[0026] The present invention is a system for automatically transporting, testing and recycling large quantities of precision electronic components that need to be tested for performance and parameter discrimination during testing, and completes the classification and recycling of qualified and defective products. Its purpose is to place the components to be tested on a carrier and put them into the equipment in large quantities at one time. After the machine is turned on, the transportation, testing, classification and recycling process can be fully automatically performed. The process includes: automatically supplying the parts to be tested, placing the parts to be tested into the testing machine for testing, automatically taking them out after the test is completed, automatically recycling qualified products, and classifying defective products according to their failure forms and placing them in defective product recovery boxes 42 with different failure forms. This embodiment proposes a fully automatic intelligent sensor testing machine, including a lifting system 2, a loading and unloading machine 3, a workbench 13, a visual system 4, a robot system 5, a detection system 6, and a defective product placement rack 7.

[0027] In one solution, the lifting system 2 includes an electro-hydraulic lift 36, an outer cover and a safety light curtain 34. The electro-hydraulic lift 36 is installed with a smooth strip 39 and an anti-slip baffle 40. The outer cover is connected to an aluminum profile outer cover 37. The equipment outlet is equipped with a safety light curtain 34. A stainless steel baffle 38 is installed at the lower end of the entrance of the lifting system 2 where it contacts the material basket transfer vehicle 1.

[0028] In one solution, the loading and unloading machine 3 includes: a loading machine and a unloading machine, the two parts are installed and fixed in parallel and against each other, and the loading machine and the unloading machine have the same structure and function. The loading machine structure is divided into: a lower transport mechanism, an upper transport mechanism, and a lifting mechanism 12. The lifting mechanism 12 is at one end of the upper transport mechanism 9 and the lower transport mechanism 8, and the upper and lower transport mechanisms are connected up and down to form a C-shaped continuous path. The horizontal transport mechanism of the workbench 13 is on the opposite side of the upper and lower transport mechanisms connected to the lifting mechanism 12.

[0029] In one solution, for the loader, the table of the lifting system 2 is lifted, so that the lower transport mechanism can transport the basket 10 containing the test pieces located at the lower layer to the lifting mechanism 12 and then descend to the lifting surface of the lower layer.

[0030] The upper transport mechanism has a pallet push rod that can push the PCB pallet 20 from the material basket 10 layer by layer onto the track on the workbench 13. The horizontal conveying mechanism of the workbench 13 has a positioning mechanism 15 to fix the PCB pallet 20. The lifting mechanism 12 is vertically lifted and lowered between the upper and lower transport mechanisms to adjust the height of the PCB pallets 20 of different layers in the material basket 10 relative to the workbench 13, so that the PCB pallets 20 of the corresponding layer to be pushed out by the pallet push rod are basically at the same height as the workbench 13. The robot system 5 is located downstream of the workbench 13 and grabs the test pieces on the workbench 13 and sends them to the detection system 6.

[0031] The lifting mechanism 12 uses a ball screw driven by a motor and a combination of two sets of linear bearings for lifting, and the lifting surface of the lifting mechanism 12 is installed with a horizontal conveying mechanism, including a motor, a sprocket mechanism, and a conveyor belt. The motor drives the sprocket mechanism, and the sprocket drives the conveyor belt for transmission. There is a return plate push rod at one end close to the robot system 5, which can push the empty PCB tray 20 back to be recycled into the material basket 10. The material frame is transported to the upper transport mechanism by the horizontal conveying mechanism of the lifting mechanism 12, and then transported to the table of the lifting platform by the upper transport mechanism. The lifting platform is in an elevated state at this time. After the lifting platform table receives the material basket 10, the material frame descends with the lifting platform table, and the material basket transfer vehicle 1 can transport the material basket 10 away.

[0032] The lower conveying mechanism 8 then conveys a material frame containing the test pieces to the lifting surface of the lifting mechanism 12 that descends to the lower layer, and the lifting mechanism 12 raises the material frame to carry out the next round of the process in which the test pieces are transported to the workbench 13 and are grasped and tested by the robot system 5.

[0033] In one solution, for the unloading machine, the table of the lifting system 2 is lifted, so that the lower transport mechanism can transport the material basket 10 with the empty PCB tray 20 located at the lower layer to the lifting mechanism 12 and then descend to the lifting surface of the lower layer. The material basket 10 is raised to a position substantially equal to the height of the workbench 13 by the lifting mechanism 12, and the return plate push rod can push back the PCB tray 20 with the qualified test piece inserted to be recovered into the material basket 10. The material frame is transported to the upper transport mechanism by the horizontal transport mechanism of the lifting mechanism 12, and then transported to the table of the lifting platform by the upper transport mechanism. The lifting platform is in an elevated state at this time. After the lifting platform table receives the material basket 10, the material frame descends with the lifting platform table, and the material basket 10 can be transported away by the material basket transfer vehicle 1.

