Detailed Implementation

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] The magnetron primary characteristic testing device of this utility model, such as Figure 1 and Figure 2 As shown, the device includes a waveguide testing module 2, which has a test slot 201 for placing a magnetron 99. The magnetron primary characteristic testing equipment of this invention also includes a robotic arm assembly 3 for transferring the magnetron 99 from the pallet conveyor line 98 to the test slot 201. The pallet conveyor line 98 is prior art; for example, refer to Chinese Invention Patent Publication No. CN109704048B, "A Pallet Conveyor Line". Figure 1 and Figure 2 As shown, the magnetron primary characteristic testing equipment of this utility model also includes a defective product collection device 4, such as... Figure 3 As shown, the defective product collection device 4 is equipped with a receiving slot 41 for receiving the defective magnetron 99 transferred from the robotic arm assembly 3, such as... Figure 1 As shown, the receiving slot 41 is located in front of the test slot 201, as... Figure 5 As shown, the bottom of the receiving tank 41 is provided with a conveyor belt 43 for moving the magnetron 99 (it should be noted that only...). Figure 5 The conveyor belt 43 is schematically shown. The receiving trough 41 specifically includes two side plates 411 at the front and back. The bottom of the receiving trough 41 is also provided with a bottom plate 412. The upper part of the conveyor belt 43 is attached to the upper side of the bottom plate 412. The bottom plate 412 is installed on the inner side of the corresponding side plate 411.

[0023] like Figure 1 and Figure 2 As shown, a carrier 981 is provided on the pallet conveyor line 98. The pallet conveyor line 98 transports the carrier 981 in the left-right direction. The magnetron 99 to be tested is placed on the carrier 981 with relative positioning. When the carrier 981 moves to the corresponding front of the test slot 201, the robot arm assembly 3 transfers the magnetron 99 from the carrier 981 to the test slot 201. Then, the waveguide detection module 2 can detect the primary characteristic parameters of the magnetron 99. If the magnetron 99 is qualified, the robot arm assembly 3 puts the magnetron 99 back onto the carrier 981, and the pallet conveyor line 98 resumes transporting the magnetron 99. If the waveguide detection module 2 detects that the magnetron 99 is unqualified, since the receiving slot 41 is located in front of the test slot 201, the robot arm assembly 3 can place the unqualified magnetron 99 into the receiving slot 41, and the robot arm assembly 3 releases. The magnetron 99 is then moved by the conveyor belt 3, which moves the defective magnetron 99 in the receiving groove 41. For example, the conveyor belt 3 moves the magnetron 99 a certain distance to the right, so that the magnetron 99 leaves the placement point of the robot arm assembly 3. Then the robot arm assembly 3 picks up the next magnetron 99 on the pallet conveyor line 98. If another defective magnetron 99 appears in a short time, the robot arm assembly 3 can continue to place the next defective magnetron 99 into the receiving groove 41. Specifically, a reflective photoelectric sensor is set at the corresponding position of the above placement point. When the robot arm assembly 3 places the defective magnetron 99 on the above placement point, the defective magnetron 99 triggers the reflective photoelectric sensor. The control system controls the conveyor belt 3 to move the magnetron 99 away from the above placement point according to the signal of the reflective photoelectric sensor. The receiving tank 41 can accommodate multiple defective magnetrons 99. Since the probability of encountering defective magnetrons 99 is low, and because the robotic arm assembly 3 can move the magnetrons 99 back and forth between the carrier 981 and the test slot 201, it avoids the need for operators to constantly monitor the magnetron primary characteristic testing equipment of this invention, significantly reducing manual operation and thus improving automation and reducing labor intensity. When a large number of defective magnetrons 99 accumulate in the receiving tank 41, the operator removes the magnetrons 99 from the receiving tank 41 and then reworks and adjusts them. Since the defective magnetrons 99 do not participate in subsequent production line processes, the positioning requirements for the defective magnetrons 99 are low. Therefore, a simple conveyor belt 3 is sufficient to remove the defective magnetrons 99 from the placement point of the robotic arm assembly 3.

[0024] Furthermore, such as Figures 3 to 5As shown, there are two conveyor belts 43. The defective product collection device 4 is equipped with a motor assembly 44, a support roller 45, and a drive roller 46. One end of the conveyor belt 43 is wound around the support roller 45, meaning the support roller 45 passes through both conveyor belts 43. The other end of the conveyor belt 43 is wound around the drive roller 46, meaning the drive roller 46 passes through both conveyor belts 43. The motor assembly 44 drives the drive roller 46 to rotate via a chain, so that when the drive roller 46 rotates, it can simultaneously drive both conveyor belts 43 to rotate. A clearance 431 is provided between the two conveyor belts 43 to avoid the antenna portion 994 of the magnetron 99. The two conveyor belts 43 are arranged front and back, and the axes of the drive roller 46 and the support roller 45 are both along the front and back direction. Specifically, the robotic arm assembly 3 places the defective magnetron 99 in the receiving groove 41, and the frame-shaped yoke of the magnetron 99 abuts against the conveyor belt 43. Figure 4 As shown, at this time, the antenna portion 994 of the magnetron 99 passes through the clearance gap 431. During the process of the conveyor belt 43 transporting the magnetron 99 to the right, the antenna portion 994 moves within the clearance gap 431, ensuring that the magnetron 99 moves smoothly on the conveyor belt 43. Figure 3 As shown, there are two bottom plates 412, arranged one in front of the other. The antenna part 994 can move to the right between the two bottom plates 412. The bottom plates 412 respectively support the conveyor belt 43.

