Description

Technical Field

[0001] The utility model relates to the technical field of coating equipment, in particular to a button coating device and a color separation coating system. Background Art

[0002] In the field of coating, the sophistication of the process and the operational procedures directly impact the market competitiveness of products. Especially in the era of prevalent electronic products, in order to enhance the aesthetics of product housings and win consumer favor, metal-like or graphite-like coatings are often applied to the surface of the housings.

[0003] Among these, surface-coated buttons are an emerging type of button style. Surface-coated buttons refer to buttons that have been treated and modified on the surface before being plated. Alternatively, they can be plated first and then treated or modified, thereby creating a variety of patterns or font effects on the button surface. However, the existing production process for coated buttons still limits their development. The current conventional production method is to spray primer on the button surface → apply ink → plate → remove ink → post-process. This involves many production steps, resulting in relatively high costs and low production efficiency.

[0004] At present, the applicant adopts the method of applying transparent paint before coating the button surface, replacing the two steps of "applying ink and removing ink", which is conducive to shortening the process. However, since the manual operation coating method is greatly affected by the workers' technical level, it is easy to cause inconsistent coating quality of the buttons. Therefore, it is very necessary to develop a mechanical coating device. Utility Model Content

[0005] In view of the shortcomings of the prior art, the first purpose of the present invention is to provide a button coating device, which achieves the purpose of improving the consistency of coating quality by mechanically applying transparent paint.

[0006] The second purpose of the present invention is to provide a color separation coating system, which has the advantage of improving work efficiency.

[0007] To achieve the above first purpose, the present invention provides the following technical solutions:

[0008] A button coating device comprises a workbench, a coating roller, a transfer head group, and a workpiece mounting seat, a horizontal drive mechanism and a lifting drive mechanism arranged on the workbench. A coating template and a coating groove are arranged in sequence on the workbench in a direction away from the workpiece mounting seat. The coating roller is arranged at the output end of the horizontal drive mechanism through an elastic member, and the rolling path of the coating roller passes through the surface of the coating groove and the coating template in sequence. The transfer head group is arranged at the output end of the horizontal drive mechanism and the lifting drive mechanism, and the moving path of the transfer head group passes through the surface of the coating template and the workpiece mounting seat in sequence.

[0009] By adopting the above technical solution, the workpieces are first arranged and mounted on the workpiece mounting seat manually or mechanically to facilitate subsequent coating operations; the coating roller is then driven to roll on the surface of the coating groove and the coating template by the horizontal drive mechanism. At this time, the pre-pressure of the elastic member is utilized to keep the roller surface of the coating roller in contact with the surface of the coating groove and the coating template, thereby coating the transparent paint in the coating groove onto the coating template and forming a paint film of a predetermined pattern on the coating template; in the process of coating the transparent paint by the coating roller, the lifting drive mechanism drives the transfer head group to contact the coating template, and the corresponding paint film is transferred to the transfer head group for the subsequent coating operation of the coating roller, and then the horizontal drive mechanism and the lifting drive mechanism drive the transfer head group to contact the coating template, and the corresponding paint film is transferred to the transfer head group for the subsequent coating operation of the coating roller. The descending drive mechanism drives the transfer head group in turn to move so that the transfer head group contacts the workpiece on the workpiece mounting seat and transfers the corresponding paint film to the surface of the workpiece to complete the coating operation; then the above workpiece is removed and the above mechanical operation is performed reciprocally; in this process, the movable coating roller and transfer head group are used to realize the fixed-point transfer of transparent paint and paint film, and the coating pattern and workpiece position are limited by the coating template and the workpiece mounting seat, which directly eliminates the shortcomings of the original manual coating method. After the initial coating pattern and coating position are determined, the coating quality of the workpiece is controlled by the machine, which can ensure the consistency of coating quality while taking into account high efficiency.

[0010] The button coating device further includes a scraper positioned between the coating roller and the transfer head assembly. The scraper is mounted at the output end of the horizontal drive mechanism such that its blade contacts the surface of the coating template. After the coating roller applies clear lacquer to the surface of the coating template, the scraper scrapes excess clear lacquer back into the coating trough as it moves toward the coating trough. This prevents over-coating by the coating roller, ensuring that the clear lacquer forms a predetermined pattern while reducing costs.

[0011] Furthermore, the horizontal position of the elastic member and scraper on the horizontal drive mechanism is adjustable. The position of the coating roller and scraper can be adjusted according to the location of the paint film formed on the coating template, which improves versatility. Preferably, the length direction of the coating roller and scraper is perpendicular to the drive direction of the horizontal drive mechanism, and the horizontal position adjustment direction of the elastic member and scraper is perpendicular to the drive direction of the horizontal drive mechanism.

