Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, in particular to a solenoid valve coil resistance welding device. Background Art

[0002] Resistance welding uses the resistance heat generated by an electric current passing through the contact surfaces and adjacent areas of the workpieces as a heat source, while simultaneously applying pressure to create a weld. The basic principle of resistance welding can be summarized as "resistance heating, thermal melting, and pressure consolidation." When two metal workpieces to be welded are brought into close contact, a high current (several thousand to tens of thousands of amperes) flows through the contact surfaces. Due to the minute resistance at the contact surfaces, the current generates a significant amount of heat, rapidly melting the metal in the contact area. Under sustained pressure, the molten metals penetrate and diffuse into each other, forming a strong weld upon cooling. Resistance welding is commonly used for the welding and installation of electronic components such as capacitors and resistors.

[0003] For example, a resistor assembly machine with publication number CN111805113B includes a frame, a resistor welding device, a resistor shell insertion mechanism and a first turntable, wherein the first turntable is provided with a plurality of first carriers, the first carrier is provided with a first receiving slot for receiving the shell and two second receiving slots for receiving the resistors; the resistor assembly machine also includes a resistor shaping device, the resistor shaping device includes a second turntable and a liftable first pressure head, the second turntable is provided with a plurality of second carriers, the second carrier is provided with a plurality of third receiving slots for receiving the resistors, the pins of the resistor extend into the first avoidance hole next to the third receiving slot, the first pressure head can extend into the first avoidance hole and bend the pins; the resistor welding device is used to weld the resistors in the two second receiving slots together; the resistor shell insertion mechanism is used to install the two welded resistors on the shell.

[0004] However, the above-mentioned resistor assembly machine can only bend and weld resistors in the vertical direction through fixed-shaped receiving grooves. It is difficult to perform welding and installation on workpieces that need to be welded with capacitors or resistors in irregular shapes or that need to be welded in multiple positions (such as solenoid valve coil plug terminals), and its applicability is low. It is also difficult to inspect and classify the workpieces after welding, and manual inspection is required, which is inefficient. Summary of the Invention

At this time, a pair of cutting cylinders 1203 on both sides of the top of the capacitor feeding mounting frame 1201 drive the cutting block 1204 at the bottom to move downward to cut the redundant pins of the capacitor 604.

At this time, the fifth translation mechanism 1702 drives the unloading cylinder 1703 and the second clamping claw 1705 to move to the top of the solenoid valve coil 6, and then the unloading cylinder 1703 drives the second clamping cylinder 1704 and the second clamping claw 1705 to move downward. During the movement of the second clamping cylinder 1704, the second clamping claw 1705 is driven to open until the second clamping claw 1705 is located on both sides of the solenoid valve coil 6 and stops. Then, the solenoid valve coil 6 is clamped and fixed by the second clamping claw 1705, and the above steps are repeated in reverse to transport the solenoid valve coil 6 to the top of the conveyor belt 1706 to transport the processed solenoid valve coil 6; during the transportation process, the partition 1707 can be used to separate the top of the conveyor belt 1706 into corresponding good product areas and defective product areas with different defects. During transportation, the corresponding solenoid valve coil 6 can be placed in the corresponding area to classify the processed solenoid valve coil 6 to avoid mixing.

[0047] Working principle: During welding, the solenoid valve coil 6 to be processed is manually placed on the positioning mechanism 5 facing the operating window 2 through the operating window 2. When installing, the solenoid valve coil 6 is sleeved on the outside of the limit pin 502, and the limit groove 503 on the top of the base 501 is engaged with the limit bar at the bottom of the solenoid valve coil 6 to limit the solenoid valve coil 6. During installation, the plug terminal 601 is placed facing away from the center of the turntable 4. The initial positions of a pair of first welding strips 602 are in a state of folding inwardly toward each other, and the initial positions of a pair of second welding strips 603 are in a state of bending upward 90° toward each other; then the turntable 4 is driven by the rotating mechanism to start rotating, so that the positioning mechanism 5 and the solenoid valve coil 6 on the edge of the turntable 4 pass through the height detection mechanism 7, the welding pre-pressing mechanism 8, the resistance welding mechanism 9, the welding thickness detection mechanism 10, the capacitor installation mechanism 11, the resistance testing mechanism 14, the first size detection mechanism 15, the second size detection mechanism 16 and the sorting and blanking mechanism 17 for two circles in turn.

