Description

Technical Field

[0001] This invention relates to the field of automated production technology for soft magnetic alloy products, specifically to a spraying method for workpieces and a spraying system using the same. Background Technology

[0002] In current workpiece production processes, magnetic rings or cores require spraying and baking. Currently, the industry standard for transferring sprayed workpieces to the baking line involves manual collection on pallets. During the spraying process, workpieces are typically placed directly on pallets for electrostatic spraying. This results in a complete coating on both the workpiece and the pallet. When the entire pallet is transferred to the baking line, the workpiece and pallet tend to stick together, causing "burrs" to appear on the baked workpiece after detachment. Furthermore, coating residue adheres to the pallets, requiring cleaning after each spraying cycle. This cleaning process is time-consuming, labor-intensive, and wastes spraying material. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a spraying method for workpieces and a spraying system using the same.

[0004] A method for spraying a workpiece includes the following steps: S1, moving the workpiece from a first conveying unit to a first comb tooth group; S2, supporting the workpiece with a transfer comb tooth group, causing the workpiece to leave the first comb tooth group; S3, using the transfer comb tooth group to move the workpiece to a second comb tooth group position, and placing the workpiece on the second comb tooth group; S4, moving the workpiece from the second comb tooth group to a second conveying unit position; during the execution of steps S2 to S4, the workpiece is sprayed with paint, and part of the paint during the spraying process flows in the comb tooth space of the first comb tooth group, the second comb tooth group, or the transfer comb tooth group.

[0005] Furthermore, a first supporting surface is provided on the upper side of the first comb tooth group, and a first driving supporting surface is provided on the first conveying part for driving and supporting the workpiece; in step S1, the first conveying part drives the workpiece to approach the position of the first comb tooth group, and the first supporting surface and the first driving supporting surface are horizontally aligned, so that the workpiece is subjected to force and moves from the first driving supporting surface to the first supporting surface.

[0006] Furthermore, a second support surface is provided on the upper side of the second comb tooth assembly, and a second drive support surface is provided on the second conveying part for driving and supporting the workpiece; in step S4, the second comb tooth assembly drives the workpiece closer to the position of the second conveying part, and the second support surface is horizontally aligned with the second drive support surface, so that the workpiece is subjected to force and moves from the second support surface to the second drive support surface.

[0007] Furthermore, the comb space in the first comb group and the comb space in the second comb group are connected in a one-to-one correspondence; the transfer comb group acts on the displacement movement of supporting and transferring the workpiece within the comb space in the connected first and second comb groups.

[0008] Furthermore, during the spraying process, some of the paint is guided to the paint collection section through the comb space in the first comb group, the second comb group, or the transfer comb group.

[0009] A spraying system employing the spraying method described above includes a first conveying section, a second conveying section, and a transfer mechanism disposed between the first conveying section and the second conveying section. The transfer mechanism includes a first comb tooth group, a second comb tooth group, and a transfer comb tooth group. A spraying device is disposed beside the transfer mechanism.

[0010] Furthermore, the first conveying part is used as a transmission belt structure, which includes drive shafts arranged in parallel at both ends, with belts wound around the drive shafts at both ends, and a first drive support surface formed on the upper side of the belts.

[0011] Furthermore, the first comb tooth group includes a plurality of first comb tooth blocks arranged vertically side by side. Each of the first comb tooth blocks arranged side by side has a first supporting surface on its upper side. Each of the first comb tooth blocks arranged side by side has a first concave position on the side away from the second comb tooth group. The upper part of the first concave position is close to the upper side of the first comb tooth group. The first supporting surface is horizontally arranged, the first driving supporting surface is horizontally arranged, and the concave shape of the first concave position is an arc shape that matches the outer circumference shape of the driving shaft.

[0012] Furthermore, the transfer comb group includes multiple vertically arranged transfer comb blocks, each of which has a transfer support surface on its upper side, and each of which has a transfer concave position on the side corresponding to the position of the first comb group, with the upper part of the transfer concave position close to the upper side of the transfer comb group.

[0013] Furthermore, the first conveying unit and / or the second conveying unit and / or the first comb tooth group and / or the second comb tooth group and / or the transfer comb tooth group are connected to a moving drive mechanism that drives them to make relative movement.

[0014] The beneficial effects of this invention are as follows:

[0015] By setting up a spraying method, the magnetic ring or core workpiece can be sprayed in a coordinated manner during the transfer between two processing steps, thereby effectively improving the processing efficiency of the workpiece.

[0016] By setting up the spraying method, the spraying system can not only meet the requirements for transferring workpieces between two processing lines, but also effectively guide and collect the paint during the spraying process through the corresponding comb space, thus saving paint.

[0029] To make the technical solution, objectives, and advantages of the present invention clearer, the following description is provided in conjunction with the appendix. Figures 1 to 4 The present invention will be further explained and illustrated through the examples and embodiments.

