 03, as long as the limiting effect of the rotation of the suction cup assembly 03 can be achieved.

[0082] In one specific embodiment, the limiting component can be provided on one side or both sides of the suction cup component 03. If only counterclockwise rotation is required, the limiting component restricting counterclockwise rotation can be provided on only one side. If only clockwise rotation is required, the limiting component restricting clockwise rotation can be provided on only one side. If both clockwise and counterclockwise rotation are required, the limiting component can be provided on both sides.

[0083] In this embodiment, the limiting component moves on the bracket assembly 01 and connects to any one of at least two fixed points. This can be achieved by setting a sliding groove for the limiting component to slide or by setting multiple connecting holes for the limiting component to connect. To facilitate the operator's understanding of the limiting angle corresponding to each fixed point, a scale or mark can be set on the bracket assembly 01.

[0084] Based on any of the above embodiments, the bracket assembly 01 is a rectangular structure, and the axis along the length of the rectangular structure is the pivot of the suction cup assembly 03.

[0085] The limiting component is a limiting block 15 fixed in the height direction of the rectangular structure and located on the rotation path of the suction cup assembly 03. The suction cup assembly 03 contacts the limiting block 15 to achieve the limiting.

[0086] Please refer to Figure 2 , Figure 3 The bracket assembly 01 has a rectangular structure, and the axis along the length of the rectangular structure is the pivot of the suction cup assembly 03. The length of the rectangular structure is... Figure 2 In the X-axis direction.

[0087] The limiting component is specifically fixed in the height direction of bracket assembly 01. Figure 2 The limiting block 15 is located on the Z-axis direction of the suction cup assembly 03 and is situated on the rotation path of the suction cup assembly 03. The limiting block 15 starts from the side beam 2 of the bracket assembly 01 and extends towards the suction cup assembly 03. There is a distance between the suction cup assembly 03 and the limiting block 15 in the Y direction, so that the suction cup assembly 03 has a certain rotation space. When the suction cup assembly 03 rotates to the limit position, it contacts the limiting block 15, and the push-pull cylinder 3 can no longer move, thereby limiting the rotation of the suction cup assembly 03.

[0088] In one embodiment, a protective layer may be provided on the limiting component to prevent damage from collisions when the suction cup component 03 and the limiting block 15 come into contact.

[0089] Based on any of the above embodiments, the suction cup assembly 03 includes a suction cup rotating square tube 8, and a plurality of suction cups 9 are connected to the suction cup rotating square tube 8.

[0090] The two ends of the suction cup rotating square tube 8 are connected to the bearing seats 10 corresponding to the two ends of the bracket assembly 01.

[0091] Please refer to Figure 2 , Figure 3 , Figure 5 The suction cup assembly 03 includes a suction cup rotating square tube 8 and a plurality of suction cups 9 connected to the suction cup rotating square tube 8, wherein the suction cups 9 are the main components for adsorbing the workpiece 16.

[0092] Both ends of the suction cup rotating square tube 8 are rotatably connected to the bracket assembly 01. More specifically, a bearing seat 10 is provided on the bracket assembly 01. Both ends of the suction cup rotating square tube 8 are rotatably connected to the bracket assembly 01 through the bearing seat 10, ensuring a smooth and reliable rotation effect, avoiding damage to the cylinder and suction cup rotating square tube 8 due to rotation jamming, and ensuring the service life of the components.

[0093] It should be noted that, in this embodiment, with the axial direction of the bearing seat 10 as the reference, the suction cup rotating square tube 8 and the multiple suction cups 9 connected to the suction cup rotating square tube 8 rotate counterclockwise or clockwise around the axis of the bearing seat 10.

[0094] Specifically, suction cup 9 is equipped with a vacuum generator and vacuum equipment. The vacuum equipment supplies compressed air to the vacuum generator, which generates negative pressure, causing suction cup 9 to generate negative pressure to adsorb products.

[0095] Based on any of the above embodiments, the bracket assembly 01 includes:

[0096] Crossbeam 1;

[0097] Side beam 2 is provided on both sides of cross beam 1. One end of side beam 2 is connected to the end of cross beam 1, and the other end of side beam 2 is provided with bearing seat 10.

[0098] Please refer to Figure 2 , Figure 3 , Figure 4 The bracket assembly 01 includes a crossbeam 1 and side beams 2. The two ends of the crossbeam 1 are connected to two side beams 2. The bearing seat 10 is installed on the side beams 2. The suction cup assembly 03 is connected to the bearing seat 10 through the suction cup rotating square tube 8, so that the suction cup assembly 03 can rotate when pushed or pulled.

[0099] Both the crossbeam 1 and the side beam 2 are made of high-strength plates to ensure the overall reliable operation of the support assembly 01.

[0100] In this embodiment, to ensure the reliability of the two side beams 2, a transverse support beam 6 and a vertical support beam 7 can be added to ensure that the overall bracket assembly 01 still has good stability when the suction cup assembly 03 rotates.

[0101] In this embodiment, the bracket assembly 01 is a frame structure, which is well-suited for long strip workpieces placed in narrow spaces. It is especially suitable for the handling and stacking of corner columns in automated production of box-type houses, allowing corner columns to be stacked in narrow areas, thereby saving space for corner column placement.

[0102] Based on any of the above embodiments, the mounting part 5 is connected to the top of the crossbeam 1, and the push-pull assembly 02 is connected to the bottom of the crossbeam 1.

[0103] Please refer to Figure 2 , Figure 4 The mounting part 5 is detachably connected to the crossbeam 1 to provide greater operational flexibility and facilitate disassembly and maintenance of the mounting part 5. Specifically, the mounting part 5 is a mounting plate connected to the top of the crossbeam 1, and this mounting plate can be set according to the structural adaptability of the transfer component.

[0104] The push-pull assembly 02 is connected to the bottom of the crossbeam 1 and will not interfere with the mounting part 5. The push-pull assembly 02 can be installed using the space under the crossbeam 1.

[0105] Based on any of the above embodiments, a transverse support beam 6 is also provided on the lower side of the crossbeam 1, and the end of the transverse support beam 6 is connected to the side beam 2.

[0106] A vacuum generator 11 and a filter 14 are installed on the transverse support beam 6. The vacuum generator 11 is connected to the suction cup 9 through the filter 14.

[0107] Please refer to Figure 2 A transverse support beam 6 is also provided on the lower side of the crossbeam 1. The end of the transverse support beam 6 is connected to the side beam 2 to enhance the stability and reliability of the entire bracket assembly 01.

[0108] In addition, the transverse support beam 6 can also be used to provide installation space, specifically for installing the vacuum generator 11 and the filter 14. A solenoid valve assembly 12 is installed at the bottom of the beam 1. The solenoid valve assembly 12 is opened by the control element to supply air to the vacuum generator 11. The vacuum generator generates negative pressure, and the negative pressure airflow is filtered out of impurities and moisture by the filter 14. Finally, a vacuum suction force is generated at the suction cup 9 to adsorb the product.

[0109] To detect whether the suction cup 9 has picked up the workpiece 16, a vacuum pressure switch 13 can be installed on the transverse support beam 6. The vacuum pressure switch 13 is used to detect the value generated when the suction cup 9 picks up the workpiece 16 and transmit it to the control element. The control element analyzes this value to determine whether the workpiece 16 has been reliably picked up.
