Description
Technical Field

In the process of processing parts, if process testing is not carried out, it is impossible to ensure that the quality of the parts meets the requirements, which will directly affect the performance of the subsequent finished products.
[0003] The existing process parameter detection is to place the processed product in the detection machine and automatically take pictures and detect it through a CCD camera. With the popularization of robots and the demand for automated processing, manual transfer of products is rarely seen in the process step of transferring products.

[0004] The three-axis linear module cooperates with the robot to complete the product transfer work. Although it replaces manual transfer, there are still certain defects. After the robot grasps the product, it needs to move in the three directions of X, Y, and Z axes to place the product on the testing table. After that, the robot must return to the original route to grasp the next product to be tested. The total operation trajectory of the robot is relatively long, and the product transfer efficiency is low. Utility Model Content

[0033] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.
[0034] like Figure 1 As shown, it is a schematic diagram of the structure of the efficient product transfer device of the utility model, which consists of three parts: a material receiving assembly, a picking assembly and a transfer assembly. The picking assembly is used to pick up the products conveyed by the vibration plate one by one, and place the products on the material receiving assembly in sequence. Finally, the transfer assembly clamps a row of products on the material receiving assembly and transfers them to the subsequent inspection station.
[0035] like Figure 2 , 3 As shown in the figure, it is a positional relationship diagram of the receiving assembly and the picking assembly. The receiving assembly includes a first bracket 1, a linear slide 2, a receiving plate 3, an inner slot 4 and an outer slot 5. The first bracket 1 is welded from aluminum profiles and mainly plays a supporting role. The linear slide 2 is fixed on the top of the first bracket 1, and the receiving plate 3 is fixed on the sliding part of the linear slide 2. The linear slide 2 drives the receiving plate 3 to move on the first bracket 1, and then successively receives the products transferred thereto by the picking assembly.
[0036] like Figure 6 The figure shows a schematic diagram of the structure of the receiving plate 3, wherein the inner card slot 4 is opened at the top of the receiving plate 3, and the outer card slots 5 are opened at both sides of the inner card slot 4 and are arranged opposite to each other. A plurality of groups of outer card slots 5 are arranged at intervals on the top of the receiving plate 3 so as to receive more products at a time and improve the efficiency of single-time transfer of products.
[0037] The picking component clamps the product and places it on the inner slot 4 of the receiving plate 3. The inner slot 4 is used to avoid the product, and the outer slot 5 matches the shape of the product and is used to limit the product placed therein, so that the subsequent transfer component can accurately clamp the product on the receiving plate 3.
[0038] The picking assembly is arranged on one side of the material receiving assembly, and is used to pick up the products conveyed by the vibrating plate one by one, and place the products on the material receiving assembly in sequence. The picking assembly includes a second bracket 6, a vertical plate 7, a picking driving wheel 8, a picking driven wheel 9, a picking conveyor belt 10, a first connecting plate 11, a second connecting plate 12, a picking plate 13, an angle plate 14 and a picking clamp 15. The second bracket 6 is fixed on the top of the first bracket 1, and the vertical plate 7 is vertically fixed on the top of the second bracket 6. The picking driving wheel 8 and the picking driven wheel 9 are rotatably installed on the same side of the vertical plate 7, and the picking driving wheel 8 and the picking driven wheel 9 are wound with a picking conveyor belt 10. A rotating motor is installed on the other side of the vertical plate 7 to drive the picking driving wheel 8 to rotate, and the torque is transmitted to the picking driven wheel 9 through the picking conveyor belt 10, driving the picking driven wheel 9 to rotate synchronously.
