DETAILED DESCRIPTION

[0037] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0038] like Figure 1-8 As shown, a method for preparing a hot-pressed integrally formed T-core inductor comprises the following steps:

[0039] S1. Press the magnetic powder into a base by a cold press, inspect the appearance of the base, and select qualified products;

[0040] S2, winding copper wire on the base made and selected in step S1 by a fully automatic winding machine, and then hot pressing the base and the copper wire by a hot pressing automatic wire connecting machine to obtain a semi-finished product;

[0041] S3, performing surface treatment on the semi-finished product so that the copper wire is in a completely covered state, and then stripping and polishing the semi-finished product by means of a paint stripping device 1 so that the uppermost part of the copper wire on the base is exposed;

[0042] S4, electroplating the semi-finished product after paint stripping, so that the exposed part of the copper wire can form an electrode to obtain a finished product;

[0043] S5. Perform appearance inspection and performance test on the finished products, remove unqualified finished products, and pack qualified finished products. Finished;

[0044] The paint stripping device 1 in step S3 includes a cabinet 11 and a feeding mechanism 12, a receiving mechanism 13 and a paint stripping mechanism 14 arranged on the inner side of the cabinet 11. A linear slide 111 is provided on the platform in the cabinet 11, and a tray 112 is provided on the linear slide 111. The linear slide 111 drives the tray 112 to reciprocate between the feeding mechanism 12, the receiving mechanism 13 and the paint stripping mechanism 14; the feeding mechanism 12 is used to transport the workpiece 2 to be stripped of paint to the tray 112, the paint stripping mechanism 14 is used to strip the paint on the workpiece 2, and the receiving mechanism 13 is used to recover the workpiece 2 after the paint is stripped.

[0045] See also Figure 1 and Figure 2,, there are two paint stripping stations in the cabinet 11, each of which corresponds to a feeding mechanism 12, a receiving mechanism 13, a paint stripping mechanism 14 and a tray 112. The feeding mechanism 12, the receiving mechanism 13 and the paint stripping mechanism 14 in one paint stripping station are arranged from left to right, and the feeding mechanism 12, the receiving mechanism 13 and the paint stripping mechanism 14 in another paint stripping station are arranged from right to left. Both trays 112 are driven by a linear slide 111. Specifically, in the initial state, the tray 112 of one paint stripping station is located below the feeding mechanism 12 and waits for the feeding mechanism 12 to place the workpiece 2 to be stripped on the tray 112, and the tray 112 of the other paint stripping station is located below the paint stripping mechanism 14 and waits for the paint stripping mechanism 14 to strip the workpiece 2 on the tray 112 (because it is in the initial state at this time, there is no workpiece 2 to be stripped on the tray 112, and the paint stripping mechanism 14 is in a standby state). When the feed mechanism 12 on a paint stripping station has finished placing the workpiece 2 on the corresponding tray 112, the linear slide 111 drives the tray 112 to move toward the paint stripping mechanism 14, and the paint stripping mechanism 14 on a paint stripping station strips the workpiece 2 on the tray 112. At the same time, the tray 112 on another paint stripping station moves to the bottom of the corresponding feed mechanism 12 and places the workpiece 2. When the workpiece 2 on the tray 112 of a paint stripping station has finished stripping the paint, the tray 112 of another paint stripping station has finished placing the workpiece 2. At this time, the linear slide 111 moves in the opposite direction again, and the trays 112 of the two paint stripping stations are moved to the bottom of the corresponding receiving mechanism 13. In this way, the receiving mechanism 13 of one paint stripping station can take out the workpiece 2 on the corresponding tray 112, so that the tray 112 remains in an empty tray state again, and the receiving mechanism 13 of the other paint stripping station is in a standby state. Finally, the linear slide 111 continues to move, so that the two pallets 112 are reset to the initial state. At this time, the pallet 112 of one paint stripping station can perform feeding operations, and the pallet 112 of the other paint stripping station can perform paint stripping operations. In this way, the two pallets 112 are synchronously driven by the linear slide 111, so that the two pallets 112 can alternately perform feeding and paint stripping actions, which effectively improves the overall smoothness and maximizes the paint stripping efficiency, which is conducive to improving the overall preparation efficiency.

