Description

Technical Field

[0001] This utility model relates to the field of hot pressing technology, and in particular to a hot pressing feeding and picking device. Background Technology

[0002] In the automotive sheet metal thermoforming industry, it is necessary to load hot-pressed workpieces. Existing patents, such as Chinese patent application number 201820749260.2, disclose an automatic loading and unloading hot-pressing device, including a worktable, a robot, and a hot press. The worktable is located on one side of the hot-pressing operating table of the hot press, and is equipped with a loading platform and a unloading platform. The loading platform is equipped with an upper film positioning platform, a lower film positioning platform, and a steel plate positioning platform. The robot is fixedly mounted on the worktable and rotates around its fixed position. The hot-pressing operating surface of the hot press and the worktable are within the robot's rotational range. The robot's extended end is equipped with several clamps, which rotate along the axis of the extended end. A suction cup is located at the bottom of the clamp, connected to a vacuum pump via a suction pipe. The suction cup is a high-temperature resistant suction cup. This patent document describes a method of picking up workpieces using suction cups on a fixture. However, the suction cups offer poor stability in picking up workpieces and lack adjustable angles, making it difficult to handle different workpieces and resulting in poor versatility. Therefore, the shortcomings are quite obvious, and a solution is urgently needed. Utility Model Content

[0018] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0019] like Figures 1 to 4 As shown, the present invention provides a hot-press feeding and picking device, which includes two sets of feeding and picking mechanisms 1 arranged opposite to each other. Each feeding and picking mechanism 1 includes a shaft 2, a connecting arm 3 mounted on one end of the shaft 2, and a plurality of feeding and picking components 4 mounted on the shaft 2. The plurality of feeding and picking components 4 are distributed along the axial direction of the shaft 2. Each feeding and picking component 4 includes a collar 5 slidably fitted outside the shaft 2 and a first lock detachably connected to the collar 5 for locking the collar 5 onto the shaft 2. The fastener 6, the telescopic adjusting arm 7 slidably connected to the collar 5, the second locking fastener 8 detachably connected to the collar 5 and used to lock the telescopic adjusting arm 7 onto the collar 5, the connector 9 installed at the inner end of the telescopic adjusting arm 7, the universal ball 10 rotatably connected to the connector 9, the third locking fastener 11 detachably connected to the connector 9 and used to lock the universal ball 10 onto the connector 9, the mounting base 12 fixedly connected to the universal ball 10, and the clamp 13 installed on the mounting base 12.

[0020] In practical applications, this hot-pressing loading and picking device is installed at the execution end of the robot arm. Depending on the user's actual needs, the two sets of loading and picking mechanisms 1 can each pick up one or more hot-pressed workpieces to achieve simultaneous picking of multiple hot-pressed workpieces, or they can coordinate to pick up one or more hot-pressed workpieces. This embodiment uses the coordinated picking of two sets of loading and picking mechanisms 1 to illustrate the process. When the hot-pressed workpiece is located at the two sets of loading and picking mechanisms 1, at least one loading and picking component 4 in each set of loading and picking mechanisms 1 clamps a portion of the hot-pressed workpiece to achieve the gripping of the workpiece. Then, the robot arm controls the hot-pressing loading and picking device to move along with the hot-pressed workpiece to achieve loading of the hot-pressed workpiece. Depending on the specifications, size, and / or shape of the hot-pressed workpiece to be fed, loosen the first locking fastener 6 to allow the collar 5 to slide along the shaft 2, thereby adjusting the position of the feeding pickup assembly 4 on the shaft 2. This allows adjustment of the spacing between two adjacent feeding pickup assemblies 4. After adjustment, tighten the first locking fastener 6 to lock the collar 5 onto the shaft 2. Loosen the second locking fastener 8 to allow adjustment of the relative position between the telescopic adjusting arm 7 and the collar 5, thereby adjusting the effective extension of the telescopic adjusting arm 7 and thus adjusting the relative position. The relative positions of the clamps 13 on the two adjacent feeding and picking components 4 are such that the clamps 13 correspond to the clamping positions of the hot-pressed workpieces. After adjustment, tighten the second locking fastener 8 to lock the telescopic adjusting arm 7 onto the collar 5, and loosen the third locking fastener 11 to allow the universal ball 10 to rotate relative to the connector 9. The rotating universal ball 10 drives the mounting base 12 to rotate along with the clamps 13, thereby adjusting the clamping angle of the clamps 13. After adjustment, tighten the third locking fastener 11 to lock the universal ball 10 onto the connector 9. This utility model has a simple structure and low cost. The position and angle of the clamps 13 can be adjusted according to different hot-pressed workpieces, providing good flexibility and enabling clamping and feeding of different hot-pressed workpieces. It has good versatility, strong adaptability, and is convenient and efficient to adjust. In addition, the position and angle of each clamp 13 on different groups or the same group of feeding and picking mechanisms 1 can be adjusted independently according to actual conditions.

[0021] In this embodiment, the clamping device 13 includes a cylinder 14, a fixed base 15, an L-shaped fixed gripper 16, a movable gripper 17, and a connecting rod 18. The top of the cylinder body of the cylinder 14 is mounted on the mounting base 12, the fixed base 15 is mounted on the bottom of the cylinder body of the cylinder 14, the L-shaped fixed gripper 16 is mounted on the fixed base 15, a rotating cavity is provided at the corner of the L-shaped fixed gripper 16, a rotating block 19 is provided on one side of the hinge end of the movable gripper 17, the rotating block 19 extends into the rotating cavity and is rotatably connected to the inner wall of the rotating cavity, the two ends of the connecting rod 18 are respectively hinged to the piston rod of the cylinder 14 and the hinge end of the movable gripper 17, and the clamping end of the movable gripper 17 can be opened or closed relative to the clamping end of the L-shaped fixed gripper 16.

