[0041] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0043] like Figure 1 As shown, a magnetron tube core initial inspection assembly process, the initial inspection assembly process of the present invention includes a tube core upright operation process and a tube core inverted operation process, wherein the tube core upright operation process includes the following steps:

[0044] S101, feeding the magnetron core 1 to be processed to the oxide layer brushing station of the upright operation line to perform oxide layer brushing treatment, wherein the object of the brushing treatment is the outer side surface of the anode cylinder 101 of the magnetron core;

[0045] S102, feeding the brushed magnetron tube core to the high-voltage testing station of the upright operation line for high-voltage electrical property testing;

[0046] The die inversion process comprises the following steps:

[0047] S301, feeding the magnetron tube core that has passed the high voltage electrical property test to the end cap placement station of the inverted operation line, and completing the loading of the end cap on the antenna side 102 of the magnetron tube core;

[0048] S302, feeding the magnetron tube core with the end cap to the end cap pressing station of the inverted operation line to complete the end cap pressing;

[0049] In the core upright operation process, the lead end of the magnetron core is located in the first direction; in the core inverted operation process, the antenna end of the magnetron core is located in the first direction; between step S102 and step S201, a magnetron core direction conversion step S20 is included.

[0050] See attached Figure 2 As shown, in this embodiment, the first direction is the up-down direction, and the lead end 103 of the magnetron core is located in the first direction, which means that the lead end of the magnetron core is located on the upper side. Specifically, the above step S101 includes the following action flow:

[0051] S1011, clamp the magnetron core and send it to the lower limit mold 2, so that the antenna side of the magnetron core is sleeved on the inner side of the lower limit mold, and the anode tube and lead end of the magnetron core are exposed from the lower limit mold; that is, the lower limit mold of this embodiment has a lower mold groove 201 for accommodating the antenna side of the magnetron core, and the feeding robot places the magnetron core in the lower limit mold, and supports and covers the antenna side of the magnetron core through the lower limit mold.

[0052] S1012, the upper limit mold 3 arranged opposite to the lower limit mold moves and is sleeved on the outside of the lead end of the magnetron core; that is, the upper limit mold of this embodiment has an upper mold groove 301 for accommodating the lead end of the magnetron core, and the upper limit mold moves from top to bottom and sleeves and covers the lead end of the magnetron core, leaving only the anode tube of the magnetron core exposed.

[0053] S1013, contact the outer side of the anode cylinder of the magnetron tube core with the wire brush 4, and make the two move towards each other to brush off the oxide layer on the outer side of the anode cylinder. As shown in the attached figure, the wire brush can be movably arranged on one side of the lower limit mold. After the magnetron tube core clamp is placed in place, the wire brush approaches and contacts the outer side of the anode cylinder, and then the two are moved relative to each other to brush off the oxide layer on the outer side of the anode cylinder. Preferably, the steel wire of the wire brush is a copper wire or a copper alloy wire, which can prevent the wire brush from scratching the anode cylinder when brushing off the oxide layer. It is easy to understand that in this embodiment, the wire brush is movably arranged in a second direction perpendicular to the first direction and can be rotatably arranged; the lower limit mold and the upper limit mold are arranged opposite to each other in the first direction, and at least one of them is a rotatable mold. For example, the above-mentioned first direction is the up and down direction, and the second direction can be the horizontal direction as shown in the attached figure. After detecting that the magnetron tube core is placed in place, the wire brush can be driven to move toward it so that the two are in contact, and then the oxide layer on the surface of the anode cylinder can be brushed off by relative rotation. In the case where the wire brush is rotatably arranged, the lower limit mold and / or the upper limit mold can also be arranged as a rotatable structure to drive the magnetron core to rotate so as to completely brush off the oxide layer on the surface.

[0054] Specifically, step S102 of this embodiment is performed according to the following process:

[0055] S1021, sending the brushed magnetron core clamp to an electrode detection and positioning mold to expose the lead end of the magnetron core;

[0056] S1022, the high voltage detection mold moves to make the high voltage test electrode contact with the cathode lead of the magnetron core;

[0057] S1023, turning on the power supply of the high-voltage test electrode, performing high-voltage electrical property detection and recording the test results.

[0058] Furthermore, the step S102 includes high-voltage instantaneous detection and high-voltage tolerance detection; in the high-voltage instantaneous detection, the high-voltage test electrode is connected to an instantaneous test high voltage, and then the electrical continuity of the cathode lead of the magnetron core is detected; in the high-voltage tolerance detection, the high-voltage test electrode is connected to a limited time test high voltage, and then the electrical continuity of the cathode lead of the magnetron core is detected.

[0059] As described above, after completing the high voltage electrical property test, the end cap on the antenna side is assembled. At this time, the antenna side is located at the bottom. In order to facilitate the operation, the magnetron core needs to be flipped. The specific magnetron core direction conversion step S20 includes the following process:

[0060] S201, after completing the high voltage electrical property test, the magnetron core is clamped and turned 180 degrees, and then placed in an intermediate movable feeding mold 5;

[0061] S202, the intermediate movable feeding mold moves to a position corresponding to the end cap assembly line or the waste recycling line according to the test result of step S102;

[0062] S203, the push cylinder 6 is actuated to push the magnetron tube core into the end cap assembly line or the waste recycling line.

[0063] See attached Figure 3 As shown, the upright operation line and the inverted operation line 7 are arranged in a staggered manner, and the intermediate movable feeding mold is movably arranged at the junction of the upright operation line and the inverted operation line. Specifically, the intermediate movable feeding mold can move in the up-down direction and in the horizontal direction. When the flipping manipulator flips the magnetron tube core after the inspection and places it in the intermediate movable feeding mold, it is judged whether the magnetron tube core is a qualified product according to the above-mentioned test results. If it is a qualified product, it runs to the position of the corresponding inverted operation line for subsequent assembly and processing; if it is an unqualified product, it runs to the position of the waste recycling line 8 for waste recycling.

[0064] In this embodiment, step S301 includes:

[0065] S3011, the push cylinder pushes the magnetron tube core in the inverted operation line to travel a distance equal to the outer diameter of the anode tube;

[0066] S3012, performing a positioning calibration action on the magnetron tube core on the end cap placement station;

[0067] S3013, clamp an end face from the end cap feeding line and place it on the antenna side of the magnetron core, so as to ensure that the end cap is placed in place.

[0068] Furthermore, the step S302 includes:

[0069] S3021, the push cylinder pushes the magnetron tube core in the inverted operation line to travel a distance of the outer diameter of the anode tube, so that a magnetron tube core with an end cap enters the end cap pressing station; the feeding structure and method of this embodiment can simplify the feeding positioning structure, ensure the consistency and action accuracy of the end cap feeding and pressing, and improve the assembly efficiency and assembly quality;

[0070] S3022, press-fitting the end cap so that the end cap is pressed and fixed on the antenna side of the magnetron core;

[0071] S3023, complete the initial inspection and assembly of the magnetron core and proceed with cutting.

[0072] After completing the above steps S101-S302, the magnetron core initial inspection and assembly process of the present invention is completed, and other subsequent magnetron processing can be performed on the qualified magnetron core.
