Description

Technical Field

[0001] The utility model relates to the field of crossflow impeller accessory processing equipment, in particular to a workpiece loading device. Background Art

[0002] In automated workpiece processing or inspection equipment, workpieces need to be loaded and then transferred to a processing or inspection station using a robot, for example. In existing solutions, the robot must first descend to grab the workpiece, then ascend to carry it above the desired station, and finally descend to place it on the desired station, resulting in low efficiency.

[0003] The workpiece referred to in this case is the rubber sleeve assembly. In the crossflow impeller, the center of the motor shaft disc is provided with a rubber sleeve assembly. For details, please refer to the drawings of the crossflow impeller described in the prior patent publication number "CN107939730A". Figure 1 As shown, it includes a sleeve 100 and an annular disc 101. The inner ring of the annular disc is sleeved on one end of the central shaft. The rubber material 102 is injection-molded between the inner ring of the annular disc and the shaft body of the central shaft by an injection machine to form a rubber end face, thereby forming a complete rubber sleeve assembly. The rubber sleeve assembly is mainly used in crossflow blades. The sleeve can be connected to the output end of the fan, thereby driving the entire crossflow blade to rotate.

[0004] The sleeve in this type of rubber sleeve assembly (such as Figure 2 As shown) and the annular disc are metal parts, which can be injection molded using the rubber sleeve assembly injection vulcanization molding system and method of use described in the prior patent publication number "CN113059750B". Summary of the Invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a workpiece feeding device that can simplify the structure of the robot arm and improve the efficiency of clamping and feeding.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0007] The workpiece loading device includes a loading rail for conveying the workpiece, and a clamping robot for transferring the workpiece at the end of the loading rail to a processing station or an inspection station; it is characterized in that: the clamping robot includes a base, a cross sliding assembly arranged on the base, a crank rotatably arranged on the base, a driving motor driving the crank to rotate, and a clamping claw assembly for clamping the workpiece; the free end of the crank is rotatably connected to the upper end of the longitudinal moving part of the cross sliding assembly, and the clamping claw assembly is arranged at the lower end of the longitudinal moving part of the cross sliding assembly.

[0008] The present invention adopts the above-mentioned technical solution, which relates to a workpiece loading device, in which a loading track is used to feed the workpiece in a standardized manner, and a clamping robot is used to transfer the workpiece at the end of the loading track to a processing station or an inspection station. Compared with the existing technology, the innovation of this solution lies in the optimization of the execution structure of the clamping robot. The drive motor in this solution drives the crank to rotate, and during the rotation of the crank, it drives the cross-sliding assembly. The clamping claw assembly achieves longitudinal and lateral movement through the cross-sliding assembly to adapt to the rotation path of the crank. During this process, the clamping claw assembly can grab the workpiece at the end of the loading track and place the workpiece at the processing station or the inspection station.

[0009] Based on the above solution, a drive motor is used to drive the crank to rotate, which in turn drives the clamping jaw assembly to move in the longitudinal and transverse directions. This can simplify the structure of the robot and improve the efficiency of clamping and feeding.

[0010] In a specific embodiment, the base is provided with a transverse rail, and the cross-sliding assembly includes a transverse sliding seat mounted on the transverse rail, and a lift slide mounted longitudinally on the transverse sliding seat. The free end of the crank is rotatably connected to the upper end of the lift slide, and the clamping claw assembly is disposed at the lower end of the lift slide. In this embodiment, the transverse sliding seat of the cross-sliding assembly is capable of sliding along the transverse rail, and the lift slide is capable of moving up and down along the transverse sliding seat. Rotation of the crank drives the upper end of the lift slide in a curved circular motion, allowing the cross-sliding assembly to adaptively move laterally and vertically.

[0011] Furthermore, a guide block is provided in the transverse sliding seat, and a longitudinal slide groove is provided at the center of the guide block; the lifting slide rod is provided in the longitudinal slide groove.

[0012] Preferably, the clamping jaw assembly comprises a clamping cylinder and a clamping jaw provided on an output end of the clamping cylinder. The clamping cylinder is used to drive the clamping jaw to grasp or release the workpiece.

[0013] Preferably, a sleeve is provided on the free end of the crank, and a bearing is embedded in the sleeve. A connecting shaft is provided on the upper end of the lifting slide, and the other end of the connecting shaft is inserted into the center hole of the bearing. The provision of the bearing can reduce resistance when the upper end of the lifting slide performs curved circular motion.

[0014] Preferably, the base is provided with a pick-up sensor and a discharge sensor, each positioned along the swing path of the free end of the crank. A triggering component is provided on the free end of the crank for triggering the pick-up sensor and the discharge sensor. When the triggering component triggers the pick-up sensor or the discharge sensor, the gripper assembly grasps or releases the workpiece. This solution controls the gripper assembly's movement based on detection information from the pick-up sensor or the discharge sensor, enabling precise control of the gripper assembly to pick up and place the workpiece at the appropriate location.

[0015] Preferably, the loading track includes a track bracket, a conveyor belt cyclically arranged on the track bracket, and a conveying motor that drives the conveyor belt to circulate; the track bracket is provided with a baffle at the end of the conveyor belt, a material picking area is provided on one side of the end of the conveyor belt, and a pushing cylinder for pushing the workpiece to the material picking area is provided on the other side of the end of the conveyor belt.

[0016] Preferably, a cylinder bracket is provided on the track bracket at the end of the conveyor belt, and the pushing cylinder is installed on the cylinder bracket.