[0012] Specifically, the output end of the horizontal drive mechanism is provided with a connecting column, and a T-slot is provided on the connecting column. The length direction of the T-slot is perpendicular to the driving direction of the horizontal drive mechanism, and a slide is slidably connected to the T-slot, and at least two hexagonal bolts passing through the slide, and these hexagonal bolts are threadedly connected with fastening nuts that interfere with the surface of the slide, and the elastic member and scraper are arranged on the slide.

[0013] More specifically, the elastic member includes a lifting slot arranged on the slide seat, a slide rod slidingly passed through the lifting slot, a lifting slide plate slidably connected to the lifting slot and fixed on the slide rod, and a spring sleeved on the slide rod. The coating roller is rotatably mounted on the lifting slide plate, and the two ends of the spring are respectively fixed on the lifting slot and the slide rod to force the coating roller to move away from the lifting slot.

[0014] Furthermore, the inner wall of the coating trough close to the coating template is provided with an arc-shaped concave guide wall, which is used to guide the coating roller to move toward the coating template, so that the coating roller can move more smoothly between the coating trough and the coating template.

[0015] Furthermore, the four edges of the workbench extend upward to form flanges, which surround the coating template and the coating trough. A height difference exists between the top surface of the flange and the top surface of the coating template and the coating trough. The flanges prevent excess clear paint from spilling, maintaining a clean workshop environment.

[0016] Furthermore, the workpiece mounting base includes a mounting plate, a plurality of abutting portions disposed on the mounting plate, fixtures that abut against the abutting portions, and a plurality of mounting holes formed in the fixtures. The mounting holes are used to insert the workpieces. The fixtures carrying the workpieces are then replaced with the previous set of fixtures and abutted against the abutting portions to complete the workpiece installation, shortening the time required for loading and unloading the workpieces and improving work efficiency.

[0017] Furthermore, a three-dimensional slide is installed between the workbench and the mounting plate. Since the position of the abutment portion is relatively fixed, if the coating pattern or specifications of the workpiece are changed, the coating template can be replaced and the three-dimensional slide is used to adjust the installation position of the workpiece on the tooling to match the transfer head assembly, thus quickly adapting to the processing state of different workpieces, which has excellent versatility.

[0018] Specifically, the three-dimensional slide includes a first slide arranged on the workbench, a first nut arranged on the first slide, a second slide slidably connected to the first slide, a first screw rod threadedly connected to the first nut and rotatably connected to the second slide, a third slide slidably connected to the second slide, a second nut arranged on the third slide, a second screw rod rotatably connected to the second slide and threadedly connected to the second nut, a third nut arranged on the mounting plate, and a third screw rod rotatably connected to the third slide and threadedly connected to the third nut. The mounting plate is slidably connected to the third slide, and the axial center lines of the first screw rod, the second screw rod and the third screw rod are perpendicular to each other.

[0019] Furthermore, the lifting drive mechanism is disposed at the output end of the horizontal drive mechanism, and the transfer head assembly is disposed at the output end of the lifting drive mechanism via a horizontal adjustment member, and the horizontal position of the transfer head assembly on the lifting drive mechanism is adjustable. The position of the transfer head assembly can be adjusted according to the position of the paint film formed on the coating template, which is conducive to improving versatility.

[0020] The lifting mechanism is a lifting mechanism that is a lifting mechanism of the lifting platform and a lifting mechanism of the lifting platform. The lifting mechanism is a lifting mechanism that is a lifting mechanism of the lifting platform and a lifting mechanism of the lifting platform. The lifting mechanism is a lifting mechanism that is a lifting mechanism of the lifting platform and a lifting mechanism of the lifting platform. The lifting mechanism is a lifting mechanism that is a lifting mechanism of the lifting platform and a lifting mechanism of the lifting platform. The lifting mechanism is a lifting mechanism that is a lifting mechanism of the lifting platform and a lifting mechanism of the lifting platform.

[0021] Furthermore, the transfer head group is detachably connected to the horizontal adjustment member, and the transfer head group can be replaced according to the formation position of the paint film on the coating template, which is conducive to improving versatility.

[0022] Specifically, the surface of the coating template has a plurality of grooves arranged according to a predetermined coating pattern, and the transfer head group includes a flexible mounting sleeve mounted on the positioning seat, and a flexible protrusion arranged on the bottom surface of the mounting sleeve, and the protrusion, the groove and the mounting hole are arranged in a one-to-one correspondence.