[0025] Furthermore, such as Figure 3 As shown, one end of the receiving groove 41 is provided with a baffle 42 for blocking the magnetron 99. Specifically, the baffle 42 is installed at the right end of the receiving groove 41. When the conveyor belt 43 transports the unqualified magnetron 99 to the right, the magnetron 99 will be blocked when it reaches the baffle 42, thus preventing the magnetron 99 from falling out of the receiving groove 41.

[0026] Furthermore, such as Figure 1 Combination Figure 3 As shown, the baffle 42 is located outside the activity range of the corresponding robotic arm component 3. Specifically, the baffle 42 is located to the right of the left and right linear modules 32 of the robotic arm component 3, which is located on the right side. Therefore, it is not easy for the operator to touch the magnetron 99 when picking up the baffle 42, which is beneficial to safe production.

[0027] Furthermore, such as Figure 1As shown, the magnetron primary characteristic testing equipment of this utility model also includes a support platform 5 set in front of the pallet conveyor line 98 and a workbench 1 set in the rear of the pallet conveyor line 98. The waveguide testing module 2 is set on the workbench 1, and the defective product collection device 4 is set on the support platform 5. That is to say, the distance from the test slot 201 to the carrier 981 is less than the distance from the test slot 201 to the receiving slot 41. Since the magnetron 99 has fewer defective cases, the gripper 36 of the robot arm component 3 has fewer opportunities to move to the receiving slot 41. Most of the time, the gripper 36 only needs to move between the test slot 201 and the carrier 981, which helps to reduce the total movement distance of the gripper 36 of the robot arm component 3.

[0028] Furthermore, the robotic arm component 3 includes a front and rear linear module 31. The front and rear linear module 31 is existing technology. For example, refer to the "linear module" in Chinese Utility Model Patent Publication No. CN206368907U. The "front and rear" in the front and rear linear module 31 refers to the fact that the slide of the front and rear linear module 31 is slidably arranged in the front and rear direction. The front end of the front and rear linear module 31 is located above the support platform 5, and the rear end of the front and rear linear module 31 is located above the worktable 1. That is to say, the front and rear linear module 31 crosses the pallet conveyor line 98. Specifically, the magnetron primary characteristic testing equipment is equipped with a gantry frame. The front leg of the gantry frame is installed on the support platform 5, and the rear leg of the gantry frame is installed on the worktable 1. The front and rear linear module 31 is installed on the top of the gantry frame. The above layout is reasonable and can avoid interference between the front and rear linear module 31 and the pallet conveyor line 98.

[0029] like Figure 6 As shown, the robotic arm assembly 3 also includes a left and right linear module 32, a transverse slide 33, a lifting cylinder 34, a gripper cylinder 35, grippers 36, a test connector 37, and a lifting seat 38. The left and right linear module 32 is mounted on the slide of the front and rear linear module 31, so the front and rear linear module 31 can drive the left and right linear module 32 to move back and forth. The transverse slide 33 is mounted on the slide of the left and right linear module 32, so the left and right linear module 32 can drive the transverse slide 33 to move left and right. The lifting cylinder 34 is mounted on one end of the transverse slide 33. The lifting cylinder 34 can be a three-bar cylinder. The lifting seat 38 is equipped with the piston rod connected to the lifting cylinder 34. The gripper cylinder 35 is mounted on the lifting seat 38. The gripper cylinder 35 can be a slide cylinder. The grippers 36 are correspondingly mounted on the slide of the gripper cylinder 35. The two grippers 36 are arranged facing each other, as shown. Figure 8 As shown, the claw tips of the gripper 36 are used to insert into the bottom slot 993 of the shielding shell of the magnetron 99. Specifically, the bottom slot 993 is located between the bottom rounded corner of the shielding shell 991 and the frame-shaped yoke of the magnetron 99. Figure 6 As shown, a test connector 37 is installed on the lower side of the lifting seat 38, such as... Figure 7As shown, the lower end of the test connector 37 is provided with an electrode 371 for corresponding to the input terminal 992 of the contact magnetron 99. Figure 8 The input terminal 992 is shown schematically. Figure 8 The magnetron 99 shown is an unassembled magnetron; that is, the magnetron 99 on the pallet conveyor line 98 is an unassembled magnetron. When the gripper 36 holds the magnetron 99, the lower end of the test connector 37 extends into the shielding shell 991, so that the electrode 371 corresponds to the conductive contact input terminal 992.

[0030] like Figure 1 and Figure 2 As shown, there are two sets of robotic arm components 3. In the left-right direction, the test slot 201 is located between the front and rear linear modules 31 of the two sets of robotic arm components 3. For example, when the robotic arm component 3 located on the left places the magnetron 99 in the test slot 201, the robotic arm component 3 located on the right picks up the magnetron 99 on the carrier 981, which helps to improve work efficiency.