[0034] The lower conveying mechanism 8 then conveys a material frame containing multiple layers of empty PCB trays 20 to the lifting surface of the lifting mechanism 12 that descends to the lower layer, and the lifting mechanism 12 raises the material frame to carry out the next round of qualified test piece transportation process.

[0035] In one solution, the visual system 4 includes: a set of industrial cameras 291, which are fixed above the workbench 13 of the loading machine of the loading and unloading machine 3, and the industrial cameras 29 are surrounded by LED lighting lamps 30.

[0036] In one solution, the robot system 5 includes: a six-axis robot 261, which is installed on a robot base, with an electric gripper 24 installed at the front end. The robot base is the basis of the entire equipment, and the loading and unloading machine 3 is fixed to the left mounting flange of the robot base.

[0037] In one solution, the detection system 6 can output the parameters of the detected component and provide detection environment variables of the detected component, and its detection technology belongs to the existing technology.

[0038] The defective product recovery bracket has a plurality of slideways, and a defective product recovery box 42 is located below the slideways.

[0039] The above-mentioned fully automatic intelligent sensor detection machine can achieve the following effects:

[0040] 1. The material lifting system 2 can reduce the load on the operator when directly handling the material, and avoid the safety risk of the material basket 10 injuring the operator. 2. The design of the loading and unloading machine 3 realizes one-time installation of the machine for one day's workload, reducing the frequency of replacement; it can provide continuous supply, avoiding the shutdown of the equipment; and it can operate fully automatically without supervision. 3. The application of the visual system 4 avoids the time wasted by the robot grabbing the empty space. 4. The robot system 5 can realize the automatic grabbing of the test piece from the test piece tray; it can realize the automatic placement of the test piece into the empty space of the detection system 6 and the automatic removal after the test is completed; it can realize that after the test piece is tested, it can be automatically placed in the qualified product recovery tray 17, or the defective product recovery box 42 with different failure forms according to the test results; it can avoid the untimely manual grabbing and the safety hazards of the automatic clamp of the equipment to the operator. 5. The design of the defective product recovery rack 41 enables customers to distinguish the different failure forms of defective products.

[0041] This embodiment describes a fully automated detection device for a gas sensor, preferably a detection device having an outer dimension of 20 mm in diameter x 17 mm in height.

[0042] In one embodiment, if Figure 2As shown, the PCB tray 20 for inserting the test piece adopts a double-layer PCB design and a protection circuit to meet the process requirements of the sensor. The two pins of the gas sensor can be directly inserted into the PCB tray 20. One PCB tray 20 can accommodate 50 test pieces 18. One material basket 10 can hold 17 layers of PCB trays 20 of test pieces. The PCB tray 20 is placed on the slide of the material basket 10 to facilitate the loading and unloading machine 3 to push out and return the PCB tray 20. The loading machine of the loading and unloading machine 3 can load 3 material baskets 10 at a time, that is, 2550 test pieces 18 of the sensor can be transmitted at one time.

[0043] In one solution, the loading and unloading machine 3 includes one loading machine and one unloading machine, and the structures thereof are the same. Fig.11 In the structure shown, the feeder is located on the left side, and the unloader is located on the right side. The feeder includes a lower conveying mechanism 8 located on the lower left side of the equipment, which uses a motor to drive a sprocket mechanism, and the sprocket drives a conveyor belt. The conveyor belt is a plastic chain link conveyor belt with an outer plane, 40mm wide, and is placed on both sides of the material basket 10 to make it move. Above the lower conveying mechanism 8 is an upper conveying mechanism 9, which has the same structure as the lower conveying mechanism 8. The lifting mechanism 12 is on the right side of the upper conveying mechanism 9 and the lower conveying mechanism 8, so that the upper and lower conveying mechanisms 8 are connected up and down to form an inverted C shape. It uses a mechanism composed of a ball screw and two sets of linear bearings, which is driven by a motor.

[0044] In one approach, Fig.11 In the structure shown, the workbench 13 is on the right side of the lifting mechanism 12, and its table is 150mm below the working surface of the upper conveying mechanism 9. The working area of ​​the table has an independent conveying mechanism, which is driven by two sets of pulleys by a stepper motor. In order to ensure the relative coordinate accuracy of the tested parts on the PCB and the robot grabbing, a double positioning structure is adopted. The first positioning is completed by the positioning baffle, and the conveyor belt drags the PCB to the positioning baffle and stops before the sensor responds; the second positioning is completed by two sets of lifting positioning pins, and the conical positioning pins are driven by the pneumatic slide to directly insert into the two positioning holes of the circuit board for precise positioning. Finally, the PCB tray 20 is pressed tightly with the pressing plates on the two side tracks. Below the working area, located between the two conveyor belts, is the return tray push rod, which has a spring on the push rod and will drop when it reaches the top and the end. When pushing the tray, the spring pressure is released, the push rod rises, contacts the PCB tray 20, and can push it back to the material basket 10.