[0023] To achieve the above second purpose, the present invention provides the following technical solutions:

[0024] A color separation coating system includes a belt conveyor, a plurality of coating devices, and an oven. The coating devices are evenly distributed on one side of the belt conveyor, and the oven is arranged downstream of the coating devices and is covered on the conveying surface of the belt conveyor.

[0025] By adopting the above technical solution, the belt conveyor is used to drive the unprocessed workpiece toward the coating device for coating operations, and is used to drive the coated workpiece toward the oven to promote the paint film on the workpiece to dry and solidify and not fall off easily. It shortens the time for the workpiece to be transferred between the two processes, which is conducive to improving work efficiency.

[0026] Furthermore, the belt conveyor is provided with a plurality of photoelectric switches, a drive cylinder electrically connected to the photoelectric switches, and a transfer member disposed on the piston rod of the drive cylinder. The photoelectric switches are arranged upstream of the coating device with the detection head facing the conveying surface of the belt conveyor. The movement path of the transfer member passes through the conveying surface of the belt conveyor and the workpiece mounting seat. Unprocessed workpieces are pre-placed on the side of the belt conveyor near the coating device. When the workpiece or the tooling with the workpiece passes through the sensing range of the photoelectric switches, the photoelectric switches control the operation of the drive cylinder and the transfer member. The transfer member transfers the workpiece or the tooling with the workpiece by suction or clamping, thereby replacing the manual process of transferring unprocessed or coated workpieces. The coated workpiece is transferred to the side of the belt conveyor away from the coating device to avoid being sensed by the photoelectric switches, thereby improving work efficiency. In addition, a gap is provided between the piston rod of the drive cylinder and the conveying surface of the belt conveyor for the workpiece and / or tooling to pass through, thereby facilitating the passage of coated workpieces transported from upstream.

[0027] Specifically, the transfer member is configured as a vacuum suction cup, a magnetic member or a pneumatic finger.

[0028] In summary, the beneficial technical effects of the present invention are:

[0029] The coating device of the utility model realizes the fixed-point transfer of the transparent paint and its film through the movable coating roller and transfer head group, and limits the coating pattern and workpiece position through the coating template and workpiece mounting seat, which directly eliminates the shortcomings of the original manual coating method. After the initial coating pattern and coating position are determined, the coating quality of the workpiece is mechanically controlled, which can ensure the consistency of coating quality while taking into account high efficiency.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the present invention is further explained below with reference to the accompanying drawings and specific implementation methods.

[0039] Example 1: Reference Figure 1 The present invention discloses a color separation coating system comprising a belt conveyor 1, multiple coating devices 2, a feeding device 3, and an oven 4. The coating devices 2 are evenly distributed on one side of the belt conveyor 1, and the feeding device 3 is arranged in conjunction with the coating devices 2. The feeding device 3 uses photoelectric sensing to achieve horizontal transfer of workpieces between the belt conveyor 1 and the coating devices 2. The oven 4 is arranged downstream of the coating devices 2 and is mounted on the conveying surface of the belt conveyor 1. This allows the coated workpieces to pass through the oven 4 during transportation, thereby drying and solidifying the paint film on the workpieces and preventing them from falling off.

[0040] Reference Figure 1 and Figure 2 Specifically, the coating device 2 includes a workbench 5, a coating roller 53, a transfer head group 6, a workpiece mounting seat 7 provided on the workbench 5, and a horizontal driving mechanism 8 (refer to Figure 4 ) and a lifting drive mechanism 9. The workbench 5 is mounted on the belt conveyor 1, and the upper surface of the workpiece mounting seat 7 is flush with the belt conveyor 1 to facilitate horizontal movement of the workpiece. A coating template 51 and a coating trough 52 are sequentially arranged on the workbench 5 in a direction away from the workpiece mounting seat 7. The coating roller 53 is arranged at the output end of the horizontal drive mechanism 8 through an elastic member 54, and the rolling path of the coating roller 53 passes through the coating trough 52 and the surface of the coating template 51 in sequence. The transfer head group 6 is arranged at the output end of the horizontal drive mechanism 8 and the lifting drive mechanism 9, and the moving path of the transfer head group 6 passes through the coating template 51 and the surface of the workpiece mounting seat 7 in sequence.

[0041] The loading device 3 comprises a photoelectric switch 31 mounted on the belt conveyor 1, a drive cylinder 32 electrically connected to the photoelectric switch 31, and a transfer member 33 mounted on the piston rod of the drive cylinder 32. The photoelectric switch 31 is positioned upstream of the coating device 2, with its detection head facing the conveying surface of the belt conveyor 1. The transfer member 33 is configured as a pneumatic finger for gripping the workpiece 73, with its movement path passing through the conveying surface of the belt conveyor 1 and the workpiece mounting base 7.

