Description

[0033] Furthermore, if Figure 6 As shown, the first suction structure 100 includes a bracket 110 and multiple first cylinders 120; multiple first cylinders 120 are installed on the support frame 300, and the piston rod end of the first cylinder 120 is connected to the top surface of the bracket 110; a clamping cavity is provided inside the bracket 110, and a first threaded hole connected to the clamping cavity is provided on the bottom surface of the bracket, and a suction nozzle 130 is installed at the first threaded hole; a first air pipe 140 connected to the clamping cavity is fixedly provided on one side of the bracket 110 for connecting to an external negative pressure device; the second suction structure 200 has the same structure as the first suction structure 100; a clamping cavity is set as the gathering place of multiple suction nozzles, and then the first air pipe is used for unified external connection, which can reduce the layout of external air supply hoses, facilitate the design and layout of the overall structure, and make it more compact and beautiful as a whole; and the overall structure adopts a detachable structure, which can facilitate the production, processing or procurement of various structural components for assembly, as well as subsequent inspection and disassembly.

[0034] Furthermore, if Figure 10 As shown, the dust collecting structure 400 includes a dust collecting component 500 and an adjusting mechanism 600; the adjusting mechanism 600 is used to drive the dust collecting component 500 to move and rotate and swing; Figure 1 、 Figure 2 、 Figure 8 As shown, when the dust collection component moves to the outside of the insertion end of the support frame, it sucks and collects dust below; Figures 3 to 5 and Figure 9As shown, when the dust collection component rotates and swings to the bottom of the support frame, it can suck dust from the upper part; the dust collection component can be adjusted to two working positions, adapting to the corresponding placement position of the workpiece to meet the requirements of suction and dust removal on the upper and lower surfaces of the workpiece; and the position of the dust collection component changes accordingly with the part of the workpiece to be adsorbed and dust removed, maintaining only a single targeted suction part, effectively maintaining the overall dust collection force, and improving the cleaning quality.

[0035] Furthermore, if Figure 7 As shown, the dust collection assembly 500 includes a support cylinder 530, a blocking member 540, a first end cap 510, and a second end cap 520; the first end cap 510 and the second end cap 520 are respectively mounted on both ends of the support cylinder 530, and a second air pipe 550 is connected to the first end cap 510. The second air pipe is connected to an external vacuum equipment through a hose to maintain the required negative pressure effect, perform effective vacuuming and dust collection, and do not affect the normal rotation and swing requirements of the support cylinder;

[0036] The support tube 530 is provided with two air suction ports 531, which extend along the length of the support tube, and the line connecting the two air suction ports 531 and the axis of the support tube 530 forms a 90° angle; and when the dust collection assembly moves to the outside of the insertion end of the support frame, one of the air suction ports faces downward, and the other air suction port faces one side of the support frame; the blocking member 540 is a tube-shaped structure with two ends open, and the blocking member 540 rotates closely against the inner wall of the support tube 530 to switch and block the two air suction ports 531; when the dust collection assembly is in a horizontal state, the air suction port at the bottom is opened separately to carry out dust collection on the upper surface of the finished workpiece on the corresponding workstation;

[0037] When the dust collection component is in an upright position, the upper air intake is opened separately and driven by the adjustment mechanism, and can be used to clean the bottom surface of the finished workpiece; the effect of maintaining a single air intake open ensures effective air suction and dust removal.

[0038] Furthermore, the side wall of the blocking member 540 is provided with two strip holes 541 symmetrically arranged about the axis, and the length of the strip holes is adapted to the length of the air intake port; counterweight bars 542 are fixedly provided on both sides of the inner wall of one of the strip holes 541; the counterweight bars are used to limit the center of gravity of the blocking member to ensure that it can be maintained at the required angular position, thereby achieving the blocking or conduction of the air intake port, achieving the above-mentioned effect of maintaining a single air intake port open, and ensuring that an effective air intake and dust removal effect is provided.

[0039] Furthermore, if Figures 10 to 12As shown, the adjustment mechanism 600 includes a second cylinder 610, a push frame 620, a push rod 630, and a spring 640; the push rod 630 is slidably mounted on the side wall of the support frame 300, the push frame 620 is slidably mounted on the push rod 630, and the spring 640 is clamped and mounted between the push portion of the push frame 620 and the push rod 630; the piston rod end of the second cylinder 610 is connected to the end of the push frame 620 through a frame plate, and the dust collection component 500 is rotatably mounted between the ends of the two push rods 630 away from the spring 640; the second cylinder 610 is mounted on the support frame 300, and when the second cylinder 610 drives the push frame 620 When the push rod 630 moves toward the dust collection assembly 500, it stops after moving to a preset position. The push frame 620 compresses the spring 640 and continues to push the dust collection assembly 500 a preset distance, pushing the dust collection assembly 500 to rotate and swing to a horizontal position, so that the downward air intake port is opened. When the second cylinder 610 drives the push frame 620 to move away from the dust collection assembly 500, the push frame 620 releases the push on the dust collection assembly 500, and the dust collection assembly 500 rotates and swings downward to an upright position, so that the upward air intake port is opened. The push frame 620 and the push rod 630 continue to move, so that the dust collection assembly 500 passes under the first suction structure 100.