[0048] During the rotation, the height of the solenoid valve coil 6 on the positioning mechanism 5 is detected by the height detection mechanism 7, and then the top of the first welding strip 602 of the solenoid valve coil 6 is pre-pressed by the welding pre-pressing mechanism 8; during the height detection, the positioning mechanism 5 and the solenoid valve coil 6 move with the turntable 4 to the bottom of the detection pressure block 703. At this time, the second lifting mechanism 702 drives the detection pressure block 703 to move downward until the detection pressure block 703 abuts against the top of the solenoid valve coil 6 to detect the height of the solenoid valve coil 6; after the detection is completed, the positioning mechanism 5 The solenoid valve coil 6 moves with the turntable 4 to the bottom of the welding pre-stressing mechanism 8. At this time, the pre-stressing head 805 is located directly above the first welding strip 602. During pre-stressing, the pre-stressing top block 803 is first driven upward by the third lifting mechanism 802 until it abuts against the bottom of the first welding strip 602 to support the first welding strip 602. Then, the pre-stressing head 805 is driven downward by the fourth lifting mechanism 804 to pre-stress the first welding strip 602 at the bottom of the pre-stressing head 805 to prevent it from warping during welding and affecting the welding effect.

[0049] Then the resistance welding mechanism 9 welds the to-be-welded portion of the solenoid valve coil 6. During one welding operation, the positioning mechanism 5 and the solenoid valve coil 6 move with the turntable 4 to the bottom of the resistance welding mechanism 9. At this time, the welding head 907 is located directly above the first welding strip 602. The conductive top block 904 is driven upward by the fifth lifting mechanism 903 until it contacts the bottom of the first welding strip 602. Then, the sixth lifting mechanism 905 drives the conductive frame 906 and the welding head 907 to move downward until the welding head 907 contacts the top of the first welding strip 602. When the two ends of the resistance welding device 907 are in contact with each other, the circuit between the welding head 907, the plug terminal 601 and the conductive top block 904 is connected, and high temperature is generated when the current passes through the first welding strip 602 of the plug terminal, and the first welding strip 602 is welded; during the secondary welding, the second translation mechanism 901 drives the resistance welding mounting frame 902 to move away from the turntable 4, so that the welding head 907 and the conductive top block 904 move to the upper and lower sides of the second welding strip 603 and stop, and the above steps are repeated to weld the second welding strip 603 and the pins of the capacitor 604.

[0050] After welding, the thickness of the welding position of the solenoid valve coil 6 is detected by the welding thickness detection mechanism 10. After the first welding, the positioning mechanism 5 and the solenoid valve coil 6 move to the opposite position of the welding thickness detection mechanism 10 with the rotating disc 4. At this time, the first welding strip 602 is located between the upper movable block 1004 and the lower movable block 1005. The upper movable block 1004 and the lower movable block 1005 are driven by the bidirectional cylinder 1003 to move towards the first welding strip 602 until they respectively abut the upper and lower sides of the first welding strip 602. At this time, the welding thickness of the first welding strip 602 can be detected by the detection probes 1006 on both sides.

[0051] After the first welding, the capacitor 604 is installed on the lower side of the second welding strip 603 of the solenoid valve coil 6 by the capacitor installation mechanism 11. When installing, the solenoid valve coil 6 and the positioning mechanism 5 are located directly below the limiting pressure head 1107, and the capacitor 604 is located at the bottom of the second welding strip 603. At this time, the bottom solenoid valve coil 6 is fixed by driving the limiting pressure head 1107 downward by the ninth lifting mechanism 1104. Then, the first bending push block 1106 is driven upward by the first lifting mechanism 1102. In the process of upward movement of the first bending push block 1106, the two ends of the capacitor 604 are bent upward by 90° by the profiling bending blocks 1110 on both sides until the top grooves 1111 on both sides abut the bottom of the second welding strip 603. At this time, the second bending push block 1109 is driven towards the first bending push block 1106 by the first translation mechanism 1112. The pins at both ends of the capacitor 604 are bent again by 90° away from the axis of the rotating disc 4 by the second bending push block 1109, so that the pin ends on both sides of the capacitor 604 are in a horizontal state at the top of the second welding strip 603. Then, a pair of third bending push blocks 1113 are driven towards the bending portions of the pair of second welding strips 603 by the inclined cylinders 1103, so that the bending portions of the pair of second welding strips 603 are rotated towards each other to clamp the capacitor 604 pins on the inner side. When the bending portions of the second welding strip 603 are bent inward by 45°, the third bending push blocks 1113 are driven to reset by the inclined cylinders 1103. Finally, the pressure maintaining pressure head 1108 is driven downward by the seventh lifting mechanism 1105 to press and combine the bending portions of the second welding strip 603 at the bottom, so that the second welding strip 603 is in a folded state, and the capacitor 604 pins on the inner side are clamped and fixed, realizing the installation of the capacitor 604.