[0030] The spraying system of the present invention includes a conveying device for transferring a workpiece 7 from a previous processing step to a spraying step and a baking step. The conveying device includes a first conveying section 4 and a second conveying section 5. The first conveying section 4 and the second conveying section 5 are unidirectionally arranged in a horizontal direction. Along the conveying direction of the first conveying section 4 and the second conveying section 5, the first conveying section 4 is provided with a first input end 41 and a first output end 42, and the second conveying section 5 is provided with a second input end 51 and a second output end 52. The first input end 41 is located near the side of the previous processing step, and the second output end 52 is located corresponding to the side of the baking step. A transfer mechanism is provided between the first output end 42 and the second input end 51. The transfer mechanism includes a first comb tooth group 1 located near the first output end 42, a second comb tooth group 2 located near the second input end 51, and a transfer comb tooth group 3 that moves freely in the comb tooth space between the first comb tooth group 1 and the second comb tooth group 2. The first comb tooth group 1, the second comb tooth group 2, and the transfer comb tooth group 3 are all composed of multiple vertically arranged comb tooth blocks. A corresponding comb tooth space is formed between each comb tooth block in each comb tooth group. The width of the comb tooth space between each comb tooth block is smaller than the width of the workpiece 7 to meet the support requirements of the workpiece 7 on the upper side of the corresponding comb tooth group. A spraying device is provided beside the transfer mechanism.

[0031] During the operation of the spraying system, after the workpiece 7 is processed in the previous processing step, it is moved from the position of the first input end 41 to the position of the transfer mechanism under the conveying of the first conveying part 4, and then moved to the second conveying part 5 under the transfer action of the transfer mechanism. During this period, the spraying device sprays the workpiece 7 on the transfer mechanism with paint. The sprayed workpiece 7 is then conveyed by the second conveying part 5 to the position of the second output end 52 in preparation for the baking process.

[0032] Based on the application of the corresponding comb tooth structure combination of the transfer mechanism, the workpiece 7 can be effectively transferred between the first conveying part 4 and the second conveying part 5. At the same time, it can be ensured that during the spraying process of the workpiece 7, the sprayed paint can flow away with the comb tooth space between the corresponding comb tooth structure. This can avoid the paint from accumulating on the transfer mechanism in large quantities, thereby reducing the need for cleaning the transfer mechanism. At the same time, it can also prevent the accumulated paint from adhering too much to the workpiece 7, which would result in an uneven paint layer on the workpiece 7.

[0033] In a preferred embodiment, a paint collection section may be provided on the lower side of the transfer mechanism to collect the paint flowing out of the corresponding comb tooth space for subsequent reuse, thereby reducing paint waste.

[0034] The first comb tooth group 1 is positioned at the same horizontal height as the second comb tooth group 2. The first comb tooth group 1 and the second comb tooth group 2 are arranged along the conveying direction of the first conveying part 4 and the second conveying part 5. The comb tooth space between the first comb tooth group 1 and the second comb tooth group 2 forms a one-to-one corresponding connection. The transfer comb tooth group 3 forms a comb tooth interleaving with the first comb tooth group 1 and the second comb tooth group 2. Then, each comb tooth block in the transfer comb tooth group 3 can freely intersect and move in the comb tooth space between the connected and cooperating first comb tooth group 1 and the second comb tooth group 2 under the drive of the corresponding moving drive mechanism.

[0035] The first conveying unit 4 and / or the second conveying unit 5 and / or the first comb tooth group 1 and / or the second comb tooth group 2 and / or the transfer comb tooth group 3 are connected to a moving drive mechanism to drive them to move, so that the first conveying unit 4, the second conveying unit 5, the first comb tooth group 1, the second comb tooth group 2 and the transfer comb tooth group 3 can generate relative moving actions, and with the coordinated moving actions of each structure, a corresponding magnetic core transfer application is realized.

[0036] In this spraying system, the transfer mechanism operates on the following principle for transferring workpiece 7:

[0037] Based on the comb tooth space arrangement of each comb tooth group, the transfer comb tooth group 3 can move interlaced within the comb tooth space between the first comb tooth group 1 and the second comb tooth group 2. When the first conveying unit 4 conveys the workpiece 7 onto the first comb tooth group 1 located at its first output end 42, under the action of the corresponding moving drive mechanism, the transfer comb tooth group 3 rises through the comb tooth space of the first comb tooth group 1, supporting the workpiece 7 and allowing it to leave the first comb tooth group 1. Then, the transfer comb tooth group 3 moves into the comb tooth space of the second comb tooth group 2, and descends, supporting the descending workpiece 7 onto the second comb tooth group 2. Finally, the second comb tooth group 2 comes into contact with the second conveying unit 5, and the second conveying unit 5 carries the workpiece 7 away, completing the transfer action between the workpiece 7 and the first and second conveying units 4 and 5.