[0039] The first connecting plate 11 is fixed to the side of the picking driving wheel 8 away from the vertical plate 7. When the picking driving wheel 8 rotates, the first connecting plate 11 is driven to rotate synchronously. The second connecting plate 12 is fixed to the side of the picking driven wheel 9 away from the vertical plate 7. When the picking driven wheel 9 rotates, the second connecting plate 12 is driven to rotate synchronously. One side of the picking plate 13 is rotationally connected to the side of the first connecting plate 11 away from the picking driving wheel 8, and the other side of the picking plate 13 is rotationally connected to the side of the second connecting plate 12 away from the picking driven wheel 9. When the motor drives the picking driving wheel 8 to rotate, it drives the picking plate 13 to swing, and then clamps the product conveyed by the vibrating plate and places it in the card slot of the receiving plate 3.
[0040] The angle plate 14 is fixed to the side of the picking plate 13 away from the picking driving wheel 8, and the picking clamping claw 15 is fixed to the bottom of the angle plate 14 for clamping the product fed and conveyed by the vibration plate.
[0041] Since the movement trajectory of the picking plate 13 is swinging, compared with the robot gripping the product, the swinging trajectory has a shorter path and a higher picking efficiency. If the product is picked up by the robot and placed on the receiving plate 3, the running trajectory of the robot is completed in 6 steps (i.e., the robot descends to grip the product, the robot rises and resets, the robot moves to the top of the receiving plate 3, the robot descends to place the product, the robot rises and resets, and the robot retreats to the original position). Therefore, the running trajectory of the picking plate 13 is designed to swing in an arc, with the starting position being the gripping position of the product and the ending position being the placement position of the product, eliminating the transfer transition in the middle, thereby improving the efficiency of product gripping.
[0042] The picking component grabs the product conveyed by the vibrating plate and places it in a product slot on the receiving plate 3. During this period, when the picking component grabs another product, the linear slide 2 drives the receiving plate 3 to move forward by the distance of a product slot to receive another product transferred thereto by the grabbing claw 15. In this way, a row of products will be received on the receiving plate 3, and the number of products depends on the number of product slots on the receiving plate 3. Finally, the transfer component grabs a row of products on the receiving plate 3 and uniformly grabs them to the subsequent inspection station. Compared with the grabbing of a single product, the transfer efficiency of the product is significantly improved.
[0043] The transfer assembly is arranged on the top of the first bracket 1, and is used to clamp a row of products on the receiving assembly and transfer them to the subsequent inspection station. Figure 4 , 5 As shown, the transfer assembly includes a transfer frame 16, a transfer motor 17, a coupling, a transfer plate 26, a transfer driving wheel 27, a transfer driven wheel 28, a transfer shaft 29, a locking block 30, a through hole 31, a locking groove 32, a locking hole 33, a fixing plate 34 and a transfer clamp 35. The transfer frame 16 is fixed on the top of the first bracket 1, and the motor fixing plate and the shaft fixing plate are respectively fixed on the top of the transfer frame 16, and a gap is left between the motor fixing plate and the shaft fixing plate to facilitate the installation of the coupling.
[0044] The housing of the transfer motor 17 is fixed on the motor fixing plate, and the output end of the transfer motor 17 is connected to one side of the coupling. A bearing seat is fixed on the shaft fixing plate, and the drive shaft passes through the bearing seat and is connected to the other side of the coupling.
[0045] The torque of the transfer motor 17 is transmitted to the drive shaft through the coupling to drive the drive shaft to rotate, thereby completing the transfer of the product. The coupling can compensate for the relative displacement between the motor output end and the drive shaft, and also has a certain buffering and shock absorbing effect to increase the service life of the equipment.
[0046] The coupling includes two coupling claws and an elastic body, the output end of the transfer motor 17 is connected to one of the coupling claws, one end of the drive shaft is connected to the other coupling claw, and the two coupling claws are plugged together to transmit torque. The elastic body is inserted between the two coupling claws to reduce the vibration between the two coupling claws and improve the stability of torque transmission.
[0047] like Figure 7 , which is a schematic diagram of the structure of the coupling claw, the coupling claw includes a coupling block 18, an outer plug-in block 19 and an outer plug-in arc 20. The coupling block 18 is cylindrical, the outer plug-in block 19 is integrally arranged on one side of the coupling block 18, the outer plug-in arc 20 is arranged on both sides of the outer plug-in block 19, the outer plug-in arc 20 cooperates with the inner plug-in arc 23 of the elastic body, and the torque is transmitted through the outer plug-in block 19.