[0042] During coating, the unprocessed workpiece is pre-placed on the side of the belt conveyor 1 near the coating device 2. When the workpiece or the tooling 73 with the workpiece passes through the sensing range of the photoelectric switch 31, the photoelectric switch 31 controls the driving cylinder 32 and the transfer member 33 to operate. The transfer member 33 transfers the workpiece or the tooling 73 with the workpiece by clamping and arranges the workpiece on the workpiece mounting seat 7 to facilitate subsequent coating operations. The horizontal drive mechanism 8 then drives the coating roller 53 to roll on the surface of the coating groove 52 and the coating template 51. At this time, the pre-pressure of the elastic member 54 can keep the roller surface of the coating roller 53 in contact with the surface of the coating groove 52 and the coating template 51, thereby applying the transparent paint in the coating groove 52 to the coating template 51 and forming a paint film with a predetermined pattern on the coating template 51. During the coating process of the coating roller 53, the lifting drive mechanism 9 drives the transfer head assembly 6 to contact the coating template 51, transferring the corresponding paint film to the transfer head assembly 6 for the subsequent coating operation of the coating roller 53. Then, the horizontal drive mechanism 8 and the lifting drive mechanism 9 sequentially drive the transfer head assembly 6 to move the transfer head assembly 6 to contact the workpiece on the workpiece mounting seat 7 and transfer the corresponding paint film to the workpiece surface, thus completing the coating operation. The transfer member 33 then transfers the coated workpiece to the side of the belt conveyor 1 away from the coating device 2 to avoid being sensed by the photoelectric switch 31, and the operation of the next batch of workpieces can be carried out.

[0043] Example 2: Reference Figure 3, a button coating device 2 disclosed in the present invention, differs from Example 1 in that a workpiece mounting base 7 includes a mounting plate 71, two abutting portions 72 disposed on the mounting plate 71, a fixture 73 abutting against the abutting portions 72, and a plurality of mounting holes 74 formed in the fixture 73. The mounting holes 74 are used to insert the workpiece. The fixture 73 carrying the workpiece is then replaced with the previous set of fixtures 73 and abutted against the abutting portions 72 to complete the installation of the workpiece, shortening the time for loading and unloading the workpiece and improving work efficiency.

[0044] At the same time, a three-dimensional slide 75 is provided between the workbench 5 and the mounting plate 71. Since the position of the abutment portion 72 is relatively fixed, when the coating pattern or specification of the workpiece is changed, the coating template 51 can be replaced and the mounting position of the workpiece on the tooling 73 can be adjusted to match the transfer head assembly 6 via the three-dimensional slide 75, thereby quickly adapting to the switching of processing states of different workpieces, which has good versatility.

[0045] The three-dimensional slide 75 includes a first slide 751 provided on the workbench 5, a first nut 752 provided on the first slide 751, a second slide 753 slidably connected to the first slide 751, a first screw rod 754 threadedly connected to the first nut 752 and rotatably connected to the second slide 753, a third slide 755 slidably connected to the second slide 753, a second nut 756 provided on the third slide 755, a second screw rod 757 rotatably connected to the second slide 753 and threadedly connected to the second nut 756, a third nut 758 provided on the mounting plate 71, and a third screw rod 759 rotatably connected to the third slide 755 and threadedly connected to the third nut 758. The mounting plate 71 is slidably connected to the third slide, and the axes of the first screw rod 754, the second screw rod 757, and the third screw rod 759 are perpendicular to each other.

[0046] Example 3: Reference Figure 4 , a button coating device 2 disclosed in the present utility model, differs from Example 1 in that a lifting drive mechanism 9 is disposed at the output end of a horizontal drive mechanism 8. A horizontal adjustment member 10 is provided at the output end of the lifting drive mechanism 9. The transfer head assembly 6 is detachably connected to the horizontal adjustment member 10 to facilitate adjustment of the horizontal position of the transfer head assembly 6. In actual use, the position of the transfer head assembly 6 can be adjusted or replaced according to the position of the paint film formed on the coating template 51, thereby improving versatility.

[0047] The horizontal drive mechanism 8 includes a horizontal cylinder 81 and a pair of horizontal slide rails 82 mounted on the workbench 5, and a horizontal support plate 83 mounted on the piston rod of the horizontal cylinder 81 and slidably connected to the horizontal slide rails 82. The lifting drive mechanism 9 includes a lifting cylinder 91 mounted on the horizontal support plate 83, a pair of lifting slide rails 92 slidably extending through the horizontal support plate 83, and a lifting support plate 93 mounted on the piston rod of the lifting cylinder 91 and on these lifting slide rails 92.