[0046] See also Figure 3-5The feeding mechanism 12 includes a hopper 121 and a pushing cylinder 122. The hopper 121 is L-shaped and fixed on the cabinet 11. A plurality of storage channels 1211 are provided in the vertical end of the hopper 121. The workpieces 2 can be stacked in the storage channel 1211 along the vertical direction. A plurality of discharge channels 1212 are provided in the horizontal end of the hopper 121. A discharge port 1213 is provided at the bottom of the horizontal end of the hopper 121. One end of the plurality of discharge channels 1212 is respectively and one-to-one connected to the lower end of the plurality of storage channels 1211. The other end of 1212 is connected to the discharge port 1213; a cavity 1214 is also provided on the inner side of the hopper 121, and the cavity 1214 and the discharge port 1213 are respectively located on both sides of the storage channel 1211. A connecting plate 1215 and a plurality of pushing rods 1216 are provided in the cavity 1214. The plurality of pushing rods 1216 are connected to one side of the connecting plate 1215, and the pushing rod of the pushing cylinder 122 is connected to the other side of the connecting plate 1215. The pushing cylinder 122 is used to drive the pushing rod 1216 to move toward the discharge channel 1212. The top of the storage channel 1211 is connected to the top of the cabinet 11 and is in a flush state. The workpiece 2 to be stripped of paint can be directly input into the storage channel 1211 through a vibrating loading plate. The side walls of the workpiece 2 fit into the inner wall of the storage channel 1211 to ensure that the workpiece 2 will not move in the process of being input into the storage channel 1211, so that several workpieces 2 can be stacked in sequence in the storage channel 1211.

[0047] When the empty tray 112 moves to the bottom of the hopper 121, the pushing cylinder 122 performs a pushing operation, that is, the pushing cylinder 122 pushes the pushing rod 1216 to complete a reciprocating motion. Specifically, when the push rod of the pushing cylinder 122 extends and pushes the pushing rod 1216 to move toward the discharge channel 1212, the pushing rod 1216 will push the workpiece 2 located at the bottom from the storage channel 1211 into the discharge channel 1212. When the pushing rod 1216 pushes the workpiece 2 to continue to move in the discharge channel 1212 and falls into the discharge port 1213, the workpiece 2 will fall onto the tray 112 through the discharge port 1213, and then the pushing rod of the pushing cylinder 122 retracts. During this process, other workpieces 2 in the storage channel 1211 will not move downward due to the limiting action of the pushing rod 1216 and the pushing rod of the pushing cylinder 122. Since a plurality of storage channels 1211 and a plurality of discharge channels 1212 are provided in the hopper 121, and the width of the hopper 121 is less than or equal to the width of the pallet 112, after the pushing cylinder 122 completes a pushing operation, a row of workpieces 2 can be arranged on the pallet 112, and then the linear slide 111 drives the pallet 112 to move a shorter distance, and then the pushing cylinder 122 performs another pushing operation. By repeating the above two steps, a plurality of rows of workpieces 2 can be arranged on the pallet 112. By orderly arrangement, the single arrangement quantity of workpieces 2 on the pallet 112 is increased, thereby improving the operating efficiency.

[0048] See also Figure 2 and Figure 8 The paint stripping mechanism 14 includes a bracket 141, a laser paint stripping head 142 and an illumination light source 143 arranged on the bracket 141, the laser paint stripping head 142 is located below the illumination light source 143, the laser paint stripping head 142 is used to strip paint from the workpiece 2, the illumination light source 143 is used to illuminate the workpiece 2, and an air suction hole is arranged on the outer edge ring of the bottom of the illumination light source 143, and the air suction hole is used to absorb the smoke generated by the laser paint stripping head 142 when stripping paint, so as to facilitate the operator to monitor the paint stripping status.