[0048] like Figure 8 ,9 As shown, it is a schematic diagram of the structure of the elastomer. The elastomer is generally composed of engineering plastics or rubber. Since the elastomer has the functions of buffering and vibration reduction, it can reduce the vibration between the two coupling claws, improve the stability of torque transmission, and increase the service life of the coupling.
[0049] The elastic body includes a torque plate 21, an inner plug-in block 22, an inner plug-in arc 23, a first stopper 24 and a second stopper 25. The torque plate 21 is in a thin cylindrical shape, the inner plug-in block 22 is integrally arranged on the outer circumference of the torque plate 21, the inner plug-in arc 23 is arranged on both sides of the inner plug-in block 22, and the inner plug-in arc 23 and the outer plug-in arc 20 are matched, as shown in FIG. Fig.10 As shown, the connection between the two coupling claws is achieved through an elastic body.
[0050] The first stop block 24 is integrally connected to one side of the inner plug-in block 22, and the second stop block 25 is integrally connected to the other side of the inner plug-in block 22. During actual assembly, the first stop block 24 and the second stop block 25 respectively abut against the inner side of the coupling block 18. When transmitting torque, excessive friction between the elastomer and the coupling claw can be avoided, and excessive wear of the elastomer can be avoided to reduce the service life of the coupling.
[0051] The transfer plate 26 is connected to the end of the drive shaft away from the coupling through a flat key. When the transfer motor 17 drives the drive shaft to rotate, the transfer plate 26 will be driven to rotate synchronously. The transfer shaft 29 is installed on the side of the transfer plate 26 away from the drive shaft through a bearing seat. The transfer driving wheel 27 is sleeved on the drive shaft and fixed to the bearing seat on the transfer frame 16. When the transfer motor 17 drives the drive shaft to rotate, the transfer driving wheel 27 is fixed and does not rotate with the rotation of the drive shaft.
[0052] The transfer driven wheel 28 is sleeved on the transfer shaft 29 through a flat key, and a transfer conveyor belt is wound around the transfer driving wheel 27 and the transfer driven wheel 28. When the driving shaft drives the transfer plate 26 to rotate, since the transfer driving wheel 27 is stationary, it can ensure that the transfer clamping claw 35 is always in a vertical state, that is, facing the first bracket 1, which is convenient for taking and placing products (the transfer conveyor belt is not shown in the figure).
[0053] like Fig.11 As shown, the through hole 31 and the locking groove 32 horizontally penetrate the locking block 30 and are connected to each other, and the locking hole 33 vertically penetrates the locking block 30 and the locking groove 32. The transfer shaft 29 is inserted into the through hole 31, and the locking nut is locked in the locking hole 33. During this period, the locking groove 32 gradually shrinks inward, thereby fixing the locking block 30 on the transfer shaft 29.
[0054] The fixed plate 34 is fixed to the bottom of the locking block 30, and there are multiple groups of transfer clamps 35, which are fixed at intervals on the bottom of the fixed plate 34 and are used to clamp a row of products on the receiving assembly and transfer them to subsequent inspection stations. Compared with the clamping of a single product, the transfer efficiency of the product is significantly improved.
[0055] The working principle of the high-efficiency transfer device of the utility model is as follows:
[0056] The picking component grabs the product conveyed by the vibrating plate and places it in a product slot on the receiving plate 3. During this period, when the picking component grabs another product, the linear slide 2 drives the receiving plate 3 to move forward by a product slot to receive another product transferred thereto by the grabbing jaws 15. In this way, a row of products will be received on the receiving plate 3; when the transfer motor 17 is started, the transfer plate 26 rotates close to the receiving plate 3, and the transfer jaws 35 grab a row of products on the receiving component and transfer them to the subsequent inspection station. Compared with the grabbing of a single product, the transfer efficiency of the product is significantly improved.
[0057] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