[0048] The horizontal adjustment member 10 includes a first dovetail bar 101 mounted on the lifting support plate 93, a positioning base 102 mounted on the transfer head assembly 6, a second dovetail bar 103 mounted on the positioning base 102, a connecting base 104 slidably connected to the first dovetail bar 101 and the second dovetail bar 103, and a first bolt 105 and a second bolt 106 threadedly connected to the connecting base 104. The end of the first bolt 105 passes through the connecting base 104 and tightly abuts the first dovetail bar 101. The end of the second bolt 106 passes through the connecting base 104 and tightly abuts the second dovetail bar 103. The lengths of the first dovetail bar 101 and the second dovetail bar 103 are perpendicular to each other.

[0049] Example 4: Reference Figure 5 , is a button coating device 2 disclosed in the present invention. The difference from Example 3 is that it also includes a scraper 55 arranged between the coating roller 53 and the transfer head group 6. The scraper 55 is installed on the output end of the horizontal drive mechanism 8 in a manner such that the blade contacts the surface of the coating template 51, and the horizontal position of the elastic member 54 and the scraper 55 on the horizontal drive mechanism 8 is adjustable. At the same time, the length direction of the coating roller 53 and the scraper 55 is perpendicular to the driving direction of the horizontal drive mechanism 8, and the horizontal position adjustment direction of the elastic member 54 and the scraper 55 is perpendicular to the driving direction of the horizontal drive mechanism 8. After the coating roller 53 applies the clear paint to the surface of the coating template 51, the scraper 55 can scrape the excess clear paint back into the coating groove 52 during the movement toward the coating groove 52, so as to avoid the situation where the coating roller 53 applies too much clear paint. While reducing costs, it can ensure that the clear paint can form a paint film with a predetermined pattern.

[0050] The horizontal support plate 83 is provided with a connecting post 56, which is provided with a T-slot 561. The length of the T-slot 561 is perpendicular to the driving direction of the horizontal drive mechanism 8. A slide 57 and a pair of hexagonal bolts 58 are slidably connected to the T-slot 561. These hexagonal bolts 58 are threadedly connected to the slide 57. These hexagonal bolts 58 are threaded with fastening nuts 59 that contact the surface of the slide 57. The elastic member 54 and scraper 55 are mounted on the slide 57 to facilitate horizontal position adjustment. In actual use, the position of the coating roller 53 and scraper 55 can be adjusted according to the position of the paint film formed on the coating template 51, which helps to improve versatility.

[0051] The elastic member 54 includes a lifting slot 541 disposed on the slide 57, a slide rod 542 that slides through the lifting slot 541, a lifting slide plate 543 that is slidably connected to the lifting slot 541 and fixed to the slide rod 542, and a spring 544 that is sleeved on the slide rod 542. The coating roller 53 is rotatably mounted on the lifting slide plate 543. The ends of the spring 544 are respectively fixed to the lifting slot 541 and the slide rod 542 to force the coating roller 53 to move away from the lifting slot 541, thereby maintaining contact between the coating roller 53, the coating slot 52, and the coating template 51.

[0052] Example 5: Reference Figure 6 , a button coating device 2 disclosed in the present invention, differs from Example 3 in that, to improve the convenience of mechanical coating operations, the four edges of the workbench 5 extend upward to form flanges 521. The flanges 521 surround the coating template 51 and the coating trough 52, and there is a height difference between the top surface of the flanges 521 and the top surfaces of the coating template 51 and the coating trough 52. The flanges 521 prevent excess transparent paint from spilling, maintaining a clean workshop environment.

[0053] At the same time, the inner wall of the coating groove 52 close to the coating template 51 is set as an arc-shaped concave guide wall 522. The guide wall 522 is used to guide the coating roller 53 to move toward the coating template 51 so that the coating roller 53 moves between the coating groove 52 and the coating template 51 more smoothly.

[0054] In addition, the surface of the coating template 51 has a plurality of grooves 511 arranged and evenly distributed according to a predetermined coating pattern. The transfer head assembly 6 includes a flexible mounting sleeve 61 that fits over the positioning seat 102 and a flexible protrusion 62 disposed on the bottom surface of the mounting sleeve 61. The protrusion 62, the grooves 511, and the mounting locations on the workpiece mounting seat 7 are arranged in a one-to-one correspondence. The transfer head assembly 6 is detachably connected to the leveling member 10. During actual use, the transfer head assembly 6 can be replaced according to the location of the paint film formed on the coating template 51, which improves versatility.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
