[0039] A feeding unit for a strip-shaped product, such as Figure 2 and Figure 3 As shown, the device includes a support 11 and a slide rail 12, a pressure plate 14, a lifting cylinder 15, a shelf 16, and a tray 17 mounted on top of it. The support 11 has a rectangular frame structure, and the top is tilted to form an inclined surface 111. A slide rail 12 is fixedly installed on each side of the inclined surface 111. The pressure plate 14 is movably connected above the slide rail 12. The pressure plate 14 is always located above the material 7. The pressure plate 14 is used to cooperate with the inclined surface to press the material 7 and push the material 7 to slide downward. The inclined surface 111 has a rectangular frame structure and has a placement part 112 for placing the material 7 inside. A tray 17 for lifting the material 7 is installed below the inclined surface 111. A lifting cylinder 15 is installed on each side of the tray 17. The lifting cylinder 15 is used to lift the material 7 through the tray 17. The lifting cylinder 15 is connected to the controller.

[0040] The controller is the central control room on the production line.

[0041] In one or more embodiments, the two sides of the pressure plate 14 are slidably connected to a slide rail 12 via a slider 13. This allows the pressure plate 14 and the inclined surface 111 to cooperate and automatically slide downwards under the action of gravity, pressing down on the material 7.

[0042] In one or more embodiments, the pressure plate 14 is a U-shaped plate, which allows the pressure plate 14 to wrap multiple materials 7 in the U-shaped groove. Since the pressure plate 14 is slidably connected to the inclined surface 111, the pressure plate 14 can move downward under the action of gravity and press the materials 7. When the bottom material 7 is removed, the pressure plate 14 will press the material 7 behind it to move downward under the action of gravity, ensuring that there is always material 7 waiting to be used at the bottom layer, which is convenient for the next process to use the material.

[0043] In one or more embodiments, a plurality of shelves 16 are placed above the inclined surface 111. The shelves 16 are used to place a plurality of materials 7, and the lower part of the materials 7 is located inside the placement part 112. Since the upper part of the materials 7 is located inside the shelves 16 and the lower part is located inside the placement part 112, and the placement direction of the shelves 16 is consistent with the sliding direction of the slide rail 12, the shelves 16 will not fall off due to gravity when placed on the inclined surface 111.

[0044] Preferably, 15 shelves 16 can be placed on each inclined surface 111. The shelves 16 are elongated structures with several through holes evenly distributed on the top for placing materials.

[0045] In one or more embodiments, the top of the pallet 17 has a stepped structure to accommodate the length of the material 7. Preferably, the lifting cylinder 15 is of model HLQ16X30S.

[0046] The working principle of the feeding unit for the strip-shaped product is as follows:

[0047] For ease of description, the column with material 7 at the bottom is called the first column, and the column with material 7 at the top is called the last column. In the previous process, the shelf 16 is filled with material 7. The worker places multiple shelves 16 with material 7 on the support 11, so that the bottom of material 7 is inside the placement part 112. Then, the 15 shelves 16 are arranged in order. Then, the pressure plate 14 is slid above the shelf 16 and presses the last column of material 7. The tray 17 is located below the first column of material. In the initial state, the controller lifts the tray 17 through the lifting cylinder 15, so that the tray 17 lifts the first column of material and is higher than the other layers of material, making it convenient for the subsequent process to remove the material of this layer.

[0049] The handling robot 2 has grippers 3 mounted on its bottom. By cooperating with the grippers 3, it transports the material 7 from the feeding unit 1 to the assembly unit 4.

[0050] The detection unit 5 is used to detect whether the materials on the assembly unit 5 are qualified and to provide feedback to the control unit.

[0051] Preferably, the control unit is the central control room on the production line, and preferably, the control unit is a PLC, model SIMATIC S7-1200.

[0052] The handling robot 2, model Z-Arm 2442, is an existing device. For ease of later description, its structure is briefly described here. The handling robot 2 includes a first arm 21, a second arm 22, a third arm 23, and a column 24. The first arm 21 can move up and down along the column 24 under the drive of the first handling motor, and is connected to the second arm 22 below through the second handling motor. The second arm 22 is connected to the third arm 23 below through the third handling motor, so that the second arm 22 can rotate relative to the first arm 21, and the third arm 23 can rotate relative to the second arm 22. The first, second, and third handling motors are all connected to the control unit.

[0053] The gripper 3 includes a fixed plate 31, a limiting plate 32, and a mini buffer cylinder 33. The fixed plate 31 is fixedly connected to the No. 3 arm 23 by bolts on the top.

The outer side of the second plate 322 is bolted to the fixing part of the mini buffer cylinder 33, and the fixing part of the mini buffer cylinder 33 is located on the outer ring of the through hole, so that when the movable part of the mini buffer cylinder 33 extends, it can press the material 7 inside the through hole.

[0055] In one or more embodiments, the fixing plate 31 is a rectangular plate.

[0056] Preferably, the model of the mini buffer cylinder 33 is PB10X10SR.

[0057] Assembly unit 4 includes base 41, cylinder 42, cylinder 43, material base plate 44, and assembly limiting plate 45. The base 41 is fixedly connected to the workbench 6 below, and the assembly limiting plate 45 is installed above it by bolts. A limiting pin 442 that is movably sleeved with the material base plate 44 is fixedly installed on one side of the assembly limiting plate 45. Several mounting holes 441 for placing materials 7 are evenly distributed on the material base plate 44. A cylinder for pushing the material base plate 44 toward the limiting pin 442 is installed on each of the two sides above the base 41. Both cylinders are signal connected to the control unit.