[0040] With the cooperation of this structure, the second cylinder can drive the pushing frame and the pushing rod to move, and after the movement of the pushing rod is blocked, it continues to push the pushing frame, so that the dust collection component can swing upward to a horizontal state, maintaining the air suction port in the downward position. When it passes above the top surface of the workpiece, it can perform effective suction and dust removal. When the second cylinder moves in the opposite direction, it can drive the pushing frame to move in the opposite direction, contacting the pushing of the dust collection component, and the dust collection component swings downward to an upright state under its own gravity.

[0041] Furthermore, the push frame 620 includes a support plate 621 and a push plate 622 fixed to the top surface of one end of the support plate 621. Two guide blocks 623 are fixed to the top surface of the support plate 621, and a guide groove 631 is correspondingly provided on the bottom surface of the push rod 630.

The guide rod 625 is slidably inserted in the third guide hole 632, and the spring 640 is sleeved on the guide rod 625 and clamped between the push plate 622 and the end of the push rod 630; the side walls of both ends of the support cylinder 530 are fixed with docking plates 532, and the end of the docking plate 532 is rotatably mounted on the side wall of the push rod 630 away from the push plate by bolts; its overall assembly structure can facilitate the processing and production of various structural components, and also facilitate the inspection, disassembly, assembly or replacement of parts; among them, when the push rod moves toward the dust collection component, when the guide bolt is stuck in the end of the second guide hole, the movement of the push rod is blocked; at this time, the push frame is continued to be pushed, and the push frame can still continue to move, thereby pushing and driving the dust collection component to swing upward; until the push frame moves to the preset stroke position, the dust collection component remains in a flat state;

[0042] When the pushing frame moves away from the dust collection component, it drives the pushing frame to move, releases the pushing of the dust collection component, and the dust collection component rotates to a vertical position; when the guide bolt moves to the end of the first guide hole, it drives the push rod to move, thereby driving the dust collection component to pass under the first suction structure to perform dust collection on the bottom surface of the clamped workpiece.

[0043] The present invention also discloses a loading and unloading device, comprising a manipulator and the aforementioned one-piece inductor production grabbing device; the end of a support frame is mounted on a movable component of the manipulator, and the manipulator drives the one-piece inductor production grabbing device to perform multi-directional movements; the manipulator drives the support frame to perform multiple movements including but not limited to vertical, front-back, left-right, rotation, and flipping, so that it can be better used in conjunction with the one-piece molding equipment to achieve corresponding movements;

[0044] More specifically, the following steps are included:

[0045] S1, the robot drives the support frame to move to the loading position, picks up the coil part through the second suction structure, and rises to the preset height;

[0046] S2, activating the adjustment mechanism to maintain the dust collection component in a horizontal position; the manipulator drives the support frame to move toward the integrated molding equipment and extends a preset distance toward the processing location; during this movement, the dust collection component passes over the previously processed workpiece A and performs dust collection on the upper surface of workpiece A;

[0047] S3, start the first suction structure, suck the workpiece A, and raise it to a preset height;

[0048] S4, the manipulator drives the support frame to continue moving forward a preset distance, so that the second suction structure moves to a preset position; the second suction structure is adjusted to lower the coil part to the processing position;

[0049] S5, the robot moves the support frame outward and moves to the unloading position;

[0050] When the dust collection component is separated from the forming processing part, the adjustment mechanism is activated to make the dust collection component swing down to the preset position and pass under the workpiece A to vacuum the lower surface of the workpiece A before unloading;

[0051] S6, adjusting the first suction structure so that the workpiece A is below the unloading position;

[0052] Afterwards, the above actions can be repeated to realize the loading and unloading of coil parts and finished workpieces, and the upper and lower surfaces of the finished workpieces can be vacuumed and dusted without the need for subsequent separate treatment; it should be pointed out that in step S5, if the vertical height of the processing part of the molding equipment is sufficient, the adjustment mechanism can be started after the first suction structure grabs the workpiece and rises to the preset height position, and the bottom of the workpiece can be processed accordingly, which further shortens the time and further prevents dust from falling to the outside.

[0053] The present invention is described through preferred embodiments. Those skilled in the art will appreciate that various modifications or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