[0038] Specifically, to achieve coordinated transfer actions, the first conveying unit 4 and the second conveying unit 5 can be applied as a transmission belt structure in the prior art. The transmission belt structure includes two drive shafts arranged parallel to the horizontal plane, with belts wound around the two drive shafts. The transmission drive directions of the two sets of transmission belt structures are the same, and the upper belt end face of the corresponding transmission belt structure is set as a drive support surface for driving and supporting the workpiece 7. Therefore, the first conveying unit 4 is provided with a first drive support surface 43 for driving and supporting the workpiece 7, and the second conveying unit 5 is provided with a second drive support surface 53 for driving and supporting the workpiece 7; the first drive support surface 43 and the second drive support surface 53 are at the same horizontal height and are arranged parallel to each other.

[0039] The transfer mechanism is located between adjacent drive shafts on both sides of the two sets of transmission belt structures.

[0040] The first comb tooth group 1 includes a plurality of vertically arranged first comb tooth blocks 10. Each of the parallel first comb tooth blocks 10 has a horizontally arranged first support surface 11 on its upper side. Each of the parallel first comb tooth blocks 10 has a first concave position 12 on the side away from the second comb tooth group 2. The first concave position 12 is arranged in an arc shape corresponding to the first conveying part 4 and matches the outer peripheral shape of the drive shaft in the first conveying part 4. The upper part of the first concave position 12 is close to the upper side of the first comb tooth group 1.

[0041] The second comb group 2 includes a plurality of vertically arranged second comb blocks 20. Each of the parallel second comb blocks 20 has a horizontally arranged second support surface 21 on its upper side. Each of the parallel second comb blocks 20 has a second concave position 22 on the side away from the first comb group 1. The second concave position 22 is arranged in an arc shape corresponding to the second conveying part 5 and matches the outer circumferential shape of the drive shaft in the second conveying part 5. The upper part of the second concave position 22 is close to the upper side of the second comb group 2.

[0042] The transfer comb group 3 includes a plurality of vertically arranged transfer comb blocks 30. Each of the parallel transfer comb blocks 30 has a horizontally arranged transfer support surface 31 on its upper side. Each of the parallel transfer comb blocks 30 has a transfer concave position 32 on the side corresponding to the position of the first comb group 1. The transfer concave position 32 is arranged in an arc shape corresponding to the first conveying part 4 and matches the outer circumferential shape of the drive shaft in the first conveying part 4. The upper part of the transfer concave position 32 is close to the upper side of the transfer comb group 3.

[0043] As a preferred structural arrangement, a first connecting plate 13 is provided laterally on the lower side of the first comb tooth group 1. The first connecting plate 13 is fixedly connected to each of the first comb tooth blocks 10. The first concave position 12 is located at the upper part of each of the first comb tooth blocks 10 arranged side by side away from the second comb tooth group 2.

[0044] A second connecting plate 23 is provided horizontally on the lower side of the second comb tooth group 2. The second connecting plate 23 is fixedly connected to each of the second comb tooth blocks 20. The second concave position 22 is provided on the upper part of each of the side-by-side second comb tooth blocks 20 away from the first comb tooth group 1.

[0045] In the transfer comb group 3, the transfer concave position 32 is located on the upper part of the side of the transfer comb group 3 corresponding to the first comb group 1, and the transfer drive section 33 is horizontally extended on the lower part of the side of the transfer comb group 3 corresponding to the first comb group 1. The transfer comb group 3 is connected to the first comb group 1 through the upper side of the first connecting plate 13, and the transfer drive section 33 is located at the lower part of the first comb group 1.

[0046] The moving drive mechanism includes a first lifting mechanism 61 and a first translation mechanism 62 connected to the transfer drive section 33. Driven by the first lifting mechanism 61, the transfer comb tooth group 3 can move vertically up and down within the comb tooth space of the corresponding connected first comb tooth group 1 and second comb tooth group 2; driven by the first translation mechanism 62, the transfer comb tooth group 3 can move horizontally within the comb tooth space of the corresponding connected first comb tooth group 1 and second comb tooth group 2.

[0047] The moving drive mechanism also includes a second translation mechanism 63 connected to the second comb tooth group 2. Under the drive of the second translation mechanism 63, the second comb tooth group 2 makes a reciprocating driving motion in the horizontal direction, moving closer to or away from the first comb tooth group 1.

[0048] The first conveying section 4 and the second conveying section 5 are fixedly arranged, and the first comb tooth group 1 is positioned and abuts against the discharge end of the first conveying section 4; a reserved space larger than the size of the first comb tooth group 1 and the second comb tooth group 2 is reserved between the first conveying section 4 and the second conveying section 5. Under the drive of the second translation mechanism 63, the driving motion of the second comb tooth group 2 away from the first comb tooth group 1 causes the second comb tooth group 2 to abut against the position of the second conveying section 5.