[0058] In one or more embodiments, the fixed end of the cylinder is bolted to the base 41, and an L-plate is installed on the movable end. The L-plate is located outside the material base plate 44. When the cylinder retracts, the L-plate presses the material base plate 44 along the limiting pin 442 toward the assembly limiting plate 45.

[0059] Preferably, the cylinders are cylinder 42 (number one) and cylinder 43 (number two), and both are model QCKL20X10.

[0060] To improve work efficiency, the number of mounting holes 441 on the material base plate 44 is the same as the number of the first layer of material in the feeding unit 1, which is 15.

[0061] The detection unit 5 includes a movable component 51 and a detection component 52 movably connected to one side thereof, and the detection unit 52 is located above the material base plate 44 and is used to detect the quality of the material 7 on the material base plate 44.

[0066] The CCD camera 521 has the model number CA-035, and the supplementary light source 523 has the model number CA-DBW8.

[0067] The working principle of a detection device for strip-shaped products is as follows:

[0068] For ease of understanding, let's take the following example: The first layer of the feeding unit 1 contains 15 pieces of material 7. The limiting plate 32 on the gripper 3 has 5 positioning holes 323, and the material base plate 44 has 15 mounting holes 441. The gripper 3 needs to perform three transports to move all the material from the first layer of the feeding unit 1 to the limiting plate 32. The time consumed for each transport of material 7 is fixed. The operating time of each electrical device can be determined in advance. Therefore, each time period is input into the control unit in advance. This operation is existing technology and will not be described in detail here. The specific process is as follows:

[0069] S1: Feeding unit 1: First, the shelf 16 carrying strip material 7 is neatly placed on the feeding unit support 11. The pressure plate 14 presses the strip material 7 through the cooperation of the slide rail 12 and the slider 13. When the switch is turned on, each unit enters the initial state. The control unit controls the lifting cylinder 15 to extend and drives the pallet 17 to move upward, lifting the 15 strip materials 7 of the first layer.

[0070] S2: Handling robot 2: After the control unit controls the lifting cylinder 15 to move, it will simultaneously control the first handling motor, the second handling motor and the third handling motor to perform corresponding actions, so that the first arm 21 of the handling robot is lifted, and the second arm 22, the third arm 23 and the quick gripper 3 are driven to the top of the 15 strip materials 7 in the first row of the feeding unit 1. In the initial state, the mini buffer cylinder 33 is in the contracted state. After the set time is reached, the first handling motor, the second handling motor and the third handling motor have completed their actions. The control unit controls the first handling motor to drive the first arm 21 to descend. Among them, 5 strip materials 7 pass through the positioning hole 323 of the limit plate 32. After the set time is reached, the control unit controls the mini buffer cylinder 33 to lift up so that the 5 strip materials 7 are clamped. Then, the first handling motor drives the first arm 21 to rise so that the 5 strip materials 7 leave the slot of the shelf 16 of the feeding unit 1. The operator can pause the operation of the control unit by switching on the switch.

[0071] S3: Assembly Unit 4: The worker manually passes the material base plate 44 through the limit pin 442 and presses it against the assembly limit plate 45. The worker uses a switch to keep the control unit working. The control unit controls the first cylinder 42 and the second cylinder 43 to retract, so that the material base plate 44 is pressed against the assembly limit plate 45 along the limit pin 442. Then, the control unit controls the first conveying motor, the second conveying motor and the third conveying motor to move, so that the first arm 21, the second arm 22 and the third arm 23 work together to transfer the 5 strip-shaped materials 7 on the gripper 3 to the top of the material base plate 44. After the set time is reached, the first arm 21 is controlled to move down to insert the 5 strip-shaped materials 7 into the mounting hole 441. After the set time is reached, the action is completed. The control unit controls the conveying robot 2 to drive the gripper 3 back to the initial position. S1 to S3 are repeated 3 times to place all 15 strip-shaped materials 7 into the mounting hole 441.

[0072] S4: Detection Unit 5: After the set time is reached, the control unit controls the module motor 515 and the detection component 52 to start working. The module motor 515 drives the moving slide 513 to move the detection component 52, that is, to move the CCD camera 521 directly above the end mounting hole 441 (when one of the photoelectric switches 512 detects the moving slide 513, it transmits a signal to the control unit, proving that the CCD camera 521 has moved directly above the end mounting hole 441). (The supplementary light source 523 remains on during device startup and is not controlled by the control unit). The CCD camera 521 begins to take pictures and transmits the data to the control unit in real time. The control unit compares the data with the sensor's output. Based on the sample data in the database, it is determined whether the strip material 7 is complete and whether the end direction is correct. If there is a problem with the material, it will be marked. After the 15 strips of material in this batch have been inspected (the photoelectric switch 512 at the other end detects the moving slide 513 and transmits the signal to the control unit, indicating that the inspection is completed), the control unit will control cylinder 42 and cylinder 43 to extend. At the same time, the display screen of the next process will indicate that the inspection is completed. The worker will remove the material base plate 44 and remove the marked defective products in the next process. Preferably, the removal of the material base plate 44 and the removal of defective products can also be done by the robot arm in the next process, which is not within the scope of protection of this application.

[0073] This invention replaces manual assembly with semi-automatic assembly. The equipment has a simple structure, low cost, and can generate high economic value. At the same time, it can save manpower and improve work efficiency.

[0074] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