[0045] In one solution, the unloading tray of the unloading machine is for blister parts. Since there is no positioning requirement, the space is ample. Each tray can hold 100 test parts 18 , each material basket 10 can hold 17 layers, and the unloading machine can also hold 3 material baskets 10 .

[0046] like Figure 4In one solution, the six-axis robot 26 of the robot system 5 uses ABB's IRB1200-5 / 0.9, and the electric gripper 24 uses IAI's RCP4-GRSML-I-28P. The electric gripper 24 is installed to the front end of the arm of the six-axis robot 26 through the gripper bracket 25. The six-axis robot 26 is installed to the robot base through its lower end flange and is fixed to the fixed surface 14 on the right side of the loading and unloading machine 3 through the flange of the left connecting bracket 22.

[0047] In order to meet the positioning accuracy requirements between the test piece and the PCB tray 20, and the positioning requirements of the test base of the robot when it is inserted into the test equipment, in one solution, the robot electric gripper 24 adopts a V-shaped arc design, which ensures the centripetal positioning of the test piece and ensures sufficient contact area to generate wrapping force without damaging the surface of the test piece.

[0048] like Figure 5 As shown in 6, the visual system 4 can solve the problem that the robot runs in the air when there is no inspection part 18 on the PCB. In one solution, the industrial camera 29 is selected: STC-MB33USB of Sentech. The industrial camera 29 is installed on the adjustable bracket 27 through the camera mounting plate 28. The base of the adjustable bracket 27 is installed on the mounting panel 33. The mounting panel 33 is fixed on the aluminum profile frame 32. Four sets of LED lighting lamps 30 are installed around the lower end through lamp brackets 31.

[0049] In one approach, if Fig. 9 The material lifting system 2 shown is composed of an electro-hydraulic lift 36, which is selected from HOULAR's MJ-A1001. The upper plane is equipped with a smooth strip 39 and an anti-slip baffle 40. There is an aluminum profile cover 37 on the outside. The equipment outlet is equipped with a safety light curtain 34, which is selected from Ryan's MCⅡ7210. A stainless steel baffle 38 is used at the lower end of the entrance where it contacts the material basket transfer vehicle 1.

[0050] In one approach, if Figure 7 and 8 As shown, there are 2 sets of defective product placement racks 7, each set can hold 6 defective product recovery boxes 42, for a total of 12 defective product recovery boxes 42. With the slide design, the robot throws defective products from the upper throwing port, and the defective products slide into the waste box through the slide, which can effectively avoid contact with human hands.

[0051] In one solution, the detection system 6 is a gas sensor detection device, there are two of them, with the same function, each with 6 detection stations, a total of 12, and the detection time of each detection station for the test piece is about 2 minutes.

[0052] In one solution, the working process of the fully automatic intelligent sensor detection machine is as follows: Preparation: The operator inserts the test piece onto the PCB tray 20 and places the PCB tray 20 onto the material basket 10. Next, the operator pushes the material basket 10 to the entrance of the lifting system 2 of the equipment through the material basket transfer vehicle 1, and enters the lower conveying mechanism 8 of the feeder through the smooth strip 39 slideway, placing 3 material baskets 10 at a time, and the conveying mechanism of the unloader is also loaded with 3 material baskets 10 with qualified product recovery trays 17.

[0053] Start working Fig.11 As shown: the operator clicks the full-automatic operation button through the control system, and the feeder and unloader work simultaneously. First, the material basket 10 is transported from the lower conveying mechanism 8 to the lifting mechanism 12, and then the device's tray pushing mechanism 11 pushes the PCB tray 20 of the test piece and the qualified product recovery tray 17 to the work area. The work area conveying mechanism places it in a fixed position and fixes it through the positioning mechanism 15. At this time, the visual system 4 identifies whether there is an empty space for the test piece 18 on the tray. If there is an empty space, the coordinate will be removed from the robot program.

[0054] The robot starts working, picks up the test piece 18 from the tray, and puts it into the inspection machine. The inspection process takes some time, and the robot will continue to work. After the inspection system 6 completes the inspection, it will send a signal to the robot through the system, and the robot will grab it. If the inspection data is qualified, it will be placed on the tray of the feeder. If it is unqualified, it will be placed in the defective recycling box marked with different failure forms 1 to 12 according to the failure form.

[0055] After the loading and unloading machine 3 completes a tray, it will be taken back to the material basket 10 from the working area again through the tray return push rod of the tray closing mechanism 19, and then the material basket 10 will be raised and pushed out of the lower tray. After completing a whole material basket 10, the material basket 10 will be sent to the upper conveying mechanism 9, and the material basket 10 of the lower conveying mechanism 8 will be sent to the lifting mechanism 12 to continue working.

[0056] The operator lowers the basket 10 of the upper conveying mechanism 9 of the loading and unloading machine 3 to the lower level through the lifting system 2, and then moves it out through the basket transfer vehicle 1. Moreover, the operator can continuously replenish the basket 10 under the condition of meeting the capacity of the loading and unloading machine 3, meeting the requirements of continuous and uninterrupted production.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