[0052] In the process of installing the capacitor 604, the capacitors 604 arranged uniformly in a strip are conveyed by the stepping conveying mechanism 1202 and finally moved to the top of the cutting top block 1205. At this time, the cutting block 1204 at the bottom is driven downward by a pair of cutting cylinders 1203 at the top of the capacitor feeding installation frame 1201 to cut the excess pins of the capacitor 604. The cut pins of the capacitor 604 fall into the inside of the waste box 1206 along the waste groove for centralized treatment. At this time, the rotary cylinder 1304 drives the first clamping cylinder 1305 and the first clamping jaw 1306 to rotate toward the direction of the cut capacitor 604 until the first clamping jaw 1306 stops when it is located in the gap between the pair of cutting top blocks 1205. Then the fourth translation mechanism 1301 is driven upward by the feeding lifting mechanism 1302. When the fourth translation mechanism 1301 moves upward, the first clamping jaw 1306 moves upward until the height of the first clamping jaw 1306 is consistent with the height of the cut capacitor 604. At this time, the first clamping jaw 1306 is driven by the fourth translation mechanism 1301 to move toward the cutting top block 1205 until the first clamping jaw 1306 is located on the upper and lower sides of the cut capacitor 604. Then the first clamping jaw 1306 is driven by the first clamping cylinder 1305 to clamp and take the cut capacitor 604. After taking the material, the above steps are repeated in reverse to convey the cut capacitor 604 to the bottom of the corresponding second welding strip 603 to realize automatic taking and feeding of the capacitor.

[0053] After the welding thickness detection is completed, the positioning mechanism 5 and the solenoid valve coil 6 move to the bottom of the resistance testing mechanism 14 with the turntable 4. The detection limiting block 1403 is driven downward by the fixed cylinder 1402 to limit and fix the solenoid valve coil 6 at the bottom. Then the conductive probe 1405 is driven by the detection cylinder 1404 to move toward the direction of the plug terminal 601 until the conductive probe 1405 abuts against the end of the plug terminal 601, so that the circuit between the conductive probe 1405 and the plug terminal 601 is conducted to detect the resistance of the solenoid valve coil 6. After the detection is completed, the positioning mechanism 5 and the solenoid valve coil 6 move through the first size detection mechanism 15 and the second size detection mechanism 16 in turn with the turntable 4. The size of the solenoid valve coil 6 is detected in all directions by the horizontally arranged first camera and the vertically arranged second camera.

[0054] After detection, the positioning mechanism 5 and the electromagnetic valve coil 6 move with the rotating disc 4 to the bottom of the sorting and discharging mechanism 17, at this time the fifth translation mechanism 1702 drives the discharging cylinder 1703 and the second clamping jaw 1705 to move to the top of the electromagnetic valve coil 6, then the discharging cylinder 1703 drives the second clamping cylinder 1704 and the second clamping jaw 1705 to move downward, the second clamping cylinder 1704 drives the second clamping jaw 1705 to open during movement, and stops when the second clamping jaw 1705 is located on both sides of the electromagnetic valve coil 6, then the second clamping jaw 1705 clamps and fixes the electromagnetic valve coil 6, and the above steps are repeated in reverse to carry the electromagnetic valve coil 6 to the top of the conveying belt 1706, the processed electromagnetic valve coil 6 is conveyed, and the processed electromagnetic valve coil 6 is conveyed to the outside of the rack 1 through the discharge port 3; the top of the conveying belt 1706 can be separated into corresponding good product areas and different defective product areas by the partition plate 1707 during carrying, and the corresponding electromagnetic valve coil 6 can be placed in the corresponding area during carrying, the processed electromagnetic valve coil 6 is classified to avoid mixing.