[0049] See also Figure 2 , Figure 6 and Figure 7 The receiving mechanism 13 includes a receiving cylinder 131, a vertical plate 132, a scraper 133 and a receiving bin 135. The receiving cylinder 131 is fixed to the inner wall of the cabinet 11. The vertical plate 132 extends in the vertical direction. A connecting rod 134 is provided at the upper end of the vertical plate 132. One end of the connecting rod 134 is connected to the vertical plate 132. The other end of the connecting rod 134 is connected to the push rod of the receiving cylinder 131. The scraper 133 is in an arc shape and is arranged at the lower end of the vertical plate 132. The bottom of the scraper 133 can be fitted with the top of the tray 112; the moving direction of the tray 112 is perpendicular to the telescopic direction of the receiving cylinder 131, and a receiving bin 135 with an open top is provided on the outside of the linear slide 111. The receiving bin 135 is located at the end of the moving direction of the scraper 133. A guide plate 1351 is provided on the top of the receiving bin 135. The guide plate 1351 is inclined and is used to guide the workpiece 2 to slide from the tray 112 into the receiving bin 135. The radial cross section of the material receiving bin 135 is square, a partition 1352 is provided in the material receiving bin 135, the outer edge of the partition 1352 is in contact with the inner wall of the material receiving bin 135, the partition 1352 is inclined and a threaded sleeve 1353 is provided in the middle of the partition 1352, a motor 1354 is provided at the inner bottom of the material receiving bin 135, a screw rod 1355 is adaptively passed through the threaded sleeve 1353, the motor 1354 is used to drive the screw rod 1355 to rotate, a discharge port 1356 is provided on the outer wall of the material receiving bin 135, and the lower end of the partition 1352 is close to the discharge port 1356. The lower end of the partition 1352 can be moved to the bottom of the discharge port 1356; one end of the screw rod 1355 is connected to the output shaft of the motor 1354, and the other end of the screw rod 1355 is close to the top of the receiving bin 135. The other end of the screw rod 1355 is provided with a plurality of dividing strips 1357, and the dividing strips 1357 can rotate synchronously with the screw rod 1355. An exhaust pipe 1358 is also provided on the outer wall of the receiving bin 135. The exhaust pipe 1358 is located between the dividing strips 1357 and the discharge port 1356, and the exhaust pipe 1358 is used to extract the air in the receiving bin 135.

[0050] When the tray 112 is located at the feeding station, the push rod of the receiving cylinder 131 extends, so that the vertical plate 132 and the scraper 133 are away from the receiving cylinder 131. When the stripped tray 112 moves to the bottom of the receiving mechanism 13, the scraper plate is located on one side of the tray 112, and the high position of the guide plate 1351 is located on the other side of the tray 112. Then the push rod of the receiving cylinder 131 retracts. Since the bottom of the scraper plate 133 is flush with the top of the tray 112, the scraper plate 133 can scrape the workpiece 2 on the tray 112 onto the guide plate 1351 when it is reset synchronously with the push rod of the receiving cylinder 131. Under the guiding action of the guide plate 1351, the workpiece 2 can be scraped into the receiving bin 135. The scraper 133 is made of rubber material and is connected to the vertical plate 132 by bolts 1330. In this way, scrapers 133 of different lengths can be replaced according to different usage conditions, so that the scraper 133 can complete the recycling of all workpieces 2 at one time, or complete the recycling of a row of workpieces 2.

[0051] See also Figure 2 and Figure 7 Before the material receiving mechanism 13 receives the material, the motor 1354 drives the screw rod 1355 to rotate. Since the screw rod 1355 and the threaded sleeve 1353 are threadedly connected and the partition 1352 is in contact with the inner wall of the square receiving bin 135, the screw rod 1355 can drive the partition 1352 to move upward during the rotation, so that the discharge port 1356 is located below the partition 1352, and the partition 1352 can be close to the guide plate 1351, thereby preventing the workpiece 2 from falling too far and being damaged. When there are more workpieces 2 stored on the partition 1352, the motor 1354 drives the screw rod 1355 to rotate in the opposite direction, so that the partition 1352 moves downward, and the workpiece 2 is discharged to the outside of the cabinet 11 through the discharge port 1356. Furthermore, during the rotation of the screw rod 1355, the dividing plate will also rotate synchronously, and the dividing plate can be made of soft materials such as sponge. In this way, the dividing plate can sweep a number of workpieces 2, thereby beating out the waste dust adhering to the surface of the workpiece 2 during the paint stripping process, and then draw it out through the exhaust pipe 1358, thereby effectively improving the quality of the workpiece 2.

[0052] Furthermore, a visual inspection unit 136 is also provided on the connecting rod 134, and the visual inspection unit 136 is used to perform an appearance inspection on the workpiece 2 on the pallet 112. In the process of the pallet 112 moving from the feeding mechanism 12 to the paint stripping mechanism 14, the visual inspection unit 136 can perform an appearance inspection on the unstripped workpiece 2 on the pallet 112. At this time, the pallet 112 will move to the paint stripping mechanism 14 only after all the appearance inspections are qualified. After the paint stripping is completed and the pallet 112 moves from the paint stripping mechanism 14 to the feeding mechanism 12, the visual inspection unit 136 can perform an appearance inspection on the workpiece 2 on the pallet 112 that has been stripped of paint. At this time, the receiving cylinder 131 will start the receiving operation only after all the appearance inspections are qualified. If there are unqualified products, they can be taken out manually or by a robot, and then the receiving cylinder 131 drives the scraper 133 to collect all the workpieces 2 into the receiving bin 135.