[0022] Initially, the clamping end of the movable jaw 17 and the clamping end of the L-shaped fixed jaw 16 are in the open state. At this time, the piston rod of the cylinder 14 is in the retracted state, and the hot-pressed workpiece is located between the clamping end of the movable jaw 17 and the clamping end of the L-shaped fixed jaw 16. Then, the piston rod of the cylinder 14 extends and drives the movable jaw 17 to rotate via the connecting rod 18. The clamping end of the rotating movable jaw 17 gradually approaches the clamping end of the L-shaped fixed jaw 16 until the clamping end of the movable jaw 17 engages with the clamping end of the L-shaped fixed jaw 16 to clamp the hot-pressed workpiece. Conversely, the piston rod of the cylinder 14 retracts, and the clamping end of the movable jaw 17 opens relative to the clamping end of the L-shaped fixed jaw 16 to release the hot-pressed workpiece.

[0023] In this embodiment, the fixed base 15 is provided with a movable cavity, into which the piston rod of the cylinder 14 extends. The hinge ends of the connecting rod 18, the rotating block 19, and the movable gripper 17 are all located within the movable cavity. This structural design allows the fixed base 15 to shield and protect the connecting rod 18 and the movable gripper 17, resulting in an aesthetically pleasing appearance, reduced malfunctions, and a compact structure for the fixed base 15, connecting rod 18, and movable gripper 17.

[0024] In this embodiment, the feeding and picking mechanism 1 further includes a quick-release sleeve 20 fitted over the connecting arm 3 and a locking assembly 21 disposed on the quick-release sleeve 20 and used to lock the quick-release sleeve 20 and the connecting arm 3 together. In practical applications, the quick-release sleeve 20 is installed on the actuator end of the robot arm. When it is necessary to adjust the position and / or angle of the gripper 13 on the feeding and picking mechanism 1, simply operate the locking assembly 21 to detach the connecting arm 3 from the quick-release sleeve 20, thereby facilitating the adjustment of the position and angle of the gripper 13.

[0025] In this embodiment, the locking assembly 21 includes a base 22, a rotating pressure block 23, a rotating shaft 24, and abutting bolt 25. The base 22 is fixedly connected to one side of the quick-release sleeve 20. A cavity 26 is recessed on the top surface of the base 22. The rotating pressure block 23 is rotatably disposed in the cavity 26. The quick-release sleeve 20 has a pressure hole 27, which is correspondingly disposed with the cavity 26. The rotating shaft 24 is installed on the two opposing inner walls at one end of the cavity 26. A protrusion 28 is protruding from the bottom surface of the middle part of the rotating pressure block 23. The protrusion 28 is rotatably sleeved outside the rotating shaft 24. The abutting bolt 25 is threadedly connected to the bottom surface of the base 22. The screw of the abutting bolt 25 extends into the other end of the cavity 26 and is used to abut against the bottom surface of the outer end of the rotating pressure block 23. The inner end of the rotating pressure block 23 extends into the pressure hole 27. The inner end of the rotating pressure block 23 is used to press the connecting arm 3 inside the quick-release sleeve 20.

[0026] In practical applications, when the connecting arm 3 is locked together with the quick-release sleeve 20, the screw end of the abutment bolt 25 abuts against the outer bottom surface of the rotating pressure block 23, causing the inner end of the rotating pressure block 23 to press against the connecting arm 3, thereby locking the connecting arm 3 inside the quick-release sleeve 20. When it is necessary to disassemble the connecting arm 3 and the quick-release sleeve 20, loosen the abutment bolt 25, causing the abutment bolt 25 to loosen the outer end of the rotating pressure block 23. The rotating pressure block 23 can then rotate relative to the base 22 around the rotating shaft 24, thereby causing the inner end of the rotating pressure block 23 to loosen the connecting arm 3. The connecting arm 3 can then be pulled out from the quick-release sleeve 20, thus achieving quick disassembly of the connecting arm 3 and the quick-release sleeve 20.

[0027] In this embodiment, the connecting arm 3 is slidably sleeved on the outside of the shaft 2 via the sliding sleeve 29. The sliding sleeve 29 is fixedly connected to the connecting arm 3. The sliding sleeve 29 is detachably connected to a fourth locking fastener 30, which is used to lock the sliding sleeve 29 onto the shaft 2. In practical applications, when it is necessary to adjust the relative position of the connecting arm 3 and the shaft 2 to adjust the total length of the connecting arm 3 and the shaft 2 (effective length), the fourth locking fastener 30 is loosened, allowing the sliding sleeve 29, along with the connecting arm 3, to slide relative to the shaft 2 to adjust the relative position of the connecting arm 3 and the shaft 2 (adjusting the overlap length of the connecting arm 3 and the shaft 2). After adjustment, the fourth locking fastener 30 is tightened to lock the sliding sleeve 29 onto the shaft 2.

[0028] Specifically, screws can be used for the first locking component 6, the second locking component 8, the third locking component 11, and the fourth locking component 30.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