[0017] Preferably, the material taking area is provided with an in-position sensor for detecting whether a workpiece exists. After the in-position sensor detects the presence of a workpiece on the material taking area, the clamping manipulator can be allowed to clamp and load the material.

[0027] like Figure 3 and 4As shown, this embodiment relates to a workpiece loading device, comprising a loading track 1 for conveying workpieces, and a clamping robot 2 for transferring the workpiece at the end of the loading track 1 to a processing station or a detection station. The clamping robot 2 comprises a base 21, a cross-sliding assembly arranged on the base 21, a crank 22 rotatably arranged on the base 21, a driving motor 23 for driving the crank 22 to rotate, and a clamping jaw assembly 24 for clamping the workpiece. The free end of the crank 22 is rotatably connected to the upper end of the longitudinal moving part of the cross-sliding assembly, and the clamping jaw assembly 24 is arranged at the lower end of the longitudinal moving part of the cross-sliding assembly. The loading track 1 in the workpiece loading device is used to feed the workpiece in a standardized manner, and the clamping robot 2 is used to transfer the workpiece at the end of the loading track 1 to a processing station or a detection station. Compared to the existing technology, the innovation of this solution lies in the optimization of the execution structure of the clamping robot 2. In this solution, the drive motor 23 drives the crank 22 to rotate, and during the rotation of the crank 22, it drives the cross slide assembly. The clamping jaw assembly 24 is moved longitudinally and transversely through the cross slide assembly to adapt to the rotation path of the crank 22. During this process, the clamping jaw assembly 24 can grab the workpiece at the end of the loading track 1 and place the workpiece at the processing station or inspection station.

[0028] Based on the above solution, the driving motor 23 is used to drive the crank 22 to rotate, which in turn drives the clamping jaw assembly 24 to move in the longitudinal and transverse directions. This can simplify the structure of the robot and improve the efficiency of clamping and feeding.

[0029] In a specific embodiment, a transverse slide rail 25 is provided on the base 21, and the cross sliding assembly includes a transverse sliding seat 261 provided on the transverse slide rail 25, and a lifting slide bar 262 provided on the transverse slide seat 261 for longitudinal sliding. The free end of the crank 22 is rotatably connected to the upper end of the lifting slide bar 262, and the clamping claw assembly 24 is provided at the lower end of the lifting slide bar 262. In the scheme here, the transverse sliding seat 261 of the cross sliding assembly can slide along the transverse slide rail 25, and the lifting slide bar 262 can move up and down along the transverse sliding seat 261. During the rotation of the crank 22, the upper end of the lifting slide bar 262 is driven to perform a curved circular motion, and the cross sliding assembly adaptively performs transverse movement and longitudinal lifting. Furthermore, a guide block 263 is provided in the transverse sliding seat 261, and a longitudinal slide groove is provided at the center of the guide block 263. The lifting slide bar 262 is provided in the longitudinal slide groove.

[0030] like Figure 4 As shown, the clamping jaw assembly 24 includes a clamping cylinder 241 and a clamping jaw 242 provided on the output end of the clamping cylinder 241. The clamping cylinder 241 is used to drive the clamping jaw 242 to grasp or release the workpiece.

[0031] Preferably, the free end of the crank 22 is provided with a sleeve 221, which is embedded with a bearing 222. A connecting shaft 223 is provided at the upper end of the lift slide 262, the other end of which is inserted into the center hole of the bearing 222. The provision of the bearing 222 reduces resistance during the curved circular motion of the upper end of the lift slide 262.

[0032] Preferably, the base 21 is provided with a pick-up sensor 27 and a discharge sensor, each positioned along the swing path of the free end of the crank 22. A triggering component is provided on the free end of the crank 22 for triggering the pick-up sensor 27 and the discharge sensor. When the triggering component triggers the pick-up sensor 27 or the discharge sensor, the gripper assembly 24 grasps or releases the workpiece. This solution controls the movement of the gripper assembly 24 based on detection information from the pick-up sensor 27 or the discharge sensor, enabling precise control of the gripper assembly 24 to pick up and place the workpiece at the appropriate location.

[0033] like Figure 3 As shown, the loading track 1 includes a track bracket 11, a conveyor belt 12 cyclically arranged on the track bracket 11, and a conveying motor 13 that drives the conveyor belt 12 to circulate. The track bracket 11 is provided with a baffle 14 at the end of the conveyor belt 12, a material picking area 15 is provided on one side of the end of the conveyor belt 12, and a pushing cylinder 16 for pushing the workpiece to the material picking area 15 is provided on the other side of the end of the conveyor belt 12. Preferably, a cylinder bracket 17 is provided on the track bracket 11 at the end of the conveyor belt 12, and the pushing cylinder 16 is installed on the cylinder bracket 17. Preferably, an in-position sensor for detecting whether there is a workpiece is provided on the material picking area 15. After the in-position sensor detects the presence of a workpiece in the material picking area 15, it can allow the clamping robot 2 to clamp and load the material.

[0034] When the workpiece loading device is in operation, the rubber sleeve assembly is transported along the loading track 1. When the clamping robot 2 is in operation, the drive motor 23 rotates the crank 22, which in turn drives the cross-slide assembly. When the trigger component on the free end of the crank 22 triggers the pick sensor 27, the gripper assembly 24 grabs the workpiece. When the trigger component on the free end of the crank 22 triggers the drop sensor, the gripper assembly 24 drops the workpiece. This simplifies the robot structure and improves clamping and feeding efficiency.