[0049] Specifically, the spraying method for workpiece 7 in this spraying system can be summarized as follows:

[0050] A method for spraying a workpiece 7, comprising the following steps:

[0051] S1. The first conveying unit 4 moves the workpiece 7 to the first comb tooth group 1.

[0052] S2. Drive the transfer comb group 3 to support the workpiece 7 and cause the workpiece 7 to leave the first comb group 1.

[0053] S3. Drive the transfer comb group 3 so that the transfer comb group 3 moves the workpiece 7 to the position of the second comb group 2 and places the workpiece 7 on the second comb group 2.

[0054] S4. Drive the second comb tooth group 2 to move the workpiece 7 to the position of the second conveying part 5;

[0055] S5. The second conveying unit 5 is used to move the workpiece 7 to the next process.

[0056] During the execution of steps S2 to S4, the workpiece 7 is sprayed with paint, and part of the paint during the spraying process flows in the comb space of the first comb group 1, the second comb group 2, or the transfer comb group 3.

[0057] In step S1, when the first conveying unit 4 uses its first driving support surface 43 to bring the workpiece 7 to the position of the first comb group 1, the first support surface 11 and the first driving support surface 43 are horizontally aligned. Then, under the transmission action of the corresponding belt drive structure, the workpiece 7 moves from the first driving support surface 43 to the first support surface 11 under the driving inertia pushed by the first belt conveying unit. This satisfies the application requirements for workpiece 7 transfer between the first conveying unit 4 and the first comb group 1.

[0058] Based on the setting of the first concave position 12, the first comb tooth group 1 is set close to the first conveying part 4, thereby meeting the application requirements for the transfer of workpiece 7 between the first conveying part 4 and the first comb tooth group 1; then in the actual driving process, in order to ensure stable conveying, the speed of the belt-driven first conveying part 4 should not be set too fast; so that when the speed of the first conveying part 4 is coordinated with the workpiece 7 transfer action between the first conveying part 4 and the first comb tooth group 1, the workpiece 7 will move more than halfway to the upper edge position of the first comb tooth group 1.

[0059] Based on the fact that the upper part of the transfer concave position 32 of the transfer comb group 3 is close to the upper side of the transfer comb group 3, the transfer comb group 3 can be smoothly moved to the upper edge position of the first comb group 1 through lifting and translating actions, with the cooperation of the structure. At this time, the transfer support surface 31 is flush with the first drive support surface 43, so that the upper outer edge of the transfer comb group 3 replaces the position of the first comb group 1 to meet the application of lifting support for the workpiece 7.

[0060] In step S4, when the second comb group 2 uses its second supporting plane to bring the workpiece 7 close to the position of the second conveying part 5, the second supporting plane is horizontally aligned with the second driving supporting surface 53, and the workpiece 7 moves from the second supporting plane to the second driving supporting surface 53 under the traction of the second conveying part 5.

[0061] Similarly, based on the fact that the upper part of the second concave position 22 of the second comb tooth group 2 is close to the upper side of the second comb tooth group 2, the second comb tooth group 2 and the second conveying part 5 can form a cooperative cooperation between the belt and the comb tooth structure, so that its second supporting surface 21 and the second driving supporting surface 53 are flush, which satisfies the transfer preparation of the workpiece 7.

[0062] Before the second comb tooth group 2 supports the workpiece 7, the second comb tooth group 2 is positioned close to the first comb tooth group 1. Based on the reserved space therein, under the drive of the corresponding moving drive mechanism, the transfer comb tooth group 3 can be moved through the comb tooth space in the second comb tooth group 2 to a position away from the first comb tooth group 1. The transfer comb tooth group 3 is driven in a linkage manner to place the workpiece 7, located on the outer edge of the upper side of the transfer comb tooth group 3 near the first comb tooth group 1, onto the upper edge of the second comb tooth group 2 near the second conveying part 5, so that the second comb tooth group 2 supports the workpiece 7, with the lower half of the workpiece 7 suspended in the air.

[0063] The second comb tooth group 2 is driven to the position of the second conveying part 5. The second concave position 22 is engaged with the second input end 51 of the second conveying part 5. The second supporting surface 21 is flush with the second driving supporting surface 53. Under the friction transmission traction of the corresponding belt, the workpiece 7 moves from the second comb tooth group 2 to the second conveying part 5.

[0064] The paint collection unit can be configured to be positioned corresponding to the first comb group 1, the second comb group 2, or the transfer comb group 3.

[0065] The above description is only a preferred embodiment of the present invention. For those skilled in the art, modifications can still be made to the embodiments without departing from the implementation principle of the present invention, and the corresponding modifications should also be considered within the protection scope of the present invention.
